no. 1 approach

[0033] Please also refer to Figure 1 to Figure 3 Shown is the first embodiment of a safe electromagnetic heating device of the present invention. This embodiment takes an electromagnetic cooker as an example to illustrate the beneficial effects of the present invention. The safe electromagnetic heating device includes a radiation-proof housing 11, an electromagnetic coil 12 located in the radiation-proof housing and a cooling fan (not shown in the figure). The radiation-proof housing includes an upper shell 111 and a lower shell 112. The shell 111 is provided with a heating area 113 for placing a pot, and the lower shell 112 is provided with an air inlet and an air outlet of a cooling fan. The upper case 111 includes an electromagnetic reflection sheet 114 and an electromagnetic absorption sheet 115, the lower case includes an electromagnetic reflection sheet 116 and an electromagnetic absorption sheet 117, and the electromagnetic reflection sheets (114, 116) are located insi...

Embodiment approach 2

[0046] see Figure 4 The shown second embodiment of a safety electromagnetic heating device of the present invention is different from the first embodiment in that the electromagnetic reflection sheet of the lower shell includes a first electromagnetic reflection sheet 21 and a second electromagnetic reflection sheet 22, the second electromagnetic reflection sheet An electromagnetic reflection sheet 21 is fixed on the inner bottom surface of the lower case, and a second electromagnetic reflection sheet 22 is fixed on the side of the electromagnetic coil. The first electromagnetic reflection sheet and the second electromagnetic reflection sheet are mutually separated structures, and the second electromagnetic reflection sheet is fixed on the side wall of the lower case.

[0047] Further, in this embodiment, the electromagnetic coil is a circular coil, and the first electromagnetic reflection is a circular reflective sheet with an area larger than that of the electromagnetic coi...

Abstract

The invention relates to a safe electromagnetic heating apparatus, comprising an anti-radiation shell and an electromagnetic wire coil located in the anti-radiation shell. The anti-radiation shell comprises an upper shell and a lower shell; the upper shell is provided with a heating zone used for placing of cookware and comprises an electromagnetic reflector plate and an electromagnetic absorption plate; the lower shell comprises an electromagnetic reflector plate and an electromagnetic absorption plate; the electromagnetic reflector plates are respectively located at the inner sides of the electromagnetic absorption plates; the electromagnetic reflector plate and the electromagnetic absorption plate of the upper shell are provided with openings at positions corresponding to the heating zone; the area of the electromagnetic reflector plate of the lower shell is greater than the area of the projection of the electromagnetic wire coil on the lower shell; and the thickness of the electromagnetic reflector plates is less than 3 mm. According to the invention, high-frequency electromagnetic waves with a frequency greater than 100 KHz are shielded in the electromagnetic heating apparatus by using the electromagnetic reflector plates, so the electromagnetic waves are reflected and attenuated, and the risk of leakage of the high-frequency electromagnetic waves is reduced; and low-frequency electromagnetic waves with a frequency lower than 100 KHz are absorbed by the electromagnetic absorption plates and conducted to the cookware on the electromagnetic heating apparatus, so energy efficiency of the electromagnetic heating apparatus is improved, and leakage of the low-frequency electromagnetic waves is prevented at the same time.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of electromagnetic heating, in particular to a safe electromagnetic heating device. [0003] 【Background technique】 [0004] Due to the high efficiency of electromagnetic heating, it has been widely used in the field of household appliances. [0005] However, if the high-frequency electromagnetic heating field leaks, it will be harmful to the human body. Although the country has formulated a standard for the magnetic leakage of the induction cooker, the safety performance of the induction cooker has been relatively improved. However, the problem of electromagnetic leakage has not been completely solved in the market at all, resulting in a relatively large limitation in the application and promotion of electromagnetic heating technology. [0006] 【Content of invention】 [0007] In view of this, the present invention provides a safer electromagnetic heating device without electromagnetic leakage. [0008] A s...
