DETAILED DESCRIPTION

[0042] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0043] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046] like Figures 1 to 6 The present invention provides a variable-axis driven wind guide plate assembly, comprising: a first wind guide plate 1, a second wind guide plate 2 and a driving assembly 30; the driving assembly 30 comprises a first rotating shaft 301, a second rotating shaft 302 and a linkage mechanism; the first wind guide plate 1 is synchronously connected to the first rotating shaft 301, the second wind guide plate 2 is synchronously connected to the second rotating shaft 302, and the first rotating shaft 301 can rotate around the second rotating shaft 302; the linkage mechanism is used to guide the first rotating shaft 301 and / or the second rotating shaft 302 to rotate.

[0047] On the basis of the above structure, when the variable-axis driven air guide plate assembly of this embodiment is used, this embodiment takes the application of the air guide plate assembly to the air outlet of the air conditioner as an example, and the air guide plate assembly can be used to open or close the air outlet of the air conditioner.

[0048] In this embodiment, the driving component 30 includes a first rotating shaft 301, a second rotating shaft 302 and a linkage mechanism. The first air guide plate 1 is synchronously connected to the first rotating shaft 301, and the second air guide plate 2 is synchronously connected to the second rotating shaft 302. Moreover, the first rotating shaft 301 can rotate around the second rotating shaft 302, that is, when the first rotating shaft 301 rotates, it can drive the first air guide plate 1 to rotate. When the second rotating shaft 302 rotates, the first rotating shaft 301 can drive the first air guide plate 1 to rotate around the second rotating shaft 302, and the second air guide plate 2 will also rotate with the rotation of the second rotating shaft 302. The linkage mechanism is used to guide the first rotating shaft 301 to rotate, or to guide the second rotating shaft 302 to rotate so that the first rotating shaft 301 rotates around the second rotating shaft 302, and the second air guide plate 2 rotates, or the linkage mechanism can also be used to guide the first rotating shaft 301 and the second rotating shaft 302 to rotate at the same time, so that the first air guide plate 1 and the second air guide plate 2 can rotate at the same time.

[0049] Specifically, when the driving component 30 starts to start, the linkage mechanism first drives the first rotating shaft 301 to rotate, and the rotation of the first rotating shaft 301 drives the first air guide plate 1 to rotate, while the second rotating shaft 302 and the second air guide plate 2 do not rotate; when the linkage mechanism drives the first rotating shaft 301 to rotate to the first position, the linkage mechanism will also drive the second rotating shaft 302 to start rotating. At this time, the first rotating shaft 301 will start to rotate around the second rotating shaft 302, that is, the first air guide plate 1 will also start to rotate around the second rotating shaft 302 as the first rotating shaft 301 rotates, and at this time the second air guide plate 2 will also rotate as the second rotating shaft 302 rotates.

[0050] In the present embodiment, the first position is the position after the first air guide plate 1 is rotated to 90°. At this position, the first air guide plate 1 and the second air guide plate 2 are in a plane. At this time, the first air guide plate 1 and the second air guide plate 2 are extension plates of each other, which extend the air outlet channel. When the air conditioner is blowing, the air-conditioned air can be blown farther along the longer air outlet channel, so that the air-conditioned air can be effectively delivered to various parts of the space, making the indoor ambient temperature change more obvious. At the same time, the wind blown out from the air outlet channel is not blown directly to the human body, which can achieve a better air supply effect.

[0051] Example 1, a first specific implementation of the drive assembly 30 and the linkage mechanism:

[0052] Furthermore, if Figure 2 and Figure 3 As shown, the linkage mechanism includes a first transmission tooth 33 and a second transmission tooth 34, and the driving component 30 includes a first output tooth 31 and a second output tooth 32; the first output tooth 31 is arranged on the first rotating shaft 301, and the first output tooth 31 is synchronously connected with the first air guide plate 1; the second output tooth 32 is arranged on the second rotating shaft 302, and the second output tooth 32 is synchronously connected with the second air guide plate 2; the first transmission tooth 33 is arranged on the second rotating shaft 302, and the first transmission tooth 33 includes a first transmission section 331 and a second transmission section 332, and the first transmission section 331 is meshedly connected with the first output tooth 31; the second transmission tooth 34 includes a third transmission section 341 and a fourth transmission section 342, the third transmission section 341 is meshedly connected with the second transmission section 332, and the fourth transmission section 342 is rollingly connected or meshedly connected with the second output tooth 32 with missing teeth.

[0053] On the basis of the above structure, when the variable-axis driven air guide plate assembly of this embodiment is used, this embodiment takes the application of the air guide plate assembly to the air outlet of the air conditioner as an example, and the air guide plate assembly can be used to open or close the air outlet of the air conditioner.

[0054] According to the principle of air cooling and heating cycles, cold air is denser than air at normal temperature. When cooling, the air should blow upwards, and the cold air sinks, thereby cooling the entire room. The density of hot air is smaller than the air at normal temperature. When heating, the air should blow downwards, and the hot air rises, thereby heating up the entire room.

[0055] Therefore, in the present embodiment, in order to enable the air conditioner to better realize the functions of cooling and heating, the air conditioner host 4 is provided with a first air outlet and a second air outlet, the first air outlet is used to guide the airflow to be discharged along the first direction; the second air outlet is used to guide the airflow to be discharged along the second direction; the first direction and the second direction are arranged at an angle, specifically, in the present embodiment, the first direction is a horizontal direction, and the second direction is a vertical direction.

[0056] In this embodiment, specifically, the first air guide plate 1 and the second air guide plate 2 can realize four states.

[0057] Initial state: the first air guide plate 1 and the second air guide plate 2 are both in a position of closing the two air outlets.

[0058] The first use state: when the air is discharged horizontally, at this time, the first air guide plate 1 needs to be opened relative to the air outlet, and the second air guide plate 2 needs to be closed, that is, kept in a non-rotating state.

[0059] In this usage state, starting from the initial state, the second transmission tooth 34 starts to rotate, and at this time, the third transmission segment 341 of the second transmission tooth 34 starts to mesh with the second transmission segment 332 of the first transmission tooth 33, so the rotation of the second transmission tooth 34 will drive the first transmission tooth 33 to rotate, and since the first transmission segment 331 is meshed with the first output tooth 31, the rotation of the first transmission tooth 33 will also drive the first output tooth 31 to rotate, thereby rotating the first air guide plate 1; and the fourth transmission segment 342 of the second transmission tooth 34 is rollingly connected with the second output tooth 32 with missing teeth, and at this time, the rotation of the second transmission tooth 34 will not drive the second output tooth 32 to rotate, so the second air guide plate 2 does not rotate, that is, in this state, the first air guide plate 1 rotates, and the second air guide plate 2 does not rotate.

[0060] Second use state: when the air is discharged at an angle, the first air guide plate 1 and the second air guide plate 2 need to rotate at the same time.

[0061] In this usage state, starting from the first usage state, the second transmission tooth 34 continues to rotate. When the second transmission tooth 34 rotates to the first position, the fourth transmission section 342 of the second transmission tooth 34 also begins to mesh with the second output tooth 32. At this time, the second transmission tooth 34 is meshed with both the first transmission tooth 33 and the second output tooth 32. When the second transmission tooth 34 continues to rotate, the first transmission tooth 33 and the second output tooth 32 rotate at the same time, so the first output tooth 31 also rotates therewith. Therefore, in this state, the first air guide plate 1 and the second air guide plate 2 rotate at the same time.

[0062] The third use state: when the air is discharged vertically, the first air guide plate 1 and the second air guide plate 2 need to be rotated to the vertical position at the same time.

[0063] In this usage state, starting from the second usage state, the second transmission tooth 34 continues to rotate and drives the first transmission tooth 33 and the second output tooth 32 to rotate, and the first output tooth 31 also rotates accordingly, and the first air guide plate 1 and the second air guide plate 2 rotate to a vertical position at the same time, and close the first air outlet, so that the conditioned air is discharged from the second air outlet.

[0064] The first air guide plate 1 can serve as an extension plate of the second air guide plate 2, which is equivalent to extending the length of the horizontal air outlet channel. For the air-conditioning indoor unit, the longer horizontal air outlet channel can make the air-conditioning wind blow farther and cover a larger indoor space, thereby making the indoor ambient temperature change more obvious, effectively improving the efficiency of the air-conditioning in regulating the indoor temperature and improving the user experience.

[0065] It should be noted that the first air guide plate 1 and the second air guide plate 2 do not necessarily have to be perpendicular to each other, and the center angles of the first toothless segment 343 and the second toothless segment 381 do not necessarily need to be set to 90°, that is, the first air guide plate 1 and the second air guide plate 2 do not necessarily form a plane in the third use state. The center angle of the first toothless segment 343 can also be set to other degrees, so that an angle can be formed between the first air guide plate 1 and the second air guide plate 2 in the third use state. At this time, the first air guide plate 1 or the second air guide plate 2 can act as a windshield to prevent the air conditioning wind from blowing directly toward the human body, thereby achieving a better air supply effect. The angle of the center angle of the first toothless segment 343 can be set according to the needs of the actual situation.

[0066] Of course, in other cases, the variable-axis driven double wind guide plate can also be used in fans as long as air outlet in two directions is required, or other air outlet devices in the prior art can also apply the double-directional wind guide plate. The double wind guide plate can be applied and set according to actual needs.

[0067] Furthermore, a first meshing tooth segment and a first tooth-missing segment 343 are provided in the rotation direction of the fourth transmission segment 342 ; the first tooth-missing segment 343 is rollingly connected with the second output teeth 32 , and the first meshing tooth segment is meshingly connected with the second output teeth 32 .

[0068] On the basis of the above structure, the second transmission tooth 34 includes a third transmission section 341 and a fourth transmission section 342. The third transmission section 341 is all meshing tooth sections, and on the fourth transmission section 342, the first meshing tooth section and the first tooth-missing section 343 are distributed in the rotation direction of the fourth transmission section 342. The meshing tooth section of the third transmission section 341 is always meshed and connected with the first transmission tooth 33, and the first tooth-missing section 343 on the fourth transmission section 342 is rollingly connected with the second output tooth 32, and the first meshing tooth section is meshed and connected with the second output tooth 32.

[0069] In the initial state and the first use state, the first toothless section 343 on the fourth transmission section 342 is rollingly connected with the toothless section of the second output tooth 32. Therefore, in the first use state, the second transmission tooth 34 rotates, and the second output tooth 32 does not rotate therewith, while the first transmission tooth 33 rotates and drives the first output tooth 31 to rotate, that is, the first air guide plate 1 rotates, and the second air guide plate 2 does not rotate.

[0070] In the second use state and the third use state, the first meshing tooth segment on the fourth transmission segment 342 is meshed and connected with the second output tooth 32. In these two use states, the second transmission tooth 34 rotates, and the first transmission tooth 33 and the second output tooth 32 also rotate accordingly, and drive the first output tooth 31 to rotate, that is, the first air guide plate 1 and the second air guide plate 2 rotate at the same time.

[0071] By respectively arranging the third transmission section 341 and the fourth transmission section 342 on the axial left and right sides of the second transmission tooth 34, corresponding to the first transmission tooth 33 and the second output tooth 32 on the second rotating shaft 302, the first air guide plate 1 and the second air guide plate 2 can be switched between the first use state, the second use state and the third use state.

[0072] Compared with the prior art that requires two driving mechanisms to drive the first air guide plate 1 and the second air guide plate 2 respectively to realize the rotation of the first air guide plate 1 and the second air guide plate 2, the present embodiment only uses one driving mechanism to convert the first air guide plate 1 and the second air guide plate 2 between the first use state, the second use state and the third use state, which is more convenient and reduces the cost, and can also effectively reduce the space occupied by the driving component 30 in the air-conditioning host 4, and can effectively reduce the volume of the air-conditioning host 4, making the air conditioner more concise and beautiful.

[0073] This assembly method can also realize the transformation of the first air guide plate 1 and the second air guide plate 2 between the first use state, the second use state and the third use state, but because the rotation axes of the first air guide plate 1 and the second air guide plate 2 are different, the first air guide plate 1 and the second air guide plate 2 will move up and down relative to each other during the rotation process, so that there will be an assembly gap during the rotation, which may cause air leakage, resulting in energy loss and reducing the working efficiency of the air conditioner. Of course, it can be selected and set according to the actual needs.

[0074] In addition, in this embodiment, the third transmission section 341 and the fourth transmission section 342 of the second transmission tooth 34 are an integrated structure. Of course, the third transmission section 341 and the fourth transmission section 342 can also be fastened and connected by fasteners, such as bolt connection, welding or bonding, which can be selected and set according to actual needs.

[0075] Furthermore, if Figure 3 As shown, a circular arc guide surface is provided on the fourth transmission segment 342 , and the circular arc guide surface extends along the circumference of the fourth transmission segment 342 and forms a first toothless segment 343 .

[0076] On the basis of the above structure, an arc guide surface is provided on the fourth transmission segment 342 , and the arc guide surface forms the first tooth-missing segment 343 .

[0077] In the first usage state, when the second transmission tooth 34 rotates, the second output tooth 32 slides on the arc guide surface, that is, the rotation of the second transmission tooth 34 will not drive the second output tooth 32 to rotate, and because the second output tooth 32 is in contact with the arc guide surface, the second output tooth 32 is prevented from rotating due to the weight of the second air guide plate 2 itself or the force of external factors, thereby ensuring that the second air guide plate 2 does not rotate in the first usage state.

[0078] In the second and third use states, when the second transmission tooth 34 rotates, the second output tooth 32 is meshed and connected with the fourth transmission section 342 of the second transmission tooth 34. When the second transmission tooth 34 rotates, the second output tooth 32 also rotates, so that the second air guide plate 2 also rotates.

[0079] Furthermore, the first meshing tooth segments on both sides of the arc guide surface in the rotation direction form limiting teeth, and the second output tooth 32 is provided with positioning teeth, and the positioning teeth are provided with tooth tops that fit the arc guide surface, and the positioning teeth are in abutment with the limiting teeth.

[0080] On the basis of the above structure, in the initial state, when the tooth top of the positioning tooth on the second output tooth 32 fits with the arc guide surface, during the rotation of the second transmission tooth 34, the positioning tooth will not rotate with the rotation of the arc guide surface, and will abut and cooperate with the limiting tooth to prevent the second output tooth 32 from rotating due to the gravity of the second air guide plate 2 itself after assembly or in the initial state, so as to achieve stable assembly.

[0081] Example 2, a second specific implementation of the drive assembly 30 and the linkage mechanism:

[0082] Furthermore, if Figure 4 and Figure 5 As shown, the linkage mechanism includes a third transmission tooth 37 and a fourth transmission tooth 38, and the drive assembly 30 includes a third output tooth 35 and a fourth output tooth 36; the third output tooth 35 is arranged on the first rotating shaft 301, and the third output tooth 35 is synchronously connected with the first air guide plate 1; the fourth output tooth 36 is arranged on the second rotating shaft 302, and the fourth output tooth 36 is synchronously connected with the second air guide plate 2; the third transmission tooth 37 is arranged on the second rotating shaft 302, and the third transmission tooth 37 includes a fifth transmission section 371 and a sixth transmission section 372, and the fifth transmission section 371 is meshedly connected with the third output tooth 35; the fourth transmission tooth 38 is provided with a seventh transmission section and an eighth transmission section, and the seventh transmission section is rollingly connected or meshedly connected with the sixth transmission section 372 by missing teeth, and the eighth transmission section is rollingly connected or meshedly connected with the fourth output tooth 36 by missing teeth.

[0083] On the basis of the above structure, in this embodiment, the linkage mechanism adopts another structure to drive the first rotating shaft 301 and the second rotating shaft 302 to rotate, so that the first air guide plate 1 and the second air guide plate 2 switch modes and rotate.

[0084] In this embodiment, specifically, the first air guide plate 1 and the second air guide plate 2 can also realize four states.

[0085] Initial state: the first air guide plate 1 and the second air guide plate 2 are both in a position to close the two air outlets.

[0086] The first use state: when the air is discharged horizontally, at this time, the first air guide plate 1 needs to be opened relative to the air outlet, and the second air guide plate 2 needs to be closed, that is, kept in a non-rotating state.

[0087] In this usage state, starting from the initial state, when the fourth transmission tooth 38 starts to rotate, the meshing tooth segment of the seventh transmission section of the fourth transmission tooth 38 is meshed and transmission-connected with the sixth transmission section 372 of the third transmission tooth 37, and the eighth transmission section of the fourth transmission tooth 38 is rollingly connected with the fourth output tooth 36. Therefore, when the fourth transmission tooth 38 rotates, it can drive the third transmission tooth 37 to rotate, while the fourth output tooth 36 does not rotate. Since the third transmission tooth 37 rotates, the third output tooth 35 is also driven to rotate. That is, in this state, the first air guide plate 1 rotates, while the second air guide plate 2 does not rotate, and the first air guide plate 1 is rotated to a horizontal position and is in the same plane with the second air guide plate 2.

[0088] Second use state: when the air is discharged at an angle, the second air guide plate 2 needs to start rotating as well.

[0089] In this usage state, starting from the first usage state, the fourth transmission tooth 38 continues to rotate, and the meshing tooth segment of the eighth transmission section of the fourth transmission tooth 38 begins to mesh with the fourth output tooth 36 for transmission connection, and the seventh transmission section of the fourth transmission tooth 38 begins to be rollingly connected with the sixth transmission section 372 of the third transmission tooth 37 with missing teeth. Then, when the fourth transmission tooth 38 rotates, it can drive the fourth output tooth 36 to rotate, and the third transmission tooth 37 does not rotate therewith. That is, in this state, the second air guide plate 2 rotates, and the first air guide plate 1 does not rotate, and the second air guide plate 2 rotates to a certain angle, and the first air guide plate 1 remains horizontal.

[0090] The third use state: when the air is discharged vertically, the second air guide plate 2 is rotated to a vertical position, while the first air guide plate 1 remains horizontal.

[0091] In this usage state, starting from the second usage state, the fourth transmission tooth 38 continues to rotate, the seventh transmission segment on the fourth transmission tooth 38 is still rollingly connected with the sixth transmission segment 372 with missing teeth, and the eighth transmission segment continues to be meshed and connected with the fourth output tooth 36. Then, as the fourth transmission tooth 38 rotates, the fourth output tooth 36 will also rotate accordingly, while the third transmission tooth 37 does not rotate accordingly. That is, at this time, the first air guide plate 1 does not rotate and maintains a horizontal position, and the second air guide plate 2 rotates to a vertical position.

[0092] The first air guide plate 1 can serve as an extension plate of the second air guide plate 2, which is equivalent to extending the length of the horizontal air outlet channel. For the air-conditioning indoor unit, the longer horizontal air outlet channel can make the air-conditioning wind blow farther and cover a larger indoor space, thereby making the indoor ambient temperature change more obvious, effectively improving the efficiency of the air-conditioning in regulating the indoor temperature and improving the user experience.

[0093] Furthermore, if Figure 5As shown, the seventh transmission section is provided with a third meshing tooth section and a second toothless section 381 in the rotation direction; the eighth transmission section is provided with a fourth meshing tooth section and a third toothless section 382 in the rotation direction; the second toothless section 381 and the third toothless section 382 are staggered in the axial projection of the fourth transmission tooth 38; when the second toothless section 381 and the sixth transmission section 372 are rollingly matched, the fourth meshing tooth section is meshed with the fourth output tooth 36; when the third toothless section 382 and the fourth output tooth 36 are rollingly matched, the third meshing tooth section is meshed with the sixth transmission section 372.

[0094] On the basis of the above structure, the fourth transmission tooth 38 includes a seventh transmission section and an eighth transmission section, and a third meshing tooth section and a second tooth-missing section 381 are provided in the rotation direction of the seventh transmission section. On the eighth transmission section, the fourth meshing tooth section and the third tooth-missing section 382 are distributed in the rotation direction of the eighth transmission section, and the second tooth-missing section 381 and the third tooth-missing section 382 are staggered in the axial projection of the fourth transmission tooth 38, that is, when the third meshing tooth section of the seventh transmission section is meshed and connected with the sixth transmission section 372, the third tooth-missing section 382 of the eighth transmission section is rollingly connected with the fourth output tooth 36; and when the second tooth-missing section 381 of the seventh transmission section is rollingly connected with the sixth transmission section 372, the fourth meshing tooth section of the eighth transmission section is meshed and connected with the fourth output tooth 36.

[0095] In the initial state and the first use state, the third meshing tooth segment on the seventh transmission segment is meshed and connected with the sixth transmission segment 372, and the third toothless segment 382 on the eighth transmission segment is rollingly connected with the fourth output tooth 36. Therefore, in the first use state, the fourth transmission tooth 38 rotates, and the fourth output tooth 36 does not rotate therewith, while the third transmission tooth 37 rotates and drives the third output tooth 35 to rotate, that is, the first air guide plate 1 rotates, and the second air guide plate 2 does not rotate.

[0096] In the second and third use states, the second toothless segment 381 on the seventh transmission segment is rollingly connected to the sixth transmission segment 372, and the fourth meshing tooth segment on the eighth transmission segment is meshingly connected to the fourth output tooth 36. In these two use states, the fourth transmission tooth 38 rotates, and the fourth output tooth 36 also rotates, while the third transmission tooth 37 does not rotate, that is, the first output tooth 31 does not rotate, that is, the first air guide plate 1 does not rotate, and the second air guide plate 2 rotates.

[0097] By respectively arranging the seventh transmission section and the eighth transmission section on the axial left and right sides of the fourth transmission tooth 38, corresponding to the third transmission tooth 37 and the fourth output tooth 36 on the second rotating shaft 302, the first air guide plate 1 and the second air guide plate 2 can be switched between the first use state, the second use state and the third use state.

[0098] Compared with the prior art that requires two driving mechanisms to drive the first air guide plate 1 and the second air guide plate 2 respectively to realize the rotation of the first air guide plate 1 and the second air guide plate 2, the present embodiment only uses one driving mechanism to convert the first air guide plate 1 and the second air guide plate 2 between the first use state, the second use state and the third use state, which is more convenient and reduces the cost, and can also effectively reduce the space occupied by the driving component 30 in the air-conditioning host 4, and can effectively reduce the volume of the air-conditioning host 4, making the air conditioner more concise and beautiful.

[0099] Example 3, a third specific implementation of the drive assembly 30 and the linkage mechanism:

[0100] Furthermore, the linkage mechanism includes a first traction part and a second traction part, the first traction part is arranged on the first rotating shaft 301, and the second traction part is arranged on the second rotating shaft 302, and the first traction part can be used to stagger or pull with the second traction part; when the first traction part and the second traction part are staggered, the first rotating shaft 301 rotates alone; when the first traction part and the second traction part are pulled together, the first rotating shaft 301 and the second rotating shaft 302 rotate simultaneously.

[0101] On the basis of the above structure, in this embodiment, specifically, the first air guide plate 1 and the second air guide plate 2 can realize four states.

[0102] Initial state: the first air guide plate 1 and the second air guide plate 2 are both in a position of closing the two air outlets.

[0103] The first use state: when the air is discharged horizontally, at this time, the first air guide plate 1 needs to be opened relative to the air outlet, and the second air guide plate 2 needs to be closed, that is, kept in a non-rotating state.

[0104] In this usage state, starting from the initial state, the first traction part and the second traction part are staggered. At this time, the linkage mechanism drives the first rotating shaft 301 to rotate alone, that is, the first rotating shaft 301 rotates and the second rotating shaft 302 does not rotate, so that the first air guide plate 1 rotates to a horizontal position, and the second air guide plate 2 does not rotate, and horizontal air is discharged.

[0105] Second use state: when the air is discharged at an angle, the first air guide plate 1 and the second air guide plate 2 need to rotate at the same time.

[0106] In this usage state, starting from the first usage state, when the linkage mechanism drives the first traction part on the first rotating shaft 301 to cooperate with the second traction part on the second rotating shaft 302, the linkage mechanism continues to drive the first rotating shaft 301 to rotate, and the rotation of the first rotating shaft 301 will also drive the second rotating shaft 302 to rotate, that is, the first air guide plate 1 and the second air guide plate 2 rotate at the same time, and angle air is discharged.

[0107] The third use state: when the air is discharged vertically, the first air guide plate 1 and the second air guide plate 2 need to be rotated to the vertical position at the same time.

[0108] In this usage state, starting from the second usage state, the linkage mechanism continues to drive the first rotating shaft 301 to rotate, and the first traction part at this time is still pulled and cooperated with the second traction part, and the first rotating shaft 301 and the second rotating shaft 302 continue to rotate at the same time, and the first air guide plate 1 and the second air guide plate 2 rotate at the same time, so that the first air guide plate 1 and the second air guide plate 2 are rotated to a vertical position and vertical air is discharged.

[0109] The first air guide plate 1 can serve as an extension plate of the second air guide plate 2, which is equivalent to extending the length of the horizontal air outlet channel. For the air-conditioning indoor unit, the longer horizontal air outlet channel can make the air-conditioning wind blow farther and cover a larger indoor space, thereby making the indoor ambient temperature change more obvious, effectively improving the efficiency of the air-conditioning in regulating the indoor temperature and improving the user experience.

[0110] Further, the first traction portion is a first abutting portion, and the second traction portion is a second abutting portion. After the first abutting portion rotates to abut against the second abutting portion, the first rotating shaft 301 and the second rotating shaft 302 rotate simultaneously.

[0111] On the basis of the above structure, in this embodiment, specifically, the first traction portion is a first abutting portion, and the second traction portion is a second abutting portion.

[0112] In the first use state, the first abutment portion and the second abutment portion are separated from each other. At this time, when the linkage mechanism drives the first rotating shaft 301, the first rotating shaft 301 rotates alone and drives the first air guide plate 1 to rotate, while the second rotating shaft 302 does not rotate, that is, the second air guide plate 2 does not rotate.

[0113] In the second and third usage states, the first abutment portion has rotated to begin to abut against the second abutment portion. At this time, when the linkage mechanism continues to drive the first rotating shaft 301 to rotate, the rotation of the first rotating shaft 301 will also drive the second rotating shaft 302 to rotate. Then, the first rotating shaft 301 and the first air guide plate 1 will also rotate around the second rotating shaft 302, and the second air guide plate 2 will also rotate accordingly. At this time, the first air guide plate 1 and the second air guide plate 2 rotate at the same time.

[0114] It should be noted that, in addition to the above three embodiments, other embodiments may be adopted to realize a linkage mechanism to guide the first rotating shaft 301 and / or the second rotating shaft 302 to rotate, including the use of multiple gears cooperating with each other, or the use of gears and connecting rods, or the use of spring pins and insertion holes, or other embodiments in the prior art, etc. It is only necessary to enable the linkage mechanism to guide the first rotating shaft 301 and / or the second rotating shaft 302 to rotate so as to realize the mutual switching of the first air guide plate 1 and the second air guide plate 2 between the initial state, the first use state, the second use state and the third use state, and it can be selected and set according to the needs of the actual situation.

[0117] Specifically, in this embodiment, in order to better achieve cooling or heating, the first direction is a horizontal direction, the second direction is a vertical direction, and the first direction and the second direction are perpendicular to each other.

[0118] On the basis of the above structure, taking air conditioning refrigeration as an example, when the air conditioner is in the off state, the first air guide plate 1 and the second air guide plate 2 are perpendicular to each other. At this time, the first air guide plate 1 closes the first air outlet, and the second air guide plate 2 closes the second air outlet.

[0119] When the air conditioner is started, the cooling or heating module in the air conditioner main unit 4 can perform cooling or heating, and the generated hot air or cold air can be discharged through the first air outlet or the second air outlet on the air conditioner main unit 4.

[0120] In this embodiment, specifically, the first air guide plate 1 and the second air guide plate 2 can realize four states.

[0121] Initial state: the first air guide plate 1 and the second air guide plate 2 are both in a position of closing the two air outlets.

[0122] The first use state: when the air is discharged horizontally, at this time, the first air guide plate 1 needs to be opened relative to the air outlet, and the second air guide plate 2 needs to be closed, that is, kept in a non-rotating state.

[0123] Second usage state: when the air is discharged at an angle, the first air guide plate 1 and the second air guide plate 2 need to be opened relative to the first air outlet and the second air outlet.

[0124] The third usage state: when the air is discharged vertically, the first air outlet needs to be closed and the second air outlet needs to be opened.

[0125] By adopting the above-mentioned variable-axis driven air guide plate assembly, the first air guide plate 1 and the second air guide plate 2 can be rotated individually or simultaneously to achieve switching between the above-mentioned usage states, so that the air conditioner can achieve different modes of air outlet to meet the needs of users.
