Abstract

Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a one or more processors configured to detect an improper shutdown of a control system of the pellet grill. The one or more processors are further configured to generate a notification in response to the control system regaining power following detection of the improper shutdown, the notification indicating that the control system was improperly shutdown. The one or more processors are further configured to cause the notification to be presented at a user interface of the pellet grill.

First claim

What is claimed is:

1 . A pellet grill, comprising:
one or more processors configured to: detect an improper shutdown of a control system of the pellet grill; in response to the control system regaining power following detection of the improper shutdown, generate a notification indicating that the control system was improperly shutdown; and cause the notification to be presented at a user interface of the pellet grill.

2 . The pellet grill of claim 1 , wherein the one or more processors are configured to detect the improper shutdown by detecting an unexpected loss of power to the control system.

3 . The pellet grill of claim 1 , wherein the one or more processors are further configured to cause the notification to be wirelessly transmitted from the pellet grill to a device located remotely from the pellet grill.

4 . The pellet grill of claim 1 , wherein the one or more processors are further configured to initiate a diagnostic check of the control system in response to the control system regaining power following detection of the improper shutdown.

5 . The pellet grill of claim 4 , wherein the one or more processors are further configured to initiate a startup protocol of the control system following completion of the diagnostic check.

6 . The pellet grill of claim 1 , further comprising an auger and an auger motor operatively coupled to the auger, wherein the one or more processors are further configured to:
in response to the control system regaining power following detection of the improper shutdown, command the auger motor to repeatedly pulse the auger between a first direction of rotation and a second direction of rotation opposite the first direction; determine, based on the pulsed rotation of the auger, whether the auger is jammed; and in response to determining that the auger is jammed, initiate a protocol to clear the jam.

7 . The pellet grill of claim 6 , wherein the auger motor is a direct current (DC) powered electric motor.

8 . The pellet grill of claim 1 , further comprising a fan and a burn pot, wherein the one or more processors are further configured to command the fan to operate in a pulsed output mode in response to the control system regaining power following detection of the improper shutdown, the operation of the fan in the pulsed output mode to cause ash located in the burn pot to be removed from the burn pot.

9 . The pellet grill of claim 8 , wherein the fan is a direct current (DC) powered electric fan.

10 . A method, comprising:
detecting, via one or more processors of a pellet grill, an improper shutdown of a control system of the pellet grill; in response to the control system regaining power following detection of the improper shutdown, generating, via the one or more processors, a notification indicating that the control system was improperly shutdown; and presenting the notification at a user interface of the pellet grill.

11 . The method of claim 10 , wherein detecting the improper shutdown includes detecting an unexpected loss of power to the control system.

12 . The method of claim 10 , further comprising initiating, via the one or more processors, a diagnostic check of the control system in response to the control system regaining power following detection of the improper shutdown.

13 . The method of claim 12 , further comprising initiating, via the one or more processors, a startup protocol of the control system following completion of the diagnostic check.

14 . The method of claim 10 , further comprising:
in response to the control system regaining power following detection of the improper shutdown, commanding, via the one or more processors, an auger motor of the pellet grill operatively coupled to an auger of the pellet grill to repeatedly pulse the auger between a first direction of rotation and a second direction of rotation opposite the first direction; determining, via the one or more processors, based on the pulsed rotation of the auger, whether the auger is jammed; and in response to determining that the auger is jammed, initiating, via the one or more processors, a protocol to clear the jam.

15 . The method of claim 10 , further comprising commanding, via the one or more processors, a fan of the pellet grill to operate in a pulsed output mode in response to the control system regaining power following detection of the improper shutdown, the operation of the fan in the pulsed output mode to cause ash located in the burn pot to be removed from the burn pot.

16 . A non-transitory computer-readable storage medium comprising instructions that, when executed, cause one or more processors of a pellet grill to at least:
detect an improper shutdown of a control system of the pellet grill; in response to the control system regaining power following detection of the improper shutdown, generate a notification indicating that the control system was improperly shutdown; and cause the notification to be presented at a user interface of the pellet grill.

17 . The non-transitory computer-readable storage medium of claim 16 , wherein the instructions, when executed, cause the one or more processors to detect the improper shutdown by detecting an unexpected loss of power to the control system.

18 . The non-transitory computer-readable storage medium of claim 16 , wherein the instructions, when executed, cause the one or more processors to initiate a diagnostic check of the control system in response to the control system regaining power following detection of the improper shutdown.

19 . The non-transitory computer-readable storage medium of claim 16 , wherein the instructions, when executed, cause the one or more processors to:
in response to the control system regaining power following detection of the improper shutdown, command an auger motor of the pellet grill operatively coupled to an auger of the pellet grill to repeatedly pulse the auger between a first direction of rotation and a second direction of rotation opposite the first direction; determine, based on the pulsed rotation of the auger, whether the auger is jammed; and in response to determining that the auger is jammed, initiate a protocol to clear the jam.

20 . The non-transitory computer-readable storage medium of claim 16 , wherein the instructions, when executed, cause the one or more processors to command a fan of the pellet grill to operate in a pulsed output mode in response to the control system regaining power following detection of the improper shutdown, the operation of the fan in the pulsed output mode to cause ash located in the burn pot to be removed from the burn pot.
