Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water extraction coffee extractor for extracting coffee liquid in a drip manner by pouring water into ground coffee beans.

[0002]

[Prior art]

 Place a brewing container on the coffee server, set the brewing filter in the brewing container, pour ground coffee beans, pour in the hot water from above, and drip the coffee liquid to the coffee server below. For simple coffee brewers, various simple devices have been conventionally provided.

[0003]

[Problems to be solved by the device]

 However, pouring water into ground coffee beans and extracting the coffee liquid with water has not heretofore been performed at least in ordinary households. Therefore, a simple coffee extractor that is convenient for draining water has not been proposed so far. By extracting the coffee liquor with water, ice coffee can be easily made. As described above, the reason that coffee drip extraction with water has hardly been done at home in the past has been that the home roasters have not been popularized in homes, while the time has passed since roasting. If you buy beans, crush them and try to extract them with water, it is not possible to drip extract the coffee liquor sufficiently with water, and even if it is possible, it takes a long time for extraction. That is, if the coffee beans have been roasted for some time, it will be difficult to extract them with water. However, the present inventor has clarified that the coffee liquid can be sufficiently and effectively extracted with water if the coffee beans are roasted and then cooled to room temperature and ground.

Therefore, the present invention aims to provide a brewed coffee extractor having a simple structure capable of easily extracting coffee liquor with water in a short time with the spread of home roasters at home. .

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the water extraction coffee extractor of the present invention puts a filter on the inner wall of an extraction container, puts ground coffee beans, and pours water from the top to discharge the coffee liquid. The coffee extractor is provided with a water injection cassette that is set upside down with respect to the opening edge of the upper part of the extraction container. And a cap part that is detachably screwed together, and the cap part has a fitting flange that is detachably fitted to the opening edge of the upper portion of the extraction container, and a short tubular projection in the center of the cap part. It is characterized by forming a cylindrical protruding water injection port.

[0006]

[Action]

 According to the above characteristics of the present invention, in the extraction operation, first, the filter is set in the extraction container and the ground coffee beans are put. On the other hand, put the required water in the container part of the water injection cassette, screw the cap part and cover it. Then, the water injection cassette covered with this cap part is turned upside down, that is, the cap part is placed downward, and the fitting flange of the cap part is fitted to the opening edge of the upper part of the extraction container to set the water injection cassette. To do. As a result, the cylindrical protruding water injection port at the center of the cap portion protrudes downward and faces the inside of the extraction container. Water in the water injection cassette is poured into the extraction container from the cylindrical water injection port, and coffee liquid extraction is started. The water level in the extraction container rises as water is injected from the cylindrical protruding water injection port, and when the water level reaches the water level at which the cylindrical protruding water injection port is immersed, this prevents air from entering the cylindrical protruding water injection port. , The pressure in the water injection cassette drops, and more water cannot be poured. In other words, water is additionally poured as much as the water level drops by dripping downward from the extraction container, and the extraction is performed while the water level of the extraction container is maintained at a water level such that the cylindrical protruding water injection port is immersed. It will be broken. Therefore, the extraction state is stable, and the disadvantage that the coffee bean powder floating in the extraction container due to water injection enters the water injection cassette beyond the cylindrical protruding water injection port is prevented. Of course, when the water injection cassette is not used, it can be used as an ordinary drip extractor by pouring hot water for extraction. In the case of extraction with water, it is preferable to use coffee beans that have just been roasted, immediately cool them to room temperature, grind them, and put them in an extraction container.

【Example】

 FIG. 1 is a partial cross-sectional configuration diagram showing an embodiment of a water extraction coffee extractor according to the present invention.

In the figure, 10 is a coffee server, on which an extraction container 20 can be detachably mounted, and on top of this extraction container 20 a water injection cassette 30 can be detachably attached. It is designed to be set to. The coffee server 10 is a container for storing the extracted coffee liquid and pouring it into a coffee cup as needed. The brewing container 20 is a container for extracting coffee liquid from ground coffee beans. The brewing container 20 is formed into a container that spreads from bottom to top, and a suitable vertical ridge 21 is formed on the inner peripheral wall of the container. Further, a drop hole 22 for the extracted coffee liquid such as a drip hole or a slit is provided at the bottom of the container. In addition, a projection 23b for fitting with the extraction cassette 30 is provided on the edge 23a of the opening 23 at the top of the extraction container 20. 24 is a handle.

The water injection cassette 30 comprises a container part 31 for containing water and a cap part 32 for the container part 31, and the upper part of the container part 31 (in FIG. 1, the container part 31 is turned upside down, The bottom 31a of the container part 31 is on the top and the opening part 31b on the top is on the bottom), and a screw thread 31c with the cap part 32 is provided on the outer peripheral wall. On the other hand, the cap portion 32 is also provided with a screw thread 32c for screwing with the screw thread 31c on the inner wall of the cap portion 32 so as to be externally fitted to the opening 31b of the container 31. There is. Then, a fitting flange 32b is provided at the lower end of the side peripheral wall 32a of the cap portion 32 (the cap portion 32 is also upside down in FIG. 1), and the fitting flange 32b is the projection 23b of the extraction container 20. When the cap portion 32 is upside down, the cap portion 32 is set on the edge 23a of the opening 23 at the top of the extraction container 20 by detachably fitting.

Further, the cap portion 32 is provided with a cylindrical projecting water injection port 32f projecting in a short cylindrical shape at the center of its ceiling wall 32d. This cylindrical protruding water injection port 32f efficiently injects water from the water injection cassette 30 from one location, stabilizes the water level of the water in the extraction container 20, and from the extraction container 20 side to the water surface during extraction. It functions to prevent floating coffee grounds from entering the watering cassette 30. If the diameter of the cylindrical protruding water injection port 32f is too large, or if the protruding length of the cylindrical protruding water injection port 32f is too short, the coffee bean powder floating during the extraction will easily flow backward into the extraction cassette 30 and enter. Become. Reference numeral 32g is a packing for ensuring the water tightness of both the container portion 31 and the cap portion 32 of the water injection cassette 30 when they are screwed together.

How to use the brewed coffee extractor having the above-described configuration will be described. When extracting the coffee liquid with water, first, set a filter such as a paper filter along the inner peripheral wall of the extraction container 20 and put the ground coffee beans. In this case, it is preferable to use the beans that have just been roasted, immediately cool them to room temperature, grind them, and put them in an extraction container. On the other hand, a required amount of water is put into the container portion 31 of the water injection cassette 30, and the cap portion 32 is screwed to cover the lid. Then, the water injection cassette 30 is turned upside down, and the water injection cassette 30 is set by fitting it to the upper opening edge 23a of the extraction container 20 with the fitting flange 32b of the cap portion 32 that has become lower. As a result, the cylindrical projecting water injection port 32f at the center of the cap portion 32 projects downward and faces the inside of the extraction container 20. The water in the water injection cassette 30 is poured into the extraction container 20 through the cylindrical protruding water injection port 32f, and the extraction of coffee liquid is started. When water is injected from the cylindrical protruding water inlet 32f, the water level in the extraction container 20 rises, and when the cylindrical protruding water inlet 32f reaches the level at which it is immersed, air is injected through the cylindrical protruding water inlet 32f. Since it becomes impossible to enter the cassette 30 and the subsequent water injection causes a decrease in the pressure in the water injection cassette 30, further water is less poured. That is, while the water level of the extraction container is maintained at a level at which the cylindrical projecting water injection port is immersed, extraction is performed while water is additionally injected as much as the water level decreased by the drip. Therefore, the extraction is performed in a stable state, and it is possible to prevent inconvenience that coffee bean powder floating in the extraction container 20 due to water injection enters the water injection cassette 30 beyond the cylindrical protruding water injection port 32f. .
