Abstract

Methods for operating appliances, as well as appliances such as cooktop appliances, are provided. A method includes locking the appliance such that user inputs to a user interface assembly of the appliance are prevented from altering operation of the appliance. The method further includes activating an indicator light when the appliance is locked, and deactivating the indicator light after a predetermined time period from activation of the indicator light when the appliance is locked.

Claims (43)

1. A method for operating an appliance, the method comprising: locking the appliance such that user inputs to a user interface assembly of the appliance are prevented from altering operation of the appliance;

activating an indicator light when the appliance is locked; and

deactivating the indicator light after a predetermined time period from activation of the indicator light, the step of deactivating occurring while continuing the step of locking the appliance such that user inputs to the user interface assembly are prevented from altering operation of the appliance; and

wherein the method further comprises

reactivating the indicator light at a predetermined time interval after deactivation, the step of reactivating occurring while continuing the step of locking the appliance such that user inputs to the user interface assembly are prevented from altering operation of the appliance, each reactivation occurring for a predetermined time period; or

reactivating the indicator light for a predetermined time period when a user input to the user interface assembly is detected after deactivation, the step of reactivating occurring while continuing the step of locking the appliance such that user inputs to the user interface assembly are prevented from altering operation of the appliance.

2. The method of claim 1 , further comprising:

3. The method of claim 1 , further comprising:

4. The method of claim 1 , further comprising:

reactivating the indicator light for a predetermined time period when power to the appliance is restored after a loss of power to the appliance.

5. The method of claim 1 , further comprising:

unlocking the appliance such that user inputs to the user interface assembly are permitted to alter operation of the appliance.

6. The method of claim 5 , wherein unlocking of the appliance is based on a user input to the user interface assembly.

7. The method of claim 1 , wherein locking of the appliance is based on a user input to the user interface assembly.

8. The method of claim 1 , wherein locking of the appliance occurs automatically after a predetermined time period from detection of an inactive state of the appliance.

9. The method of claim 1 , wherein locking of the appliance occurs automatically when power to the appliance is restored after a loss of power to the appliance.

10. The method of claim 1 , wherein the user interface assembly comprises a touch screen.

11. The method of claim 1 , wherein the appliance is a cooktop appliance.

12. A cooktop appliance,

comprising: a cooking panel comprising a cooking zone;

a heating element positioned adjacent the cooking zone for heating a cooking utensil disposed on the cooking zone;

a user interface assembly; and

a controller in communication with the user interface assembly and the heating element, the controller configured for:

locking the appliance such that user inputs to a user interface assembly of the appliance are prevented from altering operation of the appliance;

activating an indicator light when the appliance is locked; and

wherein the controller is further configured for

13. The cooktop appliance of claim 12 , wherein the controller is further configured for:

14. The cooktop appliance of claim 12 , wherein the controller is further configured for:

15. The cooktop appliance of claim 12 , wherein the controller is further configured for

reactivating the indicator light for a predetermined time period when power to the appliance is restored after a loss of power to the appliance.

16. The cooktop appliance of claim 12 , wherein the controller is further configured for:

unlocking the appliance such that user inputs to the user interface assembly are permitted to alter operation of the appliance.

17. The cooktop appliance of claim 12 , wherein locking of the appliance is based on a user input to the user interface assembly.

18. The cooktop appliance of claim 12 , wherein locking of the appliance occurs automatically after a predetermined time period from detection of an inactive state of the appliance.

19. The cooktop appliance of claim 12 , wherein locking of the appliance occurs automatically when power to the appliance is restored after a loss of power to the appliance.

20. The cooktop appliance of claim 12 , wherein the user interface assembly comprises a touch screen.
