Quick sear barbecue grill and components thereof

1. A grill comprising:

a firebox;

a quick sear burner positioned in the firebox;

a quick sear valve assembly adapted for fluid communication with the quick sear burner to provide gaseous fuel into the quick sear burner, the quick sear valve assembly comprising

a main valve for normal operation of the quick sear burner, and

a bypass valve for higher intensity heat output by the quick sear burner than the main valve;

a quick sear actuator to selectively actuate the bypass valve; and

a cooking surface adapted to be positioned above the quick sear burner and in or on the firebox.

2. The grill of claim 1 , wherein the quick sear valve assembly comprises

a first state in which gas is permitted to flow through the main valve into the quick sear burner but not permitted to flow through the bypass valve, and

a second state in which the bypass valve is actuated and gas is permitted to flow through the bypass valve into the quick sear burner, resulting in a higher heat output than the first state.

3. The grill of claim 2 , wherein in the second state, gas is permitted to flow through both the main valve and the bypass valve into the quick sear burner.

4. The grill of claim 2 , further comprising a control knob for controlling the quick sear valve assembly.

5. The grill of claim 4 , wherein the actuator comprises the control knob.

6. The grill of claim 5 , wherein the quick sear valve assembly can enter the second state only when the control knob has been placed on a high setting corresponding to substantially maximum gas flow through the main valve.

7. The grill of claim 5 , wherein:

gas flow through the main valve is controlled by rotating the control knob, and

gas flow through the bypass valve is actuated, and the quick sear valve assembly is placed in the second state, by pushing the control knob in a lateral direction.

8. The grill of claim 2 , wherein:

the actuator is configured such that actuation of the bypass valve requires an actuating act by a user; and

when the user halts the actuating act, gas no longer flows through the bypass valve.

9. The grill of claim 2 , further comprising a timer that measures the duration of time that the quick sear valve assembly has been in the second state.

10. The grill of claim 9 , further comprising an indicator, wherein the indicator provides a visual indication of the duration of time that the quick sear valve assembly has been in the second state.

11. The grill of claim 2 , wherein the actuator is configured such that actuation of the bypass valve automatically ceases after a predetermined duration of time.

12. The grill of claim 11 , further comprising:

an electromagnet proximate the actuator,

a timer, and

a power source for selectively energizing the electromagnet and the timer,

wherein movement of the actuator in a predetermined direction permits gas flow through the bypass valve, causes the actuator to come in magnetic contact with the electromagnet, causes power to be supplied for energizing the electromagnet, and activates the timer, and

further wherein the timer enables the electromagnet to remain sufficiently energized to hold the actuator in place to allow continued gas flow through the bypass valve for the predetermined duration of time.

13. The grill of claim 2 , wherein the quick sear valve assembly is configured such that:

in the first state, the quick sear valve assembly has a first maximum gas flow rate corresponding to a quick sear burner heat output of approximately 10,000 to 12,000 BTUs, and

in the second state, the quick sear valve assembly has a second maximum gas flow rate corresponding to a quick sear burner heat output of approximately 20,000 to 24,000 BTUs.

14. The grill of claim 2 , wherein the quick sear valve assembly is configured such that:

in the first state, the quick sear valve assembly has a first maximum gas flow rate corresponding to a quick sear burner heat output of approximately 12,000 BTUs, and

in the second state, the quick sear valve assembly has a second maximum gas flow rate corresponding to a quick sear burner heat output of approximately 28,000 BTUs.

15. The grill of claim 14 , wherein:

in the second state, gas is permitted to flow through both the main valve and the bypass valve into the quick sear burner;

the main valve is configured for a main valve maximum gas flow rate corresponding to a quick sear burner heat output of approximately 12,000 BTUs; and

the bypass valve is configured for a bypass valve maximum gas flow rate corresponding to a quick sear burner heat output of approximately 16,000 BTUs.

16. The grill of claim 1 , further comprising a quick sear heat shield positioned above the quick sear burner to laterally disperse the heat emitted by the quick sear burner.

17. The grill of claim 1 , further comprising a regular burner that is in communication with a regular valve assembly, the regular burner and regular valve assembly having a lower maximum heat output than the quick sear burner and the quick sear valve assembly.

18. The grill of claim 17 , wherein the cooking surface comprises:

a regular cooking surface positioned above the regular burner; and

a quick sear surface positioned above the quick sear burner;

wherein the regular cooking surface comprises a different surface pattern than the quick sear surface.

19. A quick sear valve assembly adapted to be positioned in fluid communication with a quick sear burner, comprising:

a main valve;

a bypass valve;

a gas inlet in communication with both the main valve and the bypass valve; and

an actuator for actuating the bypass valve, the actuator configured to switch the quick sear valve assembly between at least

a first mode in which gas is permitted to flow through the main valve but not the bypass valve, and

a second mode in which the bypass valve is actuated and gas is permitted to flow through the bypass valve.

20. The quick sear valve assembly of claim 19 , wherein, in the second state, gas is permitted to flow through both the main valve and the bypass valve.

21. The quick sear valve assembly of claim 19 , further comprising a valve shaft for control of gas flow through the main valve.

22. The quick sear valve assembly of claim 21 , wherein the bypass valve can be actuated only when the valve shaft is set to a high setting corresponding to substantially maximum gas flow through the main valve.

23. The quick sear valve assembly of claim 21 , wherein the actuator comprises the valve shaft.

24. The quick sear valve assembly of claim 22 , wherein:

gas flow through the main valve is controlled by rotating the valve shaft, and

gas flow through the bypass valve is controlled by pushing the valve shaft in an axial direction.

25. The quick sear valve assembly of claim 24 , wherein:

the actuator is configured to actuate the bypass valve only when an actuating force is applied by a user.

26. The quick sear valve assembly of claim 24 , further comprising:

an electromagnet proximate the actuator,

a timer, and

a power source for selectively energizing the electromagnet and the timer,

wherein movement of the actuator in a predetermined direction permits gas flow through the bypass valve, causes the actuator to come in magnetic contact with the electromagnet, causes power to be supplied for energizing the electromagnet, and activates the timer, and

further wherein the timer enables the electromagnet to remain sufficiently energized to hold the actuator in place to allow continued gas flow through the bypass valve for the predetermined duration of time.
