In the present embodiment, the first and second flyer blade assemblies 300 and 400 extend in the vertical direction to the same length. The horizontal swing blade assembly 500 is disposed at the inner sides of the first vertical swing blade assembly 300 and the second vertical swing blade assembly 400, and is used for adjusting the vertical air outlet direction of the air outlet 113.
As shown in fig. 4 and 5, the yaw blade assembly 500 includes: a vertical link 510, a plurality of yaw vanes 520, and a first motor 530. The vertical connecting rod 510 extends vertically along the air conditioner; the plurality of horizontal swing blades 520 are arranged along the vertical direction of the air conditioner at intervals, and the root of each horizontal swing blade 520 is provided with a rotating shaft connected with the vertical connecting rod 510. The output end of the first motor 530 is connected to one end of the vertical link 510, and is used for driving the vertical link 510 to move up and down, so as to drive the plurality of horizontal swinging blades 520 to swing.

As shown in fig. 6, the first vertical swing blade assembly 300 includes: a first air-out frame 310, a plurality of first vertical swinging blades 320 and a second motor 330. The first air-out frame 310 is a rectangular frame located on the plane of the air outlet 113, and is used for connecting a plurality of first vertical swing blades 320. The center of the top of the first air-out frame 310 is provided with a rotating shaft for connecting the second motor 330. The plurality of first vertical swing blades 320 are arranged in the area defined by the first air outlet frame 310 at intervals along the transverse direction of the air conditioner, and two ends of each first vertical swing blade 320 are connected with the first air outlet frame 310. The output end of the second motor 330 is connected to the rotating shaft at the top of the first air-out frame 310, and is used for driving the first air-out frame 310 to rotate around a vertical straight line (i.e. the straight line where the rotating shaft is located) so as to drive the plurality of first vertical swing blades 320 to move. When the first air-out frame 310 is located at the initial position (i.e. when the first air-out frame 310 does not rotate at any angle), each of the first vertical swing blades 320 is perpendicular to the plane of the air outlet 113, and at this time, the air outlet 113 supplies air to the front. When the first air-out frame 310 rotates, the angles of the plurality of first vertical swinging blades 320 change accordingly, for example: when the first air-out frame 310 rotates leftwards, the included angle between the plurality of first vertical swing blades 320 and the plane where the air outlet 113 is located changes, and at this time, the air outlet 113 supplies air to the left side. When the first air-out frame 310 rotates rightwards, the air outlet 113 blows air to the right side.
The second vertical swing blade assembly 400 includes: a second air-out frame 410, a plurality of second vertical swinging blades 420 and a third motor 430. A plurality of second vertical swing blades 420 are arranged in the region defined by the second air outlet frame 410 at intervals along the transverse direction of the air conditioner, and two ends of each second vertical swing blade 420 are connected with the second air outlet frame 410. And an output end of the third motor 430 is connected to the second air-out frame 410, and is configured to drive the second air-out frame 410 to rotate around a vertical straight line, so as to drive the plurality of second vertical swing vanes 420 to move. The structure of the second vertical swing blade assembly 400 is similar to the structure of the first vertical swing blade assembly 300, and thus, the detailed description thereof is omitted. Different from the above, the third motor 430 is disposed below the second air-out frame 410, and a rotating shaft for connecting the third motor 430 is disposed at the center of the bottom of the second air-out frame 410. In this embodiment, the first and second vertical swing blades 320 and 420 can swing within an angle range of 34 ° from left to right to realize left air outlet or right air outlet of the air conditioner.
In this embodiment, preferably, the first air-out frame 310 and the second air-out frame 410 are connected through a rotating shaft. That is, the first air-out frame 310 and the second air-out frame 410 can rotate relatively. By the arrangement, the two vertical swing blade assemblies are more compact in structure, the space utilization rate of the air outlet 113 of the air conditioner is improved, and the rotation stability of the two vertical swing blade assemblies is improved.
As shown in fig. 7, the air conditioner further includes: a volute 600 and an air outlet duct 700. The scroll 600 is disposed inside the casing 100 at an outer side of the crossflow blower 200 for guiding an air flow running direction of the crossflow blower 200. The volute 600 has an inlet and an outlet, the inlet of the volute 600 faces the air inlet 116 of the housing 100, and the outlet of the volute 600 faces the air outlet 113 of the housing 100. The air outlet duct 700 is connected to the outlet of the volute 600 and the air outlet 113 of the housing 100, and a flange 710 extending vertically along the air conditioner is disposed on the inner side of the air outlet duct wall 701 of the air outlet duct 700 close to the air outlet 113.
As shown in fig. 8, the flange 710 is formed by a first arc-shaped surface 711 and a second mutual surface rising from the inner side of the air passage wall 701. In the present embodiment, the cambered surface curvature radius R1 of the inner side of the air duct wall 701, the curvature radius R2 of the first arc-shaped surface 711, and the curvature radius R3 of the second arc-shaped surface 712 satisfy the following constraint conditions: r1 is more than 95mm and less than 105 mm; r2 is more than 2mm and less than 4 mm; 18mm < R3 < 22 mm. And R1, R2 and R3 satisfy the following relationships: 4 × (R2+ R3) < R1.
Through a plurality of tests of the inventor, the rotating speed of the cross-flow fan 200 is in the range of 600r/min to 1000r/min, and when the shape of the flange 710 meets the conditions, the coanda effect can be generated. The Coanda Effect (Coanda Effect), also known as Coanda Effect or Coanda Effect, refers to the tendency of a fluid (water or gas stream) to flow along a convex object surface instead of moving away from the original direction of flow. When there is surface friction (also called fluid viscosity) between the fluid and the surface of the object over which it flows, the fluid follows the surface of the object as long as the curvature is not large. Therefore, the flange 710 at the air outlet 113 can change the flow direction of the outlet airflow, that is, the outlet airflow flows along the flange 710 and is not directly blown onto the air conditioner decorative plate, thereby effectively avoiding the problem of condensation on the air conditioner decorative plate.
In fig. 9, the second vertical swing blade assembly 400 swings to have the air outlet direction facing the left side of the air conditioner, and for the user facing the air conditioner, the air outlet direction is facing the right side of the user. When the user is at the left side of the air conditioner, the user can enjoy a sense of no wind. In fig. 10, the second vertical swing blade assembly 400 swings to have the air outlet direction facing the right side of the air conditioner, and for the user facing the air conditioner, the air outlet direction is towards the left side of the user. When the user is at the right side of the air conditioner, the user can enjoy a sense of no wind. The air outlet directions of the first vertical oscillating blade assembly 300 in fig. 9 and 10 are both right ahead.
As shown in fig. 11, the air supply control device 800 of the air conditioner of the present embodiment includes: a detection module 801, a judgment module 802 and a driving module 803. Wherein, the detection module 801 can be configured to detect the preset range in front of the air conditioner by using the infrared sensor 117 disposed at the front of the housing. The determination module 802 may be configured to determine whether a user is present within a preset range according to the detection result of the infrared sensor 117. The driving module 803 may be configured to drive the yaw blade assembly 500 and the second yaw blade assembly 400 to act when a user is present within a preset range.
The preset range is a preset distance in front of the air conditioner, the air conditioner is in a region with a preset angle in transverse left and right radian, and the preset range comprises a first range on the left side in front of the air conditioner and a second range on the right side in front of the air conditioner. In a preferred embodiment, the predetermined distance is 1.5 meters and the predetermined angle is 70 °. That is, the preset range is an area which is 1.5 meters in front of the air conditioner and has 70 degrees of transverse left and right radian of the air conditioner. The area with 70 degrees of transverse left-right radian of the air conditioner refers to the total area of 35 degrees of transverse middle of the air conditioner to the left and 35 degrees of transverse middle of the air conditioner to the right. It should be noted that the specific values of the preset distance and the preset angle are only examples, and in other embodiments, the specific values may also be set according to actual situations. Since both the first and second flaps 320 and 420 swing within a limited range in the left-right direction, the detection area of the infrared sensor 117 does not have to be the entire open area in front of the air conditioner.

Since the yaw blade assembly 500 and the second yaw blade assembly 400 can blow directly to the user, the air supply control methods of the air conditioner control the air outlet directions of the yaw blade assembly 500 and the second yaw blade assembly 400 under different conditions. In addition, the air-out direction of first vertical pendulum blade subassembly 300 can also confirm through the input operation who acquires the user to can drive first vertical pendulum blade subassembly 300 and swing to the air-out direction that its air-out direction orientation confirmed.
