START CONTROL DEVICE OF ELECTRIC REFRIGERATOR

摘要

PURPOSE: To make the size of a generator serving as a power source for a plurality of electric refrigerators smaller. ;CONSTITUTION: An electric refrigerator 11(12,13), when the internal temperature thereof has exceeded a set temperature, outputs supply voltage from a generator 15 from an operation start output terminal 11b. A control means 20 is composed of relay blocks 21,22,23 and a timer block 24 and outputs, when supply voltage is outputted from a plurality of electric refrigerators, supply voltage to an operation start input terminal 11c of electric refrigerator in the order of priority. As a result, a plurality of electric refrigerators are started at predetermined time intervals, so that generators of smaller size can be used.;COPYRIGHT: (C)1993,JPO&Japio
