  The cover rotating means 61 and 62 are driven by compressed air when the user places the shoe on the cleaning unit 4 in a bad position by the shoe cover unit 20 or 21 from the top of the shoe. This is because safety is high even when pressure is applied to the legs. Note that the air filter 65 and the pressure reducing valve 66 are not indispensable constituent members in the present embodiment, but in order to reduce the failure of the flow path switching electromagnetic valve 68 and the cover rotating means 61 and 62 and to stabilize the operation. Provided.

  The flow path switching solenoid valve 68 has five connection ports on the outer surface of the flow path switching solenoid valve 68 (5 ports), and the power supplied to the flow path switching solenoid valve 68 from the control board 70 is turned ON / OFF. The flow path inside the flow path switching electromagnetic valve 68 can be switched.

  The compressed air sent from the air hose 67 is sent to the cover rotating means 61 and 62 from the two connection ports 68a and 68b through which any one of the flow path switching electromagnetic valves 68 communicates and sends the compressed air to the outside. The cover rotation means 61 is provided with two connection ports 61a and 61b, and the cover rotation means 62 is provided with two connection ports 62a and 62b. The connection port 61a of the cover rotation unit 61 and the connection port 62a of the cover rotation unit 62 are connected by an air hose 67 branched from the connection port 68a of the flow path switching electromagnetic valve 68. The connection port 61 b of the cover rotation means 61 and the connection port 62 b of the cover rotation means 62 are connected by an air hose 67 branched from the connection port 68 b of the flow path switching electromagnetic valve 68.

  When compressed air is sent to the connection port 61a of the cover rotation means 61 and the connection port 62a of the cover rotation means 62, the shoe cover portions 20 and 21 are in an upright state as shown in FIG. When compressed air is sent to the connection port 61b of the rotation means 61 and the connection port 62b of the cover rotation means 62, the shoe cover portions 20 and 21 are rotated about 90 degrees from each other in FIG. It will be in the state shown in the figure.

  In the present embodiment, the nozzle moving unit 57 is driven by an electric driving unit, and the cover rotating units 61 and 62 are driven by a pneumatic driving unit. However, the nozzle moving means 57 can be implemented by pneumatic or hydraulic driving means, and the cover rotating means 61 and 62 can be implemented by electric or hydraulic driving means.

  The control board 70 is mainly composed of a microcomputer, and when power is supplied from the outside, the control board 70 transmits and receives signals to and from the operation unit 7 that performs various settings with respect to the control board 50, and the high-pressure pump 50, electromagnetic switching The valve 51, the nozzle holder moving means 57, the flow path switching electromagnetic valve 68 and the like are controlled.

  The jet of water from the nozzle 90 will be described with reference to FIGS. FIG. 7 is an enlarged view of a part of FIG. 5, and the nozzle holder 56 is assumed not to move at the position shown in FIG. If the nozzle holder 56b is fixed at the position shown in FIG. 7, the shoe sole has irregularities such as a slip stopper and a protrusion of the heel. For example, for the depression 11a of the shoe sole, the nozzle 90b The water sprayed from is not directly hit.

  For this reason, if the nozzle holder 56b is fixed and the nozzle 90b does not move, unevenness will occur at the location where the shoe sole is washed with water. Even if the user moves the shoe side, there is a difference between good and bad cleaning depending on how it moves.

  Therefore, it is possible to clean the shoe sole with no unevenness by performing cleaning on the shoe sole in which the nozzle holders 56 and 56b are linearly moved from the heel side to the toe and returned to the heel side again. Is possible. In addition, even in the half process from linearly moving from the heel side to the toe, it is possible to clean the shoe sole without unevenness, but in this embodiment, the heel side is linearly moved from the heel side to the toe, and the heel is again It is carried out in one process to return to the side.

  FIG. 8 illustrates a state in which water is jetted from three outer-circular nozzles 90, 91, 92 from the upper side of the nozzle holder 56 to the shoe sole on one foot side. The nozzle 90 is provided with six spray holes 93 at locations corresponding to six corners of a regular hexagon. In addition, although only the nozzle 90 is attached with the reference numeral 93 for the spray hole by a lead line, the same applies to the nozzles 91 and 92, and the reference numeral 93 is omitted for the nozzles 91 and 92.

  Since the spray from the spray holes 93 has a predetermined spray angle (spray angle), water is sprayed from the six spray holes 93 in a conical shape. The range of water sprayed in a conical shape from the nozzles 90, 91, 92 to the shoe bottom is shown as a spray range 94. Further, the water sprayed in a conical shape between the adjacent spray holes 93 causes the water to collide with each other, thereby generating a portion having a large amount of linear water in the middle.

  FIG. 8 shows an example of the state of spraying water near the height of the shoe sole. The sides of the regular hexagon formed by the spray holes 93 of the nozzles 90, 91, 92 are preferably not parallel to the straight line along which the nozzle holder 56 moves. This is because the straight line formed by the six spray holes 93 does not overlap with the straight line along which the nozzle holder 56 moves.

  The numerical values are 27 centimeters and 24 centimeters, and the corresponding sizes of the start buttons 75, 76, and 77 are overlapped. This is a difference in the moving distance of the nozzle holder 56 due to the moving means 57. If the user selects the large size side activation buttons 75 and 76, there is no place where no washing is performed on the toe side of the shoe sole.

  The display unit 74 displays a two-digit numerical value. When the start button 75, 76, 77 is pressed, the time (seconds) until the cleaning is completed is displayed. When the cleaning is started, the countdown is performed. In addition to the countdown, the moving distance (centimeter) of the nozzle holder 56, the injection flow rate from the six nozzles, and these may be switched and displayed.

  The emergency stop button 73 is used when, for example, the user needs to stop the operation of the shoe sole cleaning device 1 after pressing the switch of the start button 75, 76, 77 described above. If a mistake is made, water injection is stopped, the position of the nozzle holder 56 is returned to the vicinity of the heel of the shoe sole, and the shoe cover portions 20, 21 are returned to the standing state as shown in FIG. 1 or FIG. .
