Instead of the switch 4, a water contact type or non-contact type sensor may be used.

FIG. 2 shows an example of the water supply / drainage device of the present invention in which the water storage tank 1 is connected to the drainage tank of an existing flush toilet, 5 is a drainage tank in an existing flush toilet, and 51 is a drainage lever thereof. Reference numeral 52 is a pipe for hand-washing, 6 is an existing mechanical valve installed in the drainage tank 5, 61 is its float, 7 is an existing water pipe, and 71 is a water quantity adjusting valve including closing. In the water storage tank 1, the tip of a pipe 32 is connected to the drainage tank 5, and here, the switch 31 of the electric drainage pump 3 is attached to the drainage tank 5 in association with the mechanical valve 6. As a result, the switch 31 is turned on and off in synchronization with the movement of the float 61 of the mechanical valve 6, and the drainage tank 5 has a predetermined amount, for example, one use. It is assumed that water is contained.

When the drain lever 51 is operated in this state to discharge the water in the drain tank 5 into the toilet, the float 61 of the mechanical valve 6 descends, and the switch 31 is turned on in synchronization with the movement of the float 61. Then, the electric drainage pump 3 is activated, and water is supplied from the water storage tank 1 to the drainage tank 5, and at the same time, tap water from the water pipe 7 is supplied to the drainage tank 5 as usual and is used for hand washing. Water for hand washing is discharged from the pipe 52. In this way, as the water is supplied from the water pipe 7 and the water storage tank 1 and the float 61 rises to reach a predetermined height as the water accumulates in the drainage tank 5, the mechanical valve 6 is closed and the switch 31 is closed. The electric drain pump 3 is turned off and the water supply from the water storage tank 1 to the drain tank 5 is stopped. Therefore, since the water supply to the drainage tank 5 in this mode is performed by the tap water and the water from the water storage tank 1, the usage amount of the tap water can be reduced.

Next, in FIG. 3, the water storage tank 1 is installed above the drainage tank 5 of the flush toilet, the water storage tank 1 and the drainage tank 5 are connected by a pipe 33, and water in the water storage tank 1 is connected. It is designed to be naturally dropped to the drainage tank 5, and the water pipe 7 is directly connected to the water storage tank 1 so that water can be supplied into the water storage tank 1 and a mechanical valve having a float 81 in the water storage tank 1. 8 are deployed. Here, the water pipe 7 was directly connected to the water storage tank 1, and the float 81 of the mechanical valve 8 was installed at the position of the amount of water for one wash, as an example. The reason is as follows. That is, in the apparatus of FIG. 3, the water used for washing is to use the water stored in the water storage tank 1, but if the water supply source such as the bathtub a runs out, and When the water in the tank 1 is also used up, the purpose is to supply only a single amount of water from the water pipe 7 to the water storage tank 1. It should be noted that the setting position of the float 81 may be a usage amount of one or more times of washing with water, and may be lower than the position of the float 41.

Thus, in the state of the water supply / drainage device of FIG. 3, one-time water used in the drainage tank 5 is supplied from the water storage tank 1 to the drainage tank 5. That is, when the drain lever 51 is operated in this state to discharge the water in the drain tank 5 into the flush toilet, the float 61 of the mechanical valve 6 descends, and this descends the mechanical valve 6 to open the water tank 1. The water flows into the drainage tank 5 in the form of a natural fall only for one washing. In this way, when the water in the water storage tank 1 in which water has accumulated up to the position of the float 41 is reduced by one wash, the float 41 of the mechanical valve 4 descends, and this descending activates the water supply pump 2 to supply the water supply sources a to d. When water is sent from the water tank 1 into the water storage tank 1 and the float 41 reaches a predetermined floating position, the water supply pump 2 is stopped. On the other hand, when the water level in the water storage tank 1 reaches the position of the float 81, that is, about one flush, when the water in this tank 1 flows into the drainage tank 5 for one flush, the mechanical valve 8 The float 81 descends to open the valve 8 and introduce tap water into the water storage tank 1. When installing the water storage tank 1 in the form shown in FIGS. 2 and 3, if the water storage tank 1 is integrally formed with the drainage tank 5 from the beginning, piping and columns for installing the tank 1 It eliminates the need for a stand or a stair.

As described above, the water storage tank 1 of the present invention sucks up unnecessary water in the bathtub a, the washing machine b, the rainwater tank c, and the septic tank d to store it, and supplies it to the drain tank of the flush toilet as necessary. Since the water can be supplied, tap water used for flush toilets can be saved.

Therefore, in the conventional flush toilet, tap water is usually used for flushing, but by connecting the water storage tank 1 to the drain tank 5 of the flush toilet, flushing can be performed without using tap water. On the other hand, the water pipe 7 connected to the drainage tank 5 can be connected to the water storage tank 1 to be shared with the electric water supply pump 2, or the conventional drainage tank connected to the water pipe can be used as the drainage tank 5. By using the water storage tank 1 together with the water storage tank 1, even if the water in the bath tank a or the like is insufficient, the water cannot be washed out.
