To provide a urinal apparatus, including: a water supplying device configured to supply water to a bowl section of a urinal; a trap section provided in a lower part of the bowl section and configured so that urine and water flow into the trap section; and a water sprinkling device configured to sprinkle water droplets to a region inside the bowl section, the region being located between the trap section and position of a nose of a user facing the bowl section, wherein the timing of sprinkling the water droplets by the water sprinkling device being different from timing of supplying water by the water supplying device.

Urinal with separate water supplying and water spraying devices

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.

Urinal having continuously curved bowl surface

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.

Urinal

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 M; a first equipment flushing mode Min which a portion of flush water flushes the upstream side of a connecting portion; and a second equipment flushing mode Min which a portion of flush water flushes the upstream side of the connecting portion. At least one of either the first mode Mor the second mode M, 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.

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 sensoris amplified by an amp, and a frequency spectrum is determined by an FFT calculation portion. A flow rate is determined by conversion in a flow rate calculation portionon the basis of the frequency spectrum. A controlleroperates other devices on the basis of the flow rate calculated by the flow rate calculation portionand the operational state of a cleaning instruction button. Cleaning water supply valveis opened and closed in accordance with instructions from the controller. Electrolyzed water is generated in an electrolyzed water generating portionto prevent the formation of urinary calculus in a drainpipe, and this electrolyzed water is discharged from a water spout when an electrolyzed water supply valveis opened.
