Specifically, it is less likely to achieve the internal air flow guiding of the machine body by simultaneously arranging openings at the bottom of the pot body and on one side of the inner top groove of the cavity, and making the two openings communicate with the inner cavity of the air guide cover where the blower is arranged. Summary of the Invention

[0003] To overcome the above deficiencies, the purpose of the present utility model is to provide a cooking appliance with back blowing and a bottom flow guiding structure to the art, so as to solve the technical problem that the heat air flow guiding effect in existing similar products is poor. Specifically, it is less likely to achieve the internal heat air flow guiding of the machine body by simultaneously arranging openings at the bottom of the pot body and on one side of the inner top groove of the cavity, and making the two openings communicate with the inner cavity of the air guide cover where the blower is arranged, resulting in poor food cooking and processing effects. Its purpose is achieved by the following technical solutions.

[0004] A cooking appliance with a back blowing and bottom flow guiding structure. One side of the pot body of the cooking appliance is provided with a handle extending out of the opening on one side of the inner pot cavity of the machine body. The pot body is placed into the pot cavity on one side of the opening of the machine body through the handle. At the symmetrical back part of the machine body at the opening, a centrifugal fan is provided in the fan cavity, which is connected to the rotating shaft of the motor extending into the fan cavity. The centrifugal fan is horizontally arranged in the fan cavity of the machine body, and the fan cavity where the centrifugal fan is arranged is a wind guide cover. The key point of the structural design is that while the bottom of the fan cavity where the centrifugal fan is arranged is communicated with the inner pot cavity of the machine body through the lower ventilation hole of the pot body, there is a communicated upper ventilation hole of the pot body between the fan cavity on the back of the machine body and the through hole on one side of the groove where the heating tube is arranged above the pot cavity. The heating tube and the motor are connected to the circuit board through wires. Thus, the hot air in the machine body realizes circulation and flow guiding through the upper and lower ventilation holes of the pot body at the inner liner.

[0005] One side of the bottom of the pot body is provided with an opening. When the pot body is placed into the machine body, the opening of the pot body is aligned or sleeved with the lower ventilation hole of the pot body at the wind guide cover in the pot cavity. Thus, the hot air that realizes circulation and flow guiding through the upper and lower ventilation holes of the pot body at the inner liner in the machine body further realizes circulation and flow guiding through the pot body, improving the cooking effect of the food in the pot body.

[0006] Above the opening in the pot body, there is a grill. The plate body of the grill is provided with equally spaced hollow holes. The above grill is set as needed. The grill is placed in the pot body through the limiting ribs formed by stamping the inner diameter of the pot body, or the supporting feet at the bottom of the grill. The flowing hot air realizes circulation in the machine body through the baking tray.

[0007] At the bottom of the grill, there is a flow guiding plate with equally spaced flow guiding holes. Thus, the effect of the hot air passing through the grill at the bottom of the grill is strengthened through the flow guiding plate.

[0008] The flow guiding plate is connected or integrally formed with the plate body of the grill.

[0009] The flow guiding holes of the flow guiding plate are arranged obliquely towards the side of the lower ventilation hole of the pot body. Thus, the flow guiding effect of the flow guiding plate is further improved.

[0010] At the flow guiding holes of the flow guiding plate, there are respectively shutter plates with articulated adjustable directions. Thus, it is further convenient to adjust the flow guiding angle at the flow guiding holes of the flow guiding plate.

[0011] The structural design of the utility model is simple and reasonable, with better flow guiding and heating effects, fast food cooking and processing, and wide application range of ovens. It is suitable for use as a cooking appliance with a back blowing and bottom flow guiding structure, as well as the structural improvement of similar products. Description of the Drawings
