Abstract
Description
Die Erfindung betrifft eine Sicherheitseinrichtung für wasserführende Haushaltgeräte, insbe sondere für Wasch- und Geschirrspülmaschinen, mit einer schwimmerbetätigten elektrischen . Schalteinrichtung zum Steuern des Wasserzulaufs im Falle eines Lecks, bei dem aus dem re gulären Wasserführungssystem des Gerätes Wasser in eine Auffangwanne gelangt, in welcher der Schwimmer und die Schalteinrichtung innerhalb eines Gehäuses angeordnet ist.The invention relates to a safety device for water-bearing household appliances, in particular especially for washing machines and dishwashers, with a float-operated electrical. Switching device for controlling the water supply in the event of a leak, in which from the right gular water supply system of the device water in a drip pan, in which the float and the switching device is arranged within a housing.
Eine solche Einrichtung ist aus der DE 41 01 763 A1 bekannt. Dabei ist in einem als Fußplatte bezeichneten Bodenblech eines Haushaltgerätes eine Vertiefung als Auffangwanne eingear beitet. Von dieser Vertiefung wird ein scheibenförmiger Schwimmer aufgenommen, über dem eine Schalteinrichtung plaziert ist. Die Schalteinrichtung ist durch Montageböcke mit dem Bo denblech verbunden. Über der Schalteinrichtung und dem Schwimmer ist ein glockenförmiges Gehäuse angeordnet und in nicht näher beschriebener Art am Bodenblech befestigt. Durch die Verwendung einer nach unten geöffneten Glocke und einer separaten Schalteinrichtung müs sen zur Montage der Sicherheitseinrichtung mehrere Einzelteile auf das Bodenblech gelegt bzw. auf diesem befestigt werden. Dies führt zu einer aufwendigen Fertigung. Außerdem kann die Einrichtung erst im montierten Zustand getestet werden, Defekte würden deshalb eine De montage erfordern.Such a device is known from DE 41 01 763 A1. One is as a base plate designated base plate of a household appliance a recess as a sump beitet. A disc-shaped float is received from this recess, above which a switching device is placed. The switching device is connected to the Bo connected the sheet metal. Above the switch and the float is a bell-shaped one Housing arranged and attached to the floor panel in a manner not described in detail. Through the Use of a bell open at the bottom and a separate switching device put several individual parts on the floor panel to assemble the safety device or attached to it. This leads to complex production. Besides, can the device can only be tested in the assembled state, defects would therefore be a De require assembly.
Bajonettverschlüsse als leicht lösbare Verbindungselemente sind allgemein bekannt (s. O. Richter, R. v. Voss: Bauelemente der Feinmechanik; 5. Auflage; Berlin; Verlag Technik, 1952; S. 177-182).Bayonet locks as easily detachable connecting elements are generally known (see above Richter, R. v. Voss: components of precision engineering; 5th edition; Berlin; Verlag Technik, 1952; Pp. 177-182).
Der Erfindung stellt sich somit das Problem, eine hinsichtlich ihrer Montage optimierte Sicher heitseinrichtung der eingangs genannten Art zu offenbaren.The invention thus poses the problem of ensuring that its installation is optimized to disclose unit of the type mentioned.
Erfindungsgemäß wird dieses Problem durch eine Sicherheitseinrichtung für wasserführende Haushaltgeräte mit den im Patentanspruch angegebenen Merkmalen gelöst.According to the invention, this problem is solved by a safety device for water-carrying Household appliances with the features specified in the claim solved.
Der mit der Erfindung erreichbare Vorteil besteht darin, das die gesamte Sicherheitseinrichtung als Baugruppe vorgefertigt und geprüft werden kann und anschließend ohne zusätzliche Befe stigungsmittel mit dem Bodenblech bzw. einer darin angeordneten Auffangwanne verbunden werden kann.The advantage achievable with the invention is that the entire safety device can be prefabricated and tested as an assembly and then without additional attachments Stigungsmittel connected to the bottom plate or a sump arranged therein can be.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen rein schematisch dargestellt und wird nachfolgend näher beschrieben. Es zeigtAn embodiment of the invention is shown purely schematically in the drawings and is described in more detail below. It shows
Fig. 1 die erfindungsgemäß aufgebaute Sicherheitseinrichtung im Querschnitt Fig. 1 shows the safety device constructed according to the invention in cross section
Fig. 2 die Auffangwanne von unten mit montierter Sicherheitseinrichtung Fig. 2 shows the sump from below with the safety device installed
Die in Fig. 1 dargestellte Sicherheitseinrichtung besitzt ein in axialer Richtung geteiltes, als Kuntsstoffspritzteil gefertigtes Gehäuse (1). Durch die Teilung entstehen zwei Hälften, die durch ein Filmscharnier (2) verbunden sind. Diese werden um einen scheibenförmigen Schwimmkör per (3) und einen Mikroschalter (4) herum geschlossen und mit einer Rastvorrichtung (5) ver riegelt. Der Schwimmkörper (3) besitzt an seiner Oberseite einen Betätigungsfinger (3a). Direkt über dem Betätigungsfinger (3a) befindet sich der Schaltstößel (4a) des Mikroschalters (4), der über Anschlußfahnen (4b) in nicht dargestellter Weise mit der Programmsteuerung des Haus haltgeräts verbunden ist.The safety device shown in FIG. 1 has a housing ( 1 ) which is divided in the axial direction and manufactured as a plastic injection-molded part. The division creates two halves, which are connected by a film hinge ( 2 ). These are closed by a disc-shaped float ( 3 ) and a microswitch ( 4 ) and locked with a locking device ( 5 ). The float ( 3 ) has an actuating finger ( 3 a) on its top. Directly above the actuating finger ( 3 a) is the switching plunger ( 4 a) of the microswitch ( 4 ), which is connected via terminal lugs ( 4 b) in a manner not shown to the program control of the household device.
An der Unterseite des Gehäuses (1) (in Fig. 2 gestrichelt dargestellt) ist ein Riegel angeformt, der aus einem Ansatzstück (6) und zwei gegenüberliegenden Flügeln (7) in Form von Kreis segmenten besteht. Die nach oben gerichteten Flächen der Flügel (7) besitzen Anlaufschrä gen (8). Um den Riegel herum ist an die Gehäuseunterseite (1a) eine Santoprenedichtung (9) angespritzt.On the underside of the housing ( 1 ) (shown in dashed lines in Fig. 2), a bolt is formed, which consists of an extension ( 6 ) and two opposite wings ( 7 ) in the form of circular segments. The upward-facing surfaces of the wings ( 7 ) have chamfers ( 8 ). A santoprene seal ( 9 ) is molded around the latch on the underside of the housing ( 1 a).
In dem nicht vollständig dargestellten Bodenblech des Haushaltgeräts ist als Auffangwan ne (10) eine Vertiefung geprägt. In das Zentrum der Auffangwanne ist ein Blechausschnitt (11) gestanzt, der als Riegelfalle mit dem Riegel einen Bajonettverschluß bildet. Zur Befestigung des Gehäuses (1) werden dessen Flügel (7) durch den Blechausschnitt (11) gesteckt und durch Drehung gegen den Uhrzeigersinn mit der Wanne (10) verriegelt. Dabei bildet die Santoprene dichtung (9) eine geschlossenen Kontur um den Blechausschnitt (11). Die Anlaufschrägen (8) bewirken ein Anpressen der Dichtung (9) an die Wanne (10), so daß ein Austreten von Wasser aus dem Blechausschnitt (11) verhindert wird. Eine an die Unterseite (1a) angeformte Na se (12) begrenzt den Drehweg des Gehäuses (1).In the bottom plate of the household appliance, which is not shown in full, a recess is shaped as a catch pan ( 10 ). A sheet metal cutout ( 11 ) is punched into the center of the collecting trough, which forms a bayonet lock with the bolt as a latch catch. To fasten the housing ( 1 ), its wings ( 7 ) are inserted through the sheet metal cutout ( 11 ) and locked to the tub ( 10 ) by turning counterclockwise. The Santoprene seal ( 9 ) forms a closed contour around the sheet cutout ( 11 ). The run-on bevels ( 8 ) cause the seal ( 9 ) to be pressed against the trough ( 10 ), so that water cannot escape from the sheet metal cutout ( 11 ). A molded on the underside ( 1 a) Na se ( 12 ) limits the rotation of the housing ( 1 ).
