Definitions

  • the present invention relates to improvements brought to multiple crown gas burners of flames which are suitable for mounting on a plate above a cooking appliance, especially for use household, and which include a first central burner, having a ring of peripheral flames and minus a second burner, annular and surrounding at a distance the central burner, having at least one crown of flames.
  • Such burners are used when a significant heating power is required and / or, conjunction with respective supply devices gas from the central and ring burners, when a modulation of the heating power, in location and in time, is required (Asian cuisine by example).
  • crowns of flame provided with a central burner at one crown of flames and an annular burner provided with a outdoor flame crown or two crowns of flames, respectively interior and exterior.
  • the invention therefore aims to provide a burner with multiple flame crowns of an improved type, whose structure is suitable to confer a level of modern security while remaining simple to manufacture with a number of component parts reduced to a minimum, and in addition with a relatively vertical development reduced allowing its installation as well on a conventional stove only on a hob.
  • a multiple flame crown burner in which the all of the primary air required to operate the first burner, central, and second burner, annular, is brought respectively to the vicinity of the first and second gas injectors via paths located exclusively above the top plate of the appliance cooking; for this purpose, the primary air enters the annular space defined between the burner head outside and the top plate, cross the recesses side of the burner head support means outside and enters the burner body where it is mixed with the gas jet leaving the first injector feeding the central burner, while otherwise passes from said annular space directly above, by a side opening provided for this purpose, towards the entrance of the horizontal convergent-divergent duct where it is mixed with the gas jet leaving the second injector to the external burner supply.
  • this secondary air is partly constituted by the ambient air surrounding the burners (crown of flames outside of the second burner, annular; crown of first burner, central), partly by a fraction of the air entering the annular space defined by the external burner head and the plate above, this fraction of air passing through the aforementioned lights, between the two central burners and annular and feeding the crown flames inside of the annular burner and, in part, the central burner flames.
  • the burner with multiple crowns of flames with structural arrangements specific to provide air supply, primary and secondary, leading to preventing a repercussion of uses underlying parts of the cooking appliance on the flames, even at low speed, in other words to prevent a possible flame extinction, especially at low regime, during a violent closing of the door of a including the underlying oven.
  • the horizontal Venturi arrangement for the supply of the external burner head and the Venturi directed upwards and formed, as shown further on, partly tubularly and partly radially horizontally, provides a burner of relatively low height suitable for mounting also well on a stove than on a hob.
  • the central well of the interior burner head is directed substantially vertically and the axis of the first injector is substantially vertical.
  • the central well of the burner head is expected interior and the first injector which is substantially thereto coaxial are inclined by about 15 to 20 ° relative to the vertical.
  • the gas burner has a single annular chamber in the external burner head, which is bordered bilaterally by passages of flame, and that the second burner, annular, has two crowns of flame, the burner being of the three flame crown type.
  • the support means of the external burner head are integral with said head of external burner and are constituted in the form general of a skirt projecting below under the below said head and a surrounding shoulder the central recess of the central region of said head burner.
  • the annular chamber of the external burner head can be closed, top, by a removable annular cover placed on the side walls of the room.
  • the first burner, central either with a long Venturi sufficient, that the central well of the burner head interior has a decreasing section in direction from the top, thus forming a first section of Venturi, tubular, and that the upper surface of the head interior burner surrounding the upper orifice of the well central define, together with a cover removable above it, a radial annular divergent forming a second section of Venturi, annular radial.
  • the burner has a flame detection thermocouple and / or a electric ignition member and said thermocouple and / or ignition device are functionally associated with central burner.
  • a burner arranged in accordance with the invention presents, thanks to its structure, a great flexibility according to the type of cooking appliance to equip.
  • the external burner head can, depending on the case, be provided with a single crown of flames arranged either internally or externally or be provided with two flame crowns indoor and outdoor.
  • the burners central and exterior can, depending on the case, either be connected to a common gas supply control, either be connected each to an individual control gas supply, which allows modulation flexible heating conditions in location and in time.
  • the gas burner of the invention has a burner head interior 1, which is in the central position, having a peripheral flame crown (flame passages 2) and at least one external burner head 3, which is annular and remotely surrounds the central burner head 1, having at least one inner ring of flames and / or outdoor.
  • the external burner head, annular, 3 has two flame crowns, one inside (flame passages 4) and the other exterior (passages of flames 5).
  • the burner further includes a burner body 6 partially visible in Figures 1 and 2 and shown in isolation in FIG. 3.
  • This burner body 6 has here a relatively elongated shape, substantially in correspondence with the diameter of the burner head exterior 3 which overcomes said body.
  • the burner body 6 is designed to be fixed, by fixing means 7, under the top plate a cooking appliance, such as a stove, which top plate P is visible on the sectional drawings Figures 5, 6 and 7.
  • a first gas inlet 8 connectable to a gas supply via control means (not shown) which are preferably their own.
  • the gas supply 8 is in communication with a gas injector 9 located coaxially opposite one end of a conduit 10 first converge, then diverge and form Venturi tubular, which extends substantially over the largest part of the length of the burner body 6, i.e. the diameter of the outer burner head 3. Between the gas injector 9 and the conduit 10 is a light 11 for primary air intake. At its end terminal, line 10 is connected to a well substantially vertical 12 bringing the air-gas mixture into the external annular burner head 3.
  • the burner body has a second gas inlet 13 distinct from the aforementioned first arrival 8, and arranged, here on the side of the body 6.
  • the gas inlet 13 is connectable to a gas supply via means of controls (not shown) which are specific to it and are separate from the power control means of the first gas supply 8.
  • the gas inlet 13 is in communication with a gas injector 14 which is directed upwards: at the Figure 6, the axis of the injector 14 is substantially vertical and substantially coaxial with the burner heads inside 1 and outside 3.
  • the body of burner 5 supports accessories necessary for safe operation of the burner, and in particular at least a thermocouple Th and at least one ignition member electric Al.
  • the external burner head 3 rests, through a cutout 30 made in the top plate P, on the burner body 6 by means of support.
  • the burner body 6 has a support flange 16 overall circular located centrally and coaxially to the vertical injector 14.
  • This flange 16 forms with the central bottom of the burner body 6 a kind of tank, having the injector 14 in its center and the means of outside burner head support arranged laterally.
  • the means of support are secured to the underside of the burner head outside 3 and are formed in the form of a skirt 17 protruding downwards outwardly forming a peripheral shoulder 18 bearing on the top of the flange 16 above.
  • This skirt 17 is made either of continuously with lights, either so discontinuous (case illustrated in Figure 6) in order to build 20 primary air passages like this will appear later.
  • the lower edge of the skirt 17 is shaped to cooperate with projections 19 provided in the bottom of the tank, so as to block in rotation of the external burner head 3 on the body of burner 6 and serve simultaneously to position them mutually angularly correctly.
  • the part of the external burner head 3 which surrounds the central region provided with the projecting skirt 17 overhangs the top plate P while being kept at a distance above of it, so the top plate P and the face bottom of burner head 3 define them an annular space 21, of irregular shape having regard to the general conformation of the burner.
  • the aforementioned passages 20 communicate with this space 21.
  • the external burner head 3 has a annular chamber 22 located near the periphery external of this head.
  • Chamber 22 is formed by a channel defined by a bottom 23 and two side walls concentric 24, 25 and by a cover or cap annular 26 covering said channel.
  • walls 24, 25 are formed notches forming flames.
  • the two walls 24, 25 are provided with respective notches 4, 5, so that the outer burner head has a double crown of flames.
  • the bottom 23 has an opening 27 facing the well substantially vertical 11 above.
  • annular cap 26 is guided during its installation, and held in position by positioning fingers 28 integral with the external burner head 3.
  • the head of external burner 3 is arranged so that between a central region which will be discussed below and the annular chamber 22, it has lights 29 which open this intermediate annular zone, for the purpose to allow air circulation as it will appear further.
  • the central region 31 of the burner head outer 3 has a substantially vertical recess 32, coaxial with the axis of the injector 14.
  • the central burner head 1 is supported peripherally on an annular shoulder 33 practiced in the external burner head 3. Its central region, projecting downwards, is engaged in the recess 32 above of the external burner head and has a central well 34 coaxial with the axis of the injector 14.
  • the well 34 has a decreasing upward section and forms a convergent.
  • the peripheral wall 35 of the burner head central 1 is pierced with notches 2 forming passages of flames.
  • a cap or cover 36 rests on the wall 35.
  • the facing faces of the cover 36 and the central region of the central burner head 1 which surrounds the orifice of the well 34 deviate substantially from each other radially outward, forming a radial annular divergent 37.
  • the entire convergent tubular 34 and radial annular divergent 37 constitutes a Venturi.
  • Figure 7 is shown a variant of realization of the arrangement illustrated in FIG. 6 and in which the central well 34 and the injector 14, coaxial, are no longer vertical, but tilted at an angle of 15 to 20 ° from the vertical.
  • This arrangement is preferred in the vertical axis assembly of Figure 6, due to the elongation provided for well 34: although low, this extension is sufficient to improve the efficiency of the burner central 1.
  • the external burner head 3 is, as is often the case for burners with gas, bordered below by an annular skirt device 38 inclined downwards.
  • This skirt can be integral part of burner head 3 as visible in particular in FIGS. 5, 6 and 7, or else may be a annular part 39 removably attached to the head burner 3: this annular part 39 can be put in place thanks to appropriate shoulders as illustrated, in partial sectional representation, in Figure 8.
  • it then becomes easy to conform and / or decorate this annular part in various ways in order to satisfy for example business requirements.
