Abstract: PURPOSE:To provide a controller for a freeze refrigerator that eliminates a rise in temperature of foods due to insufficient precooling or due to an excess of precooling by carrying out precooling right before defrosting according to the largeness of thermal load to the foods in the refrigerating member. CONSTITUTION:The temperature in the subject refrigerating refrigerator is detected by a temperature sensor 21, and when a cumulative time counter 22 for the operation of a compressor counts a set time, the cooling time from the standard value of a second-standard circuit 25 to the standard value of a fourth standard circuit 32 is measured by a cooling time measurement means 31. From this cooling time and the ambient temperature detected by an ambient temperature sensor 30 a fuzzy-theoretical calculation is carried out based on a control rule taken out from a memory 34 by a fuzzy inference processor 33 to determine the time of precooling and precooling time is set by a time setting means 35 for the timer.

Abstract: PURPOSE:To prevent the erroneous heating of a can which should not be heated by judging the can to be heatable at the time of detecting the presence of a mark by the majority of first and third mark detectors or second and third mark detectors and heating only the drink can judged to be heatable. CONSTITUTION:A mark detecting means 18 consists of a first mark detector group 18-a consisting of first mark detectors (18-1) to (18-3), a second mark detector group 18-b consisting of second mark detectors (18-4) to (18-6), and a third mark detector group 18-c consisting of third mark detectors (18-7) and (18-8). The can is judged to be heatable when the majority of first and third mark detectors or second and third mark detectors detects the presence of the mark, and only the drink can judged to be heatable is heated. Thus, a safe induction heating controller for the automatic vending machine is obtained where drink of high viscosity or aerated drink is not erroneously heated even when the drink is erroneously thrown-in.

Abstract: PURPOSE:To enable safe and low-priced automatic sale without danger by discriminating whether heating can be executed or not, and the capacity of contained drink from a bar code attached on the wall of the can, and heating only the can drink, which can be heated, only for time corresponding to the capacity of the contained drink. CONSTITUTION:A heat control means 19 inputs information such as possibility of heating or the capacity of the contained drink, etc., which is discriminated from the bar code on the lid part of the can to be discharged at the next heating and selling time in a commodity for heated sale housing device 5, from a bar code discriminating means 18. Next, when a heated sale witch 10 is turned ON, a discharging means 7 for heated sale is operated and the can drink is guided into a heating coil 12. When the can is discriminated suitable for heating by a bar code discrimination signal 18 inputted in advance, continuously, the capacity of the contained drink is samely discriminated and induced heating is executed only for the time corresponding to the capacity. When heating is finished, a heat ending and conveying means 20 is operated to convey the can drink to a selling port and the heated sale is completed. Thus, erroneous heating is prevented and the capacity is detected at low cost.
