[0045] Heat pump water heaters, also known as "air source heat pump water heaters" and "air energy water heaters", absorb low-temperature heat from the air, gasify the refrigerant in the evaporator, and turn it into low-temperature steam. The low-temperature steam is then compressed by a compressor and converted into high-temperature, high-pressure gas, and then the compressed high-temperature heat is converted into water heating by a heat exchanger. Therefore, compared with traditional electric water heaters and gas water heaters, heat pump water heaters have many advantages such as high efficiency, energy saving, environmental protection, and safety.

[0046] Since the fan will vibrate when it is working, it needs to be firmly installed on the base during installation to prevent its operating components from loosening. Therefore, when disassembling and repairing the fan, it is very laborious to remove the fan, and the outer casing needs to be removed before disassembling the fan, which is a cumbersome process.

[0047] See also Figures 1 to 2 The first aspect of the utility model provides a head assembly of a heat pump water heater, including a base 100, a fan bracket 200 and a fan 300, wherein the fan 300 is installed on the fan bracket 200; the base 100 is formed with a disassembly hole 111 of the fan bracket 200, and the fan bracket 200 can be detachably installed on the base 100.

[0048] The fan bracket 200 is used to fix the fan 300. When the fan 300 needs to be disassembled, the fan bracket 200 can be directly disassembled; the base 100 is formed with a disassembly hole 111 of the fan bracket 200. The fan bracket 200 can be disassembled and installed through the disassembly hole 111 of the base 100 without disassembling the entire machine.

[0049] It is understandable that the fan 300, as the air supply system in the heat pump water heater, is related to the normal operation of the heat pump water heater and is easy to be damaged. The disassembly hole 111 of the fan bracket 200 can be used to carry out targeted maintenance or regular inspection of the fan 300, thereby improving the safety of the heat pump water heater. Furthermore, the disassembly hole 111 is set on the base 100, which is easier to hide and does not affect the overall appearance. The fan 300 includes at least blades and a motor to achieve the air supply function.

[0050] It can be understood that the fan 300 is installed on the fan bracket 200. When repairing the fan 300, the fan bracket 200 can be directly disassembled without separately disassembling the fan 300, so as to avoid the screws and other fixings that fix the fan 300 from loosening after multiple disassembly and assembly, thereby affecting the normal operation of the fan 300. After disassembling the fan bracket 200, the fan bracket 200 still serves as the support of the fan 300, and the fan 300 can be directly repaired or inspected on the fan bracket 200. At the same time, due to the supporting effect of the fan bracket 200, the fan 300 can be The fan 300 can be directly placed on a table or the ground for repair, which is easy to operate; furthermore, during the disassembly process, the fan 300 will not be directly operated, thereby preventing the fan 300 from being damaged during the disassembly process; since the disassembly hole 111 is set on the base 100, and the fan 300 is installed on the fan bracket 200, if the fan 300 is directly removed from the disassembly hole 111, the fan bracket 200 needs to be avoided, and the disassembly and assembly is very troublesome. Therefore, the fan bracket 200 can be detachably installed on the base 100, and the fan bracket 200 can be directly disassembled and assembled.

[0051] It can be understood that, generally, the base 100 is a base, the inner tank of the water heater is arranged at the upper end of the head assembly, and a disassembly hole 111 is opened at the lower end of the base to realize the disassembly of the fan bracket 200 from the lower end of the base; the base 100 can also be a top seat, the inner tank of the water heater is arranged at the lower end of the head assembly, and a disassembly hole 111 is opened at the upper end of the top seat to realize the disassembly of the fan bracket 200 from the upper end of the top seat; or, in some embodiments, the base 100 can also have a side wall, and the disassembly hole 111 is arranged on the side wall. Regardless of whether the inner tank of the water heater is arranged at the upper end or the lower end of the head assembly, the fan bracket 200 can be disassembled and assembled.

[0052] In one embodiment, see Figure 3 The fan support 200 includes a bottom plate 210 , and the bottom plate 210 is connected to the bottom of the base 100 .

[0053] The bottom plate 210 is connected to the lower end of the base 100, and can be easily disassembled and assembled from the lower end of the base 100. The bottom plate 210 serves as the bottom support of the fan bracket 200 and has a relatively good bearing capacity. The bottom plate 210 is connected to the base 100 to more firmly fix the fan bracket 200. When disassembling, the fan bracket 200 can be taken out by holding the bottom plate 210, which is convenient to operate. A support rod 212 can be provided on the bottom plate 210, and the support rod 212 is used to fix the fan 300.

[0054] In one embodiment, see Figure 2 and Figure 3, the edge of the disassembly hole 111 forms a fixed step 130; the edge of the bottom plate 210 matches the fixed step 130, and the fan bracket 200 can be disassembled and installed from the disassembly hole 111 at the bottom of the base 100 through the cooperation between the bottom plate 210 and the fixed step 130, so as to prevent the fan bracket 200 from shifting after installation. At the same time, the bottom plate 210 of the fan bracket 200 can be engaged with the fixed step 130 to prevent the fan bracket 200 from protruding from the lower end of the base 100; the bottom plate 210 of the fan bracket 200 can be flush with the lower end of the base 100, making the overall structure more compact.

[0055] In one embodiment, see Figure 2 A positioning column 131 is provided on the fixed step 130 , a positioning hole 211 is provided on the bottom plate 210 , and the positioning column 131 passes through the positioning hole 211 .

[0056] The positioning column 131 can guide the installation of the fan bracket 200 so that the fan bracket 200 is installed at a correct installation position. At the same time, the cooperation between the positioning hole 211 and the positioning column 131 can prevent the fan bracket 200 from shifting after installation.

[0057] See also Figure 4 The head assembly of the heat pump water heater of the embodiment of the utility model also includes an evaporator 500. The evaporator 500 is bent to form an installation cavity 510 for the fan 300, which can save space and make the structure of the water heater more compact. The fan 300 works inside the installation cavity 510, which can drive the air circulation in the installation cavity 510, that is, drive the air flow on the surface of the evaporator 500, so as to improve the heat exchange effect between the air and the evaporator 500 and enhance the absorption of external heat by the evaporator 500.

[0058] In one embodiment, see Figure 3 and Figure 4 The edge of the bottom plate 210 of the fan bracket 200 is arc-shaped corresponding to the evaporator 500 , and correspondingly, the fixing step 130 is arc-shaped, so that the bottom plate 210 forms the bottom of the installation cavity 510 , so that the fan 300 located on the bottom plate 210 is installed in the installation cavity 510 .

[0059] In one embodiment, see Figure 2 The base 100 includes a base body 110 and a base body cover 120 , a disassembly hole 111 is formed in the base body 110 , and the base body cover 120 can be detachably installed in the disassembly hole 111 .

[0060] The seat cover 120 can be detachably mounted on the disassembly hole 111, and the seat cover 120 can realize the opening and closing of the disassembly hole 111; the shape of the seat cover 120 can match the disassembly hole 111 so as to close the disassembly hole 111; the shape of the seat cover 120 can also not match the disassembly hole 111, and the disassembly hole 111 can be opened and closed by disassembling the seat cover 120; the seat cover 120 can be directly connected to the base or indirectly connected to the base, for example, the seat cover 120 can be installed on the fan bracket 200. Alternatively, in some embodiments, the seat cover 120 can be rotatably connected to the base 110, and the disassembly hole 111 can be opened and closed by rotating the seat cover 120.

[0061] In one embodiment, see Figure 2 The seat body 110 forms a disassembly notch 112, and the disassembly notch 112 is located above the seat body cover 120. When disassembling the seat body cover 120, it is only necessary to buckle a finger on the disassembly notch 112 and pry the seat body cover 120 to complete the disassembly.

[0062] It is understandable that the disassembly notch 112 can be connected to the disassembly hole 111 for easy processing; the disassembly notch 112 can also be not connected to the disassembly hole 111, and only needs to be located above the seat cover 120. The disassembly notch 112 can be set at the edge of the seat cover 120 for easy processing, and the seat cover 120 can be removed from the edge of the seat cover 120, which conforms to the general operating habits of users.

[0063] The head assembly of the heat pump water heater of the utility model embodiment can be seen in Figure 5 , and also includes an upper cover 700 and a panel 800. The upper cover 700 is located above the base 100; the panel 800 is fixed between the base 100 and the upper cover 700 to form an installation space; an operation port 810 is provided on the panel 800, and the operation port 810 is suitable for operating the valve body installed in the installation space. With the operation port 810, a semi-open space structure is formed inside the head assembly. Through the operation port 810, some components in the panel 800, such as the valve body, can be operated to improve flexibility.

[0064] In one embodiment, see Figure 5The disassembly notch 112 can be connected to the top of the base 100, and while facilitating processing, the size of the disassembly notch 112 is increased to facilitate the insertion of fingers to remove the seat cover 120; or, in some embodiments, the disassembly notch 112 can be connected to the operating port 810. In order to operate the valve body installed in the installation space, the size of the operating port 810 is relatively large. Therefore, if the disassembly notch 112 is connected to the operating port 810, the operator can place his hand directly on the operating port 810, extend his fingers to the disassembly notch 112, and apply force to the seat cover 120 to complete the disassembly; the disassembly notch 112 can be connected to the top of the base 100, and is set corresponding to the operating port 810. When removing the seat cover 120, part of the space of the operating port 810 can be borrowed to improve the flexibility of removing the seat cover 120.

[0065] In one embodiment, see Figure 2 and Figure 6 A first engaging portion 113 is provided at the opening of the disassembly hole 111 , and a second engaging portion 121 is provided on the seat cover 120 . The first engaging portion 113 is at least partially engaged with the second engaging portion 121 .

[0066] It can be understood that the first interlocking portion 113 is at least partially interlocked with the second interlocking portion 121 to improve the fit between the cover seat 120 and the disassembly hole 111; the first interlocking portion 113 can be a complex structure, such as a stepped structure, a snap-on structure, etc. Of course, the utility model does not limit the structure of the first interlocking portion 113, and the first interlocking portion 113 can be at least partially interlocked with the second interlocking portion 121.

[0067] In one embodiment, see Figure 7 The lower end of the base 100 forms a grip portion 140. The grip portion 140 is used as a gripping position for fingers to facilitate carrying and prevent sliding. The grip portion 140 can be a groove for easy entry of fingers. The grip portion 140 is arranged on the covering gap between the base cover 120 and the base 110 to facilitate positioning of the base cover 120 during installation.

[0068] In one embodiment, see Figure 8 The fan bracket 200 is provided with a wire clip 220 on a side facing the evaporator 500 , and an end of the wire clip 220 forms an arc shape that is bent away from the evaporator 500 .

[0069] It can be understood that the fan 300 is installed in the installation cavity 510 formed by the bend of the evaporator 500. Since the fan 300 is connected to the wires, the distance between the fan 300 and the evaporator 500 is relatively close, and the wires are easy to touch the evaporator 500, affecting the normal operation of the evaporator 500 or causing a safety accident. The wire clip 220 is provided to guide the routing of the wires and prevent the wires from touching the evaporator 500. In general, there is one wire clip 220 to facilitate the guiding of the wires. Of course, it is not ruled out that the wire clip 220 is provided in two or three forms to enhance the wire effect.

[0070] In one embodiment, see Figure 8 Two columns 600 are fixed on the base 100, and the two ends of the evaporator 500 are fixed to the two columns 600 respectively; the columns 600 are provided with threading holes 610, and the threading holes 610 are suitable for the wires to pass through. The wires of the fan 300 pass through the wire buckle 220, and then pass through the installation cavity 510 through the threading holes 610 to connect with the power supply.

[0071] In one embodiment, see Figure 8 The threading hole 610 forms a stop protrusion 620 on the side facing the evaporator 500, and the stop protrusion 620 is used to further prevent the wire from hitting the evaporator 500; the stop protrusion 620 can be a convex block or an arc sheet bent toward the evaporator 500.

[0072] The second aspect of the present invention also provides a heat pump water heater, including a head assembly of the heat pump water heater.

[0073] It can be understood that if the head assembly of the heat pump water heater has the beneficial effects of the above embodiments, then the heat pump water heater correspondingly has the beneficial effects of the above embodiments. Its specific implementation method can refer to the above embodiments, and this application will not go into details.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
