AUTOMATIC BATH SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve facility of use by preventing a hot water filling level from excluding a set level due to unevenness of a sectional area modulus of a bathtub. SOLUTION: A controller 5 stores a value obtained by dividing a difference between a first water level in which a hot water level 8 is submerged and a second water level after a predetermined hot water supply amount is supplied from the first level by a predetermined hot water supply amount as a sectional area modulus of the bathtub in a memory 6, and calculates a necessary hot water supply amount up to the set water level based on the modulus of the bathtub stored in the memory 6 in operation after that. The controller 5 also controls a hot water supply unit 1 until a hot water amount detector detects a necessary hot water supply amount corrected by a correcting unit 7.
