Abstract: An ice making machine has round receiving groove in the isolating plate for receiving the condensing basin, the condensing basin will not move horizontally. By the limiting groove with a plurality of limiting rods which is engaged with the two ears, it is avoided that the condensing basin rotates unwillingly. Especially, a single layer ice brick can be made by using the inner basin with the outer basin. Or the use of the core basin with the outer basin, an inner layer ice brick c is made firstly. Then the use of the inner basin with the outer basin cause an inner ice brick d is made. Therefore, a double layer ice brick is formed with two odors or two colors. By use of the inner basin and the outer tube, the ice brick can be easily taken out.
