[0048] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0049] Example 1

[0050] See also Figure 2-Figure 3 The dry floor heating insulation board of the present invention comprises:

[0051] A heat-conducting and heat-insulating component 2 is mounted on the aluminum alloy plate 1;

[0052] The heat-conducting and heat-insulating component 2 is composed of a graphene heat-conducting plate 201 and a polystyrene resin heat-insulating plate 202. The graphene heat-conducting plate 201 is arranged below the polystyrene resin heat-insulating plate 202.

[0053] The upper surface of the polystyrene resin insulation board 202 is coated with a graphene thermal conductive coating.

[0054] The aluminum alloy plate 1 installs and fixes the heat-conducting and heat-insulating component 2. The aluminum alloy plate 1 can achieve heat conduction. The heat of the aluminum alloy plate 1 can be conducted upward through the graphene heat-conducting plate 201 and conducted to the polystyrene resin insulation plate 202. The polystyrene resin insulation plate 202 then conducts the heat upward through the graphene heat-conducting coating on its surface, thereby improving the thermal conductivity of the dry floor heating insulation board and the thermal conductivity efficiency. At the same time, under the action of the polystyrene resin insulation plate 202, it can be insulated, so that the heat of the floor evaporates more slowly, and the floor can reach a constant temperature state.

[0055] Example 2

[0056] See also Figures 1-8 The floor heating system for heating the above-mentioned dry floor heating insulation board comprises:

[0057] The paving insulation board 3 is arranged at the bottom of the aluminum alloy board 1, and the paving insulation board 3 is assembled by multiple assembly plates 301, and the upper surface of the paving insulation board 3 is provided with a pipe groove 302; so that it can be convenient for construction workers to assemble, and at the same time, it is also convenient for later disassembly and maintenance.

[0058] The heating pipe 4 is embedded in the pipe groove 302. The two ends of the heating pipe 4 respectively have a pipe water inlet end 401 and a pipe water outlet end 402. The pipe water inlet end 401 and the pipe water outlet end 402 are centrally symmetrical on the heating pipe 4. The pipe water inlet end 401 and the pipe water outlet end 402 extend outward from the pipe groove 302.

[0059] Support columns 5 are fixedly installed at the four corners of the top of the paving insulation board 3. When the aluminum alloy plate 1 is installed above the heating pipe 4, the top of the support column 5 abuts against the bottom of the aluminum alloy plate 1. The four support columns 5 can support the aluminum alloy plate 1 to prevent the aluminum alloy plate 1 from pressing on the heating pipe 4.

[0060] The pipe water inlet end 401 and the pipe water outlet end 402 are connected to the heating mechanism through a heating pipeline.

[0061] The heating mechanism can be connected to the heating pipe 4 through the heating pipeline to form a closed water circulation loop. Through the circulation of hot water, the dry floor heating insulation board connected to the floor heating system can be heated.

[0062] Example 3

[0063] See also Figure 10 The method for controlling the above-mentioned floor heating system comprises the following steps:

[0064] S1. The operator opens the sealing plug of the water filling port 11 and adds water to the hot water tank 9 through the water filling port 11 until the water level is at the upper part of the hot water tank 9 and the water level can cover the copper tube of the electric heating rod 12 and the sensor head of the temperature sensor 16. Then, the water addition is stopped. After the water addition is completed, the sealing plug is re-inserted into the mouth of the water filling port 11;

[0065] S2. The controller 15 has a touch control screen. The operator starts the circulating water pump 8 and the electric heating rod 12 by operating the controller 15. After the electric heating rod 12 is started, it starts to heat the water. After the circulating water pump 8 is started, the water in the hot water tank 9 can pass through the heating pipe and the heating pipe 4 to form a closed loop of circulating flow. After the water in the hot water tank 9 is continuously heated, the water in the closed loop will continuously generate heat. After the hot water passes through the heating pipe 4, its heat can be conducted to the heat-conducting and heat-insulating component 2 through the aluminum alloy plate 1. Under the conduction of the heat-conducting and heat-insulating component 2, the effect of providing geothermal heating to the user is achieved.

[0066] S3. When the electric heating rod 12 continuously heats the water and the temperature of the water is too high, the temperature sensor 16 can monitor the temperature of the water and transmit the monitored temperature to the controller 15. After data analysis and processing, the controller 15 can transmit an electrical signal to the electric heating rod 12 and control the heating temperature of the electric heating rod 12 to gradually reduce the temperature of the water, thereby gradually reducing the temperature of the water circulating in the heating pipe 4. The temperature received by the aluminum alloy plate 1 and the heat-conducting and heat-insulating component 2 also gradually decreases, so that the user gradually feels comfortable.

[0067] When the water temperature is too low, the temperature sensor 16 will monitor the water temperature and transmit the electrical signal to the controller 15. The controller 15 controls the heating temperature of the electric heating rod 12 to gradually increase the water temperature, so that the user feels comfortable.

[0068] This makes it possible to achieve convenient control of the floor heating system.
