Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, and in particular relates to an indoor unit of an air conditioner. Background Technology

[0002] A typical console air conditioner indoor unit includes a casing, an indoor heat exchanger, a centrifugal fan, and refrigerant piping connecting the indoor unit. The casing, formed by a cover and base, defines the internal space, and the indoor heat exchanger and centrifugal fan are housed within the casing. The low-pressure and high-pressure pipes of the indoor unit are connected to the outdoor unit via connecting pipes. To prevent the piping from shaking and colliding with surrounding objects, which could cause damage, the console air conditioner indoor unit requires fasteners to secure the piping. These fasteners are installed on the base and clamp the piping, effectively reducing shaking and protecting the piping.

[0003] In the existing technology, there are two main installation methods for the pipe fixing components and base of the console air conditioner indoor unit: one is the screw fixing method, where the fixing component is usually a U-shaped structure. After clamping the pipe, it is connected to the base by screws. During installation, the through hole on the fixing component needs to be aligned with the through hole on the base, and then the screw is tightened. The other is the hook fixing method, where the fixing component has two opposing clamping arms. The free end of the clamping arm is provided with a hook. During installation, the fixing component needs to be squeezed by hand to compress it. After inserting it into the slot of the base, it is released. The rebound force makes the hook and the slot of the base form a snap-fit ​​fixation.

[0004] Both of the above-mentioned fixing methods have technical defects. While screw fixing offers high reliability, it requires precise hole alignment and tool operation, making installation and disassembly cumbersome and inefficient. Furthermore, after-sales maintenance necessitates screw removal, hindering ease of repair. Although hook fixing requires no tools, continuous hand compression during installation is laborious. As disclosed in announcement number CN214199089U, the fasteners, indoor units, and air conditioners are prone to detaching from the base's slots under downward impact (such as during transportation or drops), losing their fixing function and exhibiting poor reliability. Moreover, the hook structure is under constant high stress, making it susceptible to creep relaxation, causing the locking force to weaken over time and failing to maintain a stable anti-detachment effect over the long term. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, This utility model provides an indoor unit for an air conditioner, which includes: Housing, the housing comprising: The cover has a first air outlet at its top, and an air inlet and a second air outlet on the front panel of the cover. In the height direction of the housing, the air inlet is located above the second air outlet. A base, connected to the cover, defines a first cavity and a second cavity arranged along a first direction. The base has a first side plate and a rear panel for surrounding the second cavity. The rear panel is disposed opposite to the front panel. The first direction is perpendicular to the height direction. An indoor heat exchanger is located in the first cavity; A centrifugal fan is disposed in the first cavity and located on the leeward side of the indoor heat exchanger; A support portion is formed on the rear panel and located in the second cavity, and the support portion is provided with two snap-fit ​​portions; Fasteners, used to secure pipelines, include: Two clamping arms are arranged opposite each other, the clamping arms extend along a second direction, the first ends of the two clamping arms are connected, and together they define a clamping space for accommodating the pipeline. The second direction is perpendicular to the first direction and the height direction. The hooks are provided at the second end of the clamping arm and are located on the side of the clamping arm opposite to the first side plate. The two hooks are adapted to be connected to the two snap-fit ​​parts. An elastic cantilever is provided on the side of the first clamping arm near the first side plate. The elastic cantilever is inclinedly provided at the second end of the first clamping arm and its free end extends toward the front panel. The clamping arm near the first side plate is defined as the first clamping arm, and the hook on the first clamping arm is defined as the first hook. When the fastener is snapped onto the support, the free end abuts against the first side plate. Under the pressure of the first side plate, the elastic cantilever applies a clamping force to the first hook to bring it closer to the other hook, so that the two hooks and the corresponding snap-fit ​​parts form an anti-detachment structure.

[0006] The above technical solution has the following advantages or beneficial effects: When the fastener is snapped onto the support, the compression of the elastic cantilever by the first side plate ensures that the two hooks remain tightly against the engagement parts, forming a stable anti-detachment structure and continuously maintaining a locked state. This prevents the hooks from falling off due to random movement of the fastener during transportation or drops, especially when subjected to impacts away from the front panel, thus improving the reliability of the fastener. Simultaneously, when the fastener is installed onto the support, the two hooks are aligned with the two engagement parts. There is no need to pinch or compress the fastener by hand; simply pressing downwards allows for rapid installation, improving installation efficiency.

[0007] According to embodiments of this disclosure, the two snap-fit ​​portions are as follows: The first snap-fit ​​portion is provided on the support side wall of the support portion facing the first side plate, and the first snap-fit ​​portion is adapted to be connected to the first snap hook. The second snap-fit ​​portion is provided on the top support wall of the support portion facing the front panel and is adapted to be connected with another snap hook. The first side plate is set perpendicular to the front panel.

[0008] The above technical solution has the following advantages or beneficial effects: by setting snap-fit ​​parts on the top wall and side wall of the support respectively, the fasteners can be fixed at multiple points, which restricts the fasteners in multiple directions and enhances the overall stability and anti-shaking ability.

[0009] According to an embodiment of this disclosure, the first hook includes: A limiting part is provided extending along the length direction of the first clamping arm, and the limiting part is spaced apart from the first clamping arm to limit the displacement of the first hook in the direction perpendicular to the support sidewall. The first abutting part is connected between the first clamping arm and the end of the limiting part away from the front panel. The first abutting part is inserted into the first locking part and abuts against the side wall of the first locking part near the front panel, so that the first clamping arm is locked and fixed to the support part.

[0010] The above technical solution has the following advantages or beneficial effects: When the elastic cantilever is in a compressed state, the first hook is restricted from displacement in the direction perpendicular to the support side wall and in the direction perpendicular to the front panel by the cooperation of the limiting part and the first abutting part, thereby achieving limiting in four directions, ensuring that the first hook will not accidentally come out after being engaged, and enhancing the firmness of the engagement.

[0011] According to an embodiment of the present disclosure, a disassembly structure is provided on the side of the first clamping arm near the first side plate, and the disassembly structure is spaced apart from the elastic cantilever in the extending direction of the first clamping arm. Specifically, applying a pressing force away from the first side plate to the disassembly structure causes the first hook to disengage from the corresponding snap-fit ​​portion.

[0012] The above technical solution has the following advantages or beneficial effects: by setting the disassembly structure and the first hook at an interval, when the disassembly structure is pressed, the first hook can be disengaged from the corresponding locking part by lever action and elastic deformation of the first clamping arm, realizing convenient disassembly without tools and improving disassembly efficiency.

[0013] According to an embodiment of this disclosure, the disassembly structure includes a pressing cantilever extending along the length of the first clamping arm. One end of the pressing cantilever away from the front panel is connected to the first clamping arm, and the free end of the pressing cantilever is spaced apart from the first clamping arm.

[0014] The above technical solution has the following advantages or beneficial effects: the design of the pressing cantilever provides an intuitive and effortless operation method, and the user only needs to press the free end to trigger the disassembly mechanism. When pressed, the pressing cantilever deforms, causing the first hook to move away from the other hook, so as to disengage from the locking part, reducing the difficulty of operation for the user.

[0015] According to an embodiment of this disclosure, a cable routing groove is formed between the pressing cantilever and the first clamping arm, and a stop portion is provided at the free end of the pressing cantilever to restrict the cable from coming out of the cable routing groove.

[0016] The above technical solution has the following advantages or beneficial effects: the pressing cantilever and the first clamping arm naturally form a wiring space, and the stop part plays a limiting role at the free end, thereby expanding the function of the fixing component, solving the problem of inconvenient wiring and management of internal cables in the air conditioner indoor unit, and improving the overall integrity and safety of the product.

[0017] According to an embodiment of this disclosure, at least one end of the hook remote from the front panel is provided with a guide surface.

[0018] The above technical solution has the following advantages or beneficial effects: the guide surface is set at the end of the hook, which can guide the hook to smoothly enter the locking part, reduce installation resistance, and allow direct pressing operation during the installation of the fastener, thereby improving installation efficiency, solving the problem of difficulty in aligning the hook and the locking part during installation, and simplifying the production and assembly process.

[0019] According to an embodiment of this disclosure, the dimension L1 of the fastener in the extending direction of the clamping arm and the extension length L2 of the disassembly structure satisfy: L1≥50mm, L2≥25mm; wherein, the height of the free end of the disassembly structure does not exceed the height of the end of the fastener near the front panel.

[0020] The above technical solution has the following advantages or beneficial effects: If L1 < 50mm and L2 < 25mm, the pressing force on the disassembly structure during fastener removal is too large, increasing the difficulty of operation. Furthermore, if L2 is too small, not only is the contact area between the production line personnel's fingers and the fastener small, making operation difficult, but the resulting deformation is also small, insufficient to completely disengage the first hook from its corresponding locking part. By setting L1 ≥ 50mm and L2 ≥ 25mm, it is effectively ensured that when force is applied to the upper disassembly structure, the lower first hook disengages from its corresponding locking part, achieving easy disassembly and reducing the difficulty of operation.

[0021] According to embodiments of this disclosure, the clamping arm furthest from the first side plate is defined as the second clamping arm, and the hook on the second clamping arm is defined as the second hook, the second hook comprising: An insertion part is provided at the second end of the second clamping arm, and the insertion part is inserted into the corresponding snap-fit ​​part; The second abutting part is connected to the insertion part and extends in a direction away from the second clamping arm. The second abutting part abuts against the side wall of its corresponding snap-fit ​​part so that the second clamping arm is snapped and fixed to the support part.

[0022] The above technical solution has the following advantages or beneficial effects: the insertion part is easy to insert into the snap-fit ​​part, the second abutting part is limited and abutted against the side wall of the snap-fit ​​part to form a mechanical lock, and the insertion part and the second abutting part ensure that the second hook is reliably snapped into the snap-fit ​​part, so that the first clamping arm will not accidentally come out.

[0023] According to embodiments of this disclosure, an air conditioning indoor unit is also provided, comprising: A housing, the housing including a base, the base having a first side plate; A support portion is formed on the base, and the support portion is spaced apart from the first side plate; Two snap-fit ​​parts are spaced apart on the support part; Fasteners, used to secure pipelines, include: The second clamping arm has a second hook protruding from the direction away from the first side plate at its second end. The second hook is adapted to be connected to a locking part away from the first side plate. A first clamping arm is disposed opposite to a second clamping arm, and a first end of the second clamping arm is connected to a first end of the first clamping arm to form a clamping space near the connection point to accommodate the pipeline. An elastic hook structure is provided at the second end of the first clamping arm. The elastic hook structure has a first hook protruding in a direction away from the first side plate. The first hook is adapted to be connected to another of the hook-fitting parts. When the fastener is snapped onto the support, the first side plate exerts a compressive force on the elastic hook structure. Under the action of the compressive force, the first hook tends to move toward the second hook, so that the second hook, the first hook, and the corresponding snap-fit ​​part form an anti-detachment structure.

[0024] The above technical solution has the following advantages or beneficial effects: the squeezing force of the first side plate on the elastic hook structure makes the first hook tend to move towards the second hook, forming an anti-detachment structure, preventing the hook from falling off due to the random movement of the fastener during transportation and drop, especially when subjected to impact in the direction away from the front panel, thus improving the reliability of the fastening.

[0032] The air conditioner indoor unit 100 provided in this embodiment of the utility model can have various implementation forms. Among them, the air conditioner indoor unit 100 is a console air conditioner, which can be installed in a floor-standing position (including floor-standing installation) or wall-mounted installation. See below for reference. Figures 1-12 The indoor unit 100 of the air conditioner is described.

[0033] It should be noted that the indoor unit 100 is part of the air conditioner. The indoor unit 100 is installed indoors and used for heat exchange with the indoor environment. In addition, the air conditioner also includes an outdoor unit, which is usually installed outdoors and used to carry heat from the indoor environment to the outside.

[0034] refer to Figures 1-3 In one illustrative embodiment of the air conditioner indoor unit 100 provided by this utility model, the air conditioner indoor unit 100 may include a housing 10. The housing 10 is installed indoors, and the housing 10 forms the overall appearance of the air conditioner indoor unit 100.

[0035] The casing 10 is roughly cubic or cuboid in shape, see reference. Figure 5 The left and right ends of the housing 10 are the two ends of the housing 10 that are arranged opposite to each other in the first direction.

[0036] The housing 10 has an internal receiving space. This receiving space is used to house and fix various components in the indoor unit 100 of the air conditioner, which can prevent external objects from colliding with the various components inside the housing 10, thereby improving the reliability of the indoor unit 100 during transportation or installation.

[0037] In some embodiments of this application, the housing may include a base 17, which is adapted to sit on the ground, a window, or be mounted on a wall.

[0038] The housing may include a cover 16, which is connected to a base 17. The base 17 and the cover 16 are connected to define a first cavity 14 and a second cavity 15 arranged along a first direction.

[0039] The housing 16 may include a front panel 161, which forms the front side of the casing. (Reference) Figure 1 , Figure 2 An air inlet 11 is provided on the front panel 161.

[0040] The air inlet 11 is connected to the first cavity 14. The air inlet 11 serves as the inlet for external air to flow into the casing 10, allowing indoor air to enter the first cavity 14 through the air inlet 11.

[0041] It should be noted that the directions described in the text are based on the direction in which the user faces the indoor unit 100 of the air conditioner. Specifically, the side of the indoor unit 100 facing the user when in use is defined as the front side, and the opposite side is defined as the rear side. The left and right sides are distinguished by the direction in which the user faces the indoor unit 100 of the air conditioner.

[0042] In some embodiments of this application, reference is made to Figure 1 The housing 10 may include a first air outlet 12, which is located on the top of the cover 16.

[0043] The first air outlet 12 is connected to the first cavity 14. The first air outlet 12 serves as the outlet for the airflow in the first cavity 14, allowing the airflow in the first cavity 14 to flow out through the first air outlet 12.

[0044] The housing 10 may include a second air outlet 13, which is located on the front panel 161.

[0045] The second air outlet 13 can be connected to the first cavity 14. The second air outlet 13 can serve as a co-exit for the airflow in the first cavity 14, allowing the airflow in the first cavity 14 to flow out through the second air outlet 13. The connection between the second air outlet 13 and the first cavity 14 can be controlled by the damper 19.

[0046] refer to Figure 1 In the height direction of the housing 10, the air inlet 11 is located above the second air outlet 13. The height direction of the housing 10 is perpendicular to the first direction.

[0047] In some embodiments of this application, reference is made to Figure 3 The indoor unit 100 of the air conditioner may include an indoor heat exchanger 20. The indoor heat exchanger 20 is disposed in the first cavity 14 and is used to exchange heat with the airflow in the first cavity 14 through the air inlet 11.

[0048] In some embodiments of this application, the indoor unit 100 of the air conditioner may include a centrifugal fan.

[0049] A centrifugal fan is installed in the first chamber 14, located on the leeward side of the indoor heat exchanger 20. The centrifugal fan is used to drive indoor air outside the casing 10 into the first chamber 14 through the air inlet 11, and drive the airflow in the first chamber 14 to flow along the air inlet 11 toward the first air outlet 12 and the second air outlet 13.

[0050] When the indoor unit 100 of the air conditioner is running, the indoor air enters the containment space through the air inlet 11 under the rotation of the centrifugal fan. The indoor air in the containment space flows through the indoor heat exchanger 20 for heat exchange. The heat exchanged airflow is discharged to the outside of the room through the air outlet 2, thereby enabling the air conditioner to cool and heat, play a role in regulating the indoor temperature, and achieve the user's comfortable temperature.

[0051] In some embodiments of this application, reference is made to Figure 1 The indoor unit of the air conditioner 100 may include an air inlet grille 18.

[0052] An air intake grille 18 is located at the air intake 11 to filter the air and prevent larger impurities from entering the first chamber 14.

[0053] An air conditioner outdoor unit may include an outdoor unit casing, which forms the appearance of the air conditioner outdoor unit.

[0054] An outdoor unit of an air conditioner may include an outdoor heat exchanger, which may be located in the outdoor unit casing.

[0055] An air conditioner may include a compressor, which may be located inside the outdoor unit casing.

[0056] Air conditioners may include a throttling device. The throttling device is used to limit airflow. The throttling device may be provided in the indoor unit 100 or the outdoor unit of the air conditioner.

[0057] Air conditioners execute a refrigeration cycle using a compressor, condenser, throttling device, and evaporator. The refrigeration cycle involves a series of processes including compression, condensation, expansion, and evaporation, supplying refrigerant to the conditioned and heat-exchanged air.

[0058] The compressor compresses the refrigerant gas at low temperature and low pressure and discharges it at high temperature and high pressure. The discharged refrigerant gas flows into the condenser.

[0059] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released into the surrounding environment through the condensation process.

[0060] The throttling device causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand into a low-pressure liquid refrigerant.

[0061] The evaporator evaporates the refrigerant that expands in the throttling device and returns the refrigerant gas, which is in a low-temperature and low-pressure state, to the compressor.

[0062] An evaporator achieves a cooling effect by exchanging heat with the material being cooled using the latent heat of refrigerant evaporation. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0063] Of the indoor heat exchanger 20 and the outdoor heat exchanger, one is a condenser and the other is the indoor heat exchanger 20. When the indoor heat exchanger 20 is used as a condenser, the air conditioner is used as a heater in heating mode. When the indoor heat exchanger 20 is used as an evaporator, the air conditioner is used as a cooler in cooling mode.

[0064] In this embodiment, the indoor heat exchanger 20 is arranged vertically, and the axial direction of the centrifugal fan is perpendicular to the surface of the indoor heat exchanger 20, so that the airflow passes horizontally through the indoor heat exchanger 20 along the air inlet 11, effectively reducing the thickness of the unit and realizing the ultra-thin design of the air conditioning indoor unit.

[0065] The first air outlet 12 and the second air outlet 13 can be elongated and can extend along the first direction of the casing 10, improving the aesthetics of the indoor air conditioning unit 100. In this embodiment, when the indoor air conditioning unit 100 is working, it draws in air from the front and discharges air towards the top and bottom front side, which is convenient for installation.

[0066] In some embodiments of this application, the base 17 may include a first side plate 172 for forming a second cavity 15. In this embodiment, the first side plate 172 may form one end of the base 17 in a first direction. Of course, in other embodiments, the first side plate 172 may form one end of the base 17 in the height direction of the housing.

[0067] The low-pressure pipe and high-pressure pipe of the indoor unit of an air conditioner are usually connected to the outdoor unit of the air conditioner through connecting pipes. During the assembly process, the low-pressure pipe of the indoor unit of the air conditioner needs to be fixed to reduce vibration and prevent the low-pressure pipe from shaking and colliding with surrounding objects, which could cause damage to the pipe.

[0068] In related technologies, the low-pressure pipes and other pipelines of the indoor unit of an air conditioner are mostly fixed by fasteners such as clamps 30. The installation methods of the fasteners 30 and the base 17 are mainly: 1. fixing with screws; 2. fixing with barbs. The screw fixing method improves the fixing reliability, but it requires the worker to align the through hole and the through hole before fixing with screws. When fixing with barbs, the fastener 30 has two clamping arms with the free ends of the two clamping arms flared outwards. During installation, the fastener needs to be squeezed by hand to compress it, and after releasing it, the barb structure forms a fixation. This fixing method will detach from the base 17 when subjected to downward (installation direction) impact.

[0069] To improve the stability of the piping layout and the reliability of the indoor air conditioning unit, refer to Figure 5 , Figure 6 In some embodiments of this application, the indoor unit 100 of the air conditioner may include a fixing member 30, which is suitable for fixing the pipes 50 in the indoor unit of the air conditioner, especially fixing pipes such as low-pressure pipes.

[0070] refer to Figure 6 The indoor unit of the air conditioner may include a support 40, which is formed on the base 17 for mounting the fastener 30. (Reference) Figure 5 The fastener 30 is located in the second cavity 15, which allows it to fix the pipe structure at the end of the indoor heat exchanger 20. The pipe structure is located in the second cavity and will not interfere with the heat exchange airflow in the first cavity 14.

[0071] Among them, reference Figure 6The pipe 50 can be arranged at the top of the support part 40. The support part 40 and the base 17 can be manufactured as a single piece, reducing the number of parts, eliminating assembly tolerances, improving structural strength, and reducing production costs and assembly processes. Of course, the support part 40 and the base 17 can also be a separate structure, which can be connected and fixed by means of threaded connection or other methods.

[0072] It should be noted that multiple support parts 40 can be set on the base 17 according to the layout requirements of the pipeline 50. Each support part 40 can be a completely identical structure or a similar columnar structure. No limitation is made here.

[0073] In some embodiments of this application, in order to reduce costs and improve production efficiency, the support portion 40 may be arranged in a hollow cuboid shape.

[0074] For example, the base 17 may include a rear panel 171 opposite to the front panel 161, and the support portion 40 may be formed by recessing a portion of the rear panel 171 toward the front panel 161 to save materials and reduce the overall weight of the air conditioner indoor unit.

[0075] Continue to refer to Figure 6 The indoor unit 100 of the air conditioner may include a snap-fit ​​structure 7, which is provided on the support part 40 and is used to install the fastener 30.

[0076] The snap-fit ​​structure 7 may include two snap-fit ​​parts, which are spaced apart on the support part 40. The two snap-fit ​​parts provide two constraint points for the fastener 30. The two spaced snap-fit ​​parts form a deterministic linear constraint, which prevents the fastener 30 from rotating around a single point under transportation vibration or drop impact, and ensures that the clamping direction of the fastener 30 remains constant.

[0077] The fastener 30 includes two clamping arms disposed opposite each other, each clamping arm having a first end and a second end disposed opposite each other along its own extending direction. (Reference) Figure 7 The first ends of the two clamping arms are connected to define a clamping space for accommodating the pipe 50. The clamping arms extend along a second direction, which is perpendicular to the first direction and the height direction.

[0078] For example, refer to Figure 7 The first ends of the two clamping arms are connected in an arc shape. The fastener 30 can be roughly shaped like the letter "n". The connection between the two clamping arms can be an arched structure or an arc shape with multiple segments connected in sequence. Here, the overall shape of the fastener is not limited.

[0079] It should be noted that at least one pipe 50 can be clamped in the clamping space, and the inner diameter of the clamping space is adapted to the outer diameter of the at least one pipe 50 being clamped, so as to fix the pipe 50.

[0080] The fastener 30 may include two hooks, each located at the second end of one of the two clamping arms. Each hook is adapted to and connected to one of the two engaging portions, allowing the fastener 30 to engage with the support portion 40. The hooks and engaging portions facilitate installation, improving the installation efficiency of the fastener 30, eliminating the need for screws, and simplifying production and maintenance.

[0081] In order to improve the anti-detachment effect of the fastener 30, in some embodiments of this application, the fastener 30 may include an elastic cantilever 5. When the elastic cantilever 5 is squeezed by external force, it can press the two hooks together and lock them with the two locking parts to meet the anti-detachment requirements during transportation and drop.

[0082] Specifically, the hooks are located on the side of the clamping arm opposite to the first side plate 172. That is, the two hooks have the same snap-fit ​​direction and are opposite to the first side plate 172. This arrangement allows the hooks to snap into the snap-fit ​​part of the support 40 from a unified direction, which facilitates installation and visual positioning. At the same time, the snap-fit ​​direction is opposite to the first side plate 172, avoiding structural interference between the hooks and the first side plate 172, reserving sufficient space for the subsequent arrangement of the elastic cantilever 5, and realizing a compact structure and functional zoning design.

[0083] Continue to refer to Figure 7 Define the clamp arm closer to the first side plate 172 as the first clamp arm 1, the hook on the first clamp arm 1 as the first hook 3, and the other clamp arm as the second clamp arm 2, the hook on the second clamp arm 2 as the second hook 4.

[0084] The elastic cantilever 5 is located on the side of the first clamping arm 1 near the first side plate 172, with its free end abutting against the first side plate 172. In other words, the elastic cantilever 5 and the hooks (i.e., the first hooks 3) on the first clamping arm 1 are located on opposite sides of the first clamping arm 1. This arrangement allows for direct application of compressive force to the elastic cantilever 5 using the existing first side plate 172. Furthermore, the opposite arrangement of the elastic cantilever 5 and the first hooks 3 directly and without damage converts the compressive force into a clamping force between the two hooks and the locking parts. The elastic cantilever 5 remains under compression, ensuring a continuous and stable clamping force on both hooks.

[0085] refer to Figure 7 , Figure 8 In some embodiments of this application, the elastic cantilever 5 is inclinedly disposed at the second end of the first clamping arm 1, and the free end of the elastic cantilever 5 extends toward the front panel 161. That is, the extension direction of the elastic cantilever 5 and the extension direction of the first clamping arm 1 form an acute angle toward the opening of the front panel 161.

[0086] The inclined elastic cantilever 5 allows its free end to naturally tilt towards the first side plate 172. When the fixing member 30 is installed in a direction away from the front panel 161, the direction of the compressive force of the first side plate 172 on the elastic cantilever 5 is highly consistent with the direction of the cantilever's compression deformation, allowing it to smoothly abut and generate elastic compression. The acute angle setting can efficiently convert the pressure of the side plate into a tangential component force that drives the first hook 3 to move towards the other hook, ensuring that the two hooks obtain a continuous and stable clamping force, thereby forming a reliable friction lock.

[0087] Furthermore, the acute-angle opening faces the front panel 161, so that when the whole machine is subjected to an impact in a direction away from the front panel 161 (such as a transport drop), the first side panel 172 can prevent the fastener 30 from detaching from the support 40.

[0088] refer to Figure 12 When the fastener 30 is snapped onto the support 40, the free end of the elastic cantilever 5 abuts against the first side plate 172. Under the pressure of the first side plate 172, the elastic cantilever 5 applies a clamping force to the first hook 3, causing it to move toward the other hook (second hook 4), so that the two first hooks 3, the second hook 4 and the corresponding snapping parts form an anti-detachment structure.

[0089] In this embodiment, when the fastener 30 is snapped onto the support 40, the existing first side plate 172 of the air conditioner indoor unit presses against the elastic cantilever 5, ensuring that the two hooks remain tightly attached to the snapping part, forming a stable anti-detachment structure and continuously maintaining a locked state. This prevents the hooks from falling off due to the random movement of the fastener 30 during transportation or drops, especially when subjected to impacts away from the front panel 161. This significantly enhances the vibration and impact resistance of the fastener 30 snapping, thereby improving the fixing reliability of the pipeline 50.

[0090] During installation, the fastener 30 is first aligned with the first hook 3 and the second hook 4, respectively, at the two locking parts. There is no need to pinch or compress the fastener 30 by hand; simply press it downwards to achieve rapid installation, improving efficiency. Compared to existing technologies, this method does not alter the structure of the indoor air conditioning unit; only the structure of the fastener 30 is improved. The connection between the hooks and locking parts is locked by the deformation of the elastic cantilever 5 itself, making the entire installation process simple and convenient.

[0091] The support portion 40 has side walls on all four sides and a support top wall on the end face of the support portion 40. The support top wall is positioned facing the front panel 161.

[0092] refer to Figure 10 , Figure 12The support part 40 is a three-dimensional enclosed box structure, which enhances the deformation resistance of the support part 40 and provides a stable installation foundation for the fastener 30.

[0093] The two engaging portions are designated as first engaging portion 71 and second engaging portion 72. The sidewall facing the first sidewall among the plurality of sidewalls of the support portion 40 is defined as the support sidewall, as shown in the reference. Figure 10 The first snap-fit ​​part 71 is provided on the support side wall. The first snap-fit ​​part 71 is adapted to be connected to the first snap hook 3.

[0094] By placing the first locking portion 71 on the support sidewall, directly opposite the elastic cantilever 5 on the first side plate 172, a lateral locking point is formed. This arrangement allows the clamping force of the elastic cantilever 5 to act perpendicularly on the first locking portion 71, achieving efficient lateral locking.

[0095] The second latching part 72 is provided on the top support wall of the support part 40 facing the front panel 161, and is adapted to be connected with the second latch 4. In this embodiment, the first side plate 172 is arranged approximately perpendicular to the front panel 161.

[0096] By placing the second locking part 72 on the top wall of the support, forming a top locking point with the second hook 4, a second locking is achieved. The second locking part 72 and the first locking part 71 work together to form a multi-point spatial constraint, which restricts the displacement of the fastener 30 in multiple directions, thereby enhancing the overall stability and anti-shaking ability.

[0097] In this embodiment, both the first snap-fit ​​part 71 and the second snap-fit ​​part 72 are snap-fit ​​slots. The snap-fit ​​slot structure is simple and facilitates the sliding and snap-fit ​​of the first snap hook 3 and the second snap hook 4.

[0098] For example, in this embodiment, the two snap-fit ​​portions may be spaced apart along the first direction.

[0099] In some embodiments of this application, the first hook 3 may include a limiting portion 31, which extends along the length direction of the first clamping arm 1. (See reference...) Figure 8 The limiting part 31 is spaced apart from the first clamping arm 1 to limit the displacement of the first hook 3 in the direction perpendicular to the support side wall.

[0100] Specifically, the limiting part 31 and the first clamping arm 1 are spaced apart to form a groove, which constrains the support sidewall within the groove and precisely limits the displacement freedom of the first hook 3 in the direction perpendicular to the support sidewall.

[0101] The first hook 3 may include a first abutting portion 32, which is connected to the end of the first clamping arm 1 and the limiting portion 31 that is away from the front panel 161. (See reference) Figure 8 , Figure 12The first abutting part 32 is inserted into the first snap-fit ​​part 71, and the first abutting part 32 abuts against the side wall of the first snap-fit ​​part 71 near the front panel 161, so that the first clamping arm 1 is snapped and fixed to the support part 40.

[0102] The first abutting part 32 abuts against the side wall of the first locking part 71 near the front panel 161, forming a forward limiting buckle. When the fastener 30 is impacted in the direction of the front panel 161, the side wall that abuts against the first abutting part 32 directly bears the impact load, preventing the first hook 3 from coming out forward.

[0103] In this embodiment, when the elastic cantilever 5 is in a compressed state, the first hook 3 is restricted from displacement in the direction perpendicular to the support side wall and in the direction perpendicular to the front panel 161 by the cooperation of the limiting part 31 and the first abutting part 32, thereby achieving limiting in four directions, ensuring that the first hook 3 will not accidentally come out after being engaged, and enhancing the firmness of the engagement.

[0104] In some embodiments of this application, a disassembly structure 6 is provided on the side of the first clamping arm 1 near the first side plate 172, and the disassembly structure 6 and the elastic cantilever 5 are spaced apart in the extending direction of the first clamping arm 1.

[0105] Specifically, applying a pressing force away from the first sidewall to the disassembly structure 6 causes the first hook 3 to disengage from the corresponding engaging part, namely the first engaging part 71.

[0106] In this embodiment, the disassembly structure 6 and the first hook 3 are spaced apart on the first clamping arm 1 to form a lever connection. The first hook 3 serves as the other end of the lever where the disassembly structure 6 is located. When the disassembly structure 6 is pressed, the first hook 3 can be disengaged from the corresponding locking part through the lever action and the elastic deformation of the first clamping arm 1 when the disassembly structure 6 is under force, thereby achieving convenient disassembly without tools and improving disassembly efficiency.

[0107] In some embodiments of this application, reference is made to Figure 7 , Figure 8 The disassembly structure 6 may include a pressing cantilever 61, which extends along the length of the first clamping arm 1.

[0108] The end of the pressing cantilever 61 that is away from the front panel 161 is connected to the first clamping arm 1, and the free end of the pressing cantilever 61 is spaced apart from the first clamping arm 1.

[0109] In this embodiment, the design of pressing the cantilever 61 provides an intuitive and effortless operation method; the user only needs to press the free end to trigger the disassembly mechanism. (See reference...) Figure 13When external force is applied by pressing the cantilever 61, since it and the first hook 3 form the two ends of the lever, pressing the cantilever 61 deforms and drives the first hook 3 to move away from the second hook 4, so that the first hook 3 is disengaged from the first locking part 71. The user can then lift the fixing part 30 upward to complete the disassembly, which reduces the user's operation difficulty.

[0110] In some embodiments of this application, the disassembly structure 6 may include a reinforcing rib 62, which is disposed between the pressing cantilever 61 and the elastic cantilever 5. The reinforcing rib 62 is integrally formed with the first clamping arm 1 to enhance the structural strength of the first clamping arm 1.

[0111] In some applications, the communication cable between the indoor and outdoor units of an air conditioner often needs to be fixed in place to prevent it from shaking and affecting the operation of other components. In some embodiments of this application, the press-fit cantilever 61 can be used as a cable clamp.

[0112] refer to Figure 8 Pressing the cantilever 61 and the first clamping arm 1 forms a cable routing groove 64, which is used for cable routing and fixing.

[0113] To improve the stability of the cable tray 64 in fixing the connecting wires and prevent the connecting wires from coming out of the cable tray 64, in some embodiments of this application, the disassembly structure 6 may include a stop 63, which is disposed at the free end of the pressing cantilever 61. (Continue to refer to...) Figure 8 The stop portion 63 protrudes from the side of the pressing cantilever 61 near the first clamping arm 1, and is used to restrict the cable from coming out of the cable tray 64.

[0114] In this embodiment, the cable is fixed by utilizing the cable routing space naturally formed by the pressing cantilever 61 and the first clamping arm 1. At the same time, the stop part 63 plays a limiting role at the free end, thereby expanding the function of the fixing part 30, solving the problem of inconvenient cable routing and management inside the air conditioner indoor unit, and improving the overall integrity and safety of the product.

[0115] In the embodiments of this application, the first clamping arm 1, the second clamping arm 2, the elastic cantilever 5, the pressing cantilever 61, and the first hook 3 and the second hook 4 can be integrally molded and manufactured by injection molding. This arrangement improves the convenience of production and manufacturing, reduces manufacturing costs, and makes the operation of individual components more convenient and reliable during the process of fixing the pipeline 50 and the connecting line.

[0116] In some embodiments of this application, at least one end of the hook away from the front panel 161 is provided with a guide surface 8.

[0117] In this embodiment, the guide surface 8 is provided at the ends of the first hook 3 and the second hook 4, which can guide the first hook 3 and the second hook 4 to smoothly enter the corresponding locking part, reduce installation resistance, and allow direct pressing operation when the fastener 30 is installed, thereby improving installation efficiency, solving the problem of difficulty in aligning the hook and locking part during installation, and simplifying the production and assembly process.

[0118] In the embodiments of this application, the first clamping arm 1 and the second clamping arm 2 are arranged substantially parallel to each other, and the first clamping arm 1 and the second clamping arm 2 extend along the axial direction of the centrifugal fan. This arrangement allows the fastener 30 to be installed on the base 17 by aligning the hooks on the two clamping arms with the two snap-fit ​​parts on the support 40 and pressing it down directly, which greatly improves the installation efficiency.

[0119] In the embodiments of this application, reference is made to Figure 8 The second latch 4 may include an insertion part 41, which is located at the second end of the second clamping arm 2. The insertion part 41 is inserted into the corresponding latching part, namely the second latching part 72.

[0120] The second hook 4 may include a second abutment portion 42, which is connected to the insertion portion 41. The second abutment portion 42 extends in a direction away from the second clamping arm 2, and the second abutment portion 42 abuts against the side wall of its corresponding latching portion, namely the second latching portion 72, so that the second clamping arm 2 is latched and fixed to the support portion 40.

[0121] In this embodiment, the insertion part 41 is easy to insert into the snap-fit ​​part, and the second abutting part 42 abuts against the side wall of the snap-fit ​​part to form a mechanical lock. The insertion part 41 and the second abutting part 42 ensure that the second hook 4 is reliably snapped into the snap-fit ​​part, so that the first clamping arm 1 will not accidentally come out.

[0122] In some embodiments of this application, the dimension L1 of the fastener 30 in the extension direction of the clamping arm and the extension length L2 of the disassembly structure 6 satisfy: L1≥50mm, L2≥25mm; wherein, the height of the free end of the disassembly structure 6 does not exceed the height of the end of the fastener 30 near the front panel 161.

[0123] If L1 < 50mm and L2 < 25mm, the pressing force of the disassembly structure 6 when removing the fastener 30 is too great, far exceeding the range of force that the human body can comfortably exert, and the difficulty of operation increases sharply.

[0124] In addition, if L1 < 50mm, the clamping arm is too short, resulting in insufficient rigidity. Under the continuous clamping force of the elastic cantilever, the stress concentration at the root is severe, which easily leads to brittle fracture and a low service life of the fastener 30.

[0125] If the length L2 of the disassembly structure 6 is less than 25mm, not only will the contact area between the fingers of production line personnel and the structure be small, making it easy to slip during operation, but the deformation generated by the disassembly structure will also be small, which is insufficient to drive the first hook to completely disengage from the constraint of its locking part, thus affecting the disassembly efficiency.

[0126] In this embodiment, by setting L1≥50mm and L2≥25mm, it is effectively ensured that when force is applied to the upper disassembly structure 6, the lower first hook 3 can be completely disengaged from the corresponding snap-fit ​​part, thus achieving easy disassembly and reducing the difficulty of operation.

[0127] The extension length L2 of the disassembly structure can be the extension length of the first clamping arm 1.

[0128] Preferably, L2 / L1 can be controlled between 0.5 and 0.7. Under this size ratio, the stiffness of the first clamping arm 1 matches the flexibility of the pressing cantilever 61, and the operating force is balanced with the unlocking stroke.

[0129] In some other embodiments, the support portion 40 is provided with two snap-fit ​​portions at intervals. The fastener 30 may include a second clamping arm 2, the second end of which is provided with a second hook 4 protruding in a direction away from the first side plate 172, and the second hook 4 is adapted to be connected to a snap-fit ​​portion away from the first side plate 172.

[0130] The fastener 30 may include a first clamping arm 1, which is disposed opposite to a second clamping arm 2. The first end of the second clamping arm 2 is connected to the first end of the first clamping arm 1 to define a clamping space near the connection point. The clamping space is used to accommodate the pipeline.

[0131] Furthermore, the fastener 30 may include an elastic hook structure, which is located at the second end of the first clamping arm 1.

[0132] The elastic hook structure has a first hook 3 protruding in a direction away from the first side plate 172, and the first hook 3 is adapted to connect with another locking part. When the fastener 30 is locked onto the support part 40, the first side plate 172 exerts a compressive force on the elastic hook structure. Under the action of the compressive force, the first hook 3 tends to move towards the second hook 4, so that the second hook 4, the first hook 3 and the corresponding locking part form an anti-detachment structure.

[0133] In this embodiment, the first hook 3 tends to move toward the second hook 4 due to the squeezing force of the first side plate 172 on the elastic hook structure, forming an anti-detachment structure to prevent the hook from falling off due to the random movement of the fastener 30 during transportation and drops. In particular, it will not disengage when subjected to an impact in a direction away from the front panel 161, thus improving the reliability of the fastening.
