That is, since the rib 38 is engaged with the guide groove 33, the arm portion 36 is not inclined downward due to its own weight such as the shutter arm 21, and the like in the space of the arm holding portion 23b and the arm insertion portion 24c. It can be held freely.

  Here, the rib 38 of the present embodiment is formed on the rear end side with an inclined portion (R-shaped portion) 38b whose protruding length becomes smaller toward the rear end. Thereby, when the arm part 36 advances forward and only the inclined part 38b is engaged with the guide groove 33, the arm part 36 advances forward and the arm part 36 is inclined downward. When the inclined portion 38b moves further forward and comes out of the guide groove 33, the upper rotation locking surface 31, the lower rotation locking surface 32, the upper rotation surface 37a, and the lower rotation surface 37b come into surface contact. Each arm 36 is held so as to be rotatable in the vertical direction T3.

  Next, at the stage where the first base 23 and the second base 24 are assembled and the shutter base 20 and the shutter arm 21 are connected as described above, the shaft portion 35 of the shutter arm 21 is fitted into the rotary shaft fitting portion 22a. The engaging pieces 22b and 35a are respectively engaged, and the shutter receiver 22 is detachably attached to the shaft portion 35 of the shutter arm 21. Further, the shutter receiver 22 is attached to a predetermined position of the shaft portion 35 of the shutter arm 21 by the locking pieces 22b and 35a, and the rotation restricting portion 22c protruding from the side end portion of the shutter receiver 22 in the lateral direction T1 is the shutter arm 21. The arm portion 36 is arranged at a position overlapping the vertical direction T3.

  As a result, as shown in FIGS. 8, 9, 13, 14, 15, and 16, the shutter receiver 22 is rotatably disposed around the axis O3 of the shaft portion 35 of the shutter arm 21. . In addition, the rotation restricting portion 22c abuts on the arm portion 36 at the time of turning, and the rotation range (rotation amount) is restricted so that the back surface does not face forward.

  Here, by forming the shutter receiver 22 (and the shutter arm 21 (shaft portion 35)) using a polyethylene resin or the like, wear or abnormal noise occurs when the local cleaning nozzles 7 and 8, which will be described later, come into contact with each other or rotate. Can be prevented from occurring.

  Next, as shown in FIGS. 6, 17, and 18, the fitting portion 25 of the main body portion 23 a of the first base 23 of the shutter base 20 is fitted to the nozzle cover 15, and the first base of the shutter base 20 is placed. The projections of the nozzle cover 15 are engaged between the pair of engagement projections 26 of the body 23a of the main body 23, and the shutter unit 17 (shutter base 20, shutter arm 21, shutter receiver 22) is opened in the nozzle opening of the base 6a. Installed in part 9.

  When the shutter unit 17 is installed in the nozzle opening 9 of the base 6a, the female screw hole 29 provided on the upper end side of the arm insertion portion 24c of the second base 24 and the screw insertion hole of the base of the cover case 6 communicate with each other. To do. By fastening the screw 30 to the female screw hole 29 through the screw insertion hole, the shutter unit 17 is fixed at a predetermined position of the base 6a.

  When the shutter unit 17 is fixed at a predetermined position on the base 6a, the nozzle cover 15 (nozzle unit 11) fitted and engaged with the shutter base 20 is moved to a predetermined position by the shutter unit 17. 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 at the connecting portion, that is, the connecting surfaces are in surface contact with each other.

  Next, the shutter 10 is detachably attached to both end sides of the shaft portion 35 of the shutter arm 36 (front end side of the arm portion 36) and is rotatable about the axis O3 so that the front surface and the back surface of the shutter receiver 22 face each other. Engage and attach. At the stage of attaching the shutter 10, the spring member is connected to the base 6 a and the arm portion 36 by being hooked on the spring connecting portion 36 a on the other end side (rear end side) of the arm portion 36.

  As a result, a force for urging the shutter arm 21 rearward in the cover case 6 acts by the spring member, and each arm portion 36 is retracted and accommodated rearward in 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 is disposed close to the shutter base 22 so that the back surface thereof faces the front surface of the shutter base 20. Therefore, in this state, the shutter 10 directs the front face to the inside of the toilet body 1 and closes the nozzle opening 9.

  In the present embodiment, the shutter 10 is formed in a horizontally long shape, and the nozzle opening 9 and the hot air drying unit 12, the suction port 43 of the deodorizing unit 13, and the outlets 42 and 44 are simultaneously closed. ing.

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

  First, after the toilet, for example, when the user remotely operates the anus cleaning button, the control device detects this and issues an operation command, and the motor and pinion rotate in one direction, and one local area that is an anal cleaning nozzle The cleaning nozzle 7 advances forward.

  At this time, as shown in FIGS. 6, 8, 9, and 16, the back surface of the shutter receiver 22 has an inclined surface 40 a that gradually approaches the back surface toward the position facing the one local cleaning nozzle 7. A first abutting rotation part 40 provided is provided. For this reason, when one of the local cleaning nozzles 7 moves forward and the tip comes into contact with the inclined surface 40a of the first contact rotation unit 40, and further advances, the inclined surface 40a of the first contact rotation unit 40 is pressed. As shown in FIGS. 7 and 19, the shutter receiver 22 rotates upward so that the back surface thereof faces downward according to the shape of the first abutting rotation portion 40 (inclined surface 40a).

  Since the shutter 10 is provided so as to overlap the shutter receiver 22, the shutter 10 is pressed and driven by the shutter receiver 22, and the shutter 10 also rotates upward so that the back surface thereof faces downward.

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

  Then, one of the local cleaning nozzles 7 further advances, and the upper rotation surface 37 a and the lower rotation surface 37 b of the arc-shaped surface of the rotation portion 37 of the arm portion 36 are the upper rotation locking surface 31 of the shutter base 20. The arm portion 36 smoothly rotates around the rotation portion 37 so as to come into surface contact with the lower rotation engagement surface 32 and to raise the tip end side thereof.

  At this time, the support protrusions 38a of the ribs 38 are engaged with the guide grooves 33, so that the arm portions 36, that is, the shutter receiver 22 and the shutter 10 are not lowered when the arm portions 36 advance forward. Accordingly, the inclined surface 40a of the first abutting rotation part 40 is advanced while being pressed by the tip part of one of the local cleaning nozzles 7, and the upper rotation surface 37a of the rotation part 37 of the arm part 36 is rotated downward. The surface 37 b comes into surface contact with the upper rotation locking surface 31 and the lower rotation locking surface 32 of the shutter base 20, and the arm portion 36 can be smoothly rotated around the rotation portion 37 reliably.

  That is, in the flush toilet A of the present embodiment, when one of the local washing nozzles 7 moves forward, the shutter 10 automatically rotates together with the arm portion 36 around the rotation portion 37, and the back surface thereof is It rotates together with the shutter receiver 22 around the axis O3 of the shaft portion 35 of the shutter arm 21 so as to face downward.

  In this way, the nozzle opening 9 is opened, and the hot water of the cleaning water is discharged by driving the hot water supply unit from the tip of one of the local cleaning nozzles 7 that has advanced to the inside of the toilet body 1, and the local portion can be cleaned. . 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 so that the shutter 10 covers the front surface. For this reason, filth, splashes of washing water, etc. are blocked by the shutter 10, and the local washing nozzles 7 and 8 and the nozzle opening 9 and the inside thereof are prevented from entering or entering.

  When the local cleaning is completed by one of the local cleaning nozzles 7, the motor and the pinion rotate in the other direction automatically or by control according to the user's remote control operation. 7 retracts backward. When one of the local cleaning nozzles 7 is retracted backward, the shutter arm 21 is automatically retracted backward because the arm portion 36 of the shutter arm 21 is biased backward by the spring member.

  Further, when one of the local cleaning nozzles 7 is retracted and retracted backward, an inclined portion 38b is provided on the rear end side of the rib 38 of the arm portion 36. Therefore, the inclined portion 38b is preferably used as a guide groove. 33 is re-engaged, and the shutter arm 21 is preferably retracted rearward. Then, one of the local cleaning nozzles 7 is accommodated in the cover case 6 through the nozzle opening 9, the contact and pressing state of the first contact rotation unit 40 is released, and together with the shutter arm 21, the shutter receiver 22, the shutter 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 operates the bidet cleaning button by remote control, the control device detects this and issues an operation command, and the motor and pinion rotate in one direction, so that one of the local cleaning nozzles 7 serving as an anal cleaning nozzle Advance forward, press the inclined surface 40a of the first abutting rotation portion 40 in the same manner as described above, rotate the shutter receiver 22 and the shutter arm 21 forward, and rotate upward, so that the back faces downward. The nozzle opening 9 is opened by rotating the shutter 10 upward.

  During this bidet cleaning, one of the local cleaning nozzles 7 opens the shutter 10 and stops in a state of being arranged below the shutter 10 so that it does not advance further into the toilet body 1.

  When the shutter 10 is opened by one local washing nozzle 7, the other local washing nozzle 8, which is a bidet washing nozzle, advances forward and advances to a predetermined position inside the toilet body 1 without contacting the shutter 10. To do. The warm water of the washing water is discharged by driving the hot water supply unit from the tip of the other local washing nozzle 8 that has advanced to the inside of the toilet body 1 so that the local portion can be washed. Further, at the time of this cleaning, the shutter 10 is disposed above the nozzle opening 9 and above the one local cleaning nozzle 7 and the other local cleaning nozzle 8 so that the front surface is directed upward. For this reason, washing water, filth, splashes of washing water, etc. are blocked by the shutter 10, so that the local washing nozzles 7 and 8 and the nozzle opening 9 and the inside thereof are prevented from splashing and entering.

  When the local cleaning by the other local cleaning nozzle 8 is completed, the other local cleaning nozzle which is a bidet cleaning nozzle by rotating the motor and pinion in the other direction automatically or by control according to the remote control operation of the user. 8 retreats 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 retracts backward. At this time, since the arm portion 36 of the shutter arm 21 is biased backward by the spring member, the shutter arm 21 automatically retracts backward.

  Further, when one of the local cleaning nozzles 7 is retracted and retracted backward, an inclined portion 38b is provided on the rear end side of the rib 38 of the arm portion 36. Therefore, the inclined portion 38b is preferably used as a guide groove. 33 is re-engaged, and the shutter arm 21 is preferably retracted rearward. Then, one of the local cleaning nozzles 7 is accommodated in the cover case 6 through the nozzle opening 9, the contact and pressing state of the first contact rotation unit 40 is released, and together with the shutter arm 21, the shutter receiver 22, the shutter 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 for attaching and detaching the shutter 10 of the flush toilet A of the present embodiment, for example, for cleaning and maintenance will be described.

  In the flush toilet A of the present embodiment, when the shutter 10 is attached / detached, the user first presses the shutter attaching / detaching button (cleaning button), and when this is detected by the control device, the shutter when the shutter is attached / detached. The attachment / detachment opening mode is entered, the control device issues an operation command, the motor and the pinion rotate in one direction, and the other local washing nozzle 8 which is a bidet washing nozzle advances forward.

  At this time, the second abutting rotation portion 41 of the shutter receiver 22 is provided at a position facing the other local cleaning nozzle 8 and provided with a reverse inclined surface 41a gradually moving away from the back surface as it goes downward. For this reason, as shown in FIGS. 6 and 9, when the other local cleaning nozzle 8 moves forward and the tip end comes into contact with the reverse inclined surface 41a of the second contact rotating part 41, and further advances, The reverse inclined surface 41a of the contact rotating part 41 is pressed, and the shutter receiver 22, and consequently the shutter 10, rotates downward so that the inner surface thereof faces upward.

  As shown in FIGS. 6, 8, 9, 13, and 16, the arm portion 36 is provided with a rib 38, and the rib 38 is formed in the arm holding portion 23b and the arm insertion portion 24c. By being engaged with and guided by 33, the shutter arm 21 and thus the shutter 10 are preferably advanced forward as the other local cleaning nozzle 8 is advanced. Further, when the other local cleaning nozzle 8 further advances while pressing the reverse inclined surface 41a of the second abutting rotation part 41, the arcuate surface-like upper rotation surface 37a of the rotation part 37 of the arm part 36, the lower part The rotation surface 37b comes into surface contact with the upper rotation engagement surface 31 and the lower rotation engagement surface 32 of the shutter base 20, and the rib 38 gradually falls off the guide groove 33 along the inclined portion 38b and falls. The part 36 smoothly rotates around the rotating part 37 so as to lower the tip side.

As a result, when the other local cleaning nozzle 8 advances, the arm portion 36 automatically advances and the shutter 10 assumes an open posture in which the nozzle opening 9 is opened. Further, when the other local cleaning nozzle 8 advances, the arm portion 36 rotates downward around the rotation portion 37 and the shutter 10 faces the axis O3 of the shaft portion 35 of the shutter arm 21 so that the back surface thereof faces upward. Then, it is rotated together with the shutter receiver 22 so that the nozzle opening 9 is further opened.
Note that the shutter arm 21 does not advance any further in a state in which the shutter 10 is in the open position by the rotation portion 37 contacting the upper rotation locking surface 31 and the lower rotation locking surface 32 of the shutter base 20 ( Can not).

  At this time, the shutter receiver 22 is provided with the rotation restricting portion 22c that protrudes in the lateral direction T1 from the side end portion, so that the rotation restricting portion 22c comes into contact with the arm portion 36 from the lower side, thereby Thus, the rotation of the shutter 10 is restricted, and the shutter 10 (shutter receiver 22) is held in an open posture with the back face upward.

  In the present embodiment, the user presses the shutter attaching / detaching button as described above, and the other local cleaning nozzle 8 moves forward, so that the shutter 10 is rotated downward so that the back surface is automatically directed upward. Open. For this reason, the attachment part (attachment position) which connected the shutter 10 to the both ends of the shaft part 22a of the shutter arm 21 is exposed.

  Thus, when the user removes the shutter 10, the user can remove the shutter 10 by pulling down the both ends of the shutter 10 while visually confirming the mounting position of the shutter 10.

  Further, 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 advanced shutter arm 21 is held in a state where it can no longer move forward and in a state where it cannot rotate downward (there may be a play that rotates about 5 degrees downward). For this reason, when a force is applied to the shutter 10, the shutter 10 can be suitably removed (for example, easily with a small force).

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

  Then, when the attachment / detachment / cleaning / maintenance of the shutter 10 is completed, the other local cleaning nozzle, which is a bidet cleaning nozzle, is rotated by the motor and pinion in the other direction by the control according to the user's remote control operation. 8 retreats backward and returns to the original position in the cover case 6 through the nozzle opening 9.

  At this time, since the inclined portion 38 b is provided on the rear end side of the rib 38 of the arm portion 36, the inclined portion 38 b is preferably re-engaged with the guide groove 33 even if the arm portion 36 is retracted. At the same time, the arm portion 36 is gradually lifted by the inclined portion 38b, and the shutter arm 21 is preferably retracted rearward. Then, the other local cleaning nozzle 8 is accommodated in the cover case 6 through the nozzle opening 9, and the abutting and pressing state of the second abutting rotation part 41 is released, and together with the shutter arm 21, the shutter receiver 22, the shutter 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 flush toilet A and the local washing apparatus 4 of the present embodiment, a shutter opening / closing mechanism (shutter unit) that can hold / hold the shutter 10 in an open position in which the nozzle opening 9 is opened when the shutter 10 is attached / detached. 17), the attachment / detachment operation (detachment operation) of the shutter 10 can be performed while visually confirming the position of the attachment portion where the shutter 10 is detachably attached.

  Thereby, compared with the past, the operability of the attaching / detaching operation of the shutter 10 is good and can be performed easily and smoothly. In addition, since the mounting portion can be seen, it is possible to prevent damage due to incorrect assembly or excessive pushing.

Further, in the flush toilet A and the local washing apparatus 4 of the present embodiment, when the shutter 10 is attached and detached, the shutter 10 is rotated to the lower side of the nozzle opening 9 so that the back surface of the shutter 10 faces upward. By holding the shutter 10 in the open posture, the mounting portion of the shutter 10 can be easily visually confirmed from above.
This makes it possible to more easily perform the attaching / detaching operation (detaching operation) of the shutter 10.

Further, when the shutter 10 is attached / detached, the other local cleaning nozzle 8 is advanced, and the shutter 10 is pressed and opened, and is stopped in contact with the shutter 10 so that the shutter 10 is held in an open posture. Thus, for example, it is possible to hold the shutter 10 in an open posture when the shutter 10 is attached / detached without adding a special mechanism only by adding operation control when the shutter 10 is attached / detached.
As a result, it is possible to easily and economically improve the attaching / detaching operation of the shutter 10.

Further, since the shutter 10 is configured to be rotatably and detachably attached to the shutter arm 21 supported so as to be able to advance and retreat in the front-rear direction T2, the shutter arm 21 (arm portion 36) is moved forward when the shutter 10 is attached / detached. The shaft portion 35 and thus the mounting portion of the shutter 10 can be separated from the shutter opening 9.
Thereby, the attachment part of the shutter 10 can be visually confirmed more reliably and easily, and it becomes possible to aim at the further workability | operativity at the time of attachment or detachment of the shutter 10.

  Further, when the shutter 10 is removed, the movement of the shutter 10 in the direction in which the removal force acts is restricted, and the advanced shutter arm 21 is held in a state where it cannot be advanced any further and cannot be rotated downward. When a force is applied to the shutter 10, the shutter 10 can be suitably removed without wobbling.

  As mentioned above, although one Embodiment of the local cleaning apparatus which concerns on this invention was described, this invention is not limited to said one Embodiment, In the range which does not deviate from the meaning, it can change suitably.
