Definitions
- the present invention relates to a hearth gas cooktop made of three pieces totally dissociable mechanical in which the support grid for cooking vessels is used for flame stability.
- a stove or table burner gas cooking traditionally consists of a monobloc burner body, flat or domed cap placed on the upper end of this body and a support grid which carries the cooking vessels.
- the lateral surface of the part forming the cap is through a multitude of gas outlet ports arranged in a crown to give birth to elementary flames which, joined together, constitute the burner flame.
- This grid constitutes a unit separate functional.
- the burner must be protected culinary products that may spill containers and projections of all kinds.
- additional support of protection for example plate-shaped, surrounds the base of the burner.
- Document EP-0 123 007 describes a gas fireplace where a plate forming the grid is stabilized and fixed on the hob.
- Document DE-1 127 061 describes a gas fireplace where the base and the support grid forms an integral assembly comprising seven parts.
- Document FR-2 369 504 describes a gas fireplace where the flue angled is screwed directly into the base.
- the crown of flames must be tightened, i.e. brought back towards the exit orifices by as many concentric forces as necessary.
- a first technique consists in using a burner whose path initial of the flames is directed upwards then to fold down the crown of flames down by an upper cover with a peripheral rim forces the flames to curve down before developing radially.
- Another technique used is to create a so-called flame pilot. It is a secondary flame of small power arranged also in crown and arising below the flame main.
- This pilot flame can exist thanks to an interval additional gas outlet located in the burner head immediately under the main flame crown in the adjacent side wall.
- the pilot flame interval is that between the underside of the cap of the burner and the upper front end of the cylindrical central projection of the base. This interval is obtained and maintained by spacers shaped in the underside of the cap by which the burner is supported on the upper front face of the base. the height of these spacers determines the width of the corresponding slot.
- the base must remain fixed because it ensures, on the one hand the contact mechanical with support and support elbow support by a closing piece and on the other hand the sealing.
- the cylindrical central projection of the necessarily fixed base can decrease in height and thus provide greater ease of cleaning using the rim of the central part of the grid for the creation of the interval giving birth to the pilot flame.
- the object of the present invention is to generally eliminate the disadvantages above and allow the serial production of burners to three pieces with pilot flame, especially those in which the base is as flat as possible by using the support grid in association with the burner head to constitute the outlet slot of the pilot flame.
- two of the parts namely the support grid and the head of the burner are fitted coaxially one on top of the other and the grate has an upper rim in extension of its central part, rim whose upper front face is used as the lower wall of the pilot flame creation slot.
- the invention relates to a gas fireplace for The hob or gas stove according to claim 1.
- the invention provides particularly advantageous advantages linked to the constitution of the home in three parts including the burner body and the grate are separable from the base. So cleaning the cooking plan is further facilitated.
- the cleaning of the fireplace cannot be more simple: just dissociate the component parts to free up sufficient space around the base to conveniently clean the entire area visible around the burner.
- the grate and the burner head easily and completely dissociated from the base can be individualized and cleaned or washed separately, for example in a household appliance dishwasher like any other cooking utensil.
- the gas fireplace for cookers or tables cooking, for example domestic cooking consists of a base and two other parts totally, quickly and easily dissociable, know a support grid and the burner cap.
- the central part of the support grid of the fireplace is used as one of the means, with the underside of the burner head, to create the so-called flame pilot, i.e. the lower annex flame allowing to hang the main flame.
- the components of the fireplace according to the invention is mounted on a cooking surface 1 completely flat from a hob or cooker.
- This plan shows a passage 2 for a elbow supply connection 3 providing the mixture combustible gas at the burner.
- This elbow 3 emerges from the upper face by a straight section 4.
- the base has a peripheral shoulder double 8 extended upwards, for the first mode of execution, by a hollow cylindrical section and coaxial 9 terminated by a flat annular front face 10.
- the flat head 7 has on its side face a peripheral succession of individualized slots such as 11 arranged in corresponding crown each at the exit of a flat sheet flame.
- the head is extended downwards by a 12 smaller cylindrical lower projection diameter whose birth delimits a shoulder 13 surrounded by a flat border 14 on the underside of which emerge from the thicknesses playing the role of spacers (not shown) for cleaning with a ledge peripheral opposite a free interval 15 below of the crown of the slots 11, interval necessary for the creation of the flame (s) pilot (s) or hooking the main flame.
- the head 7 is simply placed on the base 5 and can therefore easily dissociate from it.
- This burner is completed by a support grid 16 with four branches such as 17 comprising a central part 18 in a crown, the edge of which has a profile 19 complementary to that of the shoulder of the base coming to be placed by fitting and wedging support on the double shoulder of the base.
- the branches have curved radial legs such as 20 tangent from the central crown 18 providing the whole with a twisted or volute.
- the upper parts 21 in L of these branches, are of classic technical form for the support for cooking vessels.
- the base 5 is removably mounted or secured to the cooking surface 1 via bindings such as 22 bringing it together across the plane 1 to a lateral extension or neck 23 of the elbow 3 (figure 8).
- the double peripheral shoulder of the base 5 on which is fitted and rests in place the inner peripheral edge of the central part 18 of the support grid 16 has a complementary profile to that of said grid, that is to say for the example shown, a conical ramp 24 followed by a right shoulder 25.
- the complementary profiles of these edges can have different shapes, for example example that of a straight shoulder with or without stop allowing a cylindrical fitting simple or any other form of profile ensuring fitting and wedging.
- the base 5 affects a general circular flat shape. It presents a outer conical shoulder 26 and a central disc 27 slightly protruding, delimiting between its outer circular edge and the ledge conical outer device 26 an annular range support 28.
- This head present on its face lateral a peripheral succession of orifices circular or individualized slots 11 each corresponding to the exit of a flame elementary according to the shape of a dart or flat according to a tablecloth, each intended to constitute a crown of radial flames or a corolla.
- the head 7 is extended downwards by the 12 smaller cylindrical lower projection diameter whose birth delimits the shoulder 13 surrounded by the flat edge 14 of the underside, of which emerge the extra thicknesses playing the role spacers (not shown) to spare with a peripheral edge opposite an interval free 15 necessary for the creation of the flame (s) pilot or hooking the main flame.
- the burner body rests in support by the lower front face of the cylindrical projection 12 of the burner on the central disc of the base 5 and can so easily dissociate from it.
- the fireplace is completed by the support grid 16 which includes as before four branches 17 of the same type comprising a central part 18 in a crown the lower edge of which has a profile complementary to that of the double shoulder peripheral device of the base 5 to come place by fitting and wedging on the edge external device and the annular range of the base 5.
- the support grid 16 further comprises, at the end upper part of its central part 18, a rim upper peripheral raised, for example narrow, 29 straight and with flat upper front face 30.
- This rim is arranged in coaxial alignment with the side face cylindrical lower part of the central part interior.
- a narrow rim 29 in circular rib with square or rectangular section extending towards the bottom by a recess 31 recessed inward followed by a steep conical ramp 32 constitutes a example of suitable technical forms.
- the upper front face 30 is machined from so as to be perfectly flat. It is arranged in look of the underside border 14 of the head 7 of the burner to be used for the creation and maintenance of the interval 15 giving rise to the pilot flame.
- the base 5 is removably mounted or secured to the cooking support surface 1 by via a mounting fixture fast such as 33, for example of the bayonet type, bringing together, through plan 1, an extension lateral or neck 34 of the elbow 3.
- a mounting fixture fast such as 33, for example of the bayonet type
- Two seals for example O-rings, 35 and 36 seal on either side of the support plane 1.
- the outer peripheral shoulder conical 26 of the base 5 onto which is fitted and rests on the inner peripheral edge of the part central 18 of the grid has a profile complementary to that of the grid.
- the complementary profiles of these edges can have different shapes, for example example that of a straight shoulder with or without stop allowing a cylindrical fitting simple or any other form of profile ensuring fitting with or without setting.
- circular rim grid top can be replaced with a piece intermediate.
