  The guide portion 25 is formed by grooves formed above and below the head entrance / exit 3a, and guides the shutter 23 entering / exiting from the inner wall of the interposition portion 3 in the longitudinal direction along the head entrance / exit 3a. The inner wall of the interposition part 3 is a double wall, and the shutter 23 is stored between the walls of the double wall when the head entrance 3a is opened. In addition, in the inner periphery of the interposition part 3 shown in FIG. 12, the head entrance 3a and the guide part 25 are formed in the part where the outline is thin, and 2 in the part where the outline is thick. A heavy wall is formed.

  The head disinfection device 20 is provided for disinfecting the head 4. For example, as shown in FIG. 11, the head disinfecting apparatus 20 includes a disinfecting liquid storage container 29 for storing disinfecting liquid, a disinfecting liquid amount sensor 77, a disinfecting liquid supply pipe 78, a disinfecting liquid supply pump 85 (not shown in FIG. 11). ) Etc. The disinfecting liquid storage container 29 is installed on the rear surface of the apparatus casing 17, and the disinfecting liquid supply pipe 78 passes through the inside of the interposition part 3 from the bottom of the disinfecting liquid storage container 29 to the excretion opening 14 of the interposition part 3. Is arranged. The distal end portion of the disinfecting liquid supply pipe 78 is directed to a “head cleaning position” to be described later. When the disinfecting liquid supply pump 85 is operated, the disinfecting liquid in the disinfecting liquid storage container 29 passes through the disinfecting liquid supply pipe 78 “ Jetted to the head 4 at the “head cleaning position”. Thereby, the head 4 is cleaned and disinfected.

  Further, a blower 83 and a blower duct 84 are installed in the interposition part 3. The blower 83 and the blower duct 84 blow outside air sucked from an intake port (not shown) toward the head 4 at the “head cleaning position”, and dry the wet head 4 by spraying the cleaning liquid.

  The announcement unit 74 (see FIG. 6) generates a predetermined error message when various errors occur. The error lamp display section 75 (see FIG. 6) turns on a predetermined lamp to notify various errors.

  Next, the operation of the automatic moisture wiping device 1 for the buttocks will be described based on the flowcharts of FIGS. 14 and 15. Note that, as an initial state before the start of the wiping operation, the arm 6 is stored in the apparatus casing 17 in a substantially front-rear direction, and the head 4 has the paper gripping function released and the floor surface 64 of the automatic sheet feeder 61 is released. It is assumed that this is placed on top (hereinafter, this position is also referred to as “initial position”). Further, the operation of turning off the main power switch 72 in step ST4 to be described later is executed when a serious problem in which the apparatus 1 cannot be used occurs. Before the main power switch 72 is turned on again, the display, This is done to promote the resolution of problems reported by announcements.

  When the main power switch 72 of the entire toilet apparatus including the automatic moisture wiping device 1 and the warm water washing device 12 is turned on, the control unit 54 determines whether or not the head 4 is stored in the initial position. The determination is made based on the output signal of the detection sensor 73. If an affirmative determination is made in this step, the process proceeds to step ST2, and if a negative determination is made, a lamp indicating a head storage error in the error lamp display section 75 is turned on (step ST3), and the main power switch 72 is turned off (step ST3). Step ST4).

  In step ST <b> 2, the control unit 54 determines whether the head entrance 3 a is closed by the shutter 23 based on the output signal of the shutter opening / closing sensor 28. When an affirmative determination is made here, the process proceeds to step ST5, and when a negative determination is made, the head entrance / exit opening / closing motor 26 is driven to close the head entrance 3a with the shutter 23 (ST6).

  In step ST5, the toilet paper folded on the head 4 is set. Specifically, the control unit 54 sends a paper feed command to the paper supply control unit of the automatic paper supply device 61, and the paper supply control unit that receives the command places the toilet paper folded on the head 4. . Then, from the state where the rotating arm 68 is in the “retracted position” as shown in FIG. 9, the control unit 54 drives the paper insertion servomotor 67, and as shown in FIG. The toilet paper 10 is inserted between the two members 18 and 19 of the head 4 by the insertion plate 69. Thereafter, the control unit 54 rotates the first servo motor 35 by a predetermined amount, pulls the distal end side of the operation wire 21 (see FIG. 3) toward the arm 6 side, and separates the fixing surface 18 of the head 4 and the dividing surface 18b of the occlusal portion 19. , 19b are brought close to each other and the toilet paper 10 pushed by the insertion plate 69 between them is grasped.

  In step ST7, the control unit 54 waits until the toilet user performs an ON operation of the wiping start switch 76. When the switch 76 is turned on, the presence / absence of the disinfecting liquid is determined based on the output signal of the disinfecting liquid amount sensor 77 (step ST8). If an affirmative determination is made here, the process proceeds to step ST9. If a negative determination is made, an error lamp without an antiseptic solution in the error lamp display section 75 is turned on (step ST10), and the main power switch 72 is turned off (step ST4). ).

  In step ST <b> 9, the control unit 54 determines whether there is a remaining amount of the toilet paper 10 based on the output signal of the remaining paper amount detection sensor 79. As the remaining paper amount detection sensor 79, an optical sensor that distinguishes between the white color of toilet paper and the non-white color (brown color) of the toilet paper core is used. If an affirmative determination is made here, the process proceeds to step ST11. If a negative determination is made, an error lamp without toilet paper in the error lamp display section 75 is turned on (step ST12), and the main power switch 72 is turned off (step ST4). ).

  In step ST11, the control unit 54 determines whether or not the buttock has been cleaned. In the present embodiment, this determination is made by a nozzle detection sensor 81 that detects a state in which the anal cleaning nozzle 80 (or bidet cleaning nozzle) of the hot water cleaning device 12 shown in FIG. 7 protrudes from the toilet seat 11 to the excretion opening 13. If the nozzle 80 is retracted and stored on the back of the toilet seat 11 after using the hot water cleaning function, it is determined that the buttock has been cleaned if it is within a predetermined time (for example, within 1 minute), otherwise it is not cleaned. Is determined. If an affirmative determination is made in this step, the process proceeds to step ST12. If a negative determination is made, the announcement unit 74 makes an announcement that the buttocks are not washed (step ST13), and turns off the main power switch 72. (Step ST4).

  In step ST <b> 12, the control unit 54 moves the head 4 from the initial position to the front of the head entrance 3 a closed by the shutter 23. That is, the controller 54 first rotates the linear drive motor 48 to move the linear slider 45 and the head 4 mounted thereon to the foremost position where the slider 45 is detected by the first limit switch 51. Move forward. Next, by rotating the third servo motor 38 by a predetermined amount, the head 4 and the arm 6 are rotated about the vertical axis M, and as shown by a two-dot chain line in FIG. To move.

  In step ST14, the control unit 54 determines whether or not the head 4 is holding the toilet paper based on the output signal of the paper grip detection sensor 82. As the paper grip detection sensor 82, for example, a sensor that optically detects the toilet paper 10 that protrudes around the head 4 is used. If an affirmative determination is made in this step, the process proceeds to step ST15. If a negative determination is made, the announcement unit 74 announces a paper grip error (step ST16) and turns off the main power switch 72 (step ST4).

  In step ST15, the control unit 54 drives the head entrance / exit opening / closing motor 26 to slide the shutter 23 in the fully closed position in the opening direction to open the head entrance 3a.

  In step ST16, the control unit 54 determines whether or not the head entrance 3a is fully opened based on the output signal of the shutter opening / closing sensor 28. If an affirmative determination is made here, the process proceeds to step ST17. If a negative determination is made, the announcement unit 74 makes an announcement that the shutter has not been opened (step ST18), and turns off the main power switch 72 (step ST18). ST4).

  Next, in steps ST <b> 17 and ST <b> 19 to ST <b> 22, the control unit 54 executes a moisture wiping process for the heel part.

  In step ST17, the control unit 54 rotates the third servo motor 38 by a predetermined amount until the arm 6 reaches approximately 90 ° with respect to the front-rear direction of the toilet as shown by the solid line in FIG. And the arm 6 is rotated around the vertical axis M, and the head 4 is moved to the “wiping operation start position” in the excretion opening 14 (in the excretion area). However, when the head 4 passes through the position overlapping the toilet seat 11 when viewed from above during the rotation operation, the head 4 has the second servo so that the eccentric direction of the head 4 with respect to the axis N is substantially horizontal. The rotational position of the motor 36 is maintained.

  In step ST19, the control unit 54 rotates the second servo motor 36 by a predetermined amount, thereby rotating the arm 6 by a predetermined amount around the axis N to raise the head 4 at the “wiping operation start position”. By this operation, the head 4 is in a state in which the eccentric direction is inclined by a predetermined angle with respect to the substantially horizontal direction as shown in FIG. 4B from the state in which the eccentric direction is substantially horizontal as shown in FIG. The head 4 (especially the centrifugal side of the head 4) is disposed at a high position so as to hit the user's buttocks. However, in FIG. 4, the illustration of the toilet paper being grasped is omitted. The predetermined angle for rotating the arm 6 and the head 4 about the axis N is a predetermined angle within a range of 0 ° to 90 °, and the predetermined angle is preferably about 40 ° to 60 °, and further Preferably, it is about 50 °.

  In step ST20, the control unit 54 rotates the linear drive motor 48 to move the linear slider 45 and the head 4 mounted on the linear slider 45 backward (that is, the eccentricity of the head 4 with respect to the axis N). While the head 4 is moved rearward in a state in which the direction forms an obtuse angle with respect to the traveling direction), the toilet paper 10 held by the head 4 that has risen is wiped off the water adhering to the buttock. During this operation, the head 4 and the arm 6 move from the position shown in FIG. 12 to the position shown in FIG. 13 (position where the slider 45 is detected by the second limit switch 52). By the way, while the head 3 is moving backward, the second servo motor 36 is controlled so as to maintain a predetermined target rotational position, and the head 4 hits the buttocks and the arm 6 moves in the opposite direction by the reaction force. When rotating around the axis N, the second servo motor 36 performs a rotation operation to return to the target rotation position with a preset torque. For this reason, it is possible to adjust the hitting strength against the buttocks by changing the setting value of the magnitude of the torque and the head rising amount (target rotational position).

  In step ST <b> 21, the control unit 54 rotates the first servo motor 35 by a predetermined amount to push the distal end side of the operation wire 21 from the arm 6. As a result, the occlusal portion 19 of the head 4 is separated from the fixed portion 18 and the used toilet paper that has been gripped is released. Then, as an operation of dropping the toilet paper (step ST22), the control unit 54 rotates the second servo motor 36 by a predetermined amount (preferably at a high speed for a predetermined amount), thereby rotating the arm 6 and the head 4 about the axis N. And the upper surface 4a of the head 4 is directed downward. As a result, the toilet paper placed on the head 4 falls into the toilet bowl. The operation for dropping the toilet paper may be repeated twice or more.

  After the above wiping process is completed, the control unit 54 rotates the linear drive motor 48, the second servo motor 36, and the like by a predetermined amount to move the head 4 from the “wiping completed position” to the “cleaning position” ( Step ST23). Note that the “wiping completion position” and the “cleaning position” may coincide with each other, and in this case, this step is omitted.

  In step ST24, the control unit 54 drives the disinfecting liquid supply pump 85 to inject disinfecting liquid onto the head 4 at the “head cleaning position”. Thereby, the head 4 is cleaned and disinfected.

  In step ST25, the control unit 54 operates the blower 83 to dry the head 4 wet with the cleaning liquid.

  In step ST26, the control unit 54 rotates the third servo motor 38 by a predetermined amount so that the head 4 is detected by the filth detection sensor 86 in the interposition unit 3 (the position of the head 4 indicated by a two-dot chain line in FIG. 11). The sensor 86 confirms that no dirt has adhered to the head 4. If it is determined that dirt is attached to the head 4 (step ST26: NO), the head 4 is moved to the cleaning position (step ST23), and the processes of ST24 and ST25 are performed again. On the other hand, when it is determined that no filth is attached to the head 4 (step ST26: YES), a storage process for the head 4 and the arm 6 described later is executed (step ST27). Although various types of filth detection sensors 86 can be employed, in the present embodiment, a milky white and translucent material is employed for the head 4, and the filth detection sensors 86 are projected from the bottom to the top. The projector is composed of a projector composed of a light emitting LED and a light receiver that receives the projected light. Then, when the illuminance of light when the light emitted from the light projector is received by the light receiver via the head 4 is lower than a predetermined threshold value, it is determined that dirt is attached to the head 4.

  In step ST27, the control unit 54 drives the head entrance / exit opening / closing motor 26 to close the head entrance / exit 3a with the shutter 23. At the same time, the third servo motor 38 is rotated until the arm 6 faces substantially in the front-rear direction. Thereafter, the linear drive motor 48 is driven, the linear slider 45 is moved to the last position detected by the third limit switch 53, and the head 4 and the arm 6 are returned to the initial positions. Thereafter, the process is returned to step ST5, and when the wiping start switch 76 is turned on again, the above processing operation is repeatedly executed.

  As is clear from the above description, according to the automatic moisture wiping device 1 for the heel part according to the embodiment of the present invention, the head 4 that has grabbed the toilet paper passes through the passage 3b in the interposition part 3 and is excreted. When it is arranged at a predetermined value in the region, it rotates up a predetermined amount around the axis N and gets up. In other words, unlike the apparatus according to the conventional example, the moisture attached to the buttock can be wiped with the toilet paper grasped by the head 4 without moving the tip end side of the arm up and down. Therefore, it is not necessary to provide a large gap between the toilet seat and the toilet bowl as in the conventional apparatus.

  Further, according to the automatic moisture wiping device 1 for the heel portion according to the embodiment of the present invention, when the head 4 passes through a predetermined position in the interposition part 3, the eccentric direction of the head 4 becomes substantially horizontal. The vertical dimension of the portion corresponding to the predetermined position 3 can be reduced. In the present embodiment, the predetermined position is a position where the head 4 overlaps with the toilet seat 11 when viewed from above. In this case, the height from the upper surface of the toilet bowl 9 to the seat surface of the toilet seat 11 does not have to be so high. The effect of being finished is obtained.

  In addition, according to the automatic moisture wiping device 1 for the heel portion according to the embodiment of the present invention, the arm 6 has an axis line extending from the first arm part 6a provided on the axis line N and the tip end part of the first arm part 6a. A second arm portion 6b extending in a direction perpendicular to N, and the head 4 is provided at the tip of the second arm portion 6b, so that the size of the head 4 is increased. Therefore, the amount of rising of the head 4 can be increased.

  Moreover, since the interposition part 3 of the automatic moisture wiping device 1 for the heel according to the embodiment of the present invention is sandwiched between the toilet bowl 9 and the toilet seat unit 2, the present apparatus 1 is a general fixed installation type. Can be easily retrofitted to the toilet bowl 9.

  In addition, according to the automatic moisture wiping device 1 for the heel portion according to the embodiment of the present invention, since the head 4 passes through the interposition part 3, it becomes difficult for dirt to adhere to the toilet paper. That is, when the head holding the toilet paper passes through the gap between the toilet seat and the toilet bowl as in the device according to the conventional example, the dirt attached to the lower surface of the toilet seat or the upper surface of the toilet bowl may adhere to the moisture wiping material. Such a situation is unlikely to occur according to the present embodiment.

Based on input signals from the sensor 77, the remaining paper amount detection sensor 79, the nozzle detection sensor 81, the paper gripping detection sensor 82, the filth detection sensor 86, etc., the first to second servo motors 35 and 36, the linear drive motor 48, The head inlet / outlet opening / closing motor 26, the paper insertion servo motor 67, the automatic paper feeder 61, the announcement unit 74, the error lamp display unit 75, the blower 83, the disinfectant supply pump 85, and the like are driven and controlled or turned on / off.

  The paper attachment portion 8A is the same as the paper attachment portion 8 in the first embodiment. However, in this embodiment, the paper attachment portion 8A is installed behind the toilet seat unit 2.

  The head entrance / exit opening / closing device 15A opens / closes the head entrance / exit 3Aa formed over a predetermined range of the inner surface of the interposition part 3A, and as in the first embodiment, the shutter 23, the shutter feed device 24, the guide The unit 25 is configured. However, the position of the head entrance 3Aa that is opened and closed by the shutter 23 is slightly different from that of the first embodiment. That is, in the present embodiment, the arm 6 facing in the lateral direction moves back and forth, so that the head 4 moves between the excretion opening 14 and the rear position from the toilet seat 11. The head inlet / outlet 3Aa is formed so that the head 4 and the arm 6 that move to the right and left can be moved in and out.

  The head disinfection device 20 is the same as that in the first embodiment, but in this embodiment, the head disinfection device 20 is installed on the side of the paper mounting portion 8A (the side opposite to the device casing 17A).

  The toilet bowl 9A is of a portable type, and as shown in FIG. 17, a sewage feed blade 30 is installed in a drainage path extending rearward in the horizontal direction immediately after the drainage hole 16 of the toilet bowl 9A. The sewage feed blade 30 has a spiral blade portion 30 a provided around the shaft portion 30 b, and the shaft portion 30 b is rotated by an electric motor 39. When the sewage feed blade 30 rotates, the sewage flowing into the drain hole 16 is sent to the sewage drain tube 42 and discharged to a predetermined place through the tube 42.

  Next, the operation of the automatic moisture wiping device 1A for the buttocks will be described with reference to the flowcharts of FIGS. As an initial state before the start of the wiping operation, the arm 6 is stored in the apparatus casing 17A and the interposition part 3A so as to face in the lateral direction (width direction of the toilet bowl 9A), and the head 4 is in a state in which the paper gripping function is released. It is assumed that this is placed on the floor surface 64 of the automatic paper feeder 61 (hereinafter, this position is also referred to as “initial position”). Since ST1 to ST11 and ST13 are the same as those in the first embodiment, description thereof will be omitted, and description will be given starting with the other steps.

  After an affirmative determination in step ST11, in step ST12A, the control unit 54A moves the head 4 from the initial position to a position before the shutter 23. That is, the control unit 54A rotates the linear drive motor 48 so that the linear slider 45 located at the position shown by the solid line in FIG. 20 and the head 4 and the like mounted thereon are shown by the two-dot chain line in FIG. As shown, the head 4 is moved to a position before the head entrance 3Aa by moving forward to a position detected by the first limit switch 51A (the limit switch is not shown in FIG. 11).

  In step ST <b> 14, the control unit 54 </ b> A determines whether the head 4 is gripping the toilet paper based on the output signal of the paper grip detection sensor 82. If an affirmative determination is made in this step, the process proceeds to step ST15. If a negative determination is made, the announcement unit 74 announces a paper grip error (step ST16) and turns off the main power switch 72 (step ST4).

  In step ST15, the control unit 54A drives the head entrance / exit opening / closing motor 26 to slide the shutter 23 in the fully closed position in the opening direction, thereby opening the head entrance 3Aa.

  In step ST <b> 16, the control unit 54 </ b> A determines based on the output signal of the shutter opening / closing sensor 28 whether or not the head entrance 3 a is fully opened. If an affirmative determination is made here, the process proceeds to step ST17A. If a negative determination is made, the announcement unit 74 makes an announcement that the shutter has not opened (step ST18), and turns off the main power switch 72 (step ST18A). ST4).

  Next, in steps ST17A and ST19 to ST22, the control unit 54A executes a moisture wiping process for the heel.

  In step ST17A, the control unit 54A is mounted on the linear slider 45 by rotating the linear driving motor 48 from the state where the head 4 and the arm 6 are located at the position indicated by the two-dot chain line in FIG. The head 4 or the like is advanced to a position where the linear slider 52A is detected by the second limit switch 52A, and as shown in FIG. 21, the head 4 is moved to a “wiping operation start position” in the excretion opening 14 (in the excretion area). Move to. However, during the movement, when the head 4 passes through a position overlapping the toilet seat 11 as viewed from above, the head 4 is adjusted so that the eccentric direction of the head 4 with respect to the axis N is substantially horizontal. The rotational position of is maintained.

  In step ST19, the control unit 54A rotates the second servo motor 36 by a predetermined amount, thereby rotating the arm 6 by a predetermined amount around the axis N to raise the head 4 at the “wiping operation start position”.

  In step ST20, the control unit 54A rotates the linear drive motor 48 to move the linear slider 45 and the head 4 mounted on the linear slider 45 backward (that is, the eccentricity of the head 4 with respect to the axis N). While the head 4 is moved rearward in a state in which the direction forms an obtuse angle with respect to the traveling direction), the toilet paper held on the head 4 that has risen is wiped off the water adhering to the buttock. During this operation, the head 4 and the arm 6 move from the position shown in FIG. 21 to the position shown in FIG. 22 (position where the slider 45 is detected by the third limit switch 53A). The operation of the second servo motor 36 while the head 3 is moving backward is the same as in the first embodiment.

  In step ST <b> 21, the control unit 54 </ b> A rotates the first servo motor 35 by a predetermined amount to push the distal end side of the operation wire 21 from the arm 6. As a result, the occlusal portion 19 of the head 4 is separated from the fixed portion 18 and the toilet paper that has been gripped is released. Then, the control unit 54A performs the same operation as the operation described in the first embodiment, thereby dropping the toilet paper from the head 4 into the toilet bowl 9A (step ST22).

  After the above wiping process is completed, the control unit 54A rotates the linear drive motor 48 by a predetermined amount to move the head 4 from the wiping completion position to the cleaning position (step ST23A). Note that the wiping completion position and the cleaning position may coincide with each other, and in this case, this step is omitted.

  In step ST24, the controller 54A drives the disinfectant supply pump 85 to inject disinfectant onto the head 4 at the “head cleaning position”.

  In step ST25, the control unit 54A operates the blower 83 to dry the head 4 wet with the cleaning liquid.

  In step ST26, the control unit 54A and the linear drive motor 48 are rotated by a predetermined amount, and the head 4 is detected by the filth detection sensor 86 in the interposition unit 3A (position where the linear slider 54 is detected by the first limit switch 51A). The sensor 86 confirms that no dirt is attached to the head 4.
