Filed: 1990-11-27
Abstract: PURPOSE:To prevent hot water from flowing out at the start of water flow by the arrangement such that a heat receiving element of a carburetor is provided in a combustion chamber formed from a burner head and a heat exchanger and a body of the carburetor is positioned outwardly from the exchanger so that heat radiation due to an upward air stream of the carburetor while water is not fed to the exchanger is reduced. CONSTITUTION:If a carburetor 20 is kept at specified temperature, upward air stream occurs due to the heat of the carburetor 20 and that of a burner head 32 being heated by the carburetor 20. Since the carburetor 20 and burner head 32 are parallelly disposed, the former being positioned higher than the latter, the stream is very weak, so that the amount of heat which is discharged from the carburetor 20 into a combustion chamber 38 by the action of the stream to heat a heat exchanger 37 is small and hence water in the exchanger 37 is not heated largely. Since only such area of the carburetor 20 facing a heat receiving element 26 and the head 32 is exposed to the chamber 38 and a body 31 of the carburetor 20 is positioned outwardly from the exchanger 37, heating due to the heat of the carburetor 20 is little, while water is not fed to the exchanger 37.
