Abstract
A direct water typed auto-flushing device for toilets is disclosed. The device includes a flush valve, which guides washing water from a water supply to a bidet tank and an actuating unit, and discharges the washing water into a toilet so as to dispose of excrement therein. A sensor is mounted to the underside of a bidet seat, and determines whether excrement is urine or feces according to a user sensing time. An actuating unit opens a solenoid valve and drains washing water, stored in a pressure chamber of the flush valve, through a drain hose into the toilet, thus disposing of excrement in the toilet using washing water fed from a water supply, according to the result of detection by the sensor. The device simplifies a construction by which washing water is fed through the water supply to the bidet tank and the pressure chamber.
Description
- 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.
- Recently, as cultural standards are raised, a restroom is undergoing many changes so that it can be used hygienically and conveniently. In a restroom of a building or public facility that many people use is installed a drain valve, which controls the supply of washing water so as to dispose of excrement.
- When a
lever 11 of thedrain valve 10, which is installed in a toilet, is pressed, as shown inFIGS. 1 and 2 , thelever 11 compresses aspring 11′, and apressure rod 11 a presses adischarge control rod 21 of apiston 20. Further, thedischarge control rod 21 compresses aspring 21′, while it is on an incline. Simultaneously, adischarge hole 22 is opened, so that washing water is discharged from apressure chamber 30 through the discharge hole. - When the washing water stored in the pressure chamber is discharged through the
discharge hole 22, the pressure in thepressure chamber 30 is rapidly reduced. Simultaneously, thepiston 20 is moved up along the inner surface of avalve body 12 by the pressure of washing water fed through a water pipe, and a flushingpipe 13 is opened. The washing water, which is fed from a water supply to the open flushingpipe 13, is discharged into the toilet, and thus disposes of excrement. - Further, when pressing force is released from the
lever 11 of thedrain valve 10, thepressure rod 11 a is restored by the restoring force of thespring 11′, and thedischarge control rod 21 of thepiston 20 is restored by the restoring force of thespring 21′. At this time, thedischarge hole 22 is closed, and some of the washing water fed from the water supply is fed through afilter net 23 and aninlet 24 of thepiston 20 to thepressure chamber 30. - By the washing water fed into the
pressure chamber 30, the water pressure in thepressure chamber 30 is increased, and thepiston 20 is pressed. Thepiston 20 moves down along the inner surface of thevalve body 12, thus closing the flushingpipe 13. Thereby, the supply of washing water from the water pipe is blocked. In this state, the drain valve waits for a subsequent operation. - 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. However, 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.
- Further, when the lever is pressed by the foot, an impact is applied to the lever, so that internal parts of the lever may be damaged. As the internal parts are damaged, washing water leaks out, thus wasting the washing water. Further, it is complicated to replace a damaged part with a new one, so that maintenance is difficult.
- 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.
- In order to solve the problems, Korean U.M. Registration No. 262169, which is entitled Automatic flush valve for toilets, has been proposed.
- As shown in
FIGS. 3 and 4 , theautomatic flush valve 40 for toilets, which was previously registered, determines whether a user's excrement is urine or feces, according to the time detected by an optical sensor 31. If asolenoid diaphragm valve 42 is actuated, thesolenoid diaphragm valve 42 moves up and opens apath 43 which communicates with apressure chamber 30 of adrain valve 10. Simultaneously, washing water stored in thepressure chamber 30 is discharged through thepath 43 to a flushingpipe 13, so that pressure in thepressure chamber 30 is abruptly reduced. - At this time, by the pressure of washing water fed from a water pipe, the
piston 20 is moved up along the inner surface of avalve body 12. Simultaneously, the flushingpipe 13 is opened and the washing water is discharged through the flushing pipe to a toilet, thus disposing of excrement. A proper amount of washing water, which is set depending on whether urination or defecation occurs, is discharged for a set operation time of thesolenoid diaphragm valve 42, to thus dispose of excrement. - Further, when the set operation time of the
solenoid diaphragm valve 42 has passed, thesolenoid diaphragm valve 42 moves down, thus closing thepath 43 which communicates with thepressure chamber 30 of thedrain valve 10. At this time, some of the washing water fed from a water supply flows through afilter net 23 and aninlet 24 of thepiston 20 into thepressure chamber 30. - By the washing water fed into the
pressure chamber 30, the water pressure of thepressure chamber 30 is increased, and simultaneously thepiston 20 is pressed. Thepiston 20 moves down along the inner surface of thevalve body 12, thus closing the flushingpipe 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. However, after a main water supply valve in a building is closed, 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. Further, since the main water supply valve is kept closed, it is impossible to use washing water in the building during the installation period. Furthermore, since the construction of internal parts is complex, assembly is complex and the manufacturing cost is high. Therefore, economic efficiency is low.
- Meanwhile, power that is supplied to the optical sensor uses a battery. However, when the battery is exhausted, and a user is thus not detected by the optical sensor, the conventional problems are not solved. Further, toilets installed in a restroom vary with respect to the number of uses and the time for replacement of a battery. Thus, it is virtually impossible for a manager to determine the exact replacement time and replace the battery with a new one, so that maintenance is difficult.
- Further, in the case of installing the automatic flush valve for toilets which was registered previously in a bidet, the bidet and the flush valve must be coupled to each other via a hose. In order to mount the hose to the flush valve, a hole must be drilled in a predetermined portion of the flush valve. However, residue may be produced because of the drilling process. It is difficult to get rid of the residue. Moreover, in the case where 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. Thus, the conventional flush valve is problematic in that the work process is complicated.
- Further, 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.
- Further, 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. When the washing water is fed into the pressure chamber through the filter net provided at a predetermined position on the piston, the piston moves down. However, 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.

- When the present invention is applied in practice, the addition or elimination of parts is possible.
- First, as shown in
FIG. 6 , apressure rod 11 a, aspring 11′, and alever 11 are mounted to a mountinghole 12′, which is formed horizontally through thevalve body 12 of theflush valve 100. In this state, thepiston 20, which is mounted such that the circular filter net 150 surrounds theinlet 24 of the piston, is seated in thevalve body 12. Next, thesupply guide unit 110 is seated on the upper portion of thevalve body 12, with theheight adjusting member 114 fastened to the lower end of thefastening hole 113 of thesupply guide unit 110. - The circular filter net 150 is mounted to surround the outer circumference of the
piston 20, thus safely guiding the vertical movement of thepiston 20 and preventing interference with the inner circumference of thevalve body 12. - The lower end of the
guide body 111 accommodates the upper end of thevalve body 12. At this time, the internal threadedpart 162 of thefastening part 160, which is formed on the inner circumference of the lower end of thesupply guide unit 110, is on the same line as the external threadedpart 161 of thefastening part 160, which is formed on the outer circumference of the upper end of thevalve body 12. When theguide body 111 of thesupply guide unit 110 is rotated in one direction, the internal threadedpart 162, which is formed on the inner circumference of thesupply guide unit 110, engages with the external threadedpart 161 formed on the outer circumference of thevalve body 12. Thereby, thesupply guide unit 110 is secured to thevalve body 12. - An internal threaded part may be formed on the inner circumference of the upper end of the valve body, while an external threaded part may be formed on the outer circumference of the lower end of the supply guide unit, so that the internal threaded part. engages with the external threaded part.
- As described above, the first ends of the
supply hoses supply guide unit 110. In this state, theplay prevention piece 191 of theplay prevention unit 190 is coupled to the second ends of thesupply hoses supply hoses play prevention piece 191 and the play prevention piece is moved to the first ends of thesupply hoses play prevention ring 192 is coupled to the second ends of thesupply hoses supply hoses play prevention piece 191. - Meanwhile, the
play prevention ring 192 of theplay prevention unit 190 may be coupled to thesupply hoses supply hoses play prevention piece 191. Thereafter, the first ends of thesupply hoses supply guide unit 110. - When the
play prevention unit 190 is located at the first ends of thesupply hoses supply hoses protective body 131 of theprotective unit 130 in such a way as to protrude out of theprotective hole 133. After theplay prevention ring 192 of theplay prevention unit 190 is located at theprotective hole 133, theprotective body 131 of the protective unit: 130 is moved downwards to be seated on theguide body 111 of thesupply guide unit 110. - At this time, one or more
rotation preventing protrusions 172 of therotation preventing part 170, which are provided on the inner circumference of theprotective body 131 of theprotective unit 130, engage with therotation preventing grooves 171, which are radially provided on the outer circumference of theguide body 111 of thesupply guide unit 110, thus preventing the rotation of theprotective unit 130. Further, the inner surface of theprotective body 131 of theprotective unit 130 is in close contact with the upper surface of thefastening hole 113 of thesupply guide unit 110. At this time, thefastening hole 132 in theprotective unit 130 and thefastening hole 113 in thesupply guide unit 110 are positioned along a vertical line. - Here, as shown in
FIG. 7 , since therotation preventing grooves 171 are radially formed on the outer circumference of theguide body 111 of thesupply guide unit 110, theprotective body 131 is rotated at a predetermined angle so as to adjust the position of theprotective hole 133 in theprotective unit 130 relative to therotation preventing grooves 171. In this state, assembly may be executed through the above-mentioned process. - Further, when the inner surface of the
protective body 131 of theprotective unit 130 is seated on the upper surface of thefastening hole 113 of thesupply guide unit 110, thefastening hole 113 in thesupply guide unit 110 and thefastening hole 132 in theprotective unit 130 are placed on the vertical line. After thefastening member 140 is inserted into the fastening holes, the fastening member is rotated in one direction. Thereby, thefastening member 140 is fastened to thefastening hole 132 in theprotective unit 130 and thefastening hole 113 in thesupply guide unit 110. As a result, theprotective unit 130 is secured to thesupply guide unit 110. - The
covering piece 182 is mounted to thedepression 181 of the coveringpart 180, which is provided in the upper surface of theprotective body 131 of theprotective unit 130 so as to isolate thefastening member 140, fastened to the fastening holes 132 and 113 of theprotective unit 130 and thesupply guide unit 110, from the exterior. Thereby, thefastening hole 132 is closed, and thefastening member 140 is hidden so as to be isolated from the exterior. - An advertising description or logo may be printed on the upper surface of the
covering piece 182. Finally, the second ends of the supply hoses :120 and 120′ are connected to thewater tank 52 of thebidet 50 and thesolenoid valve 310 of theactuating unit 300, respectively. Thereby, as shown inFIG. 8 , the installation of the present invention is completed. - The operation of the auto-flushing device, according to the present invention, which is assembled in this way, will be described below in detail.
- First, when a user sits on the
seat 51 of thebidet 50, which is installed in thetoilet 60, the user is detected by thesensor 200. Simultaneously, a user sensing time is measured, so that it is determined whether excrement is feces or urine. - When the user desires to select an anus washing function or a genitalia washing function after defecating, an anus/genitalia washing button of a
manipulation part 50′ of thebidet 50 is pushed. As the anus/genitalia washing button is pushed, adirection conversion valve 53 is rotated to communicate with anozzle 54. Thenozzle 54 is either of an anus washing nozzle or a genitalia washing nozzle. - For example, if the user pushes the anus washing button, warm water stored in the
water tank 52 of thebidet 50 flows through thedirection conversion valve 53, and thereafter, is sprayed through thenozzle 54, namely, the anus washing nozzle, thus washing the anus and the area around the anus. - When washing water is sprayed through the
nozzle 54, which reduces, the level of the washing water stored in thewater tank 52, as shown inFIG. 9 , washing water is fed from the water supply under the control of a water level sensor (not shown), which is provided on the upper portion of thewater tank 52. The washing water flows through thehose insert hole 112 of thesupply guide unit 110 and thesupply hose 120 to thewater tank 52. Simultaneously, the level of the washing water which is supplied to and stored in thewater tank 52 is detected by the water level sensor (not shown). When a proper amount of water has been supplied to the water tank, the supply of washing water is ceased. By repeating these processes, the level of washing water is kept constant. - When the user's anus has been washed through the above-mentioned process and then the user rises from the
seat 51, thesensor 200, mounted to the underside of theseat 51 does not detect the user anymore. Thus, with reference to the user sensing time detected by thesensor 200, it is determined whether excrement is feces or urine. For example, when the user sensing time is 2 minutes or more, it is determined that excrement is feces. Conversely, when the user sensing time is 2 minutes or less, it is determined that excrement is urine. - According to the result detected by the
sensor 200, thesolenoid valve 310 of theactuating unit 300 is opened. At this time, as shown inFIG. 10 , washing water stored in thesupply hose 120′ is discharged through thesolenoid valve 310 to thedrain hose 320. Simultaneously, as shown inFIG. 11 , washing water contained in thepressure chamber 30 of theflush valve 100 is discharged through thehose insert hole 112′ of thesupply guide unit 110, the supply hose 1201, and thesolenoid valve 310 of theactuating unit 300 to thedrain hose 320, and is drained into thetoilet 60. - At this time, the washing water contained in the
pressure chamber 30 is fed to theactuating unit 300, which abruptly reduces the internal pressure of thepressure chamber 30. Further, by the pressure of washing water fed through a water pipe, thepiston 20 is moved up along the inner surface of thevalve body 12. Simultaneously, the flushingpipe 13 is opened. Washing water fed through the water pipe is discharged through theopen flushing pipe 13 to thetoilet 60, thus disposing of excrement in thetoilet 60. - In this case, the kind of excrement is determined by the user sensing time, which is detected by the
sensor 200. A proper amount of washing water, which corresponds to the kind of excrement, is discharged by adjusting the opening time of thesolenoid valve 310 of theactuating unit 300. Thereby, the unnecessary waste of washing water is prevented. - When a preset opening time of the
solenoid valve 310 of theactuating unit 300 has elapsed, so that thesolenoid valve 310 is closed, washing water fed from the water supply is discharged to the flushingpipe 13. Simultaneously, some of the washing water fed from the water supply is filtered by the circular filter net 150 so as to remove contaminants from the washing water. Afterwards, the filtered water is fed through theinlet 24 of thepiston 20 to thepressure chamber 30 and thesupply hose 120′. As the pressure of the washing water stored in thepressure chamber 30 and thesupply hose 120′ increases, the upper surface of thepiston 20 is pressed. - At this time, the
piston 20 is moved downwards along the inner surface of thevalve body 12, and simultaneously the flushingpipe 13 is closed. Thereby, in the state where the supply of washing water from the water supply is blocked, the flushing device waits for a subsequent operation. - Further, when the supply of power to the
bidet 50 is blocked, as shown inFIGS. 12 and 13 , the toilet may be used in a conventional manner using thelever 11 of theflush valve 100. - As described above, the present invention provides a direct water typed auto-flushing device for toilets, which simplifies a construction by which washing water fed from a water supply is supplied to both a water tank of a bidet and a pressure chamber of a flush valve, thus simplifying installation work and shortening a working period.
- Further, the present invention provides a direct water typed auto-flushing device for toilets, in which supply hoses are mounted to a protective hole in a protective unit via a play prevention unit, thus preventing the supply hoses from being damaged, and allowing the installation direction of the supply hoses to be adjusted as desired, therefore providing a good appearance.
- Further, the present invention provides 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 and affording easy maintenance, and which does not use a battery, thus reducing environmental pollution attributable to the battery.
