As shown in connection with fig. 1-21, embodiments of the present disclosure provide a drive mechanism for an air conditioner air deflection 40.

The air conditioner comprises an indoor unit and an outdoor unit, wherein the indoor unit and the outdoor unit are connected through an online pipe, and circulation of a refrigerant between the indoor unit and the outdoor unit is achieved.

The indoor unit includes a housing 100, and the housing 100 defines an air duct and is provided with an air inlet and an air outlet 1001 communicating with the air duct. The air duct is internally provided with a heat exchanger and a fan. Under the drive of the fan, air enters from the air inlet, exchanges heat with the heat exchanger, and is blown out from the air outlet 1001.

The indoor unit further includes an air deflector 40, and the air deflector 40 is movably disposed at the air outlet 1001 for opening or closing the air outlet 1001.

The driving mechanism is in driving connection with the air deflector 40, and is used for driving the air deflector 40 to move relative to the air outlet 1001, so as to open or close the air outlet 1001.

The drive mechanism includes a linkage assembly and a guide structure.

As shown in fig. 2 and 3, the link assembly includes a first link 10 and a second link 20. The first connecting rod 10 is configured to be movably connected with the air deflector 40 and make telescopic movement along the length direction of the air duct; the second connecting rod 20 is movably connected with the air deflector 40 and performs telescopic movement along the length direction of the air duct; the guide structure is matched with the air deflector 40 and used for guiding the movement track of the air deflector 40, and comprises a guide rod 30, wherein the guide rod 30 is rotationally connected with the air deflector 40, and the extending direction of the guide rod 30 is the same as that of the first connecting rod 10 and the second connecting rod 20; the first link 10 and the second link 20 drive the air deflector 40 to move between a closed position and an open position (as shown in fig. 21), the open position includes a first open position and a second open position, and the air deflector 40 moves to drive the guide rod 30 to move linearly along its own extending direction, wherein in the first open position, the air guiding surface 404 of the air deflector 40 faces in a first air guiding direction, and in the second open position, the air guiding surface 404 of the air deflector 40 faces in a second air guiding direction, one of the first air guiding direction and the second air guiding direction faces upward, and the other one faces downward. I.e. the first wind guiding direction is downwards and the second wind guiding direction is upwards, or the first wind guiding direction is upwards and the second wind guiding direction is downwards.

The first connecting rod 10 and the second connecting rod 20 apply driving force to the air deflector 40 to drive the air deflector 40 to move, and the guide rod 30 is driven to move in the moving process of the air deflector 40, and the guide rod 30 moves linearly along the extending direction of the guide rod 30, so that the guide rod 30 has a limiting effect on the movement of the air deflector 40 and limits the movement track of the air deflector 40, so that the air deflector 40 moves among a closed position, a first open position and a second open position, namely, the air deflector 40 can be overturned.

As shown in fig. 21, in the closed position, the air deflector 40 closes the air outlet 1001. Taking the first air guiding direction facing downwards and the second air guiding direction facing upwards as an example, in the first open position, the air guiding surface 404 of the air guiding plate 40 faces downwards, so that the hot air flowing out of the air outlet 1001 is guided to flow downwards during heating. In the second open position, the air guiding surface 404 faces upward, and is adapted to guide the cool air flowing out of the air outlet 1001 to flow upward during cooling. The air conditioner has a plurality of air outlet modes due to the air deflector 40 having a first open position and a second open position.

The first link 10 and the second link 20 perform telescopic movement along the length direction of the air duct, which means that the first link 10 and the second link 20 perform telescopic movement along the length direction of the air duct, and the guide bar 30 performs linear movement, for example, the guide bar 30 performs linear movement along a direction perpendicular to the air deflector 40 at the position where the guide bar 30 is located. The air guide plate 40 has a curved surface structure, not a planar structure, and the air guide plate 40 at the position of the guide bar 30 refers to a small area on the air guide plate 40 for contacting with the guide bar 30, so long as the area is small enough, the area can be approximately a plane, and the length direction of the guide bar 30 and the direction of the linear motion of the guide bar 30 are perpendicular to the plane.

Alternatively, the first link 10 is rotatably connected to the air deflector 40 through a first rotation shaft, and as shown in fig. 17, the second link 20 is slidably connected to the air deflector 40 or rotatably connected through a second rotation shaft 210.

As shown in fig. 2, the air guiding surface 404 is provided with a first protrusion 401, and the first link 10 is rotatably connected with the first protrusion 401 through a first rotation shaft. The air guiding surface 404 is also provided with a second bulge 402, and when the second connecting rod 20 is rotationally connected with the air guiding plate 40, the second connecting rod 20 is rotationally connected with the second bulge 402 through the second rotating shaft 210; when the second connecting rod 20 is slidably connected with the air deflector 40, one of the second protrusion 402 and the second connecting rod 20 is provided with a sliding groove 403, and the other is provided with a sliding shaft 209, and the sliding shaft 209 is slidably disposed in the sliding groove 403.

Alternatively, as shown in fig. 8, the driving mechanism includes a power source, and the first link 10 includes a first connection section 101 and a second connection section 102. One end of the first connecting section 101 is in driving connection with a power source, and the power source drives the first connecting section 101 to rotate around the one end of the first connecting section 101; one end of the second connecting section 102 is rotationally connected with the first connecting section 101, and the other end of the second connecting section 102 is rotationally connected with the air deflector 40 through a first rotating shaft; the air deflector 40 sequentially passes through a closed position, a first open position and a second open position during the opening process, and moves from the closed position to the first open position, the movement direction of the second connecting section 102 is a first direction, and moves from the first open position to the second open position, the movement direction of the second connecting section 102 is a second direction, and the first direction and the second direction are opposite.

The movement direction of the second connecting section 102 is opposite from the closed position to the first open position and from the first open position to the second open position, i.e. the second connecting section 102 extends along the length direction of the air duct from the closed position to the first open position, the first open position to the second open position, the second connecting section 102 retracts along the length direction of the air duct, or the second connecting section 102 retracts along the length direction of the air duct from the closed position to the first open position, the second connecting section 102 extends along the length direction of the air duct from the first open position to the second open position. So that the first link 10 can cooperate with the second link 20 to effect the turning of the deflector 40 from the first open position to the second open position.

Alternatively, as shown in fig. 13 to 20, in the case where the second link 20 is rotatably connected to the wind deflector 40, the driving mechanism includes a power source, and the second link 20 includes a first sub-link 204 and a second sub-link 205.

The first sub-link 204 is in driving connection with a power source; one end of the second sub-link 205 is rotatably connected to the first sub-link 204, and the other end of the second sub-link 205 is rotatably connected to the air deflector 40.

The second link 20 includes a first sub-link 204 and a second sub-link 205 rotatably coupled to increase the freedom of movement of the second link 20 to effect movement of the damper 40 between the closed position, the first open position, and the second open position.

As shown in fig. 1 to 4 and fig. 8 to 12, when the second link 20 is slidably connected to the wind deflector 40, the second link 20 has an integral structure.

Optionally, the power source includes a drive member 50 and a transmission member. The driving member is in driving connection with the driving member 50, is matched with the second connecting rod 20 and is fixedly connected with the first connecting rod 10, so that the driving member 50 drives the driving member to move, and the driving member drives the second connecting rod 20 and the first connecting rod 10 to move.

The driving member 50 drives the driving member to move, and the driving member drives the second connecting rod 20 to move, so that the driving member drives the first connecting rod 10 to move together due to the fixed connection of the first connecting rod 10 and the driving member. In this sample application, the first connecting rod 10 and the second connecting rod 20 can be driven to move by one driving piece 50, and the driving piece can simultaneously drive the first connecting rod 10 and the second connecting rod 20 to move, so that the structure of the driving mechanism can be simplified.

Alternatively, as shown in fig. 1 to 4 and 8 to 20, the second link 20 is provided with gear teeth 208, and the transmission member is a non-circular gear 60 meshed with the gear teeth 208.

The non-circular gears 60 have different radiuses, so that different movement speeds of the second connecting rod 20 can be realized under the condition that the angular speed of the non-circular gears 60 is fixed, so that the first connecting rod 10 and the second connecting rod 20 have different movement speed differences, and the turning of the air deflector 40 is realized.

Specifically, since the air deflector 40 is an eversion type guide plate, if the air deflector 40 is directly rotated during the movement from the closed position to the first open position, it interferes with the duct frame, and thus it is necessary to extend the air deflector 40 a distance and then rotate it, or to extend it while rotating it, and then move it to the extended position, in which the air deflector 40 is directed toward the air outlet 1001, and then turn it from the extended position to the first open position. By designing the radius of the non-circular gear 60 such that the first link 10 and the second link 20 extend a similar distance when moving from the closed position to the extended position, the deflector 40 extends or is flipped to the extended position while extending. The guide bar 30 is extended outward in this process.

After the air deflector 40 is extended and rotated a certain distance to reach the extended position, the first link 10 and the second link 20 can perform a larger differential motion, where for example the first link 10 is extended faster and the second link 20 is extended slower, so that the air deflector 40 is turned to the first open position. The guide bar 30 continues to extend outwardly during this process.

When the air deflector 40 moves from the first open position to the second open position, the movement direction of the first link 10 and the guide bar 30 is a first movement direction, the movement direction of the second link 20 is a second movement direction, and the first movement direction is opposite to the second movement direction. For example, the first link 10 and the guide bar 30 are retracted into the duct, and the second link 20 continues to extend along the length of the duct to flip the deflector 40 to the second open position.

The guide lever 30 is rotatably connected to the air deflector 40 via a rotation shaft, and the air deflector 40 is turned around the rotation shaft from an extended position to a first open position, from the first open position to a second open position, from the first open position to the extended position, and from the second open position to the first open position.

As shown in fig. 2, a hole is formed in the first protrusion 401, a rotation shaft is formed in the guide rod 30, and the rotation shaft passes through the hole and is rotatably connected with the first protrusion 401.

The air deflector 40 turns around the rotation axis, so that the movement path of the guide rod 30 can be simplified, and the guide rod 30 can perform linear movement along the length direction of the guide rod, so that the turning of the air deflector 40 can be realized.

Alternatively, the rotation axis is parallel to the longitudinal direction of the wind deflector 40.

This allows the air outlet 1001 to be opened or closed at the same time throughout the length direction of the air outlet when the air guide 40 is turned around the rotation shaft.

The line in which the first rotation shaft is located (the rotation axis between the first link 10 and the air deflector 40) coincides with the line in which the rotation shaft is located (the rotation axis between the guide bar 30 and the air deflector 40) to achieve movement of the air deflector 40 between the closed position, the first open position, and the second open position.

In the case where the second link 20 is rotatably connected to the air deflector 40 through the second rotation shaft 210, a line in which the second rotation shaft 210 is located (a rotation axis between the second link 20 and the air deflector 40) is offset from a line in which the rotation shaft is located, so that the air deflector 40 can be turned between the extended position and the first open position, and can be turned between the first open position and the second open position.

Alternatively, a line in which the second rotation shaft 210 is located (a rotation axis between the second link 20 and the air guide plate 40) and a line in which the rotation shaft is located are sequentially provided along the width direction of the air guide plate 40.

In the case where the second link 20 is slidably connected to the air guide plate 40 by the engagement of the slide shaft 209 and the slide groove 403, the slide groove 403 extends in the width direction of the air guide plate 40. One end of the chute 403 in the length direction coincides with the projection of the rotation axis on the cross section of the air deflector 40, wherein the cross section of the air deflector 40 refers to a plane perpendicular to the length direction of the air deflector 40.

Alternatively, as shown in fig. 3, the second link 20 is provided with a concave portion 201 and a convex portion 202 that are sequentially provided along the length direction of the second link 20 (i.e., the direction in which the second link 20 performs telescopic movement along the length direction of the air duct), and the concave portion 201 and the convex portion 202 are each provided with gear teeth 208.

The second link 20 is recessed toward the surface of the non-circular gear 60 to form a concave portion 201 and projected to form a convex portion 202. The design of the concave 201 and convex 202 enables the second link 20 to match the radius of the non-circular gear 60. During the opening of the air deflector 40, the concave portion 201 and the convex portion 202 are provided in this order along the extending direction of the second link 20.

Optionally, the second connecting rod 20 is further provided with a precursor portion 203, and the precursor portion 203 is provided with gear teeth 208. Along the extending direction of the second connecting rod 20, the concave part 201, the convex part 202 and the precursor part 203 are sequentially arranged, and the non-circular gear 60 is sequentially meshed with the precursor part 203, the convex part 202 and the concave part 201 in the opening process of the air deflector 40. The curvature of the precursor 203 is smaller than the curvature of the recess 201 and smaller than the curvature of the protrusion 202.
