Therefore, it is possible to prevent ingredients from being extracted while simplifying cleaning of the ingredient box 51.
  • the operating unit 5115 is disposed in the dispensing unit 511, and when an operating force is applied to the operating unit 5115, it is disengaged from the locked block 5125, thereby disengaging the dispensing unit 511 from the storage unit 512 and allowing the storage unit 512 to be removed from the dispensing unit 511. Therefore, the operation of the operating unit 5115 and the operation to remove the storage unit 512 from the dispensing unit 511 must be performed with different hands and cannot be performed with one hand.
  • the storage section 512 can be detached from the dispensing section 511 by sliding it back and forth relative to the dispensing section 511, which prevents a large amount of raw material from overflowing.
  • the scraper 38 is normally positioned in a standby position behind the filter block 343 and close to the drive equipment 383 such as the scraper drive mechanism 382.
  • the scraper 38 has a vertical dimension such that the upper end portion 38b is close to the bottom opening 341a of the cylinder 341. Therefore, even if poor extraction by the extractor 30 causes the filter block 343 to descend with beverage inside, causing the beverage to splash, the beverage can be prevented from splashing onto the drive equipment 383.
  • the valve shaft (air valve shaft 412 and hot water valve shaft 422) is configured with small diameter sections 412a, 422a and large diameter sections 412b, 422b with different outer diameters
  • the valve case (air valve case 411 and hot water valve case 421) is configured by connecting a first valve case component (first air valve case component 4111, first hot water valve case component 4211) in which the inner diameter of the hollow section 4111a, 4211a is smaller than the outer diameter of the large diameter section 412b, 422b, and a second valve case component (second air valve case component 4112, second hot water valve case component 4212) in which the inner diameter of the hollow section 4112a, 4212a is larger than the outer diameter of the large diameter section 412b, 422b, so that the valve shaft can be prevented from coming out of the valve case.

  • second valve case component second air valve case component 4112, second hot water valve case component 4212
  • support ribs 417, 427 are formed on the inner surface of the second valve case component, which are capable of sliding contact with O-rings 414, 424 provided at the tip side of the valve shaft. Therefore, when the valve shaft is displaced along the axial direction of the valve case, the O-rings 414, 424 are always in sliding contact with the support ribs 417, 427, which prevents the O-rings 414, 424 from being damaged or twisted due to eccentricity or the like caused by displacement of the valve shaft, thereby extending the service life.
  • the tip portions 416, 426 of the valve shafts are umbrella-shaped, and notches 418, 428 are formed in the support ribs 417, 427 at portions spaced apart from the tip of the valve case, so that the piping resistance of the valve case caused by the formation of the support ribs 417, 427 can be reduced.
  • the opening 4311 constituting the coffee introduction port 431a in the outer member 431 is formed with a guide rib 431c that divides it into upper and lower parts.
  • a part of the O-ring 433 surrounding the inlet portion 432b slides against the guide rib 431c, and the elastic restoring force prevents the O-ring 433 from sliding against the edge of the opening 4311. This prevents damage to the O-ring 433 caused by the rotation of the inner member 432, and extends the service life.
  • the coffee inlet port 431a and the stirring air inlet port 431b of the coffee valve 43 are connected to each other, and then the air pump 72 is stopped. This prevents coffee remaining inside the coffee valve 43 from entering the stirring air line 401 when the state of communication between the coffee inlet port 431a and the coffee discharge port 432a is switched from a state of communication between the coffee inlet port 431a and the stirring air inlet port 431b.
  • the control unit 12 on the condition that a cleaning command is given, brings the extractor 30, the stirring air line 401, and the extraction air line 402 into communication and fills them with hot water, so that the stirring air line 401 and the extraction air line 402 can also be cleaned well, which was previously difficult to do.
  • the drain valve 44 is linked to the vertical movement of the filter block 343.
  • the inlet 442c of the inner component 442 is blocked by the inner surface of the outer component 441.
  • the inlet 442c of the inner component 442 faces the opening 4411 that constitutes the drain discharge port 441b.
  • the filter block 343 when performing cleaning by supplying cleaning hot water to the brewer unit 34 or the like, the filter block 343 is lowered, so that the inlet 442c of the inner component 442 faces the opening 4411 of the waste liquid discharge port 441b, and the cleaning hot water is discharged into the storage bucket 80 through the drainage path 471.
  • the filter block 343 is raised again to re-introduce hot water into the cylinder 341, and then the filter block 343 is lowered, so that the re-introduced hot water passes through the waste liquid discharge port 441b, thereby cleaning the waste liquid discharge port 441b.
  • the ingredient chute section 33 can be cleaned as follows. That is, the pinch mechanism 36 elastically deforms the lower part of the passageway component 35 to close a portion of the passageway 351, and then the first hot water supply pump 62 and the second hot water supply pump 64 are driven to supply hot water to the ingredient chute section 33 and retain it there, thereby cleaning the ingredient chute section 33.
  • the hot water used to clean the ingredient chute section 33 can then be released from the closed state of the passageway component 35 by the pinch mechanism 36, and poured into the brewer unit 34 or the like, and discharged.
  • the filter block 343 may be raised, and the first hot water supply pump 62 and the second hot water supply pump 64 may be driven to store hot water in the cylinder 341 and the passage component 35.
