[0030] Hereinafter, an example of a preferred embodiment of one embodiment of the present invention will be described. However, the following embodiments are merely examples, and one embodiment of the present invention is not limited to any of the following embodiments.

[0031] (First embodiment)

[0032] Figure 1 It is a schematic perspective view of the washing machine 1 according to the first embodiment. Figure 2 It is a schematic cross-sectional view of the washing machine 1 according to the first embodiment. Figure 3 1 is a schematic top view showing the main part of the washing tank 12 of the first embodiment. Figure 2 In the figure, among the plurality of brush modules 621, 622, 623, only the first outer brush module 621 and the second outer brush module 622 are schematically depicted. Figure 2 In the figure, the inner brush module 623 is omitted.

[0033] Figure 1 and Figure 2 The washing machine 1 shown is suitable for washing laundry 70 containing solid parts (see Figure 6 ). Examples of the laundry 70 including a solid portion include shoes, slippers, sandals, and other footwear. The washing machine 1 is not particularly limited as long as the laundry 70 can be washed, but it is preferred that the laundry 70 can be washed and dehydrated. That is, the washing machine 1 is preferably a washing and dehydrating machine.

[0034] (Schematic Structure of Washing Machine 1)

[0035] Reference Figure 1 and Figure 2 The schematic structure of washing machine 1 will be described.

[0036] like Figure 1 As shown, the washing machine 1 includes an outer box 10 , an upper part 20 , an upper cover 30 and a base part 40 .

[0037] like Figure 2 As shown in FIG. 1 , the outer box 10 is formed in a cylindrical shape with openings at the top and the bottom. The upper opening of the outer box 10 is connected to the upper member 20 . On the other hand, the lower opening of the outer box 10 is connected to the base member 40 .

[0038] The upper member 20 is provided with an opening 21 for taking out and putting in laundry 70. The opening 21 can be opened and closed by an upper cover 30 rotatably mounted on the upper member 20.

[0039] The outer box 10 includes a water tank 11. The water tank 11 is a substantially bottomed cylindrical shape with an upper opening. The opening of the water tank 11 is connected to the opening 21. A drain for draining water from the water tank 11 is provided at the bottom of the water tank 11.

[0040] A washing tank 12 is arranged in the water tank 11. The washing tank 12 is also in the shape of a cylinder with a bottom and an opening at the top, similar to the water tank 11. The washing tank 12 and the water tank 11 are arranged so that their rotation axes coincide with each other. The washing tank 12 can rotate relative to the water tank 11. A dehydration portion is formed at the bottom of the washing tank 12, and a plurality of drainage holes are formed at the uppermost portion of the peripheral wall of the washing tank 12, and no drainage holes are formed in other portions of the peripheral wall of the washing tank 12. However, the present invention is not limited to this configuration. In the present invention, a plurality of drainage holes for drainage during dehydration may also be formed over substantially the entire area of ​​the peripheral wall of the washing tank 12.

[0041] A stirring member 13 is disposed at the bottom of the washing tub 12. The stirring member 13 is a member for stirring the water in the washing tub 12. The stirring member 13 is rotatable relative to the washing tub 12. The rotation axis of the stirring member 13 coincides with the rotation axis of the washing tub 12. The stirring member 13 is connected to a driving mechanism 50. The driving mechanism 50 is disposed below the washing tub 12. The stirring member 13 is driven to rotate by the driving mechanism 50.

[0042] In addition, the driving mechanism 50 drives the washing tub 12 to rotate. A clutch 51 is provided between the driving mechanism 50, the washing tub 12 and the stirring member 13. Through the clutch 51, the state in which the power of the driving mechanism 50 is transmitted to the washing tub 12 and the stirring member 13 and the state in which the power of the driving mechanism 50 is transmitted only to the stirring member 13 are switched. In a state in which only the stirring member 13 and the driving mechanism 50 are connected by the clutch 51, the washing tub 12 can rotate relative to the water tank 11 and the stirring member 13 in two directions, the forward direction and the reverse direction. However, in the present invention, it is also possible that in a state in which only the stirring member and the driving mechanism are connected by the clutch, the washing tub cannot rotate relative to the water tank.

[0043] A plurality of brackets are arranged in the washing tank 12. The bracket is a component for fixing the laundry 70. In the present embodiment, the plurality of brackets are rotatably arranged on the washing tank 12. Specifically, the plurality of brackets are arranged on the stirring member 13. Therefore, the plurality of brackets rotate together with the stirring member 13.

[0044] The plurality of brackets are arranged at equal intervals around the rotation axis of the stirring element 13. The number of brackets of the stirring element 13 is not particularly limited. The stirring element 13 preferably has 2 to 10 brackets, and more preferably has 4 to 6 brackets, for example.

[0045] The stand portion can be constituted by, for example, a rod-shaped body or a plate-shaped body extending upward from the agitator 13. In this case, for example, the rod-shaped body or the plate-shaped body constituting the stand portion can be inserted into the laundry 70 such as shoes to fix the laundry 70.

[0046] In the present invention, “fixed” includes not only a meaning that the fixed object cannot be displaced at all relative to the fixed object, but also a meaning that the displacement of the fixed object relative to the fixed object is restricted.

[0047] like Figure 2 and Figure 3 As shown, a brush 6 is arranged in the washing tank 12. In this embodiment, the brush 6 is non-rotatably provided on the washing tank 12. Specifically, the brush 6 is detachably mounted on the inner peripheral surface 12a of the washing tank 12. Therefore, the bracket portion described above is rotatable relative to the brush 6.

[0048] The brush 6 is provided only on a portion of the entire circumference of the inner circumferential surface 12a of the washing tank 12. In other words, the brush 6 is not provided over the entire circumference of the inner circumferential surface 12a of the washing tank 12. In the first embodiment, only one brush 6 is provided with a central angle within a range of about 10° to 45°.

[0049] The brush 6 and the bracket part may be opposite to each other in the radial direction of the washing tank 12. When the brush 6 and the bracket part are arranged along the radial direction of the washing tank 12, the brush 6 and the bracket part are opposite to the radial direction of the washing tank 12.

[0050] Mainly as Figure 3 As shown, the brush 6 includes a fixing member 61 and at least one brush module 62. The fixing member 61 is a member for fixing at least one brush module 62 on the washing tank 12. The fixing member 61 is detachably mounted on the inner peripheral surface 12a of the washing tank 12.

[0051] like Figure 3 As shown, in this embodiment, the brush 6 has three brush modules 62, namely a first outer brush module 621, a second outer brush module 622 and an inner brush module 623. The brush modules 621, 622, 623 are respectively mounted on the fixing member 61. The brush modules 621, 622, 623 can be respectively detachably fixed on the fixing member 61, or can be non-detachably fixed on the fixing member 61.

[0052] Figure 4FIG. 1 is a schematic cross-sectional view showing a portion of the brush module 62 of the first embodiment. Figure 4 As shown, the brush module 62 has a base 63 and a plurality of bristle bundles 64. The base 63 is a component that supports the plurality of bristle bundles 64. The base 63 is plate-shaped. A plurality of holes 63a are formed on one surface of the base 63. The base ends of the bristle bundles 64 are respectively installed in the plurality of holes 63a. That is, the bristle bundles 64 are respectively planted in the plurality of holes 63a.

[0053] Although the hair bundle 64 generally has a plurality of hairs 65, it may be composed of a single hair 65. The hair 65 has an elongated shape, such as a circular, elliptical, oblong, polygonal, etc. cross-sectional shape. The hair 65 is preferably composed of an elastic body, for example. Specifically, the hair 65 can be composed of a resin such as plastic, rubber, or metal, for example.

[0054] like Figure 3 As shown, the lengths of the hairs 65 constituting the hair bundle 64 are different between the first outer brush module 621 and the second outer brush module 622 and the inner brush module 623. In the present embodiment, the hairs 65 of the inner brush module 623 are shorter than the hairs 65 of the first outer brush module 621 and the second outer brush module 622. The length of the hairs 65 of the first outer brush module 621 is substantially equal to the length of the hairs 65 of the second outer brush module 622. In addition, the length of the hairs 65 can be fixed or not fixed in each brush module 62. For example, the length of the hairs 65 can be appropriately determined according to the size or three-dimensional shape of the object 70 to be washed.

[0055] The arrangement of the plurality of bristle bundles 64 according to the present embodiment will be described in detail later.

[0056] (Overview of Operation of Washing Machine 1)

[0057] Next, the general operation of washing machine 1 will be described.

[0058] (Washing of laundry 70)

[0059] The washing of the washing object 70 such as shoes is performed in a state where detergent and water are accumulated in the washing tank 12. During the washing of the washing object 70, only the stirring member 13 of the washing tank 12 is driven to rotate by the driving mechanism 50. Thus, the brush 6 rotates relative to the washing object 70 fixed to the bracket portion provided on the stirring member 13. As a result, the brush 6 contacts the washing object 70 and washes the washing object 70. In addition, when washing the washing object 70, as long as the washing tank 12 and the bracket portion rotate relative to each other, the washing tank 12 can be set to be non-rotatable relative to the water tank 11, or it can be set to be rotatable relative to the water tank 11.

[0060] (Dehydration of laundry 70)

[0061] After washing the laundry 70, the laundry 70 can be optionally dehydrated. Specifically, after washing the laundry 70 is finished, detergent and water are discharged from the washing tank 12 via the dehydration part and the drain hole provided in the washing tank 12. Then, the stirring member 13 and the washing tank 12 are integrally driven to rotate by the driving mechanism. As a result, centrifugal force acts on the laundry 70 fixed to the bracket part provided in the stirring member 13, thereby dehydrating the laundry 70.

[0062] Furthermore, when the laundry object 70 is a shoe, for example, the shoe is preferably fixed to the bracket portion in a manner that the opening of the shoe faces radially outward. In this way, water in the shoe can be effectively discharged to the outside.

[0063] Figure 5 This is a schematic diagram for explaining the arrangement of the plurality of bristle bundles 64 according to the first embodiment. Figure 6 This is a schematic diagram for explaining the contact between the bristle bundle 64 and the laundry 70 according to the first embodiment. Figure 5 and Figure 6 This is a schematic diagram showing the hair bundle 64 as a "circle (○) (including a "circle (○) of an inscribed quadrilateral (□)" and a "circle (○) of an inscribed triangle (△)"). Figure 5 and Figure 6 The arrangement of the plurality of bristle bundles 64 according to the first embodiment will be described.

[0064] like Figure 5 As shown, in the first embodiment, the arrangement patterns of the plurality of bristle bundles 64 are different from each other in the first outer brush module 621 , the second outer brush module 622 , and the inner brush module 623 .

[0065] In the inner brush module 623 located in the center (inner side) in the rotation direction R (including the forward rotation direction R1 and the reverse rotation direction R2) of the bracket part (washing tank 12) among the three brush modules 621, 622, and 623, a plurality of bristles 64 are arranged in a matrix along the rotation direction R and the rotation axis direction A of the bracket part (washing tank 12). Specifically, the arrangement of the plurality of bristles 64 in the inner brush module 623 is a square array arrangement along the rotation direction R and the rotation axis direction A.

[0066] The number of rows and columns of the plurality of bristle bundles 64 in the inner brush module 623 is not particularly limited. For example, the number of rows of the plurality of bristle bundles 64 in the inner brush module 623 can be appropriately determined based on the size of the assumed object 70 to be washed, the diameter of the bristle bundles 64, the arrangement spacing of the bristle bundles 64, etc. For example, the number of rows of the plurality of bristle bundles 64 in the inner brush module 623 can be set to about 10 to 100. For example, the number of columns of the plurality of bristle bundles 64 in the inner brush module 623 can be appropriately determined based on the size of the assumed object 70 to be washed, the diameter of the bristle bundles 64, the arrangement spacing of the bristle bundles 64, etc. For example, the number of columns of the plurality of bristle bundles 64 in the inner brush module 623 can be set to about 3 to 100.

[0067] The multiple bristle bundles 64 are arranged in a snake shape along the rotation axis direction A in the first outer brush module 621 and the second outer brush module 622 located on the outside in the rotation direction R among the three brush modules 621, 622, and 623. Specifically, in each of the first outer brush module 621 and the second outer brush module 622, the multiple bristle bundles 64 constitute multiple (specifically two) bristle bundle columns arranged in a snake shape along the rotation axis direction A. The period of arrangement of the multiple bristle bundles 64 in the first outer brush module 621 along the rotation axis direction A and the period of arrangement of the multiple bristle bundles 64 in the second outer brush module 622 along the rotation axis direction A are offset by half a period (π). Therefore, the arrangement of the multiple bristle bundles 64 in the first outer brush module 621 and the arrangement of the multiple bristle bundles 64 in the second outer brush module 622 are in a line symmetric relationship with respect to the symmetry axis extending along the rotation axis direction A.

[0068] Among the plurality of bristle bundles 64 included in the brush 6, the one located at the most downstream side in the normal rotation direction R1 (the most upstream side in the reverse rotation direction R2) is Figure 5 and Figure 6 A bristle bundle group consisting of a plurality of bristle bundles (the bristle bundles represented by circles (○) inscribed in quadrilaterals (□)) r1 (the leftmost side in the middle) 64a is set as a first adjacent bristle bundle group 66a.

[0069] Among the plurality of bristle bundles 64 included in the brush 6, the one located at the most downstream side in the reverse direction R2 (the most upstream side in the forward direction R1, Figure 5 and Figure 6 A bristle bundle group consisting of a plurality of bristle bundles (bristle bundles represented by circles (○) inscribed in triangles (△)) r2 (the rightmost side in the middle) 64b is set as a second adjacent bristle bundle group 66b.

[0070] like Figure 6As described above, the first adjacent hair bundle group 66a and the second adjacent hair bundle group 66b are hair bundle groups 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 hair bundle groups composed of a plurality of hair bundles 64 that first come into contact with the laundry 70 that is rotating among the plurality of hair bundles 64. Specifically, the first adjacent hair bundle group 66a is a hair bundle group composed of a plurality of hair bundles 64a that are adjacent to the laundry 70 in the forward rotation direction R1 among the plurality of hair bundles 64. That is, the first adjacent hair bundle group 66a is a hair bundle group composed of a plurality of hair bundles 64a that first come into contact with the laundry 70 that is rotating from the downstream side r1 to the upstream side r2 of the forward rotation direction R1 among the plurality of hair bundles 64. The second adjacent hair bundle group 66b is a hair bundle group composed of a plurality of hair bundles 64b that are adjacent to the laundry 70 in the reverse rotation direction R2 among the plurality of hair bundles 64. That is, the second adjacent hair bundle group 66b is a hair bundle group composed of the hair bundles 64b that first contact the laundry 70 rotating from the upstream side r2 to the downstream side r1 of the reversing direction R2 among the hair bundles 64. Here, "first contact" means the first contact among the hair bundles 64 arranged along the rotating direction R.

[0071] The first adjacent hair bundle group 66a and the second adjacent hair bundle group 66b respectively include a first direction inclined relative to the rotation direction R (for example, Figure 5 and Figure 6 A plurality of hair bundles 64 are arranged in a second direction different from the first direction (for example, in the left direction) and in a second direction different from the first direction (for example, in the left direction) that is inclined relative to the rotation direction R. Figure 5 and Figure 6 Specifically, the first adjacent bristle bundle group 66a and the second adjacent bristle bundle group 66b are arranged in a snake shape along the rotation axis direction A.

[0072] However, for example, when the hair bundles included in the brush are arranged in a square array, the hair bundles constituting the adjacent hair bundle groups are arranged in a straight line along the rotation axis direction. Therefore, when the laundry rotates toward the brush, the hair bundles constituting the adjacent hair bundle groups can contact the laundry at the same time. Therefore, when the brush contacts the laundry, a large impact is exerted on the laundry. Therefore, the laundry is easily damaged.

[0073] In this regard, in this embodiment, if Figure 6As shown, the adjacent tuft groups 66a and 66b are arranged so as to include tufts 64 that contact the laundry 70 at different times when the laundry 70 fixed to the support portion rotates relative to the brush 6. Specifically, the first adjacent tuft group 66a is arranged so as to include tufts 64 that contact the laundry 70a that rotates in the forward direction R1 from the upstream side r1 to the downstream side r2 and rotates relative to the brush 6 at different times. The second adjacent tuft group 66b is arranged so as to include tufts 64 that contact the laundry 70b that rotates in the reverse direction R2 from the upstream side r2 to the downstream side r1 and rotates relative to the brush 6. Therefore, it is possible to suppress the plural tufts 64 constituting the adjacent tuft groups 66a and 66b from contacting the laundry 70 at the same time. Therefore, it is possible to reduce the impact applied to the laundry 70 when the brush 6 contacts the laundry 70. Therefore, damage to the laundry 70 can be suppressed.

[0074] From the perspective of suppressing damage to the laundry 70, it is considered that it is preferred that the adjacent hair bundle groups 66a and 66b do not include hair bundles 64 that contact the laundry 70 that rotates relatively at the same time, so that all the multiple hair bundles 64 that constitute the adjacent hair bundle groups 66a and 66b contact the laundry 70 at different times. Specifically, for example, it is preferred to arrange the adjacent hair bundle groups 66a and 66b in a spiral shape. However, in this case, the central angle of the area where the brush is set becomes larger. Therefore, the configuration space of the laundry is limited. Therefore, the number of laundry that can be set is reduced.

[0075] In this regard, in the present embodiment, adjacent tuft groups 66a, 66b are arranged so as to respectively include tufts 64 that contact the laundry 70 at the same time when the laundry 70 fixed to the support portion rotates relative to the brush 6. Therefore, the arrangement space of the brush 6 (the central angle range where the brush 6 is located) can be reduced. Therefore, the number of laundry 70 that can be set at one time can be increased. As described above, according to the washing machine 1 involved in the present embodiment, a plurality of laundry 70 can be cleaned at one time, and damage to the laundry 70 during washing can be suppressed.

[0076] The number of washable items 70 that can be selected at one time is further increased, and from the viewpoint of more effectively suppressing damage to the washable items 70 during washing, it is preferred that the first adjacent tuft group 66a located on the upstream side r1 of the forward rotation direction R1 and the second adjacent tuft group 66b located on the upstream side r2 of the reverse rotation direction R2 respectively include tufts 64 that contact the washable items 70 that are relatively rotated at different times and tufts 64 that contact the washable items 70 that are relatively rotated at the same time. It is more preferred that the adjacent tuft groups 66a and 66b respectively include a plurality of tufts 64 arranged in the first direction and a plurality of tufts 64 arranged in the second direction. It is further preferred that the adjacent tuft groups 66a and 66b are arranged in a snake shape along the rotation axis direction A. In this case, damage to the washable items 70 can be suppressed in both cases when the washable items 70 rotate in the forward rotation direction R1 and when the washable items rotate in the reverse rotation direction R2.

[0077] In addition, in the present embodiment, when the hair bundles 64 come into contact with the laundry 70, there are many hair bundles 64 that are not adjacent to the hair bundles 64 on either one side or the other side of the rotation axis direction A, on the opposite side of the hair bundles 64 from the laundry 70 in the rotation direction R. Since it is difficult to restrict the deformation of the adjacent hair bundles 64, these hair bundles 64 are easily deformed. Therefore, it is possible to suppress the laundry 70 from being damaged by the contact with the hair bundles 64. From the viewpoint of increasing the ratio of the hair bundles 64 that are difficult to restrict the deformation, it is preferable to arrange the hair bundle row composed of a plurality of hair bundles 64 arranged continuously in a snake shape.

[0078] In the following description, components having substantially the same functions as those of the first embodiment are denoted by common reference numerals, and description thereof is omitted.

[0079] (Second embodiment)

[0080] Figure 7 Schematic diagram for explaining the arrangement of the bristles of the second embodiment. The washing machine of the second embodiment differs from the washing machine of the first embodiment in the arrangement pattern of the bristles 64 of the brush 6, and the other structures are the same. Specifically, in the second embodiment, only the arrangement pattern of the bristles 64 in the outer brush modules 621 and 622 is different from that in the first embodiment. Figure 7 Next, the arrangement pattern of the plurality of bristle bundles 64 in the outer brush modules 621 and 622 in the second embodiment will be described.

[0081] In a first embodiment, if Figure 5 As shown, the example in which a plurality of bristle bundles 64 (specifically two bristle bundles 64) in the outer brush modules 621 and 622 are arranged adjacent to each other along the rotation direction R is described. Figure 7 As shown, in the second embodiment, there are no adjacent hair bundles 64 in the outer brush modules 621 and 622 in the rotation direction R. In other words, in the second embodiment, all the hair bundles 64 of the outer brush modules 621 and 622 are located at different positions in the rotation axis direction A. In each outer brush module 621 and 622, the adjacent direction of two adjacent hair bundles 64 is the rotation axis direction A or a direction inclined relative to the rotation direction R. Therefore, all the multiple hair bundles 64 of the outer brush modules 621 and 622 are arranged in such a way that when the hair bundles 64 and the laundry 70 are in contact, the hair bundles 64 in the rotation direction R are not adjacent to the hair bundles 64 on the opposite side of the laundry 70. Therefore, it is difficult to limit the deformation of the hair bundles 64 when the hair bundles 64 contact the laundry 70. Therefore, it is possible to more effectively suppress the laundry 70 from being damaged due to the contact with the hair bundles 64.

[0082] However, since the more bristles 64 contacting each position of the laundry 70, the higher the cleaning power, the arrangement of the bristles 64 in the first embodiment is more preferable than the arrangement of the bristles 64 in the second embodiment from the viewpoint of improving the cleaning power of the washing machine.

[0083] In a first embodiment, if Figure 5 As shown, the description is given for an example in which the hair bundle rows composed of a plurality of hair bundles arranged continuously in the outer brush modules 621 and 622 are arranged in a snake shape with a period greater than 1. In this regard, in the second embodiment, as Figure 7 As shown, in the outer brush modules 621 and 622, the hair bundles are arranged in a serpentine shape with a period less than 1 (specifically, a 1 / 2 period). Even in the case where the hair bundles are arranged in a serpentine shape with a period less than 1 as in the second embodiment, as long as the adjacent hair bundle groups 66a and 66b are arranged so as to include hair bundles 64 that contact the rotating laundry 70 at different times, the impact applied to the laundry 70 when the hair bundles 64 contact the laundry 70 can be reduced. Therefore, damage to the laundry 70 can be suppressed.

[0084] (Third Embodiment)

[0085] Figure 8 64 of the third embodiment. The third embodiment differs from the first and second embodiments only in the arrangement pattern of the plurality of bristle bundles 64 of the outer brush modules 621 and 622. Figure 8 Next, the arrangement pattern of the plurality of bristle bundles 64 of the outer brush modules 621 and 622 according to the third embodiment will be described.

[0086] like Figure 5 and Figure 7As shown, in the first and second embodiments, the description is made of an example in which a plurality of bristle bundles 64 constitute one bristle bundle in each outer brush module 621, 622, and the one bristle bundle row is constituted by a plurality of bristle bundles 64 arranged continuously in parallel. However, the present invention is not limited to this configuration.

[0087] like Figure 8 As shown, in the third embodiment, in the first outer brush module 621, a plurality of hair bundles 64 constitute a plurality of hair bundle columns 67a, 67b including a portion of hair bundles 64 in common with each other. The hair bundle columns 67a and 67b have a mutually intersecting intersection. In the second outer brush module 622, a plurality of hair bundles 64 constitute a plurality of hair bundle columns 67c, 67d including a portion of hair bundles 64 in common with each other. The hair bundle columns 67c and 67d have a mutually intersecting intersection. Even in the third embodiment, as long as the adjacent hair bundle groups 66a, 66b are arranged in a manner including hair bundles 64 that contact the rotating laundry 70 at different times, the impact applied to the laundry 70 can be reduced when the hair bundles 64 and the laundry 70 contact. Therefore, damage to the laundry 70 can be suppressed.

[0088] In the third embodiment, the plurality of bristles 64 of each bristle column 67a, 67b, 67c, 67d are arranged so as to be located at different positions in the rotation axis direction A. And the bristle columns 67a, 67b, 67c, 67d are respectively composed of only the parts of the plurality of bristle bundles 64 arranged in a direction inclined with respect to the rotation axis direction A. Therefore, in the outer brush modules 621, 622, there are no adjacent bristle bundles 64 in the rotation direction R. In other words, the positions of all the bristle bundles 64 in the outer brush modules 621, 622 in the rotation axis direction A are different. In each outer brush module 621, 622, the direction in which two adjacent bristle bundles 64 are adjacent is a direction inclined with respect to the rotation axis direction A. Therefore, all the plurality of bristle bundles 64 of the outer brush modules 621, 622 are arranged so that when the bristle bundles 64 and the laundry 70 are in contact, the bristle bundles 64 in the rotation direction R are not adjacent to the bristle bundles 64 on the opposite side of the laundry 70. Therefore, it is difficult to restrict the deformation of the bristle bundle 64 when the bristle bundle 64 contacts the laundry 70. Therefore, it is possible to more effectively suppress the laundry 70 from being damaged due to the contact with the bristle bundle 64.

[0089] (Fourth Embodiment)

[0090] Fig. 9 Schematic diagram for explaining the arrangement of the bristle bundles 64 of the fourth embodiment. The fourth embodiment differs from the first embodiment and the like only in the arrangement pattern of the plurality of bristle bundles 64 in the outer brush modules 621 and 622. Fig. 9 Next, the arrangement pattern of the plurality of bristle bundles 64 of the outer brush modules 621 and 622 according to the fourth embodiment will be described.

[0091] like Figure 5 and Figure 7 As shown, in the first and second embodiments, the description is made of an example in which a plurality of bristle bundles 64 constitute one bristle bundle row in each outer brush module 621, 622, and the one bristle bundle row is constituted by a plurality of bristle bundles 64 arranged continuously in parallel. However, the present invention is not limited to this configuration.

[0092] like Fig. 9 As shown, in the fourth embodiment, a plurality of bristles 64 are fixed in the first outer brush module 621 to form a plurality of bristle bundle columns 67e. The plurality of bristle bundle columns 67e are arranged along the rotation axis direction A. The plurality of bristle bundle columns 67e are respectively composed of a plurality of bristle bundles 64, and the plurality of bristle bundles 64 are respectively arranged in a continuous direction inclined relative to the rotation direction R and the rotation axis direction A. In the second outer brush module 622, a plurality of bristle bundles 64 constitute a plurality of bristle bundle columns 67f. The plurality of bristle bundle columns 67f are arranged along the rotation axis direction A. The plurality of bristle bundle columns 67f are respectively composed of a plurality of bristle bundles 64, and the plurality of bristle bundles 64 are respectively arranged in a continuous direction inclined relative to the rotation direction R and the rotation axis direction A.

[0093] Even when the plurality of bristles 64 in the outer brush modules 621 and 622 form a plurality of bristle bundle rows 67e and 67f arranged side by side, as long as the adjacent bristle bundle groups 66a and 66b are arranged so as to include bristle bundles 64 that contact the rotating laundry 70 at different times, the impact applied to the laundry 70 when the bristle bundles 64 contact the laundry 70 can be reduced. Therefore, damage to the laundry 70 can be suppressed.

[0094] In the fourth embodiment, the multiple hair bundle columns 67e are separated. In addition, the multiple hair bundle columns 67f are separated. Therefore, in the outer brush modules 621 and 622, there are no adjacent hair bundles 64 in the rotation direction R. In other words, the positions of all the hair bundles 64 of the outer brush modules 621 and 622 in the rotation axis direction A are different. In each outer brush module 621 and 622, the adjacent direction of two adjacent hair bundles 64 is a direction inclined relative to the rotation axis direction A. Therefore, all the multiple hair bundles 64 of the outer brush modules 621 and 622 are arranged in a manner that when the hair bundles 64 and the laundry 70 are in contact, there are no hair bundles 64 adjacent to the laundry 70 on the opposite side of the laundry 70. Therefore, it is difficult to limit the deformation of the hair bundles 64 when the hair bundles 64 contact the laundry 70. Therefore, it is possible to more effectively suppress the laundry 70 from being damaged by the contact with the hair bundles 64.

[0095] (Fifth Embodiment)

[0096] Fig.1064 of the fifth embodiment. The fifth embodiment differs from the first embodiment and the like only in the arrangement pattern of the plurality of bristle bundles 64 in the outer brush modules 621 and 622. Fig.10 Next, the arrangement pattern of the plurality of bristle bundles 64 of the outer brush modules 621 and 622 according to the fifth embodiment will be described.

[0097] like Fig.10 As shown, in the fifth embodiment, the plurality of bristles 64 in each outer brush module 621, 622 constitute a continuously arranged bristle column. The bristle column includes a portion where the plurality of bristles 64 are arranged along the rotation direction R. Even in this case, as long as the adjacent bristle groups 66a, 66b are arranged in a manner that includes bristles 64 that contact the rotating laundry 70 at different times, the impact applied to the laundry 70 when the bristle bundles 64 contact the laundry 70 can be reduced. Therefore, damage to the laundry 70 can be suppressed.

[0098] Even in the fifth embodiment, in each outer brush module 621, 622, a part of the plurality of bristle bundles 64 does not have adjacent bristle bundles 64 in the rotation direction R. As a result, it is difficult to restrict the deformation of the bristle bundles 64 when the bristle bundles 64 contact the laundry 70. Therefore, it is possible to more effectively suppress the laundry 70 from being damaged by contact with the bristle bundles 64.

[0099] (Sixth Embodiment)

[0100] Fig.11 Schematic diagram for explaining the arrangement of the hair bundles 64 of the sixth embodiment. Figure 5 As shown, in the first embodiment, the brush 6 is described as including the inner brush module 623 in addition to the first outer brush module 621 and the second outer brush module 622. However, the present invention is not limited to this configuration.

[0101] In the sixth embodiment, the brush 6 is composed of the first outer brush module 621 and the second outer brush module 622, and does not include the inner brush module 623. Even in the sixth embodiment, since the adjacent hair bundle groups 66a and 66b are arranged in a manner that includes hair bundles 64 that contact the rotating laundry 70 at different times, the impact applied to the laundry 70 can be reduced when the hair bundles 64 contact the laundry 70. Therefore, damage to the laundry 70 can be suppressed.

[0102] In the sixth embodiment, the plurality of hair bundles 64 are arranged in a square array, and the inner brush module 623 for limiting the deformation of the hair bundles 64 is not provided. As a result, it is difficult to limit the deformation of the hair bundles 64 when the hair bundles 64 contact the laundry 70. Therefore, it is possible to more effectively prevent the laundry 70 from being damaged by contact with the hair bundles 64.

[0103] (Seventh Embodiment)

[0104] Fig.12 Schematic diagram for explaining the arrangement of the hair bundles 64 of the seventh embodiment. Fig.11 As shown, in the sixth embodiment, the hair bundle row composed of the plurality of hair bundles 64 of the first outer brush module 621 and the hair bundle row composed of the plurality of hair bundles 64 of the second outer brush module 622 are described as being offset by half a period (π) in the rotation axis direction A. However, the present invention is not limited to this configuration.

[0105] like Fig.12 As shown, in the seventh embodiment, the period of the hair bundle column composed of the plurality of hair bundles 64 of the first outer brush module 621 in the rotation axis direction A is the same as the period of the hair bundle column composed of the plurality of hair bundles 64 of the second outer brush module 622 in the rotation axis direction A. Even in the seventh embodiment, since the adjacent hair bundle groups 66a and 66b are arranged in a manner including the hair bundles 64 that contact the rotating laundry 70 at different times, the impact applied to the laundry 70 can be reduced when the hair bundles 64 contact the laundry 70. Therefore, damage to the laundry 70 can be suppressed.

[0106] (Eighth Implementation Method)

[0107] Fig.13 Schematic diagram for explaining the arrangement of the hair bundles 64 of the eighth embodiment. The eighth embodiment differs from the seventh embodiment in that the first outer brush module 621 and the second outer brush module 622 are designed as one body. As in the eighth embodiment, the plurality of hair bundles 64 included in the brush 6 may belong to one brush module or to a plurality of brush modules.

[0108] (Ninth embodiment)

[0109] Fig.14 Schematic diagram for explaining the arrangement of the hair bundles 64 of the ninth embodiment. Fig.13 As shown, in the eighth embodiment, the phase of the first outer brush module 621 in the rotation axis direction A is consistent with the phase of the second outer brush module 622 in the rotation axis direction A. Fig.14As shown, in the ninth embodiment, the phase of the first outer brush module 621 in the rotation axis direction A is offset from the phase of the second outer brush module 622 in the rotation axis direction A. Specifically, in the ninth embodiment, the phase of the first outer brush module 621 in the rotation axis direction A is offset from the phase of the second outer brush module 622 in the rotation axis direction A within a period range less than 1 / 4. Even in this case, since the adjacent tuft groups 66a, 66b are arranged in a manner that includes tufts 64 that contact the rotating laundry 70 at different times, the impact applied to the laundry 70 can be reduced when the tufts 64 and the laundry 70 contact. Therefore, damage to the laundry 70 can be suppressed.

[0110] (Tenth embodiment)

[0111] Fig.15 This is a schematic diagram for explaining the arrangement of bristle bundles according to the tenth embodiment. Fig.15 The "circle of the inscribed triangle (△) and quadrilateral (□)" is the "circle of the inscribed triangle (△)" and the "circle of the inscribed quadrilateral (□)". Fig.16 and Fig.17 Same.

[0112] like Fig.15 As shown, in the tenth embodiment, a plurality of hair bundles 64 constitute a plurality of hair bundle columns 68 arranged along the rotation axis direction A. The plurality of hair bundle columns 68 each include a plurality of hair bundles arranged continuously and side by side. The plurality of hair bundle columns 68 are arranged in a snake shape along the rotation direction R. The plurality of hair bundle columns 68 are arranged in a manner that all have the same period in the rotation direction R. Even in this case, since the adjacent hair bundle groups 66a, 66b are arranged in a manner that includes hair bundles 64 that contact the rotating laundry 70 at different times, the impact applied to the laundry 70 can be reduced when the hair bundles 64 and the laundry 70 contact. Therefore, damage to the laundry 70 can be suppressed.

[0113] In the tenth embodiment, there are no adjacent bristle bundles 64 in the rotation direction R. This makes it difficult to restrict the deformation of the bristle bundles 64 when the bristle bundles 64 contact the laundry 70. Therefore, it is possible to more effectively prevent the laundry 70 from being damaged by contact with the bristle bundles 64.

[0114] (Eleventh Embodiment)

[0115] Fig.16 Schematic diagram for explaining the arrangement of the hair bundles 64 of the eleventh embodiment. Fig.15 As shown, in the tenth embodiment, the description is given of an example in which the plurality of bristle bundle rows 68 are all arranged in accordance with the period in the rotation direction R. However, the present invention is not limited to this.

[0116] like Fig.16 As shown in the figure, in the eleventh embodiment, the periods in the rotation direction R are different between two adjacent hair bundle rows 68 in the rotation axis direction A. The period of the hair bundle row 68 in the rotation direction R gradually changes toward one side of the rotation axis direction A. Even in this case, since the adjacent hair bundle groups 66a and 66b are arranged so as to include hair bundles 64 that contact the rotating laundry 70 at different times, the impact applied to the laundry 70 when the hair bundles 64 contact the laundry 70 can be reduced. Therefore, damage to the laundry 70 can be suppressed.

[0117] In the eleventh embodiment, similarly to the tenth embodiment, there are no bristle bundles 64 adjacent to each other in the rotation direction R among all the plurality of bristle bundles 64. Thus, it is difficult to restrict the deformation of the bristle bundles 64 when the bristle bundles 64 contact the laundry 70. Therefore, it is possible to more effectively suppress the laundry 70 from being damaged by the contact with the bristle bundles 64.

[0118] (Twelfth Implementation Method)

[0119] Fig.17 Schematic diagram for explaining the arrangement of hair bundles in the twelfth embodiment. Fig.17 As shown, in the twelfth embodiment, a plurality of hair bundles 64 constitute a plurality of hair bundle rows 69a and 69b. The hair bundle rows 69a and 69b are respectively constituted by a plurality of hair bundles 64 arranged in a continuous and parallel manner. The arrangement shape of the hair bundle row 69a is similar to the arrangement shape of the hair bundle row 69b. The arrangement shape of the hair bundle row 69b is consistent with the shape obtained by rotating the arrangement shape of the hair bundle row 69a by 180 degrees around a rotation axis perpendicular to both the rotation direction R and the rotation axis direction A. The hair bundle rows 69a and 69b respectively have a portion opposite to the rotation direction R and a portion opposite to the rotation axis direction A.

[0120] Even in the twelfth embodiment, since the adjacent tuft groups 66a and 66b are arranged so as to include tufts 64 that contact the rotating laundry 70 at different times, the impact applied to the laundry 70 can be reduced when the tufts 64 contact the laundry 70. Therefore, damage to the laundry 70 can be suppressed.

[0121] (Thirteenth embodiment)

[0122] Fig.18 Schematic diagram for explaining the arrangement of the hair bundles 64 of the thirteenth embodiment. Fig.18 As shown, in the thirteenth embodiment, the plurality of bristle bundles 64 form a bristle bundle row in which the number of bristle bundles 64 arranged along the rotation direction R is changed along the rotation axis direction A.

[0123] Even in the thirteenth embodiment, since the adjacent tuft groups 66a and 66b are arranged so as to include tufts 64 that contact the rotating laundry 70 at different times, the impact applied to the laundry 70 can be reduced when the tufts 64 and the laundry 70 contact. Therefore, damage to the laundry 70 can be suppressed.

[0124] In the thirteenth embodiment, the bristle bundles 64 are arranged between the adjacent bristle bundle groups 66a and the adjacent bristle bundle groups 66b. Therefore, the number of bristle bundles 64 can be increased compared to the case where at least one bristle bundle 64 is not arranged at equal intervals between the adjacent bristle bundle groups 66a and the adjacent bristle bundle groups 66b along the rotation direction R. Therefore, the cleaning power can be improved.

[0125] (Fourteenth embodiment)

[0126] Fig.19 14 is a schematic diagram for explaining the arrangement of the hair bundles 64 of the fourteenth embodiment. Fig.19 As shown, in the fourteenth embodiment, the adjacent hair bundle groups 66a and 66b each have a first portion extending toward one side of the rotation direction R and a second portion extending toward the other side, which is inclined relative to the rotation axis direction A. The number of hair bundles 64 arranged in the first portion is different from the number of hair bundles 64 arranged in the second portion. The length of the first portion is different from the length of the second portion. The adjacent hair bundle groups 66a and 66b each have a serpentine shape along a direction inclined relative to the rotation axis direction A.

[0127] Even in the fourteenth embodiment, since the adjacent tuft groups 66a and 66b are arranged so as to include tufts 64 that contact the rotating laundry 70 at different times, the impact applied to the laundry 70 can be reduced when the tufts 64 and the laundry 70 contact. Therefore, damage to the laundry 70 can be suppressed.

[0128] In the fourteenth embodiment, all the plurality of bristle bundles 64 do not exist in the bristle bundles 64 adjacent to each other in the rotation direction R. This makes it difficult to restrict the deformation of the bristle bundles 64 when the bristle bundles 64 contact the laundry 70. Therefore, it is possible to more effectively suppress the laundry 70 from being damaged by the contact with the bristle bundles 64.

[0129] (Fifteenth embodiment)

[0130] Fig. 20 Schematic diagram for explaining the arrangement of hair bundles according to the fifteenth embodiment. Fig. 20 As shown, in the fifteenth embodiment, adjacent hair bundle groups 66a and 66b are alternately provided with first portions extending toward one side of the rotation direction R and second portions extending toward the other side, which are inclined relative to the rotation axis direction A. The lengths of the first portions and the second portions are random.

[0131] Even in the fifteenth embodiment, since the adjacent tuft groups 66a and 66b are arranged so as to include tufts 64 that contact the rotating laundry 70 at different times, the impact applied to the laundry 70 can be reduced when the tufts 64 contact the laundry 70. Therefore, damage to the laundry 70 can be suppressed.

[0132] In the fifteenth embodiment, all of the plurality of bristle bundles 64 do not exist in the bristle bundles 64 adjacent to each other in the rotation direction R. This makes it difficult to restrict the deformation of the bristle bundles 64 when the bristle bundles 64 contact the laundry 70. Therefore, damage to the laundry 70 caused by contact with the bristle bundles 64 can be more effectively suppressed.

[0133] (Variation)

[0134] In the above embodiment, the case where only one brush 6 is provided is described. However, the present invention is not limited to this configuration.
