There is a problem that the sound of landing when falling is increased.
Accordingly, it is desirable that the water outlet 316 in the tank be inclined obliquely downward toward the tank wall located in the front-rear direction (perpendicular to the paper surface) in FIG. 7. Use the same ball tap with the left water supply that supplies water to the ball tap device from the left side and the right water supply that supplies water from the right side to the ball tap device with the external pipe on the right side. The problem of being unable to do so arises.

  If the same ball tap device is used in both the case of left water supply and the case of right water supply by reversing the left and right directions in FIG. 7, the direction of the water outlet in the tank is the same as that in FIG. This is because the directions are different in the perpendicular direction.

As a prior art to the present invention, the following Patent Document 1 discloses an invention relating to a low tank structure, in which a ball tap device intended to cope with the presence or absence of a hand-washing water discharge pipe is disclosed.
However, the one disclosed in Patent Document 1 uses a water conduit formed of a bellows tube in both cases with and without a hand-washing water discharge tube, which is different from the present invention. is there.

Here, the water guide pipe 54 is formed of a bellows pipe, and the tip side thereof is connected to the hand-washing water discharge pipe 18.

As shown in FIG. 2, the main body pipe 44 is provided with a water supply valve 58 that communicates and blocks the water channel 56. The water supply valve 58 is opened and closed as the connecting arm 30 rotates around the shaft 60 as the float 28 moves up and down.
Specifically, the linkage arm 30 is rotated counterclockwise around the shaft 60 by the rise of the float 28, whereby the water supply valve 58 is closed, and the linkage arm 30 is pivoted as the float 28 is lowered. The water supply valve 58 is opened by rotating around 60 in the clockwise direction in the figure.

Thus, when the water supply valve 58 is opened, the water channel 56 is in a communication state, that is, an open state, so that water from the external water supply pipe 26 flows from the main body pipe 44 to the connection pipe 46 and is discharged into the tank of the connection pipe 46. Water is discharged from the water port 50 into the cleaning tank 10, and is discharged to the hand-washing water discharge pipe 18 (when the hand-washing water discharge pipe 18 is present) through the hand-washing water supply port 52 or water is discharged into the washing tank 10 through the hand-washing water supply port 52. (When the hand washing water discharge pipe 18 is not provided).
Further, the water that has flowed into the connecting pipe 46 further flows from the overflow pipe 42 to the toilet through the make-up water pipe 48, and the make-up water is supplied to the toilet.

In this embodiment, the water supply valve 58 is a diaphragm type and pilot type valve.
FIG. 3 specifically shows the configuration.
In FIG. 3, reference numeral 62 denotes a main valve in the water supply valve 58, which is a diaphragm valve.
The main valve 62 includes a diaphragm film 66 made of an elastic material such as rubber, and a diaphragm holder 68 that is harder (here, made of resin).

The outer peripheral portion 70 of the diaphragm film 66 is thick, and the outer peripheral portion 70 is vertically sandwiched between the main body tube 44 and a cup-shaped diaphragm presser 72. The outer peripheral portion 70 of the diaphragm film 66 is fixed to the main body tube 44 by sandwiching them.
Here, the outer peripheral portion 70 of the diaphragm film 66 simultaneously functions as a seal portion, that is, functions to seal and seal the water channel 56 and the outside in a watertight manner.

  The cup-shaped diaphragm retainer 72 is fitted into a cylindrical portion 74 integrally formed with the main body tube 44 so as to be fitted in an upward direction from the lower side in the figure, and is externally threaded on the outer peripheral surface of the cylindrical portion 74. The diaphragm retainer 72 is fixed to the cylindrical portion 74, that is, the main body tube 44 by screwing the female thread portion 78 on the inner peripheral surface of the cap nut 80 to the portion 76.

  That is, in this embodiment, when the cap nut 80 is screwed upward in the drawing, the diaphragm retainer 72 fitted in the cylindrical portion 74 is pushed upward, and the diaphragm retainer 72 cooperates with the main body tube 44. Thus, the outer peripheral portion 70 of the diaphragm film 66 is structured to be elastically compressed with a predetermined tightening allowance.

The cup-shaped diaphragm retainer 72 also has a function as a back pressure chamber forming member, and forms a back pressure chamber 82 behind the lower side of the main valve 62 made of a diaphragm valve in the figure.
The back pressure chamber 82 causes the internal pressure to act on the main valve 62 as a pressing force in the upward valve closing direction in the figure.

On the other hand, the main valve 62 is provided with a through-introducing small hole 84 that allows the primary side of the water channel 56 to communicate with the back pressure chamber 82 at a position eccentric from the center.
The introduction small hole 84 functions to increase the pressure of the back pressure chamber 82 by causing the primary water in the water channel 56 to flow into the back pressure chamber 82.

On the other hand, the diaphragm presser 72 is provided with a pilot water channel 86 as a drainage water channel penetrating through the center thereof.
The pilot water channel 86 serves to drain the water in the back pressure chamber 82 and reduce the pressure in the back pressure chamber 82.

  A pilot valve 88 is provided at the base end portion of the arm portion 32 of the linkage arm 30, and the pilot water passage 86 is closed when the seal portion 90 of the pilot valve 88 is seated upward on the pilot valve seat 92.

That is, as shown in FIG. 4A, when the water supply valve 58 is closed, the connecting arm 30 is rotated around the shaft 60 by the lowering of the float 28 shown in FIG. When the valve is opened downward and opened in the figure, the water in the back pressure chamber 82 in FIG. 3 flows out through the pilot water channel 86 and the pressure in the back pressure chamber 82 decreases.
Then, the primary side pressure in the water channel 56 overcomes the pressure in the back pressure chamber 82, and the main valve 62 is opened downwardly from the state shown in FIGS. 3 (A) and 4 (A).

When the main valve 62 is opened, the water channel 56 is in communication, and water flows from the main body pipe 44 toward the connection pipe 46 and the replenishment water pipe 48 in FIG.
Here, water is discharged from the tank water outlet 50 and the hand-washing water supply port 52, and makeup water is further supplied from the overflow pipe 42 into the toilet through the makeup water pipe 48.

  On the other hand, when the linkage arm 30 pivots counterclockwise around the axis 60 in FIG. 2 in conjunction with the rise of the float 28, the water in the washing tank is set when the float 28 reaches the rise end. When the water is full, the seal portion 90 of the pilot valve 88 is seated upward on the pilot valve seat 92 and closes, where water outflow from the back pressure chamber 82 stops.

Then, the pressure of the back pressure chamber 82 rises due to the inflow of water into the back pressure chamber 82 through the introduction small hole 84, and the main valve 62 composed of a diaphragm valve is seated upward on the main valve seat 64 by the pressure rise, Close the valve.
Here, the flow of water in the water channel 56 is stopped, and water supply to the washing tank 10 and the hand washing water discharge pipe 18 is stopped.

As shown in FIGS. 3A and 4, a metal coil spring 95 is provided inside the back pressure chamber 82.
The upper end of the coil spring 95 is brought into contact with the main valve 62 and the lower end thereof is brought into contact with the bottom of the diaphragm retainer 72.

A cleaning pin 97 extends upward from the lower end of the coil spring 95 in the figure, and this cleaning pin 97 is inserted through the introduction small hole 84 in the main valve 62 and protrudes upward.
When the main valve 62 moves up and down in FIGS. 3 and 4, the cleaning pin 97 moves relative to the inside of the introduction small hole 84 to prevent clogging of fine dust and foreign matters in the introduction small hole 84. It has a function to prevent.
In this embodiment, the cleaning pin 97 extends from the lower end of the coil spring 95 in a straight shape upward in the drawing, and is then bent slightly above the main valve 62. In the figure, 98 represents the bent portion.

  By the way, there are two types of washing tanks, such as the washing tank 10 of FIG. 1, provided with the hand washing water discharge pipe 18 and those not provided with the hand washing water discharge pipe 18. If not provided, the hand-washing water supply port 52 is opened as it is without connecting the water conduit 54 to the hand-washing water supply port 52.

  That is, in this embodiment, when the hand wash water discharge pipe 18 is provided, the water guide pipe 54 is connected to the hand wash water supply port 52, and when the hand wash water discharge pipe 18 is not provided, the water guide pipe is connected to the hand wash water supply port 52. By connecting the water supply port 52 for hand-washing as it is without connecting 54, it respond | corresponds with the thing with and without a hand-washing water discharge pipe.

Thus, when the washing tank 10 does not include the hand-washing water discharge pipe 18 and the water guide pipe is not connected to the hand-washing water supply opening 52 but is left open as it is, the water in the water flow pipe 100 is discharged from the water discharge outlet 50 in the tank. Water is discharged from both the water supply port 52 and the hand-washing water supply port 52.
At this time, if the hand-washing water supply port 52 faces upward in the horizontal direction, the water in the water conduit 100 is discharged upward from the hand-washing water supply port 52.
Therefore, here, in addition to the tank water outlet 50 being provided downward, the hand-washing water supply port 52 is also provided downward.
In this case, the water in the water conduit 100 is discharged downward from the hand-washing water supply port 52 into the washing tank.
At this time, the hand-washing water supply port 52 functions as a second tank water discharge port.

However, if both the tank water outlet 50 and the hand wash water supply port 52 are directed downward, that is, vertically downward, water discharged from the tank water discharge port 50, water discharged from the hand wash water supply port 52 (the water conduit 54 is connected). However, when it is not connected, the sound of landing on the surface of the cleaning water stored in the cleaning tank 10 increases.
Therefore, in this case, both the tank water outlet 50 and the hand-washing water supply port 52 are inclined downward, specifically, toward the front tank wall W in the direction perpendicular to the paper surface in FIG. It is provided in an angled direction.

In this embodiment, the fitting recess 110A having a small shape also serves as a locking portion that locks the claw 104A or 104D.

  In this embodiment, the connection tube 46 is inserted into the main body tube 44 only when the connection tube 46 is inserted into the main body tube 44 so as to fit the fitting recess 110A with the claws 104A or 104D. It can be connected to.

  Specifically, for example, as shown in FIGS. 6A and 6C, when the connecting tube 46 is inserted into the main body tube 44 so that the fitting concave portion 110A is engaged with the claw 104A, the main body tube 44 side is inserted. The claw 104B enters the notch 108B of the connecting pipe 46, the claw 104C fits into the engaging portion 110C made of a large through hole, and the small claw 104D enters the notch 108D. .

At this time, the connection pipe 46 is prevented from being pulled out from the main body pipe 44 based on the engagement between the claw 104A and the fitting recess 110A that also serves as the engagement portion, and the elastic engagement between the claw 104C and the engagement portion 110C.
Further, in this connected state, the tank water outlet 50 and the hand-washing water supply port 52 of the connection pipe 46 are vertical surfaces in a front view with respect to the pipe end on the downstream side of the main body pipe 44 as shown in FIG. It will be in a state facing the left side. Specifically, it is in a state where it is oriented in a direction inclined by an angle θ with respect to the vertical plane.

On the other hand, as shown in FIGS. 6B and 6D, when the connecting pipe 46 is inserted into the main body pipe 44 so that the fitting recess 110A is engaged with the claw 104D, the claw 104A is notched. 108B, the claw 104B fits into the engaging portion 110C made of a large through hole, and the claw 104C enters the notch 108D.
At this time, as shown in FIG. 6D, the tank water outlet 50 and the hand-washing water inlet 52 face the right side with respect to the vertical plane, specifically, the right angle by the angle θ with respect to the vertical plane. It is in a state of facing diagonally downward.
