Description

Die Erfindung bezieht sich auf eine Reinigungsvorrichtung für den Scherkopf eines Trockenrasierapparates, mit einem Gehäuse, das eine Aufnahme zum Einsetzen des Scherkopfs des Trockenrasierapparates, einen Behälter zur Aufnahme von Reinigungsflüssigkeit und eine Pumpe aufweist, durch die über eine Zuführleitung Reinigungsflüssigkeit aus dem Behälter in die Aufnahme förderbar ist.The invention relates to a cleaning device for the shaving head of a dry shaver, comprising a housing having a receptacle for inserting the shaving head of the dry shaver, a container for receiving cleaning liquid and a pump through which a supply line cleaning liquid from the container into the receptacle is eligible.

Eine derartige Reinigungsvorrichtung ist aus der DE 44 02 237 C1 bekannt. Der Trockenrasierapparat wird hierzu senkrecht mit seinem Scherkopf nach unten in die Aufnahme eingesetzt. Die Aufnahme ist mit ihrer wannenförmigen Ausbildung an die Kontur des Scherkopfes angepaßt und nimmt diesen vollständig in sich auf. Die Aufnahme besitzt eine Auslaßöffnung und einen Überlauf, die in einen Auffangbehälter münden. Über eine Leitung ist der Auffangbehälter mit dem Behälter für die Reinigungsflüssigkeit verbunden.Such a cleaning device is known from DE 44 02 237 C1 known. For this purpose, the dry shaver is inserted vertically with its shaving head down into the receptacle. The recording is adapted with its trough-shaped design to the contour of the shaving head and takes this completely in itself. The receptacle has an outlet opening and an overflow, which open into a collecting container. Via a line of the collecting container is connected to the container for the cleaning liquid.

Mit dem Beginn des Reinigungsvorgangs wird mit der Pumpe die Reinigungsflüssigkeit aus dem Behälter in die Aufnahme gefördert, so daß sich der Scherkopf vollständig in der Reinigungsflüssigkeit befindet. Die Auslaßöffnung und die Fördermenge sind derart aufeinander abgestimmt, daß die Reinigungsflüssigkeit sowohl über die Auslaßöffnung als auch über den Überlauf in den Auffangbehälter abfließt. Auf diese Weise wird die Aufnahme während des Reinigungsvorgangs kontinuierlich mit Reinigungsflüssigkeit durchspült. Der Überlauf dient zudem als Sicherheitsvorrichtung, damit die Reinigungsflüssigkeit ein bestimmtes Niveau in der Aufnahme nicht übersteigt. Die Nachteile dieser Reinigungsvorrichtung bestehen darin, daß mit der ständigen Durchspülung der als Bad ausgebildeten Aufnahme ein gewisser Verbrauch an Reinigungsflüssigkeit auftritt. Außerdem werden durch das ständige Umwälzen der Reinigungsflüssigkeit immer wieder Haarreste und Beläge, die sich bereits im Behälter abgelagert haben, aufgewirbelt, wodurch der Filter stark belastet wird. In einigen Fällen ist die Reinigungswirkung der Reinigungsvorrichtung dann nicht optimal. Insbesondere, wenn im Anschluß an den Gebrauch des Trockenrasierapparates der Scherkopf nicht sofort gereinigt wird, können am Scherkopf vorhandene Reste von Haut- und Haarteilen in Verbindung mit Hautfett, Schweiß und/oder Hautcreme eintrocknen und fest haftende Beläge bilden. Weder die Strömung der Reinigungsflüssigkeit in der Aufnahme noch die zusätzliche Bewegung des Scherkopfes sind dann in Extremfällen ausreichend, um diese fest anhaftenden Beläge in kurzer Zeit lösen zu können. Dies hat zur Folge, daß der Reinigungsprozeß sehr lange dauert, um eine zufriedenstellende Reinigung des Scherkopfes zu erzielen. Die langen Laufzeiten der vom Motor angetriebenen Fördervorrichtung und des Trockenrasierapparates führen zu einer nicht unerheblichen Geräuschentwicklung, die vom Benutzer der Reinigungsvorrichtung als störend empfunden wird. Die Fördereinrichtung benötigt überdies eine relativ große Förderleistung, um die Aufnahme während des Reinigungsvorgangs immer gefüllt zu halten, da die Reinigungsflüssigkeit durch die Auslaßöffnung und den Überlauf abfließt. Dies führt wegen der hohen Drehzahl des Motors ebenfalls zu einer unerwünschten Geräuschbelastung. Des weiteren können gegebenenfalls verschiedene Bestandteile der Reinigungsflüssigkeit, z.B. Alkohol, bei langen Reinigungsprozessen Bauteile des Trockenrasierapparates oberflächenmäßig angreifen, so daß die Auswahl entsprechender Materialien und aufgebrachter Oberflächen eingeschränkt ist.With the beginning of the cleaning process, the cleaning liquid is conveyed from the container into the receptacle with the pump, so that the shaving head is completely in the cleaning liquid. The outlet and the flow rate are coordinated so that the cleaning fluid flows both through the outlet opening and over the overflow into the collecting container. In this way, the recording is continuously flushed with cleaning fluid during the cleaning process. The overflow also serves as a safety device, so that the cleaning fluid does not exceed a certain level in the recording. The disadvantages of this cleaning device are that a certain consumption of cleaning liquid occurs with the constant flushing of the bath formed as a recording. In addition, by the constant circulation of the cleaning liquid again and again hair residues and deposits, which have already deposited in the container, swirled, whereby the filter is heavily loaded. In some cases, the cleaning effect of the cleaning device is then not optimal. In particular, if, following the use of the dry shaver, the shaving head is not immediately cleaned, residues of skin and hair parts present on the shaving head can dry in conjunction with skin fat, sweat and / or skin cream and form firmly adhering coverings. Neither the flow of the cleaning liquid in the recording nor the additional movement of the shaving head are then sufficient in extreme cases to solve these firmly adhering coatings in a short time. This has the consequence that the cleaning process takes a long time to achieve a satisfactory cleaning of the shaving head. The long running times of the motor-driven conveyor and the dry shaver lead to a considerable noise, which is perceived by the user of the cleaning device as disturbing. The conveyor also requires a relatively large flow rate to keep the recording during the cleaning process always filled, since the cleaning fluid flows through the outlet opening and the overflow. This leads due to the high speed of the engine also to an undesirable noise level. Furthermore, if necessary, various components of the cleaning liquid, for example alcohol, can attack the surface of the components of the dry shaver during long cleaning processes, so that the selection of corresponding materials and applied surfaces is restricted.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Reinigungsvorrichtung der eingangs genannten Art zu schaffen, die eine optimale Reinigungswirkung bei einem möglichst geringen Umlauf an Reinigungsflüssigkeit benötigt. Weiterhin soll die Reinigungsvorrichtung eine geringe Geräuschentwicklung aufweisen und sich durch einen einfachen Aufbau auszeichnen.The present invention is therefore an object of the invention to provide a cleaning device of the type mentioned, which requires an optimal cleaning effect at the lowest possible circulation of cleaning fluid. Furthermore, the cleaning device should have a low noise and be characterized by a simple structure.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Aufnahme wannenförmig zum annähernd horizontalen Einsetzen des Trockenrasierapparates ausgebildet ist und an seinem einen Ende in einen Aufnahmebereich übergeht, in den der Scherkopf einsetzbar ist, wobei die Zuführleitung auf die Oberseite des eingesetzten Scherkopfs gerichtet in den Aufnahmebereich mündet und eine Rücklaufleitung vom Boden des Aufnahmebereichs zum Behälter führt.This object is achieved in that the receptacle is formed trough-shaped for approximately horizontal insertion of the dry shaving and merges at one end into a receiving area in which the shaving head is used, the supply line opens directed to the top of the shaving head used in the receiving area and a return line from the bottom of the receiving area leads to the container.

Bedingt durch die horizontale Aufnahme des Trockenrasierapparates erfolgt die Reinigung des Scherkopfes nicht mehr in einem Bad, sondern durch die in den Aufnahmebereich eingesprühte Reinigungsflüssigkeit. Der Vorteil einer derartigen Reinigungsvorrichtung besteht darin, daß durch das Aufsprühen der Reinigungsflüssigkeit das Ablösen der Haarreste und Beläge verbessert wird. Infolge der Bewegung der Scherteile im Scherkopf während der Reinigung, wird die Reinigungsflüssigkeit in den Scherkopf gesaugt, so daß eine gleichmäßige Verteilung der Reinigungsflüssigkeit und Benetzung der Scherteile gewährleistet ist. Darüber hinaus wird der dabei entstehende Perlator-Effekt für die Reinigung genutzt. Beim Aufsprühen trifft die Reinigungsflüssigkeit in Form kleiner Tropfen auf den Scherkopf auf. Nach dem Passieren der Scherfolie gelangen die Tropfen auf die sich bewegenden Scherteile. Beim Auftreffen der Tropfen auf die Scherteile werden die Tropfen weiter zerteilt, wobei sie sich unter Blasenbildung mit Luft mischen. Die beim Platzen der Blasen freiwerdende Schallenergie unterstützt das Ablösen von Belägen und Haarresten. Die Reinigungswirkung der Tropfen ist größer als die eines Flüssigkeitsstrahls oder eines Bades.Due to the horizontal recording of the dry shaver cleaning the shaving head is no longer done in a bath, but by the sprayed into the receiving area cleaning liquid. The advantage of such a cleaning device is that the detachment of the hair residues and deposits is improved by spraying the cleaning liquid. As a result of the movement of the shaving parts in the shaving head during cleaning, the cleaning liquid is sucked into the shaving head, so that a uniform distribution of the cleaning liquid and wetting of the shearing parts is ensured. In addition, the resulting pearling effect is used for cleaning. During spraying, the cleaning liquid hits the shaving head in the form of small drops. After passing through the shaving foil, the drops reach the moving shearing parts. Upon impact of the drops on the shearing parts, the drops are further divided, blending with air and mixing. The released when bursting the bubbles Sound energy supports the detachment of coverings and hair residues. The cleaning effect of the drops is greater than that of a jet of liquid or a bath.

Die erfindungsgemäße Reinigungsvorrichtung benötigt aufgrund der aufgesprühten Reinigungsflüssigkeit bedeutend weniger Reinigungsflüssigkeit für den Reinigungsprozeß. Die Pumpe kann daher mit einer geringeren Drehzahl laufen, was zu einer Geräuschminderung führt.The cleaning device according to the invention requires significantly less cleaning liquid for the cleaning process due to the sprayed-on cleaning liquid. The pump can therefore run at a lower speed, which leads to a reduction in noise.

Zur optimalen Ausnutzung der aufgesprühten Reinigungsflüssigkeit mündet die Zuführleitung in den oberen Bereich des Aufnahmebereichs.For optimal utilization of the sprayed-on cleaning liquid, the supply line opens into the upper region of the receiving area.

Damit in die Aufnahme gelangende Reinigungsflüssigkeit abfließen kann, erstreckt sich die Aufnahme in einem Winkel zur Horizontalen von etwa 0° bis 20 °, vorzugsweise von 3° bis 15° und insbesondere von 5° geneigt zum Aufnahmebereich hin.In order to allow cleaning fluid to flow into the receptacle, the receptacle extends at an angle to the horizontal of approximately 0 ° to 20 °, preferably of 3 ° to 15 ° and in particular of 5 ° inclined to the receiving area.

Das Aufsprühen der Reinigungsflüssigkeit auf den Scherkopf gestaltet sich besonders einfach, wenn die Zuführleitung über eine Düse in den Aufnahmebereich mündet. Durch eine geeignete Wahl der Düsenform lassen sich verschiedene Strahlmuster erzeugen. Eine feine Verteilung der Reinigungsflüssigkeit über eine große Oberfläche läßt sich mit einer Flachstrahldüse erreichen. Der Vorteil von Flachstrahldüsen besteht darin, daß infolge des Auffächerns des Flüssigkeitsstrahls bereits aus einer kurzen Entfernung ein großer Bereich des Scherkopfes mit Reinigungsflüssigkeit beaufschlagt werden kann. Die Flachstrahldüsen können daher relativ nah am Scherkopf angeordnet sein, wodurch der Aufnahmebereich klein gehalten werden kann. Unter Umständen kann die Verwendung einer Flachstrahldüse zum Aufsprühen von Reinigungsflüssigkeit ausreichend sein. Die erfindungsgemäße Reinigungsvorrichtung gestaltet sich dadurch besonders kostengünstig.The spraying of the cleaning liquid on the shaving head is particularly simple when the supply line opens through a nozzle in the receiving area. By a suitable choice of the nozzle shape, different jet patterns can be generated. A fine distribution of the cleaning liquid over a large surface can be achieved with a flat jet nozzle. The advantage of flat jet nozzles is that due to the fanning of the liquid jet already a short distance from a large area of the shaving head can be acted upon with cleaning liquid. The flat jet nozzles can therefore be arranged relatively close to the shaving head, whereby the receiving area can be kept small. Under certain circumstances, the use of a flat jet nozzle for spraying cleaning fluid may be sufficient. The cleaning device according to the invention is characterized particularly cost effective.

In einer weiteren Ausgestaltung kommen Punktstrahldüsen zum Einsatz. Aufgrund ihrer Strahlgeometrie ist der mit Reinigungsflüssigkeit beaufschlagte Bereich klein, wenn der Abstand zwischen Düse und Scherkopf gering ist. Dennoch ist die Verwendung von Punktstrahldüsen sinnvoll, da durch die sich bewegenden Scherteile die Reinigungsflüssigkeit in den Scherkopf gesaugt und dort verteilt wird. Durch gezielte Anordnung und Ausrichtung von zwei oder mehr Düsen läßt sich ohne größeren Aufwand die gesamte Oberfläche des Scherkopfes mit Reinigungsflüssigkeit beaufschlagen. Der Vorteil von Punktstrahldüsen ist ihr einfacher Aufbau.In a further embodiment, spot jet nozzles are used. Due to its jet geometry, the area treated with cleaning fluid is small when the distance between the nozzle and shaving head is small. Nevertheless, the use of spot jet nozzles makes sense, as the cleaning liquid is sucked into the shaving head and distributed there by the moving shearing parts. By targeted arrangement and alignment of two or more nozzles can be applied without much effort, the entire surface of the shaving head with cleaning liquid. The advantage of spot jet nozzles is their simple construction.

Um das Austreten von Reinigungsflüssigkeit infolge der horizontalen Anordnung des Trockenrasierapparates zu verhindern, ist die Öffnung des Aufnahmebereichs an die Kontur des Trockenrasierapparates, insbesondere des Scherkopfes angepaßt. Aufgrund der engen Passung muß der Trockenrasierapparat exakt in die Aufnahme eingesetzt werden. Diese Handhabung läßt sich erleichtern, wenn am Übergang der Aufnahme in den Aufnahmebereich eine Dichtmanschette angeordnet ist, durch die der eingesetzte Trockenrasierapparat umschließbar ist. Aufgrund der flexibel gestalteten Dichtung gestaltet sich das Einsetzen und Entnehmen des Trockenrasierapparates bei gleicher Dichtwirkung wesentlich leichter. Gleichzeitig wird das Benetzen anderer Bereiche des Trockenrasierapparates zuverlässig verhindert.In order to prevent the escape of cleaning fluid due to the horizontal arrangement of the dry shaver, the opening of the receiving area is adapted to the contour of the dry shaver, in particular the shaving head. Due to the tight fit of the dry shaver must be used exactly in the recording. This handling can be facilitated if at the transition of the recording in the receiving area a sealing sleeve is arranged, through which the dry shaver used is umschließbar. Due to the flexibly designed seal, the insertion and removal of the dry shaver designed with the same sealing effect much easier. At the same time, the wetting of other areas of the dry shaver is reliably prevented.

Dennoch kann es beim unsachgemäßen Einsetzen des Trockenrasierapparates oder bei leichten Beschädigungen der Dichtmanschette zum Austritt von Reinigungsflüssigkeit kommen. Führt von dem Bodenbereich der Aufnahme ein Bypass zur Rücklaufleitung zu dem Behälter für die Reinigungsflüssigkeit, gestattet dies das Rückführen der ausgetretenen Reinigungsflüssigkeit in den Behälter. In vorteilhafter Weise mündet der Bypass nahe der Dichtmanschette in den Bodenbereich der Aufnahme und verläuft vorteilhafterweise im wesentlichen parallel zu der Rücklaufleitung, wobei Bypass und Rücklaufleitung ein gemeinsames Bauteil bilden können.Nevertheless, improper insertion of the dry shaver or slight damage to the sealing sleeve can lead to leakage of cleaning fluid. If a bypass leads from the bottom region of the intake to the return line to the container for the cleaning fluid, this allows the return of the leaked cleaning fluid into the container. Advantageously, the bypass opens near the sealing sleeve in the bottom region of the receptacle and advantageously extends substantially parallel to the return line, wherein the bypass and return line can form a common component.

Die aus dem Scherkopf gelösten Haarreste und Belege werden durch die Reinigungsflüssigkeit in den Behälter transportiert. Um die Reinigungsflüssigkeit mehrmals für den Reinigungsprozeß nutzen zu können, müssen die abtransportierten Partikel von der Reinigungsflüssigkeit getrennt werden. Diese Trennung erfolgt vorteilhafterweise in einem Filter oder direkt im Behälter für die Reinigungsflüssigkeit. Durch gezieltes Führen der Reinigungsflüssigkeit zum Boden des Behälters wird das Ablagern der abtransportierten Partikel ermöglicht.The hair remainders and documents released from the shaving head are transported by the cleaning liquid into the container. In order to use the cleaning liquid several times for the cleaning process, the transported away particles must be separated from the cleaning liquid. This separation is advantageously carried out in a filter or directly in the container for the cleaning liquid. By targeted guiding the cleaning liquid to the bottom of the container, the deposition of the transported particles is made possible.

Die Ablagerung der Partikel läßt sich weiter erhöhen, wenn der Behälter eine das Ablagern fördernde Struktur aufweist. Dazu ist im Behälter eine stufenförmige Kaskade topfförmiger Aufnahmebehälter vorgesehen, deren oberster Aufnahmebehälter unterhalb der in den Behälter einmündenden Rücklaufleitung angeordnet ist. Die in den Behälter zurückfließende Reinigungsflüssigkeit wird über die einzelnen Aufnahmebehälter der Kaskade geleitet. Die in der Flüssigkeit mitgeführten Partikel können sich in den einzelnen Aufnahmebehältern absetzen, so daß am Ende der Kaskade die Reinigungsflüssigkeit mit wesentlich weniger Partikeln belastet ist. Somit steht für den nächsten Reinigungsvorgang eine durch Partikel nahezu unbelastete Reinigungsflüssigkeit mit einer dementsprechend größeren Reinigungswirkung zur Verfügung. Gleichzeitig wird dadurch der Einsatz eines kleineren Filters ermöglicht.The deposition of the particles can be further increased if the container has a deposition promoting structure. For this purpose, a step-shaped cascade cup-shaped receptacle is provided in the container, the uppermost receptacle is arranged below the opening into the container return line. The cleaning liquid flowing back into the container is passed through the individual receptacles of the cascade. The entrained in the liquid particles can settle in the individual receptacles, so that at the end of the cascade, the cleaning liquid is loaded with significantly fewer particles. Thus, for the next cleaning process, one is almost due to particles unloaded cleaning fluid with a correspondingly greater cleaning effect available. At the same time this allows the use of a smaller filter.

Zur einfachen Reinigung des Behälters kann dieser ein separates, in eine Ausnehmung des Gehäuses einsetzbares Bauteil sein.For easy cleaning of the container, this can be a separate, insertable into a recess of the housing component.

Die Entnahme von Reinigungsflüssigkeit aus dem Behälter läßt sich verbessern, wenn der Behälter eine tiefste Stelle besitzt, in der sich die Reinigungsflüssigkeit sammelt. Die Anordnung des Entnahmestutzens für die Zuführleitung in diesem Bereich gewährleistet die effektive Ausnutzung der Reinigungsflüssigkeit, insbesondere bei einem geringen Füllstand im Behälter. Auf eine komplizierte Ausgestaltung des Behälters kann dabei verzichtet werden, wenn der Boden des Behälters ein zur Entnahmestelle hin geneigtes Gefälle aufweist.The removal of cleaning liquid from the container can be improved if the container has a lowest point in which collects the cleaning liquid. The arrangement of the sampling nozzle for the supply line in this area ensures the effective utilization of the cleaning liquid, especially at a low level in the container. In a complicated configuration of the container can be dispensed with, if the bottom of the container has a slope inclined to the removal point.

Die geneigte Anordnung des Behälters kann in einer weiteren Ausgestaltung zur Verriegelung des Behälters benutzt werden, indem die Verriegelung über die Hangabtriebskraft erfolgt. Der Behälter wird hierzu in die Reinigungsvorrichtung eingesetzt und über eine geneigte Ebene in seine Raststellung bewegt, wo er durch ein Verrasten zuverlässig in dieser Position gehalten wird. Der Vorteil dieser Ausgestaltung besteht darin, daß dem Benutzer mit dem Verrasten gleichzeitig die richtige Position des Behälters angezeigt wird.The inclined arrangement of the container can be used in a further embodiment for locking the container by the locking takes place via the slope-down force. The container is used for this purpose in the cleaning device and moved over an inclined plane in its detent position, where it is reliably held by a latching in this position. The advantage of this embodiment is that the user is displayed with the latching the correct position of the container at the same time.

In einer weiteren Ausgestaltung besitzt der Behälter zumindest einen transparenten Wandbereich, vorzugsweise ein Sichtfenster. Dadurch läßt sich der Füllstand im Behälter durch den Benutzer ohne zusätzlichen Aufwand feststellen, wenn der Behälter durch eine Ausnehmung im Gehäuse der Reinigungsvorrichtung einsehbar ist. Gleichzeitig kann der Benutzer den Zeitpunkt für den Wechsel des Behälters nunmehr nach den tatsächlichen Gegebenheiten bestimmen, ohne feste Wechselintervalle, etwa in Abhängigkeit von der Anzahl durchgeführter Reinigungen einhalten zu müssen. In einer besonders komfortablen Ausgestaltung besitzt die Reinigungsvorrichtung anstelle der Gehäuseausnehmung ein Sichtfenster, durch das der transparente Wandbereich des Behälters einsehbar ist. Dadurch kann der Benutzer den Behälter einsehen, ohne ihn vorher aus der Reinigungsvorrichtung entnehmen zu müssen. Das Sichtfenster gewährleistet darüber hinaus den Schutz des Inneren der Reinigungsvorrichtung vor Verschmutzung und Feuchtigkeit.In a further embodiment, the container has at least one transparent wall region, preferably a viewing window. As a result, the level in the container can be determined by the user without additional effort when the container is visible through a recess in the housing of the cleaning device. At the same time, the user can now determine the time for changing the container according to the actual conditions, without having to comply with fixed change intervals, for example, depending on the number of performed cleanings. In a particularly convenient embodiment, the cleaning device has a viewing window instead of the housing recess, through which the transparent wall portion of the container is visible. This allows the user to see the container without having to remove it from the cleaning device before. The window also ensures the protection of the interior of the cleaning device from dirt and moisture.

Die Reinigungsvorrichtung gestaltet sich in einer weiteren Ausgestaltung besonders komfortabel für den Benutzer, wenn in dem Gehäuse ein von außen zugänglicher Stauraum ausgebildet ist. Dieser Stauraum kann vom Benutzer zur Aufbewahrung verschiedenster Dinge, z.B. Netzkabel, Schutzkappe, Bürste, genutzt werden. Der Stauraum gestaltet sich besonders nutzerfreundlich, wenn er bereits eine Unterteilung oder entsprechenden Halterungen für verschiedene Gegenstände aufweist. Die im Stauraum aufbewahrten Gegenstände sind besonders gut gegen Umwelteinflüsse oder ein Herausfallen bei einem Transport geschützt, wenn der Stauraum, z.B. durch eine Klappe nach außen verschließbar ist. Aufgrund der im wesentlichen waagerechten Anordnung des Trockenrasierapparates und dem darunter vorgesehenen Behälter für die Reinigungsflüssigkeit ist der Stauraum in vorteilhafter Weise neben dem Behälter und unter dem Trockenrasierapparat angeordnet, so daß der Bauraum der Reinigungsvorrichtung optimal ausgenutzt wird.The cleaning device is designed in a further embodiment particularly comfortable for the user when formed in the housing accessible from the outside storage space is. This storage space can be used by the user to store a variety of things, such as power cord, protective cap, brush. The storage space is particularly user-friendly if it already has a subdivision or corresponding mounts for various items. The items stored in the storage space are particularly well protected against environmental influences or falling out during transport, if the storage space, eg by a flap can be closed to the outside. Due to the substantially horizontal arrangement of the dry shaver and the container provided below for the cleaning liquid, the storage space is advantageously arranged next to the container and under the dry shaver, so that the space of the cleaning device is optimally utilized.

Die Bedienerfreundlichkeit und Betriebssicherheit für den Benutzer wird zusätzlich dadurch erhöht, daß das Gehäuse ein Display zur Anzeige von Betriebsdaten wie z.B. des aktuellen Betriebszustandes aufweist. Darüber hinaus können weitere Informationen, z.B. der Ladezustand des Trockenrasierapparates in dem Display dargestellt werden.The user-friendliness and operational safety for the user is further enhanced by the fact that the housing has a display for displaying operating data such as e.g. of the current operating state. In addition, further information, e.g. the state of charge of the dry shaver can be displayed in the display.

Weiterhin können an dem Gehäuse Funktionstasten zur Bedienung der Reinigungsvorrichtung angeordnet sein.Furthermore, function keys for operating the cleaning device can be arranged on the housing.

Zur Verbesserung des Reinigungsprozesses wird der Scherkopf nach erfolgter Reinigung in einem Luftstrom getrocknet. Für die Erzeugung des Luftstroms ist in dem Gehäuse ein Lüfter angeordnet, durch den der Scherkopf mit einem Luftstrom beaufschlagbar ist. Der Lüfter ist besonders effektiv, wenn er in der Nähe des Scherkopfes angeordnet ist, so daß der Luftstrom auf möglichst kurzem Weg, z.B. durch einen Kanal, auf den Scherkopf leitbar ist. Eine eventuell auftretende Geruchsbelästigung läßt sich in einer verbesserten Ausgestaltung wirksam vermeiden, wenn in dem Kanal ein Filter, insbesondere ein Aktivkohlefilter angeordnet ist.To improve the cleaning process, the shaving head is dried after cleaning in a stream of air. For the generation of the air flow, a fan is arranged in the housing, through which the shaving head can be acted upon with an air flow. The fan is particularly effective when placed near the shaving head so that the airflow is as short as possible, e.g. through a channel, on the shaving head is conductive. A possibly occurring odor nuisance can be effectively avoided in an improved embodiment, if in the channel a filter, in particular an activated carbon filter is arranged.

Über eine entsprechende Kontaktvorrichtung ist der Trockenrasierapparat mit der Reinigungsvorrichtung elektrisch verbindbar. Die Reinigungsvorrichtung gestaltet sich besonders komfortabel, wenn in einer Wand der wannenförmigen Aufnahme eine Kontaktvorrichtung angeordnet ist, über die der in die Aufnahme eingesetzte Trockenrasierapparat mit einem Ladesystem für den Trockenrasierapparat, vorzugsweise einem induktiv arbeitenden Ladesystem, verbindbar ist. Gleichzeitig kann das Ladesystem zum Steuern des Trockenrasierapparates während des Reinigungsprozesses verwendet werden.About a corresponding contact device of the dry shaver with the cleaning device is electrically connected. The cleaning device is particularly convenient if in a wall of the trough-shaped receptacle, a contact device is arranged, via which the dry shaver used in the recording with a charging system for the dry shaver, preferably an inductively operating charging system, is connectable. At the same time, the loading system can be used to control the dry shaver during the cleaning process.

Zur Unterstützung des Reinigungsprozesses wird der Scherkopf während der Reinigung zumindest zeitweise in Betrieb genommen. Das Ein- und Ausschalten des Trockenrasierapparates während des Reinigungsprozesses gestaltet sich besonders einfach, wenn der Trockenrasierapparat mit seinem Betriebsschalter nach unten in die Reinigungsvorrichtung einsetzbar ist. Besitzt der Betriebsschalter des Trockenrasierapparates einen Reed-Kontaktschalter, so ist dieser in einer vorteilhaften Ausführung mit einem Elektromagneten betätigbar, der dem Betriebsschalter gegenüberliegend in der Aufnahme angeordnet ist. Die Aufnahme besitzt hierzu eine Ausnehmung für den Betriebsschalter, so daß der Trockenrasierapparat sicher in der Aufnahme angeordnet ist. Das Ausladen und Schalten des Trockenrasierapparates während des Reinigungsprozesses kann auch mittels induktivem Ankoppeln oder durch außenliegende, insbesondere abgedichtete elektrische Kontakte erfolgen.To support the cleaning process, the shaving head is at least temporarily put into operation during cleaning. The switching on and off of the dry shaver during the cleaning process is particularly simple if the dry shaver with its operating switch down into the cleaning device can be used. If the operating switch of the dry shaver has a reed contact switch, this can be actuated in an advantageous embodiment with an electromagnet, which is arranged opposite the operating switch in the receptacle. The receptacle has for this purpose a recess for the operating switch, so that the dry shaver is securely arranged in the receptacle. The unloading and switching of the dry shaver during the cleaning process can also be done by means of inductive coupling or by external, in particular sealed electrical contacts.

a perspective view of the cleaning device according to FIG. 1 ,

Die Figur 1 zeigt eine Reinigungsvorrichtung mit einem Gehäuse 1, in das ein Trockenrasierapparat 2 eingesetzt ist. Der Scherkopf 3 des Trockenrasierapparates 2 ist in einer Öffnung 4 eines Aufnahmebereichs 5 angeordnet. Zur sicheren Lage des Trockenrasierapparates 2 ist dieser in einer wannenförmigen, an die Kontur des Trockenrasierapparates 2 angepaßten Aufnahme 6 eingelegt. Die Aufnahme 6 besitzt eine Ausnehmung 7 für den Betriebsschalter 8 des Trockenrasierapparates 2 und ist gegenüber der Aufstandsfläche 9 um einen Winkel α von 5° geneigt.The FIG. 1 shows a cleaning device with a housing 1, in which a dry shaver 2 is inserted. The shaving head 3 of the dry shaving apparatus 2 is arranged in an opening 4 of a receiving region 5. For safe location of the dry shaver 2 this is inserted in a trough-shaped, adapted to the contour of the dry shaver 2 receptacle 6. The receptacle 6 has a recess 7 for the operating switch 8 of the dry shaver 2 and is inclined relative to the footprint 9 by an angle α of 5 °.

Über eine Kontaktvorrichtung 10 eines nicht näher dargestellten induktiven Ladesystems in dem Gehäuse 1 ist der Trockenrasierapparat 2 sowohl gegen eine Entnahme während des Reinigungsprozesses verriegelbar als auch elektrisch kontaktierbar. Unterhalb des Betriebsschalters 8 ist in dem Gehäuse 1 ein Elektromagnet 11 angeordnet, der mit dem im Trockenrasierapparat 2 vorhandenen Reed-Kontaktschalter zum Ansteuern des Trockenrasierapparates 2 zusammenwirkt.About a contact device 10 of an inductive charging system in the housing 1, not shown, the dry shaver 2 against both removal during the cleaning process can be locked and electrically contacted. Below the operating switch 8, an electromagnet 11 is arranged in the housing 1, which cooperates with the present in the dry shaver 2 reed contact switch for driving the dry shaver 2.

In dem Gehäuse 1 ist unterhalb des Trockenrasierapparates 2 der austauschbare Behälter 12 für die Reinigungsflüssigkeit 13 angeordnet. Über eine Zuführleitung 14 wird mittels einer nicht dargestellten Pumpe die Reinigungsflüssigkeit 13 in den Aufnahmebereich 5 gefördert. An dem zum Aufnahmebereich 5 gerichteten Ende der Zuführleitung 14 ist eine Flachstrahldüse 16 angeordnet. Die Flachstrahldüse 16 ist auf den Scherkopf 3 des Trockenrasierapparates 2 gerichtet. Über die Flachstrahldüse 16 wird die Reinigungsflüssigkeit 13 auf den gesamten oberen Bereich des Scherkopfes 3 aufgesprüht. Infolge der Bewegung der im Inneren befindlichen Scherteile wird die Reinigungsflüssigkeit 13 im gesamten Scherkopf 3 verteilt. Im unteren Bereich des Aufnahmebereichs 5 ist eine Rücklaufleitung 17 angeordnet, über die die sich ansammelnde Reinigungsflüssigkeit 13 zurück in den Behälter 12 geleitet wird.In the housing 1, the exchangeable container 12 for the cleaning liquid 13 is arranged below the dry shaver 2. Via a supply line 14 is by means of a pump, not shown, the cleaning liquid 13 conveyed into the receiving area 5. At the end of the supply line 14 directed to the receiving region 5, a flat-jet nozzle 16 is arranged. The flat jet nozzle 16 is directed to the shaving head 3 of the dry shaver 2. About the fan nozzle 16, the cleaning liquid 13 is sprayed onto the entire upper portion of the shaving head 3. As a result of the movement of the inside shaving parts, the cleaning liquid 13 is distributed throughout the shaving head 3. In the lower region of the receiving area 5, a return line 17 is arranged, via which the accumulating cleaning liquid 13 is passed back into the container 12.

Um ein Austreten von Reinigungsflüssigkeit 13 aus der Öffnung 4 zu vermeiden, ist um die Öffnung 4 eine Dichtmanschette 18 angeordnet, die den Scherkopf 3 gegen die Öffnung 4 abdichtet. Dennoch kann beim Entnehmen des Trockenrasierapparates 2 nach erfolgtem Reinigungsprozeß Reinigungsflüssigkeit nach außen gelangen. Ein zusätzlich im Bereich der Öffnung 4 angeordneter Bypass 19 ermöglicht das Rückführen dieser Reinigungsflüssigkeit 13 in den Behälter 12.In order to prevent leakage of cleaning liquid 13 from the opening 4, a sealing collar 18 is arranged around the opening 4, which seals the shaving head 3 against the opening 4. Nevertheless, when the dry shaver 2 is removed, cleaning liquid can escape to the outside after the cleaning process has been completed. An additionally arranged in the region of the opening 4 bypass 19 allows the return of this cleaning liquid 13 in the container 12th

Der Behälter 12 für die Reinigungsflüssigkeit 13 enthält eine Kaskade 20 topf- oder rinnenförmiger Aufnahmebehälter 15. Die Kaskade 20 besitzt einen stufenförmigen Aufbau und ist mit ihrem obersten Aufnahmebehälter 15 unmittelbar unterhalb der in den Behälter 12 einmündenden Rücklaufleitung 17 angeordnet. Jeder Aufnahmebehälter 15 der Kaskade 20 besitzt ein Sperrelement 21 zu dem nächst tiefer gelegenen Aufnahmebehälter 15. Durch dieses in Form einer Wand ausgebildete Sperrelement 21 wird in jedem Aufnahmebehälter 15 ein beruhigter Bereich geschaffen, in dem sich die von der Reinigungsflüssigkeit 13 mitgeführten Partikel absetzen können. Bis zum Erreichen des untersten Aufnahmebehälters 15 ist die Reinigungsflüssigkeit 13 auf diese Weise wesentlich weniger mit Haarresten und anderen Partikeln belastet als zu Beginn der Kaskade. Dadurch gelangt weniger verschmutzte Reinigungsflüssigkeit 13 bis zum Boden des Behälters 12. Die wenigen zu diesem Zeitpunkt noch in der Reinigungsflüssigkeit 13 enthaltenen Partikel können sich anschließend am Boden des Behälters 12 ablagern. Mittels eines Filters 22 wird die Reinigungsflüssigkeit 13 bei einer erneuten Förderung von den noch enthaltenen Partikeln befreit.The container 12 for the cleaning liquid 13 contains a cascade 20 cup or trough-shaped receptacle 15. The cascade 20 has a stepped structure and is arranged with its uppermost receptacle 15 immediately below the opening into the container 12 return line 17. Each receptacle 15 of the cascade 20 has a blocking element 21 to the next lower receptacle 15. By this formed in the form of a wall blocking element 21 in each receptacle 15 a calmed area is created in which the entrained by the cleaning liquid 13 particles can settle. Until reaching the lowermost receptacle 15, the cleaning liquid 13 is loaded in this way much less with hair residues and other particles than at the beginning of the cascade. As a result, less soiled cleaning liquid 13 reaches the bottom of the container 12. The few particles still present in the cleaning liquid 13 at this time can then deposit on the bottom of the container 12. By means of a filter 22, the cleaning liquid 13 is freed in a further promotion of the particles still contained.

Oberhalb des Aufnahmebereichs 5 ist ein Lüfter 23 angeordnet. Über einen Kanal 24 wird der vom Lüfter 23 erzeugte Luftstrom nach der Reinigung mit der Reinigungsflüssigkeit 13 auf den Scherkopf 3 geleitet, um diesen zu trocknen.Above the receiving area 5, a fan 23 is arranged. Via a channel 24, the air flow generated by the fan 23 is passed after cleaning with the cleaning liquid 13 on the shaving head 3 in order to dry it.

lm Bereich des Lüfters 23 ist ein Display 25 zur Anzeige verschiedenster Informationen zum Reinigungsprozeß und des Ladezustandes des Trockenrasierapparates 2 vorgesehen. Die verschiedenen Funktionen der Reinigungsvorrichtung 1 lassen sich über Funktionstasten 26 einstellen.In the area of the fan 23, a display 25 for displaying a wide variety of information about the cleaning process and the state of charge of the dry shaver 2 is provided. The various functions of the cleaning device 1 can be adjusted via function keys 26.

Neben dem Behälter 12 ist ein Stauraum 27 vorgesehen, der ausreichend Platz für die Schutzkappe 31 und das Netzkabel des Trockenrasierapparates 2 bietet. Der Stauraum ist mit einer nicht dargestellten Klappe verschließbar.In addition to the container 12, a storage space 27 is provided, which provides sufficient space for the protective cap 31 and the power cord of the dry shaver 2. The storage space can be closed with a flap, not shown.

In der Figur 2 ist die Reinigungsvorrichtung ohne den Trockenrasierapparat dargestellt. Im Bereich des Aufnahmebereichs 5 befindet sich an der Vorderseite des Gehäuses 1 eine weitere Öffnung 28, in der ein Aktivkohlefilter 29 angeordnet ist. Über diesen Aktivkohlefilter 29 verläßt der zur Trocknung des Scherkopfes 3 vom Lüfter 23 erzeugte Luftstrom die Reinigungsvorrichtung.In the FIG. 2 the cleaning device is shown without the dry shaver. In the region of the receiving region 5 is located at the front of the housing 1, a further opening 28 in which an activated carbon filter 29 is arranged. About this activated carbon filter 29 leaves the air flow generated by the fan 23 for drying the shaving head 3, the cleaning device.

An der Vorderseite des Gehäuses 1 befindet sich unterhalb des Halteteils 7 ein Sichtfenster 30. Durch das Sichtfenster 30 ist der Behälter 12 einsehbar, der in diesem Bereich eine transparente Wandung besitzt. Dadurch wird es dem Benutzer der Reinigungsvorrichtung ermöglicht, den Füllstand und den Verschmutzungsgrad der Reinigungsflüssigkeit 13 festzustellen. At the front of the housing 1 is located below the holding part 7, a viewing window 30. Through the viewing window 30 of the container 12 is visible, which has a transparent wall in this area. This allows the user of the cleaning device to determine the level and the degree of soiling of the cleaning liquid 13.
