Abstract: According to one embodiment, a sanitary washing device includes a main part, a toilet lid, and a radio wave sensor. The main part includes a toilet lid opening/closing part including a metal. The toilet lid is pivotally supported by the toilet lid opening/closing part to be rotatable with respect to the main part. The radio wave 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. The radio wave sensor is positioned further frontward than the toilet lid opening/closing part. At least a part of the radio wave sensor overlaps at least a part of the toilet lid opening/closing part in a horizontal direction.

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: 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 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.

Abstract: A remote control device according to an embodiment includes an operation button, a generator, an electrical storage part, electronic paper, and a controller. The operation button is for remotely operating a wet-area device. The generator generates electrical power by utilizing energy when the operation button is pressed. The electrical storage part stores the electrical power generated by the generator; the electronic paper displays a setting state of the wet-area device. The controller controls a refresh and a display-switching of the electronic paper by utilizing the electrical power stored in the electrical storage part. The operation button is marked with information showing a function of the operation button. The controller performs the refresh in the case where the function is not realized when the operation button is pressed.
