Description

  The present invention relates to a filth carrier system that conveys filth from toilets installed in parallel through a common drain pipe.

In recent years, toilet bowls can be washed with a small amount of washing water due to improved toilet performance.
On the other hand, the drainage pipe connected to the toilet bowl, i.e. the drainage pipe connected to the toilet outlet through the connecting pipe and transporting filth and washing water from the toilet bowl, when the amount of washing water discharged from the toilet bowl decreases, The ability to transport filth is affected.
Thus, if the conveying capacity is greatly reduced, there is a concern that clogging with dirt will occur in the drain pipe.

The amount of water used for flushing toilets is set to the amount of water required to transport waste through the drain pipe as well as draining waste from the toilet, but the toilet is a water-saving toilet. As the amount of water becomes smaller, the amount of water transported in the drainage pipe becomes smaller, and in the case of a normal toilet that is not water-saving, the deterioration of the performance of transporting filth in the drainage pipe has become a problem.
In particular, such a problem is a big problem in toilets and public toilets of buildings where toilets are installed in a row and filth from each toilet is transported by a common drain pipe.

The filth carrier system which made such a point a solution subject is disclosed by the following patent document 1. FIG.
However, in the device disclosed in Patent Document 1, when the number of times the downstream toilet is used reaches a predetermined number, a large amount of washing water is flowed through the upstream toilet to transport the filth in the drain pipe. However, it is not enough from the viewpoint of saving water.

  The present invention has been made for the purpose of providing a filth carrier system capable of enhancing the filth carrier capacity in a drain pipe while saving water in the background as described above.

Thus, according to the first aspect of the present invention, a common drain pipe is connected to the outlets of a plurality of continuous toilets, and filth and washing water discharged from each toilet bowl are caused to flow into the drain pipes to pass through the drain pipes. In the waste transport system configured to transport, the information transfer means for transmitting information on the use of each toilet is provided between the toilets, and the toilets are cleaned based on the received information. Provided with a control unit for controlling, for the purpose of transporting filth that has flowed upstream according to the cleaning timing of the toilet on the downstream side of the drainage pipe and when the waste from the downstream toilet is discharged into the drainage pipe wash water is so as to reach the soil material, characterized in that without such flowing the wash water to the drainage pipe from the water supply means supply the water directly to the toilet or the drain pipe of the upstream side.

According to a second aspect of the present invention, a common drain pipe is connected to the outlets of a plurality of continuous toilets, and the waste and washing water discharged from each toilet are caused to flow into the drain pipe and transported through the drain pipe. In the waste transport system according to the present invention, there is provided information transmitting means for transmitting information on the use of each toilet bowl between the toilet bowls, and control for controlling the toilet flushing operation based on the received information for each toilet bowl. When the sewage from the toilet on the downstream side is discharged into the drainpipe in accordance with the cleaning timing of the toilet on the downstream side of the drainpipe, the cleaning water for transporting the filth that has flowed upstream is as is flowing part following the connecting pipe of the downstream side toilet in drainpipe, to flow the cleaning water to the drainage pipe from the water supply means supply the water directly to the toilet or the drain pipe of the upstream side Octopus The features.

According to a third aspect of the present invention, a common drain pipe is connected to the outlets of a plurality of continuous toilets, and the waste and washing water discharged from each toilet are caused to flow into the drain pipe and conveyed through the drain pipe. In the waste transport system according to the present invention, there is provided information transmitting means for transmitting information on the use of each toilet bowl between the toilet bowls, and control for controlling the toilet flushing operation based on the received information for each toilet bowl. It is characterized in that the washing water is made to flow sequentially from the toilet on the upstream side.

According to a fourth aspect of the present invention, in the third aspect , the amount of flush water is sequentially increased from the toilet on the upstream side.

Effects and effects of the invention

As described above, according to the first aspect of the present invention, in the filth transport system for transporting the filth from the toilets installed in a shared manner through a common drain pipe, the information transmission for transmitting information on the use of the toilet between the toilets In addition to providing means, a control unit for controlling the washing operation is provided for each toilet, and cleaning for transferring filth from the upstream toilet or water supply means to the drain pipe according to the cleaning timing of the toilet on the downstream side of the drain pipe It was designed to make water flow.
Here, information on the use of the toilet includes, for example, the number of uses, use time, seating on and taking off the toilet, cleaning the toilet, the number of times the cigarette is used, the number of times the doors such as booths where the toilet is installed, and the water supply pressure Etc.
Further, the information transmission means for the usage information may be configured to include infrared rays, radio waves (including microwaves) and their transmission / reception units, or may be performed by wire.

According to the present invention, even when the toilet bowl is a water-saving toilet bowl, that is, when the amount of washing water is small, the waste discharged into the drain pipe is reduced by the amount of washing water from the toilet bowl and the washing water from the upstream side. The inside of a drain pipe can be conveyed, the conveyance capacity in a drain pipe can be improved effectively, maintaining water saving, and the clogging of filth in a drain pipe can be prevented favorably.
When flush water is allowed to flow into the drain pipe from the upstream toilet, this can be performed regardless of whether the upstream toilet is used.

In the present invention, when the wash water that has flowed to the drain pipe on the upstream side reaches a position corresponding to the toilet on the downstream side, the momentum of the flow is strong due to the drainage gradient of the drain pipe. Water has a large transport capacity based on the flow momentum for the amount of water, and the waste discharged from the downstream toilet into the drain pipe is good along with the wash water from the downstream toilet that was discharged at the same time. Transport to.
In other words, compared with the case where the amount of washing water from the toilet used on the downstream side is increased to increase the conveying capacity in the drainpipe, the amount of washing water from the upstream side is equivalent to the increase in the smaller amount of water because of the strong momentum of the washing water. Can be provided.
For this reason, according to this invention, the quantity of water for filth conveyance can be decreased, and the objective of water saving can be achieved.

In the present invention, in filth it is discharged to the drainage tube timing from the downstream side of the toilet bowl, flush water which flowed on the upstream side to flow to drain the wash water to reach the waste.
By doing in this way, since the washing water which flowed from the upstream side hits the filth in the drain pipe with a strong momentum, the filth can be transported with a strong transport capability.
In order to allow flushing water to flow at such timing, for example, when a toilet cleaning operation is performed by a user on a downstream toilet, a flush valve that directly supplies water to the upstream toilet or drain pipe, etc. This is realized by transmitting information to the water supply means and slightly delaying the actual start of washing in the downstream toilet.

In the present invention, for example, assuming that the amount of flushing water in the toilet bowl is 8 L (liters) in anticipation of the transfer of filth in the drainpipe (5 L is the amount of water necessary to drain the sewage from the toilet bowl into the drainpipe, 8L, which is 3L added to this, is the amount of water required for transport), the amount of water required as wash water in the downstream toilet is 5L, and the remaining 3L can be flowed as wash water from the upstream side.
In this case, the conveyance capacity in the drain pipe can be made higher than when the amount of washing water is 8L. This is because the transport capacity of the water for 3 L is enhanced by the momentum flowing through the drain pipe.

On the other hand, since the washing water from the upstream side has a momentum in the drain pipe and has a high conveying capacity, for example, it can be made to flow only 1 L.
Even in this case, it is possible to obtain a conveyance capacity equivalent to that when the toilet flushing water amount is 8 L.
In this case, since the amount of water used is reduced, it is possible to save water more than in the past.

Meanwhile claim 2, as when the dirt from the downstream side of the toilet is discharged into the drainage pipe cleaning water from the upstream side flows a part following the connecting pipe on the downstream side of the toilet in the drainage pipe, upstream is that no way flow of wash water from.
In the case of this Claim 2 , since the filth from the toilet on the downstream side is discharged to the place where the wash water is already flowing in the drain pipe, the filth is discharged when the wash water is not flowing in the drain pipe Compared to the above, the carrying capacity can be increased, and the carrying capacity of filth can be effectively increased with a small amount of washing water.

Next, the third aspect of the present invention is configured so that the washing water is sequentially flowed from the toilet on the upstream side.
In this case, it is preferable that the flush water from each toilet in the drain pipe flows at a timing such that it accumulates as it goes downstream.
According to the third aspect , as the filth flows downstream in the drainage pipe and the amount thereof increases, the wash water is sequentially supplied from each toilet from the upstream side to the downstream side in stages. Since it flows in the drain pipe, it is possible to effectively carry filth in the drain pipe.

In this case, the amount of washing water can be increased sequentially from the upstream toilet (claim 4 ).

Next, embodiments of the present invention will be described in detail with reference to the drawings.
In FIG. 1, 10 is a toilet bowl booth provided in series, and toilets (Western style toilets) 1, 2, 3, and 4 are installed therein.
A water supply pipe 12 is common to the toilets 1 to 4, and is connected to the toilets 1 to 4 through a communication pipe 14.
Each toilet 1 to 4 performs toilet flushing by discharging flush water into the toilet based on the water supplied from the water supply pipe 12.
In FIG. 1, 16 is a toilet cleaning device comprising an electromagnetic flash valve device or the like, and is provided corresponding to toilets 1-4.
18 is a drainage pipe common to each toilet 1-4, and is connected to the discharge port of each toilet 1-4 via the connecting pipe 20, respectively.

Reference numeral 22 denotes a transmission / reception unit provided in each of the toilets 1 to 4, and these transmission / reception units 22 communicate information on the use of the toilet with other toilets 1 to 4, for example, the number of times used, the usage time, and the toilet Information such as seating, seating, toilet cleaning, the number of times the cigarette is used, the number of times the toilet booth 10 where the toilet is installed, the number of times the door is opened and closed, and the water supply pressure are sent and received.
Each of the toilets 1 to 4 is also provided with a control unit 24 that controls the operation of the toilet cleaning device 16 based on a reception signal in the transmission / reception unit 22.

FIG. 2 shows an example of the filth transport using the filth transport system of FIG.
In this example, the flushing water, for example, the flushing water from the toilet 1 at the timing when the filth from the downstream toilet bowl, for example, the toilet bowl 3 is discharged into the drain pipe 18, reaches the filth. This is an example in which a cleaning operation is performed in the toilet 1.
Specifically, when the use of the toilet bowl 3 is finished, a use end signal of the toilet bowl is transmitted from the transmission / reception unit 22 provided in the toilet bowl 3 based on an operation for starting toilet flushing by the user, and this signal is sent to the toilet bowl 1. Is received by the transmitter / receiver 22.

In the toilet bowl 3, the actual toilet bowl cleaning operation is not performed immediately, and the cleaning operation is started with a slight time difference.
On the other hand, on the toilet 1 side, after the signal is received by the transmission / reception unit 22, the toilet cleaning device 16 is immediately opened by the control unit 24, and the cleaning operation of the toilet 1 is started.
At this time, the washing water discharged into the toilet 1 is caused to flow to the drain pipe 18 through the connecting pipe 20.
The washing water that has flowed into the drain pipe 18 flows down the drain pipe 18 to the downstream side under the drain gradient of the drain pipe 18.

On the other hand, on the toilet 3 side, toilet cleaning is performed with a slight delay, that is, the toilet cleaning device 16 on the toilet 3 side is opened under the control of the control unit 24, and flush water is discharged into the toilet 3, so that the toilet 3 is cleaned. Done.
At this time, the filth in the toilet bowl 3 is discharged into the drain pipe 18 together with the washing water.
Then, at the timing when the filth is discharged into the drain pipe 18, the wash water that has just flowed from the toilet 1 on the upstream side reaches the filth, and the filth discharged into the drain pipe 18 is washed from the toilet 1. Water and toilet flushing water that has flowed out of the toilet bowl 3 are transported downstream as transport water.

  According to this example, even when the toilet bowl is a water-saving toilet bowl, that is, when the amount of washing water is small, the waste discharged from the drain pipe 18 is washed with the washing water from the upstream toilet bowl 1 into the washing water of the toilet bowl 3. Soil can be transported in the drain pipe 18 with the combined amount of water, the transport capacity in the drain pipe 18 can be effectively enhanced while maintaining water saving, and the clogging of filth in the drain pipe 18 can be satisfactorily prevented. be able to.

Further, when the washing water flowed from the upstream toilet 1 to the drain pipe 18 reaches a position corresponding to the downstream toilet 3, the flow of water becomes stronger due to the drainage gradient of the drain pipe 18. Therefore, the wash water from the toilet 1 has a large conveying capacity based on the flow rate for the amount of water, and the waste discharged from the downstream toilet 3 into the drain pipe 18 was discharged at the same time. Convey well with the wash water from the toilet 3 on the downstream side.
In other words, compared with the case where the amount of washing water from the toilet 3 used on the downstream side is increased to increase the conveying capacity in the drainpipe 18, the amount of water is smaller due to the strong momentum of the washing water from the toilet 1. By increasing, it is possible to transport filth with the same transport capacity.
For this reason, according to this example, the amount of water for conveying filth can be reduced, and the purpose of saving water can be achieved.

In this example, the wash water is allowed to flow through the drain pipe 18 so that the wash water from the upstream side reaches the filth at the timing when the filth from the downstream toilet 3 is discharged into the drain pipe 18. Since the washing water flowing from the side strikes the filth in the drain pipe 18 with a strong momentum, the filth can be conveyed with a strong conveyance capability.
In this case, the amount of water used can be reduced, and water can be saved compared to the conventional case.

In this example, the toilet 3 is actually used, and the cleaning water of the toilet 1 upstream is supplied to the waste from the toilet 3, but the cleaning water is discharged from the toilet 2 regardless of whether it is used or not. You may make it flow in 18.
Alternatively, when the toilet 4 is used, it is possible to cause the flush water to flow into the drain pipe 18 from any one or a plurality of the toilets 1, 1 and 2 on the upstream side.

  In the above example, prior to the toilet flushing of the downstream toilet bowl, for example, the downstream toilet bowl 3, the flush operation of the upstream toilet bowl 1 is performed, and the toilet bowl is discharged at the timing when the filth from the toilet bowl 3 is discharged to the drain pipe 18. This is a case where each toilet is cleaned so that the cleaning water from 1 reaches the filth, but instead of the cleaning operation in the toilet 1, for example, as shown in FIG. It is also possible to allow the flush water to flow through the drain pipe 18 by the flush valve device 28 provided there. This also applies to the following.

Further, for example, before the filth from the toilet bowl 3 is discharged to the drain pipe 18, the toilet flushing water or the water supply pipe 12 is directly supplied into the drain pipe 18 from the upstream toilet 1 or the flush valve device 28. When the filth from the toilet bowl 3 is discharged into the drain pipe 18, the part of the drain pipe 18 following the connecting pipe 20 of the toilet bowl 3, that is, the part into which the filth flows into the drain pipe 18. As shown in the drawing, each toilet can be cleaned or water supplied from the flush valve device 28 can be supplied.
In this case, since the filth from the toilet 3 on the downstream side is discharged to the place where the washing water is already flowing in the drain pipe 18, the filth was discharged when the washing water is not flowing in the drain pipe 18. Compared to the case, the conveying ability can be increased, and the conveying ability for filth can be effectively increased with a small amount of washing water.

Next, FIG. 3 shows an example in which the toilet flushing water is made to flow to the drain pipe 18 sequentially from the upstream toilet.
Specifically, first, the toilet 1 starts a cleaning operation, and information on the start of the cleaning operation in the toilet 1 is transmitted by the transmission / reception unit 22.
This signal is also transmitted to each toilet 2, toilet 3 and toilet 4, but when this signal is received, the toilet 2 starts the cleaning operation following the toilet 1, and at the same time, the toilet 2 starts the cleaning operation. The data is transmitted from the transmission / reception unit 22.
In response to this, the toilet 3 starts a cleaning operation. In addition, the toilet 3 transmits information on the start of the cleaning operation in the toilet 3 from the transmission / reception unit 22 from the transmission / reception unit 22.
And the toilet 4 receives this signal by the transmission / reception part 22, and starts toilet bowl washing | cleaning operation | movement based on this.

According to this example, when filth flows in the drain pipe 18 to the downstream side, the wash water is sequentially flowed into the drain pipe 18 from each toilet from the upstream side to the downstream side. It is possible to effectively carry the filth inside.
In the embodiment of FIG. 3, the amount of washing water can be set so that the toilet 2 is more than the toilet 1, the toilet 3 is more than the toilet 2, and the toilet 4 is more than the toilet 3.
Here, the sequential cleaning operation of the toilet from the upstream side in FIG. 3 can be performed, for example, once a day or once every half day.

  Although the embodiments of the present invention have been described in detail above, these are merely examples, and the present invention is not limited to the case where urinals are installed in a row, but also in the case where urinals are installed in a row or large. The present invention can be configured in various forms without departing from the gist of the present invention, for example, when the toilet bowl and the urinal are installed in a simultaneous state.
