At the same time, the air guide case 25 includes a ventilation opening 20a inside the exhaust space 25c.
Therefore, when the electric fan 24 is operated, an airflow that flows from the duct 21 through the inside of the air guide member 23 and the exhaust space 25c to the mixing mechanism chamber 2a is generated. The exhaust space 25c constitutes an exhaust passage.

Further, referring to FIG. 4, details of the x part of FIG. 2 which is the left direction C side of the beverage dispensing part 3 are shown.
The catchment basin 26 is attached to the partition plate 6 and the partition panel 20, has a water collection opening 26a at the top, and has a drainage receiving opening 26b on the side on the partition plate 6 and partition panel 20 side, A drain pipe 27 whose tip is refracted in an L shape is connected to the bottom of the lower direction B side. The inside of the water collecting basin 26 communicates with the inside of the drain pipe 27. The drainage receiving opening 26b is connected to an excess water drain pipe 29 that penetrates the partition plate 6 and the partition panel 20 and extends in the vertical direction along the partition plate 6 on the machine room 2b side. The surplus water drain pipe 29 periodically drains hot water and cold water stored in a hot water storage tank 30 (see FIG. 2) and a cold water tank (not shown) to prevent deterioration of water quality, or drains it for cleaning. It is a drain pipe. Therefore, the water collecting bowl 26 collects the beverage overflowing from the mixing case 12 into the duct 21 and hot water and cold water drained from the surplus water drain pipe 29 and sends them to the drain pipe 27.

  Further, a drain receiving member 28 is provided on the downward direction B side of the bent end of the drain pipe 27. The drainage receiving member 28 extends from the drainage pipe 27 over the downward direction B side of the scalloped cup stage 3 a of the beverage pouring part 3. And the drainage receiving member 28 has the drainage distribution part 28a from the drainage pipe 27 to the downward direction of the cup stage 3a, and the saucer part 28b which continues to the drainage circulation part 28a and covers the cup stage 3a from the downward direction. . Further, the drainage circulation part 28 a is opened on the upper direction A side to form a circulation part opening 28 a 1, and is located on the lower direction B side of the ventilation opening 20 a of the partition panel 20. Furthermore, the drainage receiving member 28 has a tubular drainage pipe 28c to which a valve (not shown) is attached in the tray part 28b.

  For this reason, the drainage receiving member 28 receives the water and beverage drained from the drainage pipe 27 and the beverage spilled from the gap between the slats of the cup stage 3a by the drainage circulation part 28a and the tray part 28b, respectively, 28c is discharged to the outside of the beverage dispenser 101. Further, the drainage circulation part 28a is provided so that the circulation part opening 28a1 extends to the downstream region of the airflow flowing out from the ventilation opening 20a of the partition panel 20, and the airflow from the ventilation opening 20a flows into the circulation part opening 28a1. It flows so as to come into contact with the water or beverage on the surface 28a2 in the drainage flow part 28a.

  Moreover, in the drink dispenser 101, the inside of the mixing mechanism chamber 2a is attached to the drink dispensing section 3 by attaching the casing 1 (see FIG. 1) omitted in FIG. 4 and closing the door 4 (see FIG. 1). This is a closed space that is blocked by the inside and the extraction portion cover 3b. The airflow flowing out from the vent opening 20a passes through the mixing mechanism chamber 2a and is discharged to the outside from a vent (not shown) provided on the left side surface 1c (see FIG. 1) of the housing 1 to be discharged from the beverage. 3 is blocked from flowing into it.

Next, the operation of the beverage dispenser 101 according to this embodiment will be described with reference to FIGS.
Referring to FIG. 1, a user selects a beverage in the operation unit 5 provided on the door 4 of the beverage dispenser 101 and requests the provision of the selected beverage. At this time, referring to FIG. 3, the raw material discharge motor 11b corresponding to the canister 11 including the powder raw material for producing the selected beverage is driven. The screw 11a is driven to rotate by driving the raw material discharge motor 11b, and the powder raw material in the canister 11 is discharged to the chute portion 12a of the mixing case 12.

  In parallel with this, cold water or hot water is supplied into the mixing portion 12 b of the mixing case 12. Further, the magnet motor 12d is driven, and the impeller 12c is rotationally driven by this drive. By the rotational drive of the impeller 12c, the powder raw material and cold water or hot water supplied into the mixing unit 12b are mixed and stirred to obtain a beverage. Note that the beverage overflowing from the mixing unit 12b flows into the duct 21 through the overflow opening 12e, and further flows into the water collecting bowl 26 from the duct drain pipe 21a. The beverage in the drainage basin 26 flows into the drainage distribution part 28a (see FIG. 4) of the drainage receiving member 28 (see FIG. 4) through the drain pipe 27 (see FIG. 4), and the drain pipe 28c (see FIG. 4). To the outside of the beverage dispenser 101.

  After the impeller 12c is rotationally driven for a preset time, the magnet motor 12d is stopped, and the beverage whose release from the mixing unit 12b is stopped by the rotation of the impeller 12c is discharged to the drink guide 13. . Then, referring to FIG. 2, the discharged beverage is poured out into the beverage dispensing unit 3 through the spout 13 b provided in the lower part of the drink guide 13. At this time, the user can receive the dispensed beverage by setting a cup in advance under the spout 13b.

  Returning to FIG. 3, when the user selects provision of a hot beverage, the beverage dispenser 101 operates the electric fan 24. As a result, steam generated by the hot water supplied into the mixing portion 12b of the mixing case 12 is sucked into the duct 21 through the overflow opening 12e, and further passes through the filter 22 to pass through the inside of the air guide member 23. It flows in the rear direction F and is sucked into the exhaust space 25 c of the air guide path case 25.

  When the steam passes through the filter 22, the mesh filter material 22 b 1 (see FIG. 7) first captures the powder raw material particles contained in the steam with a large particle diameter, and then the foam filter material 22 a ( As shown in FIG. 7, finer powder raw material particles are captured. Thereby, steam from which many powder raw material particles have been removed flows into the air guide member 23.

  Further, in the exhaust space 25 c, an air flow from the electric fan 24 toward the ventilation opening 20 a is generated by the rotation of the electric fan 24. For this reason, after the steam is sucked into the exhaust space 25c, it collides with the inner surface 25b1 of the side portion 25b (see FIG. 5) of the air guide case 25 and changes the flow direction by 90 degrees downward B. Furthermore, in the lower part of the exhaust space 25c, it collides with the inner surface 25d on the lower side B of the air guide case 25 and flows in the front direction E by changing the flow direction by 90 °, and passes through the ventilation opening 20a to mix. It is discharged into the chamber 2a. At this time, even if the powder raw material particles are still contained due to the collision with the inner surfaces 25b1 and 25d of the air guide case 25 when the flow direction is changed twice in the exhaust space 25c, the steam is introduced into the air guide passage. It is removed by adhering and depositing on the inner surfaces 25b1 and 25d of the case 25.

  Referring to FIG. 4, the steam discharged from the ventilation opening 20 a flows into the flow opening 28 a 1 of the drainage receiving member 28 by the action of the air guide plate 20 a 1. Further, the surface 28a2 in the drainage circulation portion 28a of the drainage receiving member 28 is wet because water or beverage flowing in from the drainage pipe 27 and the cup stage 3a is accumulated. For this reason, even if the powder raw material particles remain in the steam, the remaining powder raw material particles are sufficiently adsorbed and captured by the water or beverage when the steam comes into contact with the water or beverage on the surface 28a2. Is done. And the steam which contacted the water or drink on the surface 28a2 is discharged | emitted from the ventilation hole which is not shown in the housing | casing 1 (refer FIG. 1) to the exterior of the drink dispenser 101. FIG. Moreover, the powder raw material particle | grains capture | acquired by water or a drink are washed away by the water or drink which is newly discharged | emitted, and are discharged | emitted outside the drink dispenser 101 from the drain pipe 28c. In addition, even if the surface 28a2 in the drainage circulation portion 28a of the drainage receiving member 28 is not wet, the powder raw material particles remaining in the steam are separated from the steam and adhere to the surface 28a2 when the steam collides with the surface 28a2. Removed.

  Thereby, the steam passing through the mixing mechanism chamber 2a significantly reduces the amount of powder raw material particles contained, and reduces the contamination of the mixing mechanism chamber 2a with the powder raw material. Moreover, since the steam passing through the mixing mechanism chamber 2a is discharged outside the beverage dispenser 101 so as not to flow into the beverage dispensing unit 3, the inside of the beverage dispensing unit 3 is reduced from being contaminated with the powder material. Is done.

  Thus, the beverage dispenser 101 which concerns on embodiment provides a user with the hot drink which mixed the powder raw material and hot water (hot water) in the drink extraction part 3. FIG. The beverage dispenser 101 includes a mixing case 12 for mixing a powder raw material and hot water to produce a hot beverage, a duct-like exhaust space 25c for deriving steam in the mixing case 12, and a mixing case 12 An electric fan 24 that sucks steam and distributes it to the exhaust space 25c and a drainage distribution part 28a that distributes discharged water or beverages are provided. The steam in the exhaust space 25c is discharged toward the drainage circulation portion 28a.

  As a result, the steam is circulated through the duct-shaped exhaust space 25c and then discharged into the drainage circulation portion 28a. When water or beverage remains and gets wet in the drainage circulation part 28a for circulating the discharged water or beverage, the powder raw material particles contained in the steam are adsorbed by the remaining water or beverage and sufficiently removed. . Even if the inside of the drainage circulation part 28a is not wet, the steam collides with the surface 28a2 of the drainage circulation part 28a, whereby the powder raw material particles remaining in the steam are separated and attached to the surface 28a2. Furthermore, the powder raw material particles contained in the steam adhere to the inner surface of the air duct case 25 constituting the duct and are removed even in the process of flowing through the duct-shaped exhaust space 25c. Therefore, the powder raw material particles remaining in the steam are reduced and the steam is not directly discharged to the beverage pouring unit 3, thereby preventing the powder raw material particles from being scattered in the beverage pouring unit 3.

Further, in the beverage dispenser 101, the exhaust space 25c has a ventilation opening 20a having a wind guide plate 20a1, and the wind guide plate 20a1 allows the flow of steam discharged from the ventilation opening 20a into the drainage circulation portion 28a. Orient. The direction of the flow direction of steam can be ensured by the air guide plate 20a1.
Further, in the beverage dispenser 101, the drainage circulation part 28a is opened at the upper circulation part opening 28a1, and the steam in the exhaust space 25c is directed toward the upper circulation part opening 28a1 where the drainage circulation part 28a is opened. Discharged. This eliminates the need for a duct or the like that communicates the exhaust space 25c with the drainage circulation portion 28a, thereby reducing the number of parts and reducing the cost.

  In addition, the beverage dispenser 101 includes a housing 1 that constitutes an exterior, a mixing mechanism chamber 2a in which a canister 11, a mixing case 12, and a beverage dispensing unit 3 for storing powder raw materials are disposed, A partition plate 6 and a partition panel 20 are further provided to partition the machine room 2b disposed inside the housing 1. The exhaust space 25 c is formed by the partition panel 20 and a box-shaped air guide path case 25 attached to the partition panel 20, and the ventilation opening 20 a is an opening formed in the partition panel 20.

  As a result, the exhaust space 25c can be formed simply by attaching the air duct case 25 to the partition panel 20, and further, the powder material accumulated inside can be easily removed by removing the air duct case 25. . Further, by forming the ventilation opening 20a in the partition panel 20, steam flowing in the exhaust space 25c collides with the inner surfaces 25b1 and 25d of the box-shaped air guide case 25 and changes the flow direction in the middle. . By this collision, the powder raw material particles contained in the steam can be removed, and the discharge amount of the powder raw material particles to the outside of the vent opening 20a can be reduced.

  Further, in the beverage dispenser 101, the drainage circulation portion 28a is provided inside the mixing mechanism chamber 2a and is isolated from the beverage dispensing portion 3. Accordingly, even if there are powder raw material particles contained in the steam discharged from the vent opening 20a that are not adsorbed by the water or beverage in the drainage circulation portion 28a, the beverage dispensing portion 3 in the mixing mechanism chamber 2a Since it remains in the isolated part, not only the beverage pouring part 3 can be soiled but also the inside of the machine room 2b can be restrained, and further, the scattering of the powder raw material particles to the outside of the beverage dispenser 101 can be restrained. it can. Further, in order to remove the accumulated powder raw material particles from the beverage dispenser 101, it is only necessary to clean the inside of the drainage circulation part 28a and the mixing mechanism chamber 2a, and the maintainability is also improved.

  In addition, the beverage dispenser 101 includes a filter 22 for capturing the powder material contained in the steam between the mixing case 12 and the exhaust space 25c. As a result, the steam discharged from the vent opening 20a reduces the content of the powder raw material particles, so that the powder raw material particles remaining in the steam are sufficiently adsorbed by the water or beverage of the drainage circulation portion 28a, and the mixing mechanism Scattering into the chamber 2a is suppressed. Furthermore, since the filter 22 has a two-layer structure of the mesh filter material 22b1 and the foam filter material 22a, particles having a size suitable for each filter can be captured. Therefore, the filter 22 captures finer particles. be able to. Furthermore, the size of particles that can be captured can be controlled by changing and combining the mesh size of each filter material and the number of cells in the foam.

Further, in the beverage dispenser 101 of the embodiment, the steam discharged from the vent opening 20a is directed by the air guide plate 20a1, but the present invention is not limited to this, and the partition is formed on the mixing mechanism chamber 2a side. A duct that opens downward may be provided in the ventilation opening 20 a of the panel 20.
