Description

  The present invention relates to a yarn waste collecting device for collecting yarn waste in a washing tub of a washing machine and a washing machine provided with the yarn waste collecting device.

  In the washing machine disclosed in Patent Document 1 below, a pulsator is disposed at the center bottom of the dehydration tank, and a reflux water passage is attached to the inner side surface of the dehydration tank. The lower end of the return channel is connected to the side of the pulsator. A filter unit provided with a filter member is attached to the upper part of the reflux channel. When the pulsator rotates, the wash water on the lower surface of the pulsator is pushed out and reaches the reflux channel, and ascends the reflux channel. The washing water having risen in the reflux water channel enters the inside of the filter unit, passes through the filter member, and is discharged into the dewatering tank. As a result, lint such as lint contained in the washing water is collected inside the filter unit.

  In the washing machine disclosed in Patent Document 2 below, the pulsator is disposed inside the washing and dewatering tank so as to be able to horizontally rotate. The inner wall side surface of the washing and dewatering tank rotatably supports the filter frame having the opening of the bag-like filter in a horizontal direction. When the pulsator rotates to generate a water flow in the washing and dewatering tank, the water flow enters the filter through the opening of the filter. Thus, yarn waste and the like in the wash water are captured.

  In the washing machine of Patent Document 1, even if lint is present near the filter unit in the dewatering tank, the lint flows along a long path of rising once in the reflux water channel after having descended to the bottom of the dewatering tank. If not, it will not be collected by the filter unit. This makes it difficult to collect thread waste efficiently.

  In the washing machine of Patent Document 2, since the opening of the filter is exposed to the inside of the washing and dewatering tank, the filter can directly collect the lint located near the opening in the washing and dewatering tank. Therefore, lint can be collected efficiently. However, since the laundry tends to be entangled in the bag-like filter that has run out into the washing and dewatering tank, the filter is likely to be damaged. Also, if the force of the water flow in the washing and dewatering tank weakens, the lint collected in the filter will not be pressed into the filter by the force of the water flow, so it will flow out from the opening of the filter into the washing and dewatering tank There is a risk of

  The present invention has been made under such background, and aims to improve the collection efficiency of yarn waste while preventing the outflow and breakage of collected yarn waste, and the yarn waste collection device It aims at providing a washing machine provided with a collection device.

  Furthermore, the present invention is characterized in that the structure is a baffle for stirring the laundry in the washing tub.

  Further, in the present invention, the intake port includes a first intake port and a second intake port arranged side by side so as to sandwich the outflow preventing member in the circumferential direction of the washing tub, and the open position is A first open position in which the outflow prevention member connects between the accommodation chamber and the first intake port and blocks the space between the accommodation chamber and the second intake port; And a second open position for blocking the space between the storage chamber and the first inlet while communicating the chamber with the second inlet, and the outflow prevention member is configured to receive the second inlet from the second inlet. Also, the force of water flowing into the first intake port is increased to move to the first open position, and the force of water flowing into the second intake port is stronger than the first intake port to increase the number 2) It is characterized by moving to the open position.

  Further, in the present invention, the closed position is between the first open position and the second open position, and the outflow preventing member flows into each of the first inlet and the second inlet. When the force of water weakens, it moves to the closed position by its own weight, and in the closed position, collectively blocking between the first intake port and the second intake port and the storage chamber It features.

  Further, the present invention is a washing machine comprising a cylindrical washing tub having a central axis extending in the vertical direction or in the direction of inclination with respect to the vertical direction, and the above-described waste thread collecting device.

According to the present invention, the waste thread collecting device is used in a washing machine provided with a cylindrical washing tub having a central axis extending in the vertical direction or in the direction of inclination with respect to the vertical direction.
Since the waste thread collecting device is removably embedded in the surface portion of the structure in the washing tub, it is disposed in the washing tub so as not to protrude from the surface portion. Therefore, the laundry in the washing tank hardly collides with or is entangled in the yarn waste collecting device, so that breakage of the yarn waste collecting device can be prevented.
In the waste thread collecting device, an inlet for taking in waste thread is provided on the surface of the main body so as to be exposed in the washing tub. Thus, the lint collecting device can collect the lint present near the intake in the washing tub directly and promptly. Therefore, the collection efficiency of the yarn waste in the yarn waste collecting device can be improved.
The outflow prevention member movably provided in the waste thread collecting device moves to the open position by increasing the force of the water flowing into the intake port, and the storage chamber inside the main body portion communicates with the intake port. Let Thus, the yarn waste collection device can efficiently collect yarn waste contained in the water by utilizing the momentum of the water flowing into the inlet. The collected lint is stored in the storage chamber. In a state where the force of the water flowing into the intake port is strengthened, the lint contained in the storage chamber is pushed into the storage chamber by the force of the water flowing into the intake port, so the collected lint can be taken into the intake port. Can be prevented from flowing out of the storage room via
On the other hand, the outflow prevention member moves to the closed position and shuts off the space between the storage chamber and the intake port by weakening the force of the water flowing into the intake port. Thereby, even if the force of the water flowing into the intake port is weakened, it is possible to prevent the collected thread waste from flowing out of the storage chamber via the intake port.

  Further, according to the present invention, the structure on which the waste thread collecting device is mounted in the washing tub is a baffle for stirring the laundry in the washing tub. The waste thread collecting device is disposed in the washing tub so as not to protrude from the surface of the baffle. Therefore, when the baffle agitates the laundry in the washing tank, the laundry does not easily collide with or be entangled in the yarn waste collecting device, so that the yarn waste collecting device can be prevented from being damaged.

Further, according to the present invention, the intake for taking in yarn waste includes a first intake and a second intake arranged side by side so as to sandwich the outflow prevention member in the circumferential direction of the washing tub. . And the open position mentioned above contains the 1st open position and the 2nd open position.
The outflow prevention member moves to the first open position by increasing the force of water flowing into the first intake port more than the second intake port, and communicates with the storage chamber and the first intake port with the storage chamber Block between the second intake port. At this time, the lint collecting device is included in the water flowing into the first inlet while preventing the collected lint from flowing out of the storage chamber via the second inlet. It can collect thread waste.
On the other hand, when the flow of water in the washing tank is reversed, the momentum of the water flowing into the second inlet may be stronger than the first inlet. In that case, the outflow prevention member moves to the second open position, and blocks the space between the storage chamber and the first inlet while communicating the storage chamber with the second inlet. At this time, the lint collecting device is included in the water flowing into the second inlet while preventing the collected lint from flowing out of the storage chamber via the first inlet. It can collect thread waste.
As described above, even when the flow of water in the washing tank is reversed, the waste thread collecting device causes the collected waste thread to flow out of the storage chamber through the intake port. While being prevented, it is possible to collect thread waste contained in water flowing into the intake port.

  Further, according to the present invention, the outflow prevention member is between the first open position and the second open position by its own weight when the force of water flowing into each of the first inlet and the second inlet is weakened. To the closed position, and in the closed position, blocks between the first and second inlets and the storage chamber collectively. This can prevent the collected yarn waste from flowing out of the storage chamber via either the first inlet or the second inlet.

  Further, according to the present invention, in the washing machine provided with the above-described waste thread collecting device, in the waste thread collecting device, the collection efficiency of the waste thread is improved while the outflow of collected waste thread and It is possible to prevent damage to the waste thread collecting device.

  The water tank 3 is made of, for example, a resin, and is formed in a bottomed cylindrical shape. The water tank 3 integrally has a substantially cylindrical circumferential wall 3B having an opening 3A at the upper end, and a disk-shaped bottom wall 3C that blocks the hollow portion of the circumferential wall 3B from the lower side X2. The opening 3A is opened and closed by a cover 9 connected to the circumferential wall 3B. In the water tank 3, water such as tap water, bath water and liquid in which detergent is dissolved is accumulated.

  The washing tub 4 is made of metal, for example, and formed in a bottomed cylindrical shape which is slightly smaller than the water tub 3. The washing tub 4 integrally has a substantially cylindrical circumferential wall 4B having an inlet / outlet 4A at the upper end, and a disk-shaped bottom wall 4C that blocks the hollow portion of the circumferential wall 4B from the lower side X2. The central axis 10 passing through the circular center of the washing tub 4 extends vertically along the vertical direction X in this embodiment. Therefore, the washing machine 1 is a vertical washing machine in which the washing tub 4 is vertically disposed. The washing tub 4 may be disposed obliquely by the central axis 10 extending in the inclination direction with respect to each of the vertical direction X and the horizontal direction H.

  The washing tub 4 of this embodiment is housed in the water tub 3 and is rotatable around a central axis 10. The rotational direction of the washing tub 4 coincides with the circumferential direction Y of the water tub 3 and the washing tub 4. In the following, the radial direction based on the central axis 10 is referred to as the radial direction Z, and in the radial direction Z, the side facing the central axis 10 is referred to as the radially inner side Z1, and the side away from the central axis 10 is the radially outer side Z2. It is called. The circumferential direction Y and the radial direction Z in this embodiment are both directions along the horizontal direction H.

The user of the washing machine 1 can put the laundry S into and out of the washing tub 4 through the opened entrance 4A. A through hole (not shown) is formed in the bottom wall 4C, and the water in the water tank 3 can move between the water tank 3 and the washing tank 4 through the through hole. Therefore, the water level of the water tank 3 and the water level of the washing tank 4 almost coincide with each other.

  The motor 5 is disposed below the bottom wall 3C of the water tank 3 at X2. The output shaft of the motor 5 is branched into a tubular first output shaft 5A extending upward along the central axis 10 and a second output shaft 5B inserted with play relative to the first output shaft 5A. . The motor 5 can output the driving force from one or both of the first output shaft 5A and the second output shaft 5B.

  The first output shaft 5A extends upward X1 and penetrates the circular center of the bottom wall 3C. The first output shaft 5A has a flange portion 5C that protrudes like a hook between the bottom wall 3C and the bottom wall 4C, and is connected to the washing tub 4 by the flange portion 5C being fixed to the bottom wall 4C.

When the motor 5 is driven to transmit the driving force to the second output shaft 5B, the pulsator 6 rotates around the central axis 10. At this time, the rotation of the washing tub 4 is in a stopped state. During the washing operation and the rinsing operation, the laundry S in the washing tank 4 is stirred by the convex portion 6A of the pulsator 6 rotating in the circumferential direction Y. Thereby, a water flow mainly along the circumferential direction Y is generated in the washing tub 4. By rotating the washing tub 4 together with the pulsator 6, it is possible to generate a water flow that flows more vigorously in the circumferential direction Y.

However, two members sandwiching the middle plate 53 in the storage chamber 60 The regions are in communication with one another via the gap 54 described above.

  When the waste thread collection device 8 is changed from the maintenance state shown in FIG. 4 to the use state shown in FIG. 3 with the outflow prevention member 21 in the closed position, the storage chamber 60 is formed with the recess 34 (FIG. In the state of being accommodated in the reference), the discharge port 28 of the main wall 24 of the cover portion 22 is opposed from the radially outer side Z2 and is covered from the radially inner side Z1 by the filter member 29 of the main wall 24. The storage chamber 60 at this time exists inside the main body portion 20 of the outflow prevention member 21 and is in communication with the outside of the main body portion 20 only via the mesh of the filter member 29.

  When the waste thread collecting device 8 in use is fitted into the recess 7D of the structure 7 described above, the upper and lower engaging portions 31 and 32 of the main body portion 20 engage with the structure 7, as shown in FIG. As shown, a lint collecting device 8 is attached to the structure 7. The waste thread collecting device 8 in this state is embedded in the surface portion 7C of the structure 7, and the surface portion 20A of the main body portion 20 is exposed in the washing tub 4, and the surface portion 7C of the structure 7 is And is almost coplanar. In the surface portion 20A, each of the first intake port 30A and the second intake port 30B is exposed to the inside of the washing tub 4 in a state of facing both sides in the circumferential direction Y.

  Thus, the lint collection device 8 is disposed in the washing tub 4 so as not to protrude from the surface portion 7C of the structure 7 which is a baffle. Therefore, when the structure 7 stirs the laundry S in the washing tank 4, the laundry S in the washing tank 4 is less likely to collide with or be entangled with the yarn waste collecting device 8, so the yarn waste collecting device 8 Can prevent the damage.

  For example, when the engagement between each of the engaging portions 31 and 32 and the structure 7 is released by operating the engaging portion 31, the waste thread collecting device 8 is disengaged from the recess 7D of the structure 7 and the structure It can be separated from seven. Thereafter, the separated waste thread collecting device 8 is put in the maintenance state of FIG. 4 so that the waste thread stored in the storage chamber 60 can be taken out and discarded.

  Next, the operation of the waste thread collecting device 8 in the use state mounted on the structure 7 will be described with reference to FIGS. 5 to 7. 5 to 7 show a state in which the internal space of the main body portion 20 of the waste thread collecting device 8 is viewed from the radially inner side Z1.

  In FIG. 5, the state in which the outflow prevention member 21 is in the closed position is illustrated. At this time, the first intake port 30A and the second intake port 30B described above are arranged side by side so as to sandwich the outflow prevention member 21 in the circumferential direction Y. The outflow prevention member 21 in the closed position has the first intake port 30A and the second intake port 30B by the first plate 51 closing the first communication port 48 and the second plate 52 closing the second communication port 49. Between the storage room 60 and the storage room 60 are collectively blocked.

  Of the circumferential direction Y, the direction from the first inlet 30A to the second inlet 30B is referred to as a first direction Y1, and the direction from the second inlet 30B to the first inlet 30A is It is called 2 directions Y2. When the flow of water in the first direction Y1 or the second direction Y2 occurs in the washing tub 4, the outflow prevention member 21 pivots from the closed position to the open position. The open position includes a first open position and a second open position on both sides of the closed position in the rotational direction of the outflow prevention member 21. That is, the closed position is between the first open position and the second open position.

  The outflow preventing member 21 is always urged toward the closed position by its own weight, particularly by the own weight of the intermediate plate 53. It is necessary to make the intermediate plate 53 heavier than at least the first plate 51 and the second plate 52 in order to generate a biasing force for moving the outflow prevention member 21 to the closed position. As described above, with the configuration in which the self-weight of the outflow prevention member 21 is used, the number of parts can be reduced as compared with the configuration in which the outflow prevention member 21 is biased to the closed position by separately providing an energizing member such as a spring.

  When a flow of water in the first direction Y1 occurs in the washing tub 4, the water flows from the first inlet 30A into the inside of the main body 20 as shown by the white arrow, and 1 plate 51 is pushed in the first direction Y1. At this time, since the force of water flowing into the first inlet 30A is stronger than that of the second inlet 30B, the outflow prevention member 21 pivots from the closed position to the first open position shown in FIG.

  The outflow prevention member 21 in the first open position is configured such that the first plate 51 is dismounted from the first communication port 48 downward X 2, enters the storage chamber 60 and extends in the up-down direction X, thereby the storage chamber 60 and the first It communicates with the inlet 30A. Therefore, yarn waste K contained in the water flowing into the first intake port 30A among the water accumulated in the washing tub 4 is taken in by the first intake port 30A and accommodated in the accommodation chamber 60. In this case, since the tip 51A of the first plate 51 at this time is separated from the lower wall 42 of the base portion 23 with the gap 55, thread waste K passes through the gap 55 in the storage chamber 60. Not only in the front side region on the side of the first communication port 48 but also in the back side region on the side of the second communication port 49.

  As described above, the first intake port 30A is provided in the surface portion 7C of the main body portion 20 so as to be exposed in the washing tub 4 (see FIG. 2). As a result, the lint collecting device 8 can collect the lint K present near the first inlet 30A in the laundry tub 4 directly and promptly. Further, the yarn waste collecting device 8 can efficiently collect the yarn waste K contained in the water by utilizing the momentum of the water flowing into the first inlet 30A. Therefore, the collection efficiency of the yarn waste K in the yarn waste collecting device 8 can be improved. Then, in a state where the force of the water flowing into the first intake port 30A is intensified, the lint K stored in the storage chamber 60 is the first communication port 48 from the first intake port 30A as indicated by the white arrow. Since it is pressed into the storage chamber 60 by the force of the water flowing into the storage space, it is possible to prevent the collected lint K from flowing out of the storage chamber 60 via the first inlet 30A.

  The water flowing into the first intake port 30A passes through the storage chamber 60 and is returned from the discharge port 28 into the washing tub 4 as indicated by the thick broken arrow in FIG. When the water passes through the discharge port 28, the lint K contained in the water is captured by the filter member 29 provided in the discharge port 28 and is retained in the storage chamber 60.

  Returning to FIG. 6, in the outflow prevention member 21 in the first open position, the second plate 52 is dislocated from the second communication port 49 upward X 1 and along the second inclined surface 45 B of the projection 43 from downward X 2 is there. On the other hand, the outflow prevention member 21 in the first open position is accommodated in the storage chamber 60 by the intermediate plate 53 coming into contact with the upper end portion 47C of the second partition wall 47B from the lower X2 and closing the second communication port 49 from the lower X2. And the second inlet 30B. Therefore, in the state where the outflow prevention member 21 is in the first open position, the lint collection device 8 prevents the lint K from flowing out of the storage chamber 60 via the second inlet 30B. At the same time, thread waste K contained in the water flowing into the first inlet 30A can be collected.

  When the force of water flowing into the first inlet 30A weakens with the outflow prevention member 21 in the first open position, the outflow prevention member 21 moves to the closed position by its own weight, as shown in FIG. In the closed position, the space between the first inlet 30A and the second inlet 30B and the storage chamber 60 are collectively blocked. As a result, even if the force of water flowing into the first inlet 30A is weakened, the first waste inlet 30A and the second inlet are taken up by the thread scrap K in the collected storage chamber 60 being floated by buoyancy. It can be leaked out of the storage room 60 via any of the mouth 30B, and the inside of the washing tub 4 can be prevented from being contaminated with the lint K.

  On the other hand, when the flow of water in the washing tank 4 reverses, and the flow of water in the washing tank 4 in the second direction Y2 opposite to the first direction Y1 occurs, the water is indicated by the black arrow. As shown, it flows into the inside of the main body 20 from the second inlet 30B and pushes the second plate 52 of the outflow prevention member 21 in the second direction Y2. At this time, since the force of water flowing into the second inlet 30B is stronger than that of the first inlet 30A, the outflow prevention member 21 pivots from the closed position to the second open position shown in FIG.

  The outflow preventing member 21 in the second open position is configured such that the second plate 52 is dismounted from the second communication port 49 downward X 2, enters the accommodation chamber 60 and extends in the up-down direction X, thereby the accommodation chamber 60 and the second It communicates with the inlet 30B. Therefore, yarn waste K contained in the water flowing into the second intake port 30 </ b> B among the water accumulated in the washing tub 4 is taken in by the second intake port 30 </ b> B and stored in the storage chamber 60. Since the tip 52A of the second plate 52 at this time is in a state of being separated from the lower wall 42 of the base portion 23 with the gap 56, thread waste K passes through the gap 56 in the storage chamber 60. Not only in the front side region on the side of the second communication port 49 but also in the back side region on the side of the first communication port 48.

  As described above, the second intake port 30B is provided on the surface portion 7C of the main body portion 20 so as to be exposed in the washing tub 4 (see FIG. 2). Thereby, the lint collecting device 8 can collect the lint K present near the second inlet 30B in the washing tub 4 directly and promptly. Moreover, the lint collecting device 8 can collect lint K contained in the water efficiently by using the momentum of the water flowing into the second inlet 30B. Therefore, the collection efficiency of the yarn waste K in the yarn waste collecting device 8 can be improved. Then, in a state where the force of the water flowing into the second intake port 30B is intensified, the lint K accommodated in the accommodation chamber 60 is from the second intake port 30B to the second communication port 49 as shown by the black arrow. Since it is pressed into the storage chamber 60 by the force of the water flowing into the storage space, it is possible to prevent the collected waste thread K from flowing out of the storage chamber 60 via the second inlet 30B.

  As described above, the water flowing into the second intake port 30B passes through the storage chamber 60 and is returned from the discharge port 28 to the inside of the washing tank 4. At that time, thread waste K contained in the water passing through the discharge port 28 Is captured by the filter member 29 provided at the discharge port 28 and retained in the storage chamber 60 (see FIG. 1).

  Further, in the outflow prevention member 21 in the second open position, the first plate 51 is dislocated from the first communication port 48 upward X1 and along the first inclined surface 45A of the projecting portion 43 from below X2. On the other hand, the outflow prevention member 21 in the second open position is accommodated in the storage chamber 60 by the intermediate plate 53 coming into contact with the upper end portion 47C of the first partition wall 47A from the lower side X2 and closing the first communication port 48 from the lower side X2. And the first inlet 30A. Therefore, in the state where the outflow prevention member 21 is in the second open position, the lint collection device 8 prevents the lint K from flowing out of the storage chamber 60 via the first inlet 30A. At the same time, thread waste K contained in the water flowing into the second inlet 30B can be collected.

  When the force of the water flowing into the second inlet 30B weakens with the outflow prevention member 21 in the second open position, the outflow prevention member 21 moves to the closed position by its own weight, as shown in FIG. In the closed position, the space between the first inlet 30A and the second inlet 30B and the storage chamber 60 are collectively blocked. As a result, even if the force of the water flowing into the second inlet 30B is weakened, the first waste inlet 30A and the second inlet are taken up by the thread scrap K in the collected storage chamber 60 being lifted by buoyancy. It can be leaked out of the storage room 60 via any of the mouth 30B, and the inside of the washing tub 4 can be prevented from being contaminated with the lint K.

  As described above, even in the case where the flow of water in the washing tub 4 is reversed, the yarn waste collection device 8 stores the collected yarn waste K via any of the intake ports 30. The thread waste K contained in the water flowing into the inlet 30 can be collected while preventing the flow out of the chamber 60.

  The present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the claims.

  For example, in the embodiment described above, the outflow preventing member 21 is moved from the closed position to the first open position and the second open position on the assumption that water flows reversely in two directions of the first direction Y1 and the second direction Y2. It can move to two open positions: position. When the water flows only in one of the first direction Y1 and the second direction Y2, the outflow prevention member 21 moves from the closed position to only one open position. Specifically, as in the modification shown in FIG. 8, when water flows only in the first direction Y1, the main body portion 20 omits the second intake port 30B and the second communication port 49. It is a structure and the outflow prevention member 21 which exists in a closed position in FIG. 8 is the structure from which the 2nd board 52 was abbreviate | omitted.

  When the flow of water in the first direction Y1 occurs in the washing tub 4, a portion of the water flows from the first inlet 30A into the main body 20 and flows out, as shown by the outlined arrows in FIG. The first plate 51 of the preventing member 21 is pushed in the first direction Y1. At this time, since the force of water flowing into the first intake port 30A is strengthened, the outflow prevention member 21 is pivoted from the closed position to the open position shown in FIG. 9, and in the open position, the accommodation chamber 60 and the first intake It communicates with the port 30A. On the other hand, when the force of water flowing into the first inlet 30A weakens with the outflow prevention member 21 in the open position, the outflow prevention member 21 is pivoted to the closed position by its own weight, as shown in FIG. In the closed position, the space between the storage chamber 60 and the first inlet 30A is shut off.

  In this modification, in order to make the dead weight of the intermediate plate 53 work effectively to move the outflow prevention member 21 smoothly to the closed position, the intermediate plate 53 when the outflow prevention member 21 is in the closed position is the first It is preferable to extend obliquely with respect to the vertical direction X so as to be away from the plate 51. Further, in the case where the flow of water only in the second direction Y2 occurs in the washing tub 4, the configuration of the lint collection device 8 is a configuration in which FIGS. 8 and 9 are reversed in the circumferential direction Y. .

  In addition, in the radial direction Z, a slight gap 61 as shown in FIG. 1 is provided between the outflow preventing member 21 and each of the filter member 29 and the vertical wall 40 so that the outflow preventing member 21 can rotate smoothly. It is preferred to be secured. Of course, if smooth rotation of the outflow prevention member 21 can be ensured, a seal member (not shown) for closing the gap 61 is used as the outflow prevention member 21 in order to prevent the leakage of thread waste K from the storage chamber 60. It may be provided in

  Moreover, although the structure 7 mentioned above was a baffle, it may be a flow path (not shown) for pumping up the water in the washing tub 4 instead. In this case, a plurality of vanes (not shown) radially extending from the central axis 10 are formed on the lower surface of the pulsator 6, and the vanes push water into the inlet of the lower end of the flow path by the rotation of the pulsator 6. Thus, the water ascends in the flow path and is discharged from the outlet at the upper end of the flow path and returned into the washing tub 4. Since this is repeatedly used for washing by circulating the water in the washing tub 4, washing with less water becomes possible. For example, the waste thread collecting device 8 is attached to this flow path so that the water flowing in the flow path is discharged from the discharge port 28 from the intake port 30 via the storage chamber 60 and returns to the inside of the washing tub 4 If it does, thread waste K contained in water which flows through a channel can be collected.

  In the embodiment described above, one thread waste collecting device 8 is attached to one structure 7, but a plurality of thread waste collecting devices 8 are attached to one structure 7. It is also good. Moreover, when the washing machine 1 is provided with a plurality of structures 7, the yarn waste collecting device 8 may be attached to all the structures 7, or there is a structure 7 to which the yarn waste collecting device 8 is not attached.
