Definitions

  • the present invention relates to a burner device for hobs of gas cookers, of the type comprising a radiating body and means for conveying a combustible gas-air mixture to the ceramic radiating body.
  • gas cookers comprising burner devices each provided with a ceramic radiating body made up of microalveolate ceramic material: the ceramic body is made white-hot by combustion of the gas that is caused to flow therethrough by appropriate conveying means.
  • a plate of pyroceram material is provided to be disposed on the top of these ceramic-body burners, the sizes of said plate corresponding to the whole cooker hob and being adapted to form the rest surface of the food-cooking containers.
  • the technical task underlying the present invention is to conceive a burner device for hobs of gas cookers capable of substantially obviating the mentioned drawbacks.
  • a burner device for hobs of gas cookers which is characterized in that it comprises a holding and support body having a housing seating for receiving said radiating ceramic body, and a plate-like element associated with an upper portion of said holding and support body to define a rest surface extending above the radiating ceramic body.
  • the burner device for hobs of gas cookers is generally identified by reference numeral 1.
  • the radiating body 4 may consist of a substantially laminated or flat element made of metallic or synthetic fibres.
  • the metallic or synthetic fibres may form a laminated-texture fabric or mat depending on requirements.
  • the holding body is such shaped and sized that it can completely house the radiating body inside it.
  • the radiating body shape will be the same as the shape to be given to the ring, a circular shape for example depending on requirements, and said radiating body will be housed in a holding body conforming to it in shape. More specifically, the holding body 2 has a base from which a side wall perimetrically surrounding the ceramic body emerges.
  • the holding and support body 2 further has an upper portion 5 comprising an annular seating 5a adapted to house and engage a preferably plate-like rest element 6; advantageously and preferably the rest element may be made of pyroceram; element 6 defines a rest surface for a food-cooking container that can be disposed over the radiating body 4.
  • the extension and shape of the rest element 6 substantially correspond to those of the underlying radiating body 4 and said element closes the burner device 1 on top.
  • the upper portion 5 comprises at least one opening 5b for burnt gas evacuation, which is disposed between the annular seating 5a and housing seating 3 for the radiating body 4. It is to be pointed out that opening 5b extends above the ideal plane defined by the upper surface of the radiating body 4 and below the rest element 6 or flush therewith.
  • slit-like openings 5b disposed under the plate-like element 6 and extending in the upper portion of the side wall of the holding body 2, above the lying plane of the radiating body.
  • the distance between the lying plane of the ceramic body and the lying plane of the plate-like rest element is selected for the purpose of optimizing combustion and outflow of the burnt gases.
  • the distance between the upper surface 4b of the radiating body 4 and the lower surface 6a of the rest element 6 is included between 5 and 25 mm and preferably between 10 and 20 mm.
  • the gas-air mixture is sent to the lower face 4a of the radiating body 4 by conveying means 7 formed in a lower portion 8 of the holding and support body 2 itself.
  • the conveying means 7 preferably comprises at least two independent mixing chambers 7a, 7b, disposed below the ceramic body 4 and each adapted to convey the gaseous fluid to a corresponding portion of said ceramic body.
  • the radiating body 4 has a substantially annulus-like plan conformation and the mixing chambers 7a, 7b have annular concentric shapes each corresponding to an outer portion and an inner portion respectively of the annulus-like shape of the radiating body 4.
  • annular seals 9 are interposed between the upper edge of said chambers and the lower face 4a of the radiating body 4 to ensure permanence of the gaseous fluid in the respective mixing chambers.
  • control and regulation unit 10 possibly also provided with electronic components is connected with each burner 1 and it is adapted to offer the user the possibility of an independent control of the gas flow in the mixing chamber or chambers 7, 7a, 7b.
  • a user can choose, depending on requirements, whether he/she wishes to have at his/her disposal a narrow radiating surface corresponding to the inner mixing chamber 7b, a larger radiating surface corresponding to the whole annulus defined by the radiating body 4, or even a radiating surface only corresponding to the outer mixing chamber 7a.
  • the user can choose among a greater number of radiating surfaces of differentiated extensions for each burner device.
  • the radiated thermal flow can be also varied in each corresponding region of the radiating body; i.e. it is possible, for instance, to have a hotter radiating surface in the outer band than in the inner band or vice versa, to meet particular cooking requirements.
  • a hob 11 Shown in Fig. 5 is a hob 11 provided with four burners or rings of at least partly different diametrical sizes, each of which consists of a burner device 1 corresponding to the above description.
  • the hob thus made enables many advantages to be achieved, resulting from the particular features of each burner device.
  • the device is very versatile and of high yield, because the user can manage each burner device in an independent manner, so that the radiating surfaces are as much as possible close to the bottom sizes of the containers to be heated.
  • the hob surface can house several rows of burner devices, like in traditional cookers, because each burner has opening for exhaust of its own burnt gases: thus these gases neither interfere with the other burners nor can be stored, as in the known art, under a single pyroceram plate covering the whole hob.
  • a hob provided with burners devices in accordance with the invention can be easily obtained by replacement of the radiating gas burners or electric plates present in traditional cookers and consequently specific planning and constructions are not required.
  • the burner devices having a radiating body can be shaped following any conformation, instead of having a traditional circular form, for the purpose of meeting the most varying operating and/or aesthetic requirements.
