[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lint catcher (lint filter) used in a washing machine and a washing machine including the same. In particular, the present invention relates to a washing machine provided with a stirring blade for stirring wash water and laundry on a side surface of a washing tub, and a lint catcher suitable for this washing machine.

[0002]

2. Description of the Related Art The applicant of the present application has proposed a washing machine having a structure in which a stirring wing is provided on a side surface of a washing tub (for example, Japanese Patent Application No. 7-224214).
issue). In such a washing machine, the planar shape of the washing tub can be rectangular with the side surface provided with the stirring blade as the long side surface. Utilizing this, a small washing machine that could not be realized with a conventional washing machine, for example, a narrow washing machine,
It is possible to realize a washing machine having a plurality of washing tubs within the width of a standard washing pan.

[0003] Further, regarding the capture of lint, etc. in the washing water,
The applicant of the present application, in the above-mentioned prior application, provides a circulating water passage communicating with the inside of the washing tub along the washing tub, causes the wash water in the circulating water passage to flow through the back blade of the stirring blade, and provides this flow in the circulating water passage. Proposed to lead to a lint filter. However, the size of the washing tub in the direction along the short side surface becomes large due to the circulating water channel and the back blade of the stirring blade. This increase in size leads to an increase in size in the width direction for the above-mentioned small washing machine, which is not preferable.

Further, the applicant of the present invention, in a washing machine having the same type of washing tub equipped with stirring blades on the side surface thereof, provides one opening on the short side surface of the washing tub to rotate the water flow in the washing tub. Has proposed a washing machine that takes in the water from the opening and guides it to the lint filter (for example, Japanese Patent Application No. 7-343240). However, in the case where the stirring blade repeats reversal every short time, the water flow rotating in the washing tub is weak, and it is feared that the thread waste and the like cannot be efficiently captured.

Further, there is a demand for a lint filter which can more effectively capture lint and the like even in a washing machine having a stirring blade on the bottom of a washing tub. Then, the objective of this invention is solving such a technical subject, and proposing the thread waste catcher which can capture a thread waste etc. efficiently, and a washing machine provided with the same.

[0006]

In order to achieve the above object, the washing machine of the invention according to claim 1 is attached to a washing tub of a washing machine, and wash water is flown into the washing machine to wash the threads in the washing water. In a yarn waste catcher that captures waste such as waste, a bag-shaped filter that can capture the yarn waste in the wash water flowing from the intake port, and the filter is detachably held,
A water inlet and a holder having a water channel for guiding the wash water from the water inlet to the inlet of the filter held by the water inlet are provided.
It is characterized in that it is opened in three different directions so that the wash water can flow in from three different directions.

According to this structure, during the washing operation of the washing machine, the washing water stirred by the rotating stirring blades flows in from the water inlet opened toward the three directions, passes through the water passage, and is filtered by the thread. Debris is captured. At this time, the lint catcher can take in the wash water flowing in from three different directions, so that the wash water can be efficiently introduced into the filter as compared with the case of taking in the wash water flowing in from one or two directions. Can be flowed in. Therefore, it is possible to efficiently capture the lint and the like.

According to a second aspect of the present invention, there is provided a lint catcher according to the first aspect, in which the holder is formed on the surface of the substrate, the substrate being substantially flush with the wall of the washing tub. The water inlet and the water channel are formed by the rib. According to this configuration,
In addition to the effect of the invention according to claim 1, the rib forms the water inlet and the water passage, so that the cleaning water flowing near the rib can be guided along the water passage. Therefore, the wash water can be flown through the filter more efficiently, and the thread waste and the like can be captured more efficiently.

A washing machine according to a third aspect of the present invention is provided with a washing tub for storing washing water and laundry and washing the washing tub, the washing tub being provided in the washing tub and being rotatable about a central axis. And a stirrer for stirring the laundry, and the lint catcher according to claim 1 or 2 provided in association with a side surface adjacent to an inner surface of a washing tub provided with the stirrer, The water inlet is
Includes three water inlets that are open to the inner wall of the washing tub in a crossing direction, one water inlet facing the stirring blade and the other two water inlets.
The two water inlets face in a direction substantially orthogonal to the one water inlet.

According to this structure, when the stirring blade rotates,
The washing water in the washing tub rotates and flows in the direction in which the stirring blade rotates in the washing tub, and also moves and moves away from the center along the radial direction of the stirring blade. These flows are directed in directions orthogonal to each other, and the direction of movement of the wash water corresponds to the direction of opening the water inlet. Therefore, the cleaning water efficiently flows into the water inlet, so that
Similar to the operation of the invention according to the first aspect, it is possible to efficiently flow into the filter, and it is possible to efficiently capture the thread waste and the like.

Further, since the cleaning water moving in the radial direction of the stirring blade moves away from the center regardless of the rotating direction of the stirring blade, the cleaning water can be efficiently used even when the stirring blade is repeatedly inverted. It can flow into the filter. As a result, it is possible to efficiently capture lint and the like. A washing machine according to a fourth aspect of the present invention is the washing machine according to the third aspect, wherein the filter is detachably mounted in the washing tub by sliding the filter in one direction intersecting a direction along the outer periphery of the stirring blade. It is characterized by that.

According to this structure, in addition to the function of the invention according to claim 3, since the filter is removable, cleaning and
If the filter is damaged, it can be easily repaired or replaced by removing it. Further, even if the laundry moves in a direction along the outer periphery of the stirring blade as the stirring blade rotates and comes into contact with the filter, the moving direction of the laundry and the sliding direction of the filter intersect with each other. Therefore, the filter does not easily slide with the movement of the laundry and is difficult to drop from the washing tub. Therefore, the filter can be stably installed in the washing tub and can more efficiently capture the lint and the like.

The washing machine of the invention according to claim 5 is the washing machine according to claim 3
Or in the washing machine according to 4, the washing tub has a pair of long side surfaces, a pair of short side surfaces, and a substantially rectangular planar shape partitioned by each side surface, and the stirring blade is centered on its central axis. Has a circular plate that rotates or rotates, and a protrusion that is provided on the surface of the circular plate, and is provided on the longitudinal side surface in the washing tub so that the central axis intersects with the longitudinal side surface. In the above, it is characterized in that it is provided near the position of the central axis of the stirring blade.

According to this structure, in addition to the function of the invention according to claim 3 or 4, since the yarn waste catcher is provided on the short side surface, the size of the washing tub along the short side surface can be increased. I don't have to. Further, since the holder is vertically close to the position of the central axis of the stirring blade, it can approach the outer circumference of the stirring blade, so that the water flow moving in the radial direction of the stirring blade was released toward the stirring blade. It can efficiently flow into the waterway from the water inlet portion. Therefore, it is possible to efficiently capture the lint and the like.

According to a sixth aspect of the present invention, there is provided a washing machine in which a stirring wing for rotating and stirring laundry and wash water is provided on a side surface of a washing tub. Three water inlets provided on a side surface adjacent to the side surface of the washing tub, into which wash water flows, and a water passage formed inside the side surface of the washing tub, which allows the wash water flowing from the three water inlets to circulate,
Wash water flows into the washing tub from three sides through the water passage and flows out into the washing tub. An outlet provided in the center of the side of the washing tub and a thread in the washing water that is attached to the outlet and flows in from the intake. Equipped with a bag-shaped filter that can capture scraps,
The water inlet is formed larger than the outlet.

According to this structure, 3 points from the center.
The three water inlets arranged on one side can flow the washing water in the vicinity of the side surface of the washing tub from a wide range to the filter through the water passage and the outlet, and can capture the lint and the like. Therefore, as compared with the case where the wash water flows in from one or two water inlets, the thread waste and the like can be efficiently captured. In addition, since the water inlet is larger than the outlet, the wash water can be taken in efficiently from the inside of the washing tub, and the filter can capture the thread waste and the like more efficiently. In addition, the water passage does not protrude into the washing tub, so that it is possible to maintain the cloth wrapping property of the laundry to be high.

A lint filter 27 is provided on the inner wall surface of the inner tub 22, and unnecessary substances such as lint in the wash water (hereinafter referred to as “yarn litter”) can be captured during washing.

The sub-washing device 40 has a substantially rectangular inner shape in plan view and has a washing tub 41 for storing washing water and laundry therein, and agitating the washing and washing water in the washing tub 41. In order to do so, a rotating shaft 46 as a central shaft is provided perpendicularly to the long side surface 41b of the washing tub 41, and the stirring blade 42 has a disc shape and the surface of which is formed in an uneven shape, and the stirring blade 42 is washed and rinsed. It is provided with a drive mechanism 43 for rotating it in one direction or both directions sometimes, and a lint filter 70 for capturing thread waste in the wash water during washing and rinsing.

The drive mechanism 43 includes a motor 44 as a drive source for rotating the stirring blade 42, a small pulley 49 for transmitting the rotation of the motor 44, a belt 48, and a large pulley 4.
7 and the rotating shaft 46 described above. Motor 44
The rotation of the stirring blade 42 is reduced by the belt 48 and the like.

The washing water and the laundry stored in the washing tub 41 are stirred by the stirring blade 42. At this time, the laundry is washed by the water flow and by friction with the stirring blade 42 and the inner surface of the washing tub 41, and is similarly rinsed. Hereinafter, each part will be described in detail. The washing tub 41 has a long side surface 41b along the left side surface of the housing 10 and is arranged long in the front-rear direction, and is formed in a container shape with an open top.

The washing tub 41 has a bottom surface 41a and a bottom surface 41a.
And a pair of opposing long side surfaces 41b and 41c and a pair of opposing short side surfaces (the rear side is referred to as a short side surface 41d), which are side surfaces rising from the surroundings. Each side surface is provided substantially perpendicular to the bottom surface 41a. Bottom 41
The a has a concave curved surface on its front and rear portions, and is connected to both short side surfaces via the concave curved surface. Therefore, the bottom surface 41
The a can guide the water flow accompanying the rotation of the stirring blade 42 without stagnation, and can maintain the cleaning effect without weakening the water flow.

Further, in the washing tub 41, a prescribed water level H is set which regulates the amount of washing water stored inside. At the specified water level H, the washing water is sufficiently stored in the washing tub 41,
It is set corresponding to a standard amount of wash water that can stir laundry in wash water, and for example, the rotation shaft 46 is set to be located near the center between the prescribed water level H and the bottom surface 41a in the vertical direction. .

The lint filter 70 has a short side surface 41d,
It is provided at almost the same position as the rotary shaft 46 in the vertical direction. FIG. 2 is an exploded perspective view of the lint filter 70 shown in FIG. FIG. 3 is a partial cross-sectional front view of the sub-washing device 40 near the lint filter 70. FIG. 4 is a cross-sectional plan view of the lint filter 70 shown in FIG. FIG.
FIG. 4 is a left side view of the lint filter 70 shown in FIG. 3 taken along the line BB. This will be described with reference to FIGS.

As shown in FIG. 2, the lint filter 70 includes a filter body 71 capable of capturing and accumulating thread waste and the like, and a holder 72 for attaching the filter body 71 to the inner wall of the washing tub. . The filter body 71 is
A net member 75 as a filter and a frame member 76 for holding the net member 75 are provided.

The holder 72 detachably holds the frame member 76 of the filter body 71 in the washing tub 41. Further, the holder 72 has a function of guiding the wash water to the filter body 71. That is, the holding body 72 has the filter body 7
As shown in FIG. 3, with the 1 attached, openings as water inlets facing the inside of the washing tub 41, that is, a first opening 81, a second opening 82, and a third opening 83,
A water passage 84 communicating with each opening and reaching the net member 75 is formed. As will be described later in detail, the wash water is washed in the washing tub 4
From the inside of 1 through each opening and the water passage 84 to reach the net member 75, where thread wastes and the like are efficiently captured.

The holding body 72 is provided with a rectangular plate-shaped mounting plate portion 72a as a substrate mounted on the short side surface 41d and a projecting portion 72b projecting forward from the mounting plate portion 72a, and is made of a resin such as plastic. It is formed integrally. The mounting plate portion 72a is arranged substantially flush with the short side surface 41d of the washing tub 41, and the front surface thereof forms a part of the short side surface 41d. Further, the projecting portion 72b is formed in an X shape in a front view along the mounting plate portion 72a. The central portion of the overhanging portion 72b is formed in a hollow shape, and the upper, lower, left, and three sides thereof are open to partition the above-described openings. The overhanging portion 72b includes a plurality of radially extending rib-shaped guide guides 72h,
A V-shaped rib 72c formed in the center hollow portion in a front view, and a recessed portion 72f in the front portion, which is arranged so as to face each other for attaching the filter main body 71 and extends in one direction. Is equipped with.

The guide guide 72h has a short side surface 4 from each opening.
It extends in a direction diagonally intersecting with the flow direction in the vicinity of 1d, and the flow of cleaning water in the vicinity can be guided along each flow to each opening. Therefore, the cleaning water can efficiently flow into the opening, and the unwanted substances can be captured more efficiently. Further, the guide guides 72h form each opening and are arranged in pairs on both sides of each opening, and can guide the wash water flowing in a wide range to each opening. For example, above the first opening 81, there is a pair of guide guides 72h that widen upward, and the guide guides 72h follow the wash water flowing from above and follow the first opening 81 that is narrower and opens upward. Can be flowed in. Therefore, the unwanted matter can be efficiently captured.

Further, the guide guide 72h is designed so that as it approaches the peripheral portion of the holding body 72, the amount of forward projection from the mounting plate portion 72a decreases, and the cross section orthogonal to the extending direction is substantially triangular. It is formed in a shape. The cross-section is formed by an inclined surface having a rounded top located at the front, and the inclined surface and the mounting plate portion 72a are smoothly connected. Therefore, the guide guide 72h can prevent the laundry that is stirred in the washing tub 41 from being damaged even if the laundry touches the lint filter 70. Further, since the guide guide 72h does not hinder the flow of washing water or laundry in the washing tub 41, the washing power can be kept high. Further, since the guide guide 72h can prevent the laundry from closing each opening, it is possible to prevent the efficiency of capturing the yarn waste and the like from being lowered.

The first opening 81 is formed in the protruding portion 72 of the holder 72.
The upper surface of the central portion of b is open upward. Therefore, as will be described later, it is possible to receive a water flow that rotates clockwise in a right side view around the rotation shaft 46. The second opening 82 is opened downward on the lower surface of the central portion of the protruding portion 72b of the holding body 72. Therefore, as will be described later, it is possible to receive a water flow that rotates counterclockwise in a right side view around the rotation shaft 46.

The third opening 83 is defined by both left side surface portions of the holding body 72 and the filter body 71, and opens to the left. Therefore, as described later, it is possible to receive the water flow moving away from the center along the radial direction of the stirring blade 42. The water passage 84 is connected to each opening, and is defined by the central portion of the overhanging portion 72b of the holding body 72 and the later-described central hole of the frame member 76.

The rib 72c is provided in the water passage 84 with the mounting plate 7
It is provided upright from 2a, forms a part of the water passage 84, and functions as a partition member that suppresses the flow of wash water between the openings. The rib 72c includes a first portion between the first opening 81 and the third opening 83, a second opening 82, and a third portion.
A second portion between the opening 83 and the second portion. First
The part limits the flow of cleaning water between the first opening 81 and the third opening 83, and the second part restricts the flow of cleaning water between the second opening 82 and the third opening 83. To do. in this way,
The ribs 72c can prevent the wash water from entering the one opening and then flowing out from the other openings as they are, so that the wash water can be efficiently introduced into the mesh member 75 from each opening. Therefore, the lint and the like can be captured more efficiently. Further, the rib 72c is formed to be approximately equal to the dimension of each opening in the front-rear direction so that the flow of washing water between the openings can be surely restricted. Also, the rib 72c
Is attached to a section orthogonal to the extending direction of the mounting plate 72a.
Has a concave curved portion 72d that smoothly connects with the concave curved portion 72d. Since the concave curved portion 72d can smoothly guide the wash water that has flowed in along the mounting plate portion 72a to the front side, the wash water passes through the water passage 84. It can be efficiently distributed inside, and as a result, unwanted substances can be captured even more efficiently. The concave curved portion 7
Instead of 2d, the cross section may be formed in an inclined shape.

The frame member 76 is a plate member having a central hole as a part of the water passage 84, and the recesses 72 are formed at the upper end and the lower end.
A convex portion 76b that fits with f is formed. Net member 75
Is a bag-shaped net with fine holes of a size that allows passage of washing water and blocks passage of lint, with one end opened as an intake port and the other end closed. Yes,
This is a known configuration. The mesh member 75 is attached to the peripheral portion of the central hole of the frame member 76 in a state where the bag inlet is opened. The washing water that flows in from the intake port passes through the fine holes and flows out, while the thread waste that has flowed into the bag together with the washing water is stored in the bag.

Further, since the mesh member 75 is provided in the washing tub 41 in the form of a flexible bag, it is bent at the central portion in accordance with the water flow in the washing tub 41, so that the lint and the like inside flows back. Can be prevented. Further, the mesh member 75 can be attached and detached as follows. Inside the concave portion 72f, the convex portion 76b of the frame member 76 to which the mesh member 75 is attached is inserted in a fitted state, and the concave portion 72f slidably guides the filter main body 71 in the extending direction and at the time of washing. The water main body 71 holds the filter body 71 so that the filter body 71 does not inadvertently drop from the recess 72f. The recess 72f is open at the left end and closed at the right end. The frame member 76 can be set by inserting the frame member 76 from the left end of the recess 72f until the frame member 76 contacts the contact portion 72g. Frame member 76
Can be removed by sliding it in the opposite direction.

As described above, since the filter main body 71 is removable, the mesh member 75 can be easily cleaned by removing it. Further, the detachable filter body 71 can be easily repaired or replaced when damaged. Also,
Since the sliding direction (horizontal direction) of the frame member 76 intersects with the rotating water flow direction (vertical direction) as described later, the frame member 7 moves as the laundry moves with this water flow.
6 does not slide easily, and the mesh member 75 is stably attached inside the washing tub 41. In particular, since both directions are orthogonal to each other, the frame member 76 does not slide due to the laundry, and the attached state of the net member 75 is further stable. Further, as shown in FIG. 3, the direction of sliding to remove the frame member 76 (from right to left, arrow R) is opposite to the direction of the water flow flowing in the radial direction (from left to right, arrow G3). Therefore, the frame member 76 does not slide even when receiving a water flow, and the attached state of the mesh member 75 is further stable. Therefore, the net member 75 can be stably attached to the washing tub 41, and the yarn waste and the like can be captured more efficiently.

Next, the operation of the sub-washing device 40 will be described.
During washing and rinsing, the stirring blade 42 repeats normal rotation and reverse rotation at a predetermined rotation speed and at a predetermined time interval. At the same time, the washing water is washed in the same direction as the rotating direction of the washing tub 4.
The stirring blade 42 moves in the radial direction of the stirring blade 42, and at the same time, moves toward the outer periphery in the radial direction of the stirring blade 42. The wash water thus moving flows into each opening.

As shown in FIG. 3, when the stirring blade 42 rotates in the clockwise direction when viewed from the right side surface, the rotationally moving cleaning water moves from top to bottom along the short side surface 41d (arrow G).
1), a part thereof flows into the first opening 81 along the guide guide 72h. The wash water flowing into the first opening 81 is
The water passage 84, that is, the frame member 76 from the inside of the overhanging portion 72b.
Through the center hole (arrow G4 in FIG. 5) to reach the mesh member 75. The net member 75 efficiently captures thread wastes and the like in the wash water. After that, the cleaning water from which the thread wastes have been removed is removed by the mesh member 75.
And returns to the inside of the washing tub 41.

As shown in FIG. 4, the cleaning water moving in the radial direction flows from the front part to the rear part of the rear portion of the long side surface 41b,
Then, the short side surface 41d is moved from left to right (arrow G3),
It flows into the third opening 83. The wash water reaches the net member 75 from the third opening 83 through the water passage 84 (arrow G5), and the thread waste and the like are efficiently captured. On the other hand, when the stirring blade 42 rotates in the opposite direction (counterclockwise direction when viewed from the right side surface),
As shown in, the cleaning water that rotates and moves moves from the bottom to the top along the short side surface 41d (arrow G2) and flows in from the second opening 82. The cleaning water moving in the radial direction flows into the third opening 83 as described above (arrow G3). The wash water reaches the net member 75 from both openings through the water passage 84 (arrows G5 and G6 in FIG. 5), and the thread waste and the like are efficiently captured.

As described above, according to the present embodiment, regardless of the rotating direction of the stirring blade 42, the radial water flow and the rotating water flow can be introduced from the three openings and used together, so that thread waste and the like can be collected. It can be captured efficiently. further,
By guiding the wash water by the guides 72h and the ribs 72c, it is possible to capture the thread waste and the like more efficiently.

Further, since each opening is provided in accordance with the direction of the water flow in the washing tub 41, the guide guide 72h and the like can be set in an appropriate shape according to the direction of the water flow, and the water flow can efficiently flow into each opening. Can be made. Therefore, the lint and the like can be captured more efficiently. Also, since each opening is opened in three different directions, 1 or 2
Compared to the case of taking in the wash water flowing in from
Further, as compared with the case where the cleaning water flows in through the 1 or 2 openings, the thread waste and the like can be efficiently captured.

Further, depending on the setting of the washing method, the stirring blade 42 may be inverted at short time intervals, and the laundry or washing water in the washing tub 41 may not be sufficiently rotated. Particularly, in the sub-washing device 40 of the two-tub type washing machine that can be separately washed, it is assumed that there are many occasions to wash only soft clothes that are not preferable to be mixed with standard laundry, and the above-described cases where the clothes do not rotate sufficiently To be done. Even in such a case, the stirring blade 42
Since the cleaning water moving in the radial direction moves toward the outer periphery regardless of the rotation direction of the stirring blade 42, the cleaning water can efficiently flow into the mesh member 75 from the third opening 83. As a result, it is possible to efficiently capture lint and the like.

Further, the lint filter 70 includes the stirring blade 42.
Is provided on the short side surface 41d of the washing tub 41 provided on the side surface, the width dimension of the washing tub 41 is not increased, and the sub-washing device 40 and the washing machine 1 can be downsized. Therefore, it is preferable to realize a washing machine which has sufficient washing ability and can be separately washed so that the width can be accommodated in the size of a domestic washing pan.

In particular, the third opening 83 is located at a position substantially equal to the stirring blade 42 in the height direction, so that the short side surface 41
Since it can be provided closest to the outer periphery of the stirring blade 42 at d, the third opening 83 can take in a strong water flow close to the stirring blade 42, and as a result, the thread waste and the like can be captured more efficiently. Further, even when the water level is about the height of the rotary shaft 46, each opening is near the height of the rotary shaft 46, and the wash water can flow into the opening and trap unnecessary substances.

By the way, the lint filter 70 described above is used.
The lint filter 27 is applied to the main washing device 20 having the stirring blades 23 on the bottom surface of the washing tub. The lint filter 27 includes an arrangement of openings of the lint filter 70,
The sliding direction of the filter body 71 is different. Each of the openings in the lint filter 27 opens in three directions along the inner surface of the inner tank 22, for example, facing left, right, and downward in FIG. Therefore, the rotational flow (arrows H1 and H2) by the stirring blade 23 and the radial flow (arrow H3) can be introduced from each opening. In addition, the lint filter 27
Is disposed near the bottom surface of the inner tank 22 and is close to the stirring blade 23, so that the radial flow can be introduced more efficiently.

Further, the filter main body 71 of the lint filter 27 is set by sliding from top to bottom and is removed by sliding from bottom to top. Next, a second embodiment will be described.
