Description

[0001] The invention relates to a gas burner arrangement of a food cooking appliance. In particular, the invention relates to an arrangement of two spaced-apart gas burners of a food cooking appliance and a flame bridge arranged between the gas burners, which serves to mutually ignite the gas burners.

[0002] Examples of food cooking appliances with gas burners include gas grills. The arrangement relating to the invention is typically housed in a combustion chamber of a food cooking appliance, above which food is cooked by the heat emitted by the gas burners, for example, grilled on a grill.

[0003] A food cooking appliance may be designed to have several gas burners arranged side by side at a distance from each other, usually in the same plane, to increase the cooking surface. The gas burners in such an arrangement are often rod burners.

[0004] Gas burners are supplied with fuel gas and usually have a plurality of gas outlets from which fuel gas escapes. This fuel gas is burned when the gas burner is in operation. The gas outlets are arranged in a row so that ignited fuel gas flowing out of one gas outlet also ignites the fuel gas flowing out of a neighboring gas outlet. This means that the distance between the gas outlets must not be too great. To ignite the fuel gas when a gas burner is started up, ignition mechanisms are typically used, such as piezo igniters, which are arranged near a gas outlet. A gas burner from whose gas outlets ignited fuel gas flows is referred to below as an operating gas burner.

[0005] It may happen that a gas burner in the system goes out during operation, thus extinguishing the flames. This can be caused, for example, by a gust of wind or by extinguishing the food being cooked. In this case, fuel gas continues to escape from the gas burner. This condition is referred to below as an extinguished burner. The burner is then no longer in operation.

[0006] A similar problem can also occur with the initial ignition of the gas burner, for example because the ignition of a gas burner is not working properly or is not intended.

[0007] The escape of fuel gas from an extinguished gas burner represents a safety risk, so that it must be ensured that an extinguished gas burner must be automatically re-ignited within a predetermined, usually short period of time of a few seconds to a few tens of seconds, as long as a neighboring gas burner is still in operation, in order to prevent a sudden deflagration of the fuel gas escaping from the extinguished gas burner.

[0008] Flame bridges are used to enable the re-ignition of an extinguished gas burner. Flame bridges extend between two adjacent gas burners and, if necessary, transfer a flame from the still-operating gas burner to the extinguished gas burner. To transfer a flame, the flame bridge itself can also have gas outlets through which the fuel gas can escape and ignite. In another design, the fuel gas held in or on a flame bridge is ignited entirely, whereupon a wall of flame travels along the flame bridge, enabling the flame to be transferred from one gas burner to the other.

[0009] In the prior art, for example, US 9,933,157 B2 discloses a flame bridge between two rod burners, which is fed by fuel gas flowing from the gas outlet openings of the two gas burners. For this purpose, the flame bridge is designed so that its ends facing the gas burners fit closely to the respective gas burner. For attachment to the gas burner, it is screwed to the top of the gas burner. The flame bridge disclosed in the US document itself has gas outlet openings from which the fuel gas can escape, ignited by the flames of the adjacent gas burners. The flame bridge thus essentially represents a standalone gas burner. To protect the flames, the flame bridge has a protruding roof above the gas outlet openings.

[0010] EP 4 193 893 A1 discloses a flame bridge that is attached to the underside of a rod burner with a screw connection. It is also fed through the gas outlet openings of the rod burner used here. It also completely encloses the gas outlet openings of the gas burner. The same applies to EP 4 193 894.

[0011] DE 10 2006 009 580 A1 discloses a flame bridge that is attached to a rod burner by a clip connection. For this purpose, the flame bridge has a bracket at each of its distal ends, which encloses more than one semicircle of a tubular rod burner and, in the mounted position, encompasses the outer wall of the rod burner. This design also completely encloses the gas outlet openings of the gas burner to which the flame bridge is mounted.

[0012] Several problems can be identified in the above-mentioned designs: Due to their location, flame bridges are exposed to high heat, dripping fats, salts, etc. from the food being cooked, and thus to an extremely corrosive environment. Therefore, over time, the screw connection clamping the flame bridge to the gas burner may no longer generate sufficient clamping force due to corrosive material loss. In the worst case, the screw head is sheared off. At the same time, retightening the screw connection is often no longer possible due to contact corrosion between the screw and the gas burner. Repairs then require the entire gas burner, including the flame bridge, to be replaced.

[0013] Furthermore, the assembly and manufacture of the previously known flame bridges is relatively complex.

[0014] In addition, with the previously known arrangements of gas burners and flame bridges, deflagration noises can be heard during operation. This is due to the fact that small amounts of unburned fuel gas accumulate in the flame bridges and, at a certain level, suddenly explode. The deflagration noise is also clearly audible during re-ignition, which can be irritating to the user.

[0015] The invention aims to solve at least one of the problem areas.

[0016] This object is achieved by a generic arrangement mentioned at the outset with the features of one of claims 1, 5 or 11. Further advantageous embodiments emerge from the dependent claims and the description.

[0017] When reference is made to “top” or “bottom” in these explanations, this refers to the installation situation of the arrangement in a food cooking appliance.

[0018] According to a first proposed solution according to the invention, the gas burners each have a plurality of gas outlet openings arranged next to one another, approximately at a distance of 1 to 10 mm. These are usually rod burners. According to the invention, the flame bridge is held by a fastening means at at least one gas outlet opening of a gas burner. For this purpose, the fastening means engages in the at least one gas outlet opening. In a clever way, an opening already present in the gas burner is thus used for the holder orthe connection of a flame bridge, so that, should a replacement of the flame bridge become necessary, this can be carried out in a simple manner: If, in the event of a replacement, the fastening means of the flame bridge must remain in the gas outlet opening, for example because it cannot be removed due to contact corrosion, another gas outlet opening, for example a neighboring one of the gas burner, can simply be used for the holder or connection of the flame bridge.

[0019] Preferably, the fastening means engages two gas outlet openings of the gas burner, between which at least one gas outlet opening is provided, into which no fastening means engages. The flame bridge is fed with fuel gas through this gas outlet opening. This means that between the two gas outlet openings to which the flame bridge is attached to the gas burner, at least one gas outlet opening is provided that is not used for fastening. Instead, the full cross-section of the at least one free gas outlet opening is used to feed the flame bridge with fuel gas. The flame bridge captures the fuel gas escaping from this gas outlet opening.

[0020] By at least partially closing those gas outlet openings to which the flame bridge is attached to the gas burner, an anomaly is created that influences the fuel gas flow flowing out of the intermediate gas outlet opening, which can generate a certain overpressure and / or turbulence in this area, which promotes the escape of fuel gas from the free gas outlet opening.

[0021] This effect can be enhanced by extending the fastener into the interior of the gas burner. This extension locally slows the flow of the fuel gas and creates additional turbulence. Furthermore, such a section of the fastener can be designed to direct the gas flow.

[0022] Preferably, the at least one gas outlet opening, to which the flame bridge is attached to the gas burner, is not completely closed by the fastening means. Thus, despite its use as a fastening point, fuel gas can escape from the gas outlet opening, which can be ignited by the flames from the adjacent gas outlet openings. This ensures flame transfer between the gas outlet openings that are adjacent to the gas outlet opening to which the flame bridge is attached.

[0023] In principle, the fastening means for attaching the flame bridge to the gas burner can be a screw, a cotter pin, or another additional part. However, it is preferably provided that the fastening means is designed as a retaining extension of the flame bridge, which, when the flame bridge is mounted, protrudes into the gas outlet opening. The retaining extension is molded onto the remaining part of the flame bridge and is an integral part thereof. Preferably, the retaining extension is located at the distal end of the flame bridge and protrudes from it.

[0024] Typically, the retaining extension is straight, designed as a pin, for example. This simplifies assembly. The retaining extension preferably only partially closes the gas outlet opening. For this purpose, the retaining extension can be designed as a sheet metal part. Part of the gas outlet opening remains open.

[0025] By providing a retaining extension, a plug-in solution is proposed that offers cost advantages in both production and assembly.

[0026] For example, the retaining extension can also be designed in a hook shape. The retaining extension then engages, at least in sections, behind the opening in the gas burner provided by the gas outlet. This simplifies assembly, as the flame bridge can be sequentially mounted loosely on one gas burner first and then mounted on the other gas burner to finalize the assembly.

[0027] If the flame bridge is mounted on both gas burners using a plug-in solution, it is preferable to have hook-shaped retaining projections on one side of the flame bridge and straight on the other. This also simplifies installation.

[0028] According to a second proposed solution according to the invention, it is provided that the flame bridge has a receptacle for holding the flame bridge on at least one gas burner, and wherein the flame bridge has a holding extension that projects into the receptacle for fastening the flame bridge to the at least one gas burner. In this way, tool-free assembly is possible; additional fastening means are not required. The holding extension is an integral component of the flame bridge and is thus molded onto it. Due to the one-piece provision of the holding extension on the flame bridge, it can be manufactured directly during the molding of the flame bridge.

[0029] The mount on the gas burner can be recessed, creating a cup-shaped recess and leaving no perforation in the gas burner area. This ensures absolute gas tightness of the mount.

[0030] In another embodiment, it can be provided that the receptacle is designed as an opening leading into the interior of the gas burner and that the flame bridge essentially closes the opening. "Essentially" means that gas-tightness is not absolutely required. Rather, advantage is taken of the fact that the opening providing the receptacle only needs to be significantly more closed than the at least one other gas outlet opening, usually the multitude of other gas outlet openings of the gas burner. The gap between the wall of the opening in the gas burner and the flame bridge, or holding extension, only needs to be so small that the pressure required for a significant amount of fuel gas to escape from the gas burner through the receptacle is significantly greater than the pressure under which the fuel gas must be in order to escape from the provided gas outlet openings.The significantly larger cross-section of the gas outlet openings, which are usually arranged in the immediate vicinity of the opening forming the receptacle, is thus used to prevent excessive gas escape from the opening when the flame bridge is installed.

[0031] Preferably, the opening is slit-shaped. By providing a greater longitudinal extension than width extension, precise orientation of the flame bridge relative to the gas burner is possible only with a continuous opening. Typically, the longitudinal extension of the slot points in the longitudinal direction of the gas burner.

[0032] In addition, it can be provided that several openings are provided to which the flame bridge is attached and which openings are closed by the flame bridge.

[0033] The holding extension can be designed in a special way, as already mentioned above: for example, protruding into the interior of the gas burner, straight or hook-shaped, in particular barb-shaped.

[0034] If the retaining extension is hook-shaped, particularly barbed, it can be provided that, in the mounted position, the retaining extension, for example with its hook portion, contacts the inner wall of the gas burner in the area of ​​the opening in an umbrella-like manner, thus sealing the opening from the inside. Umbrella-like configurations include both flat designs of a cover plate and curved or segmented designs.

[0035] According to a third proposed solution according to the invention, the flame bridge is designed to be fed by fuel gas flowing out of at least one gas outlet opening and to guide fuel gas from a gas outlet opening of an extinguished gas burner to a gas outlet opening of the other, burning gas burner. If one gas burner is extinguished, fuel gas continues to flow out of the gas outlet opening of the gas burner - at least without the fuel gas being shut off. The escaping fuel gas is captured in the flame bridge and, since it is heavier than the ambient air, is held in the flame bridge, which is designed as a groove, at least in the lower area. The fuel gas flows via the flame bridge from the extinguished gas burner to the gas burner in operation.When the fuel gas flow from the extinguished gas burner reaches the flame of the burning gas burner, the fuel gas flow ignites, so that a wall of flame runs from the burning gas burner to the extinguished gas burner and reignites the extinguished gas burner.

[0036] In the described solution, which can be implemented both in combination with and independently of the proposed solutions described above, it is provided that the flame bridge has at least two sections along its longitudinal extent, wherein in the region of the gas outlet opening feeding the flame bridge, an upwardly open deflagration basin following the longitudinal extent of the flame bridge is provided as a first section, to which an upwardly closed channel adjoins as a second section of the flame bridge.

[0037] While in the prior art the flame bridge encloses a gas outlet opening feeding the flame bridge as extensively as possible, the invention assumes that only a basin open at the top is provided in the area of ​​the gas outlet openings to collect the escaping fuel gas at the bottom. Since fuel gas is heavier than air, it is sufficient if the flame bowl in this area is trough-shaped, i.e. a pan with a bottom and side walls. Typically, the deflagration basin is at least 8 mm long in the longitudinal direction of the flame bridge. Preferably, it is at least 10 mm, more preferably at least 12 mm long. By providing a basin, noise development during operation is reduced: If the fuel gas collected in the basin is ignited, the expanding air can expand relatively freely, so that the deflagration noise is not amplified like a muzzle sound, as would be the case with a closed duct.

[0038] It was also recognized that even during normal operation of the gas burner, fuel gas accumulates in the flame bridge that has not been completely combusted. If the amount of collected fuel gas swells to a critical volume, it ignites upon contact with the flame. By providing an open-topped basin as part of the flame bridge, a large portion of the fuel gas is burned in an unrestricted space, allowing the air expanding during combustion to expand without turbulence, resulting in overall lower noise levels.

[0039] Adjacent to the basin, the first section of the flame bridge, is a channel-shaped, closed-top second section. The fuel gas contained in the flame bridge is guided in this second section, protecting it from convection in the combustion chamber.

[0040] Typically, this second, closed section is followed by another first section, designed analogously to the first. The flame bridge then has a deflagration basin at each end facing the gas burners, with a closed channel inserted between them.

[0041] Preferably, a transition section following a flame bridge is provided between the first and second sections, in which the cross-section of the flame bridge is continuously closed along the longitudinal extent of the flame bridge, from the upwardly open deflagration basin to the upwardly closed channel. In this way, flow separation of expanding air is reduced when, upon re-ignition of one gas burner, the flame wall runs from the operating gas burner to the extinguished gas burner. A linear transition is provided in the transition section, extending approximately 1.5 times the width of the flame bridge.

[0042] The embodiments described below apply to all the proposed solutions according to the invention described above: The flame bridge is designed in its lower section as a channel, with a base and attached, typically molded walls, to hold and guide the fuel gas, which has a higher specific gravity than the ambient air. Thus, the flame bridge can be open at the top or at least partially closed. In the latter case, the flame bridge is designed as a channel.

[0043] The flame bridge is typically designed to capture unignited fuel gas escaping from at least one gas outlet and direct it to the second gas burner for ignition. Therefore, the flame bridge element that captures the fuel gas is located below such a gas outlet.

[0044] The flame bridge is preferably designed as a stamped and bent part. This allows for simple and cost-effective production. Any retaining extension can also be provided integrally in this way.

[0045] Preferably, it is further provided that the flame bridge has, at least in sections, a drop-shaped cross-section, with a bulge directed downwards and a tapered cross-section in the upwardly directed region. This provides an aerodynamic flame bridge that can also be easily manufactured by bending material.

[0046] For example, the flame bridge can also be provided with two adjacent, vertically oriented flanges, at least in some sections of its upward-facing area. These flanges can not only serve as a joint between two adjacent side walls of the flame bridge, but also stabilize the flame bridge against bending, especially during assembly.

[0047] The gas burners used are typically tubular gas burners, so-called rod burners. These have closely spaced gas outlets arranged in a row, ensuring flame transfer between two adjacent gas outlets.

[0048] Furthermore, it is preferably provided that the gas outlet openings of the gas burners are aligned horizontally. In this context, "horizontally aligned" means a substantially horizontal discharge of the flames, i.e., that the flames leaving the gas burner during operation are discharged laterally. Typically, such a gas burner has gas outlet openings on opposite sides, so that a certain width above the gas burner is heated with one gas burner.

[0049] The invention is explained in more detail with reference to the accompanying figures. They show: Fig. 1: A three-dimensional view of an arrangement of several gas burners in a side-by-side arrangement and spaced apart from each other with flame bridges inserted between them, Fig. 2: a single gas burner with a flame bridge attached to it, Fig. 3: a detailed view of a section of Fig. 2 and Fig. 4: a single representation of a flame bridge.

[0050] Fig. Figure 1 shows an arrangement 1 of several spaced-apart gas burners 2, 2.1, 2.2, 2.3, here configured as tubular rod gas burners, of a food cooking appliance (not shown). The gas burners 2, 2.1, 2.2, 2.3 are all identically constructed; to simplify the description, reference will be made below to only one gas burner 2.

[0051] The gas burner 2 is held at its distal ends on the food cooking appliance (not shown), namely on a suspension 3 and in the region of its fuel gas inlet 4. Fuel gas is introduced into the interior of the gas burner 2 through the fuel gas inlet 4.

[0052] The fuel gas introduced into the gas burner 2 exits through a plurality of gas outlet openings 5, 5.1, which are arranged side by side in the gas burner 2 as openings leading into the interior of the gas burner 2. They are spaced such that when the fuel gas exiting a gas outlet opening 5, 5.1 is ignited, the fuel gas flowing out of an adjacent gas outlet opening 5, 5.1 is also ignited, so that the fuel gas flowing out of the gas burner 2 is completely ignited through a chain reaction. The flames are emitted horizontally from the gas burner 2.

[0053] For the flame-technical connection of one side of the gas outlet opening 5 with the gas outlet openings 5.1 on the opposite side of the gas burner 2, auxiliary gas outlet openings 6 are provided, through which a flame transfer from one side of the gas burner 2 to the other side is made possible.

[0054] A flame bridge 7, 7.1, and 7.2 is provided between each of the gas burners 2, 2.1, 2.2, and 2.3. Flame bridges 7, 7.1, and 7.2 are identical in design, which is why the following description refers only to flame bridge 7.

[0055] The flame bridge 7 is designed to be fed by fuel gas flowing out of at least one gas outlet opening 5.

[0056] The operation of the flame bridge 7 is explained below: Two gas burners 2, 2.1 arranged side by side are in operation, i.e., they are supplied with fuel gas and both are ignited, so that the fuel gas flowing out of the gas outlets 5, 5.1 burns. Any external circumstance, such as the extinguishing of food cooked above the arrangement 1, completely extinguishes the flames of the gas burner 2. In this case, fuel gas continues to escape from the gas burner 2, but it is not combusted due to the lack of flame. The fuel gas, being heavier than air, collects at the bottom of the combustion chamber, creating the risk of explosion.

[0057] To counteract this, the flame bridge 7 is installed. The fuel gas of the extinguished gas burner 2 escaping from the gas outlet opening 5 in the area of ​​the flame bridge 7 is collected in the flame bridge 7 and flows to the adjacent, still burning gas burner 2.1. As soon as the fuel gas flow reaches the flame of the burning gas burner 2.1 via the flame bridge 7, the fuel gas ignites on the flame bridge and a wall of flame runs along the fuel gas flow over the flame bridge 7 back to the extinguished gas burner 2. There, the wall of flame ignites the fuel gas flowing out of the gas outlet openings 5 ​​there, so that the gas burner 2 is re-ignited as a whole.

[0058] Details of arrangement 1 and flame bridge 7, 7.1, 7.2 are given with reference to the Fig. 2 to 4 are explained in more detail below.

[0059] For fastening the flame bridge 7 to the gas burners 2, 2.1 (in the Fig. 2 and Fig. 3, only one gas burner 2 is shown for clarity, but the flame bridge 7 is attached to the gas burner 2.1 in the same way. The flame bridge 7 has fastening means 9 at its ends facing the gas burners 2, 2.1, here configured as two holding extensions 8a, 8b each. With these two holding extensions 8a, 8b, the flame bridge 7 projects into two gas outlet openings 5a, 5b in the interior of the gas burner 2. The flame bridge 7 is inserted into the gas outlet openings 5a, 5b.

[0060] Between the two gas outlet openings 5a, 5b, into which the retaining extensions 8a, 8b are inserted, a further gas outlet opening 5c ​​is provided. The flame bridge 7 is supplied with fuel gas through this fully open gas outlet opening 5c.

[0061] In the embodiment described here, the retaining pins 8a, 8b only partially close the gas outlet openings 5a, 5b; the gas outlet openings 5a, 5b are not completely closed, so that fuel gas can also escape from them during operation, which can be ignited by adjacent flames, usually the flames of the respective adjacent gas outlet openings 5c, 5d, 5e, so that a flame jump is also possible beyond the fastening of the flame bridge 7 in the gas outlet openings 5a, 5b.

[0062] The flame bridge 7 itself comprises two first sections 10, 10.1 and a second section 11 arranged between them. The two first sections 10, 10.1 merge into the intermediate second section 11 in a respective transition section 12, 12.1. All sections 10, 10.1, 11, 12, 12.1 have a certain extension in the longitudinal direction of the flame bridge 7.

[0063] The first section 10, 10.1 is designed as an upwardly open deflagration basin 13, 13.1 following the longitudinal extension of the flame bridge 7. The deflagration basin 13, 13.1 collects the fuel gas escaping from the outlet openings 5, in particular the outlet opening 5c. Thus, even when a gas burner 2 is in operation and burning, unburned fuel gas is collected in the deflagration basin 13, 13.1. If the fill level in the deflagration basin 13, 13.1 reaches a critical level, the fuel gas collected there is ignited, resulting in a deflagration. Because the deflagration basin 13, 13.1 is upwardly open, hardly any additional turbulence is generated during this deflagration, thus minimizing noise generation. Therefore, the deflagration basin 13, 13.1 extends over a significant section along the longitudinal extent of the flame bridge 7, here approximately 12 mm.

[0064] In the second section 11, the flame bridge 7, which is designed as a channel 14, the fuel gas held there is protected against external influences, in particular against convection in the combustion chamber. In the event that one of the two gas burners 2, 2.1 is extinguished, it is necessary for the fuel gas escaping from the gas outlet opening 5c ​​of the extinguished gas burner 2 to be guided to the burning gas burner 2.1. To prevent the fuel gas from escaping from the flame bridge 7 along its path, for example, due to convection, the flame bridge 7 is closed at the top in the middle, second section 11.

[0065] The transition section 12, 12.1 arranged between the two first sections 10, 10.1 and the second section 11 serves to continuously adapt the cross-section of the flame bridge 7 from the open deflagration basin 13, 13.1 to the closed channel 14 in the second section 11 over the longitudinal extent of the flame bridge 7.

[0066] The flame bridge 7 is designed as a stamped and bent part. The seam where the two walls of the channel 14 are joined in the second section 11 is designed as upward-facing flanges 15.

[0067] In cross-section, the flame bridge 7 in the second section 11 is drop-shaped: a bulge is provided pointing downwards, while pointing upwards the flame bridge 7 tapers to a point.

[0068] The invention has been described using exemplary embodiments. Without departing from the scope of protection described by the applicable claims, numerous further embodiments for implementing the inventive concept will become apparent to those skilled in the art without the need for further explanation within the scope of these statements.
