COOK TOP ASSEMBLY WITH DUAL POWER SOURCE

摘要

The invention relates to a gas cook top assembly that is capable of operating in off-grid applications where no electricity is available and that is also adaptable to operating in on-grid applications. The cook top is provided with a first control loop with a battery pack for powering the control valves for releasing gas to the gas burners and a spark ignition module for generating a spark to ignite the corresponding gas burner in an off-grid application. The cook top is also provided with second control loop for delivering power from an on-grid AC power source to the control valves and spark ignition module. The second control loop may operate independently of the first control loop or may be connected in parallel with the first control loop, the second control loop receiving AC power through an AC-to-DC converter.

主权项

1. A gas cook top assembly comprising:
a cooking surface having a plurality of gas burners for receiving a gas supply from a gas source; a spark ignition module for igniting each of said gas burners; individual control valves for selectively operating each of the plurality of gas burners; a spark ignition control circuit for receiving electrical power from one of a first power source and a second power source and delivering the electrical power to said individual control valves and said spark ignition module; a first control loop electrically connected to said spark ignition circuit for delivering electrical power from said first power source to said spark ignition circuit; a second control loop electrically connected to said spark ignition circuit for delivering electrical power from said second power source; wherein said first power source is a DC power source from a battery pack and said second power source is an AC-to-DC power source; and wherein said first control loop is isolated from said second control loop.
