Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air outlet mask structure for air conditioners. Background Technology

[0002] The grille covers of air conditioners on the market are installed on the outdoor unit using multiple screws or a complex snap-fit ​​structure. During maintenance or installation of the internal structure of the outdoor unit, the grille cover needs to be disassembled and reassembled. However, due to the large number of screws or the complexity of the snap-fit ​​structure, the disassembly and reassembly of the grille cover takes a lot of time, causing inconvenience to the work. This not only wastes manpower and time costs, but may also lead to damage to the grille cover in severe cases. Therefore, there is an urgent need for a grille cover structure with a simple snap-fit ​​structure. Utility Model Content

[0003] The purpose of this utility model is to design an air outlet mask structure for air conditioners to overcome the shortcomings of the above-mentioned technologies.

[0004] This utility model designs an air outlet cover structure for an air conditioner, including a housing panel and a grille cover. The housing panel has an air outlet. The grille cover has at least two snap-fit ​​protrusions evenly distributed around its circumferential edge. The bottom end of each snap-fit ​​protrusion is connected to the grille cover, and the top end is bent to one side to form a bent portion. A gap is formed between the bottom surface of the bent portion and the grille cover. The edge of the air outlet has mounting holes that correspond one-to-one with the snap-fit ​​protrusions. Each snap-fit ​​protrusion is inserted into the corresponding mounting hole and moves in the bending direction. The bent portion of each snap-fit ​​protrusion moves to the edge surface of the air outlet on one side of the mounting hole, so that the edge surface of the air outlet at that location is located within the gap. At this time, the snap-fit ​​protrusion is snapped into the mounting hole, thereby realizing the snap-fit ​​connection of the grille cover to the housing panel.

[0005] Preferably, the air outlet edge is bent twice to form an L-shaped mounting groove. The mounting groove includes a horizontal bottom surface and a vertical side surface. The mounting hole is located on the horizontal bottom surface. When the grille cover is snapped onto the housing panel, the edge of the grille cover is embedded in the mounting groove.

[0006] Further optimization involves setting the mounting hole at an angle on one side of the bending section's movement direction to form an inclined surface.

[0007] Preferably, the bottom surface of the bent portion is inclined to form a guide surface, such that the distance between the guide surface and the grid cover gradually increases along the bending direction of the bent portion, and the included angle between the guide surface and the grid cover is α, where α ≥ 5°.

[0008] Further optimization involves the housing panel being a sheet metal part with a thickness of T, and the distance between the root of the guide surface and the grille cover being S, where S≤T+0.3mm.

[0009] Further optimization involves providing circumferentially extending grooves along the edge of the grid cover. When the grid cover is snapped onto the housing panel, the groove opening faces the horizontal bottom surface of the mounting groove. The two horizontal top surfaces where the groove opening is located serve as a first mating surface, approaching or fitting against the horizontal bottom surface of the mounting groove. The outer wall of the groove on the outward side serves as a second mating surface, approaching or fitting against the vertical side surface of the mounting groove.

[0010] Further optimization involves providing a support rib with elastic deformation capability on the first bonding surface. When the grid cover is snapped onto the housing panel, the support rib abuts against the horizontal bottom surface of the mounting groove, and the support rib is hollowed out.

[0011] Further optimization involves providing a positioning protrusion on the horizontal bottom surface of the mounting groove, which extends into the groove to create a radial limit between the grid cover and the housing panel.

[0012] Further optimization involves providing a thickened protrusion on the inner wall of the outward-facing side of the groove, with the buckle protrusion located on the top surface of the thickened protrusion.

[0013] Preferably, the edge of the grid cover extends into a mounting ear, the mounting ear is provided with a screw post, the housing panel is provided with a positioning hole for the mounting ear to pass through, the housing panel is provided with a connecting hole, and the screw post and the connecting hole are fixedly connected by a screw connector, so that the grid cover is fixedly connected to the housing panel.

[0014] The technical advantages of this utility model are as follows: The grille cover has a buckle protrusion, the top of which is bent to one side to form a bent portion. The housing panel has corresponding mounting holes. After the buckle protrusion is inserted into the mounting hole and rotated, the bent portion is misaligned with the mounting hole and buckles onto the housing panel, thus achieving the installation of the grille cover and the housing panel. The structure is simple and the operation is convenient. The edge of the grille cover has a groove structure, and the housing panel has corresponding positioning protrusions. The positioning protrusions are located within the groove to form a radial limit, effectively preventing abnormal noise caused by the relative radial offset between the grille cover and the housing panel. The edge surface of the grille cover has supporting ribs with a hollow design, allowing the supporting ribs to rest between the grille cover and the passenger elevator panel, providing elastic buffering and preventing abnormal noise between the grille cover and the housing panel.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0025] This utility model includes a housing panel 1 and a grille cover 2. The housing panel 1 has an air outlet 11, which is a circular hole. The grille cover 2 is installed inside the air outlet 11, so the edge of the grille cover 2 is also circular, allowing the grille cover 2 to rotate along the air outlet 11. At least two snap-fit ​​protrusions 21 are evenly distributed around the edge of the grille cover 2. The snap-fit ​​protrusions 21 are axially oriented towards the inside of the air outlet 11. The bottom end of the snap-fit ​​protrusions 21 is connected to the grille cover 2 or is integrated with the grille cover 2. The top end of the snap-fit ​​protrusions 21 is bent and extended to one side to form a bent portion 211. In this embodiment, the snap-fit ​​protrusions 21 are thin plate structures, and the bent portion 211 rotates towards the grille cover 2. The bend and extend to one side to form a hook-like structure. A gap 22 is formed between the bottom surface of the bend 211 and the grille cover 2. The edge of the air outlet 11 has mounting holes 12 that correspond one-to-one with the buckle protrusions 21. Each buckle protrusion 21 is inserted into the corresponding mounting hole 12 and rotates in the bending direction. The bend 211 of each buckle protrusion 21 rotates to the edge surface of the air outlet 11 on the side of the mounting hole 12, so that the edge surface of the air outlet 11 at that point is located in the gap 22. The bottom of the bend 211 abuts against the edge surface of the air outlet 11. That is, the bend 211 and the mounting hole 12 are misaligned and snapped together, thereby realizing the snap-fit ​​connection of the grille cover 2 to the housing panel 1.

[0026] After the edge of the air outlet 11 is bent twice, an L-shaped mounting groove 13 is formed in the longitudinal section, namely a stepped mounting groove 13. The mounting groove 13 includes a horizontal bottom surface 131 and a vertical side surface 132. The mounting holes 12 are located on the horizontal bottom surface 131. Multiple mounting holes 12 are evenly distributed circumferentially along the horizontal bottom surface 131. When the grille cover 2 is snapped onto the housing panel 1, the edge of the grille cover 2 is embedded in the mounting groove 13. That is, the surface of the entire edge of the grille cover 2 is flush with the top of the vertical side surface 132, which is both aesthetically pleasing and serves to accommodate and support the grille.

[0027] Furthermore, the mounting hole 12 is inclined on one side of the bending part 211 in the direction of movement to form an inclined surface 121. The outer end of the inclined surface 121 is higher than the inner end, so that when the bending part 211 rotates, the bottom surface of the bending part 211 can move along the inclined surface 121. That is, the inclined surface 121 guides the bending part 211. If there is no inclined surface 121, the side wall of the mounting hole 12 is a vertical surface and is at a right angle to the surface of the housing panel 1. When the housing panel 1 has a mounting hole 12, burrs are easily generated on the edge of the mounting hole 12, which makes it easy for the bending part 211 to get stuck when it is inserted and rotated. The inclined surface 121 can avoid this situation, making it smoother when the buckle protrusion 21 is inserted into the mounting hole 12 and rotates.

[0028] Furthermore, the bottom surface of the bent portion 211 is inclined to form a guide surface 212. The distance between the guide surface 212 and the grid cover 2, that is, the gap 22 between the two, gradually increases along the bending direction of the bent portion 211, so that the bottom surface of the bent portion 211 also serves as the guide surface 212, which facilitates the rotational installation of the bent portion 211. The included angle between the guide surface 212 and the grid cover 2 is α, where α ≥ 5°.

[0029] Furthermore, the housing panel 1 is a sheet metal part, that is, a thin metal plate with uniform thickness, usually a galvanized plate with a wall thickness of 0.6 to 0.8 mm. The thickness of the housing panel 1 is T. The distance between the root of the guide surface 212 and the grid cover 2 is S, where S≤T+0.3 mm. The included angle α between the guide surface 212 and the grid cover 2 is used to ensure a tight fit between the buckle protrusion 21 and the housing panel 1.

[0030] Furthermore, the edge of the grille cover 2 is provided with circumferentially extending grooves 23. The grooves 23 form annular shapes along the edge of the grille cover 2. When the grille cover 2 is snapped onto the housing panel 1, the groove opening 231 faces the horizontal bottom surface 131 of the mounting groove 13. The two horizontal top surfaces where the groove opening 231 is located serve as mating surfaces 1 232, which are close to or attached to the horizontal bottom surface 131 of the mounting groove 13. The outer wall of the outer side of the groove 23 serves as mating surface 233, which is close to or attached to the vertical side surface 132 of the mounting groove 13, so that the grille cover 2 can be stably embedded in the housing panel 1.

[0031] Furthermore, the mating surface 232 is provided with a support rib 234 that has elastic deformation capability. The support rib 234 has a certain length and extends in an arc shape along the mating surface 232, that is, along the edge of the grid cover 2. The support rib 234 is integrally set with the mating surface 232. The support rib 234 is convex in shape, and its top surface is horizontal. When the grid cover 2 is snapped to the housing panel 1, the top surface of the support rib 234 abuts against the horizontal bottom surface 131 of the mounting groove 13. The support rib 234 plays an elastic buffering role, avoiding hard collision between the grid cover 2 and the housing panel 1, thereby avoiding abnormal noise caused by the collision. The support rib 234 is hollowed out, that is, it has holes, which is conducive to the deformation of the support rib 234.

[0032] Furthermore, the horizontal bottom surface 131 of the mounting groove 13 is provided with a positioning protrusion 133. The positioning protrusion 133 is formed by stamping the horizontal bottom surface 131, that is, the positioning protrusion 133 is formed by protruding and deforming from the horizontal bottom surface 131. The positioning protrusion 133 can be spherical or cylindrical. The top of the positioning protrusion 133 extends into the groove 23 so that a radial limit is formed between the grid cover 2 and the housing panel 1, which plays a certain stabilizing role for the grid cover 2 and can effectively avoid abnormal noise caused by the axial deviation of the grid cover 2's own central axis.

[0033] Furthermore, the inner wall of the outward-facing side of the groove 23 is provided with a thickened protrusion 235, and the snap-fit ​​protrusion 21 is provided on the top surface of the thickened protrusion 235, which enhances the strength of the snap-fit ​​protrusion 21 and makes the snap-fit ​​protrusion 21 less prone to deformation during assembly.

[0034] Furthermore, the edge of the grid cover 2 extends into a mounting ear 24. The housing panel 1 has a positioning hole 14 for the mounting ear 24 to pass through. The mounting ear 24 has a screw post 241. The housing panel 1 has a connecting hole 15. A screw connector is installed in the screw post 241. The screw connector passes through the connecting hole 15 to form a connection, further fixing the grid cover 2. The screw post 241 is set on the grid cover 2, which can avoid the risk of the screw connector slipping due to multiple installations and removals of the grid cover 2, thus increasing the number of times the grid cover 2 can be installed and removed.

[0035] In this embodiment, the number of buckle protrusions 21 is usually set to eight, and the number of mounting holes 12 is also eight, which correspond one-to-one to facilitate the assembly operation between the grid cover 2 and the housing panel 1, and has good stability, while also reducing abnormal noise caused by vibration between the two.

[0036] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
