As shown in fig. 1, 4 and 5, the detachable cover 30 is provided with a detachable cover access hole 39 corresponding to the cooking cavity access hole 29. The removable cover air inlet and outlet hole 39 communicates with the cooking cavity air inlet and outlet hole 29, so that the air flow generating device communicates with the cooking space 54 through the cooking cavity air inlet and outlet hole 29 and the removable cover air inlet and outlet hole 39. The air flow generating means is configured as an air pump, for example, so that the air pump can suck air from the cooking space 54 from the detachable cover air inlet and outlet hole 39 or feed air to the cooking space 54. When the cooking chamber communication hole 33 is blocked, it is possible to achieve an air pressure in the cooking space 54 higher or lower than the ambient air pressure. When the cooking cavity communication hole 33 is opened, ambient air (cool air) may be introduced into the cooking space 54 to cool the cooking space 54.

In the illustrated embodiment, a removable cover is provided on the underside of the liner cover body 21, as shown in fig. 4, for example. The cap assembly 10 further includes a first sealing device 24. The first sealing means 24 is connected to the body portion 25 and/or the cavity portion 26 and surrounds the periphery of the cavity portion 26. When the removable cover 30 is mounted to the liner cover 20, the removable cover 30 contacts the first sealing device. In the projection in the up-down direction DH of the cap assembly 10, the region of the detachable cap 30 surrounded by the first sealing means is a corresponding region of the detachable cap 30. Wherein, the ventilation cavity 13 is formed among the cavity 26, the first sealing device 24 and the corresponding area of the detachable cover 30, and the corresponding area of the detachable cover 30 is provided with a cooking cavity communication hole 33. I.e. the venting chamber 13 is enclosed by the chamber portion 26 of the liner cap 20, the corresponding area of the removable cap 30 and the first sealing means 24. The cavity portion 26 generally forms a top wall of the venting cavity 13 and the corresponding region of the removable cover 30 generally forms a bottom wall of the venting cavity 13 and the first sealing device 24 generally forms a side wall of the venting cavity 13. It will be appreciated that the first seal 24 is configured in a cylindrical shape.

Preferably, the cavity portion 26 is recessed with respect to the body portion 25 toward a side of the liner cap body 21 facing away from the cooking space 54.

Specifically, the body portion 25 is provided with a cavity portion aperture 27, and the cavity portion 26 is connected to an edge 27A of the cavity portion aperture 27 and/or a periphery of the edge 27A of the cavity portion aperture 27. Preferably, the cavity 26 is connected to the periphery of the edge 27A of the cavity opening 27 and serves to compress the first sealing means 24 to the body 25 at the periphery of the edge 27A of the cavity opening 27.

For example, the outer periphery of the first sealing device 24 is provided with a sealing device groove 24A, and the first sealing device 24 extends through the cavity opening 27 such that the inner periphery 27A of the cavity opening 27 is received in the sealing device groove 24A such that a portion of the first sealing device 24 is located on the upper side of the cavity opening 27 and a portion is located on the lower side of the cavity opening 27. The cavity 26 contacts and connects the body 25 from the upper side of the cavity opening 27. For example, the cavity 26 is provided with a cavity mounting portion 26A, and the body 25 is correspondingly provided with the cavity mounting portion 26A and the body mounting portion 25A connected by bolts. Thus, the cavity 26 presses the portion of the first sealing device 24 located on the upper side of the cavity opening 27 to the body 25 at the periphery of the edge 27A of the cavity opening 27.

In some embodiments not shown herein, the cavity 26 and the first sealing device 24 each extend through the cavity aperture 27, the cavity 26 being adapted to compress the first sealing device to the body portion 25 in a radial direction of the cavity aperture 27. For example, the cavity 26 is located inside the first sealing means 24, i.e. the inner periphery 27A of the cavity opening 27 contacts the outer surface of the first sealing means 24, the cavity 26 contacts the inner surface of the first sealing means 24, and the first sealing means 24 has a certain elasticity so as to be clamped between the cavity 26 and the inner periphery 27A of the cavity opening 27.
