Description

Technical Field

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

[0002] Clothing handling equipment refers to washing machines that wash items such as clothes through a washing cycle and dryers that dry items through a drying cycle. Typically, washing machines and dryers are provided as separate units. However, there are also clothing handling devices that can perform washing and drying simultaneously to overcome space limitations and improve user convenience.

[0003] In order to perform a washing cycle, the laundry processing equipment includes a cabinet, a tank in which water is stored, a roller that provides space for accommodating items to be processed, a drive unit fixed to the tank to rotate the roller, a support arranged to support the tank, a water supply section arranged to supply water to the tank, and a drainage section arranged to drain water from the tank.

[0004] To perform a drying cycle, the garment handling equipment includes: a flow channel arranged to draw air from the drum and resupply the air to the drum; and a heat exchanger disposed in the flow channel to sequentially perform dehumidification and heating of the air.

[0005] In other words, there are traditional garment processing devices where the equipment for the washing cycle and the equipment for the drying cycle are both located in a cabinet, allowing users to selectively execute the washing and drying cycles according to their convenience.

[0006] The structure described above for traditional garment processing equipment is difficult to apply to commercial garment processing equipment that requires frequent and rapid processing of large quantities of items.

[0007] Commercial garment processing equipment is typically configured to handle larger volumes of garments than home garment processing equipment, or to process heavy garments such as blankets.

[0008] Therefore, commercial garment handling equipment requires processing space to accommodate heavy and bulky garments, as well as heat exchangers for rapid washing and drying of the items, making it difficult to install washing and drying equipment within a limited cabinet size. While it's possible to install washing and drying equipment in a large cabinet, this presents challenges in manufacturing and transportation. Therefore, the connection and arrangement of washing and drying equipment is a crucial design consideration for commercial garment handling equipment.

[0009] Furthermore, during high-load drying cycles, the increased flow rate of exhaust and supply hot air can lead to greater accumulation of foreign matter, such as lint. This material can then accumulate on the heat exchanger and reduce the effective heat transfer area, potentially significantly degrading drying performance. This underscores the critical importance of high-performance filtration.

[0010] However, given the demanding operating characteristics of commercial dryers, the conventional filters provided in general dryers often lack the necessary structural robustness. Furthermore, poor accessibility makes regular inspection and cleaning of the filters difficult.

[0011] Therefore, developing a filter arrangement and connection structure that is easy to replace, attach, and disassemble is a key challenge in this technical field. Summary of the Invention

[0094] Singular expressions include plural expressions unless the context clearly indicates otherwise. In this disclosure, terms such as “comprising,” “including,” or “having” are intended to specify the presence of stated features, numbers, steps, operations, components, parts, or combinations thereof, and do not exclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof, unless otherwise defined.

[0095] Expressions indicating relative or absolute arrangement (such as “in a certain direction,” “along a certain direction,” “parallel,” “perpendicular,” “centered,” “concentric,” or “coaxial”) are intended not only to express such arrangement strictly, but also to express the state of relative displacement with tolerances or angles or distances that achieve essentially the same function.

[0096] Furthermore, the terms used in this specification, including ordinal numbers such as "first" and "second," may be used to describe various components, but these components are not limited by these terms, and these terms are only used for the purpose of distinguishing one component from another. Thus, a first component may be named a second component, and similarly, a second component may be named a first component.

[0097] Furthermore, terms such as “front,” “rear,” “upper,” “lower,” “side,” “front end,” “rear end,” “top,” and “bottom” used in this specification are defined based on the drawings or on the arrangement / state of the components or between the components, and the shape and position of each component are not limited by these terms.

[0098] Hereinafter, preferred embodiments of the garment processing equipment and its control method will be described in detail with reference to the accompanying drawings.

[0099] like Figure 1 and Figure 2 As shown, the garment processing device 100 may include a first processing device (or processing module or washing module) 100a and a second processing device (or drying module, heat exchange module or detachable module) 100b. The first processing device 100a provides space for washing or drying items to be processed (e.g., garments), and the second processing device 100b is detachably connected to the first processing device 100a for drying items to be processed that have been introduced into the first processing device 100a.

[0100] The first processing device 100a may include a first cabinet 1, while the second processing device 100b may include a second cabinet 6. As shown, the second processing device 100b may be located on the first processing device 100a. In this case, the exterior of the garment processing device 100 may be defined by the first cabinet 1 and the second cabinet 6.

[0101] The first processing device 100a can be installed as a stand-alone unit to perform a washing cycle. When the second processing device 100b is subsequently connected to it, the second processing device 100b can perform a drying cycle to remove moisture from the clothes.

[0102] Therefore, in this disclosure, when the first processing device 100a is arranged separately, the first processing device 100a can be used as a washing machine. When the first processing device 100a and the second processing device 100b are arranged together, the clothes processing device 100 can be used as both a washing machine and a dryer.

[0103] As a result, depending on the user's situation and choice, only the first processing device 100a can be installed, or the second processing device 100b can be connected to the first processing device 100a and installed.

[0104] Specifically, when the first processing device 100a is configured to process large quantities of clothing like a commercial clothing processing device and therefore its overall size is larger than that of a household clothing processing device, the option of selectively connecting the second processing device 100b may be more useful for users who may have installation space limitations.

[0105] In addition, since the second processing device 100b is set separately from the first processing device 100a, it can prevent excessive increase in the size, volume and weight of the first processing device 100a, and it can also facilitate the manufacturing process of the first processing device 100a and the second processing device 100b, as well as the process of installing or transporting the first processing device 100a and the second processing device 100b.

[0106] The first cabinet 1 may include a front panel (first front panel) 11 that defines the front surface of the first processing device 100a, a side panel (first side panel) 12 that is connected to the first front panel to define the side surface of the first processing device 100a, and a rear panel (first rear panel) 13 that is disposed facing the first front panel 11 and defines the rear surface of the first processing device 100a.

[0107] The first front panel 11 may be provided with a control panel 112 for controlling the garment processing device 100. The control panel 112 may be configured to control only one of the first processing device 100a and the second processing device 100b, or it may be configured to control both the first processing device 100a and the second processing device 100b.

[0108] like Figure 2 As shown, the first front panel 11 may include a first panel body 113 and a second panel body 114. The first panel body 113 may be configured as a panel fixed to the first processing device 100a to define the installation space for the control panel 112, and the second panel body 114 may be configured as a panel detachable from the first processing device 100a.

[0109] The first panel body 113 may include a cabinet through-hole 111 communicating with the interior of the first processing device 100a, and the second panel body 114 may be positioned to expose at least some components disposed inside the first processing device 100a to the exterior of the first processing device 100a.

[0110] The second panel body 114 can be detachably arranged below the first panel body 113. Even when a wall or another household appliance is installed on one side of the first cabinet 1, the second panel body 114 can be detached and connected without being affected.

[0111] When the second panel body 114 is removed, at least some of the electrical components located in the first cabinet 1 can be inspected, repaired or replaced.

[0112] Figure 2 As an example, a first panel body 113 defines the upper region of the first front panel 11 and a second panel body 114 defines the lower region of the first front panel 11.

[0113] The first side panel 12 may include a left panel (first left panel) 121 that defines the left side surface of the first processing device 100a (a part of the left side surface of the clothing processing device) and a right panel (first right panel) 122 that defines the right side surface of the first processing device 100a (a part of the right side surface of the clothing processing device).

[0114] like Figure 2 As shown, the first processing device 100a may be provided with an installation space 15, and the second processing device 100b is fixed to the installation space 15. The installation space 15 may be configured as an open space formed in the top surface of the first cabinet 1. Figure 2 As an example, the mounting space 15 is defined by the upper end of the first front panel 11, the upper end of the first left panel 121, the upper end of the first right panel 122, and the upper end of the first rear panel 13.

[0115] The height of the first front panel 11 and the height of the first rear panel 13 can be set to be greater than the height of the first left panel 121 and the height of the first right panel 122 (by H). Setting the height of the first front panel 11 and the first rear panel 13 to be greater than the height of the side panels 121 and 122 is advantageous for positioning and fixing the second processing device 100b during the installation of the second processing device 100b in the installation space 15, while also reducing the overall height of the garment processing device 100.

[0116] Furthermore, by setting the height of the first front panel 11 to be greater than the height of the side panels 121 and 122, space can be created that allows other devices (such as detergent storage units) to be installed on the first front panel 11, while minimizing the increase in height of the garment handling equipment 100. The bottom surface of the second cabinet 6 and the top surface of the first cabinet 1 can be directly connected to each other without any gaps between them.

[0117] Therefore, when the second cabinet 6 is placed on the first cabinet 1, the first cabinet 1 and the second cabinet 6 can be arranged parallel in the height direction, and the second cabinet 6 can be regarded as extending vertically from the first cabinet 1.

[0118] In addition, it can prevent moisture or outside air from flowing into the connection between the second cabinet 6 and the first cabinet 1.

[0119] A first controller 19, configured to control at least one of the first processing device 100a and the second processing device 100b, may be disposed within the first cabinet 1. The first controller 19 may be configured to receive control signals from the input unit of the control panel 112, or to send control signals for displaying request information to the display of the control panel 112. The controller may be fixed to the first rear panel 13.

[0120] An accommodating section 3 may be provided inside the first cabinet 1, defining a washing or drying space for items to be processed. As an example, Figure 3 The illustration shows a case where the containing part 3 includes a bucket 3a that defines a water storage space and an air movement path, and a roller 3b that can be rotatably arranged inside the bucket to define a space for containing items to be processed.

[0121] The tank 3a may include a tank body 30, which provides space for storing water and is fixed inside the first cabinet 1 by a tank support 34.

[0122] The barrel body 30 may be formed as a hollow cylinder. The barrel body 30 may include a barrel front surface 31 disposed on the side facing the first front panel 11, a barrel rear surface 31a disposed on the side facing the first rear panel 13, and a barrel circumferential surface 31b connecting the barrel front surface 31 and the barrel rear surface 31a.

[0123] The front surface 31 of the drum may be provided with a drum inlet 311 communicating with the interior of the roller 3b, and a connecting body 312 formed to surround the drum inlet 311 and protrude from the front surface 31 toward the cabinet through hole 111.

[0124] In other words, the connecting body 312 can be configured as a cylinder protruding from the front surface 31 of the bucket toward the first front panel 11, and the bucket inlet 311 can be configured as a hole formed through the front surface 31 of the bucket and located inside the connecting body 312.

[0125] The connecting body 312 not only provides installation space for the injector or barrel air supply section 35a, which will be described later, but also serves as a device for guiding the items to be processed into the roller 3b through the cabinet through-hole 111 toward the barrel inlet 311.

[0126] When door 2 is connected to first cabinet 1 to open and close bucket inlet 311, vibrations from bucket 3a can be transmitted to door 2 and first cabinet 1. When bucket 3a is made of metal and is relatively heavy, and also contains a large amount of water and clothing, door 2 and first cabinet 1 may not be able to stably withstand the forces and vibrations transmitted from bucket 3a.

[0127] Therefore, in the garment handling apparatus of this disclosure, the door 2 can be installed on the drum 3a. When the door 2 is connected to the drum 3a, the door 2 can vibrate as a whole with the drum 3a, thereby preventing the door 2 from being damaged or broken due to the vibration of the drum 3a.

[0128] In addition, since the position of the door 2 opening and closing the barrel inlet 311 is fixed, the door 2 can stably seal the barrel inlet 311 even when the barrel 3a vibrates.

[0129] That is, the barrel inlet 311 can be opened and closed via a door 2 that is rotatably fixed to the front surface 31 of the barrel. For example... Figure 2 As shown, door 2 is fixed to the first front panel 11 without rotation, but is rotatably fixed to the barrel body 30. Therefore, the cabinet through-hole 111 can be sized and positioned such that it does not interfere with the rotation of door 2 (for opening or closing the entrance).

[0130] When the bucket inlet 311 is closed, door 2 remains exposed to the outside of the first cabinet 1 through the cabinet through-hole 111. However, when the bucket inlet 311 is open, door 2 can rotate outward from the first cabinet 1 through the cabinet through-hole 111.

[0131] like Figure 3As shown, in order to secure the door 2 to the front surface 31 of the barrel, the barrel 3a may be provided with a door mounting portion T / D. The door mounting portion T / D may include a first mounting cover 32 secured to the front surface 31 of the barrel to surround the connecting body 312, and a second mounting cover 33 secured to the first mounting cover 32 and on which a hinge 27 for mounting the door is mounted.

[0132] To prevent the bucket inlet 311 from being blocked by the door mounting part T / D, the first mounting cover 32 may be provided with a first inlet communication hole 322 communicating with the bucket inlet 311, and the second mounting cover 33 may be provided with a second inlet communication hole 334 communicating with the bucket inlet 311 and the first inlet communication hole 322.

[0133] The barrel 3a can be connected to the second processing device 100b via the barrel air supply section 35a and the barrel exhaust section 35b. That is, the second processing device 100b can be detachably connected to the barrel air supply section 35a and the barrel exhaust section 35b.

[0134] The air supply section 35a can be configured to supply air to the barrel body 30 via the connecting body 312, and the air exhaust section 35b can be configured to exhaust air from the barrel body 30 to the outside of the barrel 3a via the barrel circumferential surface 31b.

[0135] The air supply section 35a may include a first air supply port 351 and a second air supply port 352 disposed in the connecting body 312, and a distribution pipe 353 for guiding air to each air supply port 351 and 352.

[0136] The first air supply port 351 and the second air supply port 352 may be arranged to pass through the connecting body 312 to communicate with the barrel inlet 311. The distribution pipe 353 may include a connecting pipe 353a connected to the second processing device 100b, a first branch pipe 353b that guides a portion of the air introduced into the connecting pipe 353a to the first air supply port 351, and a second branch pipe 353c that guides a portion of the air introduced into the connecting pipe 353a to the second air supply port 352.

[0137] In order for the garment handling equipment 100 to perform washing or drying of a large number of items, it is necessary to design the volume of the drum body 30 and the drum 3b to be relatively large. Since the drum 3b must be supported by the rear surface 31a of the drum and can rotate within the drum body 30, the durability of the drum body 30 is important for designing the drum 3b to have a large volume. Therefore, the drum body 30 can be made of metal.

[0138] When the barrel body 30 is made of metal, the connecting body 312 is also preferably made of metal, while the dispensing pipe 353 can be made of a different material than the connecting body 312. The dispensing pipe 353, having the aforementioned first and second branches, may be more advantageous in terms of cost and time when molded from a material such as plastic rather than metal. Therefore, when the dispensing pipe 353 and the connecting body 312 are made of different materials, the first processing apparatus 100a may also include a support 354 for connecting the dispensing pipe 353 to the connecting body 312.

[0139] The distribution pipe 353 can be configured as a flow channel protruding from the connecting body 312 toward the second processing device 100b. The free end of the connecting pipe 353a (i.e., the portion connected to the second processing device) can be arranged to expose the first processing device 100a to the outside through the mounting space 15 of the first cabinet 1. That is, the free end of the connecting pipe 353a can be arranged at a point higher than the upper end of the first front panel 11. This is to facilitate the connection between the first processing device 100a and the second processing device 100b.

[0140] The barrel exhaust portion 35b can be configured as an exhaust pipe protruding from the barrel circumference toward the surface 31b toward the second processing device 100b. That is, the barrel exhaust portion 35b can be configured as an exhaust pipe protruding toward the mounting space 15 formed on the upper surface of the first processing device 100a.

[0141] The free end of the exhaust section 35b (the part connected to the second processing device) can be positioned at a point higher than the upper end of the side panel 12, or it can be positioned at a point lower than the upper end of the side panel 12. The former facilitates the connection between the first processing device 100a and the second processing device 100b. The latter reduces the height of the garment processing device 100.

[0142] like Figure 4 As shown, the door 2 may include a door frame 20 that is rotatably fixed to a hinge 27, a door frame through hole 20a formed through the door frame, and a door window 23 fixed to the door frame 20 to close the door frame through hole.

[0143] The door frame through-hole 20a can be located at a position corresponding to the barrel inlet 311 (i.e., a position communicating with the inlet), and the door / window 23 can be formed of a light-transmitting material. In this case, the user can inspect the interior of the roller 3b from the outside of the first processing device 100a.

[0144] The door and window 23 may include a first window (outer window) 23a and a second window (inner window) 23b. The first window (outer window) 23a is fixed to the door frame 20 so as to be exposed to the outside through the cabinet through hole 111, and the second window (inner window) 23b is fixed to the door frame 20 so as to be positioned inside the connecting body 312.

[0145] The first window 23a may be configured as glass located in the cabinet through-hole 111 to form part of the first front panel 11, and the second window 23b may be configured as glass protruding from the door frame 20 toward the barrel inlet 311.

[0146] Water can be supplied to the main body 30 through the water supply section 5, and the water inside the main body 30 can be discharged to the outside of the clothing processing equipment 100 through the drainage section 39.

[0147] The drainage section 39 may include a drain pipe 391 that directs water from the tank body 30 to the outside of the first cabinet 1. The drain pipe 391 may be configured as a flexible hose, with one end fixed to the lower space of the circumferential surface 31b of the tank (the area of ​​the circumferential surface of the tank located below the horizontal line passing through the center of the inlet), and the opposite end extending through the first rear panel 13.

[0148] The drain pipe 391 can be arranged to drain the water in the tank body 30 to the outside of the first cabinet 1 by gravity, or it can be arranged to use the drain pump 393 to drain the water in the tank body 30 to the outside of the first cabinet 1. Figure 4 The first case is shown as an example. In this case, the drainage section 39 may also include a drain valve 392, which is configured to control the opening and closing of the drain pipe 391 according to a control signal from the first controller 19.

[0149] The drainage section 39 may also include a drainage filter for filtering water flowing into the drain pipe 391. The drainage filter may be arranged separately from the drain pipe 391. The drain valve 392 and the drainage filter may be located in positions where they are exposed to the outside when the second panel body 114 is separated from the first treatment device 100a.

[0150] The roller 3b may include a roller body 36, which is formed as a hollow cylinder and located inside the barrel body 30.

[0151] A roller inlet 361 communicating with the barrel inlet 311 may be formed in the front surface of the roller body 36, and a plurality of roller through holes 363 that allow the interior of the roller body to communicate with the interior of the barrel body 30 may be formed in the circumferential surface of the roller body 36.

[0152] Additionally, the lifter 362 can be located inside the drum 3b, protruding from the inner surface of the drum body 36 toward the rotation center of the drum body 36, to aid in the movement of clothing contained in the drum 3b.

[0153] like Figure 5As shown, the drum body 36 can be rotated via the drum shaft 37 and the drive unit 38. The drum shaft 37 can be fixed to the rear surface of the drum body 36 and arranged through the rear surface 31a of the drum, and the drive unit 38 can be positioned outside the drum body 30 to rotate the drum shaft 37.

[0154] The drive unit 38 may include a bearing housing 382 fixed to the rear surface 31a of the drum to rotatably fix the roller shaft 37 to the drum body 30, a motor 383 fixed to the drum support 34, and a power transmitter configured to transmit power from the motor to the roller shaft 37. The motor 383 may be controlled by the first controller 19.

[0155] The bearing housing 382 can be fixed to the rear surface 31a of the barrel via the drive unit support body 381. The drive unit support body 381 may include: a hub to which the bearing housing 382 is fixed; and a plurality of hub fixing rods arranged radially from the hub.

[0156] A through-hole is provided in the rear surface of the barrel 31a, and a hub through-hole connected to the through-hole is provided in the hub. The roller shaft 37 is exposed to the outside of the barrel body 30 through the through-hole in the rear surface and the hub through-hole. The roller shaft 37 exposed to the outside of the barrel body 30 is rotatably fixed to the hub by the bearing housing 382.

[0157] The power transmitter may include a first pulley 385 fixed to a rotating shaft 384 of a motor, a second pulley 386 fixed to a roller shaft 37, and a belt 387 connecting the two pulleys.

[0158] As described above, the barrel body 30 is fixed inside the first cabinet 1 by the barrel support 34 and is supplied with water through the water supply section 5.

[0159] The bucket support 34 may include a first support body 341 and a second support body 345. The first support body 341 defines the bottom surface of the garment handling device 100, and the second support body 345 is disposed on the first support body 34 and provides space therein for fixing the bucket body 30.

[0160] The barrel body 30 can be fixed to the second support body 345 by a barrel fixing member 348. The barrel fixing member 348 may include a first band 348a and a second band 348b for fixing the circumferential surface 31b of the barrel to the second support body 345.

[0161] The first band 348a can be arranged to fix the front region of the circumferential surface 31b of the barrel to the second support body 345, and the second band 348b can be arranged to fix the rear region of the circumferential surface 31b of the barrel to the second support body 345.

[0162] To reduce the vibration of the barrel body 30, the second support body 345 can be connected to the first support body 341 via a damper 346 and a spring 347.

[0163] In addition, to reduce vibration of the barrel body 30, the first processing device 100a may also include barrel counterweights 349a and 349b. Barrel counterweights 349a and 349b may include at least one of a first counterweight 349a fixed to the second support body 345 and a second counterweight 349b fixed to the circumferential surface 31b of the barrel.

[0164] The water supply section 5 is a device for guiding water from a water source located outside the laundry handling equipment 100 to the drum body 30. The water supply section 5 can be configured as a flow path that directly connects the water source and the drum body 30, or as a flow path that supplies detergent along with water supplied from the water source to the drum body 30. Figure 5 The latter case is shown as an example.

[0165] The water supply section 5 may include a detergent storage section 51 defining a space for storing detergent, a storage section water supply pipe 52 arranged to supply water from a water source to the detergent storage section 51, and a water supply valve 54 configured to control the opening and closing of the storage section water supply pipe 52 according to a control signal from a first controller 19 (see [link]). Figure 3 ), and a bucket supply pipe 55b arranged to supply liquid (water, or a mixture of water and detergent) discharged from the detergent storage section 51 to the bucket body 30.

[0166] The detergent storage section 51 may include a housing body 51a fixed to the first front panel 11 and positioned within the first cabinet 1, and a housing cover 51b fixed to the housing body 51a to define the top surface of the detergent storage section 51. A drawer outlet may be provided in the first front panel 11 such that a drawer 51c can be removed from the detergent storage section 51 to the outside of the first cabinet 1.

[0167] The detergent storage space 516 disposed in drawer 51c may include multiple spaces for individually storing detergent. In the following description, the multiple spaces of the detergent storage space 516 including a first storage portion 517, a second storage portion 518, and a third storage portion 519 will be described as examples.

[0168] In this case, the water supply pipe 52 may include a first water supply pipe 521 arranged to supply water to the first storage section 517, a second water supply pipe 522 arranged to supply water to the second storage section 518, and a third water supply pipe 523 arranged to supply water to the third storage section 519.

[0169] Water and detergent discharged from drawer 51c to housing body 51a can move to the outside of housing body 51a through housing outlet, and water and detergent discharged from housing body 51a can move to tub body 30 through tub supply pipe 55b.

[0170] The housing cover 51b may also include an ejector supply flow channel configured to supply water to the ejector, as will be described later. In this case, the storage water supply pipe 52 may also include a fourth water supply pipe 524 connecting the water source and the ejector supply flow channel.

[0171] The first processing device 100a may include a communication portion 59 (external air communication portion) configured to supply external air to the barrel body 30 or allow external air to be supplied to the barrel body 30.

[0172] Water can be retained in the tub body 30 and the roller body 36, and the garment handling device 100 including the connecting part 59 can reduce the possibility of water being retained in the tub body 30 and the roller body 36, thereby enabling hygienic management of the tub 3a and the roller 3b.

[0173] Furthermore, even when the door 2 closes the tub inlet 311, the garment handling device 100, including the connecting portion 59, can prevent the interior of the tub body 30 from being sealed. Therefore, the garment handling device 100 can prevent accidents caused by sealing the tub body 30.

[0174] To prevent fluid (water, foam, or foreign matter) inside the tank body 30 from being discharged to the outside of the first cabinet 1 through the connecting part 59, the first processing device 100a may also include a connector 56 that connects the flow channel formed by the water supply part 5 and the flow channel formed by the connecting part 59.

[0175] like Figure 6 and Figure 7 As shown, the first processing device 100a may include a jet (a first washing unit 4a and a second washing unit 4b).

[0176] The jetting device (first washing unit 4a and second washing unit 4b) may include at least one of a first washing unit 4a fixed to the connecting body 312 to spray water toward the door 2 and a second washing unit 4b fixed to the connecting body 312 to spray water into the drum 3b.

[0177] Each of the first washing unit 4a and the second washing unit 4b can be configured to spray water supplied from a water source, or can be configured to spray water inside the tub body 30. The first washing unit 4a can be configured to spray water supplied from a water source, and the second washing unit 4b can be configured to spray water inside the tub body 30.

[0178] When the first washing unit 4a is configured to spray water supplied from a water source, the first washing unit 4a can receive water through a nozzle supply pipe connected to the sprayer supply flow channel.

[0179] The first processing device 100a may include a temperature sensor 318 configured to perform temperature measurement, and the connecting body 312 may include a mounting hole 317 on which the temperature sensor 318 is mounted.

[0180] Temperature sensor 318 may be configured to measure at least one of the temperature inside the roller body 36, the temperature of the item to be processed inside the roller body, and the temperature of the air supplied from the second processing device 100b. An infrared temperature sensor configured to measure the temperature of the item to be processed by sensing infrared light emitted from the item to be processed may be an example of temperature sensor 318.

[0181] In order to measure the temperature inside the drum body 36, the temperature of the item to be processed, or the temperature of the air supplied to the drum body 30, a temperature sensor 318 may be arranged in the upper region of the connecting body 312.

[0182] The second washing unit 4b may include a circulation pump 45 configured to move water within the tub body 30, a circulation nozzle 46 fixed to the connecting body 312 to spray water toward the drum inlet 361, and a circulation flow channel 47 connecting the circulation pump 45 and the circulation nozzle 46.

[0183] The circulation pump 45 may include: a pump chamber 451 configured to receive water from the tank body 30 via a drain pipe 391; a pump discharge pipe 454 connecting the pump chamber 451 to the circulation flow channel 47; and a pump motor 453 configured to rotate a pump impeller positioned within the pump chamber 451 to move water to the pump discharge pipe 454.

[0184] The pump discharge pipe 454, pump chamber 451, and pump motor 453 can be positioned within the space defined between the first support body 341 and the second support body 345. Therefore, when the second panel body 114 is separated from the first processing device 100a, the pump chamber 451 and pump motor 453 can be exposed to the outside of the first processing device 100a. Regarding the durability of the pump motor 453, it can be fixed to the first support body 341 and positioned between the first support body 341 and the second support body 345.

[0185] The circulation nozzle 46 may include a first nozzle 46a and a second nozzle 46b. The first nozzle 46a is fixed to the connecting body 312 and is located on the left side of the vertical line passing through the center of the barrel inlet 311, and the second nozzle 46b is fixed to the connecting body 312 and is located on the right side of the vertical line.

[0186] The first nozzle 46a can be fixed in the area between the highest point of the mounting tube and a point on the circumferential surface of the connecting body 312 that is 90 degrees counterclockwise from the highest point of the mounting tube, and the second nozzle 46b can be fixed in the area between the highest point of the mounting tube and a point on the circumferential surface of the connecting body 312 that is 90 degrees clockwise from the highest point of the mounting tube. Since the items to be treated are usually located on the bottom surface of the drum body 36 during the washing cycle, washing performance can be improved by arranging each of the nozzles 46a and 46b to spray water from above the horizontal line passing through the drum inlet 311 toward the bottom surface of the drum body 36.

[0187] The circulating flow channel 47 may include a connector 471 connected to a pump discharge pipe 454, a first circulating water supply pipe 476 arranged to guide water introduced into the connector 471 to a first nozzle 46a, and a second circulating water supply pipe 477 arranged to guide water introduced into the connector 471 to a second nozzle 46b.

[0188] Connector 471 is a device for setting the injection timing of the first nozzle 46a and the injection timing of the second nozzle 46b to be the same.

[0189] The connector 471 may include a connector body 472 fixed to the second support body 345, a connector flow channel 473 disposed inside the connector body 472 to receive water through a pump discharge pipe 454, a first connector discharge pipe 474 arranged to supply water inside the connector flow channel 473 to a first circulating water supply pipe 476, and a second connector discharge pipe 475 arranged to guide water inside the connector flow channel 473 to a second circulating water supply pipe 477.

[0190] The connector body 472 can be fixed to a surface of the second support body 345 via a connector bracket for positioning below the barrel inlet 311. Since the second support body 345 is connected to the first support body 341 via a damper 346 and a spring 347, the second support body 345 moves together with the barrel body 30 when the drum body 36 vibrates. Therefore, at least a portion of the pump discharge pipe 454 can be configured as a bellows.

[0191] In order to install the first nozzle 46a and the second nozzle 46b onto the connecting body 312, the connecting body 312 may include a circulating nozzle mounting section.

[0192] Figure 8 An example of the second processing device 100b is shown.

[0193] The second processing device 100b may include a second cabinet 6, flow channels 7 and 8 disposed within the second cabinet 6, and a heat exchanger 9 disposed in the flow channels and configured to remove moisture from the air (dehumidify) or heat the air.

[0194] The second cabinet 6 may include a support frame 61 mounted on the first cabinet 1, a side panel (second side panel) 65 fixed to the support frame 61 to define the side surface of the second cabinet, a rear panel (second rear panel) 64 fixed to the support frame 61 to define the rear surface of the second cabinet, and a top panel 66 fixed to the support frame 61 to define the top surface of the second cabinet.

[0195] The second rear panel 64 may be provided with a panel exhaust opening 641, which allows communication between the interior and exterior of the second cabinet 6. Therefore, air inside the second cabinet 6 can be exhausted to the outside through the panel exhaust opening 641, and outside air can be introduced into the second cabinet 6 through the port.

[0196] The frame panel 62 can be disposed on the front surface of the support frame 61. The frame panel 62 can define a space therein to support a portion of the flow channels 7 and 8.

[0197] Furthermore, the support frame 61 may include a front panel (second front panel) 67 defining the front surface of the second cabinet. The second front panel 67 may be shaped to surround the frame panel 62, such that the frame panel 62 is not exposed to the outside. In addition, to allow easy access to the frame panel 62 by the user, the second front panel 67 may be rotatably fixed to the support frame 61 or the frame panel 62.

[0198] When the second cabinet 6 is installed on the first cabinet 1, the lower end of the second side panel 65 can be connected to the upper end of the first side panel 12 of the first processing device, and the lower end of the second rear panel 64 can be connected to the upper end of the first rear panel 13. When the second cabinet 6 is installed on the first cabinet 1, the second front panel 67 can be positioned in the same plane as the first front panel 11.

[0199] When the second cabinet 6 is fixed to the upper part of the first cabinet 1, the upper end of the second side panel 65 and the upper end of the second front panel 67 can be at the same height to provide a seamless appearance.

[0200] The frame panel 62 may have the same height as the second front panel 67 and be disposed on the first front panel 11, or may be at least partially inserted into the first front panel 11, with its lower end disposed below the second front panel 67.

[0201] like Figure 9As shown, the support frame 61 may include a lower frame 611 detachably connected to the mounting space 15 of the first cabinet 1, an upper frame 617 located above the lower frame 611 and fixed with an upper panel 66, and a connecting frame 618 connecting the frames 611 and 617.

[0202] The front surface of the support frame 61 can be closed by the frame panel 62, the two side surfaces of the support frame 61 can be closed by the second side panel 65, the top surface of the support frame 61 can be closed by the upper panel 66, and the rear surface of the support frame 61 can be closed by the second rear panel 64.

[0203] As described above, 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 and the internal space of the support frame 61, a communication space 612 connected to the installation space 15 can be provided on the bottom surface of the support frame 61.

[0204] 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 can be defined as the area in the communicating space 612 where the support panel 613 is located, while the open surface can be defined as the area in the communicating space 612 where the support panel 613 is not located. Since the communicating space 612 is connected to the mounting space 15, the mounting space 15 can also be considered as being divided into an open surface and a closed surface by the support panel 613.

[0205] The interior of the support frame 61 can be divided into a front space 6a and a rear space 6b. A frame panel 62 is positioned in the front space 6a, and a second rear panel 64 is positioned in the rear space 6b. The support panel 613 can be fixed to the lower frame 611 and positioned in the rear space 6b.

[0206] The support panel 613 can be fixed to the lower frame 611 and arranged along the width direction (Y-axis direction) or length direction (X-axis direction) of the garment handling device. As an example, Figure 15 The diagram shows the support panel 613 arranged along the width of the garment handling equipment.

[0207] The support panel 613 may include a support body 614 and a fixing body 615. The support body 614 supports a part of the components of the flow channels 7 and 8 or a part of the components of the heat exchanger 9, and the fixing body 615 fixes the support body 614 to the lower frame 611.

[0208] The support body 614 can be positioned at a point lower than the lower frame 611. That is, the lowest point of the support body 614 can be located at a point lower than the bottom surface of the support frame 61 (the lowest point of the connecting space or the lower frame). When the second cabinet 6 is installed on the first cabinet 1, the edge of the bottom surface of the support frame 61 is supported by the panels 11, 12, and 13 of the first cabinet that define the installation space 15, and the support body 614 is located inside the first cabinet 1. In other words, when the second cabinet 6 is fixed to the first cabinet 1, the support body 614 can be located at a point lower than the upper end of the first side panel 12.

[0209] Since the support panel 613 is arranged to support the flow channels 7 and 8 or the heat exchanger 9, it is expected that positioning the support body 614 at a point lower than the lower frame 611 will reduce the overall height of the garment handling device 100.

[0210] The frame panel 62 may include a first panel through hole 621, a second panel through hole 622 and a third panel through hole 623, which allow the interior of the second cabinet 6 to communicate with the outside.

[0211] The first panel through-hole 621 can be opened and closed by the first panel door 624, which is rotatably fixed to the frame panel 62, and the second panel through-hole 622 can be opened and closed by the second panel door (or filter door) 626, which is rotatably fixed to the frame panel 62.

[0212] The first panel door 624 may be provided with space for installing a second controller 63, which is configured to control the second processing device 100b. In this case, the first panel through-hole 621 may serve as a controller outlet through which the second controller 63 is exposed to the outside of the second cabinet 6.

[0213] Filters can be installed in flow channels 7 and 8 to filter the air discharged from the tank body 30. In this case, the second panel through-hole 622 can be used as a filter outlet through which the filter can be removed from the second cabinet 6.

[0214] The third panel through-hole 623 can be used as a device (panel air inlet) to supply air from the outside of the second cabinet 6 to the flow channels 7 and 8.

[0215] like Figure 8 As shown, the flow channels may include a first flow channel 7 and a second flow channel 8. The first flow channel 7 is connected to the barrel body 30 to define the circulation path of the air, and the second flow channel 8 defines the movement path of the external air.

[0216] Figure 10 The structure of flow channels 7 and 8 of the second processing device 100b is shown.

[0217] Figure 11 An exploded view of flow channels 7 and 8 is shown.

[0218] The first flow channel 7 can define a flow path through which air contained in the barrel 3a can be introduced, moved to the outside of the barrel 3a, and reintroduced into the barrel 3a.

[0219] The first flow channel 7 may include an exhaust flow channel 71 connected to the barrel exhaust section 25, an air supply flow channel 72 connected to the barrel air supply section 24, a heat exchange flow channel 73 connected to the exhaust flow channel, and a blowing flow channel 74, in which a fan for moving air is installed, and the blowing flow channel 74 connects the heat exchange flow channel 73 and the air supply flow channel 72.

[0220] The exhaust flow passage 71 may include an exhaust pipe 711 that is detachably fixed to the barrel exhaust section 25 of the first processing equipment.

[0221] In the garment processing equipment, the exhaust pipe 711 may include a first exhaust pipe 711a that is detachably arranged on the drum 3a, and a second exhaust pipe 711b that is connected at one end to the first exhaust pipe 711a and at the opposite end to the filter pipe 73a.

[0222] The second exhaust pipe 711b can be located in front of the first exhaust pipe 711a to receive air from the barrel 3a, and the front surface of the second exhaust pipe 711b can be an inclined surface with the upper end positioned further forward than the lower end.

[0223] In order to reduce the transmission of vibration of the barrel body 30 to the heat exchange flow channel 73, at least a portion of the exhaust pipe 711 may be provided with an exhaust flow channel corrugated portion 712.

[0224] The air supply flow channel 72 may include an air supply pipe 721, which is fixed to the blowing flow channel 74 and provides a path for the air discharged from the blowing flow channel. In order to reduce the transmission of vibration of the barrel body 30 to the air supply pipe 721, at least a portion of the air supply pipe 721 or one end of the air supply pipe 721 may be provided with an air supply flow channel corrugated section 722.

[0225] The heat exchange flow channel 73 may include a heat exchange pipe 73b fixed to the support panel 613. The heat exchange pipe 73b may include a first heat exchange pipe 734, a second heat exchange pipe 735, and a connecting pipe connecting the heat exchange pipes 734 and 735. A first heat exchanger included in the heat exchanger 9 is installed in the first heat exchange pipe 734, and a second heat exchanger included in the heat exchanger 9 is installed in the second heat exchange pipe 735.

[0226] The heat exchange pipe 73b can be fixed to the bottom surface of the support panel 613 (support body 614), or it can be fixed to the pipe mounting part 616 provided on the support panel 613. The pipe mounting part 616 is a device that protrudes from the support body 614 into the heat exchange pipe 73b to maintain the gap between the bottom surface of the heat exchange pipe 73b and the support body 614.

[0227] Air introduced from the tank body 30 into the first heat exchange pipe 73b through the exhaust pipe 711 condenses as it passes through the first heat exchanger. Therefore, condensate can be retained within the heat exchange pipe 73b. To drain the condensate remaining in the heat exchange pipe 73b, the second processing device 100b may be provided with a condensate drain section 75. The condensate drain section 75 may be arranged in the space defined by the pipe mounting section 616 between the bottom surface of the heat exchange pipe 73b and the support body 614.

[0228] The heat exchange pipe 73b can be directly connected to the exhaust pipe 711, or it can be connected to the exhaust pipe 711 through the filter pipe 73a.

[0229] The filter duct 73a may include: an inlet 732 disposed in the bottom surface of the filter duct 73a to receive air from the exhaust flow passage 71, a duct filter 77 configured to filter the air introduced through the inlet 732; and an outlet 733 disposed in the rear surface of the filter duct 73a to discharge the air filtered by the duct filter 77 to the heat exchanger 9.

[0230] The front surface of the filter conduit 73a may be an open surface communicating with the interior of the filter conduit 73a. The open surface may include a filter removal opening 731.

[0231] In one embodiment of this disclosure, one surface of the filter conduit 73a may be provided with a filter removal opening (or open surface) 731 communicating with the second panel through hole 622, and the other surface of the filter conduit 73a may be provided with an inlet 732 connected to the exhaust conduit 711. As an example, the figure shows a case where the filter removal opening 731 is provided in the front surface (surface facing the frame panel) of the filter conduit 73a and the inlet 732 is provided in the bottom surface of the filter conduit 73a.

[0232] Filter duct 73a is a space in which a duct filter 77 is installed, which is used to filter the air to be supplied to exhaust duct 711.

[0233] As described above, air flowing through the filter duct 73a is introduced through an inlet 732 provided in the bottom surface and discharged through an outlet 733 provided in the rear surface. Therefore, the duct filter 77 can be arranged at an angle within the filter duct 73a to increase the contact area with the flowing air.

[0234] The airflow channel 74 may include an airflow duct 74a fixed to the support panel 613 and connected to the heat exchange duct 73b and the air supply duct 721, and an airflow fan (or first airflow channel fan) 74b for moving air along the first airflow channel 7.

[0235] like Figure 12 As shown, the second flow channel 8 may include: a first external air duct 82 disposed within the second cabinet 6 to allow external air to be introduced through it; a second external air duct 83 connected to the first external air duct 82 and provided with a third heat exchanger 93 included in the heat exchanger 9; and a second flow channel fan 84 configured to move air.

[0236] The first external air duct 82 can be configured as a flow channel extending along the longitudinal direction (X-axis direction) of the second cabinet, and the second external air duct 83 can be configured as a flow channel extending along the height direction (Z-axis direction) of the second cabinet. One surface of the second external air duct 83 can be provided with a duct through-hole 831 to allow air to be exhausted to the second flow channel fan 84.

[0237] The second flow channel fan 84 may include a second fan housing 841 fixed to the second external air duct 83 to close the duct through-hole 831 and provided with a second impeller 846, a housing inlet 842 connected to the duct through-hole 831 and allowing air to be introduced into the second fan housing 841 therethrough, a housing outlet 843 allowing air inside the second fan housing 841 to be discharged into the second cabinet 6 therethrough, and a second fan motor 845 fixed to the second fan housing 841 and configured to rotate the second impeller 846.

[0238] When the second impeller 846 is rotated by the second fan motor 845, external air can be introduced into the second fan housing 841 through the first external air duct 82 and the second external air duct 83, and the air inside the second fan housing 841 can be discharged into the second cabinet 6 through the housing outlet 843. The air discharged into the second cabinet 6 can be discharged from the second cabinet 6 through the panel exhaust opening 641 provided in the second rear panel 64.

[0239] like Figure 13 As shown, one surface of the first external air duct 82 can be fixed to the frame panel 62, and the other surface of the first external air duct 82 can be fixed to the fixed frame 619.

[0240] like Figure 12 As shown, the first external air duct 82 may be arranged to receive external air through at least one of a first inlet hole 821 or a second inlet hole 822. The first inlet hole 821 may be connected to a panel air supply hole provided in the frame panel 62, and the second inlet hole 822 may be connected to a second outlet hole 636 provided in the plate fixing portion 631.

[0241] The first inlet hole 821 and the second inlet hole 822 can receive air from outside the second cabinet 6 through the external air supply hole 81 provided in the second front panel 67. As an example, Figure 13 The illustration shows an external air supply vent 81 located in the top surface of the second front panel 67. However, the external air supply vent 81 may also be located in the side or bottom surface of the second front panel 67.

[0242] The heat exchanger 9 may include: a first heat exchanger 91 disposed in a first heat exchange conduit 737 to remove moisture from the air; a second heat exchanger 92 disposed in a second heat exchange conduit 738 to heat the air; a third heat exchanger 93 disposed in a second flow passage 8 to exchange heat with the outside air; a refrigerant pipe 96 defining a circulation flow passage through which the refrigerant passes through the heat exchangers 91, 92 and 93; and a compressor 94 configured to move the refrigerant along the refrigerant pipe.

[0243] like Figure 12 As shown, the refrigerant pipe 96 may be equipped with a control valve 97 and a switching unit 95. The control valve 97 is arranged to control the pressure of the refrigerant, and the switching unit 95 is arranged to control the movement path of the refrigerant discharged from the second heat exchanger 92.

[0244] The refrigerant line 96 may include: a first refrigerant flow passage 961 that guides refrigerant discharged from the compressor 94 to the second heat exchanger 92; a second refrigerant flow passage 962 that guides refrigerant (which has already exchanged heat with air in the second heat exchanger) through the second heat exchanger 92 to the switching unit 95; a third refrigerant flow passage 963 and a fourth refrigerant flow passage 964 that connect the switching unit 95 and the third heat exchanger 93; a fifth refrigerant flow passage 965 that connects the switching unit 95 and the first heat exchanger 91; and a sixth refrigerant flow passage 966 that guides refrigerant through the first heat exchanger 91 to the compressor 94. In this case, a control valve 97 may be disposed in the third refrigerant flow passage 963 and positioned between the switching unit 95 and the third heat exchanger 93.

[0245] The switching unit 95 can allow refrigerant supplied through the second refrigerant flow channel 962 to be supplied to the third refrigerant flow channel 963 or the fourth refrigerant flow channel 964.

[0246] When the switching unit 95 allows refrigerant to be supplied to the third refrigerant flow channel 963, the refrigerant passes through the control valve 97 and is then supplied to the third heat exchanger 93. The refrigerant passing through the third heat exchanger 93 is recovered to the switching unit 95 via the fourth refrigerant flow channel 964, and then supplied to the first heat exchanger 91 via the fifth refrigerant flow channel 965. In this case, the third heat exchanger 93 performs the same function (heat absorption function) as the first heat exchanger 91.

[0247] When the switching unit 95 allows refrigerant to be supplied to the fourth refrigerant flow channel 964, refrigerant is supplied to the third heat exchanger 93. The refrigerant passing through the third heat exchanger 93 is recovered to the switching unit 95 via the third refrigerant flow channel 964 and control valve 97, and then supplied to the first heat exchanger 91 via the fifth refrigerant flow channel 965. In this case, the third heat exchanger 93 performs the same function (heating function) as the second heat exchanger 92.

[0248] Figure 14 A side sectional view of the filter duct 73a and the exhaust flow passage 71 together with the rest of the first flow passage 7 is shown.

[0249] As the amount of clothing introduced into the drum 3b increases, the required flow rate through the first flow channel 7 may increase, and the volume of the heat exchanger 9 may also increase.

[0250] Therefore, the first flow channel 7 can be configured to allow air to move in one lateral direction within the second cabinet 6, and then deliver air again in the opposite lateral direction. Thus, by increasing the length of the first flow channel 7, a heat exchanger 9 with a larger volume can be accommodated.

[0251] When the gas supply section 35a is arranged in the central part of the width direction of the barrel 3a, the drying efficiency of the barrel 3a can be maximized. Therefore, the gas supply pipe 721 should be located in the central part of the width direction of the second cabinet 6, and thus the heat exchange flow channel 73 can be set to one side in the width direction of the second cabinet 6 to ensure that the volume of the heat exchanger 9 can be accommodated and to improve the drying efficiency.

[0252] The filter duct 73a can be installed on one side along the front-to-back direction of the second cabinet 6.

[0253] In one embodiment of this disclosure, the filter pipe 73a is disposed upstream of the first flow channel 7, and the tank air supply section 35a is disposed in front of the tank 3a. Therefore, the filter pipe 73a can be disposed in front of the second cabinet 6. Thus, air moving from front to back along the heat exchange flow channel 73 can again be conveyed from back to front along the blowing flow channel 74 and the air supply flow channel 72, and discharged into the tank 3a, thereby ensuring sufficient volume to accommodate the heat exchanger 9.

[0254] Since the gas supply section 35a is located on the front side, the gas exhaust section 35b can be located on the opposite rear side of the gas supply section 35a.

[0255] The first exhaust pipe 711a can deliver air discharged through the barrel exhaust section 35b from back to front, and the second exhaust pipe 711b can deliver air from bottom to top.

[0256] Since the airflow delivered to the second exhaust duct 711b is directed forward and the exhaust airflow is directed upward, the front surface of the second exhaust duct 711b can be configured as an inclined surface, with its upper end positioned further forward than its lower end. Therefore, resistance caused by changes in the flow direction of the air flowing through the second exhaust duct 711b can be minimized.

[0257] The entire front surface of the filter conduit 73a can be configured as an open surface to define the filter removal opening 731.

[0258] The bottom surface of the filter pipe 73a may include a first region A1 and a second region A2. The first region A1 is connected to the front surface of the filter pipe 73a and is provided with an inlet 732. The second region A2 is located behind the first region A1 and forms the rest of the bottom surface of the filter pipe 73a.

[0259] The filter conduit 73a may include a filter mounting portion 736 fixed to the filter conduit 73a to connect the conduit filter 77 to the filter conduit 73a.

[0260] The pipeline filter 77 can be detachably arranged in the filter pipeline 73a. For example, a connecting magnet 776 connected to a magnetic material can be accommodated in the pipeline filter 77, and at least a portion of the filter pipeline 73a can be formed of a magnetic material, such that the pipeline filter 77 can be detachably attached to the filter pipeline 73a.

[0261] The second door (filter door) 626 may be rotatably mounted on the frame panel 62 to open and close the filter removal opening 731.

[0262] Therefore, the user can rotate the second front panel 67 to expose the frame panel 62 forward and open the filter door 626 to remove or insert the pipe filter 77 through the filter removal opening 731.

[0263] The duct filter 77 may include a surface through which air is introduced and another surface through which air is discharged. The other surface may be detachably arranged in the filter duct 73a.

[0264] In one embodiment of this disclosure, another surface of the duct filter 77 may be detachably attached to the filter mounting portion 736. Since air flows from one surface of the duct filter 77 to the other surface and exerts an external force on the other surface by the flow pressure, separation of the duct filter 77 can be prevented by fixing the other surface to the filter mounting portion 736.

[0265] Figure 15 The filter pipe 73a and the exhaust pipe 711 are shown.

[0266] The pipe filter 77 installed in the filter pipe 73a can be arranged at an angle in the filter pipe 73a to relatively increase the contact area with air.

[0267] The filter duct 73a may be equipped with a duct filter 77. The duct filter 77 may be inclinedly disposed inside the filter duct 73a, such that its upper end is positioned further forward than its lower end. Therefore, as the air supplied to the filter duct 73a moves upward and backward, the air can be transported in a direction nearly perpendicular to the flow pressure direction, and the contact area with the air can be maximized, thereby improving filtration performance.

[0268] The duct filter 77 may include a first filter 77a and a second filter 77b, the second filter 77b being arranged to receive and re-filter the air filtered by the first filter 77a.

[0269] One end of the second filter 77b can be fixed to the bottom surface of the filter pipe 73a.

[0270] The second filter 77b may be inclined relative to the bottom surface of the filter pipe 73a, unlike the first filter 77a.

[0271] Compared to the first filter 77a, the second filter 77b can be arranged at a greater angle relative to the bottom surface of the filter pipe 73a.

[0272] Air filtered through the first filter 77a can exert a reduced upward flow pressure compared to air filtered through the second filter 77b.

[0273] Therefore, when the air passing through the first filter 77a moves in a direction more parallel to the rear surface of the filter duct 73a, the second filter can be arranged with a greater inclination relative to the bottom surface of the filter duct 73a than the first filter 77a, so as to receive air in a direction nearly perpendicular to the flow pressure, thereby ensuring the reliability of filtration.

[0274] The first filter 77a and the second filter 77b are compatible with each other.

[0275] The filter duct 73a may include a mounted sensor configured to sense whether the duct filter 77 is attached.

[0276] Multiple sensors can be provided to sense the first filter 77a and the second filter 77b respectively.

[0277] The first filter 77a and the second filter 77b can be connected to each other. In this case, the sensor can be configured to sense the attachment of only one of the first filter 77a and the second filter 77b.

[0278] The end of the second exhaust pipe 711b connected to the filter pipe 73a may have the same dimensions as the inlet 732. This end may form the first region A1 of the filter pipe 73a.

[0279] The filter conduit 73a may include a pressure sensor configured to sense blockage in the conduit filter 77 by the downstream pressure of the conduit filter 77. Blockage in the conduit filter 77 can be detected when the pressure value sensed by the pressure sensor is less than or equal to a reference value.

[0280] The pressure sensor can be a differential pressure sensor to sense the pressure difference between the upstream and downstream sides of the pipeline filter 77. Therefore, when the sensed pressure difference is greater than or equal to a reference value, blockage of the pipeline filter 77 can be detected.

[0281] The first filter 77a may include a first-1 end 771 fixed to the bottom surface of the filter pipe 73a and a first-2 end 772 extending from the first-1 end 771 and having at least a portion disposed on the front surface of the filter pipe 73a.

[0282] The front surface of the filter conduit 73a is provided with a filter removal opening 731, which is an open surface. Therefore, when the filter door 626 is opened, the first and second ends 772 can be exposed to the front, and thus the first filter 77a can be easily removed to the outside for cleaning and maintenance.

[0283] Therefore, the first and second ends 772 may be provided with a handle 783, which can be gripped by a user to facilitate the removal and insertion of the first filter 77a.

[0284] Figure 16 An example of a filter pipe 73a equipped with a first filter 77a and a second filter 77b is shown.

[0285] As described above, the first filter 77a may include a first-1 end 771 fixed to the bottom surface of the filter conduit 73a and a first-2 end 772 extending from the first-1 end 771 and having at least a portion disposed on the front surface of the filter conduit 73a, such that the first-2 end 772 is exposed facing forward. Therefore, the first filter 77a can be easily removed to the outside for cleaning and maintenance.

[0286] The second filter 77b may include a second-1 end 773 fixed to the filter pipe 73a and a second-2 end 774 disposed above the first-2 end 772 of the first filter 77a and having at least a portion disposed on the front surface of the filter pipe 73a. Therefore, the second-2 end 774 can also be easily inserted into and removed from the filter pipe 73a through the filter removal opening 626.

[0287] As the amount of clothing processed per cycle by the garment handling equipment 100 increases, the replacement cycle of filters for foreign matter and lint may increase. Therefore, accessibility can be improved by providing multiple duct filters 77 and arranging at least one end of them to be exposed through the filter removal opening 731.

[0288] Because the air filtered by the first filter 77a exerts a reduced upward flow pressure compared to the air filtered by the second filter 77b, the second filter 77b can be arranged to be more inclined relative to the bottom surface of the filter duct 73a than the first filter 77a.

[0289] The second-to-second end 774 of the second filter 77b can be positioned at the upper end of the filter outlet 731. Therefore, the additional pipeline filter 77 can be easily accommodated between the first filter 77a and the second filter 77b.

[0290] The second-1 end 773 of the second filter 77b can be fixed to the bottom surface of the filter pipe 73a, and the second-1 end 773 can be positioned behind the first-1 end 771.

[0291] When the second filter 77b's second-1 end 773 is positioned on the bottom surface of the filter pipe 73a behind the first filter 77a's first-1 end 771, interference between the first filter 77a and the second filter 77b can be prevented, thus facilitating installation. Furthermore, due to the increased filtration area of ​​the second filter 77b, its replacement cycle can be extended, and its filtration efficiency can be improved.

[0292] The second-1 end 773 of the second filter 77b can be positioned at the same location as the first-1 end 771 of the first filter 77a, or positioned behind the first-1 end 771 of the first filter 77a. In this case, when the second-2 end 774 of the second filter 77b is arranged at the upper end of the filter outlet 731, the area of ​​the filter in contact with the air passing through the filter pipe 73a can be maximized.

[0293] The second-1 end 773 of the second filter 77b can be fixed above the first-1 end 771 of the first filter 77a.

[0294] The first filter 77a's first-1 end 771 can be fixed to the rear end of the second region. In this case, when the second filter 77b's second-1 end 773 is fixed above the first filter 77a's first-1 end 771, the duct filter 77 can cross a relatively large cross section of the air flowing through the filter duct 73a, thereby improving filtration efficiency.

[0295] The first-1 end 771 of the first filter 77a and the second-1 end 773 of the second filter 77b can be connected to each other. Therefore, when the first filter 77a is separated from the filter conduit 73a, the second filter 77b can also be separated from the filter conduit 73a. In this case, the sensor can be configured to sense the attachment of the second-2 end 774 of the second filter 77b. Therefore, when the first filter 77a and the second filter 77b are attached to or removed from the filter conduit 73a, the complete attachment or removal of the conduit filter 77 can be detected solely based on the attachment or removal of the last responding second-2 end 774.

[0296] Handles 783 may be provided on the first-second end 772 and the second-second end 774 exposed by the filter removal opening 731. These handles can be gripped by the user, thereby improving the accessibility of inserting and removing the pipeline filter 77.

[0297] Figure 17 An example of a filter pipe 73a equipped with a first filter 77a and a second filter 77b is shown.

[0298] The first filter 77a may include a first-1 end 771 fixed to the bottom surface of the filter conduit 73a and a first-2 end 772 extending from the first-1 end 771 and having at least a portion disposed on the front surface of the filter conduit 73a. The first-2 end 772 may be disposed at the upper end of the filter outlet 731.

[0299] The first-1 end 771 of the first filter 77a can be fixed to the rear end of the second region A2. The amount of impurities filtered out by the first filter 77a is the largest. Therefore, when the first-2 end 771, which is the upper end of the first filter 77a, is fixed to the upper end of the front surface of the filter pipe 73a, and the first-1 end 771, which is the lower end of the first filter 77a, is fixed to the rear end of the bottom surface of the filter pipe 73a, the cross-sectional area of ​​the air in contact with the first filter 77a can be maximized, thereby improving the filtration efficiency.

[0300] The second filter 77b may include a second-1 end 773 fixed to the bottom surface of the filter pipe 73a and a second-2 end 774 fixed to the top surface of the filter pipe 73a.

[0301] The second-2 end 774 can be positioned in front of the second-1 end 773. Therefore, when the first filter 77a is removed through the filter removal opening 731, the second-2 end 774 can be exposed. Thus, the user can remove the second filter 77b to the outside of the filter pipe 73a through the second-2 end 774 or the handle 783 provided on the second-2 end 774.

[0302] The second-1 end 773 of the second filter 77b can be located at the same position as the first-1 end 771 of the first filter 77a or located behind the first-1 end 771 of the first filter 77a.

[0303] The second-1 end 773 of the second filter 77b can be fixed above the first-1 end 771 of the first filter 77a.

[0304] Figure 18 (a) shows one embodiment of a filter pipe 73a provided with a first filter 77a and a second filter 77b.

[0305] The first-1 end 771 of the first filter 77a can be fixed to the bottom surface of the filter pipe 73a, and the first-2 end 772 can be fixed to the upper end of the front surface of the filter pipe 73a.

[0306] The second-1 end 773 of the second filter 77b can be located above or overlap with the first-1 end 771, and the second-2 end 774 can be fixed to the upper end of the rear surface of the filter pipe 73a.

[0307] In this case, the first-1 end 771 of the first filter 77a and the second-1 end 773 of the second filter 77b can be located at the front end of the second region A2.

[0308] Figure 18 (b) shows one embodiment of a filter pipe 73a provided with a first filter 77a and a second filter 77b.

[0309] The first-1 end 771 of the first filter 77a can be fixed to the bottom surface of the filter pipe 73a, while the first-2 end 772 can be fixed to the lower end of the front surface of the filter pipe 73a.

[0310] That is, the first filter 77a can be arranged to close the inlet 732. The first-1 end 771 can be fixed to the front end of the second region A2, and the first-2 end 772 can be fixed to the front end of the first region A1, such that the size of the first filter 77a corresponds to the inlet 732.

[0311] The second-1 end 773 of the second filter 77b can be located above or overlap with the first-1 end 771, and the second-2 end 774 can be fixed to the upper end of the front surface of the filter pipe 73a.

[0312] Therefore, when both end 1-2 772 and end 2-2 774 are exposed through the filter removal opening 731, it is convenient to replace and clean the pipeline filter 77.

[0313] Figure 19 An example of the filter fixing part 736 is shown.

[0314] The second area A2 and the filter fixing part 736 can be integrally formed.

[0315] The filter fixing part 736 may include a first filter fixing part 736a arranged to fix the first filter 77a and a second filter fixing part 736b arranged to fix the second filter 77b.

[0316] The filter fixing part 736 may include a side rib 7361 fixed to the opposite side surface of the filter pipe 73a, and a rear rib 7362 connecting the rear end of the side rib 7361. That is, the filter fixing part 736 may be arranged so as not to extend through the front surface of the filter pipe 73a.

[0317] Since the side rib 7361 is fixed to the side surface of the filter pipe 73a, unfiltered air can be prevented from leaking through the gap between the side surface of the filter pipe 73a and the side rib 7361.

[0318] Therefore, by pushing or pulling the front end of the pipe filter located on the front surface of the filter pipe 73a, the user can easily insert and remove the pipe filter 77.

[0319] The duct filter 77 may include a surface through which air is introduced and another surface through which air is discharged, and the other surface may be detachably connected to the filter duct 73a.

[0320] In one embodiment of this disclosure, another surface of the duct filter 77 may be detachably attached to the filter mounting portion 736. Since air flows from one surface of the duct filter 77 to the other surface and exerts an external force on the other surface by the flow pressure, separation of the duct filter 77 can be prevented by fixing the other surface to the filter mounting portion 736.

[0321] The rear rib 7362 can be fixed to the bottom surface of the filter duct 73a. Therefore, unfiltered air can be prevented from leaking through the gap between the rear rib 7362 and the second region A2.

[0322] The rear rib 7362 of the second filter fixing part 736b can be fixed to the rear rib 7362 of the first filter fixing part 736a. The rear ribs 7362 can be arranged without spacing between each other, thereby preventing unfiltered air from leaking between the two rear ribs 7362.

[0323] Figure 20 One embodiment of the pipe filter 77 is shown.

[0324] At least one of the first filter 77a and the second filter 77b can be configured as follows. The first filter 77a and the second filter 77b can be compatible with each other. Compatible pipeline filters 77 can be configured as follows.

[0325] The duct filter 77 may include a frame portion 770 formed along the inner peripheral surface of the filter duct 73a, a filter screen 775 having an edge fixed by the frame portion 770 and arranged to filter air, and a shape retaining member 778 inserted into the frame portion 770 to maintain the shape of the frame portion 770.

[0326] The frame portion 770 may include a first frame 78 exposed to the outside of the filter pipe 73a and a second frame 79 fixed to the filter pipe 73a, wherein the first frame may be connected to the second frame 79.

[0327] The shape-retaining member 778 can be inserted between the second frame 79 and the first frame 78.

[0328] The shape-retaining member 778 may be formed of a material having a higher stiffness than at least one of the second frame 79 and the first frame 78 to prevent the frame portion 770 from deforming.

[0329] The filter screen 775 can provide inward tension to the frame portion 770 to resist the tension applied to the edge of the filter screen 775 by the frame portion 770. Therefore, due to the tension of the filter screen 775, torque may be generated in the frame portion 770. The shape-retaining member 778 can be formed of a material with sufficient torsional stiffness to resist the torque generated in the frame portion 770, thereby preventing the frame portion 770 from twisting.

[0330] Figure 21 This is a schematic diagram illustrating the process of manufacturing the frame section 770. Figure 22 This is a flowchart illustrating the process of manufacturing the frame section 770. Referencing the following text... Figure 21 and Figure 22 Describe the process of manufacturing the frame section 770.

[0331] The frame portion 770 can be manufactured by a method comprising an extrusion operation S1 in which the material of the frame portion 770 is heated to a high temperature and the material is continuously extruded into a product having a constant cross-section, a cutting operation S2 in which the material processed by the extrusion operation S1 is cut according to the length of each side of the pipe filter 77, and a fusion operation S3 in which the ends of the material processed by the cutting operation S2 are heated and thermally fused to correspond to the shape of the opening 350.

[0332] Therefore, since the frame portion 770, which extends in a closed-loop shape along the inner circumferential surface of the filter pipe 73a, is not manufactured integrally by injection molding or the like, the initial mold manufacturing cost can be reduced, and the range of selectable materials for the frame portion 770 can be expanded.

[0333] Furthermore, since the processing is performed only by compressive and shear stress, the degree of freedom can be increased in terms of the shape of the cross-sectional portion formed within the frame portion 770 for fixing the shape-holding member 778 and / or the filter screen 775.

[0334] A fusion line L1, formed by the thermal fusion of the various ends of the material, can be formed in the frame portion 770. The fusion line L1 may not be clearly distinguishable visually.

[0335] During the fusion process, the fusion line L1 can be identified by using a polymer that is different from the material constituting the frame portion 770.

[0336] Because the ends of the material processed by the extrusion operation S1 and the cutting operation S2 are deformed by physical forces such as heat, the fusion line L1 may only need to be distinguished from other parts in terms of shape, structure, and physical properties. The fusion line L1 may only need to be identified by those skilled in the art as a feature resulting from fusion.

[0337] The second frame 79 and the first frame 78 can be manufactured with different cross-sections or materials.

[0338] Figure 21 (a) shows a method for manufacturing the first frame 78. Figure 21 (b) shows a method for manufacturing the second frame 79.

[0339] The first frame 78 can be manufactured by a method including a first frame extrusion operation S1a, a first frame cutting operation S2a for cutting the material processed by the first frame extrusion operation S1a, and a first frame fusion operation S3a for thermally fusing the ends of the material by heating the ends of the material.

[0340] The first frame fusion line L11 can be formed in the first frame 78 through the first frame fusion operation S3a.

[0341] The connecting magnet 776 that generates magnetic force can be housed within the second frame 79, and at least a portion of the filter pipe 73a can have a magnetic material capable of being connected to the connecting magnet 776, so that the second frame 79 can be detachably fixed to the filter pipe 73a.

[0342] Since the connecting magnet 776 can be housed in the second frame 79, the second frame 79 can be manufactured as follows.

[0343] The second frame 79 can be manufactured by a method including the following steps: a second frame extrusion operation S1b, a second frame cutting operation S2b that cuts the material processed by the second frame extrusion operation S1b, an insertion operation S25 that accommodates the connecting magnet 776 in the cut material, and a second frame fusion operation S3b that heats and thermally fuses the end of the material accommodating the connecting magnet 776.

[0344] That is, since the connecting magnet 776 should be housed in an attachment object such as the second frame 79, an insertion operation S25 for accommodating the connecting magnet 776 may also be included after the cutting operation S2.

[0345] To prevent the coupling magnet 776 from separating and to improve attachment reliability, the coupling magnet 776 can be inserted into the coupling magnet receiving groove 7913, which will be described later and is formed separately within the second frame 79. Therefore, the insertion operation S25 can be performed after the cutting operation S2 and before the fusion operation S3.

[0346] Through the second frame fusion operation S3b, a second frame fusion line L12 can be formed on the second frame 79.

[0347] Figure 23 An example of a cross-section (hereinafter referred to as the "cross section") taken from the first frame 78 in a direction perpendicular to its compression direction is shown. Figure 24 An example of a cross-section (hereinafter referred to as the "cross section") of the second frame 79 taken in a direction perpendicular to its extrusion direction is shown. The characteristics of the cross section of the first frame 78 and the cross section of the second frame 79 will be described below.

[0348] When the second frame 79 and the first frame 78 are joined together to face each other on their contact surfaces, grooves 781 and 791 can be formed that protrude from or recess into the contact surfaces. The second frame 79 and the first frame 78 can be joined together by engaging the grooves 781 and 791.

[0349] At least one of the second frame 79 and the first frame 78 may be provided with shape-retaining member receiving grooves 784 and 794 to receive shape-retaining member 778.

[0350] The edge of the filter screen 775 can be fixed to the frame portion 770 by the pressure generated by the engagement of the groove portions 781 and 791 and the connection between the shape retaining member 778 and the frame portion 770.

[0351] The groove may include a first groove 791 protruding from a surface of the second frame 79 facing the first frame 78, and a second groove 781 recessed from a surface of the first frame 78 facing the second frame 79 to engage with the first groove 791.

[0352] When the first groove 791 is formed in a protruding shape, the degree of freedom in the position and shape of the connecting magnet receiving groove 792 can be increased.

[0353] Compared to the first frame 78, the second frame 79 can be positioned relatively downstream of the air flowing through the filter duct 73a.

[0354] The filter screen 775 can exert an external force on the frame portion 770 in the downstream direction due to airflow. In this case, when the first groove portion 791 is formed in a protruding shape and the second groove portion 781 is formed in a concave shape, the force of the groove portions 51 and 61 supporting the filter screen 775 in the upstream direction can be increased. Therefore, the filter screen 775 can be stably fixed to the frame portion 770 without being overly tensioned.

[0355] The grooves 781 and 791 may include a plurality of protrusions extending from the contact surface and a plurality of recesses engaging with the protrusions. The protrusions and recesses may be arranged in a line along a direction intersecting the extrusion (extension) direction of the frame portion 770. Therefore, the manufacturability of the frame portion 770 can be improved.

[0356] Preferably, the multiple protrusions and multiple recesses can be arranged in a line from the inside to the outside of the frame on each side of the frame portion 770. Therefore, the connecting force of the grooves 781 and 791 can be transmitted to the filter screen 775 with the strongest force, thereby allowing the filter screen 775 to be stably fixed to the frame portion 770.

[0357] The shape retaining member receiving grooves 784 and 794 can be formed between a plurality of recesses and a plurality of protrusions. Therefore, when the shape retaining member 778 is received in the frame portion 770, the grooves 781 and 791 can be joined in the inward and outward directions of the frame portion 770, thereby preventing the separation of the shape retaining member 778 and allowing the shape retaining member to be stably fixed.

[0358] A sealing rib 782 may be formed around the outer peripheral surface of the first frame 78 to protrude and expose the exterior of the filter duct 73a. When the duct filter 77 is fixed to the opening, the sealing rib 782 can prevent airflow through the joint between the outer peripheral surface of the frame portion 770 and the opening 350.

[0359] The sealing rib 782 can protrude from the edge of the frame portion 770 at an angle greater than the angle formed between the inner surfaces of the pipe filter 77 and the filter pipe 73a. Therefore, the sealing rib 782 and the inner surface of the pipe body 310 can naturally contact and press against each other, thereby effectively blocking airflow.

[0360] At least a portion of the first frame 78 may be provided with a handle 783 that protrudes outward from the filter pipe 73a for gripping by a user.

[0361] The user can pull the handle 783, which is exposed outside the filter pipe 73a, outward from the filter pipe 73a to separate the frame portion 770 from the opening 350. Therefore, usability is improved because the user does not need to insert their fingers into the narrow gap formed between the opening 350 and the outer peripheral surface of the frame portion 770 in order to separate the pipe filter 77.

[0362] The engagement force generated by the engagement of the slots 781 and 791 can be set to be greater than the attachment force for attaching the connecting magnet 776 to the filter pipe 73a, so that when the handle 783 is pulled, not only the first frame 78 but also the second frame 79 can be removed.

[0363] The protrusion angle and position of the handle 783 can be varied depending on the location of the pipe filter 77. The handle 783 can be arranged so that a user of average height can grip the handle 783 within the range of arm movement without standing on tiptoe or bending over.

[0364] The handle 783 may be provided with an anti-slip part 783a to improve user usability. The anti-slip part 783a may be provided in the form of a groove or protrusion corresponding to the shape of the fingers, or in a shape that prevents slipping, and may be formed separately from the frame part 770 and attached to the handle 783.

[0365] Figure 23 (a) shows an example of a first frame 78 provided with a handle 783 and a sealing rib 782, and Figure 23 (b) shows an example of a first frame 78 without a handle 783 or a sealing rib 782.

[0366] like Figure 24 As shown, the second frame 79 may be provided with a connecting magnet receiving groove 792 to accommodate the connecting magnet. The connecting magnet 776 may be formed of an elastic material so as to be easily accommodated in the connecting magnet receiving groove 792.

[0367] Figure 25 The grooves 781 and 791 provided on the second frame 79 and the first frame 78 are shown.

[0368] According to one embodiment of this disclosure, the second frame 79 may include a first groove 791 configured as a protrusion projecting from the contact surface, and the first frame 78 may include a second groove 781 configured as a recessed portion from the contact surface. However, this is merely one embodiment of this disclosure. Protrusions may be formed on the first frame 78, and recesses may be formed in the second frame 79.

[0369] In the following text, for ease of description, the protrusion and the recess will be referred to as the first groove 791 and the second groove 781, respectively.

[0370] The first groove 791 may include a first extension 7911 extending from the contact surface and a second extension 7912 extending from the end of the first extension 7911.

[0371] The first extension 7911 and the second extension 7912 may have different shapes in a cross section perpendicular to the extension direction of the frame portion 770.

[0372] In a cross-section perpendicular to the protruding direction of the first groove 791, at least a portion of the second extension 7912 may not overlap with the first extension 7911 relative to the protruding direction of the first groove 791. Therefore, even when the first groove 791 and the second groove 781, which are joined together, are subjected to an external force acting in a direction separating them from each other, their easy separation can be prevented.

[0373] Figure 25 (a) shows an example 7912a of a second extension 7912 with a circular shape.

[0374] The second extension 7912 can be formed in a circular shape, with a diameter greater than the width of the first extension 7911.

[0375] Therefore, at least a portion of the extended cross-section of the second extension 7912 can be larger than the extended cross-section of the first extension 7911, thereby preventing the first frame 78 and the second frame 79 from separating.

[0376] Figure 25 (b) shows an example of a second extension 7912 formed as a hook 7912b extending to one side from the end of the first extension 7911.

[0377] In the following text, refer to Figure 25 The direction in which the second extension 7912 bends from the first extension 7911 when the second extension 7912 is formed into a hook shape 7912b will be described.

[0378] Figure 25 A cross-section is shown along the line DD′ that intersects the inner and outer sides of the frame portion 770, which has a closed curve shape. For ease of description, the direction toward the outer side of the frame portion 770 will be referred to as the outward direction R1, and the direction toward the inner side of the frame portion 770 will be referred to as the inward direction R2.

[0379] Figure 26 (a) shows an example in which one of a pair of second extensions 7912 bends outward in the direction R1 from the first extension 7911 and the other second extension 7912 bends in the direction R2 from the first extension 7911.

[0380] When the second extension 7912 bends from the end of the first extension 7911 to face each other, as Figure 26 As shown in (a), the edge of the filter 775 can be prevented from separating from the frame portion 770.

[0381] For example, when the filter screen 775 is pulled in an outward direction R1 or an inward direction R2, which is the direction in which the filter screen 775 separates from the frame portion 770, the second extension 7912, which is arranged in a curved shape, can deform towards the center of the frame portion 770 through the elasticity of the material itself. Therefore, the force at the end of the second extension 7912 that binds the filter screen 775 to the center of the frame portion 770 can be increased, thereby improving the reliability of the filter screen 775's fixation.

[0382] Figure 26 (b) shows an example of a pair of second extensions 7912 bending outward in the direction R1 from the first extension 7911. Figure 26 The second extension 7912 shown in (b) may be advantageous in resisting the tension of the filter 775.

[0383] For example, when the filter screen 775 filters the air inside the roller 3b and receives force at its central portion to transmit tension in the inward direction of the frame portion 770, since the second extension portion 412 is provided in the outward direction R2, the resistance to bending can be maximized while allowing the frame portion 770 to stably support the filter screen 775.

[0384] In this case, when the first groove 791 is formed as a protrusion on the second frame 79, the second extension 7912 supports the filter screen 775, which is subjected to forces toward the downstream side and toward the upstream side, thereby improving the reliability of the connection between the filter screen 775 and the frame 770.

[0385] Figure 27 An example of frame section 770 is shown. Figure 27 (a) shows a view of the second frame 79 as seen from the front side of the filter pipe 73a, and Figure 27 (b) shows a view of the first frame 78 connected to the second frame 79.

[0386] exist Figure 27 In the example, the frame portion 770 has a rectangular shape, in which all interior angles are right angles, and a pair of opposite long sides are longer than another pair of opposite short sides.

[0387] For ease of description, in the following text, the length of a pair of relatively longer opposite sides will be referred to as the long side D1, and the length of a pair of relatively shorter opposite sides will be referred to as the short side D2.

[0388] In the second frame 79, the connecting magnet receiving groove 792 can be formed in the extrusion operation S1, and the connecting magnet 776 can be accommodated in the corresponding side of the opening 350 that has undergone the cutting operation S2, depending on the length of the corresponding side of the opening 350.

[0389] When the ends of the respective sides of the connecting magnet are fused together, a predetermined fusion gap G can be formed between each fused end and the connecting magnet 776, so that the fusion is not obstructed by the connecting magnet 776 and the fusion connection force is not reduced. Therefore, the fusion gap G can be formed such that at least a portion of it overlaps with the fusion line L1.

[0390] The fusion gap G can be formed at each corner of the second frame 79, and the connecting magnet 776 can be inserted into the second frame 79 so that it is discontinuous at the corner.

[0391] When the filter screen 775 and the first frame 78 are connected to the second frame 79, as follows: Figure 27 As shown in (b), the filter 775 can be compressed in the direction of airflow, while its edges are tensioned by the frame portion 770. Therefore, the frame portion 770 can withstand tension in the inward direction R2.

[0392] When the frame portion 770 is subjected to tension in the inward direction R2, the central portion of the corresponding side, whose rigidity is reinforced by the connecting magnet 776, can resist this tension. However, without resisting the tension of the filter screen 775, the portion corresponding to the fusion gap G can be deformed, in which the rigidity is reduced because the connecting magnet receiving groove 792 and the connecting magnet 776 are not accommodated. Therefore, the frame portion 770 can be deformed to bend or fold relative to the corner forming the fusion gap G.

[0393] Furthermore, when twisting occurs on each side due to the tension of the filter 775, the twist angle 7701 formed in the long side D1 can be greater than the twist angle 7702 formed in the short side D2, because the twist angle is proportional to the length of the side.

[0394] Therefore, the long side D1 can be twisted, and the frame portion 770 can be deformed in a folding manner relative to its pair of opposite corners.

[0395] Figure 28 An example of shape-retaining member 778 is shown. Figure 28 (a) shows a view of the shape-retaining member 778 as seen from the front side of the filter pipe 73a, and Figure 27 (b) shows a cross-sectional view taken along the line FF′ that intersects the inner and outer sides of the shape retaining member 778 that forms a closed curve.

[0396] The shape-retaining member 778 can be arranged in the shape of a round rod extending along the periphery of the pipe filter 77.

[0397] The shape-retaining member 778 may be formed of a metallic material and may include at least one weld line L2, which is produced when its end is welded to form a closed curve.

[0398] Weld lines L2 may not be clearly distinguishable by appearance. However, weld lines L2 can be identified by the physically uneven protruding shape caused by welding on their surface, by traces formed by uneven polishing of the surface, by traces discolored by heat treatment, or by traces formed by surface treatment.

[0399] Even when the weld line L2 is not visually visible, it can be distinguished from other parts by slight inconsistencies or differences in its density or thickness. The weld line L2 only needs to be identified by someone skilled in the art based on the characteristics produced by the weld.

[0400] In the shape-retaining member 778, the welded joint connected to the weld line L2 can have lower strength than other parts. Therefore, the weld line L2 can be provided at a point that does not overlap with the fusion gap G or the fusion line L1 to avoid deformation concentration on the fusion gap G or the fusion line L1.

[0401] When the frame portion 770 has a rectangular shape in which all interior angles are right angles and one pair of opposite sides are longer than the other pair of opposite sides, the welding line L2 can be formed in the portion of each side of the frame portion 770 that is inserted into the short side D2.

[0402] As described above, when twisting occurs on each side due to the tension of the filter screen 775, the twist angle 7701 formed in the long side D1 can be greater than the twist angle 7702 formed in the short side D2, because the twist angle is proportional to the length of the side. Therefore, when the weld line L2 is formed in the short side D2, a large load is not applied to the relatively weak weld line L2. Thus, the reliability of the strength of the shape-retaining member 778 can be improved.

[0403] When the opening 350 is formed into a polygonal shape, the corner 779 of the shape retaining member 778 can be bent to have a radius R. Therefore, when an external force is applied to the shape retaining member 778, the load can be prevented from being concentrated on the corner 779, thereby preventing breakage.

[0404] The shape-retaining member 778 can be formed of a material having a stiffness sufficient to withstand the tension of the filter 775 and a torsional stiffness high enough to resist the torsional moment generated in the frame portion 770 due to the tension exerted on the frame portion 770 by the filter 775. Therefore, as described above, the distortion of the long side D1 can prevent the frame portion 770 from deforming relative to its pair of opposite angles in a folded manner.

[0405] Figure 29The assembly of the frame 770, filter 775, and shape-retaining member 778 is shown.

[0406] The shape-retaining member 778 can be inserted into the central portion of the frame portion 770. That is, the length t1 from the contact surface P of the first frame 78 to the end of the first frame 78 extending therefrom and the length t2 from the contact surface P of the second frame 79 to the end of the second frame 79 extending therefrom can be equal to each other, and the depths of the shape-retaining member receiving grooves 784 and 794 from the respective contact surfaces P can also be equal to each other.

[0407] That is, the distance from the shape retaining member 778 to the outside of the first frame 78 and the distance from the shape retaining member 778 to the outside of the second frame 79 can be set to be equal.

[0408] When the frame portion 770 is formed of the same material and the shape-keeping member 778 extends across the center of the corresponding side of the frame portion 770, deformation of the frame portion 770 can be prevented most effectively, and production and design can be simplified.

[0409] The pipeline filter 77 can be formed by assembly operation S4, in which filter screen 775 is stacked on first frame 78, shape retaining member 778 is inserted on filter screen 775, and second frame 79 and first frame 78 are connected when the protrusion (first groove 791) of second frame 79 is fitted into the recess (second groove 781) of first frame 78.

[0410] When a first groove 791 with a protruding shape is formed on the second frame 79 and a second groove 781 with a recessed shape is formed on the first frame 78, the filter screen can be inserted and fixed between the first frame 78 and the shape-retaining member 778. When an external force is applied to the filter screen 775 in the downstream direction due to airflow, the grooves 781 and 791 of the frame portion 770 and the shape-retaining member 778 can support the filter screen 775 in the upstream direction, and thus the filter screen 775 can be stably fixed to the frame portion 770 without excessive tension.

[0411] Figure 30 A front view of the pipe filter 77 is shown, viewed from the front side of the opening 350.

[0412] The filter conduit 73a may include a magnetic sensor 314, which will be described later, and is configured to sense magnetic field strength, etc. Therefore, the frame portion 770 may accommodate a magnetic field source 777 from which the magnetic sensor 314 detects magnetic signals, thereby sensing the attachment of the conduit filter 77 to the filter conduit 73a.

[0413] The handle 783 and the magnetic field source 777 may be formed on at least a portion of the frame portion 770 or housed in at least a portion of the frame portion 770. Figure 30 An example is shown in which the magnetic field source 777 is housed in the central portion of the upper side of the frame portion 770 and the handle 783 is located on the left side of the frame portion 770.

[0414] based on Figure 30 , Figures 31 to 33 A cross-section of the frame portion 770 is shown, extending from the inside to the outside of the frame portion 770. Figure 31 The diagram shows a cross-section taken along line A-A', where no handle 783 or magnetic field source 777 is formed. Figure 32 A cross-section taken along line B-B' is shown, in which the magnetic field source 777 is contained, and Figure 33 A cross-section taken along line C-C' is shown, including the handle 783. These are merely examples of this disclosure, and the handle 783 and the magnetic field source 777 may not be provided, or they may be arranged to overlap each other.

[0415] Figure 30 The diagram shows a second frame 79 in which a connecting magnet 776 is housed and a first groove 791 protrudes from the contact surface P, a shape-retaining member 778 stacked on the second frame 79, a filter 775 stacked on the shape-retaining member 778, and a first frame 78 stacked on the filter 775 and having a second groove 781 recessed from the contact surface P.

[0416] The frame portion 770 can be connected by the engagement of the first groove portion 791 and the second groove portion 781, and the filter screen 775 can be fixed by the pressure applied by the shape retaining member 778 and the frame portion 770.

[0417] This is merely one implementation. The protruding and recessed directions of the first groove 791 and the second groove 781 can be reversed at their respective contact surfaces P, and the filter screen 775 can be secured by the pressure applied by the shape-retaining member 778 and the second frame 79.

[0418] When the filter 775 is pressed firmly by the frame 770 and the shape-retaining member 778, the duct filter 77 can convey a visual impression of solid, commercial-grade durability to the user.

[0419] Figure 32 A view of a magnetic field source 777 fixed to a second frame 79 is shown. The second frame 79 may include a magnetic field source receiving slot 793 in which the magnetic field source 777 can be housed.

[0420] The magnetic field source receiving groove 793 can replace a part of the first groove 791 and protrude from the contact surface P to be fitted into the second groove 781 of the first frame 78.

[0421] Therefore, even when the second frame 79 is compressed during batch processing, the magnetic field source 777 can be accommodated through post-processing operations (e.g., cutting only a portion of the first groove 791). This reduces production costs.

[0422] Figure 33 A view of the handle 783 and sealing rib 782 disposed on the first frame 78 is shown.

[0423] As described above, the protrusion angle and formation position of the handle 783 can be changed according to the position of the set pipe filter 77.

[0424] The handle 783 can be arranged so that a user of average height can grip the handle 783 within the range of arm movement without standing on tiptoe or bending over.

[0425] For example, when the lower part of the duct filter 77 is close to the ground, the handle 783 can be located on the upper part or side of the duct filter 77 for user accessibility, and the protrusion angle can be formed such that the handle 783 is offset toward the center of the filter duct 73a to prevent collision with the inner surface of the filter duct 73a in which the duct filter 77 is housed.

[0426] For ease of production, the handle 783 can be formed separately from and attached to the first frame 78.

[0427] As described above, the angle at which the sealing rib 782 protrudes from the outer edge of the first frame 78 can be greater than the angle formed between the inner surface of the filter pipe 73a on which the filter pipe 77 is installed and the filter pipe 77. Therefore, the sealing rib 782 and the inner surface of the pipe body 310 can naturally come into contact with and press against each other, thereby effectively blocking the airflow.

[0428] The sealing rib 782 may be provided only on a portion of the first frame 78. For ease of manufacturing, the sealing rib 782 may be formed separately from and attached to the first frame 78.

[0429] It will be apparent to those skilled in the art that various modifications and variations may be made to this disclosure without departing from its spirit and scope. Therefore, this disclosure is intended to cover such modifications and variations as long as they fall within the scope of the appended claims and their equivalents.
