Feces odor eliminator

Abstract

I have designed a thermostatically controlled passive solar heater that blows by solar powered fan using very low wattage, warm air over a feces pile in an Improved Ventilated Privy (outhouse) for the purpose to dry or break the wet film over the feces pile rendering it odorless. I call it the Feces Odor Eliminator.

Claims

1. A Feces Odor Eliminator for retrofitting on an outhouse, the Feces Odor Eliminator comprising; a passive solar heat collector made from painted flat black aluminum tubes positioned behind polycarbonate glass, encapsulated on three sides and a top in a wooden box; A thermostat controlled circulating fan powered by a photovoltaic panel, the thermostat controlled circulating fan drawing air from a bottom of one or more heat collector tubes up through said tubes and directing hot air down through one said tube across a feces pile, on a continuous closed loop system; The feces odor eliminator configured for retrofitting on a south side of the outhouse.

Description

DETAILED DESCRIPTION

Feces Odor Eliminator

(1) The Feces Odor Eliminator invention is original. It is a passive solar heat collector made to operate inside of an Improved Ventilated Privy (outhouse). The purpose of the invention is to blow warm air across the feces pile in the holding tank below on a closed loop. The air is circulated by a small low power fan. The device is thermostatically controlled coming on at x+ and turning off at x (it could vary for different climates). There is also an on/off switch for added control of device which has no part of this application for patent. This switch is mainly to conserve solar electricity if need be. The device is currently made of three 2.53 aluminum gutter pipe painted flat black and mounted side by side. Two of the pipes are 3 feet long (intake), the other is 4 long (exhaust). At the base of this 4 pipe which comes nearly to the bottom of the shed/privy and slightly above the holding tank which extends approximately 27 below that, is the low powered fan.

Mounting

(2) On the back side (out side and pointing south) (see FIG. 1) of privy (outhouse) a hole through the wall is cut approx. 1330 where the pipes are exposed to the sun. The pipes are covered with Lexan Polycarbonate clear material. This polycarbonate helps radiate the sun and makes the unit look better. This part may change upon finding better material or application. The invention once again is to collect passive solar heat and blow it across the feces pile in order to break the wet film on the feces and thus eliminate the odor. I am not inventing a new or better way to collect passive solar heat. I am however inventing a specific way to use the heat collected for a specific purpose which is to be used to break the wet film on a feces pile in an Improved Ventilated Privy (outhouse) in order to reduce or eliminate the odor.

(3) The pipes are housed (enclosed) from the inside of the privy in a wooden box on the back side of shed or south side that measures aprox. 1330. The power supply is currently 12 volt solar but may operate on AC power. From the bench in the privy (see FIG. 2) where the toilet seat is mounted, the heat pipes extend down under the top of this bench. The bulk of the pipes are covered by the wooden box which is exposed on the back wall. My privy's use existing urine separation from the feces pile that effectively eliminates most odor, maybe 80%. My passive solar heaters' purpose is to eliminate all or nearly all of the remaining odor found on the feces by breaking the wet film on the surface of the feces. The size of this device and the materials used may vary, but the purpose, function, and operation will not. FIG. 1 and FIG. 2 are pictures showing outhouse not mounted on tank. See FIG. 2 to get idea of tank under outhouse. See brochure.
