Claims

[Scope of Claim for Utility Model Registration] A product rack into which products are put into the rack through at least one product input port opening at the upper part of the front surface, a product storage room that accommodates the product rack, a front door, and the product storage room. an insulating inner door disposed between the product rack and having a product loading window that can be opened and closed at a position opposite to the product loading port of the product rack; and a temperature that maintains the temperature inside the product storage chamber within a predetermined temperature range. In a vending machine equipped with a regulating device, a duct is provided above the product rack, and the duct includes an intake port for sucking air from the product storage chamber, and an air intake port located above the product loading window and arranged in the heat-insulated interior. an exhaust port that opens downward between the door and the product rack, and at least one blower fan that is disposed within the duct and discharges air in the duct from the exhaust port; and an endothermic surface. and a heat dissipation surface, the heat absorption surface and the heat dissipation surface being reversed depending on the direction of the applied current. at least one heat exchange device that performs the exchange; at least one open/close detection switch that detects the open/closed state of the product loading window; and based on the cooling or heating state of the temperature adjustment device and the state of the open/close detection switch, A vending machine characterized by comprising: an energization control means for controlling energization to the ventilation fan and the electronic cooling element.
