The middle air guide plate 62 is rotatably connected to the middle rotating shaft 61, and the middle air guide plate 62 can swing 360° in the left and right directions around the middle rotating shaft 61.

[0028] The upper air guide assembly 7 includes an upper rotating shaft 71 and an upper air guide plate 72. The upper air guide plate 72 is rotatably connected to the upper rotating shaft 71, and the upper air guide plate 72 can swing around the upper rotating shaft 71 in the left and right directions.

[0029] A first air outlet passage is provided between the upper air guide plate 72 and the middle air guide plate 62 , and a second air outlet passage is provided between the middle air guide plate 62 and the upper air guide plate 72 ;

[0030] When the indoor unit is in the closed state, the right side of the lower air guide plate 52 and the left side of the middle air guide plate 62 can be separated and overlapped together, and the right side of the middle air guide plate 62 and the left side of the upper air guide plate 72 can be separated and overlapped together, so that the air outlet 4 is sealed;

[0031] A lower air guide plate placement cavity 21 is provided in the bottom frame 2, and the lower air guide plate 52 can be rotated into the lower air guide plate placement cavity 21, and the lower air guide plate 52 can be matched and set in the lower air guide plate placement cavity 21; an upper air guide plate placement cavity 31 is provided in the middle frame 3, and the upper air guide plate 72 can be rotated into the upper air guide plate placement cavity 31, and the upper air guide plate 72 can be matched and set in the upper air guide plate placement cavity 31.

[0032] When the indoor unit of the wall-mounted air conditioner of the present invention is in operation, by controlling the rotation of the lower air guide plate 52 of the lower air guide assembly 5, the rotation of the middle air guide plate 62 of the middle air guide assembly 6, and the rotation of the upper air guide plate 72 of the upper air guide assembly 7, a first air outlet channel of different shapes is formed between the upper air guide plate 72 and the middle air guide plate 62, and a second air outlet channel of different shapes is formed between the middle air guide plate 62 and the upper air guide plate 72, thereby forming a variety of air guide effects, forming air outlet effects in different directions, such as Figures 2 to 5 As shown, the comfort of the air conditioner is effectively improved, thereby improving the user experience.

[0033] In order to facilitate the rotation of the lower air guide plate 52, the middle air guide plate 62, and the upper air guide plate 72 and improve the air guiding effect, the middle air guide assembly 6 is arranged at the upper right of the lower air guide assembly 5, and the lower air guide assembly 5 is arranged at the upper right of the middle air guide assembly 6. Furthermore, the cross-sectional shape of the lower air guide plate 52 and the cross-sectional shape of the upper air guide plate 72 are both fan-shaped, and the cross-sectional shape of the middle air guide plate 62 is a quadrilateral. The fan-shaped lower air guide plate 52 and the upper air guide plate 72 can also ensure their own strength and increase their service life.

[0034] For example Figures 2 to 5 As shown, the right side of the lower air guide plate 52, the upper surface and lower surface of the middle air guide plate 62, and the left side of the upper air guide plate 72 are all air guiding surfaces. In order to ensure the air guiding effect, the right side of the lower air guide plate 52 is a smooth plane, the upper surface and lower surface of the middle air guide plate 62 are both smooth planes, and the left side of the upper air guide plate 72 is a smooth plane.

[0035] In order to further improve the appearance of the indoor unit, the gap between the lower air guide plate 52 and the middle air guide plate 62, and the gap between the middle air guide plate 62 and the upper air guide plate 72 are reduced. Figure 1As shown, when the indoor unit is in the closed state, the right side of the lower air guide plate 52 and the left side of the middle air guide plate 62 are detachably overlapped in a stepped manner, that is, the right side of the lower air guide plate 52 is arranged above the left side of the middle air guide plate 62, and the right side of the middle air guide plate 62 and the left side of the upper air guide plate 72 are detachably overlapped in a stepped manner, that is, the left side of the upper air guide plate 72 is arranged above the right side of the middle air guide plate 62. Furthermore, when the indoor unit is in the closed state, the left side of the middle air guide plate 62 is an inclined surface, and the right side of the lower air guide plate 52 overlaps on the inclined surface; a positioning groove 621 is arranged on the middle air guide plate 62, and a positioning protrusion 721 is arranged on the left side of the upper air guide plate 72, and the positioning protrusion 721 is matched and arranged at the positioning groove 621.

[0036] When the indoor unit is operating in cooling mode, Figure 2 As shown, in order to increase the size of the first air outlet channel and the second air outlet channel, the lower air guide plate 52 is rotated to the lower air guide plate placement cavity 21, the upper air guide plate 72 is rotated to the upper air guide plate placement cavity 31, and the middle air guide plate 62 is rotated to a horizontal state, so that the refrigeration air flow is sent out horizontally, and the horizontal coverage of the refrigeration cold air is increased. Although this refrigeration mode can improve the air supply effect, after running for a certain period of time, an air supply isolation area will be formed in the area below the middle air guide plate 62. The air supply isolation area is an air gathering area with ambient humidity, which will cause the middle air guide plate 62 to be in a state of alternating hot and cold, resulting in condensation on the lower surface of the middle air guide plate 62. In order to solve this problem, after the present invention runs in the cooling mode for a certain period of time or through the temperature and humidity detection input of the air conditioner, if the environment of the middle air guide plate 62 is in an environment with a certain humidity, the lower air guide plate 52 is controlled to swing to the right, so that the air outlet of the first air outlet channel blows to the lower area of ​​the middle air guide plate 62, thereby blowing away the air with ambient humidity in the air supply isolation area, effectively avoiding the problem of condensation on the lower surface of the middle air guide plate 62.
