Title:
MIXING DEVICE FOR HOT WATER AND COLD WATER
Document Type and Number:
Japanese Patent JPH05265565
Kind Code:
A
Abstract:
PURPOSE:To prevent an actual cold water and hot water mixed flow rate from being saturated at a value remarkably less than the upper limit of a set range of a target flow rate setting means when the pressure of supplied hot water or cold water decreases. CONSTITUTION:This device is a mixing device for hot water and cold water equipped with a control means 11 which operates flow rate valves 7, 8 so as to obtain mixture of cold water and hot water of target flow rate set by target flow rate setting means 12a, 12c based on the detection information of a flow rate detecting means 10 which detects a clod water and hot water mixed flow rate. In such a case, the control means 11 finds the target flow rate based on an instruction value set by the target flow rate setting means 12a, 12c. Also, the means corrects relation between the instruction values extending over all the setting ranges and the target flow rate setting the cold water and hot water mixed flow rate at that time as the target flow rate for the maximum instruction value when the flow rate valves 7, 8 are fully opened with the cold water and hot water mixed flow rate less than the target flow rate.
