Abstract

The application provides an air inlet component and an air conditioner. The air inlet component comprises air inlet baffles which are rotatably arranged at an air inlet of the air conditioner. The number of the air inlet baffles is more than two, and the air inlet baffles are arranged in sequence from one side of the air inlet to the other side of the air inlet. Each air inlet baffle is connected by a connecting rod. One of the air inlet baffles is a driving air inlet baffle, and the other air inlet baffles are driven air inlet baffles. The driving air inlet baffle drives the other driven air inlet baffles to rotate synchronously by the connecting rod. The connecting rod is flexibly connected with each air inlet baffle. The assembly of the driving air inlet baffle and the connecting rod satisfies that the driving air inlet baffle continues to rotate by a preset angle after driving the other driven air inlet baffles to close in place by the connecting rod, and then closes in place. According to the application, the risk that each air inlet baffle cannot close in place can be reduced, and abnormal sound can be reduced.

Description

Technical Field

[0001] This invention belongs to the field of air conditioning technology, specifically relating to an air intake component and an air conditioner. Background Technology

[0002] To address the issue of dust entering the air conditioner when it's not in use, a top air intake component is installed at the air inlet. When the air conditioner is in use, the top air intake opens to allow air in; when not in use, the air intake component closes to prevent dust from entering the air conditioner and affecting airflow and performance. The air intake component consists of multiple air intake baffles arranged in sequence. These baffles are driven by a motor and linked together to open and close. When closing, the drive motor directly closes the active air intake baffle, which is connected to other driven air intake baffles via a linkage, forming a parallel four-bar linkage that causes the driven air intake baffles to close together.

[0003] The aforementioned multiple air inlet baffles are rigidly connected by linkages to form a parallel four-bar linkage, which is driven by a drive motor. In actual operation, the following problems mainly occur: When the air inlet baffles are closed, because the air inlet baffles are rigidly linked by the parallel four-bar linkage, due to factors such as part tolerances and deformation, when one of the air inlet baffles closes to the position first (after reaching the material limit), the other air inlet baffles will stop moving, resulting in the other air inlet baffles not closing properly. Summary of the Invention

[0004] Therefore, the present invention provides an air intake component and an air conditioner, and the main technical problem to be solved is: how to reduce the risk that each air intake baffle cannot be closed in place.

[0005] To address the aforementioned problems, the present invention provides an air intake component, comprising an air intake baffle rotatably disposed at an air inlet of an air conditioner; the number of the air intake baffles is two or more, and they are arranged sequentially from one side of the air inlet to the other side; each of the air intake baffles is connected by a connecting rod; one of the air intake baffles is an active air intake baffle, and the other air intake baffles are driven air intake baffles; the active air intake baffle drives the other driven air intake baffles to rotate and open and close synchronously via the connecting rod;

[0006] The connecting rod is flexibly connected to each of the air inlet baffles; the assembly of the active air inlet baffle and the connecting rod satisfies the following condition: the active air inlet baffle closes to the position by driving the other driven air inlet baffles to close to the position through the connecting rod, and then continues to rotate by a preset angle to close to the position.

[0007] In some embodiments, the connecting rod and the air inlet baffle are flexibly connected by a flexible bushing assembly; wherein, the flexible bushing assembly includes an outer bushing, an inner bushing, and an elastic element; the inner bushing is sleeved inside the outer bushing, and the inner bushing is connected to the outer bushing through the elastic element;

[0008] The connecting rod is provided with a first connecting part, the air inlet baffle is provided with a second connecting part, and the flexible bushing assembly is sleeved on one of the first connecting part and the second connecting part through the outer bushing, and on the other of the first connecting part and the second connecting part through the inner bushing.

[0009] In some embodiments, the number of elastic elements is two or more, and they are evenly arranged around the circumference of the inner bushing.

[0010] In some embodiments, when the flexible bushing assembly is fitted onto the first connecting part through the inner bushing, the first connecting part is a protrusion provided on the connecting rod, the protrusion is provided with a hook, and the protrusion is hooked onto the inner bushing through the hook.

[0011] In some embodiments, the air intake component further includes a support rib; the support rib is disposed at the air conditioner air inlet to stop and limit the air intake baffle when the air intake baffle is closed and to provide support for the air intake baffle, and to separate from the air intake baffle when the air intake baffle is open.

[0012] In some embodiments, when the air inlet baffle is closed, the support rib and the air inlet baffle are in point contact.

[0013] In some embodiments, the air inlet baffle is rotatably disposed at the air inlet of the air conditioner via a pivot; the air inlet baffle has a first surface and a second surface facing each other; when the air inlet baffle is closed, the second surface is located inside the air inlet baffle relative to the first surface, and the support rib provides support to the air inlet baffle through the second surface;

[0014] Specifically, on the projection along the axis of the rotating shaft, when the air inlet baffle is closed, the line connecting the center of the rotating shaft and the shortest distance to the second surface is L1, the intersection of L1 and the second surface is A1, and the support point on the support rib that provides support for the air inlet baffle is B1; A1 and B1 do not coincide.

[0015] In some implementations, the distance d1 between A1 and B1 is 8 mm to 12 mm.

[0016] In some embodiments, each of the air inlet baffles is provided with a corresponding supporting rib;

[0017] Wherein, any two adjacent air inlet baffles are designated as air inlet baffle A and air inlet baffle B, and the supporting rib at air inlet baffle A is designated as supporting rib A, and the supporting rib at air inlet baffle B is designated as supporting rib B; there is a first interval between supporting rib A and supporting rib B, and when air inlet baffle A is opened, it rotates to the side of supporting rib A that is away from supporting rib B, and when air inlet baffle B is opened, it rotates to the first interval; wherein, the minimum distance d2 between air inlet baffle B and supporting rib A during rotation is 2 mm to 3 mm.

[0018] The present invention also provides an air conditioner comprising the air intake component described in any one of the above-mentioned embodiments.

[0019] The air intake component and air conditioner provided by this invention have the following beneficial effects:

[0020] 1. Since the active air intake baffle is the last to close, if one of the driven air intake baffles stops moving after reaching its position (e.g., being physically stopped by a limiting structure), but the active air intake baffle has not yet reached its limit point, the active air intake baffle can continue to rotate in the closing direction. Because the connecting rod is flexibly connected to each air intake baffle, the active air intake baffle can continue to drive the other unclosed driven air intake baffles to rotate through the connecting rod until all air intake baffles are closed. This reduces the risk that all air intake baffles may not close completely.

[0021] 2. By flexibly connecting the connecting rod to each air intake baffle, the flexible connection can buffer each air intake baffle during opening and closing, thereby effectively reducing abnormal noise when each air intake baffle reaches or leaves its physical limit.

[0022] 3. By setting multiple support ribs on the air conditioner panel, the air inlet baffle is limited by contact with the support ribs when it is closed. This avoids abnormal noise caused by the deformation of the middle of the air inlet baffle, and also avoids abnormal noise caused by the squeezing at the overlapping part of the inclined surface of the air inlet baffle.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0042] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0043] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0044] See also Figure 1-14 As shown, according to an embodiment of the present invention, an air intake component 100 is provided, which includes an air intake baffle 1, which is rotatably disposed at an air conditioning air intake 200. There are two or more air intake baffles 1, and each air intake baffle 1 is arranged sequentially along one side 2001 of the air conditioning air intake to the other side 2002 of the air conditioning air intake. For example, each air intake baffle 1 can be arranged sequentially along the width or length direction of the air conditioning air intake 200. Each air intake baffle 1 is connected by a connecting rod 2. One of the air intake baffles 1 is an active air intake baffle 11, and the other air intake baffles 1 are driven air intake baffles 122. The active air intake baffle 11 drives the other driven air intake baffles 122 to rotate and open synchronously via the connecting rod 2.

[0045] The aforementioned connecting rod 2 is flexibly connected to each air inlet baffle 1. The assembly of the active air inlet baffle 11 and the connecting rod 2 satisfies the following condition: the active air inlet baffle 11, after being driven to close into position by the connecting rod 2, continues to rotate by a preset angle to close into position.

[0046] In the above example, since the active air intake baffle is the last to close, when one of the driven air intake baffles stops moving after reaching its position (e.g., being physically stopped by a limiting structure), but the active air intake baffle has not yet reached its limit point, the active air intake baffle 11 can continue to rotate in the closing direction. Because the connecting rod 2 is flexibly connected to each air intake baffle 1, the active air intake baffle 11 can continue to drive the other unclosed driven air intake baffles to rotate through the connecting rod 2 until all air intake baffles are closed. This reduces the risk that each air intake baffle 1 may not close completely.

[0047] It should be noted that if the connection between the connecting rod 2 and each air inlet baffle 1 is rigid rather than flexible, then for the parallel four-bar linkage formed by the connecting rod 2 and the air inlet baffle 1, once any air inlet baffle 1 reaches the material limit, the other air inlet baffles 1 will stop moving. Furthermore, because the air inlet baffles 1 are rigidly connected, when they open and close, the high speed of the air inlet baffles 1 can easily cause impact or slapping noises. Also, when the air inlet baffles 1 open and close, the overlapping inclined surfaces of adjacent air inlet baffles 1 can easily deform and cause noise due to compression. In this invention, by making the connecting rod 2 and each air inlet baffle 1 flexibly connected, the flexible connection can buffer the air inlet baffles 1 during opening and closing, effectively reducing noise when they reach or leave their physical limits.

[0048] In this configuration, any two adjacent air inlet baffles 1 are connected by a connecting rod 2 to form a parallel four-bar linkage. Therefore, when the active air inlet baffle 11 rotates, it can drive the other driven air inlet baffles 122 to rotate and open synchronously via the connecting rod 2. The connecting rod 2 can be a split structure or a one-piece structure. When the connecting rod 2 is a split structure, if there are three or more air inlet baffles 1, each pair of adjacent air inlet baffles 1 is connected by different parts of the connecting rod 2. When the connecting rod 2 is a one-piece structure, if there are three or more air inlet baffles 1, each pair of adjacent air inlet baffles 1 is connected by different segments on the connecting rod 2.

[0049] To meet the assembly requirements of the active air intake baffle 11 and the connecting rod 2, the active air intake must rotate a preset angle after the other driven air intake baffles 122 have closed to their positions via the connecting rod 2 before finally closing completely. Specifically, the connection between the active air intake baffle 11 and the connecting rod 2, such as the connecting hole, requires eccentric adjustment. This means that after all the driven air intake baffles 122 have theoretically closed to their positions, the active air intake baffle 11 has not yet theoretically closed to its position. This unclosed angle, typically the aforementioned preset angle, is 3 degrees. This ensures that, under the influence of tolerances and deformation, the active air intake baffle 11 is the last to close to its position.

[0050] For ease of understanding, we will not consider factors such as part deformation, part dimensional tolerances, and movement play. Figure 2 As shown, the active air intake baffle 11 and the driven air intake baffle 12 are theoretically fully closed, and all air intake baffles 1 are flush in appearance. This state is used as a reference. Figure 4 As shown, the active air intake baffle 11 is eccentrically positioned relative to... Figure 1 In other words, when the driven air intake baffle 12 is fully closed in theory, the active air intake baffle 11 is not fully closed in theory. The active air intake baffle 11, relative to... Figure 1 The device is in the closed position, but it is still missing a preset angle, such as 3 degrees.

[0051] The purpose of the eccentric treatment of the active air intake baffle 11 is to ensure that the active air intake baffle 11 is the last of all air intake baffles 1 to close completely. If the active air intake baffle 11 closes completely in advance, and one or more of the other driven air intake baffles 12 are not closed completely, the active air intake baffle 11 will be physically limited by contact with the limiting structure, and the drive motor 3 will stall. The torque of the active air intake baffle 11 will not be transmitted to the driven air intake baffles 12, and the driven air intake baffles 12 that are not closed will not continue to close completely.

[0052] Active air intake baffle 11 Figure 4 After the eccentric adjustment, the active air intake baffle 11 is the last to close completely. When one of the driven air intake baffles 12 stops moving after being physically stopped by the limiting structure, but the active air intake baffle 11 has not reached the limiting point, it continues to rotate in the closing direction under the action of the drive motor 3. Because the connecting rod 2 is flexibly connected to each air intake baffle 1, the connecting rod 2 can continue to move to drive the other unclosed driven air intake baffles 12 to move until all air intake baffles 1 are closed completely.

[0053] To achieve the aforementioned technical effect of flexible connection between the connecting rod 2 and the air inlet baffle 1, in some embodiments, such as Figure 5 As shown, the aforementioned connecting rod 2 and the air inlet baffle 1 are flexibly connected via a flexible bushing assembly 4. The flexible bushing assembly 4 includes an outer bushing 41, an inner bushing 42, and an elastic element 43. The inner bushing 42 is fitted inside the outer bushing 41 and is connected to the outer bushing 41 via the elastic element 43. The connecting rod 2 has a first connecting portion 21, and the air inlet baffle 1 has a second connecting portion 101. The flexible bushing assembly 4 is fitted onto one of the first connecting portion 21 and the second connecting portion 101 via the outer bushing 41, and onto the other of the first connecting portion 21 and the second connecting portion 101 via the inner bushing 42.

[0054] In the above example, since the inner bushing 42 and the outer bushing 41 are connected by the elastic element 43, the inner bushing 42 and the outer bushing 41 can move relative to each other. Thus, the connecting rod 2 and the air inlet baffle 1, which are respectively connected to the inner bushing 42 and the outer bushing 41, can also move relative to each other at the flexible bushing assembly 4, thereby achieving the technical effect of flexible connection between the connecting rod 2 and the air inlet baffle 1.

[0055] The inner bushing 42 and the outer bushing 41 can have a certain relative movement, which is generally 1-3mm. Specifically, by adding a flexible bushing assembly 4 at the connection between the air inlet baffle 1 and the connecting rod 2, during movement, the drive motor 3 drives the active air inlet baffle 11 to rotate. The active air inlet baffle 11 is connected to the connecting rod 2 via the flexible bushing assembly 4, and the connecting rod 2 is then connected to the driven air inlet baffle 122 via the flexible bushing assembly 4, thereby driving the driven air inlet baffle 122 to move.

[0056] In some implementations, such as Figure 8-9 As shown, the aforementioned elastic elements 43 can be two or more, and are evenly arranged around the circumference of the inner bushing 42, which can improve the stability of the connection between the inner bushing 42 and the outer bushing 41. In a specific application example, the number of elastic elements 43 is eight.

[0057] like Figure 8-9 As shown, the elastic element 43 can be a spring, rubber band, or other elastic material. The elastic element 43 is disposed between the inner bushing 42 and the outer bushing 41. One end of the elastic element 43 is connected to the inner bushing 42, and the other end is connected to the outer bushing 41.

[0058] In a specific application example, such as Figure 6 As shown, when the flexible bushing assembly 4 is fitted onto the first connecting part 21 through the inner bushing 42, the first connecting part 21 can be a protrusion provided on the connecting rod 2. The protrusion is provided with a hook 22, and the protrusion is hooked onto the inner bushing 42 through the hook 22 to prevent the protrusion from detaching from the inner bushing 42. This can improve the connection stability between the protrusion and the inner bushing 42.

[0059] Among them, such as Figure 6 As shown, each of the aforementioned air inlet baffles 1 is equipped with a rotating shaft 120, and each air inlet baffle 1 rotates via its respective rotating shaft 120. The rotating shaft 120 of each air inlet baffle 1 is connected to the air conditioner housing, and each air inlet baffle 1 opens and closes around its respective rotating shaft 120. The rotating shaft 120 of the active air inlet baffle 11 is connected to a drive motor 3, and the active air inlet baffle 11 is used to rotate under the drive of the drive motor 3. The second connecting portion 101 on each air inlet baffle 1 is a drive hole.

[0060] like Figure 5As shown, the assembly process of the air inlet baffle 1 with the connecting rod 2 via the flexible bushing assembly 4 is as follows: The flexible bushing assembly 4 is first fitted into the drive hole of the air inlet baffle 1 via the outer bushing 41, and then the protrusion on the connecting rod 2 is inserted into the inner bushing 42 of the bushing assembly. The protrusion and the inner bushing 42 can be rotatably engaged. The centerlines of the flexible bushing assembly 4, the drive hole, and the connecting rod 2 can coincide.

[0061] In some implementations, the aforementioned preset angle can be 2 to 4 degrees. Preferably, the preset angle is 3 degrees.

[0062] In some implementations, such as Figure 10-14 As shown, the aforementioned air intake component 100 may further include a support rib 5. The support rib 5 is used to be installed at the air conditioning air intake 200. When the air intake baffle 1 is closed, the support rib 5 stops and limits the air intake baffle 1 and provides support for the air intake baffle 1. When the air intake baffle 1 is open, the support rib 5 separates from the air intake baffle 1 to reduce the friction between the support rib 5 and the air intake baffle 1.

[0063] In the above example, the air inlet baffle 1 is closed in place by the physical limitation of the support rib 5, avoiding the limitation by the inclined surface of the adjacent air inlet baffle 1, thus avoiding squeezing noise caused by the deformation or collapse of the inclined surface.

[0064] During the closing process of the air inlet baffle 1, the air inlet baffle 1 and the support rib 5 are separate. The air inlet baffle 1 only comes into contact with the support rib 5 at the moment of closing, which can avoid abnormal noise during the movement.

[0065] In some embodiments, the aforementioned support ribs 5 can be provided on the panel of the air conditioner. Multiple support ribs 5 can be provided at each air inlet baffle 1, meaning that each air inlet baffle 1 is stopped and supported by multiple support ribs 5 when closed. The support ribs 5 providing support for the same air inlet baffle 1 form a support rib group. Each support rib 5 within the support rib group is arranged sequentially at intervals along the length of the corresponding air inlet baffle 1 to jointly provide support for the air inlet baffle 1 when closed, preventing the air inlet baffle 1 from collapsing and deforming, which could cause abnormal noise.

[0066] In some implementations, such as Figure 10 As shown, the aforementioned air inlet baffles 1 are arranged sequentially along the width direction of the air conditioning inlet 200, and the number of air inlet baffles 1 is N, where N is a positive integer greater than or equal to 2. The aforementioned air inlet component 100 also includes a support rib row 6, on which N aforementioned support ribs 5 are provided, and these N support ribs 5 are used to provide support for each air inlet baffle 1 in a one-to-one correspondence.

[0067] In some implementations, such as Figure 12As shown, when the air inlet baffle 1 is closed, the support rib 5 and the air inlet baffle 1 are in point contact. This avoids abnormal noise caused by the deformation of the middle of the air inlet baffle 1, and also avoids abnormal noise caused by the squeezing at the overlapping part of the inclined surface of the air inlet baffle 1.

[0068] The top of the support rib 5 can be arc-shaped to facilitate point contact between the support rib 5 and the air inlet baffle 1 when the air inlet baffle 1 is closed.

[0069] In some embodiments, the aforementioned air inlet baffle 1 is rotatably mounted at the air inlet 200 of the air conditioner via a pivot 120. Each air inlet baffle 1 may have two or more pivots 120 arranged coaxially. Preferably, each air inlet baffle 1 may have three pivots 120 arranged coaxially, with these three pivots 120 spaced apart along the length of the air inlet baffle 1, and respectively located at the middle and both ends of the length of the air inlet baffle 1. This improves the stability of the air inlet baffle 1 when each pivot 120 is connected to the air conditioner housing.

[0070] like Figure 10 As shown, the aforementioned pivot 120 located in the middle of the air inlet baffle 1 is taken as the intermediate pivot 121. Since the middle of the air inlet 200 is not the middle of the entire air conditioner, the span of the air inlet baffle 1 on the left side of the intermediate pivot 121 is smaller than the span on the right side. Therefore, two support ribs 6 can be set on one side of the air inlet baffle 1, such as the left side, and three support ribs 6 can be set on the other side of the air inlet baffle 1, such as the right side.

[0071] like Figure 12 As shown, the aforementioned air inlet baffle 1 has a first surface 10a and a second surface 10b facing each other. When the air inlet baffle 1 is closed, the second surface 10b is located inside the air inlet baffle 1 relative to the first surface 10a, and the support rib 5 provides support to the air inlet baffle 1 through the second surface 10b. Specifically, in the projection along the axial direction of the rotating shaft 120, when the air inlet baffle 1 is closed, the line connecting the center of the rotating shaft 120 and the shortest distance to the second surface 10b is L1, the intersection of L1 and the second surface 10b is A1, and the support point on the support rib 5 that provides support to the air inlet baffle 1 is B1; A1 and B1 do not coincide.

[0072] In the example above, because the support points B1 and A1 do not coincide, when the air inlet baffle 1 is opened, the support points on the support rib 5 can be quickly separated, thus avoiding friction noise between the air inlet baffle 1 and the support rib 5.

[0073] It should be noted that if the support points B1 and A1 on the support rib 5 coincide, then when the air inlet baffle 1 is opened, the air inlet baffle 1 and the support rib 5 will separate slowly. During this slow separation process, because the air inlet baffle 1 is slumped down due to gravity, the support points will rotate and be squeezed, producing abnormal noise.

[0074] Specifically, the distance between support points B1 and A1 on the support rib 5 needs to be moderate. If this distance is too small, the air inlet baffle 1 cannot quickly separate from the support point on the support rib 5 when it opens, which can easily cause abnormal noise. However, if this distance is too large, the movement trajectory of an adjacent air inlet baffle 1 will interfere with the support rib 5. Preferably, the distance d1 between A1 and B1 is 8 mm to 12 mm.

[0075] In some implementations, such as Figure 14 As shown, each of the aforementioned air inlet baffles 1 is provided with the aforementioned support rib 5. For ease of description, any two adjacent air inlet baffles 1 are taken as air inlet baffle A 1a and air inlet baffle B 1b, and the support rib 5 at air inlet baffle A 1a is taken as support rib A 51. Support rib A 51 is used to stop and limit air inlet baffle A 1a when it is closed and to provide support for air inlet baffle A 1a. Support rib A 51 separates from air inlet baffle A 1a when it is open. The support at air inlet baffle B 1b is taken as support rib B 52. Support rib B 52 is used to stop and limit air inlet baffle B 1b when it is closed and to provide support for air inlet baffle B 1b. Support rib B 52 separates from air inlet baffle B 1b when it is open.

[0076] There is a first gap 50 between support rib A 51 and support rib B 52. When the air inlet baffle A 1a is opened, it rotates to the side of support rib A 51 opposite to support rib B 52, and when the air inlet baffle B 1b is opened, it rotates into the first gap 50. The minimum distance d2 between air inlet baffle B 1b and support rib A 51 during rotation is 2 mm to 3 mm.

[0077] In the above example, by leaving a 2-3 mm movement gap between the air inlet baffle 1 and the adjacent support rib 5, interference between the movement trajectory of the air inlet baffle 1 and the adjacent support rib 5 can be effectively prevented.

[0078] In a specific application example, the number of the aforementioned air intake baffles 1 can be six. The aforementioned air intake component 100 also includes a drive motor 3, and the aforementioned active air intake baffles 11 are driven to rotate by the drive motor 3. The air intake baffles 1 are arranged sequentially, with adjacent air intake baffles 1 overlapping at an angle, forming an outer surface when closed to prevent external dust from entering the air conditioning inlet 200. When closed, the drive motor 3 drives the active air intake baffles 11 to close directly. The active air intake baffles 11 are connected to other driven air intake baffles 12 via connecting rods 2, forming a parallel four-bar linkage, thereby causing the driven air intake baffles 12 to move and close together. In this example, the active air intake baffles 11 are closed when the drive motor 3 drives them to rotate clockwise. When open, the drive motor 3 drives the active air intake baffles 11 to rotate counterclockwise.

[0079] The present invention also provides an air conditioner that may include the air intake component 100 of any of the above-mentioned methods. Because the air conditioner uses the air intake component 100, the risk that each air intake baffle 1 may not close completely is reduced, and abnormal noise is also reduced.

[0080] In some implementations, the aforementioned air conditioner may be a split-type air conditioner.

[0081] In this invention, the air intake component 100, by adding a flexible bushing assembly 4 at the connection between the air intake baffle 1 and the connecting rod 2, enables multiple air intake baffles 1 to close completely, while also increasing buffering and reducing abnormal noise. Furthermore, by providing multiple support ribs 5 on the air conditioner's panel, the air intake baffle 1 makes point contact with the support ribs 5 when closed, preventing abnormal noise caused by deformation and sagging in the middle of the air intake baffle 1, and also preventing abnormal noise caused by squeezing at the overlapping angles of the air intake baffle 1. This solves the technical problem in the prior art where, due to the linkage via the connecting rod 2, multiple air intake baffles 1 cannot all close completely when closed, and also solves the technical problem that squeezing at the overlapping angles of the air intake baffle 1 easily generates abnormal noise when opening and closing.

[0082] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0083] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
