ものである。In order to solve this problem, a conventional vending machine operates only a part of a heating device without operating all of the heating device at the same time, and uses an on / off signal of a thermostat provided in a cooling compartment. To control the operation of the heating device. That is, when the temperature of the cooling chamber is around a predetermined temperature, the thermostat provided in the cooling device is controlled to be turned on and off almost periodically by using an on / off signal of the thermostat of the cooling device. Is what you do. Specifically, every time the thermostat is turned on from off to start operation of the cooling device, the operation of the heating device in operation is stopped, and the heating device in operation is stopped.
