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 includes a drive mechanism for extending and rotating the air deflection plate.

Optionally, driving mechanisms are respectively arranged at two sides of the air deflector 50, and the driving mechanisms at two sides drive the air deflector 50 to move at the same time. The driving mechanism described below can drive the air deflector 50 to extend out of the air outlet to the first preset position, and then drive the air deflector 50 to rotate at a constant speed. The structure and movement of the drive mechanism will be described in detail below.

The disclosed embodiments also provide a drive mechanism for extending and rotating the air deflection 50, as shown in fig. 1-14.

The driving mechanism for the air deflector 50 provided in the embodiment of the present disclosure includes a crank 10, a driving link 20 and a driven link 30. The crank 10 is provided with a first rotational axis 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 for the first rotation shaft 11 to slide 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 drive mechanism provided by the embodiments of the present disclosure includes 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 first rotating shaft 11 of the crank 10 slides along the sliding groove 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 driving 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 driving mechanism of the air deflector 50 is simplified.

Optionally, the chute is curved.

Fig. 5 shows a straight chute 27. The movement track generated after the first rotation shaft 11 of the crank rotates along the rotation center 12 is circular, and when the first rotation shaft 11 which performs circular movement slides in the linear chute 27, the driving link 20 is driven by the driving force, however, the extending speed of the air deflector 50 driven by the driving link 20 and the driven link 30 is shown in fig. 12. As can be seen from fig. 12, under the driving force generated by the movement of the first rotating shaft 11 of the crank along the linear chute 27, the speed at which the driving link 20 and the driven link 30 drive the air deflector 50 to extend gradually changes, the uniformity is poor, and the extending stability of the air deflector 50 is further affected.

The chute provided by the embodiment of the disclosure is a curved chute, so that the first rotation shaft 11 of the crank moves along the curved chute, the uniformity of the linear pushing force generated by the movement of the first rotation shaft 11 is improved, the driving connecting rod 20 and the driven connecting rod 30 can drive the air deflector 50 to stretch out at a relatively uniform speed, and the stability of the stretching process of the air deflector 50 is improved. It will be appreciated that the driving mechanism provided in the embodiments of the present disclosure may simultaneously drive the air deflector 50 to extend and rotate, and the extending of the air deflector 50 is still accompanied by the rotating process herein, that is, the rotating process herein may be understood as "extending and rotating. The curved chute provided in the embodiment of the present disclosure improves the uniformity of the extending speed of the air deflector 50, where the extending speed includes the extending speed of the air deflector 50 when the air deflector 50 extends linearly, and also includes the extending speed of the air deflector 50 during rotation. The curve chute provided by the embodiment of the disclosure improves the uniformity of the extending speed of the air deflector 50 in the whole movement process, and further improves the stability of the air deflector 50 in the whole movement process. Alternatively, the direction of the pushing force generated by the first rotating shaft of the crank is the same as the direction when the air deflector stretches out linearly. Similarly, the first rotating shaft of the crank is reversed, so that the air deflector can be driven to retract into the air outlet.

Alternatively, a "curved chute" may be understood as a chute in which part or all of the shape is curved. A curve may be understood as a line having an arc, such as a regular circular arc, an elliptical arc, or other irregular line having an arc, etc.

Alternatively, the curved runner may be an elliptical runner. For example, two semi-elliptical shaped grooves may be formed by connecting together. Alternatively, the arc lengths of the two semi-ellipses are not equal. In this way, the uniform speed of the pushing force generated by the first rotating shaft 11 is further improved, and the stability of the extending process of the air deflector 50 is improved.

Optionally, the curved runner includes a first curved section comprising a first upper curved section 21 and a first lower curved section 22. The first lower arc-shaped section 22 is in bending communication with the first upper arc-shaped section 21, and the first lower arc-shaped section 22 is arranged at the lower part of the corresponding position of the first upper arc-shaped section 21.

As shown in fig. 3, the first curved section is formed of a first upper arc section 21 and a first lower arc section 22 which are communicated with each other. Optionally, the bending direction of the first upper arc-shaped section 21 is opposite to that of the first lower arc-shaped section 22, so that the uniformity of the extending speed of the air deflector 50 is further improved. As shown in fig. 3, the first upper arc-shaped section is bent downward and the first lower arc-shaped section is bent upward.

Optionally, the arc length of the first upper arc segment 21 is greater than the arc length of the first lower arc segment 22.

The lengths of the two arc segments are unequal, and the arc length of the first upper arc segment 21 is greater than the arc length of the first lower arc segment 22. When the first rotating shaft 11 of the crank moves along the first upper arc-shaped section 21, the driving connecting rod 20 and the driven connecting rod 30 drive the air deflector 50 to extend linearly, and meanwhile, the first rotating shaft 11 continues to move along the first upper arc-shaped section 21, and the driving connecting rod 20 and the driven connecting rod 30 can drive the air deflector 50 to rotate; when the first rotating shaft 11 of the crank moves to the first lower arc-shaped section 22, the driving connecting rod 20 and the driven connecting rod 30 drive the air deflector 50 to rotate continuously until the air deflector 50 is opened to a set angle or a maximum angle.

Alternatively, the first upper arc segment 21 is semi-elliptical and the first lower arc segment 22 is semi-elliptical.

The first upper arc-shaped section 21 and the first lower arc-shaped section 22 are both semi-elliptical, and the arc length of the first upper arc-shaped section 21 is greater than that of the first lower arc-shaped section 22, as shown in fig. 3. In this way, the uniformity of the linear pushing force generated by the first rotating shaft 11 is further improved, and the stability of the extending process of the air deflector 50 is improved. Alternatively, the first upper arc segment 21 includes a first end point communicating with the second upper arc segment 23 and a second end point communicating with the first lower arc segment 22, and a linear distance between the first end point and the second end point of the first upper arc segment 21 is equal to a radius of a circle formed by rotation of the first rotation shaft 11 of the crank. In this way, the first rotation shaft 11 can be smoothly moved to the first lower arc-shaped section 22 through the first upper arc-shaped section 21.

Optionally, the curved chute further comprises a second curved section symmetrical to the first curved section, the second curved section comprising a second upper curved section 23 and a second lower curved section 24. The second lower arc-shaped section 24 is in bending communication with the second upper arc-shaped section 23, and the second lower arc-shaped section 24 is arranged at the lower part of the corresponding position of the second upper arc-shaped section 23. Wherein the first upper arc segment 21 is in communication with the second upper arc segment 23.

Similarly, the arc length of the second upper arc segment 23 is greater than the arc length of the second lower arc segment 24.

The lengths of the two arc segments are unequal, and the arc length of the second upper arc segment 23 is greater than the arc length of the second lower arc segment 24. When the first rotating shaft 11 of the crank moves along the second upper arc-shaped section 23, the driving connecting rod 20 and the driven connecting rod 30 drive the air deflector 50 to extend linearly, and meanwhile, the first rotating shaft 11 continues to move along the second upper arc-shaped section 23, and the driving connecting rod 20 and the driven connecting rod 30 can drive the air deflector 50 to rotate; when the first rotating shaft 11 of the crank moves to the second lower arc-shaped section 24, the driving connecting rod 20 and the driven connecting rod 30 drive the air deflector 50 to rotate continuously until the air deflector 50 is opened to a set angle or a maximum angle.

Alternatively, the second upper arc segment 23 is semi-elliptical and the second lower arc segment 24 is semi-elliptical.

The second upper arc-shaped section 23 and the second lower arc-shaped section 24 are both semi-elliptical, and the arc length of the second upper arc-shaped section 23 is greater than the arc length of the second lower arc-shaped section 24, as shown in fig. 3. In this way, the uniformity of the linear pushing force generated by the first rotating shaft 11 is further improved, and the stability of the extending process of the air deflector 50 is improved. Optionally, the second upper arc segment 23 includes a third end point that is in communication with the first upper arc segment 21 and a fourth end point that is in communication with the second lower arc segment 24, and a linear distance between the third end point and the fourth end point of the second upper arc segment 23 is equal to a radius of a circle formed by rotation of the first rotation axis 11 of the crank. In this way, the first rotation shaft 11 can be smoothly moved to the second lower arc-shaped section 24 through the second upper arc-shaped section 23.

Optionally, the arc length and arc of the first upper arc segment 21 and the second upper arc segment 23 are equal, and the arc length and arc of the first lower arc segment 22 and the second lower arc segment 24 are equal. The curved chute comprises a first curved section and a second curved section which are symmetrically arranged and are communicated with each other, and can also be called a hyperbolic chute. When the first rotation shaft 11 of the crank slides along the first upper arc section 21 and the first lower arc section 22 of the first curve section, the air deflector 50 opens upward; when the motor is reversed and the first rotating shaft 11 of the crank slides along the second upper arc section 23 and the second lower arc section 24 of the second curve section, the air deflector 50 is opened downwards. Alternatively, the curved runner is a butterfly wing, as shown in fig. 3.

When the first rotating shaft 11 of the crank slides along the butterfly wing type chute shown in fig. 3, the extending speed of the driving connecting rod 20 and the driven connecting rod 30 in the process of driving the air deflector 50 to move is shown in fig. 13. As can be seen in fig. 13, the speed of extension of the deflector 50 is relatively uniform throughout the movement. Compared with the linear chute 27, the butterfly wing type chute provided by the embodiment of the disclosure greatly improves the uniformity of the extending speed of the air deflector 50 in the whole moving process, and further improves the stability of the extending process of the air deflector 50.

Alternatively, the shape of the chute is obtained by fitting the motion track of the first rotating shaft 11 on the driving link 20 during the extending and rotating process of the air deflector 50.

As shown in fig. 5, when the shape of the chute is limited to be linear, the uniformity of the extending speed of the air deflector 50 is poor in the whole movement process of the air deflector 50 due to the pushing force obtained by the sliding of the first rotating shaft 11 of the crank in the linear chute 27, and the stability of the air deflector 50 in the movement process is affected. In the embodiment of the disclosure, the shape of the chute is obtained by fitting the motion trail of the first rotating shaft 11 of the crank on the driving connecting rod 20 based on the extending and rotating process of the air deflector 50, so that the shape of the chute and the setting position on the driving connecting rod 20 more meet the requirements of uniform speed, extending distance, rotating angle and the like in the extending and rotating process of the air deflector 50, and the stability and controllability of the whole motion process of the air deflector 50 are improved.

Optionally, the shape of the chute is obtained by fitting the motion track of the first rotation shaft on the driving link 20 during the extending and rotating process of the air deflector 50, including: the air deflector 50 is controlled to stretch out and rotate at a constant speed, and the movement track formed by the first rotating shaft 11 on the driving connecting rod 20 is in the shape of a chute.

On the basis of limiting the uniform extension and uniform rotation of the air deflector 50, the motion track formed by the first rotating shaft on the driving connecting rod 20 is used as the shape of the sliding groove, so that the accuracy of limiting the shape of the sliding groove is further improved, and the uniform speed and stability of the air deflector 50 in the whole motion process are further improved. It is understood that "uniform rotation" herein is uniform of the speed of linear protrusion included in rotation while protrusion.

Optionally, the air deflector 50 is controlled to extend and rotate at a constant speed, and a movement track formed by the first rotating shaft 11 on the driving connecting rod 20 is in a shape of a chute, which includes: the air deflector 50 is controlled to extend out at a constant speed and open upwards at a constant speed, the motion track formed by the first rotating shaft 11 on the driving connecting rod 20 is one part of the shape of the sliding groove, the air deflector 50 is controlled to extend out at a constant speed and open downwards at a constant speed, and the motion track formed by the first rotating shaft 1 on the driving connecting rod 20 is the other part of the shape of the sliding groove.

When the control air deflector 50 is extended out at a constant speed and opened upwards at a constant speed, the motion track formed by the first rotating shaft 11 on the driving connecting rod 20 is a part of the shape of a chute; when the motor is controlled to rotate reversely and the air deflector 50 stretches out at a constant speed and is opened downwards at a constant speed, the motion track formed by the first rotating shaft on the driving connecting rod 20 is the other part of the chute shape. The shape of the chute provided by the embodiment of the disclosure improves the uniformity and stability of the whole movement process when the air deflector 50 is opened upward and downward.

Alternatively, the fitted chute is shaped like a butterfly wing, as shown in fig. 3, and after the first rotation shaft 11 of the crank slides in the butterfly wing chute, the extending speed of the air deflector 50 during the whole movement is shown in fig. 13. It can be seen that the shape of the chute obtained by fitting according to the embodiment of the present disclosure greatly improves the uniformity and stability of the air deflector 50 during the movement process.

Alternatively, the driving link 20 is provided with a curved chute for the sliding of the first rotation shaft 11 of the crank, comprising a first upper arc segment and a first lower arc segment in a bent communication. The motion mechanism of the air deflector 50 further comprises an electromagnetic element, and the driving connecting rod 20 is provided with an attraction element which can be attracted by the electromagnetic element, and the electromagnetic element is used for attracting the attraction element in the electrified state so as to enable the first rotating shaft to slide along the lower arc section of the curved chute.

In the initial state, the first rotation axis 11 of the crank is located at a first end point of the upper arc-shaped section, as shown in fig. 1. The first rotating shaft 11 of the crank slides along the upper arc section to drive the air deflector 50 to linearly extend to the first preset position, and then the air deflector 50 is driven to rotate continuously. When the first rotating shaft 11 rotates to the connection position between the upper arc-shaped section and the lower arc-shaped section, the driving connecting rod 20 has a sinking trend due to the gravity action of the driving connecting rod 20, and at this time, the first rotating shaft 11 has a trend of continuously and preferentially sliding along the upper arc-shaped section instead of sliding along the lower arc-shaped section according to the setting. Thus, the uniformity and stability of the air deflector 50 in the rotation process are affected, and even the air deflector 50 is blocked in the rotation process, so that the normal movement of the air deflector 50 is affected. In the driving mechanism provided by the embodiment of the disclosure, the electromagnetic element 44 is provided, when the first rotating shaft 11 of the crank slides to the communication position of the first upper arc section and the first lower arc section, the electromagnetic element 44 is controlled to be electrified to attract the attraction element arranged on the driving connecting rod 20, the attraction effect of the electromagnetic element 44 overcomes the sinking trend of the driving connecting rod 20 under the action of gravity, so that the whole driving connecting rod 20 has the lifting trend, and the first rotating shaft 11 of the crank further slides along the set lower arc section. The rotational angular velocity obtained during the movement of the air deflector 50 in the driving mechanism provided with the electromagnetic element 44 according to the embodiment of the present disclosure is shown in fig. 14. It can be seen that in the driving mechanism provided in the embodiment of the present disclosure, through the arrangement of the electromagnetic element, uniformity of rotational angular velocity formed in the rotation process of the air deflector 50 is improved, and thus, stability of movement of the air deflector 50 is improved.

Optionally, the drive mechanism provided by the embodiments of the present disclosure further includes a track plate 40. The rail plate 40 is provided with a herringbone rail including a straight line section and upper and lower branch sections 41 and 42 branched from the straight line section, wherein an electromagnetic element is provided at the intersection of the upper and lower branch sections 41 and 42, as shown in fig. 8.

As shown in fig. 4, the driving link 20 is provided with a first limit slider 25 moving along a herringbone track. When the first limit slide block 25 of the driving connecting rod 20 slides along the straight line section of the herringbone track, the air deflector 50 is driven by the driving connecting rod 20 and the driven connecting rod 30 to do linear extending movement, when the first limit slide block 25 slides along the lower branch section 42 of the herringbone track, the first rotating shaft 11 of the crank slides along the first upper arc section 21, and when the first rotating shaft 11 of the crank slides to the communicating position of the first upper arc section 21 and the first lower arc section 22, the electromagnetic element 44 is controlled to be electrified, so that the first rotating shaft 11 continuously slides along the first lower arc section 22, and the air deflector 50 is opened upwards; when the first limiting slide block 25 slides along the upper branch section 41 of the herringbone track, the first rotating shaft 11 of the crank slides along the second upper arc section 23, and when the first rotating shaft 11 of the crank slides to the communication position of the second upper arc section 23 and the second lower arc section 24, the electromagnetic element is controlled to be electrified, so that the first rotating shaft 11 continues to slide along the second lower arc section 24, and the air deflector 50 is opened downwards.

As shown in fig. 8, in the driving mechanism provided in the embodiment of the present disclosure, the electromagnetic element 44 is disposed at the junction of the upper branch section 41 and the lower branch section 42 of the herringbone track, so that the driving link 20 sliding along the first upper arc section 21 can be attracted, so that the first rotation axis 11 of the crank continues to slide along the first lower arc section 22, the uniformity of the rotation angular velocity when the air deflector 50 is opened upwards is improved, and the driving link 20 sliding along the second upper arc section 23 can be attracted, so that the first rotation axis 11 of the crank continues to slide along the second lower arc section 24, and the uniformity of the rotation angular velocity when the air deflector 50 is opened downwards is improved.

Optionally, the track plate comprises a first plate surface provided with the herringbone track and a second plate surface opposite to the first plate surface. The electromagnetic element is arranged on the first plate surface, or the electromagnetic element is arranged on the second plate surface, or the electromagnetic element is embedded in the track plate.

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 25 includes an iron slide core, which is an attracting element.

The electromagnet attracts the iron slide core in the first limit slide block 25 in the electrified state, so that the first limit slide block 25 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 25 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 25 along the herringbone track.

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 25 sliding along the herringbone track, wherein the first limit sliding block 25 slides along the upper branch section 41, so that the air deflector 50 is opened downwards; the first limit slider 25 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 25 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 25 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 25 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 drive link 20 further includes a second limit slide 26 that slides along a linear track 43. The first limit slide 25 and the second limit slide 26 together define the movement of the drive link 20.

Optionally, the driven link 30 is provided with a through slot penetrating the driven link 30, through which the second limit slider 26 of the driving link 20 can penetrate 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 a rectilinear 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.

The manner in which the driving mechanism for the air deflector 50 drives the air deflector 50 to move is as follows:

the initial state of the drive mechanism in the closed state of the deflector 50 is shown in fig. 1. When the crank 10 rotates in the first direction or the second direction from the initial position shown in fig. 1, the first rotation shaft 11 slides in the sliding groove of the driving link 20 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 on the track plate, and the driven link 30 moves linearly along the straight line track on the track plate, so as to drive the air deflector 50 to move linearly to the first preset position. The first preset position may be understood as a position of the wind deflector 50 corresponding to the movement of the first limit slider 25 of the driving link 20 to the end of the straight line segment. In the embodiment of the disclosure, the first direction is clockwise, and the second direction is counterclockwise.

When the crank 10 rotates in the first direction, and when the air deflector 50 reaches the first preset position, the second rotating shaft 26 of the crank 10 moves to the first limiting point a, as shown in fig. 6, because there is an abutment force between the second rotating shaft 26 and the first limiting point a, the first limiting slider 25 of the driving link 20 is further provided with a driving force for selecting a track, so that the first limiting slider 25 of the driving link 20 enters the lower branch section 42 from a straight line section of the herringbone track, the second limiting slider 26 of the driving link 20 continues to move in the straight line track 43 through the through slot of the driven link 30, and the movement of the driving link 20 is redirected. At the same time, the driven link 30 continues to move linearly along the linear rail 43, so that the wind deflector 50 is opened upward under the combined drive of the driving link 20 and the driven link 30, as shown in fig. 10.

When the crank 10 rotates in the second direction, and when the air deflector 50 reaches the first preset position, the second rotating shaft 13 of the crank 10 moves to the second limiting point B, as shown in fig. 6, because there is an abutment force between the second rotating shaft 13 and the second limiting point B, the driving force for selecting the track is further provided for the first limiting slider 25 of the driving link 20, so that the first limiting slider 25 of the driving link 20 enters the upper branch section 41 from the straight line section of the herringbone track, the second limiting slider 26 of the driving link 20 continues to move in the straight line track 43 through the through slot of the driven link 30, and the movement of the driving link 20 is redirected. At the same time, the driven link 30 continues to move linearly along the linear rail 43, so that the wind deflector 50 is opened downward by the combined driving of the driving link 20 and the driven link 30, as shown in fig. 11.
