Description

Flush-type water-saving toilets {A TOILET BOWL FOR ECONOMIZATION OF WATER}

The present invention relates to a flush water toilet, and more particularly, by washing down the feces in the toilet by the pressure of the air together with the washing water, it is possible to reduce the amount of washing water, to clean more cleanly without debris, drainage It is related with a flush toilet to prevent the occurrence of odor by installing an on-off valve in the.

In recent years, as environmental protection and resource saving movements become social problems, it is important to save industrial water used in factories, as well as to save domestic water used at home. It is becoming important to save money.

Therefore, as a method of saving water in the toilet as described above, a method of saving the amount of water flowing out of the toilet by reducing the amount of water in the toilet water tank has been developed, and this method saves living water such as tap water discharged to the toilet. It is recognized as a preferred method in that it can be.

Among these toilets, as shown in FIGS. 1 and 2, the toilets of the recent years are commonly used flush toilets to wash down the feces by the gravity of the water, the flush toilet 10 is a water tank for storing water ( 12), and the toilet unit 24 which the user sits and looks at the side.

The water tank 12 is filled with the washing water 17 used to wash down the excrement, and is provided with a drain valve 16 for opening and closing the drain hole 20 formed in the bottom surface, this drain valve 16 ) Is made of a structure installed to be interlocked with the handle lever 14 and the connection chain 18 exposed to the outside.

In addition, one side is provided with a pipe 15 for supplying the washing water 17 therein.

Meanwhile, the toilet 24 includes a predetermined amount of storage water 26, and is divided into a first drain 22 and a second drain 28 by the guide 19, and the first drain 22. A plurality of water holes 34 are formed at the bottom of the rim 32 through which the washing water 17 has passed, and a jet hole 36 is formed at the tip side of the rim 32.

Therefore, when operating the handle lever 14 provided on one side of the water tank 12 in order to wash the feces in the toilet, the connection chain 18 connected to the handle lever 14 rises in the direction of the arrow water tank 12 The drain valve 16 closing the drain hole 20 formed in the bottom surface of the tank is opened so that the washing water 17 inside the water tank 12 is gravity-powered by the first drain 22 of the toilet 24. Will pass).

In this way, a part of the washing water 17 passing through the first drain passage 22 flows out into the water holes 34 formed at the bottom of the rim 32, and a part of the washing water 17 passes through the jet hole formed at the front end side of the rim 32. 36 is injected into the jet and discharged through the drain 30 through the second drain passage 28 bent along with the excretion contained in the storage water 26.

In this case, the storage water 26 filled in the toilet bowl 24 as described above is also drained in the arrow direction together with the excrement.

Accordingly, the washing water 17 stored in the water tank 12 is operated by operating the handle lever 14 provided on one side of the water tank 12 in the state of viewing the side of the toilet 24. By being injected into the water hole 34 and the jet hole 36, the storage water 26 of the toilet bowl 24 is discharged to the septic tank through the second drain 28 and the drain port 30, and thus the storage water When 26 is discharged together with the stool, the toilet 24 accumulates again with the wash water and accumulates in the storage water.

However, the flush toilet having the structure as described above, in order to wash the toilet in the state seen in the water tank must always be filled with the washing water, the drain valve is simply configured to open and close by the handle lever bar, in the water tank Since the washing water is discharged through the drain hole at one time, the washing water is consumed a lot and there is an uneconomic problem.

In addition, since the wash water in the water tank is discharged to the toilet part through the water hole, the jet hole, and the first drainage at once, if the waste residue adheres to the toilet part, it is not properly discharged and remains in the toilet part, causing unsanitary problems. There was a case.

Thus, the present invention has been made in order to solve the above problems, by washing down the feces in the toilet by the pressure of the air with the washing water, it is possible to reduce the amount of the washing water, and to clean more cleanly without residue The purpose of the present invention is to provide a flush water-saving toilet in which a shutoff valve is installed in the drainage to prevent odors.

In addition, a blocking plate 118 for opening and closing the reservoir 112 is slidably installed. As illustrated in FIGS. 3A and 3B, the blocking plate 118 is provided with a storage tank 112 and a non-storage tank ( It is composed of a blocking plate 120 to slide on the receiving groove 134 formed in the shielding film 132 to block 114, blocking the reservoir 112, and a rack gear portion 124 to slide.

On the other hand, guide rails 126 for guiding the blocking plate 120 of the blocking plate 118 are formed on both side surfaces of the reservoir 112.

The rack gear part 124 of the blocking plate 118 is engaged with the pinion gear 128 and interlocked, and the pinion gear 128 is driven and rotated in reverse according to an electrical signal of a controller (not shown). 130).

Therefore, the control unit applies this signal to the drive motor 130 according to a user's operation of the switch means (not shown), so that the pinion gear 128 interlocks as the drive motor 130 rotates forward and backward. When the gear unit 124 slides forward and backward, the blocking plate 120 of the blocking plate 118 opens and closes a predetermined height position of the storage tank 112.

On the other hand, the butterfly valve 140, which is also opened and closed in accordance with the electrical signal is installed on the front end side of the drain passage 138 communicated with the reservoir 112, the reservoir 112 in accordance with the opening and closing of the butterfly valve 140. The storage water 116 therein is discharged to the drain 138.

The butterfly valve 140 can be more reliably shielded from the storage water 116 by being installed at the tip inlet side of the drainage passage 138 that is bent in a substantially inverted 'c' shape, that is, at the horizontal portion of the drainage passage 138. In addition, maintenance is easy in case of failure.

In addition, an injection nozzle 142 is formed at a lower position of the blocking plate 120 of the blocking plate 118 at one upper side of the reservoir 112, and the injection nozzle 142 is an air supply pipe 144. ) And a washing water supply pipe 146, and a diverter valve 148 is provided at the branch point to selectively open and close the air supply pipe 144 and the washing water supply pipe 146.

For reference, the injection nozzle 142 is installed in a direction opposite to the tip inlet side of the drainage passage 138, and the storage water 116 is more easily drained by the air injected through the injection nozzle 142. It is desirable to discharge through).

The air supply pipe 144 is connected to the air tank 102, the washing water supply pipe 146 is not shown, but is directly connected to the water pipe.

On the other hand, the drive motor 130 connected to the pinion gear 128, the butterfly valve 140 installed in the drainage passage 138 and the switching valve 148 provided at the branch point of the air supply pipe 144 and the wash water supply pipe 146 All are electrically connected to the control unit, the control unit is electrically connected to the switch means that can be selectively installed on the outside of the water tank 102 or the toilet unit 110.

Referring to the use method and the operating state of the flush toilet (100) made of a structure as described above are as follows.

First, in the flush water-saving toilet 100 according to the present invention, the blocking plate 120 of the blocking plate 118 is always kept open, the butterfly valve 140 is installed on the front end of the drain passage 138 It will remain closed.

In such a state, after the user looks at the side of the air tank 102 and the toilet unit 110 by operating the switch means selectively installed may be to drain the storage water in the reservoir (112).

That is, when the switch means is operated and drained, a signal according to this operation is applied to the control unit, and the control unit applies a rotation signal to the drive motor 130, and accordingly the pinion connected to the drive motor 130. As the gear 128 rotates, the rack gear part 124 meshed with the pinion gear 128 is advanced, so that the blocking plate 120 formed integrally with the rack gear part 124 is provided with a guide rail 126 and a shielding film. It slides to the storage tank 112 along the receiving hole 134 of 132, and this storage tank 112 is closed.

At the same time, when a certain time elapses while the blocking plate 120 of the blocking plate 118 blocks the reservoir 112, the butterfly valve 140 is opened, and the switching valve 148 is a washing water supply pipe ( 146 is shielded and an operation signal is applied to the air tank 102 to allow high pressure air through the air supply pipe 144 to be injected into the reservoir 112 through the injection nozzle 142.

Therefore, the storage water 116 stored in the reservoir 112 is swirled by the high pressure air injected through the injection nozzle 142 as described above, the drainage passage 138 as the butterfly valve 140 opens. It will be discharged to the septic tank through.

In this case, as described above, the residues of the sides of the storage tank 112 and the like caused by the vortex of the storage water 116 by the high pressure air are wiped clean, the hygienic effect is exerted.

As such, when the storage water 116 in the reservoir 112 is discharged and a predetermined time elapses, the control unit again applies a blocking signal to the butterfly valve 140 to shield the drainage passage 138, and at the same time, switching An actuation signal is also applied to the valve 148 to shield the air supply pipe 144, and an actuation signal is applied to an on / off valve (not shown) installed on the water pipe side, such that water through the water pipe is sprayed with the washing water supply pipe 146. It is supplied to the reservoir 112 through the nozzle 142.

In this case, the butterfly valve 140 installed at the tip inlet side of the drain passage 138 is kept in a shielded state, so that only a small amount of washing water capable of blocking odor is filled in the storage tank 112.

At the same time, the control unit applies a reverse rotation signal to the drive motor 130 so that the pinion gear 128 connected to the drive motor 130 is rotated, so that the rack ear unit 124 meshed with the pinion gear 128 is reversed. The blocking plate 120 integrally formed with the rack gear part 124 is slid into the storage tank 114 along the receiving hole 134 of the guide rail 126 and the shielding film 132.

Therefore, the blocking plate 118 is to maintain the open state.

In the meantime, the toilet 110 is formed at a predetermined height of the shielding membrane 132 partitioning the storage tank 112 and the non-storage tank 114 to seal the receiving hole 134 to guide the slide plate 118 when sliding. The member 136 is provided to prevent the storage water 116 in the reservoir 112 from leaking into the non-reservoir 114.

For reference, the present invention has been described with an example that the air tank 102 is installed on one side of the non-storage tank 114, an air tank may be installed in the internal space of the non-storage tank 114, In this case, of course, the present invention can be used.

As described above, according to the flush water-saving toilet of the present invention, a reservoir for storing the washing water in the toilet bowl is formed, and is discharged while generating a vortex by the high-pressure air at the time of discharge in the mixed state of the storage water. As a result, a small amount of washing water is used, and there is an economic benefit of water saving. In addition, there is a hygienic effect of cleaning the residue of the stool that is buried on the inner surface of the storage tank.

In addition, the odor from the septic tank is prevented from being discharged to the outside by the butterfly valve provided at the tip side of the drainage passage, thereby providing a more hygienic toilet bowl.
