Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, for example, to a driving mechanism and an air conditioner for driving an air guide plate to move. Background Art

[0002] The air deflector of an air conditioner is a key component of the indoor unit. It adjusts the airflow direction, angle, and swinging of the air outlet to meet the user's varying airflow needs. For example, in cooling mode, the deflector is typically opened upward to prevent direct airflow onto the user; in heating mode, it's typically opened downward to achieve close-range airflow.

[0003] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0004] During the production process of air deflectors, from the design drawing stage to the actual production stage, it is generally considered that an air deflector that is manufactured within a reasonable tolerance range is a qualified product. Furthermore, during the installation of the air deflector with the housing of the air conditioner indoor unit, an assembly gap may be generated. As can be seen, due to the manufacturing tolerances and assembly gaps of the air deflector, a certain gap exists between the air deflector and the frame of the air outlet of the air conditioner indoor unit when the air deflector is closed, preventing the air deflector from completely closing the air outlet, affecting the appearance.

[0053] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0054] Embodiments of the present disclosure provide an air conditioner and an air conditioner indoor unit.

[0055] Optionally, the air conditioner indoor unit is a large-guide-plate type air conditioner indoor unit. During the air supply process, the air guide plate 50 first extends out of the air outlet of the air conditioner indoor unit and then rotates to guide the air. In this way, the air guide plate 50 is far away from the air outlet, and the wind resistance of the air flow blown out of the air conditioner is small, which can reduce the noise generated at the air guide plate 50 during the air supply process. At the same time, compared with rotating the air guide plate 50 at the air outlet to supply air, rotating the air guide plate 50 outside the air outlet can supply air at a larger angle and a larger range, thereby improving the cooling or heating effect of the air conditioner. Optionally, the air conditioner indoor unit provided in the embodiment of the present disclosure can also be a cabinet unit or a duct unit.

[0056] In some embodiments, the air conditioner indoor unit includes the following driving mechanism for driving the air guide plate to move.

[0057] Optionally, a drive mechanism is provided on each side of the air deflector 50, and the drive mechanisms on both sides simultaneously drive the air deflector 50 to move. The drive mechanism described below can first extend the air deflector 50 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.

[0058] The embodiment of the present disclosure also provides a driving mechanism for driving the air deflector to move, such as Figures 1 to 19 shown.

[0059] Figures 2 to 4 The figure shows the position of the first transmission shaft of the crank in the slide groove when the air guide plate closes the air outlet, which can also be called the centering position of the first transmission shaft of the crank.

[0060] In some embodiments, the driving mechanism for the air guide plate 50 includes a crank 10, an active connecting rod 20, a driven connecting rod 30 and a track plate 40, the crank 10 is provided with a first transmission shaft 121; the active connecting rod 20 is provided with a slide groove 21, one end of the active connecting rod 20 is rotatably connected to the air guide plate 50, and the first transmission shaft 121 is slidably set in the slide groove 21; one end of the driven connecting rod 30 is rotatably connected to the air guide plate 50; the track plate 40 is provided with a track portion, the track portion is used to limit the movement trajectory of the active connecting rod 20 and the driven connecting rod 30; wherein, the crank 10 drives the active connecting rod 20 and the driven connecting rod 30 to move under the limitation of the track portion through the sliding of the first transmission shaft 121 in the slide groove 21, so that the air guide plate 50 first extends out of the air outlet to the first preset position and then rotates.

[0061] like Figures 5 to 9 As shown, the crank 10 further includes 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 causes the first transmission shaft 121 to abut against the upper edge of the chute 21, and pushes the active connecting rod 20 upward, so that the active connecting rod 20 pulls the air deflector to close the air outlet.

[0062] When the air guide plate closes the air outlet, the elastic part of the elastic pull rod 13 contracts and deforms, generating an upward deformation force. The elastic pull rod 13 is connected to the first transmission shaft 121, and the deformation force is transmitted to the first transmission shaft 121, causing the first transmission shaft 121 to abut against the upper edge of the slide groove 21 of the active connecting rod 20, pushing the active connecting rod 20 to move upward, so that the active connecting rod 20 pulls the air guide plate to close the air outlet.

[0063] It is understandable that "the active connecting rod moves upward" is not limited to vertically upward, but can also be inclined upward along the movement direction of the active connecting rod 20, as long as the active connecting rod 20 can pull the air guide plate to close the air outlet in this direction.

[0064] Optionally, the direction of the deformation force generated by the contraction of the elastic part of the elastic pull rod 13 is the same as the direction of the upward movement of the active connecting rod 20. The elastic pull rod 13 is a structural member provided with an elastic part, which can be a retractable component such as a spring, rubber, sponge, etc.

[0065] 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 guide plate closes the air outlet, the spring 131 is in a contracted state, causing the first transmission shaft 121 to abut against the upper edge of the chute 21.

[0066] The push rod 132 is sleeved with a spring 131. Optionally, the push rod 132 can move upward or downward along the direction in which the active connecting rod 20 moves upward, and the spring 131 can be telescopic along the direction in which the active connecting rod 20 moves upward.

[0067] Optionally, the push rod 132 includes an abutment platform 1321 and a sleeve rod 1322. The abutment platform 1321 is connected to the first transmission shaft 121 and is provided with a platform that abuts the spring 131. The sleeve rod 1322 is connected to the platform of the abutment platform 1321, and the spring 131 is sleeved on the sleeve rod 1322.

[0068] Spring 131 includes a first extrusion elastic surface that abuts the platform of push rod 132. The area of the first extrusion elastic surface is smaller than the area of the platform of push rod 132. This allows the air deflector to more effectively and evenly abut the first extrusion elastic surface of spring 131 when closing the air outlet, thereby compressing spring 131 and generating a deformation and extrusion force. Optionally, the platform of abutment platform 1321 and sleeve rod 1322 form a T-shape.

[0069] Optionally, the crank 10 includes a rotating rod 12. The rotating rod 12 is provided with a push slide and a through slide 123. The push slide is provided with the aforementioned elastic pull rod 13, which is slidable within the push slide. The through slide 123 extends through the push slide and is used for sliding the first transmission shaft 121. When the air deflector closes the air outlet, the elastic pull rod 13 slides within the push slide, and at the same time, the elastic pull rod 13 drives the first transmission shaft 121 to slide within the through slide 123.

[0070] The first transmission shaft 121 of the crank 10 is also mounted on the rotating rod 12. The elastic pull rod 13, which is used to abut the first transmission shaft 121 against the upper edge of the slide groove 21 of the active connecting rod 20, is also mounted on the rotating rod 12 of the crank 10. Optionally, the push slide is trough-shaped with a bottom, while the through slide 123 is bottomless and penetrates the bottom of the push slide. Optionally, the through slide 123 is elliptical.

[0071] Optionally, the push slide includes a spring telescopic slide 124 and a rod-sleeving slide 125. The spring telescopic slide 124 is provided with the aforementioned through slide 123, and the spring 131 can telescope within the spring telescopic slide 124. The rod-sleeving slide 125 is connected to the spring telescopic slide 124, and the width of the spring telescopic slide 124 is greater than the width of the rod-sleeving slide 125. The rod-sleeving slide 1322 can slide within both the spring telescopic slide 124 and the rod-sleeving slide 125.

[0072] The width of the spring telescopic slide 124 is slightly greater than the width of the platform of the push rod 132. For example, the difference between the width of the spring telescopic slide 124 and the platform is greater than zero and less than or equal to 0.5 mm. This allows the spring telescopic slide 124 to better limit the extension and contraction direction of the spring 131. Optionally, the abutment 1321 of the push rod 132 also slides up and down within the spring telescopic slide 124. The sleeve rod movement slide 125 is provided with a length margin to allow the sleeve rod 1322 to move downward when the spring 131 is subjected to maximum compression deformation.

[0073] Optionally, the push slide and the through slide 123 are arranged along the direction from the rotation center of the crank 10 to the first transmission shaft 121. This allows the push rod 132 to move upward or downward along the direction in which the active connecting rod 20 moves upward, and the spring 131 to expand and contract along the direction in which the active connecting rod 20 moves upward.

[0074] Optionally, the first transmission shaft 121 includes a roller 1211 and a connecting shaft. The roller 1211 can slide within the slide groove 21 of the active connecting rod 20, and the connecting shaft is connected to the roller 1211. The connecting shaft of the first transmission shaft 121 is connected to the abutment 1321 of the push rod 132. The connecting shaft also includes a sliding section 1212 located between the roller 1211 and the abutment 1321 and capable of sliding along the through-slide 123.

[0075] The sliding section 1212 of the connecting shaft of the roller 1211 slides in the penetrating slideway 123 , thereby driving the roller 1211 of the first transmission shaft 121 to abut against the upper edge of the slideway.

[0076] Optionally, when the air guide plate closes the air outlet, the first transmission shaft 121 is in the center position of the slide groove 21, and the upper edge of the center position of the slide groove 21 is provided with an elastic abutment protruding into the interior of the slide groove 21. The first transmission shaft 121 abuts against the elastic abutment, and the first transmission shaft 121 pushes the active connecting rod 20 to move upward, so that the active connecting rod 20 pulls the air guide plate to close the air outlet.

[0077] The following describes in detail the process in which the elastic pull rod 13 of the crank 10 of the driving mechanism provided by the embodiment of the present disclosure drives the air guide plate to close.

[0078] When the air deflector is in the open position, the spring 131 of the elastic pull rod 13 is in an extended state. 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 the closed position, the upper edge of the center position of the chute 21 abuts the roller 1211 of the first transmission shaft 121, squeezing the spring 131 in the elastic pull rod 13 into a contracted state. The contraction of the spring 131 generates an elastic force in the direction of its extension. The extension direction of the spring 131 is the same as the direction in which the first transmission shaft 121 abuts the upper edge of the chute 21, driving the active connecting rod 20 upward. The elastic force generated by the contraction of the spring 131 is transmitted to the roller 1211 of the first transmission shaft 121. The roller 1211 abuts the upper edge of the active connecting rod 20, thereby pushing the active connecting rod 20 upward, causing the active connecting rod 20 to pull the air deflector to close the air outlet.

[0079] The following embodiments illustrate the structures of the crank, active connecting rod, driven connecting rod, track plate, etc. in the driving mechanism of the air guide plate of the air conditioner, and the process of the driving mechanism driving the air guide plate to rotate.

[0080] Optionally, the driving force for the movement of the active connecting rod 20 comes from the crank 10. The crank 10 provides the driving force for the movement of the active connecting rod 20 through the sliding of the first transmission shaft 121 in the slide groove 21. One end of the active connecting rod 20 and the driven connecting rod 30 are both connected to the air guide plate 50, and the driving force is then transmitted to the driven connecting rod 30 through the connection point between the air guide plate 50 and the driven connecting rod 30, driving the driven connecting rod 30 to move. Under the limitation of the track plate 40, the active connecting rod 20 and the driven connecting rod 30 first drive the air guide plate 50 to extend out of the air outlet to a first preset position, and then drive the air guide plate 50 to rotate. In this way, the above-mentioned crank 10 can drive the connecting rod assembly to move, and then drive the air guide plate 50 to extend out of the air outlet and rotate to guide the air. The driving mechanism has a close coordination relationship and a simple structure. At the same time, the air guide plate 50 extends outside the air conditioner and rotates to guide the air at a large angle, expanding the air supply range of the air conditioner.

[0081] Optionally, both the active link 20 and the driven link 30 are rotatably connected to the air deflector 50. Optionally, one end of the active link 20 is provided with a first connecting hole 27, and one end of the driven link 30 is provided with a second connecting hole 34.

[0082] Optionally, the active connecting rod 20 is further provided with at least two sliding posts moving along the track portion, including a first sliding post 25 at the top and a second sliding post 26 in the middle.

[0083] Optionally, the second plate surface of the driven connecting rod 30 opposite to the first plate surface is provided with three sliding posts, and the three sliding posts are arranged in a triangle, such as Figure 16As shown, they are respectively the third sliding post 31, the fourth sliding post 32 and the fifth sliding post 33. In this way, the limiting effect of the track plate 40 on the motion trajectory of the driven connecting rod 30 is improved.

[0084] Optionally, the driven link 30 is provided with a through slide 35 penetrating its own plate surface, and the plate surface opposite to the active link 20 and the driven link 30 is provided with a sliding column, which passes through the through slide 35 and moves along the track portion.

[0085] Optionally, the track portion includes a first track and a second track, the first track is in a herringbone shape, and the first track is used to limit the active link 20 to change direction of movement; the second track is in a straight line, and is arranged on the lower side of the first track along the direction in which the wind guide plate 50 extends, and the second track is used to limit the driven link 30 to move linearly; wherein, under the constraints of the first track and the second track, the active link 20 and the driven link 30 first move synchronously in a straight line to drive the wind guide plate 50 to a first preset position, and then, after the active link 20 changes direction, it generates relative movement with the driven link 30, thereby driving the wind guide plate 50 to rotate.

[0086] In the embodiment of the present disclosure, the first preset position is the position where the air guide plate 50 extends out of the air conditioner and is about to start rotating. Figure 17 As shown, at this time, there is a certain distance between the air deflector 50 and the air outlet, and the air deflector 50 can be opened upward or downward 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 the initial position of the rotation of the air deflector 50. The rotation of the air deflector 50 can be understood as extending and rotating at the same time.

[0087] Optionally, the first track includes a first linear track 41, a first branch track 42 and a second branch track 43; the first branch track 42 is connected to the first linear track 41, the second branch track 43 is connected to the first linear track 41, and the first branch track 42 and the second branch track 43 extend in different directions.

[0088] In the disclosed embodiment, the first sliding post 25 of the active link 20 moves within the first track, and the second sliding post 26 of the active link 20 moves within the second track. When the first sliding post 25 moves from the first linear track 41 to the first branch track 42 or the second branch track 43, the active link 20 and the driven link 30 generate relative motion, causing the active link 20 to change direction.

[0089] Optionally, the second track includes three linear tracks, namely, a second linear track 44, a third linear track 45, and a fourth linear track 46. During the extension and rotation of the air deflector 50, the driven link 30 continuously moves linearly along the three linear tracks of the second track. Specifically, the third sliding post 31 moves within the second linear track 44, the fourth sliding post 32 moves within the third linear track 45, and the fifth sliding post 33 moves within the fourth linear track 46. In other words, the driven link 30 moves linearly within the constraints of the three tracks.

[0090] It can be understood that the direction of the first linear track 41 and the direction of the second track are the same as the direction in which the air guide plate 50 extends from the closed state to the first preset position.

[0091] Optionally, the chute 21 is linear, and the first transmission shaft 121 slides within the chute 21, thereby driving the movement of the active connecting rod 20. It is understood that the direction of the chute 21 and the direction in which the air deflector 50 extends from the closed state to the first preset position can be perpendicular or at a predetermined angle. This application does not specifically limit the direction of the chute 21.

[0100] The driving mechanism for the air deflector 50 provided in the embodiment of the present disclosure drives the air deflector 50 to move in the following manner:

[0101] The initial state of the moving assembly of the wind deflector 50 in the closed state is as follows: Figure 2 As shown. When the crank 10 is Figure 2When the initial position shown rotates in the first or second direction, the first transmission shaft 121 slides within the slide groove 21 of the active connecting rod 20 to drive the active connecting rod 20 and the driven connecting rod 30 to move. The active connecting rod 20 moves linearly along the straight section of the first linear track 41, and the driven connecting rod 30 moves linearly along the second track, thereby driving the air deflector 50 to move linearly to the first preset position. The first preset position can be understood as the position of the air deflector 50 corresponding to when the first sliding post 25 of the active connecting rod 20 moves to the end of the straight section. In the disclosed embodiment, the first direction is clockwise, and the second direction is counterclockwise.

[0102] When the crank 10 rotates in the first direction and the air guide plate 50 reaches the first preset position, the second transmission shaft 122 of the crank 10 moves to the first limit point A. Due to the abutment force between the second transmission shaft 122 and the first limit point A, the first sliding column 25 of the active connecting rod 20 is provided with a driving force to select the track, so that the first sliding column 25 of the active connecting rod 20 enters the first branch track 42 from the first linear track 41, and the second sliding column 26 of the active connecting rod 20 passes through the through slide 35 of the driven connecting rod 30 and continues to move in the second linear track 44, and the active connecting rod 20 changes direction. At the same time, the driven connecting rod 30 continues to move linearly along the second track. In this way, the air guide plate 50 is opened upward under the joint drive of the active connecting rod 20 and the driven connecting rod 30, as shown in FIG. Figure 18 shown.

[0103] When the crank 10 rotates in the second direction and the air guide plate 50 reaches the first preset position, the second transmission shaft 122 of the crank 10 moves to the second limit point B. Due to the abutment force between the second transmission shaft 122 and the second limit point B, the first sliding column 25 of the active connecting rod 20 is provided with a driving force to select the track, so that the first sliding column 25 of the active connecting rod 20 enters the second branch track 43 from the first linear track 41, and the second sliding column 26 of the active connecting rod 20 passes through the through slide 35 of the driven connecting rod 30 and continues to move in the second linear track 44, and the active connecting rod 20 changes direction. At the same time, the driven connecting rod 30 continues to move linearly along the second track. In this way, the air guide plate 50 opens downward under the joint drive of the active connecting rod 20 and the driven connecting rod 30, as shown in FIG. Figure 19 shown.

[0104] It is understandable that Figure 2 、 Figure 17 、 Figure 18 、 Figure 19 This is to demonstrate the motion state of the driving mechanism in different opening states of the air deflector, wherein the elastic pull rod is not shown.
