Title:
CONTROL DEVICE FOR FREEZER REFRIGERATOR
Document Type and Number:
Japanese Patent JP3193923
Kind Code:
B2
Abstract:
PURPOSE: To perform delicate regulation of temperature, in a freezer refrigerator capable of freezing, refrigerating, and storing foods.
CONSTITUTION: Degree of increase of temperature computing means 32 are respectively disposed in a freezing chamber and a refrigerating chamber to compute the degree of the increase of temperature in a chamber and an open air temperature detecting means 31 to detect an open air temperature. A fuzzy inference processor 34 performs fuzzy logic computation based on the degree of the increase of temperature, an open air temperature, and a control rule fetched from a memory 33 to determine the reduction range of a set temperature, and based on the reduction range, a set temperature is regulated by a set temperature computing means, and a compressor, a fan, and a motor- operated damper are controlled.
