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.
Claims8
A toilet seat device comprising:
- a toilet seat;
- a toilet seat open/close sensor which senses whether the toilet seat is in an opened state or a closed state;
- a Doppler sensor using radio waves;
- and
- a controller,
- the controller being capable of performing
- a room-entering determination process of sensing approach of a user to the toilet seat based on a sensing signal outputted from the Doppler sensor,
- a usage determination process of determining urination when it is sensed that the toilet seat is in the opened state, after the room-entering determination process, based on a sensing signal outputted by the toilet seat open/close sensor,
- a leaving determination process of sensing that the user leaves from the toilet seat, after the use determination process, based on the sensing signal outputted by the Doppler sensor, and
- an post-use operation process of outputting a flushing signal for flushing a bowl part of a toilet stool after the leaving determination process,
- the controller performing the post-use operation process when it is sensed by the leaving determination process that the user leaves from the toilet seat after determining urination in the usage determination process,
- the controller not performing the post-use operation process when it is sensed by the leaving determination process that the user leaves from the toilet seat after not determining urination in the usage determination process.
