Technical Field

[0001] The invention belongs to the technical field of kitchen appliances, and in particular relates to an air fryer with an electromagnetic heating function and high heat circulation efficiency. Background Art

[0002] At present, there are some air fryers on the market that use electromagnetic heating devices to replace traditional heating tubes. Such air fryers energize the electromagnetic coil to generate induction heating on the heating plate, and then use a hot fan to blow the heat from the heating plate into the cooking cavity to cook the food. The layout of the existing electromagnetic heating device and the hot fan in the hot air cavity of such air fryers is unreasonable, so that when the hot fan is working, the hot air cannot form an effective hot air circulation path between the hot air cavity and the cooking cavity, and the hot air is prone to generate eddy currents and turbulence in the cooking cavity, which easily leads to uneven cooking of food and low thermal energy utilization efficiency. Summary of the invention

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] An air fryer with electromagnetic heating function and high heat circulation efficiency, comprising:

[0006] The fryer body is provided with a cooking cavity;

[0011] Based on the above technical solution: the above layout structure is more reasonable, so that the heating plate is suspended in the hot air cavity, and an air guide channel connected to the air outlet end of the hot fan is formed between the heating plate and the heat insulation cover, which is convenient for the hot fan to quickly blow the heat emitted by the heating plate into the cooking cavity; the electromagnetic coil assembly is arranged between the heat insulation cover and the shielding cover, and the heat insulation cover plays a role of heat insulation, reducing the heat radiation generated by the heating plate in the hot air cavity to the electromagnetic coil, and the cold fan in the cold air cavity can not only dissipate heat for the fan motor when working, but also dissipate heat for the electromagnetic coil assembly.

[0012] A further solution: the heating plate is located directly below the electromagnetic coil assembly, and the air guide channel is located between the heating plate and the electromagnetic coil assembly.

[0013] Based on the above technical solution: the heating plate is located directly below the electromagnetic coil assembly, so that the two are arranged relative to each other, so that after the electromagnetic coil assembly is energized, the heating plate generates electromagnetic induction heating, and at the same time, the structural layout of the two is utilized to form an air guide channel.

[0014] A further solution: the air guide channel includes a first channel located between the upper surface of the heating plate and the top wall of the heat insulation cover and a second channel located between the outer edge of the heating plate and the inner side wall of the heat insulation cover.

[0015] Based on the above technical solution: the above arrangement makes the air outlet end of the hot fan fully connected with the air guide channel in the circumferential direction, and the air guide channel is fully connected with the upper part of the cooking cavity in the circumferential direction. The hot air blown out from the air outlet end of the hot fan can evenly enter the cooking cavity through the air guide channel from the circumferential direction.

[0020] Based on the above technical solution: by setting the lower baffle in the through hole of the heating plate and the upper baffle in the through hole of the heat insulation cover, an air guide channel connecting the cooking cavity and the air outlet end of the hot fan is formed between the heating plate and the heat insulation cover, so that efficient connection is formed between the air outlet end of the hot fan and the air guide channel; the shielding cover can effectively prevent the heat in the hot air cavity from entering the cold air cavity by covering the through hole of the heat insulation cover.

[0021] A further solution is that an annular groove is provided on the upper side of the heat insulation cover, and the electromagnetic coil assembly is arranged in the annular groove.

[0022] Based on the above technical solution: the above arrangement is not only convenient for installing the electromagnetic coil assembly, but also the heat insulation cover plays a role of heat insulation, which can effectively prevent the heat in the hot air cavity from radiating heat to the electromagnetic coil assembly.

Not only is the heat circulation efficiency higher, but the food is also heated more evenly.

[0026] A further solution is that a plurality of arc-shaped guide plates are provided on the heating plate, and the plurality of arc-shaped guide plates are arranged around the center of the heating plate, and an arc-shaped air guide groove with a diameter gradually increasing from the center to the edge of the heating plate is formed between every two adjacent guide plates.

[0027] Based on the above technical solution: by arranging a guide plate on the heating plate, not only the contact area between the heating plate and the hot air is increased, so that the heat of the heating plate can be quickly taken away by the circulating hot air, thereby improving the efficiency of heat energy utilization, but the air guide groove can also guide the hot air blown out from the air outlet of the hot fan into the cooking cavity, making the hot air circulation smoother.

[0028] The beneficial effects of the present invention are:

[0030] By arranging the electromagnetic coil assembly on the hot air chamber cover and setting a cold air chamber between the hot air chamber cover and the cold air chamber cover, the cold fan in the cold air chamber can not only dissipate heat for the fan motor but also dissipate heat for the electromagnetic coil assembly when working, thereby preventing the electromagnetic coil assembly from overheating.
