Description

Technical Field

[0001] This application belongs to the field of air conditioning technology, and in particular relates to an air intake grille and an air conditioner. Background Technology

[0002] Air conditioners have air intake grilles at their inlets. Because of these grilles, airflow is obstructed as it enters the air conditioner, reducing the amount of air entering. Current technology often uses thinner grille bars to ensure sufficient airflow, but this reduces the grille's structural strength, making it prone to breakage during transport and installation. Utility Model Content

[0003] This application provides an air intake grille and an air conditioner to solve the problem that existing air intake grilles are easily broken during transportation and installation.

[0004] In a first aspect, embodiments of this application provide an air inlet grille, the air inlet grille including a frame, grille bars and reinforcing ribs, a plurality of grille bars being spaced apart in the frame along a first direction, an air inlet hole being formed between two adjacent grille bars, the air inlet hole being an arc-shaped structure arranged arc-shaped along the first direction; the reinforcing ribs are located on the leeward side of the grille bars and extend along the first direction, and the plurality of grille bars are all connected to the reinforcing ribs.

[0005] Optionally, the reinforcing rib includes a first reinforcing rib, an intermediate reinforcing rib, and a second reinforcing rib. The first reinforcing rib, the intermediate reinforcing rib, and the second reinforcing rib are arranged at intervals along a second direction, which is perpendicular to the first direction. The middle portion of each of the plurality of grid strips is connected to the intermediate reinforcing rib, and both ends of each grid strip are connected to the first reinforcing rib and the second reinforcing rib, respectively.

[0006] Optionally, both the first reinforcing rib and the second reinforcing rib have a reinforcing portion at the part facing the air inlet, and the reinforcing portion is disposed on at least one side surface of the first reinforcing rib and the second reinforcing rib along the first direction.

[0007] Optionally, the thickness of the intermediate reinforcing rib is less than the thickness of the first reinforcing rib, and the thickness of the intermediate reinforcing rib is less than the thickness of the second reinforcing rib.

[0008] Optionally, the leeward side of the grille bar is provided with a limiting rib, the limiting rib having a limiting groove, and the reinforcing rib is inserted into the limiting groove to limit the position in the second direction.

[0009] Optionally, in the arc direction of the air inlet, the ventilation area of ​​the air inlet gradually increases from both ends of the air inlet towards the middle.

[0010] Optionally, the air inlets are symmetrically distributed with respect to the centerline of the frame.

[0011] Optionally, the frame includes a first side, a second side, a third side, and a fourth side connected end to end, with the first side and the third side being opposite to each other, the second side and the fourth side being opposite to each other, and the two ends of the grid strip being connected to the first side and the third side, respectively.

[0012] Optionally, the frame and the plurality of the grid strips are integrally formed.

[0013] Secondly, this application embodiment also provides an air conditioner, the air conditioner including a housing and the above-mentioned air inlet grille, the housing having an air inlet, and the air inlet grille being disposed at the air inlet.

[0014] The air intake grille and air conditioner provided in this application embodiment increase the structural strength of the air intake grille by setting reinforcing ribs extending along a first direction on the leeward side of the grille strips, and by connecting multiple grille strips to the reinforcing ribs. By designing the air intake hole as an arc-shaped structure arranged along the first direction, the inner wall surface of the air intake hole is an arc-shaped surface. The arc-shaped surface can reduce the flow resistance of the incoming airflow, thereby increasing the air intake volume. Thus, while ensuring that the air intake volume is not affected, the structure of the air intake grille is more reliable and stable, and it is not easy to break during transportation and installation.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0024] This application provides an air intake grille, such as Figures 1-3 As shown, the air inlet grille includes a frame 110, grille bars 120, and reinforcing ribs 130. Multiple grille bars 120 are spaced apart within the frame 110 along the first direction Y. An air inlet hole 101 is formed between two adjacent grille bars 120. The air inlet hole 101 is an arc-shaped structure arranged in an arc along the first direction Y. The grille bars 120 have an air inlet side and a leeward side arranged opposite to each other. The reinforcing ribs 130 are located on the leeward side of the grille bars 120 and extend along the first direction Y. Multiple grille bars 120 are connected to the reinforcing ribs 130.

[0025] The air intake grille provided in this embodiment increases structural strength by providing reinforcing ribs 130 on the leeward side of the grille bars 120, with multiple grille bars 120 connected to the reinforcing ribs 130. By designing the air intake hole 101 as an arc-shaped structure along the first direction Y, the inner wall surface of the air intake hole 101 becomes an arc-shaped surface. This arc-shaped surface reduces the flow resistance of the incoming airflow, thereby increasing the air intake volume. Thus, while ensuring the air intake volume remains unaffected, the structure of the air intake grille becomes more reliable and stable, making it less prone to breakage during transportation and installation. It is understood that during the airflow passing through the air intake hole 101, the airflow can transition along the arc-shaped surface of the air intake hole 101, thereby reducing air intake resistance.

[0026] Optionally, in the arc direction of the air inlet 101, the ventilation area of ​​the air inlet 101 gradually increases from both ends towards the middle. This arrangement ensures that, in the arc direction of the air inlet 101, the ventilation area in the middle of the air inlet 101 is larger than the ventilation area at both ends, thus reducing the resistance in the middle area of ​​the air inlet 101 during air intake and ensuring that the air intake volume meets the standard.

[0027] It is understandable that when the air conditioner drives the airflow through the air intake grille to enter the air conditioner, since the negative pressure zone of the centrifugal fan is in the center, the air intake volume in the middle area is greater than that in the air intake grille. Therefore, the ventilation area in the middle of the air intake hole 101 is preferably larger than the ventilation area at both ends to ensure that the air intake volume meets the standard.

[0028] Optionally, the air inlets 101 are symmetrically distributed with respect to the center line of the frame 110, so that the air intake volume on both sides of the air intake grille is the same, preventing the grille strips 120 from deforming due to excessive local air intake, and making the air intake grille more aesthetically pleasing.

[0029] In some embodiments of this application, the frame 110 includes a first side 111, a second side 112, a third side 123 and a fourth side 124 connected from end to end. The first side 111 and the third side 123 are arranged opposite to each other, the second side 112 and the fourth side 124 are arranged opposite to each other, and the two ends of the grid strip 120 are respectively connected to the first side 111 and the third side 123.

[0030] Optionally, the frame 110 and multiple grid strips 120 can be integrally molded, specifically through injection molding. This not only eliminates the need to assemble the frame 110 with the multiple grid strips 120, improving production efficiency, but also results in higher strength and mechanical stability.

[0031] Optional, such as Figure 1As shown, the reinforcing rib 130 includes a first reinforcing rib 131, a middle reinforcing rib 132, and a second reinforcing rib 133. The first reinforcing rib 131, the middle reinforcing rib 132, and the second reinforcing rib 133 are arranged alternately along a second direction X, which is perpendicular to the first direction Y. The middle portion of each of the plurality of grille strips 120 is connected to the middle reinforcing rib 132, and both ends of each grille strip 120 are connected to the first reinforcing rib 131 and the second reinforcing rib 133, respectively. By arranging the plurality of reinforcing ribs 130 alternately along the second direction X, the overall structural strength of the air intake grille can be further increased. The middle reinforcing rib 132 can also prevent the middle portion of each grille strip 120 from bending downwards due to its own weight because of its excessive length. For example, the first direction Y can be the vertical direction of the frame 110, and the second direction X can be the horizontal direction of the frame 110.

[0032] Optionally, the thickness of the intermediate reinforcing rib 132 is less than the thickness of the first reinforcing rib 131, and the thickness of the intermediate reinforcing rib 132 is less than the thickness of the second reinforcing rib 133. That is, the thickness of the reinforcing rib 130 in the middle of the air intake grille is less than the thickness of the reinforcing ribs 130 at both ends. Here, the thickness of each reinforcing rib 130 refers to the width of the reinforcing rib 130 along the second direction X.

[0033] It is understandable that when the air conditioner drives the airflow through the air inlet grille to enter the air conditioner, since the negative pressure zone of the centrifugal fan is in the center, the air intake volume in the middle area of ​​the air inlet grille is greater. That is, the middle area of ​​the air inlet grille is the main air intake area. Therefore, it is preferable to set the thickness of the middle reinforcing rib 132 to be less than the thickness of the first reinforcing rib 131 and the second reinforcing rib 133, so as to reduce the impact of the middle reinforcing rib 132 on the air intake volume of the main air intake area of ​​the air inlet grille, thereby ensuring that the air intake volume meets the standard.

[0034] In some embodiments of this application, a reinforcing portion 134 is provided at the location of the first reinforcing rib 131 and the second reinforcing rib 133 opposite to the air inlet 101. The reinforcing portion 134 is disposed on at least one side surface of the first reinforcing rib 131 and the second reinforcing rib 133 along the first direction Y. That is, the reinforcing portion 134 is provided on at least one side surface of the first reinforcing rib 131 along the first direction Y. For example, the reinforcing portion 134 can be provided on one side surface of the first reinforcing rib 131 along the first direction Y, or the reinforcing portion 134 can be provided on both sides surface of the first reinforcing rib 131 along the first direction Y. Similarly, the reinforcing portion 134 is provided on at least one side surface of the second reinforcing rib 133 along the first direction Y. For example, the reinforcing portion 134 can be provided on one side surface of the second reinforcing rib 133 along the first direction Y, or the reinforcing portion 134 can be provided on both sides surface of the second reinforcing rib 133 along the first direction Y.

[0035] It is understandable that stress concentration often leads to breakage at the locations where the first reinforcing rib 131 and the second reinforcing rib 133 face the air inlet 101. This application provides a reinforcing part 134 at the locations where the first reinforcing rib 131 and the second reinforcing rib 133 face the air inlet 101, which can evenly distribute the concentrated stress and make the locations where the first reinforcing rib 131 and the second reinforcing rib 133 face the air inlet 101 less prone to breakage. Furthermore, since the reinforcing part 134 is not located in the main air intake area in the middle of the air intake grille, the structure of the air intake grille can be made more stable and reliable without affecting the air intake volume.

[0036] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, a limiting rib 140 is provided on the leeward side of the grille bar 120. The limiting rib 140 has a limiting groove, and the reinforcing rib 130 is inserted into the limiting groove to limit the reinforcing rib 130 in the second direction X. By setting the limiting rib 140 to limit the reinforcing rib 130 in the second direction X, the reinforcing rib 130 of the air intake grille is not easily deformed, thus making the structure of the air intake grille more reliable.

[0037] This application also provides an air conditioner, which includes a casing and an air inlet grille. The specific structure of the air inlet grille is as described in the above embodiments. The casing has an air inlet, and the air inlet grille is located at the air inlet. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0038] Optionally, the air conditioner can be a window air conditioner, a wall-mounted air conditioner, or a floor-standing air conditioner.

[0039] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0040] The air intake grille and air conditioner provided in the embodiments of this application have been described in detail above. Specific examples have been used in this document to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
