A flush toilet includes a toilet main body, a flush water tank device, and connection conduits for supplying, to a toilet main body, flush water supplied from a reservoir tank. The reservoir tank includes a large tank portion on a large volume side in the reservoir tank when the reservoir tank is divided into two at the left-right center and a small tank portion on a small volume side in the reservoir tank when the reservoir tank is divided into two at the left-right center. The upstream end of one connection conduit is connected to the large tank portion and, on the other hand, the downstream end of the other connection conduit is connected to the other side of the toilet main body divided into two at the left-right center.

Flush toilet

A flush toilet includes: a water supply channel that allows flush water to be supplied from a flush water storage tank to a rim spout port and a jet spout port; and a switching device that switches a water supply path so as to execute a first flushing process of spouting the flush water in the water supply channel from the rim spout port and after that, execute a second flushing process of spouting the flush water in the water supply channel from at least the jet spout port. The switching device includes a switching valve body that operates by receiving the water pressure of the flush water pressurized by a pressure pump. This switching valve body performs switching to a water supply path that allows the first flushing process or the second flushing process to be executed according to the water pressure generated by the pressure pump.

Problem: To provide a flush toilet wherein anomalous sounds can be suppressed from occurring when flush water is spouted from the rim spout port together with air accumulated in the upper portion within the rim conduit, and quietness can be improved. Solution: The flush toilet of the present invention includes: a bowl portionhaving a bowl-shaped waste receiving surfaceand a rim portionformed on a top edge of a waste receiving surface; a rim spout portconfigured to spout flush water from the rim portion onto the bowl portion; a rim conduitdisposed in the rim portion extending from a rear side region of the bowl portion to the rim spout port; and a stirring portionconfigured to agitate flush water which is supplied into the rim conduit

A urinal capable of suppressing the flow speed differential between the flow speed of flush water flowing into the front side of an ascending pipe and the flow speed of flush water flowing into the back side thereof, and of suppressing the occurrence of stagnation in the flow of flush water, and of suppressing the occurrence of uric scale. The urinal having a discharge trap including a horizontal pipe; a top portion of horizontal pipe is formed by a return flow path-forming portion at the bottom end of the shared wall; and a resistance portion for slowing the flow speed of flush water flowing in the vicinity of this bottom portion is formed at the bottom portion of the horizontal pipe.

Urinal

Disclosed is a flush toilet which comprises: a bowl portion having a waste-receiving surface and a rim provided along an upper edge of the waste-receiving surface; a drain trap conduit connected to the bowl portion to drain waste therethrough; a rim spout section including a rim spout port provided in a part of the rim located in a front region of the bowl portion for spouting the flush water, and a rim water-conducting passage provided to conduct flush water to the rim spout port; and a first water-conducting hose for supplying the flush water to the rim water-conducting passage located in the front region of the bowl portion, via beneath the waste-receiving surface, wherein the first water-conducting hose is configured to enable flush water to remain thereinside during stop of supply of the flush water.

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.

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.

A toilet device with a system for inspecting the health condition of the toilet user includes a toilet having a bowl surface with a urine reservoir for holding a urine sample, a box having at least a water tank disposed rearwardly and upwardly of the toilet, the box having an outlet opening in a bottom thereof, a slider for holding a urine test paper piece, the slider being movable from within the box toward the urine reservoir to immerse the urine test paper piece in the urine sample in the urine reservoir, a urine analyzing device disposed in the box, for analyzing constituents of the urine sample attached to the urine test paper piece, a lifting and lowering mechanism for reciprocally lifting and lowering the slider through the outlet opening along a substantially vertical inclined path between the urine analyzing device and the urine reservoir, and a display panel for controlling the lifting and lowering mechanism and the urine analyzing device and for displaying results of a urine analysis effected by the urine analyzing device.
