BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extraction / filtering beverage vending machine for extracting a mixed liquid of raw material powder and hot water by filtering with a filter.

[0002]

2. Description of the Related Art As an extraction / filtering beverage vending machine of this type, there is a coffee beverage vending machine having a structure for filtering and extracting a mixed liquid of coffee powder and hot water. As shown in FIG. 4, the conventional extraction / filtering beverage vending machine has a filter 1 on the lower surface.
2. An extractor 2 covered with, a raw material powder supply device 3 for supplying raw material powder (ground coffee beans) a to the extractor 2, a hot water supply device 4 for supplying hot water b to the extractor 2, and an extractor An on-off valve 5 for supplying pressurized air c to the device 2, a mixing bowl 6 for mixing the extract liquid d extracted from the extractor 2 with sugar e or milk f, and a controller 7 for controlling these. . Further, 8 is a cup, 9 is a raw material powder tank, 10 is a hot water tank, 11 is a sugar supply device for supplying sugar e in the sugar tank 12 to the mixing bowl 6 side, and 13 is a milk tank 1.
4 is a milk supply device for supplying the milk f in 4 to the mixing bowl 6 side.

The control section 7 performs the following control operation. When the purchaser presses the product selection button of the desired brand, the raw material powder a and the hot water b in an amount necessary for selling one cup of coffee beverage are put into the extractor 2 to extract the extract liquid. After doing
While keeping the inside of the extractor 2 in a closed state, pressurized air c is sent to force the extract liquid to be filtered by the filter 1. For example, this extraction operation is performed in about 16.5 seconds, and thereafter, the extraction liquid d is mixed with the sugar e and the milk f in the mixing bowl 6, and the mixture is dispensed into the cup 8 in about 6.5 seconds.

[0004]

By the way, in the above-mentioned conventional extraction / filtering type beverage vending machine, it is possible to provide a coffee beverage having a better taste by setting the extraction time longer. However, if the extraction time is increased, the time from when the purchaser presses the product selection button until the coffee beverage is dispensed into the cup 8 becomes longer by that amount, and the number of times that the product can be sold per hour is reduced. I will end up. Therefore, there has been a problem that the number of sales is reduced during a prosperous period in which products such as work breaks are frequently purchased, which leads to a decrease in profit.

The present invention solves the above-mentioned problems, and by setting a longer extraction time, a coffee beverage with a good taste can be obtained, while more beverages can be sold during the prosperous period and stored for a long time. It is an object of the present invention to provide an extraction / filtering beverage vending machine which does not sell an extracted beverage having a deteriorated taste.

[0006]

In order to solve the above problems, the present invention collects an extract liquid in an extraction / filtering beverage vending machine which extracts a mixed liquid of raw material powder and hot water by filtering with a filter. A storage container, a setting unit for setting extraction conditions and disposal conditions, and when the extraction conditions set by the setting unit are instructed, an extraction operation is instructed to store the extraction liquid in the storage container and the setting unit And a control unit for instructing the discarding work to discard the extract stored in the storage container at a predetermined location when the discarding conditions set by the above are met.

[0007]

With the above configuration, by setting an appropriate time before the prosperous start time as an extraction condition in the setting section,
The extraction work is started when the extraction conditions are met such as before the prosperity start time, and the extraction liquid is stored in the storage container. By setting the extraction time at this time to be long, it is possible to provide the extraction-filtered beverage having a good taste. Also, when the extraction-filtered beverage is sold after the start time of prosperity, the extraction liquid is stored in the storage container in advance, so that the extraction liquid can be quickly dispensed without performing the extraction operation. , More beverages can be sold during the prosperous period. Furthermore, when the disposal conditions such as the end time of prosperity are met, the extraction liquid stored in the storage container is discarded at a predetermined location, so that it is possible to prevent the sales of the extracted beverages that have been stored for a long time and have deteriorated taste,
It is possible to provide an extraction and filtration beverage that always has a good taste.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The same functions as those of the conventional one are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 1, in addition to the conventional structure, this extraction / filtering beverage vending machine has first and second storage containers 21 for storing the extraction liquid extracted from the extractor 2 while keeping it warm. , 22 and, for example, the time off during work is set as the prosperity period, 20 minutes before the prosperity period is set as the extraction start condition, and the time when the prosperity period ends is set as the disposal condition for the stored extract. A setting unit 23 for setting is provided. In addition, 21a and 22a are storage containers 2
An on-off valve provided at the lower ends of the 1, 2 and 22, 25 is an on-off valve 21
A flow path switching valve provided downstream of a and 22a, and 27 is a disposal bucket for accumulating the extraction liquid stored in the storage containers 21 and 22 as waste liquid. Further, in the setting unit 23, not only time but also information regarding holidays is set.

Here, the control unit 24 of the extraction / filtering type beverage vending machine performs the control operation of the following steps. As shown in FIG. 2, first, in step S1, the rest time as the prosperity period is read from the data set in the setting unit 23. At this time, it is also recognized that the period corresponding to the holiday rest time is not a prosperous period.

Next, in step S2, the start time of the holiday is 2
It is determined whether it is 0 minutes ago. Holiday start time 20
If the extraction start condition is met minutes ago, step S
In 3, the extractor 2 is caused to continuously perform the extraction operation, and the first and second storage containers 21 and 22 are filled with the extraction liquid and stored. At this time, for example, a total of 20 cups of the extract liquid filling both storage containers 21 and 22 is 6 minutes and 30 seconds (1 cup per 1 cup).
Extract for 9.5 seconds.

When the coffee drink is started to be purchased during the break time, the first storage container 21 does not perform the extraction operation.
The on-off valve 21a of 1 is opened and the extract is directly discharged from the first storage container 21 to the cup 8 side.

When the first storage container 21 is emptied after the coffee beverage has been purchased a predetermined number of times (for example, 10 cups) (step S4) (in this embodiment, the measured flow rate for one discharge in advance from the container is Measured, the number of purchases is detected to calculate the remaining amount in the container), the rest of the rest time is detected, and the record data of the conventional (for example, the past one week average) sales cup number is read during this remaining time. (Step S5), the number of sales cups expected to be sold during this break time (estimated sales amount) and the number of full storage cups of the second storage container 22 (for example, 10 cups) are compared in Step S6. To do.

When the rest time is long and the expected number of sold cups is larger than the full number of stored cups of the second storage container 22, the extraction operation is restarted in step S7. Also, step S
If the rest time ends before the first storage container 21 is emptied in No. 4, the first
The extraction liquid in the second storage containers 21, 22 is the waste bucket 2
7 is discarded (steps S8 and S9), and if the rest time has not ended, the process returns to step S4.

On the other hand, the number of sales cups (estimated sales amount) expected to be sold within this vacation time is
If the number of full storage cups of the second storage container 22 is less than,
As shown in FIG. 3, the extraction operation is refrained from in step S10. Then, after refraining from the extraction operation, the second storage container 2
When the number of stored cups of 2 becomes small (step S11) (for example, 5 cups), the rest of rest time is detected again (step S12), and whether the remaining rest time is larger than a certain value (for example, 10 minutes). If they are compared with each other (step S13) and the remaining rest time is longer than 10 minutes, for example, the extraction operation to the empty storage containers 21 and 22 is restarted in step S14. In addition, in step S11, when the number of stored cups of the second storage container 22 remains large and does not decrease, the first and second storage containers 2 are stored at the end of the rest time.
The extract liquids in 1 and 22 are discarded in the discard bucket 27 (steps S15 and S16), and if the rest time has not ended, the process returns to step S10.

In step S13, if the remaining rest time is less than 10 minutes, for example, the extraction operation is withheld in step S17, and the number of stored cups in the second storage container 22 is further reduced (step S18) ( For example, the expected number of sold cups during the rest time is calculated for 2 cups (step S19), and if it is expected that the cup will run short, only the shortage forecast is extracted (step S20).

On the other hand, in step S18, if the number of cups in the second storage container 22 does not decrease,
At the end of the break time, the first and second storage containers 21,
The extract in 22 is discarded in the discarding bucket 27 (steps S21 and S22), and if the rest time has not ended, the process returns to step S10.

As a result, for example, in a break time of 1 hour, conventionally, the extraction time was 16.5 seconds and the selling operation was performed in 13.5 seconds, and the maximum number of sold cups was 120 during the break time. However, due to the above-mentioned configuration, the first and second storage containers 21, 22
A total of 20 cups of extract liquid are stored in the storage containers 21 and 22.
By discharging from the cup to the cup 8 in 6.5 seconds, 180 cups of coffee beverage can be sold during the break time. Further, as described above, 20 cups of coffee beverage can be extracted in 6 minutes and 30 seconds (19.5 seconds per cup), so that sufficient extraction time can be obtained and coffee having a good taste can be obtained. Beverages can be sold. Furthermore, since the extraction is performed immediately before the break time, it is possible to prevent the accumulation for a long time, and it is also possible to improve the taste.

Furthermore, when the rest time is over, the stored extract is discarded, so that it is possible to prevent the sale of beverages such as coffee whose taste has deteriorated due to the prolonged storage period.

When a drink is purchased after a prosperous period such as the above-mentioned break time has passed, the extracted liquid is passed through one of the storage containers 21 and 22 without being stored, and the coffee beverages are added one by one as in the conventional case. Are extracted and discharged.

Here, although the case where two storage containers are used has been described in the above embodiment, three or more storage containers may be used, and in this case, a larger amount of the extraction liquid can be stored. It is also sufficient to use only one storage container to start the extraction work before the prosperity start time, or to start the extraction when the remaining amount in the storage container becomes low during the prosperity period. It is possible to obtain a brewing time, and it is possible to sell more beverages during a prosperous period such as break time.

Further, in the above embodiment, the case where the end of the prosperous period is set as the discard condition has been described. However, a time obtained by adding a predetermined time to the extraction time is set as the discard condition, and the predetermined time elapses. However, when the extract is stored, the extract may be discarded. Further, it may be configured such that a case where the temperature of the extract in the storage container is lowered due to a power failure is set as a discarding condition, and the extract is discarded at this time.

In the above embodiment, the case of hot coffee beverage was described, but when applied to iced beverages, a simple storage container may be used without heat retention. Further, in the above embodiment, the case where the remaining amount in the storage container is obtained by subtracting the conversion amount of the number of purchased cups has been described, but the remaining amount in the storage container may be directly obtained using a liquid level sensor or the like. . Furthermore, it goes without saying that it can be applied to tea as well as coffee.

[0024]

As described above, according to the present invention, the storage container for storing the extraction liquid and the setting unit for setting the extraction condition and the disposal condition are provided, and the control unit controls the extraction condition set by the setting unit. When the extraction operation is instructed, the extraction solution is stored in the storage container, and when the disposal condition is set by the setting unit, the disposal operation is instructed and the extraction solution is stored in the storage container. By disposing the extract in a predetermined place, the extraction time can be set longer and the storage time can be minimized, so that an extraction-filtered beverage with a good taste can be obtained, and the extraction liquid can be stored in the storage container. Since it stores in advance, the extraction liquid can be quickly dispensed without performing the extraction operation, more drinks can be sold during the prosperous period, and when the disposal conditions such as the end time of prosperity are met. Since the extraction liquid stored in the storage container is discarded at a predetermined place, it is possible to prevent the sales of the extracted beverage with a deteriorated taste after being stored for a long time, and it is possible to always provide the extraction-filtered beverage having a good taste. it can.
