  • Patent number: 5487193
    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.

  • Patent number: 5404597
    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.

  • Patent number: 5386596
    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.

  • Patent number: 4407025
    Abstract: A water-conserving toilet is disclosed and includes a bowl for receiving waste and a waste outlet extending laterally from the bowl and defining a first, shallow trap arranged so that a relatively shallow body of liquid is normally retained in the bottom of the bowl for preventing gaseous flow through the trap. A flush system is provided and is arranged, when operated, to deliver a charge of flushing liquid into the bowl in a direction to cause said body of liquid to be discharged through said outlet. An enlarged chamber communicates with said bowl outlet for receiving waste from the bowl. An outlet extends outwardly from the chamber and is adapted for connection to a sewer inlet. The chamber outlet defines a second trap of substantial height capable of preventing reverse flow of sewer gas into the chamber in use.

  • Patent number: 4197599
    Abstract: The present invention is related to a water-saving toilet bowl wherein the main flush inlet and secondary flush inlets are improved whereby the secondary flush enters into the upper reservoir later than the main flush; and in addition, the guiding plate between the upper reservoir and lower reservoir is prolonged to increase the acceleration of gravity; having the features that no more than six liters of water is required to flush away the defecation or the like.

  • Patent number: 4155129
    Abstract: A bottom discharge toilet in which a trap is formed integrally with the toilet base. While the trap plays no role in the flushing action of the toilet itself, it is adapted to receive the discharge from other plumbing fixtures and thereby to serve as a single, common trap for such fixtures. By directing the received discharge through the interior of the toilet, the trap also assists in keeping the toilet outlet line clear. To further reduce the overall cost, the toilet is formed in several interlocking pieces as a kit which can be conveniently shipped and handled, and then assembled on-site. A novel water inlet valve operates in cooperation with a flushing mechanism to clear the toilet and refill the bowl with a minimum of water consumption.

  • Patent number: 4115883
    Abstract: A toilet for conserving water, the toilet having a water storage chamber which includes an expandable diaphragm wall that on filling under household water supply pressure conforms to a wall of a complimentary air chamber separated from the storage compartment by the diaphragm. The chamber communicating with a gated discharge cavity between a trap and a sewage line, wherein water in the storage compartment is released at a high flow rate into a bowl having sedentary waste water, the waste water being exhausted from the bowl into the discharge cavity by a partial vacuum action generated by the contracting diaphragm concurrent with the introduction of the supply water, the waste water being gated from the discharge cavity into the sewer line on reduction of the vacuum pressure, whereby the supply water replaces rather than flushes the waste water.
