Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1, the heating pan in the present embodiment includes a pan body 1, a control module, and a plurality of heating coils 2.

The disc body 1 is made of a non-heat-conducting material, and the disc body 1 is used for mounting the heating coil 2 and further supporting the heating coil 2. The shape of the tray body 1 is specifically set according to the requirement, and various shapes such as a circle, an ellipse, a rectangle, a triangle, a polygon and the like can be adopted. In order to ensure a heating area capable of covering the object to be heated, the area of the tray body 1 is generally larger than the heating area of the object to be heated.

The plurality of heating coils 2 are arranged on the plate body 1 in a lattice shape, and the heating coils 2 distributed on the plate body 1 have a circular or rectangular outline as a whole according to needs, and in this embodiment, 4 × 4 lattice heating coils 2 are used. Each heating coil 2 is connected with the control module through switch and signal of electricity respectively, and control module can realize the independent on-off control to each heating coil 2 through each switch, so can adjust the quantity and the position of circular telegram heating coil 2 through control module's control, and then reach the regulation of heating position control, power regulation and heating homogeneity.

Specifically, the tray body 1 is provided with openings 11 corresponding to the respective heating coils 2, and the heating coils 2 are fitted in the openings 11. In order to effectively ensure the service life of the plate body 1, a heat insulation layer is arranged between the outer circumferential surface of the heating coil 2 and the inner circumferential surface of the opening 11, so that the mutual influence among the heating coils 2 is small.

As shown in fig. 2 and fig. 3, the present invention also relates to an electric heating range, which comprises an upward-opening chassis 3, a panel 4 covering the chassis 3, and a heating plate as mentioned above, wherein the heating plate is arranged in the chassis 3 facing the panel 4. In order to guarantee the heating effect, the position of heating plate need be close to panel 4, and in this embodiment, the heating plate is close to panel 4 and establishes in panel 4 below, and the edge connection of heating plate has arm brace 6, and the lower extreme of arm brace 6 is connected on the bottom surface of chassis 3. Under the supporting action of the supporting feet 6, the heating plate can be stably close to the panel 4, and then the cooking utensil above the panel 4 is heated.
