When the cooking cavity back plate assembly is used for heating food, heat in the heating cavity 3 can enter the cooking cavity 2 through the convection hole 10, so that the temperature of steam in the cooking cavity 2 is increased, and the food in the cooking cavity 2 is heated. In the process of heating food, steam in the cooking cavity 2 inevitably enters the heating cavity 3 through the convection hole 10, after the temperature is reduced, condensed water formed by condensing and liquefying the steam falls in the heating cavity 3, when the condensed water in the heating cavity 3 passes through the reflow hole 11, the condensed water flows back to the cooking cavity 2 through the reflow hole 11, so that the condensed water falling in the heating cavity 3 can flow back to the cooking cavity 2 through the reflow hole 11 for recycling or be cleaned, at the moment, the condensed water is not easy to accumulate in the heating cavity 3, peculiar smell generated by accumulating the condensed water in the heating cavity 3 for a long time can be avoided, and the use experience of a user is effectively improved.

It should be noted that, when the backflow hole 11 is disposed at the bottom side edge of the partition board 1 or near the bottom side edge of the board surface of the partition board 1, the condensed water in the heating cavity 3 is easier to overflow the backflow hole 11, and can flow back into the cooking cavity 2 through the backflow hole 11 rapidly, so as to further prevent a large amount of condensed water from accumulating in the heating cavity 3.
