[0029] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0030] The wind sweeping assembly 120 of the embodiment of the present disclosure is used for an air conditioner 100. The air conditioner 100 includes a housing 110. The housing 110 is provided with an air outlet 1110. The wind sweeping assembly 120 includes a plurality of wind sweeping blades 1. The plurality of wind sweeping blades 1 extend in the extension direction of the housing 110 (such as Figure 1The wind sweeping blade 1 is located in the air outlet 1110 and is rotatable relative to the housing 110. The rotation axis of the wind sweeping blade 1 is orthogonal to the extension direction of the housing 110 and the opening direction of the air outlet 1110 (as shown in FIG. Figure 2 The wind sweeping blade 1 is provided with a through hole 11 penetrating the wind sweeping blade 1 along its thickness direction, and an angle is formed between an extending direction of the through hole 11 and a thickness direction of the wind sweeping blade 1.

[0031] Specifically, Figure 1-Figure 5 As shown, the inner contour of the air outlet 1110 on the projection surface parallel to the up and down directions and the left and right directions is in the shape of a rectangle, the wind sweeping assembly 120 is arranged in the air outlet 1110, the left end or the right end of the wind sweeping blade 1 is rotatably connected to the shell 110, and the rotation axis of the wind sweeping blade 1 extends along the left and right directions. The air outlet 1110 can be opened and blocked by rotating the wind sweeping blade 1, and the air flow direction of the air outlet 1110 can be adjusted by adjusting the rotation angle of the wind sweeping blade 1 to achieve up and down wind sweeping.

[0032] When the sweeping blade 1 blocks the air outlet 1110, since the sweeping blade 1 is provided with a through hole 11 which penetrates the sweeping blade 1 along its thickness direction, and there is an angle between the extension direction of the through hole 11 and the thickness direction of the sweeping blade 1, that is, the through hole 11 on the sweeping blade 1 is an inclined hole, at least part of the outlet air flow can flow out from the through hole 11 on the sweeping blade 1, and the direction of the air flow flowing out of the through hole 11 can be adjusted by adjusting the angle of the sweeping blade 1, so that the component direction of the direction of the air flow flowing out of the inclined hole is the same as the extension direction of the sweeping blade 1, thereby reducing the air volume loss and improving the performance of the air conditioner 100.

[0033] It can be understood that in the related technology, a straight hole is set on the sweeping blade 1, and the extension direction of the straight hole is always perpendicular to the extension direction of the sweeping blade 1, so that when the sweeping blade 1 changes the direction of the outlet airflow, the main airflow of the outlet airflow flows along the extension direction of the sweeping blade 1, and the airflow flowing out of the straight hole always maintains a perpendicular relationship with the main airflow. The airflow flowing out of the straight hole collides with the main airflow and becomes turbulent, the air volume and wind pressure are greatly attenuated, and the air volume loss is large.

[0034] Compared with the method of setting a straight hole on the sweeping blade 1 in the related art, in this embodiment, an inclined hole is set on the sweeping blade 1, and the rotation angle of the sweeping blade 1 is adjusted to change the drainage direction of the inclined hole, so that the main airflow of the outlet airflow flows along the extension direction of the sweeping blade 1, and the component direction of the extension direction of the inclined hole is the same as the main airflow direction of the outlet airflow, thereby reducing the impact of the airflow flowing out of the inclined hole on the main airflow, reducing the air volume loss, and improving the efficiency of the air conditioner 100.

[0035] In some embodiments, the wind sweeping blade 1 has a first end 12 and a second end 13 arranged opposite to each other in the extension direction of the wind sweeping blade 1, the first end 12 of the wind sweeping blade 1 is located upstream of the second end 13 of the wind sweeping blade 1 in the airflow direction, the wind sweeping blade 1 has a first side surface 14 and a second side surface 15 arranged opposite to each other in the thickness direction of the wind sweeping blade 1, the first side surface 14 of the wind sweeping blade 1 is higher than the second side surface 15 of the wind sweeping blade 1, and the through hole 11 extends from the first side surface 14 toward the second side surface 15 and is inclined in the direction from the first end 12 of the wind sweeping blade 1 to the second end 13 of the wind sweeping blade 1.

[0036] Specifically, Figure 5-Figure 7 As shown, the first end 12 of the wind sweeping blade 1 is located on the rear side, the second end 13 of the wind sweeping blade 1 is located on the front side, and the first side surface 14 of the wind sweeping blade 1 is higher than the second side surface 15, so that any position on the first side surface 14 of the wind sweeping blade 1 is always located above the corresponding position of the position on the second side surface 15, and the through hole 11 passes through the second side surface 15 from the first side surface 14, and the extension direction of the through hole 11 is inclined toward the rear side toward the front side to form an inclined hole inclined from the first end 12 to the second end 13. In this embodiment, by limiting the inclination direction of the inclined hole, the component direction of the airflow direction flowing out of the inclined hole can be the same as the main airflow direction, thereby reducing the impact of the airflow flowing out of the inclined hole on the main airflow and reducing the air volume loss.

[0037] In some embodiments, the sweeping blade 1 has a first position, in which a plurality of sweeping blades 1 are arranged at intervals in the extension direction of the housing 110 , and a first end 12 of the sweeping blade 1 is higher than a second end 13 of the sweeping blade 1 .

[0038] Specifically, Figure 6 As shown, in the first position, multiple sweeping blades 1 are arranged at intervals so that the main airflow of the outlet airflow flows along the first end 12 of the sweeping blade 1 toward the second end 13, the first end 12 of the sweeping blade 1 is higher than the second end 13 of the sweeping blade 1, and the sweeping blade 1 is tilted upward so that the main airflow flows downward.

[0039] The extension direction of the through hole 11 is inclined along the first end 12 of the sweeping blade 1 toward the second end 13 of the sweeping blade 1. Since the main airflow flows downward, the direction of the airflow flowing out of the through hole 11 of the sweeping blade 1 flows downward along the extension direction of the through hole 11, so that the component direction of the airflow flowing out of the through hole 11 is the same as the main airflow direction of the outlet airflow, thereby reducing the impact of the airflow flowing out of the through hole 11 on the main airflow, reducing the air volume loss, and improving the efficiency of the air conditioner 100.

[0040] For example, when the air conditioner 100 is in the heating mode, the hot air flow out of the air outlet 1110 flows downward through the wind sweeping blade 1, and the hot air will rise, making the indoor temperature more uniform and the heating effect better. In this embodiment, by making the component direction of the air flow out of the through hole 11 in the heating mode the same as the main air flow direction of the air outlet, the loss of the hot air volume for heating is small, the landing performance of the hot air for heating is better, and the heating pressure air performance is improved.

[0041] In some embodiments, the wind sweeping blade 1 has a second position, and the wind sweeping blade 1 can be switched between the first position and the second position. In the second position, multiple wind sweeping blades 1 are arranged at intervals in the extension direction of the shell 110, and the second end 13 of the wind sweeping blade 1 is higher than the first end 12 of the wind sweeping blade 1.

[0042] Specifically, Figure 7 As shown, in the second position, the plurality of sweeping blades 1 are arranged at intervals so that the main airflow of the outlet airflow flows along the first end 12 to the second end 13 of the sweeping blade 1, the first end 12 of the sweeping blade 1 is lower than the second end 13 of the sweeping blade 1, and the sweeping blade 1 is tilted downward so that the main airflow flows upward. The extension direction of the through hole 11 is tilted along the first end 12 of the sweeping blade 1 to the second end 13 of the sweeping blade 1. Since the main airflow flows upward, the direction of the airflow flowing out of the through hole 11 flows upward along the extension direction of the through hole 11, so that the component direction of the airflow direction flowing out of the through hole 11 is opposite to the main airflow direction of the outlet airflow.

[0043] For example, when the air conditioner 100 is in the cooling mode, the cold air flow out of the air outlet 1110 flows upward through the sweeping blade 1, and the cold air forms convection with the hot air in the room, resulting in a better cooling effect. In this embodiment, in the cooling mode, the component direction of the air flow flowing out of the through hole 11 is made opposite to the main air flow direction of the air outlet, thereby extending the cooling air outlet distance and improving the guiding effect of the sweeping blade 1.

[0044] In some embodiments, the wind sweeping blade 1 has a third position, and the wind sweeping blade 1 can be switched between the first position and the third position and between the third position and the second position. In the third position, the first end 12 of one of the two adjacent wind sweeping blades 1 overlaps the second end 13 of the other wind sweeping blade 1.

[0045] Specifically, Figure 8 As shown, in the third position, the first end 12 of the upper sweeping blade 1 overlaps the second end 13 of the lower sweeping blade 1, and the lower sweeping blade 1 overlaps the upper sweeping blade 1, and the outlet air flow flows out from the through hole 11 on the sweeping blade 1 to achieve a soft wind effect.

[0046] Compared with the related art in which a gap is provided between two adjacent wind sweeping blades 1, in the soft wind mode, part of the airflow flows out from the through hole 11 on the wind sweeping blade 1, and the other part of the airflow flows out from the gap between the two adjacent wind sweeping blades 1, and the airflow distribution is uneven, which reduces the soft wind effect. In this embodiment, by overlapping the two adjacent wind sweeping blades 1, there is no gap between the two adjacent wind sweeping blades 1, so that the outlet airflow can only flow out along the extension direction of the through hole 11 on the wind sweeping blade 1, which reduces the airflow velocity and has a better soft wind effect.

[0047] For example, in the third position, the air conditioner 100 is in the soft wind mode, and the wind is swept up and down by adjusting the rotation angle of the wind sweeping blade 1, so that the wind sweeping blade 1 can rotate between the first position, the second position and the third position, thereby realizing the adjustment of heating, cooling and soft wind modes.

[0048] For example, in this embodiment, when the wind sweeping blades 1 are in the third position, adjacent wind sweeping blades 1 are overlapped. Compared with the setting form in the related art where gaps are left between adjacent wind sweeping blades 1, the size of the wind sweeping blades 1 in the extension direction of the wind sweeping blades 1 in this embodiment can be set larger, thereby further improving the wind sweeping effect.

[0049] In some embodiments, the dimension of the first end 12 of the sweeping blade 1 in the first direction gradually decreases from the second end 13 of the sweeping blade 1 toward the first end 12 of the sweeping blade 1, and the first direction is orthogonal to the extension direction of the shell 110 and the opening direction of the air outlet 1110.

[0050] Specifically, Figure 4 As shown, the first direction is the left-right direction. When the wind sweeping blade 1 is in the first position, the outer contour of the first end 12 on the projection surface parallel to the left-right direction and the front-back direction is a trapezoid. The trapezoidal setting can better guide the gas flow and improve the uniformity of the airflow.

[0051] In some embodiments, the angle is between 30°-80°.

[0052] Specifically, Figure 5 As shown, the included angle is set to α. In this embodiment, the included angle between the extending direction of the through hole 11 and the thickness direction of the wind sweeping blade 1 is limited to facilitate better guiding of the airflow.

[0053] For example, the included angle is set to α, and the value of α is 30°, 40°, 35°, 50°, 60°, 66°, 70°, and 80°.

[0054] In some embodiments, there are a plurality of through holes 11 , and the plurality of through holes 11 are arranged at intervals on the wind sweeping blade 1 .

[0055] Specifically, Figure 4As shown, in this embodiment, by providing a plurality of through holes 11, the air flow can flow out from the plurality of through holes 11 at the same time, thereby improving the smoothness of the air flow.

[0056] In some embodiments, the wind sweeping assembly 120 also includes a driving assembly 2, the driving assembly 2 includes a driving member 21 and a connecting rod 22, and the multiple wind sweeping blades 1 include a driving blade 16 and a driven blade 17. One end of the driving blade 16 is connected to the driving member 21 so that the driving member 21 drives the driving blade 16 to rotate, and the other end of the driving blade 16 is connected to the connecting rod 22 to drive the connecting rod 22 to move along the extension direction of the shell 110. The connecting rod 22 is connected to the driven blade 17 to drive the driven blade 17 to rotate.

[0057] Specifically, Figure 3 and Figure 8 As shown, the sweeping blade 1 at the bottom of the plurality of sweeping blades 1 is a driving blade 16, and the remaining sweeping blades 1 are driven blades 17. The driving member 21 is connected to the driving blade 16 to drive the driving blade 16 to rotate, and the driving blade 16 is connected to the connecting rod 22. The rotation of the driving blade 16 can drive the connecting rod 22 to move in the up and down direction, and the up and down movement of the connecting rod 22 can drive the driven blade 17 to rotate. In this embodiment, the synchronous rotation of the plurality of sweeping blades 1 is achieved by setting the driving member 21 and the connecting rod 22.

[0058] In this embodiment, there is no specific limitation on the specific structure, setting position and connection relationship of the driving assembly 2. As long as the synchronous rotation of multiple wind sweeping blades 1 can be achieved, it falls within the protection scope of this embodiment.

[0059] For example, the driving member 21 is a motor.

[0060] The air conditioner 100 of the embodiment of the present disclosure includes the wind sweeping component 120 of any one of the above embodiments.

[0061] The disclosed embodiment arranges an inclined hole on the sweeping blade 1, adjusts the rotation angle of the sweeping blade 1 to change the drainage direction of the inclined hole, so that the main airflow of the outlet airflow flows along the extension direction of the sweeping blade 1, and the component direction of the extension direction of the inclined hole is the same as the main airflow direction of the outlet airflow, thereby reducing the impact of the airflow flowing out of the inclined hole on the main airflow, reducing the air volume loss, and improving the efficiency of the air conditioner 100.

[0062] like Fig. 9As shown, the figure is a comparison chart of the heating comfort of the air conditioner 100 in the heating mode of the present embodiment and the heating comfort of the air conditioner 100 in the heating mode in the prior art, in which a gap is provided between two adjacent sweeping blades 1 and straight holes are provided on the sweeping blades 1. In the present embodiment, the heating lower edge is used as the judgment standard, and the heating lower edge refers to the lowest boundary that the hot air can reach. The present application is located below the prior art. The heating lower edge of the present embodiment is as low as 0.2m, and the heating lower edge in the related art is as low as 0.5m.
