Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

The following disclosure provides many different embodiments, or examples, for implementing different features of the utility model. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Hereinafter, an air conditioning indoor unit 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 3 to 6, the air conditioning indoor unit 100 includes a casing 1, the casing 1 is formed with a mounting opening 10, and an outlet 10a is defined in the mounting opening 10, that is, the outer contour of the outlet 10a does not exceed the outer contour of the mounting opening 10. For example, the outer contour of the air outlet 10a is located in the outer contour of the mounting opening 10, and at this time, the edge of the air outlet 10a and the edge of the mounting opening 10 are arranged at intervals, so that the edge of the mounting opening 10 does not participate in defining the air outlet 10 a; or, a part of the outer contour of the air outlet 10a is located in the outer contour of the mounting port 10, and another part of the outer contour of the air outlet 10a is overlapped with the outer contour of the mounting port 10, at this time, a part of the edge of the air outlet 10a is arranged at an interval with the corresponding edge of the mounting port 10, and another part of the edge of the air outlet 10a is overlapped with the corresponding edge of the mounting port 10, so that a part of the edge of the mounting port 10 participates in defining the air outlet 10 a; or, the outer contour of the air outlet 10a coincides with the outer contour of the mounting opening 10, that is, the edge of the air outlet 10a coincides with the corresponding edge of the mounting opening 10, so that the mounting opening 10 is the air outlet 10 a.

The indoor unit 100 further includes a wind deflector 2, and the wind deflector 2 is movably disposed at the outlet 10a to facilitate the wind deflector 2 to close or open the outlet 10 a. The air deflector 2 has a connecting portion 20.

As shown in fig. 4, 7, 12, 14 and 19, the air conditioning indoor unit 100 further includes a driving assembly 3, the driving assembly 3 includes a driving arm 31 and a first driving mechanism 32, the driving arm 31 is connected between the first driving mechanism 32 and the connecting portion 20, and the driving arm 31 is driven by the first driving mechanism 32 to move to push away or pull close to the connecting portion 20, then the first driving mechanism 32 is used to drive the driving arm 31 to move, so that the driving arm 31 can push away from the connecting portion 20 in a direction away from the central axis 1a of the cabinet 1 and can also pull close to the connecting portion 20 in a direction close to the central axis 1a of the cabinet 1, so as to change a distance between the connecting portion 20 and the central axis 1a of the cabinet 1, thereby changing a distance between the air deflector 2 and the central axis 1a of the cabinet 1.

The driving arm 31 has a first position and a second position, and a distance between the connecting portion 20 and the central axis 1a of the casing 1 when the driving arm 31 is at the first position is smaller than a distance between the connecting portion 20 and the central axis 1a of the casing 1 when the driving arm 31 is at the second position, so that the air deflector 2 closes the air outlet 10a at the first position (as shown in fig. 2 and 4), and the air deflector 2 opens the air outlet 10a at the second position (as shown in fig. 12 and 14). When the driving arm 31 moves from the first position to the second position, the driving arm 31 pushes away the connecting portion 20 toward a direction away from the central axis 1a of the casing 1 to increase a distance between the connecting portion 20 and the central axis 1a of the casing 1, so that when the driving arm 31 moves to the second position, the air deflector 2 has a suitable distance from the air outlet 10a to open the air outlet 10 a; when the driving arm 31 moves from the second position to the first position, the driving arm 31 draws the connecting portion 20 toward a direction close to the central axis 1a of the casing 1, so as to reduce a distance between the connecting portion 20 and the central axis 1a of the casing 1, so that when the driving arm 31 moves to the first position, the air guiding plate 2 can close the air outlet 10 a.

Wherein, the driving arm 31 has a central line 31a, the central line 31a extends along the length direction of the driving arm 31, the central line 31a of the driving arm 31 at the first position intersects with the central line 31a at the second position at a non-zero included angle (as shown in fig. 4 and 12), so that in the process that the driving arm 31 moves from the first position to the second position or from the second position to the first position, not only the distance of the driving arm 31 (or the connecting part 20) relative to the central axis 1a of the casing 1 is changed, but also the placing posture of the driving arm 31 relative to the central axis 1a of the casing 1 is changed, thereby the position of the air deflector 2 relative to the air outlet 10a can be adjusted more flexibly, the air guiding position and the air guiding angle of the air deflector 2 are enriched, and the air guiding position and the air guiding angle of the air deflector 2 are adjusted more easily, the air supply range of the indoor unit 100 of the air conditioner can be enlarged, so that the actual differentiation requirement can be better met.

Hereinafter, the outlet 10a is formed at the front side of the housing 1, and the outlet 10a extends in the vertical direction, for example, and it will be easily understood by those skilled in the art that the outlet 10a is formed at another position and the outlet 10a extends in another direction after reading the following technical solutions.

As shown in fig. 2 and 4, in the first position, the center line 31a of the driving arm 31 extends horizontally in the front-rear direction; as shown in fig. 12 and 14, in the second position, the central line 31a of the driving arm 31 is horizontally disposed and extends obliquely with respect to the front-back direction, and at this time, the air deflector 2 can open the air outlet 10a under the driving of the driving arm 31, so as to guide the airflow at the air outlet 10a to at least one of two sides of the width of the air deflector 2, that is, to guide the airflow at the air outlet 10a to the left side and/or the right side of the air deflector 2, so that the air conditioning indoor unit 100 has a suitable air supply range.

More specifically, in the second position, if the center line 31a of the driving arm 31 extends from the left rear side toward the right front side, the air deflector 2 may guide the air flow at the air outlet 10a to the left side of the air deflector 2, or the air deflector 2 may guide the air flow at the air outlet 10a to the left and right sides of the air deflector 2; in the second position, if the center line 31a of the driving arm 31 extends from the right rear side to the left front side, the air deflector 2 can guide the air flow at the air outlet 10a to the right side of the air deflector 2, or the air deflector 2 can guide the air flow at the air outlet 10a to the left and right sides of the air deflector 2.

It can be understood that, in the second position, if the air deflector 2 guides the airflow at the air outlet 10a to one side of the width of the air deflector 2, the lateral remote air supply of the indoor unit 100 of the air conditioner is facilitated; when the air guide plate 2 is in the second position, if the air guide plate 2 guides the air flow at the air outlet 10a to two sides of the width of the air guide plate 2, the air outlet difference at two sides of the width of the air guide plate 2 can be realized, so that the air outlet amount at two sides of the width of the air guide plate 2 is different, and the actual requirement can be better met.

According to the air-conditioning indoor unit 100 of the embodiment of the utility model, the driving arm 31 is provided with the first position and the second position, and the center line 31a of the driving arm 31 at the first position and the center line 31a at the second position are intersected to form a non-zero included angle, so that the air guide position and the air guide angle of the air deflector 2 relative to the air outlet 10a can be more flexibly adjusted, the air supply range of the air-conditioning indoor unit 100 can be favorably enlarged, and the actual differentiation requirement can be better met.

Alternatively, in the example of fig. 2, 8, 21 and 22, the driving arm 31 extends along a straight line, the central line 31a of the driving arm 31 is a straight line, and the included angle between the central line 31a of the driving arm 31 at the first position and the central line 31a at the second position may be an acute angle, for example, the included angle may be set in a range of 0 ° to 80 °, but is not limited thereto.

In some embodiments of the present invention, as shown in fig. 21 and 22, and fig. 26 to 30, the first driving mechanism 32 includes a first driver 321, a driving member 322, and a limiting member 323, the driving member 322 is pivotally connected to the driving arm 31, the driving member 322 is driven by the first driver 321 to move along a curve, so that the driving member 322 drives the driving arm 31 to push away from or pull toward the connection portion 20, the limiting member 323 and the driving member 322 are disposed at a distance from each other along a length direction of the driving arm 31, the limiting member 323 and the driving arm 31 slidably engage along the length direction of the driving arm 31, and the driving arm 31 can rotate around a central axis 323a of the limiting member 323. The driving member 322 is perpendicular to the longitudinal direction of the driving arm 31 with respect to the rotation axis 322a of the driving arm 31.

Obviously, when the driving arm 31 is driven by the driving member 322 to move along a curve, due to the limiting effect of the limiting member 323, in the process that the driving arm 31 is pushed away from or pulled close to the connecting portion 20, the driving arm 31 rotates relative to the central axis 323a of the limiting member 323 to swing the driving arm 31, so as to drive the connecting portion 20 to swing, and thus, the flexible adjustment of the air deflector 2 is realized; meanwhile, the driving member 322 can rotate relative to the driving arm 31, so that when the driving member 322 drives the driving arm 31 to move, interference and jamming between the driving member 322 and the driving arm 31 cannot occur. Obviously, the air conditioner indoor unit 100 of the present application has a simple and compact structure, high installation efficiency, and good reliability in use.

The motion track of the driving member 322 may include an arc line, an elliptical arc line, etc., and it is only necessary to ensure that the motion track of the driving member 322 is a non-straight line, so as to ensure that the center line 31a of the driving arm 31 at the second position intersects with the center line 31a at the first position at a non-zero included angle.

It can be understood that the driving arm 31 can rotate around the central axis 323a of the limiting member 323, and includes the following solutions: 1. the driving arm 31 is rotatably engaged with the limiting member 323, so that when the driving arm 31 slides relative to the limiting member 323, the driving arm 31 may further have a degree of freedom of rotation relative to the limiting member 323, and at this time, the limiting member 323 may be fixedly disposed relative to the housing 1; 2. the limiting member 313 is rotatably disposed on the housing 1, and the driving arm 31 can only slidably engage with the limiting member 323 in the length direction of the driving arm 31, so that the driving arm 31 can have a degree of freedom of rotation relative to the housing 1; 3. the limiting member 313 is rotatably disposed on the housing 1, and the driving arm 31 is rotatably engaged with the limiting member 323, so that the driving arm 31 can rotate relative to the housing 1.

Alternatively, in the example of fig. 22, the limiting element 323 is located between the driving element 322 and the connection portion 20, and the swing positions of the portions of the driving arm 31 located on opposite sides of the limiting element 323 are substantially opposite, that is, the moving direction of the driving element 322 is substantially opposite to the moving direction of the connection portion 20, for example, when the driving element 322 swings left along a curve, the connection portion 20 swings right, and the driving element 322 swings right along a curve, and the connection portion 20 swings left, so that the air-conditioning indoor unit 100 can blow air laterally on either side of the width of the air outlet 10 a.

Optionally, the limiting member 323 may be disposed in the middle of the air outlet 10a in the width direction, so that the air deflector 2 can be adjusted only by one driving arm 31 in the width direction of the air deflector 2, which is beneficial to simplifying the structure of the driving assembly 3 and reducing the cost.

Of course, the position setting of the stopper 323 is not limited thereto; for example, in the length direction of the driving arm 31, the driving element 322 may be located between the limiting element 323 and the connecting portion 20, and the moving direction of the driving element 322 is substantially the same as the moving direction of the connecting portion 20, for example, when the driving element 322 swings left along a curve, the connecting portion 20 swings left, and when the driving element 322 swings right along a curve, the connecting portion 20 swings right, which is also convenient for realizing the lateral air supply of the air conditioning indoor unit 200 on either side of the width of the air outlet 10 a.

As shown in fig. 22, the limiting member 323 may be a limiting column, and the driving arm 31 is formed with a sliding groove 31d slidably engaged with the limiting member 323, and the sliding groove 31d extends along the longitudinal direction of the driving arm 31.

In some embodiments of the present invention, as shown in fig. 21 and 22, the first driver 321 includes a first motor 3211, a gear 3212, and a rack 3213, the gear 3212 is connected to the first motor 3211, the rack 3213 extends along a curve, for example, the rack 3213 extends in an open loop or a closed loop, the rack 3213 is fixedly connected to the driving member 322, and a central axis of the rack 3213 is parallel to a rotation axis 322a of the driving member 322, so as to prevent the driving member 322 from being jammed with the driving arm 31 during the driving of the driving arm 31 by the rack 3213 through the driving member 322, so as to ensure smooth movement of the driving arm 31, and the first driver 321 has a simple structure and operates smoothly.

Alternatively, in the example of fig. 21, the rack 3213 is circular, and the motion track of the driving member 322 may be an arc line or a circle, so as to simplify the motion mode of the driving member 322 on the premise of ensuring the flexible adjustment of the air deflector 2.

For example, as shown in fig. 26 and 29, when the driving arm 31 is at the first position, the central line 31a of the driving arm 31 extends in the front-rear direction, and the driving member 322, the limiting member 323, and the connecting portion 20 may be disposed opposite to each other in the front-rear direction; the driving member 322 can move leftwards or rightwards to realize the swinging of the wind deflector 2 leftwards or rightwards.

It can be understood that, when the movement locus of the driving member 322 is a circle or a circular arc line, and the central angle corresponding to the circle or the circular arc line is larger, the driving arm 31 may further have a third position (as shown in fig. 7 and 8), when the driving arm 31 is at the third position, the distance between the connecting portion 20 and the central axis 1a of the casing 1 is larger than the distance between the connecting portion 20 and the central axis 1a of the casing 1 when the driving arm 31 is at the second position, so that in the third position, the air deflector 2 opens the air outlet 10a and guides the air flow at the air outlet 10a to both sides of the width of the air deflector 2, at this time, the first position of the driving arm 31 moves to the second position and then to the third position, in this process, the central angle of the circular arc section corresponding to the driving member 322 may be 180 °, and any position between the first position and the third position is the second position.

Of course, the structure of the first driver 321 is not limited thereto; for example, the first driver 321 may be further configured to include a first motor 3211 and a driving wheel, a central axis of the driving wheel is parallel to the driving member 322 with respect to the rotation axis 322a of the driving arm 31, the driving member 322 is spaced apart from the central axis of the driving wheel, and the driving member 322 is pivotally connected to the driving wheel, so that the first motor 3211 drives the driving wheel to rotate, and the driving member 322 can also move along a curve.

In some embodiments of the present invention, as shown in fig. 21 and 22, the air conditioning indoor unit 100 further includes a first guide 4, and the first guide 4 is configured to guide the movement of the rack 3213, so that the first guide 4 can perform a certain limiting and guiding function on the movement of the rack 3213 to ensure that the rack 3213 moves along a preset track, thereby ensuring that the driving element 322 moves along a curve.

For example, the first guide 4 includes a first guide plate 41, the first guide plate 41 is formed with a first guide portion 411, and the rack 3213 is slidably fitted to the first guide portion 411 to ensure smooth movement of the rack 3213. The first guiding portion 411 is a guide rail or a guide groove, and the first guiding portion 411 has a simple structure and is flexible to set.

In some embodiments of the present invention, as shown in fig. 21 and 22, the air conditioning indoor unit 100 further includes a second guiding element 5, and the second guiding element 5 is used for guiding the movement of the driving element 322, so that the second guiding element 5 can play a certain role in limiting and guiding the movement of the driving element 322, and further ensure that the driving element 322 moves along a curve.

For example, the second guide member 5 includes a second guide plate 51, the second guide plate 51 is formed with a second guide portion 511, and the driving member 322 is slidably fitted to the second guide portion 511 to ensure smooth movement of the driving member 322. The second guiding portion 511 is a guide rail or a guide groove, and the second guiding portion 511 has a simple structure and is flexible to set.

For example, in the example of fig. 21, 22, and 25, the air conditioning indoor unit 100 includes the first guide member 4 and the second guide member 5, the first guide member 4 includes the first guide plate 41, the second guide member 5 includes the second guide plate 51, the first guide plate 41 and the second guide plate 51 are connected to define the accommodation space together, and the driving arm 31, the driving member 322, and the limiting member 323 are provided in the accommodation space. When the first driver 321 includes the first motor 3211, the gear 3212, and the rack 3213, the gear 3212 and the rack 3213 are both disposed in the accommodating space, and the first motor 3211 is fixedly disposed on the first guide plate 41.

In addition, a mounting plate 6 may be further disposed between the first guide 4 and the second guide 5, the rack 3213 is fitted between the first guide 4 and the mounting plate 6, the limiting member 323 is fixedly disposed on a side of the mounting plate 6 away from the first guide 4, the driving arm 31 is disposed between the second guide 5 and the mounting plate 6, a through hole 6a is formed in the mounting plate 6, and the driving member 322 is fixedly connected to the rack 3213 through the through hole 6 a.

Of course, the second guide 5 may also be used to support parts of the drive assembly 3, not to guide the movement of the drive member 322. The mounting plate 6 may not be provided between the first guide 4 and the second guide 5.

In some embodiments of the present invention, as shown in fig. 7 and 8, in the second position, the air deflector 2 guides the airflow at the air outlet 10a to one side of the width of the air deflector 2, so as to facilitate lateral remote air supply of the indoor unit 100 of the air conditioner (for example, when the width of the air deflector 2 is large); the driving arm 31 further has a third position, and when the driving arm 31 is at the second position, the distance between the connecting portion 20 and the central axis 1a of the casing 1 is smaller than the distance between the connecting portion 20 and the central axis 1a of the casing 1 when the driving arm 31 is at the third position, so that in the third position, the air deflector 2 opens the air outlet 10a, and guides the airflow at the air outlet 10a to two sides of the width of the air deflector 2, which is convenient for realizing the air outlet from two sides of the air conditioning indoor unit 100, and at this time, no air outlet is located in the middle of the air outlet 10a, so that the air conditioning indoor unit 100 can be prevented from blowing out directly to a user. In addition, by providing the driving arm 31 with the third position, the gap between the air deflector 2 and the air outlet 10a is relatively large, so as to ensure the air outlet area of the indoor unit 100 of the air conditioner.

Alternatively, in the example of fig. 4, 7, and 22, the drive arm 31 extends along a straight line, the center line 31 of the drive arm 31 is a straight line, the center line 31a of the drive arm 31 at the third position coincides with the center line 31a at the first position, that is, the placement posture of the drive arm 31 at the third position is the same as the placement posture at the first position, and the drive arm 31 is pushed away from the connecting portion 20 with respect to the first position at the third position, facilitating simplification of the structure of the drive arm 31, while facilitating simplification of the structure of the first drive mechanism 32.

For example, when the driving arm 31 is located at the second position, the air guiding plate 2 may be driven by the driving arm 31 to deflect towards one side of the width of the air outlet 10a, and the air guiding plate 2 may abut against the one side of the width of the air outlet 10a, so that an air outlet duct is defined between the air guiding plate 2 and the other side of the width of the air outlet 10 a. When the driving arm 31 is located at the third position, the air deflector 2 is driven by the driving arm 31 to be placed in the same posture as that of the air deflector 2 when the driver is located at the first position, and at this time, the air deflector 2 and the air on both sides of the width of the air outlet 10a define an air outlet duct, so that the air flow at the air outlet 10a is guided to both sides of the width of the air deflector 2.

For example, in the example of fig. 7, the air outlet 10a is formed at the front side of the casing 1, when a user uses the indoor unit 100, the user is usually located at the front side of the indoor unit 100, and at this time, the driving arm 31 may move to the third position so that the air deflector 2 guides the air flow at the air outlet 10a to the left and right sides, so as to prevent the air flow at the air outlet 10a from directly blowing to the user, which is beneficial to improve comfort.

In some embodiments of the present invention, as shown in fig. 7 and 8, the driving arm 31 is pivotally connected to the connecting portion 20, so that the connecting portion 20 can rotate relative to the driving arm 31 to change the wind guiding direction of the wind deflector 2, and the wind deflector 2 can rotate relative to the driving arm 31, thereby further enriching the wind guiding angle of the wind deflector 2, enriching the wind blowing mode and the wind blowing range of the indoor air conditioner 100, and facilitating to improve the applicability of the indoor air conditioner 100.

For example, when the driving arm 31 is located at the second position, the air deflector 2 may deflect towards the width side of the air outlet 10a under the driving of the driving arm 31, and if the air outlet duct is defined by the air deflector 2 and the width side of the air outlet 10a, the air deflector 2 may be rotated towards the width side of the air outlet 10a to stop the air deflector 2 and the width side of the air outlet 10a, so as to realize the lateral remote air supply of the indoor unit 100 of the air conditioner; it is of course also possible to rotate the air deflection plate 2 to other angular positions. Therefore, the design cost of the engagement manner between the driving arm 31, the air guide plate 2, and the air outlet 10a can be reduced, which is advantageous for simplifying the design of the indoor unit 100 of the air conditioner.

Of course, the present application is not so limited; for example, the driving arm 31 may also be fixedly connected to the connecting portion 20, and the air deflector 2 may be configured to: when the driving arm 31 is located at the second position, the air deflector 2 is driven by the driving arm 31 to abut against one side of the width of the air outlet 10a, and an air outlet duct is defined by the air deflector 2 and the other side of the width of the air outlet 10a, so that lateral remote air supply of the indoor air conditioner 100 can be realized.

For example, as shown in fig. 4 and 7, when the driving arm 31 is located at the third position, the air deflector 2 is driven by the driving arm 31 to be placed in the same posture as that of the air deflector 2 when the driver is located at the first position, the air deflector 2 can guide the airflow at the air outlet 10a to both sides of the width of the air deflector 2, and at this time, the air deflector 2 can rotate relative to the driving arm 31 to change the air guiding angle of the air deflector 2, so that the air conditioning indoor unit 100 has a proper air supply range and air supply angle.

Alternatively, the rotation angle of the wind deflector 2 relative to the driving arm 31 can be set according to actual requirements, for example, the wind deflector 2 can rotate 360 ° relative to the driving arm 31 (including a rotation of approximately 360 °), or rotate 270 °, or rotate 180 °, or rotate 150 °, and so on. For example, in the example of fig. 7 and 8, when the driving arm 31 is located at the third position, the connecting portion 20 is located at a relatively long distance from the central axis 1a of the casing 1, so as to provide a sufficient rotation space for the air guiding plate 2, and the air guiding plate 2 can be configured to rotate at an angle close to 360 ° with respect to the driving arm 31, so that the air guiding plate 2 can better adapt to users at different positions, and thus users can avoid the wind from the wind outlet 10a from directly blowing on the users at different positions.

In some embodiments of the present invention, as shown in fig. 4 and 7, the air deflector 2 has a first air guiding position, in which the air deflector 2 closes the air outlet 10a if the driving arm 31 is located at the first position, and if the driving arm 31 is away from the first position, the air deflector 2 guides the air flow at the air outlet 10a to both sides of the width of the air deflector 2,

as shown in fig. 12 and 14, the air deflector 2 further has a second air guiding position, and in the second air guiding position, if the driving arm 31 is away from the first position, the air deflector 2 guides the air flow at the air outlet 10a to one side of the width of the air deflector 2, so as to realize the lateral remote air supply of the indoor unit 100 of the air conditioner. Therefore, the air guide plate 2 is provided with the first air guide position and the second air guide position, so that the adjustment flexibility of the air guide plate 2 is further improved.

In some embodiments of the present invention, as shown in fig. 25, the driving assembly 3 further includes a second driving mechanism 33, and the second driving mechanism 33 is configured to drive the connecting portion 20 to rotate relative to the driving arm 31, so that the rotation of the air deflector 2 relative to the driving arm 31 can be controlled by controlling the operating state of the second driving mechanism 33, thereby simplifying the operation of the user and increasing the intelligence degree of the air conditioning indoor unit 100.

Of course, the present application is not so limited; for example, the air conditioning indoor unit 100 may not be provided with the second driving mechanism 33, and in this case, the user may manually adjust the rotation angle of the air deflector 2 with respect to the driving arm 31.

In some embodiments of the present invention, as shown in fig. 23 to 25, a mounting cavity 31b is defined in the driving arm 31, the mounting cavity 31b is used for accommodating the second driving mechanism 33, and the driving shaft 3311 of the second driving mechanism 33 extends out of the mounting cavity 31b to connect with the connecting portion 20, so as to ensure that the second driving mechanism 33 can drive the air deflector 2 to rotate relative to the driving arm 31, and facilitate the installation and installation of the second driving mechanism 33, and the second driving mechanism 33 does not occupy too much space.

In some embodiments of the present invention, as shown in fig. 23 and 24, the second driving mechanism 33 includes a second motor 331, the second motor 331 has a connection line 3312, and an external power source, a control circuit board or the like may be electrically connected to the second motor 331 through the connection line 3312 to supply power to the second motor 331 or to control the operation of the second motor 331; a wiring groove 31c communicated with the installation cavity 31b is defined in the driving arm 31, the wiring groove 31c is used for arranging the connecting wires 3312 to realize the regular arrangement of the connecting wires 3312, and meanwhile, the wiring groove 31c can play a certain protection role on one end of the connecting wire 3312 connected with the second motor 331, so that the connecting wire 3312 is prevented from being easily damaged due to the fact that the connecting wire 3312 is excessively bent at the one end.

For example, as shown in fig. 23 and 24, the driving arm 31 may include an upper shell 311 and a lower shell 312, and the upper shell 311 and the lower shell 312 are buckled to define a mounting cavity 31b together, so as to facilitate mounting of the second driving mechanism 33; the wiring groove 31c may be formed on the upper case 311 and/or the lower case 312.

In some embodiments of the present invention, as shown in fig. 23, a portion of the connecting line 3312 extending out of the mounting cavity 31b has a spiral portion 3312a, and the spiral portion 3312a has a certain deformation capability and can deform in multiple directions of a three-dimensional space, so that the spiral portion 3312a can adapt to the movement of the driving arm 31 driving the second driving mechanism 33 relative to the housing 1, thereby preventing the connecting line 3312 from being excessively stretched during the movement of the second driving mechanism 33 relative to the housing 1 to cause the breakage of the connecting line 3312, and effectively solving the problems of routing and dragging of the connecting line 3312.

Alternatively, as shown in fig. 23, the wiring slot 31c extends through an end of the driving arm 31 away from the mounting cavity 31b, so as to ensure that the wiring slot 31c has a sufficient wiring length to effectively protect the connecting wire 3312.

Alternatively, the helical portion 3312a may extend along a two-dimensional helix, or a three-dimensional helix (such as a cylindrical helix, or a conical helix), or the like.

In some embodiments of the present invention, as shown in fig. 2 and 4, in the first position, the air deflector 2 closes the air outlet 10a, and the outer surface of the air deflector 2 is flush with the outer surface of the casing 1, so that the outer surface of the air deflector 2 and the outer surface of the casing 1 may be located on the same plane or the same curved surface, which is convenient for making a gap between the air deflector 2 and the air outlet 10a smaller when the air deflector 2 closes the air outlet 10a, thereby effectively reducing the overall size of the indoor air conditioner 100, reducing the overall thickness of the indoor air conditioner 100, and saving the occupied space of the indoor air conditioner 100.

In some embodiments, as shown in fig. 4 and 7, the two opposite side walls of the installation opening 10 are respectively formed with a sinking groove 10c, the sinking groove 10c may be formed by a corresponding side wall of the installation opening 10 being recessed toward a direction close to the central axis 1a of the casing 1, and in the first position, the air deflector 2 is fitted in the sinking groove 10c to close the air outlet 10a, so as to reduce a gap between the air deflector 2 and the air outlet 10a when the air deflector 2 closes the air outlet 10a, so as to facilitate making an outer surface of the air deflector 2 flush with the outer surface of the casing 1, and at the same time, reduce a distance between the air deflector 2 and the central axis 1a of the casing 1 when the air deflector 2 closes the air outlet 10a, which is beneficial to saving an occupied space when the air-conditioning indoor unit 100 is shut down; meanwhile, the sinking grooves 10c on the two opposite sides of the mounting opening 10 can limit the air deflector 2 to a certain extent, so that the air deflector 2 is prevented from rotating relative to the driving arm 31, and the air outlet 10a is stably closed by the air deflector 2. For example, in the example of fig. 4 and 7, the two sides (e.g., the left and right sides in fig. 7) of the width of the mounting opening 10 are respectively formed with the sunken grooves 10c, and when the air deflector 2 closes the air outlet 10a, the two sides of the width of the air deflector 2 are respectively fitted into the corresponding sunken grooves 10 c.

Further, the mounting opening 10 is formed as a square opening, the mounting opening 10a has four side walls, and a sinking groove 10c is formed on each side wall of the mounting opening 10a, so that the gap between the remaining air outlets 10a of the air deflector 2 when the air deflector 2 closes the air outlets 10a can be reduced.

In some embodiments of the present invention, as shown in fig. 15 and 16, the through opening 10b is further defined in the mounting opening 10, so that the outer contour of the through opening 10b does not exceed the outer contour of the mounting opening 10; the port 10b is provided at a distance from the outlet 10a, that is, the edge of the port 10b is provided at a distance from the edge of the outlet 10a, and obviously, the portion of the mounting port 10 excluding the outlet 10a may be formed as a "false air vent" which cannot realize the air outlet of the indoor unit 100, and the port 10b is formed on the portion corresponding to the "false air vent". Wherein, the one end of actuating arm 31 can stretch out opening 10b in order to link to each other with connecting portion 20 from casing 1, and then the setting of actuating arm 31 can not shelter from the air-out of air outlet 10a department, is favorable to guaranteeing that the air-out is smooth and easy.

For example, in the example of fig. 15, the mounting opening 10 is formed as a square opening and extends in the vertical direction, the length of the air outlet 10a is smaller than that of the mounting opening 10, so that "false air outlets" are respectively formed at the upper and lower ends of the mounting opening 10, so that through openings 10b are respectively disposed above and below the air outlet 10a, and each through opening 10b is correspondingly provided with a driving arm 31, so that the plurality of driving arms 31 drive the air deflector 2 to move, and the air deflector 2 is ensured to move stably.

In some embodiments, as shown in fig. 9 and 20, the connection portion 20 is formed on the inner side surface of the air deflector 2, so that when the air deflector 2 closes the air outlet 10a, a user cannot directly see the connection portion 20, and the hidden design of the connection portion 20 is facilitated in comparison with the case that the connection portion 20 is disposed at the end of the length of the air deflector 2; in the first position, the air deflector 2 closes the air outlet 10a, and the air deflector 2 blocks the through opening 10b, so that the user cannot directly see the through opening 10b, which is beneficial to improving the overall expressive force of the indoor unit 100 of the air conditioner.

In addition, because the connecting portion 20 is located inside the air deflector 2, the connecting portion 20 is convenient to be opposite to the through opening 10b, for example, the connecting portion 20 and the through opening 10b can be located at the same height position, which is beneficial to simplifying the structure of the driving arm 31 and reducing the cost, meanwhile, the air deflector 2 can also shield the driving arm 31 when the air outlet 10a is closed, and it is effectively ensured that the structures of the connecting portion 20, the through opening 10b, the driving arm 31, the second driving mechanism 32 and the like are not exposed when the air-conditioning indoor unit 100 is shut down, the appearance expression of the air-conditioning indoor unit 100 is improved, the connection appearance of the connecting portion 20 and the driving arm 31 is improved, and the movement adjustment of the whole air deflector 2 is convenient to realize. It will be appreciated that when the connecting portion 20 is pivotally connected to the driving arm 31, it is also possible to achieve a rotation of the air guiding plate 2 of approximately 360 ° relative to the driving arm 31, thereby ensuring the rotational flexibility of the air guiding plate 2.

In some embodiments, as shown in fig. 2, in a width direction (for example, a left-right direction in fig. 2) of the air deflector 2, a middle portion of an inner surface of the air deflector 2 protrudes toward a direction close to the central axis 1a of the casing 1, so that thicknesses of both sides of the width of the air deflector 2 are smaller than a thickness of the middle portion of the air deflector 2, which can reduce an obstruction effect on an air flow, better guide the air flow to a side portion of the air deflector 2, reduce an air flow loss, and improve a flow guiding effect of the air deflector 2.

Optionally, as shown in fig. 2, in the width direction of the air deflector 2, the middle of the outer surface of the air deflector 2 protrudes toward the direction away from the central axis 1a of the casing 1, so that the thicknesses of both sides of the width of the air deflector 2 are smaller than the thickness of the middle of the air deflector 2, which is convenient for matching the outer surface of the air deflector 2 with the surface of the casing 1, thereby improving the appearance performance of the indoor unit 100 of the air conditioner, and avoiding a large drop between the outer surface of the air deflector 2 and the surface of the casing 1 when the air deflector 2 closes the air outlet 10 a.

In some embodiments of the present invention, as shown in fig. 32 and 33, the air guiding plate 2 includes a plate body 21 and a reinforcing plate 22, an installation space 210 is defined in the plate body 21, the reinforcing plate 22 is disposed in the installation space 210, and the reinforcing plate 22 extends to two ends of the length of the air guiding plate 2 along the length direction of the air guiding plate 2, so that the reinforcing plate 22 can effectively improve the overall bending rigidity and the structural stability of the air guiding plate 2, and the length of the air guiding plate 2 has a wider setting range to better adapt to the actual differentiation requirement.

For example, in the example of fig. 32 and 33, the plate body 21 includes a first plate body 211 and a second plate body 212 that are connected in a snap-fit manner, the first plate body 211 and the second plate body 212 together define the installation space 210, and the reinforcing plate 22 may be provided on a wall surface of the first plate body 211 and/or the second plate body 212 corresponding to the installation space 210.

Alternatively, the reinforcing plate 22 may be a metal plate, but is not limited thereto. The cross section of the reinforcing plate 22 may be formed in a U shape, and the reinforcing plate 22 may be formed as a U-shaped reinforcing rib; of course, the cross section of the reinforcing plate 22 may also be formed in an i-shape or the like.

In some embodiments, as shown in fig. 32 and 33, the air guide plate 2 includes a plate body 21 and a heat insulating member 23, the plate body 21 defines an installation space 210, and the heat insulating member 23 is disposed in the installation space 210, so that the heat insulating member 23 can reduce the amount of heat transfer between a windward surface of the air guide plate 2 (i.e., an inner surface of the air guide plate 2) and a leeward surface of the air guide plate 2 (i.e., an outer surface of the air guide plate 2), thereby reducing a difference between the leeward surface of the air guide plate 2 and an ambient temperature and preventing the leeward surface of the air guide plate 2 from generating condensation.

For example, in the example of fig. 32 and 33, the air guide plate 2 includes a plate body 21, a reinforcing plate 22, and a heat insulating member 23, and both the reinforcing plate 22 and the heat insulating member 23 are provided in the installation space 210 of the plate body 21. The heat insulating member 23 may be filled in the installation space 210 except for the reinforcing plate 22, which is beneficial to improving the heat insulating effect of the heat insulating member 23.

The specific structure of the movable driving device 72 can be specifically set according to practical application, and it is only required to ensure that the movable driving device 72 can drive the switch door 71 to shield the air deflector 2 or avoid the air deflector 2.

In the example of fig. 1 and 3, there are two switching doors 71, when the air-conditioning indoor unit 100 is in the off state, the two switching doors 71 jointly block the air deflector 2, and the two switching doors 71 cooperate with the casing 1 to define the external appearance surface of the air-conditioning indoor unit 100, and when the air-conditioning indoor unit 100 is in the on state, one of the switching doors 71 moves towards one side of the width of the air outlet 10a, and the other switching door 71 moves towards the other side of the width of the air outlet 10a, so as to avoid the air deflector 2.
