Description

DESCRIPTION OF THE INVENTION

[0001] The object of this invention, as expressed in the summary of this description, consists of an "IMPROVED SMOKE EXTRACTOR HOOD", of the type used in kitchens in homes and restaurants.

[0002] At present the use of extractor hoods in kitchens is quite widespread.

[0003] These are basically made up of a smoke collection hood, a smoke extractor mechanism which must be turned on manually and a smoke outflow duct.

[0004] This arrangement presents a series of drawbacks. In the first place, the activation of the extractor mechanism is manual. In other words, when an excessive accumulation of smoke is observed, the cook turns it on manually, and on many occasions this is done too late and the damage that has been caused is irreparable.

[0005] Another drawback is that in time the hoods become coated with accumulated grease which can come to block the outflow duct.

[0006] For all these reasons the innovative invention which is the subject of this description report has been developed.

[0007] This innovative improved smoke extractor hood consists of a traditional type smoke extractor mechanism as well as a smoke outflow duct and the traditional smoke collection hood.

[0008] It also contains a hood protector consisting of a detector cell connected both to the smoke extractor mechanism and to an audible or visual alarm.

[0009] With this it becomes possible to dispense with the on-off switch as unnecessary, since the cell itself acts as a smoke detector, activating the traditional smoke extractor mechanism.

[0010] This cell, in the event of fire or excess smoke, activates the alarm which warns of the danger.

[0011] It also detects excessive accumulation of grease, which also sets off the alarm.

[0012] Thanks to the introduction of the detector as part of the innovative improved smoke extractor hood, an additional protection feature of the hood is obtained, for the purpose of eliminating excess smoke, grease or the outbreak of fire.

DESCRIPTION OF THE DRAWINGS

[0013] For the purpose of illustrating all that has been stated up to this point, the present description is accompanied by a page of drawings, to be considered as an integral part of the description, showing an example of its embodiment in a simplified and schematic fashion. This is purely illustrative in nature and should not be understood to delimit the practical possibilities of the invention.

[0014] In these drawings figure 1 corresponds to a view in perspective of the hood, in which can be observed the smoke detector cell and the alarm connected to it.

DESCRIPTION OF A PRACTICAL CASE

[0015] The innovative improved smoke extractor hood consists of a smoke collection hood (1), a traditional internal smoke extractor mechanism (2) as well as a smoke outflow duct (3).

[0016] It also consists of a hood protector (4) made up of a smoke detector cell connected both to the smoke extractor mechanism (2) and to an audible or visual alarm (5).

[0017] Having made the description referred to in the preceding report, it is necessary to emphasise that details of the practical embodiment of the idea set forth here may undergo minor changes, always based on the fundamental principles of the idea, which are essentially those expressed in the paragraphs of the description.

[0018] In fact, the Law of Patents currently in force defines changes in the shape, dimensions, proportions and materials of an already patented object as non-patentable, thus stating the criteria of the legislator in the sense that once an idea has been patented which may be developed into a practical reality suitable for industrial exploitation, no one may make use of it so as, on the pretext of having introduced slight modifications, to present it as new and as belonging to him.

[0019] Having established the concept here expressed, the note of claims is drafted below, thus summarising the innovations which the petitioner wishes to claim:

NOTE

[0020] In brief, the privilege of exclusive commercial use which is being applied for is based on the following claims:
