PROBLEM TO BE SOLVED: To contrive to shorten an excrement time, simplify this device and reduce the size of the device by providing a suction pipe on a jet pump which produces a negative pressure by spraying pressure water and sucking up the excrement of the cared or the like and discharging as a mixed air jet flow. SOLUTION: Water 14 in a water storage tank 5 is pressurized with a submerged pump 6 or the like and the pressurized water is sprayed into a suction chamber from a spray nozzle 7, thereby forming a jet pump MJP which produces a negative pressure. This jet pump MJP is used to suck up the excrement of the cared 4 on a bed 3 where the excrement is crushed and exposed to air by a mixed air jet flow, thereby discharging the excrement from a discharge outlet 12 to an onsite wastewater treatment equipment septic tank or a drain tank 13 and so forth. In the case where this jet pump MJP is set up on a car or the like, the water storage tank 15 is connected to the drain tank 13 where a deodorant or the like is added into the drain tank 13 and water is circulated and used. In this case, the exhaust gas of the car can be used to drive the pump. This construction makes it possible to discharge bodily wastes with higher efficiency and simplify the device and reduce the size of the device as well. |
