(Outline of shoe cleaning device)
The shoe washing apparatus 10 includes a waterproof housing 11 and adjusters 12 that are attached to the bottom four corners of the housing 11 and support the housing 11. The housing 11 is processed using a plate material (for example, a plate-like stainless material). Since the shoe cleaning apparatus 10 is configured to clean the shoe sole for one foot, it can be installed in a smaller space than that for brushing the shoe sole for both feet. In addition, the shoe cleaning device 10 includes a cleaning unit 20 and an electrical unit 30 provided in the housing 11. The cleaning unit 20 and the electrical unit 30 are provided separately from the viewpoint of waterproofing.

  The cleaning unit 20 is flushed with a water supply port (provided with a manual valve 21) for drawing a cleaning liquid (for example, general tap water) in connection with the outside of the apparatus (outside the casing 11), and the cleaning liquid after shoe sole cleaning. And a discharge port (a discharge pipe 22 is provided) for discharging to the outside of the apparatus. Moreover, the washing | cleaning part 20 is provided with the brush 40 which has the brushing surface 40a which brushes a shoe sole, and the drive part 50 which carries out the brushing drive of the brush 40, as shown in FIG. Further, the cleaning unit 20 includes a supply unit 60 that supplies the cleaning liquid to the brush 40 and a discharge unit 70 that is provided below (below) the brush 40 in the vertical direction Z and discharges the cleaning liquid by pouring. In the shoe cleaning apparatus 10, in the cleaning unit 20, brushing of the shoe sole is performed by the brush 40 supplied with the cleaning liquid by pouring.

  Here, the flow path L (showing a rough flow with a two-dot chain line in FIG. 5) until the cleaning liquid supplied from the supply unit 60 to the brush 40 is discharged by the discharge unit 70 is opened without being closed. Communicated. Therefore, the washed cleaning liquid can be discharged outside the apparatus without being stored inside the apparatus (inside the casing 11). If the cleaning liquid can be poured over the brush 40, for example, the cleaning liquid that has been poured through the storage section can be stored downstream from the discharge section 70.

  The supply unit 60 supplies the cleaning liquid supplied from the water supply port on the manual valve 21 side through the pipe 23 (see FIG. 3) such as a hose to the brush 40. Moreover, the supply part 60 is provided with the switching valve 24 (refer FIG. 3) provided in the middle part of the piping 23 at the water supply port side. In the supply unit 60, the cleaning liquid can be supplied to the brush 40 or the supply can be stopped by opening and closing the switching valve 24.

  The discharge unit 70 discharges the cleaning liquid supplied to the brush 40 from the discharge port. As shown in FIG. 5, the discharge unit 70 is provided at the lowest position of the cleaning liquid flow path L inside the apparatus, and one end communicates with the inside of the apparatus and the other end communicates with the outside of the apparatus (outside the casing 11). A tube 22 is provided. The discharge pipe 22 is processed using, for example, stainless steel. Further, the discharge unit 70 includes a detection unit 71 (see FIG. 5) such as a float switch provided in the lower direction than the brush 40 in the vertical direction Z. The detection unit 71 detects a state in which the cleaning liquid is not discharged due to dust clogging on the downstream side of the brush 40 in the flow path L. The discharge unit 70 can monitor the detection unit 71 and stop the supply of the cleaning liquid to the brush 40 in a state where the flowing cleaning liquid is clogged and accumulated.

  As shown in FIG. 1 or FIG. 3, the electrical component section 30 includes a power switch 31 having a circuit protector (which may also be used as a ground fault breaker), an external power cord 32, a ground fault protection relay 33, and a control section 34. And a sensor 35 and a warning (abnormal) lamp 36. The electrical unit 30 is supplied with power via an external power cord 32 and is turned on and off by turning on and off the power switch 31. When the power switch 31 is turned on, the shoe washing apparatus 10 enters a standby state (a power lamp 76 as shown in FIG. 10 may be provided to light up). The control unit 34 (for example, PLC: programmable logic controller) is protected by the circuit protector of the power switch 31 and the leakage protection relay 33.

  The control unit 34 is electrically connected to a sensor 35 (for example, a motion sensor) supplied with power. When a foot wearing shoes to be cleaned approaches in the standby state, the sensor 35 detects the human body. Further, the control unit 34 monitors the state of the sensor 35. Then, upon detecting the human body, the control unit 34 controls the start of brushing. In the shoe cleaning apparatus 10, automatic operation is performed so that it is operated only when the sensor 35 is detected. Note that manual operation can also be performed by providing a start switch for starting brushing instead of the sensor 35, for example.

  Further, the control unit 34 is electrically connected to the switching valve 24 (for example, a solenoid valve) supplied with power. Upon receiving the human body detected by the sensor 35, the control unit 34 opens the switching valve 24. As a result, the cleaning liquid flows out, and the cleaning liquid is supplied to the brush 40 by the supply unit 60.

  The control unit 34 is electrically connected to the drive unit 50 supplied with power. The control unit 34 drives the drive unit 50 after a predetermined time has elapsed since the switching valve 24 was opened. Specifically, the control unit 34 starts brushing in anticipation of the supply of the cleaning liquid to the brush 40. This is because if the shoe sole is washed without supplying the washing liquid to the brush 40, the washing effect is lowered. Further, by supplying the cleaning liquid to the brush 40 before brushing, even if dust is attached to the brush 40, the brushing can be started from the state where the dust is removed with the cleaning liquid to be poured. . During driving of the drive unit 50, the control unit 34 monitors the state of the drive unit 50 for overload protection of the drive unit 50.

  Further, the control unit 34 is electrically connected to the detection unit 71. When clogging occurs in the flow path L due to dust adhering to the shoe sole, the washed cleaning liquid is not discharged, and the detection unit 71 detects this. In response to detecting the clogging in the flow path L, the control unit 34 closes the switching valve 24 in order to stop the supply of the cleaning liquid.

  The control unit 34 is electrically connected to the warning lamp 36. When the detection unit 71 detects clogging, the control unit 34 turns on the warning lamp 36 in order to inform the user that the discharge pipe 22 is clogged and prompt cleaning. For this reason, the warning lamp 36 is provided on the outer surface of the casing 11 serving as the operation panel together with the power switch 31. Further, the control unit 34 turns on the warning lamp 36 when the driving unit 50 is overloaded.

  Using such a shoe cleaning apparatus 10, a user who wears a shoe to be cleaned cleans the sole of one foot (indicated by a broken line A in FIG. 1) with one foot raised, The sole of one foot can be cleaned in the same manner. At this time, the entire shoe sole can be washed by moving back and forth in the length direction of the shoe. According to the shoe cleaning apparatus 10 according to the present embodiment, since the cleaning liquid is used by pouring, the shoe sole can be brushed with the brush 40 constantly supplied with a new (clean) cleaning liquid, and the cleaning effect of the shoe sole can be improved. Can be improved.

(Details of shoe cleaning equipment)
As shown in FIG. 5, the brush 40 includes a brush base material 41 and a plurality of brush hairs 42 planted on the brush base material 41. The brush base 41 is made of a plastic member such as a vinyl chloride resin. The brush hair 42 is made of a fiber member such as nylon, for example. As shown in FIG. 6, the brush 40 has a brush base 41 formed in a disk shape (in FIG. 6, a transparent portion is indicated by a broken line), and radially from the center O (in FIG. 6, shown in 8 rows). ) Is arranged with the bristle 42. A brushing surface 40a (see FIG. 5) is formed by the tip of the brush bristles 42 arranged in this way.

  In the present embodiment, as shown in FIG. 5, the brush 40 is provided such that the brushing surface 40 a is inclined with respect to the horizontal direction Y at a predetermined angle θ (for example, about 15 °). FIG. 5 shows an inclination direction G as an example of the angle θ direction. Since the brushing surface 40a is inclined, the cleaning liquid containing dust can be easily discharged without stopping between the bristles 42, so that the dust can be prevented from adhering to the brush 40. Further, since the brush 40 is a rotating brush that is driven to rotate about the center O by the driving unit 50, the brushing surface 40a is a circular rotating surface. Since the brushing surface 40a has a circular shape, the shoe sole can be brushed in a planar shape, and the cleaning effect of the shoe sole can be improved.

  The drive unit 50 that rotationally drives the brush 40 has a rotation shaft 51 (motor shaft) as shown in FIG. The drive unit 50 is an electric motor such as an induction motor, for example. The brush 40 is connected to the rotation shaft 51 at the center O (see FIG. 6) of the brush base material 41. In the present embodiment, the rotation shaft 51 of the drive unit 50 is configured to be fitted into the brush 40. Specifically, a recess (not shown) is formed on the back surface of the brush base 41 opposite to the surface on which the brush hairs 42 are implanted (planted surface). The rotating shaft 51 is fitted. With such a configuration, the brush 40 can be easily exchanged (detached) with respect to the rotating shaft 51.

  Further, the drive unit 50 can rotate the brush 40 forward and backward under the control of the control unit 34. By rotating the brush 40 forward and backward, it is possible to prevent the bristles 42 from lying in one direction and extend the life of the brush 40. Further, by reversing the rotation direction of the brush 40 during brushing, dirt on the shoe sole is easily removed, and the cleaning effect can be further improved. Note that the forward / reverse rotation of the brush 40 may be controlled so as to switch the rotation direction for each cleaning (for example, for each foot).

  In addition, when the shoe sole is strongly pressed against the brush 40, the load on the rotating shaft 51 may become considerably large. In such a case, the current value flowing through the electric motor is monitored by the control unit 34, and the operation is stopped when a current greater than a certain value flows. Thereby, the burden of the electric motor can be reduced.

  In addition, the shoe cleaning apparatus 10 includes a plate 52 in order to protect the rotation shaft 51 of the drive unit 50. The plate 52 has an opening that is slightly larger than the circular brush base material 41, and is flush with the flocked surface of the circular brush base material 41 disposed so as to be concentric in the opening. It is provided to become.

  As shown in FIG. 5, the supply unit 60 includes a liquid discharge base 61 (sliding base) that is provided above the brush 40 in the vertical direction Z. The liquid discharge table 61 is inclined at a predetermined angle θ (inclination direction G) with respect to the horizontal plane direction Y, and has a liquid supply surface 61a (sliding surface, inclined surface) through which the cleaning liquid flows. That is, the liquid supply base 61 and the brush 40 are arranged in the inclination direction G with the liquid supply surface 61a as the upper side and the brushing surface 40a of the brush 40 as the lower side. For this reason, the liquid discharge table 61 discharges the cleaning liquid flowing from the liquid supply surface 61a toward the brush 40 (specifically, the brush bristles 42). And the brush 40 is provided in the lower direction (downward) of the inclination direction G of this liquid supply surface 61a. According to this, since the cleaning liquid flowing on the liquid supply surface 61a jumps out toward the brush 40 in a state where the cleaning liquid is arranged in a planar shape (a state spreading in the width direction), the cleaning liquid can be supplied to the brush 40 over a wide range.

  As described above, the brush 40 has the circular brushing surface 40a. For this reason, in the present embodiment, the width W of the liquid supply surface 61a (see FIG. 8), that is, the liquid supply surface on the brush 40 side is used in order to allow the cleaning liquid discharged from the liquid discharge table 61 to reach the wide area of the brush 40. The length of the end of 61a is made longer than the diameter of the brushing surface 40a. Further, as shown in FIG. 8, the liquid discharge table 61 has side walls 61b on both sides of the liquid supply surface 61a. The side wall 61b can prevent the cleaning liquid from protruding (leaking) from both sides of the liquid supply surface 61a.

  By the way, as shown in FIG. 1, the liquid supply surface 61a of the liquid discharge table 61 is used as a toe mounting surface on which the toe portion of the shoe sole is mounted. For this reason, although the cleaning liquid is not directly supplied toward the brush 40 from the portion where the shoe sole is placed on the liquid supply surface 61a of the liquid discharge table 61, the cleaning liquid is supplied to the brush 40 along the shoe sole. The On the other hand, the washing | cleaning part 20 is provided with the grating 25 as a heel mounting surface which mounts the heel part of a shoe sole. That is, the liquid discharge table 61 (for example, the toe portion is located), the brush 40 (for example, the arch portion), and the grating 25 (for example, the heel portion) toward the lower side (downward) of the inclination direction G of the liquid supply surface 61a. They are provided in this order.

  The liquid supply surface 61a (toe mounting surface) of the liquid discharge table 61 and the surface of the grating 25 (heel mounting surface) are flush with each other (in the same plane) so that the shoe sole is stably mounted. Provided. And the brush 40 is provided so that the front-end | tip of the bristle 42 may protrude about 5 mm, for example from the same surface which a toe mounting surface and a heel mounting surface make (refer FIG. 5). For this reason, the brushing surface 40a is parallel to the same surface vertically above (upper) the same surface formed by the toe mounting surface and the heel mounting surface. Therefore, for example, even if the shoe sole toe part is placed on the liquid discharge base 61 (liquid supply surface 61a) and the shoe sole heel part is placed on the grating 25, the arch part (central part) of the shoe sole is placed. Brushing is performed in contact with the brushing surface 40a.

  Here, the inclined angle θ (see FIG. 5) formed by the liquid supply surface 61a and the horizontal plane direction Y is set so that the cleaning liquid flowing on the liquid supply surface 61a reaches the brush 40 by its own weight. However, if the inclination angle θ is too large, the splashing of the cleaning liquid that reaches the brush 40 becomes large. For this reason, in the present embodiment, the inclination angle θ is set to 15 ° to 20 °.

  The cleaning unit 20 (shoe cleaning apparatus 10) includes scattering prevention plates 26 and 27 in order to prevent the cleaning liquid from splashing and splashing outside. For example, when the shoe sole is strongly pressed against the brushing surface 40a, the amount of bending of the bristles 42 increases, and the splashing of the cleaning liquid due to the reaction may be serious. Therefore, the scattering prevention plates 26 and 27 are provided to prevent the user's feet from being soiled.

  The scattering prevention plate 26 is a flexible plate such as a rubber plate, for example. The anti-scattering plate 26 is provided above the brushing surface 40a in the vertical direction (upper direction) and in parallel with the brushing surface 40a, exposing the central portion of the brushing surface 40a. The scattering prevention plate 27 is a plastic plate such as a PET (polyethylene terephthalate) plate. The scattering prevention plate 27 is provided upright in the vertical direction Z on the casing 11 on the side of the grating 25, which is below (lower level) the tilt direction G. The scattering prevention plate 27 is formed with a bent portion 27a that is bent toward the grating 25 side. For example, the bent portion 27a can further prevent the cleaning liquid from splashing from the heel portion of the shoe sole.

  As shown in FIGS. 3 and 7, the supply unit 60 extends in parallel with the horizontal plane direction X at the upper part of the liquid supply surface 61a of the liquid discharge table 61 (in a direction intersecting the inclined direction G of the liquid supply surface 61a). A pipe 62 extending). The pipe 62 has a plurality of discharge ports 62 a provided side by side in the length direction of the pipe 62. Then, both ends of the pipe 62 are connected to each of the pipes 23 branched into two. Therefore, the cleaning liquid is supplied from both ends of the pipe 62 to the inside of the pipe 62, and the cleaning liquid is discharged from the plurality of discharge ports 62a.

  In addition, the supply unit 60 includes a storage unit 63 that is provided on the liquid supply surface 61 a of the liquid supply base 61 and stores the pipe 62. The accommodating portion 63 has an opening 63 a that opens toward the lower side of the liquid supply surface 61 a of the liquid supply base 61. More specifically, the accommodating part 63 has an opening 63a formed on the liquid supply surface 61a in the wall part on the brush 40 side and opening so as to extend in the length direction of the pipe 62 (horizontal plane direction X). . Therefore, as shown in FIG. 7, the cleaning liquid is discharged from the discharge port 62a of the pipe 62 toward the inner wall of the accommodating portion 63, and the cleaning liquid that reaches the liquid supply surface 61a along the inner wall reaches the opening 63a. Flows out of. The arrows in FIG. 7 indicate the direction in which the cleaning liquid flowing out from the pipe 62 flows.

  By accommodating the pipe 62 provided with a plurality of discharge ports 62a in the length direction of the pipe 62 in such a housing part 63, the amount of the cleaning liquid can be leveled and the cleaning liquid can flow out from the opening 63a. The cleaning liquid can be supplied to the brush 40 by flowing the cleaning liquid over a wide range of the liquid supply surface 61a.

  In the present embodiment, as shown in FIG. 9, in the opening 63a (see FIG. 8) extending in the horizontal plane direction X, the height near the center is gradually increased from both sides. That is, the central height H1 of the opening 63a (the height from the liquid supply surface 61a indicated by the broken line in FIG. 9) is higher than the heights H2 on both sides of the opening 63a. According to this, it becomes easier for the cleaning liquid to flow near the center than on both sides of the liquid supply surface 61 a, and a large amount of cleaning liquid can be supplied toward the center of the brush 40.

  In the present embodiment, the plurality of discharge ports 62 a are arranged in the longitudinal direction of the pipe 62 so as to open upward in the vertical direction Z. The inner wall of the storage portion 63 with which the cleaning liquid discharged from the vertical discharge port 62a in the vertical direction Z abuts is the ceiling (inner wall) farthest from the liquid supply surface 61a of the liquid discharge table 61 among the inner walls of the storage portion 63. By discharging the cleaning liquid toward the ceiling, it is possible to suppress the momentum of the cleaning liquid when reaching the liquid supply surface 61a.

  As shown in FIG. 5, the discharge unit 70 includes a liquid discharge stand 74 provided in the middle of the flow path L until the cleaning liquid supplied to the brush 40 is discharged. The liquid discharge table 74 is inclined at a predetermined angle θ (inclination direction G) with respect to the horizontal plane direction Y, and has a liquid discharge surface 74a through which the cleaning liquid flows. The drive unit 50 is provided on the liquid discharge surface 74a so that the vertical direction of the liquid discharge surface 74a coincides with the axial direction of the rotary shaft 51. For this reason, the brushing surface 40a of the brush 40 attached to the rotating shaft 51 and the liquid discharge surface 74a are parallel. That is, by adjusting the inclination angle of the liquid discharge surface 74a, the inclination angle of the brushing surface 40a of the brush 40 can be adjusted (both become the angle θ).

  The discharge unit 70 is provided in the middle of the flow path L until the cleaning liquid supplied to the brush 40 is discharged, and drops the cleaning liquid flowing from the liquid discharge surface 74a of the liquid discharge table 74 in the vertical direction Z.
