PROBLEM TO BE SOLVED: To provide a combustion device capable of preventing increase in exhaust resistance and enlargement of an exhaust mixing chamber to reliably mix carbon monoxide in a combustion exhaust, and capable of precisely detecting carbon monoxide concentration using a carbon monoxide detecting means.SOLUTION: An exhaust inlet 15 is provided in a lower plate 14 of an exhaust mixing chamber 8. An exhaust outlet 16 is provided in a rear side plate 10 of the exhaust mixing chamber 8. One half of the exhaust mixing chamber 8 is used as a first chamber 21, while the other half is used as a second chamber 22. A first partition plate 18 which partitions the first chamber 21 into a lower chamber 21a and an upper chamber 21b, and a second partition plate 19 for partitioning the second chamber 22 into a lower chamber 22a and an upper chamber 22b, are provided. The first partition plate 18 and the second partition plate 19 are inclined downward from a front side toward a rear side. The upper chamber 21b of the first chamber 21 is larger than the lower chamber 21a. The lower chamber 22a of the second chamber 22 is larger than the upper chamber 22b. A carbon monoxide detecting means 20 is provided in the upper chamber 21b of the first chamber 21. |
