FR2583145A1 - Rapid igniter for hearths - Google Patents

Abstract

The invention relates to a hot air generator capable of igniting all combustible materials and especially for igniting fires for fireplaces, barbecues or the like. This generator is composed of a casing 2 inside which a cone concentrates the cold air sent by a fan motor 3 through a tube containing heating electrical resistors. The tube is placed under the hearth to be ignited. This generator is used in all households.

Description

The present invention relates to a hot air generator capable of lighting all combustible materials, and in particular for lighting fireplaces or barbecues
Indeed, until now the lighting of a chimney fire presents difficulties for the lighting because it is necessary to place under the logs inflammable materials of small volume, like crumpled sheets of paper, small wood, brush, where the disadvantage of this traditional firing process; indeed, at the start of combustion there were, depending on the importance of flammable materials, sudden and uncontrollable large fire developments with risk of accident, especially by fire from the chimney flue or from the fall of these burning materials on the parquet floor and also the risk for some people with no experience of projecting onto the fire that is believed to be extinguished - a highly flammable product such as alcohol, methanol, petrol, petrol, etc. ..

The object of the present invention is to eliminate all these drawbacks: it allows immediate ignition, even if the logs or the woods have stayed in the rain;
The operating principle is as follows - hot air at 500/600 centigrade is sent on the basis of the materials to be ignited (even humid), initially this hot air ventilated and directed, superficially dries an area in the materials to ignite, after this drying time, the surface parts start to ignite and develop quickly thanks to the ventilation of the hot air, the flame develops and the air can at this time stop the supply of the heating resistors of this generator, and leave only the ventilation on
This hot air generator consists of several elements.

 -an electrical resistance (5) wound on a ceramic support and protected by an external sheath.

 - A motor-fan (3) projecting the outside air through the coils of the heating resistance.

 -A start-up key (I6) and fan position and power-on position of the heating resistors (I8) in this case a red control light remains on (I7).

-A support and orientation device (8) allowing the device to be adjusted in height so as to adapt to the different types of hearths as well as the possibilities of adjusting the orientation angle
- A protective nozzle (6) resistant to the action of flames.

 - A protective casing (2) for the motor-driven fan assembly and internal electrical wiring.

Of course, the invention will be better understood by referring to the drawings and the description given here only as a non-limiting indicative diagram and are subject to numerous variants of embodiments and applications, rubber produced.
New industrial.

 The FIG- I - represents as a whole the generator proper "lighters" mounted on telescopic foot (8) allows -unt its application according to the type of hearth to ignite.

In (9), locking screw. In (7), the pivot axis of the telescopic leg for storage. In (5), the electrical resistance.

suitable heating. In (3), the electric motor fitted with its propeller (4), projecting the outside air through the turns of the heating resistance. In (I8), the red light. In (i7), position of a thermostat cutting the action of the heating resistors and the ventilation, or vice versa, for example.

 The cold air coming from outside through openings made in the casing (2) is sent into the insulating tube (I) introduced under the hearth, air, which passing between the resistors heats up and allows the general ignition of the foyer.

 FIG - 2 - represents a ceramic tube (I) or insulating material resistant to high temperatures in which the resistors will be placed (5), this removable tube of appropriate length is instantly fixed, by screwing or bayonet fitting so that the pins (I0) of the electrical contacts contact the internal pins (IO) of the generator. In (6), the removable nozzles screwed at the end of the tube (I), and resistant to the high temperatures of the hearth.

 FIG-3- represents, seen internally at the end, the cbne of concentration of the cold air sent in the tube (I). At the end of the generator cone (2) an insulating washer (II ') will receive the electrical contacts (10), in correspondence with those of the tube (I).

 FIG. 4 - shows in variant and in plan the casing of the double-walled generator containing an isothermal insulator (II ') resistant to high temperatures and its rear socket (I5 allowing access to the motor and to the wiring devices, timer, thermostat or other that is needed for the proper functioning of the device.

 FIG- 5 - represents, seen in profile, as a variant, another device, the motor (3) of which is placed outside the housing (2) on an articulated harness (9), This motor is fixed only during use by inserting the axis into the sleeve (I3) and locked in (I4), by a screw or knurled button. In (I2), handle giving access to the interior of the generator. In (8), the telescopic support leg.

 The invention is not limited to the embodiment shown and described, but elXe can vary in model, material, dimensions without altering the aim of the invention, the whole being to remain within the framework of the idea new subject of this patent.
