Embodiment Construction

[0013] figure 1 An example of a fire suppression system in combination with an appliance is shown. Such devices may include figure 1 The cooking appliance 10 shown in. Examples of such appliances include, but are not limited to, fryers, vertical grills, and pizza ovens. The fire suppression system may include a liquid agent storage tank 12 holding a liquid agent (not shown) and a release assembly having a release mechanism. For example, the release mechanism may include a lever 14 for activating the fire suppression system, wherein a pull of the lever 14 is transmitted to the liquid agent tank 12 via a wire 16 . The fire suppression system may also include one or more nozzles 24 positioned for directing fire suppressant to any portion of the cooking appliance 10 .

[0014] The liquid storage tank 12 may be connected to the nozzle by a combination of hard lines and flexible hoses. In particular, as figure 1 As shown in , hard lines 18 , 34 , 36 , 38 , 40 in combination...

Abstract

A fire suppression system for an appliance is provided. The fire suppression system includes a fire suppression storage container for storing a fire suppression agent, a detection system that interacts with a release assembly, a release assembly in communication with the fire suppression storage container for controlling the release of the fire suppression agent from the fire suppression storage container, a nozzle in a fixed position relative to the appliance, and a fire suppression agent conduit from the fire suppression storage container to the nozzle. The fire suppression agent conduit acts as a conduit for the fire suppression agent from the fire suppression storage container to the nozzle. The fire suppression agent conduit may partly include hard piping and partly include a flexible hose. Since the flexible hose is bendable, it enables movement of the appliance so that the area around the appliance may be cleaned. Further, swivel connectors may connect the flexible hose with the hard piping, thereby reducing the possibility that the flexible hose kinks during movement of the appliance. In addition, a restraining cable may be connected between the appliance and a wall, thereby limiting the appliance movement and reducing the possibility of damage to the flexible hose.

Description

[0001] References to related applications [0002] This application claims priority to US Application 12 / 026,212, filed February 5, 2008, which is hereby incorporated by reference in its entirety. Background technique [0003] Cooking appliances, such as those found in restaurants, present a fire potential. To reduce this possibility, fire suppression systems can be configured to work in conjunction with cooking appliances. A basic fire suppression system includes a liquid agent tank holding a liquid agent such as fire suppression liquid, a release assembly with a release mechanism such as a lever to activate the fire suppression system, nozzles, and other accessories. Black iron pipes are used to connect liquid preparation storage tanks and nozzles. Nozzles direct liquid formulations to various locations and can be positioned for protective appliances, range hood ducts and plenums. Typically, the nozzle is attached to the range hood duct. However, some appliances are plu...
