Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0024] The heat pump water heater head assembly provided in this application embodiment, such as... Figures 1 to 4 As shown, it includes: a main body, the peripheral wall 110 of which is provided with an inspection port 111; and a cover assembly, the cover assembly being installed on the outer side of the main body at the inspection port 111.

[0025] The machine head assembly has an inspection port 111 on the peripheral wall 110 of the main body. The cover assembly is installed on the outer side of the main body at the inspection port 111. When the parts inside the machine head assembly need to be repaired, the cover assembly can be removed from the outer side of the main body to repair the parts inside the machine head assembly through the inspection port 111. This operation is simple and easy.

[0026] In some examples, such as Figures 1 to 4 As shown, the machine head assembly also includes an electrical control box 300, which is installed inside the main body and faces the inspection port 111. When the electrical control box 300 malfunctions, the cover assembly can be removed from the outside of the main body to inspect the electrical control box 300 through the inspection port 111. This operation is simple and easy to perform.

[0027] In some embodiments, such as Figures 1 to 4 As shown, the circumferential dimension of the access port 111 in the main body is 'a', and its axial dimension in the main body is 'b'. The circumferential dimension of the electrical control box 300 in the main body is 'c'. At least one of a and b is greater than c to ensure that the electrical control box 300 can be removed from the access port 111. When repairing other parts inside the main body, the electrical control box 300 is removed first, so that the electrical control box 300 will not interfere with the repair process of other parts. Preferably, both a and b are set to be greater than c.

[0028] In some embodiments, such as Figure 2 and Figure 3As shown, the electrical control box 300 includes: a base box 310, which is erected inside the main body, with its opening facing the inspection port 111; an electrical control board 320, which is disposed inside the base box 310; and a cover 330, which is installed on the side of the base box 310 facing the inspection port 111. When the electrical control box 300 malfunctions, the cover assembly can be removed from the outside of the main body, and then the cover 330 can be removed through the inspection port 111 to inspect the electrical control board 320. This operation is simple and easy to perform.

[0029] In some embodiments, such as Figure 2 and Figure 3 As shown, the cover 330 is provided with a clearance hole 331. The electrical control box 300 also includes a heat dissipation device 340. One end of the heat dissipation device 340 is connected to the electrical control board 320, and the other end passes through the clearance hole 331 and extends to the side of the cover 330 facing the inspection port 111. The heat dissipation device 340 is used to enhance the heat dissipation of the electrical control board 320, thereby improving the heat dissipation effect of the electrical control board 320. The heat dissipation device 340 is configured as heat dissipation fins.

[0030] In some embodiments, such as Figures 1 to 4 As shown, the cover assembly includes: a cover 210, which is mounted on the outer side of the main body at the access port 111, and the cover 210 is provided with an installation port 211, which is opposite to the access port 111; and a wired controller 220, which is located at the installation port 211 and electrically connected to the control board 320.

[0031] In some embodiments, such as Figures 1 to 4 As shown, the main body includes: a shell, with an inspection port 111 at the front of the shell's peripheral wall 110; a fan assembly 400 and a heat exchanger 500, both housed within the shell. When the fan assembly 400 malfunctions, the cover assembly can be removed from the outside of the main body, allowing inspection of the fan assembly 400 through the inspection port 111 (to determine if the fan assembly 400 is damaged). This operation is simple and easy to perform.

[0032] Among them, such as Figures 1 to 3 As shown, the top wall of the housing is provided with a first air vent 131, and the peripheral wall 110 of the housing is also provided with a second air vent 112. The heat exchanger 500 is arranged opposite to the second air vent 112. The main body also includes an air guide ring 600, which is located inside the housing and located at the first air vent 131. The fan assembly 400 is located inside the air guide ring 600 and is configured to form an airflow that flows from the second air vent 112 through the heat exchanger 500, the electrical control box 300, and the air guide ring 600 to the first air vent 131. As the airflow passes through the heat dissipation device 340, it carries away the heat on the heat dissipation device 340, thereby enhancing the heat dissipation of the electrical control box 300. Figures 1 to 3As shown, the housing includes a water receiving tray 120, a top cover 130, and an annular peripheral wall 110. The first air outlet 131 is located on the top cover 130 (the top cover 130 includes the top wall of the housing). When the fan assembly 400 is damaged, the top cover 130 of the housing can be removed, and thus the fan assembly 400 can be replaced. This operation process is simple and easy. In addition, the peripheral wall 110 and the water receiving tray 120 can be connected by a plurality of screws. In this solution, during the maintenance process of the parts inside the head assembly (including the electronic control box), since it is no longer necessary to disassemble and assemble the peripheral wall 110, there is no need to consider the problem that the side wall blocks the screws and makes the screws impossible to disassemble and assemble.

[0033] The heat pump water heater (not shown in the figure) provided by the embodiment of the present application includes the head assembly of the heat pump water heater described in any one of the above embodiments.

[0034] This heat pump water heater has all the advantages of the head assembly of the heat pump water heater provided in any one of the above embodiments, and will not be elaborated here.

[0035] In summary, for the technical solution provided by the embodiment of the present application, the peripheral wall of the main body is provided with a maintenance opening, and the cover body assembly is covered at the maintenance opening from the outside of the main body. When the parts inside the head assembly need to be maintained, only the cover body assembly needs to be removed from the outside of the main body, and then the parts inside the head assembly can be maintained through the maintenance opening. This operation process is simple and easy.
