[0029] The working principle of an indoor energy-saving heating device provided by the present invention is as follows: when in use, the flat-plate solar collector 6 is installed in a sunny place outdoors, and the insulated water tank 1 is installed indoors. When there is sufficient sunshine during the day, the sunlight heats the water inside the flat-plate solar collector 6. During daytime heating, the controller 7 is regulated, and the controller 7 controls the hot water circulation pump 2 to work. The electric ball valve 2 4 is in the open state, and the electric ball valve 1 3 connects the flat-plate solar collector 6 with the outlet pipe of the hot water circulation pump 2, and then the hot water circulation pump 2 transfers the flat-plate solar collector 6 to the outlet pipe of the hot water circulation pump 2. The water heated in the collector 6 is pumped into the heat pipe 5, and the hot water enters the heat pipe 5 and heats the room through radiation heat dissipation. The water in the heat pipe 5 flows back to the insulated water tank 1. At the same time, the flat-plate solar collector 6 pumps the water in the insulated water tank 1 out through the electric ball valve 24 and the water supply pipe 12, so that the water can circulate outdoors and indoors, and solar energy can be used to heat the room. During the heating process, the temperature sensor 10 detects the water temperature in the insulated water tank 1 and converts the detection result into a telecommunication signal. The signal is transmitted to the controller 7. When the temperature of the insulated water tank 1 is low, the controller 7 controls the electric heating tube 9 to work, and the electric heating tube 9 heats the water inside the insulated water tank 1. At the same time, the electric ball valve 2 4 is closed, and the electric ball valve 1 3 connects the liquid extraction pipe 13 with the insulated water tank 1, and then the hot water circulation pump 2 directly extracts the water inside the insulated water tank 1. The water will not circulate from the flat-plate solar collector 6 to avoid the loss of heat in the water pipeline. During use, the fan 82 can be turned on to blow air forward. The wind body is in the horizontal guide plate 84 and the vertical guide plate 85. The air flow is directed to the surface of the heat dissipation pipe 5, thereby quickly taking away the heat from the surface of the heat dissipation pipe 5, thereby increasing the indoor heating speed. The high heating efficiency improves the comfort of the users, and at the same time avoids long-term preheating, reduces the loss of indoor heat, and has a good energy-saving effect. The wind on the rear side passes through the annular filter 83 through the frustum cover 86 to supplement the rear side of the fan 82. The frustum cover 86 has a guiding effect on the inhaled air, prompting the air to flow along the rear end surface of the guide cover 81, thereby taking away the heat from the rear end of the guide cover 81, and reducing the loss of heat on the rear side.
