Abstract: According to one embodiment, a sanitary washing device includes a main part, a toilet seat, and a radio wave sensor. The main part includes a toilet seat movable part including a metal. The toilet seat is supported by the toilet seat movable part to be rotatable. 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 includes a controller that determines a state of the user and outputs a signal relating to a determination result. The toilet seat movable part opens and closes the toilet seat based on the signal. The controller is positioned further rearward than the toilet seat movable part. At least a part of the controller overlaps at least a part of the toilet seat movable part in a frontward/rearward direction.

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: 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 toilet device includes a toilet seat device, a radio wave sensor, and a controller. The toilet seat device is provided on a toilet bowl. The controller is configured to operate the toilet seat device based on a signal outputted from the radio wave sensor. The radio wave sensor is being operable for detecting presence of a human body in a first area including front of the toilet seat device, detecting motion of a human body in a second area including the front of the toilet seat device and a region outside the first area, and determining sensing of the human body based on detection result of the motion of the human body and detection result of the presence of the human body.
