Abstract

The invention relates to an electric heater applied to cooking equipment, in particular to an electric heater comprising a plurality of planar heating elements capable of heating at high temperature within a limited area. The present invention provides an electric heater, comprising: a substrate; a first planar heating element formed on one side of the substrate; and a second planar heating element formed on one side of the substrate so as to be located on the first surface The outer side of the shape heating body, the first planar heating body includes: a first pattern part, connecting the starting point and the end point, and a pair of first electrode parts, connected with the first pattern part, and the second planar heating element The body includes: a second pattern part, surrounding a part of the outer periphery of the first pattern part and connecting the start point and the end point, an opening part is formed on one side of the second pattern part, and a pair of second electrode parts, connected to the first pattern part The second pattern part is connected.

Description

technical field [0001] The invention relates to an electric heater applied to cooking equipment, in particular to an electric heater comprising a plurality of planar heating elements capable of heating at high temperature within a limited area. Background technique [0002] In general, a cooking device is a device that uses gas or electricity to heat food for cooking. Microwave ovens using microwaves, ovens using heaters, gas ranges using gas, electric ranges using electricity, built-in gas ranges or Various products such as cooktops for electric stoves. [0003] Gas stoves use gas as a heat source and generate flames directly, while electric stoves use gas and electricity to heat containers and food placed on the plate. [0004] Gas stoves have a large heat loss due to flames and pollute the indoor air with pollutants discharged from incomplete combustion, so electric stoves have recently attracted attention. [0005] Electric stoves can be divided into induction stoves, ...
