Description

[Detailed description of the invention] The present invention relates to a rotary extraction device.

Generally, a drip type coffee extraction device is constructed by constructing a water tank 1 on a base 2 as shown in FIG. 1, and connecting one end of a pipe 4 to the bottom of the water tank 1 via a check valve 6. A heater 3 is provided in the middle of the pipe 4, and the other end is raised along the side wall of the water tank 1, and then the container 7 placed on the heater 3 is placed opposite the coffee basket 8 above. It is configured with an opening. The water flowing from the water tank 1 is heated by the heater 3 and boiled, and its expansion force causes it to rise in the pipe 4 and gradually squirt out through the opening 5 into the coffee basket 8. coffee basket 8
The extracted coffee liquid evenly penetrates into the coffee powder and naturally falls into the container 7, and continues until the water in the water tank 1 runs out. However, some of the water in water tank 1 remains contained in the coffee powder, so
There was a drawback that the amount of coffee liquid in the finished container 7 was smaller than the amount of water inside. Furthermore, there is a drawback that sufficient coffee liquid cannot be extracted unless the hot water spouted from the opening 5 of the pipe 4 is uniformly dispersed and poured over the coffee grounds in the coffee basket 8. Therefore, in order to extract the desired coffee liquid, it becomes necessary to use a large amount of coffee powder, which is uneconomical.

The present invention aims to eliminate such conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings.

FIG. 2 is a schematic external perspective view of the present invention. 10 is the main body,
50 is a rotary extractor, and 46 is a container. The rotary extractor 50 containing coffee powder and the empty container 46 are attached to the main body 10, the lid 28 of the water storage tank 14 is removed, and water is poured inside.
When the power cord 51 is connected to an AC power source and the switch 45 is turned on, hot coffee liquid is obtained in the container 46 after a predetermined time.

FIG. 3 shows the main body 10 excluding the rotary extractor 50 and container 46.
FIG. Reference numeral 10 denotes the main body of the rotary extractor, which is assembled on the upper surface of a base 11 in the shape of a flat rectangular container, and is shaped like a rectangular box with both upper and lower sides open. A water storage tank 14 is formed on the right side of the upper opening by a main body frame 12 and an upper right partition frame 13, and a drainage hole 15 is provided at the horizontal bottom to which one end of a water pipe 16 is connected. , the other end forms a substantially U-shaped space sandwiched between the upper left partition frame 19 and the main body frame 12 on the left side of the top opening in the heater 3 buried in the base 11; A notch 20 is provided at the bottom of the vertical part of the upper left partition frame 19, and a circular side wall 21 is provided upright at the horizontal bottom thereof.
A plurality of retaining grooves 29 are provided on the inside of 1. Then, a hot water conduit 23 is locked inside the lid 22 that covers the approximately U-shaped space, and the tip of the hot water conduit 23 is formed so as to face the center of the circular side wall 21, and the other end is attached to the base. It is connected to the other end of the water boiling pipe 18 in the heater 3 embedded in the heater 3 .

The lower opening of the main body 10 forms a box space sandwiched between the lower partition frame 24 and the main body frame 12, and the center of the electric motor 25 is aligned with the center of the circular side wall 21 and screwed into the space. Match. Further, a drive shaft 26 of the electric motor 25 is made to protrude into the upper opening, and a rotary coupler 27 is fixed to the tip thereof. Note that 28 is a lid of the water storage tank 14, which is fitted so as to be detachable.

FIG. 4 is a sectional view showing details of the rotary extractor 50,
0 is an outer tank of the rotary extractor 50, which has an extraction port 31 at the bottom of the cylindrical container-shaped outer tank, and further has a vertical side wall with an outer diameter inscribed in the circular side wall 21 of the coffee boiler at the bottom. 3
2, and a plurality of locking pieces 33 are integrally formed to be removably fitted to the rotary extraction device. and 3
Reference numeral 4 designates an inverted cone-shaped rotatable rotary tank, which has a shaft 35 molded at its bottom, is slid onto the center of a rotary extractor 50, is sealed with a sealing material 36, and has a rotary coupler 37 at its tip.
is fixed. Further, inside the rotating tank 34, a plurality of convex portions 37 and concave portions 38 are formed alternately in the vertical direction and are arranged over the entire circumference. A hole 39 is provided near a part of the upper part of all the recesses 38. Reference numeral 40 denotes a lid of the rotary tank 34, and a through hole 43 is provided in the center thereof, into which a protrusion 42 extending from the center of the lid 41 of the rotary extraction device 50 is inserted. Note that the protruding portion 42 of the lid body 41
A plurality of transparent windows 44 are provided.

The operation of the rotary extractor having the above configuration will be explained with reference to FIG. 5. First, the container 46 is placed on the heater 3, the filter 47 is placed in the rotary tank 34 of the rotary extractor 50, and the coffee powder is poured into the rotary extractor 50. Pour an appropriate amount and attach the lids 40 and 41. When the centered rotary extractor 50 is inscribed and fitted into the circular side wall 21 provided on the left side of the rotary extractor, the rotary extractor 50 is locked in the locking groove 29 provided on the circular side wall 21. At the same time when the piece 33 is locked, the rotary coupler 27 of the rotary extractor and the rotary coupler 37 of the rotary extractor 50;
Join. Next, when a predetermined amount of water is poured into the water storage tank 14, the water is filled through the drain hole 15 into the water conduit 16 and water heating tube 18, and when the switch 45 is turned on, the heater 3 is energized. As the temperature of the heater 3 rises, the temperature of the water filling the water boiling tube 18 in the power U heater 3 also rises, and when the boiling water pressure increases, hot water drips from the tip of the hot water conduit 23. begins to A reverse valve is provided between the water conduit pipe 16 and the drain hole 15 to prevent the high temperature hot water in the dust annular water boiling pipe 18 from flowing back into the water storage tank 14. The hot water dripping from the tip of the hot water conduit 23 passes through the protruding part 42 of the lid 41 of the rotary extractor 50, passes through the transparent windows 44 provided in plurality, and is evenly dispersed into the rotary tank 34. Drip into. Then, after sufficiently infiltrating the coffee powder, the electric motor 2
5 rotates, the rotating tank 34 also rotates, and the coffee liquid passes through the filter 47 and gradually rises along the recess 38 until it reaches the hole 3.
It scatters outward from the rotary extractor 9, forms a fruit at the bottom of the rotary extractor 50, and falls into the container 46 through the bottom extraction port 31. The above rotational extraction operation is continued until the water in the water storage tank section 14 runs out.
When the water runs out, the temperature of the heater 3 rises, and a nearby temperature rise prevention device works to cut off the power to the electric motor 25 and complete the rotational extraction work. The water guide pipe 16, the hot water boiling pipe 18, and the hot water pipe 28 are connected together to form a pipe body 52.

As described above, in the present invention, since the tank for extracting coffee, black tea, green tea, etc. is rotated, the coffee liquid is actively squeezed out by the centrifugal force, so that sufficient extraction is performed and the amount of coffee powder can be reduced. It is economical. Furthermore, since the process is forcibly performed manually, by a spring, or by an electric motor, the dripping speed of hot water can be increased, which has the advantage of shortening the extraction time. In addition, in the present invention, it is also possible to attach a so-called coffee mill equipped with a rotary extractor and a tar as separate parts and use it as a coffee extraction device with a mill.
