Multi-segment control coil wire winding structure of electromagnetic heating appliance and electromagnetic heating appliance

Abstract

The invention discloses a multi-segment control coil wire winding structure of an electromagnetic heating appliance and an electromagnetic heating appliance. The multi-segment control coil wire winding structure comprises a top wire-reeling disc assembly, a side wire reeling disc assembly and a bottom wire reeling disc assembly. The bottom wire reeling disc assembly comprises a bottom wire winding support, an R corner wire winding support arranged on the rim of the bottom wire winding support, a bottom coil wound on the bottom wire winding support and an R corner coil wound on the R corner wire winding support. The bottom coil and the R corner coil are controlled by a controller to work independently. The top wire reeling disc assembly comprises a top wire winding support and a top coil wound on the top wire winding support. The side wire reeling disc assembly comprises a side wire winding support and a side coil wound on the side wire winding support. The top coil and the side coil are controlled to work uniformly by the controller. The multi-segment control coil winding structure of the electromagnetic heating appliance and the electromagnetic heating appliance have advantages of accuracy control, uniform heating, high efficiency, long service life, etc.

Description

technical field [0001] The invention relates to a multi-section control coil winding structure of an electromagnetic heating appliance and the electromagnetic heating appliance. Background technique [0002] With the continuous improvement of the level of science and technology, electromagnetic heating appliances are widely used in family life as cooking utensils. Common electromagnetic heaters include electric rice cookers, electric pressure cookers, and electric steamers. Taking the rice cooker as an example, the heating method of the rice cooker in the prior art is single. The electromagnetic coil at the bottom of the rice cooker is wound with a single-segment wire, and only one IGBT is used to control the heating of the bottom and R corner of the inner pot at the same time. The side and top of the rice cooker are designed with heating wires. For heating, the heating wire is controlled by a relay. [0003] There are following defects in this electric cooker: [0004] 1....

AI Technical Summary

Problems solved by technology

[0004] 1. When the electromagnetic coil is working, it heats different positions of the inner pot unevenly, and the quality of the rice is relatively poor;

[0005] 2. The power of the heating wire cannot be adjusted intelligently during the working process, and the use of relay control will shorten the life of the rice cooker;

[0006] 3. The working power of the heating wire is generally about 50W, and the power is relatively small, which does not greatly improve the cooking effect of rice;

[0007] 4. The electromagnetic coil has no structural limit, too many lead-out lines, messy wiring, non-standard, and poor consistency;

[0008] 5. The use of heating wire needs to be in direct contact with the sheet metal parts for heat transfer. Users can directly touch it. There are potential electrical safety hazards and must be grounded.
