| 20080244819 | SELF-PLUNGING TOILET AND METHOD OF CLEARING A TOILET - The present toilet relates to devices for removing clogs from drains and hand operated toilet plungers. More particularly the present invention concerns a toilet which when clogged can clear the clog automatically. With one push of a valve or turning a valve, clogs are moved and eliminated. The toilet contains within the toilet base a plunger or means to clear the obstructions. | 10-09-2008 |
| 20100229295 | DRAIN HOSE AND TOILET SYSTEM USING THE SAME - A water control tubular portion is fixed to the forward end of a discharge hose body. The water control tubular portion is a tubular body or an inverted funnel-like (trumpet-like) tubular body and has water control sections inside it. The water control sections are arranged zigzag so that the amount of discharge of an object (e.g. sewage) becomes as constant as possible and the speed of the discharge can be made slackened. Since the amount of discharge of the object from the forward end of the discharge hose body becomes substantially constant by the water control tubular section and the speed (flow speed) of the discharge is slackened, the forward end of the discharge hose is not fluttered by the pressure of a fluid object (sewage) sent under pressure from a simple toilet device. | 09-16-2010 |

| 20110094024 | SEALING MEMBER FOR A FLUSH TOILET - A flush toilet includes a base and a bowl assembly defining a bowl. The bowl assembly is mounted to the base and defines a discharge opening at a lower end of the bowl. A waste ball valve assembly is mounted to the flush toilet for selectively opening and closing the discharge opening of the bowl assembly. A common sealing member operates to seal the bowl to the base and to wipe a ball of the waste ball valve assembly as the waste ball valve assembly is selectively opened and closed. The common sealing member has a generally horizontal portion for wiping the ball of the ball valve assembly and a compressible cylindrical portion upwardly extending from the generally horizontal portion. The cylindrical portion is compressed between the base and the bowl to define a seal therebetween. | 04-28-2011 |
| 20110113542 | TOILET FLUSHING ASSEMBLY AND SEQUENCE - A toilet has an electronic flush assembly operable in either a short or long flush sequence selectable by a user. The long flush sequence includes a pre-rinse cycle and a rinse cycle in which the a supply valve and a flush valve are both opened and closed twice, once each first during the pre-rinse cycle and again during a subsequent rinse cycle. The rim supply valve and the flush valve are opened during the pre-rinse and rinse cycles but are closed at the start and end of each cycle. An electronic control controls operation of the valves as well as water supply control components. Level sensors can also be included to provide feedback to the controller, for example, to prevent overflow conditions. | 05-19-2011 |

The motor of the valve actuator may be positioned between the bowl of the fixture and a leg of a trapway to provide compact assembly. A belt drive laterally extending along the trapway links the motor to the flush valve. The method of calibrating includes establishing stop points which are at positions of less resistance than hard stop positions. | 01-23-2014 |
| 20160040417 | DISCHARGE VALVE APPARATUS AND ONE-PIECE FLUSH TOILET INCLUDING SAME - A discharge valve apparatus of the present invention includes: a discharge portion main body member attached to discharge opening, forming the inside of discharge flow path for guiding flush water from an inflow opening formed at one end thereof to an outflow opening formed at the other end thereof; a valve body for opening and closing the inflow opening of the discharge portion main body member; and an affixing portion, formed to project into the discharge flow path of a discharge portion main body member, for affixing the discharge portion main body member to a reservoir tank; wherein the inside surface of side wall portion in the discharge portion main body member at the same height as this affixing portion forms a curved portion, which curves outward so as to expand the cross-sectional area of the flow path. | 02-11-2016 |

| 20090188032 | TILTING-BOWL TOILET - Tilting Bowl Toilet comprises a frame, a toilet basin, and a tilting bowl. The tilting bowl is supported below the toilet basin to receive and hold water/waste delivered from the toilet basin. The tilting bowl tilts to discharge its content to drainage. The tilting bowl at standby is sustained to stay in a horizontal position by a sustaining turning moment about its support axis. When water is added, the turning moment produced by the tilting bowl with its content becomes larger than the sustaining turning moment, and the tilting bowl moves to a tilted position to discharge its content. As the tilting bowl tilts, the sustaining turning moment is simultaneously reduced to accelerate bowl tilting for efficient discharge of waste to sewage. | 07-30-2009 |
| 20090320200 | Kinetic Trapway - The present invention provides toilets having an outlet trapway that is movable during a flushing cycle. A toilet bowl has an opening adjacent its lower end. A conduit links to the opening so as to be able to swivel between a first upwardly directed position which forms a trap for the toilet, and a second less upwardly directed position which can be reached during the flushing cycle to facilitate evacuation of the toilet bowl. An actuator moves the conduit between the first and second positions during the flushing cycle in response to a condition of a water supply for the toilet, preferably without using electrical power to achieve this trapway movement. | 12-31-2009 |
| 20160377185 | MIXED MEDIA ORBITAL VALVE - Embodiments of the invention described herein thus provide improved flush valves that are designed with improved venting features and improved inlet designs.
