Description

The present invention relates to a beverage dispensing device for pouring sparkling beverages such as beer.

BACKGROUND ART Beverage dispensing devices have been proposed that include a foam-making mechanism that generates beer foam and pours it into a glass in the final process of dispensing beer.

For example, the beverage dispensing device described in Patent Document 1 includes a foaming mechanism that pushes the center portion of the beverage dispensing tube with a pushing member. The position of the pushing member in the height direction is determined according to the tilting operation of the operating lever (drive member) in the front and back direction.
Accordingly, in the technique described in the same document, by elastically deforming the beverage dispensing tube according to the amount of pushing, the cross-sectional area of the tube's inner cavity is narrowed to create an orifice and generate bubbles.

WO2017/208808 Patent application 2021-080608 (unpublished)

However, in the foam making mechanism described in Patent Document 1, in order to generate foam of desired quality, it is necessary to operate the operating lever so that the tilted posture is always maintained at a predetermined position. Therefore, the cross-sectional area (shape) of the orifice is also determined depending on the degree of inclination of the operating lever. For example, if the inclination is gentle, the cross-sectional area of the orifice will be large, resulting in coarse bubbles. In other words, since the cross-sectional area (shape) of the orifice depends on the operating skill of the operator, it becomes difficult to adjust the foaming. Therefore, it becomes more difficult to adjust the foam quality and the foam quality also varies, so there is room for consideration in improving the reproducibility of the adjusted foam quality.

Moreover, Patent Document 2 proposes an electric pouring mechanism that electrically controls the pressure of a tube. However, electric dispensing mechanisms require larger driven valves than mechanical ones. Therefore, there is a problem that the area occupied by the pouring mechanism becomes large. Further, since the electric type dispensing mechanism has a greatly different operability from a conventional mechanical type beverage dispensing device, the operator may feel uncomfortable when using the electric dispensing mechanism.

Therefore, the present invention has been made with attention to such problems, and is a beverage dispensing method that has excellent manual operability, allows easy adjustment of foam quality, and has high reproducibility of the adjusted foam quality. An object of the present invention is to provide a device and a beverage server including the same.

In order to solve the above problems, a beverage dispensing device according to one aspect of the present invention opens and closes the inner lumen of a flexible tube in accordance with operations by an operator to dispense, stop and stop dispensing of a sparkling beverage. A beverage dispensing device capable of switching between foaming, the device having a dispensing position for dispensing the sparkling beverage, a foaming position for dispensing the foam of the sparkling beverage, and dispensing and foaming the sparkling beverage. a control lever that can be operated by an operator to a stop position for stopping the control, a slide piece that slides back and forth in response to the operation of the control lever, and a slide piece that slides back and forth in response to the operation of the control lever; an opening/closing piece that moves back and forth in a direction opposite to the flexible tube under the action of a cam and presses the flexible tube only by the elastic force of an urging spring to open and close the inner cavity; Due to the action of the cam accompanying the sliding movement of the slide piece according to the response, the flexible tube moves back and forth in the direction opposite to the flexible tube at a position closer to the pouring side than the opening/closing piece, thereby applying the elastic force of the biasing spring to the flexible tube. and a foaming piece that squeezes the inner cavity and creates foam by pressing with a chisel.

Furthermore, in order to solve the above problems, a beverage server according to one aspect of the present invention includes a beverage pouring device according to one aspect of the present invention.

According to the beverage dispensing device and the beverage server equipped with the same according to one aspect of the present invention, the slide piece slides in response to the operation of the operating lever by the operator, and the opening/closing piece and the foam forming part are moved by the action of the cam accompanying this. By moving the piece back and forth and pressing the flexible tube, it is possible to switch between pouring, stopping pouring, and adding foam to the sparkling beverage. Therefore, it has excellent manual operability.

The opening/closing piece and the foaming piece both advance and retreat by the action of the cam as the slide piece slides, and the flexible tube is pressed against the beverage outlet path only by the elastic force of the biasing spring, so that the operator can control the opening/closing piece and the foaming piece. The pressure is regulated only by the elastic force of the biasing spring, which is preset according to the cam profile, without depending on the operating force of the lever. Therefore, the cross-sectional area of the lumen of the flexible tube after deformation can be stabilized to be substantially constant by the pressure of the opening/closing piece and the foaming piece. Therefore, since the foam quality can be easily adjusted and the adjusted foam quality has high reproducibility, foam of stable quality can be produced.
Note that "only the elastic force of the biasing spring" means that no other operating pressure or mechanical operating pressure is actively biasing. In other words, it is natural that the earth's gravity acts on the spring members, bridge members, and other structural members, and their mass under the earth's gravity is included as "pushing force due only to spring pressure." .

As described above, according to the present invention, it is possible to provide a beverage dispensing device with excellent manual operability, easy adjustment of foam quality, and high reproducibility of the adjusted foam quality, and a beverage server equipped with the same.

The mounting position of the spout nozzle 90 is maintained with the pair of nozzle holding plates 91 being guided by the pair of holding plate guide surfaces 89.

Here, the slide pieces 40 in the tap head 20 are arranged above and opposite to the tube accommodating part 80. On the upper surface of the slide piece 40, two substantially V-shaped cam grooves 45 and 46 are provided on the rear side of the fitting groove 42 and have a predetermined cam profile. A mountain portion 44 is provided between the cam groove 45 and the cam groove 46.

The slide piece 40 has a cam groove 45 for the opening/closing piece 50 formed on the upper surface of the slide piece 40 and a cam groove 46 for the foaming piece 60. A guide slot 43 extending along the sliding direction is formed to penetrate in the vertical direction so that no interference occurs in the sliding range of the sliding piece 40.

Inside the tap head 20, an opening/closing piece 50 and a foaming piece 60 are provided in order from the rear. It is engaged so that it can move forward and backward along the slope of the surface (cam profile). As a result, the opening/closing piece 50 can be moved forward and backward by the slide piece 40 to open and close the inner cavity of the flexible tube 11, and the foaming piece 60 can be moved forward and backward by the slide piece 40 to open and close the flexible tube 11. It can be elastically deformed to a state suitable for pouring out foam.

More specifically, the opening/closing piece 50 is a generally T-shaped member when viewed from the front, and includes a pressing portion 52 and a pair of cam follower portions 53 that protrude from the upper left and right sides of the pressing portion 52 . The cam follower portion 53 constitutes a downwardly convex cam follower. The pressing part 52 of the opening/closing piece 50 is inserted into the guide slot 43 from above the slide piece 40, and the pair of cam follower parts 53 are fitted in the cam grooves 45 on the rear side.

In the attached state, the opening/closing piece 50 is always biased from the upper side to the lower side in the vertical direction by the opening/closing spring 51 which is a biasing spring. In this embodiment, the elastic force adjustment mechanism 54 that adjusts the elastic force of the opening/closing spring 51 is provided with a push screw and a nut that fixes the screwing position of the pushing screw on the upper part of the opening/closing spring 51, so that the pushing force by the opening/closing spring 51 can be adjusted. It is adjustable.

Further, the foaming piece 60 is a generally T-shaped member when viewed from the front, and includes a pressing portion 62 and a pair of cam follower portions 63 that protrude from the upper left and right sides of the pressing portion 62 . The cam follower portion 63 constitutes a downwardly convex cam follower.

The bottom wall portion 86d and the pair of limiting side walls 62a, 62b contact the outer circumferential surface of the flexible tube 11 at three points simultaneously. Note that in order to provide the three-point clamping structure, a convex portion may be provided on the lower surface of the bottom wall portion 86d. However, when a convex portion is provided on the lower surface of the bottom wall portion 86d, the stability of bubble generation tends to decrease. Therefore, in the beverage dispensing device 100 of this embodiment, the lower surface of the bottom wall portion 86d is made flat.

[Operations and effects]
Next, the operation and effects of the beverage server 1 of this embodiment and the beverage dispensing device 100 equipped therein will be described. First, the maintenance of the beverage dispensing device 100, particularly the procedure for installing the beverage outlet path 10, will be explained.

During maintenance of the beverage dispensing device 100 of this embodiment, the engagement of the engagement claw 24 between the tap base 30 and the tap head 20 is released, and the tap head 20 is manually rotated upward and forward about the pivot support 34. to open position. As a result, as shown in FIG. 3(b), the space between the tap base 30 and the tap head 20 is divided, and the tube accommodating portion 80 holding the flexible tube 11 inside the beverage dispensing device 100 is separated. Open for viewing.

Next, as shown in FIG. 3(c), the beverage outlet path 10 is placed in the tube accommodating portion 80, and the tip of the flexible tube 11 is manually inserted into the pouring nozzle 90. Since tube holding parts 81 are formed as clamping parts on the left and right sides of the tube accommodating part 80, the flexible tube 11 inserted into the tube accommodating part 80 is held by the tube holding parts 81 from the left and right sides. The bent state is maintained along the tube guide surface 89 and guided to the base end of the spout nozzle 90.

Thereafter, as shown in FIG. 3(a), the tap head 20 is manually rotated to the closed position so as to overlap the tap base 30. As a result, the beverage containing the flexible tube 11 can be drawn out by passing the flexible tube 11 through a predetermined position in the tube storage area without using tools or other equipment, and by pivoting the tap head 20 downward to the closed position. path 10 can be maintained. Incidentally, when removing the beverage outlet path 10, it is possible to remove the beverage outlet path 10 by following the procedure opposite to that described above, so the explanation will be omitted.

Next, operations for pouring out a sparkling beverage, stopping pouring, and adding foam by the beverage pouring device 100 will be described with appropriate reference to FIGS. 5 to 10.
First, when no operating force is acting on the operating lever 70, the operating lever 70 of the beverage dispensing device 100 is at a stop position P0 in which the axis of the operating lever 70 is in an upright position, as shown in FIG. . When the operating lever 70 is at the stop position P0, the cam follower part 63 of the foaming piece 60 fits into the valley of the cam groove 46 of the slide piece 40, and the cam follower part 53 of the opening/closing piece 50 fits into the cam groove 45 of the slide piece 40. It fits into the valley of.

Therefore, both the opening/closing piece 50 and the foaming piece 60 are in a state of being advanced in the direction opposite to the flexible tube 11. At this time, both the opening/closing piece 50 and the foaming piece 60 press the flexible tube 11 into the desired state by the elastic force of the opening/closing spring 51 and the foaming spring 61. At this time, in the example of this embodiment, the opening/closing piece 50 completely closes the flow path in the opening/closing part, as shown in FIG. 9(b).

Note that, at this time, the foaming piece 60 is in a state in which the flow path in the foaming portion of the flexible tube 11 is narrowed to a predetermined value, as shown in FIG. 10(b). As a result, the effervescent beverage is maintained in the stopped state. In addition, the elastic forces of the opening/closing spring 51 and the foam spring 61 (or the elastic force of the slide spring 41 if there is one) are balanced, and the operating lever 70 stands on its own in a neutral position with its axis perpendicular. ing.

Next, in the beverage server 1 of this embodiment, when pouring the sparkling beverage into a glass, the operator, as shown in FIG. (toward the right in FIG. 6) until it reaches the first forward leaning posture (pour position P1).

When an operating force is applied to tilt the operating lever 70 forward until it reaches the first forward-leaning position, this causes the slide piece 40 to move rearward (leftward in FIG. 6) to a position corresponding to the first forward-leaning position. Move up to. Accordingly, due to the action of the cam described above, the convex cam follower of the opening/closing piece 50 moves along the front cam surface of the cam groove 45 of the slide piece 40 and above the middle part of the front cam surface, as shown in FIG. 9(a). As shown in , the flow path at the opening/closing section is opened. Furthermore, the convex cam follower of the foam making piece 60 moves upward along the front cam surface of the cam groove 45 of the slide piece 40 to the middle part thereof, and as shown in FIG. The flow path is also opened. This allows the sparkling beverage to be poured into a glass.

Here, in the beverage server 1 of this embodiment, as shown in FIG. It is configured so that it can be tilted to a forward leaning position.
When in the second forward leaning position, the effervescent beverage is located at a continuous pouring position P2 where the effervescent beverage is maintained in the pouring state. In other words, when pouring a sparkling beverage into a large container such as a pitcher, as shown in the same figure, move the operating lever 70 by hand from the pouring position P1 to the front side (toward the right in FIG. 7) when viewed from the operator side. ) (continuous injection position P2).

As a result, the slide piece 40 moves further toward the rear (to the left in FIG. 7) in accordance with the second forward-leaning posture. Accordingly, the convex cam follower of the opening/closing piece 50 climbs over the front cam surface of the cam groove 45 of the slide piece 40 to reach the ridge 44, and is pressed toward the horizontal surface of the top of the ridge 44.

In the pressed state, the elastic forces of the opening/closing spring 51 and the foam spring 61 (or the elastic force of the slide spring 41 if there is one) are balanced, and the operating force is applied to the operating lever 70. If no action is taken, the tilted posture will be maintained. As a result, the effervescent state of the sparkling beverage is maintained until further operating force is applied to the operating lever 70 to return the operating lever 70 from the continuous pouring position P2 to the stop position P0 where the operating lever 70 is in a neutral position. Can be poured continuously into large containers such as pitchers.

Next, in the beverage server 1 of the present embodiment, when adding foam to a glass, the operator, as shown in FIG. Push it toward the back (to the left in FIG. 8) when viewed from above (foaming position P3). As a result, the slide piece 40 moves forward (to the right in FIG. 8). Accordingly, the convex cam follower of the opening/closing piece 50 moves upward along the rear cam surface of the cam groove 45 of the sliding piece 40, and as shown in FIG. The flow path at is opened.

Further, the convex cam follower of the foaming piece 60 is pressed against the rear cam surface of the cam groove 46 of the slide piece 40, and as shown in FIG. The flow path is narrowed down to a predetermined value.
Particularly, in this embodiment, the flow path narrowing mechanism by advancing and retracting the foaming piece 60 moves the flexible tube 11 into the foaming piece at a position held in the concave accommodating parts of the front side holding part 81a and the rear side holding part 81b. It is elastically deformed by the opposing concave pressing portions 62 of 60 to create a restricted flow path within the beverage outlet path 10. Thereby, the cross-sectional area of the tube lumen is narrowed to create an orifice to generate bubbles, thereby making it possible to perform desired foaming.

As described above, according to the beverage dispensing device 100 of the present embodiment, the opening/closing piece 50 is a flexible tube that is converted by the action of the cam as the slide piece 40 slides in response to the tilting operation of the operating lever 70. 11, the flexible tube 11 can be opened and closed only by the elastic force of the opening and closing spring 51. Similarly, the foaming piece 60 foams the flexible tube 11 by moving back and forth with respect to the flexible tube 11, which is converted by the action of the cam as the sliding piece 40 slides in response to the tilting operation of the operating lever 70. Foam can be formed by squeezing only with the elastic force of the spring 61.

In other words, the beverage dispensing device 100 of the present embodiment employs a pressure adjustment method using only the spring pressure of the biasing springs 51 and 61, so that it can always press with a constant and stable pressing force. Therefore, like the technique disclosed in Patent Document 1, the cross-sectional area of the inner cavity of the flexible tube 11 after deformation can be stabilized to be substantially constant, regardless of the amount of force applied by the operator.
Therefore, according to the beverage dispensing device 100 of the present embodiment and the beverage server 1 equipped with the same, the manual operability is excellent, the foam quality can be easily adjusted, and the adjusted foam quality has high reproducibility. Therefore, it is possible to pour a sparkling beverage such as beer with stable foam quality [Inventions 1 and 13].

In this embodiment, the operating lever 70 shows an example of a configuration in which the slide piece 40 can be slid in response to the tilting operation, but regarding manual operability, the operating lever 70 is limited to the tilting operation. First, various modes can be adopted as long as the lever can be manually operated. For example, the operating lever 70 may also be configured to slide, and the slide piece 40 may be configured to be slidable in accordance with the sliding movement.

Further, according to the beverage dispensing device 100 of the present embodiment, the operating lever 70 has a stop position P0 where dispensing and foaming of the sparkling beverage is stopped, a dispensing position P1 where the sparkling beverage is dispensed, The cam mechanism is configured to be tiltable to a foaming position P3 for generating and dispensing foam of a sparkling beverage, and when the operating lever 70 is at the stop position P0, the cam mechanism is configured to move the opening/closing piece 50 and the foaming piece 60. is placed in an advanced position relative to the flexible tube 11.

Here, for example, like the technique described in Patent Document 1, it is also possible to set the foaming piece 60 to the retracted position when the foaming piece 60 is at the stop position P0.
However, as in this embodiment, by setting the foaming piece 60 to the forward position when it is at the stop position P0, foaming can be started immediately after starting the tilting operation of the operating lever 70 toward the foaming position P3. becomes.
In other words, in the case of the former setting, it is necessary to move the opening/closing piece 50 backward after the foaming piece 60 is moved to the forward position, which causes a time lag in foaming with respect to the tilting operation of the operating lever 70. Furthermore, if the opening/closing piece 50 is moved backward at the same time as the foam making piece 60 is advanced, there is a problem that the foam quality immediately after the tilting operation of the operating lever 70 is deteriorated.

Further, the cam mechanism of the present embodiment positions the opening/closing piece 50 and the foaming piece 60 in the retracted position with respect to the flexible tube 11 when the operating lever 70 is at the pouring position P1, and the operating lever 70 When in the attached position P3, the opening/closing piece 50 is placed in a retracted position with respect to the flexible tube 11, and the foaming piece 60 is placed in a forward position with respect to the flexible tube 11. Therefore, according to the beverage dispensing device 100 of the present embodiment, the tilting operation of the operating lever 70 and the corresponding cam mechanism provide a smooth interlocking operation, which provides the same excellent performance as the conventional manual beverage dispensing device. This is suitable for realizing a small and compact beverage dispensing device while maintaining operability [Invention 2].

In particular, according to the beverage dispensing device 100 of the present embodiment, when no operating force is acting on the operating lever 70, the operating lever 70 is located at the stop position P0 in which its own axis is in an upright posture, and the operating lever When the operating force for tilting the operating lever 70 toward the front side is applied and it is in the first forward leaning position, it is located at the pouring position P1, and when the operating force for tilting the operating lever 70 towards the rear side is acting and it is in the backward leaning position. Since it has a tilting motion that places it in the foaming position P3, it is possible to realize a small and compact beverage dispensing device while maintaining the excellent operability of a conventional manual beverage dispensing device. More suitable [Invention 3].

Furthermore, in the beverage dispensing device 100 of the present embodiment, as shown in FIG. When the operating lever 70 is in the continuous injection position P2, the mechanism can maintain its tilted posture as long as no operating force is applied to the operating lever 70. Therefore, according to the beverage dispensing device 100 of the present embodiment, the tilted posture is maintained, and not only can the sparkling beverage be poured into a glass, but also the sparkling beverage can be continuously poured into a large container such as a pitcher. It is more convenient because it allows pouring [Invention 4].

In addition, in the beverage dispensing device 100 of the present embodiment, as shown in FIG. 8, when the operating lever 70 is operated to the foaming position P3, the slide In order to maintain the non-operating state of the foaming piece 60 longer than the opening/closing piece 50 in the movement direction, the cam groove 46 for the foaming piece 60 has a cam groove in the sliding movement direction longer than the cam groove 45 for the opening/closing piece 50. The profile (bottom of the valley) is set wide (long).

Therefore, according to the beverage dispensing device 100 of the present embodiment, foam can be generated even when the operating lever 70 is not pushed all the way back (the beverage channel 10 is not completely opened). In other words, bubbles can be generated from a point in time when the tilt angle of the operating lever 70 from the neutral position is smaller. This makes it possible to more delicately adjust the foaming speed (amount) according to the tilting angle of the operating lever, and expand the foaming adjustment range for the tilting angle of the operating lever 70, allowing adjustment of the foaming speed (amount). becomes easier [Invention 5].

Moreover, according to the beverage dispensing device 100 of this embodiment, as shown in FIG. (54, 64), the pressing force of each can be adjusted individually. Therefore, it is suitable for easier adjustment of the pouring amount and foam quality of the sparkling beverage and for further improving the reproducibility of the adjusted pouring amount and foam quality [Invention 6].

Here, if the hollow cylindrical flexible tube 11 is simply pressed from above and below, the cross section of the inner lumen of the tube after deformation becomes an oval shape that is flat in the transverse direction. Therefore, due to slight differences in the amount of pushing by the pressing member pressing from above or slight dimensional errors in the tube, the cross section of the flat elliptical lumen after deformation may change significantly, and in some cases, the flow path may be blocked. There is also.
Furthermore, in a pressing method that creates two or more throttle channels in a beverage outlet channel, such as the technology described in Patent Document 1, the shape reproducibility of the two or more throttle channels is lower than that of a single throttle channel. It is relatively difficult to adjust the foam quality, and it is also relatively difficult to improve the reproducibility of the adjusted foam quality. In particular, in the case of a pressing method such as the technology described in Patent Document 1, if there are large dimensional errors in tubes or resin parts, problems such as failure to produce bubbles are likely to occur, and dimensional errors have a large effect on foam quality. .

On the other hand, according to the beverage dispensing device 100 of the present embodiment, the mechanism for squeezing the inner cavity by advancing and retracting the foaming piece 60 includes the concave pressing portion 62a of the foaming piece 60, Since the flexible tube 11 is elastically deformed at 62b to create a restricted flow path in the inner cavity of the flexible tube 11, the foam quality can be easily adjusted and the adjusted foam quality can be highly reproducible. [Invention 7]

In particular, in the beverage dispensing device 100 of this embodiment, as shown in FIG. A three-point clamping structure is adopted with a pair of left and right limiting side walls 62a and 62b formed on the inner surface of the pressing part 62 in a concave facing each other.
Thereby, according to the beverage dispensing device 100 of the present embodiment, the cross-sectional area of the tube inner cavity after being deformed by pressure from above and below can be stabilized to be substantially constant regardless of the amount of pushing and the dimensional error of the tube. Therefore, it has excellent manual operability, easy adjustment of foam quality, and high reproducibility of the adjusted foam quality, so it is extremely excellent in producing foam of stable quality.

In addition, according to the beverage dispensing device 100 of the present embodiment, since the tube holding part 81 that holds the flexible tube 11 in the concave storage part is provided, the flexible tube 11 at the position facing the foaming piece 60 is The position can be maintained reliably.
In particular, the tube holding part 81 of this embodiment has a front holding part 81a that holds the flexible tube 11 in a concave accommodating part at a position on the front side of the foaming piece 60 in the extending direction of the flexible tube 11. , a rear side holding part 81b that holds the flexible tube 11 in a concave accommodating part at a position on the rear side of the foaming piece 60 separated from the front side holding part 81a in the sliding direction, so that the foaming piece The flexible tube 11 can be reliably held at a position near the front and back of the tube 60.

Furthermore, in the beverage dispensing device 100 of the present embodiment, the front side holding part 81a and the rear side holding part 81b are such that the length of the holding part in the sliding direction (that is, the extending direction of the flexible tube 11) is Since the front side holding part 81a is shorter than the side holding part 81b, it is possible to securely hold the flexible tube 11 at a position near the front and back of the foaming piece 60 and to increase the length of the pipe on the extraction side. It can be shortened as much as possible. Therefore, it is suitable for producing foam of stable quality with easy adjustment of foam quality and high reproducibility of the adjusted foam quality [Invention 8].

Furthermore, according to the beverage dispensing device 100 of the present embodiment, the beverage outlet path 10 is configured to be easily inserted into and removed from the tube accommodating portion 80 by hand, so that special tools and fixing parts are not required. is no longer necessary, and the maintainability of replacing and installing the beverage outlet path 10 is also excellent [Invention 9].

In particular, in this embodiment, as shown in FIG. Since the tube joint 12 is configured to connect the flexible tube, the connecting tube, and the tube joint, each component of the flexible tube, the connecting tube, and the tube joint can be individually removed for maintenance. Note that the beverage outlet path 10 may be integrated so that each component cannot be removed. However, since the tip of the beverage outlet path 10 is more likely to become dirty (due to the higher temperature), it is preferable to configure the flexible tube 10 and subsequent parts to be detachable and replaceable.

The tube accommodating portion 80 includes, in order from the rear side, a connection tube accommodating groove 87 for accommodating the connection tube 13, a joint accommodating portion for accommodating the tube fitting 12, and a tube holder for accommodating and holding the flexible tube 11. 81, it is suitable for reliably holding each component of the beverage outlet path 10 in the desired position.

Moreover, according to the beverage dispensing device 100 of this embodiment, as shown in FIG. 2, the housing structure is configured by vertically overlapping the tap base 30 and the tap head 20. Furthermore, the flexible tube 11 is manually piped so that it is horizontally accommodated along the front-rear direction in a tube accommodating part 80 that is provided in the tap base 30 and holds the flexible tube 11 in a concave accommodating part. can.

The slide piece 40 is accommodated inside the tap head 20 so as to be slidable along the longitudinal direction of the flexible tube 11 within the tube accommodating portion 80, and the operating lever 70 is located at the upper front side of the tap head 20. Since the slide piece 40 is provided so that it can be slid by extending upward and tilting in the front-back direction, maintenance costs can be reduced by constructing the casing and main parts from as few parts as possible. It is suitable as a structure with excellent properties [Invention 10].

Furthermore, according to the beverage dispensing device 100 of the present embodiment, as shown in FIG. is connected to the tap base 30 so as to be openable and closable by a pivoting motion around the support shaft 23, and can be positioned in a usage position in which it is locked on the tap base 30 side and in a maintenance position in which it is rotated upward relative to the tap base 30. Therefore, the maintenance of the beverage outlet path 10 including the flexible tube 11 is excellent.

In particular, according to the beverage dispensing device 100 of the present embodiment, the tube fitting 12 is held between the tap base 30 and the tap head 20 in the use position, and the tap base is held in the maintenance position. The flexible tube is rotated to a position where the entire beverage outlet path 10 can be seen in the tube accommodating portion 80 on the upper surface of the tube 30, and the beverage outlet path 10 can be inserted and removed from the tube accommodating portion 80 without using tools. It can be said that the maintainability of the beverage outlet path 10 including 11 is extremely excellent [Invention 11].

Further, according to the beverage dispensing device 100 of the present embodiment, the beverage dispensing path 10 further includes a dispensing nozzle 90, as shown in FIGS. 3 and 4, and the dispensing nozzle 90 has an inner diameter Since it is formed into a truncated cone shape that gradually widens from the proximal end to the distal end, it is suitable for suppressing the generation of bubbles when pouring out a beverage.
In other words, if the inner diameter of the flexible tube 11 is too small relative to the flow rate, the flow of the beverage poured out from the spout 5 will become unstable, and bubbles will likely occur when the beverage is poured into a glass. Therefore, in the beverage dispensing device 100 of the present embodiment, the dispensing nozzle 90 whose inner diameter gradually widens is provided to rectify the flow and suppress the generation of bubbles when dispensing the beverage.

Further, according to the beverage dispensing device 100 of the present embodiment, in the usage position, the dispensing nozzle 90 (the nozzle holding plate 91 in this example) is pressed between the tap base 30 and the tap head 20. In the maintenance position, the beverage outlet path 10 including the pouring nozzle 90 can be inserted and removed from the tube accommodating portion 80 without using tools, which is more suitable as a structure with excellent maintainability. There is [Invention 12].

As described above, the beverage dispensing device 100 of the present embodiment and the beverage server 1 equipped with the same have excellent manual operability, easy adjustment of foam quality, and high reproducibility of the adjusted foam quality. expensive.
It should be noted that the beverage dispensing device according to the present invention and the beverage server equipped with the same are not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the spirit of the present invention. .
