Referring to fig. 1 to 32, according to an embodiment of the present application, an indoor unit is provided.

The indoor unit includes: the wind sweeping device comprises a bottom shell 10, a wind sweeping assembly 20, a shielding assembly 30 and a driving assembly 40. The bottom case 10 has an air outlet channel 11 and an accommodating space 12 communicated with the air outlet channel 11. The bottom wall of the air outlet channel 11 is provided with a blade groove 13. The wind sweeping assembly 20 is movably provided with respect to the bottom case 10. The wind sweeping assembly 20 has an operating position located in the wind outlet channel 11, and the wind sweeping assembly 20 has a hidden position located in the accommodating space 12. The shielding assembly 30 is movably disposed relative to the bottom case 10. The shutter member 30 has a closed position to shutter the vane groove 13, and the shutter member 30 has an escape position away from the vane groove 13. The number of the driving assemblies 40 is at least one. The driving assembly 40 is connected with the side wall of the air outlet channel 11, and the driving assembly 40 is respectively connected with the air sweeping assembly 20 and the shielding assembly 30. The driving assembly 40 can drive the wind sweeping assembly 20 to switch between the working position and the hiding position through the blade grooves 13, and the driving assembly 40 can drive the shielding assembly 30 to switch between the closing position and the avoiding position.

Use the technical scheme of the utility model, indoor set accessible drive assembly 40 drive sweep wind subassembly 20 in operating position with hide and switch between the position for the indoor set can change the wind direction and use to sweep wind subassembly 20 in needs, will sweep wind subassembly 20 and hide when need not changing the wind direction, prevent to sweep wind subassembly 20 and lie in air-out passageway 11 all the time and influence the air-out speed and the amount of wind of indoor set, utilize drive assembly 40 drive simultaneously to shelter from subassembly 30 in the closed position with dodge to switch between the position for air-out passageway 11 and accommodation space 12 communicate selectively, shelter from subassembly 30 when being located the closed position, air-out passageway 11 cuts off with accommodation space 12, can effectively prevent revealing of air-out air current, reduce the condensation phenomenon in the indoor set. Adopt the technical scheme of this application, the subassembly of sweeping the wind of having solved the indoor set among the prior art effectively shelters from the problem that the air-out passageway influences air-out speed and amount of wind.

The air sweeping component 20 is freely hidden, and the shielding component 30 is designed to be matched with the indoor unit to enable the indoor unit to have two modes of pushing out and retracting the air sweeping component. When the user needs to use the function of left-right wind sweeping, the wind sweeping component 20 can be controlled to push out and adjust the wind direction. When the user does not need to use the air sweeping assembly 20, the air sweeping assembly is retracted into the air conditioner, so that the air outlet resistance is reduced, and the air volume is increased. In the existing indoor unit, the air sweeping component 20 is detachably arranged, and when a user needs to sweep air by the air sweeping component 20, the air sweeping component cannot be quickly installed. By adopting the technical scheme of the embodiment, the two modes do not need to depend on disassembly operation, and can be freely selected and controlled by a user. By improving the structures of the bottom shell 10, the air sweeping assembly 20 and the like, the structure of the indoor unit is relatively simple and reliable, two modes can be realized by utilizing at least one driving assembly 40, and the cost of the indoor unit is well controlled.

That is, as shown in fig. 22 and fig. 30, when the air sweeping component 20 enters any one of the air outlet channel 11 or the accommodating space 12, the shielding component 30 seals the blade groove 13, so as to effectively prevent the air flow exchange in the accommodating space 12 and the air outlet channel 11 from affecting the working effect of the indoor unit. As shown in fig. 26, when the shielding assembly 30 is far away from the blade groove 13, the wind sweeping assembly 20 can be switched between the working position and the hidden position through the blade groove 13.

As shown in fig. 4, the wind sweeping assembly 20 includes a rotating shaft 21 and a plurality of blades 22 spaced apart from the rotating shaft 21, and at least one end of the rotating shaft 21 is connected to the driving assembly 40.
