Adjusting preheating parameters for cooking appliances
A cooking appliance includes at least one heating element to selectively supply heat to a cookware item; and a controller operably connected with the at least one heating element, the controller configured to direct a heating operation. The heating operation includes a preheating phase and a cooking phase. The heating operation includes receiving a temperature setpoint for the cooking phase; determining at least one attribute for the at least one heating element for the preheating phase, the at least one attribute being based on the temperature setpoint; and initiating the preheating phase by directing the at least one heating element according to the at least one determined attribute.
1 . A cooking appliance defining a vertical direction, a lateral direction, and a transverse direction, the cooking appliance comprising:
at least one heating element to selectively supply heat to a cookware item; and
a controller operably connected with the at least one heating element, the controller configured to direct a heating operation comprising a preheating phase and a cooking phase, wherein directing the heating operation comprises:
receiving a temperature setpoint for the cooking phase;
determining a power level of the at least one heating element for the preheating phase based on the temperature setpoint, wherein determining the power level comprises retrieving the power level from a lookup table comprising a plurality of power levels; and
initiating the preheating phase by directing the at least one heating element according to the determined power level.
2 . The cooking appliance of claim 1 , wherein the at least one heating element comprises a plurality of heating elements, wherein the lookup table comprises a plurality of unique lookup tables, and wherein each of the plurality of heating elements is associated with a unique lookup table of the plurality of unique lookup tables.
3 . The cooking appliance of claim 1 , wherein determining the power level of the at least one heating element comprises:
performing one or more equations based on the temperature setpoint and two or more known power levels to interpolate the power level.
4 . The cooking appliance of claim 1 , wherein the at least one heating element is directed at the determined power level for a predetermined length of time, the predetermined length of time being a duration of the preheating phase.
5 . The cooking appliance of claim 1 , wherein the preheating phase comprises at least a first stage having a first duration and a second stage having a second duration and performed after the first stage.
6 . The cooking appliance of claim 5 , wherein the determined power level of the at least one heating element comprises:
a first determined power level for the first stage; and
a second determined power level for the second stage, the second determined power level being different from the first determined power level.
7 . The cooking appliance of claim 6 , wherein initiating the preheating phase comprises:
directing the at least one heating element at the first determined power level for the first duration; and
directing the at least one heating element at the second determined power level for the second duration.
8 . A method of operating a cooking appliance, the cooking appliance comprising at least one heating element, the method comprising:
receiving a temperature setpoint for a cooking operation, the cooking operation comprising a preheating phase and a cooking phase;
determining a power level of the at least one heating element for the preheating phase based on the temperature setpoint, wherein determining the power level comprises retrieving the power level from a lookup table comprising a plurality of power levels; and
initiating the preheating phase by directing the at least one heating element according to the determined power level.
9 . The method of claim 8 , wherein the at least one heating element comprises a plurality of heating elements, wherein the lookup table comprises a plurality of unique lookup tables, and wherein each of the plurality of heating elements is associated with a unique lookup table of the plurality of unique lookup tables.
10 . The method of claim 8 , wherein determining the power level of the at least one heating element comprises:
performing one or more equations based on the temperature setpoint and two or more known power levels to interpolate the power level.
11 . The method of claim 8 , wherein the at least one heating element is directed at the determined power level for a predetermined length of time, the predetermined length of time being a duration of the preheating phase.
12 . The method of claim 8 , wherein the preheating phase comprises at least a first stage having a first duration and a second stage having a second duration and performed after the first stage.
13 . The method of claim 12 , wherein the determined power level of the at least one heating element comprises:
a first determined power level for the first stage; and
a second determined power level for the second stage, the second determined power level being different from the first determined power level.
14 . The method of claim 13 , wherein initiating the preheating phase comprises:
directing the at least one heating element at the first determined power level for the first duration; and
directing the at least one heating element at the second determined power level for the second duration.
