Tankless toilet, western-style flush toilet, part washing device and spud for flush toilet
View Patent ↗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.
