[0058]

[0059] The realization, functional features and advantages of the object of the present invention will be further described in conjunction with the embodiments with reference to the accompanying drawings. Detailed implementation manners

[0060] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0061] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0062] In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0063] The present invention provides a driving mechanism and an air conditioner equipped with the driving mechanism. The air conditioner can be a split type or an integrated type. For a split air conditioner, it can be a wall-mounted air conditioner, a floor-standing air conditioner, a duct machine, a ceiling-mounted air conditioner, a ceiling cassette, etc. For an integrated air conditioner, it can be a window air conditioner, a portable air conditioner, etc.

[0064] Please refer to Figures 1 to 3 , taking the case of being installed in the indoor unit of a wall-mounted air conditioner as an example for the above driving mechanism. The indoor unit of the air conditioner includes a housing 10, and the housing 10 includes a front frame 10a and a panel 10b installed on the front frame 10a. An air outlet 101 is provided on the front frame 10a, and the air outlet 101 is usually located below the panel 10b. A driving mechanism is provided inside the panel 10b. The driving mechanism is connected to a wind blocking assembly 30, and the wind blocking assembly 30 is slidably installed on the driving mechanism in the up and down direction. Thus, the wind blocking assembly 30 has a first state of being received inside the housing 10b and a second state of blocking the front side of the indoor air outlet 101, thereby realizing the switching of the air outlet mode.

[0065] It should be noted that there are various forms of the wind blocking assembly 30. The wind blocking assembly 30 is a baffle, a micro-hole plate or a swirl module. The baffle is used to block the airflow from the air outlet 101 from blowing forward, the micro-hole plate is used to disperse the airflow and blow it out, and the swirl module is used to guide the airflow to blow out in a rotating manner. When the baffle blocks the front side of the air outlet 101, it can change the air outlet direction of the air outlet 101, so that the air outlet 101 blows air downward; when the micro-hole plate blocks the front side of the air outlet 101, the airflow can pass through the micro-holes, so that the airflow is dispersed, and both the wind speed and the air volume are reduced; for the swirl module, air passing holes 300 are provided thereon, and air blades 301 are provided in the air passing holes 300. The air blades 301 can be actively rotated or passively rotated. When the airflow blows out from the air outlet 101 and passes through the air passing holes 300, whether the air blades 301 are actively rotated or passively rotated, the airflow can be sent out in a rotating manner. After the rotating airflow blows out, it mixes with the surrounding air, so that the blown airflow is softer.

[0066] The structure of the driving mechanism will be elaborated in detail in the following content.

[0067] Please refer to Figure 4 、 Figure 5 and Figure 6, the driving mechanism includes a base 20 and a movable plate 20d, and the movable plate 20d is slidably mounted on the base 20 in the vertical direction. There can be one or two movable plates 20d. The base 20 can be an integral unit (the base 20 can extend in the length direction of the panel 10b or have a size substantially the same as that of the movable plate 20d), or the base 20 can include two separate parts. Thus, the installation relationship between the movable plate 20d and the base 20 can be that one movable plate 20d is installed on an integral base 20 (in the case where the base 20 extends in the length direction of the panel 10b, the movable plate 20d can be installed at the middle position of the base 20; in the case where the size of the base 20 is substantially the same as that of the movable plate 20d, the base 20 can be installed at the middle position of the panel 10b or the face frame 10a); or two movable plates 20d can be respectively installed at both ends in the length direction of an integral base 20, and the two movable plates 20d are arranged at intervals in the length direction of the panel 10b.

[0068] In the following content, mainly taking the case where two movable plates 20d are installed at both ends in the length direction of the base 20 as an example for introduction.

[0069] Please refer to Figure 7 、 Figure 8 、 Figure 9 and Figure 10 , a guide rail 20f is provided on the movable plate 20d. The guide rail 20f is detachably fixed on the movable plate 20d. One end of the guide rail 20f is inserted or snapped into the movable plate 20d, and the other end is fixed to the movable plate 20d by screws (so as to facilitate the installation and disassembly of the guide rail 20f). A guide chute 224 ( Figure 9 and Figure 10 ) is provided on the base 20. The guide rail 20f is adapted to the guide chute 224, so that the movable plate 20d can slide up and down relative to the base 20 through the cooperation of the guide rail 20f and the guide chute 224. It should be noted that in the air conditioner indoor unit, a drive source may not be provided in the driving mechanism, that is, the user can manually operate the wind deflector assembly 30 to move up and down. A drive source can also be provided in the driving mechanism, and by controlling the drive source, the automatic lifting of the wind deflector assembly 30 can be realized.

[0070] Please continue to refer to Figure 6 and Figure 7 , the basic structure of the base 20 is as follows: it includes a base 20a and two side wings 20b. The two side wings 20b are respectively arranged at both ends of the base 20a. The base 20a has a first side 201 extending from one end to the other end, and the two side wings 20b protrude from the first side 201 (the base 20a and the side wings 20b can be integrally formed or connected by a connecting member). Thus, in the air conditioner indoor unit, the entire base 20 can be generally in an inverted U-shaped structure.

[0071] Due to the limited space between the front panel 10b and the front frame 10a in the air conditioner indoor unit, both the wind deflector assembly 30 and the base 20a have a certain thickness. If the base 20a and the wind deflector assembly 30 are installed between the front panel 10b and the front frame 10a in a stacked manner, then at the beginning of the design, a relatively large gap needs to be reserved between the front panel 10b and the front frame 10a, which will affect the overall shape of the air conditioner indoor unit (the air conditioner indoor unit appears thicker). In addition, the width of the air outlet 101 is generally about 15 cm, so the width of the wind deflector assembly 30 is generally designed according to the width of the air outlet 101, and its width is not much different from that of the air outlet 101. Since the width of the entire front panel 10b is relatively large, even if the wind deflector assembly 30 and the base 20 are stacked, when the wind deflector assembly 30 is stored inside the front panel 10b, there is still a large amount of space remaining between the front panel 10b and the front frame 10a that is not utilized, resulting in space waste.

[0072] Therefore, after the base 20 is set to an inverted U-shaped structure, the wind deflector assembly 30 can be arranged at the middle notch of the inverted U-shaped structure, thereby greatly improving the space utilization rate between the front panel 10b and the front frame 10a.

[0073] Please continue to refer to Figure 11 and Figure 12 , the base 20 further includes a motor box 20c installed on the side wing 20b. The motor box 20c is detachably fixed to the side wing 20b, so the installation and disassembly of the motor box 20c are relatively convenient. The motor box 20c itself forms a recess 222 for accommodating the stepper motor 220a. A groove 211 for accommodating the recess 222 is formed on the side wing 20b. A plug hole 214 is provided on the side wing 20b. One end of the motor box 20c is provided with a lug 225a, and the other end of the motor box 20c is fixed to the side wing 20b through a connecting member. As shown in Figure 11 and Figure 12 , the other end of the motor box 20c is provided with a screw hole 225b and a positioning hole 225c. The side wing 20b is provided with a screw post 215 corresponding to the position of the fixing hole 212a and a positioning post 216 beside the screw post 215. When installing the motor box 20c on the side wing 20b, first insert the lug 225a into the plug hole 214, then gradually place the recess 222 into the groove 211, then fit and insert the positioning hole 225c and the positioning post 216, and finally insert the screw into the screw hole 225b and screw it into the screw post 215 to complete the installation of the motor box 20c. After the motor box 20c is installed on the side wing 20b, on the one hand, both ends of the motor box 20c are fixed, and on the other hand, due to the adaptation of the groove 211 and the recess 222, the installation of the motor box 20c on the side wing 20b is more stable.

[0074] Please refer to Figure 7 , Figure 11and Figure 12 Inside the motor box 20c, a stepper motor 220a and a first gear 221a are installed. The stepper motor 220a is fixed in the recessed portion 222 of the motor box 20c by screws, and the first gear 221a is installed on the motor shaft of the stepper motor 220a. A first wire groove 223 is provided on the motor box 20c. The lug 225a and the insertion hole 214 of the motor box 20c are located in the extending direction of the first wire groove 223. A first wire clip 226 is provided at the notch of the first wire groove 223. The wire 20g connecting the stepper motor 220a penetrates into the first wire groove 223, and under the limiting action of the first wire clip 226, the wire 20g is not easily disengaged from the first wire groove 223.

[0075] Under normal circumstances, a display module is to be set on the panel 10b, such as displaying parameters like the target temperature, the air conditioner operation mode, the humidity, etc.; and the positions of the display module and the driving mechanism are both inside the panel 10b. Please refer to Figure 13 To improve the assembly efficiency of the air conditioner indoor unit, the display module (the display module is not installed in the figure) can be integrated onto the base 20. The wire 20g connecting the stepper motor 220a can be connected to the display module and then connected to the electric control box through the display module. The side wing 20b is at a certain distance from the display module. Please continue to refer to Figure 11 and Figure 12, to prevent the wire 20g connecting the stepper motor 220a from being exposed after being led out of the first wire groove 223, in one embodiment, a second wire groove 202 is provided on the base 20a. The second wire groove 202 extends from the side wing 20b towards the display box. The wire 20g enters the second wire groove 202 after passing through the first wire groove 223 and then penetrates into the display box. Since the first wire groove 223 extends in the up and down direction and the second wire groove 202 extends in the left and right direction, if the wire 20g directly enters the second wire groove 202 after being led out of the first wire groove 223, then affected by the second wire groove 202, the wire 20g will deflect towards the direction of the second wire groove 202 in the first wire groove 223. Over time, the wire 20g may come out of the first wire groove 223, and further may also cause the wire 20g to come out of the second wire groove 202. In view of this, in one embodiment, a wire passing hole 203 is provided on the base 20a. The wire passing hole 203 is located between the first wire groove 223 and the second wire groove 202. In this way, the wire passing hole 203 is relatively close to the first wire groove 223, which can slow down the deflection force of the wire 20g from coming out of the first wire groove 223. Further, since there is also a certain distance between the wire passing hole 203 and the first wire groove 223, if this distance is too long, the wire 20g will appear lengthy here. The lengthy wire 20g will fall downward between the wire passing hole 203 and the second wire groove 202, and may finally fall to the notch of the inverted U-shaped base 20, thus interfering with the up and down sliding of the windshield assembly 30 and even causing a safety accident; on the other hand, the wire 20g may also fall from below the panel 10b to the air outlet 101, thus seriously affecting the user experience. To avoid this situation, in another embodiment, a wire pressing plate 204 is further provided on the base 20a. The wire pressing plate 204 is located between the wire passing hole 203 and the second wire groove 202. The lower end of the wire pressing plate 204 is connected to the base 20a and extends upward. The setting of the wire pressing plate 204 can, on the one hand, press the wire 20g on the base 20a, and on the other hand, can also play a role in carrying the wire 20g. Even if the wire 20g is slightly lengthy, it will not fall to the notch of the base 20.

[0076] For the second wire groove 202, its main function is to accommodate and hide the wire 20g. In one embodiment, to facilitate the installation of the wire 20g in the second wire groove 202, the notch of the second wire groove 202 faces the panel 10b, and a second wire clip 205 is provided at the notch of the second wire groove 202. The second wire groove 202 has two side walls extending in the left and right direction. The second wire clip 205 is connected to one of the side walls, and an avoidance notch 206 is provided on the other side wall corresponding to the second wire clip 205. When wiring, bypass the second wire clip 205 through the avoidance notch 206, so that it is more convenient for both wiring and removing the wire 20g from the second wire groove 202.

[0077] Among the two side wings 20b of the base 20, the notch of the first wire groove 223 on one of the side wings 20b faces the other side wing 20b. In this way, it is convenient to hide the wire 20g, and the user cannot see the wire 20g whether observing the base 20 from the front side or the rear side.

[0078] In addition, the motor box 20c is in sliding fit with the guiding slide rail 20f. The above-mentioned guiding chute 224 is provided on the motor box 20c, and the opening direction of the guiding chute 224 is opposite to the opening direction of the first wire groove 223. Because the guiding chute 224 is laterally opened (in the air-conditioning indoor unit, the opening of the guiding chute 224 is to the left or right), the guiding chute 224 has a limiting effect on the guiding slide rail 20f, and can limit the forward or backward displacement of the guiding slide rail 20f. Since both the guiding slide rail 20f and the guiding chute 224 extend in the up and down directions, after the guiding slide rail 20f and the guiding chute 224 are matched, the guiding slide rail 20f can only slide in the up and down directions in the guiding chute 224.

[0079] Please continue to refer to Figures 7 to 10 , a rack is provided on the guiding slide rail 20f, and the rack meshes with the first gear 221a. When the stepping motor 220a works, the guiding slide rail 20f can be driven to move up and down through the first gear 221a. Please refer to Figure 18 , the guiding slide rail 20f includes a rack plate 241 and a track plate 242. A gap is formed between the rack plate 241 and the track plate 242. A rack meshing with the first gear 221a is provided on the rack plate 241, and the track plate 242 is inserted into the guiding chute 224. In order to make the sliding fit resistance between the guiding slide rail 20f and the guiding chute 224 smaller, a plurality of first columnar bodies 243 are provided on the track plate 242. One side wall of the first columnar body 243 protrudes from one side surface of the track plate 242, and the other side wall protrudes from the other side surface of the track plate 242. In this way, when the track plate 242 is inserted into the guiding chute 224, the side wall of the first columnar body 243 abuts against the inner wall of the guiding chute 224, so that the friction is smaller and the sliding of the guiding slide rail 20f and the guiding chute 224 is smoother.

[0080] The above-mentioned realization method of the up and down movement of the movable plate 20d can be that one guiding slide rail 20f is matched with one guiding chute 224, or two guiding slide rails 20f are matched with two guiding chutes 224. Considering that the panel 10b of the wall-mounted air-conditioning indoor unit extends in the left and right directions, in order to make the windshield assembly 30 slide more smoothly, it is a preferred embodiment to provide guiding slide rails 20f on both movable plates 20d and guiding chutes 224 on both side wings 20b. In addition, sliding driving components are also provided on both side wings 20b.

[0081] Please refer toFigure 6 , Figure 14 and Figure 15 , in order to make the windshield assembly 30 slide more smoothly, in a preferred embodiment, a deviation correction guide rail 20e is provided on the base 20, and a guide groove 251a slidably adapted to the deviation correction guide rail 20e is provided on the movable plate 20d. The deviation correction guide rail 20e can be one or two. The main function of the deviation correction guide rail 20e is to improve the sliding stability of a single movable plate 20d. The deviation correction guide rail 20e extends in the up and down direction, and the deviation correction guide rail 20e and the guiding slide rail 20f are spaced apart. For the embodiment in which only one deviation correction guide rail 20e is installed on the base 20, the installation position of the deviation correction guide rail 20e can be various. For example, one of the guiding slide rails 20f is located between the deviation correction guide rail 20e and the other guiding slide rail 20f, or the deviation correction guide rail 20e is located between the two guiding slide rails 20f. For the embodiment in which two deviation correction guide rails 20e are installed on the base 20, there are also various installation methods for the deviation correction guide rails 20e. For example, both deviation correction guide rails 20e are located between the two guiding slide rails 20f, or the deviation correction guide rails 20e and the guiding slide rails 20f are alternately arranged, or the two guiding slide rails 20f are located between the two deviation correction guide rails 20e.

[0082] The following mainly elaborates on the installation of the deviation correction guide rail 20e.

[0083] Considering that when the windshield assembly is connected to the movable plate 20d, it is mainly connected to the inner side of the movable plate 20d (near the notch position in the middle of the inverted U-shaped base 20), so the inner side of the movable plate 20d needs to bear the gravity of the windshield assembly 30, and the outer side of the movable plate 20d tends to tilt inward.

[0084] The windshield assembly 30 itself extends along the length direction of the panel 10b (the windshield assembly 30 is used to block the air outlet 101, and the air outlet 101 extends in the left and right directions), and the windshield assembly 30 is relatively long (about 0.6 m to 1 m). The installation of such a long windshield assembly 30 on the movable plate 20d has a certain tolerance. In addition, the base 20 and the movable plate 20d are plastic parts. Therefore, when the movable plate 20d moves in the up and down direction, once the strokes at both ends of the windshield assembly 30 are inconsistent (one end is high and the other end is low), the movable plate 20d will be stuck, and the windshield assembly 30 cannot move up and down.

[0085] The setting of the deviation correction guide rail 20e on the one hand provides more tracks for the movement of the windshield assembly 30, making the movement of the windshield assembly 30 smoother. On the other hand, after the guiding slide rail 20f and the deviation correction guide rail 20e are combined, when the movable plate 20d slides up and down, the guiding slide rail 20f and the deviation correction guide rail 20e restrict each other, so that the left and right swing amplitude during the movement of the movable plate 20d can be reduced, and further the problem of inconsistent strokes at both ends caused by the up and down movement of the windshield assembly 30 can be reduced.

[0086] Since the connection between the windshield assembly 30 and the movable plate 20d is biased towards the inner side of the movable plate 20d, in one embodiment, please refer to Figure 6 , Figure 14 , Figure 16 and Figure 17 , in order to make the rectifying effect of the rectifying guide rail 20e better, the rectifying guide rail 20e is installed on the inner side edge of the flank 20b ( Figure 14 and Figure 16 ). It should be noted that the flank 20b has an outer side edge facing away from the base 20a and an inner side edge opposite to the outer side edge. In the figure, the flank 20b is integrally formed with the base 20a, and a part of the inner side edge of the flank 20b overlaps with the base 20a. At the junction of the flank 20b and the base (for the convenience of description, this inner side edge is defined as X1), another part of the inner side edge of the flank 20b protrudes from the first side edge 201 (defined as X2). The rectifying guide rail 20e can be installed at any position on the inner side edge of the flank 20b as long as it can cooperate with the sliding of the movable plate 20d. For the embodiment in which the rectifying guide rails 20e are installed on both flanks 20b, one rectifying guide rail 20e can be installed at X1 or X2. Of course, both rectifying guide rails 20e can be installed at X1 or both can be installed at X2. In order to make the overall operation of the movable plate 20d smoother, the two rectifying guide rails 20e are staggered in the direction perpendicular to the sliding of the movable plate 20d (that is, one rectifying guide rail 20e is installed at X1 and the other rectifying guide rail 20e is installed at X2). With such an arrangement, the two rectifying guide rails 20e give each other an oblique supporting force through the windshield assembly 30. In addition, with the guiding function of the two guiding slide rails 20f, the two movable plates 20d slide more smoothly. This arrangement of the two rectifying guide rails 20e makes the line connecting the midpoints of the two rectifying guide rails 20e, the extending direction of the rectifying guide rail 20e, and the two movable plates 20d always form a triangle, thus making the stability better.

[0087] In order to facilitate the assembly and fixation of the rectifying guide rail 20e, in one embodiment, side plates 212, 212' are formed on the inner side edge of the flank 20b ( Figure 7 , Figure 12 and Figure 14), the deviation-correcting guide rail 20e is snap-connected to the side plate 212. Specifically, the deviation-correcting guide rail 20e includes a deviation-correcting chute 231a and a deviation-correcting rib 232a provided in the deviation-correcting chute 231a. The deviation-correcting chute 231a is sleeved on the side plate 212 (before being fixed to the side wing 20b, the deviation-correcting chute 231a can slide up and down along the side plate 212). A guide groove 251a is provided on the movable plate 20d, and the guide groove 251a is in sliding fit with the deviation-correcting rib 232a. On the same side wing 20b, the notch of the deviation-correcting chute 231a faces the guiding slide rail 20f on the side wing 20b, and the deviation-correcting rib 232a is located on the side of the deviation-correcting chute 231a facing away from the guiding slide rail 20f on the side wing 20b. In this way, in the front-rear direction, the guide groove 251a can hold and limit the deviation-correcting rib 232a.

[0088] In addition, in order to facilitate the disassembly and assembly of the deviation-correcting chute 231a, the deviation-correcting chute 231a can be fixed to the side wing 20b in a detachable manner. In one embodiment, fixing holes 212a are provided on the side plate 212, and clamping platforms 236 corresponding to the positions of the fixing holes 212a are provided on the inner groove wall of the deviation-correcting chute 231a. In this way, when installing the deviation-correcting guide rail 20e, after the clamping platforms 236 are snapped into the fixing holes 212a, the deviation-correcting chute 231a can be firmly fixed to the side plate 212 (in the up-down direction, the deviation-correcting chute 231a and the side plate 212 can remain relatively fixed). To make the installation of the deviation-correcting guide rail 20e more stable, a first fixing groove 212b (located at the lower end of the side wing 20b and in the shape of a notch) is provided on the side wing 20b inside the side plate 212. The deviation-correcting chute 231a has two side edges extending along the sliding direction of the side plate 212. A first clamping platform 234 for clamping the side plate 212 is provided on one side edge, and a second clamping platform 235 for cooperating with the first fixing groove 212b is provided on the other side edge. In this way, the first clamping platform 234 can clamp one side of the side plate 212, so as to keep one side wall of the deviation-correcting chute 231a relatively fixed to the side plate 212, and the second clamping platform 235 can fix the other side wall of the deviation-correcting chute 231a to the side plate 212. Further, please continue to refer to Figure 14 , a stop portion 213 is provided on the first side edge 201 of the base 20a, a second fixing groove 213a is formed between the stop portion 213 and the side plate 212, and the deviation-correcting chute 231a is inserted into the second fixing groove 213a. To facilitate the assembly of the deviation-correcting guide rail 20e, the clamping platforms 236 and the second clamping platforms 235 are provided at the end of the deviation-correcting chute 231a away from the base 20a.

[0089] Furthermore, please refer to Figure 15, To facilitate the installation and disassembly of the deviation correction chute 231a, the above-mentioned clamping platform 236 is triangularly arranged. That is, when the upper port of the deviation correction chute 231a is aligned with the lower end of the side plate 212, the deviation correction chute 231a is pushed upward. The first clamping platform 234 is clamped with one side of the side plate 212. When the clamping platform 236 abuts against the lower end of the side plate 212, continue to push the deviation correction chute 231a upward with force. At this time, because the clamping platform 236 is triangularly arranged, one side of the clamping platform 236 is an inclined surface. Under the guiding action of this inclined surface, the clamping platform 236 gradually crosses the lower end of the side plate 212. And under the abutting action of the clamping platform 236 and the side plate 212, the side plate 212 and / or the deviation correction guide rail 20e deforms. Until the clamping platform 236 is clamped into the fixing hole 212a, the side plate 212 and / or the deviation correction guide rail 20e returns to its original shape, so that the bottom of the deviation correction chute 231a can be firmly attached to the side plate 212. In summary, the deviation correction chute 231a firmly fixes the deviation correction guide rail 20e on the side plate 212 through four fixing methods (the upper end of the deviation correction chute 231a is inserted into the second fixing groove 213a, the first clamping platform 234 is clamped with the side plate 212, the second clamping platform 235 is clamped with the first fixing groove 212b, and the clamping platform 236 is clamped into the fixing hole 212a).

[0090] Please continue to refer to Figure 14 and Figure 15 , the deviation correction rib 232a is generally flush with one side of the deviation correction chute 231a. The deviation correction rib 232a is clamped into the guide groove 251a. To reduce the friction between the deviation correction rib 232a and the inner wall of the guide groove 251a, a plurality of second columnar bodies 233 are provided on the deviation correction rib 232a. That is, the guide groove 251a has two opposite side walls. At least two arc-shaped protrusions 233a (the arc-shaped protrusions 233a are the side walls of the second columnar body 233) are respectively provided on both sides of the deviation correction rib 232a. The arc-shaped protrusions 233a located on both sides of the deviation correction guide rail 20e respectively abut against the two side walls of the guide groove 251a.

[0091] For the two deviation correction guide rails 20e, their structures can be the same or different. In another embodiment, please refer to Figure 16 and Figure 17 , the deviation correction guide rail 20e includes a deviation correction chute 231b. A guiding portion 251b is provided on the movable plate 20d. The guiding portion is provided inside the wing 20b (generally located at the junction with the base 20a. The base 20a and the wing 20b may not have an obvious junction line, and the two may be integrally formed, or of course, they may be assembled). The guiding portion 251b is slidably arranged in the deviation correction chute 231b.

[0092] Please refer to Figure 17, in order to further reduce the frictional resistance between the deviation-correcting chute 231b and the guiding portion 251b, the deviation-correcting guide rail 20e further includes a deviation-correcting rib 232b provided on the inner wall of the deviation-correcting chute 231b. The deviation-correcting rib 232b abuts against the guiding portion 251b. The deviation-correcting rib 231b extends in the up-down direction, and the contact area between it and the guiding portion 251b is small, so the sliding is smoother.

[0093] Since the deviation-correcting guide rail 20e needs to ensure the sliding track of the movable plate 20d, the material of the deviation-correcting guide rail 20e can be set as a rigid material, such as stainless steel, aluminum alloy, etc.; in addition, since the deviation-correcting guide rail 20e slides in the guide groove 251a for a long time, in order to make the deviation-correcting guide rail 20e slide more smoothly, the material of the deviation-correcting guide rail 20e can use a self-lubricating wear-resistant material.

[0094] When the wind shield assembly 30 is a swirl module, the wind blades 301 provided in the wind shield assembly 30 can be rotated by an active driving method. In one embodiment, a wind blade 301 driving component is further provided on one of the movable plates 20d. The wind blade 301 driving component is connected to the wind blade 301 and is used to drive the wind blade 301 to rotate. The wind blade 301 driving component includes a driving motor 220b and a second gear 221b, and the second gear 221b is in transmission connection with the wind blade 301.

[0095] Please refer to Figure 11 、 Figure 12 and Figure 18 , the movable plate 20d moves up and down, the wind blade 301 driving component moves together with the movable plate 20d, and the motor wire 20g connecting the driving motor 220b also needs to move together. Therefore, the motor wire 20g needs to have a certain redundant length. A wire groove 227 for routing the motor wire 20g is provided on the base 20. The motor wire 20g passes through the inlet 228 of the wire groove 227 and enters the wire groove 227, and then is connected to the display box. Since the opening direction of the inlet 228 is approximately at a 90° angle to the up-down direction, after the redundant motor wire 20g is led out from the inlet 228, it is easy to have a large-angle bend during the movement. If this continues for a long time, the motor wire 20g is prone to fatigue and thus breakage. On the one hand, it affects the operation of the wind shield assembly 30, on the other hand, it reduces the service life of the air conditioner indoor unit, and furthermore, it is easy to cause safety accidents.

[0096] In addition, the closer the wire groove 227 is to the driving motor 220b, the more likely the motor wire 20g located between the two is to have a large-angle bend. Therefore, the wire groove 227 and the driving motor 220b should be spaced apart in the length direction of the panel 10b. The longer the spacing, the less likely the motor wire 20g is to have a large-angle bend.

[0097] In one embodiment, please refer to Figures 19 to 21, in order to avoid large-angle bending of the long motor wire 20g, a first guiding portion 229 is provided at the wire inlet 228 of the wire passing groove 227. The first guiding portion 229 can extend obliquely upward from the wire inlet 228 or extend obliquely downward from the wire inlet 228. The above-mentioned oblique extension can be along a straight line or along an arc. If the first guiding portion 229 extends obliquely downward from the wire inlet 228, then when the movable plate 20d moves downward, the first guiding portion 229 will have a certain bearing capacity for the motor wire 20g and can also reduce the bending angle of the motor wire 20g at the end of the first guiding portion 229. If the first guiding portion 229 extends obliquely upward from the wire inlet 228, then when the movable plate 20d moves upward, under the action of the first guiding portion 229, after the motor wire 20g is led out from the wire inlet 228, under the guidance of the first guiding portion 229 and the action of the self-gravity of the motor wire 20g, the motor wire 20g will not be bent too much.

[0098] If the number of the first guiding portions 229 is only one, the preferred setting method is to extend the first guiding portion 229 obliquely downward from the wire inlet 228.

[0099] Considering that the guiding effect of a single first guiding portion 229 is not as good as that of two first guiding portions 229, in an embodiment, two first guiding portions 229 are provided at the wire inlet 228. One first guiding portion 229 bends obliquely downward from the wire inlet 228, and the other first guiding portion 229 bends obliquely upward from the wire inlet 228. In this way, whether the movable plate 20d moves upward or downward, the first guiding portion 229 can guide the long motor, thereby avoiding too large a bending angle of the motor wire 20g.

[0100] In addition, define the length s1 of the first guiding portion 229 extending downward from the wire inlet 228, and define the length of the first guiding portion 229 extending upward from the wire inlet 228 as s2. It is better that s1 is greater than s2. This is because when the motor wire 20g moves, it will be affected by its own action. When the motor wire 20g contacts the end of the first guiding portion 229 extending downward, it is more likely to bend at a large angle. Therefore, if the length of the first guiding portion 229 itself is increased, the tangent line at the end of the first guiding portion 229 may coincide (or basically coincide) with the extending direction of the motor wire 20g. In this way, after the wire 20g passes through the first guiding portion 229, the extension is smoother.

[0101] In another preferred embodiment, in order to make the guiding effect of the two first guiding portions 229 better, a gap is formed between the two first guiding portions 229, and the gap is flared in the direction away from the wire inlet 228. On the one hand, the two first guiding portions 229 are arc-shaped, and the gap between them is flared. Thus, the tangential angle between the two first guiding portions 229 will also become larger as the distance from the wire inlet 228 increases, thereby reducing the large-angle bending of the motor wire 20g.

[0102] The large-angle bending of the motor wire 20g depends not only on the position of the wire inlet 228 but also on the wire outlet angle of the driving motor 220b itself. In one embodiment, a second guiding portion 261 is provided on the movable plate 20d. The second guiding portion 261 is located around the driving motor 220b. The second guiding portion 261 extends downward or upward obliquely toward the side where the wire passing groove 227 is located.

[0103] Of course, similar to the case of the first guiding portion 229, it is preferable to provide two second guiding portions 261. That is, two second guiding portions 261 are provided on the movable plate 20d, and the two second guiding portions 261 are spaced apart. One of the second guiding portions 261 is bent downward, and the other second guiding portion 261 is bent upward. The bending effect of the second guiding portion 261 can refer to that of the first guiding portion 229.

[0104] In addition, since the motor wire 20g is usually welded to the interface of the motor, if the interface where the motor wire 20g is connected to the motor is subjected to a pulling force, it is easy to cause the solder joint at the interface to become loose, resulting in poor contact of the driving motor 220b. Seriously, it will directly cause the motor wire 20g to separate from the motor. In view of this, in one embodiment, a wire winding portion 262 is provided between the two second guiding portions 261, and the wire winding portion 262 is spaced apart from the two second guiding portions 261. After the wire winding portion 262 is provided, the motor wire 20g can be wound around the wire winding portion 262. Even if it is subjected to a pulling force, the motor wire 20g can disperse most of the pulling force to the wire winding portion 262, thereby avoiding the loosening of the solder joint between the motor wire 20g and the motor interface.

[0105] There are various ways for the motor wire 20g to run between the two second guiding parts 261. For example, the gap between the winding part 262 and one of the second guiding parts 261 close to the driving motor 220b is defined as gap one, and the gap between the winding part 262 and the other second guiding part 261 is defined as gap two. After the motor wire 20g is led out from the driving motor 220b, it first passes through gap one, then through gap two, and then enters the wire inlet 228 through the gap between the two first guiding parts 229. It can also be that after the motor wire 20g is led out from the motor, it first passes through gap two, then through gap one, and then enters the wire inlet 228 through the gap between the two first guiding parts 229. That is, the motor wire 20g connecting the driving motor 220b winds around the outer periphery of the winding part 262 and enters the wire passing groove 227 through the gap between the two first guiding parts 229. For this way of winding once, if the motor wire 20g suddenly receives a large pulling force when the movable plate 20d moves up and down, almost all of this pulling force can be transferred to the winding part 262 in an instant. Therefore, the setting of the winding part 262 provides excellent protection for the connection of the motor wire 20g.

[0106] For the embodiment without the winding part 262, the winding method can also be that after the motor wire 20g is led out from the motor, it winds around the outer periphery of the driving motor 220b, passes through the gap between the two second guiding parts 261, and enters the wire passing groove 227 through the gap between the two first guiding parts 229. That is, the outer wall of the driving motor 220b replaces the function of the above-mentioned winding part 262. When the motor wire 20g receives a sudden pulling force, this pulling force can be instantaneously offset by the frictional force generated between the driving motor 220b and the motor wire 20g, thereby playing a protective role in the connection of the motor wire 20g.

[0107] The movable plate 20d has two extreme positions of moving to the uppermost and lowermost positions, and the stroke between the two extreme positions is the maximum stroke of the movable plate 20d. The length of the redundant motor wire 20g between the wire inlet 228 and the winding part 262 must always be greater than the straight-line distance between the wire inlet 228 and the winding part 262. Otherwise, during the up and down movement of the movable plate 20d, the motor wire 20g will be subjected to a severe pulling force. In addition, the redundant motor wire 20g between the wire inlet 228 and the winding part 262 should not be too long, because the too long motor wire 20g will get entangled and knotted between the wire inlet 228 and the winding part 262, thus easily causing the motor wire 20g to be prematurely fatigued and damaged. Therefore, the best way is that the length of the motor wire 20g between the wire inlet 228 and the winding part 262 is slightly greater than the straight-line distance between the wire inlet 228 and the winding part 262. For example, if the straight-line distance between the wire inlet 228 and the winding part 262 is L1, and the length of the motor wire 20g between the wire inlet 228 and the winding part 262 is L2, then 1.1×L1 ≤ L2 ≤ 1.3×L2. Of course, since there are two extreme positions, upper and lower, of the movable plate 20d, in order to simultaneously satisfy that when the movable plate 20d is at the upper and lower extreme positions, the length of the motor wire 20g between the wire inlet 228 and the winding part 262 is just slightly greater than the straight-line distance between the wire inlet 228 and the winding part 262, in this embodiment, the wire inlet 228 can be set in the middle of the maximum stroke of the movable plate 20d, that is, the wire inlet 228 is roughly centered on the maximum stroke of the movable plate 20d.

[0108] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
