Document Type and Number:
Japanese Patent JP2841565
Kind Code:
B2
Abstract:
PURPOSE:To enable a bath tub water level to be always kept at a comfortable water level by a method wherein when an increased water level value during taking a bath shows an increase higher than a predetermined water level within a predetermined time, the increased value is stored and added to the set water level and then an amount of adding to the set water level under a lowered water level during discharging of water from a bath tub is deleted. CONSTITUTION:When a person takes a bath during feeding of hot water into a bath tub 14 and a water level H is increased by 5cm, the water level is stored in a water level variation amount memory part 20 by a water level sensor output reading means 18a and a water level sensor output increasing or decreasing decision means 18b. The water level H of the bath tub is increased, the water level sensor output comparing and decision means 21 may compare data of a set water level HT + water level varying amount storage part 20 with data of the water level sensor 16 and then the hot water supply valve 6 is closed. In addition, when the person goes out of the bath tub 14 and the water level H is lowered, the water level descending state is discriminated by the water level sensor output reading means 18a and the water level sensor output increasing or decreasing decision means 18b and then the data of the water level varying amount storage part 20 is caused to be zero.
