Embodiment Construction

[0018] The present invention is further described below in conjunction with schematic diagram of principle and schematic diagram in accompanying drawing:

[0019] Figure 1 is a schematic diagram of the principle of a radiation-eliminating device for a radiation-free induction cooker, which mainly includes: the lower cover of the housing (1), the upper cover of the housing (2), the support panel (3), the cooking pot body (4), and the pot contact pad (5), a radiation absorbing layer (6), an electromagnetic conversion working circuit (7), and a power ground wire (8). In the accompanying drawings, the power ground wire (8) is connected to the radiation absorbing layer (6) and the pot body contact pad (5), the cooking pot body (4) fully contacts the pot body contact pad (5), and passes through the pot body The contact pad (5) and the radiation absorbing layer (6) form a complete shielding case. When the electronic circuit in the shielding case generates electromagnetic radiation, t...

Abstract

The apparatus comprises; a case bottom cap, a case upper cap, a supporting panel, a cooking kettle, a kettle cushion, a radiation absorbing layer, a electromagnetic switch working circuit and a power earth line. In the case there is a radiation absorbing layer, and the functional device of the induction cooker is mounted in the case; the power earth line is connected to the radiation absorbing layer and the kettle body; the kettle cushion and the radiation absorbing layer forms a shielded enclosure used for absorbing the electromagnetic radiation generated by the electronic circuit. The absorbed electromagnetic radiation is released through the power earth line.

Description

technical field [0001] The invention relates to the field of shielding to reduce or eliminate electromagnetic radiation of electrical equipment, in particular to a radiation-eliminating device for a non-radiation electromagnetic cooker capable of shielding and absorbing electromagnetic radiation and eliminating it through a ground wire in a power supply. technical background [0002] In recent years, induction cooker has become a rookie of household appliances because of its high thermal efficiency and has entered thousands of households. Its working principle is: the AC power is converted into DC through a rectifier, and the DC is converted into a high-frequency AC of 20-30KHZ through a high-frequency power converter, and then the high-frequency AC is added to the flat hollow spiral electromagnetic induction coil. This produces a high-frequency alternating magnetic field, whose magnetic field lines penetrate the heat-resistant supporting panel set above the stove shell and ...
