Convection conduction type electrical heating device for electric cooker

Abstract

The invention discloses a convection conduction type electrical heating device for an electric cooker. A heating inner container is embedded into an outer container containing cavity of a metal heating outer container, the upper side end of the metal heating outer container is provided with a movable cover body at an opening of the upper end of the outer container containing cavity, a bottom surface thick film heating element is printed on the lower surface of the metal heating outer container, a side wall thick film heating element is printed on the outer surface of the side wall of the metal heating outer container, and a cover body thick film heating element is printed at a middle position of the lower surface of the movable cover body; the novel electric cooker electrical heating device also comprises a controller, and a temperature sensor is arranged on the lower surface of the metal heating outer container; and a food heating chamber is moulded inside the heating inner container, the heating inner container is suspended in the outer container containing cavity, and the outer surface of the heating inner container and the inner wall of the outer container containing cavity are arranged at intervals. The convection conduction type electrical heating device for the electric cooker has the advantages that a safe and nonradiative surround three-dimensional thick film heating way is adopted for heating and cooking food, and the food can be effectively, fully and uniformly heated. Therefore, the convection conduction type electrical heating device for the electric cooker has the advantages of novel structural design, high security and good heating effect.

Description

technical field [0001] The invention relates to the technical field of electric food heating and cooking devices, in particular to a convection conduction electric heating device for an electric rice cooker. Background technique [0002] As a kind of important electric heating cooking device, electric rice cooker is widely used in people's daily life. Among them, for the existing electric rice cooker, it generally adopts the bottom heating method to realize heating. Specifically: the electric rice cooker is equipped with an electromagnetic heating plate on the lower end side of the inner tank. When heating, the inner tank and the electromagnetic heating plate The plate contacts, and the heat generated by the electromagnetic heating plate is conducted to the inner tank after the electric heating plate is energized, and then the food is heated. In addition, the electric rice cooker in the prior art also adopts an infrared heating method to heat food. [0003] However, for th...
