Heating plate for electric kettle, and electric kettle consisting of heating coil

Abstract

The invention discloses a heating plate for an electric kettle, and the electric kettle consisting of the heating plate. The heating plate for the electric kettle has a quasi-circular structure in a horizontal direction, wherein the quasi-circular structure is coiled by one heating pipe; the quasi-circular structure consists of a semi-circular structure A and a semi-circular structure B which are bilaterally symmetrical to each other; the semi-circular structure A comprises a first-layer arc section of which radian is 0 to lambda degrees and takes a circle center as a reference; the first-layer arc section is bent a certain length along an axial direction, and is coiled certain radian so as to form a second-layer arc section with the radian of lambda to 0 degree; and the second-layer arc section is bent a certain length along the axial direction and then is coiled the same radian so as to form a third-layer arc section with the radian of 0 to lambda degrees, wherein the number N of the bent arc sections is more than or equal to 2, the arc section on the innermost layer is connected with the innermost-layer arc section BN of the other semi-circular structure B, the arc sections of the other semi-circular structure B are symmetrical to those of the semi-circular structure A, and lambda degrees are 150 to 170 degrees.

Description

technical field [0001] The invention relates to a household appliance, in particular to a heating plate for an electric kettle and the electric kettle formed therefrom. Background technique [0002] Most of the electric kettle heating methods currently used adopt the bottom heating plate heating method. This heating plate is an aluminum alloy disc with built-in electric heating tubes, and the electric heating tubes in the heating plate are all single-turn Ω-shaped. The electric energy is converted into heat energy through the built-in electric heating tube, and the aluminum alloy disc transfers the heat energy to the stainless steel pot body. During this transfer process, the energy transfer is relatively slow, and a considerable part of the energy is lost during multiple transfers. And because of local high-temperature heating, the bottom of the kettle body that is connected to the heating plate at the bottom is easy to form scale. [0003] When using an electric kettle ...

AI Technical Summary

Problems solved by technology

Due to local high temperature, the heat energy converted from electric energy will be dissipated to the bottom side, reducing energy efficiency

At the same time, the local high temperature leads to aggravated thermal fatigue of the stainless steel pot body at the bottom, and performance degradation

This leads to a reduced service life and increased dissolution of the jug material

At the same time, after the water is boiled, the residual heat of the heating body is relatively large due to insufficient absorption of the food to be cooked.

Therefore, the electric kettle of this traditional structure has multiple use drawbacks
