[0032] The wind sweeping blade assembly 80 of the present invention is suitable for an air conditioner, the air outlet device of the air conditioner includes an air outlet channel 30 and a first air guide plate 10 movably arranged at the air outlet 40 of the air outlet channel 30, the first air guide plate 10 having a first closing position closing at least part of the air outlet 40 and a first opening position opening at least part of the air outlet 40; the wind sweeping blade assembly 80 includes: a connecting rod 1 movably arranged in the air outlet channel 30 and located on the bottom shell 50 of the air conditioner; a plurality of wind sweeping blades 2 movably arranged on the connecting rod 1 and arranged at intervals along the connecting rod 1; wherein the wind sweeping blades 2 include a avoidance position accommodated at a side of the air outlet channel 30 close to the connecting rod 1 to avoid airflow and a wind guiding position unfolded in the air outlet channel 30 to guide airflow; the wind sweeping blades 2 are switchably arranged between the avoidance position and the wind guiding position to switch synchronously with the switching between the first closing position and the first opening position of the first air guide plate 10. In this way, the present invention provides a sweeping blade assembly 80 with a storage and hiding function. Only when the air conditioner is in a heating state will the sweeping blade 2 be unfolded and move with the connecting rod 1 to sweep the air left and right, so as to improve the user's comfort experience. When the air conditioner is in other states, the sweeping blade 2 is stored and hidden, which solves the problem in the prior art that the small air guide plate of the air conditioner will rotate toward the inside of the air conditioner during heating, thereby causing the conventional sweeping blade to be unable to work normally.

[0033] like Figure 2 and Figure 3As shown, the wind sweeping blade 2 includes: a shaft body 21, a first end of the shaft body 21 is connected to the bottom shell 50 of the air conditioner, and a second end of the shaft body 21 is connected to the connecting rod 1 to move with the connecting rod 1; a blade portion 22, a first side of the blade portion 22 is connected to the shaft body 21, and a second side of the blade portion 22 is connected to the free side of the first air guide plate 10, so as to drive the wind sweeping blade 2 to switch between the avoidance position and the air guiding position through the movement of the first air guide plate 10.

[0034] Preferably, the shaft body 21 and the connecting rod 1 are disposed on and inside the bottom shell 50 , so that the blade portion 22 of each wind sweeping blade 2 can be hidden in the bottom shell 50 without interfering with the upward air outlet.

[0035] like Figure 3 and Figure 4 As shown, the connection point 5 between the second end of the shaft body 21 of each wind sweeping blade 2 and the connecting rod 1 moves driven by the connecting rod 1 to drive the corresponding wind sweeping blade 2 to swing left and right around the rotation axis 4 within a certain angle range to sweep the wind left and right.

[0036] Optionally, the blade portion 22 is a flexible member, which can be stored in the avoidance position by being rolled or folded.

[0037] Specifically, the blade portion 22 is made of a flexible material, such as high-density cloth or flexible plastic.

[0038] The wind sweeping blade assembly 80 of the present invention also includes a wind sweeping driving unit, which is arranged on the bottom shell 50 of the air conditioner and is drivingly connected to the connecting rod 1 to drive the connecting rod 1 to drive the second end of the shaft body 21 of each wind sweeping blade 2 to move to achieve left and right wind sweeping.

[0039] Preferably, the fixed side of the first air guide plate 10 is connected to the main body of the air conditioner via a rotating shaft, and the second side of the blade portion 22 is connected to the free side of the first air guide plate 10, so that the second side of the blade portion 22 can be driven to move by the movement of the free side of the first air guide plate 10, thereby expanding or retracting the blade portion 2.

[0040] like Figure 5 As shown, when the first air guide plate 10 is located at the first closed position, the free side of the first air guide plate 10 is located on the side of the air outlet 40 close to the shaft portion 21 of each wind sweeping blade 2, so that the second side of the blade portion 22 of each wind sweeping blade 2 is located on the side of the air outlet channel 30 close to the shaft portion 21, that is, the blade portion 22 is in a retracted state.

[0041] like Figure 6As shown, when the first air guide plate 10 is located at the first open position, the free side of the first air guide plate 10 is located in the air outlet channel 30 and on the side of the air outlet channel 30 away from the shaft portion 21 of each wind sweeping blade 2, so that the second side of the blade portion 22 of each wind sweeping blade 2 is located on the side of the air outlet channel 30 away from the shaft portion 21, that is, the blade portion 22 is in an unfolded state.

[0042] like Figure 1 As shown, the second side of the blade portion 22 is connected to the free side of the first air guide plate 10 via a rope body 3 .

[0043] The air conditioner of the present invention further comprises: a first driving unit 11 , which is drivingly connected to the first air guide plate 10 to drive the first air guide plate 10 to move.

[0044] like Figure 1 As shown, the first driving unit 11 includes a first motor 111, a gear box 112 and a crankshaft 113. The first motor 111, the gear box 112, the crankshaft 113 and the first air guide plate 10 are connected in sequence so that the first motor 111 drives the first air guide plate 10 to move through the gear box 112 and the crankshaft 113.

[0045] The present invention provides an air outlet device, which is suitable for an air conditioner. The air outlet device includes an air outlet channel 30 and a first air guide plate 10 movably arranged at an air outlet 40 of the air outlet channel 30. The first air guide plate 10 has a first closed position that closes at least part of the air outlet 40 and a first open position that opens at least part of the air outlet 40. The air outlet device also includes the above-mentioned wind sweeping blade assembly 80, which is arranged in the air outlet channel 30.

[0046] like Figure 1 , Figures 3 to 6 As shown, the air outlet device includes: a second air guide plate 20, which is movably arranged at the air outlet 40, and the second air guide plate 20 has a second closed position for closing at least part of the air outlet 40 and a second open position for opening at least part of the air outlet 40.

[0047] Among them, one of the first closed position and the first open position of the first air guide plate 10 is combined with one of the second closed position and the second open position of the second air guide plate 20 to jointly open or close the air outlet 40 or form different air outlet modes.

[0048] Specifically, the air conditioner is a wall-mounted air conditioner, at least a portion of the second air guide plate 20 is located on a side of the first air guide plate 10 away from a supporting base (such as the ground), the first air guide plate 10 is located on a side of the air outlet 40 close to the supporting base (such as the ground) for downward air outlet, and the second air guide plate 20 is located on a side of the air outlet 40 away from an installation base (such as a wall) of the air conditioner for upward air outlet; and / or an air guide area of ​​the second air guide plate 20 is greater than an air guide area of ​​the first air guide plate 10.

[0049] like Figure 1 As shown, the first air guide plate 10 is located at the first closed position, the second air guide plate 20 is located at the second closed position, the wind sweeping blade 2 is located at the avoidance position, and the rope body 3 is in a taut state. At this time, the air outlet 40 is completely closed, the air outlet device is in a closed state, and the air conditioner is in a turned-off state. At the same time, the gear box 112 ensures through its own locking force that even if the air conditioner is powered off, the wind sweeping blade 2 will not be unfolded, causing the small air guide plate to be unable to close.

[0050] like Figure 5 As shown, the first motor 111 drives the gear in the gear box 112 to rotate, so as to drive the crankshaft 113 to rotate, thereby driving the first air guide plate 10 to rotate from the first closed position to the first open position, and the free side of the first air guide plate 10 drives the second side of the sweeping blade 2 to move through the rope body 3, so that the sweeping blade 2 moves from the avoidance position to the wind guiding position, while the second air guide plate 20 remains in the second closed position unchanged. At this time, the part of the air outlet 40 close to the bottom is opened, the air outlet device is in the lower air outlet state, the air conditioner is in the heating state, and each sweeping blade 2 sweeps the air left and right under the drive of the connecting rod 1. At the same time, the gear box 112 ensures that the sweeping blade 2 will not roll back when the first air guide plate 10 is opened through its own locking force.

[0051] When the air conditioner starts to shut down in the heating state, the connecting rod 1 is reset to drive each wind sweeping blade 2 to reset, and at the same time the self-locking of the gear box 112 is released and driven by the first motor 111 to drive the first air guide plate 10 to rotate outward to close the air outlet 40, and the wind sweeping blade 2 is retracted to the avoidance position by its own curling force.

[0052] like Figure 6 As shown, the first air guide plate 10 is located in the first closed position, the second air guide plate 20 is located in the second open position, and the wind sweeping blade 2 is located in the avoidance position. At this time, the upper part of the air outlet 40 is opened, the air outlet device is in the upper air outlet state, and the air conditioner is in the cooling state. The second air guide plate 20 is opened alone to realize the cooling upper air outlet to avoid the cold wind blowing directly on people. Since the cold wind will not blow directly on people, there is no need to sweep the air left and right. The first air guide plate 10 is closed and motionless, and the wind sweeping blade 2 is stored and hidden on the side close to the shaft body 21 and does not participate in the work.

[0053] The present invention further provides an air conditioner, comprising the above-mentioned air outlet device. The air conditioner of the present invention is a wall mounted air conditioner, comprising a housing 90, a fan 60 and a heat exchanger 70 disposed in the housing 90, and an air outlet channel 30 of the air outlet device connects the air outlet of the fan 60 with the air outlet 40 of the air conditioner.

[0054] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0055] The wind sweeping blade assembly 80 of the present invention is suitable for an air conditioner, the air outlet device of the air conditioner includes an air outlet channel 30 and a first air guide plate 10 movably arranged at the air outlet 40 of the air outlet channel 30, the first air guide plate 10 having a first closing position closing at least part of the air outlet 40 and a first opening position opening at least part of the air outlet 40; the wind sweeping blade assembly 80 includes: a connecting rod 1 movably arranged in the air outlet channel 30 and located on the bottom shell 50 of the air conditioner; a plurality of wind sweeping blades 2 movably arranged on the connecting rod 1 and arranged at intervals along the connecting rod 1; wherein the wind sweeping blades 2 include a avoidance position accommodated at a side of the air outlet channel 30 close to the connecting rod 1 to avoid airflow and a wind guiding position unfolded in the air outlet channel 30 to guide airflow; the wind sweeping blades 2 are switchably arranged between the avoidance position and the wind guiding position to switch synchronously with the switching between the first closing position and the first opening position of the first air guide plate 10. In this way, the present invention provides a sweeping blade assembly 80 with a storage and hiding function. Only when the air conditioner is in a heating state will the sweeping blade 2 be unfolded and move with the connecting rod 1 to sweep the air left and right, so as to improve the user's comfort experience. When the air conditioner is in other states, the sweeping blade 2 is stored and hidden, which solves the problem in the prior art that the small air guide plate of the air conditioner will rotate toward the inside of the air conditioner during heating, thereby causing the conventional sweeping blade to be unable to work normally.
