Embodiment

Referring to figs. 1 to Fig. 4, provide a kind of waste disposal unit 10 according to a preferred embodiment of the present invention, for receive human waste, separate solid and liquid waste, drying solid waste material and the solid waste of liquid and drying is separately stored.

As shown in Figure 2, waste disposal unit 10 comprises housing 12, dish 14 and scraper plate 16.

Housing 12 comprises in container 12a and envelope lid 12b. Container 12a comprises the right circular cylinder body portion with substrate, and the envelope lid 12b of circle adapts to the opening end of container 12a and the opening end of closed container 12a. Envelope lid 12b limits inlet hole 18, for being received in housing 12 by waste material.

The shape of dish 14 is circular, and the material low by frictional coefficient is made, and limits hole 20 at its center, and hole 20 is used as the outlet for the liquid waste flowed out from dish 14. It is clear that dish 14 is conical from Fig. 6, tilt downwards from its periphery to center.

Scraper plate 16 is made up of the rectangular sheet of the low-friction coefficient material being formed as spiral, and this spiral is for every 360 degree of rotations, and radius increases between 10 centimetres to 30 centimetres, it is preferable to increase by 20 centimetres.

Dish 14 and scraper plate 16 are all positioned at housing 12. But, dish 14 is to rotate in housing 12, and scraper plate 16 is fixed with housing 12 to prevent relative rotating. Scraper plate 16 is supported on dish 14. Or, scraper plate 16 can above dish 14 between separate and be no more than 5 millimeters.

Actuating device is rotating disk 14 in housing 12. Actuating device comprises ratchet (ratchet), and ratchet is included in corresponding tooth 24 downside of the foot-driven lever 22 and dish 14 extended near inlet hole 18 from housing. The increment rotation that each circulation of foot-driven lever 22 can cause dish 14 between 10 degree to 35 degree, be preferably 22.5 degree.

With reference to Fig. 5, liquid saves the center that device 24 is positioned at dish 14, below center hole 20/ liquid exit. And the peripheral region that device 26 is positioned at dish 14 saved by solid, by the terminal of scraper plate 16.

Referring back to Fig. 1 to Fig. 4, toilet seat assembly is positioned on housing 12, forms the framework of inlet hole 18, and the centre of form of inlet hole 18 is between radially inside 25 centimetres to 45 centimetres of the periphery from dish 14, it is preferable to 35 centimeters.

Add heating unit, with the temperature improved in housing 12, and accelerate the drying to solid waste on dish 14. The inner side of housing 12 is preferably heated to more than 60 degrees Celsius. With reference to Fig. 1, heating unit comprises the translucent top cap 30 covering the hole limited by housing envelope lid 12b. Top cover 30 allows solar radiation to enter and the inside of heated shell 12.

Diametrically relative with inlet hole 18 ventilation plant 32 is conducive to air via inlet hole 18, the motion that discharges by housing 12 and through venting port 32. The main purpose of such circulation suppresses vitiated air to overflow from housing via inlet hole 18. But, it also contributes to the drying to the solid waste left on dish 14.

We introduce the waste disposal unit 10 in work turning now to Fig. 5. User is sitting on toilet seat 28 and urine and ight soil is stored on dish 14 by inlet hole 18. Urine downwards towards the center flow of conical disks 14, flows to liquid by center hole 20 and saves in device 24 under gravity. But, ight soil remains on dish 14 due to the friction between ight soil and dish 14 and/or the obstruction that provides by scraper plate 16. , it may also be useful to person pushes away foot-driven lever 22 downwards and dish 14 is rotated 22.5 degree, then this rotation is enough to ight soil moves out of direct visual field when next user stand on above inlet hole 18. The air circulation realized by ventilation plant 32 prevents unpleasant smell from being overflowed by inlet hole 18, and heating unit 30 accelerates the drying of ight soil. Follow-up each actuating of foot-driven lever 22 all makes dish 14 rotate relative to static helical flight 16 increment, and wherein ight soil leans on scraper plate 16 and pushed to the periphery of dish 14 by scraper plate. Due to the diameter that scraper plate 16 rotates the radius increased reflect inlet hole 18 for every 360 degree, so when dish 14 has completed 360 degree of rotations, new user can not see the ight soil previously deposited by inlet hole 18. The continuation of dish 14 rotates and just ight soil is moved towards the periphery of dish 14 further, enters into solid save device 26 until now dry ight soil is pushed away lower wall 14 by scraper plate 16.

Liquid and solid are saved device 24 and 26 and frequently are cleared.

It is to be understood that

(i) dish 14 can comprise passage or ridge (not shown), to be conducive to guiding urine towards center hole 20.

() replaces comprising single helical flight 16, and waste disposal unit 10 can comprise multiple scraper plate, and they separate and orientation along between the concentric virtual spiral of the dish 14 of circle. The same with helical flight 16, the radius of virtual spiral increases between 10 centimetres to 30 centimetres for each complete rotation, it is preferable to increase by 20 centimetres. In such enforcement mode, ight soil can not lean on scraper plate lastingly, but by rotation until ight soil leans on this series of scraper plate on dish, and by its along dish diametrically outwards increment mobile.

() helical flight or virtual spiral can along its radius " tightening up ", that is, spiral can reduce to the radial delta of inner rotary for each.

(iv) the liquid waste flowed down from dish can also be discharged into covered conduit (Frenchdrain) via liquid exit, does not just need liquid to save device in such setting.

(v) foot-driven lever 22 can replace with by the bar of manual manipulation.

(vi) waste disposal unit can be comprised skewed slot (chute) and guided towards the center of dish 14 further by the waste material deposited by inlet hole 18.

(vii) any point place that ventilation plant 32 can be positioned on housing, it will be preferred that near its periphery.
