The arrangement of the plurality of hair bundles 64 in this embodiment will be detailed later.

(Outline description of operation of washing machine 1)
Next, an outline of operation of the washing machine 1 will be described.

(Washing of laundry 70)
The article 70 to be washed 70 is washed in a state in which the article 70 to be washed, such as footwear, is fixed to the holder and detergent and water are stored in the washing tub 12 . Of the agitator 13 and the washing tub 12 , only the agitator 13 is rotationally driven by the drive mechanism 50 to wash the laundry 70 . As a result, the brush 6 rotates relative to the laundry 70 fixed to the holder provided on the agitator 13 . As a result, the brush 6 comes into contact with the laundry 70, and the laundry 70 is washed. When the laundry 70 is washed, the washing tub 12 and the holder may be rotated relative to each other, and the washing tub 12 may be non-rotatable or rotatable with respect to the tub 11. It may be said that

(Dehydration of laundry 70)
After washing the article 70 to be washed, dehydration of the article 70 to be washed is optionally performed. Specifically, when the washing of the laundry 70 is completed, the detergent and water are discharged from the washing tub 12 via the drainage portion and the drain hole provided in the washing tub 12 . Next, the agitator 13 and the washing tub 12 are integrally rotationally driven by the drive mechanism. As a result, a centrifugal force acts on the laundry 70 fixed to the holder provided in the agitator 13, and the laundry 70 is dehydrated.

For example, when the article to be washed 70 is a shoe, it is preferable to fix the shoe to the holder part so that the opening of the shoe faces radially outward. By doing so, the water inside the shoe can be efficiently discharged to the outside.

FIG. 5 is a schematic diagram for explaining the arrangement of the plurality of hair bundles 64 in the first embodiment. FIG. 6 is a schematic diagram for explaining the contact between the bundle of hair 64 and the article to be washed 70 in the first embodiment. 5 and 6, the bristle bundles 64 when the brush 6 is viewed from the rotating shaft of the washing tub 12 are shown as "circle (○) ("circle (○) inscribed with a square (□)", "triangle (△ ) includes an inscribed circle (○).”)”. Next, the arrangement of the plurality of hair bundles 64 in the first embodiment will be described with reference to FIGS. 5 and 6. FIG.

As shown in FIG. 5, in the first embodiment, the first outer brush module 621, the second outer brush module 622, and the inner brush module 623 have different arrangement patterns of the plurality of bristle bundles 64 from each other.

Among the three brush modules 621, 622, and 623, the inner brush module 623 is located at the center (inner side) in the rotation direction R (including the forward rotation direction R1 and the reverse rotation direction R2) of the holder (washing tub 12). , the plurality of hair bundles 64 are arranged in a matrix along the rotation direction R and the rotation axis direction A of the holder portion (washing tub 12). Specifically, the plurality of bristle tufts 64 in the inner brush module 623 are arranged in a square matrix along the rotation direction R and the rotation axis direction A. As shown in FIG.

The number of rows and columns of the plurality of bristle tufts 64 in the inner brush module 623 is not particularly limited. The number of rows of the plurality of tufts 64 in the inner brush module 623 can be appropriately determined based on, for example, the expected size of the laundry 70, the diameter of the tufts 64, the arrangement pitch of the tufts 64, and the like. . The number of rows of the plurality of bristle tufts 64 in the inner brush module 623 can be, for example, about 10-100. The number of rows of the plurality of tufts 64 in the inner brush module 623 can be appropriately determined based on, for example, the expected size of the laundry 70, the diameter of the tufts 64, the arrangement pitch of the tufts 64, and the like. . The number of rows of the plurality of bristle tufts 64 in the inner brush module 623 can be, for example, about 3-100.

In each of the first outer brush module 621 and the second outer brush module 622 positioned outside in the rotation direction R among the three brush modules 621, 622, and 623, the plurality of bristle tufts 64 are arranged along the rotation axis direction A. are arranged in a meandering pattern. Specifically, in each of the first outer brush module 621 and the second outer brush module 622, the plurality of bristle bundles 64 are arranged in a meandering manner along the rotation axis direction A (specifically, 2) hair bundle rows. The period of arrangement of the plurality of bristle bundles 64 in the first outer brush module 621 along the rotation axis direction A and the arrangement period of the plurality of bristle bundles 64 in the second outer brush module 622 along the rotation axis direction A are: , are shifted by half a period (π). Therefore, the arrangement of the plurality of bristle tufts 64 in the first outer brush module 621 and the arrangement of the plurality of bristle tufts 64 in the second outer brush module 622 are aligned with respect to the axis of symmetry extending along the rotation axis direction A. They have a symmetrical relationship.

Of the plurality of tufts 64 included in the brush 6, a plurality of tufts (rectangle A hair bundle group formed by a hair bundle represented by a circle (○) inscribed with (□) 64a is defined as a first adjacent hair bundle group 66a.

Among the plurality of tufts 64 included in the brush 6, a plurality of tufts (triangular A hair bundle group represented by a circle (○) inscribed with (Δ) 64b is defined as a second adjacent hair bundle group 66b.

As shown in FIG. 6, the first adjacent hair bundle group 66a and the second adjacent hair bundle group 66b are hair bundle groups each composed of a plurality of hair bundles adjacent to the laundry 70 in the rotation direction R. . That is, the first adjacent hair bundle group 66a and the second adjacent hair bundle group 66b are each composed of a plurality of hair bundles 64 that first come into contact with the rotating laundry 70 among the plurality of hair bundles 64. It is a group of hair bundles. Specifically, the first adjacent hair bundle group 66a is a hair bundle group constituted by a plurality of hair bundles 64a adjacent to the laundry 70 in the forward rotation direction R1 among the plurality of hair bundles 64. As shown in FIG. That is, the first adjacent tuft group 66a includes, among the plurality of tufts 64, the plurality of tufts that first come into contact with the laundry 70 rotating from the downstream side r1 toward the upstream side r2 in the normal rotation direction R1. 64a is a hair bundle group. The second adjacent hair bundle group 66b is a hair bundle group constituted by a plurality of hair bundles 64b adjacent to the laundry 70 in the reverse direction R2 among the plurality of hair bundles 64. As shown in FIG. That is, the second adjacent tuft group 66b includes, among the plurality of tufts 64, the plurality of tufts 64b that first come into contact with the laundry 70 rotating from the upstream side r2 toward the downstream side r1 in the reverse direction R2. It is a hair bundle group composed of Here, "first contact" means first contact among the plurality of tufts 64 arranged along the rotation direction R. As shown in FIG.

The first adjacent hair bundle group 66a and the second adjacent hair bundle group 66b are each arranged along a first direction (for example, oblique left direction in FIGS. 5 and 6) inclined with respect to the rotation direction R. and a plurality of hair tufts 64 that are inclined with respect to the rotation direction R and arranged along a second direction different from the first direction (for example, diagonally right direction in FIGS. 5 and 6). and tufts 64 of Specifically, the first adjacent hair bundle group 66a and the second adjacent hair bundle group 66b are arranged in a meandering manner along the rotation axis direction A, respectively.

By the way, for example, when the tufts included in the brush are arranged in a square matrix, a plurality of tufts forming the adjacent tuft group are linearly arranged along the rotation axis direction. Therefore, when the article to be washed rotates toward the brush, a plurality of tufts constituting adjacent tuft groups can come into contact with the article to be washed at the same time. Therefore, when the brush comes into contact with the laundry, a large impact is applied to the laundry. Therefore, the laundry is easily damaged.

On the other hand, in this embodiment, as shown in FIG. The tufts 64 are arranged to contact the laundry 70 at different times. Specifically, the first adjacent tuft group 66a rotates relative to the laundry 70a relative to the brush 6 from the upstream side r1 to the downstream side r2 in the forward rotation direction R1 at different timings. Arranged to include contacting tufts 64 . The second adjacent tuft group 66b hits the laundry 70 at different timings with respect to the laundry 70b that has rotated relative to the brush 6 from the upstream side r2 to the downstream side r1 in the reverse direction R2. Arranged to include contacting tufts 64 . Therefore, it is possible to prevent the plurality of hair bundles 64 forming the adjacent hair bundle groups 66a and 66b from coming into contact with the laundry 70 at the same time. Therefore, when the brush 6 comes into contact with the laundry 70, the impact applied to the laundry 70 can be reduced. Therefore, damage to the laundry 70 can be suppressed.

Only from the viewpoint of suppressing damage to the article to be washed 70, the adjacent hair bundle groups 66a and 66b do not include the hair bundles 64 that contact the relatively rotated article to be washed 70 at the same timing. It is considered preferable that all of the plurality of hair tufts 64 forming the tuft groups 66a and 66b come into contact with the laundry 70 at different timings. Specifically, for example, it is considered preferable to arrange the adjacent hair bundle groups 66a and 66b in a spiral. However, in that case, the central angle of the area where the brush is provided becomes large. Therefore, the space for arranging the laundry is restricted. Therefore, the number of articles to be washed that can be installed is reduced.

On the other hand, in the present embodiment, the adjacent tuft groups 66a and 66b are aligned with the laundry 70 fixed to the holder portion at the same timing when the laundry 70 is rotated relative to the brush 6. Arranged to include contacting tufts 64 . Therefore, the space for arranging the brushes 6 (range of central angles in which the brushes 6 are positioned) can be reduced. Therefore, the number of laundry items 70 that can be placed at one time can be increased. As described above, according to the washing machine 1 of the present embodiment, it is possible to clean a large number of laundry items 70 at once, and to suppress damage to the laundry items 70 during washing.

From the standpoint of increasing the number of laundry items 70 that can be selected at one time and more effectively suppressing damage to the laundry items 70 during washing, the first washing machine located on the upstream side r1 in the forward rotation direction R1 is recommended. The first adjacent hair bundle group 66a and the second adjacent hair bundle group 66b located on the upstream side r2 in the reverse direction R2 respectively contact the relatively rotated laundry 70 at different timings. It is preferably arranged to include both 64 and tufts of hair 64 that come into contact at the same time. More preferably, the adjacent tuft groups 66a, 66 each include a plurality of tufts 64 arranged along the first direction and a plurality of tufts 64 arranged along the second direction. More preferably, the adjacent hair bundle groups 66a and 66b are arranged in a meandering manner along the rotation axis direction A, respectively. In this case, damage to the laundry 70 can be suppressed both when the laundry 70 rotates in the forward rotation direction R1 and when it rotates in the reverse rotation direction R2.

In addition, in the present embodiment, when the tufts 64 and the article 70 to be washed come into contact with each other, the opposite side of the tufts 64 to the article 70 to be washed in the rotation direction R, one side and the other side in the rotation axis direction A There are many tufts 64 in which the tufts 64 are not adjacent in any of them. Such hair bundles 64 are less likely to be restricted in deformation by the adjacent hair bundles 64 and are more likely to be deformed. Therefore, damage to the laundry 70 due to contact with the tufts 64 can be suppressed. From the viewpoint of increasing the proportion of hair bundles 64 whose deformation is less likely to be restricted as described above, it is preferable that the hair bundle row composed of a plurality of hair bundles 64 arranged in succession be arranged in a meandering manner. .

Another preferred example of implementing the present invention will be described below. In the following description, members having substantially the same functions as those of the first embodiment will be referred to by common reference numerals, and descriptions thereof will be omitted.

(Second embodiment)
FIG. 7 is a schematic diagram for explaining the arrangement of hair bundles in the second embodiment. The washing machine according to the second embodiment differs from the washing machine according to the first embodiment in the arrangement pattern of the plurality of bristle bundles 64 of the brush 6, and the rest of the configuration is the same. Specifically, the second embodiment differs from the first embodiment only in the arrangement pattern of the plurality of bristle bundles 64 in the outer brush modules 621 and 622 . The arrangement pattern of the plurality of bristle bundles 64 in the outer brush modules 621 and 622 according to the second embodiment will be described below with reference to FIG.

In the first embodiment, as shown in FIG. 5, a plurality of tufts 64 (specifically, two tufts 64) are arranged adjacent to each other along the rotation direction R in the outer brush modules 621 and 622. I explained an example where In contrast, as shown in FIG. 7, in the second embodiment, the outer brush modules 621 and 622 do not have bristle tufts 64 that are adjacent in the rotational direction R. As shown in FIG. In other words, in the second embodiment, the positions in the rotation axis direction A of all the bristle tufts 64 of the outer brush modules 621 and 622 are different. In each of the outer brush modules 621 and 622, the direction in which two adjacent bristle tufts 64 are adjacent is the rotational axis direction A or a direction inclined with respect to the rotational direction R. Therefore, the plurality of tufts 64 of the outer brush modules 621 and 622 are all positioned on the opposite side of the tufts 64 from the laundry 70 in the rotational direction R when the bristle tufts 64 and the laundry 70 come into contact with each other. Hair tufts 64 are arranged so as not to be adjacent to each other. Therefore, when the bundle of hair 64 contacts the laundry 70, the deformation of the bundle of hair 64 is less likely to be restricted. Therefore, it is possible to more effectively suppress damage to the laundry 70 due to contact with the tufts of hair 64 .

However, since the detergency increases as the number of bristle bundles 64 in contact with various parts of the laundry 70 increases, from the viewpoint of improving the detergency of the washing machine, the arrangement of the plurality of bristle bundles 64 in the second embodiment The arrangement of the plurality of hair bundles 64 in the first embodiment is also preferable.

In the first embodiment, as shown in FIG. 5, in the outer brush modules 621 and 622, a tuft row consisting of a plurality of bristle tufts arranged in succession is arranged in a meandering pattern with a period greater than 1. I explained an example. On the other hand, in the second embodiment, as shown in FIG. 7, in the outer brush modules 621 and 622, the bristle bundle rows are arranged in a meandering pattern with a period of 1 or less (specifically, 1/2 period). ing. Even when the hair bundle rows are arranged in a meandering pattern with a period of 1 or less as in the second embodiment, the adjacent hair bundle groups 66a and 66b are rotated at different timings with respect to the rotating laundry 70. As long as it is arranged so as to include the tufts 64 in contact with each other, the impact applied to the laundry 70 when the bristle tufts 64 and the laundry 70 come into contact can be reduced. Therefore, damage to the laundry 70 can be suppressed.

(Third Embodiment)
FIG. 8 is a schematic diagram for explaining the arrangement of the hair bundles 64 in the third embodiment. The third embodiment differs from the first and second embodiments only in the arrangement pattern of the tufts 64 of the outer brush modules 621 and 622 . The arrangement pattern of the plurality of bristle tufts 64 in the outer brush modules 621 and 622 according to the third embodiment will be described below with reference to FIG.

As shown in FIGS. 5 and 7, in the first and second embodiments, in each of the outer brush modules 621 and 622, the plurality of bristle tufts 64 are arranged in succession. An example in which one configured hair bundle row is configured has been described. However, the present invention is not limited to this configuration.

As shown in FIG. 8, in the third embodiment, in the first outer brush module 621, the plurality of bristle bundles 64 form a plurality of bristle bundle rows 67a and 67b each including a part of the bristle bundles 64 in common. ing. The hair bundle row 67a and the hair bundle row 67b have a crossing portion where they cross each other. In the second outer brush module 622, the plurality of bristle bundles 64 form a plurality of bristle bundle rows 67c and 67d that share some of the bristle bundles 64 with each other. The hair bundle row 67c and the hair bundle row 67d have an intersection where they cross each other. In the third embodiment as well, as long as adjacent hair bundle groups 66a and 66b are arranged so as to include hair bundles 64 that come into contact with the rotating laundry object 70 at different timings, the hair bundles 64 and the laundry object 70 are separated from each other. It is possible to reduce the impact applied to the laundry 70 when it comes into contact with the. Therefore, damage to the laundry 70 can be suppressed.

In the third embodiment, the plurality of hair bundles 64 in each of the hair bundle rows 67a, 67b, 67c, and 67d are arranged so as to be positioned at different positions in the rotation axis direction A. As shown in FIG.
