Abstract

PURPOSE:To simply extract a predetermined quantity of bubble by providing a bubble extraction button and control means for opening a valve at a predetermined period for each predetermined time to extract the bubble of drink if the button is pressed. CONSTITUTION:Whether it is a selling mode or a setting mode is checked from a switching signal of a mode changeover switch 9, and if a bubble extraction button 7 is pressed in the setting mode, a CPU 5 counts depressions. Then, end of setting is judged by switching to the selling mode, and valve opening time proportional to the depressions of the button 7 is stored in a memory 6. When it becomes the selling mode and a drink extraction button 8 is depressed, a predetermined time relay 11 is energized to open a valve 10, thereby discharging a predetermined quantity of drink. After the drink is discharged, the valve 10 is opened at a predetermined period at each set time while the button 7 is being depressed to discharge a small amount of drink (bubble) at each time. Since an accurate amount of bubble is automatically discharged at a predetermined time interval merely by depressing the button 7, a regular quantity of bubble can be always simply extracted.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a beverage dispensing machine such as a beer dispenser, and more particularly to a device for extracting only foam from a beverage.

[Conventional technology]

FIG. 5 is a perspective view showing an example of the external appearance of a conventional beverage dispenser (beer dispenser). In FIG. When 2 is pulled toward the user, a valve (not shown) opens, and the beverage (beer) in the beverage tank is discharged from the outlet 3 and poured into the cup 4 by carbon dioxide pressure. Moreover, when the lever 2 is released, the beverage stops. When it is desired to pour foam into the cup, such as beer, a certain amount of liquid is first poured into the cup 4, and then only the foam is poured from above. To inject only foam, move lever 2 back and forth finely. As a result, a drink mainly consisting of foam is discharged little by little.

[Problem to be solved by the invention]

Conventionally, when you want to inject only foam, such as beer, you manually open and close the valve repeatedly as described above, but this method is not only very troublesome, but also prevents the amount of foam from being constant. However, there were many cases where there was too little foam or too much foam and the cup overflowed, giving a bad impression to customers. There is also a beverage dispensing machine that dispenses a preset amount of beverage by pressing a beverage extraction button, but this type of dispenser cannot extract only foam. Therefore, an object of the present invention is to provide a foam extraction device for a beverage dispensing machine that can easily extract a desired amount of foam.

[Means to solve the problem]

To achieve the above object, the present invention provides a beverage supply system that stores a beverage in a tank into which carbon dioxide gas is introduced, opens a valve when a beverage extraction button is pressed, and injects the beverage into a cup using carbon dioxide pressure. In the machine, press the foam extraction button,
When this button is pressed, a control means is provided which opens the valve at regular intervals for a given period of time to extract foam from the beverage.

[For use]

When you press the foam extraction button, the valve opens and closes automatically, allowing you to easily extract a fixed amount of foam.

【Example】

FIG. 1 is a control block diagram in an embodiment of this invention,
5 is a CPU that controls the entire beverage dispensing machine; 6 is its memory; 7 is a foam extraction button; 8 is a beverage extraction button; 9 is a mote changeover switch that switches the beverage dispensing machine between a vending mode and a valve opening time setting mode; 10 is a second solenoid valve for discharging the beverage, and 11 is a relay that opens and closes the valve 10. Foam extraction button 7, beverage extraction button 8
As shown in the external view of FIG. 4, the mode changeover switch 9 is provided on the front side of the beverage dispenser. The operation of the above configuration will be explained with reference to the flowchart shown in FIG. First, in step St, it is checked whether it is the sales mode or the setting mode from the switching signal of the mote changeover switch 9, and if it is the setting mode (NO in step S1), it is checked in step S6 whether or not the foam extraction button 7 has been pressed. Then step. In S7, the CPU 5 counts the number of times the button is pressed. Thereafter, by switching to the sales mode, it is determined that the setting is completed in step S8, and the valve opening time is proportional to the number of times the foam extraction button 7 is pressed (for example, 0.1 seconds for one press, 0.2 seconds for two presses). ) is stored in the memory 6 and the process returns to step S1. When the vending mode is entered in step S1, it is checked in step S2 whether the beverage extraction button 8 has been pressed, and if it has been pressed, the relay 11 is energized for a certain period of time to open the valve 10 and dispense a certain amount of beverage. After dispensing the beverage, it is checked in step S3 whether the valve opening time is set in the memory 6,
If it is set, it waits for the foam extraction button 7 to be pressed in step S4. Therefore, when the foam extraction button 7 is pressed, while the button is pressed, the valve 10 is opened at regular intervals for the time set in step S5, and a small amount of beverage (foam) is discharged each time. Figure 2 shows a time chart for opening and closing the valve during foam discharge, and when setting the valve opening time, the foam extraction button 7
In the case of FIG. 2(A) where is pressed once, the valve 10 opens at a constant period T for a time ΔT (for example, 0.1 seconds). Further, in the case of FIG. 2(B) in which the bubble extraction button 7 is pressed twice, it similarly opens in increments of 2×ΔT (for example, 0.2 seconds). As described above, according to the illustrated embodiment, an accurate amount of foam is automatically discharged at fixed time intervals simply by pressing the foam extraction button 7, so that a consistent amount of foam can be easily extracted at all times. I can do it. Further, the valve opening time each time can be optimally set depending on the type of beverage by the number of times the foam extraction button 7 is pressed in the setting mode. In the above embodiment, the valve 10 is opened at a constant cycle while the foam extraction button 7 is pressed, but once the foam extraction button 7 is pressed, the valve 10 is opened periodically for a fixed period of time and a fixed number of times. It can also be made to open.

【Effect of the invention】

According to this invention, simply by pressing the bubble extraction button, the valve is opened at regular intervals for a fixed period of time, so it is less time-consuming than manually opening and closing the valve repeatedly, and it also varies depending on the individual operator. becomes less.
