Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a rack and an air conditioner. Background Art

[0002] Currently, for driven parts with multiple target positions, the drive device is often more complex in structure. For example, if the driven part is an air deflector, as the air deflector's air guide positions become more and more diverse, the structure of the air deflector drive device is becoming more and more complex.

[0003] The related technology discloses a driving mechanism, which includes an air guide plate, a connecting rod assembly, a rotating part, a fixed guide groove and a driving unit. The connecting rod assembly is slidably arranged in the fixed guide groove. The first end of the connecting rod assembly is connected to the air guide plate, and the second end of the connecting rod assembly is movably arranged in the rotating guide groove on the rotating part. The driving unit drives the rotating part to rotate, and the connecting rod assembly moves in the fixed guide groove through the rotation of the rotating part, thereby driving the air guide plate to move.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] The connecting rod assembly includes a first connecting rod and a second connecting rod, which work together to switch the wind deflector between different opening positions. In other words, during the opening process of the wind deflector, the position of the wind deflector needs to be determined by the first connecting rod and the second connecting rod. On the one hand, the two connecting rods (the first connecting rod and the second connecting rod) increase the complexity of the drive mechanism. On the other hand, any deviation in either the first connecting rod or the second connecting rod will cause the wind deflector to fail to reach the target position, resulting in low positioning accuracy of the wind deflector.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0008] The embodiments of the present disclosure provide a rack and an air conditioner to solve the problems of a complex driving mechanism and low position accuracy of an air guide plate in the related art.

[0009] According to a first aspect of an embodiment of the present utility model, a rack is provided, which is configured to engage with a gear and the gear is located on one side of the rack, and the rack is connected to a driven member; the pitch curve of the rack includes at least two of a first arc segment, a second arc segment and a first straight line segment, wherein one of the curvature center of the first arc segment and the curvature center of the second arc segment is located on the side of the rack facing the gear, and the other is located on the side of the rack away from the gear.

[0010] Optionally, the pitch curve of the rack includes a first arc segment, a second arc segment and a first straight segment, and the first arc segment, the second arc segment and the first straight segment are arranged in sequence along the length direction of the rack.

[0011] Optionally, when the pitch curve of the rack includes a first arc segment and a first straight line segment connected together, the pitch curve of the rack also includes: a first transition segment connected between the first arc segment and the first straight line segment, the first transition segment is arc-shaped and the tangent of the end of the first transition segment coincides with the first straight line segment; when the pitch curve of the rack includes a second arc segment and a first straight line segment connected together, the pitch curve of the rack also includes: a second transition segment connected between the second arc segment and the first straight line segment, the second transition segment is arc-shaped and the tangent of the end of the second transition segment coincides with the first straight line segment.

[0012] Optionally, the first transition section or the second transition section is an arc on the gear pitch curve.

[0013] Optionally, when the pitch curve of the rack includes a first straight line segment, the pitch curve of the rack also includes: a third arc segment, connected to the end of the first straight line segment away from the first arc segment or the second arc segment, and the center of curvature of the third arc segment is located on the side of the rack toward or away from the gear.

[0015] Optionally, the third transition segment is an arc on the gear pitch curve.

[0016] Optionally, the pitch curve of the rack further includes: a second straight line segment connected to an end of the third arc segment away from the first straight line segment, and the second straight line segment coincides with a tangent line of a terminal end of the third arc segment.

[0018] According to the second aspect of the embodiment of the present utility model, an air conditioner is provided, including an indoor unit, the indoor unit including: an air guide plate; a gear; a rack as described in any one of the above embodiments, the rack is meshed with the gear and connected to the air guide plate, wherein the driven component is the air guide plate.

[0019] The rack and air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0020] When the pitch curve of the rack includes a first arc segment and a second arc segment, the rack rotates in a different direction when the gear meshes with the teeth corresponding to the first arc segment on the rack and when the gear meshes with the gear teeth corresponding to the second arc segment on the rack, resulting in different rotation directions of the driven part. Thus, the rack can drive the driven part to rotate in different directions, eliminating the need for additional connecting rods to cooperate with the rack to achieve different rotation directions of the driven part. This simplifies the rack structure and, in addition, eliminates the need for additional connecting rods to control the position of the driven part through the rack, preventing the connecting rod from affecting the position of the driven part and reducing factors that affect the position of the driven part, thereby improving the position accuracy of the driven part.

[0021] When the pitch curve of the rack includes a first arc segment and a first straight segment, when the gear meshes with the teeth corresponding to the first arc segment on the rack, it can drive the rack to rotate, thereby driving the driven part to rotate. When the gear meshes with the teeth corresponding to the first straight segment on the rack, it can drive the rack to move in a straight line, thereby driving the driven part to move in a straight line, thereby realizing various motion forms of the driven part and further realizing various target positions of the driven part.

[0022] When the pitch curve of the rack includes a second arc segment and a first straight segment, when the gear meshes with the teeth corresponding to the second arc segment on the rack, it can drive the rack to rotate, thereby driving the driven part to rotate. When the gear meshes with the teeth corresponding to the first straight segment on the rack, it can drive the rack to move in a straight line, thereby driving the driven part to move in a straight line, thereby realizing various motion forms of the driven part and further realizing various target positions of the driven part.

[0023] When the pitch curve of the rack includes a first arc segment, a second arc segment and a first straight segment, the target positions of the driven member can be further increased, and a large difference can be made between the various target positions.

[0065] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0066] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0067] Combine Figure 1-30 As shown, an embodiment of the present disclosure provides a connecting rod.

[0068] The connecting rod is configured to be connected to the driven member to drive the driven member to move.

[0069] The connecting rod is fixedly connected or movably connected to the driven member. When it is movably connected, it can be a rotating connection or a sliding connection.

[0070] The connecting rod can be in the form of a rack 7, which is connected to the driven part and is used to drive the driven part to move. It is understandable that the connecting rod can also be a component without teeth, and the movement of the connecting rod can also drive the driven part to move. When the connecting rod is a rack 7, the embodiment of the present disclosure also provides a gear 61 that meshes with the rack 7. When the gear 61 and the rack 7 are applied to an air conditioner, the driven part can be an air deflector 2. It is understandable that the driven part can also be other parts that need to have multiple target positions, especially those that need to be flipped. In this application, the driven part is an air deflector 2 as an example for explanation.

[0071] 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 outlet duct and is provided with an air inlet and an air outlet. The air inlet and the air outlet are both connected to the air duct.

[0072] The fan and 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.

[0073] The air guide plate 2 is provided at the air outlet and can move relative to the air outlet to achieve various air guide forms.

[0074] The driving device for the air-conditioning air guide plate 2 includes the aforementioned gear 61 and rack 7 .

[0075] The gear 61 is controlled to rotate.

[0076] like Figure 5 and Figure 13As shown, the rack 7 is provided with a first tooth segment 711 and a second tooth segment 712 sequentially arranged along the length direction of the rack 7, and the first tooth segment 711 and the second tooth segment 712 are both capable of meshing with the gear 61, and the rack 7 is connected to the air guide plate 2; wherein, when the gear 61 is meshed with the first tooth segment 711, the gear 61 and the rack 7 are in one of internal meshing and external meshing; when the gear 61 is meshed with the second tooth segment 712, the gear 61 and the rack 7 are in the other of internal meshing and external meshing.

[0077] 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 it can intermittently drive the gear 61 to rotate through other transmission members, which can be a driving gear 61 or a belt.

[0078] The rack 7 is connected to the wind guide plate 2 and can be a fixed connection. For example, one of the rack 7 and the wind guide plate 2 is provided with a connecting column, and the other is provided with a connecting hole. The connecting column and the connecting hole are adapted to each other, and 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 to prevent the connecting column from rotating relative to the connecting hole, thereby achieving the fixation of the rack 7 and the wind guide plate 2. In this way, the movement of the rack 7 can be accurately transmitted to the wind guide plate 2 to better control the movement of the wind guide plate 2; the rack 7 and the wind guide plate 2 can also be a movably connected, such as a rotating connection or a sliding connection.

[0079] like Figure 5 and Figure 13 As shown, when the gear 61 is meshed with the first tooth segment 711, the gear 61 and the rack 7 are in internal meshing; when the gear 61 is meshed with the second tooth segment 712, the gear 61 and the rack 7 are in external meshing. Alternatively, when the gear 61 is meshed with the first tooth segment 711, the gear 61 and the rack 7 are in external meshing; when the gear 61 is meshed with the second tooth segment 712, the gear 61 and the rack 7 are in internal meshing.

[0080] In this way, the gear 61 and the rack 7 will switch between internal and external meshing during the meshing process. Since the rotation center of the rack 7 is different during internal and external meshing, the air guide plate 2 will rotate in different directions, and can be driven to rotate in different directions. For example, the air guide plate 2 can rotate both clockwise and counterclockwise, thereby achieving both cooling upward and heating downward requirements.

[0081] Due to the change in the rotation center of the rack 7, the rotation direction of the air guide plate 2 changes, so that the rack 7 can drive the air guide plate 2 to rotate in different directions, and there is no need to set up other racks 7 or connecting rods, thereby greatly simplifying the structure of the driving device for the air-conditioning air guide plate 2.

[0082] In other words, there is only one rack 7 , and no other connecting rods are connected to the air guide plate 2 .

[0083] During the opening process of the air deflector 2, the steering of the air deflector 2 is achieved by switching between the internal and external engagement of the gear 61 and the rack 7. Therefore, during the opening process of the air deflector 2, the motor rotates in one direction throughout the entire process, simplifying the control of the motor.

[0084] Alternatively, as Figure 18 As shown, the rack 7 is further provided with a third tooth segment 713 . The third tooth segment 713 is a straight tooth segment, and the third tooth segment 713 can mesh with the gear 61 .

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] Taking the air conditioner as a wall-mounted air conditioner as an example, the first air outlet area 111 and the second air outlet area 112 are sequentially arranged in the up and down directions. Figure 12 As shown, the first air outlet area 111 is located below the second air outlet area 112. It is understandable that the first air outlet area 111 can also be located above the second air outlet area 112.

[0092] like Figures 19 to 22 As shown, when the gear 61 is engaged with the fourth tooth segment 714, the air guide plate 2 rotates in the second direction. At this time, the guide plate 3 rotates toward the air guide plate 2, and the guide plate 3 abuts against the guide plate to realize large-scale encircling air supply. Under the same conditions, the air supply volume of the large-scale encircling air supply is greater than that of the small-scale encircling air supply.

[0093] Optionally, a central angle corresponding to the fourth tooth segment 714 is greater than a central angle corresponding to the second tooth segment 712 .

[0094] In this way, the gear 61 is engaged with the fourth tooth segment 714, which can drive the air guide plate 2 to rotate at a larger angle. The rotation angle is greater than the rotation angle of the air guide plate 2 driven by the engagement of the gear 61 with the second tooth segment 712. The large-angle rotation of the air guide plate 2 drives the air guide plate 2 to move to the heating downward blowing position, thereby realizing heating downward blowing.

[0095] The central angle corresponding to the fourth tooth segment 714 is the central angle subtended by the fourth tooth segment 714 ; the central angle corresponding to the second tooth segment 712 is the central angle subtended by the second tooth segment 712 .

[0096] Alternatively, as Figure 23 As shown, the rack 7 is further provided with a fifth tooth segment 715. 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.

[0097] The fifth tooth segment 715 extends along the length of the rack 7 and is a straight tooth segment. When the gear 61 engages with the fifth tooth segment 715, 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.

[0098] After the air guide plate 2 is moved from the heating downward blowing position, it extends in a straight line to cooperate with the rotation of the air guide plate 2 in different directions, thereby realizing various air guiding forms of the air guide plate 2.

[0099] Alternatively, as Figure 26 As 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 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, the fifth tooth segment 715 and the sixth tooth segment 716 are arranged in sequence, and the sixth tooth segment 716 can be engaged with the gear 61, and when the sixth tooth segment 716 is engaged with the gear 61, the gear 61 and the rack 7 are the other of the internal meshing and the external meshing.

[0100] When the sixth tooth segment 716 is engaged with the gear 61 , the rack 7 drives the air guide plate 2 to rotate along the second direction to reach the maximum air supply position, at which time the air supply volume can reach the maximum.

[0101] Optionally, a central angle corresponding to the sixth tooth segment 716 is greater than a central angle corresponding to the second tooth segment 712 .

[0102] In this way, the gear 61 is engaged with the sixth tooth segment 716, which can drive the air guide plate 2 to rotate at a larger angle. The rotation angle is greater than the rotation angle of the air guide plate 2 driven by the engagement of the gear 61 with the second tooth segment 712. The large-angle rotation of the air guide plate 2 drives the air guide plate 2 to move to the maximum air supply position, thereby achieving maximum air supply.

[0103] The central angle corresponding to the sixth tooth segment 716 is the central angle opposite to the sixth tooth segment 716 .

[0104] The sizes of 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, and the lengths of the third tooth segment 713 and the fifth tooth segment 715 are related to the various air-guiding positions of the air guide plate 2. In actual applications, they need to be determined based on the specific positions of the air guide plate 2.

[0105] 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 arc-shaped, and 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°, and 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.

[0106] The radius of the circle surrounding the first tooth segment 711, the radius of the circle surrounding the second tooth segment 712, the radius of the circle surrounding the fourth tooth segment 714, and the radius of the circle surrounding the sixth tooth segment 716 increase in sequence. Thus, when the angular velocity of the gear 61 remains constant, the speed of the rack 7 when the gear 61 meshes with the first tooth segment 711, the speed of the rack 7 when the gear 61 meshes with the second tooth segment 712, the speed of the rack 7 when the gear 61 meshes with the fourth tooth segment 714, and the speed of the rack 7 when the gear 61 meshes with the sixth tooth segment 716 decrease in sequence, and the speed of the air deflector 2 decreases accordingly. Because the rack 7 extends significantly out of the air outlet during the later stages of the air deflector 2 opening process, and the air deflector 2 has completely left the air outlet, the design slows down the speed of the rack 7 and the air deflector 2 as the air deflector 2 opens. This allows for smoother movement of the rack 7 and the air deflector 2, preventing shaking of the rack 7 and the air deflector 2.

[0107] like Figure 23 As shown, the gear 61 is located on one side of the rack 7, and the rack 7 is connected to the driven member.

[0108] like Figure 31 As shown, the pitch curve of the rack 7 includes at least two of the first arc segment A1A2, the second arc segment A2A3 and the first straight line segment A4A5, wherein one of the curvature center O1 of the first arc segment A1A2 and the curvature center O2 of the second arc segment 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.

[0109] When the center of curvature O1 of the first arc segment A1A2 is located on the side of the rack 7 facing the gear 61, the center of curvature O2 of the second arc segment A2A3 is located on the side of the rack 7 facing away from the gear 61. When the center of curvature of the first arc segment A1A2 is located on the side of the rack 7 facing away from the gear 61, the center of curvature of the second arc segment A2A3 is located on the side of the rack 7 facing the gear 61. Thus, when the gear 61 meshes with the teeth corresponding to the first arc segment A1A2 on the rack 7, the direction of rotation of the rack 7 is different from the direction of rotation when the gear 61 meshes with the teeth corresponding to the second arc segment A2A3 on the rack 7.

[0110] like Figure 31 As 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] The teeth on the rack 7 corresponding to the first arc segment A1A2 are the first tooth segments 711 , the teeth corresponding to the second arc segment A2A3 are the second tooth segments 712 , and the teeth corresponding to the first straight segment A4A5 are the third tooth segments 713 .

[0116] During the opening process of the air deflector 2, the gear 61 first engages with the first tooth segment 711, causing the rack 7 to rotate, thereby causing the air deflector 2 to rotate in a first direction, achieving a cooling upward movement. The gear 61 then engages with the second tooth segment 712, driving the air deflector 2 to rotate in a second direction opposite to the first direction. Subsequently, the gear 61 engages with the third tooth segment 713, causing the rack 7 to extend outward, driving the air deflector 2 to extend outward, achieving a small encircling air supply.

[0117] Optionally, when the pitch curve of the rack 7 includes a first arc segment A1A2 and a first straight line segment A4A5 connected to each other, the pitch curve of the rack 7 also 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 of the end of the first transition segment coincides with the first straight line segment A4A5.

[0118] In other words, the first arc segment A1A2, the first transition segment and the first straight segment A4A5 are arranged in sequence. The end of the first transition segment refers to the end of the first transition segment connected to the first straight segment A4A5.

[0119] The tangent direction of the end of the first arc segment A1A2 (i.e., the 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, 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.

[0120] The first transition section is an arc on the pitch curve of gear 61.

[0121] Optionally, when the pitch curve of the rack 7 includes a second arc segment A2A3 and a first straight line segment A4A5 connected to each other, the pitch curve of the rack 7 also 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 of the end of the second transition segment A3A4 coincides with the first straight line segment A4A5.

[0122] In other words, the second arc segment A2A3, the first transition segment and the first straight segment A4A5 are arranged in sequence. The end of the first transition segment refers to the end of the first transition segment connected to the first straight segment A4A5.

[0123] 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.

[0124] The first transition section is an arc on the pitch curve of gear 61.

[0125] 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 .

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] The third arc segment A6A7 cannot be tangent to the first straight segment A4A5, that is, the tangent point (meshing point) of the gear 61 and the rack 7 along the first straight segment A4A5 does not coincide with the meshing point of the gear 61 and the third arc segment A6A7. Therefore, the third transition segment A5A6 is added to adjust the position of the meshing point between the gear 61 and the rack 7.

[0131] The third transition section A5A6 is an arc on the pitch curve of gear 61.

[0132] Alternatively, as Figure 31 As shown, the pitch curve of the rack 7 also includes a second straight line segment A7A8, which is connected to the end of the third arc segment A6A7 away from the first straight line segment A4A5, and the second straight line segment A7A8 coincides with the tangent of the terminal end of the third arc segment A6A7.

[0133] The tooth on the rack 7 corresponding to the second straight line segment A7A8 is the fifth tooth segment 715 .

[0134] 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.

[0135] The tangent of the second straight segment A7A8 coincides with the terminal end of the third arc segment A6A7 (i.e., the end of the third arc segment A6A7 connected to the second straight segment A7A8), so that the gear 61 can smoothly switch from meshing with the fourth tooth segment 714 to meshing with the fifth tooth segment 715.

[0136] Alternatively, as Figure 31 As shown, the pitch curve of the rack 7 also includes a fourth arc segment A8A9, which is connected to the end of the second straight line segment A7A8 away from the third arc segment A6A7, the tangent of the starting end of the fourth arc segment A8A9 coincides with the second straight line segment A7A8, and the curvature center O4 of the fourth arc segment A8A9 is located on the side of the rack 7 toward or away from the gear 61.

[0137] 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 on the rack 7 corresponding to the third arc segment A6A7 is the sixth tooth segment 716 .

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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 .

[0143] 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.

[0144] 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.

[0145] Optionally, the connecting rod is further provided with a second guide portion, and the guide member 84 is provided with a second guide matching portion. When the first guide portion 72 is in the separated position, the second guide portion and the second guide matching portion cooperate to guide the movement of the connecting rod.

[0146] When the first guide portion 72 and the first guide matching portion 81 are separated, that is, when the first guide portion 72 is in the separated position, the second guide portion and the second guide matching portion cooperate to guide the movement of the connecting rod so that the connecting rod can move along a preset trajectory and prevent the movement of the connecting rod from deviating from the preset trajectory.

[0147] The shape of the first guide groove 811 needs to be determined according to the motion trajectory of the connecting rod and the forms of the second guide portion and the second guide matching portion.

[0148] In a specific embodiment, the first guide groove 811 includes straight segments and / or curved segments, for example Figure 17 As shown, the first guide groove 811 is in the form of a broken line. It is understood that the first guide groove 811 can also be in a non-broken line form, for example, an arc shape. When moving from the closed position to the small encircling air supply position, the first guide post 721 is located in the first guide groove 811 and can slide relative to the first guide groove 811. After moving from the small encircling air supply position, the first guide post 721 is released from the first guide groove 811.

[0149] Optionally, the first guide portion 72 is in the guiding position, that is, when the first guide portion 72 cooperates with the first guide matching portion 81 , the second guide portion cooperates with the second guide matching portion.

[0150] In this way, when the first guide portion 72 is in the guiding position, the cooperation between the first guide portion 72 and the first guide matching portion 81, and the cooperation between the second guide portion and the second guide matching portion jointly guide the movement of the connecting rod, thereby improving the stability of the connecting rod movement, and some movement forms of the connecting rod cannot be achieved by relying on the cooperation between a single guide portion and a guide matching portion. For example, when the connecting rod rotates in a plane, the cooperation between the first guide portion 72 and the first guide matching portion 81, and the cooperation between the second guide portion and the second guide matching portion realizes the cooperation between multiple guide portions and guide matching portions, which can realize more diversified movement forms of the connecting rod, making the movement forms of the connecting rod more selective.

[0151] During the entire opening process of the air deflector 2, as shown in FIG. Figures 10 to 30 As shown, the second guide portion and the second guide matching portion are always matched, or the second guide portion and the second guide matching portion can be switched between a matched state and a non-matched state.

[0152] Optionally, the second guide portion includes a first sub-guide portion 74 and a second sub-guide portion 75, and the second guide mating portion includes a first sub-guide mating portion for mating with the first sub-guide portion 74 and a second sub-guide mating portion for mating 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.

[0153] The guide member 84 is fixed to the housing 1. For example, the guide member 84 includes a mechanism box, which includes a body 84 and a cover 85 that interlock with each other. A connecting rod is disposed within the mechanism box, located between the body 84 and the cover 85. The connecting rod moves between a retracted position within the mechanism box and an extended position extending out of the mechanism box. When the connecting rod extends out of the mechanism box, it drives the air deflector 2 to move.

[0154] The first sub-guide portion 74 and the second sub-guide portion 75 are arranged on the same side of the connecting rod, and the first sub-guide matching portion and the second sub-guide matching portion are arranged on the box body 84. The first sub-guide portion 74 and the first sub-guide matching portion match each other, and the second sub-guide portion 75 and the second sub-guide matching portion match each other, so that the connecting rod movement is stable.

[0155] In a specific embodiment, Figure 3 and Figure 4 As shown, the first sub-guide portion 74 includes a first sub-guide groove 78, the first sub-guide matching portion includes a first sub-guide column 82, the second sub-guide portion 75 includes a second sub-guide column 751, the second sub-guide matching portion includes a second sub-guide groove 83, the first sub-guide column 82 is slidably connected to the first sub-guide groove 78, and the second sub-guide column 751 is slidably connected to the second sub-guide groove 83.

[0156] In another specific embodiment, the first sub-guide portion 74 includes a first sub-guide column 82, the first sub-guide matching portion includes a first sub-guide groove 78, the second sub-guide portion 75 includes a second sub-guide groove 83, the second sub-guide matching portion includes a second sub-guide column 751, the first sub-guide column 82 is slidably connected to the first sub-guide groove 78, and the second sub-guide column 751 is slidably connected to the second sub-guide groove 83.

[0157] The first sub-guide column 82 is slidably connected to the first sub-guide groove 78, which 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 second sub-guide column 751 is slidably connected to the second sub-guide groove 83, which 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.

[0158] When the first sub-guide portion 74 includes a first sub-guide groove 78, the second sub-guide portion 75 includes a second sub-guide column 751; when the first sub-guide portion 74 includes a first sub-guide column 82, the second sub-guide portion 75 includes a second sub-guide groove 83, so as to avoid the first sub-guide portion 74 and the second sub-guide portion 75 being in the form of grooves or columns. In this way, the space of the connecting rod can be more reasonably utilized, the connecting rod structure can be compact, and the connecting rod or the box body 84 can be avoided from being too large.

[0159] The shapes of the first sub-guide groove 78 and the second sub-guide groove 83 need to be determined according to the motion trajectory of the connecting rod, the forms of the first guide portion 72 and the first guide matching portion 81 .

[0160] The first sub-guide groove 78 includes straight segments and / or curved segments. The first guide groove 811 extends along the length direction of the connecting rod. 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 connected straight segments and / or curved segments, such as Figure 4 and Figure 13 As shown, from the closed position to the small encircling air supply position, the first sub-guide column 82 is located in the first guide section 781 and can slide relative to the first guide section 781; the first sub-guide groove 78 also includes a second guide section 782; from the small encircling air supply position to the large encircling air supply position, as shown Figure 18 As shown, the first sub-guide column 82 is located in the second guide section 782 and can slide relative to the second guide section 782. The second guide section 782 is curved, such as arc-shaped; Figure 20 As shown, the first sub-guide groove 78 also includes a third guide segment 783. From the large encircling air supply position to the heating down-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. The third guide segment 783 includes a curved segment and / or a straight segment; as shown Figure 23 As shown, the first sub-guide groove 78 also includes a fourth guide section 784. From the heating down-blowing position to the maximum air supply position, the first sub-guide column 82 is located in the fourth guide section 784 and can slide relative to the fourth guide section 784. The fourth guide section 784 includes a curved section and / or a straight section, for example, in a curved shape.

[0161] The second sub-guide groove 83 includes a straight line segment and / or a curved line segment. The second sub-guide groove 83 includes 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 includes a straight line segment and / or a curved line segment, such as Figure 3 and Figure 12 As shown, from the closed position to the small encircling 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 includes a first sub-segment 8311 and a second sub-segment 8314. The first sub-segment 8311 includes 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 connected to the first sub-segment 8311. The connection point is located between the first end 8312 and the second end 8313. The air guide plate 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. Figure 12 As shown, in the cooling upward position, the second sub-guide column 751 moves to the second end; Figure 17 As shown, from the cooling upward position to the small encircling air supply position, the second end 8313 slides in the opposite direction (i.e., from the second end toward the first end), and when it slides to the connection between the first sub-segment 8311 and the second sub-segment 8314, it slides into the second sub-segment 8314. The first sub-segment 8311 is curved, and the second sub-segment 8314 is straight. The connection between the second sub-segment 8314 and the first sub-segment 8311 forms a first angle 8315, and the second sub-guide column 751 moves to the first sub-segment 8311 and the second sub-segment 8314. 14, since the size of the connection between 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 between the second sub-guide column 751 and the connection has a weaker limiting effect on the connecting rod and plays an auxiliary role; from the small encircling air supply position to the large encircling 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, and the connection between the sixth guide segment 833 and the second sub-segment 8314 forms a second angle 832, as shown in FIG. Figure 17 As shown, in the small encircling air supply position, the second sub-guide column 751 is located at the second corner 832, and the sixth guide section 833 is arc-shaped, for example, circular arc-shaped; Figure 26As shown, from the large-encircling air supply position to the heating down-blowing 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. During the opening process of the air guide plate 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 and the sixth guide segment 833 are located in the same arc shape, the fourth sub-segment 8342 is a straight line, and the connection between the fourth sub-segment 8342 and the third sub-segment 8341 forms a third angle 8343; as shown Figure 26 As shown, from the heating downward blowing 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. The connection between the eighth guide segment 835 and the fourth sub-segment 8342 forms a fourth corner 8344. In the heating downward blowing position, the second sub-guide column 751 is located at the fourth corner 8344.

[0162] Alternatively, as Figure 6 As shown, the second guide portion includes a first sub-guide portion 74 and a third sub-guide portion 76, and the second guide matching portion includes a first sub-guide matching portion for matching with the first sub-guide portion 74 and a third sub-guide matching portion 86 for matching with the third sub-guide portion 76; wherein, the first sub-guide portion 74 and the third sub-guide portion 76 are located on opposite sides of the connecting rod.

[0163] The first sub-guide portion 74 and the third sub-guide portion 76 are respectively provided on the opposite sides of the connecting rod, so that the movement of the connecting rod on the opposite sides can be guided respectively, making the movement of the connecting rod more stable, and can reasonably utilize the space of the connecting rod, avoiding the first sub-guide portion 74 and the third sub-guide portion 76 being provided on the same side of the connecting rod, resulting in the connecting rod being too large.

[0164] The third sub-guide fitting portion 86 is disposed on the box cover 85 .

[0165] Optionally, one of the first sub-guide portion 74 and the first sub-guide matching portion includes a first sub-guide post 82, and the other includes a first sub-guide slot 78, and the first sub-guide post 82 is slidably connected to the first sub-guide slot 78; Figure 6 As shown, one of the third sub-guide portion 76 and the third sub-guide matching portion 86 includes a third sub-guide column 861 , and the other includes a third sub-guide slot 77 , and the third sub-guide column 861 is slidably connected to the third sub-guide slot 77 .

[0166] The third sub-guide column 861 is adapted to the third sub-guide groove 77. When the third sub-guide column 861 is matched with the third sub-guide groove 77, the third sub-guide column 861 is located in the third sub-guide groove 77 and can slide relative to the third sub-guide groove 77 to guide the movement of the connecting rod; when the third sub-guide column 861 is not matched with the third sub-guide groove 77, the third sub-guide column 861 is located outside the third sub-guide groove 77 and has no guiding effect on the movement of the connecting rod.

[0167] The third sub-guide groove 77 includes a straight line segment and / or a curved line segment. The third sub-guide groove 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. Figure 6 、 Figure 14 and Figure 15 As shown, when the air guide plate 2 moves from the closed position to the small encircling 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, it cooperates with the ninth guide segment 771. The ninth guide segment 771 includes a fifth sub-segment 7711 and a sixth sub-segment 7712. The connection between the fifth sub-segment 7711 and the sixth sub-segment 7712 forms a fifth angle 7713. In the process of the air guide plate 2 opening from the closed position to the cooling upward position, the third sub-guide column 861 cooperates with the fifth sub-segment 7711, as shown in FIG. Figure 14 As shown, in the cooling upward position, the third sub-guide column 861 is located at the fifth corner 7713. When opened from the cooling upward position to the small encircling air supply position, the third sub-guide column 861 cooperates with the sixth sub-segment 7712. The fifth sub-segment 7711 includes a straight segment and / or a curved segment, and the sixth sub-segment 7712 includes a straight segment and / or a curved segment; as shown Figure 22 As shown, when the air guide plate 2 moves from the small encircling air supply position to the large encircling 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, it cooperates with the tenth guide segment 772, and the connection between the ninth guide segment 771 and the tenth guide segment 772 forms a sixth angle 775, as shown in FIG. Figure 15 As shown, in the small encircling air supply position, the third sub-guide column 861 is located at the sixth corner 775, and the tenth guide segment 772 includes a straight segment and / or a curved segment, for example, in an arc shape; Figure 24 As shown, when the air guide plate 2 moves from the large encircling 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, it cooperates with the eleventh guide segment 773. The eleventh guide segment 773 includes a straight segment and / or a curved segment, for example, in a curved shape; 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.

[0168] 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.

[0169] 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.

[0170] 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 .

[0171] 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.

[0172] The drive component 53 can be a motor, which is directly connected to the first connecting rod 5 or connected via a transmission member such as a gear 61. The drive component 53 drives the first connecting rod 5, which in turn drives the guide plate 3. The movement of the guide plate 3 drives the second connecting rod 54 relative to the housing 1. The provision of the second connecting rod 54 not only enhances the stability of the guide plate 3 but also cooperates with the first connecting rod 5 to achieve the desired air guide position of the guide plate 3.

[0173] Along the direction from the guide plate 3 to the wind guide plate 2, the first connection part 31 and the second connection part 32 are arranged in sequence, that is, the distance between the first connection part 31 and the wind guide plate 2 is greater than the distance between the second connection part 32 and the wind guide plate 2, so that the guide plate 3 can move toward the direction of the wind guide plate 2 and cooperate with the wind guide plate 2 to achieve the target wind guiding form.

[0174] like Figure 12 and Figure 19 As shown, the guide plate 3 is flipped toward the air guide plate 2 to open the second air outlet area 112, thereby jointly realizing the cooling upward air supply mode and the large-scale surrounding air supply mode.

[0175] There is no driving connection between the driving component 53 and the second connecting rod 54 , that is, the movement of the second connecting rod 54 is directly driven by the guide plate 3 , not by the driving component 53 .

[0176] like Figure 20 As shown, the box body 84 is provided with an escape space 41 , and the driving component 53 , the first connecting rod 5 and the second connecting rod 54 are all provided outside the box body 84 and located in the escape space 41 .

[0177] The opening range of the guide plate 3 is smaller than that of the air guide plate 2. Therefore, the lengths of the first connecting rod 5 and the second connecting rod 54 are smaller. In order to realize the driving of the guide plate 3 by the first connecting rod 5 and the second connecting rod 54, the avoidance space 41 is provided on the side of the box body 84 facing the first air outlet area 111.

[0178] Alternatively, as Figure 22 As shown, the distance between the first connection portion 31 and the middle portion of the guide plate 3 in the width direction is smaller than the distance between the second connection portion 32 and the middle portion of the guide plate 3 in the width direction.

[0179] In this way, the length of the movement trajectory of the first connecting rod 5 can be shortened, and the space occupied by the first connecting rod 5 can be reduced.

[0180] Alternatively, as 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.

[0181] The first connection portion 31 includes a mounting protrusion on the inner wall surface of the guide plate 3 .

[0182] 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 .

[0183] 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.

[0184] 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.

[0185] 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.

[0186] 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.

[0187] 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 .

[0188] 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 .

[0189] During the movement of the guide plate 3, the first connecting rod 5 plays the role of providing power, driving 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 is more of a rotation point for the movement of the guide plate 3. Therefore, during the opening process of the guide plate 3, 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.

[0190] 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 a first sub-rod 51 and a 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.

[0191] Alternatively, as Figure 3 As shown, the inner wall surface of the air guide plate 2 is provided with an avoidance groove 21. When the air guide plate 2 and the guide plate 3 close the first air outlet area 111 and the second air outlet area 112 respectively, that is, when the air guide plate 2 and the guide plate 3 are both in the closed position, the end of the guide plate 3 close to the air guide plate 2 is inserted into the avoidance groove 21.

[0192] When the air guide plate 2 and the guide plate 3 are both in the closed position, the end of the guide plate 3 close to the air guide plate 2 is inserted into the avoidance groove 21, so that the guide plate 3 and the air guide plate 2 partially overlap, avoiding the formation of a gap between the air guide plate 2 and the guide plate 3, thereby enhancing the aesthetics of the indoor unit.

[0193] In this way, when opening the air outlet, if the air guide plate 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 guide plate 2 needs to move first, and after the air guide plate 2 leaves the second air outlet area 112, the guide plate 3 will open again; when closing the air outlet, the guide plate 3 will first close the second air outlet area 112, and then the air guide plate 2 will close the first air outlet area 111.

[0194] An embodiment of the second aspect of the present application provides an air conditioner, including an indoor unit, the indoor unit including an air guide plate 2 and a driving device for the air guide plate 2 of the air conditioner as described in any one of the above embodiments, and the rack 7 is connected to the air guide plate 2.

[0195] The air conditioner provided in the embodiment of the second aspect of the present application includes a driving device for the air-conditioning air guide plate 2 as described in any one of the above embodiments, and thus has all the beneficial effects of the driving device for the air-conditioning air guide plate 2 as described in any one of the above embodiments, which will not be repeated here.
