JPH06131540A - Control device for automatic vending machine - Google Patents

Abstract

PURPOSE:To change temperature in a stock in accordance with outside air temperature by providing this control device with a intra-stock temperature setting means, an outside air temperature detecting means and a temperature changing means, detecting the outside air temperature and changing set temperature in accordance with the detected temperature to drive an automatic vending machine. CONSTITUTION:An intra-stock control temperature, a date, etc., are previously set up by a keyboard 2. Outside air temperature is detected by a thermistor 10 and whether the detected outside air temperature is >=30 deg.C or not is judged. In the case of >=30 deg.C, the machine is driven at a prescribed temperature lower than a normal set temperature, and in the case of <30 deg.C, whether the outside air temperature is <=5 deg.C or not is judged. In the case of <=5 deg.C, the machine is driven at a prescribed temperature higher than the set temperature, and in the case of >5 deg.C, the machine is driven at the set temperature. Thus cooling/ heating control appropriate for the outside air temperature is executed and a suitable merchandise can be vended to a customer requiring a cooled merchandise at a hot outside air temperature and a hot merchandise at a cold temperature.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a controller for a vending machine which controls cooling and heating in each compartment of the vending machine.

[0002]

2. Description of the Related Art In FIG. 4, reference numeral 1 is a main body of an automatic vending machine, 2 is a keyboard for performing various settings such as temperature setting in the automatic vending machine, and 3 is a key. In the conventional cooling and heating control of the vending machine having such a configuration, the set temperature in each compartment was constant throughout the year.

[0003]

As described above, in the conventional control, the set temperature in each compartment is constant throughout the year regardless of the outside air temperature. That is, during the daytime when the outside temperature is high,
The set temperature was constant even when it was low at night. Therefore, it is impossible even if the user wants to taste cooler food when it is hot, and it is impossible even if he wants warmer food when it is cold.

In view of the above problems, it is an object of the present invention to provide a controller for an automatic vending machine, which changes the set temperature in each store according to the outside air temperature.

[0005]

In order to solve the above-mentioned problems, a control device for a vending machine according to the present invention, as shown in FIG. 1, includes a keyboard for inputting data such as a temperature inside the refrigerator,
In a vending machine having a main controller that controls the temperature inside the refrigerator based on the temperature set value of the keyboard and the signal from the temperature sensor inside the refrigerator, a means for setting the temperature inside the refrigerator and an outside air temperature detection for detecting the outside air temperature. Means and temperature changing means for changing the set temperature according to the outside air temperature are provided, and the inside temperature is controlled according to the changed inside temperature.

[0006]

According to the present invention, the outside temperature is set by the keyboard, and the outside temperature is detected by the thermistor to determine whether the outside temperature is 30 degrees or more. In the above cases, the operation is performed at a temperature lower than the normal set temperature, in the following cases, it is determined whether the outside air temperature is 5 degrees or less, and in the following cases, the operation is performed at a temperature higher than the set temperature.

[0007]

2 is a block diagram showing the structure of an embodiment of the present invention. In the figure, the same reference numerals as those in FIG. 4 indicate the same members. Reference numeral 4 is a master device having a CPU and having a determination function and outputting a command for controlling the vending machine. Reference numeral 5 is a control device for controlling members such as cooling and heating. 6 is a compressor for cooling the inside of the refrigerator. Reference numeral 9 is a heater for heating the inside of the refrigerator, and 10 is a thermistor attached to a part of the main body of the vending machine to detect the outside temperature.

In such a configuration, the keyboard 2 is used to set the control temperature in the refrigerator, the date, and the like. The operation of the apparatus having the above configuration will be described below with reference to the flowchart of FIG. First, the thermistor 10 detects the outside air temperature (step S1), and then determines whether the outside air temperature is 30 degrees or more (step S2). In the above case, the operation is performed at a predetermined temperature lower than the normal set temperature (step S3). In the following cases, it is determined whether the outside air temperature is 5 degrees or less (step S4). In the following cases, the operation is performed at a predetermined temperature higher than the set temperature (step S5). In the above case, the operation is performed at the set temperature (step S6).

When the temperature is 30 degrees or more, the temperature can be lowered depending on the temperature exceeded, and when the temperature is 5 degrees or less, the temperature can be raised according to the temperature difference from the set temperature.

[0010]

According to the present invention, by detecting the outside air temperature and changing the set temperature in accordance with the temperature to operate, the cooling and heating control for adapting the inside temperature to the outside air temperature is possible, It is possible to sell products suitable for customers.
