Description

Technical Field

[0001] This application relates to a garment processing device. Background Technology

[0002] Clothing handling equipment is a general term for washing machines that wash clothes (the objects to be washed or dried), dryers that dry clothes, and other devices that can perform both washing and drying of clothes.

[0003] Typically, a washing machine includes: an outer tub for storing water; a washing drum disposed inside the outer tub for storing clothes; and a drive unit (washing drive unit) for rotating the washing drum; a dryer includes: a drying drum for storing clothes; a drive unit (drying drive unit) for rotating the drying drum; and a heat exchange unit for removing moisture from the clothes by supplying air to the drying drum.

[0004] Typically, the washing drive unit includes: a stator fixed to the outer tub to form a rotating magnetic field; a rotor that rotates through the rotating magnetic field; and a rotating shaft passing through the outer tub and connecting the washing drum and the rotor; while the drying drive unit includes: a motor; a pulley fixed to the rotating shaft of the motor; and a transmission belt (power transmission unit) that connects the rotational motion of the pulley to the drying drum.

[0005] The washing drive unit is configured such that the motor's rotating shaft is directly connected to the washing drum and rotor. For washing or spin-drying clothes, the washing drive unit needs to control the washing drum's rotation speed at a high level or change its rotation direction. When the motor's rotating shaft is directly connected to the washing drum and rotor, it allows for easy control of both the washing drum's speed and rotation direction.

[0006] On the other hand, existing drying drive units generally employ a structure where the drying drum and the motor's rotating shaft are connected by a power transmission component such as a drive belt. This is because, in dryers, the necessity of maintaining a high rotational speed of the drying drum or changing its rotation direction is relatively low, so rotating the drying drum via a power transmission component such as a drive belt is acceptable. However, if the rotational speed and direction of the drying drum could be changed, the movement of clothes inside the drum could be controlled, thus potentially leading to shorter drying times and improved drying performance.

[0007] An existing dryer has a drying drive unit (publication number 10-2020-0065931) that connects a rotor and a drying drum via a reducer (power transmission unit). The drying drive unit is configured such that an input shaft connected to the rotor and an output shaft connected to the drying drum are coaxial, thus potentially reducing drying time or improving drying performance. However, it suffers from the following drawbacks: assembly of the drying drum and the reducer's output shaft is difficult, and assembly may reduce the durability of the reducer or the drying drum (damage to bolts on the reducer, damage to the output shaft, damage to the drying drum, etc.).

[0008] Furthermore, in existing dryers, the vibration of the drying drum, which is fixed to the output shaft of the reducer, is transmitted to the reducer, and the vibration transmitted to the reducer is then transmitted to the support body supporting the reducer. Therefore, the rigidity of the support body supporting the reducer needs to be set to attenuate or suppress the vibration of the drying drum (the vibration of the reducer) during the rotation of the drying drum.

[0009] While a thicker support can effectively suppress vibration of the drying drum, it also increases the manufacturing cost and weight of the garment handling device. Conversely, a thinner support cannot limit the vibration of the drying drum within a set range, thus posing a risk of damage to the support or reducer. Summary of the Invention

[0043] Hereinafter, embodiments of the garment handling apparatus will be described in detail with reference to the accompanying drawings.

[0044] Figure 1 This figure illustrates an example of a garment handling device 100, which may include: a housing 1; and a drum 2, rotatably disposed inside the housing, providing space for storing garments (items to be washed or dried). Figure 2 As shown, a drying section 3 can be provided inside the housing 1. The drying section 3 removes moisture from the clothes by supplying high-temperature dry air (air with a temperature higher than room temperature and a dryness level higher than indoor air) to the drum 2.

[0045] like Figure 2 As shown, the housing 1 includes: a front panel 11, forming the front surface of the garment handling device; and a base panel 17, forming the bottom surface of the garment handling device. An inlet 111 communicating with the roller 2 is provided on the front panel 11, and the inlet 111 can be blocked by a door 113.

[0046] A control panel 115 is provided on the front panel 11. The control panel 115 may include an input unit for receiving control commands from the user and a display unit for outputting information such as control commands that the user can select. The input unit may include: a power request unit for requesting power to the garment handling device; a process input unit for enabling the user to select a process from a plurality of processes; and an execution request unit for requesting the start of the process selected by the user.

[0047] The roller 2 can be configured as a hollow cylinder. For example... Figure 3 As shown, the roller 2 may include: a cylindrical roller body 21 with open front and rear sides; a front cover 22 forming the front side of the roller body 21; and a rear cover 23 forming the rear side of the roller body 21.

[0048] The front cover 22 may be provided with a roller inlet 221 that connects the inside of the roller body 21 with the outside, and the rear cover 23 may be provided with an air inlet 233 that allows external gas to flow into the roller body 21.

[0049] A lifting device 24 may also be provided on the drum body 21. The lifting device 24 is a component that allows the clothes to rise and fall repeatedly inside the drum. The lifting device 24 can be provided by a plate extending from the front cover 22 to the rear cover 23, protruding from the drum body 21 toward the rotation center of the drum 2 (protruding from the circumference of the drum toward the rotation center of the drum).

[0050] When the clothing processing device 100 is configured as a device for drying clothes only, the roller 2 may not be provided with a roller through hole that penetrates the roller body 21 in order to communicate the inside of the roller with the outside of the roller.

[0051] like Figure 4 As shown, the roller 2 can be rotatably fixed to at least one of the main body first support portion 12 and the main body second support portion 15. Figure 4 The figure shows an example in which the rear cover 23 is rotatably fixed to the second support part 15 of the main body via the power transmission part 6 described later, and the front cover 22 is rotatably connected to the first support part 12 of the main body.

[0052] The main body first support 12 can be provided as a support plate 121 fixed to the housing 1 and located between the front panel 11 and the front cover 22. The support plate 121 can be configured to be located between the front panel 11 and the front cover 22 by being fixed to the base panel 17. In this case, the rear side (the side facing the support plate) of the front panel 11 can be fixed to the support plate 121, while the lower end is fixed to the base panel 17.

[0053] The support plate 121 may include: a support plate through hole 122; a roller connecting body 123 connecting the support plate through hole 122 and the roller inlet 221; and a plate connecting body 125 connecting the support plate through hole 122 and the inlet 111. The support plate through hole 122 is a component configured to penetrate the support plate 121 and connect the inlet 111 and the roller inlet 221.

[0054] The roller connecting body 123 can be configured as a tube fixed to the rear side (the side facing the roller inlet in the space provided by the support plate 121). One end of the roller connecting body 123 can be configured to surround the through hole 122 of the support plate, and the free end of the roller connecting body 123 can be configured to support the front cover 22. That is, the free end of the roller connecting body 123 can be inserted into the roller inlet 221, or it can be configured to contact the free end (edge ​​of the roller inlet) of the front cover 22 forming the roller inlet 221. Figure 4 The figure shows an example of a situation where the free end of the roller connecting body 123 is in contact with the free end of the front cover 22.

[0055] The plate connecting body 125 can be provided by a tube fixed to the front side (facing the front panel of the space provided by the support plate 121). One end of the plate connecting body 125 can be configured to surround the through hole 122 of the support plate, and the other end of the plate connecting body 125 can be configured to be connected to the inlet 111. Thus, clothing supplied to the inlet 111 can move towards the roller body 21 through the plate connecting body 125, the through hole 122 of the support plate, the roller connecting body 123, and the roller inlet 221.

[0056] The support plate 121 may be provided with an exhaust port 126 for discharging air from inside the roller 2 to the outside of the roller. The filter 127 may be fixed to the exhaust port 126 in a detachable manner. The filter 127 may be configured in any structure, as long as it can filter out foreign objects in the air moving from the roller 2 to the exhaust port 126.

[0057] The support plate 121 may also be provided with a roller support portion 128 to prevent the roller 2 from sagging. The roller support portion can be fixed to the support plate 121 and support the roller 2 as a rotatable roller. Although, Figure 4 The illustration shows the roller support 128 configured to support the front cover 22, but the roller support 128 may also be configured to support the circumferential surface of the roller body 21.

[0058] The main body second support 15 can be provided as a fixing plate 151 fixed in the box 1 at a position spaced apart from the rear cover 23. Figure 5 The figure shows an example of a case where the fixing plate 151 is fixed to the base panel 17 and forms the rear side (rear side of the box) of the clothing handling device 100.

[0059] The fixing plate 151 may be provided with a drive unit mounting groove 152, which provides space for mounting the motor 5. The drive unit mounting groove 152 may be formed by bending the fixing plate 151 inward toward the rear cover 23 of the roller. The fixing plate 151 is provided with a fixing plate through hole 153, through which the shaft (output shaft) for rotating the roller 2 passes. The fixing plate through hole 153 may be located inside the drive unit mounting groove 152.

[0060] Compared to a structure where the open front and rear sides of the roller body 21 are rotatably connected to the support plate 121 and the fixing plate 151 respectively, as described above, when the roller 2 is composed of the roller body 21, a front cover 22 fixed to the roller body, and a rear cover 23 fixed to the roller body, the rigidity of the roller is increased. When the rigidity of the roller is increased, the deformation of the roller body 21 during roller rotation can be minimized. This minimizes the problem of clothing being trapped in the space between the roller body and the support plate, and between the roller body and the fixing plate, when the roller body 21 deforms (and thus minimizes the load on the motor).

[0061] like Figure 4 As shown, the drying unit 3 may include: an exhaust flow path 31 connected to the exhaust port 126; a supply flow path 32 that leads the air supplied from the exhaust flow path 31 to the drum body 21; and a heat exchange unit 34 disposed inside the exhaust flow path 31 to sequentially perform air dehumidification and heating.

[0062] The exhaust flow path 31 may include a first pipe 311 connected to the exhaust port 126, a second pipe 312 connected to the supply flow path 32, and a third pipe 313 connecting the first pipe 311 and the second pipe 312. The third pipe 313 may be fixed to the base panel 17.

[0063] The heat exchange section 34 can be installed in various ways, as long as it can sequentially dehumidify and heat the air flowing into the exhaust flow path 31. Figure 4 The diagram illustrates an example where the heat exchange section 34 is configured as a heat pump. Specifically, the heat exchange section 34 includes: a first heat exchanger (heat absorber) 341, which removes moisture from the air flowing into the exhaust passage 31; a second heat exchanger (heat generator) 343, disposed inside the exhaust passage 31, which heats the air that has passed through the heat absorber 341; and a fan 349, which directs the air discharged from the drum 2 through the heat absorber and the heat generator sequentially to the supply pipe 32.

[0064] The heat-absorbing part 341 and the heat-generating part 343 are arranged sequentially along the direction of air movement and are connected to each other through a refrigerant pipe 348 that forms a refrigerant circulation path. The refrigerant moves along the refrigerant pipe 348 through a compressor 345 located outside the exhaust path 31, and a pressure regulator 347 for adjusting the pressure of the refrigerant is provided in the refrigerant pipe 348.

[0065] like Figure 5 As shown, the air inlet 233 located on the rear cover 23 of the roller can be configured with a plurality of holes to surround the center of the rear cover 23 (the rotation center of the roller). In this case, the supply flow path 32 may include: a supply pipe 321 located on the fixed plate 151, forming a movement path for air discharged from the second pipe 312; and a first flow path forming part 323 and a second flow path forming part 324, which guide the air inside the supply pipe 321 to the air inlet 233.

[0066] The supply pipe 321 can be configured to bend through the fixing plate 151 in a direction away from the rear cover 23 to form a flow path (air movement path). In addition, the supply pipe 321 can be configured in an annular shape surrounding the drive unit mounting groove 152, and the outlet of the second pipe 312 can be configured to be connected to the circumferential surface of the supply pipe 321.

[0067] The first flow path forming part 323 can be configured as the outer circumferential surface of the ring formed by the air inlet 233 (the circumferential surface with the longer diameter among the two circumferential surfaces of the ring), and the second flow path forming part 324 can be configured as the inner circumferential surface of the ring formed by the air inlet 233 (the circumferential surface with the shorter diameter among the two circumferential surfaces of the ring).

[0068] The first flow path forming part 323 and the second flow path forming part 324 can be fixed to the rear cover 23 or to the supply pipe 321. Figure 5 The figure shows an example of the flow path forming parts 323 and 324 being fixed to the rear cover 23.

[0069] exist Figure 5 In this configuration, the free end of the first flow path forming portion 323 surrounds the outer circumferential surface of the flow path (annular flow path) formed by the supply pipe 321, and the free end of the second flow path forming portion 324 surrounds the inner circumferential surface of the flow path formed by the supply pipe 321. The first flow path forming portion 323 and the second flow path forming portion 324 can be made of rubber or felt, etc.

[0070] The motor 5 that generates the power required to rotate the roller 2 includes: a stator 51 located in the drive unit mounting slot 152, forming a rotating magnetic field; and a rotor 52 that rotates via the rotating magnetic field. The rotational motion of the rotor 52 is transmitted to the roller 2 through a power transmission unit 6 fixed to the fixed plate 151, and the stator 51 is fixed to the power transmission unit 6.

[0071] When the stator 51 is fixed to the power transmission section 6, it has the effect of maintaining the coaxiality of the input shaft 64 and the output shaft 65 provided in the power transmission section 6 (which can minimize the vibration of the garment handling device when the drum rotates and minimize the decrease in the durability of the power transmission section).

[0072] The mounting plate 151 may also be provided with a cover plate 19 to prevent the motor 5 from being exposed to the outside, thereby improving the motor's durability and preventing safety accidents by preventing the motor from being exposed to the external environment. Furthermore, the cover plate 19 may be configured in a shape that also prevents the supply pipe 321 from being exposed to the outside (a shape that surrounds the supply pipe). This not only minimizes heat leakage to the outside of the supply pipe 321, but also prevents potential safety accidents that may occur when the body comes into contact with the supply pipe 321.

[0073] The stator 51 includes: a ring-shaped core 511 with a through hole (core through hole) at the center; a plurality of support bars 513 that radiate outward from the outer circumferential surface of the core 511; an insulator 512 that insulates the core and the support bars; and a coil 514 configured to surround the support bars 513.

[0074] The rotor 52 may include: a disc-shaped rotor body 521; a rotor circumferential surface 522 extending from the edge of the rotor body 521 toward the fixing plate 515 and forming a space to accommodate the stator 51; and a plurality of permanent magnets 523 fixed on the rotor circumferential surface 522 with alternating N and S poles exposed.

[0075] Figure 6 This is a diagram showing an example of the power transmission section 6 that connects the rotor 52 and the rear cover 23 of the drum.

[0076] The power transmission unit 6 includes: a cover H, fixed to the fixing plate 151; an input shaft 64, rotatably fixed to the bottom surface (facing the direction of the rotor) of the cover H; an output shaft 65, rotatably fixed to the upper surface (facing the direction of the fixing plate) of the cover H; and a gear unit G, disposed inside the cover, for transmitting the rotational motion of the input shaft 64 to the output shaft 65.

[0077] The input shaft 64 can be configured with one end fixed to the rotor 52 and the other end located inside the cover H, and the output shaft 65 can be configured with one end fixed to the rear cover 23 and the other end located inside the cover H. The gear unit G is configured to connect one end of the input shaft 64 located inside the cover H and one end of the output shaft 65 located inside the cover.

[0078] Preferably, the cover H is located in a space separate from the space where the roller 2 is located (the space outside the box). This is to improve the durability of the power transmission unit 6 by minimizing the transfer of heat from inside the box (heat released from the roller or drying section) to the inside of the cover H.

[0079] The input shaft 64 can be coupled to the rotor body 521 via the shaft fixing part 54. The shaft fixing part 54 may include a shaft fixing hole 543 for fixing one end of the input shaft 64.

[0080] The output shaft 65 is inserted into the through hole 153 of the fixing plate and connected to the rear cover 23. The rear cover 23 may be provided with a shaft fastening part 25 to fix the output shaft 65. This is to distribute the stress acting on the center of the rear cover 23 when the output shaft 65 rotates. The specific structure of the shaft fastening part 25 will be described later.

[0081] The cover H may include: a cover body 62, which is a cylindrical shape with a hollow interior and has an opening on the side facing the fixing body 151; and a cover 63, which is fixed to the cover body 62 and blocks the opening.

[0082] The main body 62 of the cover can be configured to form a receiving space 621 for mounting the gear unit G. The receiving space 621 can be formed by a cover base 62a to which the input shaft 64 is fixed and a cover circumferential surface 62b extending from the edge of the cover base 62a toward the cover cover 63.

[0083] like Figure 7 As shown, the cover body 62 is provided with an input shaft support portion 625 extending from the cover base 62a toward the rotor 52. The input shaft support portion 625 can be provided as a tube surrounding an input shaft through hole 626 that passes through the cover body 62.

[0084] The input shaft 64, inserted into the input shaft through hole 626, is rotatably supported in the input shaft support portion 625 by input shaft bearings 628 and 629. The input shaft bearings may include: a first input shaft bearing 628, fixed to the input shaft support portion 625; and a second input shaft bearing 629, fixed inside the input shaft through hole 626, located between the first input shaft bearing 628 and the rotor 52.

[0085] The cover 63 can be of any shape, as long as it can be opened and closed through the opening in the main body 62 of the cover. Figure 7 The figure shows an example in which the cover 63 is configured as a disc-shaped cover body 631. The cover 63 can be configured to be fixed to the cover body 62 by a cover fixing plate 623 provided on the circumferential surface 62b of the cover body.

[0086] The cover 63 may include: an output shaft through hole 632 configured to penetrate the cover body 631; and a tubular output shaft support portion 635 extending from the cover body 631 toward the fixing plate 151 and surrounding the output shaft through hole 632.

[0087] The output shaft support portion 635 may be provided with output shaft bearings 638 and 639 for rotatably fixing the output shaft 65 to the output shaft through hole 632.

[0088] The output shaft bearing may include a first output shaft bearing 638 and a second output shaft bearing 639, which are fixed to the output shaft support 635 and located inside the output shaft through hole 631.

[0089] The gear unit G may include: a gear ring 66, fixed to the circumferential surface 62b of the cover and located in the receiving space 621; a driving gear 69, fixed to the input shaft 64 and located inside the receiving space 621; a retainer 67, located inside the receiving space 622, with the other end of the output shaft 65 fixed to the retainer 67; and a driven gear 68, rotatably fixed to the retainer 67, connecting the driving gear 69 and the gear ring 66.

[0090] The ring gear 66 may include: a gear body 661, fixed to the circumferential surface 62b of the cover; a gear body through hole 663, configured to pass through the gear body; and gear teeth 665, arranged along the inner circumferential surface of the gear body.

[0091] The retainer 67 may include: a first base 671 located inside the gear body through hole 663, with one end of the output shaft 65 fixed to the first base 671; a second base 672 located inside the gear body through hole 663, with a base through hole 673 in the center of the second base 672; and a connecting shaft 675 connecting the first base and the second base to form the rotation shaft of the driven gear 68. Since the output shaft 65 is fixed to the first base 671, whether the output shaft 65 rotates depends on whether the retainer 67 rotates.

[0092] The driven gear 68 may be composed of a plurality of gears rotatably fixed to the connecting shaft 675. The attached figure is an example of the driven gear being composed of a first driven gear 681, a second driven gear 682, and a third driven gear 683.

[0093] The input shaft 64 is inserted into the base through hole 673 and forms a coaxial structure with the output shaft 65. The gear teeth of the driving gear 69 are located in the space formed between the driven gears and mesh with the gear teeth of the driven gears 682, 682, 683.

[0094] The operation of the power transmission unit 6 described above will now be explained. The input shaft 64 rotates when the rotor 52 rotates. When the driving gear 69 is driven to rotate by the input shaft 64, the driven gears 681, 682, and 683 meshing with the driving gear 69 also rotate. Since the driven gears 681, 682, and 683 are in a state of meshing with the gear ring 66 fixed to the main body 62 of the housing, the retainer 67 and the output shaft 65 rotate when the driven gear 68 rotates, and the roller 2 fixed to the output shaft 65 also rotates.

[0095] The power transmission unit 6 with the above structure is rotatably fixed to the fixing plate 151 via the cover mounting unit 7.

[0096] like Figure 8 As shown, the cover mounting part 7 can be configured as a support part 74 that is fixed to the fixing plate 151 and can rotate within a predetermined angle range. Figure 8 The figure shows an example in which the support 74 is rotatably fixed to the fixing plate 151 by the first fixing body 71 and the second fixing body 72.

[0097] like Figure 9 As shown, the first fixing body 71 and the second fixing body 72 are components that form an installation space 73 for accommodating the support part 74.

[0098] The first fixing body 71 and the second fixing body 72 can be separated from each other and fixed to the fixing plate 151. In contrast, the first fixing body 72 can be fixed to the fixing plate 151, and the second fixing body 72 can also be fixed to the first fixing body 71.

[0099] The first fixing body 71 is provided with: a first fixing body through hole 711, which communicates with the fixing plate through hole 153; and a support part first cover 712, which is configured to surround the first fixing body through hole 711 and form part of the installation space 73.

[0100] The second fixing body 72 is provided with: a second fixing body through hole 721, which communicates with the fixing plate through hole 153 (and communicates with the first fixing body through hole); and a support portion second cover 722, which is configured to surround the second fixing body through hole 721, forming part of the installation space 73. The installation space 73 is formed by the combination of the support portion first cover 712 and the support portion second cover 722.

[0101] The support portion 74 includes: a generally spherical support body 741 located inside the mounting space 73; and a support body through hole 742 configured to penetrate the support body 741.

[0102] The support body 741, which is located in the mounting space 73, is situated within the through hole 153 of the fixing plate. Thus, when the support body 741 is fixed in the mounting space 73, the through hole 742 of the support body is located within the through hole 153 of the fixing plate.

[0103] The output shaft support 635 of the power transmission unit is inserted into the through hole 742 of the support body, and the output shaft support 635 is fixed to the support body 741 by the support body fixing part 743. A thread is provided on the circumferential surface of the output shaft support 634, and the support body fixing part 743 can be configured as a nut fastened to the thread.

[0104] The cover mounting portion 7 may also be provided with a guide 75 that forms a rotation path for the support body 741. The guide 75 may be configured to form a path for the support body 741 to move along the height direction of the fixing plate 151.

[0105] That is, the guide 75 is a component that allows the support body 741 to rotate within a plane (ZY plane) extending from the fixing plate 151 toward the support plate 121, which includes a vertical line H passing through the center of the through hole 153 of the fixing plate (a vertical line passing through the center of the through hole of the second fixing body and a vertical line passing through the center of the through hole of the first fixing body). Therefore, as Figure 10 As shown, the guide 75 is a component that prevents the support body 741 from rotating in a plane (XZ plane) parallel to the base panel 17.

[0106] like Figure 9 As shown, the guide 75 may include: a first protrusion 751 disposed in the mounting space 73 and protruding toward the support body 741; a second protrusion 752 disposed in the mounting space and protruding toward the support body 741; a first groove 753 disposed along the circumferential surface of the support body 741 to form a movement path for the first protrusion 751; and a second groove 754 disposed along the circumferential surface of the support body 741 to form a movement path for the second protrusion 752.

[0107] The first protrusion 751 and the second protrusion 752 need to be positioned 180 degrees apart from the center of the through hole 742 of the support body. That is, the first protrusion 751 can be positioned to contact the uppermost end of the support body 741, and the second protrusion 752 can be positioned to contact the lowermost end of the support body 741.

[0108] The first protrusion 751 is disposed on at least one of the first cover 712 and the second cover 722 of the support portion, and the second protrusion 752 may be disposed on at least one of the first cover 712 and the second cover 722 of the support portion.

[0109] Although the above embodiments are described based on the case where the support body 741 is set in a spherical shape, the shape of the support body 741 can vary, as long as the support body can perform the above-described movements.

[0110] In the garment handling apparatus 100 with the above-described structure, the rear cover 23 of the roller is fixed to the output shaft 65, and the front cover 22 is mounted on the roller support 128. Although vibration may occur in the roller 2 when it rotates, the power transmission part 6, to which the output shaft 65 is fixed, is fixed to the fixing plate 151 by the cover mounting part 7, thus reducing the transmission of roller vibration to the fixing plate 151. Therefore, the garment handling apparatus 100 can minimize the decrease in the durability of the fixing plate 151.

[0111] On the other hand, the garment handling device 100 may also be provided with a displacement limiting part 8 to limit the rotation angle of the support body 741. When the rotation angle of the support body 741 is limited by the displacement limiting part 8, the downward droop of the front surface (front cover 22) of the roller (the angle formed by a straight line passing through the rotation center of the roller and parallel to the length direction of the roller and the horizontal line) can be adjusted.

[0112] The displacement limiting part 8 may include a fastening body 81, which passes through the fixing plate 151 and is fixed to the cover H.

[0113] like Figure 11 As shown, one end of the fastening body 81 is located between the rear cover 23 and the fixing plate 151, while the other end is fixed to the cover H. A connector 637 that engages with the other end of the fastening body 81 may be provided in the cover H.

[0114] A head 82 is provided at one end of the fastening body 81. The head 82 is located between the rear cover 23 and the fixing plate 151 and prevents the fastening body 81 from separating from the fixing plate 151.

[0115] The stator 51 can be fixed to the connector 637 or directly fixed to the fastening body 81. Figure 11 The figure shows an example of a situation where the stator 51 is fixed to the fastening body 81 by bolts connecting the insulator 512 and the fastening body 81.

[0116] The fastening body 81 penetrates the fixing plate 151 through the mounting hole 84. When the fastening body 81 is configured to penetrate only the fixing plate 151, the mounting hole 84 becomes a first mounting hole 841 provided in the fixing plate 151. On the other hand, when the fastening body 81 is configured to penetrate both the first fixing body 71 and the fixing plate 151, the mounting hole 84 is composed of the first mounting hole 841 provided in the fixing plate and a second mounting hole 842 penetrating the first fixing body 71.

[0117] Figure 11 This diagram illustrates a configuration where the fastening body 81 is arranged to pass through the fastening body bracket 87, the first fixing body 71, and the fixing plate 151. In this configuration, the mounting hole 84 includes a first mounting hole 841 in the fixing plate, a second mounting hole 842 passing through the first fixing body 71, and a third mounting hole 843 passing through the fastening body bracket 87. The diameter of the fastening body 81 needs to be set smaller than the diameter of the mounting hole 84 so that the cover H can rotate within a predetermined angle range (so that the fastening body can move inside the mounting hole).

[0118] The fastening body bracket 87 is a component used to minimize the risk of damage to the fixing plate 151 due to the fastening body 87. For example... Figure 9 As shown, the fastening main support 87 can be arranged in a disc shape and fixed to the first fixing main body 71.

[0119] The fastening main support 87 is provided with a support through hole 871, which is configured to communicate with the through hole 153 of the fixing plate and expose the installation space 73 to the outside.

[0120] The third mounting hole 843 can be configured as a plurality of through holes surrounding the bracket through hole 871, and the fastening body bracket 87 can also be provided with a fastening body guide 872 extending from the third mounting hole 843 toward the first fixing body 71.

[0121] like Figure 11 As shown, the fastening body guide 872 can be configured to insert into the second mounting hole 842 and the first mounting hole 841 and guide the linear movement of the fastening body 81. In this case, it is necessary to set the diameter of the fastening body 81 to be smaller than the diameter of the fastening body guide 872 so that the cover H can rotate within a predetermined angle range (so that the fastening body can move inside the fastening body guide).

[0122] To enable the cover H to rotate around the support body 741 (rotating in the YZ plane) and return to its initial position, limiting the displacement of the front cover 22 of the roller and preventing the cover H from colliding with the fixing plate 151, a vibration damper 85 may also be provided in the displacement limiting part 8. The vibration damper 85 may be a ring-shaped rubber or spring disposed on the fastening body 81 and located between the fixing plate 151 and the connector 637.

[0123] In the garment processing device 100 with the above structure, since the cover H of the power transmission unit 6 can rotate around the support body 741, even if the roller 2 vibrates in the YZ plane, the external force can be minimized to the output shaft 65, output shaft bearings 638 and 639, cage 67 and gear unit G provided in the power transmission unit 6.

[0124] Furthermore, in the clothing handling device 100 with the above-described structure, since the cover H can rotate around the support body 741 (because the vibration of the roller is consumed as the kinetic energy of the cover), the vibration of the roller transmitted to the fixing plate 151 can be minimized (improving the durability of the fixing plate).

[0125] As mentioned above, in order to distribute the stress acting on the center of the rear cover 23 when the output shaft 65 rotates (in order to minimize the decrease in the durability of the rear cover), the output shaft 65 is connected to the rear cover 23 of the roller via the shaft fastener 25.

[0126] That is, such as Figure 8 As shown, the rear cover 23 can be configured to have a rear cover through hole 231, and the shaft fastening part 25 can be fixed to the rear cover 23 and block the rear cover through hole 231.

[0127] The shaft fastening part 25 may include: a first fastening body 251, fixed to the rear cover 23; a connecting body 255, extending from the first fastening body 251 and inserted into the through hole 231 of the rear cover; and a second fastening body 252, fixed to the connecting body 255 and located inside the roller 2. The second fastening body 252 is provided with a fastening through hole 253 for the output shaft 65 to be inserted.

[0128] The output shaft 65 includes: a fastening shaft 651 located inside the housing H and fixed to the retainer 67; and a fixing shaft 652 extending from the fastening shaft 651 and inserted into the fastening portion through hole 253. A thread 653 is provided on the circumferential surface of the fixing shaft 652. In this case, the output shaft 65 can be fixed to the shaft fastening portion 25 by a nut 256 engaging with the thread 653.

[0129] The assembly of the roller 2 and the output shaft 65 is performed through the following process: fixing the fixing plate 151 on which the power transmission part 6 is installed to the base panel 17; inserting the output shaft 65 into the fastening part through hole 253; fixing the position of the front cover 22 by fixing the support plate 121 to the base panel 17; and connecting the output shaft 65 and the shaft fastening part 25 by the nut 256.

[0130] Although the output shaft 65 remains inserted into the fastening through hole 253 before the support plate 121 is fixed to the base panel 17, the front cover is not supported by the roller support 128. However, in the above-described garment handling apparatus, the fastening through hole 253 and the support body 741 allow the front cover 22 to be temporarily placed on the upper surface of the exhaust passage 31 or the base 17, etc. Therefore, the garment handling apparatus 100 can reduce the risk of decreased durability of the power transmission unit 6 when the shaft fastening part 25 and the output shaft 65 are combined.

[0131] On the other hand, the diameter of the connecting body 255 can be set to decrease as it moves from the first fastening body 251 toward the second fastening body 252. When the shape of the connecting body 255 is set as described above, the fixing shaft 652 is guided along the surface of the connecting body 255 to the fastening through hole 253, thus shortening the time required to insert the fixing shaft 652 into the fastening through hole 253.

[0132] To prevent the shaft fastening part 25 from protruding into the roller 2, this embodiment may also include a fastening part cover 27. The fastening part cover 27 can be of any shape, as long as it can block the rear cover through hole 231 and prevent the shaft fastening part 25 from being exposed.

[0133] The fastening cover 27 can be configured to be fixed to the output shaft 65 by bolts 273, wherein the bolts 273 are inserted into the cover through hole 271 and fixed to the fastening groove 654 of the fixed shaft 652.

[0134] The above-described garment processing device can be modified and implemented in various forms, therefore the scope of protection of this application is not limited to the above embodiments.
