Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and more specifically, to an air conditioner housing assembly and an air conditioner. Background Technology

[0002] Existing ceiling-mounted air conditioners embed the main body of a box-type air conditioner, containing a fan and heat exchanger, into the ceiling for fixation. A frame is fixed to the lower side of the air conditioner body facing the room, completely covering the lower side of the main body to conceal internal components. The frame has an air inlet, and an air inlet grille is detachably and rotatably mounted to the frame, completely covering the air inlet. A filter is placed between the air inlet grille and the frame, corresponding to the air inlet, to filter dust and other impurities from the air. The frame and air inlet grille are typically connected and supported by ribs extending parallel to the pivot. This structure has the following disadvantages during installation and use: the rib structure easily leads to uneven stress on the pivot, causing the pivot to bend and deform after long-term use, affecting the opening and closing function and lifespan of the air inlet grille; the structure has poor stability and is prone to loosening or abnormal noise under vibration or external forces. Utility Model Content

[0003] The problem solved by this utility model is that when the existing ceiling-mounted machine frame and air inlet grille are connected by a rib structure, the insufficient support of the rib structure leads to uneven stress on the rotating shaft, which is prone to bending and vibration.

[0004] To address the aforementioned problems, this utility model provides an air conditioner housing assembly. The air conditioner housing assembly is mounted on an air conditioner and connects the front frame and the air inlet grille. The air conditioner housing assembly is fixed to the surface of the front frame by fasteners. A positioning block protrudes from the bottom of the front frame, and the positioning block and the bottom surface of the front frame form a slot. The air conditioner housing assembly includes a sliding shaft, which is rotatably connected to the air inlet grille. One side of the sliding shaft has a sliding portion, which is inserted into the slot in a predetermined direction. Simultaneously, the sliding shaft is inserted into the air inlet grille. The slot supports the sliding portion, thus supporting the sliding shaft. The air inlet grille is mounted on the front frame via the sliding shaft.

[0005] Compared with existing technologies, the technical effects achieved by adopting this solution are as follows: The sliding part is supported by a slot formed by the positioning block at the bottom of the frame and the bottom surface. This optimizes the localized point and line contact support of the existing rib structure into surface contact support, significantly dispersing the force of the air intake grille's weight on the rotating shaft. This effectively prevents the rotating shaft from bending and deforming due to uneven stress, ensuring smooth opening and closing of the air intake grille over the long term and extending the structure's service life. The sliding part's insertion and disengagement from the slot in a preset direction replaces the existing rib structure's connection with the rotating shaft. The adaptive fit between the sliding part and the slot reduces connection gaps and maintains a stable support relationship under vibration or external forces, avoiding the loosening problems caused by widening gaps in the existing rib structure. This effectively suppresses abnormal noises caused by vibration and improves reliability.

[0006] Furthermore, the air conditioner housing assembly also includes: a positioning support, a sliding pivot located on one side of the positioning support, and the positioning support being able to drive the sliding pivot to move synchronously, so that the sliding part can be inserted into or disengaged from the slot.

[0007] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: the sliding pivot and the positioning support are integrally formed, and the positioning support can drive the sliding part to move stably along the preset direction, avoiding the possible offset or tilt when the sliding part moves alone in the prior art, ensuring that the sliding part is accurately inserted into the slot and forms a reliable support, and further ensuring the uniformity of the force on the support structure.

[0008] Furthermore, the surface of the positioning support is provided with a groove, and the fastener is set in the groove. The end of the fastener away from the positioning support is fixedly connected to the bottom surface of the face frame. The length direction of the groove is consistent with the direction of the sliding part inserting into the slot. When the sliding part is inserted into the slot, one end of the groove along the length direction abuts against the fastener. When the sliding part is disengaged from the slot, the other end of the groove along its length direction abuts against the fastener.

[0009] Compared with existing technologies, the technical effects achieved by adopting this solution are as follows: Through the cooperation of the slide and fastener, the movement range of the positioning support is strictly limited within the length of the slide, and the direction of the slide is consistent with the direction in which the sliding part inserts into the slot. This avoids the sliding part failing to accurately insert into the slot due to excessive movement or deviation from the preset direction of the positioning support, solving the assembly misalignment problem that easily occurs in existing technologies lacking directional limiting structures, and ensuring the fitting accuracy between the sliding part and the slot. Compared with existing technologies that rely on multiple sets of protrusions, grooves, and other hard limiting mechanisms, the cooperation between the slide and fastener does not require additional force to break through the limits; the range constraint is naturally achieved simply by the support sliding along the slide.

[0010] Furthermore, the sliding part is located on the side of the positioning support facing the positioning block, and is inserted into or disengaged from the slot synchronously with the movement of the positioning support.

[0011] Compared with existing technologies, the technical effects achieved by adopting this solution are as follows: The sliding part is fixed to the side of the positioning support facing the positioning block, and its movement direction is completely synchronized with the positioning support, always facing the slot direction. This avoids the problem of the sliding part deviating from the slot that may occur when the sliding part and the positioning support move independently in existing technologies, ensuring that the sliding part can be accurately inserted into the slot in one go, reducing the assembly error rate. The fixed connection between the sliding part and the positioning support allows the weight of the air intake grille borne by the sliding part to be directly transferred to the positioning support, and then distributed to the face frame through the cooperation between the positioning support and the face frame (sliding groove + fasteners). This avoids the local stress concentration caused by the sliding part being subjected to force alone in existing technologies, further preventing the sliding part or the rotating shaft from bending, and improving the overall structural load-bearing reliability.

[0012] Furthermore, the end of the sliding pivot component away from the sliding part is provided with a rotating shaft, and the air inlet grille is provided with a positioning hole; the rotating shaft can be inserted into the positioning hole as the positioning support component moves, and the rotating shaft and the positioning hole are rotatably hinged together.

[0013] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: the rotating shaft is inserted into the positioning hole of the air inlet grille synchronously with the movement of the positioning support, and forms a linkage with the movement of the sliding part into the slot. Only the positioning support needs to be moved to complete the "supporting engagement between the sliding part and the slot" and the "rotatable hinged engagement between the rotating shaft and the positioning hole" at the same time, which replaces the step-by-step operation of aligning the support structure and the rotating shaft separately in the existing technology. It is suitable for the narrow installation space of ceiling-mounted machines.

[0014] Furthermore, the positioning support is provided with limiting blocks on both sides, and the bottom surface of the face frame is provided with a snap-fit ​​groove adapted to the positioning support. The edge of the snap-fit ​​groove is provided with a limiting groove that matches the limiting block. The limiting block can snap into or out of the limiting groove as the positioning support moves.

[0015] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: by engaging the limiting block and the limiting groove, the position of the supporting component can be fixed after the positioning support component drives the sliding part to insert into the slot and the rotating shaft to insert into the positioning hole. This avoids the problem that the supporting component is easily slightly displaced due to vibration or external force when relying solely on the sliding groove for limiting in the existing technology, further ensuring the stable cooperation of the structure and reducing the risk of air intake grille displacement.

[0016] Furthermore, the inner side of the limiting block is provided with an elastic element that can deform.

[0017] Compared with existing technologies, the technical effects achieved by adopting this solution are as follows: The elastic element inside the limiting block can drive the limiting block to automatically move closer to or away from the limiting groove through its own deformation, replacing the operation logic of manually prying the limiting block (or overcoming hard friction) to achieve switching in existing technologies. When switching between different limiting grooves is required, only a small external force needs to be applied to push the positioning support, and the elastic element can naturally deform with the movement of the support, causing the limiting block to disengage from the current limiting groove and reset and engage in the new position, greatly reducing the operational intensity, especially suitable for one-handed operation scenarios in the confined installation space of ceiling-mounted machines. In its natural state, the elastic element can apply a continuous preload to the limiting block, making the limiting block fit tightly against the inner wall of the limiting groove, eliminating the fit gap, and ensuring that the limiting block is always reliably engaged with the limiting groove under vibration or external force, further suppressing abnormal noise caused by loosening and improving structural stability.

[0018] Furthermore, the outer side of the positioning block is provided with reinforcing ribs, which extend along the sliding direction of the sliding part; the reinforcing ribs extend from the outer wall of the positioning block to the bottom surface of the face frame.

[0019] Compared with existing technologies, the technical effects achieved by adopting this solution are as follows: The reinforcing ribs on the outer side of the positioning block extend along the sliding direction of the sliding part and extend from the outer wall of the positioning block to the bottom surface of the face frame, forming a triangular support structure of the positioning block, reinforcing ribs, and face frame, which significantly improves the connection strength between the positioning block and the bottom of the face frame. Compared with the existing technology where the positioning block is directly connected to the face frame (without reinforcing ribs), which is prone to tilting or bending due to long-term pressure transmitted by the sliding part, the reinforcing ribs can disperse the stress at the root of the positioning block, prevent the positioning block from deforming and causing changes in the shape of the slot, thereby ensuring that the sliding part can always maintain a suitable and close support relationship with the slot, and maintain stable force transmission.

[0020] Furthermore, the positioning support also includes an auxiliary component, which is disposed on the side of the positioning support away from the sliding part and protrudes from the surface of the positioning support.

[0021] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: For scenarios where the gap between the bottom of the face frame and the ceiling is narrow during the installation of the ceiling machine, the auxiliary component protrudes from the surface of the positioning support component, providing a clear and easy-to-grip force application point, avoiding the problems of finger slippage and force application position deviation. Even with one-handed operation, the positioning support component can be easily pushed to slide along the slide groove, reducing the difficulty of operation.

[0022] To address the aforementioned problems, this utility model provides an air conditioner, including the air conditioner housing assembly provided by the above-mentioned technical features. The air conditioner includes: a front frame and an air inlet grille, the front frame and the air inlet grille being detachably connected via the air conditioner housing assembly; the air conditioner housing assembly is fixed to the surface of the front frame by fasteners; the air conditioner housing assembly includes a sliding pivot, and the air inlet grille is mounted on the front frame via the sliding pivot.

[0023] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: By using designs such as "slot and sliding surface contact support" and "positioning block reinforcing ribs" in the air conditioner housing assembly, the easily failed rib structure in the existing technology is replaced. This allows the connection between the face frame and the air intake grille to evenly distribute the weight and vibration load of the grille, avoiding problems such as shaft bending and positioning block deformation caused by localized stress concentration. This improves the wear resistance of the entire air conditioner structure from the core connection link, reduces the risk of failure after long-term use, and extends the service life of the entire unit.

[0024] In summary, the above-mentioned technical solutions of this application can have one or more of the following advantages or beneficial effects: i) The surface contact support between the slot and the sliding part disperses the bearing force, avoiding the bending of the shaft caused by the existing rib structure; the reinforcing ribs on the outside of the positioning block strengthen the connection strength between the face frame and the positioning block, preventing the positioning block from deforming; the pre-tightening limit block of the elastic element eliminates the fit gap, reduces the risk of vibration and loosening, and improves the structural wear resistance from multiple aspects such as support, load-bearing, and locking, indirectly extending the service life of the air conditioner. ii) Relying on the positioning support, the sliding part and the rotating shaft are synchronously assembled without the need for step-by-step alignment; the force application point of the auxiliary part is adapted to the narrow installation space, solving the problem of inconvenient operation. iii) The close fit between the sliding part and the slot and the pre-tightening effect of the elastic element help to eliminate the connection gap and suppress vibration and abnormal noise; the precise fit between the rotating shaft and the positioning hole ensures smooth opening and closing of the air intake grille without offset or jamming, making the air conditioner operate more quietly and improving user comfort.

Detailed Implementation

[0027] The purpose of this utility model is to provide an air conditioner housing assembly to achieve the desired effect.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] See Figures 1-8 This utility model provides an air conditioner housing assembly 1, which is disposed on an air conditioner and is used to connect the front frame 2 and the air inlet grille 3. The air conditioner housing assembly 1 is fixed to the surface of the front frame 2 by fasteners 132. A positioning block 21 is provided on the bottom of the front frame 2, and the positioning block 21 and the bottom surface of the front frame 2 are spaced apart to form a slot 22. The air conditioner housing assembly includes a sliding pivot 11, which is rotatably connected to the air inlet grille 3. A sliding part 12 is provided on one side of the sliding pivot 11. The sliding part 12 is inserted into the slot 22 in a preset direction. At the same time, the sliding pivot 11 is inserted into the air inlet grille 3. The sliding part 12 is supported by the slot 22 to support the sliding pivot 11. The air inlet grille 3 is mounted on the front frame 2 by the sliding pivot 11.

[0030] Specifically, an air conditioning housing assembly is provided on the edge of the bottom frame 2 of the ceiling unit to mount the air intake grille 3 on the bottom surface of the frame 2. The air conditioning housing assembly is fixed to the lower surface of the frame by fasteners. A positioning block 21 protrudes from the bottom of the frame 2, and the positioning block 21 is spaced from the bottom surface of the frame 2 to form a slot 22. The sliding pivot 11 is detachably connected to the air intake grille 3; the sliding part 12 is arranged in the same row as the sliding pivot 11. When the air intake grille 3 is installed at the bottom of the frame 2, the positioning support 13 slides toward the side with the positioning block 21, the sliding part 12 inserts into the slot 22, and the sliding pivot 11 moves synchronously to insert into the air intake grille 3. In the prior art, the rib structure and the pivot are in point or line contact, and the weight of the air intake grille 3 is concentrated at a few contact points, causing local overload on the pivot and making it prone to bending deformation. The concentrated load is distributed to the entire contact area between the sliding part 12 and the slot 22. The sliding shaft 11 only bears the axial force along its own axis and is no longer subjected to bending moment, thus completely solving the bending problem caused by the concentrated force on the shaft.

[0031] See Figures 3-6The air conditioner housing assembly also includes: a positioning support 13, a sliding pivot 11 located on one side of the positioning support 13, and the positioning support 13 can drive the sliding pivot 11 to move synchronously, so that the sliding part 12 can be inserted into or disengaged from the slot 22.

[0032] Specifically, the sliding pivot 11, the sliding part 12, and the positioning support 13 are integrally formed. The sliding pivot 11 is located on the side of the positioning support 13 close to the sliding part. When the positioning support 13 slides, it drives the sliding part 12 to insert into the slot 22. With the support of the slot 22 on the sliding part 12, the sliding pivot 11 is supported.

[0033] See Figures 3-6 The surface of the positioning support 13 is provided with a groove 131, and the fastener 132 is disposed in the groove 131. The end of the fastener 132 away from the positioning support 13 is fixedly connected to the bottom surface of the face frame 2. The length direction of the groove 131 is consistent with the direction in which the sliding part 12 is inserted into the slot 22. When the sliding part 12 is inserted into the slot 22, one end of the groove 131 along the length direction abuts against the fastener 132. When the sliding part 12 is disengaged from the slot 22, the other end of the groove 131 along its length direction abuts against the fastener 132.

[0034] Specifically, the positioning support 13 uses a groove 131 on its surface to engage with a fastener 132. The fastener 132 passes through the groove 131 and is fixed to the bottom surface of the frame 2, thus limiting the range of movement of the positioning support 13. The directional constraint of the groove 131 and the fastener 132 ensures that the support moves in the neutral direction and limits lateral swaying during vibration, maintaining a stable fit clearance.

[0035] See Figures 5-8 The sliding part 12 is located on the side of the positioning support 13 facing the positioning block 21, and is inserted into or disengaged from the slot 22 synchronously with the movement of the positioning support 13.

[0036] Specifically, the positioning support 13 slides towards the positioning block 21, causing the sliding part 12 to move synchronously and insert into the slot 22; the positioning support 13 slides in the opposite direction to the positioning block 21, causing the sliding part 12 to move synchronously and disengage from the slot 22.

[0037] See Figures 5-8 The sliding pivot 11 has a rotating shaft 111 at one end away from the sliding part 12, and the air inlet grille 3 has a positioning hole 31. The rotating shaft 111 can be inserted into the positioning hole 31 as the positioning support 13 moves, and the rotating shaft 111 and the positioning hole 31 are rotatably hinged together.

[0038] Specifically, one end of the sliding pivot 11 is provided with a rotating shaft 111, which is inserted into the positioning hole 31 of the air inlet grille 3, so that the air inlet grille 3 can rotate around the rotating shaft 111, thereby realizing the opening and closing of the air inlet grille 3 on the surface of the face frame 2.

[0039] See Figures 3-6 The positioning support 13 has limiting blocks 133 on both sides, and the bottom surface of the face frame 2 has a snap-fit ​​groove 23 adapted to the positioning support 13. The edge of the snap-fit ​​groove 23 has a limiting groove 231 that matches the limiting block 133. The limiting block 133 can be snapped into or out of the limiting groove 231 as the positioning support 13 moves.

[0040] The inner side of the limiting block 133 is provided with an elastic element 134, which can deform.

[0041] Specifically, the limiting blocks 133 on both sides of the positioning support 13 cooperate with the limiting grooves 231 provided on the edge of the bottom surface locking groove 23 of the face frame 2; the elastic element 134 inside the limiting block 133 can deform, driving the limiting block 133 to elastically engage or disengage from the limiting groove 231, thereby achieving position locking and unlocking, and facilitating the switching of the limiting block 133 between different limiting grooves 231.

[0042] The outer side of the positioning block 21 is provided with a reinforcing rib 211, which extends along the sliding direction of the sliding part 12; the reinforcing rib 211 extends from the outer wall of the positioning block 21 to the bottom surface of the face frame 2.

[0043] Specifically, the reinforcing ribs 211 on the outer side of the positioning block 21 extend from the outer wall of the positioning block 21 to the bottom surface of the face frame 2.

[0044] See Figure 3 and Figure 4 The positioning support 13 also includes an auxiliary member 135, which is disposed on the side of the positioning support 13 away from the sliding part 12 and protrudes from the surface of the positioning support 13.

[0045] Specifically, the auxiliary component 135 protrudes from the surface of the positioning support component 13, providing a force point for pushing the positioning support component 13 to slide, which facilitates operation in a confined space.

[0046] This utility model provides an air conditioner, including the air conditioner housing assembly provided by the above-mentioned technical features. The air conditioner includes: a front frame 2 and an air inlet grille 3. The front frame 2 and the air inlet grille 3 are detachably connected by the air conditioner housing assembly. The air conditioner housing assembly 1 is fixed to the surface of the front frame 2 by fasteners 132. The air conditioner housing assembly 1 includes a sliding pivot 11, and the air inlet grille 3 is mounted on the front frame 2 by the sliding pivot 11.

[0047] Specifically, the air intake grille 3 is fixed to the bottom of the face frame 2 by the air conditioner housing assembly, and the air intake grille 3 can rotate about the rotation shaft 111 on the sliding pivot 11 as the rotation center. The air conditioner housing assembly 1 is fixed to the bottom surface of the face frame 2 by fasteners 132; the air intake grille 3 is installed on the air conditioner housing assembly 1 by hinged engagement with the sliding pivot 11.

[0048] Preferably, the air conditioning housing components on both sides of the face frame simultaneously position the air intake grille, and the sliding pivots on both sides are respectively inserted into the corresponding positioning holes to realize the air intake grille being installed on the bottom surface of the face frame. The positioning holes of the air intake grille are hinged to the sliding pivots, so that the air intake grille can open and close on the face frame.

[0049] In this design, the air conditioner housing assembly 1 is located at both ends of the bottom of the face frame 2. During installation, the positioning support 13 is initially installed in the snap-fit ​​groove 23 of the face frame 2 using fasteners 132. The auxiliary component 135 is pushed so that the sliding part 12 is inserted into the slot 22 and the rotating part is inserted into the positioning hole 31 of the air inlet grille 3. At this time, the limiting block 133 is locked into the limiting groove 231 under the action of the elastic component 134, completing the position locking. Finally, the fasteners 132 are tightened to fix it. During disassembly, the limiting block 133 is pressed to compress the elastic component 134 and disengage it from the limiting groove 231. After loosening the fasteners 132, the auxiliary component 135 is pushed in the opposite direction, causing the sliding part 12 to disengage from the slot 22 and the rotating shaft 111 to be pulled out from the positioning hole 31 on the air inlet grille 3, thereby realizing the separation of the air inlet grille 3 from the face frame 2.

[0050] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
