Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a circulating toilet used in a portable portable toilet, and in particular, to a circulating toilet used for a portable portable toilet. Wi that can replenish water
This relates to a water replenishment method for circular toilets.

[Conventional technology]

BACKGROUND ART Conventionally, simple toilets that store human waste in a tank have been widely used in places where there is no sewage system or in toilets on public transportation. In this case, there is no sewage facility, so deodorizers and disinfectants are added to the seat ring stored in the tank, and only the water from this human waste is pumped up and discharged into the toilet bowl, where it is circulated and used as water for cleaning. There were also some types. Such circulation-type simple toilets are already widely used in transportation such as trains and airplanes, and are an extremely common toilet cleaning method today.

In these circulating toilets, it is necessary to collect the seat rings accumulated in the tank and clean the tank at regular intervals or when the transportation vehicle arrives at its destination.
This was to completely empty the MH tank. and,
In order to use the toilet next time, it was necessary to fill the empty tank with water for initial settings.

The initial purpose of water is to provide flushing water even when the toilet is used for the first time after cleaning the tank. If this default water is not filled into the tank, it will not be able to function as a circulating toilet, and water must be replenished immediately after collecting human waste in the pressurized urine tank. This was also to prevent the vestments from sticking to the inner walls of the tank, and to prevent residue from sticking to the filters installed at the suction pump's inlet, making it impossible to use them again.

In such a Wi-covered toilet, it is possible to wash with a jet stream even in places where there is no sewerage system, making it extremely convenient. However, as mentioned above, it has been necessary to collect human waste at regular intervals or each time the vehicle reaches its destination, and then to replenish the water by injecting initial water. For this reason, such i-ring toilets are extremely effective in situations where maintenance workers are always on standby, such as on trains or airplanes, but for example, if you install these i-circulating toilets in the mountains, or If the toilet is set up in a square without water supply facilities, water must be replenished after collecting human waste, making it difficult to fill the toilet tank with a large amount of water. In particular, if the circulating toilet is located far from the water supply, it is necessary to fill a truck or tanker with water and then inject the initial water after collecting human waste, which is extremely troublesome as maintenance work is doubled. there were.

[Problem to be solved by the invention]

As mentioned above, in conventional circulating toilets, two tasks have to be performed: collecting the vestments stored in the toilet tank and filling the initial water supply. This required different maintenance work. For this reason, there was a need to take advantage of the advantage of circulating toilets, which allow the toilet to be flushed even when water and sewage systems are not connected, and to simplify maintenance.

For this reason, even if a circulating toilet is installed in the mountains, riverbeds, or squares where water supply facilities are not available, there is no need for an initial water supply, and maintenance can be completed by simply removing human waste. was awaited.

[Means for solving problems]

In view of the above-mentioned drawbacks, the present invention provides a circulation type toilet in which human waste is stored in a tank and a part of the accumulated human waste is used for cleaning the toilet bowl. After the human waste stored in the feces tank is discharged, the urine stored in the urination tank is transferred to the feces tank, and this urine is used as the initial circulating water used for flushing the toilet bowl. The present invention provides a water replenishment method for a circulating toilet characterized by the following.

[Effect]

In the present invention, urine collected from a urinal is stored in a urine tank, and small stools collected from a urinal are stored separately in the feces tanks. When trying to collect human waste, collect only the human waste in the fecal tank,
After the feces tank is empty, the urine stored in the urine tank is transferred to the feces tank, and this stored urine serves as the initial water.

This eliminates the need for initial water replenishment in circulating toilets, and maintenance after installation is limited to just pumping out the robes in the feces tank. , maintenance can be performed in the same way as conventional household pump-type toilets, making it extremely easy to manage.

Next, the operation of this embodiment will be explained.

First, the temporary toilet 1 is transported by truck or the like to the temporary location where it is to be used, and is installed on the ground etc. When the temporary toilet 1 is installed at the temporary location, the urine tank 12 and the feces tank L3 Although both of the interiors are empty, after installing the temporary toilet 1, initial water is injected from the intake port 22 until the initial water level is located above the filter 18.

After this, a person who wants to use this temporary toilet 1 can enter the temporary toilet 1 through the entrance 2 and close the door 4 to urinate or defecate. Excretion processing can be performed by using the toilet bowl 6 for urine and urine, and by using the urinal bowl 7 for urine. And urination is urinal 6
The urine is collected in the urinal 7 and then passed through the drain pipe 8 to the urine tank 12.
is stored in

Then, after using the toilet bowl 6, the user presses the start switch 28, thereby starting the cleaning operation of the toilet bowl 6. First, start the switch.

The control device 27 is started by pushing the switch 28, and the switching valve 16 is activated.
The pump 20 is operated with the suction pipe 17 and the communication pipe 19 connected. For this purpose, the pump 2o sucks the initial water in the stool tank 13, causes it to flow through the filter 18, suction pipe 17, switching valve 16, communication pipe 19, and discharge pipe 21, and squirts it inside the toilet bowl 6. . Therefore, the filth adhering to the inner periphery of the toilet bowl 6 is flushed out by this jet and collected in the feces tank 13. Note that at this time, by putting chemicals such as deodorants and cleaning agents into the toilet bowl 13, the cleaning efficiency of the toilet bowl 6 can be improved.

Further, urine is collected in the urinal 7 and stored in the urine tank 12 one after another. And urine tank 12
When the urinal is filled to a capacity exceeding the capacity of , the urine flows into the feces tank I3 through the communication hole 14,
The urine A is stored in the urine tank 12 to a position below the communication hole 14.

In this way, when you use the temporary toilet I, the urine tank 1
Urine A is stored in the tank 2, and deep layer B, which is a mixture of excrement and urine and initial IUL water, is stored in the feces tank 13.

When the temporary toilet 1 is used for a certain period of time and more than a predetermined amount of urine B is accumulated in the feces tank 13, a hose is inserted into the intake port 22 using a vacuum car or the like, for example. Pour out all the human waste B inside. As a result, all of the Shobara B in the feces tank 13 is pumped out, and the feces tank 13 becomes empty. Stool tank 1
When all of the human waste B in the tank 3 is discharged, the water level sensor 24 detects that it has been discharged, and a signal is transmitted to the detector 26. Then, the detector 26 transmits the delayed signal to the control device 27 after a predetermined period of time has elapsed. Then, in the control device 27, the human waste B in the fecal tank 13 is
Since all of the water has been recovered and it is determined that initial water is required, first the switching valve 16 is switched to connect the suction pipe 15 and the communication pipe 19. Then pump 2
0 is operated continuously to suck up the urinal in the urine tank 12 from the suction pipe 15, and the switching valve 16,
Pass through the communication pipe 19 and the discharge pipe 21.

to discharge urine A into the toilet bowl 6. When this suction operation by the pump 20 is performed continuously, all of the urine A in the urine tank 12 is transferred to the urine tank 13, and the urine A is injected into the urine tank 3 as initial water. become.

When all of the urine A in the urine tank 12 is sucked up and the urine tank 12 is empty, the water level for the urine drops, and the water level sensor 23 detects that the urinal is empty, and a signal is transmitted to the detector 25. It will be done.

Therefore, the detector 25 notifies the control device 27 that all the urine has been suctioned, and stops the operation of transferring the urine A. Then, the system? 1[I W W' 27 stops the operation of the pump 20, and then switches the switching valve 16 to connect the suction pipe 17 and the communication pipe 19.

In this state, the urinal tank 13 is filled with initial water, and the water level is located above the filter 18, and the temporary toilet 1 is on standby for the next use. . By repeating this operation sequentially, the urinal used as initial water is always stored in the urine tank 12, and the urine A as the initial water is injected into the urine tank 13 by the pump 20, and the toilet is constantly circulated and purified. This is the same as if water was stored.

Therefore, there is no need to inject the first 1111 water after collecting the human waste B, and the temporary toilet 1 can be used continuously without any other maintenance by simply pumping the stored urine B from the drawing port 22. can do.

FIG. 3 is a flowchart showing the flow of operations of the temporary toilet 1 in FIG. 2.

Next, FIG. 4 does not show another embodiment of the present invention.

A suction pipe 31 is provided inside the urine tank 12 and extends to the bottom thereof. A pump 32 is connected to the upper end of the suction pipe 31. A discharge pipe 33 on the discharge side of the pump 32 is connected to the urine tank 12. It is connected to 13. The water level sensor 23 installed at the bottom of the urine tank 12 is connected to the transfer circuit 34, and at the same time, the water level sensor 23 installed at the bottom of the urine tank 13 is connected to the transfer circuit 34.
is connected to a transfer circuit 34, and the output of the transfer circuit 34 is connected to the pump 32.

A suction pipe 36 is connected to the bottom of the feces tank 13 via a filter 35, and a pump 37 is connected to the upper end of the suction pipe 3G. is connected.

And a start button 28 for starting the cleaning operation.
The output of the control circuit 39 is connected to the control circuit 39.
The output of is connected to a pump 37.

In this embodiment, when a person using the temporary toilet 1 presses the start button 2 after using the toilet bowl 6, the control circuit 39 operates the pump 37 for a certain period of time. Therefore, the moisture in the formal clothes B stored in the stool tank 13 is sucked up from the suction pipe 36 through the filter 35 and is ejected from the discharge pipe 138 onto the inner circumferential surface of the toilet bowl 6. As a result, the filth adhering to the inner wall of the toilet bowl 6 is cleaned, and the human waste B is collected into the feces tank 13.

When a certain amount or more of raw urine B is stored in the stool tank 13, a hose of a vacuum car is inserted through the pumping port 22, and all of the raw urine B in the stool tank 13 is pumped up. This empties the interior of the feces tank 13, but the emptying causes the water level to drop, and this drop in water level is detected by the water level sensor 24. The output of this water level sensor 24 is transmitted to the transfer circuit 34, and the transfer circuit 34 determines that the interior of the feces tank I3 is empty.
After waiting a certain period of time after emptying, the pump 32 is started.

When the pump 32 starts, the urine A in the urine tank 12 is sucked up through the suction pipe 31, and the urine A in the urine tank 12 is sucked up through the suction pipe 31.
The feces are then transferred into the feces tank 13. The operation of this pump 32 is performed continuously, but when all the urinals in the urine tank 12 are sucked up and the inside of the urine tank 12 becomes empty, the water level sensor 23 detects that it is empty. The transfer [11i1 signal is transmitted to the path 34 and the operation of the pump 32 is stopped. As a result, all of the urine A stored in the urine tank 12 is transferred to the urine tank 13,
This urine A will serve as initial water in the feces tank 13.

Further, FIG. 5 shows still another embodiment of the present invention, and the same mechanisms as in FIG. 2 are denoted by the same reference numerals.
The explanation will be omitted.

In this embodiment, a flow hole 4I is opened at the bottom of the partition plate 1 that partitions the inside of the raw urine tank 5.
An on-off valve 42 is connected to this flow hole 4■. A water level sensor 2 installed at the bottom of the fecal tank 13
4 is connected to a valve operating circuit 43, and the output of the valve operating circuit 43 is connected to this on-off valve 42.

In this configuration, the on-off valve 42 is always closed, and urine collected by the urinal 7 is stored in the urine tank 12. Further, the stool and urine collected by the toilet bowl 6 are stored as raw urine B by the toilet bowl 13.

Then, when a predetermined capacity or more of the formal clothes B is stored in the excrement tank 13, a hose of a vacuum car is inserted through the suction port 22, and all the formal clothes B are pumped up.

When all the clothes B have been pumped up, the water level sensor 24
detects that all of the vestments B in the feces tank 13 have been discharged, and notifies the valve operating circuit 43 that the water level in the feces tank 13 has fallen. However, the valve operation circuit 43 does not operate immediately, but after a certain period of time has passed, that is, the valve operation circuit 43
After the hose of the vacuum car is pulled up from 2 and the pumping work is completed, a signal is transmitted to open the on-off valve 42. Therefore, the on-off valve 42 opens, and the urine in the urine tank 12 flows into the feces tank 13 through the flow hole 41 and the on-off valve 42. After a certain period of time has elapsed, the valve operating circuit 43 closes the on-off valve 42 to close communication between the urine tank 12 and the feces tank 13. Then, urine A will flow into the urine tank 12 and the stool tank 13 to the same water level, and this urine A will serve as initial water for cleaning in the urine tank 13. .

〔Effect of the invention〕

Since the present invention is configured as described above, there is no need to inject initial water after drawing up the vesture, unlike conventional circulating toilets, and the urine already stored in the urine tank is used as the initial water. can do. Therefore, there is no need for initial water injection at the time of maintenance, which simplifies maintenance. In addition, since initial water injection is no longer necessary, after installing a temporary toilet,
The temporary toilet can be used for a long period of time, as all that is required is to use a vacuum car or the like to scoop up the collected raw urine.
