[0029] A water inlet pipe 7 is provided above the inner shell 13, and a water outlet pipe 17 is provided below the inner shell 13. One end of the water inlet pipe 7 is connected to the heat collecting pipe 4 with the smallest diameter, and the other end of the water inlet pipe 7 is connected to the water guide pipe 9. One end of the water outlet pipe 17 is connected to the water guide pipe 9, and the other end of the water outlet pipe 17 is connected to the heat collecting pipe 4 with the largest diameter. An electromagnetic water valve 8 is provided on the water inlet pipe 7, and a water pump 10 is provided on the water outlet pipe 17.

[0030] A water inlet thermometer 12 is provided at the connection between the water inlet pipe 7 and the water guide pipe 9, and a water outlet thermometer 18 is provided at the connection between the water outlet pipe 17 and the water guide pipe 9;

[0031] A heating strip 15 is provided in the water conduit 9 .

[0032] Preferably, a control module is provided in the air energy heat pump host 1, and the control module includes a PLC, and the electromagnetic water valve 8, the water inlet thermometer 12, the water outlet thermometer 18, the water pump 10 and the heating strip 15 are all electrically connected to the PLC.

[0033] Preferably, the heat insulation layer 11 is filled with polyurethane foam, the support plate 3 is hollow, and the support plate 3 is filled with polyurethane foam.

[0034] Preferably, the water pipe 9 is a copper pipe, and the heat conducting block 14 is an aluminum block;

[0035] Preferably, the shell wall of the inner shell 13 is hollow, and the shell wall of the inner shell 13 is evacuated;

[0036] Preferably, a plurality of reinforcing ribs 16 are provided in the inner shell 13 .

[0037] Preferably, there are two heating bars 15 , and the two heating bars 15 are respectively located on both sides of the inner shell 13 .

[0038] The air energy heat pump main unit 1 heats the cold water, and the heated hot water is sent to the inner shell 13 for storage.

[0039] During the day, the heat collecting tube 4 absorbs solar energy and heats the water in the heat collecting tube 4. A number of annular heat collecting tubes 4 are arranged here, and the interval interconnection is achieved through the conduit 5, that is, the distance between the water inlet and the water outlet of two adjacent heat collecting tubes 4 is maximized, so that the water flow in each heat collecting tube 4 is longest, thereby increasing the heat absorption of the water in the heat collecting tube 4, that is, increasing the temperature of the flowing water in the heat collecting tube 4, and then entering the water pipe 9 from the water inlet pipe 7, squeezing the water in the water pipe 9 through the water outlet pipe 17, and then lifting it to the heat collecting tube 4 through the water pump 10, so as to realize the circulation heating of the water, and the water inlet thermometer 12 and the water outlet thermometer 18 are used to detect the water temperature at the water inlet end and the water outlet end of the water pipe 9 respectively. When the heat collecting tube 4 absorbs solar energy for heating during the day , the water temperature detected by the water inlet thermometer 12 is higher than the water temperature detected by the water outlet thermometer 18, then the electromagnetic valve 8 is in the open state to achieve normal circulation; when there is no sun or the sunlight is weak, the water temperature detected by the water inlet thermometer 12 will be lower than the water temperature detected by the water storage thermometer 18. Such water circulation actually causes heat loss, then the PLC controls the electromagnetic water valve 8 to close, the water pump 10 stops working, and the water in the water pipe 9 no longer circulates, and then the heating strip 15 is energized for heating, so that it electrically heats the water in the conduit 9, and at this time the water inlet thermometer 12 and the water outlet thermometer 18 are used to monitor the temperature in the water pipe 9 in real time. When the temperature is higher than the preset value, the PLC controls the heating strip 15 to stop working, so that a certain water temperature is maintained in the water pipe 9.

[0040] When the second day arrives, the opening time of the electromagnetic water valve 8 can be preset, such as opening it at 9 am, and then the water temperature can be detected by the water inlet thermometer 12 and the water outlet thermometer 18. When the temperature detected by the water inlet thermometer 12 is higher than that of the water outlet thermometer 18, it means that the heat collection and heating can be circulated normally.

[0041] If during the day, within the preset time range, such as from 9 am to 4 pm, the temperature detected by the water inlet thermometer 12 is lower than the water temperature detected by the water outlet thermometer 18, it means that the solar energy collection is not as expected and the sunlight intensity is insufficient. In this case, the PLC controls the electromagnetic water valve 8 to close for 30 minutes, and then repeats the above operation. After 4 pm, the PLC controls the electromagnetic water valve 8 to close directly without circulation.

[0042] Here, the purpose of keeping the water in the inner shell 13 warm is achieved by firstly setting a vacuum inside the inner wall of the inner shell 13 to achieve insulation, thereby reducing the heat loss rate, and then forming an outer temperature envelope by embedding the heat conductive block 14 in the inner shell 13, that is, when the temperature difference between the outer temperature and the water temperature in the inner shell 13 is smaller, the heat loss rate of the water in the inner shell 13 will be reduced, thereby achieving the second insulation, and the water in the water pipe 9 is heated by the uninterrupted circulation of the heat collecting pipe 4, thereby ensuring the water temperature in the heat collecting pipe 4, and further reducing the temperature difference between the water temperature in the heat collecting pipe 4 and the water temperature in the inner shell 13, which can reduce the heat loss caused by heat exchange and form the third insulation, and the outermost insulation layer 11 serves as the fourth insulation, which is mainly used to isolate the heat exchange between the heat conducting pipe 9 and the outside world and reduce heat loss.

[0043] Four layers of thermal insulation protection are used here to achieve the insulation effect of the water in the inner shell 13. The water pipe 9 alternately heats the water in the heat pipe 9 through the heat collecting pipe 4 and the heating strip 15, so as to always maintain the water temperature in the heat pipe 9, thereby forming a temperature barrier, thereby reducing the heat exchange efficiency, and then reducing the heat loss in the inner shell 13. The reduction in the heat loss rate of the water in the inner shell 13 improves the use efficiency of hot water. The use of solar energy for heating and insulation also reduces the working intensity of the air energy heat pump host 1, saves energy and extends the service life of the equipment. Through data monitoring, intelligent control is achieved, and the degree of automation of the equipment is improved.

[0044] Compared with the prior art, this high-efficiency and energy-saving intelligent industrial water heater collects solar heat by setting a heat collecting tube 4, which is used to heat the water temperature of the water guide 9, and forms a temperature barrier on the periphery of the inner shell 13, thereby slowing down the heat loss rate in the inner shell 13, thereby achieving energy-saving effects, and through real-time monitoring of water temperature, it can realize intelligent switching between heat collection and electric heating, thereby improving the efficiency of maintaining water temperature.

[0045] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
