[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The purpose of the present invention is to provide a floor heating module to solve the problems of heat waste and complex laying in other current electric heating technologies. By modularizing the existing integral floor heating, a floor heating product with extremely convenient laying, high safety factor and longer service life can be produced.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] Figure 1 This is a side view of a floor heating module according to Embodiment 1 of the present invention. Figure 2 This is a top view of the floor heating module of Example 1 of the present invention. Figure 1 and Figure 2 As shown, the floor heating module of this embodiment includes: a thermal insulation layer 1, a heat conducting layer 2 and a heating element 3. The thermal insulation layer 1 is located at the bottom layer of the floor heating module, the heat conducting layer 2 is located at the upper layer of the floor heating module, and the heat conducting layer 2 is adhered to the thermal insulation layer 1 to form a whole.

[0027] The heat-conducting layer 2 is an aluminum box with grooves made of aluminum plate. The heat-conducting layer in this embodiment includes a plurality of grooves, and the heating element 3 is evenly arranged in the plurality of grooves of the aluminum box, so that heat energy is evenly released from the heat-conducting layer 2, thereby achieving heat energy upward conduction. The first terminal of the heating element 3 is connected to the live wire of the power supply, and the second terminal of the heating element 3 is connected to the neutral wire of the power supply.

[0028] The heat-insulating layer 1 of this embodiment is a polyurethane heat-insulating layer, which is the best heat-insulating material today, so that the heat energy of the heating element 3 is not conducted downward. A heat-conducting aluminum box is made by pressing grooves on the polyurethane heat-insulating layer to form a heat-conducting layer 2. The pressed aluminum box and the polyurethane heat-insulating layer are bonded together by polyurethane foaming technology, so that the heat-insulating layer 1 and the heat-conducting layer 2 are connected as a whole, and the connection is firm and safe.

[0029] In this embodiment, the heating element 3 adopts a carbon fiber heating wire, and the two connection terminals of the heating element are respectively located at the two ends of the floor heating module. The neutral wire and the live wire are separated and connected to the copper wire with gold-plated copper terminals respectively. A single-core male plug is injection molded with woolen cloth and used in conjunction with a single-core female plug with woolen cloth injection molded on the main power line to supply power to the heating element 3.

[0030] The floor heating module of this embodiment can be applied to heating of various floor materials. When dry-laid, in order to improve the heating efficiency, the floor heating module also includes a superconducting film, which is pasted on the upper surface of the heat-conducting layer 2 and located on the top layer of the floor heating module. Carpets, wooden floors, etc. can be directly laid on the floor heating module, which greatly improves the efficiency of heat release on the surface layer and quickly heats up the room.

[0031] When the heating tile is used, the floor heating module and the tile are glued together with polyurethane foam to form the heating tile. The carbon fiber heating wire uses Japanese Toray carbon filaments, and the surface is wrapped with polytetraethylene. The carbon fiber heating wire and the copper wire are connected with gold-plated copper terminals, wool injection molded single-core male heads, and the main power cord is equipped with wool injection molded single-core female heads. When in use, the male and female heads are connected and energized to make the carbon fiber heat up, meeting the needs of electric floor heating.

[0032] In order to improve the utilization rate of energy, the insulation layer 1 is made of flame-retardant polyurethane material, and the insulation effect is best when the thickness is 20mm; the heat-conducting layer 2 is a pure aluminum plate with good thermal conductivity, and the thickness of the aluminum plate is preferably 0.5mm.

[0033] In order to improve the heating efficiency, the heating element 3 uses a carbon fiber heating wire, the length of the carbon fiber heating wire is preferably 12.5m, the diameter is 2.8mm, and double-layer protection is used.

[0034] In order to improve the waterproof performance of the floor heating module, the outer surface of the carbon fiber heating wire is wrapped with a layer of polytetrafluoroethylene, and then covered with flame-retardant PVC to form a protective cover. The hot and cold wire joints of the floor heating module are injection molded with woolen material.

[0035] In order to improve the voltage performance of the heating module, each module must pass the 3750V high voltage test.

[0036] Example 2

[0037] Figure 3 This is a side view of a floor heating module according to Embodiment 2 of the present invention. Figure 4 This is a top view of the floor heating module of Example 2 of the present invention. Figure 3 and Figure 4As shown, the difference between this embodiment and embodiment 1 is that the heat-conducting layer 2 of this embodiment adopts an aluminum box including a groove, and the heating element 3 is evenly arranged in the groove of the aluminum box, and the other parts are the same as the structure of the embodiment. The heating element 3 is connected by a power cord, so that the carbon fiber generates heat energy by Brownian motion. The floor heating module of this embodiment can be dry-laid for heating, or it can be compounded with tiles (800mm×800mm) to form heating tiles for laying heating. When dry-laid, the laying is simple, and multiple floor heating modules are laid on the ground and arranged in parallel on the power cord. When the power is turned on, the heating element inside each floor heating module heats up, and the heat is transferred to the ground by the heat-conducting layer, thereby achieving the setting effect of electric floor heating. When paving heating tiles, it is as convenient as traditional sticky floor tiles. Multiple heating tiles are laid, and connected in parallel with a power cord with a female head. When the power cord is turned on, the heating element inside each heating tile is heated, and the heat is evenly dissipated by the heat-conducting chip and transferred to the tile to release heat energy, thereby achieving the setting effect of electric floor heating.
