Abstract: An automatic water faucet includes a spout pipe; a spout port member having a spout port, the spout port member being housed at a leading end of the spout pipe such that the spout port member can be freely pulled out; and a sensor provided in the vicinity of the spout port for causing water to start being discharged upon detecting an object underneath the spout port. The spout port member is configured to be pulled out from a side behind the sensor in an axial direction of the spout pipe.

Abstract: A rotary handle is attached to a hot water single faucet and is a handle for controlling water discharge by rotational operation by an operator. A coefficient of friction of a grip member is set large in order to guide fingers of the operator to the grip member (operation surface) installed at a part of an outer surface of the rotary handle when the operator grasps the rotary handle. The grip member forms a line-shaped operation surface extending to a position not reaching a joint position of the rotary handle and the hot water single faucet along the outer surface in a direction of an axis of rotation.

Abstract: A detachment sensor detects attachment and detachment of a water discharger to and from a retainer. An object sensor detects presence of an object. A controller causes water discharge triggered by detection of an object by the object sensor while the water discharger is attached to the retainer and suppresses water discharge triggered by detection of an object by the object sensor while the water discharger is detached from the retainer. The controller suppresses water discharge triggered by detection of an object by the object sensor after attachment of the water discharger to the retainer until a non-detection state of an object by the object sensor continues for a predetermined period of time.

Abstract: A toilet flush tank is provided that is capable of preventing an increase in the external dimensions of a toilet main body even when the toilet flush tank is placed below the upper surface of a toilet main body and is also capable of performing toilet cleaning in a stable manner. A toilet flush tank stores cleaning water to be provided to a toilet main body having a toilet bowl and a toilet drainage channel that communicates with the downstream side of the toilet bowl. This toilet flush tank is placed inside a space below the toilet bowl and provided with a recessed portion that conforms to the shape of the toilet drainage channel at the upper surface of the toilet flush tank.

Abstract: A person-detecting sensor includes: a range-finding unit that decides whether a distance to a detection object falls within a predetermined detection distance range; a received-light quantity decision unit that decides whether a received-light quantity is equal to or greater than a predetermined received-light quantity threshold; and a continuation decision unit that decides whether a state of the detection object being present is ongoing. In the received-light quantity decision unit, after water discharge is started upon the detection determination unit determining a detection object to be under detection state, for a period during which the continuation decision unit decides the state in which the detection object being present is ongoing, the received-light quantity threshold is set to be lower than prior to when the water discharge is started.

Abstract: A person-detecting sensor includes: a range-finding unit that decides whether distance to a detection object falls within a predetermined detection distance range; and a specular reflection decision unit that decides whether reflected light is specularly-reflected light. The specular reflection decision unit performs a threshold determination regarding the count of pixels or the proportion of pixels exhibiting a received-light quantity of a predetermined proportion or greater with respect to the maximum received-light quantity among received-light quantities from the reflected light and decides that the reflected light is specularly-reflected light when the count of the pixels or the proportion of the pixels is a predetermined threshold or less.

Abstract: A water discharge device comprising a water discharge member formed with a slit-like discharge port and a discharge path, wherein the discharge path is formed with a reservoir chamber for holding, as reserve water, water flowing into the discharge path from its upstream side, and is formed with a constricting flow path that sends forth the reserve water in the reservoir chamber to the discharge port, and lateral surfaces on either side of the discharge path in its width direction are formed such that a path width of the discharge path spreads as approaching its discharge port side from its reservoir chamber side, and is formed such that the angle formed by an imaginary line paralleling the width direction of the discharge port and, on the lateral surfaces, a tangent line passing over the discharge port's opening rim is greater than or equal to 45° and less than 90°.

Abstract: An automatic water faucet includes: a water faucet; an imaging unit provided in a water discharge port of the water faucet and that images light reflected from a measure-distance target; a distance measurement unit that measures a distance from the imaging unit to the measure-distance target based on image data; a threshold setting unit that sets a threshold for distance; a detection unit that detects the measure-distance target as a detection object if the distance is shorter than the threshold set by the threshold setting unit; and a water supply control unit that causes the water faucet to discharge water in response to the detection unit detecting a detection object and causes the water faucet to stop supplying water in response to the detection unit not detecting a detection object. The threshold setting unit increases the threshold setting in response to the detection unit detecting a detection object.

Abstract: A method for removing odors produced in a toilet main unit of a toilet is made available. Specifically, a deodorizing unit having an air expulsion port and an air suctioning port is provided in a rear portion of the toilet main unit, and air is circulated by expelling air through the expulsion port such as to laterally swirl the air along an inner surface of the toilet's bowl, and by suctioning swirled returning air via the suctioning port. Deodorization is carried out in the course of circulating the air.

Abstract: Providing a toilet apparatus which can reduce an amount of water discharged into a waste collection tub. The toilet apparatus includes a toilet body (10) equipped with a toilet bowl (11) having a drain outlet (11A) in its lower part, a discharge part (20) communicating between the drain outlet (11A) and a waste collection tub (90) located below the toilet body (10), a drainage channel (30) branched from the discharge part (20), and a private parts cleaning device (50) assembled to the toilet body (10) and having a cleaning nozzle (51). When the private parts cleaning device (50) is actuated and an amount of cleaning water ejected from the cleaning nozzle (51) equals or exceeds a set amount, the cleaning water flowing into the toilet bowl (11) is caused to flow into the drainage channel (30) without being discharged via the discharge part (20) into the waste collection tub (90).

Abstract: Air suction device for a flush toilet configured to suction air from a toilet drain duct having a suction chamber dividing a tank body interior, a float in the suction chamber and an on-off valve closing an air inlet when the float lifts to prevent air flow from the toilet drain duct side into the suction chamber. The air inlet is higher than the water level in a toilet flushing standby mode. The on-off valve opens the air inlet to allow air flow form the drain duct side in the suction chamber when flush water in the tank drops such that the float is lowered form the raised position. An embodiment includes a valve chest, a float and attracting member for on-off valve manipulation. Another embodiment includes a valve chest with a small air flow manipulation hole.
