Description

Technical Field

[0001] This application relates to the field of air conditioner technology, specifically to a filter dust removal device for an air conditioner and an air conditioner. Background Technology

[0002] Currently, air conditioners continuously draw in indoor air during operation and filter it through a filter. During this process, tiny particles such as dust, hair, and dander are trapped by the filter and accumulate there. If the filter is not cleaned for a long time, these particles will build up, forming a layer of grime. This not only reduces the filter's filtration performance but may also cause the accumulated particles to be blown back into the room during air conditioning operation, leading to decreased indoor air quality and respiratory discomfort.

[0003] To achieve automatic dust removal from filter screens, a filter screen dust removal mechanism has been disclosed. This mechanism includes a winding device and an unfolding device for winding and unfolding the filter screen, respectively. The winding device is equipped with a dust removal section, which removes dust from the filter screen during winding and / or unfolding. The winding device includes a winding shaft, and the unfolding device includes an unfolding shaft, traction devices on both sides of the unfolding shaft, and a reset device for resetting the unfolding shaft. The first end of the filter screen is fixedly connected to the winding shaft, and both sides of the second end of the filter screen are connected to a traction device. During the unfolding process, the unfolding shaft rotates in the opposite direction by a certain angle under the action of the reset device, returning to its initial state. During this process, the traction devices pull the filter screen to unfold it.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] In related technologies, a traction device is used to directly apply force to both sides of the second end of the filter screen to pull it open. This causes the force to concentrate on both sides of the second end of the filter screen, making the filter screen prone to damage.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0040] Combination Figure 1-6 As shown, this disclosure provides a filter dust removal device 100 for an air conditioner, including a roller assembly 10, a filter 20, a traction rope 30, and a cleaning component 40.

[0041] The roller assembly 10 includes a first roller 11 and a second roller 12; the two ends of the filter screen 20 are respectively wound and connected to the first roller 11 and the second roller 12, and the other end is released when one end of the filter screen 20 is wound up; the two ends of the traction rope 30 are respectively wound and connected to the first roller 11 and the second roller 12, and the other end is released when one end of the traction rope 30 is wound up; the cleaning component 40 is correspondingly arranged with the filter screen 20, and the cleaning component 40 contacts the filter screen 20 during the movement of the filter screen 20 to remove dust; wherein, the first end of the filter screen 20 and the first end of the traction rope 30 are wound and connected to the first roller 11 in opposite directions, and the second end of the filter screen 20 and the second end of the traction rope 30 are wound and connected to the second roller 12 in opposite directions; when the first roller 11 rotates in the forward direction to wind up the filter screen 20, the traction rope 30 is released simultaneously, and when the first roller 11 rotates in the reverse direction to release the filter screen 20, the traction rope 30 is wound up simultaneously.

[0042] The two ends of the traction rope 30 are respectively wound and connected to the first reel 11 and the second reel 12, and the other end is released when one end of the traction rope 30 is wound up. When one end of the traction rope 30 is wound up and the other end is released, it can drive the first reel 11 and the second reel 12 to rotate, thereby driving one of the first reel 11 and the second reel 12 to wind up the filter screen 20 and the other to release the filter screen 20.

[0043] The first end of the filter screen 20 and the first end of the traction rope 30 are wound in opposite directions and connected to the first reel 11. When the first reel 11 rotates in the forward direction to reel in the filter screen 20, the traction rope 30 is released simultaneously. At this time, the second reel 12 releases the filter screen 20 and reels in the traction rope 30. The second end of the filter screen 20 and the second end of the traction rope 30 are wound in opposite directions and connected to the second reel 12. When the first reel 11 rotates in the reverse direction to release the filter screen 20, the traction rope 30 is released simultaneously. At this time, the second reel 12 reels in the filter screen 20 and releases the traction rope 30. "Forward" and "reverse" here refer to two opposite directions of rotation, and are not limited to a specific direction; "forward" can be either clockwise or counterclockwise. For example, during the cleaning process, when the first reel 11 rotates clockwise, it winds up the filter screen 20 and releases the traction rope 30; simultaneously, the second reel 12 rotates clockwise to wind up the traction rope 30 and release the filter screen 20. When the first reel 11 rotates counterclockwise, it winds up the traction rope 30 and releases the filter screen 20; simultaneously, the second reel 12 rotates counterclockwise to wind up the filter screen 20 and release the traction rope 30. This allows the reel assembly 10 to be pulled by the traction rope 30, driving the filter screen 20 to reciprocate, avoiding the problem of force concentration caused by the traction device directly acting on both ends of the filter screen 20 in the prior art.

[0044] The filter dust removal device 100 for air conditioners provided in this embodiment of the present disclosure connects the filter 20 and the traction rope 30 in reverse winding on the first roller 11 and the second roller 12. The traction rope 30 pulls the first roller 11 and the second roller 12 to rewind or unwind, indirectly driving the filter 20 to reciprocate. This effectively reduces the tensile force on both ends of the filter 20, thereby reducing the risk of damage to the filter 20 during cleaning. Simultaneously, the traction rope 30, as a transmission component, has the advantages of low cost and small size, which not only reduces production costs but also improves space utilization, allowing for a more flexible layout of the entire filter dust removal device within the air conditioner. Furthermore, the cleaning component 40 continuously contacts the filter 20 during its movement, efficiently removing dust from the filter 20 and improving the air conditioner's filtration performance and indoor air quality.

[0045] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, the first roller 11 and the second roller 12 are arranged opposite each other along a first direction, and the filter screen 20 reciprocates along the first direction, which is the length or width direction of the filter screen 20.

[0046] The first direction can be either the length or the width of the filter 20. The first roller 11 and the second roller 12 are positioned opposite each other along the first direction, with the filter 20 tensioned between them, forming a single-layer filter 20 structure. Using a single-layer filter 20 reduces wind resistance and improves air intake efficiency. The two ends of the filter 20 are connected to the first roller 11 and the second roller 12, respectively. While one roller is winding up the filter 20, the other is releasing it, allowing the filter 20 to reciprocate along the first direction. This makes the movement path of the filter 20 more regular and stable during unfolding and winding.

[0047] Optionally, combined Figure 5 As shown, the first reel 11 includes a first shaft 111 and a first rope reel 112. The first rope reel 112 is located at the shaft end of the first shaft 111 and is coaxially arranged with the first shaft 111. The first end of the filter screen 20 is wound and connected to the first shaft 111, and the first end of the traction rope 30 is wound and connected to the first rope reel 112. The second reel 12 includes a second shaft 121 and a second rope reel 122. The second rope reel 122 is located at the shaft end of the second shaft 121 and is coaxially arranged with the second shaft 121. The second end of the filter screen 20 is wound and connected to the second shaft 121, and the second end of the traction rope 30 is wound and connected to the second rope reel 122. The first rope reel 112 and the second rope reel 122 are located at the same side shaft end of the first shaft 111 and the second shaft 121.

[0048] The first rope reel 112 is coaxially arranged with the first shaft 111, allowing them to rotate synchronously. The second rope reel 122 is coaxially arranged with the second shaft 121, allowing them to rotate synchronously. The first and second ends of the filter screen 20 can be wound and connected to the first shaft 111 and the second shaft 121, respectively. The first and second ends of the traction rope 30 can be wound and connected to the first rope reel 112 and the second rope reel 122, respectively. This ensures that the winding and unwinding actions of the traction rope 30 are coordinated with those of the filter screen 20. The first rope reel 112 and the second rope reel 122 are located on the same side of the shaft ends of the first shaft 111 and the second shaft 121, making the routing of the traction rope 30 simpler and reducing the risk of the traction ropes 30 becoming tangled.

[0049] Optionally, combined Figure 5 As shown, the second end of the filter screen 20 is pre-wound to the second spool 12. The filter screen 20 includes a filter section unfolded between the first spool 11 and the second spool 12. The length of the pre-wound second end of the filter screen 20 is greater than or equal to the length of the filter section.

[0050] In the cleaning state, the first reel 11 winds up the first end of the filter screen 20 and releases the first end of the traction rope 30, while the second reel 12 releases the second end of the filter screen 20 and winds up the first end of the traction rope 30. When the first reel 11 winds up the filter screen 20, the filter section of the filter screen 20 passes through and comes into contact with the cleaning component 40. The pre-wound length of the second end of the filter screen 20 is greater than or equal to the length of the filter section, so that the entire filter section can come into contact with the cleaning component 40 through movement, improving the thoroughness of cleaning.

[0051] Optionally, combined Figure 1 and Figure 5 As shown, the cleaning component 40 is positioned close to the first roller 11, and a movement gap for the filter screen 20 is formed between the cleaning component 40 and the first roller 11. When the filter screen 20 passes through the movement gap, one side of the filter screen 20 contacts the first roller 11, and the other side of the filter screen 20 contacts the cleaning component 40.

[0052] When the filter screen 20 comes into contact with the cleaning component 40 for cleaning, the first roller 11 provides support to the filter screen 20 on the opposite side of the cleaning component 40, which can improve the cleaning effect.

[0053] Optionally, the traction rope 30 is a soft metal wire harness.

[0054] The soft metal wire harness has high flexibility and strength, which can effectively improve the tensile strength and service life of the traction rope 30 while achieving winding and pulling.

[0055] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, the filter dust removal device for air conditioners also includes a support frame 50 and a positioning part 60. The filter 20 is movably disposed on the surface of the support frame 50. The first roller 11 and the second roller 12 are disposed on the end side of the support frame 50, and the support frame 50 is configured with an installation space 51. The traction rope 30 assembly is disposed in the installation space 51.

[0056] The support frame 50 provides a stable support structure for the filter screen 20 and the reel assembly 10, improving the stability of the filter screen 20 during movement. Placing the traction rope 30 assembly within the installation space 51 constructed by the support frame 50 effectively protects the traction rope 30 from external interference and damage, while also making the overall layout of the device more compact and neat, thus improving space utilization.

[0057] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, the first scroll 11 and the second scroll 12 are located on opposite ends of the support frame 50.

[0058] This effectively enhances the structural stability of the entire device. The layout at both ends ensures that the filter screen 20 is subjected to more even force during winding and unwinding, reducing potential device swaying or filter screen 20 offset caused by the asymmetry of the positions of the first and second rollers 11, and improving the smoothness of device operation.

[0059] Optionally, combined Figure 3 and Figure 6 As shown, the filter dust removal device for air conditioners also includes a positioning part 60, which is located in the installation space 51 of the support frame 50. The positioning part 60 cooperates with the traction rope 30 to limit the movement trajectory of the traction rope 30.

[0060] The positioning part 60 can precisely limit the movement trajectory of the traction rope 30, ensuring that the traction rope 30 maintains the correct path during winding and releasing, thus improving the stability of the traction rope 30's movement trajectory. This also avoids problems such as rope tangling, deviation, or slackness, optimizes the force distribution of the traction rope 30, reduces local wear on the traction rope 30, and extends the service life of the traction rope 30.

[0061] Optionally, combined Figure 3 and Figure 6 As shown, the positioning part 60 is detachably connected to the support frame 50.

[0062] The detachable connection design between the positioning part 60 and the support frame 50 allows for quick disassembly and installation of the positioning part 60. This facilitates easy replacement or maintenance of the positioning part 60 and the traction rope 30 without disassembling the entire support frame 50 or other components, significantly saving maintenance time and costs. The positioning part 60 can snap into the support frame 50. A snap-fit ​​structure 52 is provided within the installation space 51 of the support frame 50, and the positioning part 60 is embedded in the snap-fit ​​structure 52 to secure it to the support frame 50. This snap-fit ​​design allows the positioning part 60 to be quickly installed onto the support frame 50 without the need for screws, nuts, or other fasteners, improving maintenance efficiency.

[0063] Optionally, combined Figure 3 As shown, the positioning part 60 is provided with a guide channel 601, which extends along the movement direction of the filter screen 20, and the traction rope 30 passes through the guide channel 601; when there are multiple positioning parts 60, the multiple positioning parts 60 are arranged along the movement direction of the filter screen 20, and the traction rope 30 is sequentially passed through the guide channel 601 of the multiple positioning parts 60.

[0064] The guide channel 601 of the positioning part 60 extends along the movement direction of the filter screen 20, which can more effectively constrain the movement of the traction rope 30 and prevent the traction rope 30 from swinging left and right or deviating from the predetermined path during movement. Multiple positioning parts 60 can be arranged at intervals or sequentially along the movement direction of the filter screen 20. When there are multiple positioning parts 60 arranged along the movement direction of the filter screen 20, the traction rope 30 is sequentially passed through multiple guide channels 601, which can further enhance the control accuracy of the traction rope 30's movement trajectory. This allows the traction rope 30 to maintain stable and accurate force at different positions along the movement path, improving the stability and uniformity of the tension in the traction rope 30, thereby improving the smoothness of the filter screen 20's movement. At the same time, the arrangement of multiple positioning parts 60 can also distribute the tension on the traction rope 30, reducing the burden on a single positioning part 60. The positioning part 60 can be a positioning block, with the guide channel 601 passing through it.

[0065] Optionally, combined Figure 1 , Figure 2 and Figure 4-6 As shown, the filter dust removal device for air conditioners also includes a drive unit 70 and a gear set 80; the gear set 80 is drivenly connected to the drive unit 70, and the gear set 80 is transmittedly connected to the first roller 11 and the second roller 12. The drive unit 70 drives the gear set 80 to rotate to drive the first roller 11 and the second roller 12 to move, thereby driving the filter 20 to move.

[0066] The drive unit 70, acting as a power source, can stably output power. The drive unit 70 can be a motor, such as a stepper motor or a servo motor. Through the transmission of the gear set 80, power is accurately transmitted to the first and second reels 11 and 12, improving the rotational stability of the first and second reels 11 and 12. The gear set 80 has an accurate transmission ratio and high transmission efficiency, enabling precise control of the speed and direction of the first and second reels 11 and 12, thus achieving precise control of the speed and direction of the filter screen 20. During the cleaning process of the filter screen 20, precise motion control allows the filter screen 20 to pass through the cleaning component 40 at an appropriate speed, thereby improving the cleaning effect. Furthermore, the gear set 80 also provides a certain degree of speed reduction and torque amplification, meeting the torque requirements of the reel assembly 10 when winding the filter screen 20, ensuring smooth winding of the filter screen 20.

[0067] Optionally, combined Figure 1 and Figure 5 As shown, the gear set 80 is also connected to the cleaning component 40 in a transmission connection to drive the cleaning component 40 to move when the filter screen 20 is driven to move.

[0068] The movement of the cleaning component 40 and the filter screen 20 is linked by the gear set 80, so that the movement of the cleaning component 40 is synchronized with the winding and unwinding process of the filter screen 20. When the filter screen 20 moves, the cleaning component 40 can clean the filter screen 20 in real time. This avoids the time difference between the movement of the cleaning component 40 and the filter screen 20, and improves cleaning efficiency.

[0069] Optionally, combined Figure 1 and Figure 5 As shown, the gear set 80 includes a drive gear 81 and a first gear 82. The drive gear 81 is drivenly connected to the drive member 70. The first gear 82 is drivenly connected to both the drive gear 81 and the first spool 11 to drive the first spool 11 to rotate.

[0070] The drive gear 81 can directly mesh with the first gear 82, which can improve the efficiency and accuracy of power transmission. The drive gear 81 can also be indirectly connected to the first gear 82, and power transmission can be achieved by introducing intermediate transmission components such as intermediate gears. The transmission path and transmission ratio can be adjusted according to different needs.

[0071] The connection between the drive gear 81 and the drive component 70 efficiently transmits the power of the drive component 70 to the entire gear set 80. The first gear 82 is connected to the drive gear 81 and the first reel 11, enabling precise transmission control of the first reel 11. By rationally designing the gear ratio, the speed and torque of the first reel 11 can be adjusted to meet the different needs of winding and unwinding the filter screen 20. During the winding process of the filter screen 20, as the winding diameter of the filter screen 20 increases, a greater torque is required. The first gear 82 can provide sufficient torque to the first reel 11 by adjusting the transmission ratio, ensuring the smooth progress of the winding process. The transmission between the drive gear 81 and the first gear 82 not only improves the efficiency of power transmission but also reduces noise and vibration.

[0072] Optionally, combined Figure 1 and Figure 5 As shown, the first gear 82 is coaxially arranged with the first reel 11.

[0073] This allows the first gear 82 and the first roller 11 to rotate synchronously. When the drive gear 81 drives the first gear 82 to rotate, the first roller 11 can wind up or unwind the filter screen 20 at the same speed and torque, thereby improving the stability of the filter screen 20's movement.

[0074] Optionally, combined Figure 1 and Figure 5 As shown, the first spool 11 includes a first shaft body 111 and a first rope reel 112. A first gear 82 is disposed at one end of the first rope reel 112 away from the first shaft body 11, and the first gear 82 is coaxially arranged with the first rope reel 112.

[0075] In this way, the driving component drives the active transmission gear 81 to drive the first gear 82 to rotate, which in turn drives the first rope reel 11 to rotate synchronously, thereby driving the first rope reel to wind up or release the traction rope. The first shaft 111 is coaxially arranged with the first rope reel 112 and the first gear 82. While the first gear 82 drives the first rope reel 11 to rotate synchronously, it can also drive the first shaft 111 to rotate synchronously, thereby driving the first shaft 111 to wind up or release the filter screen.

[0076] Optionally, combined Figure 4 and Figure 5 As shown, the gear set 80 also includes a second gear 83, which is connected to both the drive gear 81 and the cleaning component 40 to drive the cleaning component 40 to rotate.

[0077] The drive gear 81 can directly mesh with the second gear 83, which can improve the efficiency and accuracy of power transmission. The drive gear 81 can also be indirectly connected to the second gear 83, and power transmission can be achieved by introducing intermediate transmission components such as intermediate gears. The transmission path and transmission ratio can be adjusted according to different needs.

[0078] The driving component 70 is driven by the active transmission gear 81, which in turn is driven by the second gear 83, and further driven by both the active transmission gear 81 and the cleaning component 40. This achieves synchronous driving of the cleaning component 40, enabling it to work in sync with the movement of the filter screen 20. Through the transmission of the second gear 83, the speed and direction of the cleaning component 40 can be precisely controlled, ensuring that it contacts the filter screen 20 with appropriate force and frequency as it passes, thus improving the cleaning effect. The cleaning component 40 can be a brush, a sponge, felt, or other cleaning structure.

[0079] When the air conditioner is operating normally, the second end of the filter is wound onto the second shaft, and the first end of the traction rope is wound onto the first reel. The filter section of the filter is tensioned between the first and second shafts to filter the incoming airflow. During filter self-cleaning, the drive unit drives the first gear to rotate the first reel to release the traction rope and causes the first shaft to wind up the filter. The cleaning component contacts the filter on the side of the first shaft to clean it. Simultaneously, the second shaft releases the filter, and the second reel rotates to wind up the traction rope. After self-cleaning, the drive unit drives the first gear to rotate in the opposite direction to release the filter from the first shaft and cause the first reel to wind up the traction rope. As the first reel winds up the traction rope, the movement of the traction rope causes the second reel to release the traction rope, thereby causing the second shaft to rotate and wind up the filter. This avoids the filter end being directly pulled by the traction rope or other structures during movement, thus reducing the risk of filter damage.

[0080] This application takes an example where the active drive gear 81 meshes with the first gear 82 and the second gear 83. The motor drives the active drive gear 81 to rotate, which in turn drives the first gear 82 and the second gear 83 to rotate in the same direction, thereby causing the first roller 11 and the cleaning component 40 to rotate in the same direction. During the cleaning process, the first roller 11 rotates to wind up the filter screen 20, while the drive component 70, through the gear set 80, drives the cleaning component 40 to rotate towards the filter screen 20, achieving efficient cleaning of the filter screen 20.

[0081] Optionally, combined Figure 1 and Figure 5 As shown, the second gear 83 is coaxially arranged with the cleaning component 40.

[0082] This allows the second gear 83 and the cleaning component 40 to rotate synchronously. When the drive gear 81 drives the second gear 83 to rotate, the cleaning component 40 can rotate at the same speed and torque to clean the filter screen 20, thereby improving the stability of the movement of the cleaning component 40.

[0083] Optionally, the transmission ratio between the drive gear 81 and the second gear 83 is greater than the transmission ratio between the drive gear 81 and the first gear 82, so that the rotational speed of the second gear 83 is greater than the rotational speed of the first gear 82.

[0084] The transmission ratio between the driving gear 81 and the second gear 83 refers to the total transmission ratio between the driving gear 81 and the second gear 83. The transmission ratio between the driving gear 81 and the first gear 82 refers to the total transmission ratio between the driving gear 81 and the first gear 82.

[0085] The transmission ratio between the drive gear 81 and the second gear 83 is greater than the total transmission ratio between the drive gear 81 and the first gear 82, resulting in a higher rotational speed of the second gear 83 than that of the first gear 82. This causes the cleaning component 40 to rotate at a higher speed than the first roller 11, thus allowing the cleaning component 40 to rotate at a higher speed than the filter screen 20. During the self-cleaning process of the filter screen 20, the high-speed rotation of the cleaning component 40 generates a stronger cleaning force, effectively cleaning the dust on the filter screen 20.

[0086] Optionally, combined Figure 1 and Figure 5 As shown, the axial dimension of the cleaning component 40 is adapted to the axial dimension of the first reel 11.

[0087] This allows the cleaning component 40 to fully cover the axial range of the first roll 11. As the filter screen 20 passes through the cleaning component 40, the cleaning component 40 can clean the filter screen 20 evenly and thoroughly, avoiding cleaning blind spots caused by size mismatch, thereby improving the cleaning effect.

[0088] Optionally, combined Figure 1 and Figure 5 As shown, the first spool 11 and the second spool 12 have the same axial dimensions.

[0089] The first roll 11 and the second roll 12 have the same axial dimensions, making the entire filter dust removal device more symmetrical and balanced in structure. The symmetrical axial dimensions ensure that the filter 20 is subjected to more uniform force during winding and unwinding, which can improve the stability of the filter 20's movement.

[0090] Combination Figure 7As shown, this embodiment of the present disclosure provides an air conditioner, including a housing 90 and a filter dust removal device 100 for an air conditioner as described in any of the above-disclosed embodiments. The housing 90 is provided with an air inlet 91; the filter 20 is provided at the air inlet 91.

[0091] The filter 20 is located at the air inlet 91. When the air conditioner is running, the filter 20 can intercept tiny particles such as dust, hair, and dander in the air, preventing these impurities from entering the air conditioner. At the same time, through the automatic cleaning function, the cleaning component can promptly remove the impurities accumulated on the filter 20, keeping the filter 20 clean.

[0092] Optionally, multiple filter dust removal devices 100 are arranged side by side along the length of the air inlet 91. This can effectively improve the cleaning effect.
