When the tank cover 50 is put on the washing water tank 30, the washing water tank 30 is arranged on the upper part of the base plate 20 as shown in FIG.
In this state, the tank cover 50 is put on the washing water tank 30 so as to cover the washing water tank 30, and the lower end of the tank cover 50 is attached to the base plate 20.
Then, the spout fixing portion 43 is attached to the spout attaching hole 41 a of the hand washing bowl portion 41, and the hand washing spout 42 is attached to the spout fixing portion 43. After that, the hand-washing water discharge pipe 42 is fixed to the water discharge pipe fixing part 43 by using the water discharge pipe clip 44. Further, on one side of the tank cover 50, a cleaning operation lever handle 81 is attached to the cleaning operation section 82 from outside the tank cover 50.
In this way, as shown in FIG. 1, the tank cover 50 is put on the washing water tank 30 so as to cover the washing water tank 30.

Next, details of the flow operation mechanism 70 as the operation mechanism of the present invention will be described with reference to the drawings.
The flow operation mechanism 70 operates a water flow adjustment mechanism (not shown) for adjusting the flow of water flowing through a water supply flow path (not shown) of the wash water supplied from the water supply unit 60 (see FIG. 2). .
The water flow adjusting mechanism (not shown) is provided in a water supply flow path (not shown) that supplies cleaning water from the water supply unit 60 (see FIG. 2) to the cleaning water tank 30.

  As shown in FIGS. 3 to 5, the flow operation mechanism 70 includes an operation dial section 71 as an operation section, an operation main body section 72, and an operation cable 73 as a connection cable.

  The operation cable 73 connects the water flow adjusting mechanism (not shown) and the operation dial unit 71. When the operation dial portion 71 is operated, the operation cable 73 moves the internal cable 73a (see FIG. 4) disposed therein, and the flow valve (not shown) of the flow adjustment mechanism (not shown). Is moved to the closed state or the open state. By operating the operation dial unit 71 to open the flow valve (not shown), the flow is maintained even when the water supply unit 60 (see FIG. 2) stops the washing water in the washing water tank 30. A small amount of water can be circulated through the valve. Thereby, for example, a small amount of water can be continuously circulated in an area where there is a risk of freezing of the water supply part in winter, such as a cold region, so that the water supply part 60 can be prevented from freezing.

  As shown in FIGS. 4 and 5, an operation dial 71 is attached to the operation main body 72. The operation dial 71 attached to the operation main body 72 is attached to the operation dial attachment 21 of the base plate 20 via the operation main body 72. The operation dial mounting portion 21 of the base plate 20 is disposed on one end side of the base plate 20 in the left-right direction.

  The operation main body 72 is formed in a tubular shape, and has a base end side tube part 721, a terminal end side tube part 722, and a flange part 723. The proximal-side tubular portion 721 and the terminal-side tubular portion 722 are formed linearly and continuously, and communicate with each other.

As shown in FIG. 4, the proximal-side cylindrical portion 721 has a proximal-side opening 721a at a proximal-side end.
The operation cable 73 is inserted into the proximal opening 721a. One end of the operation cable 73 is connected to a water flow adjusting mechanism (not shown), and the other end of the operation cable 73 is connected to the operation dial unit 71.

As shown in FIG. 4, the end-side cylindrical portion 722 has an end-side opening 722 a at an end on the end side.
The operation dial section 71 is arranged on the end side cylinder section 722. The operation dial portion 71 is rotatably attached to the terminal side opening 722a.

  The flange portion 723 is formed so as to extend along the circumferential direction on a peripheral surface substantially at the center in the vertical direction of the operation main body portion 72 (boundary between the proximal-side cylindrical portion 721 and the terminal-side cylindrical portion 722).

  The operation dial portion 71 is attached to the operation dial attachment portion 21 of the base plate 20 while being attached to the operation main body portion 72. The operation dial unit 71 is attached to the operation dial attachment unit 21 of the base plate 20 via the operation main unit 72 so as to be located below the base plate 20.

  By rotating and operating the operation dial unit 71, the operation cable 73 is moved, and the flow valve (not shown) is moved between the closed state and the open state. Thereby, it can be operated between a state in which a small amount of water flows through the flow valve and a state in which water does not flow.

  As shown in FIGS. 3 to 5, the operation dial mounting portion 21 is disposed in a partition portion 22 of the base plate 20 that is separated from a portion (tank placement portion) 23 where the washing water tank 30 is disposed. The partition section 22 partitions the operation dial mounting section 21 and the tank arrangement section 23. The partitioning section 22 partitions the operation dial mounting section 21 from a portion of the base plate 20 where water accumulates.

For example, the partition part 22 is formed at a position that does not overlap with the washing water tank 30 arranged on the base plate 20 in plan view (when viewed in the vertical direction). Therefore, even if the water droplets attached to the outer surface of the cleaning water tank 30 drop on the base plate 20 along the surface of the cleaning water tank 30, the partitioning portion 22 is formed at a position where water intrusion is suppressed.
Further, for example, the partition part 22 has a peripheral wall part 221. The peripheral wall portion 221 is formed to rise from the bottom surface 20 a of the base plate 20 so as to surround the operation dial mounting portion 21. By having the peripheral wall portion 221, it is possible to prevent the water accumulated on the bottom surface 20 a of the base plate 20 from entering the partition portion 22. The partition 22 is not limited to surrounding the operation dial attachment 21. For example, the partition part 22 may be a wall part disposed between the operation dial mounting part 21 and the tank placement part 23, and may be a wall part that does not surround the operation dial mounting part 21.

As shown in FIGS. 3 to 5, the operation dial mounting portion 21 is arranged inside the peripheral wall portion 221 of the partition portion 22.
The operation dial mounting portion 21 has a plate-shaped substrate portion 211, a substantially C-shaped frame wall 212, and a mounting piece 213.

The substrate portion 211 is formed in a plate shape, and is formed above the bottom surface 20 a of the base plate 20 and substantially parallel to the bottom surface 20 a of the base plate 20.
In the substrate portion 211, an elongated hole opening 21a and a groove-shaped opening 21b formed continuously with the elongated hole opening 21a are formed.

The long hole opening 21a is a through hole extending in a predetermined direction, and is formed to have a size that allows the operation dial portion 71 attached to the operation main body portion 72 to be inserted. When the operation dial 71 attached to the operation main body 72 is inserted into the elongated hole 21a, the operation dial 71 can be moved in the length direction of the elongated hole 21a (the direction in which the elongated hole 21a extends). It is formed in size.
Further, the elongated hole opening 21a is formed in a size that does not allow the flange portion 723 of the operation main body 72 to be inserted. When the operation dial portion 71 attached to the operation main body portion 72 is inserted into the long hole opening 21a from the upper surface side of the substrate portion 211, the flange portion 723 of the operation body portion 72 inserted into the long hole opening 21a It contacts the upper surface of the part 211.
A mounting piece 213 to be described later is arranged in the groove-shaped opening 21b.

  The frame wall 212 is formed along the upper surface of the substrate portion 211 in a substantially C-shape with one side opened in a horizontal direction in plan view. The frame wall 212 is formed along the elongated hole opening 21a at a position outside the elongated hole opening 21a at a predetermined distance on the upper surface of the substrate portion 211, and protrudes upward from the upper surface of the substrate portion 211.

  As shown in FIG. 5, the frame wall 212 has an upper side movement restricting portion 212a. The upper side movement restricting portion 212a is formed on a portion of the frame wall 212 opposite to the mounting piece 213. The upper side movement restricting portion 212a extends toward the inside of the frame wall 212 above the frame wall 212 with a gap 212b formed between the upper side movement restricting portion 212a and the substrate portion 211. In the gap 212b of the frame wall 212, when the operation dial 71 attached to the operation main body 72 is inserted into the elongated hole opening 21a and the flange 723 is in contact with the upper surface of the substrate 211, the operation main body 72 is By sliding the attached operation dial portion 71 along the elongated hole opening 21a to the side opposite to the open side of the frame wall 212, a part of the flange portion 723 of the operation main body portion 72 is accommodated. Thus, the upward movement of the flange portion 723 of the operation main body 72 is restricted by the upward movement restriction portion 212a of the frame wall 212.

  The mounting piece 213 is disposed in the groove-shaped opening 21b. The mounting piece 213 is formed in a plate shape parallel to the board portion 211. The mounting piece 213 is configured to be elastically deformable.

  One end of the mounting piece 213 is fixed to the peripheral wall 221 of the partition 22 on the side of the groove-shaped opening 21b opposite to the elongated hole opening 21a. The other end of the mounting piece 213 is configured as a free end on the side of the elongated opening 21a in the grooved opening 21b. At an end on the free end side of the mounting piece 213, a convex portion 213a projecting upward is formed. The convex portion 213a protrudes above the substrate portion 211.

  When the operation dial portion 71 attached to the operation main body portion 72 is inserted into the elongated hole opening 21a, the flange portion 723 of the operation main body portion 72 presses the convex portion 213a, and the mounting piece 213 is elastically deformed. This allows the operation dial 71 to be introduced into the mounting position (see FIG. 6A). When the attachment piece 213 is elastically deformed, the operation dial portion 71 attached to the operation main body 72 is slid along the elongated hole opening 21a, and the attachment piece 213 elastically returns at the attachment position of the operation dial portion 71. As a result, the protrusion 213a returns to a position where the protrusion 213a protrudes above the substrate 211 (see FIG. 6B). Thus, the protrusion 213a of the attachment piece 213 restricts the movement of the flange portion 723 of the operation main body 72 toward the attachment piece 213. Therefore, the convex portion 213a of the mounting piece 213 restricts movement of the operation dial portion 71 in the removing direction.

  When the operation dial portion 71 is attached to the operation dial attachment portion 21 of the base plate 20, the operation dial portion 71 is arranged below the base plate 20. Therefore, the operation dial unit 71 is arranged at a position where it is difficult to visually recognize the operation dial unit from outside. The operation dial 71 disposed below the base plate 20 is operated by a user below the base plate 20.

Next, a procedure for attaching the operation dial unit 71 to the base plate 20 will be described.
First, in a state where the tank cover 50 is not attached to the base plate 20, as shown in FIG. 5, the operator places the operation dial 71 attached to the operation main body 72 below the base plate 20. From the side, in the portion where the upper side movement restricting portion 212a of the frame wall 212 is not formed, it is inserted into the elongated hole opening 21a.

  In this state, as shown in FIG. 6A, the flange portion 723 of the operation main body 72 presses the convex portion 213a of the mounting piece 213 on the open side of the frame wall 212. Thereby, the free end of the mounting piece 213 is pressed downward, and the mounting piece 213 is elastically deformed. Then, the flange portion 723 of the operation main body 72 abuts on the peripheral edge of the elongated hole opening 21 a in the substrate portion 211.

  Then, from this state, as shown in FIG. 6B, the operation main body 72 and the operation dial 71 are integrally slid to the side opposite to the open side of the frame wall 212. Accordingly, the flange portion 723 of the operation main body 72 moves to the gap 212b (see FIG. 5) below the upper side movement restricting portion 212a of the frame wall 212.

The upward movement of the flange portion 723 of the operation main body 72 is regulated by the upward movement regulating portion 212a of the frame wall 212. At the same time, the attachment piece 213 elastically returns, and the protrusion 213a of the attachment piece 213 restricts the movement of the flange portion 723 of the operation main body 72 in the removal direction.
In this manner, the operation dial 71 can be easily attached to the base plate 20 simply by inserting the operation dial 71 into the elongated hole opening 21a and sliding the operation dial 71, and the operation dial 71 It can be fixed to the operation dial mounting portion 21 of the base plate 20.

  Then, as shown in FIG. 2, the tank cover 50 is put on the washing water tank 30 so as to cover the washing water tank 30, and the lower end of the tank cover 50 is attached to the base plate 20. Then, the water discharge pipe fixing portion 43, the hand washing water discharge pipe 42, and the water discharge pipe clip 44 are attached. Further, the cleaning operation lever handle 81 is attached to the cleaning operation section 82.

  Conventionally, the operation dial portion 71 has been attached to the side surface of the tank cover 50. In detail, when attaching the operation dial portion 71 to the side surface of the tank cover 50, the operation of attaching the operation dial portion 71 to the side surface of the tank cover 50 is performed after covering the tank cover 50 on the washing water tank 30. . After the tank cover 50 is put on the washing water tank 30, the working space for attaching the operation dial portion 71 tends to be narrow.

However, according to the present invention, the operation dial portion 71 can be attached to the base plate 20 before the tank cover 50 is attached. Therefore, the operation dial unit 71 can be easily installed.
In particular, when the tank cover 50 is formed integrally with the hand washing bowl portion 41, the upper side of the tank cover 50 is closed. Therefore, the operation dial 71 can be attached to the base plate 20 before the tank cover 50 is attached.

Further, since the operation dial portion 71 is provided below the base plate 20, the operation dial portion 71 is arranged at a position that is difficult to be visually recognized from the outside. Therefore, the design is improved as compared with the case where the operation dial portion 71 is arranged on the side surface of the tank cover 50 as in the related art.
In the present embodiment, the installation position of the operation dial unit 71 is a position that is difficult to be visually recognized from the outside. Therefore, the user can be informed of the installation position of the operation dial portion 71 by writing it on a precautionary label and attaching it to the toilet bowl cleaning device 100 or by writing it in an instruction manual.

According to the toilet bowl cleaning device 100 of the present embodiment described above, the following effects are obtained.
The toilet cleaning device 100 includes a toilet body 11, a base plate 20 attached to the rear upper surface of the toilet body 11, a washing water tank 30 disposed on the base plate 20, a tank cover 50 covering the washing water tank 30, A water supply channel portion for supplying water, a water flow adjustment mechanism provided in the water supply channel portion, for adjusting a flow of water flowing through the water supply channel portion, and an operation dial portion 71 for operating the water flow adjustment mechanism, The base plate 20 is configured to have a portion where the washing water tank 30 is arranged (tank arrangement portion) and an operation dial attachment portion 21 to which the operation dial portion 71 is attached below the base plate 20.
Therefore, since the operation dial portion 71 is located below the base plate 20, the operation dial portion 71 is arranged at a position where it is difficult to visually recognize from outside. Thereby, designability can be improved.

  The base plate 20 has a partition part 22 that partitions the operation dial mounting part 21 and the tank arrangement part 23. Therefore, the operation dial mounting portion 21 is disposed in a partition 22 that is separated from a portion (tank placement portion) 23 of the base plate 20 where the washing water tank 30 is disposed. Thus, the operation dial mounting portion 21 is hardly affected by water from the washing water tank 30. Therefore, it is possible to suppress the operation dial portion 71 from getting wet with water.

The operation dial mounting portion 21 is a mounting piece 213 that allows the operation dial portion 71 to be introduced into the mounting position by being elastically deformed, and moves in the removing direction of the operation dial portion 71 by being elastically restored at the mounting position. Is provided.
Thus, the operation dial portion 71 can be easily attached to the operation dial attachment portion 21 without tools, and the operation dial portion 71 can be fixed at the attachment position.
Further, the operation dial portion 71 can be easily removed from the operation dial mounting portion 21 without using any tools.

The tank cover 50 is formed integrally with the hand-washing bowl portion 41 formed on the upper portion. The tank cover 50 is attached to the base plate 20 after the first step of attaching the operation dial section 71 to the base plate 20 and after the first step. Attaching a second step.
Thus, the operation dial portion 71 can be attached to the base plate 20 before the tank cover 50 is attached. Therefore, the operation dial unit 71 can be easily installed.
In particular, since the tank cover 50 is formed integrally with the hand-washing bowl portion 41, the upper side of the tank cover 50 is closed. Therefore, the operation dial 71 can be attached to the base plate 20 before the tank cover 50 is attached.

The second O-ring 741 is disposed between the main body tube 611 of the operation mechanism main body 610 and the flow rate adjusting cylinder 710 in a state of being disposed in the first inner peripheral water stopping groove 712. Thus, the second O-ring 741 stops water between the main body tube 611 of the operation mechanism main body 610 and the flow adjustment cylinder 710 below the flow adjustment cylinder 710.

  The second inner circumferential water stopping groove 713 is formed above the stop ring locking groove 714 in the flow rate adjusting cylinder 710. A third O-ring 742 is arranged in the second inner peripheral water stopping groove 713. The third O-ring 742 is arranged between the main body tube 611 of the operation mechanism main body 610 and the flow rate adjusting cylinder 710 in a state of being arranged in the second inner peripheral water stopping groove 713. As a result, the third O-ring 742 connects the main body tube 611 of the operation mechanism main body 610 and the flow adjustment cylinder 710 between the flow adjustment through hole 711 and the stop ring engaging groove 714 in the flow adjustment cylinder 710. Stop the water between them.

  As shown in FIGS. 15 and 16, the operation grip portion 720 is connected to the lower end of the flow rate adjusting cylinder 710 and extends downward from the flow rate adjusting cylinder 710. The operation grip portion 720 is formed in a substantially rectangular cylindrical shape, and penetrates vertically. The flow rate adjusting cylinder part 710 and the operation grip part 720 are formed linearly and continuously in the vertical direction, and their internal spaces communicate with each other in the vertical direction.

  The flange portion 730 is formed so as to protrude from the outer peripheral surface of the boundary between the flow rate adjusting cylinder portion 710 and the operation grip portion 720, and is formed in an annular plate shape that spreads in a substantially horizontal direction. The outer peripheral edge of the upper surface of the flange portion 730 is disposed at the peripheral edge of the through-opening 371 on the lower surface of the bottom plate portion 310 of the base plate 3 so as to face the lower annular protrusion 374 of the bottom plate portion 310. The flange portion 730 can be maintained in a horizontal state by being disposed so as to face the lower annular protrusion 374 of the bottom plate portion 310. Thereby, the inclination of the flange portion 730 is reduced, and the rattling of the operation dial portion 7 can be reduced.

  The stop ring 620 has a base 621 and a ring locking portion 622, as shown in FIG. The base 621 is a part that is gripped by hand. The ring locking portion 622 is formed in a substantially C shape. The closed end of the ring locking portion 622 is connected to the base 621. As shown in FIG. 15, the open end of the ring locking portion 622 is used to stop the operation dial portion 7 when the operation dial portion 7 is disposed inside the main body tube portion 611 of the operation mechanism main body portion 610. It is arranged in the groove 714. Thus, the stop ring 620 fixes the operation dial unit 7 to the operation mechanism main unit 610.

  The water flow suppressing unit 630 reduces the momentum of the makeup water discharged from the makeup water discharging unit 613a of the outlet pipe unit 613, and suppresses the force of the makeup water discharged from the makeup water discharging unit 613a. As shown in FIGS. 14 to 16, the water flow suppressing section 630 includes an opposing wall 631 and a roof wall 632.

  The facing wall portion 631 is formed so as to rise upward from the bottom plate portion 310 of the base plate 3, and is disposed to face the makeup water discharging portion 613 a of the outlet pipe portion 613. The opposing wall 631 receives the makeup water discharged from the makeup water discharge section 613a. The opposing wall portion 631 has one side connected to the upper peripheral wall 321 on the rear side of the base plate 3 and the other side extending toward the inside of the base plate 3. An arc-shaped projection 631a that protrudes in an arc shape is formed on the upper part of the opposing wall 631.

  The roof wall 632 is formed continuously with the outlet pipe 613 of the operation mechanism main body 610. The roof wall portion 632 extends in a substantially horizontal direction from the upper part of the water discharge port of the supply water discharge portion 613 a of the discharge pipe portion 613 toward the facing wall portion 631 so as to be away from the discharge pipe portion 613. The roof wall portion 632 has an arc-shaped portion 632a, and flat plate-shaped portions 632b, 632b.

The arc-shaped portion 632a is formed in an arc shape whose cross section in the front-rear direction protrudes upward, and linearly extends from the upper end portion of the supply water discharge portion 613a of the outlet pipe portion 613 toward the facing wall portion 631.
The plate-shaped portions 632b, 632b are formed substantially horizontally along both longitudinal edges of the arc-shaped portion 632a, and extend toward the opposing wall 631.

  The water flow suppressing section 630 configured as described above reduces the force of the makeup water discharged from the makeup water discharge section 613a of the outlet pipe section 613 by the opposing wall section 631, and moves upward by the roof wall section 632. Can be suppressed, and the momentum of the makeup water can be suppressed.

Next, a procedure for attaching the water flow adjusting mechanism 6 to the base plate 3 will be described.
First, as shown in FIG. 8, in a state where the upper cover 8a is not attached to the base plate 3, the operator can start the operation mechanism main body 610 of the water flow adjusting mechanism 6 from above the base plate 3 as shown in FIG. Is inserted into the cylindrical rib wall 372 of the water flow adjusting mechanism mounting portion 370 of the base plate 3 so that the lower end of the rectangular cylindrical portion 611b contacts the upper end of the cylindrical rib wall 372 of the water flow adjusting mechanism mounting portion 370. .

Next, the operation dial 7 is inserted into the operation mechanism main body 610 from below the base plate 3.
Subsequently, the stop ring 620 is inserted into the stop ring engaging groove 714 of the flow rate adjusting cylinder 710, and the operation dial 7 is fixed to the operation mechanism main body 610 by the stop ring 620.
Then, the distal end of the first branch channel 512a is attached to the introduction pipe 612 of the operation mechanism main body 610.
Thereby, the water flow adjusting mechanism 6 can be attached to the base plate 3.

  By arranging the stop ring 620 above the base plate 3, the water flow adjusting mechanism 6 can be assembled to the base plate 3 from above the base plate 3. Therefore, the assembling property when assembling the water flow adjusting mechanism 6 to the base plate 3 is good.

  Thereafter, as shown in FIG. 7, the upper cover 8 a is put on the washing water tank 4 so as to cover the washing water tank 4, and the upper cover 8 a is attached to the base plate 3.

In this state, as shown in FIG. 8, the operation dial 7 of the water flow adjusting mechanism 6 projects downward from below the base plate 3 at the rear of the base plate 3. Since the operation dial 7 is disposed below the base plate 3, a worker at the time of construction can operate the operation dial 7 below the base plate 3. Further, even after the installation, the operator can operate the operation dial section 7 without removing the upper cover 8a.
Therefore, even if the upper cover 8a is not removed from the toilet flushing device 100A, the operation dial unit 7 can be operated to adjust the amount of replenishing water supplied to the toilet main body 2a.

  In addition, since the operation dial part 7 adjusts the flow rate of the replenishing water supplied to the toilet body 2a, it is sufficient that an operator such as a contractor of the toilet cleaning apparatus 100A can operate the operation dial part. For example, when installing the toilet flushing device 100A or after installing the toilet flushing device 100A, the operator operates the operation dial unit 7 to adjust the flow rate of makeup water to be replenished to the toilet body 2a. Adjustment of the flow rate of make-up water by the operation dial unit 7 is not usually performed frequently, and is often used with the adjustment setting after being adjusted once. However, depending on the situation of the piping at the site where the toilet flushing device 100A is installed, when the toilet flushing device 100A is installed or after the toilet flushing device 100A is installed, the flow rate of the makeup water by the operation dial section 7 is determined. Adjustments may be required.

  Further, since the operation dial portion 7 is provided below the base plate 3, the operation dial portion 7 is arranged at a position where it is difficult to visually recognize the operation dial portion from the outside. Therefore, the design is improved compared to the case where the operation dial portion is arranged on the side surface of the upper cover 8a.

  In a state where the operation dial portion 7 is attached to the water flow adjusting mechanism attachment portion 370 of the base plate 3, the make-up water spouting portion 613 a is located on the upper side of the operation mechanism main body portion 610 separated upward from the bottom plate portion 310 of the base plate 3. At the position, the makeup water is discharged in a direction along the bottom plate portion 310. Since the makeup water spouting section 613a is arranged at a position above the operation mechanism main body 610, the operation dial section 7 arranged in the internal space of the operation mechanism main body 610 can be arranged at an upper position. Thereby, the amount of protrusion of the operation dial portion 7 below the base plate 3 can be reduced. Therefore, the operation dial portion 7 can be compactly arranged without protruding too much below the base plate 3. Therefore, the operation dial unit 7 can be arranged at a position where it is hardly noticeable, and erroneous operation of the operation dial unit 7 can be prevented.

  In the toilet flushing device 100A configured as described above, the water flow adjusting mechanism 6 adjusts the flow rate of the makeup water by changing the direction of the flow rate adjusting through hole 711 by rotating the operation dial section 7. be able to. Specifically, for example, the operator changes the opening area of the flow rate adjustment through-hole 711 by rotating the operation dial unit 7 in accordance with the situation of the piping at the site where the toilet flushing device 100A is installed. In addition, the flow rate of the replenishing water supplied to the toilet body 2a can be adjusted.

  When the toilet body 2a is washed, the makeup water whose flow rate is adjusted by the operation dial section 7 is discharged by the makeup water discharge section 613a of the water flow adjusting mechanism 6, and is once supplied to the base plate 3. The makeup water once supplied to the base plate 3 as makeup water flows through the first outlet inclined surface 311 and is discharged to the toilet main body 2a through the first outlet opening 361. Thereby, the makeup water whose flow rate has been adjusted by the water flow adjustment mechanism 6 is supplied to the toilet body 2a.

Here, in the toilet flushing device 100 </ b> A of the present embodiment, the water flow adjusting mechanism 6 is attached to the base plate 3. The operation dial 7 is attached to the base plate 3. For this reason, the operation dial unit 7 operates in the operation of the water flow adjustment mechanism 6 more than the case where the water flow adjustment mechanism 6 and the operation dial unit 7 are connected via a long connection cable such as a wire. Can be ensured widely, and the flow rate of the makeup water can be adjusted with high accuracy.
In particular, in the present embodiment, the water flow adjustment mechanism 6 is attached to the base plate 3 in a state where the operation dial section 7 is directly connected to the water flow adjustment mechanism 6. Since the operation dial unit 7 is directly connected to the water flow adjustment mechanism 6, the operation dial unit 7 can ensure a wider adjustment range of the flow rate of the makeup water in the operation of the water flow adjustment mechanism 6, It is possible to more accurately adjust the flow rate of the makeup water.

  Further, the makeup water discharge section 613 a discharges makeup water in a direction along the base plate 3. A water flow suppression unit 630 that suppresses the momentum of makeup water discharged from the makeup water discharge unit 613a is provided. The water flow suppressing unit 630 includes an opposing wall 631 and a roof wall 632. Therefore, the force of the makeup water discharged from the makeup water discharge section 613a can be reduced by the water flow suppression section 630 to reduce the strength of the makeup water discharged from the makeup water discharge section 613a.

  On the lower surface of the base plate 3, a first annular rib 381 formed so as to surround the first lead-out opening 361, and a second annular rib 382 formed so as to surround the first annular rib 381 are formed. ing. Therefore, on the lower surface of the base plate 3, the periphery of the first outlet opening 361 is surrounded by the double ribs, so that makeup water discharged from the toilet main body 2 a from the first outlet opening 361 may scatter around. Reduced.

  The first outlet opening 361 is arranged at a position overlapping at least a part 351 and 352 of the outlet pipe insertion opening 350 when the toilet body 2a is viewed in the front-rear direction. Therefore, the first lead-out opening 361 is disposed at a position avoiding the two branch hoses 412 and 412 of the distributor 410. Accordingly, since the makeup water discharged from the first outlet 361 is prevented from hitting the distributor 410, the makeup water is prevented from hitting the distributor 410 and scattering around.
