Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1 to 4, the electric heating cooker in the embodiment includes a chassis 1, a heating plate 2 disposed in the chassis 1, and a panel 3 covering the chassis 1, and the chassis 1 is further provided with a heat insulating member 4 and a driving mechanism 5 for driving the heat insulating member 4 to rotate.
Specifically, the heating plate 2 includes a plate body 21 and a heating body 22, a plurality of heating regions 211 are circumferentially arranged on the plate body 21 at intervals, the heating body 22 is arranged in the heating regions 211, and the heating body 22 may be arranged on the heating regions 211 in various manners, such as a plurality of arc-shaped heating coils or a plurality of circular heating coils.
The heat insulator 4 is provided above the heating pan 2, the heat insulator 4 changes the area covering the heating area 211 based on the driving rotation of the driving mechanism 5, and the heat insulator 4 may be made of various existing heat insulating materials. By changing the coverage area of the heating area 211, the heat generated by the heating body 22 covered by the cover can not be effectively transmitted to the panel 3, so as to achieve the effect of reducing the heating power. Multiple tests are carried out in the early stage of product development, and then the heating power corresponding to the unit area covered by the heat insulation piece 4 is obtained, so that the driving mechanism 5 can drive the heat insulation piece 4 conveniently.
In order to determine the driving parameters of the heat insulating member 4 by the driving mechanism 5, in the present embodiment, a plurality of sector-shaped heating areas 211 are uniformly and circumferentially spaced on the tray body 21, and a sector-shaped clearance area 212 is formed between adjacent heating areas 211. The heat insulating member 4 correspondingly includes a plurality of blades uniformly arranged along the circumferential direction and connected to each other, and the shape of the blades matches with the shape of the void area 212, so that all the heating areas 211 can be exposed.

In this embodiment, W1= k × W0, where k is a positive integer, and W0 is a unit heating power adjustment amount of the heating pan 2, so that the step power adjustment of the heating pan 2 can be realized based on W0. The specific power regulation range is determined on the basis of the structural characteristics of the fan blades, the interstitial regions 212 and the heating region 211, so that an infinite power regulation within the permissible power regulation range can be achieved for k × W by means of the heat shield 4.
K = [ W/W0] +1 is calculated from the required actual heating power W, where [ ] is the rounded calculation sign, and the fixed heating power W1 provided by the heating plate 2 is calculated from k. If W/W0=0.7, [ W/W0] =0; further, when W/W0=1.4, [ W/W0] =1.
