Abstract
An oven range appliance is provided with features for locking out one or more cooktop elements of the oven range to boost preheat performance and thereby decrease the time required to preheat the cooking chamber of the oven range. A method for operating an oven range appliance also is provided. The method includes features for locking out one or more cooktop elements of the oven range to boost preheat performance and thereby decrease the time required to preheat the cooking chamber of the oven range.
Claims19
A method for operating an oven range appliance, the oven range appliance including a cooking chamber configured for receipt of food items for cooking, the oven range appliance also including a cooktop having one or more cooktop elements for heating or cooking food items, the method comprising the steps of:
- establishing a cooking chamber temperature set point Tpre for the cooking chamber;
- activating a heating element of the cooking chamber;
- determining whether a boost preheat mode of the cooking chamber has been chosen and, if so, then
- activating one or more lockout elements to lockout one or more of the cooktop elements;
- activating an additional heating element of the cooking chamber;
- sensing whether the temperature in the cooking chamber has reached at least Tpre and, if so, then
- activating the one or more lockout elements to unlock to the one or more locked out cooktop elements, and
- initiating a cooking cycle of the cooking chamber.
A method for operating an oven range appliance, the oven range appliance including a cooking chamber configured for receipt of food items for cooking, the oven range appliance also including a cooktop having one or more cooktop elements for heating or cooking food items, the method comprising the steps of:
- establishing a cooking chamber temperature set point Tpre for the cooking chamber;
- activating a heating element of the cooking chamber;
- determining whether a boost preheat mode of the cooking chamber has been chosen and, if so, then
- activating one or more lockout elements to lockout one or more of the cooktop elements;
- counting a time tlock;
- activating an additional heating element of the cooking chamber;
- determining whether the time tlock has reached at least a threshold time tthr and, if so, then
- activating the one or more lockout element to unlock to the one or more locked out cooktop elements.
An oven range appliance, comprising:
- a cabinet defining a cooking chamber configured for receipt of food items for cooking, the cooking chamber comprising a plurality of heating elements configured to heat the cooking chamber;
- a cooktop having one or more cooktop elements configured for heating or cooking food items;
- one or more lockout elements configured to lock out the one or more cooktop elements from a power supply;
- and
- a controller in operative communication with the heating elements of the cooking chamber, the one or more cooktop elements, and the one or more lockout elements, the controller configured for
- establishing a cooking chamber temperature set point Tpre for the cooking chamber;
- activating one of the plurality of heating elements;
- determining whether a boost preheat mode of the cooking chamber has been chosen and, if so, then
- activating one or more of the lockout elements to lockout one or more of the cooktop elements;
- activating an additional heating element;
- sensing whether the temperature in the cooking chamber has reached at least Tpre and, if so, then
- activating the one or more lockout elements to unlock to the one or more locked out cooktop elements, and
- initiating a cooking cycle of the cooking chamber.
