Abstract

An electric cooking pot with high heat efficiency belongs to the domestic cooker technology field, including an inner pot body, an electric element for heating the inner pot and a temperature control electric element. The invention is characterized in that the electric element is fixed on the bottom of the inner pot body. The contact surface of the electric element with the lateral wall of the inner pot is sealed. The temperature control electric element is arranged in a sealing cavity under the electric heating element. The invention also provides a heat insulation electric cooking pot, which is equipped with a sealing space between an outer casing and the wall of an inner pot for realizing the sustainable heat preservation with low consumption. The invention solves the problems of the low heat efficiency and the large structural space of the electric cooking pot in the prior art. With the direct contact part contacting with foods on the bottom as the heating surface, the provided electric cooking pot has the advantages of high heat efficiency, small structural space, low production cost, safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of household cooking utensils, in particular to an electric cooking pot. Background technique [0002] In the existing electric cooking utensils, there are mainly three ways to install the inner pot and the electric heating element. The first structure is that the inner pot is separated from the electric heating element, and the inner pot is heated by heat radiation or air convection. The disadvantages of the heating method are low thermal efficiency, long heating time, large structural space, and relatively high cost; the second structure is that the inner pot is set in the outer pot, and the outer pot is equipped with a temperature controller and an electric heating plate, and the electric heating plate is connected to the bottom surface of the inner pot. Contact, if the curvature of the surface of the electric heating plate or the curvature of the bottom of the inner pot is deformed, it will cause abnorma...
