Problems solved by technology

At the same time, it also pointed out the shortcomings of this structure: in order to obtain a screw hole with sufficient strength, the wall thickness will be excessively increased and affect the cost; or the formation of a ring-shaped local protrusion on the outside of the container will affect the injection molding process and product appearance
Although this structure solves the problem of removing the heating element and recycling it when necessary, the structure is complicated and the rigidity is not good

Abstract

The electrically heating container with flat plate heating element includes main container body with conic cavity over the seat, horizontal flat plate heating element inside the container, and support located onto the inner side wall and with outer edge connected to the inner side wall. It features that there are one fixed ring below the heating element along the inner side wall of the container and one fastening block to form complementary structure with container wall, with the seat being fixed to the fixing ring and the heating element. The present invention has the relevant parts constituting stable installation chain easy to be dismounted and the heating element and its born part are supported firmed in high rigidity.

Description

technical field [0001] The invention relates to an electric heating container, in particular to an installation structure in which a flat heating element is attached to the bottom of the inner cavity of a conical electric heating container. In the International Patent Classification, the classification belongs to A47J27 / 21. Background technique [0002] Electric heating containers, including household electric heating appliances such as electric kettles, electric kettles, electric water cups and electric water heaters, and similar laboratory equipment, are more and more used flat heating elements to be attached to the water for aesthetics or ease of cleaning. The structure of the cavity bottom. Also due to aesthetics and other reasons, the inner cavity of many container bodies is designed as a cone. This structure can only install a flat heating element in the inner cavity from bottom to top: first, it is positioned upward on the support part of the inner wall of the contai...
