[0042] In existing technologies, split-type air conditioners that facilitate individual installation by users employ flexible refrigerant pipes to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. Thus, when users install the equipment themselves, they only need to fix the indoor and outdoor units separately, without needing to install refrigerant pipes or add refrigerant, thereby reducing installation difficulty and enabling individual installation.

[0043] Mounting brackets for air conditioner outdoor units typically consist of a main bracket and a support bracket. One end of the main bracket is mounted to the window frame, and the other end extends outside the window to support the outdoor unit. One end of the support bracket is connected to the main bracket, and the other end rests against the exterior wall. However, existing support brackets are not convenient to install when moved on the main bracket for position adjustment.

[0044] To solve this technical problem, this utility model proposes a mounting bracket for installing an outdoor unit 52 of an air conditioner.

[0045] Please see Figures 1 to 8 In one embodiment of this utility model, the mounting bracket includes a main bracket 10, a support bracket 20, and a limiting member 30. The main bracket 10 includes a window mounting bracket 11 and a load-bearing bracket 12. The window mounting bracket 11 can be installed on the window frame. The load-bearing bracket 12 is connected to the window mounting bracket 11 and extends outside the window. The lower surface of the load-bearing bracket 12 is provided with a guide groove 121. The bottom wall of the guide groove 121 is provided with a plurality of limiting holes 122 along its extension direction. The outdoor unit 52 of the air conditioner is located on the upper side of the load-bearing bracket 12. The upper end of the support bracket 20 is slidably installed in the guide groove 121, and the lower end is used to abut against the exterior wall and / or window sill. The limiting member 30 is elastically connected to the support bracket 20 and can be locked in any of the limiting holes 122. This improves the ease of installation of the support bracket 20 and the main bracket 10.

[0046] In the technical solution of this utility model, the upper end of the support bracket 20 is adjusted within the guide groove 121 by sliding cooperation between the support bracket 20 and the guide groove 121, so that the mounting bracket can adapt to window sills of different widths. After the support bracket 20 is moved into place, the limiting member 30 can be elastically locked into the limiting hole 122 on the bottom wall of the guide groove 121, so as to achieve relative fixation between the support bracket 20 and the load-bearing bracket 12. Thus, through the cooperation of the limiting member 30 and the limiting hole 122, the installation and fixation of the support bracket 20 and the main bracket 10 do not require the use of screws and corresponding screwdrivers, which helps to improve the ease of installation of the support bracket 20 and the main bracket 10, thereby improving the user experience.

[0047] It should be noted that in this embodiment of the application, the inner side of the window is defined as the rear and the outer side of the window is defined as the front. Therefore, the arrangement direction of each limiting hole 122 and the extension direction of the guide groove 121 are both the front and back directions. The upper side of the outdoor unit 52 is the top and the lower side of the outdoor unit 52 is the bottom.

[0048] Specifically, the bottom wall of the guide groove 121 is provided with multiple limiting holes 122, which can fix the support bracket 20 relatively at a certain position on the load-bearing bracket 12. Furthermore, by selectively engaging the limiting member 30 with one of the multiple limiting holes 122, the relative position of the support bracket 20 on the load-bearing bracket 12 can be adjusted, thereby enabling the mounting bracket to adapt to window sills of different widths.

[0049] The guide groove 121 penetrates the end face of the load-bearing bracket 12 and forms an installation opening. The mounting bracket also includes a cover that seals the installation opening. Specifically, the upper end of the support bracket 20 is inserted into the guide groove 121 from the end of the load-bearing bracket 121 with the installation opening, and the cover prevents the support bracket 20 from detaching from the installation opening. The cover can be fixed to the load-bearing platform by adhesive, snap-fit, or other methods. In this case, the limiting hole 122 can be configured as a hole structure of any shape, such as a round hole or a square hole. Alternatively, in other embodiments, the limiting hole 122 is provided on at least one of the two opposing side walls of the guide groove 121. Or, the guide groove 121 may not have an installation opening.

[0050] Please see Figure 4 In this embodiment of the invention, the upper surface of the load-bearing bracket 12 is provided with a downwardly recessed portion 123, and the limiting hole 122 penetrates the bottom wall of the recessed portion 123. This arrangement effectively reduces the possibility of interference between the limiting member 30 extending out of the limiting hole 122 and the outdoor unit 52 of the air conditioner, while also concealing the limiting member 30. Furthermore, the downwardly recessed portion 123 can, to a certain extent, enhance the structural strength of the main bracket 10, extend the service life of the main bracket 10, and enhance the support effect on the outdoor unit 52 of the air conditioner. Of course, in other embodiments, when the limiting hole 122 is provided on the side wall of the guide groove 121, the outer surface of the side wall may not have a recessed portion 123.

[0051] Please see Figures 5 to 8In this embodiment of the present invention, the support bracket 20 is provided with a receiving groove 21, which extends into the guide groove 121 and houses the limiting member 30. It is understood that the receiving groove 21 on the support bracket 20 can reduce the weight of the support bracket 20 while ensuring its supporting effect, and the receiving groove 21 can protect the limiting member 30. The upper end of the receiving groove 21 has an opening facing the limiting hole 122, which allows the limiting member 30 to extend out and engage with the limiting hole 122, thus achieving the installation and fixation of the support bracket 20 and the main bracket 10. The opening can be formed by the receiving groove 21 penetrating through the upper end face of the support bracket 20, or the opening can be formed on the upper groove wall of the receiving groove 21. This effectively ensures the local structural strength of the upper end of the receiving groove 21.

[0052] Please see Figures 5 to 8 In this embodiment of the present invention, the inner wall of the receiving groove 21 is provided with a limiting flange 22, and a spring 41 is connected between the limiting member 30 and the limiting flange 22. This allows the limiting member 30 to be installed on the support bracket 20, and also facilitates the limiting member 30 to obtain a retaining force through the spring 41 to be locked in the limiting hole 122, thereby ensuring the reliability of the support bracket 20's installation and fixation on the load-bearing bracket 12. The connection methods between the spring 41 and the limiting member 30 and the limiting flange 22 include, but are not limited to, bonding, welding, and snap-fitting.

[0053] Specifically, before installing the outdoor unit 52 of the air conditioner, the user needs to first assemble the mounting bracket on the outside of the window 51. For example, first extend the entire mounting bracket out of the window 51, then install the window mounting bracket 11 on the window frame of the window 51, and then adjust the position of the support bracket 20 on the load-bearing bracket 12 so that the lower end of the support bracket 20 can abut against the outer wall surface below the window 51, and keep the load-bearing bracket 12 in a horizontal or approximately horizontal position so that the outdoor unit 52 of the air conditioner can be stably placed on the load-bearing bracket 12. At the same time, when the load-bearing bracket 12 is kept in a horizontal or approximately horizontal position, due to the removal of external force (such as the pressure from the user's finger), under the elastic reset action of the spring 41, the limiting member 30 moves upward and extends into the limiting hole 122, and under the action of the spring 41, it moves upward. Figure 4 The limiting member 30 is always locked in the limiting hole 122, thus fixing the support bracket 20 on the load-bearing bracket 12. When the limiting member 30 is driven by an external force to move toward the limiting flange 22, the spring 41 is compressed, and the limiting member 30 gradually disengages from the limiting hole 122. Therefore, after the limiting member 30 disengages from the limiting hole 122, the limiting member 30 does not interfere with the load-bearing bracket 12 when the support bracket 20 slides relative to the load-bearing bracket 12.

[0054] Please see Figure 6In this embodiment of the present invention, the inner wall of the receiving groove 21 is provided with a through hole 211. The limiting flange 22 includes a first segment 221 and a second segment 222. The first segment 221 extends from the edge of the through hole 211 toward the center of the through hole 211. The second segment 222 is bent from the side edge of the first segment 221 toward the opening of the receiving groove 21. The limiting member 30 is connected to the second segment 222 by the spring 41. Thus, compared with directly protruding the limiting flange 22 on the inner wall of the receiving groove 21, the limiting flange 22 is formed by bending the material of the support bracket 20 itself, avoiding the weakness points introduced by welding or riveting. This makes the overall structure of the support bracket 20 more coherent, and its structure is simple and easy to implement. At the same time, it helps to reduce redundant weight and reduce processing costs. The second segment 222 of the limiting flange 22 can also be directly used as the mounting position of the spring 41, effectively saving additional positioning steps. In addition, the through hole 211 plays a role in weight reduction. Of course, in other embodiments, the inner wall of the receiving groove 21 is connected with a connecting protrusion extending toward the opening of the receiving groove 21.

[0055] Please see Figures 7 to 8 In this embodiment of the present invention, the spring 41 is provided with a protective cover 42. The protective cover 42 is connected to the inner wall of the receiving groove 21 and also to the limiting flange 22. In this way, the protective cover 42, the inner wall of the receiving groove 21, and the limiting flange 22 form a relatively sealed space, which can effectively limit the deformation path of the spring 41, reduce the risk of the spring 41 disengaging from the limiting member 30 due to deformation, and the limiting member 30 shifting, and ensure the reliable movement of the limiting member 30 and the limiting effect of the limiting member 30 and the limiting hole 122.

[0056] The protective cover 42 is fixed to the support bracket 20 by spot welding. Of course, in other embodiments, the connection method between the protective cover 42 and the support bracket 20 includes, but is not limited to, adhesive bonding, screw connection, and snap-fit ​​connection. For example... Figure 8 As shown, the protective cover 42 includes a cover body, in which a receiving groove is formed to accommodate the spring 41 and the limiting member 30. The opening of the receiving groove is bent with a connecting edge towards the side wall of the receiving groove. The protective cover 42 is connected to the support bracket 20 through the connecting edge, so as to improve the connection strength and connection convenience between the protective cover 42 and the support bracket 20 by increasing the effective connection area between the protective cover 42 and the support bracket 20. The limiting flange 22 forms one side wall of the receiving groove, and the upper wall of the receiving groove, that is, the side wall opposite to the limiting flange 22, is provided with a clearance hole for the limiting member 30 and the spring 41 to pass through.

[0057] Please see Figure 6In an embodiment of this utility model, the limiting member 30 includes a column 31 and a limiting ring 32 protruding from the outer circumferential surface of the column 31. One end of the column 31 can extend into the limiting hole 122, and the other end is fitted with the spring 41. The two ends of the spring 41 are respectively connected to the limiting ring 32 and the limiting flange 22. This arrangement facilitates the connection between the spring 41 and the limiting member 30 and the limiting flange 22, without requiring further processing of the inside of the column 31, thus simplifying the structure of the limiting member 30. Of course, in other embodiments, the end of the column 31 facing the limiting flange 22 has a limiting cavity, one end of the spring 41 is connected to the limiting cavity, and the other end is connected to the limiting flange 22.

[0058] Furthermore, in this embodiment of the invention, with the spring 41 sleeved outside the column 31, the limiting ring 32 is located outside the protective cover 42. This provides a mounting position for the spring 41. In this case, the outer diameter of the spring 41 is smaller than the maximum diameter of the limiting ring 32, allowing the spring 41 to abut against the limiting ring 32. Additionally, when an external force is applied to the limiting member 30, the limiting ring 32 abuts against the protective cover 42, thereby limiting the compression stroke of the spring 41. This reduces the possibility of the spring 41 failing due to excessive compression and the column 31 colliding with the limiting flange 22, thus improving the performance and service life of the spring 41.

[0059] Please see Figure 4 , Figure 6 and Figure 8 In this embodiment of the invention, the end of the column 31 has a guide arc surface 311, which is the end of the column 31 away from the limiting flange 22. Thus, during the process of the end of the column 31 extending into the limiting hole 122, the guide arc surface 311 guides the column 31 smoothly into the limiting hole 122, improving the locking smoothness of the support bracket 20 and the load-bearing bracket 12. Of course, in other embodiments, the end of the column 31 has a guide slope.

[0060] In this embodiment, when the limiting hole 122 is configured as a circular hole, the column 31 can be configured as a cylinder 31, or other columnar structures that can extend into the limiting hole 122. Of course, in other embodiments, the shape of the limiting hole 122 is not limited to circular. The limiting hole 122 can be a through hole structure or a blind hole structure.

[0061] This utility model also proposes an air conditioner, which includes an outdoor unit 52 and a mounting bracket. The specific structure of the mounting bracket is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The mounting bracket is used to install the outdoor unit 52 on the outside of a window.

[0062] Optionally, in an embodiment of this utility model, the air conditioner further includes an indoor unit, which is connected to the outdoor unit 52 via a refrigerant hose assembly, and the refrigerant hose assembly is pre-filled with refrigerant. Specifically, the air conditioner of this utility model can be a split-type air conditioner that is easy for users to install themselves. It uses a flexible refrigerant hose to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit 52, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. In this way, when users install the equipment themselves, they only need to fix the indoor unit and the outdoor unit 52 separately, without assembling the refrigerant hose and adding refrigerant, thereby reducing the installation difficulty and enabling users to install themselves. However, this design is not limited to this. In other embodiments, the air conditioner of this utility model can also be a common split-type air conditioner or an integrated air conditioner, such as a window air conditioner integrated unit, in which case the outdoor unit 52 refers to the part of the window air conditioner that extends to the outside.

[0063] Optionally, in an embodiment of this utility model, the compressor of the air conditioner is located inside the indoor unit of the air conditioner, which can reduce the weight of the outdoor unit 52 of the air conditioner, thereby facilitating the installation of the outdoor unit 52 of the air conditioner; correspondingly, the compressor is also provided with a noise reduction structure to ensure low-noise operation of the indoor unit of the air conditioner.

[0064] Optionally, in an embodiment of this utility model, the bottom of the air conditioner indoor unit is provided with casters to facilitate the movement and transportation of the air conditioner indoor unit; correspondingly, the air conditioner indoor unit is provided with a locking structure to constrain the rotation of the casters, ensuring the stable operation of the air conditioner indoor unit.

[0065] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
