The indoor unit includes: a bottom case; the panel body 20 is connected with the bottom shell, and the panel body 20 is provided with an air outlet 21; the panel 30, the panel 30 is connected with the panel body 20; the first air deflector 40 is connected with at least one of the bottom shell, the panel body 20 and the panel 30, the first air deflector 40 is provided with a closed position for closing the air outlet 21 and a plurality of open positions for opening the air outlet 21 by the first air deflector 40; the second air deflector 50 is connected with at least one of the bottom case, the panel body 20 and the panel 30, the second air deflector 50 has an initial position and an air guiding position, the second air deflector 50 is located at the initial position, at least part of the second air deflector 50 is located at the bottom of the panel body 20, and when the second air deflector 50 is located at the air guiding position, the second air deflector 50 is located outside the air outlet 21.
By applying the technical scheme of the invention, the first air deflector and the second air deflector are matched, when the second air deflector is in the air guiding position and the first air deflector is in one of the opening positions, the air flow can be raised to realize upward air outlet, a lower air outlet mode is adopted during refrigeration, cold air can be prevented from blowing people directly, shower type refrigeration is realized, when the second air deflector is in the initial position and the first air deflector is in the other opening position, the air flow can be guided downwards to realize downward air outlet, and an upper air outlet mode is adopted during heating, so that carpet type heating can be realized.
Specifically, when the second air guiding plate 50 is at the initial position, one end of the second air guiding plate 50 close to the air outlet 21 is attached to the bottom of the panel body 20. As shown in fig. 1, 2 and 7, when the second air deflector 50 is at the initial position, one end of the second air deflector 50 close to the air outlet 21 is attached to the bottom of the panel body 20, and optionally, one end of the second air deflector 50 close to the air outlet 21 may be disposed beyond the lower edge of the air outlet 21. In practical applications, the position relationship between the end of the second air guiding plate 50 close to the air outlet 21 and the lower edge of the air outlet 21 can be changed as required, the length of the second air guiding plate 50 beyond the lower edge of the air outlet 21 can be changed, and the end of the second air guiding plate 50 close to the air outlet 21 can be located inside the lower edge of the air outlet 21.
Preferably, when the first air deflector 40 is in the closed position and the second air deflector 50 is in the initial position, a gap X is formed between one end of the first air deflector 40 close to the lower edge of the air outlet 21 and one end of the second air deflector 50 close to the air outlet 21, wherein X is greater than or equal to 1mm and less than or equal to 3 mm. As shown in fig. 7, the value of the gap X is set within a certain range, so that friction between the first air guiding plate 40 and the second air guiding plate 50 during movement can be avoided, and optionally, in order to have a better aesthetic effect, one end of the first air guiding plate 40 close to the lower edge of the air outlet 21 may be provided with a chamfer.
Specifically, when the second air guiding plate 50 is located at the air guiding position, a line connecting two ends of the surface of the second air guiding plate 50 facing the air outlet 21 and a vertical plane form an angle α, wherein α is greater than or equal to 60 degrees and less than or equal to 90 degrees. As shown in fig. 9, the value of the setting angle α is smaller than 90 °, so that upward air outlet can be realized when the second air guiding plate 50 is located at the air guiding position, and meanwhile, the setting of α being larger than or equal to 60 ° can avoid the influence of too small angle on the air outlet quantity.

As shown in fig. 1 and 8, when the first air guiding plate 40 is at the second opening position, the value of the limited angle β is smaller than 90 °, so that the downward air outlet effect can be realized, and meanwhile, the angle β larger than or equal to 30 ° can avoid the influence of the over-small angle on the air outlet amount.
Further, the plurality of opening positions include a first opening position, when the first air deflector 40 is located at the first opening position, an angle theta is formed between a connecting line of two ends of the surface of the first air deflector 40 facing the air outlet 21 and a vertical plane, wherein theta is larger than or equal to 90 degrees and smaller than or equal to 120 degrees. As shown in fig. 3 and 9, when the first air guiding plate 40 is in the first open position, the value of the limited angle θ is greater than 90 °, which facilitates guiding the air flow upward and realizes a better upward air outlet effect.

As shown in fig. 4 and 6, the link assembly 70 may include more than one link, and alternatively, in practical applications, the link assembly 70 may be used as a driving link, so that the driving portion directly drives the link assembly 70 to rotate, or the link assembly 70 may be used as a driven link to drive.
Further, the link assembly 70 includes: a first end of the first link 71 is connected to the middle of the first side of the second air guiding plate 50, and a second end of the first link 71 is connected to the driving part, or the second end of the first link 71 is movably connected to the panel body 20; a second connecting rod 72, wherein a first end of the second connecting rod 72 is connected to a second side of the second air guiding plate 50 close to the lower edge of the air outlet 21, a second end of the second connecting rod 72 is connected to the driving portion, or a second end of the second connecting rod 72 is movably connected to the panel body 20; the farthest distance from the connection position of the second connecting rod 72 and the panel body 20 to the side, close to the second air deflector 50, of the panel body 20 is less than the length of the second connecting rod 72.
