Definitions

  • the present invention relates to the use of a domestic gas burner, of the type comprising a burner base and a burner head provided with at least one flame crown, in a cooking hob having a supporting surface made of a material that is physically and/or only structurally degradable in the presence of heat sources, such as, for example, tempered glass.
  • heating hob is meant, in what follows, any installation for the cooking of foodstuff provided with a support for housing at least one burner designed for supplying heat to the foodstuff itself, comprising in this term installations such as, for example, surfaces equipped for cooking or cooking ranges.
  • tempered glass a material which, in its most typical compositions, poorly withstands temperatures higher than 280° C., is in any case more desirable in so far as tempered glass is able, from the aesthetic standpoint as well as the maintenance standpoint, to replace pyroceram, the use of which in cooking hobs entails extremely high costs.
  • cooking hobs having a supporting surface made of pyroceram is, in fact, particularly widespread on account of its aesthetic qualities and the simple cleaning operations that such cooking hobs require.
  • the cooking hobs made of said material do not present any structural or mechanical degradation to thermal stresses coming from the burners, even though they prove particularly expensive and difficult to model.
  • Said solution which entails the use of metal plates having a plan extension that is other than negligible, is able to prevent fractures in the cooking hob, but is aesthetically far from pleasant and constitutes an obstacle to cleaning of the cooking hob.
  • such metal plates may be shaped like concave containers or trays, at the centre of which is housed the burner. This implies the drawback of accumulation of grease and ashes in the plate, with consequent inconvenience for cleaning of the cooking hob, as well as the need to achieve a considerable precision of fabrication and of assembly of the plates, which need to have low dimensional tolerances, as compared to the specific techniques envisaged in the design phase.
  • gas burners used with said protective plates are generally of the type in which the intake of primary air takes place underneath the cooking hob, given the overall dimensions of the protective plate itself and the laborious problems involved in making air-inflow inlets set above said plate.
  • Gas burners in which the flow of primary air for combustion comes from underneath the cooking hob are less efficient and usually of larger dimensions as compared to burners in which the primary air is taken in above the cooking hob and likewise involve the presence of appropriately designed air intakes in the supporting surface, which, above all in brittle materials, such as tempered glass, can prove difficult to produce.
  • cooking hobs with a supporting surface made of stainless steel or other materials that are structurally resistant to heat but aesthetically degradable, such as enamelled steel, said cooking hobs tend, in the proximity of the burners, to undergo deformation and to change colour permanently, thus rendering the cooking hob itself somewhat unpleasant from the aesthetic point of view.
  • the present invention provides a surprising solution to the drawbacks that arise with the use, for the supporting surface in cooking hobs comprising one or more atmospheric gas burners, of materials that are physically and/or only structurally degradable when set in the presence of heat sources.
  • a purpose of the present invention is to provide a cooking hob having a supporting surface for housing the burners which is made of a material that is degradable in the presence of thermal emissions, which does not present the drawbacks referred to above, and at the same time is of pleasant appearance and simple to produce and maintain.
  • Another purpose of the present invention is to provide a cooking hob having a support made of a material that is degradable in the presence of thermal emissions and is provided with at least one gas burner, in which the latter is of the type that envisages the inflow of primary air from above the support that houses the burner itself.
  • the solution to the drawbacks referred to above can be achieved by using, in a way that is unknown to the prior art and is in itself surprising, a gas burner of an atmospheric type provided with a burner base, a burner head having at least one flame crown, and a circumferential ring, the gas burner being set in a hole made in the supporting surface of a cooking hob which is made of a material, the physical characteristics or the structure of which are degradable in the proximity of heat sources.
  • the circumferential ring is set between the flame crown and the supporting surface.
  • the action of the circumferential ring is that of shielding the latter from the irradiation coming from the burner and from the heated recipient, in order to prevent, in the proximity of the said burner, there being formed temperature gradients such as might cause fracturing of the said supporting surface.
  • the circumferential ring also has the function of dissipating the heat transmitted by irradiation and by conduction along the burner.
  • the circumferential ring is separate from the support of the cooking hob in such a way that the space existing between the support and the circumferential ring will enable passage of the primary air directed to the burner, this implying the use of a burner of the type in which the primary air is taken in above the cooking hob.
  • the primary air inflow which is drawn, for example, by a horizontal Venturi tube (also known as radial Venturi), with which the burner can be equipped, contributes to cooling down both the circumferential ring and the supporting surface in the proximity of the burner.
  • a horizontal Venturi tube also known as radial Venturi
  • the circumferential ring has a plan diameter greater than or equal to the diameter of the hole within which the burner is housed and preferably greater than or equal to the diameter of the flame crown.
  • the burner is of the type comprising two or more flame crowns, and the supporting surface is made of tempered glass.
  • the present invention also intends to protect a cooking hob which has a support made of a material, the physical characteristics of which or the structure of which are degradable in the proximity of heat sources, and provided with at least one hole, within which is housed, at least partially, a gas burner of the type comprising a burner base and a burner head with at least one flame crown.
  • a gas burner of the type comprising a burner base and a burner head with at least one flame crown.
  • Said burner is provided with a circumferential ring set between the flame crown and the supporting surface.
  • the circumferential ring is set at a distance from the supporting surface, and the primary air is taken in above the supporting surface and underneath said circumferential ring.
  • the present invention relates, with reference to FIG. 1 , to the use of at least one gas burner 2 , 3 a , 3 b or 3 c with one or more flame crowns in a cooking hob, for example, a domestic cooking hob, provided with a supporting surface 1 made of a material the physical characteristics of which or the structure of which are degradable in the presence of heat sources, such as, for example, tempered glass, stainless steel, or enamelled steel.
  • the present invention likewise relates to a cooking hob having a supporting surface made of a degradable material.
  • FIG. 1 illustrates, then, purely by way of non-limiting example, a cooking hob provided with a supporting surface 1 , for example, made of tempered glass, on which are arranged, in purposely provided seats, a burner 2 with three flame crowns and three burners 3 a , 3 b , 3 c having just one flame crown.
  • the burner 2 comprises, according to the present invention, a burner base 4 and a burner head 5 bearing the above-mentioned three flame crowns, as well as a circumferential ring 9 set between the flame crowns and the supporting surface 1 .
  • the outermost flame crown, defined in the burner head 5 by peripheral holes 26 , can be seen in FIG. 2 .
  • the base 4 of the burner 2 is housed in a circular hole made in the said supporting surface 1 (and set in a position corresponding to the portion designated by 22 in FIG. 2 ), supported by a plurality of flat springs 8 set opposite to a circular flange 7 , between which is set the portion of the supporting surface 1 adjacent to the housing hole.
  • the burner 2 is likewise provided with a supporting grill 6 for a cooking container.
  • the burner 2 comprises a base 4 set underneath the supporting surface 1 , which is made of tempered glass, in which there is set an injector 23 for the combustible gas.
  • the base 4 presents peripheral ramifications or projections 24 , which engage in the seat of the supporting surface 1 and carry both the flange 7 and the flat springs 8 .
  • the coupling of the springs 8 to the circular flange 7 and the mutual clamping thereof, after prior interposition of the edges of the housing hole of the burner 2 enables stable fixing of the burner base 4 to the supporting surface 1 .
  • the base 4 of the burner 2 can be housed in a circular hole of the supporting surface 1 , without coming into contact with the latter and being supported, for example, by elastic means, on a structural element of the cooking hob set underneath the supporting surface 1 and not visible to the user.
  • a burner head that has a central body 12 , closed by a top lid 10 and equipped, once more according to the prior art, with a horizontal Venturi tube (or radial Venturi) 11 for mixing of the gas with the primary air, and with a distribution chamber having holes facing outwards and designed to define a first central flame crown.
  • the burner head further comprises a toroidal body 13 , which is surmounted by a an annular lid 14 and connected to the horizontal Venturi 11 and/or to the distribution chamber of the body 12 by appropriate radial channels (not illustrated), and which presents an inner series of holes and an outer series of holes designed for defining, respectively, a second flame crown and a third flame crown.
  • the second flame crown is, in particular, set in opposition to the first central flame crown, and the burner 2 is moreover provided with a grill 6 designed for supporting a cooking container.
  • the burner 2 is of the type in which the primary air I is taken in, thanks to the suction exerted by the Venturi 11 , from above the supporting surface 1 , penetrates, via channels (not illustrated), into the chamber defined by the burner base 4 , and then is mixed with the gas coming out of the nozzle 23 in said horizontal Venturi (or radial Venturi) 11 .
  • a burner of the type referred to above is known from the patent application EP-A-0.903.538 or from the publication EP-A-0.797.048, both of which are in the name of the present applicant.
  • the burner 2 likewise presents a circumferential ring 9 , which is made of the same material as or of a material different from that of the burner, set coaxial to the vertical axis of the said burner and set between the flame crowns and the supporting surface 1 made of tempered glass.
  • the ring 9 is separate from the supporting surface 1 , and the primary air I is induced to enter the burner above the supporting surface 1 and underneath the ring 9 .
  • circumferential ring 9 which is conveniently set between the heat source, represented by the flame crown or flame crowns, and the supporting surface made of tempered glass, enables adequate shielding of the supporting surface made of tempered glass 1 from the irradiation coming from the flame crowns and, albeit to a lesser extent, also from the irradiation coming from the heated cooking container.
  • the above-mentioned shielding action which brings about lowering of the temperature of those areas of the supporting surface 1 in the proximity of the burner 2 , has surprisingly proved sufficient for preventing the substantial degradation of the material of which the supporting surface 1 is made.
  • the interposition of the ring 9 prevents the generation of fractures and makes possible the use of said economic material in the production of cooking hobs.
  • the ring 9 has enabled reduction or elimination of the formation of halos or deformations of the supporting surface 1 .
  • the contribution of the flow of primary air I in the action of local cooling is deemed particularly important, albeit not essential, in the case of brittle materials, such as tempered glass.
  • the ring 9 acts also partially as a heat sink, by conduction, of the heat produced by the burner 2 itself, thus lowering the temperature of the latter in the proximity of the said ring 9 and, hence, the temperature in proximity of the hole housing the burner in the supporting surface 1 .
  • the plan diameter of the circumferential ring 9 is greater than the diameter of the hole present in supporting surface 1 made of tempered glass and is also greater than the plan diameter of the outermost flame crown defined by the toroidal body 13 .
  • the ring 9 extends, in plan view, from the burner base 4 , or from the burner head 5 , up to beyond the flame crown made along the outer perimeter of the toroidal body 13 .
  • the above dimensions of the ring 9 which are much greater than the dimensions of similar rings made in burners provided in traditional cooking hobs, enable an effective shielding of the supporting surface underneath.
  • the ring 9 is moreover preferably shaped substantially like a truncated cone with the major base facing the supporting surface 1 so as to prevent any possible residue of food that may come out of the cooking container from getting stuck on the ring 9 , with the risk of combustion thereof.
  • Alternative embodiments of the ring 9 made with a convex shape have proven equally effective.
  • the circumferential ring 9 may be made separately from the burner 2 and coupled, by juxtaposing the various parts, to the latter, but may also be made integrally with an element of the burner 2 itself.
  • the ring 9 be coupled to a burner of the type described in EP-A-0.797.048, i.e., a burner, which comprises an inner metal plate shaped for separation of the fluid flows, said ring 9 may be made of a single piece with said inner metal plate, thus considerably simplifying its production.
  • Materials that may be suitable for the production of the ring 9 are steel, aluminium alloys (Al—Si or Al—Ni), or other alloys or metal materials, such as brass, or else ceramics or plastic technopolymers with ceramic fillers or with fibre fillers that are resistant to high temperatures.
  • FIG. 4 illustrates another embodiment of the present invention, in which, on a cooking hob provided with a supporting surface 1 made of a thermally degradable material, there is fit an atmospheric gas burner 3 of the type comprising just one flame crown.
  • the burner 3 comprises: a burner base 15 fit in a housing hole made on the supporting surface 1 ; elastic means for coupling to the supporting surface 1 , which consist of one or more flat springs 21 and a circular flange 20 for being set opposite to said springs; a burner head 16 ; and a top lid 17 .
  • the base 15 is withheld in position thanks to the interposition of the edges of the hole for housing the supporting surface 1 between the spring 21 and the circular flange 20 and comprises a chamber, within which there is present an injector 23 , fluid-connected to a pipe 25 for supplying the combustible gas.
  • the burner head 16 of the burner comprises a horizontal Venturi 18 , constituted, according to the known art, of a reduced section portion and of a radial expansion chamber, and is enclosed by the lid 17 .
  • a horizontal Venturi 18 constituted, according to the known art, of a reduced section portion and of a radial expansion chamber, and is enclosed by the lid 17 .
  • At the radial ends of the expansion chamber there is a portion for distribution of the gas-primary air I mix, which presents a series of holes that form the flame crown of the burner 3 .
  • the burner 3 likewise presents, connected by interposition of parts, a circumferential ring 19 , which extends from the burner head 16 of the burner up to beyond the flame crown.
  • the said circumferential ring 19 is separate from the supporting surface 1 in order to enable inflow of the primary air I between the said supporting surface 1 and the ring 19 .
  • the effect of shielding from irradiation and of cooling of the supporting surface 1 by the flow of the incoming primary air I obtained thanks to the ring 19 , enables the use of cooking hobs provided with supporting surfaces made of thermally degradable materials, such as, for example, tempered glass, stainless steel, or enamelled steel.
