Description

Automatisch gesteuerte Waschmaschine mit Füllstandsanzeige für Wäschebehandlungsmittel  Automatically controlled washing machine with level indicator for laundry treatment
Die Erfindung betrifft eine automatisch gesteuerte Waschmaschine mit einer im Maschinenraum frontseitig angeordneten Einspüleinrichtung fürThe invention relates to an automatically controlled washing machine with a front in the machine room arranged flushing device for
Wäschebehandlungsmittel, die eine von vorn zugängliche Schublade mit mindestens einem Vorratsbehälter für einen mehrere Dosen umfassenden Vorrat an flüssigem oder gelförmigem Wäschebehandlungsmittel und eine an der Schublade fest verbundene Handhabe zum Aufziehen und Einschieben der Schublade enthält. Laundry treatment composition containing a front-accessible drawer with at least one reservoir for a multi-dose supply of liquid or gel laundry treatment agent and a firmly attached to the drawer handle for mounting and insertion of the drawer.
In der DE 10 2009 027 127.9 der Anmelderin ist eine Waschmaschine der eingangs genannten Art beschrieben, in der ein Ausführungsbeispiel einen Vorratsbehälter aufweist, der direkt hinter der Handhabe, einer Griffplatte, einen prismatischen Raumteil hat, der eine zum Betrachter schräg nach vorn abfallende, zumindest durchscheinende Sichtfläche aufweist. An dieser Sichtfläche sind Markierungen für die Füllhöhe des Vorratsbehälters angebracht, an denen der Betrachter die ungefähre Füllhöhe des betreffenden Vorratsbehälters ablesen kann. Allerdings muss der Betrachter dazu zunächst die Schublade aufziehen. Bei einem bekannten Wäschetrockner (DE 37 08 516 A1 ) ist der Füllungsgrad eines Kondensatsammelbehälters anhand eines Wasserstandsröhrchens abzulesen, das an der Griffplatte des Sammelbehälters angebracht ist. Hier handelt es sich allerdings um ein Merkmal an einem Wäschetrockner und um die Beobachtung des Vollzustandes des Kondensatsammelbehälters. In DE 10 2009 027 127.9 of the Applicant a washing machine of the type mentioned is described in which an embodiment has a reservoir which has directly behind the handle, a handle plate, a prismatic space part, the obliquely sloping forward to the viewer, at least has translucent viewing surface. On this visible surface markings for the filling level of the reservoir are attached, where the viewer can read the approximate level of the reservoir in question. However, the observer must first open the drawer. In a known tumble dryer (DE 37 08 516 A1), the degree of filling of a condensate collection tank is read using a water level tube, which is attached to the handle plate of the collecting container. However, this is a feature on a tumble dryer and the observation of the full state of the condensate collection tank.
Die WO 2009/142 355 A1 offenbart eine Waschmaschine mit einem Aufsatz für kommerzielle Waschmittelflaschen, der eine Befüllung der Einspülschale mit Flüssigwaschmittel ermöglicht, wobei eine vorbestimmte Menge an Waschmittel abgefüllt werden kann. Der Nachteil an dieser Lösung ist, dass keine Vorratsbehälter in der Waschmaschine vorgesehen sind. Stattdessen müssen die Waschmittelflaschen für jeden Waschgang auf den Aufsatz aufgesetzt werden. Die offenbarte Füllstandsanzeige für die Einspülschale gibt somit keinen Aufschluss über den noch vorhandenen Waschmittelvorrat, sondern gibt nur über die Menge einer Einmaldosis an Waschmittel. Der Erfindung liegt die Aufgabe zugrunde, eine eingangs beschriebene Waschmaschine so auszubilden, dass die Überwachung einer Entleerung von Vorratsbehältern für den Benutzer in der Weise vereinfacht ist, dass er zum Ablesen eines Mangels im Vorratsbehältervorrat die Schublade der Waschmitteleinspüleinrichtung nicht aufziehen muss. WO 2009/142 355 A1 discloses a washing machine with an attachment for commercial detergent bottles, which allows a filling of the dispenser with liquid detergent, wherein a predetermined amount of detergent can be filled. The disadvantage of this solution is that no reservoirs are provided in the washing machine. Instead, the detergent bottles for each wash must be placed on the essay. The disclosed fill level indicator for the dispenser bowl thus provides no information about the remaining detergent supply, but is only about the amount of a single dose of detergent. The invention has the object of providing a washing machine described above in such a way that the monitoring of emptying of reservoirs for the user is simplified in such a way that he does not have to raise the drawer of Waschmitteleinspüleinrichtung to read a deficiency in the reservoir.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine automatisch gesteuerte Waschmaschine mit einer im Maschinenraum frontseitig angeordneten Einspüleinrichtung für Wäschebehandlungsmittel, umfassend eine von vorn zugängliche Schublade mit mindestens einem Vorratsbehälter für einen mehrere Dosen umfassenden Vorrat an flüssigem oder gelförmigem Wäschebehandlungsmittel und eine an der Schublade fest verbundene Handhabe zum Aufziehen und Einschieben der Schublade, dadurch gekennzeichnet, dass der Vorratsbehälter hinter der Handhabe eine zumindest durchscheinende Wand aufweist und die Handhabe vor jedem unmittelbar dahinter angeordneten Vorratsbehälter in der Schublade eine sich vertikal erstreckende, fensterartige Ausnehmung aufweist. According to the invention, this object is achieved by an automatically controlled washing machine with a front in the machine room arranged washing-up for laundry treatment comprising a drawer accessible from the front with at least one reservoir for a multi-dose supply of liquid or gel laundry aid and a firmly attached to the drawer handle for Mounting and inserting the drawer, characterized in that the reservoir behind the handle has an at least translucent wall and the handle in front of each immediately behind arranged reservoir in the drawer has a vertically extending, window-like recess.
Dadurch ist hinter jeder Ausnehmung der Vorratsbehälter und durch seine zumindest durchscheinende Wand hindurch der Füllstand des Vorratsbehälters mit Wäschebehandlungsmittel erkennbar, ohne dass die Schublade aufgezogen werden muss. As a result, behind each recess of the reservoir and through its at least translucent wall through the level of the reservoir with laundry treatment means recognizable without the drawer must be raised.
Vorteilhafterweise weist der Vorratsbehälter einen transparenten oder transluzenten Bereich auf, der hinter der Ausnehmung positioniert ist. Die Beobachtung ist nämlich bereits dann möglich, wenn der Bereich des Vorratsbehälters unmittelbar hinter der Ausnehmung transparent oder transluzent ausgebildet ist. Es hilft der Erkennbarkeit des Füllzustandes erheblich, wenn gemäß einer weiteren Ausbildung der Erfindung die der Ausnehmung nahe stehende Wand des Vorratsbehälters hinterleuchtet oder angeleuchtet ist. Advantageously, the storage container has a transparent or translucent region, which is positioned behind the recess. The observation is namely already possible if the region of the reservoir is formed directly behind the recess transparent or translucent. It helps the recognizability of the filling state considerably, if, according to a further embodiment of the invention, the recess of the near-standing wall of the reservoir is backlit or illuminated.
In technisch leicht zu realisierender Weise kann eine solche Be- oder Hinterleuchtung durch eine vorteilhafte Fortbildung der Erfindung gestaltet sein, wenn die der Ausnehmung nahe stehende Wand zwischen einer gegenüber dem Vorratsbehälter ortsfesten Lichtquelle und der Ausnehmung eine Licht leitende Struktur aufweist. Eine solche Licht leitende Struktur kann bei der Herstellung des Vorratsbehälters aus einem transparenten Material bereits berücksichtigt werden. In technically easy to implement manner such illumination or backlighting can be designed by an advantageous development of the invention, when the wall close to the recess between a relative to the reservoir stationary light source and the recess has a light-conducting structure. A Such a light-conducting structure can already be taken into account in the manufacture of the reservoir from a transparent material.
Dabei kann die Lichtquelle an der Schublade oder an einem im Maschinenraum befestigten Ort befestigt sein. In this case, the light source may be attached to the drawer or to a location fixed in the machine room.
Besonders vorteilhaft ist es, wenn die der Ausnehmung nahe stehende Wand des Vorratsbehälters transparent oder transluzent ausgebildet ist und mit einer linienförmigen Auswölbung bis in die Ausnehmung hinein reicht. Dann ist die Sichtfläche des Vorratsbehälters, von dem der Füllzustand unmittelbar abgelesen werden kann, dem Betrachter in die nächstmögliche Position gerückt. It is particularly advantageous if the wall of the storage container which is close to the recess is transparent or translucent and extends into the recess with a line-shaped bulge. Then the visible surface of the reservoir, from which the filling state can be read directly, moved the viewer in the next possible position.
Alternativ dazu können aber auch die Ausnehmungen mit einer transparenten oder transluzenten Einlage versehen sein und die Vorratsbehälter von innen dicht an der Einlage anliegen. Dabei wird das Bild des Füllzustands unmittelbar über die Einlage an die Außenfläche der Handhabe getragen und sehr gut erkennbar. Dies wird dann noch erheblich verstärkt, wenn die transparente oder transluzente Einlage an ihrer äußeren Sichtfläche und/oder an ihrer zum Vorratsbehälter gewandten Fläche parallel zu ihrer Höhenerstreckung konvex geformt ist. Die Merkmale der Unteransprüche können auf jede sinnvolle Weise mit denen des Hauptanspruches und untereinander kombiniert werden, ohne den Erfindungsgedanken zu verlassen. Alternatively, however, the recesses may also be provided with a transparent or translucent insert and the reservoirs bear against the insert from the inside. The image of the filling state is carried directly over the insert to the outer surface of the handle and very easily recognizable. This is then considerably enhanced if the transparent or translucent insert is convexly formed on its outer visible surface and / or on its surface facing the reservoir parallel to its vertical extent. The features of the subclaims can be combined in any meaningful way with those of the main claim and with each other, without departing from the inventive concept.

Innerhalb des Gehäuses 1 der Waschmaschine in Fig. 1 ist mit gestrichelter Linie ein schwingend eingehängtes Laugenbehälteraggregat 2 angedeutet, dessen zentrale Öffnung durch eine Fronttür 3 verschließbar ist. Die oben an der Frontseite 1.1 (Fig. 2) angebaute Bedienungsblende 4 enthält Armaturen 5 und ein Anzeigedisplay 6 zum Einstellen von Programmen, die von einer Programmsteuereinrichtung 7 ausgegeben werden können und zur Steuerung der maschinellen Vorgänge, auch denen der automatischen Dosierung von Wäschebehandlungsmitteln, dienen. Within the housing 1 of the washing machine in Fig. 1 is indicated by a dashed line a swinging hooked tub unit 2, the central opening is closed by a front door 3. The control panel 4 mounted on the front side 1.1 (Fig. 2) includes faucets 5 and a display panel 6 for setting programs which can be outputted from a program controller 7 and for controlling the automatic operations, including automatic dosing of laundry treating means ,
In der oberen linken Raumecke des Gehäuses 1 ist in üblicher Weise eine Waschmitteleinspüleinrichtung 8 angeordnet, die eine aus der entsprechenden Gehäusehöhle heraus ziehbare Schublade 9 enthält. An der Frontseite der Schublade 9 ist als Handhabe eine Griffplatte 10 angebracht, die bei in die Gehäusehöhle voll eingeschobener Schublade 9 außenbündig zu der Bedienungsblende 4 steht. Durch gestrichelte Linien ist erkennbar, dass hinter der Griffplatte 10 Vorratsbehälter 16 bis 18 in der Schublade 9 angeordnet sind. In die Griffplatte 10 sind Ausnehmungen 22 bis 24 eingearbeitet, durch die hindurch der Betrachter auf die vorderen Wände der Vorratsbehälter 16 bis 18 schauen kann. Diese Wände sind mindestens im Deckungsbereich zu den Ausnehmungen 22 bis 24 transparent oder transluzent, so dass der Füllzustand der Vorratsbehälter 16 bis 18 optisch erfasst werden kann. An den oder in der Nähe der Ausnehmungen 22 bis 24 können Skalierungen für den jeweiligen Füllzustand angebracht sein. Ein Ausführungsbeispiel einer Schublade gemäß der Erfindung zeigt Fig. 2. Darin nimmt die Waschmitteleinspüleinrichtung 8 - wie im angegebenen Stand der Technik - die gesamte Tiefe des Maschinengehäuses 1 ein. Die unter einer zur Zuführung von Frischwasser dienenden Deckplatte gemäß Pfeil 19 schiebbeweglich angeordnete Schublade 9 ist mit der frontseitigen Griffplatte 10 fest verbunden und enthält zwei Behälter 11 und 12, von denen der Behälter 1 1 für eine Einzeldosis von pulverförmigem Wäschebehandlungsmittel vorgesehen ist und der Behälter 12 für eine Einzeldosis von flüssigem Wäschebehandlungsmittel. Damit die Flüssigkeit beim Befüllen des Behälters 12 mit Wasser aus dem Behälter abfließen kann, ist ein notorischer Saugheber 13 im Behälter 12 angeordnet. Zum Ausspülen des Behälters 11 hat dieser einen seitlichen Auslass (hier nicht näher dargestellt), der den Inhalt des Behälters auf einen Boden der Gehäuseschale entlässt, mit der die Waschmitteleinspüleinrichtung 8 umgeben ist. In the upper left corner of the housing 1, a Waschmitteleinspüleinrichtung 8 is arranged in a conventional manner, which includes a pull-out of the corresponding housing cavity drawer 9. At the front of the drawer 9, a handle plate 10 is attached as a handle, which is flush with the fully inserted into the housing cavity drawer 9 to the control panel 4. By dashed lines can be seen that behind the handle plate 10 reservoir 16 to 18 are arranged in the drawer 9. In the handle plate 10 recesses 22 to 24 are incorporated, through which the viewer can look at the front walls of the reservoir 16 to 18. These walls are transparent or translucent at least in the area of coverage to the recesses 22 to 24, so that the filling state of the storage containers 16 to 18 can be optically detected. At or near the recesses 22 to 24, scalings may be made for the particular fill condition. An embodiment of a drawer according to the invention is shown in FIG. 2. Therein, the detergent dispensing device 8 - as in the cited prior art - occupies the entire depth of the machine housing 1. Under a serving for supplying fresh water cover plate according to arrow 19 slidingly arranged drawer 9 is fixedly connected to the front side handle plate 10 and contains two containers 11 and 12, of which the container 1 1 is provided for a single dose of powdered laundry treatment agent and the container 12th for a single dose of liquid laundry treatment. So that the liquid can flow out of the container during the filling of the container 12 with water, a notorious siphon 13 is arranged in the container 12. For rinsing out the container 11, this has a lateral outlet (not shown here in detail), which discharges the contents of the container onto a bottom of the housing shell, with which the detergent dispensing device 8 is surrounded.
Hinter dem Behälter 1 1 ist eine Magnetventilgruppe 14 angeordnet, die vom Netzanschlussstutzen 15 an der Rückwand 1.2 des Gehäuses 1 zugeführtes Wasser in die Behälter 1 1 und 12 führt. Ausgespültes Wäschebehandlungsmittel wird über nicht dargestellte Leitungen in den Laugenbehälter 2 überführt. Behind the container 1 1, a solenoid valve group 14 is arranged, which leads from the mains connection piece 15 to the rear wall 1.2 of the housing 1 supplied water into the container 1 1 and 12. Rinsed laundry treatment agent is transferred via lines not shown in the tub 2.
Entlang der rechten Längsseite der Schublade 9 und in ihrem vorderen Bereich sind Vorratsbehälter 16, 17 und 18 in der Schublade 9 angeordnet, die rundherum geschlossen sind bis auf eine Ausnahme: im vorderen Bereich hat jeder Vorratsbehälter 16 bis 18 in seiner Deckfläche eine Nachfüllöffnung 20, die mittels eines Schiebers 21 verschlossen bzw. geöffnet werden kann. In Fig. 3 ist eine anders ausgestattete Schublade 9 nach ihrer Entnahme aus der Gehäusehöhle in einer Ansicht von oben dargestellt, die ausschließlich Vorratsbehälter 25 bis 27 für einen mehrere Dosen umfassenden Vorrat an flüssigem bzw. gelförmigem Wäschebehandlungsmittel enthalten. Jeder dieser Vorratsbehälter 25 bis 27 ist in einen Aufnahmeraum 28 der Schublade eingesetzt und kann gegen einen anderen hier hineinpassenden Vorratsbehälter ausgetauscht werden. Dies geschieht vor allem immer dann, wenn einer der Vorratsbehälter 25 bis 27 (oder 16 bis 18 der Fig. 2, wenn diese nicht nachfüllbar ausgestaltet sind) entleert worden ist. Die eingesetzten Vorratsbehälter 25 bis 27 legen sich mit ihren vorderen Wänden 29 dicht an die Rückseite der Griffplatte 10 an, und zwar so, dass sich der transparente oder transluzente Bereich der Wand 29 genau mit der jeweiligen Ausnehmung 30, 31 , oder 32 deckt. Dadurch wird dieser Bereich durch die jeweilige Ausnehmung hindurch sichtbar und zeigt den Füllzustand des zugehörigen Vorratsbehälters an. Along the right longitudinal side of the drawer 9 and in its front region storage containers 16, 17 and 18 are arranged in the drawer 9, which are closed all around except for one exception: in the front region each reservoir has 16 to 18 in its top surface a refill 20, which can be closed or opened by means of a slide 21. In Fig. 3, a differently equipped drawer 9 is shown after its removal from the housing cavity in a view from above, containing only reservoir 25 to 27 for a multi-dose supply of liquid or gel laundry treatment agent. Each of these reservoirs 25 to 27 is inserted into a receiving space 28 of the drawer and can be exchanged for another in this fitting reservoir. This happens above all whenever one of the storage containers 25 to 27 (or 16 to 18 of FIG. 2, if they are not designed to be refillable) has been emptied. The storage containers used 25 to 27 lie with their front walls 29 tight against the back of the handle plate 10, in such a way that the transparent or translucent portion of the wall 29 coincides exactly with the respective recess 30, 31, or 32. This will make this area visible through the respective recess and indicates the filling state of the associated storage container.
Für die Einzelheit E sind in Fig. 4 bis 7 weitere, vom Beispiel der Fig. 3 abweichende Varianten dargestellt. So zeigt Fig. 4 eine Variante, bei der die Vorderwand 29 des Vorratsbehälters 25 in Höhe der Ausnehmung 30 unmittelbar an der Rückseite der Griffplatte 10 anliegt. In die Vorderwand 29 ist aber auch ein Lichtleiter 33 integriert, dessen Lichteintrittsfläche 34 gegen eine Lichtquelle 35 gerichtet ist, die mit der Griffplatte 10 verbunden ist. Der Lichtleiter 33 ist mit einem transluzenten Bereich 36 der Vorderwand 29 des Vorratsbehälters 25 optisch verbunden, so dass das von der Lichtquelle 35 ausgehende Licht durch den Lichtleiter 33 in den transluzenten Bereich 36 eingestrahlt wird. Der transluzente Bereich 36 erstreckt sich über die Höhe der Vorderwand 29 entlang der Ausnehmung 30. Durch die seitliche Einstrahlung aus der Lichtquelle 35 hebt sich der transluzente Bereich 36 stark von seiner Umgebung ab; denn er ist in den aus dem Vorratsbehälter 25 mit Wäschebehandlungsmittel benetzten Bereichen dunkler als in den unbenetzten Bereichen. Dadurch ergibt sich wie in Fig. 1 ein gut erkennbarer senkrechter Balken (z. B. dort an der Ausnehmung 22) als analoges Maß für den Füllzustand des zugehörigen Vorratsbehälters. Die Vorderwand 37 des Vorratsbehälters 38 in Fig. 5 ist über die Höhe der Ausnehmung 30 in ihren Hohlraum eingeformt, so dass zwischen der Ausnehmung 30 und der Einformung 39 ein Formschluss entsteht. So kann von seitlich auf die Außenfläche der Vorderwand 37 des Vorratsbehälters 38 einfallendes Licht ferngehalten werden. Der Lichtleiter 40 entnimmt in diesem Beispiel das Licht aus einer Lichtquelle 41 , die hier an einem fest stehenden Teil der Waschmitteleinspüleinrichtung 8 angebracht ist. Entsprechend ist die Lichteintrittsfläche 42 des Lichtleiters 40 zur Seite gewandt. Der Lichtleiter 40 hat im Überdeckungsbereich mit der Ausnehmung 30 eine opake Fläche 43, z. B. durch Anrauung, die unmittelbar in den Vorratsbehälterinnenraum reicht, so dass sie von Wäschebehandlungsmittel benetzt wird. Im Bereich der Benetzung erscheint dann die opake Fläche 43 deutlich dunkler als ihre Umgebung und ist durch die Ausnehmung hindurch sehr gut erkennbar. For the detail E are shown in Fig. 4 to 7 further, different from the example of FIG. 3 variants. Thus, Fig. 4 shows a variant in which the front wall 29 of the reservoir 25 at the level of the recess 30 rests directly on the back of the handle plate 10. In the front wall 29 but also a light guide 33 is integrated, the light inlet surface 34 is directed against a light source 35 which is connected to the handle plate 10. The light guide 33 is optically connected to a translucent region 36 of the front wall 29 of the storage container 25, so that the light emitted by the light source 35 is radiated through the light guide 33 into the translucent region 36. The translucent region 36 extends over the height of the front wall 29 along the recess 30. Due to the lateral irradiation from the light source 35, the translucent region 36 stands out sharply from its surroundings; because he is darker in the wetted from the reservoir 25 with laundry treatment areas as in the unwetted areas. As a result, as can be seen in Fig. 1, an easily recognizable vertical beam (for example, at the recess 22) results as an analogous measure of the filling state of the associated storage container. The front wall 37 of the reservoir 38 in Fig. 5 is formed over the height of the recess 30 in its cavity, so that between the recess 30 and the indentation 39 creates a positive connection. Thus, from the side of the outer surface of the front wall 37 of the reservoir 38 incident light can be kept away. The light guide 40 takes in this example, the light from a light source 41, which is attached here to a fixed part of Waschmitteleinspüleinrichtung 8. Accordingly, the light entrance surface 42 of the light guide 40 is turned to the side. The light guide 40 has in the overlap region with the recess 30 an opaque surface 43, z. B. by Anrauung that extends directly into the reservoir interior, so that it is wetted by laundry treatment agent. In the area of wetting, the opaque area 43 then appears much darker than its surroundings and is very easily recognizable through the recess.
Der Formschluss zwischen der Ausnehmung 44 der Griffplatte 10 und einer EinformungThe positive connection between the recess 44 of the handle plate 10 and a molding
45 der Vorderwand 46 des Vorratsbehälters 47 in Fig. 6 ist noch ausgeprägter als bei der Vorderwand 37 in Fig. 5. Hier reicht die Einformung 45 bis in die Flucht der Frontfläche der Griffplatte 10, so dass auch im Vorratsbehälter 47 befindliches Wäschebehandlungsmittel bis hierhin fließt. Seine dunklere Färbung tritt daher unmittelbar an der Frontfläche der Griffplatte 10 in Erscheinung. Sie bildet gegen die nicht benetzte Einformung 45 der Vorderwand 46 im Umgebungslicht eine stark kontrastierende Fläche, die nicht zu übersehen ist. Zusätzlich kann auch hier bei Bedarf eine Lichtquelle 48 unterhalb oder oberhalb der Einformung 45 in den Vorratsbehälter 47 strahlen, um den Effekt gegebenenfalls zu verstärken. Diese Lichtquelle 48 kann nach Wahl des Konstrukteurs an der Griffplatte 10, anderweitig an der Schublade 9 oder völlig feststehend an der die Schublade 9 umgebenden Gehäusehöhle angebracht sein. 45 of the front wall 46 of the reservoir 47 in Fig. 6 is even more pronounced than in the front wall 37 in Fig. 5. Here, the indentation 45 extends into the alignment of the front surface the handle plate 10 so that also located in the reservoir 47 laundry treatment agent flows to this point. Its darker color therefore occurs directly on the front surface of the handle plate 10 in appearance. It forms against the non-wetted indentation 45 of the front wall 46 in the ambient light a strongly contrasting surface, which is not overlooked. In addition, a light source 48 below or above the indentation 45 can radiate into the reservoir 47, if necessary, in order to enhance the effect if necessary. This light source 48 may be attached at the choice of the designer to the handle plate 10, otherwise to the drawer 9 or completely fixed to the drawer 9 surrounding the housing cavity.
Die Griffplatte 10 in Fig. 7 hat zwar ebenfalls eine Ausnehmung; sie ist aber mit einer transparenten oder transluzenten Einlage 49 ausgefüllt, an der von ihrer Innenseite her die Vorderwand 50 des Vorratsbehälters 51 anliegt. Im Bereich dieser Einlage 49 hat die Vorderwand 50 des Vorratsbehälters 51 einen Licht leitenden Abschnitt 52, in den von untern oder oben her das Licht einer Lichtquelle 53 einstrahlt. Although the handle plate 10 in Fig. 7 also has a recess; but it is filled with a transparent or translucent insert 49, against which the front wall 50 of the reservoir 51 rests from its inside. In the region of this insert 49, the front wall 50 of the storage container 51 has a light-conducting section 52 into which the light from a light source 53 radiates from below or above.
Die Einlage 49 ist an ihrer Sichtfläche 54 parallel zur Höhenerstreckung der Ausnehmung konvex geformt, um mit dem dadurch entstehenden Lupeneffekt die Abbildung der Füllhöhe im Licht leitenden Abschnitt 52 zu vergrößern. Eine ähnliche Formung kann auch die zum Vorratsbehälter 51 gewandte Fläche haben. The insert 49 is convexly formed on its visible surface 54 parallel to the vertical extent of the recess in order to increase the image of the filling height in the light-conducting section 52 with the resulting magnifying effect. A similar shaping can also have the surface facing the reservoir 51.
Es ist ohne Weiteres ersichtlich, dass einzelne Merkmale aus den Beispielen der Fig. 1 bis 7 auch jeweils - wo zweckmäßig - in den anderen Beispielen angewendet werden können, ohne damit den Erfindungsgedanken zu verlassen. Beispielweise kann die Einformung 45 der Fig. 6 mit einer transparenten oder transluzenten Einlage 49 gemäß Fig. 7 gefüllt sein und eine konvexe Sichtfläche haben. Alle Beispiele können mit oder ohne Verwendung von Fremdlicht durch eine Lichtquelle kombiniert werden, deren Licht unmittelbar mit der Füllstand-Sichtfläche zusammenwirkt oder mittelbar über einen Lichtleiter mit oder ohne opaker Lichtaustrittsfläche. It is readily apparent that individual features of the examples of Figs. 1 to 7, respectively - where appropriate - can be applied in the other examples, without departing from the spirit of the invention. For example, the indentation 45 of FIG. 6 may be filled with a transparent or translucent insert 49 according to FIG. 7 and have a convex visible surface. All examples can be combined with or without the use of extraneous light by a light source whose light interacts directly with the level visual surface or indirectly via a light guide with or without opaque light exit surface.
