The case where the drainage amount adjusting device according to the present embodiment configured as described above is installed in a flush valve type flush toilet tank provided with a valve guide ring will be described. First, a valve presser (1) in which a pair of sliding parts (5) and (5) are fitted to a guide rail (6) is prepared, and a guide rail fixed at a lower end of the guide rail (6) is fixed. Part (7) is fitted to the overflow pipe (10), and then the guide rail (6) is positioned with the valve pressing part (3) aligned with the valve guide ring (11). The latching part (8) provided at the upper end of the pipe is sandwiched and locked so as to be hooked on the upper end opening of the overflow pipe (10). In this case, since the locking portion (8) is formed in a clip shape and has a clamping function, the guide rail (6) can be easily positioned and mounted on the upper end of the overflow pipe (10). it can. When mounting the guide rail (6) to the overflow pipe (10), with the valve pressing part (3) aligned with the valve guide ring (11), use a fixing means such as a tightening screw to guide the guide rail (6). The fixing part (7) may be fastened and fixed to the overflow pipe (10). Finally, the lid member (4) is opened and water is injected to predetermined scales (L1, L2, L3), and the installation of the drainage amount adjusting device is completed. This state is shown in FIG.

Next, the operation of the drainage amount adjusting device according to the embodiment of the present invention will be described. (i) As shown in Fig. 2, in the initial state where the drainage amount adjustment device is installed in the tank (30), a predetermined amount of washing water is supplied into the tank (30), and a ball tap is made via the float (35). The faucet (33) is closed and maintained at a predetermined high water level (WL1). In this state, the valve presser (1) is located near the upper end of the guide rail (6) according to the level (L1, L2, L3) of the water injected into the valve presser (1). Further, the float valve (20) is seated on the valve seat (13) of the drain port (17), and the washing water in the tank (30) is not drained. (ii) Next, as shown in FIG. 3, when the operation lever (24) is turned and the float valve (20) is pulled through the chain (23), the float valve (20) is moved to the valve seat ( 13), the washing water in the tank (30) is discharged to the toilet bowl (not shown) through the drain port (17). Here, the float valve (20) pulled upward is held at the valve-opening position by the buoyancy of the washing water in a state of contact with the valve guide ring (11). (iii) Thereafter, as shown in Fig. 4, when the water level of the washing water decreases due to the drainage action, the valve pressing body (1) also descends along the guide rail (6), and the water level of the washing water decreases. When the predetermined water level (WL2) is reached, the valve pressing part (3) fits into the valve guide ring (11). At this time, since the upper surface of the float valve (20) is pushed in with the lower surface of the valve pressing part (3), the float valve (20) is forcibly seated on the valve seat (13), and the drain port (17) is closed. The drainage action ends. In the conventional drainage device (see FIG. 7), the valve is not closed until the water level of the washing water is further lowered, but in the case of the drainage amount adjusting device according to the present embodiment, the float is pressed by the valve pressing body (1). Since the valve (20) is forcibly depressed, the washing water is not discharged excessively. (iv) When the drain port (17) is closed by the float valve (20), the washing water is no longer drained from the drain port (17), so the ball tap water tap (33) is opened via the float (35). Then, new washing water is supplied from the water supply pipe (32) into the tank (30), and returns to the initial state as shown in FIG. (v) To change the amount of drainage, it is only necessary to open the lid member (4) and inject and drain the amount of water in the valve presser (1) to a predetermined level (any of L1, L2, and L3). Also, changing the level of water in the valve presser (1) only changes the position of the floating valve presser (1) with respect to the water surface, and the water supplied through the float (35) is washed. Since the amount of water, that is, the level of the washing water stored in the tank (30) does not change, the water pressure acting during drainage does not change.

A modification of the embodiment of the present invention will be described with reference to FIG. In the valve pressing body (1A) according to this modification, the valve pressing portion (3A) that comes into contact with the float valve and presses down in the valve closing direction is formed to have a smaller diameter than the valve pressing body (2A) and has a valve guide ring. It is designed to be inserted inside. When attaching the guide rail (6A) to the overflow pipe (10), the guide rail fixing part (7A) to be inserted into the overflow pipe (10) is installed at two places in the vertical direction, and the overflow pipe (10) is The guide rail (6A) can be mounted at any height. In addition, the sliding part (5A), which connects the valve presser (1A) to the guide rail (7A) so that it can move up and down, is expanded and contracted in the horizontal direction via a turnbuckle mechanism (5B) with reverse threads on both sides. It is freely configured. With this configuration, even if the gap between the overflow pipe (10) disposed in the ready-made flush toilet tank and the float valve or the flapper valve varies, the valve pressing part of the valve pressing body (1A) can be used. By adjusting (3A) so as to be arranged at a position where it can reliably contact the float valve or the flapper valve, the valve presser (1A) can be operated properly. In FIG. 5, a lid member (4A) for pouring and draining is formed in the valve pressing body (2A), and a scale (L1, L2, L3) for visually checking the amount of water to be injected into the inside. ) Is displayed.

Next, another embodiment of the present invention will be described with reference to FIG. In this embodiment, a case will be described in which a valve presser is installed in a flapper valve type drainage device, but the same components are denoted by the same reference numerals. The valve pressing body (1) for adjusting the drainage amount is the same as the embodiment shown in FIGS. 1 to 4, and the guide rail fixing part (7) is attached to the existing overflow pipe (10) arranged in the tank. Attach the guide rail (6) to the upper end of the overflow pipe (10) by holding the clip-shaped engaging part (8) fixed to the upper end of the guide rail (6) so that the guide rail (6) is hooked. Attach to the overflow pipe (10). In this case, the range of movement of the valve pressing body (1) is defined by the height of the overflow pipe (10), so if the distance between the valve pressing part (3) and the flapper valve (20A) is too large, Alternatively, a guide rail (6A) as shown in FIG. 5 may be used.

When the flush toilet is washed, the operation lever (not shown) is rotated to open the flapper valve (20A) via the chain (23), whereby the washing stored in the tank is washed. Water is drained into the toilet bowl. In this case, the vertical position of the valve pressing body (1) is determined according to the amount of water injected into the valve pressing body (1), so that the amount of water injected into the valve pressing body (1) is appropriately adjusted. By controlling the valve closing time of the flapper valve (20A), it is possible to adjust to a desired amount of drainage. Further, in the embodiment shown in FIG. 6, a float (34) attached to a connecting rod (34) connected to a ball tap water faucet (33) (see FIG. 2) provided in an existing tank. 35) Remove (see Fig. 2) and install the valve presser (1) in the overflow pipe (10) so that the tip of the connecting rod (34) is located in the movement path of the valve presser (1). You. With this configuration, the washing water in the tank is drained every time the flush toilet is washed, but after the flapper valve (20A) is closed, the predetermined washing water is stored in the tank. As the upper surface of the valve pusher (1) comes in contact with the lower end of the connecting rod (34), the connecting rod (34) is pushed upward, and a predetermined amount of washing water is stored in the tank. The ball tap faucet (33) can be closed. Although the other embodiment according to FIG. 6 has been described in the case where the valve pressing body is installed in the flapper valve type drainage device, the case where it is installed in the float valve type flush toilet tank where the valve guide ring is installed is described.
