The present invention relates to a coffee maker having a grinding case for grinding coffee beans and an extractor for extracting coffee liquid.

Recently, in this type of coffee maker, in order to eliminate the operation of transferring the ground coffee powder separately after grinding the coffee beans, a powder filter unit for passing the ground coffee powder into a grinding case with a ground body for grinding coffee beans is provided. At the same time, an extractor for receiving coffee powder falling from the powder filter part is provided, and the boiling water from the boiling water generating mechanism passes through the above-described grinding case and flows down to the extractor through the powder filter part. It has been devised to provide a hot water from the powder filter portion to the coffee powder in the extractor in a diffused state by installing a.

However, in the above-described configuration, the hot water from the hot water generating device is supplied to the coffee powder in the extractor through the grinding case and the diffuser, so that the coffee liquid is extracted in the grinding case and the diffuser for a while after the coffee liquid is extracted. .

Therefore, in such a state, when the coffee beans are put in the grinding case again and ground, the ground coffee powder may not dry out and cling to the inner wall of the grinding case or discharge from the powder filter part toward the extractor. It becomes difficult and a problem arises that grinding | pulverization performance falls.

In addition, since the diffuser is located under the powder filter, the coffee powder dropped from the powder filter part onto the diffuser is blocked by the diffuser and does not fall directly below the diffuser in the extractor, thus distributing coffee powder in the extractor. Discomfort arises that the coffee liquid cannot be evenly extracted from the whole coffee powder in the extractor.

The present invention has been made in consideration of the above-described circumstances, and its object is to drop the next coffee beans immediately after the extraction of coffee liquid in order to drop the coffee powder produced in the grinding case into the extractor. It can be prevented, and furthermore, to provide a coffee maker capable of uniformly dropping the coffee powder in the extractor to uniformly extract the coffee liquid from the whole coffee powder.

The present invention is designed to install a cap receiving hot water from the hot water producing powder in the upper part of the grinding case and a hot water guide portion for flowing the hot water received in the cap out of the grinding case to the extractor. When the liquid is extracted, the hot water does not pass through the grinding case and at the same time removes the conventional diffuser disposed below the powder filter part.

Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 and 2.

First, in FIG. 1, "1" is a main body of a coffee maker, and a motor mounting chamber 2 is installed in the center of the main body, and a circular case mounting portion 3 is provided on the upper part of the motor mounting chamber 2. Is formed to protrude.

On the other hand, "14" is a pulverization case, and the cylinder 14a, which is integrally protruding from the bottom portion thereof, is fitted and fitted to the case mounting portion 3 so as to be attached and detached by a bayonet mechanism, for example. have.

In the center of the lower part of the grinding case 14, a pulverized body 15 is installed at the center freely for rotation, and the pulverized body 15 is installed at the center freely for rotation. It is connected to be able to hang or peel off the axis of rotation.

In the right wall of the pulverization case 14, a powder filter part 16 formed of a plurality of small holes 16a (see FIG. 2) is formed, and the powder filter part 16 is formed outward. In addition, the support plate 18 is formed at the lower end of the hood portion 17 so as to be approximately the same height as the bottom surface of the grinding case 14.

"19" is a pot-shaped extractor, which supports the projection plate 19a protruding around the outside of the upper end thereof from the left by engaging the engaging portion 18a formed on the support plate 18 from the left side. It is attached to the bottom of (18) so that it can be attached and removed.

Therefore, in this attachment state, as shown in FIG. 1, the upper surface of the extractor 19 is at approximately the same height as the lower surface of the grinding case 14.

At the bottom of the extractor 19, an extraction port 20 is formed, and a valve device 21 for opening and closing the extraction port 20 is provided.

And as shown in FIG. 1, in the state which set the extractor 19 and the bottle 13, the valve apparatus 21 will be in contact with the bottle lid 13a, and will be in the open state.

In the extractor 19, for example, a paper filter 22 is laid and used.

"23" is a container-shaped cap fitted to be fitted to the upper part of the crushing case 14, and the bottom of the cap is inclined downward to the right, and several through holes 24 are provided at the bottom of the right wall. At the same time, the hot water guide portion 25 in the shape of a tongue piece continuously connected to the through hole 24 is formed integrally.

The hot water guide portion 25 is inserted obliquely downward in the hood portion 17 from the cutout portion 26 (see FIG. 2) formed on the upper right wall of the grinding case 14 and received in the cap 23. The hot water is made to flow out of the grinding case 14 toward the extractor 19.

In addition, in FIG. 1, "27" is the lid which covers the upper part of the grinding case 14 in the main body 1. As shown in FIG.

The operation of the above-described configuration will be described.

To extract the coffee liquid, first, coffee beans and water are put into the grinding case 14 and the storage tank 5, respectively, and the apparatus is set in the state shown in FIG.

Then, when the motor 4 is energized, the pulverized body 15 is rotated so that the coffee beans in the pulverized case 14 begin to be pulverized by the pulverized body 15.

When the coffee beans are pulverized to produce small powdered coffee powder, the coffee powder has reached the inner surface of the powder filter unit 16 in the grinding case 14 under the rotational force of the grinding body 15. At this time, the coffee powder falls into the extractor 19 while preventing the coffee powder from passing through the small hole 16a of the powder filter part 16 and protruding into the hood part 17 and being scattered by the hood part 17. It is received into the paper filter 22.

In such a case, since there is no obstacle blocking the free fall of the ground coffee powder at the bottom of the powder filter unit 116, the ground coffee powder is not evenly struck on the paper filter 22 in the extractor 19 evenly. Dropped and received.

When all the coffee beans in the grinding case 14 are crushed in this way, the electric heater 8 of the boiling water generating mechanism 10 is electrically heated to generate heat, which is supplied from the reservoir tank 5 into the heating tube 9. The water is heated to become hot water.

The boiling water rises in the connecting pipe 11 due to boiling pressure and is ejected onto the cap 23 through the hot water spherical body 12, and flows to the right along the inclined bottom portion of the cap 23. It descends and flows out through the through hole 24 toward the hot water guide portion 25 and flows down the hot water guide portion 25 to be dripped onto the coffee powder in the extractor 19 at the lower end thereof.

In such a case, the hot water guide portion 25 is in the hood portion 17 and is located outside the grinding case 14 so that the hot water ejected by the cap 23 is directed out of the grinding case 14 toward the extractor 19. Since it flows down, it is possible to always maintain a dry state without wetting the inside of the grinding case 14.

In addition, since the hot water guide portion 25 is in the shape of a tongue, the hot water diffuses sideways while the hot water flows along the hot water guide portion 25 to be dispersed and dripped in the coffee powder in the extractor 19, and the coffee powder in the extractor 19 is dropped. Since it is contained so as not to lie on the paper filter 22 as described above, hot water is uniformly infiltrated into all the coffee powder, and evenly flows while extracting the coffee extract from all the coffee powder, and is filtered by the paper filter 22 to extract the spout. Through the 20, the liquid is dropped into the bottle 13 and stored.

Thus, when the coffee liquid is extracted, hot water flows out of the grinding case 14 toward the extractor 19, so that the inside of the grinding case 14 can be kept dry at all times. Even in the case where the coffee beans are put in the grinding case 14 to grind the coffee beans, the grinding is carried out in the same path as in the case described above, and the grinding performance is not lowered.

In addition, in this embodiment, since the upper surface of the extractor 19 is set to be substantially the same height as the lower surface of the grinding case 14, the height of the main body 1 can be made small.

That is, in the configuration in which the hot water passes through the grinding case and flows down to the extractor through the powder filter unit as in the prior art, the diffuser receives the hot water from the powder filter unit under the powder filter unit and flows the coffee powder in the extractor in a diffusion state Space for the installation is required between the grinding case and the extractor, the height of the body was so large.

On the other hand, in this embodiment, since the hot water guide portion 25, which also serves as a hot water diffusion function, is provided on the outer portion of the upper right side of the grinding case 14, between the grinding case 14 and the extractor 19. There is no need to provide a diffuser as in the prior art, and the height of the main body 1 can be made smaller.

3 and 4 show the second embodiment of the present invention, and only the parts different from those of the first embodiment described above will be denoted by the different reference numerals. In this second embodiment, the powder filter unit 28 will be described. It is characterized by the fact that it is made of a metallic member of the metal material and at the same time the cutout portion 29 is provided instead of the through hole in the portion corresponding to the hot water guide portion 25 among the circumferential walls of the cap 23. .

5 and 6 show a third embodiment of the present invention, and only the parts different from those of the first and second embodiments described above will be denoted by different reference numerals. It is characterized in that the guide portion 30 is installed separately from the cap 23.

That is, the hot water guide portion 30 is attached to the hood portion 17 in an inclined state lowered to the right side, and the flat portion 30a formed at the upper end portion thereof is positioned above the powder filter portion 16.

On the other hand, at the bottom right end of the cap 23, a flat protruding horseshoe portion 31 corresponding to the cutout portion 29 is formed.

Then, as shown in FIG. 5, in the state where the cap 23 is fitted to the upper surface of the grinding case 14, the cutout portion 229 is positioned in the hood portion 17, and the protruding horseshoe portion 31 protrudes. ) Is placed on the flat portion 30a of the hot water guide portion 30.

As a result, the hot water received by the cap 23 flows from the cut out portion 29 toward the hot water guide portion 30 and flows down toward the extractor 19 toward the outside of the grinding case 14.

The present invention installs a cap 23 receiving hot water from the hot water generating mechanism 10 in the above water of the grinding case 14, as clarified as described above, and grinds the hot water received in the cap 23. Since the hot water guide parts 25 and 30 are installed to flow down from the outside of the case 14 toward the extractor 19, soaking the inside of the grinding case 14 with hot water when the coffee liquid is extracted is performed. The grinding case 14 can be kept dry at all times without causing any deterioration of the grinding performance even if the coffee beans are ground again immediately after extraction. Moreover, they prevent the free fall of coffee powder, such as a conventional diffuser for boiling water. It is possible to provide a coffee maker having an excellent effect that the object can be removed to uniformly drop coffee powder into the extractor 119.
