Description

Technical Field

[0001] The present invention relates to the technical field of electric heating, and in particular to a heating floor unit, a component and a preparation method thereof. Background Art

[0002] Heating floor is an indoor floor heating material that uses the floor as a carrier. It provides heat to the house by embedding heating wires or heating plates in the middle of the floor. For houses that use heating floor for heating, it is necessary to splice multiple heating floor units on the ground to form an integrated heating floor in the house.

[0003] During the splicing construction of the heating floor units, the wiring operations of each heating floor unit and the live and neutral wires are very cumbersome. For example, the splicing wiring of multiple electric heating modules, i.e., heating floor units, disclosed in Chinese patents with application numbers 201811059336X and 2019110792372 requires setting a neutral wire and a live wire between two adjacent rows of heating floor units, and then connecting one end of the heat conducting wire of each heating floor unit to the live wire and the other end to the neutral wire. Not only is the operation cumbersome, but also, due to the close position of the neutral wire and the live wire, it is easy to make wrong wiring operations during the wiring process, which may also cause the live wire and the neutral wire to be connected in series to cause a short circuit during subsequent use, and even cause a fire.

Compared with the heating floor unit in the prior art, which needs to transfer the heat from the heating wire position to the upper surface of the floor layer by layer, the heat transfer efficiency is effectively improved. In addition, by arranging heat storage materials in the heat conductive plate, heat can be adaptively stored and released, so it has good energy-saving performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0071] In one embodiment of the present invention, a heating floor unit is provided. Figures 1 to 5 The heating floor unit comprises a floor unit body 1, such as Figure 1 and Figure 2 As shown, a first cable groove 11, a second cable groove 12 and a third cable groove 13 are provided on the lower surface of the floor unit body 1, and any two of the first cable groove 11, the second cable groove 12 and the third cable groove 13 are not connected;

[0072] Wherein, the first cable groove 11 and the second cable groove 12 are arranged on both sides of the floor unit body 1;

[0073] The first cable duct 11 and the second cable duct 12 are two cable ducts, one of which is configured to arrange the live wire 2, and the other is configured to arrange the neutral wire 3;

[0074] The third cable groove 13 is disposed in the middle of the floor unit body 1 , and the third cable groove 13 is configured to arrange the heating wires 4 .

[0075] like Figure 2 and Figure 3As shown, preferably, the first cable trough 11 and the second cable trough 12 are arranged in parallel along the length direction of the floor unit body 1; and the first cable trough 11 and the second cable trough 12 both penetrate the floor unit body 1 along the length direction of the floor unit body 1. The third cable trough 13 is arranged in a middle part of the floor unit body 1 in the form of a plurality of continuous S-shaped bends. And both ends of the third cable trough 13 are arranged at the same end of the floor unit body 1 along the arrangement direction of the first cable trough 11 and the second cable trough 12, so as to improve the subsequent wiring efficiency of the heating floor unit.

[0076] The cross-sectional shapes of the first wiring groove 11, the second wiring groove 12 and the third wiring groove 13 are set according to the wiring cross-sectional shape / requirements. Specifically, the cross-sectional shapes of the first wiring groove 11, the second wiring groove 12 and the third wiring groove 13 can be as follows: Figure 1 In the arc shown, the opening width of the arc is slightly smaller than the wire diameter, and the diameter of the arc is not less than the wire diameter, that is, the bayonet widths of the first row of wire troughs 11, the second row of wire troughs 12, and the third row of wire troughs 13 are slightly smaller than the wire diameters of their respective target cables, and the diameters of the cross-sectional arcs are not less than the wire diameters of their respective target wiring. This method does not require glue dispensing during the subsequent wiring process, and the target cable can be directly clamped through the cable trough. In addition, the cross-sectional shapes of the first row of wire troughs 11, the second row of wire troughs 12, and the third row of wire troughs 13 can also be as follows Figure 4 A rectangle is shown, or another suitable shape may be used.

[0077] In one embodiment of the present invention, the heating floor unit further comprises a foam board 5, such as Figure 4 and Figure 5 As shown, the foam board 5 is arranged on the lower side of the floor unit body 1. During the application of the heating floor unit, the live wire 2 and the heating wire 4 are configured to be connected through the first connector 61, and the neutral wire 3 and the heating wire 4 are configured to be connected through the second connector 62; in addition, the live wire 2 between two adjacent heating floor units is configured to be connected through the third connector 63, and the neutral wire 3 between two adjacent heating floor units is configured to be connected through the fourth connector 64. Preferably, the first connector 61, the second connector 62, the third connector 63, and the fourth connector 64 are all waterproof connectors.

[0078] More preferably, the first end of the third connector 63 cannot be connected to the second end of the fourth connector 64, and the second end of the third connector 63 cannot be connected to the first end of the fourth connector 64. Therefore, not only can the live wire and the neutral wire be isolated in space to prevent fooling around, but the risk of misconnection of the live wire and the neutral wire can be completely avoided. If the two ends of the thermal conductor 4 need to distinguish between the live wire and the neutral wire, the first end of the first connector 61 cannot be connected to the second end of the second connector 62, and the second end of the first connector 61 cannot be connected to the first end of the second connector 62. If the two ends of the thermal conductor 4 do not need to distinguish between the live wire and the neutral wire, then preferably, the first connector 61 and the second connector 62 are the same.

[0079] The thickness of the foam board 5 is not less than the height of the first connector 61 in the thickness direction of the heating floor unit; the thickness of the foam board 5 is not less than the height of the second connector 62 in the thickness direction of the heating floor unit; the thickness of the foam board 5 is not less than the height of the third connector 63 in the thickness direction of the heating floor unit; the thickness of the foam board 5 is not less than the height of the fourth connector 64 in the thickness direction of the heating floor unit.

[0080] By setting three unconnected cable ducts on the floor unit body 1 for laying out the live wire, neutral wire and heating wire respectively, and using connectors to connect the live wire, neutral wire and heating wire, it is possible to simplify the wiring and connection operations and improve the wiring efficiency. Moreover, since the live wire and neutral wire are not set in close positions but are set on both sides of the floor unit body, it is possible to avoid incorrect wiring during the wiring process and reduce the risk of short circuit caused by the series connection of the live wire and neutral wire during subsequent use. In addition, by setting a foam board under the floor unit body, and the thickness of the foam board is not less than the height of each connector in the thickness direction of the heating floor unit, after the heating floor unit is laid on the ground, a leveling hammer / hammer is used to strike the heating floor unit so that each connector sinks into the foam board to achieve the leveling of multiple heating floor units, which can greatly improve the laying efficiency of the heating floor.

[0081] In one embodiment of the present invention, a heating floor unit is provided, which further improves the energy-saving performance of the heating floor. Figure 5 As shown, the floor unit body 1 includes a first insulation board 14, a heat conducting board 15 and a second insulation board 16, which are arranged in sequence from top to bottom, and the thermal conductivity of the heat conducting board 15 is greater than the thermal conductivity of the second insulation board 16. The first cable duct 11, the second cable duct 12 and the third cable duct 13 are arranged on the lower surface of the second insulation board 16.

[0082] In this embodiment, a plurality of through holes are distributed along the extension direction of the third wiring groove 13 on the second insulation board 16, and the through holes penetrate from the upper surface of the second insulation board 16 to the third wiring groove 13. A plurality of protrusions 151 are provided on the lower surface of the heat conducting board 15, and the protrusions 151 correspond to the through holes one by one, and the protrusions 151 extend through the through holes to the third wiring groove 13 and contact the heating wires 4 in the third wiring groove 13. In addition, the through holes can also penetrate from the upper surface of the second insulation board 16 to the first wiring groove 11 and the second wiring groove 12 along the extension direction of the first wiring groove 11 and the second wiring groove 12, and the corresponding protrusions pass through these through holes and contact the live wire in the first wiring groove 11 and the neutral wire in the second wiring groove 12, which can enhance the heat dissipation performance of the live wire and the neutral wire on the one hand, and can also use the heat emitted by the live wire and the neutral wire for heating on the other hand.

[0083] In this embodiment, the heat conducting plate 15 may be made of a metal material such as aluminum or aluminum alloy, or may be made of a carbon crystal material.

[0084] More preferably, the heat conducting plate 15 has not only good thermal conductivity but also heat storage performance. The heat conducting plate 15 having both thermal conductivity and heat storage performance can be prepared by the following method: mixing metal wire and heat storage material to prepare heat storage thermal conductive material, and using the heat storage thermal conductive material to press the heat conducting plate 15. Alternatively, laying heat storage material between multiple layers of metal mesh to form a layered heat storage thermal conductive material, and using the layered heat storage thermal conductive material to press the heat conducting plate 15. Among them, the heat storage material is a material that can adaptively store and release heat.

[0085] By extending the protrusions on the heat conduction plate into the cable groove and contacting the heating wire, the heat generated by the heating wire can be quickly transferred to the middle and upper layers of the heating floor. Compared with the heating floor unit in the prior art, which needs to transfer the heat from the heating wire position to the upper surface of the floor layer by layer, the heat transfer efficiency is effectively improved and heat can be adaptively stored, thus having a good energy-saving effect.

[0086] In one embodiment of the present invention, see Figure 3 and Figure 6 As shown, a heating floor assembly is provided, including a heating floor unit as described in any one or more combinations of the above embodiments, and a live wire 2, a neutral wire 3, a heating wire 4, a first connector 61, a second connector 62, a third connector 63 and a fourth connector 64 arranged on the heating floor unit.

[0087] In this embodiment, the live wire 2 and the neutral wire 3 are two power wires, one of which is arranged in the first wire slot 11, and the other is arranged in the second wire slot 12. The heating wire 4 is arranged in the third wire slot 13. One end of the heating wire 4 is electrically connected to the live wire 2, and the other end of the heating wire 4 is electrically connected to the neutral wire 3.

[0088] Specifically, the live wire 2 includes a live wire branch 21, and the live wire branch 21 is connected to one end of the heating wire 4 through a first connector 61.

And through the leveling operation, the first connector 61, the second connector 62, the third connector 63, and the fourth connector 64 in each of the heating floor assemblies are all sunken in the foam board, so that the wiring, wiring, laying and leveling of the heating floor are very simple to operate.
