  • Patent number: 10677472
    Abstract: A system and method for preheating a cooking chamber of an oven appliance is provided. The oven appliance may include one or more heating elements that operate according to a control algorithm that prevents the center oven temperature from exceeding a maximum desired temperature threshold. The control algorithm accounts for discrepancies between the measured oven temperature and the actual center oven temperature, particularly when preheating a cold oven. As a result, the control algorithm selectively operates one or more of the heating elements after the measured oven temperature is above the maximum desired temperature threshold. Preheating the cooking chamber in this manner will improve overall cooking performance.

  • Patent number: 7196291
    Abstract: An improved food oven apparatus and related methods for preparing food utilizing digitally controlled heating elements and a smoker unit. User-operable controls in communication with a digital controller allow for independent control of the heating elements and the smoker unit. One or more electric fans can be provided for reducing condensation from forming within a control unit of the food oven. A heating element connection assembly can also be provided for reducing stress exerted on the heating elements caused by the repeated expansion and contraction of the compartment. The food oven can also be provided with an air cleaning apparatus configured to perform a multi-stage cleaning process, thereby eliminating the need for a separate fixed hood system.
