The traditional air duct machine can be provided with two air outlet modes by additionally arranging a rotary air duct component, wherein one air outlet mode is lower air inlet and side air outlet; the other is that the side air inlet is used for air inlet, and the lower air outlet is used for air outlet. Correspondingly, in order to meet the switching state of the tuyere, the filter screen is converted into a movable filter screen from a fixed filter screen. In order to achieve the movability of the screen, a drive transmission must be provided. For traditional filter screen, the installation and the dismantlement of filter screen are realized to the joint connection of accessible wind-guiding frame and wind gap. The movable filter screen is difficult to detach due to the linkage relation between the filter screen and the driving or transmission component.

The embodiment of the disclosure provides a filter screen mechanism and an air conditioner, wherein a scroll 2 and an air guide frame 1 are detachably connected, and a slide rod 3 and a first transmission mechanism 5 are detachably connected, so that the problem that a filter screen 4 is difficult to detach is solved.

As shown in fig. 1 to 12, an air conditioner according to an embodiment of the present disclosure includes a housing and the above-described filter mechanism. The casing is provided with a first air opening 12 and a second air opening 13, the first air opening 12 comprises a first air guiding frame 1, and the second air opening 13 comprises a second air guiding frame 1. The first air guide frame 1 and the second air guide frame 1 are both provided with the filter screen mechanism.

Specifically, when the first air port 12 is an air return port and the second air port 13 is an air outlet port, the filter screen 4 on the filter screen mechanism on the side of the second air port 13 can be controlled to be wound on the reel 2, the filter screen 4 on the filter screen mechanism on the side of the first air port 12 is controlled to be stretched along with the sliding rod 3 in a sliding manner, the air port is shielded, the filter screen 4 of the second air port 13 is prevented from being led to avoid the second air port 13, and the filter screen 4 of the first air port 12 filters the first air port 12; similarly, when the first air port 12 is an air outlet and the second air port 13 is an air return port, the filter screen 4 at the side of the second air port 13 can be unfolded to filter the second air port 13, and the filter screen 4 at the side of the first air port 12 is wound on the reel 2 to avoid the first air port 12, so that the air flow purifying requirement of the air conditioner capable of reversely blowing air is met.

In some embodiments, the first air guiding frame 1 is provided with two sets of filter mechanisms in parallel along the length direction of the first air port 12, and/or the second air guiding frame 1 is provided with two sets of filter mechanisms in parallel along the length direction of the second air port 13.

By the arrangement, when the whole length of the air conditioner is too long, the problems of loosening and clamping caused by too long filter screen 4 can be avoided. It can be understood that the filter screen 4 located at the air port at the side of the air conditioner can move up and down or left and right, and the filter screen 4 located at the air port at the lower part of the air conditioner can move back and forth or left and right, and can be specifically configured and installed according to the requirement.

As shown in fig. 1 to 7, the embodiment of the present disclosure provides a filter screen mechanism, which is installed on an air guiding frame 1 at an air inlet side of an indoor unit of an air conditioner, wherein the air guiding frame 1 includes a first side portion and a second side portion which are oppositely arranged, and the filter screen mechanism includes a first transmission mechanism 5, a sliding rod 3 and a lock catch 301. The first transmission mechanism 5 is fixedly arranged on the air guiding frame 1, and the first transmission mechanism 5 is provided with a connecting piece 501. The slide bar 3 includes a clamping groove 302 provided at an end thereof, and the slide bar 3 is reciprocatingly movable between a first side portion and a second side portion of the air guiding frame 1. The lock catch 301 is slidably disposed in the clamping groove 302. The lock 301 may be engaged with the connecting piece 501 to fix the sliding rod 3 to the first transmission mechanism 5, and when the lock 301 is disengaged from the connecting piece 501, the sliding rod 3 may be detached from the first transmission mechanism 5.

Specifically, when the lock catch 301 slides from the first end to the second end of the locking slot 302, the lock catch 301 may be locked to the connecting piece 501 to fix the sliding rod 3 to the first transmission mechanism 5. When the lock catch 301 slides from the second end to the first end of the clamping groove 302, the lock catch 301 can be separated from the connecting piece 501 so that the sliding rod 3 can be removed from the first transmission mechanism 5. When the sliding rod 3 is fixed on the first transmission mechanism 5, the first transmission mechanism 5 can drive the sliding rod 3 to move from the first side part to the second side part of the air guiding frame 1. Similarly, the first transmission mechanism 5 may also drive the sliding rod 3 to move from the second side portion to the first side portion of the air guiding frame 1.

As shown in fig. 4, in some embodiments, a through hole 3022 is provided on a first side of the clamping groove 302, and a locking hole 5012 is provided at a position of the connection member 501 corresponding to the through hole 3022. The lock catch 301 may be fastened to the locking hole 5012 through the through hole 3022 to fix the slide rod 3 to the first transmission mechanism 5.

Specifically, the first end of the lock catch 301 is provided with a locking protrusion 3013, and when the lock catch 301 slides from the first end to the second end of the locking groove 302, the locking protrusion 3013 may pass through the through hole 3022 of the locking groove 302 and be locked to the locking hole 5012 of the connecting piece 501, so as to fix the slide rod 3 to the first transmission mechanism 5. When the lock catch 301 slides from the second end to the first end of the locking groove 302, the locking protrusion 3013 is disengaged from the locking hole 5012 of the connector 501 and the through hole 3022 of the locking groove 302, so that the slide bar 3 is detachable from the first transmission mechanism 5.

As shown in fig. 4 and 6, in some embodiments, a guide groove 3023 is further provided on the bottom surface of the clamping groove 302, and a guide block 3011 is provided at a position of the lock catch 301 corresponding to the guide groove 3023. The guide block 3011 is inserted into the guide slot 3023, and is used for slidably guiding the lock catch 301.

Specifically, the clip groove 302 is provided with two guide grooves 3023 along the sliding direction of the latch 301, and the latch 301 is provided with two guide blocks 3011 corresponding to each guide groove 3023. When the lock catch 301 slides in the clamping groove 302, the guide groove 3023 can cooperate with the guide block 3011 to guide the lock catch 301.

As shown in fig. 5, in some embodiments, the connecting member 501 is further provided with a relief groove 5011, and the end of the slide bar 3 is provided with a bump 3021 that can overlap the relief groove 5011.

Specifically, the first side of the connecting piece 501 is provided with a relief groove 5011, and the end of the slide bar 3 is provided with a bump 3021. When the bump 3021 of the sliding rod 3 is overlapped with the avoiding slot 5011, the lock catch 301 can slide from the first end to the second end of the clamping slot 302, so as to fix the sliding rod 3 to the first transmission mechanism 5, so that the first transmission mechanism 5 drives the sliding rod 3 to move. When the lock catch 301 slides from the second end to the first end of the clamping groove 302, the protruding block 3021 of the sliding rod 3 can be taken out from the avoiding groove 5011 to detach the sliding rod 3 from the first transmission mechanism 5.

As shown in fig. 6, in some embodiments, the clamping groove 302 is further provided with a limiting structure, and the lock catch 301 is further provided with a first limiting protrusion 3014, and when the lock catch 301 is clamped in the locking hole 5012, the first limiting protrusion 3014 can be clamped in the limiting structure and limit the lock catch 301.

Specifically, when the lock catch 301 is forced to slide from the first end to the second end of the locking slot 302 and is locked to the connecting piece 501, the first limiting protrusion 3014 can be limited by the limiting structure of the locking slot 302, so as to prevent the lock catch 301 from being separated from the connecting piece 501. When the lock catch 301 is forced to slide from the second end to the first end of the clamping groove 302, the limiting structure releases the limitation of the first limiting protrusion 3014, so that the lock catch 301 can be separated from the connecting piece 501.

As shown in fig. 6, in some embodiments, the latch 301 is further provided with a second limiting protrusion 3015, and the second limiting protrusion 3015 abuts against an inner wall surface of the latch groove 302.

Specifically, when the lock catch 301 slides in the clamping groove 302, the second limiting protrusion 3015 abuts against the inner wall surface of the clamping groove 302, so as to limit the sliding direction of the lock catch 301.

It is understood that when the latch 301 slides in the latch slot 302, the second limiting protrusion 3015 cannot be limited by the limiting structure of the latch slot 302.

As shown in fig. 6, in some embodiments, the latch 301 further includes a support rib 3012 abutting against the clamping slot 302, for supporting the latch 301 to slide.

Specifically, the supporting rib 3012 is disposed on the bottom surface of the lock catch 301 and is disposed in contact with the inner wall surface of the locking slot 302, so as to support the lock catch 301 to slide in the locking slot 302.

It can be appreciated that the supporting rib 3012 is disposed on the bottom surface of the lock catch 301, so as to support the sliding of the lock catch 301, so that the contact area between the lock catch 301 and the lock catch 302 when sliding in the lock catch 302 can be reduced, and further the sliding friction force is reduced, which is beneficial for the lock catch 301 to slide in the lock catch 302.

In some embodiments, the latch 301 is also provided with a push-button 3016.

Specifically, the latch 301 may be pushed by the pushing hand 3016 to slide in the latch slot 302.

As shown in fig. 1, in some embodiments, the screen mechanism described above further includes a spool 2 and a screen 4. The scroll 2 is rotatably disposed at a first side portion of the air guiding frame 1, and is detachably connected with the air guiding frame 1. The first end of the filter screen 4 is fixedly connected with the slide bar 3, and the second end is fixedly connected with the scroll 2. The sliding rod 3 can move from the first side to the second side to enable the filter screen 4 to be flattened on the air guiding frame 1, and the sliding rod 3 can also move from the second side to the first side to enable the filter screen 4 to be wound on the scroll 2.

Specifically, the sliding rod 3 is mounted on the first transmission mechanism 5, and the first transmission mechanism 5 can drive the sliding rod 3 to reciprocate between the first side portion and the second side portion of the air guiding frame 1. When the first transmission mechanism 5 drives the sliding rod 3 to move from the first side part to the second side part, the sliding rod 3 drives the filter screen 4 to be flattened on the air guide frame 1. When the first transmission mechanism 5 drives the sliding rod 3 to move from the second side part to the first side part, the filter screen 4 is wound on the scroll 2. At the same time, the scroll 2, the slide bar 3 and the filter screen 4 can be integrally detached from the air guiding frame 1 by detaching the slide bar 3 from the first transmission mechanism 5.

It will be appreciated that when the first transmission mechanism 5 drives the sliding rod 3 and the filter screen 4 to move, the reel 2 will rotate synchronously, so as to flatten the filter screen 4 on the air guiding frame 1 or wind the filter screen on the reel 2.

As shown in fig. 2 and 7, in some embodiments, the first transmission mechanism 5 further includes a first transmission gear 504, a pulley 503, and a conveyor belt 502. The first transmission gear 504 is rotatably provided at a first side portion of the air guiding frame 1. The pulley 503 is rotatably provided at the second side portion of the air guiding frame 1. One end of the conveyor belt 502 is fixed on the output shaft of the first transmission gear 504, and the other end is sleeved on the pulley 503. The connecting piece 501 is fixedly arranged on the conveying belt 502, and the conveying belt 502 can drive the sliding rod 3 to move through the connecting piece 501.

Specifically, the reel 2 rotates forward, and the conveyor belt 502 drives the sliding rod 3 to move from the first side portion to the second side portion of the air guiding frame 1 through the connecting piece 501, so as to flatten the filter screen 4 on the air guiding frame 1. The scroll 2 rotates reversely, and the conveyor belt 502 drives the slide bar 3 to move from the second side to the first side of the air guiding frame 1 through the connecting piece 501 so as to wind the filter screen 4 on the scroll 2.

It will be appreciated that the forward rotation of the spool 2 may be either clockwise or counterclockwise, and that the particular direction of rotation of the spool 2 may be adaptively adjusted based on the direction of the belt 502 about the pulley 503.

In some embodiments, as shown in fig. 7, the screen mechanism further comprises a second transmission mechanism 6. The second transmission mechanism 6 includes a base and a second transmission gear 601. The base is detachably connected with the air guiding frame 1. The second transmission gear 601 is rotatably disposed on the base, and an output end of the second transmission gear is fixedly connected with the spool 2 so as to drive the spool 2 to rotate circumferentially.

Specifically, the second transmission mechanism 6 can drive the reel 2 to rotate forward, so that the filter screen 4 is unfolded in a direction away from the reel 2 to cover the air inlet. The second transmission mechanism 6 can also drive the scroll 2 to reversely rotate, and drive the filter screen 4 to wind on the scroll 2 so as to avoid the air port. When the slide bar 3 is detached from the first transmission mechanism 5, the scroll 2, the slide bar 3 and the filter screen 4 can be integrally detached from the air guide frame 1 through the base, and the operation is simple and convenient.

It can be understood that the connection mode of the base and the air guiding frame 1 comprises screw connection and clamping connection, so long as simple disassembly and installation can be realized.

In some embodiments, as shown in fig. 7, the screen mechanism further comprises a drive mechanism 7. The drive mechanism 7 includes a drive device 702 and a drive gear 701. The driving device 702 is fixedly arranged on the air guiding frame 1. The drive gear 701 is connected to the output of the drive 702. The first transmission gear 504 is meshed with the driving gear 701, the second transmission gear 601 is meshed with the first transmission gear 504, and the driving gear 701 rotates to drive the first transmission gear 504 and the second transmission gear 601 to rotate synchronously.

Further, the first transmission gear 504 and the second transmission gear 601 are located on the same side of the driving gear 701. In this way, the movement of the reel 2 and the slide 3 can be achieved by means of a single drive 702, saving space and energy. In addition, the synchronous rotation of the first transmission gear 504 and the second transmission gear 601 can avoid the problem that the filter screen 4 is jammed or loose.

Specifically, the driving device 702 drives the driving gear 701 to rotate reversely, so as to drive the first transmission gear 504 to rotate forwardly and drive the second transmission gear 601 to rotate reversely, and further drive the spool 2 fixedly connected with the second transmission gear 601 to rotate reversely, and drive the sliding rod 3 to move in a direction away from the spool 2. Under the cooperation of the reel 2 and the slide bar 3, the filter screen 4 is moved away from the first side portion, so that the filter screen 4 spreads over the tuyere. Similarly, the driving device 702 drives the driving gear 701 to rotate forward, so as to drive the first transmission gear 504 to rotate reversely and drive the second transmission gear 601 to rotate forward, so that the reel 2 fixedly connected with the second transmission gear 601 rotates forward, and meanwhile, the conveying belt 502 fixedly connected with the output shaft of the first transmission gear 504 is gradually laid. The scroll 2 rotates positively to drive the filter screen 4 to wind on the scroll 2, and the slide bar 3 moves to the side of the scroll 2 along with the filter screen 4 so as to avoid the air port. In summary, by controlling the forward and reverse directions of the driving gear 701, the filter screen 4 can be rolled up and unrolled. The filter screen mechanism is suitable for installation of different air ports.

As shown in fig. 1, in some embodiments, the first transmission mechanism 5, the second transmission mechanism 6, and the driving mechanism 7 are two sets in number and are disposed on both sides of the spool 2.

It can be appreciated that the driving devices 702 on two sides of the spool 2 receive the same signal, so that the driving devices 702 on two sides can operate synchronously at the same frequency, so that the stress on two sides of the spool 2 is balanced, and the problems that the rotation speeds of the filter screens 4 on two ends of the spool 2 are different or rotation time differences exist are avoided.

In some embodiments, the base comprises a handle portion for carrying the reel 2, the second transmission gear 601, the slide bar 3 and the filter screen 4 to be detached integrally from the air guiding frame 1.
