Definitions

  • the present invention belongs to the toilet sector.
  • the purpose is the simultaneous elimination of faecal gases during defecation, with two clear objects: complete effectiveness and water saving.
  • the 1775 Alexander Cumming patented a horizontal S-shaped pipe, which, interposed in a downward hydraulic flow, seals the pipes preventing the return of potential underlying gases. If we break down the S into two 180° elbows or bends each ( Fig. 1 ), we get a first 180° vertical U-shaped elbow and a second inverted U-shaped one. Linking both elbows makes up the 360° of the siphon.
  • a liquid (water) flowing from left to right would be retained in the first elbow forming a water trap, the level of which would be determined by the height of the second elbow.
  • the water level remains stable because its excess spills into the second elbow.
  • the water trap level seals the first elbow preventing the back-flow of the underlying gases.
  • Cumming's design has another advantage. If the water flow is sufficiently intense, a plunger is formed in the downward branch of the second elbow which, attracted by gravity, generates a retrograde or siphon suction effect that in turn drags the contents of the first elbow, being able to empty the entire system.
  • Alexander Cumming's device placed in a toilet ( Fig. 1 ) and connected to the discharge (7) prevents the back-flow of the gases from the sewer through the seal of the water trap and further drags the solid and liquid stools into the discharge (7).
  • the water discharge flushes the double U system by the aforementioned siphon effect, leaving a water trap level that acts as a hydraulic check valve for the underlying gases.
  • the double U-shaped design provides two qualities: 1.- Back-flow preventer seal for sewage gases: and 2.- Depletion of the system contents when this is filled with a sufficient amount of water. This latter effect is based on “gravity” and the “cohesive force" of the liquids.
  • the siphon has two parts.
  • the first 270° form a single part (2) with the front receptacle or pan (6),
  • toilet bowl (2) usually made of ceramic, another one involving the remaining 90° (3) must be added.
  • This is a free, usually synthetic, part that serves as an adjustment and junction between the toilet bowl and the discharge (7), sealing the siphon.
  • An ordinary toilet ortoilet bowl (2) ( Fig. 1 ) consists of: 1.- A concave front container or pan (6) to receive the detritus, with its swing-out seat with its lid; 2.- A horizontal double U-shaped siphon of two differing branches: the 270° water trap and the 90° rod-shaped rear sleeve (3); and 3.- A water source, for example a tank or cistern (1), which releases the necessary amount of liquid to activate the system.
  • the tank is connected to the main network through a float valve or gauger (4), and to the pan (6) through a conical discharge valve (5).
  • the toilet must meet four requirements:
  • a common toilet ( Fig. 1 ) consists of:
  • Faecal gases are a mixture of: a/ ingested air: mainly oxygen and nitrogen; b/ a small amount of flammable gases that result from organic fermentation such as methane and hydrogen; c/ a heterogeneous group of gases that provide their characteristic odour such as hydrogen sulphide, indole, eschatol and carbonyl and butyric acids.
  • a conventional toilet ( Fig. 1 ) is a device or toilet bowl (2) in which the liquid and solid detritus deposited in a concave receptacle or pan (6) is sent to the discharge (7) through a double U siphon pipe.
  • a seat with its lid and a water tank (1) that activates the system Water passes from the tank (1) to the pan (6), from here to the siphon, and from the siphon with its rear connection sleeve (3) to the discharge (7).
  • the object of the invention is the simultaneous elimination of faecal gases along with the stools.
  • the gases must be captured at their source, that is, in the pan (6) or concavity of the toilet bowl. From here they must be guided to the discharge (7) without altering the siphon mechanism. To achieve this, gas and water must follow different pathways. This preserves the cohesiveness of the column of the liquid, allowing the adequate suction effect of the siphon.
  • the double siphon trap model ( Fig. 3 ) achieves the elimination of gases to the discharge by duplicating Alexander Cumming's design in the first elbow of the siphon. Here the second elbow and the connecting sleeve are preserved.
  • the water level of the trap acts as a permanent check valve for both the pan (6) and the accessory gas pipe (14).
  • pan (6) and accessory gas pipe (14) start at the upper part of the toilet bowl. All the contents are directed to the upward branch of the first U, remaining below the level of the water trap. The gases released here rise towards the second U and from here to the discharge (7).
  • the computer has sensors that indicate the time point of discharge. A suitable point for them is the gauger ( Fig. 1 (4)).
  • the check valves (18) are only supplementary. We have not found a background art for this double siphon trap. 2.- Behind ( Fig. 2 ), the two-way rear sleeve (20) links to a conventional power group (8) that sucks in and expels the gases from the fixed part of the seat, where the activation button can be placed.
  • the new double rear connection sleeve (20) sends the gases to the discharge (7) without mixing them with the water.
  • the gases suctioned from behind and below the seat are sent by an external hose (9) to the secondary or smaller mouth (11) of the double sleeve (20) and will reach the discharge (7) outside of the waterway.
  • the double span of the rear connection sleeve (20) is the distinctive character with respect to any other prior model.
  • the new sleeve maintains the 90° that complete the 360 of the siphon, as well as the traditional connections: a front one (12) that joins it to the toilet bowl and through which water and detritus circulate, and another rear one by which it joins the discharge (13).
  • This pathway preserves the function of the siphon as in any other classic model.
  • the sleeve has another secondary pathway eccentric or concentric with the main one, which is connected to the external hose (9) and which brings the gases from the pan through a new auxiliary connection (11).
  • the rear connection (13) is common for solids, liquids and gases. The main pathway for liquids and solids thus maintains sufficient length so that the necessary cohesive column of water that dredges the system is formed. The gases will be evacuated beyond this critical point.
  • the common connection (13) adapts the sleeve to any discharge.
  • the double rear connection sleeve (20) has a single connection to join to the discharge (13), but two independent ones in front; one for standard-sized liquids and detritus (12) and another smaller or secondary one for gases (11). It is in the latter where a one-way check valve (18) is also located or in its absence a plug.
  • This new sleeve can thereby be used in a conventional toilet.
  • the plug is essential, thus leaving the secondary gas pipe out of service.
  • the sleeve can be adapted to any extractor group, incorporating the check valve (18).
  • the placement of the power group (8) at the rear part of the seat seems, if not essential, at least most convenient.
  • This third model is thus composed of a secondary route in the toilet bowl (15) and another one in the rear connection sleeve (20).
  • This continuous two-way toilet configures a double pathway that runs along the entire route, from the upper edge of the toilet bowl to the discharge.
  • the splitting of the pathway can be in the toilet bowl ( Fig. 3 ), in the rear connection sleeve ( Fig. 2 ) with the discharge or in both ( Fig. 4 ).
  • the splitting in the rear connection sleeve ( Fig. 2 ) is a double eccentric or concentric rod-shaped parallel pipe (20): 90° elbow followed by a downward branch that connects to the discharge (7).
  • This new rear sleeve (20) has a double front connection to join to the siphon (12) and the pipe that provides the gases (11), and a single rear connection (13) that connects to the discharge (7).
  • the main pathway that leads to solid and liquid detritus is similar to that of any other conventional sleeve, with a length in the descending branch capable of housing a cohesive and efficient column of water that generates the suction necessary to empty the system.
  • the secondary pathway for the gases, eccentric or concentric, is parallel and independent with respect to the main one and releases the gas once it has passed beyond the latter.
  • the sleeve has in front a standard connection for the toilet bowl siphon (12) and another smaller one for the gas pipe (11). In the latter there is a one-way check valve (18) or in its absence a plug.
  • Both pathways have a single and common connection (13) with the discharge (7).
  • the splitting in the toilet bowl ( Fig. 3 ) consists of a secondary pipe (14) and parallel to the main one that make up pan and siphon.
  • This secondary pipe for gases opens, like the pan, in the upper part of the toilet bowl and ends in the upward branch of the first U of the siphon, below the level of the water trap.
  • the rest of the siphon and the rear connection sleeve are conventional.
  • a micro-computer (17) briefly interrupts the flow of gases during the discharge to avoid mixing gases and liquids. This brief suspension in the suction is compensated by the own flushing of the siphon. When the water level reaches the minimum the suction system is reactivated.
  • the programmer needs sensors that tell it the point which the discharge is at.
  • the tank gauger (4) can house one of these sensors.
