An automatic bidet automatically washes a user, after they have eliminated, while sitting on a toilet. The bidet uses a camera connected to a computer, to identify a user's gender, and to identify elimination from the users front or back location, the information is used direct water to the user's elimination positions, after eliminating. When washing the user, an automatic water aiming device, can also be used, to automatically target and direct water, to the user's elimination positions, without the user, having to move their body, to the water stream. A bottom air drier automatically dries the user's bottom, after washing. The automatic bidet decreases the transmission, of possibly harmful bacteria and viruses, to the user, by relieving them of manually having to operate, a possibly bacteria contaminated bidet control panel. Bidet automation frees the user, from expending effort, and needing knowledge to operate a bidet.

The present invention relates to a control device (1), in particular for a washroom facility, the device comprising: an actuator (2); a sensor (4) configured to detect the presence of a user in the proximity of the sensor (4); and a control circuit (6) receiving, as input, signals from the sensor (4) and configured to control the actuator (2).

The sensor (4) comprises: an emitter (10) configured to emit an infrared signal; and a receiver (8) configured to detect the infrared signal emitted by the emitter (10).

The invention also provides a washroom facility, a substance dispenser, and a hair dryer or hand dryer, including such a control device (1).

A method for controlling actuations of an automatic toilet flushing mechanism compares manual flush timestamps, latch open timestamps and latch close timestamps in association with uses of a toilet stall to generate a stall use profile. Automatic toilet flushing may be controlled based on the stall use profile. Stall usage data, toilet usage data and/or water usage data may be collected and provided for improved maintenance and water conservation.

A water discharge apparatus including a water discharger, a water supply path, an opening/closing valve, a photoelectric sensor, and a controller, the photoelectric sensor projects detection light, receives a reflected light of the detection light, and outputs a received signal corresponding to a light reception amount of the reflected light, the controller detects an existence or absence of an object based on the received signal and controls opening and closing of the opening/closing valve according to a detection result of the object, the photoelectric sensor includes a sensor main body and a conductive member, the sensor main body includes a light-projecting element and a light receiving element, and the conductive member covers a front of the light receiving element, is formed in a sheet configuration, is light-transmissive, is conductive, and is electrically connected to a reference potential of the sensor main body.

An optical system includes one or several passive optical detectors sensitive to ambient (room) light for controlling, for example, the operation of automatic faucets or automatic bathroom flushers. The passive optical sensors provide signals to flow controllers, including control electronics and flow valves and require only very small amounts of electrical power for sensing users of bathroom facilities, and thus enable battery operation for many years. To control the operation of automatic faucets or automatic bathroom flushers based on ambient light, the controller executes novel algorithms.

According to one embodiment, a sensor device includes a transmitter part, a receiver part, a signal generation part, and a determination part. The transmitter part is configured to emit a radio wave outside as a transmission wave. The receiver part is configured to receive a reflection wave reflected by an object as a reception wave. The signal generation part is configured to generate a first output signal generated based on the transmission wave and the reception wave, a second output signal provided with a phase different from that of the first output signal, and a third output signal generated based on the first output signal and the second output signal. The determination part is configured to determine presence or absence of an object based on the first output signal, the second output signal, and the third output signal.

Exemplary embodiments of a pet toilet are provided. A pet toilet is provided having a base, a standing surface provided on the base configured to allow a pet to stand on the standing surface, a first flush mechanism to provide water for flushing the standing surface, a rim tube connected to the first flush mechanism configured to provide water from the first flush mechanism to the standing surface, and at least one water outlet disposed on the rim tube for providing water from the first flush mechanism to the standing surface. The flush mechanism can be an automatic flush mechanism triggered by one or more motion sensors. The standing surface can have a concave surface.

A flushing device (1) for a sanitary article (2), in particular a urinal or a toilet, said flushing device comprising a control unit (3), and a flushing valve (4) that can be controlled by means of the control unit (3) for controlling a flushing procedure, wherein a fluid for flushing or for cleaning the sanitary article (2) is introduced during a flushing procedure, wherein it is possible by means of the control unit (3) to predetermine a flushing regime for the flush activation. The control unit (3) further comprises a temperature sensor (5) for detecting the ambient temperature (T), wherein the temperature sensor (5) is connected by way of a data channel (7) to the control unit (3) and wherein the flushing regime can be adjusted on the basis of the ambient temperature (T).

According to one embodiment, a toilet seat device includes a toilet seat, and a Doppler sensor using radio waves. An opened state of the toilet seat is sensed when approach of a user to the toilet seat is sensed based on a sensing signal outputted by the Doppler sensor. It is regarded that use is in progress for urination by the user when the toilet seat is in the opened state. In a state of being regarded that use is in progress for urination, a post-use operation is performed after sensing leaving of the user from the toilet seat based on the sensing signal.
