[0045] The present application provides a heat pump heating system, which improves the main temperature adjusting means in the life, generally selects air conditioner or electric heater in the disaster relief tent. The former is mostly assembled by two devices of indoor unit and outdoor unit, has large installation volume, high price, high power consumption and high power consumption. The latter has poor comfort, and is easy to make the air in the disaster relief tent too dry and easy to produce static electricity.

[0046] The technical scheme of the present application is to improve the above technical problems, and the general idea is as follows: the air is sucked into the shell by the fresh air system, so that the heat energy in the air can be absorbed by the heat pump and high temperature is generated under the action of the compressor 2 to heat the water in the water tank 15; under the action of the water wheel 16 in the water heating system, the hot water is driven out of the water tank 15 into the curved pipe 18 to complete the release of heat, and the released heat can heat the air inside the shell, so as to finally realize the purpose of blowing warm air out of the shell for heating.

[0047] In order to better understand the above technical scheme, the above technical scheme will be described in detail in combination with the drawings and specific embodiments of the specification;

[0048] The present application provides a kind of heat pump heating system, including evaporator 1, compressor 2, condenser 3 and expansion valve formed by pipeline and communicated in closed loop, further comprising:

[0049] Upper shell 4 and lower shell 5, the upper shell 4 is located above lower shell 5 and the cavity is formed in the two shells inside;

[0050] Fresh air system, the fresh air system is located in the chamber, for driving the directional flow of air inside the chamber;

[0051] Water heating system, the water heating system is located at the bottom end of the chamber, for heating the air inside the chamber;

[0052] The upper shell 4 is located above the lower shell 5 and is fixedly connected between the upper shell 4 and the lower shell 5 by screw thread, other non-permanent fixed connection mode can also be used, such as bolt connection mode, the cavity is formed inside after the upper shell 4 and the lower shell 5 are closed, the fresh air system inside the chamber will start to work after the device is powered on, and the air inside the chamber is driven to flow directionally, that is, when the air outside is sucked into the chamber under the action of the fresh air system, the low heat in the air is captured by the refrigerant in the evaporator 1 (the refrigerant can be selected as freon-12), and the heat value is amplified by the compressor 2, and then passes through the condenser 3 and the expansion valve in turn to realize continuous heating of the water heating system, the water heating system can form internal circulation in the chamber, and the water is used as heat transfer medium to continuously heat the air inside the chamber, and finally the heated air is blown out of the chamber under the action of the fresh air system, to realize the purpose of blowing warm air for heating of the present application;

[0053] Compared with life, air conditioner or electric heater is usually selected as the main temperature adjusting means in medical shelter and disaster relief tent, the former is mostly assembled by two devices of indoor unit and outdoor unit, has large installation volume, high price, high power consumption and high power consumption, and the latter has poor comfort, and is easy to make the air in the disaster relief tent too dry, and easy to produce static electricity.

[0054] The application integrates important components such as the evaporator 1, the compressor 2 and the condenser 3 into the shell by the combination of the upper shell 4 and the lower shell 5, thereby saving the installation time, transportation cost and space occupied by the outdoor unit in the early stage of using the air conditioner for heating, and providing the heat source by the heat pump in the integrated design, circulating the hot water in the shell through the pipeline to release heat, thereby heating the air in the shell to achieve the purpose of blowing warm air for heating, and meeting the requirements of rapid transportation and installation, convenient use and low supporting cost of the heating equipment when the disaster relief tent is deployed on a large scale.

[0055] As an embodiment of the application, the fresh air system comprises:

[0056] a main impeller 6 rotatably installed in the lower shell 5;

[0057] a double-shaft motor 7 vertically installed in the upper shell 4 and having a lower end output shaft fixed to an upper end of the main impeller 6;

[0058] a fan 8 fixed to the upper end output shaft of the double-shaft motor 7;

[0059] an air inlet channel 9 horizontally located in the lower shell 5 and having one end located behind the main impeller 6 and the other end located on the side wall of the lower shell 5; a plurality of first filter holes 10 are formed in the side wall of the lower shell 5 corresponding to the air inlet channel 9;

[0060] The fresh air system realizes air exchange in the upper shell 4 and the lower shell 5 respectively;

[0061] Air exchange process in the upper shell 4:

[0062] The double-shaft motor 7 is located in the upper shell 4 and fixedly connected to the upper end of the lower shell 5. After being powered, the upper end output shaft of the double-shaft motor 7 drives the fan 8 fixedly connected to the upper end output shaft of the double-shaft motor 7 to rotate in the upper shell 4. The rotating fan 8 generates negative pressure to suck the air at the top of the outside of the upper shell 4 into the upper shell 4. The air sucked into the upper shell 4 is discharged to the outside of the upper shell 4 through the corresponding holes, thereby completing the air exchange in the upper shell 4. Under the action of the fan 8, the air continuously flowing in one direction in the upper shell 4 effectively ensures that the low heat carried by the air can be continuously captured by the evaporator 1, thereby ensuring the continuous heat source supply of the water heating system in the later stage;

[0063] Air exchange process in the lower shell 5:

[0064] The double-shaft motor 7 is located in the upper shell 4 and is fixedly connected with the upper end of the lower shell 5, and the vertically arranged double-shaft motor 7 drives the main impeller 6 fixedly connected with the lower end output shaft of the double-shaft motor 7 to rotate in the lower shell 5 after being powered on. In addition, the lower shell 5 is internally transversely fixedly provided with an air inlet channel 9, one end of the air inlet channel 9 is open at the rear of the main impeller 6, and the other end is open on the side wall of the lower shell 5 and is welded with the side wall of the lower shell 5, and meanwhile, a plurality of first filter holes 10 are formed in the side wall of the lower shell 5 corresponding to the air inlet channel 9.

[0065] When the main impeller 6 rotatably arranged in the lower shell 5 continuously rotates in the lower shell 5 under the driving of the double-shaft motor 7, the rotating main impeller 6 generates negative pressure in the lower shell 5, and the negative pressure causes the air outside the rear side of the lower shell 5 to enter the main impeller 6 from the rear of the main impeller 6 through the first filter hole 10 and the air inlet channel 9, and along the air inlet channel 9. With the continuous rotation of the main impeller 6, the air behind the main impeller 6 is dispersed and blown out of the front end of the lower shell 5 along the rotation direction of the main impeller 6, thereby completing the air exchange in the lower shell 5.

[0066] Under the action of the main impeller 6, the air that continuously flows in one direction in the lower shell 5 can be gradually heated into hot air at the front end and the rear end of the main impeller 6 during the heating process of the water heating system, and finally blown out of the lower shell 5, realizing the heating and warming of the human body surface and the surrounding environment.

[0067] The present application realizes the directional flow of air in the upper shell 4 and the lower shell 5 by driving a double-shaft motor 7, effectively ensuring that there is a continuous supply of low-heat air in the upper shell 4 and that hot air in the lower shell 5 is continuously blown out. In addition, the setting of the first filter hole 10 can effectively reduce the volume of impurities (such as paper, cotton balls, etc.) in the air that is sucked into the lower shell 5 by the main impeller 6, ensuring the cleanliness of the lower shell 5 and reducing the difficulty of later maintenance.

[0068] As an embodiment of the present application, the lower shell 5 is transversely provided with a first sealing plate 11 at the top end, longitudinally provided with a second sealing plate 12 in the lower shell 5, and a third sealing plate 13 is flush with the upper surface of the air inlet channel 9 inside the lower shell 5; the lower end of the lower shell 5 is provided with a fourth sealing plate 14;

[0069] As an embodiment of the present application, the water heating system comprises:

[0070] The water tank 15 is composed of a closed space formed by the outer wall of the air inlet channel 9, the second sealing plate 12, the third sealing plate 13, the fourth sealing plate 14, the bottom end of the lower shell 5 and the side wall of the lower shell 5;

[0071] The evaporator 1 is spirally arranged in the upper shell 4, and a plurality of second filter holes 26 are formed in the top end of the upper shell 4; the compressor 2 is arranged above the third sealing plate 13; the condenser 3 is arranged below the third sealing plate 13; and the expansion valve is arranged on the pipeline between the condenser 3 and the evaporator 1;

[0072] The water wheel 16 is arranged in the water tank 15 and fixed to the bottom end of the main impeller 6;

[0073] The water inlet 17 is arranged on the fourth sealing plate 14 and located at the bottom end of one side of the water wheel 16;

[0074] The curved pipe 18 is arranged at the front end of the main impeller 6 and communicated with the water inlet 17 through a pipeline at one end, and communicated with the water tank 15 through a pipeline at the other end;

[0075] The first sealing plate 11 is horizontally fixed to the top end of the side wall of the lower shell 5, and the upper shell 4 and the lower shell 5 are separated into upper and lower two parts after being closed, so that the gases with different flow directions generated by the fresh air system in the upper shell 4 and the lower shell 5 do not interfere with each other, and the double-shaft motor 7 is fixed to the first sealing plate 11 during installation;

[0076] The second sealing plate 12 is longitudinally fixed to the inner side wall of the lower shell 5, and the inner space of the lower shell 5 is longitudinally divided into two parts by the second sealing plate 12, one part is rotatably arranged with the main impeller 6, and the other part is the main part of the water tank 15;

[0077] The third sealing plate 13 is fixed and arranged flush with the outer upper surface of the air inlet channel 9 on the inner side wall of the lower shell 5, that is, a part of the third sealing plate 13 coincides with the upper end of the outer wall of the air inlet channel 9, and the third sealing plate 13 is not only the top of the water tank 15 but also has the compressor 2 fixed and arranged on the upper surface and the condenser 3 fixed and arranged on the lower surface;

[0078] The fourth sealing plate 14 is fixed and arranged on the lower end of the inner side wall of the lower shell 5, the lower end of the main impeller 6 penetrates through the fourth sealing plate 14 and is rotatably connected with the fourth sealing plate 14, thereby providing bottom support for the rotation of the main impeller 6 in the lower shell 5, in addition, the main impeller 6 penetrating through the fourth sealing plate 14 is fixedly connected with the water wheel 16 at the bottom of the water tank 15;

[0079] The water tank 15 is composed of the closed space formed by the outer wall of the air inlet channel 9 (except the top end), the second sealing plate 12, the third sealing plate 13, the fourth sealing plate 14, the bottom end of the lower shell 5 and the side wall of the lower shell 5, and the whole water tank 15 is in the shape of “L”;

[0080] Before the device is started, water is first injected into the water tank 15, and the maximum height of the water body should be two-thirds of the height of the water tank 15;

[0081] When the device is started, the double-shaft motor 7 and the compressor 2 are powered on, the upper end output shaft of the double-shaft motor 7 drives the fan 8 fixedly connected with the upper end output shaft of the double-shaft motor 7 to rotate in the upper shell 4, the rotating fan 8 generates negative pressure to suck the air outside the top of the upper shell 4 into the upper shell 4 through the plurality of second filter holes 26 on the top surface of the upper shell 4, the air entering the inside of the upper shell 4 first contacts the outer surface of the evaporator 1 fixedly connected with the side wall of the upper shell 4, and the spiral evaporator 1 can maximize the contact area between the outer surface of the evaporator 1 and the air;

[0082] The evaporator 1 is filled with low-boiling liquid refrigerant, when the low heat in the air contacts the surface of the evaporator 1 and heat transfer occurs, the liquid refrigerant will be vaporized by absorbing the low heat from the air, that is, from liquid to gas, the gaseous refrigerant will enter the compressor 2 fixedly installed on the upper surface of the third sealing plate 13 through the pipeline under the suction stroke of the compressor 2, the gaseous refrigerant is compressed by the compressor 2 and changes from low temperature and low pressure to high temperature and high pressure, and then continues to pass through the pipeline to reach the condenser 3 fixedly installed on the lower surface of the third sealing plate 13, the condenser 3 is also spiral and located in the water tank 15, at this time, the high-temperature and high-pressure gaseous refrigerant will release heat through the outer wall of the condenser 3 to the water in the water tank 15 in close contact with the outer wall of the condenser 3, thereby heating the water, the high-temperature and high-pressure gaseous refrigerant is condensed into a gas-liquid mixture after releasing heat in the condenser 3, and finally becomes liquid refrigerant after being throttled and depressurized by the expansion valve, and then returns to the evaporator 1 at the top of the upper shell 4 through the pipeline, and the above process is repeated, and the above process is repeated continuously with the continuous rotation of the fan 8, thereby completing the continuous heating process of the water in the water tank 15;

[0083] At the same time, the lower end output shaft of the double-shaft motor 7 drives the main impeller 6 fixedly connected with the lower end output shaft of the double-shaft motor 7 to rotate in the lower shell 5, the rotating main impeller 6 drives the water wheel 16 fixedly connected with the bottom end of the main impeller 6 to rotate synchronously, the water wheel 16 is located at the bottom of the water tank 15, so during the rotation of the water wheel 16, on the one hand, it can stir the water in the water tank 15 from the bottom of the water tank 15, so that the heat released by the condenser 3 in the water tank 15 can be uniformly absorbed by the water, on the other hand, it can push the water flow at the bottom to the water inlet 17 fixedly installed on the lower surface of the fourth sealing plate 14 in the direction of rotation of the water wheel 16, the water inlet 17 is a rectangular parallelepiped and has a hole inside, which is convenient for the water flow to enter, since one end of the water inlet 17 is communicated with the curved pipe 18 through the pipeline, therefore, the water flow at the bottom of the water tank 15 will enter the curved pipe 18 through the water inlet 17 and the pipeline under the action of the water wheel 16, and will continue to flow along the curved pipe 18 under the continuous pushing of the water wheel 16, until it returns to the upper end of the water tank 15 through the pipeline at the upper end of the lower shell 5 from the other end of the curved pipe 18.

[0084] With the water body in the water tank 15 being continuously heated, the water body in the water tank 15 can be heated to a temperature of 75-85 degrees Celsius at the highest, and the steam generated by the hot water can heat the outer wall of the air inlet channel 9 at the top end of the water tank 15 (except the top end of the outer wall), so that the air can be preliminarily heated by the air inlet channel 9 when passing through the air inlet channel 9 by heat transfer with the hole wall of the air inlet channel 9, and the air can be preliminarily heated by the main impeller 6 at the rear end of the main impeller 6;

[0085] As can be seen from the above process, when the water body in the water tank 15 is heated, the hot water can be transported to the curved pipe 18 as the water wheel 16 rotates, and the curved pipe 18 is in the shape of "Z", so that the hot water in the curved pipe 18 can also release heat to the air in the lower shell 5 by the pipe wall of the curved pipe 18, and the air can be further heated;

[0086] Therefore, under the action of the main impeller 6, the air outside the lower shell 5 at the rear side can be preliminarily heated at the air inlet channel 9 when passing through the air inlet channel 9 from the main impeller 6 at the rear of the main impeller 6, and the air can be further heated at the curved pipe 18 fixedly installed in front of the main impeller 6, so that the heating efficiency of the water heating system on the air is improved;

[0087] The heated air can pass through the curved pipe 18 and the side wall at the front end of the lower shell 5 under the continuous rotation of the main impeller 6, and blow out of the lower shell 5, so as to finally realize the heating of the skin surface of the human body and the surrounding environment.

[0088] As an embodiment of the present application, a plurality of ventilation grooves 19 are formed in the side wall of the upper shell 4; a plurality of ventilation holes 20 are formed in the surface of the first sealing plate 11 corresponding to the compressor 2; a heat dissipation groove 21 is formed in the side wall of the lower shell 5 corresponding to the compressor 2; and a wind collecting cover 27 is fixedly installed on the lower shell 5 outside the ventilation grooves 19 and the heat dissipation groove 21;

[0089] In the upper shell 4, the air sucked into the upper shell 4 by the fan 8 passes through the evaporator 1, and the temperature of the air flow after passing through the evaporator 1 is reduced due to the heat absorption of the vaporization of the refrigerant in the evaporator 1, so that the air after being cooled can be blown to the surface of the compressor 2 through the plurality of ventilation holes 20 formed in the surface of the first sealing plate 11 corresponding to the compressor 2 under the action of the back force of the fan 8, so as to realize the air cooling of the surface of the compressor 2 and prolong the service life of the compressor 2, and the air blown to the surface of the compressor 2 can be blown out of the lower shell 5 through the heat dissipation groove 21 formed in the side wall of the lower shell 5 corresponding to the compressor 2 after taking away the heat of the surface of the compressor 2;

[0090] In order to prevent the ventilation holes 20 from failing to meet the air exhaust demand of the inside of the upper shell 4, a plurality of ventilation grooves 19 are formed in the side wall of the upper shell 4, so that the excess air can be exhausted to the outside of the lower shell 5 through the plurality of ventilation grooves 19.

[0091] In addition, since the air blown out of the upper shell 4 will be cooled after absorbing heat from the refrigerant, a wind collecting cover 27 is fixedly installed on the lower shell 5 outside the ventilation groove 19 and the heat dissipation groove 21, so that the low-temperature air blown out of the ventilation groove 19 and the heat dissipation groove 21 will first enter the wind collecting cover 27, then pass through one end of the plastic hose in communication with the wind collecting cover 27 and the other end of the plastic hose passing out from between the bottom of the disaster relief tent and the ground, and be placed outside the disaster relief tent, so that the low-temperature air in the wind collecting cover 27 is discharged out of the tent through the plastic hose, avoiding the influence of the low-temperature air on the temperature rise in the tent.

[0092] As an embodiment of the present application, a ventilation port 22 is formed in the side wall of the lower shell 5, and a filter screen 23 is fixedly installed in the ventilation port 22, and a curved pipe 18 is fixedly installed on the back of the filter screen 23;

[0093] The lower shell 5 is provided with a rectangular ventilation port 22 in the side wall, and the filter screen 23 is fixedly installed in the ventilation port 22, and the curved pipe 18 is fixedly installed on the back of the filter screen 23, and the ventilation port 22 is located on the front of the lower shell 5, so that the air flow blown by the main impeller 6 can be blown out of the lower shell 5 through the ventilation port 22, and in addition, the filter screen 23 is fixedly installed in the ventilation port 22, which can avoid that the personnel touch the inside of the lower shell 5 by mistake during actual use at home, and can avoid that the personnel are injured by the main impeller 6 or are scalded by the curved pipe 18, thereby improving the safety, and on the other hand, the filter screen 23 can avoid that the impurities in the air are accumulated in the lower shell 5 when the device is at rest, and can blow the impurities to the surface of the human body after starting, thereby improving the use experience;

[0094] In addition, the filter screen 23 fixes the curved pipe 18 in front of the main impeller 6, so that the air in the lower shell 5 can be heated when blown out of the filter screen 23 through the curved pipe 18 under the drive of the main impeller 6.

[0095] As an embodiment of the present application, a steam hole 24 is formed in the upper end of the water tank 15 on the second sealing plate 12;

[0096] During the heating process, steam will inevitably be generated in the water tank 15, and the inside of the water tank 15 is a closed space, so that the accumulation of steam will increase the air pressure in the water tank 15, and over a long period of time, safety hazards may occur;

[0097] In order to avoid the above safety hazards, the present application has the following advantages:

[0098] I. The hot water is guided out of the curved pipe 18, which increases the contact area between the hot water in the water tank 15 and the air in the lower shell 5, and makes the hot water and steam complete heat release in the curved pipe 18, so that the steam can be re-condensed into water in the curved pipe 18, thereby reducing the accumulation of water vapor in the water tank 15;

[0099] Two, a steam hole 24 is formed on the upper end of the water tank 15 at the second sealing plate 12, and an electromagnetic valve is fixedly installed in the steam hole 24. The position of the steam hole 24 is above the liquid level of the water tank 15, so that the electromagnetic valve can be opened according to the electric control instruction during the heating process of the water in the water tank 15. The electric control instruction can be issued by a mobile phone or other electronic control unit, so that the steam hole 24 is penetrated, and the steam in the water tank 15 can enter the rotation range of the main impeller 6 from the water tank 15 through the steam hole 24. The escaped steam can directly heat the air, reduce the air pressure in the water tank 15, and be blown to the human body surface and the surrounding environment in the dry winter, thereby playing a humidifying role and avoiding the discomfort caused by the excessive loss of body water after long-term heating in the tent.

[0100] As an embodiment of the present application, a water supplement hole 25 is formed on the lower end of the water tank 15 at the side wall of the lower shell 5.

[0101] As can be seen from the above, the water in the water tank 15 will sometimes be discharged in the form of steam to the outside of the water tank 15 under the control of the electromagnetic valve, which will cause the consumption of the water in the water tank 15. Therefore, the water supplement hole 25 is formed on the lower end of the water tank 15 at the side wall of the lower shell 5. One end of the water supplement hole 25 is communicated with the water tank 15. When water needs to be added, the butterfly valve at the water supplement hole 25 is opened, and pure water is injected into the funnel through the pipeline connected to the other end of the water supplement hole 25. The pure water enters the water tank 15 through the water supplement hole 25. Under the monitoring of the electronic liquid level sensor in the water tank 15, when the water level reaches two-thirds of the height of the water tank 15, the electronic liquid level sensor feeds back a signal to a receiving device. The receiving device can be a mobile phone or an electronic display screen, or other alarm or data display instrument. At this time, the butterfly valve is manually closed to stop water injection.

[0102] In addition, adding pure water to the water tank 15 can reduce the generation of scale in the water tank 15 during the heating process, reduce the difficulty of later maintenance, and prolong the service life of the device.

[0103] As an embodiment of the present application, the air inlet channel 9 is made of a copper sheet.

[0104] Copper is a metal material with good thermal conductivity. The air inlet channel 9 is made of a copper sheet, so that the air entering the air inlet channel 9 can quickly complete heat transfer through contact with the copper sheet, quickly warm up, and improve the heating efficiency of the air.

[0105] As an embodiment of the present application, the inner wall of the water tank 15 is paved with thermal insulation material except the outer wall of the air inlet channel 9.

[0106] The inner wall of the water tank 15 is paved with thermal insulation material except the outer wall of the air inlet channel 9, which can effectively ensure that the heat supplied by the heat pump to the water body is absorbed by the air inside the lower shell 5 as much as possible, improve the energy utilization efficiency, and will not cause more energy loss.

[0107] Here, the thermal insulation material can be ceramic thermal insulation material, and of course can also be other thermal insulation materials that do not produce harmful substances to the human body after heating.

[0108] Working principle:

[0109] Before the device starts, water is first injected into the water tank 15, and the maximum height of the water body should be two-thirds of the height of the water tank 15;

[0110] When the device starts, the double-shaft motor 7 and the compressor 2 are powered on, and the upper end output shaft of the double-shaft motor 7 will drive the fan 8 fixedly connected with the upper end output shaft of the double-shaft motor 7 to rotate in the upper shell 4. The rotating fan 8 will generate negative pressure to suck the air outside the top of the upper shell 4 into the upper shell 4 through the multiple second filter holes 26 opened on the top surface of the upper shell 4. The air entering the inside of the upper shell 4 will first contact the outer surface of the evaporator 1 fixedly connected with the top end and the side wall of the upper shell 4, and the spiral evaporator 1 can maximize the contact area between the outer surface of the evaporator 1 and the air.

[0111] The evaporator 1 is filled with low-boiling liquid refrigerant. When the low heat in the air contacts the surface of the evaporator 1 and heat transfer occurs, the liquid refrigerant will be vaporized due to the heat absorbed from the air, i.e. from liquid to gas. The gaseous refrigerant will enter the compressor 2 fixedly installed on the upper surface of the third sealing plate 13 through the pipeline and under the suction stroke of the compressor 2. The gaseous refrigerant compressed by the compressor 2 will change from low temperature and low pressure to high temperature and high pressure, and continue to pass through the pipeline to reach the condenser 3 fixedly installed on the lower surface of the third sealing plate 13. The condenser 3 is also spiral and located in the water tank 15. At this time, the high-temperature and high-pressure gaseous refrigerant will release heat through the outer wall of the condenser 3 to the water body in close contact with the outer wall of the condenser 3 in the water tank 15, thereby achieving heating of the water body. The high-temperature and high-pressure gaseous refrigerant releases heat in the condenser 3 and is condensed into a gas-liquid mixture, and finally becomes liquid refrigerant after being throttled and decompressed by the expansion valve. Then it returns to the evaporator 1 at the top of the upper shell 4 through the pipeline, and the above process is repeated, circulating back and forth. With the continuous rotation of the fan 8, the above process is continuously repeated, thereby completing the continuous heating process of the water body in the water tank 15.

[0112] Meanwhile, the lower end output shaft of the double-shaft motor 7 drives the main impeller 6 fixedly connected with the lower end output shaft of the double-shaft motor 7 to rotate in the lower shell 5. The rotating main impeller 6 synchronously drives the water wheel 16 fixedly connected with the bottom end of the main impeller 6 to rotate. The water wheel 16 is located at the bottom of the water tank 15. Therefore, in the process of rotation of the water wheel 16, on the one hand, the water body in the water tank 15 can be stirred from the bottom of the water tank 15, so that the heat released by the condenser 3 in the water tank 15 can be uniformly absorbed by the water body. On the other hand, the water flow at the bottom can be pushed to the water inlet 17 fixedly installed on the lower surface of the fourth sealing plate 14 along the rotation direction of the water wheel 16. The water inlet 17 is a cuboid and is provided with a hole inside, so as to facilitate the water flow to enter. Since one end of the water inlet 17 is communicated with the curved pipe 18 through a pipeline, the water flow at the bottom of the water tank 15 will enter the curved pipe 18 through the water inlet 17 and the pipeline under the action of the water wheel 16, and will continue to flow along the curved pipe 18 under the continuous pushing of the water wheel 16, until the water flow reenters the upper end of the water tank 15 from the other end of the curved pipe 18 through the pipeline on the upper end of the lower shell 5.

[0113] With the continuous heating of the water body in the water tank 15, the water body in the water tank 15 can reach a temperature of 75-85 degrees Celsius. The steam generated by the hot water can heat the outer wall of the air inlet channel 9 at the top end of the water tank 15 (except the top end outer wall), so that the air can be preliminarily heated by the air inlet channel 9 when passing through the air inlet channel 9.

[0114] As can be seen from the above process, when the water body in the water tank 15 is heated, the hot water will be transported to the curved pipe 18 under the rotation of the water wheel 16. The curved pipe 18 is in the shape of “Z”. The hot water in the curved pipe 18 can also release heat to the air in the lower shell 5 through the pipe wall of the curved pipe 18, so as to further heat the air.

[0115] Therefore, under the action of the main impeller 6, the air outside the rear side of the lower shell 5 will be preliminarily heated in the air inlet channel 9 and then heated again in the curved pipe 18 fixedly installed in front of the main impeller 6 when passing through the air inlet channel 9 from the rear of the main impeller 6 to the main impeller 6, thereby improving the heating efficiency of the water heating system.

[0116] The heated hot air will pass through the curved pipe 18 and the front end side wall of the lower shell 5 under the continuous rotation of the main impeller 6, and will be blown out of the lower shell 5, so as to finally realize the heating of the surface of the human skin and the surrounding environment.
