BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a closet, and particularly relates to a waterless closet that does not need water to flush.
BACKGROUND OF THE INVENTION
The prior art toilet and closet need water to flush. Once there is no water or there is not enough water, it will cause serious environmental pollution. Accordingly, the prior art toilet and closet are not suitable for use in a waterless place, in a place lacking water or in a movable toilet.
To improve the prior art closet, U.S. Pat. No. 4,025,969 disclosed a sanitary closet that may be cleaned automatically without using water. This closet consists of a closet, a transmission case under the closet and a disposal container. There are two guiding wheels located inside the transmission case, which are used to feed downwards and tightly close a plastic hose, each of the wheel may rotate in opposite direction respectively. A tube-shaped plastic hose goes into the upper entrance of the closet from the bottom of an annular seat fixed on the top of the closet, and then through the guiding wheels and the entrance of the disposal container gets into the disposal container. The drawback of the prior art is that the annular seat can not meet the requirements of sanitation and likely causes cross infection among users.
THE SUMMARY OF THE INVENTION
Therefore, the objective of this invention is to provide a waterless closet assembly that needs no water and can meet the requirements of sanitation.
The waterless closet assembly in accordance with the present invention includes a closet having an upper entrance, a lower exit, an annular seat located on the top of the upper entrance, a long tube-shaped plastic hose, and a step-by-step feeding device. One end of the plastic hose is located outside the closet. The other end of the plastic hose goes over the upper surface of the annular seat, passes through the inside of the inlet of the closet and the step-by-step feeding device, and then is fed into the disposal container from its entrance.
After each use of the closet, the step-by-step feeding device feeds the used section of the plastic hose into the disposal container and a new section of the plastic hose is then put on the annular seat to keep the closet clean and to prevent the users from cross infection.
The further merits and details of this invention are given with reference to the accompanying drawings.
