[0002] With the development of the economy and the continuous improvement of living standards, people are increasingly pursuing a free life of higher quality. As a product that can free your hands, dishwashers are being favored by more and more families. Existing dishwashers have proposed a new method for washing and disinfecting dishes. This disinfection method is a liquid plasma disinfection technology. Its principle is to use high-voltage discharge to generate plasma in a liquid environment. During the discharge, high-energy electrons around the gas / liquid interface react violently with air and water molecules to generate strong oxidizing substances such as OH· and H2O2, producing a solution with the ability to disinfect bacteria and viruses, referred to as disinfectant. Ozone is produced in the process of the disinfectant entering the inner tank to wash and disinfect tableware. Since ozone is not easily soluble in water and the inner tank is a non-enclosed space, ozone is easily emitted into the air during use. Long-term use will have adverse effects on human health.

It is understandable that the temperature sensor and the turbidity sensor can detect the temperature and turbidity of the water and the disinfectant, and the filter assembly is composed of a coarse filter, a fine filter, and a microfilter, which is used to filter the residue to prevent the residue from entering and mixing into the washing. It should also be noted that a water level pressure switch can also be installed on the water cup 112 to detect the water level in the water cup 112.

[0038] See also Figure 3 , Figure 3 1 is a flow chart of a method for controlling a dishwasher provided by an embodiment of the present invention. The method for controlling a dishwasher is applied to the above-mentioned dishwasher, and the method for controlling the dishwasher is described in detail below. Figure 3 As shown, the method includes the following steps S110-S140.

[0039] S110, if a disinfection command is received, controlling the water pump to inject the disinfectant in the disinfectant manufacturing device into the water cup;

[0040] S120, controlling the washing pump to deliver the disinfectant in the water cup to the spray arm to disinfect the tableware placed in the bowl basket in the inner tank;

[0041] S130, if a washing completion instruction is received, controlling the drain pump to drain water, and controlling the first fan, the second fan and the ozone elimination element to operate;

[0042] S140, determining whether disinfection is completed based on the ozone concentration in the inner container detected by the ozone detection element.

[0043] In this embodiment, after receiving the disinfection command, the dishwasher controls the water pump to inject the disinfectant in the disinfectant manufacturing device into the water cup, and controls the washing pump to transport the disinfectant in the water cup to the spray arm, and the spray arm sprays the disinfectant through the spray hole to disinfect the tableware placed in the bowl basket in the inner tank. After disinfection, if the dishwasher receives a washing completion instruction, it controls the drainage pump to drain the water, and controls the first fan, the second fan and the ozone elimination component to operate so that the air inside the dishwasher is exchanged with the outside air. The air inside the dishwasher passes through the ozone elimination component and becomes air without harmful gases, thereby achieving the purpose of preventing ozone leakage. The inner tank is provided with the ozone detection component, and the ozone concentration in the inner tank is detected in real time by the ozone detection component, and whether the disinfection is completed is determined according to the ozone concentration.

[0044] In some embodiments, such as the present embodiment, Figure 4 As shown, the step S140 may include steps S141-S144.

[0045] S141, obtaining the ozone concentration in the inner tank detected by the ozone detection element;

[0046] S142, determining whether the ozone concentration is less than a preset ozone concentration safety threshold, if the ozone concentration is less than the preset ozone concentration safety threshold, executing step S143; otherwise, executing step S144;

[0047] S143, prompting that disinfection is complete and the machine door can be opened;

[0048] S144, returning to the step of controlling the first fan, the second fan and the ozone elimination component, and prompting that the disinfection is not completed and the machine door cannot be opened.

[0049] In this embodiment, the ozone concentration in the inner tank detected by the ozone detection element is obtained;

[0050] Determine whether the ozone concentration is less than a preset ozone concentration safety threshold; if the ozone concentration is less than the preset ozone concentration safety threshold, indicating that the ozone concentration is not high and will not affect human health, then it is prompted that the disinfection is completed and the door can be opened, and the ozone elimination logic is stopped, that is, the control of the first fan, the second fan and the ozone elimination component is stopped, that is, the first fan, the second fan and the ozone elimination component are controlled to stop working; if the ozone concentration is not less than the preset ozone concentration safety threshold, indicating that the ozone concentration is still very high and will affect human health, then return to the step of controlling the first fan, the second fan and the ozone elimination component, and prompt that the disinfection is not completed and the door cannot be opened to avoid ozone leakage and endangering human health.

[0051] Figure 5 A flow chart of a method for controlling a dishwasher according to another embodiment of the present invention is shown in FIG. Figure 5 As shown, in this embodiment, the method includes steps S110-S160. That is, in this embodiment, before step S110 of the above embodiment, the method further includes steps S150 and S160.

[0052] S150, if a disinfectant manufacturing command is received, controlling the three-way valve to inject water into the disinfectant manufacturing device, and measuring the amount of injected water by a flow meter;

[0053] S160. When the water volume reaches a preset water inlet volume, the three-way valve is controlled to be blocked, and the disinfectant manufacturing device is controlled to discharge high voltage to manufacture the disinfectant.

[0054] In this embodiment, if the dishwasher receives a command to produce disinfectant, the three-way valve is controlled to inject water into the disinfectant manufacturing device, and the amount of water injected is measured by a flow meter. When the amount of water reaches a preset water inlet, the three-way valve is controlled to be blocked, and the disinfectant manufacturing device is controlled to discharge high voltage to produce the disinfectant. It is understandable that the preset water inlet is set according to actual needs and is not specifically limited here. It should be noted that in this embodiment, after the dishwasher receives the disinfection command, the manufactured disinfectant is pumped into the inner tank by a water pump. It is understandable that when the dishwasher receives the disinfection command, it indicates that disinfectant is needed at this time.

[0055] It should also be noted that, in this embodiment, if the dishwasher receives a wash command, the three-way valve is controlled to inject water into the water cup, and the amount of water injected is measured by the flow meter. When the amount of water reaches the preset water cup inflow amount, the three-way valve is controlled to be blocked, and the washing pump is controlled to transport the water in the water cup to the spray arm to wash the tableware placed in the bowl basket in the inner tank. It can be understood that when the amount of water does not reach the preset water cup inflow amount, the three-way valve is continued to be controlled to be turned on to continue injecting water into the water cup.

[0056] To summarize, in this embodiment, the ozone elimination component is used to eliminate the residual ozone when the tableware placed in the bowl basket in the inner tank is disinfected; the ozone detection component is used to detect the ozone concentration in the inner tank in real time to indicate whether the machine door can be opened; the one-way valve is used to control the outside air to enter the inner tank. During the entire dishwasher disinfection process, the leakage of harmful gases is effectively avoided, which is beneficial to human health.
