Document Type and Number:
Japanese Patent JP3331164
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a heat exchanger from being deteriorated or generate uncomfortable feeling to a user during controlling a temperature keeping of hot water within the heat exchanger. SOLUTION: A hot water feeding device 1 is comprised of a heat exchanger 6 heated by a heating means 5; a hot water feeding pipe 11; a hot water feeding temperature sensor 14; a heat exchanging temperature sensor 15 for detecting a temperature of hot water near an outlet of the heat exchanger 6; a flowing water sensor 10 for detecting whether or not a flowing water passing through the heat exchanger is present; and a hot water feeding control means 31 for performing a hot water feeding control and a temperature-keeping control in which a temperature of hot water within the heat exchanger 6 detected by a heat exchanging sensor is kept in a range from a predetermined temperature-keeping start temperature to a temperature-keeping target temperature. The hot water feeding control means 31 does not operate the heating means 5 even if the temperature detected by the heat exchanging temperature sensor 15 is lower than the temperature keeping start temperature until the predetermined time elapses when the heating means 5 is stopped in its operation in case that the temperature-keeping control is performed.
