[0064] The term "and / or" is a description of the association between objects, which means that there can be three relationships. For example, A and / or B, which means: A or B, or, A and B, three relationships.

[0065] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0066] In combination Figures 1-30 As shown, the embodiments of the present disclosure provide a connecting rod.

[0067] The connecting rod is configured to be connected with the driven member to drive the driven member to move.

[0068] The connecting rod is fixedly connected or movably connected with the driven member, and when movably connected, can be rotatably connected or slidably connected.

[0069] The connecting rod can be in the form of a rack 7, which is connected with the driven member for driving the driven member to move. It can be understood that the connecting rod can also be a component without teeth, and the driven member can also be driven to move by the movement of the connecting rod. When the connecting rod is the rack 7, the disclosure also provides a gear 61 engaged with the rack 7. When the gear 61 and the rack 7 are applied to an air conditioner, the driven member can be a guide vane 2. It can be understood that the driven member can also be other components that need to have multiple target positions, especially components that need to be flipped. In this application, the driven member is taken as the guide vane 2 for illustration.

[0070] The air conditioner includes an indoor unit, which includes a shell 1, an indoor heat exchanger, and a fan. The shell 1 defines an air duct and is provided with an air inlet and an air outlet, both of which are in communication with the air duct.

[0071] The fan and the indoor heat exchanger are located in the air duct. Under the action of the fan, air enters the air duct through the air inlet, exchanges heat with the indoor heat exchanger, and is blown out from the air outlet.

[0072] The guide vane 2 is arranged at the air outlet and can move relative to the air outlet to realize multiple air guiding forms.

[0073] The driving device for the guide vane 2 of the air conditioner includes the above-mentioned gear 61 and rack 7.

[0074] The gear 61 is controlled to rotate.

[0075] As shown in Figure 5 and Figure 13 , the rack 7 is provided with a first tooth segment 711 and a second tooth segment 712 arranged in sequence along the length direction of the rack 7, both of which can be engaged with the gear 61, and the rack 7 is connected with the guide vane 2; wherein when the gear 61 is engaged with the first tooth segment 711, the gear 61 and the rack 7 are one of internally engaged and externally engaged; and when the gear 61 is engaged with the second tooth segment 712, the gear 61 and the rack 7 are the other one of internally engaged and externally engaged.

[0076] The gear 61 can be driven to rotate by a driving member 62, which can be a motor. The motor can directly drive the gear 61 to rotate, or can intermittently drive the gear 61 to rotate through other transmission members, which can be a driving gear 61 or a belt, etc.

[0077] The rack 7 is connected with the air deflector 2, which can be fixed connection, for example, one of the rack 7 and the air deflector 2 is provided with a connecting column, and the other is provided with a connecting hole, the connecting column and the connecting hole are matched, the connecting column is inserted into the connecting hole, the cross section of the connecting hole is non-circular, and the outer surface of the cross section of the connecting column is also non-circular, so as to avoid the rotation of the connecting column relative to the connecting hole, realize the fixation of the rack 7 and the air deflector 2, and thus the movement of the rack 7 can be accurately transmitted to the air deflector 2, so as to better control the movement of the air deflector 2; the rack 7 and the air deflector 2 can also be movably connected, for example, rotationally connected or slidably connected.

[0078] As shown in Figure 5 and Figure 13 , when the gear 61 is engaged with the first tooth segment 711, the gear 61 and the rack 7 are internally engaged; when the gear 61 is engaged with the second tooth segment 712, the gear 61 and the rack 7 are externally engaged. Alternatively, when the gear 61 is engaged with the first tooth segment 711, the gear 61 and the rack 7 are externally engaged; when the gear 61 is engaged with the second tooth segment 712, the gear 61 and the rack 7 are internally engaged.

[0079] In this way, the gear 61 and the rack 7 will switch between internal engagement and external engagement during engagement. Because the rotation center of the rack 7 will be different during internal engagement and external engagement, the rotation direction of the air deflector 2 will be different, which can drive the air deflector 2 to rotate in different directions, for example, the air deflector 2 can rotate clockwise and counterclockwise, thereby realizing the requirements of cooling upward blowing and heating downward blowing.

[0080] Because the rotation center of the rack 7 changes, the rotation direction of the air deflector 2 changes, so the rack 7 can drive the air deflector 2 to rotate in different directions, without the need to additionally provide other racks 7 or connecting rods, thereby greatly simplifying the structure of the driving device for the air deflector 2 of the air conditioner.

[0081] In other words, the number of the rack 7 is one, and no other connecting rod is connected to the air deflector 2.

[0082] During the opening process of the air deflector 2, the switching between internal engagement and external engagement of the gear 61 and the rack 7 is used to realize the turning of the air deflector 2, therefore, during the opening process of the air deflector 2, the motor rotates unidirectionally throughout the process, thereby simplifying the control of the motor.

[0083] Optionally, as shown in Figure 18 , the rack 7 is also provided with a third tooth segment 713, the third tooth segment 713 is a straight tooth segment, and the third tooth segment 713 can be engaged with the gear 61.

[0084] The third tooth segment 713 extends along the length of the rack 7 and is a straight tooth segment. When the gear 61 is engaged with the third tooth segment 713, the rack 7 is driven to move in a straight line, and the rack 7 drives the air deflector 2 to move in a straight line, thereby extending or retracting the air deflector 2.

[0085] The extension or retraction of the air guide plate 2 is coordinated with the rotation of the air guide plate 2 in different directions, thereby realizing various air guiding forms of the air guide plate 2.

[0086] Optionally, the first tooth segment 711, the second tooth segment 712 and the third tooth segment 713 are sequentially arranged along the length direction of the rack 7, and the gear 61 engages with the first tooth segment 711, the second tooth segment 712 and the third tooth segment 713 in sequence during the opening process of the air deflector 2.

[0087] During the opening process of the air guide plate 2, the gear 61 first meshes with the first tooth segment 711 to realize the rotation of the rack 7, thereby realizing the rotation of the air guide plate 2 along the first direction, realizing cooling upward or heating downward blowing. The following takes cooling upward as an example. Figures 10 to 14 As shown. The gear 61 then meshes with the second tooth segment 712, driving the air guide plate 2 to rotate in a second direction opposite to the first direction. The central angle corresponding to the first tooth segment 711 is greater than the central angle corresponding to the second tooth segment 712. Subsequently, the gear 61 meshes with the third tooth segment 713, and the rack 7 extends outward, driving the air guide plate 2 to extend outward, realizing a small encircling air supply, as shown. Figures 15 to 18 One of the first direction and the second direction is clockwise, and the other is counterclockwise.

[0088] Alternatively, as Figure 20 As shown, the rack 7 is further provided with a fourth tooth segment 714, and the first tooth segment 711, the second tooth segment 712, the third tooth segment 713 and the fourth tooth segment 714 are arranged in sequence along the length direction of the rack 7, and the fourth tooth segment 714 can engage with the gear 61, and when the fourth tooth segment 714 engages with the gear 61, the gear 61 and the rack 7 are the other of the internal engagement and the external engagement. In other words, when the gear 61 engages with the fourth tooth segment 714, the air guide plate 2 rotates along the second direction.

[0089] like Figure 12 As shown, the air outlet includes a first air outlet area 111 and a second air outlet area 112. The indoor unit also includes a guide plate 3. The first and second air outlet areas 111 and 112 are arranged sequentially along the width of the air outlet. The guide plate 2 is provided in the first air outlet area 111 and is used to open or close the first air outlet area 111 and adjust the airflow direction of the first air outlet area 111. The guide plate 3 is provided in the second air outlet area 112 and is used to open or close the second air outlet area 112 and adjust the airflow direction of the second air outlet area 112.

[0090] Taking the air conditioner as an example, the first air outlet area 111 and the second air outlet area 112 are arranged in sequence along the up-down direction. As shown in Figure 12 , the first air outlet area 111 is located below the second air outlet area 112. It can be understood that the first air outlet area 111 can also be located above the second air outlet area 112.

[0091] As shown in Figures 19 to 22 , when the gear 61 engages with the fourth tooth segment 714, the air deflector 2 rotates in the second direction, at this time the guide plate 3 rotates towards the direction of the air deflector 2, the guide plate 3 abuts against the guide plate, realizing large ring embrace air supply, wherein under the same conditions, the air supply amount of large ring embrace air supply is greater than that of small ring embrace air supply.

[0092] Optionally, the central angle corresponding to the fourth tooth segment 714 is greater than the central angle corresponding to the second tooth segment 712.

[0093] In this way, when the gear 61 engages with the fourth tooth segment 714, it can drive the air deflector 2 to rotate a larger angle, and the rotation angle is greater than that driven by the gear 61 engaging with the second tooth segment 712. The large-angle rotation of the air deflector 2 drives the air deflector 2 to move to the heating lower blowing position, realizing heating lower blowing.

[0094] The central angle corresponding to the fourth tooth segment 714 is the central angle corresponding to the fourth tooth segment 714; the central angle corresponding to the second tooth segment 712 is the central angle corresponding to the second tooth segment 712.

[0095] Optionally, as shown in Figure 23 , the rack 7 is also provided with a fifth tooth segment 715, and the first tooth segment 711 to the fifth tooth segment 715 are arranged in sequence, that is, the first tooth segment 711, the second tooth segment 712, the third tooth segment 713, the fourth tooth segment 714 and the fifth tooth segment 715 are arranged in sequence, and the fifth tooth segment 715 is a straight tooth segment.

[0096] The fifth tooth segment 715 extends along the length direction of the rack 7 and is a straight tooth segment. In this way, when the gear 61 engages with the fifth tooth segment 715, it drives the rack 7 to move in a straight line direction, and the rack 7 drives the air deflector 2 to move in a straight line direction, realizing the outward extension or retraction of the air deflector 2.

[0097] After the air deflector 2 moves from the heating lower blowing position, it extends in a straight line direction to cooperate with the rotation of the air deflector 2 in different directions, thereby realizing various air deflection forms of the air deflector 2.

[0098] Optionally, as shown in Figure 26As shown, the rack 7 is further provided with a sixth tooth segment 716, and the first tooth segment 711 to the sixth tooth segment 716 are sequentially arranged, i.e., the first tooth segment 711, the second tooth segment 712, the third tooth segment 713, the fourth tooth segment 714, the fifth tooth segment 715 and the sixth tooth segment 716 are sequentially arranged, the sixth tooth segment 716 is capable of engaging with the gear 61, and when the sixth tooth segment 716 engages with the gear 61, the gear 61 and the rack 7 are the other one of the internal engagement and the external engagement.

[0099] When the sixth tooth segment 716 engages with the gear 61, the rack 7 drives the air deflector 2 to rotate in the second direction to reach the maximum air supply position, and at this time, the air supply amount can reach the maximum.

[0100] Optionally, the central angle corresponding to the sixth tooth segment 716 is greater than the central angle corresponding to the second tooth segment 712.

[0101] In this way, when the gear 61 engages with the sixth tooth segment 716, it can drive the air deflector 2 to rotate a large angle, and the rotation angle is greater than the rotation angle of the air deflector 2 driven by the gear 61 engaging with the second tooth segment 712. The large-angle rotation of the air deflector 2 drives the air deflector 2 to move to the maximum air supply position, thereby realizing maximum air supply.

[0102] The central angle corresponding to the sixth tooth segment 716 is the central angle corresponding to the sixth tooth segment 716.

[0103] The central angles and radii corresponding to the first tooth segment 711, the second tooth segment 712, the fourth tooth segment 714 and the sixth tooth segment 716, the lengths of the third tooth segment 713 and the fifth tooth segment 715, and the air deflector positions of the air deflector 2 are related to each other, and in actual application, they need to be determined according to the specific positions of the air deflector 2.

[0104] In a specific embodiment, the first tooth segment 711, the second tooth segment 712, the fourth tooth segment 714 and the sixth tooth segment 716 are all circular arcs, the central angle of the first tooth segment 711 is 12°, the central angle of the second tooth segment 712 is 18°, the central angle of the fourth tooth segment 714 is 67°, the central angle of the sixth tooth segment 716 is 32°, the length of the third tooth segment 713 is greater than the length of the fifth tooth segment 715, the length of the third tooth segment 713 is 20 mm, and the length of the fifth tooth segment 715 is 18.6 mm.

[0105] The radius of the circle on which the first tooth section 711 is located, the radius of the circle on which the second tooth section 712 is located, the radius of the circle on which the fourth tooth section 714 is located, and the radius of the circle on which the sixth tooth section 716 is located increase in turn. In this way, when the gear 61 is engaged with the first tooth section 711, the movement speed of the rack 7, when the gear 61 is engaged with the second tooth section 712, the movement speed of the rack 7, when the gear 61 is engaged with the fourth tooth section 714, the movement speed of the rack 7, and when the gear 61 is engaged with the sixth tooth section 716, the movement speed of the rack 7 decrease in turn, and the movement speed of the air deflector 2 decreases correspondingly. Since the length of the rack 7 extending out of the air outlet is large at the later stage of the opening of the air deflector 2, and the air deflector 2 has already completely left the air outlet, the design that the movement speed of the rack 7 decreases and the movement of the air deflector 2 slows down as the air deflector 2 opens can make the movement of the rack 7 and the air deflector 2 more stable, and avoid the rack 7 from shaking and driving the air deflector 2 to shake.

[0106] As shown in Figure 23 , the gear 61 is located on one side of the rack 7, and the rack 7 is connected to the driven member.

[0107] As shown in Figure 31 , the pitch curve of the rack 7 includes at least two of the first arc section A1A2, the second arc section A2A3, and the first straight line section A4A5, wherein one of the curvature center O1 of the first arc section A1A2 and the curvature center O2 of the second arc section A2A3 is located on the side of the rack 7 facing the gear 61, and the other is located on the side of the rack 7 away from the gear 61.

[0108] When the curvature center O1 of the first arc section A1A2 is located on the side of the rack 7 facing the gear 61, the curvature center O2 of the second arc section A2A3 is located on the side of the rack 7 away from the gear 61; when the curvature center of the first arc section A1A2 is located on the side of the rack 7 away from the gear 61, the curvature center of the second arc section A2A3 is located on the side of the rack 7 facing the gear 61. In this way, the rotation direction of the rack 7 when the gear 61 is engaged with the teeth corresponding to the first arc section A1A2 on the rack 7 and the rotation direction of the rack 7 when the gear 61 is engaged with the teeth corresponding to the second arc section A2A3 on the rack 7 are different.

[0109] As shown in Figure 31As shown, when the pitch curve of the rack 7 includes a first arc segment A1A2 and a second arc segment A2A3, the rotation direction of the rack 7 when the gear 61 is engaged with the teeth corresponding to the first arc segment A1A2 on the rack 7 is different from the rotation direction of the rack 7 when the gear 61 is engaged with the gear teeth corresponding to the second arc segment A2A3 on the rack 7, resulting in different rotation directions of the air deflector 2. As a result, the rack 7 can drive the air deflector 2 to rotate in different directions without the need for an additional connecting rod to cooperate with the rack 7 to achieve the rotation of the air deflector 2 in different directions. On the one hand, the structure of the rack 7 is simplified. On the other hand, the position of the air deflector 2 is controlled by the rack 7 without the need for an additional connecting rod, which prevents the connecting rod from affecting the position of the air deflector 2 and reduces the factors affecting the position of the air deflector 2, thereby improving the position accuracy of the air deflector 2.

[0110] When the pitch curve of the rack 7 includes a first arc segment A1A2 and a first straight segment A4A5, when the gear 61 is engaged with the teeth corresponding to the first arc segment A1A2 on the rack 7, it can drive the rack 7 to rotate, thereby driving the air guide plate 2 to rotate. When the gear 61 is engaged with the teeth corresponding to the first straight segment A4A5 on the rack 7, it can drive the rack 7 to move in a straight line, thereby driving the air guide plate 2 to move in a straight line, thereby realizing various movement forms of the air guide plate 2, and then realizing various target positions of the air guide plate 2.

[0111] like Figure 31 As shown, when the pitch curve of the rack 7 includes a second arc segment A2A3 and a first straight segment A4A5, when the gear 61 is engaged with the teeth corresponding to the second arc segment A2A3 on the rack 7, it can drive the rack 7 to rotate, thereby driving the air guide plate 2 to rotate. When the gear 61 is engaged with the teeth corresponding to the first straight segment A4A5 on the rack 7, it can drive the rack 7 to move in a straight line, thereby driving the air guide plate 2 to move in a straight line, thereby realizing various movement forms of the air guide plate 2, and then realizing various target positions of the air guide plate 2.

[0112] like Figure 31 As shown, when the pitch curve of the rack 7 includes the first arc segment A1A2, the second arc segment A2A3 and the first straight segment A4A5, the target positions of the air guide plate 2 can be further increased, and the target positions can be greatly different from each other.

[0113] Optionally, the pitch curve of the rack 7 includes a first arc segment A1A2, a second arc segment A2A3 and a first straight segment A4A5, and the first arc segment A1A2, the second arc segment A2A3 and the first straight segment A4A5 are arranged in sequence along the length direction of the rack 7.

[0114] The teeth corresponding to the first arc segment A1A2 on the rack 7 are a first tooth segment 711, the teeth corresponding to the second arc segment A2A3 are a second tooth segment 712, and the teeth corresponding to the first straight line segment A4A5 are a third tooth segment 713.

[0115] During the opening process of the deflector 2, the gear 61 first engages with the first tooth segment 711 to realize the rotation of the rack 7, thereby realizing the rotation of the deflector 2 in the first direction and realizing the upward blowing of the refrigeration. The gear 61 then engages with the second tooth segment 712 to drive the deflector 2 to rotate in the second direction opposite to the first direction. Subsequently, the gear 61 engages with the third tooth segment 713, the rack 7 extends outward, and the deflector 2 extends outward, thereby realizing the small ring embrace air supply.

[0116] Alternatively, in the case that the pitch curve of the rack 7 includes the first arc segment A1A2 and the first straight line segment A4A5 connected thereto, the pitch curve of the rack 7 further includes a first transition segment, the first transition segment is connected between the first arc segment A1A2 and the first straight line segment A4A5, the first transition segment is arc-shaped, and the tangent line of the end of the first transition segment coincides with the first straight line segment A4A5.

[0117] In other words, the first arc segment A1A2, the first transition segment, and the first straight line segment A4A5 are sequentially arranged. The end of the first transition segment refers to one end of the first transition segment connected to the first straight line segment A4A5.

[0118] The tangent direction of the end of the first arc segment A1A2 (i.e., one end of the first arc segment A1A2 close to the first straight line segment A4A5) is not parallel to the first straight line segment A4A5. Therefore, the first transition segment is added to adjust the position of the tangent point of the gear 61 and the rack 7, so that the rack 7 can be switched to move in the direction of a straight line.

[0119] The first transition segment is a circular arc on the pitch curve of the gear 61.

[0120] Alternatively, in the case that the pitch curve of the rack 7 includes the second arc segment A2A3 and the first straight line segment A4A5 connected thereto, the pitch curve of the rack 7 further includes a second transition segment A3A4, the second transition segment A3A4 is connected between the second arc segment A2A3 and the first straight line segment A4A5, the second transition segment A3A4 is arc-shaped, and the tangent line of the end of the second transition segment A3A4 coincides with the first straight line segment A4A5.

[0121] In other words, the second arc segment A2A3, the first transition segment, and the first straight line segment A4A5 are sequentially arranged. The end of the first transition segment refers to one end of the first transition segment connected to the first straight line segment A4A5.

[0122] The tangent direction of the end of the second arc segment A2A3 (i.e., the end of the second arc segment A2A3 close to the first straight segment A4A5) is not parallel to the first straight segment A4A5. Therefore, a first transition segment is added to adjust the position of the tangent point between the gear 61 and the rack 7 so that the rack 7 can switch to moving in a straight line direction.

[0123] The first transition section is an arc on the pitch curve of gear 61.

[0124] Alternatively, as Figure 31 As shown, when the pitch curve of the rack 7 includes the first straight line segment A4A5, the pitch curve of the rack 7 also includes a third arc segment A6A7. The third arc segment A6A7 is connected to the end of the first straight line segment A4A5 away from the first arc segment A1A2 or the second arc segment A2A3, that is, the third arc segment A6A7 is connected to the end of the first straight line segment A4A5, and the center of curvature of the third arc segment A6A7 is located on the side of the rack 7 facing toward or away from the gear 61. Figure 31 As shown, the curvature center O3 of the third arc segment A6A7 is located on the side of the rack 7 facing the gear 61 . At this time, the tooth on the rack 7 corresponding to the third arc segment A6A7 is the fourth tooth segment 714 .

[0125] The arc segment is set so that when the gear 61 engages with the teeth corresponding to the third tooth segment 713 on the rack 7, the rack 7 no longer moves in a straight line, but rotates instead, so as to further enrich the number of target positions of the air guide plate 2 and increase the differences between multiple target positions.

[0126] When the center of curvature of the third arc segment A6A7 is located on the side of the rack 7 facing the gear 61, when the gear 61 is engaged with the teeth corresponding to the third tooth segment 713 on the rack 7, the gear 61 and the rack 7 are internally engaged, driving the air guide plate 2 to rotate along the second direction; when the center of curvature of the third arc segment A6A7 is located on the side of the rack 7 away from the gear 61, when the gear 61 is engaged with the teeth corresponding to the third tooth segment 713 on the rack 7, the gear 61 and the rack 7 are externally engaged, driving the air guide plate 2 to rotate along the first direction.

[0127] Alternatively, as Figure 31 As shown, the pitch curve of the rack 7 also includes a third transition segment A5A6, which is connected between the third arc segment A6A7 and the first straight segment A4A5. The third transition segment A5A6 is arc-shaped and the tangent of the starting end of the third transition segment A5A6 coincides with the first straight segment A4A5.

[0128] The first straight segment A4A5, the third transition segment A5A6, and the third arc segment A6A7 are arranged in sequence. The starting end of the third transition segment A5A6 is the end of the third transition segment A5A6 that is connected to the first straight segment A4A5.

[0129] The third arc segment A6A7 cannot be tangent to the first straight segment A4A5, that is, the point of intersection (meshing point) of the gear 61 and the rack 7 moving along the first straight segment A4A5 does not coincide with the meshing point of the gear 61 and the third arc segment A6A7, and therefore, the third transition segment A5A6 is added to adjust the position of the meshing point of the gear 61 and the rack 7.

[0130] The third transition segment A5A6 is a circular arc on the pitch curve of the gear 61.

[0131] Alternatively, as shown in FIG. 7, the pitch curve of the rack 7 further includes a second straight segment A7A8 connected at one end of the third arc segment A6A7 away from the first straight segment A4A5, and the second straight segment A7A8 coincides with the tangent line at the terminal end of the third arc segment A6A7. Figure 31

[0132] The tooth corresponding to the second straight segment A7A8 on the rack 7 is a fifth tooth segment 715.

[0133] The first straight segment A4A5, the third arc segment A6A7, and the second straight segment A7A8 are sequentially arranged along the length direction of the rack 7.

[0134] The second straight segment A7A8 coincides with the tangent line at the terminal end of the third arc segment A6A7 (i.e., one end of the third arc segment A6A7 connected to the second straight segment A7A8), so that the gear 61 can be smoothly switched from meshing with the fourth tooth segment 714 to meshing with the fifth tooth segment 715.

[0135] Alternatively, as shown in FIG. 7, the pitch curve of the rack 7 further includes a fourth arc segment A8A9 connected at one end of the second straight segment A7A8 away from the third arc segment A6A7, the tangent line at the starting end of the fourth arc segment A8A9 coincides with the second straight segment A7A8, and the center of curvature O4 of the fourth arc segment A8A9 is located on the side of the rack 7 facing or away from the gear 61. Figure 31 When the center of curvature of the fourth arc segment A8A9 is located on the side of the rack 7 facing the gear 61, the tooth corresponding to the third arc segment A6A7 on the rack 7 is a sixth tooth segment 716.

[0136] The third arc segment A6A7, the second straight segment A7A8, and the fourth arc segment A8A9 are sequentially arranged along the length direction of the rack 7.

[0137]

[0138] ​​The tangent of the starting end of the fourth arc segment A8A9 (i.e., the end of the fourth arc segment A8A9 connected to the second straight line segment A7A8) coincides with the second straight line segment A7A8, so that the gear 61 can smoothly switch from meshing with the teeth corresponding to the second straight line segment A7A8 to meshing with the teeth corresponding to the fourth arc segment A8A9.

[0139] The embodiment of the present disclosure further provides a guide member 84. The connecting rod is provided with a first guide portion 72; the guide member 84 is provided with a first guide matching portion 81; during the opening process of the air deflector 2, the first guide portion 72 is in a guiding position matching with the first guide matching portion 81 and a separation position (such as a position) separated from the first guide matching portion 81. Figure 17 As shown), Figure 3 、 Figure 12 As shown, in the guide position, the first guide portion 72 is used to guide the movement of the connecting rod.

[0140] During the opening process of the air guide plate 2, the first guide portion 72 and the first guide matching portion 81 have a matching guiding position and a separated position, that is, the first guide portion 72 and the first guide matching portion 81 are not always in a matching state. When the first guide portion 72 and the first guide matching portion 81 do not need to match, the first guide portion 72 and the first guide matching portion 81 are separated, thereby reducing the matching length of the first guide portion 72 and / or the first guide matching portion 81 and reducing the size of the driving device for the air-conditioning air guide plate 2.

[0141] Optionally, one of the first guide portion 72 and the first guide matching portion 81 is a first guide groove 811, and the other is a first guide column 721, as shown in FIG. Figure 3 、 Figure 12 As shown, in the guiding position, the first guide post 721 is located in the first guide groove 811 and can slide relative to the first guide groove 811; Figure 17 As shown, in the separated position, the first guide post 721 is located outside the first guide slot 811 .

[0142] The first guide post 721 is adapted to the first guide groove 811. In the guide position, the first guide post 721 is located in the first guide groove 811. As the connecting rod moves, the first guide post 721 slides relative to the first guide groove 811, guiding and limiting the movement of the connecting rod, so that the connecting rod moves along a preset motion trajectory.

[0143] In the separation position, the first guide post 721 is located outside the first guide groove 811 and no longer cooperates with the first guide groove 811, and no longer has a guiding and limiting effect on the movement of the connecting rod.

[0144] Optionally, the connecting rod is further provided with a second guide part, the guide 84 is provided with a second guide matching part, and the second guide part and the second guide matching part are matched when the first guide part 72 is in the separation position, so as to guide the movement of the connecting rod.

[0145] When the first guide part 72 and the first guide matching part 81 are separated, i.e. the first guide part 72 is in the separation position, the second guide part and the second guide matching part are matched, so as to guide the movement of the connecting rod, so that the connecting rod can move along a preset trajectory and avoid deviating from the preset trajectory.

[0146] The shape of the first guide groove 811 needs to be determined according to the movement trajectory of the connecting rod and the forms of the second guide part and the second guide matching part.

[0147] In a specific embodiment, the first guide groove 811 includes a straight line segment and / or a curved line segment, for example, as shown in Figure 17 The first guide groove 811 is in the form of a broken line, and it can be understood that the first guide groove 811 can also not be in the form of a broken line, for example, in the form of an arc. When moving from the closed position to the small ring embrace air supply position, the first guide column 721 is located in the first guide groove 811 and can slide relative to the first guide groove 811, and after the small ring embrace air supply position, the first guide column 721 is out of the first guide groove 811.

[0148] Optionally, when the first guide part 72 is in the guide position, i.e. the first guide part 72 is matched with the first guide matching part 81, the second guide part and the second guide matching part are matched.

[0149] In this way, when the first guide part 72 is in the guide position, the cooperation of the first guide part 72 and the first guide matching part 81 and the cooperation of the second guide part and the second guide matching part jointly guide the movement of the connecting rod, thereby improving the stability of the movement of the connecting rod, and some movement forms of the connecting rod cannot be realized by relying on the cooperation of a single guide part and a guide matching part, for example, the plane rotation of the connecting rod. At this time, the cooperation of the first guide part 72 and the first guide matching part 81 and the cooperation of the second guide part and the second guide matching part realize the cooperation of multiple guide parts and guide matching parts, can realize more diversified movement forms of the connecting rod, and make the selectivity of the movement form of the connecting rod greater.

[0150] In the entire opening process of the air deflector 2, as shown in Figures 10 to 30 The second guide part and the second guide matching part are always matched, or the second guide part and the second guide matching part will also switch between the matched state and the unmatched state.

[0151] Optionally, the second guide portion comprises a first sub-guide portion 74 and a second sub-guide portion 75, and the second guide cooperating portion comprises a first sub-guide cooperating portion for cooperating with the first sub-guide portion 74 and a second sub-guide cooperating portion for cooperating with the second sub-guide portion 75; wherein the first sub-guide portion 74 and the second sub-guide portion 75 are arranged on the same side of the connecting rod.

[0152] The guide 84 is fixedly arranged on the housing 1. For example, the guide 84 comprises a mechanism box, the mechanism box comprises a box body 84 and a box cover 85 which are buckled together, the connecting rod is arranged in the mechanism box between the box body 84 and the box cover 85, and the connecting rod moves between a retracted position in the mechanism box and an extended position out of the mechanism box. When the connecting rod extends out of the mechanism box, the connecting rod drives the air deflector 2 to move.

[0153] The first sub-guide portion 74 and the second sub-guide portion 75 are arranged on the same side of the connecting rod, the first sub-guide cooperating portion and the second sub-guide cooperating portion are arranged on the box body 84, the first sub-guide portion 74 cooperates with the first sub-guide cooperating portion, and the second sub-guide portion 75 cooperates with the second sub-guide cooperating portion, so that the movement of the connecting rod is stable.

[0154] In one specific embodiment, as shown in Figure 3 and Figure 4 , the first sub-guide portion 74 comprises a first sub-guide groove 78, the first sub-guide cooperating portion comprises a first sub-guide column 82, the second sub-guide portion 75 comprises a second sub-guide column 751, the second sub-guide cooperating portion comprises a second sub-guide groove 83, the first sub-guide column 82 is in sliding connection with the first sub-guide groove 78, and the second sub-guide column 751 is in sliding connection with the second sub-guide groove 83.

[0155] In another specific embodiment, the first sub-guide portion 74 comprises a first sub-guide column 82, the first sub-guide cooperating portion comprises a first sub-guide groove 78, the second sub-guide portion 75 comprises a second sub-guide groove 83, the second sub-guide cooperating portion comprises a second sub-guide column 751, the first sub-guide column 82 is in sliding connection with the first sub-guide groove 78, and the second sub-guide column 751 is in sliding connection with the second sub-guide groove 83.

[0156] The sliding connection of the first sub-guide column 82 and the first sub-guide groove 78 means that when the first sub-guide column 82 and the first sub-guide groove 78 are matched, the first sub-guide column 82 is located in the first sub-guide groove 78 and can slide relative to the first sub-guide groove 78, thereby guiding the movement of the connecting rod; when the first sub-guide column 82 and the first sub-guide groove 78 are not matched, the first sub-guide column 82 is located outside the first sub-guide groove 78, and there is no guiding effect on the movement of the connecting rod; the sliding connection of the second sub-guide column 751 and the second sub-guide groove 83 means that when the second sub-guide column 751 and the second sub-guide groove 83 are matched, the second sub-guide column 751 is located in the second sub-guide groove 83 and can slide relative to the second sub-guide groove 83, thereby guiding the movement of the connecting rod; when the second sub-guide column 751 and the second sub-guide groove 83 are not matched, the second sub-guide column 751 is located outside the second sub-guide groove 83, and there is no guiding effect on the movement of the connecting rod.

[0157] When the first sub-guide part 74 includes the first sub-guide groove 78, the second sub-guide part 75 includes the second sub-guide column 751; when the first sub-guide part 74 includes the first sub-guide column 82, the second sub-guide part 75 includes the second sub-guide groove 83, so as to avoid that the first sub-guide part 74 and the second sub-guide part 75 are both in the form of grooves or columns, thereby more reasonably utilizing the space of the connecting rod, making the connecting rod structure compact, and avoiding that the size of the connecting rod or the box body 84 is too large.

[0158] The shapes of the first sub-guide groove 78 and the second sub-guide groove 83 need to be determined according to the movement trajectory of the connecting rod, the form of the first guide part 72 and the first guide matching part 81.

[0159] The first sub-guide groove 78 includes a straight line segment and / or a curve segment. The first guide groove 811 extends along the length direction of the connecting rod, and the first sub-guide groove 78 includes a first guide segment 781, a second guide segment 782, a third guide segment 783 and a fourth guide segment 784 arranged in sequence. The first guide segment 781 includes a straight line segment and / or a curve segment connected in sequence, as shown in Figure 4 and Figure 13 From the closed position to the small ring embrace air supply position, the first sub-guide column 82 is located in the first guide segment 781 and can slide relative to the first guide segment 781; the first sub-guide groove 78 further includes the second guide segment 782; from the small ring embrace air supply position to the large ring embrace air supply position, as shown in Figure 18 the first sub-guide column 82 is located in the second guide segment 782 and can slide relative to the second guide segment 782, and the second guide segment 782 is in a curve shape, for example, an arc shape; as shown in Figure 20 the first sub-guide groove 78 further includes the third guide segment 783, from the large ring embrace air supply position to the heating lower blowing position, the first sub-guide column 82 is located in the third guide segment 783 and can slide relative to the third guide segment 783, and the third guide segment 783 includes a curve segment and / or a straight line segment; as shown inFigure 23 As shown, the first sub-guide slot 78 further comprises a fourth guide segment 784, from the heating lower-blowing position to the maximum air supply position, the first sub-guide column 82 is located in the fourth guide segment 784 and can slide relative to the fourth guide segment 784, the fourth guide segment 784 comprises a curved segment and / or a straight segment, for example, in a curved shape.

[0160] The second sub-guide slot 83 comprises a straight segment and / or a curved segment. The second sub-guide slot 83 comprises a fifth guide segment 831, a sixth guide segment 833, a seventh guide segment 834 and an eighth guide segment 835 arranged in sequence. The fifth guide segment 831 comprises a straight segment and / or a curved segment, for example, in a curved shape. Figure 3 and Figure 12 As shown, from the closed position to the small ring-around air supply position, the second sub-guide column 751 is located in the fifth guide segment 831 and can slide relative to the fifth guide segment 831, the fifth guide segment 831 comprises a first sub-segment 8311 and a second sub-segment 8314, the first sub-segment 8311 comprises a first end 8312 and a second end 8313 located in the length direction of the first sub-segment 8311, the second sub-segment 8314 is located on one side of the first sub-segment 8311, and is in communication with the first sub-segment 8311 and the communication position is between the first end 8312 and the second end 8313, the air deflector 2 moves from the closed position to the cooling upward position, and the second sub-guide column 751 moves from the first end 8312 to the second end, as shown. Figure 12 As shown, in the cooling upward position, the second sub-guide column 751 moves to the second end; as shown. Figure 17 As shown, from the cooling upward position to the small ring-around air supply position, the second sub-guide column 751 slides reversely (i.e. from the second end to the first end) from the second end 8313 to the communication position of the first sub-segment 8311 and the second sub-segment 8314, and slides into the second sub-segment 8314, the first sub-segment 8311 is in a curved shape, and the second sub-segment 8314 is in a straight shape, the communication position of the second sub-segment 8314 and the first sub-segment 8311 forms a first fold angle 8315, when the second sub-guide column 751 moves to the communication position of the first sub-segment 8311 and the second sub-segment 8314, because the size of the communication position of the first sub-segment 8311 and the second sub-segment 8314 is larger than the size of the second sub-guide column 751, the cooperation of the second sub-guide column 751 and the communication position has a weak limiting effect on the connecting rod and plays an auxiliary role; from the small ring-around air supply position to the large ring-around air supply position, the second sub-guide column 751 is located in the sixth guide segment 833 and can slide relative to the sixth guide segment 833, the sixth guide segment 833 and the second sub-segment 8314 form a second fold angle 832, as shown.

Figure 26As shown, from the large ring air supply position to the heating down-blow position, the second sub-guide column 751 is located in the seventh guide segment 834 and can slide relative to the seventh guide segment 834, the seventh guide segment 834 includes a third sub-segment 8341 and a fourth sub-segment 8342, and during the opening process of the air deflector 2, the second sub-guide column 751 is sequentially located in the third sub-segment 8341 and the fourth sub-segment 8342, the third sub-segment 8341 is located in the same circular arc shape as the sixth guide segment 833, the fourth sub-segment 8342 is linear, and the communication between the fourth sub-segment 8342 and the third sub-segment 8341 forms a third folding angle 8343; as shown, Figure 26 As shown, from the heating down-blow position to the maximum air supply position, the second sub-guide column 751 is located in the eighth guide segment 835 and can slide relative to the eighth guide segment 835, the eighth guide segment 835 is curved, for example, arc-shaped, and the communication between the eighth guide segment 835 and the fourth sub-segment 8342 forms a fourth folding angle 8344, and at the heating down-blow position, the second sub-guide column 751 is located at the fourth folding angle 8344.

[0161] Optionally, as shown, Figure 6 The second guide part includes a first sub-guide part 74 and a third sub-guide part 76, and the second guide cooperating part includes a first sub-guide cooperating part for cooperating with the first sub-guide part 74 and a third sub-guide cooperating part 86 for cooperating with the third sub-guide part 76; wherein the first sub-guide part 74 and the third sub-guide part 76 are located on opposite sides of the connecting rod.

[0162] The first sub-guide part 74 and the third sub-guide part 76 are respectively arranged on opposite sides of the connecting rod, which can guide the movement of opposite sides of the connecting rod respectively, so that the movement of the connecting rod is more stable, and the space of the connecting rod can be reasonably utilized, avoiding the situation that the first sub-guide part 74 and the third sub-guide part 76 are arranged on the same side of the connecting rod, resulting in an excessively large size of the connecting rod.

[0163] The third sub-guide cooperating part 86 is arranged on the box cover 85.

[0164] Optionally, one of the first sub-guide part 74 and the first sub-guide cooperating part includes a first sub-guide column 82, and the other includes a first sub-guide groove 78, and the first sub-guide column 82 is in sliding connection with the first sub-guide groove 78; as shown, Figure 6 One of the third sub-guide part 76 and the third sub-guide cooperating part 86 includes a third sub-guide column 861, and the other includes a third sub-guide groove 77, and the third sub-guide column 861 is in sliding connection with the third sub-guide groove 77.

[0165] The third sub-guide column 861 is matched with the third sub-guide slot 77. When the third sub-guide column 861 is matched with the third sub-guide slot 77, the third sub-guide column 861 is located in the third sub-guide slot 77 and can slide relative to the third sub-guide slot 77 to guide the movement of the connecting rod. When the third sub-guide column 861 is not matched with the third sub-guide slot 77, the third sub-guide column 861 is located outside the third sub-guide slot 77 and has no guiding effect on the movement of the connecting rod.

[0166] The third sub-guide slot 77 includes a straight line segment and / or a curved segment. The third sub-guide slot 77 includes a ninth guide segment 771, a tenth guide segment 772, an eleventh guide segment 773, and a twelfth guide segment 774 arranged in sequence. As shown in Figure 6 、 Figure 14 and Figure 15 , when the air deflector 2 moves from the closed position to the small ring-around air supply position, the third sub-guide column 861 is located in the ninth guide segment 771 and can slide relative to the ninth guide segment 771, that is, matched with the ninth guide segment 771. The ninth guide segment 771 includes a fifth sub-segment 7711 and a sixth sub-segment 7712. The communication between the fifth sub-segment 7711 and the sixth sub-segment 7712 forms a fifth fold angle 7713. During the process that the air deflector 2 is opened from the closed position to the cooling upward position, the third sub-guide column 861 is matched with the fifth sub-segment 7711. As shown in Figure 14 , in the cooling upward position, the third sub-guide column 861 is located at the fifth fold angle 7713. From the cooling upward position to the small ring-around air supply position, the third sub-guide column 861 is matched with the sixth sub-segment 7712. The fifth sub-segment 7711 includes a straight line segment and / or a curved segment. The sixth sub-segment 7712 includes a straight line segment and / or a curved segment. As shown in Figure 22 , when the air deflector 2 moves from the small ring-around air supply position to the large ring-around air supply position, the third sub-guide column 861 is located in the tenth guide segment 772 and can slide relative to the tenth guide segment 772, that is, matched with the tenth guide segment 772. The communication between the ninth guide segment 771 and the tenth guide segment 772 forms a sixth fold angle 775. As shown in Figure 15 , in the small ring-around air supply position, the third sub-guide column 861 is located at the sixth fold angle 775. The tenth guide segment 772 includes a straight line segment and / or a curved segment, for example, in an arc shape. As shown in Figure 24 , when the air deflector 2 moves from the large ring-around air supply position to the heating downward blowing position, the third sub-guide column 861 is located in the eleventh guide segment 773 and can slide relative to the eleventh guide segment 773, that is, matched with the eleventh guide segment 773. The eleventh guide segment 773 includes a straight line segment and / or a curved segment, for example, in a curved shape. As shown in Figure 30As shown, when the air guide plate 2 moves from the heating downward blowing position to the maximum air supply position, the third sub-guide column 861 is located in the twelfth guide segment 774 and can slide relative to the twelfth guide segment 774, that is, cooperates with the twelfth guide segment 774, and the twelfth guide segment 774 includes a straight segment and / or a curved segment, for example, in a curved shape.

[0167] Among them, in the process of opening the air guide plate 2 from the closed position, it passes through the cooling upward position, small surround air supply position, large surround air supply position, heating downward blowing position and maximum air supply position in sequence, and cooperates with the movement of the guide plate 3 to realize the cooling upward air supply mode, small surround air supply mode, large surround air supply mode, heating downward blowing mode and maximum air supply mode of the indoor unit in sequence.

[0168] During the opening process of the air deflector 2, the first sub-guide post 82 and the first sub-guide groove 78 always cooperate, the second sub-guide post 751 and the second sub-guide groove 83 always cooperate, and the third sub-guide post 861 and the third sub-guide groove 77 always cooperate. When the second sub-guide post 751 moves to the connection point between the first sub-segment 8311 and the second sub-segment 8314, the cooperation between the second sub-guide post 751 and the second sub-guide groove 83 plays an auxiliary role in limiting the position of the connecting rod. The cooperation between the first guide post 721 and the first sub-guide groove 78, the cooperation between the first guide post 721 and the first guide groove 811, and the cooperation between the third sub-guide post 861 and the third sub-guide groove 77 play the primary role in limiting the position of the connecting rod. When the first guide post 721 is released from the first guide groove 811, the cooperation between the first sub-guide post 82 and the first sub-guide groove 78, the cooperation between the second sub-guide post 751 and the second sub-guide groove 83, and the cooperation between the third sub-guide post 861 and the third sub-guide groove 77 jointly limit the movement of the connecting rod.

[0169] Alternatively, as Figure 20 As shown, the guide plate 3 is provided with a first connecting portion 31 and a second connecting portion 32 , and the indoor unit further includes a first connecting rod 5 , a driving component 53 and a second connecting rod 54 .

[0170] One end of the first connecting rod 5 is movably connected to the first connecting part 31; the driving component 53 is drivingly connected to the other end of the first connecting rod 5; one end of the second connecting rod 54 is configured to be movably connected to the shell 1, and the other end is fixedly connected to the second connecting part 32; wherein, along the direction close to the wind deflector 2, the first connecting part 31 and the second connecting part 32 are arranged in sequence.

[0171] The driving component 53 can be an electric motor, which is directly drivingly connected with the first connecting rod 5 or drivingly connected through a transmission member such as a gear 61. The driving component 53 drives the first connecting rod 5 to move, the first connecting rod 5 drives the guide plate 3 to move, and the movement of the guide plate 3 drives the second connecting rod 54 to move relative to the housing 1. The second connecting rod 54 can not only enhance the stability of the guide plate 3 but also cooperate with the first connecting rod 5 to achieve the target air guiding position of the guide plate 3.

[0172] In the direction from the guide plate 3 to the air deflector 2, the first connecting portion 31 and the second connecting portion 32 are sequentially arranged, that is, the distance between the first connecting portion 31 and the air deflector 2 is greater than the distance between the second connecting portion 32 and the air deflector 2, so that the guide plate 3 can move towards the air deflector 2 to cooperate with the air deflector 2 to achieve the target air guiding mode.

[0173] As shown in Figure 12 and Figure 19 , the guide plate 3 is flipped towards the air deflector 2 to open the second air outlet area 112, thereby achieving the air supply mode of the refrigeration updraft and the large ring air supply mode.

[0174] The driving component 53 is not drivingly connected with the second connecting rod 54, that is, the movement of the second connecting rod 54 is directly driven by the guide plate 3 rather than the driving component 53.

[0175] As shown in Figure 20 , the box body 84 is provided with a avoiding space 41, and the driving component 53, the first connecting rod 5 and the second connecting rod 54 are all arranged outside the box body 84 and located in the avoiding space 41.

[0176] The opening amplitude of the guide plate 3 is smaller than that of the air deflector 2, so the lengths of the first connecting rod 5 and the second connecting rod 54 are relatively small. In order to drive the guide plate 3 by the first connecting rod 5 and the second connecting rod 54, the avoiding space 41 is arranged on the side of the box body 84 facing the first air outlet area 111.

[0177] Optionally, as shown in Figure 22 , the distance between the first connecting portion 31 and the middle part of the guide plate 3 in the width direction is smaller than the distance between the second connecting portion 32 and the middle part of the guide plate 3 in the width direction.

[0178] In this way, the length of the trajectory of the movement of the first connecting rod 5 can be reduced, and the space occupied by the first connecting rod 5 can be reduced.

[0179] Optionally, as shown in Figure 20 and Figure 22As shown, the first connecting portion 31 is provided at the middle portion of the guide plate 3 in the width direction, i.e., the distance between the first connecting portion 31 and the middle portion of the guide plate 3 in the width direction is zero, and the second connecting portion 32 is provided on the guide plate 3 between the first connecting portion 31 and the air deflector 2. This can further reduce the length of the movement path of the first connecting rod 5 and reduce the space occupied by the first connecting rod 5.

[0180] The first connecting portion 31 includes a mounting protrusion on the inner wall surface of the guide plate 3 .

[0181] Alternatively, as Figure 22 As shown, the second connecting rod 54 is provided with a notch 541 for avoiding the housing 1 . The notch 541 is located on the side of the second connecting rod 54 facing the wind guide plate 2 , so that the second connecting rod 54 is bent toward the first connecting rod 5 .

[0182] After the guide plate 3 is turned toward the air guide plate 2, the housing 1 is partially located in the notch 541, preventing the second connecting rod 54 from interfering with the housing 1 after extending with the guide plate 3. Specifically, the housing 1 includes a frame, and the notch 541 is used to prevent the second connecting rod 54 from interfering with the frame.

[0183] Optionally, the second connecting rod 54 is rotatably connected to the shell 1, so that the guide plate 3 moves under the drive of the first connecting rod 5, and the guide plate 3 drives the second connecting rod 54 to rotate around the shell 1, thereby realizing the rotation of the guide plate 3 toward the air guide plate 2.

[0184] Optionally, the first connecting rod 5 is slidably connected to the first connecting portion 31 to increase the freedom of movement of the guide plate 3 and enable the guide plate 3 to have more wind-guiding positions. In this case, one of the first connecting rod 5 and the first connecting portion 31 is provided with a slide groove extending from the first connecting portion 31 to the second connecting portion 32, and the other of the first connecting rod 5 and the first connecting portion 31 is provided with a sliding shaft, which is disposed in the slide groove and can slide relative to the slide groove along the length of the slide groove.

[0185] Or, as Figure 22 As shown, the first connecting rod 5 includes a first sub-rod 51 and a second sub-rod 52. One end of the first sub-rod 51 is drivingly connected to the driving component 53, the other end of the first sub-rod 51 is rotationally connected to one end of the second sub-rod 52, and the other end of the second sub-rod 52 is rotationally connected to the first connecting part 31.

[0186] The driving component 53 drives the first sub-rod 51 to move, the first sub-rod 51 drives the second sub-rod 52 to move, and the second sub-rod 52 drives the guide plate 3 to move, thereby realizing the opening and closing of the second air outlet area 112 .

[0187] Alternatively, as Figure 22 As shown, the length of the first connecting rod 5 is greater than the length of the second connecting rod 54 .

[0188] During the movement of the guide plate 3, the first connecting rod 5 provides power to drive the guide plate 3 to rotate around the rotating connection between the second connecting rod 54 and the shell 1. The second connecting rod 54 mainly provides a rotation point for the movement of the guide plate 3. Therefore, the maximum extension length of the first connecting rod 5 needs to be greater than the maximum extension length of the second connecting rod 54 during the opening of the guide plate 3.

[0189] The length of the first connecting rod 5 refers to the total length of the first connecting rod 5. In the case where the first connecting rod 5 includes the first sub-rod 51 and the second sub-rod 52, the length of the first connecting rod 5 refers to the sum of the lengths of the first sub-rod 51 and the second sub-rod 52.

[0190] Optionally, as shown in Figure 3 The inner wall surface of the air deflector 2 is provided with a avoiding groove 21. When the air deflector 2 and the guide plate 3 are closed to the first air outlet area 111 and the second air outlet area 112 respectively, that is, when the air deflector 2 and the guide plate 3 are both in the closed position, the end of the guide plate 3 close to the air deflector 2 is inserted into the avoiding groove 21.

[0191] When the air deflector 2 and the guide plate 3 are both in the closed position, the end of the guide plate 3 close to the air deflector 2 is inserted into the avoiding groove 21, so that the guide plate 3 and the air deflector 2 partially overlap, avoiding the generation of gaps between the air deflector 2 and the guide plate 3, and enhancing the appearance of the indoor unit.

[0192] In this way, when opening the air outlet, if the air deflector 2 needs to open the first air outlet area 111 and the guide plate 3 needs to open the second air outlet area 112, the air deflector 2 needs to act first, and after the air deflector 2 leaves the second air outlet area 112, the guide plate 3 opens. When closing the air outlet, the guide plate 3 closes the second air outlet area 112 first, and then the air deflector 2 closes the first air outlet area 111.

[0193] The embodiment of the second aspect of the application provides an air conditioner, which includes an indoor unit, the indoor unit includes an air deflector 2 and a driving device for the air deflector 2 of the air conditioner as described in any one of the above embodiments, and the rack 7 is connected with the air deflector 2.

[0194] The air conditioner provided by the embodiment of the second aspect of the application has all the beneficial effects of the driving device for the air deflector 2 of the air conditioner as described in any one of the above embodiments, and thus is not described here again.

[0195] The above description and drawings suffice to fully enable one skilled in the art to practice the embodiments of the present disclosure.
