Title:
BATHTUB SYSTEM AND BATHTUB EXIT DETERMINATION METHOD
Document Type and Number:
Japanese Patent JP2023171357
Kind Code:
A
Abstract:
To provide a bathtub system capable of suppressing erroneous determination on bathtub exit.SOLUTION: A bathtub system includes a bathtub 10, a water level sensor disposed on the bathtub, capable of measuring a water level L in the bathtub, and a control device. A lower limit water level at which bathtub overflow is expected when entering the bathtub is predefined as an upper limit reference water level Lr0. The control device stores a water level as a reference water level Lr when the water level is stable beyond a preset stability time, stores an upper reference water level as a reference water level when the reference water level is above the upper limit reference water level, and determines the bathtub exit after storing the upper limit reference water level as the reference water level and when the water level is below the reference water level.SELECTED DRAWING: Figure 7
