- Figs. 12 and 13 are views showing the operating state of the auto-flushing device, according to the present invention, when the flushing device is manually operated.
- the present invention relates, in general, to a flush valve for toilets and, more particularly, to a direct water typed auto-flushing device for toilets, which is operated such that washing water, fed from a water supply is guided into a water tank of a bidet and an actuating unit, and, simultaneously, the washing water is discharged into a toilet through a flush valve by the operation of the actuating unit, thus disposing of excrement in the toilet.
- a lever 11 of the drain valve 10 which is installed in a toilet, is pressed, as shown in Figs. 1 and 2, the lever 11 compresses a spring 11', and a pressure rod 11a presses a discharge control rod 21 of a piston 20. Further, the discharge control rod 21 compresses a spring 21', while it is on an incline. Simultaneously, a discharge hole 22 is opened, so that washing water is discharged from a pressure chamber 30 through the discharge hole. When the washing water stored in the pressure chamber 30 is discharged through the discharge hole 22, the pressure in the pressure chamber 30 is rapidly reduced.
- the piston 20 is moved up along the inner surface of a valve body 12 by the pressure of washing water fed through a water pipe, and a flushing pipe 13 is opened.
- the washing water which is fed from a water supply to the open flushing pipe 13, is discharged into the toilet, and thus disposes of excrement .
- the drain valve operated as described above, is constructed so that washing water stored in the pressure chamber is discharged to the flushing pipe by pressing the lever, so that water pressure is reduced, and the piston is moved up along the inner surface of the valve body by the water pressure of the washing water supplied through the water pipe, so that the flushing pipe is opened.
- the drain valve is problematic in that if the lever is dirty, it may be pressed not by the hand but by the foot, or a user may even not flush a toilet after defecating.
- the amount of washing water that is discharged through the drain valve is determined in proportion to the amount of time that the lever is pressed.
- the conventional drain valve is problematic in that the lever may be pressed for too long, so that washing water may be undesirably wasted. Further, an amount of water required to wash away feces is discharged regardless of whether urination or defecation occur, and thus washing water is wasted in the case where a user urinates, and thereby economic efficiency is low.
- the automatic flush valve 40 for toilets determines whether a user's excrement is urine or feces, according to the time detected by an optical sensor 31. If a solenoid diaphragm valve 42 is actuated, the solenoid diaphragm valve 42 moves up and opens a path 43 which communicates with a pressure chamber 30 of a drain valve 10. Simultaneously, washing water stored in the pressure chamber 30 is discharged through the path 43 to a flushing pipe 13, so that pressure in the pressure chamber 30 is abruptly reduced.
- the solenoid diaphragm valve 42 moves dow ⁇ , thus closing the path 43 which communicates with the pressure chamber 30 of the drain valve 10. At this time, some of the washing water fed from a water supply flows through a filter net 23 and an inlet 24 of the piston 20 into the pressure chamber 30.
- the water pressure of the pressure chamber 30 is increased, and simultaneously the piston 20 is pressed.
- the piston 20 moves down along the inner surface of the valve body 12, thus closing the flushing pipe 13, therefore blocking the supply of the washing water from the water pipe. In this state, the flush valve waits for a subsequent operation.
- the automatic flush valve which is operated as described above and was registered previously, is advantageous in that it solves the problems of the prior art.
- the entire flush valve having the solenoid diaphragm valve and the optical sensor must be replaced with a new one, so that a long installation time is required.
- the main water supply valve is kept closed, it is impossible to use washing water in the building during the installation period.
- assembly is complex and the manufacturing cost is high. Therefore, economic efficiency is low.
- the bidet and the flush valve must be coupled to each other via a hose.
- a hole must be drilled in a predetermined portion of the flush valve.
- residue may be produced because of the drilling process. It is difficult to get rid of the residue.
- the flush valve has been installed, the operation of removing the residue is very difficult. That is, after the flush valve is separated from the bidet and the drilling operation is performed, the operation of removing the residue is executed. Thereafter, the flush valve must be mounted to the bidet again.
- the conventional flush valve is problematic in that the work process is complicated.
- the bidet cover when a bidet cover is rotated upwards to use the bidet, the bidet cover is placed in front of the optical sensor, so that it is impossible to sense a user who sits on a seat and performs excretion, and thus the automatic flush valve may not function as desired.
- the piston is moved up and down along the inner surface of the valve body by the water pressure of washing water which is stored in the pressure chamber.
- the piston moves down.
- the piston may not be moved down vertically by the washing water fed through the filter net. In this case, the leakage of washing water undesirably occurs .
- an object of the present invention is to provide a direct water typed auto-flushing device for toilets, which simplifies the construction by which washing water fed from a water supply is supplied through a flush valve to both a water tank of a bidet and a pressure chamber, and by which washing water is drained from the pressure chamber, thus simplifying installation work and shortening the working period.
- Another object of the present invention is to provide a direct water typed auto-flushing device for toilets, in which a supply hose mounted to a flush valve may be installed in a desired direction, thus preventing the supply hose from being damaged, and providing a good appearance.
- a further object of the present invention is to provide a direct water typed auto-flushing device for toilets, in which an actuating unit is operated by power supplied to a bidet, thus being used stably, in addition to affording easy maintenance.
- Yet another object of the present invention is to provide a direct water typed auto-flushing device for toilets, in which whether urination or defecation occurs is determined in response to a user sensing time, and a proper amount of washing water is discharged according to whether urination or defecation occurs, thus saving washing water which might otherwise be discharged unnecessarily.
