Description

  The present invention relates to a beverage dispenser that mixes a powder raw material and hot water to produce a beverage.

  The beverage dispenser described in Patent Document 1 is used as a type of device that provides a user with a warm beverage such as tea or coffee. This beverage dispenser produces a beverage by mixing a powder raw material housed in a canister and hot water stored in a hot water storage tank in a mixing unit. The powder raw material in the canister is discharged from the raw material discharge port by being pushed out by the screw, and the discharged powder raw material is supplied into the mixing unit. In such a beverage dispenser, when the steam generated from the hot water in the mixing unit rises and wets the vicinity of the raw material discharge port, the powder raw material that has absorbed the moisture is fixed, and the subsequent discharge of the raw material is hindered. Therefore, in the beverage dispenser described in Patent Document 1, a fan motor for inhaling and discharging steam in the mixing unit is installed to prevent steam from reaching the raw material discharge port.

JP 2010-152520 A

  As in the beverage dispenser described in Patent Document 1, it is an effective method to suck the steam in the mixing unit using a fan motor, but at present, the effect is insufficient in the case described below. May be. First, when the operating time of the beverage dispenser becomes longer, the steam suction capability decreases due to the aging of the fan motor. In addition, when the beverage is frequently dispensed within a short time, the next dispensing starts before the fan motor finishes sucking steam. In these cases, since the suction by the fan motor cannot catch up and steam stays in the mixing unit, in addition to the problem that the powder raw material adheres in the vicinity of the raw material discharge port, the powder raw material adheres to the inner wall surface of the mixing unit. The problem of adhesion also arises. Furthermore, when the powder raw material has high hygroscopicity, there also arises a problem that the powder raw material absorbs moisture before the fan motor finishes sucking steam.

  The present invention has been made to solve such a problem, and reduces the amount of steam rising toward the raw material discharge port in the mixing unit. An object is to provide a beverage dispenser with reduced sticking.

  A beverage dispenser according to the present invention includes a canister that discharges a powder raw material contained therein from a raw material discharge port, and a mixing unit that generates a beverage by mixing the powder raw material discharged from the raw material discharge port with hot water. In the beverage dispenser, the mixing unit has a mixing part for mixing the powder raw material and hot water, and a guide part for connecting the mixing part to the raw material discharge port. The guide part is discharged from the raw material discharge port. A raw material passage for guiding the powdered raw material to the mixing portion and a closed space portion that is blocked from the raw material passage and opens toward the mixing portion are provided.

  Since the closed space portion that is blocked from the raw material passage and opens toward the mixing portion is provided in the guide portion of the mixing unit, at least a part of the steam generated from the hot water supplied to the mixing portion depends on the fan motor. Instead, the amount of steam rising toward the raw material discharge port is reduced. Note that the steam collected in the closed space becomes larger water droplets and adheres to the inner wall surface. However, since the closed space portion is blocked from the raw material passage, the amount of powder raw material adhering to the inner wall surface together with the water droplets is reduced. Is done. Furthermore, when the water droplets adhering to the inner wall surface of the closed space part flow down to the mixing part, the adhering powder raw material is washed away. Therefore, in the beverage dispenser, it is possible to reduce the amount of steam rising toward the raw material outlet in the mixing unit, and to reduce the adhesion and sticking of the powder raw material.

The mixing unit may have a water supply port for supplying hot water to the mixing unit, and the closed space may be formed at a site opposite to the water supply port.
The mixing unit includes a mixing case having a case main body that forms a part of the guide part and a cap that forms the remaining part of the guide part, and an isolation wall provided integrally with the cap serves as a guide. It is good also as a structure that a raw material channel | path and a closed space part are formed by partitioning a part.

  According to the beverage dispenser according to the present invention, the amount of steam rising toward the raw material discharge port in the mixing unit is reduced, thereby reducing adhesion and sticking of the powder raw material at the raw material discharge port.

In addition, an overflow outlet 23c is formed at the rear part of the mixing case 23 for discharging excess water generated when the beverage is produced and steam generated from the hot water supplied into the mixing case 23. On the lower side of the overflow outlet 23c, a steam vent duct 25 for receiving the discharged water and steam is provided. An opening 25b to which a filter 25a is attached is formed at the rear part of the steam vent duct 25, and an electric fan motor 26 is provided behind the opening 25b. When energized, the fan motor 26 forms a flow of air toward the rear side, and thereby sucks the air in the mixing case 23 through the overflow outlet 23c and the steam vent duct 25.

  The impeller 24 is a member for mixing the powder raw material and water supplied into the mixing case 23 and has a cylindrical shaft portion 24a. A disc-shaped connecting portion 24b in which a permanent magnet (not shown) is provided is integrally formed at the upper end of the shaft portion 24a. A stirring motor 27a for driving the impeller 24 and a magnet coupling 27b that is driven to rotate by the stirring motor 27a are disposed above the connecting portion 24b. The magnet coupling 27b attracts a permanent magnet (not shown) in the connecting portion 24b by a magnetic force, and when the stirring motor 27a is operated, the magnet coupling 27b and the impeller 24 are rotated together.

That is, the impeller 24 has its upper end supported by the magnet coupling 27b and its lower end supported by the convex portion 23d.

Here, the configuration of the mixing case 23 will be described in more detail.
As shown in FIG. 4, the mixing case 23 includes a case main body 31 and a cap 41 that are detachably provided. The mixing case 23 is configured by combining these members. The case main body 31 has a substantially cylindrical mixing component 32 having an upper opening, and a substantially U-shaped first guide component 33 opened to the rear side. On the other hand, the cap 41 has a lid portion 42 that closes the upper opening 32a of the mixing component 32, and a flat plate-like second guide component 43 that closes the rear opening 33a of the first guide component 33. The part 42 and the second guide constituent part 43 block the mixing constituent part 32 and the first guide constituent part 33, respectively, thereby forming the mixing part 23a and the guide part 23b (see FIG. 3).

  The mixing component 32 of the case body 31 has a first cylindrical part 32b in which an upper opening 32a is formed and a second cylinder having a smaller diameter than the first cylindrical part 32b, and a beverage discharge port 21a formed in the bottom. The cylindrical part 32c is connected via the slope forming part 32d. Further, a through hole 42 a for inserting the impeller 24 is formed in the center portion of the lid portion 42 of the cap 41, and water is supplied to the mixing case 23 at the side portion of the through hole 42 a. A water supply port 42b is formed.

  Upper wall portions 43a and 43b that are refracted forward are formed at both ends of the upper portion of the second guide constituting portion 43 of the cap 41. A flat plate-like isolation wall 43c that extends in the vertical direction and protrudes forward is formed on the front surface of the second guide component 43. The isolation wall 43c is formed in a portion on the opposite side of the water supply port 42b of the lid portion 42, and the upper end portion of the isolation wall 43c and the inner end portion of the upper wall portion 43a are connected. Furthermore, a flat partition wall 44 extending toward the inside of the case main body 31 is formed from the lower end of the second guide component 43.

  Here, as shown in FIG. 3, the isolation wall 43 c is formed so as to contact the front inner wall surface 31 a of the case body 31 when the cap 41 is attached to the case body 31 to form the mixing case 23. Moreover, the lower end part of the isolation wall 43c is terminated at the upper part of the mixing part 23a. That is, as shown in FIG. 5, the inside of the guide portion 23b of the mixing case 23 is divided into two by the isolation wall 43c and discharged from the raw material discharge port 15a through the shooter 12 (see FIG. 3). An isolation wall 43c forms a raw material passage 51 that is a space for guiding the powder raw material to the mixing portion 23a, and a closed space portion 52 that is blocked from the raw material passage 51 and opens toward the mixing portion 23a on the lower side. It has become a state. In addition, the water supply opening 42b and the closed space 52 are formed at portions opposite to each other with the central portion of the mixing portion 23a interposed therebetween.

  Further, when the hot water supplied into the mixing case 23 at the time of producing the beverage reaches the level of the hot water surface W indicated by the alternate long and short dash line in FIG. 5, the partition wall 44 has its lower end positioned directly above the hot water surface W. It is formed to do. That is, the partition wall 44 divides the inside of the mixing case 23 into a front side immediately above the upper surface of the hot water, that is, a guide part 23b side with the raw material passage 51 and a rear side with an overflow outlet 23c (see FIG. 2). doing. The case body 31 and the cap 41 are generally formed from a resin. That is, even if the cap 41 is configured to have the upper wall portions 43a and 43b, the isolation wall 43c, and the partition wall 44, it can be easily manufactured at low cost by, for example, injection molding.

  Returning to FIG. 3, one raw material discharge motor 18 is provided for each of the three canisters 11 (see FIG. 2). Similarly, one stirring motor 27 a is provided for each of the three mixing units 21. The material discharge motor 18, the fan motor 26 and the stirring motor 27 a are electrically connected to a control unit (not shown) provided on the front door 2 a (see FIG. 1) of the housing 2. The control unit controls the operation of the raw material discharge motor 18, the fan motor 26, and the stirring motor 27a according to the operation of the operation unit 3 by the user of the beverage dispenser 1, and mixes from the machine room 8 (see FIG. 2). The supply of water into the unit 21 is controlled.

  Next, operation | movement of the drink dispenser 1 which concerns on embodiment of this invention is demonstrated based on FIGS. As described above, the beverage dispenser 1 includes three sets of canisters 11 (see FIG. 2) and can dispense three different types of beverages. The operation is the same regardless of the type of beverage.

  First, the operation part 3 provided in the front door 2a shown in FIG. 1 is operated by the user of the beverage dispenser 1, and the type of beverage to be dispensed by the user is selected. When a beverage type is selected, a control unit (not shown) starts the operation of the raw material discharge motor 18 shown in FIG. When the operation of the material discharge motor 18 is started, the driving force is transmitted through the coupling 18b and the support member 17, whereby the rotation of the screw 16 is started. The powder raw material in the canister 11 is sequentially sent to the raw material discharge port 15a by the rotating screw 16, whereby the powder raw material is discharged from the raw material discharge port 15a.

  The powder raw material discharged from the raw material outlet 15a is guided to the guide path 12a of the shooter 12, and is supplied to the mixing unit 23a through the raw material passage 51 (see FIG. 5) of the mixing case 23. At the same time, the water stored in the machine room 8 (see FIG. 2) is supplied into the mixing unit 23a through a water supply pipe (not shown). Further, when the control unit (not shown) starts the operation of the stirring motor 27a, the magnet coupling 27b and the impeller 24 rotate as a unit. The powder raw material and water supplied into the mixing unit 23 a are mixed by the stirring blade 24 d of the rotating impeller 24, whereby a beverage is generated in the mixing unit 21.

  Here, while the impeller 24 is rotating, the beverage in the mixing unit 21 is pushed outward in the radial direction by the stirring blade 24d, so that the beverage being produced does not leak from the beverage discharge port 21a of the mixing unit 21. . When a predetermined time has elapsed since the start of the operation of the stirring motor 27a, a control unit (not shown) stops the operation of the stirring motor 27a, thereby stopping the rotation of the impeller 24. When the rotation of the impeller 24 is stopped, the generated beverage is discharged from the beverage discharge port 21a to the drink guide 22 (see FIG. 2). The drink guide 22 is poured out into a container (not shown) placed on the cup stage 5 from the spout 22a.

  In the beverage dispenser 1 that operates as described above, when the user selects a warm beverage, hot water is supplied from the hot water storage tank 9 (see FIG. 2) of the machine room 8 to the inside of the mixing case 23, and thus supplied. Steam is generated from the hot water. When this steam rises in the raw material passage 51 (see FIG. 5) in the guide portion 23b of the mixing case 23 and passes through the guide path 12a of the shooter 12, the powder raw material in the vicinity of the raw material discharge port 15a absorbs the moisture of the steam. As a result, the powder material is fixed and the discharge of the powder material from the material discharge port 15a is hindered.

  Therefore, in the beverage dispenser 1, the generated steam is sucked and discharged to the outside by operating the fan motor 26 as the hot water is supplied into the mixing case 23. Here, the inside of the mixing case 23 is partitioned by a partition wall 44 of the cap 41 into a front side which is the guide portion 23b side and a rear side which is the overflow discharge port 23c side. That is, the steam generated on the rear side of the partition wall 44 is blocked by the partition wall 44 and is not easily diffused to the guide portion 23 b side. Therefore, the amount of steam rising in the guide portion 23b is reduced, and the humidity in the vicinity of the raw material discharge port 15a is not easily increased. Therefore, sticking of the powder raw material in the vicinity of the raw material discharge port 15a is reduced.

  Further, since the air flow toward the rear side is generated in the mixing case 23 by operating the fan motor 26, a part of the powder raw material falling on the mixing portion 23a floats on the air flow. Then, it adheres to the inner wall surface of the mixing case 23. However, as described above, since steam is difficult to diffuse on the front side of the partition wall 44, the powder raw material adheres to a portion located on the front side of the partition wall 44 on the inner wall surface of the mixing case 23. Is reduced. On the other hand, steam is temporarily retained in a portion of the inner wall surface of the mixing case 23 located on the rear side of the partition wall 44 until it is sucked by the fan motor 26.

  Therefore, the powder raw material that floats on the rear side of the partition wall 44 absorbs moisture from the steam and becomes heavier, falls to the mixing unit 23a on the lower side, and becomes a beverage, so that adhesion to the inner wall surface is also reduced. In addition, the amount of the powder raw material that passes through the overflow outlet 23c of the mixing case 23 and reaches the filter 25a is reduced, and the filter 25a is less likely to be clogged, so that the frequency of maintenance such as cleaning can be reduced. .

  As described above, due to the suction of steam by the fan motor 26 and the partition in the mixing case 23 by the partition wall 44, the powder raw material adheres in the vicinity of the raw material discharge port 15a and the powder raw material adheres to the inner wall surface of the mixing case 23. Is reduced. However, in some cases, for example, when the suction capacity of the fan motor 26 is reduced due to deterioration over time, or when the beverage is frequently dispensed within a short period of time, the steam suction by the fan motor 26 may not be able to catch up.

  Here, as shown in FIG. 5, the guide portion 23b of the mixing case 23 is shielded from the raw material passage 51 and the raw material passage 51 for guiding the powder raw material to the mixing portion 23a by the isolation wall 43c, and the mixing portion 23a. It is separated by the closed space part 52 which opens toward. That is, since at least a part of the steam generated from the hot water in the mixing portion 23a is collected in the closed space portion 52, the amount of the steam rising in the raw material passage 51 and reaching the raw material discharge port 15a (see FIG. 3). Can be reduced without depending on the fan motor 26.

  That is, the mixing unit 21 in the beverage dispenser 1 is configured to collect steam with the closed space 52 in addition to sucking steam with the fan motor 26 (see FIG. 3). Therefore, as described above, even when the suction of steam by the fan motor 26 cannot catch up, the amount of steam rising toward the raw material discharge port 15a can be reduced.

  Further, since the isolation wall 43c is formed on the side opposite to the water supply port 42b for supplying hot water into the mixing portion 23a, the water supply port 42b is disposed on the right side in FIG. The space 52 is arranged on the left side. The hot water supplied from the water supply port 42b into the mixing portion 23a first falls downward as indicated by an arrow A1, hits the inner wall surface of the slope forming portion 32d, and then, as indicated by an arrow A2, the mixing portion 23a. It flows toward the center of the. Further, the hot water flowing in the direction indicated by the arrow A2 flows by the inertial force so as to run up in the slope forming portion 32d on the opposite side, that is, the closed space 52 side, as indicated by the arrow A3. Flows into the second cylindrical portion 32c as indicated by an arrow A4.

  As described above, the hot water supplied into the mixing unit 23a from the water supply port 42b has a flow indicated by arrows A2 and A3, that is, a flow from the right side to the left side in FIG. For this reason, the steam generated from the flowing hot water similarly flows from the right side to the left side. Furthermore, the steam generated from the hot water also causes a flow that rises in the mixing case 23. Therefore, as shown by arrows B1 to B4, the overall steam flow in the mixing case 23 is a flow from the lower right side to the upper left side in FIG. That is, the mixing unit 21 according to the present invention is configured to collect a larger amount of steam in the closed space 52 using the flow of hot water supplied into the mixing case 23, and to release the raw material. It is possible to further reduce the amount of steam reaching the outlet 15a.

  The steam collected in the closed space portion 52 becomes larger water droplets and adheres to the inner wall surface of the closed space portion 52. However, since the closed space portion 52 is blocked from the raw material passage 51, it adheres together with the water droplets. The amount of powder raw material to be reduced is also reduced. Further, the water droplets adhering to the inner wall surface of the closed space portion 52 flow down toward the mixing portion 23a. At this time, since the powder material adhering to the inner wall surface of the mixing case 23 is washed away, the inside of the mixing case 23 is sanitized. It is also possible to keep it.

  As described above, since the closed space portion 52 that is blocked from the raw material passage 51 and opens toward the mixing portion 23a is provided in the guide portion 23b of the mixing case 23, it is generated from the hot water supplied to the mixing portion 23a. At least a part of the steam is collected in the closed space portion 52, so that the amount of steam rising toward the raw material discharge port 15a is reduced. Therefore, according to the beverage dispenser 1 by this invention, it becomes possible to reduce adhesion and adhesion of the powder raw material to the raw material discharge port 15a and the inner wall surface of the mixing case 23.

  In addition, since the water supply port 42b and the closed space 52 are formed on the opposite sides of the central portion of the mixing portion 23a, the flow of hot water supplied from the water supply port 42b into the mixing portion 23a The generated steam can be collected in the closed space 52 using itself. Therefore, the amount of steam rising in the raw material passage 51 toward the raw material discharge port 15a is further reduced, and it is possible to further reduce the adhesion and sticking of the powder raw material.

  Furthermore, the mixing case 23, which is generally formed from a resin, includes a case body 31 that forms a part of the guide part 23b and a cap 41 that forms the remaining part of the guide part 23b. Since the raw material passage 51 and the closed space portion 52 are formed by partitioning with the isolation wall 43c provided integrally with the cap 41, the steam is not easily raised near the raw material discharge port at low cost. Can

  The beverage dispenser 1 according to the embodiment of the present invention has been described as having three canisters 11 and three mixing units 21, but the number of these members is not limited, and for example, the beverage dispensed It can be appropriately changed depending on the type.
