Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage mixing device provided in a beverage dispensing system of a beverage dispenser, for example.

[0002]

2. Description of the Related Art A beverage mixing apparatus of this type supplies powder raw materials such as tea, coffee, cocoa and the like and hot and cold water for dissolving them into a mixing bowl as shown in, for example, Japanese Utility Model Publication No. 59-12711. Is stirred and mixed by a stirring member to prepare a beverage, and the beverage is caused to flow out from the outlet at the bottom of the mixing ball and introduced into the cup.

A ventilation port is formed on the upper surface of the mixing ball to remove moisture from steam inside the mixing ball, and the air in the mixing ball is sucked through the ventilation port.

[0004]

However, when the powder raw material is put into the mixing ball from above, the fine powder of the powder raw material floats around and adheres to the upper part of the inner wall surface of the mixing ball. Further, when the powder raw material and hot and cold water are stirred and mixed, the powder raw material temporarily floating on the surface of the mixed liquid adheres to the upper part of the inner wall surface of the mixing ball, the stirring and mixing is completed, and the beverage in the mixing ball is discharged. After that, the powder raw material attached to the upper part of the inner wall surface of the mixing ball remains as it is.

During stirring and mixing of the powder raw material and hot and cold water, the surface of the mixed liquid is severely undulated, so that the powder raw material adheres to a position considerably higher than the normal water level of the mixed liquid. If the powder raw material thus adhered is left as it is for a long period of time, not only is it hardened and difficult to remove, but also it is putrefactive and put in a sanitary unfavorable state.

The present invention has been made by paying attention to such a point, and an object thereof is to minimize adhesion of the powder raw material to the inner wall surface of the mixing ball, and even if it adheres to the inner wall surface, An object of the present invention is to provide a beverage mixing device capable of hygienic management by preventing powder raw materials from remaining for a long period of time.

[0007]

In order to achieve such an object, the present invention provides, as a first means, a mixing ball having an outlet at the bottom and an agitating member provided so as to face the outlet. And a mixer cap provided on the upper surface of the mixing ball, and a raw material input port provided in the mixer cap, while supplying hot and cold water into the mixing ball, the powder raw material of the beverage from the raw material input port In order to prepare a beverage by stirring and mixing the powdered raw material and hot and cold water with the stirring member, a plurality of through holes are uniformly formed in the peripheral edge of the mixer cap, and mixing holes are formed from these through holes. Supply hot water into the mixing ball through the inner wall surface,
As a second means, a plurality of through holes are evenly formed in the mixer cap so as to surround the raw material charging port, and hot water is supplied into the mixing ball through these through holes. As a third means, in the mixer cap, a plurality of through holes are evenly formed on the periphery of the mixer cap, and a plurality of through holes are evenly formed so as to surround the periphery of the material charging port. Hot water is supplied into the mixing ball.

[0008]

In the first means, hot water flows from the through holes formed in the peripheral edge of the mixer cap into the mixing ball along the inner wall surface of the mixing ball at the time of preparation of the beverage, and in this state from the raw material introduction port. The powder raw material of the beverage is put into the mixing bowl.

When the powder raw material is put into the mixing ball, the fine powder of the powder raw material floats and adheres to the inner wall surface of the mixing ball. The hot and cold water flowing out from the through hole flows down to the inner wall surface. Therefore, the fine powder of the powder material adhered to the inner wall surface is washed away with this hot water.

When the hot water and the powder raw material are stirred and mixed by the rotation of the stirring member, the powder raw material temporarily floating on the surface of the mixed liquid adheres to the upper part of the inner wall surface of the mixing ball. It is washed away by hot and cold water flowing out from the through hole and flowing down along the inner wall surface of the mixing ball.

As described above, the powder raw material adhering to the inner wall surface of the mixing ball at the time of adding the powder raw material and stirring and mixing is washed away by the hot and cold water flowing out from the through hole, so that the beverage is prepared and the beverage is discharged from the outlet. The amount of the powder raw material that remains on the inner wall surface of the mixing ball and remains when it is heated is very small. Then, a very small amount of the powder raw material left on the inner wall surface of the mixing ball is washed away by the hot and cold water flowing out from the through hole and flowing down at the time of the next beverage preparation.

Further, in the second means, since the through holes are arranged so as to surround the periphery of the raw material feeding port, a tubular curtain is formed below the raw material feeding port by the water flow flowing out from these through holes. It Then, the powder raw material charged into the mixing ball from the raw material charging port falls through the inside of the cylindrical curtain.

When the powder raw material falls from the raw material charging port, the fine powder floats around and tends to adhere to the inner wall surface of the mixing ball. However, as described above, the powder charged from the raw material charging port. Since the raw material falls through the inside of the cylindrical curtain formed by the water stream, the fine powder that is going to float is caused to flow downward by the water stream, and the adhesion of the mixing ball to the inner wall surface is prevented. In the third means, the actions of the first and second means work in parallel.

When the opening area of is increased, the intake amount of air from the intake port 39 increases and the intake amount of air into the mixing ball 5 decreases.

Explaining the operation at the time of preparation of the beverage, as shown in the time chart of FIG. 3A, first, hot water in the hot water storage tank 2 or cold water in the cold water tank 3 (hereinafter referred to as hot water) is mixed in the mixing ball 5. While being supplied to the water inlet 22, the stirring member 11 is driven by the motor 20 to rotate. The ventilation fan 37 is always driven, and the air in the mixing ball 5 is sequentially discharged from the ventilation port 25 to the outside through the exhaust duct 27.

The hot water supplied to the water injection port 22 flows into the inside of the mixer cap 13, and also flows out through the through holes 14 formed in the peripheral edge of the mixer cap 13 therebelow, that is, into the mixing ball 5. Since the through holes 14 are arranged adjacent to the inner wall surface of the mixing ball 5, the hot and cold water flowing out from the through holes 14 flows down along the inner wall surface of the mixing ball 5.

The hot and cold water flowing into the mixing ball 5 flows toward the outflow port 10 at the bottom of the mixing ball 5, but the stirring member 11 is rotating above the outflow port 10, so that the hot and cold water flows into the mixing member 5. The water is splashed off by 11, so that the hot and cold water does not flow out of the outlet 10 and is sequentially stored in the mixing ball 5.

The powder raw material in the canister 4 is fed into the raw material inlet 1 with a slight time lag after the inflow of hot and cold water into the mixing ball 5 and the rotation of the stirring member 11 are started.
5 is put into the mixing ball 5. Then, the powder raw material and the hot and cold water sequentially supplied into the mixing ball 5 are agitated by the rotating operation of the agitating member 11 to be mixed,
After a certain period of time, the beverage has a uniform concentration. Then, after the preparation of the beverage, the rotation of the stirring member 11 is stopped, whereby the beverage in the mixing ball 5 flows out from the outlet 10.
It is injected into the cup 7 arranged in the cup station 6 via the guide hose 8.

When the powder raw material is put into the mixing ball 5, fine powder of the powder raw material floats and adheres to the inner wall surface of the mixing ball 5, but flows out from the through holes 14 to this inner wall surface. The generated hot and cold water is flowing down, so that the fine powder of the powder material adhered to the inner wall surface is washed away by the hot and cold water.

When the hot and cold water and the powder raw material are stirred and mixed by the rotation of the stirring member 11, the powder raw material temporarily floating on the surface of the mixed liquid adheres to the upper part of the inner wall surface of the mixing ball 5. The raw material is also washed out by the hot and cold water flowing out from the through holes 14 and flowing along the inner wall surface of the mixing ball 5.

In this way, the powder raw material adhering to the inner wall surface of the mixing ball 5 at the time of adding the powder raw material and stirring and mixing is washed away by the hot and cold water flowing out from the through holes 14 ... Therefore, the beverage is prepared, and this beverage is flowed. The amount of the powder raw material remaining after adhering to the inner wall surface of the mixing ball 5 after being discharged from the outlet 10 becomes very small. Then, a very small amount of the powder raw material remaining on the inner wall surface of the mixing ball 5 is washed away by the hot and cold water flowing out from the through holes 14 ... At the time of the next beverage preparation.

Therefore, the powder raw material does not remain attached to the inner wall surface of the mixing ball 5 for a long period of time, so that there is no inconvenience that the powder raw material is spoiled.
Hygienic management can be achieved.

As shown in FIG. 3B, the supply of hot water and the stirring operation by the stirring member 11 may be temporarily interrupted during the process. In this case, during the preparation of the beverage, a part of the mixed liquid in the mixing ball 5 flows out from the outflow port 10 due to the stop of the rotation of the stirring member 11, so that the water level of the mixed liquid remaining in the mixing ball 5 is increased. Is lowered throughout the beverage preparation operation, and therefore the position of the powder raw material adhering to the inner wall surface of the mixing ball 5 is lowered during the operation, so that the hot water flowing out from each through hole 14 makes the powder raw material better. Can be washed away.

A second embodiment is shown in FIGS. 8 and 9, and in this second embodiment, a large number of through holes 1 are formed in the bottom of the mixer cap 13 so as to surround the periphery of the raw material charging port 15.
4 are evenly formed.

In such a structure, the hot and cold water supplied from the inlet 22 into the mixer cap 13 flows out from the through holes 14 ... into the mixing ball 5, but the through holes 14 ... Since it is arranged so as to surround the circumference, the water flow that flows out forms a cylindrical curtain below the raw material inlet 15. Then, the powder raw material charged from the raw material charging port 15 into the mixing ball 5 falls through the inside of the cylindrical curtain.

When the powder raw material falls from the raw material charging port 15, the fine powder floats around and is mixed with the mixing ball 5.
Try to attach to the inner wall surface of. In particular, since the air in the mixing ball 5 is flowing toward the ventilation port 25, the fine powder floats in the direction of the arrangement side of the ventilation port 25 and tries to adhere to the inner wall surface of the mixing ball 5.

However, as described above, the raw material charging port 15
The powder raw material introduced from the above falls through the inside of the cylindrical curtain formed by the water flow, and therefore the fine powder which is about to float is caused to flow downward by the water flow, and the mixing ball 5
Is prevented from adhering to the inner wall surface. Therefore, it is possible to reduce the amount of the powder raw material that adheres to and remains on the inner wall surface of the mixing ball 5 after discharging the beverage as much as possible.

FIGS. 10 and 11 show a third embodiment. In the third embodiment, the point that the fine powder of the powder raw material floats in the direction of the arrangement side of the ventilation port 25 is particularly emphasized. A plurality of through holes 14 ... Are evenly arranged at the bottom of the mixer cap 13 and at a position where the raw material charging port 15 and the ventilation port 25 are partitioned.

In such a structure, the curtain of water flow is formed by the hot and cold water flowing out from the through holes 14 into the mixing ball 5 so as to partition the raw material charging port 15 and the ventilation port 25, and thus the ventilation port. The fine powder, which tends to float toward 25, is caused to flow downward by the water flow, and is prevented from adhering to the inner wall surface of the mixing ball 5.

In the second and third embodiments as well, similar to the structure shown in the first embodiment, a large number of through holes 14 ... Are uniformly formed in the peripheral edge of the mixer cap 13. It is also possible to configure so that the hot and cold water also flows down to the inner wall surface of the mixing ball 5.

[0043]

As described above, according to the present invention, it is possible to minimize the amount of the powder raw material adhering to the inner wall surface of the mixing ball, and to prevent the powder raw material adhering to the inner wall surface from remaining for a long time. Therefore, there is an advantage that it is possible to prevent the powder raw material from spoiling and to perform hygienic management.
