Abstract
A cooking appliance and method may generate one or more audible and/or visual indications to a user of various gas burner states during the operation of a gas burner, including, for example, states that are associated with different types of ignition operations, such as initial ignition operations, programmed re-ignition operations and/or flame loss re-ignition operations and/or states that are associated with ignition operations, normal operating conditions, and/or failure conditions.
Claims20
A cooking appliance, comprising:
- a cooktop including a gas burner;
- an igniter disposed adjacent to the gas burner to ignite the gas burner;
- a flame detector positioned to sense a flame emitted by the gas burner;
- an electromechanical gas valve configured to regulate gas flow to the gas burner;
- a burner control electronically coupled to the gas valve to vary the gas flow to the gas burner;
- a visual indicator device positioned proximate the burner control;
- and
- a control circuit coupled to the indicator, the igniter, the electromechanical gas valve and the flame detector and configured to control the electromechanical valve to regulate gas flow to the gas burner and activate the igniter when gas is flowing to the gas burner, the control circuit further configured to detect a flame loss using the flame detector and control the visual indicator device to distinguish between first, second, third, fourth, and fifth states of the gas burner;
- wherein when the gas burner is in the first state, the control circuit controls the visual indicator device to indicate that the gas burner is performing an initial ignition operation;
- wherein when the gas burner is in the second state, the control circuit controls the visual indicator device to indicate that the gas burner is in a normal operating condition;
- wherein when the gas burner is in the third state, the control circuit controls the visual indicator device to indicate that the gas burner is performing a flame loss re-ignition operation;
- wherein when the gas burner is in the fourth state, the control circuit controls the visual indicator device to indicate that the gas burner is performing a program re-ignition operation;
- and
- wherein when the gas burner is in the fifth state, the control circuit controls the visual indicator device to indicate that the gas burner has a failure condition due to an inability to ignite the gas burner after attempting an initial ignition, flame loss re-ignition or program re-ignition operation.

A cooking appliance, comprising:
- a gas burner;
- an igniter disposed adjacent to the gas burner to ignite the gas burner;
- a gas valve configured to regulate gas flow to the gas burner;
- a burner control coupled to the gas valve to vary the gas flow to the gas burner;
- and
- a control circuit coupled to the igniter and configured to activate the igniter when gas is flowing to the gas burner, and the control circuit further configured to generate a first indication to a user in response to performing a first ignition operation of a first ignition type and to generate a second indication to the user in response to performing a second ignition operation of a second ignition type, wherein the first and second indications are different from one another to distinguish between the first and second ignition types.
