Abstract
A method of operating an oven appliance includes obtaining a temperature set point, determining, based on the temperature set point, an electric heating temperature range and a gas undershoot temperature limit, the gas undershoot limit being below the electric heating temperature range, determining that a chamber temperature of the oven appliance has dropped to the gas undershoot temperature limit, and operating a gas heat source to maintain the chamber temperature above the gas undershoot temperature limit.
Claims18
A method of operating an oven appliance, the oven appliance comprising a cooking chamber, a gas heat source, and an electric heat source, the method comprising:
- obtaining a temperature set point via a user input;
- determining, using one or more computer processing units and based on the temperature set point, an electric heating temperature range and a gas undershoot temperature limit, the gas undershoot limit being below the electric heating temperature range, wherein the temperature set point is within the electric heating temperature range;
- activating the gas heat source and the electric heat source to reach the temperature set point;
- deactivating the gas heat source and cycling the electric heat source between an active state and an inactive state upon reaching the temperature set point;
- determining, using the one or more computer processing units, that a chamber temperature has dropped to the gas undershoot temperature limit;
- and
- operating the gas heat source to maintain the chamber temperature above the gas undershoot temperature limit, wherein the gas heat source is cycled between an active state and an inactive state while the electric heat source is maintained in an active state.
An oven appliance, comprising:
- a cabinet defining a cooking chamber;
- an electric heat source provided within the cooking chamber;
- a gas heat source provided within the cooking chamber;
- a temperature sensor provided within the cooking chamber and configured to sense a temperature of the cooking chamber;
- and
- a controller operably connected to the electric heat source, the gas heat source, and the temperature sensor, wherein the controller is configured to execute an operation comprising:
- obtaining a temperature set point;
- determining, based on the temperature set point, an electric heating temperature range and a gas undershoot temperature limit, the gas undershoot limit being below the electric heating temperature range;
- performing a first heating operation comprising operating each of the electric heat source and the gas heat source;
- deactivating the gas heat source and cycling the electric heat source between an activated state and a deactivated state when a chamber temperature has reached the temperature set point;
- determining that the chamber temperature has dropped to the gas undershoot temperature limit;
- and
- operating the gas heat source to maintain the chamber temperature above the gas undershoot temperature limit.
