Description

Die vorliegende Erfindung betrifft eine Gargutträgeraufnahme mit einem Rahmenelement, einem Führungselement und einem Abstandshalter zum Beabstanden des Rahmenelements zur Seitenwand. Des Weiteren betrifft die Erfindung ein Gargerät zur Aufnahme solch einer Gargutaufnahme.The present invention relates to a food support receptacle with a frame element, a guide element and a spacer for spacing the frame element from the side wall. Furthermore, the invention relates to a cooking appliance for receiving such a food receptacle.

Um sicherzustellen, dass die im Garraum herrschenden hohen Temperaturen nicht über die Gargutträgeraufnahme an das Email der Garraumseitenwände übertragen wird, muss sichergestellt sein, dass die Gargutträgeraufnahmen zur Garraumseitenwand ausreichend beabstandet sind. Die zur Beabstandung der Gargutträgeraufnahme bekannten Lösungen werden wie folgt beschrieben und in Figur 2 dargestellt. Demnach sind aus dem Dokument DE 102008041525 A1 Abstandshalter bekannt, die mittels einer Wölbung aus dem senkrechten Rahmenelement gebildet sind.In order to ensure that the high temperatures prevailing in the cooking chamber are not transferred to the enamel of the cooking chamber side walls via the food support receptacle, it must be ensured that the food support receptacles are sufficiently spaced from the cooking chamber side wall. The known solutions for spacing the food support receptacle are described as follows and in figure 2 shown. Accordingly, from the document DE 102008041525 A1 Spacers are known, which are formed by means of a curvature of the vertical frame member.

Aus dem Dokument US 3 706 302 A ist zudem eine Gargutträgeraufnahme bekannt, diese zeigt ein Führungselement, ein Rahmenelement zum Verbinden des Führungselements mit einer Garraumseitenwand und einen Abstandshalter zum Beabstanden des Rahmenelements zur Garraumseitenwand. Hierbei wird der notwendige Abstand zwischen Gargutträgeraufnahme und Garraumseitenwand durch eine Biegeumfang des Rahmenelements erzeugt.From the document U.S. 3,706,302 A a food support receptacle is also known, which shows a guide element, a frame element for connecting the guide element to a cooking chamber side wall and a spacer for spacing the frame element from the cooking chamber side wall. In this case, the necessary distance between the food support receptacle and the side wall of the cooking chamber is generated by a bending circumference of the frame element.

Aus dem Dokument DE 35 05 807 A1 ist eine Gargutträgeraufnahme bekannt, diese zeigt Führungselemente, ein Rahmenelement zum Verbinden der Führungselemente mit einer Garraumseitenwand und einen Abstandshalter zum Beabstanden des Rahmenelements zur Garraumseitenwand. Hierbei sind die Rasthaken, welche den Abstandshalter bilden, haarnadelförmig gebogenen.From the document DE 35 05 807 A1 a food support receptacle is known, this shows guide elements, a frame element for connecting the guide elements to a cooking chamber side wall and a spacer for spacing the frame element from the cooking chamber side wall. Here, the latching hooks, which form the spacer, are bent like a hairpin.

Nachteilig an diesen Lösungen ist, dass diese Wölbungen nur in Bereichen des senkrechten Rahmenelements angebracht sein können, die frei von Führungselementen sind.A disadvantage of these solutions is that these bulges can only be attached in areas of the vertical frame element that are free of guide elements.

Zudem sind aus dem Dokument DE 10240627 A1 Abstandshalter bekannt, welche aus den Führungselementen gebildet sind. Dabei stehen die Enden der Führungselemente in Richtung Seitenwand über die Rahmenelemente der Gargutträgeraufnahme hinaus und bilden somit eine Verlängerung, welche den Abstand definiert. Nachteilig an diesen Drahtüberständen ist, dass sie beim Transport aufgrund wirkender Erschütterungen zu Kratzern und Emailabplatzern, insbesondere im Sichtbereich führen.
Dokument DE 102 40 627 A1 beschreibt eine Trägervorrichtung mit einem Trägermittel 3 und wenigstens einem ersten, an einer Wandung befestigbaren Aufnahmemittel für ein Trägerteil des Trägermittels. Dabei weist das Trägermittel Verbindungsstangen mit Ausformungen auf, wobei offen bleibt, wie diese hergestellt sind.In addition, from the document DE 10240627 A1 Spacers known, which are formed from the guide elements. The ends of the guide elements protrude in the direction of the side wall beyond the frame elements of the food support receptacle and thus form an extension which defines the distance. The disadvantage of these wire overhangs is that they lead to scratches and chipping of the enamel during transport due to the impact of vibrations, especially in the visible area.
document DE 102 40 627 A1 describes a carrier device with a carrier means 3 and at least one first receiving means, which can be fastened to a wall, for a carrier part of the carrier means. In this case, the carrier means has connecting rods with formations, it being left open how these are produced.

Es ist deshalb Aufgabe der Erfindung, eine Gargutträgeraufnahme der genannten Art bereitzustellen, deren Abstandshalter die Gargutträgeraufnahme zur Seitenwand besonders präzise und gleichzeitig materialschonend beabstandet.It is therefore the object of the invention to provide a food support receptacle of the type mentioned, the spacers of which space the food support receptacle from the side wall particularly precisely and at the same time in a way that is gentle on the material.

Erfindungsgemäß wird die Aufgabe jeweils durch die Gesamtheit der Merkmale der unabhängigen Ansprüche gebildet. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben. Die Erfindung findet zudem Anwendung in einem Gargerät nach Anspruch 10.According to the invention, the object is formed by the totality of the features of the independent claims. Further advantageous configurations of the invention are described in the dependent claims. The invention is also used in a cooking appliance according to claim 10.

Die Gargutträgeraufnahme weist zumindest ein Führungselement zur Aufnahme eines Gargutträgers, zumindest ein Rahmenelement zur Aufnahme des zumindest einen Führungselements und zumindest einen Abstandshalter zum Beabstanden des Rahmenelements zur Seitenwand auf. Dabei ist der Abstandshalter durch mindestens eine Ausprägung aus dem Rahmenelement gebildet. Solch eine Ausprägung benötigt kein zusätzliches Material sowie nur einfache Verarbeitungsschritte. Die Ausprägung ist unabhängig vom Vorhandensein der Führungselemente am Rahmenelement anzuordnen ohne dabei die Funktion der Führungselemente negativ zu beeinflussen. Der Abstandshalter ist durch eine materialverdrängende Prägung aus dem Rahmenelement geformt. Dabei wird der vorzugsweise runde Stab durch Bearbeitungsstempel derart beaufschlagt, dass sich die Ausbreitung bildet. Um das Fließverhalten positiv zu beeinflussen und gleichzeitig die Stabilität des Rahmenelements aufrecht zu erhalten, greift die Prägung außerhalb der Mitte und somit nicht den gesamten Durchmesser an. Die Ausprägung wird durch zwei sich gleichmäßig zueinander bewegende Bearbeitungsstempel erzeugt. Das verdrängte Material fließt dabei vom Mittelpunkt des Querschnitts des Rahmenelements gesehen, in Richtung zugeordneter Seitenwand.The food support receptacle has at least one guide element for receiving a food support, at least one frame element for receiving the at least one guide element and at least one spacer for spacing the frame element from the side wall. In this case, the spacer is formed by at least one embossing of the frame element. Such an expression requires no additional material and only simple processing steps. The expression is to be arranged independently of the presence of the guide elements on the frame element without negatively influencing the function of the guide elements. The spacer is formed from the frame element by a material-displacing embossing. In this case, the preferably round bar is acted upon by processing stamps in such a way that the spread is formed. In order to have a positive influence on the flow behavior and at the same time maintain the stability of the frame element, the embossing takes place outside the center and therefore not over the entire diameter. The embossing is created by two processing stamps moving evenly towards each other. Viewed from the center point of the cross section of the frame element, the displaced material flows in the direction of the associated side wall.

Vorzugsweise ist die Prägung der Garraumseitenwand zugewandt. Dadurch ist sichergestellt, dass die Prägung das Rahmenelement und somit die gesamte Gargutträgeraufnahme ausreichend beabstandet. Dabei bildet die Ausprägung eine Distanz bzw. Abstandshalter. Eine besonders gute Optik wird erzielt, wenn sich die Prägung rein auf einer Seite des Rahmenelements befindet, so dass der maximale Querschnitt des Rahmenelements erhalten bleibt. Rein optisch verschwindet die Prägung für den Nutzer des Gargeräts, wenn sich die Prägung ausschließlich auf der der Garraumseitenwand zugewandten Querschnittshälfte des Rahmenelements befindet.The embossing preferably faces the side wall of the cooking chamber. This ensures that the embossing of the frame element and thus the entire Food carrier receptacle sufficiently spaced. The expression forms a distance or spacer. A particularly good look is achieved when the embossing is located purely on one side of the frame element, so that the maximum cross section of the frame element is retained. From a purely visual point of view, the embossing disappears for the user of the cooking appliance if the embossing is located exclusively on that half of the cross-section of the frame element which faces the side wall of the cooking chamber.

Vorzugsweise weist die Prägung zur Beabstandung der Gargutträgeraufnahme eine Höhe H auf. Die Höhe H und somit der Abstand des Rahmenelements zur Garraumseitenwand bestimmt die Dämmung des Rahmenelements bezüglich der heißen Garraumseitenwand. Aufgrund der dämmenden und schlechten Wärmeleiteigenschaft der Luft zwischen Rahmenelement sowie der verlängerten Kriechstrecke, die die Wärme durch die Prägung nehmen muss, ist die Seitenwand und das Email umso kühler je höher der Abstand ist. Die Höhe H wird dabei so gewählt, dass die Dämmeigenschaft der Prägung ausreichend ist und gleichzeitig der ästhetische Designeindruck - aufgrund eines zu hohen Abstandes - nicht beeinträchtigt wird. Da die Höhe H und somit die Beabstandung des Rahmenelements zur Garraumseitenwand negative Einflüsse auf die mögliche Breite des Gargutträgers im Garraum hat, wird versucht, die Höhe H der Prägung möglichst gering auszulegen. Demnach beträgt die Höhe h zwischen 0,5 mm und 5 mm, vorzugsweise 1 mm bis 3 mm und insbesondere 2 mm.The embossing preferably has a height H for spacing the food support receptacle. The height H and thus the distance between the frame element and the cooking chamber side wall determines the insulation of the frame element with respect to the hot cooking chamber side wall. Due to the insulating and poor thermal conductivity of the air between the frame element and the extended creepage distance that the heat has to take through the embossing, the side wall and the enamel are the cooler the greater the distance. The height H is selected in such a way that the insulating property of the embossing is sufficient and at the same time the aesthetic design impression—due to too great a distance—is not impaired. Since the height H and thus the spacing of the frame element from the side wall of the cooking space has a negative impact on the possible width of the food support in the cooking space, an attempt is made to keep the height H of the embossing as small as possible. Accordingly, the height h is between 0.5 mm and 5 mm, preferably 1 mm to 3 mm and in particular 2 mm.

Durch vorzugsweise runde Stempel wird eine vorzugsweise symmetrische Prägung erzeugt. Solche symmetrischen Prägungen erzeugen besonders wenig Kanten die die Garraumseitenwand beschädigen, z. B. verkratzen können. Alternativ ist die Prägung assymetrisch gestaltet, um Sonderlösungen, z. B. unebene oder schräg verlaufende Garraumseitenwände, zu realisieren. Zudem entstehen besonders gute Abstandshalter, wenn die Prägung symmetrisch bezüglich einer horizontalen Achse verläuft.A preferably symmetrical embossing is produced by preferably round dies. Such symmetrical embossings produce particularly few edges that damage the side wall of the cooking space, e.g. B. can scratch. Alternatively, the embossing is designed asymmetrically to accommodate special solutions, e.g. B. to realize uneven or sloping side walls of the cooking space. In addition, particularly good spacers are created when the embossing runs symmetrically with respect to a horizontal axis.

Vorzugsweise ist das Rahmenelement aus Draht gebildet. Dieses Drahtmaterial mit seinem Querschnitt, z. B. rund, quadratisch, rechteckig, oval oder vieleckig, ist besonders einfach zu bearbeiten, zu schweißen und zudem kostenneutral. Dabei ist das Material des Rahmenelements auf die benötigten Fließeigenschaften angepasst, insbesondere C9D, 1.4301, 1.4597. Zudem ist eine Beschichtung, insbesondere mit Crom oder Plasma vorgesehen.Preferably, the frame member is formed from wire. This wire material with its cross section, z. B. round, square, rectangular, oval or polygonal, is particularly easy to process, to weld and also cost-neutral. The material of the frame element is adapted to the required flow properties, in particular C9D, 1.4301, 1.4597. A coating, in particular with chrome or plasma, is also provided.

Vorzugsweise ist das Rahmenelement aus wenigstens einem senkrechten Drahtelement, insbesondere aus zwei im Wesentlichen parallel zueinander angeordneten Drahtelementen gebildet. Dies ermöglicht eine besonders einfache und filigran anmutende Gargutträgeraufnahme, die aus nur wenig tragenden Rahmenelementen gebildet ist und lediglich über die Führungselemente miteinander verbunden ist.The frame element is preferably formed from at least one vertical wire element, in particular from two wire elements arranged essentially parallel to one another. This enables a particularly simple and filigree-looking food support receptacle, which is formed from frame elements that bear little load and are only connected to one another via the guide elements.

Gemäß einer Variante ist das Rahmenelement aus einem umlaufenden Rahmen gebildet. Diese Variante ermöglicht ein besonders stabiles Rahmenelement, bestehend aus senkrechten Drahtelementen sowie rechtwinkelig dazu angeordneten waagrechten Drahtelementen, welche in Summe den umlaufenden Rahmen bilden. Bei dieser Variante sind die Prägungen alternativ oder zusätzlich an den waagrecht verlaufenden Drahtelementen angeordnet. Die Führungselemente sind an den senkrecht verlaufenden Rahmenelementen angebracht. Das umlaufende Rahmenelement ist aus separaten Drahtelementen gefügt oder aus einem fortlaufenden Halbzeug gefertigt, welches rahmenartig gebogen ist. Die Verbindungsstellen der Rahmenelemente sowie Anknüpfungspunkte zu den Führungselementen sind vorzugsweise geschweißt.According to a variant, the frame element is formed from a peripheral frame. This variant enables a particularly stable frame element, consisting of vertical wire elements and horizontal wire elements arranged at right angles thereto, which together form the surrounding frame. In this variant, the embossings are arranged alternatively or additionally on the horizontally running wire elements. The guide elements are attached to the vertically running frame elements. The peripheral frame element is joined from separate wire elements or made from a continuous semi-finished product which is bent like a frame. The connection points of the frame elements and attachment points to the guide elements are preferably welded.

Vorzugsweise nimmt das Rahmenelement zumindest ein Führungselement auf, das aus wenigstens einem im Wesentlichen waagrechten Drahtelement, insbesondere aus zwei im Wesentlichen parallel zueinander angeordneten Drahtelementen gebildet ist. Dabei besteht das Führungselement ein oberes und ein unteres Führungselement auf, wobei auf dem unteren Führungselement der Gargutträger aufliegt und gleitet. Das obere Führungselement verhindert in der Auszugsbewegung das Kippen des Gargutträgers. Alternativ ist das Führungselement aus einem schienenartigen Auszugssystem gebildet, das am Rahmenelement befestigt ist. Gemäß einer weiteren Variante ist die Gargutträgeraufnahme lediglich von punktuellen Befestigungspunkten, beispielsweise Pins gebildet, welche den Gargutträger aufnehmen.The frame element preferably accommodates at least one guide element, which is formed from at least one essentially horizontal wire element, in particular from two wire elements arranged essentially parallel to one another. The guide element consists of an upper and a lower guide element, the food support resting and sliding on the lower guide element. The upper guide element prevents the food rack from tipping over during the pull-out movement. Alternatively, the guide element is formed from a rail-like pull-out system that is attached to the frame element. According to a further variant, the food support receptacle is formed only by punctiform attachment points, for example pins, which accommodate the food support.

Die Erfindung löst die Aufgabe zusätzlich mit einem Gargerät, aufweisend eine vorangegangen beschriebene Gargutträgeraufnahme.The invention also achieves the object with a cooking appliance having a food support receptacle as described above.

The food support receptacle 5 has different insertion heights, which space the food support 6 at different levels in the food compartment 2 from the heating elements.

Fig. 2 zeigt eine perspektivische Ansicht der Gargutträgeraufnahme 5 gemäß dem bekannten Stand der Technik. Fig. 2 zeigt den aus Benutzersicht gesehenen linken Abschnitt des Garraums 2, an dessen linke Seitenwand 3 eine linke Gargutträgeraufnahme 5 befestigt ist. Diese Gargutträgeraufnahme 5 besteht aus zwei im Wesentlichen parallel zueinander angeordnet und senkrecht verlaufenden Rahmenelementen 7, die ein unteres Führungselement 8 und ein oberes Führungselement 9 derart tragen, dass ein Gargutträger zwischen den Führungselementen 8, 9 ein- und ausziehbar gelagert ist. Zur Beabstandung der Gargutträgeraufnahme 5 zur Seitenwand 3 weist das Rahmenelement 7 mehrere Abstandshalter 10 auf. Gemäß dem Stand der Technik können diese Abstandshalter 10 als Verlängerungen 10a der Führungselemente 8, 9 oder als gebogene Abschnitte 10b aus dem Rahmenelement gebildet sein. 2 shows a perspective view of the food support receptacle 5 according to the known prior art. 2 shows the left-hand section of the cooking chamber 2 seen from the user's point of view, on the left-hand side wall 3 of which a left-hand food support receptacle 5 is fastened. This food support receptacle 5 consists of two substantially parallel and perpendicular frame elements 7 which carry a lower guide element 8 and an upper guide element 9 in such a way that a food support can be pulled in and out between the guide elements 8, 9. The frame element 7 has a plurality of spacers 10 for spacing the food support receptacle 5 from the side wall 3 . According to the prior art, these spacers 10 can be formed as extensions 10a of the guide elements 8, 9 or as bent sections 10b from the frame element.

Fig. 3 zeigt eine perspektivische Ansicht der Gargutträgeraufnahme 5 gemäß der vorliegenden Erfindung. Dabei ist eine linke Gargutträgeraufnahme 5 zu sehen, welche an der linken Seitenwand 3 des Garraums befestigt ist. Die nicht näher gezeigte und beschriebene Befestigung der Gargutträgeraufnahme 5 im Garraum 2 erfolgt über Verschraubung, Verschweißen, Verprägen oder Klippbefestigungen, wie z. B. mittels Buchsen. In diesem Ausführungsbeispiel ist das Rahmenelement 7 der Gargutträgeraufnahme 5 aus zwei im Wesentlichen parallel verlaufenden und senkrecht ausgerichteten Drahtelementen gebildet. Das Rahmenelement 7 dient zur Aufnahme der Führungselemente 7, 8, wobei das untere Führungselement 8 zur Aufnahme des Gargutträgers 6 und das obere Führungselement 9 zur Vermeidung des Kippens des Gargutträgers 6 dient. Um die Gargutträgeraufnahme 5 sicher und gleichzeitig verschleißarm zur Seitenwand 3 zu beabstanden, sind erfindungsgemäße Abstandshalter 10 angebracht. Diese Abstandshalter 10 werden aus dem Rahmenelement 7 geprägt, wobei das Material des Rahmenelements 7 materialverdrängend zur Bildung des Abstandshalters 10 genutzt wird. Im gezeigten Ausführungsbeispiel sind die Abstandshalter 10 paarweise an gegenüberliegenden Rahmenelementen angeordnet. Das Ausführungsbeispiel zeigt zwei übereinanderliegende Abstandshalter 10 am Rahmenelement, so dass sich in Summe vier Abstandshalter 10 an der Gargutträgeraufnahme 5 befinden. Alternativ dazu sind Varianten mit ein, zwei, drei oder mehreren Abstandshaltern 10 je Gargutträgeraufnahme 5 möglich. In Abhängigkeit der Gestaltung der Seitenwände 3 sind die Abstandshalter 10 so in Längsrichtung des Rahmenelements 7 angeordnet, dass sie nicht an Sicken, Nuten oder anderen Unebenheiten der Garraumseitenwand 3 anliegen. Dies ermöglicht eine besonders ebene Anlage der Gargutträgeraufnahme 5 an der Seitenwand, was zu besonders stabil befestigten Gargutträgeraufnahmen 5 führen. Der Abstandshalter 10 wird durch zumindest eine Prägung aus dem Rahmenelement 7 geprägt, wobei der materialverdrängende Bearbeitungsschnitt eine Quetschung in Richtung Seitenwand 3 erzeugt, die als Abstandshalter der Gargutträgeraufnahme 5 zur Seitenwand 3 dient. Diese Quetschung wird durch ein Einprägen erzeugt. Dabei verursacht beispielsweise ein Stempel keinerlei scharfe Kanten, die zu einer Verletzung der Oberfläche der Seitenwand 3, z. B. in einer Emailschicht führen. Das vorgesehene Prägeverfahren erzeugt durch die materialverdrängende Fertigung sanfte Konturen und Radien, die zudem Verletzungsrisiken des Nutzers beim Reinigen oder Montieren der Gargutträgeraufnahme 5 verhindern. In Abhängigkeit des Werkzeugs ist die Kontur der Prägung geformt. 3 shows a perspective view of the food support receptacle 5 according to the present invention. A left-hand food support receptacle 5 can be seen, which is fastened to the left-hand side wall 3 of the cooking space. The attachment of the food support receptacle 5 in the cooking chamber 2, which is not shown and described in detail, takes place via screwing, welding, embossing or clip attachments, e.g. B. by means of sockets. In this exemplary embodiment, the frame element 7 of the food support receptacle 5 is formed from two essentially parallel and vertically aligned wire elements. The frame element 7 serves to hold the guide elements 7, 8, the lower guide element 8 serving to hold the food support 6 and the upper guide element 9 to prevent the food support 6 from tipping over. Spacers 10 according to the invention are attached in order to space the food support receptacle 5 securely and at the same time with little wear and tear from the side wall 3 . These spacers 10 are embossed from the frame element 7 , the material of the frame element 7 being used to form the spacer 10 in a material-displacing manner. In the exemplary embodiment shown, the spacers 10 are arranged in pairs on opposite frame elements. The exemplary embodiment shows two spacers 10 lying one above the other on the frame element, so that there are a total of four spacers 10 on the food support receptacle 5 . As an alternative to this, variants with one, two, three or more spacers 10 for each food support receptacle 5 are possible. Depending on the design of the side walls 3, the spacers 10 are arranged in the longitudinal direction of the frame element 7 in such a way that they do not rest against beads, grooves or other bumps in the side wall 3 of the cooking chamber. This allows the food support receptacle 5 to rest particularly flat against the side wall, which leads to the food support receptacles 5 being fastened in a particularly stable manner. The spacer 10 is embossed from the frame element 7 by at least one embossing, the material-displacing processing cut producing a pinch in the direction of the side wall 3 , which serves as a spacer between the food support receptacle 5 and the side wall 3 . This pinch is created by an embossing. In this case, for example, a stamp does not cause any sharp edges that could damage the surface of the side wall 3, e.g. B. lead in an enamel layer. The envisaged embossing process produces gentle contours and radii through the material-displacing production, which also prevent the user from injuring himself when cleaning or assembling the food support receptacle 5 . The contour of the embossing is shaped depending on the tool.

In Fig. 4 wird die Prägung mittels einem symmetrischen, runden Stempels erzeugt, der auf den runden Draht des Rahmenelements 7 gepresst wird. Eine besonders gute Prägung wird erzeugt, wenn die Quetschung gleichzeitig von zwei Seiten aus, symmetrisch zum Draht erfolgt. Dabei bildet sich zwischen den beiden Anpressflächen 11 eine Anlagefläche 12, welche als Kontaktfläche zur Seitenwand 3 ausgebildet ist. In einer weiteren nicht dargestellten Ausführungsform des Abstandshalters 10 ist die Anlagefläche 12 in der Art konvex also zur Seitenwand 3 hin bauchig ausgebildet, dass eine punktuelle Kontaktierung des Abstandshalters 10 an der Seitenwand 3 erfolgt.In 4 the embossing is produced by means of a symmetrical, round punch, which is pressed onto the round wire of the frame element 7. A particularly good embossing is produced when the pinching is carried out simultaneously from two sides, symmetrically to the wire. A contact surface 12 is formed between the two contact surfaces 11 and is designed as a contact surface to the side wall 3 . In a further embodiment of the spacer 10 that is not shown, the contact surface 12 is convex in the manner, that is, bulged toward the side wall 3 , so that the spacer 10 contacts the side wall 3 at points.

Fig. 5 zeigt eine perspektivische Detailansicht des Abstandshalters 10 gemäß einer zweiten Variante. Dabei ist die Prägung in der Art ausgeführt, dass sich eine längliche Quetschung in Form eines Langlochs ergibt. Dabei bildet sich ein Abstandshalter 10 mit einer besonders großen Auflagefläche 12, welche die Gargutträgeraufnahme 5 ohne Kratzer und Emailabplatzer an der Seitenwand 3 positioniert. figure 5 shows a perspective detailed view of the spacer 10 according to a second variant. In this case, the embossing is carried out in such a way that an elongate squeeze results in the form of a slot. In this way, a spacer 10 is formed with a particularly large support surface 12, which positions the food support receptacle 5 on the side wall 3 without scratches or chipped enamel.
