Description

Technical Field

[0001] This utility model relates to the technical field of heating plates, and specifically to a wiring structure for a heating plate. Background Technology

[0002] Currently, electric heating plates, as a common heating element, are widely used in cooking appliances such as rice cookers, electric frying pans, and pressure cookers. To improve heating efficiency and power adjustment flexibility, existing technologies often employ a combination of multiple heating wires to achieve high power output. For example, Chinese patent CN223067213U discloses a high-power electric heating plate that uses a first mica fixing sheet and a second mica fixing sheet, with slots on them. The first and second heating wires are alternately wound in the slots to achieve higher power output and better heating uniformity.

[0003] However, while the patent document mentions that "the two heating wires can be controlled independently," it does not actually disclose the simultaneous operation of the two heating wires. Therefore, to achieve independent or combined operation of the heating wires, it is necessary to provide a novel heating plate wiring structure that can flexibly control multiple heating wires through a simple combination of wiring terminals to meet different power requirements. Utility Model Content

The first and second terminals are respectively electrically connected to the second ends of the two heating wires. By selectively connecting the common terminal to different terminals, heating can be achieved with one or both heating wires. This structure eliminates the need for complex control components, solving the problem of simultaneous operation of two heating wires in existing technologies through a simple combination of three terminals. It allows for flexible adjustment of heating power to adapt to different heating needs, improving the applicability of the heating plate, and simplifies the wiring method.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0024] See Figures 1-7 A heating plate wiring structure includes a heating wire assembly 1 disposed within the heating plate and a power terminal group. The heating wire assembly 1 includes a first heating wire 101 and a second heating wire 102. The power terminal group includes: Common terminal 2, first terminal 3 and second terminal 4, wherein common terminal 2 is electrically connected to the first end of the first heating wire 101 and the second heating wire 102, first terminal 3 is electrically connected to the second end of the first heating wire 101, and second terminal 4 is electrically connected to the second end of the second heating wire 102; When the common terminal 2 is selectively connected to the first terminal 3 or the second terminal 4, the first heating wire 101 or the second heating wire 102 is heated individually. When the common terminal 2 is simultaneously connected to the first terminal 3 and the second terminal 4, the first heating wire 101 and the second heating wire 102 are heated simultaneously.

[0025] The common terminal 2 is electrically connected to the first ends of the first heating wire 101 and the second heating wire 102. The first terminal 3 and the second terminal 4 are electrically connected to the second ends of the two heating wires, respectively. By selectively connecting the common terminal 2 to different terminals, heating can be achieved with one or both heating wires. This structure does not require complex control components. It solves the problem of two heating wires not being able to work simultaneously in the prior art through a simple combination of three terminals. It can flexibly adjust the heating power to adapt to different heating needs, improve the applicability of the heating plate, and the wiring method is simple.

[0026] The heating plate includes a plate body 5 and a decorative cover 6 fixedly connected to the plate body 5. The heating wire assembly 1 and the electrical terminal group are encapsulated between the plate body 5 and the decorative cover 6, and the plate body 5 is filled with a material corresponding to the heating wire assembly 1. The plate body 5 and the decorative cover 6 are fixedly connected, encapsulating the heating wire assembly 1 and the electrical terminal group inside, which can isolate external dust, moisture and other impurities, prevent the components from being corroded, and extend the service life. The filling material is magnesium oxide. Magnesium oxide powder has extremely high electrical insulation strength, preventing current from leaking from the heating wire to the outside of the heating plate. Magnesium oxide is a high-performance thermal conductive material. It can quickly absorb the high-temperature heat generated by the heating wire and transfer it to the outside of the entire heating plate. Moreover, the densely filled magnesium oxide powder can effectively prevent moisture and oxygen in the environment from penetrating to the surface of the heating wire.

[0027] The filling material includes a first filling flour layer 7 and a second filling base powder 8, and the heating wire assembly 1 is located between the first filling flour layer 7 and the second filling base powder 8.

[0028] The two layers of filling material can clamp and fix the heating wire assembly 1 from the top and bottom, making the fixation more stable and preventing the heating wire assembly 1 from shifting; the double-layer structure can more fully wrap the heating wire assembly 1.

[0029] The disc body 5 is provided with a number of vertically extending metal pillars 501. Each metal pillar 501 forms a common end 2, a first terminal 3 and a second terminal 4. The ends of the first heating wire 101 and the second heating wire 102 are respectively electrically connected to the corresponding metal pillar 501.

[0030] The power terminal assembly also includes a fixing base 9 and a plurality of conductive inserts 10 protruding from the fixing base 9. Each conductive insert 10 is arranged in a one-to-one correspondence with each metal post 501, and each metal post 501 is electrically connected to the corresponding conductive insert 10.

[0031] The fixing base 9 is provided with a plurality of fixing holes, and each fixing hole is provided with a metal connector 12. The end of the metal connector 12 protrudes out of the fixing hole and is fixedly connected to the corresponding conductive insert 10. The other end of the metal connector 12 is fixedly connected to the metal post 501, so that the conductive insert 10 and the corresponding metal post 501 are connected to form a conductive connection through the metal connector 12.

[0032] The three metal pillars form three terminals, resulting in lower material costs. By using three terminals, it solves the problem that two heating wires cannot work simultaneously in existing technologies. It can flexibly adjust the heating power to adapt to different heating needs, improve the applicability of the heating plate, and simplify the wiring method, thereby improving enterprise efficiency.

[0033] The decorative cover 6 has an installation clearance position corresponding to the fixing seat 9.

[0034] The outer side of the disc body 5 is provided with a spiral anti-slip texture structure 502.

[0035] The first heating wire 101 and the second heating wire 102 are distributed in inner and outer rings, and the second heating wire 102 is arranged around the outer periphery of the first heating wire 101.

[0036] The first heating wire 101 and the second heating wire 102 are respectively arranged in a spiral structure 13 in the heating plate. The heating power of the first heating wire 101 and the second heating wire 102 may be the same or different.

[0037] The first heating wire 101 and the second heating wire 102 are spirally structured 13, which can increase the effective heating length of the heating wire. The setting of the two with the same or different power further improves the flexibility of power adjustment: when the power is the same, they can work at the same time to output higher power stably and meet the needs of rapid heating; when the power is different, the corresponding heating wire can be used alone or two sets of heating wires can be used at the same time to meet the needs of low power, medium power and high power.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
