Title:
AUTOMATIC VENDING MACHINE
Document Type and Number:
Japanese Patent JP3886190
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To accelerate the cooling speed of a product housing chamber and to reduce heat leakage between the respective product housing chambers.
SOLUTION: Under a condition that the detected temperatures of respective item temperature sensors are higher than a predetermined upper limit reference temperature Tp, respective solenoid valves are controlled so as to supply a coolant to the higher cooler of the cooler for a left chamber and the cooler for a right chamber when the temperature difference of respective cooler temperatures is more than a prescribed temperature range and the solenoid valves are controlled so as to supply the coolant to both coolers when the temperature difference is smaller than the prescribed temperature range (S3-S7). Then, the temperatures of the cooler for the left chamber and the cooler for a middle chamber are observed and the similar control is performed (S8-S12).
