Abstract: The present utility model relates to the field of manufacture of sanitary wares, and provides a toilet. The toilet includes a seat body with a sewage accommodating bowl, and a cistern.

Abstract: A flush toilet having a toilet main unit cleaned by flush water is disclosed. The flush toilet comprises a reservoir tank for storing therein flush water; a bowl portion having a waste-receiving surface and a rim section; a drainage passage for expelling waste therethrough by means of siphon action; a rim water spouting port provided in the rim section at a position corresponding to a lateral region of the bowl portion; a jet water spouting port for spouting flush water toward an inlet of the drainage passage; a rim water guide passage for guiding flush water to the rim water spouting port; a jet water guide passage for guiding flush water to the jet water spouting port; and a flow dividing chamber for dividing and distributing flush water to the rim water guide passage and the jet water guide passage, wherein the flow dividing chamber, the rim water guide passage and the rim water spouting port are formed approximately along the same straight line.

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.

Abstract: A universal replacement toilet tank (10) that incorporates within a toilet tank (12) a piston flush valve (40) that functions in combination with a ballcock (22), a water closet (30) and a pressure increasing riser (120). The valve (40) is designed to be easily adjusted to allow a selected volume of flush water to flow from the toilet tank (12) into the water closet (30). The pressure increasing riser (120) consists of a hollow pipe (122) and a decorative sleeve (140) that are positioned between the toilet tank (12) and the water closet (30). The riser allows the toilet tank (12) to be elevated above the water closet (30) to provide an increase in the pressure of the water that is used to flush the water closet (30). The invention also includes a threaded adapter (100) having upward internal threads (102) and downward external threads (104).

Abstract: A dual power-flush toilet (20) which has a water closet (22), a water tank (24), a ball cock (26), and a first lever arm (28). A dual acting flush valve (30) is disposed within the tank and modified to incorporate an overflow opening (44), a refill elbow (46) and a beveled washer (32). A second tank lever arm (50) is installed into the tank and lifts the flush valves vertical tube (36) causing a partial flush of the water in the tank. The first tank lever arm is attached to the flush valves float assist arm (38) beneath the second lever arm lifting both the vertical tube and float assist (40) delaying the opening until a complete flush of the water from the tank is achieved. A pressure increasing riser (56) is added between the water closet and the water tank to boost the water pressure and more efficiently flush water from the tank into the water closet.

Abstract: A water closet including a body portion with an upper level and a lower level, and integral with the body portion, a closet bowl and an outlet conduit forming an odor seal at the bottom of the bowl. The odor seal has an outlet crest determining its highest water level. There is a flush water container adjacent to the body portion and means for flushing the closet bowl with water passing by gravity from the flush water container through the bowl and the outlet conduit. Further, the odor seal outlet crest is at a height level of at least 50 percent of the height of the upper level of the body portion measured from the lower level thereof, and close to the upper level there is an annular flush duct of substantially bottomless configuration opening into the bowl at a level above the odor seal outlet crest, and, in addition, the outlet conduit has a constriction at its outlet end.
