Description

[Technical Field]

[0001] The present invention relates to a beverage dispenser for dispensing beverages. [Background technology]

[0002] Patent Document 1 discloses an invention of a beverage dispenser having a beverage dispense nozzle (beverage dispensing unit). This beverage dispenser includes multiple canisters for storing powdered ingredients used to make the beverage, a hot water tank for storing hot water for dissolving the powdered ingredients, multiple mixing bowls for mixing the powdered ingredients released from the canisters with the hot water released from the hot water tank, and a beverage dispenser nozzle for pouring the resulting beverage into a container such as a cup located below. The beverage dispenser nozzle includes a nozzle body having a flow path through which the beverage flows, and a flow rectifier plate provided on the beverage outlet side of the flow path of the nozzle body to rectify the flow of the beverage, preventing the beverage from splashing outside the container such as a cup when discharged from the beverage dispenser nozzle. The flow rectifier plate of this beverage dispenser nozzle has a cross shape in plan view, dividing the beverage flow path into four equal parts in the circumferential direction.

[0003] In this beverage dispenser, when preparing a beverage, powdered ingredients are released from the corresponding canister and poured into a mixing bowl via a chute, and hot water from a hot water tank is supplied to the mixing bowl via a hot water supply pipe, where the powdered ingredients are mixed and poured into a cup. At this time, the flow of the beverage flowing out of the beverage outlet of the beverage dispenser nozzle is regulated by a straightening plate to prevent it from splashing outside the cup.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-231585 Summary of the Invention [Problem to be solved by the invention]

[0005] In the beverage dispenser of Patent Document 1, a straightening plate is provided on the beverage dispense nozzle and the beverage dispense nozzle is positioned as close as possible to the cup, thereby preventing the beverage flowing from the beverage dispense nozzle from splashing outside the cup. While this beverage dispenser is capable of dispensing beverages into low-height containers such as cups, there is a need for the device to be able to dispense beverages into taller containers such as small water bottles and tumblers. In this case, by elevating the position of the beverage dispense nozzle, it becomes possible to dispense beverages from the beverage dispense nozzle into taller containers such as small water bottles and tumblers. However, even though the beverage dispense nozzle is provided with a straightening plate, the beverage dispense nozzle is positioned so far away from the low-height container such as a cup, which can cause the beverage flowing from the beverage dispense nozzle to splash outside the low-height container such as a cup.

[0006] Furthermore, the beverage dispenser of Patent Document 1 mixes powdered beverage ingredients with hot water to produce beverages such as tea and coffee. However, this type of beverage dispenser also dispenses soup-like beverages by mixing powdered ingredients containing dried ingredients such as parsley, seaweed, and green onions with hot water. The beverage dispenser nozzle of Patent Document 1 is equipped with a straightening plate, which is cross-shaped in plan view, dividing the beverage flow path into four equal parts in the circumferential direction. Ingredients such as parsley, seaweed, and green onions contained in soup-like beverages tend to get caught on the upper end of the cross-shaped straightening plate in plan view of the beverage dispenser nozzle, which is undesirable from the standpoint of hygiene of the beverage dispenser nozzle. The present invention aims to prevent beverages dispensed from a beverage dispenser from splashing outside a container such as a cup, and to prevent solids such as ingredients contained in the beverage from remaining in the beverage dispenser. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a beverage supply device that includes a beverage supply unit that is provided in a housing and that can supply a beverage produced by mixing a beverage ingredient with raw water for the beverage, and a mounting unit that is provided in the front of the housing and that can mount a container that receives the beverage supplied from the beverage supply unit, and the beverage supply unit is provided with a cylindrical beverage pouring unit that pours the beverage above the mounting unit, and the beverage pouring unit has an inner peripheral surface that is provided with a cylindrical beverage pouring unit. At positions spaced apart from each other in the circumferential direction protrude inward Multiple The flow straightening rib extends in the axial direction, Multiple The upper end of the flow straightening rib is inclined downward so that the protruding end side, which is the tip side of the protruding rib, is on the lower side. The protruding ends of the plurality of flow straightening ribs are spaced apart from each other at the radial center of the beverage pouring portion and hang down in parallel to form a passageway with the same width in the vertical direction through which the beverage passes. The present invention provides a beverage supply device characterized by the above.

[0008] In the beverage supply device configured as above, the inner circumferential surface of the beverage extracting portion is At positions spaced apart from each other in the circumferential direction protrude inwards Multiple The flow straightening rib extends in the axial direction, Multiple The upper end of the flow straightening rib is inclined downward so that the protruding end side, which is the tip side of the protruding rib, is on the lower side. The protruding ends of the plurality of straightening ribs are spaced apart from each other at the radial center of the beverage dispensing portion and hang down in parallel to each other to form a passageway of the same width in the vertical direction through which the beverage passes. The beverage flowing through the beverage outlet is Multiple The slope of the upper end of the flow straightening rib At the radial center of the beverage dispensing part The flow of water down the drain and collected in the container enhances the flow straightening effect. This makes it difficult for the beverage dispensed from the beverage dispenser to splash outside the container, even if the beverage dispenser is located at a height away from the mounting part. Also, even if the beverage contains solids such as ingredients, The upper ends of the straightening ribs are inclined downward so that the protruding ends, which are the tip ends of the protruding ribs, are on the lower side, and the protruding ends of the plurality of straightening ribs hang down parallel to each other while being spaced apart from each other at the radial center of the beverage dispensing section, forming a passageway with the same width in the vertical direction through which the beverage passes. Therefore, solids such as ingredients contained in the ingredients of the beverage flow down the passageway in the radial center of the beverage dispensing section due to the inclination of the upper ends of each straightening rib, and solids contained in the beverage flow through the passageway formed with the same width in the vertical direction. This makes it difficult for solid matter contained in the beverage to remain in the beverage dispensing portion.

[0009] In the beverage dispenser configured as described above, it is preferable to form an axially extending slit on the circumferential surface of the beverage dispenser at a circumferentially different position from the position where the flow straightening ribs are located. When the flow rate of beverage passing through the beverage dispenser decreases, some of the beverage flows down along the flow straightening ribs of the beverage dispenser, but some of the beverage flows down the inner circumferential surface at a position where the flow straightening ribs are not located, and may spread outward and splash from the outlet at the lower end. In contrast, if an axially extending slit is formed on the circumferential surface of the beverage dispenser at a circumferentially different position from the position where the flow straightening ribs are located, the beverage flowing through the beverage dispenser will draw air into the beverage dispenser through the slit, creating a negative pressure. The air drawn into the beverage dispenser through the slit will push the beverage flowing through the beverage dispenser toward the flow straightening ribs, making it easier for the beverage flowing through the beverage dispenser to flow down along the flow straightening ribs and less likely to flow through the outlet at the lower end where the flow straightening ribs are not located. As a result, the beverage flowing down the beverage pouring portion flows down along the flow straightening ribs and spreads outward from the pouring outlet at the lower end, making it less likely to splash.

[0010] In the beverage supply device configured as above, 、 It is preferable to form the slits between the plurality of straightening ribs in the circumferential direction of the beverage dispensing portion. In this case, the air sucked into the beverage dispensing portion through the slits is pushed toward the straightening ribs on both sides, making it easier for the beverage flowing inside the beverage dispensing portion to flow down along the straightening ribs inside the beverage dispensing portion and less likely to flow out of the outlet at the lower end where the straightening ribs are not located. As a result, the beverage flowing down the beverage dispensing portion flows down along the straightening ribs and is even less likely to splash outward from the outlet at the lower end.

[0011] In the beverage dispenser configured as described above, it is preferable that the lower end of the flow straightening rib be inclined downward so that the protruding end is downward, and that the lower end of the flow straightening rib protrudes downward from the outlet at the lower end of the beverage dispensing portion. In this way, the beverage passing through the beverage dispensing portion flows downward from the protruding end side of the lower end of the flow straightening rib protruding from the outlet at the lower end of the beverage dispensing portion, so that the beverage is less likely to remain at the outlet at the lower end of the beverage dispensing portion due to surface tension, and the beverage is less likely to drip from the beverage dispensing portion.

DETAILED DESCRIPTION OF THE INVENTION

[0013] An embodiment of the beverage supply device of the present invention will be described below with reference to the drawings. The beverage supply device 10 of the present invention is also called a beverage dispenser, and is capable of supplying five types of hot beverages, such as hot tea, containing hot water, and five types of cold beverages, such as cold tea, containing cold water (water), into a container such as a cup. This beverage supply device 10 can supply beverages not only to low-height containers such as cups, but also to tall containers such as small water bottles and tumblers. Furthermore, this beverage supply device 10 can supply beverages such as tea, which are prepared by mixing powdered ingredients with water or hot water, as well as soup, which is prepared by mixing powdered ingredients containing dried ingredients such as parsley, seaweed, and green onions with water or hot water.

[0014] As shown in Figures 1 to 4, the beverage supply device 10 has a beverage preparation chamber 20 at the front of a roughly rectangular parallelepiped housing 11 in which powdered ingredients such as tea are mixed with hot and / or cold water to prepare a beverage such as tea, and a machine chamber 21 at the rear of the housing 11, with the interior of the housing 11 being separated into the beverage preparation chamber 20 and the machine chamber 21 by a partition plate 22.

[0015] 1 to 4, the housing 11 includes a housing main body 12 that is open at the front side, and a front panel 13 that closes the front opening of the housing main body 12. The front panel 13 is supported on the right side of the housing main body 12 so as to be rotatable about a vertical axis. As shown in FIGS. 1 and 2, an opening 13a is formed in the center of the lower part of the front panel 13 in the left-right direction, and a mounting portion 23 for mounting a container such as a cup is provided at the lower part of the beverage preparation chamber 20 at the position where the opening 13a is formed. The mounting portion 23 in this embodiment is capable of mounting not only low containers such as cups, but also tall containers such as small water bottles and tumblers.

[0016] As shown in Figures 1 to 4, the placing section 23 includes a receiving section 24 on which a container such as a cup is placed, and a cover section 25 that covers the upper side of the receiving section 24. The receiving section 24 is formed in the shape of a tray, so that beverage spilling from a container such as a cup can flow downward. A circular recess 24a is formed on the upper surface of the receiving section 24 as a marker for placing a container such as a cup, and this circular recess 24a is located directly below the beverage dispensing section 42 (42A to 42E) of the beverage guide 40 from which the beverage prepared in the beverage supply section 30 is poured.

[0017] As shown in Figure 3, cover portion 25 has a height that allows tall containers such as small water bottles and tumblers to be placed on pedestal portion 24, and includes a rear wall, left and right walls, and an upper wall that cover the rear, left and right sides, and upper side of pedestal portion 24. A cutout portion 25a is formed in the front end portion of the upper wall of cover portion 25 in the center in the left-right direction, and this cutout portion 25a is located directly above recessed portion 24a of pedestal portion 24. Beverage dispensing portions 42 (42A to 42E) of beverage guide 40 are located inside cutout portion 25a, and cutout portion 25a has the function of positioning beverage dispensing portions 42 (42A to 42E) directly above recessed portion 24a, which serves as a marker for placing a container. A rib 25b protruding upward is formed on the peripheral edge of the upper surface of the upper wall of the cover portion 25 except for the front portion.The rib 25b not only increases the strength of the cover portion 25, but also abuts against the rear end portion of the leg 43 of the beverage guide 40 described later, thereby preventing the beverage guide 40 from rotating around the vertical axis.

[0018] As shown in Figure 3, the beverage preparation chamber 20 is provided with a beverage supply unit 30 that supplies beverages into containers placed on the placement unit 23. In this embodiment, the beverage preparation chamber 20 is provided with four beverage supply units 30 for supplying hot or cold water and powdered ingredients for four types of hot or cold beverages other than hot or cold water. Since the four beverage supply units 30 other than the hot or cold water supply units 30 have substantially the same configuration, the following explanation will mainly be made using one beverage supply unit 30.

[0019] 3 and 4, the beverage supply unit 30 supplies a beverage to a container placed on the placing unit 23, and includes a beverage production unit 31 that produces a beverage from raw water consisting of hot and / or cold water (cold water) and powdered ingredients for the beverage, and a beverage guide 40 that guides the beverage produced in the beverage production unit 31 to the container on the placing unit 23. The beverage production unit 31 includes a powdered ingredient container 32 that stores the powdered ingredients for the beverage, a mixing container 33 that mixes the powdered ingredients for the beverage with the raw water, and an agitator 34 that agitates and mixes the powdered ingredients and the raw water in the mixing container 33.

[0020] The powdered raw material container 32 stores powdered raw materials for a powdered beverage such as tea, and is detachably attached to a base 14 provided in the beverage preparation chamber 20. A powdered raw material outlet 32a is provided at the bottom of the powdered raw material container 32, and the powdered raw materials are discharged from the outlet 32a into the mixing container 33. A screw 32b is provided at the bottom of the powdered raw material container 32, and the drive of a motor 32d is transmitted to the screw 32b via a coupling member 32c. When the screw 32b is rotated by the rotation of the motor 32d, the powdered raw materials in the powdered raw material container 32 are discharged from the outlet 32a into the mixing container 33.

[0021] As shown in Figure 4, the mixing container 33 stirs and mixes the powdered ingredients with raw water consisting of hot and / or cold water, and is detachably supported on a base 14 provided in the beverage preparation chamber 20. The mixing container 33 is open at the bottom of the powdered ingredient container 32, and the powdered ingredients discharged from the discharge outlet 32a of the powdered ingredient container 32 are carried into the mixing container 33. A discharge outlet 33a is formed at the bottom of the mixing container 33, and the beverage stirred and mixed in the mixing container 33 is discharged from the discharge outlet 33a into a beverage guide 40 provided below.

[0022] 5, base 14 is provided with raw water supply port 14a for supplying raw water consisting of hot and / or cold water (cold water) into mixing container 33. Hot water supply unit 50 and cold water supply unit 60, which will be described later, are connected to raw water supply port 14a, and hot and / or cold water as raw water sent from hot water supply unit 50 and / or cold water supply unit 60 is supplied to mixing container 33 through raw water supply port 14a.

[0023] As shown in FIG. 4, the mixing vessel 33 is provided with an agitator 34. The agitator 34 includes an agitator motor 34a mounted on the base 14 at the rear of the mixing vessel 33, a rotating shaft 34d rotated by the agitator motor 34a, and a disk 34e attached to the tip of the rotating shaft 34d. A coupling magnet 34b is attached to the output shaft of the agitator motor 34a, and a coupling magnet 34c is attached to the base end of the rotating shaft 34d that faces the agitator motor 34a. The rotating shaft 34d is detachably coupled to the agitator motor 34a via the coupling magnets 34b and 34c, and the agitator motor 34a rotates the rotating shaft 34d via the coupling magnets 34b and 34c. The rotating shaft 34d extends above the discharge port 33a at the bottom of the mixing vessel 33, and a disk 34e is attached to the tip of the rotating shaft 34d above the discharge port 33a. A stirring blade 34f is provided on the underside of a disk portion 34e at the tip of the rotating shaft 34d, and the powdered ingredients and raw material water in the mixing container 33 are stirred and mixed by the rotation of the disk portion 34e to produce a beverage.

[0024] 3 and 6, beverage guide 40 guides the beverage produced in beverage production unit 31 to a container placed on mounting unit 23, and is supported on the upper side of cover unit 25 of mounting unit 23. Beverage guide 40 comprises shallow box-shaped guide units 41 (41A-41D) extending from below discharge outlet 33a of mixing container 33 to the center in the left-right direction at the front of mounting unit 23, beverage extraction units 42 (42A-42E) that extract the beverage, and a pair of left and right legs 43 for supporting cover unit 25, with guide units 41A-41D, beverage extraction units 42A-42E, and legs 43 being integrally formed.

[0025] As shown in Fig. 6, the guide sections 41 (41A to 41D) have a beverage passage that extends to the left-right center of the front of the mounting section 23, and this beverage passage is inclined downward so that the left-right center of the front of the mounting section 23 is at the bottom. The beverage produced in each beverage producing section 31 is guided by the guide sections 41 (41A to 41D) to the left-right center of the front of the mounting section 23. The guide sections 41 (41A to 41D) are provided with beverage extraction sections 42 (42A to 42D) downstream of the beverage passage, and as shown in Fig. 3, the beverage extraction sections 42 (42A to 42D; only 42A and 42D are shown in Fig. 3) are arranged above the recess 24a of the receiving base section 24 from the cutout section 25a formed in the cover section 25 of the mounting section 23. Beverage extraction units 42A, 42D extract beverages produced in the leftmost and rightmost beverage production units 31 and are disposed in front of beverage guide 40. Beverage extraction units 42B, 42C extract beverages produced in the second-from-the-left and second-from-the-right beverage production units 31 and are disposed behind beverage extraction units 42A, 42D in the front of beverage guide 40. Beverage extraction unit 42E is disposed in front of beverage guide 40 behind beverage extraction units 42B, 42C, and is connected to the outlet end of a fifth hot water delivery pipe 59e of hot water supply unit 50, which will be described later.

[0026] As shown in Figures 6 and 7, the beverage extraction portion 42 (42A to 42E) has a cylindrical shape with its axis in the vertical direction, and a passage through which the beverage passes is formed inside. As shown in Figures 6(b) and 7, flow straightening ribs 42a are formed on the inner peripheral surface of the beverage extraction portion 42 (42A to 42E) so as to extend in the axial direction of the beverage extraction portion 42, protruding radially toward the center. These flow straightening ribs 42a have the function of straightening the flow of beverage passing through the beverage extraction portion 42 and preventing it from spreading and splashing outside a container such as a cup placed directly below. The flow straightening ribs 42a are formed in three locations spaced at equal intervals around the circumference of the beverage extraction portion 42. Each straightening rib 42a protrudes shorter than the radius of the inner diameter of the beverage extraction portion 42, so that the protruding ends of the three straightening ribs 42a are spaced apart from one another, and a beverage passage extending vertically (axially) is formed in the radial center of the beverage extraction portion 42. Because the protruding ends of the three straightening ribs 42a do not abut against one another, the beverage passage inside the beverage extraction portion 42 is not divided into multiple sections in the horizontal direction.

[0027] As shown in Figure 7, the upper ends of the straightening ribs 42a of the beverage dispensing portion 42 are inclined downward so that the protruding ends are on the lower side, and the inclination of the straightening ribs 42a causes the beverage flowing through the beverage dispensing portion 42 to be collected in beverage passages formed on each protruding end side of the straightening ribs 42a at the radial center of the beverage dispensing portion 42. As a result, the beverage flowing through the beverage dispensing portion 42 is collected at the radial center, increasing the speed of the beverage, and is dispensed with an enhanced straightening effect. In addition, the lower ends of the straightening ribs 42a are inclined downward so that the protruding ends are on the lower side, and the beverage flowing through the beverage dispensing portion 42 is more likely to flow downward along the protruding end sides of the straightening ribs 42a. It should be noted that the straightening ribs 42a of the beverage pouring portion 42 shown in Figure 7 do not have the lower end on the protruding end side protruding downward from the outlet at the lower end of the beverage pouring portion 42, but if the lower end on the protruding end side of the straightening ribs 42a protrudes downward from the outlet at the lower end of the beverage pouring portion 42 as shown in Figure 8, the beverage in the beverage pouring portion 42 will tend to flow downward from the protruding end side of the straightening ribs 42a, and the beverage will not easily remain at the outlet at the lower end of the beverage pouring portion 42 due to surface tension, making it less likely that the beverage will drip from the beverage pouring portion 42.

[0028] As shown in Figures 3 and 6(a), outwardly protruding locking projections 44 are provided on the left side of beverage extraction portion 42A and the right side of beverage extraction portion 42D, and these locking projections 44 engage with the left and right side portions of cutout portion 25a of cover portion 25. By locking projections 44 engaging with the left and right side portions of cutout portion 25a of cover portion 25, beverage extraction portions 42 (42A to 42E) are positioned so that they are located directly above circular recess 24a, which serves as a marker for placing a container on receiving base portion 24. Also, as shown in Figure 3, the rear ends of left and right legs 43 provided on the lower part of beverage guide 40 engage with left and right ribs 25b provided on the upper surface of cover portion 25, so that beverage guide 40 does not rotate around the vertical axis above cover portion 25.

[0029] In this way, locking projection 44 locks into notch 25a of cover portion 25 to restrict left and right movement, and leg portion 43 locks into rib 25b of cover portion 25 to prevent rotation about the vertical axis, so beverage dispensing portion 42 (42A-42E) is positioned directly above recess 24a, and guide portions 41A-41D are positioned directly below outlet 33a of mixing container 33 of each beverage brewing portion 31, making them less likely to move. This prevents beverage guide 40 from shifting position above cover portion 25, making it less likely that beverage brewed in beverage brewing portion 31 will slip out of beverage guide 40 and be released, and making it less likely that beverage dispensed from beverage dispensing portion 42 will slip out of a container such as a cup and be poured out.

[0030] As shown in Fig. 9, hot water supply unit 50 supplies hot water as a raw material for a beverage to be received in a container such as a cup on mounting unit 23. Hot water supply unit 50 is provided with a hot water storage tank 51 that stores hot water as a raw material for a beverage, and a first water supply pipe 52 extending from a water supply source such as a tap is connected to hot water storage tank 51. First and second water supply valves 52a, 52b are installed in first water supply pipe 52, and water from the water supply source is supplied to hot water storage tank 51 by opening first and second water supply valves 52a, 52b.

[0031] The hot water storage tank 51 is provided with a heater 53 and a temperature sensor 54. The heater 53 heats the water (hot water) in the hot water storage tank 51 to generate hot water. The temperature sensor 54 detects the temperature of the water (hot water) in the hot water storage tank 51. The heater 53 is controlled to operate based on the temperature detected by the temperature sensor 54, and the hot water in the hot water storage tank 51 is heated (kept warm) by the heater 53 to a temperature suitable for drinking. In addition, the hot water storage tank 51 is provided with a water level sensor 55, which detects the water level in the hot water storage tank 51. The first and second water supply valves 52a, 52b are controlled to open and close based on the water level detected by the water level sensor 55, and the water (hot water) in the hot water storage tank 51 is maintained within a predetermined water level range.

[0032] A hot water supply pipe 56 is connected to the bottom of the hot water storage tank 51, and a hot water supply pump 57 is installed in the hot water supply pipe 56. Hot water in the hot water storage tank 51 is sent to the hot water supply pipe 56 by the hot water supply pump 57. In addition, first to fifth hot water delivery valves 58a to 58e, each consisting of a three-way valve, are installed in the hot water supply pipe 56, and first to fifth hot water delivery pipes 59a to 59e are connected to the first to fifth hot water delivery valves 58a to 58e. The outlet end of the first hot water delivery pipe 59a is connected to the raw water supply port 14a of the left beverage supply unit 30, the outlet end of the second hot water delivery pipe 59b is connected to the raw water supply port 14a of the second beverage supply unit 30 from the left, the outlet end of the third hot water delivery pipe 59c is connected to the raw water supply port 14a of the third beverage supply unit 30 from the left (second from the right), and the outlet end of the fourth hot water delivery pipe 59d is connected to the raw water supply port 14a of the right beverage supply unit 30. The outlet end of the fifth hot water delivery pipe 59e is connected to the beverage pouring section 42E of the beverage guide 40.

[0033] By operating the hot water supply pump 57 and opening any one of the first to fourth hot water delivery valves 58a to 58d, the hot water in the hot water storage tank 51 passes through the hot water delivery pipe 56 and the first to fourth hot water delivery pipes 59a to 59d corresponding to the opened first to fourth hot water delivery valves 58a to 58d, and is supplied into the mixing vessel 33. In addition, by operating the hot water supply pump 57 and opening the fifth hot water delivery valve 58e, the hot water in the hot water storage tank 51 passes through the hot water delivery pipe 56 and the fifth hot water delivery pipe 59e and is supplied to a container such as a cup placed on the placement portion 23.

[0034] As shown in Fig. 9, water supply unit 60 supplies cold water (water) that will be used as raw water for the beverage received in a container such as a cup on mounting unit 23. Water supply unit 60 is provided with a cooling tank 61 for generating cold water that will be used as raw water for the beverage, and cooling water is stored in cooling tank 61. Also, an evaporation pipe 62 of a refrigeration device is provided within cooling tank 61, and the cooling water in cooling tank 61 is cooled by the heat of vaporization of a refrigerant circulating through evaporation pipe 62 of the refrigeration device. A water cooling pipe 63 is provided within cooling tank 61 for cooling the water that will be used as raw water.

[0035] A second water supply pipe 64 extending from the first water supply pipe 52 immediately downstream of the first water supply valve 52a (between the first water supply valve 52a and the second water supply valve 52b) is connected to the water inlet end of the water cooling pipe 63, and water from a water supply source such as a city water supply is delivered to the water cooling pipe 63 in the cooling tank 61 through a part of the first water supply pipe 52 and the second water supply pipe 64.

In addition, by opening the first water supply valve 52a and the fifth cold water delivery valve 66e, water from the water supply source is sent through part of the first water supply pipe 52 and the second water supply pipe 64 to the water cooling pipe 63 of the cooling tank 61, where it is cooled and becomes cold water, and the cold water cooled in the water cooling pipe 63 in the cooling tank 61 is supplied to a container such as a cup placed on the placement portion 23 through the water supply pipe 65, the fifth cold water delivery pipe 67e, and the fifth hot water delivery pipe 59e.

[0037] 1 and 2, an operation panel unit 70 for dispensing a beverage from the beverage supply unit 30 is provided above the opening 13a on the front surface of the front panel 13. A display panel 71 for displaying the type of beverage is provided in the center of the operation panel unit 70 in the left-right direction, and a contact-type supply operation unit 72 and a non-contact-type supply operation unit 73 are provided adjacent to both the left and right sides of the display panel 71 on the operation panel unit 70 as supply operation units for operating to dispense a beverage from the beverage supply unit 30.

[0038] In this embodiment, five contact-type supply operation units 72A-72E for supplying five types of cold beverages are arranged vertically on the left side of display panel 71, and five non-contact-type supply operation units 73A-73E for supplying the same beverages as contact-type supply operation units 72A-72E are arranged to the left of contact-type supply operation units 72A-72E. Also, five contact-type supply operation units 72F-72J for supplying five types of hot beverages are arranged vertically on the right side of display panel 71, and five non-contact-type supply operation units 73F-73J for supplying the same beverages as contact-type supply operation units 72F-72J are arranged to the right of contact-type supply operation units 72F-72J. In addition, contact-type supply operation units 72A to 72E (non-contact-type supply operation units 73A to 73E) and contact-type supply operation units 72F to 72J (non-contact-type supply operation units 73F to 73J) for supplying the same beverage at different temperatures (cold and hot) are arranged side by side at the same height.

[0039] As shown in Figure 10, the beverage supply device 10 is equipped with a control device 80 that controls the supply of beverages to containers placed on the placement section 23, and the control device 80 is connected to the beverage ingredient delivery motor 32d, the stirring motor 34a, the first and second water supply valves 52a, 52b, the heater 53, the temperature sensor 54, the water level sensor 55, the hot water pump 57, the first to fifth hot water delivery valves 58a to 58e, the first to fifth cold water delivery valves 66a to 66e, and the operation panel section 70.

[0040] The control device 80 is equipped with beverage supply means for supplying beverages produced in the beverage supply unit 30, including a cold beverage supply means for supplying a cold beverage using cold water (cold water) cooled in the cooling tank 61 in an amount corresponding to the capacity of a container such as a cup, a cold water supply means for supplying cold water cooled in the cooling tank 61 to a container such as a cup, a hot beverage supply means for supplying a hot beverage using hot water in the hot water storage tank 51 in an amount corresponding to the capacity of a container such as a cup, and a hot water supply means for supplying hot water in the hot water storage tank 51 to a container such as a cup.

[0041] When an operation signal is input to control device 80 when one of contact supply operation units 72A-72D is pressed down, or when an operation signal is input when one of non-contact supply operation units 73A-73D is operated without contact by holding an object such as a finger over the front side of the unit, control device 80 executes cold beverage supply means corresponding to contact supply operation unit 72A-72D or non-contact supply operation unit 73A-73D to supply a cold beverage from beverage supply unit 30. When an operation signal is input to control device 80 when contact supply operation unit 72E is pressed down, or when an operation signal is input to control device 80 when non-contact supply operation unit 73E is operated without contact by holding an object such as a finger over the front side of the unit, control device 80 executes cold water supply means to supply cold water from beverage supply unit 30.

[0042] When an operation signal is input to control device 80 when one of contact supply operation units 72F-72I is pressed down, or when an operation signal is input when one of non-contact supply operation units 73F-73I is pressed down with an object such as a finger, the control device 80 executes the hot beverage supply means corresponding to contact supply operation unit 72F-72I or non-contact supply operation unit 73F-73I to supply a hot beverage from beverage supply unit 30. When an operation signal is input to control device 80 when contact supply operation unit 72J is pressed down, or when an operation signal is input to control device 80 when non-contact operation is performed by holding an object such as a finger, the control device 80 executes the hot water supply means to supply hot water from beverage supply unit 30.

[0043] Next, the control of the cold beverage supply means, cold water supply means, hot beverage supply means, and hot water supply means will be described. When an operation signal is input to the control device 80 by pressing one of the contact supply operation units 72A-72D, or an operation signal is input by non-contact operation by holding an object such as a finger over the front of one of the non-contact supply operation units 73A-73D, the control device 80 executes the cold beverage supply means. By executing the cold beverage supply means, the control device 80 activates the beverage ingredient delivery motor 32d of the beverage supply unit 30 corresponding to the contact supply operation unit 72A-72D or non-contact supply operation unit 73A-73D, and opens the first water supply valve 52a and the first to fourth cold water delivery valves 66a-66d corresponding to the contact supply operation units 72A-72D or non-contact supply operation units 73A-73D. The powdered ingredients in the powdered ingredient container 32 are transferred into the mixing container 33, and the cold water cooled in the cooling tank 61 is supplied into the mixing container 33. Furthermore, by operating the stirring motor 34a of the stirring device 34, the powdered ingredients of the beverage and the cold water supplied into the mixing container 33 are stirred and mixed to become a cold beverage, and the produced cold beverage is poured through the guide parts 41A to 41D from the beverage pouring parts 42A to 42D into a container such as a cup on the placing part 23, and the cold beverage is supplied to the user.

[0044] When an operation signal is input to the control device 80 by pressing the contact-type supply operation unit 72E or by holding an object such as a finger over the front of the non-contact-type supply operation unit 73E, the control device 80 executes the cold water supply means. By executing the cold water supply means stage, the control device 80 opens the first water supply valve 52a and the fifth cold water delivery valve 66e for a time period corresponding to the container. The cold water cooled in the cooling tank 61 is dispensed from the beverage dispensing unit 42E into a container such as a cup on the mounting unit 23, and the user is provided with cold water (cold beverage).

[0045] When an operation signal is input to the control device 80 by pressing one of the contact-type supply operation units 72F-72I, or by non-contact operation by holding an object such as a finger over the front side of one of the non-contact-type supply operation units 73F-73I, the control device 80 executes the hot beverage supply means. By executing the hot beverage supply means, the control device 80 activates the beverage ingredient delivery motor 32d of the beverage supply unit 30 corresponding to the contact-type supply operation unit 72F-72I or the non-contact-type supply operation unit 73F-73I, operates the hot water pump 57, and opens the first to fourth hot water delivery valves 58a-58d corresponding to the contact-type supply operation unit 72F-72I or the non-contact-type supply operation unit 73F-73I. The powdered ingredients in the powdered ingredient container 32 are delivered to the mixing container 33, and the hot water in the hot water storage tank 51 is supplied to the mixing container 33. In addition, by operating the stirring motor 34a of the stirring device 34, the powdered ingredients of the beverage and the hot water supplied into the mixing container 33 are stirred and mixed to become a hot beverage, and the resulting hot beverage is poured through the guide sections 41A to 41D and from the beverage pouring sections 42A to 42D into a container such as a cup on the placing section 23, and the hot beverage is supplied to the user.

[0046] When an operation signal is input to the control device 80 by pressing the contact supply operation unit 72J or by a non-contact operation by holding an object such as a finger over the front side of the non-contact supply operation unit 73J, the control device 80 executes the hot water supply means. By executing the hot water supply means, the control device 80 operates the hot water pump 57 for a time according to the container and opens the fifth hot water delivery valve 58e. The hot water in the hot water storage tank 51 is dispensed from the beverage dispensing unit 42E into a container such as a cup on the placing unit 23, and the hot water (hot beverage) is supplied to the user.

[0047] The beverage dispenser 10 configured as described above comprises a beverage dispenser 30 provided within the housing 11 and capable of dispensing a beverage produced by mixing beverage ingredients with beverage ingredient water, and a mounting portion 23 provided at the front of the housing 11 for mounting a container that will receive the beverage dispensed from the beverage dispenser 30. The mounting portion 23 of the beverage dispenser 10 of this embodiment is capable of mounting tall containers such as small water bottles and tumblers in addition to low containers such as cups.

[0048] The beverage supply unit 30 includes a beverage preparation unit 31 that prepares a beverage, and a beverage guide 40 that guides the beverage prepared in the beverage preparation unit 31 to a container such as a cup placed on the placement unit 23. The beverage guide 40 includes a cylindrical beverage dispensing unit 42 (42A-42E) that dispenses the beverage above the placement unit 23. Since tall containers such as small water bottles and tumblers can also be placed on the placement unit 23, when a low-height container such as a cup is placed on the placement unit 23, the beverage dispensing unit 42 (42A-42E) is separated in height from the low-height container such as a cup. In contrast, in this beverage supply device 10, the inner peripheral surface of the beverage dispensing unit 42 (42A-42E) has flow straightening ribs 42a that protrude inward and extend in the axial direction, and the upper end of the flow straightening rib 42a is inclined downward so that the protruding end side, which is the tip side of the radially protruding tip, is on the lower side.

[0049] The inclination of the upper ends of the straightening ribs 42a causes the beverage flowing down the beverage dispensing portion 42 (42A to 42E) to flow down towards the protruding end and collect, thereby enhancing the downward flow straightening effect. In this embodiment, the straightening ribs 42a are formed in three locations on the inner peripheral surface of the beverage dispensing portion 42 at equally spaced positions in the circumferential direction, and the protruding ends of the three straightening ribs 42a are arranged so as to be spaced apart from one another so as to form a passage through which the beverage passes at the radial center of the beverage dispensing portion 42. The inclination of the upper ends of the three straightening ribs 42a causes the beverage flowing down the beverage dispensing portion 42 to collect at the radial center of the beverage dispensing portion 42, and the beverage flows down the passage at the center of the beverage dispensing portion 42, thereby enhancing the downward flow straightening effect compared to when a single straightening rib 42a is provided. This makes it possible to place tall containers such as small water bottles and tumblers on the placing section 23, and even if the beverage extraction section 42 (42A to 42E) is separated in height from a small container such as a cup placed on the placing section 23, the beverage extracted from the beverage extraction section 42 (42A to 42E) will not splash out from the small container such as a cup.

[0050] Furthermore, in this beverage dispenser 10, when powdered ingredient container 32 contains powdered ingredients containing dried ingredients (solids) such as parsley, laver, and green onion, beverages such as soup and clear soup can be dispensed by mixing the powdered ingredients containing the dried ingredients (solids) with hot or cold water. Because the resulting beverages, such as soup and clear soup, contain solid ingredients such as parsley, laver, and green onion, these solid ingredients may become trapped on the upper end of flow rectifying rib 42a and remain in beverage dispensers 42A-42D other than beverage dispenser 42E, which dispenses cold or hot water. The slope of the upper end of flow rectifying rib 42a prevents solid ingredients from remaining at the upper end, reducing the likelihood of solid ingredients contained in the beverage remaining in beverage dispensers 42A-42D. As described above, in this embodiment, the flow straightening ribs 42a are formed at three positions equidistantly spaced apart in the circumferential direction on the inner peripheral surface of the beverage dispensing portion 42, and the protruding ends of the three flow straightening ribs 42a are spaced apart from one another to form a passage through which the beverage passes at the radial center of the beverage dispensing portions 42A-42D. The inclination of the upper ends of the three flow straightening ribs 42a causes the beverage flowing down the beverage dispensing portions 42A-42D to collect at the radial center of the beverage dispensing portions 42A-42D. Solid matter, such as ingredients, contained in the beverage flowing through the beverage dispensing portions 42A-42D is collected at the protruding ends of each flow straightening rib 42a in the passage at the radial center of the beverage dispensing portions 42A-42D, and the beverage flows faster, so that it flows out without remaining inside the beverage dispensing portions 42A-42D.

[0051] 8, the lower ends of the flow straightening ribs 42a of the beverage extraction portions 42 (42A to 42E) are inclined downward so that the protruding end side is downward, and the lower ends of the flow straightening ribs 42a protrude downward from the outlets at the lower ends of the beverage extraction portions (42A to 42E). As the beverage passing through the beverage extraction portion 42 flows downward from the protruding end side of the lower ends of the flow straightening ribs 42a protruding from the outlets at the lower ends of the beverage extraction portions (42A to 42E), the beverage is less likely to remain at the outlets at the lower ends of the beverage extraction portions (42A to 42E) due to surface tension, and the beverage is less likely to drip from the beverage extraction portions (42A to 42E).

[0052] In the beverage dispenser 10 of the above embodiment, when a beverage is dispensed from the beverage dispensing portion 42 (42A-42E), if the flow rate of the beverage is high, such as at the start of beverage dispensing, the beverage flows down toward the protruding end due to the slope of the upper ends of the flow straightening ribs 42a and is collected, resulting in a high flow straightening effect as it flows downward from the outlet at the lower end. When the flow rate of the beverage decreases in the latter half of beverage dispensing, the flow straightening effect of the flow straightening ribs 42a within the beverage dispensing portion 42 decreases, and the beverage begins to flow down along parts of the inner circumferential surface of the beverage dispensing portion 42 where the flow straightening ribs 42a are not formed. In this case, the beverage that flows down along parts of the beverage dispensing portion 42 where the flow straightening ribs 42a are not formed flows outward along the underside of the beverage dispensing portion 42 as it flows out from the outlet at the lower end of the beverage dispensing portion 42, and there is a risk that the beverage will splash outward from the beverage dispensing portion 42 and not be received by a container, resulting in splashing around.

[0053] In particular, if the circumferential length of the portion between the flow straightening ribs 42a of the beverage dispensing portion 42 is long, the beverage tends to flow along the underside of the beverage dispensing portion 42 when it flows out from the outlet at the lower end of the beverage dispensing portion 42, making it more likely to splash outward. In contrast, if the number of flow straightening ribs 42a is increased, the circumferential length of the portion between the flow straightening ribs 42a of the beverage dispensing portion 42 becomes shorter, making it more difficult for the beverage to flow along the underside of the beverage dispensing portion 42 when it flows out from the outlet at the lower end of the beverage dispensing portion 42, making it less likely for the beverage to splash outward. However, if the number of flow straightening ribs 42a is increased, dried ingredients such as parsley, seaweed, and green onions are more likely to get caught on the flow straightening ribs 42a and remain, and the dispensing speed of the beverage from the beverage dispensing portion 42 slows.

[0054] In contrast, in the beverage dispenser 10 of the embodiment shown in Figures 11 and 12, axially extending slits 42b are formed on the circumferential surface of the cylindrical beverage dispensing portion 42 (42A-42E) at positions different in the circumferential direction from the positions where the flow straightening ribs 42a are disposed. In this embodiment, the flow straightening ribs 42a are formed at three positions equally spaced apart in the circumferential direction of the beverage dispensing portion 42, and the slits 42b are formed at three positions equally spaced apart in the circumferential direction of the beverage dispensing portion 42 on the inner circumferential surface of the beverage dispensing portion 42, in the circumferential central portion between the flow straightening ribs 42a. Furthermore, the flow straightening ribs 42a extend over substantially the entire axial length of the inner circumferential surface of the beverage dispensing portion 42, while the slits 42b extend from slightly below approximately the axial central portion of the beverage dispensing portion 42 to the lower end. Since the upper end of the slit 42b is not formed at a high position in the axial direction of the beverage extraction portion 42, the beverage does not flow out from the slit 42b when the beverage is being extracted from the beverage extraction portion 42.

[0055] In the beverage dispenser 10 of this embodiment, when a beverage is dispensed from the beverage dispenser 42, if the flow rate of the beverage is high, such as at the start of beverage dispensing, the inclination of the upper end of the rectifying rib 42a causes the beverage to flow down toward the protruding end and be collected, resulting in a high rectifying effect as the beverage flows downward. If the flow rate of the beverage is high, such as at the start of beverage dispensing, the beverage is dispensed from the dispensing outlet at the lower end with an increased rectifying effect of the rectifying rib 42a causing the beverage to flow downward.

[0056] When the flow rate of the beverage decreases in the latter half of beverage dispensing, the flow of beverage down beverage dispensing portion 42 causes air to be sucked into beverage dispensing portion 42 through slits 42b under negative pressure, and the beverage flowing down within beverage dispensing portion 42 is pushed towards rectifying ribs 42a by the air sucked through slits 42b, thereby achieving the rectifying effect of rectifying ribs 42a to cause the beverage to flow downward. As a result, even from the start of beverage dispensing to the latter half of beverage dispensing, the beverage flowing down within beverage dispensing portion 42 is dispensed from the outlet at the lower end with an enhanced rectifying effect of downward flow due to the rectifying ribs, and is received in the container without splashing out of beverage dispensing portion 42. In particular, in the beverage dispenser 10 of this embodiment, the slits 42b are formed between the flow straightening ribs 42a in the circumferential direction of the beverage dispensing portion 42, so that air sucked into the beverage dispensing portion 42 through the slits 42b is pushed toward the flow straightening ribs on both sides, making it easier for the beverage flowing inside the beverage dispensing portion to flow down along the flow straightening ribs 42a inside the beverage dispensing portion 42 and less likely to flow out of the outlet at the lower end where the flow straightening ribs 42a are not located. As a result, the beverage flowing down the beverage dispensing portion 42 flows down along the flow straightening ribs and is less likely to splash outward from the outlet at the lower end.

[0057] In the beverage dispenser 10 of each of the above-described embodiments, the flow straightening ribs 42a of the beverage dispensing portion 42 are formed in three locations spaced equally apart in the circumferential direction, but this is not limited to this, and the flow straightening ribs 42a may be formed in only one location on the inner circumferential surface of the beverage dispensing portion 42, or the flow straightening ribs 42a may be formed in two or more locations on the inner circumferential surface of the beverage dispensing portion 42. Similarly, in the embodiments in which the slits 42b are formed in the beverage dispensing portion 42, the slits 42b of the beverage dispensing portion 42 are formed in three locations circumferentially different from the locations where the flow straightening ribs 42a are disposed, and each slit 42b is formed between the flow straightening ribs 42a in the circumferential direction of the beverage dispensing portion 42, but this is not limited to this, and the slits 42b may be formed in only one location on the circumferential surface of the beverage dispensing portion 42, or the slits 42b may be formed in two or more locations on the inner circumferential surface of the beverage dispensing portion 42.

[0058] Furthermore, when the flow straightening rib 42a is formed at only one location on the inner circumferential surface of the beverage pouring portion 42, it is preferable to form each of the flow straightening ribs 42a of the five beverage pouring portions 42A-42E so as to protrude outward from the center of the beverage guide 40, as shown in Fig. 13. In this case, when the flow rate of the beverage decreases, such as in the latter half of pouring when the beverage is being poured from each of the beverage pouring portions 42A-42E, the poured beverage is guided by the flow straightening rib 42a, which makes it easier for the poured beverage to flow toward the center of the beverage guide 40, and the beverage is less likely to fall out of a container such as a cup placed in the recess 24a of the receiving base 24. Note that when the flow straightening rib 42a is formed at only one location on the inner circumferential surface of the beverage pouring portion 42, the flow straightening rib 42a may protrude longer or shorter than the center of the beverage pouring portion 42, as long as it does not reach the inner circumferential surface on the radially opposite side of the beverage pouring portion 42.

[0059] In the beverage dispenser 10 of this embodiment, the beverage guide 40 is provided with five beverage dispensing portions 42, but this is not limited to this and the beverage guide 40 may be provided with one or more beverage dispensing portions 42. Furthermore, in the beverage dispenser 10 of the above embodiment, all of the beverage dispensing portions 42 are provided with the flow straightening rib 42a described in the claims of the present application, but this is not limited to this and some of the beverage dispensing portions 42 may be provided with the flow straightening rib 42a described in the claims of the present application.
