Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] An easy-to-install air source water heater, such as Figure 1 , 2 As shown, the system includes a base 9, on which a water storage tank 1 is fixedly installed. Several support rods are fixedly connected to one end of their bottom, and the other ends of the support rods are fixedly connected to the base 9. A heat exchange coil 2 is installed inside the water storage tank 1, and the heat exchange coil 2 is fixedly installed on the water storage tank 1. The outer peripheries of both ends of the heat exchange coil 2 are respectively fixedly connected to the inner walls of pre-drilled holes on the water storage tank 1. A water inlet pipe 4 is connected to the water storage tank 1. The top of the water storage tank 1 is open and has a flange 5. An expansion water tank 6 is located on one side of the water storage tank 1. The expansion water tank 6 has openings at both ends and flanges 5 respectively. Adjacent flanges 5 are connected together by connectors. A sealing cover 7 is located on the top of the expansion water tank 6, and the sealing cover 7 and adjacent flanges 5 are also connected together by connectors. A water outlet pipe 8 is connected to the sealing cover 7. This utility model has a simple structure and ingenious design. It designs the water tank of the water heater as a basic and relatively small storage tank 1 and an expandable extension tank 6. The tanks can be transported and reassembled separately, which solves the problem of existing integrated water tanks being large, heavy and inconvenient to transport and install. The number of extension tanks 6 can also be selected according to needs, realizing on-demand capacity expansion, which can meet actual needs and is suitable for promotion. When using this device, first move the water storage tank 1 and base 9 to the installation position. Then, select an appropriate number of expansion water tanks 6 according to the capacity requirements and move them to the installation position. Then, connect the flange 5 at one end of the first expansion water tank 6 to the flange 5 on the water storage tank 1 using a connector. If there are multiple expansion water tanks 6, connect the flanges 5 on adjacent expansion water tanks 6 one by one using a connector. After the expansion water tanks 6 are installed, connect the sealing cover 7 to the flange 5 of the uppermost expansion water tank 6 using a connector. The water tank assembly is then complete. The single expansion water tank 6 and water storage tank 1 are small in size, making them easier to move and install. After assembly, connect the heat exchange coil 2 to the compressor of the outdoor unit of the air source water heater, connect the inlet pipe 4 to the water source, and connect the outlet pipe 8 to the water pipe.

[0017] Specifically, as shown in the figure, the connector in this embodiment includes two arc-shaped clamps 20. The radial cross-section of the clamps 20 is C-shaped. One end of the two clamps 20 is hinged together, and the other end of the two clamps 20 is connected together by bolts and nuts. The other end of the clamps 20 is respectively fixed with connecting plates having connecting holes, and the bolts pass through the connecting holes and are threadedly connected to the nuts. When connecting the two flanges 5, the two clamps 20 are rotated along the hinge axis to open them, and then fitted onto the two flanges 5 so that the clamps 20 cover the flanges 5. Then, they are fixed with bolts and nuts, and the extended water tank 6 is connected to the water storage tank 1. The installation is convenient and efficient, and the force is more evenly distributed when the two flanges 5 are connected by the clamps 20, making it more convenient to use.

[0018] Specifically, as shown in the figure, in this embodiment, sealing rings 30 are provided between the sealing cover 7 and the corresponding flange 5, and between the two flanges 5 that are in contact with each other. The sealing rings 30 reduce the possibility of water leakage by increasing the sealing between the water storage tank 1 and the extended water tank 6, and between the extended water tanks 6 and the extended water tanks 6.

[0019] Furthermore, as shown in the figure, in this embodiment, a first insulation shell 40 is fixedly installed on the water storage tank 1, a tubular second insulation shell 41 is provided on the outside of the extended water tank 6, an insulation cover 42 is provided on one side of the sealing cover 7, the water outlet pipe 8 passes through the insulation cover 42, both ends of the heat exchange coil 2 and one end of the water inlet pipe 4 extend to the outside of the first insulation shell 40 respectively, several insert rods 43 are fixedly installed on the bottom of the insulation cover 42 and the second insulation shell 41 respectively, and several slots 44 are opened on the top of the second insulation shell 41 and the first insulation shell 40 respectively, and the insert rods 43 are inserted into the corresponding slots 44. After the extended water tank 6 and the sealing cover 7 are installed, the second insulation shell 41 is placed over the outside of the extended water tank 6, and the insert rod 43 on it is inserted into the slot 44 on the first insulation shell 40. Finally, the insulation cover 42 is also installed together through the insert rod 43 and slot 44, thus forming a complete insulation layer, which has an insulation effect on the water storage tank 1 and the extended water tank 6, reducing heat loss. If there are multiple extended water tanks 6, select the corresponding number of second insulation shells 41 and connect them together through the insert rod 43 and slot 44. The installation process is convenient and quick.

[0020] Furthermore, as shown in the figure, in this embodiment, rotating shafts 50 are rotatably installed inside the extended water tank 6 and the storage tank 1, respectively. The two ends of the rotating shafts 50 are rotatably installed on the inner walls of the storage tank 1 or the extended water tank 6 through bearing seats. Spiral blades 51 are fixedly installed on the rotating shafts 50. The inner magnetic rotor 54 of the electromagnetic coupler is fixedly installed on the sealing cover 7. A square rod 52 is fixedly installed on the output shaft of the inner magnetic rotor 54 and one end of the rotating shaft 50, respectively. A square groove 53 is opened at the other end of the rotating shaft 50. When the square rod 52 and the square groove 53 are inserted and matched, they can drive and connect adjacent rotating shafts 50 together. A motor 55 is fixedly installed on the heat insulation cover 42. The output shaft of the motor 55 passes through the heat insulation cover 42. A through hole is opened on the heat insulation cover 42 for the output shaft of the motor 55 to pass through, and the outer magnetic rotor 56 of the electromagnetic coupler is fixedly installed. The rotating shaft 50, the spiral blades 51, the output shaft 54 ​​of the inner magnetic rotor, the outer magnetic rotor 56, and the output shaft of the motor 55 are arranged coaxially. When the extended water tank 6 is installed onto the water storage tank 1, the square rod 42 inside the extended water tank 6 is simultaneously inserted into the square groove 53 inside the water storage tank 1, thereby connecting the two rotating shafts 50 together. Similarly, the output shaft of the inner magnetic rotor 54 can also be connected to the rotating shaft 50 through the square rod 52 and the square groove 53, energizing the motor 55. The motor 55 drives the output shaft of the inner magnetic rotor 54 to rotate through the outer magnetic rotor 56, and then drives the rotating shaft 50 to rotate together through the square rod 53 and the square groove 54, thereby accelerating the upward flow of the heated water in the water storage tank 1, making the water in the extended water tank 6 and the water storage tank 1 heated more evenly, and reducing the stratification of hot and cold water.

[0021] Furthermore, as shown in the figure, the bottom of the water storage tank 1 in this embodiment is inverted conical and connected to a slag discharge pipe 60, with a sealing plug 61 threaded onto the slag discharge pipe 60. The inverted conical bottom of the water storage tank 1 allows impurities settled in the water to concentrate in one place and be discharged through the slag discharge pipe 60, making it more convenient to use.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
