  The operation lever 60 includes a horizontal portion 61 that extends horizontally, a pivot attachment portion 62 that is provided on one end side (attachment portion 53 side) of the horizontal portion 61 and pivotally attached to the inner surface of the casing 51, and the horizontal portion 61. A handle portion 63 provided on the other end side (the opposite side of the attachment portion 53) and extending downward, and a locking protrusion 64 provided on the attachment portion 53 side of the horizontal portion 61 (rotation range adjustment mechanism) And comprising. When the user holds the handle portion 63 with the handrail 90 as a support, the operation lever 60 rotates in the direction of the attachment portion 53 to the handrail 90 around the pivotal attachment portion 62. Further, the handle portion 63 side of the operation lever 60 is urged upward in the figure, and the upper surface of the horizontal portion 61 contacts the first switch 10 in a non-operation state (a state where the user does not hold the handle portion 63). It is configured to touch.

  The adjustment screw 52 is screwed into a screw hole 54 provided downward from the upper side surface of the casing 51, and the position of the adjustment screw 52 is adjusted in the vertical direction by adjusting the amount of insertion of the adjustment screw 52 into the screw hole 54. The lower end of the adjustment screw 52 is configured to abut against a locking projection 64 provided on the operation lever 60 in a state where the user grasps the handle portion 63, thereby restricting the rotation range of the operation lever 60. . That is, the rotation range of the operation lever 60 can be adjusted by adjusting the position of the adjustment screw 52.

  A handle side end 71 of the cable 70 connected to the second switch 20 (FIG. 3) is locked to the handle portion 63 side of the horizontal portion 61 of the operation lever 60. In addition, the casing 51 is provided with a hole 55 for inserting the cable 70 corresponding to the position of the locking projection 64.

  FIG. 3 is an explanatory diagram showing the second switch 20 of the operating device 1 according to the first embodiment. The second switch 20 is disposed in the human body local washing device and is connected to the operation lever 60 via the cable 70 so as to be interlocked with the rotation operation of the operation lever 60. The second switch 20 includes a rod-shaped rotating rod 80.

The urging means 82 urges one end of the rotary rod 80 in a direction in which the cable 70 is pulled.

  The rotation shaft 81 of the second switch 20 is provided with a variable resistor (not shown) whose resistance value varies according to the rotation angle. It should be noted that any rotation detection sensor such as an encoder can be used in addition to the variable resistor as long as the rotation angle of the rotation shaft 81 can be detected to obtain a predetermined state value.

  Next, the operating principle when using the operating device 1 of the human body local cleaning device according to the first embodiment will be described in detail.

  In the non-use state, the upper side surface of the horizontal portion 61 of the operation lever 60 is in contact with the first switch 10 and the cable 70 is not pulled to the second switch 20 side. The first switch 10 is pushed by the upper side surface of the horizontal portion 61 and is in the off state. The control circuit 30 does not operate the flow rate adjusting device 40 when the first switch 10 is in the OFF state. At this time, on the second switch 20 side, the rotating rod 80 is urged by the urging means 82 in the direction of pulling the cable 70.

  From the non-use state, the user's palm is applied to the handrail 90 or the attachment portion 53 and the finger is hung on the operation lever 60 and pulled, whereby the operation lever 60 is gripped. It rotates in the direction of the attachment portion 53 as an axis. At this time, the upper side surface of the horizontal portion 61 is displaced downward, and the first switch 10 changes from the state pressed by the upper side surface of the horizontal portion 61 to the separated state, and is turned on. Then, the cable 70 locked to the operation lever 60 is pulled. On the second switch 20 side, the cable 70 is pulled toward the operation lever 60 side in conjunction with the rotation of the operation lever 60, so that the rotation rod 80 resists the urging force of the urging means 82. Rotate around the axis. And since the 1st switch 10 is an ON state, the control circuit 30 operates the flow volume adjustment apparatus 40, reads the resistance value of the variable resistor provided in the rotating shaft 81 of the 2nd switch 20, and resistance Wash water is spouted at a flow rate according to the value.

  Further, when the operation lever 60 is gripped and the operation lever 60 is rotated about the pivotally mounted portion 62, on the second switch 20 side, the rotation rod 80 rotates about the rotation shaft 81, and the variable resistor Resistance value fluctuates. Then, the control circuit 30 controls the flow rate adjusting device 40 so that the flow rate of the cleaning water gradually increases according to the change in the resistance value of the variable resistor. Finally, the locking projection 64 provided on the operation lever 60 comes into contact with the lower end of the adjustment screw 52, and the maximum rotation angle is set at which further rotation is restricted. The control circuit 30 reads the resistance value of the variable resistor provided on the rotation shaft 81 of the second switch 20 with respect to the maximum rotation angle, and the flow rate according to the resistance value becomes the maximum flow rate.

  When the grip of the operation lever 60 is loosened, the operation lever 60 rotates in the direction opposite to the attachment portion 53 with the pivoting portion 62 as an axis. On the second switch 20 side, the cable 70 is pulled by the rotating rod 80 urged by the urging means 82 in conjunction with the rotation of the operation lever 60. When the rotary rod 80 rotates about the rotation shaft 81, the resistance value of the variable resistor varies. Then, the control circuit 30 controls the flow rate adjusting device 40 so that the flow rate of the cleaning water gradually decreases according to the change in the resistance value of the variable resistor.

  As described above, in the operation device for the human body local cleaning device according to the first embodiment, the user can operate the first switch 10 and the second switch 20 only by rotating the operation lever 60. The washing water can be ejected, the washing strength can be adjusted, and the washing water can be stopped by a simple operation such as grasping the operation lever 60. Therefore, it is possible to adjust the cleaning strength to a desired level with a simple operation even for users who are not good at operating the machine or users who have weak physical strength such as elderly people or care recipients.

  Further, by disposing the first switch 10 on the operation lever 60 and disposing the second switch 20 on the human body local washing apparatus, the operation unit 50 that is a member including the operation lever 60 can be made compact. In addition, the second switch 20 is connected to the operation lever 60 via the cable 70, so that the place where the operation unit 50 is installed can be changed to a handrail, a shelf, a paper roll, a water supply / drain pipe, a hand washing facility, a water storage tank, a toilet It becomes possible to make it easy to operate, such as a bowl.

  Further, by adjusting the rotation range of the operation lever 60 with the adjusting screw 52 and the locking projection 64, the maximum value of the cleaning strength can be adjusted according to the user's preference.
