(c) Problems to be Solved by the Invention Conventionally, in vending machines that store and sell cigarettes, the cigarettes are stored at room temperature and are not cooled or heated. However, there may be a large temperature difference between the outside temperature and the temperature inside the vending machine storage. For example, this tends to occur in cold regions when the room in which the vending machine is installed is heated, or when the vending machine is installed outdoors.

Therefore, if you open the door to refill cigarettes when there is a large temperature difference, outside air will flow into the storage compartment, which may cause condensation on the product storage shelves and delivery chute, causing product In addition to causing quality deterioration, problems arise in that the products stick to each other and the products stick to the delivery chute during delivery.

On the other hand, if products such as cigarettes or Chofuray F. are stored in high temperature conditions, the quality will deteriorate. Especially in vending machines installed in places exposed to direct sunlight, products such as cigarettes or Chofuray F. This resulted in a decline in quality.

In order to solve this problem, if the inside of the storage is configured to be cooled, dew condensation will easily occur inside the storage due to the inflow of outside air, and dew will form on the products and the delivery chute, resulting in a decrease in the quality of the products. In addition, there is a problem in that the products stick to each other or the products stick together due to delivery short circuits, resulting in defective delivery of the products in the same manner as described above.

For this reason, the present invention provides an air conditioning system for a vending machine that can prevent condensation from occurring within the storage compartment, and will not cause deterioration in product quality or defective delivery.

Since the structure is such that air is blown through the chute and to the suction port provided at the lower end of the opening, it is possible to reliably prevent dew condensation inside the delivery chute, reducing product quality and preventing product delivery failures due to sticking. This has the effect of being able to prevent

In addition, unreleased QJI can be detected by turning on the heater inside the storage compartment and changing the temperature between the temperature inside the storage compartment and the temperature on the cooler side (when a temperature difference of more than a predetermined value does not occur). Since the temperature difference is maintained and the dehumidifying effect of the cooler is maintained, it is possible to prevent condensation from forming inside the storage.Condensation 2. Degradation of product quality and defective delivery due to condensation. This has the effect of preventing

Furthermore, the present invention operates or stops (7) a cooling device provided in the ventilation passage to cool the air circulating in the ventilation passage, the inside of the passage, and the shielded ventilation passage, depending on the temperature inside the storage. In addition to stabilizing the temperature at a predetermined level, when the cooling device stops, the heating device inside the storage can be activated to maintain the temperature difference between the cooler of the cooling device and the inside of the storage, so even when warm outside air flows in, the heating device inside the storage can be activated. Since it is designed to prevent dew condensation in (1), it is possible to prevent deterioration of product quality due to temperature and humidity, and also to prevent defective delivery of products due to dew condensation.
