[0029] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0030] Please refer to the following: Figures 1 to 3This utility model discloses an electromagnetic heating oven, which includes a cavity 1, a rear cover assembly 2, a motor 3, an electromagnetic generator 4, and an electromagnetic induction component 5. The rear cover assembly 2 is located on the rear side of the cavity 1. The motor 3 and the electromagnetic generator 4 are both mounted on the rear cover assembly 2. The motor shaft of the motor 3 is connected to the electromagnetic induction component 5 to drive the electromagnetic induction component 5 to rotate. When the electromagnetic induction component 5 rotates, it generates current under the action of the electromagnetic generator 4 to generate heat and produce hot air, which is then blown into the cavity 1 to increase the temperature inside the cavity 1 and heat the food inside the cavity 1. This design, using the electromagnetic generator 4 to replace conventional heating tube heating, avoids the quality risks associated with traditional metal heating tube heating, thus ensuring the quality of use of the electromagnetic heating oven.

[0031] Among them, the electromagnetic induction component 5 is made of metal, and the electromagnetic generator 4 is an electromagnetic coil winding. When the electromagnetic induction component 5 rotates, it cuts the electromagnetic field generated by the electromagnetic coil winding to generate current, which in turn generates heat and produces hot air.

[0032] In some embodiments, the rear cover assembly 2 includes a support plate 21 and a rear cover plate 22 arranged sequentially from the rear side to the front side of the cavity 1. A motor 3 is located on the side of the support plate 21 facing away from the rear cover plate 22, an electromagnetic generator 4 is located on the side of the support plate 21 facing the rear cover plate 22, and an electromagnetic induction component 5 is located on the side of the rear cover plate 22 facing the cavity 1. The motor 3 passes sequentially through the support plate 21, the electromagnetic generator 4, and the rear cover plate 22 to connect to the electromagnetic induction component 5. With this design, since the electromagnetic induction component 5 directly vents air into the cavity 1, compared to the traditional method where the electromagnetic induction component 5 vents air towards the heating element to blow hot air into the cavity 1, this solution avoids the air duct being blocked by the heating element, making the hot air flow in the electromagnetic heating oven smoother, thereby effectively reducing noise and improving heating efficiency.

[0033] Furthermore, in order to achieve the installation and fixation of the electromagnetic generator 4 on the support plate 21, the rear cover assembly 2 also includes a mounting bracket 23. The mounting bracket 23 is located on the side of the support plate 21 facing the rear cover plate 22. The electromagnetic generator 4 is installed on the mounting bracket 23, and the motor shaft of the motor 3 passes through the mounting bracket 23.

[0034] Furthermore, the rear cover plate 22 is a metal plate to give the rear cover plate 22 greater structural strength. A magnetic flux hole 221 is provided on the rear cover plate 22 at the position corresponding to the electromagnetic generator 4. The electromagnetic field generated by the electromagnetic generator 4 passes through the magnetic flux hole 221 and acts on the electromagnetic induction component 5 to cause the electromagnetic induction component 5 to generate eddy currents and generate heat.

[0035] Furthermore, the support plate 21 is made of a heat-resistant metal material to block the electromagnetic field generated by the electromagnetic generator 4 from being directed at the motor 3. On the one hand, the heat-resistant material ensures that the support plate 21 still has good performance in high-temperature environments; on the other hand, the metal material can block the influence of the electromagnetic field on the motor 3, thereby ensuring that the motor 3 can operate normally.

[0036] In addition, the rear cover assembly 2 also includes an air guide plate 24 with air guide holes. The air guide plate 24 is located on the other side of the electromagnetic induction component 5 opposite to the rear cover plate 22. The electromagnetic induction component 5 blows the generated hot air from the air guide holes into the cavity 1, driving the hot air through the air guide plate 24, so as to achieve the effect of hot air convection to heat the food in the cavity 1.

[0037] In some embodiments, the electromagnetic induction component 5 includes a pot-shaped plate 51 and multiple blades 52. The motor 3 is connected to the pot-shaped plate 51, and the multiple blades 52 are spaced apart on the outer periphery of the pot-shaped plate 51 and extend in the direction toward the cavity 1. With this design, when the electromagnetic field passes through the pot-shaped plate 51, the pot-shaped plate 51 will generate eddy currents and heat up, and the blades 52 will directly dissipate the heat generated by the pot-shaped plate 51 into the cavity 1.

[0038] Furthermore, to prevent the electromagnetic induction component 5 from blowing hot air towards the motor 3 and causing the motor 3 to overheat, the included angle between the blade 52 and the pot-shaped plate 51 is α (e.g., ...). Figure 4 As shown), 90°≤α≤100°. With this design, since the blades 52 have a guiding effect on the hot air, it can ensure that the hot air is blown into the cavity 1 and not blown towards the motor 3.

[0039] In some embodiments, the electromagnetic heating oven also includes a housing with an installation space, in which the cavity 1, rear cover assembly 2, electromagnetic induction component 5, motor 3, and electromagnetic generator 4 are all installed to protect the aforementioned components.

[0040] Furthermore, the housing includes a base 61, an outer shell 62, a furnace door 63, and a rear shell 64. The outer shell 62 is disposed on the base 61, the furnace door 63 is disposed on the front side of the outer shell 62, and the rear shell 64 is disposed on the rear side of the outer shell 62. The base 61, the outer shell 62, the furnace door 63, and the rear shell 64 enclose and form an installation space.

[0041] like Figure 5 As shown, the electromagnetic heating oven of this solution also includes an electric control board 7. The electric control board 7 is located on the side of the support plate 21 away from the rear cover plate 22. The electric control board 7 is electrically connected to the motor 3 to control the start and stop of the motor 3.

[0042] This utility model provides an electromagnetic heating oven, comprising a cavity 1, a rear cover assembly 2, a motor 3, an electromagnetic generator 4, and an electromagnetic induction component 5. The rear cover assembly 2 is located on the rear side of the cavity 1. The motor 3 and the electromagnetic generator 4 are both mounted on the rear cover assembly 2. The motor shaft of the motor 3 is connected to the electromagnetic induction component 5 to drive the electromagnetic induction component 5 to rotate. When the electromagnetic induction component 5 rotates, it generates current under the action of the electromagnetic generator 4 to generate heat and produce hot air, which is then blown into the cavity 1 to increase the temperature inside the cavity 1 and heat the food inside the cavity for cooking. This design, using the electromagnetic generator 4 to replace conventional heating tubes, avoids the quality risks associated with traditional metal heating tubes, thus ensuring the quality of use of this electromagnetic heating oven.

[0043] The above provides a detailed description of an electromagnetic heating oven disclosed in the embodiments of this utility model. This article uses specific examples to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the electromagnetic heating oven of this utility model and its core idea.

Therefore, the content of this specification should not be construed as a limitation of this utility model.
