Linearly reciprocating tray for microwave oven

摘要

A microwave oven in which a power transmission transmitting driving force of a motor moves a tray right and left without direct contact with the tray. The microwave oven includes a support disposed between a bottom plate and the tray to support the tray and the power transmission transmitting driving force of the motor to the support such that the support linearly travels. The shape of an oval guide hole formed in the support is changed to adjust the stopping time of the support at the rightmost or leftmost side. The tray linearly travels together with the support when the support linearly travels. The microwave oven further includes a tray restriction device or a tray moving device for guiding the linear movement of the tray. The tray restriction device and the tray moving device are implemented by locking steps, grooves, protrusions, or rollers.
