disposed at the forward end of the mold 12 in addition to cycling the ejector 20 control 24 further automatically provides for refilling the mold with water for subsequent further ice piece formation therein for a detailed description of the operation of the control 24 reference may be had to the hereinbefore identified u s pat no 3 276 225 mold 12 defines a plurality of upwardly open cavities 26 in which ice pieces 14 are formed the water from which the ice pieces are formed is delivered to mold 12 by means of an inlet structure 28 that empties into the mold 12 and is supplied with water by a supply tube not shown that is operated by a solenoid valve not shown it will be understood that the valve is connected to a suitable source of water under pressure for delivery of the water to the water inlet structure 28 with reference to fig1 3 the icemaker more specifically comprises a metal mold 12 with a tray structure having a bottom wall 30 front wall 32 and back wall 34 a sheathed electric resistance heating element 36 is positioned by pressing it into the bottom wall 30 to heat the mold 12 during the ejection operation to slightly melt the ice pieces and release them from the mold cavities 26 thus aiding in the ejection operation a plurality of partition walls 38 extend transversely across the mold to define with the above indicated tray walls the cavities 26 in which the ice pieces 14 are formed each of the partition.
