  • Patent number: 8440948
    Abstract: A heating cooker includes a cooking chamber accommodating an object to be cooked, a hot air generator and a blower. Hot air generated by the generator impinges as a high-speed impinging jet on the object from a nozzle hole located in a ceiling plate. The hot air having impinged on the object is drawn our through hot-air suction openings located in lower parts of right and left sidewalls of the chamber by the blower. A shelf plate is located in the chamber so that the object is placed on it. The shelf plate has openings on right and left sides. Hot air is caused to impinge on the object through the nozzle hole. The shelf has a convex portion formed on a face on which the object is to be placed which supports the object from below.

    Abstract: A susceptor assembly includes a generally planar susceptor having an electric field director structure mechanically connected thereto. The field director structure includes at least one, but more preferably, a plurality of two or more vanes mechanically connected to the susceptor. Each vane has a surface at least a portion of which is electrically conductive. The vane(s) are most preferably disposed substantially orthogonal to the planar susceptor. The connection may be either a fixed or a flexible articulating connection. In use, such as in the presence of a standing electromagnetic wave generated within a microwave oven, only an attenuated electric field component of the electromagnetic wave exists in a plane tangent to the surface of the vane in the vicinity of the conductive portion of the vane.

    Abstract: A combination convection/microwave oven in which a food product is cooked by microwave energy from a source thereof and by a heated airflow provided by a thermal energy source and a blower. The food product is located in the near field of the microwave energy. The oven includes a controller that operates the thermal energy source and/or the blower according to temperature and or time to improve cooking results. The cooking procedure includes a soak interval during which the thermal energy source, the blower and/or the microwave energy source is turned off, whereby the temperature of the food product is permitted to equilibrate and thereby provide more uniform cooking. The food product may be located directly on the rack or in a microwave transparent or reflective container.

  • Patent number: 6255637
    Abstract: A stacking arrangement for simultaneously stacking plural food filled plates and beverage containers together for use in microwaves and refrigerators. Hollow rings with outwardly sloping sides each having side oval through-holes and upper edge grooves are placed on food filled plates so that the plates can be stacked on top of each hollow ring. A cover with outwardly sloping sides has a handle with a lid and through-hole adjacent to the handle covers the top food filled plate in the stack. The stack can be placed in a microwave, heating oven, refrigerator or freezer. The through-holes in the rings and the cover act as vents to allow heat to be evenly dispersed about the food and to allow the food to be more evenly cooked when being microwaved. The cover and rings can be made of microwaveable plastic such as polypropylene. When not being used the rings can together be inserted into the cover for storage.

  • Patent number: 6060700
    Abstract: A microwave oven adapted for use within a motor vehicle dashboard area. The microwave oven has a removable storage cassette, and slidable platforms for securing and serving containers of beverages and foods. A motor vehicle featuring a microwave oven in which food may be heated by a microwave-generating magnetron powered directly or indirectly by the vehicle's battery and/or alternator. The space required for the microwave oven is provided by elimination of the major dashboard storage compartment, i.e., the glove compartment. The microwave oven door opens to a horizontal position to provide a securing and serving surface for hot beverages and food. The microwave oven accommodates a removable storage cassette for glove compartment items. The storage cassette must be removed as one condition, and the door of the microwave oven must be closed as a second condition for the magnetron to receive electrical power.

  • Patent number: 6002120
    Abstract: An electric oven includes a microwave energy source (2), a waveguide (3) with an output section that terminates in a cooking enclosure defined by a base wall (4), a top wall (5), a sole wall (6) and two side walls (7, 8), and a rotary device (R) inside the cooking enclosure, for receiving food products to be cooked, and rotated by control elements (23) external to the cooking enclosure. The rotary device (R) has two or more rotary plates (9, 10), an upper (9) and a lower (10) plate, removably mounted in the cooking enclosure, one above the other and spaced from each other by a distance d, and the output section of the waveguide (3) is adapted to allow a suitable distribution of the waves on the two plates (9, 10).

  • Patent number: 5938968
    Abstract: The present invention relates to a retractable shelf assembly which may be easily mounted within a microwave oven cooking chamber. A pair of elongated substantially rectangular outer track members having an open end are mounted to the bottom of the microwave oven interior adjacent opposing sides. A pair of inner track members are longitudinally and slidably received within the outer track members and telescopable therefrom. A shelf with a pair of open sided channels on opposing edges is attached at an end to the inner track members and slidably engages the outer track members. The telescoping track and channel assembly allows the shelf to be slid horizontally into or out of a microwave oven as desired. A telescoping brace component vertically extends from the upper surface of the shelf component to engage the interior of the microwave thereby preventing the tray from completely sliding off the telescoping track mechanism.

  • Patent number: 5796082
    Abstract: A microwave oven includes a cooking chamber in which a plurality of removable horizontal partition plates are mounted to divide the cooking chamber into vertically adjacent compartments. A tray is rotatably mounted on each partition plate. A drive shaft carries vertically spaced drive elements, such as friction wheels or gears, which are engageable with respective trays. An electric motor drives the drive shaft to rotate the trays. The trays become disengaged from the drive elements in response to being removed from the cooking chamber. An additional driven tray is mounted on a floor of the cooking chamber.

  • Patent number: 5695672
    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.
