A hot water tank 1 supplies a predetermined amount of hot water for each extraction operation, and a mixing chamber 1 mixes coffee powder raw materials and hot water. The mixing chamber 1 consists of a cylindrical portion 1B and a guide portion 1A formed above the cylindrical portion 1B, with the filtration device 2 serving as the floor surface. The mixing chamber 1 is movable in the vertical direction, and is urged downward and pressed against the filtration device 2 during beverage extraction. Guide part 1
When raw materials and hot water are supplied from A to mixing chamber 1,
The piston 14, which was waiting above the cylindrical portion 1B, begins to descend. When the piston 14 passes the joint between the guide portion 1A and the cylindrical portion 1B, the cylindrical portion 1B and the piston 14 are airtightly sealed to compress the air inside. As a result, extraction pressure can be applied to the mixed liquid of the supplied hot water and raw materials, the decoction is filtered and drawn out by the filtration device 2 , and the dregs from which the coffee components have been removed is passed through the filter 3 of the filtration device 2 . remains in When the piston 14 descends by a preset distance, it stops for a certain period of time until the extraction is completed, and then moves upward together with the mixing chamber 1 and stops at a predetermined position. By moving in synchronization with the piston 14, the mixing chamber 1 moves away from the filtration device 2 and stops, and the dregs on the surface of the filter 3 are removed by an unillustrated removal mechanism, completing one cycle.

抽出滓が侵入しない。 FIG. 1 shows the configuration of a filtration device 2 according to the present invention, which includes a filter 3, a gasket 7, and a beverage receiving part 6.
It consists of The beverage receiving part 6 has a filter storage part 5 at the upper part having a diameter substantially equal to the diameter of the cylindrical part 1B of the mixing chamber 1.
is open, and a spout 4 communicating with a filter storage section 5 is formed at the bottom. The filter 3 is made of stainless steel mesh or nylon mesh having micropores, which allows gas and liquid to pass through, but prevents solid matter from passing through. The filter 3 is fitted into a ring-shaped gasket 7 made of a highly elastic rubber material, and the assembly of the filter 3 and gasket 7 is then assembled into the filter storage section 5 of the beverage receiving section 6 as shown in FIG. Thus, a filtering device 2 is formed. At this time, the relationship between the outer diameter d 0 of the filter 3, the inner diameter d 1 and outer diameter d 2 of the gasket 7, and the inner diameter d 3 of the filter storage portion 5 is d 0 > d 1 and d 2 >
It is set to d3 . Therefore, all the fitting parts are press-fitted, and since pressure is applied to each mating surface of the filter 3, gasket 7, and beverage receiving part 6, brewed slag does not enter.

る。 Further, a protrusion 8 is formed on a part of the outer periphery of the gasket 7, and a recess 9 that fits into the protrusion 8 is provided in the beverage receiving portion 6. The dimension of the protrusion 8 in the protrusion direction is set longer than the dimension of the depression 9 in the same direction,
When fitted, the tip 10 of the protrusion 8 protrudes from the surface of the beverage receiver 6. Therefore, by manipulating the tip 10, the assembly of the filter 3 and gasket 7 can be easily separated from the beverage receiver 6 against the pressure of the respective mating surfaces. The thickness of the protrusion 8 is preferably approximately 1/2 of the thickness t of the gasket 7. That is,
As a result, the inner wall portion of the filter storage portion 5 can secure an inner wall surface without defects by t/2, and the above-mentioned d 2 > d 3 can be ensured.
The pressure generated by the dimensional relationship of can be effectively utilized.

を有効に利用できる。 Furthermore, as shown in FIGS. 3 and 4, a protrusion 8 provided on the gasket 7 and a recess 9 provided on the beverage receiving portion 6.
The relationship is A (width of gasket) > B (width of protrusion)
By setting ≒C (width of the depression), even if the thickness of the protrusion 8 is equal to the thickness t of the gasket 7, the above
The pressure generated by the dimensional relationships d 0 > d 1 and d 2 > d 3 can be effectively utilized.
