As described above, according to the present invention, in a vending machine in an installation environment with a small sales volume, a part of a product storage device is moved by moving a wind path shielding plate downward by operating a switch. As a result, the product is partially cooled and partially heated so that only a part (downward) of the product is at a suitable temperature for sale, and the operation rate of the cooling / heating device is reduced, thereby obtaining an effect of reducing power consumption.

Further, by moving the air path shielding plate downward by operating a switch, connecting it to the return duct, and opening the shutter, convection of air occurs in the entire product storage device, so that an automatic installation in an installation environment where the sales volume is very large. By moving the air shield plate up and down by operating the timer means and the setting means, which can respond to sales at the vending machine, during the time when the sales volume is small (for example, late at night), some of the products in the product storage device (downward) ) Only partial cooling / partial heating that is suitable for sale
Cooling and heating can be performed during a time period when sales volume is large (for example, during the daytime), and power consumption can be reduced while maintaining a temperature suitable for sales. In addition, when the number of sales per day is less than a predetermined regulation, the air path shielding plate is controlled and moved downward, so that when the sales volume is small, partial cooling and partial heating are performed. It is possible to automatically reduce the power consumption of the vending machine while maintaining an appropriate temperature for the product to be sold. In addition, vending machines installed in department stores and amusement parks,
When there are large differences in sales volume on Saturdays and Sundays where people gather and weekdays when there are few people, and on regular holidays, and when the number of sales by day varies greatly, the sales volume by each day is
When the sales volume is low, partial cooling / partial heating is performed when the sales volume is low by controlling the air path shield plate and moving it downward if it is less than the preset regulation, thereby selling products according to the sales situation for each day of the week Thus, it is possible to automatically reduce the power consumption of the vending machine while maintaining an appropriate temperature. In addition, vending machines installed in schools and factories are often sold during lunch breaks, and sales are often low at other times. In the case where the sales volume at each time is equal to or less than the preset regulation, the air path shielding plate is controlled and moved downward, so that when the sales volume is small, partial cooling and partial heating are performed. It becomes possible to automatically reduce the power consumption of the vending machine while maintaining the temperature of the product for sale in accordance with another sales situation.

Claims (6)

[Claims] 1. A vending machine for cooling or heating and selling a product, comprising: a main body having a plurality of product storage devices;
A cooling / heating device provided at the lower part of the main body for cooling or heating the products stored in the product storage device, a fan for blowing air cooled / heated by the cooling / heating device, and the product storage device And a space provided above the return duct provided at a position behind the return duct, and a space distance between the return duct and the return duct can be varied. The vertical direction of the back of the product storage device and the return duct is closed. An air path shielding plate, a driving device that moves the air path shielding plate up and down to change the distance in the space, and a switch that is connected to a power supply circuit to the driving device and that turns on and off power supply to the driving device. A vending machine control device comprising: A shutter for opening and closing the return duct in a vertical direction, a spatial distance between the shutter and the return duct being variable, an air path shielding plate having a closed rear surface of the product storage device, and a driving device for opening and closing the shutter. 2. The vending machine control device according to claim 1, further comprising: a switch connected to a power supply circuit for the driving device, for turning on and off power supply to the driving device. 3. A driving device for moving a wind path shielding plate up and down to vary a spatial distance from a return duct, a power supply circuit for supplying power to the driving device, and a timer means for measuring a current time. Storage means for storing a time for controlling the driving device, setting means for setting and inputting the control time, and turning on and off power supply to the driving device.
The control device for a vending machine according to claim 1, wherein the control device is configured to automatically control the driving device by comparing a control time stored in advance with a current time. 4. A driving device for moving a wind shield plate up and down to change a spatial distance from a return duct, a power supply circuit for supplying power to the driving device, A sales control circuit for outputting a sales signal, timer means for measuring the current time, the number of operating days counting the number of operating days, the number of sales counted by the sales signal from the sales control circuit, and a sales regulation constant.
