[0002] In home decoration, floor heating floors have been widely used in home heating, warm rooms and other spaces.

[0003] Regarding the above-mentioned related technologies, the inventors believe that there are the following defects: when the heating element is powered on and generates heat, the heat transfer mechanism of the floor heating floor is to first heat up the entire paving base plate, and then transfer heat to the indoor environment through ceramic or solid wood brick panels.

[0040] The following is combined with Figure 1-8 This application is described in further detail.

[0041] The present application embodiment discloses a high heat conduction floor heating floor, such as Figure 1As shown, it includes a paving bottom plate 1, a brick plate body 2 and an electric heating wire 7. The paving bottom plate 1 includes a sealing plate 11 and a base plate 12. The base plate 12 is a rectangular parallelepiped structure with one side open. A base plate extension plate 123 is integrally formed outward at the opening of the base plate 12. The sealing plate 11 is fixedly attached to the base plate extension plate 123. At this time, a grouting chamber is formed between the sealing plate 11 and the base plate 12. The side wall of the base plate 12 is provided with a grouting hole 122 connected to the grouting chamber.

[0042] The brick plate body 2 is square and is arranged on the side of the sealing plate 11 away from the base plate 12. When the brick plate body 2 is made of ceramic material, Figure 1 As shown, the sealing plate 11 is provided with bonding holes 111 penetrating through the thickness thereof, the brick plate body 2 is fitted on the surface of the sealing plate 11, and concrete slurry or adhesive is poured into the grouting chamber through the grouting holes 122. After overflowing from the bonding holes 111, the brick plate body 2 and the sealing plate 11 can be relatively fixed.

[0043] When the brick panel body 2 is made of solid wood material, Figure 2 As shown, the brick board body 2 is directly bonded to the cover plate 11 .

[0044] like Figure 1 As shown, the surface of the sealing plate 11 is concave toward the substrate 12 to form a laying groove 112 and an extension groove 114. If a bonding hole 111 is provided on the sealing plate 11, the laying groove 112 and the extension groove 114 should not interfere with the opening position of the bonding hole 111. The laying groove 112 is an axisymmetric structure, which is formed by connecting a plurality of U-shaped segments end to end; the extension groove 114 has two sections, and the extension grooves 114 are symmetrically arranged along the symmetry axis of the laying groove 112, one end of one of the extension grooves 114 is connected to the head end of the laying groove 112, and one end of the other extension groove 114 is connected to the end of the laying groove 112, and the electric heating wire 7 is buried in the laying groove 112 and the extension groove 114.

[0045] In order to prevent the electric heating wire 7 from being easily separated from the laying groove 112 and the extension groove 114 when laying the floor heating floor, a sealing tape 3 is adhered to the sealing plate 11 to seal the laying groove 112 and the extension groove 114. The sealing tape 3 needs to be made of a material with high thermal conductivity, such as aluminum foil. When the electric heating wire 7 is energized and heated, the sealing tape 3 is not easy to affect the efficiency of heat transfer to the brick board body 2.

[0046] The wiring method of the electric heating wire 7 in the present application is as follows Figure 3 In the specific implementation process, if the laying grooves 112 are all designed to be connected end to end in a number of U-shaped sections, and the ends of the electric heating wires 7 are extended toward the opposite sides of the sealing plate 11, the wiring work is also carried out on both sides of the floor heating floor, such as Figure 4Compared with the above scheme and the scheme of the present application, taking the brick plate body 2 model of 500mm*500mm as an example, the width of a single U-shaped section is 60mm, and the laying length of the electric heating wire 7 in the present application is longer, that is, the present application maximizes the wiring length of the electric heating wire 7 within the limited area of ​​the surface of the paving base plate 1, thereby improving the overall heating effect of the floor heating floor.

[0047] The present application also discloses a floor heating floor paving wiring system, such as Figure 5 As shown, it includes the above-mentioned floor heating floor, and a male plug connector 4 and a female plug connector 5 for wiring.

[0048] like Figure 5 and 6 As shown, a receiving groove 113 is recessed on the middle surface of the sealing plate 11 toward the base plate 12 , and an end of the extension groove 114 away from the laying groove 112 is connected to the receiving groove 113 , and the portion where the extension groove 114 connects with the receiving groove 113 is in an arc transition.

[0049] The male connector 4 is integrally formed with an abutment flange 42 extending away from the center of the male connector 4 at the port of the plug end thereof, and a wiring terminal 45 is integrally injection molded on one side of the male connector 4 away from the plug end thereof, and the wiring terminal 45 is connected to the pin in the plug end of the male connector 4. The opposite outer side wall of the male connector 4 is integrally formed with a plug spring 41, and an abutment space is formed between the plug spring 41 and the abutment flange 42, and a first sealing protrusion 43 is also arranged around the outer side of the male connector 4 in the abutment space. The molding material of the plug spring 41 and the male connector 4 can be PVC, and the molding material of the first sealing protrusion 43 can be silicone, and the first sealing protrusion 43 and the male connector 4 are integrally hot-melt injection molded.

[0050] like Figure 7 As shown, a wiring hole 121 is provided at a position corresponding to the receiving groove 113 on the substrate 12, and one side of the male plug connector 4 provided with the wiring terminal 45 passes through the wiring hole 121 and the bottom of the receiving groove 113 in sequence, until the male plug connector 4 is partially located in the receiving groove 113, but does not exceed the notch of the receiving groove 113. At this time, the bottom of the receiving groove 113 is partially located in the abutment space, one side of the bottom of the receiving groove 113 abuts against the first sealing protrusion 43, and the other side abuts against the substrate 12, and at the same time, the abutment flange 42 abuts against the side of the substrate 12 away from the sealing plate 11.

[0051] like Figure 6 and 7As shown, when the male plug connector 4 is pre-inserted into the receiving groove 113, the ends of the electric heating wire 7 laid in the laying groove 112 and the extension groove 114 can be connected to the ends of the terminal 45 away from the pins in the male plug connector 4. The female plug connector 5 is connected to the power supply of the floor heating temperature control system, and the plug end of the female plug connector 5 is inserted into the pins in the male plug connector 4 to achieve circuit conduction. After the power supply of the floor heating temperature control system is turned on, the electric heating wire 7 can be powered to achieve the heating function. The use of the male plug connector 4 and the female plug connector 5 facilitates the wiring work after the installation of the floor heating floor. At the same time, the male plug connector 4 here can not only realize the power supply and conduction function of the electric heating wire 7, but also can use the abutment space and the first sealing protrusion 43 to firmly press the bottom of the receiving groove 113 and the base plate 12, so as to improve the sealing and leakproof performance at the receiving groove 113 when grouting the base plate 1.

[0052] In the specific implementation process, when the male plug connector 4 is formed, the two ends of the electric heating wire 7 can be directly injection-molded integrally with the male plug connector, and the setting of the terminal block 45 is cancelled, so that the connection between the electric heating wire 7 and the pin in the male plug connector 4 is plastic-coated, which better solves the problem of wiring waterproofing. The specific length of the electric heating wire 7 can be pre-customized according to the length of the laying groove 112 and the extension groove 114.

[0053] In order to facilitate the insertion of the male connector 4 into the receiving groove 113, the side of the plug spring 41 away from the male connector 4 is arranged in a curved surface, and the width of the plug spring 41 gradually decreases along the direction in which the male connector 4 is inserted into the receiving groove 113. The structural characteristics of the plug spring 41 can guide the male connector 4 to be inserted into the receiving groove 113, which is labor-saving and convenient.

[0054] like Figure 8 As shown, the outer side of the female plug connector 5 is also thermoplastically integrally formed with a second sealing protrusion 51 made of silicone material, and no less than two second sealing protrusions 51 are provided along the length direction of the female plug connector 5. In this embodiment, the number of second sealing protrusions 51 is two, and the second sealing protrusions 51 abut against the inner side wall of the male plug connector 4. The provision of the second sealing protrusion 51 can increase the waterproof performance of the connection between the male plug connector 4 and the female plug connector 5, and at the same time increase the stability of the connection between the two.

[0055] like Figure 6 and 7As shown, a cover plate 6 is provided on the sealing plate 11 at the receiving groove 113, a flexible connecting strip 62 is vertically fixed on one side of the cover plate 6, a clamping block 621 is integrally formed at one end of the connecting strip 62 away from the cover plate 6, and a clamping groove 1131 is recessed in the opposite groove wall of the receiving groove 113. The outer wall of the cover plate 6 is also integrally formed with a sealing ring 61 by thermoplastic molding. When the cover plate 6 completely seals the receiving groove 113, the cover plate 6 and the sealing plate 11 are in the same horizontal plane. At this time, the connecting strip 62 is deformed to make the clamping block 621 clamped into the clamping groove 1131. On the one hand, the cover plate 6 is not easy to fall off from the notch of the receiving groove 113, and on the other hand, the sealing ring 61 is squeezed between the side wall of the cover plate 6 and the groove wall of the receiving groove 113, which also increases the sealing and waterproof performance between the cover plate 6 and the receiving groove 113.

[0056] The implementation principle of a floor heating floor paving wiring system in the embodiment of the present application is:

[0057] First, determine the length of the electric heating wire 7 according to the length of the laying groove 112 and the extension groove 114, first connect the electric heating wire 7 to the pin in the male plug connector 4, then insert the male plug connector 4 into the receiving groove 113, so that the bottom of the receiving groove 113 fits with the substrate 12, and then place the electric heating wire 7 in the laying groove 112 and the extension groove 114, and seal the laying groove 112 and the extension groove 114 with the sealing tape 3.

[0058] Next, the cover plate 6 is used to cover the notch of the receiving groove 113, so that the clamping block 621 is clamped with the clamping groove 1131, and the connection between the extension groove 114 and the receiving groove 113 is sealed with glue. The brick body 2 is installed on the surface of the cover plate 11, and then the grouting chamber is grouted. After the grout solidifies, the entire floor heating floor can be used for subsequent direct paving.

[0059] After the floor heating floor is laid on the keel, the male connector 4 is inserted into the female connector 5, and the power cord of the female connector 5 is connected to the entire temperature control system, and the temperature control system can switch on and off the floor heating floor and control the temperature.

[0060] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
