[0002] With increasing emphasis on environmental protection and energy conservation, air source heat pump water heaters, as a highly efficient and energy-saving water heating device, are being used more and more widely. However, some problems still exist in the use of existing air source heat pump water heaters;

[0003] For vertical air source heat pump water heaters, due to their small contact area with the ground at the bottom, they are prone to shaking or even tipping over and being damaged if subjected to external forces such as collisions or vibrations. This not only affects the normal use of the air source heat pump water heater but may also pose a safety hazard to surrounding people and property.

[0004] Furthermore, during the installation of air source heat pump water heaters, a significant height difference between the water pipes and the hot and cold water inlets on the heater is often encountered, making pipe connections difficult. Forcing a connection may result in insecure connections, leaks, and other problems, affecting the performance and safety of the air source heat pump water heater.

[0005] To address these issues, a new type of air source water heater and its supporting devices are needed, which can improve the stability of vertical air source water heaters while facilitating installation and water pipe connection to meet people's needs for using air source water heaters.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and environmentally friendly air source water heater, comprising a vertical insulated water tank and a heat pump unit installed at the top of the vertical insulated water tank. The vertical insulated water tank is composed of a metal outer shell, an insulated inner liner, and a metal inner liner, wherein the metal outer shell and the metal inner liner are the outer and inner layers of the vertical insulated water tank, respectively, and the insulated inner liner is located between the metal outer shell and the metal inner liner. A lifting and placing device is provided on the outside of the bottom of the vertical insulated water tank.

[0008] Preferably, the lifting and placing device includes a placing base, a water tank placement seat, an anti-detachment placement groove, lifting adjustment holes, and lifting support screws. The water tank placement seat has an anti-detachment placement groove inside, with the opening of the anti-detachment placement groove facing upwards. The bottom end of the vertical insulated water tank is inserted into the anti-detachment placement groove. The placing base is provided on the lower side of the water tank placement seat. Multiple lifting adjustment holes are equidistantly arranged inside the water tank placement seat, and multiple lifting adjustment holes are all close to the edge of the water tank placement seat. Lifting support screws are threaded into each of the multiple lifting adjustment holes, and the bottom ends of the multiple lifting support screws are fixedly connected to the placing base by welding.

[0009] Preferably, the lifting and placing device further includes an internally threaded anti-detachment cap, an internally threaded lifting support sleeve, and an anti-slip pad. The top ends of the plurality of lifting support screws are all threaded with internally threaded anti-detachment caps, and the external ends of the plurality of lifting support screws are all threaded with internally threaded lifting support sleeves. The plurality of internally threaded lifting support sleeves are all located at the bottom of the water tank placement seat, and an anti-slip pad is attached and fixed to the outer wall of the bottom end of the placement chassis.

[0010] Preferably, the lifting support screw can move up and down in the lifting adjustment hole, and the internal thread lifting support sleeve can move up and down outside the lifting support screw by rotating clockwise and counterclockwise through the thread action.

[0011] Preferably, when the internal thread lifting support sleeve moves upward, it will lift the water tank placement seat upward.

[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] This utility model provides, for example Figure 1-4 The illustrated high-efficiency and environmentally friendly air source water heater includes a vertical insulated water tank 9 and a heat pump unit 7 installed at the top of the vertical insulated water tank 9. The vertical insulated water tank 9 is composed of a metal outer shell, an insulated inner tank, and a metal inner liner. The metal outer shell and the metal inner liner are the outer and inner layers of the vertical insulated water tank 9, respectively, with the insulated inner liner located between the metal outer shell and the metal inner liner. This high-efficiency and environmentally friendly air source water heater utilizes the heat pump principle, absorbing heat from the surrounding environment through the heat pump unit 7 and transferring the heat to the water in the vertical insulated water tank 9. The vertical insulated water tank 9, composed of a metal outer shell, an insulated inner tank, and a metal inner liner, provides good insulation, reducing heat loss. A hot water outlet 3 is located on the upper right side of the center of the vertical insulated water tank 9, and a cold water inlet 2 is located on the lower right side of the center of the vertical insulated water tank 9. A drain valve 1 is located below the cold water inlet 2. A controller 8 is located inside the front end of the heat pump host 7. A temperature probe is located inside the metal inner tank of the vertical insulated water tank 9. The temperature probe is electrically connected to the controller 8. Multiple heat dissipation holes 4 are equidistantly arranged inside both ends of the heat pump host 7. The temperature probe monitors the water temperature in real time and works with the controller 8 to achieve precise temperature control. When the water temperature is lower than the set temperature, the controller 8 starts the heat pump host 7, which absorbs heat from the surrounding environment and transfers it to the water in the tank until the water temperature reaches the set temperature.

[0024] like Figure 1 and Figure 2As shown, an air inlet 5 is located on the right side of the top center of the heat pump unit 7, and an air outlet 6 is located on the left side of the top center of the heat pump unit 7. Both the air inlet 5 and the air outlet 6 have metal protective meshes installed inside their top openings. The air inlet 5 and the air outlet 6 allow air circulation, providing the necessary airflow for the heat exchange of the heat pump unit 7. The metal protective meshes prevent foreign objects from entering the heat pump unit 7, protecting the equipment. In addition to the compressor and heat exchanger, the heat pump unit 7 also contains components such as an expansion valve and a fan. The heat pump unit 7 operates using the reverse Carnot cycle principle. First, the compressor starts, compressing the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant enters the heat exchanger, where it reacts with the water in the vertical insulated water tank 9. Heat exchange occurs, transferring heat to the water in the tank and raising its temperature. Simultaneously, the refrigerant's temperature decreases, transforming it into a high-temperature, high-pressure liquid refrigerant. This high-temperature, high-pressure liquid refrigerant then passes through an expansion valve for throttling and pressure reduction, becoming a low-temperature, low-pressure liquid refrigerant. This low-temperature, low-pressure liquid refrigerant enters another heat exchanger, where it absorbs heat from the surrounding environment in the evaporator, raising its temperature and transforming into a low-temperature, low-pressure gaseous refrigerant. The fan promotes airflow within the heat pump unit 7, improving heat exchange efficiency. The low-temperature, low-pressure gaseous refrigerant is then drawn back into the compressor, starting the next cycle. Through continuous circulation, the heat pump unit 7 continuously absorbs heat from the surrounding environment and transfers it to the water in the vertical insulated water tank 9, thereby achieving the purpose of heating the water.

[0025] like Figure 1 , Figure 3 and Figure 4As shown, a lifting and placing device 10 is provided on the outside of the bottom of the vertical insulated water tank 9. The lifting and placing device 10 includes a placing base 11, a water tank placement seat 12, an anti-detachment placement groove 13, lifting adjustment holes 14, and lifting support screws 16. The anti-detachment placement groove 13 is provided inside the water tank placement seat 12, with the opening of the anti-detachment placement groove 13 facing upward. The bottom of the vertical insulated water tank 9 is inserted into the anti-detachment placement groove 13. The placing base 11 is provided on the lower side of the water tank placement seat 12. Multiple lifting adjustment holes 14 are equidistantly arranged inside the water tank placement seat 12. Multiple lifting adjustment holes 14 are all close to the edge of the water tank placement seat 12. Lifting support screws 16 are threaded into each of the multiple lifting adjustment holes 14. The bottom end of the 16 is fixedly connected to the mounting base 11 by welding. The lifting mounting device 10 also includes an internally threaded anti-detachment cap 15, an internally threaded lifting support sleeve 17, and an anti-slip pad 18. The top ends of multiple lifting support screws 16 are threaded with internally threaded anti-detachment caps 15, and the external parts of multiple lifting support screws 16 are threaded with internally threaded lifting support sleeves 17. The multiple internally threaded lifting support sleeves 17 are all located at the bottom of the water tank placement seat 12. The bottom outer wall of the mounting base 11 is glued and fixed with an anti-slip pad 18. The lifting support screws 16 can move up and down in the lifting adjustment hole 14. The internally threaded lifting support sleeves 17 can move up and down outside the lifting support screws 16 by rotating clockwise and counterclockwise through the thread action.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, when the internally threaded lifting support sleeve 17 moves upward, it will lift the water tank placement seat 12 upward. The circular outer wall of the internally threaded lifting support sleeve 17 is densely covered with anti-slip grooves to increase contact friction. The internally threaded anti-detachment cap 15 can be directly removed from the outside of the top of the lifting support screw 16 by rotating counterclockwise. When the vertical insulated water tank 9 is placed on the ground by the lifting and placing device 10, first, place the placement base 11 on a stable ground to ensure that the anti-slip pad 18 is in full contact with the ground to increase stability. Place the water tank placement seat 12 on the placement base 11, so that the lifting support screw 16 is aligned with the lifting adjustment hole 14 on the water tank placement seat 12 and passes through it. Then, thread the internally threaded anti-detachment cap 15 onto the top of each lifting support screw 16 and rotate to adjust the internal thread on each lifting support screw 16. The internally threaded lifting support sleeve 17 is used to ensure that multiple internally threaded lifting support sleeves 17 are on the same horizontal plane and supported at the bottom of the water tank placement seat 12. Then, the bottom of the vertical insulated water tank 9 is inserted into the anti-detachment placement groove 13 inside the water tank placement seat 12 to ensure that the water tank is placed stably. When it is necessary to adjust the height of the air source water heater, the internally threaded lifting support sleeve 17 is rotated clockwise or counterclockwise to move up and down on the lifting support screw 16. When the internally threaded lifting support sleeve 17 moves upward, it will raise the water tank placement seat 12 and the vertical water tank. When the internally threaded lifting support sleeve 17 moves downward, the vertical insulated water tank 9 and the water tank placement seat 12 will automatically descend by their own weight, so that the water tank placement seat 12 is always in close contact with the top of the internally threaded lifting support sleeve 17, thereby achieving the purpose of flexibly adjusting the height of the air source water heater.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
