<Overall composition>
Hereinafter, an emergency flush toilet system 1 according to an embodiment of the present invention (hereinafter referred to as "this embodiment") will be described with reference to FIG.

FIG. 1 is a schematic diagram showing an example of an emergency flush toilet system 1 according to this embodiment.

As shown in FIG. 1, the emergency flush toilet system 1 includes a flush toilet 10, a solid-liquid separation unit 20, a first tank 50, a first pump 52, a purification unit 54, and a second tank 56. , an ozone generator 58 and a second pump 60 .

The flush toilet 10 has, for example, a toilet bowl, a toilet seat, a lid, a cleaning sensor, and the like. This cleaning sensor detects a cleaning instruction from the user of the flush toilet 10 . For example, when the cleaning sensor detects a cleaning instruction from the user, the cleaning sensor operates the second pump 60 to supply cleaning water to clean the toilet bowl, and to clean the objects to be treated (for example, urine, feces, toilet bowl, etc.) in the toilet bowl. paper, etc.) into the sewage or solid-liquid separation unit 20 . As for this flushing sensor, for example, various sensors that detect that the flushing lever is lowered by the user, various sensors that detect that the user stands up from the toilet seat, and sensors that detect that the user's hand is approaching. non-contact sensors, etc.
Here, in normal times, the material to be treated is discharged into the sewage by the electromagnetic valve B1. On the other hand, in an emergency in which the functions of the water supply and sewage systems are stopped due to the occurrence of a disaster or the like, the material to be treated is discharged to the solid-liquid separation unit 20 by the electromagnetic valve B1. That is, in an emergency, the liquid separated and purified by the solid-liquid separation unit 20, purification unit 54, etc. is reused as washing water.

The solid-liquid separation unit 20 separates solids and liquids contained in the waste discharged from the flush toilet 10 . Examples of the solids include stools, toilet paper and other filth. In addition, examples of the liquid include sewage such as urine and washing water.

The first tank 50 stores the liquid separated by the solid-liquid separation unit 20 . In addition, the first tank 50 has a sensor that measures the volume of the stored liquid. Examples of such sensors include weight sensors and optical sensors.

The first pump 52 sends the liquid stored in the first tank 50 to the purification unit 54 . For example, the first pump 52 operates when the volume of liquid in the first tank 50 is full and sends the liquid to the purification unit 54 . Also, for example, the first pump 52 stops operating when the liquid volume in the first tank 50 is empty (zero). The first pump 52 stops operating when the second tank 56 is full of liquid regardless of the amount of liquid in the first tank 50 .

The purification unit 54 purifies the liquid (sewage) sent from the first tank 50 . For example, the purification unit 54 is covered with layers of zeolite, activated carbon, or the like, and deodorizes and decolorizes the passing liquid. In addition, in the purification unit 54, deodorization or the like may be performed using chemicals or microorganisms (for example, biofilms or plant rhizosphere microorganisms).

The second tank 56 stores cleaning water. In this embodiment, the second tank 56 stores the liquid or tap water purified by passing through the purification unit 54 . For example, in normal times, tap water is sent to the second tank 56 by the electromagnetic valve B2.

The second tank 56 also has an ozone generator 58 . This ozone generator 58 is a device for deodorizing and sterilizing the liquid fed from the first tank 50 . The ozone generator 58 is provided with a timer for automatically stopping the operation, and the operating time is limited for the purpose of power saving and to prevent health damage to the human body due to an increase in ozone concentration. Note that this operating time may be controlled (managed) by the control unit 46, which will be described later.

The second tank 56 also has a sensor that measures the volume of the liquid (cleaning water) stored. Also, the solenoid valve B2 has a sensor (for example, an optical sensor) that detects that tap water is being fed (supplied).

The second pump 60 feeds the liquid (flush water) stored in the second tank 56 to the flush toilet 10 . For example, the second pump 60 operates when the flush sensor of the flush toilet 10 detects a flush instruction.

(Specific example 1)
2 to 5 are schematic diagrams showing an example (specific example 1) of the solid-liquid separation unit 20 according to this embodiment.

As shown in FIGS. 2 to 5, the solid-liquid separation unit 20 includes a first drain port 22, a filter 24, a lattice network 26, a first guide roller 28, a second guide roller 30, a height sensor 32 , a delivery roller 34 , a winding roller 36 , a motor 38 , a second drain port 40 , a power supply 42 , a blower 44 , and a controller 46 .

The first drain port 22 is a drain port through which the material discharged from the flush toilet 10 passes. The area of the first drain port 22 increases, for example, downward (in the direction of gravity), and is configured so that the filtering area of the filter 24 expanded in the horizontal direction increases. In addition, the first drain port 22 has an elevating means (not shown). This elevating means is realized by, for example, an elevating motor. This elevating means is controlled by, for example, the control section 46 . This elevating means, for example, raises the first drain port 22 at the timing when the motor 38 starts operating, and at the timing when the motor 38 stops operating, the lower part of the first drain port 22 expands in the horizontal direction. Lower to ground on filter 24 . Thereby, the filter 24 can be smoothly wound up by the winding roller 36 .

The filter 24 is a filtering material that is spread horizontally between the delivery roller 34 and the take-up roller 36 and separates solids and liquids contained in the waste discharged from the flush toilet. Objects to be treated fall from the first drain port 22 to the horizontally spread filter 24 , solid matter remains on the upper surface (upper surface) of the filter 24 , and liquid passes through the filter 24 downward ( direction of gravity). Examples of the filter 24 include gauze made of plant material, non-woven fabric made of resin, and the like. In addition, the filter 24 may be configured in a plurality of layers, or may be provided with irregularities (pleats or the like) so that solid matter can easily adhere (adsorb).

In the present embodiment, the filter 24 has a portion (unused portion) where solid-liquid separation has not been performed (unused portion) wound around the delivery roller 34 in a roll shape, and a portion (used portion) where solid-liquid separation has been performed is It is configured to be wound into a roll on a winding roller 36 . A constant tension is applied to the filter 24 to suppress the occurrence of wrinkles and sagging.

Further, in the present embodiment, the used filter 24 (the filter 24 with solid matter attached) wound up by the winding roller 36 is replaced with a new filter 24 by, for example, the administrator of the emergency flush toilet system 1. It is possible. For example, when the filter 24 is completely wound around the winding roller 36, the administrator of the emergency flush toilet system 1 collects part or all of the solid-liquid separation unit 20 including the filter 24 as a cassette ( removal), and a cassette containing a new filter 24 (part or all of the solid-liquid separation unit 20) can be installed in the emergency flush toilet system 1. That is, part or all of the solid-liquid separation unit 20 is detachable as a cassette. This cassette includes at least filter 24 .

The grate 26 supports the horizontally spread filter 24 between the delivery roller 34 and the take-up roller 36 . The lattice network 26 has holes that allow the liquid that has passed through the filter 24 to pass downward (in the direction of gravity). Examples of the lattice mesh 26 include a metal net and metal punching.

The first guide roller 28 is provided at the end of the grid net 26 on the feed roller 34 side, and guides the filter 24 fed from the feed roller 34 to the upper surface of the grid net 26 . For example, the first guide roller 28 is composed of two rollers, and guides the filter 24 by sandwiching the filter 24 between the two rollers.

The second guide roller 30 is provided at the end of the grid net 26 on the winding roller 36 side, guides the filter 24 wound by the winding roller 36, and guides the solid contained in the material to be processed to the filter 24. It adheres (adsorbs) matter and squeezes the water contained in solid matter. For example, the second guide roller 30 is composed of two rollers, and guides the filter 24 and adheres and presses the solid matter by sandwiching the filter 24 between the two rollers.

A height sensor 32 detects the height of solids remaining on the horizontally spread filter 24 . This height sensor 32 detects, for example, that the height of the remaining solid material has reached a predetermined value (eg, 7 centimeters).

The delivery roller 34 is wound with the filter 24 that has not undergone solid-liquid separation. The filter 24 wound around the delivery roller 34 is reduced as the take-up roller 36 rotates.

The winding roller 36 winds up the filter 24 and the solid matter separated by the filter 24 into a roll. The filter 24 wound on the winding roller 36 increases as the winding roller 36 rotates. The winding roller 36 has a motor 38 for winding the filter 24. By rotating the motor 38, the solid-liquid-separated filter 24 and the solid matter adhering to the filter 24 are removed. wind up.

The second drain port 40 is a drain port for reusably draining the liquid separated by the filter 24 as washing water. For example, the second drain port 40 drains the liquid into the first tank 50 .

The power supply 42 supplies power to the entire emergency flush toilet system 1 . For example, the power supply 42 supplies power to operate various sensors, various pumps, the motor 38, the blower 44, the control unit 46, and the like. This electric power is supplied from, for example, a storage battery, a solar panel, a small generator, or the like.

The blower 44 blows air to the filter 24 and the solid matter to dry the filter 24 and the solid matter. The filter 24 includes the filter 24 horizontally spread between the delivery roller 34 and the winding roller 36 and the filter 24 wound up by the winding roller 36 .

The control unit 46 controls the entire emergency flush toilet system 1 . For example, the control unit 46 includes a CPU, memory, receiving means, operating means, and the like. As this receiving means, for example, an antenna for receiving radio waves can be used. Moreover, as the operation means, for example, a changeover switch, a button, or the like for receiving an instruction operation from the administrator of the emergency flush toilet system 1 can be used.

In this embodiment, the control unit 46 controls the solenoid valve B1, the solenoid valve B2, the motor 38, the blower 44, and the like.

Further, in the present embodiment, the control unit 46 switches the solenoid valves B1 and B2 when there is an instruction to switch from the normal state to the emergency state. This switching instruction includes reception of a signal (e.g., radio wave) notifying of an emergency by the national or local government, switching operation to an emergency by the administrator of the emergency flush toilet system 1, and supply of clean water at the solenoid valve B2. (Supply) detection and the like. Specifically, when there is an instruction to switch from the normal state to the emergency state, the control unit 46 controls to switch the electromagnetic valve B1 to discharge the object to be processed to the solid-liquid separation unit 20, and the electromagnetic valve B2 is switched to stop the supply of clean water.

Further, in the present embodiment, the control unit 46 switches the solenoid valves B1 and B2 when there is an instruction to switch from emergency to normal. This switching instruction includes reception of a signal (e.g., radio wave) that notifies the normal state by the national government or local government, switching to the normal state by the administrator of the emergency flush toilet system 1, and supply of clean water by the electromagnetic valve B2. detection of being (supplied). Specifically, when there is an instruction to switch from the emergency state to the normal state, the control unit 46 switches the electromagnetic valve B1 to discharge the material to be treated into sewage, and switches the electromagnetic valve B2. It is controlled so that clean water is fed (supplied).

Further, in this embodiment, the control unit 46 automatically operates the motor 38 when a predetermined condition is satisfied. The predetermined condition is that the number of times the flushing instruction is detected by the flushing sensor that detects the flushing instruction from the user of the flush toilet reaches a predetermined number (for example, 5 times), or that the horizontally spread filter For example, the height detected by the height sensor 32 for detecting the height of the solid matter remaining in the chamber reaches a predetermined value. Here, the controller 46 controls the rotation speed of the motor 38 so as to wind the filter 24 from the first guide roller 28 to the second guide roller 30 (for example, 30 cm). Since the diameter of the filter 24 wound on the winding roller 36 increases as the filter 24 is gradually wound on the winding roller 36, the control unit 46 controls the motor 38 to operate. Alternatively, the rotation speed of the motor 38 may be reduced. Specifically, the control unit 46 sets the number of rotations of the motor 38 to 10 at first, and decreases the number of rotations by one each time the motor 38 winds the film a predetermined number of times (for example, four times).

Further, in the present embodiment, after the used filter 24 is wound onto the winding roller 36 by the motor 38, the control unit 46 operates the blower 44 for a predetermined period of time (for example, 3 minutes).
