Background Art

[0002] Conventional table plates and interior decorative plates of campers usually do not have a heating function. The heating wires of conventional heating plates are generally directly adhered between two layers of plates, which are prone to security risks, and the weight of the plates is always heavy.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The present invention solves the problems in the related art and provides a composite heating plate. An alloy wire spiral heating wire is embedded in PET to avoid the occurrence of security risks. Moreover, the middle heating layer adopts PET, which reduces the weight of the whole heating plate, and has relatively good waterproof, heat preservation, and flame retardant effects, and small thermal deformation.

Means for Solving the Problems

[0004] To solve the above technical problems, the present invention is realized by the following technical solutions. It includes a surface decorative layer, a heating layer, and a bottom decorative layer. The heating layer is adhered between the surface decorative layer and the bottom decorative layer. The heating layer includes an alloy wire spiral heating wire and a PET layer. The alloy wire spiral heating wire is embedded in the PET layer, and a power interface is provided on the PET layer.

[0005] Preferably, both the surface decorative layer and the bottom decorative layer are any one of a density board, a PVC board, a rock board, or a solid wood composite decorative board.

[0006] Preferably, the bottom decorative layer is any one of EPS, XPS, or silica gel.

[0007] Preferably, it further includes a temperature controller, which is fitted into the bottom or side of the composite heating plate, and the temperature controller is connected to a power interface and an alloy wire spiral heating wire.

[0008] Preferably, the heating layer is adhered to the surface decorative layer and the bottom decorative layer by a hot melt adhesive or an epoxy resin.

Advantages of the Invention

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows. The present invention inserts an alloy wire spiral heating wire into PET, avoiding the occurrence of security risks. Moreover, the middle heating layer adopts PET, reducing the weight of the entire heating plate, and having relatively good waterproof and flame-retardant effects, with little thermal deformation. Also, since PET itself has closed pores, it has a relatively good heat preservation effect, and heat is only released from the decorative layer of the surface decorative layer, with less heat loss. The decorative layer selects a density board, a PVC board, a rock board, or a solid wood composite decorative board, having the advantages of wear resistance and high temperature resistance. Also, when used as a table board, the bottom decorative layer can select heat insulation materials such as EPS, XPS, and silica gel, thereby achieving the effects of heat insulation, flame retardancy, and moisture prevention.

Modes for Carrying Out the Invention

[0011] The following refers to the drawings in the embodiments of the present invention, clearly and completely explains the technical solutions in the embodiments of the present invention. It is clear that the described embodiments are only some of the embodiments of the present invention, not all of them. The following description of at least one exemplary embodiment is actually exemplary and is not intended as any limitation on the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present invention.

[0012] It should be noted that the terms used here are for the purpose of explaining specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used in this specification, unless specifically stated otherwise in the context, the singular form is intended to include the plural form. Also, when the terms "comprising" and / or "including" are used in this specification, it is understood that the presence of features, steps, operations, devices, components and / or combinations thereof is indicated.

[0013] Unless otherwise specifically described, the relative arrangements of the members and steps described in these embodiments, numerical expressions and numerical values do not limit the scope of the present invention. It should be understood that the dimensions of each part shown in the drawings are not in actual proportional relationship for the convenience of explanation. Although the techniques, methods and devices known to those of ordinary skill in the relevant art may not be examined in detail, in appropriate circumstances, the said techniques, methods and devices should be regarded as part of the permission specification. In all examples shown and examined in this specification, any specific value should be construed as an illustration rather than a limitation. Therefore, other examples of the exemplary embodiments can have different values. Similar reference numerals and letters indicate similar items in the following drawings. Therefore, it should be noted that once an item is defined in the drawings, there is no need to further examine it in the subsequent drawings.

[0014] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional terms such as "front, rear, top, bottom, left, right", "lateral direction, longitudinal direction, vertical, horizontal", and "top, bottom", etc. are generally based on the directions or positional relationships shown in the drawings, and are only for the purpose of facilitating the description and simplification of the present invention. Conversely, if not otherwise explained, these directional terms do not indicate or imply that the indicated device or element must have a specific orientation or be structured and operated in a specific orientation.
