Why is the dishwasher so slow?

The normal washing program time range of automatic household dishwasher is 60- 120 minutes. Compared with hand washing, many people may think it takes too long to wash. But if you know the washing principle and energy consumption of the dishwasher, you won't feel that the washing time is long.

First of all, compared with hand washing, dishwasher saves water. Washing the same number of tableware, the water consumption of dishwasher is less than one third of that of hand washing. Dishwasher washing can be divided into different washing stages, generally there are at least four stages, namely: main washing, cold bleaching, hot bleaching and drying. The first three stages are water washing. Feed water once in each stage, about 3 liters, and the water used in the three stages varies from 8- 10 liters. Take the main washing as an example. After the water enters, the dishwasher will transport the water to the spray arm through the washing pump and spray it on the surface of the tableware. After falling, the water will be filtered by the filtering system, and the filtered water will enter the washing pump again and be sprayed on the surface of tableware through the spray arm. By recycling water in this way, the effect of saving water is achieved, and at the same time, water is continuously sprayed on the surface of tableware to clean the tableware. For this reason, the longer the washing time of the dishwasher, the more times the water is sprayed on the surface of the tableware, and the cleaner it is. On the other hand, if the washing time is short, the washing times will definitely be less, and the washing effect will definitely not be very good, so choosing a dishwasher and washing time is also a very important selection criterion.

Secondly, why didn't the dishwasher consume much electricity for so long? The washing pump power of the dishwasher is less than 100W, and some motors only have 50W, so the electricity consumption for continuous washing 1 0 hour will not reach1kWh. Therefore, the power consumption of the dishwasher is not large when washing. Because the dishwasher is heated and washed, the power will be higher and the power consumption will be greater only when it is heated. However, because the temperature of the dishwasher program has been set and reaches the set water temperature, the dishwasher stops heating and continues to run with a motor less than 100 watt, so the power consumption is relatively small. Generally, the normal washing process takes 60- 120 minutes, and the power consumption is 0.3-0.6 kWh, so the electricity bill varies from 10 to 30 minutes. Compared with boiling water washing, it is still very energy-saving

Although the dishwasher takes a long time to wash, it doesn't need to take out the tableware after washing, so it won't take up our time. This is a very good experience.

At present, there are more and more companies making dishwashers in China, so it is recommended to choose a Chinese dishwasher with moderate washing time. Procedures such as imported dishwashers will not last more than three hours, and it will not be said that the cleaning effect will be abandoned in order to cater to a short time. Generally speaking, dishwashers are more suitable for 60-90 minutes.
