Description

Die Erfindung betrifft eine frontbeschickbare Wäschebehandlungsmaschine wie Waschmaschine, Waschtrockner oder Wäschetrockner mit einer an der Frontwand angeordneten Beladungsöffnung, die mittels einer schwenkbaren Tür verschließbar ist, mit einer Verriegelungsvorrichtung zum Halten der Tür in ihrer Verschlussstellung und mit einer Betätigungseinrichtung zum Aktivieren oder Deaktivieren der Verriegelungsvorrichtung.The invention relates to a front-loading laundry treatment machine such as washing machine, washer-dryer or dryer with a arranged on the front wall loading opening, which is closed by a hinged door, with a locking device for holding the door in its closed position and with an actuating device for activating or deactivating the locking device.

Eine derartige frontbeschickbare Wäschebehandlungsmaschine ist aus der DE 199 32 141 A1 bekannt. Bei dieser bekannten Wäschebehandlungsmaschine ist eine Türöffnungstaste in der Frontwand in unmittelbarer Nähe zur schwenkbaren Tür im Bereich der Verriegelungseinrichtung angeordnet. Der Benutzer muss zum Öffnen der Tür auf die Türöffnungstaste drücken und kann nahezu gleichzeitig die aufspringende Tür am Rand fassen, um die Tür anschließend durch eine Schwenkbewegung zu öffnen. Diese Art der Türöffnung mutet recht komfortabel an, sie erfordert aber vom Bediener zwei Bewegungen in unterschiedliche Richtungen. Im ersten Schritt muss die Taste in Richtung Frontwand hineingedrückt, was einer entgegengesetzten Bewegung zum Öffnen der Tür entspricht, und danach muss die Tür am Rahmen gezogen werden, damit die öffnende Schwenkbewegung zustande kommt. Dies ist eine von der Frontwand wegweisende Bewegung.Such a front loadable laundry treatment machine is from the DE 199 32 141 A1 known. In this known laundry treatment machine, a door opening button is arranged in the front wall in the immediate vicinity of the pivotable door in the region of the locking device. The user must press the door opening button to open the door and can almost simultaneously grasp the opening door at the edge to subsequently open the door by a pivoting movement. This type of door opening seems quite comfortable, but it requires the operator two movements in different directions. In the first step, the button must be pressed towards the front wall, which corresponds to an opposite movement to open the door, and then the door must be pulled on the frame for the opening pivoting movement to occur. This is a movement pointing away from the front wall.

Aus der WO 02/14593 A2 ist eine frontbeschickbare Wäschebehandlungsmaschine bekannt, die einen großflächigen Türöffnungshebel direkt an der Tür besitzt. Dieser Türöffnungshebel ist mit einer Vielzahl von Bedienelementen ausgestattet, um beispielsweise Programmparameter einzustellen. Zu Anzeige von Statusinformationen sind auf dem umlaufenden Rahmen der Tür und auf dem Türöffnungshebel Leuchtmittel angeordnet, die eine Beobachtung und Zustanderkennung aus einer Entfernung ermöglichen. Die Vielzahl von Bedien- und Anzeigeelementen auf dem Türöffnungshebel birgt die Gefahr, dass beim Betätigen eine ungewollte Fehlbedienung möglich ist, wenn beispielsweise versehentlich ein Bedienelement für die Auswahl eines Programmparameters betätigt wird.From the WO 02/14593 A2 is known a front loadable laundry treating machine having a large-scale door opening lever directly to the door. This door opening lever is equipped with a variety of controls, for example, to set program parameters. In order to display status information, illuminants are arranged on the surrounding frame of the door and on the door opening lever, which allow observation and status recognition from a distance. The large number of operating and display elements on the door opening lever involves the risk that an undesired operation error is possible when operating, for example, if an operating element for the selection of a program parameter is inadvertently actuated.

Der Erfindung liegt somit die Aufgabe zugrunde, den Bedienkomfort einer frontbeschickbaren Wäschebehandlungsmaschine, wie Waschmaschine, Waschtrockner oder Wäschetrockner, zu verbessern.The invention is therefore an object of the invention to improve the ease of use of a front loadable laundry treatment machine, such as washing machine, washer-dryer or tumble dryer.

Erfindungsgemäß wird dieses Problem durch eine frontbeschickbare Wäschebehandlungsmaschine mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden abhängigen Ansprüchen.According to the invention, this problem is solved by a front-loading laundry treatment machine having the features of patent claim 1. Advantageous embodiments and modifications of the invention will become apparent from the following dependent claims.

Der mit der Erfindung erreichbare Vorteil besteht darin, dass eine einfache und komfortable Handhabung für die Türöffnung bereitgestellt wird. Dies wird dadurch erreicht, dass die Betätigungseinrichtung zumindest einen Sensor umfasst, mit dem eine Berührung oder ein berührungsloser Eingriff in seinen Wirkbereich feststellbar ist, wobei der zumindest eine Sensor an der Tür selbst oder an der Frontwand im Bereich der Aufnahme der Tür angeordnet ist. Beim Zugreifen auf den Rahmen der Tür gerät die Hand des Benutzers in den Wirkbereich des Sensors, wodurch die Steuereinrichtung ein Signal erhält, welches das Deaktivieren der Verriegelungseinrichtung veranlasst. Der Benutzer braucht keine Kraft aufwenden, um die Tür aus der Raststellung herauszuziehen oder eine Handhabe zu betätigen, um die Verriegelungseinrichtung zu deaktivieren oder die Tür zu entriegeln.The advantage achievable with the invention is that a simple and comfortable handling for the door opening is provided. This is achieved in that the actuating device comprises at least one sensor with which a touch or a non-contact engagement is detectable in its effective range, wherein the at least one sensor on the door itself or on the front wall in the region of the receiving door is arranged. When accessing the frame of the door, the user's hand comes within the effective range of the sensor, whereby the control device receives a signal, which causes the deactivation of the locking device. The user does not need to apply force to pull the door out of the detent position or to manipulate a handle to deactivate the latch or unlock the door.

In einer zweckmäßigen Ausführungsform ist der Wirkbereich des zumindest einen Sensors in einem Umfangsabschnitt der Tür bzw. Randes der Beschickungsöffnung angeordnet, der sich bei betriebsgemäßer Lage des Haushaltgerätes in einer schräg oberen oder oberen Position der Tür bzw. des Öffnungsrandes befindet. In dieser Position ist der Rand der Tür besonders bequem zu erreichen. Durch das Anlegen der Hand an den Rand der Tür oder beim berührungslosen Eingriff hinter den Rand der Tür wird diese selbständig entriegelt und fällt in die betätigende Hand. Danach kann sie aufgeschwenkt werden, ohne dass ein Umgreifen oder eine Beachtung von Bedienhandhaben nötig ist.In an expedient embodiment, the effective range of the at least one sensor is arranged in a circumferential section of the door or edge of the charging opening, which is in an obliquely upper or upper position of the door or of the opening edge when the domestic appliance is in a suitable position. In this position, the edge of the door is particularly easy to reach. By applying the hand to the edge of the door or the contactless engagement behind the edge of the door this is unlocked automatically and falls into the operating hand. Then it can be swung open, without the need for embracing or observing operating manipulations.

In einer zweckmäßigen Ausführungsform wird als Sensor ein kapazitiver Sensor verwendet, der eine Berührung beispielsweise durch den Bediener, erkennt und ein Signal zum Deaktivieren der Verriegelungseinrichtung veranlasst. Mit diesem Sensor wird ein klar abgegrenzter Wirkbereich bereitgestellt.In an expedient embodiment, a capacitive sensor is used as the sensor, which detects a touch, for example by the operator, and causes a signal to deactivate the locking device. This sensor provides a clearly defined effective range.

In dieser Ausführung ist es zweckmäßig, dass der kapazitive Sensor an bzw. in der Tür im Bereich des Türrandes angeordnet ist. Beim Betätigen greift der Benutzer den Rand der Tür, wodurch beim Zugriff der Sensor berührt wird.In this embodiment, it is expedient that the capacitive sensor is arranged on or in the door in the region of the door edge. Upon actuation, the user grips the edge of the door, thereby touching the sensor upon access.

In einer anderen, vorteilhaften Ausführungsform wird als Sensor ein optischer Sensor verwendet. Beim Eintritt der Hand in den Wirkbereich des Sensors, der sich zwischen dem Rand der Tür und der Frontwand befindet, wird eine Veränderung des auf den Sensor eintretenden Lichts erkannt, wodurch ein Signal zum Deaktivieren der Verriegelungseinrichtung veranlasst wird. Mit diesem Sensor wird eine schnelle Reaktion und ein spontanes Aufspringen der Tür erreicht.In another advantageous embodiment, an optical sensor is used as the sensor. Upon entry of the hand into the effective range of the sensor located between the edge of the door and the front wall, a change in the light entering the sensor is detected, thereby causing a signal to deactivate the locking device. With this sensor a quick reaction and a spontaneous opening of the door is achieved.

In einer vorteilhaften Ausführungsform ist am Rand der Tür auf der zur Frontwand gerichteten Seite zumindest ein Leuchtmittel angeordnet, das im wesentlichen den Wirkbereich des Sensors mit Licht beaufschlagt. Hiermit wird dem Benutzer sehr genau und deutlich angezeigt, wo er an die Tür greifen muss, um sie zu öffnen. Hierbei ist es zweckmäßig, dass das Leuchtmittel von der Steuerungseinrichtung aktivierbar ist. Auf diese Weise ist das Leuchtmittel abhängig vom Programmablauf ansteuerbar, wobei das Leuchtmittel ausgeschaltet ist, wenn die Tür nicht geöffnet werden kann. Das Leuchtmittel wird erst einsgeschaltet, wenn beispielsweise ein Programmablauf beendet ist und der Benutzer aufgefordert wird, die zu behandelnde Wäsche aus der Wäschebehandlungsmaschine zu entnehmen.In an advantageous embodiment, at least one light source is arranged on the edge of the door on the side directed toward the front wall, which illuminates substantially the effective range of the sensor. It clearly shows the user where to reach the door to open it. It is expedient here for the luminous means to be activatable by the control device. In this way, the bulb is dependent can be controlled by the program sequence, wherein the lighting means is turned off when the door can not be opened. The lighting means is only switched on when, for example, a program sequence has ended and the user is asked to remove the laundry to be treated from the laundry treatment machine.

In einer anderen Ausführungsform ist das zumindest eine Leuchtmittel in einem Umfangsabschnitt des Randes der Beladungsöffnung angeordnet, welches im wesentlichen den Wirkbereich des Sensors mit Licht beaufschlagt. Die Wirkungsweise ist die gleiche, wie oben beschrieben, jedoch wird das Licht über Reflektion am inneren Rand der Tür zum Sensor geleitet. Die mit der Steuereinrichtung in Verbindung stehenden Komponenten, wie Sensor und Beleuchtungseinrichtung, sind an bzw. in der Frontwand angeordnet. Die Tür ist frei von diesen Komponenten, so dass keine Signalverbindungen von der im Gerät angeordneten Steuerungseinrichtung zur beweglichen Tür geführt werden müssen.In another embodiment, the at least one lighting means is arranged in a peripheral portion of the edge of the loading opening, which acts on the effective range of the sensor with light substantially. The operation is the same as described above, but the light is directed via reflection at the inner edge of the door to the sensor. The components in communication with the control device, such as sensor and illumination device, are arranged on or in the front wall. The door is free of these components, so that no signal connections from the control device arranged in the device to the movable door must be performed.

In einer zweckmäßigen Ausführungsform ist der optische Sensor auf der Frontwand im Bereich der Aufnahme der Tür in einem Teilumfang um die Beladungsöffnung angeordnet. Hierbei kann das Leuchtmittel für die Aktivierung des optischen Sensors verwendet werden, da beim Eingriff in den Spalt zwischen dem Rand der Tür, welcher das Leuchtmittel enthält, und der Frontwand eine Unterbrechung des Lichtstrahls bzw. eine Verminderung der auf den optischen Sensor wirkenden Lichtintensität verursacht wird.In an expedient embodiment, the optical sensor is arranged on the front wall in the region of the receptacle of the door in a partial circumference about the loading opening. In this case, the illuminant can be used for the activation of the optical sensor, since, when engaging in the gap between the edge of the door, which contains the illuminant, and the front wall, an interruption of the light beam or a reduction of the light intensity acting on the optical sensor is caused ,

an embodiment in a detailed view.

Die in Fig. 1 dargestellte frontbeschickbare Wäschebehandlungsmaschine 1 umfasst in der Frontwand 2 eine Beladungsöffnung, 3, die mittels einer Tür 4, in der dargestellten Ausführung eine Bullaugentür, verschließbar ist. Die Tür 4 ist mittels eines Scharniers 14 an der Frontwand 2 befestigt. Am Rand der Tür 4 ist ein Schließelement 15 angeordnet, welches im geschlossenen Zustand durch die Verriegelungsvorrichtung 6 an der Frontwand 2 gehalten wird. Im geschlossenen Zustand liegt die Tür 4 im etwas zurückversetzten Aufnahmebereich 13 an der Frontwand 2 an, wobei ein zugänglicher Spalt 18 zwischen der Frontwand 2 und dem Rand 10 oder Rahmen der Tür 4 bereitgestellt wird. Im oberen Bereich der Aufnahme 13 ist als Betätigungseinrichtung 7 für die Verriegelungsvorrichtung 6 ein Sensor 8 angeordnet, der bei einem Eingriff in den Wirkbereich 9 die Entriegelung der Tür 4 durch Deaktivieren der Verriegelungsvorrichtung 6 veranlasst.The front-loadable laundry treatment machine 1 shown in FIG. 1 comprises in the front wall 2 a loading opening 3, which can be closed by means of a door 4, in the illustrated embodiment a porthole door. The door 4 is fastened to the front wall 2 by means of a hinge 14. At the edge of the door 4, a closing element 15 is arranged, which is held in the closed state by the locking device 6 on the front wall 2. When closed, the door 4 rests against the front wall 2 in the slightly recessed receiving area 13, an accessible gap 18 being provided between the front wall 2 and the edge 10 or frame of the door 4. In the upper part of the receptacle 13, a sensor 8 is arranged as the actuating means 7 for the locking device 6, the at an intervention in the effective range 9 causes the unlocking of the door 4 by deactivating the locking device 6.

Der Sensor 8 wird durch die Steuerungseinrichtung 5 aktiviert, sobald die Tür 4 freigegeben und geöffnet werden darf. Dies geschieht in der Regel in Abhängigkeit vom Ablauf des eingestellten Behandlungsprogramms, beispielsweise eines Waschprogramms, welcher ebenfalls von der Steuerungseinrichtung 5 gesteuert und kontrolliert wird. Am Rand der Tür 4 auf der zur Frontwand 2 gerichteten Seite ist zumindest ein Leuchtmittel 16 angebracht, welches ebenfalls von der Steuerungseinrichtung 5 steuerbar, bzw. schaltbar ist. Es ist auch möglich, den Sensor 8 und/oder das Leuchtmittel 16 von der Verriegelungsvorrichtung 6 zu aktivieren, so dass die Steuerungseinrichtung 5 nur die Verriegelungseinrichtung 6 abhängig vom Ablauf eines Behandlungsprogramms steuern bzw. schalten muss.The sensor 8 is activated by the control device 5 as soon as the door 4 is allowed to be released and opened. This usually takes place as a function of the sequence of the set treatment program, for example a wash program, which is likewise controlled and controlled by the control device 5. At the edge of the door 4 on the side facing the front wall 2, at least one lighting means 16 is mounted, which is also controllable by the control device 5, or switchable. It is also possible to activate the sensor 8 and / or the lighting means 16 from the locking device 6, so that the control device 5 only has to control or switch the locking device 6 depending on the sequence of a treatment program.

Gemäß Fig. 1 kann in einer vorteilhaften Ausführung der Sensor 8 als Kombinationsbauteil mit einer zusätzlichen oder integrierten Beleuchtungseinrichtung, beispielsweise LED, ausgeführt werden. Dann kann die in der Tür 4 gezeigte Beleuchtungseinrichtung 16 entfallen, so dass alle mit der Steuerungseinrichtung 5 oder mit der Verriegelungseinrichtung 6 in Verbindung stehenden Komponenten in der Wäschebehandlungsmaschine 1 angeordnet sind.According to FIG. 1, in an advantageous embodiment, the sensor 8 can be designed as a combination component with an additional or integrated illumination device, for example LED. Then, the illumination device 16 shown in the door 4 can be omitted, so that all the components in communication with the control device 5 or with the locking device 6 are arranged in the laundry treatment machine 1.

In Fig. 2 ist die frontbeschickbare Wäschebehandlungsmaschine 1 mit geschlossener Tür 4 dargestellt. Der Rand 10 der Tür 4 liegt im Aufnahmebereich 13 an der Frontwand 2 an, wobei ein Spalt 18 zwischen Frontwand 2 und der Innenseite des Türrandes 10 vorgesehen ist. Der Wirkbereich 9 des Sensors 8 (Fig. 1) ist auf einen Teilumfang 12 der Tür 4 bzw. des Öffnungsrandes 11 begrenzt. Ferner ist der Wirkbereich 9 im wesentlichen nur innerhalb des Spaltes 13 aktiv, wodurch verhindert wird, dass Handhabungen an die Außenseite der Tür 4 oder die Annäherung des Benutzers an die Wäschebehandlungsmaschine 1 zu einer ungewollten Betätigung der Verriegelungsvorrichtung 6 bzw. zum Öffnen der Tür 4 führt.In Fig. 2 the frontbeschickbare laundry treatment machine 1 is shown with the door 4 closed. The edge 10 of the door 4 is located in the receiving area 13 on the front wall 2, wherein a gap 18 between the front wall 2 and the inside of the door edge 10 is provided. The effective region 9 of the sensor 8 (FIG. 1) is limited to a partial circumference 12 of the door 4 or the opening edge 11. Furthermore, the effective area 9 is essentially active only within the gap 13, which prevents handling on the outside of the door 4 or the approach of the user to the laundry treatment machine 1 to an unwanted actuation of the locking device 6 and to open the door 4 ,

In Fig. 3 ist die Wäschebehandlungsmaschine 1 in der Schnittdarstellung skizziert. Die Beladungsöffnung 3 für die Trommel 17 ist an der Frontwand 2 durch die Tür 4 verschlossen. Der Rand 10 der Tür 4 liegt im Aufnahmebereich 13 an der Frontwand 2, wobei ein Spalt 18 zwischen der Frontwand 2 und der Innenseite des Türrandes 10 verbleibt. Der Sensor 9 ist im Aufnahmebereich 13 angeordnet, wodurch der Wirkbereich 9 des Sensors 8 auf den Spalt 18 begrenzt wird. An der Innenseite des Türrandes 10 ist im Wirkbereich 9 des Sensors 8 zumindest ein Leuchtmittel 16 angeordnet, welches den sichtbaren Spalt 18 bzw. den Aufnahmebereich 13 der Tür 4 im Umfang zumindest teilweise ausleuchtet.In Fig. 3, the laundry treatment machine 1 is sketched in the sectional view. The loading opening 3 for the drum 17 is closed on the front wall 2 through the door 4. The edge 10 of the door 4 is located in the receiving area 13 on the front wall 2, wherein a gap 18 between the front wall 2 and the inside of the door edge 10 remains. The sensor 9 is arranged in the receiving region 13, whereby the effective region 9 of the sensor 8 is limited to the gap 18. At least one illuminant 16, which illuminates the visible gap 18 or the receiving area 13 of the door 4 in the circumference at least partially, is arranged on the inside of the door edge 10 in the effective region 9 of the sensor 8.

Gemäß Fig. 4 ist die Wäschebehandlungsmaschine 1 mit einem kapazitiven Sensor 8a ausgestattet. Hierbei ist der Sensor 8a im Rand 10 der Tür 4 angeordnet, so dass ein im Umfang der Tür 4 begrenzter Wirkbereich 9 bereitgestellt wird. Das bzw. die Leuchtmittel 16 sind ebenfalls im Randbereich 10 der Tür 4 angeordnet, wodurch bei der Aktivierung des Sensors 8a eine indirekte Beleuchtung des Wirkbereichs 9 an der Frontwand 2 bzw. an dem Aufnahmebereich 13 erfolgt.According to FIG. 4, the laundry treatment machine 1 is equipped with a capacitive sensor 8a. Here, the sensor 8a is arranged in the edge 10 of the door 4, so that an area of the door 4 limited effective range 9 is provided. The one or more bulbs 16 are also arranged in the edge region 10 of the door 4, whereby upon activation of the sensor 8a, an indirect illumination of the effective region 9 on the front wall 2 or on the receiving area 13 takes place.

Gemäß Fig. 4 kann alternativ ein optischer Sensor 8a verwendet werden, so dass keine Komponenten an bzw. in der Frontwand 2 im Aufnahmebereich 13 der Tür 4 angeordnet werden müssen. In dieser Ausführung strahlt das Licht des Leuchtmittels 16 bei geschlossener Tür 4 gegen die Frontwand 2 bzw. gegen den Aufnahmebereich 13 und leuchtet diesen zumindest teilweise aus. Das reflektierte Licht gelangt teilweise zum Sensor 8a, welches beim Zugriff zumindest teilweise unterbrochen wird, wodurch der Sensor 8a eine veränderte Lichtintensität detektiert und die Öffnung bzw. Deaktivierung der Verriegelungsvorrichtung 6 veranlasst.According to FIG. 4, alternatively, an optical sensor 8a can be used, so that no components have to be arranged on or in the front wall 2 in the receiving region 13 of the door 4. In this embodiment, the light of the illuminant 16 radiates with the door 4 closed against the front wall 2 or against the receiving area 13 and illuminates it at least partially. The reflected light passes partially to the sensor 8a, which is at least partially interrupted upon access, whereby the sensor 8a detects a change in light intensity and causes the opening or deactivation of the locking device 6.
