PROBLEM TO BE SOLVED: To provide a heating cooker capable of purifying exhaust without using a heating source exclusively used for a catalyst and saving energy, by making a temperature of the catalyst quickly reach an activation temperature by effectively transferring exhaust heat from a heating source of a heating chamber to the catalyst, and simultaneously keeping the activation temperature by suppressing heat radiation.SOLUTION: As a first exhaust passage 23 is defined between a rear wall surface 20 of the heating chamber 11 and a first partitioning wall 22 disposed at its outer side, and a second exhaust passage 27 is defined between the first partitioning wall 22 and a second partitioning wall 26 disposed at its outer side, heat conduction through the rear wall surface 20 of the heating chamber 11 and the first partitioning wall 22, and convection heat due to flow of the exhaust 18 are effectively absorbed, thus the activation temperature of the catalyst 24 can be kept and the stable oxidation decomposition performance can be ensured. |
