POWER SAVING-TYPE SMALL SIZE HOT-WATER BOILER FOR SIMPLFYING STEAM DISCHARGE

摘要

An energy-saving small-size hot-water boiler is provided to prevent the water heated in the heater cylinder from flowing back due to the thermal expansion by installing a spring check valve on the inlet of the heater cylinder and connecting a hot water discharge container having a steam outlet in which an inner valve is opened/closed by a spring to the outlet of the heater cylinder. An energy-saving small-size hot-water boiler comprises a water tank(1); and a U-type circulation tank(2) which is integrally protruded from the water tank and includes an outside circulation hole to which a return pipe of a heating pipeline in which a check valve(C) is equipped on the inlet side is connected and an inner circulation hole(2a) to which a heater cylinder(10) in which a check valve is installed on the outlet side is connected. An inlet pipe of the heating pipeline which is connected to an outlet of the heater cylinder. A steam outlet(30) in which an inner valve(31) is opened and closed by a spring is connected to a hot water discharge container(20) through an upper pipe(21) protruded to the inside of the water tank.
