To solve a problem that the infrared ray is attenuated during being reflected by a wall surface and does not reach a light receiving part, when the wall surface of a bathroom has a dark color, though conventionally the infrared ray is horizontally emitted and reflected by the wall surface of the bathroom several times and reaches the light receiving part, when the infrared ray superposed with a control signal is emitted to the light receiving part of a bathroom drying machine mounted on a ceiling of a bathtub from a bath remote controller mounted on the wall surface of the bathroom.
This bath remote controller is configurated to refract the infrared ray emitted from an infrared ray light emitting diode 41 and upwardly deflect the same, so that much infrared ray is upwardly emitted.
