Thereby, a special cup can be provided to a person who needs a drink.

In the present embodiment, the cover portion 102 is formed of a light-transmitting material such as acryl (Acryl) or glass, and constitutes a transparent cover whose entirety is a transmission portion. Therefore, the inner mechanism covered by the cover part 102 can be seen from the outside. In the case of the present embodiment, a part of the production section for producing coffee beverages can be seen through the cover section 102 . In the case of the present embodiment, the entirety of the main body portion 101 is an impermeable portion, and it is difficult to see the inside thereof from the outside.

Fig. 2 is a partial front view of the beverage production device 1, a front view of the beverage production device 1, and a diagram showing a part of the production section visible to the user. The cover portion 102 or the information display device 12 is shown with imaginary lines.

The front casing 100 of the beverage production device 1 has a double structure consisting of a main body 101 and a cover 102 on the outside (front side). A part of the mechanism of the manufacturing unit is disposed between the main body 101 and the cover 102 in the front-rear direction, and the user can visually recognize it through the cover 102 .

In the case of this embodiment, a part of the mechanism of the manufacturing section that the user can visually recognize through the cover section 102 is the collective conveyance section 42, grinders 5A, 5B, separation device 6, extraction container 9, etc. which will be described later. A rectangular recess 101a recessed to the inner side is formed on the front portion of the main body 101, and the extraction container 9 and the like are located on the inner side in the recess 101a.

Through these mechanisms, it is possible to view from the outside through the cover part 102 Admittedly, it is sometimes easier for managers to check points or check actions. And, for those who need beverages, sometimes they can enjoy the manufacturing process of coffee beverages.

In addition, the cover part 102 is supported by the main body part 101 in the right end part via the hinge (hinge) 102a so that it can open and close in a horizontal opening type.

Moreover, the cover part 102 may be made into the structure which cannot be opened and closed.

FIG. 3 is a schematic diagram of the functions of the beverage manufacturing device 1 . The beverage manufacturing device 1 includes a bean processing device 2 and an extracting 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 the 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 thrown into the extraction container 9 . The fluid supply unit 7 injects 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 extracted coffee liquid is delivered to the cup C as a coffee drink through 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 supplies hot water to the extraction container 9, controls the air pressure in the extraction container 9, and the like. In addition, in this specification, when the air pressure is shown by a number, unless otherwise specified, it means an absolute pressure, and a gauge pressure is the air pressure which made atmospheric pressure into 0 atmosphere. The atmospheric pressure refers to the air pressure around the extraction container 9 or the air pressure of the beverage production device. For example, when the beverage production device is installed at an altitude of 0 m, the international civil aviation organization (= "International Civil Aviation Organization" (abbreviated ICAO)) established in 1976 the reference pressure (1013.25hPa) of the altitude 0 m of the international standard atmosphere (= "International Standard Atmosphere" (abbreviated ISA)).

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 flow.

The fluid supply unit 7 includes a compressor (compressor) 70 as a pressurization source. The compressor 70 compresses and sends out atmospheric air. The compressor 70 is driven by, for example, a motor (not shown) as a driving source. The compressed air sent from the compressor 70 is supplied to an accumulator (air accumulator) 71 via a check valve 71 a. The air pressure in the air tank 71 is monitored by a pressure sensor 71b, and the compressor 70 is driven so as to be maintained at a predetermined air pressure (7 atmospheres (gauge pressure, 6 atmospheres) in this embodiment). The air tank 71 is provided with a drain 71c for draining water, which can drain water generated by compressing the air.

Hot water (water) constituting the coffee drink 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 stored hot water at a predetermined temperature (120 degrees Celsius in this embodiment) based on the detection result of the temperature sensor 72b. The heater 72a is turned ON when the temperature of hot water is 118 degrees Celsius, and turned OFF when it is 120 degrees Celsius, for example.

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 it is detected by the water level sensor 72c that the water level drops below a predetermined water level, water is supplied to the water tank 72 . In the case of this embodiment, tap water is supplied through 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 will be opened to supply water. Once the predetermined water level is reached, the solenoid valve 72d will be closed to cut off the water supply. In this way, the hot water in the water tank 72 is maintained at a certain level. In addition, the water supply to the water tank 72 may be performed every time the hot water used for the production of the coffee drink once is discharged.

The water tank 72 is also provided with a pressure sensor 72g. The pressure sensor 72g detects the air pressure in the water tank 72 . The air pressure in the air tank 71 is supplied to the water tank 72 via a pressure regulating valve 72e and a solenoid valve 72f. The pressure regulating valve 72e decompresses the air pressure supplied from the air tank 71 to a predetermined air pressure. In the case of the present embodiment, the pressure is reduced to 3 atmospheres (gauge pressure, 2 atmospheres). The solenoid valve 72f switches the supply and blocking 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 controlled to open and close so that the air pressure in the water tank 72 is maintained at 3 atmospheric pressure. When supplying tap water to the water tank 72, the air pressure in the water tank 72 is decompressed to a pressure lower than the water pressure of the tap water (for example, less than 2.5 air pressure) by the solenoid valve 72h, so that tap water can be smoothly supplied to the water tank 72 by the water pressure of the tap water. 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 during decompression. In addition, the electromagnetic valve 72h releases the inside of the water tank 72 to the atmosphere when the air pressure in the water tank 72 exceeds 3 atmospheres except when supplying tap water to the water tank 72, and maintains the inside of the water tank 72 at 3 atmospheres.

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. Hot water is supplied to the extraction container 9 by opening the electromagnetic valve 72i, and the supply of hot water is blocked by closing. The amount of hot water supplied to the extraction container 9 can be controlled 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 piping L3 is provided with a temperature sensor 73e for measuring 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 decompresses the air pressure supplied from the air tank 71 to a predetermined air pressure. In the case of the present embodiment, the pressure is reduced to 5 atmospheres (gauge pressure, 4 atmospheres). The solenoid valve 73b switches between 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 increased, the electromagnetic valve 73b will be opened according to the detection result of the pressure sensor 73d, and the inside of the extraction container 9 will be pressurized to a predetermined air pressure (in the case of this embodiment, a maximum of 5 atmospheres (gauge pressure, 4 atmospheres)). The air pressure in the extraction container 9 can be decompressed by the electromagnetic valve 73c. Electromagnetic valve 73c is to switch whether to release the atmosphere in the extraction container 9, and when the pressure is abnormal (for example, when exceeding 5 air pressure in the extraction container 9), the extraction container 9 is released to the atmosphere.

When the production of one coffee drink is completed, in the case of the present embodiment, the inside of the extraction container 9 is washed with tap water. The solenoid valve 73f is opened during washing, and tap water is supplied to the extraction container 9 .

Next, the switching unit 10 will be described. The switching unit 10 is a unit that switches the delivery destination of the liquid sent from the extraction container 9 to either the injection part 10c or the exhaust gas tank T. As shown in FIG. 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 extraction container 9 is dispensed. The coffee drink is poured into the cup C from the pouring part 10c. When discharging the waste liquid (tap water) and residue (ground beans) during washing, 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 cleaning, since residues will pass through the switching valve 10a, it is suitable 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 equipment＞ The bean processing apparatus 2 will be described with reference to FIG. 1 and FIG. 2 . The bean processing device 2 includes a storage device 4 and a crushing device 5 .

＜3-1. Storage device＞ The storage device 4 is a plurality of tanks 40 containing roasted coffee beans. In the case of this embodiment, three tanks 40 are provided. The can 40 includes a cylindrical body 40a for storing roasted coffee beans, and a handle 40b provided on the body 40a, and is configured to be detachable from the beverage production device 1 .

Each canister 40 can accommodate 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 . Different types of roasted coffee beans are, for example, different types of roasted coffee beans. In addition, the so-called different types of roasted coffee beans may be the same type of coffee beans, but the roasted coffee beans have different degrees of roasting. In addition, roasted coffee beans of different types may be roasted coffee beans of different types and degrees of roasting. In addition, at least any one of the three tanks 40 may contain roasted coffee beans mixed with a plurality of types of roasted coffee beans. In this case, the degree of roasting of the roasted coffee beans of each variety may be the same degree.

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

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

Each measuring and conveying device 41 is a collective conveying unit 42 that discharges the roasted coffee beans to the downstream side. The collection conveyance part 42 is comprised by a hollow member, and forms the conveyance path of the roasted coffee beans from each conveyor 41 to the crushing apparatus 5 (especially grinder 5A). The roasted coffee beans discharged from each measuring and conveying device 41 move by their own weight inside the collecting and conveying unit 42 , and flow down to the crushing device 5 .

In the collection conveyance part 42, the guide part 42a is formed in the position corresponding to the bean input opening 103. As shown in FIG. The guide portion 42a forms a passage for guiding the roasted coffee beans input from the bean input port 103 to the crushing device 5 (in particular, the grinder 5A). Thereby, in addition to the roasted coffee beans stored in the tank 40, a coffee drink using the roasted coffee beans input from the bean input port 103 as a raw material can also be produced.

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

Grinders 5A and 5B differ in the particle size of the ground beans. The grinder 5A is a grinder for coarse grinding, and the grinder 5B is a grinder for fine grinding. The grinders 5A and 5B are electric grinders, respectively, and include a motor as a driving source, a rotary blade driven by the motor, and the like. By changing the number of rotations of the rotary blade, the size (grain size) of ground roasted coffee beans can be changed.

The separation device 6 is a mechanism for separating unnecessary substances from the ground beans. The separator 6 includes a passage portion 63 a disposed between the grinder 5A and the grinder 5B. The passage portion 63a is a hollow body forming a separation chamber through which ground beans freely falling from the grinder 5A pass. The passage portion 63a is connected to the passage portion 63b extending in a direction (in the present embodiment, left and right direction) intersecting with the passing direction of the ground beans (in the case of the present embodiment, the vertical direction) and the passage portion 63b is connected to the suction unit 60 . The air in the passage portion 63a is sucked by the suction unit 60, so that light-weight objects such as thin skin and fine powder can be sucked. Thereby, unwanted substances can be separated from 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 the present embodiment, the blower unit 60A is a fan motor, and exhausts the air in the recovery container 60B upward.

The recovery container 60B includes an upper portion 61 and a lower portion 62 that are detachably engaged. The lower part 62 is formed in a bottomed cylindrical shape with an open top, and forms a space for storing unnecessary objects. The upper part 61 is a cover part constituting an opening attached to the lower part 62 . The upper portion 61 includes a cylindrical outer peripheral wall 61a and an exhaust pipe 61b formed coaxially. The blower unit 60A is fixed to the upper part 61 above the exhaust tube 61b so as to suck the air in the exhaust tube 61b. The upper part 61 is a connection passage part 63b. The passage portion 63b is opened on the side of the exhaust tube 61b.

The airflows shown by arrows d1 to d3 in FIG. 4 are generated by driving the air blowing unit 60A. By this airflow, the air containing unnecessary objects is sucked into the recovery container 60B from the passage part 63a through the passage part 63b. Since the passage portion 63b is opened on the side of the exhaust tube 61b, the air containing unnecessary objects circulates around the exhaust tube 61b. 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 part 62). Air is exhausted upward through the inside of the exhaust tube 61b.

A plurality of fins (fin) 61d are integrally formed on the peripheral surface of the exhaust pipe 61b. The plurality of 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 fins 61 , the swirl around the exhaust pipe 61 b of the air containing the unnecessary substances D is promoted.

In the case of the present embodiment, the lower part 62 is formed of a light-transmitting 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 with the cover part 102 (FIG. 2). A manager or a drinker can see unnecessary objects D accumulated in the lower part 62 through the cover part 102 and the peripheral wall of the lower part 62 . It is sometimes easy for the manager to confirm the cleaning timing of the lower part 62, and for the drinker, the expectation of the quality of the coffee drink being produced may be raised by seeing that the unnecessary object D has been removed.

In this way, in this embodiment, the roasted coffee beans supplied from the storage device 4 are first roughly ground by the grinder 5A, and when the coarsely ground coffee beans pass through the passage portion 63a, the unnecessary materials are separated by the separation device 6 . The coarsely ground beans from which unwanted substances have been separated are finely ground by the grinder 5B. Unnecessary substances separated in the separation device 6 are represented by thin skin or fine powder. These may reduce the taste of the coffee drink, but the quality of the coffee drink can be improved by removing the skin and the like from the ground beans.

The crushing of roasted coffee beans is also possible with a grinder (one-stage crushing). However, as in the present embodiment, the particle size of the ground beans can be easily uniformed by the two-stage pulverization of the two grinders 5A, 5B, and the degree of extraction of the coffee liquid can be made constant. When beans are crushed, heat may be generated by friction between a cutter and beans. The two-stage crushing also suppresses heat generation caused by friction during crushing, and prevents deterioration of ground beans (such as flavor loss).

In addition, by going through the stages of rough grinding→separation of unnecessary materials→fine grinding, when separating unnecessary materials such as thin skins, the difference in quality between unnecessary materials and ground beans (necessary parts) can be enlarged. This improves the efficiency of separation of unnecessary substances, and prevents the ground beans (essential part) from being separated as unnecessary substances. In addition, by intervening the separation process of unnecessary matter by suction of air between coarse grinding and fine grinding, heat generation of ground beans can be suppressed by air cooling.

The holding member 820a holds the left and right sides of the container body 90 and exposes the front side of the container body 90 . This makes it easy to recognize the inside of the container body 90 from the front.

Attachment and detachment of the container body 90 to the holding member 820a is performed manually, and the container body 90 is mounted on the holding member 820a by pushing the container body 90 on the holding member 820a toward the rear in the front-rear direction. And, the container body 90 can be separated from the holding member 820a by pulling out the container body 90 toward the front side from the front-rear direction of the holding member 820a.

The pair of shaft members 820b are rods respectively extending in the front-rear direction, and support the holding member 820a. In addition, in this embodiment, the number of shaft members 820b is two, but it may be one, or may be three or more. The holding member 820a is fixed to front end portions of a pair of shaft members 820b. By the mechanism described later, the pair of shaft members 820b advances and retreats in the front-rear direction, whereby the holding member 820a advances and retreats in the front-rear direction, and the container body 90 can be moved in parallel in the front-rear direction. The middle unit 8B can also perform a turning operation to reverse the vertical direction of the extraction container 9 as will be described later.

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

The holding member 801 is also a movable member provided in the supporting member 800 so as to be slidable in the vertical direction. The lift shaft 802 is provided so that the axial direction becomes the up-down direction. The lift shaft 802 penetrates the top of the support member 800 in the vertical direction in an airtight manner, and is provided so as to be able to move up and down freely with respect to the support member 800 .

At the lower end of the lifting shaft 802 is fixed the top of the holding member 801 . The holding member 801 slides in the up and down direction by the lifting and lowering shaft 802, and the holding member 801 can be attached to and detached from the convex portion 911d or the convex portion 901c. In addition, the lid unit 91 can be opened and closed with respect to 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 (without moving up and down) by the driving force of the motor 804a. The lifting shaft 802 can be raised and lowered by the rotation of the nut 804b.

The elevating shaft 802 is a tubular shaft having a through hole in the central axis, and the probe 803 is inserted into the through hole so as to be able to slide up and down. The probe 803 penetrates the top of the holding member 801 in an airtight manner in the vertical direction, and is vertically vertically installed with respect to 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 protrusions 911d, 901c. The valves 913, 903 can be turned from the closed state to the open state by the descent of the probe 803, and can be turned from the open state to the closed state by the rise of the probe 803 (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 with the nut 805b. The upper unit 8A is equipped with a motor 805a, and the nut 805b is set to be rotated at the moment (without 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 operation unit 81C. The operating unit 81C is configured by turning the operating unit 81A upside down, and performs opening and closing operations of the valves 913, 903 provided inside the convex portions 911d, 901c. The operation unit 81C is also configured to open and close the cover unit 91 , but in this embodiment, the operation unit 81C is not used for opening and closing the cover 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 support member 810 is fixedly installed so that its relative position with respect to the frame F does not change, and accommodates the holding member 811 . The support member 810 further includes a communication portion 810 a for communicating the switching valve 10 a of the switching unit 10 with the inside of the support member 810 . The coffee beverage, tap water, and ground bean residue in the container body 90 are introduced into the switching valve 10a through the communication portion 810a.

The holding member 811 has a cylindrical space into which the convex portion 911d of the cover unit 91 or the convex portion 901c of the bottom member 901 is inserted, and has a mechanism for detachably holding them. This mechanism is, for example, an engaging mechanism, which is engaged by a certain pushing force and released by a certain separation force. The coffee beverage, tap water, and ground bean residue in the container body 90 are introduced into the switching valve 10a through the communication portion 810a and the communication hole 811a of the holding member 811 .

The holding member 811 is also a movable member provided in the support member 810 so as to be slidable in the vertical direction. The elevating shaft 812 is provided so that the axial direction becomes the up-down direction. The lift shaft 812 passes through the bottom of the support member 800 in an airtight manner in the vertical direction, and is provided vertically with respect to the support member 810 freely.

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

On the outer peripheral surface of the lift shaft 812, a bolt 812a constituting a lead screw mechanism is formed. 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 (without moving up and down) by the driving force of the motor 814a.

The probe 813 vertically penetrates the bottom of the holding member 811 in an airtight manner, and is vertically vertically installed with respect to the supporting member 810 and the holding member 811 .

The probe 813 is an operating member for opening and closing the valves 913, 903 provided inside the protrusions 911d, 901c. The valves 913, 903 can be changed from the closed state to the open state by the rise of the probe 813, and the valves can be changed from the open state to the closed state by the fall of the probe 813 (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 with the nut 815b. The lower unit 8C is equipped with a motor 815a, and the nut 815b is set to be rotated at the moment (without 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. Middle unit>

The middle unit 8B will be described with reference to FIG. 5 and FIG. 9 . FIG. 9 is a schematic diagram of the middle unit 8B. The middle unit 8B is a support unit 81B including a supporting extraction container 9 . The supporting unit 81B is a unit main body 81B' that includes a locking mechanism 821 in addition to the arm member 820 described above.

The lock mechanism 821 is a mechanism for maintaining the closed state of the lid unit 91 with respect to the container body 90 . The locking mechanism 821 includes a pair of gripping members 821a that sandwich a visor portion 911c of the lid unit 91 and a flange portion 90c of the container body 90 up and down. The pair of grasping members 821 a has a C-shaped cross section fitted between the brim portion 911 c and the flange portion 90 c, and is 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, each gripping member 821a is fitted in such a manner as to sandwich the brim part 911c and the flange part 90c up and down as shown by the solid line in the circled figure of FIG. In this locked state, even if the cover unit 91 is opened by raising the holding member 801 by the elevating shaft 802, the cover unit 91 does not move (the lock is not released). That is, the force of locking by the lock mechanism 821 is set to be stronger than the force of opening the cover unit 91 by the holding member 801 . Thereby, it is possible to prevent the lid unit 91 from being opened to the container body 90 in an abnormal state.

And, when a pair of holding members 821a are in an open state, each holding member 821a will become a state away from the visor part 911c and the flange part 90c as shown by a dotted line in the circled figure of FIG. 9, and the locking of the lid unit 91 and the container body 90 will be released.

The holding member 801 holds the lid unit 91 , and when the holding member 801 is raised from the lowered position to the raised position, the lid unit 91 is separated from the container body 90 when the pair of holding members 821 a are opened. 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 for horizontally moving the arm member 820 in the front-rear direction using the motor 823 as a drive source. Thereby, the container main body 90 supported by the arm member 820 can be moved between the extraction|drawing-out position (state ST1) of a rear side, and the bean insertion position (state ST2) of a front side. The bean input position is a position for inputting ground beans into the container body 90 , and the ground beans ground by the grinder 5B are input from the discharge pipe 5C to the opening 90a of the container body 90 where the cover 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 the position where the container body 90 can be operated by the operation unit 81A and the operation unit 81C, the position coaxial with the probes 803, 813, and the position where the coffee liquid is extracted. The extraction position is a position on the inner side than the bean insertion position. FIG. 5 , FIG. 7 and FIG. 8 all show the situation that the container body 90 is in the withdrawn position. By making the position of the container body 90 different between the input of ground beans, the extraction of coffee liquid, and the supply of water in this way, it is possible to prevent the hot gas generated when coffee liquid is drawn from adhering to the discharge pipe 5C of the supply part of ground beans.

The middle unit 8B further includes a mechanism that uses a motor 824 as a driving source to rotate the supporting unit 81B around a shaft 825 in the front-back direction. Thereby, the posture of the container body 90 (extracted container 9) can be changed from an upright posture (state ST1) with the neck 90b upside down to an inverted posture (state ST3) with the neck 90b downside. Pulling out the rotation of the container 9 is to maintain the state that the cover unit 91 will be locked in the container body 90 by the locking mechanism 821 . In the upright posture and the inverted posture, the upper and lower sides of the drawn container 9 are reversed. In the inverted posture, the convex portion 911d is positioned at the position of the convex portion 901c in the upright posture. In addition, in the inverted posture, the convex portion 901c is positioned at the position of the convex portion 911d in the upright posture. Therefore, in the inverted posture, the operation unit 81A can perform the opening and closing operation of the valve 903 , and the operation unit 81C can perform the opening and closing operation of the valve 913 .

＜5. Control device＞ Referring to Fig. 10, the control device 11 of the beverage production device 1 will be described. FIG. 10 is a block diagram of the control device 11 .

The control device 11 controls the beverage production device 1 as a whole. The control device 11 includes a processing unit 11a, a memory unit 11b, and an I/F (interface) unit 11c. The processing unit 11a is, for example, a processor such as a CPU. The storage unit 11b is, for example, RAM or ROM. The I/F unit 11c includes an I/O interface that performs input and output of signals between an external device and the processing unit 11a. The I/F unit 11c further includes a communication interface capable of performing data communication with the server 16 via a communication network 15 such as the Internet. The server 16 is capable of communicating with a portable terminal device 17 such as a smart phone via the communication network 15 , for example, can receive information such as a beverage making reservation or feedback from the portable terminal device 17 of a drinker.

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

<6. Motion control example>

An example of the control processing of the beverage production apparatus 1 performed 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 production apparatus 1 before a production instruction is referred to as a standby state. The state of each mechanism in the standby state is as follows Like.

The extraction device 3 is in the state of FIG. 5 . The extraction container 9 is in an upright posture and is located at the extraction position. The locking mechanism 821 is in a closed state, and the lid unit 91 locks the opening 90 a of the container body 90 . The holding member 801 is at the lowered position, and is attached to the convex portion 911d. The holding member 811 is in the raised position, and is attached to the convex part 901c. Valves 903 and 913 are in closed state. The switching valve 10a communicates the communication portion 810a of the operation unit 81C with the exhaust gas tank T. As shown in FIG.

In the standby state, if there is an instruction to manufacture a coffee drink, the process of FIG. 11(A) is executed. In S1, a preheating treatment is performed. This process is a process of pouring hot water into the container body 90 to warm the container body 90 in advance. First, the valves 903 and 913 are opened. Thereby, the piping L3, the extraction container 9, and the exhaust gas tank T are brought into a connected state.

The solenoid valve 72i is opened only for a predetermined time (for example, 1500 ms) and then locked. Thereby, hot water is poured into the extraction container 9 from the water tank 72 . 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 the hot water to the exhaust gas tank T is promoted. Through the above processing, the inside of the extraction container 9 and the pipe L2 are preheated, and then the cooling of hot water can be reduced during the production of the coffee beverage.

In S2, the grinding process is performed, in which the roasted coffee beans are pulverized, and the ground beans are put into the container body 90 . First, the lock mechanism 821 is opened, 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 cap 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 input position. Next, the storage device 4 and the crushing device 5 are operated. Thereby, one 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 unwanted objects are separated by the separating device 6 . 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 to attach the lid unit 91 to the container body 90 . The locking 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 an open state, and the valve 913 is in a closed state.

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

In S11 , a smaller amount of hot water than one cup of hot water is poured into the extraction container 9 in order to steam the ground beans in the extraction container 9 . Here, the solenoid valve 72i is opened for a predetermined time (for example, 500 ms) to be closed. Thereby, hot water is poured into the extraction container 9 from the water tank 72 . Then, it waits for a predetermined time (for example, 5000 ms) to end the process of S11. The ground beans can be steamed by this treatment. By steaming the ground beans, the carbon dioxide gas contained in the ground beans can be released, which improves the extraction effect afterwards.

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

By the process of S12, the inside of the extraction container 9 can be brought into a state where one atmospheric pressure exceeds 100 degrees Celsius (for example, about 110 degrees Celsius). Next, the inside of the extraction container 9 is pressurized in S13. Here, the electromagnetic 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 a non-boiling air pressure (for example, 4 atmospheres (gauge pressure, 3 atmospheres)). Then, the valve 903 is set to a closed state.

Next, this state is maintained for a predetermined time (for example, 7000 ms) to perform immersion-type coffee liquid extraction (S14). Thereby, extraction of the immersion-type coffee liquid under high temperature and high pressure is carried out. Immersion extraction under high temperature and high pressure can expect 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 the coffee liquid can be accelerated. Second, by creating a high temperature, the extraction of the coffee liquid will be accelerated. Third, by creating a high temperature that reduces the viscosity of the oil contained in the ground beans, the extraction of the oil is facilitated. Thereby, coffee drinks with high aroma can be manufactured.

The temperature of the hot water (high temperature water) only needs to exceed 100 degrees Celsius, but a higher temperature is advantageous at the point of extraction of the coffee liquid. On the other hand, in order to raise the temperature of hot water, the cost generally becomes high. Therefore, the temperature of the hot water may be, for example, 105 degrees Celsius or higher, or 110 degrees Celsius or higher, or 115 degrees Celsius or higher, and may be, 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 inside of the extraction container 9 is decompressed. 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 opened, and the solenoid valve 73c is opened for a predetermined time (for example, 1000 ms) to be closed. It will be released to the atmosphere in the extraction container 9 . Then, the valve 913 is closed 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 at once. The hot water in the extraction container 9, the ground beans are explosively scattered in the extraction container 9. Thereby, hot water can be boiled uniformly. In addition, the destruction of the cell wall of the ground beans can be accelerated, and the subsequent extraction of the coffee liquid can be further accelerated. Moreover, the ground beans and hot water can also be stirred by this boiling, so the extraction of the coffee liquid can be accelerated. In this way, in this embodiment, the extraction efficiency of the coffee liquid can be improved.

In S16, the drawn 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. Also, 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, respectively. When the container 9 is taken out in an inverted posture, the neck 90b or the lid unit 91 will be located on the lower side.

In S17, the through-type coffee liquid is extracted, and the coffee beverage is delivered to the cup C. Here, the switching valve 10a is switched so that the injection part 10c communicates with the communication part 810a of the operation unit 81C. And, both the valves 903 and 913 are opened. Furthermore, the electromagnetic valve 73b is opened for a predetermined time (for example, 10000 ms) to form a predetermined air pressure (for example, 1.7 atmospheric pressure (gauge pressure, 0.7 atmospheric pressure)) in the extraction container 9 . In the extraction container 9 , the coffee drink in which the coffee liquid is dissolved in hot water passes through the filter provided in the cover unit 91 and is delivered to the cup C. The filter is to limit the leakage of the residue of the grinding beans. The extracting process is completed by the above.

In this embodiment, the extraction efficiency of the coffee liquid can be improved by combining the immersion-type extraction in S14 and the permeable extraction in S17. In the state where the extraction container 9 is an upright posture, the grinder will reach from the waist 90e to the Up to the bottom 90f and piled up. On the other hand, when the extraction container 9 is in an upside-down 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 that of the neck 90b, and the piled thickness of the ground beans in the inverted posture is thicker than that in the upright posture. That is, the ground beans are relatively thin and widely piled when the extraction container 9 is in an upright posture, and relatively thick and narrowly piled up in an upside-down posture.

In the case of this embodiment, since the immersion extraction in S14 is performed with the extraction container 9 in an upright posture, hot water can be brought into contact with the ground beans in a wide range, and the extraction efficiency of the coffee liquid can be improved. However, in this case, the hot water and the ground beans tend to come into partial contact. On the other hand, the permeable extraction in S17 is performed with the extraction container 9 in an inverted posture, so hot water passes through the accumulated grinds while contacting more grinds. The hot water will be in contact with the ground beans everywhere, which can improve the extraction efficiency of the coffee liquid.

Returning to FIG. 11(A), the extraction process in S3 is followed by the discharge process in S4. Here, processing related to cleaning the inside of 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 coffee beverage production process is completed. Thereafter, the same process will be repeated per manufacturing instructions. The time required to manufacture one coffee drink is, for example, about 60 to 90 seconds.

<7. Outline of device configuration>

As mentioned above, the beverage manufacturing device 1 includes a bean processing device 2 and an extracting device 3 as a manufacturing unit. In more detail, the bean processing device 2 includes a storage device 4 and a crushing device 5, and the extracting device 3 includes a fluid supply unit 7, a driving unit 8, an extracting container 9, and a switching unit 10 (see FIGS. 2 and 3 ). The grinding device 5 receives a cup of roasted coffee beans from the storage device 4, and grinds the beans in two stages by the grinders 5A and 5B. At this time, unnecessary materials such as skins are separated from the ground beans by the separation device 6 . After the ground beans are put into the extraction container 9, a cup of beverage is provided through the injection of hot water into the extraction container 9 by the fluid supply unit 7, the reversal of the posture of the extraction container 9 by the drive unit 8, the delivery of liquid from the extraction container 9 to the cup C by the switching unit 10, and the like.

A part of the above-mentioned manufacturing unit is covered by the cover part 102 which is entirely constituted as a transparent cover, so that users (such as managers of the device 1, drinkers, etc.) can see from the outside of the device 1. In the present embodiment, among the above-mentioned manufacturing parts, a part of the plurality of tanks (canister) 40 of the storage device 4 is exposed, and other elements are substantially housed in the housing (housing) 100, but all of the manufacturing parts may be housed in the housing 100 as another embodiment. In other words, what is necessary is just to make cover part 102 cover at least a part of a manufacturing part.

At least a part of the production part is covered visibly from the outside of the device 1 by the cover part 102. For example, when the user is a manager of the device 1, the manager may sometimes check the operation of the device together with preparations for making beverages. When the user is a purchaser of the beverage, the purchaser may wait until the preparation of the beverage is completed while increasing the sense of expectation for the beverage. For example, the extraction container 9 of the extraction device 3 can be viewed from the outside of the device 1 through the cover portion 102, and the extraction process that is of high interest to the user can be observed among several processes of beverage production. The drive unit 8 functions as a posture changing unit that changes the posture of the extraction container 9, and the extraction container 9 is a movable part that can be turned upside down in the manufacturing department as described above. Therefore, sometimes the reverse action of extracting the container 9 is more likely to arouse the user's interest, and the user can observe this, which can make the user enjoy it.

On the other hand, in order to further improve the quality of beverages provided by the beverage production device 1, for example, improvement of the manufacturing process, improvement of various side surfaces such as the configuration surface and the control surface of the device 1 for realizing the improvement of the manufacturing process are also required. As an example, it is possible to change some elements included in the device 1 . Hereinafter, referring to FIGS. 12 to 14 , an example of the liquid delivery volume adjusting device 720 that can function as the water tank 72 in FIG. 3 will be described.

<8. Configuration example of liquid delivery volume adjustment device> FIG. 12 is a schematic diagram showing a liquid delivery volume adjustment device 720 . 13 is a cross-sectional view taken along line IV-IV in FIG. 12 and a cross-sectional view showing another example (configuration example EX31). The feeding amount adjusting device 720 is a tank that stores hot water (water) constituting the coffee drink, similarly to the water tank 72, and has a function of sending out a certain amount of hot water. Thereby, hot water necessary for a cup of coffee beverage can be delivered sequentially, and the amount of hot water at that time can also be changed. In the following description, the same symbols are assigned to the configurations having the same functions as those related to the water tank 72 .

The liquid feeding amount adjusting 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 sectional view of FIG. 13, the groove 720a has a cylindrical shape as a whole. A partition wall 722 is provided in the groove 720a, and the internal space thereof is divided into an outer cylindrical space 725 and an inner cylindrical space 726A by the partition wall 722 . In the case of this embodiment, the partition wall 722 is a cylindrical wall body arranged concentrically with the peripheral wall 721 , but the partition wall 722 may be eccentric to the peripheral wall 721 as shown in configuration example EX31 of FIG. 13 .

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

In the storage part 725, the heater 72a which heats the water in the storage part 725, and the temperature sensor 72b which measures the temperature of water are provided. The heater 72a maintains the temperature of the stored hot water at a predetermined temperature (120 degrees Celsius in this embodiment) based on the detection result of the temperature sensor 72b. The heater 72a is turned ON when the temperature of hot water is 118 degrees Celsius, and turned OFF when it is 120 degrees Celsius, for example.

The portion of the upper wall 723 that defines the storage portion 725 is a pipe for connecting the air pressure supplied to the tank 71 (see FIG. 3 ), and a solenoid valve 72f is provided here. The liquid delivery volume regulator 720 is equipped with a sensor (not shown, such as a sensor corresponding to the pressure sensor 72g in FIG. 3 ) that detects the air pressure in the storage part 725. The solenoid valve 72f switches the supply and blocking of the air pressure regulated by the pressure regulating valve 72e (see FIG. 3 ) to the storage part 725. The solenoid valve 72f is controlled to open and close so that the air pressure in the storage part 725 is maintained at 3 atmospheric pressure when the water supply to the storage part 725 is excluded.

The portion of the upper wall 723 that defines 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 supplying the tap water to the storage part 725, the air pressure of the storage part 725 is decompressed to less than 2.5 atmospheres by the solenoid valve 72h so that the tap water can be smoothly supplied to the storage part 725 by the hydraulic pressure of the water. 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 part 725 to the atmosphere during decompression. In addition, the electromagnetic valve 72h releases the storage part 725 to the atmosphere when the air pressure in the storage part 725 exceeds 3 atmospheric pressure, and maintains the storage part 725 at 3 atmospheric pressure, except when supplying water to the storage part 725.

In the bottom wall 724, the portion defining the storage portion 725 is connected to the pipe L2 that supplies tap water to the storage portion 725, and the solenoid valve 72d is provided here. The solenoid valve 72d is controlled to open and close 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 .

The part of the bottom wall 724 that defines the storage part 725 is also connected to the pipe L2' that discharges the hot water in the storage part 725, and a solenoid valve 72d' is provided here. The solenoid valve 72d' is opened when the hot water in the storage part 725 is discarded, and the hot water in the storage part 725 is discharged to the pipe L2'.

The storage part 726 is a space whose volume can be changed by the movement of the movable member 727c. The storage part 726 is supplied with hot water from the storage part 725 via the piping 728a, the electromagnetic valve 728, and the piping 728b. The pipe 728 a connects between the portion of the bottom wall 724 that defines the storage portion 725 and the electromagnetic valve 728 . The pipe 728 b connects between the portion of the bottom wall 724 that defines the storage portion 726 and the electromagnetic valve 728 .

In the example of FIG. 12 , the solenoid valve 728 is a three-way valve, and can switch between connecting and blocking the piping 728b and the piping 728a, and switching between connecting and blocking the piping 728b and the piping 728c. In addition, the solenoid valve 728 can block any one of the pipes. The pipe 728c is a pipe for sending the hot water in the storage unit 726 to the extraction container 9 .

By switching the communication and blocking between the piping 728b and the piping 728a, the connection and blocking between the storage part 725 and the storage part 726 can be switched. By switching the communication and blocking between the piping 728b and the piping 728c, the sending and storage of the hot water in the storage unit 726 can be switched.

The solenoid valve 728 blocks the piping 728b and the piping 728c when the piping 728b and the piping 728a are connected. Conversely, when the piping 728b and the piping 728c are connected, the piping 728b and the piping 728a are blocked. The arrow shown in the solenoid valve 728 in the figure shows the operating state of the solenoid valve 728. In the case of the example in FIG.

In addition, in this case, the electromagnetic valve 728 is configured as a three-way valve, so that these switches can be performed by one electromagnetic valve 728 . However, the piping 728b may be divided into two, and a valve for switching between the connection and blocking between the piping 728b and the piping 728a and a valve for switching between connecting and blocking between the piping 728b and the piping 728c may be provided.

The liquid delivery volume adjustment device 720 includes a drive unit 727 . The drive unit 727 controls the volume of the storage unit 726 according to the amount of hot water delivered from the storage unit 726 . Depending on the size of the coffee cup, the amount of hot water required for one cup varies. The driving unit 727 adjusts the volume of the storage part 726 so that an appropriate amount of hot water is sent from the storage part 726 corresponding to the size of the coffee cup.

The drive unit 727 is a mechanism that changes the volume of the storage unit 726 by moving the movable member 727c up and down. The movable member 727c is a piston-shaped member configured to be inserted into the space 726A and slide in the vertical direction, and its bottom surface 727d constitutes an upper wall of the storage portion 726 . From this point of view, the movable member 727c may be called a piston unit or the like, and the space 726A may also be called a cylinder unit or the like. The volume of the storage part 726 is changed by raising and lowering the bottom surface 727d.

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 727 c 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 there is a gap between the groove 727e and the inner surface of the partition wall 722 .

The 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 above the highest water level of hot water in the storage part 725 (position of a sensor 731b described later), and serves as an air communication part that communicates the storage part 725 with the space 726A. The air communicates between the storage part 725 and the storage part 726 through the opening 722a and the groove 727e, and the air pressure in these spaces becomes the same. In addition, when the storage parts 725 and 726 are always set at atmospheric pressure, passages leading to the atmosphere may be individually provided.

The driving unit 727 is a moving mechanism including a motor 727a supported on the upper wall 723 as a driving source, and a screw shaft 727b as a moving movable member 727c. The screw shaft 727b is extended in the vertical direction, and is rotated by the driving force of the motor 727a. The movable member 727c has a screw hole 727f opened thereon, and the screw shaft 727b is engaged with the screw hole 727f. The movable member 727c is given a backstop (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 vertical direction provided on the inner surface of the partition wall 722 and the peripheral surface of the movable member 727c.

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

The water level sensor 72c is a measurement means for measuring the water level of the hot water in the storage part 725 . The water level sensor 72c includes: a hollow cylindrical storage part 729 extending up and down, a float 730 disposed in the storage part 729, a sensor 731a for detecting the lower side of the float 730, and a sensor 731b for the upper side.

The storage part 729 communicates with the storage part 725 through the communication part 729a located below the sensor 731a, and communicates with the storage part 725 through the communication part 729b located above the sensor 731b. The hot water in the storage part 725 flows into the storage part 729 through the communication part 729a. The communication portion 729 b is an air communication portion that communicates the storage portion 725 and the storage portion 729 , and air communicates between the storage portion 725 and the storage portion 729 via the communication portion 729 b. Therefore, the water level of the hot water in the storage part 729 is equal to the water level of the hot water in the storage part 725 .

In this example, the storage portion 729 is formed of a transparent member such as glass or acrylic. Thereby, the water level of the hot water in the storage part 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 part 725 . Of course, a permeable portion may be provided in a part of the peripheral wall (721) of the storage portion 725 so that the water level thereof can be seen.

The buoy 730 may be anything as long as it floats on the hot water in the storage part 729 .

The sensors 731 a and 731 b are, for example, photosensors (photointerrupters), and detect the float 730 from the outside of the storage part 729 . When 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 731 a 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 at a position higher than the heater 72a, so that empty heating of the heater 72a can be prevented.

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

A configuration equivalent to that of the water level sensor 72c may also be constructed inside the storage portion 725 . However, as in this example, by constructing the water level sensor 72c outside the storage part 725, it is easy to confirm the water level of the storage part 725 from the outside.

Next, an example of the operation of the liquid delivery volume adjusting device 720 will be described with reference to FIG. 14 . First, the volume of the storage portion 726 is adjusted by the driving unit 727 according to the size of the cup or the like. The state ST61 shows its state. In the example of the figure, the movable member 727c is lowered, and the volume of the storage part 726 is set to be smaller than that of the example of FIG. 13 . The solenoid valve 728 communicates with the pipe 728b and the pipe 728c, and hot water is not supplied from the storage part 725 to the storage part 726 .

Once the volume of the storage portion 726 is set, the drive unit 727 is stopped, and the pipe 728b communicates with the pipe 728a through the solenoid valve 728 . The storage part 725 and the storage part 726 have the same air pressure, and the storage part 726 is located on the bottom side of the groove 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 minimum water level of the hot water in the storage part 725 (position of the sensor 731a), a head difference always occurs between the storage part 725 and the storage part 726 (the hot water in the storage part 725 is high). Therefore, hot water is supplied from the storage part 725 to the storage part 726 until the storage part 726 is full. The state ST62 is a state indicating that the storage unit 726 is full. Hot water also enters the groove 727e, but the volume of the groove 727e is sufficient to ensure communication of air, and can be set to a very small amount.

In the case of this example, the heater 72a is not provided in the storage part 726, but the storage part 726 is surrounded by the storage part 725, so the heat retention performance of the stored hot water can be ensured. In addition, it can also be driven in state ST62 by The unit 727 is used to change the volume of the storage part 726.

The supply of hot water from the storage part 725 to the storage part 726 is also possible in other ways, but in this example, by utilizing the head difference between the storage part 725 and the storage part 726, hot water can be supplied with a relatively simple structure.

Next, the hot water stored in the storage unit 726 is sent out. As shown in state ST63, the pipe 728b communicates with the pipe 728c by the solenoid valve 728, and 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 part 726. After the start of hot water delivery, any one of the pipes also shuts off the operation state of the solenoid valve 728, and the hot water in the storage part 726 can also be sent out step by step. For example, for the steaming process (S11 of FIG. 11(B)), the hot water supply may be interrupted, and then the process of sending the remaining hot water may be performed (S12 of FIG. 11(B)).

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

According to the above example, the delivery amount of hot water can be adjusted. The adjustment of the delivery amount of the liquid is generally controlled by using 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, there may be cases where the corresponding flow sensor is not commercially available or is expensive. In contrast, according to the above example, by adjusting the volume of the storage portion 726 , it is possible to adjust the delivery amount of hot water without a flow sensor.

<9. Example of operation control when using liquid delivery volume adjustment device> By using the liquid delivery amount adjusting device 720 described above, 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, an example of the control processing of the device 1 executed by the processing unit 11 a (see FIG. 10 ) of the control device 11 will be described with reference to FIG. 15 . 11(A) and FIG. 11(B) and the operation content of the liquid delivery volume adjusting device 720 in FIGS. 12 to 14 may be referred to for descriptions omitted below.

Fig. 15 shows an example of control related to one coffee beverage production operation. First, preheating S1 is divided into at least two heating processes S101 and S102 (in order 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 ) to warm the extraction container 9 in advance. First, the solenoid valve 728 is controlled so that the pipe 728 a and the pipe 728 b communicate with each other, and a small amount of hot water is moved from the storage part 725 to the storage part 726 . Then, the solenoid valve 728 is controlled so that the pipe 728b communicates with the pipe 728c, and the hot water in the storage part 726 is sent out to the extraction container 9 through 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 disposal tank T. FIG.

The inside of the extraction container 9 and the pipes L2 to L3 are preheated in S101 to prevent the hot water from becoming cold during the beverage production in each process described later. In addition, by performing S101, it may be possible to flush away residues (residues of liquid, etc.) in the flow path generated during previous or past extractions.

S102 is a process of supplying the steam generated in the storage parts 725 and 726 into the container main body 90 to heat the extraction container 9 . This steam can be generated by boiling the hot water in the storage parts 725 and 726 by reducing the pressure in the storage parts 725 and 726, and can be realized by the same procedure as S15 (refer to FIG. 11(B)). After the supply of steam to the extraction container 9 or the heating of the extraction container 9 using the steam is completed, the solenoid valve 728 is controlled to block the piping 728b and the piping 728c.

By performing S102, the whole extraction container 9 can be uniformly heated. Thereby, a non-uniform extraction of liquid, for example from ground beans, can be performed at a desired temperature, resulting in an improved quality of the drink. In addition, in S102, the pressure of the storage parts 725 and 726 drops, and the liquid therein starts to boil, so the liquid can be stirred to make the temperature uniform.

Incidentally, the piping L3 which functions as a connecting portion connecting the storage portions 725 and 726 and the extraction container 9 and forms a flow path therebetween 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 mentioned above, the extraction container 9 has valves 903 and 913, which function as inlets or outlets for the hot water and steam used for the liquid used in the above-mentioned extraction, and the steam is used for heating the beverage liquid obtained by the above-mentioned extraction (coffee liquid in this example) or S102. In this example, in S102 , steam flows into the extraction container 9 from the valve 913 and flows out of the extraction container 9 through the valve 903 . When the 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, and can flow out of the extraction container 9 from the valve 903. According to this aspect, for example, when a drink is manufactured through various processes described later, the taste, flavor, etc. of the drink will not be unintentionally thinned, which contributes to the improvement of the quality of the drink.

Alternatively, after the extraction container 9 is filled with steam, the extraction container 9 may be vibrated with both valves 903 and 913 closed. Vibration to the extraction container 9 can be realized by the motors 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 expands uniformly in the extraction container 9, and the entire extraction container 9 can be uniformly heated.

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

After preheating S1' is performed as above, S2 is performed in the same procedure as in FIG. 11(A), followed by extraction processing (in order to distinguish it from S3 in FIG. 11(A), it is referred to as S3'). In the extracting process S3', the hot water injection S12 for main extraction is divided into at least two hot water injection processes S121 and S122. S121 of injecting hot water for the first time is performed after S11 and before S13. Then, S13 to S16 are performed in the same procedure as in FIG. 11(B).

Here, in S14, the ground beans to be extracted are deposited in the extraction container 9 in an upright position 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, and S122 of injecting hot water for the second time is performed after S17 or together with S17.

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

As mentioned above, when the extraction container 9 is in an upright posture, the ground beans are accumulated from the waist 90e to the bottom 90f, and on the other hand, when the extraction container 9 is in an inverted posture, the ground beans are accumulated from the shoulder 90d to the neck 90b. That is, the extraction container 9 includes a thick part from the waist 90e to the bottom 90f and a thin part from the shoulder 90d to the neck 90b, and the ground beans are accumulated in the thick part in the upright posture and in the thin part in the inverted posture.

During the permeable extraction in S17 above, since the extraction container 9 is in an upright position, the hot water in the extraction container 9 is in contact with the ground beans through thicker and accumulated ground beans than in the upright position, so that the efficiency of the permeable extraction can be realized. Here, S122 of the second injection of hot water is performed together with S17, so the extraction container 9 additionally receives hot water in S122 while delivering the beverage obtained by immersing the hot water received in S121. Moreover, the hot water that additionally flows into the extraction container 9 through S122 is essentially not used for immersion extraction, but is mainly used for permeation extraction. According to such an extraction form, the unique flavor of permeable extraction can be effectively imparted to beverages, and the quality of beverages 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, for example, by the user, that is, the ratio of submerged extraction and permeable extraction can be adjusted. Thereby, it is possible to manufacture a beverage with a quality corresponding to the user's preference.

16(a) to 16(h) and 17(i) to 17(o) are schematic diagrams for explaining how the control form of the liquid delivery volume adjusting device 720 corresponds to each step of the above-mentioned FIG. 15 . For ease of understanding, in the following description, it is assumed that the simple mode using the liquid delivery volume adjustment device 720 is used, and the solenoid valve 728 of the three-way valve is divided into: a valve 7281 for switching the communication and blocking of the piping 728a and the piping 728b, and a valve 7282 for switching the communication and blocking of the piping 728b and the piping 728c.

FIG. 16( a ) shows the initial state of the liquid delivery volume adjustment device 720 , and the beverage production device 1 is waiting for an instruction to start production of the beverage. In the initial state, as schematically shown in the figure, both valves 7281 and 7282 are closed.

16( b ) to 16( c ) show the form of the liquid delivery volume adjusting device 720 corresponding to the above-mentioned S101 (heat 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, and a small amount of hot water is moved from the storage part 725 to the storage part 726 as shown by the dotted arrow. Next, after the valve 7281 is closed, the valve 7282 is opened in the process of FIG. Thereby, the inside of the extraction container 9 and the pipes L2 to L3 are heated.

FIGS. 16( d ) to 16 ( e ) show the form of the liquid delivery amount adjusting device 720 corresponding to the above-mentioned S102 (heat treatment of the extraction container 9 by steam). In the process of FIG. 16( d ), steam is generated in the storage parts 725 and 726 by reducing the pressure in the storage parts 725 and 726 to boil the hot water in the storage parts 725 and 726 . Since the valve 7282 is in an open state, the generated vapor is supplied to the extraction container 9 through the pipe 728c as shown by a dotted arrow. And, in the project of Fig. 16 (d), also can stir the hot water in storage part 725 and 726 by above-mentioned boiling, when the temperature of this stirred hot water does not reach predetermined value (such as 118 degrees Celsius), heater 72a (referring to Fig. 12) can be driven. Then, in the process of FIG. 16( e ), the valve 7282 is closed to stop the supply of steam to the extraction container 9 . Thereby, the whole extraction container 9 is heated uniformly.

Fig. 16(f) to Fig. 16(h) show the form of the liquid delivery volume adjusting device 720 corresponding to the preparation process for carrying out the extraction process S3'. In the process of FIG. 16(f), after returning to 3 atmospheric pressure in the storage parts 725 and 726, in the process of FIG. After the transfer of 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 one cup can also be preset or selected by the user, or can also be determined according to the size of the cup placed on the placement portion 110, or can be a fixed value. Although not shown here, the grinding process S2 may be performed in parallel between the processes of FIG. 16( f ) to FIG. 16( h ), thereby shortening the time until the production of the beverage is completed.

Fig. 17(i) to Fig. 17(j) show the form of the liquid supply adjusting device 720 corresponding to the injection hot water S11 for steaming. In the process of FIG. 17( i ), the valve 7282 is opened, and after a predetermined time elapses, the process of FIG. 17( j ) closes the valve 7282 . Thereby, a part (about 30 cc, for example) of the hot water stored in the storage part 726 flows into the extraction container 9 for steaming in S11 as shown by the dotted arrow.

17( k ) to 17 ( l ) show the form of the liquid delivery amount adjusting device 720 corresponding to the first injection hot water S121 for main extraction. After steaming of the ground beans is completed, the valve 7282 is opened in the process of FIG. 17( k ), and after a predetermined time elapses, 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 part 726 flows into the extraction container 9 as shown by a dotted arrow.

Although not shown here, S13-S17 are performed after the process of FIG. 17(l). The details will be described later, but in S13 of this example, injection of hot water (about 30 cc, for example) is performed together with pressurization in the pumping container 9 .

FIG. 17( m ) shows the form of the liquid delivery amount adjusting device 720 corresponding to the injection hot water S122 for the second main extraction. By opening the valve 7282 in the process of FIG. 17( m ), the remaining hot water (for example, about 80 cc) in the storage part 726 will additionally flow into the extraction container 9 as shown by the dotted arrow. As mentioned above, S122 is performed approximately simultaneously with S17, and the hot water flowing into the extraction container 9 here is not substantially used for immersion extraction, but is mainly used for permeation extraction.

Then, substantially all of the beverage is delivered from the extraction container 9 to the cup to complete S17. Here, after S122 and before S17 is completed, the delivery of beverages can be promoted by using the steam in the storage parts 725 and 726 and the air pressure from the compressor 70 concomitantly. The steam in the storage parts 725 and 726 can be generated in the same procedure as S102 (the processes of FIG. 16( d ) to FIG. 16( e )). That is, in the process of FIG. 17(n), the inside of the storage parts 725 and 726 is decompressed to boil hot water, thereby generating steam in the storage parts 725 and 726, and the steam is supplied to the extraction container 9 through the pipe 728c. At this time, like the process of FIG. 16( d ), the hot water in the storage parts 725 and 726 is properly 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 accelerated, the inside of the extraction container 9 is adjusted to, for example, about 1.6 to 2 atmospheres.

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 (S11, etc.) corresponding to the periods T1 to T11 are displayed together with the periods T1 to T11. The vertical axis represents the air pressure P in the extraction container 9 for each period T1 to T11.

The periods T1 to T2 are periods corresponding to the hot water injection S11 for steaming. During 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 within the period T1, but may be preset or selected by the user, or may be changed according to the type of drink. Then, use this hot water to steam the ground beans. Let this period (about 15 seconds) be period T2.

Period T3 is a period corresponding to the first injection of hot water S121. During period T3, the inside of the extraction container 9 is pressurized to 3 atmospheres, and hot water (about 40 cc) for actual 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 . During period T4, the inside of the extraction container 9 is pressurized to 5 atmospheres, and hot water (about 30 cc) is flowed into the extraction container 9 .

Here, the amount of injected hot water can be adjusted between periods T3 and T4. For example, the injected hot water of about 70 cc can be completed in period T3. The points of injecting hot water while pressurizing the inside of the extraction container 9 are common to both periods T3 and T4 , but in this example, the pressurization forms are different from each other. For example, during the pressurization period T3~T4, the form of pressurization becomes gentle on the way (around 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 or even adjusting the pressurization form during the period T3~T4, the range of taste, flavor, etc. that can be expressed can sometimes be expanded for the beverage liquid obtained in the submerged extraction S14 of the subsequent process.

The period T5 is a period corresponding to the submerged extraction S14. After reaching 5 atmospheric pressure in the extraction container 9, maintain its state. Let this period (about 1 second) be period T5. Thereby, the coffee liquid of the beverage liquid is extracted from the ground beans to be extracted.

The period T6 to T8 is a period corresponding to the depressurization S15 in the extraction container 9 . During the period T6 to T7, the above-described depressurization is divided into two stages and performed. In the period T6, first, the inside of the extraction container 9 is decompressed from 5 atmospheres to 1.5 atmospheres (sudden decompression) in a relatively short time, and then stands by for a predetermined period (about 3 seconds). Next, during the period T7, the inside of the pumping container 9 is decompressed to 1 atmosphere, and then it stands by for a predetermined period (about 1 second).

As mentioned above, the liquid in the extraction container 9 is boiled and stirred by decompression S15. According to the decompression form of this example, first, a part of the liquid in the extraction container 9 will be boiled and stirred by the decompression of the first stage during the period T6, and then other parts of the liquid in the extraction container 9 can also be boiled and stirred by the decompression of the second stage during the period T7. Therefore, for example, stirring of the entire liquid in the extraction container 9 can be appropriately performed, which is sometimes advantageous when, for example, there is unevenness in concentration or composition in the extracted beverage liquid. Then, during the period T8, the inside of the extraction container 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 container 9.

The period T9 is a standby period (about 2 seconds) after the reversing S16 of extracting the container 9 and thereafter. In addition, the timing of the start of the period T9 corresponds to the timing when the above-mentioned inversion S16 is performed. In the period T9, in the extraction container 9 reversed at S16, the ground beans to be extracted are deposited relatively thickly in the lower part of the extraction container 9 . And, in the period T9, the inside of the extraction container 9 is depressurized to 1 atmosphere.

The period T10~T11 is a period corresponding to the permeable extraction S17, whereby the beverage is delivered from the extraction container 9 to the cup. As mentioned above, the second injection of hot water S122 is performed approximately simultaneously with S17, whereby the hot water (about 80 cc) that additionally flows into the extraction container 9 is mainly used for permeable extraction.

In this example, after S122 in the period T10, the inside of the extraction container 9 is pressurized to 1.6 atmospheres, and in the subsequent period T11, the inside of the extraction container 9 is pressurized to 2 atmospheres to promote delivery of the beverage. In the period T10, the delivery of the beverage is promoted by the steam of the storage parts 725 and 726, and in the period T11, the delivery of the beverage is promoted by the air pressure from the compressor 70. Thereby, all of the beverage to be dispensed (including the liquid in the flow path) can be supplied to the cup appropriately and in a relatively short time. FIG. 19 is a waveform showing the amount of hot water in the extraction container 9 that changes with the passage of time (how the amount of hot water changes) with dashed lines added to FIG. 18 . In this example, a total of about 185cc of beverage would be served.

In more detail, each period T1 and the like described above are associated with each step of S11 and the like or its sub-steps, and are assembled as follows. that is, Period T1: hot water injection process for steaming, Period T2: stuffy steaming project, Period T3: The first hot water injection process, Period T4: Pressurization works, Period T5: high pressure impregnation works, Period T6: Rapid decompression process after high-pressure immersion, or atmospheric release process (first half) to release the inside of the extraction vessel 9 to the atmosphere, Period T7: Rapid depressurization process after the standby state, or atmospheric release process (second half) to release the inside of the extraction container 9 to the atmosphere, Period T8: Standby process waiting for the liquid remaining in the flow path to flow into the extraction container 9, Period T9: container posture change process (container inversion process), and waiting for the accumulation of the extraction object in the extraction container 9 to be completed, Period T10: The second hot water injection process, drink delivery process (first half), or drink delivery promotion process using steam, Period T11: beverage dispensing process (second half), or beverage dispensing promotion process 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 can also be additionally plotted on the information display device 12 (see FIG. 1, etc.). Thereby, when the user is a purchaser of a drink, etc., the user may not get tired of waiting. In addition, when the user is a manager of the device 1 or the like, the user can sometimes confirm whether or not the production of the drink by the device 1 is properly performed.

FIG. 20 shows how the actual values of the air pressure and the amount of hot water in the extraction container 9 are superimposed (in real time) on the above-mentioned target values and plotted together with time, as information that can be displayed on the information display device 12 during beverage production. That is, FIG. 20 is a waveform showing the change of the actual value of the air pressure in the extraction container 9 and the amount of hot water added to FIG. 19 . These actual values can be respectively measured by the pressure sensor and the temperature sensor as actual measured values. In the figure, the solid line shows the change form of the target value of the air pressure in the extraction container 9 when a cup of beverage is drawn, and the dotted line shows the change form of the actual measured value of the air pressure in the extraction container 9 . In addition, the dotted line shows the change form of the target value of the amount of hot water in the extraction container 9 , and the two-dot hatch line shows the change form of the actual measurement value of the amount of hot water in the extraction container 9 .

The example in FIG. 20 shows that the process at the present time 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 plotted from the period T1 to this time point (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-mentioned actual measurement values will continue to be plotted in subsequent processes. According to such a display form, when the actual measurement value does not reach the target value or the actual measurement value deviates greatly from the target value, the user can quickly respond to the occurrence of leakage in the flow path, or the condition of each element forming the flow path (pipes, valves, etc.).

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

The pattern of change of the above-mentioned target value of the air pressure in the extraction container 9 and the amount of hot water is prepared in advance as a plurality of patterns, and the user can select from among them the pattern corresponding to the fan. The information representing the above-mentioned plurality of samples may be stored in advance in the memory unit 11 b (see FIG. 10 ), for example, or may be obtained from the server 16 via the communication network 15 . Moreover, the above selection by the user can be realized by the information display device 12 of the touch panel display.

In addition, when extracting a cup of beverage, changes in the above-mentioned target value and actual measurement value of the air pressure and the amount of hot water in the extraction container 9 are displayed on the information display device 12 throughout the period T1 to T11, indicating that such information can be stored in the memory unit 11b, for example. Therefore, the user can also perform a predetermined operation through the information display device 12 according to the need, so that the information can be displayed again. Thereby, a user can also confirm the change of the said target value and the actual measurement value at the time of beverage manufacture performed in the past, for example.

In addition, the periods T1 to T11 are schematically shown with equal lengths in all of FIGS. 18 to 20 , but these may be displayed on the actual information display device 12 at intervals corresponding to the actual time.

As described above, according to the present embodiment, in S102 of the preheating process S1', the pumping container 9 is heated by the steam generated in the storage parts 725 and 726 capable of storing high-temperature liquid (hot water) in the liquid delivery volume adjusting device 720. Thereby, the whole extraction container 9 can be uniformly heated, for example, the beverage liquid (coffee liquid) can be extracted without unevenness at a desired temperature in the subsequent permeable extraction S17, and as a result, the beverage can be improved in quality.

Moreover, according to the present embodiment, the ground beans to be extracted are accumulated in the extraction container 9 in an upright posture and immersed in liquid (hot water). This liquid flows into the extraction container 9 by S121 of injecting hot water for the first time. Then, make the extraction container 9 in an upside-down position to thicken the accumulation thickness of ground beans (refer to S16), and from the extraction container 9 in the upside-down position, deliver the beverage liquid to the cup through the injection part 10c (refer to S17). The remaining liquid (hot water) is additionally poured into the extraction container 9 being sent out in S122 of injecting hot water for the second time. The liquid which is additionally poured in is mainly used for permeation extraction, and according to such an extraction form, for example, a unique flavor of permeation extraction can be imparted to beverages. Moreover, the ratio of immersion-type extraction and permeation-type extraction can be adjusted, and the range of taste, flavor, etc. that can be expressed can sometimes be expanded. As a result, high-quality beverages can be achieved.
