Example two
This example differs from the first example in that the start time of heating the washing water in the hot rinsing process is different. Specifically, as shown in fig. 2, in the present embodiment, while a preset amount of washing water is injected into an inner cavity of a dishwasher, the washing water is heated to a first preset temperature and kept at the first preset temperature for a preset holding time; after the washing water with the preset water quantity is injected into the inner cavity of the dish-washing machine, the dish-washing machine is rinsed for the preset rinsing time.
EXAMPLE III
The difference between this example and the first example is that the time for starting to supply superoxide into the dishwasher is different. Specifically, as shown in fig. 3, in this embodiment, superoxide is introduced into the water circulation channel of the dishwasher for a preset disinfection time at the same time when the dishwasher starts rinsing.
The dish washing machine is provided with the pressure relief hole for ensuring that the pressure in the inner cavity of the dish washing machine is not too high, and when the superoxide is introduced into the water circulation channel of the dish washing machine and the cleaning water is heated, the pressure in the inner cavity of the dish washing machine is increased, so that a part of the superoxide can pass through the pressure relief Kong Waixie. Because the cleaning water starts to flow through the water circulation channel when the dish-washing machine starts rinsing, the flow speed of the superoxide is improved, so that the superoxide is introduced into the water circulation channel of the dish-washing machine when the dish-washing machine starts rinsing, the preset disinfection time for introducing the superoxide can be properly reduced, and the amount of the superoxide passing through the pressure relief Kong Waixie is reduced.
In this embodiment, the preset disinfection time is less than the time taken for starting to introduce superoxide into the water circulation channel of the dishwasher until the end of rinsing. Provides enough time for the decomposition of the superoxide and reduces the residual superoxide in the dish washing machine as much as possible.

Specifically, as shown in fig. 4, in this embodiment, when the washing water is heated to the second set temperature, the superoxide is introduced into the water circulation channel of the dishwasher for a preset disinfection time.
The decomposition speed of the superoxide is improved to a certain extent along with the increase of the temperature in the inner cavity of the dish washing machine, but the decomposition half-life period of the superoxide at normal temperature and normal pressure is 16 hours, the decomposition speed is severe when the temperature exceeds 100 ℃, and the superoxide can be immediately decomposed when the temperature reaches 270 ℃. In this embodiment, the second preset temperature is less than the first preset temperature. Generally, the temperature in the inner cavity of the dishwasher reaches up to about 75 ℃, so that the first preset temperature and the second preset temperature are both less than 75 ℃. At the moment, the decomposition half-life period of the superoxide is relatively long, and the antivirus effect of using the superoxide for antivirus cannot be influenced.
Along with the increase of the temperature in the inner cavity of the dish washing machine, the air movement speed is increased, and the flow speed of the superoxide is increased, so that when the cleaning water is heated to the second set temperature, the preset disinfection time for introducing the superoxide can be properly reduced by introducing the superoxide into the water circulation channel of the dish washing machine, and the amount of the superoxide passing through the pressure relief Kong Waixie is reduced.
In this embodiment, the preset disinfection time is less than the time taken for starting to introduce superoxide into the water circulation channel of the dishwasher until the end of rinsing.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
