The grille is usually installed on the housing and located in front of the housing air outlet to block the air outlet and prevent foreign objects from entering the housing.

[0004] However, the grille has a large area and volume, which makes installation inconvenient. Utility Model Content

[0005] This application provides a housing assembly and a heat pump outdoor unit to solve the problem of inconvenient grille installation.

[0006] In a first aspect, embodiments of this application provide a housing assembly and a heat pump outdoor unit, including a front panel and a grille, wherein the grille is disposed on the front side of the front panel and is detachably connected to the front panel via a connector;

[0007] The connector includes a connecting part and an abutting part connected to each other. The connecting part is connected to the grille, and the abutting part is disposed at the end of the connecting part away from the grille.

[0008] There is an angle between the extending direction of the connecting portion and the extending direction of the abutting portion, so that after the connecting portion is inserted into the mounting opening of the front panel, the abutting portion is used to fix the grille to the front panel.

[0009] In one possible design, the position of the connecting portion near the end of the grille is higher than the position of the connecting portion away from the end of the grille.

[0010] In one possible design, the angle between the extending direction of the abutment and the extending direction of the connection is greater than or equal to 90° and less than or equal to 180°.

[0011] In one possible design, the extension direction of the abutment portion is parallel to the vertical direction.

[0012] In one possible design, there are multiple connectors, and the multiple abutments extend in the same direction.

[0013] In one possible design, the connector includes a guide portion, one end of the abutment portion is connected to the connector portion, the guide portion is disposed at the end of the abutment portion away from the connector portion, and extends in a direction away from the grille.

[0014] In one possible design, a limiting portion is provided on the rear side of the front panel;

[0015] The abutting portion has a protrusion on its surface facing the grille, and the protrusion abuts against the surface of the limiting portion away from the connecting portion.

[0016] In one possible design, the front panel is provided with a contact portion;

[0017] The grille is provided with multiple pressing parts, which are arranged corresponding to the connector along the height direction, and the pressing parts are interference-fitted with the contact parts.

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

[0055] As the background technology indicates, the outdoor unit of a heat pump is a key component in a cooling and heating system. Heat pump outdoor units are typically installed on the exterior of buildings to facilitate air circulation and help the heat pump effectively exchange heat.

[0056] The housing assembly is an important component of the heat pump outdoor unit, including the connected housing and grille. The grille is usually installed on the housing and located in front of the housing air outlet to block the air outlet, prevent foreign objects from entering the machine, avoid injury from the fan rotation, and improve safety.

[0057] To improve the overall aesthetics of the housing assembly, the grille is usually integrated and covers the entire front outer side of the housing, resulting in a large area and volume. Due to the large area and volume of the grille, it is usually necessary to use fixing clamps to position it and to use a large number of screws and other locking devices to install it correctly and securely to the housing, making the grille installation process complex.

[0058] The aforementioned grille is fixed to the front panel by screws and other locking devices. The screws are exposed on the surface of the housing components. On the one hand, long-term exposure to sun, rain and temperature changes will not only cause rust on the surface of the screws, affecting their appearance and durability; on the other hand, the installation or disassembly process requires a lot of time and effort, which not only increases the difficulty of construction, but also extends the maintenance cycle.

[0059] To address the aforementioned issues, this application provides a housing assembly and a heat pump outdoor unit. The housing assembly includes a front panel and a grille. The grille is disposed on the front side of the front panel and is detachably connected to the front panel via a connector. The connector includes a connecting portion and an abutting portion connected to each other. The connecting portion is connected to the grille, and the abutting portion is disposed at the end of the connecting portion away from the grille.

[0060] By setting the connector to be a connecting part and an abutting part connected together, with an angle between the extension direction of the connecting part and the extension direction of the abutting part, the abutting part can fix the grille to the front panel after the connecting part is inserted into the mounting hole of the front panel, thus realizing the installation of the grille on the front panel. This reduces the requirements for the installation process, simplifies the grille installation process, improves the installation efficiency, and reduces the complexity of installation and maintenance.

[0061] Meanwhile, the grille is connected to the front panel via connectors, which reduces the use of screws and eliminates exposed screws on the grille surface. This avoids the problem of screw corrosion and ensures the aesthetics and durability of the grille.

[0062] 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.

[0063] Combination Figures 1 to 8 As shown, one embodiment of this application provides a housing assembly, including a front panel 100 and a grille 200, with the grille 200 covering the front side of the front panel 100; the front panel 100 is provided with a mounting opening 101, and the grille 200 is provided with a connector 210, which is inserted into the mounting opening 101, and the grille 200 is detachably connected to the front panel 100 through the connector 210.

[0064] Understandably, the grille 200 covers the front side of the front panel 100, primarily to protect the air vents 102 on the front panel 100. The grille 200 prevents external objects (such as leaves, dust, or small animals) from entering the device, thus avoiding damage to internal components.

[0065] The presence of the grille 200 also helps prevent people or animals from accidentally coming into contact with the internal fan or other moving parts, reducing potential safety risks.

[0066] By setting the grille 200 to cover the entire surface of the front panel 100, it can be better integrated with the architectural appearance, enhancing the overall visual appeal of the equipment.

[0067] In some embodiments, the connector 210 includes a body 211, which may include a connecting portion 2111 and an abutting portion 2112 connected to each other. The first end of the connecting portion 2111 is connected to the grille 200 and passes through the mounting opening 101. The abutting portion 2112 is connected to the second end of the connecting portion 2111 and abuts against the side of the front panel 100 away from the grille 200, thereby connecting the grille 200 and the front panel 100.

[0068] There is an angle between the extending direction of the connecting part 2111 and the extending direction of the abutting part 2112, so that after the connecting part 2111 is inserted into the mounting opening 101 of the front panel 100, the abutting part 2112 is used to fix the grille 200 to the front panel 100.

[0069] Understandably, the connecting part 2111 and the abutting part 2112 can perform different mating functions.

[0070] The connecting part 2111 connects the grille 200 to the front panel 100 by passing through the mounting port 101; the abutting part 2112 provides support and fixation by contacting the inside of the front panel 100, which can ensure that the connecting part 210 can be firmly held in the proper position after installation, prevent the grille 200 from loosening during use, and enhance the integrity and reliability of the housing structure.

[0071] Specifically, the connecting part 2111 of the connector 210 is inserted into the mounting port 101, and can be connected to the front panel 100 through the abutment part 2112. Thus, the grille 200 can be installed by a simple insertion action, effectively reducing complex installation steps and time. At the same time, it also reduces the use of screws, so there are no exposed screws on the grille surface, thus avoiding the problem of screw corrosion and ensuring the aesthetics and durability of the grille 200.

[0072] The angle between the extending direction of the connecting part 2111 and the extending direction of the abutting part 2112 can be greater than or equal to 90° and less than or equal to 180°.

[0073] For example, the angle between the extending direction of the connecting portion 2111 and the extending direction of the abutting portion 2112 is 90°.

[0074] The extension direction of the connecting part 2111 can be perpendicular or approximately perpendicular to the plane where the grille 200 is located, so that the connecting part 2111 can be more easily inserted into the mounting port 101. The extension direction of the connecting part 2111 is perpendicular to the extension direction of the abutting part 2112, so as to provide a structure that can be parallel to the plane where the front panel 100 is located, so as to facilitate the connection with the front panel 100.

[0075] In the housing assembly provided in this application embodiment, the front panel 100 may be provided with multiple mounting ports 101; correspondingly, the grille 200 may be provided with multiple connectors 210, which are inserted into the mounting ports 101 and connected to the front panel 100.

[0076] The connection of multiple mounting ports 101 and connectors 210 helps ensure that the grille 200 can be securely fixed to the front panel 100, thereby maintaining stability during equipment operation.

[0077] Specifically, the multiple abutment portions 2112 of the multiple connectors 210 extend in the same direction. Among them, the extension direction of the abutment portion 2112 is parallel to the vertical direction, and the abutment portion 2112 can extend downward.

[0078] If the extension direction of the abutment portion 2112 is parallel to the vertical direction, then the extension direction of the abutment portion 2112 can be parallel to the plane on which the front panel 100 is located, which facilitates the abutment of the abutment portion 2112 with the front panel 100.

[0079] During the installation of the grille 200, after aligning the grille 200 with the front panel 100 and inserting the connecting part 2111 into the mounting port 101, simply move the grille 200 downwards to allow the abutting parts 2112 of multiple connecting parts 210 to move downwards simultaneously to reach the bottom of the mounting port 101 and abut against the front panel 100, making the operation convenient.

[0080] In some embodiments, the connector 210 includes a guide portion 212 disposed at one end of the abutment portion 2112 away from the connector portion 2111, the guide portion 212 extending in a direction away from the grille 200.

[0081] During the process of inserting the connector 210 into the mounting port 101, the guide part 212 is inserted into the mounting port 101 before the main body 211, which makes it easy for the connector 210 to correspond one-to-one with the mounting port 101, helps the connector 210 to automatically align during the insertion process, and ensures the accuracy of the installation.

[0082] The guide portion 212 can slide in contact with the inner wall of the mounting port 101, thus guiding the connector 210 when it is inserted into the mounting port 101, ensuring that the connector 210 can smoothly enter the mounting port 101. This reduces the difficulty of alignment during installation. This design helps to reduce installation errors caused by human factors and improves the installation quality of the grille 200 on the front panel 100.

[0083] Specifically, the housing assembly provided in this application, due to the guiding function of the guide portion 212 and the quick-insertion design of the connector 210, simplifies the installation steps of the grille 200, making the installation process of the grille 200 more efficient and reducing installation time and labor costs. Furthermore, the disassembly and reinstallation of the grille 200 are also simpler, reducing maintenance complexity and costs.

[0084] Combination Figure 2 and Figure 5 As shown, in some embodiments, the connector 210 is disposed on the side of the grille 200 facing the front panel 100; at least a portion of the guide portion 212 is away from the grille 200 relative to the body 211.

[0085] The connector 210 is located on the side of the grille 200 facing the front panel 100. This proximity facilitates connection to the front panel 100, and ensures that it remains concealed after installation, maintaining the clean and aesthetically pleasing appearance of the grille 200. Furthermore, the connector 210's location on the inner side of the grille 200 reduces the impact of external environmental factors such as rain and dust, thereby improving its durability and lifespan.

[0086] At least a portion of the guide portion 212 extends away from the grille 200 relative to the body 211, which ensures that the guide portion 212 can enter the mounting port 101 first when the connector 210 is inserted into the mounting port 101, providing better guidance and alignment.

[0087] Because the guide portion 212 enters the mounting opening 101 before the main body 211, it reduces the friction between the main body 211 and the inner wall of the mounting opening 101, thereby reducing installation resistance and making the installation process smoother. Furthermore, the guide portion 212 also helps the connector 210 align itself with the mounting opening 101 during insertion, ensuring that the connector 210 is accurately positioned within the mounting opening 101, thus improving installation accuracy.

[0088] For example, the guide portion 212, the connecting portion 2111 and the abutting portion 2112 can be integrally formed and disposed on the inner surface of the grille 200, so as to ensure the strength of the connector 210 and thereby improve the installation stability of the grille 200 and the front panel 100.

[0089] By connecting the guide portion 212 to the distal end of the abutment portion 2112, the stability and accuracy of the guide portion 212 when guiding the connector 210 into the mounting port 101 are ensured. This connection method allows the guide portion 212 to function better during the guiding process, improving the efficiency and success rate of installation.

[0090] Combination Figure 4 As shown, in some embodiments, the guide portion 212 is provided with a first guide surface 2121, which is connected to the surface of the main body 211 away from the grille 200, and the end of the first guide surface 2121 away from the main body 211 is inclined downward.

[0091] The first guide surface 2121 provides a smooth transition surface for the insertion of the connector 210, reducing the direct friction between the connector 210 and the inner wall of the mounting port 101, thereby reducing the resistance during the insertion process, making the installation smoother, and enhancing the guiding function of the guide part 212.

[0092] The distal end of the first guide surface 2121 is set to be inclined downward, so that the guide surface can more easily enter the mounting port 101 at the beginning of insertion, which helps the connector 210 to automatically align during the insertion process, reduces the difficulty of manually aligning the connector 210 with the mounting port 101, reduces possible jamming or misalignment during insertion, optimizes the guiding process, and improves the success rate of installation.

[0093] Specifically, by providing an inclined first guide surface 2121 on the guide portion 212, the guide portion 212 can more easily enter the mounting port 101, thereby making it easier for installers to insert the connector 210 into the mounting port 101, reducing the difficulty of alignment and insertion, and helping to make the entire installation process smoother and more efficient.

[0094] In some embodiments, the position of the connecting portion 2111 near the end of the grille 200 is higher than the position of the connecting portion 2111 away from the grille 200.

[0095] Understandably, the end of the connecting part 2111 away from the grille 200 and the end of the connecting part 2111 near the grille 200 are inclined upwards.

[0096] The upward-sloping connecting part 2111 can more easily enter the mounting port 101 at the beginning of insertion, reducing possible jamming or misalignment during insertion and improving the success rate of installation.

[0097] In some embodiments, the connecting portion 2111 may be provided with a second guide surface 21111, which is connected to the surface of the abutting portion 2112 away from the grille 200; the second guide surface 21111 is inclined upward in the direction close to the grille 200.

[0098] The presence of the second guide surface 21111 provides additional guidance for the insertion of the connector 210, further ensuring that the connector 210 can enter the mounting port 101.

[0099] The second guide surface 21111 is designed to be inclined upward in the direction close to the grille 200, which makes it easier for the second guide surface 21111 to enter the mounting port 101 at the beginning of insertion, reducing possible jamming or misalignment during insertion and improving the success rate of installation.

[0100] Understandably, the second guide surface 21111 is an inclined surface provided on the surface of the connecting portion 2111. That is, the cross-sectional area of ​​the end of the connecting portion 2111 near the grille 200 is larger than the cross-sectional area of ​​the end of the connecting portion 2111 away from the grille 200. This arrangement can ensure the connection strength between the connecting portion 2111 and the grille 200, making the connecting portion 2111 less prone to breakage and failure. After the grille 200 is connected to the front panel 100, the grille 200 can be stably maintained on the surface of the front panel 100.

[0101] Combination Figures 6 to 8 As shown, in some embodiments, a limiting portion 110 is provided on the rear side of the front panel 100; a protrusion 21121 is provided on the surface of the abutting portion 2112 facing the grille 200, and the protrusion 21121 abuts against the surface of the limiting portion 110 away from the connecting portion 2111.

[0102] For example, the limiting portion 110 may be an arc-shaped profile provided on the front panel 100, protruding from the side of the front panel 100 opposite to the grille 200. The contact between the protrusion 21121 and the limiting portion 110 provides an additional fixing effect, ensuring that the connector 210 can be accurately positioned within the mounting opening 101 after installation, and ensuring that the grille 200 can maintain its position when subjected to external force.

[0103] Combination Figure 6 As shown, in a specific implementation, the guide part 212 is first inserted into the mounting port 101, and then the abutting part 2112 can be aligned with the position of the mounting port 101 and pass through the mounting port 101 so that the connecting part 2111 can be inserted into the mounting port 101.

[0104] Combination Figure 7 As shown, after the abutting part 2112 passes through the mounting opening 101, by moving the grille 200 downward, the abutting part 2112 can move downward relative to the mounting opening 101, so that the abutting part 2112 can deviate from the mounting opening 101, and the protrusion 21121 of the abutting part 2112 can contact the surface of the limiting part 110 near the connecting part 2111.

[0105] Combination Figure 8 As shown, the grille 200 continues to move downwards, causing the protrusion 21121 of the abutment portion 2112 to continue moving relative to the mounting opening 101. Under the action of the limiting portion 110, the abutment portion 2112 elastically deforms away from the grille 200. When the protrusion 21121 passes the position of the limiting portion 110, the abutment portion 2112 returns to its original shape, and the protrusion 21121 can abut against the surface of the limiting portion 110 away from the connecting portion 2111. At this time, the lower surface of the connecting portion 2111 can abut against the inner wall of the mounting opening 101, and the grille 200 will not move further downwards; at the same time, under the abutment action of the protrusion 21121 and the limiting portion 110, the grille 200 will not move upwards, thus achieving stable installation of the grille 200.

[0106] The bottom of the guide portion 212 and the abutment portion 2112 is provided with an inclined surface parallel to the first guide surface 2121. When the protrusion 21121 cooperates with the limiting portion 110, the inclined surface can slide and contact the surface of the limiting portion 110, so that the protrusion 21121 can smoothly pass through the location of the limiting portion 110 and reach the bottom of the limiting portion 110 to abut and connect with the limiting portion 110.

[0107] In some embodiments, the front panel 100 is provided with a contact portion 120; the grille 200 is provided with a plurality of pressing portions 220, the pressing portions 220 and the connector 210 are correspondingly provided in the height direction, and the pressing portions 220 and the contact portions 120 are interference fit.

[0108] Understandably, since the grille 200 needs to cover the entire front panel 100, the overall volume of the grille 200 is relatively large. The grille 200 is provided with a connector 210, which can support the grille 200 and the front panel 100, making the surface of the grille 200 flat.

[0109] Since the housing components are usually located outdoors, under the influence of the external environment, the areas on the grille 200 without connectors 210 may experience concave deformation due to insufficient support.

[0110] By providing a contact portion 120 on the front panel 100 and designing multiple pressing portions 220 on the grille 200, and using an interference fit, the pressing portions 220 can tightly abut against the contact portion 120, thereby providing effective support for the grille 200, ensuring uniform force on the grille 200, reducing deformation or damage caused by uneven local force, ensuring the flatness of the grille 200 on the front panel 100, and reducing the problem of gaps between the grille 200 and the front panel 100 caused by deformation of the grille 200.

[0111] The clamping part 220 and the connecting part 210 are arranged correspondingly along the height direction to ensure the stability of the grille 200 in the entire height direction and prevent the grille 200 from tilting or loosening.

[0112] In some embodiments, the contact portion 120 is inclined, and in the vertical direction, the top end of the contact portion 120 is close to the grille 200 relative to the bottom end of the contact portion 120; during the process of inserting the connector 210 into the mounting port 101, the clamping portion 220 moves from the top end of the contact portion 120 toward the bottom end of the contact portion 120.

[0113] For example, the contact portion 120 may be a pressed form disposed on the front panel 100, and the pressed form protrudes away from the grille 200. The side of the pressed form away from the grille 200 is an inclined surface, and the distance from the top of the inclined surface to the grille 200 is greater than the distance from the bottom of the inclined surface to the grille 200.

[0114] Understandably, the angled contact portion 120 helps guide the clamping portion 220 to move more smoothly during installation, reducing resistance during installation. Furthermore, the angled design provides better fixation after installation, as the clamping portion 220 is naturally guided to a more stable position.

[0115] During the insertion of the connector 210, the clamping part 220 moves from the top end to the bottom end of the contact part 120. The clamping part 220 is gradually subjected to greater pressure during the installation process to achieve a tight contact with the contact part 120, thereby providing effective support for the grille 200.

[0116] Furthermore, when the protrusion 21121 abuts against the surface of the limiting part 110 away from the connecting part 2111, the pressing part 220 can also move out of the range of the contact part 120 from the bottom end of the contact part 120 to abut against the front panel 100. This makes the abutment between the pressing part 220 and the front panel 100 tighter, thereby providing greater support for the grille 200.

[0117] For example, the clamping part 220 is a U-shaped part, with both ends of the clamping part 220 disposed on the grille 200. The first end of the clamping part 220 is disposed close to the connector 210, and the second end is located below the first end. This arrangement facilitates sliding contact between the clamping part 220 and the bottom surface of the contact part 120, reduces frictional resistance, and improves the smoothness of the movement of the clamping part 220 from the top end to the bottom end of the contact part 120 during assembly.

[0118] Combination Figure 3 and Figure 5 As shown, in some embodiments, the edges of the grille 200 are provided with a mating portion 230 extending to the front panel 100. The mating portion 230 is aligned with the edge of the front panel 100, which can optimize the fit between the grille 200 and the front panel 100, and achieve the optimization of the grille 200 seam and the aesthetic appearance of the housing assembly while ensuring functionality.

[0119] Another aspect of this application provides a heat pump outdoor unit, including a compressor, a heat exchanger, and a housing assembly provided in any of the above embodiments; the compressor and the heat exchanger are both disposed within the housing assembly, and the compressor and the heat exchanger are connected by pipes.

[0120] The housing assembly has been described in detail in the above embodiments and will not be repeated here.

[0121] For example, the outdoor unit of a heat pump can be the outdoor unit of an air conditioner, water heater, or heater.

[0122] The heat pump outdoor unit also has a partition plate inside the casing assembly. The partition plate can divide the installation space inside the casing assembly into two installation areas, which can be distributed along the left and right sides of the casing.

[0123] For example, the installation area on the right can be used to install components such as compressors. The compressor can compress low-temperature, low-pressure refrigerant into high-temperature, high-pressure gas, and it can also provide power for refrigerant circulation, enabling the refrigerant to flow continuously in the system and achieve heat transfer.

[0124] The installation area on the left can be used to install components such as heat exchangers and fans. The fan is located on the side of the heat exchange device closer to the front panel 100. When the fan is running, it draws air from the rear of the housing assembly. The drawn-in air flows through the heat exchanger and exchanges heat with it. The front panel 100 is provided with an air outlet 102 at the position corresponding to this installation area. After the heat exchange, the air passes through the fan and finally flows out of the housing assembly from the air outlet 102.

[0125] In summary, the heat pump outdoor unit provided in this application embodiment, by configuring the connector 210 as a connecting part 2111 and an abutting part 2112 connected together, with an angle between the extending direction of the connecting part 2111 and the extending direction of the abutting part 2112, can fix the grille 200 on the front panel 100 after the connecting part 2111 is inserted into the mounting opening of the front panel 100, thereby realizing the installation of the grille 200 on the front panel 100, reducing the requirements for the installation process and simplifying the grille installation process.

[0126] Furthermore, a guide portion 212 is provided on the connector 210. During the insertion of the connector 210 into the mounting port 101, the guide portion 212 can be inserted into the mounting port 101 before the connector 2111, and the guide portion 212 can slide in contact with the inner wall of the mounting port 101. The guide portion 212 helps guide the connector 210 during installation, making it easier for the connector 210 to be inserted into the mounting port 101, improving the efficiency and accuracy of installation, and reducing the complexity of installation and maintenance.
