Heating body installing structure of energy-saving mini-sized electric cooker

Abstract

The invention relates to a heating body installing structure of an energy-saving mini-sized electric cooker, comprising an outer pot, an inner container, a cover body and an electric heating body, wherein the inner container is arranged in the outer pot; the electric heating body comprises a heat conducting plate, an electric heating body and an insulation heat conduction layer; a pressing cavity is arranged on the heat conducting plate; the electric heating body is packed by the insulation heat conduction layer; the electric heating body and the insulation heat conduction layer are pressed in the pressing cavity of the heat conducting plate together; a heat conducting face is arranged on the heat conducting plate; the bottom part of the inner container is extended with at least two studs; the part of the heat conducting plate corresponding to every stud is provided with a through hole; the stud is screwed with a nut by penetrating a through hole; and the heat conducting plate is pressed at the bottom part of the inner container by the nut, thus the heat conducting face of the heat conducting plate is clung with the bottom part of the inner container together. As the electric heating body is tightly installed at the bottom part of the inner container by a screwing piece, and with the adoption of the heating body installing structure, the shortcoming that the electric heating body is likely to loose or drop off for using a heat-conducting adhesive, so that the heat can be directly transmitted to the inner container by the heating body, the waste of heat is reduced and the energy-saving effect is realized.

Description

technical field [0001] The invention relates to an electric rice cooker, in particular to a heating body installation structure of an energy-saving miniature electric rice cooker. Background technique [0002] Chinese patent application number CN200910130641.8 disclosed on September 29, 2010 a kind of cooking and heat preservation rice cooker used in automobiles, mainly including a cooker cover top, a cooker cover, a steamer, a cooker shell, a heat preservation lamp LED1, and a cooking lamp LED2 , composed of heat preservation thermostat, the heating plate is in direct contact with the inner pot of the pot, and a jump-type disc-shaped bimetal thermostat assembly is installed in the middle of the heating plate, and the assembly is connected to the control circuit board. In this structure, the heating plate is in direct contact with the inner pot of the pot. In fact, the inner pot of the pot is supported on the heating plate. The heat in the previous part is lost; in addition...

Problems solved by technology

[0006] The installation structure of the heating body of the energy-saving miniature rice cooker includes an outer pot, an inner pot, a cover body and an electric heating body, the inner pot is arranged in the outer pot, the electric heating body includes a heat conducting plate, an electric heating body and an insulating heat conducting layer, and the heat conducting plate A compacting cavity is provided, and the insulating and heat-conducting layer wraps the electric heating body, and they are compressed together in the compacting cavity of the heat-conducting plate. There are two studs, and the heat conduction plate has a through hole corresponding to each stud position. The studs pass through the through hole and are screwed with the nut. Close together; the installation structure of this type of heating body, because the electric heating system is installed close to the bottom of the inner tank through screw joints, overcomes the shortage that the electric heating body is easy to loosen or even fall off due to the use of heat-conducting adhesives, so that The heating body directly transmits heat to the inner tank, reducing heat waste, high thermal efficiency, and achieving energy-saving effects; at the same time, in terms of installation, in view of the fact that the studs are fixed at the bottom of the inner tank, when the electric heating body is fixed, it is directly connected with the nut and The screw connection of the studs is used to tighten the electric heating body to realize the surface contact between the electric heating body and the bottom wall of the inner tank. The installation operation is simple, fast and firm, avoiding the need to wait for the adhesive to dry due to the use of thermally conductive adhesives Only then can the next process be carried out, resulting in low production efficiency.
