Abstract:
To prevent the occurrence of microbial contamination, in a bath water purifying device having a purifying unit to purify bathtub water as circulation and heat insulation is effected.
The presence of water is confirmed by a water level detecting part 28 to detect a water level in a bathtub 15, and when a bathtub 15 is filled with water, a storage (using) time of water is measured by a time determinating part 28a, and a time in which bath water is contaminated by bacterium is reliably announced to a user by a water replacement announcing lamp 27b.
