[0040] See also Figure 1 As shown, according to an embodiment of the present invention, a housing assembly is provided, which includes a housing 1, a filter assembly 2, and a dust removal assembly 3. The housing 1 has an air inlet and an air outlet. The filter assembly 2 is detachably connected to the housing 1 and has a first position located at the air inlet and a second position located at the air outlet. The dust removal assembly 3 is located near the air outlet and is detachably connected to the housing 1. When the filter assembly 2 is located in the second position, the dust removal assembly 3 cleans the dust that falls on the filter assembly 2.

[0041] When the indoor unit is not in use, the filter assembly 2 is in the first position, serving to shield against dust. When the indoor unit is in use, the filter assembly 2 is in the second position, and the dust removal assembly 3 contacts the filter assembly 2 to clean the dust that has fallen on it. In this invention, the filter assembly 2 is in the second position, and the dust removal assembly 3 cleans the filter at the air outlet. After cleaning, the filter assembly 2 disperses the airflow from the indoor unit, controlling the direct flow of cold air and solving the problem of uncomfortable cold air blowing into small bedrooms.

[0042] In this embodiment, the filter assembly 2 includes a movable baffle 201 and a filter body 202. The filter body 202 is fixedly connected to the movable baffle 201. The movable baffle 201 has an open position and a closed position. When the movable baffle 201 is in the open position, the filter body 202 is in the second position; when the movable baffle 201 is in the closed position, the filter body 202 is in the first position.

[0043] Specifically, the movable baffle 201 is made of flexible material and can be bent at a certain angle to move inside the housing 1. When the air conditioner is not in use, the movable baffle 201 is in the closed state, blocking the air inlet. The filter body 202 does not move, and the movable baffle 201 serves to block dust, preventing dust from entering the interior of the housing 1. When the air conditioner is in use, the movable baffle 201 moves inside the housing 1, causing the filter body 202 to move. The filter body 202 moves to the second position at the air outlet, dispersing the air blown out by the air conditioner.

[0044] See also Figure 2 As shown, it also includes a first driving component 4, which is connected to the movable baffle 201. The first driving component 4 can drive the movable baffle 201 to be in the open or closed position.

[0045] In one specific implementation, the first drive assembly 4 includes a mounting base 401, a first motor 402, a rack 403, a drive gear 404, a driven gear 405, and a connecting arm 406. The mounting base 401 is mounted on the housing 1. The first motor 402 and the rack 403 are mounted on the mounting base 401. The drive gear 404 is sleeved on the output shaft of the first motor 402. The driven gear 405 meshes with the rack 403 and the drive gear 404 respectively. A curved slide rail is provided on the rack 403. The two ends of the connecting arm 406 are connected to the rack 403 and the movable baffle 201 respectively. When the first motor 402 is working, the drive gear 404 and the driven gear 405 rotate, causing the rack 403 to move along the slide rail. The movable baffle 201 drives the filter screen body 202 to move. It is worth noting that the moving distance of the rack 403 in this invention is matched with the moving distance of the filter body 202, that is, the moving distance of the rack 403 is at least enough to move the filter body 202 to the air outlet.

[0046] See also Figure 3 and Figure 4 As shown, the dust removal assembly 3 includes a dust collection box 301 and a roller brush 302. The dust collection box 301 is connected to the housing 1. The dust collection box 301 has a dust collection port on the side facing the filter body 202. The roller brush 302 is disposed inside the dust collection box 301, and its outer surface is in contact with the filter body 202. When the first motor 402 operates, the filter body 202 moves to the air outlet. The roller brush 302 cleans the dust on the filter body 202. During the rotation of the roller brush 302, the dust falls into the dust collection box 301, thus achieving the cleaning of the filter body 202 and the collection of dust.

[0047] Referring to Figure 3, the dust removal assembly 3 includes a dust collection box 301 and a roller 303. The dust collection box 301 is connected to the housing 1, and has a dust collection port on the side facing the filter body 202.

Depending on cleaning needs, when the movable baffle 201 needs cleaning, the roller brush 302 can be replaced with the roller 303. The roller 303 has an adhesive surface and cleans the dust on the movable baffle 201. Specifically, the roller 303 has adhesive stickers attached, which can absorb and clean dust, lint, and other substances from the filter body 202 or the movable baffle 201. To prevent dust from falling and from accumulating more dust after the brush scratches the movable baffle 201, the roller brush 302 is replaced with a roller 303. The adhesive sticker on the roller 303 can collect the dust on the movable baffle 201. After a certain period of time, the entire roller 303 is disassembled and replaced.

[0048] As one specific implementation method, see [link to relevant documentation] Figure 6As shown, the bottom of the housing 1 is provided with an openable cover 7. The dust collection box 301 is snapped to the housing 1. If too much dust is collected in the dust collection box 301, the cover 7 can be opened to remove the dust collection box 301 for cleaning. Specifically, the dust collection box 301 can be automatically lowered out by a traction rope for easy removal by the user. The cover 7 can be equipped with an automatic opening device. After prolonged use, the roller brush 302 can also be removed from the dust collection box 301 and replaced with a new roller brush 302. Alternatively, the roller brush 302 can be replaced with a roller 303 to achieve zoned cleaning of the filter assembly 2. The dust collection box 301, roller brush 302, and roller 303 are all detachable structures, making them flexible in use and easy to replace and clean.

[0049] See also Figure 5 As shown, the dust removal assembly 3 also includes a second motor, which is mounted on the dust collection box 301 and connected to the roller brush 302 or the drum 303. A baffle 304 is provided at the dust collection port to scrape dust from the roller brush 302 into the dust collection box 301. During the movement of the filter body 202, the roller brush 302 or the drum 303 will rotate. The second motor drives the roller brush 302 or the drum 303 to rotate, making it easier for dust to fall into the dust collection box 301 and meeting stronger cleaning requirements. During the rolling of the roller brush 302, the baffle 304 scrapes the dust from the roller brush 302 into the dust collection box 301.

[0050] The housing 1 is provided with an inner opening panel 5, which is located inside the air guide plate. When the air guide plate is opened, the inner opening panel 5 can be opened to see whether the filter body 202 needs to be cleaned and whether the roller brush 302 needs to be replaced, making it easier to determine whether the dust has been cleaned properly.

[0051] A filter screen track 101 is provided on the side wall of the housing 1, and the filter screen body 202 can move along the filter screen track 101 to a first position or a second position. A filter screen replacement port 102 is provided on the housing 1. After opening the inner layer opening panel 5, the moving baffle 201 and the filter screen body 202 are pulled out from the filter screen replacement port 102. When installing a new filter screen body 202, the moving baffle 201 and the filter screen body 202 are installed along the filter screen track 101. The filter screen is provided with installation teeth to facilitate the movement of the filter screen body 202 along the filter screen track 101.

[0052] As a specific implementation method, the dust removal component 3 can be selectively moved according to the size and layout of the indoor unit. Specifically, a second drive component 6 is provided on the housing 1. The second drive component 6 has the same structure and operation as the first drive component 4, and is snap-fitted to the dust collection box 301. When it is necessary to adjust the position of the dust collection box 301, the roller brush 302, or the roller 303, the second drive component 6 operates to adjust the position, meeting the dust cleaning needs of the filter body 202 or the movable baffle 201 at different positions.
