Pot cover suitable for electromagnetic heating and electric rice cooker with same

Abstract

The invention discloses a pot cover suitable for electromagnetic heating and an electric cooker provided thereof. The pot cover suitable for electromagnetic heating comprises an insulation cover plate, a magnetic conductive layer and a conductive layer. The magnetic conductive layer is arranged on the isolation cover plate and extends along the circumferential direction of the isolation cover plate. The conductive layer is arranged on the insulation cover plate. A loop is formed by serial connection between the conductive layer and the magnetic conductive layer. According to the pot cover suitable for electromagnetic heating, current can circulate along the magnetic conductive layer and the conductive layer when current is generated by induction due to the fact that the magnetic conductive layer and the conductive layer, in serial connection, are adopted. That is to say, through the conductive layer and the magnetic conductive layer, heat can be generated. The positions of the conductive layer and the magnetic conductive layer can be set according to needs so that the pre-set position can be heated. On the condition of reasonably arranging the conductive layer and the magnetic conductive layer, the heating region of the pot cover can be properly broadened.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a pot cover suitable for electromagnetic heating and an electric rice cooker with the same. Background technique [0002] In related technologies, in order to achieve three-dimensional heating, high-end electric cookers often also have heating elements on the upper cover, so as to heat the upper cover and solve the problem of insufficient heating of the surface of the upper layer of rice. IH electromagnetic induction technology is widely used in the auxiliary heating of the upper cover due to its advantages of fast and easy control. However, in order to make the entire upper cover evenly heat, it is often necessary to arrange heating coils for induction on the entire upper cover in a large area, and because the space of the upper cover is limited, the upper cover should also be provided with steam outlets and to deal with the overflow of rice soup. Large-scale induc...

However, in order to make the entire upper cover evenly heat, it is often necessary to arrange heating coils for induction on the entire upper cover in a large area, and because the space of the upper cover is limited, the upper cover should also be provided with steam outlets and to deal with the overflow of rice soup. Large-scale induction heating coils have to be sealed in a wide range, which makes the structure of the upper cover complicated and the cost increases
