Title:
DEEP FREEZING REFRIGERATOR
Document Type and Number:
Japanese Patent JPH07218087
Kind Code:
A
Abstract:

PURPOSE: To realize a deep freezing refrigerator having a vegetable storage chamber in which preservability of green fruit to suffer from low-temperature defect can be enhanced.

CONSTITUTION: A vegetable storage chamber B in which a vessel wall in direct contact with cold gas for cooling is formed of a heat insulator 19 is so provided partly in a conventional vegetable chamber as to be always set to a higher temperature than that of the chamber. A moisture regulating sheet 17 for holding humidity in the chamber B constant and a catalytic filter 18 for regulating atmospheric gas are further arranged partly on the vessel wall. The chamber B is not limited to the existing chamber, but can be provided independently at a predetermined position in a refrigerant. Thus, the chamber is held at 8-10°C adapted to preserve green fruit to suffer from low-temperature defect, and its shelf stability life can be prolonged twice-three times as large as the case of the conventional chamber at a low temperature.
