Ceramic electric kettle

Abstract

The invention discloses a ceramic electric kettle, and relates to the technical field of ceramic processing. The ceramic electric kettle comprises a ceramic kettle body, a heating tube and a heat insulation bottom cover. The heating tube is approximately spiral, the heating tube is fixedly arranged on the heat insulation bottom cover and is electrically connected with a plug on the heat insulationbottom cover, and the heat insulation bottom cover is fixedly arranged on the bottom surface of the ceramic kettle body; the bottom surface of the ceramic kettle body is provided with a mounting groove which is approximately spiral and is used for embedding the heating tube; the cross section profile of the mounting groove is semicircular; and the surface of the mounting groove is coated with a layer of heat-conducting silica gel film which is tightly attached to the heating tube. After the ceramic kettle body is formed, the bottom surface is independently polished, and the spiral mounting groove is formed in the bottom, so that the bottom surface can be thinned, the heat conduction effect can be ensured, and the strength of the bottom surface can be well ensured; and the full-ceramic inner container is realized, so that the problem of secondary pollution of drinking water due to the fact that a stainless steel inner container is easy to form incrustation and even rust is solved.

Description

technical field [0001] The invention relates to the technical field of ceramic processing, and more specifically refers to a ceramic electric kettle. Background technique [0002] The inner layer of the body of the existing electric kettle is usually made of aluminum alloy. In order to facilitate better heat transfer with the electric heating tube at the bottom of the kettle, the inner surface of the existing kettle body, especially the inner bottom surface, is made of stainless steel. . Although the inner bottom surface made of stainless steel has a good heat conduction effect, it is easy to form scale after a long time, and some stainless steel materials of poor quality will also rust, causing secondary pollution of drinking water and affecting people's health. [0003] Ceramic is a good thermal conductivity material, which is one of the most common materials for containers. At present, there are some ceramic electric kettles on the market, but these ceramic electric ket...

AI Technical Summary

Problems solved by technology

At present, there are some ceramic electric kettles on the market, but these ceramic electric kettles still use stainless steel products as the inner bottom surface, which cannot solve the above problems. The main reason is that the thermal conductivity of ceramics itself is not as good as that of stainless steel. Due to the limitations of the existing ceramic technology and the hardness of the ceramic material itself, the bottom surface of the ceramic pot body cannot be made as thin as stainless steel alone, which makes the heating effect of the all-ceramic electric kettle product poor and the competitiveness is poor. ceramic electric kettle
