Refrigerator having chill distribution blade capable of concentrated chill supply to specified position



PROBLEM TO BE SOLVED: To perform concentrated cooling at a specific temperature raised part by controlling a drive motor to supply chill to a high temperature part based on the temperature in a cooling chamber detected by a plurality of temperature sensors disposed therein thereby adjusting a planar horizontal distribution blade disposed in a duct. SOLUTION: A pair of temperature sensors 9a, 9b are disposed in a refrigeration chamber 3 and a horizontal distributor 30 is arranged such that a drive motor turns a horizontal distribution blade through a rotary shaft thus diffusing chill delivered from a chill delivery port 16 in the horizontal direction. At the time of operation, a microprocessor for controlling the drive motor measures the temperature in the refrigeration chamber by means of the first and second temperature sensors 9a, 9b and calculates the temperature difference. When the temperature difference is higher than a specified level, the temperature is compared between the regions being detected by the first and second temperature sensors 9a, 9b, respectively, and the drive motor is stopped under a state where the horizontal distribution blade is directed toward the higher temperature region. According to the arrangement, concentrated cooling at a high temperature part can be realized. COPYRIGHT: (C)1999,JPO
