Abstract

This utility model discloses a multi-winding, zoned heating electromagnetic heating plate, including a support and coils. The support includes a central member, connecting members, and an outer ring member arranged sequentially from the inside out. Several connecting members are spaced apart circumferentially around the central member and connected to the central member and the outer ring member, respectively. Several coils are spirally extended circumferentially from the inside out around the central member and wound on the connecting members. These coils are independent of each other and are spaced apart on the connecting members. By arranging several coils on the support, each coil spirally extending circumferentially from the inside out around the central member and wound on the connecting members, and these coils being spaced apart along the length of the connecting members, this utility model ensures that when the coils are energized simultaneously, the strong magnetic region of the outer coil is adjacent to the weak magnetic region of the inner coil in adjacent coils. This results in a more even magnetic field coverage of the multi-winding, zoned heating electromagnetic heating plate, ensuring uniform heating of the wok and excellent cooking results. Furthermore, the independence of the coils allows for flexible cooking methods.

Description

Technical Field

[0001] This utility model relates to the field of electromagnetic heating plate technology, and in particular to a multi-winding group zone heating electromagnetic heating plate. Background Technology

[0002] The electromagnetic heating plate is the core component of electromagnetic heating equipment. It mainly consists of a support and a coil. When alternating current is passed through the coil, it generates an alternating magnetic field, which induces eddy currents in metal objects, causing them to heat up. The alternating magnetic field generated by the coil is strong near the center and weak far from the center, resulting in uneven heating of the metal object (such as a wok) and poor cooking results. Utility Model Content

[0003] The purpose of this invention is to provide a multi-winding, zoned heating electromagnetic heating plate to solve the problem that the magnetic field generated by the existing electromagnetic heating plate is strong in the area near the center of the coil and weak in the area far from the center of the coil, resulting in uneven heating of the heated metal object (such as a wok) and poor cooking effect.

[0004] This utility model is achieved through the following technical solution:

[0005] A multi-winding, zoned heating electromagnetic heating plate includes a support and coils. The support includes a central member, connecting members, and an outer ring member arranged sequentially from the inside out. There are several connecting members, which are spaced apart circumferentially around the central member and connected to the central member and the outer ring member respectively. The coils extend spirally from the inside out around the central member and are wound around the several connecting members. There are several coils, which are independent of each other and are spaced apart along the length of the connecting members.

[0006] Furthermore, the two ends along the length of the coil are defined as free ends, and the free ends adjacent to the adjacent coil are defined as neighboring ends, and the two adjacent ends are connected.

[0007] Furthermore, the central component and the outer ring component are arranged vertically at intervals, with the outer ring component positioned higher and the central component positioned lower. The connecting component is inclined inward from top to bottom, and at least one side of the connecting component facing the coil is an arc-shaped surface.

[0008] Furthermore, the outer ring extends horizontally from the inside out, and reinforcing ribs are provided on both the top and back surfaces of the outer ring.

[0009] Furthermore, the coil is disposed on the top surface of the connector, and a magnetic element is provided on the back side of each connector.

[0010] Furthermore, the connector is provided with a magnetic groove for inserting the magnetic component.

[0011] Furthermore, the central component is provided with a plurality of vertically extending connecting holes, each of the connecting holes corresponding to a plurality of magnetic grooves, and each connecting hole communicating with the corresponding magnetic groove, with the magnetic component portion inserted into the connecting hole.

[0012] Furthermore, the same connector is provided with a plurality of magnetic elements arranged sequentially along its length. Among the plurality of magnetic elements, the magnetic element adjacent to the connecting hole is an L-shaped magnetic element, and the remaining magnetic elements are strip-shaped magnetic elements.

[0013] Furthermore, the connector is provided with a coil slot for inserting the coil.

[0014] Furthermore, the central component, the connecting component, and the outer ring component are integrally formed.

[0015] The advantages of this technical solution lie in the fact that by arranging several coils on the support, each coil spirally extends from the inside out around the central component and is wound around several connecting components. These coils are spaced apart along the length of the connecting components. When the coils are energized simultaneously, the strong magnetic region of the outer coil is adjacent to the weak magnetic region of the inner coil in two adjacent coils. This ensures even magnetic coverage of the multi-wound, zoned heating electromagnetic heating plate, resulting in uniform heating of the metal object (such as a wok) and excellent cooking performance. Furthermore, by configuring the coils independently, the multi-wound, zoned heating electromagnetic heating plate can heat specific areas, allowing for flexible cooking methods.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figure 1-6 As shown, the multi-winding, zoned heating electromagnetic heating plate includes a support 1 and coils 2. The support 1 includes a central member 101, connecting members 102, and an outer ring member 103 arranged sequentially from the inside out. There are several connecting members 102, which are spaced apart circumferentially around the central member 101 and connected to the central member 101 and the outer ring member 103 respectively. The coils 2 are spirally extended circumferentially from the inside out around the central member 101 and wound around the several connecting members 102. There are several coils 2, which are independent of each other and are spaced apart along the length of the connecting members 102. The energization of the several coils 2 is independent of each other. This embodiment provides a multi-winding, zoned heating electromagnetic heating plate to solve the problem of uneven heating of metal objects (such as woks) and poor cooking results caused by the magnetic field generated by existing electromagnetic heating plates being strong near the center of the coil and weak in areas far from the center. The main solution is to arrange several coils 2 on a support 1. Each coil 2 is spirally wound around a central member 101 from the inside out and onto several connecting members 102. The coils 2 are spaced apart along the length of the connecting members 102. When the coils 2 are energized simultaneously, the strong magnetic region of the outer coil 2 is adjacent to the weak magnetic region of the inner coil 2, resulting in a more even magnetic field coverage and more uniform heating of the metal object (such as a wok), leading to better cooking results. Furthermore, by arranging the coils 2 independently, the multi-winding, zoned heating electromagnetic heating plate can heat specific areas, allowing for flexible cooking.

[0026] In this embodiment of the invention, the two ends along the length of the coil 2 are defined as free ends 201. Of the two free ends 201, the free end 201 adjacent to the adjacent coil 2 is defined as the neighboring end 202. In two adjacent coils 2, the two neighboring ends 202 are connected. Specifically, the two neighboring ends 202 are bundled together and used as current input or output terminals. This arrangement simplifies the wiring connections of several coils 2 by configuring the two neighboring ends 202 together as current input or output terminals.

[0027] In this embodiment of the invention, the central member 101 and the outer ring member 103 are arranged vertically at intervals, with the outer ring member 103 positioned higher and the central member 101 positioned lower. The connecting member 102 is inclined inward from top to bottom, and at least one side of the connecting member 102 facing the coil 2 is an arc-shaped surface. This arrangement, by configuring the central member 101 and the outer ring member 103 vertically at intervals and ensuring that at least one side of the connecting member 102 faces the coil 2 is an arc-shaped surface, allows the support 1 to adapt to the shape of the wok and improves the cooking effect.

[0028] In this embodiment of the invention, the outer ring 103 extends horizontally from the inside out, and reinforcing ribs 104 are provided on both the top and back surfaces of the outer ring 103. This arrangement, by configuring the outer ring 103 to extend horizontally from the inside out, ensures stable assembly of the bracket 1, and by providing reinforcing ribs 104 on the outer ring 103, it gives the outer ring 103 good structural strength.

[0029] In this embodiment of the invention, the coil 2 is disposed on the top surface of the connector 102, and the back of each connector 102 is provided with a magnetic element 3. This arrangement, by placing the coil 2 on the top surface of the connector 102 and the magnetic element 3 on the back of the connector 102, reduces electromagnetic leakage and enhances energy efficiency.

[0030] In this embodiment of the invention, the connector 102 is provided with a magnetic groove 105 for inserting the magnetic component 3. This arrangement, by configuring the magnetic groove 105 on the connector 102, ensures stable assembly between the magnetic component 3 and the connector 102.

[0031] In this embodiment of the invention, the central component 101 is provided with a plurality of vertically extending connecting holes 106, each connecting hole 106 corresponding to a plurality of magnetic grooves 105. Each connecting hole 106 communicates with its corresponding magnetic groove 105, and a portion of the magnetic component 3 is inserted into the connecting hole 106. This arrangement, by configuring connecting holes 106 on the central component 101 that communicate with the magnetic grooves 105, and by inserting a portion of the magnetic component 3 into the connecting hole 106, further reduces electromagnetic leakage and enhances energy efficiency.

[0032] In this embodiment of the invention, a plurality of magnetic elements 3 are arranged sequentially along their length on the same connector 102. Among the plurality of magnetic elements 3, the magnetic element 3 adjacent to the connecting hole 106 is an L-shaped magnetic element, and the remaining magnetic elements 3 are strip-shaped magnetic elements. By arranging the magnetic elements 3 into a plurality, with the magnetic element 3 adjacent to the connecting hole 106 being an L-shaped magnetic element and the remaining magnetic elements 3 being strip-shaped magnetic elements, the above arrangement further reduces electromagnetic leakage and enhances energy efficiency.

[0033] In this embodiment of the invention, the connector 102 is provided with a coil slot 107 for inserting the coil 2. This arrangement, by configuring the coil slot 107 on the connector 102, ensures stable assembly between the coil 2 and the connector 102.

[0034] In this embodiment of the invention, the central component 101, the connecting component 102, and the outer ring component 103 are integrally formed. By configuring the central component 101, the connecting component 102, and the outer ring component 103 as an integrally formed component, the bracket 1 has good structural strength.
