Furthermore, a through-hole 43 that is normally sealed by a lid 43 a is formed at a location that is directly above the pull-out processing box 10 in the floor surface portion 1 in the toilet 100, and is formed below the through-hole 43. A bucket portion 44 having the through hole 43 as a receiving port is detachably mounted.

Next, usage examples and effects of the above-described product of the present invention will be described.
The present invention product is transported by a truck or the like to a required place such as a construction site. In addition to supplying power from the commercial power source to the power supply box 42, a water source such as a water pipe is connected to the water source connection source 31.

  The user of the present invention faces the front surface portion 2c of the toilet 100, opens and closes the door 2c1, enters the toilet 100, and uses the toilet 4 to excrete. When the excretion is completed, the user steps on the on-off valve 33 in order to allow the urine w in the toilet 4 to flow, so that the urine w is washed with about 200 cc of rinsing water from the urine dropping cylinder 4c of the toilet 4 and the lower end thereof. The check valve body 4d attached to is pushed open and falls into the pull-out type processing box 10. When such a use is performed by a large number of people, the urine w or the like is accumulated in the pull-out processing box 10 and the air ejection means 12 is covered with the urine w or the like. In this state, the blower 24 is automatically started to operate or is manually operated.

  When the blower 24 starts to operate, the outside air in the toilet 100 is supplied to the air ejection means 12 and is ejected vigorously from a large number of fine through holes, and the ejected air is drawn out of the pull-out processing box 10. The urine w accumulated inside is vigorously stirred and oxygen is supplied to the aerobic microorganisms in the urine w. On the other hand, the operation of the sirocco fan 21 causes the outside air in the toilet 100 to be continuously blown from the upper side to the entire surface of the urine w or the like accumulated in the pull-out type processing box 10 through the duct 25, and the temperature of the urine w When the temperature reaches 27 ° C., the rod-shaped temperature sensor 34d detects this and starts energizing the electric heater 13, and when the temperature of the urine w reaches 30 ° C., the rod-shaped temperature sensor 34d detects this and The energization of the heater 13 is stopped, whereby the urine w in the pull-out processing box 10 is heated within a range of approximately 27 ° C. to 30 ° C., and thereby the aerobic microorganism in the urine w Since the oxygen is sufficiently supplied to activate the activity, the urine w and the like are rapidly decomposed by the aerobic microorganisms and are effectively transpirationed by the heat of the electric heater 13. .

  At this time, the amount of transpiration such as urine w is, for example, about 40 to 50 liters per day. Therefore, even if an adult uses about 40 liters, the amount of urine w or the like in the pull-out processing box 10 Therefore, it is not necessary to pump out the urine w in the pull-out type processing box 10 at such a usage amount.

If such use is performed over a long period of time, the manure w in the drawer-type processing box 10 gradually increases in solid content and becomes thicker. In order to cope with this, usually, for example, the following wrinkle removal process of the urine w is performed every 2 to 4 months, that is, the lid 43a of the floor surface portion 1 is removed and the inside of the bucket portion 44 is removed. After a bag-like filter (which may be a commercially available product) is inserted into an unfolded state, the urine w in the pull-out type processing box 10 is pumped onto the floor surface portion 1 with an impeller-type pump that is separately prepared. Through the bag-shaped filter. Thereby, the solid content of the urine w in the pull-out type processing box 10 is squeezed out to the inside of the bag-like filter, and the liquid content permeates the peripheral wall surface of the bucket portion 44 to the inside of the pull-out type processing box 10. Therefore, after the scouring process, the urine w in the drawer-type processing box 10 has a low solid content and is excellent in fluidity. The bag-like filter after the scouring process is discarded together with the solid content accumulated inside thereof, and the through hole 43 is closed with a lid 43a.
Each time the drawer-type processing box 10 is used for about one year, the inside is washed with water to remove the residue.

  When the drawer-type processing box 10 is washed, the use of the product of this embodiment is temporarily stopped to completely evaporate the liquid content in the drawer-type processing box 10. A thin dry sludge is attached to the inner bottom surface 10a, and this dry sludge has almost no weight and a very low bulk.

  After this processing, the operator cuts off the power supply to the power supply box 42, then removes the door body b12 of the opening / closing port b1 of the front surface portion 6c of the first one-side box body 101a, The pull-out processing box 10 is supported and guided by the ring body 16 and the raceway plate member 17 and is smoothly pulled out horizontally forward by placing a hand on the front end portion and applying a pulling force. When the drawing amount reaches a specific size, the tip of the hose 14 is detached from the coupling member a1, and the heater power supply line 13a extended from the electric heater 13 is detached from the connector a2. Next, the operator pulls out the pull-out type processing box 10 further horizontally and pulls it out from the manure processing chamber 8. Then, instead of the drawn-out processing box 10 that has been extracted, another clean-up-type processing box 10 that has been prepared in advance is mounted in the manure processing chamber 8 by a reverse operation at the time of removal. Thereafter, the power supply to the power supply box 42 is resumed to return to the usable state.

  On the other hand, the pull-out processing box 10 extracted from the manure processing chamber 8 is transported to a specific cleaning place by a truck or the like, and here, dry sludge and the like adhering to the inside of the pull-out processing box 10 is washed with water. . At this time, in the transport of the drawer-type processing box 10 by the truck, the drawer-type processing box 10 is small and light, and the sludge in the drawer-type processing box 10 is dry and its amount is very small. It requires less labor for transportation and is easy to handle because it is not subject to legal regulations related to manure treatment, and the upper surface of the drawer-type processing box 10 is opened for cleaning the drawer-type processing box 10. Therefore, the inside can be cleaned without difficulty. The drawer-type processing box 10 thus cleaned is stored for the next use.

In the present embodiment, the outside air sent out from the blower 24 is sent to the air jetting means 12 and is jetted out radially from the porous wall surfaces of the four diffusers 12a. At this time, each diffuser 12a is inclined in a plan view with respect to the peripheral wall surface 10b of the pull-out type processing box 10, and air is blown out radially around the entire circumference. Therefore, the diffuser 12a is stored higher in the pull-out type processing box 10 than the diffuser 12a. Therefore, the aerobic microorganisms in the urine w are sufficiently supplied with oxygen by supplying a relatively small amount of outside air, and the activity is activated. Quickly disassemble.
It has been confirmed by experiments by the inventors that the stirring action of the liquid in the drawer-type processing box 10 is greatly reduced when the inclination angle θ of each diffuser 12a is made zero.

  Since the outside air sucked into the sirocco fan 21 flows into the upper sealed space 9b through the vent hole c3 and the vent hole c4, and then flows into the lower sealed space 9a through the vent hole c5b, the blower 24 flows into the outside air. The outside air sent into the urine processing chamber 8 by the sirocco fan 21 is heated by the heat generated by the blower 24. At this time, the heated outside air warms the inside of the manure processing chamber 8 and promotes the decomposition treatment of the manure w by microorganisms.

  When the outside air is supplied into the urine processing chamber 8 by the sirocco fan 21 or the blower 24, the air (odor) in the urine processing chamber 8 is pushed and the second rectangular box body 101b of the second rectangular box body 101b is pushed through the circular vent hole c1 of the rear surface portion 6d. It flows into the lower range and the right half range d2, and flows as shown by an arrow f3 in FIG. On the other hand, the motor-driven axial fan 23 is operated to allow outside air to flow into the lower sealed space 9a through the outside air flow inlet c5a and the like, and to the inside of the right half range d2 of the second rectangular box 101b through the vent c7. The outside air flowing in this way is converted into negative ions by the negative ion generator 26. The negative ions thus generated are mixed and stirred with the odor in the right half range d2 of the second rectangular box 101b, and the right half of the second rectangular box 101b together with the deodorized air while removing odor components from the odor. The air that moves up and down as described above flows into the exhaust pipe 38 while being sterilized by being irradiated with ultraviolet rays or the like by the sterilizer 37 and reaches the activated carbon tank 39 when it reaches the activated carbon tank 39. It is contacted and subjected to a final deodorization treatment, and then released to the outside.

  When the human body is not excreted for a relatively long period under the operating state of the product of this embodiment, the amount of manure w in the pull-out processing box 10 is less than the allowable amount, that is, from the surface of manure w If the depth to the bottom surface 10a is not sufficient to supply oxygen to the aerobic microorganisms, for example, 50 mm or less, it may become unusable. The sensor 34 detects the state, opens the electromagnetic open / close valve 35a, and supplies water to the inside of the pull-out processing box 10 through the water supply pipe 35b so that the depth exceeds 50 mm. When a specific amount of water is supplied and the depth of the urine w exceeds 50 mm by a specific length, the urine sensor 34 detects this state and closes the electromagnetic on-off valve 35a. . As a result, the depth of the manure w in the drawer-type treatment box 10 is automatically maintained at 50 mm or more, oxygen supply by the air ejection means 12 to the aerobic microorganisms is effectively performed, and the ability to decompose manure w Is kept high, and it is avoided that the product of this embodiment falls into an unusable state.

  In addition, when the temperature of the outside air decreases excessively (for example, to 3 ° C. or lower) under the operating state of the product of this embodiment, the outside air supplied from the duct 25 into the manure processing chamber 8 is excreted in the drawer type processing box 10. Since w is cooled and the temperature is lowered, the decomposition process of the urine w by microorganisms is not actively performed. In order to prevent this, the outside air has become 3 ° C. or lower in this embodiment. When this is detected by the temperature sensor 29, energization of the electric heaters 28, 28 is started, and when the outside air reaches 13 ° C., this is detected by the temperature sensor 29 and applied to the electric heaters 28, 28. Therefore, the temperature of the urine w in the pull-out processing box 10 is not excessively lowered, and the decomposition of the urine w by microorganisms is actively performed even in a place where the outside air is 3 ° C. or less, Process as planned A force is exerted.

In the above embodiment, it is optional to control the power supplied to the electric heaters 28 and 28 in relation to the temperature of the outside air. The temperature sensor 29 may be provided in the manure processing chamber 8.
When the toilet 4 is changed from the Japanese style to the Western style, the high floor 18 and the toilet bowl 4 are removed, and a Western style toilet bowl is fixed instead.
