Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a drive mechanism and an air conditioner. Background Technology

[0002] Current windless air conditioner products typically use a diffuser panel to disperse airflow to achieve a windless effect. The current solution involves switching between normal air supply mode and windless air supply mode by moving the wind deflector component up and down.

[0003] However, when the wind deflector assembly moves up and down, some of the wires also move up and down together. During this process, these motor wires are prone to large-angle bends or tangling. Under such conditions for a long time, the motor wires are prone to fatigue and damage, which affects the service life of the air conditioner. Summary of the Invention

[0014] In one embodiment, the movable plate is provided with two second guide portions, which are spaced apart, one of which bends downward and the other bends upward.

[0015] In one embodiment, a winding portion is provided between the two second guide portions, and the winding portion is spaced apart from the two second guide portions.

[0016] In one embodiment, the motor wire connected to the drive motor is wound around the outer periphery of the winding portion and passes through the gap between the two first guide portions into the wire guide groove.

[0017] In one embodiment, the motor wires of the drive motor are wrapped around the outer periphery of the drive motor and pass through the gap between the two second guides and the gap between the two first guides into the wire guide groove.

[0018] In one embodiment, the inlet is located at the middle of the maximum travel of the movable plate.

[0019] In one embodiment, the base includes a base and two side wings, the side wings being disposed at both ends of the base and protruding from the lower side of the base, and the two movable plates being respectively slidably mounted on the two side wings.

[0020] In one embodiment, the drive mechanism further includes a motor housing detachably mounted to the side wing.

[0021] In one embodiment, the drive mechanism further includes a guide rail fixed to the movable plate, and a guide groove is provided on one side of the motor box, the guide groove being adapted to the guide rail.

[0023] In one embodiment, a recess is formed on the motor housing to accommodate the drive motor, and a groove is formed on the side wing to accommodate the recess.

[0024] To achieve the above objectives, the present invention also provides an air conditioner, including a drive mechanism and a wind deflector assembly; the drive mechanism includes:

[0025] A base, wherein a wire passage groove is provided on the base and the wire passage groove has a wire inlet;

[0026] A movable plate, which is slidably mounted on the base;

[0027] A drive motor is mounted on the movable plate. The drive motor is connected to a motor wire. The motor wire passes through the wire inlet and enters the wire guide groove. The wire inlet of the wire guide groove is provided with a first guide part for guiding the motor wire.

[0055]

[0056] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0058] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0059] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0060] This invention proposes a drive mechanism and an air conditioner equipped with the drive mechanism. The air conditioner can be either a split-type or an integrated type. For split-type air conditioners, it can be a wall-mounted unit, a floor-standing unit, a ducted unit, a ceiling-mounted unit, or a ceiling-mounted unit, etc. For integrated air conditioners, it can be a window unit, a portable unit, etc.

[0061] Please see Figures 1 to 3 The driving mechanism described above will be illustrated using an example of a wall-mounted air conditioner indoor unit. The indoor unit includes a housing 10, which includes a frame 10a and a panel 10b mounted on the frame 10a. An air outlet 101 is provided on the frame 10a, typically located below the panel 10b. A driving mechanism is located inside the panel 10b, connected to a wind deflector 30. The wind deflector 30 is slidably mounted on the driving mechanism in the vertical direction, allowing it to have a first state where it is retracted inside the housing 10b, and a second state where it blocks the air outlet 101. This achieves the switching of the airflow mode.

[0062] It should be noted that the wind deflector assembly 30 can take many forms, such as a baffle, a micro-perforated plate, or a vortex module. The baffle is used to block the airflow from the air outlet 101 from blowing forward, the micro-perforated plate is used to disperse the airflow, and the vortex module is used to guide the airflow to rotate and blow it out. A baffle is placed in front of the air outlet 101 to change the air outlet direction, causing the air outlet 101 to blow air downwards. A micro-perforated plate is placed in front of the air outlet 101 to allow the airflow to pass through the micro-perforations, thereby dispersing the airflow and reducing the wind speed and volume. For the vortex module, there is an air passage 300, and a fan blade 301 is installed inside the air passage 300. The fan blade 301 can rotate actively or passively. When the airflow blows out of the air outlet 101 and passes through the air passage 300, whether the fan blade 301 rotates actively or passively, it can send the airflow out in a rotating manner. The rotating airflow mixes with the surrounding air after being blown out, thus making the blown airflow softer.

[0063] The structure of the drive mechanism will be described in detail below.

[0064] Please see Figure 4 , Figure 5 and Figure 6The drive mechanism includes a base 20 and a movable plate 20d, which is slidably mounted on the base 20. There can be one or two movable plates 20d. The base 20 can be a single unit (the base 20 can extend along the length of the panel 10b, or its size can be substantially the same as the movable plate 20d), or it can consist of two separate parts. Thus, the installation relationship between the movable plate 20d and the base 20 can be as follows: one movable plate 20d can be mounted on a single base 20 (if the base 20 extends along the length of the panel 10b, the movable plate 20d can be mounted in the middle of the base 20; if the size of the base 20 is approximately the same as the movable plate 20d, the base 20 can be mounted in the middle of the panel 10b or the frame 10a); or two movable plates 20d can be mounted at opposite ends of a single base 20 along its length, with the two movable plates 20d spaced apart along the length of the panel 10b.

[0065] The following description mainly uses two movable plates 20d installed at both ends of the base 20 along its length as an example.

[0066] Please see 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 to the movable plate 20d. One end of the guide rail 20f is inserted into or snapped onto the movable plate 20d, and the other end is fixed to the movable plate 20d with screws (this facilitates the installation and removal of the guide rail 20f). A guide groove 224 is provided on the base 20. Figure 9 and Figure 10 The guide rail 20f is adapted to the guide groove 224, so 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 groove 224. It should be noted that in the indoor unit of the air conditioner, the drive mechanism may not have a drive source, meaning that the user can manually operate the wind deflector assembly 30 to move up and down. Alternatively, a drive source may be installed in the drive mechanism, and by controlling the drive source, the wind deflector assembly 30 can be automatically raised and lowered.

[0067] Please continue reading. 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 located at both ends of the base 20a. The base 20a has a first side 201 extending from one end to the other end. 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 connector). Thus, in the indoor unit of the air conditioner, the entire base 20 can be roughly an inverted U-shaped structure.

[0068] Because the space between the panel 10b and the frame 10a in the indoor unit of the air conditioner is limited, and both the wind deflector 30 and the base 20a have a certain thickness, if the base 20a and the wind deflector 30 are installed in a stacked manner between the panel 10b and the frame 10a, then a large gap needs to be reserved between the panel 10b and the frame 10a at the beginning of the design, which will affect the overall shape of the indoor unit (the indoor unit will appear thicker). In addition, the width of the air outlet 101 is generally about 15cm, so the width of the wind deflector 30 is generally designed based on the width of the air outlet 101, and its width is not much different from that of the air outlet 101. However, the width of the entire panel 10b is relatively large, so even if the wind deflector 30 and the base 20 are stacked, when the wind deflector 30 is stored inside the panel 10b, a large amount of space remains unused between the panel 10b and the frame 10a, which will also lead to wasted space.

[0069] Therefore, by setting the base 20 as an inverted U-shaped structure, the windproof component 30 can be set at the middle notch of the inverted U-shaped structure, thereby greatly improving the space utilization between the panel 10b and the frame 10a.

[0070] Please continue reading. Figure 11 and Figure 12 The base 20 also includes a motor housing 20c mounted on the side wing 20b. The motor housing 20c is detachably fixed to the side wing 20b, making installation and removal of the motor housing 20c convenient. The motor housing 20c itself has a recess 222 for accommodating the stepper motor 220a, and the side wing 20b has a groove 211 for accommodating the recess 222. The side wing 20b is provided with a insertion hole 214, and one end of the motor housing 20c is provided with a lug 225a. The other end of the motor housing 20c is fixed to the side wing 20b by a connector. Figure 11 and Figure 12 As shown, 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 located next to the screw post 215. When installing the motor box 20c on the side wing 20b, firstly, the lug 225a is inserted into the insertion hole 214, then the recessed part 222 is gradually placed into the groove 211, then the positioning hole 225c and the positioning post 216 are fitted and inserted, and finally, the screw is inserted through the screw hole 225b and screwed into the screw post 215, thereby realizing 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 fit between the groove 211 and the recessed part 222, the installation of the motor box 20c on the side wing 20b is more stable.

[0071] Please refer to the following: Figure 7 , Figure 11and Figure 12 A stepper motor 220a and a first gear 221a are installed inside the motor housing 20c. The stepper motor 220a is fixed in the recess 222 of the motor housing 20c by screws, and the first gear 221a is mounted on the motor shaft of the stepper motor 220a. A first wiring groove 223 is provided on the motor housing 20c. The lug 225a and the insertion hole 214 of the motor housing 20c are located in the extending direction of the first wiring groove 223. A first wire clip 226 is provided at the opening of the first wiring groove 223. The wire 20g connecting the stepper motor 220a passes through the first wiring groove 223, and under the limiting action of the first wire clip 226, the wire 20g is not easily pulled out in the first wiring groove 223.

[0072] Typically, a display module is installed on panel 10b, displaying parameters such as target temperature, air conditioning operating mode, and humidity. Both the display module and the drive mechanism are located inside panel 10b. Please refer to [link / reference needed]. Figure 13 To improve the assembly efficiency of the indoor air conditioning unit, the display module (not shown in the diagram) can be integrated onto the base 20. The wire 20g connecting the stepper motor 220a can be connected to the display module, which in turn connects to the electrical control box. The side wing 20b is a certain distance from the display module; please refer to the following section. Figure 11 and Figure 12To prevent the wire 20g connecting the stepper motor 220a from being exposed after exiting the first wiring groove 223, in one embodiment, a second wiring groove 202 is provided on the base 20a. The second wiring groove 202 extends from the side wing 20b toward the display box. The wire 20g exits from the first wiring groove 223 and enters the second wiring groove 202, and then passes through the display box. Since the first wiring groove 223 extends vertically and the second wiring groove 202 extends horizontally, if the wire 20g directly enters the second wiring groove 202 after exiting the first wiring groove 223, it will be affected by the second wiring groove 202 and shift towards the second wiring groove 202. Over time, the wire 20g may come out of the first wiring groove 223, and may also come out of the second wiring groove 202. Therefore, in one embodiment, a wire-passing hole 203 is provided on the base 20a, and the wire-passing hole 203 is located between the first wiring groove 223 and the second wiring groove 202. In this way, the wire-passing hole 203 is relatively close to the first wiring groove 223, which can reduce the offset force of the wire 20g when it is detached from the first wiring groove 223. Furthermore, since there is also a certain distance between the wire-passing hole 203 and the first wiring groove 223, if this distance is too long, the wire 20g will be too long. The long wire 20g will fall downward between the wire-passing hole 203 and the second wiring groove 202, and may eventually fall into the notch of the inverted U-shaped base 20, thereby interfering with the up and down sliding of the wind deflector assembly 30, or 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, thereby seriously affecting the user experience. To avoid this situation, in another embodiment, a wire clamping plate 204 is also provided on the base 20a. The wire clamping plate 204 is located between the wire hole 203 and the second wiring groove 202. The lower end of the wire clamping plate 204 is connected to the base 20a and extends upward. The wire clamping plate 204 can clamp the wire 20g onto the base 20a, and also support the wire 20g, so that even if the wire 20g is slightly long, it will not fall into the notch of the base 20.

[0073] The main function of the second wiring channel 202 is to house and conceal the wire 20g. In one embodiment, to facilitate the installation of the wire 20g in the second wiring channel 202, the opening of the second wiring channel 202 faces the panel 10b, and a second wire clip 205 is provided at the opening of the second wiring channel 202. The second wiring channel 202 has two side walls extending in the left-right direction. The second wire clip 205 is connected to one of the side walls, and the other side wall is provided with a clearance notch 206 corresponding to the second wire clip 205. During wiring, the wire 20g is bypassed by the clearance notch 206, making both wiring and removal from the second wiring channel 202 more convenient.

[0074] In the two side wings 20b of the base 20, the opening of the first wiring groove 223 on one side wing 20b faces the other side wing 20b. This facilitates the concealment of the wire 20g, and the wire 20g cannot be seen by the user when observing the base 20 from the front or the back.

[0075] In addition, the motor box 20c is slidably engaged with the guide rail 20f. The motor box 20c is provided with the aforementioned guide groove 224. The opening direction of the guide groove 224 is opposite to the opening direction of the first wiring groove 223. Because the guide groove 224 is laterally open (in the indoor unit of the air conditioner, the opening of the guide groove 224 faces left or right), the guide groove 224 has a limiting effect on the guide rail 20f, which can restrict the guide rail 20f from moving forward or backward. Since both the guide rail 20f and the guide groove 224 extend in the vertical direction, after the guide rail 20f is engaged with the guide groove 224, the guide rail 20f can only slide in the vertical direction within the guide groove 224.

[0076] Please continue reading. Figures 7 to 10 A rack is provided on the guide rail 20f, which meshes with the first gear 221a. When the stepper motor 220a is working, the guide rail 20f can be moved up and down through the first gear 221a. Please refer to the following: Figure 18 The guide rail 20f includes a rack plate 241 and a track plate 242, with a gap between them. The rack plate 241 is provided with a rack that meshes with the first gear 221a. The track plate 242 is inserted into the guide groove 224. To reduce the sliding resistance between the guide rail 20f and the guide groove 224, the track plate 242 is provided with a plurality of first columnar bodies 243. One side wall of each first columnar body 243 protrudes from one side of the track plate 242, and the other side wall protrudes from the other side of the track plate 242. Thus, when the track plate 242 is inserted into the guide groove 224, the side wall of the first columnar body 243 abuts against the inner wall of the guide groove 224, thereby reducing friction and making the sliding of the guide rail 20f and the guide groove 224 smoother.

[0077] The vertical movement of the aforementioned movable plate 20d can be achieved by one guide rail 20f cooperating with one guide groove 224, or by two guide rails 20f cooperating with two guide grooves 224. Considering that the panel 10b of the wall-mounted air conditioner indoor unit extends in the left-right direction, in order to make the air deflector assembly 30 slide more smoothly, it is a preferred embodiment to provide guide rails 20f on both movable plates 20d and guide grooves 224 on both side wings 20b. In addition, sliding drive assemblies are also provided on both side wings 20b.

[0078] Please see Figure 6 , Figure 14 and Figure 15 To facilitate smoother sliding of the windshield assembly 30, in a preferred embodiment, a guide rail 20e is provided on the base 20, and a guide groove 251a adapted to the sliding of the guide rail 20e is provided on the movable plate 20d. There can be one or two guide rails 20e. The main function of the guide rail 20e is to improve the stability of the sliding of a single movable plate 20d. The guide rail 20e extends in the vertical direction, and it is spaced apart from the guide rails 20f. In embodiments where only one guide rail 20e is installed on the base 20, the installation position of the guide rail 20e can be varied. For example, one guide rail 20f can be located between the guide rail 20e and another guide rail 20f, or the guide rail 20e can be located between two guide rails 20f. Regarding the implementation of installing two correction guide rails 20e on the base 20, there are multiple ways to install the correction guide rails 20e. For example, both correction guide rails 20e can be located between the two guide rails 20f, or the correction guide rails 20e and the guide rails 20f can be arranged alternately, or the two guide rails 20f can be located between the two correction guide rails 20e.

[0079] The following content mainly describes the installation of the alignment guide rail 20e.

[0080] Considering that when the windshield assembly is connected to the movable plate 20d, it mainly connects to the inner side of the movable plate 20d (near the notch in the middle of the inverted U-shaped base 20), so the inner side of the movable plate 20d needs to bear the weight of the windshield assembly 30, while the outer side of the movable plate 20d tends to tilt inward.

[0081] The wind deflector assembly 30 extends along the length of the panel 10b (the wind deflector assembly 30 is used to block the air outlet 101, which extends in the left and right direction). The wind deflector assembly 30 is relatively long (about 0.6m to 1m). There is a certain tolerance in the installation of such a long wind deflector assembly 30 on the movable plate 20d. 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, if the strokes of the two ends of the wind deflector assembly 30 are inconsistent (one end is high and the other end is low), the movable plate 20d will get stuck, and the wind deflector assembly 30 will not be able to move up and down.

[0082] The setting of the correction guide rail 20e provides more tracks for the movement of the windshield assembly 30, making the movement of the windshield assembly 30 more stable. On the other hand, after the guide slide rail 20f and the correction guide rail 20e are combined, when the movable plate 20d slides up and down, the guide slide rail 20f and the correction guide rail 20e restrict each other, thereby reducing the left and right swing amplitude when the movable plate 20d moves, and thus reducing the problem of inconsistent stroke at both ends when the windshield assembly 30 moves up and down.

[0083] Since the connection between the windshield assembly 30 and the movable plate 20d is biased towards the inside of the movable plate 20d, in one embodiment, please refer to... Figure 6 , Figure 14 , Figure 16 and Figure 17 To improve the correction effect of the correction guide 20e, the correction guide 20e is installed on the inner side of the side wing 20b. Figure 14 and Figure 16 It should be noted that the side wing 20b has an outer side facing away from the base 20a and an inner side opposite to the outer side. In the figure, the side wing 20b is integrally formed with the base 20a. Part of the inner side of the side wing 20b overlaps with the base 20a. This part of the inner side is located at the junction of the side wing 20b and the base (for ease of description, this inner side is defined as X1). Another part of the inner side of the side wing 20b protrudes from the first side wing 201 (this inner side is defined as X2). The correction guide rail 20e can be installed at any position on the inner side of the side wing 20b, as long as it can cooperate with the sliding of the movable plate 20d. In the embodiment where both side wings 20b are equipped with correction guide rails 20e, one correction guide rail 20e can be installed at X1 or X2. Of course, both correction guide rails 20e can be installed at X1 or both at X2. To ensure smoother operation of the movable plate 20d, the two correction guide rails 20e are staggered in the direction perpendicular to the sliding of the movable plate 20d (i.e., one correction guide rail 20e is installed at X1, and the other at X2). With this arrangement, the two correction guide rails 20e provide mutual oblique support through the windbreak assembly 30, and the two guide rails 20f further guide the movement of the two movable plates 20d. This arrangement ensures that the line connecting the midpoints of the two correction guide rails 20e, the extension direction of the correction guide rails 20e, and the two movable plates 20d always form a triangle, thus enhancing stability.

[0084] To facilitate the assembly and fixing of the alignment guide rail 20e, in one embodiment, side plates 212 and 212' are formed on the inner side of the side wing 20b. Figure 7 , Figure 12 and Figure 14The correction guide rail 20e is engaged with the side plate 212. Specifically, the correction guide rail 20e includes a correction groove 231a and a correction rib 232a provided in the correction groove 231a. The correction groove 231a is sleeved on the side plate 212 (before the correction groove 231a is fixed with the side wing 20b, the correction groove 231a can slide up and down along the side plate 212). The movable plate 20d is provided with a guide groove 251a, which slides in cooperation with the correction rib 232a. On the same side wing 20b, the opening of the correction groove 231a faces the guide rail 20f located on the side wing 20b, and the correction rib 232a is located on the side of the correction groove 231a facing away from the guide rail 20f of the side wing 20b. In this way, in the front-back direction, the guide groove 251a can hold and limit the correction rib 232a.

[0085] Furthermore, to facilitate the assembly and disassembly of the alignment guide 231a, the alignment guide 231a can be detachably fixed to the side wing 20b. In one embodiment, the side plate 212 is provided with a fixing hole 212a, and the inner wall of the alignment guide 231a is provided with a locking platform 236 corresponding to the position of the fixing hole 212a. Thus, when installing the alignment guide rail 20e, after the locking platform 236 is engaged with the fixing hole 212a, the alignment guide 231a can be firmly fixed to the side plate 212 (in the vertical direction, the alignment guide 231a and the side plate 212 can remain relatively fixed). To ensure more stable installation of the alignment guide rail 20e, a first fixing groove 212b (located at the lower end of the side wing 20b, in the shape of a notch) is provided on the side wing 20b, inside the side plate 212. The alignment sliding groove 231a has two sides extending along the sliding direction of the side plate 212. One side is provided with a first fastening platform 234 for fastening the side plate 212, and the other side is provided with a second fastening platform 235 that cooperates with the first fixing groove 212b. Thus, the first fastening platform 234 can fasten one side of the side plate 212, thereby keeping one side wall of the alignment sliding groove 231a relatively fixed to the side plate 212, and the second fastening platform 235 can fix the other side wall of the alignment sliding groove 231a to the side plate 212. Further details can be found in the following sections. Figure 14 The first side 201 of the base 20a is provided with a stop 213, and a second fixing groove 213a is formed between the stop 213 and the side plate 212. The correction slide groove 231a is inserted into the second fixing groove 213a. In order to facilitate the assembly of the correction guide rail 20e, the clamping table 236 and the second fastening table 235 are provided at the end of the correction slide groove 231a away from the base 20a.

[0086] Furthermore, please refer to Figure 15In order to facilitate the installation and disassembly of the correction slide 231a, the above-mentioned card platform 236 is arranged in a triangular shape. That is, when the upper end of the correction groove 231a is aligned with the lower end of the side plate 212, the correction groove 231a is pushed upward, and the first latching platform 234 latches with one side of the side plate 212. When the locking platform 236 abuts against the lower end of the side plate 212, the correction groove 231a is pushed upward with force. At this time, since the locking platform 236 is triangularly set and one side of the locking platform 236 is inclined, under the guiding action of the inclined surface, the locking platform 236 gradually passes the lower end of the side plate 212. Under the abutting action of the locking platform 236 and the side plate 212, the side plate 212 and / or the correction guide rail 20e deforms until the locking platform 236 is inserted into the fixing hole 212a. Then the side plate 212 and / or the correction guide rail 20e returns to its original deformation, so that the bottom of the correction groove 231a can be firmly attached to the side plate 212. In summary, the correction slide 231a securely fixes the correction guide rail 20e to the side plate 212 through four fixing methods (the upper end of the correction slide 231a is inserted into the second fixing groove 213a, the first fastening platform 234 is fastened to the side plate 212, the second fastening platform 235 is fastened to the first fixing groove 212b, and the locking platform 236 is locked into the fixing hole 212a).

[0087] Please continue reading. Figure 14 and Figure 15 The correction rib 232a is roughly flush with one side of the correction groove 231a. The correction rib 232a is inserted into the guide groove 251a. In order to reduce the friction between the correction rib 232a and the inner wall of the guide groove 251a, a plurality of second columnar bodies 233 are provided on the correction rib 232a. That is, the guide groove 251a has two opposite side walls. At least two arc-shaped protrusions 233a (arc-shaped protrusions 233a are the side walls of the second columnar bodies 233) are provided on both sides of the correction rib 232a. The arc-shaped protrusions 233a on both sides of the correction guide rail 20e respectively abut against the two side walls of the guide groove 251a.

[0088] The two correction guides 20e can have the same structure or different structures. See another embodiment for details. Figure 16 and Figure 17 The correction guide rail 20e includes a correction groove 231b. The movable plate 20d is provided with a guide part 251b, which is located inside the side wing 20b (approximately at the junction with the base 20a. The base 20a and the side wing 20b may not have a clear junction line. They may be integrally formed or assembled). The guide part 251b is slidably disposed in the correction groove 231b.

[0089] Please see Figure 17To further reduce the frictional resistance between the correction groove 231b and the guide portion 251b, the correction guide rail 20e also includes a correction rib 232b provided on the inner wall of the correction groove 231b. The correction rib 232b abuts against the guide portion 251b. The correction rib 231b extends in the vertical direction, and the contact area between it and the guide portion 251b is small, resulting in smoother sliding.

[0090] Since the guide rail 20e needs to ensure the sliding trajectory of the movable plate 20d, the material of the guide rail 20e can be set as a rigid material, such as stainless steel or aluminum alloy. In addition, since the guide rail 20e slides in the guide groove 251a for a long time, in order to make the guide rail 20e slide more smoothly, the material of the guide rail 20e can be a self-lubricating wear-resistant material.

[0091] When the wind deflector assembly 30 is a vortex module, the fan blade 301 installed inside the wind deflector assembly 30 can be rotated by active drive. In one embodiment, a fan blade 301 drive assembly is also provided on one of the movable plates 20d. The fan blade 301 drive assembly is connected to the fan blade 301 and is used to drive the fan blade 301 to rotate. The fan blade 301 drive assembly includes a drive motor 220b and a second gear 221b, which is connected to the fan blade 301 in a transmission manner.

[0092] Please see Figure 11 , Figure 12 and Figure 18 The movable plate 20d moves up and down, and the fan blade 301 drive assembly moves along with it. The motor cable 20g connecting the drive motor 220b also moves along with it, so the motor cable 20g needs to have a certain redundant length. The base 20 has a cable tray 227 for the motor cable 20g. The motor cable 20g passes through the cable tray 227 via the inlet 228 and then connects to the display box. Because the opening of the inlet 228 is approximately at a 90° angle to the vertical direction, the redundant motor cable 20g, after exiting from the inlet 228, is prone to large-angle bending during movement. Over time, this can cause fatigue and damage to the motor cable 20g. This affects the operation of the wind deflector assembly 30, reduces the lifespan of the indoor air conditioning unit, and may even lead to safety accidents.

[0093] In addition, the closer the wire channel 227 is to the drive motor 220b, the more likely the motor wire 20g located between them will be bent at a large angle. Therefore, the wire channel 227 and the drive motor 220b should be spaced apart in the length direction of the panel 10b. The longer the distance, the less likely the motor wire 20g will be bent at a large angle.

[0094] In one embodiment, please refer to Figures 19 to 21To prevent the long motor cable 20g from bending at a large angle, a first guide portion 229 is provided at the cable inlet 228 of the cable tray 227. The first guide portion 229 can extend upward or downward from the cable inlet 228. The inclined extension can be along a straight line or along an arc. If the first guide portion 229 extends downward from the cable inlet 228, then when the movable plate 20d moves downward, the first guide portion 229 will have a certain load-bearing capacity for the motor cable 20g, and can also reduce the bending angle of the motor cable 20g at the end of the first guide portion 229. If the first guide section 229 extends upward from the inlet 228, then when the movable plate 20d moves upward, under the action of the first guide section 229, the motor wire 20g, after being led out from the inlet 228, is guided by the first guide section 229, and under the action of the motor wire 20g's own weight, the motor wire 20g will not bend excessively.

[0095] If there is only one first guide section 229, the preferred arrangement is to extend the first guide section 229 downward from the inlet 228.

[0096] Considering that the guiding effect of a single first guide portion 229 is not as good as that of two first guide portions 229, in one embodiment, two first guide portions 229 are provided at the cable inlet 228, one first guide portion 229 bending downward from the cable inlet 228 and the other first guide portion 229 bending upward from the cable inlet 228. In this way, whether the movable plate 20d moves upward or downward, the first guide portion 229 can guide the long motor, thereby avoiding an excessively large bending angle of the motor cable 20g.

[0097] Additionally, define the length s1 of the first guide portion 229 extending downward from the inlet 228, and define the length s2 of the first guide portion 229 extending upward from the inlet 228. It is preferable that s1 is greater than s2. This is because when the motor wire 20g moves, it will be subject to its own force. When the motor wire 20g comes into contact with the end of the downwardly extending first guide portion 229, it is more likely to bend at a large angle. Therefore, if the length of the first guide portion 229 itself is increased, the tangent at the end of the first guide portion 229 may coincide with (or substantially coincide with) the extension direction of the motor wire 20g. In this way, the extension of the wire 20g after passing through the first guide portion 229 is smoother.

[0098] In another preferred embodiment, to improve the guiding effect of the two first guide portions 229, a gap is formed between the two first guide portions 229, which is flared out in the direction away from the inlet 228. On the one hand, the two first guide portions 229 are arc-shaped, and the gap between them is flared out, so that the included angle of the tangents of the two first guide portions 229 will increase as it moves away from the inlet 228, thereby reducing the large-angle bending of the motor wire 20g.

[0099] The large-angle bend of the motor wire 20g depends not only on the position of the inlet 228, but also on the exit angle of the drive motor 220b itself. In one embodiment, a second guide portion 261 is provided on the movable plate 20d. The second guide portion 261 is located around the drive motor 220b. The second guide portion 261 extends downward towards the side where the wire groove 227 is located, or the second guide portion 261 extends upward towards the side where the wire groove 227 is located.

[0100] Of course, similar to the case of the first guide section 229, it is preferable to have two second guide sections 261. That is, two second guide sections 261 are provided on the movable plate 20d, with the two second guide sections 261 spaced apart, one second guide section 261 bending downward and the other second guide section 261 bending upward. The bending effect of the second guide section 261 can be the same as that of the first guide section 229.

[0101] Furthermore, since the motor wire 20g is typically soldered to the motor interface, if the interface where the motor wire 20g connects to the motor is subjected to tensile force, the solder joint at the interface can easily loosen, leading to poor contact with the drive motor 220b. In severe cases, this can directly cause the motor wire 20g to detach from the motor. Therefore, in one embodiment, a winding portion 262 is provided between the two second guide portions 261, spaced apart from the two second guide portions 261. With the winding portion 262 provided, the motor wire 20g can be wound around the winding portion 262. Even under tensile force, the motor wire 20g can distribute most of the tensile force to the winding portion 262, thereby preventing the solder joint between the motor wire 20g and the motor interface from loosening.

[0102] There are several ways for the motor wire 20g to be routed between the two second guide sections 261. For example, the gap between the winding section 262 and one of the second guide sections 261 near the drive motor 220b can be defined as gap one, and the gap between the winding section 262 and the other second guide section 261 can be defined as gap two. After the motor wire 20g is led out from the drive 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 guide sections 229. Alternatively, 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 guide sections 229. That is, the motor wire 20g connected to the drive motor 220b is wound around the outer periphery of the winding section 262 and passes through the gap between the two first guide sections 229 into the wire groove 227. With this winding method, if the motor wire 20g suddenly receives a large pulling force when the movable plate 20d moves up and down, the pulling force can be almost entirely transferred to the winding part 262 in an instant. Therefore, the winding part 262 provides excellent protection for the connection of the motor wire 20g.

[0103] In embodiments without the winding portion 262, the winding method can also be that the motor wire 20g, after being led out from the motor, wraps around the outer periphery of the drive motor 220b and passes through the gap between the two second guide portions 261 and the gap between the two first guide portions 229 into the wire groove 227. In other words, the outer wall of the drive motor 220b replaces the function of the winding portion 262. When the motor wire 20g is subjected to a sudden pulling force, this pulling force can be instantly offset by the frictional force generated between the drive motor 220b and the motor wire 20g, thereby protecting the connection of the motor wire 20g.

[0104] The movable plate 20d has two extreme positions: the uppermost and the lowermost. The travel distance between these two extreme positions is the maximum travel distance of the movable plate 20d. The length of the redundant motor wire 20g between the inlet 228 and the winding section 262 must always be greater than the straight-line distance between the inlet 228 and the winding section 262; otherwise, the motor wire 20g will be subjected to severe tensile force during the up-and-down movement of the movable plate 20d. Furthermore, the redundant motor wire 20g between the inlet 228 and the winding section 262 should not be too long, as an excessively long motor wire 20g will become tangled and knotted between the inlet 228 and the winding section 262, easily leading to premature fatigue and damage. Therefore, the optimal approach is to ensure that the length of the motor wire 20g between the inlet 228 and the winding section 262 is slightly greater than the straight-line distance between the inlet 228 and the winding section 262. For example, if the straight-line distance between the inlet 228 and the winding section 262 is L1, and the length of the motor wire 20g between the inlet 228 and the winding section 262 is L2, then 1.1 × L1 ≤ L2 ≤ 1.3 × L2. Of course, since the movable plate 20d has two extreme positions (upper and lower), in order to simultaneously satisfy the requirement that the length of the motor wire 20g between the inlet 228 and the winding section 262 is just slightly greater than the straight-line distance between the inlet 228 and the winding section 262 when the movable plate 20d is in either of these extreme positions, in this embodiment, the inlet 228 can be positioned at the middle of the maximum stroke of the movable plate 20d, that is, the inlet 228 can be approximately centered on the maximum stroke of the movable plate 20d.
