Abstract

An oven for performing a rotisserie cooking operation includes an oven cavity having a door for selectively accessing the oven cavity, at least one heating element for heating the oven cavity and a rotisserie arm adapted to support a food product within the oven cavity. A motor is operatively coupled to the rotisserie arm for rotating the rotisserie arm and a food product. The oven also includes a control interface having a rotisserie cooking mode input and a control system for controlling the rotisserie motor and the heating element. In addition to other functions, the control system automatically causes the rotisserie motor to cycle on and off to allow for intermittent rotation of the food product supported on the rotisserie arm when the oven door is opened.

First claim

We claim:

1. A method for operating an oven having an oven cavity, at least one heating element for heating the oven cavity, a door movable between open and closed positions for selectively accessing the oven cavity, a rotisserie arm adapted to support a food product in the oven cavity, a motor operatively connected to rotate the rotisserie arm and a control unit, the method comprising:
upon selecting a rotisserie cooking mode of operation for the oven, activating the motor to rotate the rotisserie arm supporting a food product in the oven cavity, while operating the heating element to heat the oven cavity, with the door in the closed position;
establishing a cooking phase when the door is shifted to the closed position;
in response to the door being shifted to the open position, the control unit automatically cycles the motor on and off to cause intermittent rotation of the food product supported on the rotisserie arm while the door is open; and
altering operation of the rotisserie arm supporting the food product, from when the door is in the open position, during the cooking phase, wherein the heating element is activated when the motor is stopped during a portion of the cooking phase.

2. The method of claim 1 , wherein cycling the motor on and off provides for an intermittent 360 degree rotation of the food product supported on the rotisserie arm.

3. The method of claim 2 , wherein the intermittent 360 degree rotation of the food product occurs in 20-30 seconds.

4. The method of claim 1 , further comprising: controlling rotation of the rotisserie arm based on a preset timing sequence.

5. The method of claim 1 , wherein said heating element and said motor are cycled simultaneously during the cooking phase with the door in the closed position.

6. The method of claim 1 , further comprising:
sensing a temperature within the oven cavity during the cooking phase; and
controlling rotation of the rotisserie arm based on the sensed temperature.

7. The method of claim 1 , wherein the rotisserie arm is continuously rotated during the cooking phase with the door in the closed position.

8. A method for operating an oven, including an oven cavity, at least one heating element for heating the oven cavity, a door movable between open and closed positions for selectively accessing the oven cavity, a rotisserie arm adapted to support a food product in the oven cavity, a motor operatively connected to rotate the rotisserie arm and a control unit, in a rotisserie cooking mode of operation, the method comprising:
establishing a cooking phase when the door is shifted to the closed position;
when the door is in the closed position, activating, through the control unit, both the motor to rotate the rotisserie arm supporting a food product in the oven cavity and the heating element to heat the oven cavity;
when the door is in the open position, automatically cycling, through the control unit, the motor on and off to cause intermittent rotation of the food product supported on the rotisserie arm; and
altering operation of the rotisserie arm supporting the food product, from when the door is in the open position, during the cooking phase, wherein the heating element is activated when the motor is stopped during a portion of the cooking phase.

9. The method of claim 8 , further comprising: when the door is in the open position, deactivating, through the control unit, the heating element.
