The present invention relates to a vending machine in which heaters are disposed in both of the storage chambers and the second storage chamber, and the first and second storage chambers can be switched to a cooling or heating state, respectively.

(Prior Art) In a conventional vending machine in which the first and second storage chambers separated by an intermediate partition wall can be switched to a cooling or heating state, a vending machine is installed in the first chamber. The first storage compartment is switched between the cooler and the first heater using a changeover switch installed outside the storage compartment, and the first storage compartment is switched to a cooling or heating state. A shutter provided inside the refrigerator is opened and closed to switch the path of circulating air, and a switch linked to the movement of the shutter turns on and off the second heater in the second storage room. The second storage chamber is switched to a cooling or heating state.

(Problem to be Solved by the Invention) In such a conventional configuration, since there is no cooler in the second storage compartment, when the second storage compartment is selected to be in the cooling state, the first storage compartment is also The cooling state must be selected. However, if the user accidentally switches the first storage compartment to the heating state using a switch outside the refrigerator,
There is a possibility of an erroneous operation in which the shutter could be switched, such as when placing the second storage chamber in the cooling state. In this switching state, a part of the warm air generated in the first storage chamber flows into the second storage chamber, so the inside of the second storage chamber is not cooled, and the second storage chamber is not cooled. Since the second heater is in a power-off state, the second storage chamber is not sufficiently heated.

Therefore, an object of the present invention is to prevent the shutter for opening and closing the communication port provided in the partition wall from being opened when the first storage chamber is selected to be heated, thereby preventing the user from operating it incorrectly. We provide a vending machine that allows you to avoid this.
