Title:
TAP-CONTROLLED GAS HOT-WATER SUPPLIER
Document Type and Number:
Japanese Patent JPS61116236
Kind Code:
A
Abstract:

PURPOSE: To permit to control the necessary amount of heat, which is desirable for unpredictable external factors at all times, by a method wherein the ratio of combustion time to fire extinguishing time in an intermittent combustion period is determined based on the average value of the necessary amount of heat in the intermittent combustion period immediately before the determination.

CONSTITUTION: When an operating switch 17 is put ON, a delived hot-water temperature sensor 12 detects water temperature, a control base panel 15 begins the operation of the necessary amount F of heat, a pump 14 starts the rotation thereof simultaneously and a solenoid valve 8 is opened to start the intermittent combustion of a burner 2. Water, in a pipeline, flows to circulate from a feed water pipeline 3 through a heat exchanger 4 and a return pipeline 13 and is heated. The intermittent combustion of the burner 2 is controlled by the control base panel 15 by determining the ratio of combustion time t1 to fire extinguishing time t2 in respective intermittent combustion period based on the average value of the necessary amount F of heat in the intermittent combustion period immediately before the determination, therefore, the waster is heated up to a set temperature and the temperature is maintained. When a hot-water delivery valve is opened, hot-water, being heated up to the set temperature, is supplied to a hot-water supplying instrument 6 while newly supplied water is heated to the set temperature and is supplied.
