Modes for Carrying Out the Invention

[0020] Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings. FIG. 1 is an overall perspective view of a side cross-section from the front side of the mobile toilet 1 of the present invention, and FIG. 2 is a partial cross-sectional perspective view from the back side thereof.

[0021] The movable toilet 1 of the present invention includes a box-shaped container 10 sized to be placed on a moving device 13, toilet units 2a, 2b, 2c, 2d housed in the container 10, a feces and urine tank 3, a middle water pipe 81, a feces and urine discharge pipe 22, a water supply tank 4, and a water supply pipe 41.

[0022] The moving device 13 is configured to be movable as appropriate by wheels 131, 131, for example, by lifting a trailer or the like. The container 10 is configured in a box shape sized to be placed on the loading platform of the trailer. The inside of the container 10 is divided into a toilet housing part 11 and a feces and urine tank housing part 12. In the toilet housing part 11, toilet rooms 11a, 11b, 11c, 11d for housing the toilet units 2a, 2b, 2c, 2d are arranged respectively. Inside the feces and urine tank housing part 12, the feces and urine tank 3 is housed in a state of being placed and fixed on a pallet 31. Between the pallet 31 and the feces and urine tank 3, clips 312 for connecting and fixing both are provided on four surfaces. Insertion holes 311, 311 are formed in the pallet 31 in a direction along the bottom surface. Forks of a forklift or the like can be inserted into the insertion holes 311, 311.

[0023] A water supply tank 4 is further provided inside the feces and urine tank housing part 12. As shown in FIG. 2, a shutter 125 is provided on the front side surface of the feces and urine tank housing part 12, and by opening this shutter 125, the feces and urine tank 3 can be replaced.

[0024] On the side wall of the excrement and urine tank accommodating portion 12, an exhaust port 121 and a guide pipe insertion hole 122 through which the excrement and urine guide pipe 6 communicates are provided. Also, inside the housing 10, an excrement and urine discharge pipe 22 is arranged near the floor surface. The excrement and urine discharged from each toilet 22a, 22b, 22c, 22d and the conveyance water flow into the excrement and urine discharge pipe 22. The excrement and urine discharge pipe 22 is formed in a straight line and is installed in a state inclined downward toward the excrement and urine discharge port 221 at the end. The excrement and urine discharge pipe 22 protrudes to the outside through the discharge pipe insertion hole 123 in the side wall, and the protruding end serves as the excrement and urine discharge port 221. A connection portion 222 is provided at the excrement and urine discharge port 221, and only a specific connection portion having a configuration corresponding to the connection portion 222 can be connected.

[0025] On the other hand, a pump 42 (see FIGS. 4 and 5) is provided in the service water tank 4, and the service water is sent to the service water pipe 41 by this pump 42. The service water pipe 41 is inserted through the excrement and urine tank accommodating portion 12 and the tray chambers 11a, 11b, 11c, 11d, and branch pipes 41a, 41b, 41c, 41d for supplying service water to each tray unit 2a, 2b, 2c, 2d are connected to the service water pipe 41. The service water supplied to each tray unit 2a, 2b, 2c, 2d is used as conveyance water, handwashing water, or cleaning water for the cleaning toilet seat.

[0026] Furthermore, a middle water pipe 81 is provided inside the housing 10. The middle water pipe 81 is arranged in parallel with the service water pipe 41 and, like the service water pipe 41, is inserted through the excrement and urine tank accommodating portion 12 and the toilet chambers 11a, 11b, 11c, 11d. In each toilet unit 2a, 2b, 2c, 2d, one ends of branch pipes 81a, 81b, 81c, 81d are connected to the middle water pipe 81, and the other ends of the branch pipes 81a, 81b, 81c, 81d are detachably and switchably connected to the conveyance water tanks 21a, 21b, 21c, 21d of each toilet unit 2a, 2b, 2c, 2d.

[0027] Next, as shown in FIG. 3, regarding the detachment and switching structure between each of the transfer water tanks 21a, 21b, 21c, 21d, the branch pipes 41a, 41b, 41c, 41d of the upper water pipe, and the branch pipes 81a, 81b, 81c, 81d of the middle water pipe, the transfer water tank 21a will be taken as an example for explanation. Since the configurations of the other transfer water tanks 21b, 21c, 21d are the same, the explanation thereof will be omitted.

[0028] On the back side of the transfer water tank 21a, the lower end of the branch pipe 41a of the upper water pipe and the lower end of the branch pipe 81a of the middle water pipe are located. A socket 42a is connected to the lower end of the upper water branch pipe 41a, and a socket 82a is connected to the lower end of the middle water pipe 81a. Valves are incorporated in the respective sockets 42a, 82a. When a plug 214a provided at the tip of the connection switching pipe 213a is connected, the valve is in an open state, and when the connection is released, the valve is in a closed state.

[0029] A branch 43a is provided on the branch pipe 41a of the upper water pipe on the upstream side of the socket 42a, and one end of a water conduit 44a is connected to the branch 43a. The other end of the water conduit 44a is connected to the cleaning device of the washlet or the faucet for handwashing water.

[0030] The transfer water tank 21a is provided with a water supply port 215a, and the base end of a water supply pipe 211a is connected to the water supply port 215a. The base end of the connection switching pipe 213a is connected to the tip of the water supply pipe 211a via a connection part 212a. A plug 214a is connected to the tip of the connection switching pipe 213a.

[0031] The plug 214a is detachably connected to the socket 42a or the socket 82a. The connection switching pipe 213a is a flexible pipe made of a deformable material. By deforming the connection switching pipe 213a, the plug 214a can be moved between the socket 42a and the socket 82a and connected to either the socket 42a or the socket 82a.

[0032] Inside the transfer water tank 21a, a known transfer water discharge mechanism is provided. For example, a ball tap diaphragm that controls the flow of tap water or reclaimed water supplied from the water supply port 215a, a floating ball that opens and closes the ball tap diaphragm, a discharge port that discharges the transfer water stored in the tank 21a, a rubber float that closes the discharge port, a lever that opens the rubber float, and an overflow pipe 216a that discharges surplus water when the transfer water accumulates above a predetermined amount.

[0033] The floating ball detects the height of the water surface by floating on the water surface of the transfer water accumulated in the tank 21a. When the transfer water accumulates in the tank 21a, the floating ball rises. When the water surface of the transfer water reaches a predetermined height, the floating ball closes the ball tap diaphragm and stops the supply of the transfer water. When the lever is operated to raise the rubber float, the transfer water flows out from the discharge port to the toilet. When the water level drops due to the outflow of the transfer water, the floating ball drops and opens the ball tap diaphragm.

[0034] When the transfer water reaches the height of the tip opening 217a of the overflow pipe 216a, surplus water is discharged from the tip opening 217a, and it is suppressed that the transfer water overflows from the tank 21a. The transfer water in the tank 21a reaches the full water level when the water accumulates and the ball tap diaphragm is closed, and the maximum water level that can accumulate is the height of the tip opening 217a of the overflow pipe 216a. That is, the water level at full water is the water level at which the ball tap diaphragm is closed, or the height of the tip opening 217a of the overflow pipe 216a. The positions of the socket 42a and the socket 82a are located above the height Lt of the tip opening 217a.

[0035] By being positioned in this way, when the plug 214a is replaced between the socket 42a and the socket 82a, it is suppressed that the transfer water leaks from the plug 214a. Also, since the position of the socket 42a is located above the height Lt of the tip opening 217a, when the plug 214a is connected to the socket 42a, it is prevented that the reclaimed water invades the upper water pipe side.

[0036] The other end of the gray water pipe 81 serves as the gray water supply port 82, which protrudes outside the housing 10 as shown in FIG. 2. A connection part 83 is provided at the supply port 82 of the gray water pipe 81, and only a specific connection part having a configuration corresponding to the connection part 83 can be connected.

[0037] The connection part 83 and the connection part 222 have different connection structures, and the connection part that can be connected to the connection part 83 cannot be connected to the connection part 222. By adopting such a configuration, inconveniences such as mistakenly connecting the gray water pipe and the feces and urine discharge pipe are eliminated.

[0038] As shown in FIG. 2, a feces and urine storage tank 5 is connected to the feces and urine discharge port 221. In the feces and urine storage tank 5, feces and urine discharged from each toilet unit 2a, 2b, 2c, 2d through the feces and urine discharge pipe 22 are stored in the tank together with the conveyance water. The suction port 71 of the pump 7 is connected to the discharge port 52 of the feces and urine storage tank 5. The discharge port 72 of the sewage pump 7 with a crushing device is connected to the connection part 62 provided at one end of the feces and urine guide pipe 6. A connection part 61 is also provided at the other end of the feces and urine guide pipe 6. The connection part 61 at the other end of the feces and urine guide pipe 6 reaches into the feces and urine tank accommodating part 12 through the guide pipe insertion hole 122 and is connected to the feces and urine inlet 33 of the feces and urine tank 3. By means of the pump 7, the feces and urine accumulated in the feces and urine storage tank 5 are sent to the feces and urine tank 3.

[0039] The feces and urine guide pipe 6 is made of a deformable pipe material. For example, those made of rubber, resin, or a combination of rubber and resin can be mentioned. In addition, the pipe body constituting the feces and urine guide pipe 6 may be in a bellows shape.

[0040] In this way, by making the feces and urine guide pipe 6 deformable, the handling of the feces and urine guide pipe 6 becomes easy, and as shown in FIG. 4, the connection work to an empty feces and urine tank arranged around the housing 10 can also be easily carried out.

[0041] At the ceiling of the excrement and urine tank 3, a ventilation hole 32 is provided, and a deodorizing filter 34 is attached to the ventilation hole 32. As excrement and urine flow in, the air in the tank is discharged from the ventilation hole 32. At this time, the odor in the tank is also discharged outside the tank. To prevent the foul smell of excrement and urine from leaking, a deodorizing filter made of activated carbon or the like is connected.

[0042] In the movable toilet 1 configured as described above, when the toilet is used, excrement and urine flow into the excrement and urine discharge pipe 22 together with the flushing water. Since the excrement and urine discharge pipe 22 slopes downward toward the excrement and urine discharge port 221, the excrement and urine drainage that has flowed in flows toward the excrement and urine discharge port 221 and flows into the excrement and urine storage tank 5 from the excrement and urine discharge port 221. In this way, the excrement and urine discharged from each toilet are stored in the excrement and urine storage tank 5.

[0043] The excrement and urine stored in the excrement and urine storage tank 5 are pumped up by the pump 7 and flow into the excrement and urine tank 3 in the housing 10 through the excrement and urine guide pipe 6. When the excrement and urine tank 3 is full, the excrement and urine tank 3 is replaced with an empty tank.

[0044] At the time of replacement, open the shutter 125, insert the forks of the forklift into the insertion holes 311, 311 of the pallet 31, remove the full excrement and urine tank 3, and install an empty excrement and urine tank in the excrement and urine tank housing part 12.

[0045] In this embodiment, the excrement and urine tank 3 to be used can be an inexpensive water tank that is generally sold. After the used excrement and urine tank has had its excrement and urine discarded, it is cleaned and reused, and when it becomes severely dirty or malodorous, it is disposed of as industrial waste.

[0046] In addition to replacing the excrement and urine tank 3 that contains the excrement and urine, as shown in FIG. 3, it is also possible to adopt a configuration in which empty excrement and urine tanks 3a, 3b, 3c are arranged around the housing 10. When the excrement and urine tank 3a becomes full, the connection part 61 of the excrement and urine guide pipe 6 can be immediately disconnected and connected to the adjacent excrement and urine tank 3b.

[0047] Note that the reclaimed water supplied to the supply port 82 of the reclaimed water pipe 81 is supplied from an external supply source. Such a supply source may be, for example, a self-treatment device that purifies excrement and urine to generate reclaimed water, a tank storing rainwater, a tank storing river water, or a river.

[0048] As shown in FIG. 5, it may be connected to a self-treatment device that purifies excrement and urine discharged from the discharge port 221 into reclaimed water. The purification device 9 includes a moving device 91 such as a trailer, a purification tank 93 placed on the loading platform of the moving device 91, and a housing 94 that covers the purification tank 93. Wheels 92, 92 are provided on the moving device 91, and it is towed by a tractor or the like and moves.

[0049] The self-treatment device 93 receives excrement and urine and decomposes organic substances, ammonia, etc. in the excrement and urine by biodegradation treatment or the like to purify it to the water quality equivalent to reclaimed water. Inside the housing 94, there are provided a feces and urine pipe 95 that guides excrement and urine to the excrement and urine intake port of the self-treatment device 93, and a reclaimed water pipe 96 that discharges the reclaimed water generated by the purification treatment of the self-treatment device 93. The reclaimed water pipe 96 is connected to the reclaimed water pipe 81 by a reclaimed water connecting pipe 84.

[0050] One end of the excrement and urine guide pipe 6 is connected to the discharge port of the pump 7, and the other end of the excrement and urine guide pipe 6 is connected to the excrement and urine pipe 95 of the purification device 9. Thereby, the excrement and urine discharged at the excrement and urine discharge port 221 are guided to the excrement and urine intake port of the purification tank 93.

[0051] The reclaimed water purified in the purification tank 93 flows from the reclaimed water pipe 96 through the reclaimed water connecting pipe 84 into the reclaimed water pipe 81. The reclaimed water is distributed from the reclaimed water pipe 81 through each branch pipe 81a, 81b, 81c, 81d to each transport water tank 21a, 21b, 21c, 21d. In this way, the movable toilet of the present invention can return the reclaimed water obtained by treating the discharged excrement and urine to each transport water tank through the reclaimed water pipe 81.

[0052] Water may be supplied to each of the water transfer tanks 21a, 21b, 21c, and 21d with tap water instead of reclaimed water. In this case, the reclaimed water pipe 81 is removed, and a water supply pipe 41 with its proximal end connected to the water supply tank 4 is provided. When switching the water supplied to the water transfer tank between reclaimed water and tap water, the reclaimed water pipe 81 and the water supply pipe 41 are also replaced. By not sharing the pipe for supplying water to the water transfer tank, contamination of the water supply pipe by reclaimed water can be prevented.

[0053] In the configuration shown in FIG. 1, the reclaimed water pipe 81 and the water supply pipe 4 are piped. In this case, the tap water supplied from the water supply pipe is used as the washing water for the warm water washing toilet seat. One end of the excrement and urine guide pipe 6 may be directly connected to the excrement and urine discharge port 221, and the other end of the excrement and urine guide pipe 6 may be extended and used up to a place where it can be drained, such as a sewer.

[0054] The movable toilet configured as described above may not have the moving device 13 and may be directly installed on the ground surface. In this case, for example, the housing 10 can be lifted by a crane or the like to be moved.
