And then the second air deflector 4 and the third air deflector 5 are synchronously controlled to keep a corresponding superposition state or a staggered state to synchronously rotate.
As shown in fig. 9, when cooling and blowing are performed, the first air guiding plate 3 is located at the first rotation axis O1Near one side of the air outlet duct 11 (located at the first rotation axis O)1The rear side) and is close to the upper frame of the air-out frame 14; the inner arc surface of the first air deflector 3 is positioned at the upper side of the outer arc surface. The second air guiding plate 4 and the third air guiding plate 5And the inner arc surfaces of the second air guide plate 4 and the third air guide plate 5 are positioned at the upper side of the outer arc surfaces thereof in a superposed state.
In addition, the curvature of the first air deflector 3 is greater than that of the second air deflector 4, and the first air deflector 3, the second air deflector 4 and the third air deflector 5 jointly define a tapered air flow channel 10 along the air flow direction; the air flow channel 10 of the gradual shrinkage type extrudes air flow to enable the air flow to have higher air outlet kinetic energy, the air outlet speed is effectively improved, the air supply distance is increased, cold air keeps a longer distance at the upper part of a room, and the influence of falling wind on use feeling is prevented.
At right angles to the first axis of rotation O1The projections of the first air guiding plate 3, the second air guiding plate 4 and the third air guiding plate 5 in the plane are downward convex. When cold air blows out and flows through the airflow channel 10, the cold air is firstly blocked by the lower second air guide plate 4 and the lower third air guide plate 5 integrally, the trend of blowing air downwards is blocked, but due to the fact that the density of the cold air is large, the cold air sinks after being blown out for a certain distance, and people are blown out. In addition, the curvature of the first air deflector 3 is large, the air flow is influenced by the large-curvature air guide when passing through the lower surface (extrados) of the first air deflector 3, an upward inclined angle is increased during air outlet, and the blown air flow has larger upward momentum, so that the blown air flow can be ensured to have a farther horizontal distance without falling to the ground, and the refrigerating comfort is improved.
As shown in fig. 10, when the air is supplied by the cooling soft wind, the first wind deflector 3 is located at the first rotation axis O1The upper frame is close to one side of the air outlet duct 11 and close to the air outlet frame 14; the inner arc surface of the first air deflector 3 is positioned at the upper side of the outer arc surface.

Under the condition of refrigeration and soft wind supply, after the second air deflector 4 and the third air deflector 5 are adjusted to be in a staggered state, the second motor 8 and the third motor 9 synchronously rotate, so that the second air deflector 4 and the third air deflector 5 keep in a staggered state and synchronously rotate to disturb air flow, and therefore, the air flow is disturbedSo that the airflow fluctuates periodically to generate a soft wind effect.
As shown in fig. 11, when heating and blowing, the first air guiding plate 3 rotates around the first rotation axis O1Rotate to a first rotation axis O1The side far away from the air outlet duct 11; the inner arc surface of the first air deflector 3 is positioned at the lower side of the outer arc surface thereof.

I.e. perpendicular to the first axis of rotation O1In the plane projection of (a), the projections of the first air guiding plate 3, the second air guiding plate 4 and the third air guiding plate 5 are convex upward. In the above, the second air deflector 4 and the third air deflector 5 are in a superposed state to form a whole; and forms an air flow channel 10 extending downwards with the first air deflector 3, so that the hot air flows downwards, and the hot air is separated from the air deflector and flows towards the ground, so as to blow the hot air downwards, ensure that the hot air can blow to the ground, and spread to the whole room from the ground, and realize carpet type heating and air supply.
As shown in fig. 12, when heating and blowing are performed; the first air deflector 3 is positioned on the first rotating shaft O1Far away from one side of the air outlet duct 11, and the inner arc surface is located at the lower side of the outer arc surface, so that the hot air flows downwards. That is, the first air guide plate 3 remains stationary with respect to the heating air supply.
The second air deflector 4 rotates 90 degrees relative to the third air deflector 5, namely, the angle A1O2A2The second air guiding plate 4 and the third air guiding plate 5 are in a staggered state when the angle is equal to 90 degrees. Under the condition of heating and soft wind blowing, after the second air deflector 4 and the third air deflector 5 are adjusted to be in a staggered state, the second motor 8 and the third motor 9 synchronously rotate, so that the second air deflector 4 and the third air deflector 5 are kept in the staggered state to rotate, and the air flow is disturbed, so that the air flow periodically fluctuates, and a soft wind effect is generated.
When the air is supplied by the refrigerating soft wind or the heating soft wind, the second air deflector 4 and the third air deflector 5 are in a staggered state and keep rotating all the time in the staggered state, so that the air flow is disturbed to generate a soft wind effect. It should be noted that the generation of the soft wind effect is not limited to the above way of forming the interlaced state first and then keeping the interlaced state to rotate; the second air guiding plate 4 and the third air guiding plate 5 can rotate asynchronously to form a dynamic interleaving effect through the rotation speed control of the second motor 8 and the third motor 9, so as to generate a soft wind effect.
In this embodiment, the first air guiding plate 3, the second air guiding plate 4 and the third air guiding plate 5 which are staggered with each other cooperate together to guide the flow, so that the temperature adjusting effect is improved, the air flow of the cross section of the whole air outlet duct can be disturbed, the air flow disturbance range is enlarged, and the soft air effect is effectively enhanced.
In addition, the air conditioning indoor unit is not limited to an indoor unit, and may be a ceiling unit installed in a manner of being embedded in an indoor ceiling.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
