[0039] 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.

[0040] 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 accompanying 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] To address the aforementioned problems, some embodiments of this utility model propose a housing assembly 1000, as detailed below. Figures 1 to 12 The enclosure assembly 1000 is described as shown.

[0046] For ease of description, a heat pump device will be used as an example in the following description. In this embodiment of the invention, the heat pump device 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 , Figure 2 and Figure 3 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.

[0047] 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, with the air inlet 121 and the air outlet 122 being the two ends of the air duct. The air inlet 121 and the air outlet 122 are respectively connected to the outdoor environment through pipes. 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.

[0048] To reduce the risk of dust, particulate matter, and other impurities in the air entering the heat pump equipment, a filter 200 is installed in the air inlet cavity and covers the air inlet 121. Therefore, the filter 200 can block impurities carried by the air entering the air inlet cavity through the air inlet 121. (Refer to...) Figure 3 As shown, in this embodiment, the surface of the housing 100 is also provided with a mounting port 113 for connecting the ventilation duct. The size and shape of the mounting port 113 are suitable for the filter 200 to pass through. Specifically, in one example, the mounting port 113 is located on the front side of the housing 100, thereby facilitating operation by the user in front of the heat pump device.

[0049] Reference Figure 2 and Figure 3 As shown, in this embodiment of the present invention, during normal use, the cover 300 covers and seals the mounting opening 113, thereby ensuring the airtightness of the air duct. In this embodiment, one end of the cover 300 is rotatably connected to the outer shell 100, and the other end is detachably connected to the outer shell 100. For ease of description, the following description uses the example of the left side of the cover 300 being detachably connected to the outer shell 100, and the right side of the cover 300 being rotatably connected to the outer shell 100. Specifically, the left side of the cover 300 can be connected to the outer shell 100 by fasteners, or by other detachable connection methods such as interference fit; this embodiment does not limit this. The right side of the cover 300 can be rotatably connected to the outer shell 100 through a hinge structure or a pivot structure. Based on this, the cover 300 can rotate around its connection point with the outer shell 100, facing or away from the outer shell 100, that is, the left end of the cover 300 can rotate forward or backward.

[0050] Understandably, in one example, the housing 100 includes a front panel 111. For ease of description, the following explanation will use the example of the cover 300 being positioned on the front panel 111. (Refer to...) Figure 3 As shown, when the user needs to disassemble the filter 200, the left side of the cover 300 must first be disconnected from the outer casing 100, and the left side of the cover 300 should be rotated to face forward, thereby exposing the mounting port 113. The filter 200 can then be removed from the mounting port 113. Next, the cleaned filter 200 or another new filter 200 can be placed into the air duct through the mounting port 113, and the left side of the cover 300 should be rotated to face backward so that it covers the mounting port 113. Finally, the left side of the cover 300 should be reconnected to the outer casing 100 to complete the closure of the mounting port 113.

[0051] Obviously, in this embodiment of the present invention, when disassembling or installing the filter 200, it is only necessary to disconnect one end of the cover 300 from the outer shell 100 and rotate it away from the outer shell 100 to expose the installation port 113 for disassembly and assembly of the filter 200. This effectively avoids the cumbersome steps of disassembling the front panel 111 required for disassembly and assembly of the filter 200. This not only simplifies the disassembly and assembly process of the filter 200 and reduces the difficulty of disassembly and assembly, but also improves the efficiency of disassembly and assembly of the filter 200 and saves time required for cleaning and maintenance of the filter 200. In addition, during the disassembly and assembly of the filter 200, the cover 300 remains fixed on the outer shell 100, thereby avoiding the possibility of loss of the cover 300 due to complete disassembly and preventing positioning deviation of the cover 300 during reassembly. This ensures the smoothness of the installation of the cover 300 and the sealing of the outer shell 100, thereby improving the user experience.

[0052] Reference Figure 1As shown, in this embodiment of the present invention, the outer casing 100 includes a chassis structure 130, side plates 110, and a top cover 120. The side plates 110 are arranged circumferentially along the top cover 120, with one end connected to the outer periphery of the top cover 120. The chassis structure 130 is connected to the other end of the side plates 110. Based on this, the chassis structure 130, side plates 110, and top cover 120 together enclose the inner cavity of the heat pump device, and the chassis structure 130, side plates 110, and top cover 120 serve as the outer casing 100 of the heat pump device. It should be noted that the chassis structure 130, side plates 110, and top cover 120 can be detachably connected. For example, the chassis structure 130, side plates 110, and top cover 120 can be connected by fasteners or by snap-fit ​​connections, etc. This embodiment does not limit this.

[0053] Reference Figure 1 and Figure 3 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 surface of the side plate 110 is provided with an inwardly recessed mounting groove 112. Specifically, the shape and size of the mounting groove 112 match the cover 300, thereby ensuring that the cover 300 can accurately cover the mounting groove 112. The mounting opening 113 is formed in the bottom wall of the mounting groove 112 and penetrates the side plate 110, thereby communicating with the air duct. In one example, refer to... Figure 1 As shown, the air inlet 121 is located to the right of the air outlet 122; refer to Figure 10 As shown, the mounting groove 112 is located on the right half of the front side of the side plate 110.

[0054] Combination Figure 2 It is understood that, in this embodiment of the present invention, when the cover 300 is installed on the mounting groove 112, the outer surface of the cover 300 is flush with the outer surface of the side plate 110, 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 110.

[0055] Reference Figure 3 As shown, in this embodiment of the invention, a locking hole 114 is provided on the left side of the mounting groove 112, with the opening of the locking hole 114 facing the cover 300. Correspondingly, the cover 300 is provided with a sliding groove 310, located at the end of the cover 300 facing the locking hole 114, and extending along the arrangement direction of the cover 300 and the locking hole 114. In one example, the locking hole 114 and the cover 300 are arranged sequentially from left to right; therefore, the sliding groove 310 extends in the left-right direction. In this embodiment, a locking member 400 is provided within the sliding groove 310, and the locking member 400 is slidably connected to the sliding groove 310. Based on this, the locking member 400 can move towards or away from the locking hole 114.

[0056] Specifically, continue to refer to Figure 3 As shown in this embodiment of the invention, the locking member 400 has a fastening part 410 at one end near the latching hole 114, which can fasten with the latching hole 114. Under normal use, the cover 300 covers and seals the mounting opening 113. At this time, the fastening part 410 fastens with the latching hole 114, thereby locking the left side of the cover 300 to the outer shell 100. When disassembling or installing the filter screen 200, the user can move the locking member 400 from the left to the right along the latching groove 118, causing the fastening part 410 to disengage from the latching hole 114, thereby releasing the lock between the left side of the cover 300 and the outer shell 100, allowing the user to rotate the cover 300.

[0057] Reference Figure 4 and Figure 5 As shown, in this embodiment of the invention, a limiting protrusion 115 protrudes from the card hole 114, and the fastening part 410 is constructed as a latch 470. The latch 470 protrudes from the left side of the locking member 400, allowing it to be inserted into the card hole 114. In this embodiment, the latch 470 has a fastening groove 420 that matches the limiting protrusion 115 on the side facing the latch 115. When the locking member 400 moves from right to left, the latch 470 enters the card hole 114, and the limiting protrusion 115 moves into the fastening groove 420 and engages with it, thus locking the left side of the cover 300 to the outer shell 100. Conversely, when the locking member 400 moves from left to right along the card groove 118, the latch 470 disengages from the card hole 114, causing the limiting protrusion 115 to disengage from the fastening groove 420.

[0058] Specifically, refer to Figure 6 and Figure 7 As shown, in this embodiment of the invention, the slide groove 310 has guide grooves 320 on its two side walls in the vertical direction, combined with... Figure 8 It can be understood that the guide groove 320 can be formed by the side wall of the slide groove 310 being recessed away from the other side wall. For example, the upper side wall of the slide groove 310 is recessed upward to form one guide groove 320, and the lower side wall of the slide groove 310 is recessed downward to form another guide groove 320. In this embodiment, the extending direction of the guide groove 320 is consistent with the extending direction of the slide groove 310, both extending along the arrangement direction of the cover 300 and the locking hole 114.

[0059] refer to Figure 8 and Figure 9As shown in this embodiment of the present invention, guide portions 430 are provided on opposite sides of the locking member 400. The two guide portions 430 correspond one-to-one with the two guide grooves 320. Specifically, the guide portion 430 can be a rib protruding from the outer surface of the locking member 400. The guide portion 430 is slidably connected to the guide groove 320. Based on this, when the locking member 400 moves along the slide groove 310, the guide portion 430 moves along the guide groove 320. The sliding cooperation between the guide portion 430 and the guide groove 320 can guide the movement of the locking member 400, thereby reducing the possibility of the locking member 400 tilting during the movement and ensuring the smoothness when the user moves the locking member 400.

[0060] Reference Figure 6 and Figure 7 As shown, in this embodiment of the invention, the slide groove 310 is a semi-open groove with its opening on the left side, i.e., the side facing the locking hole 114. Based on this, the locking member 400 can be installed into the slide groove 310 from the left side of the cover 300, and can also be detached from the cover 300 from the left side. To facilitate the assembly of the locking member 400, in this embodiment, an inclined surface 330 is provided at the opening of the slide groove 310. Specifically, one end of the inclined surface 330 is connected to the left end face of the cover 300, and the other end is connected to the inner wall of the guide groove 320. When the locking member 400 enters the slide groove 310 from the left side of the cover 300, the inclined surface 330 can guide the guide portion 430, allowing the guide portion 430 to enter the guide groove 320 more smoothly, thereby reducing the installation difficulty of the locking member 400 and improving the assembly smoothness of the locking member 400.

[0061] Reference Figure 7 and Figure 8 As shown, in this embodiment of the present invention, a limiting groove 340 is formed on the inner wall of the slide groove 310. Specifically, the limiting groove 340 is formed in the inner wall of the slide groove 310 facing the locking member 400. For example, the inner wall of the slide groove 310 facing the front is recessed to form the limiting groove 340. A limiting part 440 is provided on the left side of the guide part 430. Specifically, the left end of the guide part 430 is bent towards the rear, thereby forming a limiting part 440 protruding from the guide part 430.

[0062] Understandably, since the user operates the cover 300 from the front side of the front panel 111, the force applied by the user to the locking member 400 when the user moves it along the slide groove 310 is directed towards the rear. Therefore, if the user moves the locking member 400 to the left, when the limiting part 440 reaches the front of the limiting groove 340, the limiting part 440 will fall into the limiting groove 340 under the force applied by the user, thereby stopping the locking member 400 and restricting its continued movement to the left, thus reducing the possibility of the locking member 400 dislodging due to user error.

[0063] Reference Figure 5 and Figure 8 As shown in this embodiment of the present invention, in order to facilitate the user's operation of the locking member 400, the locking member 400 at least partially protrudes from the slide groove 310. Specifically, the front end of the locking member 400 is provided with a protrusion 480 protruding from the slide groove 310, wherein an arc-shaped pressing surface 450 is provided on the side of the protrusion 480 facing the card hole 114, and a handle groove 460 is formed inside the protrusion 480, and the opening of the handle groove 460 is provided on the side of the protrusion 480 facing away from the card hole 114.

[0064] Understandably, referring to Figure 5 As shown in this embodiment of the present invention, when it is necessary to release the lock between the left end of the cover 300 and the front panel 111, the user can push the pressing surface 450 with his / her finger, thereby moving the locking member 400 to the right, and thus causing the latch 470 to disengage from the latch hole 114; conversely, when it is necessary to lock the left end of the cover 300 and the front panel 111, the user can insert his / her finger into the buckle groove 460 and use two fingers to hold the locking member 400 and move it to the left, thereby moving the latch 470 into the latch hole 114.

[0065] Reference Figure 1 and Figure 3 As shown, in this embodiment of the present invention, the front panel 111 includes two adjacent sidewalls, and the mounting groove 112 is formed on the adjacent two sidewalls of the front panel 111, with the two sidewalls forming an included angle with each other. The cover 300 is circumferentially bent around the front panel 111. Specifically, the mounting groove 112 extends to different sidewalls of the front panel 111. In this embodiment, a portion of the mounting groove 112 is located on the front sidewall of the front panel 111, and another portion is located on the right sidewall of the front panel 111. The cross-sectional shape of the mounting groove 112 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.

[0066] Reference Figure 4As shown, in this embodiment of the present invention, the mounting groove 112 includes a first groove segment 116 and a second groove segment 117. In one example, the first groove segment 116 is formed on the front sidewall of the front panel 111 and extends in the left-right direction. A locking hole 114 is formed on the left side of the first groove segment 116. The second groove segment 117 is formed on the right sidewall of the front panel 111 and extends in the front-back direction.

[0067] Among them, combined Figure 10 and Figure 11 It can be understood that the second groove segment 117 has two slots 118 on each of its two side walls along the vertical direction, and the two slots 118 are located on the rear side of the second groove segment 117. Correspondingly, refer to Figure 6 As shown in this embodiment of the invention, rotating portions 350 are provided on both sides of the cover 300. Specifically, the rotating portion 350 can be constructed as a cylindrical protrusion protruding from the cover 300. Based on this, the rotating portion 350 can engage with the slot 118 as a pivot. When the left end of the cover 300 and the front panel 111 are in an unlocked state, the cover 300 can rotate around the pivot under the action of external force.

[0068] Reference Figure 12 As shown in this embodiment of the invention, a clearance groove 119 is provided at the rear end of the second groove segment 117. To ensure sufficient rotation space when the cover 300 rotates, a portion of the inner wall of the clearance groove 119 can be an arc-shaped surface. Based on this, when the cover 300 rotates, the rear end of the cover 300 will move circumferentially along the clearance groove 119. It should be noted that the rear end of the cover 300 is the end of the cover 300 away from the locking member 400. Specifically, with Figure 12 Taking the example shown, when the left end of the cover 300 rotates towards the front, the rear end of the cover 300 will move to the left along the circumference of the clearance groove 119. The dotted line in the figure represents the movement path of the rear end of the cover 300. Conversely, when the left end of the cover 300 rotates towards the rear, the rear end of the cover 300 will move to the right along the circumference of the clearance groove 119.

[0069] Understandably, we should continue to refer to... Figure 12 As shown, to prevent interference between the cover 300 and the front panel 111 when the cover 300 rotates, in this embodiment of the invention, the minimum distance between the rear end of the cover 300 and the inner wall of the clearance groove 119 is W, which satisfies W≥0.5mm. It should be noted that the minimum distance between the rear end of the cover 300 and the inner wall of the clearance groove 119 refers to the distance between the position closest to the inner wall of the clearance groove 119 at the rear end of the cover 300 and the inner wall of the clearance groove 119. This distance is greater than or equal to 0.5mm whether the cover 300 is rotating or stationary, thus providing sufficient space for the rotation of the cover 300 and ensuring that the rotation of the cover 300 is not obstructed.

[0070] This utility model also provides a heat pump device, including the housing assembly 1000 described in the above embodiments. Specifically, the heat pump device can be a heat pump water heater or a heat pump heating system; this embodiment does not limit this.

[0071] The heat pump device of this embodiment adopts the housing assembly 1000 of the above embodiment. The heat pump device has an installation port 113 communicating with the air duct on the surface of the housing 100. A cover 300 is provided at the installation port 113. One end of the cover 300 is rotatably connected to the housing 100, and the other end is detachably connected to the housing 100. Based on this, when disassembling or installing the filter 200, it is only necessary to disconnect one end of the cover 300 from the housing 100 and rotate it away from the housing 100 to expose the installation port 113 for disassembly and installation of the filter 200. This effectively avoids the cumbersome steps of disassembling the front panel 111 required for disassembling and assembling the filter 200, simplifying the disassembly and assembly process. Furthermore, during the disassembly and assembly of the filter 200, the cover 300 remains fixed to the outer casing 100, thus preventing the cover 300 from being lost if it is completely disassembled. This achieves convenient disassembly and assembly of the filter 200, reduces the maintenance time of the heat pump equipment, lowers the difficulty of disassembling and assembling the filter 200, reduces the risk of equipment damage due to improper operation, and improves the overall structural stability of the heat pump equipment.

[0072] Since the heat pump equipment 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.

[0073] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
