Exemplarily, the washing equipment can be provided with a water tank, and the municipal water can first enter the water tank. Specifically, water module 30 can be configured to pass water, or pass salt water, or pass water and salt water.

[0038] The aforementioned drying mode refers to a function of the dishwasher to dry the tableware after completing the washing program, and the storage mode refers to a function of the dishwasher to store the washed tableware after completing the washing and drying programs. In the two modes, NaClO is generated by electrolysis of the salt water by the electrolysis module 20, and the micro-bubbles enter the dishwasher, so that the washing cavity 200 can be sterilized and disinfected. In addition, after the dishwasher completes the washing program, the water cup usually contains residual water.

When the washing equipment is in drying mode or storage mode, NaClO is generated by electrolyzing salt water in electrolytic module 20, and microbubbles enter the washing equipment, which can sterilize and disinfect the washing cavity 200. In addition, after the dishwasher completes the washing program, the water cup usually contains residual water. By passing microbubble water containing NaClO into the washing cavity, the generation of odor and bacteria growth during long-term storage of tableware can be reduced.

Specifically, water can be supplied to electrolytic module 20 through water inlet component 31, and salt water can be supplied to electrolytic module 20 through salt water component 32. For example, in the washing program, water can be selected to pass to electrolytic module 20, which facilitates the generation of microbubble water by bubble generating device 100, improves the washing efficiency and washing effect of the washing equipment, and in the storage and drying program, salt water can be selected to pass to electrolytic module 20, which facilitates the generation of microbubble water containing NaClO by bubble generating device 100, and facilitates sterilization and disinfection of the washing equipment. By setting water inlet component 31, salt water component 32 and electrolytic module 20, the washing efficiency of the washing equipment is improved, and the washing equipment is sterilized and disinfected, and the function of the washing equipment is enriched.
