Improved structure of electrothermal casserole body

Abstract

The invention discloses an improved pot body structure of an electric-heating earthen pot, comprising a pot body and heating wires, wherein the pot body comprises an upper pot body and a cover connected with the bottom of the upper pot body, the upper end surface of the cover is provided with a groove, the heating wires are embedded in the groove, a heat-conductive filling layer for filling the groove is disposed above the heating wires, and an isolation layer is arranged between the upper end surface of the cover and the bottom of the upper pot body, the isolation layer is made of metal materials excellent in leakage resistance and heat conductivity, additionally, the isolation layer is also provided with a grounding structure, when liquid in the pot leaks out, the liquid can be isolatedby the isolation layer so as to prevent short circuit caused by conduction of the heating wires, thereby the safety of the pot body in use is considerably improved.

Description

Technical field [0001] The invention relates to an improved structure of an electric heating casserole pot body. Background technique [0002] The applicant submitted to the State Intellectual Property Office on March 22, 2007, an invention patent application named an electric heating casserole pot body, the application number is 200720140801.3, such as figure 1 As shown, the heating wire 2 in this patent application is directly embedded in the groove 11 at the bottom of the pot body 1 and then compacted and fixed with the clay 8 mixed with an adhesive. This structure still has a shortcoming, that is The ceramic has a micro air-permeable structure, and the liquid in the pot body with this structure is easy to penetrate down to the heating wire along the air-permeable structure in the pot during use, causing a short circuit and causing danger. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an improved structure of the ele...

[0002] On March 22, 2007, the applicant submitted an application for an invention patent entitled an electric heating casserole body to the State Intellectual Property Office, the application number being 200720140801.3, such as figure 1 As shown, the heating wire 2 in this patent application is directly embedded in the slot 11 at the bottom of the pot body 1 and then compacted and fixed with pottery clay 8 mixed with adhesive. There is still a shortcoming in this structure, that is Ceramics have a slightly air-permeable structure. During the use of the pot with this structure, the liquid in the pot is easy to penetrate downward along the air-permeable structure in the pot to the heating wire, causing a short circuit and causing danger.
