  • Publication number: 20090288245
    Abstract: In a drain socket for a toilet stool which comprises a vertical pipe having an upper end connected with the discharge port of the toilet stool, an adjustable pipe extending substantially horizontally from the lower end of the vertical pipe and a connecting pipe between the adjustable pipe and a drain in the floor of a toilet, the vertical pipe has a bend causing it to have at its lower end an axis displaced longitudinally and rearward of the toilet stool from its axis at its upper end to thereby define an eccentrically curved flow path. The socket adapts a toilet stool for installation in a wide range of drain positions and produces a siphoning action rapidly to flush the toilet bowl effectively with a small amount of water.

  • Patent number: 7594282
    Abstract: A pipe work 10 provided with a cleaning control valve V1 is connected to a rim 3 of a toilet main body 1 in a hygienic western-style toilet facility provided with an ejector inhaling and discharging air from a water-discharge channel where there is no possibility for odors and filthy water to be supplied to a toilet bowl in cleaning operation. A branch pipe 11 is branched from more upstream side than the cleaning control valve V1 of the water-supply pipe 10, and is connected to the ejector 20 through a U-shaped pipe 12 and an ejector water-supply valve V2. 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.

  • Publication number: 20090151063
    Abstract: A toilet flushing apparatus for firmly discharging a filth by a small amount of flush water and by a short period of time and still having a flush sound. The toilet flushing apparatus includes a first water supply supplying flush water to a toilet bowl of a toilet main body, a second water supply additionally supplying the flush water, a drain flow path communicated with a downstream side of a water seal portion of the toilet main body, an air sucking mechanism sucking air from the drain flow path, and a control apparatus controlling the first and second water supplies and the air sucking mechanism. The control apparatus produces a siphon operation by operating the air sucking mechanism continuous to operate the first water supply and to open an opening/closing valve through which flush water from the second water supply enters the toilet bowl, after forming a swirl flow inside the toilet bowl and before finishing the siphon operation.

  • Publication number: 20090146090
    Abstract: A pilot-type water discharging/stopping and flow regulating valve device capable of performing both the discharging/stopping of water and the regulation of flow by light operations, and capable of, once the flow is regulated, discharging the water at a pre-regulated specified flow in the next water discharge even if the water is stopped. The pilot type water discharging/stopping and flow regulating valve device has a main valve, a back pressure chamber, an introducing small hole, a pilot channel and a flow regulating mechanism. The flow of the main channel is regulated by advancing and retreating the main valve following the advance/retreat of a pilot valve. The valve device further has a water discharging/stopping switching mechanism that switches between the discharging and stopping of water by advancing and retreating the pilot valve between a water discharge position and a water stop position.
