JPH0991535A - Liquid extracting device for beverage supply machine - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a liquid extracting device for a beverage supply machine which can prevent a beverage from running down after beverage extraction. SOLUTION: A beverage discharge opening 12 is formed in the lower-end back part of a mixing case 5 and an extraction path 14 is inserted and connected. The extraction path 14 is provided halfway with a trap part 15 which partially swells. When a prepared beverage fills the extraction path 14 at a stretch, siphon effect starts and the beverage in the mixing case 5 flows out until a stop liquid level LS where the siphon effect stops because of air entering the extraction path 14 is reached, so that the extraction ends. Then even if a residual beverage sticking on the internal wall of the mixing case 5 runs down to raise the liquid level, the liquid level difference ΔL between the liquid level LO where the drink overflows the trap part 15 and the stop liquid level LS is set larger than an increment in liquid level due to the sticking remaining liquid, so the beverage never drips by running down over the trap part 15.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid dispenser for a beverage feeder, which is adapted to prepare a beverage by stirring a powder raw material and a drinking liquid.

[0002]

2. Description of the Related Art For example, in a beverage feeder that supplies beverages such as tea and coffee, a powdered raw material such as tea and coffee is stirred and mixed with hot or cold water in a stirring container to prepare a beverage. There are things I tried to do.
As a conventional example of this type of beverage supply machine, an actual fair 5-46
There is one described in Japanese Patent Publication No. 148.

This is equipped with a stirring tool in a stirring container,
By supplying an appropriate amount of powder raw material and an appropriate amount of hot water (or cold water) into the stirring container, and rotating the stirring tool,
The hot water and the powder raw material are stirred. The beverage prepared in this manner sequentially flows out from the discharge port at the bottom of the stirring container, and is supplied from the spout to the cup of the sales port through the spout passage.

[0004]

However, in the above-mentioned conventional liquid pouring device, the residual beverage adhering to the inner wall of the stirring container flows down to the bottom of the container even after the pouring of the prepared beverage is completed, and it is the spout. There was a problem that a so-called drooling phenomenon occurred, in which the dripping occurred one after another. Therefore, an object of the present invention is to prepare a beverage by stirring a powdered raw material and a drinking liquid, and to provide a liquid pouring device of a beverage feeder that can prevent the drooling phenomenon after the beverage is poured. It is in.

[0005]

A liquid pouring device of a beverage feeder according to the present invention supplies a powder material and a beverage liquid into a stirring container to prepare a beverage, and pours the beverage from the stirring container. In the case of pouring into a cup through an outlet, a trap portion in which a part of the flow passage is locally raised is provided in the outlet passage, and the trap portion is filled with a beverage to start the siphon phenomenon. The beverage in the stirring container is caused to flow out through the pouring path, and the liquid level difference between the overflow liquid level in the trap section and the stop liquid level of the siphon phenomenon adheres to the inner wall of the stirring container and is transmitted after the beverage is poured out. The feature is that it is set to be larger than the liquid level increase due to the adhered residual beverage.

[0006]

According to the liquid dispenser of the beverage feeder according to the present invention, the prepared beverage in the stirring container is supplied to the cup or the like located below the spout through the beverage spout passage. However, at this time, the siphon phenomenon is started when the trap portion of the pouring path is filled with the beverage at once. Then, the beverage in the stirring container continues to flow out until the liquid level is lowered, air enters into the pouring path, and the siphon phenomenon ends. After that, when the residual beverage adhering to the inner wall of the agitating container flows down to the bottom of the agitating container, the liquid level rises, but the overflow liquid level of the trap part provided in the middle of the pouring path rises due to the adhering residual beverage. Because it is set larger than the minute,
It does not flow out as a drool from the spout.

As described above, the beverage dispenser of the beverage dispenser according to the present invention has an excellent effect that it is possible to prevent dripping from occurring after the completion of the beverage supply.

The raw material stirring mechanism 2 includes an impeller 10 that is a stirring tool at the bottom of a mixing case 5 that is a stirring container. As shown in FIGS. 1 and 2, the mixing case 5 is constructed by covering a front surface of a plastic case base 5a with a front cover 5b, respectively, and a front and rear ends of which a lower end portion is curved in a semicircle shape when viewed from the front. It has a thin box-like shape and has an upper surface opening communicating with the shooter 7.
Further, as shown in FIG. 2, the hot water supply pipe 4 is provided on the right side surface thereof.
The tip of is connected. With this, the tea powder raw material T from the canister 1 and the hot water from the hot water storage tank are
It is supplied into the mixing case 5.

On the other hand, on the lower rear side of the mixing case 5, there is provided a rotary drive mechanism 11 including a stirring motor, etc., and an output shaft 11a thereof extends forward to make the back wall portion of the mixing case 5 liquid-tight. Penetrates. The impeller 1
Reference numeral 0 denotes a two-blade propeller shape, which is attached to the tip end of the output shaft 11a in a horizontal axis shape. Thus, the powder raw material T supplied into the mixing case 5 and hot water are stirred and mixed by the rotation of the impeller 10, and the powder raw material T is melted to prepare a beverage (tea).

On the back surface of the lower end of the mixing case 5, a beverage outlet 12 is provided so as to project rearward, and a filter 13 is provided so as to close the inlet of the beverage outlet 12. The filter 13 has a fine mesh shape that prevents the powder raw material T that has not completely melted in the hot water from passing therethrough.

Further, the beverage discharge port 12 has a discharge path 1
4 are connected to each other, and the pouring path 14 is formed by connecting two pouring hoses 14a and 14b made of silicon resin and a pouring outlet body 14c made of stainless steel, for example.
As shown in FIG. 2, one end of the first pouring hose 14a is inserted and connected to the beverage outlet 12 of the mixing case 5, and has an inclined shape that becomes higher toward the other end. The second spout hose 14b has a smaller diameter than the first spout hose 14a, one end of which is inserted and connected to the other end of the first spout hose 14a, and the other end of which extends vertically.
c is inserted and connected. And the second pouring hose 14
In the middle of b, there is provided a trap portion 15 which is partially raised, and has a substantially L shape as a whole, and the left side portion in FIG. 2 continues to the inclination of the first pouring hose 14a. It has an inclined shape, and the right side portion has a shape extending downward. Regarding the height of the trap portion 15,
As shown in FIGS. 3 and 4, the liquid level when the beverage overflows beyond the trap portion 15 is defined as the overflow liquid level LO, and when the liquid level is lowered, air enters the pouring path 14 and the siphon phenomenon is stopped. When the liquid level is the stop liquid level LS, the liquid level difference .DELTA.L (= LO-LS) becomes larger than the liquid level increase caused by the residual beverage adhering to the inner wall of the mixing case 5 flowing down. Is set. next,
The operation of the above configuration will be described. When a beverage pouring switch (not shown) is turned on, the hot water supply valve provided in the hot water supply pipe 4 is opened for a predetermined time, and the delivery coil 8 is rotated by the drive mechanism 9 for a predetermined time. As a result, a predetermined amount of hot water and powder raw material T are supplied into the mixing case 5. At the same time, the rotary drive mechanism 11 causes the impeller 10 to rotate for a predetermined time. As a result, the hot water and the powdered raw material T are stirred to prepare tea.

The prepared tea is poured into the cup or the like from the beverage discharge port 12 on the back surface of the lower end of the mixing case 5 through the pour passage 14, and at this time, the tea is trapped in the trap portion 15 of the pour passage 14. The siphon phenomenon is started because the beverage is filled all at once. As a result, the beverage in the mixing case 5 flows out to the liquid level (liquid level LS) at which air enters the pouring path 14 and the siphon phenomenon stops,
Then, the beverage dispensing ends. In this state, a slight amount of beverage remains on the inner wall of the empty mixing case 5 (see FIG. 4). Therefore, the residual beverage gradually flows down to the bottom, and the liquid level in the mixing case 5 rises. However, in this embodiment, the stop liquid level LS of the siphon phenomenon and the liquid level LO overflowing the trap portion 15
Since the liquid level difference ΔL with the liquid level is set to be larger than the liquid level increase due to the adhered residual beverage in the mixing case 5, even if the liquid level is increased by the residual beverage after the beverage is poured out, The liquid level does not exceed the overflow liquid level LO of the trap portion 15.

Therefore, according to the present embodiment, after the beverage supply is completed, the residual beverage gets over the trap portion 15 and the spout body 1.
The effect that it is possible to surely prevent the dripping from dripping from 4c little by little is obtained. Also, on the front of the main body case, an operation panel having a beverage pouring switch, an indicator lamp, etc. is provided so that it can be opened and closed.However, the operation panel was opened and closed for inspection, etc., or the main body was impacted. In this case, the residual beverage adhering to the inner wall of the mixing case 5 may fall down the inner wall all at once and be accumulated in the mixing case 5. However, in this embodiment, the spout 14
Since the trap portion is provided in the above, it is possible to surely prevent the occurrence of back drooling in the same manner as in the above description of the operation. In addition, in the mixing case 5, there is always a tendency that the beverage that has flowed down from the inner wall remains after the pouring is finished, but this can be washed at a desired time by operating the optional washing button on the operation panel. it can. That is, when the optional washing button is turned on, the tea powder raw material T is not supplied and only a predetermined amount of hot water is supplied to the mixing case 5 from the hot water supply pipe 4. Then, this hot water mixes with the remaining beverage and is poured out to the outside through the pouring path 14 by the siphon phenomenon. As a result, since the inside of the mixing case 5 is washed with hot water, the concentration of the beverage is greatly reduced and the beverage hardly remains.

At a preset time such as the closing time of every Friday, for example, the weekly timer is turned off. Based on this, the interior of the mixing case 5 is automatically washed with hot water as in the optional washing, Almost no beverage remains.
