The embodiment of the disclosure provides an air conditioner and an air conditioner indoor unit.

Optionally, the air conditioning indoor unit is a large guide plate type air conditioning indoor unit. In the air supply process of the indoor unit of the air conditioner, the air deflector 50 firstly extends out of an air outlet of the indoor unit of the air conditioner and then rotates to guide air. Thus, the air deflector 50 is far away from the air outlet, the wind resistance of the airflow blown out from the air conditioner is small, and the noise generated at the air deflector 50 in the air supply process can be reduced. Meanwhile, compared with the air supply by rotating the air deflector 50 at the air outlet, the air deflector 50 can supply air at a larger angle and in a larger range by rotating outside the air outlet, so that the refrigerating or heating effect of the air conditioner is improved. Optionally, the indoor unit of an air conditioner provided in the embodiment of the present disclosure may also be a cabinet air conditioner or an air duct machine.

In some embodiments, the air conditioner indoor unit includes a driving mechanism for driving the air deflector to move as described below.

Optionally, two driving mechanisms are respectively disposed on two sides of the air guiding plate 50, and the driving mechanisms on the two sides drive the air guiding plate 50 to move simultaneously. The following driving mechanism can drive the air deflector 50 to extend out of the air outlet to a first preset position, and then drive the air deflector 50 to rotate. The structure and operation of the drive mechanism are described in detail below.

The embodiment of the present disclosure further provides a driving mechanism for driving the air deflector to move, as shown in fig. 1 to 19.

Fig. 2 to 4 show the position of the first transmission shaft of the crank on the chute when the air deflector closes the air outlet, which may also be referred to as the centering position of the first transmission shaft of the crank.

In some embodiments, the driving mechanism for the air deflector 50 includes a crank 10, a driving link 20, a driven link 30, and a track plate 40, the crank 10 being provided with a first transmission shaft 121; the driving connecting rod 20 is provided with a sliding chute 21, one end of the driving connecting rod 20 is rotatably connected with the air deflector 50, and the first transmission shaft 121 is slidably arranged in the sliding chute 21; one end of the driven connecting rod 30 is rotationally connected with the air deflector 50; a track plate 40 provided with a track part for defining a movement locus of the driving link 20 and the driven link 30; the crank 10 drives the driving connecting rod 20 and the driven connecting rod 30 to move under the limitation of the track portion by the sliding of the first transmission shaft 121 in the sliding slot 21, so that the air deflector 50 firstly extends out of the air outlet to a first preset position and then rotates.

As shown in fig. 5 to 9, the crank 10 further comprises an elastic pull rod 13 connected to the first transmission shaft 121. When the air deflector closes the air outlet, the elastic pull rod 13 makes the first transmission shaft 121 abut against the upper edge of the chute 21, and pushes the driving connecting rod 20 to move upwards, so that the driving connecting rod 20 pulls the air deflector to close the air outlet.

When the air outlet is closed by the air deflector, the elastic part of the elastic pull rod 13 contracts and deforms to generate an upward deformation force, the elastic pull rod 13 is connected with the first transmission shaft 121, the deformation force is transmitted to the first transmission shaft 121, the first transmission shaft 121 is abutted against the upper edge of the sliding groove 21 of the driving connecting rod 20, the driving connecting rod 20 is pushed to move upwards, and the driving connecting rod 20 pulls the air deflector to close the air outlet.

It should be understood that the "upward movement of the active link" is not limited to a vertical direction, but may also be an oblique direction upward along the movement direction of the active link 20, as long as the active link 20 can pull the air deflector to close the air outlet in the direction.

Alternatively, the direction of the deformation force generated by the contraction of the elastic portion of the elastic rod 13 is the same as the direction of the upward movement of the driving link 20. The elastic tension rod 13 is a structural member provided with an elastic portion, which may be a stretchable member such as a spring, rubber, sponge, or the like.

Optionally, the elastic pull rod 13 includes a spring 131 and a push rod 132, wherein the spring 131 is telescopically sleeved on the push rod 132. When the air deflector closes the air outlet, the spring 131 is in a contracted state, so that the first transmission shaft 121 is abutted against the upper edge of the chute 21.

The push rod 132 is sleeved with a spring 131. Alternatively, the push rod 132 may move upward or downward in a direction in which the driving link 20 moves upward, and the spring 131 may be extended and contracted in a direction in which the driving link 20 moves upward.

Optionally, the push rod 132 includes an abutment platform 1321 and a sleeve stem 1322. The abutment 1321 is connected to the first transmission shaft 121, and the abutment 1321 is provided with a land that abuts against the spring 131. The stem 1322 is connected to the platform of the abutment platform 1321, and the spring 131 is sleeved on the stem 1322.

The spring 131 includes a first resilient compression surface abutting the platform of the push rod 132, wherein the area of the first resilient compression surface is smaller than the area of the platform of the push rod 132. Thus, when the air outlet is closed, the plane can be better and more uniformly abutted against the first extrusion elastic surface of the spring 131, so that the spring 131 is extruded, and the spring 131 generates deformation extrusion force. Optionally, the platform of abutment 1321 is T-shaped with stem 1322.

Optionally, the crank 10 comprises a turning rod 12. The turning rod 12 is provided with a push slide and a through slide 123. The pushing slideway is provided with the elastic pull rod 13, and the elastic pull rod 13 can slide in the pushing slideway. The through slide 123 penetrates the push slide for the first transmission shaft 121 to slide. When the air outlet is closed by the air deflector, the elastic pull rod 13 slides in the push slideway, and meanwhile, the elastic pull rod 13 drives the first transmission shaft 121 to slide in the through slideway 123.

The first transmission shaft 121 of the crank 10 is also provided to the rotating lever 12, and the elastic pull rod 13 for bringing the first transmission shaft 121 into contact with the upper edge of the slide groove 21 of the active link 20 is also provided to the rotating lever 12 of the crank 10. Optionally, the pushing chute is slot-shaped with a bottom, and the penetrating chute 123 has no bottom and penetrates the bottom of the pushing chute. Optionally, the through slide 123 is oval.

Optionally, the push ramps include a spring-loaded ramp 124 and a loop bar motion ramp 125. The spring extension slideway 124 is provided with the through slideway 123, and the spring 131 can make extension and contraction movement in the spring extension slideway 124. The rod set slide 125 is in communication with the spring extension slide 124, and the width of the spring extension slide 124 is greater than the width of the rod set slide 125, and the rod set 1322 is slidable within the spring extension slide 124 and the rod set slide 125.

The width of the spring extension slideway 124 is slightly larger than the width of the platform of the push rod 132, for example, the difference between the width of the spring extension slideway 124 and the width of the platform is larger than zero and smaller than or equal to 0.5mm, so that the spring extension slideway 124 can better limit the extension direction of the spring 131. Optionally, the abutment 1321 of the push rod 132 also slides up and down within the spring-loaded ramp 124. The sleeve rod movement ramps 125 provide a length allowance for the downward movement of the sleeve rods 1322 under maximum compression set of the springs 131.

Alternatively, the push slide and the through slide 123 are provided in the direction from the rotation center of the crank 10 to the first transmission shaft 121. So that the push rod 132 can move upward or downward in the direction in which the driving link 20 moves upward, and the spring 131 can be extended and contracted in the direction in which the driving link 20 moves upward.

Optionally, the first transmission shaft 121 includes a roller 1211 and a connection shaft. The roller 1211 is slidable in the slide groove 21 of the driving link 20, and the connecting shaft is connected to the roller 1211. The connection shaft of the first transmission shaft 121 is connected to the abutment stage 1321 of the push rod 132. The connection shaft further comprises a sliding section 1212 located between the roller 1211 and the abutment bench 1321 and slidable along the through slide 123.

The sliding section 1212 of the connecting shaft of the roller 1211 slides in the through slide 123, so as to drive the roller 1211 of the first transmission shaft 121 to abut against the upper edge of the slide.

Optionally, when the air outlet is closed by the air deflector, the first transmission shaft 121 is located at the centering position of the sliding chute 21, an elastic abutting part protruding into the sliding chute 21 is arranged at the upper edge of the centering position of the sliding chute 21, the first transmission shaft 121 abuts against the elastic abutting part, and the first transmission shaft 121 pushes the driving connecting rod 20 to move upwards, so that the driving connecting rod 20 pulls the air deflector to close the air outlet.

The process of the crank 10 of the driving mechanism provided by the embodiment of the present disclosure, in which the elastic pull rod 13 drives the air deflector to close, is described in detail below.

When the air deflector is in the open state, the spring 131 of the elastic pull rod 13 is in the extended state, and at this time, the sliding section 1212 of the first transmission shaft 121 slides to the upper portion of the through slide 123. When the air deflector is in a closed state, the upper edge of the centering position of the sliding chute 21 abuts against the roller 1211 of the first transmission shaft 121, the spring 131 in the elastic pull rod 13 is pressed to be in a contracted state, after the spring 131 is contracted, an elastic force along the extension direction of the spring 131 is generated, and the extension direction of the spring 131 is the same as the direction in which the driving connecting rod 20 is driven to move upwards after the first transmission shaft 121 abuts against the upper edge of the sliding chute 21. The elastic force generated by the contracted spring 131 is transmitted to the roller 1211 of the first transmission shaft 121, and the roller 1211 abuts against the upper edge of the driving link 20 to push the driving link 20 to move upward, so that the driving link 20 pulls the air deflector to close the air outlet.

The following embodiments are provided to describe the structure of the crank, the driving link, the driven link, the track plate, etc. in the driving mechanism of the air deflector of the air conditioner, and the rotation process of the driving mechanism driving the air deflector.

Alternatively, the driving force for the movement of the driving link 20 is from the crank 10. The crank 10 provides a driving force for the driving link 20 to move by the sliding of the first transmission shaft 121 in the slide slot 21. One end of each of the driving connecting rod 20 and the driven connecting rod 30 is connected with the air deflector 50, and further, the driving force is transmitted to the driven connecting rod 30 through the connecting point of the air deflector 50 and the driven connecting rod 30, so as to drive the driven connecting rod 30 to move. The driving connecting rod 20 and the driven connecting rod 30 drive the air guiding plate 50 to extend out of the air outlet to a first preset position under the limitation of the track plate 40, and then drive the air guiding plate 50 to rotate. Therefore, the crank 10 can drive the connecting rod assembly to move, and further drive the air deflector 50 to extend out of the air outlet and rotate to guide air. The driving mechanism has close matching relation and simple structure. Meanwhile, the air deflector 50 extends out of the air conditioner and rotates to conduct air at a large angle, and the air supply range of the air conditioner is expanded.

Optionally, both the drive link 20 and the follower link 30 are rotatably connected to the air deflection plate 50. Alternatively, one end of the driving link 20 is provided with a first connection hole 27, and one end of the driven link 30 is provided with a second connection hole 34.

Optionally, the driving link 20 is further provided with at least two sliding columns moving along the track portion, including a first sliding column 25 at the top end and a second sliding column 26 at the middle.

Thus, the effect of limiting the movement locus of the driven link 30 by the track plate 40 is improved.

Optionally, the driven link 30 is provided with a through slide 35 penetrating through the plate surface thereof, and the plate surface of the driving link 20 opposite to the driven link 30 is provided with a sliding column which passes through the through slide 35 and moves along the rail portion.

Optionally, the track portion comprises a first track and a second track, the first track is in a herringbone shape, and the first track is used for limiting the movement redirection of the driving connecting rod 20; the second track is linear and is arranged at the lower side of the first track along the extending direction of the air deflector 50, and the second track is used for limiting the driven connecting rod 30 to do linear motion; under the constraint of the first track and the second track, the driving connecting rod 20 and the driven connecting rod 30 firstly move linearly and synchronously to drive the air deflector 50 to move to a first preset position, and then the driving connecting rod 20 moves and moves oppositely to the driven connecting rod 30, so that the air deflector 50 is driven to rotate.

In the embodiment of the present disclosure, the first preset position is a position where the air deflector 50 extends out of the air conditioner in a horizontal movement manner and is about to start to rotate, as shown in fig. 17, at this time, a certain distance is provided between the air deflector 50 and the air outlet, and the air deflector 50 can be opened upwards or downwards at the first preset position. In the embodiment of the present disclosure, the rotation position of the air deflector 50 is not limited to the first preset position, the first preset position is an initial position of the rotation of the air deflector 50, and the rotation of the air deflector 50 may be understood as rotating while extending.

Optionally, the first track comprises a first straight track 41, a first branch track 42 and a second branch track 43; the first branch rail 42 communicates with the first linear rail 41, the second branch rail 43 communicates with the first linear rail 41, and the first branch rail 42 and the second branch rail 43 extend in different directions.

In the disclosed embodiment, the first sliding column 25 of the driving link 20 moves in a first track, and the second sliding column 26 of the driving link 20 moves in a second track. When the first sliding column 25 moves from the first linear track 41 to the first branch track 42 or the second branch track 43, the driving link 20 and the driven link 30 will move relatively, and the movement of the driving link 20 is redirected.

Alternatively, the second rail includes three linear rails, i.e., a second linear rail 44, a third linear rail 45, and a fourth linear rail 46, and the follower link 30 moves linearly along the three linear rails of the second rail at all times during the extension and rotation of the air guide plate 50. Wherein the third sliding column 31 moves in the second linear track 44, the fourth sliding column 32 moves in the third linear track 45, and the fifth sliding column 33 moves in the fourth linear track 46. That is, the follower link 30 moves linearly under the constraint of three rails.

It can be understood that the direction of the first linear rail 41 and the direction of the second rail are the same as the direction in which the air deflection plate 50 protrudes from the closed state to the first preset position.

Optionally, the sliding slot 21 is linear, and the first transmission shaft 121 slides in the sliding slot 21, so as to drive the driving link 20 to move. It can be understood that the direction of the sliding chute 21 and the direction of the air guiding plate 50 extending from the closed state to the first preset position may be perpendicular to each other, or may have a preset included angle, and the application does not specifically limit the direction of the sliding chute 21.

Alternatively, the diameter of the circle formed by the movement of the first transmission shaft 121 of the crank 10 is smaller than or equal to the length of the slide slot 21. In this way, the first transmission shaft 121 of the crank 10 may rotate 90 ° in the first direction or the second direction from the initial position and then continue to rotate, and the rotation angle of the first transmission shaft 121 is not limited by the length of the slide slot 21.

The driving mechanism for the air deflector 50 provided by the embodiment of the present disclosure drives the air deflector 50 to move in the following manner:

the initial state of the moving assembly with the air deflector 50 in the closed state is shown in figure 2. When the crank 10 rotates in the first direction or the second direction from the initial position shown in fig. 2, the first transmission shaft 121 slides in the slide slot 21 of the driving link 20 to move the driving link 20 and the driven link 30. The driving link 20 moves linearly along the straight line of the first linear track 41, and the driven link 30 moves linearly along the second linear track, so as to drive the air deflector 50 to move linearly to the first predetermined position. The first predetermined position can be understood as the position of the wind deflector 50 corresponding to the first sliding column 25 of the driving link 20 moving to the end of the straight line segment. In the embodiment of the present disclosure, the first direction is a clockwise direction, and the second direction is a counterclockwise direction.

When the crank 10 rotates in the first direction and the air deflector 50 reaches the first preset position, the second transmission shaft 122 of the crank 10 moves to the first limit point a, and due to the existence of the abutting force between the second transmission shaft 122 and the first limit point a, the first sliding column 25 of the driving connecting rod 20 is provided with the driving force for selecting the track, so that the first sliding column 25 of the driving connecting rod 20 enters the first branch track 42 from the first linear track 41, the second sliding column 26 of the driving connecting rod 20 passes through the through slideway 35 of the driven connecting rod 30 to continue to move in the second linear track 44, and the movement of the driving connecting rod 20 is redirected. Meanwhile, the driven link 30 continues to move linearly along the second track, so that the air deflector 50 is opened upward by the driving link 20 and the driven link 30 together, as shown in fig. 18.

When the crank 10 rotates in the second direction, when the air deflector 50 reaches the first preset position, the second transmission shaft 122 of the crank 10 moves to the second limit point B, and due to the existence of the abutting force between the second transmission shaft 122 and the second limit point B, the driving force for selecting the track is provided for the first sliding column 25 of the driving connecting rod 20, so that the first sliding column 25 of the driving connecting rod 20 enters the second branch track 43 from the first linear track 41, the second sliding column 26 of the driving connecting rod 20 passes through the through slideway 35 of the driven connecting rod 30 to continue to move in the second linear track 44, and the movement of the driving connecting rod 20 is redirected. Meanwhile, the driven link 30 continues to move linearly along the second track, so that the air deflector 50 is opened downward by the cooperation of the driving link 20 and the driven link 30, as shown in fig. 19.

It can be understood that fig. 2, 17, 18 and 19 are for illustrating the movement state of the driving mechanism in different opening states of the air deflector, and the elastic pull rod is not shown.
