METHOD AND DEVICE FOR CONTROLLING TEMPERATURE OF REFRIGERATING CHAMBER THROUGH CONTROL OF SPEED OF ROTARY BLADE

摘要

PROBLEM TO BE SOLVED: To provide a temperature control method through control of the speed of a rotary blade and a temperature control device for a refrigerator. SOLUTION: A fuzzy model is constituted to effect inference of an equilibrium speed corresponding to the rotation speed of a rotary blade 20 necessary and optimum to keep an equilibrium of temperature in a refrigerating chamber. An equilibrium speed is calculated by effecting fuzzy inference by a fuzzy model according to the measurements of a temperature change in a given spot in the refrigerating chamber and the rotation speed of the rotary blade is controlled according to the equilibrium speed. This constitution effects accurate inference of the temperature value of each part of the refrigerating chamber only by the less number of temperature sensors 11 and 12, and distributes cold air according to a distance by adjusting the rotation speed of the rotary blade 20 according to an inference position and uniformly keeps temperature in the refrigerant chamber without eccentric concentration of the temperature on the refrigerating chamber to a specified part.
