DETAILED DESCRIPTION

[0031] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0032] like Figures 1 to 7 As shown, an embodiment of the present application provides a wind guide mechanism, including a louver assembly and a drive assembly.

[0033] The louver assembly includes a connecting rod 1 and multiple louvers 2, the louvers 2 have a swing center 21 and a connecting portion 22, the multiple louvers 2 are arranged in sequence along the length direction of the connecting rod 1, and the connecting portions 22 of the multiple louvers 2 are all rotatably connected to the connecting rod 1, and the swing center 21 of the multiple louvers 2 can be rotatably connected to the body of the indoor unit of the air conditioner, so that when the connecting rod 1 moves, the connecting rod 1 can drive the multiple louvers 2 to swing around their rotation centers respectively to achieve wind guiding.

[0034] The driving assembly includes a rotatable rotating wheel 3 and a movable guide rail 4, one of the rotating wheel 3 and the guide rail 4 is provided with a connecting protrusion 31, and the other is provided with a sliding groove 41, the connecting protrusion 31 is inserted into the sliding groove 41 and is configured to slide in the sliding groove 41, so that the guide rail 4 can move under the driving of the rotating rotating wheel 3. In the driving assembly, the rotating wheel 3 can rotate, the guide rail 4 can move, and the driving wheel and the guide rail 4 cooperate through the connecting protrusion 31 and the sliding groove 41 to convert the rotation of the rotating wheel 3 into the movement of the guide rail 4, so that the rotating wheel 3 can drive the guide rail 4 to reciprocate.

[0035] The connecting rod 1 of the shutter assembly is connected to the guide rail 4 of the driving assembly, and the connecting rod 1 is configured to move under the drive of the moving guide rail 4 to drive the plurality of shutters 2 to swing around their swing centers 21. The moving directions of the connecting rod 1 and the guide rail 4 may be parallel to the length direction of the connecting rod 1.

[0036] In the air guide mechanism of the embodiment of the present application, the connecting rod 1 of the louver assembly is connected to the guide rail 4 of the driving assembly. Therefore, when the rotating wheel 3 of the driving assembly rotates and drives the guide rail 4 to move back and forth, the guide rail 4 can drive the connecting rod 1 of the louver assembly to move back and forth, and the connecting rod 1 can drive multiple louvers 2 to swing back and forth around their swing centers 21 respectively to achieve air guiding of the louvers 2.

[0037] The air guide mechanism of the embodiment of the present application uses a rotating wheel 3 and a guide rail 4 to drive the shutter assembly, which is simpler than the gear and worm mechanism in the prior art, has a better cost performance while achieving the same air guide purpose, and significantly reduces costs.

[0038] In addition, the air guide mechanism of the embodiment of the present application is more concise in assembly. By connecting the guide rail 4 to the connecting rod 1 and inserting the connecting protrusion 31 into the slide groove 41, the connection and assembly of the shutter assembly and the driving assembly can be achieved, and the operation is simple.

[0039] In some exemplary embodiments, Figures 4 to 5 and Figure 7 As shown, the connecting protrusion 31 is disposed on the rotating wheel 3 and deviates from the rotation center of the rotating wheel 3; the sliding groove 41 is disposed on the guide rail 4, and the sliding groove 41 can penetrate the guide rail 4 along the thickness direction.

[0040] The connecting protrusion 31 arranged on the rotating wheel 3 deviates from the rotation center of the rotating wheel 3, so that when the rotating wheel 3 rotates, the connecting protrusion 31 can rotate around the rotation center of the rotating wheel 3, and the rotation movement of the connecting protrusion 31 has a component along the length direction of the connecting rod 1, so that the connecting protrusion 31 drives the guide rail 4 to move along the length direction of the connecting rod 1, and then drives the connecting rod 1 to move along its length direction and the louver 2 to swing along its swing center 21, so as to achieve wind guiding.

[0041] Of course, the connecting protrusion 31 may also be disposed on the guide rail 4 , and the sliding groove 41 may be disposed on the rotating wheel 3 .

[0042] In some exemplary embodiments, Figure 5 and Figure 7 As shown, the slide groove 41 includes an inclined groove section 413 arranged obliquely relative to the length direction of the connecting rod 1, that is, the extension direction (length direction) of the inclined groove section 413 is neither parallel to the length direction (length direction) of the connecting rod 1 Figure 5 and Figure 7 The left and right direction in the figure is also not perpendicular to the length direction of the connecting rod 1.

[0043] The inclined groove section 413 of the slide groove 41 is inclined relative to the length direction of the connecting rod 1, so that the inclined groove section 413 has a component along the length direction of the connecting rod 1. The component of the inclined groove section 413 along the length direction of the connecting rod 1 and the component of the rotational movement of the connecting protrusion 31 in the length direction of the connecting rod 1 cooperate to determine the movement range of the connecting rod 1 along its length direction and the swing range of the shutter 2 along its swing center 21, thereby determining the wind guiding effect of the wind guiding mechanism.

[0044] In some exemplary embodiments, Figure 5 and Figure 7 As shown, the slide 41 also includes a first slot section 411 and a second slot section 412, the first slot section 411, the inclined slot section 413 and the second slot section 412 are connected in sequence, and the first slot section 411 and the second slot section 412 are both extended in a direction perpendicular to the length direction of the connecting rod 1. Among them, the inclined slot section 413, the first slot section 411 and the second slot section 412 are all straight slot sections, and the end of the inclined slot section 413 connected to the second slot section 412 is inclined toward the side where the shutter assembly is located, so that the slide 41 can be Z-shaped as a whole.

[0045] Of course, the inclined groove segment 413 is not limited to being a straight groove segment, but can also be other shapes, such as: the inclined groove segment 413 can be an arc groove segment (such as: a circular arc groove segment or an elliptical arc groove segment), a V-shaped groove segment, etc.; the first groove segment 411 and the second groove segment 412 are not limited to being a straight groove segment extending in a direction perpendicular to the length direction of the connecting rod 1, but can also be other shapes, such as: the first groove segment 411 and the second groove segment 412 can be a straight groove segment inclined relative to the length direction of the connecting rod 1, or the first groove segment 411 and the second groove segment 412 can be an arc groove segment (such as: a circular arc groove segment or an elliptical arc groove segment), etc.

[0046] In some exemplary embodiments, Figures 5 to 7 As shown, the length of the projection of the slide groove 41 in the length direction of the connecting rod 1 is L1 (see Figure 7 , Figure 7The dotted line in the figure represents the center line of the chute 41), and the distance between the swing center 21 of the shutter 2 and the connecting portion 22 (the distance between the center line of the swing center 21 of the shutter 2 and the center line of the connecting portion 22) is L2 (see Figure 6 ), the distance between the connecting protrusion 31 and the rotation center of the rotating wheel 3 (the distance between the center line connecting the protrusion 31 and the rotation center of the rotating wheel 3) is L3 (see Figure 5 ), the relationship between L1, L2, and L3 is: L2 = L1 + L3, so that the angle range α of the shutter 2 swinging around the swing center 21 is -90° to 90°. Among them, when the extension direction of the first slot segment 411 and the second slot segment 412 is perpendicular to the length direction of the connecting rod 1, the length of the projection of the sliding groove 41 in the length direction of the connecting rod 1 is equal to the length of the projection of the inclined slot segment 413 in the length direction of the connecting rod 1.

[0047] The range of the air sweeping of the shutter 2 of the shutter assembly to the left and right (or up and down) depends on the length of the projection of the slide slot 41 in the length direction of the connecting rod 1 (i.e. Figure 7 The left-right span of the middle slide groove 41 is L1, and the distance L3 between the connecting protrusion 31 and the rotation center of the rotating wheel 3. When L2=L1+L3, the shutter 2 can rotate 90 degrees to the left and right from the initial position, for example, the shutter 2 can rotate to the left or right from the vertical state perpendicular to the length direction of the connecting rod 1 to the horizontal state parallel to the length direction of the connecting rod 1.

[0048] In some exemplary embodiments, the length of the projection of the slide groove 41 in the direction perpendicular to the length of the connecting rod 1 is L4 (see Figure 7 , Figure 7 The dotted line in the figure represents the center line of the slide groove 41), and L4≥2×L3, so that the rotating wheel 3 can drive the connecting protrusion 31 thereon to make a complete circular motion.

[0049] In some exemplary embodiments, Figure 1 , Figure 2 and Figure 4 As shown, the driving assembly further includes a driving motor 5, which is connected to the rotating wheel 3 and is configured to drive the rotating wheel 3 to rotate.

[0050] In some exemplary embodiments, Figures 1 to 5 As shown, the rotating wheel 3 is a gear. Of course, the rotating wheel 3 can also be in other forms other than the gear, such as: the rotating wheel 3 can be a rotating disk without a gear.

[0051] In some exemplary embodiments, Figure 5 and Figure 7 As shown, one end of the connecting rod 1 is provided with a fixing portion 11 , and the guide rail 4 is provided with a fixing hole 43 . The fixing portion 11 can be fixed to the fixing hole 43 to achieve a fixed connection between the connecting rod 1 and the guide rail 4 .

[0052] In some exemplary embodiments, Figure 5 and Figure 7 As shown, the guide rail 4 is also provided with a weight-reducing groove 42, which is conducive to reducing the overall weight of the guide rail 4, thereby reducing the driving force required by the driving motor 5 of the driving assembly. The weight-reducing groove 42 can be located between the slide groove 41 and the connecting rod 1, that is, the weight-reducing groove 42 can be located between the slide groove 41 and the fixing hole 43 for fixing the connecting rod 1. Of course, the weight-reducing groove 42 can also be set at other positions of the guide rail 4.

[0053] The air guide mechanism of the embodiment of the present application uses a rotating wheel 3 and a guide rail 4 to drive the shutter 2 of the shutter assembly to swing, which is simpler than the gear worm mechanism in the prior art, and has a better cost performance while achieving the purpose of sweeping the wind left and right (or up and down). In addition, the assembly of the air guide mechanism of the embodiment of the present application is also simpler. The assembly can be completed by fixing the connecting rod 1 of the shutter assembly to the fixing hole 43 on one side of the guide rail 4, and inserting the connecting protrusion 31 on the rotating wheel 3 into the slide groove 41 of the guide rail 4. Driven by the driving motor 5, the rotating wheel 3 performs a circular motion and drives the connecting protrusion 31 to perform the same circular motion; because the connecting protrusion 31 is inserted into the slide groove 41 of the guide rail 4, the connecting protrusion 31 can drive the guide rail 4 to perform a reciprocating telescopic motion; the guide rail 4 can drive the connecting rod 1 to perform a reciprocating telescopic motion, thereby driving the shutter 2 to swing left and right (or up and down) to sweep the wind.

[0054] The embodiment of the present application further provides an air conditioner, including an indoor unit, which can be a wall mounted unit or a cabinet unit. The indoor unit includes a body and an air guide mechanism provided in any of the above embodiments, the body has an air duct, the air guide mechanism is installed in the air duct and close to the air outlet of the air duct, and the swing center 21 of the shutter 2 of the air guide mechanism is rotatably connected to the body.

[0055] When the air conditioner is working, the shutter 2 of the air guide mechanism can swing to guide the air. Among them, the shutter 2 of the air guide mechanism can swing left and right to guide the air left and right. Of course, the shutter 2 of the air guide mechanism can also swing up and down to guide the air up and down.
