摘要

PROBLEM TO BE SOLVED: To provide a small-sized device. ;SOLUTION: A combustion plate 1 is adhered to a front opening section of a frame body 1. A plurality of venturi mixers 3, for example, three venturi mixers are arranged side by side in a predetermined space from each other at a substantial central part of the frame 2 in parallel with the combustion plate 1. An air chamber 4 provided with an opening 41 connected with the air supplying section is arranged at a rear side of the venturi mixer 3. A mixture gas chamber 5 is arranged between the venturi mixer 3 and the combustion plate 1. Then, an air inlet hole 31 of the venturi mixer 3 is placed adjacent to the air chamber 4, a mixture gas discharging hole 32 is placed adjacent to a mixture gas chamber 6. Each of fuel gas suction holes 34 opened at four locations around the most-narrow throat section 33a of an air passage 33 is communicated with the fuel gas chamber 5 through a fuel gas passage 35.;COPYRIGHT: (C)1998,JPO
