Specifically, the gas passage is in communication with the environment, and the gas passage is in communication with the first chamber 106 or the second chamber 108. When the gas channel is in a conducting state, one end of the gas channel is communicated with the external atmosphere, and the other end of the gas channel is communicated with the first chamber 106 or the second chamber 108 and the environment, that is, the first chamber 106 and the second chamber 108 are both directly communicated with the external environment, so that the pressure values in the first chamber 106 and the second chamber 108 are the same as the external environment, the pressure difference between the first chamber 106 and the second chamber 108 is reduced, and the washing of the food to be cooked 200 is finished.

Example four:
