Description

[Detailed Description of the Invention] The present invention relates to a coffee extractor that extracts coffee liquid by supplying hot water from a hot water supply mechanism to a hot water pourer attached to the upper part of a case containing coffee powder.

Conventionally, the coffee beans were crushed in a case and the coffee liquid was extracted by pouring hot water over the crushed coffee powder, but now a water pourer attached to the top of the case is suitable for crushing the coffee beans. In addition to forming a shape in which the center part bulges upward, a pouring hole is formed in the center and surrounding parts, and hot water is poured into the center of the pourer, and some of the hot water is poured into the center. The molten metal is allowed to drip into the case from the pouring hole in the middle, and most of the remaining portion flows down along the slope of the top surface and drips into the case from the pouring hole in the surrounding area. However, with the conventional configuration described above, the hot water poured into the center of the pourer is not necessarily evenly distributed around the surrounding area and flows down, but is often concentrated in one or multiple places. Therefore, the hot water cannot be evenly supplied to the coffee powder in the case, and the hot water permeates the coffee powder in the case unevenly, resulting in the extracted coffee liquid being thin and tasteless. There was a problem that occurred.

The present invention was developed in view of the above circumstances, and its purpose is to provide a coffee extractor that allows hot water to penetrate evenly throughout the coffee powder in the case, thereby extracting a rich and delicious coffee liquid. .

Hereinafter, an embodiment in which the present invention is applied to a coffee maker which is a coffee extractor having a mill mechanism will be described with reference to the drawings. Reference numeral 1 denotes a container body, which includes a mill mechanism 2 for crushing coffee beans, a drip mechanism 3 serving as a hot water supply mechanism for dripping hot water into the ground coffee powder to generate coffee liquid, and a drip mechanism 3 for storing the generated coffee liquid. It has 4 cups. A motor storage section 5 and a cup mounting table 6 are formed on the left and right sides of the lower half of the container 1, respectively, and a case storage chamber 7 and a water storage tank 8 are formed on the left and right sides of the upper half of the container 1, respectively. It is formed. On the other hand, reference numeral 9 denotes a heating plate of the drip mechanism 3, which is installed in close contact with the lower surface of the heated liquid 6a mounted on the cup mounting table 6, in which an electric heater such as a sheathed heater 10 and a heating pipe 11 are buried in parallel. One end of this heating pipe 11 is extended upward and connected to a water outlet (not shown) of the water storage tank 8, and the other end of the heating pipe 11 is rotated horizontally to the upper part of the case storage chamber 7 via a connecting pipe (not shown). It is connected to a hot water supply pipe 12 which is a part of a hot water supply mechanism 3 that is provided. Reference numeral 13 denotes a drive motor disposed within the motor storage section 5, and its rotating shaft 14 projects into the case storage chamber 7. Reference numeral 15 denotes a case installed in the case storage chamber 7, a filter support 17 having a large number of liquid passage holes 16 is installed at the bottom of the case, and a mesh-like filter 18 is installed on the top surface of this filter support 17. . Reference numeral 17a denotes an insertion tube formed in a cylindrical shape at the center of the filter support 17. Reference numeral 19 denotes a receiver attached to the lower part of the case 15. At the lowest part of this receiver there is provided an extraction port 20 facing above the cup 4, and in the center of the receiver 19 there is an insertion tube through which the rotating shaft 14 passes. 21 is formed in a raised manner. Reference numeral 22 denotes a cutter having a boss portion 23 in the center thereof, and the boss portion 23 of this cutter 22 is fitted and connected to the rotating shaft 14 via the insertion tube 17a. Now, reference numeral 24 denotes a water pourer having a substantially cylindrical shape with a bottom, the bottom wall of which is formed so that the central part bulges upward in an arc shape, and is detachably attached to the upper opening of the case 15. has been done. Reference numeral 25 denotes a cylindrical guide wall portion which also serves as a grip and is protruded from the upper surface of the central portion of the pourer 24. This guide wall portion 25 has a plurality of pouring ports, for example eight slits, provided at approximately equal intervals. A notch 26 having a shape is provided. The hot water supply port 12a of the hot water supply pipe 12 faces directly above the portion surrounded by the guide wall portion 25. Reference numeral 27 denotes two pouring holes located inside the guide wall portion 25 and surrounded by the guide wall portion 25, and reference numeral 28 denotes a plurality of pouring holes, for example eight, formed on the peripheral edge of the hot water pourer 24. The hot water holes are located so as to correspond to the notches 26, respectively. Note that 29 is a lid detachably attached to the upper opening of the container body 1.

Next, the operation of this embodiment will be explained. First, fill the water storage tank 8 with an amount of water equivalent to the number of people desired, store the corresponding amount of coffee beans in the case 15, attach the hot water pourer 24 to the opening on the top of the case 15, and pour the cup 4. is placed on the cup mounting table 6. Then, rotate the hot water pipe 12 to
A is located directly above the center of the hot water pourer 24.
After that, when the drive motor 13 of the mill mechanism 2 is energized to rotate the drive motor 13,
The coffee beans are crushed by the cutter 22 rotated by this. After crushing, the drive motor 13 is turned off and the sheathed heater 10 of the drip mechanism 3 is energized to generate heat, thereby preheating the cup 4 and simultaneously heating the heating pipe 11 supplied from the water storage tank 8. It heats the water inside to produce hot water. The boiling water generated as described above flows into the hot water pipe 1 due to its boiling pressure.
2 and is supplied to the inside of the guide wall portion 25 of the hot water pourer 24 from the hot water supply port 12a. Therefore, the guide wall section 2
A small amount of the hot water supplied to the inside of the guide wall 25 is temporarily stored in the guide wall 25 , and is dripped into the case 15 from the pouring hole 27 located inside the guide wall 25 . Notch 26 formed in
The pouring hole 28 is formed at the peripheral edge of the pouring device 24 so that the pouring hole 28 flows evenly around the pourer 24 as shown by arrow A.
It is dripped and supplied into the case 15 from there. The hot water thus supplied throughout the case 15 passes through the coffee powder and the filter 18 and is extracted as coffee liquid, and this extracted coffee liquid flows out from the extraction port 20 of the case 15. It is dropped into the cup 4 and stored.

The present invention is not limited to the embodiments described above and shown in the drawings, but may be modified as appropriate without departing from the spirit, such as being applicable not only to coffee makers but also to coffee extractors in general. Of course, it can be implemented.

As is clear from the embodiments described above, the present invention has a guiding wall protruding from the top surface of the pourer so as to surround the central pouring hole, and the pouring holes are arranged at approximately equal intervals on the guiding wall. Since the hot water supplied into the guide wall is provided in the guide wall and is configured to flow out evenly to the surrounding area through the hot water inlet, the hot water is evenly spread not only in the center of the pourer but also in the periphery of the case. To provide a coffee extractor in which hot water is supplied dropwise to the coffee powder in the case, and hot water is evenly distributed and permeated throughout the coffee powder in the case, thereby extracting rich and delicious coffee liquid.
