Abstract: A toilet that applies pressured air between an upper trap (30) that connects to the toilet bowl and a lower trap (32) that connects to a drain (16), includes a pressured air source (42) that holds a large volume of pressured air equal to at least 30% of the volume of the trapway passage (34) that connects the traps. The pressured air source includes a container (70) with its top coupled though a conduit (90) to the trapway passage, and with air in the container top compressed by water rising in the container after each flushing. The container top lies at least as high as the full water level (52) in the toilet tank when the toilet tank is full.

Abstract: A toilet has a source (42) that applies a vacuum to a trapway (14) at the beginning of a flushing to immediately flush the toilet bowl (12). As a result, water from the water tunnel 26 and the toilet bowl top channel 28 flow into the bowl after the flushing to create a large water spot (98) in the toilet bowl. A low water flush (e.g. 1½ liters to flush urine) can be obtained by not letting water flow out of a secondary volume (63) that lies outside a divider (140) in an isolator (40).

Abstract: A water closet has a variable siphon soil exhaust system with a flexible water bladder connected to a water inlet, a tension spring within the water bladder to contract the water bladder, a variable siphon tube connected to the water bladder to allow soil to be exhausted from the bowl while lifted and lowered by an expanding and contracting motion of the water bladder, and a small tube for connecting the water bladder to the variable siphon tube. A cover has a first port connected to the water supply passage, a second port connected to the bowl, and a third port connected to a bottom tube laid under the floor. The variable siphon tube has one end connected to the bowl through a bellows tube and an opposite freely movable open end communicating with the interior of the cover.

A discharge outlet of water of the ejector 20 is connected to a second water-discharge channel 7 through a pipe work 13. One end of a negative pressure transmission channel 21 is connected to an air suction inlet 20a provided at a throat portion of the ejector 20. The other end of the negative pressure transmission channel 21 is connected to an upper end 5a of a rising portion of a first water-discharge channel 5.

Abstract: A water saver toilet that produces a larger water spot (122) in the toilet bowl (12) and a better flushing, and that enables partial and full flushing. A trapway (14) that extends from the toilet bowl outlet to a drain (16), has upper and lower traps (30, 32) and a trapway passage (34) that extends between and into the traps. The lower trap is constructed to be sealed by water therein prior to each flushing, and a pressured air source (98) applies pressured air to the trapway prior to a flushing. The pressured air in the trapway pushes some upper trap water into the toilet bowl to increase the water spot therein. A first container (40) lies in the water tank, and the water therein can be flushed down from the first container though a coupling region (80) and though a flush valve (24), for a partial flushing. A full flushing is achieved by opening a second valve (62) to pass water lying in the tank around and above the first container, and through the coupling region and the flush valve.

Abstract: A toilet flushing method causes high-pressure flush water, provided by a flow pipe, to spray along the baffle in the bottom of the trap of a toilet bowl and causes the flush water used for washing the toilet bowl to spray into the toilet bowl. The high-pressure flush water discharges the egesta with water in order to supply sealing water to the trap. A toilet, which uses components for improving the prior art toilet, carries out the flushing method.

Abstract: A vacuum assist toilet provides an efficient flushing in a tank of relatively low height. A container assembly (36) includes a largely sealed container (34) that lies within the tank (12) to hold water that is dispensed in a flushing so as to create a vacuum at the top of the tank for application to the toilet bowl outlet. The flush valve (40) lies within the container, and the lower portion of the container is isolated from tank water surrounding the container, so water used during a flushing is obtained primarily by the outflow of water within the container and through a valve seat at the bottom of the container. A baffle (130) largely surrounds the region containing the flush valve, to produce an earlier dosing of the flush valve.

Abstract: The invention provides a toilet flushing system comprising a water reservoir provided with a water inlet, and a water outlet for directing water into or towards an associated toilet bowl; a discharge chamber communicating with the discharge outlet of the toilet bowl, the discharge chamber having at a downstream location thereof an exit opening provided with closure means; and air conduit extending between an upper end of the water reservoir and the discharge chamber such that reductions in air pressure within the upper end of the water reservoir caused by a fall in water level in the water reservoir are transmitted to the discharge chamber to produce temporarily a partial vacuum therein thereby to draw water from the toilet bowl through the discharge chamber.

Abstract: A tank type toilet has a water saving, vacuum-assisted flushing system that incorporates a diverter valve disposed in the tank portion of the toilet. During the flushing of the toilet, pressurized water is discharged from a ballcock valve assembly in the tank and delivered to the diverter valve which creates from the received water a water jet that is used to create a vacuum area within the diverter valve. The vacuum area is communicated with an uppermost interior portion of the bowl trapway to facilitate a main flushing action in the bowl that requires less flushing water. At the same time, the water jet entrains tank water therein, through water inlet openings in the diverter valve body, and delivers the jet and entrained water to the rim flushing passage of the bowl to augment the vacuum-assisted main flushing action.

Abstract: A water saver toilet is provided, of the type that applies a vacuum to the toilet bowl outlet to assist flushing, which effectively uses the vacuum and which can be of low height. The toilet bowl outlet includes upper and lower trap devices (44, 50 in FIG. 2) connected by a trapway (46), with a vacuum source applied to the trapway during a flushing to pull out water and debris from the toilet bowl. One vacuum source (FIG. 3) includes a largely horizontal diaphragm (76) which separates a water chamber (82) from a vacuum chamber (80). The water chamber is initially filled with water, which is rapidly emptied during flushing, causing the diaphragm to rapidly fall from an upwardly bowed configuration (76) to a downwardly bowed configuration (76A). The vertically moving diaphragm produces a vacuum in the vacuum chamber that is connected to the trapway.

Abstract: A vacuum assisted toilet is described, of the type wherein the toilet bowl outlet has a lower trap that is open to the passage of air therethrough except during each flushing when a vacuum is applied, which uses the vacuum more effectively. A vacuum source (46, FIG. 3) includes a first container portion (107) that holds water between flushings, with the water released during a flushing and creating a vacuum in a second portion (106) of the container that is coupled through a vacuum conduit (48) to the toilet bowl outlet. Instead of constantly coupling the second portion of the container to the bowl outlet, the second portion of the container is allowed to progressively expand but remain substantially unconnected to the bowl outlet until a predetermined amount of expansion (to 108) when the second portion is suddenly connected through the vacuum conduit (48) to the bowl outlet.

Abstract: A vacuum assisted toilet wherein a vacuum is applied between upper and lower traps (40,44 in FIG. 2) of a toilet bowl outlet during a flushing, wherein the lower trap is constructed to more reliably assure that an air passage (64) above a pool of water (52) of the lower trap will quickly close near the beginning of a flushing and will remain open between flushings. The lower trap has a lower wall (50) that holds a pool of water (52) with a pool top (62) of predetermined height (A) between flushings, and has an upper wall (60) spaced above the pool top to form an air passage. The upper wall forms a narrow but tall vent (100, FIG. 4) of the air passage, which assures that the air passage will always be open between flushings, and with the narrow but tall vent being quickly closed by water rapidly flowing therethrough at the beginning of a flushing.

Abstract: A water saver toilet is provided, of the type that applies a vacuum to the toilet bowl outlet to assist flushing, which effectively uses the vacuum. The toilet bowl outlet includes upper and lower trap devices (44, 50 in FIG. 2) connected by a trapway (46), with the lower trap device being initially unobstructed. At the beginning of flushing, the initial water flow causes obstruction of the lower trap device to air flow, and a vacuum is then applied to the trapway to pull out water and debris from the toilet bowl. One toilet (FIG. 5) is of the urinal type, and includes a container (214) lying within a water tank, with the lower end (218) of the container opening to the water tank, and with the upper end (219) of the container connected by a vertical vacuum pipe (221) to the trapway.

Abstract: A vacuum assisted toilet is described wherein a vacuum is applied to a toilet bowl outlet during flushing, which avoids malfunctions that could allow sewer gas to escape, and which uses flushing water effectively. The toilet bowl outlet includes upper and lower trap devices (40,44, FIG. 5) coupled by a trapway (42), with the lower trap device forming an unobstructed air passage when no water is moving therethrough but which includes a trapping region (64) that completely fills with water and forms an airflow barrier during flushing. The vacuum source includes a container (72, FIG. 1) in the toilet tank, with the container fixed in place in the tank to lie stationary therein, and with an ordinary flush valve (23) lying outside the container, so substantially the only part of the toilet that moves during flushing is the long developed and reliable flush valve.
