  • Patent number: 5791890
    Abstract: A gas oven having an electronic controller for directly controlling the gas valve and burner ignition. The controller opens the gas valve and activates the ignitor whenever oven heating is required and then determines whether ignition has occurred, detected by an indicator of ignition, often a conventional oven thermostat, a thermocouple, a resistance temperature device (RTD), or other type of temperature sensor. Positive proof of ignition is given by determining whether the detected temperature is increasing at a particular rate. The gas valve is closed if ignition does not occur within a predetermined time, preferably about 10-15 seconds. Re-ignition may be attempted after a sufficient delay. The controller also closes the gas valve whenever the oven temperature is decreasing at a predetermined rate or is increasing at less than a predetermined rate.

  • Patent number: 5361749
    Abstract: A convection oven is given a lower profile so that two ovens may be stacked without exceeding a height so that the uppermost of the stacked ovens may be comfortably reached by a relatively short person. Also, the oven requires less floor space for installation and operation. The height of the oven is reduced by placing inshot burners at an inlet to the oven. Heretofore, the burners were placed under the oven, which increased the space which must be provided to enclose the burner, and therefore the overall height of the burner. The height of the oven is reduced by allowing the flue gas flow from front to rear before entering the cooking cavity. Heretofore, the flue gas flowed from under the cooking cavity to the sides and up towards the top of the cooking cavity. From there, it traveled to the top of the cooking cavity before entering the cooking cavity itself. Cool ambient air is blown over oven controls in order to cool them before the air is heated by the burners.
