Summary of the Invention

[0003] To overcome the above deficiencies, the purpose of the utility model is to provide a cooking appliance with a back blowing and top sweeping structure to the art, so as to solve the technical problem that there are fewer through holes provided at the inner liner above the pot body to communicate with the side air vents of the inner liner, and left and right sweeping diversion plates are arranged at the orifice of the through hole at the inner liner above the pot body, and one side of the pot body at the side air vent of the inner liner is open in the existing similar products, resulting in poor food cooking and processing effects. Its purpose is achieved through the following technical solutions.

[0004] A cooking appliance with a back blowing and top sweeping structure. A handle is provided on one side of the pot body of the cooking appliance. The pot body is placed into the pot body cavity with an opening on one side of the body through the handle. On the back of the pot body cavity on the other side of the body opening symmetrically, there is a through hole communicating with the channel cavity. A centrifugal air blade is provided in the channel cavity. The rotating shaft at the motor in the body extends into the channel cavity and is connected to the centrifugal air blade. In front of the centrifugal air blade on one side of the pot body in the channel cavity, there is a heating tube. The heating tube and the motor are connected to the circuit board through wires. The key point of its structural design is that the channel cavity extends upwards to communicate with the diversion hole above the pot body in the body. At the diversion hole, there are left and right sweeping diversion plates that swing through a movable rotating shaft. The channel cavity where the centrifugal air blade and the heating tube are provided is a wind guide cover. The through hole is arranged on the wind guide cover, and the top opening of the wind guide cover communicates with the channel cavity. Thus, the diversion of the hot air above the pot mouth of the pot body is strengthened by the left and right sweeping diversion plates and enters the pot body downward.

[0005] On the pot body on one side of the centrifugal air blade and the heating tube, there is a pot body ventilation hole, and the pot body ventilation hole is aligned with the through hole at the wind guide cover. Thus, the hot air in the pot body is further diverted out through the pot body ventilation hole and enters the channel cavity through the through hole.

[0006] A grill is provided at the bottom inside the pot body. The plate body of the grill is provided with hollow holes. The pot body ventilation holes include a pot body ventilation hole a on one side of the pot body above the grill and a pot body ventilation hole b on one side of the bottom of the pot body below the pot body ventilation hole a. The above is a specific structural design of the pot body ventilation holes, which is convenient for the diversion of hot air above and below the grill.

[0007] The diameter of the through hole at one side above the pot body ventilation hole b is greater than half of the diameter of the pot body ventilation hole a. Thus, the hot air at the pot body ventilation hole b below the grill in the pot body enters the through hole upwards, and the hot air at the pot body ventilation hole a in the pot body above the grill enters the through hole downwards, forming an aggregation effect and a pressure change effect.

[0008] The diversion hole above the pot body, and the movable rotating shaft and the left and right sweeping diversion plates are arranged in the groove at the top inside the body. Thus, the pot mouth above the pot body fits closer to the top of the pot body cavity inside the body, and the aggregation effect of the hot air in the pot body is better.

[0009] A heating tube is provided in the groove outside the movable rotating shaft and the left and right sweeping diversion plates at the top inside the body. The heating tube is connected to the circuit board through wires. Thus, the temperature of the pot body cavity inside the body above the pot body is increased by the heating tube, further enhancing the effect of the hot air in the pot body cavity and meeting the temperature requirements of different foods during cooking and processing.

[0010] The flat key shaft at the movable rotating shaft is connected to the swing shaft motor. The swing shaft motor is connected to the circuit board through wires. The swing shaft motor drives the left and right sweeping diversion plates to swing through the movable rotating shaft.

[0011] The structure design of the utility model is simple and reasonable, with good diversion and heating effects, fast food cooking and processing, and wide application range in ovens. It is suitable for use as a cooking appliance with a back-blowing and top-sweeping structure, as well as the structural improvement of similar products. BRIEF DESCRIPTION OF THE DRAWINGS
