Magnetic conduction heating structure and cooking utensil

Abstract

The invention provides a magnetic conduction heating structure and a cooking utensil.f The magnetic conductive heating structure comprises a plurality of material layers. The thickness of each material layer meets the following formula: alpha is an equivalent heating coefficient of the magnetic conduction heating structure, delta1 to deltan are the thicknesses of the first layer of material to the nth layer of material of the magnetic conduction heating structure from outside to inside, lambda1 to lambdan are heat conductivity coefficients of the first layer of material to the nth layer of material of the magnetic conduction heating structure from outside to inside, rho1 to rhon are densities of the first layer of material to the nth layer of material of the magnetic conduction heating structure from outside to inside, c1 to cn are the specific heat capacities of the first layer of material to the nth layer of material of the magnetic conduction heating structure from outside to inside, h is the height of the magnetic conductive heating structure, the unit is mm, and a, b and c are all constants. According to the technical scheme, the defect that in the prior art, the heating efficiency of an inner pot of an electric cooker is low is overcome.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, in particular to a magnetic conduction heating structure and a cooking utensil. Background technique [0002] IH rice cookers are cooking utensils that heat food through the principle of electromagnetic induction. Energy efficiency is an important evaluation index for the basic performance of rice cookers, and products with low energy efficiency will be gradually eliminated. Since the energy efficiency of IH rice cookers is generally higher than that of heating plate rice cookers, high-energy-efficiency products represented by IH technology have become the main trend in the development of the rice cooker industry. [0003] The working principle of the IH rice cooker is roughly as follows: the coil plate at the bottom of the pot input a high-frequency alternating current, the current flows through the exciting coil to generate an alternating magnetic field, the alternating magnetic field ...
