Therefore, if the cold temperature display device is left in a stopped state for a long period of time, the grease injected into the bearings, reduction gears, etc. of the drive motor 20 will solidify and will not start smoothly when the next sales mode is changed. There is a risk.

Therefore, in the present invention, the cold / warm display device is made to perform a test operation each time the front outer door is opened and closed to replenish the vending machine or collect money.
For this reason, the door switch 2 provided on the door as shown in FIG.
The operation signal of No. 5 is fetched into the controller 21, and the drive motor 20 is controlled by a command from the controller 21 so as to rotate the cold temperature display drum 7 once every time the door is opened and closed (the cold temperature display pattern is not changed).

The operation for switching the cold temperature display described above is shown in the flow chart of FIG.

[0031]

As described above, according to the cold / warm display device of the present invention, the cold / warm pattern displayed on the display window of the display table can be set in accordance with each sales mode set inside the vending machine. The setting / changing mode does not require the troublesome work of replacing the cold / cold pattern display body with the display stand each time like the conventional cold / cold display device, and the display of the cold / hot pattern can be done by simple manual operation or automatic operation. The serviceability can be improved by changing the settings according to.

Further, in particular, according to claim 5 of the present invention, as a rotary operation mechanism, a drive motor is transmission-coupled to the cold / warm display drum, and the cold / warm temperature is linked with a sales mode switching command for switching the product storage to cooling / heating. By controlling the drive motor to rotate the display drum to the designated pattern display position, the cooling / heating operation is switched in the inside of the refrigerator in response to a command from this switch simply by performing the switching operation of the cooling / heating switching switch. At the same time, it is possible to automatically switch the display of the cooling / heating pattern, and it is possible to prevent the display error of the cooling / heating pattern seen in the manual operation method.

In this case, when the selling mode is changed, the pattern display of "preparing for hot" or "preparing for cold" is displayed corresponding to the selling mode after switching the cold / heat display drum first. If the drive motor is controlled so that it rotates to the position and switches to the "hot" or "cold" pattern display position after a certain period of time, the goods stored in the store are cooled to the appropriate temperature for sale, or rise until heated. During the time, the customer can be warned that cold and hot preparations are in progress, and when the outer door of the vending machine is opened or closed, as in claim 12.
If the drive motor is controlled to perform a test operation by rotating the cold / warm display drum once based on the door switch operation signal, it will be injected into the drive mode bearings, reduction gears, etc. when changing the sales mode several times a year. This prevents problems such as grease that has solidified and ceased to operate smoothly.
