<P>PROBLEM TO BE SOLVED: To inexpensively provide a small heat accumulating heat exchange type burner unit usable even for a burner for cooking. <P>SOLUTION: A fuel supply nozzle for putting out a flame in a combustion chamber 3a and heat accumulating heat exchangers 13, etc., are installed in a unit body 3 having the combustion chamber 3a. A part opposed to a heating object 9 of a wall part of the unit body 3 is composed of heat radiation plate materials 5A to 5C for radiating radiation heat to an external part by being heated by heat in the combustion chamber 3a. A support structure 23 of the heat radiation plate materials 5A to 5C is formed as a quasi-sealed support structure for allowing leakage of exhaust gas from the inside of the combustion chamber 3a in a range for not remarkably reducing a heat exchange rate of the heat accumulating heat exchangers. <P>COPYRIGHT: (C)2003,JPO |
