Description

The subject of the present invention is a kitchen fume hood, which is equipped with a device which is suitable for illuminating a cooking hob below and the surrounding areas of the hob.

As is known, kitchen hoods are mounted above a hob, fixed to the wall or suspended from the ceiling (in the latter case they are commonly referred to as island hoods) and are divided into two main types: the extractor hoods, which are the To dissipate fumes, odors and vapors from cooking to the external environment, and the filtering extractor hoods, which return these fluids to the domestic environment after they have been cleaned by filters provided for this purpose.

To simplify the explanations, these two types of fume hoods are referred to in the following as "kitchen fume hoods".

In addition to the absolutely functional components for the suction effect or filter effect, the kitchen hoods are generally equipped with luminaires that are suitable for illuminating the hob below. Such lights are usually located in the lower part of the structure of the hood and therefore emit their light in a substantially vertical direction on the cooking surface.

In this way, the view of the hob and its use are facilitated for the user person.

However, such types of kitchen hoods illuminate only the area below them to the detriment of the hob adjacent areas which are of particular use for performing various activities prior to cooking food and meals; Therefore, such surfaces of a worktop (also referred to as Worktop) of a domestic kitchen, the risk that they are hardly used or not exploited.

According to some constructive variants, the kitchen hood can be equipped with additional lighting devices that are functionally independent and only adjacent to the hob and / or adjacent to the above-mentioned lights that are suitable for illuminating the underlying cooktop Serve areas.

This can be achieved by providing, for example, a plurality of additional lamps (or similar devices), each oriented in the direction of the surfaces to be illuminated which are adjacent to and outside the hob.

This inevitably involves a complication in the design and manufacturing processes of kitchen hoods, an increase in their production costs and selling prices, as well as the risk of compromising their aesthetics.

The main object of the present invention is to overcome the drawbacks set forth above by providing a kitchen fume hood whose lighting system for an underlying cooktop is capable of advantageously illuminating the areas adjacent thereto as well.

These and other objects, which are pointed out below, are achieved with the kitchen fume hood, which is explained in the following description and in the appended claims, which form an integral part of the description.

In the following, the features of the invention will be described referring to the reference numerals contained in the figures.

It is to be understood that the above figures, while schematic, represent the components of the apparatus in terms of proportions, including their dimensions and spatial orientations, which are not necessarily but in any case consistent with one or more possible embodiments.

It should also be noted that any term related to a dimension or spatial situation (such as "lower", "upper", "inner", "outer", "front" r) "," rear "and the like) refers to the position from which the fume hood and its components are seen, when they are in Betriebsanordnung.

If some features are emphasized rather than others, this does not necessarily mean that the detail shown in the accompanying drawings is to scale.

The reference numeral 1 denotes a kitchen extractor hood in its entirety, which is shown here in the suction version with trigger 10 for discharging the fumes and as a hung on a wall type; However, the teachings of the present patent may also be applied to a filtering fume hood not provided with the abovementioned fume hood, as well as to any other known types of fume hoods, such as island-type fume hoods or those in which any such fume hoods are used other shape and / or any other aesthetic design is realized.

• - einem Beleuchtungssystem 2, das dazu geeignet ist, ein darunter liegendes Kochfeld PC (dargestellt in 4a oder 4b) zu beleuchten, und
• - einer Steuerungs-Schnittstelle (nicht dargestellt) zur Betätigung und zum Management der Funktionen der Abzugshaube 1, zum Beispiel zum Einschalten des Beleuchtungssystems 2, wobei sich die Schnittstelle an einer Position befindet, die für die benutzende Person leicht erreichbar ist.

As known from the prior art, the structure 11 of the hood 1 (hereinafter referred to as "box-shaped structure or body 11") in addition to the housing of the filter unit 12, the at least one mechanical filter and / or activated carbon filter 120, 121, 122 equipped with

• a lighting system 2 adapted to provide an underlying cooktop PC (shown in FIG 4a or 4b ) and
• - A control interface (not shown) for operating and managing the functions of the hood 1, for example, to turn on the lighting system 2, wherein the interface is located at a position that is easily accessible to the person using.

As is known, the engine group (not shown in the accompanying figures) having at least the fan for sucking cooking fumes and vapors may be inside the trigger 10, if present, or alternatively, of suitable dimensions and shape, be housed in the box-shaped structure 11.

Normally, the lighting system 2 may be mounted on the underside or "bottom" 110 of the box-like structure 11 so as to illuminate the underlying cooktop PC.

According to the invention, the lighting system 2 is advantageously designed and / or manufactured such that furthermore the areas adjacent to and / or adjacent to the hob PC can be illuminated.

As will be seen in detail in the course of this paper and in 2a and or 2 B 2, the illumination system 2 may comprise at least one light-emitting element 20 which may be rotated in order to illuminate one or more of the regions adjacent to and / or adjacent to the cooktop PC.

According to an advantageous embodiment, the at least one light-emitting element 20 may have a holding device 200, preferably in a vertical position, which is attached to the base 110 and protrudes from the base 110 and serves to "carry" suitable lighting devices, such as LEDs (light-emitting diodes). Lamps, halogen lamps, incandescent lamps, fluorescent tubes or the like.

These lighting devices can for example be mounted directly on an arm 201, which is connected at its first end to the mounting device 200 and lies substantially on a plane which is parallel to the bottom 110 of the box-shaped body 11 of the hood 1 and below it.

Of course, there is no reason to oppose the possibility that the arm 201 may be inclined with respect to it, as opposed to a substantially horizontal position orthogonal to the support 200, as shown in the attached figures, provided that there is always an optimum illumination of at least that below lying cooktop PC is guaranteed.

In a first operating position, the arm 201 is aligned with its free end 202, which is opposite to the attached to the holder 200 end, to the vertical center axis X-X of the hood 1 out. Hereinafter, this first position, which allows the optimal illumination of the hob PC, referred to as "standard position".

According to the invention, the holder 200 of the lighting system 2 at the bottom 110 of the hood 1 by couplings, connectors or hinges may be connected to the floor 110 of the fume hood 1 to allow, as already mentioned, their rotation and to allow for the adjustability of the arm 201 supported by them.

Alternatively, the arm 201 itself could be rotatably attached to the bracket 200 (for example with corresponding hinges or couplings), the bracket 200 consequently being fixed with respect to the floor 110 of the hood 1.

In both variants, such rotation allows to better illuminate specific or limited areas of the cooktop PC (for example, the area where cooking is actually being performed) or the areas around it.

In this context is on 2 B and or 4a reference is made to see how due to the above rotation of the arm 201 is aligned with its free end 202 to the outside of the hood 1, which consequently allows the illumination of at least the surfaces of the worktop T of a kitchen C, which is adjacent to the hob PC and outside of it.

Such joints or couplings may be of the type permitting rotation of the luminescent element 20 in a limited number of fixed and predetermined positions, for example of the bayonet type, or of known devices which instead provide continuous and unlimited angular rotation allow.

It is clear how a rotation of the lighting element 20 of 360 ° starting from the "standard position" is possible if certain design conditions and / or installation conditions are met. Such a rotation can be carried out, for example, with island-type hoods 1 without any difficulty, whereas with wall-mounted hoods 1 a suitable dimensioning of the lighting element 20 or its arrangement at the level of the front edge 114 of the box-like structure 11 may be required prevent disturbing obstructions by the wall itself or the surrounding furniture.

There is nothing to prevent that according to an alternative embodiment, the alignment of the illumination device of the at least one lighting element 20 by providing a holder 200 and / or an arm 201 may be made of a flexible and variably adjustable and alignable material (for example, from flexible tubular or tubular elements, coiled hose, flexible hose or the like may exist), instead of providing them rotatably from the outset.

Furthermore, it is indicated how the power supply of the at least one luminous element 20 can take place, namely by providing a seat or housing for accommodating an electrical connection (not explicitly shown in the attached figures) at the bottom 110 of the box-shaped body 11 of the extractor hood 1 connected to the mains.

The holder 200 has corresponding means for electrical and mechanical connection to the terminal, for example a connector.

• - während des Herstellungsprozesses mit der Abzugshaube 1 integriert werden; der Hersteller wird daher vorsehen, die Ausführung des Sitzes oder Gehäuses am Boden 110 des kastenförmigen Körpers 11 der Abzugshaube 1 und die Installation des elektrischen Anschlusses oder Verbinders direkt im Unternehmen vorzunehmen;
• - als Zubehör zu der Abzugshaube 1 nachträglich eingebaut werden; dies würde einen einfachen Eingriff durch einen Fachmann oder den Endnutzer selbst erfordern, um das eine Leuchtelement 20 oder mehrere Leuchtelemente 20 mit dem elektrischen Anschluss oder Verbinder zu verbinden.

The at least one luminous element 20 can

• - Be integrated during the manufacturing process with the hood 1; the manufacturer will therefore provide for the execution of the seat or housing at the bottom 110 of the box-shaped body 11 of the hood 1 and the installation of the electrical connection or connector directly in the company;
• - be retrofitted as an accessory to the hood 1; this would require simple intervention by a person skilled in the art or the end user himself to connect the one or more light emitting elements 20 to the electrical connector or connector.

There is nothing to prevent that in a simpler and more economical embodiment of the invention, the power supply of the lighting system 2 can be done advantageously by power supply facilities such as batteries or the like, whereby the electrical connection is virtually eliminated.

• - manuell durch die Benutzungsperson durch geeignete mechanische, elektrische oder digitale EIN/AUS-Schalteinrichtungen der Abzugshaube 1 und/oder durch Funkfernsteuerungen und/oder
• - automatisch durch eine Steuereinheit (nicht dargestellt) der Abzugshaube 1 gemäß ihrem Einschalten oder Ausschalten.

The switching on and / or off of the at least one lighting element 20 can also be controlled

• - Manually by the user by suitable mechanical, electrical or digital ON / OFF switching devices of the hood 1 and / or by radio remote controls and / or
• - Automatically by a control unit (not shown) of the hood 1 according to their switching on or off.

• - manuell durch die Benutzungsperson je nach deren Bedürfnis, wobei in diesem Fall das Leuchtelement 20 mit Griffen oder ähnlichen Mitteln ausgestattet sein kann, die diesen Vorgang erleichtern, und/oder
• - elektronisch in Abhängigkeit von den Bereichen des Kochfelds PC oder der benachbarten Bereiche, die für eine Kochtätigkeit und/oder die Zubereitung von Speisen oder Gerichten oder dergleichen von Interesse sind.

Similarly, the rotation of the at least one lighting element 20 can be carried out as follows:

• - manually by the user according to their needs, in which case the lighting element 20 may be provided with handles or similar means facilitating this operation, and / or
• electronically depending on the areas of the cooktop PC or adjacent areas of interest for cooking and / or the preparation of food or dishes or the like.

In this latter case, for example, the fume hood 1 could be equipped with one or more sensor devices which can detect whether and which areas of the cooktop PC and / or adjacent areas are of interest to such activities, and accordingly Align at least one lighting element 20, and also with suitable actuators (for example, a small electric motor).

Such sensor devices may include, but are not limited to, temperature sensors, proximity sensors, motion sensors, electronic noses, or the like, alternatively or in combination.

After the extractor hood 1 of the invention has been dealt with in its more general form, a preferred embodiment thereof is described in the following, in which a lighting system 2 is provided which has two lighting elements 20.

As can be clearly seen from the attached figures, the two lighting elements 20 are mounted on the floor 110 of the fume hood 1 according to the modalities described above and preferably symmetrically with respect to their vertical central axis X-X.

3a shows, for example, that the two lighting elements 20 are aligned with the ends 202 of their arms 201 to the axis XX of the hood 1, so as to ensure the complete and optimal illumination of the hob PC.

At the same time it allows the rotation of these light elements 20, in addition to the in 3a represented "standard position" to cover a very wide variety of operating positions.

Some examples of the above are in the 3b . 3c and 3d shown schematically.

In detail shows 3b the two lighting elements 20 with their arms rotated 201 to illuminate mainly the outer and the hob PC adjacent areas; in 3c is only one of the lighting elements 20 is rotated and aligned by the hood 1 to the outside, while 3d illustrates some of the various intermediate positions that each light-emitting element 20 can assume.

It will be understood that numerous modifications of the invention described above are possible to those skilled in the art without thereby departing from the scope of the novel and inventive concept of the invention; It is thus clear that in the practice of the invention, the various components described above may be replaced by elements that are technically equivalent.

For example, there is nothing against the fact that the at least one lighting element 20, instead of positioning in the vicinity of the rear edge 111 of the box-shaped body 11 of the hood 1, at the level of the front edge 114 or at its side edges 112, 113 may be provided to be able to correspond to any installation requirement in this way, as already described in part.

The above-mentioned mounting device 200 may also be adjustable in height by known technical measures; it may, for example, be telescopically extendable and collapsible or generally vertically displaceable to adjust the distance of the arm 201 connected thereto from the floor 110 of the hood 1 or, which is equivalent, to the underlying hob PC or underlying worktop T.

The particular geometry that has been developed for the lighting element 20, in particular the presence of the arm 201, also allows its use as a carrier and hanger for small utensils or kitchen utensils.

In summary, the lighting system 2 of the hood 1 according to the invention, a luminous element 20 or more lighting elements 20, which in turn have at least one mounting means 200 for suitable lamps, which is preferably attached to the bottom 110 of the box-shaped body 11 of the hood 1 and protrudes from him and allows to change the orientation of the lighting devices to illuminate different areas of the underlying cooktop PC and / or further the adjoining or adjacent areas of the worktop T.

The lighting devices may, as already shown, preferably be attached to an arm 201 which is attached to the holder 200, while their orientation may be changed by making the holder 200 and / or the arm 201 of a flexible and variably adjustable material is (which may for example consist of flexible tubular or tubular elements, coiled hose, flexible hose or the like), and / or by a rotation of at least the holder 200 and / or its arm 201th

Finally, it will be seen how it is possible with the hood 1 of the present invention to overcome the disadvantages of the prior art by enabling its lighting system 2, which is normally used to illuminate an underlying hob, also the adjoining and / or illuminate adjacent areas.

Namely, according to the invention, the lighting system 2 is capable of illuminating either only the cooktop PC or only one or more of the adjoining areas, or both, depending on the requirements.

This not only favors the usability of the cooktop PC under the fume hood 1, but also those areas of the cooktop that are normally not fully occupied, without it being otherwise necessary to carry out a new planning and / or substantial structural and / or aesthetic To make modifications to traditional hoods.
