BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) Hereinafter, an embodiment of a human waste disintegrating toilet according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a partially disassembled human waste decomposition type toilet 10 of this embodiment. FIG. 2 (a) is a horizontal sectional view including the human waste decomposition tank 12 of the human waste decomposition type simple toilet 10, and FIG. 2 (b) is a vertical sectional view including the human waste decomposition tank 12 of the human waste decomposition type toilet 10. It is.

As shown in FIG. 1 and FIG. 2, a human waste disassembling type toilet 10 of the present embodiment comprises a building 11 and a human waste decomposition tank 12.
, A stirring device 13 and a control device 14. Hereinafter, the components of the human waste decomposition type portable toilet 10 of the present embodiment will be sequentially described.

[Building 11] The human waste decomposition type portable toilet 10 of the present embodiment has a building 11. The building 11 is constructed in a designed desired shape by appropriately using steel, wood, reinforced plastic or a combination thereof.

At the front of the building 11, there are doors 11a for access.
Is attached to open and close freely. In addition, a step 11b is provided at the lower front part of the building 11 to enter the inside of the building 11.

A table 15 is disposed on the floor 11c of the building 11, and a Japanese toilet 16 is mounted on the upper surface of the table 15 in the present embodiment. The toilet bowl 16 is not limited to a Japanese style but may be a Western style. A mat 17 having a built-in load detector is mounted on a table 15 around the toilet bowl 16. In the case of a Japanese-style toilet, the mat 17 detects a load caused by the presence of a person, while in the case of a Western-style toilet, a load detector is incorporated in the toilet 14 to detect this load.

The mat 17 is connected to a control device 14 to be described later, and controls the start or stop of the stirring device 13 via the control device 14. Specifically, the stirring device 13 described below is stopped while the mat 17 is detecting the load, and the stirring device 13 is activated only while the mat 17 is not detecting the load. Thus, even if the foot is accidentally dropped from the toilet bowl 16 into the human waste decomposition tank 12 at the time of use, the agitation device 13 remains stopped, so that the occurrence of injury is completely eliminated.

Further, the stirrer 13 is automatically activated when the user descends from the mat 17 after use, so that excrement can be accelerated without requiring the user to perform troublesome operations of starting and stopping the stirrer 13. Generation of offensive odor due to continued mounting without stirring on the agent can be reliably prevented.

On the floor 11c of the building 11, rails 18a and 18b for putting in and out the human waste decomposition tank are laid. The human waste decomposition tank 12 described below is movably arranged by being guided by the human waste decomposition tank entrance / exit rails 18a and 18b. The fixed position of the human waste decomposition tank 12 is below the table 15 and the toilet bowl 16.

It is to be noted that a second space of the human waste decomposition tank 12 to be described later is used.
One end of a pipe 19 for discharging an odor generated by urine contained in the second space 24 communicates with 24. The other end of the pipe 19 is connected to a ventilation fan 20 provided on the ceiling of the building.
Thereby, the odor generated by urine stored in the second space 24 is exhausted to the outside through the pipe 19 and the ventilation fan 20, and the discomfort caused by the bad odor in the building 11 is eliminated.
In the present embodiment, the building 11 is configured as described above.

FIG. 3 is a perspective view of the human waste decomposition tank 12 used in the simple human waste decomposition type toilet 10 of the present embodiment, which is extracted and partially omitted.

The human waste decomposition tank 12 stores excrement therein through the opening 21.

The human waste decomposition tank 12 is divided into a first space 23 and a second space 24 by a partition wall 22. The partition wall 22 has a large number of through holes 22a. Thereby, the first space
Of the human waste discharged into 23, only urine is contained in many through holes 22
It is led to the second space 24 via a. That is, the partition
Reference numeral 22 has a function of separating only urine from the human waste accommodated in the first space 23 into the second space 24.

The first space 23 is a space for decomposing feces of human waste. For this reason, the first space 23 contains a human waste decomposition promoter (not shown) in advance. As the human waste decomposition promoter, any substance can be used as long as it has a function of decomposing human waste, but in the present embodiment, it is a porous substance such as a wood strip treated with microorganisms that decompose human waste. In this case, the chemical composition varies depending on the type of the raw wood, but it is desirable that the content is 60 to 65% by weight of cellulose, 15 to 25% by weight of lignin, 10 to 15% by weight of bentozan, and 11 to 16% by weight of moisture. It is desirable that the porous material such as woody strips to which microorganisms are applied be introduced so as to occupy about 40 to 50% of the volume of the first space 23.

The second space 24 is a urine storage tank for storing urine of human waste. For this reason, the bottom of the second space 24 is formed at a position lower than the bottom of the first space 23. Thereby, in the second space 24, through the partition wall 22,
Urine and washing water can be easily and reliably stored.

As shown in FIG. 2A, a sensor 25 for detecting the temperature inside the first space 23 is mounted on a wall inside the first space 23. The output value of the sensor 25 is sent to the control device 14. In addition, as shown in FIG.

The first heating device 26 has a capability of heating the temperature inside the first space 23 to about 40 degrees, which is the optimum temperature for promoting the activation of microorganisms. The first heating device 26 is controlled by a control signal from the control device 14.

The temperature inside the first space 23 is detected by the sensor 25, and when this temperature falls to a preset lower limit, a control signal from the control device 14 to the first heating device 26 is output. Then, the temperature inside the first space 23 is controlled to be equal to or higher than the lower limit value. Then, when the temperature inside the first space 23 rises and rises to a preset upper limit value, a control signal is output from the control device 14 to the first heating device 26, and the first The heating device 26 is turned off. Such a sensor
25, by performing control using the first heating device 26 and the control device 14, the temperature inside the first space 23 is stably maintained in the appropriate temperature range for activating microorganisms.

As shown in FIG. 2B, the first space
A humidity detector 27 for detecting the humidity inside the first space 23 is mounted in the immediate vicinity of the opening 21 of 23. The output value of the humidity detector 27 is sent to the control device 14.

The water supply device 30 is a control device
It is controlled by the control signal from 14.

The humidity inside the first space 23 is detected by the humidity detector 27, and when this humidity drops to a preset lower limit, a control signal is output from the control device 14 to the water supply device 30. Then, a shower is spouted from the water supply nozzle 31 toward the inside of the first space 23 to control the humidity inside the first space 23 to a lower limit or more. Then, when the humidity inside the first space 23 rises and rises to a preset upper limit value, a control signal is output from the control device 14 to the water supply device 30, and the water supply device 30 is turned off. You. By performing such control using the humidity detector 27, the water supply device 30, and the control device 14, the humidity inside the first space 23 is controlled to a predetermined value. For this reason, it is possible to surely prevent scattering of the excrement of the human urine decomposition due to the pulverization and drying during long-term operation, and occurrence of a fire caused by, for example, a cigarette fire igniting the pulverized and dried excrement of the human urine.

As shown in FIG. 2A, a water level gauge 32 is provided in the second space 24, and the amount of urine and water stored in the second space 24 is detected. The output signal of the water level gauge 32 is
Connected to control device 14. Further, a second heating device (not shown) is mounted on the bottom of the outer surface of the second space 24. The second heating device is a heater that heats the second space 24 to evaporate the liquid stored in the second space 24. The second heating device (not shown) is controlled by a control signal from the control device 14.

The level of the liquid contained in the second space 24 is detected by the water level gauge 32, and when the level of the liquid rises to a preset upper limit value, the control device 14 controls the second heating device. A signal is output and the second heating device is switched to the second space.

The air is exhausted outside through Then, when the water level of the liquid contained in the first space 24 drops and the output from the water level gauge 32 stops, a control signal to the second heating device is output from the control device 14 and the second heating device The device is turned off. By performing such control using the water level gauge 32, the second heating device, and the control device 14, the water level of the liquid stored in the second space 24 is controlled within a predetermined range. Therefore, the urine stored in the second space 24 can be easily and cleanly processed.

After use, the water supply device 30 is automatically turned on, and a suitable amount of water is washed in the first space 23. In the present embodiment, the human waste decomposition tank 12 is configured as described above.

[Stirring Device 13] As shown in FIGS. 1 to 3, the human waste decomposition tank 12 is provided with a stirring device 13. The stirrer 13 is configured to stir the excrement of the excrement and the excrement accommodated in the excrement tank 12 by rotating about a rotation shaft 33 extending substantially horizontally inside the excrement tank 12.

In this embodiment, a driving device 36 that can rotate the rotating shaft 33 in both directions is attached to one end of the rotating shaft 33. The drive device 36 is an electric motor with a speed reducer, and is driven by a drive signal from the control device 14 to be described later.
33 is rotated at a rotational speed of about 5 revolutions per minute. As described above, the load detection signal from the mat 17 is transmitted to the control device.
While being output to 14, the driving device 36 stops.

In the present embodiment, the rotating shaft 33 does not rotate 360 degrees but, as shown in FIG.
It reciprocates in the range θ of about 180 to 220 degrees. This allows
The human waste and the human waste decomposition promoter can be sufficiently stirred and mixed while the height of the first space 23 is suppressed as much as possible. If there is enough space in the installation space of the first space 23 and the height of the first space 23 can be sufficiently secured,
You may make it rotate more than this range (theta).

Agitating blades 37a to 37d are attached to the rotating shaft 33 so as to be directed substantially perpendicular to the axial direction. In the longitudinal section, the stirring blades 37a and 37b and the stirring blade 37
c and 37d are arranged so as to be substantially orthogonal to each other. In the present embodiment, the stirring blades are arranged in two rows in the axial direction of the rotary shaft 33, but the invention is not limited to this, and one or three or more rows may be provided.

Further, each of the stirring blades 37a to 37d has a blade surface inclined so as to have an angle with respect to the rotation direction to improve the stirring effect. in this way,
In the present embodiment, each of the stirring blades 37a to 37d, which are driven to rotate in both directions together with the rotating shaft 33, can sufficiently stir and mix the night soil and the night soil decomposition accelerator contained in the night soil decomposition tank 12.

[Control Device 14] A control device 14 is mounted on the front wall inside the building 11. On the front of the control device 14,
An energizing lamp, an ammeter, a failure indicator lamp, and the like are attached so that the operating status of each facility of the urine disassembly-type simple toilet 10 can be grasped at a glance. The control device 14 has a built-in operation timer, a temperature control device, a humidity control device, and the like.

The control device 14 of the present embodiment is configured as described above.

Next, such a building 11 and a human waste separation tank 12
The operation of the sewage disassembly-type simple toilet 10 of the present embodiment including the stirring device 13 and the control device 14 will be described. During normal operation, the urine disassembly-type simple toilet 10 of the present embodiment is automatically operated by the control device 14 in the order listed below.

(A) The user opens the door 11a and opens the building 11
Go inside and close door 11a. At this time, the stirring device 13 is still being driven to rotate, but when the user steps on the mat 17 placed on the table 15, a load detection signal is output from the mat 17 to the control device 14. For this reason, the control device 14
A stop signal is output to 13, and the stirring device 13 stops.

(B) When the user gets off the platform 15 and separates from the mat 17 after use, a drive signal is output from the control device 14 to the stirring device 13 at intervals of about 5 minutes from this time. Is done.

(C) At this time, the control device 14
After outputting the drive signal to the first heating device 26 and the second
A drive signal is output to the heating device, and both the first space 23 and the second space 24 are controlled to an appropriate temperature for several hours. As a result, the human waste is decomposed by the human waste decomposition accelerator contained in the human waste decomposition tank 12 reliably.

The driving and control of the water supply device 30 are stopped in accordance with a control signal from the control device 14 corresponding to an output signal from the humidity detector 27. The water supply device 30 is driven irrespective of the driving states of the stirring device 13, the first heating device 26, the second heating device, and the like.

(D) When the user gets off the platform 15 and separates from the mat 17 after use, the water supply device 30 is activated just once and water is supplied to the first space 23, and the water is washed. Is done. The amount of water to be supplied is set to 200 to 300 cc, for example, by setting a supply time per one time with a timer.

Thus, the human waste and the human waste decomposition accelerator contained in the human waste decomposition tank 12 are sufficiently stirred and mixed,
The action of microorganisms that decompose human waste is activated, and the human waste is decomposed into carbon dioxide and moisture approximately one day and night, and the water evaporates and disappears with the carbon dioxide gas.

As described above, since human waste is decomposed and vaporized, the environment around the installation position is not polluted, and the wastewater processing capacity can be continuously maintained only by appropriately replenishing the consumed water and porous material. it can.

(E) If the next user is not present for more than 2 hours, for example, after completing step (d), the control device 14 sends the agitation device 13, the first heating device 26, the water supply device 30, A stop signal is output to each of the second heating devices, and a load detection signal from the mat 17 is input to each of the stirring device 13, the first heating device 26, the water supply device 30, and the second heating device. Pause in a standby state until For this reason, exhaustion and powdering of the human waste decomposition promoter can be prevented.

As described above, according to the human waste decomposition type portable toilet 10 of the present embodiment, the following effects (i) to (vi) are listed.
i) is played. (i) Even if an infant or the like accidentally steps on the urine disintegrating tank 12 from the toilet 16, the rotary wings 37 a to 37 d rotate only about 1/4 of the vertical direction, so there is a great risk of serious injury to the foot. Reduced.

(Ii) Since the electric motor 36 with a speed reducer is directly coaxially connected to one end of the rotating shaft 33, periodic maintenance for preventing poor rotation of this drive system is required.
Almost no need to do this. For this reason, the maintainability is significantly improved.

(Iii) Since the plurality of rows of stirring blades 37a to 37d are arranged in the axial direction of the rotating shaft 33 extending in the horizontal direction, the night soil and the night soil decomposition accelerator contained in the night soil decomposition tank 12 are added to the site. It is possible to stir evenly without depending. For this reason, it is possible to prevent a local decrease in the rate of decomposition of human waste caused by non-uniform stirring.

(Iv) Bearings 35a and 35b that support the rotating shaft 33
However, since it is arranged at a relatively high position in the human waste decomposition tank 12 and is a position where foreign matter is hardly mixed, poor rotation of the rotating shaft 33 due to the mixed foreign matter hardly occurs.

(V) The human waste decomposition tank 12 is partitioned by a partition 22 by a first space 23 and a second space 24, feces are decomposed by the first space 23, and urine is decomposed by the second space 24. Since evaporation is performed, even when washing is performed, the treatment can be performed in the first space 23 at a moisture concentration that is optimal for the treatment of human waste with the human waste decomposition promoter.

(Vi) The humidity inside the first space 19 is detected by the humidity detector 27, and water is supplied from the water supply device 30 in accordance with the detected value. In addition, it is possible to reliably prevent scattering due to drying, and the occurrence of a fire caused by, for example, a cigarette fire igniting the pulverized and dried human waste decomposition promoter. (vii) Since control is automatically performed using the control device 14, generation of offensive odor or the like due to improper operation of the user does not occur.

As described above, the human waste disintegrating toilet 10 of the present embodiment improves the safety of the user and prevents equipment failures and accidents as much as possible, whereby the human waste is removed by the action of microorganisms. It can be efficiently and reliably decomposed to water and carbon dioxide over a long period of time, and furthermore, no pumping is required.
