  FIG. 1 is a schematic longitudinal sectional view of a simplified toilet 100 provided with a human waste treatment apparatus 10 as an embodiment of the present invention. In the simplified toilet 100, for example, an indoor compartment 101, a piping compartment 102, and a human waste treatment device installation compartment 103 are formed in a housing made of FRP or aluminum. On the inner wall 104 of the indoor compartment 101, a urinal 20 into which human waste is dropped is installed. The urinal 20 is connected to a connecting pipe 30 for dropping human waste dropped from the user P and introducing it into the urine processing apparatus 10. Further, an exhaust pipe 40 connected to the exhaust port 12 of the human waste treatment apparatus 10 and extending outdoors is housed in the piping section 102. The exhaust pipe 40 includes a ventilation fan (not shown) that rotates in response to the driving force of the motor, and can ventilate the human waste treatment apparatus 10.

  FIG. 2 is a perspective view for explaining the appearance of the human waste processing apparatus 10 according to the present invention. The human waste processing apparatus 10 includes, for example, a housing 10 ′ molded from stainless steel. The upper surface 10 a ′ of the housing is used to collect human waste dropped from the user P and introduce it into the urine processing apparatus 10. An opening 11 is formed. A connecting pipe 30 connected to the urinal 20 is connected to the opening 11.

As shown in FIG. 2, the human waste treatment apparatus 10 may include a control box 50 that controls the rotation of a ventilation fan (not shown) on the upper surface 10 a ′.

  FIG. 3 is a transparent view for explaining the internal structure of the human waste treatment apparatus 10. As shown in FIG. 3, a plurality of guide trays 200 are installed in the housing 10 ′ of the human waste treatment apparatus 10 so as to be staggered with a predetermined inclination with respect to the side surface 10b ′ or 10c ′. ing. A collection tray 201 for collecting the human waste guided by the guide tray 200 is installed at the lowermost part inside the housing 10 ′. The guide tray 200 and the collection tray 201 are, for example, box-shaped members whose one surface formed of stainless steel is open. The guide tray 200 and the collection tray 201 are filled with a filter medium F for promoting adsorption and evaporation of human waste. As the filter medium F, any porous material such as charcoal, bamboo charcoal-derived charcoal, other activated carbon, plastic, ceramics, etc. can be used. It is preferable to use bamboo charcoal having a size of 1 mm to 3 mm in consideration of the influence on the environment during processing.

  The guide tray 200 can be integrally formed with the side surface 10b ′ or 10c ′ of the housing. For example, the guide tray 200 is guided on the inner surfaces of both sides of the side surfaces 10d ′ and 10e ′. Of course, it is possible to provide an attaching / detaching means having a rail member for fixing. In this case, since the guide tray 200 is detachable from the housing 10 ', for example, the filter medium F that exceeds the use limit can be easily replaced.

  Next, the structure of the guide tray 200 will be described with reference to FIG. FIG. 4 is a plan view for explaining the structure of the guide tray 200. As shown in FIG. 4, the guide tray 200 has, for example, side walls 200b, 200b ′, 200c, and 200c having a height of 30 mm on both sides of a stainless steel plate 200a having a length in the longitudinal direction of 1,000 mm and a length in the short direction of 300 mm. It is a box-shaped member that is molded by standing up and has an open surface. Then, substantially L-shaped guide rails 210a or 210b are erected alternately with a predetermined interval and angle from the side wall 200b side to the side wall 200b ′ side and from the side wall 200b ′ side to the side wall 200b side.

  The number of guide trays 200 installed in the housing is not particularly limited. For example, when the amount of human waste is 200 to 250 mL, 15 charcoal or bamboo charcoal is used as the filter medium F. By using six guide trays 200 filled to a height of about 20 mm, approximately 12 L (2 L × 6 sheets) equivalent to about 50 times of urine can be processed in terms of the number of urine.

  In addition, the guide tray 200 may include a heating element such as a bar heater 212a having a lead wire 212b as shown in FIG. By setting it as such a form, evaporation of the urine adsorb | sucked to the filter medium F with the heat | fever supplied from the rod heater 212a can be accelerated | stimulated. In FIG. 5, a bar heater is shown as an example of the heating element. However, the heating element is not limited to this, and for example, a planar heating element having a self-temperature control function (PTC characteristic) may be used. This planar heating element having PTC characteristics is formed by subjecting a special semiconductor ink (PTC ink) in which an organic polymer semiconductor is adsorbed to a crystalline, thermoplastic resin derivative to a honeycomb roll coat together with a copper foil electrode of a heat resistant nonwoven fabric, It is a surface.

  Further, as another method for promoting the evaporation of urine adsorbed on the filter medium F, for example, as shown in FIG. 6, a blower fan 213 as a blowing means is provided on the side surfaces 10′d and 10′e of the housing, and the filter medium It does not matter as a form in which air is directly blown to F. With such a configuration, the outside air can be brought into direct contact with the filter medium F, and evaporation of urine adsorbed on the filter medium F can be further promoted.

  As described above, according to the human waste processing apparatus according to the present embodiment, it is possible to provide a human waste processing apparatus that does not require a large human waste tank or the like, is hygienic, and can process human waste at low cost. Can do.

  Note that a solar panel for solar power generation, a windmill for wind power generation, or the like may be attached to the upper wall of the ceiling (roof) portion of the simplified toilet 100 having the above configuration. Electric power obtained by solar power generation or wind power generation is stored in a storage battery (not shown) or the like and supplied to power for driving a ventilation fan, a rod heater 212a (not shown), or the like. Of course, as a power source for driving a ventilation fan, rod heater 212a, etc. (not shown), it is possible to use power supplied from a conventional simple generator, a household AC power source, or the like.

  Further, for example, as shown in FIG. 7, the human waste processing apparatus 10 according to the present invention can be used as a biotoilet 300 integrated with a toilet tank 70 provided with stirring means for stirring sawdust and manure. It is. In this case, since the amount of manure introduced into sawdust can be minimized, for example, even when a large number of users add only urine, the blending balance of manure and sawdust is not lost. It is possible to sufficiently promote the degradation treatment by bacteria.

  In the description of the present embodiment, the form in which urine is introduced into the human waste treatment apparatus 10 through the connecting pipe 30 connected to the urinal 20 has been described, but the present invention is not limited to this. Absent. In other words, for example, a partition member that separates urine and feces is provided in a toilet installed in a toilet tank 70 equipped with stirring means for stirring sawdust and feces and urine, and only sewage separated by the partition member is treated.
