Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a clothes dryer. Background Art

[0002] The clothes dryer includes a main body, a drying rack and a wire reel installed in the main body. The drying rack is suspended below the main body by a towing rope. The wire reel drives the drying rack to move up and down by winding and releasing the towing rope. The wire reel includes a wire winding shaft for winding the towing rope. The fewer the number of turns of the towing rope wound around the wire winding shaft, the greater the length of the towing rope released by the wire reel, and vice versa. The greater the total length of the towing rope, the greater the maximum amplitude of the up and down movement of the drying rack. The problem with the existing wire reel is that both the axial length and the radius of the wire winding shaft are limited, which restricts the maximum length of the towing rope that the wire winding shaft can wind and release. If the total length of the towing rope is to be increased, it is necessary to increase the axial length or the radius of the wire winding shaft, which will significantly increase the overall size of the wire reel. Therefore, it is necessary to increase the volume of the main body, otherwise the wire reel will occupy more installation space in the main body, and it will be easy to interfere with other functional devices installed in the main body. Summary of the Utility Model

[0003] In view of this, the utility model provides a clothes dryer, which is equipped with a more compact towing rope winding and unwinding mechanism with a smaller envelope size and without reducing the maximum lifting amplitude of the drying rack.

[0004] The clothes dryer provided by the utility model includes a main body, a drying rack and a towing rope winding and unwinding mechanism. The towing rope winding and unwinding mechanism includes:

[0005] A bracket, provided on one of the main body or the drying rack;

[0006] A wire reel, including a first wire shaft and a second wire shaft that are rotatably installed on the bracket and arranged side by side. A first half-side is formed on the half circumference side of the first wire shaft facing away from the second wire shaft, and a second half-side is formed on the half circumference side of the second wire shaft facing away from the first wire shaft;

[0007] A towing rope, including a fixed end and a connecting end. The fixed end is connected to the first wire shaft or the second wire shaft, and the connecting end is connected to the other of the main body or the drying rack. The towing rope is repeatedly and alternately wound around the first half-side and the second half-side;

[0008] A driver, including a transmission member connecting the first wire shaft and the second wire shaft and a driving member connecting the transmission member. The driver is used to drive the first wire shaft and the second wire shaft to rotate in the same rotation direction and accompany each other to wind and release the towing rope.

[0009] Compared with the prior art, the clothes dryer of the present utility model uses two spools to wind and release the traction rope. Without reducing the total length of the traction rope that the reel can wind and release, it not only ensures that the maximum lifting range of the drying rack will not be reduced, but also the axial length and radius of a single spool can be reduced, so that the overall size of the reel is reduced, and then the overall size of the traction rope winding and unwinding mechanism is reduced. The space occupied by the traction rope winding and unwinding mechanism in the main body is also reduced accordingly, which is more convenient for the layout and installation of other functional components in the main body and will not cause the internal volume of the main body to have to increase.

[0010] In one embodiment, a first spiral groove is provided on the circumferential side of the first spool, and a second spiral groove is provided on the circumferential side of the second spool. The spiral directions of the first spiral groove and the second spiral groove are the same.

[0011] With such a setting, when the first spool and the second spool rotate together to wind the traction rope, the number of turns of the traction rope wound on the first half side and the second half side increases together. When the first spool and the second spool rotate together to release the traction rope, the number of turns of the traction rope wound on the first half side and the second half side decreases together. Thus, the orderly winding and orderly release of the traction rope can be realized.

[0012] In one embodiment, both the first spiral groove and the second spiral groove are cylindrical spiral grooves.

[0013] With such a setting, when the first spool and the second spool rotate at a constant speed respectively, the reel can wind and release the traction rope at a constant speed, thereby driving the drying rack to lift and lower at a constant speed.

[0014] In one embodiment, both the first spiral groove and the second spiral groove are conical spiral grooves. The radii of the first spool and the second spool increase in the same direction, and the fixed end is connected to the conical bottom end of the first spiral groove or the second spiral groove.

[0015] With such a setting, the reel can wind and release the traction rope at a gradually changing rate, thereby driving the drying rack to lift and lower at a gradually changing rate. The reel winds the traction rope at a gradually decreasing rate, so that the speed of the drying rack gradually decreases during the rising process, thereby reducing the impact of the drying rack on the main body.

[0016] In one embodiment, the transmission member includes a first wheel body, a second wheel body and a transfer part. The first wheel body is coaxially and fixedly connected to the first spool, the second wheel body is coaxially and fixedly connected to the second spool, the driving member is connected to the transfer part, and the first wheel body and the second wheel body are engaged with the transfer part.

[0017] With such a setting, the driver can accurately drive the first wheel body and the second wheel body to rotate together through the transfer part, thereby accurately driving the first wire shaft and the second wire shaft to rotate together. Thus, the winding speed and release speed of the traction rope can be precisely controlled to achieve precise control of the lifting speed of the drying rack.

[0018] In one of the embodiments, the transfer part includes a transfer gear that meshes the first wheel body and the second wheel body; alternatively, the transfer part includes a transfer worm that meshes the first wheel body and the second wheel body.

[0019] With such a setting, the transmission efficiency of the transmission part in driving the first wire shaft and the second wire shaft to rotate is higher, and the first wire shaft and the second wire shaft can respond sensitively and quickly to the power output of the driving part.

[0020] In one of the embodiments, the transmission part includes a first wheel body, a second wheel body and a flexible transmission part. The first wheel body is fixedly connected to the first wire shaft coaxially, the second wheel body is fixedly connected to the second wire shaft coaxially, the driving part is connected to the flexible transmission part, and the flexible transmission part is sleeved on the first wheel body and the second wheel body.

[0021] With such a setting, the layout of the transmission part is simpler, and the combination configuration of the first wheel body, the second wheel body and the flexible transmission part is easier, which is convenient for quickly completing the assembly of the traction rope winding and unwinding mechanism.

[0022] In one of the embodiments, the flexible transmission part includes a transmission belt sleeved on the first wheel body and the second wheel body; alternatively, the flexible transmission part includes a transmission rope sleeved on the first wheel body and the second wheel body.

[0023] In one of the embodiments, the first wire shaft and the second wire shaft are arranged at intervals on their side parts to form a wire storage interval.

[0024] With such a setting, the maximum capacity of the wire winder for storing the traction rope increases, and the total length of the traction rope that the wire winder can wind and release is longer.

[0025] In one of the embodiments, the traction rope winding and unwinding mechanism further includes a first wire pressing part arranged in the wire storage interval, a second wire pressing part arranged on the periphery of the wire winder. There is a straight wire pressing gap between the first wire pressing part and the second wire pressing part, a first arc-shaped wire pressing gap between the first half side and the second wire pressing part, and a second arc-shaped wire pressing gap between the second half side and the second wire pressing part.

[0026] With such a setting, the first wire pressing part and the second wire pressing part shape-constrain the wire segment of the traction rope located in the wire storage interval through the straight wire pressing gap, the first half side and the second wire pressing part shape-constrain the wire segment of the traction rope wound around the first half side through the first arc-shaped wire pressing gap, and the second half side and the second wire pressing part shape-constrain the wire segment of the traction rope wound around the second half side through the second arc-shaped wire pressing gap. Thus, the tension of the wire segment of the traction rope wound around the reel can be increased, the shape of the wire segment of the traction rope wound around the reel can be maintained, and local stacking, scattering or mutual interference and entanglement of the wire segment of the traction rope wound around the reel can be prevented.

[0027] In one embodiment, the transmission member includes a first crank, a second crank and a connecting rod. The first crank is rotatably arranged on the bracket around the axis of the first wire shaft and is connected to the first wire shaft. The second crank is rotatably arranged on the bracket around the axis of the second wire shaft and is connected to the second wire shaft. The connecting rod is rotatably connected to the first crank and the second crank, and the driving member is connected to the first crank or the second crank.

[0028] With such a setting, the transmission efficiency of the transmission member driving the first wire shaft and the second wire shaft is higher, and both the first wire shaft and the second wire shaft can quickly and sensitively respond to the power output of the driving member.

Detailed implementation manners

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0039] The clothes dryer provided by the present utility model includes a main body, a drying rack and a traction rope winding mechanism 100. The main body is integrated with functional devices such as a blowing device, a heating device, and a disinfection device. The drying rack is used for hanging clothes to be dried. The main body is generally installed on an indoor ceiling or an indoor ceiling board. The drying rack is movably arranged on one side of the main body close to the ground in a liftable manner, and the lifting of the drying rack is realized by controlling the traction rope winding mechanism 100.

[0040] Specifically, the traction rope winding and unwinding mechanism 100 includes a bracket, a wire reel, a traction rope 30, and a driver 40. The bracket is provided on one of the main body or the drying rack. The wire reel is rotatably mounted on the bracket. The traction rope 30 includes a fixed end 31 and a connection end. The fixed end 31 is connected to the wire reel, and the connection end extends from the periphery of the wire reel and is connected to the other of the main body or the drying rack. The rope segment between the fixed end 31 and the connection end can be divided into two parts. One part is the wound rope segment wound around the wire reel, and the other part is the straight and taut rope segment 32 that extends outside the wire reel and is straightened and tensioned. The driver 40 is drivingly connected to the wire reel and is used to drive the wire reel to rotate relative to the bracket to wind and release the traction rope 30. When the wire reel winds up the traction rope 30, the total length of the wound rope segment increases, and the length of the straight and taut rope segment 32 decreases. When the wire reel releases the traction rope 30, the total length of the wound rope segment decreases, and the length of the straight and taut rope segment 32 increases.

[0041] Refer to Figures 1 to 2 , the wire reel includes a first spool 10 and a second spool 20 arranged side by side. The first spool 10 and the second spool 20 are both rotatably mounted on the bracket. The circumferential side of the first spool 10 is divided into two parts, namely the half circumferential side facing away from the second spool 20 and the half circumferential side facing the second spool 20. The circumferential side of the second spool 20 is divided into two parts, namely the half circumferential side facing away from the first spool 10 and the half circumferential side facing the first spool 10. The half circumferential side of the first spool 10 facing away from the second spool 20 forms a first half side 12, and the half circumferential side of the second spool 20 facing away from the first spool 10 forms a second half side 22. It should be noted that the first half side 12 is not a fixed area on the circumferential side of the first spool 10, but changes periodically as the first spool 10 rotates. The second half side 22 is not a fixed area on the circumferential side of the second spool 20 either, and also changes periodically as the second spool 20 rotates.

[0042] Refer to again Figures 1 to 2 , and refer to simultaneously Figures 3 to 4 , as described above, a part of the rope segment of the traction rope 30 between the fixed end 31 and the connection end is the wound rope segment wound around the periphery of the wire reel. The fixed end 31 is specifically connected to either the first spool 10 or the second spool 20. The periphery of the wire reel includes the first half side 12 and the second half side 22, and the wound rope segment alternately winds around the first half side 12 and the second half side 22. As Figure 2 and Figure 4 shown, the fixed end 31 is connected to the first spool 10. Then the traction rope 30 first bypasses the first half side 12 and the second half side 22, and then the traction rope 30 bypasses the first half side 12 for the second time, then bypasses the second half side 22, and then bypasses the first half side 12 again, and so on. The wound rope segment is thus divided into an arc-shaped wound segment 33 wound around the first half side 12 and the second half side 22, and a straight wound segment 34 located between the first half side 12 and the second half side 22.

[0043] It can be understood that when the distance between the first spool 10 and the second spool 20 increases and the distance between the axes of the first spool 10 and the second spool 20 expands, the length of the single straightened winding section 34 will increase. Thus, the total length of the towing rope 30 that the winch can wind and release can be increased, that is, the maximum capacity of the towing rope 30 that the winch can accommodate increases, and the maximum rising amplitude and the maximum falling amplitude of the drying rack during the up and down movement also increase accordingly. Preferably, the sides of the first spool 10 and the second spool 20 are spaced apart to form a rope storage interval, that is, the semi - circumferential side of the first spool 10 facing the second spool 20 and the semi - circumferential side of the second spool 20 facing the first spool 10 are spaced apart to form the above - mentioned rope storage interval.

[0044] Furthermore, the driver 40 includes a transmission member 41 and a driving member. The transmission member 41 connects the first spool 10 and the second spool 20, and the driving member is connected to the transmission member 41. The power generated after the driving member operates is first input to the transmission member 41. The transmission member 41 distributes the received power to the first spool 10 and the second spool 20, and drives the first spool 10 and the second spool 20 to rotate in the same rotation direction to wind and release the towing rope 30. From the observation perspective of the end of the first spool 10 and the end of the second spool 20, the first spool 10 and the second spool 20 rotate synchronously clockwise to wind the towing rope 30, or rotate synchronously counterclockwise to release the towing rope 30 under the drive of the transmission member 41. Moreover, the starting time and the stopping time of the rotation of the first spool 10 and the second spool 20 are the same, and the number of the arc - shaped winding sections 33 wound around the first half - side 12 and the number of the arc - shaped winding sections 33 wound around the second half - side 22 increase or decrease synchronously.

[0045] Optionally, in some embodiments, the bracket is provided on the main body, and the connecting end is connected to the drying rack. The bracket and the main body can be integrally formed and fixedly connected, or can be integrally connected to the main body.

[0046] Refer to Figures 1 to 4, in some embodiments, a first helical groove 11 is formed on the circumferential side of the first spool 10, and the first helical groove 11 is used to accommodate the arc-shaped winding segments 33 wound around the first half 12. A second helical groove 21 is formed on the circumferential side of the second spool 20, and the second helical groove 21 is used to accommodate the arc-shaped winding segments 33 wound around the second half 22, so that the multiple arc-shaped winding segments 33 wound around the first half 12 are arranged along the axial direction of the first spool 10, and the multiple arc-shaped winding segments 33 wound around the second half 22 are arranged along the axial direction of the second spool 20. The helical directions of the first helical groove 11 and the second helical groove 21 are the same. In some embodiments, when the first spool 10 and the second spool 20 are arranged side by side, both the first helical groove 11 and the second helical groove 21 are left-handed thread grooves; in other embodiments, when the first spool 10 and the second spool 20 are arranged side by side, both the first helical groove 11 and the second helical groove 21 are right-handed thread grooves.

[0047] Optionally, in some embodiments, both the first spool 10 and the second spool 20 are cylindrical structures, both the first helical groove 11 and the second helical groove 21 are cylindrical helical grooves, and the fixed end 31 is connected to one end of the first helical groove 11 or connected to one end of the second helical groove 21. When the driver 40 drives the first spool 10 and the second spool 20 to rotate at a constant speed, the first spool 10 winds and releases the traction rope 30 at a constant speed, and the second spool 20 winds and releases the traction rope 30 at a constant speed, so that the lengths of the wound rope segments and the straight rope segments 32 increase or decrease at a constant speed, thereby achieving the purpose of controlling the drying rack to rise or fall at a constant speed.

[0048] Optionally, in other embodiments, the circumferential sides of the first spool 10 and the second spool 20 respectively have a taper, the circumferential radii of the first spool 10 and the second spool 20 increase in the same direction, both the first helical groove 11 and the second helical groove 21 are conical helical grooves, and the fixed end 31 is connected to the tapered bottom end of the first helical groove 11 or connected to the tapered bottom end of the second helical groove 21. Whether it is the first spool 10 or the second spool 20, it includes a small-diameter end face with a smaller radius and a large-diameter end face with a larger radius, and the tapered bottom end of the conical helical groove refers to the end of the helical groove relatively close to the large-diameter end face.

[0049] With such a setting, as the first spool 10 and the second spool 20 wind the traction rope 30, the arc-shaped winding segments 33 wound around the first half 12 are supplemented to the small-diameter end face of the first spool 10, and the arc-shaped winding segments 33 wound around the second half 22 are supplemented to the small-diameter end face of the second spool 20. Correspondingly, the straight rope segments 32 are gradually shortened, and the shortening rate gradually decreases. Thus, the winding device can wind the traction rope 30 at a gradually decreasing rate, and the drying rack approaches the host at a gradually decreasing rate under the drive of the traction rope 30, so as to reduce the impact of the drying rack on the host.

[0050] In some embodiments, the transmission member 41 includes a first wheel body 411, a second wheel body 412 and a transfer portion 413. The first wheel body 411 is coaxially and fixedly connected to the first wire shaft 10, the second wheel body 412 is coaxially and fixedly connected to the second wire shaft 20, the driving member is drivingly connected to the transfer portion 413, and the first wheel body 411 and the second wheel body 412 are respectively meshingly connected to the transfer portion 413. Refer to Figures 1 to 4 , optionally, both the first wheel body 411 and the second wheel body 412 are gears, and they have the same tooth profile modulus. The transfer portion 413 includes a transfer gear 4131 that meshes with the first wheel body 411 and the second wheel body 412. The transfer gear 4131 is located between the first wheel body 411 and the second wheel body 412, and the driving member can be a driving motor connected to the transfer gear 4131.

[0051] In some other embodiments, the transfer portion 413 may further include a toothed ring that meshes with the first wheel body 411 and the second wheel body 412, or may further include a rack that meshes with the first wheel body 411 and the second wheel body 412; in addition, the first wheel body 411 and the second wheel body 412 may also be worm wheels with the same tooth profile parameters. Correspondingly, the transfer portion 413 includes a transfer worm that meshes with the first wheel body 411 and the second wheel body 412. The first wheel body 411 and the second wheel body 412 are located on the same side of the transfer worm, and the driving member can be a driving motor connected to the transfer worm.

[0052] In some embodiments, the transmission member 41 includes a first wheel body 411, a second wheel body 412 and a flexible transmission member 414. The first wheel body 411 is coaxially and fixedly connected to the first wire shaft 10, the second wheel body 412 is coaxially and fixedly connected to the second wire shaft 20, the driving member is drivingly connected to the flexible transmission member 414, and the flexible transmission member 414 is sleeved on the first wheel body 411 and the second wheel body 412. Specifically, refer to Figure 6 , in some embodiments, the flexible transmission member 414 includes a transmission belt sleeved on the first wheel body 411 and the second wheel body 412, and the first wheel body 411 and the second wheel body 412 are two pulley wheels adapted to the transmission belt. In some other embodiments, the flexible transmission member 414 includes a transmission rope sleeved on the first wheel body 411 and the second wheel body 412, and the first wheel body 411 and the second wheel body 412 are two sheave wheels adapted to the transmission rope. The driving member can either contact the flexible transmission member 414 and drive the flexible transmission member 414 through friction, or directly connect to the first wheel body 411 or the second wheel body 412 to drive the flexible transmission member 414.

[0053] Refer to Figure 7, in some embodiments, the transmission member 41 includes a first crank 415, a second crank 416 and a connecting rod 417. The first crank 415 includes a first hinge portion 4151 and a second hinge portion 4152. The second crank 416 includes a third hinge portion 4161 and a fourth hinge portion 4162. The first hinge portion 4151 is hinged to the bracket so that the first crank 415 can rotate around the axis of the first spool 10. The third hinge portion 4161 is hinged to the bracket so that the second crank 416 can rotate around the axis of the second spool 20. The two ends of the connecting rod 417 are respectively rotatably connected to the second hinge portion 4152 and the fourth hinge portion 4162. The second hinge portion 4152 is also connected to the first spool 10, and the fourth hinge portion 4162 is also connected to the second spool 20. The first crank 415 and the second crank 416 have the same length, and together with the connecting rod 417 and the bracket, they form a double-crank mechanism. The driving member is connected to any one of the first crank 415 and the second crank 416. After the driving member starts to operate, the first crank 415 and the second crank 416 rotate in the same rotation direction, thereby respectively driving the first spool 10 and the second spool 20 to rotate in the same rotation direction.

[0054] Refer to Figure 1 , Figure 3 , Figure 5 , in some embodiments, the traction rope winding and unwinding mechanism 100 further includes a first wire pressing portion 51 provided in the wire storage interval and a second wire pressing portion 52 provided on the periphery of the reel. A straight wire pressing gap 53 for the straightened winding section 34 to pass through is provided between the first wire pressing portion 51 and the second wire pressing portion 52. A first arc-shaped wire pressing gap 54 is provided between the first half side 12 and the second wire pressing portion 52, and the first arc-shaped wire pressing gap 54 allows the arc-shaped winding section 33 wound around the first half side 12 to pass through. A second arc-shaped wire pressing gap 55 is provided between the second half side 22 and the second wire pressing portion 52, and the second arc-shaped wire pressing gap 55 allows the arc-shaped winding section 33 wound around the second half side 22 to pass through. When the reel winds up the traction rope 30, the straightened winding section 34 passing through the straight wire pressing gap 53 is in sliding contact with the first wire pressing portion 51 and the second wire pressing portion 52, the arc-shaped winding section 33 passing through the first arc-shaped wire pressing gap 54 is in sliding contact with the surface of the second wire pressing portion 52 close to the first half side 12, and the arc-shaped winding section 33 passing through the second arc-shaped wire pressing gap 55 is in sliding contact with the surface of the second wire pressing portion 52 close to the second half side 22.

[0055] Optionally, as Figure 5As shown, the second wire pressing part 52 is internally hollow and sleeved around the periphery of the wire winder. The first spool 10, the second spool 20, and the first wire pressing part 51 are all located within the second wire pressing part 52. The second wire pressing part 52 is provided with a wire outlet notch for the straightened rope segment 32 to extend outward from the second wire pressing part 52. One side of the first wire pressing part 51 close to the second wire pressing part 52 is a plane and is used to form the surface of the straight wire pressing gap 53. One side of the second wire pressing part 52 close to the first half side 12 is a first inner cylindrical surface, which is coaxially arranged with the first spool 10 and is used to form the surface of the first arc wire pressing gap 54. One side of the second wire pressing part 52 close to the second half side 22 is a second inner cylindrical surface, which is coaxially arranged with the second spool 20 and is used to form the surface of the second arc wire pressing gap 55.

[0056] With such a setting, it can be ensured that the wire winder winds the towing rope 30 more orderly and smoothly. The straight wire pressing gap 53 constrains the shape of the passing straightened winding segment 34 to keep the straightened winding segment 34 in a straight state, and the two arc wire pressing gaps constrain the shape of the passing arc winding segments 33 to keep the arc winding segments 33 in an arc state. During the process of winding the towing rope 30, it can prevent multiple arc winding segments 33 from stacking and concentrating in the spiral wire groove of one of the spools to eliminate the interference and entanglement of the winding rope segments, and can also prevent the arc winding segment 33 from skipping into the spiral wire groove of one of the spools to eliminate the scattering of the winding rope segments on the wire winder.

[0057] Combined Figures 1 to 2 , a brief introduction is made to the operating process of the towing rope winding and unwinding mechanism 100 in the clothes dryer of the present utility model and the principle of winding and releasing the towing rope 30:

[0058] Figure 1 Fig. shows the towing rope winding and unwinding mechanism 100 when the wire winder has just started winding the towing rope 30 for a short time. Figure 2 Fig. shows the towing rope winding and unwinding mechanism 100 after the wire winder has wound the towing rope 30 for a period of time. The axes of the first spool 10 and the second spool 20 are parallel to each other. Compared with Figure 1 compared with Figure 2 in the towing rope winding and unwinding mechanism 100 shown in Fig., the length of the straightened rope segment 32 decreases and the total length of the winding rope segments increases. The first spool 10 and the second spool 20 rotate clockwise from the perspective shown in Figure 1 Fig., and the straightened rope segment 32 in Figure 1Under the perspective shown, it is vertically conveyed downward. The number of turns of the arc winding section 33 wound around the first half side 12 increases and is supplemented in the direction away from the first wheel body 411 along the axis of the first spool 10. The number of turns of the arc winding section 33 wound around the second half side 22 increases synchronously and is supplemented in the direction away from the second wheel body 412 along the axis of the second spool 20. The number of straight winding sections 34 located between the first spool 10 and the second spool 20 also increases synchronously and is supplemented in the direction away from the transmission member 41 along the axes of the first axis and the second axis.

[0059] The beneficial effects of the present utility model are as follows:

[0060] The traction rope winding and unwinding mechanism 100 uses two side-by-side arranged spools that can rotate to wind and unwind the traction rope 30. Without reducing the total length of the traction rope 30 that the winder can wind and unwind, it not only ensures that the maximum ascending range and the maximum descending range of the clothes drying rack do not decrease, but also the axial dimension and the radius dimension of a single spool can be reduced, thereby reducing the overall dimension of the winder. As Figure 2 shown, the winder around which the traction rope 30 is wound is generally flat. Without considering the length of the straight rope section 32 and the total length of the wound rope sections being equal, the axial dimension of the winder of the present utility model (i.e., the dimension of the winder in the axial directions of the first spool 10 and the second spool 20) is shorter than that of the existing winder. When the first spool 10 and the second spool 20 are vertically arranged in the main machine, the dimension of the clothes drying machine main machine of the present utility model in the vertical direction is smaller, the structure of the main machine is flatter, and the flat winder can also leave more available space in the main machine, facilitating the arrangement and installation of other functional devices in the main machine and not causing an increase in the size of the main machine.
