便器自動洗浄装置。[Scope of Claim for Utility Model Registration] A water faucet valve is opened based on human body detection by a reflective photoelectric sensor that receives reflected light emitted from a light emitting unit and a light receiving unit receives the reflected light, and automatically flushes water into the toilet bowl. In an automatic flushing device for toilet bowls, the light emitting section of the photoelectric sensor is provided with a lens to narrow down the light beam from the light projecting section to a predetermined range around the optical axis of the light projecting section. , a lens is provided in the light receiving section to narrow down the range in which the light reflected by the light receiving section can be received to a predetermined range centered on the optical axis, and the irradiation range of the light projected from the light projecting section and the range of the reflected light are The separation distance and direction of the light emitting part and the light receiving part are determined so that the range in which light can be received by the light receiving part overlaps within a predetermined detection distance range, and does not overlap outside the detection distance range. An automatic toilet cleaning device characterized by:
