<p>PURPOSE:To smoothly perform supply and discharge of ice making water to always make possible the production of a solid lump of ice without hollowness in its center part in an ice formed space until the solid lump of ice is formed in the ice forming space by composing the pictured position of holes for supplying and discharging the ice making water drilled on the bottom part of a second ice making chamber of a bad heat conductor. CONSTITUTION:When a first ice making chamber 11 is cooled at the time of ice making operation since a supply and discharge member 71 is composed of a bad heat conductor, a second ice making chamber 12 composed of a good heat conductor has approximately the same temperature as the first ice making chamber 11, but the temperature of the supply and discharge member 71 is a little higher than both the ice making chambers 11, 12 because the supply and discharge member 71 has bad heat conduction. Accordingly, a time for making an ice layer on the upper face of the supply and discharge member 71, a supply hole 71a and a discharge hole 71 is longer than that for making the ice layer in both ice making small chambers 13, 15. Thereby, the supply hole 71a is blocked by the ice layer not to stop the supply of ice making water although a solid globular body is not nearly formed in both the ice making small chambers 13, 15.</p> |
