Container for generating heating effect by utilizing mode of electromagnetic induction heating

Abstract

The invention discloses a container for generating a heating effect by utilizing a mode of electromagnetic induction heating, which comprises an insulating adiabatic material body, wherein a nonmagnetic metal thin layer is arranged on an inner surface of the insulating adiabatic material body. The container provided by the invention has reasonable structure, high heating speed, good heat-insulation effect and no leakage of electricity, and is widely applied to people's lives.

Description

technical field [0001] The invention relates to a container which generates heating effect by means of electromagnetic induction heating. Background technique [0002] At present, there are commonly used electromagnetic induction heating containers on the market. For example, induction cookers heat magnetically conductive materials (such as iron, nickel, cobalt, etc.). The inner and outer surfaces of the metal cooker are provided with a magnetic metal layer. When they are placed on the induction cooker, the induction coil in the induction cooker is energized to generate an alternating magnetic field. Variable current (ie, eddy current), eddy current makes the magnetic metal move irregularly at high speed, and the molecules collide and rub against each other to generate heat energy, which makes the magnetic metal itself generate heat at high speed, which is used to heat and cook food, so as to achieve the purpose of cooking; Although some cooking utensils directly made of ma...

[0002] At present, there are commonly used electromagnetic induction heating containers on the market. For example, induction cookers heat magnetically conductive materials (such as iron, nickel, cobalt, etc.). The inner and outer surfaces of the metal cooker are provided with a magnetic metal layer. When they are placed on the induction cooker, the induction coil in the induction cooker is energized to generate an alternating magnetic field. Variable current (ie, eddy current), eddy current makes the magnetic metal move irregularly at high speed, and the molecules collide and rub against each other to generate heat energy, which makes the magnetic metal itself generate heat at high speed, which is used to heat and cook food, so as to achieve the purpose of cooking; Although some cooking utensils directly made of magnetically conductive metals heat quickly, the heat preservation effect of metal materials is poor. Slower, in view of the above shortcomings, it is necessary to make improvements
