ABSTRACT:
An oven is provided with structure which maintains a door, adapted to extend across and seal against an open frontal portion of a heating cavity of the oven, slightly ajar from a fully closed position so as to just break a seal between the door and the oven cavity in order to enable moisture to escape the oven cavity when utilizing the oven for dehydrating food products. For this purpose, the oven incorporates a spacer element that is movable between a de-activated position, wherein the oven can be used in a conventional manner, and an activated position for use in a drying mode of operation. In a preferred embodiment of the invention, a pivotally mounted spacer element is positioned between the door and a cabinet portion of the oven for movement between the de-activated and activated positions. In this preferred embodiment, the spacer element is automatically movable from the activated to the de-activated position due to gravity upon the opening of the door. The oven also includes a control system for establishing the drying mode of operation and inputting a desired dehydration temperature. In addition, the control system includes an arrangement for overriding the desired dehydration temperature if the set temperature is outside a predetermined temperature range by establishing a predetermined default temperature.
