[0002] With the improvement of people's living standards, air conditioners have gradually become one of the essential electrical appliances in people's lives.

[0003] At the air outlet of the existing air conditioner indoor unit, there is a swing blade, which can swing left and right to change the air outlet direction and air outlet speed of the air conditioner indoor unit.

[0004] However, the swing angle of the swing blade of the existing air conditioner indoor unit relative to the air outlet direction is generally 45° to 60°. When the user needs a gentle air flow effect at a low wind speed, due to the limitation of the swing angle of the swing blade, it is impossible to achieve the gentle air flow effect at a low wind speed by adjusting the swing angle of the swing blade, thus reducing the user experience.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Utility Model

[0006] The utility model aims to solve the above technical problems, that is, to solve the problem that the swing angle of the swing blade of the existing air conditioner indoor unit is small.

By providing a plurality of grooves on the surface of the plate-shaped body, the wind speed flowing through the swing blade is slowed down, so that the air outlet is softer. By arranging the swing blades to be spaced along the length direction of the air outlet, the air outlet speed is further reduced, making the air outlet of the air conditioner indoor unit softer and improving the user experience.

[0013] In the preferred technical solution of the above air conditioner indoor unit, the included angle between the extending direction of the connecting arm and the extending direction of the plate-shaped body is 10° to 30°.

[0014] In the case of adopting the above technical solution, the present utility model sets the included angle between the extending direction of the connecting arm and the extending direction of the plate-shaped body to be 10° to 30°, which can not only avoid the driving device from colliding with the connecting arm when driving the connecting arm to rotate, but also make the driving efficiency of the driving device higher.

[0015] In the preferred technical solution of the above air conditioner indoor unit, the driving device includes a driving motor, a crank and a connecting rod.

[0019] In the preferred technical solution of the above air conditioner indoor unit, an inlet and outlet communicating with the connecting hole is further provided on the connecting rod, and the opening size of the inlet and outlet is smaller than the diameter of the rotating shaft.

[0020] In the case of adopting the above technical solution, the utility model facilitates the installation and disassembly of the rotating shaft of the connecting arm by arranging an inlet and outlet communicating with the connecting hole on the connecting rod.

[0021] In the preferred technical solution of the above air conditioner indoor unit, an installation hole is provided on the housing, and the pivotal connection part includes a base part and a cylindrical connection part.

[0035] The following describes the preferred embodiments of the utility model with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the utility model and are not intended to limit the protection scope of the utility model.

[0036] It should be noted that in the description of the utility model, the terms indicating directions or positional relationships such as "inner", "outer", "upper", "lower", "top", "bottom", "left", "right", etc. are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the utility model.

[0037] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "arrangement", "connection", and "installation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0038] Based on the problem pointed out in the background technology that the swing angle of the swing blade of the existing air conditioner indoor unit is small, the present utility model provides an air conditioner indoor unit, aiming to drive the swing blade to rotate through a driving device so that the swing blade rotates to a position parallel to the air outlet, thereby increasing the swing angle of the swing blade, reducing the air outlet speed, making the air outlet of the air conditioner indoor unit softer, and improving the user experience.

[0039] Specifically, as Figure 1 and Figure 2 shown, the air conditioner indoor unit of the present utility model includes a housing 1, a swing blade 2, and a driving device 3. The housing 1 has an air outlet 12. The swing blade 2 is installed vertically in the air outlet 12. The swing blade 2 is pivotally connected to the housing 1. The driving device 3 is installed on the housing 1 and can drive the swing blade 2 to rotate so that the swing blade 2 rotates to a position parallel to the air outlet 12.

[0040] Exemplarily, as Figure 1 and Figure 2 shown, the housing 1 of the air conditioner indoor unit of the present utility model has an air outlet 12. A duct 11 is provided inside the housing 1. The duct 11 is communicated with the air outlet 12. The swing blade 2 is installed vertically at a position close to the air outlet 12 in the duct 11. The swing blade 2 is pivotally connected to the duct 11. The driving device 3 is installed on the housing 1 and is located outside the duct 11. When the air conditioner indoor unit is in normal use, the swing blade 2 is arranged perpendicular to the air outlet 12. That is to say, the air in the duct 11 is directly blown out from the air outlet 12 without being affected by the swing blade 2. When the user needs a soft air effect, the driving device 3 can drive the swing blade 2 to rotate, reducing the wind speed by blocking part of the duct 11. However, the rotation angle of the swing blade 2 of the existing air conditioner indoor unit is generally between 45° and 60°. When the user needs a soft air effect, due to the small rotation angle of the swing blade 2 of the existing air conditioner indoor unit, the effect of the swing blade 2 blocking the duct 11 and reducing the wind speed is not ideal. The driving device 3 of the present utility model can drive the swing blade 2 to rotate to a position parallel to the air outlet 12, thereby being able to block part of the duct 11, reducing the ventilation area of the duct 11, reducing the wind speed, and thus being able to achieve the soft air supply effect and improving the user experience.

[0041] It should be noted that the present utility model does not limit the type of the driving device 3. For example, those skilled in the art can set the driving device 3 to directly drive the swinging blade 2 to rotate by a driving motor, or can also be set to drive the swinging blade 2 to rotate in the way of a driving motor + a crank + a connecting rod, etc. Such adjustments and changes to the specific type of the driving device 3 do not deviate from the principle and scope of the present utility model and should all be limited within the protection scope of the present utility model.

[0042] It should also be noted that the present utility model does not limit the installation position of the driving device 3. For example, those skilled in the art can also set the driving device 3 inside the air duct 11, etc. Such adjustments and changes to the specific installation position of the driving device 3 do not deviate from the principle and scope of the present utility model and should all be limited within the protection scope of the present utility model.

[0043] Preferably, as Figures 1 to 3 shown, the swinging blade 2 of the present utility model includes a plate-shaped body 21, a pivot connection part 22 and a connecting arm 23 which are connected in sequence. The pivot connection part 22 is pivotally connected to the housing 1, and one end of the connecting arm 23 far from the pivot connection part 22 is pivotally connected to the driving device 3. The driving device 3 can drive the connecting arm 23 to rotate around the pivot connection part 22 so that the plate-shaped body 21 rotates relative to the housing 1.

[0044] Exemplarily, as Figures 1 to 3 shown, the swinging blade 2 of the present utility model is arranged in the vertical direction. The pivot connection part 22 is located at the bottommost part and is pivotally connected to the bottom of the air duct 11. The plate-shaped body 21 is located on the side of the pivot connection part 22 close to the air outlet 12 (seen as the front side from Figure 1 ), and the connecting arm 23 is located on the side of the pivot connection part 22 far from the air outlet 12 (seen as the rear side from Figure 1 ). The rear end of the connecting arm 23 is pivotally connected to the driving device 3. The driving device 3 can drive the rear end of the connecting arm 23 to rotate around the pivot connection part 22, thereby driving the plate-shaped body 21 to rotate around the pivot connection part 22 as well.

[0045] Preferably, as Figures 1 to 3 shown, the extending direction of the connecting arm 23 of the present utility model intersects with the extending direction of the plate-shaped body 21.

[0046] Exemplarily, as Figures 1 to 3 shown, the plate-shaped body 21 of the present utility model is arranged in a direction perpendicular to the air outlet 12, that is, parallel to the air outlet direction. There is an included angle between the connecting arm 23 and the air outlet direction. Through such a setting, it can effectively avoid the driving device 3 from colliding with the connecting arm 23 when driving the connecting arm 23 to rotate.

[0047] Preferably, as Figure 3As shown, a plurality of grooves 211 are provided on the surface of the plate-shaped body 21 of the present utility model.

[0048] Exemplarily, as Figure 3 shown, a plurality of grooves 211 spaced apart are provided on the surfaces on both sides of the plate-shaped body 21 of the present utility model. By providing the grooves 211, the wind speed flowing through the swing blades 2 is slowed down, thereby making the air outlet more gentle.

[0049] Preferably, as Figure 1 and Figure 2 shown, the number of the swing blades 2 of the present utility model is multiple, and the multiple swing blades 2 are spaced apart along the length direction of the air outlet 12, and the driving device 3 can drive the multiple swing blades 2 to rotate synchronously.

[0050] Exemplarily, as Figure 1 and Figure 2 shown, the number of the swing blades 2 of the present utility model is 10, and they are spaced apart along the length direction of the air outlet 12, and the driving device 3 can drive the 10 swing blades 2 to rotate synchronously. That is to say, the rotation angles and rotation paces of the 10 swing blades 2 are the same.

[0051] It should be noted that the present utility model does not limit the number of the swing blades 2. For example, those skilled in the art can also set the swing blades 2 to be 8 or 12 spaced apart, etc. Such adjustments and changes to the specific number of the swing blades 2 do not deviate from the principle and scope of the present utility model, and should all be limited within the protection scope of the present utility model.

[0052] Preferably, as Figure 3 shown, the included angle between the extending direction of the connecting arm 23 and the extending direction of the plate-shaped body 21 of the present utility model is 10° to 30°.

[0053] Exemplarily, as Figure 3 shown, the included angle between the extending direction of the connecting arm 23 and the extending direction of the plate-shaped body 21 of the present utility model is 22.5°. That is to say, the included angle between the extending direction of the connecting arm 23 and the air outlet direction is 22.5°. Such a setting can, while avoiding the driving device 3 from colliding with the connecting arm 23 when driving the connecting arm 23 to rotate, also make the driving efficiency of the driving device 3 higher.

[0054] It should be noted that the present utility model does not limit the magnitude of the included angle between the extending direction of the connecting arm 23 and the extending direction of the plate-shaped body 21. For example, those skilled in the art can set the included angle to any value between 10° and 30°. Such adjustments and changes to the specific magnitude of the included angle between the extending direction of the connecting arm 23 and the extending direction of the plate-shaped body 21 do not deviate from the principle and scope of the present utility model, and should all be limited within the protection scope of the present utility model.

[0055] Of course, the present utility model preferably sets the included angle between the extending direction of the connecting arm 23 and the extending direction of the plate-shaped body 21 to 22.5°, which can improve the driving efficiency of the driving device 3.

[0056] Preferably, as Figure 1 and Figure 2 shown, the driving device 3 of the present utility model includes a driving motor 31, a crank 32, and a connecting rod 33. The first end of the crank 32 is fixedly connected to the driving motor 31, the second end of the crank 32 is pivotally connected to the connecting rod 33. The connecting rod 33 extends along the length direction of the air outlet 12 and is pivotally connected to a plurality of connecting arms 23. The driving motor 31 can drive the connecting rod 33 to reciprocate along the length direction of the air outlet 12 through the crank 32, thereby driving a plurality of swing blades 2 to rotate.

[0057] Exemplarily, as Figure 1 and Figure 2 shown, the driving motor 31 of the present utility model is fixedly installed on the housing 1. The first end of the crank 32 is fixedly connected to the rotating shaft of the driving motor 31, the second end of the crank 32 is pivotally connected to the rightmost end of the connecting rod 33. The connecting rod 33 extends along the length direction of the air outlet 12 into the air duct 11, and the connecting rod 33 is pivotally connected to a plurality of connecting arms 23. The driving motor 31 can drive the crank 32 to rotate, thereby driving the connecting rod 33 to reciprocate along the length direction of the air outlet 12. The connecting rod 33 then drives a plurality of swing blades 2 to rotate.

[0058] Preferably, as Figures 1 to 3 shown, a rotating shaft 231 is provided at the end of the connecting arm 23 of the present utility model, and a connecting hole 331 is provided on the connecting rod 33. The rotating shaft 231 is located in the connecting hole 331 and can rotate relative to the connecting hole 331.

[0059] Exemplarily, as Figures 1 to 3 shown, two connecting ears 232 are provided at the end of the connecting arm 23 of the present utility model. The rotating shaft 231 is installed between the two connecting ears 232. A connecting hole 331 is provided on the connecting rod 33. The rotating shaft 231 is located in the connecting hole 331, and the connecting rod 33 is located between the two connecting ears 232. The swing blade 2 and the connecting rod 33 are pivotally connected through the rotating shaft 231 and the connecting hole 331.

[0060] Preferably, as Figure 2 shown, an inlet / outlet 332 communicating with the connecting hole 331 is further provided on the connecting rod 33 of the present utility model. The opening size of the inlet / outlet 332 is smaller than the diameter of the rotating shaft 231.

[0061] Exemplarily, as Figure 2As shown in the figure, an inlet / outlet 332 communicating with the connection hole 331 is provided on the connecting rod 33 of the present utility model. The rotating shaft 231 is clamped into the connection hole 331 through the inlet / outlet 332. The opening size of the inlet / outlet 332 is smaller than the diameter of the rotating shaft 231, so as to prevent the rotating shaft 231 from disengaging from the connection hole 331.

[0062] Preferably, as Figures 1 to 3 shown in the figure, an installation hole 13 is provided on the housing 1 of the present utility model. The pivot connection portion 22 includes a base portion 221 and a cylindrical connection portion 222. The base portion 221 is connected to the plate-shaped body 21 and the connecting arm 23. The cylindrical connection portion 222 is located in the installation hole 13 and can rotate relative to the installation hole 13. The first end of the cylindrical connection portion 222 is connected to the base portion 221, and the second end of the cylindrical connection portion 222 passes through the installation hole 13. The cylindrical connection portion 222 has a strip-shaped opening 2221, and the strip-shaped opening 2221 extends from the first end of the cylindrical connection portion 222 to the second end of the cylindrical connection portion 222.

[0063] Exemplarily, as Figures 1 to 3 shown in the figure, the cylindrical connection portion 222 of the present utility model is located at the bottom end of the pivot connection portion 22. The cylindrical connection portion 222 can rotate relative to the installation hole 13. The top end of the cylindrical connection portion 222 is connected to the base portion 221, and the bottom end of the cylindrical connection portion 222 passes through the installation hole 13. One side of the base portion 221 close to the air outlet 12 is connected to the plate-shaped body 21, and the other side of the base portion 221 away from the air outlet 12 is connected to the connecting arm 23. The cylindrical connection portion 222 is provided with a through-strip-shaped opening 2221 in the vertical direction. The strip-shaped opening 2221 enables the cylindrical connection portion 222 to have a certain deformation, so that it can be more conveniently inserted into the installation hole 13.

[0064] It should be noted that the present utility model does not limit the number of the strip-shaped openings 2221. For example, those skilled in the art can set the strip-shaped openings 2221 as multiple ones spaced circumferentially along the cylindrical connection portion 222, etc. Such adjustments and changes to the specific number of the strip-shaped openings 2221 do not deviate from the principle and scope of the present utility model and should all be defined within the protection scope of the present utility model.

[0065] Preferably, as Figure 3 shown in the figure, the number of the strip-shaped openings 2221 of the present utility model is at least two and they are spaced circumferentially along the cylindrical connection portion 222.

By providing the limiting structure 2222, the cylindrical connecting portion 222 can be prevented from disengaging from the mounting hole 13.

[0069] It should be noted that the present utility model does not limit the number and structural form of the limiting structure 2222. For example, those skilled in the art can set the number of the limiting structure 2222 to be multiple, or the limiting structure 2222 can also be set as a wedge-shaped limiting block or a semi-cylindrical limiting block, etc. Such adjustments and changes to the specific number and specific structural form of the limiting structure 2222 do not deviate from the principle and scope of the present utility model and should be limited within the protection scope of the present utility model.

[0070] Preferably, as Figure 3 shown, the number of the limiting structures 2222 of the present utility model is at least two and they are distributed at intervals along the circumferential direction of the cylindrical connecting portion 222.
