Description

Technical Field

[0001] This application relates to the field of air conditioner technology, specifically to a filter self-cleaning device for air conditioners 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 self-cleaning of dust on the filter screen, the related technology provides an indoor air conditioner. The air conditioner includes a filter screen assembly, an indoor heat exchanger, and a cleaning device. The filter screen assembly includes a filter screen and a drive shaft for driving the filter screen to move. A synchronous belt assembly is arranged in the direction of movement of the filter screen. The synchronous belt assembly includes two synchronous belts, which are respectively arranged on both sides of the filter screen. The synchronous belt assembly is sleeved on a first synchronous pulley assembly and a second synchronous pulley assembly. The rotation of the drive shaft drives the first synchronous pulley assembly to rotate and drives the synchronous belt assembly to perform transmission, thereby driving the filter screen to perform cyclic movement in a circular path.

[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, the two synchronous belts of the synchronous belt assembly are respectively set on both sides of the filter screen, resulting in the filter screen assembly occupying a large space and increasing the difficulty of layout of the internal space of the indoor air conditioner.

[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.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0044] Combination Figure 1-9 As shown, this embodiment of the present disclosure provides a filter self-cleaning device 100 for an air conditioner, including a support frame 50, a filter 20, a traction rope 30, and a driving member 70. The support frame 50 has an inwardly recessed end along its width direction to form an installation space 51, which extends along its length direction. The filter 20 is disposed on the support frame 50 and is movable relative to the support frame 50 along its length direction. The traction rope 30 is disposed within the installation space 51, and its two ends are respectively connected to the two ends of the filter 20. The driving member 70 is drivenly connected to the traction rope 30, and drives the traction rope 30 to move along the length direction of the support frame to move the filter 20.

[0045] The width direction of the supporting frame 50 is as follows Figure 1 As indicated by the middle arrow, the length direction of the supporting frame 50 is as follows: Figure 5 The direction indicated by the middle arrow.

[0046] The filter self-cleaning device 100 for air conditioners provided in this embodiment of the present disclosure provides a stable support structure for the filter 20 via the support frame 50, which improves the stability of the filter 20 during movement. The traction rope 30 is placed within the inwardly recessed installation space 51 at the end of the support frame 50, making the overall structure of the filter self-cleaning device 100 more compact, saving space and effectively improving space utilization. Simultaneously, the installation space 51 also protects the traction rope 30, preventing damage from external interference. Furthermore, the traction rope 30, as a transmission component, has the advantages of low cost and small size, which not only improves space utilization and allows for more flexible layout of the entire filter self-cleaning device 100 within the air conditioner, but also reduces production costs.

[0047] Optionally, combined Figure 4 As shown, a first rope section 112 and a second rope section 122 are used for the self-cleaning device of the air conditioner filter. The second rope section 122 and the first rope section 112 are arranged opposite to each other along the length of the support frame. The first rope section 112 and the second rope section 122 are both located in the installation space 51. The two ends of the traction rope 30 are respectively wound and connected to the first rope section 112 and the second rope section 122.

[0048] The two ends of the traction rope 30 are respectively wound and connected to the first rope coil 112 and the second rope coil 122, so that the traction rope 30 can accurately transmit power to the first shaft 111 and the second shaft 121 through the first rope coil 112 and the second rope coil 122. The first rope coil and the second rope coil are both located in the installation space 51, which further improves the compactness of the overall layout of the device.

[0049] Optionally, combined Figure 2 and Figure 3 As shown, the first rope section 112 is provided with a first rope groove 113, the size of which is adapted to the radial dimension of the traction rope; and / or, the second rope section 122 is provided with a second rope groove 123, the size of which is adapted to the radial dimension of the traction rope.

[0050] This reduces the space occupied by the first and second rope sections in the width direction of the support frame, and also allows the traction rope to be layered and wound in the first and / or second rope grooves, preventing the traction rope from getting tangled and improving transmission stability.

[0051] Optionally, combined Figure 5As shown, the filter self-cleaning device 100 for an air conditioner also includes a positioning part 60, which is provided in the installation space 51. The positioning part 60 has a guide channel 601 extending along the length direction of the support frame, 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 length direction of the support frame, and the traction rope 30 is sequentially passed through the guide channel 601 of the multiple positioning parts 60.

[0052] 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.

[0053] The guide channel 601 of the positioning part 60 extends along the length of the support frame, that is, along the direction of movement of the traction rope 30. This more effectively constrains the movement of the traction rope 30, preventing it from swaying left and right or deviating from the predetermined path during movement. Multiple positioning parts 60 can be arranged at intervals or sequentially along the length of the support frame (the direction of movement of the filter screen 20). When there are multiple positioning parts 60 arranged along the length of the support frame, the traction rope 30 passes sequentially through multiple guide channels 601, further enhancing the control precision of the traction rope 30's movement trajectory. This ensures that the traction rope 30 maintains 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. Simultaneously, the arrangement of multiple positioning parts 60 also disperses 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.

[0054] Optionally, combined Figure 5 As shown, the support frame 50 has a snap-fit ​​part 52 in the installation space 51, and the positioning part 60 cooperates with the snap-fit ​​part 52 so that the positioning part 60 and the support frame 50 can be detachably connected.

[0055] The positioning part 60 and the support frame 50 are connected by a snap-fit ​​detachable design, allowing the positioning part 60 to be quickly disassembled and installed. This makes it easy to replace or maintain the positioning part 60 and the traction rope 30 without disassembling the entire support frame 50 or other components, greatly saving maintenance time and costs.

[0056] Optionally, combined Figure 4 As shown, the snap-fit ​​part 52 is a snap-fit ​​groove 521, and the positioning part 60 is embedded in the snap-fit ​​groove 521, which can be fixed to the support frame 50.

[0057] In this way, the positioning part 60 can be quickly installed onto the support frame 50 without the need for screws, nuts or other fasteners, which can improve maintenance efficiency.

[0058] Optionally, combined Figure 7 As shown, the support frame 50 also includes a support part 53, which is located in the installation space 51 and is supported on the underside of the traction rope 30.

[0059] The support portion 53 is supported on the lower side of the first traction rope 31 and / or the second traction rope 32, which can prevent the traction rope 30 from sagging or swinging during movement, thereby improving the movement stability of the first traction rope 31 and / or the second traction rope 32. The support portion 53 can be a support column structure, and the circumferential surface of the support column is in support contact with the traction rope 30.

[0060] Optionally, the positioning part 60 is provided with an oil injection hole that connects to the guide channel 601 for injecting lubricating oil into the guide channel 601 to lubricate the traction rope 30.

[0061] The oil injection hole provided on the positioning part 60 allows lubricating oil to be injected into the guide channel 601, thereby effectively lubricating the traction rope 30, reducing the friction between the traction rope 30 and the guide channel 601, reducing the wear rate of the traction rope 30, extending the service life of the traction rope 30, and also reducing the noise generated by friction.

[0062] Optionally, combined Figure 6 As shown, the support frame 50 has a first shaft mounting cavity 55 at its first end along the length direction of the support frame, and a second shaft mounting cavity 56 at its second end along the length direction of the support frame. Both the first shaft mounting cavity 55 and the second shaft mounting cavity 56 are connected to the mounting space 51. The filter self-cleaning device also includes a first shaft 111 and a second shaft 121. The first shaft is located in the first shaft mounting cavity, and a first rope winding portion is located at the shaft end of the first shaft, and the first rope winding portion is coaxially connected to the first shaft. The second shaft is located in the second shaft mounting cavity, and a second rope winding portion is located at the shaft end of the second shaft, and the second rope winding portion is coaxially connected to the second shaft. The filter screen can be wound around the first shaft and the second shaft at both ends along the length direction of the support frame.

[0063] By providing a first shaft mounting cavity 55 and a second shaft mounting cavity 56 at both ends of the support frame 50 along its length, and connecting them to the mounting space 51, dedicated mounting positions are provided for the first shaft 111 and the second shaft 121. This also allows the first and second rope winding portions located within the mounting space 51 to be stably and precisely connected to the shaft ends of the first shaft 111 and the second shaft 121, respectively. The first shaft mounting cavity 55 and the second shaft mounting cavity 56 effectively limit the radial and axial displacement of the first shaft 111 and the second shaft 121, reducing vibration and swaying, and enabling the first shaft 111 and the second shaft 121 to rotate smoothly. This not only facilitates the installation and fixation of the first shaft 111 and the second shaft 121, but also improves the stability of the first shaft 111 and the second shaft 121 during movement. The first rope section 112 is coaxial with the first shaft 111, and the second rope section 122 is coaxially connected with the second shaft 121, so that the winding and releasing action of the traction rope 30 can be directly converted into the rotational motion of the first shaft 111 and the second shaft 121, thereby driving the filter screen 20 to move stably. The first rope section 112 and the first shaft 111 are coaxially connected to form the first shaft 11. The second rope section 122 and the second shaft 121 are coaxially connected to form the second shaft 12.

[0064] Optionally, combined Figure 7 As shown, the support frame 50 also includes a separator 54, which is disposed in the installation space 51. The separator 54 extends along the length of the support frame to divide the installation space 51 into a first space 511 and a second space 512. There are multiple traction ropes 30, including a first traction rope 31 and a second traction rope 32. The first traction rope 31 is disposed in the first space 511, and the second traction rope 32 is disposed in the second space 512. The two ends of the first traction rope 31 and the second traction rope 32 form a reverse winding structure in the first coil and the second coil, respectively. When one end of the first traction rope 31 is wound up, the other end is released. When one end of the second traction rope 32 is wound up, the other end is released.

[0065] The separator 54 can divide the installation space 51 into a first space 511 and a second space 512 arranged vertically, or it can divide the installation space 51 into a first space 511 and a second space 512 arranged horizontally. By setting the separator 54 to divide the installation space 51 into the first space 511 and the second space 512, the first traction rope 31 and the second traction rope 32 can run in independent spaces, effectively preventing them from getting tangled or interfering during movement, ensuring the smooth movement of the traction rope 30 and the stable winding and release of the filter screen 20. The separator 54 can be a partition plate extending along the length of the support frame.

[0066] The first rope section has two first rope grooves that engage with the first and second traction ropes during winding. The second rope section has two second rope grooves that engage with the first and second traction ropes during winding. The two ends of the first traction rope 31 and the second traction rope 32 form a reverse winding structure on the first rope section and the second rope section, respectively. Throughout the transmission process, the two ends of the first traction rope 31 are always in a state where one end is wound up and the other end is unwound, and the two ends of the second traction rope 32 are also always in a state where one end is wound up and the other end is unwound.

[0067] When the first coil rotates in one direction to wind up the first traction rope 31, the second coil correspondingly releases the first traction rope 31; simultaneously, the second coil rotates in the same direction to wind up the second traction rope 32, and the first coil correspondingly releases the second traction rope 32, thereby enabling the filter screen 20 to move in one direction. For example, when the first coil rotates clockwise to wind up the first traction rope 31, the second coil releases the first traction rope 31, and simultaneously, when the second coil rotates clockwise to wind up the second traction rope 32, the first coil releases the second traction rope 32.

[0068] When the first coil rotates in the opposite direction to wind up the second traction rope 32, the second coil will correspondingly release the second traction rope 32; simultaneously, when the second coil rotates in the opposite direction to wind up the first traction rope 31, the first coil will correspondingly release the first traction rope 31, thereby enabling the filter screen 20 to move in the opposite direction. For example, when the first coil rotates counterclockwise to wind up the second traction rope 32, the second coil releases the second traction rope 32, and simultaneously, when the second coil rotates counterclockwise to wind up the first traction rope 31, the first coil releases the first traction rope 31.

[0069] In this embodiment, the traction transmission of the first traction rope 31 and the second traction rope 32 enables the first and second rope coils to rotate synchronously, thereby achieving the reciprocating motion of the filter screen 20. The indirect transmission via the first traction rope 31 and the second traction rope 32 avoids directly applying tension to the filter screen 20, thus reducing the risk of damage due to excessive stretching or uneven local stress and extending the service life of the filter screen 20. Furthermore, the first traction rope 31 and the second traction rope 32 are compact and small in size, both housed within the installation space 51, effectively reducing space occupation and improving the space utilization rate of the air conditioner.

[0070] Optionally, combined Figure 3-5 As shown, the filter self-cleaning device 100 for air conditioners also includes a gear set 80, which is disposed in the installation space 51. The gear set 80 is connected to the first end of the traction rope 30 and is also connected to the drive member 70.

[0071] The gear set 80 can efficiently transmit the driving force of the drive unit 70 to the traction rope 30, thereby achieving precise adjustment of the movement speed and torque of the traction rope 30, and thus more accurately controlling the winding and unwinding speed of the filter screen 20, improving the uniformity and effectiveness of the cleaning of the filter screen 20.

[0072] Optionally, with the first spool 11 located at the first end of the support frame 50 along the length of the support frame, the second spool 12 located at the second end of the support frame 50 along the length of the support frame, and the first end of the traction rope 30 being wound around the shaft end of the first spool 11 and the second end of the traction rope 30 being wound around the second spool 12, the gear set 80 is drivenly connected to the shaft end of the first spool 11.

[0073] The gear set 80 is driven to the shaft end of the first reel 11. The gear set 80 drives the first reel 11 to rotate, causing the first end of the traction rope 30 to wind up to the shaft end of the first reel 11. Simultaneously, the second end of the traction rope 30 is released from the shaft end of the second reel 12, which rotates to release the filter screen 20. The gear set 80 is located in the mounting space 51, avoiding the need for additional space, while still enabling transmission with the traction rope 30 located in the mounting space 51. With the first reel 11 including a first shaft body 111 and a first rope winding portion, the gear set 80 within the mounting space 51 can be driven to connect with the first rope winding portion located in the mounting space 51 and the first shaft body 111 located in the mounting cavity of the first reel 11. This allows the gear set 80 to drive the first end of the traction rope 30 to wind up via the first rope winding portion, while efficiently transmitting the power of the drive unit 70 to the first shaft body 111, thereby driving the first end of the filter screen 20 to wind up.

[0074] Optionally, combined Figure 3 and Figure 4 As shown, the filter self-cleaning device 100 for an air conditioner also includes a cleaning component 40, which is disposed at the first end of the support frame 50 along the length of the support frame. The cleaning component 40 contacts the filter 20 during the movement of the filter 20 to clean the filter 20. The gear set 80 includes a drive gear 81, a first gear 82 and a second gear 83. The drive gear 81 is drivenly connected to the drive component 70. The first gear 82 is drivenly connected to the drive gear 81 and is coaxially connected to the first roller 11. The second gear 83 is drivenly connected to the drive gear 81 and is coaxially connected to the cleaning component 40.

[0075] The drive unit 70 drives the first gear 82 to rotate via the drive gear 81, which in turn drives the first reel 11 to rotate. In some embodiments, the first gear 82 can drive the first rope section 112 to rotate synchronously, thereby enabling the first rope section 112 to wind up or release the traction rope 30. The first shaft 111 is coaxially arranged with the first rope section 112 and the first gear 82. While the first gear 82 drives the first rope section 112 to rotate synchronously, it can also drive the first shaft 111 to rotate synchronously, thereby enabling the first shaft 111 to wind up or release the filter screen 20. The drive gear 81 can directly mesh with the first gear 82.

[0076] The second gear 83 is connected to the drive gear 81 and coaxially connected to the cleaning component 40, enabling the cleaning component 40 to move. This allows the gear set 80 to simultaneously rotate the first roller 11 and the cleaning component 40, causing the cleaning component 40 to rotate towards the filter screen 20 during its movement, thus improving the cleaning effect. The drive gear 81 can directly mesh with the second gear 83, improving the efficiency and precision of power transmission. Alternatively, the drive gear 81 can be indirectly connected to the second gear 83 by introducing intermediate transmission components such as intermediate gears to achieve power transmission, allowing adjustment of the transmission path and ratio according to different needs.

[0077] The gear set 80 is not only connected to the traction rope 30 for transmission, but also coaxially connected to the cleaning component 40, enabling the cleaning component 40 to move while driving the filter screen 20. The movement of the cleaning component 40 can clean the filter screen 20 in real time, improving cleaning efficiency. The drive gear 81, the first gear 82, and the second gear 83 included in the gear set 80 are all located within the installation space 51. This integrated design makes the entire transmission system more compact, reduces the space occupied by the transmission components in the exposed parts, and improves the overall structural compactness of the device. Placing the gear set 80 within the installation space 51 also prevents external foreign objects from entering the gear set 80, reducing wear and interference from dust, debris, etc., thereby improving the operational stability and service life of the gear set 80.

[0078] The cleaning component 40 can be a brush, or a cleaning structure such as a sponge or felt.
