Description

Technical Field

[0002] At present, in order to prevent dust, floccules and other pollutants from entering the casing of the cabinet or column indoor unit of the vertical air conditioner, a filter 1' is generally installed on the air inlet grille of the indoor unit to filter the incoming air. In order to facilitate the replacement and maintenance of the filter 1', the filter 1' is connected to the air inlet grille via a track-type pull-out structure. Figure 1 and Figure 2 As shown, the grille body of the air inlet grille forms a U-shaped guide groove on the upper and lower sides of each air inlet window, the outer groove wall of the guide groove forms an outer guide rib 2' flush with the rib 4', and the inner groove wall forms an inner guide rib 3' aligned with the outer guide rib 2' front and back, so as to cause the filter 1' to be confined between the inner guide rib 3' and the outer guide rib 2'.

[0003] In the existing air inlet grille manufacturing process, due to the U-shaped groove structure of the guide rail groove, it is necessary to use a mold 5' with a sloping roof structure during the injection molding process to facilitate demoulding; at the same time, due to the larger area of ​​the air inlet grille, the guide rail groove is also larger, resulting in the mold 5' and the sloping roof thereon being larger and more complex, which in turn causes the air inlet grille that relies on the mold 5' for manufacturing to have a higher manufacturing cost, which is not conducive to the promotion and sales of air conditioners using the air inlet grille.

[0046] Figure 3 : is a schematic structural diagram of an air inlet grille according to an embodiment of the utility model, such as Figure 3 As shown, and refer to Figures 4 to 5 The embodiment of the utility model provides an air inlet grille of an air conditioner, comprising a main frame 100 and a transversely extending guide rib 130. The main frame 100 comprises at least two transversely extending transverse frames 110, each of which is longitudinally spaced apart so that an air inlet window 700 is defined between two adjacent transverse frames 110. The air inlet window 700 is configured to allow air to enter from a first side to a second side. An L-shaped filter track 300 is formed on one side of the transverse frame 110 that is connected to the air inlet window 700, and a first track wall 310 is formed on one side of the filter track 300, which is spaced between the transverse frame 110 and the air inlet window 700, and a second track wall 320 is formed on the other side that extends from the second side of the transverse frame 110 into the air inlet window 700. The guide rib 130 is integrally formed in the air inlet window 700. The guide ribs 130 and the second track walls 320 are staggered and arranged in a one-to-one correspondence in the longitudinal direction, and the second side surface of the guide ribs 130 and the first side surface of the second track wall 320 are separated in the depth direction of the air inlet window 700 .

[0047] In the present embodiment, the air inlet grille is located on the rear housing 210 of the air conditioner, and the filter is installed at the air inlet grille to filter the wind that needs to pass through the air inlet window 700. The first side and the second side are arranged relatively to each other, that is, the first side may be a side relatively far away from the air conditioner, and the second side may be a side relatively close to the air conditioner. When the air inlet window 700 is a planar structure, the first side may be the rear side, and the second side may be the front side. When the air inlet window 700 is a curved structure with the opening facing forward, the first side may be the outer side, and the second side may be the inner side. For a vertical air conditioner, the transverse direction is the horizontal direction, and the longitudinal direction is the vertical direction.

[0048] The horizontal frame 110 is used to define the air inlet window 700 in the longitudinal direction. A filter can be installed corresponding to each air inlet window 700. One or both ends of the filter are located between the filter track 300 and the guide rib 130 in the longitudinal direction, and the second track wall 320 and the guide rib 130 limit the filter in the depth direction along the air inlet window 700, and the first track wall 310 limits the filter in the longitudinal direction to fix the filter. The filter can also be inserted or pulled out from between the filter track 300 and the guide rib 130 in the transverse direction, thereby realizing the installation and removal of the filter.

[0049] Furthermore, the guide rib 130 and the second track wall 320 are separated in the depth direction of the air inlet window 700, and the guide rib 130 is spaced apart from the first track wall 310 in the vertical direction. During the injection molding process, the filter track 300 of the air inlet grille is easy to mold, and does not require the use of a mold with a sloping roof structure, and is easy to demould. This reduces the manufacturing cost of the air inlet grille, which is conducive to the promotion and sales of air conditioners using the air inlet grille.

[0050] In some embodiments of the present invention, Figure 4 As shown, the adjacent edges of the second side surface of the guide rib 130 and the first side surface of the second track wall 320 are spaced apart in the longitudinal direction to define a parting line between the adjacent edges of the two.

[0051] In this embodiment, the air inlet grille may be integrally injection molded. Specifically, during processing, an upper mold is disposed on one side of the air inlet window 700 in the depth direction, and a lower mold is disposed on the other side of the air inlet window 700 in the depth direction.

[0052] For example, when the air inlet window 700 is an arc-shaped structure with the opening facing forward, a lower mold can be arranged on the inner side and an upper mold can be arranged on the outer side. At this time, the guide rib 130 and the second track wall 320 are arranged at intervals in the vertical direction, and when projected along the depth direction of the air inlet window 700, there is no interference between the guide rib 130 and the second track wall 320. In this way, a parting line can be arranged at the adjacent edges of the second side surface of the guide rib 130 and the first side surface of the second track wall 320 at the longitudinal interval, so that the air inlet grille does not have a sloping roof structure during the injection molding process, which is convenient for molding and demoulding.

[0053] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the air inlet grille further includes a transverse rib 140 extending transversely. The transverse rib 140 is integrally formed in the air inlet window 700, and the transverse rib 140 is located on a side of the guide rib 130 away from the transverse frame 110. And the second side surface of the transverse rib 140 is located on the first side of the second side surface of the guide rib 130.

[0054] In this embodiment, the transverse rib 140 further limits the filter to prevent the filter from falling off. The second side surface of the transverse rib 140 is farther from the filter than the second side surface of the guide rib 130, which has less interference with the filter when installing or removing the filter, making it easier to install and remove the filter, thereby improving the user experience.

[0055] Of course, in other embodiments of the present invention, the second side surface of the transverse rib 140 and the second side surface of the guide rib 130 may also be located on the same plane.

[0056] In this embodiment, the second side surface of the transverse rib 140 and the second side surface of the guide rib 130 are at the same distance from the filter screen, thereby further limiting the position of the filter screen, making the installation of the filter screen more secure.

[0057] In some embodiments of the present invention, Figure 3 and Figure 4As shown, in each air inlet window 700 , there are at least two transverse ribs 140 , and the transverse ribs 140 are spaced apart in the longitudinal direction.

[0058] In this embodiment, at least two transverse ribs 140 are used to limit the position of the filter. The provision of multiple transverse ribs 140 allows the filter installed at the air inlet grille to be fixed more stably and more effectively prevents the filter from falling off.

[0059] In some embodiments of the present invention, Figure 4 As shown, the distance h1 between the transverse rib 140 and the guide rib 130 is smaller than the distance h2 between two adjacent transverse ribs 140 .

[0060] In this embodiment, when the filter is installed at the air inlet grille, the two ends of the filter are respectively fixed in two spaced filter tracks 300. The transverse ribs 140 are closer to the guide ribs 130 to further limit the positions of the two ends of the filter close to the filter track 300, preventing the filter from detaching from the filter track 300, thereby making the filter more firmly fixed at the air inlet grille.

[0061] In some embodiments of the present invention, the transverse ribs 140 may be guide ribs 130 .

[0062] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the air inlet grille also includes a first longitudinal rib 400 extending longitudinally, the first longitudinal rib 400 is integrally formed in the air inlet window 700, and the first longitudinal rib 400 bridges between the guide rib 130 and the transverse rib 140 and / or between two adjacent transverse ribs 140.

[0063] In this embodiment, a grid is formed between the guide ribs 130, the transverse ribs 140 and the first longitudinal ribs 400, so that the structure of the air inlet grille is more stable, the risk of deformation of the air inlet grille is reduced, and the service life of the air inlet grille is extended. In addition, the one-piece structure can further improve the structural strength of the air inlet grille, and the one-piece structure is easy to manufacture, thereby reducing the manufacturing cost.

[0064] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the first longitudinal rib 400 is located on the second side surface of the guide rib 130 or the first side of the second side surface of the transverse rib 140 .

[0065] In this embodiment, when the filter is installed on the air inlet grille, the filter is located between the second guide rail wall and the guide rib 130 in the horizontal direction, and the first longitudinal rib 400 is located at a position far from the filter. When installing or removing the filter, the first longitudinal rib 400 will not interfere with the filter, so that the filter can be installed or removed smoothly, avoiding the filter from getting stuck during the installation and removal process, and improving the installation and removal efficiency of the filter.

[0066] In some embodiments of the present invention, Figure 3 As shown, the air inlet grille further includes a second longitudinal rib 500 extending longitudinally, and the second longitudinal rib 500 is integrally formed in the air inlet window 700. The main frame 100 further includes two longitudinal frames 120 extending longitudinally, the two longitudinal frames 120 are spaced apart in the transverse direction, and the two longitudinal frames 120 are integrally formed at both ends of each transverse frame 110, so that the two longitudinal frames 120 surround the transverse sides of the air inlet window 700. One end of the transverse rib 140 is connected to the second longitudinal rib 500, and the other end is directly or indirectly connected to one longitudinal frame 120. In addition, the other longitudinal frame 120 is spaced apart from the second longitudinal rib 500 in the transverse direction.

[0067] In this embodiment, the two longitudinal frames 120 and the transverse frames 110 at both ends define the air inlet window 700. The second longitudinal ribs 500 are arranged at intervals on one side of one longitudinal frame 120, so that one transverse end of the filter can pass between the second longitudinal ribs 500 and the longitudinal frame 120, thereby allowing the filter to be inserted into the filter track 300 in the transverse direction.

[0068] In some embodiments of the present invention, Figure 3 As shown, the air inlet grille further includes a third longitudinal rib 600 extending longitudinally, and the third longitudinal rib 600 is integrally formed in the air inlet window 700, so that the air inlet window 700 is laterally spaced apart by the third longitudinal rib 600. At least one end of the third longitudinal rib 600 is located between the guide rib 130 and the transverse frame 110.

[0069] In this embodiment, the third longitudinal rib 600 has the function of supporting and strengthening the structure of the air inlet grille. The guide rib 130, the transverse rib 140, etc. can be fixedly connected to the transverse frame 110 or the filter track 300 through the third longitudinal rib 600. The width of the third longitudinal rib 600 is set wider than the second longitudinal rib 500, and is symmetrically arranged at the air inlet window 700 to improve the strength of the air inlet grille. In addition, the one-piece molding structure can further improve the structural strength of the air inlet grille, reduce the risk of deformation of the air inlet grille, and thus extend the service life of the air inlet grille.

[0070] In some embodiments of the present invention, the second side surface of the end of the third longitudinal rib 600 between the guide rib 130 and the transverse frame 110 is flush with the second side surface of the guide rib 130 .

[0071] In this embodiment, the second side surface of the third longitudinal rib 600 limits the filter at the first side to prevent the filter from detaching, so that the filter is fixed more firmly at the air inlet grille.

[0072] Alternatively, in some other embodiments of the present invention, the second side surface of the end of the third longitudinal rib 600 between the guide rib 130 and the transverse frame 110 is located on the first side of the second side surface of the guide rib 130 .

[0073] In this embodiment, the second side surface of the end of the third longitudinal rib 600 is located on one side of the second side surface of the guide rib 130, so that the third longitudinal rib 600 is away from the installation position of the filter, avoiding interference with the filter, facilitating the installation or disassembly of the filter, and preventing the filter from getting stuck during the disassembly process, thereby improving the installation and disassembly efficiency of the filter.

[0074] In some embodiments of the present invention, Figure 3 As shown, the first side surface of the end of the third longitudinal rib 600 between the guide rib 130 and the transverse frame 110 forms a cavity recessed toward the second side.

[0075] In this embodiment, the cavity recessed toward the second side or the cavity recessed toward the first side is a square groove, which can reduce material costs. The structure of the groove can also increase the strength of the third longitudinal rib 600, making the structure of the air inlet grille more stable and less prone to deformation, thereby extending the service life of the air inlet grille.

[0076] In some embodiments of the present invention, the second side surface of the end of the third longitudinal rib 600 between the guide rib 130 and the transverse frame 110 forms a cavity that is recessed toward the first side.

[0077] In some embodiments of the present invention, Figure 3 As shown, there are at least three transverse frames 110, wherein two on both sides of the longitudinal direction of each transverse frame 110 are first transverse frames 111, and at least one between the two first transverse frames 111 is a second transverse frame 112. The first transverse frame 111 forms a filter track 300 on one side close to the second transverse frame 112, and the second transverse frame 112 forms a filter track 300 on both sides of the longitudinal direction.

[0078] When the vertical air conditioner is high, in order to ensure the structural strength, multiple air inlet windows 700 and multiple filters need to be provided. In this embodiment, there are at least three horizontal frames 110, so that at least two filters can be installed at the air inlet grille, thereby reducing the size of the filter. Smaller filters are easy to manufacture and reduce the production cost of the filters. In addition, smaller filters are easy for users to disassemble and are also easy for later maintenance, thereby improving the user experience.

[0079] The utility model also provides an air conditioner, such as Figure 5 As shown, it includes a housing 200, a heat exchange component 800 and a fan component. The housing 200 includes a rear housing 210 and an air inlet grille in any of the above embodiments, the rear housing 210 opens forward, and the air inlet grille is connected to the forward opening of the rear housing 210. The heat exchange component 800 is arranged in the housing 200. The fan component is arranged in the housing 200.

[0080] In this embodiment, the air conditioner introduces the normal temperature airflow into the casing 200 through the opening on the rear casing 210. When passing through the opening, the airflow is filtered by the filter at the air inlet grille and then enters the casing. After the airflow passes through the heat exchange component 800 in the casing to become the heat exchange airflow, the fan blows the heat exchange airflow into the room through the air outlet of the air conditioner to heat the indoor air. The air inlet grille is installed on the rear casing 210, and the filter is installed at the air inlet grille to filter the wind that needs to pass through the air inlet window 700. At least one end of the filter is located between the filter track 300 and the guide rib 130, and the second track wall 320 and the guide rib 130 limit the front and rear directions of the filter to fix the filter.

[0081] When the user needs to clean or replace the filter, the filter can also be pulled out from between the filter track 300 and the guide rib 130 to achieve installation and removal of the filter. Moreover, the guide rib 130 and the second track wall 320 are separated in the depth direction of the air inlet window 700, and the guide rib 130 is spaced apart from the first track wall 310 in the vertical direction. During the injection molding process, the filter track 300 of the air inlet grille is easy to mold and demold, and there is no need to use a mold with a sloping roof structure. This reduces the manufacturing cost of the air inlet grille, which is conducive to the promotion and sales of air conditioners using the air inlet grille.

[0082] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
