Description

[0001] The invention relates to an additional burner for a grill and a suitable grill, in particular a gas grill for grilling, cooking or baking food on a grill grate or the like, especially for outdoor use, on which the additional burner can be arranged.

[0002] Grills and gas grills for cooking food have at least one grill body with a grill grate or similar surface for placing the food on, as well as a heat source underneath, in particular glowing charcoal, pellets, heating elements, or gas burners. Depending on the grill's features, a lid or hood is also provided to close the grill body. On simple grills, the lid is separate from the grill body and can be placed on top. However, on many grills, the lid is permanently attached to the grill body, often as a hinged lid.

[0003] From EP 0653917 B1, an outdoor grill is known in which a wall is inserted between a heat source, in particular a gas burner ring in the lower part of a grill container, and a grate for supporting the food being grilled. This wall prevents droplets from the food being grilled, especially fat or water, from dripping onto the heat source and collects such droplets above the heat source. The droplets are then directed into a container located below the heat source. The areas of the wall that cause droplets to evaporate due to their temperature are inclined at an angle of 30° to 70° to the horizontal. The wall is formed in the shape of spherical shell segments. It contains a conductive material that guides the droplets into a central recess in the heat source and from there into a container located below the heat source.

[0004] In a gas grill according to DE 202012100587 U, a grease collection device is arranged below a burner unit, comprising several grease collection trays positioned side by side. A similar solution is disclosed in US 4909137 A. Drainage angles (DE 08804071 U) or channels (DE 2020099014563 U) can also be used instead of trays.

[0005] Another grill of this type features a heat conduction system that allows for both direct and indirect cooking. In direct grilling, the heat from the heat source is directed straight onto the food with the lid open. In indirect grilling, the heat from the heat source is guided around the food by a heat conduction system and only reaches the food after being deflected under the closed lid. The grill body has an insert with closable openings for switching between direct and indirect heat. The openings can be opened and closed using a handle on the outside of the grill body, which is connected to the insert. German patent application DE 202014004089 U also proposes a burner cover made of V-shaped angled elements for homogeneous heat distribution, which covers the entire burner chamber.According to US 2002 / 195096 A1, a grill with various grilling options is disclosed, in which a burner cover is provided below the grill grate as a diffuser, which allows for indirect heating of the food being grilled.

[0006] From DE 60009979 T2, gas burners are known which interrupt the gas supply as soon as a pilot flame touches a flame protection thermocouple.

[0007] According to DE 102015109787 B4, a gas burner can be equipped with a tilting safety assembly, wherein a connecting pipe of the combustion device is fluidly connected to the tilting safety device at one end.

[0008] German patent application DE 202007019208 U1 discloses a burner assembly with a gas burner for a boiler, to which a semi-automatic ignition and monitoring device and a pilot burner are assigned. The pilot burner serves to provide a pilot flame during normal operation. The ignition and monitoring device contains an electronic control unit and is fluid-tight encapsulated for reigniting the pilot burner after an interruption of normal operation.

[0009] To improve grilling performance, it is also known to arrange burners or heating elements to the side of the grill grate and / or different grill grates or grill chambers can be provided for variable grilling.

[0010] The invention is based on the objective of creating an additional burner for a grill for grilling, cooking or baking food such as meat, fish or vegetables on a grill grate or the like, especially for outdoor use, which enables better performance when grilling and in particular also enables direct and indirect grilling simultaneously and in an energy-saving manner.

[0011] The problem is solved by the characterizing features of claim 1.

[0012] According to the invention, an auxiliary burner for a grill (gas, electric, pellet, or charcoal) comprises a heat source in the form of a ceramic burner that can be attached to the base of the grill. The auxiliary burner includes a top-opening trough in which the ceramic burner is located, a grate covering the ceramic burner, and a removable, grate-like heat diffuser positioned between the grate and the ceramic burner. This heat diffuser, in conjunction with the height-adjustable grate, enables grilling at different temperature levels, even heat distribution on the grate above, protection against harmful flare-ups, and thus a wide range of applications with minimal effort.

[0013] Another task is to design a grill with at least one additional burner according to the invention.

[0014] According to the invention, the grill is in particular a gas grill comprising a combustion chamber containing a burner arrangement, the combustion chamber being provided with a hinged hood which, when closed, covers the grill grate. The combustion chamber is arranged on a substructure, and the grill further comprises a flat base as a working surface.

[0015] At least one additional burner and / or at least one extendable table can be arranged as a work table at the base, wherein the extendable table and / or the additional burner has guide rails that are guided and lockable in guide tracks of the base, in particular in a horizontal direction.

[0016] The grill according to the invention is suitable for grilling, cooking or baking food such as meat, fish, dairy products, vegetables, fruit or baked goods on a grill rack or the like, especially for outdoor use.

[0017] Preferred embodiments are disclosed in the dependent claims.

[0018] Advantageously, the surface of the heat diffuser covering the ceramic burner is designed as a solid sheet, while the adjacent outer areas are equipped with slots on at least two parallel sides to allow grease or other liquids to drain into the drip tray. The heat diffuser is also positioned at an angle to facilitate grease runoff along the grooves.

[0019] The auxiliary burner features guide rails for positioning and securing it in the base of the grill. These rails are guided in grooves within the base and can be locked into place. The auxiliary burner can thus be easily "slid" horizontally into the base.

[0020] The auxiliary burner's grate is height-adjustable relative to the ceramic burner, allowing for both high and low heat for searing or grilling. The ceramic burner itself is also adjustable.

[0021] Advantageously, the auxiliary burner can also be designed as a gas burner in a different configuration. It comprises a housing with a removable tray inside, a centrally located and adjustable gas burner within the housing or tray, and a height-adjustable ring grate.

[0022] A grill with such an additional burner has a combustion chamber containing a burner assembly, and the combustion chamber may be equipped with a hinged hood that covers the grill grate when closed. The combustion chamber is mounted on a base. Advantageously, the grill also includes a flat base as a work surface, and at least one additional burner and / or at least one pull-out table can be arranged on the base. The pull-out table and / or the additional burner has guide rails and an integrated internal guide in the base.

[0023] Both types of auxiliary burners can also be combined in a single unit and arranged at the base. Likewise, an auxiliary burner can be positioned on each side of the combustion chamber.

[0024] A gas cylinder kit for a larger gas cylinder, for example with 11kg instead of 8kg, can also be arranged at the base.

[0025] The auxiliary burner can also include an open housing with a removable tray arranged inside, a centrally arranged and preferably controllable gas burner, and a height-adjustable ring grate.

[0026] The ring grate is preferably height-adjustable in relation to the aforementioned gas burner.

[0027] A major advantage of the height-adjustable rack is that changing the distance between the pot, pan, and burner opens up additional possibilities for food preparation. The lower position is suitable for high heat (searing, stir-frying, etc.), while the upper / highest position is suitable for low heat (e.g., keeping sauces warm). Combined with the adjustable gas burner, this results in a very wide range of applications. Previously, different sized burner heads were required for such a range. According to the invention, this is combined in a single burner.

[0028] The invention is described in more detail below using an exemplary embodiment and a drawing. The drawing shows the Fig. 1: a grill according to the invention; Fig. 2: an extendable table of the grill after Fig. 1; Fig. 3: an additional burner of the grill according to the invention Fig. 1; Fig. 4: the auxiliary burner after Fig. 3 in individual parts; Fig. 5: a second embodiment of an auxiliary burner; Fig. 6: the auxiliary burner after Fig. 5 in individual parts; Fig. 7: the grill Fig. 1 in a further embodiment; Fig. 8: a gas cylinder kit for the grill Fig. 1 and Fig. 9: a grill grate pizza stone kit for the grill according to Fig. 1.

[0029] A grill according to the invention, in the exemplary embodiment a gas grill 1 ( Fig. 1) has a hemispherical combustion chamber 4 in which a burner arrangement is arranged, the combustion chamber 4 being provided with a hinged, domed hood 2 which, when closed, covers a grill grate. The hood 2 is attached to the rear wall of the combustion chamber 4 by means of a hinge. The hood 2 is provided with a handle for opening and closing.

[0030] A flame guard is positioned between the burners of the burner assembly and the grill grate, which serves to reduce the danger or the effects of grease fires, etc.

[0031] The combustion chamber 4 is mounted on a wheeled, cuboid base 3, which is essentially made of metal, with one of the side walls 11 forming a door 27. Above this door 27 is a control unit 10 with at least one rotary handle ( Fig. 1) In the example, the rotary handle is surrounded by a ring of colored LEDs on the front panel. This ring illuminates as soon as a gas valve (not shown) is opened and the burner's ignition system is active, particularly even before gas flows. The ignition system can be connected to the valve or to a separate "start button," for example.

[0032] The substructure 3 serves, in the usual way, to accommodate gas cylinders, fittings, barbecue tools, dishes, etc.

[0033] Instead of metallic side walls 11, the substructure 3 can, for example, also be equipped with a textile covering.

[0034] Below the handle of the hood 2, a flat base 5 made of metal or aluminium is arranged as a working surface, on which a solid extendable table 6 is arranged to the left and / or right of the combustion chamber 4 ( Fig. 1) This extendable table 6 is guided by guide rails 8 and an integrated internal guide in the base 5 ( Fig. 2) and can thus be easily extended and retracted horizontally. The guide rails 8 are designed as tubular profiles in this example. Intermediate pieces 7 can be clipped into place when the table is extended. To retract the extendable table 6, the intermediate pieces 7 are unclipped and can be suspended from under the extendable table 6 by means of magnets.

[0035] The extendable table 6 can be locked to the base 5 in a manner not shown. Hooks 9 for hanging barbecue utensils, gloves, etc. are advantageously arranged on the outer end face of the extendable table 6.

[0036] Instead of the extendable table 6, an additional burner 12 according to the invention in the form of a box-shaped heat diffuser kit 12 ( Fig. 3) are arranged at base 5.

[0037] The additional burner 12 is also attached to the base 5 by means of fixed guide rails 8 on the base 5.

[0038] An additional burner 12 in the form of a Blazining Zone Kit, on the other hand, comprises an open chamber 13 in which a ceramic burner 14 is arranged, covered by a grate 16a whose height is adjustable above the ceramic burner 14. A grate-like heat diffuser 15 can be arranged between a grate 16b and the ceramic burner 14, the surface of which in the area of ​​the ceramic burner 14 is designed as a sheet 17 (tamper plate) and is thus closed. The adjoining outer areas are provided with slots 18 ( Fig. 4).

[0039] Grate 16a is height-adjustable. Grate 16b rests fixedly on frame 13. Grate 16a is lower than 16b.

[0040] The additional burner 12, as a Blazing Zone Kit, enables high-heat grilling at temperatures of 600°C-900°C, resulting in a perfect crust on the meat. The heat diffuser 15 is removed for this purpose ( Fig. 4a).

[0041] On the other hand, the additional burner 12 with inserted heat diffuser 15 enables regular grilling at medium temperatures of 200°C-350°C and is particularly suitable for fattier meats and more sensitive grilled foods such as poultry, fish or vegetables.

[0042] The sheet metal 15, 17, 18 covering the ceramic burner 14 ( Fig. 4b) prevents grease fires and, in conjunction with the slots 18, distributes the heat across the grill grate 16b. Grease or other liquids flow through the slots 18 into the drip tray without reaching the ceramic burner 14 and are collected in the tray 13. The Heat Tamer is also positioned at an angle to allow grease to drain off the grooves.

[0043] Heat diffuser 15 and grate 16a and 16b can in turn be cleaned individually by hand or in a dishwasher.

[0044] Instead of or in addition to the auxiliary burner 12 in the form of a Blazing Zone Kit, another auxiliary burner 22 in the form of a Cooking Zone Kit is located at base 5 ( Fig. 5) can be arranged, which can be attached to the base 5 like the Blazing Zone Kit.

[0045] A Cooking Zone Kit comprises a housing 23 with a removable pan 24 arranged within it, a centrally located gas burner 25, and a height-adjustable cast iron ring rack 26. The gas burner 25 is operated by means of a rotary knob 28, which is located on the front of the housing 23 ( Fig. 5).

[0046] For high heat for quickly searing meat, fish or vegetables, the ring rack is 26 deep, i.e. located near the pan 24 ( Fig. 6a). For medium heat (searing meat, fish or braising), the ring rack 26 can be adjusted to a medium height ( Fig. 6b). For lower heat (for example, cooking sauces or soups, braised and rice dishes), the ring rack 26 is in a high position ( Fig. 6c) adjustable.

[0047] For example, Blazingzone Kit 12 and Cooking Zone Kit 22 can also be combined into one unit and arranged on the Base 5 ( Fig. 7) This unit can also be covered by a Plancha 20, which can be divided into heat zones that can be controlled separately.

[0048] Likewise, instead of the additional burner 12, 22, a second extendable table 6 can also be locked to the base 5.

[0049] Furthermore, a gas cylinder kit 19 can also be installed at base 5 ( Fig. 8) be able to be arranged for a larger gas cylinder, e.g. for 11 kg of gas.

[0050] Additionally, the grill could also be used with a grill grate pizza stone kit 21 ( Fig. 9) be equipped, which, when not in use, can be stored on a side wall 11 of the substructure 3.

[0051] Instead of a burner arrangement of a gas grill, electric heating elements can also be used as a heat source; with appropriate design modifications, charcoal, briquettes, pellets or other combustible organic materials can also be used.
