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.

Sanitary washing device

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.

According to one embodiment, a sanitary washing device includes a toilet seat, a main part, a radio wave sensor, and a circuit board, wherein the main part is provided at a rear of the toilet seat; 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; and the circuit board includes a metal member and is positioned between the toilet seat and the radio wave sensor in a state in which the toilet seat is closed.

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.

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.

According to one embodiment, a toilet seat apparatus that includes a main part mounted at a rear upper part of a toilet, a toilet seat provided rotatably with respect to the main part, and a radio wave sensor being provided in the interior of the main part and using a radio wave to sense a human body; and in the state in which the toilet seat is lowered, the toilet seat covers the radio wave sensor, and the radio wave passes through the toilet seat and is radiated frontward of the radio wave sensor.

Toilet seat apparatus

A toilet apparatus according to an embodiment includes a toilet seat, a main part, a toilet, a tank, and a radio wave sensor. The toilet seat is pivotally supported by the main part to be openable and closable. The toilet is provided under the main part. The main part is placed on the toilet. The tank is provided inside the toilet. Water for washing the toilet is stored in the tank. The radio wave sensor is disposed higher than the tank. The radio wave sensor detects a human body by radiating a radio wave frontward of the main part.

Toilet apparatus

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.
