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 It is a schematic diagram of the principle of an induction cooker without external radiation, mainly including: shell base (1), shell cover (2), shielding panel (3), cooking pot body (4), shell radiation absorbing layer (5), electromagnetic conversion Working circuit (6), power ground wire (7). In the accompanying drawings, the power ground wire (7) is connected to the radiation absorbing layer (6) shielding panel (3), the cooking pot body (4) is fully in contact with the shielding panel (3), and passes through the shielding panel (3) and the shell The radiation absorbing layer (5) forms a complete shielding case. When the electronic circuit in the shielding case generates electromagnetic radiation, it can be shielded and absorbed by the shielding case, and then the ground wire (7) in the power line is c...

Abstract

The invention discloses an external radiation-free electromagnetic oven. The external radiation-free electromagnetic oven is composed of a shell pedestal, a shell top cover, a shielding panel, a cooking pot body, a shell radiation absorbing layer, an electromagnetic transition work circuit and a power supply ground wire. The shell pedestal, the shell top cover and the shielding panel form a complete shell, the radiation absorbing layer is arranged in a corresponding position of the shell, and functional devices of the electromagnetic oven are installed in the shell; and the power supply ground wire is connected with the shell radiation absorbing layer and the shielding panel, the cooking pot body fully contacts with the shielding panel, the shielding panel and the shell radiation absorbing layer form a complete shield cover body, and when an electronic circuit at the inner side of the shell shield cover body, shielding absorption of the shield cover body is realized, and the ground wire in power lines is connected with the ground to carry out discharge elimination in order to eliminate the hazards of discharged electromagnetic radiation during the working of the electromagnetic oven. The external radiation-free electromagnetic oven can be used in fields of household electromagnetic ovens, chafing dish electromagnetic ovens, tea electromagnetic ovens, cabinet electromagnetic ovens and electromagnetic cookers, and industrial and commercial electromagnetic induction heating fields.

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-free electromagnetic cooker capable of shielding and absorbing electromagnetic radiation and eliminating it through a ground wire in a power supply. Background technique [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 act on the metal pot placed on the...
