Description

Technical Field

[0001] The present invention relates to a beverage machine. Background Art

[0002] In recent years, the way of dealing with beverages has been diversified, for example, a lifestyle of not consuming alcoholic beverages such as Sober Curious has been advocated. In addition, even for those who like alcoholic beverages, the trend of consuming low-alcohol beverages or non-alcoholic beverages according to their mood and physical condition at the time is also increasing. As a result, the demand for the alcohol concentration or taste concentration of beverages provided by restaurants and the like is diversifying, and there is a demand for providing beverages with customized concentrations.

[0003] For example, Patent Document 1 discloses a beverage supply device, characterized in that, in a beverage supply device for supplying a liquid raw material and carbonated water constituting a carbonated beverage to a single cup, a liquid raw material nozzle for supplying the liquid raw material and a carbonated water nozzle for supplying carbonated water are independently provided. However, the purpose of such a beverage supply device is to improve the mixing state of the beverage, that is, to suppress the generation of bubbles and suppress the decrease in gas volume, rather than to accurately customize the alcohol concentration of the beverage. In addition, if it is assumed that these beverage supply devices are used to provide beverages of various alcohol concentrations, it is necessary to increase the number of nozzles for pouring the beverages, and it is necessary to prepare many beverage storage tanks of different alcohol concentrations, but since it will lead to a large-scale beverage supply device and require an expanded installation space, it is difficult to install it in a general restaurant or the like.

[0004] Patent Literature Patent Document 1: Japanese Patent Application Publication No. 2003-137396 Summary of the invention

[0005] In view of the above-mentioned problems, an object of the present invention is to provide a beverage machine capable of accurately customizing the concentration of non-alcoholic beverages and alcoholic beverages.

[0006] One form disclosed by the present invention is a beverage machine for providing beverages, characterized in that the beverage machine comprises: a beverage dispensing portion having at least one of a first dispensing nozzle, a second dispensing nozzle and a third dispensing nozzle, including the first dispensing nozzle or the second dispensing nozzle, for dispensing beverages; a first pump connected to a first storage tank and used for pressurizing a first liquid contained in the first storage tank; a first supply pipe connecting the first storage tank and the first dispensing nozzle, through which the first liquid pressurized from the first storage tank flows; a first adjustment mechanism disposed in the middle of the first supply pipe and capable of adjusting the flow rate of the first liquid supplied to the first dispensing nozzle; a second pump connected to a second storage tank and used for pressurizing a second liquid contained in the second storage tank; The second supply pipe connects the second storage tank with the second discharge nozzle, and the second liquid pressure-sent from the second storage tank flows; the second adjustment mechanism is arranged in the middle of the second supply pipe, and can adjust the flow rate of the second liquid supplied to the second discharge nozzle; the third supply pipe connects the third liquid supply part for supplying the third liquid with the third discharge nozzle, and the third liquid from the third liquid supply part flows; and the control device can control the discharge amount of the first liquid supplied to the first discharge nozzle by linking the first pump with the first adjustment mechanism, and can control the discharge amount of the second liquid supplied to the second discharge nozzle by linking the second pump with the second adjustment mechanism, so as to adjust the concentration of the beverage poured from the beverage pouring part. In addition, the "concentration" mentioned here is not limited to the alcohol concentration, for example, it includes all the following concentrations as indicators when making beverages, namely: the concentration of the concentrate when diluting the concentrated concentrate to make the beverage; and the sugar content, salt concentration and pH concentration of the beverage when adjusting the sweetness, saltiness, sourness and fragrance.

[0007] Furthermore, as another form disclosed in the present invention, there is a first solenoid valve arranged on the beverage pouring portion for opening and closing the first ejection nozzle, and a second solenoid valve for opening and closing the second ejection nozzle, and a control device is electrically connected to the first solenoid valve and the second solenoid valve, and is constructed to be able to control the time of opening the first ejection nozzle and the second ejection nozzle.

[0008] Furthermore, as another aspect disclosed in the present invention, an operation unit is provided, the operation unit is electrically connected to the control device, and is configured to be able to set the concentration of the beverage poured from the beverage pouring unit.

[0009] According to one form disclosed in the present invention, the first liquid contained in the first storage tank is pumped by the first pump and discharged from the first discharge nozzle of the beverage dispensing portion through the first supply pipe. A first adjustment mechanism is arranged in the middle of the first supply pipe, which can adjust the flow rate of the first liquid supplied to the first discharge nozzle. In addition, the second liquid contained in the second storage tank is pumped by the second pump and discharged from the second discharge nozzle of the beverage dispensing portion through the second supply pipe. A second adjustment mechanism is arranged in the middle of the second supply pipe, which can adjust the flow rate of the second liquid supplied to the second discharge nozzle. Therefore, the discharge amount of the beverage discharged from the first discharge nozzle and the second discharge nozzle can be adjusted.

[0010] Furthermore, according to one form disclosed in the present invention, the control device can control the flow rate of the first liquid supplied to the first discharge nozzle by interlocking the first pump with the first adjustment mechanism, and can control the flow rate of the second liquid supplied to the second discharge nozzle by interlocking the second pump with the second adjustment mechanism. Therefore, for example, when the first liquid or the second liquid is an alcoholic beverage and the other liquid is a non-alcoholic beverage or water, the concentration of the beverage prepared by mixing them can be accurately customized. In addition, for example, when a non-alcoholic beverage is contained in the first tank or the second tank and the beverage is poured only using the first discharge nozzle or the second discharge nozzle connected to the tank, a non-alcoholic beverage can be prepared. Thus, the concentration of beverages including non-alcoholic beverages can be accurately customized.

[0011] Furthermore, according to one aspect disclosed in the present invention, for example, when an alcoholic beverage is contained in one of the first tank and the second tank and a non-alcoholic beverage is contained in the other, the alcoholic beverage and the non-alcoholic beverage can be respectively poured out from the first discharge nozzle and the second discharge nozzle. Therefore, when a non-alcoholic beverage is prepared using only the discharge nozzle connected to the tank containing the non-alcoholic beverage, mixing of alcohol can be prevented or suppressed.

[0012] Furthermore, according to one form disclosed in the present invention, a first electromagnetic valve for opening and closing the first ejection nozzle and a second electromagnetic valve for opening and closing the second ejection nozzle are arranged on the beverage pouring portion. The control device is configured to control the time of opening the electrically connected first electromagnetic valve and the second electromagnetic valve. Therefore, the amount of the first liquid and the second liquid poured from the first ejection nozzle and the second ejection nozzle can be accurately adjusted, and the concentration of the beverage made by mixing them can be adjusted. Thus, the concentration of beverages including non-alcoholic beverages can be accurately customized.

[0013] Furthermore, according to one aspect of the present invention, the concentration of the beverage dispensed from the beverage dispensing unit can be set using the operating unit electrically connected to the control device, thereby enabling the concentration of the beverage to be accurately customized.

DETAILED DESCRIPTION

[0015] Hereinafter, the beverage machine according to the embodiment will be described with reference to the accompanying drawings. The same or corresponding elements are marked with the same reference numerals, and repeated descriptions are omitted. For ease of understanding, the scale of the drawings may be changed for description.

[0016] Figure 1 A three-dimensional view of a beverage machine 10 is shown. In the beverage machine 10, a first beverage pouring part 14 and a second beverage pouring part 18 as beverage pouring parts are formed on the upper side of the front of the main body 12. Nozzle groups 16 and 20 for pouring alcoholic beverages or non-alcoholic beverages are respectively installed on the first beverage pouring part 14 and the second beverage pouring part 18. In addition, although the following description is made of a case where a plurality of nozzles are installed as the nozzle groups 16 and 20, it is not limited to this. For example, only one unified nozzle may be installed, and different types of liquids transported from different pipes may be mixed in the unified nozzle before pouring.

[0017] The alcoholic beverages mentioned here include, for example, beer, alcoholic carbonated beverages other than beer, i.e., sparkling wine, beer-flavored sparkling alcoholic beverages infused with other alcoholic beverages made from raw materials other than malt (so-called third beer), carbonated shochu, sour cocktails, plum wine soda, spirit soda, sparkling sake, sparkling wine, or ice whiskey soda (highball), etc. In addition, non-alcoholic beverages include non-alcoholic carbonated beverages, i.e., non-alcoholic beer, non-alcoholic spirits, non-alcoholic wine, non-alcoholic sour drinks, non-alcoholic cocktails, or carbonated fruit juices, etc. In addition, these beverages also include concentrated beverages (original solutions).

[0018] A bracket 22 is mounted below the nozzle groups 16 and 20 to hold a drinking container (not shown) for injecting beverages. In addition, an operation unit 24 for setting the alcohol concentration of the injected beverage is arranged on the front side of the beverage machine 10. The operation unit 24 has a touch screen 26, and the user can set the alcohol concentration of the beverage by operating the touch screen 26 (see FIG. Figure 4In addition, the operation unit 24 also has a function of inputting and setting the concentration of the beverage to be poured and the amount of the beverage poured from the nozzle groups 16 and 20. The user can set the amount of the beverage to be poured by operating the touch screen 26 (see Figure 3 ).

[0019] Figure 2 A block diagram of a beverage machine 10 is shown. The beverage machine 10 is provided with a clean water supply unit 30 as a third liquid supply unit, and the third liquid supply unit is used to supply clean water as a third liquid. The clean water supply unit 30 has a water source 32 of clean water, a regulator 34, and a filter 36, which are connected by a rear clean water pipe PA1 as a third supply pipe. The rear clean water pipe PA1 is made of polyethylene, for example. In addition, it is not limited to this, and it can also be made of other flexible materials such as synthetic resin. The clean water of the water source 32 is transported to the impeller pump 37 arranged on the main body 12 of the beverage machine 10 through the regulator 34 and the filter 36, that is, it flows. In addition, the water source of the clean water can be either a storage tank for storing clean water or a tap water pipe for supplying clean water.

[0020] The clean water delivered to the impeller pump 37 is discharged toward the carbonator 38. The carbonator 38 is connected to the carbon dioxide cylinder 40 through the regulator 42 and the air pipe PA2. Therefore, by dissolving the carbon dioxide regulated to a specified pressure into the clean water delivered to the carbonator 38, carbonated water can be generated. The carbonated water generated by the carbonator 38 is cooled by a cooling unit 44 having a cooling coil (not shown), and is delivered to the first beverage pouring unit 14 and the second beverage pouring unit 18 through the front clean water pipe PA3 as the third supply pipe. The front clean water pipe PA3 is, for example, made of polyethylene. In addition, it is not limited to this, and other flexible materials such as synthetic resins can also be used to manufacture. The carbonated water delivered to the first beverage pouring unit 14 can be poured out from the clean water discharge nozzle 16a as the third discharge nozzle through the clean water electromagnetic valve 46 and the valve needle 48. Furthermore, the carbonated water sent to the second beverage pouring unit 18 can be poured out from the clean water discharge nozzle 20 a serving as the third discharge nozzle through the clean water electromagnetic valve 50 and the valve needle 52 .

[0021] The beverage machine 10 is provided with a first beverage supply unit 54 for supplying a non-alcoholic beverage as a first beverage. The first beverage supply unit 54 has a first tank 56 containing a non-alcoholic beverage as a first liquid, and is connected to one end of a first rear supply pipe PA4 as a first supply pipe. The first rear supply pipe PA4 is made of polyethylene, for example. In addition, it is not limited to this, and it can also be made of other flexible materials such as synthetic resin. In addition, the first tank 56 is connected to the first jet pump 58 as a first pump. Therefore, the non-alcoholic beverage in the first tank 56 can be pressed toward the main body 12 side through the first rear supply pipe PA4 by using the first jet pump 58. In addition, the first jet pump 58 is connected to the carbon dioxide cylinder 40 through the air pipe PA5. Therefore, carbon dioxide can be dissolved in the non-alcoholic beverage pressed toward the main body 12 side. In addition, although the case where the non-alcoholic beverage is contained in the first tank 56 is described here, it is not limited to this, and an alcoholic beverage can also be contained in the first tank.

[0022] The non-alcoholic beverage delivered to the main body 12 is cooled by the cooling unit 44 and delivered to the first beverage pouring unit 14 or the second beverage pouring unit 18 through the first front supply pipe PA6 as the first supply pipe and the first flow regulating valve 60 as the first adjustment mechanism disposed in the middle thereof. The first front supply pipe PA6 is, for example, made of polyethylene. In addition, it is not limited to this, and can also be made of other flexible materials such as synthetic resin. The non-alcoholic beverage delivered to the first beverage pouring unit 14 can be poured out from the first discharge nozzle 16b through the electromagnetic valve 62 and the valve needle 64. The non-alcoholic beverage delivered to the second beverage pouring unit 18 can be poured out from the first discharge nozzle 20b through the electromagnetic valve 66 and the valve needle 68.

[0023] The beverage machine 10 is also provided with a second beverage supply unit 70 for supplying an alcoholic beverage as a second beverage. The second beverage supply unit 70 has a second tank 72 containing an alcoholic beverage as a second liquid set to a predetermined alcohol concentration, and is connected to one end of a second rear supply pipe PA7 as a second supply pipe. The second rear supply pipe PA7 is, for example, made of polyethylene. In addition, it is not limited to this, and it can also be made of other flexible materials such as synthetic resin. In addition, the second tank 72 is connected to a second jet pump 74 as a second pump. Therefore, the alcoholic beverage in the second tank 72 can be pressed toward the body 12 side through the second rear supply pipe PA7 by using the second jet pump 74. In addition, the second jet pump 74 is connected to the carbon dioxide gas cylinder 40 through the air pipe PA5. Therefore, carbon dioxide can be dissolved in the alcoholic beverage pressed toward the body 12 side. In addition, although the case where the alcoholic beverage is contained in the second tank 72 is described here, it is not limited to this, and non-alcoholic beverage can also be contained in the second tank.

[0024] The alcoholic beverage delivered to the main body 12 is cooled by the cooling unit 44 and delivered to the first beverage pouring unit 14 through the second front supply pipe PA8 as the second supply pipe and the second flow regulating valve 76 as the second adjustment mechanism disposed in the middle thereof. The second front supply pipe PA8 is made of polyethylene, for example. In addition, it is not limited to this and can also be made of other flexible materials such as synthetic resin. The alcoholic beverage delivered to the first beverage pouring unit 14 can be poured out from the second discharge nozzle 16c through the second electromagnetic valve 78 and the valve needle 80.

[0025] A control device 82 is disposed on the lower side of the body 12. The control device 82 is electrically connected to the first jet pump 58 and the second jet pump 74, and is configured to change their discharge amounts. In addition, the control device 82 is electrically connected to the first flow regulating valve 60 and the second flow regulating valve 76, and is configured to make the flow channel expand or shrink by operating them, thereby changing the flow rate of the beverage passing through. Therefore, the control device 82 can adjust the flow rate of the beverage passing through the first flow regulating valve 60 and the second flow regulating valve 76 according to the discharge amount of the first jet pump 58 and the second jet pump 74 in operation. Thus, the concentration of the beverage made by the beverage and carbonated water injected from the nozzle groups 16 and 20 can be accurately adjusted. In addition, a flow meter or a flow sensor can also be set on the first flow regulating valve and the second flow regulating valve, and the control device can be configured to operate the first flow regulating valve and the second flow regulating valve according to the measured value of the flow in the first flow regulating valve and the second flow regulating valve so as to become the expected flow rate.

[0026] In addition, although the case where the flow rate of the beverage passing through the first flow regulating valve 60 and the second flow regulating valve 76 is adjusted according to the discharge volume of the first jet pump 58 and the second jet pump 74 is described here, it is not limited to this. For example, the discharge volume of the first jet pump and the second jet pump may be constant, and the working conditions corresponding to the discharge volume of the beverage of the first flow regulating valve and the second flow regulating valve may be set in advance in the control device, or the expansion or contraction of the flow path of the first flow regulating valve and the second flow regulating valve may be manually set according to the discharge volume of the beverage.

[0027] The control device 82 is electrically connected to the electromagnetic valves 46, 50, 62, 66, 78 installed on the nozzle groups 16 and 20, and sets the opening time of the electromagnetic valves 46, 50, 62, 66, 78 to operate the electromagnetic valves 46, 50, 62, 66, 78. Therefore, the control device 82 can accurately adjust the discharge amount of the beverage and carbonated water discharged from the nozzle groups 16 and 20.

[0028] The control device 82 is also electrically connected to the operating unit 24. Therefore, the discharge amount of the first jet pump 58 and the second jet pump 74, the expansion or contraction of the flow path of the first flow regulating valve 60 and the second flow regulating valve 76, and the opening and closing of the electromagnetic valves 46, 50, 62, 66, and 78 can be controlled according to the discharge amount and the concentration of the beverage input from the operating unit 24.

[0029] A cleaning mechanism 84 for cleaning the first beverage supply unit 54 is provided on the first beverage supply unit 54 for supplying non-alcoholic beverages. The cleaning mechanism 84 is connected to the first rear supply pipe PA4 through an electromagnetic valve 90. When cleaning, the electromagnetic valve 90 can be opened and the jet pump 88 for cleaning can be used to make the clean water in the clean water tank 86 flow to the clean water discharge nozzles 16a and 20a. In this way, the first beverage supply unit 54 for supplying non-alcoholic beverages can be easily cleaned. In addition, although the case where the cleaning mechanism 84 is provided on the first beverage supply unit 54 is described here, it is not limited to this, and the cleaning mechanism can also be provided on the second beverage supply unit. In addition, tap water can also be used instead of the clean water tank 86.

[0030] Figure 3 The operation unit 24 for setting the pouring conditions is shown in the figure. The user can input the concentration of the alcoholic beverage contained in the second tank 72 ("Concentration of original liquid alcohol") and the amount of the beverage to be poured from the nozzle groups 16 and 20 ("Pouring amount" on the touch screen 26). In addition, the concentration of the beverage or the carbonation feeling of the beverage corresponding to the concentration of the beverage when the concentration of the beverage is selected later ("Thin", "Normal", "Slightly Strong", "Strong") on the touch screen 26 can be input and set. In addition, when setting the pouring conditions, the user can switch to the beverage concentration selection screen by pressing "Setting Complete" on the touch screen 26 (refer to Figure 4 ).

[0031] Figure 4 2 shows the operation unit 24 for selecting the concentration of the beverage. The user can select the alcohol concentration of the beverage to be poured from the nozzle groups 16 and 20 (“Select Alcohol” on the touch screen 26) or the concentration or carbonation of the beverage (“Select Concentration” on the touch screen 26). After selecting the concentration, the user can pour the beverage from the nozzle groups 16 and 20 by pressing “Pour” on the touch screen 26.

[0032] Next, the operation and effects of the beverage machine 10 according to the present embodiment will be described below.

[0033] According to the beverage machine 10 involved in this embodiment, the non-alcoholic beverage contained in the first tank 56 is pressure-fed by the first jet pump 58 and is poured out from the first discharge nozzles 16b and 20b of the beverage pouring parts 14 and 18 through the first supply pipes PA4 and PA6. In addition, the alcoholic beverage contained in the second tank 72 is pressure-fed by the second jet pump 74 and is poured out from the second discharge nozzle 16c of the beverage pouring parts 14 and 18 through the second supply pipes PA7 and PA8. In addition, the clean water supplied from the clean water supply part 30 is poured out from the clean water discharge nozzles 16a and 20a of the beverage pouring parts 14 and 18 through the clean water pipes PA1 and PA3. A first flow rate regulating valve 60 is arranged in the middle of the first supply pipes PA4 and PA6, and the flow rate of the non-alcoholic beverage supplied to the first discharge nozzles 16b and 20b can be adjusted. Therefore, the concentration of the non-alcoholic beverage produced by mixing the non-alcoholic beverage poured from the first discharge nozzles 16b and 20b and the clean water poured from the clean water discharge nozzles 16a and 20a can be adjusted. In addition, the second flow control valve 76 is arranged in the middle of the second supply pipes PA7 and PA8, and the flow rate of the alcoholic beverage supplied to the second discharge nozzle 16c can be adjusted. Therefore, the concentration of the alcoholic beverage produced by mixing the alcoholic beverage poured from the second discharge nozzle 16c and the non-alcoholic beverage and clean water poured from the first discharge nozzle 16b and the clean water discharge nozzle 16a can be adjusted. As a result, the alcohol concentration of beverages including non-alcoholic beverages can be accurately customized.

[0034] Furthermore, according to the beverage machine 10 of this embodiment, since non-alcoholic beverages and alcoholic beverages can be respectively discharged from the first discharge nozzles 16b and 20b and the second discharge nozzle 16c, mixing of alcohol can be prevented or suppressed when preparing non-alcoholic beverages.

[0035] In addition, according to the beverage machine 10 involved in this embodiment, the first jet pump 58 can be linked to the first flow control valve 60 by using the control device 82. Therefore, the first flow control valve 60 can be operated according to the amount of non-alcoholic beverage pumped by the first jet pump 58 to adjust the flow rate of the non-alcoholic beverage supplied to the first discharge nozzle 16b, 20b. In addition, the second jet pump 74 can be linked to the second flow control valve 76 by using the control device 82. Therefore, the second flow control valve 76 can be operated according to the amount of alcoholic beverage pumped by the second jet pump 74 to adjust the flow rate of the alcoholic beverage supplied to the second discharge nozzle 16c. As a result, the alcohol concentration of beverages including non-alcoholic beverages can be accurately customized.

[0036] Furthermore, according to the beverage machine 10 involved in this embodiment, the beverage pouring parts 14 and 18 are provided with: the clean water electromagnetic valves 46 and 50 for opening and closing the clean water discharge nozzles 16a and 20a; the first electromagnetic valves 62 and 66 for opening and closing the first discharge nozzles 16b and 20b; and the second electromagnetic valve 78 for opening and closing the second discharge nozzle 16c. The control device 82 is configured to control the time of opening the electrically connected clean water electromagnetic valves 46 and 50, the first electromagnetic valves 62 and 66, and the second electromagnetic valve 78. Therefore, only the correct amount of clean water can be poured from the clean water discharge nozzles 16a and 20a, and only the correct amount of non-alcoholic beverages and alcoholic beverages can be poured from the first discharge nozzles 16b and 20b and the second discharge nozzle 16c. As a result, the alcohol concentration of beverages including non-alcoholic beverages can be accurately customized.

[0037] Furthermore, according to the beverage machine 10 of this embodiment, the alcohol concentration of the beverage poured from the beverage pouring parts 14 and 18 can be set on the operation unit 24 electrically connected to the control device 82. Thus, the alcohol concentration of beverages including non-alcoholic beverages can be accurately customized.

[0038] As described above, the beverage machine 10 according to the present embodiment can accurately customize the concentrations of non-alcoholic beverages and alcoholic beverages.

[0039] In addition, although the case in which the beverage machine 10 is provided with a clean water supply unit 30 as a third liquid supply unit is described herein, the third liquid supply unit is used to supply clean water as the third liquid, but is not limited to this. For example, the third liquid ejected from the third discharge nozzle may also be an alcoholic beverage or a non-alcoholic beverage. For this purpose, a storage tank for containing an alcoholic beverage or a non-alcoholic beverage may also be provided as the third liquid supply unit.

[0040] In addition, although the beverage machine 10 is described here as including the carbon dioxide gas cylinder 40 , the present invention is not limited thereto, and the beverage machine may be configured not to include the carbon dioxide gas cylinder and to dispense only beverages that do not contain carbon dioxide.

[0041] Furthermore, although the case of using the beverage machine 10 to adjust the alcohol concentration including non-alcoholic beverages is described here, it is not limited to this. In addition, the beverage machine can also be configured to adjust the following concentrations as indicators when making beverages, namely: the concentration of the original liquid when the concentrated original liquid is diluted to make the beverage; and the sugar content, salt concentration and pH concentration of the beverage when adjusting the sweetness, saltiness, sourness and aroma.
