After the drive shaft 211 starts, give the chain or conveyer belt with power transmission, and then drive filter screen 112 and remove, consequently, based on the transmission principle of this application, no matter what kind of transmission form is selected for use by drive arrangement 200 all belongs to the scope of protection of this application.

As shown in fig. 6, in one embodiment of the present application, the sweeping means 300 includes a brush 310 for sweeping dust on the filter screen 112, a driving motor for driving the brush 310 to rotate, and a mounting bracket 330 for mounting the brush 310.

Wherein the brush 310 is always in contact with one side of the filter screen 112 when the filter screen 112 is cleaned.

The brush 310 includes a cylindrical brush rod 312, and bristles 311 disposed on an outer cylindrical surface of the brush rod 312; thus, when cleaning the filter mesh 112, as shown in fig. 5-6, the bristles 311 of the brush 310 are always in contact with the filter mesh 112.

The cylindrical brush 310 is provided so that different bristles 311 circularly clean the filter screen 112.

In the above embodiment, the brush 310 is provided with the bristles 311 which are flexible and can partially enter the filter mesh 112 (enter the gap between the filter mesh 112), so that the effective area between the brush 310 and the filter mesh 112 can be enlarged, and the filter mesh 112 can be effectively cleaned.

It should be noted that, when the filter screen 112 is cleaned, the brush 310 rotates to clean the dust on the contact portion of the filter screen 112, and different portions of the filter screen 112 are respectively contacted with the brush 310 by the movement of the filter screen 112, so that the dust on the filter screen 112 is separated from the filter screen 112, and finally the filter screen 112 is cleaned; therefore, the brush 310 only needs to rotate when cleaning, and is not used for moving along the filter screen 112 in the machine shell, but the filter screen 112 is moved, so that different parts of the filter screen 112 are in contact with the brush 310.

Compared with the scheme that the brush 310 moves for cleaning, the driving device 200 of the utility model is simpler and occupies smaller space in the machine shell.

The driving means 200 drives the filter net 112 to horizontally move leftward or rightward, and the brush 310 is horizontally disposed in the front-rear direction. In this way, the height of the housing in the vertical direction is slightly increased by providing the driving device 200 and the cleaning device 300, but the thickness of the housing in the front-rear direction is not increased, so that the whole air conditioner is not heavy.

The driving shaft 211 driving the filter screen 112 to move and the brush 310 in the cleaning device 300 are respectively disposed at the upper and lower sides of the filter screen 112, and are disposed in a staggered manner in the vertical direction, so as to ensure that the filter screen 112 moves more stably and reliably.

As shown in fig. 6, in one embodiment of the present application, the sweeping device 300 further includes a dust removing comb 331.

In an embodiment of the present application, one side of the dust removing comb 331 is provided with a plurality of flexible thin sheets as comb teeth of the dust removing comb 331, the comb teeth can be made of rubber, and the other side of the dust removing comb 331 is fixed on the mounting frame 330.

The dust removing comb 331 is fixedly installed on the mounting frame 330, the dust removing comb 331 is disposed opposite to the brush 310, and the teeth of the dust removing comb 331 face the brush 310, and are configured to scrape off dust attached to the brush 310 by continuously interfering with the dust removing comb 331 during the rotation of the brush 310.

When the cleaning device 300 is cleaned, the filter screen 112 is cleaned by the rotation of the hairbrush 310, the dust is attached to the hairbrush 310, rotates along with the hairbrush 310, and is combed by the dust removing comb 331, so that the dust attached to the hairbrush 310 is combed off and falls into the dust collecting box 400 below the hairbrush 310; the dust on the fur brush 310 is combed cleaner by arranging the dust removing comb 331, so that the cleaning speed and the cleaning effect are improved.

Of course, when the brush 310 rotates to clean the filter screen 112, some dust may fall into the dust collecting box 400 after being directly separated from the filter screen 112; meanwhile, part of dust floats in the air at the brush 310, and the floating dust is mainly concentrated at the fixed position of the brush 310 in the machine shell due to the rotation of the brush 310, so that the dust is prevented from floating in the machine shell in a large area; and the dust box 400 is located under the brush 310, and finally most of the floating dust falls into the dust box 400. Therefore, the separated dust is prevented from falling on other parts in the machine shell again in the cleaning process.

Based on the two embodiments, the position of the brush 310 is fixed, the bristles 311 reaching the contact position with the filter screen 112 contact the filter screen 112 in the rotation process of the brush 310, because the bristles 311 are arranged on the outer cylindrical surface of the brush rod 312, the bristles 311 continuously reach the contact position with the filter screen 112 all the time, the bristles 311 on the brush 310 always contact the filter screen 112, and the bristles 311 leave the filter screen 112 to comb off dust after the dust is attached to the bristles 311, so that the cleaning efficiency is high, and the cleaning is clean.

Similarly, the brush hairs 311 clean the filter screen 112 and adhere to dust, and then rotate toward the dust removing comb 331 under the driving of the rotation of the brush rod 312, the brush hairs 311 contact with the dust removing comb 331, at this time, the brush rod 312 rotates and then has the brush hairs 311 to clean the filter screen 112, and the brush hairs 311 always contact with the dust removing comb 331 to comb off the adhered dust.

In other embodiments of the present application, in order to improve the cleaning efficiency of the fur brush 310, two dust removing combs 331 may be provided, and the two dust removing combs 331 are disposed opposite to each other and are in contact with the fur brush 310.

The brush 310 cleans the surface of the filter screen 112, and the dust removing comb 331 makes the dust attached to the bristles 311 fall off completely after the filter screen 112 is cleaned, so that the cleaning capability of the bristles 311 is increased, and the cleaning speed of the filter screen 112 is increased.

In some embodiments of the present application, the screen enclosure frame 111 is provided with an optoelectronic assembly (not shown in the figures) at one end.

The photoelectric assembly is used for confirming the cleaning position of the filter screen 112 so as to confirm the number of times of cleaning and the cleaning time, and whether the filter screen 112 is normally reset.

controlling the motion mode of the driving motor according to the current motion information of the filter screen 112 transmitted by the photoelectric component;

when the cleaning device 300 is in a cleaning state, the electric control unit controls the movement direction of the filter screen 112 and the rotation direction of the brush 310 to be opposite to the movement direction of the tangent position of the filter screen 112 and the brush 310, and the two move relatively, so that the joint time of the brush 310 and the filter screen 112 is increased, the contact stress between the two is increased, and the cleaning efficiency of the brush 310 is improved.

When the filter screen 112 is blocked in the moving process, the electronic control unit controls the moving direction of the filter screen 112 to be the same as the moving direction of the brush 310 at the tangent position of the filter screen 112 and the brush 310, so as to play a role in assisting to drive the filter screen 112 to move in the rotating process of the brush 310.
