Description

Technical Field

[0001] The present application relates to the technical field of clothes dryers, and in particular to a cord winder and a household appliance. Background Art

[0002] At present, the dryers on the market are cleaning household appliances that evaporate the moisture in clothes instantly by blowing hot air into the clothes cover. They are suitable for daily washing, care and drying, and are especially suitable for use in humid areas or in weather such as haze and rainy seasons.

[0003] In the existing clothes dryer, the main dryer is arranged at the bottom, and the clothes to be dried placed in the clothes cover are located above the main dryer. The main dryer draws the air with lower outside temperature into the air duct, and then the lower temperature air is heated by the heating element to form hot air and blown upward. The hot air blows toward the clothes to be dried to gradually dry them, and the hot air is finally discharged from the exhaust holes on the clothes cover.

[0004] At present, most of the clothes dryer main units are large in size. Although they can be disassembled and installed, the installation steps are cumbersome, and they take up a large space after installation. It is difficult to store them after disassembly, which is difficult to meet the current requirements of fast drying and portability and space saving. For this reason, some clothes dryer main units adopt a foldable body structure, which can reduce the storage volume when folded and increase the drying capacity when unfolded, solving the contradiction between large drying capacity and small storage volume in the existing technology.

[0005] However, when the dryer main unit is folded or unfolded, the wires inside the dryer main unit will be pulled along with the movement of the main unit, thereby causing the wires inside the dryer main unit to stretch or shrink.

[0065] See also Figure 1 and Figure 2 A household appliance provided in one embodiment of the present application includes a fixed component 200 and a movable component 300. The movable component 300 is movably connected to the fixed component 200 so that the movable component 300 can move relative to the fixed component 200, thereby realizing function switching of the household appliance.

[0066] The household appliance may be a clothes dryer, a fan, a heater, or other household appliances with relatively movable parts. When the household appliance is a clothes dryer, the movable part 300 moves relative to the fixed part 200 to achieve folding and unfolding of the clothes dryer. When the household appliance is also a fan that can shake its head, the fixed part 200 is the base of the fan, and the movable part 300 is the head of the fan. The swing of the head relative to the base can achieve air discharge in different directions.

[0067] For ease of description, the following description is only based on an embodiment in which the household appliance is a clothes dryer. Specifically, during the folding or unfolding process of the clothes dryer, the movable component 300 is rotatable relative to the fixed component 200 around a rotation axis, and a movable air outlet 301 is formed on the movable component 300, and a fixed air outlet 201 is formed on the fixed component 200. When the clothes dryer is in the folded state, Figure 1As shown, the movable air outlet 301 and the fixed air outlet 201 are both located between the movable component 300 and the fixed component 200. In this way, when the clothes dryer main unit is folded, it can not only reduce the occupied space, but also close the movable air outlet 301 and the fixed air outlet 201, thereby preventing external dust and debris from entering the movable air outlet 301 and causing blockage, thereby affecting the air outlet effect.

[0068] When the movable part 300 rotates a certain angle relative to the fixed part 200, the clothes dryer main unit can be in an unfolded state. Figure 2 As shown, when the clothes dryer main unit is in the unfolded state, that is, Figure 2 In the state of the clothes dryer main unit shown, the clothes dryer main unit is placed on a horizontal plane, and the movable air outlet 301 and the fixed air outlet 201 are oriented in a vertical direction.

[0069] During actual use of the dryer main unit, the unfolded dryer main unit is arranged under the clothes cover of the dryer so that the movable air outlet 301 can be directed toward the clothes hung on the clothes cover, thereby drying the clothes on the clothes cover with hot air discharged through the movable air outlet 301 and the fixed air outlet 201.

[0070] In actual use, the power supply interface of the dryer main unit is arranged on the fixed component 200, and the fixed component 200 is provided with a power supply module electrically connected with the power supply interface. The external power enters the power supply module through the power supply interface, and is finally distributed to various electrical components in the dryer main unit through the power supply module.

[0071] Specifically, in order to enable the active air outlet 301 to discharge hot air, an active heating element is provided in the active component 300. The active heating element is electrically connected to the power supply module through a connecting wire. The active heating element is arranged in an air duct connected to the active air outlet 301 to heat the air flow passing through it to form hot air, which is finally discharged from the active air outlet 301 for drying clothes.

[0072] During the unfolding and folding process of the dryer main unit, the movable component 300 will produce relative movement with the fixed component 200, thereby increasing or decreasing the distance between the movable heating element and the power supply module. As the wiring distance between the movable heating element and the power supply module changes, the connecting wire will be pulled by the movable heating element and elongated or contracted, thereby causing friction between the connecting wire and the shell of the dryer main unit, causing wear of the connecting wire, resulting in a reduction in the service life of the connecting wire and an increase in the safety risks of the dryer main unit during use.

[0073] To this end, in some embodiments of the present application, refer to Figure 3 , Figure 4 and Figure 5The household appliance further comprises a cord winder 100, see Figure 6 and Figure 7 The cable winder 100 includes a disc assembly 110 and a winding assembly 130. The disc assembly 110 is disposed on the fixed component 200, and the winding assembly 130 is disposed on the reel assembly 110. The connecting wire is wound on the winding assembly 130. The winding assembly 130 is configured to be able to reel in or release the wire as the movable component 300 moves relative to the fixed component 200, that is, when the clothes dryer main unit is folded, the winding assembly 130 releases the connecting wire, and when the clothes dryer main unit is unfolded, the winding assembly 130 reels the wire.

[0074] Specifically, when the household appliance is a clothes dryer main unit, part of the connecting wire between the movable heating element and the power supply module is wound on the winding assembly 130, and during the folding process of the clothes dryer main unit, the wiring distance between the movable heating element and the cord winder 100 increases, and the connecting wire wound in the cord winder 100 is released as the clothes dryer main unit is folded, so that more part of the connecting wire is used to connect the cord winder 100 and the movable power supply element.

[0075] During the unfolding of the dryer main unit, the wiring distance between the movable heating element and the cable winder 100 is reduced, and the excess portion of the connecting wire will be wound up by the cable winder 100, thereby avoiding friction between the excessively long connecting wire and the housing of the dryer main unit, thereby increasing the service life of the wire body and reducing safety hazards during the use of the dryer main unit.

[0076] It is understandable that in some other embodiments, when the clothes dryer is folded, the wiring distance between the active heating element and the cable winder 100 decreases, and when the clothes dryer is unfolded, the wiring distance between the active heating element and the cable winder 100 increases. For this reason, in this embodiment, the winding assembly 130 is configured to reel in the connecting wire as the clothes dryer is folded, and release the connecting wire as the clothes dryer is unfolded.

[0077] It should be noted that the above-mentioned connecting wire can be but not limited to connecting the heating element and the power supply module. In some other embodiments, the connecting wire can also connect the power supply module and the display screen, or the connecting wire connects the power supply module and the blower motor, etc. The connecting parts of the connecting wire can be selected according to the actual use requirements, as long as they are used to connect the parts in both the fixed part 200 and the movable part 300, and no limitation is made here. For the convenience of description, the following only describes the case where the connecting wire connects the movable heating element and the power supply module.

[0078] The cable winder 100, through the winding assembly 130, reels the excessively long portion of the connecting wire into the cable winder 100 when the movable part 300 moves relative to the fixed part 200, or releases the connecting wire when the movable part 300 moves relative to the fixed part 200 to cooperate with the movement of the movable part 300. In this way, the cable winder 100 reels and releases the connecting wire, thereby preventing the connecting wire from being stretched or contracted during the movement of the movable part 300 relative to the fixed part 200, reducing the friction between the connecting wire and the housing of the household appliance, thereby increasing the service life of the wire body and reducing the potential safety hazards of the household appliance during use.

[0079] In some embodiments of the present application, refer to Figure 8 The winding assembly 130 includes a hairpin 131, which is curled around a curling axis, which is parallel to or coincides with the rotation axis of the movable host rotating around the fixed component 200. The connecting wire is wound around the surface of the hairpin 131, so that the connecting wire can be rolled up on the hairpin 131 or released from the hairpin 131 by tightening and loosening the hairpin 131.

[0080] In order to facilitate the winding of the connecting wire on the hair condition 131, a mounting groove extending longitudinally along the winding direction is provided on the surface of the hair condition 131. The connecting wire is located in the mounting groove, and the inner wall of the mounting groove is used to limit the connecting wire to prevent the connecting wire from falling off the hair condition 131.

[0081] Specifically, during the folding process of the clothes dryer main unit, the wiring distance between the movable heating element and the cord winder 100 increases, and the movable heating element will pull the connecting wire to move. During the movement, the connecting wire will tighten the launching condition 131, thereby reducing the radius of the launching condition 131, so that more connecting wires can be pulled out from the cord winder 100 to meet the demand of the movable heating element for longer connecting wires.

[0082] During the unfolding of the clothes dryer main unit, the wiring distance between the movable heating element and the cable winder 100 is reduced, and the tightened hairpin 131 is gradually loosened, so that the radius of the hairpin 131 is gradually increased, and the expanded hairpin 131 drives the wire body to expand together, so that the excess part of the connecting wire can be rolled up by the hairpin 131, and then the excess part of the connecting wire is stored in the cable winder 100.

[0083] In some embodiments, in order to enable the cable winder 100 to reel in a sufficient length of the connecting wire, the winding condition 131 includes a plurality of winding conditions, each of which is coiled around the same coiling axis, and the connecting wire is sequentially coiled around each winding condition 131. In this way, by winding the connecting wire simultaneously through the plurality of winding conditions 131, the length of the connecting wire wound in the cable winder 100 can be made longer, so as to meet the larger angle of opening and closing of the movable part 300 relative to the fixed part 200.

[0084] Among them, all the hairpins 131 are arranged at intervals along the axial direction of the winding axis, so that the multiple hairpins 131 are arranged in a three-dimensional state, which improves the space utilization while ensuring the winding length of the connecting wire. Specifically, if there is only one hairpin 131, in order to ensure that the connecting wire of sufficient length is wound, it is necessary to increase the diameter of the hairpin 131, but it will cause the space occupied by the hairpin 131 to increase. By using multiple hairpins 131 arranged at intervals, the winder 100 can wind longer connecting wires, and the installation of the hairpin 131 is more flexible, so that the overall volume of the winder 100 can be more streamlined.

[0085] Specifically in some embodiments, in one of two adjacent hairsprings 131, in a natural state, the inner diameter of one hairspring 131 is larger than the outer diameter of the other hairspring 131. The inner diameter of the hairspring 131 refers to the diameter of the innermost coil of the spring, and the outer diameter of the hairspring 131 refers to the diameter of the outermost coil of the hairspring 131. In this way, after passing through the outer end of one hairspring 131, the connecting wire directly enters the inner end of the other hairspring 131, thereby reducing the bending angle of the connecting wire in the winding device 100 and reducing the friction of the wire body in the winding device 100.

[0086] Specifically in one embodiment, the winding assembly 130 includes two springs 131. For ease of description, one of the springs 131 is defined as an inner spring 134, and the other spring 131 is defined as an outer spring 135. In a natural state, the outer diameter of the inner spring 134 is smaller than the inner diameter of the outer spring 135, so that the inner space of the outer spring 135 can be used for the installation of the inner spring 134.

[0087] Furthermore, in order to install the inner spring 134, the disc assembly 110 includes a mounting post 111, the axis of the mounting post 111 is parallel to or coincides with the winding axis, the inner spring 134 is mounted on the top of the mounting post 111, and the outer spring 135 is sleeved on the mounting post 111. In this way, the inner spring 134 is arranged above or below the outer spring 135, so that the winding assembly 130 is in a three-dimensional state, thereby saving lateral installation space and helping to reduce the volume of the winder.

[0088] It should be noted that in some other embodiments, the winding assembly can also be a winding reel that can rotate around a rotation axis, and the connecting wire is wound on the winding reel. The winding reel is driven by a motor or other means, and when the clothes dryer is folded, the connecting wire is released by forward rotation, and when the clothes dryer is unfolded, the connecting wire is rolled up by reverse rotation.

[0089] During actual use, when the clothes dryer main unit is folded, the connecting wire needs to be pulled out from the cord reel. Since friction is still generated between the connecting wire and the hair condition 131, if the connecting wire is pulled out too quickly, it is easy to cause greater wear between the connecting wire and the hair condition 131, and it will also cause damage to the connecting wire, affecting the service life of the connecting wire.

[0090] Furthermore, when the clothes dryer is unfolded, since the unfolding is a relatively rapid process, a large amount of excess length of the connecting wire will appear in a short period of time. If the cord reel cannot be retracted immediately, the excess connecting wire will rub against the housing of the clothes dryer during the reel reeling process, which will also cause wear on the connecting wire and affect the service life of the connecting wire.

[0091] To this end, in some embodiments of the present application, refer to Figure 7 , Figure 8 The cable winder 100 further includes a damping assembly 150, which is disposed on the disc assembly 110 and connected to the winding assembly 130. The damping assembly 150 is configured to provide a resisting force to hinder the movement of the winding assembly 130 when the winding assembly 130 releases the connection wire, and to provide a driving force to drive the winding assembly 130 to move when the winding assembly 130 reels the connection wire.

[0092] Thus, when the clothes dryer is folded, the damping assembly 150 reduces the speed at which the winding assembly 130 releases the connecting wire, thereby preventing the connecting wire from being worn due to the connecting wire being released too quickly. When the clothes dryer is unfolded, the damping assembly 150 increases the speed at which the winding assembly 130 reels the connecting wire, thereby allowing the connecting wire to be quickly retracted into the reel, thereby reducing friction between the connecting wire and the clothes dryer during the reeling process.

[0093] In some embodiments, the damping assembly 150 includes a torsion spring 151, one end of which is connected to the disc assembly 110, and the other end is connected to the winding assembly 130. When the winding assembly 130 releases the connecting wire, the torsion spring 151 accumulates elastic force, thereby hindering the movement of the winding assembly 130 through its own elastic force, thereby reducing the speed at which the connecting wire is withdrawn from the winding assembly 130. When the winding assembly 130 reels the connecting wire, the torsion spring 151 releases the elastic force, thereby increasing the speed at which the winding assembly 130 reels the connecting wire through the elastic force of the torsion spring 151.

[0094] When the winding assembly 130 includes only one hairpin 131, the hairpin 131 can be connected to the torsion spring 151 at one end of its own curling axis, and the curling axis of the hairpin 131 coincides with the axis of the torsion spring 151. In this way, when the hairpin 131 is tightened, the torsion spring 151 is driven to move, and the torsion spring 151 is used to prevent the hairpin 131 from being tightened, and when the hairpin 131 is loosened, the torsion spring 151 can increase the loosening speed of the hairpin 131.

[0095] When the winding assembly 130 includes a plurality of spring elements 131, the spring elements 131 cannot be directly connected to the torsion spring 151 due to the height difference between them. Therefore, in some embodiments, the damping assembly 150 further includes a torsion member 152, which is rotatably disposed on the disc assembly 110 around the curling axis and connected to the torsion spring 151, and one end of each spring element 131 in its own curling direction is connected to the torsion member 152.

[0096] In this way, when all the triggering conditions 131 are tightened, the torsion member 152 will be driven to rotate, and the torsion member 152 will drive the torsion spring 151 to rotate, so that the torsion spring 151 prevents the torsion member 152 from rotating, and the torsion member 152 prevents each triggering condition 131 from rotating. When all the triggering conditions 131 are loosened, the torsion spring 151 will drive the torsion member 152 to reverse, so that the triggering conditions 131 are driven to loosen through the torsion member 152, thereby increasing the loosening speed of the triggering conditions 131.

[0097] Specifically in one embodiment, the winding assembly 130 includes two springs 131, namely the inner spring 134 and the outer spring 135 mentioned above, the disk body assembly 110 includes a mounting column 111, the axis of the mounting column 111 is parallel to or coincides with the curling axis, the inner spring 134 is installed at the top of the mounting column 111, the torsion spring 151 is arranged on the mounting column 111, the torsion member 152 is arranged on the outer periphery of the torsion spring 151, and the outer spring 135 is arranged on the outer periphery of the torsion member 152.

[0098] In this way, the position of the inner spring 134 is raised by the mounting column 111, so that the inner spring 134 will not interfere with the torsion spring 151, so that both the inner spring 134 and the outer spring 135 can be connected to the torsion piece 152. At the same time, the inner end of the outer spring 135 arranged on the outer periphery of the torsion piece 152 in the curling direction can also be connected to the torsion piece 152 without interfering with the inner spring 134 and the torsion spring 151.

[0099] Further, in order to facilitate the installation of the inner spring 134 and to limit the position of the inner spring 134, refer to Fig. 9The inner wall of the torsion piece 152 is provided with a limiting column 153, and the inner spring 134 is arranged around the limiting column 153, so that the inner spring 134 is positioned by the limiting column 153. Furthermore, the axis of the limiting column 153 coincides with the curling axis, and the inner end of the inner spring 134 in the curling direction is connected to the limiting column 153, so that the inner spring 134 can drive the torsion piece 152 to rotate.

[0100] Specifically in some embodiments, in order to allow the connecting wire on the inner mainspring 134 to be transmitted to the outer mainspring 135, the torsion piece 152 is provided with a first wire passing hole 154, and the first wire passing hole 154 passes through from the outer wall of the torsion piece 152 to the inner wall of the torsion piece 152. The connecting wire passing through the inner mainspring 134 enters the second wire passing hole 112, and then the connecting wire passes through the second wire passing hole 112 and enters the outer mainspring 135.

[0101] Furthermore, in order to allow the external connection wire to enter the inner spring 134, a second wire hole 112 is provided at the top of the mounting column 111, and the connection wire connected to the movable heat conductor is passed into the reel through the second wire hole 112. At the same time, since the inner spring 134 is provided at the top of the mounting column 111, the connection wire passed through the second wire hole 112 can directly enter the inner spring 134.

[0102] In some embodiments of the present application, the disc assembly 110 includes a disc box 113 and a disc cover 114. A mounting column 111 is formed in the disc box 113. The torsion piece 152 and the outer spring 135 are both arranged in the disc box 113. The torsion spring 151 and the inner spring 134 are arranged in the torsion piece 152. The disc cover 114 is covered on the disc box 113 and is provided with an avoidance hole 118. The torsion piece 152 is passed through the avoidance hole 118. In this way, the disc cover 114 is used to fix the outer spring 135 in the disc box 113. The torsion piece 152 can not only be used to hinder and drive the movement of the winding assembly 130, but also can be used to fix the torsion spring 151 and the inner spring 134 in the disc box 113. At the same time, the torsion piece 152 can be extended out of the disc cover 114 through the avoidance hole 118, so that the volume of the disc cover 114 and the disc box 113 can be reduced, and then the volume of the entire winder 100 can be reduced.

[0103] The disk box 113 further includes a wire outlet hole 115 connected to the inside, and the connecting wire is passed through the wire outlet hole 115, so that after the disk cover 114 is covered on the disk box 113, the connecting wire can also pass through the disk box 113. The disk body assembly 110 further includes a guide shaft 116, which is rotatably arranged on the disk box 113 around a guide axis and is located at the wire outlet hole 115, and the guide axis intersects with the axis direction of the wire outlet hole 115. In this way, the guide shaft 116 can not only adjust the direction of the connecting wire passing through the winder 100, but also reduce the friction between the connecting wire and the disk body assembly 110 by rotating the guide shaft 116 itself.

[0104] Specifically, when the connecting wire passes through the wire outlet hole 115, the connecting wire will contact the outer peripheral surface of the guide shaft 116. During the movement of the movable component 300, the connecting wire will be drawn out of the wire outlet hole 115 or retracted into the wire outlet hole 115, so the connecting wire will generate relative movement with the wire shaft. Since the guide shaft 116 is rotatable, when the connecting wire moves relative to the guide shaft 116, the connecting wire will drive the guide shaft 116 to rotate, thereby reducing the friction between the connecting wire and the guide shaft 116 through the rotation of the guide shaft 116, further improving the service life of the connecting wire.

[0105] Optionally, the guide shaft 116 is a rubber shaft, so as to further reduce the friction between the connecting wire and the disc assembly 110 by the softness of the rubber shaft itself. Furthermore, the rubber shaft includes a plurality of guide shafts 116, and all guide shafts 116 are arranged at intervals at the outlet hole 115 along the circumferential direction of the disc assembly 110. In actual use, the connecting wire is passed between two guide shafts 116, so that when the clothes dryer is folded or unfolded, the opposite sides of the connecting wire can abut against the rubber shaft, thereby reducing the friction between the connecting wire and the disc assembly 110 through the rubber shaft.

[0106] In actual use, the assembly method of the winder 100 is to first place the disk box 113 on a plane, then fix the torsion spring 151 to the disk box 113, and then fix the inner spring 134 to the mounting post 111 of the disk box 113, and then place the torsion piece 152 on the disk box 113 to wrap the torsion spring 151 and the inner spring 134, and then fix the outer spring 135 to the disk box 113, and then place the rubber shaft on the raised points on the disk box 113 in turn, and finally fix the disk cover 114 to the disk box 113, and fix the outer spring 135 and the rubber shaft, and the installation of the winding disk is completed.

[0107] The wiring sequence of the connecting wire in the winding reel is as follows: after the connecting wire is passed through the second wire passing hole 112, the first step is to wind the connecting wire onto the inner spring 134 in sequence from the inside to the outside; the second step is for the wire passing through the inner spring 134 to first pass through the first wire passing hole 154 and then be wound onto the outer spring 135 in sequence from the inside to the outside of the outer spring 135; the third step is for the connecting wire passing through the outer spring 135 to pass between two of the rubber shafts to complete the wiring of the winder 100. The winding action needs to be performed simultaneously with the assembly of the winder 100.

[0108] In some embodiments of the present application, the cable winder 100 includes two, and the two cable winders 100 are arranged on the fixed component 200 at intervals along the direction of the rotation axis, and the connecting wire passes through the fixed component 200, each cable winder 100, and the movable component 300 in sequence. In this way, the connecting wire is wound and released by the two cable winders 100 at the same time, so that a longer connecting wire can be stored in the two cable winders 100, and the clothes dryer main unit can be wound and released by the two cable winders 100 at the same time when folding and storing, so that the winding and releasing of the connecting wire is faster, and the friction between the connecting wire and the clothes dryer main unit is further reduced.

[0109] Specifically, when the connecting wire connects the driving module and the active heating element, the connecting wire extends from the driving module into one of the winders 100, then leaves from the wire outlet hole 115 of the winder 100, enters into another winder 100, and finally leaves from the wire outlet hole 115 of the other winder 100 and connects to the active heating element.

[0110] Among them, see Fig.10 The fixed part 200 is provided with a wire clip 210, and the connecting wire located in the fixed part 200 is partially fixed to the fixed part 200 through the wire clip 210. Since both the two wire winders 100 are arranged on the fixed part 200, when the movable part 300 moves relative to the fixed part 200, the wire winder 100 will not move relative to the fixed part 200, so the connecting wire in the fixed part 200 will not be stretched or contracted, so the wire clip 210 can be used to fix the connecting wire located in the fixed part 200.

[0111] Further, see Fig.11The movable part 300 is provided with a wiring hole 310, and the part of the connecting wire located in the movable part 300 is passed through the wiring hole 310. Since part of the connecting wire in the movable part 300 will stretch or shrink during the movement of the movable part 300 relative to the fixed part 200, the connecting wire in the movable part 300 is not fixed, and the position of the connecting wire is only partially limited by the wiring hole 310 to avoid affecting the stretching or shrinking of the connecting wire.

[0112] In some embodiments of the present application, in order to allow hot air to be blown out of both the fixed air outlet 201 and the movable air outlet 301, the fixed component 200 further includes a fixed housing 220, a blast drive 230, a fixed blast member 240, a fixed air duct, and a fixed volute. The blast drive 230, the fixed air duct, and the fixed volute are all arranged on the fixed housing 220. The fixed blast member 240 is located in the fixed volute and is connected to one end connected to the fixed air duct. The fixed air outlet 201 is located at the other end of the fixed air duct. The blast drive 230 is connected to the fixed blast member 240 to drive the fixed blast member 240 to rotate in the fixed volute, thereby forming an airflow, which is discharged from the fixed air outlet 201 after passing through the fixed air duct.

[0113] Furthermore, the movable component 300 includes a movable shell 320, a movable blowing member 330, a movable volute and a movable air duct. The movable shell 320 is rotatably mounted on the fixed shell 220 around a rotation axis. The movable air duct and the movable volute are both arranged on the movable shell 320. The movable blowing member 330 is located in the movable volute and is connected to one end of the movable air duct. The movable air outlet 301 is located at the other end of the movable air duct.

[0114] Among them, the blowing drive member 230 has two driving shafts 231, one of which is connected to the fixed blowing member 240, and the other is connected to the movable blowing member 330, so as to drive the movable blowing member 330 to rotate in the movable volute, thereby forming an airflow, which passes through the movable air duct and is discharged from the movable air outlet 301.

[0115] Specifically in some embodiments, the disc assembly 110 of the cable winder 100 is fixed on the blast drive 230, so that the cable winder 100 can be arranged as much as possible between the fixed component 200 and the movable component 300. Optionally, the blast drive 230 is a motor, and the disc assembly 110 of the cable winder 100 is fixed to the housing of the motor by fasteners such as bolts.

[0116] In order to avoid interference between the cable winder 100 and the drive shaft 231, a through hole 117 is provided on the disc assembly 110 and is arranged along the rotation axis direction. The drive shaft 231 is arranged through the through hole 117, so that the drive shaft 231 passes through the cable winder 100 and is connected to the fixed blower or the movable blower 330. When there are two cable winders 100, the two drive shafts 231 are respectively arranged through the through holes 117 of the two cable winders 100, so that the two cable winders 100 are fixedly mounted on the housing of the motor.

[0117] During the installation of the entire dryer host, the fixed shell 220 is first placed on a plane, and then the movable shell 320 is installed on the shaft ribs of the fixed shell 220. Then the blower drive 230 is installed on the fixed shell 220, and then the two winders 100 with wiring are installed on the motor. At the same time, the connecting wires on the back of the winding drum need to be passed through the wire holes of the movable shell 320, and the connecting wires between the two winding drums need to be connected. Finally, the connecting wires coming out from the sides of the winding drum are respectively led to the various electrical components in the movable shell 320 and the fixed shell 220, thus completing the wiring layout of the dryer host.

[0118] The above-mentioned cable winder 100 has at least the following advantages:

[0119] When the clothes dryer is folded or unfolded, the winding assembly 130 reels the excessively long portion of the connecting wire into the wire winder 100, and when the clothes dryer is unfolded or folded, the connecting wire is released to cooperate with the unfolding or folding of the clothes dryer. In this way, the winding and releasing of the connecting wire by the wire winder 100 can prevent the connecting wire from being stretched or contracted during the folding or unfolding of the clothes dryer, reduce the friction between the connecting wire and the housing of the clothes dryer, increase the service life of the wire body, and reduce the potential safety hazards during the use of the clothes dryer.

[0120] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0121] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
