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.

Cleaning valve drive unit

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.

Tankless western-style flush toilet

The present invention provides a tankless toilet which can realize the reduction of the manufacturing cost without deteriorating the washing ability of water in the inside of a rim channel. The western-style toilet body includes the rim channel which is formed in the inside of a rim and is capable of washing a toilet bowl with water, and a rim water guide passage which is concealed in a rear wall face of the western-style toilet body and is connected to the rim channel from behind. Further, a through hole which is communicated with the rim water guide passage is formed in the rear wall face of the western-style toilet body. A spud is engaged in the inside of the through hole. The rim conduit is communicated with the rim channel by a water supply passage of the spud without passing the rim water guide passage, while an atmosphere communication hole of a water supply device is communicated with the rim water guide passage by means of a water discharge passage of the spud through a tube.

Tankless toilet, western-style flush toilet, part washing device and spud for flush toilet

The present invention provides a western-style flush toilet in which the performance of a component which constitutes a function device is not damaged, and simultaneously, the cleaning performance of a western-style toilet body can be surely improved. The western-style flush toilet includes a western-style toilet body, and a part washing device which is mounted at the rear portion of the western-style toilet body. The part washing device is capable of moving upward in such a manner that at least the rear of a bowl face of the western-style toilet body is exposed. A conceal member for concealing the component or the space which maybe possibly exposed when the part washing device moves upward is mounted.

Western-style water closet

A tankless western-style flush toilet having a western-style toilet body and a toilet washing device configured to wash the western-style toilet body with water, the toilet washing device including an open/close valve configured to be directly connected to a city water service pipe to supply water from outside and configured to spout water by being opened and closed electrically. The toilet washing device includes a control portion configured to ensure at least two periods of releasing times of the open/close valve, and a mechanism for switching the control portion in accordance with a pressure of city water in the city water service pipe.
