Title:
COOKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/055132
Kind Code:
A1
Abstract:
Conventional cooking devices for commercial use are more frequently used than those for domestic use. This results, in a commercial-use cooking device, in a short service life of a punched plate located at the bottom surface of a cooking chamber and shielding a microwave while allowing a magnetic flux to pass. In the cooking device of the invention, a circular opening is provided in a bottom plate (71) forming the bottom of a cooking chamber, and an annular bottom-plate fitting (73) to which a punched plate (72) is fused is removably attached to the opening. The bottom-plate fitting (73) is fixed to the bottom plate (71) by a combination of a fixation section (75) and a press-contact section (78). In the fixation section (75), welded bolts secured to the bottom plate (71) and nuts are screwed with each other for the fixation, and in the press-contact section (78), projections (73b) are simply pressed against the bottom plate (71). The construction sufficiently achieves improved replacement/repair work efficiency of the punched plate and strength required for the bottom surface of the cooking device.
