Title:
HOT WATER TEMPERATURE CONTROLLER
Document Type and Number:
Japanese Patent JPH04195309
Kind Code:
A
Abstract:
PURPOSE:To obtain hot water temperature which satisfies desired temperature variation even when heat conduction is caused between hot water and a piping system by determining a driving quantity by multiplying a driving quantity which is inputted from a storage means by a coefficient corresponding to a switching period. CONSTITUTION:When a current is supplied from a hot water temperature control means 18 to a coil 26, a plunger 25 applies a bias force to a valve shaft 8. The current supplied to the coil 26 is varied to move the balance point of an automatic pressure control valve 3. The hot water temperature control means 18 inputs the signal of a hot water temperature detecting means 15 and the signal of a setting means 17 and then varies the current supplied to the coil 26 to control a mixing valve 23 so that the temperature of the hot water reaches set temperature. The mixed water after the temperature control passes through a mixing part 19 and a hot water temperature detecting means 15 detects the temperature of the hot water. When the temperature of the hot water is varied at a high speed, desired high-temperature-side hot water temperature is set by the setting means 17.
