The exhaust fan 21 has a first blower 7 and a second blower.
The blower 16, the blower section of the heating device 12, and the blower 13 are set to have an exhaust amount larger than the total blown amount.

Next, the electric circuit of this embodiment will be described with reference to FIG. Reference numeral 22 is a control circuit for inputting outputs from the water level detection unit 19, the heater temperature detection unit 23, and the outside air temperature detection unit 24. The first blower 7 and the second blower 1
6, the blower 13, the heater 17, the exhaust fan 21, the heating device 12, and the alarm device 25 are controlled.
The alarm device 25 is composed of a buzzer, a display device arranged in a toilet, and the like, and issues an alarm when the water level detection unit 19 detects the storage upper limit position.

The discharged human waste passes through the connecting pipe 2 and is temporarily accumulated in the J-shaped pipe 3, where the urine is mixed as toilet paper, and when the amount of human waste is increased, it is mixed from the J-shaped pipe 3 into the stirring tank 1. It fits and urine overflows. The human waste collected in the agitation tank 1 is agitated by the air supply from the first blower 7 connected to the first air supply pipe 5 and is supplied with oxygen, and is polluted by the activity and chemical reaction of aerobic bacteria. The gas such as carbon dioxide and water vapor generated by pre-decomposing the gas are forcibly exhausted by the exhaust fan 21 from the first exhaust port 8.

Since the agitation tank 1 is stored up to the height of the excrement urine outflow pipe 10 provided on the side wall of the agitation tank 1, the excrement collected in the agitation tank 1 is preliminarily decomposed until it overflows into the treatment tank 9. The sufficiently pre-decomposed human waste overflows when it reaches the height of the human waste outflow pipe 10 and flows into the treatment tank 9.

The sewage flowing into the treatment tank 9 is supplied with air from the second blower 16 connected to the second air supply pipe 14 to supply oxygen into the sewage, and decomposed by the activity and chemical reaction of aerobic bacteria. To do.

Further, the pre-decomposed human waste is the water level detection unit 1
When the storage lower limit position of 9 is reached, the heater 17 is controlled to maintain the urine temperature in the treatment tank 9 within the range of 15 to 40 degrees Celsius, which is the optimum temperature for the activity of aerobic bacteria. Drive it and blow air to the urine surface.

By this air blow, gas such as carbon dioxide generated by the decomposition of urine is generated as bubbles covering the human urine surface generated by the supply of air from the second supply pipe 15 to scatter the oxygen deficiency. In addition to preventing the aerobic bacteria from dying out, a large amount of oxygen is also supplied from the liquid surface of the black urine to further activate the activity and chemical reaction of the aerobic bacteria and further enhance the decomposition of human urine.

In winter, since the outside air temperature is low, the temperature of the human waste decreases due to the air blown from the blower 13 to the liquid surface of the human urine, the activity of aerobic bacteria decreases, and the efficiency of human waste treatment deteriorates. In the embodiment, when the outside air temperature detection unit 24 detects a temperature of 15 degrees Celsius or less, the heating device 12 is controlled to supply the warm air to the blower tube 11, and the blower tube 11 blows the warm air at about 25 degrees Celsius. By blowing air on the surface of urine, the activity of aerobic bacteria is promoted regardless of the season.

During a long trip, the inflow of the pre-decomposed human waste into the treatment tank 9 is temporarily stopped. In such a case, the water level detector 19 in the treatment tank 9 detects the storage lower limit position, The power of the blower 13 is turned off by the control of the control circuit 22 to prevent the decrease in the water level of human waste. Furthermore, when the temperature detection unit 23 of the heater 17 is exposed to human urine, the heat from the heater 17 is directly detected, and the power of the heater 17 is cut off by the control of the control circuit 22 to prevent abnormal heating, thereby preventing the processing tank. Suppress evaporation of human waste in 9.

Further, even when the water level of human waste is below the lower limit of storage, the supply of air from the second blower 16 maintains the activity and chemical reaction of aerobic bacteria and continues the decomposition.

Although the stirring tank 1 and the processing tank 9 are provided in the first embodiment, the stirring tank 1 may be omitted and the discharged human waste directly flows into the processing tank 9.

In the first embodiment, the heating device 12 is installed near the blower tube 11 to supply the warm air into the blower tube 11. However, the heating device 12 is installed in the blower tube 11 and inside the blower tube 11. Alternatively, the heating device 12 may be installed near the air outlet of the air blower 11 to heat the air blown from the air blower 11 into the processing tank.

FIG. 4 shows a second embodiment of the present invention, in which the blower 13 described in the first embodiment is omitted and the blower tube 11 is placed closer to the urine surface.

In this structure, the human waste which has been sufficiently pre-decomposed in the stirring tank 1 flows into the processing tank 9, and the human waste in the processing tank 9 is stirred and oxygen is supplied by the air supply from the second blower 16. It is supplied and decomposed by the activity and chemical reaction of aerobic bacteria.

Further, the pre-decomposed human waste is the water level detection unit 1
When the storage lower limit position of 9 is reached, the exhaust fan 21 is controlled so that a large amount of gas such as carbon dioxide generated in the processing tank 9 and floating on the liquid surface of the urine is discharged from the second exhaust port 18 together with the steam. It is forcibly exhausted by 21, and with the exhaust,
By synergistic action with the air that has flowed into the treatment tank 9 from the blower cylinder 11, the bubbles covering the urine surface generated by the supply of air from the second supply pipe 14 are scattered, resulting in an oxygen deficiency state. It prevents the aerobic bacteria from dying, and supplies a large amount of oxygen from the surface of the urine to further activate the aerobic bacteria's activities and chemical reactions,
Further enhances the decomposition of human waste.
