[0020] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] Please also refer to Figures 1 to 4 The indoor circulation heating device of the utility model embodiment will be described in detail below with reference to the accompanying drawings.

[0022] The indoor circulation heating device includes a shell 1, wherein a plurality of circulation pipes 2 are arranged inside the shell 1, each of the circulation pipes 2 includes a plurality of vertical pipes 3 and horizontal pipes 4 fixedly connected to both ends of the vertical pipes 3, a flange is fixed between two circulation pipes 2, and the flange is fixed to one end of the horizontal pipe 4, one end of one of the horizontal pipes 4 extends out of the shell 1, and a first solenoid valve 5 is fixed to the end extending out of the shell 1, and the first solenoid valve 5 is connected to an external hot water device away from the end of the horizontal pipe 4, a metal pipe 6 is fixed to the side of the shell 1, and a plurality of metal pipes 6 are equidistantly arranged along the length direction of the shell 1, and all the circulation pipes 2 are connected to a return pipe 7, and one end of the return pipe 7 extends out of the shell 1 to connect to an external hot water device.

[0023] As an implementation manner, a second solenoid valve 8 is connected between the two circulation pipes 2 , and the second solenoid valve 8 is fixed outside the cross pipe 4 .

[0024] A connecting pipe 9 is inserted between the circulation pipe 2 and the return pipe 7 , and a check valve 10 is fixedly connected to the outside of the connecting pipe 9 .

[0025] Furthermore, in specific use, the hot water conduction inside each circulation pipe 2 can be controlled by controlling the opening and closing of the second solenoid valve 8. As shown in the figure, the second solenoid valves 8 are opened from left to right in sequence to achieve the conduction of one circulation pipe 2, two circulation pipes 2, or three circulation pipes 2.

[0026] Specifically, a control board 11 is screwed to the top of the housing 1 , the control board 11 is electrically connected to a power supply 12 , the power supply 12 is mounted on the top of the housing 1 , the power supply 12 is connected to a plug connector 13 , and a control button 14 is embedded on the control board 11 .

[0027] There are a plurality of control buttons 14 , each of which is electrically connected to a second solenoid valve 8 . A switch button 15 is embedded on the control panel 11 , and the switch button 15 is electrically connected to the first solenoid valve 5 .

[0028] First, an external 220V power supply is connected through the plug connector 13, and power is supplied through the power supply 12. The control method is to press the control button 14. After pressing one of the control buttons 14, the two circulation pipes 2 can be connected. At this time, the circulation pipe 2 starts to conduct heat, and the heat is dissipated inside the shell 1. The dissipated heat is conducted to the metal tube 6, and then radiated to the front area of ​​the shell 1.

[0029] The hot water therein flows again to the inside of the return pipe 7 along the connecting pipe 9 at the bottom of the circulation pipe 2, and then flows back to the hot water supply equipment to realize water circulation. At the same time, a check valve 10 is arranged on the connecting pipe 9 to prevent the water in the return pipe 7 from flowing back into the circulation pipe 2.

[0030] As an implementation mode, a heat-insulating cotton board 16 is inserted into the shell 1 on the side facing the metal tube 6 , a groove 17 is provided on the shell 1 , and the groove 17 is arranged along the four corners of the shell 1 , and a plug-in rod 18 is fixed on the heat-insulating cotton board 16 , and the plug-in rod 18 is interference fit with the groove 17 .

[0031] Specifically, during use, in order to avoid the risk of burns caused by overheating of the metal tube 6, a thermal insulation cotton board 16 can be installed on the shell 1 to avoid direct contact with the metal tube 6, while reducing the heat loss rate inside the shell 1. The thermal insulation cotton board 16 is detachable, which is convenient for selection according to actual usage.

[0032] In this embodiment, when the energy-saving heating equipment is in operation, it is connected to the gas wall-mounted boiler, the horizontal pipe 4 extending out of the shell 1 is connected to the water outlet of the gas wall-mounted boiler, and the first solenoid valve 5 is opened by the switch button 15, and hot water enters the circulation pipe 2 for circulation. When the circulation pipe 2 is filled with hot water, the heat energy contained in the hot water begins to dissipate and is conducted to the metal pipe 6, thereby achieving the effect of regulating the indoor temperature.

[0033] The housing 1 provided in the present application can be customized and made into various shapes according to user needs, and the solenoid valve and its control method therein are both existing conventional technologies.

[0034] When the energy-saving heating equipment provided in this application is used for home use, a 25W fan is taken as an example, and a household gas water heater or a wall-mounted boiler is used as a heat source. The theoretical heat dissipation is about 3200W, and the monthly power consumption is about 10.8KW.h, which is about 5.5 yuan / month. Compared with traditional heating equipment, the operating power consumption is greatly reduced.

[0035] When used as a public area, in some occasions, such as office buildings, shopping malls, hotel rooms and other functional rooms that are used according to time periods, the energy consumption during the heating season can be calculated separately according to the fan startup time of the equipment and the power consumption during the heating season. This is more accurate than the traditional charging by area, and at the same time avoids the unreasonable heating fee charges caused by the short use time of some functional rooms, truly realizing the household metering of the heating system in public buildings.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
