Description

Technical Field

[0001] The present invention relates to a garment processing apparatus having a detachable filter device, and a filter device detachably installed in the garment processing apparatus. Background Technology

[0002] Typically, a washing machine, as an example of a garment handling device, has a detachable filter that captures foreign objects such as lint or hair contained in the wash water or rinse water. The filter is installed either in a drain line for discharging wash water, such as from the tub, to the outside of the washing machine, or in a circulation line for circulating the wash water inside and outside the tub.

[0003] As is well known, such filtration devices, for example, include a filter body with a grid-like structure having multiple water passages. According to this filtration device, washing water or the like flows from the inside to the outside of the filter body through the multiple water passages, thereby capturing foreign matter such as fibers contained in the washing water or the like from the inside of the filter body. However, in this type of filtration device, foreign matter easily becomes entangled in the grid-like mesh of the filter body. Therefore, it becomes difficult to remove foreign matter from the filter body, resulting in poor cleanability.

[0004] On the other hand, as disclosed in Patent Document 1, a filter body is provided with multiple protrusions. According to this type of filter device, foreign objects such as fibers contained in washing water can be hooked onto the multiple protrusions of the filter body and thus captured.

[0007] Patent Document 1: Japanese Patent No. 6626772 Summary of the Invention

[0008] According to the filter device disclosed in Patent Document 1, the captured foreign objects are relatively easy to remove because they are only hooked onto multiple protrusions on the filter body, thereby improving cleanliness. However, in this type of filter device, compared to a filter device with a grid-like mesh on the filter body, the foreign object capture performance decreases.

[0009] Therefore, the configuration provided by the present invention relates to a filter device that can be detachably installed in a garment processing device, which can improve cleaning performance and improve the collection performance of foreign objects even when the filter body is provided with multiple protrusions.

[0010] The garment processing device involved in this invention is a garment processing device equipped with a detachable filter device for capturing foreign objects in water. The filter device includes: a filter main body for capturing foreign objects, an outer side including the edge of the filter main body, and an inner side provided on the inner side of the outer side. The height of the upper ends of a plurality of inner protrusions provided on the inner side is greater than or equal to the height of the upper ends of a plurality of outer protrusions provided on the outer side.

[0011] Furthermore, the filtration device involved in this invention is a detachable filtration device that can be installed in a garment processing device and captures foreign objects in water. The filtration device includes: a filter main body for capturing foreign objects, an outer side including the edge of the filter main body, and an inner side provided on the inner side of the outer side. The height of the upper ends of a plurality of inner protrusions provided on the inner side is greater than or equal to the height of the upper ends of a plurality of outer protrusions provided on the outer side.

[0012] Based on the above configuration, foreign objects can be efficiently captured by the relatively long inner protrusion. Furthermore, even if a foreign object cannot be captured by the inner protrusion, it can be captured by the outer protrusion at a position further outward than the inner protrusion, thereby improving the foreign object capture performance.

Detailed Implementation

[0026] Hereinafter, with reference to the accompanying drawings, one embodiment of the garment handling apparatus will be described. Figure 1 as well as Figure 2 The illustrated washing machine 10 is an example of a clothing processing device that performs washing, rinsing, and spin-drying processes on clothes. It includes an outer casing 11, a door 12, a water tank 13, and a rotating drum 14. In this embodiment, the door 12 side is considered the front side of the washing machine 10 relative to the outer casing 11. The horizontal direction, perpendicular to the front-back direction, is considered the left-right direction. The direction orthogonal to both the front-back and left-right directions is considered the up-down direction. The washing machine 10 is, for example, a front-loading washing machine, and the central axis of the water tank 13 and the rotation central axis of the rotating drum 14 are inclined relative to the horizontal or the ground. Furthermore, the washing machine 10 may or may not have a drying function, such as a heat pump or heater type.

[0027] The outer casing 11 is formed into a generally rectangular box shape using materials such as steel plates. The water tank 13 is housed inside the outer casing 11 and is elastically supported by shock absorbers 15. The rotating trough 14 is rotatably housed inside the water tank 13. Both the water tank 13 and the rotating trough 14 are formed as bottomed cylinders, with one axial side open and the other side closed.

[0028] For example Figure 3As illustrated, the washing machine 10 includes a water supply device 16, a drain valve 17, a circulation pump 18, and a filter unit 30. The water supply device 16 is located inside the outer casing 11, at the upper part of one side of the sink 13. The water supply device 16 includes a water supply valve 161 and a water inlet box 162. The water supply valve 161 is connected to an external water source, such as a tap water pipe (not shown), and is opened and closed by a control device (not shown) that controls all operations of the washing machine 10. When the water supply valve 161 is opened, water supplied from the external water source is supplied to the sink 13 through the water supply valve 161 and the water inlet box 162.

[0029] A drain valve 17 and a circulation pump 18 are located below the water tank 13. The drain valve 17 is, for example, a solenoid valve, and is controlled to open and close by a control device (not shown). The inflow side of the drain valve 17 is connected to a drain outlet 131 located near the bottom of the water tank 13 via connecting pipes 191 and 192. The discharge side of the drain valve 17 is connected to the outside of the washing machine via a drain pipe 20. In this configuration, the path from the drain outlet 131 of the water tank 13 through the drain valve 17 and then through the drain pipe 20 to the outside of the washing machine is called drain path A. This drain path A is an example of the water path provided by the washing machine 10. When the circulation pump 18 is stopped and the drain valve 17 is opened, the washing water or rinsing water remaining in the water tank 13 is discharged to the outside of the washing machine through drain path A.

[0030] The circulation pump 18 is configured to be controlled by a control device (not shown) to adjust the water discharge rate. The inflow side of the circulation pump 18 is connected to the drain outlet 131 located near the bottom of the water tank 13 via connecting pipes 191 and 193. The discharge side of the circulation pump 18 is connected to the discharge section 132 located in the water tank 13 via a circulation hose 21. In this configuration, the path from the drain outlet 131 of the water tank 13, through the circulation pump 18, and then from the discharge section 132 back to the water tank 13 is called the circulation water path B. This circulation water path B is an example of the water path provided by the washing machine 10. When the circulation pump 18 is activated with the drain valve 17 closed, the washing water or rinsing water remaining in the water tank 13 will pass through the circulation water path B and return to the water tank 13 and the rotating tank 14 from the discharge section 132. However, the circulation water path B is not mandatory.

[0031] like Figure 3As shown, the filter unit 30 is installed in at least one of the waterways, either the drain path A or the circulating water path B. In this embodiment, the filter unit 30 is installed in both the drain path A and the circulating water path B. That is, the filter unit 30 is installed in a common waterway that runs between the drain outlet 131 and the drain valve 17, and between the drain outlet 131 and the circulating pump 18. The filter unit 30 is capable of capturing foreign matter such as fibers or hair contained in the water flowing in both the drain path A and the circulating water path B.

[0032] Additionally, the filter unit 30 includes a filter housing 40 and a filter device 50. The filter housing 40 is constructed of a rigid material, such as a synthetic resin material. The filter housing 40 is disposed on the drain passage A and on the circulating water passage B, forming part of both the drain passage A and the circulating water passage B.

[0033] like Figure 4 as well as Figure 5 As illustrated, the filter housing 40 is formed as a long cylindrical shape with an opening on the front side, extending in one direction from the opening. Specifically, it is a long cylindrical shape that slopes slightly downwards from the front to the rear of the washing machine 10. A connecting pipe 191 is connected to the inlet 41 of the filter housing 40. A connecting pipe 192 is connected to the outlet 42 of the filter housing 40. A connecting pipe 193 is connected to the circulation port 43 of the filter housing 40.

[0034] When the water in the tank 13 is drained to the outside of the washing machine, water flows into the filter housing 40 from the inlet 41, and the inflowing water is discharged from the outlet 42. Alternatively, when the water in the tank 13 is circulated, water flows into the filter housing 40 from the inlet 41, and the inflowing water is discharged from the circulation port 43.

[0035] The filter device 50 is configured to be detachable by inserting and removing it from the filter housing 40. In this case, the filter device 50 is installed inside the filter housing 40 by inserting it in, and can be removed from the filter housing 40 by pulling it out. Furthermore, the opening of the filter housing 40 is... Figure 1 The illustrated cover component 111 is opened and closed.

[0036] Next, a detailed description of the configuration example of the filter device 50 will be provided. For example... Figures 6 to 9 As illustrated, the filter device 50 includes an operation section 51 and a filter body section 52. The filter device 50 is configured by mounting the filter body section 52 onto the operation section 51. Both the filter body section 52 and the operation section 51 are made of a rigid material, such as a synthetic resin material.

[0037] The operating unit 51 is a component operated by the user when assembling or disassembling the filter device 50 relative to the filter housing 40. In this case, it integrally includes a cylindrical portion 55 and a knob portion 56. The cylindrical portion 55 is generally cylindrical in shape and has an engaging portion 55a on its outer surface. The engaging portion 55a is shaped to engage with an engaging portion (not shown) provided on the inner circumferential surface of the opening of the filter housing 40.

[0038] The knob portion 56 is formed as a plate with a predetermined thickness, protruding from the front side of the cylindrical portion 55 toward the side opposite to the filter body portion 52, i.e., the front side. The knob portion 56 is a component that is grasped by the user with their fingers when the filter device 50 is assembled or disassembled from the filter housing 40. By grasping the knob portion 56 with their fingers, the user can easily operate the operation portion 51, which is a rotation operation.

[0039] When the filter device 50 is installed inside the filter housing 40, the user first inserts the filter device 50 into the filter housing 40, and then grasps the knob 56 to rotate the entire operating unit 51 in the predetermined installation direction D1. Accordingly, the engaging part 55a on the filter device 50 side engages with the engaging part on the filter housing 40 side, and the filter device 50 is fixed in the state of being inserted into the filter housing 40. Therefore, the filter device 50 can be installed inside the filter housing 40.

[0040] On the other hand, when disassembling the filter device 50 from the filter housing 40, the user first grasps the knob 56 and rotates the entire operating unit 51 in the predetermined disassembly direction D2. This releases the engagement between the engaging part 55a on the filter device 50 side and the engaged part on the filter housing 40 side. The user then pulls the filter device 50 out of the filter housing 40. Thus, the filter device 50 can be disassembled from the filter housing 40.

[0041] The filter body 52 is the main part of the filter device 50 used to capture foreign objects, and it has a base 52a that forms its base. The base 52a of the filter body 52 is formed to be relatively long along one direction, which is the long side direction of the filter housing 40 in this case. In addition, as Figure 8 as well as Figure 9 As illustrated, the base 52a of the filter body 52 has a shape in which its bottom is lower than the two edges in the short side direction of the base 52a, that is, the so-called bottom shape.

[0042] Furthermore, the filter body 52 has a rear end face 52b at the rear end of the base 52a. The rear end face 52b has a shape in which its upper part follows the inner circumferential surface of the filter housing 40. However, the upper end of the rear end face 52b is not formed along the inner circumferential surface of the filter housing 40 but is formed as a flat surface. In addition, the rear end face 52b has a shape in which its lower part follows the shape of the so-called bottom of the base 52a.

[0043] In addition, such as Figure 7 As illustrated, the filter device 50 includes an outer portion 53 and an inner portion 54. The outer portion 53 is configured as part of the base 52a of the filter body portion 52, including the two edges in the short side direction of the base 52a and the rear edge of the base 52a. In addition, a part of the outer portion 53, which is the inner portion, reaches the bottom surface of the so-called bottom-shaped base 52a.

[0044] On the other hand, the inner portion 54 is provided inside the outer portion 53 as part of the base 52a of the filter body portion 52. In addition, the entire inner portion 54 is located on the bottom surface of the so-called bottom-shaped base 52a.

[0045] Furthermore, a plurality of outer protrusions 53a are provided on the outer side portion 53. In this case, the plurality of outer protrusions 53a are formed such that the upper end of the outermost outer protrusion 53a-OUT located in the short side direction of the base 52a is lower than the upper end of the outer protrusion 53a-IN located in the inner side position compared to the outer protrusion 53a-OUT.

[0046] In addition, a plurality of inner protrusions 54a are provided in the inner side portion 54. Moreover, the height of the upper end of the plurality of inner protrusions 54a provided in the inner side portion 54 is greater than or equal to the height of the upper end of the outer protrusion 53a-OUT located at the outermost position in the short side direction of the base portion 52a among the plurality of outer protrusions 53a provided in the outer side portion 53.

[0047] In addition, the height of the upper end of the plurality of inner protrusions 54a provided in the inner part 54 is approximately equal to or exactly equal to the height of the upper end of the outer protrusion 53a other than the outer protrusion 53a-OUT located in the short side direction of the base 52a among the plurality of outer protrusions 53a provided in the outer part 53, that is, the outer protrusion 53a-IN.

[0048] Furthermore, in the inner portion 54, a plurality of inner protrusions 54a are arranged in a straight line along the long side direction of the base 52a. Additionally, the plurality of inner protrusions 54a are arranged with equal intervals between them. In this case, the separation interval of the inner protrusions 54a is at least greater than the separation interval of the outer protrusions 53a.

[0049] Furthermore, the density of the plurality of inner protrusions 54a in the inner portion 54 is less than the density of the plurality of outer protrusions 53a in the outer portion 53. That is, the number of inner protrusions 54a per unit area is less than the number of outer protrusions 53a per unit area. Specifically, in this case, five inner protrusions 54a are provided in the inner portion 54. In contrast, at least five or more outer protrusions 53a are provided in the outer portion 53. That is, the outer portion 53 has a number of outer protrusions 53a that exceeds the number of inner protrusions 54a.

[0050] Furthermore, the inner portion 54 includes a plurality of unformed protrusion portions 54b, where no inner protrusion 54a is formed. The unformed protrusion portions 54b are disposed between the plurality of inner protrusions 54a provided in the inner portion 54. Additionally, each unformed protrusion portion 54b is sized such that at least one human finger can be inserted.

[0051] Furthermore, adjacent unformed protrusions 54b in the inner portion 54 are connected by a connecting space 54c. Accordingly, the plurality of inner protrusions 54a are each surrounded by a continuous space formed by the unformed protrusions 54b and the connecting space 54c. In the connecting space 54c, instead of inner protrusions 54a, a space is formed that allows, for example, a rod-shaped component thinner than a human finger to be inserted. Therefore, in the inner portion 54, for example, a rod-shaped component thinner than a human finger can be inserted into the unformed protrusion 54b or the connecting space 54c, and this component can be moved. Moreover, by moving the thin rod-shaped component in the unformed protrusion 54b or the connecting space 54c in this way, foreign objects trapped between the inner protrusions 54a and the innermost outer protrusion 53a can be removed.

[0052] Furthermore, the upper ends of both the outer protrusion 53a and the inner protrusion 54a are lower than the upper end of the rear end face 52b of the filter device 50. Therefore, as Figure 10 As illustrated, even if the user holds the operating part 51 of the filter device 50 and the rear end face 52b touches the ground D, the situation where the outer protrusion 53a or the inner protrusion 54a touches the ground D can be avoided.

[0053] Furthermore, the surfaces of the outer protrusion 53a and the inner protrusion 54a are formed to be rougher than the unformed portion 54b. That is, the outer protrusion 53a and the inner protrusion 54a are configured such that their surfaces have multiple fine uneven shapes. In addition, in the filter device 50, the surfaces of components that are different from the outer protrusion 53a and the inner protrusion 54a, such as the operating part 51, the base 52a, and the rear end face 52b, are formed to be smoother.

[0054] In addition, such as Figure 9As illustrated, the rear end face 52b of the filter device 50 has a plurality of drainage holes 52c, in this case five, located lower than the upper ends of the outer protrusion 53a and the inner protrusion 54a. In this case, the drainage holes 52c are rectangular holes that are longer in the vertical direction. Furthermore, among the drainage holes 52c, the drainage hole 52c at the center of the short side of the filter device 50 is the largest, and the drainage holes 52c become smaller towards the edges. However, the upper ends of the drainage holes 52c are all lower than the upper ends of the inner protrusion 54a and the outer protrusion 53a.

[0055] Furthermore, a drain hole 52d is also provided at the lowest part of the rear end face 52b of the filter device 50. In this case, the drain hole 52d is located below the largest central drain hole 52c among the plurality of drain holes 52c. In addition, the drain hole 52d communicates with the bottom of the base 52a of the filter body 52. ​​Accordingly, residual water retained at the bottom of the base 52a of the filter body 52 can also be discharged through the drain hole 52d.

[0056] According to the embodiment described above, the filter device 50, which is detachably installed in the water path of the washing machine 10, includes: a filter main body 52 that captures foreign objects, an outer side 53 including the edge of the filter main body 52, and an inner side 54 provided inside the outer side 53. The height of the upper ends of the plurality of inner protrusions 54a provided in the inner side 54 is greater than or equal to the height of the upper ends of the plurality of outer protrusions 53a provided in the outer side 53, which is the height of the upper ends of the outer protrusions 53a-OUT.

[0057] According to this configuration, since the filter device 50 is configured such that a plurality of protrusions 53a and 54a are provided in the filter body 52, which is the main body for capturing foreign objects, it is possible to easily remove foreign objects hooked by the protrusions 53a and 54a. Compared with conventional filter devices that are formed in a grid shape with a plurality of water passage holes, the cleanability can be improved.

[0058] Furthermore, according to the filter device 50, in the filter body 52, the height of the upper end of the inner protrusion 54a of the inner portion 54 is greater than or equal to the height of the upper end of the outer protrusion 53a of the outer portion 53, which is the upper end of the outer protrusion 53a-OUT. With this configuration, foreign objects can be efficiently captured by the relatively long inner protrusion 54a. Moreover, even if foreign objects cannot be captured by the inner protrusion 54a, they can be captured by the outer protrusion 53a-OUT at a position further outward than the inner protrusion 54a, thereby improving the foreign object capture performance.

[0059] Furthermore, according to the filter device 50, in the outer portion 53, the height of the upper end of the outer protrusion 53a-IN is greater than or equal to the height of the upper end of the outer protrusion 53a-OUT. With this configuration, foreign objects can be efficiently captured by the relatively long outer protrusion 53a-IN. Moreover, even if foreign objects cannot be captured by the outer protrusion 53a-IN, they can be captured by the outer protrusion 53a-OUT at a position further outward than the outer protrusion 53a-IN, thereby improving the foreign object capture performance.

[0060] As described above, according to this embodiment, the filter device 50, which can be detachably installed in the washing machine 10, adopts a form in which multiple protrusions 53a and 54a are provided in the filter body 52. ​​Even in this case, the cleaning performance can be improved, and the foreign matter capture performance can also be improved.

[0061] Furthermore, according to this embodiment, the density of the plurality of inner protrusions 54a in the inner portion 54 is lower than the density of the plurality of outer protrusions 53a in the outer portion 53. With this configuration, for example, a human finger or a thin rod-shaped component can easily be inserted between the plurality of inner protrusions 54a in the inner portion 54, thus making it easy to remove foreign objects captured by the filter body portion 52.

[0062] Furthermore, according to this embodiment, the filter device 50 has a shape in which the bottom of the filter body portion 52 is lower than the edge portion, and the inner side portion 54 is provided at the bottom of such a filter body portion 52. Figure 11 As illustrated, the water W flowing into the filter housing 40 from the inlet 41 first flows towards the bottom of the filter body 52, and then flows out in a manner that extends from the bottom of the filter body 52 towards the edge. Therefore, foreign matter contained in the water W flowing into the filter housing 40 is first captured by the plurality of inner protrusions 54a of the inner portion 54, and then, foreign matter contained in the water passing through the inner portion 54 can be captured by the outer protrusions 53a of the outer portion 53.

[0063] That is, according to the filter device 50, the inner protrusion 54a of the inner part 54 can function as a primary filter, and the outer protrusion 53a of the outer part 53 can function as a secondary filter. Through such a dual filtration structure, the foreign matter capture performance can be further improved.

[0064] Furthermore, according to this embodiment, the inner portion 54 includes a plurality of unformed protrusion portions 54b, in which the inner protrusion 54a is not formed. With this configuration, foreign objects entangled in the inner protrusion 54a can be easily removed by inserting, for example, a human finger or a thin rod-shaped component into the unformed protrusion portions 54b, thereby further improving cleanability.

[0065] Furthermore, according to this embodiment, the upper ends of the outer protrusion 53a and the inner protrusion 54a are lower than the upper end of the rear end face 52b of the filter device 50. According to this configuration, as... Figure 10 As illustrated by arrow H, by striking the ground D with the rear end face 52b, foreign objects wrapped around the outer protrusion 53a or the inner protrusion 54a can be removed by utilizing the impact or vibration generated during the striking. Accordingly, foreign objects can be removed even if the user does not directly touch the foreign objects wrapped around the outer protrusion 53a or the inner protrusion 54a.

[0066] Furthermore, according to the filter device 50, the upper end of the rear end face 52b is a flat surface. Therefore, the rear end face 52b can be easily struck against the ground D, thereby making it easier to remove foreign objects by striking.

[0067] Furthermore, according to this embodiment, the rear end face 52b of the filter device 50 has a drain hole 52c at a position lower than the upper end of the outer protrusion 53a and the upper end of the inner protrusion 54a. With this configuration, since drainage from the filter body 52 via the drain hole 52c occurs at a position lower than the upper end of the outer protrusion 53a or the upper end of the inner protrusion 54a, drainage can be reliably performed based on the outer portion 53 or the inner portion 54. Accordingly, the discharged water can reliably contact the outer protrusion 53a or the inner protrusion 54a, thereby further improving the foreign matter capture performance.

[0068] Furthermore, according to this embodiment, a drain hole 52d is provided at the lowest part of the rear end face 52b of the filter device 50. With this configuration, water retained at the bottom of the filter body 52 can be discharged from the drain hole 52d, thereby preventing water from remaining at the bottom of the filter body 52.

[0069] Furthermore, according to this embodiment, the surfaces of the outer protrusion 53a and the inner protrusion 54a are formed to be rougher than the unformed portion 54b. With this configuration, foreign objects can be more easily wrapped around the outer protrusion 53a or the inner protrusion 54a, thereby further improving the foreign object capture performance.

[0070] Furthermore, this embodiment is not limited to the one described above, and can be extended or modified as follows. For example, the number of inner protrusions 54a provided in the inner portion 54 is not limited to five, and can be appropriately varied up to a number less than that of the outer protrusions 53a. Additionally, the spacing between the plurality of inner protrusions 54a in the inner portion 54 can be different. Furthermore, the surfaces of the outer protrusions 53a and the inner protrusions 54a can be formed to be smooth. Furthermore, the arrangement positions of the plurality of outer protrusions 53a in the outer portion 53 and the plurality of inner protrusions 54a in the inner portion 54 can also be appropriately varied.
