Abstract
Disclosed herein is a microwave oven, in which a tray within a cooking room is rectilinearly reciprocated in a lengthwise direction of the cooking room and is rotated, simultaneously, to cook food. This is achieved using a gear assembly including a main gear and a planetary gear. The gear assembly includes the main gear and the planetary gear, which are engaged with each other and are rotated. A diameter of the main gear and a diameter of the planetary gear may be equal to each other, and the main gear and the planetary gear respectively include eccentric shafts. The gear assembly effectively transmits power supplied by a motor to the tray, thereby allowing the tray to be rotated at a uniform speed and to be driven even using a motor having a small load capacity.
Claims25
A microwave oven, comprising:
- a main body having a cooking room;
- a tray disposed on a bottom surface of the cooking room;
- a motor to provide power to the tray;
- and
- a gear assembly changing the power supplied by the motor to drive the tray, the gear assembly including a main gear connected to the motor and rotatable, and a planetary gear engaged with the main gear and rotatable, at least one of the main gear and the planetary gear including an eccentric shaft having an eccentric distance from a center of the main gear and/or the planetary gear, respectively.
A tray apparatus of a microwave, the tray apparatus comprising:
- a sub-tray rectilinearly reciprocated in a lengthwise direction of a cooking room of the microwave;
- a rotary tray rotated on the sub-tray;
- a motor to provide power to the sub-tray and the rotary tray;
- and
- a gear assembly connected to the motor to operate the sub-tray and the rotary tray, the gear assembly including a main gear connected to the motor and rotatable and including an eccentric shaft, and a planetary gear engaged with the main gear and rotatable and including an eccentric shaft.
A tray apparatus of a microwave, the tray apparatus comprising:
- a sub-tray rectilinearly reciprocated in a lengthwise direction of a cooking room;
- a rotary tray rotated on the sub-tray;
- a motor to provide power to the sub-tray and the rotary tray;
- and
- a gear assembly connected to the motor to operate the sub-tray and the rotary tray, the gear assembly including a main gear connected to the motor and rotatable and including an eccentric shaft, and a planetary gear engaged with the main gear and rotatable.
A microwave oven, comprising:
- a main body having a cooking room;
- a tray disposed on a bottom surface of the cooking room, the tray being simultaneously rectilinearly reciprocated and rotated;
- and
- a motor to provide power to the tray to rectilinearly reciprocate and rotate the tray.
