[0005] To solve the above problems, the present invention provides a filter assembly, which is arranged at the air inlet of an air conditioner. The filter assembly comprises: a filter body; an air inlet grille is arranged on the side wall of the filter body; and a lifting structure. The filter body is driven by the lifting mechanism and has an air intake state and a dustproof state. The air intake state refers to that the filter body extends out of the air conditioner to reveal the air inlet grille, and the dustproof state refers to that the filter body is retracted into the air conditioner to hide the air inlet grille.

[0006] Compared with the prior art, the technical effect achieved by adopting this technical scheme is as follows: the filter assembly is arranged at the air inlet to collect dust at the air inlet of the air conditioner to prevent dust from entering the air conditioner; the air inlet grille can filter the air and collect dust; the filter body can be lifted and lowered by a lifting structure; when the air conditioner is not turned on, in order to avoid the air inlet grille being exposed to the external environment for a long time and collecting unnecessary dust, the filter body enters a dust-proof state, and the filter assembly moves toward the inside of the air conditioner through the lifting structure to hide the air inlet grille; when the air conditioner is turned on, the air inlet needs to enter the air inlet, and the filter body enters an air inlet state; the filter assembly moves toward the outside of the air conditioner through the lifting structure to expose the air inlet grille, so that the air inlet grille can normally collect dust at the air inlet; at the same time, during the lifting and lowering process of the filter body, the cleaning device can clean the air inlet grille to ensure the smoothness of the air inlet of the air inlet grille, further prevent the problem of dust accumulation at the air inlet grille, and solve the problem of difficult manual cleaning.

The air inlet grille 111 can filter the air and collect dust. The filter body 110 can be lifted and lowered by a lifting structure (not shown in the figure). When the air conditioner 200 is not turned on, in order to avoid the air inlet grille 111 being exposed to the external environment for a long time and collecting unnecessary dust, the filter body 110 enters a dustproof state, and the filter assembly 100 moves to the inside of the air conditioner 200 through the lifting structure (not shown in the figure) to hide The air inlet grille 111, when the air conditioner 200 is turned on, the air inlet port 210 needs to take in air, and the filter body 110 enters the air intake state. The filter assembly 100 is moved to the outside of the air conditioner 200 through a lifting structure (not shown in the figure) to expose the air inlet grille 111, so that the air inlet grille 111 can normally collect dust at the air inlet port 210. At the same time, during the lifting and lowering process of the filter body 110, the cleaning device 120 can clean the air inlet grille 111 to ensure the smoothness of the air intake of the air inlet grille 111, further prevent the problem of dust accumulation at the air inlet grille 111, and solve the problem of difficult manual cleaning.

[0047] It should be noted that the air inlet grille 111 is surrounded and limited to collect dust around the air inlet space 116, thereby increasing the dust collecting area of ​​the air inlet grille 111 and increasing the air intake of the air inlet grille 111. The cleaning device 120 covers at least one side of the air inlet space 116. The cleaning device 120 covers the air inlet grille 111 in the length direction and can completely clean the air inlet grille 111, thereby improving the dust cleaning ability at the air inlet grille 111 and preventing dust from accumulating at the air inlet grille 111, thereby avoiding the situation where the air intake of the air inlet grille 111 is generally weakened.

[0048] In a specific embodiment, the air inlet grille 111 includes: a plurality of vertical ribs 117 and transverse ribs 118 ; the vertical ribs 117 are arranged at intervals in the air inlet grille 111 , and the transverse ribs 118 and the vertical ribs 117 surround and define a plurality of air inlet units 119 .
