However, the temporary toilet described in Patent Document 1 is such that water supply and discharge are performed simultaneously while the cleaning switch is turned on, and the operation of the cleaning switch must be continued for a certain period of time. there were. Further, if the cleaning switch is on for a short time, the toilet bowl may not be sufficiently cleaned.
Furthermore, if the cleaning switch is turned on for a short time, if the distance between the temporary toilet and the sewage system is far away, or if there is a difference in height between the temporary toilet and the sewage system, the waste will be discharged into the sewage system. There is concern that it will be difficult to pump. In addition, when the user exits the temporary toilet without being turned on after being excreted in the toilet bowl, there is a problem that ammonia odor is filled in the temporary toilet. Such a problem is particularly emphasized when a temporary toilet is installed in a narrow land site, a residential area, or in a town.
This invention is made | formed in view of the said problem, The objective is to provide the temporary toilet which can be maintained cleanly by automatic control.
Another object of the present invention is to provide a temporary toilet with high drainage capacity.

According to the first aspect of the present invention, when the human body sensor is turned off without the cleaning switch being turned on, and when the cleaning switch is turned on, the control device performs a cleaning process. Thereby, it becomes possible to maintain a temporary toilet cleanly by automatic control.
Control device, a cleaning process is performed in the following steps. First, in the primary water supply, the electromagnetic valve is opened, the toilet is washed, and the amount of water necessary for the operation of the drainage pump is stored in the waste receiving tank. Next, in the drainage operation, when a predetermined amount of water is stored in the filth receiving tank after the start of primary water supply, the drainage pump is operated to discharge water and excrement in the filth receiving tank.
In the primary water supply, the excrement and paper are agitated in the waste receiving tank by the water supply. Then, the amount of water necessary for the operation of the drainage pump is stored in the waste receiving tank in the next drainage operation.
In the draining operation, water, excrement, and paper stored in the waste receiving tank are discharged at a time. At this time, since water is sufficiently stored in the waste receiving tank, air is suppressed from being mixed into the dirty water drained by the impeller of the drain pump. For this reason, since the impeller reliably grasps the water, the drainage pump can enhance the drainage capacity. Therefore, it is possible to install a temporary toilet even in a place that is far from the sewage facility and has a height difference.
Et al is, in the secondary water, after the primary water supply ends, the drainage pump to discharge the excrement in the dirt receiving tank, it opens the solenoid valve, for storing water into the waste receiving vessel. Thereby, when the temporary toilet is used next, the excrement absorbs moisture so that the discharging operation can be easily performed. In addition, the water stored in the waste receiving tank prevents the odor from being filled from the drainage system into the box.

According to the invention which concerns on Claim 2 , a control apparatus performs a washing process automatically automatically. For this reason, maintainability can be improved. In addition, the drainage hose can be prevented from freezing and drying. The period of this cleaning process can be arbitrarily set according to the use conditions of the installation place.

According to the invention of claim 3 , the drainage operation is started before the end of the primary water supply. Thereby, leakage of water from the filth receiving tank can be prevented, the volume of the filth receiving tank can be reduced, and the temporary toilet can be reduced in weight.

According to the invention which concerns on Claim 4 , secondary water supply is started before completion | finish of drainage operation | movement. For this reason, it is possible to prevent the impeller of the drainage pump from idling due to air mixed into the sewage before the drainage operation is completed.

According to the fifth aspect of the present invention, when the human body sensor is turned on, the control device energizes the illumination lamp and the ventilation fan in the box, and when the human body sensor is turned off, the control device Turn off the power. By turning on the illumination, the field of view of the user is secured, and the user can use the toilet bowl cleanly. Moreover, it can suppress that a bad smell is filled in a temporary toilet by the action | operation of a ventilation fan, and can maintain a temporary toilet cleanly.

According to the invention which concerns on Claim 6 , a breaker interrupts | blocks the electricity supply to a solenoid valve, a drainage pump, an illumination light, and a ventilation fan, when the electric current energized to a drainage pump becomes the predetermined value exceeding the normal operation of a drainage pump.
If the drainage system is clogged with foreign matter such as work gloves, if the sewage leaks from the filth receiving tank, the inside of the temporary toilet and the surrounding area of the temporary toilet will be dirty. Furthermore, there is concern about the occurrence of fire due to electric leakage. Therefore, when the current flowing through the drainage pump reaches a predetermined value that exceeds the normal operation of the drainage pump, the water supply by the solenoid valve opening is stopped by shutting off the electrical system, preventing the leakage of sewage from the filth receiving tank. To do. For this reason, it is possible to prevent the occurrence of fire due to electric leakage.

According to the invention which concerns on Claim 7 , a control apparatus makes a warning lamp light, when interrupting | blocking an electric system. As a result, the user can recognize that an abnormality has occurred in the temporary toilet and can take quick action such as contacting the administrator of the temporary toilet. Therefore, the temporary toilet can be kept clean.

According to the invention which concerns on Claim 8 , a temporary toilet is further provided with the liquid level sensor which detects that the water surface in a filth receiving tank becomes a predetermined | prescribed water level. When the water surface in the filth receiving tank is less than a predetermined water level, the control device lengthens the valve opening time of the primary water supply. As a result, the drainage capacity of the drainage pump can be increased by supplying sufficient water before the drainage pump is activated if the box becomes hot in summer and the amount of water in the filth receiving tank has decreased before the start of the cleaning process. Can be increased.

In subsequent S4, it is determined whether or not a predetermined time has elapsed since the human body sensor 61 was turned off. The predetermined time of S4 is set in consideration of the case where the human body sensor 61 is turned off because it cannot detect the movement of the human body even though the user is in the box. In the present embodiment, the predetermined time of S4 is set to 20 seconds, for example.
If the human body sensor is turned on within the predetermined time of S4, the process returns to S1 and the cleaning determination process is continued.
In the last S5, the control device 90 starts the cleaning process. Thereby, the cleaning determination process ends.

Next, the cleaning process will be described based on the flowchart of FIG.
When the cleaning process is started, the electromagnetic valve 42 is opened by energization from the control device 90 in the first S11, and the clean water is supplied to the toilet 30 via the water supply pipe 41. Thereby, primary water supply is started. The clean water supplied to the toilet 30 cleans the toilet and is stored in the filth receiving tank 20.
In continuing S12, the control apparatus 90 determines whether predetermined time passed since the valve opening of the electromagnetic valve 42 by S11. The predetermined time of S <b> 12 is set to a time during which the amount of clean water supplied from the water supply system 40 does not exceed a certain capacity of the filth receiving tank 20. In addition, the amount of water necessary for the discharge operation of the drainage pump 52 is set to the time for which the waste receiving tank 20 is stored. In the present embodiment, the predetermined time of S12 corresponds to the water pressure of clean water, and is set to 3 seconds, for example.
In next S <b> 13, the drainage pump 52 is activated by energization from the control device 90, and the water and excrement in the filth receiving tank 20 are discharged to the sewage facility via the drainage pipe 51 and the hose 54. Thereby, the drainage operation is started.

In continuing S14, the control apparatus 90 determines whether predetermined time passed since the valve opening of the solenoid valve 42 by S11. The predetermined time of S <b> 14 is set to a time that is the amount of water supply necessary for the toilet bowl 30 to be washed and the drainage pump to discharge the waste in the filth receiving tank 20. In the present embodiment, the predetermined time of S14 is set to 8 seconds, for example.
In next S15, the control device 90 stops energization of the electromagnetic valve 42. As a result, the electromagnetic valve 42 is closed, and the primary water supply ends.

In continuing S16, the control apparatus 90 determines whether predetermined time passed since the valve closing of the solenoid valve 42 by S15. The predetermined time of S16 is set to a time necessary for the drainage pump 52 to discharge the waste in the filth receiving tank 20.
In next S <b> 17, the solenoid valve 42 is opened by energization from the control device 90. Thereby, secondary water supply is started.
In continuing S18, the control apparatus 90 determines whether predetermined time passed since the action | operation of the drainage pump 52 by S13. The predetermined time of S18 is set to a time sufficient for the drainage pump 52 to completely discharge the water and excrement in the filth receiving tank 20. In the present embodiment, the predetermined time of S18 is set to 9 seconds, for example.
In next S <b> 19, the control device 90 stops energizing the drainage pump 52. Thereby, the draining operation is completed.

In subsequent S20, the control device 90 determines whether or not a predetermined time has elapsed since the opening of the electromagnetic valve 42 in S17. The predetermined time of S20 is set to a time during which the amount of water that can prevent the generation of malodor from the drainage system 50 can be stored in the waste receiving tank 20. In the present embodiment, the predetermined time of S20 is set to 10 seconds, for example.
In the last S21, the control device 90 stops energizing the electromagnetic valve 42. As a result, the electromagnetic valve 42 is closed, and the secondary water supply ends. The energization of the electromagnetic valve 42 may be stopped by a signal from the liquid level sensor 65.
When the secondary water supply ends, the cleaning process ends.

Next, the above-described cleaning determination process and cleaning process will be described in more detail based on the time chart of FIG.
When a user enters the box 10 of the temporary toilet 1, the human body sensor 61 is turned on at time T1 (S1). If the user leaves the box 10 without turning on the cleaning switch 62 between time T1 and time T2, the human body sensor 61 is turned off at time T2 (S3: YES). Then, the control device 90 starts the cleaning process after the time from T2 to T3 has elapsed (S4) (S5).

When the cleaning process is started, the electromagnetic valve 42 is turned on from time T3 to time T5, and primary water supply is performed (S11 to S15). Thereby, the toilet bowl 30 is washed, and the amount of water necessary for the discharge operation of the drain pump 52 is stored in the filth receiving tank 20. In addition, the control apparatus 90 may lengthen the time from T3 to T4, when it is detected by the liquid level sensor 65 that the water surface in the filth receiving tank 20 is less than a predetermined water level before the primary water supply.
At time T4 in the middle of the primary water supply, the drain pump 52 is turned on and a drain operation is started (S13). The drainage pump 52 discharges water, excrement and the like in the filth receiving tank 20 from time T4 to time T7, and is turned off at time T7 (S19). Since the drainage pump 52 discharges the sewage previously stored in the filth receiving tank 20 with the primary water supply, air is not mixed into the sewage and the impeller does not rotate freely, and the drainage capacity can be increased. For this reason, the sewage can be pumped to the sewage equipment even in an installation place with a difference in elevation, like the reverse gradient 55 of the hose 54 shown in FIG.
Since the water supply is stopped from time T5 to time T6 (S15 to S17), it is possible to save water. Further, the drainage pump 52 can completely discharge the sewage stored in advance in the filth receiving tank 20 by the primary water supply.

From time T6 to time T8, the electromagnetic valve 42 is turned on and secondary water supply is performed (S17 to S21). Thereby, clean water is supplied into the filth receiving tank 20, and it is possible to prevent the odor from being filled from the drainage system 50 into the box 10. In addition, when the temporary toilet is used next, the excrement absorbs moisture, so that the discharging operation can be easily performed.
Note that the controller 90 energizes the cleaning indicator lamp 64 from T3 to T8. The user can recognize that the cleaning process is normally performed by turning on the cleaning indicator lamp.

Next, the cleaning determination process and the cleaning process when the cleaning switch 62 is turned on will be described based on the time chart of FIG.
When the cleaning switch 62 is turned on at time T10 (S2: YES), the control device 90 starts the cleaning process (S5).
The cleaning switch 62 of this embodiment is automatically turned off at time T11 by a one-push operation. The signal of the cleaning switch 62 is input to the control device 90, and the control device 90 performs all steps of the cleaning process from time T10 to time T16. From time T10 to time T16, the same cleaning process as the cleaning process (S11 to S21) from time T3 to time T8 described above is performed.

Here, the structure of the conventional permanent toilet is shown in FIG. 10 as a comparative example.
The cleaning process for the permanent toilet 101 is performed by supplying clean water stored in the tank 4 to the toilet 5. The excrement is caused to flow to the sewage facility via the distribution pipe 6 extending downward in the vertical direction due to the water pressure supplied to the toilet 5. For this reason, the permanent toilet 101 can be discharged to the sewage facility by supplying water with a single operation that continues from the tank 4 to the toilet without having a drain pump.

On the other hand, in this embodiment, a washing process is performed by the primary water supply, drainage operation, and secondary water supply described above. (1) In the primary water supply, the toilet 30 is washed, and water necessary for the drainage operation is stored in the filth receiving tank 20. (2) The drainage operation is started from the start to the end of the primary water supply, and the sewage stored in advance in the sewage receiving tank 20 is pumped to the sewage equipment. (3) Finally, clean water is stored in the filth receiving tank 20 by the secondary water supply, and the generation of malodor from the drain pipe 51 into the box 10 is prevented. Thereby, after drainage pump 52 operates after storing sewage beforehand in filth receptacle 20 by primary feed water, it is controlled that air mixes in the sewage which the impeller of drainage pump 52 discharges. For this reason, the drainage capacity of the drainage pump 52 can be increased. Thereby, even if it is an installation place where the drainage hose 54 becomes the reverse gradient 55, it becomes possible to install the temporary toilet 1 easily. Furthermore, the temporary toilet 1 can be easily installed even in a place far from the sewage facility, for example, about 15 to 20 m.
Moreover, in this embodiment, the drainage operation is started before the end of the primary water supply, and the secondary water supply is started before the end of the drainage operation. For this reason, it is suppressed that air mixes in sewage, and the loss of the pump efficiency of the drainage pump 52 can be reduced.

  Furthermore, in this embodiment, when the user leaves the temporary toilet 1 without pressing the cleaning switch 62, the toilet 30 is cleaned in the forgetting to flow mode. In addition, the toilet 30 is cleaned by a one-push operation of the cleaning switch 62. For this reason, the temporary toilet 1 can be kept clean by automatic control without a complicated operation by the user.

  In a conventional temporary toilet, a water supply pipe and a water supply or a drain pipe and a sewage facility are connected by a pipe made of vinyl chloride resin. For this reason, when moving a temporary toilet, cutting of an envi pipe, extension processing, etc. were required. On the other hand, in this embodiment, the water supply pipe 41 and the water supply are connected by the water supply hose 43, and the drain pipe 51 and the sewage equipment are connected by the drainage hose 54. For this reason, when moving the temporary toilet 1, it is possible to move the temporary toilet 1 easily without cutting the envi-pipe, extending, or the like. In addition, the temporary toilet 1 can be easily moved because there is no need to remove filth from the toilet tub as compared with a conventional flushing-type temporary toilet.

  Furthermore, in this embodiment, the breaker 92 energizes the solenoid valve 42, the drainage pump 52, the illumination lamp 70, and the ventilation fan 80 when the current energized to the drainage pump 52 reaches a predetermined value that exceeds the normal operation of the drainage pump 52. Shut off. At this time, the warning lamp 63 is turned on by energization of the control device 90. For this reason, when the drainage system 50 is clogged with foreign matters such as work gloves, water supply to the toilet 30 can be stopped and leakage of sewage from the filth receiving tank 20 can be prevented. Therefore, it is possible to prevent the occurrence of fire due to electric leakage. In addition, the user can quickly respond by recognizing that an abnormality has occurred in the electrical system of the temporary toilet 1 such as contacting the administrator of the temporary toilet. Therefore, the temporary toilet can be kept clean.

In one embodiment mentioned above, control device 90 started drainage operation before the end of primary water supply. In addition, secondary water supply was started before the drainage operation was completed. On the other hand, this invention may start drainage operation | movement after the completion | finish of primary water supply. Moreover, you may control to start secondary water supply after completion | finish of drainage operation | movement.
In the above-described embodiment, when the user leaves the temporary toilet 1 without pressing the cleaning switch 62, the control device 90 performs the cleaning process in the forgetting to flow mode. On the other hand, according to the present invention, the cleaning process may be performed periodically in order to prevent freezing, to prevent drying of the hose and the drain pipe, or to improve maintainability.
