  • 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.

  • Patent number: 7173201
    Abstract: A remote controller 1 is capable of achieving switching operation even when the user presses substantially any place of a switch. A toilet seat open/close switch 12 has a tiltable member 20 which is tiltably supported at its front lower portion to an upper portion of a main body 2, a switch body 30 which is pressed by the tiltable member 20 when the tiltable member 20 tilts, and a cap 40 which is mounted to the upper portion of the main body 2 such that the cap 40 can be freely displaced in the anteroposterior direction and the vertical direction. The tiltable member 20 is disposed in a cavity 41 formed inside the cap 40. As the cap 40 is pressed from front or from above, the tiltable member 20 is pressed by the cap 40 to tilt, whereby the switch body 30 conducts the switching action.

  • Patent number: 7165577
    Abstract: A cleaning valve drive unit constituted to be able to supply water to a toilet by manual rotational operation of a main shaft in which the main shaft is constituted to be able to pull out from a cleaning operation position to a draining operation position. Whereas an operation limiting mechanism with respect to the main shaft enables to carry out cleaning operation to the toilet by rotational operation around an axis line with respect to the main shaft when the main shaft is disposed at the cleaning operation position, when the main shaft is moved to the draining operation position, the operation limiting mechanism permits to drain water by the rotational operation around the axis line with respect to the main shaft.

  • Patent number: 7069604
    Abstract: The present invention provides an open/close valve which contributes the stabilization of the operation responsibility. A housing has a water-in port and a water-out port. Furthermore, a piston which is slidably mounted in the housing in an axial direction by means of an external operation of a shaft, and a pressure offset means for offsetting the pressure which the piston receives from water in the water-out port to the other side are provided. The piston is attached to a seat face of the housing by being slided on one side in an axial direction to close the communication between the water-in port and the water-out port, and the piston is detached to the seat face of the housing by being slided on the other side in an axial direction to open the communication between the water-in port and the water-out port. The pressure offset means comprises a pressure offset room which is formed at the other side of the piston, and a passage for communicating one side of the piston with the pressure offset room.
