It is removably attached to the main body 1 by being inserted into a protrusion 7 formed on the main body 1 in an upright shape. An extraction port 8 (see FIG. 1) is formed at the bottom of the extractor 5, and a valve device 9 for opening and closing the extraction port 8 is provided. This valve device 9
When the extractor 5 is attached to the main body 1, it comes into contact with the bottle lid 4a placed over the bottle 4 and is in an open state. Reference numeral 1O denotes a vertical shaft type motor disposed on the main body 1 to be located on the left side of the extractor 5 in the figure, and a case mounting portion 11 is formed in the upper part of this motor 10. Reference numeral 12 denotes a crushing case that is detachably attached to the case mounting portion 11, and a crushing body 13 that is rotated by a motor 10 is provided at the inner bottom of the case. A powder filter part 14 (see FIG. 2) is provided on the right side of the crushing case 12 by forming a large number of fine holes, and this powder filter part 14 faces the upper opening of the extractor 5. There is. 15 is a hood part for guiding coffee powder from the powder filter part 14 into the extractor 5, one end of which surrounds the second part and both sides of the powder filter part 14;
The other end extends to near the center of the upper opening of the extractor 5, and is formed into a substantially arcuate shape that moves away from the crushing case 12 toward the bottom. This hood part 1
5 is integrally formed with the crushing case 12, and has a cylindrical molten metal pan 16 integrally formed on its upper surface, and a plurality of pouring holes 17 are formed in the inner region of this molten metal pan 16. There is. Reference numeral 18 denotes a lid portion that covers the outer side of the hood portion 15 in the upper surface opening of the extractor 5, and is integrally formed with the hood portion 15. A cylindrical part 19 is integrally formed on the lower surface of this lid part 18 to be inserted into the inner circumference of the upper end of the extractor 5. It is designed to be held by being sandwiched between the part 19 and the part 19. Reference numeral 21 denotes a hot water supply spout body rotatably provided above the hot water pan 1B, through which hot water generated by the aforementioned hot water generator (one heating pipe) flows from this hot water spout body 21 into the hot water pan 16. 22 is a cap detachably placed on the two sides of the crushing case.

Next, the operation of the above-mentioned configuration 11 will be explained. To extract coffee liquid, first, coffee beans and water are stored in the grinding case 12 and the water storage tank 2, respectively, and set in the state shown in FIG. 1. Then, when the motor 10 is energized, the coffee beans are ground by the grinding body 13. This results in
When the generated coffee powder reaches a particle size smaller than the fine pores of the powder filter section 14, it is transferred to the powder filter section 14 by centrifugal force.
jump out from The coffee powder that pops out has an arc shape)−
The paper falls onto the paper filter 20 inside the extractor 5 while being guided by the door section 15. In this case, the hood part 15, which functions to introduce the coffee powder produced in the grinding case 12 into the extractor 5, has an extremely simple structure and connects the grinding case 12 and the extractor 5 at a substantially maximum distance. Because of this, this hood part 1
Furthermore, the amount of coffee powder that is not collected into the extractor 5 is reduced, and the coffee powder recovery rate is increased. In addition, since the outer part of the hood part 15 of the upper surface opening of the extractor 5 is covered with the lid part 18, the wind generated in the crushing case 12 due to the rotation of the crushing body 13 flows into the extractor 5. Even if the coffee powder is blown into the coffee cup, the cover 18 prevents the coffee powder inside the extractor 5 from being blown away from the extractor 5 by this wind. After grinding all the coffee beans in this way,
When the hot water generator 11'4 is energized, the water storage tank 2
The water inside is sequentially turned into hot water and sent from the hot water supply opening body 21 to the hot water receiving part 16.
The coffee powder is discharged from the pouring hole 17 into the hood part 15 and dripped onto the coffee powder on the paper filter 20.

The dropped hot water penetrates into the coffee powder and extracts the coffee extract from the coffee powder.
The coffee liquid is dripped from the extraction port 8 into the bottle 4 and stored there.

After extracting the coffee liquid, the part that needs to be cleaned, that is, the part where coffee grounds adhere, is placed in the grinding case 12. Hood part 15. They are a lid part 18 and an extractor 5. Of these, the hood part 15 and lid part 18 for guiding the coffee powder into the extractor 5 are integrally formed, so they can be removed and washed all at once. Coffee grounds adhering to these can be easily and reliably removed. After cleaning the hood part 15, the lid part 18, and the crushing case 12 integrally formed therewith, the extractor 5 is removed from the protrusion 7 and washed with water, thereby completing the cleaning.

Note that in this embodiment, the hood part 15 is moved downward toward the crushing case 12.
Since it is formed in a substantially arc shape that separates from the filter part 1,
The coffee powder flying out from the extractor 4 is smoothly guided into the extractor 5 along the hood part 15, and the coffee powder received in the extractor 5 is collected relatively uniformly without being biased to one side.

The present invention is not limited to the above-mentioned embodiments, and various modifications may be made without departing from the scope of the invention, for example, the extractor 5 may be reliably attached to the lower surface of the lid portion 18 by an engaging means. Deformable.

[Effects of the Invention] As is clear from the above description, the present invention can provide the following effects. That is, since the hood is the only member for introducing the coffee powder produced in the grinding case into the extractor, the configuration of the path for introducing the coffee powder into the extractor can be extremely simplified. The recovery rate of coffee powder into the extractor can be increased. Furthermore, since the lid that covers the top surface of the extractor is integrally formed with the hood, the hood and lid can be removed and washed all at once, making cleaning easy. It has an excellent effect.
