Abstract: According to one embodiment, a sanitary washing device includes a main part and a sensor. The main part includes a nozzle and a flow channel switching unit. The flow channel switching unit includes a motor and switches a flow channel of water flowing toward the nozzle by an operation of the motor. The sensor is provided in an interior of the main part and includes a transmitter/receiver and a controller. The transmitter/receiver radiates a radio wave and receives the radio wave reflected by an user. The controller determines a state of the user based on the radio wave received by the transmitter/receiver and outputs a signal relating to a determination result. The main part controls an operation of the flow channel switching unit and the nozzle based on the signal. The nozzle is positioned between the sensor and the motor in a width direction of the nozzle.

Abstract: According to one embodiment, a sanitary washing device includes a main part, a toilet seat, and a sensor. The toilet seat is supported to be rotatable. The sensor is provided in an interior of the main part and uses a radio wave to detect a user in front of the main part. A position of the sensor does not change. In a state in which the toilet seat is closed, the user in front of the main part is detected by the sensor in a first region and a second region higher than the first region. In a state in which the toilet seat is open, the user in front of the main part is detected by the sensor in the first region without the user in front of the main part being detected by the sensor in the second region.

Abstract: A toilet apparatus according to an embodiment includes a human body detector and a controlled part. The toilet apparatus is mounted to a toilet. The human body detector radiates a radio wave and detects a human body based on the signal that is obtained. The human body detector outputs a control signal based on the detection result. The controlled part is controlled based on the control signal. The human body detector has two or more establishment times from when the signal is obtained until when the detection result based on the signal is established.

Abstract: A sanitary washing device according to an embodiment includes a toilet seat, a main part, and a radio wave sensor. The toilet seat is provided on a toilet. The toilet seat is pivotally supported by the main part. When the toilet seat is closed, the user in front of the main part is detected by the radio wave sensor in a first region, and in a second region higher than the first region. When the toilet seat is open, the user in front of the main part is not detected in the first region by the radio wave sensor, but the user in front of the main part is detected in the second region by the radio wave sensor. The position of the radio wave sensor is not changed between the state in which the toilet seat is open and the state in which the toilet seat is closed.

Abstract: According to an embodiment, a toilet device includes a detector configured to detect at least one of a water level inside a flush toilet or an indicator associated with the water level, a clog determiner determining a clog state of the flush toilet based on a detection result of the detector, and a controller determining, based on a determination result of the clog determiner, whether or not to prohibit a flushing water supply to the flush toilet. The controller sets a flush prohibition time at least after the flushing water supply to the flush toilet has ended. A flush operation for flushing the flush toilet not is accepted temporarily in the flush prohibition time. The clog determiner determines the clog state of the flush toilet based on the detection result of the detector within the flush prohibition time or directly after the flush prohibition time.
