"Device for lighting a charcoal grill without the additional use of separately flammable liquid or gaseous substances "

The invention relates to a device for lighting a charcoal grill without additional use of separately flammable liquid or gaseous substances such as alcohol, gasoline or the like., for small grill systems, especially for garden grill systems.

The increasing popularity of charcoal-fired garden grills has not only been extensive Initiated and accelerated developments of barbecue equipment, devices and accessories to a large extent, but also sources of danger of various kinds, their non-observance or their existence can involve considerable risks.

Nowadays it is only very seldom the case to use all kinds of garden waste as embers for grilling, because not only the taste of the grilled food is impaired, but also health damage can result from the consumption of these foods prepared in this way. A perfect grilling in garden grill systems is basically only possible with charcoal. Charcoal is made by dry distillation of wood. The remaining residue contains about 80 % C, 1 % to 3 % ash, 5 % to 8 % water and 12 % to 15% volatile components.

The relatively high position of the ignition point between 200 and 250 C makes it difficult to ignite this high-quality product Fuel. In general, there is a high preparation effort, since the charcoal is normally only graded can be ignited via a layer of paper and a thin layer of wood.

the normal bellows is used as an aid. With the given proximity to sockets it is partly naturalized, instead of the bellows an old, disused vacuum cleaner on the pale side to use. However, this use requires some skill, as the air flow usually cannot be given up completely, otherwise the pilot light will be blown out or blown away, whereby the Blowing it away can be relatively dangerous for the environment.

Aids, such as those with denatured alcohol or other X thanols or low are briquettes soaked in boiling hydrocarbons, provide valuable help here. The practiced level of complete burnout of these substances before the one to be grilled Well placed on the grate or the rotisserie spit in front of the embers wall, which is usually arranged vertically is, unfortunately, is not always adhered to, so that here, too, at least the taste is impaired can come.

The dangerous bad habit of "helping" with one In view of the number of accidents - sometimes with fatal consequences - pouring from the denatured alcohol bottle is only possible can be described as carelessness that cannot be outdone.

It is therefore an object of this invention to provide a device to ignite the charcoal lying on a grill according to the classification given at the beginning,

which is safe and quickly effective, as well as in connection with the grill system regardless of location can be used in any way.

The inventive solution to this problem provides that the charcoal resting on the grill is at least partially permeable to air from below by a fan through a Grill base can be ventilated, the fan being driven by a motor and the drive being independent of the mains or is designed to be independent of external forces.

The use of an air-permeable grill base enables the effective supply of additional combustion air from below into the charcoal pile. This means that the air is not as usual during the ignition process is sucked through the pile by the pilot flame, which initially burns with a lack of air must be, but is available with overpressure in the ignition area. The grid-independent or external power-independent Drive allows unrestricted mobile use of the device.

As part of the design of this device, it is provided that the air supply from the fan to the grill bottom opens via a pyramidal or conical extension that forms a distribution space.

For further distribution, it is provided that the distributor space is connected to a distributor trough, the clear dimensions of which essentially correspond to the air-permeable area of the grill base, is expanded.

The air-permeable area preferably extends over a substantial part of the width of the grill bottom.

As a result of this design, the air is preloaded practically constant over the ventilation width led into the pile, so that its one-sided ignition and an associated one-sided Burning of the coal is avoided.

To protect the drive parts and the fan it is provided that between the distributor space and the grill base or the distributor space and the distributor trough, a heat-insulating layer is arranged, wherein Usually an asbestos sheet is used for thermal insulation.

The grill bottom is in the area of the air duct perforated or in this area made of porous material manufactured. This enables even air distribution in the intended area.

The fan is usually battery powered Electric motor can be driven, with the 1 1/2 V mono cell normally used for spit drives as a battery Is used.

Since the power consumption is relatively low, the fan must normally be used to achieve an ignition 2 to If operated for 5 minutes, such a cell is sufficient for a whole year and the service life is Basically not determined by the consumption of energy, but rather by aging. Regardless, in Another embodiment provided that the fan can be driven by a windable spring motor.

This motor with a running time of usually 12 minutes is practical and also indestructible.

Overall concerned: is the device according to the invention to the full extent of the task, it enables, only when using one Piece of paper, e.g. a paper handkerchief, a safe and quick ignition of the coal pile and can be used in any way, regardless of location.

The device according to the invention is exemplified by the partial representation of a garden grill explained in more detail.

Figure 1 shows a section through the grill in his

A wider extension, the section through the center of the funnel-shaped distribution space and then offset, along the rear wall of the housing, so that the view of the battery, switch, Motor and fan assembly released from the reverse.

Figure 2 shows a section through the grill in its

Depth extension. The cut goes through the fan.

The housing 1 is designed to be open at the bottom and via a bracket 3 attached to a rear wall 2 of the carrier drivable by the direct current source, i.e. by the battery 5 held by a clamp 4, via a switch 6 Motor 8 and the coupled with it, from a cylindrical housing 9 with dixialem air inlet 10, tangential air outlet nozzle 11 and an impeller existing fan 13.

For the battery 5, the housing 1 is "minus" conductive and the cable 7 leading to the switch 6 is "plus" conductive.

The air outlet nozzle emerging tangentially from the fan 13 11 opens into the distributor space which is conically designed as part of the upper cover 14 of the housing 1 15, this distribution space 15 having a heat insulating Layer 17 (asbestos) through the distributor pan 16
