Refrigerator with cold accumulation system
First Claim
1. A refrigerator having a compartment, comprising:
- a cold accumulation material;
a refrigerating cycle for cooling said compartment and the cold-accumulation material;
means for cooling said compartment by heat transfer between said compartment and said cold-accumulation material;
load detecting means for measuring an amount of a load to be cooled;
clock counting means for generating time data; and
control means for causing said refrigerator to operate in accordance with first, second and third modes of operation wherein in said first mode said refrigerator compartment is cooled by the refrigerating cycle, wherein in said second mode said compartment is cooled by the cold-accumulation material, and wherein in said third mode the cold-accumulation material is cooled by the refrigerating cycle, said modes being carried out in accordance with said time data, the second mode operation having a time duration that is a function of load as determined by the load detecting means.

Abstract
A cold-accumulation type refrigerator having variable length cycle for cooling by means of the cold-accumulation material. The cycle length is a function of refrigerator load. The refrigerator includes a refrigerating cycle to cool a refrigerator compartment and the cold-accumulation material, a load detecting device, such as a room temperature detecting device, to measure an amount of a load to be cooled, clock counting device to generate a time data, and a control device, such as microcomputer. The control device controls the operation of the refrigerator which operates in a first mode (ordinary cooling operation), a second mode wherein the refrigerator compartments are cooled by means of the cold accumulation material and a third mode wherein the cold accumulation material is cooled. The control device controls the time period for second and third mode operation as a function of load to be cooled.
