It consists of a handlebar 7 with a width of about 400mm for placing The handle bar 7 includes a cleaner start switch 8. The shoe cleaner 1 operates only while the user presses the start switch 8.

  As shown in FIG. 2, the shoe cleaner body 3 includes a cover 9 and a case 10. The side portion of the case 10 is provided with a detachable pull-out mud receiving tray 11 that is substantially the same shape as the bottom surface of the case 10 and that slides in the direction of the double arrow A to remove dust and dirt accumulated inside. ing. The mud receiving tray 11 can quickly dispose of the dust mud removed by cleaning, and the usable time of the shoe cleaner 1 can be further extended.

  The cover 9 is provided with an opening 12 having a width of about 200 mm and a depth of about 450 mm into which a user's shoes are inserted. A pair of guide rails 13 arranged in parallel at intervals of about 150 mm are provided on the inner side of the opening 12 and on the upper side of the case 10 (see FIG. 3) to prevent blurring of the inserted shoes. . Inside the case 10, a rotating brush 14 is provided on the lower side of the guide rail 13 so as to face upward.

  FIG. 3 shows a top view of the case 10 with the cover 9 of the shoe cleaner body 3 removed. A rotating brush 14 and a drive unit 15 for the rotating brush 14 are provided below the guide rail 13. The user inserts shoes between the guide rails 13 and places the shoes on the rotating brush 14 for cleaning. The drive unit 15 is mounted on two plate-like support frames 16 and 17 that are fixed slightly parallel to both sides of the case 10 slightly above the mud receiving tray 11. The rotary brush 14 is installed on the upper side of the drive unit 15 with the flocking material facing upward. The mud receiving tray 11 is provided below the two support frames 16 and 17 and can be pulled out in the horizontal direction of the drawing regardless of the state of the drive unit 15.

  FIG. 4 is a perspective view showing a state in which the rotary brush 14 and the drive unit 15 are taken out from the case 10 in order to explain the configuration of the rotary brush 14 and the drive unit 15. The rotating brush 14 includes a brush part 18, a centrifugal fan part 19, and a mud receiving part 20. The brush portion 18 includes a flocking material 21 and a brush base 22. The flocking material 21 is made of a material suitable for cleaning the bottom surface of the shoe, such as a large number of hair bundles or resin-made yarn bundles. The brush base 22 has a portion 23 where the flocking material 21 is flocked and an opening or cutout portion 24 (shown surrounded by a dotted line) for dropping dust mud downward. The centrifugal fan section 19 has a plurality of blades 25 extending radially, and a portion 23 of the brush base 22 where the hair transplant material 21 is implanted is radially along the blade 25 from the axial center toward the periphery. It is growing. In the present embodiment, the portion 23 of the brush base 22 to be implanted and the upper part of the blade 25 of the centrifugal fan section 19 are connected and integrally formed. However, for ease of understanding, the brush base is indicated by a dotted line in the figure. The boundary between 22 and the blade 25 is indicated by a dotted line. By adopting this configuration, the number of components can be reduced, and the manufacturing process can be simplified. The rotating brush 14 is made by, for example, a shaving, 3D printer, or a molding technique using a mold or the like.

  The drive unit 15 includes a drive motor 26 and a speed reducer 27. The speed reducer 27 changes the rotational axis of the drive motor 26 from the horizontal direction (downwardly rightward in the figure) to the upward direction (upward in the figure), and at the same time adjusts the rotational speed. Since the configuration of such a speed reducer is well known, detailed description thereof is omitted here.

  The mud receiving tray 11 shown in FIG. 3 collects dust mud that has been cleaned from the bottom of the shoe by the rotating brush 14 and has fallen from the mud receiving unit 20.

  FIG. 5 is a view of the rotating brush 14 and the drive unit 15 as viewed from the side. The mud receiving portion 20 of the rotating brush 14 has a conical shape provided coaxially with the brush portion 18. Adopting this shape makes it difficult for dirt and mud to collect on the upper surface portion.

  FIG. 6 shows an improved example of the brush portion 14 shown in FIG. The improved example is different in that a centrifugal fan unit 28 is used instead of the centrifugal fan unit 19. The shape of the centrifugal fan unit 28 as viewed from the side of the blade 29 is designed to be the same as the shape defined between the bottom of the brush base 22 and the upper surface of the mud receiving unit 20. By adopting this configuration, the area of the blade 29 is maximized, and the wind that goes radially from the shaft is increased. In this configuration, the lower portion of the blade 29 and the upper surface of the mud receiving portion 20 are connected and integrally formed. By adopting this configuration, the number of components can be reduced, and the manufacturing process can be simplified.

  FIG. 7 shows a modification of the rotating brush 14 shown in FIG. The brush portion 18 linearly connects a space between adjacent portions of the portion 23 to be planted radially extending, that is, an opening or a notch portion 24 for dropping dust mud downward, to prevent the intrusion of shoes. The prevention part 30 to prevent is provided. “Linear connection” means that the opening or notch portion 24 is not completely blocked, but is connected so as to bridge a part so as not to hinder the function of dropping dirt and mud downward. . Specifically, as shown in the figure, the prevention unit 30 is a plate-like material extending in a band shape without completely closing the opening or notch 24 in order to drop dust mud downward. By providing the prevention unit 30, a heel portion or a toe of a user's shoe is prevented from hitting the blade 25 (see FIG. 4) of the centrifugal fan unit 19.

  FIG. 8 is a perspective view of the rotary brush 14 and the drive unit 15 with this improvement. As shown in the figure, the prevention unit 30 has a thickness of about 1/3 of the width of the blade 25 of the centrifugal fan unit 19 and is integrally formed with the blade 25.

  The improvement related to the prevention unit 30 can be similarly applied to the improvement example of the rotating brush 14 shown in FIG.

  In addition, this invention is not restricted to the structure of the said various embodiment, A various deformation | transformation is possible in the range which does not change the meaning of invention. For example, the portion 23 of the brush base 22 to be implanted and the blade 25 of the centrifugal fan unit 19 may not be integrally formed. Similarly, the lower part of the blade 25 of the centrifugal fan part 19 and the upper surface of the mud receiving part 20 may not be integrally formed. By adopting this configuration, although the number of parts increases, for example, it is possible to control the brush base 22, the centrifugal fan unit 19, and the mud receiving unit 20 to rotate at high speed in this order. A technique for rotating a plurality of members arranged coaxially with a single drive source at different rotational speeds has already been established in a three-hand timepiece or the like, and will not be described in detail. By separating the brush base 22 and the centrifugal fan unit 19, for example, it is possible to form a sirocco fan or a turbo fan which is included in the centrifugal fan 19 and is well known. Further, the surface of the blade 25 of the centrifugal fan unit 19 and the upper surface of the mud receiving unit 20 may be subjected to water repellent treatment such as fluorine processing. By adopting such a configuration, it can be used for a longer time.

  The shoe cleaner of the present invention is mainly intended for cleaning the bottom surface of athletic shoes, but is not limited to this, and can also be used for boots for agricultural work. In addition, the rotating brush can be used for all types of cleaners that use a rotating brush on which a flocking material is placed upward.
