<p>PROBLEM TO BE SOLVED: To provide a human body detector, capable of setting the boundary of a human body detection area itself and a toilet bowl electrical appliance, using the same. SOLUTION: When a human body enters the detection area of a human body detection sensor 22, a lid 16 of the toilet bowl is turned to and erect, and when the human body comes out of the detection area, the lid 16 is turned to fall. When a detection area regulating signal is inputted, the detection distance maximum value of the human body detection sensor 22 is reduced gradually and a distance L when the wall or the door of a bathroom is no longer detected for the first time, is calculated and (L-$50) mm is set as a maximum detection distance Lmax.</p> |
