Furthermore, the dishwasher also comprises a cooling module, wherein the cooling module is connected with the power supply device b and is suitable for cooling the power supply device b.

In a preferred embodiment, a level sensor e is disposed in the water storage structure a1 and is capable of sending a first signal when water in the water storage structure a1 is detected to reach a predetermined level. Wherein the predetermined height is higher than the height of the water outlet a12 and lower than the height of the fluid discharge part a 5. The control module is in communication connection with the liquid level sensor e and the water inlet control element 9 and can control the water inlet control element 9 to be switched to a closed state when receiving the first signal. Although the dishwasher of the present embodiment can control the amount of water entering the water storage structure a1 by means of the flow meter 7, the level sensor e can also judge whether the water in the water storage structure a1 is suitable for preparing sterilized water, instead of the flow meter 7, when the flow meter 7 malfunctions. Therefore, the water storage structure a1 of the embodiment can overcome the defect that the dishwasher in the prior art cannot stop supplying water to the water storage structure a1 in time when the flow meter 7 fails, can avoid water flowing out from the overflow port, and reduce the risk of safety accidents caused by the water flowing out from the overflow port.

In this embodiment, the electrode holder a7 is used to fix both the discharge electrode a2 and the first insulating tube a6, so that the assembly efficiency can be further improved, and the structure of the intake passage is simple without occupying additional space.
