Title:
HOT WATER SUPPLIER WITH ADDITIONAL BURNING APPARATUS
Document Type and Number:
Japanese Patent JPS6315032
Kind Code:
A
Abstract:

PURPOSE: To lower the cost for an automatic hot water supplying function by supplying water from a hot water supplying heat exchanger to a tank provided at a part of a hot water circulation circuit and opening a tank opening and closing valve to actuate a pump.

CONSTITUTION: At the time of an automatic hot water supply operation, a hot water supply control valve 24 is opened, whereby a water quantity sensor 29 for supplying hot water starts to count the water quantity and detects a fact that a predetermined quantity of water has been supplied, thus opening a tank opening and closing valve 31 and operating a pump 3. Further, simultaneously, a check valve 33 is closed and a bypass valve 32 is opened, whereby at the time of an automatic hot water supply operation, hot water flows along both outgoing and return pipes of a hot water circulation passage. Further, the quantity of automatically supplied hot water is counted by both the water quantity sensor 29 for supplying hot water and an additional burning water quantity sensor 36, and water quantity is adjusted by a supply hot water control valve 24 so that the water quantity counted by both sensor become equal. Further, the temperature of automatically supplied hot water is stably controlled by actuating a proportional control valve 13 based on a signal from a hot water supplying thermistor 18 and controlling the quantity of combustion of a hot water supply burner 14, thus automatically supplying hot water to a bathtub 4.
