  • Patent number: 6198077
    Abstract: The present invention relates to a temperature compensated timer for a heating appliance that heats a food item during a heating cycle. The timer includes a coil having first and second terminals and presenting a resistance between the terminals that is a function of temperature changes of the coil. A timing circuit is coupled to the first and second terminals of the coil. The timing circuit operates to drive a current through the coil to maintain a heating cycle and to generate a delay signal a delay time after the heating cycle is initiated. The delay time has a value that is a function of the resistance of the coil. The delay signal is operable to remove the current from the coil to terminate the heating cycle.

  • Patent number: 6198078
    Abstract: A toaster broiler oven with an NTC temperature probe located within the oven chamber and a controller that controls the heater of the oven in a thermostat operation for non-toasting modes and in a variable toasting interval length operation in the toasting mode. When the toaster start switch is activated in the toast mode, the controller determines if the oven chamber temperature is greater than a predetermined temperature, such as room temperature. If not, a first toast interval is selected. If so, a second shorter toast interval is selected. The length of the second interval is chosen so that the toaster oven consistently produces toast of a selected color from one toast cycle to the next, regardless of the elapsed time between consecutive toast cycles.

  • Patent number: 5938961
    Abstract: A controller for controlling the cooking of food within a cooking apparatus. The controller is comprised of a temperature sensor input for receiving an output of a temperature sensor and a system for initiating a cook of a food product based upon a set cook temperature and a set cook time. Plural indications of incremental energy that is absorbed by the food product during the cook are determined, wherein each of the plural indications of incremental energy is based upon a difference between a temperature determined at the temperature sensor input and a desired internal temperature of the food product. The end of the cook is established when the total of the plural indications of incremental energy is one of equal to and greater than an ideal energy to prepare the food product based upon the set cook time and the cook temperature.

  • Patent number: 5901639
    Abstract: A temperature sensitive timing assembly for a toaster appliance includes a single bimetallic element having a first portion connected to a support bracket, which in turn is mounted on a mounting bracket for pivotal movement relative to the mounting bracket. A spring is positioned between the mounting bracket and the support bracket to bias the support bracket toward the mounting bracket. A stop is mounted to the mounting bracket which locks the support bracket in a fixed position when actuated by the toaster carriage assembly at the beginning of a toasting cycle. The bimetallic element has a second portion which operatively activates the toaster lock release assembly at the end of a toasting cycle. The bimetallic element also has a third portion which operatively allows the support bracket to reposition at the end of a toasting cycle so as to provide virtually immediate initiation of the next toasting cycle providing substantially the same toast color as the previous toasting cycle.

  • 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.
