As an alternative embodiment, as shown in fig. 7, the winding portion 23 includes a winding roller and an adsorption layer disposed on the surface of the winding roller, and the winding roller is in transmission connection with the driving assembly 21. The filter screen 3 can be wound along the wall of the drum under the adsorption (adhesion) action of the adsorption layer.

As an alternative embodiment, the absorption layer is a hook and loop fastener or a hard brush, and can reliably act on the filter screen 3 to drive the filter screen to rotate.

As an alternative embodiment, as shown in fig. 4, the severing member 24 comprises a plurality of jaws running axially along the winding 23, having a tough portion, all of which are close to the winding 23.

As an alternative embodiment, one side of the storage box 22 close to the winding part 23 is provided with an opening, so that the cut dirty filter screen can fall into the storage box 22 by gravity.

As an alternative embodiment, the screen placing unit 1 includes a screen slot 11 having an opening at one side, and the clean screen 3 can be placed in the screen slot 11 through the opening. The clean filter screen 3 can adopt a roller winding structure and a folding structure.

The utility model also provides a filter screen 3 component, which comprises a filter screen 3 and any one of the filter screen folding and unfolding structures; the clean filter screen 3 is arranged on the screen placing unit 1, the free end of the clean filter screen 3 can be dragged and dropped along the length direction of the air inlet to extend to the winding unit 2 to be limited and at least cover the air inlet, and the purpose of effective filtering is achieved.

As shown in fig. 3-6, the present invention further provides an air-conditioning indoor unit, which comprises a casing 5, an air inlet grille 4 and the filter screen assembly, wherein the net releasing unit 1 and the winding unit 2 are disposed on the casing 5 and located at two ends of the air inlet. The air inlet grille 4 is detachably mounted on the top side of the housing 5. When the filter screen 3 is disassembled or replaced, the air inlet grille 4 is only needed to be disassembled, so that the clean filter screen 3 can be conveniently placed into the open type screen placing unit 1 or the dirty filter screen can be conveniently taken out from the open type rolling unit 2, and the disassembly and the replacement are convenient and fast.

In an alternative embodiment, the storage box 22 of the rolling unit 2 is detachably mounted on the housing 5, and the storage box 22 is directly taken out when the dirty filter screen is to be taken out, so that the dirty filter screen can be taken out and discarded more conveniently; storage cassette 22 may specifically be snap fit, or may be a pull and pull type.

The filter screen 3 is made of flexible materials, and is easy to wind along the length direction of the whole air conditioner under the driving of the driving mechanism.

As shown in fig. 3 and 4, the filter screen retracting structure has a screen releasing end (screen releasing unit 1) and a winding end (winding unit 2), and the distance between the screen releasing end and the winding end at least completely covers the air inlet of the air conditioner. The net placing end is a clean filter net 3 (the shape of the clean filter net 3 is not limited, the patent takes a roller shape as an example, and the net placing end can also be in other folding shapes). The clean filter screen 3 is stored in the cavity at the side of the air inlet of the air conditioner. The rolling end is the cylinder structure, covers the magic subsides on the cylinder (can also be scrubbing brush or other structures that can adsorb filter screen 3), and rolling end accessible motor or other drive arrangement drive its rotation to the filter screen 3 rotation of drive absorption above that will clean filter screen 3 is followed from putting the net end and is followed air conditioner air intake length direction and pull out.

The mechanism is retrieved to filter screen 3 comprises jack catch and receiver 22. When rolling end drive dirty filter screen move to contact with the jack catch, the jack catch is served from the rolling and is decided dirty filter screen and scrape down, falls into receiver 22 of below.

As shown in FIG. 6, when the user supplements the clean filter screen, the user only needs to put the clean filter screen 3 into the cavity on the side of the air inlet, and pull the clean filter screen along the length direction of the air inlet to be attached to the winding end. Meanwhile, the storage box 22 is pulled out, and the dirty filter screen is discarded and the storage box 22 is mounted again (the storage box 22 and the shell 5 adopt an elastic buckle or other easily-detachable matching structures).

The utility model also provides an air conditioner, machine in the above arbitrary air conditioning.

After the filter screen assembly, the air conditioner indoor unit and the air conditioner adopt the filter screen folding and unfolding structure, the filter screen 3 is easy to disassemble and replace, and the air filtering effect is effectively guaranteed. In addition, the phenomena of peculiar smell, mildew and the like caused by the fact that the dirty filter screen is not easy to take out are avoided.

The utility model provides a filter screen of air conditioner changes control method includes:

determining the service time of a filter screen at an air inlet of an air conditioner, and comparing the service time with a preset threshold value;

when the service time is longer than the preset threshold value, the driving component is started or the limit of the limit structure is cancelled, and the filter screen 3 moves from the screen releasing unit 1 to the winding unit 2 to complete the update of the filter screen at the air inlet.

Specifically, the filter screen 3 replacement control method is as shown in fig. 8, and the detection device (a time detection device, such as a timer, which performs replacement when the filter screen 3 reaches a certain service time, or an infrared detection device which detects a filthy blockage of the filter screen 3 and performs replacement when the filter screen 3 is filthy blocked) determines the service time of the filter screen 3 at the air outlet, and if the service life is not reached (is less than a preset threshold value), the filter screen 3 continues to be used without being replaced temporarily. When the service life is reached, a motor or other driving devices at the rolling end drive the rolling end to rotate, the dirty filter screen is recovered, and meanwhile, the clean filter screen is pulled out, and the filter screen 3 is automatically replaced; and during the period, judging whether the clean filter screen completely covers the air inlet, and when the clean filter screen 3 completely covers the air inlet, stopping the rotation of the winding end. Every time the automatic replacement of filter screen 3 is accomplished, all need detect and put net end clean filter screen 3 and whether change next time, if not enough (adopt distance sensor, be used for detecting the distance of putting net end filter screen 3 distance sensor, when the distance is less than the default, the sign needs to be changed), then send the warning, remind the user to supply filter screen 3.

The utility model realizes the easy supplement and replacement of the filter screen; the filter screen is not easy to mildew and generate peculiar smell; and simple structure, the reliability is high.
