<p><P>PROBLEM TO BE SOLVED: To surely detect incomplete combustion at any combustion part of a combined combustion device by a single carbon monoxide detecting means without increasing exhaust resistance so much. <P>SOLUTION: An inflow port 51 is formed on a bottom face of an exhaust collection chamber 5 in a state of laterally separated from an outflow port 52 to an exhaust cylinder, formed on an upper face, to allow the combustion exhaust from two combustion parts to join and flow into the exhaust collection chamber. The exhaust collection chamber 5 is partitioned into two chambers of a lower chamber and an upper chamber by a partitioning plate 53, a communication port 54 laterally extended to communicate the lower chamber and the upper chamber is formed on a front or rear part of the partitioning plate 53, and the outflow port 51 and the inflow port 52 are respectively partially overlapped to a projection face to the vertical direction, of the communication port 54. The carbon monoxide detecting means 7 is mounted to detect the concentration of carbon monoxide in combustion exhaust flowing to a part of the upper chamber positioned near the outflow port 52 within the projection face to an upper part of the partitioning plate 53. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
