Title:
Bath hot water supply system
Document Type and Number:
Japanese Patent JP6366530
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a bath hot water supply system capable of determining failure of a hot water supply flow sensor on the basis of a bath flow sensor or bath hot water supply performance.SOLUTION: In a bath hot water supply system in which bath-side and hot water supply-side flow channels are connected to a hot water storage tank 1 through a mixing valve 3, and which is constituted to supply hot water of a required temperature through the hot water supply-side flow channel while interrupting additional supply of hot water of high temperature, when the hot water is supplied to the hot water supply-side flow channel in a state of additionally supplying hot water of high temperature to the bath-side flow channel, a hot water supply flow sensor 9 is disposed in the hot water supply-side flow channel, a bath flow sensor is disposed between the mixing valve and the hot water supply flow sensor or in the bath-side flow channel, and failure of the hot water supply flow sensor is determined in a case where the bath flow sensor fluctuates over a prescribed range in a state in which no-flow is determined on the basis of a detection value of the hot water supply flow sensor, or a case where actual performance of hot water supply to the hot water supply-side flow channel is not detected by the hot water supply flow sensor even with detection of actual performance of hot water supply to a bathtub of the present day.SELECTED DRAWING: Figure 1
