PROBLEM TO BE SOLVED: To reduce the pre-heating time of a heating chamber and improve the heat efficiency in a heating cooker which circulates hot air emitted from heating means in the heating chamber to cook a heated object.SOLUTION: A heating cooker includes: a heating chamber 10 which stores a heated object F; heating means 13 which generates hot air; a combustion chamber 20 in which the heating means 13 is disposed; a circulation fan 14 which circulates the hot air in the heating chamber 10; a fan motor 15 which rotationally drives the circulation fan 14; a motor housing chamber 35 in which the fan motor 15 is disposed; a cooling fan 16 which takes outer air of the main body into the motor housing chamber 35; an exhaust passage 30 which guides the hot air in the heating chamber 10 to the outside of the main body; a cooling passage 37 which causes the outer air taken into the motor housing chamber 35 to pass along a constitution wall 302 of the exhaust passage 30; and a return passage 38 which guides the outer air sent into the cooling passage 37 into the combustion chamber 20.SELECTED DRAWING: Figure 1 |
