Abstract

A cooking apparatus includes a control circuit configured to operate an electronic lock on demand in response to user input provided to a user interface. The electronic lock may be operable regardless of whether the oven is active, and cooking operations may be started, stopped or modified even when the electronic lock is engaged.

Claims (44)

1. A cooking apparatus, comprising:

a housing;

an oven cavity disposed within the housing;

one or more cooking elements configured to beat the oven cavity;

a door coupled to the housing, wherein the door is movable from a closed position to an open position to provide external access to the oven cavity;

an electronic lock configured to selectively lock the door in the closed position;

a user interface configured to receive user input; and

a control circuit coupled to the electronic lock and the user interface, wherein the control circuit:

receives, from the user interface, first on demand lock user input to engage or disengage the electronic lock on demand while the oven is active;

selectively engages or disengages the electronic lock in response to the first on demand lock user input and while the oven is active;

receives, from the user interface, second on demand lock user input to engage or disengage the electronic lock on demand while the oven is inactive;

selectively engages or disengages the electronic lock in response to the second on demand lock user input and while the oven is inactive;

receives, from the user interface and while the electronic lock is engaged, cooking user input to start or stop an oven cooking operation; and

starts or stops the oven cooking operation while the electronic lock is engaged in response to the cooking user input.

2. The cooking apparatus of claim 1 , further comprising a cooktop, wherein the control circuit engages or disengages the electronic lock in response to the first and second on demand lock user input irrespective of whether the cooktop is currently active, wherein the cooking user input is first cooking user input, and wherein the control circuit starts and/or stops a cooktop cooking operation in response to second cooking user input while the electronic lock is engaged.

3. The cooking apparatus of claim 1 , wherein an actuator of the electronic lock is inaccessible to the user.

4. The cooking apparatus of claim 1 , wherein each of the first and second on demand lock user input includes simultaneous activation of multiple user controls of the user interface.

5. The cooking apparatus of claim 1 , wherein each of the first and second on demand lock user input includes activation of a user control of the user interface for a preset amount of time.

6. The cooking apparatus of claim 1 , wherein the control circuit further generates an alert after engaging or disengaging the electronic lock.

7. The cooking apparatus of claim 1 , wherein the control circuit further modifies the oven cooking operation in response to the cooking user input received while the electronic lock is engaged.

8. The cooking apparatus of claim 7 , wherein the cooking user input that modifies the oven cooking operation switches a cooking mode used for the oven cooking operation.

9. The cooking apparatus of claim 7 , wherein the cooking user input that modifies the oven cooking operation increases or decreases a temperature setpoint.

10. The cooking apparatus of claim 1 , wherein the control circuit starts, modifies, or stops a second oven cooking operation in response to the electronic lock engaging.

11. A method of operating a cooking apparatus of a type including a housing, an oven cavity disposed within the housing, one or more cooking elements configured to heat the oven cavity, a door coupled to the housing and movable from a closed position to an open position to provide external access to the oven cavity, an electronic lock configured to selectively lock the door in the closed position, a user interface configured to receive user input, and a control circuit, the method comprising:

receiving, from the user interface, first on demand lock user input to engage or disengage the electronic lock on demand while the oven is active;

selectively engaging or disengaging the electronic lock with the control circuit in response to the first on demand lock user input and while the oven is active;

receiving, from the user interface, second on demand lock user input to engage or disengage the electronic lock on demand while the oven is inactive;

selectively engaging or disengaging the electronic lock with the control circuit in response to the second on demand lock user input and while the oven is inactive;

receiving, from the user interface and while the electronic lock is engaged, cooking user input to start or stop an oven cooking operation; and

starting of stopping the oven cooking operation with the control circuit while the electronic lock is engaged in response to the cooking user input.

12. The method of claim 11 , further comprising:

determining, in response to receiving, from the user interface, the first on demand lock user input to engage or disengage the electronic lock on demand, whether the electronic lock has a delay, and in response to determining a delay exists, waiting the amount of time for the delay to expire before operating the electronic lock.

13. The method of claim 11 , further comprising:

determining, in response to selectively engaging or disengaging the electronic lock with the control circuit in response to the first on demand lock user input, whether to adjust the oven settings, and in response to determining to adjust the oven settings, adjusting the oven settings.

14. The method of claim 11 , further comprising:

determining, in response to selectively engaging or disengaging the electronic lock, whether an alert should be generated, and in response to determining that the alert should be generated, generating the alert.

15. The method of claim 11 , wherein the first on demand lock user input is a simultaneous activation of multiple user controls of the user interface.

16. The method of claim 11 , wherein the first on demand lock user input is an activation of a user control of the user interface for a preset amount of time.

17. The method of claim 11 , further comprising:

modifying, in response to receiving second cooking user input to modify the oven cooking operation, the oven cooking operation while the electronic lock is engaged.

18. The method of claim 17 , wherein the second cooking user input switches a cooking mode used for the oven cooking operation.

19. The method of claim 17 , wherein the second cooking user input increases or decreases a temperature setpoint.

20. The method of claim 11 , further comprising:

starting, modifying, or stopping, in response to selectively engaging or disengaging the electronic lock, a second oven cooking operation.
