[0039] Reference below Figure 1-Figure 7An air supply assembly 100 and an air conditioner 1000 according to an embodiment of the present invention are described.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, the air supply assembly 100 according to the first embodiment of the present application includes: a rotating shaft 10, a first air guide group 20 and a second air guide group 30.

[0041] Among them, the first air guide group 20 and the second air guide group 30 are both arranged on the rotating shaft 10, and the rotating shaft 10 is suitable for driving the first air guide group 20 and the second air guide group 30 to rotate synchronously, and the first air guide group 20, the second air guide group 30 and the rotating shaft 10 all have an inclined angle; the first air guide group 20 and the second air guide group 30 are arranged adjacent to each other at one radial end, and far away from each other at the other radial end, so that one radial end is adjacent to the windward side to gather wind, or the other radial end is adjacent to the windward side to disperse wind.

[0042] Specifically, the rotating shaft 10 can drive the first air guide group 20 and the second air guide group 30 to rotate, and the rotating shaft 10 has an axial direction and a radial direction. In the projection direction perpendicular to the airflow flow direction, the first air guide group 20 can be divided into a first part located at one radial end and a second part located at the other radial end. Correspondingly, in the projection direction perpendicular to the airflow flow direction, the second air guide group 30 can be divided into a third part located at one radial end and a fourth part located at the other radial end. The distance between the first part and the third part gradually decreases in the direction away from the rotating shaft 10, that is, they are arranged adjacent to each other, and the distance between the second part and the third part gradually increases in the direction away from the rotating shaft 10, that is, they are arranged away from each other.

[0043] See also Figure 4 , Figure 5 and Figure 6 As shown, in the gas flow direction, the air supply component 100 has a windward side. In any plane parallel to the rotating shaft 10 and extending along the airflow direction, when one radial end of the first air guide group 20 and the second air guide group 30 is adjacent to the windward side, wind dispersion can be achieved to perform a partitioned air supply mode, and when the other radial end is adjacent to the windward side, wind gathering can be achieved to perform a centralized air supply mode. When the air guide surfaces of the first air guide group 20 and the second air guide group 30 are consistent with the airflow direction, a conventional air supply mode can be achieved, that is, the air guide surfaces do not guide the airflow.

[0044] Specifically, in the zoned air supply mode, the first air guide group 20 is located on the left and guides the airflow to the left, and the second air guide group 30 is located on the right and guides the airflow to the right. In the centralized air supply mode, the first air guide group 20 is located on the left and guides the airflow to the right, and the second air guide group 30 is located on the right and guides the airflow to the left.

[0045] That is to say, when the rotating shaft 10 is in the first position, such as: when it rotates 90° clockwise, it is in the first position, and the radial end of the first air guide group 20 and the second air guide group 30 are adjacent to the windward side in the first position, and the partitioned air supply mode can be realized. When the rotating shaft 10 is in the second position, such as: when it rotates 270° clockwise, it is in the second position, and the radial other end of the first air guide group 20 and the second air guide group 30 are adjacent to the windward side in the second position, and the centralized air supply mode can be realized. When the rotating shaft 10 is in the third position, such as: when it rotates 180° clockwise, it is in the third position, in the third position, the blades of the first air guide group 20 and the second air guide group 30 are parallel or substantially parallel to the air outlet direction, and the first air guide group 20 and the second air guide group 30 have no guiding effect or a small guiding effect on the airflow, and the conventional air supply mode can be realized.

[0046] It is understandable that the existing air supply structure that can achieve centralized air supply and zoned air supply requires the use of multiple power modules to drive two or more air guide components respectively, and the structure is complex and the cost is high. The present application drives the first air guide group 20 and the second air guide group 30 through a rotating shaft 10, so as to achieve switching between the three air supply modes, which can simplify the structure and reduce costs.

[0047] It can be understood that the inclined angle refers to other angles other than right angles or straight angles.

[0048] According to the air supply assembly 100 of the embodiment of the present application, a first air guide group 20 and a second air guide group 30 with an inclined angle are arranged on the rotating shaft 10, and the rotating shaft 10 is rotated to adjust the relative positions between the first air guide group 20 and the second air guide group 30 and the windward side to achieve switching between the zoned air supply mode, the centralized air supply mode and the conventional air supply mode. On the premise of enriching the air outlet mode and the user experience, the structure of the air supply assembly 100 can be simplified and the cost of the air supply assembly 100 can be reduced.

[0049] It should be pointed out that when the air supply component 100 is supplying air, the rotating shaft 10 can also be controlled to rotate continuously to make the airflow out of the air supply component 100 more disordered, which can also simulate the natural wind and further enrich the air outlet mode and user experience.

[0050] See also Figure 2 and Figure 3 As shown, according to some embodiments of the present application, the first air guide group 20 includes a plurality of first blades 21 , and the second air guide group 30 includes a plurality of second blades 31 , and both the first blades 21 and the second blades 31 have an inclined angle with the rotating shaft 10 .

[0051] Specifically, multiple first blades 21 and multiple second blades 31 are arranged at equal intervals on the rotating shaft 10, multiple first blades 21 extend along the first direction, and multiple second blades 31 extend along the second direction. The first direction and the second direction have an angle, and there is an inclined angle between the first direction and the rotating shaft 10, and between the second direction and the rotating shaft 10.

[0052] Thus, when the rotating shaft 10 rotates to the first position, the multiple first blades 21 can guide the wind along the first direction from the windward side to the outer side of one axial end of the rotating shaft 10, and the second blades 31 can guide the wind along the second direction from the windward side to the outer side of the other axial end of the rotating shaft 10, so as to realize the partitioned air supply mode; when the rotating shaft 10 rotates to the third position, the multiple first blades 21 can guide the wind along the first direction from the windward side to the inner side of one axial end of the rotating shaft 10, and the second blades 31 can guide the wind along the second direction from the windward side to the inner side of the other axial end of the rotating shaft 10, so as to realize the centralized air supply mode.

[0053] Furthermore, by providing a plurality of first blades 21 and a plurality of second blades 31, the wind guiding effect can be improved, and the air outlet uniformity in the centralized air supply mode and the partitioned air supply mode can be improved.

[0054] like Figure 4 , Figure 5 and Figure 6 As shown, there is a first angle between the first blade 21 and the rotating shaft 10, and there is a second angle between the second blade 31 and the rotating shaft 10, and the first angle is the same as the second angle.

[0055] Specifically, there is a first angle between the first direction and the rotating shaft 10, and there is a second angle between the second direction and the rotating shaft 10, and the first angle and the second angle are the same. Therefore, in the zoned air supply mode, the angles between the air guide directions of the first air guide group 20 and the second air guide group 30 and the rotating shaft 10 are more consistent, and the user experience of the zoned air supply mode is better. In the centralized air supply mode, the convergence effect of the airflow can also be improved.

[0056] Furthermore, the first angle and the second angle range from 30° to 75°.

[0057] Exemplarily, the first angle and the second angle can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, etc., so that the angle range of the first angle and the second angle is more reasonable, avoiding the angle being too small or too large, resulting in unclear changes in airflow in the zoned air supply mode or the centralized air supply mode, and improving the airflow guiding effect to improve the user experience.

[0058] In some embodiments, the number of the first blades 21 is different from the number of the second blades 31 , where the number of the first blades 21 is N, and the number of the second blades 31 is N±2.

[0059] Exemplarily, the number of the first blades 21 is five, and the corresponding number of the second blades 31 may be three, four, five, six, or seven.

[0060] That is to say, the number of the first blades 21 and the second blades 31 is set as close as possible to avoid a large difference in the number of the first blades 21 and the second blades 31, so that in the zoned air supply mode, the air output on both sides is similar, thereby improving the air supply effect and the user experience.

[0061] In some embodiments, the number of the first blades 21 is the same as the number of the second blades 31. Thus, the air volume of the air guide area of ​​the first air guide group 20 can be more consistent with the air volume of the air guide area of ​​the second large air guide group, further improving the user experience.

[0062] Furthermore, the first angle and the second angle are symmetrically arranged relative to the straight line angle perpendicular to the rotation axis 10 .

[0063] Specifically, the first air guide group 20 and the second air guide group 30 are respectively arranged on both sides of the center line of the rotating shaft 10, and the first blade 21 of the first air guide group 20 and the second blade 31 of the second air guide group 30 are symmetrically arranged with respect to the straight line perpendicular to the rotating shaft 10, but not symmetrically arranged in number. The number can be the same or different, so that the air supply effect between the air supply area of ​​the first air guide group 20 and the air supply area of ​​the second air guide group 30 is more consistent through the first blade 21 and the second blade 31 that are symmetrically arranged in angle.

[0064] In some embodiments, the blade surface of the first blade 21 and the blade surface of the second blade 31 are configured as an arcuate surface, a plane, or a continuous first surface and a second surface, and the first surface and the second surface have an included angle.

[0065] Exemplarily, the blade surfaces of the first blade 21 and the second blade 31 are planes. When in the third position, the planes are parallel to the airflow direction, and no airflow guidance is performed to achieve a conventional air supply mode; the blade surfaces of the first blade 21 and the second blade 31 may also be curved surfaces, which have a better air guidance effect in the first position and the second position, and when in the third position, the curved surfaces are generally parallel to the airflow direction, and a conventional air supply mode may also be achieved; the blade surfaces of the first blade 21 and the second blade 31 are constructed to include a first surface and a second surface. When in the first position, the first surface is adjacent to the windward side, and the airflow flows through the first surface and the second surface in sequence, and outward wind guidance is achieved through the second surface. When in the second position, the second surface is adjacent to the windward side, and the airflow flows through the second surface and the first surface in sequence, and inward wind guidance is achieved through the first surface. When in the third position, both the first surface and the second surface are parallel to the airflow direction.

[0066] In this way, by reasonably setting the blade shape, not only can the zoned air supply mode and the centralized air supply mode be realized, but it can also be ensured that in the conventional air supply mode, the airflow is less obstructed by the air supply component 100, the wind noise is smaller, and the user experience is better.

[0067] like Figure 1 As shown, the air supply assembly 100 further includes: a frame 40 and a driving unit 50 . The rotating shaft 10 is rotatably disposed on the frame 40 . The driving unit 50 is disposed on the frame 40 and is dynamically connected to the rotating shaft 10 .

[0068] Among them, the frame 40 is arranged on the outside of the rotating shaft 10 and the first air guide group 20 and the second air guide group 30. The frame 40 is used to fix the rotating shaft 10, and the frame 40 is suitable for forming a mounting structure, which is used to install the air supply assembly 100 to a predetermined position and can improve the structural strength of the air supply assembly 100. The driving part 50 may include a driving motor and a transmission assembly. The driving motor is used to output power. The transmission assembly is at least used to output power to the rotating shaft 10 after reducing speed and increasing torque, so as to drive the rotating shaft 10 and the first air guide group 20 and the second air guide group 30 to rotate. The rotating shaft 10 and the transmission assembly can be connected through a connecting structure.

[0069] like Figure 7 As shown, the air conditioner 1000 according to the second embodiment of the present application includes: a casing 200 and an air supply assembly 100, the casing 200 has an air outlet, and the air supply assembly 100 is arranged at the air outlet.

[0070] According to the air conditioner 1000 of the embodiment of the present application, the above-mentioned air supply component 100 is used to realize at least a zoned air supply mode, a centralized air supply mode and a conventional air supply mode, enrich the temperature adjustment mode of the air conditioner 1000, improve the use experience of the air conditioner 1000, and has a simple structure, which can reduce the cost of the air conditioner 1000.

[0071] Of course, the working mode of the air conditioner 1000 in the embodiment of the present application is not limited thereto, and the air conditioner 1000 may also have a wind sweeping mode, that is, the air supply component 100 may sweep the air.

[0072] Exemplarily, when the driving motor drives the rotating shaft 10 to rotate, the first blade 21 and the second blade 31 are driven to form air ducts in different directions, thereby driving the airflow to change; Figure 6 As shown, the projections of the first blade 21 and the second blade 31 are parallel to the airflow direction. At this time, the air outlet direction is vertically forward. As the drive motor rotates counterclockwise (in the left view direction), the first blade 21 and the second blade 31 rotate. When the counterclockwise rotation reaches 90°, the state is as follows: Figure 4 As shown, it is wide-angle dispersed air sweeping at this time, the motor rotates counterclockwise 0°-90°, and the air sweeping range is normal-partition mode;

[0073] When the driving motor rotates clockwise (in the left view direction), the first blade 21 and the second blade 31 rotate. When the clockwise rotation reaches 90°, the state is as follows: Figure 5 As shown, at this time, the air is swept in a concentrated manner, the driving motor rotates clockwise by 0°-90°, and the air sweeping range is normal-concentrated mode.

[0074] Other structures and operations of the air supply assembly 100 and the air conditioner 1000 according to the embodiment of the utility model are well known to ordinary technicians in the field and will not be repeated here.
