The housing assembly 1 is provided with a water inlet 111 communicating with the heating chamber 101 such that water flows into the heating chamber 101 through the water inlet 111 for heating to generate water vapor. The housing assembly 1 is further provided with air outlets 112 which are in one-to-one correspondence with the pressurizing chambers 102 and are communicated with each other, so that the high-pressure steam pressurized by the pressurizing chambers 102 can flow into the inner container assembly of the dish washer through the air outlets 112.
