Further, since there are a plurality of convex shapes 21 formed on the lower surface of the outer shell 15 in the peripheral portion of the intake port 19, even if the stored item 20 is attracted to the intake port 19, a certain cooling path is ensured. Because you can, there is no loss of inspiration.

  In this way, the intake port on the lower surface of the outer shell has a plurality of bridge shapes with openings on the side surfaces, and a convex shape that guides intake air to the intake port, so that the contents in the cabinet can be sucked into the intake port. Even if attached, a cooling passage for intake can be surely secured by one outer shell part.

  As described above, in the present embodiment, the intake port on the lower surface of the outer shell is provided with a plurality of bridge shapes having openings on the side surfaces, and a convex shape that guides intake air to the intake port. Even if the stored item is attracted to the intake port, it is possible to provide a low-cost and easy-to-assemble device that can secure a cooling passage for intake with one component. Moreover, even if the stored item in the cabinet is attracted to the air intake, the cooling performance is not greatly changed, and it is possible to provide a device that can cook as usual without reducing the heating power.

  In addition, although the built-in type apparatus is described here, the same effect can be obtained by a stationary apparatus having a suction port on the lower surface of the outer shell or a desktop type apparatus.
