[0002] Currently, in recent years, household central air conditioners have the advantages of beautiful installation and small floor space because the indoor units are installed on the ceiling (also known as duct machines), and their market share is increasing continuously. Traditional mainstream duct machines only have one air outlet and cannot achieve horizontal air supply for cooling and downward air supply for heating, resulting in poor user comfort experience. To overcome the foregoing problems, a duct machine with both a horizontal air outlet and a downward air outlet has been proposed in the prior art. However, the air return opening of this duct machine needs to cooperate with the ventilation opening opened on the ceiling of the ceiling. The opening of the ventilation opening on the ceiling damages the lower wall of the ceiling, and the ceiling structure has poor consistency, reducing the aesthetic appearance.

[0003] A duct machine ceiling installation structure is provided in the related art. The duct machine ceiling installation structure includes a duct machine and a ceiling of the ceiling. The ceiling of the ceiling has a bottom wall extending in the horizontal direction and a side wall extending upward at one side edge of the bottom wall. A horizontal ventilation opening is formed on the side wall. The duct machine has a horizontal air outlet and an air return opening. The horizontal ventilation opening has an air outlet area corresponding to the horizontal air outlet and a return air area outside the air outlet area. The air return opening intakes air through the return air area.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] In the related art, when the duct machine discharges air, since the horizontal air outlet and the air return opening are on the same side wall, cross-flow occurs during the air discharge and air return processes, affecting the air discharge effect of the duct machine.

[0011] A wind deflector is rotatably arranged at the air outlet and is used to guide part of the air flow blown out by the air conditioner indoor unit to converge towards the middle of the wind deflector.

[0012] In some alternative embodiments, the wind deflector includes:

[0013] A deflector body that extends along the transverse direction of the air conditioner housing.

[0014] Flow guiding ribs are arranged on one side of the deflector body, and the flow guiding ribs extend along the air outlet direction. The number of the flow guiding ribs is multiple, and the multiple flow guiding ribs are arranged at intervals along the extending direction of the deflector body. The flow guiding ribs on both sides are gradually inclined towards the middle of the deflector body along the air outlet direction of the air outlet.

[0015] In some alternative embodiments, the shape of the flow guiding ribs is fin-shaped. The flow guiding ribs have a windward side and a leeward side, and the length dimension of the windward side is greater than the length dimension of the leeward side.

[0016] In some alternative embodiments, the height of the flow guiding ribs is greater than or equal to 10 mm and less than or equal to 15 mm.

[0017] In some alternative embodiments, the air duct assembly for the air conditioner indoor unit further includes: a wind guiding air duct that is arranged between the air outlet and the air conditioner indoor unit, with one end communicating with the air outlet and the other end being adapted to communicate with the air outlet of the air conditioner indoor unit.

This not only improves the use comfort of the air conditioner, but also can more effectively utilize the cold air or warm air, avoiding energy waste. By rotatably arranging the wind deflector, the wind deflector can be rotated to open or cover the air outlet and can change the air outlet direction of the wind deflector, thereby adjusting the air blowing direction of the indoor air conditioner. By adjusting the angle of the wind deflector, the diffusion range and intensity of the blown air flow can be controlled. For example, in summer, by adjusting the wind deflector upwards, the cold air can be more evenly distributed above the room, and through the principle of cold air sinking, the whole room can be cooled more evenly. In winter, by adjusting the wind deflector downwards, the warm air can be directly blown towards the ground, quickly raising the temperature near the ground and reducing energy waste.

[0045] Combined with Figures 1 to 5As shown, the arrows in the figure indicate the air flow direction. An embodiment of the present disclosure provides an air duct assembly for an air conditioner indoor unit 30. The air duct assembly for the air conditioner indoor unit 30 includes: an air conditioner housing 10, a grille 11, and a wind deflector 20. The air conditioner housing 10 defines a receiving cavity 102 having an opening 101. The receiving cavity 102 is adapted to receive the air conditioner indoor unit 30. The air outlet 301 of the air conditioner indoor unit 30 faces the opening 101. The area of the opening 101 corresponding to the air outlet 301 of the air conditioner indoor unit 30 is the air outlet area, and the area of the opening 101 outside the air outlet area is the air return area. The grille 11 is covered at the opening 101, and the grille 11 is provided with an air outlet 111 corresponding to the air outlet area. The wind deflector 20 is rotatably arranged at the air outlet 111 for guiding part of the air flow blown out by the air conditioner indoor unit 30 to converge towards the middle of the wind deflector 20.

[0046] Adopting the embodiment of the present disclosure, by providing the air conditioner housing 10 and defining a receiving cavity 102 with an opening 101 in the air conditioner housing 10, the receiving cavity 102 can accommodate the air conditioner indoor unit 30, playing a role in protecting the air conditioner indoor unit 30. By providing the grille 11 and covering the grille 11 at the opening 101, the grille 11 can cover the opening 101, reducing the dust flowing into the receiving cavity 102 from the air return area of the opening 101 by the outside. Secondly, it can absorb and isolate the noise generated during the operation of the air conditioner to a certain extent, making the indoor environment quieter and improving the user experience. By providing an air outlet 111 in the grille 11 corresponding to the air outlet area.

[0047] By providing the wind deflector 20 and arranging the wind deflector 20 at the air outlet 111, the wind deflector 20 can guide part of the air flow blown out by the air conditioner indoor unit 30 to converge towards the middle of the wind deflector 20, so that the air flow blown out by the air conditioner indoor unit 30 is far away from the air return area, reducing the cross-interference between the air supply air flow and the air return air flow, and avoiding the situation that the air supply air flow directly flows back to the air conditioner indoor unit 30 from the air return area or the air supply distance is short, affecting the air supply effect. This not only improves the use comfort of the air conditioner, but also can more effectively utilize the cold air or warm air, avoiding energy waste. By rotatably arranging the wind deflector 20, the wind deflector 20 can be rotated to open or cover the air outlet 111 and can change the air outlet direction of the wind deflector 20, thereby adjusting the air supply direction of the indoor air conditioner. By adjusting the angle of the wind deflector 20, the diffusion range and intensity of the air supply air flow can be controlled. For example, in summer, by adjusting the wind deflector 20 upward, the cold air can be more evenly distributed above the room, and the whole room can be cooled more evenly by the principle of cold air sinking. In winter, by adjusting the wind deflector 20 downward, the warm air can be directly blown towards the ground, quickly raising the temperature near the ground and reducing energy waste.

[0048] Optionally, the number of the air deflector 20 is plural. The plural air deflectors 20 include a first air deflector and a second air deflector, and the first air deflector and the second air deflector are arranged at intervals in the vertical direction.

[0049] By adopting the embodiment of the present disclosure, by providing the plural air deflectors 20, the air guiding effect of the air deflector 20 can be improved, the direction of the air flow can be guided more effectively, and the air flow can flow more concentratedly and orderly.

[0050] Optionally, the area of the air outlet region is smaller than the area of the air return region.

[0051] In this way, when the area of the air return region is larger than the area of the air outlet region, the indoor unit 30 of the air conditioner can collect the air in each corner of the room more effectively, ensuring that the indoor air is fully circulated.

[0052] Optionally, the area of the air outlet region can be three times the area of the air return region, the area of the air outlet region can be four times the area of the air return region, and the area of the air outlet region can also be five times the area of the air return region.

[0053] Optionally, the air deflector 20 includes a deflector body 21 and a flow guiding rib 22. The deflector body 21 is arranged to extend transversely along the air conditioner housing 10; the flow guiding rib 22 is arranged on one side of the deflector body 21 and extends along the air outlet direction. The number of the flow guiding ribs 22 is plural, and the plural flow guiding ribs 22 are arranged at intervals along the extending direction of the deflector body 21. The flow guiding ribs 22 on both sides are gradually inclined towards the middle of the deflector body 21 along the air outlet direction of the air outlet 111.

[0054] By adopting the embodiment of the present disclosure, by providing the deflector body 21, the deflector body 21 can rotate at the air outlet 111, and the deflector body 21 can cover or open the air outlet 111. By providing the flow guiding rib on one side of the deflector body 21, when the deflector body 21 opens the air outlet 111, the air supply air flow can flow out under the guidance of the flow guiding rib 22, so that the air supply air flow blows towards the specified direction. Secondly, the flow guiding rib 22 and the deflector body 21 are integrally formed, which not only plays a role in guiding the air flow, but also enhances the overall structural strength of the air deflector 20. By providing the plural flow guiding ribs 22 and arranging the plural flow guiding ribs 22 at intervals along the extending direction, the direct impact of the air flow and the eddy current phenomenon can be reduced, and the comfort and efficiency of the air supply can be improved. By arranging the flow guiding ribs 22 on both sides to be gradually inclined towards the middle of the deflector body 21 along the air outlet direction of the air outlet 111, the air supply air flows on both sides of the air outlet 111 can converge towards the middle of the air deflector 20 after flowing through the air deflector 20, thereby playing a role in reducing the cross interference between the air supply air flow and the air return air flow.

[0055] Optionally, the height of the flow guiding rib 22 is greater than or equal to 10 mm and less than or equal to 15 mm.

[0056] In this way, when the height of the flow guiding rib 22 is less than 10 mm, the air guiding effect is poor, resulting in a short air supply distance of the air supply air flow, and the cross-flow phenomenon is not significantly solved, so that the indoor temperature is uneven. When the height of the flow guiding rib 22 is greater than 15 mm, the flow guiding rib 22 has a greater influence on the air outlet resistance of the air supply air flow, resulting in a shorter air supply distance of the air supply air flow and a greater air supply noise. When the height of the flow guiding rib is greater than or equal to 10 mm and less than or equal to 15 mm, both the air guiding effect can be ensured, the air resistance can be reduced, and the air outlet noise can be reduced.

[0057] Optionally, as shown in Figure 3 multiple flow guiding ribs include a plurality of first flow guiding ribs 221 and a plurality of second flow guiding ribs 222 respectively located at different length segments of the guide plate body 21; the first flow guiding ribs 221 and the second flow guiding ribs 222 extend in the air outlet direction and are respectively gradually inclined towards the middle of the guide plate body 21.

[0058] Optionally, the multiple flow guiding ribs further include a third flow guiding rib 223, the third flow guiding rib 223 is arranged between the plurality of first flow guiding ribs 221 and the plurality of second flow guiding ribs 222, and the extending direction of the third flow guiding rib 223 is perpendicular to the extending direction of the guide plate body 21.

[0059] In this way, by arranging the third flow guiding rib 223, the third flow guiding rib 223 can separate the air supply air flows guided by the first flow guiding ribs 221 and the second flow guiding ribs 222 on both sides, avoiding the situation that the air supply distance of the air supply air flow is affected by the direct intersection and collision of two air flows in different directions.

[0060] Optionally, the number of the plurality of first flow guiding ribs 221 and the plurality of second flow guiding ribs 222 is the same, and they are symmetrically distributed about the plane where the third flow guiding rib 223 is located.

[0061] In this way, by symmetrically distributing the first flow guiding ribs 221 and the second flow guiding ribs 222 about the third flow guiding rib 223, the symmetrically distributed flow guiding ribs can ensure the balanced guidance and distribution of the air flow when passing through the air guiding plate 20. The symmetric arrangement of the first flow guiding ribs 221 and the second flow guiding ribs 222 makes the air flow directions and speeds on both sides roughly the same, thus avoiding the local overcooling or overheating phenomenon caused by uneven air flow distribution. Secondly, the symmetrically distributed flow guiding ribs help to reduce the disorder phenomenon of the air flow during the flowing process, and further reduce the noise generated when the air flow passes through the air guiding plate 20.

[0062] Optionally, along the direction of the third flow guiding rib 223 towards the first flow guiding rib 221, the inclination angles of the plurality of first flow guiding ribs 221 gradually increase.

[0063] In this way, by gradually increasing the inclination angles of the plurality of first flow guiding ribs 221 in the direction of the third flow guiding rib 223 towards the first flow guiding rib 221, the inclination angle of the first flow guiding rib 221 closer to the end of the air guiding plate 20 is larger, and the flow guiding effect is stronger. When the air flow passes through the air guiding plate 20, these flow guiding ribs with gradually increasing inclination angles can more effectively guide the air flow in a specific direction, forming a stronger local flow guiding effect, forming a more orderly and efficient air flow path, and effectively reducing the cross interference between the air supply air flow and the return air flow at the end of the air outlet 111.

[0064] Optionally, in the direction of the third flow guiding rib 223 towards the second flow guiding rib 222, the inclination angles of the plurality of second flow guiding ribs 222 gradually increase.

[0065] In this way, by gradually increasing the inclination angles of the plurality of second flow guiding ribs 222 in the direction of the third flow guiding rib 223 towards the second flow guiding rib 222, the inclination angle of the second flow guiding rib 222 closer to the end of the air guiding plate 20 is larger, and the flow guiding effect is stronger. When the air flow passes through the air guiding plate 20, these flow guiding ribs with gradually increasing inclination angles can more effectively guide the air flow in a specific direction, forming a stronger local flow guiding effect, forming a more orderly and efficient air flow path, and effectively reducing the cross interference between the air supply air flow and the return air flow at the end of the air outlet 111.

[0066] It should be noted that the inclination angle of the first flow guiding rib 221 is the included angle between the connection line of the two end points of the first flow guiding rib 221 and the air outlet direction, and the inclination angle of the second flow guiding rib 222 is the included angle between the connection line of the two end points of the second flow guiding rib 222 and the air outlet direction.

[0067] Optionally, the inclination angle of the first flow guiding rib 221 is less than or equal to 60 degrees; and / or, the inclination angle of the second flow guiding rib 222 is less than or equal to 60 degrees.

[0068] In this way, within the range of less than or equal to 60 degrees, the first flow guiding rib 221 and the second flow guiding rib 222 can effectively guide the air supply air flow to flow in a predetermined direction, reducing the disorder and eddy current phenomena of the air supply air flow during the flowing process. Secondly, the air supply air flow can maintain a certain speed when passing through the first flow guiding rib 221 and the second flow guiding rib 222, neither being too fast to cause an increase in noise and energy consumption nor being too slow to affect the flow guiding effect.

[0069] Optionally, both ends of the guide plate body 21 are provided with rotating shafts, and the rotating shafts are rotatably connected to the grille 11.

[0070] In this way, the air guiding plate 20 can be rotatably connected to the grille 11.

[0071] Optionally, the first air guiding plate and the second air guiding plate rotate independently.

[0072] In this way, each air deflector 20 can independently adjust the rotation direction, providing air flow directions at multiple angles and achieving more precise wind direction control.

[0073] Optionally, the shape of the flow guiding rib is fin-shaped. The flow guiding rib has a windward side 224 and a leeward side 225, and the length dimension of the windward side 224 is greater than that of the leeward side 225.

[0074] Adopting the embodiment of the present disclosure, in combination with Figure 3 as shown, by setting the flow guiding rib to be fin-shaped, the fin shape is a triangular-like structure. The shape of the fin helps to reduce the separation and vortex phenomena of the air flow for blowing on the surface of the flow guiding rib, enabling the air flow for blowing to flow more smoothly along the direction of the flow guiding rib and reducing the noise when the air flow for blowing passes through the flow guiding rib. Secondly, the design of the fin-shaped flow guiding rib can reduce the energy loss during the flow of the air flow for blowing, enabling the air flow for blowing to maintain a high speed and low resistance when passing through the flow guiding rib and ensuring the blowing distance of the air flow for blowing. By setting the length dimension of the windward side 224 to be greater than that of the leeward side 225, a larger windward area can be generated when the flow guiding rib is formed, thereby enhancing the guiding effect on the air flow for blowing.

[0075] Optionally, the air duct assembly for the air conditioner indoor unit 30 further includes: a guiding air duct 24, which is arranged between the air outlet 111 and the air conditioner indoor unit 30. One end of the guiding air duct 24 is communicated with the air outlet 111, and the other end of the guiding air duct 24 is adapted to be communicated with the air supply outlet 301 of the air conditioner indoor unit 30.

[0076] Adopting the embodiment of the present disclosure, by setting the guiding air duct 24, the guiding air duct 24 can communicate the air supply outlet 301 of the air conditioner indoor unit 30 with the air outlet 111, so that the air flow blown out by the air conditioner indoor unit 30 directly flows to the air outlet 111 along the guiding air duct 24, avoiding mixing with the return air flow inside the air conditioner housing 10. On the one hand, it reduces the turbulent flow and vortex phenomena inside the air conditioner housing 10, thereby improving the efficiency and speed of air supply. On the other hand, it can avoid problems such as uneven temperature and humidity change that may be caused by mixing. In addition, the guiding air duct 24 can define the path of the air flow, effectively reducing the noise generated by turbulent flow or vortex and enhancing the user experience.

[0077] Optionally, the air duct assembly for the air conditioner indoor unit 30 further includes: a first driving mechanism, which is arranged outside the guiding air duct 24 and is drivingly connected to the air deflector 20. The first driving mechanism is used to drive the air deflector 20 to rotate.

[0078] With the embodiment of the present disclosure, by providing the first driving mechanism and drivingly connecting the first driving mechanism to the air deflector 20, the first driving mechanism can drive the air deflector 20 to rotate, thereby realizing precise control of the air outlet direction of the air conditioner. Users can adjust the angle of the air deflector 20 according to actual needs to change the air supply direction, making the air supply of the air conditioner more in line with the requirements of personal comfort and usage scenarios. By arranging the first driving mechanism outside the air guiding duct 24, it is possible to prevent the first driving mechanism from blocking the air outlet of the air guiding duct 24 and reduce the air supply noise.

[0079] Optionally, the first driving mechanism includes an electric motor.

[0080] Optionally, rotating shafts are provided at both ends of the guide plate body 21, and shaft holes are provided in the air guiding duct 24. The shaft holes are adapted to the rotating shafts so that the air deflector 20 is rotatably connected to the air guiding duct 24.

[0081] Optionally, the grille 11 is detachably connected to the air conditioner housing 10.
