It is possible to absorb fluctuations in the temperature in the refrigerator and control the temperature of the product so that it does not become defective.

Further, by storing the temperatures of the cooling temperature detecting device and the heating detecting device as needed, the temperature of the cooling temperature detecting device and the temperature of the heating detecting device can be corrected due to the difference in the installation condition of the vending machine. If the temperature sensor for cooling is abnormal and the cooling device is controlled by the temperature sensor for heating, the installation condition may be direct sunlight outdoors or other vending machines may be crowded. In such a case, it is possible to absorb fluctuations in the internal temperature due to differences in the installation environment, and control can be performed so that the product does not become a defective product.

Further, even when the temperature detecting device for cooling is abnormal and the temperature of the temperature detecting device for cooling and the temperature detecting device for heating vary widely and it is difficult to obtain consistency, the temperature detecting device for heating may be set to a predetermined temperature or more. Since the cooling device is detected and the cooling device is operated and the cooling device is operated for a predetermined time by the timer device, fluctuations in the internal temperature can be absorbed, and the temperature of the heating detection device that does not become a defective product has large temperature variation. The product can be prevented from freezing.

When the cooling temperature detecting device is abnormal, the heating temperature detecting device detects the predetermined temperature or more and operates the cooling device, and the timer device operates the cooling device for a time set for each outside air temperature. Therefore, fluctuations in the internal temperature due to changes in the outside air temperature can be absorbed, and control can be performed so that the product does not become defective in temperature.

Further, when the cooling temperature detecting device is abnormal, the cooling device is operated by the heating temperature detecting device, and even when the operating condition is switched by the cooling / heating switching device, the cooling and heating operating conditions of the plurality of storage chambers are changed. Since the cooling device is operated for a time set in accordance with the combination of the above, fluctuations in the internal temperature due to the cooling and heating operation of the vending machine can be absorbed, and control can be performed so that the product does not have a defective temperature.

When the cooling temperature detecting device is abnormal, the heating temperature detecting device detects the predetermined temperature or more and operates the cooling device, and the timer device operates the cooling device for a predetermined time, so that the automatic selling is performed. Fluctuations in the internal temperature due to changes in the sales volume of the machine can be absorbed, and control can be performed so that the product does not become a defective product.
