Definitions

  • the present invention relates to improvements made to gas cooking appliances equipped with a top plate having at least one zone for fixing an injector of a gas burner and for supporting a head of said burner coaxially with said gas burner. injector and above said plate with primary air suction from the top of the plate.
  • the gas burner is surmounted by a grid, resting itself on the top plate and clean to support the containers with their bottom located at a given height above the burner.
  • the grid cast iron grate, wire mesh
  • the coming into contact of the flames with an element (finger, rod) of the grid leads to an increased emission of CO which can become excessive compared normative and sanitary requirements.
  • the object of the invention is therefore essentially to propose an improved arrangement of a gas burner of the type considered so that the correct positioning of the burner head no longer depends on the simple free will of the user, the means employed for these purposes, however, should not result in significant manufacturing complication or significant additional cost.
  • a cooking apparatus as mentioned in the preamble is characterized, being arranged in accordance with the invention, in that the aforesaid area of the top plate, whether integrally formed with the plate or that it is reported, has a non-circular contour and in that the legs, are in such number and are arranged in such a way that they cooperate with the sides of said non-circular contour of said zone so that the burner head can occupy only a determined and limited number of angular positions being simultaneously disposed coaxially with the injector and that for any incorrect positioning - in orientation and / or in centering - of the head, it rests on the top plate in an inclined manner and therefore visible.
  • said zone of the top plate is a non-circular plate surmounting the remainder of said plate, and the legs of the burner head are in number and have an arrangement adapted to their cooperation with the lateral faces of the plate. the non-circular pyramid bordering the plateau.
  • the provisions of the invention can also be implemented by ensuring that said zone of the top plate is a non-circular bowl extending under the remainder of said plate and that the legs of the burner head are in number and have an arrangement adapted to their cooperation with the lateral faces of the non-circular pyramid bordering the bowl.
  • a preferred embodiment, although not limiting, of the foregoing provisions is that the above area of the top plate has a polygonal outline.
  • a preferred embodiment of such an arrangement may consist in that said zone of the top plate is of rectangular shape and that the number of the possible correct positions of the burner head is two.
  • Another preferred embodiment of these arrangements may be that said area of the top plate is square in shape and that the number of correct positions possible of the burner head is four.
  • other configurations pentagonal zone, hexagonal, octagonal especially
  • the above area of the top plate could be elongated shape of revolution, including oval or elliptical, with obtaining the same benefits.
  • the arrangements according to the invention make it possible simultaneously to perform a physical foolproofing in the angular positioning of the burner head and its coaxiality with respect to the injector at the same time as they allow a simple visual control (burner head resting on crosswise on the top plate) in case of incorrect positioning (wrong angular positioning, coaxiality fault with the injector).
  • the means used are simple and practically without any impact on the manufacturing costs, since the conformation (flat, hollow or plateau) of the zone concerned of the top plate depends on the very design of the burner and the apparatus of the cooking and that the arrangement of the burner with primary air supply from the top of the plate involves the presence of legs: the implementation of the provisions of the invention is only relevant in the geometric form given to the aforesaid zone and in the geometric disposition of the legs in relation to the shape of the support zone.
  • FIG. 1 there is shown, very schematically, a sectional view of a gas cooking appliance of the type referred to by the invention.
  • the apparatus comprises a top plate 1 supported by two side walls 2, a bottom plate 3 which can be provided inferiorly to isolate the cooking appliance from an underlying part which can house another kitchen appliance.
  • the top plate supports at least one gas burner 4 (two burners are illustrated in FIG. figure 1 ) which are surmounted by a grid 5 for supporting a container.
  • the top plate 1 has a specific zone 7 in the center of which is fixed a gas injector 6 to which a gas supply pipe 10 is connected.
  • This specific area 7 may be integral with the top plate 1, or may also be reported on this plate.
  • each specific zone 7 protrudes above the top plate and is in its central part in the form of a plate 11 in the center of which is fixed the injector 6.
  • the head 12 of the burner 4 which is capped by a cap or lid 9.
  • the burner head 12 has orifices 13 distributed peripherally through which the flames 8 emerge.
  • Such gas burners are arranged in an extra-flat form and, in known manner, they are provided with a radial annular Venturi defined between the upper edge of a vertical central well 14 (visible at the figure 3 ) coaxial with the injector and the underside facing the lid.
  • a burner arrangement of the type considered is described for example in the document FR 01 05232 in the name of the Claimant.
  • the flame orifices 13 are distributed peripherally with discontinuities 15 (portions without orifices visible to the figures 1 and 4 ) facing the fingers of the grid 5.
  • the support of the burner head 12 at a correct height above the top plate 1 is also important for the definition of an appropriate annular gap between the lower edge of the burner head 12 and the plate. from above 1, the interval through which the primary air which is necessary for the operation of the burner and which, in this type of burner, passes through the top of the plate 1.
  • the burner head 12 must be arranged in perfect coaxiality with the injector 6 so that its operation is optimum.
  • this zone 7 can receive a polygonal or elongated shape of revolution.
  • the specific area 7 is polygonal of quadrangular shape, and more precisely rectangular, preferably with rounded corners.
  • the burner head 12 is equipped with supporting legs 16 arranged on a contour which is also quadrangular, and in particular rectangular, which has been materialized in the drawing by the rectangle 17 drawn in dashed lines.
  • the legs 16 are intended to contact the flanks 18 surrounding the rectangular plate 11 and, these flanks 18 being substantially inclined relative to the vertical, the legs 16 have a corresponding inclination.
  • it is advantageous to use six legs 16 as illustrated in FIG. figure 3 with two legs corresponding to the short sides of the rectangular outline and one leg in correspondence with the long sides of the rectangular outline.
  • the burner head 12 is positionable on the specific zone 7 with only two possible angular orientations mutually offset by 180 ° and with a correct coaxiality with respect to the injector, as illustrated in FIG. figure 4 .
  • legs do not all have the same height as illustrated in the figure 3 where two legs 16 has diagonally opposite are shorter than the other four.
  • each leg 16 (including the short legs 16 a) are in a generally L-shaped with a lateral bearing surface 19 is clean to cooperate with the corresponding sidewall 18 and a bottom surface 19b by which it rests on the plate 11.
  • the specific zone 7 may be in square form, with a square plate 11, in particular with rounded corners, while the legs 16 can be maintained six, be increased to a greater number, or be reduced to four, being arranged on a square outline.
  • Such an arrangement allows the positioning of the burner head indifferently in four angular orientations mutually offset by 90 °.
  • the specific zone 7 it is possible for the specific zone 7 to present a conformation that is the reverse of the preceding one, that is to say in the form of a bowl 20 with a polygonal contour (hollow pyramid) as illustrated in FIG. figure 6 .
  • the bowl 20 has a bottom 22 bordered by inclined flanks 21.
  • the burner head 12 is equipped with legs 23 of the same conformation as the legs 16 visible at the figure 3 , but reversed so that the staves inclined 23a can cooperate with the sidewalls 21 and that the horizontal surfaces 23b can bear on the edge of the plate 1 surrounding the bowl 20.
  • the bowl 20 may receive any desired polygonal shape for obtaining a required number of correct angular positions of the burner head 12.
  • the specific area 7 is not formed recessed or projecting on the top plate 1, but is simply coplanar with the plate 1.
  • the hollow impressions 24 which are arranged in a predetermined polygonal contour, contour that reproduces the positioning of the legs which is equipped with the burner head 12.
  • the hollow impressions are supposed to receive the ends of the legs 16 shown in the figure 3 and are arranged in correspondence.
