TOILET SEAT DEVICE

Japanese Patent JP2014014424

A

To expand a detection range of a human body detection sensor installed in a remote controller.

A toilet seat device includes a body 200 containing electric functions and installed on a toilet bowl 110, and a remote controller 400. The remote controller 400 is provided with a human body detection sensor 300. The human body detection sensor 300 is provided with a pyroelectric sensor 310 having a light receiving surface 311, and a mirror 320. The light receiving surface 311 is arranged inside the surface of an outer hull of the remote controller 400, a part of a reflection surface is arranged outside the surface of the outer hull, and a cover covering the human body detection sensor 300 is formed so that its peripheral part is thinner than its central part, whereby the light receiving surface 311 of the pyroelectric sensor 310 can directly receive infrared rays emitted from a human body and receive the infrared rays by making them reflect on the reflection surface of the mirror 320, which can expands a light receiving range to expand a human body detection range.
