In the above-mentioned scraper mechanism, the scraper reciprocates on the upper surface of the filter, and during forward movement, the scraper scrapes off the extracted residue remaining on the upper surface of the filter into a waste bag.

(c) Problems to be Solved by the Invention In the scraper mechanism for scraping off the extracted scum remaining on the top surface of the filter as disclosed in the above-mentioned publication, when scraping the extracted scum from the top surface of the filter into the scum bag during forward movement, There is a possibility that the extracted scum that remains attached to the scraper and fails to be scraped will return to the top surface of the filter during the return operation, and the new raw material powder and extracted scum will be mixed with the next time the beverage is extracted, which is a problem for the quality and hygiene of the beverage. There is a problem that undesirable defects occur.

The present invention has been made in view of the above-mentioned problems, and includes a cylindrical beverage extraction device, in which a filter is provided on one bottom half surface, an opening is provided on the other bottom half surface, and the filter is installed vertically in the center of the beverage extraction device. To provide a beverage extraction device which prevents extraction scum from remaining on the top surface of the filter during the next beverage extraction by causing a wiper means to guide the extraction scum remaining on the top surface of the filter to the opening by the rotation of the rotating shaft. be.

(d) Means for Solving the Problems The present invention has been made to solve the above problems, and the inner wall has a cylindrical shape, and the bottom part contains a mixture of raw material powder and hot water that can be dropped and sent out from the upper opening. A beverage extraction chamber, which is equipped with a filter for filtering the water, an extraction section with an extracted beverage passage formed on the bottom surface of the filter, and a discharge section equipped with an opening for discharging the extracted residue; a rotating shaft that is vertically installed, one end of which is removably connected to a drive shaft of a motor, and the other end of which is rotatably supported by a support provided in the beverage extraction chamber, and a lower surface of which is in pressure contact with the filter. is attached to the rotating shaft with both sides pressed against the inner wall, partitions the extraction section and the discharge section, and scrapes off extraction residue remaining on the upper surface of the filter into the opening by rotation of the rotating shaft. The above problem is solved by a beverage brewing device equipped with a wiper.

(E) Function According to the beverage extraction device of the present invention, the extraction residue remaining on the top surface of the filter provided in the extraction part provided at the bottom of the cylindrical beverage extraction chamber is removed from the center of the beverage extraction chamber. By rotating a wiper means attached to a rotating shaft vertically disposed in the chamber, the wiper means is guided to an opening provided in a discharge section provided at the bottom of the beverage extraction chamber, so that when the next beverage is extracted, the wiper means is attached to the upper surface of the filter. Prevents extraction residue from remaining.

(f) Embodiment To explain the present invention in detail according to the drawings, Fig. 1 is a side sectional view schematically explaining a beverage extraction device as an embodiment of the present invention, and Fig. 2 is a plan sectional view of the same device. .

The symbols and configurations of FIGS. 1 and 2 will be explained below.

(1) is a beverage extraction chamber whose inner wall has a cylindrical shape and has an extraction part (1a) and a discharge part (1b) at the bottom;
A mixture of black tea leaves and hot water (3
) is disposed in the extraction section (1a), and the discharge section (1b) is provided with an opening (6) for discharging the extracted residue (5).

The black tea as an extracted beverage filtered by the filter (4) is supplied to a beverage supply section (not shown) via the extracted beverage passageway (7) and is guided to the opening (6). The extracted dregs (5) falls into an extracted dregs extractor (not shown) via a discharge passage (8).

(9) has one end removably connected to the drive shaft (11) of the motor (10) through couplings (12a) and (12b), and the other end connected to a support disposed at the center of the bottom of the beverage extraction device. It is a rotating shaft that is rotatably supported by a bearing part (13).

(14) is a lid member, which connects the through hole (15) passing through the rotation shaft (13) and the hose (2).
16) and closes the beverage extraction chamber (1).

(17) is a wiper, which is held between a wiper fixing sheet metal (18a) and a wiper fixing sheet metal (18a) fixed to the rotating shaft (9), and whose lower surface is in pressure contact with the filter (4). Both sides of the beverage extraction chamber
1) with the screw (20) in pressure contact with the inner wall (19) of
Fixed by

(21) is a filter support member that supports the filter (4), and is removably placed in the beverage extraction chamber (1).

Incidentally, when cleaning the beverage extraction chamber (1), the coupling (12a) and the coupling (12b) are removable, and the rotating shaft (9) is also removable from the coupling (12b). , lid member <14
) can be opened.

Moreover, since the bearing part (13) also supports the rotating shaft (9) in a detachable manner, the filter (4) and the filter support member (21) can also be disassembled and cleaned.

Next, to explain the operation of the beverage brewing device as an embodiment of the present invention shown in FIGS. 1 and 2, first, the black tea leaves and hot water mixed in a mixing bowl (not shown) are
is supplied onto a filter (4) disposed in the brewing section (1a) of the beverage brewing chamber (1). The filter (4
) conducts filtration and guides the extracted black tea to the extracted beverage passage (7), the beverage extraction operation is completed, and the filter (4)
The extraction power residue 5) remains on top.

Here, the motor (10) starts driving, and the drive shaft (11)
starts rotating, and the rotating shaft (11) connected to the drive shaft (11)
9) rotates in one direction, either clockwise or counterclockwise, from the state shown in FIG.

Due to the rotation of the rotating shaft (9), the wiper (17) attached to the rotating shaft (9) guides the extracted scum (5) on the filter (4) to the opening (6).

When the wiper (17) completes the operation of discharging the extraction dregs (5), the motor (10) stops driving and returns to the state shown in FIG. 2, becoming ready for the next beverage extraction operation. .If the rotating shaft (9) stops at a position where it has rotated by an integral multiple of 172 revolutions, the extracted residue (5) will be transferred to the wiper (
17), it will not remain on the top surface of the filter (4).

The above is an explanation of the operation of the beverage brewing apparatus as an embodiment of the present invention shown in FIGS. 1 and 2.

The raw material powder is not limited to black tea, but may also be coffee, green tea, etc.

<1) Effects of the Invention According to the beverage extraction device of the present invention, conventionally, the brewed residue remaining on the top surface of the filter was scraped off by a reciprocating scraper mechanism. To eliminate the inconvenience of returning the scum to the top surface of the filter during the return movement, we have created a cylindrical shape, with an extraction part with a filter at the bottom and a discharge part with an opening, and a rotary wiper to remove the extracted scum. This can be solved by guiding the problem to the opening.
