In addition, the opening and closing valve 6a is installed so that the first float 6 is submerged in the water of the auxiliary tank 2 so as to open the water supply pipe 4 when a small amount of recycled water inside the auxiliary tank 2 remains.

At this time, the first float (6) is detachably installed from the on-off valve (6a) detachably, the hook to bind the first float (6) in the lowered state at the predetermined position on the bottom side of the auxiliary tank (2) 14 and the binding strap 14a are provided, and at the predetermined position of the discharge port 4b, a binding strap 14b is provided to bind the third float 8 in a floating state so that the wash water of the flush toilet is only tap water. In use, the shut-off valve 6a is opened and the recycle water supply pipe 3 is closed.

In addition, an overflow water drain pipe 11 for draining the recycle water inside the auxiliary tank 2 to the outside at a predetermined position on the upper side of the auxiliary tank 2 is provided, and the overflow water drain pipe 11 is an overflow water drain pipe ( 11) the distal end of the overflow tank 11 to the drain pipe 5 inside the main tank 1 so as to allow the overflow water to flow down into the valve body, or in another embodiment, the distal end of the overflow tank 11 It can be pulled out and flows down to a drain in the bathroom floor.

In addition, after embedding the lower portion of the main body 4a of the water supply and water supply pipe 4 to the position where the user of the floor of the toilet is to step, the user installs the pedal valve 9 at the position where the user will step, and the user flushes for toilet. When sitting on the toilet (toilet flush toilet and squat flush), the pedal valve 9 stepped on the user's foot is opened to allow the tap water to be supplied to the main tank (1) side. In another embodiment, the use of tap water is possible by the first and second floats 6 and 7 without the pedal valve 9, or even when the pedal valve 9 is present and the on / off valve 6a is absent. Can be used.

However, when the tap water is supplied to the main tank 1, both the first and second floats 6 and 7 must descend to open the discharge port 4b.

A branch pipe (13a) capable of supplying tap water to the bidet (13) is branched at a predetermined position below the main body (4a) of the water supply and demand pipe (4), and the branch pipe (13a) uses a bidet (13). If not, the closure is possible.

Figure 3 shows another embodiment of the present invention, in which the present invention by another embodiment is similar to the present invention in one embodiment, where the water supply pipe 4 is somewhat different from the auxiliary tank 2 in one embodiment. Although passed through, in another embodiment the water supply pipe 4 is installed between the main tank 1 and the outer side of the auxiliary tank (2).

As described above, as the water supply and water supply pipe 4 is installed between the outer side of the main tank 1 and the auxiliary tank 2, the opening / closing valve 6a in which the first float 6 is installed is predetermined above the main body 4a. The rod 6b of the 1st float 6 is bent downwardly so that it may be provided in the position and the 1st float 6 will be located in the water below the auxiliary tank 2.

Reference numeral 16 in the reference numerals denotes a valve for draining the recycled water when the inside of the auxiliary tank 2 is cleaned or when recycled water is used as the waste water.

Looking at the effects of the present invention configured as described above are as follows.

First, it will be described from the case where all the water is exhausted inside the main tank (1) and the auxiliary tank (2), in the flush toilet using the domestic wastewater of the present invention is installed to be submerged in the water of the inner bottom of the auxiliary tank (2) When water is consumed inside the auxiliary tank 2 by the first float 6, and a small amount of recycled water is left, tap water is supplied from that time, and thus all the recycled water inside the auxiliary tank 2 is exhausted. I will explain it.

As described above, a small amount of recycled water remaining inside the main tank 1 and remaining inside the auxiliary tank 2 flows into the main tank 1 through the recycle water supply pipe 3 to the main tank 1. The washing water is filled in the inner side of the stool to prepare.

When the washing water is filled inside the main tank (1) as described above, the auxiliary tank (2) becomes empty and accordingly the first float (6) is lowered to open the water supply pipe (4), but in this situation When the toilet is not used, the tap water supply pipe 4 is closed so that the pedal valve 9 is not stepped on by the user so that no tap water is supplied to the tap water supply pipe 4, and only the washing water is supplied to the main tank 1. It will be filled.

In this state, when the recycled water is drained from the wash basin 12 or the like during a predetermined time, the recycled water is introduced into the auxiliary tank 2 and the recycled water is filled inside the auxiliary tank 2.

As described above, when the user sits on the flush toilet in a state where the recycling water is filled in the auxiliary tank 2, the pedal valve 9 is stepped by the user to open the pedal valve 9, but the main tank 1 ) And the auxiliary tank 2 are filled with water, so that the first and second floats 6 and 7 both float, and the main body 4a and the shut-off valve 6a are both closed to prevent supply of tap water. do.

Under such a situation, when the user operates the drain lever 10 and the washing water is drained through the drain pipe 5, the second float 7 and the third float 8 descend, but at this time, the second float 7 Since the first float 6 floats even when descending, the water supply pipe 4 is blocked by the opening / closing valve 6a, so that tap water is not supplied to the main tank 1, and is opened by the third float 8 falling. Through the recycled water supply pipe (3), only the recycled water received in the auxiliary tank (2) is introduced into the main tank (1).

If the recycled water filled in the auxiliary tank 2 is consumed while using the flush toilet several times as described above, and a small amount of water is left, the first float 6 descends and the opening / closing valve 6a is opened. Let's go.

At this time, when the washing water inside the main tank (1) is drained and empty, a small amount of water remaining in the auxiliary tank (2) is introduced into the main tank (1), and thus the auxiliary tank (1) to the main tank (1) When the recycled water remaining in 2) flows in, the second float 7 installed on the upper inner side of the main tank 1 floats and blocks the discharge port 4b, so that clean tap water is supplied to the inner side of the main tank 1. It becomes impossible.

In this state, while the user sits on the flush toilet while watching the toilet to drain the washing water received in the main tank (1), both the washing water of the main tank (1) and the auxiliary tank (2), the first, second Both the floats 6, 7 and the third float 8 are lowered so that both the on-off valve 6a and the discharge port 4b provided in the main body 4a of the water supply and demand pipe 4 are opened.

In this way, both the on-off valve 6a and the discharge port 4b provided in the main body 4a of the water supply and drainage pipe 4 are supplied to the main tank 1 through the water supply and supply water supply pipe 4 through the open drawing. In the same manner as using a toilet, when the wash water inside the main tank 1 is drained, the tap water is supplied to the main tank 1 through the water supply pipe 4, and when the supplied tap water reaches a predetermined level, the second float 7 ) Rises to block the discharge port 4b of the water supply and water supply pipe 4 to stop the supply of tap water.

When the user uses the flush toilet and gets out of the toilet, the pedal valve 9 stepped on by the user's foot is blocked and no more tap water is supplied.

Then, when using the flush toilet as described above, when the recycled water flows into the auxiliary tank (2), the first float (6) floats while the on-off valve (6a) is installed at a predetermined position of the main body (4a) of the water supply water supply pipe (4) ) To stop the supply of tap water.

Recycling water continues to flow into the auxiliary tank 2 even when the on-off valve 6a is blocked as described above, and the recycled water flowing in more than the amount set in the auxiliary tank 2 overflows the drain water pipe 11. Through the drain tank 5 is installed in the outer side of the auxiliary tank (2) or the inner side of the main tank (1).

In addition, when using the flush toilet using the domestic wastewater of the present invention as the recycling water as described above, when the user wants to use only clean tap water without using recycled water, the first float 6 opens and closes the valve 6a. Or the first float 6 is tied together so that the opening / closing valve 6a is always open by using the ring 14 and the tie string 14a, and the third float 8 floats. When the recycling water supply pipe 3 is closed, the water supply water supply pipe 4 is always open, and the tap water supply pipe 4 is always open so that the tap water can be used as if using a general flush toilet. , Recycling water of the auxiliary tank (2) will not flow into the main tank (1).

In addition, a check valve 15 is installed at a predetermined position of the recycling water supply pipe 3 to prevent the washing water from the main tank 1 from flowing back to the auxiliary tank 2 so that the washing water is filled only in the main tank 1. And when there is no water in the auxiliary tank (2) it is possible to prevent the wash water inside the main tank (1) to flow back to the auxiliary tank (2).

On the other hand, the branch pipe (13a) is branched so that the tap water 13 can be supplied to the bidet 13 at a predetermined position below the water supply and drainage pipe (4), and the bidet can be used conveniently. 13a).

The flush toilet using the domestic waste water according to the present invention as described above, the pedal valve which is opened by stepping on the user's foot when sitting to use the flush toilet, the auxiliary tank is filled with recycled water and the main tank is not washed water The first flop for opening the water supply pipe only and the second float for blocking the supply of tap water by blocking the discharge port in accordance with the water level inside the main tank are installed in multiple stages, so that the tap water is only available when there is no recycle water inside the auxiliary tank. It is configured to be supplied is an advantage that can minimize the use of tap water.

In addition, it has the convenience of using recycled water or by selecting only clean tap water according to the user's convenience.
