An air supply assembly 100 and a cooking appliance 200 provided according to some embodiments of the present invention are described below with reference to fig. 1 to 5.

According to a first aspect of the present invention, as shown in fig. 1 and fig. 2, there is provided an air supply assembly 100, which includes a spiral case 110, a fan 120 and an air guide member 130, wherein the spiral case 110 includes an air inlet 112 and a holding cavity 111, the fan 120 is disposed in the holding cavity 111, and the air guide member 130 is located on an air inlet side of the fan 120 and extends toward the air inlet 112.

The utility model provides an air supply assembly 100, including spiral case 110, fan 120 and wind-guiding piece 130, spiral case 110 holds chamber 111 including having both ends open-ended, and an opening that holds chamber 111 is air intake 112, and another opening that holds chamber 111 is air outlet 113, and fan 120 establishes in holding chamber 111, and fan 120 can guide the air current to get into by air intake 112 and hold chamber 111 to discharge from air outlet 113. The air guide member 130 is located on the air inlet side of the fan 120, and the air flow can be guided to the air inlet 112 along the air guide member 130 as much as possible by the guiding of the fan 120, so that the air flow is smoothly discharged through the air outlet 113 to drive the hot air flow to be discharged to the outside, thereby accelerating the air flow circulation of the whole machine, reducing the overall temperature rise, and improving the safety use performance of the cooking appliance 200 with the air supply assembly 100. Compared with the related art, the airflow is easy to form a vortex at the connection between the volute 110 and other components, that is, the hot airflow is easy to accumulate at the crack and is difficult to enter the air inlet 112, so that the fan 120 cannot fully exert the cooling capacity, the airflow circulation efficiency of the air supply assembly 100 is reduced, the temperature of the cooking appliance 200 is increased too high, and the safety hazard exists, and in addition, the airflow forms a vortex and generates noise, and the user experience of the air supply assembly 100 is also affected.

If the air guiding surface 131 is a plane, the plane where the air guiding point M is located needs to pass through the air inlet 112, so that the air flowing along the air guiding surface 131 can enter the air inlet 112. If the wind guide surface 131 is a curved surface, it is necessary to ensure that the tangent plane of the wind guide point M can pass through the wind inlet 112, that is, the airflow is guided along the curved surface, and when the wind guide point M is separated from the curved surface, the airflow can enter the wind inlet 112 along the tangent plane of the wind guide point M. That is, the air guiding surface 131 is matched with the height of the air inlet 112 in the height direction, so that the air flow guided by the air guiding surface 131 can smoothly enter the air inlet 112 and be sucked out by the fan 120, thereby improving the cooling efficiency of the fan 120 and reducing the temperature rise of the cooking appliance 200. It should be noted that the plane or the tangent plane where the wind guiding point M is located may pass through the middle portion of the wind inlet 112, or may pass through the lower portion of the wind inlet 112, as long as the airflow can enter the wind inlet 112.
