Example Embodiment

[0016] Example 1: This example includes an inner tank 1 , an outer tank 2 , a vacuum connection layer 3 and an electric heating device 4 . The inner tank is composed of an upper inner tank 11 and a bottom inner tank 12; the electric heating device 4 is composed of an aluminum alloy heat dissipation material and an electric heating wire arranged in the aluminum alloy heat dissipation material, and is located between the inner tank 1 and the vacuum connection layer 3. , the aluminum alloy heat dissipation material is placed on the back of the bottom inner tank 12, and the bottom inner tank 12 is welded with bottom cover. An anti-dry-burning device and a temperature sensor may be provided on the back of the bottom inner pot 12 . The outer bladder is composed of an upper outer bladder 21 and a bottom outer bladder 22, and the upper outer bladder 21 and the bottom outer bladder 22 are sealed and welded together at the corners. The backside of the bottom of the inner container in t...

Example Embodiment

[0017] Embodiment 2: This embodiment includes an inner bladder 1 , an outer bladder 2 , a vacuum connection layer 3 and an electric heating device 4 . Its structure is basically the same as that of Example 1, the difference is that the bottom liner 12 is provided with a downward folded edge 8, and the outer end of the vacuum connection layer 3 is sealed and welded with the outer end of the lower folded edge 8 of the bottom liner 12. , a sinking circular step is processed along the circumferential direction on the outer surface of the bottom folded edge of the bottom liner 12, and the lower end of the upper liner 11 is sleeved on the sunk circular step of the bottom folded edge 8 of the bottom liner, and sealed and welded with it , can fully guarantee the welding quality.

[0018] After the above structure is adopted in the present invention, the manufacturability of the vacuum electric heating container bladder structure can be greatly improved, the welding is convenient, the ...

Abstract

A main body structure of an electrically heated container with vacuum layer is composed of an internal container, an external casing, a sealed vacuum layer between said internal container and external casing, and an electric heater with power cord and signal lines. Its all units are welded for high sealing performance.

Description

technical field [0001] The invention relates to a vacuum electric heating container, in particular to a vacuum electric heating container gall body structure. Background technique [0002] The separate three-layer vacuum electric heat preservation vessel is an invention patent applied by the applicant on January 6, 2004. The patent number is 200410012628. It can keep warm, but because the heating layer is located at the bottom of the inner tank, it is inconvenient to weld with the inner tank, and the processing technology of the inner tank is not good, which often affects the quality of the pot body. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned background technology, and propose a vacuum electric heating vessel body structure with reasonable structure and convenient welding, so that it can meet the welding requirements, improve the processing technology of the liner body, and ensure the quality ...
