Thus, through the arrangement of the first flow guide plate 421, smooth air outlet can be ensured when the air conditioner side discharges air.

Alternatively, as shown in connection with fig. 5, first deflector 421 has a vertical height greater than the travel of air deflector 411. Wherein, the vertical height of first air deflector 421 refers to the dimension of first air deflector 421 in the Z-axis direction in fig. 5, and the movement stroke of air deflector 411 refers to the lifting stroke of air deflector 411, and is also the vertical distance when air deflector 411 rises from the lowest position (i.e. the position when the lower end of air deflector 411 contacts with housing 1) to the highest position (i.e. the position when air deflector 411 is restricted by structure and can not rise any more); so to guarantee that deep bead 411 can contact with first guide plate 421 all the time at the lift in-process, prevent that deep bead 411 from breaking away from and producing the skew or rocking behind first guide plate 421, thereby guarantee deep bead 411's stable lift.

Optionally, as shown in fig. 3 to 5, the flow guiding assembly 42 further includes a second flow guiding plate 422 connected to the first flow guiding plate 421; one end of the second flow guiding plate 422 is connected to one end of the first flow guiding plate 421 away from the casing 1, and the other end extends towards the first air outlet 11 and is connected to the casing 1; the second baffle 422 is adapted to guide the airflow flowing to the second baffle 422 to be blown out from the first air outlet 11.

In this embodiment, the first baffle 421 and the second baffle 422 are located at the air duct intersection between the first air outlet 11 and the side air outlet 12, and preferably, the first baffle 421 and the second baffle 422 are integrally formed. The second baffle 422 is adapted to guide the airflow flowing to the second baffle 422 to blow out from the first air outlet 11 when the air conditioner is in operation; thus, when the wind deflector 411 is located at the open position, in the air flow flowing to the flow guiding mechanism, a part of the air flow flows to the first flow deflector 421 and blows out from the side air outlet 12 along the side of the first flow deflector 421 facing the side air outlet 12, and the other part of the air flow flowing to the second flow deflector 422 flows to the first air outlet 11 along the second flow deflector 422 and blows out from the first air outlet 11, so as to avoid that the air flow directly collides with the inner wall of the housing 1 to generate loud noise; when air baffle 411 is located the closed position, the air current that flows to the guiding mechanism flows to first air outlet 11 and blows off from first air outlet 11 along air baffle 411 and second guide plate 422, and air baffle 411 and second guide plate 422 play the guide effect to the air current promptly, have avoided the direct and interior wall collision of casing 1 of air current to produce great noise.

Optionally, as shown in fig. 3, the air baffle 411 and the second air baffle 422 are both arc-shaped plate structures, and the side surfaces of the air baffle 411 and the second air baffle 422 on the side away from the side air outlet 12 are located on the same arc surface. In this embodiment, the side that deep bead 411 and second guide plate 422 deviate from side air outlet 12 one side is the indent cambered surface, and is located same indent cambered surface, so, when deep bead 411 is located the closed position, the air current can not receive protruding hindrance when flowing to second guide plate 422 from deep bead 411 to can smoothly blow out from first air outlet 11 through deep bead 411 and second guide plate 422 in proper order, reduced the air current noise effectively.

Alternatively, as shown in fig. 3, the first baffle 421 and the second baffle 422 form a V-shaped plate structure, and an opening of the V-shaped plate structure faces to an end of the housing 1 away from the mounting surface. Thus, when the side air outlet 12 is opened, the airflow flowing to the flow guide assembly 42 forms a split flow at the first flow guide plate 421 and the second flow guide plate 422, so that a part of the airflow is blown out from the side air outlet 12 through the first flow guide plate 421, and the other part of the airflow is blown out from the first air outlet 11 through the second flow guide plate 422; and when the first guide plate 421 and the second guide plate 422 form a V-shaped plate structure, the whole guide assembly 42 is in a triangular structure, so that the structure is more stable.

Further, as shown in fig. 2, the side air outlet 12 includes a second air outlet 121 and a third air outlet 122 respectively disposed at two ends of the housing 1 in the length direction.

In this embodiment, the left end and the right end of the air conditioner are respectively provided with a second air outlet 121 (also the left air outlet of the housing 1) and a third air outlet 122 (also the right air outlet of the housing 1). The first bending section 21, the second bending section 22 and the third bending section 23 of the U-shaped heat exchanger 2 correspond to the second air outlet 121, the first air outlet 11 and the third air outlet 122 respectively, so as to ensure that wind energy after heat exchange of the first bending section 21 can be smoothly blown out from the second air outlet 121, wind energy after heat exchange of the second bending section 22 can be smoothly blown out from the first air outlet 11, and wind energy after heat exchange of the third bending section 23 can be smoothly blown out from the third air outlet 122.

Further, the air duct branch point between the second air outlet 121 and the first air outlet 11, and the air duct branch point between the third air outlet 122 and the first air outlet 11 are both provided with the flow guiding mechanism 4. For convenience of description, the air guiding mechanisms 4 respectively disposed at the two air switch ports are respectively referred to as a left air guiding mechanism and a right air guiding mechanism, the left air guiding mechanism controls the second air outlet 121 to be opened or closed, and the right air guiding mechanism controls the third air outlet 122 to be opened or closed. The motors 412 of the left diversion mechanism and the right diversion mechanism can be arranged in parallel or in series, when the two motors 412 are arranged in series, the left diversion mechanism and the right diversion mechanism are synchronously controlled, and at the moment, the second air outlet 121 and the third air outlet 122 are simultaneously opened or closed; when the two motors 412 are arranged in parallel, the left air guide mechanism and the right air guide mechanism are independently controlled, and at this time, the second air outlet 121 and the third air outlet 122 can be opened or closed simultaneously, or one of the second air outlet 121 and the third air outlet 122 is opened while the other is closed.

Further, the air guiding mechanism includes a first air guiding structure, a second air guiding structure 51 and a third air guiding structure 52 respectively disposed at the first air outlet 11, the second air outlet 121 and the third air outlet 122.

Therefore, the first centrifugal fan blade 31 and the second centrifugal fan blade 32 can be independently controlled, when users at the air supply areas of the first centrifugal fan blade 31 and the second centrifugal fan blade 32 have different requirements for the air outlet speed, the users at different areas can select the rotating speed of the centrifugal fan blade at the corresponding area according to actual requirements to reduce or increase the air outlet speed and the air outlet quantity of the centrifugal fan blade, so that the air conditioner can adapt to the use requirements of the users at different areas. Meanwhile, the motors 412 of the two diversion mechanisms 4 at the left end and the right end of the air conditioner are preferably arranged in parallel in the embodiment, so that the multidirectional and wide-area air outlet of the air conditioner has the advantages of being selectable and controllable, a user can conveniently select to open or close one or two of the second air outlet 121 and the third air outlet 122 according to actual needs, the requirement of unidirectional air supply or multidirectional air supply is met, and the application range of the air conditioner is widened.
