[0026] As shown in Figures 5 and 6, the core material 18 has a core plate 20 and a plurality (for example, three) of protrusions 21. The core plate 20 is formed in a rectangular plate shape and has a plate surface 20A and a plate surface 20B in the core plate thickness direction. Each protrusion 21 is arranged at intervals between them in the core plate length direction of the core plate 20. Each protrusion 21 protrudes from the plate surface 20A of the core plate 20 in the core plate thickness direction of the core plate 20 and is fixed to the core plate 20.

[0027] The dust-collecting brush material 19 (first dust-collecting brush material) has a base fabric 25 and a dust-collecting brush 26 (brush), as shown in Figures 3 to 6. The dust-collecting brush 26 is formed of a plurality of inclined piles δ (inclined cut piles) that are inclined in one direction with respect to the fabric surface 25A of the base fabric 25. Each inclined pile δ is woven into the base fabric 25 and positioned to protrude from the fabric surface 25A of the base fabric 25. The inclined piles δ are arranged over the entire base fabric 25 (the entire surface 25A of the base fabric 25) and positioned to protrude from the fabric surface 25A of the base fabric 25. The inclined piles δ are composed of a plurality of first fibers and a plurality of second fibers bundled together (twisted), and consist of synthetic fibers including polyamide fibers, polyester fibers, polypropylene fibers, and acrylic fibers, and regenerated fibers including rayon fibers. The first fibers constituting the inclined piles δ are the first inclined brush bristles F1. The second fiber constituting the inclined pile δ is the second inclined brush bristle F2.

[0028] Each first inclined brush bristle F1 is formed to the same thickness. The thickness of each first inclined brush bristle F1 is a diameter of 0.0300 mm to 0.0900 mm, for example, a diameter of 0.0418 mm (15.7 decitex). Each second inclined brush bristle F2 is formed to the same thickness but different from the thickness of the first inclined brush bristle F1. The thickness of each second inclined brush bristle F2 is formed to be thicker than the first inclined brush bristle F1, for example, a diameter of 0.115 mm (120 decitex).

[0029] Each first inclined brush bristle F1 is formed to the same length. The length of each first inclined brush bristle F1 is between 1.00 mm and 3.00 mm, for example, 1.80 mm. The length of each first inclined brush bristle F1 is, for example, the sum of the thickness of the base fabric 25 and the protruding length of the first inclined brush bristle F1 protruding from the fabric surface 25A of the base fabric 25. Each second inclined brush bristle F2 is formed to the same length, but longer than the length of the first inclined brush bristle F1.

The pressing projection 64 is positioned between the guide projection 62 and the other inner circumferential surface 51d in the case width direction W1 of the case body 51, with a gap between them and the other inner circumferential surface 51d in the case width direction W1.

[0058] As shown in Figures 9 and 12, the bottom portion 52 (bottom plate) closes the other end 51B of the case body 51 and is fixed to the case body 51.

[0059] Each dust removal brush body 53 to 55 is arranged inside the case body 51, as shown in Figures 12 to 15. Each dust removal brush body 53 to 55 is fixed to the inner circumferential surface of the case body 51. Each dust removal brush body 53 to 55 is fixed, for example, to one inner circumferential surface 51a of the case body 51 in the case thickness direction T1. Each dust removal brush body 53 to 55 is positioned on one end 51A side of the case body 51 in the direction M of the cylindrical centerline m of the case body 51.

[0060] As shown in Figure 15, the first dust removal brush body 53 is positioned between one inner circumferential surface 51c and the first guide projection 61 in the case width direction W1 of the case body 51. The first dust removal brush body 53 is fixed to one inner circumferential surface 51a in the plate thickness direction T1 of the case body 51.

[0062] As shown in Figure 15, the third dust removal brush body 55 is positioned between the guide protrusions 61 and 62 in the case width direction W1 of the case body 51. The third dust removal brush body 55 is fixed to one inner circumferential surface 51a in the plate thickness direction T1 of the case body 51. The third dust removal brush body 55 has a brush width in the case width direction W1 of the case body 51 and a brush length in the direction M of the cylindrical centerline m of the case body 51, and is positioned on one end 51A side of the case body 51.

[0063] Each dust removal brush body 53 to 55 has a plurality of inclined brush bristles H, as shown in Figures 12 to 15. Each inclined brush bristle H is arranged across the entire width and length of each dust removal brush body 53 to 55. Each inclined brush bristle H (dust removal bristles) protrudes into the case body 51. Each inclined brush bristle H is formed to be the same thickness. Each inclined brush bristles H is formed to be the same length.

[0064] Each inclined brush bristle H of each dust removal brush body 53 to 55 is inclined toward the bottom 52 of the case body 51 with respect to one inner circumferential surface 51a (first inner circumferential surface) in the case thickness direction T1, as shown in Figures 12 to 15. Each inclined brush bristle H is inclined toward the bottom 52 (other end 51B) of the case body 51, toward one inner circumferential surface 51a (first inner circumferential surface) in the case thickness direction T1, in the direction M of the cylindrical centerline m of the case body 51.

[0065] Each dust-removing brush body 53 to 55 is composed of, for example, a dust-removing brush material 71, as shown in Figures 12 to 15. The dust-removing brush material 71 has a base fabric 72 and a dust-removing brush 73. The dust-removing brush 73 is formed of a plurality of inclined piles φ (inclined cut piles) that are inclined in one direction on the base fabric 72. Each inclined pile φ is woven into the base fabric 72 and is positioned to protrude from the fabric surface 72A of the base fabric 72. The inclined piles φ are arranged over the entire base fabric 72 (the entire surface 72A of the base fabric 72) and protrude from the fabric surface 72A of the base fabric 72. The inclined piles φ are composed of a plurality of fibers bundled (twisted) together, and are made of, for example, synthetic fibers including polyamide fibers, polyester fibers, polypropylene fibers, acrylic fibers, and regenerated fibers including rayon fibers. The fibers that make up the inclined piles φ are inclined brush bristles H.

[0066] As shown in Figures 12 and 15, the dust-removing brush material 71 of the first dust-removing brush body 53 is positioned on one end 51A of the case body 51. The dust-removing brush material 71 of the first dust-removing brush body 53 is positioned between one inner circumferential surface 51c in the case width direction W1 and the guide projection 61, with the tips of each inclined brush bristle H of each inclined pile φ facing the bottom 52 of the case body 51. The dust-removing brush material 71 of the first dust-removing brush body 53 is fixed to the inner circumferential surface 51a of the case body 51 by attaching the back surface 72B of the base fabric 72 to one inner circumferential surface 51a in the plate thickness direction T1.

[0067] As shown in Figures 13 and 15, the dust-removing brush material 71 of the second dust-removing brush body 54 is positioned on one end 51A of the case body 51. The dust-removing brush material 71 of the second dust-removing brush body 54 is positioned between the other inner circumferential surface 51d in the case width direction W1 and the guide projection 62, with the tips of each inclined brush bristle H of each inclined pile φ facing the bottom 52 of the case body 51. The dust-removing brush material 71 of the second dust-removing brush body 54 is fixed to the inner circumferential surface 51a of the case body 51 by attaching the back surface 72B of the base fabric 72 to one inner circumferential surface 51a in the plate thickness direction T1.

[0068] As shown in Figures 14 and 15, the dust-removing brush material 71 of the third dust-removing brush body 55 is positioned on one end 51A of the case body 51. The dust-removing brush material 71 of the third dust-removing brush body 55 is positioned between the guide protrusions 61, 62, with the tips of each inclined brush bristle H of each inclined pile φ facing the bottom 52 of the case body 51. The dust-removing brush material 71 of the third dust-removing brush body 55 is fixed to the inner surface 51a of the case body 51 by attaching the back surface 72B of the base fabric 72 to one inner surface 51a in the thickness direction T1. Each inclined brush bristle H of the dust-removing brush material 71 is inclined toward the direction M of the cylindrical centerline m of the case body 51 with respect to one inner surface 51a in the thickness direction T1 of the case.

[0069] As shown in Figure 1, the cleaning tool Y is positioned on the cleaning surface FL by gripping the handle 3 and pressing the inclined brush bristles F1 and F2 of the first and second dust-collecting brush bodies 7 and 8, and the upright brush bristles G of the third dust-collecting brush body 9 against the cleaning surface FL. The first and second dust-collecting brush bodies 7 and 8 are positioned by pressing the inclined brush bristles F1 and F2, which are located opposite the back surface 20B of the core plate 20, against the cleaning surface FL. The cleaning surface FL is, for example, a floor, hardwood flooring, or tatami mat.

[0070] As shown in Figure 1, the cleaning tool Y is used by gripping the handle 3 and pushing and pulling the cleaning head 1 along the surface FL to be cleaned in the width direction W, thereby pressing the inclined brush bristles F1 and F2 of the first and second dust-collecting brush bodies 7 and 8 and the upright brush bristles G of the third dust-collecting brush body 9 against the surface FL to be cleaned, thereby capturing dust and debris from the surface FL with the inclined brush bristles F1 and F2 and the upright brush bristles G. In the first and second dust-collecting brush bodies 7 and 8, the second inclined brush bristles F2, which are thicker than the first inclined brush bristles F1, primarily scrape dust and debris from the surface FL to be cleaned.

[0071] As shown in Figure 7, when the cleaning head 1 is tilted relative to the surface to be cleaned FL by pushing it, for example, the inclined brush bristles F1, F2 of the second dust collection brush body 8 and the upright brush bristles G of the third dust collection brush body 9 are pressed against the surface to be cleaned FL, and the inclined brush bristles F1, F2 of the first dust collection brush body 7 are moved away from the surface to be cleaned FL, allowing dust from the surface to be cleaned FL to enter the space ε between the first dust collection brush body 7 and the surface to be cleaned FL, thereby capturing dust from the surface to be cleaned FL with the inclined brush bristles F1, F2 of the second dust collection brush body 8 and the upright brush bristles G of the third dust collection brush body 9.

[0072] As shown in Figure 8, when the cleaning head 1 is pulled and tilted toward the surface to be cleaned FL, for example, the inclined brush bristles F1, F2 of the first dust collection brush body 7 and the upright brush bristles G of the third dust collection brush body 9 are pressed against the surface to be cleaned FL, and the inclined brush bristles F1, F2 of the second dust collection brush body 8 are moved away from the surface to be cleaned FL, allowing dust from the surface to be cleaned FL to enter the space λ between the second dust collection brush body 8 and the surface to be cleaned FL, thereby capturing dust from the surface to be cleaned FL with the inclined brush bristles F1, F2 of the first dust collection brush body 7 and the upright brush bristles G of the third dust collection brush body 9. As a result, the cleaning tool Y is tilted so that the tips of the inclined brush bristles F1 and F2 of the first and second dust-collecting brush bodies 7 and 8 face the third dust-collecting brush body 9 (each with upright brush bristles G), pressing the inclined brush bristles F1 and F2 of the first and second dust-collecting brush bodies 7 and 8 against the surface FL to be cleaned, and pressing the upright brush bristles G of the third dust-collecting brush body 9 against the surface FL to be cleaned, and by moving the cleaning head 1 in the width direction W of the plate, dust can be easily drawn into the inside of the first and second dust-collecting brush bodies 7 and 8, and the dust that has entered the inside of the first and second dust-collecting brush bodies 7 and 8 cannot be prevented from coming out to the outside of the first and second dust-collecting brush bodies 7 and 8, and dust can be reliably collected from the surface FL to be cleaned by the inclined brush bristles F1 and F2 of the first and second dust-collecting brush bodies 7 and 8 and the upright brush bristles G of the third dust-collecting brush body 9. In the cleaning tool Y, the tips of each upright brush bristles G of the third dust-collecting brush body 9 protrude from the first and second dust-collecting brush bodies 7 and 8, so that even when the cleaning head 1 is tilted relative to the surface to be cleaned FL, dust can be captured by the tilted brush bristles F1 and F2 and the upright brush bristles G of the surface to be cleaned FL.

[0073] Furthermore, in the cleaning device Y, as shown in Figures 2 and 3, a gap is placed between the first and second dust-collecting brush bodies 7 and 8 and the third dust-collecting brush body 9, with the third dust-collecting brush body 9 positioned between the first and second dust-collecting brush bodies 7 and 8. This prevents dust from accumulating between the first and second dust-collecting brush bodies 7 and 8 and the third dust-collecting brush body 9, allowing the inclined brush bristles F1 and F2 and the upright brush bristles G to capture dust from the surface FL to be cleaned. Moreover, in the cleaning device Y, the first and second dust-collecting brush bodies 7 and 8 can be removed from the cleaning body 6, and new, different first and second dust-collecting brush bodies 7 and 8 can be attached to the cleaning body 6.

[0074] As shown in Figures 9 to 15, the cleaning tool Y captures dust from the surface FL to be cleaned using the inclined brush bristles F1 and F2 of the first and second dust-collecting brush bodies 7 and 8, and the upright brush bristles G of the third dust-collecting brush body 9. The cleaning head 1 is then stored in the dust removal case Z, and the dust captured by the dust-collecting brush bodies 7 to 9 is removed by the dust-removing brush bodies 53 to 55.

[0075] As shown in Figures 9 to 14, the cleaning tool Y is positioned by rotating the handle 3 about the axis centerline γ, for example, on the surface 10A side of one end of the cleaning plate 10. The cleaning tool Y is positioned by inserting the cleaning head 1 into the case body 51 from the opening P on one end 51A of the case body 51. The cleaning tool Y is positioned by inserting the cleaning head 1 into the case body 51 from the other end of the cleaning body 6.

[0076] As shown in Figures 9 to 14, the cleaning head 1 is housed inside the case body 51 so as to be movable in the direction M (case length direction) of the cylindrical centerline m of the case body 51. The cleaning head 1 is housed inside the case body 51 by inserting the cleaning body 6 and each of the dust-collecting brushes 7 to 9 into the case body 51 through the opening P on one end 51A of the case body 51, with each of the dust-collecting brushes 7 to 9 facing one inner circumferential surface 51a (first inner circumferential surface) in the case thickness direction T1 of the case body 51.

[0077] As shown in Figure 15, the cleaning head 1 is housed in the case body 51 by inserting the first dust collection brush body 7 between one inner circumferential surface 51c in the case width direction W1 and the first guide projection 61. The cleaning head 1 is housed in the case body 51 by inserting the second dust collection brush body 8 between the other inner circumferential surface 51d in the case width direction W1 and the second guide projection 62. The cleaning head 1 is housed in the case body 51 by inserting the third dust collection brush body 9 between the guide projections 61 and 62. The protruding plate 11 to which the third dust collection brush body 9 is fixed is inserted between the guide projections 61 and 62. The first guide projection 61 is between the first dust collection brush body 7 and the third dust collection brush body 9, and is inserted between the first dust collection brush body 7 and the protruding plate 11. The second guide projection 62 is between the second dust collection brush body 8 and the third dust collection brush body 9, and is inserted between the second guide projection 62 and the protruding plate 11.

[0078] As shown in Figure 15, the cleaning head 1 is inserted into the case body 51 through an opening P on one end 51A of the case body 51, with the inclined directions of the inclined brush bristles F1 and F2 of the first and second dust-collecting brush bodies 7 and 8 perpendicular to the cylindrical centerline m of the case body 51.

[0079] As shown in Figures 12 to 15, the cleaning head 1 is housed inside the case body 51 by inserting the cleaning plate 10 and each dust collection brush body 7 to 9 into the case body 51 through the opening P on one end 51A of the case body 51, with the plate surface 10A of the cleaning plate 10 facing the other inner circumferential surface 51b (second inner circumferential side surface) in the case thickness direction T1 of the case body 51. The cleaning body 6 (cleaning plate 10) is inserted into the case body 51 between the guide protrusions 61, 62 and the press protrusions 63, 64, with the plate surface 10A of the cleaning plate 10 in contact with the press protrusions 63, 64. The cleaning head 1 is housed in the case body 51 by contacting the pressing protrusions 63, 64 of the cleaning plate 10, which press the inclined brush bristles F1, F2 of the first and second dust-collecting brush bodies 7, 8 against the inclined brush bristles H of the first and second dust-removing brush bodies 53, 54, and the upright brush bristles G of the third dust-collecting brush body 9 against the inclined brush bristles H of the third dust-removing brush body 55.

[0080] As shown in Figures 9, 12, and 15, the handle connector 2 and handle 3 are inserted into the case body 51 between the pressing protrusions 63 and 64, spaced apart on the other inner circumferential surface 51b (second inner circumferential surface) in the plate thickness direction T1, when the cleaning head 1 is housed inside the case body 51.

[0081] As shown in Figures 12 to 15, when the cleaning tool Y is inserted into the case body 51 with the cleaning head 1, handle connector 2, and handle 3, the inclined brush bristles F1 and F2 of the first and second dust-collecting brush bodies 7 and 8 slide against the inclined brush bristles H of the first and second dust-removing brush bodies 53 and 54, and the upright brush bristles G of the third dust-collecting brush body 9 slide against the inclined brush bristles H of the third dust-removing brush body 55, while the tool Y is moved relative to the case body 51 in the direction M of the cylindrical centerline m of the case body 51. The cleaning tool Y is moved relative to the case body 51 in the direction M of the cylindrical centerline m of the case body 51, while the inclined brush bristles F1 and F2 of the first and second dust-collecting brush bodies 7 and 8 are aligned perpendicular to the cylindrical centerline m of the case body 1, and the inclined brush bristles F1 and F2 of the first and second dust-removing brush bodies 7 and 8 are brought into sliding contact with the inclined brush bristles H of the first and second dust-removing brush bodies 53 and 54, and the upright brush bristles G of the third dust-collecting brush body 9 are brought into sliding contact with the inclined brush bristles H of the third dust-removing brush body 55.

[0082] As shown in Figures 12 to 14, when the cleaning head 1 is housed in the case body 51, it moves in the direction M of the cylindrical centerline m of the case body 51 relative to the case body 51.

[0083] As shown in Figures 12 to 14, the cleaning head 1 reciprocates in the direction of the cylindrical centerline m of the case body 51 while contacting the inclined brush bristles F1 and F2 of the first and second dust-collecting brush bodies 7 and 8 with the inclined brush bristles H of the first and second dust-removing brush bodies 53 and 54, and contacting the upright brush bristles G of the third dust-collecting brush body 9 with the inclined brush bristles H of the third dust-removing brush body 55. The cleaning head 1 reciprocates in the direction of the cylindrical centerline m of the case body 51 while contacting the plate surface 10A of the cleaning plate 10 with the pressing protrusions 63 and 64. The cleaning head 1 is moved while the dust-collecting brush bodies 7 to 9 are guided in the direction of the cylindrical centerline m of the case body 51 by the guide protrusions 61 and 62. As shown in Figures 12 to 14, the handle connector 2 and the handle 3 reciprocate in the direction M of the cylindrical centerline m of the case body 51 as the cleaning head 1 moves back and forth.

[0084] As shown in Figures 12 and 13, the first and second dust removal brushes 53 and 54 slide against the inclined brush bristles F1 and F2 of the first and second dust collection brushes 7 and 8 as the cleaning head 1 moves from the bottom 52 (other end 51B) of the case body 51 towards one end 51A (opening P), and the inclined brush bristles H of the first and second dust removal brushes 53 and 54 remove the dust captured by the inclined brush bristles F1 and F2 of the first and second dust collection brushes 7 and 8.

[0085] As shown in Figure 14, the third dust removal brush body 55, as the cleaning head 1 moves from the bottom 52 (other end 51B) of the case body 51 toward one end 51A, contacts each of the upright brush bristles G of the third dust collection brush body 9, and removes the dust captured by each of the upright brush bristles G of the third dust collection brush body 55 with each of the inclined brush bristles H of the third dust removal brush body 55.

[0086] The dust removed from each dust collection brush body 7 to 9 by each dust removal brush body 53 to 55 is accumulated at the bottom 52 on the other end 51B side of the case body 51. Once the dust has been removed from each dust collection brush body 7 to 9, the cleaning head 1, handle connector 2, and handle 3 are removed from the case body 51 and used to clean the surface FL. In this way, the cleaning unit X houses the cleaning head 1 inside the case body 51, and by moving the cleaning head 1 back and forth in the direction M of the cylindrical centerline m of the case body 51, the dust captured by each dust-collecting brush body 7 to 9 can be removed by each dust-removing brush body 53 to 55.

[0087] In the cleaning tool Y, the first and second dust-collecting brush bodies 7 and 8 may be configured to have at least two different thicknesses of inclined brush bristles. In the cleaning tool Y, one of the first dust-collecting brush body 7 or the second dust-collecting brush body 8 may have a plurality of first inclined brush bristles F1 and a plurality of second inclined brush bristles F, and the other of the first dust-collecting brush body 7 or the second dust-collecting brush body 8 may have a plurality of first inclined brush bristles F1 (inclined brush bristles). In the cleaning tool Y, the third dust-collecting brush body 9 may have the tips of each upright brush bristles G positioned in the same position (flush surface) as the first and second dust-collecting brush bodies 7 and 8 in the plate thickness direction T of the cleaning body 6.
