Description

Technical Field

[0002] Heated floor heating is an indoor floor heating material that uses flooring as a carrier. It provides heat to the room by embedding heating wires or heating panels in the middle of the floor. For houses using heated floor heating, multiple heated floor units need to be spliced ​​together to form a whole heated floor in the room.

[0003] The wiring process for each heating floor unit, as well as the live and neutral wires, is extremely cumbersome during installation. For example, the wiring for multiple electric heating modules (i.e., heating floor units) disclosed in Chinese patents with application numbers 201811059336X and 2019110792372 requires setting up a neutral and live wire between adjacent rows of heating floor units. Then, one end of the heat-conducting wire of each heating floor unit is connected to the live wire, and the other end is connected to the neutral wire. This is not only cumbersome, but also prone to incorrect wiring due to the close proximity of the neutral and live wires. This could lead to short circuits caused by the live and neutral wires being connected in series during subsequent use, and could even cause a fire.

[0051] It should be noted that the terms "first", "second", and the like in the description and claims of the utility model and the above drawings are used to distinguish like objects, and are not necessarily used to describe a particular sequential or chronological order. It should be understood that the data thus used can be interchanged, where appropriate, so that the embodiments of the utility model described herein can be carried out in other than the order shown or described herein.

[0052] In an embodiment of the utility model, a heating floor unit is provided, referring to Figures 1 to 5 , the heating floor unit comprises a floor unit body 1, as Figure 1 and Figure 2 Indicated, a first wire slot 11, a second wire slot 12 and a third wire slot 13 are arranged on the lower surface of the floor unit body 1, any two of the first wire slot 11, the second wire slot 12 and the third wire slot 13 are not communicated.

[0053] Among them, the first wire slot 11 and the second wire slot 12 are arranged at both sides of the floor unit body 1.

[0054] The first wire slot 11 and the second wire slot 12 are two wire slots, one of which is configured to arrange fire wire 2, and the other is configured to arrange zero line 3.

[0055] The third wire slot 13 is arranged at the middle position of the floor unit body 1, and the third wire slot 13 is configured to arrange heating wire 4.

[0056] As Figure 2 and Figure 3 Indicated, preferably, the first wire slot 11 and the second wire slot 12 are arranged in parallel along the length direction of the floor unit body 1, and the first wire slot 11 and the second wire slot 12 are arranged in parallel along the length direction of the floor unit body 1. The third wire slot 13 is arranged in the middle part of the floor unit body 1 in a plurality of continuous S-shaped bending arrangement. And the two ends of the third wire slot 13 are arranged at the same end of the floor unit body 1 along the arrangement direction of the first wire slot 11 and the second wire slot 12, so as to improve the subsequent wiring efficiency of the heating floor unit.

[0057] The cross-sectional shape of the first wire slot 11, the second wire slot 12 and the third wire slot 13 is set according to the wire cross-sectional shape / requirement, specifically, the cross-sectional shape of the first wire slot 11, the second wire slot 12 and the third wire slot 13 can be a circular arc as shown in Figure 1 The opening width of the circular arc is slightly smaller than the wire diameter, and the diameter of the circular arc is not less than the wire diameter, that is, the jaw width of the first wire slot 11, the second wire slot 12 and the third wire slot 13 is slightly smaller than the wire diameter of the target cable, and the diameter of the cross-sectional circular arc is not less than the wire diameter of the target wire.

In addition, the cross-sectional shape of the first wire slot 11, the second wire slot 12 and the third wire slot 13 can also be rectangular as shown in Figure 4 Or other suitable shapes.

[0058] In an embodiment of the present application, the heating floor unit further comprises a foam plate 5, as shown in Figure 4 And Figure 5 The foam plate 5 is arranged on the lower side of the floor unit body 1.

If the two ends of the heat conductor 4 need to distinguish between connecting the firewire and the zero wire, the first end of the first connector 61 and the second end of the second connector 62 cannot be connected, and the second end of the first connector 61 and the first end of the second connector 62 also cannot be connected.

In addition, by arranging the foam plate below the floor unit body, and the thickness of the foam plate being not less than the height of each connector in the thickness direction of the heating floor unit, the leveling of the heating floor units can be realized by knocking the heating floor units by the leveling hammer / hammer, and each connector is sunken in the foam plate after the heating floor units are laid on the ground, so that the laying efficiency of the heating floor is greatly improved.

[0062] In an embodiment of the present application, a heating floor unit is provided, and the energy-saving performance of the heating floor is further improved.

On the one hand, the heat dissipation performance of the live wire and the zero line can be enhanced, and on the other hand, the heat emitted by the live wire and the zero line can be used for heating.

[0064] In the embodiment, the heat conduction plate 15 can be made of a metal material such as aluminum or an aluminum alloy, or can be made of a carbon crystal material.
