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) that adjusts the flow of water that flows through the water supply flow path portion (not shown) of the cleaning water supplied from the water supply portion 60 (see FIG. 2). .
The water flow adjusting mechanism (not shown) is provided in a water supply channel (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 portion 71 as an operation portion, an operation main body portion 72, and an operation cable 73 as a connection cable.

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

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

  The operation main body 72 is formed in a cylindrical shape, and includes a proximal end side cylindrical portion 721, a terminal end side cylindrical portion 722, and a flange portion 723. The base end side cylinder part 721 and the terminal end side cylinder part 722 are formed continuously in a straight line, and communicate with each other.

As shown in FIG. 4, the base end side cylindrical portion 721 has a base end side opening 721 a at the end on the base end side.
The operation cable 73 is inserted through the proximal end 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 terminal end side cylinder portion 722 has a terminal end side opening 722 a at the end portion on the terminal end side.
An operation dial portion 71 is disposed on the terminal end side cylinder portion 722. The operation dial portion 71 is rotatably attached to the end side opening 722a.

  The flange portion 723 is formed to extend along the circumferential direction on the circumferential surface of the approximate center of the operation main body portion 72 in the vertical direction (the boundary between the base end side cylindrical portion 721 and the terminal end 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 portion 71 is attached to the operation dial attachment portion 21 of the base plate 20 via the operation main body portion 72 so as to be positioned below the base plate 20.

  By rotating the operation dial 71 and operating it, 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 operate in the state which distribute | circulates a small amount of water via a flow valve, and the state which does not distribute | circulate water.

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

For example, the partition 22 is formed at a position that does not overlap with the cleaning water tank 30 arranged on the base plate 20 in a plan view (when viewed in the vertical direction). Therefore, the partition part 22 is formed at a position where water intrusion is suppressed even if water droplets adhering to the outer surface of the cleaning water tank 30 travel along the surface of the cleaning water tank 30 and fall on the base plate 20.
For example, the partition part 22 has the surrounding 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, the water stored on the bottom surface 20 a of the base plate 20 is prevented from entering the partition portion 22. The partition part 22 is not limited to enclosing the operation dial attachment part 21. For example, the partition portion 22 may be a wall portion that is disposed between the operation dial attachment portion 21 and the tank placement portion 23 and that does not surround the operation dial attachment portion 21.

As shown in FIGS. 3 to 5, an operation dial attachment portion 21 is disposed inside the peripheral wall portion 221 of the partition portion 22.
The operation dial attachment portion 21 includes a plate-like substrate portion 211, a substantially C-shaped frame wall 212, and attachment pieces 213.

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

The long hole opening 21a is a through hole extending in a predetermined direction, and is formed in a size that allows the operation dial portion 71 attached to the operation main body portion 72 to be inserted. The long hole opening 21a allows the operation dial part 71 to move in the length direction of the long hole opening 21a (the direction in which the long hole opening 21a extends) in a state where the operation dial part 71 attached to the operation main body 72 is inserted. Formed in size.
In addition, the long hole opening 21 a is formed in such a size that the flange portion 723 of the operation main body 72 cannot 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 main body portion 72 inserted into the long hole opening 21a It contacts the upper surface of the part 211.
A mounting piece 213, which will be described later, is disposed in the groove-shaped opening 21b.

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

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

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

  One end of the attachment piece 213 is fixed to the peripheral wall portion 221 of the partitioning portion 22 on the opposite side of the slot opening 21b from the long hole opening 21a. The other end of the attachment piece 213 is configured as a free end on the long hole opening 21a side in the groove-shaped opening 21b. A convex portion 213 a that protrudes upward is formed at the end of the attachment piece 213 on the free end side. The convex portion 213a projects upward from the substrate portion 211.

  The attachment piece 213 inserts the operation dial portion 71 attached to the operation main body portion 72 into the elongated hole opening 21a, whereby the flange portion 723 of the operation main body portion 72 presses the convex portion 213a and the attachment piece 213 is elastically deformed. This permits the introduction of the operation dial portion 71 to the mounting position (see FIG. 6A). The attachment piece 213 is elastically restored at the attachment position of the operation dial portion 71 by sliding the operation dial portion 71 attached to the operation main body 72 along the elongated hole opening 21a in a state where the attachment piece 213 is elastically deformed. Thus, the convex portion 213a returns to a position where it protrudes upward from the substrate portion 211 (see FIG. 6B). Thereby, the convex part 213a of the attachment piece 213 restricts the movement of the flange portion 723 in the operation main body 72 to the attachment piece 213 side. Therefore, the convex portion 213 a of the attachment piece 213 restricts movement of the operation dial portion 71 in the removal direction.

  In a state where 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 disposed below the base plate 20. For this reason, the operation dial portion 71 is disposed at a position that is difficult to visually recognize from the outside. The operation dial portion 71 disposed below the base plate 20 is operated by the user below the base plate 20.

Next, a procedure for attaching the operation dial 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 portion 71 attached to the operation main body portion 72 below and places the upper portion of the base plate 20 above. From the side, the frame wall 212 is inserted into the long hole opening 21a at a portion where the upper side movement restricting portion 212a is not formed.

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

  Then, from this state, as shown in FIG. 6B, the operation main body portion 72 and the operation dial portion 71 are integrally slid to the side opposite to the open side of the frame wall 212. As a result, 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 upper side movement restricting portion 212a of the frame wall 212 restricts the upward movement of the flange portion 723 of the operation main body portion 72. At the same time, the attachment piece 213 is elastically restored, and the flange portion 723 of the operation main body 72 is restricted from moving toward the removal direction by the convex portion 213a of the attachment piece 213.
Thus, the operation dial portion 71 can be easily attached to the base plate 20 by simply inserting the operation dial portion 71 into the long hole opening 21a and sliding the operation dial portion 71. It can be fixed to the operation dial mounting portion 21 of the base plate 20.

  Thereafter, as shown in FIG. 2, the tank cover 50 is placed on the washing water tank 30 so as to cover the washing water tank 30, and the lower end portion of the tank cover 50 is attached to the base plate 20. And the water discharge pipe fixing | fixed part 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 unit 82.

  Conventionally, the operation dial portion 71 is attached to the side surface of the tank cover 50. Specifically, when the operation dial portion 71 is attached 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 the tank cover 50 is put on the washing water tank 30. . After the tank cover 50 is put on the washing water tank 30, the work 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 part 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 effect of the present invention in which the operation dial portion 71 can be attached to the base plate 20 before attaching the tank cover 50 is great.

Further, since the operation dial portion 71 is provided on the lower side of the base plate 20, the operation dial portion 71 is disposed at a position that is difficult to visually recognize from the outside. Therefore, the design is improved as compared with the conventional case where the operation dial portion 71 is disposed on the side surface of the tank cover 50.
In the present embodiment, the installation position of the operation dial unit 71 is a position that is difficult to visually recognize from the outside. Therefore, the installation position of the operation dial unit 71 can be notified to the user by writing it on a note label and sticking it on the toilet bowl cleaning device 100 or writing it on the instruction manual.

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

  The base plate 20 has a partition portion 22 that partitions the operation dial attachment portion 21 and the tank placement portion 23. Therefore, the operation dial attachment portion 21 is disposed in a partition portion 22 that is partitioned from a portion (tank placement portion) 23 in the base plate 20 where the cleaning water tank 30 is disposed. Thereby, the operation dial mounting part 21 is not easily affected by water from the cleaning water tank 30. Therefore, it can suppress that the operation dial part 71 gets wet with water.

The operation dial attachment portion 21 is an attachment piece 213 that permits introduction of the operation dial portion 71 into the attachment position by elastic deformation, and moves in the removal direction of the operation dial portion 71 by elastically returning at the attachment position. It has the attachment piece 213 which regulates.
Thereby, the operation dial part 71 can be easily attached to the operation dial attachment part 21 without a tool, and the operation dial part 71 can be fixed at the attachment position.
Moreover, the operation dial part 71 can be easily removed from the operation dial attachment part 21 without a tool.

The tank cover 50 is integrally formed with the hand-washing bowl portion 41 formed on the upper portion. The first step of attaching the operation dial portion 71 to the base plate 20 and the tank cover 50 to the base plate 20 after the first step. A second step of attaching.
Accordingly, the operation dial portion 71 can be attached to the base plate 20 before the tank cover 50 is attached. Therefore, the operation dial part 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 effect of the present invention in which the operation dial portion 71 can be attached to the base plate 20 before attaching the tank cover 50 is great.
