Description

Technical Field

[0001] The utility model relates to the field of air conditioning, in particular to an air conditioner and an air conditioner indoor unit thereof. Background Art

[0002] Throughout the history of air conditioning, traditional wall-mounted units have been widely used in various residential and commercial spaces due to their ease of installation and stable heat exchange. These units typically require ample overhead space to hang and secure the unit to the bracket from top to bottom.

[0003] With the diversification of interior decoration styles and the improvement of space utilization, cabinet-mounted air conditioners have emerged and are gradually gaining popularity, especially for those who pursue a clean, beautiful interior environment and efficient use of space. A cabinet-mounted air conditioner embeds the indoor unit into a custom or existing cabinet. This not only conceals the air conditioner's appearance and maintains the integrity of the interior decoration, but also effectively reduces dust accumulation and improves the comfort of the home or office environment.

[0004] However, this installation method also brought new challenges: due to the limited cabinet space, especially the limited vertical clearance, the traditional wall-mounted installation method was no longer suitable. Therefore, a new fixing and installation solution designed specifically for cabinet-mounted air conditioners was urgently needed. Utility Model Content

[0005] An object of the present invention is to overcome at least one defect in the prior art and to provide an air conditioner and an air conditioner indoor unit.

[0006] Another object of the present invention is to improve the installation convenience of the indoor unit of the air conditioner.

[0007] Another object of the present invention is to ensure that the appearance of the indoor unit of the air conditioner is beautiful.

[0008] In particular, the utility model provides an air conditioner indoor unit, comprising:

[0009] The casing has at least one slide groove extending in the front-to-back direction formed at the bottom thereof, the notch of the slide groove is exposed downward to the external space of the casing, and the rear end of the slide groove is open backward for inserting the slide rail of the bracket, so that the casing can be slidably supported on the slide rail of the bracket.

[0010] Optionally, there are two sliding grooves, and the two sliding grooves are arranged at intervals along the transverse direction of the housing.

[0011] Optionally, the ratio of the interval width between the two sliding grooves to the lateral width of the housing is in the range of 1:1.2 to 1:2.

[0012] Optionally, the width of the chute is 2 cm to 10 cm.

[0013] Optionally, the slide groove extends horizontally from the back to the front, or the slide groove extends obliquely upward from the back to the front.

[0014] Optionally, the housing includes:

[0015] a rear housing, the front side of which is open and defines a receiving space therein; and

[0016] The front frame is detachably connected to the rear housing and is used to cover the opening on the front side of the rear housing.

[0017] Optionally, the front frame includes:

[0018] A main frame, the upper area of which is provided with an air inlet, and the lower area of which is provided with an air outlet; and

[0019] The front panel has a lower end pivotally mounted on the main frame and is configured to be controlled to turn up and down around a pivot point to open and close the air inlet.

[0020] Optionally, an air inlet grille is provided in the air inlet, and the air inlet grille includes a plurality of grille bars, and the plurality of grille bars are arranged in a crisscross manner in the air inlet.

[0023] The air conditioner indoor unit of the present invention has at least one slide groove extending in a front-to-back direction formed on the bottom of its casing. The notch of the slide groove is exposed downward to the exterior space of the casing, and the rear end is open rearward. Thus, during installation, the user only needs to pre-fix the bracket at an appropriate height on a cabinet or other installation location, ensuring the correct position of the slide rails. Then, the user lifts the casing of the air conditioner indoor unit, aligns the slide rails on the bracket, and pushes the casing from front to back, guided by the slide groove, until it reaches the preset installation position. The entire installation process requires no complex tools and is simple and quick to operate. This not only improves installation efficiency but also significantly saves installation space, allowing the air conditioner indoor unit to be more flexibly integrated into various home environments.

[0024] Furthermore, the air conditioner indoor unit of the present invention has a housing consisting of a rear housing and a front frame. The chute is formed on the rear housing, while the front frame shields the chute from the front. This design effectively conceals the chute and its connection to the rail, preventing direct external visibility.

For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0044] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0045] The utility model provides an air conditioner and an air conditioner indoor unit thereof, aiming to solve the problem that the existing air conditioner indoor unit is inconvenient to install in a cabinet.

[0046] Air conditioners are generally divided into single-unit air conditioners, where all components are housed within a single unit, and split-unit air conditioners, where all components are housed in separate indoor and outdoor units. The following description of the present invention relates to an embodiment of a split-unit air conditioner. Furthermore, the indoor unit of the present invention is used in conjunction with an outdoor unit of the same type as a conventional outdoor unit, so the description of the outdoor unit will be omitted.

[0047] Figure 1 1 is a schematic structural diagram of an air conditioner indoor unit 10 with the air inlet 101 in a closed state according to an embodiment of the present invention. Figure 2 1 is a schematic structural diagram of an air conditioner indoor unit 10 with the air inlet 101 in an open state according to an embodiment of the present invention. Figure 3 1 is a schematic exploded view of a housing 100 of an air-conditioning indoor unit 10 according to an embodiment of the present invention. Figure 4 1 is a schematic cross-sectional view of an air-conditioning indoor unit 10 according to an embodiment of the present invention.

[0048] like Figures 1 to 4 As shown, the air conditioning indoor unit 10 may generally include a casing 100 , a frame 130 , a heat exchanger 140 and a cross-flow fan 150 .

[0049] The front side of the housing 100 is provided with an air inlet 101 and an air outlet 102. The air inlet 101 is located above the air outlet 102, allowing air to enter from the upper front and exit from the lower front of the air conditioner indoor unit 10. When the air conditioner indoor unit 10 is installed in a space-constrained area such as a cabinet, the upper front air inlet and lower front air outlet configuration is not restricted by the cabinet's top and bottom walls, eliminating the need to worry about airflow obstruction or insufficient space, thereby improving the installation adaptability of the air conditioner indoor unit 10.

[0050] In one example, the housing 100 can be composed of two parts, including a rear shell 110 and a front frame 120. The front side of the rear shell 110 is open and defines a storage space inside. The front frame 120 is detachably connected to the rear shell 110 to cover the opening on the front side of the rear shell 110.

[0051] The rear housing 110 is primarily used to house components such as the frame 130, heat exchanger 140, and cross-flow fan 150. Since the front side of the rear housing 110 is open, when the air conditioner indoor unit 10 malfunctions, the exposed components can be directly inspected and repaired by removing the front frame 120, which facilitates convenient maintenance.

[0052] The front frame 120 may include a main frame body 121 and a front panel 122. The upper area of the main frame body 121 is provided with the aforementioned air inlet 101, and the lower area is provided with the aforementioned air outlet 102. The lower end of the front panel 122 can be pivotally mounted on the main frame body 121 and is configured to be controlled to flip up and down around the pivot point to open and close the air inlet 101.

[0053] During the use of the air-conditioning indoor unit 10, if the airflow between the air inlet 101 and the air outlet 102 is not properly isolated and guided, upward and downward air movement may occur, that is, cold air and hot air mix with each other inside the casing 100, resulting in reduced heat exchange efficiency and even affecting the uniformity of the indoor temperature.

[0054] In this embodiment, when the front panel 122 is flipped forward and opened, it acts as a barrier to guide airflow, ensuring that the cold or hot air entering from the air inlet 101 flows along a predetermined path, exchanges heat through the heat exchanger 140, and is then discharged from the air outlet 102. At the same time, the front panel 122 prevents the air discharged from the air outlet 102 from directly flowing back into the air inlet 101, effectively avoiding the problem of upward and downward airflow.

[0055] In one example, an air inlet grille 123 is provided within the air inlet 101. The air inlet grille 123 may include a plurality of grille bars arranged in a crisscross pattern within the air inlet 101. The staggered arrangement of the grille bars forms an orderly grid structure, making the main frame 121 more stable when subjected to external pressure and impact, and reducing the risk of deformation and damage.

[0056] The frame 130 is disposed within the housing 100, specifically within the rear shell 110 of the housing 100. A heat exchange duct extending laterally is formed on the frame 130. The heat exchanger 140 is mounted on the frame 130 and covers the heat exchange duct to exchange heat with air drawn into the housing 100 through the air inlet 101.

[0057] The cross-flow fan 150 is installed in the heat exchange duct along the horizontal direction to promote indoor air to enter the casing 100 from the air inlet 101 to exchange heat with the heat exchanger 140, and discharge the heat-exchanged air from the air outlet 102, thereby finally achieving indoor temperature regulation.

[0058] Figure 5 1 is a schematic structural diagram of an air-conditioning indoor unit 10 in an inverted state according to an embodiment of the present invention. Figure 6 1 is a schematic structural diagram of the rear housing 110 of the air-conditioning indoor unit 10 according to an embodiment of the present invention. Figure 7 1 is a schematic structural diagram of a skeleton 130 of an air-conditioning indoor unit 10 according to an embodiment of the present invention. Figure 8 1 is a schematic structural diagram of the frame 130 of the air-conditioning indoor unit 10 in an inverted state according to an embodiment of the present invention. Figure 9 1 is a schematic bottom view of an air-conditioning indoor unit 10 according to an embodiment of the present invention. Figure 10 1 is a schematic assembly diagram of an air-conditioning indoor unit 10 and a bracket 200 according to an embodiment of the present invention.

[0059] like Figure 5 and Figure 10 As shown, the bottom of the casing 100 can be formed with at least one slide groove 115 extending in the front-to-back direction, the notch of the slide groove 115 is exposed downward to the external space of the casing 100, and the rear end of the slide groove 115 is open backward for the slide rail 220 of the bracket 200 to be inserted, so that the casing 100 can be slidably supported on the slide rail 220 of the bracket 200.

[0060] During installation, the user simply secures the bracket 200 at an appropriate height on a cabinet or other mounting location, ensuring the correct positioning of the slide rails 220. The user then lifts the housing 100 of the air conditioner indoor unit 10, aligns it with the slide rails 220 on the bracket 200, and pushes the housing 100 from front to back, guided by the slide grooves 115, until it reaches the pre-set mounting position. The entire installation process requires no complex tools and is simple and quick to operate, improving installation efficiency while significantly saving installation space, allowing the air conditioner indoor unit 10 to be more flexibly integrated into various home environments.

[0061] like Figure 6As shown, the rear shell 110 of the casing 100 has a bottom plate 114, which is recessed upward to form at least one slide groove 115 extending in the front-to-back direction, and the rear end of the slide groove 115 is open for inserting the slide rail 220 of the bracket 200, so that the casing 100 can be operably slidably installed on the bracket 200 from front to back.

[0062] Of course, the above examples are merely illustrative. Based on the understanding of the above embodiments, those skilled in the art should be able to easily expand and transform the formation method of the slide groove 115 of this embodiment. For example, the original structure of the housing 100 is retained, and a structural member is added to the bottom of the housing 100 (which may increase the height of the entire machine), and a slide groove 115 is formed on the structural member for inserting the slide rail 220. Such expansion and transformation should also fall within the scope of protection of the present utility model.

[0063] The bottom of the housing 100 may be provided with two slide grooves 115, which are spaced apart along the transverse direction of the housing 100. Accordingly, two slide rails 220 may also be provided, and the interval width between the two slide rails 220 is substantially the same as the interval width between the two slide grooves 115.

[0064] During the installation process, the two slide rails 220 can be inserted into the corresponding two slide grooves 115 respectively, and the two slide rails 220 can be used to jointly support the air-conditioning indoor unit 10 stably, making the installation of the air-conditioning indoor unit 10 more firm and reliable, and effectively reducing the shaking caused by external force.

[0065] It is worth noting that the notches of both slide grooves 115 are exposed downward. This allows the installer to visually see the position and shape of the slide grooves 115 from below during installation, making it easier to align and insert the slide rails 220 of the bracket 200 directly into the slide grooves 115 from below. This design avoids installation difficulties caused by obstructions or space limitations, thereby improving installation efficiency.

[0066] The two slide grooves 115 can be distributed on both sides below the frame 130. When the two slide rails 220 are respectively inserted into the two slide grooves 115, they form a tight and stable fit with each other, which not only can evenly distribute the weight of the housing 100, but also prevent the housing 100 from shaking or becoming unstable due to excessive concentration of load.

[0067] In one example, the rear shell 110 is roughly square in shape, and includes a top plate 111, a left side plate 112, a right side plate 113, a left bottom plate 114a and a right bottom plate 114b, wherein the top plate 111 forms the top boundary of the rear shell 110, the left side plate 112 and the right side plate 113 extend downward from the left and right side edges of the top plate 111 respectively, forming the two side boundaries of the rear shell 110, the left bottom plate 114a extends horizontally from the lower edge of the left side plate 112 toward the right side plate 113, and the right bottom plate 114b extends horizontally from the lower edge of the right side plate 113 toward the left side plate 112, and together with the left bottom plate 114a form the bottom boundary of the rear shell 110.

[0068] A gap is left between the left and right bottom plates 114a, 114b. The bottom of the frame 130 is located between the left and right bottom plates 114a, 114b. Its lower surface is substantially flush with the lower surfaces of the left and right bottom plates 114a, 114b, and serves as the middle bottom plate 114 of the rear housing 110. This layout helps optimize the internal spatial layout of the rear housing 110, allowing the air outlet 102 on the front side of the housing 100 to be closer to the bottom of the front frame 120. This not only meets the aesthetic requirements of the design, but also improves the efficiency of air circulation.

[0069] In one example, the left bottom plate 114a and the right bottom plate 114b are spaced apart and each is recessed upward to form a chute 115. Specifically, the chute 115 on the left bottom plate 114a is formed by first bending the right side of the left bottom plate 114a vertically upward (forming the left side wall of the chute 115), then bending horizontally to the right (forming the top wall of the chute 115); the chute 115 on the right bottom plate 114b is formed by first bending the right side of the right bottom plate 114b vertically upward (forming the right side wall of the chute 115), then bending horizontally to the left (forming the top wall of the chute 115).

[0070] The distance between the left side wall of the left chute 115 and the right side wall of the right chute 115 can be approximately equal to the distance between the two sides of the two slide rails 220 that are facing away from each other. When the air conditioner indoor unit 10 is placed on the bracket 200 and properly installed with the slide rails 220 and the chute 115 engaged, this design effectively prevents the air conditioner indoor unit 10 from rocking left and right on the bracket 200, facilitating stable operation of the air conditioner.

[0071] In addition, a stable installation base can reduce vibration and noise during machine operation, extend the service life of the air conditioner, and enhance the user experience.

[0072] Since the housing 100 is divided into two parts, the rear housing 110 and the front frame 120, the slide groove 115 is formed on the rear housing 110. In this way, by designing the size of the front frame 120, the front frame 120 can block the slide groove 115 from the front side of the slide groove 115.

[0073] This design effectively hides the slide groove 115 and the connection part with the slide rail 220, avoiding direct contact with the outside sight, making the appearance of the entire air-conditioning indoor unit 10 more simple and smooth, without any abrupt feeling, and significantly improving the overall aesthetics of the home decoration.

[0074] In an optional embodiment, the slide groove 115 can extend horizontally from the back to the front. Correspondingly, the slide rail 220 on the bracket 200 also extends horizontally from the back to the front.

[0075] Since the horizontal extension direction of the slide groove 115 and the slide rail 220 is consistent with the installation direction, the installer can more easily and smoothly push the air conditioner indoor unit 10 into the cabinet along the slide rail 220. This linear installation method not only simplifies the operation steps, but also reduces the risk of errors and damage that may occur during the installation process.

[0076] Especially when the size of the cabinet matches the size of the air-conditioning indoor unit 10, this installation method can ensure that the gap between the air-conditioning indoor unit 10 and the cabinet wall panel is extremely small, or even almost seamless, so that the air-conditioning indoor unit 10 is integrated with the cabinet.

[0077] In another optional embodiment, the slide groove 115 can extend upwardly and obliquely from the back to the front. Correspondingly, the slide rail 220 on the bracket 200 also extends upwardly and obliquely from the back to the front.

[0078] While this design doesn't allow for seamless, embedded installation, it's particularly well-suited for environments where external forces may push or vibrate, such as in public places or in areas around homes where children run around. By increasing the inclination angles of the chute 115 and the rail 220, the air conditioner indoor unit 10 remains in place even under external forces, thanks to gravity and the guidance of the chute 115. It won't easily slide off.

[0079] In one example, the ratio of the interval width of the two slide slots 115 to the lateral width of the housing 100 is in the range of 1:1.2 to 1:2. For example, 1:1.2, 1:1.5, 1:1.8, 1:2, etc. Figure 6 As shown, the spacing width of the two slide grooves 115 refers to the distance between the right edge of the left bottom plate 114a and the left edge of the right bottom plate 114b, and the lateral width of the casing 100 refers to the distance between the outer surface of the left side plate 112 of the rear shell 110 and the outer surface of the right side plate 113.

[0080] It is understandable that when the two chute slots 115 are too close together, the housing 100 may be susceptible to shaking or even falling when subjected to left and right external forces due to insufficient support points. This risk is particularly significant when the housing is installed directly on a wall without additional support from external structures such as cabinets. Therefore, by setting a reasonable ratio between the gap width and the lateral width of the housing 100, this situation can be effectively avoided.

[0081] In one example, the width of the slide groove 115 is 2 cm to 10 cm, for example, 2 cm, 4 cm, 6 cm, 8 cm, 10 cm, etc.

[0082] In an optional embodiment, a first reinforcement member 160 corresponding to the slide slot 115 is provided on the frame 130 . The first reinforcement member 160 covers the slide slot 115 and is buckled onto the bottom plate 114 .

[0083] The first reinforcement member 160 is primarily used to structurally reinforce the slide groove 115 of the housing 100, effectively preventing the housing 100 from deforming in the slide groove 115 due to external forces. This reinforcement ensures greater stability and reliability when the slide rail 220 slides smoothly into the slide groove 115, reducing the risk of poor sliding or loose structure caused by deformation of the housing 100 and ensuring a tight fit and long-term durability between the slide rail 220 and the slide groove 115.

[0084] In one example, the first reinforcement member 160 includes a first reinforcement plate 161 and a second reinforcement plate 162, wherein the first reinforcement plate 161 extends horizontally in the front-to-back direction at the top of the slide groove 115, and the second reinforcement plate 162 extends vertically downward from both sides of the first reinforcement plate 161, and together with the first reinforcement plate 161 defines a buckle groove 163 for buckling the bottom plate 114.

[0085] Specifically, the first reinforcing plate 161 provides a solid top support for the slide groove 115 area, which not only enhances the upper strength of the slide groove 115, but also helps to disperse the force from the upper direction or the front and rear directions to prevent the housing 100 from deforming in these directions.

[0086] The second reinforcing plate 162 and the first reinforcing plate 161 together define a snap groove 163 for snapping into the bottom plate 114. This snap groove 163 utilizes the geometric shapes of the first and second reinforcing plates 162 to enable the first reinforcing member 160 to be securely snapped onto the bottom plate 114, forming a stable and tight connection with the bottom plate 114.

[0087] This structural design not only enhances the local strength of the housing 100 in the area of the slide slot 115, but also improves the stability of the entire frame 130 through the tight connection between the locking groove 163 and the bottom plate 114. When the slide rail 220 slides into the slide slot 115, this stable structure ensures smooth engagement between the slide rail 220 and the slide slot 115.

[0088] In an optional embodiment, the first reinforcement 160 is formed by extending outward from the main body of the frame 130. This design allows a seamless connection between the first reinforcement 160 and the frame 130, thereby enhancing the overall structural integrity and strength.

[0089] The first reinforcement 160 can be directly extended from the main material of the skeleton 130 by stamping, bending or other metal processing techniques. This not only reduces the number of connection points between components and reduces the risk of loose connections or failures, but also simplifies the production process and improves production efficiency.

[0090] In some alternative embodiments, the first reinforcement 160 is detachably connected to the main body of the frame 130. That is, the first reinforcement 160 is added to the frame 130 as a separate component, thus eliminating the need to modify the original mold of the frame 130. This design avoids the high costs and long development cycles associated with mold modification or redesign.

[0091] Furthermore, the first reinforcement 160 is detachably connected to the main body of the frame 130, allowing the material of the first reinforcement 160 to be independently selected based on its function and required strength, without being limited by the material selection of the frame 130. This allows the first reinforcement 160 to be made of a lower-cost material that still meets the required performance, thereby further reducing costs.

[0092] A reinforcement rib 164 is provided between the first reinforcement plate 161 and the main body of the frame 130. There may be a plurality of reinforcement ribs 164, which are arranged at intervals along the front-to-back direction.

[0093] The reinforcing ribs 164 can be L-shaped, comprising transverse and vertical ribs. The transverse ribs can be attached to the top of the first reinforcing plate 161 to ensure the horizontal stability of the first reinforcing plate 161, while the vertical ribs can be attached to the main body of the frame 130 to enhance the vertical connection strength. This effectively prevents the connection from breaking when subjected to external forces, thereby improving the reliability of the overall structure.

[0094] In an optional embodiment, a second reinforcement member 170 is provided in the slide groove 115 . The second reinforcement member 170 extends in the front-to-back direction and is fixed to the top wall of the slide groove 115 .

[0095] The main function of the second reinforcement member 170 is to share the load borne by the chute 115. When the chute 115 is subjected to vertical pressure, the second reinforcement member 170 can significantly enhance the compressive strength of the chute 115, prevent it from deformation or damage, and help maintain the original shape and dimensional accuracy of the chute 115.

[0096] In one example, the first reinforcement plate 161 of the first reinforcement member 160 and the second reinforcement member 170 can clamp the top wall of the chute 115 from top to bottom and are tightly connected together via connectors to form an integral force-bearing structural system. This synergistic effect further improves the stability and load-bearing capacity of the chute 115 and its surrounding area.

[0097] In an optional embodiment, a third reinforcement member 180 may be further provided at the bottom of the housing 100 . The third reinforcement member 180 extends in the transverse direction of the housing 100 and is used to connect the left bottom plate 114 a , the frame 130 and the right bottom plate 114 b .

[0098] On the one hand, third reinforcement member 180 enhances the structural integrity of the bottom of housing 100, improving the bending strength and rigidity of housing 100 when subjected to external forces. On the other hand, third reinforcement member 180 also serves to disperse the load, evenly transferring the pressure at the bottom of housing 100 to left bottom plate 114a and right bottom plate 114b, thereby reducing single-point stress and improving the durability of housing 100.

[0099] In addition, the present invention also provides a mounting assembly 20 for mounting the air conditioner indoor unit 10. Figure 11 is a schematic structural diagram of an installation assembly 20 according to an embodiment of the present invention, as shown in FIG. Figure 11 As shown, the mounting assembly 20 includes at least one bracket 200, and the bracket 200 may include a fixed rail 210 and a sliding rail 220. The fixed rail 210 extends in a vertical direction and is used to be fixedly connected to a wall or a cabinet. One end of the sliding rail 220 is connected to the lower end of the fixed rail 210, and the other end extends horizontally forward and is used to be inserted into the slide groove 115 at the bottom of the air-conditioning indoor unit 10 to support the air-conditioning indoor unit 10.

[0100] During installation, the user simply needs to secure the mounting rails 210 of the bracket 200 to the appropriate height of a cabinet or other mounting location, ensuring the correct positioning of the slide rails 220. The user then lifts the housing 100 of the air conditioner indoor unit 10, aligns it with the slide rails 220 on the bracket 200, and, guided by the slide grooves 115, pushes the housing 100 from front to back until it reaches the pre-set mounting position. The entire installation process requires no complex tools and is simple and quick to operate, improving installation efficiency while significantly saving installation space, allowing the air conditioner indoor unit 10 to be more flexibly integrated into various home environments.

[0101] In particular, when the cabinet dimensions match those of the air conditioner indoor unit 10, this installation method ensures minimal, or even virtually seamless, clearance between the indoor unit 10 and the cabinet wall, creating a seamless visual effect. This not only enhances the overall aesthetics of the home, making the air conditioner a part of the decor rather than an obtrusive presence, but also effectively prevents dust accumulation in gaps, easing cleaning difficulties and creating a more comfortable and convenient user experience.

[0102] In an optional embodiment, the sliding rail 220 and the fixed rail 210 may have different lengths, and the two can be used interchangeably.

[0103] In other words, the slide rails 220, originally designed to support and guide the air conditioner indoor unit 10, can be converted into fixed rails 210, allowing for secure installation in a cabinet or other installation location. In this case, the fixed rails 210, originally used as a fixed reference, are now used as slide rails 220. This interchangeable design greatly expands the application range of the bracket 200, making it easily adaptable to cabinet installation environments of varying depths.

[0104] In one example, the ratio of the length of the slide rail 220 to the length of the fixed rail 210 ranges from 1:1.2 to 1:2, for example, 1:1.2, 1:1.5, 1:1.8, 1:2, etc. This ratio range provides a variety of possible length combinations to accommodate different installation requirements.

[0105] Taking specific values as an example, if the length of the slide rail 220 is set to 20 cm, then according to the ratio range, the length of the fixed rail 210 can be between 24 cm and 40 cm, for example, the length of the fixed rail 210 is 30 cm.

[0106] The width of the sliding rail 220 and the fixed rail 210 can be 2 cm to 10 cm. For example, the width of the sliding rail 220 and the fixed rail 210 can be 2 cm, 4 cm, 6 cm, 8 cm, 10 cm, etc.

[0107] The slide rail 220 and the fixed rail 210 are both U-shaped rails. The U-shaped rails can more effectively disperse and bear the weight of the air conditioner indoor unit 10, reduce the risk of deformation or damage caused by excessive force on a single point, and ensure long-term reliability.

[0108] In addition, the side walls of the U-shaped rail provide additional support for the sliding rail 220 or the fixed rail 210, increasing their stability in the installed position. This stability helps reduce shaking caused by vibration or external forces, ensuring the smooth operation of the air conditioner indoor unit 10.

[0109] A reinforcing plate 230 is provided at the connection between the slide rail 220 and the fixed rail 210. The reinforcing plate 230 is mainly used to enhance the connection stability between the slide rail 220 and the fixed rail 210 and prevent the connection between the two from breaking due to stress concentration.

[0110] Preferably, the slide rail 220, the fixed rail 210, and the reinforcement plate 230 are integrally formed. This eliminates any additional seams between the slide rail 220, the fixed rail 210, and the reinforcement plate 230, thereby reducing potential weak points and more effectively distributing and bearing the weight and stress from the air conditioner indoor unit 10, thereby preventing breakage or deformation caused by stress concentration.

[0111] Furthermore, the integrated design reduces installation complexity. Users no longer need to separately install the slide rails 220, fixed rails 210, and reinforcement plates 230, nor worry about connecting them. This not only saves installation time but also reduces the risk of installation errors.

[0112] In an optional embodiment, the fixed rail 210 has two first fixing holes 211, which are spaced apart along the length of the fixed rail 210 and allow fasteners to pass through to connect the fixed rail 210 to a wall or cabinet. The sliding rail 220 has two second fixing holes 221, which are spaced apart along the length of the sliding rail 220 and allow fasteners to pass through to connect the sliding rail 220 to the air conditioner indoor unit 10.

[0113] The first fixing hole 211 can be a screw hole or a through hole. When the first fixing hole 211 is a screw hole, the fastener can be a screw. When the first fixing hole 211 is a through hole, the fastener can be a screw, a bolt, an anchor, etc.

[0114] Similarly, the second fixing hole 221 may also be a screw hole or a through hole.

[0115] In an alternative embodiment, there may be two brackets 200, with the two brackets 200 spaced laterally apart. The fixing rails 210 of the two brackets 200 are vertically fixed to a cabinet or other mounting location, allowing the two slide rails 220 to extend forward and backward to jointly support the air conditioner indoor unit 10. This makes the air conditioner indoor unit 10 more stable and secure after installation.

[0116] In one example, the two brackets 200 may be independent of each other, and each bears a portion of the weight of the air-conditioning indoor unit 10 .

[0117] In another example, a connecting rail may be provided between the two brackets 200 . The connecting rail may be connected between the fixed rails 210 or the sliding rails 220 of the two brackets 200 , so that the two brackets 200 form a more stable whole.

[0118] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
