Kitchen fire suppression aiming systems and methods
A method of suppressing a kitchen fire includes detecting a fire and identifying a location of the fire with a tracking system, aiming a nozzle at the location, and releasing an agent through the nozzle at the location.
1. A method of suppressing a kitchen fire, the method comprising:
detecting a fire and identifying a location of the fire with a tracking system;
aiming a nozzle at the location by moving the nozzle laterally along a track within a hood of an appliance, wherein the track includes an X-axis track portion for movement of the nozzle in an X-axis direction and a Y-axis track portion for movement of the nozzle in a Y-axis direction, such that the nozzle is moveable to a desired X, Y coordinate position within the hood based on the detecting; and
releasing agent through the nozzle at the location.
2. The method of claim 1 , wherein the agent is stored in a cylinder not movable along the track, and the nozzle is in fluid communication with the cylinder through a hose to allow movement of the nozzle relative to the cylinder.
3. The method of claim 1 , wherein the aiming further includes rotatably moving the nozzle about an axis to a desired circumferential position.
4. The method of claim 3 , wherein the aiming further includes angularly moving the nozzle to a desired angle between the nozzle and the axis.
5. The method of claim 1 , wherein the aiming includes:
detecting an object between a target area and the nozzle; and
moving the nozzle such that the object is not between the target area and the nozzle.
6. The method of claim 1 , wherein the tracking system includes at least one optical sensor.
7. The method of claim 1 , comprising:
receiving temperature information from a chip in a piece of cookware, wherein the detecting includes determining the fire exists based on the temperature information.
8. The method of claim 7 , comprising:
identifying a location of the chip with a positioning system.
9. The method of claim 8 , where the positioning system is a radio frequency identification system.
10. A fire suppression system for a kitchen, comprising:
a tracking system configured to sense a location of a fire in the kitchen;
an agent cylinder; and
a nozzle in fluid communication with the agent cylinder and movable laterally along a track within a hood to a select position based on the sensing and configured to release fire suppression agent onto the fire, wherein the track includes an X-axis track portion for movement of the nozzle in an X-axis direction and a Y-axis track portion for movement of the nozzle in a Y-axis direction, such that the nozzle is moveable to a desired X, Y coordinate position within the hood.
11. The system of claim 10 , comprising a swivel joint pivotally attached to the nozzle, wherein the nozzle is further movable rotatably about an axis to a desired circumferential position to the select position, wherein the rotatable movement includes rotation of the swivel joint.
12. The system of claim 10 , further comprising a controller configured to send control signals to move the nozzle based on the sensing.
13. The system of claim 10 , wherein the tracking system includes an infrared sensor for sensing the location of the fire.
14. The system of claim 10 , wherein the nozzle is in fluid communication with the agent cylinder through a flexible hose, and the agent cylinder is not movable along the track, such that the flexible hose allows movement of the nozzle relative to the cylinder.
15. A fire suppression system for a kitchen, comprising:
a tracking system configured to sense a location of a fire in the kitchen;
an agent cylinder stored in a fixed position;
a nozzle in fluid communication with the agent cylinder through a flexible hose to allow for movement of the nozzle relative to the cylinder, the nozzle movable laterally along a track within a hood to a select position based on the sensing and configured to release fire suppression agent onto the fire; wherein the track includes an X-axis portion for movement of the nozzle in an X-axis direction, a Y-axis track portion for movement of the nozzle in a Y-axis direction; and
a swivel joint pivotally attached to the nozzle, wherein the nozzle is further movable rotatably about an axis to a desired circumferential position to the select position by rotating the swivel joint, and the nozzle is movable angularly to vary an angle between the nozzle and the axis to the select position.
16. The fire suppression system of claim 15 , wherein the tracking system is configured to detect an object between a target area and the nozzle and move the nozzle to the select position such that the object is not between the target area and the nozzle.
17. The fire suppression system of claim 15 , comprising a fixture holding the nozzle and including a plurality of openings, wherein the track is slidably received within then plurality of openings, and the flexible hose extends from the cylinder to the fixture.
18. The method of claim 1 , wherein the nozzle includes a fixture with openings for slideably receiving the X-axis track portion and the Y-axis track portion.
19. The fire suppression system of claim 15 , wherein the track includes a first perimeter track portion, a second perimeter track portion, wherein the X-axis track portion is slideable along the first perimeter track portion, and the Y-axis track portion is slideable along the second perimeter track portion, such that the nozzle is moveable to a desired X, Y coordinate position within the hood based on the sensed location, wherein the nozzle includes a fixture with openings for slideably receiving the X-axis track portion and the Y-axis track portion.
20. The fire suppression system of claim 15 , where the agent cylinder is stored next to the hood.
