<P>PROBLEM TO BE SOLVED: To provide a heating cooking device which can efficiently cool the inside of the cooking device. <P>SOLUTION: A heating cooking device in which a heat source is arranged below a top plate on a top face of a body comprises a space part serving as a long air channel extending in a cross direction formed inside the body. In the space part, electrical components included in a heating circuit of the heat source are arranged. In the body, an air duct constituting an air channel other than the space part is provided in the cross direction. In the air duct, a power module included in the heating circuit of the heat source and attached to a heat sink having cooling fins is provided. In the body, an electrically-driven cooling fan introducing cooling air from the outside of the body to flow into the air duct is provided. To the space part, cooling air introduced from the outside of the body other than the cooling air in the air duct is supplied to enable cooling of the electrical components by a flow of the cooling air. The heating cooking device is constituted such that the cooling air immediately after blown out from an outlet of the air duct cools heating coils. <P>COPYRIGHT: (C)2013,JPO&INPIT |
