Technical problem to be solved by the invention

However, in the above washing machine, since the washing water is pressurized into the water passage by the rotation of the agitating blade and is pumped into the lint filter from the bottom of the inner tank, the water passage cannot be enlarged and lint cannot be sufficiently captured.

Accordingly, an object of the present invention is to provide a washing machine having high trapping performance for lint contained in washing water.

Means for solving the problems

A washing machine according to one aspect of the present invention includes:

a bottomed cylindrical inner tank having a bottom and a peripheral portion and storing washing water;

a stirring blade rotatably provided at the bottom in forward and reverse directions, for stirring the washing water stored in the inner tub to generate forward and reverse water flows; and

a lint trap attached to an inner peripheral surface of the peripheral side portion,

the lint pickup device has:

a housing;

a catching chamber provided inside the housing, and capable of catching lint contained in the washing water;

a first side hole portion provided at one side in a circumferential direction of the inner groove of the housing and communicating an outside of the housing and the trap chamber;

a second side hole portion provided at the other side in the circumferential direction of the inner groove of the housing and communicating the outside of the housing and the trap chamber;

In addition, a washing machine according to an aspect of the present invention includes:

a bottomed cylindrical inner tank having a bottom and a peripheral portion and storing washing water;

a stirring blade rotatably provided at the bottom in forward and reverse directions, for stirring the washing water stored in the inner tub to generate forward and reverse water flows; and

a lint trap attached to an inner peripheral surface of the peripheral side portion,

the lint pickup device has:

a housing;

a catching chamber provided inside the housing, and capable of catching lint contained in the washing water;

a first side hole portion provided at one side in a circumferential direction of the inner groove of the housing and communicating an outside of the housing and the trap chamber;

a second side hole portion provided at the other side in the circumferential direction of the inner groove of the housing and communicating the outside of the housing and the trap chamber;

the second side hole portion is provided with a second through hole portion that penetrates the second opening/closing portion in the rotation direction of the second opening/closing portion.

Effects of the invention

According to the washing machine of the above aspect, the partition portion that partitions the first side hole portion and the second side hole portion is provided inside the capturing chamber of the lint capturing device, and the partition portion has the plurality of protruding portions that are provided with the gaps between adjacent ones. Thus, the washing water flowing into the trap chamber from the one side hole portion can be smoothly distributed over the entire trap chamber, and lint contained in the inflowing washing water can be reliably trapped, thereby realizing a washing machine having high trapping performance for lint contained in the washing water.

In addition, according to the washing machine of the above aspect, the first opening/closing portion of the casing is provided with the first through hole portion that penetrates the first opening/closing portion in the rotation direction of the first opening/closing portion at least in a portion that covers the first side hole portion, and the second opening/closing portion of the casing is provided with the second through hole portion that penetrates the second opening/closing portion in the rotation direction of the second opening/closing portion at least in a portion that covers the second side hole portion. Accordingly, compared with the washing machine provided with the lint trapping device without the first through hole and the second through hole in each of the first opening and closing part and the second opening and closing part, the amount of the washing water flowing into the trapping chamber can be increased, and thus the lint trapping performance of the lint contained in the washing water can be improved. As a result, a washing machine having high trapping performance for lint contained in the washing water can be realized.

The mounting groove portion 34 extends in the extending direction of the rotation axis of the inner groove 30 (i.e., the vertical direction in fig. 2), and is configured to be able to mount the lint trap 100.

Further, a recess 35 for facilitating handling of a mounting claw portion 113 of a lint trap 100, which will be described later, is provided on the upper side of the mounting groove portion 34 of the device mounting portion 33, and water flow forming groove portions 36 are provided on both sides of the mounting groove portion 34 in the circumferential direction. By the water flow forming groove portion 36, a strong water flow of the washing water is formed in the circumferential direction toward the lint trap 100.

Further, an annular balancer 32 for suppressing vibration when the inner tank 30 rotates at a high speed is provided at an upper end portion of the inner tank 30 so as to surround the upper opening 303.

The stirring blade 2 is rotated by the driving unit 40 in accordance with an operation program or the like instructed by a user via an operation panel. For example, in the case of performing a washing or rinsing operation, the agitating blade 2 is alternately and repeatedly rotated in the forward rotation direction and the reverse rotation direction at a rotation speed of 50 to 150 rpm. In addition, when the dehydration operation is performed, the stirring vanes 2 are rotated in the reverse rotation direction at a rotation speed of 0 to 1000rpm together with the inner tank 30.

The driving unit 40 includes: a motor 41, a belt mechanism 42 for transmitting the rotation output of the motor 41, a clutch/brake mechanism 43, a dewatering shaft 44 and an agitating blade shaft 45 coaxially disposed at the center of the clutch/brake mechanism 43. The dewatering shaft 44 and the stirring blade shaft 45 have a double-shaft structure, in which the dewatering shaft 44 is disposed on the outer side and the stirring blade shaft 45 is disposed on the inner side. The dewatering shaft penetrates the bottom surface of the outer tub 20 from below to above and supports the inner tub 30.

In the case of performing a washing or rinsing operation in the washing machine 1, the drain valve 58 is closed by the control device 70, and water is stored only in the inner tub 30. In addition, when the dehydration operation is performed, the control device 70 closes the drain valve 58 and the water in the inner tank 30 is discharged to the outside. In various operations, the dewatering shaft 44, the stirring blade shaft 45, and the inner tank 30 are rotated by the driving motor 41, but the inner tank 30 can continue to adopt a waterproof structure in a rotatable state with respect to the seal holder 54 by the oil seal pressed into the inside of the seal holder 54.

Next, the lint trap 100 will be described in detail with reference to fig. 2 to 10. In fig. 3, 9 and 10, only the cross section of the lint picker 100 is shaded.

As shown in fig. 2, the lint trap 100 is installed with the front surface facing the inside of the inner tank 30 and facing the radially inner side of the inner tank 30. As shown in fig. 4 and 5, this lint trap 100 includes a substantially rectangular box-shaped case 101 constituted by a device main body 110 and a cover 120. The inside of the housing 101 is provided with a trap chamber 102 (shown only in fig. 5) which can trap lint contained in the washing water. In fig. 4 and 5, the X direction corresponds to the circumferential direction of the inner groove 30, the Y direction corresponds to the radial direction of the inner groove 30, and the Z direction corresponds to the height direction of the inner groove 30.

As shown in fig. 4 and 5, the apparatus body 110 has a substantially rectangular hollow box shape. As shown in fig. 4, the upper end portion in the Z direction of the device main body 110 is provided with a mounting claw portion 113 for mounting the lint trap 100 to the device mounting portion 33 of the inner tank 30. In addition, a lower end portion in the Z direction of the apparatus main body 110 is provided with a cover support portion 112 that pivotably supports the cover 120.

As shown in fig. 3, the front surface of the device body 110 is provided with a curved surface 118 that curves along the peripheral side portion 302 of the inner groove 30 in the circumferential direction of the inner groove 30. In addition, as shown in fig. 4, a plurality of front hole portions 103 are provided on the front surface of the apparatus main body 110, penetrate the apparatus main body 110 in the Y direction, and communicate with the outside of the apparatus main body 110 and the trap chamber 102. Each front hole 103 is disposed along the longitudinal direction of the front surface of the apparatus main body 110, is covered with a metal or resin screen, and can remove foreign matter (lint) such as lint contained in the washing water when the washing water passes therethrough.

Further, a groove portion 116 is provided between the front hole portion 103 and the attachment claw portion 113 on the front surface of the apparatus main body 110, for allowing the user to easily attach and detach the lint trapping apparatus 100 to and from the apparatus attachment portion 33 by hooking a finger. As shown in fig. 5, a pair of recesses 117 for fixing the cover 120 to the apparatus main body 110 are provided on both sides of the groove portion 116 in the X direction. Each recess 117 is provided so as to open on the rear surface side of the apparatus main body 110.

As shown in fig. 5, the apparatus main body 110 is provided with a first side hole portion 114 and a second side hole portion 115 on both sides in the X direction, respectively. Each of the first side hole portion 114 and the second side hole portion 115 is provided in a part of an edge portion of the back face opening portion 111 side of the apparatus main body 110, and has a substantially rectangular cutout shape extending in the longitudinal direction of the apparatus main body 110. Further, in a plan view viewed in the Y direction, each of the first side hole portion 114 and the second side hole portion 115 is provided symmetrically with respect to a center line CL1 (shown in fig. 4) in the short side direction of the device body 110, and a center line CL3 in the longitudinal direction (only the center line of the first side hole portion 114 is shown in fig. 4) is arranged on the lower end portion side of the device body 110 with respect to a center line CL2 (shown in fig. 4) in the long side direction of the device body 110.

Further, as shown in fig. 5, each of the first and second side hole portions 114 and 115 is provided with a first shutter 130 and a second shutter 140, respectively, which are one example of a switching portion switching the first and second side hole portions 114 and 115. Each of the first and second baffles 130 and 140 is formed of: rectangular plate-shaped body portions 131 and 141; outflow prevention portions 132 and 142 provided at one end in the short-side direction of the inner side surfaces of the main bodies 131 and 141 (i.e., the end on the rear surface opening 111 side); and side wall portions 133 (only the first flap 130 is shown in fig. 5) provided at the longitudinal ends of the main bodies 131 and 141. In addition, each of the first baffle 130 and the second baffle 140 is arranged symmetrically with respect to a center line CL1 (shown in fig. 4) in the short side direction of the apparatus main body 110 in a plan view seen in the Y direction.

Each of the body portions 131, 141 is provided so as to cover substantially the entire inner side surface in the X direction of the apparatus body 110, and has a rotation shaft portion 135 (only one is shown in fig. 5) extending in the Z direction at the other end in the short side direction thereof (i.e., the end on the front side). The rotation shaft 135 is rotatably supported by a bearing 104 of the apparatus main body 110 described later.

Further, in the case where the first and second side hole portions 114 and 115 are closed, each of the first and second baffles 130 and 140 may be opposed to the first and second side hole portions 114 and 115 and the peripheral portions of the first and second side hole portions 114 and 115, and cover the peripheral portions of the first and second side hole portions 114 and 115 in addition to the first and second side hole portions 114 and 115.

That is, each of the first and second shutters 130 and 140 is rotatably supported by the apparatus body 110 of the casing 101 so that the first and second side holes 114 and 115 can be opened and closed. In the first embodiment, the first shutter 130 is configured to be rotatable by about 45 degrees with respect to the side surface on which the first side hole portion 114 of the apparatus main body 110 is provided, and the second shutter 140 is configured to be rotatable by about 45 degrees with respect to the side surface on which the second side hole portion 115 of the apparatus main body 110 is provided.

As shown in fig. 5, each outflow prevention part 132, 142 extends substantially perpendicularly from the corresponding body part 131, 141 toward the inside of the trap chamber 102. That is, each of the first damper 130 and the second damper 140 has a substantially L-shape in a cross-sectional view orthogonal to the rotation shaft 135 (i.e., Z direction).

In addition, as shown in fig. 5, the first shutter 130 is provided with a first through hole portion 134 penetrating the first shutter 130 in the rotational direction, and the second shutter 140 is provided with a second through hole portion 144 penetrating the second shutter 140 in the rotational direction. Each of the first and second through hole portions 134 and 144 has a slit shape extending on each main body portion 131 and 141 and each outflow prevention portion 132 and 142 along a direction (i.e., Y direction) intersecting with an extending direction of a rotation axis of each of the first and second shutters 130 and 140.

In detail, as shown in fig. 5, the first shutter 130 is provided with a plurality of first through hole parts 134. In the first embodiment, as shown in fig. 6, the first through-hole parts 134 are set such that the length W1 of the first through-hole part 134 in the extending direction of the rotation axis of the first flap 130 (i.e., the Z direction) is 2mm, and the linear distance W2 between adjacent first through-hole parts 134 is set to 6 mm. That is, the length W1 of the first through-hole 134 in the extending direction of the rotation axis of the first flap 130 is 1/3 of the linear distance W2 between the adjacent first through-hole 134. Further, the length H2 of the first through hole 134 in the Y direction is 2/3 of the length H1 of the main body 131 in the short side direction (i.e., the width of the main body 131).

In addition, as shown in fig. 7, an inclined surface 136 is provided at an end portion of the body portion 131 of the first through hole portion 134 in the short side direction (i.e., the Y direction). The inclined surface 136 is inclined so as to be away from the rotation shaft 135 as it approaches the outflow prevention portion 132 in the thickness direction (i.e., X direction) of the body 131. By providing the inclined surface 136 in this way, when the first shutter 130 is rotated and the first side hole portions 114 are opened, the opening area of the first through hole portions 134 in a cross-sectional view (i.e., a plan view seen in the X direction) of the housing 101 can be increased as compared to a state where the inclined surface 136 is not provided. Accordingly, since the inflow amount of the washing water flowing from the case 101 into the trap chamber 102 through the first side hole 114 can be increased without increasing the outflow amount of the washing water flowing out of the trap chamber 102 to the outside of the case 101 through the first side hole 114, the trapping performance of lint contained in the washing water can be improved.

Further, the length H2 of the first through-hole 134 in the Y direction is preferably set to 2/3 or less, which is the length H1 of the main body 131 in the short side direction. This is because, when the length H2 of the first through-hole portion 134 in the Y direction exceeds 2/3 of the length H1 of the main body portion 131 in the short side direction, the strength of the first shutter 130 becomes too low, which may result in a shortened life of the first shutter 130.

The second baffle 140 has practically the same constitution as the first baffle 130. Therefore, the description of the second baffle 140 is omitted with reference to the first baffle 130.

As shown in fig. 5, bearing portions 104 (only one is shown in fig. 5) are provided at four corners of the inner surface of the front surface side of the apparatus main body 110. By supporting the respective rotation shaft portions 135 of the first shutter 130 and the second shutter 140 by the bearing portions 104, each of the first shutter 130 and the second shutter 140 can pivot about the corresponding rotation shaft portion 135.

Further, in a plan view seen in the Y direction, the bearing portion 104 is not parallel to each of a pair of side surfaces opposite to the Z direction of the device main body 110, but forms an acute angle with respect to each of the pair of side surfaces, and extends in a direction approaching the center line CL1 in the short side direction of the device main body 110 from one side surface toward the other side surface. Thereby, each of the first and second shutters 130 and 140 becomes easy to move to the outside in the circumferential direction of the inner slot 30 (i.e., the direction in which the first and second side hole portions 114 and 115 are closed, respectively) by its own weight.

As shown in fig. 5, the cover 120 has a substantially rectangular plate shape covering the back face opening portion 111 of the apparatus main body 110, wherein one end in the long-side direction (i.e., the lower end in the Z direction) is pivotably supported by the cover support portion 112 of the apparatus main body 110, and the back face opening portion 111 can be opened and closed.

A pair of fixing claw portions 121 for fixing the cover body 120 to the apparatus main body 110 are provided at each corner of the other end (i.e., the upper end in the Z direction) in the longitudinal direction of the inner surface (i.e., the surface opposed to the apparatus main body 110) of the cover body 120.

In addition, the inner surface of the cover 120 is provided with a peripheral wall portion 122 protruding toward the apparatus main body 110. The peripheral wall 122 is provided along the inner peripheral edge of the rear opening 111 of the apparatus main body 110, and the outer side surface thereof is arranged to be in contact with part of the inner peripheral surface of the two inner side surfaces in the X direction, the upper inner side surface in the Z direction, and the lower inner side surface in the Z direction of the apparatus main body 110.

A rib 123, which is an example of a partition, extending in the longitudinal direction of the plate surface of the lid 120 is provided at the center of the inner surface of the lid 120. The rib 123 is provided inside the trap chamber 102 in a state where the rear opening 111 of the device main body 110 is closed by the cover 120, extends from one end to the other end of the trap chamber 102 in the longitudinal direction of the device main body 110 along the inner peripheral surface of the peripheral side portion 302 of the inner tank 30 and along the direction intersecting the circumferential direction of the inner tank 30 (i.e., the Z direction), is arranged at a position opposing the first side hole portion 114 and the second side hole portion 115 of the device main body 110, and partitions between the first side hole portion 114 and the second side hole portion 115.

In detail, as shown in fig. 8, the ribs 123 are arranged at intervals along the extending direction (i.e., Z direction) of the ribs 123, and have a plurality of plate-shaped protrusions 124 protruding from one side toward the other side in the direction (i.e., Y direction) intersecting with the inner peripheral surface of the inner groove 30 on the inner surface facing the trap chamber 102 of the housing 101, and gaps 125 are provided between the adjacent protrusions 124. In the first embodiment, the length W3 of the gap 125 in the extending direction of the rib 123 is set to 2mm, and the length W4 of the protrusion 124 in the extending direction of the rib 123 is set to 4 mm. That is, the length W3 of the gap 125 in the extending direction of the rib 123 is 1/2 of the length W4 of the protrusion 124 in the extending direction of the rib 123. The length H4 in the Y direction of the gap 125 is 2/3 of the length H3 in the short side direction of the plate surface of the rib 123.

Further, it is preferable that the length H4 in the Y direction of the gap 125 is 1/2 of the length H3 in the short side direction of the plate surface of the rib 123 (that is, the height of the rib 123). This is because, if the length H4 in the Y direction of the gap 125 does not reach 1/2 of the length H3 in the short side direction of the plate surface of the rib 123, the amount of the washing water that can pass through the gap 125 becomes small, and there is a possibility that the washing water that flows into the inside of the trap chamber 102 does not smoothly flow over the entire trap chamber 102.

In addition, the rib 123 has an inflow water guide 126. The inflow water guide portions 126 are disposed at the base end portions of the cover 120 near both end portions in the protruding direction of each protrusion 124, and extend in a direction (i.e., Z direction) intersecting the protruding direction of the protrusion 124. The washing water having flowed into trap chamber 102 from the outside of casing 101 through first side hole 114 and second side hole 115 of device body 110 is guided to the outside of casing 101 through front hole 103 by inflow water guide unit 126.

Next, the operation of the lint picker 100 will be described.

As shown in fig. 9, when the stirring blade rotates counterclockwise (hereinafter, referred to as a forward direction) as viewed from the upper opening 303 side in the height direction of the inner tub 30, a forward flow of the washing water is generated inside the inner tub 30. By this forward flow of the washing water, the first baffle 130 rotates and is pushed into the interior of the trap chamber 102. Thereby, the first side hole 114 is opened, and the washing water flows into the inside of the trap chamber 102 through the first side hole 114.

A part of the washing water flowing into the inside of the trap chamber 102 flows toward the inner tank 30 in a radial direction thereof by the inflow water guide portion 126 of the rib 123.

The washing water flowing toward the inner tub in the radial direction of the inner tub 30 through the inflow water guide 126 of the rib 123 flows out of the trap chamber 102 with respect to the rib 123 to the outside of the housing 101 through the front hole part 103 on the first side hole part 114 side, or flows out of the housing 101 through the front hole part 103 on the second side hole part 115 side through the gap 125 of the rib 123 since the second side hole part 115 is closed by the second barrier 140. At this time, lint contained in the washing water is removed by the protrusion 124 when passing through the gap of the rib 123, and is removed by the screen of the front hole 103 when flowing out of the trap chamber 102 to the outside of the housing 101, and is trapped inside the trap chamber 102.

In addition, a portion of the washing water passing through the gaps 125 of the ribs 123 and flowing toward the second baffle 140 flows out of the trap chamber 102 to the outside of the housing 101 via the second through-hole portion 144 of the second baffle 140. This flow toward the second shutter 140 presses the second shutter 140 from the trap chamber 102 toward the outside of the housing 101, and closes the second side hole portion 115. At this time, lint contained in the washing water is removed by the body portion 141 of the second barrier 140 and captured into the trap chamber 102 while passing through the second through-hole portion 144.

On the other hand, as shown in fig. 10, when the stirring blade 2 rotates clockwise (hereinafter referred to as reverse direction) as viewed from the upper opening 303 side in the height direction of the inner tub 30, a reverse flow of the washing water is generated inside the inner tub 30. By this reverse flow of the washing water, the second baffle 140 rotates and is pushed into the inside of the capturing chamber 102. Thereby, the second side hole part 115 is opened, and the washing water flows into the inside of the catching chamber 102 through the second side hole part 115.

A part of the washing water flowing into the inside of the trap chamber 102 flows toward the inner tank 30 in a radial direction thereof by the inflow water guide portion 126 of the rib 123.

The washing water flowing toward the inner tub in the radial direction of the inner tub through the inflow water guide 126 of the rib 123 flows out of the trap chamber 102 with respect to the rib 123 to the outside of the housing 101 through the front hole 103 of the second side hole 115 side, or flows out of the housing 101 through the front hole 103 of the first side hole 114 side through the gap 125 of the rib 123 since the first side hole 114 is closed by the first shutter 130. At this time, lint contained in the washing water is removed by the protrusion 124 when passing through the gap of the rib 123, and is removed by the screen of the front hole 103 when flowing out of the trap chamber 102 to the outside of the housing 101, and is trapped inside the trap chamber 102.

In addition, a portion of the washing water passing through the gap of the rib 123 and flowing toward the first baffle 130 flows out of the trap chamber 102 to the outside of the housing 101 through the first through hole part 134 of the first baffle 130. This flow toward the first shutter 130 presses the first shutter 130 from the trap chamber 102 toward the outside of the housing 101, and closes the first side hole portion 114. At this time, lint contained in the washing water is removed by the body portion 131 of the first barrier 130 and captured inside the trap chamber 102 while passing through the first through hole 134.

In this way, in washing machine 1, rib 123 partitioning between first side hole 114 and second side hole 115 is provided inside trapping chamber 102 of lint trapping device 100, and rib 123 has a plurality of protrusions 124 provided with gaps 125 between adjacent ones. This makes it possible to smoothly distribute the washing water flowing into the trap chamber 102 from the one-side hole portion over the entire trap chamber 2 and to reliably trap lint contained in the inflowing washing water, thereby realizing the washing machine 1 having high trapping performance for lint contained in the washing water.

In addition, the first shutter 130 is provided with a first through hole 134 penetrating the first shutter 130 in the rotation direction of the first shutter 130 at least in a portion covering the first side hole 114, and the second shutter 140 is provided with a second through hole 144 penetrating the second shutter 140 in the rotation direction of the second shutter 140 at least in a portion covering the second side hole 115. Accordingly, compared to a washing machine including a lint trap device in which the first and second through holes 134 and 144 are not formed in each of the first and second baffles 130 and 140, the amount of wash water flowing into the trap chamber 102 can be increased, and thus, the lint trap performance of lint contained in the wash water can be improved. As a result, the washing machine 1 having high trapping performance for lint contained in the washing water can be realized.

The first through hole portion 124 has a slit shape extending in a direction intersecting the extending direction of the rotation axis of the first shutter 130, and the second through hole portion 144 has a slit shape extending in a direction intersecting the extending direction of the rotation axis of the second shutter 140. Accordingly, since the amount of the washing water passing through the first through hole 134 and the second through hole 144 can be increased, the lint trapping performance in the washing water can be improved. As a result, the washing machine 1 having high trapping performance for lint contained in the washing water can be realized.

In addition, the rib 123 extends in a direction intersecting the protruding direction of the protrusion 124, and has an inflow water guide portion 126 that guides water flowing into the trap chamber 102 from the outside of the case 101 via the first side hole portion 114 and the second side hole portion 115 to the outside of the case 101 via the front hole portion 103. Accordingly, the washing water flowing into the inside of the capturing chamber 102 from the first and second side hole parts 114 and 115 smoothly spreads throughout the capturing chamber 102, and the water is guided to the front hole part 103 where smaller lint can be easily captured by the screen, so that lint contained in the inflowing washing water can be more reliably captured. As a result, the washing machine 1 having high trapping performance for lint contained in the washing water can be realized.

In addition, a curved surface 118 that is curved along the peripheral side portion 302 of the inner tank 30 in the circumferential direction of the inner tank 30 is provided at the front surface of the apparatus main body 110. Accordingly, since the flow of the washing water in the inner tub 30 can be made smooth and the amount of the washing water flowing into the catching chamber 102 of the lint catching device 100 can be increased, the lint catching performance included in the washing water can be improved. As a result, the washing machine 1 having high trapping performance for lint contained in the washing water can be realized.

The partition is not limited to one rib 123, and may be formed of a plurality of ribs. In this case, the plurality of ribs may extend in the longitudinal direction of the plate surface of the lid 120, for example, and may be arranged at intervals in the short-side direction of the plate surface of the lid 120. The plurality of protrusions 124 of the rib 123 are not limited to the plate shape, and may be, for example, a cylindrical shape.

In addition, in the lint trap apparatus 100 according to the first embodiment, the rib 123 is formed by the plurality of protrusions 124, and the first and second shutters 130 and 140 are each provided with the first and second through- hole portions 134 and 144, but the invention is not limited thereto. For example, the lint trap 100 may be configured by the rib 123 including the plurality of protrusions 124, the first and second shutters not provided with the first and second through-hole portions, the first and second shutters 130 and 140 provided with the first and second through- hole portions 134 and 144, respectively, and the rib of one plate-shaped member, or only the first and second shutters 130 and 140 provided with the first and second through- hole portions 134 and 144, respectively.

In addition, in the washing machine 1, the rib 123 is provided on the cover 120, but the present invention is not limited thereto, and the rib 123 may be provided on the apparatus main body 110.

The rib 123 may face the first side hole 114 and the second side hole 115, and is not limited to the case where it extends from one end to the other end of the trap chamber 102 in the longitudinal direction of the apparatus main body 110. Similarly, each of the first shutter 130 and the second shutter 140 may cover at least the first side hole portion 114 and the second side hole portion 115, and is not limited to the case where the first shutter extends from one end to the other end of the trap chamber 102 in the longitudinal direction of the apparatus main body 110.

(second embodiment)

Preferably, the length W1 of the first through hole 134 in the extending direction of the rotation axis of the first flap 130 is equal to or greater than 1/5 and equal to or less than 1/3 of the length W2 between adjacent first through hole 134 in the extending direction of the rotation axis of the first flap 130, and the length W1 of the second through hole 144 in the extending direction of the rotation axis of the second flap 140 is equal to or greater than 1/5 and equal to or less than 1/3 of the length W2 between adjacent second through hole 144 in the extending direction of the rotation axis of the second flap 140.

If the length W1 of the first through-hole 134 (or the second through-hole 144) does not reach 1/5 of the length W2 between the adjacent first through-holes 134 (or the second through-holes 144) in the extending direction of the rotation axis of the first flapper 130 (or the second flapper 140), the amount of the washing water that can pass through the first through-holes 134 (or the second through-holes 144) is reduced, and there is a possibility that the washing water that flows into the inside of the trap chamber 102 may not smoothly flow throughout the entire trap chamber 102. Further, if the length W1 of the first through-hole portion 134 (or the second through-hole portion 144) exceeds 1/3 of the length W2 between the adjacent first through-hole portions 134 (or the second through-hole portions 144) in the extending direction of the rotation axis of the first flapper 130 (or the second flapper 140), lint contained in the washing water passing through the first through-hole portions 134 (or the second through-hole portions 144) may not be sufficiently removed. Further, the strength of the first baffle 130 (or the second baffle 140) may be weakened, defects may easily occur in the first baffle 130 (or the second baffle 140), or the lifetime of the first baffle 130 (or the second baffle 140) may be shortened.

That is, by configuring such that the length W1 of the first through hole 134 (or the second through hole 144) in the extending direction of the rotation axis of the first flap 130 (or the second flap 140) is greater than or equal to 1/5 and less than or equal to 1/3 of the length W2 between adjacent first through holes 134 (or second through holes 144) in the extending direction of the rotation axis of the first flap 130, it is possible to smoothly distribute the washing water flowing into the inside of the capturing chamber 102 throughout the capturing chamber 102 and more reliably capture lint contained in the inflowing washing water.

(third embodiment)

Preferably, the length W3 of the gap 125 in the extending direction of the rib 123 is greater than or equal to 1/4 and less than or equal to 1/2 of the length W4 of the protrusion 124 in the extending direction of the rib 123.

If the length W3 of the gap 125 in the extending direction of the rib 123 does not reach 1/4 of the length W4 of the protrusion 124 in the extending direction of the rib 123, the amount of the washing water that can pass through the gap 125 becomes small, and there is a possibility that the washing water that flows into the inside of the trap chamber 102 may not smoothly flow throughout the trap chamber 102. Further, if the length W3 of the gap 125 in the extending direction of the rib 123 exceeds 1/2 of the length W4 of the protrusion 124 in the extending direction of the rib 123, lint contained in the washing water passing through the gap 125 may not be sufficiently removed.

That is, by configuring the length W3 of the gap 125 in the extending direction of the rib 123 to be equal to or greater than 1/4 and equal to or less than 1/2 of the length W4 of the protrusion 124 in the extending direction of the rib 123, the washing water flowing into the inside of the trap chamber 102 from the one hole portion can be smoothly distributed over the entire trap chamber 102, and lint contained in the inflowing washing water can be more reliably captured.

(fourth embodiment)

At least one of the gaps 125 of the rib 123 is arranged so as not to overlap at least one of the first through-hole 134 of the first baffle 130 and the second through-hole 144 of the second baffle 140 when viewed in the circumferential direction of the inner tub 30, and a flow path of the washing water flowing into the trap chamber 102 from one side hole and flowing out from the other side hole can be extended. This can improve the lint trapping performance of the wash water contained in the lint trap apparatus 100.

(fifth embodiment)

By disposing at least one of the first through-holes 134 of the first baffle 130 so as not to overlap the second through-holes 144 of the second baffle 140 when viewed in the circumferential direction of the inner tub 30, the flow path of the washing water flowing into the trap chamber 102 from one side hole to flow out from the other side hole can be extended. This can improve the lint trapping performance of the wash water contained in the lint trap apparatus 100.

(sixth embodiment)

The washing machine is not limited to the above embodiment as long as the lint trap device can be provided on the inner circumferential surface of the inner tub. For example, the inner tank is not limited to the "nonporous" type as in the above embodiment, and may be a "porous" type having a plurality of holes in the peripheral wall.

The various embodiments of the present invention have been described in detail above with reference to the drawings, and finally, various embodiments of the present invention will be described.

a partition 123 provided inside the trap chamber 102, extending in a direction intersecting the circumferential direction of the inner groove 30 along the inner circumferential surface of the inner groove 30 and disposed at a position opposing the first side hole portion 114 and the second side hole portion 115, and partitioning the first side hole portion 114 and the second side hole portion 115, the partition 123 having a plurality of protruding portions 124 protruding from one side toward the other side in the direction intersecting the inner circumferential surface of the inner groove 30 on the inner surface of the trap chamber 102 of the housing 101, with a gap 125 provided between the adjacent protruding portions 124.

According to the washing machine of the above embodiment, the rib 123 partitioning the first side hole part 114 and the second side hole part 115 is provided inside the capturing chamber 102 of the lint capturing device 100, and the rib 123 has the plurality of protrusions 124 provided with the gaps 125 between the adjacent ones. This makes it possible to smoothly distribute the washing water flowing into the trap chamber 102 from the one-side hole portion over the entire trap chamber 2 and to reliably trap lint contained in the inflowing washing water, thereby realizing the washing machine 1 having high trapping performance for lint contained in the washing water.
