The invention relates to a fireplace according to the preamble of claim 1. Such fireplaces have means for receiving a heat source, such as an electric heating coil or fossil or lumpy, carbon-containing fuels, such as wood, charcoal, charcoal briquettes, coal and the like. These heat source receiving means are usually supported by a base, whereby it is understood that this base can also be formed in one piece with the heat source receiving means.

In particular, the invention relates to the field of application of generic fireplaces that radiate heat onto a grill. Consequently, the invention relates to the field of application of grills, in particular swivel or pendulum grills, rotary grills or rotisserie grills.

In order to simplify the manufacture and design of fireplaces of this type, the invention provides a fireplace in which the heat source receiving means comprise a substantially bowl-shaped, preferred

This makes it particularly easy to provide heat source absorption means. Since such standard pressed bases or discs are manufactured in large numbers, such heat source absorption means are also cost-effective. Furthermore, such standard pressed bases or discs require an attractive, shapely appearance, particularly from the point of view of "technical aesthetics".

The term standard pressed bottoms or discs includes, among others, solid bottoms, deep-domed solid bottoms, dished bottoms, basket-arch bottoms, elliptical bottoms, hemispherical bottoms, plate bottoms, flat bottoms and domed discs.

By means of such standard pressed floors or discs, it is possible to arrange the foot - as preferred - only in a central area, i.e. close to the center of the floor or disc and to connect it to the floor or disc, i.e. to make the floor or disc self-supporting.

In particular, a dished bottom can be provided as the heat source receiving means. This has sufficient depth to secure the fireplace at the sides, in particular against wind influences, without the heat source receiving means being too deep and either the heat source being arranged too deep in the heat source receiving means or too much free space remaining under the heat source.

Dished ends also have the dimensional rigidity desired according to the invention.

In particular, it is advantageous to make the standard pressed base or disc out of stainless steel. The reflectivity of the stainless steel improves the efficiency of the fireplace. On the one hand, this makes the heat source

itself, due to the heat rays it emits, and on the other hand, the heat energy radiated downwards, which would otherwise be lost, is reflected upwards, in the direction of any grilled food surface, thus achieving a higher temperature on the grilled food surface.

Since stainless steel is a relatively poor heat conductor, the fireplace is better insulated against downward heat radiation due to the use of this material as a heat source absorber than when using other metals, which also increases the efficiency of the heat source. It goes without saying that the design of the heat source absorber made of stainless steel can also be used advantageously without the use of the standard pressed base or disc according to the invention due to its positive influence on the efficiency of the fireplace.

In particular, a wear plate can be arranged, preferably approximately halfway up the shell depth of the standard press base or disc, on which the fossil or lumpy, carbon-containing fuels are arranged. In particular, this wear plate can have openings through which spent fuel can be removed from the heat source. It goes without saying that instead of a wear plate, which is also preferably made of stainless steel, other means for supporting a heat source, such as a grate, can also be provided.

An ignition heater, such as an electric heating coil, can be arranged within the heat source and/or on the wear plate as a fireplace or grill lighter.

To make cleaning the fireplace easier, it can have means for tilting the heat source holder relative to the base. In this way, unused fuel or burned fuel can be easily removed from the heat source holder. In particular, it is also possible to sweep out the bowl-shaped standard pressed base or disc in this way.

Furthermore, especially if the heat source is electrically operated, the tilted standard pressed base or disc can be used as a reflector for a heater, e.g. for heating a seat or a seating area. It is also conceivable, for example, to provide a carrying device for lumpy, carbon-containing fuels that allows the heat source receiving means to be tilted without the unburned fuels leaving their position in relation to the heat source receiving means (i.e. falling down).

In particular, the tilting means can comprise a hinge. If this hinge has a removable hinge pin, it is possible to remove the heat source receiving means from its base in a particularly simple manner and, for example, to stow it away or to provide it with a different base. Due to the advantages mentioned above, it is clear that the use of tilting means, in particular a hinge or even an unlockable hinge, between the heat source receiving means and the base can be used advantageously in fireplaces of this type, regardless of the other features disclosed.

To make it easier to manufacture the base, it can also include a standard pressed base or disc, preferably rotationally symmetrical. This also reduces the costs of manufacturing such a fireplace while maintaining a particularly high level of stability and serves an aesthetic purpose.

see aspects. In particular for aesthetic reasons, it is advantageous if the base has a standard pressed base or disc with an essentially bowl-shaped cross-section that is open at the bottom, preferably a dished base or a curved disc. This can be closed at the bottom by a flat base that is open at the top or a flat disc. Such a base, which can also be used advantageously independently of the other features disclosed or claimed, creates the possibility for the first time of compact and weatherproof accommodation of drive means and the like (including electrically operated units).

In order to adjust the height of the heat source holders, a support tube can be provided under the heat source holders, which stands on the upper standard pressed base or disc of the base and supports the heat source holders. The base can also be made of stainless steel, for aesthetic reasons among other things.

In order to further increase the efficiency of the fireplace, the fireplace can comprise means for generating an air flow from the heat source receiving means through the heat source or directly past the heat source. Such an air flow is usually directed in the direction of the main radiation direction of the fireplace. This air flow makes it possible to transport the air heated in the vicinity of the heat source directly in the heating direction and not just to use the temperature-related movement of the air. Such a fireplace is therefore similar to the principle of a hot air oven. In particular, such a fireplace, which is arranged tilted, e.g. for heating a seating group or a seat, creates a significantly more pleasant climate, since warm air is transported to this seating group or seat.

Furthermore, the increased oxygen supply can increase the temperature of the heat source or make it easier to ignite it. It goes without saying that these air flow generation devices can be used independently of the use of the standard press base or discs.

The air flow generation means can comprise, for example, a nozzle or nozzle ring arranged within the standard press base or disk, through which air can be blown to the Ii? heat source. In particular, this nozzle or nozzle ring can be arranged below the wear plate.

To facilitate the handling of the air flow distribution and the fireplace, a fan with an air duct can be provided in the base so that the fan can accelerate air in the direction of the heat source. In particular, this air duct, e.g. designed as a pipe or hose, can connect the fan to the nozzle or nozzle ring.

To use a fireplace according to the invention as a grill, while at the same time being compact, it is advantageous if the base includes means for supporting the grilled food support. Such support means can, for example, include a bracket that extends from the base to above the fireplace and from which the grilled food support hangs by means of a tensile holding means, such as a rope, a steel cable or a chain. These support means of the grill support formed on the base can be used advantageously regardless of the use of standard pressed bases or discs. In particular, this enables the heat source support means to be independent of the grilled food support or the support means if the heat source support means are to be moved independently of these.

• *

·

The length of the tensile holding means can advantageously be adjustable in order to control the height of the grilled food support above the fireplace.

By means of deflection means, the tensile holding means can be guided from its point of application on the holding bracket to the foot. Means for shortening the tensile holding means can be provided in the foot. This enables a compact design, as there is free space available in the foot, and also increases stability, as the weight of the foot increases or the center of gravity shifts downwards.

It can be advantageous to provide an electrical voltage source or an electrical power supply in the base. In particular, this can be done by connecting it to the 220 V network. The electrical energy can be used in particular to operate the fan, the ignition heater and the means for shortening the pulling holding means or the cable winch. In particular, however, an electrical connection for a lamp, an electrical rotisserie device or an electrical rotary drive for the grill support can also be provided.

It is also conceivable, for example, to support the grilled food support by means of a vertical support rod arranged centrally in the base and the heat source receiving means. On the one hand, in this case, means for adjusting the height of the support rod or the grilled food support as well as means for rotating the support rod or the grilled food support can be provided in the base.

The above-mentioned components, as well as those claimed and described in the embodiments, to be used according to the invention are not subject to any restrictions in terms of their size, shape, choice of material and technical conception.

special exceptional conditions, so that the selection criteria known in the respective area of application can be applied without restriction.

Further details, features and advantages of the subject matter of the invention emerge from the following description of the accompanying drawing, in which - by way of example - a preferred embodiment of a fireplace according to the invention is shown. In the drawing,

Fig. 6 the wok pan according to Fig. 3 in side view; and

Fig. 7 shows the wok pan according to Fig. 3 in top view.

As shown in Figs. 1 to 3, the fireplace has heat source receiving means 1 with a dished bottom 10 that is open at the top and a base 2. The base comprises a dished bottom 20 that is open at the bottom and is closed with a flat bottom 21, e.g. with a circumferential weld seam. Under the flat bottom 21 there are height-adjustable support feet 27 that ensure that the fireplace stands stable.

The base 2 also has a support tube 22 which is arranged centrally on the dished base 20 and on which the dished base 10 rests centrally.

The dished bottom 10 is connected to the support tube 22 via a hinge 12. By removing the hinge pin, the dished bottom 10 can be removed from the support tube 22. To make working with the dished bottom 10 easier, a surrounding handrail 11 designed as a railing is provided on the upper edge of the dished bottom 10. This handrail 11 can also serve as a holder for various grilling equipment and cooking accessories. In particular, a rotisserie device can also be attached to this handrail 11. The surrounding railing stiffens the bottom edge against elastic deformation.

A wear plate 3 is arranged approximately halfway up the curvature of the dished bottom 10. The heat source, e.g. charcoal, is arranged or placed on this wear plate 3. Furthermore, a ring-shaped, electrically operated ignition heater 30 (see in particular Figures 4 and 5) is provided on the wear plate 3. To start up the fireplace, the fuel, e.g. charcoal, is placed on the wear plate 3 and the ignition heater 30 is heated until it reaches a temperature at which the fuel ignites and burns off on its own.

Furthermore, the wear plate 3 has openings 31 (numbered as an example) through which spent fuel is removed from the heat source. In order to prevent the wear plate from bending too much, the wear plate 3 has radially arranged reinforcing ribs 32.
35

A support edge 33 is arranged radially around the wear plate, which ensures that the wear plate 33 is securely supported in the dished bottom 10.

A grill 5 is arranged above the dished bottom 10, which is suspended by means of eyelets 50 from tensile holding means 24 (shown in dash-dotted lines). The tensile holding means 24 are guided through an opening 28 into the interior of the holding bracket 23 and pass through the holding bracket 23 by means of deflection rollers 26 to a winch 25 arranged in the base 2 or in the space formed by the dished bottom 20 and the flat bottom 21. In the present exemplary embodiment, the tensile holding means 24 is designed as a chain outside the holding bracket 23 and as a steel cable inside the holding bracket, in particular also on the winch 25, so that the fireplace has an aesthetic appearance, but as far as possible a high degree of ease of movement of the winch 25 is ensured. To increase the swiveling ability of the grill 5, the elastic holding means 24 have a rotary joint 29.

In the present embodiment, the retaining bracket 23 consists essentially of a tube bent into an approximately C-shape, which is closed at its ends by small dished ends 23'. Of course, other shapes of a retaining bracket 23 according to the invention are also conceivable.

A nozzle ring 40 is arranged in the dished bottom 10 below the wear plate 3. This is connected by means of a hose 41 forming an air channel to a blower 4, which is arranged in the foot 2 or in the space formed by the dished bottom 20 and the flat bottom 21. The dished bottom 20 has an air inlet 42, through which the blower 4 can suck in air and expel it through the hose 41 and the nozzle 40 as well as the openings 31 of the

·

wear plate 3 to the heat source or fuel.

To operate the fan 4, the ignition heater 30 and/or the winch 25, the fireplace has a mains connection by means of a mains cable 6. Starting from this mains cable 6, further mains connection options (not shown) are provided on the fireplace, which can be used, for example, to connect a rotisserie device or a lamp.

Furthermore, an operating console can be provided on the fireplace, with which the electrical devices, such as the fan 4, the ignition heater 30, the winch 25, but also the connections for the rotisserie device or the lamp, can be operated. To increase the user-friendliness, this console can be arranged on the support bracket 23, in particular at approximately chest height.

In order to ensure that the fireplace can be used comfortably even in the dark, it is also conceivable to provide a lamp on the support bracket 23, in particular instead of the upper dished bottom 23''.

As shown in Figures 3, 6 and 7, other cooking devices can be attached to the tensile holding means 24 instead of the grill 5. In particular, it is advantageous to also form such cooking devices from standard pressed bases or standard pressed disks. As shown in Figures 3, 6 and 7, for example, a wok pan can be formed from a curved disk. Such a curved disk 51 also has holding eyes 50 which serve to attach it to the tensile holding means 24. Furthermore, the curved disk 51 or the wok pan has handles 52 for easier handling.

Similarly, plate bottoms or flat bottoms can be used to form pans, edged perforated sheet metal to form a

Warming bases or dished or elliptical or hemispherical bases are used to form kettles or pots. Furthermore, such bases, in particular a hemispherical base, can be used as a braising lid - to form a kettle grill. Independently of a fireplace according to the invention, such cooking devices or equipment can be used advantageously, as they are relatively inexpensive to manufacture and are also extremely aesthetically pleasing. In particular, it is recommended that such cooking devices or equipment be made of stainless steel, as this is easy to clean, has an attractive surface and is relatively insensitive to external influences.

It is also conceivable to attach a heat reflector above the heat source receiving means 1, which reflects the heat emanating from the heat source, e.g. onto a seating group. In particular, a stainless steel sheet can also be provided for this purpose. Such a heat reflector can also be attached to the tensile holding means 24.
