Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows an outline of a toilet flushing water tank apparatus in the first and second embodiments. A reservoir 1 for storing flush water to be supplied to the flush toilet, and a flush water supplied to the reservoir 1 are fixed. It is composed of a ball tap 2 that automatically stops supply when water is stored up to the water level, drain valves 3 and 4 that open and close the cleaning supply path, and an operation lever 5 that opens and closes the drain valves 3 and 4 from the outside. Yes. The drain valves 3 and 4 are provided with a first drain valve 3 for small washing and a second drain valve 4 for large washing that are coaxially stacked one above the other, and each drain valve is constituted by a flapper valve. In addition, the height of the floats 32 and 42 attached in the middle of the ball chains 31 and 41 that are the connecting members of the drain valves 3 and 4 and the operation lever 5 changes the closing height of the drain valves 3 and 4, thereby cleaning the toilet bowl. The water volume is changed.

  2 to 4 are explanatory diagrams relating to the adjustment of the float height in the first embodiment. 2 is an explanatory view showing the structure of the drain valve in an exploded perspective view when FIG. 2 is fixed to the upper position of the float, FIG. 3 is fixed to the lower position of the float, and FIG. .

  First, the details of the height adjustment of the float 32 will be described for the first drain valve 3 for small washing. The first drain valve 3 has a ball chain 31 which is a connecting member connected to a flapper valve 35, a float 32 through which the ball chain 31 penetrates, retaining ring small portions 33a and 33b which serve as regulating members in the vertical position of the float 32, and the float. In the state where 32 is close to the upper retaining ring small 33a, it is inserted into the lower surface of the float 32 to prevent the float 32 from descending. In the state where the float 32 is adjacent to the lower retaining ring 33b, it is inserted into the upper surface of the float 32. The stopper ring 34 is a stopper member that prevents the rise.

  As shown in FIG. 2, the float 32 is composed of a disc portion 32a through which the ball chain 31 penetrates, and an annular portion 32b formed around the disc portion 32a and forming a cylindrical sealed space. When the small retaining ring 33a is inserted into the annular portion 32b and is substantially in contact with the circular plate portion 32a, the large retaining ring 34 is fitted into the ball chain 31 so as to substantially contact the lower surface of the annular portion 32b. The float 32 is held at the upper height position. As shown in FIG. 2, when the float 32 is held at the upper height position, when the flapper valve 35 is opened and the outflow of cleaning water is started and the water level in the water storage tank 1 is lowered, the float The time until 32 is exposed from the water surface and loses buoyancy is shortened. Therefore, the time during which the flapper valve 35 is opened is shortened, the amount of washing water is reduced, and water can be saved.

  On the other hand, there may be a case where it is desired to increase the amount of washing water and improve the drainage performance from the toilet. In that case, the retaining ring large 34 is pulled, and the retaining ring large 34 is extracted from the ball chain 31 through the notch 34c (see FIG. 4). Then, the float 32 is slid downward and the retaining ring large 34 is substantially in contact with the upper surface of the annular part 32b in a state where the disk part 32b substantially contacts the lower retaining ring small 33b as shown in FIG. The float 32 is held at the lower height position by being fitted into the ball chain 31 so as to come into contact. The retaining ring size is made of polypropylene resin, is easily elastically deformed, and is easily attached to and detached from the ball chain 31.

  As described with reference to FIGS. 2 and 3, the height adjustment range of the float 32 is restricted by the upper and lower retaining ring small portions 33a and 33b. For this reason, it is possible to prevent the float 32 from being installed at a high position where the amount of flushing water becomes too small to ensure the toilet flushing performance, and the toilet flushing failure can be prevented. Moreover, it can prevent that the float 32 is installed in an extremely low position, and can also prevent that a lot of washing water contrary to water saving is discharged | emitted. Further, the retaining ring large 34 that has to be attached to and detached from the ball chain 31 when adjusting the height of the float 32 has a larger diameter than the upper and lower retaining ring small 33a, b, so that the attachment / detachment operation is performed. On the other hand, the upper and lower retaining ring small portions 33a, b that do not require attachment / detachment operations are smaller in diameter than the retaining ring large portion 34, and are inserted inside the annular portion 32b of the float 32. The upper and lower retaining ring small portions 33a and 33b do not interfere with the ball chain 31, and a desired distance can always be maintained between the flapper valve 35 and the float 32.

  The second washing valve 4 for large washing is substantially the same in configuration as the first washing valve 3 for small washing described above, and a detailed description thereof is omitted. However, the ball chain 41 as a connecting member is a flapper. The float 42 is connected to the valve 45 and the ball chain 41 passes therethrough, the retaining ring small 43a, 43b serving as a regulating member in the vertical position of the float 42, and the float 42 in the state where the float 42 is close to the upper retaining ring small 43a. The float 42 is inserted into the lower surface to prevent the float 42 from descending. When the float 42 is close to the lower retaining ring 43b, the float 42 is inserted into the upper surface of the float 42 and serves as a stopper ring 44 that serves as a stopper member that prevents the float 42 from rising. As shown in FIGS. 2 and 3, the height of the float 42 can be adjusted within a range regulated by the upper and lower retaining ring small portions 43a and 43b.

  5 and 6 show a second embodiment. FIG. 5 shows a case where the float height is held on the upper side, and FIG. 6 shows a case where the float is held on the lower side. The second embodiment is different from the first embodiment described above in that the regulating member for regulating the position of the floats 32 and 42 to the lower side is the drain valve itself.

  Specifically, the first drain valve 3 for small cleaning will be described. As shown in FIG. 5, the upper retaining ring small portion 33a is inserted inside the annular portion 32b and is substantially in contact with the disc portion 32a. The float 32 is held at the upper height position by fitting the large retaining ring 34 into the ball chain 31 so as to substantially contact the lower surface of the annular portion 32b.
