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

An air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1 to 4, the air conditioner 100 may include: the air conditioner comprises an air conditioner body 1, a switch door 2 and a driving assembly 3, wherein the switch door 2 is matched with the air conditioner body 1 in a sliding mode, and the switch door 2 can slide in a lifting mode between a lifting position (shown in figure 2 for example) and a falling position (shown in figure 1 for example) relative to the air conditioner body 1.

The driving assembly 3 comprises supports 30, reels 31, movable pulleys 32 and ropes 33, the supports 30 are arranged on the air conditioner body 1, the supports 30 are two and are respectively arranged on two transverse sides of the switch door 2, the movable pulleys 32 are arranged on the switch door 2 and comprise at least one first movable pulley 321, the first movable pulleys 321 are positioned below the two supports 30, the ropes 33 are wound on the movable pulleys 32 and are wound on the first movable pulleys 321 through the bottoms of the first movable pulleys 321, two ends of the ropes 33 respectively extend and are matched with the two supports 30, at least one end of each rope is connected with the reels 31, the reels 31 wind the ropes 33 to enable the switch door 2 to rise, and the reels 31 release the ropes 33 to enable the switch door 2 to fall.

It should be noted that the relative position of the reel 31 and the holder 30 is not limited, and the fitting relationship between the two ends of the rope 33 and the two holders 30 can be designed in a matching manner after the relative position of the reel 31 and the holder 30 is determined. For example, there are at least the following five embodiments.

Example one

Each support 30 is provided with a reel 31, and the two reels 31 are connected to two ends of a rope 33. Therefore, the structure is simple and compact.

Example two

One end of the rope 33 is fixedly connected to one of the holders 30, and a reel 31 is mounted on the other holder 30 and connected to the other end of the rope 33. Therefore, the cost is low, and the structure is simple and compact.

EXAMPLE III

One end of the rope 33 is fixedly connected to one of the supports 30, the other support 30 is provided with a support pulley, the reel 31 is one and spaced apart from the support 30, and the other end of the rope 33 passes around the support pulley and is connected to the reel 31. Thus, the position of the cord reel 31 can be flexibly designed, for example, the cord reel 31 can be installed on a bracket facing the opening/closing door 2, and the cost can be reduced. In addition, in this embodiment, the cord reel 31 may be provided on the air conditioner body 1 or the opening/closing door 2.

Example four

Each support 30 is provided with a support pulley, the reel 31 is one and is spaced apart from the two supports 30, and two ends of the rope 33 are wound around the support pulleys on two sides respectively and are connected to the same reel 31. Therefore, the position of the winder 31 can be flexibly designed, for example, the winder 31 can be arranged on a bracket right opposite to the switch door 2, and the like, and the design uniformity of the two ends can be improved, the balance is improved, and the cost is reduced. In addition, in this embodiment, the cord reel 31 may be provided on the air conditioner body 1 or the opening/closing door 2.

EXAMPLE five

Each support 30 is provided with two supporting pulleys, the reels 31 are spaced apart from the two supports 30, and two ends of the rope 33 are wound around the supporting pulleys on two sides respectively and connected to the two reels 31 respectively. Therefore, the position of the reel 31 can be flexibly designed, for example, the reel 31 can be arranged on a bracket right opposite to the opening and closing door 2, and the uniformity of design of two ends can be improved, and the balance is improved. In addition, in this embodiment, the cord reel 31 may be provided on the air conditioner body 1 or the opening/closing door 2.

Specifically, the rope 33 sequentially passes around the respective movable pulleys 32 according to the designed path, passes through the bottom of the first movable pulley 321 as it passes around the first movable pulley 321, so that the rope 33 can apply an upward lifting force to the first movable pulley 321, and thus can pass through the first movable pulley 321 as a force receiving point for supporting the opening and closing door 2, and when the rope 33 lifts up the first movable pulley 321, the first movable pulley 321 can pull the opening and closing door 2 to ascend.

Specifically, when the rope 33 is wound by the reel 31, the exposed length of the rope 33 is shortened, the rope 33 can overcome the gravity of the opening and closing door 2 to pull and lift the opening and closing door 2, when the rope 33 is released by the reel 31, the exposed length of the rope 33 is lengthened, the rope 33 is not enough to overcome the gravity of the opening and closing door 2, and the opening and closing door 2 descends under the action of the self gravity. For example, when the cord reel 31 is rotated forward, the cord 33 is wound on the cord reel 31 to shorten the exposed length of the cord 33, and when the cord reel 31 is rotated backward, the cord 33 is unwound from the cord reel 31 to lengthen the exposed length of the cord 33.

For simplicity, only one reel 31 is mounted on each support 30.

For example, when both reels 31 are rotated forward, the exposed length of the rope 33 can be made shorter more quickly; when one reel 31 rotates forward and the other reel 31 does not rotate, the exposed length of the rope 33 can be shortened; when one reel 31 is rotated forward and the other reel 31 is rotated backward, but the rotation speed of the forward rotation is higher than that of the backward rotation, the exposed length of the rope 33 can be shortened. Thus, in these cases, the switching door 2 can be lifted by pulling the switching door 2 by the rope 33.

On the contrary, when both reels 31 are reversed, the exposed length of the rope 33 can be made longer more quickly; when one reel 31 is reversed and the other reel 31 is not rotated, the exposed length of the rope 33 can be increased; when one reel 31 is rotated in the reverse direction and the other reel 31 is rotated in the forward direction, but the rotation speed in the reverse direction is higher than the rotation speed in the forward direction, the exposed length of the rope 33 can be increased. In these cases, the opening/closing door 2 can be lowered by gravity.

Therefore, the supports 30 are respectively arranged at the two ends of the rope 33, when at least one support 30 comprises the reels 31, the switch door 2 can be skillfully driven to slide, when the two supports 30 comprise the reels 31, and the two reels 31 work in the same direction, the sliding speed of the switch door 2 can be increased, the stress of each reel 31 can be reduced, the service life of each reel 31 is prolonged, when one reel 31 fails or is damaged, the other reel 31 works independently, the sliding driving of the opposite-opening door 2 can also be realized, and the working reliability of the whole driving assembly 3 is higher. In addition, the driving assembly 3 has a simple structure and low cost. Moreover, compared with the scheme that the gear rack assembly is adopted to drive the switch door 2 to slide, the driving noise can be reduced, the friction loss between the gear and the rack during driving is avoided, and the mechanical efficiency is higher.

In addition, because two supports 30 are located the horizontal both sides of switch door 2 respectively, two supports 30 distribute in the both sides of switch door 2 along the direction of sliding of perpendicular to switch door 2 promptly to make the atress of switch door 2 more balanced, through setting up the first movable pulley 321 that is less than two supports 30, when at least one winder 31 was worked, rope 33 can promote switch door 2 through pulling first movable pulley 321, and utilize the cooperation of each movable pulley 32 and rope 33, can make rope 33 self-interacting between the support 30 of both sides, further improve the atress equilibrium of switch door 2, further promote the stationarity that switch door 2 goes up and down.

In some specific examples, the two reels 31 wind the rope 33 at the same time, the exposed length of the rope 33 is shortened rapidly, so that the switch door 2 can be pulled to ascend rapidly against gravity, the switch door 2 ascends rapidly to the rising position, the two reels 31 release the rope 33 at the same time, and the exposed length of the rope 33 is lengthened rapidly, so that the switch door 2 can descend rapidly under the action of gravity, and the switch door 2 descends rapidly to the falling position. And, two reels 31 synchronous rotation can make the atress of switch door 2 more balanced, further improves the stationarity that switch door 2 goes up and down.

In addition, two reelers 31 syntropy during operation, even if have some nonconformities in the chronogenesis, can not mutual interference and influence the bulk motion trend of switch door 2, even, two reelers 31 reverse workings, as long as there is the difference in the rotational speed, the elevating movement can also be realized to switch door 2, can not take place because two reelers 31 turn to the nonconformity, and lead to the problem that drive assembly 3 damaged or became invalid, and the problem that switch door 2 can't go up and down, thereby can further improve drive assembly 3's operational reliability and life.

It should be noted that the specific type of the air conditioner 100 is not limited, and may be an air conditioner split unit or an air conditioner integrated unit, the air conditioner split unit may be an indoor cabinet unit or an indoor on-hook unit, and the air conditioner integrated unit may be a window type air conditioner or a mobile air conditioner. After the type of the air conditioner 100 is determined, a person skilled in the art can know the specific structure of the air conditioner body 1, for example, the air conditioner body 1 may generally include a housing, a blower and a heat exchanger disposed in the housing, and when the air conditioner 100 is a cabinet indoor unit, the housing may include a rear cabinet, a front panel 12, a base, a top plate, and the like. For another example, when the air conditioner 100 has other functions besides temperature adjustment, the air conditioner body 1 may further include auxiliary functional components, such as a humidifying component, a fresh air component, a purifying component, and the like, which are not described herein again.

In addition, it should be noted that the function of the opening and closing door 2 is not limited, for example, in some embodiments, the opening and closing door 2 may be used to block an open area of the air conditioner body 1, the open area may be used to receive accessories, for example, the air conditioner body 1 may have a receiving cavity 11, a mobile handset may be in the receiving cavity 11, the opening and closing door 2 is used to open and close the receiving cavity 11, when the receiving cavity 11 is opened by the opening and closing door 2, the mobile handset may be taken out from the receiving cavity 11, and after the mobile handset is taken out from the receiving cavity 11, or when the mobile handset is received back into the receiving cavity 11, the receiving cavity 11 may be closed by using the opening and closing door 2. For example, in some other embodiments, the air conditioner body 1 may have a vent, such as an air outlet and an air inlet, and the switch door 2 may also be used to switch the vent of the air conditioner body 1, so that when the vent is not needed, the switch door 2 may be used to shield and close the vent to prevent dust and the like from entering the vent, and when the vent is needed, the switch door 2 may be used to open the vent to ensure the normal ventilation function of the vent.

Some air conditioners in the related art are provided with a liftable opening and closing door, and the air conditioner drives the opening and closing door to lift by arranging a gear and rack mechanism. However, the cost and the structure of the lifting motion of the opening and closing door realized by the gear rack mechanism are higher. In addition, in the gear and rack driving scheme, the motion friction of the gear and rack is large, the energy loss is large, the mechanical efficiency is low, and the working noise is large. In addition, if the gear and rack driving scheme is single-motor motion, namely one gear drives one rack to move, the stress of the opened and closed door is unbalanced, and the problem of deflection is easy to occur, and if the gear and rack driving scheme is double-motor motion, namely two gears drive one rack to move from two sides of the width together, if the motion between the driving motors of the two gears is inconsistent, the driving of the two gears to the rack can interfere with each other, the normal lifting of the opened and closed door is influenced, and the driving motors of the gears are easy to damage or the service life is shortened.

In the air conditioner 100 according to the embodiment of the present invention, the door 2 is lifted by the rope 33, and the two ends of the rope 33 are connected by two reels 31, or the two ends of the rope 33 are fixed by one reel 31 and one support 30, so that when the reels 31 are operated, the reels 31 can wind the rope 33, the door 2 is lifted, the reels 31 reversely release the rope 33, and the door 2 is lowered by gravity. When the air conditioner 100 is provided with the storage cavity 11, the storage cavity 11 can be opened and closed by the lifting of the switch door 2, so that the requirement of moving the sub machine into and out of the storage cavity 11 can be met.

Therefore, compared with a gear rack mechanism, the driving assembly 3 has almost no mechanical friction during working, little energy loss, more efficient movement and low noise; through the cooperation of rope 33 and each movable pulley 32, the position can be adjusted automatically between the support 30 of both sides to rope 33 to the inconsistent of adaptation rope 33 both ends motion, thereby makes the atress of switch door 2 balanced, promotes the lift stationarity of switch door 2, and can avoid winder 31 to damage or life-span to shorten.

In short, according to the driving assembly 3 of the embodiment of the present invention, the problems of large movement noise, low mechanical efficiency, unbalanced stress when a single motor is used for driving the rack-and-pinion mechanism, and asynchronous movement when two motors are used for driving the rack-and-pinion mechanism can be solved, and compared with rack-and-pinion transmission, the driving assembly 3 of the embodiment of the present invention has the advantages of simpler structure, higher working reliability, and more stable movement for opening and closing the door 2.

In some embodiments, as shown in fig. 4, when the opening and closing door 2 is located at the falling position, two supports 30 are symmetrically provided at both lateral sides of the upper end of the opening and closing door 2. This can increase the distance that the door 2 can be raised as much as possible.

In some embodiments, as shown in fig. 4, the first movable pulley 321 is provided at the lower end of the opening and closing door 2. This can increase the distance that the door 2 can be raised as much as possible.

In some embodiments, as shown in fig. 4 and 5, the first movable pulleys 321 are plural and spaced apart in the lateral direction, the movable pulleys 32 further include second movable pulleys 322, the second movable pulleys 322 are disposed on the switching door 2, and at least one second movable pulley 322 is disposed above each adjacent two first movable pulleys 321. Thus, by providing the plurality of first movable pulleys 321, more stress points can be provided, and the opening/closing door 2 can be driven to ascend and descend more stably and reliably. In addition, by providing the second movable pulleys 322, the direction of the rope 33 can be changed to play a role of tensioning, so that the rope 33 can be wound on the plurality of second movable pulleys 322 more stably, and the reliability and stability of driving are improved.

For example, in one specific example, the movable pulleys 32 may be plural and include two first movable pulleys 321 and one second movable pulley 322, the two first movable pulleys 321 are provided at the lower end of the opening and closing door 2 and are spaced apart in the lateral direction, and the second movable pulley 322 is provided between the two first movable pulleys 321 and is higher than the two first movable pulleys 321. Thus, the rope 33 can be extended from one reel 31, and first go down around a first movable pulley 321 close to it, then go up around a second movable pulley 322, then go down around another first movable pulley 321, then go up around another first movable pulley 321, and then wind around another reel 31.

From this, when rope 33 was shortened by the rolling of winder 31, can rely on and mention two first movable pulleys 321 and promote switch door 2, because two first movable pulleys 321 set up along horizontal interval to make switch door 2's atress more balanced, improve switch door 2's lift stationarity. Moreover, the second movable pulley 322 which is positioned between the two first movable pulleys 321 and is higher than the first movable pulleys 321 is arranged, so that the rope 33 can be wound into the second movable pulley 322 from top to bottom and wound out of the second movable pulley 322 from bottom to top, the matching between the rope 33 and the second movable pulley 322 is more reliable, the problem that the rope 33 is separated from the second movable pulley 322 is solved, and the reliability of the rope 33 for lifting the switch door 2 through the second movable pulley 322 is improved. In addition, since the two first movable pulleys 321 are located at the lower end of the opening and closing door 2, the rising height of the first movable pulleys 321 can be increased as much as possible. In short, the rope 33 of this embodiment has a simple winding manner, requires a small number of movable pulleys 32, has a low cost, and can disperse the stress well, so that the stress of the door 2 is more balanced, and the movement is more reliable and stable.

Alternatively, the extending direction of the rotational axis of the first movable pulley 321 is perpendicular to the extending direction of the rotational axis of the second movable pulley 322. For example, in the example shown in fig. 5, the rotation shaft extending direction of the first movable pulley 321 is the left-right direction, and the rotation shaft extending direction of the second movable pulley 322 is the front-rear direction, so that the rope 33 can be wound substantially axisymmetrically about the second movable pulley 322 at the time of winding, thereby simplifying the winding, and the two reels 31 can be installed symmetrically, reducing the difficulty of design and assembly.

In some embodiments of the present invention, as shown in fig. 5 and 6, the air conditioner 100 includes: first pulley support 4, first pulley support 4 is located switch door 2 just includes first fender portion 41, first movable pulley 321 install in first pulley support 4, just first fender portion 41 shelter from in week side bottom and the axial both sides of first movable pulley 321. Thus, the first movable pulley 321 can be attached by providing the first pulley holder 4, and the first wire blocking portion 41 can be provided to prevent the rope 33 from being disengaged from the first movable pulley 321, thereby improving the operational reliability of the drive unit 3.

For example, in the specific example shown in fig. 5 and 6, the first wire retaining portion 41 may include a first circumferential portion 411 and two first end portions 412, the two first end portions 412 are disposed at two axial sides of the first movable pulley 321, the first circumferential portion 411 is disposed at a circumferential bottom of the first movable pulley 321 and is connected to the two first end portions 412, the first movable pulley 321 is disposed in a first installation cavity defined by the first circumferential portion 411 and the two first end portions 412, a first winding space 42 is defined between the first circumferential portion 411 and a circumferential surface of the first movable pulley 321, and first wire passing openings that are open upward are defined between two circumferential ends of the first circumferential portion 411 and the first movable pulley 321, so that the rope 33 may extend downward into the first winding space 42 through the first wire passing opening at one side, wind around the first wire passing opening at the other side along the first movable pulley 321, and extend upward out of the first winding space 42. Thus, by defining the opening orientation of the first wire passing opening, the rope 33 can be better prevented from being disengaged from the first movable pulley 321, thereby improving the operational reliability of the driving assembly 3.

Furthermore, the invention is not limited thereto, for example, in other embodiments of the invention, the drive assembly 3 may not include the second movable pulley 322. For example, in some other embodiments, the first movable pulleys 321 are multiple and spaced apart in the transverse direction, the driving assembly 3 further includes a fixed pulley, the fixed pulley is disposed on the air conditioner body 1, and at least one fixed pulley is disposed above between every two adjacent first movable pulleys 321 (this embodiment is not shown in the figure). Accordingly, in the process of lifting the opening and closing door 2 with respect to the air-conditioning body 1, the fixed pulley is fixed with respect to the air-conditioning body 1, and thus the length of the rope 33 between the first movable pulley 321 and the fixed pulley is changed, thereby making it possible to further increase the lifting speed of the opening and closing door 2.

The first movable pulley 321 is not limited to a specific configuration, and may be, for example, a roller or a rolling bearing, which facilitates the cable 33 to pass around and slide freely relative to the first movable pulley. Similarly, the second movable pulley 322 is not limited to a specific structure, and may be a roller or a rolling bearing, for example, which facilitates the cable 33 to pass around and slide freely relative to the pulley.

The specific type of the vibration damping pad is not limited, and may be, for example, a rubber pad 314. The specific type of the driving motor 311 is not limited, and may be, for example, a servo motor, and the like, which is not limited herein.

In some embodiments of the present invention, as shown in fig. 2 and 5, sliding assemblies 6 are respectively disposed on two lateral sides of the opening and closing door 2, sliding rail assemblies 7 are respectively disposed on two lateral sides of the opening and closing door 2 of the air conditioner body 1, and the sliding assemblies 6 are in sliding fit with the sliding rail assemblies 7 on the corresponding sides. From this, set up slide rail set spare 7 and the cooperation of subassembly 6 that slides respectively through the horizontal both sides at switch door 2 to can further improve the stability that switch door 2 and air conditioner body 1 slided relatively. In addition, because the subassembly 6 and the sliding rail subassembly 7 that will slide do not set up in the middle part of switch door 2 equipotential position to avoid when switch door 2 is in the open position, sliding rail subassembly 7 still is in the closed position of switch door 2 and forms the problem of local shading.

Optionally, the length direction of switch door 2 is upper and lower direction, and the width direction of switch door 2 is horizontal, and at this moment, air conditioner body 1 sets up slide rail set 7 respectively in the width both sides of switch door 2, and slide assembly 6 slides the cooperation with the slide rail set 7 that corresponds the side. From this, set up slide rail set spare 7 and the cooperation of subassembly 6 that slides respectively through the width both sides at switch door 2, can further improve the stability that switch door 2 and air conditioner body 1 slided relatively.

Further, as shown in fig. 10 to 13, the slide rail assembly 7 on each side includes a first slide rail 71 and a second slide rail 72 which are vertically spaced apart, as shown in fig. 5, the slide assembly 6 on each side includes a first slide piece 61 which is matched with the first slide rail 71 and a second slide piece 62 which is matched with the second slide rail 72, and the lower end of the first slide rail 71 and the lower end of the second slide rail 72 extend obliquely toward a direction away from the switch door 2. It should be noted that the inclined extension may be inclined along a straight line, or may be inclined along a curved line, such as an arc, and the like, which is not limited herein.

Namely, each side of the sliding assembly 6 comprises a first sliding member 61 and a second sliding member 62 which are arranged at intervals along the length direction of the switch door 2, the first sliding member 61 can be matched with a first sliding rail 71 in a sliding way, the second sliding member 62 can be matched with a second sliding rail 72 in a sliding way, the end part of the first sliding rail 71 close to the second sliding rail 72 is provided with an end part of the second sliding rail 72 far away from the first sliding rail 71, and the end part of the second sliding rail 72 extends towards the direction far away from the switch door 2 in an inclined way.

That is, the slide rail assembly 7 on each side is divided into two sections, namely, the first sliding rail 71 and the second sliding rail 72, so that the end portion of the first sliding rail 71 close to the second sliding rail 72 can extend obliquely in the direction close to the second sliding rail 72 toward the direction away from the switch door 2, and the end portion of the second sliding rail 72 far from the first sliding rail 71 can extend obliquely in the direction away from the first sliding rail 71 toward the direction away from the switch door 2.

Therefore, when the switch door 2 moves along the direction from the second sliding rail 72 to the first sliding rail 71, the switch door 2 can move a certain distance in the direction away from the air conditioner body 1 in the general thickness direction of the switch door 2 through the inclined end part of the sliding rail, so that the switch door 2 is prevented from interfering with the appearance surface of the air conditioner body 1, and then normally slides along the straight line section of the sliding rail. Similarly, when the door 2 moves along the direction from the first sliding rail 71 to the second sliding rail 72, the door can firstly normally slide along the straight line section of the sliding rail, and when the door is about to slide in place, the door 2 moves for a certain distance in the direction close to the air conditioner body 1 in the general thickness direction of the door 2 through the inclined end of the sliding rail, so as to reduce the fit clearance between the door 2 and the air conditioner body 1, so that the appearance surface of the door 2 and the appearance surface of the air conditioner body 1 can be coplanar or coplanar as much as possible, and the appearance consistency of the air conditioner 100 is improved.

For example, referring to the specific examples shown in fig. 1-2 and 10-13, the opening and closing door 2 can be lifted and slid between a lifted position and a lowered position relative to the air conditioner body 1, the air conditioner body 1 includes a front panel 12 and a storage cavity 11, the storage cavity 11 is located below the front panel 12, when the opening and closing door 2 is located at the lowered position, the opening and closing door 2 is located below the front panel 12 to shield the storage cavity 11, and when the opening and closing door 2 is lifted to the lifted position, at least a part of the opening and closing door 2 moves to above the storage cavity 11 and is located in front of the front panel 12 to open the storage cavity 11.

The first sliding rail 71 is located on the left and right sides of the front panel 12, and the second sliding rail 72 is located on the left and right sides of the storage chamber 11. That is, the first sliding rails 71 are provided on both the left and right sides of the front panel 12, the second sliding rails 72 are provided on both the left and right sides of the storage chamber 11, the first sliding rail 71 on the left side is located above the second sliding rail 72 on the left side, and the first sliding rail 71 on the right side is located above the second sliding rail 72 on the right side. The first sliding rail 71 and the second sliding rail 72 extend vertically, the lower end of each first sliding rail 71 extends obliquely backward from top to bottom, and the lower end of each second sliding rail 72 also extends obliquely backward from top to bottom.

When the storage cavity 11 needs to be opened, the opening and closing door 2 moves upwards from the falling position to the rising position, under the guiding action of the lower end of the first sliding rail 71 and the lower end of the second sliding rail 72, so that the opening and closing door 2 can tilt forwards and upwards to move to the front side of the plane of the front surface of the front panel 12, and then moves upwards along the first sliding rail 71 and the second sliding rail 72 in a straight line, so that the opening and closing door 2 can move on the front side of the front panel 12 without being interfered by the front panel 12.

When the storage cavity 11 needs to be closed, the switching door 2 descends from the rising position to the falling position, the switching door 2 linearly moves downwards along the first sliding rail 71 and the second sliding rail 72, and when the switching door 2 reaches the falling position, the switching door 2 moves backwards and downwards under the guiding action of the lower end of the first sliding rail 71 and the lower end of the second sliding rail 72, so that the front surface of the switching door 2 is coplanar or approximately coplanar with the front surface of the front panel 12, and the appearance consistency of the air conditioner 100 is improved.

For example, the left and right sides of the upper half and the lower half of the air conditioner body 1 are respectively designed with sliding rails, the sliding rail of the upper part is a first sliding rail 71, the sliding rail of the lower part is a second sliding rail 72, the shapes of the first sliding rail 71 and the second sliding rail 72 are identical, the shapes of the first sliding rails 71 of the left and right sides are symmetrically arranged, the shapes of the second sliding rails 72 of the left and right sides are symmetrically arranged, each sliding rail extends along the vertical direction as a whole, and the lower end part is inclined backwards, so that when the door 2 moves along the first sliding rail 71 and the second sliding rail 72, the door 2 is opened and closed to move upwards and then forwards; the opening and closing door 2 is lowered to slide downward and then to slide backward. Therefore, smooth lifting of the opening and closing door 2 can be guaranteed, and the air conditioner 100 is good in overall appearance consistency when the opening and closing door 2 descends.

It should be noted that, since the opening/closing door 2 moves in the substantial thickness direction of the opening/closing door 2 during the movement, and the rope 33 moves between the movable pulley 32 and the reel 31, the first pulley holder 4 and the second pulley holder 5 can effectively prevent the rope 33 from being separated from the movable pulley 32, thereby improving the operational reliability of the driving unit 3. In addition, it should be noted that the specific material of the rope 33 is not limited, and for example, the rope may be a steel wire rope, so that the rope has a better bearing capacity and a longer service life.

In some embodiments, as shown in fig. 2, the second sliding rail 72 is located on the inner cavity wall of the receiving cavity 11, and at least a portion of the second sliding member 62 extends into the receiving cavity 11 to slidably engage with the second sliding rail 72. Therefore, the second sliding rail 72 can be hidden by the housing chamber 11, the second sliding rail 72 can be protected, and the reliability of the fitting between the second sliding rail 72 and the second slider 62 can be improved. In addition, as shown in fig. 2, the first sliding rails 71 are located at the left and right sides of the front panel 12, so that they can be selectively processed to be exposed to the outside, thereby simplifying the structure and facilitating the processing.

It should be noted that the specific configuration of the first sliding member 61 and the second sliding member 62 is not limited, for example, in the examples shown in fig. 13 and 14, each of the first sliding member 61 and the second sliding member 62 may include: a structural support 63, a roller bearing 64 and a bull eye bearing 65. Be equipped with back shaft 66 on the structure support 63, the blind hole has been seted up in the centre of back shaft 66, roller bearing 64 installs on back shaft 66, bull's eye bearing 65 installs in the blind hole, first sliding rail 71 and second sliding rail 72 all construct the spout form, the spout includes two lateral walls and the diapire of connection between two lateral walls, be formed with spacing recess 73 on the spout diapire, roller bearing 64 locates between two lateral walls and rolls along the lateral wall, bull's eye bearing 65 cooperates and slides in spacing recess 73, thereby when the sliding rail of the left and right sides and sliding member all cooperate and target in place, can realize reliable cooperation and spacing of sliding member and sliding rail, reduce the sliding wear between the two, improve sliding fit's smoothness, and, through setting up bull's eye bearing 65, can avoid the problem of the contact and the wearing and tearing of the axle head face of antifriction bearing and spout diapire.

In some embodiments of the present invention, as shown in fig. 1 and 2, the air conditioner 100 may further include a latch assembly 9, the latch assembly 9 is disposed between the switching door 2 and the air conditioner body 1 and is switchable between a locking state and an unlocking state, when the latch assembly 9 is switched to the locking state, the latch assembly 9 locks the relative positions of the air conditioner body 1 and the switching door 2, and the latch assembly 9 is adapted to be switched to the locking state when the switching door 2 is moved to the rising position and/or the falling position.

That is, the catch assembly 9 may be arranged such that the catch assembly 9 switches to the locked state only when the switching door 2 is in the raised position. It is also possible to arrange the catch assembly 9 such that the catch assembly 9 switches to the locked state only when the switching door 2 is in the lowered position. The catch assembly 9 may also be arranged such that when the switching door 2 is in the raised position, the catch assembly 9 switches to the locked state, and when the switching door 2 is in the lowered position, the catch assembly 9 also switches to the locked state. Therefore, the locking assembly 9 can be used for enabling the switch door 2 to stably stay at the rising position or the falling position.

It should be noted that the capture assembly 9 may be in an automatic capture mode, or may be in a driving capture mode. Wherein, the form of automatic locking means, need not control, when switch door 2 moves to the target location relative to air conditioner body 1, the subassembly 9 that locks can automatic switch over for the state of locking, for example, when switch door 2 moves to the target location relative to air conditioner body 1, the spring bolt 91 in the subassembly 9 that locks is relative with lockhole 92 position, the spring bolt 91 can be at this moment under the effect of elasticity during automatic entering lockhole 92, when switch door 2 moves relative to air conditioner body 1, can overcome elasticity for spring bolt 91 deviates from lockhole 92 and realizes the unblock. In addition, the driving locking form means that control is required, when the switch door 2 moves to a target position relative to the air conditioner body 1, the locking assembly 9 can be controlled to be switched to a locking state, for example, when the switch door 2 moves to the target position relative to the air conditioner body 1, the locking tongue 91 in the locking assembly 9 is opposite to the locking hole 92, at this time, the locking tongue 91 can be controlled to be driven to enter the locking hole 92, and when the switch door 2 needs to move relative to the air conditioner body 1, the locking tongue 91 is controlled to be driven to move out of the locking hole 92 again, so that unlocking is achieved.

Further, when the locking assembly 9 is in the driving locking form, the air conditioner 100 may further include a detecting assembly 8 and a control assembly, the detecting assembly 8 may be used to detect the position of the door 2, and the control assembly is electrically connected to the locking assembly 9, the detecting assembly 8 and the cord reel 31 respectively and is used to control the locking assembly 9 and the cord reel 31. Therefore, the electronic control design can realize that when the detection component 8 detects that the switch door 2 reaches the rising position, the control component controls the locking component 9 to be switched to the locking state, and/or when the detection component 8 detects that the switch door 2 reaches the falling position, the control component controls the locking component 9 to be switched to the locking state. And, can realize through automatically controlled design, when needing lift switch door 2, the control assembly controls the locking subassembly 9 earlier and switches into the unblock state, and then controls the work of winder 31.

For example, in some alternative examples, the detection assembly 8 may include a magnet 81, an upper hall switch 82, and a lower hall switch 83. The upper hall switch 82 and the lower hall switch 83 are both mounted on the air conditioner body 1, and are respectively located at the upper end and the lower end of the storage chamber 11. The magnet 81 is installed on the switching door 2 and located at the lower end of the switching door 2. The locking assembly 9 may include a driver, a locking tongue 91 and a locking hole 92, the driver may include a push rod servo motor or a rack and pinion mechanism, etc., the locking tongue 91 is disposed on the air conditioner 100 and located at the upper end of the accommodating cavity 11, the locking hole 92 is disposed on the switch door 2, and the upper end and the lower end of the switch door 2 are respectively provided with the locking hole 92.

Whether the switch door 2 moves at the target position is judged by the distance between the magnet 81 and the Hall switch. When the distance between the magnet 81 and a hall switch is less than or equal to a set value, that is, the switch door 2 moves to a target position, the winder 31 stops operating, the driver drives the lock tongue 91 to pop out into the lock hole 92, and the switch door 2 is locked. When the actuating signal is received, the driver drives the latch tongue 91 to retract and move out of the latch hole 92, the switch door 2 is unlocked, the reel 31 is rotated reversely, and the switch door 2 can move in the other direction. When the distance between the magnet 81 and the other hall switch is less than or equal to the set value, that is, the switch door 2 moves to the other target position, the winder 31 stops running, the driver drives the latch tongue 91 to pop out into the lock hole 92, and the switch door 2 is locked again.
