  Next, with reference to FIG. 12 and FIG. 13, the operation of the coffee extractor 1 when cooking coffee, in particular, the paper filter delivery device 4 and the waste collection after the coffee extracted in the cylinder 21 is filtered. The operation of the device 5 will be described.

  FIG. 12A shows a standby state of the coffee extractor 1. First, the filter block 27 is raised from this standby state, and the lower surface of the cylinder 21 is sealed while the paper filter P is pressed against the lower surface of the cylinder 21. Next, raw materials and hot water are supplied into the cylinder 21 from above, and coffee is extracted in the cylinder 21. Then, the extracted coffee is filtered by the paper filter P and carried out of the coffee extractor 1 through the filter block 27.

  Thereafter, as shown in FIG. 12B, the filter block 27 is lowered and the paper filter P is separated from the cylinder 21. In this case, as shown in the figure, the extracted soot G remains in the portion corresponding to the cylinder 21 of the paper filter P. Next, when the motor 61 is operated and the drive gear 63 rotates once, the paper feed drums 52 and 52 of the paper filter delivery device 4 rotate once in the clockwise direction in FIG. As a result, the paper filter P is pulled out from the paper holder 41 by a predetermined length while being sandwiched between the paper feed drums 52 and 52 and the paper sandwiching rollers 54 and 54, and is fed out toward the take-up reel 72. Further, in this case, by the operation of the motor 61, the take-up reel 72 is driven to rotate clockwise through the take-up reel drive mechanism 73. The paper filter P is taken up on the take-up reel 72.

  When the paper filter P is sent out as described above, the extraction residue G remaining on the paper filter P passes between the paper feed drum 52 and the paper clamping roller 54, as shown in FIG. 13 (a). In addition, by dropping by its own weight, it is accommodated in the extraction basket accommodating portion 85 of the waste container 71. Further, as shown in FIG. 13 (b), the extracted soot G that has not fallen by its own weight is scraped off by the scraper 83 when the paper filter P passes over the scraper 83. It falls as shown and is accommodated in the extraction basket accommodating portion 85. Therefore, most of the extracted soot G remaining on the paper filter P is accommodated in the extract soot container 85 of the waste container 71, while the used paper filter P in a state in which the extracted soot G is almost removed is used. The paper is taken up by the take-up reel 72 and accommodated in the used paper filter accommodating portion 86 of the waste container 71.

  Next, a manual setting procedure of the paper filter P in the coffee extractor 1 will be described with reference to FIGS. FIG. 14A shows a state before the roll part Pr of the paper filter P is loaded into the paper holder 41. From this state, first, the waste container 71 is pulled forward, removed from the coffee extractor 1, and the roll portion Pr of the paper filter P is loaded into the paper holder 41 from below as shown in FIG.

  Next, the paper holder 41 located at the use position is slightly lifted, and the locking portions 45, 45 are removed from the lock portions 25a, 25a on the extractor body 2 side. Thereby, the lock | rock of the paper holder 41 with respect to the extractor main body 2 is cancelled | released. Next, in this state, the paper holder 41 is slightly rotated forward with the support shaft 49b as a fulcrum, and the mounting screws 48, 48 of both arms 47, 47 are supported as fulcrums as shown in FIG. As shown in FIG. Thereafter, the front cover 23 of the cylinder holder 22 is opened, and the cylinder 21 is removed from the cylinder holder 22. Thereby, a relatively large space is secured above the filter block 27 in the cylinder holder 22.

  Next, while pulling out the paper filter P from the paper holder 41, as shown in FIG. 15A and FIG. 15B in sequence, the front end of the paper filter P is sent from the front of the cylinder holder 22 to above the filter block 27. Then, it passes through between the paper feed drum 52 and the paper sandwiching roller 54 at the rear thereof, and is hung below the extractor body 2.

  Next, after attaching the removed cylinder 21 to the cylinder holder 22, the paper holder 41 located at the retracted position is rotated upward, and the locking portions 45, 45 are connected to the lock portion 25a on the extractor body 2 side, 25a is engaged, and the paper holder 41 is locked in a use position. Thereafter, as shown in FIG. 16A, the front end portion of the paper filter P that hangs downward from the extractor main body 2 is pulled out to the front, and is engaged with both the engaging portions 94, 94 of the take-up reel 72. Then, the take-up reel 72 is rotated several times to slightly take up the paper filter P around the take-up reel 72. Then, as shown in FIG. 6B, the removed waste container 71 is attached to the outer case 6, and the take-up reel 72 is attached to the bearing groove 87 of the waste container 71, so that the take-up reel 72 The gear portion 92 is engaged with the reel drive gear 103. Thus, the setting of the paper filter P to the coffee extractor 1 is completed.

  As described above in detail, according to the present embodiment, when an unused paper filter P is manually set in the coffee extractor 1, the leading end of the paper filter P pulled out from the paper holder 41 is used as the extractor body 2. The paper filter P can be easily set in the coffee extractor 1 by a simple operation of sending from the front to the rear. Further, since the paper holder 41 is rotatable between the use position and the retracted position, when the cylinder 21 is attached to or removed from the extractor body 2, the paper holder 41 is positioned at the retracted position. Thus, the front of the extractor body 2 is opened, so that the cylinder 21 can be easily attached to and detached from the extractor body 2. Further, by positioning the paper holder 41 at the use position, the overall height of the coffee extractor 1 can be made compact, unlike the conventional case where the paper holder is arranged at the bottom of the extractor body. As described above, according to the coffee extractor 1 of the present embodiment, the overall height of the coffee extractor 1 including the paper holder 41 is configured in a compact manner while ensuring that the cylinder 21 is attached to and detached from the extractor body 2. be able to.

  Moreover, since the lower half part of the front surface of the paper holder 41 is open, an operator who performs maintenance of the coffee extractor 1 can visually recognize the roll part Pr of the paper filter P supported by the paper holder 41 from the front. Therefore, for example, the remaining amount of the paper filter P can be easily known without looking up the roll portion Pr of the paper filter P from below. Thereby, the worker can easily determine whether or not the existing paper filter P should be replaced.

  Furthermore, the paper feed drum 52 is rotationally driven by the motor 61, so that the paper filter P sandwiched between the paper sandwiching rollers 54 can be smoothly fed out. Further, since a linear portion 52b that does not clamp the paper filter P is provided at a predetermined position on the outer peripheral portion of the paper feed drum 52 with a predetermined interval between the paper feeding roller 54 and the straight line 52b during standby. Since the portion 52 b faces the paper clamping roller 54, a gap can be secured between the paper feed drum 52 and the paper clamping roller 54. Thereby, when the paper filter P is set between the paper feed drum 52 and the paper clamping roller 54, the paper filter P can be easily set by passing the paper filter P through the gap. Further, when the coffee extractor 1 is maintained, the paper filter P can be easily pulled out to the downstream side manually.

  In addition, this invention can be implemented in various aspects, without being limited to the said embodiment described. For example, in the embodiment, the case where the present invention is applied to a coffee extractor has been described, but the present invention can also be applied to a beverage extractor that extracts tea-based beverages using tea leaves as a raw material. Further, the detailed configuration of the coffee extractor 1 shown in the embodiment is merely an example, and can be appropriately changed within the scope of the gist of the present invention.
