Description

[0001] The invention relates to a portable table grill.

[0002] Tabletop grills are used for cooking food. They are characterized by their compact dimensions, allowing them to be placed on a table, for example, in the center of a dining table, allowing people sitting around the grill to cook food, such as grilling or frying.

[0003] Such tabletop grills are sometimes portable, meaning they're not only compact but also designed for easy assembly and disassembly. This overall design allows for easy storage. This compactness is a must, especially when camping.

[0004] Various tabletop grills are known in the prior art. For example, CN 201920538 U discloses a grill whose external dimensions are designed to be placed in the center of a table. However, this design is generally perceived as relatively large. There are no plans to reduce the size of the tabletop grill for transport purposes.

[0005] Another embodiment is disclosed in WO 2019 / 206887 A1. The tabletop grill disclosed here is composed of various sheet metal parts that are assembled by a user before use and disassembled after use. This results in an assembled use position and a disassembled transport position of the tabletop grill. A disadvantage of this embodiment, however, is that the entire grill must be disassembled, which is particularly problematic after grilling due to the contamination of the individual parts. Furthermore, the parts must be stored individually in additional packaging.

[0006] Against this background, the invention aims to provide a table grill that is easy to handle and at the same time compact and easy to transport.

[0007] This object is achieved by a portable table grill having the features of claim 1 and by a portable table grill having the features of claim 2.

[0008] Advantageous embodiments arise from the dependent claims of the description.

[0009] Unless otherwise indicated, the following statements refer to both embodiments, namely those according to claim 1 and those according to claim 2.

[0010] When reference is made to “top” or “bottom” in the following explanations, these directions refer to the table grill as it is placed on a table.

[0011] The tabletop grill has a tray. The tray is formed by a base and attached walls. A heat source, such as an insert for holding charcoal or a burner for burning liquid or gaseous fuels, usually a gas burner, is arranged in the tray, i.e. in the space enclosed by the base and walls. The tray is preferably dimensionally stable. It can preferably be formed as a single-piece deep-drawn part or cast part, so that the walls of the tray are molded to the base. The tray is preferably a cast part, as the cast material stores the heat emitted by the heat source and thus has a more even effect on the overall heat emission of the grill onto the food being cooked.

[0012] The tub is open at the top so that a grill rack can be placed above it, on which the food to be cooked is placed, and the heat emitted by the heat source reaches this grill rack.

[0013] To collect dripping liquids from the food which is cooked above the heat source, for example on a grill rack or a pot rack, a usually removable grease tray can be provided in the bottom area of ​​the tray.

[0014] The tabletop grill also features a windshield attachment made of a metal material; this, too, is preferably dimensionally stable. The windshield attachment preferably encloses the space it encloses circumferentially, i.e., on all four sides. It is thus ring-shaped. The windshield attachment is designed to be detachable from the pan, in particular, without the need for tools.

[0015] When in use, the tabletop grill rests on the upward-facing edge of the tray. The space enclosed by the tray is extended upwards by the windshield attachment, thus increasing the depth of the combustion chamber.

[0016] It can be provided that an upper cooking level defined by a grill rack or pot rack, on which food or cookware can be placed and heated with the heat source during operation, is located above the upper end of the tub. In this case, the tabletop grill can also be used to heat cookware, such as a pot, on the cooking level whose diameter is larger than that of the tub. If this is provided, it is preferably provided that the wind protection attachment extends above this level and thus encloses the heat source when the wind protection attachment is in use, so that the heat source is protected even in strong winds.

[0017] To securely hold the windshield attachment on the tub, the front section of the windshield attachment facing the tub has a connecting feature. The connecting feature can be a correspondingly provided front surface or a receptacle. The tub can also provide structures to complete the connecting feature. The connecting feature is preferably characterized by the fact that it causes the windshield attachment and tub to interlock, so that the windshield attachment on the tub is not only supported vertically but also secured against horizontal displacement.

[0018] The frontal area of ​​the wind protection attachment which has the connecting feature is the end section of the wind protection attachment which points towards the tub, approximately the last 20%, preferably 10% of the height of the wind protection attachment.

[0019] To place the tabletop grill into transport position, the windshield attachment is removed from the top edge of the tray, turned upside down, and inserted into the tray so that it is essentially contained within the tray, or held against the tray while enclosing the tray. In the first alternative, the tray thus provides a storage space for the windshield attachment.

[0020] In the first embodiment (see claim 1), the remaining area of ​​the wind protection attachment, with its radially outward-facing contour, is smaller than the radially inward-facing contour of the tub wall. If the wind protection attachment is to be moved from a use position of the table grill to a transport position, it is removed from the upper edge of the tub, then rotated about a horizontal axis so that it is oriented upside down, and then inserted into the tub in this inverted position. This means that the end face which, in the use position of the table grill, faces towards the tub, i.e. downwards, now points away from the tub, i.e. upwards, and the end face which, in the use position, faces upwards, now points towards the tub, i.e. downwards. The connecting mechanism on the wind protection attachment side usually protrudes from the tub.However, since this is only located in the end area of ​​the windscreen attachment, it represents only a small overhang; overall, the height of the table grill is significantly reduced in the transport position compared to the use position with the windscreen attachment attached to the tub.

[0021] In the second embodiment (see claim 2), it can be provided that the windshield attachment, in its radially inward-facing contour, is larger than the radially outward-facing contour of the tub wall. Moving the windshield attachment from the use position to the transport position is carried out analogously to that described above. In contrast to the first embodiment, in this second embodiment, the windshield attachment encloses the tub on the outside in the transport position. The advantage of the reduced height of the table grill in its transport position is also achieved in this way.

[0022] The storage volume provided by the tray can also be used to accommodate and transport other parts necessary for operating the table grill, such as a gas cartridge, pot rods, etc. This allows for an extremely compact transport position in which the parts stored in the tray are protected.

[0023] Preferably, the windshield attachment is supported on the upper edge of the tray via the connecting mechanism when the tabletop grill is in the transport position. This ensures that the windshield attachment is securely held relative to the tray in the transport position.

[0024] In the event that the wind protection attachment is inserted into the tub in the transport position, the wind protection attachment does not rest, or does not rest significantly, on the floor of the tub or on a grease drip tray arranged above the floor of the tub and designed as a separate intermediate floor, so that the wind protection attachment, in particular the edge of the wind protection attachment pointing upwards in the use position, does not become dirty when the wind protection attachment is placed in the transport position after use of the table grill.

[0025] In order to effectively direct the heat emitted by the heat source onto the food being cooked, the draft shield attachment is designed to make continuous contact with the wall of the tub when in use, along their respective, facing edges. The wall of the tub is seamlessly extended upwards by the draft shield attachment. This prevents cold air from outside from being drawn into the area enclosed by the draft shield attachment and the tub, and prevents hot air from escaping from the space enclosed by the draft shield attachment and the tub at the transition between the tub and the draft shield attachment. The fact that the tub and the draft shield attachment lie on top of each other creates a certain degree of sealing. This sealing can be improved by designing the connection, for example with an edge or a labyrinth.

[0026] To configure the connection mechanism, it is preferably provided that the wind protection attachment has a flange facing the edge of the tub wall in the use position. This flange is spaced from the front end of the wind protection attachment, which points downwards in the use position, such that this end, together with the flange, provides an edge-guided mounting receptacle, thus approximately 4 mm to 20 mm. The wind protection attachment rests with its flange on the front side of the tub; with its projecting front end, it projects into the interior of the tub or surrounds the wall on the outside.

[0027] It is preferably provided that a grill grate is attached to the windbreak attachment. This makes the windbreak attachment an integral part of the table-top grill. By attaching the grill grate to the windbreak attachment - and not in the tub - the distance between the grill grate and the heat source can be increased so that the heat can be evened out below the grill grate. It is preferably provided that for this purpose the windbreak attachment has at least one, usually several, approximately three or four support surfaces projecting inwards from the rest of the windbreak attachment, for example in the form of support lugs, for supporting a grill grate placed on top in the use position. The at least one support surface usually projects into the space enclosed by the windbreak attachment.If several support surfaces are provided, it is preferably provided that the support surfaces provide a support surface on which a grill grate can be placed.

[0028] Preferably, the grill grate is slightly recessed, approximately 5 mm to 10 mm, from the edge of the windbreak attachment, which faces upwards in the use position, to form a threshold. The edge of the windbreak attachment, which protrudes above the grill grate and forms the threshold, serves to prevent food placed on the grill grate from rolling or sliding down. Furthermore, it is preferably provided that the grill chamber is essentially free in the radial direction and not enclosed by the windbreak attachment.

[0029] In a further embodiment, the wind protection attachment can be provided with at least one inwardly projecting support lug, which can also be designed as a support surface, for supporting the grill grate even in the transport position. These are preferably constructed analogously to the support surfaces described above with regard to supporting the grill grate in the use position. This holds the grill grate in the transport position at the top, so that the tray is closed at the top in the transport position. This allows parts located in the tray to be transported safely.

[0030] However, in contrast to the support surfaces for supporting the grill grate in the use position, it is preferred that the grill grate in the transport position be flush with the upper edge of the windshield attachment in the transport position or protrude slightly above it. This maximizes the volume in the tub below the grill grate. In this case, the distance between the upper edge of the windshield attachment in the use position and the support surfaces is greater than the distance between the upper edge of the windshield attachment in the transport position and the respective support surfaces.

[0031] If the grill grate extends beyond the upper end of the windscreen attachment in the transport position, additional means can be provided to press the grill grate onto the corresponding support surfaces. This means can be a strap attached to the tray and guided over the grill grate. However, it is preferred to provide a lid covering the grill grate at the top, preferably designed as a cutting board. This lid can be attached to the tray with a strap or other fastener.

[0032] If the windbreak attachment has support surfaces for supporting the grill grate in the transport position and in the use position, it is preferably provided that these are vertically aligned. In this case, these support surfaces can be designed as ribs that protrude inward from the windbreak attachment and are usually oriented vertically. The support surfaces are then formed by the vertically facing end faces of the ribs. The provision of ribs increases the stability of the support surfaces and the windbreak attachment, ensuring that the grill grate is held securely on the support surfaces.

[0033] In a preferred embodiment, the heat source is a burner, in particular a gas burner. In this case, the wall of the tub is typically provided with an opening through which a burner tube leading to the burner is guided in the use position. The burner tube can also be designed as a hose.

[0034] To prevent the tabletop grill from being used improperly in its transport position, the windshield attachment is designed to close this opening when in the transport position. To achieve this, the windshield attachment covers the opening when inserted into the tray or when enclosing the tray wall.

[0035] Preferably, the heat source is a circular burner, particularly a gas-powered one, as is commonly used on cooking stoves. A circular burner is characterized by its typically circular shape with annularly arranged fuel outlet holes, resulting in a circular flame pattern.

[0036] Even though such a circular burner is excellent for heating cookware, such as pots or pans, it emits heat in a locally concentrated, almost pinpoint manner—unlike a rod burner, for example. However, this is problematic for grilling on a grill grate extending over a specific area due to the lack of heat conduction. To counteract this, the windshield attachment and, preferably, the pan can be manufactured as cast parts. Cast parts store heat energy and thus even out the temperature distribution on a grill grate positioned above the heat source.

[0037] The invention is explained in more detail with reference to the accompanying figures. They show: Fig. 1: An insight into the portable table grill in a first use position, Fig. 2: the portable table grill in a second use position, Fig. 3: the portable table grill in a third use position, Fig. 4: the portable table grill in the third use position in a sectional view, Fig. 4a: a detailed view of the Fig. 4 part of the table grill shown below right, Fig. 5: the portable table grill in its transport position as a view into the device, Fig. 6: the portable table grill in its transport position with the grill grate attached, Fig. 7: the portable table grill in its final transport position, Fig. 8: the Fig. 1 shows the table grill shown in its third use position in a grill configuration, but with the grill grate and windscreen hidden, thus depicted in its first use position, but with a diffuser plate mounted on the pot rod, Fig. 9: the Fig. 8 shown configuration, but additionally with attached wind protection attachment, thus according to the type of second use position and Fig. 10: The pan of the table grill in a view with the burner inserted and the grease tray removed.

[0038] Fig. 1 shows an overview of the portable table grill 1. The portable table grill 1 comprises a dimensionally stable, one-piece tub 2 manufactured as a cast part with a base 3 and side walls 4 formed thereon.

[0039] A heat source 5, here designed as a circular burner, is provided in the tank 2. The circular burner 5 is inserted into a burner mount 7 on a burner dome 6. The burner is supplied with fuel gas via a burner tube 8 using a fuel gas cartridge (not shown here); the Venturi nozzle 9 required to form the fuel gas mixture is arranged outside the tank 2 on the burner tube 8.

[0040] In the Fig. In the first use position of the table grill 1 shown in Figure 1, a pot rack 10 is provided above the heat source 5, on which a cooking utensil can be placed and heated by the heat source 5. A grease drip tray 11 is inserted at the bottom of the pan 2, which collects liquids dripping from the cooking level above the heat source 5, such as fat from food to be grilled or water boiling over from a cooking utensil.

[0041] Fig. Figure 2 shows a second use position of the table grill 1. A dimensionally stable windshield attachment 12, also designed as a cast part, is placed on the pan 2, or rather on its wall 4. This windshield attachment 12 is ring-shaped and its shape is adapted to the shape of the pan 2, or rather to the arrangement of the walls 4 of the pan 2, so that the space enclosed by the pan 2 is enlarged upwards by the windshield attachment 12. The cooking level provided by the upper end of the pan rod 10 is enclosed by the windshield attachment 12.

[0042] The wind protection attachment 12 has a circumferential flange 13 in its front area 15 facing the tub 2, which projects outwards from the wind protection attachment 12. As shown in Fig. 4, the wind protection attachment 12 rests with the flange 13 on the upper edge 14 of the wall 4 of the tub 2. Furthermore, the wind protection attachment 12 projects into the tub 2 with its front end 15 facing the tub 2 and contacts the wall 4 of the tub 2 on the inside. The front end 15 and the flange 13 thus form an edge-guided mounting receptacle on the wind protection attachment side, by which the wind protection attachment 12 is securely held on the tub 2 both horizontally and vertically.

[0043] A third usage position is in Fig. 3; a sectional view of the Fig. 3 represents Fig. 4. A grill grate 16 is placed on the wind protection attachment 12 placed on the tub 2. The grill grate 16 is supported on support surfaces 17 designed as vertical ribs 23, which are Fig. 2 and Fig. 4, and is thus supported on the wind protection attachment 12. In this position of use, the grill grate 16 is slightly recessed from the upper edge 18 of the wind protection attachment 12 into the space enclosed by the wind protection attachment 12, so that a threshold 19 is provided by the upwardly facing end of the wind protection attachment 12. In Fig. 3 shows a lid 20 used here as a tray, which in this position of use has no significant function with respect to the table grill 1 (see below).

[0044] By securing the grill grate 16 to the windshield attachment 12, the distance between the heat source 5 and the grill grate 16 is significantly increased compared to an arrangement in which the grill grate 16 would be held on the upward-facing edge of the pan 2; at the same time, its secure mounting is ensured. Furthermore, the grill grate 16's external shape fits into the windshield attachment 12, so that the combustion chamber enclosed by the pan 2 and the windshield attachment 12 is essentially completely covered by the grill grate 16.

[0045] For transporting the table grill 1, it is provided that it is placed in a transport position. This transport position of the table grill 1 is shown in the Fig. 5 to 7.

[0046] Fig. 5 shows a view into the tub 2 of the table-top grill 1 in its transport position: The wind protection attachment 12 has been removed from the upper edge 14 of the wall 4 of the tub 2 and rotated about a horizontal axis, so that the edge 18 pointing upwards in the use position now points downwards and the connecting mechanism pointing towards the tub 2 in the use position, comprising the circumferential flange 13 and the front end 15 of the wind protection attachment 12, here in particular the corresponding front end 15, points upwards in the transport position. The outwardly projecting flange 13 of the wind protection attachment 12 now rests with its other side on the upper edge 14 of the wall 4 of the tub 2. The wind protection attachment 12 is thus essentially received by the tub 2 and inserted into it.The height of the table grill 1 in the transport position is thus compact despite the wind protection attachment 12 being usable in a use position and stowed in the table grill 1 in the transport position.

[0047] To operate the table grill 1 in the Fig. 5, the opening 21 in the wall 4, which is necessary for the user-side installation of the burner 5 and through which the burner tube 8 is passed in the position of use, is closed by the wind protection attachment 12.

[0048] The wind protection attachment 12 also has, when oriented in the transport position, upwardly facing support surfaces 22, or rather the end faces of the ribs 23 opposite the support surfaces 17, onto which the grill grate 16 is placed in the transport position, thus closing off the volume enclosed by the tray 2 at the top. The additional utensils necessary for operating the tabletop grill 1, such as the pot rod 10 and the burner 5, as well as the gas cartridge (not shown in the figures), can be placed into the volume, thus providing an overall self-contained box inside which the components can be safely transported.

[0049] As in Fig. 6, in the transport position of the table grill 1, the upwardly facing end of the grill grate 16 protrudes slightly, approximately by a few millimeters, over the upwardly facing edge 15 of the wind protection attachment 12. The support surfaces 22 pointing upwards in the transport position are positioned accordingly, that is: the support surfaces 22 pointing upwards in the transport position are closer to the edge 15 of the wind protection attachment 12 pointing upwards in the transport position than the support surfaces 17 pointing upwards in the use position are to the edge pointing upwards in the use position, as shown in Fig. 4 can be recognized.

[0050] To close the top of the table grill 1 in the transport position, the lid 20, which can also be used as a cutting board in this position, is placed on top and clamped with an elastic belt 24 to the tub 2, or to anchoring lugs 25 pointing downwards in the lower area, arranged opposite to the bottom 3 of the tub 2 and essentially aligned with the respective wall 4, so that the grill grate 16 is pressed onto the support surfaces 22 (see Fig. 7). It should be noted that the cover 20 is positioned in a different direction than shown in Fig. 3 is rotated about a horizontal axis so that the side walls of the tray forming the lid 20 enclose the upper end of the table grill 1. This prevents the grill grate from rattling during transport.

[0051] The heat source 5, designed as a circular burner in the exemplary embodiment, emits the heat in a locally focused manner, so that a pot (not shown in the figures) can be heated on the pot rod 10 in the cooking level provided by the upper end of the pot rod 10, without the flames of the heat source 5 spreading over the edge of the cookware and causing soot to form there. This focused heat emission is, however, disadvantageous for operation in the grill configuration, i.e. with the grill grate 16 attached on top, since the significantly lower heat conduction of the grill grate 16 compared to a cookware base means that the heat distribution cannot be homogenized. As a result, the grill grate 16 can essentially only be used effectively above the heat source 5.

[0052] To counteract this, a diffuser plate 30 made of steel, in particular stainless steel, is provided above the heat source 5 below the grill grate 16. The diffuser plate 30 is arranged between the heat source 5 and the closed area 31 of the grill grate 16, i.e., the area of ​​the grill grate 16 in which the space between two adjacent grate bars is closed. The diffuser plate 30 projects over the heat source 5, which is designed as a circular burner; the grill grate 16, in turn, projects over the diffuser plate 30, both in a top view.

[0053] The heat emitted by heat source 5—here: the flame and the hot exhaust gases from the circular burner—heats diffuser plate 30. Through heat conduction within diffuser plate 30, the heat is distributed throughout the plate; at the same time, diffuser plate 30 itself becomes a heat radiator. The heat radiation emitted by diffuser plate 30 is passed from this distributed area to the closed area 31 of grill grate 16, where it can be further distributed via heat conduction through the direct connection of the adjacent grate bars. This already improves heat distribution across grill grate 16.

[0054] In addition, the hot exhaust gases are guided to the outside through the diffuser plate 30, as in particular in Fig. 8: The diffuser plate 30 is roof-shaped; it has a uniaxial ridge 32. The grilling surface provided by the grill grate 16 is rectangular (not square). The direction of the ridge 32 points in the direction of the longer semi-axis of the grilling surface provided by the grill grate 16. The hot exhaust gases emitted by the heat source 5 are collected under the roof-shaped diffuser plate 30 in the area of ​​the ridge 32 and from there are directed to the radially outer areas of the grilling surface provided by the grill grate 16. There they encounter the closed area 31 of the grill grate 16 and further heat the grill grate 16 in this area. This maximizes the efficiency, namely the utilization of the energy emitted by the heat source 5.

[0055] In order to prevent a heat imprint from being created on the grill grate 16 in alignment with the outer edge 33 of the diffuser plate 30 as a result of the hot exhaust gases emitted by the heat source 5 being directed to the outer edge 33 of the diffuser plate 30 and then flowing vertically upwards in a concentrated manner, it is provided to introduce one or more openings 34 into the diffuser plate 30. These are particularly suitable in Fig. 9. The openings 34 are arranged outside the area of ​​the diffuser plate 30, which in a plan view is aligned with the heat source 5 designed as a circular burner, including in the area of ​​the ridge 32 of the diffuser plate 30.

[0056] The diffuser plate 30 is, as in Fig. 8, the diffuser plate 30 is supported on the pot rod 10 by feet 35, here four, which are bent from the diffuser plate 30, so that the diffuser plate 30 is placed on the pot rod 10. As a result, the diffuser plate 30 rests on the pot rod 10 only with the end face of the feet 35, so that the heat introduced into the diffuser plate by the heat source 5 does not flow into the pot rod 10; thermal separation is provided by the small contact cross-section between the foot 35 and the pot rod 10.

[0057] To ensure that the diffuser plate 30 is securely held on the pan support 10, the feet 35 have recesses 36 corresponding to the width of the pan support 10, so that the feet 35 laterally enclose the pan support 10. Furthermore, the pan support 10 itself has lugs 37 pointing radially outwards relative to its provided cooking level (in Fig. 1). The lugs 37 are formed by the pot rod 10 being recessed in its upwardly directed contour, which provides the cooking surface; the resulting notch is in Fig. 1 with reference numeral 38. This provides a nose-side stop surface, preventing the feet 35 of the diffuser plate 30 from slipping off the pot rod 10.

[0058] The pot rod 10 is in this case constructed in two parts and comprises two brackets 39, 40. The two brackets 39, 40 are identically constructed. Since the brackets 39, 40 can be removed from the tub 2 in order to transfer the table grill 1 into its transport position, the brackets 39, 40 are held in receptacles 41 on the bottom 3 of the tub 2 in the area of ​​the burner dome 6. These receptacles 41 are particularly Fig. 10, in which the grease drip tray 11 and the pot rod 10 are dismantled.

[0059] The receptacles 41 for receiving the end sections of the brackets 39, 40 of the pot rod 10 have an oval contour. The long axis of the contour points radially relative to the heat source 5. The end sections of the brackets 39, 40 are designed accordingly, i.e., they have corresponding oval contours arranged at a 90° angle to each other.

[0060] This ensures that the brackets 39, 40 are positioned as shown in Fig. 1 provide a pot cross overall and not an outwardly framed receptacle (not shown in the figures).

[0061] During operation of the tabletop grill 1, the air surrounding the heat source 5 rises due to its heating. This creates a local negative pressure in the area below the heat source 5, or rather in the area of ​​the burner dome 6. At the same time, it is precisely the burner dome 6 that is particularly heated by the heat source 5. The burner dome 6 also releases this heat downwards, so that the base (not shown in the figures) on which the tabletop grill 1 stands also heats up.

[0062] To counteract this, it is intended that in the area of ​​the transition 50 between the floor 3 and the wall 4 to which the longer semi-axis of the tub 2 points (in Fig. 4 and Fig. 4a, the wall shown on the right), a nozzle-like opening 51 is introduced. This nozzle-like opening 51 leads into the interior of the pan 2, namely into an intermediate space 52, which is enclosed as an air-filled thermal insulation barrier between the floor 3 of the pan 2 and the grease collecting pan 11; the grease collecting pan 11 represents an intermediate floor. Through the nozzle-like opening 51, the air is accelerated from the wall 4 towards the heat source 5, or rather the burner dome 6. In the area of ​​the heat source 5, or rather around the burner dome 6, as shown in the Fig. 1 and Fig. 5, the grease collection tray 11 has a large opening spanning the burner dome 6, through which the air from the heat source 5 is drawn in from the intermediate space 52. The cold air accelerated through the nozzle-like opening 51 toward the heat source 5 or burner dome 6 flows around the burner dome 6 and cools it. The bottom 3 of the tray 2 is also cooled on the way from the nozzle-like opening 51 to the burner dome 6.

[0063] In Fig. 4 it can be seen that the nozzle-like opening 51 in the direction of the trough 2 widens in a funnel shape in its upper region with respect to the flow direction in order to reduce turbulence.

[0064] Because the air is accelerated from the nozzle-like opening 51 towards the burner dome 6, it reaches the burner dome 6 while still cool and is not heated in the intermediate space 52 by the heat radiated from the heat source 5 onto the grease collecting tray 11 due to a slow flow velocity.

[0065] Attached to the wall 4, to which the longer semi-axis points, or in the area of ​​the transition 50 from the floor 3 to this wall 4, is a base 53 supporting the tub 2 for placing the table grill 1 on a base. The base 53 is designed as a foot shell that surrounds the tub 2 in sections, namely on the underside, as shown in the Fig. 4 and Fig. 4a can be seen.

[0066] In Fig. 1 shows that an air gap 54 is provided between the upper edge of the foot part 53 and the tub 2. This air gap 54 is part of the Fig.4 or 4a: Ambient air is drawn in through this; it opens into a relaxation chamber 55. The relaxation chamber 55 is enclosed by the foot part 53 and the tub 2. From this relaxation chamber 55, the air is further directed through the nozzle-like openings 51 into the tub 2. The relaxation chamber 55 also serves as a deposition chamber for foreign bodies introduced through the air gap 54, thus preventing the foreign bodies from entering the interior of the tub 2 through the nozzle-like openings 51.

[0067] The air gap 54 is arranged offset above the nozzle-like openings 51, which further results in foreign bodies drawn in with the air flow being collected in the expansion space 55.
