  • Patent number: 6864470
    Abstract: A microwave oven incorporating toaster includes a tray provided on a tray support. The tray support moves forward and backward in inside the toaster. The tray support includes a bushing for moving within moving slots provided at both sidewalls of a toaster case. A connecting lever connects the bushing to a toaster door and translates a motion generated by operation of the toaster door when it opens and closes into a moving motion exhibited by the tray. A food item (e.g., a slice of bread, bagel, etc.) arranged on the tray may be inserted into, or removed from, the inside of the toaster by operating the toaster door.

  • Patent number: 6610970
    Abstract: A microwave oven incorporating a toaster includes a toaster door provided on a toaster panel for opening and closing at least one toaster entrance and a tray assembly. The tray assembly includes a tray support inside the toaster and at least one tray on the tray support for holding food items while they are heated. The tray includes at least one elevating bracket for maintaining a predetermined distance between the tray and the tray support. The microwave oven incorporating a toaster further includes a heater generating heat for toasting the food item and at least one connecting link between the toaster door and tray assembly for exerting a force on the tray assembly to move when the toaster door is opened and closed. In the microwave oven incorporating a toaster, each food item is positioned against a heater included therein so as to maximize the toasting performance of the toaster.
