Description

Die vorliegende Erfindung betrifft einen Reinigungsautomaten nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zum Öffnen einer Tür eines Reinigungsautomaten gemäß dem Oberbegriff des Anspruchs 12.The present invention relates to a cleaning machine according to the preamble of claim 1 and a method for opening a door of a cleaning machine according to the preamble of claim 12.

Die DE 10 2005 028 449 A1 offenbart einen Geschirrspüler mit einem Spülbehälter, der durch eine schwenkbare Tür verschließbar ist, wobei zum Verschließen eine an der Tür angeordnete Verriegelungseinrichtung in einen am Spülbehälter angeordneten Schließkloben greift. Zum spaltweisen Öffnen der Tür durch eine Gerätesteuerung ist der Schließkloben an einer mittels eines Motors verschließbaren Schließplatte angeordnet, wobei die Schließplatte in eine erste Öffnungsposition mit einer geringen Spaltbreite und in eine zweite Öffnungsposition mit einer großen Spaltbreite fahrbar ist. Durch die Möglichkeit, die Tür automatisch in eine Öffnungsposition zu fahren, bei der diese um einen Spalt von mehreren Zentimetern geöffnet wird, wird die Trocknung nach einem Reinigungsvorgang vorteilhaft unterstützt.The DE 10 2005 028 449 A1 discloses a dishwasher with a rinsing container which can be closed by a pivotable door, wherein, for closing, a locking device arranged on the door engages in a closing clamp arranged on the rinsing container. For a gap-wise opening of the door by a device control of the locking pin is arranged on a closable by a motor closing plate, wherein the closing plate is movable in a first opening position with a small gap width and in a second opening position with a large gap width. By the possibility of automatically driving the door into an opening position, in which it is opened by a gap of several centimeters, drying after a cleaning process is advantageously supported.

Die Tür eines solchen Geschirrspülers ist als sogenannter Aufreißverschluss ausgebildet, das heißt die Tür ist jederzeit von einem Anwender zu öffnen bzw. zu entriegeln, was bei Reinigungsautomaten wie beispielsweise professionellen Spülmaschinen oder auch Desinfektionsautomaten zu Sicherheitsproblemen führen kann. Insbesondere eine Reinigung bei sehr hohen Temperaturen kann dazu führen, dass auch nach einem mehrere Minuten andauernden Trocknungsvorgang, bei dem die Tür des Reinigungsautomaten bereits um einen Spalt geöffnet ist, die in dem Reinigungsautomat befindlichen Gegenstände noch so heiß sind, dass ein versehentliches Öffnen der Tür vermieden werden muss.The door of such a dishwasher is designed as a so-called zipper, that is, the door is always open or unlock by a user, which can lead to security problems in cleaning machines such as professional dishwashers or disinfection machines. In particular, a cleaning at very high temperatures can cause that even after several minutes of continuous drying process, in which the door of the cleaning machine is already open by a crack, the objects in the cleaning machine are still so hot that accidental opening of the door must be avoided.

Aufgabe der vorliegenden Erfindung ist es daher, einen Reinigungsautomaten sowie ein Verfahren zum Öffnen einer Tür eines Reinigungsautomaten zu schaffen, bei dem ein direktes Öffnen der Tür während oder nach einem Reinigungsvorgang verhindert wird.Object of the present invention is therefore to provide a cleaning machine and a method for opening a door of a cleaning machine, in which a direct opening of the door during or after a cleaning process is prevented.

Diese Aufgabe wird durch einen Reinigungsautomaten mit den Merkmalen des Anspruchs 1 beziehungsweise ein Verfahren zum Öffnen einer Tür eines Reinigungsautomaten mit den Merkmalen des Anspruchs 12 gelöst.This object is achieved by a cleaning machine with the features of claim 1 and a method for opening a door of a cleaning machine with the features of claim 12.

Erfindungsgemäß weist der Reinigungsautomat eine Antriebseinheit auf einer Verfahreinheit auf, an der eine Steuerstange derart linear verfahrbar festgelegt ist, dass die Steuerstange zur Ver- oder Entriegelung der Verfahreinheit in eine an einer Tür des Reinigungsautomaten angeordnete Verriegelungseinrichtung ein- oder ausfahrbar ist. Durch diese von der Antriebseinheit angetriebene Steuerstange, welche zur Ver- oder Entriegelung mit der Verfahreinheit wechselwirkt, ist eine von der Türposition unabhängige Ver- und Entriegelung ermöglicht.According to the invention, the cleaning machine has a drive unit on a track on which a control rod is set linearly movable such that the control rod for locking or unlocking the track is in or out of a arranged on a door of the cleaning machine locking device. By this of the Drive unit driven control rod, which interacts with the track for locking or unlocking, is independent of the door position locking and unlocking possible.

Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments and modifications of the invention are the subject of the dependent claims.

Das Federelement 11 ist dabei bevorzugt als Drehfeder ausgebildet.Each of the latching hooks 9 is biased so that it springs away from the respective latching point 12 of the locking bolt 10, as soon as the control rod 8 is pushed back from its position in which it presses the latching hook or 9 in the respective latching point 12 of the locking block 10. In the embodiment with a plurality of latching hooks 9, these are preferably connected by a spring element 11. The spring element 11 is preferably formed as a torsion spring.

Zur Aktivierung der zweiten Antriebseinheit 6 und damit der Bewegung der Steuerstange 8 ist bevorzugt an der Tür 4 ein mit der Steuereinheit 16 verbundenes Bedienfeld 14 vorgesehen, das ein Bedienelement zur Steuerung dieser zweiten Antriebseinheit aufweist. Dieses Bedienelement kann als Taste oder Schalter ausgebildet sein. In einer bevorzugten Ausbildungsform weist das Bedienfeld 14 zusätzlich ein weiteres Bedienelement zur Eingabe eines Entriegelungssignals auf. Ein solches Bedienelement kann beispielsweise eine Zahlentastatur sein, über die der Anwender einen Zahlencode eingeben muss, um nach dem anschließenden Betätigen der Türöffnungstaste Zugang zur Beladung des Reinigungsautomaten zu bekommen.To activate the second drive unit 6 and thus the movement of the control rod 8, a control panel 16 connected to the control unit 16 is preferably provided on the door 4, which has an operating element for controlling this second drive unit. This control can be designed as a button or switch. In a preferred embodiment, the control panel 14 additionally has a further operating element for inputting an unlocking signal. Such an operating element may be, for example, a numeric keypad via which the user must enter a numerical code in order to access the loading of the cleaning machine after the subsequent actuation of the door opening button.

Während des Betriebs erfolgt das Öffnen der Tür 4 des Reinigungsautomaten dergestalt, dass nach einem Programmablauf zunächst durch Ansteuerung der ersten Antriebseinheit 2 die Verfahreinheit 1 in Richtung der Verriegelungseinrichtung 10 geschoben wird und dabei die Tür 4 in eine erste Öffnungsposition geschoben wird, um eine Trocknung der Beladung des Reinigungsbehälters zu unterstützen. Dazu wird die Verfahreinheit 1 etwa 10 cm in Richtung der Tür motorisch verfahren. Um nach dem Trocknungsvorgang die Tür öffnen zu können, muss von einem Anwender zunächst ein Entriegelungssignal über das Bedienfeld 14 eingegeben werden, beispielsweise durch Eingabe eines Zahlencodes über eine Zahlentastatur des Bedienfelds 14. Erst danach bewirkt ein Betätigen einer Türöffnungstaste des Bedienfelds 14 die Aussendung eines Entriegelungssignals an die Steuereinheit 16, welche sodann die zweite Antriebseinheit 6 aktiviert und die Steuerstange 8 in eine Position fährt, bei der der oder die Rasthaken aus den Raststellen 12 des Schließklobens 10 herausfedern. Durch dieses Außereingriffbringen der Verriegelungseinrichtung 10 mit der Verfahreinheit ist die Tür 4 entriegelt, so dass diese vollständig geöffnet werden kann.During operation, the opening of the door 4 of the cleaning machine takes place such that after a program first by moving the first drive unit 2, the track 1 is pushed in the direction of the locking device 10 while the door 4 is pushed into a first opening position to a drying of To support loading of the cleaning tank. For this, the track unit 1 is moved about 10 cm in the direction of the door by motor. In order to be able to open the door after the drying process, a user first has to enter an unlocking signal via the control panel 14, for example by entering a numerical code via a numeric keypad of the control panel 14. Only then does a door opening key of the control panel 14 actuate the emission of an unlocking signal to the control unit 16, which then activates the second drive unit 6 and the control rod 8 moves to a position in which the one or more locking hooks spring out of the locking points 12 of the locking block 10. By this disengagement of the locking device 10 with the track the door 4 is unlocked so that it can be fully opened.
