Description

Technical Field

[0001] The utility model relates to the technical field of wall panels, in particular to a wall heating panel with a graphene electric heating film. Background Art

[0002] In the northern part of my country, the winter is long and the temperature is low. In order to survive in the severe cold environment, residents in the north will use heating to increase the indoor temperature. The industrial revolution and the development of energy development and utilization have led to major changes in heating methods, from previous heating methods such as kang heating, fireplace heating, and charcoal brazier heating to coal heating and electric heating. Specifically, coal-fired heating can provide heat for buildings with larger areas. For example, through a centralized heating system, hot water or steam generated by a coal-fired boiler is transported to various buildings through pipes for heating. The widespread use of electricity has led to the birth of a variety of electric heating equipment, such as electric heaters and electric blankets.

[0003] The above-mentioned centralized heating system can increase the indoor temperature faster than electric heating, but it still has some problems. For example, if you want to use centralized heating to increase the indoor temperature, you need to lay heating pipes on the indoor floor during decoration. The heating liquid flows into the dense heating pipes, and the indoor air is heated by conduction through the ground, thereby increasing the indoor temperature. Because the heating pipes are buried in the floor, if they are damaged, it is not conducive to maintenance. In addition, for residents in central my country who are not heated, centralized heating is difficult to achieve.

[0004] Whether in the north or other parts of my country, during the decoration of a house or after the overall decoration of the house, wall panels, i.e. decorative panels, can be installed on the indoor walls to improve the indoor aesthetics. At present, there are many types of decorative panels, such as a decorative panel disclosed in a Chinese patent with publication number CN103874576B, which stacks and integrates a prepreg containing (a) an adhesive component and (b) an endothermic metal hydroxide and a thermosetting resin impregnated decorative paper, wherein in the (a) adhesive component, the mixing ratio of (a1) at least one thermoplastic resin selected from acrylic resin with a glass transition temperature Tg exceeding 0°C, vinyl chloride resin with a glass transition temperature Tg exceeding 0°C, acrylic urethane resin, and waterborne polyurethane resin to (a2) thermosetting resin is 1:0-0.5 in terms of solid content.

[0005] Whether it is the decorative panel disclosed in the above patent or other types of decorative panels, they do not have a heating function. If a heatable decorative panel can be manufactured and applied to the wall, the indoor temperature can be quickly increased by laying such decorative panels over a large area. At the same time, it can be easily disassembled, repaired or replaced according to needs. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0030] Example 1

[0031] like Figure 1-3 As shown, in order to change the current situation where the heating pipes of the central heating system are buried in the floor, which is inconvenient for later maintenance, and to quickly increase the indoor temperature, this embodiment provides a new decorative wall panel that can generate heat after being powered on, thereby heating the indoor gas and achieving indoor temperature increase.

[0032] Specifically, the decorative wallboard includes a base plate 1, a heat insulation layer 121, a graphene heating film 122, and a surface film layer 123. The base plate 1 is set as a gypsum board. The heat insulation layer 121 is directly applied to the base plate 1, the graphene heating film 122 is set above the heat insulation layer 121, the heat insulation layer 121 is pressed and connected with the graphene heating film 122, and the surface film layer 123 is set above the graphene heating film 122.

[0033] The heat insulation layer 121, the graphene heating film 122 and the surface film layer 123 constitute the heating component 12. An interface 13 is provided at the edge of the heating component 12. The interface 13 is electrically connected to the graphene heating film 122. Therefore, it can be connected to a power source through the interface 13, so that current is passed through the graphene heating film 122 to generate heat. The heating principle of graphene is that under the action of the electric field, the carbon atom groups in the heating body undergo "Brownian motion", and violent friction and collision occur between the carbon atoms. The generated heat energy is transmitted in the form of far-infrared radiation, and the conversion rate of electrical energy to thermal energy is as high as more than 96%, and almost no waste is generated. Moreover, the graphene heating speed is very fast. It directly acts on the surface of the object through far-infrared radiation, so that the object heats up rapidly, overcoming the disadvantages of discontinuous and uneven heating of traditional heating products.

[0034] When the graphene heating film 122 is working, the presence of the heat insulation layer 121 reduces the heat transfer to the base plate 1 .

[0035] Example 2

[0036] like Figure 1-3As shown, in order to change the current situation where the heating pipes of the central heating system are buried in the floor, which is inconvenient for later maintenance, and to quickly increase the indoor temperature, this embodiment provides a new decorative wall panel that can generate heat after being powered on, thereby heating the indoor gas and achieving indoor temperature increase.

[0037] Specifically, the decorative wallboard includes a base plate 1, a heat insulation layer 121, a graphene heating film 122, and a surface film layer 123. The base plate 1 is set as a gypsum board. The heat insulation layer 121 is directly applied to the base plate 1, the graphene heating film 122 is set above the heat insulation layer 121, the heat insulation layer 121 is pressed and connected with the graphene heating film 122, and the surface film layer 123 is set above the graphene heating film 122.

[0038] The heat insulation layer 121, the graphene heating film 122 and the surface film layer 123 constitute the heating component 12. An interface 13 is provided at the edge of the heating component 12. The interface 13 is electrically connected to the graphene heating film 122. Therefore, it can be connected to a power source through the interface 13, so that current is passed through the graphene heating film 122 to generate heat. The heating principle of graphene is that under the action of the electric field, the carbon atom groups in the heating body undergo "Brownian motion", and violent friction and collision occur between the carbon atoms. The generated heat energy is transmitted in the form of far-infrared radiation, and the conversion rate of electrical energy to thermal energy is as high as more than 96%, and almost no waste is generated. Moreover, the graphene heating speed is very fast. It directly acts on the surface of the object through far-infrared radiation, so that the object heats up rapidly, overcoming the disadvantages of discontinuous and uneven heating of traditional heating products.

[0039] When the graphene heating film 122 is working, the presence of the heat insulation layer 121 reduces the heat transfer to the base plate 1 .

[0040] like Figure 4-9 As shown, in order to make the decorative wall panel installed on the wall stably and relatively vertically, a support component 2 is set between adjacent base layers 1. The support component 2 can be operated by the staff to change its own state, that is, before the decorative wall panel is installed, the support component 2 is first installed on the wall, and the state of the support component 2 is adjusted according to needs.

[0041] Specifically, the support assembly 2 includes a pressing plate 21, a plurality of brackets 22 and a plurality of middle pieces 23. The plurality of middle pieces 23 are matched with the plurality of brackets 22 one by one, and the middle pieces 23 are adjustable above the brackets 22. The pressing plate 21 is arranged across the plurality of middle pieces 23. Since the middle pieces 23 are adjustable, the state of the middle pieces 23 can be adjusted according to the needs, and then the inclination of the pressing plate 21 can be adjusted, so as to facilitate the stable placement of the decorative wallboard. At the same time, a step groove 11 is arranged at the edge of the base plate 1, and the middle piece 23 is arranged in the space formed by the adjacent step grooves 11. Therefore, under the action of the middle piece 23, the base plate 1 is controlled to be stably placed relative to the wall, and at the same time, the pressing plate 21 fills the gap formed by the step groove 11, which plays a role in aesthetics.

[0042] In order to adjust the state of the middle piece 23 according to the demand, the bracket 22 includes a bottom plate 221, a top plate 222 and a plurality of diagonal bracing plates 225. A through hole is provided at the end corner of the bottom plate 221, and the through hole can be penetrated by an expansion bolt, etc., so that the bottom plate 221 can be fastened and installed on the wall by the action of the expansion bolt. The top plate 222 is arranged on the side of the bottom plate 221, and connecting plates 223 are arranged at both ends of the lower side of the top plate 222, and strip holes 224 are arranged on the connecting plates 223, and the strip holes 224 are arranged along the length direction of the connecting plates 223. At least four diagonal bracing plates 225 are provided, and the four diagonal bracing plates 225 are divided into two groups. The diagonal bracing plates 225 of each group are matched with two connecting plates 223 one by one, and the two groups of diagonal bracing plates 225 are symmetrically arranged. The bottom of the diagonal support plate 225 is hingedly connected to the bottom plate 221, and a bolt is provided through the top of one diagonal support plate 225, the bolt passes through the strip hole 224, and the end thread is inserted into another diagonal support plate 225 in the same group. Therefore, under the action of the bolt, the two diagonal support plates 225 can be forced to approach each other and clamp the connecting plate 223, so that the diagonal support plate 225 is stably placed relative to the top plate 222 and the bottom plate 221, and at the same time, it provides support for adjusting the inclination angle of the diagonal support plate 225 according to needs, thereby adjusting the inclination of the top plate 222.

[0043] In order to stably install the middle piece 23 on the bracket 22, a first protrusion is set on the top of the top plate 222, and a second protrusion is set on the bottom of the middle piece 23. The middle piece 23 is installed on the top plate 222 by bolts, and the first protrusion extends into the gap between the two second protrusions. Therefore, with the cooperation of the bolts and the protrusions, the middle piece 23 is stably installed on the bracket 22.

[0044] In order to stably and detachably mount the pressing plate 21 on the middleware 23, the middleware 23 is arranged in a U-shaped structure with an upward opening, and a clamping groove 231 is arranged on the inner side wall of the middleware 23. The clamping groove 231 is arranged along the length direction of the middleware 23, and both ends are arranged as openings. An elastic plate 211 is fixedly arranged below the pressing plate 21, and a convex column 212 is fixedly arranged on the side wall of the elastic plate 211. The elastic plate 211 extends into the middleware 23, and the convex column 212 is arranged in the clamping groove 231. Therefore, with the cooperation of the convex column 212 and the clamping groove 231, the pressing plate 21 is stably mounted on the middleware 23, and at the same time, the gap formed by adjacent base plates 1 is filled. In addition, under the action of a relatively large external force, the pressing plate 21 can be controlled to be separated from the middleware 23, which facilitates the disassembly of the base plate 1.

[0045] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
