[0028] The heat pump water heater provided in the embodiment of the present invention comprises a water tank assembly and a head assembly, wherein the water tank assembly is located below the head assembly and is assembled with the head assembly. Figures 1 to 4 As shown, the head assembly includes: a supporting base 100, which is fixed to the upper part of the water tank assembly; an air duct lower cover 200, which is located above the supporting base 100 and fixed to the supporting base 100; and an air duct upper cover module 300, which includes an air duct upper cover 310, a motor 320 and a wind wheel 330. The air duct upper cover 310 is located on the side of the air duct lower cover 200 away from the supporting base 100 (that is, the air duct upper cover 310 is located above the air duct lower cover 200) and is fixed to the air duct lower cover 200 facing the supporting base 100 (that is, from top to bottom), the motor 320 is fixed to the air duct upper cover 310, and the wind wheel 330 is located in the air duct upper cover 310 and is drivingly connected to the rotating shaft of the motor 320.

[0029] When the motor 320 of the heat pump water heater is damaged, there is no need to disassemble the heat pump water heater from the wall on which it is mounted. It is only necessary to disassemble the air duct cover module 300 from bottom to top on the head assembly, and then disassemble the air duct cover module 300 on the ground to disassemble the motor 320. The process of disassembling and assembling the motor 320 is simple and easy.

[0030] In some embodiments, Figures 1 to 3 As shown, the air duct upper cover 310 is provided with a through hole, and the air duct lower cover 200 is provided with a screw hole, the through hole is located on the side of the screw hole away from the supporting base 100 (that is, the through hole is located above the screw hole), and the threaded section of the screw passes through the through hole from the side of the air duct upper cover 310 away from the air duct lower cover 200 and is screwed into the screw hole (that is, the threaded end of the screw passes through the through hole from top to bottom and is screwed into the screw hole), so that the air duct upper cover 310 is fixed to the air duct lower cover 200 from top to bottom. This solution has a simple structure, mature technology, and high connection strength.

[0031] Of course, the duct upper cover 310 and the duct lower cover 200 may also be connected by a snap-on connection or the like, which can also achieve the purpose of this application. The purpose does not deviate from the design concept of the present invention and will not be repeated here, and should also fall within the scope of protection of this application.

[0032] In some embodiments, Figures 1 to 4As shown, the motor 320 is located in the air duct upper cover 310, so that the air duct upper cover module 300 has a more compact structure and occupies less space. The motor 320 is fixed in the air duct upper cover 310 by screws, and a shock-absorbing pad can be set between the motor 320 and the air duct upper cover 310 to reduce vibration and noise.

[0033] In some exemplary embodiments, Figures 1 to 3 As shown, the head assembly also includes: a decorative cover, which is installed outside the air duct upper cover module 300 and the air duct lower cover 200 to improve the aesthetics of the heat pump water heater. When the motor 320 of the heat pump water heater is damaged, it is not necessary to disassemble the heat pump water heater on the wall where it is mounted. It is only necessary to disassemble the decorative cover first, and then disassemble the air duct upper cover module 300 from bottom to top, and then disassemble the air duct upper cover module 300 on the ground to disassemble the motor 320. The process of disassembling and assembling the motor 320 is simple and easy.

[0034] In some examples, such as Figures 1 to 3 As shown, the decorative cover includes: a peripheral wall 500, which is sleeved on the air duct upper cover module 300 and the air duct lower cover 200; and an end cover 400, which is located at one end of the peripheral wall 500 away from the supporting substrate 100 and is detachably connected to the peripheral wall 500. The peripheral wall 500 may be set as an integral structure; or it may be, as shown in FIG. Figures 1 to 3 As shown, the peripheral wall 500 is configured as a split structure, etc.; the above can achieve the purpose of this application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the protection scope of this application.

[0035] When the motor 320 of the heat pump water heater is damaged, there is no need to disassemble the heat pump water heater from the wall mounting. It is only necessary to disassemble the lower end cover first, and then disassemble the air duct upper cover module 300 from bottom to top, and then disassemble the air duct upper cover module 300 on the ground to disassemble the motor 320. The process of disassembling and assembling the motor 320 is simple and easy.

[0036] In some embodiments, Figures 1 to 3 As shown, the duct upper cover 310 and the duct lower cover 200 are combined to form a through-wind duct, and the end cover 400 is provided with a first air port 410 and a second air port 420. The outlet 311 of the through-wind duct is connected to the outside of the decorative cover through the first air port 410, and the inlet of the through-wind duct is connected to the outside of the decorative cover through the second air port 420. Figures 1 to 3As shown, the head assembly further includes: a heat exchanger 600, which is located between the inlet of the air duct and the second air outlet 420 and fixed to the carrier base 100; a compressor and a control module, which are located on the side of the heat exchanger 600 away from the air duct and fixed to the carrier base 100. Among them, the outlet 311 of the air duct is located on the upper part of the air duct upper cover 310, and the side of the air duct upper cover 310 facing the heat exchanger 600 and the side of the air duct lower cover 200 facing the heat exchanger 600 together enclose the inlet of the air duct.

[0037] The outside air enters the decorative cover, and then passes through the second air outlet 420 and the heat exchanger 600 in sequence, and enters the through-wind duct from the inlet of the through-wind duct. After passing through the through-wind duct, it is discharged to the outside from the outlet 311 of the through-wind duct through the first air outlet 410. In the process of passing through the heat exchanger 600, the air takes away the cold energy of the heat exchanger 600.

[0038] In some embodiments, Figure 1 and Figure 3 As shown, the supporting base 100 is configured as a water receiving tray, and the water receiving tray is used to receive condensed water flowing down from the surface of the heat exchanger 600 .
