Description

  The present invention relates to a beverage supply nozzle. More specifically, the present invention is applied to a beverage supply device such as a beverage dispenser and a cup-type vending machine, and discharges carbonated water generated inside the beverage supply device. It is about.

  Conventionally, for example, in beverage dispensers that are sold by mixing one syrup selected from a plurality of different syrups (concentrated liquids) and diluted water such as carbonated water or cold water, cold water and carbon dioxide gas are contained therein. And a carbonater for producing carbonated water by mixing the carbonated water, and the carbonated water produced by the carbonator is poured out from the beverage supply nozzle into the beverage container. A conventional example of this beverage supply nozzle will be described with reference to FIG.

  As illustrated in FIG. 6, the beverage supply nozzle 200 includes a hollow tubular body 201 and a resistor 202 inserted into the tubular body 201.

  A carbonated water introduction portion 203 is attached to the upper end of the tubular body 201, while the lower end is formed as a discharge port 204. In the middle region of the tubular body 201, a cold water introduction path 205 is formed so as to protrude radially outward, and a net 206 as a filter member is disposed inside.

  The resistor 202 is formed as a solid polygonal column made of a columnar body having a polygonal cross section (for example, a dodecagon), and has a head protruding in a conical shape. The resistor 202 is inserted into the hollow portion of the tubular body 201 so that the corners of the respective outer walls are in contact with the inner wall surface of the tubular body 201, whereby the flat portion of the outer wall of the resistor 202 and the inner wall surface of the tubular body 201 are inserted. A gap (pressure reduction part) is formed between the two.

  The carbonated water introduction unit 203 is configured so that carbonated water generated by mixing cold water and carbon dioxide gas by the carbonator 207 is supplied via the electromagnetic valve V1. The cold water introduction path 205 is configured such that cold water obtained by cooling tap water from a city water supply via a cooling water tank is supplied via an electromagnetic valve V2.

  In such a configuration, when a carbonated beverage-based beverage selection button provided on the operation panel of the beverage dispenser is pressed, the electromagnetic valve V1 is excited at a predetermined timing, and carbonated water is introduced from the carbonater 207 into the carbonated water introduction unit. It is pumped to 203. The carbonated water pumped to the carbonated water introduction portion 203 is evenly distributed along the conical head of the resistor 202, and then between the flat portion of the outer wall of the resistor 202 and the inner wall surface of the tubular body 201. Then, the liquid is discharged from the discharge port 204 through the gap formed.

  When a non-carbonated beverage selection button provided on the operation panel of the beverage dispenser is pressed, the electromagnetic valve V2 is excited at a predetermined timing and the discharge port of the tubular body 201 via the cold water introduction path 205. Cold water is discharged from 204 (see, for example, Patent Document 1).

JP 2012-144272 A

  According to the beverage supply nozzle disclosed in Patent Document 1, the carbonated water pumped to the carbonated water introduction unit 203 is formed between the flat portion of the outer wall of the resistor 202 and the inner wall surface of the tubular body 201. Since the pressure is reduced when passing through the gap, it is possible to prevent a decrease in gas volume due to the separation of carbon dioxide gas, and further, the head of the resistor 202 is formed in a conical shape so that carbonated water is contained in the head. When it collides with the gas, it flows in a distributed manner around the periphery without being generated, and is guided to the gap, so that separation of carbon dioxide gas generated by the generation of the vortex can be suppressed.

  By the way, the smaller the gap, the lower the gas volume due to the separation of the carbon dioxide gas when carbonated water passes, so the gap can be reduced by increasing the number of corners of the polygonal resistor 202.

  However, when the gap is reduced, the passing speed of carbonated water passing through the resistor 202 is lowered. This passage speed is proportional to the discharge time of carbonated water discharged from the beverage supply nozzle 200, and the discharge time for discharging a predetermined amount of carbonated water required for sale from the drink supply nozzle 200 becomes longer as the passage speed decreases. This means that the sales time of the beverage dispenser (the time from when the beverage selection button is pressed down to when a predetermined amount of beverage is poured into the beverage container) becomes longer. This sales time is an important sales factor, and a predetermined sales time must be secured.

  Therefore, if it is attempted to suppress a decrease in gas volume by reducing the gap, the sales time becomes longer. Therefore, in order to secure a predetermined sales time, the number of corners of the resistor 202 cannot be increased, and the gap There is a limit to making it smaller. In addition, in order to ensure sales time, if the diameter of the resistor 202 or the tubular body 201 is increased to increase the inner diameter of the tubular body 201 with which the corners of the resistor 202 are in contact, the beverage supply nozzle is suppressed while suppressing a decrease in gas volume. Although it is possible to ensure the discharge time of carbonated water from the 200, increasing the diameter of the resistor 202 and the tubular body 201 in this way is advantageous because the installation space for the beverage supply nozzle 200 must be secured. is not.

  An object of this invention is to provide the drink supply nozzle which can ensure predetermined discharge time, suppressing the fall of a gas volume in view of the said situation.

  In order to achieve the above object, a beverage supply nozzle according to the present invention is a beverage supply nozzle that decompresses and discharges supplied carbonated water, and includes a plurality of storage units that are partitioned from each other and arranged in parallel. A plurality of carbonated water introduction paths for introducing carbonated water supplied to the corresponding storage units, and in a form communicating with the respective storage units, and the carbonated water that has passed through each storage unit is provided. A nozzle body having a common discharge port for discharging, and a resistor that reduces the pressure by passing carbonated water through a gap between the nozzle body and the storage section, having a polygonal columnar cross section. It is characterized by having a body.

  Moreover, the present invention is characterized in that, in the beverage supply nozzle, the resistor causes carbonated water to pass through a gap formed between an outer wall flat surface portion of the beverage supply nozzle and an inner wall surface of the storage portion to reduce the pressure. .

  According to the present invention, since the cross section of the resistor housed in the housing portion forms a polygonal columnar body, the gap formed between the resistor and the housing portion can be reduced. Thus, it is possible to suppress a decrease in gas volume due to separation of carbon dioxide gas when carbonated water passes through the gap. In addition, since a plurality of storage units are provided and resistors are stored in each of the storage units, it is possible to increase the number of gaps, thereby increasing the amount of carbonated water passing per unit time. The amount of carbonated water can be discharged at a predetermined discharge time. Therefore, there is an effect that a predetermined discharge time can be secured while suppressing a decrease in gas volume.

Below the beverage supply nozzle 10, there are provided a cup rest 5 serving as a table for a cup as a beverage container, and a drip tray 6 for collecting scattered beverages and the like.

  Inside the dispenser body 2, although not shown in the figure, a tube-type pump that pumps a predetermined amount of syrup stored in a BIB (Bag In Box) stored in the refrigerator, and cooling diluted water (cold water) As is well known, a cooling water tank, a carbonator that is immersed in the cooling water tank to generate carbonated water (diluted water), a syrup and an electromagnetic valve for diluted water, and the like are installed.

  2 and 3 show the beverage supply nozzle 10 shown in FIG. 1, respectively. FIG. 2 is a side view and FIG. 3 is a longitudinal sectional view. As shown in FIGS. 2 and 3, the beverage supply nozzle 10 includes a nozzle body 20 and a resistor 30.

  The nozzle body 20 includes a tubular body 21a and a carbonated water introducing portion 21b. The tubular body 21a is a molded product of, for example, a synthetic resin, and has a cylindrical shape whose longitudinal direction is the longitudinal direction. The tubular body 21 a includes a storage unit 22, a discharge port 23, and a cold water introduction unit 24.

  A plurality of storage units 22 (two in the illustrated example) are provided, and are formed so as to be lined up on the left and right in a manner partitioned from each other. As shown in FIG. 4, these storage portions 22 have circular openings 22a at their upper ends, and are formed in such a manner that the cross-sectional area gradually decreases from the top to the bottom. That is, the storage portion 22 is formed in such a manner that the length of the diameter gradually decreases from the top to the bottom.

  The discharge port 23 is an opening formed in the lower end portion of the tubular body 21a. The discharge port 23 communicates with each storage portion 22 through a funnel-shaped channel 25 formed inside the tubular body 21a.

  The cold water introduction part 24 is a cylindrical part formed in the intermediate part of the tubular body 21a. The cold water introduction part 24 is formed in an intermediate portion of the tubular body 21a in such a manner that the cold water introduction part 24 is gradually inclined upward as it is separated from the tubular body 21a, and has a cold water introduction path 24a therein. The cold water introduction path 24 a communicates with the funnel-shaped flow path 25.

  Although not clearly shown in the figure, such a cold water introduction section 24 is connected with a cold water supply means for supplying cold water generated by cooling in a cooling water tank in a manner communicating with the cold water introduction path 24a.

  The carbonated water introduction part 21b is attached to the upper end of the tubular body 21a via an O-ring 26, and closes the circular opening 22a of each storage part 22. The carbonated water introduction part 21 b has a plurality of carbonated water introduction paths 27 provided corresponding to the storage part 22. These carbonated water introduction paths 27 respectively extend along the vertical direction and communicate with the corresponding storage portions 22.

  Although not clearly shown in the figure, carbonated water supply means for supplying high-pressure carbonated water generated by a carbonator is connected to the carbonated water introduction part 21 b in a manner communicating with each carbonated water introduction path 27. .

  A plurality of resistors 30 (two in the illustrated example) are provided, and one resistor 30 is housed in the housing portion 22 as will be described later. Such a resistor 30 is a solid columnar body, and has a body part 30a and a head part 30b.

  The body portion 30a is configured as a polygonal columnar body in which corner portions 31 and flat portions 32 are alternately formed along the circumferential direction on the outer wall thereof. The body portion 30a is formed in such a manner that the cross-sectional area gradually increases from the bottom to the top. The gradient from the lower side to the upper side of the outer wall of the trunk portion 30 a substantially matches the gradient from the lower side to the upper side of the inner wall of the storage unit 22. The diameter of the circle connecting the corner portions 31 of the outer wall at the upper end portion of the body portion 30 a is the same as the diameter of the inner wall at the upper end portion of the storage portion 22.

  The head portion 30b is provided integrally with the upper end portion of the body portion 30a, and is formed in a conical shape in such a manner that the cross-sectional area gradually decreases as the distance from the body portion 30a increases.

  As shown in FIG. 4, these resistors 30 are inserted into the storage portion 22 through the circular opening 22 a in such a manner that the head portion 30 b is above the tubular body 21 a before the carbonated water introduction portion 21 b is mounted. As a result, one by one is stored in the storage unit 22. In this case, the central axis of the resistor 30 is accommodated in the accommodating part 22 so as to substantially coincide with the central axis of the accommodating part 22.

  When one resistor 30 is housed in each housing part 22 in this way, the gradient from the lower side to the upper side of the outer wall of the body part 30a increases from the lower side to the upper side of the inner wall of the housing part 22 as described above. FIG. 5 shows that the diameter of the circle that substantially coincides with the gradient and that connects the corner 31 of the outer wall at the upper end of the body portion 30a matches the diameter of the inner wall at the upper end of the storage portion 22. As described above, all the corner portions 31 of the outer wall of the resistor 30 are in contact with the inner wall surface of the storage portion 22, and the pressure reducing portion is provided between all the flat portions 32 of the outer wall of the resistor 30 and the inner wall surface of the storage portion 22. A gap S is formed.

  In the beverage supply nozzle 10 having the configuration as described above, when the carbonated beverage-based beverage selection button 4 is pressed, carbonated water can be discharged as follows.

  When the carbonated beverage-based beverage selection button 4 is pressed, the carbonated water electromagnetic valve is excited at a predetermined timing, and the high-pressure carbonated water generated by mixing cold water and carbon dioxide gas by the carbonator is carbonated water. Supplied through supply means.

  The beverage supply nozzle 10 to which carbonated water is supplied through the carbonated water supply means introduces carbonated water into each storage portion 22 through each carbonated water introduction path 27. Here, the carbonated water introduced into each storage portion 22 is evenly dispersed along the head 30 b of the resistor 30 and then is reduced in pressure through the gap S.

  And the drink supply nozzle 10 sends out the carbonated water pressure-reduced in the accommodating part 22 to the funnel-shaped flow path 25, and discharges it from the discharge outlet 23 after that.

  On the other hand, in the beverage supply nozzle 10, when the non-carbonated beverage type beverage selection button 4 is pressed, cold water can be discharged as follows.

  By pressing the non-carbonated beverage selection button 4, the cold water electromagnetic valve is excited at a predetermined timing and cold water is supplied through the cold water supply means.

  The beverage supply nozzle 10 to which cold water is supplied through the cold water supply means introduces cold water into the funnel-shaped flow path 25 through the cold water introduction path 24 a and then discharges it from the discharge port 23.

  As described above, according to the beverage supply nozzle 10 according to the embodiment of the present invention, the transverse section of the resistor 30 (body part 30a) stored in the storage unit 22 forms a polygonal columnar body. As a result, the gap S formed between the resistor 30 and the storage portion 22 can be reduced, thereby reducing the gas volume due to separation of carbon dioxide when carbonated water passes through the gap S. Can be suppressed. In addition, since a plurality of storage units 22 are provided and the resistors 30 are stored in each of them, the number of the gaps S can be increased, thereby increasing the amount of carbonated water per unit time. A desired amount of carbonated water can be discharged at a predetermined discharge time. Therefore, a predetermined discharge time can be secured while suppressing a decrease in gas volume.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.
