<p><P>PROBLEM TO BE SOLVED: To provide a cooker capable of enhancing cooling efficiency and reducing noise and vibration. <P>SOLUTION: A centrifugal fan 5 includes a plurality of blades 11, shrouds 12 connecting a plurality of the blades 11 near a fan suction port 7 and formed with wall surfaces for guiding cooling wind from a suction part to an approximately outer peripheral direction inside the centrifugal fan 5, first/second main plates 13a, 13b formed with wall surfaces for connecting a plurality of the blades 11 on the downstream side of the cooling wind and guiding the wind from the suction part to the approximately outer peripheral direction, and a boss 13c for mounting a motor 9. Outer diameters of the shroud 12 are composed to be larger than the outer diameters of the main plates 13. The centrifugal fan 5 is integrally formed of the shrouds 12, the blades 11, the first main plate 13a, and the boss. The centrifugal fan 5 is joined to the second main plate 13b. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
