Title:
APPARATUS FOR CONTROLLING WATER LEVEL OF BATH TUB
Document Type and Number:
Japanese Patent JPH04353724
Kind Code:
A
Abstract:
PURPOSE:To achieve the setting of a standard water level for pouring water in a bath tub and the detection of the accurate amount of the poured water at each water level, to shorten the required working time for test operation and to achieve the automation for water pouring into the bath tub by using a general-purpose hot-water supplying device. CONSTITUTION:Hot water is supplied into a bath tub 4 from a hot-water supplying device 2 upon the instruction from a control panel 8. A water level H of a water level sensor 7 and the data of displacement (x) as the output are stored in a memory device 11. A standard water level Ho which is inputted from an input device 13 is registered in the memory device 11. A set level Hs which is inputted from a water-level setting device 2 is compared with the standard water level Ho, and the level of the poured water is controlled. When the detected signal of the flow rate q(t) of the supplied not water at a hot-water supplying plug is inputted from a flow rate sensor 6, the memory device 11 stores the amount Q of the poured water in correspondence with the water level H by the operation of Q=integral q(t)dt.
