Description

Technical Field

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

[0002] In air conditioning equipment, the air outlet frame is an important component for guiding airflow, and its fixation reliability directly affects the performance of the air conditioner and the user experience. To enhance the fixation reliability of the air outlet frame, screw positions are usually provided at the bottom of the air outlet frame, and it is fixed to the unit body by screw connection.

[0003] For fresh air cabinet air conditioners, their structure is more complex than that of traditional air conditioners. At the bottom of the air outlet frame, the upper part is often the air duct of the cross-flow fan, which is used to transport and circulate air; the lower part is the fresh air module, which is responsible for introducing and treating outdoor fresh air. This structural layout results in very limited installation space at the bottom of the air outlet frame.

[0004] Furthermore, the air vent frame is usually part of the front panel assembly. During the air conditioner assembly process, the front panel assembly needs to be lifted upwards as a whole in order to be assembled and fixed with other components. This requires leaving sufficient clearance for the lifting stroke, which further limits the design space of the bottom fixing structure of the air vent frame.

[0005] Therefore, given the limited space at the bottom of the air outlet frame, designing an assembly structure that can both meet the clearance required for the overall lifting of the front panel assembly and ensure the reliability of the air outlet frame's fixation has become a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] Addressing the technical problem of low reliability of air outlet frame fixing in existing fresh air cabinet air conditioners, this utility model provides an air conditioner cabinet unit that uses a stepped cantilever fixing part at the bottom of the air outlet frame. This not only meets the clearance required for the overall lifting of the front panel assembly but also ensures the reliability of the air outlet frame fixing.

[0007] This utility model provides an air conditioner cabinet unit, including:

[0008] Air intake grille assembly;

[0009] Front panel assembly, including connected panel frame and air outlet frame;

[0010] The panel frame has an air outlet, and multiple hooks are spaced apart along the vertical direction on its left and right sides; the air inlet grille assembly has a hanging groove corresponding to the hooks.

[0011] The air outlet frame is correspondingly disposed inside the air outlet of the panel frame, and is detachably connected to the panel frame by a buckle structure and fixed by fasteners;

[0012] The bottom of the air outlet frame extends to form a cantilever fixing part that protrudes towards the rear side of the panel frame. The cantilever fixing part has a stepped structure, and the width of the end connected to the air outlet frame is greater than the width of the free end.

[0013] At least one hook of the panel frame is provided with a receiving part that cooperates with the cantilever fixing part. The free end of the cantilever fixing part is provided with a mounting hole and is connected to the receiving part by a fastener.

[0014] In some embodiments, the panel frame includes a front frame portion for mounting a front panel and side plate portions extending rearward along both sides of the front frame portion, wherein the hook is disposed on the side plate portions and extends rearward from the side plate portions.

[0015] In some embodiments, the snap-fit ​​structure includes:

[0016] Multiple claws are spaced apart along the vertical direction on the rear side of one side of the front frame.

[0017] Multiple slots are provided on one side of the air outlet frame, corresponding to the claws.

[0018] In some embodiments, a positioning groove is provided on one side of the air outlet frame opposite to the slot, and a first positioning part is provided on the side plate corresponding to the positioning groove. The first positioning part cooperates with the positioning groove to restrict the air outlet frame from moving upward and / or downward.

[0019] In some embodiments, the front frame portion is further provided with a second positioning portion near the claw, and the second positioning portion also cooperates with the slot to limit the displacement of the air outlet frame in the left and right directions.

[0020] In some embodiments, the cantilever fixing part includes:

[0021] The cantilever root is formed by multiple horizontal reinforcing ribs arranged vertically and vertically.

[0022] An extension fixing part is formed by extending outward along the lower part of the cantilever root, and the mounting hole is provided at one end of the extension fixing part.

[0023] In some embodiments, longitudinal support ribs are provided between the transverse reinforcing ribs.

[0024] In some embodiments, the extended fixing portion is arranged at an angle to the vertical connecting stiffener.

[0025] In some embodiments, the mounting hole is an elliptical hole.

[0026] In some embodiments, the system further includes a base, on which the air intake grille assembly and the front panel assembly are disposed. The bottom of the panel frame is provided with a downwardly protruding insertion portion, and the base is provided with an insertion groove corresponding to the insertion portion.

[0027] Compared with the prior art, the advantages and positive effects of this utility model are:

[0028] The aforementioned air conditioner unit features a stepped cantilever mounting section at the bottom of the air outlet frame. The free end of this cantilever mounting section has a smaller width, effectively avoiding components such as the fan located above the air outlet frame when the front panel assembly is lifted for assembly. This provides ample clearance for the lifting of the front panel assembly, significantly improving assembly convenience and smoothness. Simultaneously, the connecting end of the cantilever mounting section has a larger width. This stepped structure effectively transfers and distributes the stress borne by the screw fixing point under stress or harsh experimental conditions to the wider area of ​​the connecting end, ensuring the reliability of the air outlet frame fixation.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0051] Reference Figures 1-8 This is one embodiment of the air conditioner cabinet unit of this utility model.

[0052] The air conditioner unit includes a base 100, an air intake grille assembly 200 disposed on the base 100, and a front panel assembly 300.

[0053] Air intake grille assembly 200 is used to guide air into the air conditioner.

[0054] Front panel assembly 300, such as Figure 3 As shown, it includes a panel frame 310, an air outlet frame 320, and a front panel (not shown).

[0055] The panel frame 310 has an air outlet 312. The inner side of the upper part of the air outlet 312 is the air duct of the cross-flow fan. The lower part is the fresh air outlet area, and a fresh air module is installed on the inner side.

[0056] Multiple hooks 315 are provided at intervals along the vertical direction on the left and right sides of the panel frame 310; a hanging groove is provided on the air inlet grille assembly 200 corresponding to the hooks 315; the panel frame 310 is hung in the hanging groove of the air inlet grille assembly 200 through the hooks 315.

[0057] The front panel is fixed to the front side of the panel frame 310 by means of screws or clips, forming the exterior surface of the air conditioner.

[0058] The air outlet frame 320 is disposed inside the air outlet 312 of the panel frame 310, and is typically used to install an air guide plate (not shown) to adjust the air outlet direction. The air outlet frame 320 is detachably connected to the panel frame 310 by a snap-fit ​​structure and is finally fixed by fasteners.

[0059] In particular, such as Figure 3and Figure 5 As shown, the bottom of the air outlet frame 320 extends to form a cantilever fixing part 321 that protrudes towards the rear side of the panel frame 310. The cantilever fixing part 321 has a stepped structure, and the width of the end connected to the air outlet frame 320 is greater than the width of the free end.

[0060] At least one hook 315 of the panel frame 310 is provided with a receiving part 316 that cooperates with the cantilever fixing part 321. The free end of the cantilever fixing part 321 is provided with a mounting hole 3125 and is connected to the receiving part 316 by fasteners (such as screws) to achieve reliable fixation of the bottom of the air outlet frame 320.

[0061] The aforementioned air conditioner unit, by incorporating a stepped cantilever fixing part 321 at the bottom of the air outlet frame 320, features a smaller width at the free end of the cantilever fixing part 321. This allows for effective avoidance of components such as the fan located above the air outlet frame 320 during assembly when the front panel assembly 300 is lifted upwards, thus providing ample travel clearance for the overall lifting of the front panel assembly 300 and significantly improving assembly convenience and smoothness. Simultaneously, the larger width of the connecting end of the cantilever fixing part 321, with its stepped structure, effectively transfers and distributes the stress borne by the screw fixing point under stress or harsh experimental conditions to the wider area of ​​the connecting end, ensuring the reliability of the air outlet frame 320's fixation.

[0062] In some embodiments of this application, such as Figure 3 As shown, the panel frame 310 includes a front frame portion 311 and a side panel portion 314.

[0063] The front frame 311 is used to mount the front panel, forming the front profile of the air conditioner.

[0064] The side panel portion 314 extends rearward along the left and right edges of the front frame portion 311, forming the side wall of the panel frame 310. The hook 315 is provided on the inner side of the side panel portion 314 and extends rearward from the side panel portion 314 so as to cooperate with the hanging groove on the air intake grille assembly 200 to achieve the initial positioning and suspension of the front panel assembly 300.

[0065] In some embodiments of this application, such as Figure 6 As shown, the snap-fit ​​structure includes multiple claws 313 and multiple slots 322.

[0066] Multiple claws 313 are spaced apart along the vertical direction on the rear side of one side of the front frame 311; multiple slots 322 are correspondingly arranged with the multiple claws 313 on one side of the air outlet frame 320.

[0067] When the air outlet frame 320 is installed into the air outlet 312 of the panel frame 310, the claw 313 can be engaged into the slot 322, thereby achieving the initial fixation and connection between the air outlet frame 320 and the panel frame 310.

[0068] In some embodiments of this application, such as Figure 7 As shown, to further improve the positioning accuracy and stability of the air outlet frame 320, a positioning groove 323 is provided on one side of the air outlet frame 320 opposite to the slot 322, and a first positioning part 317 is provided on the side plate portion 314 of the panel frame 310 corresponding to the positioning groove 323. The first positioning part 317 cooperates with the positioning groove 323 to effectively restrict the movement of the air outlet frame 320 in the vertical direction (upward and / or downward), preventing it from shaking or misaligning during assembly.

[0069] In some embodiments of this application, in order to more comprehensively limit the displacement of the air outlet frame 320, such as Figure 6 As shown, a second positioning part 318 is also provided on the front frame 311 near the claw 313. This second positioning part 318 can simultaneously cooperate with the slot 322 on the air outlet frame 320. Through this cooperation, the displacement of the air outlet frame 320 in the horizontal direction (left and right direction) can be effectively restricted, ensuring the stability and accuracy of the air outlet frame 320 in the panel frame 310.

[0070] Through the engagement of the claw 313 and the slot 322, the cooperation of the first positioning part 317 and the positioning groove 323, and the synergistic effect of the second positioning part 318 and the slot 322, a stable and detachable connection between the air outlet frame 320 and the panel frame 310 can be achieved, which not only facilitates assembly and maintenance, but also ensures the reliability of the air outlet frame 320 during use.

[0071] Furthermore, multiple screw fixing structures are provided between the air outlet frame 320 and the panel frame 310, which further ensures a stable fixation between the air outlet frame 320 and the panel frame 310.

[0072] In some embodiments of this application, the cantilever fixing part 321 includes a cantilever root and an extension fixing part 3214.

[0073] The cantilever root is the main structure connecting the cantilever fixing part 321 and the air outlet frame 320, and its strength directly affects the reliability of the fixing. For example... Figure 5 As shown, the cantilever root is composed of multiple horizontal reinforcing ribs 3211 arranged vertically and connected by vertical connecting ribs 3212. The horizontal reinforcing ribs 3211 provide the main supporting strength and resist bending deformation; the vertical connecting ribs 3212 are used to connect the various horizontal reinforcing ribs 3211 to form a stable overall structure.

[0074] The extension fixing part 3214 extends outward from the lower part of the cantilever root and its main function is to provide an area for connection with the receiving part 316 of the panel frame 310. The mounting hole 3125 is provided at the free end of the extension fixing part 3214 for accommodating fasteners (such as screws) to achieve a fixed connection with the panel frame 310.

[0075] In some embodiments of this application, in order to further improve the structural strength and stability of the cantilever root, longitudinal support ribs 3213 are also provided between the transverse stiffening ribs 3211. The longitudinal support ribs 3213 can connect the upper and lower adjacent transverse stiffening ribs 3211 to form a mesh reinforcement structure, effectively dispersing stress and improving the overall bending and torsional resistance of the cantilever root.

[0076] In some embodiments of this application, the extended fixing part 3214 is set at a certain angle to the vertical connecting stiffener 3212 in the horizontal plane, which helps to better align with the receiving part 316 of the panel frame 310 during assembly.

[0077] In some embodiments of this application, the mounting hole 3125 is an elliptical hole, and the major axis of the elliptical hole is set along the vertical direction. Using an elliptical hole can provide a certain assembly adjustment margin, allowing for fine adjustment of the position of the air outlet frame 320 in the vertical direction, thereby compensating for dimensional deviations during manufacturing or assembly, making the installation of fasteners smoother, and avoiding stress concentration caused by hole position deviations.

[0078] In some embodiments of this application, to facilitate the initial installation of the front panel assembly 300, such as... Figure 3 The bottom of the panel frame 310 is provided with a downwardly protruding insertion part 319, and the base 100 is provided with an insertion groove corresponding to the insertion part 319. This insertion structure can provide an initial positioning point and support for the installation of the front panel assembly 300.

[0079] The assembly process for front panel assembly 300 is as follows:

[0080] (1) Preliminary positioning: such as Figure 8 Tilt the front panel assembly 300 at a certain angle so that the bottom plug-in part 319 is aligned and inserted into the corresponding plug-in slot on the base 100. With the cooperation of the plug-in part 319, the front panel assembly 300 can be initially fixed on the base 100 and obtain a certain support.

[0081] (2) Rotation and approach: Using the bottom insertion part 319 as a fulcrum, rotate the front panel assembly 300 to gradually bring it closer to a vertical state. During this process, the hooks 315 located on the side panel part 314 of the panel frame 310 have not yet been fastened into the corresponding hook slots on the air intake grille assembly 200 because the front panel assembly 300 is still in an inclined state.

[0082] (3) Alignment and attachment: After the front panel assembly 300 is nearly vertical, the operator lifts the front panel assembly 300 upwards. By lifting, the hooks 315 on the side panel 314 of the panel frame 310 can be accurately aligned with the hanging slots on the air intake grille assembly 200.

[0083] (4) Assembly completion: After the hook 315 is aligned with the slot, the operator lowers the front panel assembly 300 downwards. Under the action of gravity, the hook 315 on the panel frame 310 is successfully engaged in the slot of the air intake grille assembly 200, realizing a reliable connection between the front panel assembly 300 and the air intake grille assembly 200. At this point, the assembly process of the front panel assembly 300 is completed.

[0084] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
