The term "rear" as defined in the present disclosure is the side of the cooking appliance facing away from the user when the user is using the cooking appliance, and the side of the cooking appliance facing toward the user is referred to as the front. The direction indicated by the hollow arrow in fig. 1 is the front of the headstock 11.

As an example, the air inlet 111 is disposed at the rear of the headstock 11, the headstock assembly 1 and the pot assembly 2 are connected by a rotation shaft, one side of the headstock 11 where the rotation shaft is disposed is the rear of the headstock 11, and the opposite side is the front of the headstock 11.

With continued reference to fig. 2 and 3, the exhaust hood 12 is disposed below the headstock 11, the exhaust hood 12 includes an exhaust hood body 121, an exhaust area of the exhaust hood body 121 is disposed at the rear of the exhaust hood body 121, the exhaust area is provided with an exhaust hole 122, the exhaust hole 122 is communicated with an inner cavity of the exhaust hood body 121 and the outside, and heat dissipation airflow can be exhausted out of the exhaust hood 12 through the exhaust hole 122 to realize exhaust and heat dissipation. Further, the exhaust hole 122 extends along the circumferential direction of the hood body 121, so that the ventilation area of the exhaust hole 122 is increased, and the exhaust effect of the hood 12 is improved.

According to the air exhaust device, the air exhaust area is arranged at the rear of the headstock 11, in the using process of the nose assembly 1, the heat dissipation air flow is exhausted from the exhaust hood 12 through the air exhaust holes 122, and noise generated in the flowing process of the heat dissipation air flow is also transmitted through the air exhaust holes 122, so that the using noise of the nose assembly 1 is reduced, and the user experience of the nose assembly 1 is improved. Further, by arranging the exhaust holes 122 to extend in the circumferential direction of the hood body 121 to increase the ventilation area of the exhaust holes 122 in a limited space, the space utilization of the hood 12 is increased.
