Description

Self-heating floor

Technical Field

The utility model relates to the technical field of floor paving materials, in particular to a floor with a self-heating function.

Background

Conventional geothermal floors refer to decorative paving materials that cover floors with geothermal functions. The geothermal function of the ground is generally provided by two modes of water heating and electric heating, but the requirement on the ground environment is relatively high, and the construction engineering quantity is relatively large.

At present, the self-heating floor is a paving material with geothermal function and ground decoration function. In general, a self-heating floor is obtained by compounding an electric heating sheet serving as a heating element with a decorative wood veneer. One form please refer to CN108458398A, the structure of a self-heating floor disclosed in chinese patent application entitled "a self-heating floor and self-heating floor system thereof" comprises a bottom plate and a top plate stacked and adhered, heating cables coiled between the bottom plate and the top plate, and an even number of electrical connectors electrically connected with the heating cables; the surface of the bottom plate facing the top plate is provided with a first accommodating groove at least partially accommodating the heating cable and a second accommodating groove at least partially accommodating the electric connector, and two ends of the second accommodating groove are respectively provided with a first expansion concave part and a second expansion concave part at least partially accommodating terminals at two end parts of the electric connector. Therefore, the heating cable can generate heat after being electrified, and the heat is dissipated indoors through the top plate, so that the geothermal heating effect is achieved. However, since the heating element is directly in contact with the top plate, and the thickness of the top plate is often relatively thin, the temperature difference between the heating cable and the blank area between adjacent heating cables can be sensed more obviously, so that the experience of use is relatively poor. Further, the above-described structure can be applied only to a top sheet composite of a non-wooden material such as a sheet of marble, PVC, or the like. The reason is that the wood veneer has a certain moisture content, and after the wood veneer is compounded, the temperature received by the position corresponding to the installation position of the heating cable on the top plate is higher than that of other areas, so that the moisture in the wood veneer is unevenly distributed, namely the high-temperature area is accumulated to the low-temperature area, and a dark watermark is generated.

Self-heating floors using graphene sheets as heating elements also have the same problems. Graphene is printed on a substrate one by one along the length or width direction, and a blank strip is formed between two adjacent graphene heating strips. The temperature difference which can be obviously sensed is arranged between the graphene heating strips and the blank strips, and the temperature difference can lead to the formation of temperature difference on the wooden veneer which is directly contacted with the graphene sheet, so that the spaced strip watermarks are finally formed.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, shall fall within the scope of the utility model.

Example 1

Referring to fig. 1, the present embodiment provides a self-heating floor board, which includes a heat-generating functional layer 100, a surface layer 200 disposed above and connected to the heat-generating functional layer 100, and a bottom layer disposed below and connected to the heat-generating functional layer. The surface layer and the bottom layer are both wood veneers, for example, the surface layer is a sub-flower pear veneer with the thickness of 2-6 mm, and the bottom layer is a poplar veneer with the thickness of 2-4 mm. Of course, the tree species of the surface layer is not limited to the roseite, the bottom layer is not limited to poplar, and in addition, the surface layer and the bottom layer are not limited to solid wood veneers, and can also be multilayer composite boards, density boards or shaving boards.

In particular, the heat-generating functional layer includes a plurality of filler elements 110, a graphite sheet 120, and a heat-generating element 140. The filler element 110 is generally rectangular and has a degree of elasticity such that the graphite sheet 120 can always abut against both sides of the heating element 140. Preferably, the filler element 110 has a heat-insulating function, for example a polyurethane component. The plurality of filling elements 110 are arranged in parallel with a space between adjacent filling elements 110. Referring to fig. 2, the graphite sheet 120 respectively and continuously covers the side surfaces and the top surfaces of the plurality of filling members 110, and the slots 130 are formed between the cover surfaces of the side surfaces of the adjacent two filling members. By the action of the filling element 110, the two groove walls of the slot 130 always lie against the two webs of the heating element 140. The heating element 140 is a heating cable sheet as shown in fig. 3, or a graphene sheet as shown in fig. 4, both of which are prior art products. The heating element 140 has a heating surface, and two ends have connectors that can be connected to each other or to a power source, which are all conventional, and the connectors are not shown in the drawings. The heating element 140 is vertically inserted in the socket 130. The bottom edge of the heating element 140 is abutted against the bottom of the slot 130, and the top edge is abutted against the surface layer 200. But preferably has a gap 150 between the top edge of the heating element 140 and the skin 200 to ensure that the temperature is conducted only along the two walls of the slot 130 to the portion of the graphite sheet 120 covering the top surface of the filler element 110 and ultimately uniformly to the skin.

The technical solution of the present embodiment is not limited to the arrangement of the filling elements 110. For example, the axial direction of the filler element 110 is perpendicular to the axial direction of the self-heating floor so that a plurality of filler elements 110 are juxtaposed in the length direction of the self-heating floor, which makes it possible to make the length of the circuit relatively short. Of course, a manner is also possible in which the axial direction of the filler element 110 is parallel to the axial direction of the self-heating floor so that a plurality of filler elements 110 are juxtaposed in the width direction of the self-heating floor.

The graphite sheet 120 is first coated with the filling element 110 by hot pressing, and the slot width of the slot 130 formed after coating should be equal to the thickness of the heating element 140. The heat generating element 140 is then inserted into the socket 130, thereby forming the heat generating functional layer 100. Finally, the surface layer 200 and the bottom layer 300 are respectively stuck and connected on the surface and the bottom surface of the heat-generating functional layer 100 through an adhesive.

The self-heating floor of this embodiment can be laid at least by the following method. The paving sequence and method of the self-heating floor of the embodiment are the same as those of the self-heating floor of the prior art, the self-heating floor of the first row is placed at a proper position, and the first side contact of the heating element 140 is connected in parallel to a power supply or a main circuit; placing a second array of self-heating floors in place and correspondingly connecting the first side heating elements 140 to the second side contacts of the heating elements 140 of the first array of self-heating floors; repeating the steps until the paving of all self-heating floors is completed; finally, the second side contact of the heating element 140 of the last row of self-heating floors is closed, as is known in the art. If the distance between the last row of self-heating floors and the wall is greater than 3mm but less than the width of the self-heating floors, then the cut-out conventional floors can be used as the edging.

The self-heating floor of this embodiment can be manufactured at least by the following method. The graphite sheet 120 is first coated with the filling element 110 by hot pressing, and the slot width of the slot 130 formed after coating should be equal to the thickness of the heating element 140.
