Patent number: 9988803Abstract: A urinal having the bowl surface formed by only the front face portion in an upper region which does not have any forwardly projecting plate-like side walls at opposite sides thereof as in the conventional urinal. Flush water cleans a wider part of the bowl surface than in the prior art as well as reduce an area of the bowl surface that is not cleaned and provide an improved cleanliness and sanitation of the bowl surface. The urinal includes: a bowl surface being arranged so as to situate between a line segment connecting the left and right side edges and an arcuate segment of a circle having a diameter corresponding to the line segment, as viewed in the horizontal section through the flush water discharging device.Type: GrantFiled: March 13, 2015Date of Patent: June 5, 2018Assignee: TOTO LTD.Inventors: Minoru Tani, Yusuke Takiguchi, Yuichi Furuta, Tomohiro Kai, Hironori Yamasaki

Patent number: 9739043Abstract: A urinal for receiving and discharging urine having a bowl portion having a bowl surface for receiving urine; a spouting device disposed on a top portion of the bowl portion for spouting flush water onto the bowl surface; and a discharge trap portion, communicating with a discharge port disposed on a bottom portion of the bowl portion, for discharging flush water and forming a water seal on a downstream side of the bowl portion. The discharge trap includes a descending conduit, a horizontal conduit, and an ascending conduit, and a cross section perpendicular to a discharging direction of either the horizontal conduit or the ascending conduit on the discharge trap portion is formed so that an inner side of the urinal from a center of the cross section has a smaller cross sectional area than an outer side of the urinal from the center of the cross section.Type: GrantFiled: January 13, 2016Date of Patent: August 22, 2017Assignee: TOTO LTD.Inventors: Yoshifumi Seki, Satoshi Matsunaka, Yuichi Furuta, Hironori Yamasaki

Patent number: 9624657Abstract: A urinal capable of constraining the occurrence of uric scale in a discharge horizontal branch pipe even if flush water volume has been reduced by water conservation is disclosed. A urinal includes a control unit with a main flush mode M0; a first equipment flushing mode M1 in which a portion of flush water flushes the upstream side of a connecting portion; and a second equipment flushing mode M2 in which a portion of flush water flushes the upstream side of the connecting portion. At least one of either the first mode M1 or the second mode M2, the value of the discharge volume or the discharge instantaneous flow volume discharged is set to be equal to or greater than the value of the discharge volume or the discharge instantaneous flow volume in the main flush mode.Type: GrantFiled: August 28, 2015Date of Patent: April 18, 2017Assignee: TOTO LTD.Inventors: Satoshi Matsunaka, Yuichi Furuta, Hironori Yamasaki

Patent number: 6948194Abstract: An object of the present invention is to provide a toilet cleaning device which is capable of cleaning a toilet stool by supplying cleaning water in an appropriate quantity corresponding to the state of usage by a user, which is provided with a self-diagnosis function for diagnosing cleaning water stoppage or the like, and which has a simple constitution so that maintenance can be performed easily. The output of a Doppler sensor 11 is amplified by an amp 31, and a frequency spectrum is determined by an FFT calculation portion 32. A flow rate is determined by conversion in a flow rate calculation portion 33 on the basis of the frequency spectrum. A controller 34 operates other devices on the basis of the flow rate calculated by the flow rate calculation portion 33 and the operational state of a cleaning instruction button 16. Cleaning water supply valve 36 is opened and closed in accordance with instructions from the controller 34.Type: GrantFiled: August 13, 2002Date of Patent: September 27, 2005Assignee: Toto, Ltd.Inventors: Kentaro Todoroki, Kuniaki Shinohara, Toshio Koguro, Yuichi Furuta, Mie Ikushima
