Abstract
Disclosed is a mechanism for detecting completion of ice formation and for preventing such opacification of ice pieces in an ice making machine, in which a multiplicity of freezing fingers formed on the lower surface of a freezing base plate are dipped in the water supplied to a freezing chamber defined in a water tray to carry out a freezing operation and form inverted dome-shaped ice pieces gradually around the freezing fingers; characterized in that the mechanism consists of a rocking plate which is rocked with respect to the freezing fingers by a rocking means; and a position detector which is actuated when a predetermined size of ice pieces are formed around the freezing fingers, and the rocking plate is brought into contact with these ice pieces. In this ice making machine, completion of formation of ice pieces around the freezing fingers is designed to be detected easily and securely by the signal from the position detector, and also transparent ice pieces of high commercial value free from opacification can be formed, while opacification of ice pieces to be formed around the freezing fingers can effectively be prevented since the water to be frozen in the water tray is fully agitated by the rocking motion of the rocking plate having formed thereon a multiplicity of through holes and/or side walls also having such through holes.
