Kind Code:
B2
Abstract:
To accurately detect leaving-from-bathtub after getting-into-bathtub by using a water level sensor of a bathtub without forcibly increasing/decreasing water in the bathtub.SOLUTION: Getting-into-bathtub and leaving-from-bathtub are detected on the basis of a water level detection value of a bathtub by a water level sensor. The getting-into-bathtub at a time t2 is detected according to a rise amount ΔXtn of a water level detection value with respect to that Tx (seconds) before, becoming a determination value Xth or higher. When the getting-into-bathtub is detected, a leaving-from-bathtub determination value Xout is determined by using the water level detection value before the boing-into-bathtub. In a getting-into-bathtub state after the detection of the boing-into-bathtub, the leaving-from-bathtub is detected according to the present waver level detection value becoming lower than the leaving-from-bathtub determination value Xout.SELECTED DRAWING: Figure 3
