Bei diesem bekannten Trockenrasierapparat ist es erforderlich, den Scherkopf des Trockenrasierapparates in mehrere Teile zu zerlegen. Diese Teile, wie z.B. Wechselrahmen, Untermesser, Kupplungselement, sowie Gehäuseteil des Scherkopfes werden abgelegt, wodurch an mehreren Stellen im Waschbecken eines Bades sich Verschmutzungen durch Haarstaub einstellen. Schaltet der Benutzer den Trockenrasierapparat ohne Wechselrahmen jedoch mit gekoppeltem Untermesser ein, wird gelöster Haarstaub über eine größere Fläche des Waschbeckens verteilt.In this known dry shaver, it is necessary to shear the shaving head of the dry shaver to disassemble into several parts. These parts, e.g. Interchangeable frame, lower knife, Coupling element, as well as the housing part of the shaving head are deposited, whereby in several places in the sink of a bathroom there is dirt from hair dust to adjust. However, the user switches on the dry shaver without a removable frame coupled bottom knife, loosened hair dust over a larger area of the Washbasin distributed.

Aufgabe der Erfindung ist es, die Reinigung des Scherkopfes, und zwar der vom Gehäuseteil und dem abnehmbaren Wechselrahmen gebildeten Haarstaubkammer sowie der vorgesehenen Schneidelemente, insbesondere der als Untermesser zum Einsatz kommenden Schneidelemente auf einfache Weise und mit minimalem Aufwand zu bewerkstelligen. The object of the invention is to clean the shaving head, namely that of the housing part and the removable interchangeable frame made of hair dust chamber and the intended Cutting elements, in particular those used as bottom knives Cutting elements can be accomplished in a simple manner and with minimal effort.

Nach der Erfindung wird diese Aufgabe bei einem Trockenrasierapparat der eingangs genannten Art durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Diese Lösung nach der Erfindung weist mehrere Vorteile auf, die beispielsweise darin bestehen, daß durch Betätigung der Betätigungseinrichtung der Wechselrahmen vom Gehäuseteil zunächst gelöst wird, um anschließend von einer Haltevorrichtung in einer Haltestellung bewegbar gehalten zu werden, in der wenigstens ein Abstand zwischen wenigstens einer Wand des Wechselrahmens und wenigstens einer Wand des Gehäuseteils hergestellt ist, so daß sowohl die Bewegbarkeit des Wechselrahmens als auch das Herausfallen vorhandenen Haarstaubes durch diesen Abstand aus der Haarstaubkammer gewährleistet ist. Um ohne Abnahme des Wechselrahmens vom Gehäuseteil jederzeit, z.B. täglich eine Grundreinigung des Scherkopfes d.h. eine Entfernung von Haarstaub aus der Haarstaubkammer, der sowohl an den Wänden des Gehäuseteils als auch an den Wänden des Wechselrahmens und der Schneidteile haftet, durchführen zu können, ist nach der Erfindung der Wechselrahmen in der von der Haltevorrichtung gehaltenen Haltestellungen durch Inbetriebnahme des elektrischen Antriebes in Bewegung zu versetzen, so daß über diese Bewegung des Wechselrahmens und der den Wechselrahmen in Bewegung versetzenden Antriebselemente der an den Wänden des Wechselrahmens, der Schneidelemente sowie an den Wänden des Gehäuseteils anhaftende Haarstaub gelöst bzw. weitestgehend gelöst wird, um danach aus den gebildeten Abständen herauszufallen, um die Entfernung von Haarstaub aus der Haarstaubkammer zu optimieren.According to the invention, this object is achieved in a dry shaver of the type mentioned Type solved by the features specified in the characterizing part of claim 1. This solution according to the invention has several advantages, which are, for example, that by actuating the actuator of the removable frame from the housing part is first released, then from a holding device in a holding position to be kept movable, at least a distance between at least a wall of the removable frame and at least one wall of the housing part is, so that both the mobility of the removable frame and falling out existing Hair dust is guaranteed by this distance from the hair dust chamber. In order to remove the removable frame from the housing part at any time, e.g. one daily Basic cleaning of the shaving head i.e. removal of hair dust from the hair dust chamber, of both on the walls of the housing part and on the walls of the removable frame and the cutting parts are liable to be able to perform, according to the invention Removable frame in the holding positions held by the holding device by commissioning to set the electric drive in motion, so that this movement of the change frame and the drive elements that set the change frame in motion the on the walls of the removable frame, the cutting elements and on the Hair dust adhering to the walls of the housing part is loosened or largely loosened then fall out of the gaps formed to remove hair dust optimize from the hair dust chamber.

Die Erfindung gewährleistet sonach eine Grundreinigung des Scherkopfes ohne daß hierzu der Scherkopf in mehrere Teile zerlegt werden muß, wie z.B.

Fig. 4 zeigt den oberen Teil des Gehäuses 1 mit einem darauf angeordneten Gehäuseteil G, nach einem in Entnahmerichtung Pfeilrichtung E abnehmbaren Wechselrahmen WR, wobei der eine Steg 32 des Wechselrahmens WR sowie das mit diesem gekoppelte Obermesser nur teilweise dargestellt sind. Der Wechselrahmen WR ist in einem von den Halteelementen 28 und 29 mittels dieser umgreifenden Halteelemente 30 und 31gehaltenen Zustand - siehe auch Fig. 5 - dargestellt. Im entriegelten Zustand des Wechselrahmens WR befinden sich die Rastelemente 18,19 außerhalb der im Wechselrahmen WR vorgesehenen Rastöffnungen 20, 21, wie dies beispielsweise in Fig. 4 anhand des Rastelementes 18 und der Rastöffnung 20 mittels unterbrochenen Linien dargestellt ist.4 shows the upper part of the housing 1 with a housing part G arranged thereon, after a removable frame WR removable in the direction of arrow E, whereby one web 32 of the interchangeable frame WR and the upper knife coupled to it are only partially shown. The interchangeable frame WR is in one of the holding elements 28 and 29 held by means of these encompassing holding elements 30 and 31 - see also Fig. 5 - shown. In the unlocked state of the interchangeable frame WR are the locking elements 18, 19 outside the locking openings provided in the interchangeable frame WR 20, 21, as is the case, for example, in FIG. 4 with the aid of the latching element 18 and the latching opening 20 is shown by means of broken lines.

Der Wechselrahmen WR besteht im wesentlichen aus zwei in Längsrichtung - Pfeilrichtung P - verlaufenden Stegen 32 und 33 sowie diese Stege 32 und 33 verbindende Stirnseitenwände 34 und 35, - siehe Fig. 5- sowie wenigstens einem zwischen den Stegen 32, 33 und Stirnseitenwänden 34, 35 angeordneten Schneidelement S. Die Innenwände 36 und 37 der Stirnwände 13 und 14 sowie die Außenwände 38 und 39 der Stirnseitenwände 34 und 35 verlaufen keilförmig zur vertikalen Mittenachse V des Trockenrasierapparates TR derart, daß der Abstand der Stirnwände 13 und 14 zueinander im Bereich des Gehäusemittenteils 15 geringer ist als der Abstand der Stirnwände 13 und 14 in Höhe des Schneidelementes S. Diese Formgebung hat zur Folge, daß die sich im verriegelten Zustand des Wechselrahmens WR mit dem Gehäuseteil G die Stirnseitenwände 34 und 35 die Innenwände 36 und 37 der Stirnwände 13 und 14 berühren bzw. nahezu berühren. Im entriegelten Zustand in dem der Wechselrahmen WR zunächst von den Halteelementen 28 bis 31 gehalten ist, nehmen die Stirnseitenwände 34 und 35 einen geringen Abstand W zu den Innenwänden 36 und 37 sowie den Längsseitenwänden 53, 54 des Gehäuseteils G ein - siehe auch Fig. 8 -.The interchangeable frame WR essentially consists of two in the longitudinal direction - arrow direction P - extending webs 32 and 33 and end walls connecting these webs 32 and 33 34 and 35, - see Fig. 5- and at least one between the webs 32, 33 and Front side walls 34, 35 arranged cutting element S. The inner walls 36 and 37 of the End walls 13 and 14 and the outer walls 38 and 39 of the end side walls 34 and 35 run in a wedge shape to the vertical center axis V of the dry shaver TR such that the spacing of the end walls 13 and 14 from one another in the region of the housing middle part 15 is less than the distance between the end walls 13 and 14 at the level of the cutting element S. The result of this design is that it is in the locked state of the removable frame WR with the housing part G, the end walls 34 and 35, the inner walls 36 and 37 touch or almost touch the end walls 13 and 14. When unlocked in which the interchangeable frame WR is initially held by the holding elements 28 to 31, the front side walls 34 and 35 take a small distance W from the inner walls 36 and 37 and the longitudinal side walls 53, 54 of the housing part G a - see also Fig. 8 -.

An den beiden Stirnseitenwänden 34 und 35 sind jeweils ein nach innen gerichteter Anschlag 40 und 41 sowie ein nach außen gerichteter Anschlag 42 und 43 vorgesehen. Die äußere Form der dem Untermesser 22 zugewandten Anschläge 40 und 41 sowie die Formgebung der Längsenden 44 und 45 des Untermessers 22 und die Positionierung der Anschläge 40 und 41 am Wechselrahmen WR in Zusammenwirken mit dem Untermesser 22 sind derart aufeinander abgestimmt, daß im verriegelten Zustand des Wechselrahmens WR mit dem Gehäuseteil G die Anschläge 40 und 41 in das Untermesser 22 hineingleiten können, ohne dessen Oszillationsbewegung zu beeinträchtigen.On the two end walls 34 and 35 are an inwardly directed stop 40 and 41 and an outwardly directed stop 42 and 43 are provided. The outer shape of the stops 40 and 41 facing the lower knife 22 and the shape the longitudinal ends 44 and 45 of the lower knife 22 and the positioning of the stops 40 and 41 on the interchangeable frame WR in cooperation with the lower knife 22 are matched to each other in such a way that in the locked state of the interchangeable frame WR the stops 40 and 41 can slide into the lower knife 22 with the housing part G, without affecting its oscillatory movement.

Durch Betätigen der Betätigungstasten 16, 17 wird der Wechselrahmen WR entriegelt. Der mit seinen Rastöffnungen 20, 21 über die Rastelemente 18, 19 hinweggleitende Wechselrahmen WR wird danach von den die Halteelemente 28, 29, teilweise umgreifenden federelastisch ausgebildeten Haltearme der Halteelemente 30, 31 in einer vorgegebenen Haltestellung bewegbar gehalten. By pressing the actuation buttons 16, 17, the removable frame WR is unlocked. The with its latching openings 20, 21 removable frames sliding over the latching elements 18, 19 WR then becomes resilient from the partially encompassing the holding elements 28, 29 trained holding arms of the holding elements 30, 31 in a predetermined holding position kept movable.

Durch die Überführung des Wechselrahmens WR in die Haltestellung stellt sich bedingt durch den keilförmigen Verlauf der Außenwände 38, 39 des Wechselrahmens und der parallel zu diesen verlaufenden Innenwände 36, 37 der Stirnwände 13, 14 jeweils ein Abstand W zwischen der jeweiligen Innenwand 36, 37 und der jeweiligen Außenwand 38, 39 ein. Jeder der beiden Abstände W gewährleistet zunächst eine hin und hergehende Bewegung des Wechselrahmens WR in den Pfeilrichtungen P und darüber hinaus einen vorhandenen Haarstaub durchlassenden Spalt. Zusätzlich stellt sich zwischen wenigstens einer der Längsseitenwände 53, 54 des Gehäuseteils G und wenigstens einem der Stege 32, 33 des Wechselrahmens WR wenigstens ein Haarstaub durchlassender weiterer spaltförmiger Abstand W ein.The transfer of the interchangeable frame WR into the holding position results in certain conditions due to the wedge-shaped course of the outer walls 38, 39 of the removable frame and the parallel a distance from each of these extending inner walls 36, 37 of the end walls 13, 14 W between the respective inner wall 36, 37 and the respective outer wall 38, 39. Everyone of the two distances W initially ensures a back and forth movement of the Interchangeable frame WR in the arrow directions P and beyond an existing one Gap permitting hair dust. In addition, between at least one of the Longitudinal side walls 53, 54 of the housing part G and at least one of the webs 32, 33 of the Interchangeable frame WR at least a further gap-shaped gap permitting hair dust Wine.

Der Abstand W kann als ein sich durch die Überführung des Wechselrahmens WR von der Raststellung in die Haltestellung ergebender umlaufender spaltartiger Abstand ausgebildet sein, der sowohl gleichbleibend groß als auch unterschiedlich groß bemessen sein kann.The distance W can be determined by the transfer of the change frame WR from the Locking position formed in the holding position circumferential gap-like distance be, which can be both consistently large and of different sizes.

Durch die Überführung des Wechselrahmens WR in die Haltestellung nehmen die beiden Anschläge 40, 41 eine gegenüber dem Untermesser 22 geänderte Position ein, in der ein Eindringen der Anschläge 40, 41 in das Untermesser 22 ausgeschlossen ist. Der Abstand D der jeweiligen Längsenden 44, 45 zu den Anschlägen 40, 41 ist derart bemessen, daß bei einem durch Einschalten des elektrischen Antriebes in Schwingungen versetzten Untermessers 22 gewährleistet ist, daß die Längsenden 44, 45 des Untermessers 22 die Anschläge 40, 41 impulsartig beaufschlagen, um den Wechselrahmen WR in Bewegungsrichtung - Pfeilrichtung P - des Untermessers 22 hin und herzubewegen bzw. zu schütteln. Mittels der vom Untermesser 22 auf den Wechselrahmen WR ausgeübten Schlagimpulse löst sich der relativ feine Haarstaub von den Wänden des Wechselrahmens WR, des Untermessers 22 sowie von den Wänden des Gehäuseteils G und fällt beispielsweise bei horizontaler Haltung des Trockenrasierapparates TR durch die zwischen dem Gehäuseteil G und den Wänden des Wechselrahmens WR gebildeten Öffnungen - wie z.B. durch die Spalte der Abstände W - nach außen.By transferring the interchangeable frame WR into the stop position, the two take Stops 40, 41 a changed position relative to the lower knife 22, in which a Penetration of the stops 40, 41 into the lower knife 22 is excluded. The distance D the respective longitudinal ends 44, 45 to the stops 40, 41 is dimensioned such that at a lower blade set in vibration by switching on the electric drive 22 ensures that the longitudinal ends 44, 45 of the lower knife 22 are the stops 40, 41 act on impulses in order to move the interchangeable frame WR in the direction of movement - Arrow direction P - to move the lower knife 22 back and forth or to shake it. By means of the The impact impulses exerted by the lower knife 22 on the exchangeable frame WR are released relatively fine hair dust from the walls of the interchangeable frame WR, the lower knife 22 as well as from the walls of the housing part G and falls, for example, when held horizontally of the dry shaver TR through the between the housing part G and the walls of the interchangeable frame WR - such as through the column of distances W - outward.

Die Reinigung sämtlicher vom Wechselrahmen WR umschlossener Wände kann durch eine weitere Maßnahme optimiert werden. Zu diesem Zweck sind an den Stirnseitenwänden 34, 35 des Wechselrahmens WR die nach außen gerichteten Anschläge 42, 43 vorgesehen, mittels denen der Abstand W der Außenwände 38, 39 des Wechselrahmens WR zu den Innenwänden 36, 37 der Stirnwände 13, 14 jeweils verringert wird auf einen Spalt W1, dessen Breite unter praxisgerechten Gesichtspunkten im jeweiligen Anwendungsfall - d.h. Ausbildung eines Scherkopfes - zu ermitteln und festzulegen ist. Mittels der Anschläge 42, 43 werden die von einem oszillierenden Untermesser 22 auf die Anschläge 40, 41 ausgeübten Schlagimpulse auf die Stirnwände 13, 14 des Gehäuseteils G weitergeleitet, um diesen ebenfalls in eine den Reinigungsprozeß unterstützende Vibration zu versetzen.All walls enclosed by the interchangeable frame WR can be cleaned by a further measure can be optimized. For this purpose, on the end walls 34, 35 of the interchangeable frame WR, the outwardly directed stops 42, 43 are provided, by means of which the distance W of the outer walls 38, 39 of the interchangeable frame WR to the Inner walls 36, 37 of the end walls 13, 14 are each reduced to a gap W1, the Width from a practical point of view in the respective application - i.e. education of a shaving head - to be determined and determined. By means of the stops 42, 43 are exerted on the stops 40, 41 by an oscillating bottom knife 22 Impact impulses forwarded to the end walls 13, 14 of the housing part G to this also to put in a vibration supporting the cleaning process.
