PURPOSE: A temperature controller of a vending machine is provided to simplify the structure of the temperature control device while maximizing the efficiency of refrigeration, thus shortening a time required to design the device. CONSTITUTION: The vending machine has a can rack for allowing plural beverage cans to be stacked over and over again, and an automatic temperature adjustment device installed under the can rack. The automatic temperature adjustment device is provided with two short circuit contact points(30) inside a temperature detecting member(10), and a shape memory alloy member(20) of wire shape between the contact points. The temperature controller is provided at the side of the automatic temperature adjustment device so as to control an interior temperature of the vending machine according to a signal produced by the short circuit of the contact points due to the shape variation of the shape memory alloy member. |
