Description

TABLE GRILL

The present invention relates to a grilling device and more particularly to a table grill comprising a frame and a plurality of grilling rollers arranged substantially parallel to one another in the frame, which are rotatably mounted about their longitudinal axis, and a drive for rotating the grilling rollers about their respective longitudinal axis.

Such grill devices are known. They allow the grilling of essentially rotationally symmetrical grilled food, for example sausages, cevapcici, etc., without the necessity of having to turn it by hand on a regular basis.

The problem with such grills is the dripping down fat, which decomposes on contact with the underlying hot grill element and its decomposition products are not only harmful to health, but also smell unpleasant, which is undesirable especially when used as a table grill.

It is therefore the object of the present invention to provide a grill device that catches and drains down dripping grease while avoiding contact between the grease and hot surfaces, particularly the heating elements.

According to the invention this is achieved in that in a grill device with rotatable grilling rollers under the grill rollers a collecting trough is arranged, are provided in the heat passage openings, which are provided under the grill rollers. The invention is based, in part, on the recognition that the dripping of grease in such rotary grills, unlike conventional grills without a rotating mechanism, is not substantially planar over the. Area takes place on the grilled food, but preferably where the grilled food comes into contact with the Grillwalzeπ. Accordingly, a collecting trough may be provided under the grill rollers, which does not completely cover the heating element underneath, but are provided in the Hurchtzedurchlassöffnungen, so that a very efficient heating of the grill rollers and the Grillguts can take place. It may be favorable to provide the heating elements preferably under the heat passage openings, whereby the heat transport can be significantly improved. The collecting trough is preferably arranged inclined, so that the grease can be diverted to a collecting space or collecting container. The drip pan is preferably made of a material or coated with a material which is fat-repellent, so that the grease does not adhere to the surface of the drip pan, but "pearls" from it. In addition, stripping elements can be provided which are arranged in contact with the grill rollers or very close to the grilles, so that the fat can be taken up by these stripping elements and transported away. In the presence of such scraper elements, the drip pan provided substantially flat beneath the grill rollers can be dispensable. Preferably, the heat passage openings are in the form of longitudinal slots, and preferably these longitudinal slots are arranged substantially parallel to the longitudinal axis of the grill rollers and below the grill rollers. In particular, the Hitzedurchlassöffπungen should be arranged in the vertical projection surface under the Grillwalzeπ. Preferably, these passage openings transversely to the longitudinal direction of the swelling rollers have a width which is slightly smaller than the diameter of the grill rollers. In particular, the width is between about half the diameter and 95% of the diameter, and preferably between 75% and 95% of the diameter.

A raised edge may be provided around the heat passage openings. The raised rim and the Hurchtzedurchlassöfföffuπgθπ ensure that the grease can not flow to the edge of the heat passage openings and from there can drip down on the heating element. Conveniently, the topography of the sump is designed so that the fat can flow away from the heat passage openings along an inclination and is collected in flow channels in order to achieve the fastest possible flow of the grease. The drive of the grill rollers may comprise an electric motor. It can also be another drive, for example, by hand, be provided.

In an electric drive electrical connection contacts may be provided on the drive or on the frame. It can also be a power supply via a conventional connection cable or a power supply via batteries or accumulators, etc. may be provided. The grill device may further comprise a handle, the handle is preferably thermally insulated from the actual Grillvorrϊchtung. The handle is preferably connected to the frame, so that with the handle of the entire frame with the grill rollers and possibly also with the attached trough can be moved. It may be favorable to provide the drive, in particular an electric drive, in the handle. In such a constellation, it is favorable to provide the electrical connection contacts on the rahmeπseitigen end of the handle, in particular, these may be provided projecting downwardly, or be provided in female terminal contacts so that the corresponding mating contacts are brought into engagement by a downward movement can.

The grill device may further comprise a base part with a heating element. The heating element may be, for example, an electrical heating element. The power supply for the electric heating element and for an electric drive of the grill rollers can be combined. In particular, corresponding mating contacts may be provided in the base part to the electrical connection contacts. The electrical connection contacts and the mating contacts can be designed such that they are provided as a detachable connection device for the frame or the collecting trough on the base part. This allows a very simple, yet stable connection between the base part and the frame and / or the drip pan. The connection device can be designed as a simple pluggable connection device, but it can also additionally have a lock. The grill device also has a collecting container connected to the collecting trough. The collecting container may be formed integrally with the collecting trough, but is preferably formed separately, which allows thermal insulation of the collecting container. The collecting container can be formed, for example, by a suitable arrangement, air ducts, heat exchanger ribs, etc., in such a way that it is cooled.

The frame, the Griilwalzen and / or the drip pan may be formed as a connectable to the base part Drβhgrilleinsatz. It may be convenient to detachably form the drip pan of the Drehgrilleϊnsatz. It may also be favorable to encapsulate the rotary grille insert in a sealed manner, for example by means of appropriate seals, so that it can be cleaned without difficulty. It can also be favorable to design the rotary grille insert in such a way that, for example, an electric drive can simply be separated therefrom in order to be able to clean the individual parts separately.

The invention further relates to a table grill, comprising a grilling device according to the invention, a Drβhgrilleinsatz for such a grill device and a Basϊsteil for a table grill or a grill device according to the present invention, wherein the base part has two hingedly connected shell halves, wherein provided in at least one shell half, the heating element is and wherein this is formed at least one shell element for receiving the rotary grille insert. The shell elements are in particular so foldable that they are arranged in the folded state substantially mirror-symmetrical to each other and are substantially closed in this state like a shell towards the outside, so that the base part can be stored as simple and relatively space-saving. In its unfolded state, the two shell halves lie essentially in one plane or are arranged at a very obtuse angle to one another and thus form a relatively large bearing surface. It can be provided in both shell halves a heating element, so that a rotary grill insert or a grill insert or a cooking insert can be provided, which covers both Schälleh halves. Preferably, however, a separate insert is provided for each shell half. It is advantageous if at least one of the shell elements is designed such that other grill or cooking inserts can be used in addition to the rotary grill insert. Thus, for example, an insert may be provided which has a substantially circular opening with a receiving edge into which a pot or a wok can be inserted. It can be provided flat grill or baking inserts, for example, for baking waffles, or to grill on a "hot stone" or in a pan food or baking. The shell elements may be designed to be foldable so that they can be provided with such a distance from each other in the folded state in which the shell elements are arranged substantially symmetrical to each other, that grilling material located therebetween can be grilled from both sides. For example, it is possible to cook a steak from both sides at the same time. It may be convenient to provide a clamping device with which the two shell halves are held in intimate contact with the food to be cooked.

The invention further relates to a grill set, comprising a base part according to one of claims 16 to 19 and one or more cooking inserts.

The invention and embodiments of the invention are explained below with reference to exemplary embodiments, for which the following applies:

Fig. 1 is an exploded view of a Griilvorrichtung according to the present invention;

Fig. 2 is a detail view of the grill device of Fig. 1;

Fig. 3 is an alternative embodiment of the rotary grill insert;

Fig. 4 is a base part in the folded state;

Fig. 5 is the base part of Figure 4 in the unfolded state.

Fig. 6 is a wok insert;

Fig. 7 shows a grill set according to the present invention.

In Fig. 1 can be seen a grill device 2, comprising a frame 5 and a plurality of mutually substantially parallel arranged in the frame 4 Grill rollers 6, which are each rotatably mounted about its longitudinal axis. It also recognizes a handle 8, in which a drive 10 is housed for rotating the grill rollers 6 about their longitudinal axes. The grill rollers 6 are rotatably suitably coupled to each other, for example, by gears which are provided on the end face 12 in engagement and connected to the grill rollers 6 are provided. The gears may be open or enclosed. The drive 10 can be designed such that it rotates in a direction or alternately in a first and then in an opposite side second direction at a certain predetermined or preselectable speed.

A drip pan 14 is arranged under the grill rollers. It essentially forms a floor for the frame 4. The sump 14 may be detachably arranged so that it can be cleaned separately. The drive 10 may include an electric motor (not shown).

As can be seen in the detail view of Fig. 2, electrical connection contacts 16 are provided which are provided in the form of pins 18 which fit into corresponding mating contacts 20. The electrical connection contacts 16 or the pins 18 and the corresponding mating contacts 20 are designed so stable that they represent a detachable connection device 27.

In Fig. 1 shows a formed from the frame 4, the rotating rollers 6 and the collecting tray 14 rotary grille insert 26 and a base member 22. The rotary grill insert 26 is shown in a position in which he is not yet connected to the frame 22 by means of the connection device 24 is. Under the rotary grill insert 26 is further seen a part of a heating element 28. The heating element 28 is a conventional electrical heating element. The power supply for the heating element may be coupled to the mating contacts, so that the power supply of the drive motor 12 via the mating contacts 20 and the electrical connection contacts 16 may be realized.

In Fig. 1 it can also be seen that the base part 22 of two shell elements 30, 32 is formed. The two shell elements 30, 32 are formed substantially mirror-symmetrically and connected by a hinge 34 hinged together. It can also be seen in particular that the shell element 32 is provided with mating contacts 20. In the embodiment of FIG. 1, the base part 22 stands on a foot 34, which has a central foot 36 and two side feet 40 connected thereto with a scissors mechanism 38. In the configuration of FIG. 1, the grill device 2 can be used as a table grill 2 become.

Fig. 3 shows an alternative embodiment of a rotary grill insert 26 in an exploded view. Again, you can see the frame 4 and the grill rollers mounted therein 6. On the frame you can see a pin 42, which has a non-circular shape and with a entspre ™. chenden recording on the drive 8 cooperates. Thus, the frame 4 with the grill rollers 6 can be relatively easily detached from the drive 8 and the collecting trough 14. The sump 14 is preferably detachably connected to the drive 8, so that drip tray 14 and frame 4 can be cleaned with the grill rollers 6, for example in the winder, so that only the handle 8 has to be cleaned by hand.

In the drip tray 14 can be seen heat passage openings 44, which are each arranged in vertical projection under the grill rollers 6 and substantially parallel to the longitudinal axis thereof. It can be seen, in particular, that the heat transfer openings are longitudinal slots which are substantially continuous over the entire length of the grill rollers. It can also be seen that a raised edge 46 is provided around the respective heat passage openings 44. This ensures that the dripping grease remains in the sump and is discharged. It can also be seen a drain opening 48, which serves to drain the grease in a (not shown) collecting container. The collecting container can be arranged separately in the base part 22, preferably removable, so that it can be relatively easily removed from the base part for emptying.

Fig. 4 shows the base part 22, comprising the two shell elements 30, 32 in the folded position. It can be seen how space-saving the base part 22 can be merged. Carrying handles 48 allow easy transport. Feet 50 allow the erection of the base 22 upright. Folding feet 52 can be folded out in the unfolded state of the base part 22, so that the foot 40 is not necessarily required

In the unfolded state of FIG. 5 it can be seen that the foot rests 50 simultaneously serve as a stop for the hinge 54, so that unintentional folding back of the two shell elements 30, 32 can not take place. In the illustration of FIG. 5, waffle-iron-like inserts 56 are provided in both shell parts 30, 32. In Fig. 6 a wok insert 58 is shown. The wok insert 58 has basically the same basic shape as the rotary grille insert 26 and the waffle insert 56, but it has a receiving openings into which a correspondingly shaped wok 60 can be inserted.

In Fig. 1, a further Grilleϊnsatz 59 is provided in the manner of a "hot stone".

The inserts 26, 56, 58, 59 and 64 are preferably formed so that they can engage in the corresponding shell element 30, 32. This applies in particular ^¬ sondere for the wok insert 58 and the insert 56 waffle provided without the electrical connection contacts sixteenth However, it can be provided on these inserts pins 18, similar to the electrical contacts 16, with which they can be connected to the same Anschlusseinrichtuπg 24 as well as the rotary grill insert 26.

Fig. 7 shows a grill set 62, comprising a base part 22, which has a different shape than the base part 22 of Figures 1 to 6. This base part 22 also has two shell elements 30, 32. Both shell elements θ are in essence mirror-symmetrical to each other and foldably connected to one another. It can be seen conventional grille inserts 64, which are provided in both shell elements 30, 32- It also recognizes a rotary grill insert 26 with a sump 14, which is slightly different than the rotary grille insert 26 of the embodiment of Figures 1 to 6. In particular there are the Grill rollers 6 substantially the same length, so that a simple structure is possible. Also, the grill set 62 shows another foot 40 as compared to the foot of FIG. 1. Grill inserts 26, 56, 58, 59, 64, and more particularly the catching drum 14, may be made of a sheet metal material. In particular, they are made of a material to which dripping grease does not readily adhere, for example, Teflon, etc., but preferably drains off. They can also be made of other materials, such as heat-resistant plastic or ceramic materials. Again, it is preferable to use material which allows a quick drainage of dripping fat.
