Definitions
- the invention relates to a cutlery cleaning device of the type specified in the preamble of claim 1.
- the cutlery is usually only placed in one copy at a time, ie a knife and possibly a fork and spoon. This applies to the private sector as well as to most restaurants, hotels and guest houses. However, it has been shown that this does not meet the needs of many people, particularly at breakfast, when honey, sausage, jam and the like are consecutively consumed, the order of course being arbitrary. So you are forced to spread sausage or cheese on the bread or rolls with the same knife on which the food residues of the previous spread, for example a nut-nougat cream, are still attached. It is not always possible to provide two or more knives for each person, because this often fails due to the number of cutlery available.
- a cutlery cleaning device is known from FR-A-883 044, which consists of a liquid-receiving container with a lid.
- the lid has two openings for inserting a knife and between the two openings there is a device for wiping off food particles.
- This cutlery cleaning device is simple in construction, but cold water is used because no measures have been taken to keep the water at a certain temperature or even to heat it.
- US-A-3,725,641 describes a liquid-filled container which is made of metal and is provided with an electrical heating device. The container is located in a pot-shaped plastic housing that is only accessible from the opening at the top, which makes assembly and repair work difficult. It is therefore the object of the invention to provide a cutlery cleaning device of the type mentioned, with which the cleaning effect is improved and which is designed to be more service-friendly.
- the invention is particularly characterized in that the cavity formed between the pot and the jacket has a heat-insulating effect. This annulus between The jacket and pot can also be filled with a heat-insulating material.
- the cutlery cleaning device according to the invention makes it possible for everyone at the table to easily free their cutlery, in particular knives, from food residues, in order to subsequently use the cutlery with another dish, preferably spread, without affecting the taste of the subsequently selected dish is influenced by remnants of the previous one.
- the appropriately designed opening in the lid makes it easy to insert a knife and immerse it in the liquid in the container. Without lingering in the liquid, the knife can be pulled out along the device for wiping off food particles and is thus already cleaned.
- the lid which contains the stripping device
- the type of attachment can be carried out, for example, by a frictional connection, by a thread, by a bayonet lock or in some other suitable way. It is important, however, that the lid not only lies loosely on the container, so that the lid is not lifted when the knife is stripped along the stripping device.
- the casing can have a radially inwardly directed collar with an annular groove arranged coaxially to the casing, into which the upper end of the pot is pressed.
- the pot can also be held in such a way that its upper edge lies on a radially inward projection of the jacket and rests with its base on supporting elements of the footplate.
- a rubber seal is used near the upper end of the pot or jacket to prevent water from the pot from getting into the annular space between the jacket and the pot.
- a preferred embodiment of the heating device is that it comprises at least one PTC resistor and the PTC resistor rests on the one hand on the bottom of the pot and on the other hand on a connecting plate and the latter is supported on the footplate by means of a spring element.
- This measure has several advantages, which can be seen in particular in the fact that PTC resistors act as self-regulating heating elements and the metallic pot and the connection plate simultaneously serve as electrical contacts for the PTC resistors. In this way, there is minimal construction effort and good functionality.
- the spring element ensures that a good contact of the contact surfaces is always guaranteed.
- a heating device in the form of an electrical heating spiral can also be provided, which surrounds part of the outer surface of the pot.
- Such heating coils have a large heating capacity, so that a rapid heating of the water in the pot is made possible. Since such heating coils generally have no self-regulating properties, it is advisable to provide a temperature controller.
- a switch is present, which is connected between the heating device and a connecting cable.
- the device for stripping food waste consists of wiper lips, which are arranged on both sides of slots.
- the wiper lips extend over the entire length of the slots and the width of the slot remaining between the wiper lips is less in the unactuated starting position than the thickness of the cutlery to be cleaned.
- An extremely low manufacturing effort for the wiper lips is achieved if the wiper lips are designed as thin-walled lips molded onto the cover and from its plastic material.
- the arrangement of the opening for inserting the cutlery and the slots with the wiping lips differs as required, it being possible to take into account how many people who are eating the same cutlery at one table are provided with such a cutlery cleaning device.
- a useful embodiment is that the opening for inserting the cutlery in the middle of the lid and the slots are arranged in a star shape starting from the opening.
- each slot is provided with a conical extension towards the opening and that the opening between two adjacent extensions is designed to be arcuate, the apex of the arc is directed into the opening.
- An alternative embodiment of the lid is that two openings are provided for introducing the cutlery and at least one slot is assigned to each opening. Such an arrangement is both in a round cutlery cleaning device or lid and in an elongated Shape possible. For space-saving division, the openings are diametrically opposite one another and the slots are arranged parallel to one another and in the opposite direction.
- a device for sharpening knife blades can be provided, by means of which the knife blade is sharpened simultaneously and without additional effort for the user each time the knife is cleaned.
- a device can expediently be designed such that a device for sharpening knife blades is arranged at the end of the slot remote from the opening, said device comprising at least one sharpening steel fastened in or on the material of the cover.
- the jacket 14 is releasably attached to the base plate 15 by pressing, screws, clips or in any other suitable way.
- An electric heating device is provided on the underside of a bottom 19 of the pot 13, which comprises several PTC resistors 20 connected in parallel.
- the PTC resistors lie on a connection plate 21 which is supported on the base plate 15 by means of a spring element 22.
- An electrical connection cable 23 is guided through the base plate 15 and each wire of the connection cable 23 is electrically conductively connected to the connection plate 21 and the pot 13. Since the PTC resistors 20 regulate the heating power themselves as a function of the temperature, additional regulators and switches as well as connecting lines are not required. Vent openings 24 are provided in the base plate 15.
- the upper end 13 * of the pot 13 is sealed by being pressed into the groove 16 in the bead 17, so that even when the pot 13 is overfilled or by inclining, no water enters the space between the pot 13 and the jacket 14 or foot part that accommodates the electric heating device 15 can reach.
- Other measures can also be provided for suitable sealing.
- a cover 10 is arranged, in which an opening 11 is provided, the shape of which will be discussed in more detail later.
- the lid 10 can be removed from the jacket 14, but it must sit on the jacket 14 in a friction or form-fitting manner, so that the lid 10 is not lifted off when the cutlery is cleaned.
- the pot 13 is filled with hot or heated water up to a certain height not far from the lid 10.
- the knife is inserted with its blade through an enlarged part of the opening 11 into the pot 13, then moved laterally between two scraper lips and then pulled upwards between the scraper lips 12, thereby removing food residues adhering to the blade.
- FIG. 3a and 3b show an enlarged view of the detail X in Fig. 1. From this view it can be seen that the lid 10 has an opening 11 which is formed at certain points to a narrow slot 25 which is parallel to itself this extending scraper lips 12 is limited.
- the scraper lips can be attached to the cover 10 as separately manufactured parts made of a rubber-elastic material, but the configuration as a thin-walled scraper lips formed on the cover material 10 from its plastic material is particularly advantageous, which thus arise during the production of the cover without an additional operation.
- FIG. 3a shows the wiper lips in their normal position
- FIG. 3b shows the wiper function of the wiper lips 12. Since the width of the slot 25 is less than the thickness of a knife blade 26, the wiper lips 12 bend upward in the drawing) in the direction in which the knife blade 26 is moved and, due to their good contact, graze on both sides of the knife blade 26 the adhering food residues. The direction of movement of the knife blade 26 is indicated by the arrow 27.
- FIG. 4 shows a top view of the cover 10, which has the opening 11 in its center, from which six slots 25 extend in a star shape.
- the slots 25 are provided on both sides with wiping lips 12.
- Each slot 25 is provided with a conical extension 28 towards the opening 11, the opening 11 being designed in an arc shape between two adjacent extensions 28. This arcuate design and the conical extensions 28 serve to facilitate the insertion of the knife blades into the slots 25.
- the line II-II shows the section in which the cover 10 is shown in FIG. 1.
- FIG. 5 shows the top view of another embodiment of the cover 10, which is particularly suitable for. Cutlery cleaning devices with a smaller diameter are suitable. There are two openings 29 in the cover 10, each of which is assigned a slot 25, the slots 25 - as already described for FIG. 1 - being equipped with wiper lips 12. The knife is cleaned in the manner described for FIG. 4.
- a cutlery cleaning device 1 which essentially consists of a metallic pot 30 and a base plate 31, a stepped housing shell 32 and a cover 33.
- Base plate 31, housing jacket 32 and cover 33 are made of plastic.
- the bottom of the pot 30 rests on support elements 34 of the base plate 31.
- the upper edge of the pot 30 lies on a radially inward projection 35 of the housing shell 32 and a rubber seal 36 is provided on the outer surface.
- the rubber seal 36 prevents water from entering a cavity 37 which is formed between the pot 30 and the housing shell 32.
- the housing jacket 32 has a step 32 in its lower area, so that the housing jacket 32 has a larger diameter and thus also a greater distance from the pot 30 in this area.
- a heating device 38 in the form of an electrical heating spiral, the ends of which are connected on the one hand to a connecting cable 39 and on the other hand to a switch 40.
- the lid 33 - like the lid 10 already described - has an opening for inserting the blade of a knife 42 and wiping lips 43 for removing the food residues from the blade 41.
- the handling for cleaning the knife 42 is the same as that already shown in FIG 1 has been described.
- Fig. 2 shows an enlarged view of a section of the cover 33 with a device for sharpening a knife blade.
- This device comprises a sharpening steel 44 embedded in the plastic material of the cover 33 and projecting into the slot 25.
- the knife 42 is pulled out, it is pulled along the sharpening steel 44 with the cutting edge and thus sharpened at the same time during each cleaning process.

Abstract
Description
Die Erfindung bezieht sich auf ein Besteckreinigungsgerät der im Oberbegriff des Patentanspruchs 1 angegebenen Gattung.The invention relates to a cutlery cleaning device of the type specified in the preamble of
Üblicherweise wird zu den Mahlzeiten - abgesehen von mehrgängigen Menüs - das Besteck nur in jeweils einem Exemplar aufgelegt, d. h. ein Messer und ggf. eine Gabel sowie Löffel. Dies gilt für den privaten Bereich genauso wie für die meisten Restaurants, Hotels und Pensionen. Es hat sich jedoch gezeigt, daß dies den Bedürfnissen vieler Menschen gerade beim Frühstück nicht gerecht wird, wenn aufeinanderfolgend Honig, Wurst, Marmelade und dergleichen verzehrt wird, wobei die Reihenfolge natürlich beliebig sein kann. Man ist also gezwungen, mit demselben Messer, an dem die Speisereste des vorhergehenden Brotaufstrichs, beispielsweise einer Nuß-Nougat-Creme, noch anhaften, Wurst oder Käse auf das Brot, bzw. Brötchen zu streichen. Nicht überall besteht die Möglichkeit, für jede Person zwei oder mehr Messer vorzusehen, da dies bereits in vielen Fällen an der Zahl des vorhandenen Bestecks scheitert.Apart from multi-course menus, the cutlery is usually only placed in one copy at a time, ie a knife and possibly a fork and spoon. This applies to the private sector as well as to most restaurants, hotels and guest houses. However, it has been shown that this does not meet the needs of many people, particularly at breakfast, when honey, sausage, jam and the like are consecutively consumed, the order of course being arbitrary. So you are forced to spread sausage or cheese on the bread or rolls with the same knife on which the food residues of the previous spread, for example a nut-nougat cream, are still attached. It is not always possible to provide two or more knives for each person, because this often fails due to the number of cutlery available.
Aus der FR-A- 883 044 ist ein Besteckreinigungsgerät bekannt, das aus einem eine Flüssigkeit aufnehmenden Behälter mit einem Deckel besteht. Der Deckel hat zwei Öffnungen zum Einführen eines Messers und zwischen den beiden Öffnungen befindet sich eine Einrichtung zum Abstreifen von Speiseresten. Dieses Besteckreinigungsgerät ist zwar einfach im Aufbau, es wird dabei jedoch kaltes Wasser benutzt, denn es sind keine Maßnahmen getroffen, das Wasser auf einer bestimmten Temperatur zu halten oder gar zu erwärmen.
In US-A- 3,725,641 ist ein mit Flüssigkeit gefüllter Behälter beschrieben, der aus Metall besteht und mit einer elektrischen Heizeinrichtung versehen ist. Der Behälter befindet sich in einem topfförmigen Kunststoffgehäuse, das ausschließlich von der Öffnung am oberen Rand zugänglich ist, was die Montage- und Reparaturarbeiten erschwert.
Es ist daher die Aufgabe der Erfindung, ein Besteckreinigungsgerät der genannten Art zu schaffen, mit dem die Reinigungswirkung verbessert wird und das servicegerechter gestaltet ist.A cutlery cleaning device is known from FR-A-883 044, which consists of a liquid-receiving container with a lid. The lid has two openings for inserting a knife and between the two openings there is a device for wiping off food particles. This cutlery cleaning device is simple in construction, but cold water is used because no measures have been taken to keep the water at a certain temperature or even to heat it.
US-A-3,725,641 describes a liquid-filled container which is made of metal and is provided with an electrical heating device. The container is located in a pot-shaped plastic housing that is only accessible from the opening at the top, which makes assembly and repair work difficult.
It is therefore the object of the invention to provide a cutlery cleaning device of the type mentioned, with which the cleaning effect is improved and which is designed to be more service-friendly.
Diese Aufgabe wird bei einem Besteckreinigungsgerät der gattungsgemäßen Art durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.
Die Erfindung zeichnet sich besonders dadurch aus, daß der zwischen Topf und Mantel gebildete Hohlraum wärmeisolierend wirkt. Dieser Ringraum zwischen Mantel und Topf kann zusätzlich mit einem wärmedämmenden Material gefüllt sein.
Das erfindungsgemäße Besteckreinigungsgerät ermöglicht es, daß am Tisch auf einfache Weise jede Person ihr Besteck, insbesondere Messer, von Speiseresten befreien kann, um anschließend das Besteck bei einer anderen Speise , vorzugsweise Brotaufstrich, zu benutzen, ohne daß eine Beeinflussung des Geschmacks der nachfolgend gewählten Speise durch Reste der vorherigen beeinflußt wird. Durch die entsprechend gestaltete Öffnung im Deckel ist problemlos das Einführen eines Messers und das Eintauchen in die Flüssigkeit des Behälters möglich. Ohne in der Flüssigkeit zu verweilen kann das Messer entlang der Einrichtung zum Abstreifen von Speiseresten herausgezogen werden und ist ist damit bereits gereinigt.This object is achieved in a cutlery cleaning device of the generic type by the characterizing features of
The invention is particularly characterized in that the cavity formed between the pot and the jacket has a heat-insulating effect. This annulus between The jacket and pot can also be filled with a heat-insulating material.
The cutlery cleaning device according to the invention makes it possible for everyone at the table to easily free their cutlery, in particular knives, from food residues, in order to subsequently use the cutlery with another dish, preferably spread, without affecting the taste of the subsequently selected dish is influenced by remnants of the previous one. The appropriately designed opening in the lid makes it easy to insert a knife and immerse it in the liquid in the container. Without lingering in the liquid, the knife can be pulled out along the device for wiping off food particles and is thus already cleaned.
Zur leichten Reinigung des Deckels, der die Abstreifeinrichtung beinhaltet, ist dieser lösbar auf dem Behälter befestigt. Die Art der Befestigung kann beispielsweise durch eine reibschlüssige Verbindung, durch ein Gewinde, durch einen Bajonettverschluß oder auf sonstige geeignete Weise erfolgen. Wichtig ist jedoch, daß der Deckel nicht nur lose auf dem Behälter aufliegt, damit beim Abstreifen des Messers entlang der Abstreifeinrichtung der Deckel nicht abgehoben wird.For easy cleaning of the lid, which contains the stripping device, it is detachably attached to the container. The type of attachment can be carried out, for example, by a frictional connection, by a thread, by a bayonet lock or in some other suitable way. It is important, however, that the lid not only lies loosely on the container, so that the lid is not lifted when the knife is stripped along the stripping device.
Um den Topf in dem Mantel zu befestigen und gleichzeitig derart abzudichten, daß kein Wasser aus dem Topf in den Ringraum gelangen kann, kann der Mantel einen radial nach innen gerichteten Bund mit einer koaxial zum Mantel angeordneten Ringnut aufweisen, in die das obere Ende des Topfes gepreßt ist. Die Halterung des Topfes kann aber auch so erfolgen, daß sein oberer Rand an einem radial nach innen gerichteten Vorsprung des Mantels liegt und mit seinem Boden auf Abstützelementen der Fußplatte ruht.In order to fasten the pot in the casing and at the same time to seal it in such a way that no water can get into the annular space from the pot, the casing can have a radially inwardly directed collar with an annular groove arranged coaxially to the casing, into which the upper end of the pot is pressed. The pot can also be held in such a way that its upper edge lies on a radially inward projection of the jacket and rests with its base on supporting elements of the footplate.
Damit kein Wasser aus dem Topf in den Ringraum zwischen Mantel und Topf gelangen kann, ist nahe dem oberen Ende des Topfes bzw. Mantels eine Gummidichtung eingesetzt.A rubber seal is used near the upper end of the pot or jacket to prevent water from the pot from getting into the annular space between the jacket and the pot.
Eine bevorzugte Ausgestaltung der Heizeinrichtung besteht darin, daß sie mindestens einen PTC-Widerstand umfaßt und der PTC-Widerstand einerseits am Boden des Topfes und andererseits an einer Anschlußplatte anliegt und letztere mittels eines Federelementes auf der Fußplatte abgestützt ist. Diese Maßnahme hat mehrere Vorzüge, die insbesondere darin zu sehen sind, daß PTC-Widerstände als selbstregulierende Heizelemente wirken und der metallische Topf und die Anschlußplatte gleichzeitig als elektrische Kontakte für die PTC-Widerstände dienen. Auf diese Weise ist ein minimaler baulicher Aufwand und gute Funktionsfähigkeit gegeben. Das Federelement sorgt dafür, daß stets eine gute Anlage der Kontaktflächen gewährleistet ist.A preferred embodiment of the heating device is that it comprises at least one PTC resistor and the PTC resistor rests on the one hand on the bottom of the pot and on the other hand on a connecting plate and the latter is supported on the footplate by means of a spring element. This measure has several advantages, which can be seen in particular in the fact that PTC resistors act as self-regulating heating elements and the metallic pot and the connection plate simultaneously serve as electrical contacts for the PTC resistors. In this way, there is minimal construction effort and good functionality. The spring element ensures that a good contact of the contact surfaces is always guaranteed.
Alternativ zu der Beheizung mittels PTC-Widerständen kann auch eine Heizeinrichtung in Form einer elektrischen Heizspirale vorgesehen sein, die einen Teil der Mantelfläche des Topfes umgibt. Derartige Heizspiralen haben eine große Heizleistung, so daß eine rasche Aufheizung des Wassers in dem Topf ermöglicht wird. Da derartige Heizspiralen in der Regel keine selbstregelnden Eigenschaften besitzen, ist es zweckmäßig, einen Temperaturregler vorzusehen. Darüber hinaus ist es von Vorteil, daß ein Schalter vorhanden ist, der zwischen die Heizeinrichtung und ein Anschlußkabel geschaltet ist.As an alternative to heating by means of PTC resistors, a heating device in the form of an electrical heating spiral can also be provided, which surrounds part of the outer surface of the pot. Such heating coils have a large heating capacity, so that a rapid heating of the water in the pot is made possible. Since such heating coils generally have no self-regulating properties, it is advisable to provide a temperature controller. In addition, it is advantageous that a switch is present, which is connected between the heating device and a connecting cable.
Damit beide Seiten eines Bestecks, bzw. der Klinge eines Messers gleichzeitig gereinigt werden können, wird vorgeschlagen, daß die Einrichtung zum Abstreifen von Speiseresten aus Abstreiflippen besteht, die jeweils zu beiden Seiten von Schlitzen angeordnet sind. Um eine sichere Funktion der Abstreiflippen und eine gute Reinigung des Bestecks zu erreichen, erstrecken sich die Abstreiflippen über die gesamte Länge der Schlitze und die Breite des zwischen den Abstreiflippen verbleibenden Schlitzes ist in der unbetätigten Ausgangslage geringer als die Dicke des zu reinigenden Bestecks. Ein äußerst geringer Herstellungsaufwand für die Abstreiflippen ist dann erreicht, wenn die Abstreiflippen als an dem Deckel und aus dessen Kunststoffmaterial angeformte, dünnwandige Lippen ausgebildet sind.So that both sides of a cutlery, or the blade of a knife can be cleaned at the same time, it is proposed that the device for stripping food waste consists of wiper lips, which are arranged on both sides of slots. In order to achieve a safe function of the wiper lips and a good cleaning of the cutlery, the wiper lips extend over the entire length of the slots and the width of the slot remaining between the wiper lips is less in the unactuated starting position than the thickness of the cutlery to be cleaned. An extremely low manufacturing effort for the wiper lips is achieved if the wiper lips are designed as thin-walled lips molded onto the cover and from its plastic material.
Die Anordnung der Öffnung zum Einführen des Bestecks sowie der Schlitze mit den Abstreiflippen ist je nach Bedarf unterschiedlich, wobei berücksichtigt werden kann, für wieviel Personen, die gleichzeitig an einem Tisch die Mahlzeit einnehmen, ein solches Besteckreinigungsgerät vorgesehen ist. Eine zweckmäßige Ausgestaltung besteht darin, daß die Öffnung zum Einführen des Bestecks in der Mitte des Deckels und die Schlitze von der Öffnung ausgehend sternförmig angeordnet sind. Zur Erleichterung der Einführung des Messers von der Mitte der Öffnung durch eine seitliche Bewegung in die Schlitze ist es vorteilhaft, daß jeder Schlitz zur Öffnung hin mit einer konischen Erweiterung versehen ist und zwischen zwei benachbarten Erweiterungen die Öffnung bogenförmig gestaltet ist, wobei der Scheitelpunkt des Bogens in die Öffnung hinein gerichtet ist.The arrangement of the opening for inserting the cutlery and the slots with the wiping lips differs as required, it being possible to take into account how many people who are eating the same cutlery at one table are provided with such a cutlery cleaning device. A useful embodiment is that the opening for inserting the cutlery in the middle of the lid and the slots are arranged in a star shape starting from the opening. In order to facilitate the insertion of the knife from the center of the opening by a lateral movement into the slots, it is advantageous that each slot is provided with a conical extension towards the opening and that the opening between two adjacent extensions is designed to be arcuate, the apex of the arc is directed into the opening.
Eine alternative Ausgestaltung des Deckels besteht darin, daß zwei Öffnungen zum Einführen des Bestecks vorgesehen sind und jeder Öffnung mindestens ein Schlitz zugeordnet ist. Eine solche Anordnung ist sowohl bei einem runden Besteckreinigungsgerät bzw. Deckel als auch in länglicher Form möglich. Zur raumsparenden Aufteilung sind dabei die Öffnungen diametral gegenüberliegend und die Schlitze parallel zueinander und in entgegengesetzter Richtung verlaufend angeordnet.An alternative embodiment of the lid is that two openings are provided for introducing the cutlery and at least one slot is assigned to each opening. Such an arrangement is both in a round cutlery cleaning device or lid and in an elongated Shape possible. For space-saving division, the openings are diametrically opposite one another and the slots are arranged parallel to one another and in the opposite direction.
In weiterer Ausgestaltung des Erfindungsgegenstandes kann eine Einrichtung zum Schärfen von Messerklingen vorgesehen sein, durch die bei jeder Reinigung des Messers gleichzeitig und ohne zusätzlichen Aufwand für den Benutzer die Messerklinge geschärft wird. Eine solche Einrichtung kann zweckmäßigerweise so gestaltet sein, daß an dem der Öffnung entfernt liegenden Ende des Schlitzes eine Einrichtung zum Schärfen von Messerklingen angeordnet ist, die mindestens einen im bzw. am Material des Deckels befestigten Wetzstahl umfaßt.In a further embodiment of the subject matter of the invention, a device for sharpening knife blades can be provided, by means of which the knife blade is sharpened simultaneously and without additional effort for the user each time the knife is cleaned. Such a device can expediently be designed such that a device for sharpening knife blades is arranged at the end of the slot remote from the opening, said device comprising at least one sharpening steel fastened in or on the material of the cover.

Der Mantel 14 ist auf der Fußplatte 15 mittels Einpressen, Schrauben, Klammern oder auf sonstige geeignete Weise lösbar befestigt. An der Unterseite eines Bodens 19 des Topfes 13 ist eine elektrische Heizvorrichtung vorgesehen, die mehrere, parallel geschaltete PTC-Widerstände 20 umfaßt. Die PTC-Widerstände liegen andererseits auf einer Anschlußplatte 21, die mittels eines Federelementes 22 auf der Fußplatte 15 abgestützt ist. Ein elektrisches Anschlußkabel 23 ist durch die Fußplatte 15 geführt und jeweils eine Ader des Anschlußkabels 23 ist mit der Anschlußplatte 21 und dem Topf 13 elektrisch leitend verbunden. Da die PTC-Widerstände 20 in Abhängigkeit der Temperatur die Heizleistung selbst regeln, sind zusätzliche Regler und Schalter sowie Verbindungsleitungen nicht erforderlich. In der Fußplatte 15 sind Entlüftungsöffnungen 24 vorgesehen.The
Das obere Ende 13* des Topfes 13 ist durch das Einpressen in die Nut 16 im Wulst 17 abgedichtet, so daß auch beim Überfüllen des Topfes 13 oder durch Neigen kein Wasser in den die elektrische Heizeinrichtung aufnehmenden Raum zwischen Topf 13 und Mantel 14 bzw. Fußteil 15 gelangen kann. Zur geeigneten Abdichtung können auch andere Maßnahmen vorgesehen sein.The
Am oberen Ende des Mantels 14 ist ein Deckel 10 angeordnet, in dem eine Öffnung 11 vorgesehen ist, auf deren Form später noch näher eingegangen wird. Der Deckel 10 ist vom Mantel 14 abnehmbar, er muß jedoch reib- oder formschlüssig auf dem Mantel 14 sitzen, damit beim Reinigen des Bestecks der Deckel 10 nicht abgehoben wird.At the upper end of the
Zum Reinigen eines Bestecks, beispielsweise eines - in Fig.1 nicht dargestellten - Messers, ist der Topf 13 bis zu einer bestimmten Höhe unweit des Deckels 10 mit heißem oder erwärmtem Wasser gefüllt. Das Messer wird mit seiner Klinge durch einen erweiterten Teil der Öffnung 11 in den Topf 13 eingeführt, dann seitlich zwischen zwei Abstreiflippen bewegt und anschließend zwischen den Abstreiflippen 12 nach oben gezogen, wodurch an der Klinge anhaftende Essensreste entfernt werden.To clean a cutlery, for example a knife (not shown in FIG. 1), the
Fig. 3a und 3b zeigen eine vergrößerte Darstellung der Einzelheit X in Fig. 1. Aus dieser Ansicht ist zu ersehen, daß der Deckel 10 eine Öffnung 11 besitzt, die an bestimmten Stellen zu einem schmalen Schlitz 25 geformt ist, der von sich parallel zu diesem erstreckenden Abstreiflippen 12 begrenzt ist. Die Abstreiflippen können als separat gefertigte Teile aus einem gummielastischen Material an dem Deckel 10 befestigt sein, besonders vorteilhaft ist aber die Ausgestaltung als an dem Deckel 10 aus dessen Kunststoffmaterial angeformte, dünnwandige Abstreiflippen, die somit bei der Herstellung des Deckels ohne zusätzlichen Arbeitsgang entstehen.3a and 3b show an enlarged view of the detail X in Fig. 1.

Während Fig. 3a die Abstreiflippen in ihrer Normalstellung zeigt, ist in Fig. 3b die Abstreiffunktion der Abstreiflippen 12 dargestellt. Da die Breite des Schlitzes 25 geringer ist als die Dicke einer Messerklinge 26, biegen sich die Abstreiflippen 12 in der Zeichnung gesehen nach oben ) in die Richtung, in der die Messerklinge 26 bewegt wird und streifen aufgrund ihrer guten Anlage zu beiden Seiten der Messerklinge 26 die anhaftenden Speisereste ab. Mit dem Pfeil 27 ist die Bewegungsrichtung der Messerklinge 26 angegeben.3a shows the wiper lips in their normal position, FIG. 3b shows the wiper function of the
Fig. 4 zeigt eine Draufsicht auf den Deckel 10, der in seiner Mitte die Öffnung 11 aufweist, von der ausgehend sich sternförmig sechs Schlitze 25 erstrecken. Die Schlitze 25 sind jeweils zu beiden Seiten mit Abstreiflippen 12 versehen.
