ABSTRACT:
An ice-making machine includes a hopper (10) which is provided with means for automatically switching the machine off when the ice collected in the hopper rises to a predetermined level. The hopper comprises a cup-shaped bowl (14) covered with a flanged collar (24) slidable within the bowl. The collar (24) in turn is covered with a lid (32) which is press fitted onto its upper cylindrical part (28). Magnetic switches (38 and 40) are attached to collar (24) and magnetically sensitive contacts of the switches are mounted in bowl (14). The switches are connected in series in the circuit of the drive motor of the ice-making machine and are normally closed. When ice fills the bowl to a predetermined level, the lid and the collar, which is rigidly connected to the lid, are lifted, thereby breaking the contacts and turning the ice-making machine off. When, after consumption of ice, its level in the bowl is lowered, the lid and the collar descend, closing the contacts and reenergizing the ice-making machine.
