Abstract: Disclosed is a power connector for a DC microwave oven, suitable for connecting power cords which are led from a DC power source and have positive and negative polarities, respectively, to a component arranged in a device chamber which is defined in a body of the DC microwave oven. The power connector comprises a connector body fixedly secured to a rear plate of the body of the DC microwave oven; power terminals for positive and negative polarities, the power terminals projecting into the device chamber from a rear surface of the connector body; and power cord connecting means projecting from a front surface of the connector body, for enabling the power cords which are led from the DC power source and have positive and negative polarities, to be connected thereto, respectively.

Abstract: Disclosed is a microwave oven having a tray which is arranged in a cooking chamber and on which a food to be cooked or a vessel having accommodated therein a food to be cooked is placed and a tray driving section which is disposed in a driving chamber for transferring rotating force to the tray. The microwave oven comprises tray supporting means for preventing the tray from being released from an original installation position. The tray supporting means includes a first coupling portion which is formed on a driving shaft of the tray driving section, a second coupling portion which is press-fitted around the first coupling portion, and supporting arm portions which extend from the second coupling portion in a radial direction so as to be respectively engaged with an edge of the tray.

Abstract: Disclosed is a parts arrangement structure for a DC microwave oven which is formed by a combination of an upper panel, a lower panel and a rear panel, a space inside the DC microwave oven being divided into a device chamber in which a magnetron and an air guide are placed and a cooking chamber in which a rotating motor for rotating rollers and a turntable is placed, the DC microwave oven having a control panel which closes a front end of the device chamber. The parts arrangement structure comprises a high voltage transformer and an inverter circuit board mounted to the lower panel inside the device chamber; and at least one high voltage capacitor mounted to the lower panel below the cooking chamber.

Abstract: A microwave oven wherein at least a microwave cooking mode and an electric resistance heater cooking mode can be selected by a user. A tray for supporting foodstuff can be raised and lowered and rotated about a vertical axis. A weight measuring mechanism determines the weight of foodstuff on the tray. During a cooking sequence, an operator selects a cooking mode, and the weight of foodstuff is measured. A controller determines a desired cooking elevation as a function of the cooking mode and weight of the foodstuff. A rotation mechanism begins to rotate the tray, and then the rotating tray is raised to the desired elevation, whereupon a cooking operation is performed while the tray is rotated at the desired elevation. At the end of the cooking operation, the tray is lowered to its initial position while still being rotated.

Abstract: A microwave oven includes a cooking chamber and a steam generator for supplying steam thereto for preventing food from drying out during cooking. The steam generator includes a water storage tank and a pair of spaced-apart electrodes mounted in the tank for producing an electrical current across the water in the tank, thereby heating the water to form steam. The water may contain an electrical conducting substance such as sodium chloride to facilitate generation of the electrical current.

Abstract: A microwave oven includes a cooking chamber to which a high frequency can be supplied. An electric heater is disposed in the cooking chamber for cooking by radiant heat. The heater is vertically movable by a motorized power transfer mechanism between upper and lower positions for regulating the intensity of the radiant heat cooking.
