When the paper presser 64a is bent, first, the left front presser 81 and the right front presser 82 first press the toilet paper from the front side of FIG. This prevents the toilet paper from shifting to the back side in FIG. 3 during the paper pressing operation. Since the left front pressing part 81 and the right front pressing part 82 are elastic members, when the paper pressing tool 64a is rotated and bent as it is, the left front pressing part 81 and the right front pressing part 82 are also bent together. . Then, the insertion portion 83 is inserted between the fixed convex portion 54 and the movable convex portion 53. Since the tip of the insertion portion 83 is tapered as shown in FIG. 17, the insertion is performed smoothly. After the insertion part 83 is inserted, the left shaping part 84 and the right shaping part 85 hold down the left and right sides of the toilet paper. Furthermore, the left back shaping part 87 and the right back shaping part 88 hold down the left and right of the back side of the toilet paper. Since the hollow shape formed by the left shaping part 84, the right shaping part 85, the left back shaping part 87, and the right back shaping part 88 is along the shape of the opening / closing part by the fixed convex part 54 and the movable convex part 53, When the toilet paper is inserted into the paper gripping part 51, the toilet paper is shaped on the upper surface of the paper gripping part 51, and the toilet paper is prevented from jumping upward. Thus, the paper pressing tool 64a has a shape that follows the shape of the opening / closing portion formed by the fixed convex portion 54 and the movable convex portion 53 so as to shape the toilet paper. After the insertion of the insertion portion 83 is completed, the movable convex portion 53 is closed and the toilet paper is gripped. With the force for closing the movable convex portion 53 applied to the actuator, the motor of the paper pressing portion 64 rotates in the reverse direction, the paper pressing tool 64a bends in the reverse direction, and the insertion portion 83 is extracted. Since the distal end of the insertion portion 83 is tapered, the extraction operation is performed smoothly.

  FIG. 18 is a schematic cross-sectional view showing the structure of the automatic paper feeder 6. The automatic paper feeding unit 6 includes a plurality of rotors 75 for placing the toilet paper 74 in a rotatable manner, a paper piece detecting unit 61, a paper feeding unit 62, and a paper cutting unit 63.

The toilet paper inserted into the paper insertion opening 70 is inserted into the gap between the fixed blade 73 and the movable blade 72. The toilet paper inserted in the gap between the fixed blade 73 and the movable blade 72 is placed on the paper platform 64a (on the paper gripper 51). The whole is designed to have such a positional relationship. Since the plate member 64d stands on the left and right sides of the paper platform 64a, the toilet paper placed on the paper platform 64a is bent and contacts either the left or right side of the plate member 64d. The toilet paper is bent and sequentially placed on the paper table 64a in a folded state by contacting the other plate member 64d and repeating this. When a predetermined amount of toilet paper is fed out, the toilet paper is cut by the paper cutting unit 63.

  When the lever 65 is moved downward with the fulcrum 71 as a fulcrum, the movable blade 72 moves upward so as to rub against the fixed blade 73. Thereby, the toilet paper between the movable blade 72 and the fixed blade 73 is cut. In order to move the lever 65 downward, the rotating shaft of the cutter drive motor 68 rotates to rotate the drive cam 69, and the protrusion 66 or 67 pushes down the lever 65, so that the toilet paper is cut. When the lever 65 is pushed down to the lowest position by the protrusion 66 or 67, the protrusion 66 or 67 does not come into contact with the lever 65. A spring (not shown) is attached to the lever 65, and when the lever 65 and the projection 66 or 67 are not in contact with each other, the lever 65 is automatically pushed upward. When the cutting of the toilet paper is completed, the cut toilet paper is placed on the paper platform 64a (on the paper gripping portion 51), and the toilet paper is pressed by the paper pressing portion 64, so that the paper gripping portion 51 is placed. To grab toilet paper.

  The paper breakage detection unit 61 is, for example, an infrared sensor, an optical sensor, an ultrasonic sensor, or the like, and detects whether or not toilet paper remains in the vicinity between the rotor 75 and the paper feeding unit 62 in FIG. If toilet paper remains after cutting, the toilet paper should be present near the space between the paper feed unit 62 and the rotor 75.

Moreover, the warm water washing | cleaning detection part 100 may detect whether the sound at the time of warm water washing | cleaning was detected with the microphone. In addition, the warm water washing | cleaning detection part 100 may detect that the nozzle of the warm water washing | cleaning apparatus was extended by various sensors. The method for detecting the completion of the hot water cleaning by the hot water cleaning detection unit 100 does not limit the present invention. If the hot water cleaning has not been completed, the control unit 7 causes the audio output unit 9 to output a sound such as “please clean with hot water” (step S102). It will be in a standby state until hot water washing is completed. Here, the completion of the hot water cleaning is used as the trigger for starting the operation. However, the timing when the operation switch 8 is pressed by the user may be used as the trigger for starting the operation. In, it is not essential.

  When the hot water cleaning is finished, the control unit 7 determines whether or not the wiping arm 5 is located at a predetermined standby position (home position) (step S103). Based on the signal from the position detection unit 35, the control unit 7 detects whether or not it is a standby position. For example, when the position of the first center 35a is set as the standby position, the controller 7 determines that the wiping arm 5 is positioned at the standby position when the slide base 31b is detected by the first sensor 35a. Judgment can be made. In addition, the position of the second or third sensor 35b, 35c may be set as the standby position. When it is determined in step S103 that the wiping arm 5 is not positioned at the standby position, the control unit 7 drives the necessary motor of the wiping arm driving unit 3 so as to be positioned at the standby position, thereby wiping the arm 5. Return to the standby position.

  Next, the control unit 7 causes the voice output unit 9 to output a start voice such as “start” (step S105). Next, the control unit 7 sends an electrical signal to the actuator of the paper gripping unit 51 to drive the movable convex portion 53 in the opening direction (step S106). In the present embodiment, the movable convex portion 53 is in a freely moving state when not being driven by the actuator. For example, a spring or the like is attached to the movable convex portion 53, and the actuator In a state in which the toilet paper is not driven, the toilet paper may be easily removed by applying a force to the movable convex portion 53 in the always opening direction. On the contrary, in the state where it is not driven by the actuator, it is possible to make it difficult to remove the toilet paper by always applying a force to the movable convex portion 53 in the closing direction.

  Next, the control unit 7 causes the voice output unit 9 to output a toilet seat raising sound such as “the toilet seat is raised” (step S107), and controls the toilet seat lifting device 2 to raise the toilet seat (step S108). . Next, the control unit 7 drives the various motors of the wiping arm driving unit 3 to move the wiping arm 5 to the paper gripping position (step S109). In the example shown in FIG. 3, the paper gripping portion 51 is a state where the paper gripping portion 51 is positioned below the paper placing base 64b. Therefore, specifically, the control unit 7 controls the front / rear drive unit 31 to move the slide base 31b to the position of the second sensor 35b, and controls the vertical drive unit 33 to cut the paper gripping unit 51. Tilt down the notch 64c.

  After the wiping arm 5 moves to the paper gripping position, the control unit 7 controls the paper feeding unit 62 to send out the toilet paper (step S110). After the predetermined amount of feeding is performed, the control unit 7 controls the paper cutting unit 63 to cut the toilet paper (step S111). Next, the control unit 7 determines whether or not toilet paper remains based on the signal from the paper breakage detection unit 61 (step S112). When the toilet paper does not remain, the control unit 7 causes the audio output unit 9 to output a paper-out sound such as “paper has run out” and prompts the user to replace the paper (step S113). It will be in a standby state until the paper replacement is completed. When the toilet paper is used up, the control unit 7 may return to the standby position after the announcement and wait until a wiping instruction is issued again.

  When the toilet paper remains, the control unit 7 controls the paper holding unit 64 to hold the toilet paper, controls the paper gripping unit 51, closes the movable convex portion 53, and holds the toilet paper. (Step S114). Next, the control part 7 controls each motor of the wiping arm drive part 3, and moves the wiping arm 5 to a rotation position (step S115). Specifically, the control unit 7 controls the vertical driving unit 33 to move the wiping arm 5 above the notch 64c, and controls the front / rear driving unit 34 to move the wiping arm 5 to the first sensor. It moves backward to the position of 35a. The rotation position is not particularly limited, and is a position where the wiping arm 5 can be rotated and inserted into the gap between the toilet seat and the toilet bowl in consideration of the size of the water tank and the shape of the toilet seat lifting / lowering device 2. That's fine.

  After step S115, the control unit 1 determines whether or not the paper gripper 51 is gripping the toilet paper based on the signal from the paper grip detection unit 52 (step S116). Before the wiping arm 5 rotates and is exposed to the toilet seat opening, the determination in step S116 is performed, and it is detected that the toilet paper may have been detached due to some trouble when the wiping arm 5 moves backward. Thus, it is possible to prevent the wiping arm 5 to which the toilet paper is not attached from coming into contact with the buttocks. If the toilet paper is not gripped, the control unit 7 causes the voice output unit 9 to output a paper trouble voice such as “I do not grip the paper” (step S117), and returns to the operation of step 109. Repeat the operation. In addition, since toilet paper may remain somewhere inside the heel wiping apparatus 1, the control unit 7 may end the operation after step S117.

  When the toilet paper is gripped in the rotation position stage, the control unit 7 controls the cover driving unit 41 to rotate the cover unit 4 in the toilet seat direction, and then controls the rotation driving unit 32. Then, the wiping arm 5 is rotated so that the paper to which the toilet paper is attached passes under the cover unit 4 so that the wiping arm 5 is exposed to the toilet seat opening, and the cover driving unit 41 is controlled to cover the cover unit. 4 is restored (step S118). After step S118, the control unit 7 determines whether or not the paper gripper 51 is gripping the toilet paper based on the signal from the paper grip detection unit 52 (step S119). By this, when the wiping arm 5 rotates, it is possible to detect the possibility that the toilet paper has been removed due to some trouble, and to prevent the wiping arm 5 to which the toilet paper is not attached from coming into contact with the buttocks. it can. If the toilet paper is not grasped, the control unit 7 causes the audio output unit 9 to output a paper trouble sound such as “I do not grasp the paper” (step S120), and returns to the operation of step 109. Repeat the operation. In addition, since there is a possibility that the toilet paper remains somewhere inside the heel wiping device 1, the control unit 7 may end the operation after step S120.

  It should be noted that it may be detected whether or not the toilet paper is gripped at a timing other than steps S116 and S119, and an interrupt process may be performed to detect that the toilet paper is not gripped. If it is not gripped, the wiping operation should be stopped.

  After step S119, the wiping arm 5 is exposed from the toilet seat opening with the toilet paper attached normally. In this state, the control unit 7 controls the voice output unit 9 to output a wiping start voice such as “please press the wiping switch” (step S121). Note that the operation in step S121 may be performed in place of the operations in steps S101 and S102 or before or after the operations in steps S101 and S102. The operation switch 8 operates for men, for women, from the front (operation when the anus is in front of the toilet seat), and from the back (operation when the anus is behind the toilet seat). ), A standard operation, the number of times of wiping, the pressure of wiping, the movement of wiping, the range of wiping, and the like, may be configured by a switch that can select an operation according to the wiping preference. Of course, the operation switch 8 may be configured by a switch that performs only one type of operation. Further, the wiping arm 5 may be controlled to a desired movement by a manual operation.

  When the user depresses the wiping switch of the operation switch 8 (step S122), the control unit 7 causes each motor of the wiping arm driving unit 3 to operate the paper gripping unit 5 according to the instructed operation. Is controlled (step S123). At this time, the control unit 7 controls the front / rear drive unit 31 to move the paper gripping unit 5 back and forth, controls the vertical drive unit 33 to move up and down, and controls the rotation drive unit 32 to move left and right. If it is desired to add torsion, the tilt drive unit 34 is controlled. In this manner, the wiping operation is performed from the start to the end.

  After the wiping operation is completed, the control unit 7 controls the vertical driving unit 33 to release the contact with the collar with the wiping arm 5 facing downward, to control the tilt driving unit 34, and to the paper gripping unit 51. Is turned over (step S124), the paper gripper 51 is controlled, the movable convex part 53 of the paper gripper 51 is opened (step S125), and the toilet paper is dropped. At this time, the control unit 7 controls the vertical driving unit 33 with the paper gripping unit 51 turned upside down to apply acceleration in the vertical direction to the wiping arm 5 so as to shake off the toilet paper. May be.

  After step S125, the control unit 7 controls each motor of the wiping arm driving unit 3 to store the wiping arm 5 in the buttock wiping device 1 (step S126).

  In order to clean the wiping arm 5, a maintenance switch is provided in the operation switch 8. When the maintenance switch is pressed, the control unit 7 sets the wiping arm 5 to the toilet seat opening without toilet paper attached. It should be exposed.
