PROBLEM TO BE SOLVED: To provide an automatic vending machine that refrigerates and sells products in which, even in the case of selling products having a narrow optimal temperature range or an allowable temperature range, products which are not in an optimal temperature state are prevented from being sold.SOLUTION: An automatic vending machine, in the case where lower space temperature T1 in a product storage becomes higher than the upper limit value TSof a preset temperature, drives a refrigerating apparatus to execute a partial refrigeration operation for refrigerating products in a lower area out of a plurality of products housed in the product storage (S1→S2). Then, when the lower space temperature T1 drops to the lower limit value TSof the preset temperature, the automatic vending machine executes a whole refrigeration operation for refrigerating all of the plurality of products (S3→S4). Further, in the case where the lower space temperature T1 becomes higher than the upper limit value TSof the preset temperature while executing the whole refrigeration operation, the automatic vending machine stops the whole refrigeration operation and executes the partial refrigeration operation (S5→S6).SELECTED DRAWING: Figure 4 |
