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.

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.
