[0041] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0042] In the description of the embodiments of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations on the embodiments of the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0043] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0044] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0045] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0046] 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.

[0047] The heat pump water heater in the prior art has an integral outer shell for the head assembly, which is generally a whole enclosure arranged between the upper cover and the base of the head assembly. If the head assembly fails, generally only the upper cover or the base can be removed to inspect the inside of the head assembly. However, the upper cover of the head assembly may be equipped with the inner tank of the water heater, and the internal parts of the head assembly are fixed on the base. Therefore, the integral outer shell is not conducive to the maintenance of the water heater.

[0048] See also Figures 1 to 3 The first embodiment of the utility model provides a head assembly of a heat pump water heater, including a base 100, an upper cover 200 and a surrounding plate 300, wherein the upper cover 200 is located above the base 100; the surrounding plate 300 is fixed between the base 100 and the upper cover 200 to form an installation space 350; the surrounding plate 300 is spliced ​​by at least two splicing plates 310.

[0049] The enclosure 300 is fixed between the base 100 and the upper cover 200 to form an installation space 350. The enclosure 300 plays a protective role, and the installation space 350 is used to install the internal parts of the head assembly. The enclosure 300 is spliced ​​by at least two splicing plates 310. If the internal parts of the head assembly fail, it is only necessary to remove the splicing plate 310 to check the internal condition of the head assembly without removing the entire enclosure 300, thereby saving maintenance time.

[0050] It can be understood that the enclosure 300 is formed by at least two splicing plates 310. During maintenance, at least one splicing plate 310 can be removed to view the internal condition of the head assembly. If one splicing plate 310 is removed, an inspection port is formed on the enclosure 300 for easy maintenance. After the maintenance is completed, the splicing plate 310 can be installed. During the entire maintenance process, there is no need to remove other parts such as the upper cover 200 or the base 100, nor is there any need to remove the entire enclosure 300. The operation is simple and convenient, saving time. The internal parts of the head assembly include an evaporator 800, a compressor 600, an electrical control box 900, etc. If the size of the faulty internal parts is too large, two or three splicing plates 310 can be removed as needed to form a larger inspection port on the enclosure 300, which is flexible to operate. In addition, during maintenance, the splicing plate 310 at the corresponding position can be removed for maintenance according to the specific location of the faulty internal parts, without removing the entire enclosure 300.

[0051] If a part of the enclosure 300 is damaged, it is only necessary to replace the corresponding splicing board 310; according to usage requirements, multiple identical splicing boards 310 can be assembled to form different enclosures 300, so that the shape of the enclosure 300 is more flexible and can adapt to different user needs and market demands. Using the same splicing board 310 to form different enclosures 300 can also save manufacturing costs and alleviate inventory pressure.

[0052] In one embodiment, see Figure 1 and Figure 2 A first buckling portion 400 is formed on at least one of the base 100 and the upper cover 200 , and a second buckling portion 320 is formed on the splicing plate 310 . The first buckling portion 400 and the second buckling portion 320 cooperate so that the splicing plate 310 is connected to at least one of the base 100 and the upper cover 200 .

[0053] It can be understood that the first buckle part 400 and the second buckle part 320 cooperate to facilitate the disassembly and assembly of the splicing plate 310. The splicing plate 310 directly cooperates with the base 100 or the upper cover 200, which is conducive to directly removing a single splicing plate 310 during operation without removing the entire enclosure 300. The first buckle part 400 and the second buckle part 320 cooperate to facilitate the quick removal or installation of the splicing plate 310 from the base 100 or the upper cover 200.

[0054] In one embodiment, the splicing plate 310 is provided with second buckling parts 320 on two opposite sides, the second buckling parts 320 are snap-fit ​​plates, and the first buckling parts 400 are protrusions, which are provided on the inner side of the snap-fit ​​plates.

[0055] Among them, the side of one clamping plate facing the other clamping plate is the inner side of the clamping plate; the clamping plate is abutted on the protrusion, so that the splicing plate 310 is connected to at least one of the base 100 and the upper cover 200; the matching of the slot and the buckle has high requirements for processing accuracy. In comparison, the matching between the clamping plate and the protrusion is simpler and faster, and the processing is simpler. The splicing plate 310 is provided with a second buckling part 320 on both sides opposite to each other, and two first buckling parts 400 are correspondingly provided on the upper cover 200 or the base 100. When installed, the clamping plates on both sides of the splicing plate 310 abut on the protrusion, and the tension of the plate body is used to make the clamping plate and the protrusion fit tightly. Two protrusions can be correspondingly provided on the upper cover 200, and two protrusions can be correspondingly provided on the base 100 to enhance the connection effect. The embodiment of the utility model also includes a fastening screw, a screw hole can be provided at one end of the protrusion, and a perforation is correspondingly provided on the clamping plate, and the fastening screw passes through the perforation and is connected with the screw hole to fix the splicing plate 310.

[0056] In one embodiment, see Figure 1 The splicing plate 310 is arc-shaped, and the two clamping plates are arranged on both sides of the bending direction of the splicing plate 310.

[0057] The tension of the arc-shaped splicing plate 310 allows the clamping plate to be firmly connected to at least one of the base 100 and the upper cover 200. In addition, the arc-shaped splicing plate 310 connection is conducive to the enclosure 300 forming a cylindrical shape. Compared with other shapes, the volume of the cylindrical shape is larger when the surface area is the same. Therefore, the enclosure 300 is cylindrical, which is conducive to saving the material of the enclosure 300.

[0058] In one embodiment, see Figure 1 , Figure 2 and Figure 4 The splicing plate 310 includes a first splicing plate 311 and a second splicing plate 312. The first splicing plate 311 is provided with a first hanging hole 3111, and the second splicing plate 312 is provided with a first hook 3121 corresponding to the first hanging hole 3111; the first hanging hole 3111 and the first hook 3121 move relative to each other for hanging and fixing.

[0059] Through the cooperation of the first hook 3121 and the first hanging hole 3111, the splicing plates 310 are tightly connected; the first hanging hole 3111 and the first hook 3121 move relative to each other to hang and fix, so that the second splicing plate 312 cooperates with the base 100 or the upper cover 200, and the first hook 3121 and the first hanging hole 3111 play a positioning role, which is convenient for connecting the second splicing plate 312 with the first splicing plate 311. At the same time, by identifying the first hook 3121 and the first hanging hole 3111, the installation position and installation direction of the second splicing plate 312 can be determined to avoid installation errors. For example, one first splicing plate 311 can be set, and two second splicing plates 312 can be set, the first hanging holes 3111 are set on both sides of the first splicing plate 311, and the first hook 3121 is set at one end of the second splicing plate 312. Through the cooperation of the first hook 3121 and the first hook 3121, the first splicing plate 311 is connected to the two second splicing plates 312 respectively.

[0060] In one embodiment, see Figure 5 The head assembly also includes at least two columns 500, which are connected to the base 100 and the upper cover 200; the two ends of the enclosure 300 are respectively fixed on two adjacent columns 500, and an operating port 330 is formed between the two columns 500, and the operating port 330 is suitable for operating the valve body installed in the installation space 350.

[0061] The column 500 is connected to the base 100 and the upper cover 200, and the column 500 plays a connecting role; the two ends of the enclosure 300 are respectively fixed on two adjacent columns 500 to form an operating port 330; the column 500 can support the enclosure 300 to prevent the enclosure 300 from being deformed by force, and the valve body installed in the installation space 350 is controlled through the operating port 330 to improve flexibility.

[0062] In one embodiment, see Figure 4 and Figure 5 One of the column 500 and the enclosure 300 is provided with a second hook 3122, and the other is provided with a second hanging hole 510 corresponding to the second hook 3122; the second hanging hole 510 and the second hook 3122 move relative to each other for hanging and fixing.

[0063] By cooperating with the second hook 3122 and the second hanging hole 510, the enclosure 300 is tightly connected to the column 500; the second hanging hole 510 and the second hook 3122 move relative to each other for hanging and fixing, so that the enclosure 300 cooperates with the base 100 or the upper cover 200, and the second hook 3122 and the second hanging hole 510 play a positioning role, which facilitates the connection of the second splicing plate 312 with the second splicing plate 312. At the same time, by identifying the second hook 3122 and the second hanging hole 510, the installation position of the enclosure 300 can be determined to avoid installation errors. The second hook 3122 can be set on the enclosure 300. During installation, it is convenient to align the second hook 3122 with the second hanging hole 510 on the column 500; for example, the first hook 3121 is set at one end of the second splicing plate 312, and the second hook 3122 is set at the other end. During installation, the first splicing plate 311 is installed first, the first hook 3121 is aligned with the first hanging hole 3111, the second hook 3122 is aligned with the second hanging hole 510, and the second splicing plate 312 is moved to realize the installation of the second splicing plate 312. At the same time, the second splicing plate 312 is connected to the two ends of the first splicing plate 311 to form the enclosure 300.

[0064] See also Figure 4 In order to better fix the second splicing plate 312, in one embodiment, a bending portion 3123 is formed at one end of the second splicing plate 312, and the bending portion 3123 is buckled with the opening of the operation port 330 to prevent the enclosure 300 from being disengaged from the column 500. The second hook 3122 can be arranged on the inner side of the bending portion 3123 to achieve a better connection effect.

[0065] See also Figures 2 to 4 In one embodiment, the bottom of the enclosure 300 is provided with an abutment plate 340, which abuts against the lower end of the base 100. The abutment plate 340 cooperates with the base 100 to further fix the splicing plate 310; a perforation may be provided on the abutment plate 340, and a threaded hole may be provided correspondingly at the lower end of the base 100, and the abutment plate 340 may be fixed to the lower end of the base 100 by tightening screws; the abutment plate 340 is connected to the lower end of the base 100, which is relatively easy to hide; in order to prevent the abutment plate 340 from protruding from the lower end of the base 100, a matching step 110 may be provided at the lower end of the base 100, and the abutment plate 340 cooperates with the matching step 110 to prevent the abutment plate 340 from protruding; the abutment plate 340 may be flush with the lower end surface of the base 100, thereby improving the flatness of the surface of the head assembly.

[0066] In one embodiment, see Figure 1 A locking step 210 is provided at the lower end of the upper cover 200 , and the upper end of the enclosure 300 cooperates with the locking step 210 .

[0067] The upper cover 200 is flush with the enclosing plate 300 by the cooperation with the engaging step 210, thereby improving the flatness of the surface of the head assembly. It can be understood that the upper end of the splicing plate 310 cooperates with the engaging step 210, and the abutting plate 340 at the bottom of the splicing plate 310 abuts against the lower end of the base 100 to achieve the installation of the splicing plate 310. Please refer to Figure 1 and Figure 2 , a matching plate 360 ​​can be provided at the upper end of the splicing plate 310 to facilitate the matching of the splicing plate 310 with the engaging step 210. The matching plate 360, the abutting plate 340 and the engaging plates located on both sides of the splicing plate 310 are connected to facilitate processing; an avoidance hole can be provided on the matching plate 360 ​​to avoid the column 500 connecting the upper cover 200 and the base 100; Figure 1 and Figure 4 As shown, the second splicing plate 312 is provided with an avoidance recess 3124 on one side close to the first splicing plate 311, and the avoidance recess 3124 is provided corresponding to the first buckle portion 400 to avoid the fastening screws fixing the first splicing plate 311. A display screen can be provided on the enclosure 300 to display the working status of the head assembly.

[0068] See also Figure 1 , Figure 6 and Figure 7 The head assembly of the heat pump water heater of the embodiment of the utility model further includes a partition 710, which is arranged in the installation space 350. The partition 710 is suitable for isolating the internal parts of the head assembly to prevent the various parts from interfering with each other. For example, as internal parts of the head assembly, the air duct 720 and the compressor 600 do not need to be directly connected, and the air supply work of the air duct 720 is easy to affect the normal operation of the compressor 600. If the air duct 720 is damaged, it will have a direct impact on the operation of the compressor 600; the compressor 600 and the air duct 720 can be isolated by the partition 710 to prevent the two from interfering with each other.

[0069] like Figure 3 , Figure 6 and Figure 7 As shown, since the operating port 330 is provided on the enclosure 300, the parts located in the installation space 350 can be directly seen through the operating port 330, and at least one end of the partition 710 is connected to the opening of the operating port 330, and the internal parts of the head assembly, such as the compressor 600, are arranged in the space between the partition 710 and the enclosure 300, and the partition 710 plays a shielding role. The partition 710 can be provided with an avoidance groove to avoid the valve body or the electric control box 900 and other parts installed in the installation space 350. The top and bottom of the partition 710 are respectively provided with an insertion strip 760, and the upper cover 200 and the base 100 are correspondingly provided with a slot, and the partition 710 is fixed by the cooperation of the insertion strip 760 and the slot.

[0070] like Figure 6 As shown, the head assembly of the heat pump water heater of the embodiment of the utility model further includes an air duct 720 and a fan bracket 730; the air duct 720 is mounted on the fan bracket 730; the partition 710 and the fan bracket 730 are connected to form a receiving space 740 of the air duct 720. Since the air duct 720 needs to be connected to the outside, the air duct 720 is separately arranged in the receiving space 740 to facilitate the maintenance of the air duct 720.

[0071] The second aspect of the present invention also provides a heat pump water heater, including a head assembly of the heat pump water heater.

Its specific implementation method can refer to the above embodiments, and this application will not go into details.

[0073] 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.
