Definitions

  • the present invention refers to a gas burner arranged on a cooking hob for the heating of food contained in receptacles placed on it, and to a domestic cooking hob incorporating such burner.
  • Cooking hobs incorporating burners according to the known art although generally speaking efficient, have several drawbacks from the point of view of flexibility of use.
  • the fixed positions of the burners on the cooking hob causes problems for the simultaneous heating of two adjacent containers, when these are of medium or large dimensions: in such cases the containers therefore have to be arranged displaced from the central position on the relative burner, with understandable negative influences on the quality of the cooking.
  • the aims of the present invention is that of solving the aforementioned drawbacks and in particular to indicate a gas burner and a cooking hob of particularly flexible use, be it with respect to the types of containers to be heated, be it with respect to the available power and to its positioning.
  • FIG 1 a sectioned view of a burner is represented realised according to the details of the present invention, indicated as a whole with reference number 1; with reference number 10 a body base or sump is indicated, fixed to the lower part of a cooking hob P; the sump 10 has a gas supply duct, indicated with 11, that terminates in a nozzle 12, arranged substantially to the centre of the base wall of the sump 10. With reference number 13 two of four slots are indicated, obtained on the internal surface of the sump 10.
  • a removable body is indicated, or head, of the burner; the head 15 is also illustrated in figures 2 and 3, respectively seen from above and below.
  • a circular wall 16 elevates which, together with a central contour 17 and an upper flame divider element 18, defines a toroidal chamber 19; the flame divider 18, of the known type, has at least one series of passages for the exit of the air-gas mixture.
  • a mixture duct 21 is defined, which extends from the lower extremity to the upper extremity of the head 15, placing in direct communication the interior of the sump 10 with the toroidal chamber 19; as can be seen in figure 1, the duct 21 has a substantial inclination, that in the illustrated case is of approximately 45° with respect to the vertical axis of the head 15.
  • the axis X of the upper opening and the axis Y of the lower opening of the duct 21 are off-centred in a substantial manner from one another, which is not the case with burners of the known type.
  • a flanged part of the head 15 is indicated; as can be seen, in particular from figure 2, the circular wall 16, i.e. the zone which creates the flame crown of the burner, is not centred if compared to the flanged part 22 of the head 15.
  • the coupling of the head 15 of the burner together with the sump 10 is such to allow the presence of at least a gap, indicated with arrow A, through which the primary air necessary for the functioning of the burner reaches the interior of the sump 10.
  • the gas coming from the supply duct 11 in the known way reaches, through the nozzle 12, the interior of the sump 10; the primary air for the forming of the air-gas mixture penetrates the interior of the sump 10 through the mentioned gap, following the passage indicated by the arrow A.
  • the gas therefore begins to mix with the primary air, penetrates the mixture duct 21, where said mixture is completed, and then reaches the toroidal chamber 19.
  • the substantial inclination of the duct 21 has the important effect of improving the mixture of the primary air and gas; in fact, with equal dimensions in height with a burner of the known type, the burner according to the invention has a mixture duct having a length, or development, being substantially greater; it is therefore clear that the greater length of the duct 21 allows for obtaining a more thorough mixture of the primary air and gas.
  • the burner of figure 1 has a mixture duct which is longer by more than 30% if compared to a mixture duct that a burner according to the known art being of a similar height would have.
  • the burner 1 can be rotated so as to take on different working positions, being for instance of 90° one from the other; in figure 4 the burner 1 is in fact illustrated in which the head results in having been rotated 180° compared to that illustrated in figure 1 (in figure 4 the flame divider 18 is not represented).
  • a cooking hob equipped with the burner according to the invention guarantees a flexibility of use considerably improved if compared to those known, where the position of use of the burners is fixed.
  • Such cooking hob can also have two or more burners realised according to the aforementioned techniques and therefore each being able to take on at least two different positions; such burners would be arranged on said cooking hob in respective positions of such to allow the combined use with the aims of heating a single container of large dimensions, or the separate use with the aims of heating one or more containers of smaller dimensions.
  • the cooking hob incorporating the burner or burners according to the invention will be equipped with a grid, or with a system of a number or grids cooperating with each other, for simplicity not represented, realised so as to be able to support containers of different shapes and sizes, according to the cases (containers, of small, medium and large dimensions, square, rectangular, etc.).
  • the presence of the pins 20 and slots 13 assures the correct positioning of the head 15 on the sump 10, without risks of unbalancing the head; the presence of the pins and slots also impedes undesired separation of the head from the sump of the burner, that could occur in following occasional knocks.
  • the advantages of the invention mainly represented in the great flexibility of use of the proposed burner and of the relative cooking hob, be it from the point of view of the types of saucepans be it from that of the usable power, singularly or in combination; the described burner is in fact able to take on in relation to the cooking hob at least two different positions, in function with the type of container to be heated on said burner and/or in function of the container to be heated placed on a second burner of said cooking hob.
  • the burner according to the invention also has the advantage of allowing an improved mixture of the primary air and gas, due to the inclined position of the duct 21.
  • the burner could provide a pair of concentric burners each equipped with a relative mixture duct, i.e. an internal burner, apt at producing a central flame crown of reduced dimensions, and a peripheral burner, apt at producing two peripheral flame semi-crowns (see for instance the techniques described in the Italian Patent n. 1.232.887, in the name of the same Applicant). It is clear that, in keeping with the characteristics previously described a cooking hob realised according to the proposed variant has a flexibility of use being even further improved.
  • the burner described herein by way of an example could be, with simple perceptions, realised so as to withdraw the primary air from below the surface P of figure 1: for instance, instead of providing of the gap A and the sump 10, the head 15 could rest upon a sleeve element, equipped with seats 13 and also open towards the bottom, for the entrance of the gas coming from a nozzle arranged below and the primary air, thus withdrawn from below the cooking hob.
  • mixture duct apt at inducing a Venturi effect on the air-gas mixture could be of a form being different from that illustrated and described: in fact it is clear that while remaining with the off-centring of the flame divider and burner head compared with the sump, the mixture duct could be realised in another way.
