<P>PROBLEM TO BE SOLVED: To provide a burner A in which a burner body 10 is integrated with a supporting member (trivet) for supporting an object C to be heated. <P>SOLUTION: The burner A includes: the burner body 10 in which a space 13 between an inner cylinder 11 and an outer cylinder 12 is made a gas flow path; and a rod member 50 while being biased upward inside of the inner cylinder 11. The rod member 50 is also used as a trivet and located at an upper limit position protruded from the tip end of the burner body 10 just by a fixed distance while an external load does not act thereon, and in such a state, combustion gas supply is cut off. When an external load greater than biasing force acts in a direction confronting the biasing force, in accordance with the load, the rod member is moved toward the base part side of the burner body 10 and combustion gas can be supplied. Accordingly, in a heating cooker B, since a number of pieces of burners A are dispersedly arranged uniformly over the whole heating cooking range on a top plate 72, even when the object C to be heated in any arbitrary shape is placed at any arbitrary position within the heating cooking range on the top plate, efficient heating can be performed on the object C to be heated. <P>COPYRIGHT: (C)2013,JPO&INPIT |
