Definitions
- the present invention relates to a smoke and vapour-exhausting apparatus, in particular for cooking stoves, of the kind comprising the features recited in the preamble of claim 1.
- hoods or coverings disposed over the area where said smokes and vapours are produced may be provided, said coverings involving a natural or forced suction action by means of appropriate fans conveying all fumes towards a dicharge pipe or a flue.
- forced-suction collecting elements provided with filters is also known, said elements reintroducing the filtered air into the inner environment, which will present the use of exhaust tubes discharging the fumes to the surrounding atmosphere.
- Patent documents EP 521 810, EP 146 722 and DE-U-91 01 894 disclose each a vapour extracting hood provided with supporting and moving means adapted to enable said collecting hood to be selectively disposed for operation and varable-hight locations above the area where the smokes and vapours are produced.
- the technical task underlying the present invention is to provide a smoke and vapour-exhausting apparatus, in particular for cooking stoves, capable of substantially eliminating the above drawbacks.
- the technical task it is an important aim of the invention to devise an apparatus capable of upwardly drawing and evacuating smokes and vapours with the greatest efficiency.
- an apparatus for drawing smokes and vapours upwardly in particular for cooking stoves in accordance with the present invention, has been generally identified by reference numeral 1.
- Apparatus 1 comprises a collecting element for smokes and vapors 2, substantially defined by a hood, of the natural-suction type for example.
- the hood 2 is supported and made movable in a vertical direction by support and movement means 3 adapted to enable the hood 2 to be selectively located or operation, depending on requirements, at variable-height positions above the area where smokes and vapours are produced, said area being for example embodied by a cooking stove.
- Said heights can be selected within a predetermined range of minimum and maximum heights, as allowed by the support and movement means 3.
- a conveying pipe length 5 is located uppermost with respect to the hood 2 for receiving the fumes coming from the hood itself, which pipe length is slidably coupled to the inside of an end portion 6 of a discharge pipe 7.
- the longitudinal sizes of the pipe length 5 and end portion 6 are provided to be at least equal to the maximum stroke to be executed by the hood 2 so as to enable the latter to vertically slide between said minimum and maximum heights.
- the support and movement means 3 comprises a plurality of supporting cables 8, for example four in number (one of which is not discernible in the figure), engaged at one end thereof to the hood 2 and passing over idler pulleys 9 for example connected to the standards 10a of a cabinet 10 inside which the apparatus 1 is located.
- the supporting cables 8 are connected at their other end to one or more counterweights 11 suitably calibrated so as to balance the weight of the hood 2 and other components intergral therewith, thereby enabling the hood to keep a steady position at any height it is located.
- the idler pulleys 9 may be provided to rotate about axes parallel to the front face 2a of the hood 2 and each pair of cables 8 engaged at one side of the hood 2 may be connected to a single counterweight 11 which in this case will be located rearwardly of the hood itself.
- the idler pulleys 9 may have their own rotational axes directed perpendicularly to the front face 2a of the hood 2, so that the cable portions integral with the counterweights 11 are placed at laterally external positions with respect to the hood 2.
- each cable 8 will be provided with its own counterweight.
- the cables 8 and counterweight 11 can be arranged within appropriate boxes provided at the standards 10a.
- guide rails 12 are directed vertically and, for example, are integral with the standards 10a.
- coupling members 13 Engaged to the hood 2 are coupling members 13 to be slidably coupled to the guide rails 12, the shape of which matches that of said guide rails.
- Engaging elements may be also provided between the guide rails 12 and coupling members 13. They are defined for example by screw threaded pins 14a (only one of which is shown in the figure) to be screwed down across the guide rails themselves. Said threaded pins 14a, to be operated by respective working knobs 14, lend themselves to act against the coupling members 13 in order to cause fastening of the hood 2 to the desired work position.
- friction pads integral with the coupling members 13 may be provided and they are urged against the guide rails 12 by countersprings. The interference achieved by said friction pads must be appropriate to sustain the hood weight and the components integral therewith, while at the same time enabling said hood to vertically slide when a change in the height of same is required.
- a division element 15 designed to discretely route to the pipe length 5 all smokes and vapours collected in the hood 2.
- the division element 15 is internally comprised of a plurality of partitions 15a defining conveying channels 15b extending substantially parallel to one another.
- the conveying channels 15b are adapted to divide the overall fume flow collected in the hood 2 into a plurality of partial flows.
- a plurality of dividing webs 16 is provided to be disposed within the hood 2. Said dividing webs too form a plurality of conveying channels adapted to divide the overall fume flow into a plurality of partial flows, when the fumes are still in the hood 2.
- the support and movement means 3 enables the hood 2 to be quickly moved to the desired height and to be locked to said height. In this manner said hood 2 can be located closely spaced apart from the cookers and saucepans during the cooking steps. Vapours and smokes are therefore collected by the hood 2 substantially at the area where they are formed and any side escape of same towards the sourrounding environment is practically impossible.
- the presence of the division element 15 and/or dividing webs 16 within the hood 2 further helps in creating an unturbulent flow, thereby improving the natural suction capability of the hood 2 to a greater extent.
- the hood 2 can be moved upwardly exactly the indispensable distance by a mere manual operation and subsequently by another operation as quick and easy as the preceding one, it can be brought back to the lowered position, so that its suction capability will be completely exploited.
