DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for performing energy saving control of loads such as a fluorescent lamp, a refrigerator and a heater in a vending machine.

[0002]

2. Description of the Related Art For energy saving operation of a vending machine, conventionally, a time for stopping the load within one day is determined in advance, and control for turning off each load is performed during that time. For holidays that stop the load all day,
By looking at the calendar, for example, a schedule for one month was set.

[0003]

However, in the conventional energy saving control, the load is turned off only for a predetermined time period within one day.
As a result, energy was saved only for a few hours, such as at night. In addition, the work of setting a schedule in advance for a holiday is troublesome, and there is a waste that the power supply to the load is continued for a long time despite no sale at all on a special holiday such as a workplace or a school. . Accordingly, an object of the present invention is to provide an energy saving control device for a vending machine which can perform energy saving operation flexibly according to the sales situation and does not need to be set in advance even on holidays.

[0004]

In order to achieve the above object, the present invention provides means for setting a start time and an end time of a sales sampling time within one day, and whether or not there is sales within the sampling time. means for sensing, said sales
When the start time of the selling sampling time comes,
When a specific load is energized and the detection means detects that there is no sales, the sales sampling is performed.
From the end time of the time until the next start time shall be provided with control means for stopping the load.

[0005]

The operation status of the vending machine is determined based on the presence or absence of sales within a preset sales sampling time, and if there is no sales, the load is stopped until the start time of the next sales sampling time. The sales sampling time is preferably set once a day by selecting a time zone in which the vending machine is used first in a day, but may be set a plurality of times including other time zones. . As a result, fine energy saving control according to the sales situation can be performed, and energy saving operation is automatically performed even on holidays when the vending machine is not used all day.

[0006]

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, reference numeral 1 denotes a main control unit which controls the entire vending machine, checks the deposit data from the deposit unit 4 against the set price of the product, and unloads the product in the column where the product selection push button 5 is pressed. The product is sold by operating the product unloading mechanism 7 via the control unit 6, the input data from the keyboard 3 is stored in the storage unit 2, the fluorescent lamp 9, the refrigerator 10, and the heater are controlled via the load control unit 8. Loads such as 11 are O
N, OFF control. The start time and the end time of the sales sampling time for checking the presence or absence of sales in order to perform energy saving control are set and input from the keyboard 3 and stored in the storage unit 2. A clock function for counting time is built in the main control unit 1.

The control operation of the energy saving operation in the above configuration will be described below with reference to the flowchart of FIG. First, the mode of the keyboard 3 is checked in step S1, and if the mode is the energy saving setting mode, the start time of the sales sampling time is set in step S2, and then (the end time is similarly set in step S3. If not, go to step S4.

Next, in step S4, it is checked whether or not the sales sampling time has started, and if it is the start time, the loads 9 to 11 are energized in step S5. Thereafter, it is checked in step S6 whether there is a sale, and if there is a sale, it is checked in step S7 whether the sale is within the sales sampling time. If it is within the sales sampling time, a sale flag is set in step S8, and the flow proceeds to step S9. If there is no sale in step S6, or if it is not within the sales sampling time in step S7, the process proceeds to step S9.
go to.

In step S9, it is checked whether or not the end time of the sales sampling time is reached.
In step 10, it is checked whether there is a flag indicating that there is a sale within the sales sampling time. If there is no flag, the loads 9 to 11 are turned off in step S11, and the process returns to step S1. If it is not the end time in step S9, or if there is a flag in step S10, the process directly returns to step S1. In the above embodiment, all the loads 9 to 11 are subjected to the energy saving operation. However, specific loads, for example, the refrigerator 10 and the heater 1
It is also possible to target only one.

[0010]

According to the present invention, if there is no sale within the preset sales sampling time, the load is stopped until the start time of the next sales sampling time.
Detailed energy-saving driving is enabled, and energy-saving driving is automatically performed even in places where there is a special holiday at work or school, without having to make troublesome holiday settings.
