Description

  The present invention relates to a flush-type temporary toilet that can be adapted to the electrical environment of an installation location.

  Currently, mobile temporary toilets are often used in construction sites and event venues where toilets are needed temporarily but are not needed in the future. Also, in outdoor facilities such as parks, riverbeds, mountain trails, beach parks, campsites and the like, there are many similar mobile temporary toilets even in places where it is difficult to install permanent toilets as buildings.

  Conventionally, as such a temporary toilet, a sink type that drops filth directly into a filth tank has been used, but recently, a flush type has been used for hygienic reasons. However, because the amount of water used is often limited in the installation environment of temporary toilets, a method that uses a large amount of water, such as a drop type that drops a wash water from a water tank above the toilet, is used. It is difficult to pump and often pumps a limited amount of water. For example, as described in Patent Document 1, a toilet using a foot pump is used.

  In this toilet, a foot pump that is driven by human power requires a certain amount of force, so that a weak child may not be able to flow water sufficiently. For this reason, naturally, it is preferable from the viewpoint of convenience that the pump is moved using electricity. On the other hand, the environment where a temporary toilet is installed is often an environment where electricity is not connected. For this reason, as in Patent Document 2, electricity is secured in a temporary toilet using a solar cell.

Japanese Patent Laid-Open No. 10-25789 JP 2006-223655 A

  However, there are few conventional temporary toilets on the premise that they are used in places where electricity is prepared. Moreover, there is a problem that a temporary toilet using electricity can only be used in an environment where electricity is available.

  For this reason, even if you try to move the temporary toilet that is no longer needed at the previous installation location to another location, if it is based on the use of electricity, bring it to a place where electricity is not connected. I couldn't go, and I couldn't use electricity even if I took it to a place where electricity was available if it was not premised on the use of electricity. Therefore, if electricity can be used in the presence of electricity, a temporary toilet suitable for each electric equipment must be prepared separately.

  Furthermore, even if the surrounding environment was prepared and electricity could be used while installing a temporary toilet at a construction site or the like, the electricity could not be used in a temporary toilet that does not assume the use of electricity.

  On the other hand, if a solar cell is used for a temporary toilet as described in Patent Document 2, electricity can be used regardless of the surrounding power transmission environment. However, since solar cells are expensive, it is better to prepare two types of temporary toilets according to the presence or absence of electricity, rather than the installation cost of temporary toilets. Moreover, it is not easy to secure an electric capacity sufficient to drive the pump with a solar cell, and there is also a problem that it cannot be used when it is cloudy and rainy.

  Therefore, the present invention has an object to make it possible to use a flush-type temporary toilet universally regardless of the presence or absence of electricity at the place of installation, and to use electricity without changing equipment after power transmission. To do.

The present invention relates to a human-powered pump for manually supplying a movable temporary toilet having a washing pipe for supplying washing water for washing a toilet bowl and a water storage tank for storing the washing water from the water storage tank to the washing pipe. And an electric pump that sends cleaning water from the water storage tank to the cleaning pipe by electric drive, so that it can be used with or without electricity.
That is, the electric pump is used in an environment where power is transmitted, and the human power pump is used in an environment where power is not transmitted, so that water can be washed in either case.

  One washing pipe for supplying washing water from the human-powered pump and the electric pump to the toilet bowl may be provided for each pump, but the water feeding pipes from each pump are joined together, and the joining pipe is connected to the toilet bowl. If it is connected to one washing tube provided in the toilet, the structure of the toilet can be simplified. In this case, by installing a check valve in the water supply pipe from the electric pump to prevent the backflow to the electric pump, the water flow is not This prevents the water pressure from further flowing into the water and further reducing the water pressure.

  The location where the above-described check valve is provided is not particularly limited as long as it can prevent backflow to the electric pump. At this time, by using a non-electric check valve as the check valve, it is possible to prevent the check valve from acting even if there is no power source to prevent the back flow and to reduce the water pressure for washing the toilet.

  In addition, since the water pressure by the electric pump is higher than the water pressure by the human-powered pump, the water pressure for washing the toilet can be ensured to a necessary level even if it flows backward to the human-powered pump to some extent. Therefore, if a non-electric check valve is also provided in the water supply pipe from the human-powered pump, it is possible to suppress the water pressure from flowing back to the human-powered pump when the electric pump is used.

  When the water pipes from each of the above pumps are merged with a three-way joint, and the joint is a check valve structure, the water pipe can be merged and the check valve can be used to prevent back flow with a single component. The structure is simplified and manufacturing is easy. In this case, if a check valve is provided at the port connected to the water supply pipe from the electric pump among the three-way joints, there is no side effect other than preventing back flow to the electric pump, and the water pressure is controlled efficiently. Can do. The structure of the three-way joint may be Y-shaped or T-shaped.

  As a specific structure of the non-electric check valve provided in the above three-way joint, a valve seat is formed in a cylindrical mouth portion connected to a water supply pipe from an electric pump, and a valve body that contacts and separates from the valve seat is provided. One loaded. This is a structure in which the three-way joint can be T-shaped or Y-shaped, but it works as an effective check valve particularly in the case of a T-shaped three-way joint. When the water flow comes only from the human-powered pump, the valve body is accommodated in the valve seat, and the water flow to the electric pump can be blocked. More specifically, by making the valve body spherical, it can be easily fitted into the valve seat. Also, by providing a projection in the three-way joint that prevents the spherical valve body from moving to the other mouth, the valve body moves to the other mouth and does not fit properly in the valve seat. Can be prevented. For example, if the valve body moves to the mouth portion on the merging pipe side, it will not fit in the valve seat by the water flow from the human power pump, but will block the merging pipe that leads to the washing pipe, Such a situation can be prevented by the protrusion.

  When a check valve is also provided on the water supply pipe from the human power pump, a valve seat is also formed on the cylindrical mouth portion to which the water supply pipe from the human power pump is connected. When the valve body is provided, the backflow to the human power pump can be suppressed by the same operation as described above.

  The structure of the above-mentioned human power pump is not particularly limited, and it may be operated by hand or operated by foot. Among these, it is preferable to use a foot pump that is operated by depressing a pedal, because the washing water can be discharged with a strong force by applying a human weight efficiently. On the other hand, in order to operate the electric pump, it is only necessary to input an electric switch. Therefore, the form of the operation switch of the electric pump is not particularly limited. However, it is preferable that the electric pump is switched on and the power is supplied by depressing the pedal of the human-powered pump because the operation system can be integrated into one and the configuration in the temporary toilet can be simplified.

  In this case, if the switch is turned on immediately after the pedal is depressed, the electric pump may be turned on just by accidentally touching the pedal. If the electric pump is switched on when it is depressed by about a half, the possibility of malfunction can be suppressed. In addition, it is possible to attach a stopper that prevents the pedal from being depressed more than the point where the electric pump is switched on, and if this stopper is provided when supplying power, the human-powered pump will not operate any more, so extra washing water will be required. Can be avoided.

  For water supply to the water storage tank, an open / close valve that can be connected to the water supply system is provided, and this open / close valve is opened and closed by a ball tap provided in the water storage tank, regardless of whether there is a power supply or not. The supply to the tank can be controlled. In addition, if a water supply port that can supply water directly to the water storage tank with a bucket or the like is provided, the temporary toilet can be used even in a place where the water supply cannot be used.

  Moreover, temporary accumulation of sewage becomes possible by providing a sewage tank that temporarily stores sewage after use of the toilet bowl below the toilet. In addition, if drains with lids are provided at the bottom and back of the sewage tank, even if there is no power supply, the drains can be connected to external sewage tanks at the bottom or rear of the temporary toilet, or to the nearby sewer. Draining is possible by dropping. On the other hand, if an electric sewage pump is provided in the sewage tank, forcible drainage can be performed when power is supplied, and sewage can be sent to an external sewage tank or sewer at a remote location. By providing both of these drains and the sewage pump, when there is no power source, drainage is performed using the drain, and when there is a power source, drainage can be performed using a sewage pump to a location away from the temporary toilet. Thereby, the quantity of the residue which remains in a sewage tank can be suppressed.

  The temporary toilet according to the present invention can be used regardless of whether electricity passes through the installation place, and can use the electricity if electricity passes. Since the operator can install regardless of the power transmission status, the user can receive the maximum benefit from the power source without preparing a separate toilet for each power transmission status. In addition, when power is transmitted during installation at a location where power is not transmitted, it is possible to use electricity more comfortably without changing the unit.

Embodiments of a temporary toilet according to the present invention will be described below with reference to the accompanying drawings.
FIG. 1 shows an outline of a temporary toilet according to the embodiment. There is a door 1 on the front, and the other three sides are covered with a wall 2 to form one unit. When the door 1 is opened, there is a floor portion 3 that is higher than the installation location of the temporary toilet, and a unit body 4 is attached to the back thereof.

  FIG. 2 shows a main configuration of the unit body 4. A multi-tank lid 12, which is also a tread board, rides on the multi-tank 11 that also serves as a base, and a plastic toilet 13 is fitted into a hole that is vacant in the central portion on the near side of the lid. These unite together to form the unit body 4. At the time of installation, the floor 3 to the multi-tank lid 12 are stepped, the remaining amount window 16 can be confirmed from the front, and a pedal 32 described later protrudes above the floor 3.

  FIG. 3 is a plan view of the inside of the multi-tank 11 as viewed from above. A sewage tank 21 is housed in the center in the left-right direction of the multi-tank 11, and this is a sewage tank chamber that receives sewage discharged from the toilet 13. The left and right compartments separated by the sewage tank 21 serve as water storage tanks 22 and 22 'for storing water before use. Under the sewage tank 21, a gap 24 is provided between the bottom surface of the multi-tank 11 and the gap 24 is connected to the left and right water storage tanks 22 and 22 'so as to be integrated. A human-powered pump box 23 for storing a human-powered pump 31 (to be described later) is housed on the front side of the right water storage tank 22 '.

  The multi-tank 11, the sewage tank 21, and the human-powered pump box 23 are all made of plastic and prevent water from entering and leaking.

  FIG. 4 shows a front view of the multi-tank 11. A vertical slit 15 for passing a pedal 32, which is a movable part for operating the human-powered pump 31, to the front side is vacant on the right front surface of the multi-tank 11 that houses the human-powered pump box 23. Although not shown, the human-powered pump box 23 is also provided with a vertical slit for passing the pedal 32 at a position where it is combined with the vertical slit 15 vacated in the multi-tank 11. Further, the human-powered pump box 23 and the multi-tank 11 are bonded so that water does not pass through these vertical slits so that water does not pass from the water storage tanks 22 and 22 ′. Further, a remaining amount window 16 for confirming the water level of the water storage tank 22 from the outside is attached to the left front surface of the multi-tank 11.

  FIG. 5 shows a rear view of the multi-tank 11. In the central part where the sewage tank 21 is accommodated, a sewage drainage drain 17 for discharging sewage by gravity is provided at the lower part and is directly connected to the sewage tank 21. Separately, a pump discharge port 18 serving as an outlet for sewage discharged from a sewage pump 51 described later is provided. Furthermore, a water supply direct connection bolt 19 that can be connected to a water supply pipe for water supply is provided on the back surface of the water storage tank 22 of the multi-tank 11 on the right side in FIG.

  FIG. 6 shows a plan view from above of the unit main body 4 in a state where the multi-tank lid 12 and the toilet bowl 13 are placed on the multi-tank 11, that is, in a used state. The multi-tank lid 12 is provided with a water supply port 25 connected to the water storage tank 22, and is covered with a water supply port cover 26. When water is supplied from a bucket or a water supply vehicle, the water supply cover 26 is removed and water is supplied from the water supply opening 25 to the water storage tank 22.

  A flush water discharge nozzle 27 for discharging a water flow for washing is provided in the interior of the toilet 13, and the wash water a is discharged from here into the toilet 13 regardless of whether power is supplied. Further, a downward drop hole 28 is vacant in the central portion of the toilet 13. The discharge direction of the washing water spouting nozzle 27 does not face the drop hole 28 but faces the inclined portion around the drop hole 28 that falls toward the drop hole 28. For this reason, the discharged water does not immediately fall into the drop hole 28, but falls after being swung around the drop hole 28 and washed.

  FIG. 7 shows a side view of only the toilet 13. The above-described drop hole 28 is usually closed with a flapper 29 from below. The flapper 29 is temporarily opened downward by the weight on the upper surface, and can drop manure and sewage into the sewage tank 21. After the fall, the flapper 29 is automatically closed by a spring, and the odor rises from the sewage tank 21. To prevent it from coming.

  FIG. 8 shows equipment and wiring piping diagrams provided in the sewage tank 21, the water storage tanks 22 and 22 ′, and the human-powered pump box 23 in the multi-tank 11.

  FIG. 9 shows a cross-sectional view of the inside 23 of the human-powered pump box. A human power pump 31 is provided in the human power pump box 23. The human-powered pump 31 operates by depressing a pedal 32 that protrudes toward the front side of the multi-tank 11 through the vertical slit 15. When activated, the water in the water storage tank 22 ′ is taken from the water pump pipe 23 extending from the human-powered pump box 23, that is, the water storage tank 22 ′, and water is supplied to the first water supply pipe 34 extending to the back side of the multi-tank 11. Send it out. The first water pipe 34 is connected to a three-way joint 35 described later.

  An electric pump 37 is provided in the left water storage tank 22. The electric pump 37 sends the water in the water storage tank 22 to the three-way joint 35 described later through the second water supply pipe 36 by electric drive. The switch 38 for operating the electric pump 37 is attached to a movable part of the human-powered pump 31 in the human-powered pump box 23 and is connected to the electric pump 37 by a signal cable 39 for transmitting input. When electricity is supplied from the power cable 41, when the pedal 32 is depressed, the switch 38 is turned on halfway, and the electric pump 37 is activated to supply water in the water storage tank 22 through the second water supply pipe 36. A predetermined amount is sent to the three-way joint 35. At this time, the human-powered pump 31 also operates. However, since the electric pump 37 sufficiently supplies water in the middle of the depression, it is not necessary to depress it until the end. When the position where the switch 38 is in the middle is about 10 to 20% of the movable range from the start of the movement of the pedal 32, it is possible to suppress the malfunction of the electric pump 37 when the pedal 32 is accidentally touched. .

  When power is supplied, a stopper 49 (shown by a broken line in FIG. 9) is attached to a place where the pedal 32 is depressed and the switch 38 is turned on, and is not further depressed. This prevents the user from stepping on the pedal 32 to the end, prevents extra water from being pumped out from the human-powered pump 31, and saves water.

  FIG. 10 shows a cross-sectional view of the three-way joint 35. The flow path fed from the human-powered pump 31 through the first water supply pipe 34 and the flow path fed from the electric pump 37 through the second water supply pipe 36 are combined at the three-way joint 35, and the flow path of the single junction pipe 40. Then, the water is sent to the cleaning pipe 42 that leads to the cleaning water discharge nozzle 27. A protrusion 43 is provided at the place where the two flow paths meet, and a valve body 44, which is a water stop ball, is inserted between the protrusion 43 and the second water supply pipe 36. The range of movement of the valve body 44 is limited by the protrusion 43, and the valve body 44 does not move to the cylindrical mouth portion 46 on the first water supply pipe 34 side or the cylindrical mouth portion 48 on the merging pipe 40 side.

  A valve seat 45 in which the valve body 44 is accommodated is provided in a cylindrical mouth portion 47 connected to the second water pipe 36 of the three-way joint 35. When the operation is performed only by human power without turning on the power, water is supplied only from the first water supply pipe 34 side, the valve body 44 is accommodated in the valve seat 45, and the water flow is blocked. Thereby, the liquid flow by the human-powered pump 31 is prevented from flowing back to the electric pump 37, and the electric pump 37 is prevented from being damaged. The water flow that cannot reach the second water supply pipe 36 is directed only to the merging pipe 40, and is discharged into the toilet 13 from the washing water discharge nozzle 27 through the washing pipe 42. For this reason, the toilet 13 can be washed without killing the momentum of the water flow from the human-powered pump 31 that is difficult to feed with sufficient water pressure.

  On the contrary, when the power is turned on and the electric pump 37 is operated, the valve body 44 is separated from the valve seat 45 and caught by the protrusion 43 due to the water flow from the second water supply pipe 36 side. At this time, the water flow goes around the protrusion 43 and the valve body 44 and flows to the joining pipe 40, and is discharged from the washing water discharge nozzle 27 through the washing pipe 42 leading to the toilet 13. Although the water flow also flows to the first water supply pipe 34 side, the water pressure by the electric pump 37 can be made stronger than the water pressure by the human power pump 31, so even if a part of the water flow flows into the human power pump 31 side, the toilet 13 The cleaning water a can be discharged at a water pressure at which the cleaning can be performed to some extent. Moreover, the human-powered pump 31 has a simpler structure than the electric pump 37, and is less likely to be damaged even if it flows backward.

  However, a valve seat 45 ′ is also provided in the cylindrical mouth portion 46 connected to the first water supply pipe 34 from the human-powered pump 31 of the three-way joint 35, and a valve body 44 ′ (between the projection 43 and the valve seat 45 ′ ( 10 is shown on the right side in FIG. 10), it is possible to reliably prevent backflow to the human-powered pump 31, and the toilet 13 can be washed without killing the momentum of the water flow from the electric pump 37. .

  The difference in operation between when the power is turned on and when it is not turned on is that there is no need to perform any particular switching, and the operation according to the state of the water flow into which the three-way joint 35 serving as a non-electric check valve flows. It has been realized.

  FIG. 11 shows a sectional view from the side of the toilet 13 and the sewage tank 21. The sewage discharged from the washing water discharge nozzle and washing the toilet 13 opens the flapper 29 from the drop hole 28 and falls into the sewage tank 21.

  FIGS. 12A and 12B show a method for discharging sewage from the sewage tank 21 when power is not supplied. Among these, FIG. 12A shows a case where the sewage b in the sewage tank 21 is drained by opening the drain 17 for sewage drainage behind the back of the sewage tank 21 and dropping it downward with the attached hose 50. Show. The hose 50 may be connected to a sewer 61 at the rear rear as shown in FIG. 12A, or may be connected to an external sewage tank 62 provided separately at the rear rear. The external sewage tank 62 may be one that microbially decomposes filth inside, or one that periodically removes dirt. However, since it is used in a state where the power is not turned on, the sewer 61 and the external sewage tank 62 need to be installed in a range close to the temporary toilet so that the sewage automatically moves when dropped through the hose 50.

  FIG. 12 (b) shows a case where sewage is dropped into an external sewage tank 62 provided directly below the temporary toilet through a direct drain 53 at the center of the sewage tank 21. The direct drain 53 also penetrates the central portion of the multi-tank 11. In this case, the sewage drainage drain 17 is covered. The direct drain 53 is also covered when not in use. Since the direct drain 53 is directly connected to the external sewage tank 62, the odor is more likely to be trapped than when it is sent to the outside through the hose 50. However, since the sewage can be dropped from the sewage tank 21 as it is, It is hard to collect. Moreover, it can be handled as an integral part of the temporary toilet itself.

  FIGS. 13A and 13B show a method for discharging sewage from the sewage tank 21 when power is supplied. At the timing when washing by the electric pump 37 is finished and sewage flows into the sewage tank 21, the electrically driven sewage pump 51 provided in the sewage tank 21 is operated. The sewage pump 51 forcibly discharges the sewage b in the sewage tank 21 from the pump discharge port 18 to the outside of the toilet through the discharge pipe 52. In this case, since the drainage can be sent out by applying pressure, it can be sent out even if the sewer 61 shown in FIG. 13A and the external sewage tank 62 shown in FIG. When the drainage is finished, the sewage pump 51 is stopped, and then the electric pump 37 is operated again so that the cleaning water flows and some water is accumulated in the sewage tank 21. Thereby, it is prevented that dirt is stuck in the dirty water tank 21.

  The time when the sewage tank 21 is activated and stopped, and the timing of the subsequent re-operation of the electric pump 37 are automatically controlled by the controller 54 provided in the human-powered pump box 23 through the signal cable 39 and the composite cable 57. . The controller 54 is a programmed control circuit that can issue an operation stop signal at an appropriate timing. The composite cable 57 is connected to the signal cable 39 and also to the power cable 41, and supplies a signal and power to the sewage pump 51.

  On the other hand, the amount of water in the water storage tanks 22 and 22 'is reduced by washing. If there is no water supply facility, water is supplied to the water storage tank 22 through the water supply port 25 by manual operation with a water supply vehicle or a bucket before the washing water is used up. The water storage tank 22 and the water storage tank 22 ′ are connected through a gap 24 provided at the bottom of the sewage tank 21, and the water levels are the same.

  When there is a water supply facility, the water supply is connected to a water supply direct connection bolt 19 so that water can be supplied to the water storage tank 22 from there. The water supply direct connection bolt 19 is provided with an opening / closing valve 56 for stopping water supply when the ball tap 55 floating on the water surface in the water storage tank 22 reaches a certain height. The on-off valve 56 operates without using electricity depending on the water level of the ball tap 55, so that it can be operated regardless of the presence or absence of electricity, and the water level in the water storage tanks 22 and 22 'can be maintained.
