Title:
AUTOMATIC ICE MAKING DEVICE
Document Type and Number:
Japanese Patent JPH051870
Kind Code:
A
Abstract:

PURPOSE: To permit the production of ice, high in transparency and not containing impurities, quickly by a method wherein a feed water tank, defined by a heat insulating layer and equipped with a heater as well as a water temper ature sensor, an oscillator oscillating the feed water tank, and a water reserving pan reserving water from the feed water tank, are provided in one division of a refrigerating chamber.

CONSTITUTION: The predetermined amount of water in a feed water tank 36, which is maintained in a condition immediately before freezing by a water temperature sensor 63, a heater 62 and an oscillator 65, is supplied into an ice making pan 16 through a water reserving pan 39 and a water supplying tube. One directional freezing effect from the surface of water downward by cold air in a freezing chamber is effected by the heat insulating effect of a heat insulating tank 9 and heating effect from a lower surface by the heater 62. Subsequently, when the thickness of ice becomes a proper value, the driving device 23 of a first supporting shaft 21 is operated to pivot the ice making pan 16 and drop the ice onto a water cutting pan 20. Water, containing gas constituents and high concentration of impurities but not frozen yet, is discharged through a lower discharging pan 29 and a drainage pipe 30.
