In the present embodiment, the air guide 20 has a three-dimensional structure as a whole, and is not plate-shaped. As can be understood by those skilled in the art, the arrangement of the first air deflector 21 reduces the air passing area, resulting in large air outlet resistance and small air volume. For this reason, the end plates 24 are respectively arranged at the two ends of the air guide 20 in the direction of the rotating shaft 25, on one hand, the air passing area is increased by arranging the air dispersing structure 210 on the end plates 24, and on the other hand, the end plates 24 also play a role in strengthening the connection between the first air guide plate 21 and the second air guide plate 40, so that the whole structure of the air guide 20 is more firm and durable.

In an embodiment, referring to fig. 1 and fig. 3, the first air outlet 12 is long, the rotating shaft 25 of the air guiding component 20 extends along the length direction of the first air outlet 12, and the air guiding inlet 23, the first air guiding plate 21 and the air blocking plate 22 respectively extend along the length direction of the first air outlet 12. In this embodiment, the air guide 20 is in a cylindrical shape, and the shape of the air guide is adapted to the first air outlet 12, and the first air guide plate 21 and the air blocking plate 22 sequentially rotate to a proper position along the rotating shaft 25 by the rotation of the air guide 20 along the rotating shaft 25, so as to achieve the purpose of discharging air without wind sense or completely closing the first air outlet 12. Specifically, the air guide 20 may be provided in a cylindrical shape or other tubular shape. So, just can realize the switching to 12 multiple states of first air outlet through simple rotation connection structure, overall structure is simple, low in production cost.

The position where the rotating shaft 25 is provided may be set as desired. For example, the entire air guide 20 may be cylindrical, the rotation shaft 25 may be provided at the center axis of the air guide 20, and the air guide 20 may rotate to switch between the open position and the closed position. But this arrangement does not fully open the first outlet mouth 12. In the present embodiment, referring to fig. 5, the rotating shaft 25 is located at a side of the wind shielding plate 22 adjacent to the wind guiding inlet 23. Thus, the first air outlet 12 can be completely opened, and normal air supply is realized.

In an embodiment, referring to fig. 1 and 3, the first air outlet 12 extends along a horizontal direction, and the rotating shaft 25 is located at a lower end of the air guiding element 20. It is understood that, in the present embodiment, the first air outlet 12 is not necessarily completely parallel to the horizontal direction, but extends along the horizontal direction, the rotating shaft 25 is located at the lower end of the air guide 20, so that when the air guide 20 is located at the open position, the wind deflector 22 is inclined upwards at the outer side of the first air outlet 12, and the wind deflector 22 and the first air deflector 20 together cover the first air outlet 12. In this way, the wind deflector 22 also functions as a deflector when the wind deflector 20 is in the open position, so that the airflow is restricted by the wind deflector 22 to flow upward and blow toward the ceiling. When the air conditioner is used for refrigerating, the cold air does not directly blow to the human body, but flows upwards, is blown to the indoor and then sinks under the action of gravity, the distribution characteristic of the air is met, the refrigerating effect is good, and a user feels comfortable.

Specifically, referring to fig. 5, the cross section of the air guide member 20 is in a fan shape with one side open so as to have an open side, a linear side and an arc side, the air inlet 23 forms the open side, the wind shield 22 forms the linear side, and the first air guide plate 21 is arranged in an arc shape so as to form the arc side. In this way, the shape of the air guide 20 conforms to the rotation path, so that the air guide 20 rotates more smoothly and is less likely to interfere with the casing 10 around the first air inlet 23. On the other hand, the first air deflector 21 arranged in the arc surface has a larger area than the linear air deflector, so that more areas can be provided with the air dispersing structures 210 to increase the air passing area and increase the output. Moreover, the air guide 20 has a regular overall structure, an attractive and smooth appearance and is easy to clean.

In an embodiment, referring to fig. 1 to 4, the housing 10 is provided with a second air outlet 13 spaced apart from the first air outlet 12, and the second air outlet 13 is communicated with the air outlet duct 11. In this embodiment, through addding the air outlet, realize two way air-outs in the indoor set 100 of air conditioning, further increase air output, so, partly offset because set up the micropore and realize not having the wind sense air-out, lead to the air output to reduce and the adverse effect that brings.

Thus, the first outlet 12 can realize no-wind-sensing air outlet, and the second outlet 13 can realize no-wind-sensing air outlet and normal air outlet. In the normal air-out state, the air guide 20 rotates to the closed position to block the first air outlet 12, and the second air outlet 13 discharges air normally. In the no-wind-sensing air-out state, the air guide 20 rotates to the open position, the first air outlet 12 outputs no wind-sensing air, and the air flow blows upwards, and the second air outlet 13 can output normal air or output no wind-sensing air. Preferably, a second air deflector 40 is installed at the second air outlet 13, and the second air deflector 40 has an air dispersing structure 210. So, second air outlet 13 can not have the wind and feel the air-out, realizes that first air outlet 12 and second air outlet 13 do not have the wind jointly and feels the air-out to the setting of two way air-outs, the increase air output reduces because there is not wind to feel the air-out and leads to the amount of wind to reduce and the not good adverse effect of heat transfer effect.

Further, referring to fig. 2 and 4, a ventilation channel 30 is disposed between the first air outlet 12 and the second air outlet 13, the first air outlet 12 is communicated with the air outlet duct 11 through the ventilation channel 30, a valve 31 is disposed at the ventilation channel 30, and the valve 31 is movably mounted on the housing 10 to open or close the ventilation channel 30. It can be understood that, in the normal air-out state, the air guide 20 rotates to the closed position to close the first air outlet 12, and the air in the air-out duct 11 is all blown into the room from the second air outlet 13. At this time, if there is a branch without an outlet in the air outlet duct 11, the airflow is gathered, the wind resistance is large, and noise is easily generated. Therefore, the valve 31 is arranged to block the airflow from flowing to the first air outlet 12, so that the inner shape of the air outlet duct 11 is more regular, the air outlet is smoother, and the noise is reduced.
