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 has a cooking chamber in which a tray is provided for supporting food to be cooked. The tray is rotatable and can be raised and lowered. Cooking can be performed by microwaves and/or an electric resistance heater disposed in the cooking chamber. A sensor disposed in the cooking chamber detects a condition wherein food on the rising tray is at a height corresponding to that of the heater. In response to the sensing of such a condition the heater is turned off, a mechanism for raising the tray is also turned off, and a warning is emitted.

Abstract: A microwave oven includes a cooking chamber in which a turn table is disposed for rotation about a vertical axis, and vertical up/down movement along the axis. The turn table has an axle extending downwardly therefrom along the axis. The lower end of the axle rests on a cam surface of a rotary cam member whereby the cam surface causes the axle (and thus the turn table) to alternately move up and down when the rotary cam member is rotated by a first motor. A second motor is connected to the axle to simultaneously rotate the axle and turn table. A traction member is fixed to the rotary cam and overlies a portion of the axle. The traction member extends along a portion of the cam surface which causes the axle to move downwardly, whereby the traction member can pull the axle downwardly if the axle does not properly gravitate downwardly.

Abstract: A microwave oven has a food tray which can be both rotated and elevated. A weight sensing unit senses the weight of the tray and any food thereon, for controlling the operation of a tray elevation/rotation mechanism. The tray is not elevated if the weight of the food is detected to be greater than a predetermined elevation weight, in order to prevent excessive pressure from being applied to the elevation/rotation mechanism and the weight sensing unit. If the weight of the food is detected to be greater than a maximum possible cooking weight, no cooking is performed, and an error signal is displayed.

Abstract: A microwave oven has a cooking chamber in which a vertically movable turntable is disposed. During the onset of a cooking operation, a control mechanism automatically raises the turntable in step-by-step fashion, and the amount of high frequency waves reflected from the cooking chamber is detected at each vertical position of the turntable. Then, the vertical position of the turntable at which the detected amount of reflective frequency was the lowest is determined, and the turntable is set at that position to continue the cooking operation. If the detected amount of reflective frequency changes, a new vertical position of the turntable at which the amount of reflective frequency is lowest, is re-determined, and the turntable is set at that new position.

Abstract: An improved method and apparatus for safely and rapidly rewarming large quantities of frozen or refrigerated blood combines microwave, or radio frequency radiation, heating with a forced air system. Forced air is flowed over units of blood or tissue from those units that will absorb the most microwave energy, generally those units closest to the source of microwave energy, to those units that will absorb the least microwave energy, generally those units furthest from the source of microwave energy. The forced air initially thaws the closest units so that they begin to absorb significant microwave energy. The forced air, preferably chilled, then prevents overheating of those closest units by transferring heat to more distant units, beginning their thawing and contributing to their rewarming. The microwave energy source is turned off when the output temperature of the forced air reaches a preselected temperature and the flow of forced air continues until the output temperature stabilizes.

Abstract: A fabric drying system has an exterior housing and a rotating chamber for containing fabric laden with moisture that is to be dried and uses a combination of microwave energy and an auxiliary convection air heater to heat and vaporize the moisture and expel it with exhaust air so as to dry the fabric. In addition, the fabric drying system employs energy efficiency devices that permit the system to dry the fabric using the least amount of energy. Heat energy from the exhaust air is transferred to the intake in a heat exchanger. Additionally, heat energy from the exhaust air is used by recirculating a portion of the exhaust air and mixing it with the intake air before the air is introduced into the fabric drying chamber. The system also provides for sensors that detect the temperature and/or humidity of the exhaust and the intake air.
