Description

Technical Field

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

[0002] International application WO2019 / 049697 discloses a washing machine (clothes handling device) with a centrifugal separation unit 94. For example... Figure 1 As shown, the main working principle of this washing machine is as follows: During the washing stage, clothes are put into the washing tub 92. After the washing machine is run until the washing water reaches the specified water level, the circulation pump 93 runs, sending the washing water from the separation section inlet 941 into the centrifugal separation section 94 through the first switching valve 95, the circulation pump 93, and the second switching valve 96. After the centrifugal separation section 94 separates the foreign matter contained in the washing water, the washing water is sent back to the outer tub 91 from the separation section outlet 942 through the third switching valve 97. The above circulation action is repeated until the drainage stage. During the drainage stage, the circulation pump 93 runs, sending the washing water from the separation section outlet 942 into the centrifugal separation section 94 through the first switching valve 95, the circulation pump 93, the second switching valve 96, and the third switching valve 97 to rinse the centrifugal separation section 94, thereby performing the rinsing action. The washing water after rinsing the centrifugal separation section 94 is discharged from the washing machine through the first on / off valve 98 and the second on / off valve 99.

[0003] However, in the aforementioned washing machine (clothes handling device), the water circuit design is complex, requiring the installation of a circulation pump, multiple switching valves, and on / off valves. This not only increases manufacturing costs but also makes the control process during operation complex and prone to malfunctions. Summary of the Invention

[0004] The problem the invention aims to solve

[0005] This disclosure was made in view of the above-mentioned situation, and its purpose is to provide a garment handling device that simplifies the waterway design.

[0006] Solution for solving the problem

[0007] To achieve the above objectives, the first technical solution of this disclosure provides a garment processing device, comprising: an outer tank disposed within the outer casing of the garment processing device; a washing tank rotatably disposed within the outer tank; a centrifugal separation section for separating foreign matter contained in the washing water within the outer tank; and a water distribution structure comprising a housing having an inner cavity, the housing having an inlet, a circulation outlet, and a rinsing outlet respectively communicating with the inner cavity. The garment processing device includes a circulation water path and a rinsing water path. In the circulation water path, the washing water in the outer tank flows into the water distribution structure from the inlet and into the centrifugal separation section from the circulation outlet. After the centrifugal separation section centrifuges and separates the foreign matter contained in the washing water, the water returns to the outer tank. In the rinsing water path, the washing water in the outer tank flows into the water distribution structure from the inlet and into the centrifugal separation section from the rinsing outlet to rinse the centrifugal separation section, and then returns to the water distribution structure.

[0008] According to the first technical solution, by setting up a water distribution structure and making the circulating water path and the flushing water path share the same water distribution structure, the water path design can be simplified, and switching valves and on / off valves can be reduced or eliminated. This helps to reduce manufacturing costs and simplifies the control process during operation. In addition, by separating the circulating water path and the flushing water path at the water distribution structure, different designs can be made for the circulating water path and the flushing water path as needed. For example, by adding different filtration sections to the circulating water path and the flushing water path, different foreign matter filtration requirements can be met.

[0009] The second technical solution is based on the clothing treatment device of the first technical solution, wherein the housing is provided with a drain outlet communicating with the inner cavity, and the clothing treatment device includes a drainage channel, in which washing water in the outer tank flows into the water distribution structure from the water inlet and is discharged to the outside of the clothing treatment device from the drain outlet.

[0010] According to the second technical solution, by making the circulating water path, flushing water path and drainage water path share the same water distribution structure, the water path design can be further simplified.

[0011] The third technical solution is based on the clothing treatment device of the first technical solution, wherein the water distribution structure includes a circulating filter section, the circulating filter section is assembled in the inner cavity, and in the circulating water path, the washing water flowing into the water distribution structure from the water inlet is filtered by the circulating filter section and then flows into the centrifugal separation section from the circulating water outlet.

[0012] According to the third technical solution, by using a circulating filter to filter foreign objects in the washing water before using the centrifugal separation unit, larger foreign objects (such as buttons, coins, etc.) can be filtered before the centrifugal separation unit, preventing them from entering the centrifugal separation unit and causing blockages at the separation unit's inlet or outlet, thus ensuring the normal operation of the centrifugal separation unit. Furthermore, the circulating water circuit is used to recycle the washing water in the outer tank. Due to lint blockage, the washing water circulation process can be affected, especially when the circulating water pipes are narrow (e.g., when the washing water returns to the outer tank via spraying). Lint can easily clog the pipes (spray nozzles), leading to insufficient circulation and a potential decrease in the washing effect of the clothes. However, by setting up a circulating filter, the workload of the centrifugal separation unit can be reduced, and foreign objects in the washing water can be separated more effectively, thus avoiding blockages in the circulating water circuit and improving the washing effect of the clothes processing device.

[0013] The fourth technical solution is based on the clothing processing device of the first technical solution. The centrifugal separation section includes: an outer drum; a rotating drum that is rotatably disposed inside the outer drum; and a driving device for driving the rotating drum to rotate. The clothing processing device can perform a cyclic action. In the cyclic action, the driving force of the driving device is used to make the washing water in the outer tank circulate through the circulating water path. Furthermore, when the washing water flows through the centrifugal separation section, foreign matter contained in the washing water is centrifuged and separated.

[0014] According to the fourth technical solution, the washing water in the outer tank is circulated through the circulating water path by using the driving force of the drive device during the circulation operation. Therefore, when performing the circulation operation, there is no need to use a circulation pump to provide power to the washing water, which can eliminate the need for a circulation pump, simplify the water path structure and reduce manufacturing costs.

[0015] The fifth technical solution is based on the clothing processing device of the second technical solution. The water distribution structure is equipped with a pump, and the clothing processing device can perform a rinsing action. In the rinsing action, the driving force of the pump is used to make the washing water in the outer tank rinse the centrifugal separation section through the rinsing water path and return to the water distribution structure.

[0016] According to the fifth technical solution, by using a pump to power the washing water in the rinsing water path, it is easier to flush away foreign matter attached to the centrifugal separation section, thereby improving the rinsing effect.

[0017] The sixth technical solution is based on the clothing processing device of the fifth technical solution. The clothing processing device is capable of performing a drainage action. In the drainage action, the driving force of the pump is used to discharge the washing water in the outer tank to the outside of the clothing processing device through the drainage water passage. The clothing processing device performs the rinsing action and the drainage action simultaneously by making the pump work.

[0018] According to the sixth technical solution, by using a single pump to power both the washing water in the rinsing circuit and the washing water in the drain circuit, separate pumps for the rinsing and drain circuits are eliminated, simplifying the water circuit design and reducing manufacturing costs. Furthermore, by simultaneously operating the pump to perform rinsing and draining actions, the washing time of the garment processing device is shortened, improving its efficiency.

[0019] The seventh technical solution is, based on the clothing processing device of the fifth technical solution, that the clothing processing device is capable of performing a drainage action. In the drainage action, the driving force of the pump is used to discharge the washing water in the outer tank to the outside of the clothing processing device through the drainage water passage. The start time of the rinsing action is earlier than the start time of the drainage action.

[0020] According to the seventh technical solution, by using a single pump to power both the washing water in the rinsing water path and the washing water in the drainage water path, it is unnecessary to install separate pumps for the rinsing and drainage water paths, thus simplifying the water path design and reducing manufacturing costs. Furthermore, by starting the rinsing action earlier than the drainage action, the weakening of the washing water momentum in the rinsing water path due to the diversion of washing water to the drainage water path can be avoided, thereby enhancing the rinsing effect on the centrifugal separation section.

[0021] The eighth technical solution is, based on the clothing processing device of the fifth technical solution, that the rinsing outlet and the drain outlet are closer to the pump than the inlet and the circulation outlet.

[0022] According to the eighth technical solution, by making the flushing outlet and drain outlet closer to the pump than the inlet and circulation outlet, a single pump can be used to power the washing water in the flushing water path and the washing water in the drain water path.

[0023] The ninth technical solution is based on the clothing treatment device of the eighth technical solution, wherein the rinsing outlet and the drain outlet are arranged parallel to each other.

[0024] According to the ninth technical solution, by setting the flushing outlet and the drain outlet parallel to each other, it is easier to form the flushing outlet and the drain outlet simultaneously through casting.

[0025] The tenth technical solution is based on the clothing treatment device of the eighth technical solution, wherein the drain outlet is arranged radially along the impeller of the pump.

[0026] According to the tenth technical solution, by setting the drain outlet along the radial direction of the pump impeller, it can be ensured that the flow rate of the washing water flowing through the drain outlet does not change significantly whether the impeller is rotating forward or backward. Thus, the pump can be effectively used to provide power for the washing water in the drainage path.

[0027] The eleventh technical solution is based on the clothing treatment device of any of the first to tenth technical solutions, wherein the housing is provided with a drain outlet communicating with the inner cavity, the clothing treatment device includes a drainage water path, in which the washing water in the outer tank flows into the water distribution structure from the water inlet and is discharged to the outside of the clothing treatment device from the drain outlet, and the washing water in the rinsing water path after rinsing the centrifugal separation section returns to the water distribution structure through the circulation outlet and is discharged to the outside of the clothing treatment device through the drainage water path.

[0028] According to the eleventh technical solution, by sharing a water distribution structure among the circulating water circuit, rinsing water circuit, and drainage water circuit, and by allowing the washing water after rinsing the centrifugal separation section to be discharged to the outside of the garment processing device through the drainage water circuit, there is no need to set up a separate pipeline for discharging the washing water after rinsing the centrifugal separation section to the outside of the garment processing device, thereby further simplifying the water circuit design.

[0029] The twelfth technical solution is that, based on the clothing processing device of any of the fifth to tenth technical solutions, the clothing processing device further includes a control unit, which controls the clothing processing device to perform at least one of a circulation action, a rinsing action, and a draining action, so that the washing water in the outer tank flows through the corresponding water path of the circulation water path, the rinsing water path, and the draining water path respectively. When the clothing processing device performs the circulation action, the pump does not work, and when the clothing processing device performs at least one of the rinsing action and the draining action, the pump works.

[0030] According to the twelfth technical solution, by keeping the pump inactive during the cyclic operation, the problem of foreign matter gradually accumulating inside the pump and causing pump blockage during prolonged cyclic operation can be effectively avoided. Furthermore, by operating the pump during at least one of the flushing and draining operations, the pump can provide power to the washing water in the flushing water path and the washing water in the draining water path.

[0031] The thirteenth technical solution is, based on the clothing processing device of the fourth technical solution, that when the clothing processing device performs the cyclic action, the rotating drum rotates in any direction under the drive of the driving device.

[0032] According to the thirteenth technical solution, by using the drive device to rotate the rotating drum in any direction during the cyclic action, it is beneficial to centrifuge the separation of foreign matter in the washing water, and the driving force of the drive device can be effectively used to make the washing water in the outer tank circulate through the circulating water path.

[0033] The fourteenth technical solution is based on the clothing processing device of the twelfth technical solution, wherein the centrifugal separation section includes: an outer cylinder; a rotating cylinder disposed rotatably inside the outer cylinder; and a driving device for driving the rotating cylinder to rotate. When the clothing processing device performs the rinsing action, the rotating cylinder rotates intermittently in the forward direction, intermittently in the reverse direction, or alternately in both directions under the drive of the driving device.

[0034] According to the fourteenth technical solution, by using the drive device to make the rotating drum rotate intermittently in the forward direction, intermittently in the reverse direction, or alternately in both directions during the rinsing action, it is beneficial to shake off foreign matter attached to the centrifugal separation section and improve the rinsing effect.

Detailed Implementation

[0064] The garment handling apparatus disclosed herein may be, for example, a washing machine, a washer-dryer, etc., and as a typical example, it may be a front-loading washing machine, a front-loading washer-dryer, etc. Next, various embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0065] 1. First Implementation Method

[0066] like Figure 2 As shown, the clothing processing device of the first embodiment includes an outer tank 1, a washing tank 2, a water separation structure 3, and a centrifugal separation unit 4.

[0067] The outer tub 1 and the washing tub 2 are, for example, formed into a bottomed cylindrical shape. The outer tub 1 is housed within the outer casing 100 of the garment handling device, and the washing tub 2 is rotatably disposed within the outer tub 1. Specifically, the outer tub 1 is elastically supported within the outer casing 100, for example, by means of multiple suspension structures (not shown). A motor 14 is provided on the outside of the outer tub 1, and the washing tub 2 is capable of rotating about a rotation axis under the drive of the motor 14. The motor 14 can be, for example, a known structure such as a brushless DC motor. Furthermore, the washing tub 2 is provided with an inlet (not shown) for loading and unloading laundry and other laundry items.

[0068] In addition, the outer tank 1 is connected to an external faucet via a hose or the like, so that washing water for washing clothes can be supplied into the outer tank 1. A number of small holes (not shown) are provided on the peripheral wall of the washing tank 2, through which washing water in the outer tank 1 can flow into the washing tank 2, and vice versa.

[0069] In addition, the outer tank 1 includes a first outer tank outlet 11 and a second outer tank outlet 12. The first outer tank outlet 11 and the second outer tank outlet 12 are independently located on the lower side of the outer tank 1, and the washing water in the outer tank 1 can flow out to the outside of the outer tank 1 through the first outer tank outlet 11 and the second outer tank outlet 12.

[0070] The water distribution structure 3 includes a generally cylindrical shell 31. The shell 31 has an inner cavity C and is provided with an inlet P1, a circulating outlet P2 and a drain P5 that are respectively connected to the inner cavity C.

[0071] Furthermore, the water distribution structure 3 also includes a circulating filter section F1, which is assembled in the inner cavity C. This circulating filter section F1 divides the inner cavity C into a first chamber C1 and a second chamber C2 along the axial direction of the housing 31. The first chamber C1 and the second chamber C2 are arranged along the axial direction of the housing 31. The inlet P1 and outlet P5 are respectively connected to the first chamber C1, and the circulating outlet P2 is connected to the second chamber C2. Here, "the inlet P1 and outlet P5 are respectively connected to the first chamber C1, and the circulating outlet P2 is connected to the second chamber C2" means that the inlet P1 and outlet P5 are respectively located on the peripheral wall of the housing 31 forming the first chamber C1, and the circulating outlet P2 is located on the peripheral wall of the housing 31 forming the second chamber C2.

[0072] In addition, the water distribution structure 3 also includes a drainage filter section F2, which is assembled in the first chamber C1.

[0073] The centrifugal separation unit 4 is used to separate foreign matter contained in the washing water in the outer tank 1. Specifically, the centrifugal separation unit 4 includes: an outer cylinder 41, which forms the outer contour of the centrifugal separation unit 4; a rotating cylinder 42, which is a hollow cylinder and is rotatably disposed inside the outer cylinder 41; and a drive device 43, which is used to drive the rotating cylinder 42 to rotate, for example, a known structure such as a brushless DC motor can be used.

[0074] Additionally, the centrifugal separation section 4 includes a separation section inlet 44, a separation section outlet 45, and a separation section flushing port 46, all located on the outer cylinder 41. The separation section inlet 44 is located on the lower side of the outer cylinder 41. The separation section outlet 45 and the separation section flushing port 46 are independently located on the upper side of the outer cylinder 41. The second outer tank outlet 12 is higher than the separation section flushing port 46.

[0075] Wash water after washing clothes usually contains various foreign objects such as lint, sand, hair, and keratin. When separating foreign objects from the wash water, the rotating drum 42 is driven to rotate by the drive device 43, so that the wash water flows from the separation section inlet 44 into the centrifugal separation section 4. During the flow of the wash water through the rotating drum 42, the wash water swirls while flowing through it. The foreign objects contained in the wash water move towards the inner circumference of the rotating drum 42 due to centrifugal force. Thus, the wash water is separated from the foreign objects. Afterward, the wash water flows out of the centrifugal separation section 4 from the separation section outlet 45.

[0076] In addition, when rinsing the foreign matter accumulated in the centrifugal separation section 4, the washing water flows into the centrifugal separation section 4 from the separation section rinsing port 46, and flows out of the centrifugal separation section 4 from the separation section inlet 44 after rinsing the centrifugal separation section 4.

[0077] The garment processing device also includes a first pipe 51, a second pipe 52, a third pipe 53, a fourth pipe 54, and a fifth pipe 6. The first pipe 51 connects the first outer tank outlet 11 of the outer tank 1 to the inlet P1 of the water distribution structure 3. The second pipe 52 connects the second outer tank outlet 12 of the outer tank 1 to the rinsing port 46 of the centrifugal separation section 4. One end of the third pipe 53 is connected to the separation section outlet 45 of the centrifugal separation section 4, and the other end extends into the interior of the outer tank 1 from the upper side. One end of the fourth pipe 54 is connected to the drain outlet P5 of the water distribution structure 3, and the other end extends to the outside of the garment processing device. The fifth pipe 6 connects the circulation outlet P2 of the water distribution structure 3 to the separation section inlet 44 of the centrifugal separation section 4.

[0078] Therefore, the garment handling device includes a circulating water path L1, a rinsing water path L2, and a drain water path L3.

[0079] In the circulating water circuit L1, the washing water in the outer tank 1 flows from the first outer tank outlet 11 through the first pipe 51 from the inlet P1 into the first chamber C1 of the water distribution structure 3. After being filtered by the circulating filter F1, it enters the second chamber C2. Then, the washing water flows from the circulating outlet P2 through the fifth pipe 6 from the separation section inlet 44 into the centrifugal separation section 4. In the centrifugal separation section 4, foreign matter contained in the washing water is centrifuged and separated. Then, the washing water returns to the outer tank 1 from the separation section outlet 45 through the third pipe 53.

[0080] In the rinsing water path L2, since the outlet 12 of the second outer tank is higher than the rinsing port 46 of the separation section, the washing water in the outer tank 1 flows from the outlet 12 of the second outer tank through the second pipe 52 from the rinsing port 46 of the separation section to the centrifugal separation section 4 to rinse the centrifugal separation section 4. The washing water after rinsing the centrifugal separation section 4 flows from the inlet 44 of the separation section through the fifth pipe 6 from the circulation outlet P2 to the second chamber C2 of the water distribution structure 3. Then the washing water flows from the second chamber C2 through the circulation filter section F1 into the first chamber C1.

[0081] In the drainage water path L3, the washing water in the outer tank 1 flows from the first outer tank outlet 11 through the first pipe 51 from the inlet P1 into the first chamber C1 of the water distribution structure 3. After being filtered by the drainage filter F2, it is discharged from the drain outlet P5 through the fourth pipe 54 to the outside of the garment processing device. In addition, the washing water in the rinsing water path L2, after rinsing the centrifugal separation section 4 and flowing into the first chamber C1, is also filtered by the drainage filter F2 and discharged from the drain outlet P5 through the fourth pipe 54 to the outside of the garment processing device.

[0082] The operation of the garment handling device configured as described above will be explained below.

[0083] When washing clothes, the garment handling device first performs a washing process, which involves supplying wash water containing detergent to the outer tub 1 and using the rotation of the washing tub 2 to pound and wash the clothes to remove dirt. Next, a rinsing process is performed, including, for example, a first intermediate spin-drying process, a first rinsing process, a second intermediate spin-drying process, and a second rinsing process. Finally, a spin-drying process is performed.

[0084] Furthermore, the garment handling device is capable of performing circulation, rinsing, and draining operations. In other words, the washing water treatment method performed by the garment handling device includes circulation, rinsing, and draining operations. Specifically, the garment handling device also has a control unit (not shown) that controls the garment handling device to perform at least one of the circulation, rinsing, and draining operations, so that the washing water in the outer tank 1 flows through the corresponding water passages in the circulation water passage L1, rinsing water passage L2, and draining water passage L3, respectively.

[0085] In at least one of the washing, first rinsing, and second rinsing processes (e.g., in the washing process), the garment handling device performs a cyclic operation. During this cyclic operation, the washing water in the outer tank 1 is circulated through the circulation water path L1 by the driving force of the drive device 43, and foreign matter contained in the washing water is centrifuged and separated as it flows through the centrifugal separator 4. At this time, driven by the drive device 43, the rotating drum 42 rotates in any direction, thereby providing power to the washing water and causing it to circulate through the circulation water path L1.

[0086] In the first intermediate dehydration step, the second intermediate dehydration step, and the dehydration step, the garment processing device performs rinsing and draining actions. During the rinsing action, the washing water in the outer tank 1 rinses the centrifugal separator 4 via the rinsing water passage L2. At this time, driven by the drive device 43, the rotating drum 42 rotates intermittently in the forward direction, intermittently in the reverse direction, or alternately in both directions. During the draining action, the washing water in the outer tank 1 is discharged to the outside of the garment processing device via the draining water passage L3. At this time, the washing water in the rinsing water passage L2, after rinsing the centrifugal separator 4 and flowing into the water distribution structure 3, is also discharged to the outside of the garment processing device via the draining water passage L3.

[0087] The specific structure of the garment processing apparatus according to the first embodiment has been described above. An important feature of the garment processing apparatus of the first embodiment is that, in the rinsing water path L2, the outlet 12 of the second outer tank is higher than the rinsing port 46 of the separation section, allowing the washing water in the outer tank 1 to flow from the outlet 12 of the second outer tank through the rinsing port 46 of the separation section into the centrifugal separation section 4 to rinse the centrifugal separation section 4. Appropriate modifications can be made to the structure other than this.

[0088] For example, in the first embodiment, a structure is described in which the first outer tank outlet 11 and the second outer tank outlet 12 are independently provided in the outer tank 1, and the separation section outlet 45 and the separation section flushing port 46 are independently provided in the centrifugal separation section 4, but it is not limited to this.

[0089] like Figure 3 As shown, in a first variation of the first embodiment, the first outer tank outlet 11 also serves as the second outer tank outlet 12. Furthermore, a second pipe 52 branches off midway from the first pipe 51 connected to the first outer tank outlet 11. The first pipe 51 leads to the separation section inlet 44, forming part of the circulating water path L1, while the second pipe 52 leads to the separation section flushing port 46, forming part of the flushing water path L2. A switching valve 55 is provided at the branch of the second pipe 52 from the first pipe 51. The switching valve 55 selectively directs the washing water in the outer tank 1 from the first outer tank outlet 11 to either the portion of the first pipe 51 downstream of the switching valve 55 or the second pipe 52. Furthermore, the first outer tank outlet 11, which also serves as the second outer tank outlet 12, is higher than the separation section flushing port 46, and the branch of the second pipe 52 branching off from the first pipe 51 is higher than the separation section flushing port 46. Therefore, the washing water in the outer tank 1 can also flow from the first outer tank outlet 11 through the separation section flushing port 46 to the centrifugal separation section 4 by its own weight to flush the centrifugal separation section 4.

[0090] like Figure 4 As shown, in a second variation of the first embodiment, the separation section outlet 45 also serves as the separation section rinsing port 46. Furthermore, the second pipe 52, which connects to the second outer tank outlet 12, is connected midway to the third pipe 53, and is connected to the separation section outlet 45 via the third pipe 53. Moreover, since the second outer tank outlet 12 is higher than the separation section outlet 45, which also serves as the separation section rinsing port 46, the washing water in the outer tank 1 can also flow into the centrifugal separation section 4 from the second outer tank outlet 12 via the separation section outlet 45 by its own weight to rinse the centrifugal separation section 4.

[0091] like Figure 5 As shown, in a third variation of the first embodiment, the first outer tank outlet 11 also serves as the second outer tank outlet 12, and the separation section outlet 45 also serves as the separation section rinsing outlet 46. Furthermore, the first outer tank outlet 11, which also serves as the second outer tank outlet 12, is higher than the separation section outlet 45, which also serves as the separation section rinsing outlet 46, and the branch of the second pipe 52 branching off from the first pipe 51 is higher than the separation section outlet 45, which also serves as the separation section rinsing outlet 46. Therefore, the washing water in the outer tank 1 can also flow into the centrifugal separation section 4 from the first outer tank outlet 11 via the separation section outlet 45 by its own weight to rinse the centrifugal separation section 4.

[0092] Furthermore, in the first embodiment, a structure was described in which the washing water after rinsing the centrifugal separation section 4 flows from the separation section inlet 44 into the water distribution structure 3 in the rinsing water path L2, but it is not limited to this. For example, a separate outlet may be provided in the centrifugal separation section 4 for the washing water after rinsing the centrifugal separation section 4 to flow out of the centrifugal separation section 4, and the washing water may be discharged to the outside of the garment processing device by means of other pipelines.

[0093] Furthermore, while the first embodiment describes a garment processing device with a water-dividing structure 3, it is not limited to this. For example, the water-dividing structure 3 may be omitted. In this case, in the circulating water path L1, the first pipe 51 is directly connected to the outlet 11 of the first outer tank and the inlet 44 of the separation section; in the drainage water path L3, the fourth pipe 54 is directly connected to the outlet 11 of the first outer tank, or connected midway to the first pipe 51 connected to the outlet 11 of the first outer tank.

[0094] Furthermore, although not further explained in the first embodiment, an on / off valve can be installed in the fourth pipe 54 of the drainage water path L3 as a drain valve. Additionally, a drain pump can be installed in the fourth pipe 54, which can provide power for the flow of washing water in the rinsing water path L2 and the drainage water path L3. In other words, the statement in this disclosure that "the washing water in the outer tank 1 flows by its own weight from the second outer tank outlet 12 through the separation section rinsing port 46 into the centrifugal separation section 4 to rinse the centrifugal separation section 4" does not exclude the possibility that, in addition to the weight of the washing water itself, a drain pump is also used to power the rinsing washing water.

[0095] 2. Second Implementation Method

[0096] The main difference between the garment handling device of the second embodiment and the first embodiment (especially the second variation of the first embodiment) is that the second pipe 52 is not connected to the second outer tank outlet 12 of the outer tank 1, but is connected to the rinsing outlet P3 of the water distribution structure 3. Hereinafter, refer to... Figures 6 to 16 The garment processing apparatus of the second embodiment will be described, and repeated descriptions of parts common to the first embodiment will be omitted as appropriate.

[0097] like Figures 6 to 8 As shown, the clothing processing device of the second embodiment includes an outer tank 1, a washing tank 2, a water separation structure 3, and a centrifugal separation unit 4.

[0098] The outer tub 1 and the washing tub 2 are, for example, formed into a bottomed cylindrical shape. The outer tub 1 is disposed inside the housing 100 of the garment handling device, and the washing tub 2 is rotatably disposed inside the outer tub 1. In addition, the outer tub 1 includes a first outer tub outlet 11, which is disposed on the lower side of the outer tub 1, and the washing water in the outer tub 1 can flow out to the outside of the outer tub 1 through the first outer tub outlet 11.

[0099] The water distribution structure 3 includes a generally cylindrical shell 31. The shell 31 has an inner cavity C and is provided with an inlet P1, a circulation outlet P2, a flushing outlet (first outlet) P3, and a drain outlet (second outlet) P5 that are respectively connected to the inner cavity C.

[0100] like Figure 9 , Figure 10 As shown, the inlet P1 is located near the center of the housing 31 along its axial direction, and the circulation outlet P2 is located near one end of the housing 31 along its axial direction. The circulation outlet P2 is located on the side opposite to the side where the inlet P1 is located relative to the central axis of the housing 31, and extends in the opposite direction to the extending direction of the inlet P1. The flushing outlet P3 and the drain outlet P5 are located near the other end of the housing 31 along its axial direction, and are arranged close to each other.

[0101] Additionally, a housing cover 33 is provided at one end of the housing 31 in the axial direction, and a pump 32 is provided at the other end of the housing 31 in the axial direction. The housing cover 33 blocks one end opening of the housing 31, and the pump 32 blocks the other end opening of the housing 31.

[0102] like Figure 11 As shown, the pump 32 has an impeller 321. The pump 32 is installed in the housing 31 such that the impeller 321 is inserted into the housing 31, thus the housing 31 serves as the pump casing of the pump 32, and the inner cavity C of the housing 31 (specifically, the fourth chamber C4 described later) serves as the pump chamber of the pump 32. The flushing outlet P3 and the drain outlet P5 are closer to the pump 32 than the inlet P1 and the circulation outlet P2. Specifically, the flushing outlet P3 and the drain outlet P5 are located on the peripheral wall of the housing 31, radially outward from the impeller 321. Furthermore, the flushing outlet P3 and the drain outlet P5 are arranged circumferentially around the housing 31 and are parallel to each other. The drain outlet P5 is arranged radially along the impeller 321. By driving the impeller 321 to rotate circumferentially around the housing 31, water flowing into the housing 31 from the inlet P1 can flow out of the housing 31 from the flushing outlet P3 and / or the drain outlet P5.

[0103] like Figures 9 to 13 As shown, the water distribution structure 3 also includes a circulation filter section F1, a drainage filter section F2, and an outlet filter section F3.

[0104] The circulating filter section F1 is a generally circular plate-shaped filter plate, connected to the housing cover 33 via a first connecting part 331. By installing the housing cover 33 onto the housing 31, the circulating filter section F1 is assembled into the inner cavity C. At this time, the outer peripheral surface of the circulating filter section F1 abuts against the inner peripheral surface of the housing 31, or against a step or similar portion provided on the inner peripheral surface of the housing 31. Furthermore, the circulating filter section F1 is located between the inlet P1 and the circulating outlet P2 along the axial direction of the housing 31. Thus, the circulating filter section F1 divides the inner cavity C into a first chamber C1 and a second chamber C2, which are arranged along the axial direction of the housing 31. The inlet P1, the flushing outlet P3, and the drain outlet P5 are connected to the first chamber C1, and the circulating outlet P2 is connected to the second chamber C2. Here, "the inlet P1, the flushing outlet P3, and the drain outlet P5 are respectively connected to the first chamber C1, and the circulation outlet P2 is connected to the second chamber C2" means that the inlet P1, the flushing outlet P3, and the drain outlet P5 are respectively located on the peripheral wall of the housing 31 forming the first chamber C1, and the circulation outlet P2 is located on the peripheral wall of the housing 31 forming the second chamber C2.

[0105] Furthermore, a partition 314 is provided inside the housing 31, which divides the inner cavity C (specifically the first chamber C1) axially into a third chamber (inlet chamber) C3 and a fourth chamber (outlet chamber) C4. A connecting port 315 is provided on the partition 314, through which the third chamber C3 and the fourth chamber C4 are connected. In addition, the inlet P1 is connected to the third chamber C3, and the flushing outlet P3 and the outlet P5 are respectively connected to the fourth chamber C4. The impeller 321 is located in the fourth chamber C4. Here, "the inlet P1 is connected to the third chamber C3, and the flushing outlet P3 and the outlet P5 are respectively connected to the fourth chamber C4" means that the inlet P1 is located on the peripheral wall of the housing 31 forming the third chamber C3, and the flushing outlet P3 and the outlet P5 are respectively located on the peripheral wall of the housing 31 forming the fourth chamber C4.

[0106] The drain filter F2 is assembled in the first chamber C1 (specifically, the third chamber C3), and is generally conical in shape, having a tapered guide surface that gradually widens as it approaches the connecting port 315. This drain filter F2 is connected to the circulation filter F1 via a second connecting part 332. The drain filter F2 is assembled in the first chamber C1 by installing the housing cover 33 onto the housing 31. At this time, a predetermined radial filtration gap exists between the tapered guide surface of the circulation filter F1 and the inner circumferential surface of the housing 31. Additionally, an axial filtration gap is provided between the drain filter F2 and the partition 314. This prevents larger foreign objects such as buttons and coins from moving from the third chamber C3 to the fourth chamber C4 with the flow of washing water. The washing water in the third chamber C3, after being filtered by the drain filter F2, flows into the fourth chamber C4 through the connecting port 315.

[0107] The outlet filter F3 is located in the fourth chamber C4. It is installed on the inner circumferential surface of the peripheral wall of the housing 31, corresponding to the flushing outlet P3, on the radially outer side of the impeller 321. The washing water in the fourth chamber C4 is filtered by the outlet filter F3 and then flows out of the housing 31 from the flushing outlet P3. Specifically, the inner circumferential surface of the peripheral wall of the housing 31 is provided with a groove 311 for inserting the outlet filter F3. The groove 311 has guide recesses 312 on both sides in the circumferential direction, and the outlet filter F3 has guide protrusions 313 on both sides in the circumferential direction. By inserting the guide protrusions 313 along the axial direction of the housing 31 into the guide recesses 312, the outlet filter F3 is inserted and installed in the groove 311. At this time, the outlet filter F3 extends along a circle concentric with the impeller 321, and the inner surface of the outlet filter F3 is approximately flush with the inner circumferential surface of the peripheral wall of the housing 31 at the fourth chamber C4. Furthermore, the end of the water outlet filter unit F3 that is inserted into the slide groove 311 along the axial direction of the housing 31 is provided with a locking hook portion 316, and a locking recess portion 317 is provided at the bottom of the slide groove 311 at a position corresponding to the locking hook portion 316. When the water outlet filter unit F3 is inserted into the slide groove 311, the locking hook portion 316 engages with the locking recess portion 317, thereby preventing the water outlet filter unit F3 from shaking or falling off in the axial direction of the housing 31.

[0108] like Figures 7 to 8 , Figures 14 to 16 As shown, the centrifugal separation unit 4 is used to separate foreign matter contained in the washing water in the outer tank 1. Specifically, the centrifugal separation unit 4 includes: an outer cylinder 41, which forms the outer outline of the centrifugal separation unit 4; a base 47 on which the outer cylinder 41 is mounted; a rotating cylinder 42, which is a hollow cylinder and is rotatably disposed inside the outer cylinder 41; and a drive device 43 for driving the rotating cylinder 42 to rotate, such as a known structure such as a brushless DC motor.

[0109] In addition, the outer cylinder 41 is composed of an upper part 411 and a lower part 412. The centrifugal separation section 4 includes a separation section inlet 44 and a separation section outlet 45. The separation section inlet 44 is located in the lower part 412 of the outer cylinder, and the separation section outlet 45 is located in the upper part 411 of the outer cylinder.

[0110] In addition, the garment processing device includes a connecting structure 7, which includes: a base 71 that can be connected to the outlet 45 of the separation section; a pipeline support 72 for supporting the pipeline described later; and a connecting plate 73 disposed on the base 71 and connecting the base 71 and the pipeline support 72.

[0111] The base 71 is a bottomed cylindrical shape with one open end, and the open end of the base 71 is connected to the outlet 45 of the separation section. The base 71 has an outer peripheral wall 711, a bottom wall 712 that seals the other end of the outer peripheral wall 711, and an inner peripheral wall 713 that protrudes from the inner surface of the bottom wall 712 toward the interior of the base 71. The inner peripheral wall 713 is concentric with the outer peripheral wall 711. The outlet 45 of the separation section is connected to the base 71 by inserting the tube portion of the outlet 45 between the outer peripheral wall 711 and the inner peripheral wall 713. In addition, a first connection port 74 and a second connection port 75 communicating with the space inside the base 71 are provided on the outer surface of the bottom wall 712.

[0112] The pipe support 72 is used to support at least a portion of the pipes in the circulating water path L1, the flushing water path L2, or the drainage water path L3 (described later). The pipe support 72 has two opposing spring clips 720 located at the ends of the connecting plate 73. The pipe is supported by engaging the pipe between the two spring clips 720. The pipe support 72 supports the pipe at a position higher than the centrifugal separator 4. Furthermore, the connecting plate 73 can also be configured to have an adjustable length.

[0113] like Figures 6 to 8 As shown, the garment processing device also includes a first pipe 51, a second pipe 52, a third pipe 53, a fourth pipe 54, and a fifth pipe 6. The first pipe 51 connects the first outer tank outlet 11 of the outer tank 1 and the inlet P1 of the water distribution structure 3. One end of the second pipe 52 is connected to the rinsing outlet P3 of the water distribution structure 3, and the other end is connected to the separation outlet 45 of the centrifugal separation section 4 via the second connection port 75 of the connecting structure 7. One end of the third pipe 53 is connected to the separation outlet 45 of the centrifugal separation section 4 via the first connection port 74 of the connecting structure 7, and the other end extends into the interior of the outer tank 1 from the upper side. One end of the fourth pipe 54 is connected to the drain outlet P5 of the water distribution structure 3, and the other end extends to the outside of the garment processing device. The fifth pipe 6 connects the circulation outlet P2 of the water distribution structure 3 and the separation inlet 44 of the centrifugal separation section 4.

[0114] Therefore, the garment handling device includes a circulating water path L1, a rinsing water path L2, and a drain water path L3.

[0115] In the circulating water circuit L1, the washing water in the outer tank 1 flows from the first outer tank outlet 11 through the first pipe 51 from the inlet P1 into the third chamber C3 of the water distribution structure 3. After being filtered by the circulating filter F1, it enters the second chamber C2. Then, the washing water flows from the circulating outlet P2 through the fifth pipe 6 from the separation section inlet 44 into the centrifugal separation section 4. In the centrifugal separation section 4, foreign matter contained in the washing water is centrifuged and separated. Then, the washing water flows from the separation section outlet 45 through the space in the base 71, the first connection port 74, and the third pipe 53 back into the outer tank 1.

[0116] In the rinsing water path L2, the washing water in the outer tank 1 flows from the first outer tank outlet 11 through the first pipe 51 from the inlet P1 into the third chamber C3 of the water distribution structure 3. After being filtered by the drain filter F2, it enters the fourth chamber C4, and after being filtered by the outlet filter F3, it flows from the rinsing outlet P3 through the second pipe 52, the second connection port 75, and the space within the base 71 into the centrifugal separation section 4 via the separation section outlet 45 to rinse the centrifugal separation section 4. After rinsing the centrifugal separation section 4, the washing water after rinsing the centrifugal separation section 4 flows from the separation section inlet 44 through the fifth pipe 6 from the circulation outlet P2 into the second chamber C2 of the water distribution structure 3. This washing water then flows from the second chamber C2 through the circulation filter F1 into the third chamber C3.

[0117] In the drainage water path L3, the washing water in the outer tank 1 flows from the first outer tank outlet 11 through the first pipe 51 from the inlet P1 into the third chamber C3 of the water distribution structure 3. After being filtered by the drainage filter F2, it enters the fourth chamber C4 and is discharged from the drain outlet P5 through the fourth pipe 54 to the outside of the garment processing device. Furthermore, the washing water in the rinsing water path L2, after rinsing the centrifugal separation section 4 and flowing into the third chamber C3, also enters the fourth chamber C4 after being filtered by the drainage filter F2 and is discharged from the drain outlet P5 through the fourth pipe 54 to the outside of the garment processing device.

[0118] In the second embodiment, the pipe support 72 supports the fourth pipe 54 (that is, at least a portion of the drainage water passage L3) and positions the fourth pipe 54 above the centrifugal separation section 4. However, the pipe support 72 may also support at least a portion of the circulating water passage L1 or at least a portion of the flushing water passage L2.

[0119] The operation of the garment handling device configured as described above will be explained below.

[0120] When washing clothes, the garment handling unit first performs a washing process. Next, a rinsing process is performed, which may include, for example, a first intermediate spin-drying process, a first rinsing process, a second intermediate spin-drying process, and a second rinsing process. Finally, a spin-drying process is performed.

[0121] In addition, the garment handling device is capable of performing circulation, rinsing, and draining operations. Specifically, the garment handling device also has a control unit (not shown) that controls the garment handling device to perform at least one of the circulation, rinsing, and draining operations, so that the washing water in the outer tank 1 flows through the corresponding water passages in the circulation water passage L1, rinsing water passage L2, and draining water passage L3, respectively.

[0122] In at least one of the washing, first rinsing, and second rinsing processes (e.g., in the washing process), the garment handling device performs a cyclic operation. During this cyclic operation, the washing water in the outer tank 1 is circulated through the circulation water path L1 by the driving force of the drive device 43, and foreign matter contained in the washing water is centrifuged and separated as it flows through the centrifugal separator 4. At this time, the rotating drum 42 rotates in any direction under the drive of the drive device 43, thereby providing power to the washing water and causing it to circulate through the circulation water path L1. Furthermore, the pump 32 does not operate during the cyclic operation of the garment handling device.

[0123] During the first intermediate dehydration step, the second intermediate dehydration step, and the dehydration step, the garment handling device performs rinsing and draining actions. Pump 32 operates when the garment handling device performs at least one of the rinsing and draining actions.

[0124] In one configuration, the garment handling device simultaneously performs rinsing and draining actions by activating pump 32. During rinsing, the driving force of pump 32 causes the washing water in the outer tank 1 to rinse the centrifugal separator 4 via rinsing water passage L2 and return to the water distribution structure 3. At this time, driven by drive device 43, the rotating drum 42 rotates intermittently in the forward direction, intermittently in the reverse direction, or alternately in both directions. During draining, the driving force of pump 32 causes the washing water in the outer tank 1 to be discharged to the outside of the garment handling device via drain water passage L3. At this time, the washing water in rinsing water passage L2, which has rinsed the centrifugal separator 4 and returned to the water distribution structure 3 via circulation outlet P2, is also discharged to the outside of the garment handling device via drain water passage L3.

[0125] In another configuration, the rinsing action can begin earlier than the draining action. In this configuration, a drain valve (not shown) can be provided in the fourth pipe 54. When the rinsing action begins, the drain valve remains closed, allowing the pump 32 to operate. The pump 32's driving force causes the washing water in the outer tank 1 to rinse the centrifugal separator 4 via the rinsing water path L2 and return to the water distribution structure 3. After a predetermined time, the drain valve is opened, and the draining action begins. At this time, the pump 32's driving force causes the washing water in the outer tank 1 to be discharged to the outside of the garment processing device via the drain water path L3. Simultaneously, the washing water in the rinsing water path L2, which has rinsed the centrifugal separator 4 and returned to the water distribution structure 3 via the circulation outlet P2, is also discharged to the outside of the garment processing device via the drain water path L3.

[0126] The specific structure of the garment processing device of the second embodiment has been described above, but the second embodiment is not limited thereto.

[0127] For example, in the second embodiment, the garment processing device is described as having both a water-dispersing structure 3 and a centrifugal separation section 4. However, as a first variation of the second embodiment, the garment processing device may also be configured to have only a water-dispersing structure 3.

[0128] In this first variation, compared to the second embodiment, the water separation structure 3 omits the circulating outlet P2 and the circulating filter F1, and instead includes an inlet P1, a first outlet (rinsing outlet) P3, a second outlet (drainage outlet) P5, a drainage filter F2, and an outlet filter F3. Furthermore, the first outlet P3 is connected to the separation section inlet 44 of the centrifugal separation section 4 via a second pipe 52. In this case, the first outlet P3 functions as a circulating outlet, not a rinsing outlet.

[0129] The garment processing device includes a circulating water path L1 and a drain water path L3. In the circulating water path L1, the washing water in the outer tank 1 flows from the first outer tank outlet 11 through the first pipe 51 from the inlet P1 into the inlet chamber (third chamber) C3 of the water distribution structure 3. After being filtered by the drain filter F2, it enters the drain chamber (fourth chamber) C4, and after being filtered by the outlet filter F3, it flows from the first outlet P3 through the second pipe 52 from the separation section inlet 44 into the centrifugal separation section 4. In the centrifugal separation section 4, foreign matter contained in the washing water is centrifuged and separated. Afterward, the washing water returns to the outer tank 1 from the separation section outlet 45 through the third pipe 53. In the drain water path L3, the washing water in the outer tank 1 flows from the inlet P1 into the water distribution structure 3 and is discharged from the second outlet P5 to the outside of the garment processing device.

[0130] Furthermore, based on the first modification described above, a second modification can be constructed by further omitting the centrifugal separation unit 4. In this second modification, the first outlet P3 is connected to the outer tank 1 via the second pipe 52. The garment processing device includes a circulating water path L1 and a drain water path L3. In the circulating water path L1, the washing water in the outer tank 1 flows from the first outer tank outlet 11 through the first pipe 51 from the inlet P1 into the inlet chamber (third chamber) C3 of the water distribution structure 3, is filtered by the drain filter F2, enters the drain chamber (fourth chamber) C4, and is then filtered by the outlet filter F3 before returning to the outer tank 1 from the first outlet P3 via the second pipe 52. In the drain water path L3, the washing water in the outer tank 1 flows from the inlet P1 into the water distribution structure 3 and is discharged from the second outlet P5 to the outside of the garment processing device.

[0131] In addition, the second embodiment and its first and second modifications all include a drainage filter section F2, but it is not limited to this and the drainage filter section F2 may be omitted.

[0132] Furthermore, some specific structures in the second embodiment can also be appropriately applied to the first embodiment and its various modifications. For example, the specific structures of the circulating filter section F1 and the drain filter section F2 in the second embodiment can also be appropriately applied to the first embodiment and its various modifications. In addition, the connecting structure 7 in the second embodiment can also be appropriately applied to the first embodiment and its various modifications, and is particularly preferred to be applied to the second and third modifications of the first embodiment.

[0133] 3. Third Implementation Method

[0134] The main difference between the garment handling device of the third embodiment and the second embodiment is that, in addition to the water inlet P1, the circulating water outlet P2, the rinsing water outlet P3, and the drain outlet P5, the water distribution structure 3 also includes a rinsing return outlet P4. Hereinafter, refer to... Figures 17 to 20 The garment processing apparatus of the third embodiment will be described, and repeated descriptions of parts common to the second embodiment will be omitted as appropriate.

[0135] The garment processing device of the third embodiment includes an outer tank 1, a washing tank 2, a water separation structure 3, and a centrifugal separation unit 4.

[0136] The outer tub 1 and the washing tub 2 are, for example, formed into a bottomed cylindrical shape. The outer tub 1 is disposed inside the outer casing (not shown) of the garment handling device, and the washing tub 2 is rotatably disposed inside the outer tub 1.

[0137] The water distribution structure 3 includes a generally cylindrical shell 31. The shell 31 has an inner cavity C and is provided with an inlet P1, a circulation outlet P2, a flushing outlet (first outlet) P3, a flushing return outlet P4, and a drain outlet (second outlet) P5, which are respectively connected to the inner cavity C.

[0138] The inlet P1 and the flushing return outlet P4 are located near the center of the housing 31 along its axial direction, while the circulation outlet P2 is located near one end of the housing 31 along its axial direction. The flushing outlet P3 and the drain outlet P5 are located near the other end of the housing 31 along its axial direction, and are arranged close together. The circulation outlet P2 and the flushing return outlet P4 are located on the side opposite to the side where the inlet P1 is located relative to the central axis of the housing 31, and extend in a direction opposite to the extending direction of the inlet P1. Furthermore, the circulation outlet P2 and the flushing return outlet P4 are located on a straight line parallel to the axial direction of the housing 31.

[0139] In addition, a housing cover 33 is provided at one end of the housing 31 in the axial direction, and a pump 32 is provided at the other end of the housing 31 in the axial direction. The housing cover 33 blocks one end opening of the housing 31, and the pump 32 blocks the other end opening of the housing 31.

[0140] Furthermore, the flushing outlet P3 and drain outlet P5 are closer to the pump 32 than the inlet P1, the circulation outlet P2, and the flushing return outlet P4. Specifically, the flushing outlet P3 and drain outlet P5 are located on the peripheral wall of the housing 31, forming the pump chamber of the pump 32. In addition, the flushing outlet P3 and drain outlet P5 are arranged circumferentially on the housing 31.

[0141] In addition, the water distribution structure 3 also includes a circulating filter section F1 and a drainage filter section F2.

[0142] The circulating filter section F1 is a generally circular plate-shaped filter plate, connected to the housing cover 33 via a first connecting part 331. By installing the housing cover 33 onto the housing 31, the circulating filter section F1 is assembled into the inner cavity C. At this time, the outer peripheral surface of the circulating filter section F1 abuts against the inner peripheral surface of the housing 31, or against a step or similar portion provided on the inner peripheral surface of the housing 31. Axially, the circulating filter section F1 is located between the inlet P1 and the circulating outlet P2 of the housing 31. Thus, the circulating filter section F1 divides the inner cavity C into a first chamber C1 and a second chamber C2 along the axial direction of the housing 31. The first chamber C1 and the second chamber C2 are arranged along the axial direction of the housing 31. The inlet P1, the flushing outlet P3, the flushing return outlet P4, and the drain outlet P5 are connected to the first chamber C1, and the circulating outlet P2 is connected to the second chamber C2. Here, "the inlet P1, the flushing outlet P3, the flushing return outlet P4, and the drain outlet P5 are respectively connected to the first chamber C1, and the circulation outlet P2 is connected to the second chamber C2" means that the inlet P1, the flushing outlet P3, the flushing return outlet P4, and the drain outlet P5 are respectively located on the peripheral wall of the housing 31 forming the first chamber C1, and the circulation outlet P2 is located on the peripheral wall of the housing 31 forming the second chamber C2.

[0143] In addition, a partition 314 is provided inside the housing 31, which divides the first chamber C1 axially into a third chamber (water inlet chamber) C3 and a fourth chamber (drainage chamber) C4. A connecting port 315 is provided on the partition 314, through which the third chamber C3 and the fourth chamber C4 are connected. Furthermore, the water inlet P1 and the flushing return port P4 are respectively connected to the third chamber C3, and the flushing outlet P3 and the drain port P5 are respectively connected to the fourth chamber C4. Here, "the water inlet P1 and the flushing return port P4 are respectively connected to the third chamber C3, and the flushing outlet P3 and the drain port P5 are respectively connected to the fourth chamber C4" means that the water inlet P1 and the flushing return port P4 are respectively located on the peripheral wall of the housing 31 forming the third chamber C3, and the flushing outlet P3 and the drain port P5 are respectively located on the peripheral wall of the housing 31 forming the fourth chamber C4.

[0144] The drain filter section F2 is generally conical in shape, with a tapered guide surface that gradually widens as it approaches the connecting port 315. This drain filter section F2 is connected to the circulation filter section F1 via a second connecting part 332. The drain filter section F2 is assembled into the first chamber C1 by installing the housing cover 33 onto the housing 31. At this time, a predetermined radial filtration gap exists between the tapered guide surface of the circulation filter section F1 and the inner circumferential surface of the housing 31. Additionally, an axial filtration gap is provided between the drain filter section F2 and the partition plate 314. This prevents larger foreign objects such as buttons and coins from moving from the third chamber C3 to the fourth chamber C4 with the flow of washing water. The washing water in the third chamber C3 flows into the fourth chamber C4 through the connecting port 315 after being filtered by the drain filter section F2.

[0145] Furthermore, although not illustrated, in the third embodiment, the water distribution structure 3 may also include an outlet filter section F3, similar to the second embodiment. The outlet filter section F3 is located in the fourth chamber C4 and is installed on the inner circumferential surface of the peripheral wall of the housing 31 on the radially outer side of the impeller 321 at a location corresponding to the flushing outlet P3. The washing water in the water distribution structure 3 flows out of the housing 31 from the flushing outlet P3 after being filtered by the outlet filter section F3.

[0146] Furthermore, in the third embodiment, the centrifugal separation unit 4 adopts the same structure as in the second embodiment, that is, as... Figure 14As shown, the centrifugal separator 4 is used to separate foreign matter contained in the washing water in the outer tank 1. Specifically, the centrifugal separator 4 includes: an outer cylinder 41, which forms the outer outline of the centrifugal separator 4; a base 47 on which the outer cylinder 41 is mounted; a rotating cylinder 42, which is a hollow cylinder and is rotatably disposed inside the outer cylinder 41; and a drive device 43 for driving the rotating cylinder 42 to rotate. In addition, the outer cylinder 41 is composed of an upper part 411 and a lower part 412. The centrifugal separator 4 includes a separation inlet 44 and a separation outlet 45, with the separation inlet 44 located in the lower part 412 and the separation outlet 45 located in the upper part 411.

[0147] Furthermore, in the third embodiment, the garment handling device includes the same connection structure 7 as in the second embodiment. A detailed description of the connection structure 7 is omitted here.

[0148] In addition, the garment handling device also includes a first conduit 51, a second conduit 52, a third conduit 53, a fourth conduit 54, and a connecting conduit 61 serving as a fifth conduit. The fourth conduit 54 of the third embodiment and the fourth conduit 54 of the second embodiment (see...) Figures 6 to 8 (Similar to the previous one, illustration omitted here.)

[0149] One end of the first pipe 51 is connected to the lower part of the outer tank 1 (e.g., the outlet of the first outer tank), and the other end is connected to the inlet P1 of the water distribution structure 3. One end of the second pipe 52 is connected to the rinsing outlet P3 of the water distribution structure 3, and the other end is connected to the separation outlet 45 of the centrifugal separation section 4 via the connecting structure 7. One end of the third pipe 53 is connected to the separation outlet 45 of the centrifugal separation section 4 via the connecting structure 7, and the other end extends into the interior of the outer tank 1 from the upper side. One end of the fourth pipe 54 is connected to the drain outlet P5 of the water distribution structure 3, and the other end extends to the outside of the clothing treatment device. The connecting pipe 61 connects the circulation outlet P2 of the water distribution structure 3 and the separation inlet 44 of the centrifugal separation section 4, and also connects the rinsing return outlet P4 of the water distribution structure 3 and the separation inlet 44 of the centrifugal separation section 4.

[0150] The connecting pipe 61, serving as the fifth pipeline, is F-shaped and includes a main pipe 611, a first branch pipe 612, and a second branch pipe 613. One end of the main pipe 611 is connected to one end of the first branch pipe 612 and the second branch pipe 613. The other end of the main pipe 611 is connected to the separation inlet 44 of the centrifugal separation section 4. The other end of the first branch pipe 612 is connected to the flushing return port P4, and the other end of the second branch pipe 613 is connected to the circulating water outlet P2. The first branch pipe 612 branches out along a direction intersecting the extension direction of the main pipe 611, and is approximately straight. The second branch pipe 613 extends further along the extension direction of the main pipe 611, and is approximately L-shaped.

[0151] Additionally, a first check valve 614 is provided inside the first branch pipe section 612, or inside the flushing return port P4, or at the connection point between the first branch pipe section 612 and the flushing return port P4. Here, the first check valve 614 is provided at the connection point between the first branch pipe section 612 and the flushing return port P4. The first check valve 614 only allows washing water to flow from the first branch pipe section 612 into the inner cavity C.

[0152] A second check valve 615 is provided inside the second branch pipe section 613, inside the circulation outlet P2, or at the connection point between the second branch pipe section 613 and the circulation outlet P2. Specifically, the second check valve 615 is located at the connection point between the second branch pipe section 613 and the circulation outlet P2. The second check valve 615 only allows washing water to flow from the inner cavity C to the second branch pipe section 613.

[0153] Therefore, the garment handling device includes a circulating water path L1, a rinsing water path L2, and a drain water path L3.

[0154] In the circulating water circuit L1, the washing water in the outer tank 1 flows from the inlet P1 through the first pipe 51 into the third chamber C3 of the water distribution structure 3. After being filtered by the circulating filter F1, it enters the second chamber C2. Then, the washing water flows from the circulating outlet P2 through the second one-way valve 615, the second branch pipe 613 of the connecting pipe 61, and the main pipe 611 from the separation section inlet 44 into the centrifugal separation section 4. In the centrifugal separation section 4, foreign matter contained in the washing water is centrifuged and separated. Then, the washing water returns to the outer tank 1 from the separation section outlet 45 through the third pipe 53.

[0155] In the rinsing water path L2, the washing water in the outer tank 1 flows from the inlet P1 through the first pipe 51 into the third chamber C3 of the water distribution structure 3. After being filtered by the drain filter F2, it enters the fourth chamber C4, and after being filtered by the outlet filter F3, it flows from the rinsing outlet P3 through the second pipe 52 from the separation outlet 45 into the centrifugal separation section 4 to rinse the centrifugal separation section 4. The washing water after rinsing the centrifugal separation section 4 flows from the separation inlet 44 through the main pipe 611 and the first branch pipe 612 of the connecting pipe 61, and the first one-way valve 614 from the rinsing return port P4 into the third chamber C3 of the water distribution structure 3.

[0156] In the drainage water path L3, similar to the second embodiment, the washing water in the outer tank 1 flows from the inlet P1 through the first pipe 51 into the third chamber C3 of the water distribution structure 3, is filtered by the drainage filter F2, enters the fourth chamber C4, and is discharged from the drain outlet P5 to the outside of the garment processing device. Furthermore, the washing water in the rinsing water path L2, after rinsing the centrifugal separation section 4 and flowing into the third chamber C3, also enters the fourth chamber C4 after being filtered by the drainage filter F2, and is discharged from the drain outlet P5 to the outside of the garment processing device.

[0157] The operation of the garment handling device configured as described above will be explained below.

[0158] When washing clothes, the garment handling unit first performs a washing process. Next, a rinsing process is performed, which may include, for example, a first intermediate spin-drying process, a first rinsing process, a second intermediate spin-drying process, and a second rinsing process. Finally, a spin-drying process is performed.

[0159] Furthermore, the garment handling device is capable of performing circulation, rinsing, and draining operations. In other words, the washing water treatment method performed by the garment handling device includes circulation, rinsing, and draining operations. Specifically, the garment handling device also has a control unit (not shown) that controls the garment handling device to perform at least one of the circulation, rinsing, and draining operations, so that the washing water in the outer tank 1 flows through the corresponding water passages in the circulation water passage L1, rinsing water passage L2, and draining water passage L3, respectively.

[0160] In at least one of the washing, first rinsing, and second rinsing processes (e.g., in the washing process), the garment handling device performs a cyclic operation. During this cyclic operation, the washing water in the outer tank 1 is circulated through the circulation water path L1 by the driving force of the drive device 43, and foreign matter contained in the washing water is centrifuged and separated as it flows through the centrifugal separator 4. At this time, the rotating drum 42 rotates in any direction under the drive of the drive device 43, thereby providing power to the washing water and causing it to circulate through the circulation water path L1. Furthermore, the pump 32 does not operate during the cyclic operation of the garment handling device.

[0161] During the first intermediate dehydration step, the second intermediate dehydration step, and the dehydration step, the garment handling device performs rinsing and draining actions. Pump 32 operates when the garment handling device performs at least one of the rinsing and draining actions.

[0162] In one configuration, the garment handling device simultaneously performs rinsing and draining actions by activating pump 32. During rinsing, the driving force of pump 32 causes the washing water in the outer tank 1 to rinse the centrifugal separator 4 via rinsing water passage L2, and then returns to the water distribution structure 3 via rinsing return port P4. At this time, driven by drive device 43, the rotating drum 42 rotates intermittently in the forward direction, intermittently in the reverse direction, or alternately in both directions. During draining, the driving force of pump 32 causes the washing water in the outer tank 1 to be discharged to the outside of the garment handling device via drain water passage L3. At this time, the washing water in rinsing water passage L2 that has rinsed the centrifugal separator 4 and returned to the water distribution structure 3 via rinsing return port P4 is also discharged to the outside of the garment handling device via drain water passage L3.

[0163] In another configuration, the rinsing action can begin earlier than the draining action. In this configuration, a drain valve (not shown) can be installed in the fourth pipe. When the rinsing action begins, the drain valve remains closed, allowing the pump 32 to operate. The pump 32 drives the washing water in the outer tank 1 to rinse the centrifugal separator 4 via the rinsing water path L2 and return it to the water distribution structure 3. After a predetermined time, the drain valve is opened, and the draining action begins. At this time, the pump 32 drives the washing water in the outer tank 1 to be discharged to the outside of the garment processing device via the drain water path L3. Simultaneously, the washing water in the rinsing water path L2, which has rinsed the centrifugal separator 4 and returned to the water distribution structure 3 via the circulation outlet P2, is also discharged to the outside of the garment processing device via the drain water path L3.

[0164] In the third embodiment described above, detailed descriptions of the water outlet filter F3, the connecting structure 7, the fourth pipe 54, and the drainage water passage L3 are omitted. However, the water outlet filter F3, the connecting structure 7, the fourth pipe 54, and the drainage water passage L3 in the third embodiment can adopt the same structure as in the second embodiment.

[0165] The above describes the specific structure of the garment processing device according to the third embodiment, but the third embodiment is not limited thereto.

[0166] For example, in the third embodiment, the connecting pipe 61, which serves as the fifth conduit, is described as having an F-shaped structure. However, as a first variation of the third embodiment, the shape of the connecting pipe, which serves as the fifth conduit, can also be changed.

[0167] like Figure 21 , 22As shown, in this first modification, the garment processing device includes a connecting pipe 62 as a fifth conduit. The connecting pipe 62 includes a main pipe 621, a first branch pipe 622, and a second branch pipe 623. One end of the main pipe 621 is connected to one end of the first branch pipe 622 and one end of the second branch pipe 623, the other end of the main pipe 621 is connected to the separation inlet 44 of the centrifugal separation section 4, the other end of the first branch pipe 622 is connected to the rinsing return port P4, and the other end of the second branch pipe 623 is connected to the circulating water outlet P2.

[0168] More specifically, the main pipe section 621 has a first main pipe section 6211 and a second main pipe section 6212 that bends relative to the first main pipe section 6211. The second main pipe section 6212 branches at the bend between the first main pipe section 6211 and the second main pipe section 6212 to form a first branch pipe section 622 and a second branch pipe section 623. Here, "the bend between the first main pipe section 6211 and the second main pipe section 6212" refers to the portion of the pipe wall of the main pipe section 621 located between the first main pipe section 6211 and the second main pipe section 6212 that extends along a curve.

[0169] The first branch pipe portion 622 extends further along the extension direction of the second main pipe portion 6212, and the second branch pipe portion 623 branches along a direction intersecting the extension direction of the second main pipe portion 6212. The second branch pipe portion 623 has: a first portion 6231 that branches from the second main pipe portion 6212 and extends along a direction intersecting the extension direction of the second main pipe portion 6212; and a second portion 6232 that bends relative to the first portion 6231. The second main pipe portion 6212 bends at a 90° angle relative to the first main pipe portion 6211, and the second portion 6232 bends at a 90° angle relative to the first portion 6231.

[0170] Additionally, a one-way valve 624 is provided inside the first branch pipe section 622, inside the flushing return port P4, or at the connection point between the first branch pipe section 622 and the flushing return port P4. Here, the one-way valve 624 is provided at the connection point between the first branch pipe section 622 and the flushing return port P4. The one-way valve 624 only allows washing water to flow from the first branch pipe section 622 into the inner cavity C.

[0171] In the circulating water circuit L1, the washing water flowing into the water distribution structure 3 from the inlet P1 is filtered by the circulating filter section F1 and then flows into the centrifugal separation section 4 from the circulating outlet P2 via the second branch pipe section 623 and the main pipe section 621. At this time, since a one-way valve 624 is provided at the connection between the first branch pipe section 622 and the flushing return port P4, the washing water will not flow from the flushing return port P4 into the first branch pipe section 622. That is to say, when the washing water flows from the first branch pipe section 622 and the second branch pipe section 623 to the main pipe section 621, the flow rate of the washing water flowing through the second branch pipe section 623 is greater than the flow rate of the washing water flowing through the first branch pipe section 622.

[0172] In the rinsing water path L2, a portion of the washing water after rinsing the centrifugal separator returns from the first branch pipe 622 to the first chamber C1 via the rinsing return port P4, while another portion of the washing water flows from the second branch pipe 623 into the second chamber C2 via the circulation outlet P2 and returns to the first chamber C1 via the circulation filter F1. Since the first branch pipe 622 extends further along the extension direction of the second main pipe 6212, and the second branch pipe 623 branches along a direction intersecting the extension direction of the second main pipe 6212, when the washing water flows from the main pipe 621 side to the first branch pipe 622 and the second branch pipe 623 side, the washing water flows more readily towards the first branch pipe 622 side, and the flow rate of the washing water flowing through the first branch pipe 622 is greater than the flow rate of the washing water flowing through the second branch pipe 623.

[0173] Using this structure, in the rinsing water path L2, as a portion of the washing water flows from the second branch pipe 623 through the circulation outlet P2 into the second chamber C2 and returns to the first chamber C1 through the circulation filter F1, the flow of the washing water can be used to reverse clean the circulation filter F1, removing foreign matter adhering to the circulation filter F1 when the washing water flows through the circulation water path L1.

[0174] Furthermore, the third embodiment describes a structure in which the circulating filter unit F1 divides the inner cavity C into a first chamber C1 and a second chamber C2 in the axial direction of the housing 31. However, as a second variation of the third embodiment, the arrangement of the circulating filter unit F1 can also be changed.

[0175] like Figure 23 As shown, in this second variation, the circulating filter section F1 is a long strip extending along the axial direction of the housing 31, dividing the inner cavity C into a first chamber C1 and a second chamber C2 in a direction intersecting the axial direction of the housing 31. The circulating water outlet P2 is located on the side opposite to the side where the water inlet P1 and the flushing return port P4 are located relative to the central axis of the housing 31.

[0176] The garment processing device includes a connecting pipe 63 as a fifth conduit. The connecting pipe 63 includes a main pipe 631, a first branch pipe 632, and a second branch pipe 633. One end of the main pipe 631 is connected to one end of the first branch pipe 632 and one end of the second branch pipe 633, and the other end of the main pipe 631 is connected to the separation inlet 44 of the centrifugal separation unit 4. The other end of the first branch pipe 632 is connected to the rinsing return port P4, and the other end of the second branch pipe 633 is connected to the circulating water outlet P2.

[0177] The first branch pipe 632 extends further along the extension direction of the main pipe 631, and the second branch pipe 633 branches along a direction intersecting the extension direction of the main pipe 631. The first branch pipe 632 is approximately L-shaped, and the second branch pipe 633 is approximately J-shaped.

[0178] Additionally, a one-way valve 634 is provided inside the first branch pipe section 632, inside the flushing return port P4, or at the connection point between the first branch pipe section 632 and the flushing return port P4. Here, the one-way valve 634 is provided at the connection point between the first branch pipe section 632 and the flushing return port P4. The one-way valve 634 only allows washing water to flow from the first branch pipe section 632 into the inner cavity C.

[0179] In the circulating water circuit L1, the washing water flowing into the water distribution structure 3 from the inlet P1 is filtered by the circulating filter section F1 and then flows into the centrifugal separation section 4 from the circulating outlet P2 via the second branch pipe section 633 and the main pipe section 631. At this time, because a one-way valve 624 is provided at the connection between the first branch pipe section 632 and the flushing return port P4, the washing water will not flow from the flushing return port P4 into the first branch pipe section 632. That is to say, when the washing water flows from the first branch pipe section 632 and the second branch pipe section 633 to the main pipe section 631, the flow rate of the washing water flowing through the second branch pipe section 633 is greater than the flow rate of the washing water flowing through the first branch pipe section 632.

[0180] In the rinsing water path L2, a portion of the washing water after rinsing the centrifugal separator returns from the first branch pipe 632 to the first chamber C1 via the rinsing return port P4, while another portion of the washing water flows from the second branch pipe 633 into the second chamber C2 via the circulation outlet P2 and returns to the first chamber C1 via the circulation filter F1. Since the first branch pipe 632 extends further along the extension direction of the main pipe 631, and the second branch pipe 633 branches along a direction intersecting the extension direction of the main pipe 631, when the washing water flows from the main pipe 631 side to the first branch pipe 632 and the second branch pipe 633 side, the washing water flows more readily towards the first branch pipe 632 side, and the flow rate of the washing water flowing through the first branch pipe 632 is greater than the flow rate of the washing water flowing through the second branch pipe 633.

[0181] Using this structure, in the rinsing water path L2, as a portion of the washing water flows from the second branch pipe 633 through the circulation outlet P2 into the second chamber C2 and returns to the first chamber C1 through the circulation filter F1, the flow of the washing water can be used to reverse clean the circulation filter F1, removing foreign matter adhering to the circulation filter F1 when the washing water flows through the circulation water path L1.

[0182] Furthermore, in the second variation of the third embodiment, a structure is described in which the circulating filter unit F1 divides the inner cavity C into a first chamber C1 and a second chamber C2 in a direction intersecting the axial direction of the housing 31. This structure can also be applied to the first embodiment, the second embodiment, and their various variations.

[0183] The present disclosure has been described above through embodiments. However, the present disclosure is not limited to the described embodiments and variations. For example, other embodiments implemented by arbitrarily combining the constituent elements described in this specification, or by excluding certain constituent elements, may also be used as embodiments of the present disclosure. In addition, variations of the embodiments that can be conceived by those skilled in the art without departing from the spirit of the present disclosure, that is, the meaning expressed by the statements in the claims, are also included in the present disclosure.
