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 into a case containing coffee powder.

Conventionally, coffee extractors extract coffee liquid by supplying hot water generated by a drip mechanism serving as a hot water supply mechanism to coffee grounds housed in a case. By the way, with this type of hot water, the small amount of hot water supplied during the first hot water supply penetrates a part of the coffee powder and creates a narrow passage for hot water, so that the hot water supplied after that passes almost exclusively through that passage. As a result, only a portion of the coffee powder in the case can be extracted.
There was a problem that the extracted coffee liquid was thin and tasteless.

The present invention was made in view of the above circumstances, and its purpose is to allow hot water to penetrate the entire coffee powder in the case,
Moreover, to provide a coffee extractor which can prevent the temperature of the hot water supplied into the case from a hot water supply mechanism from decreasing once the hot water permeates the entire coffee powder, and can extract a rich and delicious coffee liquid.

An embodiment of the present invention will be described below with reference to the drawings. First, in FIG. 1, reference numeral 1 denotes a container body, on which a cup mounting stand 2 is formed in the right half of the figure, and a water storage tank 3 is formed in the left half. Reference numeral 4 denotes a drip mechanism serving as a hot water supply mechanism, which consists of an electric heater 5 provided in close contact with the lower surface of the heating plate 2a attached to the cup mounting table 2, and a heating pipe 6 attached to the lower surface of the electric heater 5. One end of this heating pipe 6 is connected to the water outlet 3a of the water storage tank 3, and the other end is extended above the cup mounting table 2 to form a hot water supply pipe 7. Reference numeral 8 denotes a check valve, which is disposed within the connecting portion between the heating pipe 6 and the water outlet 3a of the water storage tank 3. A cup 9 is placed on the heating plate 2a of the cup mounting table 2. Reference numeral 10 denotes a case, which consists of a cup-shaped filter 11 and a rectangular box-shaped lid 12 attached to the upper opening of the cup-shaped filter 11. The bottom wall portion 13 of the filter 11 has a large number of liquid passage holes 1.
4 is formed, and further an extending portion 13a is formed, and the cup 9 is placed in the upper opening of the cup 9 via the extending portion 13a. A filter 15 is installed inside the filter 11. On the other hand, in the lid 12, a hot water supply port 12a is formed on the top wall thereof, and a stepped hot water diffusion plate 16 is formed on the bottom wall, and a hot water pouring hole 17 is formed in the stepped portion. It is provided. Reference numeral 18 denotes a charging device disposed within the lid 12, which will be described below. That is, 19 is a receiver rotatably installed in the lid 12 by a pin 20, which has a cylindrical shape with a partition wall on the right side of the middle part as shown in the figure, and the center of rotation by the pin 20. is set slightly to the left of the middle part. In normal times when hot water is not stored, the receiver 19 receives and stores hot water discharged from the hot water supply port 7a of the hot water supply pipe 7 with the socket 19a facing upward as shown in FIG. Moreover, when the stored hot water reaches a predetermined amount, it rotates due to its gravity to direct the socket 19a downward and perform a hot water injection operation. Reference numeral 21 denotes a lever, which is rotatably mounted on the lid body 12 by a pin 22, and the receiving portion 21a is located in the rotation locus of the right end portion of the receiver 19, and the arm portion 21b is not shown. It is designed to be held vertically at all times by appropriate means. Reference numeral 23 denotes a holding member, such as a magnet, which is held in the left and right direction at the upper part of the lid 12 by projecting a grip 23a upward through a through hole 12b formed in the upper wall of the lid 12 and clamping the grip 23a. It is movably arranged. The magnet 23 is disposed within the rotation locus of the tip protrusion 21c of the ram 21. Reference numeral 24 denotes a magnetic material affixed to the upper surface of the right end of the upper wall of the receiver 19, and the magnet 23 is positioned in its rotation locus when moved to the left.

Next, the operation of this embodiment with the above configuration will be described with reference to FIGS. 2 to 7. When producing coffee liquid, an amount of water corresponding to the desired number of people is poured into the water storage tank 3, and a corresponding amount of coffee powder is stored in the filter 11. Thereafter, the electric heater 5 of the drip mechanism 4 is energized to generate heat, thereby preheating the cup 9 and at the same time heating the water in the heating pipe 6 supplied from the water storage tank 3 to produce hot water. generate. The hot water thus generated rises in the hot water supply pipe 7 due to its boiling pressure and is injected from the hot water supply port 7a into the socket 19a of the receiver 19 via the hot water supply port 12a of the lid body 12. It is stored in the receptor 19. after that,
When the amount of hot water stored in the receiver 19 reaches a predetermined amount, the receiver 19 rotates due to its gravity as shown by arrow A in FIG.
The pouring operation is performed by dropping the hot water upward, so that hot water flows into the filter 11 through the pouring hole 17 and permeates the entire coffee powder. At this time, due to the rotation of the receiver 19, a receiving portion 21a is formed at the right end of the receiver 19.
The colliding lever 21 temporarily rotates as shown by arrow B in FIG. 3, but then returns to rotation as shown by arrow C as the right end of the receiver 19 passes.
As described above, when the stored hot water runs out due to the first turning operation, the receptacle 19 opens its socket 19a as shown by the arrow D in FIG. 4 by setting the center of rotation with the pin 20. It is rotated back to face upward. When the receiver 19 returns to rotation, the receiver 21a collides with the right end of the receiver 19 in the opposite direction to the above, and the lever 21 is now moved as shown by arrow E in FIG. When rotated, the tip protrusion 21c presses and moves the magnet 23 in the direction shown by arrow F, and moves the magnet 23 to the operating position in conjunction with the rotational closing operation of the receiver 19. Thereafter, as shown in FIG. 5, the receptacle 19, which has been rotated back, receives and stores the hot water discharged from the hot water supply port 7a, and when the amount of hot water reaches a predetermined amount, it is again indicated by the arrow G in FIG. As shown, the heated hot water is rotated to fall onto the hot water diffusion plate 16 and permeate into the coffee powder. At this time, the magnetic material 24 attached to the receiver 19 is attracted to the magnet 23 in the operating position, so that the receiver 19 is held in the position after being inserted (the first (See Figure 6). After this, the hot water supplied from the hot water supply port 7a is directly diffused on the hot water diffusion plate 16 because the socket 19a of the receiver 19 faces downward, and enters the filter 11 through the hot water pouring hole 17. The hot water that flows in and is supplied thereafter penetrates the entire coffee powder and filters through the filter 15.
The coffee liquid passes through the liquid passage hole 14 and is extracted as coffee liquid, which falls and is stored in the cup 9. As a result, the amount of hot water supplied to the filter 11 becomes as shown in the characteristic diagram of FIG. 7, where the vertical axis represents the hot water supply amount S and the horizontal axis represents time T.
After that, when the extraction of the coffee liquid is completed, by moving the magnet 23 to the right via the grip part 23a, the attraction with the magnetic body 24 is released, and the reset state shown in FIG. 1 is achieved. becomes.

As described above, according to this embodiment, the hot water supplied from the hot water supply mechanism 4 is stored in the case 10, and each time the hot water reaches a predetermined amount, the stored hot water is transferred to the case 10.
Since the charging device 18 is provided, hot water that spreads over the entire coffee powder inside the case 10 can be supplied each time, and the hot water can permeate the entire coffee powder, unlike the conventional method. There is no need to create a narrow passageway for hot water in the coffee powder, and the hot water that is subsequently supplied penetrates throughout the coffee powder, making it possible to extract a rich and delicious coffee liquid. Moreover, especially according to this example,
The charging device 18 has a receiver 19 that stores hot water from the hot water supply mechanism 4 and rotates by gravity to perform a charging operation every time the hot water reaches a predetermined amount. It can be easily done without requiring a separate power source. Furthermore, according to this embodiment, the loading device 18 moves the magnet 23 to the active position in conjunction with the first rotational closing operation of the receiver 19, and moves the magnet 23 to the operating position in conjunction with the first rotational closing operation of the receiver 19. Since the receiver 19 is held in the charging position, once the entire coffee powder has been soaked with hot water, the hot water from the hot water supply mechanism 4 is no longer stored in the receiver 19 in predetermined amounts. Since there is no temperature drop, a relatively stable and appropriate amount of hot water is supplied into the case 10, and the coffee liquid can be extracted satisfactorily.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications without departing from the scope of the invention.

As explained above, the present invention includes a receiver that stores hot water from a hot water supply mechanism and rotates every time hot water reaches a predetermined amount and performs a charging operation of charging the hot water into a case, and Since the charging device is provided with a holding member that is moved to the working position in conjunction with the charging operation and holds the receiver in the position after the charging operation when the receiver is rotated for the second time, hot water is The hot water spreads and permeates the entire coffee powder in the case, and once the hot water has permeated the entire coffee powder, it prevents the temperature of the hot water supplied from the hot water supply mechanism into the case from dropping, making it more effective. To provide a coffee extractor which has an excellent effect of being able to extract coffee liquid with a certain amount of flavor.
