FIG. Thus, it has been proposed to provide a water droplet receiver 9 at the lower front portion of the cooking machine body 5 (see, for example, Patent Document 1).
[0004]
[Patent Document 1]
Japanese Utility Model Publication No. 3-115318
The water droplet receiving part 9 shown in FIG. 7 is horizontally inclined forward from the front edge of the inclined plate part 9a, and the inclined plate part 9a extending diagonally forward and downward from the front edge of the bottom wall 5b constituting the cooking machine body 5.
