Title:
BATH AND HOT WATER SUPPLYING APPARATUS
Document Type and Number:
Japanese Patent JP3754503
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a bath and hot water supplying apparatus for conducting an accurate water level keeping operation and an automatic hot water filling operation by detecting a fault of a water level sensor such as a pressure sensor during operating of a temperature keeping mode.
SOLUTION: The apparatus comprises a pressure sensor 13 for detecting a water level in a bathtub, and means for filling hot water to a set water level in the bathtub based on its detected level and P-Q relation data of the level P in the bathtub stored in a data storage unit 25. In this case, an output of the sensor 13 is monitored by a water level monitor 24 during operating of a temperature keeping mode after filling the hot water. When a level change exceeds an allowable change value, whether a level change occurs or not during a set time previously given before or after the level change is judged by a P-Q data correcting unit 26. When no level change occurs during the set time, the relation data is corrected by the level change amount by a water level changing method. And, hot water filling and water level keeping operations are conducted by an operation controller 23 based on the corrected relation data.
