[0041] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0042] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0043] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0044] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0045] Understandably, during the operation of heat pump equipment, outside air needs to be continuously introduced through the air inlet to ensure heat exchange efficiency. To prevent dust, particulate matter, and other impurities in the air from entering the heat pump equipment and causing contamination of critical components such as the heat exchanger or blockage of the air ducts, a removable filter structure is usually installed at the air inlet. However, since the filter is located inside the heat pump equipment, when users need to clean, maintain, or replace the filter, they must first remove the entire front panel to remove it. This not only increases the difficulty of filter removal and installation, reduces efficiency, but also causes many inconveniences for users during operation.

[0046] The complex disassembly and assembly process often leads users to rely on maintenance personnel to clean the filters. Furthermore, due to the tedious disassembly and assembly process, users may delay or neglect filter cleaning, resulting in filter clogging. Filter clogging significantly reduces the operating efficiency of heat pump equipment, increases energy consumption, and may even cause equipment malfunction, affecting its normal use. At the same time, frequent disassembly and assembly of the front panel can also affect the overall structural stability of the heat pump equipment, reduce its sealing performance, and further impact its performance and lifespan.

[0047] To address the aforementioned problems, some embodiments of this utility model propose a housing assembly 1000, as detailed below. Figures 1 to 10 The enclosure assembly 1000 is described as shown.

[0048] For ease of description, the following description uses a heat pump device 2000 as an example. In this embodiment of the invention, the heat pump device 2000 includes a housing assembly 1000, a first heat exchanger, a second heat exchanger, a compressor, a fan, and other components. Specifically, refer to... Figure 1 and Figure 2 As shown, in this embodiment of the utility model, the housing assembly 1000 includes a shell 100, a filter screen 200 and a cover 300. The shell 100 has a hollow structure. A first heat exchanger is disposed in the inner cavity of the shell 100, dividing the inner cavity of the shell 100 into an air inlet cavity and an air outlet cavity. Functional components such as a second heat exchanger and a compressor are disposed in the air inlet cavity, and a fan is disposed in the air outlet cavity.

[0049] Correspondingly, the surface of the outer casing 100 is provided with an air inlet 121 and an air outlet 122. The air inlet 121 communicates with the air inlet cavity, and the air outlet 122 communicates with the air outlet cavity. In this embodiment of the present invention, the air inlet cavity and the air outlet cavity together form an air duct 110, with the air inlet 121 and the air outlet 122 being the two ends of the air duct 110. The air inlet 121 and the air outlet 122 are respectively connected to the outdoor environment through pipes 600. Therefore, outdoor cold air can enter the air inlet cavity through the air inlet 121, then flow through the first heat exchanger for heat exchange, then enter the air outlet cavity, and finally return to the outdoor environment through the air outlet 122.

[0050] To reduce the risk of dust, particulate matter, and other impurities in the air entering the heat pump unit 2000, refer to... Figure 2 As shown, the filter 200 is disposed in the air inlet cavity and covers the air inlet 121. Therefore, the filter 200 can block impurities carried in the air entering the air inlet cavity through the air inlet 121. In this embodiment, the surface of the housing 100 is also provided with a mounting opening 132 for connecting the ventilation duct 110. The size and shape of the mounting opening 132 are suitable for the filter 200 to pass through. Specifically, in one example, the mounting opening 132 is located on the front side of the housing 100, thereby facilitating operation by the user in front of the heat pump device 2000.

[0051] Reference Figure 1 and Figure 2 As shown in this embodiment of the invention, during normal use, the cover 300 covers and seals the mounting opening 132, thereby ensuring the airtightness of the air duct 110. In this embodiment, the cover 300 and the outer shell 100 are detachably connected. Specifically, the cover 300 and the outer shell 100 can be connected by fasteners or by other detachable connection methods such as interference fits. This embodiment does not limit this to any particular method.

[0052] In this embodiment, when the user needs to disassemble the filter 200, the cover 300 must first be removed to expose the mounting port 132, from which the filter 200 can then be removed. Next, the cleaned filter 200 or a new filter 200 can be placed into the air duct 110 through the mounting port 132, and then the cover 300 can be reinstalled. This allows for quick disassembly and assembly of the filter 200, effectively avoiding the cumbersome steps of removing the front panel 136, simplifying the disassembly and assembly process, and reducing the operational difficulty. This not only ensures the structural stability of the heat pump equipment 2000 but also reduces reliance on professional maintenance personnel, increasing the user's willingness to replace the filter 200 themselves, thereby reducing the risk of filter 200 clogging. Furthermore, the efficiency of filter 200 disassembly and assembly is significantly improved, saving time required for filter 200 cleaning and maintenance, and improving the user experience.

[0053] Reference Figure 2 As shown, in this embodiment of the present invention, the outer casing 100 includes a chassis structure 140, side plates 130, and a top cover 120. The side plates 130 are arranged circumferentially along the top cover 120, with one end connected to the outer periphery of the top cover 120. The chassis structure 140 is connected to the other end of the side plates 130. Based on this, the chassis structure 140, side plates 130, and top cover 120 together enclose the inner cavity of the heat pump device 2000, and serve as the outer casing 100 of the heat pump device 2000. It should be noted that the chassis structure 140, side plates 130, and top cover 120 can be detachably connected. For example, the chassis structure 140, side plates 130, and top cover 120 can be connected by fasteners or by snap-fit ​​connections, etc. This embodiment does not limit this.

[0054] Continue to refer to Figure 2 As shown, in this embodiment of the present invention, the air inlet 121 and the air outlet 122 are spaced apart on the top cover 120, while the side plate 130 has an inwardly recessed mounting groove 131. Specifically, the shape and size of the mounting groove 131 match the cover 300, thereby ensuring that the cover 300 can accurately cover the mounting groove 131. The mounting opening 132 is formed in the bottom wall of the mounting groove 131 and penetrates the side plate 130, thereby communicating with the air duct 110. In one example, the air inlet 121 is located to the right of the air outlet 122, and the mounting groove 131 is formed in the right half of the front side of the side plate 130.

[0055] Combination Figure 1It is understood that in this embodiment of the present invention, when the cover 300 is installed on the mounting groove 131, the outer surface of the cover 300 is flush with the outer surface of the side plate 130, thereby ensuring the consistency of the appearance of the outer shell 100. It should be noted that the outer surface of the cover 300 refers to the end face of the cover 300 facing away from the side plate 130. Based on this, to facilitate accurate positioning and operation of the cover 300 by the user, a handle 310 is also provided on the outer surface of the cover 300, allowing the user to remove the cover 300. Specifically, the handle 310 can be a recessed groove facing the side plate 130, or a protruding rib protruding from the outer surface of the cover 300. The handle 310 provides the user with a convenient point for applying force, facilitating the removal of the cover 300.

[0056] Reference Figure 4 As shown, in this embodiment of the present invention, the side plate 130 includes two adjacent side walls, and the mounting groove 131 is formed on the adjacent two side walls of the side plate 130, with the two side walls forming an included angle with each other. The cover 300 is bent around the side plate 130 in the circumferential direction, and the two ends of the cover 300 along the circumferential direction of the side plate 130 are respectively engaged with the two side walls. Specifically, the mounting groove 131 extends to different side walls of the side plate 130. In this embodiment, a part of the mounting groove 131 is located on the front side wall of the side plate 130, and another part is located on the right side wall of the side plate 130. The cross-sectional shape of the mounting groove 131 is approximately L-shaped, providing a clear guide for the user when installing the cover 300, making it easier for the user to quickly determine the installation direction of the cover 300, thereby simplifying the installation process of the cover 300 and improving the installation efficiency of the cover 300.

[0057] Reference Figure 3 and Figure 4 As shown, in this embodiment of the present invention, one end of the cover 300 is provided with a plug-in portion 320, and the other end is provided with a fixing portion 330. The handle portion 310 is provided at the end near the fixing portion 330. The side plate 130 is provided with a locking hole 133 that matches the plug-in portion 320, and the locking hole 133 is located on one side of the mounting opening 132. It should be noted that the plug-in portion 320 can be a plug-in structure that matches the locking hole 133, such as a pin, a buckle, or other plug-in structure. The above-mentioned plug-in structure can be inserted into the locking hole 133 to achieve the pre-positioning of the cover 300.

[0058] In this embodiment of the invention, when assembling the cover 300, the insertion part 320 can be inserted into the locking hole 133. At this time, the cover 300 can rotate around the insertion point 322 under the action of external force, so that the fixing part 330 is close to the side plate 130. When the cover 300 rotates to the position that completely covers the mounting groove 131, the fixing part 330 is connected to the side plate 130, thereby realizing the installation of the cover 300. Conversely, by applying force to the handle part 310, the fixing part 330 is disengaged from the side plate 130, the cover 300 rotates around the insertion point 322, so that the fixing part 330 is away from the side plate 130, and then the insertion part 320 can be removed from the locking hole 133.

[0059] Specifically, refer to Figure 5 As shown, in this embodiment of the present invention, the insertion part 320 is constructed as a latch 321, which is bent and can be inserted into the latch hole 133. The insertion point 322 can be understood as the position where the latch 321 connects to the latch hole 133. It is understood that the bent latch 321 can serve as a guide when the cover 300 rotates around the insertion point 322.

[0060] Reference Figure 6 As shown in this embodiment of the invention, the fixing position is constructed as a first buckle 331, and the side plate 130 is provided with a first latching position 134. The first buckle 331 and the first latching position 134 can be fastened together. Based on this, when assembling the cover 300, when the cover 300 is rotated to a position that completely covers the mounting groove 131, the first latching position 134 and the first buckle 331 are fastened together, thereby realizing the quick installation of the cover 300.

[0061] Reference Figure 3 As shown in this embodiment of the invention, the latch 321 and the first latch 331 are respectively disposed on both sides of the cover 300 along its length. Since the cover 300 is generally elongated, in order to improve the connection stability between the cover 300 and the side plate 130, in this embodiment, the cover 300 is provided with second latches 340 on both sides along its width. It should be noted that the width direction of the cover 300 is consistent with the height direction of the outer shell 100. The side wall of the mounting groove 131 is provided with a second latch 135, which matches the second latch 340, and the two can achieve a latching connection. When assembling the cover 300, when the cover 300 is rotated to a position that completely covers the mounting groove 131, the first latch 134 engages with the first latch 331, and at the same time, the second latch 340 also engages with the second latch 135.

[0062] Understandably, heat pump units 2000 are typically installed indoors, utilizing the cool outdoor air as a low-temperature heat source. Through a series of heat exchange processes, they extract heat to provide hot water or indoor heating. The relatively high indoor temperature makes the cover 300 warmer than the cool air inside the outer shell 100, and this significant temperature difference easily causes condensation to form on the outer surface of the cover 300. Therefore, referring to… Figure 8 As shown in the embodiment of this utility model, an avoidance groove 350 is provided on the inner side of the cover 300. The avoidance groove 350 is formed by the end face of the cover 300 facing away from the outer shell 100.

[0063] Among them, combined Figure 3 It is understood that an insulation component 400 is provided within the clearance groove 350, and the insulation component 400 is fixed within the clearance groove 350 and connected to the cover 300. In one example, the insulation component 400 is adhered to the cover 300 using adhesive. In this embodiment, the insulation component 400 is located between the bottom wall of the clearance groove 350 and the bottom wall of the mounting groove 131, that is, one end of the insulation component 400 covers the cover 300, and the other end covers the side plate 130, thereby separating the cover 300 and the side plate 130. At the same time, the insulation component 400 also seals the mounting opening 132, preventing cold air from flowing out of the mounting opening 132, thereby reducing the possibility of condensation forming on the outer surface of the cover 300.

[0064] In one example, the insulation component 400 is made of sponge material with a minimum thickness of w, satisfying: w ≥ 5mm. It is understood that the minimum thickness of the insulation component 400 refers to the thickness of the thinnest part of the sponge. It is also understood that the inventors, through numerous experiments, discovered that if the minimum thickness of the insulation component 400 is too small, its insulation performance will be severely weakened, making its insulation capacity insufficient to meet the requirements for blocking cold transfer. Therefore, by rationally designing the range of the minimum thickness w of the insulation component 400, its insulation function can be effectively utilized to achieve the required heat insulation effect.

[0065] Reference Figure 9 As shown, in this embodiment of the present invention, the housing assembly 1000 further includes a frame 500, which is disposed between the side panel 130 and the top cover 120. Specifically, the lower end of the frame 500 is connected to the top of the side panel 130, and the upper end is connected to the top cover 120. Specifically, the frame 500 can be connected to the side panel 130 and the top cover 120 by fasteners, or by detachable methods such as snap-fit ​​connections; this embodiment does not limit this connection. Figure 10It is understood that the frame 500 is provided with a groove 510, the width of which is suitable for accommodating the filter screen 200, and its opening faces forward and is positioned opposite to the mounting port 132. Based on this, the filter screen 200 can enter the groove 510 from the mounting port 132, and the filter screen 200 is slidably connected to the frame 500, making it convenient for the user to remove or insert the filter screen 200.

[0066] Continue to refer to Figure 10 As shown, in this embodiment of the invention, the frame 500 includes a first limiting part 520 and a second limiting part 530, which are arranged alternately from top to bottom to define the slide groove 510. The first limiting part 520 and the second limiting part 530 form a limiting assembly. In this embodiment, multiple sets of limiting assemblies are provided, and these sets are arranged alternately in the front-back direction. The front side of the first limiting part 520 bends upward, while the front side of the second limiting part 530 bends downward. When the filter 200 enters the slide groove 510, the front ends of the first limiting part 520 and the second limiting part 530 guide the filter 200, reducing the possibility of the user inserting the filter 200 incorrectly and further reducing the assembly difficulty of the filter 200.

[0067] Reference Figure 2 and Figure 5 As shown in this embodiment of the invention, a gripping part 210 is provided on the front side of the filter screen 200. When disassembling the filter screen 200, the user can pull the gripping part 210 to allow the filter screen 200 to pass through the mounting port 132 after removing the cover 300. In this embodiment, the gripping part 210 is integrally formed with the filter screen 200 and extends in the same direction to avoid interference with the upper frame 500. Specifically, in this embodiment, when the filter screen 200 is inserted into the mounting port 132, the minimum distance between the filter screen 200 and the inner wall of the mounting port 132 is greater than or equal to 1 mm, thereby reducing the risk of the filter screen 200 colliding with the side plate 130.

[0068] This utility model also provides a heat pump device 2000, including the housing assembly 1000 described in the above embodiments. Specifically, the heat pump device 2000 can be a heat pump water heater or a heat pump heating system; this embodiment does not limit it in this way.

[0069] The heat pump device 2000 adopts the housing assembly 1000 of the above embodiment. An installation port 132 communicating with the air duct 110 is provided on the surface of the outer casing 100. A cover 300 is provided over the installation port 132, and the cover 300 is detachably connected to the outer casing 100. Therefore, when the cover 300 is removed, the filter 200 can pass through the installation port 132 and detach from the outer casing 100 under external force. When installing the filter 200, it can also be installed into the air duct 110 through the installation port 132, thus simplifying the filter 200's installation and removal process, achieving convenient installation and removal of the filter 200, reducing the maintenance time of the heat pump device 2000, lowering the difficulty of installing and removing the filter 200, reducing the risk of equipment damage due to improper operation, and improving the overall structural stability of the heat pump device 2000.

[0070] Since the heat pump device 2000 adopts all the technical solutions of the housing assembly 1000 of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
