Description

Powder accommodating unit, connector and powder accommodating unit combination, and Dutch coffee extraction device having the same

In the present invention, the air control valve is used in the Dutch coffee brewing device to control the rate at which water falls, to make it possible to fasten with various server containers, and to prevent problems such as mold or bacteria from occurring even without cleaning and disinfection It is intended to provide a powder accommodating unit, a connector and a powder accommodating unit combination, and a Dutch coffee extracting device having the same.

In Dutch coffee, the water stored in the upper part is allowed to fall little by little into the powder container containing the coffee powder, and the coffee powder is dissolved for a long time to extract the coffee liquid. extract

Unlike regular coffee, which is extracted using hot water, Dutch coffee is coffee brewed for a long time using room temperature or cold water. Cold water is dropped drop by drop and extracted slowly over a long period of time, so it is less bitter than coffee extracted with hot water, and you can feel the mild and soft flavor.

However, since Dutch coffee is extracted with cold water for a long time without heat treatment, it is vulnerable to microorganisms or bacteria propagation, so containers used for Dutch coffee must be periodically disinfected or sterilized with boiling water.

In particular, since the passage in the cochlea (glass coil) or the drip amount control valve is fine, it is difficult to clean, and coffee grounds continuously accumulate to cause microorganisms or bacteria to propagate. Nevertheless, the existing Dutch coffee extraction device used to extract Dutch coffee has problems in that it has a complicated structure, is very difficult to clean to maintain cleanliness, and is fragile and difficult to handle. There is a need for a device and method capable of extracting Dutch coffee using clean water in a simple and convenient way with a small problem of breeding microorganisms or bacteria.

Korean Patent Registration No. 10-1824522 describes a first water supply container for storing water inside and supplying water to the lower part; a second water supply container having an accommodation space therein in which water supplied from the first water supply container is stored; a water distribution member for discharging the water supplied to the inside through a plurality of outlet holes; and a valve unit controlling a supply amount of water stored in the first water supply container, and when the valve unit is opened, the second water supply container is moved from the first water supply container by a vacuum force acting on the inside of the second water supply container. Water is introduced into the water supply container, and the water inside the second water supply container is dispersed and discharged through the plurality of water outlet holes by gravity by the amount of water flowing into the second water supply container. It provides a water supply device for coffee extraction using vacuum force.”

In Korean Patent Registration No. 10-1490306, “a water receiving unit for receiving water therein; A powder receiving unit in which coffee powder is accommodated; a liquid accommodating unit provided under the powder accommodating unit and sealedly coupled to the powder accommodating unit so that the coffee extract discharged to the outside of the powder accommodating unit can be accommodated; an elevating means for elevating at least one of the water accommodating unit, the powder accommodating unit, and the liquid accommodating unit; And one end is coupled to the water accommodating portion, and the other end is coupled to the liquid accommodating portion, and the internal pressure between the water accommodating portion and the liquid accommodating portion is kept constant to make the production time of the coffee extract constant. It provides a Dutch coffee extraction device characterized in that it comprises a; pressure holding pipe.

However, the above technology is not a technology that solves the problem of breeding microorganisms or bacteria, nor does it suggest a device capable of extracting Dutch coffee using clean water in a simple way.

Therefore, there is an urgent need to develop a Dutch coffee extraction device capable of extracting Dutch coffee using clean water in a simple way while solving the problem of microorganisms or bacterial propagation.

12 is a view of a seventh embodiment in which a separate capsule is provided inside the powder container.

12 (A) is a view of an embodiment in which the capsule 58 is provided inside the powder accommodating part 30, FIG. 12 (B) is a plan view from above, and FIG. 12 (C) is a capsule 58 It is a drawing showing a perspective view of

When water is injected into the powder container 30 from the outlet pipe 23, the injected water first flows into the inner hole 58d of the capsule 58, and the introduced water passes through the inner hole 58d. The bottom of the capsule 58 is reached. And the water reaching the lower part of the capsule moves from the center to the outside (as shown in (A) of FIG. 12, the partition 58c is not formed in the lower part of the capsule). 58c) and goes up in the upper direction. Then, the water rising in the upward direction goes beyond the top of the outer wall 58a and goes down along the outer edge of the outer wall 58a to reach the lower filter 38. Meanwhile, a gap is created between the capsule outer wall 58a and the inner surface of the coffee container 33 by the external protrusion 58b, and the water moves downward through the gap. The path along which the water moves is the direction of the arrow shown in (A) of FIG. 12.)

To this end, the height of the central portion of the capsule 58 (the portion where the inner hole 58d is located) must be higher than that of the outer wall 58a. Therefore, water can flow from the inside of the outer wall 58a beyond the upper end of the outer wall 58a to the outside of the outer wall 58a.

In addition, an external protrusion 58b is formed at a certain height on the outer wall 58a of the capsule, so that a certain space is created between the surface of the outer wall 58a and the inner surface of the powder container 30, and water moves from top to bottom in that space. do. Therefore, the water introduced into the powder accommodating portion 30 passes through the coffee powder contained in the capsule 58 evenly.

On the other hand, as shown in FIG. 12(B), the external protrusions 58b are radially formed at the edge of the outer wall 58a, and the partition 58c is formed radially from the center. The outer shape of the capsule 58 matches the inner shape of the powder accommodating portion 30 so that when the capsule 58 is pushed into the powder accommodating portion 30, it is naturally installed.

In the embodiment of FIG. 12 , the connector 20 and the powder accommodating part 30 are basically separable, and it is possible to supply the powdered coffee to the powder accommodating part. In order to maintain the aroma and taste of powdered coffee in an optimal state, the upper seal 32 is attached to the upper edge of the powder container. (At this time, the upper seal 32 may be attached to the upper end of the capsule 58.)

2. When using the inner tube 40 Connect the inner tube 40 to the connector.

3. The water outlet of the water container 12 is connected to the connector 20 in a state facing upward.

4. The second air regulator provided in the customs pipe 35 is closed so that no air passes through.

5. The water outlet of the server container 50 is connected to the lower end of the powder container 30 with the water outlet of the server container 50 facing upward.

6. The lower end of the connector 20 to which the water supply container is connected is connected to the upper end of the powder accommodating part 30.

7. The second air regulator provided in the customs pipe 35 is opened to allow air to pass therethrough.

8. Control the amount of water supplied by adjusting the first air conditioner.

* Steps 1 to 3 and steps 4 to 5 may be reversed.
