Technical Field
[0001] This utility model relates to the field of hot water technology, specifically a hot water system that combines solar thermal and air source heat pump technology. Background Technology
[0002] A vacuum tube solar water heater is a device that uses solar energy to heat water. It mainly consists of collector tubes, a water tank, a support frame, and connecting pipes. The inside of the collector tubes is a vacuum, which effectively reduces heat loss and improves collection efficiency. When sunlight shines on the collector tubes, the heat-absorbing material inside absorbs solar radiation energy and converts it into heat energy, which is then transferred to the water through heat conduction, thus producing hot water. An air source heat pump water heater (also known as a heat pump water heater) is a device that uses heat energy from the air to heat water. It uses a compressor to compress a low-temperature, low-pressure refrigerant into a high-temperature, high-pressure gas, which then transfers heat to the water through a condenser, raising the water temperature. Simultaneously, the refrigerant absorbs heat from the air in the evaporator, thus achieving heat recycling. A complementary solar thermal and air source heat pump hot water system combines the advantages of solar thermal and air source heat pumps. This system achieves an efficient and stable hot water supply through the coordinated operation of solar collectors and air source heat pumps. When solar energy is abundant, the system can rely on solar energy for hot water supply. When solar energy is insufficient, the air source heat pump starts, utilizing heat from the air to supplement heating. This system achieves high energy efficiency and reduces users' hot water usage costs.
[0003] When using a complementary solar thermal and air source heat pump hot water system, under sunny or sunny conditions, the solar collector absorbs solar radiation to heat the water. Since solar collectors are generally installed outdoors, dust and other contaminants tend to adhere to and accumulate on the surface of the vacuum tubes after long-term exposure to the air. Existing technologies cannot effectively clean the vacuum tubes, and the accumulation of dust can affect the projection of sunlight, hindering the vacuum tubes from absorbing solar radiation effectively. Consequently, the heating effect and efficiency of cold water cannot be guaranteed. Therefore, to solve the above problems, a complementary solar thermal and air source heat pump hot water system is proposed. Summary of the Invention
[0004] The purpose of this invention is to provide a hot water system that combines solar thermal and air-source heat pump technology to solve the problem mentioned in the background art, which is that the vacuum tubes cannot be cleaned properly, and the accumulation of dust and other substances can affect the projection of sunlight, making it difficult for the vacuum tubes to absorb solar radiation energy effectively, thus failing to ensure the heating effect and efficiency of cold water.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-6 One embodiment provided by this utility model:
[0024] The motor 22 used in this application is a product that can be purchased directly from the market. Its principle and connection method are existing technologies well known to those skilled in the art, so they will not be described in detail here.
[0025] A complementary solar thermal and air source heat pump hot water system includes a housing, which includes a support frame 1. An insulated water tank 11 is fixedly connected to the top of the support frame 1. A vacuum tube 12 is installed inside the support frame 1. An inlet pipe 13 is fixedly connected to the surface of the insulated water tank 11. An outlet pipe 14 is fixedly connected to the end of the insulated water tank 11 away from the inlet pipe 13. A hot water tank 15 is fixedly connected to the end of the outlet pipe 14 away from the insulated water tank 11. An air source heat pump unit 16 is installed on one side of the hot water tank 15. A fan grille 17 is installed on the surface of the air source heat pump unit 16. A connecting pipe 18 is fixedly connected to the surface of the air source heat pump unit 16. The end of the connecting pipe 18 away from the air source heat pump unit 16 is connected to the hot water tank. The hot water tank 15 is fixedly connected to the surface of the hot water tank 15, and a hot water outlet 19 is fixedly connected to it. Cold water can enter through the inlet pipe 13. The vacuum tube 12 can collect solar energy and convert it into heat energy to heat the cold water, which then enters the insulated water tank 11. The cold water can then enter the hot water tank 15 for storage through the outlet pipe 14. The air source heat pump host 16 absorbs the low-temperature heat from the air, vaporizes it through the fluorine medium, compresses it through the compressor, increases its pressure and temperature, and then converts it into heat for water through the heat exchanger, thus heating the water in the hot water tank 15. Therefore, through the cooperation of the insulated water tank 11 and the air source heat pump host 16, energy efficiency can be achieved.
[0026] The surface of the bracket 1 is provided with a cleaning mechanism, which includes a first fixed block 2, which is fixedly connected to the surface of the bracket 1. A reciprocating screw 21 is movably connected to the inner side of the first fixed block 2. A motor 22 is fixedly installed on the surface of the first fixed block 2. A first moving block 23 is movably connected to the surface of the reciprocating screw 21. A brush plate 24 is fixedly connected to the surface of the first moving block 23. The operation of the motor 22 can drive the reciprocating screw 21 to rotate. The first moving block 23 will drive the brush plate 24 to move back and forth under the action of the reciprocating screw 21. This allows the brush plate 24 to clean the vacuum tube 12, making it easier for the vacuum tube 12 to absorb solar radiation energy better, thereby ensuring the heating effect and quality.
[0027] Furthermore, the cleaning mechanism also includes a second fixing block 25, which is fixedly connected to the end of the bracket 1 away from the first fixing block 2. A limit rod 26 is fixedly connected to the inner surface of the second fixing block 25, and a second moving block 27 is fixedly connected to the surface of the brush plate 24. By setting the limit rod 26 and the second moving block 27, the brush plate 24 can be limited, which can prevent the brush plate 24 from shifting under the action of the reciprocating screw 21 by the first moving block 23, so as to facilitate the stable movement of the brush plate 24.
[0028] Furthermore, the output end of the reciprocating screw 21 and the motor 22 are fixedly connected, one end of the brush plate 24 is fixedly connected to the first moving block 23, the other end of the brush plate 24 is fixedly connected to the second moving block 27, and the second moving block 27 is movably connected to the limit rod 26. Through the setting of the brush plate 24, it can rub against the surface of the vacuum tube 12 during the movement, which can clean the vacuum tube 12 and prevent the accumulation of dust and other substances.
[0029] Furthermore, a disassembly and assembly mechanism is provided on the inner side of the fan cover 17. The disassembly and assembly mechanism includes an installation block 3, which is fixedly connected to the surface of the fan cover 17. An installation groove 31 is opened on the inner side of the air source heat pump host 16, and a movable groove 32 is opened on the inner side of the fan cover 17. A movable rod 33 is movably connected to the inner side of the movable groove 32. A connecting block 34 is fixedly connected to the surface of the movable rod 33, and an insertion rod 35 is fixedly connected to the surface of the connecting block 34. A slot 36 is opened on the inner wall of the installation groove 31, and a spring 37 is fixedly connected to the surface of the movable rod 33. By moving the movable rod 33 within the fan cover 17 and the installation block 3, the insertion and separation of the insertion rod 35 and the slot 36 can be realized, thereby facilitating the disassembly and assembly of the fan cover 17 and thus facilitating the maintenance of the fan.
[0030] Furthermore, the mounting blocks 3 are fixedly connected to the fan grille 17 in four groups, and the mounting grooves 31 are opened in four groups on the inner side of the air source heat pump host 16. The movable grooves 32 are opened on the inner side of the fan grille 17 and the mounting blocks 3. Through the cooperation of the mounting blocks 3 and the mounting grooves 31, the fan grille 17 can be positioned during installation, which can ensure the accuracy of the installation.
[0031] Furthermore, the movable rod 33, connecting block 34, and insert rod 35 are all movable inside the movable slot 32. One end of the spring 37 is fixedly connected to the fan grille 17, and the other end of the spring 37 is fixedly connected to the movable rod 33. By setting the spring 37, the movable rod 33 can be reset, thereby enabling the movable rod 33 to drive the connecting block 34 and insert rod 35 to move, facilitating the insertion of the insert rod 35 into the slot 36, thus facilitating the connection and fixation of the fan grille 17 and the air source heat pump host 16.
[0032] Working principle: When in use, the motor 22 is electrically connected to an external power source. The operator starts the motor 22 by pressing the switch. The motor 22 drives the reciprocating screw 21 to rotate. The brush plate 24 is restricted by the limit rod 26 and the second moving block 27, so that the first moving block 23 will move back and forth under the action of the reciprocating screw 21, thereby realizing the reciprocating motion of the brush plate 24, which can realize the cleaning of the vacuum tube 12 by the brush plate 24.
[0033] Pulling the movable rod 33 allows it to move within the movable slot 32, causing the connecting block 34 to move accordingly and separating the insertion rod 35 from the slot 36. At this point, the spring 37 is stretched, releasing the fixing of the mounting block 3 and the air source heat pump unit 16. Then, pulling the fan grille 17 separates the mounting block 3 from the mounting slot 31, allowing the fan grille 17 to be removed for cleaning or fan maintenance. When fixing the fan grille 17, the mounting block 3 is inserted into the mounting slot 31, and the movable rod 33 is released. The movable rod 33 returns to its original position under the rebound of the spring 37, causing the connecting block 34 to move the insertion rod 35 and engage with the slot 36, thus fixing the mounting block 3 and the air source heat pump unit 16 and allowing the fan grille 17 to be installed.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
