HOT-WATER SUPPLY HEAT EXCHANGER PROVIDED WITH A MIXING VALVE, AND ADAPTOR HAVING A BUILT-IN MIXING VALVE

摘要

The aim of the present invention is to provide a hot-water supply heat exchanger provided with a mixing valve, which has a simple configuration and enables the temperature of hot water to be easily controlled, and to an adaptor having a built-in mixing valve. To accomplish the aim, the hot-water supply heat exchanger of the present invention comprises: a heat-exchanging unit (100) for exchanging heat between the heating water supplied from a main heat exchanger (20) and cold tap water; a heating water inlet port (212) for feeding the heating water into the heat-exchanging unit (100); a heating water outlet port (214) for discharging the heating water after the heating water exchanges heat with the tap water in the heat-exchanging unit (100); a tap water inlet port (222) for feeding the tap water into the heat-exchanging unit (100); a hot water outlet port (224) for discharging the tap water, which has become hot water after the tap water has exchanged heat with the heating water in the heat-exchanging unit (100); and a mixing valve (230) for mixing the tap water fed via the tap water inlet port (222) with the hot water discharged via the hot water outlet port (224).
