Description
Die Erfindung betrifft eine Geschirrspülmaschine gemäß den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a dishwasher according to the Features of the preamble of claim 1.
Bei Geschirrspülmaschinen wird die jeweilige Belade- und Ent ladeöffnung üblicherweise durch eine Tür verschlossen, die in ihrem oberen Bereich mit einem Verschluß versehen ist. Dabei greift im geschlossenen Zustand der Spülmaschine ein an dem Verschluß angeordnetes hakenförmiges Teil (Falle) in einen an dem Maschinengehäuse angeordneten Schließkloben ein (vgl. z. B. DE 42 32 834 A1).In dishwashers, the respective loading and unloading loading opening usually closed by a door that in its upper area is provided with a closure. Here intervenes when the dishwasher is closed Clasp arranged hook-shaped part (latch) in one a locking block arranged on the machine housing (see e.g. DE 42 32 834 A1).
Nachteilig ist bei den bekannten Geschirrspülmaschinen vor allem, daß in dem Fall, daß die Spülmaschine nicht sofort nach dem Gebrauch geöffnet wird (z. B. mehrstündige Abwesenheit des Verwenders der Maschine), der nach dem Trocknen in der Maschine verbleibende Wasserdampf sich auf dem Geschirr niederschlägt und zu Flecken auf dem Spülgut führt, weil sich entsprechende tropfenförmige Kalkteile auf diesem ablagern.The known dishwashers are disadvantageous all that in the event that the dishwasher is not immediately after opened for use (e.g. absence of the Machine) after drying in the machine remaining water vapor is deposited on the dishes and leads to stains on the items to be washed because there are corresponding ones Place drop-shaped limestone parts on this.
Aus der US 4,951,693 ist eine Geschirrspülmaschine bekannt, bei der das Geschirr nicht durch einen erwärmten Luftstrom bei ge schlossener Belade- und Entnahmeöffnung getrocknet wird, sondern durch die über eine Öffnung der Tür in die Maschine gelangende Umgebungsluft. Nach dem letzten Spülgang wird daher die Tür mittels eines Elektromagneten entriegelt und zusätzli che an den Türangeln angeordnete federbelastete Öffnungselemen te drücken die Tür etwas nach vorne, so daß sich ein vorgebba rer Öffnungsspalt zum Einströmen der Luft in die Geschirrspül maschine ergibt.A dishwasher is known from US Pat. No. 4,951,693 that the dishes are not caused by a heated air flow closed loading and removal opening is dried, but through the opening of the door into the machine ambient air entering. So after the last rinse unlocked the door by means of an electromagnet and additional spring-loaded opening elements arranged on the door hinges te push the door forward a little so that a predetermined Opening gap for air to flow into the dishwasher machine results.
Der Erfindung liegt die Aufgabe zugrunde, eine Geschirrspülma schine anzugeben, bei der auch bei mehrstündiger Abwesenheit des Verwenders nach dem Abschalten der Spülmaschine keine Flecken auf dem Spülgut auftreten.The invention has for its object a dishwasher Specify the machine, even if you are absent for several hours of the user after switching off the There are no stains on the dishes.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Weitere beson ders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of characterizing part of claim 1 solved. More particular disclose advantageous embodiments of the invention the subclaims.
Die Erfindung berührt im wesentlichen auf dem Gedanken, daß der Schließkloben längsverschiebbar an dem Maschinengehäuse angeordnet ist, so daß dich nach Abschluß des Trockenvor ganges die Tür mittels eines Elektromotors einen spaltbreit öffnen läßt und der Wasserdampf nach außen entweichen kann. Über eine entsprechende mit dem Programmwerk der Spülmaschine gekoppelte Steuervorrichtung kann der Verschiebevorgang nach dem Trockenvorgang eingeleitet und z. B. nach einer vorgegebe nen Zeit durch Zurückziehen des Schließklobens in seine Aus gangsstellung beendet werden.The invention essentially touches on the idea that the locking block can be moved longitudinally on the machine housing is arranged so that you can complete the dry before the door a gap width by means of an electric motor can be opened and the water vapor can escape to the outside. Via a corresponding one with the dishwasher program coupled control device can move to initiated the drying process and z. B. after a given time by pulling the locking block out gear position are ended.
Bei einer vorteilhaften Ausbildung der Erfindung bilden Schließkloben, Elektromotor und Getriebe eine austauschbare Baueinheit. Dadurch ist es möglich, ältere Geschirrspülma schinen auf einfache Weise umzurüsten sowie bei Störungen der einzelnen Baugruppen diese durch den Austausch der gesamten Baueinheit schnell durch eine neue Baueinheit mit bereits aufeinander abgeglichenen Baugruppen zu ersetzen.Form in an advantageous embodiment of the invention Closing block, electric motor and gearbox are interchangeable Unit. This makes it possible to wash older dishes retrofit machines in a simple manner and in the event of malfunctions individual assemblies by replacing the whole Unit quickly through a new unit with already to replace matched assemblies.
Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den folgenden anhand von Figuren erläuterten Ausführungs beispielen. Es zeigen:Further details and advantages of the invention emerge from the following embodiment explained with reference to figures examples. Show it:

Fig. 4 die Draufsicht auf eine aus Schließkloben, Elektromotor und Getriebe bestehende Baueinheit und Fig. 4 is a plan view of a unit consisting of locking block, electric motor and gear and
Fig. 5 eine Draufsicht auf den Schließkloben der in Fig. 4 dar gestellten Baueinheit. Fig. 5 is a plan view of the locking block of the assembly shown in Fig. 4.
In Fig. 1 ist mit 1 eine Geschirrspülmaschine bezeichnet, die aus einem Maschinengehäuse 2 mit einer zum Be- und Entladen des Geschirrs vorderseitigen Öffnung 3 und einer die Öffnung 3 verschließenden Tür 4 besteht. Am oberen Ende der Gehäuse öffnung 3 ist eine Baueinheit 5 mit einem Schließkloben 6 angeordnet.In Fig. 1, 1 denotes a dishwasher, which consists of a machine housing 2 with an opening 3 on the front for loading and unloading the dishes and a door 4 closing the opening 3 . At the upper end of the housing opening 3 , a structural unit 5 with a locking block 6 is arranged.
Wie aus Fig. 2 hervorgeht, greift der Schließkloben 6 bei ge schlossener Tür in eine Falle 7 eines in der Tür 4 angeordne ten Verschlusses 8 ein und hält die Tür 4 zu. Dabei ist mit 9 in Fig. 2 eine Öffnungstaste zum öffnen der Tür 4 bezeichnet.As can be seen from Fig. 2, the locking block 6 engages with a closed door in a trap 7 of a in the door 4 angeordne th closure 8 and holds the door 4 . An opening button for opening the door 4 is designated by 9 in FIG. 2.
Erfindungsgemäß ist der Schließkloben 6 verschiebbar inner halb der Baueinheit 5 angeordnet. Dabei wird bei ausgefahre ner Klobenstellung - wie in Fig. 3 dargestellt - die Tür 4 weiterhin vom Verschluß 8 festgehalten. Die Tür 4 ist aber nicht mehr in die Türdichtung gepreßt, so daß der gegebenen falls in dem Innenraum der Spülmaschine 1 vorhandene Wasser dampf entweichen kann. According to the locking block 6 is slidably arranged half inside the unit 5 . In this case, the door 4 is still held by the closure 8 when the block position is extended, as shown in FIG . However, the door 4 is no longer pressed into the door seal, so that any water that may be present in the interior of the dishwasher 1 can escape.
Die Fig. 4 und 5 zeigen den Aufbau der Baueinheit 5. Im we sentlichen besteht sie aus einem Gehäuse 10 (dessen Frontteil aus Übersichtlichkeitsgründen nicht dargestellt ist), dem in dem Gehäuse 10 verschiebbar gelagerten Schließkloben 6, einem Elektromotor 11, der über zwei elektrische Verbindungen 12, 13 mit dem aus übersichtlichkeitsgründen nicht dargestellten Programmwerk der Spülmaschine 1 verbunden ist und einem Ge triebe 14, welches den Motor 11 mit dem Schließkloben 6 ver bindet. Die aus Motor 11 und Getriebe 14 bestehende Einheit sollte vorzugsweise selbstsperrend ausgelegt sein, um ein Verschieben des Klobens 6 bei Stillstand des Motors 11 auszuschließen. In dem dargestellten Ausführungsbeispiel erfolgt die Selbstsperrung durch Verwendung einer Schnec kenwelle 15, die auf der Motorwelle 16 befestigt ist. FIGS. 4 and 5 show the structure of the unit 5. In essence, it consists of a housing 10 (the front part is not shown for reasons of clarity), the locking block 6 slidably mounted in the housing 10 , an electric motor 11 , which has two electrical connections 12 , 13 with the program of the dishwasher, not shown for reasons of clarity 1 is connected and a Ge gear 14 , which binds the motor 11 with the locking block 6 ver. The unit consisting of motor 11 and transmission 14 should preferably be designed to be self-locking in order to prevent the block 6 from moving when the motor 11 is at a standstill. In the illustrated embodiment, the self-locking takes place by using a Schnec kenwelle 15 , which is attached to the motor shaft 16 .
Das Drehmoment der Motorwelle 16 wird über die Schneckenwelle 15 und über zwei weitere mit 17 und 18 bezeichnete Zahnräder auf ein Ritzel 19 übertragen, das in die Zähne einer mit dem Kloben 6 verbundenen Zahnstange 20 eingreift (Fig. 5). Die Zahnstange 20 ist dabei in einer Ausnehmung 21 des Klobens 6 angeordnet.The torque of the motor shaft 16 is transmitted via the worm shaft 15 and via two further gearwheels designated 17 and 18 to a pinion 19 which engages in the teeth of a rack 20 connected to the block 6 ( FIG. 5). The rack 20 is arranged in a recess 21 of the block 6 .
In Fig. 5 sind in dem Gehäuse 10 der Baueinheit 5 zwei An schlagsflächen 22, 23 vorgesehen, die die Endlagen des Schließklobens 6 vorgeben. Dabei wird die Anschlagsfläche 22 durch die Innenwand des Gehäuses 10 in dem Bereich, in dem die Rückseite des Klobens 6 diese Wand in der einen Endstel lung berührt, gebildet. Die Anschlagsfläche 23 wird durch eine separate innerhalb der Ausnehmung 21 angeordnete Metall platte 24 gebildet, gegen die die der Rückseite 25 des Klo bens 6 zugewandte Wand 26 der Ausnehmung 21 drückt, wenn sich der Schließkloben 6 in seiner vorderen Stellung befin det.In Fig. 5 two striking surfaces 22 , 23 are provided in the housing 10 of the unit 5 , which specify the end positions of the locking block 6 . The stop surface 22 is formed by the inner wall of the housing 10 in the area in which the back of the block 6 touches this wall in one end position. The stop surface 23 is formed by a separate plate 24 arranged within the recess 21 , against which the rear side 25 of the toilet block 6 facing wall 26 of the recess 21 presses when the locking block 6 is in its forward position.
Im folgenden wird auf den Funktionsablauf der erfindungs gemäßen Geschirrspülmaschine eingegangen:In the following, the functional sequence of the invention according to the dishwasher:
Nach dem Beladen der Geschirrspülmaschine 1 über die Öffnung 3 wird die Tür 4 geschlossen (Fig. 2) und über das gewählte Spülprogramm das Programmwerk entsprechend eingestellt. Nach Abschluß des Spül- und Trockenvorganges gibt das Programmwerk zunächst den Verschluß 8 zum öffnen der Tür 4 frei. Sofern die Tür nicht innerhalb einer vorgegebenen Zeitspanne, z. B. 5 Minuten, geöffnet wird, erzeugt das Programmwerk einen Impuls, der ein Anschalten des Elektromotors 11 und damit eine Verschiebung des Schließklobens 6 in Richtung des Verschlusses 8 bewirkt. Diese Verschiebebewegung erfolgt so lange, bis die Wand 26 des Schließklobens gegen die An schlagsfläche 23 der Metallplatte 24 stößt und ein entspre chender, nicht dargestellter Kontaktschalter den Elektromotor 11 abschaltet und die Drehrichtung des Motors umschaltet (Fig. 3).After loading the dishwasher 1 through the opening 3 , the door 4 is closed ( FIG. 2) and the program is set accordingly via the selected washing program. After completion of the rinsing and drying process, the program first releases the lock 8 for opening the door 4 . If the door is not within a predetermined period, e.g. B. 5 minutes, is opened, the program generates a pulse that causes the electric motor 11 to be switched on and thus causes the locking block 6 to be displaced in the direction of the closure 8 . This displacement movement continues until the wall 26 of the locking block abuts against the striking surface 23 of the metal plate 24 and a corresponding contact switch, not shown, switches off the electric motor 11 and switches the direction of rotation of the motor ( FIG. 3).
In dieser Stellung verharrt die Geschirrspülmaschine 1 ebenfalls eine vorgebbare Zeit, die derart gewählt ist, daß der Wasserdampf sicher aus der Maschine 1 entwichen ist. Anschließend erzeugt das Programmwerk wiederum einen Impuls, der den Elektromotor 11 startet, so daß sich der Schließ kloben 6 zurück in seine Ausgangsstellung bewegt. Nachdem die Rückseite 25 des Klobens 6 die Anschlagsfläche 22 erreicht hat, schaltet ein entsprechender Kontaktschalter (nicht dargestellt) den Elektromotor 11 wieder aus und die Dreh richtung des Motors 11 entsprechend um. Die Tür 4 kann nun zur Geschirrentnahme, etwa durch Betätigung der Öffnungstaste 9, wieder geöffnet werden. In this position, the dishwasher 1 also remains for a predetermined time, which is selected such that the water vapor has escaped safely from the machine 1 . Then the program again generates a pulse that starts the electric motor 11 so that the locking block 6 moves back to its starting position. After the back 25 of the block 6 has reached the stop surface 22 , a corresponding contact switch (not shown) switches the electric motor 11 off again and the direction of rotation of the motor 11 accordingly. The door 4 can now be opened again for the removal of dishes, for example by pressing the opening button 9 .
Selbstverständlich ist die Erfindung nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. So hat es sich beispielsweise als besonders vorteilhaft erwiesen, wenn die elektrische Ansteuerung des Schließklobens 6 derart erfolgt, daß die Tür 4 nach Ablauf des Programms leicht geöffnet bleibt. Dieses hat ein leichteres öffnen und Schließen der Tür 4 zur Folge, da die Tür 4 nicht in die Dichtung, mit der die Öffnung 3 (Fig. 1) randseitig abgedichtet wird, gepreßt werden muß. Erst bei Beginn des Waschvorganges bzw. des Pro grammstartes wird der Schließkloben 6 dann in die Endstellung gezogen und damit die Tür 4 ordnungsgemäß verschlossen.Of course, the invention is not limited to the exemplary embodiment described above. For example, it has proven to be particularly advantageous if the electrical actuation of the locking block 6 takes place in such a way that the door 4 remains slightly open after the program has ended. This results in easier opening and closing of the door 4 , since the door 4 does not have to be pressed into the seal with which the opening 3 ( FIG. 1) is sealed at the edge. Only at the beginning of the washing process or the start of the program, the locking block 6 is then pulled into the end position and the door 4 is closed properly.
