<p>An air removing apparatus for an instantaneous water heating type heat exchanger, includes a main body, a diaphragm, and a check valve. The main body has, at an outer surface thereof, an inlet pipe and an outlet pipe, and the outlet pipe is arranged underneath the inlet pipe. The diaphragm is disposed in a horizontal direction in the main body between the inlet pipe and the outlet pipe, and the diaphragm has small holes perforated therethrough. The check valve is communicated to a top of the main body. The main body is formed of a plurality of divided members stacked into a layer. The inlet pipe is extended into the main body and communicated to an L-shaped injection pipe. The injection pipe has an inner end expanded into a semi-spherical shape. Each of the small holes of the diaphragm has a diameter of 0.5mm to 1.0mm. The check valve is constituted by a check valve casing and a valve. The valve includes a valve plate having a surface area wider than that of a stopper protrusion, and a valve shaft. The air removing apparatus of the present invention prevents a heating unit of a heater from being locally over-heated and broken or cracked. The temperature anomaly of the hot water discharged from the instantaneous water heater is reduced to thereby stabilize water temperature and protect the heater. The air removing apparatus of the present invention is provided with improved durability and operating reliability, and simple in configuration and excellent in efficiency.</p> |
