Abstract

Safety extractor hood. The hood (1) constituted with the design and the conventional characteristics of any type of hoods used for the extraction of fumes in domestic and industrial kitchens, has the particularity of including as an integral part thereof a fire extinguisher (4) based on a extinguishing agent remaining in an enclosure (3) with front access (2) of the bell (1) itself, from whose extinguisher (4) a duct (5) is projected with nozzles (6) of automatic activation when the fire is detected for projecting the extinguishing agent vertically on the fire caused in, for example, the cooking of food on the kitchen in which the bell (1) itself is applied.

Description

Safety hood.

Object of the invention

The present invention relates to a bell safety extractor and more specifically to a hood equipped with a fire detection and extinguishing system, both for use Domestic as for industrial use.

The object of the invention is to integrate into a industrial or domestic extractor hood of a fire extinguisher fires that before any fire incident this is extinguished automatically using an extinguishing agent.

Background of the invention

It is well known that the function most important of the hoods mounted in kitchens or other similar places, is to eliminate heat, vapors (vapors of fats, oils and water) and fumes produced during the process of cooking of food, as well as the possible products of the combustion, all in order to prevent fouling of enclosures and fixtures, the condensation of water vapor on cold surfaces, and the formation of high levels of odors.

The use of extractor hoods carries risks that may occur from own activity in the place of implementation of the hood, such as cooking, that is, there is a possibility of fire due to cooking operations They are held in a kitchen.

Therefore, the common denominator of extractor hoods is extracting or sucking harmful fumes originated in the cooking of food, establishing itself as differences between some manufacturers what is considered as a filtration system that incorporates each hood, as well as the aesthetics of these.

The existence or not of equipment is unknown. fire extraction, detection and extinction, although at the level industrial and in kitchens, for example restaurants, there are fire extinguishing systems, based on a plurality of automatically releasable spray heads in combination with a high pressure hydraulic accumulator that works as a driving unit when a spray head is released because of a declared fire, all as claimed in the W 9416773, although the fire extinguishing system is not integrated into the hood, but it is an independent installation, such as any other enclosure, be it a garage, a commercial establishment, etc.

On the other hand, the Model of Spanish utility with publication number 0247200, in which describes a fume hood with device firewall, this one based on setting on the top cover of the bell a drill on which a plate or strap is placed provided with a central hole over which it is welded perpendicularly and oriented towards the shot a cylindrical body hollow carrier of a helical spring, in combination with another series of elements that determine a system as a whole firewall, even if it is not considered a fire extinguisher integrated in the hood.

Description of the invention

The extractor hood that is recommended presents the particularity that incorporates an integrated fire extinguisher constituted by a cylindrical body with an extinguishing agent, of which a duct is derived, all preferably running through the inside the bell, so that duct is hidden although with nozzles open to the outside so that in case of fire, automatically, act and carry out the release of the extinguishing agent, with the corresponding fire extinguishing originated in cooking food on the kitchen located under the own bell.

In short, it is an integrated system by the manufacturer of the hood in its manufacturing process, so that the retrofit of the team is perfect, not having the drawbacks of applying the rest of the systems to the various bell designs, since according to the invention the system application can be considered as "custom", of so that its activation by an authorized installer will put into operation a simple, easy process that does not requires specific tools or installation time, resulting in a clean process for the client.

The extinguisher itself constitutes a fixed system with channeling and automatic trip, which is integrated in the hood and that is based on an extinguishing agent, which results clean, environmentally friendly, leaving no residue that is dangerous or difficult to remove and without risk of causing damage to people who may be present at the time of fire extinguisher activation

Therefore, it is not a portable fire extinguisher or an installation outside the hood, but rather it is a fire extinguisher with the aforementioned characteristics that is integrated in the extractor hood itself, preferably inside, so it also complies Its function as such includes the assurance that in any fire incident it can be stifled by releasing the extinguishing agent.
tor.

As is evident, the extractor hood does not It is only feasible for application at the domestic level, but at the level industrial, as is the hospitality sector, constituting a clean, aesthetic system without external and additional components as usually happens conventionally.

Finally say that the system does not require no manipulation by the user, since it is totally automatic, thus avoiding errors in the operation of the system by the user that have led to risk situations, by example, when they were shot involuntarily and by mistake in kitchens installations with CO2 gas that have caused injuries and even deaths

Description of the drawings

To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

Figure 1.- Shows a representation schematic of a conventional extractor hood, as well as a fire extinguishing system carried out in accordance with the purpose of the invention, in a position to integrate into the hood.

Figure 2.- Shows a front view of the hood of the previous figure with the extinguishing system of integrated fires in it.

Figure 3.- Shows an elevation view sectioned side of the hood with the fire extinguishing system fires of the invention.

Preferred Embodiment of the Invention

As you can see in the referred figures, the extractor hood (1) that can have any configuration and design, has the peculiarity that its forehead is affected of a window (2) with practicable cover, after which it is established a hollow enclosure (3) in which a fire extinguisher is located of fire (4) based on an extinguishing agent, whose extinguisher (4) a duct (5) projected on a plurality of nozzles is projected (6) that upon detection of a fire they automatically activate and push down, as depicted in figures 2 and 3, the extinguishing agent, suffocating the corresponding fire.

The bell, as is conventional, will incorporate the corresponding perimeter grease cutter (7), the fat channel (8), a drain element (9) and its corresponding neck (10) of coupling to the evacuation duct, all as it is conventional.

Claims (1)

1. Safety extractor hood, which being of the type that is included in both domestic and industrial kitchens, such as restaurants, hotels and others, is characterized by the fact that as an integral part of it there is a fire extinguisher (4 ) with an extinguishing agent, which is located in an enclosure or compartment (3) disposed frontally in the hood and with access through a window (2) with practicable cover, it being provided that a duct (4) is projected from the extinguisher (4). 5) with a plurality of automatic activation nozzles (6) at the time of detection of a fire, to project the corresponding extinguishing agent contained in the extinguisher (4) on the fire.
