Liner of vacuum electric heating container and electric kettle

Abstract

The invention provides a liner of a vacuum electric heating container and an electric kettle. The liner of the vacuum electric heating container comprises an inner liner body, a heating device and an outer liner body, wherein the heating device is installed on the bottom of the inner liner body, the outer liner body is connected with the inner liner body in a sealed mode, and a vacuum layer is arranged between the outer liner body and the inner liner body. According to the liner of the vacuum electric heating container, the outer liner body is only arranged on the outer side wall of the inner liner body, and the heating device is arranged on the bottom of the inner liner body, namely the vacuum layer is arranged between the inner liner body and the outer liner body. Compared with the prior art, the liner of the vacuum electric heating container has the advantages that parts related to a vacuum layer on the bottom of the inner liner body are omitted, and thus the production cost is reduced; meanwhile, due to the fact that the process for machining the vacuum layer on the bottom of the inner liner body is omitted, the product manufacturing time is shortened, namely the product manufacturing efficiency is improved; the product manufacturing cost is further reduced, and the market competitiveness of products is improved.

Description

technical field [0001] The invention relates to the field of electric heating containers, in particular to a liner of a vacuum electric heating container and an electric kettle containing the liner. Background technique [0002] At present, in the prior art, a vacuum connection layer is provided between the bottom of the inner tank and the bottom of the outer tank in the prior art, and the edge of the vacuum layer is sealed and welded to the bottom of the inner tank, and the electric heating device is located between the inner tank and the vacuum tank. Between the connecting layers, although the setting of the vacuum connecting layer increases the heat preservation effect of the vacuum electric kettle, the setting of the vacuum connecting layer also increases the production process steps of the vacuum electric kettle, which increases the difficulty of manufacturing the product, thereby improving The manufacturing cost increases the sales price of the product, the market comp...
