Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.

In addition, the descriptions related to "first", "second", etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

The invention provides a driving mechanism and an air conditioner provided with the same. The air conditioner can be a split type or an integrated type. The split type air conditioner can be a wall-mounted air conditioner, a floor type air conditioner, an air duct machine, a ceiling type air conditioner and the like. For the integrated air conditioner, a window air conditioner, a mobile air conditioner, etc. may be used.

Referring to fig. 1 to 3, the driving mechanism is specifically described by taking a case of being installed in an indoor unit of a wall-mounted air conditioner as an example. The indoor unit of the air conditioner comprises an outer shell 10, wherein the outer shell 10 comprises a face frame 10a and a panel 10b installed on the face frame 10a, an air outlet 101 is arranged on the face frame 10a, and the air outlet 101 is generally positioned below the panel 10 b. The panel 10b is provided with a driving mechanism inside, the driving mechanism is connected with the wind shielding assembly 30, and the wind shielding assembly 30 is slidably mounted on the driving mechanism in the up-down direction, so that the wind shielding assembly 30 has a first state of being received inside the housing 10b and a second state of being shielded at the front side of the indoor wind outlet 101. Therefore, the switching of the air outlet mode is realized.

It should be noted that there are various forms of the wind shielding assembly 30, and the wind shielding assembly 30 is a baffle, a micro-perforated plate or a cyclone module, where the baffle is used to block the airflow of the wind outlet 101 from blowing out to the front side, the micro-perforated plate is used to scatter the airflow and blow out, and the cyclone module is used to guide the airflow to rotate and blow out. The baffle is blocked at the front side of the air outlet 101, so that the air outlet direction of the air outlet 101 can be changed, and the air outlet 101 supplies air downwards; the microporous plate is blocked at the front side of the air outlet 101, so that the airflow can pass through the micropores, the airflow is scattered, and the air speed and the air quantity are reduced; for the rotational flow module, the air passing hole 300 is formed in the rotational flow module, the fan blade 301 is arranged in the air passing hole 300, the fan blade 301 can rotate actively or passively, when the air flow is blown out from the air outlet 101 through the air passing hole 300, the fan blade 301 can send out the air flow in a rotating mode no matter the fan blade rotates actively or rotates passively, the rotating air flow is mixed with the ambient air after being blown out, and therefore the blown air flow is softer.

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

Referring to fig. 4, 5 and 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. The movable plate 20d may be one or two. The base 20 may be a single body (the base 20 may extend in the longitudinal direction of the panel 10b, or may have a size substantially identical to that of the movable plate 20 d), or the base 20 may include two separate bodies. Thus, the movable plate 20d and the base 20 can be mounted in a manner that one movable plate 20d is mounted on one integral base 20 (for the case that the base 20 extends along the length direction of the panel 10b, the movable plate 20d can be mounted at the middle position of the base 20; for the case that the size of the base 20 is approximately consistent with the movable plate 20d, the base 20 can be mounted at the middle position of the panel 10b or the panel frame 10 a); alternatively, the two movable plates 20d may be respectively installed at two ends of the integral base 20 in the length direction, and the two movable plates 20d may be arranged at intervals in the length direction of the panel 10 b.

The following description will mainly describe the two movable plates 20d as an example mounted on both ends of the base 20 in the longitudinal direction.

Referring to fig. 7, 8, 9 and 10, the movable plate 20d is provided with a guide rail 20f, the guide rail 20f is detachably fixed on the movable plate 20d, one end of the guide rail 20f is inserted into or fastened to the movable plate 20d, and the other end is fixed on the movable plate 20d by a screw (so as to facilitate the installation and the detachment of the guide rail 20 f). The base 20 is provided with a guide sliding groove 224 (fig. 9 and 10), and the guide sliding rail 20f is adapted to the guide sliding groove 224, so that the movable plate 20d can slide up and down relative to the base 20 by the cooperation of the guide sliding rail 20f and the guide sliding groove 224. In the air conditioning indoor unit, the driving source may not be provided in the driving mechanism, that is, the user may manually operate the wind shielding assembly 30 to move up and down. A driving source may be provided in the driving mechanism, and the automatic elevation of the wind shielding assembly 30 may be realized by controlling the driving source.

With continued reference to fig. 6 and 7, the base 20 is basically constructed as follows: the air conditioning indoor unit comprises a base 20a and two side wings 20b, wherein the two side wings 20b are respectively arranged at two ends of the base 20a, the base 20a is provided with a first side 201 extending towards the other end along one end of the base, and the two side wings 20b are protruded from the first side 201 (the base 20a and the side wings 20b can be integrally formed or connected through connecting pieces), so that in the air conditioning indoor unit, the whole base 20 can be of an approximately inverted U-shaped structure.

Because the space between the panel 10b and the face frame 10a in the air conditioning indoor unit is limited, and the wind shielding assembly 30 and the base 20a both have a certain thickness, if the base 20a and the wind shielding assembly 30 are installed between the panel 10b and the face frame 10a in a laminated manner, a large gap needs to be reserved between the panel 10b and the face frame 10a at the beginning of design, which affects the overall shape of the air conditioning indoor unit (the air conditioning indoor unit is thicker overall). In addition, since the width of the outlet 101 is generally about 15cm, the width of the wind shielding assembly 30 is generally designed according to the width of the outlet 101, and the width of the wind shielding assembly is not much different from the width of the outlet 101, but the width of the whole panel 10b is large, so that even if the wind shielding assembly 30 and the base 20 are stacked, when the wind shielding assembly 30 is accommodated inside the panel 10b, a large space is left between the panel 10b and the face frame 10a, and thus, the space is wasted.

Therefore, after the base 20 is configured as an inverted U-shaped structure, the wind shielding assembly 30 can be disposed at the middle gap of the inverted U-shaped structure, so that the space utilization rate between the panel 10b and the face frame 10a is greatly improved.

With continued reference to fig. 11 and 12, the base 20 further includes a motor case 20c mounted on the side wings 20b, and the motor case 20c is detachably fixed to the side wings 20b, so that the motor case 20c is convenient to mount and dismount. The motor case 20c is formed with a recess 222 for accommodating the stepping motor 220a, the wing 20b is formed with a groove 211 for accommodating the recess 222, the wing 20b is provided with a plug-in hole 214, one end of the motor case 20c is provided with a lug 225a, and the other end of the motor case 20c is fixed on the wing 20b through a connecting piece. As shown in fig. 11 and 12, the other end of the motor case 20c is provided with a screw hole 225b and a positioning hole 225c, the wing 20b is provided with a screw post 215 corresponding to the position of the fixing hole 212a, and a positioning post 216 located beside the screw post 215, when the motor case 20c is mounted on the wing 20b, the lug 225a is firstly inserted into the insertion hole 214, then the recess 222 is gradually placed in the groove 211, then the positioning hole 225c and the positioning post 216 are inserted in an adaptive manner, and finally a screw is inserted into the screw hole 225b and screwed into the screw post 215, so that the mounting of the motor case 20c is realized. After the motor box 20c is installed on the side wing 20b, on one hand, both ends of the motor box 20c are fixed, and on the other hand, the installation of the motor box 20c on the side wing 20b is more stable due to the matching of the groove 211 and the recess 222.

Referring to fig. 7, 11 and 12, a stepping motor 220a and a first gear 221a are installed in the motor case 20c, the stepping motor 220a is fixed in the recess 222 of the motor case 20c by screws, and the first gear 221a is installed on a motor shaft of the stepping motor 220 a. The motor box 20c is provided with a first wiring groove 223, the lug 225a and the plug hole 214 of the motor box 20c are located in the extending direction of the first wiring groove 223, a first wire clamp 226 is arranged at the notch of the first wiring groove 223, the lead 20g connected with the stepping motor 220a penetrates into the first wiring groove 223, and under the limiting effect of the first wire clamp 226, the lead 20g is not easy to be separated out from the first wiring groove 223.

In general, the panel 10b is provided with display modules for displaying parameters such as target temperature, air-conditioning operation mode, humidity, etc.; referring to fig. 13, in order to improve the assembly efficiency of the indoor unit of the air conditioner, the display module (not shown) may be integrated on the base 20, and the lead 20g connected to the stepping motor 220a may be connected to the display module and then connected to the electronic control box through the display module. With reference to fig. 11 and 12, in order to avoid the lead 20g connected to the stepping motor 220a from being exposed after being led out from the first wire slot 223, in an embodiment, the base 20a is provided with a second wire slot 202, the second wire slot 202 extends from the side wing 20b toward the display box, and the lead 20g passes out of the first wire slot 223, enters the second wire slot 202, and then passes through the display box. Because the first wiring groove 223 extends in the up-down direction, and the second wiring groove 202 extends in the left-right direction, if the wire 20g is led out from the first wiring groove 223 and then directly enters the second wiring groove 202, the wire 20g will deviate towards the second wiring groove 202 in the first wiring groove 223 due to the influence of the second wiring groove 202, and after a long time, the wire 20g may be pulled out from the first wiring groove 223, and further the wire 20g may be pulled out from the second wiring groove 202. In view of this, in one embodiment, the base 20a has a wire hole 203, and the wire hole 203 is located between the first wire groove 223 and the second wire groove 202. In this manner, the wire passing hole 203 is closer to the first wire running groove 223, and the force of the deviation of the wire 20g from the first wire running groove 223 can be reduced. Further, since there is a certain distance between the wire passing hole 203 and the first wire trough 223, if the distance is too long, the wire 20g is long, and the long wire 20g may fall down from between the wire passing hole 203 and the second wire trough 202, and finally may fall down to the gap of the inverted U-shaped base 20, so as to interfere with the up-and-down sliding of the wind shielding assembly 30, and even cause a safety accident; on the other hand, the wire 20g may also fall from below the panel 10b to the outlet 101, thereby seriously affecting the user experience. In order to avoid this, in another embodiment, a wire-pressing plate 204 is further disposed on the base 20a, the wire-pressing plate 204 is located between the wire-passing hole 203 and the second wire-passing groove 202, and the lower end of the wire-pressing plate 204 is connected to the base 20a and extends upward. The wire pressing plate 204 can press the lead 20g on the base 20a, and can also bear the lead 20g, so that the lead 20g does not fall to the notch of the base 20 even if the lead 20g is slightly long.

The primary function of the second cabling channel 202 is to house and conceal the wires 20 g. In an embodiment, to facilitate installation of the wire 20g in the second cabling channel 202, the notch of the second cabling channel 202 faces the panel 10b, and a second line card 205 is disposed at the notch of the second cabling channel 202. The second wire trough 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 an avoidance gap 206 corresponding to the second wire clip 205. During wiring, the second line card 205 is bypassed by avoiding the gap 206, so that the wire 20g can be conveniently wired or detached from the second cabling trough 202.

The notch of the first routing groove 223 on one of the two side wings 20b of the base 20 is oriented toward the other side wing 20b, thus facilitating the concealment of the lead 20g, and the lead 20g is not visible to the user when the base 20 is viewed from the front side or the rear side.

In addition, the motor case 20c is slidably engaged with the guide sliding rail 20f, the guide sliding groove 224 is disposed on the motor case 20c, the opening direction of the guide sliding groove 224 is opposite to the opening direction of the first wire groove 223, and since the guide sliding groove 224 is opened laterally (in the air conditioning indoor unit, the opening of the guide sliding groove 224 is left or right), the guide sliding groove 224 has a limiting function on the guide sliding rail 20f, and can limit the forward or backward displacement of the guide sliding rail 20f, and since the guide sliding rail 20f and the guide sliding groove 224 are both extended in the up-down direction, after the guide sliding rail 20f is engaged with the guide sliding groove 224, the guide sliding rail 20f can only slide in the up-down direction in the guide sliding groove 224.

Referring to fig. 7 to 10, the guiding rail 20f is provided with a rack, the rack is engaged with the first gear 221a, and when the stepping motor 220a works, the first gear 221a can drive the guiding rail 20f to move up and down. Referring to fig. 18, the guide rail 20f includes a rack plate 241 and a rail plate 242, a gap is formed between the rack plate 241 and the rail plate 242, a rack engaged with the first gear 221a is provided on the rack plate 241, the rail plate 242 is inserted into the guide chute 224, and in order to reduce the sliding fit resistance between the guide rail 20f and the guide chute 224, the rail plate 242 is provided with a plurality of first cylindrical bodies 243, and a side wall of the first cylindrical body 243 protrudes from one side surface of the rail plate 242 and the other side wall protrudes from the other side surface of the rail plate 242, so that when the rail plate 242 is inserted into the guide chute 224, the side wall of the first cylindrical body 243 is abutted against the inner wall of the guide chute 224, thereby reducing the friction force and making the sliding between the guide rail 20f and the guide chute 224 smoother.

The moving up and down of the movable plate 20d may be realized by matching one guide rail 20f with one guide chute 224, or by matching two guide rails 20f with two guide chutes 224. Considering that the panel 10b of the wall-mounted air conditioning indoor unit extends in the left-right direction, in order to make the wind shielding assembly 30 slide more smoothly, it is preferable to provide the guide rails 20f on both the movable plates 20d and the guide chutes 224 on both the side wings 20 b. In addition, a sliding drive assembly is also provided on each of the two side wings 20 b.

Referring to fig. 6, 14 and 15, in order to make the wind shielding assembly 30 slide more smoothly, in a preferred embodiment, the base 20 is provided with a deviation-correcting guide rail 20e, and the movable plate 20d is provided with a guide groove 251a adapted to the deviation-correcting guide rail 20e in a sliding manner. The number of the deviation correcting guide rails 20e may be one or two. The deviation correcting guide rail 20e mainly functions to improve the stability of the sliding of the single movable plate 20 d. The deviation correcting guide rail 20e extends in the up-down direction, and the deviation correcting guide rail 20e and the guide rail 20f are spaced apart from each other. For the embodiment of installing only one deviation correcting guide rail 20e on the base 20, the installation position of the deviation correcting guide rail 20e can be various, for example, one of the guide rails 20f is located between the deviation correcting guide rail 20e and the other guide rail 20f, or the deviation correcting guide rail 20e is located between the two guide rails 20 f. For the implementation of installing two deviation-correcting guide rails 20e on the base 20, there are various installation manners of the deviation-correcting guide rails 20e, for example, the two deviation-correcting guide rails 20e are both located between the two guide rails 20f, the deviation-correcting guide rails 20e and the guide rails 20f are alternately arranged, or the two guide rails 20f are located between the two deviation-correcting guide rails 20 e.

The following description will mainly describe the installation of the deviation guide 20 e.

Considering that the wind shielding set is connected to the movable plate 20d, the inner side of the movable plate 20d (near the gap in the middle of the inverted U-shaped base 20) is mainly connected, so that the inner side of the movable plate 20d needs to bear the weight of the wind shielding assembly 30, and the outer side of the movable plate 20d tends to incline inwards.

The wind shielding assembly 30 extends along the length direction of the panel 10b (the wind shielding assembly 30 is used for shielding the wind outlet 101, and the wind outlet 101 extends along the left-right direction), the wind shielding assembly 30 is relatively long (about 0.6 m-1 m), a certain tolerance exists in the installation of the wind shielding assembly 30 with the length on the movable plate 20d, and in addition, the base 20 and the movable plate 20d are plastic pieces, so when the movable plate 20d moves in the up-down direction, once the strokes of two ends of the wind shielding assembly 30 are inconsistent (one end is high and the other end is low), the movable plate 20d is blocked, and the wind shielding assembly 30 cannot move up and down.

The arrangement of the deviation-correcting guide rail 20e provides more tracks for the movement of the wind shielding assembly 30, so that the wind shielding assembly 30 moves more stably, and after the guide slide rail 20f and the deviation-correcting guide rail 20e are combined, the guide slide rail 20f and the deviation-correcting guide rail 20e are limited when the movable plate 20d slides up and down, so that the left-right swing amplitude of the movable plate 20d during movement can be reduced, and the problem of inconsistent strokes at two ends caused by the up-down movement of the wind shielding assembly 30 is further reduced.

Since the connection point of the wind shielding assembly 30 and the movable plate 20d is biased to the inner side of the movable plate 20d, in an embodiment, referring to fig. 6, 14, 16 and 17, in order to make the deviation rectifying effect of the deviation rectifying guide 20e better, the deviation rectifying guide 20e is installed on the inner side of the side wing 20b (fig. 14 and 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, and a part of the inner side of the side wing 20b is integrally formed with the base 20ba overlap, the portion of the inner edge at the interface of the shoulder 20b and the base (for ease of description, the inner edge is defined as X)₁) The other part of the inner side edge of the side flap 20b protrudes from the first side edge 201 (the inner side edge is defined as X)₂) The deviation-correcting guide 20e can be installed at any position of the inner side of the side wing 20b as long as it can cooperate with the sliding of the movable plate 20 d. For the embodiment in which both wings 20b are provided with deviation-correcting rails 20e, one of the deviation-correcting rails 20e may be provided at X1, or at X₂Where, of course, both deviation-correcting guide rails 20e are mounted at X₁Or both are mounted at X₂To (3). In order to make the movable plate 20d run more smoothly as a whole, the two deviation-correcting guide rails 20e are staggered in a direction perpendicular to the sliding direction of the movable plate 20d (i.e., one of the deviation-correcting guide rails 20e is installed at the X position)₁Another deviation correcting guide rail 20e is arranged at X₂At (c). With such an arrangement, the two deviation-correcting guide rails 20e provide a mutually oblique supporting force through the wind shielding assembly 30, and in addition, the two movable plates 20d slide more smoothly due to the guiding effect of the two guiding slide rails 20 f. The arrangement of the two deviation-correcting guide rails 20e enables the connecting line of the midpoints of the two deviation-correcting guide rails 20e, the extending direction of the deviation-correcting guide rails 20e and the two movable plates 20d to form a triangle at any time, so that the stability is higher.

To facilitate assembly and securing of the deviation guide 20e, in one embodiment, the inner edges of the side wings 20b are formed with side plates 212, 212' (fig. 7, 12 and 14), and the deviation guide 20e is engaged with the side plates 212. Specifically, the deviation correcting guide rail 20e includes a deviation correcting sliding groove 231a and a deviation correcting protruding rib 232a disposed on the deviation correcting sliding groove 231a, the deviation correcting sliding groove 231a is sleeved on the side plate 212 (the deviation correcting sliding groove 231a can slide up and down along the side plate 212 before being fixed with the side wing 20 b), the movable plate 20d is provided with a guide groove 251a, the guide groove 251a is in sliding fit with the deviation correcting protruding rib 232a, on the same side wing 20b, the notch of the deviation correcting sliding groove 231a faces the guide rail 20f disposed on the side wing 20b, and the deviation correcting protruding rib 232a is disposed on one side of the deviation correcting sliding groove 231a, which faces away from the guide rail 20f of the side wing 20 b. Thus, in the front-rear direction, the guide groove 251a can limit the position of the deviation-correcting rib 232a in a clamping manner.

In addition, to facilitate the detachment and installation of the deviation rectifying chute 231a, the deviation rectifying chute 231a may be detachably fixed to the side wing 20 b. In one embodiment, the side plate 212 is provided with a fixing hole 212a, and the inner wall of the deviation rectifying chute 231a is provided with a clamping platform 236 corresponding to the position of the fixing hole 212 a. Thus, when the deviation correcting rail 20e is installed, the deviation correcting chute 231a can be firmly fixed to the side plate 212 (the deviation correcting chute 231a and the side plate 212 can be kept relatively fixed in the vertical direction) after the clamping table 236 is clamped into the fixing hole 212 a. In order to make the installation of the deviation correcting guide 20e more stable, the wing 20b is provided with a first fixing groove 212b (located at the lower end of the wing 20b and in a notch shape) located inside the side plate 212, the deviation correcting sliding slot 231a has two sides extending along the sliding direction of the side plate 212, wherein one side is provided with a first buckling platform 234 for buckling the side plate 212, and the other side is provided with a second buckling platform 235 matched with the first fixing groove 212 b. In this way, the first fastening platform 234 can fasten one side of the side plate 212, so as to keep one side wall of the deviation rectifying chute 231a fixed relative to the side plate 212, and the second fastening platform 235 can fix the other side wall of the deviation rectifying chute 231a on the side plate 212. Further, referring to fig. 14, the first side 201 of the base 20a is provided with a stopping portion 213, a second fixing groove 213a is formed between the stopping portion 213 and the side plate 212, and the deviation rectifying chute 231a is inserted into the second fixing groove 213 a. To facilitate assembly of the deviation correcting guide rail 20e, a clamping platform 236 and a second buckling platform 235 are disposed at an end of the deviation correcting chute 231a away from the base 20 a.

Further, referring to fig. 15, in order to facilitate the installation and removal of the deviation rectifying chute 231a, the clamping platform 236 is disposed in a triangular shape. That is, when the upper port of the deviation rectifying chute 231a is aligned with the lower end of the side plate 212, the deviation rectifying chute 231a is pushed upwards, the first buckling table 234 is buckled with one side of the side plate 212, when the clamping table 236 abuts against the lower end of the side plate 212, the deviation rectifying chute 231a is continuously pushed upwards with force, at this time, because the clamping table 236 is arranged in a triangular shape, one side of the clamping table 236 is an inclined plane, under the guiding action of the inclined plane, the clamping table 236 gradually goes over the lower end of the side plate 212, and under the abutting action of the clamping table 236 and the side plate 212, the side plate 212 and/or the deviation rectifying guide rail 20e are deformed, until the clamping table 236 is clamped into the fixing hole 212a, the side plate 212 and/or the deviation rectifying guide rail 20e are restored to be deformed, so that the bottom of the deviation rectifying chute 231a can be firmly attached to the side plate 212. In summary, the deviation correcting sliding groove 231a firmly fixes the deviation correcting guide rail 20e on the side plate 212 through four fixing methods (the upper end of the deviation correcting sliding groove 231a is inserted into the second fixing groove 213a, the first fastening table 234 is fastened to the side plate 212, the second fastening table 235 is fastened to the first fixing groove 212b, and the fastening table 236 is fastened into the fixing hole 212 a).

Referring to fig. 14 and 15, the deviation-correcting rib 232a is substantially flush with one side of the deviation-correcting sliding groove 231a, the deviation-correcting rib 232a is clamped into the guiding groove 251a, in order to reduce the friction between the deviation-correcting rib 232a and the inner wall of the guiding groove 251a, a plurality of second cylindrical bodies 233 are disposed on the deviation-correcting rib 232a, that is, the guiding groove 251a has two opposite side walls, at least two arc-shaped protrusions 233a are disposed on two sides of the deviation-correcting rib 232a (the arc-shaped protrusions 233a are the side walls of the second cylindrical bodies 233), and the arc-shaped protrusions 233a disposed on two sides of the deviation-correcting guiding rail 20e are respectively abutted against the two side walls of the guiding groove 251 a.

The two deviation correcting guide rails 20e may be identical in structure or different in structure. In another embodiment, referring to fig. 16 and 17, the deviation rectifying guide rail 20e includes a deviation rectifying chute 231b, the movable plate 20d is provided with a guiding portion 251b, the guiding portion is disposed inside the lateral wing 20b (generally located at the boundary with the base 20a, the base 20a and the lateral wing 20b may not have an obvious boundary line, the two may be integrally formed, or may be assembled), and the guiding portion 251b is slidably disposed in the deviation rectifying chute 231 b.

Referring to fig. 17, in order to further reduce the frictional resistance between the deviation rectifying chute 231b and the guiding portion 251b, the deviation rectifying guide rail 20e further includes a deviation rectifying rib 232b disposed on the inner wall of the deviation rectifying chute 231b, the deviation rectifying rib 232b abuts against the guiding portion 251b, the deviation rectifying rib 231b extends along the vertical direction, the contact area between the deviation rectifying rib 231b and the guiding portion 251b is small, and the sliding is smoother.

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 may be 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, a self-lubricating wear-resistant material may be used as the material of the deviation correcting guide rail 20 e.

When the wind shielding assembly 30 is a cyclone module, the fan blades 301 arranged in the wind shielding assembly 30 can rotate in an active driving mode. In an embodiment, a blade 301 driving assembly is further disposed on one of the movable plates 20d, and the blade 301 driving assembly is connected to the blade 301 and is configured to drive the blade 301 to rotate. The fan blade 301 driving assembly comprises a driving motor 220b and a second gear 221b, and the second gear 221b is in transmission connection with the fan blade 301.

Referring to fig. 11, 12 and 18, the movable plate 20d moves up and down, the driving assembly of the fan blade 301 moves along with the movable plate 20d, and the motor wire 20g connected to the driving motor 220b also moves along, so that the motor wire 20g needs to be redundant for a certain length. The base 20 is provided with a wire passing groove 227 for the wiring of the motor wire 20g, the motor wire 20g penetrates into the wire passing groove 227 through a wire inlet 228 of the wire groove 227 and then is connected with the display box, and the opening of the wire inlet 228 prevents the wire from being approximately 90 degrees with the vertical direction, so that the redundant motor wire 20g is easily bent at a large angle in the moving process after being led out from the wire inlet 228, and the motor wire 20g is easily fatigued for a long time, thereby being damaged. One of them affects the operation of the wind shielding assembly 30, and the other one reduces the service life of the indoor unit of the air conditioner and is easy to cause safety accidents.

In addition, the closer the wire passing groove 227 is to the driving motor 220b, the more easily the motor wire 20g between the two is bent at a large angle, so the wire passing groove 227 should keep a distance with the driving motor 220b in the length direction of the panel 10b, and the longer the distance is, the less easily the motor wire 20g is bent at a large angle.

In an embodiment, referring to fig. 19 to 21, in order to avoid a long motor wire 20g from being bent at a large angle, a first guiding portion 229 is disposed at the wire inlet 228 of the wire passing groove 227, and the first guiding portion 229 may extend obliquely upward from the wire inlet 228 or obliquely downward from the wire inlet 228, and the oblique extension may be along a straight line or along an arc line. If the first guide part 229 extends from the wire inlet 228 in a downward inclination manner, when the movable plate 20d moves downward, the first guide part 229 has a certain bearing capacity on the motor wire 20g, and the bending angle of the motor wire 20g at the end of the first guide part 229 can be reduced. If the first guiding portion 229 extends obliquely upward from the wire inlet 228, when the movable plate 20d moves upward, the motor wire 20g is guided by the first guiding portion 229 after being led out from the wire inlet 228 by the first guiding portion 229, and the motor wire 20g is not bent too much by its own weight.

If the number of the first guide parts 229 is only one, the first guide parts 229 are preferably arranged to extend from the wire inlet 228 in a downward direction.

Considering that the guiding effect of the single first guide part 229 is not as good as that of the two first guide parts 229, in an embodiment, two first guide parts 229 are provided at the wire inlet 228, wherein one first guide part 229 is bent downward from the wire inlet 228, and the other first guide part 229 is bent upward from the wire inlet 228. Thus, no matter the movable plate 20d moves upward or downward, the first guide portion 229 can guide the lengthy motor, thereby preventing the motor wire 20g from bending at a large angle.

In addition, a length s1 of the first guide part 229 extending downward from the wire inlet 228 is defined, and a length s2 of the first guide part 229 extending upward from the wire inlet 228 is defined, and s1 is preferably greater than s 2. This is because the motor wire 20g is under its own action when moving, and the motor wire 20g is more likely to bend at a large angle when contacting the end of the first guide part 229 extending downward, so if the first guide part 229 is lengthened, the tangent line at the end of the first guide part 229 may coincide (or substantially coincide) with the extending direction of the motor wire 20g, so that the extension of the wire 20g after passing through the first guide part 229 is smoother.

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 disposed in a flaring manner in a direction away from the wire inlet 228. On one hand, the two first guiding portions 229 are arranged in an arc shape, and a gap between the two first guiding portions is arranged in a flaring shape, so that the included angle between the tangent lines of the two first guiding portions 229 is increased along with the direction away from the wire inlet 228, and the large-angle bending of the motor wire 20g can be reduced.

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 an embodiment, the movable plate 20d is provided with a second guiding portion 261, the second guiding portion 261 is located at the periphery of the driving motor 220b, the second guiding portion 261 extends downward toward the side where the wire passing groove 227 is located, or the second guiding portion 261 extends upward and obliquely toward the side where the wire passing groove 227 is located.

Of course, the second guide portion 261 is preferably provided in two, similarly to the case of the first guide portion 229. That is, the movable plate 20d is provided with two second guiding portions 261, the two second guiding portions 261 are spaced apart, one of the second guiding portions 261 bends downward, and the other second guiding portion 261 bends upward. The bending effect of the second guide 261 may refer to the first guide 229.

In addition, because motor line 20g is usually with the interface welding of motor, so if the power is dragged to the interface that motor line 20g connects the motor, lead to the interface solder joint to become flexible easily, driving motor 220b contact is bad, and is serious, directly leads to motor line 20g and motor to break away from. In view of this, in one embodiment, the winding portion 262 is disposed between the two second guiding portions 261, and the winding portion 262 is spaced apart from the two second guiding portions 261. After setting up winding portion 262, motor line 20g can be twined and establish on winding portion 262, even if receive and pull the power, motor line 20g can pull the power with most and disperse to winding portion 262 to it is not hard up with the solder joint of motor interface to avoid motor line 20 g.

There are various routing ways of the motor wire 20g between the two second guiding portions 261, for example, a gap between the winding portion 262 and one second guiding portion 261 close to the driving motor 220b is defined as a first gap, a gap between the winding portion 262 and the other second guiding portion 261 is defined as a second gap, and the motor wire 20g is led out from the driving motor 220b, passes through the first gap, then passes through the second gap, and then enters the wire inlet 228 through the gap between the two first guiding portions 229. The motor wire 20g may also be led out from the motor, and then pass through the second gap, then pass through the first gap, and then enter the wire inlet 228 through the gap between the two first guiding portions 229. That is, the motor wire 20g connected to the driving motor 220b is wound around the outer circumference of the winding portion 262 and enters the wire passing groove 227 through a gap between the two first guides 229. With this one-turn winding, 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 completely transferred to the winding portion 262 at a moment, and therefore, the arrangement of the winding portion 262 provides an excellent protection effect for the connection of the motor wire 20 g.

For the embodiment without the winding portion 262, the winding may be performed in such a manner that the motor wire 20g is wound around the outer circumference of the driving motor 220b after being drawn out from the motor, 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 passing groove 227. That is, the outer wall of the driving motor 220b replaces the above-mentioned winding part 262, and after the motor wire 20g is subjected to a sudden pulling force, the pulling force can be instantaneously offset by the friction force generated between the driving motor 220b and the motor wire 20g, so as to protect the connection of the motor wire 20 g.

The movable plate 20d has two extreme positions moving to the top and the bottom, the stroke between the two extreme positions is the maximum stroke of the movable plate 20d, and the length of the redundant motor wire 20g between the wire inlet 228 and the wire winding part 262 must be always larger than the linear distance between the wire inlet 228 and the wire winding part 262, otherwise, the motor wire 20g is subjected to a severe pulling force during the up-and-down movement of the movable plate 20 d. In addition, the redundant motor wire 20g between the wire inlet 228 and the wire winding portion 262 is not too long, because the too long motor wire 20g may be twisted and knotted between the wire inlet 228 and the wire winding portion 262, thereby easily causing premature fatigue damage to the motor wire 20 g. Therefore, the length of the motor wire 20g between the wire inlet 228 and the wire winding portion 262 is preferably slightly greater than the linear distance between the wire inlet 228 and the wire winding portion 262, for example, the linear distance between the wire inlet 228 and the wire winding portion 262 is L1, the length of the motor wire 20g between the wire inlet 228 and the wire winding portion 262 is L2, and 1.1 × L1 ≤ L2 ≤ 1.3 × L2. Of course, since there are two upper and lower extreme positions of the movable plate 20d, in order to satisfy that the length of the motor wire 20g between the wire inlet 228 and the wire winding portion 262 is just slightly greater than the linear distance between the wire inlet 228 and the wire winding portion 262 when the movable plate 20d is in the two upper and lower extreme positions, in this embodiment, the wire inlet 228 may be disposed in the middle of the maximum stroke of the movable plate 20d, that is, the wire inlet 228 is approximately centered on the maximum stroke of the movable plate 20 d.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
