External electromagnetic radiation absorption technique of electromagnetic furnace

Abstract

The invention relates to an external electromagnetic radiation absorption technique of an electromagnetic furnace. A panel and a bottom cover are of anti-radiation structures with interlayers, the middle layer of the panel is a non-magnetic metal plate, the middle layer of the bottom cover is a magnetic metal plate, and the inner and outer faces of the interlayer of the bottom cover are insulating layers; a circular hole is formed on the metal plate in the middle layer of the panel, the circular hole and a heating coil in the furnace share the same center of the circle, and the diameter of the circular hole is greater than or equal to that of the heating coil; the panel is provided with a conductor contacted with a pot bottom and a connecting line, and the connecting line bypassing the rear edge or the left and right sides of the panel enters into the electromagnetic furnace to be connected with an electromagnetic absorption circuit; a shielding frame is arranged below an operation display part at the front end of the panel, the operation display circuit is mounted in the shielding frame and digital and LED display and touch buttons are exposed, and the shielding frame is connected with the electromagnetic absorption circuit; the other end of the electromagnetic absorption circuit is connected with the metal plate of the middle interlayer of the bottom cover and a protective grounded wire (E) of a single-phase three-core power supply line. Various external electromagnetic radiation absorption schemes are preferable.

Description

technical field [0001] The invention relates to an induction cooker, in particular to an electromagnetic radiation absorption technology outside the induction cooker. Background technique [0002] In 2001, the International Agency for Research on Cancer, a subsidiary of the World Health Organization, designated low-frequency magnetic fields as suspected carcinogens. Indicates that the intensity of electromagnetic waves leaking from the edge of the induction cooker is very large, which is beyond the tolerance of the human body. Electromagnetic radiation is the fourth largest new source of pollution after air pollution, water pollution, land and environmental pollution. The new "public nuisance". [0003] Air and water pollution can be seen intuitively, and can be avoided and vigilant in time through the color and smell of air and water. Electromagnetic pollution is an invisible killer that cannot be seen or touched! When people use more and more and more and more popular h...
