Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control device for a post-mix beverage vending machine.

Conventional technology Conventionally, when selling syrup drinks in beverage vending machines,
It is sold by diluting concentrated syrup ingredients with drinking water.

An example of the conventional beverage vending machine mentioned above will be described below with reference to the drawings.

FIG. 3 is an explanatory diagram showing a drinking water supply route in a general vending machine. In FIG. 3, 1 is a cup feeding device and 2 is a cup. 3 is Gistern, which temporarily stores water supplied from outside.

4 is a water tank, and the water in the tank is sufficiently cooled. 5 is a sales opening, 6 is a water discharge lever, and 6a is a discharge nozzle. Reference numeral 7 denotes an electromagnetic valve connected to the water dispenser lever 6 to control the discharge of drinking water. 8 is a drinking water cooling pipe.

The operation of the vending machine configured as described above will be explained below.

When the sales operation starts, the cups 2 are carried out from the cup supply device 1 to the sales outlet 6. Then, ice and syrup raw materials are discharged into the cup 2 (not shown in the drawing), and the electromagnetic palguar is opened for a predetermined time, and the sufficiently cooled water in the water tank 4 cools the drinking water cooling pipe 8. The drinking water is discharged from the discharge nozzle 6a into the cup via the water outlet vibro.

Problems to be Solved by the Invention However, in the above configuration, after the sales operation is completed,
When the electromagnetic valve 7 closes, drinking water remains in the water dispenser vibe e. In addition, the wet vibrator 6 is exposed to the outside air.

Therefore, when the sales interval increases, when the outside temperature is high such as in summer,
The temperature of the cooled drinking water in the water dispenser vib θ rose, and the next time sales were held, there was a problem in that the drinking water would be lukewarm.

In view of the above problems, the present invention provides, in any case,
To provide a control device for a beverage vending machine that can supply sufficiently cooled drinking water.

Means for Solving the Problems In order to solve the above problems, the control device for a beverage vending machine of the present invention includes an electromagnetic valve that controls the flow of cooled drinking water through a water tank, a timer, A pipe with a discharge nozzle at the tip is provided on the outlet side of the electromagnetic valve, and a timer is initialized every time a sale is made, and when the timer detects that a predetermined time has elapsed, the electromagnetic valve is opened for a predetermined time. This is how it was done.

Effect of the Invention With the above-described configuration, the present invention can automatically open the electromagnetic valve according to the timer when drinking water remains in the water draining vibrator for a predetermined period of time, and the lukewarm drinking water can be discharged.

EXAMPLE Hereinafter, a control device for a beverage vending machine according to an example of the present invention will be described with reference to the drawings. Incidentally, since the only difference is the control circuit from the conventional one, for convenience of explanation, the explanation will be made using FIG. 3.

In the figure, 11 is a timer, and R8T receives a "H" signal (
When a signal (hereinafter referred to as "H") is applied, the timer is initialized, and when a predetermined time elapses with R5T being an "L" signal (hereinafter referred to as "L"), "H" is output from OUT. 12
is a load control circuit, which drives each load when an input signal is applied. In the embodiment, only a relay for an electromagnetic valve is shown. 13 is a selection switch S1. 14 is an OR element, which outputs "H" when "H" is added to either input. 16 is a relay that controls the electromagnetic valve; 16
' is the relay contact. 17 is an electromagnetic valve.

The operation of the control device configured as described above will be explained below.

First, when the selection switch 13 (Sl) in FIG. 1 is pressed (time t1 in FIG. 2), R'' is input to the OR element 14, R5TFC'H'' of the timer 11 is input, and the timer 11 is initialized. At the same time, the load control circuit 12 turns on the relay 16 and opens the electromagnetic valve 17. As a result, the water in the draining vibrator 6 (FIG. 3) becomes water that has been cooled in the water tank 4, and the water temperature in the draining tube 6 decreases. Next, when no sales are made (the selection switch 13 is not pressed) and a predetermined time T has elapsed (12 o'clock in Figure 2), "H" is output from the OUT of the timer 11 in Figure 1, and the load control circuit 12 turns on relay 16
and opens the electromagnetic valve 17. And timer 11
The output of R3T of the timer 11 is sent via the OR element 14 to R3T of the timer 11.
Input "H" to the timer 11 to initialize the timer 11. By opening the electromagnetic valve 17, the water temperature in the water draining tube decreases as described above. Hereinafter, in FIG. 2, t3. At t4, the selection switch 13 (Sl) is pressed and a sale is made, and at 16:00, no sale is made after t4, and after a predetermined time T, the solenoid valve 17 is activated by the output of the timer 11.
Opening indicates that the water temperature in the water drain lever 6 is lowered.

As described above, by providing a timer that is initialized every time a sale is made and controls the solenoid valve to open if no sale is made for a predetermined period of time, drinking water can be kept sufficiently cool in any case. can be supplied. In addition, there is a method to prevent the sale of lukewarm drinking water by draining the drinking water before the cup is transported to the sales outlet every time the cup is sold, but this method results in frequent draining of the drinking water.
A problem arises in that the drainage bucket provided in the vending machine quickly becomes full of water. The present invention can also solve this problem.

Effects of the Invention As described above, the present invention includes an electromagnetic valve for controlling the flow of cooled drinking water through an aquarium, and a pipe having a discharge nozzle at its tip on the outlet side of the electromagnetic valve. By providing a timer that is initialized every time and opens the electromagnetic valve if no sales are made for a predetermined period of time,
Drinking water remaining in the pipe can be drained at a suitable time, and sufficiently cooled drinking water can be supplied in any case.
