Description

Technical Field

[0001] The present invention relates to a balancer, a garment handling apparatus equipped with a balancer, and a method for manufacturing a balancer, and more specifically, to a balancer that compensates for the imbalance of a roller, a garment handling apparatus equipped with a balancer, and a method for manufacturing a balancer. Background Technology

[0002] A garment handling device refers to a washing machine that washes clothes during a washing cycle and a dryer that dries clothes during a drying cycle. While washing machines and dryers are typically separate units, garment handling devices that can perform washing and drying simultaneously are available to overcome space limitations and improve user convenience.

[0003] In order to perform the washing cycle, the laundry handling device includes a cabinet, an outer drum for storing water, a roller that provides space for holding the items to be processed, a drive unit that is fixed to the outer drum and rotates the roller, a support unit that supports the outer drum, a water supply unit that supplies water to the outer drum, and a drain unit that discharges water from the outer drum.

[0004] On the other hand, in order to perform the drying cycle, the garment handling device is provided with a flow path section that draws air from the inside of the outer drum and resupplyes it to the outer drum, and a heat exchange section provided in the flow path section that sequentially dehumidifies and heats the air.

[0005] That is, in existing garment handling equipment, there are devices for washing cycles and devices for drying cycles inside the cabinet, so that washing cycles and drying cycles can be selectively executed according to the user's needs.

[0006] Existing garment handling devices with the above-described structure have limitations in application to commercial garment handling systems that require frequent and rapid processing of large quantities of garments. Specifically, commercial garment handling systems require processing space to accommodate heavy and bulky garments, and also need heat exchange units for rapid washing and drying. Therefore, it is difficult to simultaneously house washing and drying units within a cabinet of limited volume. While it is possible to install both washing and drying units simultaneously by designing a large cabinet, this presents manufacturing and handling difficulties.

[0007] Therefore, for commercial garment handling equipment, the combination or layout between washing and drying equipment has become one of the important design considerations.

[0008] On the other hand, existing commercial garment processing devices use rollers that are relatively larger than those in household garment processing devices to provide space for the items to be processed. In the current situation, a structure that can strengthen such rollers is needed.

[0009] In addition, the rollers in existing commercial garment handling devices are currently made by stamping metal sheets of a predetermined thickness using large stamping dies corresponding to the sheet material forming the roller.

[0010] Therefore, the manufacturing of stamping dies incurs relatively high costs, and there is a current need for a manufacturing method that can reduce the cost of stamping dies used to process such rollers.

[0011] In addition, existing commercial garment handling equipment may experience eccentric rotation due to imbalances in the items being processed. To compensate for this, a balancer can be installed on the roller. The shape design of this balancer installed on the roller is one of the core design considerations.

[0012] This balancer is made in the following way: using synthetic resin material, two or more components are formed by injection molding to create a moving space for the balancer components to move, and after the balancer components are inserted, the components are welded together by ultrasonic welding process.

[0013] On the other hand, when this type of balancer is injection molded, depending on the thickness, size and other conditions, it may shrink and deform when the synthetic resin is cooled. This shrinkage and deformation will cause the balancer to be uneven in roundness and flatness (degree of flatness). When ultrasonic welding of various parts is performed, deformation may occur in the injection molded parts.

[0014] Therefore, there is a current need for a balancer and a balancer manufacturing method that can improve the roundness and flatness of the balancer due to shrinkage during injection molding when ultrasonic welding is performed. Summary of the Invention

When the height of the first front panel 11 and the first rear panel 13 is set to be higher than the plurality of side panels 121, 122, when the second processing device 100b is installed in the installation space 15, it not only facilitates the positioning and fixing of the second processing device 100b, but also has the effect of reducing the overall height of the clothing processing device 100.

[0129] Furthermore, if the first front panel 11 is configured to be higher than the side panels 121 and 122, the height of the garment handling device 100 can be increased by a minimum while the first front panel 11 provides space for other devices (such as a detergent storage unit). The first front panel 11 can be configured to have the same height as the first rear panel 13, or it can be configured to have a different height than the first rear panel 13.

[0130] A first control unit 19 may be provided inside the first cabinet 1 for controlling at least one of the first processing device 100a and the second processing device 100a. The first control unit 19 may be configured to receive control signals from the input section of the control panel 112 or to transmit control signals requesting display information to the display section of the control panel 112. The first control unit 19 may be fixed to the first rear panel 13 and located inside the first cabinet 1.

[0131] Inside the first cabinet 1, a receiving section 2 may be provided for forming a washing space or a drying space for the object to be processed. The receiving section 2 may have an outer cylinder 2a that forms a space for water and a path for air movement, and a roller 2b that is rotatably disposed inside the outer cylinder to form a processing space for receiving the object to be processed.

[0132] The outer cylinder 2a can be configured to include an outer cylinder body 21, which provides space for storing water and is fixed inside the first cabinet 1 by an outer cylinder support 23.

[0133] The outer cylinder body 21 can be configured as a hollow cylindrical shape. The outer cylinder body 21 can be configured to include a front surface 21a of the outer cylinder in the direction of the first front panel 11, a rear surface 21b of the outer cylinder in the direction of the first rear panel 13, and a circumferential surface 21c of the outer cylinder connecting the front surface and the rear surface of the outer cylinder body.

[0134] The front surface 21a of the outer cylinder may be provided with an inlet 211 that communicates with the interior of the roller 2b and an installation tube 212 that is configured to enclose the inlet 211 and protrudes from the front surface 21a of the outer cylinder toward the through hole 111 of the cabinet.

[0135] That is, the mounting tube 212 is configured as a cylindrical shape protruding from the front surface 21a of the outer cylinder toward the first front panel 11, and the inlet 211 is formed as a hole penetrating the front surface 21a of the outer cylinder and located inside the mounting tube 212.

[0136] The aforementioned mounting pipe 212 not only provides installation space for the injection section or the outer cylinder air supply section described later, but can also serve as a means to guide the object to be processed, which is inserted into the aforementioned roller 2b through the aforementioned cabinet through hole 111, to the aforementioned inlet 211.

[0137] The aforementioned inlet 211 can be opened and closed via a door 22 that is rotatably fixed to the front surface 21a of the outer cylinder. The door 22 is rotatably fixed to the outer cylinder body 21 rather than to the first front panel 11. Therefore, preferably, the cabinet through hole 111 is configured in a size and position that does not interfere with the rotation of the door 22 (for opening or closing the inlet).

[0138] That is, when the aforementioned inlet 211 is closed, the aforementioned door 22 remains exposed to the outside of the aforementioned first cabinet 1 through the aforementioned cabinet through hole 111. However, when the aforementioned inlet 211 is opened, the aforementioned door 22 can rotate outwards from the aforementioned first cabinet 1 through the aforementioned cabinet through hole 111.

[0139] Furthermore, in the second processing device 100b, a frame panel 62 may be provided inside the front panel 67 (second front panel) forming the front side of the second cabinet 6. The frame panel 62 may be configured to support the flow paths 7 and 8 (see reference 1). Figure 7 (a portion of the space.)

[0140] The second front panel 67 can be configured to wrap around the frame panel 62 to prevent the frame panel 62 from being exposed to the outside. In addition, in order to facilitate user access to the frame panel 62, the second front panel 67 can be rotatably fixed to the support frame 61, the frame panel 62, or the upper panel 66, etc.

[0141] The frame panel 62 may be provided with a first panel door 624 and a second panel door 626, which are rotatably fixed to the frame panel 62, which connects the interior and exterior of the second cabinet 6 by opening and closing.

[0142] Figure 3This is an exploded perspective view showing a first processing apparatus according to an embodiment of the present invention. Figure 4 This is a side perspective view showing a first processing apparatus according to an embodiment of the present invention.

[0143] like Figures 3 to 4 As shown, the outer tube 2a can be supported by a first support body 231 forming the bottom surface of the garment handling device 100, a second support body 235 for fixing the outer tube body 21 and located on the upper part of the first support body 23, a damper 236 and a spring 237 disposed between the first support body 231 and the second support body 235.

[0144] The outer cylinder 2a may be provided with a door mounting portion 224 for fixing the door 22 to the front surface 21a of the outer cylinder. The door mounting portion 224 may be configured to include a first mounting cover 225 fixed to the front surface 21a of the outer cylinder and covering the mounting tube 212, and a second mounting cover 226 fixed to the first mounting cover 225 and providing space for mounting the hinge 227 of the door. The door mounting portion 224 may be provided with an inlet communication hole 228 to prevent the inlet 211 from being closed by the door mounting portion 224.

[0145] The outer cylinder 2a can be connected to the second processing device 100b via the outer cylinder air supply section 24 and the outer cylinder exhaust section 25. That is, the second processing device 100b can be detachably connected to the outer cylinder air supply section 24 and the outer cylinder exhaust section 25.

[0146] The outer cylinder air supply section 24 can be configured to supply air to the interior of the outer cylinder body 21 through the mounting pipe 212, and the outer cylinder exhaust section 25 can be configured to exhaust the air inside the outer cylinder body 21 to the outside of the outer cylinder 2a through the outer cylinder circumferential surface 21c.

[0147] The aforementioned outer cylinder air supply section 24 may be configured to include a first air supply hole 241 and a second air supply hole 242 provided on the aforementioned mounting pipe 212, and a distribution pipe 243 that guides air to each of the aforementioned air supply holes 241 and 242.

[0148] The first air supply port 241 and the second air supply port 242 can be configured to penetrate the mounting pipe 212 and communicate with the inlet port 211. The distribution pipe 243 can be configured to include a connecting pipe 243a connected to the second processing device 100b, a first branch pipe 243b that guides a portion of the air flowing into the connecting pipe to the first air supply port 241, and a second branch pipe 243c that guides a portion of the air flowing into the connecting pipe to the second air supply port 242.

[0149] In order for the garment processing device 100 to wash or dry various items, the volume of the outer drum body 21 and the drum 2b needs to be designed to be large. The drum 2b needs to be able to rotate inside the body 21 while being supported by the rear side 21b of the outer drum; therefore, in order to design a large volume for the drum 2b, the durability of the outer drum body 21 is crucial. Therefore, the outer drum body 21 can be made of metal.

[0150] When the outer cylinder body 21 is made of metal, it is preferable that the mounting pipe 212 is also made of metal, but the distribution pipe 243 may be made of a different material than the mounting pipe 212. From a cost and time perspective, it is more advantageous to mold the distribution pipe 243, which has a first branch pipe 243b and a second branch pipe 243c, from a material such as plastic compared to metal. Therefore, when the distribution pipe 243 and the mounting pipe 212 are made of different materials, the first processing apparatus 100a may further include a bracket 244 for connecting the distribution pipe 243 to the mounting pipe 212.

[0151] The aforementioned distribution pipe 243 can be configured as a flow path protruding from the aforementioned mounting pipe 212 toward the aforementioned second processing device 100b. On the other hand, the free end of the aforementioned connecting pipe 243a (the part for connecting the second processing device) can be configured to be exposed to the outside of the aforementioned first processing device 100a through the mounting space 15 of the aforementioned first cabinet 1.

[0152] That is, the free end of the connecting pipe 243a can be configured to be located at a point higher than at least any one of the upper ends of the first front panel 11, the first rear panel 13, and the first side panels 121 and 122. This is to facilitate the connection of the first processing device 100a and the second processing device 100b.

[0153] The outer cylinder exhaust section 25 can be configured as an exhaust pipe protruding from the outer cylinder circumferential surface 21c toward the second processing device 100b. That is, the outer cylinder exhaust section 25 can be configured as an exhaust pipe protruding toward the mounting space 15 formed on the upper surface of the first processing device 100a.

[0154] The free end of the outer cylinder exhaust section 25 (the part used to connect the second processing device 100b) can be configured to be located at a point higher than at least one of the upper ends of the first front panel 11, the first rear panel 13, and the first side panels 121 and 122. This is to facilitate the connection of the first processing device 100a and the second processing device 100b.

[0155] Unlike the above, the free end of the outer cylinder exhaust section 25 can also be configured to be located at a point lower than the upper end of the side panel 12. This is to reduce the height of the garment handling device 100.

[0156] The door 22 may be configured to include a door frame 221 that is rotatably fixed to the hinge 227, a door frame through hole 222 that passes through the door frame, and a door window 223 that is fixed to the door frame 221 and closes the door frame through hole.

[0157] The aforementioned through hole 222 in the door frame can be formed at a position corresponding to the aforementioned inlet 211 (the position communicating with the inlet), and the aforementioned door / window 223 can be made of a light-transmitting material. In this case, the user can inspect the interior of the aforementioned roller 2b from the outside of the aforementioned first processing device 100a.

[0158] The aforementioned door and window 223 may be configured to include a first window 223a that is fixed to the door frame 221 in a manner that exposes it to the outside through the cabinet through hole 111, and a second window 223b that is fixed to the door frame 221 in a manner that is located inside the mounting tube 212.

[0159] The first window 223a may be made of a portion of the glass that forms the first front panel 11 through the cabinet through hole 111, and the second window 223b may be made of glass that protrudes from the door frame 221 toward the inlet 211.

[0160] The outer tube body 21 can receive water through the water supply section 4, and the water inside the outer tube body 21 is discharged to the outside of the clothing handling device 100 through the drainage section 28.

[0161] The aforementioned drainage section 28 may be configured to include a drain pipe 281 for guiding water inside the outer cylinder body 21 to the outside of the first cabinet 1. The aforementioned drain pipe 281 may be a flexible tube with one end fixed to the lower space of the outer cylinder circumferential surface 21c (located in the outer cylinder circumferential surface area below the horizontal line penetrating the center of the inlet) and the other end penetrating the first rear panel 13.

[0162] The drain pipe 281 can be configured to discharge water inside the outer cylinder body 21 to the outside of the first cabinet 1 by gravity, or it can be configured to discharge water inside the outer cylinder body 21 to the outside of the first cabinet 1 by a drain pump. Figure 4 An example of the former case is shown. In this case, the drainage section 28 may also be provided with a drainage valve 282 that controls the opening and closing of the drainage pipe 281 according to the control signal of the first control section 19.

[0163] The aforementioned drainage section 28 may also be equipped with a drainage filter for filtering the water flowing into the aforementioned drainage pipe 281, and the drainage filter may be configured to be detachable from the aforementioned drainage pipe 281. The aforementioned drainage valve 282 and the aforementioned drainage filter may be located in positions exposed to the outside when the aforementioned second panel 114 is separated from the first processing device 100a.

[0164] Figure 5 This is a split cross-sectional perspective view showing the main components of a first processing apparatus according to an embodiment of the present invention. Figure 6 This is a rear perspective view showing the internal structure of a first processing device according to an embodiment of the present invention.

[0165] like Figures 5 to 6 As shown, the roller 2b is configured as a hollow cylindrical shape. This roller 2b may include a front roller plate 26b forming the front of the roller 2b, a roller body 26a forming the outer peripheral surface of the roller 2b, a rear roller plate 26c forming the rear of the roller 2b, and a reinforcing plate 26d for strengthening the rear roller plate 26c.

[0166] The front roller plate 26b may have a roller inlet 261b that communicates with the inlet 211. The circumferential surface of the roller body 26a may have a plurality of roller through holes 263a that communicate with the interior of the outer cylinder body 21. The rear roller plate 26c may be connected to a roller shaft 260a that is connected to the drive unit 27 described later.

[0167] In addition, multiple lifting components 26e can be provided inside the drum body 26a. When the drum body 26a rotates, the object to be processed can be repeatedly lifted and lowered inside the drum body 26a (which can improve the washing power).

[0168] The roller body 26a can be rotated via the roller shaft 260a and the drive unit 27. The roller shaft 260a is configured to be fixed to the rear side of the roller body 26a and pass through the rear side 21b of the outer cylinder. The drive unit 27 can be configured to be located outside the outer cylinder body 21 to rotate the roller shaft 260a.

[0169] In addition, a front balancer 26f and a rear balancer 26f can be provided on the outer side of the front roller plate 26b and the outer side of the rear roller plate 26c to compensate for the imbalance caused by the eccentricity of the object to be processed when the roller 2b rotates.

[0170] On the other hand, the detailed structure and assembly of the roller 2b and the front and rear balancers 26f will be described in detail with reference to the other accompanying drawings after the description of the first processing device 100a and the second processing device 100b is completed.

[0171] The outer cylinder 2a forms a space for storing water, and simultaneously forms a space in which the roller 2b is rotatably disposed. The outer cylinder 2a may include an outer cylinder body 21 fixed inside the first cabinet 1 by an outer cylinder support 23, a front surface 21a of the outer cylinder facing the first front panel 11, a rear surface 21b of the outer cylinder facing the first rear panel 13, and a circumferential surface 21c of the outer cylinder connecting the front and rear surfaces of the outer cylinder body.

[0172] The front surface 21a of the outer cylinder may have an inlet 211 communicating with the interior of the roller 2b, and an installation tube 212 for installing a door 22 for opening and closing the inlet 211. The rear surface 21b of the outer cylinder may have a bearing seat 272 for rotatably fixing the roller shaft 260a to the outer cylinder body 21, a motor 273 fixed to the outer cylinder support 23 and controlled by the first control unit 19, and a power transmission unit for transmitting the power of the motor 273 to the roller shaft 260a.

[0173] The bearing housing 272 can be fixed to the rear surface 21b of the outer cylinder via the drive unit support body 271. The drive unit support body 271 can be configured to include a hub for fixing the bearing housing 272 and a plurality of hub fixing bars arranged radially from the hub.

[0174] The outer cylinder has a rear through hole 21b, and the hub has a hub through hole that connects to the rear through hole. The roller shaft 260a is exposed outside the outer cylinder body 21 through the rear through hole and the hub through hole. The roller shaft 260a exposed outside the outer cylinder body 21 can be rotatably fixed to the hub by the bearing seat 282.

[0175] The outer cylinder body 21 can be fixed to the second support body 235 by the outer cylinder fixing part 238. The outer cylinder fixing part 238 can be configured to include a first strap 238a and a second strap 238b for fixing the outer cylinder circumferential surface 21c to the second support body 235.

[0176] The first strap 238a can be configured to fix the front region of the outer cylinder circumferential surface 21c to the second support body 235, and the second strap 238b can be configured to fix the rear region of the outer cylinder circumferential surface 21c to the second support body 235.

[0177] As the roller 2b rotates, the vibration generated in the roller 2b can be transmitted to the outer cylinder 2a. In order to reduce the vibration transmitted from the roller 2b, the outer cylinder 2a and the second support body 235 may also be provided with an outer cylinder counterweight.

[0178] The outer cylinder counterweight can be configured to include at least one of a first counterweight 239a fixed to the second support body 235 and a second counterweight 239b fixed to the outer cylinder circumferential surface 21c.

[0179] The first counterweight 239a can be fixed to the front of the second support body 235 (see reference). Figure 4 In contrast, the second counterweight 239b can also be fixed to the first strap 238a (see reference). Figure 6 The first counterweight 239a and the second counterweight 239b are both located in the front region of the outer cylinder body 21. This design is made in view of the fact that the drive unit 27 is located in the rear region of the outer cylinder body 21.

[0180] The aforementioned power transmission unit may be configured to include a first pulley 275 fixed to the rotating shaft 274 of the motor, a second pulley 276 fixed to the roller shaft 260a, and a transmission belt 277 connecting the two pulleys.

[0181] Unlike the example shown in the accompanying drawings, the power transmission unit may also consist of a first gear fixed to the rotating shaft 274 of the motor and a second gear fixed to the roller shaft 260a. Furthermore, the power transmission unit may also include a third gear, which connects the first gear and the second gear and sets the rotational speed of the roller body 26 (sets the rotational speed of the second gear).

[0182] As described above, the outer cylinder body 21 is fixed inside the first cabinet 1 by the outer cylinder support 23 and receives water supply through the water supply part 4.

[0183] The water supply unit 4 is a means of guiding water supplied from a water source located outside the garment handling device 100 to the outer drum body 21. The water supply unit 4 may be composed of a flow path that directly connects the water source and the outer drum body 21, or it may be composed of a flow path that supplies detergent and water supplied from the water source to the outer drum body 21 together.

[0184] The aforementioned water supply unit 4 may be configured to include a detergent storage unit 41 forming a space for storing detergent, a storage unit water supply pipe 42 supplying water from the aforementioned water source to the detergent storage unit 41, and a water supply valve 44 controlling the opening and closing of the storage unit water supply pipe 42 according to the control signal from the aforementioned first control unit 19 (see reference). Figure 3 The liquid (water or a mixture of water and detergent) discharged from the detergent storage section 41 is supplied to the outer cylinder supply pipe 46 of the outer cylinder body 21.

[0185] The first processing device 100a may be provided with a connecting part 29 (outer air connecting part) that can discharge the air inside the outer cylinder body 21 to the outside or supply the outside air to the outer cylinder body 21.

[0186] Water may remain in the outer drum body 21 and the drum body 26, but the garment handling device 100 with the above-mentioned connecting part 29 reduces the possibility of water remaining in the outer drum body and the drum body, thereby achieving the effect of hygienic maintenance of the outer drum 2a and the drum 2b.

[0187] Furthermore, even when the door 22 closes the inlet 211, the garment handling device 100 with the connecting portion 29 can prevent the interior of the outer tube body 21 from being sealed. Therefore, the garment handling device 100 can prevent accidents that may occur when the outer tube body 21 is sealed.

[0188] In order to prevent the fluid (water, foam, impurities) inside the outer cylinder body 21 from being discharged to the outside of the first cabinet 1 through the connecting part 29, the first processing device 100a may be provided with a connecting part 5 that connects the flow path formed through the water supply part 4 and the flow path formed through the connecting part 29.

[0189] The aforementioned outer cylinder supply pipe 46 can be fixed in the region above the horizontal line L1 passing through the roller shaft 260a in the rear surface 21b of the outer cylinder. When water is supplied to the interior of the outer cylinder body 21, the pressure in the region above the horizontal line L1 is lower than the pressure in the region below the horizontal line L1 within the interior space of the outer cylinder body 21. Therefore, it is preferable that one end of the outer cylinder supply pipe 46 is fixed at a point higher than the horizontal line L1. When the roller body 26 rotates, vibration may be transmitted to the outer cylinder body 21, so at least a portion of the outer cylinder supply pipe 46 can be constructed of a corrugated pipe.

[0190] The first connecting pipe 291 is fixed in the area above the horizontal line L1 passing through the roller shaft 260a in the rear side 21b of the outer cylinder, thereby connecting the outer cylinder body 21 to the exhaust chamber 515. The second connecting pipe 292 can be configured to connect the drain pipe 281 and the connecting part 5.

[0191] The first connecting pipe 291 is connected to the interior space of the outer cylinder body 21 through the rear side 21b of the outer cylinder, and the second connecting pipe 292 is connected to the drain pipe 281, thereby guiding the water or foam flowing into the exhaust chamber 515 to the drain pipe 281 and discharging it to the outside of the clothing treatment device 100.

[0192] On the other hand, when the air supplied to the outer cylinder body 21 through the outer cylinder air supply section 24 is supplied to the second processing device 100b through the outer cylinder exhaust section 25, a high drying efficiency can be maintained. However, as a clothing processing device 100 provided with the connecting section 29, a portion of the air inside the outer cylinder body 21 can be discharged to the outside through the first connecting pipe 291.

[0193] To reduce the aforementioned phenomena, the flow path cross-sectional area of ​​the first connecting pipe 291 can be set to be smaller than the flow path cross-sectional area of ​​the outer cylinder exhaust section 25. The flow path cross-sectional area of ​​the second connecting pipe 292 can be set to be the same as or smaller than the flow path cross-sectional area of ​​the first connecting pipe 291.

[0194] Figure 7 This is an exploded perspective view showing a second processing apparatus according to an embodiment of the present invention. Figure 8 This is a top view showing the internal structure of a second processing device according to an embodiment of the present invention. Figure 9 This is a split perspective view showing the main components of a second processing apparatus according to an embodiment of the present invention.

[0195] like Figure 7 As shown, the second processing device 100b may be configured to include a second cabinet 6, flow path sections 7 and 8 provided inside the second cabinet 6, and a heat exchange section 9 provided in the flow path section for removing moisture from the air (dehumidification) or heating the air.

[0196] The second cabinet 6 may include a support frame 61 installed on the first cabinet 1, a side panel 65 (second side panel) fixed to the support frame 61 to form the side of the second cabinet, a rear panel 64 (second rear panel) fixed to the support frame 61 to form the rear of the second cabinet, and an upper panel 66 fixed to the support frame 61 to form the upper surface of the second cabinet.

[0197] The aforementioned second side panel 65 may be composed of a left side panel 651 (second left side panel) forming the left side of the aforementioned second cabinet 6 and a right side panel 652 (second right side panel) forming the right side of the aforementioned second cabinet 6.

[0198] The second rear panel 64 may be provided with a panel exhaust port 641 to enable communication between the interior and exterior of the second cabinet 6. Therefore, through the panel exhaust port 641, air inside the second cabinet 6 can be exhausted to the outside, and outside air can flow into the interior of the second cabinet 6.

[0199] A frame panel 62 may be provided on the front side of the aforementioned support frame 61. The frame panel 62 may be configured to form a space for supporting a portion of the aforementioned flow path sections 7 and 8.

[0200] Furthermore, the support frame 61 may be provided with a front panel 67 (second front panel) forming the front of the second cabinet 6. The second front panel 67 may be configured to cover the frame panel 62 to prevent the frame panel 62 from being exposed to the outside. In addition, in order to facilitate user access to the frame panel 62, the second front panel 67 may be rotatably fixed to the support frame 61, the frame panel 62, or the upper panel 66, etc., thereby realizing the opening and closing of the frame panel 62.

[0201] The second front panel 67 can be configured to rotate towards the upper part of the second cabinet 6, and the frame panel 62 can be configured to rotate towards the lower part of the second cabinet 6. That is, the rotation axis of the second front panel 67 can be fixed to the upper region of the upper panel 66 or the upper region of the support frame 61, and the rotation axis of the frame panel 62 can be fixed to the lower region of the support frame 61.

[0202] When the second cabinet 6 is installed on the first cabinet 1, the lower ends of the second side panels 651 and 652 are connected side-by-side to the upper ends of the first side panels 121 and 122 of the first processing device 100a, and the lower end of the second rear panel 64 can be connected side-by-side to the upper end of the first rear panel 13. On the other hand, when the second cabinet 6 is installed on the first cabinet 1, the second front panel 67 can be configured to be located on the same plane as the first front panel 11.

[0203] The front of the support frame 61 can be closed by the frame panel 62, the two sides of the support frame 61 are closed by the second side panels 651 and 652, the upper surface of the support frame 61 is closed by the upper panel 66, and the rear of the support frame 61 is closed by the second rear panel 64.

[0204] The aforementioned frame panel 62 may be configured to include a first through hole 621, a second through hole 622, and a third through hole 623 for enabling communication between the interior and exterior of the aforementioned second cabinet 6.

[0205] In the first through hole 621 of the panel, the first door 624 of the panel is rotatably disposed on the frame panel 62, and in the second through hole 622 of the panel, the second door 626 of the panel can be rotatably disposed on the frame panel 62.

[0206] The first door 624 of the aforementioned panel can be configured as a space for installing a second control unit 63 that controls the second processing device 100b. In this case, the first through hole 621 of the aforementioned panel can become a control unit outlet that exposes the second control unit 63 to the outside of the second cabinet 6.

[0207] The flow path sections 7 and 8 may be provided with filters to filter the air discharged from the outer cylinder body 21, and the second through hole 622 of the panel may be transformed into a filter outlet that leads the filter to the outside of the second cabinet 6.

[0208] The third through hole 623 of the panel can be used as a means of supplying air from outside the second cabinet 6 to the flow path 7 and 8 (panel air supply port).

[0209] A second flow path 8 may be provided on the inner side of the support frame 61. The second flow path 8 is a means of allowing external air to flow into the interior of the second cabinet 6, and can be fixed to the support frame 61 or the second side panels 651, 652.

[0210] The aforementioned second flow path 8 may be located in the left or right area of ​​the front space of the aforementioned second cabinet 6.

[0211] The second cabinet 6 may also be provided with a fixing frame 619 for fixing the second flow path section 8. The fixing frame 619 may be configured to connect the lower frame 611 and the upper frame 617 (to strengthen the support frame), or it may be configured to be fixed to the second side panels 651 and 652 and located in the front space. In this case, the second flow path section 8 may be located in the space formed in the front space between the second side panels 651 and 652, the frame panel 62, and the air supply duct 721 (the corner area of ​​the front space).

[0212] The internal space of the first cabinet 1 is connected to the outside through the installation space 15. In order to connect the internal space of the first cabinet 1 with the internal space of the support frame 61, the bottom surface of the support frame 61 may form a connecting space 612 that communicates with the installation space 15.

[0213] The support frame 61 may be provided with a support panel 613 that divides the communicating space 612 into an open surface and a closed surface. The closed surface may refer to the area in the communicating space 612 where the support panel 613 is located, and the open surface may be defined as the area in the communicating space 612 where the support panel 613 is not located. The communicating space 612 is connected to the mounting space 15, so the mounting space 15 can be considered as also being divided into an open surface and a closed surface by the support panel 613.

[0214] The interior of the aforementioned support frame 61 can be divided into a front space where the aforementioned frame panel 62 is located and a rear space where the aforementioned second rear panel 64 is located. The aforementioned support panel 613 can be fixed to the aforementioned lower frame 611 and is located in the aforementioned rear space.

[0215] The aforementioned front space can be defined as the space located above the aforementioned open surface (the space located above the outer cylinder air supply section 24), and the aforementioned rear space can be defined as the space located above the aforementioned closed surface. The aforementioned frame panel 62 forms one side of the aforementioned front space, and the aforementioned second rear panel 64 forms one side of the aforementioned rear space.

[0216] The aforementioned support panel 613 may be configured as a support body 614 that supports part of the aforementioned flow path section 7, 8 or part of the aforementioned heat exchange section 9, and a fixing body 615 that fixes the aforementioned support body 614 to the aforementioned lower frame 611 (see reference). Figure 9 ).

[0217] The aforementioned support body 614 can be configured to be located at a point lower than the aforementioned lower frame 611. That is, the lowest point of the aforementioned support body 614 can be configured to be located at a point lower than the bottom surface of the aforementioned support frame 61 (the connecting space, the lowest point of the lower frame). When the aforementioned second cabinet 6 is installed on the aforementioned first cabinet 1, the edge of the bottom surface of the aforementioned support frame 61 is supported by the panels 11, 12, and 13 of the first cabinet forming the aforementioned installation space 15, and the aforementioned support body 614 is located inside the aforementioned first cabinet 1. That is, when the aforementioned second cabinet 6 is fixed to the aforementioned first cabinet 1, the aforementioned support body 614 is located at a point lower than the upper end of the aforementioned first side panel 12.

[0218] The aforementioned support panel 613 is configured to support the aforementioned flow path section 7, 8 or heat exchange section 9. Therefore, when the aforementioned support body 614 is configured to be located at a point lower than the aforementioned lower frame 611, it is expected that the overall height of the clothing handling device 100 will be reduced.

[0219] like Figures 8 to 9As shown, the flow path section can be configured to include a first flow path section 7 that is connected to the outer cylinder body 21 to form a circulating flow path for air and a second flow path section 8 that forms a moving path for external air.

[0220] The first flow path section 7 described above may be configured to include an exhaust pipe 71 connected to the exhaust section 25 of the outer cylinder, an air supply pipe 72 connected to the air supply section 24 of the outer cylinder, a heat exchange pipe 73 connected to the exhaust pipe, and an air supply pipe 74 for installing a fan for moving air and connecting the heat exchange pipe 73 and the air supply pipe 72.

[0221] The exhaust pipe 71 may be composed of an exhaust pipe 711 that is detachably fixed to the outer cylinder exhaust section 25 of the first processing device 100a. In order to reduce the transmission of vibration of the outer cylinder body 21 to the heat exchange pipe 73, at least a portion of the exhaust pipe 711 may be provided with an exhaust pipe corrugated section 712.

[0222] The aforementioned air supply duct 72 may be composed of an air supply duct 721, which is fixed to the aforementioned air supply duct 74 to provide a path for the air discharged from the aforementioned air supply duct. In order to reduce the transmission of vibration from the aforementioned outer cylinder body 21 to the aforementioned air supply duct 721, at least a portion of the aforementioned air supply duct 721 or one end of the aforementioned air supply duct 721 may be provided with an air supply duct corrugated section 722.

[0223] The heat exchange pipe 73 can be configured as a heat exchange pipe 73b fixed to the support panel 613. The heat exchange pipe 73b can be configured to include a first heat exchange pipe 734 for mounting a first heat exchanger 91 in the heat exchange section 9, a second heat exchange pipe 735 for mounting a second heat exchanger 92 in the heat exchange section 9, and a connecting pipe 736 connecting the heat exchange pipes 734 and 735.

[0224] The heat exchange pipe 73b can be fixed to the bottom surface (support body) 614 of the support panel 613, and can also be fixed to the flow path placement part 616 provided on the support panel 613. The flow path placement part 616 is a means of maintaining the distance between the bottom surface of the heat exchange pipe 73b and the support body 614 by protruding from the support body 614 toward the heat exchange pipe 73b.

[0225] Air flowing from the outer cylinder body 21 into the first heat exchange pipe 73b through the exhaust pipe 711 condenses upon passing through the first heat exchanger 91, thus potentially leaving condensate inside the heat exchange pipe 73b. To drain the condensate remaining inside the heat exchange pipe 73b, a condensate drain section 75 can be provided in the second processing device 100b. The condensate drain section 75 can be located in the space between the bottom surface of the heat exchange pipe 73b and the support body 614, formed by the flow path placement section 616.

[0226] The aforementioned condensate drain pipe 76 may be configured to include a first condensate drain pipe 761 fixed to the aforementioned support body 614 and connected to the aforementioned first cavity drain pipe 758, and a second condensate drain pipe 762 fixed to the aforementioned support body 614 and connected to the aforementioned second cavity drain pipe 759.

[0227] The aforementioned first condensate drain pipe 761 and second condensate drain pipe 762 are means of guiding condensate to the outside of the aforementioned second cabinet 6. The aforementioned first condensate drain pipe 761 and second condensate drain pipe 762 can be configured to guide condensate to the drain pipe 281 provided in the aforementioned first treatment device 100a.

[0228] The heat exchange pipe 73b can be configured to be directly connected to the exhaust pipe 711, or it can be configured to be connected to the exhaust pipe 711 through a filter flow path 73a. The filter flow path 73a is a space for installing a filter 733 to filter the air supplied to the exhaust pipe 711.

[0229] A filter outlet 731 communicating with the second through hole 622 of the panel can be formed on one side of the filter flow path 73a, and an exhaust pipe connection portion 732 connected to the exhaust pipe 711 is formed on the other side of the filter flow path 73a. As an example, the filter outlet 731 is provided on the front side (facing the frame panel) of the filter flow path 73a, and the exhaust pipe connection portion 732 is provided on the bottom side of the filter flow path 73a.

[0230] The aforementioned air supply duct 74 may be configured to include an air supply duct 74a fixed to the aforementioned support panel 613 and connecting the aforementioned heat exchange duct 73b and the aforementioned air supply duct 721, and an air supply fan (first flow path fan) 74b that moves air along the aforementioned first flow path 7.

[0231] The second flow path section 8 may be configured to include a first external air duct 82 located inside the second cabinet 6 and into which external air flows, a second external air duct 83 connected to the first external air duct 82 and having a third heat exchanger 93 located in the heat exchange section 9, and a second flow path fan 84 for moving air.

[0232] The first external air duct 82 is configured to connect to the panel air supply port 623 provided on the frame panel 62. The first external air duct 83 is configured to extend along the length direction (X-axis direction) of the second cabinet.

[0233] The aforementioned second external air duct 83 can be configured as a flow path extending along the height direction (Z-axis direction) of the aforementioned second cabinet. The aforementioned second external air duct 83 is configured to extend along the height direction of the aforementioned second cabinet 6, and the aforementioned second flow path fan 84 is provided in the aforementioned second external air duct 83 in order to reduce the possibility of the aforementioned second flow path fan 84 overheating.

[0234] When the second processing device 100b is operating, heated air is supplied to the outer cylinder body 21, causing the temperature of the circumferential surface of the outer cylinder body 21 to rise. The second flow path 8 is located on the upper part of the outer cylinder body 21; therefore, if the second flow path fan 84 is close to the outer cylinder body 21, overheating may occur due to the heat released to the outside of the outer cylinder body 21. However, by configuring the second flow path 8 as described above, the possibility of overheating of the second flow path fan 84 can be significantly reduced.

[0235] On the other hand, the aforementioned external air supply port 81 can also be formed on the upper surface, the side surface, or the lower surface of the second front panel 67. It should be noted that when the aforementioned external air supply port 81 is formed on the upper surface of the second front panel 67, it is advantageous to supply external air to the second flow path section 8.

[0236] The heat exchange section 9 may be configured to include the first heat exchanger 91 provided in the first heat exchange pipe 734 to remove moisture from the air, the second heat exchanger 92 provided in the second heat exchange pipe 735 to heat the air, the third heat exchanger 93 provided in the second flow path section 8 to exchange heat with the outside air, the refrigerant pipe 96 forming a circulation path for the refrigerant through the heat exchangers 91, 92, and 93, and the compressor 94 moving the refrigerant along the refrigerant pipe.

[0237] On the other hand, the second flow path 8 can be located in the left-side region of the front space, and the compressor 94 and the heat exchangers 91 and 92 can be located in the right-side region of the rear space. Alternatively, the second flow path 8 can be located in the corner region of the front space formed by the frame panel 62 and the second left-side panel 651, and the compressor 94 can be located in the corner region of the rear space formed by the second right-side panel 652 and the second rear panel 64.

[0238] To create a space for mounting the compressor 94 in the corner area of ​​the aforementioned rear space, the first heat exchange pipe 734 and the second heat exchange pipe 735 can be connected at a predetermined angle. Specifically, the connecting pipe 736 can be inclined at an angle greater than 0 degrees and less than 90 degrees relative to a straight line parallel to the second heat exchange pipe 735, thereby connecting the first heat exchange pipe 734 and the second heat exchange pipe 735. In this case, the compressor 94 can be fixed to the support panel 613 and located between the connecting pipe 736 and the corner of the rear space.

[0239] In order to facilitate the combination of the second processing device 100b with or from the first processing device 100a, it can be configured such that at least one of the free end of the exhaust pipe 711 (the part with the exhaust pipe corrugation) and the free end of the air supply pipe 721 (the part with the air supply pipe corrugation) is located on the open surface of the communicating space 612.

[0240] Furthermore, the aforementioned outer cylinder air supply section 24 and the aforementioned outer cylinder exhaust section 25 can be configured to be located below the aforementioned open surface. Moreover, the aforementioned outer cylinder air supply section 24 can be configured to protrude from the aforementioned mounting pipe 212 toward the aforementioned open surface, and the aforementioned outer cylinder exhaust section 25 can protrude from the circumferential surface 21c of the aforementioned outer cylinder body toward the aforementioned open surface (see reference). Figure 10 ).

[0241] To facilitate the integration of the second processing device 100b with or removal from the first processing device 100a, it can be configured such that at least one of the free end (the part connected to the air supply pipe) of the outer cylinder air supply section 24 and the free end (the part connected to the exhaust pipe) of the outer cylinder exhaust section 25 is located at a point higher than the upper end of the first cabinet 1.

[0242] Figure 10 This is a simplified diagram illustrating the combination of a first processing device and a second processing device according to an embodiment of the present invention.

[0243] Figure 10 This is a diagram illustrating, as an example, that the free end (the part for connecting the air supply pipe) of the aforementioned outer cylinder air supply section 24 is located at a point higher than the upper end of the aforementioned first cabinet 1.

[0244] When the upper end of the first front panel 11 or the upper end of the first rear panel 13 is configured to be located at a point H1 that is higher than the upper ends of the first side panels 121 and 122, the free end of the outer cylinder air supply section 24 can be configured to be located at a point that is higher than the upper end of the first front panel 11 or the upper end of the first rear panel 13.

[0245] On the other hand, as described above, the bottom surface (support body) 614 of the support panel 613 is configured to be located at a point H2 that is lower than the lowest end of the support frame 61. The heat exchange pipe 73 and the air supply pipe 74 are fixed to the bottom surface of the support panel 613. Therefore, the present invention can reduce the overall height of the clothing processing device 100.

[0246] The main components of the present invention, namely the roller 2b described above, will now be described in detail with reference to the accompanying drawings.

[0247] A split perspective view of the roller of the first processing device according to an embodiment of the present invention. Figure 12 This is a cross-sectional perspective view showing the internal structure of a drum according to an embodiment of the present invention. Figure 13 This is a cross-sectional view showing a roller and a weighing instrument fastened to the roller according to an embodiment of the present invention.

[0248] The roller 2b described above can be formed into a cylindrical shape with an internal processing space for receiving the object to be processed and an open front. This roller 2b may include a front roller plate 26b forming the front side of the roller 2b, a rear roller plate 26c forming the rear side of the roller 2b, a roller body 26a connecting the front roller plate 26b and the rear roller plate 26c to form the space for the object to be processed, and a reinforcing plate 26d attached to the outside of the rear roller plate 26c to strengthen the rear roller plate 26c.

[0249] Inside the roller 2b, a separate fastening bolt 261e may be provided on the inner side of the roller body 26a, penetrating the front roller plate 26b and the rear roller plate 26c to fix the front roller plate 26b and the rear roller plate 26c, so that the material to be processed inside the roller 2b flows with the rotation of the roller 2b. The fastening bolt 261e may be located inside the lifting member 26e.

[0250] A pair of balancers 26f may be provided on the outer side of the front and rear of the aforementioned roller 2b. Specifically, a front balancer 26f is provided on the outer side of the aforementioned front roller plate 26b to compensate for the imbalance caused by the object to be processed when the aforementioned roller 2b rotates, and a rear balancer 26f is provided on the outer side of the aforementioned rear roller plate 26c to compensate for the imbalance caused by the object to be processed when the aforementioned roller 2b rotates.

[0251] Among them, the aforementioned front balancer 26f and the aforementioned rear balancer 26f are balancers with the same structure, symmetrically arranged on the aforementioned front roller plate 26b and the aforementioned rear roller plate 26c respectively.

[0252] Therefore, the aforementioned front balancer 26f and rear balancer 26f can be formed with the same structure, only differing in their orientation when installed on the front roller plate 26b and rear roller plate 26c. In this invention, for ease of explanation, the description is divided into the aforementioned front balancer 26f and rear balancer 26f; this is merely to indicate the name of the location of the balancer 26f.

[0253] The front balancer 26f and the rear balancer 26f will be described in detail again after the description of the roller 2b is concluded.

[0254] The outer circumferential surface of the roller 2b, which forms a cylindrical shape, is typically formed by stamping or deep drawing of a metal sheet of predetermined thickness. The following description is based on the state in which the roller body 26a is formed into a cylindrical shape.

[0255] Multiple holes may be formed on the entire front side of the roller body 26a for draining water contained in the material to be treated and placed inside the roller 2b. Additionally, multiple balancer fastening holes 264a and 266a may be formed at the corner portions of the roller body 26a corresponding to the front and rear directions of the roller 2b for securing the front balancer 26f and the rear balancer 26f. Furthermore, the roller body 26a may have multiple lifting member fastening holes 261a and lifting member mounting holes 261a' for securing the lifting member 26e to the roller body 26a.

[0256] As described above, the roller body 26a can be formed with multiple holes for performing various functions, and these holes can be repeatedly formed at certain intervals in the roller body 26a.

[0257] On the other hand, the aforementioned roller body 26a is formed into a cylindrical shape with an open front and rear by deep drawing, and the two ends of the roller body 26a can be formed into a cylindrical shape by rolling or welding. The manufacturing process of this roller body 26a will be described in detail with reference to the other accompanying drawings after the description of the roller 2b is completed.

[0258] On the other hand, a front rolled portion 262a, which bends toward the front outer peripheral surface of the roller 2b and is joined to the front roller plate 26b by rolling, can be formed at the front of the roller body 26a, which is formed into a cylindrical shape. A rear rolled portion 265a, which bends toward the rear outer peripheral surface of the roller 2b and is joined to the rear roller plate 26c by rolling, is formed at the rear of the roller body 26a.

[0259] The aforementioned front curled portion 262a of the cylinder can be curled and combined with the front plate curled portion 263b of the front roller plate 26b described later. In this case, the front curled portion 262a of the cylinder is formed with a width smaller than the front plate curled portion 263b, so that the front plate curled portion 263b can be curled and combined in a manner that curls outward toward the outside of the roller 2b while wrapping around the front curled portion 262a of the cylinder.

[0260] The aforementioned rear curled portion 265a of the cylinder can be curled and joined with the rear plate curled portion 263c of the rear roller plate 26c described later. In this case, the rear curled portion 265a of the cylinder is formed with a width smaller than the rear plate curled portion 263c, so that the rear plate curled portion 263c can be curled and joined in a manner that curls outwards towards the outside of the roller 2b while simultaneously wrapping around the rear curled portion 265a of the cylinder (see reference). Figure 13 ).

[0261] A front balancer fastening hole 264a for fixing the front balancer 26f is formed in the front curled portion 262a of the cylinder, and a rear balancer fastening hole 266a for fixing the rear balancer 26f is formed in the rear curled portion 265a of the cylinder.

[0262] Different fastening components pass through the aforementioned front balancer fastening hole 264a and rear balancer fastening hole 266a, respectively, so as to fix the aforementioned front balancer 26f and rear balancer 26f.

[0263] The aforementioned front balancer fastening hole 264a and rear balancer fastening hole 266a of the cylinder can be configured to communicate with the front balancer fastening hole 264b of the front roller plate 26b and the rear balancer fastening hole 264c of the rear roller plate 26c, respectively.

[0264] That is, the aforementioned front balancer 26f can be fixed by fastening components that pass through the aforementioned front balancer fastening holes 264a and 264b of the cylinder, and the aforementioned rear balancer 26f can be fixed by fastening components that pass through the aforementioned rear balancer fastening holes 266a and 264c of the cylinder.

[0265] Multiple lifting members 26e may be provided on the inner side of the roller body 26a to enhance the movement of the workpiece fed into the roller 2b when the roller 2b rotates. The lifting members 26e can be fixed in position by being substantially inserted into the lifting member fastening hole 261a formed in the roller body 26a, and can be fixed by a lifting member setting hole 261a' adjacent to the lifting member fastening hole 261a. The lifting members 26e can be fixed to the inner wall of the roller body 26a by a separate fastening component (not shown) that penetrates the lifting member fastening hole 261a on the outside of the roller 2b.

[0266] Additionally, a fastening bolt 261e, penetrating the front roller plate 26b and the rear roller plate 26c, may be provided inside the lifting member 26e. To fasten the front roller plate 26b and the rear roller plate 26c using the fastening bolt 261e, a front bolt fastening hole 267b and a rear bolt fastening hole 267c may be formed in the front roller plate 26b and the rear roller plate 26c, respectively, corresponding to the formation position of the lifting member 26e.

[0267] The aforementioned fastening bolt 261e passes through the aforementioned front bolt fastening hole 267b formed in the aforementioned front roller plate 26b and the aforementioned rear bolt fastening hole 267c formed in the aforementioned rear roller plate 26c, and is then fixed on the outside of the aforementioned front roller plate 26b and the aforementioned rear roller plate 26c by other fastening nuts 262e.

[0268] That is, the roller body 26a can be fastened by the additional bonding force provided by the fastening bolts 261e that pass through the front roller plate 26b and the rear roller plate 26c. In addition, the fastening bolts 261e can be formed inside the lifting member 26e provided on the inner circumferential surface of the roller 2b, and the lifting member 26e can shield the outside (i.e., the inside of the roller 2b).

[0269] The aforementioned front roller plate 26b is formed in an annular shape with a roller inlet 261b in the center for inserting the workpiece. A front inclined surface 262b is formed on the inner side adjacent to the roller inlet 261b, protruding toward the outer cylinder inlet 211 of the outer cylinder 2a. Through the aforementioned front inclined surface 262b, the outer cylinder inlet 211 and the roller inlet 261b can be formed to be relatively adjacent.

[0270] The outer peripheral surface of the aforementioned front roller plate 26b has a front plate curled portion 263b that is coupled to the front side of the aforementioned roller body 26a. The aforementioned front plate curled portion 263b is formed to bend from the outer peripheral surface of the aforementioned front roller plate 26b toward the front side of the aforementioned roller 2b, and the outer peripheral surface of the aforementioned front plate curled portion 263b can be formed to be in close contact with the inner peripheral surface of the aforementioned main body front curled portion 262a of the aforementioned roller body 26a.

[0271] A front balancer placement surface 266b is formed between the front inclined surface 262b and the front plate curled portion 263b of the aforementioned front roller plate 26b, forming a space for mounting the aforementioned front balancer 26f. The aforementioned front balancer placement surface 266b may have a front balancer fastening groove 265b, and the fastening portion 266f formed on the aforementioned front balancer 26f is placed in the front balancer fastening groove 265b.

[0272] At a position corresponding to the fastening portion 266f formed on the aforementioned front balancer 26f (described later), a plurality of the aforementioned front balancer fastening placement grooves 265b can be formed. By placing the aforementioned fastening portion 266f of the aforementioned front balancer 26f in the aforementioned front balancer fastening placement grooves 265b, the fastening position of the aforementioned front balancer 26f can be determined.

[0273] The aforementioned front balancer fastening placement groove 265b and the aforementioned front balancer fastening part 266f can be arranged at a certain angle with the center of the aforementioned front balancer 26f as a reference. The arrangement of the aforementioned front balancer fastening placement groove 265b and the aforementioned fastening part 266f will be described in detail in the description of the manufacture of the aforementioned roller body 26a.

[0274] A front balancer fastening hole 264b can be formed in the aforementioned front plate curling portion 263b for inserting and engaging other fastening components (not shown) into the aforementioned fastening portion 266f of the aforementioned front balancer 26f.

[0275] The aforementioned front balancer fastening hole 264b can be formed at the same position as the cylinder front balancer fastening hole 264a formed in the cylinder front curling portion 262a of the roller body 26a. Other fastening components pass through the cylinder front balancer fastening hole 264a of the cylinder front curling portion 262a and the front balancer fastening hole 264b of the front plate curling portion 263b, so that the aforementioned front balancer 26f can be fixed to the front of the roller 2b.

[0276] The aforementioned rear roller plate 26c is formed in the shape of a disc with a roller shaft fastening portion 162c formed in the center to fasten the roller shaft 260a. Between the outer peripheral surface of the rear roller plate 26c and the roller shaft fastening portion 162c, a rear inclined surface 262c protruding from the center of the rear roller plate 26c toward the inside of the roller 2b is formed. That is, the roller fastening portion 266f used to fasten the roller shaft 260a can be substantially located inside the roller 2b.

[0277] The aforementioned rear inclined surface 262c is a component used to enable the rear roller plate 26c to form a predetermined strength as the rear roller plate 26c and the reinforcing plate 26d are fastened.

[0278] The aforementioned rear roller plate 26c has a rear plate curled portion 263c formed on its outer peripheral surface, which is coupled to the rear side of the aforementioned roller body 26a. The aforementioned rear plate curled portion 263c is formed to bend from the outer peripheral surface of the aforementioned rear roller plate 26c toward the rear side of the aforementioned roller 2b, and the outer peripheral surface of the aforementioned rear plate curled portion 263c can be formed to be in close contact with the inner peripheral surface of the aforementioned main body rear curled portion 265a of the aforementioned roller body 26a.

[0279] Therefore, the rear plate curled portion 263c of the rear roller plate 26c and the rear cylinder curled portion 265a of the roller body 26a curl outward toward the outside of the roller 2b, so that the rear roller plate 26c and the rear of the roller body 26a can be joined (see reference). Figure 15 ).

[0280] Between the rear inclined surface 262c and the rear plate curled portion 263c of the rear roller plate 26c, a rear balancer placement surface 266c is formed, creating a space for mounting the rear balancer 26f. The rear balancer placement surface 266c may have a rear balancer fastening groove 265c, and the fastening portion 266f formed on the rear balancer 26f is placed in the rear balancer fastening groove 265c.

[0281] At a position corresponding to the fastening portion 266f formed on the rear balancer 26f as described later, a plurality of rear balancer fastening placement slots 265c can be formed. By placing the fastening portion 266f of the rear balancer 26f in the rear balancer fastening placement slots 265c, the fastening position of the rear balancer 26f can be determined.

[0282] The rear balancer fastening groove 265c and the fastening part 266f of the rear balancer can be arranged at a certain angle with the center of the rear balancer 26f as a reference. The arrangement of the rear balancer fastening groove 265c and the fastening part 266f will be explained in detail in the description of the manufacture of the roller body 26a.

[0283] The aforementioned rear plate curled portion 263c may have a rear balancer fastening hole 264c for inserting and engaging other fastening components (not shown) into the aforementioned fastening portion 266f of the rear balancer 26f.

[0284] The aforementioned rear balancer fastening hole 264c can be formed at the same position as the rear balancer fastening hole 266a of the rear coiled portion 265a of the roller body 26a. Other fastening components pass through the rear balancer fastening hole 266a of the rear coiled portion 265a and the rear balancer fastening hole 264c of the rear plate coiled portion 263c, so that the rear balancer 26f can be fixed behind the roller 2b.

[0285] The aforementioned reinforcing plate 26d can be fixed to the back of the rear roller plate 26c, thereby strengthening the rear roller plate 26c. Specifically, the rear roller plate 26c is connected to the roller shaft 260a for rotating the roller 2b. Since the roller 2b contains materials to be processed, a relatively large load may be applied between the rear roller plate 26c and the roller shaft 260a. Therefore, it is necessary to strengthen the rear roller plate 26c, which is connected to the roller shaft 260a.

[0286] The aforementioned reinforcing plate 26d can be formed as a disc of predetermined thickness, with a roller shaft hole 262d for inserting the aforementioned roller shaft 260a formed in its central portion. The aforementioned reinforcing plate 26d can be formed using a sheet material that is thicker than the aforementioned rear roller plate 26c.

[0287] By forming a right-angled triangle shape with respect to the roller shaft 260a as a reference, the cross-sectional shape of the reinforcing plate 26d attached to the rear roller plate 26c is formed, thereby strengthening the relationship between the reinforcing plate 26d and the roller shaft 260a connected to the rear roller plate 26c.

[0288] The outer peripheral surface of the reinforcing plate 26d can be located inside the rear balancer placement surface 266c. That is, the outer peripheral surface of the reinforcing plate 26d can have a diameter that is larger than the rear inclined surface 262c formed on the rear roller plate 26c and smaller than the rear balancer placement surface 266c.

[0289] The outer peripheral surface of the reinforcing plate 26d may have a welding surface 261d for welding to the rear balancer placement surface 266c. That is, the outer peripheral surface of the reinforcing plate 26d can be fixed to the rear balancer placement surface 266c by welding.

[0290] On the other hand, the outer peripheral surface of the aforementioned reinforcing plate 26d can also be fastened to the aforementioned rear roller plate 26c by welding. That is, in the existing roller 2b, the roller body 26a, the front roller plate 26b, and the rear roller plate 26c are integrated through a separate welding process. However, when manufacturing the roller 2b using a welding process, it is necessary to deal with welding heat deformation and the formation of the welding parts. In addition, when manufacturing the roller 2b using a welding process, the desired size and strength may be reduced due to the heat deformation of the material caused by welding.

[0291] On the other hand, in commercial washing machines, the loading of the items to be processed into the aforementioned drum 2b is relatively large. In this case, maintaining the rigidity of the aforementioned drum 2b is one of the most important design objectives.

[0292] In particular, when the rigidity of the front and rear of the aforementioned roller 2b decreases, an imbalance caused by the work to be processed may occur when the roller 2b rotates during the drying process, which may lead to deformation of the roller 2b or the roller 2b itself may exert an impact on the interior of the outer cylinder 2a.

[0293] Therefore, as described above, when fastening the roller body 26a, the front roller plate 26b, and the rear roller plate 26c, no other welding process is performed. The two ends of the roller body 26a are fastened to the front roller plate 26b and the rear roller plate 26c by the rolling process, thereby preventing possible shape deformation and strength reduction due to welding points.

[0294] The front balancer 26f and the rear balancer 26f described above will now be described in detail with reference to the accompanying drawings. On the other hand, as described above, the front balancer 26f and the rear balancer 26f of the present invention are balancers with the same structure but arranged in different fastening directions in front of and behind the roller. That is, the front balancer 26f and the rear balancer 26f are formed with the same shape, but can be divided into the front balancer 26f and the rear balancer 26f depending on the installation position of the roller.

[0295] Therefore, for ease of explanation, the aforementioned front balancer 26f and the aforementioned rear balancer 26f will be collectively referred to as a single balancer in the following description.

[0296] Figure 14 This is a rear view showing the back of a balancer according to an embodiment of the present invention. Figure 15 This is a front view showing the front of a balancer according to an embodiment of the present invention. Figure 18 This is a split cross-sectional view showing the balancer before tightening according to an embodiment of the present invention.

[0297] like Figures 14 to 18 As shown, the balancer 26f forms an annular moving space inside for the movement of the balancer balls (not shown). Other fluids (not shown) and the balancer balls are inserted, so that as the roller 2b rotates, the movement of the balancer balls alleviates the imbalance of the roller 2b.

[0298] The aforementioned balancer 26f can be divided into an inner body 264f facing the roller 2b and an outer body 261f facing the roller 2b. By ultrasonic welding, the inner body 264f and the outer body 261f can be welded together to form the movement space for the balancer balls and the fluid.

[0299] On the other hand, the inner body 264f and the outer body 261f can be manufactured by injection molding using synthetic resin. After injection molding, the inner body 264f and the outer body 261f are welded together by ultrasonic welding, thereby forming a moving space for the balancer ball to move.

[0300] During the injection molding of the inner body 264f and the outer body 261f, the thickness of each part of the body is uneven. Due to this uneven thickness, shrinkage occurs during cooling after injection molding of the inner body 264f and the outer body 261f, which is caused by the synthetic resin material and thickness. Therefore, after injection molding of the inner body 264f and the outer body 261f, the roundness and flatness of the inner body 264f and the outer body 261f may be uneven.

[0301] The inner body 264f and the outer body 261f are fused together to form a ring with a space in the center. The inner body 264f can be fastened to the roller in a manner that faces the front roller plate 26b or the rear roller plate 26c.

[0302] like Figure 14 as well as Figure 18 As shown, the inner body 264f includes an inner body portion 264f' formed in an annular shape. On the side of the outer body 261f facing the inner body portion 264f', an inner moving groove 265f for forming a moving space for the balancer ball and the fluid is formed along the center of the annular inner body portion 264f'.

[0303] On the other hand, the aforementioned inner main body 264f' may form an outer side wall 264fa and an inner side wall 264fb. When forming the aforementioned inner moving groove 265f, the outer side wall 264fa forms the outer side surface of the aforementioned inner main body 264f' and simultaneously forms one side wall of the aforementioned inner moving groove 265f. The aforementioned inner side wall 264fb forms the inner side surface of the aforementioned inner main body 264f' and simultaneously forms the other side wall of the aforementioned inner moving groove 265f.

[0304] The thickness T1 of the inner wall 264fb can be made thicker than the thickness T2 of the outer wall 264fa. The inner wall 264fb can be formed with an inner support protrusion 2651f, which can be supported by the welding device.

[0305] Therefore, given that the inner support protrusion 2651f is supported by the welding device (not shown), the thickness T1 of the inner wall 264fb is formed to be thicker than the thickness T2 of the outer wall 264fa, thereby enhancing the strength.

[0306] On the other hand, when the thickness T1 of the inner sidewall 264fb is made thicker than the thickness T2 of the outer sidewall 264fa, during the injection molding of the inner body 264f, shrinkage deformation may occur in the inner sidewall 264fb depending on the cooling time of the inner sidewall 264fb and the outer sidewall 264fa. This shrinkage deformation of the inner sidewall 264fb may cause deformation of the overall roundness and flatness of the inner body 264f.

[0307] On the other hand, in order to minimize the shrinkage deformation as described above, a space 264fe can be formed inside the inner sidewall 264fb. For this purpose, the inner sidewall 264fb can include a first inner sidewall 264fc for forming the other sidewall of the inner moving groove 265f, and a second inner sidewall 264fd extending from and separate from the first inner sidewall 264fc. The space 264fe is formed between the first inner sidewall 264fc and the second inner sidewall 264fd, and the first inner sidewall 264fc, the second inner sidewall 264fd, and the outer sidewall 264fa can be formed with relatively similar thicknesses. Therefore, it is possible to minimize the shrinkage deformation occurring in the inner sidewall 264fb and the outer sidewall 264fa, which are composed of the first inner sidewall 264fc and the second inner sidewall 264fd.

[0308] Furthermore, the space 264fe formed between the first inner sidewall 264fc and the second inner sidewall 264fd may also be provided with a reinforcing rib 264ff to strengthen the bond between the first inner sidewall 264fc and the second inner sidewall 264fd. Preferably, the reinforcing rib 264ff is also formed to have a similar thickness to the first inner sidewall 264fc and the second inner sidewall 264fd. In this case, it is possible to minimize the shrinkage deformation that may occur in the first inner sidewall 264fc, the second inner sidewall 264fd, and the reinforcing rib 264ff.

[0309] On the outer edge (i.e., the end of the outer wall 264fa, hereinafter referred to as "the outer edge of the inner moving groove 265f") and the inner edge (i.e., the end of the inner wall 264fb, hereinafter referred to as "the inner edge of the inner moving groove 265f") of the aforementioned inner moving groove 265f, along the forming direction of the aforementioned inner moving groove 265f, a plurality of inner welding grooves 2641f~2645f and a plurality of inner welding protrusions 2646f~2648f for welding with the aforementioned outer body 261f can be formed in an annular shape.

[0310] On the other hand, on the outer edge of the aforementioned inner moving groove 265f, along the direction from the outer edge of the aforementioned inner moving groove 265f toward the inner edge, a first inner welding groove 2641f, a first inner welding protrusion 2646f, and a second inner welding groove 2642f are sequentially formed.

[0311] The first inner weld groove 2641f and the second inner weld groove 2642f are formed to be deeper than the lower part of the first inner weld protrusion 2646f, and the upper end of the first inner weld protrusion 2646f can be formed to be higher than the upper end of the first inner weld groove 2641f and the second inner weld groove 2642f.

[0312] Along the inner edge of the aforementioned inner moving groove 265f, a third inner welding groove 2643f, a second inner welding protrusion 2632f, a fourth inner welding groove 2644f, a third inner welding protrusion 2648f, and a fifth inner welding groove 2645f are sequentially formed in the direction from the outer edge of the aforementioned inner moving groove 265f toward the inner edge.

[0313] The second inner welding protrusion 2647f and the third inner welding protrusion 2648f have the same shape and are configured to form the fourth inner welding groove 2644f in the middle. The third inner welding groove 2643f and the fifth inner welding groove 2645f are formed to be deeper than the fourth inner welding groove 2644f.

[0314] The aforementioned second inner welding protrusion 2647f and the aforementioned third inner welding protrusion 2648f can be formed to be higher than the upper ends of the aforementioned third inner welding groove 2643f and the fifth inner welding groove 2645f.

[0315] The plurality of inner welding grooves 2641f~2645f and the plurality of inner welding protrusions 2646f~2648f formed on the aforementioned inner main body portion 264f' can be cross-welded with the plurality of outer welding grooves 2636f~2638f and the plurality of outer welding protrusions 2631f~2635f formed on the aforementioned outer main body portion 261f' as described later.

[0316] The configuration of the plurality of inner weld grooves 2641f to 2645f and the plurality of inner weld protrusions 2646f to 2648f formed on the inner body portion 264f' will be described in detail after the description of the outer body portion 261f.

[0317] On the inner circumferential surface of the inner body 264f (i.e., the inner surface facing the center of the balancer 26f), an inner support protrusion 2651f is continuously arranged along the inner circumferential surface of the inner body 264f. When ultrasonic welding is performed with the support of the welding device described later, the inner support protrusion 2651f is supported by the welding device.

[0318] The aforementioned inner support protrusion 2651f may be formed on the inner peripheral surface of the inner wall 264fb of the inner main body 264f' or on the inner peripheral surface of the second inner wall 264fd that forms the inner wall 264fb. In the following description, for ease of explanation, it will be assumed that the inner support protrusion 2651f is formed on the inner peripheral surface of the inner main body 264f. However, this is not a limitation on the position of the inner support protrusion 2651f; it may be formed at any point where the inner peripheral surface of the inner main body 264f is formed, extending in a direction toward the center of the inner main body 264f.

[0319] The aforementioned inner support protrusion 2651f can protrude from the aforementioned inner main body portion 264f' toward the center of the aforementioned balancer 26f, and can be formed with an inner diameter smaller than the inner diameter of the aforementioned inner main body portion 264f'. Each of the aforementioned inner support protrusions 2651f can be formed with an arcuate shape having the same center as the center of the aforementioned inner main body portion 264f.

[0320] On the other hand, the aforementioned inner support protrusion 2651f may be formed on the inner peripheral surface of the inner body 264f, or on the inner peripheral surface of the inner body portion 264f' used to form the inner peripheral surface of the inner body 264f, or on the inner wall 264fb used to form the inner body portion 264f', or on the second inner wall 264fd used to form the inner wall 264fb.

[0321] The aforementioned inner support protrusion 2651f can be selectively formed in one of the configurations used to form the inner peripheral surface of the inner body 264f. In this invention, for ease of explanation, it is described as being formed on the inner peripheral surface of the inner body 264f. However, this is not a limitation on the formation position of the inner support protrusion 2651f, and it can be formed in any configuration used to form the inner peripheral surface of the inner body 264f.

[0322] On the other hand, the welding apparatus for ultrasonic welding of the inner body 264f and the outer body 261f includes an inner body guide G2 that supports the inner support protrusion 2651f of the inner body 264f (see reference). Figure 20 The inner body guide G2 supports the inner body 264f after the inner support protrusion 2651f is concentric with the center of the inner body 264f.

[0323] Figures 18 to 19 As shown, the inner support protrusion 2651f protrudes from the inner circumferential surface of the inner body. The upper surface of the inner support protrusion 2651f may be formed with an upper inclined surface 2651fa that slopes downward toward the inner body guide G2 so that pressure is applied toward the placement part (not shown) of the welding device supporting the inner body 264f when the inner body guide G2 is tightened.

[0324] In addition, the lower part of the aforementioned inner support protrusion 2651f may also be formed with a lower inclined surface 2654fa that slopes upward toward the inner main body guide G2, so that the aforementioned inner support protrusion 2651f can be easily inserted into the aforementioned inner main body guide G2 of the welding device.

[0325] This inner support protrusion 2651f can be integrally formed on the inner circumferential surface of the inner body 264f. However, the inner body 264f can be injection molded from synthetic resin, and the volume of the inner support protrusion 2651f can be relatively larger than the inner circumferential surface of the inner body 264f on which the inner support protrusion 2651f is formed.

[0326] When the volume of the inner support protrusion 2651f is relatively larger than the inner circumferential surface of the inner body 264f on which the inner support protrusion 2651f is formed, the cooling of the inner support protrusion 2651f is slower during the injection molding of the inner body 264f. As a result, shrinkage deformation may occur in the inner support protrusion 2651f. If shrinkage deformation occurs in the inner support protrusion 2651f, it may not be able to be supported in the normal position when supported by the inner body guide G2.

[0327] Therefore, the aforementioned inner support protrusion 2651f can be formed into a plate-like rib shape extending from the inner peripheral surface of the aforementioned inner body 264f. The rib-shaped inner support protrusion 2651f can extend downward at an incline from the inner peripheral surface of the aforementioned inner body 264f toward the center of the aforementioned inner body 264f, and the upper surface of the rib-shaped inner support protrusion 2651f can form the aforementioned upper inclined surface 2651fa.

[0328] Furthermore, a support rib 2654f for supporting the inner support protrusion 2651f may be formed at the lower part of the rib-shaped inner support protrusion 2651f. The inner support protrusion 2651f of the rib shape may be formed at certain intervals along the inner circumferential surface of the inner body 264f, thereby extending a certain length.

[0329] When the inner support protrusion 2651f is formed in a rib shape, deformation of the inner support protrusion 2651f may occur when supported by the inner main body guide G2. To prevent deformation of the inner support protrusion 2651f, the support rib 2654f can be formed between the inner circumferential surface of the inner main body 264f and the lower part of the rib-shaped inner support protrusion 2651f, thereby supporting the inner support protrusion 2651f. Multiple support ribs 2654f are formed at certain intervals on the inner circumferential surface of the inner main body 264f and at the lower part of the inner support protrusion 2651f.

[0330] On the other hand, the inner support protrusion 2651f and the support rib 2654f with the rib shape are structures that provide support for the inner main body guide G2. In order to have a certain strength or above, they preferably have a certain thickness or above.

[0331] However, when the thickness of the inner support protrusion 2651f and the support rib 2654f is too thick, shrinkage deformation due to cooling may occur in the inner support protrusion 2651f and the support rib 2654f during the injection molding of the inner body 264f.

[0332] To prevent shrinkage deformation during injection molding, the rib-shaped inner support protrusion 2651f can have a thickness of 1 mm to 2 mm. Specifically, preferably, the rib-shaped inner support protrusion 2651f is formed to have a thickness of 1.5 mm. This thickness of the inner support protrusion 2651f can prevent shrinkage deformation caused by cooling of the inner support protrusion 2651f.

[0333] Furthermore, similar to the inner support protrusion 2651f with a rib shape, the support rib 2654f may have a thickness of 1 mm to 2 mm to prevent shrinkage deformation during injection molding. Specifically, preferably, the support rib 2654f is formed to a thickness of 1.5 mm. This thickness of the support rib 2654f can prevent shrinkage deformation caused by cooling of the support rib 2654f.

[0334] Furthermore, the aforementioned support rib 2654f can be formed such that its thickness gradually decreases as it approaches the center of the inner body 264f. Specifically, the aforementioned support rib 2654f can have a thickness of 1.5 mm on the inner circumferential surface of the inner body 264f, and its thickness decreases to 1 mm as it approaches the end of the aforementioned support rib 2654f.

[0335] The lower part of the aforementioned support rib 2654f may have the aforementioned lower inclined surface 2654fa. The lower inclined surface 2654fa formed on the aforementioned support rib 2654f makes it easy for the aforementioned inner support protrusion 2651f to be inserted into the aforementioned inner main body guide G2 of the aforementioned welding device.

[0336] Multiple fastening parts 266f can be protruding from the inner body 264f facing the roller 2b, at positions corresponding to the front balancer fastening groove 265b of the front roller plate 26b and the rear balancer fastening groove 265c of the rear roller plate 26c.

[0337] The outer surface of the fastening portion 266f (i.e., the direction toward the outer peripheral surface of the balancer 26f) may be formed with fastening holes for fixing the balancer 26f to the roller body 26a. These fastening holes can be secured by inserting other fastening components that pass through the balancer fastening holes 264a and 266a formed in the front curled portion 262a and the rear curled portion 265a of the roller body 26a.

[0338] One side of the fastening part 266f (i.e., the side facing the front balancer fastening groove 265b or the rear balancer fastening groove 265c) may also be provided with a support protrusion 267f, which is inserted into the inner side of the front balancer fastening groove 265b or the rear balancer fastening groove 265c to support the inner surface of the front balancer fastening groove 265b or the rear balancer fastening groove 265c.

[0339] By maintaining the distance between the front balancer fastening slot 265b or the rear balancer fastening slot 265c and the fastening part 266f at a certain level, the support protrusion 267f can maintain the setting state of the balancer 26f.

[0340] like Figure 15 as well as Figure 18 As shown, the outer body 261f includes an outer body portion 261f' formed in a ring shape.

[0341] One side of the outer main body 261f' (i.e., the side facing the inner main body 264f) is formed with an outer moving groove 262f that covers the inner moving groove 265f of the inner main body 264f' and forms the flow path for the balancer ball and the fluid. The outer edge and inner edge of the outer moving groove 262f may form a plurality of outer welding grooves 2636f to 2638f and a plurality of outer welding protrusions 2631f to 2635f that intersect with the plurality of inner welding grooves 2641f to 2645f and the plurality of inner welding protrusions 2646f to 2648f formed on the inner main body 264f'.

[0342] On the other side of the aforementioned outer main body portion 261f', a plurality of ribs 2611f, 2612f, 2615f, and 2616f are formed for providing support for the aforementioned welding device. Support can be achieved through the aforementioned ribs 2611f, 2612f, 2615f, and 2616f, and will not interfere with the outer main body guide member G1 of the welding device (see reference). Figure 20 There was a shaking between them.

[0343] In the outer moving groove 262f of the outer main body 261f', on the side facing the outer main body 261f, along the center of the annular inner main body 264f', a space for the movement of balancer balls and fluid is formed.

[0344] The outer edge and inner edge of the aforementioned outer moving groove 262f are formed with a plurality of outer welding grooves 2636f~2638f and a plurality of outer welding protrusions 2631f~2635f. The plurality of outer welding grooves 2636f~2638f and the plurality of outer welding protrusions 2631f~2635f are formed to extend in a ring along the forming direction of the aforementioned outer moving groove 262f, and intersect with the plurality of inner welding grooves 2641f~2645f and the plurality of inner welding protrusions 2646f~2648f formed in the aforementioned inner body 264f.

[0345] Specifically, on the outer edge of the aforementioned outer moving groove 262f, along the direction from the outer edge of the aforementioned outer moving groove 262f toward the inner edge, a first outer welding protrusion 2631f, a first outer welding groove 2636f, and a second outer welding protrusion 2632f are sequentially formed.

[0346] The protruding lengths of the first outer weld protrusion 2631f and the second outer weld protrusion 2632f are shorter than the depths of the first inner weld groove 2641f and the second inner weld groove 2642f of the inner main body portion 264f'. Furthermore, the depth of the first outer weld groove 2636f is formed to be longer than the height of the first inner weld protrusion 2646f of the inner main body portion 264f'.

[0347] That is, the first outer welding protrusion 2631f and the second outer welding protrusion 2632f formed in the outer main body are inserted into the first inner welding groove 2641f and the second inner welding groove 2642f of the inner main body 264f', and the first inner welding protrusion 2646f of the inner main body 264f' is inserted into the first outer welding groove 2636f of the outer main body 261f'.

[0348] Wherein, the lengths of the first outer weld protrusion 2631f and the second outer weld protrusion 2632f inserted into the first inner weld groove 2641f and the second inner weld groove 2642f are formed to be shorter than the first inner weld groove 2641f and the second inner weld groove 2642f, thereby forming remaining space inside the first inner weld groove 2641f and the second inner weld groove 2642f when the first outer weld protrusion 2631f and the second outer weld protrusion 2632f are inserted.

[0349] This remaining space serves as a space for the welding residue generated in the welding protrusions 2646f~2648f, 2631f~2635f and welding grooves 2641f~2645f, 2636f~2638f to flow into and solidify during ultrasonic welding of the inner body 264f and the outer body 261f. The welding residue that solidifies after flowing into this remaining space allows for more efficient welding of the inner body 264f and the outer body 261f.

[0350] Furthermore, a first gap Da can be formed between the first inner weld groove 2641f and the second inner weld groove 2642f used for inserting the first outer weld protrusion 2631f and the second outer weld protrusion 2632f, so that a portion of the weld residue generated between each weld protrusion and each weld groove can be discharged to the outside of the first inner weld groove 2641f and the second inner weld groove 2642f. (Ref) Figure 21 )

[0351] In order to form the first gap Da, the first outer weld protrusion 2631f and the second outer weld protrusion 2632f inserted into the first inner weld groove 2641f and the second inner weld groove 2642f can be offset from the center of the first inner weld groove 2641f and the second inner weld groove 2642f.

[0352] That is, the first outer welding protrusion 2631f and the second outer welding protrusion 2632f are formed to be offset from the center of the first inner welding groove 2641f and the second inner welding groove 2642f, and are connected to the side facing the first gap Da, and separated from the side facing the first gap Da, thereby communicating with the first gap Da.

[0353] As the inner body 264f and the outer body 261f are welded together, the first gap Da can shrink into the second gap Db. As the second gap Db is formed, the welding residue flowing into the first gap is solidified after shrinking to the second gap Db, thereby further improving the welding force between each welding protrusion and each welding groove.

[0354] On the other hand, the aforementioned first outer welding protrusion 2631f and the aforementioned second outer welding protrusion 2632f can be formed to be the same as or longer than the first gap Da. That is, the aforementioned first outer welding protrusion 2631f and the aforementioned second outer welding protrusion 2632f can be formed to be adjacent to the aforementioned first inner welding groove 2641f and the aforementioned second inner welding groove 2642f at least before the welding of the aforementioned inner body and the aforementioned outer body is carried out, and to be inserted into the aforementioned first inner welding groove 2641f and the aforementioned second inner welding groove 2642f after the welding begins.

[0355] Therefore, the weld material generated between the first outer weld protrusion 2631f and the second outer weld protrusion 2632f and the first inner weld groove 2641f and the second inner weld groove 2642f can move towards the first gap Da through the trap-like flow path formed between the first outer weld protrusion 2631f and the second outer weld protrusion 2632f and the first inner weld groove 2641f and the second inner weld groove 2642f.

[0356] On the inner edge of the aforementioned outer moving groove 262f, along the direction from the outer edge of the aforementioned outer moving groove 262f toward the inner edge, a third outer welding protrusion 2633f, a second outer welding groove 2637f, a fourth outer welding protrusion 2634f, a third outer welding groove 2638f, and a fifth outer welding protrusion 2635f are formed in sequence.

[0357] The second outer weld groove 2637f and the third outer weld groove 2638f have the same shape and are configured to form the fourth outer weld protrusion 2634f in the middle. The third outer weld protrusion 2633f and the fifth outer weld protrusion 2635f are formed to be higher than the fourth outer weld protrusion 2634f.

[0358] The third outer welding protrusion 2633f and the fifth outer welding protrusion 2635f are inserted into the third inner welding groove 2643f and the fifth inner welding groove 2645f of the inner main body portion 264f', and the fourth inner welding protrusion 2634f is inserted into the fourth inner welding groove 2644f.

[0359] The lengths of the third outer welding protrusion 2633f and the fifth outer welding protrusion 2635f are made shorter than the depths of the third inner welding groove 2643f and the fifth inner welding groove 2645f. When the third outer welding protrusion 2633f and the fifth outer welding protrusion 2635f are inserted into the third inner welding groove 2643f and the fifth inner welding groove 2645f, there is remaining space inside the third inner welding groove 2643f and the fifth inner welding groove 2645f.

[0360] This remaining space serves to form a space in which welding residue generated in the welding protrusions and welding grooves during ultrasonic welding of the inner body 264f and the outer body 261f can flow in and solidify. The welding residue that solidifies after flowing into this remaining space allows for more efficient welding of the inner body 264f and the outer body 261f. This remaining space can also be formed within the fourth inner welding groove 2644f, which is used to insert the fourth outer welding protrusion 2634f.

[0361] In addition, a gap may be formed between the third inner weld groove 2643f and the fifth inner weld groove 2645f used for inserting the third outer weld protrusion 2633f and the fifth outer weld protrusion 2635f, so that a portion of the weld residue generated between each weld protrusion and each weld groove can be discharged to the outside of the third inner weld groove 2643f and the fifth inner weld groove 2645f.

[0362] As the inner body 264f and the outer body 261f are welded together, the gap can be reduced. As the gap is reduced, the welding residue flowing into the gap is solidified within the reduced gap, thereby further improving the welding force between each welding protrusion and each welding groove.

[0363] On the other side of the aforementioned outer main body portion 261f', a plurality of guide ribs 2611f, 2612f, 2615f, and 2616f are formed for providing support to the aforementioned welding device. Support can be achieved through the aforementioned ribs 2611f, 2612f, 2615f, and 2616f, and will not interfere with the outer main body guide member G1 of the welding device (see reference). Figure 20 There was a shaking between them.

[0364] Specifically, on the outer side of the outer main body 261f', along the annular shape of the outer main body 261f', the guide ribs 2611f, 2612f, 2615f, and 2616f are formed at the same center on the outer and inner edges of the outer main body 261f'.

[0365] On the outer edge of the aforementioned outer main body portion 261f', along the direction from the outer edge of the aforementioned outer main body portion 261f' toward the inner edge, a first outer guide rib 2611f and a first inner guide rib 2612f are formed. The aforementioned first inner guide rib 2612f is separated from the aforementioned first outer guide rib 2611f by a predetermined distance and forms an outer support surface 2614f.

[0366] The first outer guide rib 2611f and the first inner guide rib 2612f are formed to have the same center, and an outer dividing rib 2643f is formed between the first outer guide rib 2611f and the first inner guide rib 2612f to divide the annular outer support surface 2614f.

[0367] On the inner edge of the outer main body portion 261f', along the direction from the inner edge of the outer main body portion 261f' toward the outer edge, a second inner guide rib 2616f and a second outer guide rib 2615f are formed. The second outer guide rib 2615f is separated from the second inner guide rib 2616f by a predetermined distance and forms an inner support surface 2618f.

[0368] The second inner guide rib 2616f and the second outer guide rib 2615f are formed to have the same center, and an inner dividing rib 2617f is formed between the second inner guide rib 2616f and the second outer guide rib 2615f to divide the annular inner support surface 2618f.

[0369] The outer support surface 2614f, divided by the outer partition rib 2643f, and the inner support surface 2618f, divided by the inner partition rib 2617f, are supported by the outer main body guide G1 of the welding device described later, thereby supporting the outer main body 261f' in a wobbly state. When ultrasonic welding is performed, the outer main body 261f can vibrate without wobbling loss.

[0370] The welding process of the inner body 264f and the outer body 261f forming the balancer 26f will now be described with reference to the accompanying drawings.

[0371] Figure 20 This is a flowchart illustrating the engagement process of a balancer according to an embodiment of the present invention. Figure 21This is a simplified diagram illustrating the support structure of a welding device for welding a balancer according to an embodiment of the present invention.

[0372] like Figures 20 to 21 As shown, the balancer 26f of the present invention can be formed by welding using a welding device, which performs ultrasonic welding of the outer body 261f and the inner body 264f.

[0373] The aforementioned welding device imparts ultrasonic vibration (above 18 kHz) to the objects to be joined, and the objects are joined through frictional heat generated by the vibration energy. The joining quality of the objects to be joined can be determined based on their fixed state.

[0374] Although not shown, the above-described welding device may include a placement portion (not shown) for placing the inner body 264f, an inner body guide G2 for pressurizing and supporting the inner body 264f on the placement portion, and an outer body guide G1 for pressurizing the outer body 261f on the inner body 264f side while imparting ultrasonic vibration.

[0375] To weld the outer body 261f and the inner body 264f, the inner body 264f is placed in the placement portion of the welding device (step S110). On the other hand, as described above, the outer body 261f and the inner body 264f are injection molded from synthetic resin. During injection molding, shrinkage deformation may occur due to differences in cooling rates. Therefore, the roundness and flatness of the outer body 261f and the inner body 264f may be affected.

[0376] The inner body 264f, placed in the placement portion, is supported along the radial direction from the center of the inner body 264f by the inner body guide G2 and fixed to the placement portion (step S120). The inner circumferential surface of the inner body 264f has the inner support protrusion 2651f, which is supported along the radial direction by the inner body guide G2.

[0377] The inner main body guide G2 supports the inner support protrusion 2651f along the radial direction of the inner main body 264f, according to the roundness of the inner main body 264f as designed. Therefore, after being supported by the inner main body guide G2, the inner main body 264f is supported in a state with a roundness close to that of the design level.

[0378] In the aforementioned inner body 264f, an inner support protrusion 2651f is formed along the inner peripheral surface of the inner body portion 264f', and the aforementioned inner support protrusion 2651f is formed to have the same center as the aforementioned inner body 264f.

[0379] The aforementioned inner body guide G2 is formed to extend from the same center as the aforementioned inner body 264f and the aforementioned inner support protrusion 2651f in a radial direction toward the aforementioned inner body 264f, while supporting the inner side of the aforementioned inner support protrusion 2651f.

[0380] That is, the inner body guide G2 extends radially from the same center as the center of the inner body 264f and supports it, thereby supporting the inner body 264f while maintaining its roundness.

[0381] On the other hand, the end of the inner main body guide G2 is formed with an insertion groove G22 for inserting the inner support protrusion 2651f. The upper surface of the insertion groove G22 is formed with an inclined pressure surface G21 corresponding to the upper inclined surface 2651fa of the inner support protrusion 2651f. A radius pressure surface G23 supporting the inner circumferential surface of the inner main body 264f can be formed on one side of the insertion groove G22.

[0382] The upper inclined surface 2651fa of the aforementioned inner support protrusion 2651f is formed to slope downward toward the center of the aforementioned inner body 264f, and the aforementioned inclined pressure surface G21 is also formed to slope in the same direction as the aforementioned upper inclined surface 2651fa.

[0383] Therefore, as the inner main body guide G2 moves in the radial direction of the inner main body 264f, the inclined pressure surface G21 abuts against the upper inclined surface 2651fa, thereby applying pressure to the upper inclined surface 2651fa in the downward direction.

[0384] On the other hand, the inner body 264f, which is pressed downward by the inclined pressure surface G21, is placed in the placement part. The vertical support state can be fixed by the inner body guide G2. The placement part can achieve support while maintaining the flatness of the design level.

[0385] As the inner support protrusion 2651f is inserted into the insertion groove G22, the radius pressing surface G23 of the inner main body guide G2 presses against the inner circumferential surface of the inner main body 264f, thereby fixing the inner main body 264f.

[0386] That is, the inner body guide G2 extends from the center of the inner body 264f to the radius of the inner body 264f, and can fix the inner body 264f while maintaining the roundness of the inner body 264f at the design level, with the same center as the inner body 264f.

[0387] As described above, the inner body guide G2 can improve the flatness of the inner body 264f by applying pressure in the vertical direction and improve the roundness of the inner body 264f by applying pressure in the horizontal direction.

[0388] Then, the outer body 261f is placed on the upper part of the inner body 264f, which is supported by the inner body guide G2 in the placement part (step S130).

[0389] As the outer body is placed on the inner body, the outer weld portion (i.e., each weld protrusion and each weld groove formed on the lower surface of the outer body) and the inner weld portion (i.e., each weld groove and each weld protrusion formed on the upper surface of the inner body) intersect each other to form a weld position.

[0390] Then, ultrasonic vibration is applied to the outer body using the outer body guide (step S140). Corresponding to the shape of the outer body 261f, the outer body guide G1 can be formed as a ring, and its lower surface can be formed with an inner pressure protrusion G11 and an outer pressure protrusion G22 for applying pressure to the outer and inner edges of the outer body portion 261f'.

[0391] The aforementioned outer pressure protrusion G12 can be formed by protruding in a ring shape from the lower surface of the aforementioned outer main body guide G1, so as to be inserted into the space between the aforementioned first outer guide rib 2611f and the aforementioned first inner guide rib 2612f formed in the aforementioned outer main body portion 261f'.

[0392] On the other hand, the outer support surface 2614f formed by the first outer guide rib 2611f and the first inner guide rib 2612f is divided into a certain interval by the outer partition rib 2643f. Corresponding to the outer support surface 2614f divided by the outer partition rib 2643f, the outer pressure protrusion G12 can pressurize the outer body 261f at a certain interval.

[0393] The aforementioned inner pressure protrusion G11 can be formed by protruding in a ring shape from the lower surface of the aforementioned outer main body guide G1, so as to be inserted into the space between the aforementioned second outer guide rib 2615f and the aforementioned second inner guide rib 2616f formed in the aforementioned outer main body portion 261f'.

[0394] On the other hand, the inner support surface 2618f formed by the second outer guide rib 2615f and the second inner guide rib 2616f is divided into a certain interval by the inner partition rib 2617f. Corresponding to the outer support surface 2614f divided by the inner partition rib 2617f, the inner pressure protrusion G11 can press the outer body 261f at a certain interval.

[0395] At the upper part of the outer body 261f, the outer body guide G1 presses the outer body 261f towards the inner body 264f, and at the same time can transmit horizontal ultrasonic vibrations to the outer body portion 261f' so that the inner body 264f and the outer body 261f can be welded together.

[0396] In the outer main body guide G1, the outer supporting surface 2614f and the inner supporting surface 2618f are respectively supported by the annular outer supporting surface 2614f and the inner supporting surface 2618f, so that the ultrasonic vibration generated in the horizontal direction by the outer main body guide G1 can be effectively transmitted to the outer main body 261f.

[0397] Furthermore, the outer support surface 2614f and the inner support surface 2618f are separated by a certain interval by the outer partition rib 2643f and the inner partition rib 2617f, respectively. The outer pressure protrusion G12 and the inner pressure protrusion G11 are also inserted after being separated by a certain interval from the outer support surface 2614f and the inner support surface 2618f by the outer partition rib 2643f and the inner partition rib 2617f. In this case, the ultrasonic vibration in the circumferential direction generated by the outer main body guide G1 can also be effectively transmitted to the outer main body 261f.

[0398] Subsequently, due to the ultrasonic vibration transmitted to the outer body 261f through the outer body guide G1, the outer welding portion of the outer body 261f and the inner welding portion of the inner body 264f are welded together, thereby the inner body 264f and the outer body 261f can be welded together (step S150).

[0399] The welding state of the outer body 261f and the inner body 264f performed by the welding device described above will now be explained in detail with reference to the accompanying drawings.

[0400] Figure 22 This is a simplified diagram illustrating the welding process of a balancer according to an embodiment of the present invention.

[0401] As described above, the balancer 26f is formed by interleaving multiple outer welding protrusions 2631f~2635f and multiple outer welding grooves 2636f~2638f formed on the outer body 261f and multiple inner welding grooves 2641f~2645f and multiple inner welding protrusions 2646f~2648f formed on the inner body 264f, such that the contact surfaces of each welding protrusion 2631f~2635f, 2646f~2648f and each welding groove 2641f~2645f, 2636f~2638f are welded by ultrasonic vibration.

[0402] The inner body 264f and the outer body 261f are provided with multiple welding protrusions 631f~2635f, 2646f~2648f and multiple welding grooves 2641f~2645f, 2636f~2638f. Therefore, the welding protrusions 2631f, 2632f, 2646f and welding grooves 2636f, 2641f, 2642f formed on the outer edges of the inner body 264f and the outer body 261f will be described as an example.

[0403] As shown in the figure, the outer edge of the inner body 264f is sequentially formed with the first inner welding groove 2641f, the first inner welding protrusion 2646f, and the second inner welding groove 2642f, and the outer body 261f is sequentially formed with the first outer welding protrusion 2631f, the first outer welding groove 2636f, and the second outer welding protrusion 2632f.

[0404] The insertion states of the aforementioned welding protrusions 2631f, 2632f, 2646f and welding grooves 2636f, 2641f, 2642f are described as follows: the first outer welding protrusion 2631f is inserted into the first inner welding groove 2641f, the second outer welding protrusion 2632f is inserted into the second inner welding groove 2642f, and the first inner welding protrusion 2646f is inserted into the first outer welding groove 2636f.

[0405] At this point, with the outer peripheral surface of the first inner welding protrusion 2646f in contact with the inner peripheral surface of the first outer welding groove 2636f, remaining space can be formed inside the first outer welding groove 2636f. Furthermore, the first outer welding protrusion 2631f can be separated from the first inner welding groove 2641f by a predetermined interval to form remaining space, and the second outer welding protrusion 2632f can be separated from the second inner welding groove 2642f by a predetermined interval to form remaining space.

[0406] In addition, the inner body 264f and the outer body 261f form a first gap Da, which can communicate with the remaining space formed by the first outer welding protrusion 2631f and the first inner welding groove 2641f, as well as the remaining space formed by the second outer welding protrusion 2632f and the second inner welding groove 2642f.

[0407] In order to form the first gap Da, the first outer weld protrusion 2631f inserted into the second inner weld groove 2642f is positioned off-center from the center of the second inner weld groove 2642f.

[0408] That is, the first outer welding protrusion 2631f is formed to be offset from the center of the second inner welding groove 2642f and to be connected to the side facing the first gap Da, and to be separated from the side facing the first gap Da, thereby communicating with the first gap Da.

[0409] Therefore, the weld material generated between the first outer weld protrusion 2631f and the second inner weld groove 2642f can move towards the first gap Da through the space between the first outer weld protrusion 2631f and the second inner weld groove 2642f.

[0410] On the other hand, the aforementioned first outer welding protrusion 2631f is formed to be the same as or longer than the first gap Da. The aforementioned first outer welding protrusion 2631f may be formed to be adjacent to the aforementioned second inner welding groove 2642f at least before the welding of the aforementioned inner body and the aforementioned outer body is carried out, and after the welding begins, it is inserted into the aforementioned first inner welding groove 2641f and the aforementioned second inner welding groove 2642f.

[0411] Therefore, the weld material generated between the first outer weld protrusion 2631f and the second inner weld groove 2642f can move toward the first gap Da through the trap-like flow path formed between the first outer weld protrusion 2631f and the second inner weld groove 2642f.

[0412] In the aforementioned inner body 264f and outer body 261f, the inner body guide G2 of the welding device generates ultrasonic vibration while applying pressure, thereby pressing the inner body 264f against the outer body 261f, and through ultrasonic vibration, welding occurs at the joint surface of the first inner welding protrusion 2646f and the first outer welding groove 2636f.

[0413] The weld material generated at the joint surface of the first inner weld protrusion 2646f and the first outer weld groove 2636f can flow into the remaining space formed by the first inner weld protrusion 2646f and the first outer weld groove 2636f.

[0414] In addition, the weld material generated at the joint surface of the first inner weld protrusion 2646f and the first outer weld groove 2636f can flow into the remaining space formed by the first outer weld protrusion 2631f and the first inner weld groove 2641f, as well as the remaining space formed by the second outer weld protrusion 2632f and the second inner weld groove 2642f.

[0415] In addition, the welding material flowing into the remaining space formed by the first outer welding protrusion 2631f and the first inner welding groove 2641f and the remaining space formed by the second outer welding protrusion 2632f and the second inner welding groove 2642f fills the first inner welding groove 2641f and the second inner welding groove 2642f and can be discharged into the first gap Da.

[0416] Subsequently, as the first gap Da, which is pressurized by the inner body 264f and the outer body, contracts to the second gap Db, the weld material discharged into the first gap Da can achieve the welding of the first outer weld protrusion 2631f with the first inner weld groove 2641f and the second outer weld protrusion 2632f with the second inner weld groove 2642f.

[0417] Based on the configuration structure of the first outer welding protrusion 2631f, the first inner welding groove 2641f, the second outer welding protrusion 2632f, and the second inner welding groove 2642f, as described above, and the formation of the first gap Da, the inner body 264f and the outer body 261f can be effectively welded together.

[0418] As described above, preferred embodiments of the present invention have been detailed. However, those skilled in the art can implement the present invention in various modifications without departing from the spirit and scope of the invention as defined in the appended claims. Therefore, any changes to subsequent embodiments of the present invention cannot depart from the technical scope of the present invention.
