Electric heating full-vacuum heat preservation kettle

Abstract

The invention discloses an electric heating full-vacuum heat preservation kettle which comprises a kettle lid, a kettle body, a base and a heating assembly. The kettle body comprises a shell, an inner container, a kettle body upper bottom and a kettle body lower bottom. The lower end of the shell is connected with the outer edge of the kettle body upper bottom. The lower end of the inner container is bent inwards to be connected with the inner edge of the kettle body upper bottom to form a heating hole. The inner container, the shell and the kettle body upper bottom form a vacuum layer. The kettle body lower bottom and the lower end of the shell are connected. One end of the heating assembly stretches into the inner container through the heating hole, the other end of the heating assembly is located in the space formed by the kettle body and the kettle body lower bottom, a sealing water outlet device is arranged on the kettle lid, and a pressure relief device is arranged on the sealing water outlet device. The vacuum layer can increase the heat preservation performance and generate the anti-scalding effect; due to the fact that only the heating hole into which the heating assembly can stretch is reserved in the bottom of the kettle body, the area of vacuum heat preservation is increased, heat emitted from the bottom is reduced, the heat preservation effect is improved, one end of the heating assembly directly stretches into the inner container to directly heat liquid, and the heating efficiency is greatly improved.

Description

technical field [0001] The invention relates to an electric kettle, in particular to an electric heating full vacuum insulation kettle. Background technique [0002] The electric heating kettle is a very commonly used heating appliance in daily life at present. It has the advantages of fast water heating and heat preservation, so it is very popular among people. The current electric heat preservation kettle generally achieves the heat preservation effect through the vacuum layer on the side wall of the kettle body, and heats the water in the inner container through the heating plate at the bottom of the kettle body. Although this structure can achieve the purpose of heating and heat preservation, the heating efficiency is low due to the indirect heating through a layer of stainless steel layer during the heating process, and after the heating is completed, the heat in the inner tank is easy to flow from the heating plate. Dissipated, reducing the effect of heat preservation...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the low heating efficiency caused by indirect heating in the prior art, and after the heating is completed, the heat in the inner tank is easily dissipated from the heating plate, which reduces the effect of heat preservation. In addition, the present invention The lid of some electric heating kettles generally only serves to block the water vapor. After heating, the heat in the inner tank can still be dissipated from the water outlet of the kettle body, which will cause the lid to be too hot and may burn the user. , After the kettle is poured, the liquid in the inner tank will flow out directly and wet the countertop, and there will be loud noises when heating and boiling. A new electric heating full vacuum insulation kettle is provided.
