Claims

[Scope of utility model registration request]

A cooling system in which cold or warm air blown from below the column is ventilated into the storage compartment and circulated below the column via a suction duct to cool or heat the products stored in the column.・
In the vending machine that also serves as a heating device, the duct is provided with a first suction port located at approximately the middle height of the column, and a second suction port located above the first suction port, and A rotary damper is provided that alternately switches the ventilation of each suction port, and the rotary damper includes a bias spring that biases the damper in the direction of closing the first suction port, and a bias spring that biases the damper in the direction of closing the first suction port. A vending machine comprising: a drive spring made of a shape memory alloy that urges the rotary damper in the closing direction of the second suction port against the biasing force of the bias spring.
