(Problems to be Solved by the Invention) In this beverage extraction device, the upper inner surface 2 of the cylinder 2 is
c is formed in a horizontal plane, and the opening / closing surface 3a of the valve 3
Since the trapezoidal shape is trapezoidal, the mixed solution A flowing down from the mixing ball 1 drops from the peripheral edge of the opening / closing surface 3a of the valve 3, and the dropped mixed solution A is placed on the filter 4 or the already stored mixed solution. It is stored in the cylinder 2 while colliding with A and scattering.

However, in the thus-scattered mixed liquid A, the one adhering above the liquid level A'of the cylinder 2 or the mixed liquid A remaining on the opening / closing surface 3a of the valve 3 remains as it is without being filtered. Therefore, when it was left as it was, it was unsanitary because it caused mold and the like.

In addition, since the stirring action of the mixed liquid A in the cylinder 2 is insufficient by simply dropping the mixed liquid A from the peripheral edge of the valve 3 as described above, the pressurized air is fed into the cylinder 2. As a result, the liquid mixture A is agitated, and then the pressurization step is performed, which requires a time for the agitation step, which causes a problem that the sales time of the coffee drink becomes long.

(Operation) According to the present invention, when the valve is opened, the mixed liquid flowing out of the mixing ball reaches the opening and closing surface of the valve through the inlet, and the inner surface of the upper part of the cylinder has a spherical shape having a spherical diameter substantially equal to the inner diameter of the cylinder. Therefore, it is transmitted to the entire inner surface of the cylinder through the gap between the opening / closing surface and the inner surface of the upper portion of the cylinder, and flows down along the inner surface on the circumferential side of the cylinder. The mixed liquid that has flowed down flows from the inner peripheral surface of the cylinder toward the center, then collides at the center and flows again toward the inner peripheral surface of the cylinder, and then toward the center again with the mixed liquid flowing down the inner peripheral surface. It flows and causes a convection phenomenon that circulates up and down.

Here, by driving the drive motor 352 of the valve drive mechanism 35 to push down the valve 34 as shown by the solid line in FIG. 3, the mixed liquid A in the mixing ball 31 passes through the communication passage 33 and the cylinder 32. Into the inflow port 323 of The mixed liquid A that has flowed into the inflow port 323 has a valve seat 324.
Flow on the opening / closing surface 343 of the valve 34 via the
43 and the upper inner surface 321 of the cylinder 32 through the gap B to reach the entire inner surface of the cylinder 32.
Flows down along the inner surface on the circumferential side (see the dashed-dotted line arrow in FIG. 3).
The mixed liquid A that has flowed down flows from the inner peripheral surface of the cylinder 32 toward the center, then collides at the center and flows toward the inner peripheral surface of the cylinder 32, and is again centered by the mixed liquid A flowing down the inner peripheral surface. And a convection phenomenon occurs in which the convection flows upward and downward (Fig. 3, one-dot chain line arrow).

Due to this convection phenomenon, the mixed liquid A supplied into the cylinder 32 is agitated and mixed, and it is not necessary to perform the agitation work again in the cylinder 32 as in the conventional case. In addition, the cylinder 32
Since the upper inner surface 321 and the opening / closing surface 343 of the valve 34 are each formed into a spherical shape, the mixed liquid A flowing from the inflow port 323 smoothly flows into the cylinder 32, and the mixed liquid A flows into the upper inner surface 321 and the opening / closing surface 343. Will never remain.

Thus, when the mixed liquid A is stored in the cylinder 32, the valve drive mechanism 35 is operated again to close the inflow port 323 by the valve 34. Then, the air supply pump 36 supplies air into the cylinder 32 to supply the air to the cylinder 32.
The inside is pressurized, the coffee liquid is forcibly extracted and filtered through the filter 37, and the coffee liquid is allowed to flow into the mixing box 40. Thereafter, sugar or the like is added to this extract and the mixture is poured into the cup 50 to sell hot coffee.

(Effect of the Invention) As described above, according to the present invention, the inner surface of the upper portion of the cylinder is formed in a spherical shape, and the opening / closing surface of the valve is formed in a spherical shape corresponding to the inner surface of the upper portion of the cylinder. When opened, the opening / closing surface of the valve and the inner surface of the upper part of the cylinder were set to face each other with a slight gap, so that the mixed liquid flowing from the mixing ball through the inflow port will not flow between the upper inner surface of the cylinder and the opening / closing surface of the valve. It flows down along the inner surface on the circumferential side of the cylinder through the gap between them, and causes a convection phenomenon in the cylinder to sufficiently stir and mix the mixed liquid. Therefore, it is not necessary to feed pressurized air into the cylinder to agitate the mixed liquid as in the conventional case, and there is an advantage that the beverage selling time is shortened. Further, since the inner surface of the upper portion of the cylinder and the opening / closing surface of the valve are formed into spherical shapes, the mixed liquid does not remain on the inner surface of the upper portion and the opening / closing surface, and molds are generated due to the adhesion of the mixed liquid as in the conventional case. It has the advantage of never.
