Control apparatus for water temperature and water flow rate

Abstract

A control apparatus for water temperature and water flow rate includes a mixing valve adapted to be supplied with hot water and cold water from a hot water source and a cold water source, respectively, and delivers mixed water. In addition, the control apparatus includes a flow rate controller disposed to a system for delivering the mixed water from the mixing valve to a place where it is required and a controller for operating the mixing valve and the flow rate controller. This controller includes: a switch for discharging water and stopping the discharge of water, a setter for the water flow rate and the water temperature of the mixed water, a standard value memory for storing the standard water temperature and the standard water flow rate of the mixed water, a selected value memory for storing the water temperature and the water flow rate selected by the setter, a timer which is started upon a water stopping operating of the switch, and a signal selection that outputs an operation amount signal based on slected values when the water discharge operation is made before the elapse of a predetermined amount of time after the water stopping operation to the mixing valve and to the flow rate control, and operation amount signals based on the standard values when the water discharging operation is made after the elapse of a predetermined amount of time after the water stopping operation to the mixing valve and the flow rate control.
