The front side of the lower case 23 allows at least a portion of the outer side surface of the dust screen 600 to be exposed so that the dust screen 600 is in contact with the dust removing drum brush 41. That is, most of the mesh cloth of the dust filter 600 is located inside the filter box 20 and inside the frame defined by the upper box 22 and the lower box 23, so as to avoid interference with other structures inside the indoor unit, thereby ensuring normal operation of the heat exchange system of the indoor unit and the cleaning device 200. The front side of the lower case 23 allows the bottom of the dust screen 600 in any rotational position to be exposed to the outside of the screen case 20, thereby facilitating the contact of the rotating dust screen 600 with the dust removing roller brush 41 to effect the cleaning of the screen.
In some embodiments of the present invention, the dust filter 600 may have both the frame and two driving racks respectively disposed on two longitudinal frames of the lateral outer side thereof. It should be noted that, as will be understood, the longitudinal frame herein refers to a frame extending in the longitudinal direction on the left and right sides of the dust screen 600 when the dust screen is naturally unfolded in a plane. The two transmission racks of the dust screen 600 are configured to mesh with the two first transmission gears 32 of the transmission rod 31, respectively.
In some embodiments of the present disclosure, the screen box 20 may further include a cover 26 configured to be pivotally disposed on the upper box 22 or the inner box 24. The gland 26 is controlled to rotate rearwardly to a closed position to compress the dust screen 600 towards the drive rod 31 so that the drive rack engages the first drive gear 32. The gland 26 is also controllably rotated forward to an open position to allow the dust screen 600 to be disengaged from the screen cartridge 20. That is, the rotation of the pressing cover 26 to the predetermined position causes the dust filter 600 to be engaged with the transmission structure 25, so that the dust filter 600 is moved by the transmission structure 25. When the indoor unit and the cleaning device 200 are in normal operation, the pressing cover 26 rotates backward to press the frame of the dust filter 600, so that the driving racks on both sides of the pressing cover are engaged with the first driving gear 32, thereby ensuring the stable rotation of the dust filter 600. When the dust filter 600 needs to be removed for replacement or cleaning, the pressing cover 26 can be controlled to rotate forward to separate the transmission rack from the first transmission gear 32, so that a user can conveniently draw out the dust filter 600 from the lower part of the filter box 20, and the replacement operation of the dust filter 600 is simplified. Further, the inside of the pressing cover 26 may be provided with rails or guide rails, respectively, to ensure smooth sliding and rotation within the sieve box 20 while pressing the dust screen 600.
In some embodiments of the present invention, referring to fig. 7 and 8, the dust removing roller brush 41 is disposed inside the dust removing box 40 in a lateral direction. The dust removing rolling brush 41 includes a rotating shaft, one end of which is provided with a second transmission gear 42, and the second transmission gear 42 is engaged with an output gear of the gear transmission mechanism.
The dust removal cartridge 40 may include a cartridge base and a cartridge bottom cover 46. The cassette holder is configured to extend in the transverse direction of the indoor unit and has a front wall 43, an upper wall, a rear wall 44 and side walls 45. The upper end of the front wall 43 is higher than the upper wall to abut against the sieve box 20. The upper wall has a relief strip-shaped hole to allow the dust removing roller brush 41 to contact the dust filter 600. The rear end of the box bottom cover 46 is rotatably connected to the lower end of the rear wall 44, and the front end of the box bottom cover 46 is engaged with the lower end of the front wall 43. Still set up the comb structure in the dust removal box 40, scrape the dust on the round brush 41 that removes dust, box bottom cover 46 and box seat are through pivot and buckle cooperation, and the user can open the washing with dust removal box 40 after taking out dust removal box 40.
Further, the rotation process of the dust filter 600 is as follows: when the cleaning device 200 receives an instruction to clean the dust filter 600, the gear box 50 can be started under the control of the indoor unit main control board and other devices to drive the transmission rod 31 to rotate in the first direction to further drive the dust filter 600 to rotate downward and backward from the panel and the inner side of the air inlet, so that at least part of the dust filter 600 gradually separates from the first track and enters the second track. After the mesh of the dust filter 600 moves to the preset position, the gear box 50 can change the direction of the output force under the control of the main control board, so that the transmission rod 31 is controlled to rotate in the second direction, and the dust filter 600 is driven to enter the first track from the second track and return to the initial position covering the air inlet, thereby completing a rotation cycle of the dust filter 600. In the rotation period, the dust filter 600 will make two different direction contacts with the dust removing rolling brush 41 when passing through the lower part of the transmission rod 31 in two times of rotation, so as to clean the dust filter 600. In some alternative embodiments of the present invention, the track may be an annular track, i.e. the dust filter 600 can move around a direction, and move along the track from the position covering the air inlet, and continue to move to the initial position covering the air inlet along the direction after being cleaned by the dust removing rolling brush 41.
The utility model also provides an air conditioner indoor unit, as shown in fig. 1 to 8, indoor unit internally mounted has above-mentioned cleaning device 200 and corresponding dirt filtrating screen 600 in order to clean indoor ambient air. The number of the cleaning devices 200 can be determined according to the length of the indoor unit and the length of the cleaning device 200. For example, the cleaning devices 200 may be two, which are sequentially disposed in the lateral direction of the indoor unit to cover the left and right portions in the lateral direction of the indoor unit, respectively.
In some embodiments of the present invention, the dust box 40 may be configured to be drawn out or inserted from the front and rear direction of the indoor unit. Specifically, in this embodiment, the indoor unit includes a casing 100. For example, enclosure 100 may include a housing and skeleton 110, and the like. The housing has a front panel 120, and the frame 110 may be provided with laterally extending, forwardly opening mounting slots to allow the dust box 40 to be inserted therein in a front-to-rear direction. The mounting groove is closed by a front wall 43 of the dust-removing box 40 when the dust-removing box 40 is inserted. After the dust box 40 is installed in the indoor unit, the dust box 40 can be fixed in the indoor unit by the stopper 47 and the second transmission gear 42 is engaged with the output gear of the gear box 50.
