[0002] The traction rope winding and unwinding device is an important part of the main unit of the clothes dryer. Usually, the main unit of the clothes dryer is installed on the indoor ceiling, and the external shape structure of the main unit is largely related to the size and structure of the traction rope winding and unwinding device. With the continuous popularization of the clothes dryer, more and more users hope that the main unit of the clothes dryer has a thin and light external shape structure, so as to obtain a more beautiful experience when viewing the interior of the room.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] 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.

[0025] Refer to Figure 1 , the present utility model provides a traction rope winding and unwinding device 100. The traction rope winding and unwinding device 100 can be one of the components of the main unit of a clothes dryer. When the traction rope winding and unwinding device 100 is used in the main unit of a clothes dryer, the traction rope winding and unwinding device 100 can wind and unwind the traction rope to change the length of the traction rope extending from the main unit to the ground, thereby changing the height of the clothes drying rack connected to the traction rope.

[0026] Furthermore, the present utility model also provides a clothes dryer. The clothes dryer includes the traction rope winding and unwinding device 100 of the present utility model, and also includes a traction rope and a clothes drying rack.

[0027] The traction rope winding and unwinding device 100 includes a housing assembly 10, a wire winding assembly 20, a control assembly 30 and a limiting assembly 40. The housing assembly 10 includes a first mounting portion 112 and a second mounting portion 113. The wire winding assembly 20 includes a wire winding wheel 21 and a driver 22. The wire winding wheel 21 is rotatably arranged on the housing assembly 10 and connected to the driver 22. The control assembly 30 is arranged on the first mounting portion 112 and connected to the driver 22. The limiting assembly 40 is arranged on the second mounting portion 113 and includes a stroke correlation portion 41 and a triggering portion 42. The stroke correlation portion 41 is connected to the wire winding wheel 21, and the triggering portion 42 is connected to the stroke correlation portion 41.

[0028] The wire winding wheel 21 includes a wire winding portion. A wire winding groove extending along a spiral line is formed on the outer peripheral wall of the wire winding portion. The traction rope includes a winding section and an extending section. The winding section refers to the part wound in the wire winding groove, and the extending section refers to the part that has not been wound in the wire winding groove and extends from the main unit of the clothes drying machine to connect to the clothes drying rack. The driver 22 is used to generate a torque for the wire winding wheel 21 to rotate relative to the housing assembly 10. As the wire winding wheel 21 is driven by the driver 22 to rotate, the wire winding portion rotates and winds and unwinds the traction rope through the wire winding groove. The switching process of winding and unwinding the traction rope by the wire winding portion is completed by the driver 22 switching the torque direction.

[0029] The traction rope winding and unwinding device 100 of the present utility model can not only wind and unwind the traction rope, so that the clothes drying rack moves up and down to change the height position of the clothes drying rack, but also can automatically stop winding and / or unwinding the traction rope when the clothes drying rack reaches a specific height position, so that the clothes drying rack can stay at this height position.

[0030] Specifically, the stroke correlation portion 41 is movably arranged relative to the housing assembly 10. The stroke correlation portion 41 maintains a following connection with the wire winding wheel 21, that is, there is a preset conversion ratio relationship between the angular stroke that the wire winding wheel 21 rotates through and the movement stroke of the stroke correlation portion 41 relative to the housing assembly 10. When the wire winding wheel 21 rotates, it drives the stroke correlation portion 41 to move relative to the housing assembly 10. In the case where the conversion ratio relationship is determined, according to one of the angular stroke of the wire winding wheel 21 rotation and the movement stroke of the stroke correlation portion 41 relative to the housing assembly 10, the other can be obtained.

[0031] Further, the trigger part 42 maintains a following connection with the stroke associated part 41, that is, the trigger part 42 follows the movement of the stroke associated part 41 relative to the housing assembly 10 and moves synchronously. When the trigger part 42 follows the movement of the stroke associated part 41 until the trigger part 42 acts on the control assembly 30, the control assembly 30 generates a control instruction, and the drive 22 stops operating under the action of the control instruction, and the wire reel 21 then stops rotating, thus stopping winding or releasing the traction rope. The trigger part 42 can act on the control assembly 30 when the drying rack rises to a preset maximum height, so that the wire winding assembly 20 stops winding the traction rope in response to the control instruction. The trigger part 42 can also act on the control assembly 30 when the drying rack descends to a preset minimum height, so that the wire winding assembly 20 stops releasing the traction rope in response to the control instruction.

[0032] The existing traction rope winding and unwinding device 100 adopts the following design: the housing assembly 10 carries and houses the wire winding assembly 20, and the control assembly 30 and the limiting assembly 40 are installed outside the housing assembly 10. That is to say, the control assembly 30 and the limiting assembly 40 additionally occupy space outside the housing assembly 10, which results in a relatively complex external structure of the traction rope winding and unwinding device 100. The overall envelope size of the traction rope winding and unwinding device 100 is larger than the envelope size of the housing assembly 10. The part larger than the envelope size of the housing assembly 10 includes the space occupied by the control assembly 30 and the limiting assembly 40. Eventually, the main unit of the clothes dryer is thick and not thin and light enough. When the main unit is installed on the indoor ceiling, the main unit is significantly protruding relative to the surface of the indoor ceiling.

[0033] In view of this, the traction rope winding and unwinding device 100 of the present utility model adopts the following improvement: the housing assembly 10 constructs a receiving space 111, the control assembly 30 is located in the receiving space 111, and the limiting assembly 40 is located in the receiving space 111. Specifically, the stroke associated part 41 and the trigger part 42 are both located in the receiving space 111. With this arrangement, the present utility model overcomes the problem that the control assembly 30 and the limiting assembly 40 protrude outside the housing assembly 10 in the existing similar products, that is, the control assembly 30 and the limiting assembly 40 no longer occupy the space outside the housing assembly 10, and the envelope size of the traction rope winding and unwinding device 100 is reduced and closer to the envelope size of the housing assembly 10 itself. When the traction rope winding and unwinding device 100 of the present utility model is used as a part of the main unit of the clothes dryer, the overall structure of the main unit can be thinner, lighter and more flat than the existing thick and bloated main unit.

[0034] Refer to Figure 1 、 Figure 3, in some embodiments, the housing assembly 10 includes an upper cover 11 and a lower cover 12 that are butt - joined. The driver 22 is fixedly connected to the upper cover 11 and the lower cover 12. A winding space is formed by enclosing between the upper cover 11 and the lower cover 12. The winding wheel 21 further includes a shaft body segment 213 that is coaxially arranged with and fixedly connected to the winding portion. The shaft body segment 213 is rotatably connected to the upper cover 11 and the lower cover 12. The winding portion is received in the winding space between the upper cover 11 and the lower cover 12. The upper cover 11 is provided with a receiving cavity 1111 for forming a receiving space 111, and is further provided with a shaft - passing hole 114 that communicates the receiving cavity 1111 with the winding space. The receiving cavity 1111 is opened on the side of the upper cover 11 facing away from the lower cover 12, and forms an open - mouth on the side of the upper cover 11 facing away from the lower cover 12. The shaft body segment 213 passes through the upper cover 11 through the shaft - passing hole 114 and extends close to the receiving cavity 1111. The traction rope winding and unwinding device 100 further includes a transmission wheel 50 provided on the shaft body segment 213. The transmission wheel 50 is located in the receiving cavity 1111 and is connected to the stroke - associated portion 41.

[0035] Optionally, referring to Figure 1 and Figure 3 , both the control component 30 and the limiting component 40 located in the receiving cavity 1111 are not higher than the opening of the receiving cavity 1111. In other words, neither the control component 30 nor the limiting component 40 protrudes from the side of the upper cover 11 facing away from the lower cover 12.

[0036] Optionally, referring to Figure 3 and Figure 5 , the transmission wheel 50 is a transmission gear provided at one end of the shaft body segment 213 relatively far from the winding portion. The stroke - associated portion 41 includes a toothed ring 411 located in the receiving space 111 and rotatably connected to the second mounting portion 113. Inner meshing teeth are formed on the inner wall of the toothed ring 411. The transmission wheel 50 is surrounded by the toothed ring 411 and meshes with the inner meshing teeth. The number of teeth of the inner meshing teeth is much more than the number of teeth of the transmission gear. The transmission gear, the shaft body segment 213 and the winding portion share the same rotational angular velocity. The linear velocity of the rotation of the transmission gear is much smaller than the linear velocity of the winding portion. A fixed transmission ratio is formed between the transmission gear and the toothed ring 411. Therefore, the conversion ratio between the angular stroke of the rotation of the winding wheel 21 and the rotational stroke of the toothed ring 411 relative to the housing assembly 10 is determined. In other words, there is a one - to - one correspondence between the angular stroke of the rotation of the winding wheel 21 and the angular rotational stroke of the toothed ring 411 relative to the housing assembly 10.

[0037] In some other embodiments, the transmission wheel 50 can also be fixedly connected to the shaft body segment 213 in an integrally formed manner.

[0038] Optionally, referring to Figure 3 , the transmission wheel 50 is not higher than the opening of the receiving cavity 1111, that is, the transmission wheel 50 does not protrude from the side of the upper cover 11 facing away from the lower cover 12.

[0039] Optionally, the second mounting portion 113 may be a fixed mounting shaft fixedly disposed within the receiving cavity 1111, and the gear ring 411 is rotatably connected to the fixed mounting shaft and can rotate about the axis of the fixed mounting shaft.

[0040] It can be understood that in other embodiments, the transmission wheel 50 may also be replaced with a friction wheel, and the gear ring 411 may also be replaced with a friction ring, and the friction wheel and the friction ring are frictionally connected. Of course, other forms of transmission connections may also be formed between the transmission wheel 50 and the stroke associated portion 41, as long as there is a definite conversion ratio relationship between the angular stroke of the wire winding wheel 21 and the rotational stroke of the gear ring 411 relative to the housing assembly 10.

[0041] Furthermore, referring to Figure 1 , the triggering portion 42 is disposed on the outer peripheral side of the gear ring 411, and the triggering portion 42 can rotate synchronously with the gear ring 411 relative to the housing assembly 10, that is, the triggering portion 42 and the gear ring 411 share the same rotational angular velocity. The control assembly 30 includes a pressure sensing switch 31 located within the receiving space 111 and mounted on the first mounting portion 112. The pressure sensing switch 31 is located on the outer peripheral side of the gear ring 411 and is also electrically connected to the driver 22. Assuming that the gear ring 411 can continuously rotate relative to the housing assembly 10, the triggering portion 42 will periodically pass by and act on the pressure sensing switch 31. Optionally, the triggering portion 42 acts on the pressure sensing switch 31 in a manner of contacting and applying pressure. When the triggering portion 42 rotates with the gear ring 411 and contacts the pressure sensing switch 31, the pressure sensing switch 31 controls the driver 22 to stop operating, thereby controlling the wire winding wheel 21 to stop rotating. After the pressure sensing switch 31 is acted upon by the triggering portion 42, a control command is generated to control the driver 22 to stop operating.

[0042] Optionally, the closest distance from the pressure sensing switch 31 to the axis of rotation of the gear ring 411 is S1, and the distance from the end of the triggering portion 42 to the axis of rotation of the gear ring 411 is S2, where S1 < S2. The axis of rotation of the gear ring 411 is the axis of the fixed mounting shaft. The end of the triggering portion 42 refers to the end of the triggering portion 42 that is farthest from the outer peripheral side of the gear ring 411, and is the part where the triggering portion 42 contacts the pressure sensing switch 31 and applies pressure to the pressure sensing switch 31. The pressure sensing switch 31 includes an elastic member that can move elastically, and the shortest distance from the elastic member to the axis of the fixed mounting shaft is the closest distance S1 from the pressure sensing switch 31 to the axis of rotation of the gear ring 411. When the end of the triggering portion 42 contacts the elastic member, the elastic member is compressed and moves away from the fixed mounting shaft. After the triggering portion 42 leaves the pressure sensing switch 31, the elastic member rebounds, and the distance from the elastic member to the axis of the fixed mounting shaft returns to S1. Such a setting can enable the triggering portion 42 to smoothly contact and apply pressure to the pressure sensing switch 31.

[0043] Furthermore, referring to Figures 1 to 2 、 Figures 4 to 5, a first avoidance cavity 211 is formed at one end of the wire reel 21 facing away from the lower cover 12. Specifically, the first avoidance cavity 211 is formed at one end of the wire winding portion facing away from the lower cover 12, that is, at one end of the wire winding portion relatively close to the upper cover 11 and the sunk platform 1101. The upper cover 11 includes a cover plate and the sunk platform 1101. The edge of the lower cover 12 matches the edge of the cover plate and is spliced and fixed. The sunk platform 1101 protrudes from the side of the cover plate close to the lower cover 12 and extends convexly towards the wire winding assembly 20. The depth of the first avoidance cavity 211 is not less than the height of the sunk platform 1101 protruding from the cover plate, so as to ensure that there is no interference between the sunk platform 1101 and the wire winding portion. When observing the housing assembly 10 from the side of the upper cover 11 facing away from the lower cover 12, one end of the sunk platform 1101 facing away from the wire winding assembly 20 sinks into the first avoidance cavity 211 to form a receiving cavity 1111. One end of the sunk platform 1101 facing away from the lower cover 12 forms the bottom wall of the receiving cavity 1111. The first mounting portion 112 and the second mounting portion 113 are fixed on the bottom wall of the receiving cavity 1111. Specifically, both the first mounting portion 112 and the second mounting portion 113 are fixed on one end of the sunk platform 1101 facing away from the wire reel 21.

[0044] Further, the housing assembly 10 further includes a positioning platform 1102 protruding from one end of the sunk platform 1101 facing the wire reel 21. A second avoidance cavity 212 is formed at the bottom of the first avoidance cavity 211 to accommodate the positioning platform 1102. A shaft body section 213 protrudes from the bottom of the second avoidance cavity 212. The wire reel 21 further includes a positioning bearing 214. The inner ring and the outer ring of the positioning bearing 214 are respectively connected to the shaft body section 213 and the positioning platform 1102. Refer to Figures 3 to 4 , one end of the sunk platform 1101 facing the wire reel 21 is the end of the sunk platform 1101 facing the lower cover 12. A bearing installation groove communicating with the wire winding space is formed at one end of the positioning platform 1102 facing the lower cover 12. The through-shaft hole 114 and the bearing installation groove are coaxially arranged, so as to realize the coaxiality of the shaft body section 213 and the bearing installation groove. The outer ring of the positioning bearing 214 is fixedly matched with the inner wall of the bearing installation groove. The bottom of the first avoidance cavity 211 is formed by the wire winding portion. The through-shaft hole 114 penetrates through the positioning platform 1102 and the sunk platform 1101. One end of the through-shaft hole 114 communicates with the bearing installation groove, and the other end communicates with the receiving cavity 1111. The shaft body section 213 penetrates through the through-shaft hole 114 to pass through the positioning platform 1102 and the sunk platform 1101. One end of the shaft body section 213 relatively far away from the wire winding portion extends into the receiving cavity 1111 and is installed with a transmission wheel 50, so as to be connected to the stroke associated portion 41 through the transmission wheel 50.

[0045] With such a setting, the traction rope winding and unwinding device 100 of the present utility model can not only be compatible with the control assembly 30 and the limiting assembly 40 without increasing the size of the traction rope winding and unwinding device 100 in the axial direction of the wire reel 21, but also be compatible with the positioning bearing 214 to maintain the stable posture of the shaft body section 213 of the wire reel 21.

[0046] Optionally, as Figure 1 , Figure 3 shown, the upper cover 11 and the lower cover 12 are stacked and installed along the axis of the wire winding wheel 21, the receiving space 111 and the wire winding space are arranged in layers along the axis of the wire winding wheel 21, the axis of the wire winding wheel 21 is the axis of the shaft body section 213, and the extending direction of the axis of the wire winding wheel 21 is the thickness direction of the housing assembly 10, which is also equivalent to the thickness direction of the traction rope winding and unwinding device 100. The transmission wheel 50, the first mounting portion 112, the second mounting portion 113, the control assembly 30 and the limiting assembly 40 are all located in the receiving space 111 in the axial direction of the wire winding wheel 21 and do not protrude from the side of the upper cover 11 facing away from the lower cover 12. Generally speaking, the traction rope winding and unwinding device 100 is more similar to a cuboid structure and is more suitable for the cuboid-shaped clothes drying machine main unit. By receiving the control assembly 30 and the limiting assembly 40 in the receiving space 111, the dimensions of the traction rope winding and unwinding device 100 and the main unit in the axial direction of the wire winding wheel 21 are limited, making the traction rope winding and unwinding device 100 and the main unit more flattened, thereby obtaining a more slender and lightweight body structure.

[0047] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0048] Those of ordinary skill in the art of this technology should recognize that the above embodiments are only used to illustrate the present invention and are not used as a limitation of the present invention. As long as it is within the spirit and scope of the present invention, appropriate changes and variations made to the above embodiments fall within the scope of protection of the present invention.
