The present invention is a device for utilizing the relatively clean sewage generated in the building toilet as the washing water of the flushing toilet to transfer the clean sewage stored in the clean sewage reservoir to the water tank of the flush toilet without the additional power using the water pressure of the water source. It is a device for.

Currently, Korea is classified as a water shortage country, and building technology that can recycle water in the future when water resources are depleted is a necessary invention.

In particular, in the sewage drained from a building toilet washbasin or bathtub, even though it is clean enough to be used as washing water of a flush toilet without a separate water purification process, it was discharged as sewage, which was a big waste of water resources.

Inadvertently discarded water, such as when you wash your hands without soap, for example, when you take a warm shower in winter or draw hot water that has already been cooled down for washing your face, is released as sewage.

If it is clean sewage that does not require water purification, it can be used as washing water in a flush toilet.

However, in order to transfer clean sewage to the water tank of the flush toilet, a separate power source such as a manpower or a pump is needed, and it is not annoying for the human being or the device is complicated, and the sewage was not recycled.

The technical problem of the present invention is to push the clean sewage contained in the clean sewage reservoir 201 by the water pressure of the water supply source 101 without a separate power in the building toilets to the tap water 105 of the flush toilet to clean clean sewage Nozzle 204 inside the joint pipe 203 connecting the clean water supply pipe 205, the clean water supply pipe 103, and the water supply pipe 102 to the clean water supply pipe supplied from the water supply source 101 to be supplied. The technical problem that the clean sewage is supplied to the water storage tank 105 of the flush toilet by pushing the clean water into the joint pipe 203 from the clean sewage water tank 201 with the tap water converted into a stream of strong pressure through Shall be.

The configuration of the present invention is a clean sewage reservoir 201 for storing clean sewage;

A clean sewage discharge pipe 205 formed under the clean sewage reservoir 201 to discharge clean sewage to the outside;

A check valve 202 for controlling the flow of fluid so that clean sewage flows only toward the joint pipe 203 without flowing back of the clean sewage in the middle of the clean sewage discharge pipe 205;

And it is composed of a joint pipe 203 formed with a nozzle 204 inside the joint pipe 203 connecting the clean sewage discharge pipe 205, the water supply pipe 102, and the washing water supply pipe 103, respectively with the drawing. The detailed description is as follows.

In FIG. 1, when the flush toilet 104 is cleaned, the water level of the water tank 105 of the flush toilet is lowered to open the float valve 106, and the water in the wash water supply pipe 103 is maintained at the water pressure of the tap water source 101. Due to the flow into the water tank 105 of the flush toilet, the empty seat is filled with clean water and the clean sewage of the clean sewage reservoir 201 supplied from the water supply source (101).

At this time, the joint pipe 203 connecting the water supply pipe 102, the clean sewage discharge pipe 205, and the washing water supply pipe 103 has a 'T' shape as shown in FIG. 2, and the water supply pipe 102 and the washing water supply pipe ( 103 is connected in a straight line and the clean sewage discharge pipe 205 is connected in a direction perpendicular to the water supply pipe 102 and the washing water supply pipe 103.

In addition, a nozzle 204 is formed in the joint of the water supply pipe 102 toward the joint of the washing water supply pipe 103 so that the tap water has a rapid flow rate and a strong pressure.

The fast flow rate and strong pressure of the tap water passing through the nozzle 204 causes a collision between the clean sewage flowing from the clean sewage reservoir 201 and the inside of the joint pipe 203, and the tap water and the clean sewage are mixed to wash the water supply pipe 103. It flows into the water tank 105 of the flush toilet.

That is, when the float valve 106 in the water tank 105 of the flush toilet is opened as shown in FIG. 3, a small nozzle having a water pressure higher than that of the clean sewage filled in the clean sewage water tank 201 is formed in the joint pipe 203. Fast flowing high pressure water flows through the pipe 203 through the (204).

When the high-speed fast water flows out, the joint of the clean sewage reservoir 201 and the inside of the clean sewage discharge pipe 205 become negative pressure so that the check valve 202 is opened, and then the clean sewage reservoir 201 is stored. The sewage flows into the joint pipe 203, and the clean sewage again collides with the fast and high pressure water supply and is pushed toward the reservoir 105 of the flush toilet.

When the washing water is sufficiently filled in the water storage tank 105 of the flush toilet, the float valve 106 is closed, and since the washing water supply pipe, the fitting pipe 203 and the water supply supply pipe all become constant at the water pressure of the water source 101, the water supply source 101 The check valve 202 installed at the side of the clean sewage tank 201 having a lower water pressure than the lateral side is closed to supply clean sewage to the water storage tank 105 of the flush toilet without additional power.

It is simple, convenient and available to recycle clean sewage using water pressure of existing water supply without saving resources and additional power device by recycling sewage generated in building toilets in a place where water resources are scarce. It can be used hygienically because it has the effect of disinfecting clean sewage with residual chlorine in tap water.
