Abstract

PURPOSE:To save electricity of a refrigerator, by electrifying a time limit relay by a closing operation of the first thermoswitch TH, connecting its contact in series with a contact of the second TH whose off-point temperature is lower than that of the first TH, and forcibly stopping the electrification to a refrigerator. CONSTITUTION:At the maximum load of a refrigerator, the first TH2 and the second TH3 always close the contacts, a relay 5 is electrified by the TH2, a contact 8 is closed, a solenoid S4 and a relay 10 are electrified, also a contact 5 is opened, and electrification to a time limit relay 7 is stopped. An electromagnetic valve is opened by electrificatin to S4, a refrigerant is supplied to an evaporator, and it is cooled to a prescribed temperature. When load has decreased below the maximum load, a temperature falls below the prescribed value, TH1 becomes off, the contact 6 is closed, and the relay 7 is electrified. When a prescribed time has elapsed, the relay 7 opens a contact 9 and stops electrification to S4. When load becomes lower, a temperature falls faster than the prescribed value, the contact of TH3 is opened before a contact 9 of a relay DR is opened, and electrification to S4 is stopped.
