Title:
HOT AND COLD WATER MIXING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/122153
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a hot and cold water mixing device (1) which is capable of preventing a reduction in the measurement accuracy of a flow rate sensor (21). In this hot and cold water mixing device (1), a flow rate sensor (21) is installed in a flow path having the greatest flow rate from among a hot water supply path (11) and a cold water supply path (12), and at least a first temperature sensor (231) and a second temperature sensor (232) are respectively installed in at least two flow paths from among the hot water supply path (11), the cold water supply path (12), and a mixed water path (14). A hot and cold water adjustment unit (13) adjusts the hot water and cold water mixing amount by using the measured values of: the flow rate sensor (21) installed in the flow path having the greatest flow rate; a mixed water path flow rate sensor (22); and the at least first temperature sensor (231) and second temperature sensor (232).
