Abstract

Claims (50)

1. A method comprising:

receiving first temperature data characterizing a temperature of air within an upper region of an interior chamber of a cooking device, the upper region being above a cooking surface, and second temperature data characterizing a temperature of air within a lower region of the interior chamber, the lower region being below the cooking surface;

determining, based on the received first and second temperature data, a ratio between an amount of heat to be supplied to the interior chamber by an upper heater and an amount of heat to be supplied to the interior chamber by a lower heater, the upper and lower heaters being disposed in the interior chamber at opposing surfaces of the interior chamber;

causing heat to be supplied to the interior chamber by at least one of the upper and lower heaters based on the determined ratio; and

adjusting an amount of heat supplied by at least one of the upper and lower heaters after a period of time, wherein the period of time is determined based on the determined ratio.

2. The method of claim 1 , further comprising receiving mode data characterizing a mode of cooking food, wherein the mode data includes a target temperature, and wherein the ratio is further determined based on the received mode data.

3. The method of claim 1 , the causing of the heat to be supplied to the interior chamber occurs when the cooking device is operating in a pre-heating state.

4. The method of claim 3 , further comprising adjusting the amount of the heat supplied to the interior chamber by the upper heater and the amount of the heat supplied to the interior chamber by the lower heater when the temperature of the air within the lower region of the interior chamber is less than a target temperature.

5. The method of claim 4 , further comprising:

receiving third temperature data characterizing a subsequent temperature of the air within the upper region of the interior chamber;

determining whether the subsequent temperature is greater than or equal to the target temperature; and

in response to determining that the subsequent temperature is greater than or equal to the target temperature, causing the upper heater and the lower heater to deactivate.

6. The method of claim 2 , wherein the method is carried out by a cooking system having a user interface, the method further comprising receiving, via the user interface, a user input characterizing a selection of the mode of cooking the food from a plurality of cooking modes.

7. The method of claim 6 , wherein the plurality of cooking modes comprise one or more predefined modes for cooking pizza and a custom mode configured for cooking a pizza in accordance with user-defined custom cooking parameters.

8. The method of claim 7 , wherein the period of time is further determined based on the mode data.

9. The method of claim 8 , further comprising:

comparing the temperature of air within the lower region to the target temperature;

determining whether the period of time has elapsed;

responsive to determining that the temperature of the air within the lower region is less than the target temperature and that the period of time has elapsed, causing the lower heater to deactivate and the upper heater to activate at a maximum power; and

responsive to determining that the temperature of the air within the lower region is greater than or equal to the target temperature, causing the lower heater to deactivate and the upper heater to activate at the maximum power.

10. The method of claim 1 , further comprising:

determining a lower heater energy value based on the determined ratio, the lower heater energy value characterizing a portion of available energy allocated to the lower heater and which is higher than a predetermined minimum lower heater power value;

determining a lower heating portion value based on the lower heater energy value, the lower heating portion value characterizing a portion of available energy allocated to the lower heater when a first temperature measured with a lower temperature sensor is below a first predetermined threshold temperature and a second temperature measured with an upper temperature sensor is below a second predetermined threshold temperature; and

wherein the period of time is determined based on the determined lower heating portion value.

11. A cooking device comprising:

an interior chamber having a cooking surface;

a first temperature sensor configured acquire first temperature data characterizing a temperature of air within an upper region of the interior chamber, the upper region being above the cooking surface;

a second temperature sensor configured acquire second temperature data characterizing a temperature of air within a lower region of the interior chamber, the lower region being below the cooking surface;

a first heater configured to provide heat to the upper region;

a second heater configured to provide heat to the lower region; and

a controller communicatively coupled to the first and second temperature sensors and the first and second heaters, the controller configured to perform operations comprising

receiving first temperature data characterizing a temperature of air within the upper region from the first temperature sensor and second temperature data characterizing a temperature of air within the lower region from the second temperature sensor,

determining, based on the received first and second temperature data, a ratio between an amount of heat to be supplied to the interior chamber,

causing heat to be supplied to the interior chamber by at least one of the first and second heaters based on the determined ratio, and

adjusting an amount of heat supplied by at least one of the first and second heaters after a period of time, wherein the period of time is determined based on the determined ratio.

12. The cooking device of claim 11 , wherein the controller is configured to perform operations further comprising receiving mode data characterizing a mode of cooking food, wherein the mode data includes a target temperature, and wherein the ratio is further determined based on the received mode data.

13. The cooking device of claim 11 , wherein the causing of the heat to be supplied to the interior chamber occurs when the cooking device is operating in a pre-heating state.

14. The cooking device of claim 13 , wherein the controller is configured to perform operations further comprising adjusting the amount of the heat supplied to the interior chamber by the first heater and the amount of the heat supplied to the interior chamber by the second heater when the temperature of the air within the lower region of the interior chamber is less than a target temperature.

15. The cooking device of claim 14 , wherein the controller is configured to perform operations further comprising:

receiving third temperature data characterizing a subsequent temperature of the air within the upper region of the interior chamber from the first temperature sensor;

determining whether the subsequent temperature is greater than or equal to the target temperature; and

in response to determining that the subsequent temperature is greater than or equal to the target temperature, causing the first heater and the second heater to deactivate.

16. The cooking device of claim 11 , further comprising a user interface, wherein the controller is configured to receive, via the user interface, a user input characterizing a selection of the mode of cooking the food from a plurality of cooking modes.

17. The cooking device of claim 16 , wherein the plurality of cooking modes comprise one or more predefined modes for cooking pizza and a custom mode configured for cooking a pizza in accordance with user-defined custom cooking parameters.
