The embodiments of the present invention will be described with reference to the drawings.

<1. Outline of beverage manufacturing equipment> FIG. 1 is an external view of the beverage manufacturing device 1. The beverage production apparatus 1 of the present embodiment is an apparatus that automatically produces coffee beverages from roasted coffee beans and liquid (here, water), and can produce a cup of coffee beverage for one production operation. The roasted coffee beans used as a raw material can be contained in a canister 40. In the lower part of the beverage production apparatus 1 is a mounting part 110 provided with a cup, and the coffee beverage to be produced is poured into the cup from the filling part 10c.

The beverage manufacturing apparatus 1 is provided with a housing 100 formed with an outer casing to surround an internal mechanism. The cabinet 100 is roughly divided into a main body 101 and a cover 102 covering a part of the front surface and a part of the side surface of the beverage manufacturing apparatus 1. The cover 102 is provided with an information display device 12. In the case of the present embodiment, the information display device 12 is a touch panel type display, and in addition to displaying various information, it can also accept input from the manager of the device or the drinker. The information display device 12 is attached to the cover 102 via a moving mechanism 12a, and can be moved in a certain range in the vertical direction by the moving mechanism 12a.

The cover 102 is further provided with a bean inlet 103 and a door 103a that opens and closes the bean inlet 103. The opening and closing door 103 can be opened, and roasted coffee beans that are different from the roasted coffee beans stored in the tank 40 can be inserted into the bean insertion opening 103. In this way, a special cup can be provided to the drinker.

In the case of this embodiment, the cover part 102 is formed with a translucent material, such as acrylic (Acryl) or glass, and constitutes the transparent cover whose whole is a transmissive part. Therefore, the mechanism on the inner side covered by the cover 102 can be seen from the outside. In the case of this embodiment, a part of the manufacturing part that manufactures coffee beverages is made visible through the cover part 102. In the case of this embodiment, the main body 101 is a non-transmissive part as a whole, and it is difficult to see the inside from the outside.

FIG. 2 is a partial front view of the beverage manufacturing device 1, a front view of the beverage manufacturing device 1, and a diagram of a part of the manufacturing section that is visible to the user. The cover portion 102 or the information display device 12 is illustrated in imaginary lines.

The cabinet 100 of the front part of the beverage manufacturing apparatus 1 has a dual structure of a main body 101 and a cover 102 on the outside (front side). In the front-rear direction, a mechanism of a part of the manufacturing unit is arranged between the main body 101 and the cover 102, and the user can see through the cover 102.

In the case of the present embodiment, the part of the manufacturing unit that can be viewed by the user through the cover unit 102 is the collective transport unit 42, grinder 5A, 5B, separation device 6, extraction container 9 and the like described later. A rectangular recess 101a recessed to the inside is formed on the front part of the main body 101, and the extraction container 9 and the like are located on the inside of the recess 101a.

These mechanisms can be visually recognized from the outside through the cover part 102, and it may become easier for the manager to check the inspection and the operation. And, for those who need beverages, sometimes they can enjoy the coffee beverage manufacturing process.

In addition, the cover part 102 is supported by the main body part 101 via a hinge 102a at its right end so that it can be opened and closed horizontally. At the left end of the cover portion 102, an engagement portion 102b for maintaining the main body portion 101 and the cover portion 102 in a closed state is provided. The engaging portion 102b is, for example, a combination of magnet and iron. The manager can perform inspections and the like of a part of the above-mentioned manufacturing department inside the cover portion 102 by opening it.

In addition, in the case of the present embodiment, the cover portion 102 is a horizontal opening type, but it may be a vertical opening type (up and down opening type) or a sliding type. Moreover, the cover part 102 may have a structure which cannot be opened and closed.

FIG. 3 is a schematic diagram of the function of the beverage manufacturing apparatus 1. The beverage manufacturing device 1 includes a bean processing device 2 and an extraction device 3 as a coffee beverage manufacturing unit.

The bean processing device 2 produces ground beans from roasted coffee beans. The extraction device 3 extracts coffee liquid from the ground beans supplied from the bean processing device 2. The extraction device 3 includes a fluid supply unit 7, a drive unit 8 described later, an extraction container 9, and a switching unit 10. The ground beans supplied from the bean processing device 2 are put into the extraction container 9. The fluid supply unit 7 puts hot water into the extraction container 9. The coffee liquid is extracted from the ground beans in the extraction container 9. The hot water containing the drawn coffee liquid is delivered to the cup C as a coffee beverage via the switching unit 10.

<2. Fluid supply unit and switching unit> The configuration of the fluid supply unit 7 and the switching unit 10 will be described with reference to FIG. 3. First, the fluid supply unit 7 will be described. The fluid supply unit 7 performs the supply of hot water to the extraction container 9 or the control of the air pressure in the extraction container 9. In addition, in this specification, when the air pressure is exemplified by numbers, unless specifically explained otherwise, it means absolute pressure, and the so-called gauge pressure is the air pressure with the atmospheric pressure set to 0 atmospheric pressure. The so-called atmospheric pressure means to extract the air pressure around the container 9 or the air pressure of the beverage manufacturing device. For example, when the beverage manufacturing device is installed at an altitude of 0 m, the international civil aviation organization (= "International Civil Aviation Organization" (referred to as ICAO)) The reference air pressure (1013.25hPa) at an altitude of 0m in the International Standard Atmosphere (= "International Standard Atmosphere" (ISA)) established in 1976.

The fluid supply unit 7 includes pipes L1 to L3. The pipe L1 is a pipe through which air flows, and the pipe L2 is a pipe through which water flows. The pipe L3 is a pipe through which both air and water can circulate.

The fluid supply unit 7 includes a compressor 70 as a pressure source. The compressor 70 compresses the atmosphere and sends it out. The compressor 70 is driven by a motor (not shown) as a driving source, for example. The compressed air sent from the compressor 70 is supplied to the air tank (air tank) 71 via the check valve 71a. The air pressure in the air tank 71 is monitored by the pressure sensor 71b, and the compressor 70 is driven to maintain a predetermined air pressure (in this embodiment, 7 air pressure (gauge pressure, 6 air pressure)). The air storage tank 71 is provided with a drain 71c for drainage, which can drain water generated by the compression of air.

Hot water (water) constituting the coffee beverage is stored in the water tank 72. The water tank 72 is provided with a heater 72a for heating the water in the water tank 72 and a temperature sensor 72b for measuring the temperature of the water. The heater 72a maintains the temperature of the accumulated hot water at a predetermined temperature (120 degrees Celsius in this embodiment) based on the detection result of the temperature sensor 72b. For the heater 72a, for example, the temperature of hot water is turned on at 118 degrees Celsius and is turned off at 120 degrees Celsius.

The water tank 72 is also provided with a water level sensor 72c. The water level sensor 72c detects the water level of the hot water in the water tank 72. Once the water level sensor 72c detects that the water level is lower than the predetermined water level, the water is supplied to the water tank 72. In the case of this embodiment, tap water is supplied via a water purifier not shown. A solenoid valve 72d is provided on the way from the piping L2 of the water purifier. Once the water level sensor 72c detects a drop in the water level, the solenoid valve 72d is opened to supply water. Once the water level reaches a predetermined level, The solenoid valve 72d is blocked to block the water supply. In this way, the hot water in the water tank 72 will be maintained at a certain water level. In addition, the water supply to the water tank 72 may be performed every time the hot water used for the production of a coffee beverage is discharged.

The water tank 72 is further provided with a pressure sensor 72g. The pressure sensor 72g detects the air pressure in the water tank 72. In the water tank 72, the air pressure in the air tank 71 is supplied via the pressure regulating valve 72e and the solenoid valve 72f. The pressure regulating valve 72e depressurizes the air pressure supplied from the gas tank 71 to a predetermined air pressure. In the case of this embodiment, the pressure is reduced to 3 atmospheres (gauge pressure, 2 atmospheres). The solenoid valve 72f switches the supply and shutoff of the air pressure regulated by the pressure regulating valve 72e to the water tank 72. Except for the supply of tap water to the water tank 72, the solenoid valve 72f is opened and closed so that the air pressure in the water tank 72 is maintained at 3 atmospheric pressure. When the tap water is supplied to the water tank 72, the air pressure in the water tank 72 is reduced by the solenoid valve 72h to a pressure lower than the water pressure of the tap water (for example, less than 2.5 air pressure), and the water pressure of the tap water Come and supply tap water to the sink 72 smoothly. The solenoid valve 72h switches whether to release the inside of the water tank 72 to the atmosphere, and releases the inside of the water tank 72 to the atmosphere at the time of pressure reduction. In addition, the solenoid valve 72h releases the inside of the water tank 72 to the atmosphere when the air pressure in the water tank 72 exceeds 3 air pressure, and maintains the inside of the water tank 72 at 3 air pressure, except when the tap water is supplied to the water tank 72.

The hot water in the water tank 72 is supplied to the extraction container 9 via the check valve 72j, the solenoid valve 72i, and the pipe L3. The solenoid valve 72i is opened to supply hot water to the extraction container 9, and the supply of hot water is blocked by closing. The amount of hot water supplied to the extraction container 9 can be managed by the opening time of the solenoid valve 72i. However, the supply amount may be measured to control the opening and closing of the solenoid valve 72i. The pipe L3 is provided with a temperature sensor 73e that measures the temperature of the hot water, and monitors the temperature of the hot water supplied to the extraction container 9.

The air pressure of the air tank 71 is also supplied to the extraction container 9 via the pressure regulating valve 73a and the solenoid valve 73b. The pressure regulating valve 73a reduces the pressure of the air pressure supplied from the air tank 71 to a predetermined air pressure. In the case of this embodiment, the pressure is reduced to 5 atmospheres (gauge pressure, 4 atmospheres). The solenoid valve 73b switches the supply and shutoff of the air pressure regulated by the pressure regulating valve 73a to the extraction container 9. The air pressure in the extraction container 9 is detected by the pressure sensor 73d. When the pressure in the extraction container 9 is pressurized, the solenoid valve 73b is opened based on the detection result of the pressure sensor 73d to pressurize the interior of the extraction container 9 to a predetermined air pressure (in the case of this embodiment, the maximum 5 air pressure (gauge pressure, 4 air pressure)). The air pressure in the extraction container 9 can be reduced by the solenoid valve 73c. The solenoid valve 73c switches whether to release the inside of the extraction container 9 to the atmosphere. When the pressure is abnormal (for example, when the inside of the extraction container 9 exceeds 5 atmospheric pressure), the inside of the extraction container 9 is released to the atmosphere.

When the manufacture of the coffee beverage once is finished, in the case of this embodiment, the inside of the extraction container 9 is washed with tap water. The solenoid valve 73f is opened during washing and supplies tap water to the extraction container 9.

Next, the switching unit 10 will be explained. The switching unit 10 is a unit that switches the delivery point of the liquid delivered from the extraction container 9 to either the injection portion 10c or the waste gas tank T. The switching unit 10 includes a switching valve 10a and a motor 10b that drives the switching valve 10a. The switching valve 10a switches the flow path to the injection part 10c when the coffee beverage in the extracted container 9 is delivered. The coffee beverage is poured into the cup C from the filling part 10c. When the waste liquid (tap water) and residue (bean grinding) during washing are discharged, the flow path is switched to the waste gas tank T. In the case of this embodiment, the switching valve 10a is a three-port ball valve. During washing, since the residue will pass through the switching valve 10a, it is appropriate that the switching valve 10a is a ball valve, and the flow path is switched by rotating the rotating shaft of the motor 10b.

＜3. Bean processing device＞ The bean processing device 2 will be described with reference to FIGS. 1 and 2. The bean processing device 2 includes a storage device 4 and a crushing device 5.

＜3-1. Storage device＞ The storage device 4 includes a plurality of tanks 40 for storing roasted coffee beans. In the case of this embodiment, three tanks 40 are provided. The tank 40 includes a cylindrical main body 40a for storing roasted coffee beans, and a handle 40b provided on the main body 40a, and is configured to be detachably attachable to the beverage manufacturing apparatus 1.

Each tank 40 can also contain different types of roasted coffee beans, and the type of roasted coffee beans used in the production of coffee beverages can be selected by operating input to the information display device 12. Roasted coffee beans of different kinds are, for example, roasted coffee beans of different kinds of coffee beans. In addition, the so-called roasted coffee beans of different types are roasted coffee beans of the same type but different roasting degrees. In addition, the so-called roasted coffee beans of different types may also be roasted coffee beans of different varieties and roasting degrees. In addition, at least any one of the three tanks 40 may contain roasted coffee beans in which multiple types of roasted coffee beans are mixed. In this case, the roasting degree of roasted coffee beans of different varieties can also be the same.

In addition, in this embodiment, plural tanks 40 are provided, but a single tank 40 may be provided. In addition, when a plurality of tanks 40 are installed, roasted coffee beans of the same kind may be contained in all or a plurality of tanks 40.

Each tank 40 is detachably attached to the weighing conveying device 41. The weighing conveyor 41 is, for example, an electric screw conveyor, and automatically weighs a predetermined amount of roasted coffee beans stored in the tank 40 and sends it to the downstream side.

Each metering conveying device 41 is a collective conveying unit 42 that discharges roasted coffee beans to the downstream side. The collective conveyance part 42 is constituted by a hollow member, and forms a conveyance path for roasted coffee beans from each conveyor 41 to the grinding device 5 (especially the grinder 5A). The roasted coffee beans discharged from each weighing and conveying device 41 move inside the collecting and conveying portion 42 by their own weight, and flow to the crushing device 5.

The collective conveyance part 42 has a guide part 42 a formed at a position corresponding to the bean insertion port 103. The guide portion 42a forms a passage for guiding the roasted coffee beans thrown in from the bean feeding port 103 to the grinding device 5 (especially the grinder 5A). Thereby, in addition to the roasted coffee beans accommodated in the tank 40, a coffee beverage using the roasted coffee beans injected from the bean injection port 103 as a raw material can also be manufactured.

＜3-2. Crushing device＞ The crushing device 5 will be described with reference to FIGS. 2 and 4. FIG. 4 is a broken perspective view of a part of the separation device 6. The pulverizing device 5 includes grinders 5A and 5B and a separating device 6. The grinders 5A and 5B are mechanisms for grinding roasted coffee beans supplied from the storage device 4. The roasted coffee beans supplied from the storage device 4 are ground by the grinder 5A, and then further ground by the grinder 5B to form a powder, and are introduced into the extraction container 9 from the discharge pipe 5C.

The grinders 5A and 5B have different particle sizes for grinding beans. The grinder 5A is a grinder for rough grinding, and the grinder 5B is a grinder for fine grinding. The grinders 5A and 5B are electric grinders, respectively, and include a drive source motor, and a rotating blade driven by the motor. By changing the number of rotations of the rotating blade, the size (particle size) of the roasted coffee beans to be ground can be changed.

The separating device 6 is a mechanism for separating unnecessary objects from the ground beans. The separation device 6 includes a passage portion 63a arranged between the grinder 5A and the grinder 5B. The passage portion 63a is a hollow body that forms a separation chamber through which ground beans freely falling from the grinder 5A can pass. The passage portion 63a is connected to a passage portion 63b extending in a direction (in the case of this embodiment, the left and right direction) crossing the passing direction of the ground beans (in the case of this embodiment, the vertical direction), and this passage portion 63b is connected to the suction unit 60 . By sucking the air in the passage portion 63a by the suction unit 60, it is possible to suck light objects such as thin skin or fine powder. By this, unnecessary objects can be separated from the ground beans.

The suction unit 60 is a centrifugal separation mechanism. The suction unit 60 includes a blower unit 60A and a recovery container 60B. In the case of this embodiment, the air blowing unit 60A is a fan motor, and exhausts the air in the recovery container 60B upward.

The recovery container 60B includes an upper part 61 and a lower part 62 that are detachably engaged. The lower part 62 is formed in a cylindrical shape with a bottom open at the top, and forms a space for storing unnecessary objects. The upper part 61 is a cover part that constitutes an opening attached to the lower part 62. The upper part 61 includes a cylindrical outer peripheral wall 61a and an exhaust tube 61b formed coaxially. The air blowing unit 60A sucks the air in the exhaust tube 61b, and is fixed to the upper part 61 above the exhaust tube 61b. The upper part 61 is a connecting passage part 63b. The passage portion 63b is opened to the side of the exhaust cylinder 61b.

Driven by the air supply unit 60A, the airflow shown by arrows d1 to d3 in FIG. 4 is generated. With this airflow, the air containing unnecessary objects is sucked into the recovery container 60B from the passage portion 63a through the passage portion 63b. Since the passage portion 63b is opened to the side of the exhaust tube 61b, the air containing unnecessary objects swirls around the exhaust tube 61b. The unnecessary objects D in the air fall by their weight, and are collected in a part of the recovery container 60B (accumulated on the bottom surface of the lower portion 62). The air is exhausted upward through the inside of the exhaust cylinder 61b.

Plural fins 61d are integrally formed on the peripheral surface of the exhaust pipe 61b. The plural fins 61d are arranged in the circumferential direction of the exhaust pipe 61b. Each fin 61d is inclined obliquely with respect to the axial direction of the exhaust pipe 61b. By providing such a fin 61, the swirling around the exhaust pipe 61b of the air containing the unnecessary substance D is promoted.

In the case of this embodiment, the lower part 62 is formed of a transparent material such as acrylic or glass, and constitutes a transparent container whose entirety is a transmissive part. Moreover, the lower part 62 is a part covered by the cover part 102 (FIG. 2). A manager or a drinker can see the unnecessary objects D accumulated in the lower part 62 through the peripheral wall of the cover part 102 and the lower part 62. For managers, it is sometimes easy to confirm the timing of cleaning the lower part 62. For drinkers, by observing that the unnecessary objects D are removed, the sense of expectation for the quality of the coffee beverage being manufactured may increase. .

In this way, in this embodiment, the roasted coffee beans supplied from the storage device 4 are first coarsely ground by the grinder 5A, and when the coarsely ground beans pass through the passage portion 63a, the separation device 6 separates unnecessary objects. The coarsely ground beans from which unwanted objects are separated are finely ground by the grinder 5B. The unnecessary objects separated by the separating device 6 are represented by thin skin or fine powder. This sometimes reduces the taste of coffee beverages, and the quality of coffee beverages can be improved by removing thin skin from the ground beans.

The grinding of roasted coffee beans can also be a grinder (one-stage grinding). However, as in the present embodiment, the two-stage grinding by the two grinders 5A and 5B makes the grain size of the ground beans easy to be uniform, and the degree of extraction of the coffee liquid can be made constant. When the beans are crushed, heat is sometimes generated by friction between the cutter and the beans. With the two-stage pulverization, heat generation caused by friction during pulverization can also be suppressed, and deterioration of the ground beans (such as reduced flavor) can be prevented.

In addition, by going through the stages of coarse grinding → separation of unnecessary objects → fine grinding, when separating unnecessary objects such as thin skins, the quality of the unnecessary objects and the ground beans (necessary parts) can be enlarged. This can improve the separation efficiency of unnecessary objects and prevent the ground beans (necessary parts) from being separated as unnecessary objects. In addition, by intervening the separation process of unnecessary objects by air suction between the coarse grinding and the fine grinding, the heat generation of the ground beans can be suppressed by air cooling.

＜4. Drive unit and extraction container＞ ＜4-1. Summary＞ With reference to FIG. 5, the drive unit 8 and the withdrawal container 9 of the withdrawal device 3 will be described. FIG. 5 is a perspective view of the drive unit 8 and the withdrawal container 9. Most of the drive unit 8 is surrounded by the main body 101.

The drive unit 8 is supported by the frame F. The frame F is a column part F3 including upper and lower beam parts F1 and F2 and supporting beam parts F1 and F2. The drive unit 8 is roughly divided into three units that are divided into an upper unit 8A, a middle unit 8B, and a lower unit 8C. The upper unit 8A is supported by the beam F1. The middle unit 8B is between the beam F1 and the beam F2, and is supported by the beam F1 and the column F3. The lower unit 8C is supported by the beam F2.

The extraction container 9 is a chamber including a container body 90 and a lid unit 91. The withdrawal container 9 is sometimes called a chamber. The middle unit 8B is provided with an arm member 820 that detachably holds the container body 90. The arm member 820 includes a holding member 820a and a pair of left and right shaft members 820b. The holding member 820a is an elastic member formed of a C-shaped clip-like resin or the like, and holds the container body 90 by its elastic force. The holding member 82a holds the left and right side portions of the container body 90, and the front side of the container body 90 is exposed. Thereby, the inside of the container body 90 can be easily seen from the front.

The attachment and detachment of the container body 90 to the holding member 820a is performed manually. By pushing the container body 90 to the holding member 820a backward in the front-rear direction, the container body 90 is attached to the holding member 820a. In addition, the container body 90 can be separated from the holding member 820a by pulling out the container body 90 from the front-rear direction of the holding member 820a toward the front side.

The pair of shaft members 820b are rods each extending in the front-rear direction and supporting the holding member 820a. In addition, in the present embodiment, the number of shaft members 820b is two, but it may be one, or three or more. The holding member 820a is fixed to the front end of the pair of shaft members 820b. With the mechanism described later, the pair of shaft members 82b advance and retreat in the front-rear direction, so that the holding member 820a advances and retreats, and the container body 90 can be moved in parallel in the front-rear direction. The middle unit 8B is also capable of performing a rotation operation that reverses the up and down of the withdrawn container 9 as described later.

＜4-2. Withdraw the container＞ The withdrawal container 9 will be explained with reference to FIG. 6. FIG. 6 is a diagram showing the closed state and the open state of the extraction container 9. As described above, the withdrawal container 9 is reversed up and down by the middle unit 8B. The withdrawal container 9 of FIG. 6 shows the basic posture in which the lid unit 91 is located on the upper side. In the following description, when the positional relationship of the top and bottom is described, unless otherwise explained, it means the positional relationship of the top and bottom of the basic posture.

The container body 90 is a bottomed container, and has a bottle shape having a neck portion 90b, a shoulder portion 90d, a waist portion 90e, and a bottom portion 90f. At the end of the neck portion 90b (the upper end of the container body 90), a flange portion 90c defining an opening 90a communicating with the internal space of the container body 90 is formed.

Both the neck 90b and the waist 90e have a cylindrical shape. The shoulder portion 90d is a portion between the neck portion 90b and the waist portion 90e, and has a tapered shape so that the cross-sectional area of the internal space gradually decreases from the waist portion 90e side toward the neck portion 90b side.

The cover unit 91 is a unit that opens and closes the opening 90a. The opening and closing operation (lifting operation) of the cover unit 91 is performed by the upper unit 8A.

The container body 90 includes a body member 900 and a bottom member 901. The main body member 900 is a cylindrical member in which the upper and lower sides forming the neck portion 90b, the shoulder portion 90d, and the waist portion 90e are open. The bottom member 901 is a member that forms the bottom 90f, and is inserted into the lower portion of the main body member 900 and fixed. A sealing member 902 is interposed between the body member 900 and the bottom member 901 to improve the airtightness of the container body 90.

In the case of the present embodiment, the main body member 900 is formed of a translucent material such as acrylic or glass, and constitutes a transparent container whose entirety is a transmissive portion. The manager or the person who needs the drink can see the extraction status of the coffee beverage in the container body 90 through the cover portion 102 and the body member 900 of the container body 90. For managers, it is sometimes easy to confirm the withdrawal action, and for drinkers, sometimes they can enjoy the withdrawal situation.

A convex portion 901c is provided at the center of the bottom member 901. The convex portion 901c is provided with a communication hole for communicating the inside of the container body 90 to the outside and a valve for opening and closing the communication hole (valve 903 in FIG. 8). The communication hole is used to discharge waste liquid and residue when used in the cleaning container body 90. The convex portion 901c is provided with a sealing member 908, and the sealing member 908 is a member for maintaining the airtightness between the upper unit 8A or the lower unit 8C and the bottom member 901.

The cover unit 91 is provided with a hat-shaped base member 911. The base member 911 has a convex portion 911d and a brim portion 911c overlapping the flange portion 90c when closed. The convex portion 911d has the same structure as the convex portion 901c of the container body 90, and is provided with a communication hole for communicating the inside of the container body 90 to the outside, and a valve for opening and closing the communication hole (valve 913 in FIG. 8). The communication hole of the convex portion 911d is mainly used for the injection of hot water into the container body 90 and the delivery of coffee beverages. The convex part 911d is provided with the sealing member 918a. The sealing member 918a is a member for maintaining airtightness between the upper unit 8A or the lower unit 8C and the base member 911. The cover unit 91 is further provided with a sealing member 919. The sealing member 919 improves the airtightness between the lid unit 91 and the container body 90 when the lid unit 91 is closed. The cover unit 91 holds a filter for filtering.

＜4-3. Upper unit and lower unit＞ The upper unit 8A and the lower unit 8C will be described with reference to Figs. 7 and 8. FIG. 7 is a front view showing the configuration of a part of the upper unit 8A and the lower unit 8C, and FIG. 8 is a vertical sectional view of FIG. 7.

The upper unit 8A includes an operating unit 81A. The operation unit 81A performs opening and closing operations (lifting and lowering) of the container body 90 by the lid unit 91 and opening and closing operations of the valves of the convex portions 901c and 911d. The operation unit 81A includes a supporting member 800, a holding member 801, a lifting shaft 802, and a probe 803.

The supporting member 800 is fixedly installed in such a manner that the relative position to the frame F does not change, and the holding member 801 is accommodated. The support member 800 is further provided with a communication portion 800 a that allows the pipe L3 to communicate with the inside of the support member 800. The hot water, tap water, and air pressure supplied from the pipe L3 are introduced into the support member 800 via the communication portion 800a.

The holding member 801 is a member that detachably holds the cover unit 91. The holding member 801 is a cylindrical space having a convex portion 911d inserted into the cover unit 91 or a convex portion 901c of the bottom member 901, and has a mechanism for detachably holding these. This mechanism is, for example, a snap ring mechanism, which is engaged by a certain pushing force and released by a certain separation force. The hot water, tap water, and air pressure supplied from the pipe L3 can be supplied into the extraction container 9 via the communication portion 800a and the communication hole 801a of the holding member 801.

The holding member 801 is also a movable member that is slidably provided in the support member 800 in the vertical direction. The lift shaft 802 is installed so that its axial direction becomes the up-down direction. The elevating shaft 802 penetrates the top of the support member 800 airtightly in the vertical direction, and is provided for the support member 800 to be up and down freely.

At the lower end of the lifting shaft 802 is the top of the fixed holding member 801. The holding member 801 is slid in the up-down direction by the lifting shaft 802, so that the holding member 801 can be attached to and separated from the convex portion 911d or the convex portion 901c. In addition, the lid unit 91 can open and close the container body 90.

On the outer peripheral surface of the lift shaft 802, a bolt 802a constituting a lead screw mechanism is formed. Here, the bolt 802a is screwed into the nut 804b. The upper unit 8A is equipped with a motor 804a, and the nut 804b is rotated at the moment (not moved up and down) by the driving force of the motor 804a. The lifting shaft 802 is lifted and lowered by the rotation of the nut 804b.

The lift shaft 802 is a tubular shaft having a through hole in the center axis, and the probe 803 is inserted into the through hole slidably up and down. The probe 803 penetrates the top of the holding member 801 airtightly in the up-down direction, and is provided so as to be up and down for the supporting member 800 and the holding member 801.

The probe 803 is an operating element that opens and closes the valves 913, 903 provided inside the convex portions 911d, 901c. The valves 913, 903 can be moved from the closed state to the open state by the lowering of the probe 803. The rise of 803 changes the valve from the open state to the closed state (by the action of a return spring not shown).

On the outer peripheral surface of the probe 803, a bolt 803a constituting a lead screw mechanism is formed. Here, the bolt 803a is screwed into the nut 805b. The upper unit 8A is equipped with a motor 805a, and the nut 805b is set to rotate at the moment (not moving up and down) by the driving force of the motor 805a. The probe 803 is raised and lowered by the rotation of the nut 805b.

The lower unit 8C includes an operating unit 81C. The operating unit 81C has a configuration in which the operating unit 81A is reversed up and down, and performs opening and closing operations of the valves 913 and 903 provided inside the convex portions 911d and 901c. The operation unit 81C is also a structure capable of opening and closing the lid unit 91, but in this embodiment, the operation unit 81C is not used for opening and closing the lid unit 91.

Hereinafter, although it is substantially the same as the description of the operation unit 81A, the operation unit 81C will be described. The operation unit 81C includes a supporting member 810, a holding member 811, an elevating shaft 812, and a probe 813.

The supporting member 810 is fixedly installed in such a manner that the relative position with respect to the frame F does not change, and houses the holding member 811. The supporting member 810 is further provided with a communication portion 810a for communicating the switching valve 10a of the switching unit 10 with the inside of the supporting member 810. Residues of coffee beverages, tap water, and ground beans in the container body 90 are introduced to the switching valve 10a through the communication portion 810a.

The holding member 811 is a cylindrical space having the convex portion 911d inserted into the cover unit 91 or the convex portion 901c of the bottom member 901, and has a mechanism for detachably holding these. This mechanism is, for example, an engagement mechanism, which engages with a certain pushing force and releases the engagement with a certain separation force. The coffee beverage, tap water, and ground bean residues in the container body 90 are introduced to the switching valve 10a through the communicating portion 810a and the communicating hole 811a of the holding member 811.

The holding member 811 is also a movable member that is slidably provided in the support member 810 in the vertical direction. The lifting shaft 812 is provided so that its axial direction becomes the up-down direction. The elevating shaft 812 penetrates the bottom of the support member 800 airtightly in the up-and-down direction, and is provided for the support member 810 to be up and down freely.

At the lower end of the lifting shaft 812 is the bottom of the fixed holding member 811. The holding member 811 slides in the up and down direction by the lifting shaft 812, so that the holding member 811 can be attached to and separated from the convex portion 901c or the convex portion 911d.

A bolt 812a constituting a lead screw mechanism is formed on the outer peripheral surface of the lifting shaft 812. Here, the bolt 812a is screwed into the nut 814b. The lower unit 8C is equipped with a motor 814a, and the nut 814b is rotated at the moment (not moved up and down) by the driving force of the motor 814a. The lifting shaft 812 is lifted and lowered by the rotation of the nut 814b.

The lift shaft 812 is a tubular shaft having a through hole in the center axis, and the probe 813 is inserted into the through hole slidably up and down. The probe 813 penetrates through the bottom of the holding member 811 in an up-down direction airtightly, and is provided so that the support member 810 and the holding member 811 can be vertically raised and lowered.

The probe 813 is an operating element that opens and closes the valves 913, 903 provided inside the convex portions 911d, 901c. The probe 813 can be moved up to change the valves 913, 903 from the closed state to the open state. The lowering of the valve changes the valve from the open state to the closed state (by the action of the return spring not shown).

On the outer peripheral surface of the probe 813, a bolt 813a constituting a lead screw mechanism is formed. Here, the bolt 813a is screwed into the nut 815b. The lower unit 8C is equipped with a motor 815a, and the nut 815b is set to rotate at the moment (not moving up and down) by the driving force of the motor 815a. The probe 813 is raised and lowered by the rotation of the nut 815b.

＜4-4. Central unit＞ The central unit 8B will be described with reference to FIGS. 5 and 9. Fig. 9 is a schematic diagram of the middle unit 8B. The middle unit 8B includes a support unit 81B that supports the withdrawal container 9. The support unit 81B includes a unit body 81B' that supports the lock mechanism 821 in addition to the aforementioned arm member 820.

The lock mechanism 821 is a mechanism that maintains the lid unit 91 in a closed state with respect to the container body 90. The locking mechanism 821 is a gripping member 821a including a pair of the brim portion 911c of the lid unit 91 and the flange portion 90c of the container body 90 up and down. The pair of gripping members 821a have a C-shaped cross section in which the brim portion 911c and the flange portion 90c are sandwiched and fitted, and are opened and closed in the left-right direction by the driving force of the motor 822. When the pair of gripping members 821a are in the closed state, as shown by solid lines in the circled diagram of FIG. 9, each gripping member 821a is fitted into the brim portion 911c and the flange portion 90c by sandwiching the brim portion 911c and the flange portion 90c up and down. Etc., the lid unit 91 is airtightly locked to the container body 90. In this locked state, even if the holding member 801 is lifted by the lift shaft 802 to open the cover unit 91, the cover unit 91 does not move (the lock is not released). That is, the force of locking by the locking mechanism 821 is set to be stronger than the force of using the holding member 801 to open the cover unit 91. Thereby, it is possible to prevent the lid unit 91 from being opened to the container body 90 when abnormal.

Also, when the pair of gripping members 821a are in the open state, as shown by the dotted line in the circled diagram of FIG. 9, each gripping member 821a will be in a state separated from the brim portion 911c and the flange portion 90c, and the cover unit 91 and The lock of the container body 90 is released.

When the holding member 801 is in the state of holding the lid unit 91 and the holding member 801 is raised from the lowered position to the raised position, the lid unit 91 will be separated from the container body 90 when the pair of holding members 821a are in the open state. Conversely, when the pair of holding members 821a are in the closed state, the holding member 801 for the cover unit 91 is released, and only the holding member 801 rises.

The middle unit 8B further includes a mechanism that uses the motor 823 as a drive source to horizontally move the arm member 820 in the front-rear direction. Thereby, the container body 90 supported by the arm member 820 can be moved between the extraction position (state ST1) on the rear side and the bean insertion position (state ST2) on the front side. The bean input position is a position where the ground beans are injected into the container body 90, and the ground beans ground by the grinder 5B are injected from the discharge pipe 5C to the opening 90a of the container body 90 from which the lid unit 91 is separated. In other words, the position of the discharge pipe 5C is above the container body 90 at the bean input position.

The extraction position is a position where the container body 90 can be operated by the operating unit 81A and the operating unit 81C, and is a position coaxial with the probes 803 and 813, where the coffee liquid is extracted. The extraction position is a position on the inner side than the bean insertion position. Figures 5, 7 and 8 all show the case where the container body 90 is in the withdrawn position. With the introduction of the ground beans, the extraction of coffee liquid, and the supply of water, the position of the container body 90 is different, and the heat generated when the coffee liquid is extracted can be prevented from adhering to the discharge pipe 5C of the supply part of the ground coffee.

The middle unit 8B further includes a mechanism that uses the motor 824 as a drive source to rotate the support unit 81B around an axis 825 in the front-rear direction. Thereby, the posture of the container body 90 (withdrawing the container 9) can be changed from the upright posture (state ST1) where the neck 90b is on the upper side to the inverted posture (state ST3) where the neck 90b is on the lower side. During the rotation of the extracted container 9, the state in which the lid unit 91 is locked to the container body 90 by the locking mechanism 821 is maintained. In the upright posture and the inverted posture, the container 9 is drawn up and down to be reversed. In the inverted posture, the convex portion 911d is positioned at the convex portion 901c in the upright posture. In addition, in the inverted posture, the convex portion 901c is positioned at the convex portion 911d in the upright posture. Therefore, in the inverted posture, the operating unit 81A can perform opening and closing operations on the valve 903, and the operating unit 81C can perform opening and closing operations on the valve 913.

＜5. Control device＞ The control device 11 of the beverage manufacturing device 1 will be described with reference to FIG. 10. FIG. 10 is a block diagram of the control device 11.

The control device 11 controls the entire beverage manufacturing device 1. The control device 11 includes a processing unit 11a, a storage unit 11b, and an I/F (interface) unit 11c. The processing unit 11a is a processor such as a CPU. The storage unit 11b is, for example, RAM or ROM. The I/F unit 11c is an input/output interface for input/output of signals between the external device and the processing unit 11a. The I/F unit 11c further includes a communication interface that can communicate data with the server 16 via a communication network 15 such as the Internet. The server 16 can communicate with a portable terminal device 17 such as a smartphone via the communication network 15. For example, it can receive information such as a beverage making reservation or thoughts from the portable terminal device 17 of a beverage user.

The processing unit 11a executes a program stored in the memory unit 11b, and controls the actuator group 14 based on an instruction from the information display device 12, a detection result of the sensor group 13, or an instruction from the server 16. The sensor group 13 is various sensors provided in the beverage manufacturing apparatus 1 (for example, a temperature sensor for hot water, an operation position detection sensor for a mechanism, a pressure sensor, etc.). The actuator group 14 is various actuators (for example, motors, solenoid valves, heaters, etc.) provided in the beverage manufacturing apparatus 1.

＜6. Example of action control＞ An example of the control processing of the beverage manufacturing apparatus 1 executed by the processing unit 11a will be described with reference to FIGS. 11A (A) and (B). Fig. 11(A) shows an example of control related to one coffee beverage production operation. The state of the beverage manufacturing apparatus 1 before the manufacturing instruction is referred to as a standby state. The state of each mechanism in the standby state is as follows.

The extraction device 3 is in the state of FIG. 5. The withdrawal container 9 is in an upright posture and is located at the withdrawal position. The lock mechanism 821 is in the closed state, and the lid unit 91 closes the opening 90 a of the container body 90. The holding member 801 is in the lowered position, and is attached to the convex portion 911d. The holding member 811 is in a raised position, and is attached to the convex part 901c. The valves 903 and 913 are in the closed state. The switching valve 10a connects the communication portion 810a of the operation unit 8C with the exhaust gas tank T.

In the standby state, if there is an instruction to manufacture a coffee beverage, the process of FIG. 11(A) is executed. In S1, pre-heat treatment is carried out. This process is a process of pouring hot water into the container body 90 and heating the container body 90 in advance. First, the valves 903 and 913 are set to the open state. Thereby, the pipe L3, the extraction container 9, and the waste gas tank T will be in a communicating state.

The solenoid valve 72i is opened only for a predetermined time (for example, 1500 ms) and then closed. Thereby, hot water is injected from the water tank 72 into the extraction container 9. Next, the solenoid valve 73 is opened for a predetermined time (for example, 500 ms) and then closed. Thereby, the air in the extraction container 9 is pressurized, and the discharge of hot water to the waste gas tank T is promoted. Through the above processing, the inside of the extraction container 9 and the pipe L2 will be preheated, and then in the production of coffee beverages, the hot water can be reduced to become cold.

In S2, a grinding process is performed, where the roasted coffee beans are ground, and the ground beans are put into the container body 90. First, the lock mechanism 821 is set to the open state, and the holding member 801 is raised to the raised position. The cover unit 91 is held by the holding member 801 and rises together with the holding member 801. As a result, the lid unit 91 is separated from the container body 90. The holding member 811 is lowered to the lowered position. The container body 90 is moved to the bean insertion position. Next, the storage device 4 and the crushing device 5 are operated. Thereby, a cup of roasted coffee beans is supplied from the storage device 4 to the grinder 5A. In the grinders 5A and 5B, the roasted coffee beans are ground in two stages, and the separating device 6 separates unwanted objects. The ground beans are put into the container body 90.

Return the container body 90 to the withdrawn position. The holding member 801 is lowered to the lowered position, and the lid unit 91 is attached to the container body 90. The lock mechanism 821 is set to the closed state, and the lid unit 91 is airtightly locked to the container body 90. The holding member 811 is raised to the raised position. Among the valves 903 and 913, the valve 903 is in the open state, and the valve 913 is in the closed state.

In S3, extraction processing is performed. Here, the coffee liquid is drawn from the ground beans in the container body 90. FIG. 11(B) is a flowchart of the extraction process of S3.

In S11, in order to steam the ground beans in the extraction container 9, the hot water in an amount less than a cup of hot water is injected into the extraction container 9. Here, the solenoid valve 72i is opened and closed for a predetermined time (for example, 500 ms). Thereby, hot water is injected from the water tank 72 into the extraction container 9. Then, it waits for a predetermined time (for example, 5000 ms) and ends the processing of S11. This can be used to steam and grind beans. By steaming and grinding the beans, the carbon dioxide contained in the beans can be released, which improves the extraction effect afterwards.

In S12, the remaining amount of hot water is poured into the extraction container 9 so that a cup of hot water is contained in the extraction container 9. Here, the solenoid valve 72i is opened and closed for a predetermined time (for example, 7000 ms). Thereby, hot water is injected from the water tank 72 into the extraction container 9.

By the process of S12, the inside of the extraction container 9 can be in a state where 1 atmospheric pressure exceeds 100 degrees Celsius (for example, about 110 degrees Celsius). Next, in S13, the inside of the extraction container 9 is pressurized. Here, the solenoid valve 73b is opened and closed for a predetermined time (for example, 1000 ms), and the inside of the extraction container 9 is pressurized to an air pressure at which hot water does not boil (for example, about 4 atmospheric pressure (gauge pressure, about 3 atmospheric pressure)). Then, the valve 903 is set to the closed state.

Next, this state is maintained for a predetermined time (for example, 7000 ms), and the immersion coffee liquid is drawn (S14). In this way, the immersion coffee liquid is extracted under high temperature and high pressure. The immersion-type extraction under high temperature and high pressure is expected to have the following effects. First, by forming a high pressure, hot water can easily penetrate into the inside of the ground beans, and the extraction of coffee liquid can be promoted. Second, by forming a high temperature, the extraction of coffee liquid will be promoted. Third, by forming a high temperature and reducing the viscosity of the oil contained in the ground beans, the extraction of the oil will be promoted. Thereby, a coffee beverage with high aroma can be produced.

The temperature of the hot water (high-temperature water) should just exceed 100 degrees Celsius, but higher temperatures are advantageous at the point of extraction of the coffee liquid. On the other hand, in order to increase the temperature of hot water, the cost is generally higher. Therefore, the temperature of the hot water may be set to 105 degrees Celsius or higher, 110 degrees Celsius or higher, or 115 degrees Celsius or higher, for example, 130 degrees Celsius or lower, or 120 degrees Celsius or lower. The air pressure is the air pressure as long as the hot water does not boil.

In S15, the pressure in the extraction container 9 is reduced. Here, the air pressure in the extraction container 9 is switched to the air pressure at which hot water boils. Specifically, the valve 913 is set to an open state, and the solenoid valve 73c is opened for a predetermined time (for example, 1000 ms) and closed. The inside of the container 9 will be released to the atmosphere if it is drawn out. Then, the valve 913 is set to the closed state again.

The inside of the extraction container 9 is rapidly decompressed to an air pressure lower than the boiling point pressure, and the hot water in the extraction container 9 boils all at once. The hot water and ground beans in the extraction container 9 are scattered explosively in the extraction container 9. Thereby, the hot water can be boiled uniformly. In addition, the destruction of the cell wall of the ground beans can be promoted, and the subsequent extraction of coffee liquid can be promoted more. In addition, the boiling can also stir the ground beans and hot water, so that the extraction of coffee liquid can be promoted. In this way, the extraction efficiency of coffee liquid can be improved in this embodiment.

In S16, the withdrawal container 9 is reversed from the upright posture to the inverted posture. Here, the holding member 801 is moved to the raised position and the holding member 811 is moved to the lowered position. Furthermore, the support unit 81B is rotated. Then, the holding member 801 is returned to the lowered position, and the holding member 811 is returned to the raised position. In the withdrawable container 9 in the inverted posture, the neck 90b or the lid unit 91 may be located on the lower side.

In S17, the permeable coffee liquid is drawn and the coffee beverage is delivered to the cup C. Here, the switching valve 10a is switched so that the injection portion 10c communicates with the passage portion 810a of the operation unit 81C. In addition, the valves 903 and 913 are both in the open state. Furthermore, the solenoid valve 73b is opened for a predetermined time (e.g., 10000 ms), and a predetermined air pressure (e.g., 1.7 air pressure (gauge pressure, 0.7 air pressure)) is formed in the extraction container 9. In the extraction container 9, the coffee beverage in which the coffee liquid is dissolved in hot water is sent to the cup C through the filter provided in the lid unit 91. The filter is to limit the leakage of ground bean residue. Complete the withdrawal process with the above.

In this embodiment, the immersion-type extraction in S14 and the permeation-type extraction in S17 are used in combination to improve the extraction efficiency of coffee liquid. In the state where the extraction container 9 is in an upright posture, the ground beans will be accumulated from the waist 90e to the bottom 90f. On the other hand, in the state where the extraction container 9 is in the inverted posture, the ground beans reach from the shoulder 90d to the neck 90b and accumulate. The cross-sectional area of the waist 90e is larger than the cross-sectional area of the neck 90b, and the accumulated thickness of the ground beans in the inverted posture is thicker than the accumulated thickness in the upright posture. That is, the ground beans are relatively thin and widely stacked in the state in which the extraction container 9 is in the upright posture, and relatively thick and narrow in the inverted posture state.

In the case of this embodiment, since the immersion type extraction of S14 is performed in a state where the extraction container 9 is in an upright posture, hot water can be brought into contact with the ground beans in a wide range, and the extraction efficiency of coffee liquid can be improved. However, in this case, there is a tendency that the hot water and the ground beans will partially contact. On the other hand, the through-type extraction of S17 is performed with the extraction container 9 in the upside-down posture, so the hot water passes through the accumulated ground beans while coming into contact with more ground beans. The hot water will come into contact with the ground beans more everywhere, which can improve the extraction efficiency of the coffee liquid.

Returning to FIG. 11(A), the extraction process of S3 is followed by the discharge process of S4. Here, processing related to cleaning in the extraction container 9 is performed. The cleaning of the extraction container 9 is performed by returning the extraction container 9 from the inverted posture to the upright posture, and supplying tap water (clean water) to the extraction container 9. Then, the inside of the extraction container 9 is pressurized, and the water in the extraction container 9 is discharged to the exhaust gas tank T together with the residue of the ground beans.

Through the above, one-time coffee beverage manufacturing process is completed. In the future, the same processing will be repeated for each manufacturing instruction. The time required for one coffee beverage production is, for example, about 60 to 90 seconds.

<7. Outline of the device configuration> As described above, the beverage manufacturing device 1 includes a bean processing device 2 and an extraction device 3 as a manufacturing part. In more detail, the bean processing device 2 includes a storage device 4 and a crushing device 5, and the extraction device 3 includes a fluid supply unit 7, a drive Unit 8, extraction container 9, and switching unit 10 (refer to Figs. 2, 3, etc.). The grinding device 5 receives a cup of roasted coffee beans from the storage device 4, and performs two-stage bean grinding with grinders 5A and 5B. At this time, unnecessary objects such as thin skins are separated from the ground beans by the separating device 6. After the ground beans are put into the extraction container 9, the hot water is injected into the extraction container 9 via the fluid supply unit 7, the posture of the extraction container 9 of the drive unit 8 is reversed, and the switching unit 10 moves from the extraction container 9 to the cup C The delivery of the liquid to provide a cup of drink.

A part of the above-mentioned manufacturing part is covered by the cover part 102 of the transparent cover which is entirely configured as a transparent part, so that the user (for example, the manager of the device 1 and the drinker, etc.) can see from the outside of the device 1. In the present embodiment, in the above-mentioned manufacturing part, a plurality of canisters 40 of a part of the storage device 4 are exposed, and the other elements are substantially housed in a housing 100, but the manufacturing part may also be All of them are housed in the casing 100 as other embodiments. In other words, what is necessary is just to make the cover part 102 cover at least a part of a manufacturing part.

At least a part of the manufacturing department is covered visibly from the outside of the device 1 by the cover 102. For example, when the user is the manager of the device 1, the manager may also prepare the device together with the manufacture of beverages. Action check. When the user is a purchaser of a beverage, the purchaser may sometimes wait for the completion of the manufacture of the beverage while raising the expectation of the beverage. For example, the withdrawing container 9 of the withdrawing device 3 can be viewed from the outside of the device 1 through the cover portion 102, and among several manufacturing processes of the beverage, the extraction process that is of high interest to the user can be observed. The drive unit 8 functions as a posture changing unit that changes the posture of the withdrawal container 9. As described above, the withdrawal container 9 is a movable part that can be reversed up and down in the manufacturing section. Therefore, sometimes the reversal action of withdrawing the container 9 is easier to arouse the user's interest, and the user can observe this and make the user enjoy it.

On the other hand, in order to further improve the quality of the beverage provided by the beverage manufacturing device 1, for example, the improvement of the manufacturing process, the configuration surface of the device 1 to achieve the improvement of the manufacturing process, the control surface, etc. Improvement is also required. As an example, some elements included in the device 1 may be modified. Hereinafter, while referring to FIGS. 12 to 14, an example of the liquid delivery amount adjusting device 720 that can function as the water tank 72 in FIG. 3 will be described.

＜8. Example of the configuration of the liquid delivery volume adjustment device＞ FIG. 12 is a schematic diagram showing the liquid delivery amount adjusting device 720. 13 is a cross-sectional view taken along the line IV-IV in FIG. 12 and a cross-sectional view of another example (configuration example EX31). The liquid delivery amount adjustment device 720 is a device that stores hot water (water) constituting the coffee beverage, like the water tank 72, and has a function of delivering a constant amount of hot water. Thereby, the hot water necessary for a cup of coffee beverage can be delivered sequentially, and the amount of hot water at this time can also be changed. In the following description, the configuration having the same function as the configuration related to the water tank 72 is given the same reference numeral.

The liquid feeding amount adjustment device 720 has a tank 720a for storing hot water. The outer wall of the groove 720a includes a peripheral wall 721, an upper wall 723 joined to the upper end of the peripheral wall 721, and a bottom wall 724 joined to the lower end of the peripheral wall 721. As shown in the cross-sectional view of FIG. 13, the groove 720a is the whole Has a cylindrical shape. A partition wall 722 is provided in the groove 720a, and the internal space of the partition wall 722 is divided into an outer cylindrical space 725 and an inner cylindrical space 726A. In the case of the present embodiment, the partition wall 722 is a cylindrical wall arranged concentrically with the peripheral wall 721, but the partition wall 722 may be eccentric to the peripheral wall 721 as shown in the configuration example EX31 of FIG.

The space 725 constitutes a storage portion for storing hot water. The space 725 is also referred to as a storage portion 725. In the upper part of the space 726A, the movable member 727c is arranged, and the lower space 726 constitutes a storage portion for storing hot water. The space 726 is also referred to as a storage portion 726. By partitioning the storage portion 725 and the storage portion 726 by the partition wall 722 of the common wall, the groove 720a can be reduced in size rather than being partitioned by separate walls.

The storage unit 725 is provided with a heater 72a for heating the water in the storage unit 725 and a temperature sensor 72b for measuring the temperature of the water. The heater 72a maintains the temperature of the accumulated hot water at a predetermined temperature (120 degrees Celsius in this embodiment) based on the detection result of the temperature sensor 72b. For the heater 72a, for example, the temperature of hot water is turned on at 118 degrees Celsius and is turned off at 120 degrees Celsius.

In the upper wall 723, the portion defining the storage portion 725 is connected to a pipe for supplying air pressure in the gas tank 71 (refer to FIG. 3), and a solenoid valve 72f is provided here. The liquid feeding amount adjustment device 720 is equipped with a sensor (not shown, for example, a sensor corresponding to the pressure sensor 72g in FIG. 3) that detects the air pressure in the storage portion 725, and the solenoid valve 72f is switched to the pressure adjustment The valve 72e (refer to FIG. 3) supplies and shuts off the pressure-regulated air pressure to the storage portion 725. The solenoid valve 72f is controlled to open and close so that the air pressure in the storage section 725 is maintained at 3 atmospheric pressure, except for the supply of water to the storage section 725.

In the upper wall 723, the part delimiting the storage portion 725 is also connected to a pipe that communicates the storage portion 725 to the atmosphere, and a solenoid valve 72h is provided here. When the tap water is supplied to the storage section 725, the tap water is smoothly replenished to the storage section 725 by the water pressure, and the pressure of the storage section 725 is reduced to less than 2.5 atmospheric pressure by the solenoid valve 72h . The solenoid valve 72h switches whether to release the inside of the water tank 72 to the atmosphere, and releases the inside of the storage portion 725 to the atmosphere during pressure reduction. In addition, the solenoid valve 72h releases the storage section 725 to the atmosphere when the air pressure in the storage section 725 exceeds 3 atmospheres, and maintains the storage section 725 at 3 atmospheres, except when the water is supplied to the storage section 725.

In the bottom wall 724, the portion defining the storage portion 725 is a pipe L2 that connects the tap water to the storage portion 725, and a solenoid valve 72d is provided here. The solenoid valve 72d is opened and closed based on the detection result of the water level sensor 72c described later, and controls the water level of the hot water in the storage unit 725.

In the bottom wall 724, the portion delimiting the storage portion 725 is also connected to a pipe L2' for discharging the hot water in the storage portion 725, and a solenoid valve 72d' is provided here. The solenoid valve 72d' is opened when the hot water in the storage unit 725 is discarded, and the hot water in the storage unit 725 is discharged to the pipe L2'.

The storage portion 726 is a space whose volume can be changed by the movement of the movable member 727c. The storage unit 726 supplies hot water from the storage unit 725 via the pipe 728a, the solenoid valve 728, and the pipe 728b. The piping 728a connects the bottom wall 724 between the portion defining the storage portion 725 and the solenoid valve 728. The piping 728b connects the bottom wall 724 between the portion defining the storage portion 726 and the solenoid valve 728.

In the example of FIG. 12, the solenoid valve 728 is a three-way valve, and can switch the communication and blocking of the pipe 728b and the pipe 728a, and the communication and blocking of the pipe 728b and the pipe 728c. In addition, the solenoid valve 728 can block any piping from each other. The piping 728c is a piping for sending out the hot water in the storage part 726 to the extraction container 9.

By switching the communication and blocking of the pipe 728b and the pipe 728a, the communication and blocking of the storage portion 725 and the storage portion 726 can be switched. By switching the communication and blocking of the pipe 728b and the pipe 728c, the delivery and storage of the hot water in the storage section 726 can be switched.

When the solenoid valve 728 communicates with the pipe 728b and the pipe 728a, the pipe 728b and the pipe 728c are blocked. Conversely, when the pipe 728b and the pipe 728c are connected, the pipe 728b and the pipe 728a are blocked. The arrow indicated by the solenoid valve 728 in the figure indicates the operating state of the solenoid valve 728. In the example of FIG. 12, it indicates a state where the pipe 728b and the pipe 728c are connected, and the pipe 728b and the pipe 728a are blocked.

In addition, here, by setting the solenoid valve 728 as a three-way valve, the configuration can be switched by one solenoid valve 728. However, it is also possible to divide the piping 728b into two, and to provide a valve for switching the communication and blocking between the piping 728b on one side and the piping 728a, and a valve for switching the communication and blocking between the piping 728b and the piping 728c on the other side.

The liquid feeding amount adjustment device 720 includes a drive unit 727. The drive unit 727 is controlled in accordance with the amount of hot water sent from the storage section 726 to change the volume of the storage section 726. According to the size of the coffee cup, the necessary amount of hot water for a cup is different. The drive unit 727 adjusts the volume of the storage section 726 so that an appropriate amount of hot water is sent from the storage section 726 according to the size of such a coffee cup.

The drive unit 727 is a mechanism that changes the volume of the storage portion 726 by moving the movable member 727c up and down. The movable member 727c is a piston-shaped member that is inserted into the space 726A and slides in the vertical direction, and its bottom surface 727d constitutes the upper wall of the storage portion 726. Based on this viewpoint, the movable member 727c is called a piston unit or the like, and the space 726A may also be called a cylinder unit or the like. As the bottom surface 727d rises and falls, the volume of the storage portion 726 changes.

In addition, the volume of the storage portion 726 may be changed not by moving the position of the upper wall as in this example, but by moving the position of the lower or side wall.

The movable member 727c includes a sealing member (not shown) that forms a seal with the inner surface of the partition wall 722, and slides on the inner surface of the partition wall 722 in a liquid-tight manner. However, a groove 727e extending in the vertical direction is formed on the peripheral surface of the movable member 727c, and the groove 727e has a gap with the inner surface of the partition wall 722.

This groove 727e is formed to communicate with the opening 722a penetrating the partition wall 722 in the thickness direction. The opening 722a is formed at a position higher than the highest water level of the hot water of the storage portion 725 (position of the sensor 731b described later), and is an air communication portion that communicates the storage portion 725 with the space 726A. Air communicates between the storage part 725 and the storage part 726 via the opening 722a and the groove 727e, and the air pressure in these spaces becomes the same. In addition, when the storage portions 725 and 726 are always set to atmospheric pressure, a passage communicating with the atmosphere may be separately provided.

The drive unit 727 is a moving mechanism that includes a motor 727a supported on the upper wall 723 as a drive source, and a screw shaft 727b as a movable member 727c. The screw shaft 727b is extended in the up and down direction, and is rotated by the driving force of the motor 727a. The movable member 727c has a spiral hole 727f opened on the upper surface, and the spiral shaft 727b is engaged with the spiral hole 727f. The movable member 727c is provided with a stopper (not shown), and moves in the vertical direction by the rotation of the screw shaft 727b. The stopper may be, for example, a concave portion and a convex portion extending in the up-down direction provided on the inner surface of the partition wall 722 and the peripheral surface of the movable member 727c.

Here, the screw mechanism formed by the screw shaft 727b and the screw hole 727f is used as a moving mechanism for moving the movable member 727c, but it is not limited to this, and other mechanisms such as a rack mechanism may also be adopted.

The water level sensor 72c is a measuring unit that measures the water level of the hot water in the storage unit 725. The water level sensor 72c includes a hollow cylindrical storage portion 729 extending up and down, a float 730 provided in the storage portion 729, a sensor 731a on the lower side of the detection float 730, and a sensor on the upper side. 731b.

The storage portion 729 communicates with the storage portion 725 by a communicating portion 729a located below the sensor 731a, and communicates with the storage portion 725 by a communicating portion 729b located above the sensor 731b. The hot water in the storage part 725 flows into the storage part 729 via the communication part 729a. The communication part 729b is an air communication part which connects the storage part 725 and the storage part 729, and air will communicate in the storage part 725 and the storage part 729 via the communication part 729b. Therefore, the water level of the hot water in the storage unit 729 is equal to the water level of the hot water in the storage unit 725.

In the case of this example, the storage portion 729 is composed of a transparent member such as glass or acrylic. Thereby, the water level of the hot water in the storage unit 729 can be visually recognized from the outside, and as a result, the user can confirm the water level of the hot water in the storage unit 725. Of course, it is also possible to adopt a configuration in which a permeable part is provided in a part of the peripheral wall (721) of the storage part 725 so that the water level can be seen.

The buoy 730 can be any thing as long as it floats in the hot water in the storage part 729.

The sensors 731a and 731b are, for example, light sensors (photointerrupters), and detect the float 730 from the outside of the storage portion 729. Once the float 730 is detected by the sensor 731a, the solenoid valve 72d is opened to supply water to the storage part 725. That is, the sensor 731a monitors the lower limit of the water level of the hot water in the storage unit 725. The lower limit of the water level is set to a position higher than that of the heater 72a, which can prevent the heater 72a from burning out.

Once the float 730 is detected by the sensor 731b, the solenoid valve 72d is closed to stop the water supply to the storage portion 725. That is, the sensor 731b monitors the upper limit of the water level of the hot water in the storage unit 725.

The same structure as that of the water level sensor 72c may be constructed inside the storage portion 725. However, as in this example, by constructing the water level sensor 72c outside the storage section 725, it is easy to confirm the water level of the storage section 725 from the outside.

Next, referring to FIG. 14, an example of the operation of the liquid delivery amount adjusting device 720 will be described. First, the drive unit 727 adjusts the volume of the storage portion 726 according to the cup size and the like. The state ST61 shows the state. In the example of the same figure, the movable member 727c is lowered, and the volume of the storage portion 726 is set to a smaller volume than the example of FIG. 13. The solenoid valve 728 communicates the pipe 728b and the pipe 728c, and hot water is not supplied from the storage section 725 to the storage section 726.

Once the volume of the storage portion 726 is set, the drive unit 727 is stopped, and the pipe 728b and the pipe 728a are communicated with the solenoid valve 728. The storage section 725 and the storage section 726 have the same air pressure, and the storage section 726 is located on the bottom side of the tank 720a. Therefore, hot water is supplied from the storage part 725 to the storage part 726 by the head pressure of the hot water in the storage part 725. In the case of this example, since it is formed at a position lower than the lowest water level of the hot water in the storage portion 725 (position of the sensor 731a), there is often a head difference between the storage portion 725 and the storage portion 726 (the difference between the storage portion 725 and the storage portion 726). Hot water is higher). Therefore, until the storage section 726 is full, hot water is supplied from the storage section 725 to the storage section 726. The state ST62 indicates that the storage portion 726 is in a full state. Hot water also enters in the groove 727c, but the groove 727c has a sufficient volume to ensure the communication of air, and can be set to an extremely small amount.

In the case of this example, the heater 72a is not provided in the storage portion 726, but the storage portion 726 is surrounded by the storage portion 725, so the heat retention performance of the stored hot water can be ensured. In addition, the volume of the storage portion 726 may be changed by the drive unit 727 in the state ST62.

The supply of hot water from the storage section 725 to the storage section 726 may be other methods, but in this example, by using the difference in head between the storage section 725 and the storage section 726, hot water can be supplied with a relatively simple configuration.

Next, the hot water stored in the storage section 726 is sent out. As shown in the state ST63, the solenoid valve 728 connects the pipe 728b and the pipe 728c, and the hot water can be sent from the pipe 728c to the extraction container 9 by its own weight or the air pressure of the storage portion 726. After the sending of hot water starts, the operating state of the solenoid valve 728 is also blocked between any piping, and the hot water of the storage unit 726 can also be sent out in stages. For example, for the steaming process (S11 in Fig. 11(B)), the delivery of hot water may be interrupted, and then the process of delivering the remaining hot water (S12 in Fig. 11(B)).

In short, the full amount of hot water stored in the storage section 726 is sent out. The full delivery confirmation can be performed during the opening time of the solenoid valve 728 (the communication time between the pipe 728b and the pipe 728c). Each time the hot water stored in the storage section 726 is sent out, the control valve 72d may be opened, and water corresponding to this amount may be supplied to the storage section 725.

According to the above example, the amount of hot water sent out can be adjusted. The adjustment of the liquid delivery volume generally uses a flow sensor to open and close the valve based on the detection result. However, in the case of high-temperature liquids or special liquids, the corresponding flow sensor may not be commercially available or expensive. In contrast, according to the above-mentioned example, by adopting a method of adjusting the volume of the storage portion 726, it is possible to adjust the delivery amount of hot water without the need for a flow sensor.

＜9. Example of operation control when using the liquid delivery volume adjustment device＞ By using the above-mentioned liquid delivery amount adjusting device 720, for example, a part of the manufacturing process can be changed to further improve the quality of the beverage provided by the beverage manufacturing device 1. Hereinafter, referring to FIG. 15, an example of the control processing of the device 1 executed by the processing unit 11 a (refer to FIG. 10) of the control device 11 will be described. In addition, for the description omitted in the following, reference may be made to the above-mentioned steps in FIGS. 11(A) and 11(B) and the operation content of the liquid feeding amount adjusting device 720 in FIGS. 12 to 14.

Fig. 15 shows a control example related to one coffee beverage production operation. First, the pre-heat treatment S1 is the heating process S101 and S102 divided into at least two times (to distinguish it from S1 in FIG. 11(A), it is referred to as S1').

S101 is a process of injecting hot water into the extraction container 9 (container body 90) and heating the extraction container 9 in advance. First, the solenoid valve 728 is controlled to connect the pipe 728 a and the pipe 728 b to move a small amount of hot water from the storage section 725 to the storage section 726. Then, the solenoid valve 728 is controlled to communicate the pipe 728b and the pipe 728c, and the hot water of the storage unit 726 is sent out to the extraction container 9 via the pipe L3. Next, the solenoid valve 73 is controlled to pressurize the inside of the extraction container 9 and the hot water in the extraction container 9 is discharged to the waste tank T.

The inside of the drawn-out container 9 and the pipes L2 to L3 are preheated by S101, and it is possible to prevent the hot water from cooling during the beverage production in each process described later. In addition, by performing S101, it is possible to wash away residues (liquid residues, etc.) in the flow path generated during the previous or even past extraction.

In S102, the steam generated in the storage portions 725 and 726 is supplied into the container body 90, and the container 9 is drawn out and heated. This steam can be generated by depressurizing the storage parts 725 and 726 to boil the hot water in the storage parts 725 and 726, and can be realized by the same procedure as S15 (see FIG. 11(B)). After the supply of the steam to the extraction vessel 9 or the heating of the extraction vessel 9 by the steam is completed, the solenoid valve 728 is controlled to block the pipe 728b and the pipe 728c.

By performing S102, the whole extraction container 9 can be heated uniformly. Thereby, it is possible to extract liquid without unevenness, for example, from a ground bean at a desired temperature, and as a result, the quality of the beverage can be improved. In addition, in S102, the air pressure of the storage portions 725 and 726 drops, and the liquid therein starts to boil. Therefore, the liquid may be stirred to make the temperature uniform.

Incidentally, the piping L3, which functions as a connection portion connecting the storage portions 725 and 726 and the extraction container 9 and forms a flow path between them, is also heated together with the extraction container 9 in S102. Thereby, when the liquid passes through the pipe L3, the liquid does not become cold.

Here, as described above, the extraction container 9 has valves 903 and 913, which serve as inlets or outlets for hot water and steam. The hot water is used as the liquid to be extracted, and the steam is used. The beverage liquid (in this example, the coffee liquid) obtained by the above extraction or the heating in S102. In this example, in S102, the steam flows into the extraction container 9 from the valve 913, and flows out of the extraction container 9 from the valve 903. When vapor flows into the extraction container 9 from the valve 913, the valve 903 is opened, whereby when the vapor is liquefied in the extraction container 9 to form a liquid, the liquid will not stay in the extraction container 9 for a long time. It can flow out from the valve 903 to the outside of the extraction container 9. According to this aspect, for example, when a beverage is manufactured by each process described later, the taste, flavor, and the like of the beverage will not be unintentionally thinned, which is advantageous for improving the quality of the beverage.

Or, after filling the extraction container 9 with steam, both the valves 903 and 913 may be closed and the extraction container 9 may be vibrated. The vibration of the withdrawn container 9 can be realized by the motor 823 and/or 824 (refer to FIG. 9) of the middle unit 8B. By applying vibration to the extraction container 9 filled with steam, the steam is uniformly expanded in the extraction container 9 and the entire extraction container 9 can be uniformly heated.

In addition, instead of/in addition to the above-mentioned S102, the heating of the extraction container 9 by steam may be performed before S101. That is, the order of execution of S101 and S102 may be reversed, or S102 may be executed twice before and after S101. By performing S102 before S101, it may be easy to remove the residue generated during the previous or even past extraction in S101.

After the pre-heat treatment S1' is performed as described above, S2 is performed in the same procedure as in FIG. 11(A), and then the extraction process is performed (to distinguish from S3 in FIG. 11(A), it is referred to as S3'). In the extraction process S3', the hot water injection S12 for the main extraction is at least two injection hot water processes S121 and S122. S121 of the first injection of hot water is performed after S11 and before S13. Then, S13~S16 are performed in the same procedure as in Fig. 11(B).

Here, in S14, the ground beans to be extracted are stacked in the extraction container 9 in the upright posture with a relatively thin accumulation thickness, and the ground beans are immersed in the hot water supplied in S121. In S15, the hot water in the extraction container 9 is boiled, and in S16, the extraction container 9 is reversed to form an inverted posture. After S17, the second hot water injection S122 is performed together with S17.

In the figure, for the sake of distinction, it is shown that S122 is performed after S17, but it is preferable that S122 is performed after the start of S17 and roughly simultaneously with S17. In other embodiments, S17 may be performed roughly at the same time as S122 after the start of S122. That is, S122 and S17 may be at least partially in parallel, for example, hot water injection and delivery, etc., or they may be concentrated in one process K.

As mentioned above, when the withdrawal container 9 is in the upright position, the ground beans will accumulate from the waist 90e to the bottom 90f. On the contrary, when the withdrawal container 9 is in the upside-down position, the ground beans will go from the shoulder 90d to the neck 90b. accumulation. That is, the extraction container 9 includes the thick part from the waist 90e to the bottom 90f and the thin part from the shoulder 90d to the neck 90b. The ground beans are accumulated in the thick part in the upright posture, and in the inverted posture It is piled up in the thin part.

In the above-mentioned S17 through-type extraction, since the extraction container 9 is in an inverted posture, the hot water in the extraction container 9 is passed through the ground beans that are thicker than in the upright position and comes into contact with the ground beans everywhere. Therefore, the efficiency of permeable extraction can be improved. Here, the second hot water injection S122 will be performed together with S17. Therefore, the extraction container 9 is to send out the beverage liquid obtained by the immersion extraction of the hot water received in S121, and additionally receive it by S122. Hot water. In addition, the hot water that is additionally flowed into the extraction container 9 by S122 is not substantially used for immersion extraction, and is mainly used for permeation extraction. According to such an extraction form, a permeable extraction unique flavor can be effectively imparted to the beverage, and the quality of the beverage can be improved.

The amount of hot water injected in S121 and the amount of hot water injected in S122 can also be set or changed by the user, for example, to adjust the ratio of immersion type extraction and permeation type extraction. Thereby, it is possible to produce a beverage according to the quality of the user's taste in some cases.

Figs. 16(a) to 16(h) and Figs. 17(i) to 17(о) are schematic diagrams for explaining the control mode of the liquid feeding amount adjusting device 720 corresponding to the steps of Fig. 15 described above. In order to make understanding easier, in the following description, it is assumed that the simple mode using the liquid delivery amount adjustment device 720 is used. The solenoid valve 728 of the three-way valve is distinguished as a valve that switches the communication between the pipe 728a and the pipe 728b and shuts off 7281, and a valve 7282 that switches the communication and blocking of the pipe 728b and the pipe 728c.

Fig. 16(a) shows the initial state of the liquid delivery amount adjusting device 720, and the beverage production device 1 is waiting for a start instruction of beverage production. In the initial state, as shown schematically in the figure, valves 7281 and 7282 are all locked.

Figs. 16(b) to 16(c) show the form of the liquid feeding amount adjusting device 720 corresponding to the above-mentioned S101 (heating treatment of the extraction container 9 using a small amount of hot water). In the process of FIG. 16( b ), the valve 7281 is opened to move a small amount of hot water from the storage part 725 to the storage part 726 as shown in the dotted arrow. Next, after closing the valve 7281, in the process shown in FIG. 16(c), the valve 7282 is opened, and the hot water in the storage portion 726 is supplied to the extraction container 9 as shown by the dotted arrow. Thereby, the inside of the extraction container 9 and the pipes L2 to L3 are heated.

Fig. 16(d) to Fig. 16(e) show the form of the liquid feeding amount adjusting device 720 corresponding to the above-mentioned S102 (heating treatment of the extraction vessel 9 using steam). In the process of FIG. 16(d), the pressure in the storage portions 725 and 726 is reduced to boil the hot water in the storage portions 725 and 726, thereby generating steam in the storage portions 725 and 726. Since the valve 7282 is in an open state, the generated steam is supplied to the extraction container 9 via the pipe 728c as shown by the dotted arrow. In addition, in the process of FIG. 16(d), the hot water in the storage portions 725 and 726 may also be stirred by the above-mentioned boiling. When the temperature of the stirred hot water does not reach a predetermined value (for example, 118 degrees Celsius) , The heater 72a (refer to FIG. 12) will be driven. Then, in the process of FIG. 16(e), the valve 7282 is closed, and the supply of steam to the extraction container 9 is stopped. Thereby, the whole extraction container 9 is uniformly heated.

Fig. 16(f) to Fig. 16(h) show the form of the liquid feeding amount adjusting device 720 corresponding to the preparation process for executing the extraction process S3'. In the process of Fig. 16(f), after returning the storage parts 725 and 726 to 3 atmospheric pressure, in the process of Fig. 16(g), the valve 7281 is opened, as shown by the dotted arrow, so that Hot water (for example, about 180 cc) moves from the storage part 725 to the storage part 726. After the movement of the hot water from the storage part 725 to the storage part 726 is completed, the valve 7281 is closed in the process of FIG. 16(h). In addition, the amount of a cup may be preset or selected by the user, or may be determined according to the size of the cup placed on the placing part 110, or may be a fixed value. Although not shown here, the grinding process S2 may be performed in parallel between the processes of FIGS. 16(f) to 16(h), thereby shortening the time until the beverage is manufactured.

Figs. 17(i) to 17(j) show the form of the liquid feeding amount adjusting device 720 corresponding to the injection hot water S11 for steaming. The valve 7282 is opened in the process of FIG. 17(i), and after a predetermined time has passed, the valve 7282 is closed in the process of FIG. 17(j). Thereby, a part (for example, about 30 cc) of the hot water stored in the storage portion 726 flows into the extraction container 9 for the stuffing of S11 as shown by the dotted arrow.

Figs. 17(k) to 17(l) show the form of the liquid feeding amount adjusting device 720 corresponding to the first injection hot water for main extraction S121. After the steaming of the ground beans is finished, the valve 7282 is opened in the process of Fig. 17(k), and after a predetermined time has passed, the valve 7282 is closed in the process of Fig. 17(l). Thereby, a part (for example, about 40 cc) of the remaining hot water in the storage portion 726 flows into the extraction container 9 as shown by the dotted arrow.

Although not shown here, after the process of FIG. 17(1), S13 to S17 are performed. The details will be described later. In S13 of this example, hot water (for example, about 30 cc) is injected together with the pressurization in the extraction container 9.

FIG. 17(m) is a form of the liquid supply amount adjusting device 720 corresponding to the second injection hot water for main extraction S122. By opening the valve 7282 in the process of FIG. 17(m), the remaining hot water (for example, about 80 cc) in the storage portion 726 will additionally flow into the extraction container 9 as shown by the dotted arrow. As described above, S122 is performed roughly at the same time as S17. Here, the hot water flowing into the extraction container 9 is not actually used in the immersion type extraction, and is mainly used for the transmission type extraction.

Then, S17 is completed by delivering substantially all of the beverage from the extraction container 9 to the cup. Here, after S122 and before S17 is finished, the steam of the storage parts 725 and 726 and the air pressure from the compressor 70 are used locally to promote the delivery of the beverage. The steam in the storage parts 725 and 726 can be generated by the same procedure as in S102 (the process of Fig. 16(d) to Fig. 16(e)). That is, in the process of FIG. 17(n), the pressure in the storage parts 725 and 726 is reduced to boil hot water, thereby generating steam in the storage parts 725 and 726, and the steam is supplied to the extraction container through the pipe 728c 9. At this time, as in the process of FIG. 16(d), the hot water in the storage portions 725 and 726 is appropriately stirred, and the heater 72a is driven as required. Then, in the process of FIG. 17(о), the valve 7282 is closed to stop the supply of the steam. In addition, when the delivery of the beverage is promoted, the inside of the withdrawal container 9 is adjusted to about 1.6 to 2 atmospheric pressure, for example.

Fig. 18 is a diagram for explaining how the air pressure in the extraction container 9 changes during the extraction process S3'. The horizontal axis represents the time axis, and the steps corresponding to the periods T1 to T11 (S11, etc.) are also displayed while displaying the periods T1 to T11. The vertical axis represents the air pressure P in the extraction container 9 in each of the periods T1 to T11.

The period T1 to T2 is a period corresponding to the injection hot water S11 for steaming. In the period T1, the inside of the extraction container 9 is pressurized to about 1.8 atmospheric pressure, and hot water (about 30 cc) for steaming is poured into the extraction container 9. The timing of the inflow of hot water into the extraction container 9 may be any within the period T1, but it may be preset or selected by the user, or may be changed according to the type of beverage. Then, use this hot water to steam and grind beans. Let this period (approximately 15 seconds) be period T2.

The period T3 is a period corresponding to the first injection of hot water S121. In the period T3, the inside of the extraction container 9 is pressurized to 3 atmospheric pressure, and hot water (about 40 cc) for the main extraction is poured into the extraction container 9 as S121.

The period T4 is a period corresponding to the pressurization S13 in the extraction container 9. In the period T4, the inside of the extraction container 9 is pressurized to 5 atmospheric pressure, and hot water (about 30 cc) is poured into the extraction container 9.

Here, the amount of injected hot water can be adjusted between periods T3 and T4. For example, the injection of hot water of about 70 cc may be completed in period T3. In the periods T3 and T4, the point of injecting hot water while pressurizing the inside of the extraction container 9 is common, but in this example, these pressurization modes are different from each other. For example, during the period T3~T4 pressurization, the pressurization mode will be relaxed on the way (P=3 atmospheric pressure). For example, the timing between the periods T3 and T4 can also be specified as the inflection point of the air pressure P. By controlling and adjusting the pressurized form of T3~T4 during the period of T3~T4, the beverage liquid obtained in S14 may be immersed in the subsequent process to expand the range of taste, flavor, etc. that can be expressed.

The period T5 is a period corresponding to the immersion extraction S14. After the inside of the extraction container 9 reaches 5 atmospheres, the state is maintained. Let this period (about 1 second) be period T5. Thereby, the coffee liquid of the beverage liquid is extracted from the ground bean to be extracted.

The period T6 to T8 is a period corresponding to the pressure reduction S15 in the extraction container 9. In the period T6 to T7, the aforementioned pressure reduction is divided into two stages and performed. In the period T6, first, the pressure in the extraction container 9 is reduced from 5 atmospheric pressure to 1.5 atmospheric pressure (abrupt pressure reduction) in a relatively short time, and then, it waits for a predetermined period (about 3 seconds). Next, in the period T7, the pressure in the extraction container 9 is reduced to 1 atmosphere, and then, it waits for a predetermined period (about 1 second).

As described above, the liquid in the pumped-out container 9 is boiled and stirred by reducing pressure S15. According to the reduced pressure mode of this example, first, a part of the liquid in the container 9 will be boiled and stirred by the first stage of decompression in the period T6, and then the other part of the liquid in the container 9 will be extracted It can also be boiled and stirred by the pressure reduction in the second stage of the period T7. Therefore, it is possible to appropriately perform, for example, agitation of the entire liquid in the drawn-out container 9. In this case, it is sometimes advantageous to use, for example, when there is unevenness in concentration or composition in the drawn-out beverage liquid. Then, during the period T8, the inside of the extraction vessel 9 is returned to 1.5 atmospheric pressure to stabilize the boiling, and the liquid (for example, about 5 cc) remaining in the flow path (pipes L2, L3, etc.) is pushed into the extraction vessel 9.

The period T9 is a standby period (approximately 2 seconds) after the reversal S16 of withdrawing the container 9. In addition, the timing of the start of the period T9 corresponds to the timing when the above-mentioned reversal S16 is performed. In the period T9, in the extraction container 9 reversed in S16, the ground beans to be extracted are accumulated in the lower portion of the extraction container 9 with a relatively thick accumulation thickness. In the period T9, the inside of the extraction container 9 is depressurized to make 1 atmosphere.

The period T10 to T11 corresponds to the period of the permeable extraction S17, whereby the beverage is delivered from the extraction container 9 to the cup. As described above, the second injection of hot water S122 is performed roughly at the same time as S17, and the hot water (approximately 80 cc) that has additionally flowed into the extraction container 9 is mainly used for permeation extraction.

In this example, in the period T10, for example, after S122, the inside of the extraction container 9 is pressurized to 1.6 atmospheric pressure, and in the subsequent period T11, the inside of the extraction container 9 is pressurized to 2 atmospheric pressure to promote the delivery of the beverage. In the period T10, the vapor of the storage portions 725 and 726 is used to promote the delivery of the beverage, and in the period T11, the air pressure from the compressor 70 is used to promote the delivery of the beverage. With this, it is possible to provide all of the beverage to be sent (including the liquid in the flow path) to the cup in a relatively short time. FIG. 19 is a waveform showing the amount of hot water in the extraction container 9 (the state of change in the amount of hot water) that changes along with the passage of time with a broken line in FIG. 18. In this example, all about 185cc of beverage will be served.

Each of the above-mentioned periods T1, etc., corresponds to each step of S11, etc. or its sub-steps in more detail, and is summarized as follows. that is, Period T1: Hot water injection project for steaming, Period T2: Steaming project, Period T3: The first hot water injection project, Period T4: Pressurization project, Period T5: High-pressure impregnation project, Period T6: The rapid decompression process after high-pressure immersion, or the atmospheric liberation process (first half) to liberate the extraction vessel 9 into the atmosphere, Period T7: The sudden decompression process after the standby state, or the atmospheric liberation process to release the extracted container 9 to the atmosphere (second half), Period T8: Waiting for the liquid remaining in the flow path to flow into the extraction vessel 9 Period T9: Container posture change process (container reversal process), and standby process waiting for the accumulation of the extracted objects in the extracted container 9, Period T10: The second hot water injection process, beverage delivery process (first half), or steamed beverage delivery promotion process, Period T11: Beverage delivery project (second half), or beverage delivery promotion project using air pressure.

In the above-mentioned FIG. 19, as the target value (or set value) of the air pressure and the amount of hot water in the extraction container 9 that change with the passage of time, how these actual values change may be added. The ground is drawn on the information display device 12 (refer to FIG. 1, etc.). Thereby, when the user is a purchaser of a drink, etc., the user may not be bored with waiting. In addition, when the user is a manager or the like of the device 1, the user can sometimes confirm whether the production of beverages by the device 1 is properly performed.

20 is a drawing showing the actual value of the air pressure and the amount of hot water in the extraction container 9 and the elapse of time (in real time) superimposed on the above-mentioned target value, as it can be displayed on the information display device 12 during the manufacture of beverages Information. That is, FIG. 20 is a waveform showing the state of the actual value changes of the air pressure and the amount of hot water in the extraction container 9 added to FIG. 19. These actual values can be measured by the pressure sensor and the temperature sensor respectively as actual measured values. In the figure, the solid line represents the change pattern of the target value of the air pressure in the extraction container 9 when a cup of beverage is drawn, and the one-dot lock line represents the change pattern of the actual measured value of the air pressure in the extraction container 9. In addition, the broken line indicates the change pattern of the target value of the amount of hot water in the extraction container 9, and the two-dot chain line indicates the change pattern of the actual measurement value of the amount of hot water in the extraction container 9.

The example in FIG. 20 shows that the current process is in the middle of the period T6 (S15), and the actual measured values of the air pressure and the amount of hot water in the extraction container 9 are drawn from the period T1 to the time (in the middle of the period T6) . Here, the actual measured value of the air pressure in the extraction container 9 at this point in time is 1.2 atmospheric pressure, and the actual measured value of the amount of hot water is 100 cc. In addition, the above measured values will continue to be drawn in subsequent projects. According to such a display mode, when the actual measurement value does not reach the target value or the actual measurement value deviates greatly from the target value, the user will experience the occurrence of leakage in the flow path and the status of the various elements (piping, valves, etc.) forming the flow path You can respond quickly to bad things.

20 is an example of the manner in which the target values of the air pressure and the amount of hot water in the extraction container 9 and the changes in the actual measured values are displayed on the information display device 12, but some of these may be displayed on the information Display device 12. For example, only the target value and actual measured value of air pressure may be displayed, or only the target value and actual measured value of the amount of hot water may be displayed. Or, the calculation result of the above-mentioned target value and actual measurement value (for example, the state of the change of the deviation amount) may be displayed.

The form of the change in the above-mentioned target value of the air pressure and the amount of hot water in the extraction container 9 is prepared in advance as a plurality of patterns, and the user can also select from among these patterns corresponding to the hobbyist. The information representing the plural samples mentioned above may be stored in advance in the memory 11b (refer to FIG. 10), or may be obtained from the server 16 via the communication network 15. Furthermore, the user's above selection can be realized by the information display device 12 of a touch panel display.

In addition, when a cup of beverage is drawn, the changes in the above-mentioned target value and actual measurement value of the air pressure and the amount of hot water in the drawn-out container 9 are displayed on the information display device 12 throughout the entire period T1 to T11, indicating such changes. The information can be stored in the memory 11b, for example. Therefore, the user can also perform a predetermined operation via the information display device 12 as needed to display the information again. In this way, the user can also confirm the changes in the above-mentioned target value and the actual measurement value at the time of beverage production performed in the past.

In addition, the periods T1 to T11 are schematically shown in FIG. 18 to FIG. 20 with the same length as each other. However, these are only provided in the actual information display device 12 at an interval corresponding to the actual time. Just display it.

The heating of the container 9 is withdrawn. Thereby, the entire extraction container 9 can be uniformly heated. For example, the subsequent permeable extraction S17 can extract the beverage liquid (coffee liquid) without unevenness at a desired temperature, and as a result, the beverage can be improved in quality.

According to the present embodiment, the ground beans to be extracted are accumulated in the extraction container 9 in the upright posture and immersed in the liquid (hot water). This liquid flows into the extraction container 9 by S121 of the first injection of hot water. Then, the draw-out container 9 is placed in an upside-down posture to increase the thickness of the ground beans (see S16), and the draw-out container 9 in the upside-down posture sends out the beverage liquid to the cup via the injection portion 10c (see S17). In the extraction container 9 that is being sent out, the remaining liquid (hot water) is additionally poured in by S122 of the second injection of hot water. The liquid that is additionally poured is mainly used for permeation type extraction. According to such an extraction form, it is possible to impart a unique flavor to the beverage, for example, permeation type extraction. In addition, the ratio of immersion extraction and penetration extraction can be adjusted, and the range of taste, flavor, etc. that can be expressed can sometimes be expanded. As a result, the quality of the beverage can be improved.
