Description

The present invention relates to an ignition chimney with a tubular base body which is connected to a base via a gas-permeable base plate, the base including an air intake chamber and the base body including an annealing chamber in which lumpy firing material can be made to glow.

Such a chimney starter is generally known from the prior art. This has an annealing chamber into which charcoal or grill briquettes are added. An air intake chamber is formed in a base, in which lighting material, such as newspaper or wood chips or lumpy grill lighter, can be accommodated. The base is provided with peripheral holes. When the material to be fired is in the glow chamber and lighting material is arranged in the air intake chamber, the lighting chimney is placed on the bottom of a grill and the lighting material is ignited through the openings in the base. The hot air in the air intake chamber rises through a perforated base plate and through the spaces between the items to be fired, while fresh air from the surroundings is drawn in through the base. In this way, the material to be fired in the annealing chamber gradually begins to glow from bottom to top. When the glowing state of the items to be fired has progressed sufficiently, the ignition chimney is lifted by a handle and the glowing items to be fired are tipped onto the bottom of the grill appliance. If required, additional items can be added to the already glowing items, which will then also begin to glow as the process progresses.

"Starting up" a grill always requires a considerable amount of lead time. The participants in a barbecue must be patient until the food in the grill has reached the right heat and grilling can begin. The length of the lead time not only depends on the skill of the griller, but also depends on the wind conditions, the location of the grill and the outside temperatures. Nevertheless, long lead times are regularly charged to the griller.

The object of the present invention is therefore to develop an ignition chimney of the type mentioned at the outset in such a way that the lead time from lighting to the start of the grilling process on a charcoal grill can be significantly shortened.

The object is achieved in that a fan device generating an air flow is integrated in the base body.

The installation of a fan device in an ignition chimney enables better oxygen distribution in the material to be fired, so that the glowing of the material is optimized throughout the entire glow chamber.

Another advantage of the present invention is that the fan device is automatically activated by rising air warmer than the ambient air. The fan device is thus activated by thermal convection and influences the thermally induced rising air in the annealing chamber. As a result, the fan device can be operated without electrical energy.

Another advantage of the present invention is that the fan device has a first fan element which is arranged between the air intake chamber and the base plate. This ensures that the rising air is influenced before it enters the annealing chamber.

Another advantage of the present invention is that the fan device has a second fan element which is arranged at an end of the glow chamber opposite the base plate. The second fan element ensures that the rising air is better extracted from the glow chamber. So while the first fan element pushes air into the glow chamber, the second fan element pulls air out of the glow chamber. This significantly increases the proportion of oxygen required for the annealing of the material to be fired in the annealing chamber.

Another advantage of the present invention is that the first fan element and the second fan element are each rotatably mounted. The rotatable mounting of the first and second fan elements swirls the air in the glow chamber. This also optimizes the air flow path through the items to be fired. More surface areas of the material to be fired are flowed around in a shorter time.

Another advantage of the present invention is that the base body has a gas-permeable cover for covering the glow chamber at an end opposite the base and the second fan element is arranged in the cover. Due to the arrangement of the second fan element in the cover, it can be relatively easily removed temporarily from the glow chamber in order to tip the glowing material to the bottom of the grill after the initial glow.

It is advantageous here that the cover is connected to the glow chamber via a hinge. After the end of the glowing process, the cover can simply be connected to the second fan element 1 after can be folded up and clear the way to tip the glowing firing material out of the annealing chamber.

Further advantages of the present invention emerge from the further features of the subclaims.

An embodiment of the present invention is described in more detail below with reference to the drawing. Show it:

• 1 a schematic view of a chimney starter according to the present invention;
• 2 a schematic plan view of the chimney starter 1 ; and
• 3 a schematic view, partly in longitudinal section, of the ignition chimney 1 with partially open lid and broken base plate.

In 1 Figure 4 is a schematic view of a chimney starter 1 illustrated in accordance with the present invention. The chimney starter has a base body 3 on that one pedestal 5 and an annealing chamber 7th includes. In the base 5 is an air intake chamber 9 educated. The base 5 has air intake openings on its circumference 5.1 on. The air intake openings 5.1 are over the entire perimeter of the base 5 distributed. In the present embodiment, the air intake ports are 5.1 round, in other embodiments the air intake openings 5.1 also have any other contours.

On one of the pedestals 5 opposite end of the annealing chamber 7th is a lid 11 arranged. The lid 11 is at the top 7.1 the annealing chamber 7th hinged. The lid 11 is in 1 in the closed position. On the side of the body 1 is a handle device 13 appropriate. The handle device 13 is preferably thermally insulated from the base body and also with the cover 11 connected so that this over the handle device 13 can be brought into an open position and / or closed position.

In 2 FIG. 12 is a schematic plan view of the chimney starter from FIG 1 shown. The top view shows that the lid 11 a vertical through hole 15th having. The vertical through opening 15th In the embodiment shown, it has an opening cross-section that is only slightly smaller than the diameter of the lid 11 so that the lid 11 the through opening 15th with only a narrow lid edge 11.1 limited. In other embodiments, the through opening 15th also have a significantly smaller opening cross-section in relation to the cover surface. However, this can have a negative impact on the air flow, so that the largest possible passage opening is regularly available 15th is sought in relation to the cover surface.

In the through opening 15th is a fan device 17th used. The fan device 17th is also in 3 additionally shown. The fan device 17th comprises in the present embodiment a first fan element 17.1 ( 3 ) and a second fan element 17.2 ( 2 ). The first fan element 17.1 and the second fan element 17.2 can be designed identically, but can also have different geometries in order to influence an air feed. In other embodiments, the fan device comprises 17th only a first fan element 17.1 and no further fan element 17.2 . Again in other embodiments, more than two fan elements can also be in the fan device 17th be included.

In the present embodiment, the fan device is now 17th with the second fan element 17.2 in the lid 11 recorded. The second fan element 17.2 sits in the air passage opening 15th and is rotatable around a shaft 19th ( 3 ) stored. Also the first fan element 17.1 in 3 is in the present embodiment on the shaft 19th attached and thus rotatably mounted.

The through the air intake openings 5.1 in the base 5 sucked in air flows through the air intake chamber 9 up and offsets the first fan element 17.1 in rotation. This will force more air through the air intake openings 5.1 into the air intake chamber 9 sucked up. The first fan element 17.1 so presses the air into the glow chamber 7th . Due to the rotation of the second fan element 17.2 at the upper end 7.1 the annealing chamber 7th becomes the one in the annealing chamber 7th air rising upwards out of the annealing chamber by thermal convection 7th pulled out.

The first fan element 17.1 sits between the annealing chamber 7th and the base 5 in a receptacle 21st that goes up through a gas-permeable base plate 23 from the annealing chamber 7th is delimited. The gas-permeable base plate 23 is a perforated plate in the present embodiment. The receiving chamber can go down 21st to the base 5 be open to it. In other embodiments, the receiving chamber 21st but also to the base 5 have facilities to place material of a grill lighter on it.

The lid 11 is about a hinge 12th with the handle device 13 connected.

In 3 is shown schematically how the lid 11 is brought into an open state. In addition, the annealing chamber is 7th shown in longitudinal section. Immediately below the base plate 23 (which is shown broken here) is the first fan element 17.1 with the wave 19th connected. With the lid open 11 is the first fan element 17.1 not with the second fan element 17.2 in contact. Only in the closed state in 1 the second fan element connects 17.2 with the wave at the top 7.1 the annealing chamber 7th so that the two fan elements can then rotate together around the shaft.

In the embodiment shown, the ignition chimney is cylindrical. However, the ignition chimney according to the invention is not limited to a cylindrical shape. So can the shape of the annealing chamber 7th be independent of the shape of the fan elements. The fan elements 17.1 and 17.2 can, for example, be round, while the base body 1 is designed with an angular contour.
