Directional accumulated-heat guiding rice cooker

Abstract

The invention discloses a directional accumulated-heat guiding rice cooker. The rice cooker comprises a heating plate, an inner container, an outer housing and an electric control device, wherein the heating plate comprises a panel shell, heating tubes, a heat accumulation layer and a thermal insulating layer; the heating tubes are clung to the inner surface of the panel shell; the heat accumulation layer and the thermal insulating layer are sequentially arranged under the heating tubes; the inner container comprises a container body made of a metal material and a conducting layer covering the container body; the thermal conductivity of the conducting layer is smaller than that of the container body; the outer housing is provided with an accommodating chamber with a top opening, the heating plate is positioned at the bottom of the accommodating chamber, the bottom of the inner container is in surface contact with the panel shell; a clearance is reserved between the side wall of the inner container and the outer housing so as to prevent the inner container from transmitting heat to the outside to form a thermal insulation mode; the electric control device is used for controlling the heating plate. The rice cooker can effectively improve the utilization ratio of heat, can transmit heat in all directions to solve the problem that rice is cooked incompletely, and has the characteristics of simple structure, low probability of thermal deformation of a plate body and long service life.

Description

【Technical field】 [0001] The invention relates to an electric heating drinking set, in particular to an electric rice cooker with heat storage and directional flow. 【Background technique】 [0002] According to market research and patent retrieval, most of the heating plates of existing electric rice cookers are made of aluminum, with heat pipes fixed under the aluminum plate. The performance is poor, and the loss of heat is not easy to control, resulting in a great waste of heat. Generally, the thermal efficiency can only reach between 45% and 60%. This heating plate is not conducive to the needs of cooking, and has the problems of complex structure, easy deformation when heated, and short service life. [0003] Most of the inner pots of existing electric rice cookers are made of aluminum or iron inner pots, which are made of a single material. The heat is transmitted from the heating plate to the bottom of the inner pot, and then gradually transferred to the upper part o...
