Fig. 5 is a schematic structural diagram of a frame 300 according to an embodiment of the present invention.

In some embodiments of the present invention, referring to FIG. 5 , at least one liquid guide plate 700 is provided on the rear wall of the casing, and the liquid guide plate 700 is configured to extend obliquely downward from its middle position and extend to both lateral ends respectively, so as to Directs condensation that forms on the rear wall of the enclosure to flow to the sides of the enclosure. That is to say, after being swept away by the cleaning brush 501, the dust and other pollutants accumulated on the purification module 403 will float down to the rear wall of the casing, and can be further washed by the condensed water formed on the rear wall to the liquid guide. Plate 700, and the condensed water is discharged from the drain pipe. As a result, there is no need to add additional cleaning or flushing structures, and the automatic cleaning operation of the purification assembly 400 can be completed only through the original structure inside the air-conditioning indoor unit 1, simplifying the air-conditioning indoor unit 1 with the automatic cleaning purification assembly 400 internal structure.

Referring to FIG. 5 , in some embodiments of the present invention, the cleaning device may further include a dust collection channel 502 . The dust collection channel 502 is disposed below the cleaning brush 501 to collect the dust falling from the outer surface of the cleaning assembly 400 and guide it to the liquid guide plate 700 . In this way, the gas flow in the casing can prevent the dust from falling to other positions in the casing, and the reliability of the cleaning device for cleaning the purification assembly 400 is enhanced.

In some embodiments of the present invention, the dust collection channel 502 can be configured to extend along the lateral direction of the casing, so as to correspond to the length of the cleaning brush 501 in the lateral direction. The dust collection channel 502 includes an upper section and a lower section which are connected. The upper section extends obliquely backward and downward from the second rotating shaft 402 to the rear wall of the casing. The lower section extends downward from the bottom end of the upper section to the liquid guide plate 700 along the rear wall of the casing. As a result, the dust swept off by the cleaning brush 501 can be collected and guided to the rear wall of the casing, preventing it from falling to other structures or devices inside the casing, affecting the cooling/heating effect of the air conditioner or causing malfunctions.

Specifically, in some embodiments of the present invention, the top end of the upper section has an upper opening that allows dust to fall into it, and the front side edge of the upper opening is located at the front side below the axis of the second rotating shaft 402, and the upper opening The rear edge of the is located on the rear side below the brush head. The bottom end of the lower section has a lower opening that allows dust to fall on the liquid guide plate 700. The projections of the front edge and the rear edge of the lower opening in the vertical direction all fall on the liquid guide plate 700, and the lower opening At least part of the rear side edge of the liquid guide plate 700 abuts against.

That is to say, the upper part of the dust collection passage 502 is a passage extending obliquely downward from the upper part in the casing, and the lower half is a passage extending substantially vertically at the rear part in the casing, so that the dust collection passage 502 can be formed into a shape that is roughly attached to the inner wall of frame 300 , so as to avoid interference with the internal structure of air-conditioning indoor unit 1 such as heat exchange devices and fans disposed in the space defined by frame 300 and casing 200 . Further, the width of the upper opening at the top of the upper section of the dust collection channel 502 (that is, the dimension in the thickness direction of the air conditioner indoor unit 1) can be configured to be no less than the distance from the second rotating shaft 402 to the mounting seat of the cleaning brush 501, Therefore, it can be ensured that all the dust swept down by the purification module 403 can directly enter the dust collection channel 502 through the upper opening. In addition, the lower opening at the bottom of the lower section of the dust collection channel 502 is located directly above the liquid guide plate 700, and the outer channel wall (ie, the rear side edge of the lower opening) extends downward until it contacts the liquid guide plate 700, This can ensure that the dust in the dust collection channel 502 can fall onto the liquid guide plate 700 , mix with the condensed water on the liquid guide plate 700 and be discharged to both sides.

In some embodiments of the present utility model, there may be multiple liquid guide plates 700, and the multiple liquid guide plates 700 are all configured such that their middle positions are higher than the two ends and extend downwards, extending to the left and right sides respectively, and extending from the top to the left. Arranged in sequence downwards, the liquid guide plate located on the lower side can be configured to be slightly longer than the liquid guide plate located above it. Thus, it can be further ensured that the dust falling from the dust collection channel 502 and/or the condensate flowing down the rear wall of the casing are all intercepted on the multi-layer liquid guide plate and exported to both sides, so that the purification function of the air conditioner indoor unit 1 It is more stable and the purification effect is better.
