Patent number: 7165577Abstract: 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.Type: GrantFiled: December 4, 2003Date of Patent: January 23, 2007Assignee: Nidec Sankyo Corporation & Inax CorporationInventors: Hiroyuki Iwashita, Tsuyoshi Nakasone, Katsunori Tomita, Takanori Idota, Hironao Inoue

Patent number: 7036159Abstract: 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.Type: GrantFiled: October 7, 2003Date of Patent: May 2, 2006Assignee: Inax CorporationInventors: Katsunori Tomita, Yasuhiro Shirai, Koji Miwa, Kenichi Ito, Takanori Idota, Masataka Mizutani, Toshiaki Matushita

Patent number: 6895607Abstract: 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.Type: GrantFiled: May 18, 2001Date of Patent: May 24, 2005Assignee: Inax CorporationInventors: Takanori Idota, Junjiro Ebitani, Toshio Hino, Toshiaki Matushita, Katsunori Tomita, Takashi Minami, Masahiro Iguchi
