When the cover assembly 200 is in the closed state, the cover plate 2 and the thermal insulation plate 12 are horizontally disposed, since the cover plate 2 is located inside the thermal insulation plate 12 (for example, the lower side shown in FIG. 4), thereby being generated in the cooking cavity 1001. When the steam moves upward, the cover 2 can be first contacted, so that the cover 2 can be easily removed and cleaned by the user by detachably attaching the cover 2 to the cover 1 or the thermal insulation board 12. Among them, the snap structure is well known to those skilled in the art and will not be described in detail herein. In addition, the cover 2 can also be connected to the cover 1 or the thermal insulation board 12 by other means. Here, it should be noted that "inner" can be understood as a direction toward the center of the cooking chamber 1001, and an opposite direction is defined as "outer", that is, a direction away from the center of the cooking chamber 1001.

Further, the sealing assembly 3 is disposed between the thermal insulation board 12 and the cover plate 2 to define the accommodating cavity 201 together with the thermal insulation board 12 and the cover plate 2.
