Definitions
- the present invention relates to a gas burner for a cooking appliance such as a stove or a cooking.
- the present invention also relates to a method for mounting and using a gas burner for culinary appliance.
- Each of these two types includes a gas injector opening into a mixing chamber in which the gas is first mixed with air, called “air primary ". This mixture then passes through a venturi which leads to flame ports. At the exit of these the mixture undergoes combustion thanks to the addition of a second amount of air, called “secondary air”.
- the two types of burners mentioned above are distinguished by the method of conveying primary air into the mixing chamber.
- a first type known from the journal ENERGIETECHNIK, 8 th year, n ° 5, May 1958, page 230 the primary air is taken above the hob, through an annular gap between the hob and the free edge of a peripheral skirt of the burner superstructure.
- the tank is generally closed. Closing the tank has advantages, particularly with regard to certain flame stability standards in the event of a "gust of wind" in the region below the hob.
- These burners provide unsatisfactory primary ventilation, because the path of primary air from the annular gap and bypassing the base of the venturi path, presents high pressure drops.
- these burners are subject to the risk of flame extinction when a flooding of the hob closes the annular gap and / or reaches the mixing chamber from the top of the hob, by the same path that primary air.
- the second type of burners known from FR-A-1 197 178 (SAUTER), have an open mixing chamber laterally, allowing primary air to be taken from the region on the appliance located below the hob. These burners have poor wind resistance likely to occur below the cooktop, for example example in case of abrupt closing or opening of a door access to the volume located under the hob.
- FR-A- 2 507 743 describes a burner combining a radial primary air supply above the hob with the injector mounted in a vertical sleeve forming an opening around the injector ring for the main intake of primary air from under the Cooktop. This burner remains sensitive to gusts of wind under the hob.
- the object of the invention is thus to propose a gas burner with great flexibility of use from the point of view of its assembly, and / or the quality of its combustion even for different kinds of gas, and / or its safety.
- the invention provides a gas burner according to the preamble of claim 1, which burner, being arranged in accordance with the invention, is characterized by the provisions set out in the part Characterizing of claim 1.
- the burner according to the invention ensures a very high aeration primary, therefore excellent combustion quality especially with regard to the standards on the maximum rate of carbon monoxide.
- the burner is surprisingly effective against the risk of flame extinction.
- the presence of the two routes instead of adding the risks presented by each of them, has at on the contrary, by virtue of eliminating them. So if the ride main is closed, the additional path ensures still some primary ventilation.
- the path through the tank is only a complementary path, ensuring an air flow for example about five times lower than the main path, its passage section is weak and does not allow gales to reach the mixing chamber.
- the secondary route constitutes a discharge port for 'substances likely to accidentally enter the room mixing by the primary path. This security is particularly insured when, in accordance with a specific feature optional of the invention, the complementary route opens at a low point in the mixing chamber.
- the additional route is arranged to provide, if the main route is blocked, a primary ventilation just sufficient to meet standards for maximum levels of carbon monoxide in the combustion gases produced by the flame of the burner. So the section of the complementary path is as small as possible so that all of the above benefits are obtained optimally. So the path additional must be fitted to provide primary ventilation corresponding to approximately 10% of the stoichiometric value required for petroleum gas which is the most difficult fuel. These 10% add to the 50% that the main air path primary is able to provide. The burner therefore totals which is the most difficult fuel. This 10% is added to 50% that the primary path of primary air is capable of providing. The burner therefore totals primary ventilation corresponding to 60% of stoichiometric aeration. This is remarkable and then allows, through secondary aeration, combustion producing rates of very low carbon monoxide, well below standards currently in force.
- the primary air path extending between the inlet means primary air and the tank can be produced with a very low pressure drop decreased compared to the currently known achievements.
- the axial part of the venturi, leading to the neck and diverging radially oriented can be considerably shortened without degrading the operation of the venturi.
- These baffles were intended according to the state of the technique to improve difficult combustion by restricting air primer to lick hot walls before mixing with gas.
- the burner to gas comprises a tank 1 of generally frustoconical shape.
- the open top edge of tank has flange device 2 intended to be fixed against the face bottom of a hob 3, using screws 4.
- the hob 3 has an axial opening 5 through relation to which the open end of the tank is centered 1.
- the bottom of the tank 1 carries a gas injector fuel 6 mounted to release combustible gas 7 in a jet extending upwards along the vertical axis 8 of the tank 1 and the opening 5.
- the interior of the tank 1 constitutes a mixing chamber 9 in which the gas 7 is intended to mix with combustion air called air "primary", taken from the atmosphere.
- a main path of primary air it is arranged between the upper side of the hob 3 and the side bottom of a wall 12 which belongs to a body upper 17 of the burner.
- the wall 12 is finished, radially outwards, by a skirt 13 oriented obliquely downwards, so towards the upper face of the hob 3.
- the free edge 14 of the skirt 13 and the upper surface of the hob 3 define between them an annular inlet interval for primary air main around the entire burner.
- the body upper 17 belongs to a superstructure 16 of the burner. This further comprises a cover 18 covering the upper body 17.
- the upper body 17 includes a hole central defined by a collar 19 projecting towards the mixture 9 along axis 8 and intended to conduct the mixture of gas and primary air in a defined radial venturi an upper face of the upper body 17 and a face substantially flat bottom of the cover 18.
- the venturi radial includes, from the upper end to collar 19, opposite the injector 6, a collar 21 of the venturi and a divergent 22 extending radially outwardly start at collar 21.
- the divergent forms for the mixture a passage section which grows very quickly, thanks to cumulative increase in diameter, and distance between the upper face 23 of the upper body 17 and the underside of the cover 18.
- the divergent 22 opens out in an annular pressure relief chamber 24 which is separated from the main path 11 by the wall 12. Radially outside, the recovery chamber of pressure 24 is limited by a side wall 26 whose upper edge is crenellated and supports the cover 18.
- the slots form flame openings 27, limited above by the cover 18.
- the plane 28 containing the free edge 14 of the skirt 13 extends between the injector 6 and the free bora 29 of the collar 19. It the same goes for the plane of the upper face of the table cooking 3 in the substantially flat region which defines the main path 11.
- the collar 19 does not not protruding downward from a radial plane (substantially the plane 28) containing the main path 11. The latter can therefore be substantially straight up to what he must change direction to enter the collar 19. This is obtained without increasing the total height of the burner, by simply reducing the length of the collar 19, compared to conventional embodiments.
- the mixing chamber 9 is in additionally supplied by an additional primary air path 31 comprising a complementary opening 32 formed at through the wall of the tank.
- the complementary opening 32 extends through a boss 33 on the outer face of the tank 1, and opens into the mixing chamber 9 in one low point of the tank, near the injector 6. Parallel to its axis, the opening 32 has a certain length, giving the air flow passing through it some directivity, and making this air flow relatively insensitive to unwanted flows which can exist near the outer walls of the tank 1. Thanks to the advantageous arrangement which has just been described for the complementary opening 32, the complementary path 31 is almost straight and parallel to the gas flow 7 entering the collar 19. Thus, one or more small section openings 32 provide flow substantial with reduced pressure drop.
- the gas jet 7 drives with him to the pressure relief chamber 24 and to flame openings 27 the primary air arriving through the main path 11 and the complementary path 31.
- the journey main 11 provides ventilation corresponding to approximately 50% of the stoichiometric value and that the journey additional 31 provides ventilation corresponding to 10% stoichiometric value for petroleum gas liquefied.
- a secondary ventilation takes place, with air taken from the atmosphere surrounding the outside of the wall lateral 26.
- Figure 2 illustrates that one can if one wishes to have more than one complementary opening 32, which can then be of smaller section.
- the daily maintenance of the burner according to the invention is particularly simple.
- the superstructure is positioned on the tank 1 by centering feet 34 leaving pass between them the main path 11.
- the base of the feet 34 rests on the edge of the tank 1.
- the hob 3 forms, around the opening 5, a dome 37 of more diameter weak than the free edge 14 of the skirt 13, so as to make appear, radially outside the dome, the interval entry ring of the main air path 11 primary.
- FIGs 3 to 6 illustrate one aspect of the invention relating to the mounting of a spark plug 41.
- the end active 42 of the candle 41 is positioned in a socket generally semicircular 43 defined by the face outer side wall 26 of the superstructure.
- Mon flame ports 27 is located at the bottom (radially interior) of this cell 43, as shown in Figures 3, 4 and 5.
- the top of the cell is closed by the cover 18.
- This cell which opens radially towards outside, protects the candle and in particular its end active 42 with respect to food depots, but has disadvantage of making it more difficult to supply air secondary for ignition.
- replacing the candle is complex and Depending on the state of the art, often requires a major disassembly of the burner, making the operation difficult for the user of the culinary appliance.
- the candle is removable from above the hob.
- the body of the candle extends through one ear 44 of the peripheral flange 2 of the tank 1.
- the spark plug 41 has a lateral fixing plate 46 which is placed on the upper face of the ear 44 and can be screwed to the ear 44 by means of a screw 47.
- the plate 46 extends towards the axis 8 of the burner.
- the body 45 of the candle 41 carries a connection lug 49 connected to a wire high-voltage power supply 48.
- the assembly comprising the candle 41 and the end adjacent to the wire 48 can be waxed above the table firing 3, this after removal of the superstructure 16, as shown in Figure 4.
- the periphery of the opening 5 of the hob 3 forms a notch 52 into which the face fits upper ear 44.
- body 45 of the spark plug extends upward through path 11 of air primary and through an opening 53 made in the wall 12.
- the active end 42 of the spark plug thus protrudes in cell 43 forming a flame zone for the flame ignition.
- the opening 53 is large enough to leave a substantial play around the body of the candle 45 forming a path 54 for secondary air which is taken in path 11 and ends up in cell 43 at outlet of the flame orifice 27 associated with this cell. The ignition of the burner is thus favored by an additional secondary air.
- Figures 7 to 9 relate to another aspect of the invention relating to the mounting of a flame detector intended to control the cut off of the gas supply when the overheating resulting from the presence of the flame disappears.
- FR-A-2 660 309 describes how such a detector can be achieved by means of a thermocouple.
- the welding 61 sensitive to temperature, forming the free end thermocouple 64 is placed substantially at mid-distance between the axes of two flame orifices 27 arranged at the bottom of a cell 62 formed by the face exterior of the side wall 26 of the superstructure.
- the FR-A-2 660 309 also describes other provisions possible, also consistent with this aspect of the invention, in particular with a single flame orifice influencing the solder 61 of the thermocouple.
- the thermocouple includes roughly in the middle of its height of a connection lug 63.
- the thermocouple 64 is fixed to the particularly simple burner by pinching the proximal part 66 of lug 63 between the underside of the hob 3 and an ear 67 of the flange 2 of the tank 1.
- the ear 67 has on its upper face a recess 68 to accommodate the thickness of the part proximal 66, and a hole 69 for the passage of the part thermocouple down.
- the hob 3 has a hole 71 to allow the upper part of the thermccouple to extend upward through the primary air path 11. This cools the weld thermocouple (not visible in the figures).
- thermocouple then extends through an opening 72 formed in the wall 12 separating the path 11 on the one hand and the volume of the cell 62 on the other hand.
- the opening 72 is sized to present considerable play around thermocouple 64 so that an air flow secondary, taken from the primary air path 11, passes by this play in the cell 62 and promotes the maintenance of flames 73 licking the hot solder 61 of the thermocouple.
- FIG. 10 relates to an improvement relating to the connection of injector 6 (not shown in this figure) with a gas pipe 81.
- the tank 1 is produced in such a way as to include, when molded, a fitting 83 for fixing the gas pipe 81 to tank 1 in a position or this pipe communicates with the injector 6 via a conduit 82 also coming from molding (see also figure 1).
- Fitting 83 forms a widening at the open end of the conduit 82. This enlargement is defined by a lower surface cylindrical threaded 84 terminated inside by a convex conical shoulder 86.
- the thread 84 is intended for receive an externally threaded clamping sleeve 87 and having at its end facing the shoulder convex conical 86 a corresponding concave conical face 88.
- Pipe 81 has a flare at its end or conical flange 89 intended to be clamped between the faces 86 and 88 above.
- the collar 89 comprises, at from the tubular part of the pipe 81, a part 91 extending conically outwards, followed by a terminal flange 92 folded against the inner face of part 91.
- the terminal flange 89 has a axial elasticity due to the more or less complete folding of the flange 92 against part 91.
- the conical flange 89 forms a spring between the faces 86 and 88. This prevents any loosening of the socket 87, whatever the temperature variations, and differences in expansion which may result between the material of the tank 1, of the socket 87 and the pipe 81.
- FIG 11 shows the processes according to the invention.
- a burner can be strictly identical to the one or those described so far, and by therefore capable of being mounted as has been said up present relative to hob 3, can also be mounted on a cooktop 103 which is shaped so that the free edge 14 of the skirt 13 comes into substantially sealed contact with the face top of the cooktop 103.
- the dome 37 has a flat top whose diameter is enlarged, to be now greater than that of the free edge 14 of skirt 13.
- a fully flat work table would be also conceivable.
- the burner described is capable, by simple difference in the shape of the hob, operate as a burner taking at least part substantial of its primary air above the table cooking or on the contrary in a burner not taking air primary than under the hob.
