[0049] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0052] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0053] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0054] Unless otherwise stated, the term "multiple" means two or more.

[0055] As can be seen from the background art, in related technologies, the casing of a heat pump outdoor unit includes several main components such as side panels, front cover, service panel, top cover, and chassis. During assembly, these components are fixedly connected by a large number of screws to ensure the stability of the casing.

[0056] Although screw connections offer high strength and reliability, the large number of screws means that a significant amount of time and effort is required during installation or disassembly, increasing both the difficulty of construction and the duration of maintenance.

[0057] Furthermore, heat pump outdoor units are typically installed on the exterior of buildings, such as rooftops, balconies, or dedicated equipment platforms. While these locations facilitate air circulation, they also expose metal connectors, such as screws, directly to the natural environment. Prolonged exposure to sunlight, rain, and temperature fluctuations can cause rust to appear on the screws, affecting their appearance and durability. Furthermore, the loosening caused by rust can compromise the stability of the casing.

[0058] In some related technologies, the heat pump outdoor unit casing does not have screws installed on the front to ensure the integrity of the front, but this will cause defects such as gaps and unevenness between the top cover and the side panel, affecting the appearance of the front of the casing.

[0059] To address the aforementioned issues, this application provides a casing structure and a heat pump outdoor unit. The casing structure includes a rear side plate, a bottom plate, a top plate, a front panel, and two covering components. The rear side plate is used to mount the evaporator. The bottom plate and top plate are both located on the rear side plate, forming the basic framework of the casing structure. The bottom of the covering component snaps into the bottom plate, and the top of the covering component snaps into the top plate. The front panel snaps into the covering component and connects to the bottom plate. This snap-fit ​​connection between components not only provides a stable connection but also facilitates disassembly and assembly, simplifying the installation process, reducing the use of screws, and minimizing aesthetic and corrosion problems caused by screws exposed to the external environment. It provides a robust, durable, and easy-to-install and maintain casing structure, contributing to improved overall aesthetics and durability of the heat pump outdoor unit.

[0060] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0061] Combination Figures 1 to 3 As shown, one embodiment of this application provides a housing structure for a heat pump outdoor unit, including a rear side plate 100 for mounting an evaporator; a bottom plate 200 and a top plate 300, both disposed on the rear side plate 100; the bottom plate 200 and the top plate 300 are arranged opposite each other in the vertical direction; two covering members 400, the bottom of the covering members 400 being snapped into the bottom plate 200 and the top of the covering members 400 being snapped into the top plate 300; in a first direction, the two covering members 400 are arranged opposite each other and cover both ends of the top plate 300 and the bottom plate 200; a front panel 500, which is snapped into the covering members 400 and is also connected to the bottom plate 200; in a second direction, the front panel 500 and the rear side plate 100 are arranged opposite each other; the first direction and the second direction are perpendicular to each other.

[0062] It should be noted that the vertical direction can be aligned with... Figure 1 The Z-axis is parallel to the first direction, which can be parallel to the second direction. Figure 1 The Y-axis is parallel to the second direction, which can be parallel to the third direction. Figure 1 The X-axis is parallel.

[0063] Understandably, the casing structure of a heat pump outdoor unit typically has a front and rear side that are positioned opposite each other, a top and bottom side that are positioned opposite each other, and a left and right side that are positioned opposite each other.

[0064] The top and bottom can be distributed in parallel along the vertical direction; the left and right sides can be distributed in parallel along the first direction; and the front and back sides can be distributed in parallel along the second direction.

[0065] The top plate 300 and the bottom plate 200 are located at the top and bottom of the shell structure; the two covering parts 400 are located on the left and right sides of the shell structure, and the front panel 500 and the rear side plate 100 are located on the front and rear sides of the shell structure.

[0066] Understandably, the rear panel 100 serves as a mounting base for the evaporator, providing a stable support structure. By securing the evaporator to the rear panel 100, the evaporator can remain stable during operation, reducing vibration and noise.

[0067] The bottom plate 200 and the top plate 300 provide a basic framework for the entire shell structure, effectively distributing and bearing external pressure and weight, and enhancing the overall strength of the shell.

[0068] The cover 400 effectively protects the left and right sides of the shell structure. Simultaneously, the cover 400 connects to the top plate 300 and bottom plate 200 via a snap-fit ​​mechanism, allowing for quick installation and removal, reducing reliance on tools and screws, and simplifying the installation and disassembly process.

[0069] The front panel 500, connected to the cover 400 and the base plate 200, provides additional support, enhancing the overall structural strength and stability of the housing. Furthermore, the snap-fit ​​connection between the front panel 500 and the cover 400 facilitates installation.

[0070] In some embodiments, the rear side panel 100, bottom panel 200, top panel 300, cover 400, and front panel 500 together form a mounting area 700 for accommodating functional elements.

[0071] The rear panel 100 is located at the rear of the mounting area 700; the front panel 500 is located at the front of the mounting area 700; the cover 400 is located at both ends of the mounting area 700 in the first direction; the top panel 300 is located at the top of the mounting area 700; and the bottom panel 200 is located at the bottom of the mounting area 700.

[0072] The front panel 500, the cover 400, the bottom plate 200, and the top plate 300 are primarily connected by snap-fit ​​joints. This snap-fit ​​connection method not only facilitates the assembly and disassembly of components but also provides better connection stability while reducing the use of screws.

[0073] For easily observable areas such as the top, bottom, front, and left and right sides of the housing structure, the number of exposed screws is reduced, thereby reducing aesthetic and corrosion problems caused by screws being exposed to the external environment.

[0074] Therefore, the housing structure of the heat pump outdoor unit provided in this application embodiment is stable, durable, and easy to install and maintain, which helps to improve the overall aesthetics and durability of the heat pump outdoor unit.

[0075] In some embodiments, the cover 400 includes a first mounting portion 410, and a second mounting portion 420 and a third mounting portion 430 connected to the first mounting portion 410; in a first direction, the first mounting portions 410 of the two cover 400s are disposed opposite to each other; the second mounting portion 420 covers the front side of the top plate 300 and the bottom plate 200; and the third mounting portion 430 covers the rear side of the top plate 300 and the bottom plate 200.

[0076] By setting the cover 400 as multiple mounting parts, it is possible to cover and support the shell structure in different directions without adding additional components.

[0077] Among them, the first mounting part 410 of the two covering parts 400 are distributed on the left and right sides of the shell structure, forming the left side plate and the right side plate of the shell structure. This can reduce the connection points between the left side plate and the right side plate and the adjacent structure, effectively reduce the use of screws, and avoid the external exposure of screws on the left and right sides of the shell structure.

[0078] Furthermore, the relative arrangement of the first mounting portions 410 of the two covering components 400 in the first direction forms a symmetrical structural layout, which helps to enhance the overall stability and symmetry of the shell structure and reduce structural deformation caused by asymmetry.

[0079] The second mounting portions 420 of the two coverings 400 cover the front sides of the top plate 300 and the bottom plate 200. That is, the second mounting portions 420 of the two coverings 400 and the front panel 500 are both located on the front side of the mounting area 700, and together they form the front wall of the mounting area 700.

[0080] Compared to traditional housing structures, the front panel 500 only covers the front side of the mounting area 700. The two ends of the front panel 500 need to be aligned and assembled with the side panels. After assembly, assembly gaps will be formed on the left and right sides of the housing structure.

[0081] Because the side panels are prone to deformation during the production process, unevenness in the front and back directions may occur after the side panels are installed, resulting in uneven assembly gaps between the side panels and the front panel 500, leading to appearance defects.

[0082] The heat pump outdoor unit housing structure provided in this application embodiment has two first mounting portions 410 of the two covering parts 400 distributed on the left and right sides of the housing structure, so that there are no assembly gaps on the left and right sides of the housing structure.

[0083] An assembly gap can be formed between the second mounting portion 420 of the cover 400 and the front panel 500. In this case, the assembly gap is concentrated on the front side of the housing structure, making it easier to hide the assembly gap (e.g., by covering it with the grille 800), which helps to improve the integration effect of the housing structure.

[0084] The third mounting portion 430 of the two covering parts 400 covers the rear side of the top plate 300 and the bottom plate 200. That is, the third mounting portion 430 of the two covering parts 400 and the rear side plate 100 are both located on the rear side of the mounting area 700, and together they form the rear wall of the mounting area 700.

[0085] With this configuration, an assembly gap can also be formed between the third mounting part 430 of the cover 400 and the rear side plate 100. These assembly gaps are concentrated on the rear side of the shell structure and are not easily observed, which also helps to improve the integration effect of the shell structure.

[0086] Combination Figure 5 As shown in some embodiments, one of the first mounting part 410 and the base plate 200 is provided with a first snap-fit ​​part 411, and the other is provided with a first slot 210, wherein the first snap-fit ​​part 411 snaps into the first slot 210.

[0087] The base plate 200 may have flanges that bend toward the installation area 700 around its perimeter.

[0088] For example, the first card slot 210 can be disposed on the base plate 200, and the first card slot 210 is disposed on the flange of the base plate 200.

[0089] The first snap-fit ​​portion 411 can be correspondingly disposed on the first mounting portion 410, and the first snap-fit ​​portion 411 can be a bent part that bends toward the receiving cavity.

[0090] During installation, the cover 400 can be placed from top to bottom for assembly with the base plate 200. After installation, the first snap-fit ​​part 411 can be inserted into the first slot 210, and the first snap-fit ​​part 411 abuts against the side of the base plate 200 facing the receiving cavity. In this way, under the snap-fit ​​action of the first snap-fit ​​part 411 and the first slot 210, the bottom end of the cover 400 can be restricted from moving relative to the base plate 200 in the first direction.

[0091] In the second direction, the width of the first slot 210 can be slightly larger than that of the first latching part 411. This facilitates the insertion of the first latching part 411 into the first slot 210 while preventing the first latching part 411 from wobbling within the first slot 210 in the second direction. Therefore, by controlling the widths of the first slot 210 and the first latching part 411 in the second direction, the movement of the bottom end of the covering member 400 relative to the base plate 200 in the second direction can be limited, improving connection stability.

[0092] Combination Figure 4 As shown, in some embodiments, one of the first mounting part 410 and the top plate 300 is provided with a second snap-fit ​​part 310, and the other is provided with a second snap-fit ​​groove 412, wherein the second snap-fit ​​part 310 snaps into the second snap-fit ​​groove 412.

[0093] In the first direction, the top plate 300 has flanges at both ends that bend toward the mounting area 700. The top of the first mounting part 410 also has a flange that bends toward the mounting area 700.

[0094] For example, the second snap-fit ​​portion 310 may be disposed on the top plate 300, and the second snap-fit ​​portion 310 is disposed on the flange of the top plate 300.

[0095] The second slot 412 can be disposed on the first connecting part, and the second slot 412 is disposed on the flange of the first connecting part.

[0096] During installation, the top plate 300 can be placed from top to bottom so that the second snap-fit ​​part 310 can be inserted into the second snap-fit ​​slot 412, thereby assembling the top plate 300 and the covering part 400. Through the snap-fit ​​action of the second snap-fit ​​part 310 and the second snap-fit ​​slot 412, the movement of the top tip of the covering part 400 relative to the top plate 300 along the first direction can be restricted.

[0097] In the second direction, the width of the second slot 412 can be slightly larger than the width of the second latching portion 310. This facilitates the insertion of the second latching portion 310 into the second slot 412 while preventing the second latching portion 310 from wobbling within the second slot 412 in the second direction. Therefore, by controlling the widths of the second slot 412 and the second latching portion 310 in the second direction, the movement of the top edge of the covering member 400 relative to the top plate 300 in the second direction can also be limited.

[0098] Combination Figure 4 As shown, in some embodiments, one of the second mounting portion 420 and the front panel 500 is provided with a third snap-fit ​​portion 501, and the other is provided with a third slot 421, wherein the third snap-fit ​​portion 501 snaps into the third slot 421.

[0099] The second mounting portion 420 may have a flange bent toward the mounting area 700 at one end opposite to the first mounting portion 410. A third slot 421 may be provided on the flange of the second mounting portion 420. The extension direction of the third slot 421 is parallel to the vertical direction.

[0100] The third latching portion 501 may be disposed on the side of the front panel 500 facing the mounting area 700, and in the first direction, at least a portion of the third latching portion 501 extends to the outside of the front panel 500.

[0101] In the vertical direction, the length of the third slot 421 is greater than the length of the third latching part 501 to reserve sufficient assembly space so that the third latching part 501 can slide in the third slot 421, which facilitates the connection between the second mounting part 420 and the front panel 500.

[0102] During installation, the third latching part 501 can be inserted into the third latching slot 421, and then the front panel 500 can be placed from top to bottom so that the third latching part 501 can slide a distance along the extension direction of the third latching slot 421 until the bottom of the front panel 500 is aligned with the base plate 200.

[0103] The bottom end of the front panel 500 can be attached to the flange on the base plate 200 on the side opposite to the mounting area 700, and the bottom end of the front panel 500 can be connected to the flange of the base plate 200 via a locking device to ensure the installation stability of the front panel 500. With this configuration, the locking devices are located on the front side of the housing structure, making them easier to conceal (e.g., by being covered by the grille 800), which improves the stability of the housing structure and also contributes to a better integrated look.

[0104] Combination Figure 2 As shown, in some embodiments, a connector 431 is provided on the third mounting part 430, and the third mounting part 430 is connected to the rear side plate 100 through the connector 431.

[0105] By using connector 431 to connect the third mounting part 430 and the rear side plate 100, the connection stability of the housing structure can be improved.

[0106] Understandably, since both the third mounting part 430 and the rear side plate 100 are located on the rear side of the housing structure, the connecting parts 431 used are also concentrated on the rear side of the housing structure, making them difficult to observe and helping to improve the integration effect of the housing structure.

[0107] For example, connector 431 may be a screw.

[0108] In some embodiments, the top plate 300 may have a flange that bends toward the mounting area 700 at one end toward the rear side plate 100, and the flange of the top plate 300 is connected to the rear side plate 100 and the third mounting part 430 via a connector 431.

[0109] In some embodiments, the flange at one end of the base plate 200 facing the rear side plate 100 can also be connected to the rear side plate 100 and the third mounting part 430 via the connector 431.

[0110] By using connector 431 to connect the top plate 300, bottom plate 200, third mounting part 430, and rear side plate 100, the connection stability of the shell structure can be further improved, ensuring the overall stability of the shell structure.

[0111] Specifically, by introducing connector 431, a high-strength and high-stability connection can be achieved in the shell structure, which helps to improve the rigidity and durability of the overall structure. Furthermore, the use of connector 431 in only a few areas, cleverly concealing the connection location at the rear, also helps maintain the aesthetics of the shell structure and reduces the risk of corrosion.

[0112] Combination Figure 1 and Figure 3 As shown, in some embodiments, a partition 600 is also included; the partition 600 is disposed within the installation area 700; the partition 600 divides the installation area 700 into a first receiving cavity 710 and a second receiving cavity 720, the first receiving cavity 710 and the second receiving cavity 720 being arranged side by side along a first direction.

[0113] Understandably, the introduction of the partition 600 provides a separation function for the interior of the housing, enabling effective organization and management of the internal space. The partition 600 can be used to isolate components with different functions, preventing mutual interference.

[0114] For example, the first receiving cavity 710 can be used to install components such as an evaporator and an air outlet structure, and the second receiving cavity 720 can be used to install components such as a compressor and an economizer.

[0115] The end of the partition plate 600 facing the rear side plate 100 can be connected to the rear side plate 100 or the third mounting part 430 through the connector 431, and the bottom of the partition plate 600 can be connected to the bottom plate 200 through the connector 431.

[0116] Combination Figure 1 and Figure 3 As shown, in some embodiments, the front panel 500 includes a front cover 510 and a service plate 520; in a first direction, a first end of the front cover 510 is engaged with a cover 400, and a second end of the front cover 510 is engaged with a partition 600, the front cover 510 being used to form the front sidewall of a first receiving cavity 710.

[0117] Understandably, designing the front panel 500 to include a front cover 510 and a service panel 520 allows for better functional zoning and maintenance convenience in the housing structure. The separate design of the front cover 510 and the service panel 520 facilitates localized maintenance and repairs without affecting the overall structure.

[0118] For example, the second end of the front cover 510 may be provided with a flange that bends toward the mounting area 700, and a slot may be provided on the flange; correspondingly, the middle partition 600 may be provided with a snap-fit ​​part, which can snap into the slot to realize the connection between the second end of the front cover 510 and the middle partition 600.

[0119] The first end of the front cover 510 may be provided with a third snap-fit ​​part 501, which snaps into the third slot 421 provided in the second mounting part 420 to realize the connection between the first end of the front cover 510 and the cover 400.

[0120] In some embodiments, the front cover 510 is provided with an air outlet 511, which can optimize the airflow inside and outside the heat pump outdoor unit to discharge exhaust gas or hot air and prevent it from accumulating inside the machine, affecting the performance and life of the heat pump.

[0121] In some embodiments, in a first direction, a first end of the repair plate 520 is engaged with a partition plate 600, and a second end of the repair plate 520 is engaged with another covering member 400. The repair plate 520 is used to form the front sidewall of the second receiving cavity 720.

[0122] The end of the partition plate 600 facing the front panel 500 may be provided with a flange that bends toward the second receiving cavity 720, and a slot may be provided on the flange; correspondingly, the side of the maintenance plate 520 facing the second receiving cavity 720 may be provided with a snap-fit ​​part, which can snap into the slot to realize the connection between the first end of the maintenance plate 520 and the partition plate 600.

[0123] The second end of the repair plate 520 may be provided with a third snap-fit ​​part 501, which snaps into the third slot 421 provided in the second mounting part 420 to realize the connection between the second end of the repair plate 520 and the cover 400.

[0124] Combination Figure 1 and Figure 6 As shown, in some embodiments, a grille 800 is also included, which is snapped onto the front panel 500 and covers the side of the front panel 500 opposite to the mounting area 700.

[0125] Understandably, the grille 800 can provide an additional protective layer for the front of the heat pump outdoor unit, preventing external objects from entering the unit through the air outlet 511, while allowing air circulation, which helps protect internal components from physical damage and environmental pollution.

[0126] In addition, the grille 800 covers the front side of the entire housing structure, which can effectively cover the assembly gap between the second mounting part 420 of the cover 400 and the front panel 500, and can also cover the connector 431 connecting the front panel 500 and the bottom plate 200, so that the front side of the housing structure has a better integrated effect.

[0127] Combination Figures 7 to 10 As shown, in some embodiments, the grille 800 includes a first grille plate 810 and a second grille plate 820. The first grille plate 810 covers the surface of the front cover 510, and the second grille plate 820 covers the surface of the service plate 520.

[0128] Since the grille 800 needs to cover the front of the entire housing structure, the grille 800 is relatively large and inconvenient to install. By making the grille 800 a split type, it is easier to assemble the grille 800 with the housing structure. Moreover, during maintenance, only the part corresponding to the maintenance area needs to be removed, instead of disassembling the whole structure, which improves the convenience of the maintenance process.

[0129] Combination Figure 8 and Figure 10 As shown, in some embodiments, the first grid plate 810 and the second grid plate 820 can be detachably connected via the fifth snap-fit ​​portion 821 and the fifth snap-fit ​​groove 811.

[0130] For example, a fifth slot 811 may be provided on the end face of the first grille plate 810 facing the second grille plate 820, and correspondingly, a fifth snap-fit ​​part 821 may be provided on the end face of the second grille plate 820 facing the first grille plate 810. When assembling the first grille plate 810 and the second grille plate 820, the fifth snap-fit ​​part 821 is inserted into the fifth slot 811.

[0131] The fifth slot 811 extends in the same direction as the vertical direction. The length of the fifth slot 811 in the extension direction is greater than the width of the fifth snap-fit ​​part 821 in the vertical direction, so as to reserve enough assembly space so that the fifth snap-fit ​​part 821 can slide in the fifth slot 811, which facilitates the installation and removal of the first grid plate 810 and the second grid plate 820.

[0132] By providing the fifth snap-fit ​​part 821 and the fifth snap-fit ​​slot 811, a quick and secure connection method is provided, allowing the two grille panels to be easily connected and disassembled. This design not only simplifies the installation process but also improves the ease of maintenance.

[0133] Combination Figure 3 and Figure 8As shown, in some embodiments, the grille 800 is provided with a fourth snap-fit ​​portion 801 on the side facing the front panel 500, and the front panel 500 is provided with a fourth snap-fit ​​groove 502, and the fourth snap-fit ​​portion 801 snaps into the fourth snap-fit ​​groove 502.

[0134] The first grille plate 810 and the second grille plate 820 are each provided with a fourth snap-fit ​​part 801. Correspondingly, the front cover 510 and the maintenance plate 520 are also provided with a fourth snap-fit ​​groove 502. The fourth snap-fit ​​part 801 and the fourth snap-fit ​​groove 502 are snap-fitted one by one.

[0135] It should be noted that the snapping direction of the fourth snap-fit ​​portion 801 on the first grid plate 810 and the snap-fit ​​direction of the fourth snap-fit ​​portion 801 on the second grid plate 820 can be perpendicular to each other, which facilitates the individual disassembly of the first grid plate 810 or the second grid plate 820.

[0136] Specifically, by employing a snap-fit ​​design with a fourth snap-fit ​​part 801 and a fourth snap-fit ​​groove 502 between the grille 800 and the front panel 500, the casing structure of the heat pump outdoor unit can be quickly assembled and securely connected without screws, which not only improves assembly efficiency but also reduces the need for tools during installation and maintenance.

[0137] In some embodiments, the surface of the grille 800 may also be provided with a locking element, and the grille 800 is also connected to the front panel 500 through the locking element to improve the connection stability between the grille 800 and the front panel 500.

[0138] Correspondingly, the surface of the grille 800 is also provided with a screw cap, which can be snapped onto the surface of the grille 800 to cover the locking parts and reduce the risk of corrosion caused by the screws being exposed to the external environment.

[0139] Another aspect of this application provides a heat pump outdoor unit, including the housing structure of the heat pump outdoor unit provided in any of the above embodiments.

[0140] The casing structure of the heat pump outdoor unit has been described in detail in the above embodiments and will not be repeated here.
