Abstract

PURPOSE:To prevent lumps of ice from being melted wastefully by quickly separating the lumps thereof from ice-producing members, by a method wherein a pair of the ice-producing members with a plurality of slender projections thereon are connected with pins to be caulked, and both ends of each of the pins caulked are projected on the surface of each of the members. CONSTITUTION:When an ice-producing process is finished, a solenoid valve 22 for supplying water is opened and the water for separating ice is sprayed on the rear face of each of ice-producing members 3, 4 through water-spraying holes 21A, 21B on a water-spraying device 21 for separating the ice. At the same time, a solenoid valve 15 for hot gas is opened, and a refrigerant with high temperature is circulated in a cooling pipe 9. In this way, the ice-producing members 3, 4 are heated, and it is released that lumps of ice are in close contact with ice-producing surfaces 3A, 4A. At this time, the horizontal movement of the lumps 2 of the ice caused by the surface tension of water is prevented by the action of projections 10A, 10B on both end parts of each of pins 10 caulked. In addition, the lumps 2 of the ice separated from recesses 5, 6 do not fall in the state of being in contact with ice-producing surfaces 3A, 4A by the action of the projections 7, 8, but the lumps 2 are quickly separated from the ice-producing members 3, 4 and fall into an ice-storing part.
