Abstract

Dispositivo di controllo dei cicli di lavaggio e di risciacquo per macchina lavastoviglie di tipo industriale, comprendente una vasca di lavaggio (4), due coppie di bracci di spruzzo (5, 6) raccordati nel circuito idrico della macchina, trasduttori di misura (19) atti a rilevare la velocità di rotazione dei bracci (5, 6) per segnalarne il funzionamento attraverso un dispositivo indicatore (22 o 27), collegato con l'unità di controllo elettronica (18) che comanda i diversi cicli operativi della macchina. Dispositivo comprendente ulteriori trasduttori di misura (23) inseriti nel circuito idrico per rilevare il flusso del liquido di lavaggio o dell'acqua di risciacquo circolante, trasduttori che sono collegati con l'unità di controllo (18) per segnalare, attraverso essa ed il dispositivo indicatore (22 o 27), il passaggio della quantità di liquido attraverso le condutture del circuito idrico, e quindi il funzionamento corretto o meno del circuito stesso.Washing and rinsing cycle control device for industrial type dishwashing machine, comprising a washing tank (4), two pairs of spray arms (5, 6) connected in the water circuit of the machine, measuring transducers (19) suitable for detecting the rotation speed of the arms (5, 6) to signal their operation through an indicator device (22 or 27), connected with the electronic control unit (18) which controls the different operating cycles of the machine. Device comprising further measuring transducers (23) inserted in the water circuit to detect the flow of the washing liquid or the circulating rinsing water, transducers which are connected with the control unit (18) to signal, through it and the device indicator (22 or 27), the passage of the quantity of liquid through the pipes of the water circuit, and therefore the correct or not correct functioning of the circuit itself.
