Abstract

There is provided a small apparatus for disposing of body wastes. The apparatus includes a stirring chamber which is connected to a discharge opening of a toilet bowl, and in which the body wastes and the absorbent are mixed together; and a rotary heating kiln which is formed together with the stirring chamber, and which has a heater for further heating and drying the mixture in the stirring chamber. The body wastes which have been heated, dried and solidified are stored in a storing portion and are collected. Thus, the apparatus is capable of quickly disposing of the body wastes, and of readily handling the solid wastes after the body wastes have been disposed, and of preventing environmental pollution.

Claims

1. An apparatus for disposing of body waste comprising:

a toilet bowl for receiving and collecting the body waste, said toilet bowl having a bottom discharge opening;

a first valve member for selectively opening and closing the bottom discharge opening of said toilet bowl and manual means for selectively operating said first valve member;

a stirring chamber located beneath said toilet bowl for receiving body waste discharged from said toilet bowl by gravity through said bottom discharge opening, a stirring element rotatably mounted in said stirring chamber, rotation means for rotating said stirring element and a stirring chamber discharge opening for discharging the body waste from said stirring chamber;

a bin for holding a particulate moisture absorbent and having a bottom discharge opening in communication with said stirring chamber for discharging said moisture absorbent into said stirring chamber wherein said moisture absorbent is mixed with the body waste by the stirring element;

rotary metering means, mounted in said bottom discharge opening of said bin, for feeding a fixed amount of said moisture absorbent into said stirring chamber responsive to operation of said manual means;

a rotary kiln in communication with said stirring chamber for receiving body waste discharged through said stirring chamber discharge opening and heating means mounted within said rotary kiln for drying the body waste received within said rotary kiln; and

a second valve member selectively movable between open and closed positions relative to the discharge opening of said stirring chamber, and means for moving said second valve member to said open position responsive to operation of said manual means.

2. An apparatus for disposing of body wastes according to claim 1, wherein said heating means is composed of a microwave generator and a microwave dielectric heating quartz tube that is heated by receiving a microwave from the microwave generator.

3. An apparatus for disposing of body wastes according to claim 1, wherein said heating means includes a dielectric heating device.

4. The apparatus of claim 1 further comprising a water-repellant coating covering the interior of at least one of said toilet bowl, said stirring chamber, and said rotary heating kiln.

5. The apparatus of claim 1 wherein said moisture absorbent is selected from the group consisting of silica gel, aluminum oxide, hydrophilic polymers, water-absorbent polymers, mineral powders and vegetable fibers.

6. The apparatus of claim 1 further comprising a collection bin for collecting dried waste discharged from said rotary heating kiln.

7. The apparatus of claim 1 wherein said heating means comprises a microwave generator which generates heat by irradiating walls of said rotary heating kiln.

8. An apparatus in accordance with claim 1 wherein said stirring chamber is inclined with respect to the horizontal and wherein said discharge opening of said stirring chamber is at an end of said stirring chamber opposite a second end of said stirring chamber which is in communication with said bottom discharge opening of said toilet bowl and wherein said stirring element serves to both mix said body waste and said moisture absorbent and to convey the resulting admixture to said discharge opening of said stirring chamber.

9. The apparatus of claim 1 wherein said bin is partially defined by wall means forming said toilet bowl, said wall means serving to separate the interior of said bin from the interior of said toilet bowl.
