  • An upper end of the outer air guide plate mounting portion 422 may be located on a front side of a lower end of the outer air guide plate mounting portion 422 (as shown in FIG. 4 , L 1 is greater than L 2 (L 1 > L 2 )), and the second pivot shaft 6 may be disposed at the outer air guide plate mounting portion 422.
  • at least a portion of the second air duct surface 421 adjacent to the second pivot shaft 6 is formed as a concave surface.
  • the airflow may run in an extending direction of the second air duct surface 421, which may ensure that the airflow runs in a direction away from a gap between the second pivot shaft 6 and the housing 1.
  • the airflow will not enter the gap between the second pivot shaft 6 and the housing 1, thereby effectively preventing the formation of the condensation on the outer air guide plate 3 and the housing 1.
  • a difference from the first embodiment is that in the air conditioner indoor unit 100 in the third embodiment, there are a first gap 14 between the first pivot shaft 5 and an inner wall of the first accommodating space and a second gap 15 between the second pivot shaft 6 and an inner wall of the second accommodating space, and a sealing strip 7 is disposed in at least one of the first gap 14 or the second gap 15.
  • the sealing strip 7 may include a first sealing strip 71, and the first sealing strip 71 includes an adhesive portion 711 and a sealing portion 712.
  • the adhesive portion 711 may adhere to the housing 1.
  • An end of the sealing portion 712 may be connected with the adhesive portion 711, and the other end of the sealing portion 712 may extend into at least one of the first gap 14 or the second gap 15.
  • the sealing strip 7 may further include a second sealing strip 72, and the second sealing strip 72 may be connected with the housing 1 in a snap-fit manner.
  • the second sealing strip 72 includes a main body 723 and a plurality of fasteners 721.
  • the plurality of fasteners 721 include a plurality of first fasteners 7211 and a plurality of second fasteners 7212 that are located at a front end of the main body 723.
  • the plurality of first fasteners 7211 are evenly spaced apart in a length direction of the main body 723, and the plurality of second fasteners 7212 are evenly spaced apart in the length direction of the main body 723.
  • the plurality of first fasteners 7211 and the plurality of second fasteners 7212 are uniformly arranged alternatively in the length direction of the main body 723.
  • the housing 1 is provided with clamping grooves 13 that are in one-to-one correspondence with the plurality of first fasteners 7211 and the plurality of second fasteners 7212.
  • a front end of each first fastener 7211 is provided with a first fastener portion 7211a, and the first fastener portion 7211a is disposed upwards.
  • the first fastener portion 7211a is provided with a first guide surface, and the first guide surface extends obliquely downwards in a direction from a rear to a front.
  • the first guide surface may guide a first fastener 7211 to enter a corresponding clamping groove 13.
  • each second fastener 7212 is provided with a second fastener portion 7212a, and the second fastener portion 7212a is disposed downwards.
  • the second fastener portion 7212a is provided with a second guide surface, and the second guide surface extends obliquely upwards in the direction from the rear to the front.
  • the second guide surface may guide a second fastener 7212 to enter a corresponding clamping groove 13.
  • the sealing strip 7 may seal the first gap 14 and/or the second gap 15, thereby preventing the airflow from entering the first gap 14 and the second gap 15, and further preventing the formation of the condensation on the housing 1, the inner air guide plate 2, and the outer air guide plate 3.
  • orientations or positional relationships indicated by terms “length”, “width”, “thickness”, “upper”, “lower”, “front”, “rear”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer”, “clockwise”, “counterclockwise”, etc. are based on orientations or positional relationships shown in the accompanying drawings, which are merely to facilitate and simplify the description of the present disclosure, but are not to indicate or imply that the referred devices or elements must have a particular orientation, or must be constructed or operated in a particular orientation. Therefore, these terms should not be construed as limitations on the present disclosure.
  • a/the plurality of means two or more.
  • a first feature being “above” or “under” a second feature may mean that the first feature and the second feature are in direct contact, or the first feature and the second feature are not in direct contact but are in contact through another feature between them.
