Electric kettle heating disc

Abstract

The invention discloses an electric kettle heating disc, comprising a first heat conductive plate and a second heat conductive plate which are oppositely arranged in parallel, and a heating tube and aheat conductive block are arranged between the first heat conductive plate and the second heat conductive plate. The heating tube and the heat conductive block are arranged in a horizontal coplane manner, the heating tube closely fits and surrounds the outer side of the heat conductive block, the first heat conductive plate closely fits the top surfaces of the heating tube and the heat conductiveblock, and the second heat conductive plate closely fits the bottom surfaces of the heating tube and the heat conductive block. The top surface of the first heat conductive plate is provided with a temperature controller erection bolt. The electric kettle heating disc solves the following problems through improvement on various aspects: on the premise of no much cost increase, the external diameter of an electric kettle is remarkably reduced; in addition, under the condition that the external diameter of the heating tube is limited, the heating power of the electric kettle can be increased; furthermore, under the condition of larger heating power, the noise for boiling water can be reduced, and water scale cannot be easily formed on the surface of the heating tube.

Description

technical field [0001] The invention relates to the technical field of an electric kettle assembly, in particular to a small-sized heating plate or a high-power heating plate of an electric kettle equipped with an anti-dry heating thermostat. Background technique [0002] Small electric kettles are popular in the market because of their small size and portability; however, usually electric kettles need to be equipped with a dry-heating thermostat, and the limitation of the dry-burning thermostat makes their outer diameter larger. Small electric kettles have not been able to achieve the ideal size expected by consumers. By installing an intelligent circuit to replace the electric kettle with a dry heating thermostat, the smaller volume can be achieved, but the manufacturing cost of the electric kettle is relatively high, so it is necessary to provide a device that can significantly reduce the cost without increasing the cost much. The scheme of the outer diameter of the smal...

AI Technical Summary

Problems solved by technology

[0002] Small electric kettles are popular in the market because of their small size and portability; however, usually electric kettles need to be equipped with a dry-heating thermostat, and the limitation of the dry-burning thermostat makes their outer diameter larger. Small electric kettles have not yet achieved the ideal size consumers expect

By installing an intelligent circuit to replace the electric kettle with a dry heating thermostat, the smaller volume can be achieved, but the manufacturing cost of the electric kettle is relatively high, so it is necessary to provide a device that can significantly reduce the cost without increasing the cost much. The scheme of the outer diameter of the small electric kettle

[0003] In addition, limited by the outer diameter of the small electric kettle, the outer diameter of the heat pipe of the small electric kettle in the prior art cannot be made larger, resulting in a small heating power of the small electric kettle, and the boiling time of the small electric kettle is too long

Thirdly, the small size of the heating tube in the prior art is relatively small. In the case of high heating power, the heat transfer area of ​​the heating tube is insufficient, resulting in high noise for boiling water and the surface of the heating tube is prone to scale formation.
