<p><P>PROBLEM TO BE SOLVED: To provide a toilet seat device that does not need a temperature detection device special to detect the ambient temperature of a seating surface outside the toilet seat, and can maintain the seating surface at a desired temperature against the fluctuation of the ambient temperature of the seating surface. <P>SOLUTION: The toilet seat device includes: a toilet seat 3 that has a seating surface 3a; a heating element 6; a temperature detection device 7; a seating surface temperature setting means 5a; an aim value setting means (in CPU 8) that sets the aim value Tba of the temperature Tb of a rear surface 3b side of the seating surface 3a; a control means 9 that controls the power P supplied to the heating element 6 so that the temperature Tb detected by the temperature detection device 7 may become the aim value Tba; a mean power calculation means (in CPU 8) that calculates the mean power Pa supplied to the heating element 6 after the temperature Tb becomes the aim value Tba; and the aim value change means (in CPU 8) that changes the aim value Tba so that the seating surface 3a may maintain a desired temperature Tsa based on the mean power Pa that has the correlation of an ambient temperature To of the seating surface 3a, the desired temperature Tsa, and the aim value Tba. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
