Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a dustproof mechanism and an air conditioner. Background Technology

[0002] An air conditioner is a device that draws in and processes the air around it. It typically operates in an enclosed indoor area or environment and can perform functions such as cooling, heating, dehumidification, defrosting, and fan operation, thereby improving the user's living or working environment.

[0003] However, after prolonged use, the air inlet of an air conditioner remains open, allowing a large amount of dust to enter the unit and making it difficult to clean. If the air conditioner continues to run, it will blow the dust into the room, reducing indoor air quality and affecting the user experience.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] To address at least one of the aforementioned problems in the prior art, namely, to resolve the issue of reduced air quality and negative user experience caused by open air inlets in existing air conditioners, this application provides a dustproof mechanism, comprising:

[0006] An air inlet frame is provided at the air inlet of the air conditioner;

[0007] A sway vane assembly, comprising an active sway vane and a driven sway vane, both sides of which are rotatably connected to the air inlet frame;

[0008] A drive assembly is disposed on the air inlet frame and connected to the active oscillating blade, the drive assembly being capable of driving the active oscillating blade to rotate;

[0009] The connecting rod connects both the active and passive pendulum blades, enabling the passive and active pendulum blades to move in tandem.

[0010] With the above technical solution, the dust prevention mechanism can be set at the air inlet of the air conditioner. When the air conditioner is turned on, the active swing blades can be driven to rotate by the drive component. At this time, the driven swing blades and the active swing blades can rotate synchronously through the connecting rod, so that the air inlet of the air conditioner is in an open state. When the air conditioner is turned off, the active swing blades can be driven to rotate in the opposite direction to close the air inlet of the air conditioner, thereby preventing dust from entering the air conditioner when it is not running and improving the user experience.

[0011] In the preferred technical solution of the above dust prevention mechanism, the ends of the active swing blade and the driven swing blade are provided with connecting plates, and each connecting plate is provided with a connecting shaft. The connecting shaft located on the driven swing blade is rotatably connected to the air inlet frame.

[0012] An output shaft hole is provided at the end of the connecting shaft located on the active swing blade, and the output shaft of the drive assembly is fixedly connected to the output shaft hole.

[0013] In the preferred embodiment of the dustproof mechanism described above, each connecting plate is provided with a flip shaft hole, and the connecting rod is provided with a flip shaft corresponding to the flip shaft hole. The flip shaft passes through the flip shaft hole so that the connecting rod and the connecting plate are rotatably connected.

[0014] In the preferred embodiment of the above dustproof mechanism, each of the connecting plates is provided with a toothed structure, and the connecting rod is provided with a rack. Each of the connecting plates and the connecting rod are connected to the rack through the toothed structure.

[0015] The air inlet frame is equipped with a slide rail, and the connecting rod can move linearly along the slide rail.

[0016] In the preferred embodiment of the above dustproof mechanism, the connecting rod is located on the side of the connecting plate away from the oscillating blade assembly in the height direction, and the tooth structure and the rack are arranged opposite to each other along the height direction; and / or

[0017] The connecting rod has multiple protrusions on both sides, and these protrusions abut against the slide rail, allowing them to move linearly along the slide rail; and / or

[0018] The slide rail is equipped with a baffle.

[0019] In the preferred embodiment of the dustproof mechanism described above, there are two connecting rods, and each side of the active swing blade and the driven swing blade is connected to one of the connecting rods.

[0020] By adopting the above technical solution, the stability of the oscillating blade assembly during rotation can be increased.

[0021] In the preferred embodiment of the dustproof mechanism described above, a stabilizing plate is provided in the middle of both the active and driven blades, a support member is provided in the middle of the air inlet frame, and a rotating shaft corresponding to the stabilizing plate is provided on the support member, with each stabilizing plate rotatably connected to the corresponding rotating shaft.

[0022] In the preferred embodiment of the dustproof mechanism described above, the support member includes two support plates arranged along the width direction of the swing blade assembly, and both sides of each rotating shaft are connected to the two support plates. A self-rotation notch is formed on the stabilizing plate, and the rotating shaft is engaged with the self-rotation notch.

[0023] Multiple clearance notches are formed on the two support plates, which provide space when the active blade and the driven blade rotate.

[0024] By adopting the above technical solution, the stability of the oscillating blade assembly during rotation can be further increased.

[0025] In the preferred embodiment of the dustproof mechanism described above, the cross-sectional shape of both the active and driven blades is set to a parallelogram.

[0026] When using the above technical solution, since a gap needs to be left between two adjacent blades, setting the cross-sectional shape of each blade to a parallelogram can prevent interference between the blades during rotation while maintaining the gap. Furthermore, the inclined surface of the blade can serve as a positioning surface when the blade closes, resulting in a smoother appearance after closure and reducing dust ingress.

[0027] This application also provides an air conditioner that includes a dustproof mechanism as described in any of the preceding claims.

[0028] With the aforementioned dustproof mechanism, when the air conditioner is turned on, the dustproof mechanism keeps the air inlet of the air conditioner open, and when the air conditioner is turned off, it keeps the air inlet closed, thereby preventing dust from entering the air conditioner when it is not running and improving the user experience.

[0040] Preferred embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application. For example, although the oscillating vane assembly in the drawings includes one active oscillating vane and three driven oscillating vanes, this arrangement is not mandatory. Those skilled in the art can determine the number of driven oscillating vanes based on the size of the air inlet of the air conditioner and the size of each oscillating vane.

[0041] It should be noted that in the description of this application, the terms "upper," "lower," "left," "right," "inner," and "outer," which indicate directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, in the description of this application, "a plurality of" refers to at least two.

[0042] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] As described in the background section, an air conditioner is a device that draws in and processes the air around it. It typically operates in an enclosed indoor area or environment and can perform functions such as cooling, heating, dehumidification, defrosting, and fan operation, thereby improving the user's living or working environment.

[0044] However, after prolonged use, the air inlet of an air conditioner remains open, allowing a large amount of dust to enter the unit and making it difficult to clean. If the air conditioner continues to run, it will blow the dust into the room, reducing indoor air quality and affecting the user experience.

[0045] To address the issue of reduced air quality and negative user experience caused by open air inlets in existing air conditioners, this application provides a dustproof mechanism, including an air inlet frame, a swivel blade assembly, a drive assembly, and a connecting rod. The air inlet frame is located at the air inlet of the air conditioner. The swivel blade assembly includes an active swivel blade and a driven swivel blade, both sides of which are rotatably connected to the air inlet frame. The drive assembly is located in the air inlet frame and connected to the active swivel blade, enabling the drive assembly to drive the active swivel blade to rotate. Both the active and driven swivel blades are connected to the connecting rod, which allows the driven swivel blade to move in tandem with the active swivel blade.

[0046] With the above technical solution, the dust prevention mechanism can be set at the air inlet of the air conditioner. When the air conditioner is turned on, the active swing blades can be driven to rotate by the drive component. At this time, the driven swing blades and the active swing blades can rotate synchronously through the connecting rod, so that the air inlet of the air conditioner is in an open state. When the air conditioner is turned off, the active swing blades can be driven to rotate in the opposite direction to close the air inlet of the air conditioner, thereby preventing dust from entering the air conditioner when it is not running and improving the user experience.

[0047] The following reference Figures 1 to 5 The dustproof mechanism of this application is described. Among other things, Figure 1 This is an external structural diagram of the dustproof mechanism of this application; Figure 2 This is a structural diagram of the air inlet frame according to one embodiment of this application; Figure 3 This is a schematic diagram of the drive mechanism of a leaf assembly according to an embodiment of this application;

[0048] Figure 4 This is an internal structural diagram of a dustproof mechanism according to an embodiment of this application; Figure 5 This is a schematic diagram showing the connection between the support component and the stabilizing plate in this application.

[0049] like Figures 1 to 5As shown, in a preferred embodiment, the dustproof mechanism includes an air inlet frame 1, a swivel assembly 2, a drive assembly 3, and a connecting rod 4. The air inlet frame 1 can be disposed at the air inlet of the air conditioner. The swivel assembly 2 includes one active swivel 21 and three passive swivels 22. Both sides of the active swivel 21 and the passive swivels 22 are rotatably connected to the air inlet frame 1, and the cross-sectional shape of the active swivel 21 and the passive swivels 22 is set as a parallelogram. The drive assembly 3 is disposed on the air inlet frame 1 and is connected to the active swivel 21, and the drive assembly 3 can drive the active swivel 21 to rotate.

[0050] There are two connecting rods 4. Each side of the active oscillating blade 21 and the driven oscillating blade 22 is connected to a connecting rod 4, enabling the driven oscillating blade 22 to move in tandem with the active oscillating blade 21. Connecting plates 5 are provided at both ends of the active oscillating blade 21 and the driven oscillating blade 22. Each connecting plate 5 has a connecting shaft 51. Correspondingly, the air inlet frame 1 has connecting shaft holes. Each connecting shaft 51 can pass through the corresponding connecting shaft hole. The connecting shafts 51 on both sides of the driven oscillating blade 22 are rotatably connected to the air inlet frame 1 after passing through the corresponding connecting shaft holes. The end of the connecting shaft 51 on one side of the active oscillating blade 21 has an output shaft hole. The output shaft of the drive assembly 3 is fixedly connected to the output shaft hole, while the connecting shaft 51 on the other side of the active oscillating blade 21 is rotatably connected to the air inlet frame 1 after passing through the corresponding connecting shaft hole. Each connecting plate 5 has a flip shaft hole, and the connecting rod 4 is provided with a flip shaft 41 corresponding to the flip shaft hole. The flip shaft 41 passes through the flip shaft hole so that the connecting rod 4 and the connecting plate 5 can be rotatably connected.

[0051] Both the active blade 21 and the driven blade 22 have a stabilizing plate 6 at their center. Correspondingly, the air inlet frame 1 has a support member 13 at its center. The support member 13 has a rotating shaft 131 corresponding to the stabilizing plate 6, and each stabilizing plate 6 is rotatably connected to its corresponding rotating shaft 131. Specifically, the support member 13 includes two support plates 132 arranged along the width direction of the blade assembly 2. Both sides of each rotating shaft 131 are fixedly connected to the two support plates 132. The stabilizing plate 6 has a rotation notch, and the rotating shaft 131 is engaged with the rotation notch. The two support plates 132 have multiple clearance notches, which provide space when the active blade 21 and the driven blade 22 rotate.

[0052] See below. Figures 3 to 5 The driving principle of the oscillating blade assembly 2 in this embodiment will be introduced, such as... Figure 3 and Figure 4 As shown, at this time, the louver assembly 2 is in the same plane so that the air inlet of the air conditioner is in the closed state. When the air conditioner is turned on, it is so that... Figure 3 and Figure 4Taking the left-viewing direction as an example, the active pendulum 21 can be controlled to rotate counterclockwise around the output shaft of the drive component 3 by the drive component 3. At this time, the connecting plate 5 on the active pendulum 21 rotates counterclockwise, which will drive the connecting rod 4 to move away from the active pendulum 21. Since the connecting plates 5 on the three driven pendulums 22 are all connected to the flipping shaft 41 on the connecting rod 4, the movement of the connecting rod 4 will drive the three driven pendulums 22 to rotate counterclockwise, thereby realizing the linkage effect between the active pendulum 21 and the driven pendulum 22. Moreover, the linkage effect brought by the connecting rods 4 on the left and right sides is consistent. In this embodiment, the drive component 3 is not provided on the right side of the active pendulum 21. At this time, the two connecting rods 4 on the left and right sides can avoid the situation of inconsistency between the left and right sides when the pendulum component 2 flips.

[0053] Furthermore, to ensure the synchronous rotation of the oscillating blade assembly 2, a stabilizing plate 6 is provided in the middle of both the active oscillating blade 21 and the driven oscillating blade 22. The stabilizing plate 6 is rotatably connected to the rotating shaft 131, and each rotating shaft 131 is coaxial with the connecting shaft 51 on the corresponding connecting plate 5. Figure 5 As shown, the stabilizing plate 6 has a rotation notch to allow for rotation. Figure 5 Taking the direction shown as an example, the size above the rotation notch is slightly smaller than the size of the rotating shaft 131, so that the rotating shaft 131 can be engaged in the rotation notch set on the stabilizing plate 6 from above. In the direction shown in 5, the blade assembly 2 rotates clockwise, and during the rotation, the rotating shaft 131 is always engaged with the rotation notch of the stabilizing plate 6, and the support plate 132 has an avoidance notch, which can prevent the blade assembly 2 from interfering with the support plate 132 during the rotation.

[0054] It should be explained that the driving principle of the oscillating leaf assembly 2 is not fixed, as will be discussed below. Figures 6 to 8 Let's introduce another type of dust control mechanism. Among them, Figure 6 This is a structural diagram of the air inlet frame according to another embodiment of this application; Figure 7 This is a schematic diagram of the drive mechanism of the leaf assembly according to another embodiment of this application; Figure 8 This is an internal structural diagram of a dustproof mechanism according to another embodiment of this application.

[0055] like Figures 6 to 8 As shown, in another preferred embodiment, the basic structure of the dustproof mechanism is basically the same as that of the previous embodiment, but in this embodiment, it is based on... Figure 7Taking the direction shown as an example, each connecting plate 5 has an incomplete tooth structure 52 on its upper side, and a rack 42 is provided at the bottom of the connecting rod 4. Each connecting plate 5 and the connecting rod 4 are connected by meshing the tooth structure 52 and the rack 42. The air inlet frame 1 is provided with a slide rail 11, and the connecting rod 4 is placed in the slide rail 11. There are four protrusions 43 on each side of the connecting rod 4. The bottom of the protrusions 43 on both sides abuts against the slide rail 11. That is to say, the connecting rod 4 is hung on the slide rail 11 through the protrusions 43 on both sides. The bottom of the protrusions 43 on both sides can move linearly along the slide rail 11, that is, the connecting rod 4 can move linearly along the slide rail 11. A baffle 12 is provided on the slide rail 11.

[0056] See below. Figure 7 The driving principle of the oscillating blade assembly 2 in this embodiment will be introduced to illustrate this principle. Figure 7 Taking the left-viewing direction as an example, the active oscillating blade 21 can be controlled to rotate counterclockwise around the output shaft of the drive component 3 by the drive component 3. At this time, the connecting plate 5 on the active oscillating blade 21 rotates counterclockwise. Since the tooth structure 52 on the active oscillating blade 21 is meshed with the rack 42, the connecting rod 4 will move away from the active oscillating blade 21. Since the connecting plates 5 on the three driven oscillating blades 22 are all meshed with the connecting rod 4, the movement of the connecting rod 4 will drive the three driven oscillating blades 22 to rotate counterclockwise, thereby achieving the effect of linkage between the active oscillating blade 21 and the driven oscillating blades 22.

[0057] Those skilled in the art will understand that although connecting plates 5 are provided on both sides of the oscillating blade assembly 2 in this application, and the connecting plates 5 on the same side are all connected to a connecting rod 4 to ensure that the oscillating blade assembly 2 can rotate synchronously, their arrangement is not fixed. In an alternative embodiment, when the length of the oscillating blade assembly 2 is short, a connecting plate 5 can be provided only on one side of the oscillating blade assembly 2. In this case, only one connecting rod 4 is provided, and each connecting plate 5 is connected to the connecting rod 4, while the other side of the oscillating blade assembly 2 is directly and rotatably connected to the air inlet frame 1. In addition, the connection method between the connecting plate 5 and the connecting rod 4 is not fixed. In an alternative embodiment, a flipping shaft can be provided on the connecting plate 5, and a flipping shaft hole can be opened on the connecting rod 4 accordingly, which can also achieve a rotatable connection between the connecting plate 5 and the connecting rod 4. Furthermore, the configuration of the drive component 3 is not fixed. In an alternative embodiment, when the length of the oscillating blade component 2 is long, the two sides of the active oscillating blade 21 can be connected to a drive component 3 respectively, and the synchronous flipping of the two sides of the active oscillating blade 21 can be achieved through the two drive components 3, so as to avoid the twisting of each oscillating blade during the flipping.

[0058] Those skilled in the art will also understand that, in the embodiment where the connecting plate 5 and the connecting rod 4 are meshed, the toothed structure 52 on the connecting plate 5 and the rack 42 on the connecting rod 4 are arranged opposite each other along the height direction of the connecting plate 5. However, their arrangement is not fixed and can be modified according to requirements, as long as it does not hinder the normal rotation of the oscillating blade assembly 2. In an alternative embodiment, the toothed structure 52 on the connecting plate 5 and the rack 42 on the connecting rod 4 can be arranged opposite each other along the length direction of the oscillating blade assembly 2, that is, with Figure 7 Taking the direction shown as an example, a toothed structure 52 can be provided on the right side of the connecting plate 5. At this time, the connecting rod 4 is located on the right side of the connecting plate 5, and a rack 42 is provided on the left side of the connecting rod 4, which can also achieve the meshing connection between the connecting plate 5 and the connecting rod 4. In addition, in this embodiment, the setting of the protrusions 43 on both sides of the connecting rod 4 is not necessary. Those skilled in the art can change the number of protrusions 43 on both sides of the connecting rod 4 or the connection method between the connecting rod 4 and the slide rail 11 as needed, as long as it does not affect the normal function of the connecting rod 4. For example, the slide rail 11 can be set on the left side of the connecting rod 4, with the left side of the connecting rod 4 extending into the slide rail 11, and the linear movement of the connecting rod 4 is completed by the slider guide rail. At this time, the setting of the baffle 12 on the slide rail 11 is not necessary, as long as it can ensure that the connecting rod 4 cannot fall off the slide rail 11.

[0059] It should be explained that in this application, because the length of the oscillating blade assembly 2 is relatively long, its strength is insufficient during rotation, making it prone to twisting. The stability plate 6 and the support member 13 can increase the stability of the oscillating blade assembly 2 during rotation, but their arrangement is not fixed. In an alternative embodiment, when the length of the oscillating blade assembly 2 is short, the support member 13 on the air inlet frame 1 and the stability plate 6 on the oscillating blade assembly 2 can be omitted. In another alternative embodiment, when the stability plate 6 is provided, the specific arrangement of the support member 13 and the stability plate 6 can be changed. For example, only one support plate 132 can be provided, and one side of the rotating shaft 131 can be fixedly connected to the support plate 132. Of course, in this case, the rotation notch on the stability plate 6 can also be omitted, and a rotating shaft hole can be opened on the stability plate 6, through which the rotating shaft 131 can pass, thereby achieving a rotatable connection between the stability plate 6 and the rotating shaft 131. In addition, in this embodiment, the rotation angle of each blade is 90 degrees. In addition to preventing interference between the support plate 132 and the blade assembly 2 during rotation, the clearance notch can also limit the rotation angle of each blade when it rotates. However, the clearance notch on the support plate 132 is not fixed. Those skilled in the art can change the shape of the clearance notch according to their needs, as long as it does not hinder the normal rotation of each blade.

[0060] It should also be explained that, since a gap needs to be left between two adjacent blades, in this embodiment, setting the cross-sectional shape of each blade to a parallelogram can prevent interference between the blades during rotation while maintaining the gap. Furthermore, the inclined surface of the blade can serve as a positioning surface when the blade closes, making the appearance smoother after closure and reducing dust entry. However, this setting is not mandatory; those skilled in the art can change the cross-sectional shape of each blade as needed, as long as it does not affect the normal function of the dustproof mechanism. Additionally, although the blade assembly 2 in this embodiment includes one active blade 21 and three driven blades 22, their arrangement is not mandatory. Those skilled in the art can determine the number of driven blades 22 based on the size of the air inlet of the air conditioner and the size of each blade.

[0061] This application also provides an air conditioner that includes any of the dustproof mechanisms described above.

[0062] With the aforementioned dustproof mechanism, when the air conditioner is turned on, the dustproof mechanism keeps the air inlet of the air conditioner open, and when the air conditioner is turned off, it keeps the air inlet closed, thereby preventing dust from entering the air conditioner when it is not running and improving the user experience.

[0063] Those skilled in the art will understand that although some embodiments described herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this application and form different embodiments. For example, any of the claimed embodiments in the claims of this application can be used in any combination.

[0064] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
