Definitions
- the present invention relates to a grate according to the preamble of claim 1 and a grill with the grate.
- a grate according to the preamble of claim 1 is known from US 8,544,382 B2.
- the object is achieved in that the main body of the rods of the known grate are coated with a coating.
- ceramic has distinct advantages over conventional base materials for bars of a grill grate. Unlike stainless steel, ceramic is clear less expensive and, unlike cast iron, it does not have to be baked first in order to form a protective layer. In addition, the heat storage capacity of even very cheap ceramics with that of cast iron is comparable, so that can be produced with ceramic with reasonable time branded fried food. Although chrome bars are also known for rusting a grill, such grates are just dismissed as cheap by professional barbecues, because the coating peels off quickly.
- the glaze of the bars of the grate according to claim 2 is particularly favorable applied to the ceramic material and yet provides sufficient
- Claim 3 can compensate for side effects, such as a different temperature expansion between the base body and coating the rods to avoid, for example, cracking.
- the specified rust can be used in a grill according to claim 10.
- Fig. 1 is a perspective view of a grill
- Fig. 2 is a perspective view of a grate for the grill of Fig. 1
- Fig. 1 is a perspective view of a grill
- Fig. 2 is a perspective view of a grate for the grill of Fig. 1
- Fig. 3 is a perspective view of a bar for the grate of Fig. 2 show.
- FIG. 1 shows a perspective view of a grill 2.
- the grill 2 comprises a body 4 on which a grate 6 can be placed. Within the body 4 is in a visible manner, a heating medium, such as charcoal or firewood receivable. The heating means is burned and is a source of heat for the grate 6, so that it can be heated on this a not further illustrated fried food.
- the side of the grate 6 directed into the body 4 is hereinafter referred to as the heat receiving side 8, because there the heat of the heat source
- Heat source is delivered to the fried food.
- a distance of the grate 4 from the heat source in the body 4 is adjustable via a height crank 13.
- the interior of the body 4 is accessible, for example, to be able to track heating medium.
- a height of the crank 16 is about a crank 16, a height of the crank 16
- Grate 6 can be adjusted.
- the body 4 is held on four feet 18. At two of these feet 18 rollers 20 are rotatably supported in order to move the grill 2 mobile. For this purpose, the grill 2 is pulled on a pull handle 22.
- the grill 2 also has a storage rack 24, can be kept on the finished fried food further away from the heat source.
- On an upstanding from the body 4 storage table 26 unfinished roast can be stored before the roasting process.
- a storage grid 28 which is arranged from the perspective of the grate 6 below the body 4, heating medium can be stored.
- the body 4 can be closed by a lid 30 mounted on the body 4 in a pivotable manner.
- a cover handle 32 is fixed to the cover 30, which can be pulled down from the viewpoint of the grate 4 for closing the body 4 and can be pulled up to open the body 4.
- On the lid 30 are also closable vents 34, so if necessary, hot air from the interior of the
- Carcass 4 can be dismissed.
- Ash drawer 36 on which the burned heating medium collects in the form of ash.
- the ash drawer 36 can be pulled out of the carcass 4 by means of a pull handle 38 to dispose of the ash.
- the construction of grills, such as the exemplary grill 2 of FIG. 1 is well known and should therefore not be further deepened.
- FIG. 2 shows a perspective view of the grate 6 for the grill 2 of FIG. 1.
- the grate 6 comprises two support members 38 and a plurality of rods 40. As a multiplicity fifteen rods 40 are present in the present embodiment.
- the holding elements 38 are designed barkenformig in the present embodiment, so that they can record in addition to compressive and tensile forces and bending moments.
- the bar-shaped holding elements 38 are angled, here at right angles to the
- Bars 40 arranged. Specifically, the bars 40 are parallel to each other at a predetermined distance between the two beamformigen
- Holding elements 38 arranged and connected thereto.
- the connection can be arbitrarily seen by screwing, but also by positive locking.
- At their outer ends of the bar-shaped holding elements 38 by means
- Spannelelementen which are designed here in the form of threaded rods 42, connected to each other.
- the voltage is in this case produced by retaining nuts 44 which on a side opposite to the bars 40 of the
- bar-shaped holding elements 38 are screwed.
- the screw connection between the threaded rods 42 and the retaining nuts 44 dissolves can be screwed correspondingly on the side of the rods 40 to the bar-shaped retaining elements 38 lock nuts 46.
- the special feature of the grate 6 of Fig. 2 is that the rods are basically made of a ceramic material. This will be explained in more detail below with reference to FIG. 3, a rod 40 from the grate 6 in a
- Each rod 40 has a cylindrical base body 48 with two
- end faces 50 which are interconnected via a shell side 52.
- the shell side 52 of the base body 52 is in this case with a Coating 54 coated.
- recesses 58 are formed in an axial direction 56 of the rod into which, for example, not shown pins with or without thread or other fastening means can be introduced to secure the rod 40 to the support member 38.
- the two recesses 58 are over a
- the cylindrical base 48 is made of the above-mentioned ceramic material.
- a ceramic material a material with a high heat capacity should be used, which can also heat up accordingly well.
- an alkali aluminum silicate with the grate 6 shown in Fig. 2 was used as a ceramic material, an alkali aluminum silicate with the
- Designation C130 according to DIN EN 60 672 used. This is an alumina porcelain whose specific heat capacity is between 800
- the coating 54 was chosen so that the grate 6 on the one hand was easy to clean. On the other hand, when grilling, however, metal cutlery should also be usable without damaging the coating 54 in the form of scratches.
- a glaze had proved most suitable for this purpose. It was sufficiently heat-resistant enough to withstand the temperatures of grilling up to 300 ° C, but was also insensitive to scratches.
- the selected alumina porcelain for the base 48 has a middle one
- the glaze was a material with a
- Coefficient of linear expansion is selected in the region of the selected for the body 48 alumina porcelain.
- a device glass has proven to be suitable.
- the glaze was a borosilicate glass with
- the grate 6 could be heated without problem and a fried material cooked thereon. There were no cracks or scratches after use. The bars 40 of the grate 6 could be cleaned without residue.
- the cost of the grate 6 of FIG. 2 are well below the cost of a conventional stainless steel grate, which meets essentially the same requirements for cleanability and scratch resistance.
- the rod 40 of FIG. 3 can be coated fully coated. This not only has the advantage that when installing the rod 40 no consideration needs to be taken to which side of the rod 40 for
- Heat receiving side 8 and which must be directed to the heat release side 10.
- On the rod 40 to the heat receiving side 8 flowing down fat can not be absorbed at the heat receiving side 8 of the pores of the body 48. In principle, however, it would be sufficient to provide the rod 40 with the coating 54 only on the heat release side 10.
