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.

Description

TECHNICAL FIELD[0001]The present invention relates to a flush toilet which can be continuously used without supplying additional water from outside.BACKGROUND ART[0002]Toilets are essential in order to maintain hygiene of an environment where humans live. In order to maintain high standards of living where the population density is high, flush toilets are indispensable, instead of toilets of the type which are eventually simply dumped into the environment. But in rural communities which are far from cities and cannot afford to construct a sewage system, toilets are often used having a sewage treatment tank in which waste is decomposed utilizing microorganisms. It is also being considered to use sewage as flush water for flush toilets so that flush toilets can be installed in areas where it is difficult to construct a water supply system.[0003]For example, Patent document 1 discloses a heating / evaporation type toilet system including a flow type waste tank in which waste from a toile...

Benefits of technology

[0018]The temporary flush toilet according to the present invention can be installed at any location where there is neither a water supply system nor a sewage system, because the toilet according to the invention can be used for an indefinite period of time without the need for any willful supply of water from outside. Once installed, this toilet is virtually maintenance-free. But if it is desirable or necessary, water such as rainwater may be supplied from outside, for example, if a large amount of flush water is consumed during a short period of time.

[0019]Specifically, the toilet according to the present invention can be installed on riverbeds, in cam

Problems solved by technology

While the toilet system disclosed in either of Patent documents 1 and 2 can sufficiently deodorize and decolor waste produced, it is large in size.

Thus, the treatment mechanism of this toilet system, including treatment tanks, is inevitably larger in size than the toilet body itself.

There are a large number of component parts that need periodical maintenance.

It is therefore troublesome and time-consuming both to install this toilet system and to maintain it.

For these reasons, neither of these toilet systems can be installed in areas where once the toilet system is installed, it has to be left unattende
