Definitions

• the invention relates to a grill, in particular a charcoal grill, comprising a housing with lateral outer walls, which in turn preferably each have an outwardly curved area, a grill grate, a fat collecting trough arranged below the vertical projection extending from this plane and laterally from its vertical projection Projection arranged coal receptacles as well as pivotable wall sections of the lateral outer walls running above the coal receptacles obliquely to the grillage, wherein along the oblique wall sections run on the inside and at a distance from these guide plates.
• a corresponding charcoal grill can be found in DE 297 15 854 Ul.
• the inclined housing walls in the interior of the housing start from which hot air guide channels are formed, through which a substantial part of the air flowing through the coal receptacles and heated by the glowing coal is guided.
• the outer surface of the housing is heated to such an extent that the risk of burns can arise.
• Grills with receptacles for coal arranged laterally to the food to be grilled can also be found, for example, in US Pat. No. 3,743,838, WO 87/05197, US 2,891,465 and DE 195 15 080 AI. It is also known to provide a grill with an attachment which has a horizontally guided drive chain which can be driven by a drive motor and which in turn meshes with gearwheels emanating from grill spits (DE 297 15 564 Ul). Corresponding attachments or rotating arrangements to be used for the automatic turning of goods to be grilled can also be found in DE 78 18 174 Ul, DE 88 17 194 Ul, DE 29 33 603 AI or FR 2 722 966 AI.
• the present invention is based on the problem of developing a grill, in particular a charcoal grill of the type mentioned at the outset, in such a way that when an optimal grill result is achieved it is excluded that the outer walls are heated to an undesirable extent.
• the grill should have a simple construction, and the coal pick-up should be refilled without difficulty.
• the problem is essentially solved in that the coal receptacle is surrounded by an air guide hood which surrounds the guide plate and which completely or almost completely shields the coal receptacle from the lateral outer wall.
• Completely or almost completely means that the outer wall is adequately shielded from the coal receptacle without the air guide hood completely covering the coal receptacle from the outer wall sections of the grill in both vertical and horizontal projection.
• the air guide hood can consequently only extend essentially from the upper edge region of the coal holder in the direction of the grillage.
• the air guide hood consists of a first guide plate running along the outer surface and below the coal holder and a second guide plate that covers the coal holder on the top side and can be swiveled towards it, which extends along the likewise pivotable wall section that runs obliquely towards the grill grate.
• the second guide plate can be articulated on its side to an intermediate wall or a frame having through openings.
• the second guide plate which extends from the coal receptacle like a coal basket and extends along the outer wall that slopes at an angle to the grillage, is double-walled.
• the second guide plate can comprise two plate elements running parallel or largely parallel to one another, which preferably have a distance between 5 to 15 mm, in particular of approximately 10 mm.
• a corresponding duct provides rear ventilation or air circulation, which causes thermal insulation.
• the outer wall can also be double-walled in order to achieve additional insulation.
• heating of the housing is reduced to such an extent that there is no risk of burns.
• the casing of the charcoal grill is only warmed up to a maximum of about 50 to 60 ° C.
• the relevant charcoal grills according to the prior art have outside housing temperatures of up to 300 ° C. without further ado.
• the channels and the double walls through which they can flow provide rear ventilation or the creation of an air curtain.
• the double wall is designed such that the sheets forming the double wall are spaced apart from one another on the bottom side and merge into one another at the head side, with passage openings being provided in this area. This also results in an air flow within the double wall, which also causes cooling.
• the carbon intake is compared to the housing outer wall via the air guide hood, that is to say the first and second guide plates are shielded, so that, in deviation from the known prior art, air flowing through the coal intake does not reach the housing side wall directly.
• this is insulated with the result that the housing wall does not heat up undesirably.
• the outer wall of the housing is quasi double-walled in the area of the coal holder.
• the pivotable outer wall section, via which a carbon holder is accessible essentially has only a covering and not a shielding function.
• the first baffle running along the outer wall side area and preferably at least in sections along the bottom area of the coal receptacle brings about a targeted supply of air through the coal receptacle while at the same time shielding hot air from the outer wall.
• the first guide plate can also extend at the front along the coal receptacle.
• the end faces of the coal receptacle can be covered by closed elements, such as metal sheets, which emanate therefrom.
• a ventilation channel formed.
• it has a larger cross section below and in the area of the coal intake than above it.
• the second baffle is hood-shaped and opened towards the inside of the grill so that hot air can flow towards the grill grate.
• the outer side wall of the grill housing itself is protected against both hot air and heat radiated directly from the charcoal.
• the end walls of the grill are also shielded, on the one hand by the side faces of the hood-shaped second guide plate and on the other hand by the covers of the end faces of the coal receptacles.
• the partition itself preferably consists of or comprises expanded metal mesh. This ensures that hot air can flow to the grillage to the extent necessary without the risk of any sparks flying to the food being grilled.
• the intermediate wall itself preferably extends in the area and at the height of the coal receptacle, with each coal receptacle being assigned an intermediate wall, so that the area below the grillage is shielded from the coal receptacles.
• the partition wall run almost or approximately over the entire height of the housing. Regardless of this, the respective partition wall extends perpendicular to the plane spanned in front of the grillage.
• an attachment can be placed on or replacing the grillage with an attachment that can be driven by a drive with grill spits or sections such as gears of this intermeshing chain, which in turn leads to longitudinal attachment walls running parallel to one another via deflection rollers is led.
• at least one of the longitudinal side walls running parallel to one another has at least one cutout having a section bent in the direction of the other longitudinal side wall, which forms a support for the chain.
• the inner longitudinal side wall have two cutouts which run parallel to one another and parallel to the plane spanned by the upper edge of the attachment and are bent in the direction of the further longitudinal side wall to form supports for the upper and lower chain section.
• the supports have a depth that is equal to or approximately the same as the distance between the side walls.
• At least the upper support can consist of sections spaced apart from one another. In the areas where the chain is not supported, the sprockets or gearwheels emanating from the spikes engage the chain itself, so that a secure gripping is ensured.
• At least one of the deflection rollers is adjustable and thus performs the function of a chain tensioning element.
• one of the deflection rollers such as gearwheels starts with a shaft which can be actuated by a drive which in turn has a housing with a projection on the attachment which engages in a receptacle which acts as an abutment from the upper edge of the at least outer longitudinal side wall.

• the fat collecting pan 29 does not prevent the ash from sliding down, it is adequately spaced apart from the guide elements 35, 37. This ensures that the ash reaches the ash pan 27 in a targeted manner and the fat only in the fat collecting pan 29.
• the coal receptacle 32 is designed as a basket which consists of rods which run perpendicular to one another and are welded to one another and which are provided with the reference numerals 34, 36 purely by way of example.
