In some embodiments, the air conditioner comprises the motion mechanism for the air deflector of the air conditioner indoor unit.

The embodiment of the disclosure provides a motion mechanism and air conditioner for air conditioner indoor set aviation baffle, can realize following technical effect:

the embodiment of the disclosure provides a motion mechanism for an air conditioner indoor unit air deflector, which comprises a crank, a driving connecting rod and a driven connecting rod. The crank is provided with a rotation shaft. One end of the driving connecting rod is rotationally connected with the air deflector, and the driving connecting rod is provided with a chute for sliding the rotating shaft so that the driving connecting rod moves under the drive of the crank. One end of the driven connecting rod is rotationally connected with the air deflector, and the driving connecting rod and the driven connecting rod drive the air deflector to extend out and close the air outlet of the air conditioner indoor unit. The sliding groove is provided with a stop part, and when the air deflector is in a state of closing the air outlet, the rotating shaft of the crank is abutted against the stop part.

In the moving mechanism with the sliding chute not provided with a stop part, the program prescribes the rotation step number of the stepping motor, such as 100 pulses, in the process of closing the air deflector to opening the air deflector; the number of pulses required in theory is 95, and the redundant 5 pulses are used for over-stepping so as to ensure that the air deflector is completely opened. The step-over is understood to mean the forced rotation of the motor. In the process of opening the air deflector to closing, after the theoretical pulse number is-95, the air deflector is considered to be accurately reset. After the stepper motor shaft and the mounting hole of the crank matched with the stepper motor shaft are worn for a long time, the gap is increased, so that the error between the actual rotation angle of the motor and the theoretical angle determined by a program is increased, and then the closing gap of the air deflector is increased, thereby affecting the appearance. Therefore, when the program of the air deflector moving mechanism is set, the abrasion amount between the motor shaft and the mounting hole of the crank needs to be taken into consideration, so that the rotating shaft of the crank is always at the initial position, and the process can also be described as centering the rotating shaft of the crank, enabling the rotating shaft of the crank to be at an accurate starting point, ensuring that the air deflector completely closes the air outlet, and ensuring the accuracy of the next opening angle of the air deflector. However, since the amount of wear varies, the difficulty of ensuring the centering of the rotation shaft of the crank by the setting program increases.

In the movement mechanism provided by the embodiment of the disclosure, the sliding groove is provided with the stop part, when the air deflector is closed, only a few simple over-step procedures are needed to be added, for example, 5-20 pulses are set, and due to the stop effect of the stop part, the movement of the rotating shaft caused by redundant pulses in the over-step procedures is stopped, so that the automatic centering of the rotating shaft is realized, and the air deflector and the air outlet are completely closed.

The foregoing general description and the following description are exemplary and explanatory only and are not restrictive of the application.

The embodiment of the disclosure provides an air conditioner.

The air conditioner is a large guide plate type air conditioner, when the air deflector 50 of the air conditioner is in a closed state, the air outlet can be completely closed, and no gap exists between the air deflector 50 and the air outlet. In addition, during the air supply process of the air conditioner, the air deflector 50 extends out of the air conditioner and then rotates to guide air. In this way, the air deflector 50 is far away from the air outlet, the wind resistance of the air flow 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 deflector 50 rotating at the air outlet to supply air, the air deflector 50 rotating outside the air outlet can supply air at a larger angle and in a larger range, and the refrigerating or heating effect of the air conditioner is improved. Optionally, the air conditioner provided by the embodiment of the disclosure may also be a cabinet machine or an air duct machine.

In some embodiments, the air conditioner comprises the above-mentioned movement mechanism for driving the air deflector to extend and rotate.

Alternatively, the two sides of the air deflector 50 are respectively provided with a moving mechanism, and the moving mechanisms at the two sides simultaneously drive the air deflector 50 to move. The following movement 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 at a constant speed. The structure and the movement process of the movement mechanism are described in detail below.

The disclosed embodiments also provide a movement mechanism for extending and rotating the air deflection 50, as shown in fig. 1-13.

The motion mechanism for the air deflector 50 of the indoor unit of the air conditioner provided by the embodiment of the disclosure comprises a crank 10, a driving connecting rod 20 and a driven connecting rod 30. The crank 10 is provided with a rotation shaft 11. One end of the driving link 20 is rotatably connected to the wind deflector 50. The driving link 20 is provided with a sliding groove 21 for sliding the rotation shaft 11 so that the driving link 20 moves under the driving of the crank 10. One end of the driven connecting rod 30 is rotationally connected with the air deflector 50, the driven connecting rod 30 moves under the drive of the driving connecting rod 20, and the driving connecting rod 20 and the driven connecting rod 30 drive the air deflector 50 to extend out and close an air outlet of the indoor unit of the air conditioner.

The disclosed embodiments provide a movement mechanism including a crank 10, a driving link 20, and a driven link 30. The crank 10 can rotate under the drive of the stepping motor, the rotating shaft 11 of the crank 10 slides along the sliding groove 21 of the driving connecting rod 20, and then the driving connecting rod 20 is driven to move, and the driving connecting rod 20 drives the driven connecting rod 30 to move. The motion mechanism provided by the embodiment of the disclosure can drive the air deflector 50 to extend and rotate at the same time, so that the structure of the motion mechanism of the air deflector 50 is simplified.

Optionally, the chute 21 is provided with a stop 211, and the rotation shaft 11 of the crank 10 abuts against the stop 211 when the wind deflector 50 is in a state of closing the outlet wind.

The sliding groove 212 of the driving link without the abutting portion is shown in fig. 6. In the movement mechanism shown in fig. 6, when the wind deflector 50 finishes wind guiding to close the air outlet, the rotation shaft 11 of the crank 10 needs to be centered to ensure that the wind deflector 50 is at an accurate starting position when being opened next time. The centered position is understood here to be the middle position of the chute 212 where no abutment is provided. With the increase of the number of uses, a gap is generated between the motor shaft and the mounting shaft of the crank 10 due to friction, thus increasing the difficulty of centering the rotating shaft 11 of the crank 10 when the air deflector 50 closes the air outlet.

In the movement mechanism provided in the embodiment of the present disclosure, the chute 21 is provided with a stopper 211. Through setting up of backstop portion 211, can cooperate with simple program control, both can realize that aviation baffle 50 is in the centered state when closing the air outlet the axis of rotation 11 of crank 10 for aviation baffle 50 can close the air outlet completely, has improved the holistic aesthetic property of air conditioning indoor set, has also improved the accuracy of aviation baffle 50 next opening angle simultaneously. Alternatively, the stopper 211 may be understood as a structure higher than the bottom of the chute 21. The stop 211 may be an additional structural member of the chute 21, and may be understood as an edge of the chute 21 that can stop the rotation shaft 11 of the crank 10 from further sliding.

Optionally, the chute 21 comprises a first edge portion and a second edge portion. The first edge portion is close to the edge of the driving link 20, the second edge portion is close to the middle of the driving link 20, and the second edge portion is a stop portion 211.

The portion of the active link 20 where the chute 21 is located includes an edge portion near an edge and a middle portion near the middle. Both edges of the slide groove 21 are stop edges for stopping the rotation shaft 11 of the crank 10 from continuing to slide. The stop portion 211 is disposed at an edge of the chute 21 near the middle of the driving link 20. The term "near the middle of the driving link 20" is understood to mean closer to the middle of the driving link 20 than to the edge of the driving link 20, and is understood to mean that the second edge of the chute 21 is located at the middle of the driving link 20 where the chute 21 is located. As shown in fig. 3 and 4.

Optionally, the length of the portion of the driving link 20 where the chute 21 is located is the first length, and the length of the chute 21 is less than or equal to 1/2 of the first length.

The length of the chute 21 relative to that shown in fig. 6 is approximately equal to the first length of the portion of the active link 20 where it is located. In the movement mechanism provided in the embodiment of the present disclosure, the length of the chute 21 is less than or equal to 1/2 of the first length, as shown in fig. 3 and 4. In this way, the second edge of the chute 21 can accurately play a role of stopping, which is beneficial to the automatic centering of the rotating shaft 11 of the crank 10 when the air deflector 50 is closed.

Alternatively, the distance between the rotation center 112 of the crank 10 and the rotation shaft 11 is a first distance, and the length of the slide groove 21 is equal to the first distance, or the length of the slide groove 21 is greater than the first distance and less than twice the first distance.

The length of the sliding groove 212 without the stop, shown in fig. 6, is approximately equal to the first length of the driving link 20, and the length of the sliding groove 212, shown in fig. 6, is approximately equal to twice the first distance. According to the orientation shown in fig. 6, the rotating shaft 11 of the crank 10 slides along the half slide way on the right lower side of the slide groove 212 to drive the air deflector 50 to open upwards; the motor is reversed, and the rotating shaft 11 of the crank 10 slides along the half slide way on the left upper side of the slide groove 212 to drive the air deflector 50 to be opened downwards.

Unlike the chute 212 shown in fig. 6, which is not provided with a stopper, the chute provided in the embodiment of the present disclosure is a half chute, as shown in fig. 3 and 4. In the movement mechanism provided in the embodiment of the present disclosure, whether the air deflector 50 is opened upward or downward, the rotation shaft 11 of the crank 10 slides along the chute 21 provided in the embodiment of the present disclosure, and the length of the chute 21 is equal to the first distance, or greater than the first distance and less than twice the first distance. Further, the second edge of the chute 21 can accurately play a role of stopping by matching with the stop part 211 of the chute 21, which is beneficial to automatically centering the rotating shaft 11 of the crank 10 when the air deflector 50 is closed.

Alternatively, the chute 21 is rectilinear.

As shown in fig. 3, the second edge of the linear chute 21 located in the middle of the driving link 20 is a stop portion 211.

Optionally, the chute includes an upper arc segment 22 and a lower arc segment 23 which are in bending connection, and the lower arc segment 23 is disposed at a lower portion of the corresponding position of the upper arc segment 22.

The curved runner includes an upper arcuate segment 22 and a lower arcuate segment 23 as shown in fig. 4. The speed of extension of the deflector 50 when the chute 21 is linear is shown in fig. 12. It can be seen that the uniformity of the air deflector 50 throughout the extension is poor when the chute 21 is linear. The chute provided by the embodiment of the disclosure is a curve. The speed of extension of the deflector 50 when the chute is curved is shown in fig. 13. It can be seen that the overall extension of the deflector 50 is approximately uniform when the chute is curved relative to a linear chute. The curved chute provided by the embodiment of the present disclosure improves the uniformity of the entire extending process of the air deflector 50.

Optionally, the upper arcuate segment 22 includes a communication end and a closed end. The communicating end is one end which is in bending communication with the lower arc section 23, the closing end is the other end opposite to the communicating end, and the closing end is a stop part 211.

As shown in fig. 4, the closed end of the upper arcuate segment 22 of the chute is a stop 211. In this way, the rotation shaft 11 of the crank 10 is advantageously self-aligned when the deflector 50 is closed. Optionally, the closed end of the upper arcuate segment 22 is located in the middle of the drive link 20.

Optionally, the movement mechanism further comprises a track plate 40. The rail plate 40 is provided with a chevron rail including a straight line section and upper and lower branch sections 41 and 42 branched from the straight line section. The driving connecting rod 20 is provided with a first limit sliding block 24 sliding along the herringbone track, wherein the first limit sliding block 24 slides along the upper branch section 41, so that the air deflector 50 is opened downwards; the first limiting slider 24 slides along the lower branch section 42 to open the air deflector 50 upward.

The track plate 40 is provided with a track capable of defining the movement of the driving link 20 and the driven link 30. The track comprises a chevron track defining movement of the drive link 20, as shown in fig. 8. The chevron rail includes a straight line section extending in the direction in which the air deflection 50 extends, and an upper branch section 41 and a lower branch section 42. When the first limit slider 24 of the driving connecting rod 20 slides along the straight line segment under the driving of the rotating shaft 11 of the crank 10, the air deflector 50 extends to a first preset position. When the first limiting slide block 24 slides along the upper branch section 41, the air deflector 50 rotates while extending out at the first preset position, so that the air deflector 50 is opened downwards. When the first limiting slider 24 slides along the lower branch section 42, the air deflector 50 rotates while extending out at the first preset position, so that the air deflector 50 is opened upwards.

Optionally, the track plate 40 further comprises a linear track 43 arranged in the lower part of the herringbone track. The driving link 20 further comprises a second limit slider 25 sliding along the linear track 43. The first limit slider 24 and the second limit slider 25 are in line with the stop portion 211.

As shown in fig. 5, the driving link 20 is further provided with a second limit slider 25. The first limit slide 24 and the second limit slide 25 together define the movement of the drive link 20. The first limiting slide 24, the second limiting slide 25 and the stop portion 211 are co-linear, and it can be understood that the stop portion 211 of the chute 21 is disposed on a virtual straight line formed by connecting the first limiting slide 24 and the second limiting slide 25. In this way, the automatic centering of the rotating shaft 11 of the crank 10 is facilitated when the air deflector 50 is closed, and the closing effect of the air deflector 50 is improved.

Optionally, the driven link 30 is provided with a through-slide through the driven link 30, through which the second limit slider 25 of the driving link 20 can pass and slide along the linear rail 43 of the rail plate 40.

Optionally, the follower link 30 is provided with a third limit slider sliding along the linear track 43.

The number of the third limit sliding blocks can be multiple, and the multiple third limit sliding blocks are not on the same straight line. For example, the number of third limit sliders is 3, as shown in fig. 7, including a third limit slider 1'31, a third limit slider 2'32, and a third limit slider 3'33. Correspondingly, the rail plate 40 is provided with three linear rails extending along the extending direction of the air deflector 50, and the three third limit sliders slide along the three linear rails on the rail plate 40 respectively, so that the driven connecting rod 30 can be more stably limited to perform linear motion. Optionally, the three third limit sliding blocks are arranged in a triangle. In this way, the limit effect of the track plate 40 on the movement locus of the driven link 30 is improved.

Optionally, the movement mechanism further comprises an electromagnetic element 44. The active link 20 is provided with an attracting element that is attracted by the electromagnetic element 44. The electromagnetic element 44 is used for attracting the attraction element in the energized state, so that the limit part of the driving connecting rod 20 slides along the upper branch section 41 of the herringbone track, and the air deflector 50 is opened downwards. Optionally, the electromagnetic element 44 is further configured to slide along the lower branch section 42 of the herringbone track with the limit portion of the driving link 20 in the power-off state, and the wind deflector 50 is opened upward.

Alternatively, the "limit portion of the active link 20" may be understood as the aforementioned first limit slider 24. When the first limit slider 24 of the driving connecting rod 20 moves along the linear track to the junction of the upper branch section 41 and the lower branch section 42 of the track, the first limit slider 24 easily slides along the lower branch section 42 of the herringbone track under the gravity action of the air deflector 50, so that the air deflector 50 is opened upwards. The movement mechanism provided in the embodiment of the present disclosure further includes an electromagnetic element 44, and an attraction element that can be attracted by the electromagnetic element 44 is disposed on the driving link 20. When the electromagnetic element 44 is in the energized state, the electromagnetic element 44 attracts the attraction element, and overcomes the gravity of the air deflector 50, so that the first limit slider 24 slides along the upper branch section 41 to open the air deflector 50 downwards.

Optionally, an electromagnetic element 44 is provided at the intersection of the upper and lower branch sections 41, 42 of the herringbone track, and near one side of the upper branch section 41.

As shown in fig. 8, the electromagnetic element 44 is disposed at the junction of the herringbone tracks and near one side of the upper branch section 41. In this way, the electromagnetic element 44 is facilitated to attract the active link 20 towards the side of the upper branch section 41, so that the first limit slider 24 of the active link 20 slides along the upper branch section 41 of the herringbone track.

Optionally, the limiting portion of the driving link 20 includes a first limiting slider 24, and the attraction element is part or all of the first limiting slider 24.

A portion of the first limit slider 24 serves as a suction member. Optionally, the first limit slider 24 is cylindrical, and a portion of the cylinder near the upper branch section 41 is an attracting element. In this way, the attraction of the electromagnetic element 44 to the first limit slider 24 is facilitated.

Optionally, the track plate 40 includes a first plate face and a second plate face. The first face is provided with the chevron track, and the second face is relative with first face. Wherein the electromagnetic element 44 is disposed on the first plate surface or the second plate surface.

Alternatively, the electromagnetic element 44 may be disposed on the same first plate surface as the plate surface on which the herringbone track is disposed, which is advantageous in improving the attraction of the electromagnetic element 44 to the attraction element. Alternatively, the electromagnetic element 44 may be disposed on the second plate surface, such that the electromagnetic element 44 forms an avoidance to the movement of the driving link 20, and facilitates the driving link 20 sliding along the herringbone track on the track plate 40. Alternatively, the electromagnetic element 44 may be embedded within the track plate 40.

Optionally, the electromagnetic element 44 comprises an electromagnet. The first limit slider 24 includes an iron slide core, which is an attracting element.

The electromagnet attracts the iron slide core in the first limit slide block 24 in the electrified state, so that the first limit slide block 24 of the active connecting rod 20 slides along the upper branch section 41 of the herringbone track, and the air deflector 50 is opened downwards.

Optionally, the first limiting slider 24 further includes a sliding sleeve sleeved outside the iron sliding core. The sliding sleeve is beneficial to the smooth sliding of the first limit sliding block 24 along the herringbone track.

The mode that the motion mechanism for the air conditioner indoor unit air deflector 50 provided by the embodiment of the present disclosure drives the air deflector 50 to move is as follows:

when the wind deflector 50 is in the closed state, the rotation shaft 11 of the crank 10 is in contact with the stopper 211 of the chute 21, and the rotation shaft 11 of the crank 10 is in the centered position. When the rotation shaft 11 of the crank 10 slides along the chute 21, the limiting parts of the driving link 20 and the driven link 30 are driven to slide in the track of the track plate 40, so as to drive the driving link 20 and the driven link 30 to move. The driving link 20 moves linearly along the straight line segment of the herringbone track, and the driven link 30 moves linearly along the straight line track of the track plate 40, so as to drive the air deflector 50 to extend linearly to the first preset position. The first preset position may be understood as a position of the wind deflector 50 corresponding to the first limit slider 24 of the driving link 20 moving to the end of the straight line segment.

When the air deflector 50 reaches the first preset position, the electromagnetic element 44 is in a power-off state, under the action of gravity, the first limit slider 24 of the driving connecting rod 20 slides along the lower branch section 42 of the herringbone track, and the third limit slider of the driven connecting rod 30 continues to slide along the linear track, so that the driven connecting rod 30 moves linearly, and at this time, the driving connecting rod 20 and the driven connecting rod 30 move relatively, so as to drive the air deflector 50 to open upwards, as shown in fig. 10.

When the air deflector 50 reaches the first preset position, the electromagnetic element 44 is in an energized state, under the attraction of the electromagnetic element 44 and the attraction element on the driving connecting rod 20, the gravity of the air deflector 50 is overcome, the first limit slider 24 of the driving connecting rod 20 slides along the upper branch section 41 of the herringbone track, the third limit slider of the driven connecting rod 30 continues to slide along the linear track, so that the driven connecting rod 30 moves linearly, and at the moment, the driving connecting rod 20 and the driven connecting rod 30 move relatively to drive the air deflector 50 to open downwards, as shown in fig. 11.

Whether the air deflector 50 is opened upwards or the air deflector 50 is opened downwards, the stepping motor is reversed, and is matched with a simple stepping program, the rotating shaft 11 of the crank 10 is abutted against the stop part 211 of the chute 21, the rotating shaft 11 is in a centering state, and the air deflector 50 and the air outlet are completely closed, so that the air outlet is closed.
