【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the figure, 1 indicates a base. The base 1 is a box-shaped portion 2 fixed to a frame body 1A made of an angle member with outer plates 1B, 1B, ... It is composed of a step portion 3, and the inside of the base 1 is a storage portion 4. A partition plate 1C is provided inside the storage section 4, and the washing water tank section 5 is located above.

Reference numeral 6 denotes a building standing on the upper side of the base 1, and the building 6 is composed of a wall portion 6A, a ceiling portion 6B and a door 6C. Reference numeral 7 denotes a toilet bowl located in the building 6 and installed at the top of the base 1. The toilet bowl 7 is supplied with cleaning water in the cleaning water tank section 5 via a foot-operated pump (not shown). It is like this.

Reference numeral 8 denotes a metal disintegrating tank located below the washing water tank portion 5 and installed in the storage portion 4. The decomposition tank 8 is formed in a cylindrical shape by a bottom plate 8A, a body plate 8B, and a top plate 8C that forms an opening for a toilet, and is located near the bottom plate 8A. Is provided. The decomposition tank 8 is placed on the hexagonal support plate 10 with the upper part communicating with the toilet bowl 7. Reference numeral 11 denotes a stirring device for stirring the inside of the decomposition tank 8. The stirring device 11 includes a rotating shaft 11A projecting from the center of the bottom plate 8A into the decomposition tank 8 and a horizontal shaft which is axially separated from the rotating shaft 11A. It is composed of a pair of long stirring blades 11B and 11B and a pair of short stirring blades 11C and 11C which are fixed to each other and arranged at an angle of about 90 degrees. Reference numeral 12 is a driving device for rotationally driving the stirring device 11, and the driving device 12 is a motor 12A installed below the lifting step 3 and a rotation of the motor 12A via a transmission chain 12B. It is composed of a speed reducer 12C to which a force is transmitted, and a drive chain 12E wound between the speed reducer 12C and a sprocket 12D fixed to the rotary shaft 11A. The long and short agitating blades 11B and 11C are rotated at about 10 revolutions per minute.

Reference numeral 13 denotes a heating device for heating the inside of the decomposition tank 8. The heating device 13 is composed of a warm air heater including a heating wire and a fan, and a thermostat (not shown). The warming device 13 is located outside the decomposition tank 8 and is attached to the base 1. By blowing hot air onto the decomposition tank 8, the inside of the decomposition tank 8 is decomposed by the microorganisms that decompose human waste. The optimum temperature for activities is about 40 degrees.

Further, 14 is a control panel installed in the building 6, and the control panel 14 is a start switch for starting the motor 12A of the drive unit 12, a timer for driving for a predetermined time, and a heating device. The temperature setting switch is included. When the toilet switch is operated by the toilet user, the starting switch drives the motor 12A for 3 minutes to rotate the stirring blades 11B and 11C, and the timer keeps the stirring blades 11B and 11C in the non-rotating state for a predetermined time, for example, 1 hour. Each time, it is automatically rotated for a predetermined time, for example, 3 minutes. The temperature setting switch is operated according to the decomposition state of the human waste in the decomposition tank 8 to raise or lower the heat generation temperature of the warm air heater.

Reference numeral 15 is a human waste decomposition accelerator used to accelerate the decomposition of human waste in the decomposition tank 8 by the action of microorganisms. The human waste decomposition accelerating agent 15 is made of wood chips, and is made of wood having a diameter of 0.2 to 0.5 mm, preferably 0.2 to 0.3 mm.

The human waste decomposition accelerating agent 15 is contained in the decomposition tank 8 at about 50% of its volume.

The present embodiment is configured as described above, and the method of use is substantially the same as that of the existing simple toilet, but the toilet user operates the starter switch after use, so that the stirring blade 11B, The difference is that 11C is rotated for 3 minutes. The start switch can also be linked with the operation of the foot-operated pump for washing water. Then, the stirring blades 11B and 11C installed in the decomposition tank 8 are rotated by the control panel 14 at predetermined intervals for a fixed time, and the decomposition tank 8 containing the human waste decomposition accelerator 15 is heated by the warming device 13. It is configured to heat to the optimum temperature for decomposition. Therefore, the excrement in the decomposition tank 8 is sufficiently agitated and mixed by the excrement degradation accelerator 15 and the stirring blades 11B and 11C, and the temperature of the excrement is kept at a low temperature in which the microorganisms are active. It can be decomposed into carbon dioxide and water. At this time, most of the water generated by the decomposition evaporates, and it is almost unnecessary to drain the water through the drain pipe 9.

Although a warm air heater is used as the heating device 13 in this embodiment, a planar heating element may be attached to the outer surface of the decomposition tank 8.

It is possible to surely decompose human waste.

(2) Since human waste can be decomposed within 24 hours, it is not necessary to collect it. Therefore, if power can be supplied, it can be installed and used in any place such as outdoors, and management work is easy.

(3) Since the human waste is stored in the decomposition tank, it has a large processing capacity as compared with the conventional technology.

(4) Since human waste is decomposed into carbon dioxide gas and water, it is possible to reliably prevent generation of odor and flies. Therefore, it can always be used in a clean state and does not pollute the surrounding environment.
