"Sicherheitsvorrichtung für eine Wasch- und Zentrifugler-, Geschirrspülmaschine o. dgl.""Safety device for a washing and centrifuging, Dishwasher or the like "
Die Erfindung betrifft eine Sicherheitsvorrichtung für eine Wasch- und Zentrifugiert-, Geschirrspülmaschine o. dgl., die mit einem mit hoher und niedriger Geschwindigkeit rotierenden Einzelteil und mit einer Tür oder einem Deckel versehen ist, die (der) zu diesem Einzelteil führt, welche Vorrichtung einen Elektromagnet enthalt, der einen Riegel für die Tür oder den Deckel betätigt.The invention relates to a safety device for a washing machine and centrifugation machine, dishwasher or the like a single part rotating at high and low speed and is provided with a door or a lid that leads to this component, which device contains an electromagnet, who operates a latch for the door or the lid.
Zahlreiche Sicherheitssysteme sind für diesen Zweck bekannt. Sie lassen sich in zwei Gruppen einteilen, d.h. mechanische Systeme und elektrische Systeme. Lie ersteren verwenden ein Verzögerungssystem, wodurch es dem Gebraucher unmöglich ist, die Tür oder den Deckel wahrend einer vorher eingestellten Zeitspanne nach dem Unterbrechen der Stromzufuhr an den Motor der Maschine zu Öffnen. Diese Systeme haben den Nachteil, dass ein kompliziertes Gestänge erforderlich ist.Bsi den elektrischen Systemen, denen das vorliegende züge-BAD ORiGJNAL 109825/1510Numerous security systems are known for this purpose. They can be divided into two groups, i.e. mechanical systems and electrical systems. The former use a delay system, which makes it impossible for the user to open the door or the door Open the lid for a pre-set period of time after the power supply to the machine's motor has been disconnected. These Systems have the disadvantage that a complicated linkage is required, as is the case with the electrical systems that the train BAD ORiGJNAL 109825/1510
hört, wird ein Elektromagnet verwendet, dessen Kern zum Verriegeln der Tür verwendet wird, wenn der Magnet erregt ist, so dass die Sicherheit nicht vollkommen ist, da sie von der guten Wirkung des Elektromagneten abhängt.hears, an electromagnet is used, the core of which is used to lock the door is used when the magnet is energized, so the security is not perfect as it depends on the good effect of the Electromagnet depends.
Die vorliegende Erfindung behebt diese Nachteile und ist dadurch gekennzeichnet, dass auf beiden Seiten des Elektromagneten, flucht zu seiner Polachse, zwei Dauermagneten angeordnet sind, deren gleichnamige Pole einander zugewandt sind und dass der Erregerkreis des Elektromagneten zwei Dioden und einen Schalter enthalt, welcher Schalter eine der beiden Dioden ein- und die andere abschaltet oder umgekehrt, so dass der Elektromagnet bei Erregung von einem oder dem anderen Dauermagnet angezogen und der Deckel oder die Tür verriegelt oder entriegelt wird.The present invention overcomes these disadvantages and is characterized in that on both sides of the electromagnet, aligned to its polar axis, two permanent magnets are arranged, whose poles of the same name are facing each other and that the excitation circuit of the electromagnet contains two diodes and a switch, which switch turns one of the two diodes on and the other off or vice versa, so that the electromagnet when energized by one or the other Another permanent magnet is attracted and the lid or door is locked or unlocked.
In einer bevorzugten Ausführungsform der Sicherheitevorrichtung nach der Erfindung wird der Schalter durch eine Programmiervorrichtung der Maschine betätigt.In a preferred embodiment of the safety device according to the invention, the switch is operated by a programming device of the machine.
Die Erfindung wird nachstehend an Hand beiliegender Zeichnung näher erläutert, in derThe invention is explained in more detail below with reference to the accompanying drawing, in which
Fig. 1 ein Schaltbild einer Sicherheitsvorrichtung nach der Erfindung,Fig. 1 is a circuit diagram of a safety device according to the invention,
Fig. 2 eine Ausführungsform einer Sicherheitevorrichtung nach der Erfindung ohn· die elektrischen Verbindungen zeigt.2 shows an embodiment of a security device according to the invention without the electrical connections.
In Fig. 1 wird der Elektromagnet durch den Kern 1 und die Spule 2 dargestellt. An jedem Ende des Kernes 1, in einem geringen Abstand von diesem, wenn der Elektromagnet nicht erregt ist, sind zwei Dauermagneten 3 bzw. 4 angeordnet. Die Spule 2 kann mit den Klemmen 5 und 6 einer Wechselepannungaquelle verbunden werden Ober eine von zwei Dioden 7 und 8 und Ober «inen Schelter 9 «itIn FIG. 1, the electromagnet is represented by the core 1 and the coil 2. At each end of the core 1, at a short distance therefrom when the electromagnet is not energized, two permanent magnets 3 and 4 are arranged. The coil 2 can with terminals 5 and 6 of an alternating voltage source are connected About one of two diodes 7 and 8 and upper shelf 9 zwei Stellungen 10-11 und 10-12. Der Schalter 9 dient iua Durohlae»two positions 10-11 and 10-12. The switch 9 serves iua Durohlae »

een des Stroms in abwechselnden Richtungen zur Spule 2, so dass der Kern 1 abwechselnd von dem Magneten 3 und dem Magneten 4 angezogen wird.een of the current in alternating directions to the coil 2, so that the core 1 is alternately attracted by the magnet 3 and the magnet 4.
Wenn die Sicherheitsvorrichtung nach der Erfindung in einer Wasch- und Zentrifugiermaschine verwendet wird, kann der Schalter 9 durch eine Programmiervorrichtung (nicht dargestellt) derart betätigt werden, dass der Schalter 9 die Stellung 10-11 einnimmt, wenn die Maschine zentrifugiert. Die Polarisierung des Kernes 1 ist dann derart, dass der Kern von dem Magneten 3 angezogen und ein Organ 13 (Fig. 2) zwischen den Haken 14 und die für 15 geschoben wird, wodurch die Tür in der geschlossenen Lage verriegelt wird.When the safety device according to the invention in a washing and centrifuging machine is used, the switch 9 by a programming device (not shown) in such a way be operated so that the switch 9 assumes the position 10-11 when the machine is centrifuging. The polarization of the core 1 is then in such a way that the core is attracted to the magnet 3 and an element 13 (Fig. 2) is pushed between the hook 14 and the hook for 15, thereby locking the door in the closed position.
Wenn die Maschine in der Waschphase wirksau ist und die Waschtrommel sich mit niedriger Geschwindigkeit dreht, ist der Schalter 9 in der Stellung 10-12 geschlossen, wobei die Polarität des Kernes 1 derart ist, dass er von dem Magneten 4 angezogen und die Tür 15 erriegelt ist.If the machine is efficient in the washing phase and the Washing drum rotates at low speed, the switch 9 is closed in position 10-12, the polarity of the core 1 being such that it is attracted by the magnet 4 and the door 15 is locked.
Diese Sicherheitsvorrichtung hat ferner einen Mikroschalter, der die Speisespannung des Maschinenmotors unterbrechen kann, in welchem Falle die Trommel praktisch unmittelbar angehalten wird, wenn die Tür von dem Gebraucher geöffnet wird, während die Maschine in dem WaschzylkluB wirksam ist, wobei weiter eine bekannte Vorrichtung vorgesehen ist, durch welche der Motor lediglich mit der hohen Zentrifugiergeechwindigkeit anlassen kann, wenn die Tür verriegelt ist.This safety device also has a microswitch, which can interrupt the supply voltage of the machine motor, in which case the drum is stopped practically immediately when the Door is opened by the user while the machine is operating in the washing cylinder, furthermore a known device is provided by which the motor can only start at the high centrifugation speed when the door is locked.
Wenn infolge einer Störung des Netzes die Tür 15 nicht von dem Elektromagneten entriegelt werden kann, wird die Entriegelung dadurch bewerkstelligt, dass der Kern 1 mittels einer Stange 16 verschoben wird, auf der ein Anschlag 17 angebracht ist, der mit einer Plattt 18 zusammenwirkt und mittel· einer Feder 19 vorerbestimmter SpannungIf the door 15 is not due to a fault in the network the electromagnet can be unlocked, the unlocking is accomplished in that the core 1 is displaced by means of a rod 16 on which a stop 17 is attached, which with a plate 18 cooperates and means of a spring 19 predetermined tension
