Abstract

PURPOSE: To provide a freezing apparatus wherein switches operating a longest time-setting timer and other timers at temperatures over a set temperature are arranged in series and are operated in parallel by timers, defrosting being carried out based on defrosting instructions by a timer, and thus erroneous operations and a decrease in refrigerating power being eliminated.
CONSTITUTION: If the temperature of air in a freezing apparatus is over a set point as the high temperature side, an output contact 15b is closed, long and short time timers 17, 18 being operated in parallel by timers. If a fixed time is passed, an output contact 18a of the short time timer 18 is closed, an assistant defrosting relay 19 being actuated, and an electromagnetic valve 13 being closed. Then, a compressor 7 is stopped, defrosting operations being initiated by circularizing a defrosting heater circuit 11, and the timers 17, 18 standing to wait for the next timer time. Also, if frost adhering to an evaporator is molten, and a defrosting finish-detecting thermostat is actuated, the defrosting assistant relay 19 returns with a decrease in the power, and the freezing apparatus starting operation, and the timers 17, 18 starting clocking. Thus, defrosting corresponding to the amount of frost adhesion is ensured.
