TRAY MOVING ASSEMBLY OF A MICROWAVE OVEN FOR IMPROVING COOKING EFFICIENCY BY USING A HORIZONTALLY MOVING FIRST TRAY AND A SECOND ROTATING TRAY AT THE SAME TIME

摘要

PURPOSE: A tray moving assembly of a microwave oven is provided to utilize effectively an inner space of a cooking chamber by using a horizontally moving first tray and a second rotating tray. CONSTITUTION: A tray moving assembly of a microwave oven is composed of a first tray(410) having a receiving unit(411) recessed and arranged on the upside and a first recessed groove(412) dented and formed on the bottom side and reciprocating linearly toward the long side of a cooking chamber; a second tray(420) inserted rotatively in the receiving unit of the first tray and composed of a second recessed groove(422) dented and formed on the bottom side; at least two roller units(450) arranged along a wall in the receiving unit to support a peripheral surface and the bottom side of the peripheral surface of the second tray; a driving motor(430) generating rotary power to operate each tray; and a motion converting unit shaft-combined to the driving motor to supply rectilinear reciprocating motion power for reciprocating linearly the first tray and rotating motion power for rotating the second tray.
