PROBLEM TO BE SOLVED: To make both compatible in improving heat efficiency by excellent heat exchange between combustion gas and a cooking vessel and preventing exhaust of combustion exhaust gas after heat exchange to the user side. SOLUTION: A mantle cover 50 is installed to cover a space from above for making the combustion exhaust gas after heat exchange flow out of the periphery of the cooking vessel P. An annular exhaust gas body 40 communicating with a combustion exhaust gas space covered with the mantle cover 50, is arranged in a vessel body. A pair of exhaust cylinders 46 and 46 connected to a lower part of the annular exhaust gas body 40, are connected to an exhaust fan 47 by merging on the downstream side. Thus, an exhaust passage for sucking the combustion exhaust gas from the combustion exhaust gas space covered with the mantle cover 50 and exhausting the combustion exhaust gas outside the vessel body via the exhaust cylinders 46 and 46 from the inside of the annular exhaust gas body 40, is formed in the vessel body.
