Description

Technical Field

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

[0002] Air conditioner indoor units typically have an air inlet grille, which forms an air intake. When the air conditioner is working, outside air enters through the air inlet, passes through the heat exchanger, and then flows out through the air outlet, thus regulating the indoor temperature. After prolonged use, dust, hair, and other debris will accumulate on the surface of the air inlet grille or on the inner wall of the air inlet. If not cleaned in time, this will affect the air intake efficiency.

[0003] To facilitate cleaning dust and other debris from the air intake grille, the existing grille is movably mounted on the panel. Cleaning is simple; just rotate the grille to open it. However, the existing grille is prone to interference with the panel during rotation, causing uneven rotation. Over time, this can lead to wear and deformation of components, and also affects operational efficiency. Utility Model Content

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0037] like Figures 1 to 9 As shown, this utility model provides an air inlet housing assembly.

[0038] An air conditioner includes an indoor unit and an outdoor unit. The indoor unit includes an air inlet housing assembly, an indoor heat exchanger, and a fan. The air inlet housing assembly is provided with an air inlet 126 and an air outlet. Under the action of the fan, outside air enters the air duct through the air inlet 126, passes through the indoor heat exchanger, and then flows out from the air outlet.

[0039] The air inlet housing assembly includes a panel 10, which has a horizontally extending mounting surface 101 and a mating surface 102 connected to the mounting surface 101. The mating surface 102 is located outside the mounting surface 101 and forms an angle between the mating surface 102 and the mounting surface 101. The mounting surface 101 has a clearance hole 103.

[0040] Mounting component 11 is disposed on mounting surface 101, and mounting component 11 is provided with mounting shaft 111;

[0041] The air inlet grille 12 is provided with a transition part 13 and a limiting insertion part 14. The mounting shaft 111 is located in the transition part 13. The transition part 13 can rotate around the mounting shaft 111. The limiting insertion part 14 is correspondingly provided with the clearance hole 103. When the air inlet grille 12 rotates relative to the panel 10, a clearance gap is formed between the outer wall surface of the air inlet grille 12 and the mating surface 102.

[0042] like Figure 1 As shown, the panel 10 has a mounting area 104 for mounting the air inlet grille 12. The mounting area 104 is adapted to the shape of the air inlet grille 12. For example, the mounting area 104 defines a rectangular area. When the air inlet grille 12 is closed, it covers the mounting area 104; when the air inlet grille 12 is open, it exposes the mounting area 104. Figure 4As shown, a mounting surface 101 is provided on one long side of the mounting area 104 to provide a mounting position for the air intake grille 12. A mating surface 102 is also provided on one side of the mounting surface 101. When the air intake grille 12 rotates, the outer wall surface of the air intake grille 12 may interfere with the mating surface 102. By ensuring that the outer wall surface of the air intake grille 12 always forms a clearance with the mating surface 102 when the air intake grille 12 rotates, interference can be prevented and the air intake grille 12 can be ensured to rotate smoothly.

[0043] To reduce the probability of interference between the air inlet grille 12 and the mating surface 102, in some embodiments, the mounting surface 101 is inclined downwards in a direction away from the mating surface 102. This increases the gap between the air inlet grille 12 and the mating surface 102 when the air inlet grille 12 rotates, preventing the air inlet grille 12 from getting stuck during rotation. In other embodiments, the mounting surface 101 extends horizontally. Furthermore, the mating surface 102 can extend vertically or extend outwards in a direction away from the mounting surface 101.

[0044] The aforementioned panel 10 having a horizontally extending mounting surface 101 means that the mounting surface 101 extends horizontally or approximately horizontally, as described in the above embodiments. The included angle formed between the mounting surface 101 and the mating surface 102 is preferably 90 degrees or greater, in order to ensure the size of the clearance and avoid interference between the air inlet grille 12 and the mating surface 102.

[0045] Furthermore, the adapter 13 defines a space for the mounting shaft 111 to be inserted. The cross-sectional area of ​​this space is larger than the cross-sectional area of ​​the mounting shaft 111 (e.g., the cross-section of the mounting shaft 111 is circular). When the air inlet grille 12 rotates, by moving the air inlet grille 12 away from the mating surface 102, the clearance can be increased and the anti-interference performance can be improved.

[0046] When the air inlet grille 12 is closed, it horizontally covers the installation area 104. To reduce interference, such as Figure 6 As shown, one side of the clearance hole 103 extends onto the transition surface 105 inside the mounting surface 101; to reduce interference during the rotation of the air inlet grille 12, the other side of the clearance hole 103 extends onto the mating surface 102. Preferably, as shown... Figure 3 As shown, a gap is formed between the limiting insertion part 14 and the surrounding area of ​​the clearance hole 103, which can further reduce interference.

[0047] When the air intake grille 12 needs to be cleaned, rotate the air intake grille 12 to the open position. After cleaning, rotate the air intake grille 12 back to the closed position. The operation is simple and convenient.

[0048] In a preferred embodiment of this utility model, the air inlet grille 12 includes a grille body 121 and a surrounding edge 122 extending from one edge of the grille body 121 away from the grille body 121. The transition portion 13 and the limiting insertion portion 14 are both disposed on the surrounding edge 122. Figure 1 and Figure 7 As shown, the main body 121 of the grille has a connecting end and a free end. The connecting end is used for rotatable mounting on the panel 10, and the free end can be separated from the panel 10 to allow the air inlet grille 12 to rotate and open. A surrounding edge 122 is provided at the end of the connecting end to provide a mounting structure for the installation and rotation of the air inlet grille 12.

[0049] The adapter 13 is provided with at least two, for example, such as Figure 7 As shown, there are two transition parts 13, with the middle position of the perimeter 122 serving as the dividing line. The two transition parts 13 are respectively located on both sides, for example, near the two ends of the perimeter 122 along its length. Multiple limiting insertion parts 14 are provided, such as... Figure 7 An example is shown where five limiting connectors 14 are provided, spaced apart along the length of the perimeter 122.

[0050] To facilitate the installation of the air intake grille 12, the surrounding edge 122 is a discontinuous structure, such as... Figure 7 As shown, one side of the transition part 13 is connected to the perimeter 122, and the other side is open, providing conditions for avoiding the mounting member 11. The perimeter 122 includes, for example, three spaced sub-perimeters 1221. Each of the two sub-perimeters 1221 at both ends is provided with a transition part 13, and the transition part 13 is located at one end of the sub-perimeter 1221, forming a avoidance area for the mounting member 11 between the transition part 13 and the sub-perimeter 1221 in the middle position.

[0051] In some embodiments, the transition portion 13 extends in an arc shape from the perimeter 122 toward the main body 121 of the gate plate.

[0052] like Figure 8 As shown, the adapter 13 forms a shaft hole for the mounting shaft 111 to be inserted, and the arc-shaped extension helps to form a smooth and rounded surrounding space, reducing wear between it and the mounting shaft 111.

[0053] Furthermore, the end of the transition section 13 away from the edge 122 is provided with a straight-extending flange 131. By providing the flange 131, it is beneficial to increase the internal space of the transition section 13, provide greater freedom for the rotation of the air intake grille 12, and reduce the probability of interference between the air intake grille 12 and the panel 10.

[0054] The outer end of the flange 131 can extend to the inner wall surface of the grille body 121, or the outer end of the flange 131 can form a first gap with the inner wall surface of the grille body 121, depending on actual needs. That is, the transition part 13 can be set as a closed structure or a non-closed structure in the circumferential direction, as long as it meets the installation requirements of the air inlet grille 12 and achieves the required rotation effect.

[0055] Based on the arc-shaped extension of the transition portion 13, in some embodiments, a reinforcing plate 123 is provided on the inner side of the perimeter 122, which is parallel to the perimeter 122, and one end of the reinforcing plate 123 is connected to the top of the transition portion 13.

[0056] like Figure 8 As shown, the transition portion 13 is disposed between the perimeter 122 and the reinforcing plate 123, which can improve the overall structural strength of the transition portion 13, prevent deformation or breakage of the transition portion 13, and ensure the service life of the structure. A cavity is formed between the perimeter 122 and the reinforcing plate 123 to provide clearance and prevent interference with other structures on the panel 10. Preferably, reinforcing ribs can be provided between the perimeter 122 and the reinforcing plate 123 to further enhance the structural strength.

[0057] Furthermore, the inner side of the reinforcing plate 123 is provided with a grid 124, and a reinforcing rib 125 is provided between the grid 124 and the transition part 13.

[0058] like Figure 7 and Figure 8 As shown, the main body 121 of the grille has multiple grille bars 124 extending along its length, and air inlets 126 are formed between adjacent grille bars 124. The main body 121 of the grille also has connecting ribs connecting the multiple grille bars 124, dividing the air inlets 126 into multiple small-sized elongated air inlets 126. A reinforcing rib 125 is provided between the grille bar 124 closest to the reinforcing plate 123 and the top of the transition part 13, which can further improve the structural strength of the transition part 13, reduce structural deformation and damage rate, and extend the structural life.

[0059] In some embodiments, the limiting insertion portion 14 is, for example, a plug-in piece, which extends downward from the end of the perimeter 122. Correspondingly, the clearance hole 103 adopts a square structure. To improve the structural strength of the location of the limiting insertion portion 14, a reinforcing plate 123 is provided on the inner side of the perimeter 122, and a reinforcing portion 127 corresponding to the limiting insertion portion 14 is provided between the perimeter 122 and the reinforcing plate 123, which can improve the structural strength of the connection end of the air inlet grille 12.

[0060] Based on the above embodiments, as a preferred embodiment of the present invention, one of the mounting surface 101 and the mounting component 11 is provided with a slide rail 15, and the other is provided with a slide groove 16 that cooperates with the slide rail 15, and the mounting component 11 is slidably mounted on the mounting surface 101.

[0061] The mounting component 11 of this invention is slidably mounted on the mounting surface 101, providing favorable conditions for the installation of the air inlet grille 12. In some embodiments, such as Figure 2 or Figure 5 As shown, the mounting surface 101 is provided with a slide rail 15, and the bottom of the mounting component 11 is provided with a slide groove 16 that mates with the slide rail 15. The mounting component 11 can move along the slide rail 15 through the slide groove 16.

[0062] To prevent interference between the adapter 13 and the mounting shaft 111 during the installation of the air intake grille 12, this utility model provides a reliable installation method for the air intake grille 12. When the air intake grille 12 is not installed, the mounting member 11 has a first position on the mounting surface 101. This first position allows the mounting shaft 111 to be located outside the adapter 13 when the air intake grille 12 is aligned with the mounting surface 101 (i.e., when the mounting shaft 111 is not inserted into the adapter 13). Then, the mounting member 11 can slide along the mounting surface 101 to insert the mounting shaft 111 into the adapter 13. Finally, the mounting member 11 slides into the second position.

[0063] In some embodiments, such as Figure 2 , Figure 5 and Figure 9 As shown, the mounting component 11 includes a base 112 and a horizontally extending mounting shaft 111 disposed on the base 112. The lower outer side wall of the base 112 is provided with an outwardly protruding limiting protrusion 113.

[0064] Mounting surface 101 has a limiting buckle 17 on the outside of mounting part 11. The limiting buckle 17 limits the seat 112 to the mounting surface 101. When mounting part 11 slides into place, the limiting protrusion 113 cooperates with the side stop of the limiting buckle 17.

[0065] like Figure 2 As shown, the mounting part 11 is in the first position, at which time the limiting protrusion 113 is located behind the limiting buckle 17. As the mounting part 11 slides forward, the air inlet grille 12 is installed by inserting the mounting shaft 111 and the adapter 13. Finally, the mounting part 11 slides to the second position, and the limiting protrusion 113 reaches the front of the limiting buckle 17 and the two stop and cooperate, which can simultaneously limit the mounting part 11 and ensure the cooperation effect between the mounting shaft 111 and the adapter 13.

[0066] For example, a limiting block 171 is provided on the front side of the limiting buckle 17. When the mounting part 11 slides to the second position, the limiting protrusion 113 and the limiting block 171 stop and cooperate.

[0067] The mounting component 11 has a certain degree of elasticity. By pressing the two limiting protrusions 113 on both sides, it can pass through the two limiting buckles 17 to reach the front side of the limiting buckles 17. Preferably, the two ends of the limiting protrusions 113 along the sliding direction are provided with inclined surfaces, which can play a role in avoiding obstacles and facilitate the deformation of the mounting component 11 by pressing.

[0068] Furthermore, such as Figure 2 As shown, a guide seat 18 is provided on the mounting surface 101. The guide seat 18 is provided with a through hole 181. The mounting shaft 111 can be inserted into the adapter 13 through the through hole 181, which can realize the movement guidance of the mounting shaft 111, increase the support for the mounting shaft 111, prevent the mounting shaft 111 from shifting and increasing the friction between the mounting shaft 111 and the adapter 13, thus affecting the installation reliability.

[0069] The air inlet housing assembly provided by this utility model cooperates with the mounting shaft 111 through the adapter 13. When the air inlet grille 12 rotates, the adapter 13 rotates around the mounting shaft 111 to ensure the rotation reliability of the air inlet grille 12. At the same time, when the air inlet grille 12 rotates, a clearance gap is formed between the outer wall surface of the air inlet grille 12 and the mating surface 102, which can ensure that the air inlet grille 12 will never touch the mating surface 102 during the rotation process, avoiding interference between the air inlet grille 12 and the panel 10, ensuring smooth rotation of the air inlet grille 12 and improving the rotation efficiency of the air inlet grille 12. Furthermore, by cooperating with the limiting plug 14 and the clearance hole 103, interference between the limiting plug 14 and the mounting surface 101 can be avoided. On the other hand, the limiting plug 14 and the clearance hole 103 form a limiting structure, which is beneficial to improve the installation efficiency of the air inlet grille 12 by aligning the two during installation. It can also limit the installation position of the air inlet grille 12 and improve the installation reliability of the air inlet grille 12 on the panel 10.

[0070] This utility model also provides an air conditioner, including the air inlet housing assembly described in the above embodiments and examples. The air conditioner has all the beneficial effects of the air inlet housing assembly described in the above embodiments and examples, which will not be repeated here.

[0071] The air conditioner provided by this utility model, through the cooperation of the adapter 13 and the mounting shaft 111, ensures the reliability of the rotation of the air inlet grille 12 when the air inlet grille 12 rotates, with the adapter 13 rotating around the mounting shaft 111. Simultaneously, when the air inlet grille 12 rotates, a clearance gap is formed between the outer wall surface of the air inlet grille 12 and the mating surface 102, ensuring that the air inlet grille 12 will never touch the mating surface 102 during rotation, thus avoiding interference between the air inlet grille 12 and the panel 10. This ensures smooth rotation of the air inlet grille 12 and improves its rotation efficiency. Furthermore, through the cooperation of the limiting insertion part 14 and the clearance hole 103, interference between the limiting insertion part 14 and the mounting surface 101 is avoided. On the other hand, the limiting insertion part 14 and the clearance hole 103 form a limiting structure, which not only facilitates the alignment of the two during air inlet grille 12 installation, improving the installation efficiency of the air inlet grille 12, but also restricts the installation position of the air inlet grille 12, improving the installation reliability of the air inlet grille 12 on the panel 10.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to 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 of the embodiments of this utility model.
