  However, the heating cookers of Patent Documents 1 and 2 both have a cooling fan arranged at the rear of the main body, and the intake port is arranged at the rear of the main body. There was no concern that the hot air would be drawn from the air intake.

  Moreover, although the said structure of the heating cooker of patent document 3 aims at reduction of intake temperature by preventing the intake from the back of a main body, when a roaster is heated, the hot air which leaks from a roaster door or a roaster door Is not assumed.

  Therefore, since the configuration is such that hot air is sucked into the intake port by opening the roaster door during roaster heating, the intake air temperature rises, and there is a problem that the cooling efficiency of the components in the main body is reduced. It was.

  The present invention solves the above-described conventional problems, and is configured so that hot air leaking from the roaster door and hot air in the cabinet when the roaster door is opened are not sucked from the intake port arranged in front of the main body. An object of the present invention is to provide a cooking device that reduces the intake air temperature of the cooling fan and has good cooling efficiency.
