[Problem] In a vending machine that cools and sells products, to prevent the sale of products which are not in the appropriate temperature state, even in a case where sold are products which have a suitable temperature range or allowable temperature range that is narrow. [Solution] In the present invention, a vending machine drives a cooling device if a lower-space temperature T1 within a product accommodating chamber has exceeded an upper limit value TSU of a set temperature, and executes a partial cooling operation for cooling, from among a plurality of products accommodated in the product accommodating chamber, products on the lower side (S1 to S2). Thereafter, when the lower-space temperature T1 falls to a lower limit value TSL of the set temperature, the vending machine executes an overall cooling operation for cooling the entirety of the plurality of products (S3 to S4). Further, if during execution of the overall cooling operation the lower-space temperature T1 exceeds the upper limit value TSU of the set temperature, the vending machine suspends the overall cooling operation and executes the partial cooling operation (S5 to S6). |
