Description

Haushaltgerät sowie Home appliance as well
Schalter zur Verwendung in einem HaushaltgerätSwitches for use in a household appliance
Die Erfindung betrifft ein Haushaltgerät mit einer um eine horizontal verlaufende Achse schwenkbar gelagerten Tür sowie einen Schalter zur Verwendung in einem solchen Haushaltgerät.The invention relates to a household appliance with a door pivotably mounted about a horizontally extending axis and a switch for use in such a household appliance.
Bekannt sind z.b. Geschirrspülmaschinen oder Herde mit einer um eine horizontal verlaufende Achse schwenkbar gelagerten Tür, die zum Be- und Entladen geöffnet wird. Üblicherweise ist diese schwenkbar gelagerte Tür bei einer Geschirrspülmaschine so ausge- bildet, dass sie zum Be- und Entladen soweit geöffnet wird, dass die dem Behandlungsraum, dem Spülbehälter, zugewandte Innenseite der Tür im wesentlichen waagrecht ausgerichtet ist, um einen unteren Geschirrkorb aufnehmen zu können. Zu diesem Zweck weist der untere Geschirrkorb vorteilhafterweise Rollen oder Radvorrichtungen an seiner Unterseite auf, die über spezielle Schienen oder Sicken in der Türinnenseite geführt wer- den. Nach dem vollständigen Aufklappen der Tür, d.h. bis die Tür im wesentlichen horizontal ausgerichtet ist und dem Herausrollen des unteren Geschirrkorbs kann dieser relativ bequem Be- und Entladen werden. Eine so weit geöffnete Tür stellt ein gewisses Gefahrenpotential dar, insbesondere, wenn sich eine so geöffnete Geschirrspülmaschine in einem dunklen Raum, beispielsweise einer Küche, befindet.For example, Dishwashers or cookers with a door pivoted about a horizontal axis that is opened for loading and unloading. This pivotally mounted door is usually designed in a dishwasher in such a way that it is opened for loading and unloading to such an extent that the inside of the door facing the treatment room, the washing compartment, is aligned substantially horizontally in order to be able to accommodate a lower dish basket , For this purpose, the lower crockery basket advantageously has rollers or wheel devices on its underside, which are guided over special rails or beads in the inside of the door. After fully opening the door, i.e. until the door is aligned substantially horizontally and rolling out the lower basket can be loaded and unloaded relatively easily. A door opened so far represents a certain risk potential, in particular if a dishwasher opened in this way is located in a dark room, for example a kitchen.
Aus der DE 198 04 894 A1 ist ein Schalter bekannt, der bei Haushaltgeräten, beispielsweise bei Geschirrspülmaschinen, verwendet werden kann und so an dem Haushaltgerät angeordnet ist, dass bei geöffneter Tür eine Lichtquelle im Inneren des Haushaltgeräts angeschaltet wird, die beim Schließen der Tür wieder erlischt. Zum Betätigen des Schal- ters ist eine Schaltnocke vorgesehen, der ein Federelement zugeordnet ist und der Schalter über einen Schaltstößel verfügt, der von dem Federelement betätigbar ist. Mit diesem Schalter ist es möglich, lediglich zwischen den beiden Zuständen „Tür geschlossen" und „Tür geöffnet" zu unterscheiden. Von Nachteil ist, dass ein Zwischenzustand, wie beispielsweise „Tür leicht geöffnet" nicht erkannt wird. Ein Erkennen dieses Zwischenzu- Stands wäre indes bei frontseitig beschickbaren Geschirrsmaschinen wünschenswert, um sowohl den unterschiedlichen Angewohnheiten der Benutzer als auch dem Wunsch nach Hinweis auf ein Gefahrenpotential zu entsprechen. Der Erfindung liegt daher die Aufgabe zugrunde, ein Haushaltgerät der eingangs genannten Art zu schaffen, das auch bei weit geöffneter Tür kein erhöhtes Gefahrenpotential darstellt, sowie ferner einen Schalter bereitzustellen, der auch Zwischenzustände der Türposition „erkennt".From DE 198 04 894 A1 a switch is known which can be used in household appliances, for example in dishwashers, and is arranged on the household appliance in such a way that when the door is open a light source inside the household appliance is switched on, which is switched on again when the door is closed goes out. A switch cam is provided for actuating the switch, to which a spring element is assigned and the switch has a switch plunger which can be actuated by the spring element. With this switch it is possible to differentiate only between the two states "door closed" and "door open". It is disadvantageous that an intermediate state, such as “door slightly opened”, is not recognized. Recognizing this intermediate state would, however, be desirable for dishwashers that can be loaded from the front, in order to address both the different habits of the users and the desire to indicate a potential hazard correspond. The object of the invention is therefore to create a household appliance of the type mentioned at the outset which does not represent an increased risk potential even when the door is wide open, and also to provide a switch which also “detects” intermediate states of the door position.
Diese Aufgabe wird durch das erfindungsgemäße Haushaltgerät mit den Merkmalen des Anspruchs 1 sowie durch den erfindungsgemäßen Schalter mit den Merkmalen des weiteren unabhängigen Anspruchs gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.This object is achieved by the household appliance according to the invention with the features of claim 1 and by the switch according to the invention with the features of the further independent claim. Advantageous embodiments of the invention are characterized in the subclaims.
Das erfindungsgemäße Haushaltgerät mit einer um eine horizontal verlaufende Achse schwenkbar gelagerten Tür weist einen Schalter auf, der so in der Tür angeordnet und ausgebildet ist, dass er bei Erreichen eines bestimmten Schwenkwinkels der nicht geschlossenen Tür eine Lichtquelle im Inneren des Haushaltgeräts anschaltet.The household appliance according to the invention with a door pivotably mounted about a horizontally extending axis has a switch which is arranged and designed in the door such that it switches on a light source inside the household appliance when a certain pivoting angle of the non-closed door is reached.
Der erfindungsgemäße Schalter weist eine versenkbare Taste auf, die mittels eines Gewichts, welches sich stets selbst zur Vertikalen ausrichtet, betätigbar ist. Dadurch wird ab einer gewissen Neigung der Tür ein Stromkreis geschlossen, um eine Lichtquelle im Inneren des Haushaltgeräts anzuschalten.The switch according to the invention has a retractable button which can be actuated by means of a weight which always aligns itself with the vertical. As a result, a circuit is closed from a certain inclination of the door in order to switch on a light source inside the household appliance.
Beim täglichen Gebrauch eines Haushaltgeräts mit einer um eine horizontal verlaufenden Achse schwenkbar gelagerten Tür wird dieser gemäß den persönlichen Angewohnheiten des Benutzers unterschiedlich verwendet. Während einige Benutzer die schwenkbar gelagerte Tür stets geschlossen halten und lediglich zum Be- und Entladen öffnen, verriegeln andere Personen die schwenkbar gelagerte Tür lediglich während des Programmab- laufs und lassen in der übrigen Zeit die Tür unverriegelt angelehnt. Auch wenn die mechanische Verriegelungsanlage und die Türdichtungen heutiger Haushaltgeräte durchaus für eine Belastung auf Lebenszeit ausgelegt ist, vermeiden einige Personen das stetige Verriegeln der Tür wenn kein Programm läuft. Ein anderer Grund für das Nichtverriegeln kann sein, dass sich die Tür zum Beladen schneller öffnen lässt, wenn sie nicht verriegelt ist. Ein weiterer Grund für das Nichtverriegeln kann sein, dass Gerüche entweichen können. Auch kann Feuchtigkeit leicht aus dem Innern des Haushaltgeräts entweichen, ohne dass die Tür soweit aufgeschwenkt ist, dass sie ein Gefahrenpotential darstellt. Mit dem erfindungsgemäßen Schalter in einem Haushaltgerät mit einer um eine horizontale verlaufende Achse schwenkbar gelagerten Tür ist es möglich, erst bei Erreichen eines bestimmten Schwenkwinkels der nicht geschlossenen Tür eine Lichtquelle im Inneren des Haushaltgeräts anzuschalten, die den Innenraum des Haushaltgeräts ausleuchtet. Somit ist es mit dem Haushaltgerät auch möglich, gemäß den persönlichen Angewohnheiten des Benutzers, die Tür angelehnt zu lassen, ohne dass eine Lichtquelle angeschaltet wird.In daily use of a household appliance with a door pivoted about a horizontal axis, this is used differently according to the personal habits of the user. While some users always keep the swivel-mounted door closed and only open it for loading and unloading, other people only lock the swivel-mounted door while the program is running and leave the door unlocked for the rest of the time. Even if the mechanical locking system and the door seals of today's household appliances are designed to last for a lifetime, some people avoid constantly locking the door when no program is running. Another reason for not being locked can be that the door can be opened for loading more quickly if it is not locked. Another reason for not locking can be that odors can escape. Moisture can also easily escape from the interior of the household appliance without the door being swung open to such an extent that it represents a potential hazard. With the switch according to the invention in a household appliance with a door pivotally mounted about a horizontal axis, it is possible to switch on a light source inside the household appliance which illuminates the interior of the household appliance only when a certain pivoting angle of the non-closed door is reached. It is therefore also possible with the household appliance to leave the door ajar in accordance with the personal habits of the user, without switching on a light source.
Ein mit dem erfindungsgemäßen Schalter ausgestattetes erfindungsgemäßes Haushaltgerät weist somit den Vorteil auf, dass eine Lichtquelle immer dann angeschaltet wird, wenn die Tür soweit aufgeschwenkt ist, dass sie eine potentielle Gefahrenquelle darstellen kann, jedoch bei einem geringen Schwenkwinkel der Tür kein Licht eingeschaltet wird. Ein weiterer Vorteil der vorliegenden Erfindung liegt darin, dass der Benutzer des Haushaltgeräts, der beispielsweise ein in das Haushaltgerät einzufüllendes Gut tragend die unbeleuchtete Küche betritt, zum Beladen des Haushaltgeräts nicht eigens hierfür das Raumlicht einschalten muß, sondern lediglich nach Abstellen des Guts und Öffnen des Haushaltgeräts ausreichend Licht hat, um das Haushaltgerät beladen zu können.A household appliance according to the invention equipped with the switch according to the invention thus has the advantage that a light source is always switched on when the door is swung open to the extent that it can represent a potential source of danger, but no light is switched on when the door is pivoted at a small angle. Another advantage of the present invention is that the user of the household appliance, who enters the unlit kitchen, for example, carrying a good to be filled into the household appliance, does not have to switch on the room light specifically for loading the household appliance, but only after the goods have been switched off and opened Household appliance has sufficient light to be able to load the household appliance.
Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Schalters ist über der versenkbaren Taste ein bandartiger Riegel so angeordnet, dass das an dessen Ende vor- gesehene Gewicht aufgrund der Schwerkraft die versenkbare Taste ab einer bestimmbaren Neigung niederdrückt und so einen Stromkreis schließt, der eine Lichtquelle einschaltet. Wird der Schwenkwinkel der geöffneten Tür verringert, so senkt sich entsprechend die Auflagekraft des bandartigen Riegels auf die unter Federdruck stehende Taste. Sobald der Federdruck in der Taste größer ist als die Auflagekraft des bandartigen Riegels drückt die Feder die Taste von der Kontaktstelle weg und der Stromkreis zur Lichtquelle ist unterbrochen. Gemäß einfachen physikalischen Beziehungen, deren Rechengrößen die Federstärke in der Taste, die Masse des Gewichts und der geometrische Verlauf des Verbindungsmittels sind, lässt sich der Neigungswinkel berechnen, ab dem die Schalterfunktion ausgelöst wird. Durch eine Änderung dieser Größen kann der Neigungswinkel eingestellt werden.In a preferred embodiment of the switch according to the invention, a band-like latch is arranged above the retractable button in such a way that the weight provided at the end of the switch depresses the retractable button due to the force of gravity above a determinable inclination and thus closes a circuit which switches on a light source. If the pivoting angle of the opened door is reduced, the contact force of the band-like bolt on the button under spring pressure is reduced accordingly. As soon as the spring pressure in the button is greater than the contact force of the band-like bolt, the spring pushes the button away from the contact point and the circuit to the light source is interrupted. The angle of inclination from which the switch function is triggered can be calculated in accordance with simple physical relationships, the arithmetic parameters of which are the spring strength in the key, the mass of the weight and the geometric course of the connecting means. The angle of inclination can be adjusted by changing these sizes.
Nach einer vorteilhaften Ausführungsform der Erfindung wird durch eine ösenartige Ausnehmung in der versenkbaren Taste ein forminstabiles Verbindungsmittel geführt, an des- sen Ende ein Gewicht vorgesehen ist, welches aufgrund der Schwerkraft die versenkbare Taste niederdrückt. Das forminstabile Verbindungsmittel kann hierbei aus einem Draht und/oder Kunststoff bestehen.According to an advantageous embodiment of the invention, an unstable connecting means is guided through an eyelet-like recess in the retractable button, on which A weight is provided at the end which depresses the retractable button due to gravity. The dimensionally unstable connecting means can consist of a wire and / or plastic.
Mit der Erfindung ist ein Haushaltgerät mit einer um eine horizontal verlaufende Achse schwenkbar gelagerten Tür geschaffen, das auch bei weit geöffneter Tür kein erhöhtes Gefahrenpotential darstellt, sowie ferner ein Schalter bereitgestellt, der auch Zwischenzustände der Türposition „erkennt".The invention provides a household appliance with a door pivotably mounted about a horizontally extending axis, which does not represent an increased hazard potential even when the door is wide open, and also a switch which also "detects" intermediate states of the door position.

In Figur 1 wird ein erfindungsgemäßes Haushaltgerät, im Ausführungsbeispiel eine Ge- schirrspülmaschine 1 , gezeigt, auf deren um eine horizontal verlaufende, nicht dargestellten Achse schwenkbar gelagerten Tür 2 ein Geschirrkorb 3 angeordnet ist. In diesem Zustand ist ein Schalter 4 aktiviert und hat eine Lichtquelle 5, die im Innenraum 6 der Geschirrspülmaschine 1 angeordnet ist, eingeschaltet. Der Schalter 4 kann auch mit einer Steuereinheit 7 verbunden sein, die ihrerseits mit der Lichtquelle 5 verbunden ist und de- ren Zustand steuert. Die Steuereinheit 7 ist zweckmäßigerweise mit der elektronischen Programmsteuerung, im gezeigten Ausführungsbeispiel einem Programmsteuergerät, der Geschirrspülmaschine 1 verbunden. In Figur 2 ist die Geschirrspülmaschine 1 gezeigt, deren schwenkbare Tür 2 so geneigt ist, dass der Schalter 4 nicht aktiviert dargestellt ist. In dieser Stellung kann Wasserdampf leicht aus dem Innern der Geschirrspülmaschine entweichen, ohne dass jedoch die Tür 2 soweit aufgeschwenkt ist, dass sie ein Gefahrenpotential darstellt.FIG. 1 shows a household appliance according to the invention, in the exemplary embodiment a dishwasher 1, on the door 2 of which a dish rack 3 is arranged on a door 2 that is pivotable about a horizontally extending axis (not shown). In this state, a switch 4 is activated and has switched on a light source 5, which is arranged in the interior 6 of the dishwasher 1. The switch 4 can also be connected to a control unit 7, which in turn is connected to the light source 5 and controls its state. The control unit 7 is expediently connected to the electronic program control, in the exemplary embodiment shown a program control device, of the dishwasher 1. FIG. 2 shows the dishwasher 1, the pivotable door 2 of which is inclined so that the switch 4 is not shown activated. In this position, water vapor can easily escape from the inside of the dishwasher, but without the door 2 being swung open to such an extent that it represents a potential hazard.
In Figur 3 ist eine schematische Darstellung des erfindungsgemäßen Schalters 4 gezeigt mit einer Taste 8, die über eine Feder 11 vorgespannt ist. In dieser ersten Lage hängt das Gewicht 10 an einem forminstabilen Verbindungsmittel 9, beispielsweise einem Draht oder Kunststoffband. Das Verbindungsmittel kann ebenso formstabil ausgebildet sein, wobei jedoch die relative Bewegung des Verbindungsmittels gegenüber der Taste be- rücksichtigt werden muss, Durch die Schwerkraft bedingt, übt das Gewicht 10 eine gewisse Kraft auf die Taste 8 aus, wobei jedoch in diesem Zustand die Federkraft größer ist und der Schalter 4 in der „Aus" Stellung verbleibt.FIG. 3 shows a schematic illustration of the switch 4 according to the invention with a button 8 which is biased by a spring 11. In this first position, the weight 10 hangs on a dimensionally unstable connecting means 9, for example a wire or plastic tape. The connecting means can also be designed to be dimensionally stable, but the relative movement of the connecting means with respect to the key must be taken into account. Due to the force of gravity, the weight 10 exerts a certain force on the key 8, but in this state the spring force is greater is and the switch 4 remains in the "off" position.
In Figur 4 ist eine schematische Darstellung des erfindungsgemäßen Schalters 4 gezeigt, wobei das Gewicht 10 über das forminstabile Verbindungsmittel 9 die Taste 8 niederdrückt und so einen Stromkreis schließt. Durch die Neigung der Tür ist die Kraftkomponente des Verbindungsmittels 9 auf die Taste 8 erhöht worden, so dass die Auflagekraft nunmehr größer ist als die Federkraft und der Schalter 4 in die „An" Stellung übergeht.FIG. 4 shows a schematic illustration of the switch 4 according to the invention, the weight 10 depressing the button 8 via the dimensionally unstable connecting means 9 and thus closing a circuit. Due to the inclination of the door, the force component of the connecting means 9 has been increased to the button 8, so that the contact force is now greater than the spring force and the switch 4 changes to the "on" position.
Der Schwenkwinkel ist werkseitig so bestimmt, dass erst bei einem Auslenken von mehr als beispielsweise 10° der in der Tür befindliche Schalter 4 schaltet. Es kann aber auch zweckmäßig sein, bereits bei einem geringeren Schwenkwinkel den Schalter 4 zu schalten.The swivel angle is determined in the factory in such a way that the switch 4 located in the door only switches when it is deflected by more than 10 °, for example. However, it may also be expedient to switch the switch 4 even at a smaller swivel angle.
Vorteilhafterweise wird der Schalter 4 in der Tür 2 angeordnet, so dass keine Abdichtprobleme gegenüber dem Spülbehälter zu erwarten sind.The switch 4 is advantageously arranged in the door 2, so that no sealing problems with respect to the washing container are to be expected.
Bei einer weiteren, nicht gezeigten Ausführungsform der vorliegenden Erfindung ist es vorteilhaft, neben dem Anschalten der Lichtquelle 5 ein akustisches Signal zu erzeugen, das beispielsweise nach einem gewissen Zeitraum, beispielsweise nach 30 Minuten des Offenstehens der schwenkbar gelagerten Tür 2 ertönt, um an die nicht verschlossene Tür 2 zu erinnern. Mit dem erfindungsgemäßen Schalter 4 in einem Haushaltgerät mit einer um eine horizontale verlaufende Achse schwenkbar gelagerten Tür 2 ist es möglich, dass erst bei Erreichen eines bestimmten Schwenkwinkels der nicht geschlossenen Tür 2 eine Lichtquelle 5 im Innenraum 6 des Haushaltgeräts anschaltet wird, die den Innenraum 6 des Haushaltgeräts ausleuchtet. Somit ist es mit dem Haushaltgerät auch möglich, gemäß den persön- liehen Angewohnheiten des Benutzers, die Tür 2 angelehnt zu lassen, ohne dass eine Lichtquelle 5 angeschaltet wird.In a further embodiment of the present invention, not shown, it is advantageous to generate an acoustic signal in addition to switching on the light source 5, which sounds, for example, after a certain period of time, for example after 30 minutes after the pivotally mounted door 2 has been opened, in order to avoid the locked door 2 to remember. With the switch 4 according to the invention in a household appliance with a door 2 pivotably mounted about a horizontal axis, it is possible for a light source 5 in the interior 6 of the household appliance to be switched on only when a certain pivoting angle of the non-closed door 2 has been reached, which switches on the interior 6 of the household appliance. It is therefore also possible with the household appliance, in accordance with the personal habits of the user, to leave the door 2 ajar without a light source 5 being switched on.
Ein mit dem erfindungsgemäßen 4 Schalter ausgestattetes erfindungsgemäßes Haushaltgerät weist somit den Vorteil auf, dass eine Lichtquelle 5 immer dann angeschaltet wird, wenn die Tür 2 soweit aufgeschwenkt ist, dass sie eine potentielle Gefahrenquelle darstellen kann, jedoch bei einem geringen Schwenkwinkel der Tür 2 kein Licht eingeschaltet wird. Auch muss der Benutzer des Haushaltgeräts, der beispielsweise in das Haushaltgerät einzufüllendes Gut tragend die unbeleuchtete Küche betritt, zum Beladen des Haushaltgeräts nicht eigens hierfür das Raumlicht einschalten, sondern hat nach einfachem Abstellen des Guts und Öffnen des Haushaltgeräts ausreichend Licht, um das Haushaltgerät beladen zu können.A household appliance according to the invention equipped with the 4 switch according to the invention thus has the advantage that a light source 5 is always switched on when the door 2 is swung open to such an extent that it can represent a potential source of danger, but no light when the door 2 is pivoted slightly is switched on. Also, the user of the household appliance, who enters the unlit kitchen, for example, carrying goods to be filled into the household appliance, does not have to switch on the room light specifically for loading the household appliance, but instead has sufficient light to simply load the goods and open the household appliance to load the household appliance can.
Mit der Erfindung ist ein Haushaltgerät mit einer um eine horizontal verlaufende Achse schwenkbar gelagerten Tür 2 geschaffen, das auch bei weit geöffneter Tür 2 kein erhöh- tes Gefahrenpotential darstellt, sowie ferner ein Schalter 4 bereitgestellt, der auch Zwischenzustände der Türposition „erkennt". The invention provides a household appliance with a door 2 pivotably mounted about a horizontally extending axis, which does not represent an increased risk potential even when the door 2 is wide open, and a switch 4 which also “detects” intermediate states of the door position.
