Description

MODULAR COOKER TOP The present invention relates to a particular type of cooker top which operates either with gas burners or with electric plates and is used in particular in recessed fittings. In order better to describe the invention, the following description relates to a cooker top provided with gas burners, but it is understood that whatever is described can equally well also be applied to cooker tops provided with electric plates, by making the appropriate modifications which can be performed by any person skilled in the art.
At present, the functional parts of a cooker top and connection of the gas supplies are integrated with the work surfaces or with support cases disposed beneath the surface itself in various forms, according to the type of device and the production technique used.
In cooker tops which are to occupy the least possible vertical space and have the simplest possible design, there is generally a gas distribution component which is disposed between the union for the intake of gas into the appliance and a plurality of taps used in order to open and regulate the intake of gas to the various burners.
The said component (which is known in the trade as a "ramp"), is used substantially in order to distribute the gas to the said taps, and normally consists of a tubular metal duct, which is hermetically sealed against the gas operating pressures, is closed at one end, and is connected at the opposite end to the gas intake union, optionally by means of a further duct which in general is resilient.
It is known that in the surface of the said ramp holes are provided, inside which the aforementioned gas flow regulation taps are inserted and are sealed hermetically, using various techniques.
Owing to the somewhat delicate nature of the function required of them, these components must normally consist of rather costly materials such as steel or brass, and must be processed and assembled using precision techniques.
Their dimensions must also be specific to each type of cooking appliance in which they are used, either because they must admit gas into the taps, the distances of which from one another may vary, or because the distance between the two taps furthest apart may obviously vary from one appliance to another.
However cooker tops of this type and other similar types have certain disadvantages, even though they are universally used: - the first disadvantage is derived from the fact that the various components associated with burners of different sizes, must have different dimensions, the considerable proliferation of components owing to the lack of standardisation thus giving rise to high costs; - the second disadvantage is derived from the fact that the complexity of the said assemblies prevents or impedes assembly thereof using automated techniques; - a further disadvantage is derived from the fact that in order to obtain operation using all types of gas, it is normally necessary to dismantle a large part of the burner assembly in order to replace the gas outlet nozzle.
Additionally, account must be taken of factors such as the lack of compactness of the assembly, and the existence of many processing operations, some of which require high precision, with the production of large volumes of processing waste.
All of this leads to a series of disadvantages which can easily be imagined: complex processing and assembly, a high cost, and considerable proliferation of components owing to the lack of standardisation.
It is desirable, and this is the main object of the invention, to provide a type of working surface which, as well as being constructed by means of more economic and simpler techniques, enables the above-described disadvantages to be avoided, and in particular provides a high level of modularity of composition.
This object is obtained by means of a cooker top in accordance with the following Claims.
The invention will be better understood from the following description, provided purely by way of non-limiting example and with reference to the attached drawings, in which: - Figure 1 shows a perspective view of a partially dismantled cooker top according to the invention; - Figure 2 shows a simplified assembly of some of the modules in Figure 1.
The structure and operation of the invention are shown schematically with reference to the Figures.
Substantially it consists of eliminating the various separate components and parts which constitute the conventional working surface, and of replacing these components with modular, sectional "functional blocks11.
Each functional block may contain: a) Gas components and connections (burners, pipes, taps, supply ramps etc); b) Electrical components and connections (supply terminals, switches, commutators, connections for plates/ spark plugs, and other electrical control units); c) Mechanical components (universal joints, components for attaching the top, mobile components, bearing structure etc.); d) Decorative components (markings, decorations); e) Visual, acoustic or light-up display components (indicators, pilot lamps, buzzers); f) Final product identification components (marks, plates, symbols etc.).
Each block is thus entirely self-sufficient from both a mechanical and functional point of view, and can easily be associated with other blocks, or can be replaced by blocks which have similar connections and interfacing dimensions, but different types of performance or other dimensions or functions.
For example Figure 1 shows the two functional blocks 1 and 2. Their interfacing components are perfectly similar, although the features of their burners 3, 4, 5 and 6 are different.
Additionally each of the said burners has a supply duct 7, 8, 9 and 10 which is connected to a respective supply aperture 7a, 8a, 9a, lOa which is controlled by a corresponding tap 11, 12, 13 and 14, each of which is disposed, according to whether it is positioned to the right or left of the corresponding burner, on a lateral right or left ramp 15 or 16, as clearly shown in Figure 1.
The layout of these ducts 7, 8, 9, 10 is such that if the position of these blocks is inverted, obviously after the blocks have been turned round, the said supply ducts are disposed exactly in the position of the aforementioned supply apertures, except that this time the duct 7 is facing the aperture 10a, the duct 8 is facing the aperture 9a, and similarly for the ducts 9 and 10 of block 2.
If, as is logical, the type of connection between each duct and each aperture is the same, these blocks can replace one another if their positions are simply inverted after having they have been turned round accordingly, thus permitting maximum flexibility in the positioning of the individual burners.
This modularity is permitted by the aforementioned identical shape and interchangeability of the interfacing components, such that the final layout can be obtained immediately from the said interchangeable blocks.
It is clear from the above description that the shapes of the lateral blocks which bear the left ramp 16 and right ramp 15 and their respective taps, can be such that they can be correctly coupled either with block 1 or with block 2.
It will be appreciated that the invention can be used even more flexibly in cases where there are not just two central blocks and two end blocks as shown in Figure 1, but there is a plurality of central blocks, of which the interfacing features are fully interchangeable, but the burners of which mounted onto the said plurality of central blocks have different features.
Conversely, as shown in Figure 2, a simplified cooker top can be obtained, which is provided with a single functional block 20 of the type already described, disposed in the centre and bordered on one side by a ramp 21 of the above-described type, and on the other side by a component for delimiting and closing the cooker top.
The advantages of this solution will be apparent to a person skilled in the art: it will in fact be sufficient to produce a plurality of inner blocks of which the functional features differ, but of which the connection components are interchangeable, in order to obtain easily and economically a considerable number of types of cooker tops; this automatically eliminates the need to produce and store many types of cooker tops.
Additionally, production of the individual module and its assembly become repetitive operations which can easily be carried out by automatic processing systems. An advantageous variant of this structure consists of producing the said blocks and the said ramps from plastics material which is particularly resistant to high temperatures and deformation, and is now available on the market, using the most suitable technology.
This technique consists of simplifying and standardising further the structure of the components concerned, such that they can be obtained directly in a single piece.
Naturally, the principle of the invention remaining the same, the details of construction and forms of embodiment can be varied widely in comparison with those described and illustrated, without departing from the scope of the present invention.
