Is positioned and held. Further, at this time, the shutter base 20 and the nozzle unit 11 are held in a connected state so that a large gap does not occur in their connection portions, that is, in a manner that their connection surfaces are in surface contact.

Next, the shutter 10 is detachably attached to both ends of the shaft 35 of the shutter arm 21 (the end of the arm 36) so that the front and back of the shutter receiver 22 face each other, and can freely turn around the axis O3. Engage and attach. When the shutter 10 is attached, it is hooked on the spring connection portion 36 a on the other end side (rear end side) of the arm portion 36 to connect the spring member to the base 6 a and the arm portion 36.

  As a result, the spring member exerts a force to urge the shutter arm 21 to the rear in the cover case 6, and each arm 36 is retracted and housed in the rear of the space of the arm insertion portion 24c and the arm holding portion 23b. The shaft portion 35 and the shutter receiver 22 are disposed close to the front surface of the shutter base 20, and the shutter 10 and the shutter receiver 22 are disposed close to each other such that the back surface thereof faces the front surface of the shutter base 20. Therefore, in this state, the shutter 10 directs the front surface to the inside of the toilet body 1 to close the nozzle opening 9.

  Further, in the present embodiment, the shutter 10 is formed to be horizontally long, and the hot air drying unit 12, the suction port 43 of the deodorizing unit 13 and the blowout ports 42 and 44 are simultaneously closed together with the nozzle opening 9. ing.

  Next, a method for cleaning the local area with the local cleaning device 4 after using the flush toilet A according to the present embodiment will be described.

  First, after use, for example, when the user remotely operates the anus washing button, the controller detects this and issues an operation command, and the motor and the pinion rotate in one direction and one of the local washing nozzles is an anus washing nozzle The cleaning nozzle 7 advances forward.

  At this time, as shown in FIG. 6, FIG. 8, FIG. 9, and FIG. 16, on the back surface of the shutter receiver 22, an inclined surface 40a gradually approaching the back surface as it goes downward toward the position facing one local cleaning nozzle 7. A first contact pivoting portion 40 is provided. Therefore, when one of the local cleaning nozzles 7 advances and the tip end abuts on the inclined surface 40a of the first abutment rotation unit 40, and further advances, the inclined surface 40a of the first abutment rotation unit 40 is pressed. As shown in FIGS. 7 and 19, the shutter receiver 22 pivots upward so that the back surface thereof is directed downward according to the shape of the first contact pivoting portion 40 (inclined surface 40a).

  Then, since the shutter 10 is superimposed on the shutter receiver 22, the shutter 10 is pressed and driven by the shutter receiver 22, and the shutter 10 is also pivoted upward so that the back surface thereof is directed downward.

  Further, as shown in FIG. 6, FIG. 8, FIG. 9, FIG. 13, FIG. 16, FIG. 20, a rib 38 is provided on the arm portion 36, and a rib 38 is formed on the arm holding portion 23b and the arm insertion portion 24c. By being guided by being engaged with the guide groove 33, the shutter arm 21 and thus the shutter receiver 22 and the shutter 10 are preferably advanced forward with the advancement of the one local cleaning nozzle 7.

  Then, one of the local cleaning nozzles 7 is further advanced, and the arc-shaped upper turning surface 37 a and the lower turning surface 37 b of the turning portion 37 of the arm portion 36 are the upper turning locking surface 31 of the shutter base 20. The arm portion 36 smoothly rotates around the rotation portion 37 so as to raise its tip end side.

  At this time, since the support projection 38a of the rib 38 is engaged with the guide groove 33, the arm 36 and hence the shutter receiver 22 and the shutter 10 do not fall when the arm 36 advances forward. Thereby, it advances while pressing the inclined surface 40a of the 1st contact | abutting rotation part 40 with the front-end | tip part of one local washing nozzle 7, and the upper rotation surface 37a of the rotation part 37 of the arm part 36, downward rotation The surface 37 b is in surface contact with the upper rotation locking surface 31 and the lower rotation locking surface 32 of the shutter base 20, so that the arm 36 can be smoothly rotated around the rotation section 37.

  That is, in the flush toilet A of the present embodiment, when one of the local washing nozzles 7 advances, the shutter 10 is automatically pivoted upward around the pivoting portion 37 together with the arm portion 36 and the back surface thereof The shutter receiver 22 pivots about the axis O3 of the shaft portion 35 of the shutter arm 21 so as to turn downward.

  Thus, the nozzle opening 9 is opened, and the hot water of the washing water can be discharged from the tip of the local washing nozzle 7 which has been advanced to the inside of the toilet body 1 by the driving of the hot water supply unit to wash the local . Further, at the time of this cleaning, the shutter 10 is disposed above the nozzle opening 9 and above one of the local cleaning nozzles 7 with the front surface facing upward. For this reason, dirt, splashes of washing water, and the like are blocked by the shutter 10, and the local washing nozzles 7, 8 and the nozzle opening 9 are prevented from getting into or entering inside thereof.

  When local washing is completed by one local washing nozzle 7, the motor and pinion rotate in the other direction automatically or by control according to the remote control operation of the user, etc., and one local washing nozzle which is an anus washing nozzle 7 retracts backward. Further, when one of the local cleaning nozzles 7 retracts backward, the arm portion 36 of the shutter arm 21 is urged rearward by the spring member, so that the shutter arm 21 automatically retracts backward.

  Furthermore, when one of the local cleaning nozzles 7 retracts and retracts backward, since the inclined portion 38b is provided on the rear end side of the rib 38 of the arm portion 36, this inclined portion 38b is preferably a guide groove Then, the shutter arm 21 is retracted rearward preferably. Then, one of the local cleaning nozzles 7 is accommodated in the cover case 6 through the nozzle opening 9, and the contact and pressing state of the first contact rotation unit 40 is released, and the shutter receiver 22, shutter together with the shutter arm 21 The 10 rotates while retracting backward. As a result, the shutter 10 closes the nozzle opening 9 and returns to the original state.

  On the other hand, for example, when the user remotely operates the bidet washing button, the control device detects this and issues an operation command, and the motor and pinion rotate in one direction and one local washing nozzle 7 which is an anus washing nozzle Advance to the front, and press the inclined surface 40a of the first contact rotation part 40 in the same manner as above to rotate the shutter receiver 22 and the shutter arm 21 upward while advancing the front, so that the back surface is directed downward. The shutter 10 is pivoted upward to open the nozzle opening 9.

  At the time of the bidet cleaning, one of the local cleaning nozzles 7 opens the shutter 10 and stops in a state of being disposed below the shutter 10 so that it does not advance inside the toilet body 1 any more.

  At the stage when the shutter 10 is opened by one local cleaning nozzle 7, the other local cleaning nozzle 8 which is a bidet cleaning nozzle advances forward, and advances to a predetermined position inside the toilet body 1 without contacting the shutter 10. Do. The hot water of the wash water is discharged from the tip of the other local washing nozzle 8 which has advanced to the inside of the toilet body 1 by the driving of the hot water supply unit, and the local can be washed. Further, at the time of this cleaning, the shutter 10 is disposed so as to cover the shutter 10 with the front surface directed upward, above the nozzle opening 9 and above the one local cleaning nozzle 7 and the other local cleaning nozzle 8. For this reason, the cleaning water, the dirt, the droplets of the cleaning water and the like are blocked by the shutter 10, and the local cleaning nozzles 7, 8 and the nozzle opening 9 and the inside thereof are prevented from being splashed or entering.

  When the local cleaning is completed by the other local cleaning nozzle 8, the motor and pinion rotate in the other direction automatically or by control according to the user's remote control operation, etc., and the other local cleaning nozzle is a bidet cleaning nozzle. 8 retracts backward and returns to the original position in the cover case 6 through the nozzle opening 9.

  At the same time, one of the local cleaning nozzles 7 is retracted backward. At this time, since the arm portion 36 of the shutter arm 21 is biased rearward by the spring member, the shutter arm 21 is automatically retracted rearward.

  Furthermore, when one of the local cleaning nozzles 7 retracts and retracts backward, since the inclined portion 38b is provided on the rear end side of the rib 38 of the arm portion 36, this inclined portion 38b is preferably a guide groove Then, the shutter arm 21 is retracted rearward preferably. Then, one of the local cleaning nozzles 7 is accommodated in the cover case 6 through the nozzle opening 9, and the contact and pressing state of the first contact rotation unit 40 is released, and the shutter receiver 22, shutter together with the shutter arm 21 The 10 rotates while retracting backward. As a result, the shutter 10 closes the nozzle opening 9 and returns to the original state.

  Next, an operation of attaching and detaching the shutter 10 of the flush toilet A according to the present embodiment to perform, for example, cleaning and maintenance will be described.

  In the flush toilet A of the present embodiment, when the shutter 10 is attached or detached, the user first presses the shutter attach / detach button (cleaning button) or the like, and when the control device detects this, the shutter at the shutter attach / detach In the attachment / detachment open mode, the controller issues an operation command to rotate the motor and pinion in one direction, and the other local cleaning nozzle 8 which is a bidet cleaning nozzle advances forward.

  At this time, at a position facing the other local cleaning nozzle 8, a second contact rotation portion 41 of the shutter receiver 22 provided with a reverse inclined surface 41a which is gradually separated from the rear surface as it goes downward is provided. Therefore, as shown in FIG. 6 and FIG. 9, when the other local cleaning nozzle 8 advances and the tip end abuts on the reverse inclined surface 41a of the second contact turning portion 41, and further advances, the second contact is made. The reverse inclined surface 41a of the contact rotation portion 41 is pressed, and the shutter receiver 22 and, consequently, the shutter 10 rotate downward so that the inner surface thereof is directed upward.

  Also, as shown in FIG. 6, FIG. 8, FIG. 9, FIG. 13, and FIG. 16, a rib 38 is provided on the arm portion 36, and this rib 38 is a guide groove formed in the arm holding portion 23b and the arm insertion portion 24c. By being guided by being engaged with 33, the shutter arm 21 and thus the shutter 10 is preferably advanced forward as the other local cleaning nozzle 8 is advanced. Furthermore, when the other local cleaning nozzle 8 advances further while pressing the reverse inclined surface 41a of the second contact rotating portion 41, the upper rotating surface 37a of the circular arc surface of the rotating portion 37 of the arm portion 36, lower The pivoting surface 37b is in surface contact with the upper pivoting locking surface 31 and the lower pivoting locking surface 32 of the shutter base 20, and the rib 38 gradually falls out of the guide groove 33 along the inclined portion 38b and drops The portion 36 smoothly rotates around the rotation portion 37 so as to lower its tip end side.

As a result, when the other local cleaning nozzle 8 advances, the arm 36 automatically advances, and the shutter 10 assumes an open posture in which the nozzle opening 9 is opened. Furthermore, when the other local cleaning nozzle 8 advances, the arm 36 pivots downward around the pivot 37, and the shutter 10 turns around the axis O3 of the shaft 35 of the shutter arm 21 so that its back surface is directed upward. The nozzle holder 9 is pivoted together with the shutter receiver 22, and the nozzle opening 9 is further opened.
The shutter arm 21 does not advance further in a state in which the shutter 10 is in the open position by the rotation portion 37 coming into contact with the upper rotation locking surface 31 and the lower rotation locking surface 32 of the shutter base 20 ( Can not).

  At this time, since the rotation receiving portion 22c is provided on the shutter receiver 22 so as to protrude in the lateral direction T1 from the side end, the rotation receiving portion 22c abuts on the arm portion 36 from the lower side. In turn, the rotation of the shutter 10 is restricted, and the shutter 10 (shutter receiver 22) is held in an open position with the back surface directed upward.

In this embodiment, the user presses the shutter attachment / detachment button in this manner, and the other local cleaning nozzle 8 is advanced, and the shutter 10 is pivoted downward so that the back surface is automatically directed upward. Open. Therefore, mounting portions (mounting positions) where the shutter 10 is connected to both end sides of the shaft portion 35 of the shutter arm 21 are exposed.

  As a result, when the user removes the shutter 10, the shutter 10 can be removed by, for example, pulling downward with both ends of the shutter 10 while visually checking the mounting position of the shutter 10.

  When the shutter 10 is removed, the movement of the shutter 10 in the direction in which the removal force acts is restricted. That is, the shutter arm 21 which has advanced is in a state where it can not advance any further, and is held in a state where it can not turn downward (a play may be made to turn downward about 5 degrees). Therefore, the shutter 10 can be removed appropriately (for example, easily with a small force) without being shaken when a force is applied to the shutter 10.

  Also, when the shutter 10 is attached, the shutter 10 can be attached by engaging while visually checking the attachment position of the shutter 10.

  Then, at the stage where the attachment / detachment, cleaning, maintenance and the like of the shutter 10 are completed, the motor and pinion rotate in the other direction by the control according to the user's remote control operation etc. 8 retracts backward and returns to the original position in the cover case 6 through the nozzle opening 9.

  At this time, since the inclined portion 38b is provided on the rear end side of the rib 38 of the arm portion 36, the inclined portion 38b is preferably reengaged with the guide groove 33 even if the arm portion 36 is retracted in a lowered state. The arm portion 36 is gradually lifted by the inclined portion 38b and the shutter arm 21 is suitably retracted backward. Then, the other local cleaning nozzle 8 is accommodated in the cover case 6 through the nozzle opening 9, and the contact / pressing state of the second contact rotation portion 41 is released, and the shutter receiver 22 and the shutter together with the shutter arm 21 The 10 rotates while retracting backward. As a result, the shutter 10 closes the nozzle opening 9 and returns to the original state.

  Therefore, in the local cleaning device 4 of the present embodiment, the shutter 10 is attached forwardly and reversely rotatably to the shutter arm 21 supported so as to be movable back and forth in the forward and backward direction T2 to advance the shutter 10 forward. The shutter 10 can be spaced forward from the nozzle opening 9 to open the nozzle opening 9. Further, together with this, the shutter receiver 22 and the shutter 10 can be rotated forward and reverse around the axis O3 of the shaft portion 35 extending in the lateral direction T1, and the shutter 10 can be rotated upward and downward relative to the nozzle opening 9 And the nozzle opening 9 can be opened.

  Furthermore, by attaching the shutter receiver 22 to the shaft portion 35 of the shutter arm 21 so as to be capable of rotating in the forward and reverse directions and providing the shutter 10 on the front side of the shutter receiver 22, the shutter is removed even when the shutter 10 is removed. The nozzle opening 9 can be closed by means of a receptacle 22 and the local cleaning nozzles 7, 8 can also be coated. As a result, even if the local cleaning nozzles 7 and 8 are operated without the shutter 10 for maintenance etc., compared to the conventional case, dirt or droplets of cleaning water may fall on the local cleaning nozzles 7 or 8. And can be prevented from entering from the nozzle opening 9.

  Further, the shutter 10 can be positively rotated above the nozzle opening 9 so that the back surface is directed downward by advancing the one local cleaning nozzle 7 and pressing the first contact rotation portion 40. Further, by causing the other local cleaning nozzle 8 to advance and pressing the second contact rotation portion 41, the shutter 10 can be rotated forward to the lower side of the nozzle opening 9 so that the back surface faces upward. Thus, the shutter 10 can be moved upward and downward in any direction only by controlling the advancing operation of the one local cleaning nozzle (one shutter operating unit) 7 and the other local cleaning nozzle (the other shutter operating unit) 8. It is possible to freely turn and open the nozzle opening 9. Therefore, maintenance such as cleaning and attachment / detachment operation of the shutter 10 can be performed more easily.

  Furthermore, by providing a rib 38 projecting downward in the arm portion 36 and extending in the longitudinal direction T2, when the arm portion 36 advances forward in the longitudinal direction T2, the axis O4 direction of the arm portion 36 is held constant and downward The arm portion 36 can be stably advanced without falling into the Thereby, for example, when the shutter 10 is rotated above the nozzle opening 9 to be opened, it is possible to smoothly shift from the forward movement operation to the upward rotation movement.

  Further, by providing the support projection 38a extending to the rear end side with the rib 38 having a constant projection length from the front end, the arm portion 36 advances forward in the front-rear direction T2 while the support projection 38a abuts on the lower surface. As a result, the direction of the axis O4 of the arm portion 36 can be reliably held constant, and the arm portion 36 can be stably advanced without falling downward.

  Furthermore, when retracting the arm portion 36 in the front-rear direction T2, even if the arm portion 36 falls downward, the arm portion 36 abuts the lower surface from the inclined portion 38b and lifts the arm portion 36 gradually, At the stage where the lower surface 38a abuts on the lower surface, the arm portion 36 can be retracted in a state in which the axis O4 direction is held constant. Thereby, for example, when closing the shutter 10 from the opened state by rotating the shutter 10 below the nozzle opening 9, the arm 36 is retracted smoothly and the nozzle opening 9 is closed by the shutter 10. Becomes possible.

  That is, by providing the rib 38 in the arm portion 36, the shutter 10 can be smoothly opened and closed.

  Further, for example, the shutter 10 is detachably attached to the shutter arm 21 by holding the shutter 10 in a state in which the shutter 10 is rotated below the nozzle opening 9 so that the back surface of the shutter 10 faces upward. The mounting portion can be easily visually checked from the top. As a result, the shutter 10 can be easily removed, and maintenance such as cleaning and attachment / detachment operation of the shutter 10 can be more easily performed as compared with the conventional case where the shutter is pivoted upward only in one direction. It will be possible.

  Furthermore, at the rear end side of the arm portion 36 of the shutter arm 21, the arm portion 36 is provided with a pivoting portion 37 which is advanced forward and locked and supported so as to be capable of rotating in the forward and reverse directions. It is possible to open the nozzle opening 9 by smoothly and largely rotating the shutter receiver 22 and thus the shutter 10 in the upper and lower directions respectively by rotating the portion 36 forward and reverse around the rotation portion 37. become.
