[0036] Please refer to Figures 1 to 6 , the present utility model provides an air fry microwave oven with a wind guiding structure, which includes a furnace body 1, an air fryer module 2 and a microwave heating module 3. A cooking cavity 10 is provided inside the furnace body 1, and a hot air hole 101 is provided at the top of the cooking cavity 10; the microwave heating module 3 is arranged outside the cooking cavity 10;

[0037] The air fryer module 2 includes a fryer body 21 and a heating mechanism. The fryer body 21 is slidably assembled in the cooking cavity 10, and the inside of the fryer body 21 is communicated with the hot air hole 101; the heating mechanism is arranged above the hot air hole 101 and includes a heating element 22, a wind guiding component 23, a transmission component 24 and a heat dissipation wind guiding cover 25;

[0040] The bottom of the heat dissipation air guide cover 25 forms a hot air cavity 250 and covers the outer periphery of the heating element 22, so that the heating element 22 is disposed in the hot air cavity 250, and the heating element 22 is wound around the outer periphery of the air guide assembly 23. In a specific embodiment of the present invention, the heating element 22 is a heating tube. When the air fry function is used, the air guide assembly 23 works to deliver air to the heating element 22. At the same time, the heating element 22 works to generate heat to heat the air in the hot air cavity 250 into hot air, and the heat dissipation air guide cover 25 can guide a part of the hot air in the hot air cavity 250 into the hot air hole 101; a fryer body 21 is disposed below the hot air hole 101, and the hot air enters the fryer body 21 through the hot air hole 101 to heat the food in the fryer body 21.

[0041] The microwave heating module 3 is disposed outside the cooking cavity 10. In a specific embodiment of the present invention, the structure and working principle of the microwave heating module 3 can refer to the existing microwave heating mechanism. When the microwave heating module 3 is used for microwave heating, the microwave heating module 3 emits microwaves to the cooking cavity 10 to heat the food in the cooking cavity 10.

[0042] The air fry microwave oven with an air guide structure is provided with a heat dissipation channel 251 on one side of the heat dissipation air guide cover 25, and the outer side of the air guide assembly 23 can introduce another part of the hot air into the heat dissipation channel 251 on the side of the hot air cavity 250 and discharge it outside the product through the heat dissipation channel 251 to play a heat dissipation role; the remaining hot air that has not been introduced needs to be discharged in time to prevent the equipment from malfunctioning due to excessive internal temperature.

[0043] Specifically, the air guide assembly 23 includes a rotating shaft 231 and a turbine air wheel 232; the turbine air wheel 232 is located in the hot air cavity 250; the driving end of the transmission assembly 24 is in transmission connection with the turbine air wheel 232 through the rotating shaft 231.

[0044] The driving end of the transmission assembly 24 drives the turbine wheel 232 to rotate through the rotating shaft 231, so that the turbine wheel 232 rotates in the hot air chamber 250, and the heat generated by the heating element 22 of the hot air chamber 250 enters the fryer body 21 through the hot air hole 101.

[0045] Specifically, the turbine wind wheel 232 includes a wind wheel seat 2321, a wind wheel cover 2322 and a plurality of wind wheel blades 2323, the wind wheel seat 2321 is connected to the driving end of the bearing fixing seat 245, and the wind wheel blades 2323 are circumferentially arranged with the axis of the bearing fixing seat 245 as the axis; a ventilation hole 2324 is provided in the middle portion of the wind wheel cover 2322, the top portion of the wind wheel blade 2323 is connected to the wind wheel blade 2323, and the bottom portion of the wind wheel blade 2323 is connected to the wind wheel blade 2323.

[0046] An exhaust area is formed between the wind wheel seat 2321 and the wind wheel cover 2322, and the multiple wind wheel blades 2323 divide the exhaust area into multiple exhaust channels. When the air guide component 23 is working, the rotating shaft 231 drives the turbine wheel 232 to rotate as a whole; the wind wheel blades 2323 rotate to shear the air in the center of the air guide component 23, so that the air enters the turbine wheel 232 from the ventilation hole 2324 and is discharged from the exhaust channel; then, the air discharged from the outside of the turbine wheel 232 meets the heating element 22, and the heating element 22 heats the air to form hot air, and the generated hot air is guided by the hot air cavity 250, passes through the hot air hole 101 and reaches the cooking cavity 10.

[0047] By adopting the above structure, the turbine wheel 232 has a radial wind guiding function and generates centrifugal air. The air is thrown out from the outside of the turbine wheel 232 and then directly passes through the surface of the heating element 22 to extract the heat from the surface of the heating element 22.

[0048] Specifically, the transmission assembly 24 includes a driving member 241, a transmission wheel 242, a transmission belt 243, a driven wheel 244, a bearing fixing seat 245 and a bearing 246;

[0049] The driving member 241 is arranged on one side of the heat dissipation air guide cover 25, and the driving end of the driving member 241 is connected to the transmission wheel 242; the driven wheel 244 is sleeved on the bearing 246; the transmission belt 243 is sleeved on the outer periphery of the transmission wheel 242 and the driven wheel 244, and the bearing fixing seat 245 is installed on the top of the heat dissipation air guide cover 25; the bearing 246 is rotatably assembled in the bearing fixing seat 245, and the rotating shaft 231 is connected to the bearing 246.

[0050] The bearing 246 is connected to the driven wheel 244. The transmission belt 243 is sleeved on the outer circumferences of the driving wheel 242 and the driven wheel 244. The driving wheel 242 is fixedly connected to the driving member 241. When the air fry function is used, the driving member 241 is started and drives the driving wheel 242 to rotate. The driving wheel 242 drives the driven wheel 244 to rotate through the transmission belt 243, so that the driven wheel 244 drives the rotating shaft 231 to rotate; the rotating shaft 231 drives the turbine air wheel 232 to rotate, thus achieving the purpose of the rotation of the turbine air wheel 232.

[0051] Specifically, the transmission assembly 24 further includes a sub-fan 247. The driving end of the driving member 241 passes out from below the driving member 241 and is connected to the sub-fan 247.

[0052] In a specific embodiment of the present invention, the driving member 241 is specifically a motor. The driving member 241 is a motor, and the driving end of the driving member 241 is a motor driving shaft. The motor driving shaft penetrates through the driving member 241, thus forming two driving ends.

[0053] With the above structure, the driving member 241 has two driving ends. One driving end is arranged at the top for driving the driving wheel 242 to rotate, and the other driving end is arranged at the bottom for driving the sub-fan 247 to rotate. The two driving ends rotate synchronously, so that while the driving end of the driving member 241 drives the driving wheel 242 to rotate, the sub-fan 247 also rotates synchronously. Cooperating with the cooling fan in the microwave heating module 3, the heat in the accommodating cavity 11 can be discharged, preventing the heat from accumulating in the accommodating cavity 11, thereby avoiding the problem that the microwave heating module 3 is prone to failure due to too high temperature.

[0054] Specifically, the heating mechanism further includes a heat insulation cover 26. The heat insulation cover 26 covers the outer circumference of the heat dissipation air guide cover 25. The driven wheel 244 is rotatably assembled on the heat insulation cover 26.

[0055] 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 26 plays a role in heat insulation, avoiding the situation that hot air continues to conduct heat upward through the heat dissipation air guide cover 25, thereby reducing heat loss; at the same time, avoiding the problem that the top temperature of the air fry microwave oven is too high and it is easy to scald the user, enhancing safety.

[0056] Specifically, the furnace body 1 further has an accommodating cavity 11. The accommodating cavity 11 is located on one side of the cooking cavity 10. The microwave heating module 3 and the transmission assembly 24 are arranged in the accommodating cavity 11; a plurality of heat discharge holes 111 communicating with the outside are provided on the side wall of the accommodating cavity 11.

[0057] The accommodating cavity 11 is used to accommodate the microwave heating module 3. In a specific embodiment of the 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, improving the problem of insufficient space in the cooking cavity 10 due to the installation of the air fryer module 2, and rationally utilizing the space. Under the condition of ensuring that the cooking cavity 10 has sufficient space, the height of the air fryer microwave oven is reduced, so that the size of the air fryer microwave oven is more suitable for the existing kitchen environment.

[0058] 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 arranged above the air inlet holes 12 . The side wall of the protective cover 4 is provided with a fence 41 .

[0059] With the above structure, a protective cover 4 is provided, and the protective cover 4 covers the air inlet hole 12 to form an air inlet channel, so as to prevent dust or debris from directly entering the oven body 1 through the air inlet hole 12, thereby reducing the situation where dust or debris affects the internal components of the air frying microwave oven. Air enters the oven body 1 from the air inlet hole 12, and the air inside the oven body 1 is discharged through the heat exhaust hole 111 on the side wall of the accommodating cavity 11.

[0060] Specifically, a guide rail is provided on the upper portion of the cooking cavity 10, and an air fryer with an upper end opening is slidably connected to the guide rail.

[0061] The sliding assembly structure of the air fryer and the cooking cavity 10 can refer to the existing air fryer microwave oven.

[0062] Specifically, it includes a protection device, and the air fryer slides back and forth on the guide rail to trigger the protection device to control the circuit to cut off or turn on the power. The above structure can ensure that the air fryer can be accurately assembled in the heating area, thereby preventing the air fryer from being misplaced and causing the heating efficiency to decrease.

[0063] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementations of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
