Temporary toilet

Abstract

A compact and easily transportable temporary flush toilet can be installed where the toilet cannot be connected to a water supply system and no frequent maintenance is possible. The temporary toilet includes a toilet bowl, a flush water tank for storing flush water used to flush the toilet bowl, a sewage tank for storing sewage from the toilet bowl, a water vapor separator for separating water from gas containing water vapor vaporized from sewage in the sewage tank, an exhaust pipe through which gas is guided from the top of the sewage tank to the water vapor separator, and a distilled water pipe through which water separated from the gas in the water vapor separator is supplied to the flush water tank. Thus, storage of the sewage, microbial decomposition of waste, and evaporation of the sewage take place in the sewage tank alone.

1 . A temporary toilet comprising a toilet bowl, a flush water toilet which keeps flush water to be supplied into the toilet bowl, a sewage tank which keeps sewage discharged from the toilet bowl, a water vapor separator capable of separating water from a gas containing a water vapor which has been evaporated in the sewage tank, an exhaust pipe through which a gas is guided from a top of the sewage tank to the water vapor separator, and a water supply pipe through which water separated in the water vapor separator is supplied into the flush water tank,
 wherein storage of sewage, microbial decomposition of waste, and evaporation of sewage take place in the sewage tank only.   
     
     
         2 . The temporary toilet of  claim 1 , further comprising a blower diffuser tube provided in the sewage tank and capable of discharging a gas which agitates sewage in the sewage tank. 
     
     
         3 . The temporary toilet of  claim 1 , further comprising a heater provided in the sewage tank and capable of heating sewage in the sewage tank. 
     
     
         4 . The temporary toilet of  claim 3 , wherein the heater is capable of heating the sewage in the sewage tank to a temperature of 25° or higher and 30° C. or lower, and wherein the temporary toilet further comprises a control unit configured to deactivate the heater when the temperature of the sewage reaches a predetermined upper limit. 
     
     
         5 . The temporary toilet of  claim 1 , further comprising a floating water level sensor provided in the sewage tank so as to be movable in the sewage tank as the level of sewage in the sewage tank, a switch connected to the floating water level sensor, wherein the floating water level sensor and the switch are configured such that the switch is opened or closed when the level of the sewage in the sewage tank rises to a predetermined level, and a use prohibition display provided outside of the toilet and configured such that the indication on the display changes to indicate that the toilet cannot be used when the switch is opened or closed. 
     
     
         6 . The temporary toilet of  claim 1 , further comprising a solar cell panel and a battery for storing electricity generated by the solar cell panel, wherein the electricity generated by the solar cell panel constitutes a total electricity consumed by the toilet. 
     
     
         7 . The temporary toilet of  claim 2 , further comprising a heater provided in the sewage tank and capable of heating sewage in the sewage tank. 
     
     
         8 . The temporary toilet of  claim 2 , further comprising a floating water level sensor provided in the sewage tank so as to be movable in the sewage tank as the level of sewage in the sewage tank, a switch connected to the floating water level sensor, wherein the floating water level sensor and the switch are configured such that the switch is opened or closed when the level of the sewage in the sewage tank rises to a predetermined level, and a use prohibition display provided outside of the toilet and configured such that the indication on the display changes to indicate that the toilet cannot be used when the switch is opened or closed. 
     
     
         9 . The temporary toilet of  claim 3 , further comprising a floating water level sensor provided in the sewage tank so as to be movable in the sewage tank as the level of sewage in the sewage tank, a switch connected to the floating water level sensor, wherein the floating water level sensor and the switch are configured such that the switch is opened or closed when the level of the sewage in the sewage tank rises to a predetermined level, and a use prohibition display provided outside of the toilet and configured such that the indication on the display changes to indicate that the toilet cannot be used when the switch is opened or closed. 
     
     
         10 . The temporary toilet of  claim 4 , further comprising a floating water level sensor provided in the sewage tank so as to be movable in the sewage tank as the level of sewage in the sewage tank, a switch connected to the floating water level sensor, wherein the floating water level sensor and the switch are configured such that the switch is opened or closed when the level of the sewage in the sewage tank rises to a predetermined level, and a use prohibition display provided outside of the toilet and configured such that the indication on the display changes to indicate that the toilet cannot be used when the switch is opened or closed. 
     
     
         11 . The temporary toilet of  claim 2 , further comprising a solar cell panel and a battery for storing electricity generated by the solar cell panel, wherein the electricity generated by the solar cell panel constitutes a total electricity consumed by the toilet. 
     
     
         12 . The temporary toilet of  claim 3 , further comprising a solar cell panel and a battery for storing electricity generated by the solar cell panel, wherein the electricity generated by the solar cell panel constitutes a total electricity consumed by the toilet. 
     
     
         13 . The temporary toilet of  claim 4 , further comprising a solar cell panel and a battery for storing electricity generated by the solar cell panel, wherein the electricity generated by the solar cell panel constitutes a total electricity consumed by the toilet. 
     
     
         14 . The temporary toilet of  claim 5 , further comprising a solar cell panel and a battery for storing electricity generated by the solar cell panel, wherein the electricity generated by the solar cell panel constitutes a total electricity consumed by the toilet.
