An automatic stovetop fire suppressor is activated by a shuttle actuator. The self-contained and closed container device provides a gradual release of a fire suppressing agent in a desired distribution pattern. A method of reliable and spatial agent release are provided herein. A plastic cone shaped lid seals on the bottom of a can and forms a closed container. The closed container is filled with a fire suppressing agent. An initiator charge is housed external to the container of fire suppressing agent and is fuse activated. The activated charge displaces the shuttle. As the shuttle displaces, vertical support for the bottom cone lid is removed and a compression spring breaks a circumferential seal between the bottom lid and container cylindrical sidewall and lowers the bottom lid exposing a radial opening. Fire suppressing agent flows out of the radial opening, suppressing a stovetop fire.

A system for delivering a cooling agent to cooking appliance to aid in fire suppression is disclosed, which includes a fuel delivery path extending from a source of cooking fuel to a heating element of the cooking appliance, a source of cooling agent selectively in fluid communication with the fuel delivery path, and a valve assembly associated with the fuel delivery path and the source of cooling agent, wherein the valve assembly is configured to control the delivery of cooling agent to the heating element of the cooking appliance and shut off the heating element from the source of cooking fuel in the event of a fire.

A fire suppression system is disclosed. The fire suppression system comprises a first storage cylinder configured for storing a first suppression solution. The system comprises a second storage cylinder operatively connected to the first storage cylinder. The second storage cylinder is configured for storing a second suppression solution, wherein in response to a detection of a fire condition, the first storage cylinder is configured to release the first solution into the second storage cylinder to cause the second solution to be delivered first during a first phase of a discharge.

A method of responding to a condition in an exhaust ventilation system that has an exhaust hood includes receiving, at a control module, an exhaust air temperature signal representing a temperature of the exhaust air in a vicinity of the exhaust hood, the exhaust air temperature signal being generated by a temperature sensor. The method also includes receiving a radiant temperature signal representing a temperature of a surface of a cooking appliance that generates the exhaust air, the radiant temperature signal being generated by a radiant temperature sensor. Further, the method includes receiving a pressure signal representing the pressure in the hood and determining a state of the cooking appliance based on the received exhaust air temperature signal, the received radiant temperature signal, and the received pressure signal. Finally, the method responds to the determined appliance state by outputting a control signal from the control module.

A gas burner assembly and a method of operating the same are provided. The gas burner assembly includes a gas burner and a fuel regulating device for providing a flow of fuel to the gas burner to heat a cooking utensil. The method is a closed loop cooking method that includes monitoring the temperature of the cooking utensil and adjusting the power output of the burner accordingly to drive the utensil temperature to a target cooking temperature or profile. However, the burner power is limited to a maximum fuel flow rate, e.g., to ensure safe operation and to prevent the flames from the gas burner from engulfing the sides of the cooking utensil.

A system for delivering a fire suppression agent to an obstructed cooking appliance is disclosed, which includes a fuel delivery path extending from a source of cooking fuel to a burner of the cooking appliance, a source of fire suppression agent selectively in fluid communication with the fuel delivery path, and a valve assembly associated with the fuel delivery path and the source of fire suppression agent, wherein the valve assembly is configured to control the delivery of fire suppression agent to the burner of the cooking appliance and shut off the burner from the source of cooking fuel.

Systems and methods for remote monitoring of mechanical fire suppression systems are provided. For example, some embodiments generally provide for a smart fire suppression system with integrated sensors and communication technology to monitor the current state of the fire suppression system and notify various monitoring platforms, service providers, equipment manufacturers and/or others of the current state. In some embodiments, various sensors (e.g., micro switches) can be used to detect and report the status of the cartridge, activation status of the system, and/or the status of the detection line. Additional sensors and actuators may be also be included within the smart fire suppression system to allow monitoring of different states (e.g., temperature) and control the appliance and/or building utilities.

An oven appliance and flame arrester therefore are provided herein. The flame arrester may include a first member and a second member. The first member may extend in a lateral direction along a portion of the opening. The first member may define a chamber aperture extending along an arrest axis in fluid communication with the cooking chamber. The second member may extend from the first member and away from the cooking chamber. The second member may define an intake aperture extending non-parallel to the arrest axis. A fluid passage may be defined between the first member and the second member in fluid communication between the intake aperture and the chamber aperture.

A cooking system includes an appliance configured to cook food products, a fire suppressant supply configured to selectively provide fire suppressant agent, and a conduit. The appliance includes a food receptacle and a cover selectively repositionable between a fully open position and a closed position. The cover defines an internal volume configured to contain the food products during cooking, a fluid aperture fluidly coupled to the internal volume, and an access aperture through which the food products may be introduced into the internal volume. The cover extends at least partway across the access aperture in the closed position. The conduit fluidly couples the fire suppressant supply to the fluid aperture. The fire suppressant supply and the conduit are configured to introduce the fire suppressant agent into the internal volume of the food receptacle at least when the cover is in the closed position.

A cooking appliance including a cooking vessel temperature monitoring and fire prevention system, includes a gas burner, a cooking vessel support configured to support a cooking vessel above the gas burner, a temperature sensor integrated with the cooking vessel support, the temperature sensor configured to be in thermal contact with the cooking vessel supported on the cooking vessel support and to detect a temperature of the cooking vessel, and a thermal insulation integrated with the support and separating the temperature sensor from the cooking vessel support.
