Abstract

Dispositivo di bloccaggio della porta per macchine lavatrici o asciugatrici di biancheria, comprendente un tradizionale attuatore elettromeccanico (4) con elemento bimetallico per l'apertura ritardata della serratura (86) della porta, una pluralità di componenti operativi (14, 15, 16, 17) ed un microprocessore elettronico (8) incorporante un circuito di sicurezza per il consenso all'apertura della porta soltanto al raggiungimento di valori di sicurezza prestabiliti della temperatura del liquido di lavaggio (o dell'aria d'asciugatura, nel caso di macchine asciugatrici), del livello del liquido di lavaggio e della velocità di rotazione del cesto delle macchine. Dispositivo provvisto inoltre di un pulsante elettrico (5) collegato col microprocessore (8) e atto e consentire, attraverso il controllo del microprocessore stesso, il comando dell'apertura porta tramite una camma (90) di un selettore rotante (64) che aziona una corda (87), collegata una leva (94) fulcrata nella serratura (86) ed agente sul chiavistello (98) della porta, aprendolo quando viene azionato detto selettore rotante (64). Dispositivo di tipo semplice ed affidabile, utilizzabile particolarmente nelle macchine sprovviste di maniglia per l'apertura porta.Door locking device for laundry washing or drying machines, comprising a traditional electromechanical actuator (4) with a bimetallic element for delayed opening of the door lock (86), a plurality of operating components (14, 15, 16, 17 ) and an electronic microprocessor (8) incorporating a safety circuit for consenting to open the door only upon reaching pre-established safety values of the temperature of the washing liquid (or of the drying air, in the case of drying machines) , the level of the washing liquid and the rotation speed of the machine drum. Device also provided with an electric button (5) connected to the microprocessor (8) and able to allow, through the control of the microprocessor itself, the command to open the door by means of a cam (90) of a rotary selector (64) which activates a rope (87), connected a lever (94) pivoted in the lock (86) and acting on the bolt (98) of the door, opening it when said rotary selector (64) is activated. Simple and reliable device, particularly usable in machines without a handle for opening the door.
