Description

KüchengerätKitchen appliance

Die Erfindung betrifft ein Küchengerät der im Oberbegriff des Patentanspruchs 1 genannten Art.The invention relates to a kitchen appliance of the type mentioned in the preamble of claim 1.

Küchengeräte sind aus dem Stand der Technik in vielfachen Ausführungsformen bekannt. Beispielsweise sind aus den Druckschriften GB 2478531 A , WO 98/45021 A1 und CN 10542338 A Dunstabzugshauben mit einem entnehmbaren Fettfilter bekannt. Der Fettfilter ist in einem Betriebszustand der Dunstabzugshaube mittels mindestens eines Montagemittels an einem Tragteil der Dunstabzugshaube derart fix montiert ist, dass die Dunstabzugshaube betriebsbereit ist. Zwecks Reinigung oder Austausch ist der Fettfilter in einem Wartungszustand der Dunstabzugshaube von dem Tragteil der Dunstabzugshaube entnehmbar. Damit der Fettfilter nicht in ungewünschter Weise herunterfällt, ist es vorgesehen, dass der Fettfilter mittels mindestens eines Haltemittels in einer Wartungslage des Fettfilters an dem Tragteil gehalten ist. Bei der Wartungslage kann es sich beispielsweise um eine Zwischenlage des Fettfilters handeln, bevor dieser in kontrollierter Weise vollständig von dem Tragteil gelöst wird.Kitchen appliances are known from the prior art in numerous embodiments. For example, from the publications GB 2478531 A , WO 98/45021 A1 and CN 10542338 A Cooker hoods known with a removable grease filter. In an operating state of the extractor hood, the grease filter is fixedly mounted on a support part of the extractor hood by means of at least one assembly means in such a way that the extractor hood is ready for operation. For the purpose of cleaning or replacement, the grease filter can be removed from the support part of the extractor hood when the extractor hood is in a maintenance state. So that the grease filter does not fall down in an undesired manner, it is provided that the grease filter is held by means of at least one holding means in a maintenance position of the grease filter on the support part. The maintenance layer can be, for example, an intermediate layer of the grease filter before it is completely detached from the support part in a controlled manner.

Ein gattungsgemäßes Küchengerät ist aus der Druckschrift WO 03/054451 A1 bekannt. Ein ähnliches Befestigungskonzept ist in der Druckschrift DE 202009005586 U1 offenbart.A generic kitchen appliance is from the publication WO 03/054451 A1 known. A similar fastening concept is given in the publication DE 202009005586 U1 disclosed.

Ferner sind als Kochfelder ausgebildete Küchengeräte bekannt, die beispielsweise als Einbaukochfeld ausgebildet und in ein Küchenmöbel eingebaut sind. Die Druckschrift DE 20 2017 005 503 U1 zeigt ein solches Kochfeld. Die bekannten Kochfelder weisen ein Tragteil und ein an dem Tragteil befestigbares Gehäuse zur Aufnahme von weiteren Komponenten des Kochfelds auf. Die weiteren Komponenten des Kochfelds sind beispielsweise Heizkörper und Elektronik. In einem Betriebszustand des Kochfelds ist das Gehäuse mit den weiteren Komponenten mittels Montagemitteln an dem Tragteil derart fix montiert, dass das Kochfeld betriebsbereit ist. In einem Wartungszustand des Kochfelds ist der Zugriff auf die in dem Gehäuse angeordneten weiteren Komponenten des Kochfelds bei dann in einer Wartungslage befindlichen Gehäuse ermöglicht. Dies ist beispielsweise erforderlich, wenn das Kochfeld repariert werden muss.Furthermore, kitchen appliances designed as hobs are known which are designed, for example, as built-in hobs and built into kitchen furniture. The pamphlet DE 20 2017 005 503 U1 shows such a hob. The known hobs have a support part and a housing that can be fastened to the support part for receiving further components of the hob. The other components of the hob are, for example, radiators and electronics. In an operating state of the hob, the housing with the further components is fixedly mounted on the support part by means of assembly means in such a way that the hob is ready for operation. In a maintenance state of the hob, access to the further components of the hob arranged in the housing is made possible when the housing is then in a maintenance position. This is necessary, for example, if the hob needs to be repaired.

Andere Formen von Küchengeräten sind solche, die nicht fest in der Küche eingebaut sind, sondern mobil auf einer Arbeitsplatte angeordnet werden. Ein derartiges Küchengerät zeigt beispielsweise die Druckschrift US 4,977,884 A .Other forms of kitchen appliances are those that are not permanently installed in the kitchen, but are arranged on a worktop in a mobile manner. Such a kitchen appliance is shown, for example, in the publication U.S. 4,977,884 A .

Darüber hinaus sind auch andere Küchengeräte für den privaten Betrieb in einem Haushalt oder für den professionellen Betrieb in einer Großküche oder dergleichen bekannt.In addition, other kitchen appliances for private use in a household or for professional use in a large kitchen or the like are known.

Der Erfindung stellt sich somit das Problem, die Handhabung eines Küchengeräts in einem Wartungsfall zu verbessern.The invention thus poses the problem of improving the handling of a kitchen appliance in the event of maintenance.

Erfindungsgemäß wird dieses Problem durch ein Küchengerät mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a kitchen appliance with the features of claim 1. Advantageous refinements and developments of the invention emerge from the following subclaims.

Der mit der Erfindung erreichbare Vorteil besteht insbesondere darin, dass die Handhabung eines Küchengeräts in einem Wartungsfall verbessert ist. Aufgrund des erfindungsgemäßen Küchengeräts, wobei das Haltemittel einen flexiblen Schaft aufweist, an dessen Enden jeweils ein Verbindungsmittel zur Verbindung des Haltemittels mit dem Tragteil und dem beweglichen Teil ausgebildet ist, ist die Handhabung eines derartigen Haltemittels beziehungsweise eines damit ausgestatteten Küchengeräts in einem Wartungsfall wesentlich erleichtert. Ein ungewünschtes Verklemmen bei der Überführung des Küchengeräts von dessen Betriebszustand in dessen Wartungszustand oder umgekehrt ist durch die Flexibilität des Haltemittels weitestgehend verhindert. Darüber hinaus ist dadurch die gestalterische Freiheit bei dem Küchengerät verbessert, so dass das Tragteil und das bewegliche Teil nach Art, Material, Dimensionierung, Formgebung und Anordnung in weiten geeigneten Grenzen frei wählbar sind. Beispielsweise sind dadurch auch bewegliche Teile mit großen Dimensionen oder einem hohen Gewicht leichter handhabbar. Entsprechend ist der Einsatz von Werkzeug und Personal im Wartungsfall auch bei derartigen Küchengeräten reduziert.The advantage that can be achieved with the invention is in particular that the handling of a kitchen appliance is improved in the event of maintenance. Due to the kitchen appliance according to the invention, the holding means having a flexible shaft, at the ends of which a connecting means for connecting the holding means to the support part and the movable part is formed, the handling of such a holding means or a kitchen appliance equipped with it is significantly easier in a maintenance case. Undesired jamming when transferring the kitchen appliance from its operating state to its maintenance state or vice versa is largely prevented by the flexibility of the holding means. In addition, the design freedom of the kitchen appliance is improved as a result, so that the support part and the movable part can be freely selected within wide suitable limits in terms of type, material, dimensions, shape and arrangement. For example, moving parts with large dimensions or a high weight are easier to handle as a result. Correspondingly, the use of tools and personnel in the case of maintenance is also reduced with such kitchen appliances.

Grundsätzlich ist die Verbindung des Tragteils mit dem beweglichen Teil mittels des Haltemittels nach Art, Funktionsweise, Material, Dimensionierung, Anordnung und Anzahl in weiten geeigneten Grenzen frei wählbar. Eine besonders vorteilhafte Weiterbildung des erfindungsgemäßen Küchengeräts sieht vor, dass mindestens eine Paarung zueinander korrespondierender Verbindungsmittel als lösbare Verbindungsmittel zur lösbaren Verbindung ausgebildet sind. Hierdurch ist das bewegliche Teil in dessen Wartungslage von dem Tragteil lösbar. Zum einen ist dadurch beispielsweise der Zugriff auf das bewegliche Teil und etwaige daran angeordnete weitere Komponenten des Küchengeräts und/oder auf das Tragteil und etwaige daran angeordnete weitere Komponenten des Küchengeräts verbessert. Zum anderen ist es möglich, das bewegliche Teil separat von dem Tragteil zu behandeln, beispielsweise das bewegliche Teil in einer Geschirrspülmaschine oder dergleichen zu reinigen.In principle, the connection of the support part to the movable part by means of the holding means can be freely selected within wide suitable limits in terms of type, mode of operation, material, dimensioning, arrangement and number. A particularly advantageous development of the kitchen appliance according to the invention provides that at least one pair of mutually corresponding connecting means are designed as releasable connecting means for releasable connection. As a result, the movable part can be detached from the support part in its maintenance position. On the one hand, this improves, for example, access to the movable part and any further components of the kitchen appliance arranged thereon and / or to the support part and any further components of the kitchen appliance arranged thereon. On the other hand, it is possible to treat the movable part separately from the support part, for example to clean the movable part in a dishwasher or the like.

The kitchen appliance 2 is designed as an extractor hood and comprises a supporting part designed as an extractor hood housing and a movable part 4 that can be fastened to the supporting part, the movable part 4 being designed as a grease filter of the kitchen appliance 2. The support part is in the Figs. 1 to 4 not shown. In one in the Figs. 1 to 4 operating state of the kitchen appliance 2 shown, the movable part 4 is fixedly mounted on the support part by means of at least one mounting means (not shown) in such a way that the kitchen appliance 2 is ready for operation. In a maintenance state, not shown, of the kitchen appliance 2, the movable part 4 is held by means of a holding means 6 in a maintenance position of the movable part 4 on the support part, the holding means 6 having a flexible shaft 8, at the ends of which each have a connecting means 10, 12 for connection of the holding means 6 is formed with the support part and the movable part 4. The support part has a connection means corresponding to the connection means 10 of the holding means 6 and the movable part 4 has a connection means 14 corresponding to the connection means 12. The connecting means of the support part is not shown. In the present exemplary embodiment, the connection means 10 of the holding means 6 are paired with the corresponding connection means of the support part (not shown) and the connection means 12 of the holding means 6 are paired with the connection means 14 of the movable part 4 corresponding thereto.

Das Verbindungsmittel 10 des Haltemittels 6 ist als eine Schlinge des als Seil ausgebildeten flexiblen Schafts 8 des Haltemittels 6 ausgebildet und ist mittels des als Schraubhaken ausgebildeten zu dem Verbindungsmittel 10 korrespondierenden Verbindungsmittels des Tragteils in dem Betriebszustand und in dem Wartungszustand des Küchengeräts 2 formschlüssig und fest mit dem Tragteil verbunden.The connecting means 10 of the holding means 6 is designed as a loop of the flexible shaft 8 of the holding means 6, which is designed as a rope, and is positively and firmly connected by means of the connecting means of the supporting part, which corresponds to the connecting means 10, in the operating state and in the maintenance state of the kitchen appliance 2 connected to the supporting part.

Das Verbindungsmittel 12 des Haltemittels 6 ist als ein Formschlusskörper, nämlich als ein kugelförmiger Kloben, ausgebildet und ist mittels des als Formschlusselement, nämlich als eine kulissenartige Öffnung, ausgebildeten zu dem Verbindungsmittel 12 korrespondierenden Verbindungsmittels 14 des beweglichen Teils 4 in dem in den Fig. 1 bis 4 dargestellten Betriebszustand des Küchengeräts 2 formschlüssig und fest mit dem beweglichen Teil 4 verbunden. Das Verbindungsmittel 14, nämlich die kulissenartige Öffnung, weist einen Durchführungsabschnitt 16 zur lösbaren Durchführung des als Formschlusskörper ausgebildeten Verbindungsmittels 12 in einer Durchführungslage des Verbindungsmittels 12, einen Überführungsabschnitt 18 zur nicht lösbaren Überführung des Verbindungsmittels 12 von dessen Durchführungslage in eine Haltelage des Verbindungsmittels 12 und einen Halteabschnitt 20 zur formschlüssigen Halterung des beweglichen Teils 4 an dem Tragteil in der Haltelage des Verbindungsmittels 12 auf. Siehe hierzu die Fig. 2 und 3, in denen jeweils eine Detailansicht in dem Bereich des Haltemittels 6 dargestellt ist.The connecting means 12 of the holding means 6 is designed as a form-locking body, namely as a spherical block, and is formed as a form-locking element, namely as a link-like opening, corresponding to the connecting means 12 connecting means 14 of the movable part 4 in the in the Figs. 1 to 4 The illustrated operating state of the kitchen appliance 2 is positively and firmly connected to the movable part 4. The connecting means 14, namely the link-like opening, has a lead-through section 16 for the releasable lead-through of the connecting means 12 designed as a form-fit body in a lead-through position of the connecting means 12, a transfer section 18 for the non-releasable transfer of the connecting means 12 from its lead-through position into a holding position of the connecting means 12 and a Holding section 20 for the form-fitting holding of the movable part 4 on the support part in FIG the holding position of the connecting means 12. See the Fig. 2 and 3 , in each of which a detailed view in the area of the holding means 6 is shown.

Der Durchführungsabschnitt 16 des als kulissenartige Öffnung ausgebildeten Verbindungsmittels 14 des beweglichen Teils 4 ist als eine kreisförmige Öffnung mit einem Durchmesser ausgebildet, der größer als der Durchmesser des als kugelförmiger Kloben ausgebildeten Verbindungsmittels 12 ist. Entsprechend lässt sich das Verbindungsmittel 12 in dessen Durchführungslage von dem beweglichen Teil 4 des Küchengeräts 2 lösen. Der Überführungsabschnitt 18 ist als eine den Durchführungsabschnitt 16 mit dem Halteabschnitt 20 verbindende längliche Öffnung ausgebildet, deren Breite geringer als der Durchmesser des Verbindungsmittels 12 und größer als die Dicke des als Seil ausgebildeten flexiblen Schafts 8 des Haltemittels 6 ist. Der Halteabschnitt 20 des als kulissenartige Öffnung ausgebildeten Verbindungsmittels 14 des beweglichen Teils 4 ist als eine Vertiefung des beweglichen Teils 4 ausgebildet. Die Vertiefung des beweglichen Teils 4 ist beispielsweise als eine Prägung des beweglichen Teils 4 kostengünstig und robust realisierbar.The lead-through section 16 of the connecting means 14 of the movable part 4, which is designed as a link-like opening, is designed as a circular opening with a diameter that is larger than the diameter of the connecting means 12, which is designed as a spherical block. Correspondingly, the connecting means 12 can be released from the movable part 4 of the kitchen appliance 2 in its lead-through position. The transfer section 18 is designed as an elongated opening connecting the feed-through section 16 to the holding section 20, the width of which is smaller than the diameter of the connecting means 12 and greater than the thickness of the flexible shaft 8 of the holding means 6, which is designed as a rope. The holding section 20 of the connecting means 14 of the movable part 4, which is designed as a link-like opening, is designed as a recess in the movable part 4. The recess of the movable part 4 can be implemented cost-effectively and robustly, for example, as an embossing of the movable part 4.

Ferner ist an dem beweglichen Teil 4 ein als Federplatte, nämlich als Federblech, ausgebildetes Sicherungsmittel 22 zur Sicherung des als kugelförmiger Kloben ausgebildeten Verbindungsmittels 12 in dessen Haltelage derart angeordnet, dass das als Federplatte ausgebildete Sicherungsmittel 22 auf das als kugelförmiger Kloben ausgebildete Verbindungsmittel 12 des Haltemittels 6 in dessen Haltelage eine in Richtung der Vertiefung gerichtete Federkraft ausübt. Das als Federblech ausgebildete Sicherungsmittel 22 ist in den Fig. 3 und 4 deutlich erkennbar.Furthermore, a securing means 22 designed as a spring plate, namely as a spring plate, for securing the connecting means 12 designed as a spherical clamp in its holding position is arranged on the movable part 4 in such a way that the securing means 22 designed as a spring plate onto the connecting means 12 designed as a spherical clamp of the holding means 6 in its holding position exerts a spring force directed in the direction of the recess. The locking means 22, which is designed as a spring plate, is in the Fig. 3 and 4th clearly.

Im Nachfolgenden wird die Funktionsweise des erfindungsgemäßen Küchengeräts 2 gemäß dem vorliegenden ersten Ausführungsbeispiel anhand der Fig. 1 bis 4 näher erläutert.In the following, the mode of operation of the kitchen appliance 2 according to the invention according to the present first exemplary embodiment is illustrated with reference to FIG Figs. 1 to 4 explained in more detail.

In dem in den Fig. 1 bis 4 dargestellten Betriebszustand des als Dunstabzugshaube ausgebildeten Küchengeräts 2 ist das als Fettfilter ausgebildete bewegliche Teil 4 mittels mindestens eines nicht dargestellten Montagemittels an dem als Dunstabzugshaubengehäuse ausgebildeten, ebenfalls nicht dargestellten Tragteil derart fix montiert, dass das Küchengerät 2 auf dem Fachmann bekannte Weise betrieben werden kann. Ist es nun erforderlich, das bewegliche Teil 4 von dem Tragteil zu demontieren, also das Küchengerät 2 von dessen Betriebszustand in dessen Wartungszustand zu überführen, löst ein Benutzer das mindestens eine Montagemittel, beispielsweise eine Verschraubung, eine Rastverbindung oder dergleichen. Aufgrund des Eigengewichts senkt sich das bewegliche Teil 4 nach unten. Damit das bewegliche Teil 4 nicht in ungewünschter Weise herunterfällt und beispielsweise ein darunter angeordnetes, nicht dargestelltes Kochfeld beschädigt, weist das erfindungsgemäße Küchengerät 2 das Haltemittel 6 auf. Das Haltemittel 6 ist sowohl in dem dargestellten Betriebszustand wie auch in dem nicht dargestellten Wartungszustand des Kochgeräts 2 mit dem Tragteil fest verbunden. Hierzu weist das Haltemittel 6 das als Schlinge ausgebildete Verbindungsmittel 10 und das Tragteil ein dazu korrespondierendes und als Schraubhaken ausgebildetes, nicht dargestelltes Verbindungsmittel auf.In the in the Figs. 1 to 4 The operating state of the kitchen appliance 2, which is designed as an extractor hood, is the movable part 4, which is designed as a grease filter, by means of at least one mounting means, not shown, on the supporting part designed as an extractor hood housing, also not shown, in such a way that the kitchen appliance 2 can be operated in a manner known to a person skilled in the art. If it is now necessary to dismantle the movable part 4 from the support part, i.e. to transfer the kitchen appliance 2 from its operating state to its maintenance state, a user releases the at least one assembly means, for example a screw connection, a latching connection or the like. Due to its own weight, the movable part 4 is lowered. So that the movable part 4 does not fall down in an undesired manner and, for example, damage a hob (not shown) arranged underneath, the kitchen appliance 2 according to the invention has the holding means 6. The holding means 6 is both in the operating state shown and in the not illustrated maintenance condition of the cooking device 2 firmly connected to the support part. For this purpose, the holding means 6 has the connecting means 10 designed as a loop and the support part has a connecting means (not shown) that corresponds to this and designed as a screw hook.

Aufgrund des Eigengewichts des beweglichen Teils 4 sinkt das bewegliche Teil 4 lediglich bis zu dessen Wartungslage ab, in der das bewegliche Teil 4 mittels des Haltemittels 6 an dem Tragteil gehalten ist. Hierzu weist das Haltemittel 6 das als kugelförmiger Kloben ausgebildete Verbindungsmittel 12 und das bewegliche Teil 4 das dazu korrespondierende und als kulissenartige Öffnung ausgebildete Verbindungsmittel 14 auf. In dem Wartungszustand des Küchengeräts 2 und damit in der dazu korrelierenden Wartungslage des beweglichen Teils 4 ist das bewegliche Teil 4 durch das Haltemittel 6 sicher an dem Tragteil gehalten. Das Verbindungsmittel 12 befindet sich in dessen Haltelage in dem Halteabschnitt 20 des Verbindungsmittels 14, wobei das Verbindungsmittel 12 mittels einer von dem Sicherungsmittel 22 auf das Verbindungsmittel 12 in dessen Haltelage ausgeübten Federkraft, sicher in dessen Haltelage gehalten ist. Möchte der Benutzer nun das bewegliche Teil 4, beispielsweise zu dessen Reinigung in einer Geschirrspülmaschine oder dergleichen, von dem Tragteil entnehmen, muss der Benutzer das Verbindungsmittel 12, nämlich den kugelförmigen Kloben, lediglich gegen die Federkraft des Sicherungsmittels 22 aus dem als Vertiefung ausgebildeten Halteabschnitt 20 herausführen und mittels des Überführungsabschnitts 18 in den Durchführungsabschnitt 16 des Verbindungsmittels 14 des beweglichen Teils 4 überführen. Erst in dessen Durchführungslage ist das als kugelförmiger Kloben ausgebildete Verbindungsmittel 12 des Haltemittels 6 aus dem als kulissenartige Öffnung ausgebildeten Verbindungsmittel 14 des beweglichen Teils 4 herausnehmbar. Entsprechend lässt sich das bewegliche Teil 4 in kontrollierter Weise von dem Benutzer in der Durchführungslage des Verbindungsmittels 12 von dem Tragteil des Küchengeräts 2 entnehmen. Das Haltemittel 6 verbleibt an dem Tragteil.Due to the weight of the movable part 4, the movable part 4 only sinks down to its maintenance position, in which the movable part 4 is held on the support part by means of the holding means 6. For this purpose, the holding means 6 has the connecting means 12 designed as a spherical block and the movable part 4 has the connecting means 14 corresponding to this and designed as a link-like opening. In the maintenance state of the kitchen appliance 2 and thus in the maintenance position of the movable part 4 that correlates therewith, the movable part 4 is securely held on the support part by the holding means 6. The connecting means 12 is in its holding position in the holding section 20 of the connecting means 14, the connecting means 12 being securely held in its holding position by means of a spring force exerted by the securing means 22 on the connecting means 12 in its holding position. If the user would now like to remove the movable part 4 from the support part, for example to clean it in a dishwasher or the like, the user only has to remove the connecting means 12, namely the spherical clamp, against the spring force of the securing means 22 from the holding section 20 designed as a recess out and transfer by means of the transfer section 18 into the lead-through section 16 of the connecting means 14 of the movable part 4. The connecting means 12 of the holding means 6, which is designed as a spherical block, can only be removed from the connecting means 14, which is designed as a link-like opening, of the movable part 4 in its lead-through position. Accordingly, the movable part 4 can be removed in a controlled manner by the user in the lead-through position of the connecting means 12 from the support part of the kitchen appliance 2. The holding means 6 remains on the support part.

Zwecks Rücküberführung des Küchengeräts 2 in dessen Betriebszustand verbindet der Benutzer das bewegliche Teil 4 wieder mittels des Haltemittels 6 mit dem Tragteil, indem der Benutzer das als kugelförmiger Kloben ausgebildete Verbindungsmittel 12 des Haltemittels 6 in dessen Durchführungslage in den Durchführungsabschnitt 16 des Verbindungsmittels 14 des beweglichen Teils 4 hindurchsteckt und mittels des Überführungsabschnitts 18 bis in den Halteabschnitt 20 des Verbindungsmittels 14 schiebt. Dies geschieht gegen die Federkraft des Sicherungsmittels 22. Sobald das Verbindungsmittel 12 des Haltemittels 6 den Halteabschnitt 20 erreicht hat, drückt die Federkraft des Sicherungsmittels 22 das Verbindungsmittel 12 in dessen Haltelage, nämlich in den als Vertiefung ausgebildeten Halteabschnitt 20 des Verbindungsmittels 14. Das bewegliche Teil 4 befindet sich in dessen Wartungslage und das Küchengerät 2 befindet sich in dessen zu der Wartungslage des beweglichen Teils 4 korrelierenden Wartungszustand. Der Benutzer montiert das bewegliche Teil 4 mittels des mindestens einen Montagemittels an dem Tragteil. Das Küchengerät 2 befindet sich wieder in dem in den Fig. 1 bis 4 dargestellten Betriebszustand des Küchengeräts 2.For the purpose of returning the kitchen appliance 2 to its operating state, the user reconnects the movable part 4 to the support part by means of the holding means 6 by placing the connecting means 12 of the holding means 6 in its lead-through position in the lead-through section 16 of the connecting means 14 of the movable part 4 pushes through and by means of the transfer section 18 pushes it into the holding section 20 of the connecting means 14. This takes place against the spring force of the securing means 22. As soon as the connecting means 12 of the holding means 6 has reached the holding section 20, the spring force of the securing means 22 pushes the connecting means 12 into its holding position, namely in the holding section 20 of the connecting means 14, which is designed as a recess 4 is in its maintenance position and the kitchen appliance 2 is in its maintenance position of the moving part 4 correlating maintenance condition. The user mounts the movable part 4 on the support part by means of the at least one mounting means. The kitchen appliance 2 is again in the Figs. 1 to 4 illustrated operating state of the kitchen appliance 2.

Nachfolgend sind zwei weitere Ausführungsbeispiele des erfindungsgemäßen Haltemittels und des erfindungsgemäßen Küchengeräts beschrieben, wobei lediglich die von dem ersten Ausführungsbeispiel abweichenden Merkmale explizit erläutert sind. Gleiche oder gleichwirkende Bauteile sind mit den gleichen Bezugszeichen wie bei dem ersten Ausführungsbeispiel gekennzeichnet.Two further exemplary embodiments of the holding means according to the invention and the kitchen appliance according to the invention are described below, only the features that differ from the first exemplary embodiment being explicitly explained. Components that are the same or have the same effect are identified by the same reference symbols as in the first exemplary embodiment.

In Fig. 5 ist ein zweites Ausführungsbeispiel eines erfindungsgemäßen Küchengeräts 2 teilweise dargestellt. Das Küchengerät 2 ist als ein Einbaukochfeld mit Induktionsbeheizung ausgebildet und weist ein als Kochfeldrahmen ausgebildetes Tragteil 3 und ein an dem Tragteil 3 befestigbares und als Gehäuse ausgebildetes bewegliches Teil 4 zur Aufnahme von weiteren Komponenten des Kochfelds auf. Die weiteren Komponenten sind in der Fig. 5 nicht näher dargestellt. Hierbei könnte es sich beispielsweise um Heizkörper, Elektrik und Elektronik des Kochfelds handeln. Das Kochfeld ist auf dem Fachmann bekannte Weise in ein Küchenmöbel, nämlich einen Unterschrank mit einer Tür, eingebaut. Entsprechend ist das bewegliche Teil 4 von unten, also von dem Inneren des Unterschranks her, zugänglich. Das Küchenmöbel, also der Unterschrank, ist nicht dargestellt.In Fig. 5 a second embodiment of a kitchen appliance 2 according to the invention is partially shown. The kitchen appliance 2 is designed as a built-in hob with induction heating and has a support part 3 designed as a hob frame and a movable part 4, which can be fastened to the support part 3 and designed as a housing, for receiving further components of the hob. The other components are in the Fig. 5 not shown in detail. This could be, for example, radiators, electrics and electronics of the hob. The hob is built into kitchen furniture, namely a base cabinet with a door, in a manner known to those skilled in the art. Accordingly, the movable part 4 is accessible from below, that is, from the interior of the base cabinet. The kitchen furniture, so the base cabinet, is not shown.

Das als Gehäuse ausgebildete bewegliche Teil 4 mit den weiteren Komponenten ist in einem in der Fig. 5 dargestellten Betriebszustand des Kochfelds, also des Küchengeräts 2, mittels nicht dargestellter Montagemittel an dem Tragteil 3 derart fix montiert, dass das Küchengerät 2 betriebsbereit ist. Die Montagemittel sind hier als handelsübliche Schrauben mit Außengewinde ausgebildet, mittels der das bewegliche Teil 4 mit dem Tragteil 3 schraubverbunden ist. In dem Betriebszustand des Kochgeräts 2 verbinden die Schrauben das bewegliche Teil 4 mit dem Tragteil 3 an allen vier Seiten des Küchengeräts 2. In einem nicht dargestellten Wartungszustand des Küchengeräts 2 ist der Zugriff auf die in dem als Gehäuse ausgebildeten beweglichen Teil 4 angeordneten weiteren Komponenten des als Kochfelds ausgebildeten Küchengeräts 2 ermöglicht. Der Zugriff auf das Gehäuse, nämlich auf die in dem Gehäuse angeordneten weiteren Komponenten des Küchengeräts 2, ist beispielsweise bei einer Wartung und/oder bei einer Reparatur des Küchengeräts 2 durch einen Kundendienstmitarbeiter des Herstellers oder eines Fachhändlers erforderlich.The movable part 4 designed as a housing with the other components is in one in the Fig. 5 The operating state shown of the hob, that is to say of the kitchen appliance 2, is fixedly mounted on the support part 3 by means of mounting means (not shown) in such a way that the kitchen appliance 2 is ready for operation. The mounting means are designed here as commercially available screws with an external thread, by means of which the movable part 4 is screw-connected to the support part 3. In the operating state of the cooking appliance 2, the screws connect the movable part 4 to the support part 3 on all four sides of the kitchen appliance 2. In a maintenance state, not shown, of the kitchen appliance 2, access to the further components of the as a hob trained kitchen appliance 2 allows. Access to the housing, namely to the further components of the kitchen appliance 2 arranged in the housing, is required, for example, during maintenance and / or during a repair of the kitchen appliance 2 by a customer service representative of the manufacturer or a specialist dealer.

Hierfür wird das Küchengerät 2 von dessen in Fig. 5 dargestelltem Betriebszustand in dessen nicht dargestellten Wartungszustand überführt. Dies geschieht wie folgt:
Um das Küchengerät 2 von dessen Betriebszustand in dessen Wartungszustand zu überführen, löst beispielsweise der Kundendienstmitarbeiter zunächst die Schrauben des Küchengeräts 2. Die weitere Vorgehensweise sowie der weitere Aufbau des Küchengeräts 2 entspricht im Wesentlichen dem ersten Ausführungsbeispiel, so dass diesbezüglich auf die obigen Ausführungen zu dem ersten Ausführungsbeispiel verwiesen wird. Im Unterschied zu dem ersten Ausführungsbeispiel weist das Küchengerät 2 hier insgesamt zwei separate Haltemittel 6 auf, die im Bedarfsfall, also beispielsweise bei Kundendienstarbeiten, mit dem Tragteil 3 und dem beweglichen Teil 4 des Küchengeräts 2 verbunden werden können. In den Fig. 5 und 6 ist lediglich ein einziges der zwei Haltemittel 6 des vorliegenden Ausführungsbeispiels exemplarisch dargestellt. Die diesbezüglichen Ausführungen sind für das andere Haltemittel 6 ebenfalls gültig. Zum anderen ist das an dem jeweiligen Haltemittel 6 ausgebildete Verbindungsmittel 10 zur Verbindung des Haltemittels 6 mit dem Tragteil 3 im Unterschied zu dem ersten Ausführungsbeispiel ebenfalls als ein Formschlusskörper, nämlich als ein kugelförmiger Kloben, ausgebildet, der mit dem dazu korrespondierend ausgebildeten Verbindungsmittel 7 des Tragteils 3, nämlich einem Formschlusselement mit einer Schlüssellochgeometrie, zur Verbindung des Haltemittels 6 mit dem Tragteil 3 in dem Betriebszustand und in dem Wartungszustand des Küchengeräts 2 zusammenwirkt. Siehe hierzu die Fig. 6, in der eines der Haltemittel 6 sowie das Küchengerät 2 in dem Bereich dieses Haltemittels 6 in einer vergrößerten Darstellung gezeigt ist.For this purpose, the kitchen appliance 2 is of its in Fig. 5 The operating state shown is transferred to its maintenance state, not shown. This is done as follows:
In order to transfer the kitchen appliance 2 from its operating state to its maintenance state, the customer service representative, for example, first loosens the screws of the kitchen appliance 2. The further procedure and the further structure of the kitchen appliance 2 essentially corresponds to the first exemplary embodiment, so that in this regard the above remarks on the reference is made to the first embodiment. In contrast to the first exemplary embodiment, the kitchen appliance 2 here has a total of two separate holding means 6, which can be connected to the support part 3 and the movable part 4 of the kitchen appliance 2 if necessary, for example during customer service work. In the Fig. 5 and 6th only a single one of the two holding means 6 of the present exemplary embodiment is shown as an example. The relevant statements are also valid for the other holding means 6. On the other hand, the connecting means 10 formed on the respective holding means 6 for connecting the holding means 6 to the support part 3, in contrast to the first exemplary embodiment, is also designed as a form-fitting body, namely as a spherical clamp, which is connected to the correspondingly designed connecting means 7 of the support part 3, namely a form-fit element with a keyhole geometry, for connecting the holding means 6 to the support part 3 in the operating state and in the maintenance state of the kitchen appliance 2. See the Fig. 6 , in which one of the holding means 6 and the kitchen appliance 2 is shown in the area of this holding means 6 in an enlarged view.

Denkbar ist jedoch auch, dass das Verbindungsmittel des mindestens einen Haltemittels sowie das dazu korrespondierende Verbindungsmittel des Tragteils als zueinander korrespondierende Gewinde einer Schraubverbindung ausgebildet sind. Der Kundendienstmitarbeiter schraubt in diesem Fall das Haltemittel mittels dessen dem Tragteil zugeordneten und als Schraubbolzen ausgebildeten Verbindungsmittel in das als Innengewinde ausgebildete Verbindungsmittel des Tragteils ein, so dass das Haltemittel an dem Tragteil festgelegt ist. Anschließend hängt der Kundendienstmitarbeiter das Haltemittel mittels dessen dem beweglichen Teil zugeordneten und als Formschlusskörper ausgebildeten Verbindungsmittel in das diesem zugeordnete und als Formschlusselement des beweglichen Teils ausgebildete Verbindungsmittel ein. Das mindestens eine Haltemittel ist in diesem Fall also als ein separates Haltemittel ausgebildet. Danach löst der Kundendienstmitarbeiter bis auf die Schraubverbindung des Haltemittels mit dem Tragteil alle noch vorhandenen Schraubverbindungen, so dass das als Gehäuse ausgebildete bewegliche Teil mit den weiteren Komponenten aufgrund der Schwerkraft von dem Betriebszustand in den Wartungszustand überführt wird. Der Kundendienstmitarbeiter kann das bewegliche Teil beispielsweise auf einer Unterlage, einem Schrankboden oder dergleichen, ablegen. Der flexible Schaft des Haltemittels ist entsprechend lang gewählt. Um verschiedenen Einbausituationen gerecht zu werden, kann der Kundendienstmitarbeiter hierfür beispielsweise Haltemittel 6 mit voneinander verschiedenen Schaftlängen mitführen. Bei dem zweiten Ausführungsbeispiel kann das bewegliche Teil 4 relativ zu dem Tragteil 3 an der in der Bildebene von Fig. 5 links dargestellten Seite des Küchengeräts 2 in dessen Wartungslage abgesenkt werden, wobei das bewegliche Teil 4 an der in der Bildebene von Fig. 5 rechts dargestellten Seite des Küchengeräts 2 auf dem Fachmann bekannte Weise drehbar an dem Tragteil 3 festgelegt ist.However, it is also conceivable that the connecting means of the at least one holding means and the connecting means of the support part corresponding thereto are designed as mutually corresponding threads of a screw connection. In this case, the customer service employee screws the retaining means into the internal threading of the supporting part by means of its connecting means assigned to the supporting part and designed as screw bolts, so that the retaining means is fixed to the supporting part. The customer service employee then hooks the holding means into the connecting means assigned to it and designed as a form-locking element of the movable part by means of its connecting means assigned to the movable part and designed as a form-fit body. In this case, the at least one holding means is designed as a separate holding means. Then the customer service employee loosens all screw connections that are still present except for the screw connection of the holding means with the support part, so that the movable part, designed as a housing, with the other components is transferred from the operating state to the maintenance state due to gravity. The customer service employee can place the movable part on a mat, a cabinet floor or the like, for example. The flexible shaft of the holding means is selected to be correspondingly long. In order to cope with different installation situations, the customer service employee can, for example, carry holding means 6 with shaft lengths that are different from one another. In which In the second embodiment, the movable part 4 can be positioned relative to the support part 3 at the position in the image plane of FIG Fig. 5 The side of the kitchen appliance 2 shown on the left can be lowered into its maintenance position, the movable part 4 at the in the plane of the drawing Fig. 5 The side of the kitchen appliance 2 shown on the right is rotatably attached to the support part 3 in a manner known to those skilled in the art.

Ein drittes Ausführungsbeispiel eines erfindungsgemäßen Küchengeräts 2 ist in Fig. 7 teilweise dargestellt. Fig. 7 zeigt das Küchengerät 2 in dessen Wartungszustand, also mit in dessen Wartungslage befindlichem beweglichen Teil 4. Analog zu dem zweiten Ausführungsbeispiel ist auch das Küchengerät 2 gemäß dem dritten Ausführungsbeispiel als ein Einbaukochfeld ausgebildet. Entsprechend gelten die obigen Ausführungen zu dem zweiten Ausführungsbeispiel sowie die diesbezüglichen Rückverweise auf das erste Ausführungsbeispiel analog für das dritte Ausführungsbeispiel. Im Unterscheid zu dem zweiten Ausführungsbeispiel weist das dritte Ausführungsbeispiel an zwei einander gegenüberliegenden Seiten jeweils zwei Haltemittel 6 auf. Die insgesamt vier Haltemittel 6, von denen in Fig. 7 lediglich zwei zu sehen sind, weisen ferner jeweils ein als Schraubbolzen ausgebildetes Verbindungsmittel 10 auf, die mit den dazu korrespondierenden, jeweils als ein Innengewinde ausgebildeten, Verbindungsmitteln 7 des Tragteils 3 jeweils eine Schraubverbindung bilden. Anders als bei dem zweiten Ausführungsbeispiel ist das als Gehäuse ausgebildete bewegliche Teil 4 des Küchengeräts 2 hier sowohl in der Bildebene von Fig. 7 links wie auch in der Bildebene von Fig. 7 rechts absenkbar. Entsprechend ergibt sich eine gegenüber dem zweiten Ausführungsbeispiel verbesserte Zugänglichkeit des beweglichen Teils 4 und von beispielsweise an oder in dem beweglichen Teil 4 angeordneten, weiteren Komponenten des Küchengeräts 2.A third embodiment of a kitchen appliance 2 according to the invention is shown in FIG Fig. 7 partially shown. Fig. 7 shows the kitchen appliance 2 in its maintenance state, ie with the movable part 4 in its maintenance position. Analogously to the second exemplary embodiment, the kitchen appliance 2 according to the third exemplary embodiment is also designed as a built-in hob. The above statements regarding the second exemplary embodiment and the related back references to the first exemplary embodiment apply analogously to the third exemplary embodiment. In contrast to the second exemplary embodiment, the third exemplary embodiment has two holding means 6 on each of two opposite sides. The total of four holding means 6, of which in Fig. 7 only two can be seen, furthermore each have a connecting means 10 designed as a screw bolt, each of which forms a screw connection with the corresponding connecting means 7 of the support part 3, each designed as an internal thread. In contrast to the second exemplary embodiment, the movable part 4 of the kitchen appliance 2, which is designed as a housing, is here both in the image plane of FIG Fig. 7 left as well as in the image plane of Fig. 7 lowerable on the right. Correspondingly, compared to the second exemplary embodiment, there is improved accessibility of the movable part 4 and of further components of the kitchen appliance 2 arranged on or in the movable part 4, for example.

Somit ist für den Fachmann klar ersichtlich, dass je nach den Erfordernissen des Einzelfalls, beispielsweise in Abhängigkeit der Art des erfindungsgemäßen Küchengeräts und/oder in Abhängigkeit der jeweiligen Einbausituation des erfindungsgemäßen Küchengeräts, eine entsprechende Kombination zur Anwendung kommt. Entsprechend lassen sich für eine Vielzahl von voneinander verschiedenen Küchengeräten, beispielsweise sehr leichte Kochfelder bis sehr schwere Kochfelder, optimierte Ausführungsformen der Erfindung angeben.It is therefore clear to the person skilled in the art that a corresponding combination is used depending on the requirements of the individual case, for example depending on the type of kitchen appliance according to the invention and / or depending on the respective installation situation of the kitchen appliance according to the invention. Correspondingly, optimized embodiments of the invention can be specified for a large number of kitchen appliances that differ from one another, for example very light hobs to very heavy hobs.
