Electric oven adopting planar heating body heating technology

Abstract

The invention discloses an electric oven adopting the planar heating body heating technology. The electric oven comprises a cavity inner container, a cavity inner container upper cover, a heating pipe arranged at the top of a cavity and a baking net arranged under the heating pipe; a planar heating body heating plate is arranged under the baking net and comprises a heating plate body; a ceramic insulating coating is arranged on a heating surface of the heating plate body; a planar heating body heating film is arranged on the outer surface of the ceramic insulating coating; conductor coatings are arranged at two ends of the planar heating body heating film; and the conductor coatings are connected with a power supply through wires. Heat can be quickly conducted or radiated to heated food, and the baking temperature of the surface of the baking tray is uniform; the distance of a planar heat source heated by the planar heating body acting on baked food is short, the infrared radiation effect is strong, and the time from heating to temperature stabilization is short, so that the food can be rapidly heated.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an electric oven with planar heating element heating technology. Background technique [0002] Electric ovens are very common in real home life. Existing ovens are heated by infrared radiation generated by heating tubes. The heat sources of the heating tubes are concentrated on the tubes, and the food is heated by thermal radiation. The existing electric oven still has the following disadvantages. The surface temperature of the food heated by the ordinary heating tube is uneven, and the temperature of the plate surface near the heating tube is high; It is long and consumes a lot of energy; the infrared light wave penetrating effect of the heating effect of the heating tube is weak, and the baking process is that the temperature penetrates from the surface to the inside and heats up layer by layer. Contents of the invention [0003] The object of the present invention is to ...

AI Technical Summary

Problems solved by technology

The existing electric oven still has the following disadvantages. The surface temperature of the food heated by ordinary heating pipes is uneven, and the temperature of the plate surface near the heating pipes is high; the heat loss of the heating pipes is large during the temperature conduction process, and the time from the beginning of heating to the temperature stabilization It is long and consumes a lot of energy; the infrared light wave penetration effect of the heating effect of the heating tube is weak, and the baking process is that the temperature permeates from the surface to the inside layer by layer.
