Abstract

An object of the invention is to provide a hot and cold water mixing device for reducing degradation in the measurement accuracy of a flowmeter. In the device according to the invention, the flowmeter is disposed in one of a hot water supply path and a cold water supply path, having a higher flow rate. At least first and second temperature sensors are individually disposed in at least two of the hot and cold water supply paths and a mixed water path. A hot and cold water adjustment unit adjusts a mixing volume of hot water and cold water based on measurement values of the flowmeter disposed in one of the flow paths having a higher flow rate, a mixed water path flowmeter and at least the first and second temperature sensors.
