In the air conditioner of this embodiment, the air conditioner includes an air duct structure, and the air duct structure is the above-mentioned air duct structure.

The following explains the air conditioner of the present embodiment:

for the cabinet machine with reversible air outlet, when air is discharged in refrigeration, the volute tongue rotates to the lower side, so that the lower part of the air duct forms a dead end, partial space is wasted, and noise is easily caused. The air conditioner of this embodiment sets up a movable wind gap at the internal face in wind channel, can the inside air inlet region of effectual increase air conditioner, makes the air inlet more even simultaneously, reduces inside turbulent flow and causes the noise. And the increase of the air intake can increase the air outlet volume simultaneously, promote the complete machine performance, optimize user experience.

The wind gap switching mechanism 10 of this embodiment is at the during operation, and door plant part 2 slides down under baffle part 1's drive when the air conditioner air inlet, and the wind channel lateral wall has had an wind gap (supplementary wind gap 61) more for the air conditioner effectively utilizes the inside wind in wind channel, enlarges the air inlet region, avoids the regional too narrow of air inlet, and the whole forms a virtuous circle. Therefore, the air conditioner can ensure smooth air inlet, avoid the separation of the air duct curve and the air flow to generate vortex, reduce the strength of the vortex and reduce the noise of the vortex.

As shown in fig. 7, when the tuyere switching mechanism 10 blocks the auxiliary tuyere 61, the door member 2 is held in an open state by the stress of the spring (elastic member 3) of the shutter member 1. A certain travel space is reserved inside the air opening switching mechanism 10 and is reserved for closing the door panel part 2. Inclined surfaces (a first guide inclined surface 611 and a second guide inclined surface 23) are respectively provided on the mating surfaces of the door panel part 2 and the air duct to facilitate the up-and-down movement of the door panel part 2. Sponge or rubber is arranged on the matching surface of the air duct and the door panel component 2 to ensure the tightness.

When the air opening switching mechanism 10 starts to move, the door panel part 2 is also subjected to a downward driving force, and the force is transmitted to the inclined surface of the air duct. Door plant part 2 uses pivot structure 21 to rotate as the rotation axis, and door plant part 2 front end moves up to baffle part 1 inboard, and the spring extrusion atress simultaneously lets door plant part 2 wholly be located the wind channel surface, guarantees that wind gap switching mechanism 10 can wholly move along the guide rail on the wind channel surface.

When the air conditioner needs to discharge air, the integrity of the inner wall of the air duct needs to be ensured, and the air opening switching mechanism 10 needs to be closed at the moment. At this time, the motor rotates reversely to drive the tuyere switching mechanism 10 to move upward. When the flap member is moved to the limit position, the spring pushes the door panel member 2 back to the original position due to the release stress. The door plate part 2 can be jointed with the inner wall of the air duct when closed, so that wind energy is ensured to be tightly attached to the air duct, and the eddy noise formed by steps is reduced.

With the arrangement, when the air duct structure needs air inlet, the baffle plate part 1 drives the door plate part 2 to move and reach the position avoiding the auxiliary air opening 61, so that air flow in the air duct structure can smoothly flow from the auxiliary air opening 61, and the air inlet capacity of the air duct structure is enhanced by the auxiliary air opening 61. When the auxiliary air port 61 of the air duct structure needs to block air flow, the baffle plate part 1 drives the door plate part 2 to move, the position for blocking the auxiliary air port 61 is reached, at the moment, the door plate part 2 moves relative to the baffle plate part 1, so that the door plate part 2 blocks the auxiliary air port 61 at the best position, the best blocking effect is reached, and when the air duct structure does not need the auxiliary air port 61 to ventilate, the wind blocking performance of the auxiliary air port 61 can be ensured.
