The continued operation of the pump body generates negative pressure in the water outlet pipe, which forces the gap on the one-way valve to open, so that the condensed water in the water storage tank passes through the one-way valve and the water outlet pipe into the second water inlet pipe, thereby realizing the supply of condensed water in the water storage tank. When the water supply of the water storage tank reaches the set time, the control circuit board controls the first solenoid valve to operate, so that the first inlet and outlet are unblocked, and the second inlet and outlet are closed, and water is supplied through the water storage unit again. The water storage unit and the water storage tank supply water alternately in turn until the high-temperature cooking mode ends. BRIEF DESCRIPTION OF THE DRAWINGS
