The bearing assembly is installed above the heating air inlet 101. The bearing assembly is in transmission connection with the air guide assembly 22.

[0039] The air guide assembly 22 is located above the heating air inlet hole 101 , and the heating element 21 is disposed close to the air guide assembly 22 .

[0040] The transmission assembly 23 adopts a worm gear transmission form, which has a compact structure and is suitable for transmission needs in a limited space, driving the air guide assembly 22 to operate; moreover, the transmission is smooth, the transmission ratio is accurate, and due to the linear contact between the gear teeth, the noise is very small.

[0041] The transmission assembly 23 is placed separately from the air guide assembly 22, which can reduce the overall height of the air fryer module 2, rationally utilize the lateral space of the furnace body 1, save the space at the top of the cooking cavity 10, and improve the problem of insufficient space in the cooking cavity 10 due to the installation of the air fryer module 2. While ensuring that the cooking cavity 10 has sufficient space, the height of the air fryer microwave oven is reduced, making the size of the air fryer microwave oven more suitable for the existing kitchen environment.

[0042] In a specific embodiment of the present invention, the heating element 21 is a heating tube. When the air frying function is used, the air guide assembly 22 operates to deliver air to the heating element 21. Simultaneously, the heating element 21 generates heat, heating the air in the hot air chamber 241 into hot air. A fryer body 26 is disposed below the heating air inlet 101. The hot air enters the fryer body 26 through the heating air inlet 101, heating the food inside the fryer body 26.

[0043] The bearing assembly includes a bearing fixing seat 235 and a bearing 236; the driven wheel 234 is sleeved on the bearing 236; the bearing 236 is rotatably assembled in the bearing fixing seat 235, and the bearing 236 is transmission-connected to the air guide assembly 22; the bearing assembly is installed above the heating air inlet 101.

[0044] The microwave heating module 3 is disposed outside the cooking cavity 10. In the specific embodiment of the present invention, the structure and operating principle of the microwave heating module 3 can refer to existing microwave heating mechanisms.

[0045] Specifically, the air fryer module 2 further includes a wind guide cover 24. A hot air chamber 241 is formed at the bottom of the wind guide cover 24. The heating element 21 and the air guide assembly 22 are respectively disposed in the hot air chamber 241. The wind guide cover 24 is disposed above the heating air inlet hole 101. The bearing fixing seat 235 is installed on the top of the wind guide cover 24.

[0046] The driving member 231 is disposed on one side of the wind guide cover 24. The wind guide cover 24 plays a role in guiding air, and can guide the hot air in the hot air chamber 241 into the heating air inlet hole 101.

[0047] Specifically, the air fryer module 2 further includes a heat insulation cover 25. The heat insulation cover 25 is disposed outside the circumference of the wind guide cover 24. The driven wheel 234 is rotatably assembled on the heat insulation cover 25.

[0048] The density of hot air is usually lower than that of cold air, and hot air usually rises. With the above structure, the heat insulation cover 25 plays a role in heat insulation, avoiding the situation that hot air continues to conduct heat upward through the wind guide cover 24, thereby reducing heat loss; at the same time, avoiding the problem that the top temperature of the air fryer microwave oven is too high and it is easy to scald the user, enhancing safety.

[0049] Specifically, the air fryer module 2 further includes a fryer body 26. The fryer body 26 is slidably assembled in the cooking cavity 10, and the inside of the fryer body 26 is communicated with the heating air inlet hole 101.

[0050] The fryer body 26 is used to hold food, making the food closer to the air fryer module 2, so that hot air can contact the food faster, thereby improving the heating efficiency. The fryer body 26 is slidably assembled in the cooking cavity 10. When using the air fry function, the fryer body 26 is slid out of the cooking cavity 10, food is placed in it, and then the fryer body 26 is reset.

[0051] Specifically, the furnace body 1 further has a receiving cavity 11. The receiving cavity 11 is located on the left, right or rear of the outside of the cooking cavity 10. The microwave heating module 3 is disposed in the receiving cavity 11; the microwave heating module 3 includes a microwave generating component, a microwave stirring component and a microwave output end for inputting microwave into the cooking cavity.

[0052] The accommodating cavity 11 for the driving member 231 is used to accommodate the microwave heating module 3. In a specific embodiment of the present utility model, the accommodating cavity 11 is arranged on one side of the cooking cavity 10, so that the microwave heating module 3 is arranged laterally, thereby saving the space at the bottom of the cooking cavity 10 and improving the problem of insufficient space in the cooking cavity 10 caused by the setting of the air fryer module 2; making rational use of space, reducing the height of the air fryer microwave oven under the condition of ensuring that the cooking cavity 10 has sufficient space, and making the size of the air fryer microwave oven more adaptable to the existing kitchen environment. In this specific embodiment, the side wall of the accommodating cavity 11 is provided with a plurality of heat discharge holes 111 communicating with the outside.

[0053] Optionally, the transmission assembly 23 further includes a secondary fan 237, and the driving end of the driving member 231 passes out from below the driving member 231 and is connected to the secondary fan 237.

[0054] In a specific embodiment of the present utility model, the driving member 231 is specifically a motor. The driving member 231 is a motor, and the driving end of the driving member 231 is a motor driving shaft, and the motor driving shaft penetrates through the driving member 231, thereby forming two driving ends.

[0055] With the above structure, the driving member 231 has two driving ends. One driving end is arranged at the top and is used to drive the transmission wheel 232 to rotate, and the other driving end is arranged at the bottom and is used to drive the secondary fan 237 to rotate. The two driving ends rotate synchronously, so that while the driving end of the driving member 231 drives the transmission wheel 232 to rotate, the secondary fan 237 also rotates synchronously. Cooperating with the heat dissipation fan in the microwave heating module 3, the heat in the accommodating cavity 11 can be discharged to prevent the heat from accumulating in the accommodating cavity 11, thereby avoiding the problem that the microwave heating module 3 is prone to malfunction due to too high a temperature.

[0056] Further, the air guiding assembly 22 includes a rotating shaft 221 and a turbine air wheel 222; the turbine air wheel 222 is located in the hot air cavity 241; the driving end of the transmission assembly 23 is in transmission connection with the turbine air wheel 222 through the rotating shaft 221.

[0057] The driving end of the transmission assembly 23 drives the turbine air wheel 222 to rotate through the rotating shaft 221, so that the turbine air wheel 222 rotates in the hot air cavity 241, and the heat generated by the heating member 21 in the hot air cavity 241 enters the fryer body 26 through the heating air inlet hole 101.

[0058] Furthermore, the turbine wheel 222 includes a wheel seat 2221, a wheel cover 2222 and a plurality of wheel blades 2223, the wheel seat 2221 is connected to the driving end of the bearing fixing seat 235, and the wheel blades 2223 are circumferentially arranged with the axis of the bearing fixing seat 235 as the axis; a ventilation hole 2224 is provided in the middle of the wheel cover 2222, the top part of the wheel blade 2223 is connected to the wheel blade 2223, and the bottom part of the wheel blade 2223 is connected to the wheel blade 2223.

[0059] An exhaust area is formed between the wind wheel seat 2221 and the wind wheel cover 2222, and multiple wind wheel blades 2223 divide the exhaust area into multiple exhaust channels. When the air guide component 22 is working, the rotating shaft 221 drives the turbine wind wheel 222 to rotate as a whole; the wind wheel blades 2223 rotate and shear the air in the center of the air guide component 22, so that the air enters the turbine wind wheel 222 from the ventilation hole 2224 and is discharged from the exhaust channel; then, the air discharged from the outside of the turbine wind wheel 222 meets the heating element 21, and the heating element 21 heats the air to form hot air. The generated hot air is guided by the hot air cavity 241 and passes through the heating air inlet hole 101 to reach the cooking cavity 10.

[0060] The above structure enables the turbine wheel 222 to have a radial wind guiding function and generate centrifugal air. The air is thrown out from the outside of the turbine wheel 222 and then directly passes through the surface of the heating element 21 to extract the heat from the surface of the heating element 21.

[0061] Preferably, a protective cover 4 is further included. The top of the furnace body 1 is provided with a plurality of air inlet holes 12 communicating with the interior of the furnace body 1 . The protective cover 4 is provided above the air inlet holes 12 . The side walls of the protective cover 4 are provided with fences 41 .

[0062] With the above structure, a protective cover 4 is provided. Protective cover 4 covers air inlet 12, forming an air inlet channel. This prevents dust and debris from directly entering oven body 1 through air inlet 12, thereby reducing the risk of dust and debris affecting the internal components of the air fryer. Air enters oven body 1 through air inlet 12 and is discharged through heat exhaust holes 111 in the sidewall of chamber 11.

[0063] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such equivalent variations or substitutions are encompassed within the scope of the claims of this application.
