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

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

<2. Fluid supply unit and switching unit> The structure 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 exemplified by numbers, unless otherwise explained, it means absolute pressure. The so-called gauge pressure is the air pressure where the atmospheric pressure is set to 0 air pressure. The so-called atmospheric pressure refers to the air pressure around the extraction container 9 or the air pressure of the beverage manufacturing device. For example, when the beverage manufacturing device is installed at an altitude of 0 m, the International Civil Aviation Organization (= "International Civil Aviation Organization" [ICAO]) The reference air pressure (1013.25hPa) at an altitude of 0m of the International Standard Atmosphere ("International Standard Atmosphere" [ISA]) established in 1976.

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

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

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

The water tank 72 is also provided with a water level sensor 72c. The water level sensor 72c detects the water level of the hot water in the water tank 72. Once the water level is detected to be lower than a predetermined water level by the water level sensor 72c, water will be supplied to the water tank 72. In this embodiment, tap water is supplied via a water purifier (not shown). A solenoid valve 72d is provided in the middle of the pipe L2 from the water purifier. Once the water level sensor 72c detects a decrease 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 opened. The solenoid valve 72d is latched and the water supply is cut off. In this way, the hot water in the water tank 72 will be 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 a coffee drink 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 the pressure regulating valve 72e and the solenoid valve 72f. The pressure regulating valve 72e reduces the air pressure supplied from the air tank 71 to a predetermined air pressure. In the case of this embodiment, the pressure is reduced to 3 atmospheres (gauge pressure, 2 atmospheres). The solenoid valve 72f switches the supply and interruption of the air pressure regulated by the pressure regulating valve 72e to the water tank 72. Except when supplying 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 atmospheres. When the tap water is supplied to the water tank 72, the air pressure in the water tank 72 is reduced by the solenoid valve 72h to a pressure lower than the water pressure of the tap water (for example, less than 2.5 air pressure), so that the water pressure of the tap water can be used. to smoothly supply tap water to the water tank 72. The solenoid valve 72h switches whether or not to release the inside of the water tank 72 to the atmosphere. When the pressure is reduced, the inside of the water tank 72 is released to the atmosphere. In addition, the solenoid valve 72h releases the inside of the water tank 72 to the atmosphere when the air pressure in the water tank 72 exceeds 3 atmospheric pressure, except when the tap water is supplied to the water tank 72, and maintains the pressure in the water tank 72 at 3 atmospheric pressure.

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

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

When the production of a coffee drink is completed, in this 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 location of the liquid delivered from the extraction container 9 to either the injection part 10 c or the waste gas tank T. The switching unit 10 includes a switching valve 10a and a motor 10b that drives the switching valve 10a. The switching valve 10a switches the flow path to the injection part 10c when the coffee beverage in the extraction container 9 is dispensed. The coffee beverage is poured into the cup C from the pouring part 10c. When discharging the waste liquid (tap water) and residue (ground beans) during washing, switch the flow path to the waste gas tank T. In this embodiment, the switching valve 10a is a three-port ball valve. During cleaning, since the residue will pass through the switching valve 10a, it is appropriate for the switching valve 10a to be a ball valve. The motor 10b rotates its rotating shaft to switch the flow path.

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

<3-1. Storage device> The storage device 4 includes a plurality of tanks 40 that accommodate roasted coffee beans. In this embodiment, three tanks 40 are provided. The can 40 includes a cylindrical main body 40a that accommodates roasted coffee beans, and a handle 40b provided on the main body 40a, and is configured to be detachable from the beverage manufacturing apparatus 1 .

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

In addition, in this embodiment, a plurality of 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 weighing 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 accommodated in the tank 40 and sends them to the downstream side.

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

The collective conveyance part 42 has a guide part 42a formed at a position corresponding to the bean input port 103. The guide portion 42a forms a passage that guides the roasted coffee beans put in from the bean input port 103 to the grinding device 5 (especially the grinder 5A). Thereby, in addition to the roasted coffee beans accommodated in the tank 40, a coffee beverage using 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 grinding device 5 includes grinders 5A and 5B and a separation device 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 then ground by the grinder 5B to form powder, and are put into the extraction container 9 from the discharge pipe 5C.

Grinders 5A and 5B grind beans with different particle sizes. The grinder 5A is a grinder for rough grinding, and the grinder 5B is a grinder for fine grinding. The grinders 5A and 5B are respectively electric grinders and include a motor as a driving source, a rotating blade driven by the motor, and the like. By changing the rotation number of the rotating blade, the size (particle size) of the ground roasted coffee beans can be changed.

The separator 6 is a mechanism that separates unnecessary materials from ground beans. The separation device 6 includes a passage portion 63a arranged between the grinder 5A and the grinder 5B. The passage portion 63a is a hollow body 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 (the left-right direction in the case of the present embodiment) intersecting the passing direction of the ground beans (the up-and-down direction in the case of the present embodiment), and the passage portion 63b is connected to the suction unit 60 . By sucking the air in the passage portion 63a with the suction unit 60, lightweight objects such as thin skin or fine powder can be sucked. In this way, unnecessary materials can be separated from the ground beans.

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

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

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

A plurality of fins (fins) 61d are integrally formed on the peripheral surface of the exhaust pipe 61b. A 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 61d, the air containing the unwanted matter D is promoted to circulate around the exhaust pipe 61b.

In this embodiment, the lower part 62 is made of a translucent material such as acrylic or glass, and the entire lower part 62 is a transparent container that is a transmissive part. Moreover, the lower part 62 is a part covered with the cover part 102 (FIG. 2). Managers or consumers of drinks can see unnecessary items D accumulated in the lower portion 62 through the cover portion 102 and the peripheral wall of the lower portion 62 . For managers, it is sometimes easy to confirm the cleaning timing of the lower part 62. For drink drinkers, by seeing that unnecessary objects D have been removed, expectations for the quality of the coffee drinks being produced may be increased. .

In this embodiment, the roasted coffee beans supplied from the storage device 4 are first coarsely ground with the grinder 5A, and when the coarsely ground beans pass through the passage portion 63a, unnecessary substances are separated by the separation device 6. Don't want things to be separated The coarsely ground beans are finely ground using grinder 5B. The unwanted materials separated in the separation device 6 are represented by thin skin or fine powder. These sometimes reduce the taste of coffee drinks, but by removing thin skins from ground beans, the quality of coffee drinks can be improved.

The grinding of roasted coffee beans can also be done with a grinder (one-stage grinding). However, like this embodiment, by using two grinders 5A and 5B for two-stage grinding, the particle size of the ground beans can be easily made uniform, and the degree of extraction of the coffee liquid can be made constant. When beans are crushed, heat is sometimes generated by friction between a cutting tool (cutter) and the beans. Through the two-stage grinding, it is also possible to suppress the heat generated by friction during grinding and prevent the deterioration of the ground beans (such as a decrease in flavor).

In addition, by passing through the stages of coarse grinding → separation of unnecessary materials → fine grinding, when unnecessary materials such as thin skins are separated, the quality difference between the unnecessary materials and the ground beans (essential parts) can be widened. This can improve the separation efficiency of unnecessary materials and prevent the ground beans (essential part) from being separated as unnecessary materials. In addition, by intervening between coarse grinding and fine grinding to separate unnecessary materials using air suction, the heat generation of ground beans can be suppressed through air cooling.

The support member 800 is fixedly installed so that its relative position to the frame F does not change, and accommodates the holding member 801 . The support member 800 further includes a communication portion 800a that communicates the pipe L3 with the inside of the support member 800 . Hot water, tap water, and air pressure supplied from the pipe L3 are introduced into the support member 800 via the communication portion 800a.

The holding member 801 is a member that detachably holds the cover unit 91 . The holding member 801 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 these. This mechanism is, for example, a snap ring mechanism, which is engaged by a certain pushing force and released by a certain separation force. Hot water, tap water, and air pressure supplied from the pipe L3 can be supplied into the extraction container 9 via the communication portion 800a and the communication hole 801a of the holding member 801.

The holding member 801 is also a movable member provided in the support member 800 so as to be slidable in the up and down direction. The lifting shaft 802 is provided so that its axis direction becomes the up-down direction. The lifting shaft 802 passes through the top of the support member 800 in the up-down direction airtightly, and is provided to be able to move up and down freely on the support member 800 .

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

A bolt 802a constituting a lead screw mechanism is formed on the outer peripheral surface of the lifting shaft 802. The bolt 802a is screwed onto the nut 804b. The upper unit 8A is equipped with a motor 804a, and the nut 804b is currently rotated (without moving up and down) by the driving force of the motor 804a. The lifting shaft 802 will rise and fall by the rotation of the nut 804b.

The lifting shaft 802 is a tubular shaft having a through hole on the central axis, and the probe 803 is inserted into the through hole so as to be slidable up and down. The probe 803 penetrates the top of the holding member 801 in an airtight manner in the vertical direction, and is provided to be able to move up and down freely relative to the support member 800 and the holding member 801 .

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

A bolt 803a constituting a lead screw mechanism is formed on the outer peripheral surface of the probe 803. The bolt 803a is screwed onto the nut 805b. The upper unit 8A is equipped with a motor 805a, and the nut 805b is rotated immediately (without moving up and down) by the driving force of the motor 805a. The probe 803 will rise and fall by the rotation of the nut 805b.

The lower unit 8C includes an operating unit 81C. The operating unit 81C is a structure in which the operating unit 81A is turned upside down, and performs opening and closing operations of the valves 913 and 903 provided inside the convex portions 911d and 901c. The operating unit 81C is also configured to open and close the cover unit 91. However, in this embodiment, the operating unit 81C is not used to open and close 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 support member 810, a holding member 811, a lifting shaft 812, and a probe 813.

The support member 810 is fixedly installed so that its relative position to the frame F does not change, and accommodates the holding member 811 . The support member 810 further includes a communication portion 810 a that communicates 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 to 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 these. This mechanism is, for example, an engagement mechanism, which engages with a certain pushing force and releases the engagement with a certain separation force. The coffee beverage, tap water, and ground bean residue in the container body 90 are introduced to the switching valve 10a via 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 lifting shaft 812 is provided so that its axial direction becomes the up-down direction. The lifting shaft 812 passes through the bottom of the support member 800 airtightly in the vertical direction, and is provided to be able to move up and down freely on the support member 810 .

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

A bolt 812a constituting a lead screw mechanism is formed on the outer peripheral surface of the lifting shaft 812. The bolt 812a is screwed onto the nut 814b. The lower unit 8C is equipped with a motor 814a, and the nut 814b is currently rotated (without moving up and down) by the driving force of the motor 814a. The lifting shaft 812 will rise and fall by the rotation of the nut 814b.

The lifting shaft 812 is a tubular shaft having a through hole on the central axis, and the probe 813 is inserted into the through hole so as to be able to slide up and down. The probe 813 penetrates the bottom of the holding member 811 in an airtight manner in the vertical direction, and is provided vertically and vertically with respect to the support member 810 and the holding member 811.

The probe 813 is an operating member that opens and closes the valves 913 and 903 provided inside the convex portions 911d and 901c. By raising the probe 813, the valves 913 and 903 can be changed from a closed state to an open state. The drop of the valve changes the valve from the open state to the closed state (by the action of the return spring (not shown)).

A bolt 813a constituting a lead screw mechanism is formed on the outer peripheral surface of the probe 813. The bolt 813a is screwed onto the nut 815b. The lower unit 8C is equipped with a motor 815a, and the nut 815b is rotated immediately (without moving up and down) by the driving force of the motor 815a. The probe 813 will rise and fall by the rotation of the nut 815b.

＜4-4. Middle unit＞ The middle unit 8B will be described with reference to FIGS. 5 and 9 . FIG. 9 is a schematic diagram of the middle unit 8B. The middle unit 8B includes a support unit 81B that supports the extraction container 9 . The support unit 81B includes a unit body 81B' that supports the locking mechanism 821 in addition to the arm member 820 described above.

The locking mechanism 821 is a mechanism that maintains the lid unit 91 in a closed state with respect to the container body 90 . The locking mechanism 821 is a pair of holding members 821a that holds the brim portion 911c of the lid unit 91 and the flange portion 90c of the container body 90 up and down. The pair of holding members 821a has a C-shaped cross section that is fitted between the brim portion 911c and the flange portion 90c, and is opened and closed in the left-right direction by the driving force of the motor 822. When the pair of holding members 821a are in the closed state, each holding member 821a is fitted into the brim 911c and the flange 90c so as to sandwich the brim 911c and the flange 90c up and down, as shown by the solid line in the circled figure in Fig. 9 etc., the cover unit 91 will be airtightly locked with respect to the container body 90 . In this locked state, even if the holding member 801 is lifted by the lifting shaft 802 to open the cover unit 91, the cover unit 91 does not move (the lock is not released). That is, the force of locking by the locking mechanism 821 is set to be stronger than the force of using the retaining member 801 to open the cover unit 91 . This can prevent the lid unit 91 from being in an open state with respect to the container body 90 during abnormal conditions.

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

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

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 driving source. Thereby, the container body 90 supported by the arm member 820 can be moved between the extraction position (state ST1) on the rear side and the bean insertion position (state ST2) on the front side. The bean input position is a position where ground beans are inserted into the container body 90. The ground beans ground in the grinder 5B are inserted from the discharge pipe 5C into the opening 90a of the container body 90 from which 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 a position in which the container body 90 can be operated by the operation unit 81A and the operation unit 81C, and is a position coaxial with the probes 803 and 813 to extract coffee liquid. The extraction position is a position further inside than the bean insertion position. Figures 5, 7 and 8 all show the container body 90 in the extracted position. By making the position of the container body 90 different when inserting ground beans, extracting coffee liquid, and supplying water, it is possible to prevent the hot air generated when the coffee liquid is extracted from adhering to the discharge pipe 5C of the supply part of the ground beans.

The middle unit 8B further includes a mechanism for rotating the support unit 81B around an axis 825 in the front-rear direction using a motor 824 as a driving source. Thereby, the posture of the container body 90 (the container 9 is drawn out) can be changed from the upright posture (state ST1) with the neck 90b on the upper side to the inverted posture (state ST3) with the neck 90b on the lower side. While the container 9 is being drawn out, the cover unit 91 is locked in the container body 90 by the locking mechanism 821 . In the upright and inverted postures, the top and bottom of the container 9 will be reversed when the container 9 is drawn out. In the inverted posture, the convex portion 911d is located at the position of the convex portion 901c in the upright posture. In addition, in the inverted posture, the convex portion 901c is located at the position of the convex portion 911d in the upright posture. Therefore, in the inverted posture, the operating unit 81A can open and close the valve 903, and the operating unit 81C can open and close the valve 913.

<5.Control device>

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

The control device 11 controls the entire beverage production device 1 . 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 a processor such as a CPU. The memory unit 11b is, for example, RAM or ROM. The I/F unit 11c is an input/output interface that performs input/output of signals between an external device and the processing unit 11a. The I/F unit 11c also 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 can communicate with a portable terminal device 17 such as a smartphone via the communication network 15 and, for example, can receive information such as reservations for beverage production or comments from the portable terminal device 17 of drink drinkers.

The processing unit 11a executes the program stored in the memory unit 11b, and controls the actuator group 14 based on instructions from the information display device 12, detection results of the sensor group 13, or instructions from the server 16. The sensor group 13 is a variety of sensors provided in the beverage making device 1 (for example, the temperature of hot water). degree sensor, mechanism action position detection sensor, pressure sensor, etc.). The actuator group 14 is various actuators (for example, a motor, a solenoid valve, a heater, etc.) provided in the beverage manufacturing apparatus 1 .

<6. Motion control example>

An example of the control processing of the beverage manufacturing device 1 executed by the processing unit 11a will be described with reference to FIGS. 11A (A) and (B). FIG. 11(A) shows a control example regarding one coffee beverage making operation. The state of the beverage manufacturing apparatus 1 before the manufacturing instruction is called a standby state. The status of each mechanism in the standby state is as follows.

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

In the standby state, if there is an instruction to make a coffee beverage, the process of FIG. 11(A) is executed. In S1, preheating is performed. In this process, hot water is injected into the container body 90 and the container body 90 is heated in advance. First, valves 903 and 913 are opened. Thereby, the pipe L3, the extraction container 9, and the exhaust gas tank T become connected.

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

In S2, a grinding process is performed. Here, the roasted coffee beans are crushed and the ground beans are put into the container body 90. First, the locking mechanism 821 is set to the open state, and the holding member 801 is raised to the raised position. The cover unit 91 is held by the holding member 801 and rises together with the holding member 801 . As a result, the lid unit 91 is separated from the container body 90 . The holding member 811 is lowered to the lowered position. Move the container body 90 to the bean input position. Next, the storage device 4 and the crushing device 5 are actuated. 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 unnecessary matter is separated by the separation device 6 . The ground beans are put into the container body 90 .

Return the container body 90 to the extracted position. The holding member 801 is lowered to the lowered position, and the lid unit 91 is attached to the container body 90 . The locking mechanism 821 is set to the closed state, so that 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 of S3.

In S11, in order to simmer the ground beans in the extraction container 9, an amount of hot water smaller than one cup of hot water is injected into the extraction container 9. Here, the solenoid valve 72i is opened for a predetermined time (for example, 500 ms) and then closed. Thereby, hot water is injected from the water tank 72 into the extraction container 9 . Then, it waits for a predetermined time (for example, 5000 ms) and ends the process of S11. This process can be used to steam and grind beans. By steaming and grinding the beans, the carbonic acid gas contained in the ground beans can be released, improving the subsequent extraction effect.

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

By the process of S12, the inside of the extraction container 9 can be brought into a state where the 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 solenoid valve 73b is opened and closed for a predetermined time (for example, 1000 ms), and the inside of the extraction container 9 is pressurized to a pressure at which hot water does not boil (for example, about 4 barometers (gauge pressure, 3 barometers)). Then, the valve 903 is closed.

Next, this state is maintained for a predetermined time (for example, 7000 ms), and the coffee liquid is extracted by immersion (S14). Thereby, the immersion type coffee liquid is extracted under high temperature and high pressure. The following effects can be expected from immersion extraction under high temperature and high pressure. First, by creating high pressure, hot water can easily penetrate into the inside of the ground beans, which can accelerate the extraction of coffee liquid. Second, by creating high temperatures, the extraction of coffee liquid is accelerated. Third, by creating high temperatures that reduce the viscosity of the oil contained in the ground beans, oil extraction is promoted. Thereby, a coffee drink with a high aroma can be produced.

The temperature of hot water (high-temperature water) only needs to exceed 100 degrees Celsius, but higher temperatures are advantageous when extracting coffee liquid. On the other hand, in order to increase the temperature of hot water, the cost generally becomes high. Therefore, the temperature of the hot water may be, for example, 105°C or higher, or 110°C or higher, or 115°C or higher, and may be, for example, 130°C or lower, or 120°C or lower. The air pressure is as long as the hot water does not boil.

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

The pressure inside the extraction container 9 is rapidly reduced to a pressure lower than the boiling point pressure, and the hot water in the extraction container 9 boils all at once. The hot water and ground beans in the extraction container 9 are exploded in the extraction container 9 . This allows hot water to boil evenly. In addition, it can accelerate the destruction of the cell walls of ground beans and further promote the subsequent extraction of coffee liquid. Moreover, this boiling can also stir the ground beans and hot water, thereby promoting the extraction of coffee liquid. In this way, in this embodiment, the extraction efficiency of coffee liquid can be improved.

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

In S17, the permeable coffee liquid is extracted and the coffee beverage is sent to the cup C. Here, the switching valve 10a is switched so that the injection part 10c It communicates with the communication part 810a of the operation unit 81C. Furthermore, both valves 903 and 913 are set to the open state. Furthermore, the solenoid valve 73b is opened for a predetermined time (for example, 10000 ms), and a predetermined air pressure (for example, 1.7 air pressure (gauge pressure, 0.7 air pressure)) is formed in the extraction container 9 . In the extraction container 9 , the coffee beverage in which the coffee liquid is dissolved in the hot water passes through the filter provided in the cover unit 91 and is sent to the cup C. The filter limits the leakage of grinding bean residues. Through the above, the extraction process is completed.

In this embodiment, the extraction efficiency of the coffee liquid can be improved by using both the immersion type extraction in S14 and the penetration type extraction in S17. When the container 9 is drawn out and in the upright position, the ground beans are accumulated from the waist 90e to the bottom 90f. On the other hand, when the container 9 is drawn out in an inverted posture, ground beans reach the neck 90b from the shoulder 90d and are accumulated. The cross-sectional area of the waist 90e is larger than the cross-sectional area of the neck 90b, and the accumulation thickness of ground beans in the inverted posture is thicker than that in the upright posture. That is, the ground beans are stacked relatively thinly and widely when the extraction container 9 is in the upright posture, and are stacked relatively thickly and narrowly in the inverted posture.

In this embodiment, since the immersion extraction in S14 is performed with the extraction container 9 in an upright position, hot water can be brought into contact with the ground beans in a wide range, thereby improving the extraction efficiency of the coffee liquid. However, in this case, there is a tendency for the hot water and the ground beans to partially come into contact. On the other hand, the penetration type extraction in S17 is performed with the extraction container 9 in an inverted posture, so the hot water passes through the accumulated ground beans while coming into contact with more ground beans. The hot water will come into contact with the ground beans more everywhere, which can further improve the extraction efficiency of coffee liquid.

Returning to FIG. 11(A) , the extraction process of S3 is followed by the discharge process of S4. Here, the cleaning process within the extraction container 9 is performed. Cleaning of the extraction container 9 is performed by returning the extraction container 9 from the inverted position to the upright position, and supplying tap water (purified 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 waste gas tank T together with the residue of the ground beans.

Through the above, one coffee beverage manufacturing process is completed. Later, the same process is repeated per manufacturing instructions. The time required to make a coffee drink is about 60 to 90 seconds, for example.

<7. Overview of device configuration> As mentioned above, the beverage manufacturing device 1 includes the bean processing device 2 and the extracting device 3 as the manufacturing part. More specifically, the bean processing device 2 includes the storage device 4 and the crushing device 5, and the extracting device 3 includes the fluid supply unit 7 and the drive unit. unit 8, extraction container 9, and switching unit 10 (see FIG. 2, FIG. 3, etc.). The grinding device 5 receives one cup of roasted coffee beans from the storage device 4, and grinds the beans in two stages using the grinders 5A and 5B. At this time, unnecessary materials such as thin skins are separated from the ground beans by the separation device 6 . After the ground beans are put into the extraction container 9, the fluid supply unit 7 injects hot water into the extraction container 9, the drive unit 8 reverses the posture of the extraction container 9, and the switching unit 10 moves the extraction container 9 from the extraction container 9 to the cup C. Dispensing of liquids, etc., to provide drinks by the glass.

A part of the above-mentioned manufacturing part is covered by the cover part 102 which is formed as a transparent cover as a whole and is visible to users (for example, the manager of the device 1, drink consumers, etc.) from outside the device 1. In the present embodiment, in the above-mentioned manufacturing part, a plurality of canisters 40 of a part of the storage device 4 are exposed, and other elements are substantially housed in the housing 100. However, the manufacturing part may also be used. All of them are housed in the casing 100 as another embodiment. In other words, the cover part 102 may cover at least a part of the manufacturing part.

At least part of the production part is covered by the cover part 102 so as to be visible from the outside of the device 1. For example, when the user is a manager of the device 1, the manager may sometimes prepare the device together with the preparation of the beverage. action check. When the user is a purchaser of a beverage, the purchaser may wait for the completion of production of the beverage while raising expectations 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 102 , and among several processes of producing a beverage, the extraction process that is of high interest to the user can be observed. The drive unit 8 functions as a posture changing unit that changes the posture of the drawn container 9. As mentioned above, the drawn container 9 is a movable part that can be reversed up and down in the manufacturing unit. Therefore, sometimes the reversing action of the extraction container 9 is more likely to arouse the user's interest, and the user can observe this, making the user enjoy it.

On the other hand, in order to further improve the quality of the beverage provided by the beverage production device 1, for example, the improvement of the process, the structural surface and the control surface of the device 1 to realize the improvement of the process, etc. Improvements were also requested. An example of this is to change some of the elements included in the device 1 . Hereinafter, an example of the liquid delivery amount adjusting device 720 that can function as the water tank 72 in FIG. 3 will be described with reference to FIGS. 12 to 14 .

＜8.Configuration example of liquid feeding amount adjustment device＞ FIG. 12 is a schematic diagram showing the liquid feed amount adjusting device 720. In addition, FIG. 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 liquid delivery amount adjusting device 720 is a tank that stores hot water (water) constituting the coffee drink, like the water tank 72, and has a function of delivering a certain amount of hot water. Thereby, the hot water necessary for one cup of coffee drink can be delivered sequentially, and the amount of hot water at this time can also be changed. In the following description, components having the same functions as those related to the water tank 72 are denoted by the same reference numerals.

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

The space 725 constitutes a storage portion for storing hot water. The space 725 is also called a storage part 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 called a storage portion 726 . By separating the storage portion 725 and the storage portion 726 with a common inter-wall partition 722, the size of the tank 720a can be reduced more than by dividing the storage portions 725 and 726 with separate walls.

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

The portion of the upper wall 723 that defines the storage portion 725 is connected to a pipe that supplies air pressure in the air tank 71 (see FIG. 3 ), and a solenoid valve 72f is provided here. The liquid supply amount adjusting device 720 is equipped with a sensor (not shown, for example, a sensor equivalent to the pressure sensor 72g in FIG. 3) that detects the air pressure in the storage part 725. The solenoid valve 72f is switched to the pressure regulating state. The valve 72e (see FIG. 3 ) is configured to supply and block the regulated air pressure to the storage portion 725 . The solenoid valve 72f is opened and closed so that the air pressure in the storage part 725 is maintained at 3 atmospheres except when water is supplied to the storage part 725.

The portion of the upper wall 723 that defines the storage portion 725 is also connected to a pipe that connects the storage portion 725 to the atmosphere. Here, a solenoid valve 72h is provided. When supplying tap water to the storage part 725, the air pressure of the storage part 725 is reduced 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 water pressure. . The solenoid valve 72h switches whether or not to release the inside of the water tank 72 to the atmosphere, and when the pressure is reduced, the inside of the storage part 725 is released to the atmosphere. In addition, the solenoid valve 72h releases the storage part 725 to the atmosphere when the air pressure in the storage part 725 exceeds 3 atmospheres except when water is supplied to the storage part 725, and maintains the storage part 725 at 3 atmospheres.

The portion of the bottom wall 724 that defines the storage portion 725 is a pipe L2 that connects the supply of tap water to the storage portion 725, and a 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 part 725.

The portion of the bottom wall 724 that defines the storage portion 725 is also connected to the pipe L2' for discharging the hot water in the storage portion 725, and a solenoid valve 72d' is provided here. The solenoid valve 72d' is opened when the hot water in the storage 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 supplies hot water from the storage part 725 via the pipe 728a, the solenoid valve 728, and the pipe 728b. The pipe 728a is connected between the portion of the bottom wall 724 that defines the storage portion 725 and the solenoid valve 728. The pipe 728b is connected between the portion of the bottom wall 724 defining the storage portion 726 and the solenoid valve 728.

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

By switching the communication and interruption between the pipe 728b and the pipe 728a, the communication and interruption between the storage part 725 and the storage part 726 can be switched. By switching the connection and interruption between the pipe 728b and the pipe 728c, it is possible to switch the delivery and storage of the hot water in the storage part 726.

When the solenoid valve 728 connects the pipe 728b and the pipe 728a, it blocks the pipe 728b and the pipe 728c. On the contrary, when the pipe 728b and the pipe 728c are connected, the pipe 728b and the pipe 728a are blocked. The arrows indicated by the solenoid valve 728 in the figure indicate the operating state of the solenoid valve 728. In the example of FIG. 12 , the arrow indicates the state in which the pipe 728b and the pipe 728c are connected and the pipe 728b and the pipe 728a are blocked.

In addition, here, by using the solenoid valve 728 as a three-way valve, the switching can be performed by one solenoid valve 728 . However, the pipe 728b may be divided into two, and a valve may be provided to switch communication and interruption between the one pipe 728b and the pipe 728a, and a valve to switch communication and interruption between the other pipe 728b and the pipe 728c.

The liquid feed amount adjusting device 720 includes a drive unit 727 . The driving unit 727 is controlled according to the amount of hot water sent from the storage part 726 to change the volume of the storage part 726. The amount of hot water required for one cup varies depending on the size of the coffee cup. The driving unit 727 adjusts the volume of the storage portion 726 so that an appropriate amount of hot water is delivered from the storage portion 726 in accordance with the size of the coffee cup.

The drive unit 727 is a mechanism that changes the volume of the storage portion 726 by moving the movable member 727c up and down. The movable member 727c is a piston-shaped member inserted into the space 726A and slid in the up-and-down direction, and its bottom surface 727d forms the upper wall of the storage portion 726. From this point of view, the movable member 727c is called a piston unit or the like, and the space 726A is also called a cylinder unit or the like. As the bottom surface 727d rises and falls, the volume of the storage portion 726 changes.

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

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

This groove 727e is formed to communicate with an 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 the hot water in the storage part 725 (the position of the sensor 731b to be described later), and is an air communication part that connects the storage part 725 to the space 726A. The air will communicate with the storage part 725 and the storage part 726 through the opening 722a and the groove 727e, and the air pressure in these spaces will become the same. In addition, when the storage parts 725 and 726 are always set to atmospheric pressure, individual passages connected to the atmosphere may be provided.

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

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

The water level sensor 72c is a measuring unit that measures 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 provided in the storage part 729, a sensor 731a for detecting the lower side of the float 730, and a sensor for the upper side. 731b.

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 via the communication part 729a. The communication part 729b is an air communication part that connects the storage part 725 and the storage part 729. The air communicates between the storage part 725 and the storage part 729 through the communication part 729b. 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 made of a permeable member such as glass or acrylic. Thereby, the water level of the hot water in the storage part 729 can be seen 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, it is also possible to adopt a structure in which a transparent part is provided in a part of the peripheral wall (721) of the storage part 725 so that the water level can be viewed.

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

The sensors 731a and 731b are, for example, light sensors (photointerrupters), and detect the float 730 from the outside of the storage part 729. Once the float 730 is detected by the sensor 731a, the solenoid valve 72d is opened and water is supplied to the storage part 725. That is, the sensor 731a monitors the lower limit of the water level of the hot water in the storage part 725. The lower limit of the water level is set at a higher position than the heater 72a, thereby preventing the heater 72a from burning dry.

When the float 730 is detected by the sensor 731b, the solenoid 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 part 725.

The same structure as the water level sensor 72c may be built inside the storage part 725. However, as in this example, by constructing the water level sensor 72c outside the storage part 725, the water level of the storage part 725 can be easily confirmed from the outside.

Next, an operation example of the liquid feed amount adjusting device 720 will be described with reference to FIG. 14 . First, the volume of the storage part 726 is adjusted by the drive unit 727 according to the size of the cup. State ST61 shows this. In the example of the same figure, the movable member 727c is lowered, and the volume of the storage part 726 is set to a smaller volume than the example of FIG. 13 . The solenoid valve 728 connects 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 part 726 is set, the drive unit 727 is stopped, and the solenoid valve 728 connects the pipe 728b and the pipe 728a. 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 this example, since the water level of the hot water in the storage part 725 is lower than the lowest level of the hot water (the position of the sensor 731a (set) at a lower position, so a head difference often occurs between the storage part 725 and the storage part 726 (the hot water in the storage part 725 is higher). Therefore, hot water is supplied from the storage part 725 to the storage part 726 until the storage part 726 is full. State ST62 indicates that the storage portion 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 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 preservation performance of the stored hot water can be ensured. In addition, the volume of the storage part 726 may be changed by the drive unit 727 in the state ST62.

The hot water supply from the storage part 725 to the storage part 726 may be supplied by other methods. However, 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 part 726 is sent out. As shown in state ST63, the solenoid valve 728 connects the pipe 728b and the pipe 728c, and hot water can be sent out from the pipe 728c to the extraction container 9 by its own weight or the air pressure of the storage part 726. After the delivery of hot water starts, the operating state of the solenoid valve 728 is also blocked between any of the pipes, so that the hot water in the storage portion 726 can be delivered in stages. For example, for the steaming process (S11 in Fig. 11(B)), the hot water supply may be interrupted, and then the remaining hot water may be sent out (S12 in Fig. 11(B)).

In short, the entire amount of hot water stored in the storage part 726 is delivered. The delivery confirmation of the full amount can be performed during the opening time of the solenoid valve 728 (the communication time between the pipe 728b and the pipe 728c). It can also be stored every time it is sent out When there is hot water in the storage part 726, the solenoid valve 72d is opened and water corresponding to this amount is supplied to the storage part 725.

According to the above example, the amount of hot water delivered can be adjusted. The amount of liquid delivered is generally controlled by using a flow sensor to open and close a valve based on its detection results. However, in the case of high-temperature liquids or special liquids, corresponding flow sensors may not be commercially available or may be expensive. On the other hand, according to the above example, by adjusting the volume of the storage portion 726, a flow sensor can be used to adjust the hot water delivery amount.

<9. Action control example when using the liquid delivery amount adjustment device>

By using the above-described liquid delivery amount adjusting device 720, for example, a part of the manufacturing process can be changed to further improve the quality of the beverage provided by the beverage manufacturing device 1. Hereinafter, an example of the control processing of the device 1 executed by the processing unit 11a (see Fig. 10 ) of the control device 11 will be described with reference to Fig. 15 . In addition, for descriptions that are omitted below, reference can be made to the aforementioned steps of FIGS. 11(A) and 11(B) and the operation contents of the liquid delivery amount adjusting device 720 in FIGS. 12 to 14 .

FIG. 15 shows a control example regarding one coffee beverage making operation. First, the preheating process S1 is divided into at least two heating processes S101 and S102 (let it be S1' in order to distinguish it from S1 in Fig. 11(A) ).

S101 is a process of injecting hot water into the extraction container 9 (container body 90) and warming the extraction container 9 in advance. First, the solenoid valve 728 is controlled to connect the pipe 728a and the pipe 728b, 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 to cause the piping to 728b communicates with the pipe 728c, and sends the hot water in the storage part 726 to the extraction container 9 via the pipe L3. Next, the solenoid valve 73 is controlled to pressurize the inside of the extraction container 9 and the hot water in the extraction container 9 is discharged to the waste tank T.

The inside of the extraction container 9 and the pipes L2 to L3 are preheated in S101, which prevents the hot water from getting cold between the production of beverages in each process described later. In addition, by performing S101, residues (liquid residues, etc.) in the flow path generated during previous or past extractions may be flushed away.

S102 is a process of supplying the steam generated in the storage parts 725 and 726 into the container body 90 and extracting the container 9 and heating it. This steam can be generated by decompressing the storage portions 725 and 726 to boil the hot water in the storage portions 725 and 726, and can be realized by the same procedure as S15 (see 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 pipe 728b and the pipe 728c.

By performing S102, the entire extraction container 9 can be heated uniformly. Thereby, for example, liquid can be extracted from ground beans without unevenness at a desired temperature, and as a result, the quality of the beverage can be improved. Furthermore, in S102, the air pressure of the storage portions 725 and 726 decreases and the liquid therein begins to boil. Therefore, the liquid can be stirred to uniformize the temperature.

Incidentally, in S102, the pipe L3, which functions as a connecting portion that connects the storage portions 725 and 726 to the extraction container 9 and forms a flow path therebetween, is heated together with the extraction container 9. Thereby, when the liquid passes through the pipe L3, the liquid will not become cold.

Here, as mentioned above, the extraction container 9 has valves 903 and 913, which serve as inlets or outlets for hot water and steam. The hot water is used for the above-mentioned extracted liquid, and the steam is used. The beverage liquid (coffee liquid in this example) obtained by the above extraction or heating in S102. In this example, in S102, the steam flows into the extraction container 9 from the valve 913, and flows out of the extraction container 9 from the valve 903. When the vapor flows from the valve 913 into the extraction container 9, the valve 903 is open. Therefore, when the vapor is liquefied in the extraction container 9 to form a liquid, the liquid will not remain in the extraction container 9 for a long time. It can flow out from the valve 903 to the outside of the extraction container 9 . According to this aspect, for example, when a beverage is produced through each process described below, the taste, flavor, etc. of the beverage will not be unintentionally thinned, so it is beneficial to improve the quality of the beverage.

Alternatively, after filling the extraction container 9 with steam, both the valves 903 and 913 may be closed and the extraction container 9 may be vibrated. The vibration of the extraction container 9 can be achieved by the motors 823 and/or 824 of the middle unit 8B (see FIG. 9 ). By applying vibration to the extraction container 9 whose interior is filled with steam, the steam expands uniformly within the extraction container 9 and the entire extraction container 9 can be heated uniformly.

In addition, instead of/in addition to the above-mentioned S102, 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 executed twice in total before and after S101. By performing S102 before S101, it may be easier to remove the residue generated during the previous extraction in S101.

After performing the preheating process S1' as above, S2 is performed in the same procedure as in Fig. 11(A), and then the extraction process is performed (referred to as S3' in order to distinguish it from S3 in Fig. 11(A)). In the extraction process S3', the hot water injection process S12 for actual extraction is divided into at least two hot water injection processes S121 and S122. The first injection of hot water S121 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 accumulated in the extraction container 9 in the upright posture with a relatively thin accumulation thickness, and the ground beans are immersed in the hot water supplied in S121. After the hot water in the extraction container 9 is boiled in S15 and the extraction container 9 is reversed to form an inverted posture in S16, S122 of injecting hot water for the second time is performed after or together with S17.

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

As mentioned above, when the container 9 is drawn out in an upright posture, the ground beans are accumulated from the waist 90e to the bottom 90f. On the other hand, when the container 9 is drawn out in an inverted posture, the ground beans are accumulated from the shoulder 90d to the neck 90b. pile up. That is, the extraction container 9 includes a thick portion from the waist 90e to the bottom 90f and a thin portion from the shoulder 90d to the neck 90b. Ground beans are accumulated in the thick portion in the upright posture and in the inverted posture. It is accumulated in this fine part.

During the above-mentioned through-type extraction in S17, since the extraction container 9 is in an inverted posture, the hot water in the extraction container 9 passes through the ground beans that are thicker and accumulated than in the upright posture, and comes into contact with the ground beans everywhere. Therefore, high efficiency of permeable extraction can be achieved. Here, S122 for injecting hot water for the second time is performed together with S17. Therefore, the extraction container 9 additionally receives the beverage liquid obtained by immersion extraction of the hot water received in S121 while sending it out in S122. Hot water. Furthermore, the hot water additionally flowing into the extraction container 9 in S122 is essentially not used in the immersion type extraction, but is mainly used in the penetration type extraction. According to such an extraction form, the unique flavor of permeation extraction can be effectively imparted to the beverage, and the quality of the beverage can be improved.

The amount of hot water injected in S121 and the amount of hot water injected in S122 can also be set or even changed by the user, for example, that is, the ratio of immersion extraction and permeation extraction can be adjusted. Thereby, it is sometimes possible to produce a drink with a quality corresponding to the user's preference.

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

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

16(b) to 16(c) show the form of the liquid feed amount adjusting device 720 corresponding to the above-mentioned S101 (heating process of extracting 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 closing the valve 7281, in the process of FIG. 16(c), the valve 7282 is opened, and as shown by the dotted arrow, the hot water in the storage part 726 is supplied to the extraction container 9. Thereby, the inside of the extraction container 9 and the pipes L2 to L3 are heated.

16(d) to 16(e) show the form of the liquid feed amount adjusting device 720 corresponding to the above-mentioned S102 (heating process of the steam extraction container 9). In the process of FIG. 16(d) , the pressure in the storage parts 725 and 726 is reduced to boil the hot water in the storage parts 725 and 726, thereby generating steam in the storage parts 725 and 726. Since the valve 7282 is in the open state, the generated steam is supplied to the extraction container 9 via the pipe 728c as shown by the dotted arrow. Moreover, in the process of Figure 16(d), the hot water in the storage parts 725 and 726 can also be stirred by the above boiling, when the temperature of the stirred hot water does not reach a predetermined value (for example, 118 degrees Celsius) , the heater 72a (see FIG. 12) is driven. Then, in the process of FIG. 16(e) , the valve 7282 is closed, and the supply of steam to the extraction container 9 is stopped. Thereby, the entire extraction container 9 is heated uniformly.

16(f) to 16(h) show the form of the liquid feed amount adjusting device 720 corresponding to the preparation process for executing the extraction process S3'. In the process of Fig. 16(f), after the pressure in the storage parts 725 and 726 is returned to 3 atmospheres, in the process of Fig. 16(g), the valve 7281 is opened, as shown by the dotted arrow, and a cup of Hot water (for example, about 180 cc) moves from the storage part 725 to the storage part 726 . After the movement 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 may be preset or even selected by the user, or may be determined according to the size of the cup placed on the placement part 110 , or may be a fixed value. Although not shown here, the grinding process S2 can be carried out in parallel between the processes of FIGS. 16(f) to 16(h) , thereby shortening the time until the beverage is produced.

17(i) to 17(j) show the form of the liquid delivery amount adjusting device 720 corresponding to the injected hot water S11 for steaming. The valve 7282 is opened in the process of FIG. 17(i) and after the predetermined time has elapsed, the valve 7282 is closed in the process of FIG. 17(j). Thereby, a part of the hot water stored in the storage part 726 (for example, about 30 cc) 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 of hot water for extraction S121. After the steaming of ground beans is completed, the valve 7282 is opened in the process of Figure 17(k), and after a predetermined time has elapsed, the valve 7282 is closed in the process of Figure 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 the dotted arrow.

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

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

Then, S17 is completed by sending all the substantial portion of the beverage from the extraction container 9 to the cup. Here, after S122 and before S17 is completed, the steam in the storage parts 725 and 726 and the air pressure from the compressor 70 can be used to facilitate the delivery of the beverage. The steam in the storage parts 725 and 726 can be generated by the same procedure as S102 (the process in Figures 16(d) to 16(e)). That is, in the process of FIG. 17(n) , the pressure in the storage parts 725 and 726 is reduced and hot water is boiled, whereby steam is generated in the storage parts 725 and 726, and the steam is supplied to the extraction container through the pipe 728c. 9. At this time, similar to the process in Figure 16(d), the hot water in the storage parts 725 and 726 will be appropriately stirred, and the heater 72a will be driven as needed. Then, in the process of FIG. 17(о), the valve 7282 is closed to stop the supply of the steam. In addition, when dispensing of the beverage is promoted, the inside of the extraction container 9 is adjusted to a pressure of about 1.6 to 2 air pressure, for example.

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

Periods T1 to T2 are periods corresponding to the injected hot water for steaming S11. During the period T1, the inside of the extraction container 9 is pressurized to approximately 1.8 atmospheric pressure, and hot water (about 30 cc) for steaming is flowed into the extraction container 9 . The timing of the inflow of hot water into the extraction container 9 may be any time period T1, but may be preset or even selected by the user, or may be changed according to the type of beverage. This hot water is then used to steam the ground beans. Let this period (about 15 seconds) be a period T2.

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

Here, the amount of hot water injected can be adjusted between the periods T3 and T4. For example, the injected hot water of about 70cc can be completed in the period T3. Periods T3 and T4 have a common point of injecting hot water while pressurizing the inside of the extraction container 9, but in this example, the pressurization modes are different from each other. For example, between the pressurization period T3 and T4, the pressurization pattern will become relaxed in the middle (before and after P=3 air pressure). For example, the timing between periods T3 and T4 can also be defined as the change point of the air pressure P. By controlling or even adjusting the pressurization state during periods T3 to T4, the range of taste, flavor, etc. that can be expressed for the beverage liquid obtained by immersion extraction S14 in the subsequent process may be expanded.

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

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

As mentioned above, the liquid in the extracted container 9 will be boiled and stirred by decompression S15. According to the decompression mode of this example, first, a part of the liquid in the container 9 is drawn out and is boiled and stirred by the first stage of pressure reduction in period T6, and then the other part of the liquid in the container 9 is drawn out. It can also be boiled and stirred by the second stage of pressure reduction during period T7. Therefore, for example, the entire liquid in the extracted container 9 can be appropriately stirred, which may be advantageous when, for example, the extracted beverage liquid has uneven concentration, composition, or the like. Then, during period T8, while the pressure in the extraction container 9 is returned to 1.5 atmospheres to stabilize boiling, 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 waiting period (about 2 seconds) after the reversal S16 of extracting the container 9 . In addition, the timing of starting the period T9 corresponds to the timing when the above-mentioned reversal S16 is executed. During the period T9, in the extraction container 9 reversed in S16, the ground beans to be extracted are accumulated with a relatively thick accumulation thickness in the lower part of the extraction container 9. Then, during the period T9, the pressure inside the extraction container 9 is reduced to 1 atmosphere.

The period T10 to T11 is a period corresponding to the through-type 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, and the hot water (about 80 cc) that additionally flows into the extraction container 9 is mainly used for the penetration type extraction.

In this example, after for example S122 of 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 dispensing of the beverage. During the period T10, the steam in the storage portions 725 and 726 is used to promote the dispensing of the beverage. During the period T11, the air pressure from the compressor 70 is used to promote the dispensing of the beverage. Thereby, all 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 (how the amount of hot water changes) that changes with the passage of time as a dotted line in FIG. 18 . In this example, a total of approximately 185cc of the drink will be served.

Each of the above-mentioned periods T1 and so on, in more detail, corresponds to each step of S11 and so on or its sub-steps and is summarized as follows. that is, Period T1: hot water injection project for steaming, Period T2: steaming work, Period T3: The first hot water injection project, Period T4: Pressurization work, Period T5: high pressure impregnation project, Period T6: Rapid decompression process after high-pressure impregnation, or atmospheric release process (first half) to release the contents of the extraction container 9 to the atmosphere, Period T7: Rapid decompression 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 reversal process), and standby process waiting for the completion of stacking of the extraction objects in the container 9, Period T10: The second hot water injection process, beverage delivery process (first half), or beverage delivery promotion project using steam, Period T11: Beverage delivery process (second half), or beverage delivery promotion process using air pressure.

In addition, here, the periods T1 to T11 are schematically illustrated as having equal lengths to each other, but the actual information display device 12 displays them at long intervals corresponding to the actual time (other details will be described later). The same applies to the picture).

In the above-mentioned FIG. 19 , target values (or set values) of the air pressure and the amount of hot water in the extraction container 9 that change with the passage of time are added. How these actual values change can also be additively plotted in Information display device 12 (see FIG. 1 etc.). Thereby, when the user is a purchaser of a drink, etc., the user may not be bored by waiting. In addition, when the user is a manager of the device 1 or the like, the user may be able to confirm whether the production of beverages by the device 1 is appropriately executed.

FIG. 20 shows how the actual values of the air pressure and the amount of hot water in the extraction container 9 are plotted (in real time) overlaid on the target value together with the passage of time, so that the actual values can be displayed on the information display device 12 during the production of beverages. information. That is, FIG. 20 is a waveform added to FIG. 19 showing how the actual values of the air pressure and the amount of hot water in the extraction container 9 change. These actual values can be measured by pressure sensors and temperature sensors respectively as actual measured values. In the figure, the solid line shows the variation pattern of the target value of the air pressure in the extraction container 9 when one cup of beverage is extracted, and the one-dot line shows the variation pattern 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-point chain line shows the change form of the actual measured value of the amount of hot water in the extraction container 9 .

The example in FIG. 20 shows that the current process is in the middle of the period T6 (S15), and the actual measured values of the air pressure and the amount of hot water in the extraction container 9 are 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 time point is 1.2 atmospheric pressure, and the actual measured value of the amount of hot water is 100 cc. In addition, in subsequent projects, the above-mentioned measured values will continue to be drawn. According to such a display form, when the actual measured value does not reach the target value or when the actual measured value deviates significantly from the target value, the user can detect the occurrence of leakage in the flow path and the status of each element (piping, valve, etc.) forming the flow path. Defects, etc. can be responded to quickly.

FIG. 20 illustrates a state 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 measured values are displayed on the information display device 12, but a part of them may be displayed on the information display device 12. Display device 12. For example, the change pattern may be displayed only for the target value and the actual measured value of the air pressure, or the change pattern may be displayed only for the target value and the actual measured value of the amount of hot water. Alternatively, the calculation results of the target value and the actual measured value (for example, how the deviation amount changes) may be displayed.

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

Furthermore, when a cup of beverage is drawn out, changes in the above-mentioned target values and actual measured values of the air pressure and the amount of hot water in the drawn container 9 are displayed on the information display device 12 throughout the entire period T1 to T11, indicating that these changes The information can be stored in the memory unit 11b, for example. Therefore, the user can also perform predetermined operations through the information display device 12 to display the information again as needed. Thereby, the user can also confirm changes in the target value and the actual measured value during beverage production in the past, for example.

FIG. 21 shows a series of changes in the actual measured values of the air pressure and the amount of hot water in the extraction container 9 after the above-mentioned extraction (after the beverage production is completed), that is, after the period T11 (after S17 and S122). All situations are drawn. After the information representing the rendering result is stored in the memory unit 11b, it can be read out from the memory unit 11b at any time through the user's predetermined operation input, that is, the user can reproduce the above-mentioned rendering result as needed. displayed on the information display device 12 . The details will be described later. For example, when the user makes a drink again at another opportunity, the user can refer to the above drawing result as the past drink making history, which can be used as a drink making recipe.

The above-described plotting results are displayed here in a line graph format (line/curve graph format or broad timing graph format) with the horizontal axis as the time axis. Since the drawing result is displayed on the information display device 12 of the touch panel display, the user can adjust the air pressure and the amount of hot water in the pumped container 9 by performing predetermined operation inputs on the information display device 12 . The above target value is changed to the desired value. As an operation input to the information display device 12, a touch operation can be used. Typical examples thereof include a tap operation, a flick operation, a swipe operation, and a pinch in operation ( Zoom (pinch) operation), two-finger pull-out (pinch out) operation ((stretch) operation), slide (slide) operation, etc. In addition, the concept of click operation also includes double tap operation, long tap operation, etc.

FIG. 22 shows an example of the target value of the air pressure in the extraction container 9 during the change period T2 (the steaming process S11). After the information display device 12 displays the same line graph as in FIG. 21 , in response to the operation input for starting the change of the target value being performed, a touch operation can be input to the line graph of the target value. At this time, the line graph of the actual measured values may be non-displayed, or the display form may be changed (for example, the displayed color, density, etc.). Then, for example, the user can change the target value to a lower value ( For example, 1.5 barometric pressure). In the figure, a thin gray solid line represents a line graph showing the target value before the change of the air pressure in the extraction container 9 .

In addition, when an upward sliding operation is input from point P1, the target value is changed to a higher value. Furthermore, the target value is changed according to the operation amount. For example, when the operation amount is expanded, the target value is greatly changed.

In this way, after the user displays the drawing result of the past beverage production history as a line graph on the information display device 12, the user can perform a predetermined operation input on the displayed line graph. Thereby, the user can change the target value to a desired value, and use the changed target value as a beverage manufacturing recipe when the beverage is re-produced at another opportunity. That is, the user can refer to the past beverage production history to change the manufacturing process including the extraction process into a desired form, and can re-produce the beverage according to the quality of the preference. The information indicating the changed target value (or line graph) can be stored in the memory unit 11b, and the line graph indicating the changed target value can be displayed again on the information display by a subsequent user's predetermined operation. Device 12.

FIG. 22 exemplifies a form in which the target value of the air pressure in the extraction container 9 is changed, but the object of change is not limited to this.

FIG. 23 shows another example of changing the length of period T2. By the same procedure as the example in FIG. 22 , after the touch operation can be input to the line graph of the target value, the user can input a leftward sliding operation using point P2 as a starting point on the line graph, for example. Point P2 is the state corresponding to the period T2-T3 in Figure 22 . In response to the input of the above sliding operation, the length of period T2 is changed from 15 seconds to 10 seconds, for example. In addition, in the figure, point P2 is set as the line of the above-mentioned line graph. However, point P2 only needs to be the boundary between the period T2-T3 in FIG. 22 and may not be on the line of the above-mentioned line graph.

In the figure, a thin gray solid line represents a line graph indicating the target value before the change of the air pressure in the extraction container 9, and a thin gray dotted line represents a line graph indicating the target value before the change of the amount of hot water. . In this embodiment, by shortening the period T2 and lengthening the period T3, the form of the first injection of hot water S121 is changed. For example, in S121, the increase in the air pressure per unit time in the extraction container 9 becomes smaller and the amount of hot water injected into the extraction container 9 per unit time becomes smaller, that is, the hot water is relatively gently pressurized and injected.

As another embodiment, only the period T2 may be changed, and the period T3 and thereafter may be maintained (not changed). In this case, in order to distinguish the change method, you only need to enter another touch operation.

As illustrated in FIG. 24 , the change object may be a target value of the amount of hot water extracted from the container 9 . By the same procedure as the example in FIG. 22 , after reaching a state in which a touch operation can be input to the line graph of the target value, the user can, for example, input a downward sliding operation using point P3 as a starting point on the line graph. Point P3 is a target value indicating the amount of hot water during the period T5 to T6. In response to the input of the above sliding operation, the target value is changed from 100cc to 90cc, for example. In the figure, a line graph regarding the target value before the change of the amount of hot water in the extraction container 9 is represented by a thin gray dotted line.

In this way, the user can refer to the past beverage manufacturing history to change the manufacturing process into a desired form for each process and each item, and can apply various changes in the same procedure. For example, in addition to changing the above target value of the periods T1 to T11 and/or the length of each period T1 to T11, the user can also change other parameters, and can change the target value of the hot water temperature in the extraction container 9. As an example.

FIG. 25 shows the target value of the hot water temperature in the extraction container 9 during the period T1 to T11 as the other parameters displayed on the information display device 12 . In order to optimize the taste, flavor, etc. of the beverage, the user can change the target value of the hot water temperature to a desired value. In the beverage making apparatus 1, the hot water in the water tank 72 can be cooled by supplying cold water into the water tank 72, or the hot water in the water tank 72 can be heated by driving the heater 72a. Then, by causing the cooled or heated hot water to flow into the extraction container 9 , the actual measured value of the hot water temperature in the extraction container 9 can be brought close to the target value.

The actual measured value of the hot water temperature can be measured by installing a temperature sensor in the extraction container 9 . The actual measured value of the hot water temperature measured in this way is plotted with the passage of time overlaid on the target value of the hot water temperature between beverage productions, as in FIG. 20 . The information indicating the plot result of the hot water temperature is the same as the plot result regarding the air pressure and the amount of hot water in the extraction container 9. It is stored in the memory unit 11b and can be retrieved from the memory unit 11b by a predetermined operation by the user. read out.

In the above examples of FIGS. 19 to 25 , the drawing results are displayed on the information display device 12 in the form of a line chart with the horizontal axis as the time axis, but it can also be displayed in other forms. As an example of another display format, flat data (also called a list, a table, etc.) displayed in a matrix format can be cited. For example, after the line chart representing the above-mentioned drawing results is displayed on the information display device 12, in response to an operation input for changing the display format, the corresponding plane data will be displayed on the information display device 12. The display mode can be switched at any time, for example, before the start of beverage production (before period T1), or between beverage production (between periods T1 to T11), or during It is performed after the beverage production is completed (after period T11).

FIG. 26 shows the plane data D11 before the start of beverage production (before the period T1), that is, the plane data D11 corresponding to FIG. 19 in which the actual measured values are not displayed. FIG. 27 shows the plane data D12 between the beverage production period (between the periods T1 to T11), that is, the plane data D12 of FIG. 20 that is displayed during the process corresponding to the actual measured values. FIG. 28 shows the plane data D13 after the beverage production is completed (after the period T11 ), that is, the plane data D13 of FIG. 21 that corresponds to the actual measured values.

For example, as shown in the plane data D11 of FIG. 26 , the name of each process corresponding to the periods T1 to T11, its time (the length of the period), and the target values of the air pressure and the amount of hot water in the extraction container 9 and The actual measured values are displayed individually. In the plane data D11, since it is before the start of beverage production (before the period T1), the actual measured values related to the air pressure in the extraction container 9 and the amount of hot water are both displayed as "not". Then, between the beverage production (between the period T1 to T11), as shown in the plane data D12 of FIG. 27, the actual measured values of the air pressure and the amount of hot water in the extraction container 9 are based on the progress of the beverage production. displayed sequentially. After the beverage production is completed (after the period T11), as shown in the plane data D13 in Fig. 28, the actual measured values are displayed for all the periods T1 to T11.

This is omitted for simplicity of explanation, but the target value and actual measured value of the hot water temperature described with reference to FIG. 25 may also be displayed together as plane data D11 to D13.

The changes of the target values and the like described with reference to FIGS. 22 to 25 are also possible in the above-mentioned matrix display format. For example, in a state where the information display device 12 displays the flat data D11 (see FIG. 26 ), the user can make desired changes to the items that he wishes to change through a predetermined touch operation. For example, when the user performs the same change as in FIG. 22 in the matrix form display form, the time "15 seconds" corresponding to the period T2 of the plane data D11 can be changed by performing a click operation, a sliding operation, etc. becomes "10 seconds". That is, regardless of the display mode of the information display device 12, the user can change the target value and the like.

The user can also return the above-mentioned changed plane data D11 to the display in the line chart form, and can also visually confirm whether the above-mentioned change in the target value is appropriately reflected. The information indicating the changed target value (or line graph or plane data) is stored in the memory unit 11b as a recipe for beverage production, or can be read from the memory unit 11b at any time by a predetermined operation by the user. out. In addition, the memory unit 11b can store a plurality of beverage manufacturing recipes, and a data name corresponding to a flavor or the like can be added to each recipe.

As mentioned above, according to this embodiment, in a state where the ground beans and liquid hot water to be extracted are contained in the extraction container 9, the inside of the extraction container 9 is pressurized in S13 (period T4) and immersion extraction is performed. In S15 (period T6, etc.), the pressure is reduced and the beverage liquid and liquid are stirred. Then, in S17 (period T10, etc.), the inside of the container 9 is pressurized and extracted, and the beverage obtained by stirring is sent to the cup C. The user can set or even change the target value so that the air pressure in the extraction container 9 of each process becomes a desired pressure, thereby making the extraction form and the accompanying taste and flavor of the beverage corresponding to the user's preferences. Or, it can achieve high-quality beverages.

Figures 29 to 32 respectively show planar data D21 to D24 as several examples of other beverage manufacturing recipes. Plane data D21 in FIG. 29 is different from the above-mentioned planar data D11 in that it mainly compares the air pressure in the extraction container 9 at the time of lowering the through-type extraction S17 and the second injection of hot water S122 (period T10 to T11). Planar data D22 in FIG. 30 is different from the above-mentioned plane data D11 mainly in that the steaming step S11 (period T1 to T2) is omitted and the first injection of hot water S121 (period T3) is performed comparatively longer. The plane data D23 in FIG. 31 is different from the above-mentioned plane data D11 in that it mainly compares the air pressure when the pressure inside the extraction container 9 after the immersion extraction S14 is increased (period T6). The planar data D24 in FIG. 32 is different from the above-mentioned planar data D11 mainly in the point of comparatively lowering the air pressure in the extraction container 9 during the immersion extraction S14. The user can select one of the flat data D21 ~ D24, or can partially combine it with the flat data D11 to adjust the flavor, so that the flavor (bitterness, sourness, etc.) that can be applied to the beverage can be adapted to the user's preference.

These contents can be combined with each other without departing from the scope of the present invention, and can also be partially modified according to the purpose and the like. Furthermore, each term described in this specification is not used to describe the present invention.

However, for example, water may be replaced with hot water, hot water may be replaced with water, etc., and any of the descriptions may be replaced. If replaced with other records, it can also be replaced with all liquids, water vapor, high temperature water, cooling water, cold water, etc. For example, if it is described that the extraction object (for example, grinding beans for roasting coffee beans) and hot water are put into the extraction container 9, it can also be replaced by putting the extraction object (for example, grinding beans for roasting coffee beans) and cold water (just water can also be used). ) is put into the extraction container 9. If this is the case, it can also be treated as a extraction method for ice-drip coffee or the like or a beverage manufacturing device.
