dish machin

Panasonic's dish washer / drier achieved a cumulative production of 10 million units on June 22, 2017. However, the penetration rate of dishwashing dryers in Japan is less than 30%, and it is still "general" compared to Australia and Norway with a penetration rate of over 80%, Sweden over 70% and Germany etc. not. So, while looking back on the history of Panasonic that will continue to make the dishwasher (dishwasher) for nearly 60 years, I tried to actually wash and check the evolution of the latest model.

We will pick up and introduce epoch-like products from dishwashers born in 1960 to the latest models released in 2016. Just looking and having a fun dishwasher history here!

Let's look at the transition of Panasonic's dishwasher

Panasonic has a long history of dishwashers, and the first MR-500 was born in 1960. This is Japan's first fully automatic dishwasher. However, "MR-500" is on the floor and is a style used side by side with the sink, and its appearance is like a washing machine. It is natural that the shape is similar because the body of the washing machine that the company manufactured was used for the dishwasher. A table-type dishwasher "NP-100" was released in 1968, eight years after that. This table-top dishwasher is also Japan's first! It was Uri to use the hot water of the instantaneous water heater and to remove oil stains well. Even after that, with the temperature control function and timer etc. in 1969, it is the basic type of the current dishwasher. Floor type "NP-1000" that appears like this appears, but the spread is still not good, and it is said that the era of not selling at all for about 30 years has continued. It was an opportunity to change the age of such unfortunate, compact table-top dishwasher "NP-600" released in 1986. A sense of size that can be placed on the top plate of the sink is hit, and it seems that about 30,000 units have been sold in a year. Partly because of women's social advancement into society, in 1991 we achieved 500,000 vehicles.

The price of the fully automatic dishwasher "MR-500" that first appeared in Japan is 59,000 yen. This price seems to be hard to sell because it was quite high, about four times less than the starting salary (16,000 yen) of college graduates at that time

The top surface of the "MR-500" is a lid, and put dishes in the open place. In addition, water hose is specifications to connect from the top, and blows out so that it may pour down from metal nozzle in the back of the lid

It seems to be easy to put in a bowl and chopsticks, but it is hard to set a large flat plate. The detergent is also sprinkled from the top of the tableware. It is similar to how old vertical washing machines are used

It may be difficult to put in a bowl and chopsticks, but it is hard to set a large flat plate.

Japan's first table-top dishwasher "NP-100" released in 1968, nicknamed "O-Q" from its shape. As the diet of Western food progressed, it was connected to a water heater, which was rapidly spreading at that time, and the hot water was used to improve the removal of oils. In addition, temperature control of hot water is performed by the side of the instantaneous water heater

Floor-standing type "NP-1000" (sold in 1969), which created the basic structure of the later dishwasher, such as basket design, detergent input method, temperature control and timer.

There are also operations such as "pre-washing" and "disinfecting rinse", and it can be seen that it has evolved considerably

Born in 1986, the "NP-600" is a big hit due to its improved installation. Are there many people who remember the nickname "Kitchen Love Wife" in their memories? "Kitchen Love Wife" is now able to set a large flat plate easily

"Kitchen Love Wife" is now able to set a large flat plate easily

The cleaning course and drying time can also be selected

 

After that, a dishwashing dryer adapted to the Japanese kitchen will be developed more and more. The industry's first 45 cm wide built-in “NP-5500B” compatible with Japanese kitchen width standards was released in 1988, and the built-in “NP-P45X1P1” that can be fully opened in 1999 and a sink side of about 30 cm The slim type desktop type “NP-33S1” that can be installed on the market has appeared. These are the standards that have now become the standard for dishwashers on the market. Thus, it wThe built-in type door used to be a front open that breaks down with a pattern before, but the "NP-P45X1P1" (right) that appeared in 1999 is a pull open for pulling out specifications!as undoubtedly Panasonic that has led the Japanese dishwasher market.

Desktop type "NP-33S1" which was released in the same year as "NP-P45X1P1". It was developed to meet the standard from the result that it will not spread if it can not put in the sinkside of about 30 cm after thoroughly examining a Japanese house

"NP-33S1" is not only the appearance, but the basket to set the dishes is also a design close to the recent Panasonic desktop type

 

Dishwashers, for which the basic structure has been established to some extent, meet a variety of needs, such as large-capacity models and small pet food washing machines with a small footprint (47 x 30 cm) for small households. Products have been developed. And, basics such as "cleansing that can not be performed by hand washing" such as "stain removal mist" and "sterilization mist" including floating and removing dirt with mist containing high concentration detergent solution generated by ultrasonic waves, improvement of water saving performance We have continued to refine our performance and have reached the current production total of 10 million units.

What is the attraction of a dishwasher?

Panasonic's latest model, which has developed and manufactured a dishwasher for nearly 60 years, has built-in type, desktop type and some lineups, but this time picks up the top model "NP-TR9" of desktop type We check how much it has evolved and explain the attractiveness of the dishwasher. The size of the dish washer / drier “NP-TR9” released in July 2016 is 550 (width) x 564 (height) x 347 (depth) mm. Although it is the capacity that 45 points of dishes enter, because the depth is relatively suppressed, it is an impression that it is easy to secure the cooking space

 

Dishwasher can be "selected" dishwashing, so the burden of housework is of course reduced, but it also has high water saving performance, and it is a great attraction that it leads to savings in water bills. For example, when washing dishes equivalent to 6 servings (45 dishes and 24 small items) with NP-TR9, about 84 liters of water is used for hand washing, but about 11 liters for dish washers. Unlike handwashing where the water is drained, the dishwasher is a circulating formula that stores and cleans, so less water is needed. So why can a dishwasher be cleaned with less water? The secret lies in the water temperature, detergent and water flow. Oil stains that are hard to fall off too hard are far beyond the temperature range around 50 ° C where pig and cow fat dissolves

If the product is washed at a high temperature of 60 to 80 ° C, it can be easily removed (in hand washing it is difficult to remove oil because it is washed with 20 to 30 ° C hot water). Furthermore, detergents for dishwashers are highly concentrated, containing enzymes and bleaching ingredients that are not included in kitchen detergents. Enzymes break down proteins and starches such as eggs and rice grains, and bleach components break down the attached astringent tea and also have a disinfectant effect.

 

Kitchen cleaners that do not contain bleach or enzymes must be scrubbed and cleaned with your hands. On the other hand, since the detergent for dishwashers contains an ingredient that decomposes and removes the dirt, it seems that it is easy to remove the dirt that had been difficult in hand washing

 

I compared the difference in the decomposition power of the kitchen detergent used in hand washing and the dishwashing detergent (see the video below). Put each detergent in a container with rice porridge and shake it for dozens of times! Kitchen detergents did not change in a state where detergent was mixed with thick rice porridge, but rice porridge with dishwashing detergent has lost its viscosity and has become smooth. This is because the enzyme degraded starch. In other words, if it is a dish washer / drier that uses a special detergent, it is possible to make it easy to drop the dried and stuck rice iThese, in addition to the effect of water temperature and detergent, a powerful stream of water flushes out dirt. I can not see the water flow in operation, but if there is no lid, the water flow spouted from the nozzle seems to be as high as 2 m in height. Furthermore, the rotating nozzle can diffuse the water flow over a wide area.n the bowl. Equipped with nozzles facing in various directions. The nozzle in the upper right and back sprays water and detergent solution upward while rotating the three boomerang-like nozzles forward.

 

Please check the water flow in the video below. The video has a 2015 release model "NP-TR8", but the mechanism of injection is the same. As water is jetted strongly, potato which clogged in colander's eyes cleans up by washing of dishwasher!

 

Despite storing and washing the water, the dish washer / drier uses a heater, so it costs extra electricity. You might think, but running costs such as water charges, electricity charges (gas charges in hand washing), detergents are less expensive than hand washing. The difference is about 35 yen per time. There is a slight difference, but if you do dishwashing twice a day, it will save about 25,000 yen in one year if you introduce NP-TR9.

The features and functions added to the latest model "NP-TR9" are good!

The water flow introduced so far is common to the conventional table-top dishwasher and dryer, but the latest model “NP-TR9” has a new mechanism to improve usability and a powerful cleaning course. First, let's look at the newly adopted mechanism. NP-TR9 is able to put some dishes in the basket easily by moving part of the baskets that line the dishes. It's important to keep the water flow firmly on the dishes, so being able to set the dishes properly should lead to better cleaning.

A part of the lower basket has become a collapsible specification

It is an area where flat plates were arranged until now, but you can fold it and set it with a bowl and bowl set.

 

Next, we will introduce the newly added wash course "Powerful course". The "standard course" is operated by a 7 minute pre-washing process → washing with a water temperature of about 52 ° C → rinsing → heat rinsing at about 70 ° C → drying, but the powerful course is about 40 ° C at the beginning of the washing process. Activate the enzyme in the detergent with water temperature and then wash with water temperature over 70 ° C. After that, rinse with water at 60 ° C, heat rinse at about 70 ° C and dry it. By taking more time to wash than the standard course, it is possible to clear the fish grill grill gitgitto oil. I have tried the "standard course" of the conventional model, but even in the standard course, the plate with curry paste, the bowl with meat fat, and the rice with stiffness were dropped well. It has been a particularly unsatisfying cleaning power, but I think it's quite attractive that fish grills can be beautifully done with "on leave".It is an area where flat plates were arranged until now, but you can fold it and set it with a bowl and bowl set.

Even if the plate with curry paste, the bowl with meat fat, and the rice with stiffness were dropped well. It has been a particularly uncleansing cleaning power, but I think it's quite attractive "on leave".Grilled dishes after grilled fish is also beautiful in the powerful course! The skin of the sticking fish was also washed off properly

Water the grill pan and check for any oil left! As a result, the oil did not float at all, and it was confirmed that the oil was firmly removed

 

<Related article> The cleaning power of the standard course is checked by the review of the conventional model!

In fact, I have visited the factory!

By the way, where did you shoot, such as the actual dishwasher, which feels the history mentioned at the beginning? Some people are worried about it. In fact, we have visited the Kusatsu Plant in Shiga Prefecture on a press tour held to commemorate the cumulative production of 10 million units of dishwashers. The Kusatsu Plant in Shiga Prefecture manufactures 330,000 built-in type dishwashers annually, and we received lectures on efficiency of operations and measures for safety, etc. As evolution was interesting, we introduced from the first machine to the latest model this time. If you look now, the form of the old dishwasher seems pretty, but there is no doubt that the washing power was not good either structurally (lol).

I have reviewed a tabletop dishwasher approximately six years ago, but at that time, there was a part that I thought "clean?" The rice attached to the bowl was not slightly dropped. As a result, I thought that the washing power of the dishwasher was not good enough, but I was surprised using the desktop type "NP-TR8" in 2015! It's so dirty that it falls. Oil stains and worrying rice cakes were cleaned in one operation. It has evolved so much in just a few years, so if you're dissatisfied with dirt a few years ago, you might want to consider replacing it.

Kusatsu Plant in Shiga Prefecture, which has an area equivalent to 11 Tokyo Domes

 

Refrigerator History

Refrigerator History [History of Refrigerators in the World / Japan]

History of refrigerator

How was the refrigerator that was essential to our lives born? I will briefly introduce the history.

Originally it was a tool to cool using ice

In 1803, the United States of Thomas Moore to create a "tool for refrigeration using the ice" this " refrigerator was named (refrigerator)."

Later, when the electric refrigerator is generalized, the name "refrigerator" will be inherited, leading to the present.

The refrigerator manufactured and sold by Kervineta in the United States in 1918 is said to be the prototype of a widely used household refrigerator.

Birth of domestic refrigerator No. 1 in 1930

Even in Japan, a refrigerator that uses conventional ice was common.

In 1930, Shibaura Manufacturing Co., Ltd. (now Toshiba) manufactured and sold the first domestic domestic refrigerator, SS-1200.

Standard price 720 yen. At that time, it was the price at which one small house could be built, and the purchasers were very limited, such as upper class or high-end restaurants.

From high-growth era dream products to household necessities

In the late 1950s, the spread to general homes progressed rapidly and, together with black-and-white TVs and washing machines, it was called "three kinds of jinki" and became popular.

In the 1960s, frozen foods were actively developed, and refrigerators with freezers were put on the market according to demand. In 1969, a two-door type in which a refrigerator and a freezer were separated appeared, and this type can be seen even now.

In 1973, a three-door refrigerator with a separate vegetable storage room was launched. In addition, the fourth Middle East War broke out in the same year. "Energy saving", which manufacturers recommend energy saving due to the oil crisis, is also attracting attention from around this time.

In 1975, the penetration rate of refrigerators became almost 100%, and one era has reached the age of one.

1. History of refrigeration

In the beginning

We routinely receive the benefits of "cooling" and "freezing". For example, air conditioners for cool and comfortable summer use, ice cream from the refrigerator for snacks, plus frozen food for lunch side dishes. All of these became familiar as refrigerators were generally used. So what did you do before the refrigerator was made? 
Let's understand the history of cooling and freezing here.

Utilization of natural ice in ancient times

The history of refrigeration in the countries of the world including Japan begins with the use of natural ice and snow. If I wanted to warm in the cold season, I could warm up with fire, but getting cool in the hot season was very difficult. Therefore, the ancient people treated snow and ice carefully as a gift from the sky, and used it in a useful way. The oldest literature on the use of natural ice in Japan is considered the Nihon Shoki. When people in the palace hunted in Yamatoku (now Nara Prefecture) in Ninde 62 (about AD 300), I found that there were caves that I was interested in at the foot of the mountain. When I asked the strong man in the area, I found it to be an ice chamber (hymro) that stores ice collected in winter. It is recorded that the ice was brought back and presented to Emperor Nitoku.

Since that time, the place has been storing ice in the ice chamber every year around December and has been used for the court from April to September. Furthermore, June 1 was designated as a day of ice dedication, and I called a Bungu 100 official in charge of the ice. This is considered to be the beginning of the “Guiseki no Uta”. Even today, for people related to the ice making business, June 1 is a special anniversary, and events are held all over Japan.

 

Natural ice in the early Meiji period

After that, although there was a record that Kaga-an was iced to the Shogunate in the Edo period, the use of ice was only about to be carried out. After that, natural ice became common around 1870 after the Meiji Restoration.

Nakagawa Kachibei, who lives in Yokohama, operates a beef merchant for foreigners in the settlement and has also been visiting foreign diplomatic offices in Tokyo. When transportation was inconvenient, it was not easy to transport meat from Yokohama to Tokyo, and sometimes it even damaged the meat. The idea of ​​using natural ice to solve this is said to be the beginning of the natural ice business.

Nakagawa made an ice storage in Motomachi, Yokohama in 1864, and searched for good quality ice from Kanto area to Tohoku area, and after 18 years, it was finally able to demand a large amount of good quality ice from Hakodate Goryokaku. The ice produced in the cold land is very hard ice quality, and later it will be a major force as Hakodate ice. 
Stimulated by the success of Hakodate ice, ice harvesters will increase in the Kanto area and Kansai area, and we will enter the heyday of natural ice. It was mainly used for such purpose of carrying while keeping freshness of meat and fish. The third method of storing food by methods other than dried fish (dried) and salted (salted) was storage with natural ice.

From natural ice to the age of refrigerator

Around 1873, when the natural ice business began in Japan, Professor Linde of the Munich Technical School in Germany, along with a beer brewer, promoted the development of freezers and commercialized them. At that time, European beer at the time had high fermentation temperature, that is, top-fermented beer that could be brewed without freezing technology was mainstream. However, the lager-type beer with a refreshing drink, which has a low fermentation temperature called bottom fermentation. There was a need to manufacture this throughout the year, but at that time it was only possible to brew in cold weather. It was a refrigerator that was born to solve it.

It was difficult to say that the “vapor compression type refrigeration cycle” type refrigerator that has been most commonly used for home air conditioners, refrigerators, and food factory refrigerators has been developed. Linde's development is an "ammonia-type refrigerator" that uses ammonia as the "refrigerant", and the basic principle is still used today.

If the comfortable life of the modern society is based on the original, "I want to drink a good beer!" It was an innovation that was born from such needs.

Let's explore the mechanism of cooling and freezing and the mechanism of the refrigerator.

How to wash the tank with baking soda

In the vertical type, fill the tank with water at 40 to 45 ° C enough to prevent spilling, and add a cup of baking soda.

Operate for about 5 minutes by "washing". If left as it is for half a day to overnight, dirt and black mold will float.

Remove any dirt that has floated, wash again for about 5 minutes, and drain. Then repeat the rinse and spin several times.

A washing machine that is essential for daily laundry. In order to keep it clean as long as possible, the washing machine needs to be cleaned. However, there are many people who do not know the correct maintenance method and the items to be used for cleaning ... unexpectedly? Therefore, with the cooperation of the home appliance maker "Haier", we will explain the basics of cleaning the washing machine!

What should I do to clean the washing machine?

If you use the washing machine on a daily basis, dirt will gradually accumulate. No matter how much you wash with a dirty washing machine, of course your clothes won't be beautiful.

 

It is easy to collect dirt inside the washing machine, such as detergent input cases, dust removal nets and drainage filters. These parts need to be removed and cleaned according to the instruction manual of the washing machine. Let's remove the dust accumulated on the uneven part of the operation panel and the lid outside the main body.

 

And it's important to wash the laundry tub where there are invisible bacteria and mold. Don't forget to take care of your laundry, as it may cause dark waste on your laundry when cleaning up the laundry tub.

Check how to clean your washing machine now!

Parts to be cleaned with a washing machine

In order to do a clean laundry, you need to clean the following parts of the washing machine.

 

Detergent dosing case

Garbage net

Drainage filter

Laundry tub

control panel

lid

Outside of the washing machine body

We will introduce you how to care for each.

 

Detergent input case, waste removal net, drainage filter

Remove the detergent case and wash it with water. There are many cases where soap scum is attached, so let's scrape it with a toothbrush. With the case removed, remove the dirt from the mouth and wipe with a squeezed cloth.

Left: Before → Right: After

 

Left: Before → Right: After

In the case of a drum type, remove the drainage filter and remove dust. As residual water may flow out, remove the container which receives the water under the condition of 下.

 

We turn over garbage collection net and lint filter (in the case of vertical type) and scrape out garbage and wash in water.

 

Operation panel, lid part, other than the main body

(※ Note) Unplug the power plug from the outlet, and work with the faucet closed.

 

Wipe the outside of the main unit and the control panel with a soft squeezed soft cloth. If you can not get dirty, wipe with a diluted household synthetic detergent and then wipe with water → dry.

Dust that has accumulated in the convex and concave portions of the lid is wiped off with a vacuum cleaner and then using a squeezed cloth. The back of the lid is also dirty than expected. In particular, detergent and dirt are likely to collect in the packing, so wipe with a cloth or scrub with a toothbrush.

 

Check the waste accumulated in the water supply port. If you leave it as it is, it will be a factor that the way of water gets worse. Remove the water supply hose once to remove dust. It is easy to remove it by holding it with a towel and rotating it slowly so that the water remaining in the hose does not splash.

Laundry tub

Take care once in 2 months using a commercially available chlorine bleach or laundry tub cleaner! If using powder soap, once a month is a guideline.

 

If there is a "tank washing course" in the model used, store the hot water at a temperature slightly higher than the 40-45 ° C bath in the washing tank, and start operation after adding chlorine bleach and washing tank cleaner. It becomes easy to fall off the detergent dust which is stuck.

 

If there is no tank cleaning course, fill the tank if it's vertical, or if it's a drum type, it's enough to prevent spills. Put chlorine bleach and "wash" operation and leave for 2 to 3 hours. After that, repeat "washing" only 3 times and finally drive on the "standard" course

Why is it good to use chlorine bleach?

There are two types of bleaches: enzyme and chlorine, and the enzyme removes strong stains by the strong foaming action of sodium percarbonate. Chlorine, on the other hand, is mainly composed of sodium hypochlorite and has a very strong bactericidal action. If you wash the tank frequently, it is OK even with the enzyme system, but chlorine is effective for measures against mold and odor in the tank.

Environmentally Friendly! Recommended washing tank cleaner

Various washing tank cleaners are commercially available, but we will introduce some of them that contain environmentally friendly ingredients.

How to clean the washing machine using environmentally friendly items

We will also show you how to clean your washing machine using items of natural origin such as "baking soda" and "citric acid". It is a nice point that the handling is safe and environmentally friendly.

 

Baking soda works on "oil stains" and "black mold"!

Baking soda is effective against mild alkaline stains such as hand-cage and oil stains. Apply a small amount of water to the cloth and wipe the outside of the body or the lid to make it shiny. It can also be used in place of a laundry tub cleaner.

 

 

How to wash the tank with baking soda

In the vertical type, fill the tank with water at 40 to 45 ° C enough to prevent spilling, and add a cup of baking soda.

Operate for about 5 minutes by "washing". If left as it is for half a day to overnight, dirt and black mold will float.

Remove any dirt that has floated, wash again for about 5 minutes, and drain. Then repeat the rinse and spin several times.

Citric acid works well for soap scum and sterilization.

Citric acid is effective in removing weak acid stains such as soap scum and hot red water. In addition, we can expect reduction of ammonia smell and bacteriostatic effect

 

 

How to wash the tank with citric acid + enzyme bleach

In the vertical type, the tank is full, and the drum type is filled with 50 ° C hot water to the extent that it does not spill, and put the specified amount of oxygen bleach. (※ Enzyme-based bleach is used to prevent the generation of non-null stains that can be generated by combining soap and citric acid)

Allow to drain for a while, add water again and add 1 cup of citric acid.

Operate for about 3 minutes by "washing". Leave for half a day to overnight.

Repeat rinsing and dewatering several times.

Summary

If the washing machine is not well-maintained, it will not only cause bacteria to get on the clothes, but it may also increase the operation time and cause poor drying. Please refer to the cleaning method introduced this time, and give care to your regular workers, with the intention of enforcing the washing machine of the worker.

Do you know the history of vacuum cleaners that have existed for over 100 years?

Do you know the history of vacuum cleaners that have existed for over 100 years?

This is a proof of history.

The incident only a few hours ago, from that point I just liked cleaning a little bit. It's still hard to believe, but I encountered a strange event and got to know the history of the vacuum cleaner. The rainy season, which is a distraction, has finally opened. However, I still felt that the long-lasting, moist daily image had not yet passed away, and I could not get a proper feel no matter what I did. It would be better if it was clean at least in the room alone ... I turned on the power with the stick-type vacuum cleaner in my living room, "Elgorapide Lithium".Well, let's start cleaning ....

 

Switch on your hand so that you can pull your mind and body up. Oh, but the latest vacuum cleaner is excellent.

 

I'm going without hesitation, I'm going to swipe, because it's a rechargeable cordless, I don't need to boIsn't it possible that the concept that can be cleaned immediately is a great solution?

 

However, the vacuum cleaner has also evolved. When I was small, I felt it wasn't in such a convenient form, and I have more stupid memories. No, wait a minute?

 

I "If it said so, would it have been from the vacuum cleaner?"

 

I had such a question, then ... a strange thing happened!

 

--- ... ... my husband.ther with troublesome cords. Also, it's great that I don't want to go wild in appearance. Soon to handErgoraped Lithium in front of us was talking. And fluent Japanese .... What's going on Oh my God!

 

-The master is interested in the history of vacuum cleaners. Please leave it to me. Even if it looks like this, I have a history of 100 years to this figure. OK, let's calm down. A vacuum cleaner speaks. ... OK, let's give it 100 steps. Although I was called a husband, I bought it because I was not wrong with the master-slave relationship. However, I was interested in the content rather than the tone. Does this vacuum cleaner have such a deep history?

 

I "Oh, that .... Is 100 years really serious?" -Do you have any doubts about your husband? It is ok ....

――Please take a look at the 100-year history of the Electrolux vacuum cleaner that created me! History of vacuum cleaners taught by Ergorapid-It was about 1912 when the Titanic sank. Electrolux launched the world's first household model vacuum cleaner "LUX1". The previous vacuum was 20 kg, almost like a stationary, but LUX 1 weighs 14 kg. I managed to carry it and move it. I "No, 14 kg is quite heavy! I can not move it with me, but .... But, well, the types of nozzles have been abundant since this time"--- Rest assured. A big leap will come soon. The "Model V" that appeared in 1921 can be dragged and moved by metal legs like rails. It is the world's first mobile vacuum cleaner! It is also possible to put on a shoulder or hand, so that anyone can clean it easily.

 

I "I see, the poster is a little too exaggerated, but it may be a good expression that is likely to lighten up. If you replace it with the present, the magical girl-like image of taking a vacuum cleaner instead of a broom?"

 

--- I do not understand magic girls at all, but this model V has a little anecdotes. In Sweden, which was a culture of housekeepers at the time, when housekeepers became unemployed, even demonstrations occurred. I "... Sweden is great ..." I "Oh, this photo is pretty close to a modern vacuum cleaner. It has wheels and cords are also retractable."

 

――Exactly (as it is). This "Luxomatic Z90" is a model that becomes the prototype of the modern vacuum cleaner, and appeared in 1964. You can move freely anywhere with wheels, equipped with an automatic sealed dust pack, and there is also a function to notify you by an indicator when the dust pack is full. It is natural now, but at that time it contained innovative ideas.

 

I "Hm .... If you are told it is definitely an improvement for the home. From the point of view of the person who cleans up every day, they are chasing the function," A vacuum cleaner is useful if this "

And vacuum cleaner is stick type. What was that reason that led to the present form?

I, "by the way, Mr. Ergorou. I feel that it's still far from your shape, but how many years ago became vertical?"

 

--- I can not give strange nicknames, but let me answer. Vacuum cleaners have shown various developments such as miniaturization and noise reduction, but it was in 2004 that “ergolapide 2 in 1”, the first of the so-called cordless stick type “ergorapide” series, appeared . Its design and functionality have a great impact on the market and has won numerous awards. I'm sure it would be amazing to get to this form more than 10 years ago now ... I think it's good as a sleek design, and good for women Uke. By the way, have you been independent since then?

 

--- Good question. Please look at this image. This is a comparison between Ergorapide's second-generation model and its latest model, Ergorapide Lithium. Left: Ergorapid lithium Right: Second-generation Ergoraped

I "Oh, do you stand ...?"

 

--- No, I'm not standing. There was no self-supporting mechanism at this time, and I would fall down if I did not reach my hand. It was a style that stood on the wall.

 

I "I see, if you look at it, it looks like the design but it has been improved. What else has changed?"

 

-There are numerous minor changes. When I will explain where it is my recommended point ......

Left: Ergorapid lithium Right: Second-generation Ergoraped

-The head is bent to an angle close to 90 degrees. It moves with the movement of the hand, so it can be cleaned with minimal force. Also, the weight of the latest model is only 500 grams at the time of operation. It is popular that even women can clean without burden. ――The head has also been improved year by year, and now it has such shape. The metal frame is a guard to prevent the entrainment such as pencils. The processing of the mountain shape ahead is "triangle power nozzle". Rather than just a design, this shape increases the flow of air and improves the efficiency of suction.

-Please let us boast the features that are unique to Ergoraped in recent years. This "PRESS" button is an original technology "brush roll clean function". Just press the switch to cut and suck the hair and other debris to the head brush.

 

I "This PRESS mark had such a meaning. Only the owner did not know ..."

--- In addition, the third generation has become able to operate the removal button with one hand, equipped with 6 types of nozzles including a futon nozzle, can store the brush nozzle in the station or the main body, and a dark gap However, even if there is no change in the form of a stick type, such as mounting an LED light that is easy to clean, it has been updated more convenient and easier to use each time the model is updated.

 

I "I'm really interested in it. Especially the brush nozzle storage. But I think that there was a demand for" It would be useful if I could take it out immediately. "Certainly this would be inconvenient."

 

--That's right. For 100 years, based on the position of a user, Electrolux has been pursuing ease of use, that is, "How to comfortably change the pain of cleaning?" To that end, I have considered lowering the center of gravity, making it easy for removal, just like small turns, listening to the battery so as to hold it in a comfortable way, and above all, sucking up a lot of trash. --- A compilation of 100 years that faces cleaning. That's the way I am now. Could you understand?

 

I "Well, I see, I understand. By the way, how long now?"

 

-It's only about 20 minutes. My ergolapide lithium ZB3114AK uses a turbo-power lithium-ion battery and can operate for about 45 minutes on a full charge, so I can talk about another 25 minutes! Now how about your husband and then a haunting Swedish joke ...

 

(Pochi ... T)

 

I gently pressed the power button.

 

The rest of the battery is 25 minutes. If it is only that, you will come fishing even if you clean the house. I put my head on the floor again, and after a big deep breath I turned on a dreadful power.

 

Wy wyin ....

The vacuum cleaner starts to move with the same suction noise as usual. Even if I hit it a little, there is no response. It was back to a regular vacuum cleaner that did not talk or start moving freely.

After all that is a dream. Perhaps it was a passionate day dream ....

 

However, it is an interesting content for history lovers and household appliances lovers. I'm interested in the indifferent “vacuum cleaner” thanks to this mysterious experience. And if I thought that history and technology were full, I would like a bit of cleaning that was only troublesome ...

 

Wii Yin ...!

 

I felt that the voice of the vacuum cleaner grew louder. Did you convey my feelings? ... what But let's do that. 100 years of history, welcome to my home.

Let's continue cleaning!

History of refrigerator

History of refrigerator

How was the refrigerator that was essential to our lives born? I will briefly introduce the history.

 

Originally it was a tool to cool using ice

In 1803, Thomas Moore of the United States created "a tool for refrigeration using ice" and named it "refrigerator".

 

Later, when the electric refrigerator is generalized, the name "refrigerator" will be inherited, leading to the present.

 

The refrigerator manufactured and sold by Kervineta in the United States in 1918 is said to be the prototype of a widely used household refrigerator.

 

 

The refrigerator manufactured and sold by Kervineta in the United States in 1918 is said to be the prototype oBirth of domestic refrigerator No. 1 in 1930

Even in Japan, a refrigerator that uses conventional ice was common.

 

In 1930, Shibaura Manufacturing Co., Ltd. (now Toshiba) manufactured and sold the first domestic domestic refrigerator, SS-1200.

 

Standard price 720 yen. At that time, it was the price that one small house could be built, and the purchasers were very limited, such as upper class or luxury restaurants.

From high-growth era dream products to household necessities

In the late 1950s, the spread to general homes progressed rapidly and, together with black-and-white TVs and washing machines, it was called "three kinds of jinki" and became popular.

 

 

 

In the 1960s, frozen foods were actively developed, and refrigerators with freezers were put on the market according to demand. In 1969, a two-door type in which a refrigerator and a freezer were separated appeared, and this type can be seen even now.

 

In 1973, a three-door refrigerator with a separate vegetable storage room was launched. In addition, the fourth Middle East War broke out in the same year. "Energy saving", which manufacturers recommend energy saving due to the oil crisis, is also attracting attention from around this time.

 

 

 

In 1975, the penetration rate of refrigerators became almost 100%, and one era has reached the age of one.

Open the household electric refrigerator

A refrigerator (English: Refrigerator) [1] is a product intended to store articles such as food at low temperature. Nowadays, it often refers to an electric refrigerator that uses electric energy for cooling. household refrigerator.

Outline

An electric refrigerator is an electrical facility facility or an electrical product intended to store articles such as food at low temperatures. Those that use ice are sometimes called "cooler storage", "refrigerated boxes", etc.

 

In general, it is used at about 4-10 ° C. for the purpose of not freezing water at 0 ° C. or higher. What is intended to freeze at 0 ° C or lower is called a freezer, and a product that combines both functions may be called a refrigerator-freezer.

 

Refrigerator as a home appliance

As for the structure, a refrigerator, which is a type of heat pump, is basically attached to a box that holds the contents, and the heat in the storage is dissipated to the outside, and a heat insulating material is used for the wall separating the interior and the exterior. It is blocking movement. A door is also provided for loading and unloading articles. In addition, in order to make the contents easy to see, a mode in which illumination is provided inside is also common.

 

As a result, the refrigerator cools the inside of the refrigerator,

As for the structure, a refrigerator, which is a type of heat pump, is basically attached to a box that holds the contents, and the heat in the storage is dissipated to the outside, and a heat insulating material is used for the wall separating the interior and the exterior. It is blocking movement. A door is also provided for loading and unloading articles. In addition, in order to make the contents easy to see, a mode in which illumination is provided inside is also common.

 

As a result of cooling the inside of the refrigerator, the moisture in the air inside the refrigerator condenses on the cooled portion, resulting in frost. Since the frost is periodically melted and discharged to the outside of the storage room, the humidity in the storage decreases and it dries. When sashimi or meat is stored, a wrap film is used so as not to dry. In order to suppress the decrease in humidity, the vegetable room for containing vegetables whose dried state is not desirable is configured to be indirectly cooled from the outside of the cabinet. In large kitchens and the like for business use, a constant temperature and high humidity storage may be set in a low temperature state instead of a normal refrigerator in order to prevent the food from being dried.

 

The smell of raw materials etc.

For household use, one that has a refrigerator and freezer (and related functions) integrated in an all-in-one form is the mainstream, but in the specialized fields as described later, the inside of the cabinet is set In some cases, additional functions may be provided in line with the purpose, such as a single-function product kept at a constant temperature (various ranges thereof) and a function of a showcase for displaying goods.

 

The color of the housing of the household electric refrigerator is often white, and it is also the reason why it is called "white goods". Since the 2000s, in addition to white, products of various colors have come to be marketed from the pursuit of interior character, etc., and there are also companies that apply paint to refrigerators [3].

 

Refrigerator advertisement (1926)

Refrigerator other than household appliances

In familiar examples, such as refrigerated showcases such as retailers, and a huge refrigerator or freezer that uses the entire room in the backyard, etc., in many developing countries, especially in developed countries, retail stage Refrigerators and freezers are used in various ways, including distribution and production facilities for fresh food and processed food.

 

The refrigerated car for carrying products that require cooling, such as seafood and fresh foods such as milk, has a mechanism similar to a refrigerator and has a structure that can cool the inside of the bed. In addition, courier services such as "cool flight" and "chilled flight" use a vehicle equipped with a refrigerator and a freezer inside. There is also a cooler-box-type mini-refrigerator that can be used with a DC 12V power supply for passenger cars.

Principle of cooling

Refer to "Refrigerator" for details

Two cooling methods have been used for a long time, utilizing the phenomenon that the temperature of the object is lowered by vaporization. In addition to this, in recent years, a system utilizing the Peltier effect by a semiconductor instead of vaporization has also been put to practical use and used in small applications. Evaporative compression type

 

Capacitor

Expansion valve

Evaporator

compressor

The refrigerant is circulated in a closed pipe using compression. It is called a compression type from here. For household use, it is common to use an electrically operated compressor for compression. Therefore, although there are many electric refrigerators when it comes to a refrigerator, there is also a type that uses gas pressure for compression. In addition, some have used an ejector instead of an expansion valve to increCondenser (dissipator, condenser): The refrigerant stores heat in a high pressure gas state, and returns to liquid by radiating heat. (liquid)

Expansion valve (expansion valve): A thin pipe suddenly reduces its pressure by reducing its thickness to a boiling point. (Liquid, low pressure liquid)

Evaporator (evaporator, vaporizer): A liquid whose boiling point is lowered removes the heat of vaporization from the surroundings and evaporates (vaporizes). (Cooling by vaporization: liquid turns into gas → cooling occurs) (this part is placed in the refrigerator)

Compressor (compressor): Gas.ase the efficiency (ejector cycle).

CFC was used as a refrigerant, but it has been shifted to isobutane etc. after CFC ban. However, isobutane is not a completely new refrigerant and has been used before CFC. Although CFCs were perfect for refrigerant applications, their use in consideration of environmental impact is prohibited. In recent years, ammonia, which is excellent in efficiency, has attracted attention again, but since it is dangerous if it leaks, it is equipped with a sensor, an alarm, etc. and used in a freezer warehouse etc., but it is not adopted for home use.

Vaporization absorption type

Use a liquid for the circulation of the refrigerant. The liquid moves the refrigerant by absorbing (adsorbing) the refrigerant and circulating it. This liquid is called an absorbing liquid, and hence is called an absorbing type. The fluid is circulated by heating. For this purpose, a heat source is used, and there are a gas refrigerator using a gas burner as the generator and an electric refrigerator using an electric heater. In this absorption type, a two-way type such as a gas / electric alternating current 100 V switching system and a three-way type such as a gas / electric alternating current 100 V / direct current 12 V switching system are generally used. It is superior in quietness to a compression type that requires a compressor, and is often used for medical treatment (for hospitals, etc.), hotels, and leisure because the power source does not have to be electricity.

 

The refrigerant circulates in the closed pipe.

Absorber

Generator (Regenerator, Generator, Boiler)

Separator rectification device rectifier

Condenser (dissipator condenser)

Performs evaporator cooling

In the absorber, an aqueous ammonia solution in which water absorbs ammonia is prepared. In the generator (boiler), the aqueous ammonia solution is heated. Because it has a lower boiling point than water, ammonia gasifies from the solution and forms a foam. Ammonia gas is separated from water in the separator. Water is returned to the absorber. In the radiator, ammonia that has become gas releases heat and becomes liquid. The ammonia solution whose concentration has increased in the evaporator is depressurized and vaporized. Cooling occurs. In the absorber, water absorbs the ammonia returned through another path to form an aqueous ammonia solution.

 

Sweden-based Domestic (Separate from Electrolux (2001)) is a leading manufacturer of refrigerators specializing in this type of cooling. Domestic company expresses it as absorption type and absorption system.

 

Ammonia that was once used as a refrigerant in the vaporization and compression type was anhydrous ammonia (AnhydrThe ammonia used as the refrigerant in the mold is an aqueous ammonia solution (Aqua Ammonia).

 

Stirling refrigerator

Refer to "Stirling Refrigerator" for details

A temperature difference is generated by rotating the Stirling engine with external power. It was used to cool the optical sensors of Earth Observation Satellite 1 satellite. It is also used to cool infrared imaging devices and superconducting magnets.
