Methods and systems for ignition of a smoke unit fuel source

1 . A system comprising:

at least one data processor; and

memory storing instructions, which when executed by the at least one data processor, cause the at least one data processor to perform operations comprising:

receiving data characterizing a plurality of measurements of a rate of energy supplied to an igniter of a smoke unit and of a temperature of a region proximate the igniter, each of the plurality of measurements acquired during a predetermined period of time during which the igniter is activated and during an initial ignition operating mode of the igniter;

determining, based on the received data, an average rate of energy supplied to the igniter during the predetermined period of time and an average temperature of the region proximate the igniter during the predetermined period of time;

determining, based on the determined average rate of energy supplied to the igniter and the determined average temperature of the region proximate the igniter, a maximum time of activation of the igniter when the igniter is operating in the initial ignition operating mode;

determining whether a total length of time during which the igniter is activated exceeds the maximum time of activation; and

causing the igniter to deactivate in response to determining that the total length of the time exceeds the determined maximum time of activation.

2 . The system of claim 1 , wherein the operations further comprise:

receiving second data characterizing an operating mode of the smoke unit, and

wherein the maximum time of activation is determined based on the received second data.

3 . The system of claim 1 , wherein the operations further comprise:

receiving third data characterizing a temperature of the air within a hollow cooking chamber in fluid communication with the smoke unit; and

determining, based on the received third data, whether the hollow cooking chamber is in a cold temperature state.

4 . The system of claim 3 , wherein the operations further comprise:

receiving fourth data characterizing a temperature of the region proximate the igniter; and wherein the determining of whether the smoke unit is in a cold temperature state includes:

determining whether a difference between the temperature of the region proximate the igniter and the temperature of the air within the hollow cooking chamber is less than or equal to a predetermined temperature difference threshold.

5 . The system of claim 3 , wherein the determining of whether the smoke unit is in a cold temperature state includes:

determining whether the temperature of the region proximate the igniter is less than a predetermined temperature threshold.

6 . The system of claim 3 , wherein the determining of whether the smoke unit is in a cold temperature state includes:

determining whether the temperature of the air within the hollow cooking chamber is less than the predetermined temperature threshold.

7 . The system of claim 3 , wherein the operations further comprise:

in response to determining that the smoke unit is in a cold temperature state, determining instructions for operating a fan in fluid communication with the smoke unit in a fan compensation mode; and

providing the instructions to a controller of the fan to cause the fan to operate in the fan compensation mode.

8 . A method comprising:

receiving data characterizing a plurality of measurements of a rate of energy supplied to an igniter of a smoke unit and of a temperature of a region proximate the igniter, each of the plurality of measurements acquired during a predetermined period of time during which the igniter is activated and during an initial ignition operating mode of the igniter;

determining, based on the received data, an average rate of energy supplied to the igniter during the predetermined period of time and an average temperature of the region proximate the igniter during the predetermined period of time;

determining, based on the determined average rate of energy supplied to the igniter and the determined average temperature of the region proximate the igniter, a maximum time of activation of the igniter when the igniter is operating in the initial ignition operating mode

determining whether a total length of time during which the igniter is activated exceeds the maximum time of activation; and

causing the igniter to deactivate in response to determining that the total length of the time exceeds the determined maximum time of activation.

9 . The method of claim 8 , further comprising:

receiving second data characterizing an operating mode of the smoke unit, and

wherein the maximum time of activation is determined based on the received second data.

10 . The method of claim 8 , further comprising:

receiving third data characterizing a temperature of the air within a hollow cooking chamber in fluid communication with the smoke unit; and

determining, based on the received third data, whether the smoke unit is in a cold temperature state.

11 . The method of claim 10 , wherein the operations further comprise:

receiving fourth data characterizing a temperature of the region proximate the igniter; and wherein the determining of whether the smoke unit is in a cold temperature state includes:

determining whether a difference between the temperature of the region proximate the igniter and the temperature of the air within the hollow cooking chamber is less than or equal to a predetermined temperature difference threshold.

12 . The method of claim 11 , wherein the determining of whether the smoke unit is in a cold temperature state includes:

determining whether the temperature of the region proximate the igniter is less than a predetermined temperature threshold.

13 . The method of claim 10 , wherein the determining of whether the smoke unit is in a cold temperature state includes:

determining whether the temperature of the air within the hollow cooking chamber is less than the predetermined temperature threshold.
