More preferably, the two air circulation parts 150 are symmetrically arranged with respect to the heating assembly 130, which not only facilitates the manufacturing process, but also further improves the temperature balance in the cover body.

A heat sink 170 is disposed within the air circulation 150 to enable air to enter the cavity 140 via one of the two air channels 151 and exit via the other. That is, air enters the air inlet duct from the air inlet, then enters the cavity to exchange heat with the heating assembly 130, then enters the air outlet duct, and finally is discharged from the air outlet.

Illustratively, one heat sink 170 is provided in one of the two air flow channels 150, or one heat sink 170 may be provided in both air flow channels 150. Preferably, the heat sink 170 is configured as a fan. The heat sink 170 can be arranged in a forward direction or a reverse direction, i.e., the air inlet duct and the air outlet duct can be interchanged.

According to the utility model discloses a lid 100, air follow an air passage 151 entering cavity 140, leave from another air passage 151 again after the heat exchange with heating element 130, can reduce the temperature in the lid 100 for the temperature is unlikely to exceed standard, maintains heating element 130's intensification and radiating balance.

Specifically, please refer to fig. 2. The connection of the liner 120 and the sidewall 152 is provided with an opening 123, and the air passage 151 communicates with the cavity 140 via the opening 123.

The air is thus disposed to contact the heating element 130 through the opening 123, thereby improving heat dissipation efficiency and facilitating maintenance of temperature balance in the cover 100.

Please refer to fig. 2 and 3. The air circulation unit 150 is substantially constituted by a side wall 152 and a top cover 153. Wherein a sidewall 152 is disposed on the liner 120 and a top cap 153 is attached to the sidewall 152, thereby forming an air channel 151. In order to improve the sealing performance of the air passage 151 and improve the amount of air entering the cavity 140, a groove 154 is provided on the top of the side wall 152, a sealing member 155 is provided in the groove 154, and the bottom end of the top cover 153 is inserted into the groove 154 and abuts against the sealing member 155.

The side wall 152 is specifically composed of a first side wall 156, a second side wall 157, and a third side wall 158. A first side wall 156, a second side wall 157, and a third side wall 158 are all provided on the liner 120, wherein the first side wall 156 and the second side wall 157 are both provided along the extending direction of the air passage 151, and the second side wall 157 is located inside the first side wall 156, i.e., the second side wall 157 is closer to the center of the cover body 100 than the first side wall 156. A third sidewall 158 is connected between the first and second sidewalls 156 and 157 and is configured as an end of the air flow channel 150 distal from the tuyere 111. And, the opposite side of the third sidewall 158 is the tuyere 111.

The air circulation portion 150 is provided therein with a stopper 159 for mounting the heat sink 170. The stopper 159 includes two stopper ribs 160, and the two stopper ribs 160 are disposed on the first sidewall 156 or the second sidewall 157 to be spaced apart from each other, whereby the heat sink 170 may be disposed between the two stopper ribs 160. In an alternative embodiment, one air circulation portion 150 is provided with one position limiting portion 159, i.e., two position limiting ribs 160. Preferably, two position-limiting portions 159, i.e., four position-limiting ribs 160 are provided in one air circulation portion 150. The two stoppers 159 are respectively disposed on the first and second sidewalls 156 and 157 and correspond to each other. This arrangement further improves the mounting stability of the heat sink 170, and reduces the possibility of displacement of the heat sink 170 when the cooking appliance is moved.
