  • Patent number: 5877477
    Abstract: An oven with high power radiant cooking elements which are capable of operating at different intensities is disclosed for cooking food quickly with infrared radiation. The conduction of this infrared radiant energy varies substantially from food to food. Accordingly, the user of the oven must develop a unique data base or recipe for each food. A recipe consists of a number of stages each of which defines the output intensity of each cooking element for a period of time. A method is disclosed for the real time development of a recipe by varying the intensity of the cooking elements during the cooking cycle, optimizing the developed recipe to reduce the number of stages, storing the optimized recipe in memory and retrieving the optimized stored recipe for future use.

  • Patent number: 4585925
    Abstract: A system to control and regulate heat output during the heat-up phase of a pressure cooker heated by a heating element which can be turned on and off by means of a control circuit. The heat-up phase is adjusted, depending on the rate of temperature increase before it reaches the boiling temperature, and is controlled by a different program after the boiling temperature is reached, which determines rates of further temperature increases and also the temperature differentials between a preset cooking temperature and the current cooking temperature. Using this apparatus, the cooking temperature can be reached as quickly as possible, regardless of the characteristics of the heating phase, dependent upon the type and amount of cooking material in the pressure cooker. Energy utilization efficiency can be increased and the preset cooking temperature not exceeded.

  • Patent number: 4454803
    Abstract: This drop-down toaster has a bread support and a door at the bottom of each toasting compartment. The door has a series of vent holes for air convection which produces improved uniformity in the toast. The door and bread support are held closed by rollers on solenoid-controlled sliding bars. The rollers allow the door to swing open before the bread support is released, and they return the door and bread support to their normal condition automatically by a cam action. The bread support is cammed upwardly before release to dislodge bread from the toasting compartment guide wires. An electronic timing circuit is located in a base underneath and spaced vertically from the toasting section so that it is not affected by heat from the toasting section. The timing circuit is compensated in accordance with previous use rather than by sensing the temperature of the toasting compartment.

  • Patent number: 4345513
    Abstract: A toaster for toasting a slice of bread comprises a casing in which a reciprocable carriage is located and is movable towards and away from an aperture defined by the casing through which aperture a slice of bread when mounted on the carriage can pass. A pair of enclosed electric bar heating elements is disposed within the casing respectively adjacent opposed side edges of the casing defining the aperture. A motor arrangement is provided for the carriage which can thereby be driven from a first position remote from the aperture into a second position at a predetermined speed. In this way a slice of bread mounted on the carriage can be made to pass between the elements to toast both sides of the slice progressively as the slice passes out of the casing through the aperture. The degree of toasting is determined by the speed of movement of the carriage.
