METHOD OF DETECTING WATER LEVEL IN BATHTUB, AND ITS DEVICE, AND CIRCULATING FLOW CONTROLLER, AND CONTROLLER OF BATH WATER HEATER

摘要

PROBLEM TO BE SOLVED: To prevent the failure in detection of water level, by enabling it to circulate water geared to the work execution condition of each bathtub hot water supplier when circulating the water within the bathtub into a circulation pipe for circulation judgment or the like, and besides, bleeding air affecting the detection of water level. ;SOLUTION: A circulation circuit for the water within a bathtub to circulate is constituted, and the opening of a flow control valve 42 to adjust the quantity of circulating water provided within this circulation circuit is set by selecting a specified position out of plural positions different in aperture prepared in advance, and by the circulating water is circulated between the bathtub and the circulation circuit with a pump by the set position, and besides the air between the bathtub and a valve 44 is released upward through the valve provided above besides being downstream of a water level sensor 38, and then the valve 44 is closed and the water level within the bathtub is detected with a water level sensor 38.;COPYRIGHT: (C)1999,JPO
