  • Publication number: 20210293414
    Abstract: A convection cooking oven includes a cooking cavity for receiving food product to be cooked, a door movable between an open condition and a closed condition relative to the cooking cavity and a heater for generating heat. A fan system is provided for moving heated air within the cooking cavity, the fan system operable in both a first mode in which air is moved at a first rate, and a second mode in which either (i) air is moved at a second rate, which is lower than the first rate, or (ii) air is not moved by the fan system. A fan system override control is configured such that, when the fan system is operating in the first mode, the fan system is automatically switched to operate in the second mode based upon occurrence of a first predefined oven condition.

  • Patent number: 9618211
    Abstract: A cooking oven includes a housing defining an internal cooking cavity with an opening. A door assembly includes an inner panel framing an inner glass pane, and an outer panel framing an outer glass pane. A pivot arrangement pivotably mounts the door assembly to the housing. The pivot arrangement includes at least one pivot part located on the door assembly and at least one pivot part located on the housing. The pivot part of the door assembly is separable from the pivot part of the housing via vertically upward movement of the door assembly and upon separation of the pivot part of the door assembly from the pivot part of the housing the door becomes completely removed from the housing to enable the door assembly to be taken to a washing station for cleaning.
