<1. Outline of beverage manufacturing equipment>
FIG. 1 is a schematic diagram of the beverage manufacturing apparatus 1, and FIG. 2 is a block diagram of a control device 11 of the beverage manufacturing apparatus 1. The beverage production apparatus 1 is an apparatus for automatically producing a coffee beverage from roasted coffee beans and a liquid (here, water), and can produce one cup of coffee beverage per one production operation. The beverage production device 1 includes a bean processing device 2, an extraction device 3, and a control device 11.

  The control device 11 controls the entire beverage manufacturing device 1. The control device 11 includes a processing unit 11a, a storage unit 11b, and an I/F (interface) unit 11c. The processing unit 11a is a processor such as a CPU. The storage unit 11b is, for example, a RAM or a ROM. The I/F unit 11c inputs and outputs signals between the external device and the processing unit 11a.

  The processing unit 11a executes the program stored in the storage unit 11b, and controls the actuator group 14 based on the instruction from the operation unit 12 or the detection result of the sensor group 13. The operation unit 12 is a unit that receives a user's instruction input, and is, for example, a touch panel or a mechanical switch. The user can instruct the production of coffee beverages via the operation unit 12. The sensor group 13 is various sensors (for example, hot water temperature sensor, mechanism operating position detection sensor, pressure sensor, etc.) provided in the beverage manufacturing apparatus 1. The actuator group 14 is various actuators (for example, a motor, a solenoid valve, a heater, etc.) provided in the beverage manufacturing apparatus 1.

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

<2. Fluid supply unit and switching unit>
The configurations of the fluid supply unit 7 and the switching unit 10 will be described with reference to FIG. First, the fluid supply unit 7 will be described. The fluid supply unit 7 supplies hot water to the extraction container 9 and controls the atmospheric pressure in the extraction container 9. In this specification, when the atmospheric pressure is illustrated by a numeral, it means an absolute pressure unless otherwise specified, and the gauge pressure is an atmospheric pressure at which the atmospheric pressure is 0 atmospheric pressure. The atmospheric pressure refers to the atmospheric pressure around the extraction container 9 or the atmospheric pressure of the beverage manufacturing apparatus. For example, when the beverage manufacturing apparatus is installed at a position at an altitude of 0 m above sea level, the international civil aviation organization (= “International Civil Aviation Organization”) Aviation Organization" [[omitted] ICAO]) is the standard atmospheric pressure (1013.25 hPa) at 0 m above sea level of the International Standard Atmosphere [[omitted] 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 pressure source. The compressor 70 compresses the atmosphere and sends it out. The compressor 70 is driven using, for example, a motor (not shown) as a drive source. The compressed air sent from the compressor 70 is supplied to the reserve tank (accumulator) 71 via the check valve 71a. The pressure inside the reserve tank 71 is monitored by the pressure sensor 71b, and the compressor 70 is driven so as to be maintained at a predetermined pressure (7 atm (6 atm in gauge pressure) in this embodiment). The reserve tank 71 is provided with a drain 71c for drainage, and water generated by compression of air can be drained.

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

  The water tank 72 is also provided with a water level sensor 72c. The water level sensor 72c detects the water level of the hot water in the water tank 72. When the water level sensor 72c detects that the water level has dropped below a predetermined water level, water is supplied to the water tank 72. In the case of this embodiment, tap water is supplied via a water purifier (not shown). An electromagnetic valve 72d is provided in the middle of the pipe L2 from the water purifier, and when the water level sensor 72c detects a decrease in the water level, the electromagnetic valve 72d is opened and water is supplied. The valve 72d is closed to cut off the water supply. In this way, the hot water in the water tank 72 is maintained at a constant water level. Water may be supplied to the water tank 72 each time hot water used for manufacturing a coffee beverage is discharged.

  The water tank 72 is also provided with a pressure sensor 72g. The pressure sensor 72g detects the atmospheric pressure in the water tank 72. The water tank 72 is supplied with the atmospheric pressure in the reserve tank 71 via a pressure regulating valve 72e and a solenoid valve 72f. The pressure regulating valve 72e reduces the atmospheric pressure supplied from the reserve tank 71 to a predetermined atmospheric pressure. In the case of this embodiment, the pressure is reduced to 3 atm (2 atm in gauge pressure). The electromagnetic valve 72f switches between supply and cutoff of the atmospheric pressure adjusted by the pressure adjusting valve 72e to the water tank 72. The electromagnetic valve 72f is controlled to open and close so that the atmospheric pressure in the water tank 72 is maintained at 3 atm except when tap water is supplied to the water tank 72. When tap water is supplied to the water tank 72, the pressure in the water tank 72 is set lower than the tap water pressure by the solenoid valve 72h so that the tap water is smoothly replenished to the water tank 72. The pressure is reduced to (for example, less than 2.5 atm). The solenoid valve 72h switches whether to open the inside of the water tank 72 to the atmosphere, and opens the inside of the water tank 72 to the atmosphere when the pressure is reduced. Further, the solenoid valve 72h releases the inside of the water tank 72 to the atmosphere when the atmospheric pressure in the water tank 72 exceeds 3 atm except when the tap water is supplied to the water tank 72, and the inside of the water tank 72 becomes 3 atm. maintain.

  The hot water in the water tank 72 is supplied to the extraction container 9 via the check valve 72j, the electromagnetic valve 72i and the pipe L3. The hot water is supplied to the extraction container 9 by opening the electromagnetic valve 72i, and the hot water supply is shut off by closing the electromagnetic container 72i. The amount of hot water supplied to the extraction container 9 can be controlled by the opening time of the solenoid valve 72i. However, the opening/closing of the solenoid valve 72i may be controlled by measuring the supply amount. The pipe L3 is provided with a temperature sensor 73e for measuring the temperature of the hot water, and the temperature of the hot water supplied to the extraction container 9 is monitored.

  The atmospheric pressure of the reserve tank 71 is also supplied to the extraction container 9 via the pressure regulating valve 73a and the electromagnetic valve 73b. The pressure regulating valve 73a reduces the atmospheric pressure supplied from the reserve tank 71 to a predetermined atmospheric pressure. In the case of the present embodiment, the pressure is reduced to 5 atm (4 atm in gauge pressure). The electromagnetic valve 73b switches between supply and cutoff of the atmospheric pressure adjusted by the pressure adjusting valve 73a to the extraction container 9. The pressure inside the extraction container 9 is detected by the pressure sensor 73d. At the time of pressurizing the inside of the extraction container 9, the electromagnetic valve 73b is opened based on the detection result of the pressure sensor 73d, so that the inside of the extraction container 9 has a predetermined atmospheric pressure (in the present embodiment, a maximum of 5 atmospheric pressure (a gauge pressure of 4 atmospheric pressure). )) Pressurize. The air pressure in the extraction container 9 can be reduced by the solenoid valve 73c. The electromagnetic valve 73c switches whether to open the inside of the extraction container 9 to the atmosphere, and opens the inside of the extraction container 9 to the atmosphere when the pressure is abnormal (for example, when the inside of the extraction container 9 exceeds 5 atmospheric pressure).

  After the production of one coffee beverage is completed, in the present embodiment, the inside of the extraction container 9 is washed with tap water. The solenoid valve 73f is opened during cleaning and supplies tap water to the extraction container 9.

  Next, the switching unit 10 will be described. The switching unit 10 is a unit that switches the delivery destination of the liquid delivered from the extraction container 9 to either the pouring portion 10c or the waste 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 pouring portion 10c when the coffee beverage in the extraction container 9 is delivered. The coffee beverage is poured from the pouring portion 10c into the cup C. When discharging the waste liquid (tap water) and the residue (ground beans) at the time of cleaning, the flow path is switched to the waste tank T. The switching valve 10a is a 3-port ball valve in this embodiment. Since the residue passes through the switching valve 10a during cleaning, a ball valve is suitable for the switching valve 10a, and the motor 10b switches its flow path by rotating its rotation shaft.

<3. Bean processing equipment>
The bean processing apparatus 2 will be described with reference to FIG. FIG. 3 is a perspective view of the bean processing apparatus 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 canisters 40 in which roasted coffee beans are stored. In the case of this embodiment, three canisters 40 are provided. When distinguishing the three canisters 40, they are referred to as canisters 40A, 40B, and 40C. Each of the canisters 40A to 40C may store different types of roasted coffee beans, and the type of roasted coffee beans used for producing a coffee beverage may be selected by an operation input to the operation unit 12. Roasted coffee beans of different types are, for example, roasted coffee beans of different types of coffee beans. The roasted coffee beans of different types are coffee beans of the same type, but may be roasted coffee beans of different roasting degrees. The roasted coffee beans of different types may be roasted coffee beans of different types or roasting degrees. Further, at least one of the three canisters 40 may contain roasted coffee beans in which roasted coffee beans of a plurality of types are mixed. In this case, the roasted coffee beans of each variety may have the same degree of roasting.

  Although the plurality of canisters 40 are provided in the present embodiment, the configuration may be such that only one canister 40 is provided. When a plurality of canisters 40 are provided, the same type of roasted coffee beans may be stored in all or a plurality of canisters 40.

  Each canister 40 is provided with a conveyor 41 individually. The conveyor 41 is a delivery mechanism (transportation mechanism) that automatically delivers a predetermined amount of roasted coffee beans contained in the canister 40 to the downstream side. The conveyor 41 of the present embodiment is a screw conveyor that uses a motor 41a as a drive source, and is a weighing unit that automatically weighs roasted coffee beans. The amount of roasted coffee beans delivered can be controlled by the amount of rotation of the motor 41a (the amount of rotation of the screw). Each of the conveyors 41 discharges roasted coffee beans to the collecting and conveying path 42 on the downstream side. The collective conveyance path 42 is formed of a hollow member, includes an input port 42a for each conveyor 41 and a common discharge port 42b, and the roasted coffee beans are supplied to the crushing device 5 from the common discharge port 42b. It

<3-2. Crusher>
The crushing device 5 will be described with reference to FIGS. 3 and 4. FIG. 4 is a vertical sectional view of the crushing device 5. The crushing device 5 includes grinders 5</b>A and 5</b>B and a separating device 6. The grinders 5A and 5B are a mechanism for grinding roasted coffee beans supplied from the storage device 4. The grinders 5A and 5B have different grain sizes for grinding beans. The grinder 5A is a grinder for coarse grinding, and the grinder 5B is a grinder for fine grinding.

<3-2-1. Grinder>
The grinder 5A includes a motor 52a and a main body 53a. The motor 52a is a drive source of the grinder 5A. The main body 53a is a unit that houses a cutter, and has a rotary shaft 54a built therein. The rotating shaft 54a is provided with a gear 55a, and the driving force of the motor 52a is transmitted to the rotating shaft 54a via the gear 55a.

  The rotary shaft 54a is also provided with a rotary blade 58a which is a cutter, and a fixed blade 57a which is a cutter is provided around the rotary blade 58a. The inside of the main body 53a communicates with the inlet 50a and the outlet 51a. The roasted coffee beans supplied from the collecting/conveying path 42 laterally enter the main body 53a through an input port 50a formed on the side of the main body 53a, and are sandwiched between the rotary blade 58a and the fixed blade 57a. It is crushed as it is. A suppressing plate 56a is provided above the rotary blade 58a of the rotating shaft 54a, and the suppressing plate 56a suppresses roasted coffee beans from escaping to the upper side. In the grinder 5A, roasted coffee beans are crushed to, for example, about 1/4. The ground beans that have been crushed are discharged to the separation device 6 through the discharge port 51a.

  The roasted coffee beans supplied to the charging port 50a may be supplied to a height such that the roasted coffee beans hit the side surface, not from above the rotary blade 58a. In this case, the rotary blade 58a suppresses the roasted coffee beans from escaping to the upper side, and thus the suppression plate 56a need not be provided.

  The grinder 5A may change the size of the roasted coffee beans discharged after being crushed by changing the number of rotations of the rotary blade 58a. Alternatively, the distance between the rotary blade 58a and the fixed blade 57a may be changed by manually adjusting the distance.

  The separating device 6 is a mechanism for separating unnecessary substances from ground beans. The separating device 6 is arranged between the grinder 5A and the grinder 5B. That is, in the case of the present embodiment, the roasted coffee beans supplied from the storage device 4 are first coarsely ground by the grinder 5A, and unnecessary substances are separated from the coarsely ground beans by the separation device 6. The coarsely ground beans from which unnecessary substances are separated are finely ground by the grinder 5B. The unnecessary substances separated by the separation device 6 are typically chaff and fine powder. These may reduce the taste of coffee beverages. The separation device 6 is a mechanism for separating unnecessary substances by the suction force of air, and the details thereof will be described later.

  The grinder 5B includes a motor 52b and a main body 53b. The motor 52b is a drive source of the grinder 5B. The main body portion 53b is a unit that accommodates a cutter, and has a rotary shaft 54b built therein. A pulley 55b is provided on the rotary shaft 54b, and the driving force of the motor 52b is transmitted to the rotary shaft 54b via the belt 59b and the pulley 55b.

  The rotary shaft 54b is also provided with a rotary blade 58b, and the fixed blade 57b is provided above the rotary blade 58b. The inside of the main body 53b communicates with the inlet 50b and the outlet 51b. The ground beans falling from the separating device 6 enter the main body portion 53b through the charging port 50b and are further crushed so as to be sandwiched between the rotary blade 58b and the fixed blade 57b. The ground beans crushed into powder are discharged from the discharge port 51b. The grain size of the ground beans in the grinder 5B can be adjusted by adjusting the gap between the rotary blade 58b and the fixed blade 57b.

  The crushing of roasted coffee beans may be performed with one grinder (single-step crushing). However, as in the present embodiment, by performing the two-stage pulverization by the two grinders 5A and 5B, the grain size of the ground beans can be easily made uniform, and the extraction degree of the coffee liquid can be made constant. When crushing beans, heat may be generated due to friction between the cutter and the beans. By the two-step crushing, heat generation due to friction during crushing can be suppressed and deterioration of ground beans (for example, deterioration of flavor) can be prevented.

  In addition, by passing through the steps of coarse grinding→separation of unnecessary substances→fine grinding, the mass difference between the unnecessary substances and the ground beans (required part) can be increased when separating unnecessary substances such as chaff. This can improve the separation efficiency of the unwanted matter and prevent ground beans (necessary portion) from being separated as unwanted matter. In addition, the heat treatment of the ground beans can be suppressed by air cooling by interposing the separation process of the unwanted matter using the suction of air between the coarse grinding and the fine grinding. This can prevent deterioration of the ground beans (for example, deterioration of flavor).

<3-2-2. Separator>
Next, the separation device 6 will be described with reference to FIGS. FIG. 5 is a partially cutaway perspective view of the separating device 6. The separation device 6 includes a suction unit 6A and a forming unit 6B. The forming unit 6B is a hollow body that forms a separation chamber SC through which ground beans that freely fall from the grinder 5A pass. The suction unit 6A communicates with the separation chamber SC in a direction (in the present embodiment, the horizontal direction) that intersects the passage direction of the ground beans (the vertical direction in the present embodiment), and the air in the separation chamber SC is communicated. Is a unit for sucking. By sucking the air in the separation chamber SC, lightweight objects such as chaff and fine powder are sucked. As a result, unnecessary substances can be separated from the ground beans.

  The suction unit 6A is a centrifugal separation mechanism. The suction unit 6A includes a blower unit 60A and a collection container 60B. In the case of this embodiment, the blower unit 60A is a fan motor, and exhausts the air in the collection container 60B upward.

  The collection container 60B includes an upper portion 61 and a lower portion 62 that are separably engaged. The lower portion 62 has a bottomed cylindrical shape with an open upper portion, and forms a space for accumulating unnecessary substances. The upper portion 61 constitutes a lid portion that is attached to the opening of the lower portion 62. The upper portion 61 includes a cylindrical outer peripheral wall 61a and an exhaust pipe 61b formed coaxially with the outer peripheral wall 61a. The blower unit 60A is fixed to the upper portion 61 above the exhaust pipe 61b so as to suck the air in the exhaust pipe 61b. The upper portion 61 also includes a tubular connecting portion 61c extending in the radial direction. The connection portion 61c is connected to the forming unit 6B and connects the separation chamber SC and the recovery container 60B. The connecting portion 61c is open to the side of the exhaust pipe 61b.

  The airflow indicated by arrows d1 to d3 in FIG. 5 is generated by driving the blower unit 60A. Due to this air flow, air containing unnecessary substances is sucked from the separation chamber SC into the recovery container 60B through the connection portion 61c. Since the connecting portion 61c is open to the side of the exhaust pipe 61b, the air containing the unwanted matter swirls around the exhaust pipe 61b. The unwanted matter D in the air falls due to its weight and is collected in a part of the collection container 60B (deposited on the bottom surface of the lower portion 62). The air is exhausted upward through the inside of the exhaust pipe 61b.

  A plurality of fins 61d are integrally formed on the peripheral surface of the exhaust pipe 61b. The plurality of fins 61d are arranged in the circumferential direction of the exhaust pipe 61b. Each fin 61d is inclined with respect to the axial direction of the exhaust pipe 61b. By providing such fins 61, the swirling of air containing the unwanted matter D around the exhaust pipe 61b is promoted. Further, the fins 61 facilitate the separation of the unwanted matter D. As a result, the vertical length of the suction unit 6A can be suppressed, which contributes to downsizing of the device.

  In addition, in the present embodiment, the forming unit 6B is arranged in the drop path of the ground beans by the grinders 5A and 5B, while the suction unit 6A of the centrifugal separation method is arranged on the side of the drop path. Although the mechanism of the centrifugal separation system tends to be long in the vertical direction, the suction unit 6A is arranged laterally side by side with respect to the grinder 5A and the grinder 5B by arranging the suction unit 6A laterally while shifting it from the drop path. You can This contributes to suppressing the vertical length of the device. In particular, when performing two-stage pulverization by the two grinders 5A and 5B as in the present embodiment, the vertical length of the device tends to be long, and thus such arrangement of the suction unit 6A reduces the size of the device. It is effective for

  The forming unit 6B will be described with reference to FIGS. FIG. 6A is a vertical sectional view of the forming unit 6B. FIG. 7A is a perspective view and a partially enlarged view of the forming unit 6B. FIG. 8A is a plan view of the forming unit 6B and is a comparative explanatory diagram of cross-sectional areas.

  In the case of this embodiment, the forming unit 6B is formed by joining two members which are half-divided into upper and lower parts. The forming unit 6B includes a pipe portion 63 and a separation chamber forming portion 64, and has a spoon shape in a plan view. The tube portion 63 is a tubular body that forms a passage 63a to the suction unit 6A, and extends in the lateral direction (direction intersecting with a center line CL described later). The separation chamber forming portion 64 is a ring-shaped hollow body that is connected to the pipe portion 63 and forms the separation chamber SC, the center of which is vertically open.

  In the present embodiment, when separating the unnecessary material from the ground beans, a method is adopted in which the ground beans falling from the grinder 5A are subjected to a lateral wind pressure to suck the unnecessary materials. This is advantageous in that the length in the vertical direction can be made shorter than that of the centrifugal separation method.

  The separation chamber forming portion 64 includes a tubular portion 65 that extends in the vertical direction. The tubular portion 65 projects into the separation chamber SC from the central portion in the vertical direction to the lower portion. The tubular portion 65 has an opening portion 65a at one end on the upper side, and the opening portion 65a forms an input port for ground beans that communicates with the separation chamber SC. The opening 65a is located outside the separation chamber SC and is connected to the discharge port 51a of the grinder 5A. As a result, the ground beans that drop from the discharge port 51a are introduced into the separation chamber forming unit 64 without leakage. The tubular portion 65 has an opening 65b at the other end on the lower side. The opening 65b is located in the separation chamber SC. Since the opening 65b faces the separation chamber SC, the ground beans falling from the discharge port 51a are introduced into the separation chamber SC without leakage.

  In the case of the present embodiment, the tubular portion 65 has a cylindrical shape, and the openings 65a and 65b have concentric circular shapes located on the center line CL. As a result, the ground beans falling from the discharge port 51a easily pass through the tubular portion 65. The tubular portion 65 has a tapered shape in which the cross-sectional area of the internal space gradually decreases from the opening 65a side toward the opening 65b side. Since the inner wall of the tubular portion 65 has a mortar shape, falling ground beans are likely to collide with the inner wall. In the ground beans falling from the grinder 5A, the grains may come into close contact with each other and fall as a lump. If the ground beans are in a lump state, the separation efficiency of unnecessary substances may decrease. In the case of the present embodiment, the ground beans that have become a lump collide with the inner wall of the tubular portion 65, so that the lump can be broken down and unnecessary substances can be easily separated.

  Note that the inner wall of the tubular portion 65 is not limited to the mortar shape in terms of breaking the lump of ground beans. There is a portion in the middle of the tubular portion 65 where the cross-sectional area of the internal space is smaller than that of the opening portion 65a, so that if there is an inner wall inclined (not horizontal) with respect to the center line CL, collision with a lump will occur. The ground beans can be smoothly dropped while promoting. Further, the tubular portion 65 does not need to project into the separation chamber SC, and may have only a portion projecting upward from the outer surface of the separation chamber forming portion 64.

  However, by projecting the tubular portion 65 into the separation chamber SC, the wind speed at the bypass portion R1 around the tubular portion 65 can be improved, and the effect of separating the unwanted matter by the wind pressure can be enhanced.

  The separation chamber forming unit 64 has a discharge port 66 communicating with the separation chamber SC, through which ground beans after separating unnecessary substances are discharged. In the case of the present embodiment, the discharge port 66 is located below the opening portion 65b, and the ground beans that have passed through the tubular portion 65 pass through the separation chamber SC and fall freely from the discharge port 66. In the case of this embodiment, the discharge port 66 is a circular opening located on the center line CL, and is an opening that is concentric with the openings 65a and 65b. Therefore, the ground beans easily pass through the separation chamber forming portion 64 by free fall, and it is possible to prevent the ground beans from accumulating in the separation chamber forming portion 64.

  As shown in FIG. 8A, in the case of the present embodiment, the cross-sectional area SC2 of the discharge port 66 is larger than the cross-sectional area SC1 of the opening 65b. In the case of this embodiment, the opening 65b and the discharge port 66 are overlapped with each other when viewed in the vertical direction. Therefore, when the opening portion 65b is projected in the up-down direction with respect to the discharge port 66, the opening portion 65b fits inside the discharge port 66. In other words, the opening 65b fits within the region where the discharge port 66 is extended in the vertical direction. A configuration in which the opening 65b and the discharge port 66 are not on the same center line but overlap each other, or a configuration in which at least one of them is not circular but overlap each other can be adopted.

  The ratio of the sectional area SC1 to the sectional area SC2 is, for example, 95% or less, or 85% or less, and, for example, 60% or more, or 70% or more. Since the opening 65b and the discharge port 66 are concentric circles, they overlap each other when viewed in the direction of the center line CL. Therefore, the ground beans that freely fall from the opening 65b are easily discharged from the discharge port 66. It is also possible to prevent falling ground beans from colliding with the edge of the discharge port 66 and bouncing toward the pipe portion 63 side, and it is possible to prevent necessary ground beans from being sucked by the suction unit 6A. Although it has been illustrated that the opening area of the one-end opening (for example, 65a) is smaller than the opening area of the discharge opening (for example, 66), the opening area of the discharge opening (for example, 66) and the opening area of the one-end opening (for example, 65a). The area may be the same, or the opening area of the one-end opening portion (eg 65a) may be larger than the opening area of the discharge port (eg 66). Although it has been illustrated that the opening area of the other end opening (eg 65b) is smaller than the opening area of the discharge opening (eg 66), the opening area of the discharge opening (eg 66) and the other end opening (eg 65b) May have the same opening area, or the opening area of the other end opening (eg, 65b) may be larger than the opening area of the discharge port (eg, 66). Although it has been illustrated that the suction unit (for example, 6A) sucks air from the discharge port 66 and the input port (for example, 65a, 65a′), the amount of air sucked from the input port (for example, 65a, 65a′) The amount of air sucked from the outlet 66 may be increased. This is achieved because the other end opening (for example, 65b) protrudes into the separation chamber and the cross-sectional area of the discharge port 66 is larger than the opening area size of the one end opening (for example, 65a). It may be realized by making the cross-sectional area of the discharge port 66 larger than the size of the opening area of the other end opening (eg 65b), or from the one end opening (eg 65a) to the separation chamber. The distance from the discharge port 66 to the separation chamber may be shorter than the distance to the separation chamber, or the distance from the discharge port 66 to the exhaust pipe 61b may be larger than the distance from the one end opening (for example, 65a) to the exhaust pipe 61b. It may be realized by a short distance, or may be realized by a distance from the outlet 66 to the blower unit 60A being shorter than a distance from the one end opening (for example, 65a) to the blower unit 60A. Any of the inner wall portions of the forming unit 6B and the members (63 to 65) forming the separation chamber SC, the cylindrical portion 65, and the other end opening portion (for example, 65b), but at least one of the grinders (5A and 5B) ) Directly or indirectly through another member, and the vibration due to the rotation of the grinder is transmitted and vibrates. For example, in the case of the beverage manufacturing apparatus 1 according to the embodiment, since they are in direct or indirect contact with each other, during the operation of the grinder, the members (63 to 65) forming the forming unit 6B and the separation chamber SC are operated. Any one of the inner wall portions, the tubular portion 65, or the other end opening (for example, 65b) vibrates, and the turbulent air generated in the separation chamber SC due to the vibration causes the other end opening (for example, 65b) to move to the separation chamber SC. A brake is applied to a light unwanted object that enters so that the unwanted object can be easily sucked by a suction unit (for example, 6A). In particular, the forming unit 6B as in the beverage manufacturing apparatus 1 in the embodiment is in direct contact with the grinder 5A of the grinder 5A and the grinder 5B, but by directly contacting one grinder in this manner, the forming unit 6B is formed. You may give moderate vibration to and make it easy to suck a light unnecessary thing.

  In the case of the present embodiment, the air sucked by the suction unit 6A is mainly sucked from the discharge port 66. Therefore, a gap is provided between the discharge port 66 and the input port 50b of the grinder 5B, and the suction of air is promoted. That is, in the present embodiment, the discharge port 66 not only discharges the ground beans but also functions as an air intake port for taking in air from outside the forming unit 6B into the separation chamber SC. Although it is possible to provide an air intake port in addition to the exhaust port 66 (for example, the side portion of the forming unit 6B), the size of the device can be reduced by also using the air intake port 66. In FIG. 6A, the arrow d4 schematically shows the direction of the air flow of the air sucked by the suction unit 6A. By sucking air from the discharge port 66, unnecessary substances are less likely to be discharged from the discharge port 66, and the performance of separating ground beans and unnecessary substances can be improved. The air sucked by the suction unit 6A can also be sucked from the opening 65a.

  The bypass portion R1 in the present embodiment is formed beside (around) the tubular portion 65 by the wall portion 64a forming the forming unit 6B. The wall portion 64a has a shape obtained by rotating an arc around the center line CL, and the bypass portion R1 formed by the wall portion 64a is C-shaped in plan view (line of sight in the center line CL direction). It is a donut-shaped space.

  The air taken into the separation chamber SC from the exhaust port 66 includes air that directly goes to the passage 63a as shown by an arrow d41 and air that goes to the passage 63a via the bypass R1 as shown by an arrow d42. .. By detouring the bypass portion R1 with air, a region R2, which is a spot where an unwanted object flies, is generated at the ground bean drop position.

  That is, the presence of the bypass R1 makes it difficult for air to flow in a straight line from the outlet 66 to the passage 63a with a strong force. Specifically, the air (arrow d42) flowing from the discharge port 66 to the passage 63a via the bypass R1 and the air pulled from the bypass R1 to the passage 63a to rise from the discharge port 66 The air (arrow d41) flowing from the outlet 66 to the passage 63a is dispersed in the region R2, and a weak air flow is generated around the region R2. Therefore, relatively heavy ground beans fall and a relatively light chaff is unnecessary. The substance is entrained in the air flowing from the discharge port 66 to the passage 63a and sent to the passage 63a. For this reason, it is possible to efficiently separate only the unnecessary substances without making the distance between the opening 65b and the discharge port 65 long, and it is possible to make the forming unit 6B and the separating device 6 as a whole compact. There is.

  Further, the bypass portion R1 includes a portion R1' at a position opposite to the tube portion 63 and the suction unit 6A in the lateral direction with respect to the cylinder upper portion 65. In the region R1' far from the pipe portion 63 and the suction unit 6A, the effect of separating the unwanted matter due to the wind pressure can be enhanced, or the detour distance can be lengthened to enhance the effect of separating the levitation effect.

<3-2-3. Other configuration examples>
A turbulent portion may be provided that disturbs the flow of air taken into the separation chamber SC from the outlet 66 and promotes the generation of turbulent flow. 6B and 7B show an example thereof. In the illustrated example, the disturbing portion 67 is formed on the peripheral wall that defines the discharge port 66. The disturbing portion 67 causes a turbulent flow in the air sucked from the outlet 66 into the separation chamber SC. By forming the disturbing portion 67, a turbulent flow is likely to occur particularly in the region R2 between the opening 65b and the discharge port 66. Further, in the case of the present embodiment, since the wind speed is improved in the bypass portion R1 around the tubular portion 65, it is possible to synergistically promote the generation of turbulent flow in the region R2.

  The ground beans introduced into the introduction port 65a are agitated under the influence of turbulent flow when passing through the region R2. In the case of the present embodiment, in particular, since the cross-sectional area SC2 of the discharge port 66 is larger than the cross-sectional area SC1 of the opening 65b as described above, the ground beans always pass through the region R2. Turbulence facilitates the separation of unwanted material such as chaff and fines from ground beans. Therefore, even if the separation chamber SC is a small space, it is possible to improve the efficiency of separating undesired substances, and in particular, it contributes to the reduction of the vertical length of the separation chamber SC, as in the present embodiment. This is advantageous for downsizing the device when two-stage grinding is performed with the two grinders 5A and 5B.

  In the case of this embodiment, the disturbing portion 67 includes a plurality of turbulent flow promoting elements 67a. The turbulent flow promoting element 67a is a protrusion that protrudes downward in the vertical direction. The turbulent flow promoting element 67a may be projected in any direction, but a direction within the range from the downward direction to the radially inward direction is preferable in that turbulent flow is more easily generated in the separation chamber SC. is there. If the protruding direction is downward as in this embodiment, the ground beans that have fallen are not caught, which is more preferable.

  The cross-sectional shape of the turbulent flow promoting element 67a is such that a trapezoidal quadrangular prism is arranged so that the upper base of the cross section faces the centerline CL direction, and a chamfer 67b is provided on the inner side of the tip end portion. The shape of the turbulent flow promoting element 67a is not limited to the shape of this embodiment, but a shape that makes the shape of the discharge port 66 three-dimensionally complicated is preferable.

  In the case of the present embodiment, the turbulent flow promoting element 67a is repeatedly formed in the circumferential direction d5 of the discharge port 66. As a result, air is blown into the region R from multiple directions to promote the generation of turbulence. The pitches of the adjacent turbulent flow promoting elements 67a may be different pitches, but are equal pitches in this embodiment. Although twelve turbulent flow promoting elements 67a are formed, the number of turbulent flow promoting elements 67a is arbitrary.

  Next, the disturbing portion 67 may be provided in a place other than the discharge port 66, and may be a portion outside the forming unit 6B as long as it disturbs the flow of the air taken into the discharge port 66. The example of FIG. 8B shows an example in which the disturbing portion 67 is formed on the peripheral wall forming the input port 50b of the grinder 5B. Even if it is provided in the unit near the discharge port 66 or in the opening portion facing the discharge port 66 like this input port 50b, the flow of the air taken into the discharge port 66 may be disturbed. As described above, the disturbing portion 67 may be provided in the unit outside the discharge port 66, or the disturbing portion 67 may be formed in a unit separate from the forming unit 6B.

  Further, the disturbing portion 67 may be formed in the discharge port 66 and may be provided in a place other than the discharge port 66. For example, as shown in FIG. 8C, the disturbing portion 67 is formed in the discharge port 66. Alternatively, it may be formed at the charging port 50b.

  It should be noted that the place where the disturbing portion 67 is provided in the forming unit 6B may be the opening 65a or the opening 65b provided as an air intake port instead of the outlet 66, and the side portion of the forming unit 6B (for example, the portion R1′). An air intake port may be provided in the wall portion 64a) adjacent to, and a disturbing portion 67 may be provided therein. Further, a plurality of air intake ports may be provided including the exhaust port 66 and the like, and the disturbing portion 67 may be formed in all or part of the air intake ports.

  Another configuration example of the separation chamber forming unit 64 will be described with reference to FIG. 9. The turbulent flow promoting element 67a may be not only a protrusion but also a notch or a hole. The example EX1 of FIG. 9 illustrates an example in which the turbulent flow promoting element 67a is a through hole formed in the peripheral wall of the discharge port 66. Such holes can also promote the generation of turbulence in the region R2.

  The example of EX2 in FIG. 9 shows an example in which the tubular portion 65 is not provided. Also in this case, it is preferable that the cross-sectional area SC2 of the outlet 66 is larger than the cross-sectional area SC1' of the inlet 65a'. Further, the detour portion R1 is formed by a plate-shaped wall portion 64b. In this way, the bypass portion R1 may be formed in a configuration different from that of the tubular portion 65, and further, the bypass portion R1 may be formed by a unit such as a tube that is separate from the forming unit 6B.

  The opening 65b of the tubular portion 65 may be an opening on an inclined surface instead of an opening on a horizontal plane. In the example of EX3 in FIG. 9, the lower end of the tubular portion 65 on the pipe portion 63 side projects downward more than the lower end on the opposite side. By doing so, the ground beans can be easily guided to the bypass portion R1 side, the residence time of the ground beans in the separation chamber SC can be made longer, and the separation effect can be enhanced.

<4. Drive unit and extraction container>
<4-1. Overview>
The drive unit 8 and the extraction container 9 of the extraction device 3 will be described with reference to FIG. FIG. 10 is a perspective view of the drive unit 8 and the extraction container 9.

  The drive unit 8 is supported by the frame F. The frame F includes upper and lower beam portions F1 and F2 and a column portion F3 that supports the beam portions F1 and F2. The drive unit 8 is roughly divided into three units, an upper unit 8A, a middle unit 8B, and a lower unit 8C. The upper unit 8A is supported by the beam portion F1. The middle unit 8B is supported by the beam portion F1 between the beam portion F1 and the beam portion F2. The lower unit 8C is supported by the beam portion F2.

  The extraction container 9 is a chamber including a container body 90 and a lid unit 91. The extraction container 9 may be called a chamber. The middle unit 8B includes an arm member 820 that detachably holds the container body 90. The arm member 820 includes a holding member 820a and a pair of left and right shaft members 820b. The holding member 820a is an elastic member such as a resin formed in a C-shaped clip shape, and holds the container body 90 by its elastic force. The holding member 82a holds the left and right side portions of the container body 90, and the front side of the container body 90 is exposed. This makes it easier to visually recognize the inside of the container body 90 in a front view.

  The container body 90 is attached to and detached from the holding member 820a by a manual operation, and the container body 90 is attached to the holding member 820a by pressing the container body 90 to the holding member 820a rearward and rearward. Further, the container body 90 can be separated from the holding member 820a by pulling out the container body 90 from the holding member 820a to the front side in the front-rear direction.

  The pair of shaft members 820b are rods extending in the front-rear direction, and are members that support the holding member 820a. Although the number of the shaft members 820b is two in the present embodiment, it may be one, or three or more. The holding member 820a is fixed to the front ends of the pair of shaft members 820b. By a mechanism described later, the pair of shaft members 820b are moved forward and backward, the holding member 820a is moved forward and backward, and the container main body 90 can be moved in parallel in the forward and backward directions. The middle unit 8B can also perform a turning operation to turn the extraction container 9 upside down, as will be described later.

<4-2. Extraction container>
The extraction container 9 will be described with reference to FIGS. 11 and 12. FIG. 11 is a view showing a closed state and an open state of the extraction container 9, and FIG. 12 is an exploded perspective view of the extraction container 9. As described above, the extraction container 9 is turned upside down by the middle unit 8B. The extraction container 9 in FIGS. 10 and 11 shows a basic posture in which the lid unit 91 is located on the upper side. In the following description, the vertical positional relationship means the vertical positional relationship in the basic posture unless otherwise specified.

  The container body 90 is a bottomed container, and has a bottle shape having a neck portion 90b, a shoulder portion 90d, a body portion 90e, and a bottom portion 90f. The whole or a part of the container body 90 may have a transparent portion. The transparent portion may be made of a colorless transparent material or a colored transparent material. This allows the inside of the container body 90 to be visually recognized. A flange portion 90c that defines an opening 90a that communicates with the internal space of the container body 90 is formed at the end of the neck portion 90b (upper end portion of the container body 90).

  Both the neck portion 90b and the body portion 90e have a cylindrical shape. In the neck portion 90b, a region having the same sectional area or sectional shape of the internal space extends in the vertical direction. Further, the body portion 90e also has a region having the same cross-sectional area or cross-sectional shape extending in the vertical direction, and is longer than the neck portion 90b. The trunk 90e has a larger cross-sectional area than the neck 90b. The ratio of the cross-sectional area of the neck portion 90b to the body portion 90e is, for example, 65% or less, 50% or less, or 35% or less, and, for example, 10% or more, or 20% or more. The shoulder portion 90d is a portion between the neck portion 90b and the body portion 90e, and has a tapered shape such that the cross-sectional area of the internal space thereof gradually decreases from the body portion 90e side toward the neck portion 90b side. ing. However, the neck portion 90b is merely named for the position closer to the opening 90a than the bottom portion 90f, and the cross-sectional area of the internal space is not necessarily limited to that larger in the trunk portion 90e than in the neck portion 90b. Alternatively, the neck portion 90a may be a part of the body portion 90e. That is, the extraction container 9 may not have a shape having a constricted portion as shown in FIG. 10 or the like, and may have a hollow shape or a hollow shape and a flange portion such as 90c is provided in the vicinity of the opening 90a or the opening 90a. It may have a different shape.

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

  The container body 90 includes a body member 900 and a bottom member 901. The main body member 900 is a tubular member that forms the neck portion 90b, the shoulder portion 90d, and the body portion 90e and is open at the top and bottom. The bottom member 901 is a member that forms the bottom portion 90f, and is inserted and fixed to the lower portion of the main body member 900. A seal member 902 is interposed between the main body member 900 and the bottom member 901 to improve airtightness inside the container main body 90.

  A convex portion 901c is provided at the center of the bottom member 901, and a shaft hole 901b is formed in the convex portion 901c. A plurality of communication holes 901a are formed around the shaft hole 901b. The communication hole 901a is a through hole that allows the inside of the container body 90 to communicate with the outside, and is mainly used for discharging a waste liquid and a residue when cleaning the inside of the container body 90.

  The shaft hole 901b penetrates the bottom member 901, and the shaft 903a of the plug member 903 is inserted therein. The plug member 903 opens and closes the communication hole 901a from the inside of the container body 90. A seal member 904 is provided between the plug member 903 and the inner surface (upper surface) of the bottom member 901 to improve airtightness inside the container body 90 when the plug member 903 is closed.

  On the outer side (lower side) of the bottom member 901, a coil spring 905 and a cylindrical spring receiver 906 are attached to the shaft 903a, and an E ring 907 is engaged with the end of the shaft 903a. The coil spring 905 and the spring receiver 906 are held between the bottom member 901 and the E ring 907, and the coil spring 905 biases the plug member 903 in the closing direction. A seal member 908 is provided on the convex portion 901c, and the seal member 908 is a member for maintaining an airtight space between the upper unit 8A or the lower unit 8C and the bottom member 901.

  The lid unit 91 includes a hat-shaped base member 911. The base member 911 has a protrusion 911d and a flange 911c that overlaps the flange 90c when closed. The base member 911 is provided with the same opening/closing mechanism as the stopper member 903 in the container body 90. Specifically, a shaft hole 911b is formed in the center of the base member 911, and a plurality of communication holes 911a are formed around the shaft hole 911b. The communication hole 911a is a through hole that allows the inside of the container body 90 to communicate with the outside, and is mainly used for injecting hot water into the container body 90 and delivering a coffee beverage.

  The shaft hole 911b penetrates the base material 911, and the shaft 913a of the plug member 913 is inserted therein. The plug member 913 opens and closes the communication hole 911 a from the inside of the container body 90. A seal member 914 is provided between the plug member 913 and the inner surface of the base member 911 to improve the airtightness inside the container body 90 when the plug member 913 is closed.

  On the outside (upper side) of the base member 911, a coil spring 915 and a cylindrical spring receiver 916 are attached to the shaft 913a, and an E ring 917 engages with the end of the shaft 913a. The coil spring 915 and the spring receiver 916 are held between the base member 911 and the E ring 917, and the coil spring 915 biases the plug member 913 in the closing direction. The protrusion 911d is provided with a seal member 918a and a ring spring 918b.

  The fixing member 919 is fixed to the inner side (lower side) of the base member 911. The fixing member 919 supports the filter 910 and the holding member 910a. The filter 910 is a filter for separating the residue of coffee drink and ground beans, and is, for example, a metal filter. By using the metal filter, a coffee beverage containing coffee oil can be provided to the user. The holding member 910a is a porous member that suppresses the deformation of the filter 910. The seal member 919a is supported by the fixed member 919. In the case of the present embodiment, the fixing member 919 is an elastic member, and the fixing member 919 and the sealing member 919a improve the airtightness between the lid unit 91 and the container body 90 when the lid unit 91 is closed.

  It is also possible to adopt a configuration in which the seal member 919a is not used by airtightly contacting the flange 90c and the flange 911c.

<4-3. Upper unit and lower unit>
The upper unit 8A and the lower unit 8C will be described with reference to FIGS. 13 and 14. 13 is a front view showing a part of the configuration of the upper unit 8A and the lower unit 8B, and FIG. 14 is a sectional view taken along the line I-I of FIG.

  The upper unit 8A includes an operation unit 81A. The operation unit 81A performs opening/closing operation (elevation) of the lid unit 91 with respect to the container body 90 and opening/closing operation of the plug members 903 and 913. The operation unit 81A includes a support member 800, a holding member 801, a lifting shaft 802, and a probe 803.

  The supporting member 800 is fixedly provided so that the relative position with respect to the frame F does not change. It includes a housing portion 800b that houses the holding member 801. The accommodating portion 800b is a cylindrical space that opens downward and has a closed top. The support member 800 also includes a communication portion 800a that connects the pipe L3 and the inside of the storage portion 800b. Hot water, tap water, and atmospheric pressure supplied from the pipe L3 are introduced into the housing portion 800b through the communication portion 800a.

  The holding member 801 is a member that holds the lid unit 91 detachably. The holding member 801 includes a housing portion 801b into which the convex portion 911d of the lid unit 91 or the convex portion 901c of the bottom member 901 is inserted. The accommodating portion 801b is a cylindrical space that opens downward and has a closed top. The holding member 801 also includes a storage portion 800b and a communication portion 801a that connects the storage portion 801b. Hot water, tap water, and atmospheric pressure supplied from the pipe L3 are introduced into the accommodation portion 801b through the communication portion 800a and the communication portion 801a. The holding member 801 is a movable member provided so as to be slidable in the up-down direction inside the housing portion 800b. The holding member 801 is formed with a seal member 801c that seals between the holding member 801 and the housing portion 800b, and the airtightness inside the housing portion 800b is maintained even while the holding member 801 is sliding.

  An engagement portion 801d is formed on the inner wall of the accommodation portion 801b so as to protrude inward in the radial direction. The lid unit 91 is held by the holding member 801 by engaging the engaging portion 801d and the ring spring 918b of the lid unit 91. When a force of a certain amount or more that separates the holding member 801 and the lid unit 91 in the vertical direction is applied, the engagement between the engagement portion 801d and the ring spring 918b is released due to the elastic deformation of the ring spring 918b. As a result, the lid unit 91 and the holding member 801 are separated.

  The lifting shaft 802 is provided so that its axial direction is the vertical direction. The elevating shaft 802 penetrates the top of the support member 800 in the vertical direction, and is provided so as to be vertically movable with respect to the support member 800. The supporting member 800 is provided with a seal member 800c in a hole portion through which the elevating shaft 802 passes, so that the airtightness inside the housing portion 800b is maintained even while the elevating shaft 802 is sliding.

  The top of the holding member 801 is fixed to the lower end of the elevating shaft 802. The holding member 801 slides in the vertical direction as the lifting shaft 802 moves up and down, so that the holding member 801 can be attached to and detached from the protrusions 911d and 901c. Further, the lid unit 91 can be opened and closed with respect to the container body 90. FIG. 15 shows a case where the lid unit 91 is in the open state. The holding member 801 holding the lid unit 91 is in the raised position, and the held lid unit 91 is separated above the container body 90. Note that in FIG. 15, some of the components are not shown.

  A screw 802 a forming a lead screw mechanism is formed on the outer peripheral surface of the elevating shaft 802. A nut 804b is screwed onto the screw 802a. The upper unit 8A includes a motor 804a, and the nut 804b is rotated in place (without moving up and down) by the driving force of the motor 804a. The lifting shaft 802 moves up and down by the rotation of the nut 804b.

  The elevating shaft 802 is a tubular shaft having a through hole in its central axis, and a probe 803 is vertically slidably inserted into this through hole. The probe 803 vertically penetrates the top of the holding member 801, and is provided so as to be vertically movable with respect to the support member 800 and the holding member 801. The holding member 801 is provided with a seal member 801e in a hole portion through which the probe 803 passes, so that the airtightness inside the housing portion 801b is maintained even while the probe 803 is sliding.

  The probe 803 is provided coaxially with the shaft 903a of the plug member 903 (and the shaft 913a of the plug member 913). By lowering the probe 803, the shaft 903a of the plug member 903 can be pressed downward, and the plug member 903 can be changed from the closed state to the open state. Instead of using the probe 803, it is possible to use the atmospheric pressure of the air or the water pressure of the water supplied to the extraction container 9 to press the plug member 903 to change it from the closed state to the open state. In this case, the atmospheric pressure or water pressure may be higher than the biasing force of the coil spring 905.

  FIG. 16 shows an opening/closing manner of the plug member 903 (and the plug member 913). The holding member 801 is in the lowered position, and the convex portion 911d is inserted into the holding member 801. It is understood that the stopper member 903 can be displaced to the open state indicated by the broken line by lowering the probe 803 (not shown in FIG. 16). When the extraction container 9 is turned upside down, the plug member 913 can be changed from the closed state to the open state. Note that FIG. 16 omits illustration of some of the components.

  A screw 803a forming a lead screw mechanism is formed on the outer peripheral surface of the probe 803. A nut 805b is screwed onto the screw 803a. The upper unit 8A includes a motor 805a, and the nut 805b is provided so as to rotate on the spot (without moving up and down) by the driving force of the motor 805a. The probe 803 moves up and down by the rotation of the nut 805b.

  The lower unit 8C includes an operation unit 81C. The operation unit 81C has a configuration in which the operation unit 81A is turned upside down, and opens and closes the plug members 903 and 913. The operation unit 81C is also configured to open and close the lid unit 91, but in the present embodiment, the operation unit 81C is not used to open and close the lid unit 91.

  Although the operation unit 81A is substantially the same as the description below, 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 provided so that the relative position with respect to the frame F does not change. It includes a housing portion 810b that houses the holding member 811. The accommodating portion 810b is a cylindrical space that opens upward and has a closed bottom. The support member 810 also includes a communication portion 810a that connects the switching valve 10a of the switching unit 10 and the inside of the storage portion 810b. Residues of coffee drink, tap water, and ground beans in the container body 90 are introduced into the switching valve 10a via the communication portion 810a.

  The holding member 811 includes a housing portion 811b into which the convex portion 911d of the lid unit 91 or the convex portion 901c of the bottom member 901 is inserted. The accommodating portion 811b is a cylindrical space that opens upward and has a closed bottom. The holding member 811 also includes a communication portion 811a that allows the storage portion 810b and the storage portion 811b to communicate with each other. Residues of coffee drink, tap water, and ground beans in the container body 90 are introduced into the switching valve 10a via the communication parts 810a and 811b. The holding member 811 is a movable member that is provided so as to be slidable in the up and down direction inside the housing portion 810b. The holding member 811 is formed with a seal member 811c that seals between the holding member 811 and the housing portion 810b, and the airtightness inside the housing portion 810b is maintained even while the holding member 811 is sliding.

  An engagement portion 811d is formed on the inner wall of the accommodation portion 811b, the engagement portion 811d protruding inward in the radial direction. The lid unit 91 is held by the holding member 811 by engaging the engaging portion 811d and the ring spring 918b of the lid unit 91. When a force of a certain amount or more that separates the holding member 811 and the lid unit 91 in the vertical direction is applied, the engagement between the engaging portion 811d and the ring spring 918b is released due to the elastic deformation of the ring spring 918b. As a result, the lid unit 91 and the holding member 811 are separated.

  The lifting shaft 812 is provided so that its axial direction is the vertical direction. The elevating shaft 812 penetrates the bottom of the support member 810 in the vertical direction, and is provided so as to be vertically movable with respect to the support member 810. The supporting member 810 is provided with a seal member 810c in a hole portion through which the elevating shaft 812 passes, so that the airtightness inside the housing portion 810b is maintained even while the elevating shaft 812 slides.

  The bottom of the holding member 811 is fixed to the lower end of the lifting shaft 812. The holding member 811 slides in the vertical direction as the lifting shaft 812 moves up and down, so that the holding member 811 can be attached to and separated from the protrusions 901c and 911d. A screw 812a forming a lead screw mechanism is formed on the outer peripheral surface of the elevating shaft 812. A nut 814b is screwed onto the screw 812a. The lower unit 8C includes a motor 814a, and the nut 814b is rotated in place (without moving up and down) by the driving force of the motor 814a. The lifting shaft 812 moves up and down by the rotation of the nut 814b.

  The elevating shaft 812 is a tubular shaft having a through hole in the center axis, and the probe 813 is vertically slidably inserted into the through hole. The probe 813 penetrates the bottom portion of the holding member 811 in the vertical direction, and is provided so as to be vertically movable with respect to the support member 810 and the holding member 811. The holding member 811 is provided with a seal member 811e in a hole portion through which the probe 813 passes, so that the airtightness inside the housing portion 811b is maintained even while the probe 813 slides.

  The probe 813 is provided coaxially with the shaft 913a of the plug member 913 (and the shaft 903a of the plug member 903). By raising the probe 813, the shaft 913a of the plug member 913 can be pressed upward, and the plug member 913 can be changed from the closed state to the open state. Instead of using the probe 813, it is also possible to press the stopper member 913 by using the atmospheric pressure of the air or the water pressure of the water supplied to the extraction container 9 to change it from the closed state to the open state. In this case, the atmospheric pressure or water pressure may be higher than the biasing force of the coil spring 915. For example, at least one or both of charging a liquid for steaming (for example, hot water) and charging liquid for cleaning the extraction container 9 (for example, purified water, hot water, detergent) is a liquid charging portion (plug member). 913 or the plug member 903) is not opened in advance and the liquid is press-fitted, but the user's preference, how the liquid is shown to the user through the transmissive portion 101, and the degree of the liquid force are different from usual. In order to do so, it may be preferable to close the opening (the plug member 913 or the plug member 903) or open the opening less than the full opening, and then open the opening by the water pressure of the liquid to be introduced. For example, the liquid may momentarily enter the extraction container 9 or may be poured onto the shower on the inner wall portion of the extraction container 9 or the extraction target (for example, ground coffee beans of roasted coffee).

  FIG. 16 shows an opening/closing state of the plug member 913 (and the plug member 903). The holding member 811 is in the raised position, and the convex portion 901c is inserted in the holding member 811. It is understood that the stopper member 913 can be displaced to the open state indicated by the broken line by raising the probe 813 (not shown in FIG. 16). When the extraction container 9 is turned upside down, the stopper member 903 can be changed from the closed state to the open state.

  A screw 813a forming a lead screw mechanism is formed on the outer peripheral surface of the probe 813. A nut 815b is screwed onto the screw 813a. The lower unit 8C includes a motor 815a, and the nut 815b is provided so as to be rotated in place (without moving up and down) by the driving force of the motor 815a. The rotation of the nut 815b moves the probe 813 up and down.

<4-4. Chubu Unit>
The middle unit 8B will be described with reference to FIGS. 10 and 17. FIG. 17 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 lock mechanism 821 in addition to the arm member 820 described above.

  The lock mechanism 821 is a mechanism that keeps the lid unit 91 closed with respect to the container body 90. The lock mechanism 821 includes a pair of gripping members 821a that vertically clamps the flange portion 911c of the lid unit 91 and the flange portion 90c of the container body 90. The pair of gripping members 821a have a C-shaped cross section in which the flange portion 911c and the flange portion 90c are sandwiched and fitted, and are opened and closed in the left-right direction by the driving force of the motor 822. When the pair of gripping members 821a are in the closed state, as shown by the solid lines in the surrounding view of FIG. 17, each gripping member 821a fits the flange portion 911c and the flange portion 90c by vertically sandwiching them, The unit 91 is hermetically locked to the container body 90. In this locked state, the lid unit 91 does not move (the lock is not released) even if the holding unit 801 is lifted by the elevating shaft 802 to open the lid unit 91. That is, the locking force of the lock mechanism 821 is set to be stronger than the force of opening the lid unit 91 using the holding member 801. As a result, it is possible to prevent the lid unit 91 from being opened with respect to the container body 90 in the event of an abnormality.

  When the pair of gripping members 821a is in the open state, as shown by the broken line in the surrounding view of FIG. 17, the gripping members 821a are separated from the flange portion 911c and the flange portion 90c, and the lid unit 91 and the container body 90 are separated. And are unlocked.

  Note that the C-shaped cross section of the gripping member 821a is rectangular (the upper side and the lower side are parallel) in the example of the drawing, but may be trapezoidal in which the cross-sectional area becomes narrower on the opening end side. Thereby, the flange portion 911c and the flange portion 90c can be locked more firmly.

  When the engaging portion 801d of the holding member 801 and the ring spring 918b of the lid unit 91 are in the engaged state, and when the holding member 801 is raised from the lowered position to the raised position, the pair of gripping members 821a is in the opened state. The lid unit 91 is separated from the container body 90. On the contrary, when the pair of gripping members 821a is in the closed state, the engagement between the engaging portion 801d and the ring spring 918b is released, and only the holding member 801 moves up.

  The middle unit 8B also includes a mechanism that horizontally moves the arm member 820 in the front-rear direction using the motor 823 as a drive source. As a result, the container body 90 supported by the arm member 820 can be moved between the rear extraction position (state ST1) and the front bean insertion position (state ST2). FIG. 18 shows a movement mode of the container body 90. In FIG. 18, the position of the container body 90 shown by the solid line shows the extraction position, and the position of the container body 90 shown by the broken line is the bean charging position. The bean charging position is a position where the ground beans are charged into the container body 90, and the ground beans ground by the grinder 5B are charged into the opening 90a of the container body 90 from which the lid unit 91 is separated. The extraction position is a position where the container body 90 can be operated by the operation unit 81A and the operation unit 81C, is a position coaxial with the probes 803 and 813, and is a position for extracting the coffee liquid. 10 and 13 to 16 show the case where the container body 90 is in the extraction position. In this way, by changing the position of the container body 90 between the addition of ground beans and the extraction of coffee liquid and the supply of water, the steam generated during coffee liquid extraction causes the grinder 5B serving as the ground bean supply unit. It becomes difficult for the ground beans to adhere to the discharge port 51b, and it is possible to prevent the ground beans from adhering to the discharge port 51b due to the water content of the steam.

  Returning to FIG. 17, the middle unit 8B also includes a mechanism that rotates the support unit 81B around the shaft 825 in the front-rear direction using the motor 824 as a drive source. As a result, the posture of the container body 90 (extraction container 9) can be changed from the upright posture (state ST1) in which the neck portion 90b is upward to the inverted posture (state ST3) in which the neck portion 90b is downward. FIG. 13 shows the extraction container 9 in an upright posture. FIG. 19 illustrates a state in which the extraction container 9 is rotated to change its posture. While the extraction container 9 is rotating, the lock mechanism 821 keeps the lid unit 91 locked to the container body 90. The extraction container 9 shown by the solid line in FIG. 19 shows the state of the inverted posture, and the extraction container 9 shown by the broken line shows the intermediate posture between the upright posture and the inverted posture (the posture in the middle of rotation). The extraction container 9 is turned upside down in the upright posture and the inverted posture. In the upright posture, the convex portion 911d is located at the position of the convex portion 901c in the upright posture. Further, the convex portion 901c is located in the inverted posture at the position of the convex portion 911d in the upright posture. Therefore, in the inverted posture, the operation unit 81A can perform the opening/closing operation on the plug member 903, and the operation unit 81C can perform the opening/closing operation on the plug member 913.

  The grip member 821a may include a grip cover. In that case, in order to suppress the rotation radius of the entire lock mechanism 821 during the rotation operation, the outside of the grip cover may be shaved in a front view of the rotation surface. By doing so, it is possible to protect the lock mechanism while preventing interference with other parts.

  In the example of FIG. 17, the arm member 820 is moved forward and backward relative to the unit body 81B′, but a mechanism for fixing the arm member 820 to the unit body 81B′ is also used as shown in the example of FIG. Can be adopted. In the example of FIG. 24, the unit main body 81B' is horizontally moved in the front-rear direction by a mechanism using the motor 823 as a drive source. As a result, the arm member 820 also moves in the front-back direction, so that the container body 90 can be moved between the extraction position and the bean charging position.

<5. Operation 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. FIG. 20 shows an example of control relating to one coffee beverage manufacturing operation. The state of the beverage production device 1 before the production instruction is called a standby state. The state of each mechanism in the standby state is as follows.

  The extraction device 3 is in the state shown in FIG. The extraction container 9 is in an upright posture and is located at the extraction position. The lock mechanism 821 is in the 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 the raised position and is attached to the convex portion 901c. The plug members 903 and 913 are in the closed state. The switching valve 10a connects the communication portion 810a of the operation unit 81C to the waste tank T. The standby state is not limited to the state shown in FIG. 10, and for example, the extraction container 9 is in the upright posture and located at the extraction position, the lock mechanism 821 is in the open state, and the lid unit 91 is in the opening of the container body 90. 90a may be opened.

  In the standby state, if there is an instruction to manufacture a coffee beverage, the process of FIG. 20 is executed. In S1, preheat treatment is performed. This process is a process of pouring hot water into the container body 90 to heat the container body 90 in advance. First, the plug members 903 and 913 are opened. As a result, the pipe L3, the extraction container 9, and the waste tank T are in communication with each other.

  The solenoid valve 72i is opened for a predetermined time (for example, 1500 ms) and then closed. As a result, hot water is poured into the extraction container 9 from the water tank 72. Subsequently, the electromagnetic valve 73b is opened for a predetermined time (for example, 500 ms) and then closed. As a result, the air in the extraction container 9 is pressurized, and the discharge of hot water to the waste tank T is promoted. By the above process, the inside of the extraction container 9 and the pipe L2 are preheated, and cooling of the hot water can be reduced in the subsequent production of the coffee beverage.

  When hot water is poured into the extraction container 9 in this preheat treatment, the hot water passes through the filter 910. Even if the residue of the ground beans used in the previous production of the coffee beverage or the oil generated by the extraction of the coffee liquid adheres to the filter 910, this is washed out and discharged.

  In step S2, grind processing is performed. Here, the roasted coffee beans are crushed and the ground beans are put into the container body 90. First, the lock mechanism 821 is opened and the holding member 801 is raised to the raised position. The lid 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 descends to the descending position. The container body 90 is moved to the bean charging position. Then, the storage device 4 and the crushing device 5 are operated. As a result, one cup of roasted coffee beans is supplied from the storage device 4 to the grinder 5A. The roasted coffee beans are ground in two stages by the grinders 5A and 5B, and unnecessary substances are separated by the separating device 6. Ground beans are put into the container body 90.

  The container body 90 is returned to the extraction position. The holding member 801 is lowered to the lowered position, and the lid unit 91 is attached to the container body 90. The lock mechanism 821 is closed and the lid unit 91 is airtightly locked to the container body 90. The holding member 811 rises to the raised position. Of the plug members 903 and 913, the plug member 903 is opened and the plug member 913 is closed.

  In S3, extraction processing is performed. Here, the coffee liquid is extracted from the ground beans in the container body 90. FIG. 21 is a flowchart of the extraction process of S3.

  In S11, since the ground beans in the extraction container 9 are steamed, a smaller amount of hot water than one cup of hot water is poured into the extraction container 9. Here, the electromagnetic valve 72i is opened and closed for a predetermined time (for example, 500 ms). As a result, hot water is poured into the extraction container 9 from the water tank 72. Then, after waiting for a predetermined time (for example, 5000 ms), the process of S11 ends. By this process, ground beans can be steamed. Although the pressure and temperature in the extraction container 9 after this treatment slightly increase, there is no great difference from the pressure before the treatment.

  By steaming the ground beans, carbon dioxide gas contained in the ground beans can be released and the subsequent extraction effect can be enhanced. In order to steam the whole ground beans, it is preferable that the amount of hot water for steaming be evenly applied to the ground beans. Therefore, when pouring hot water into the extraction container 9, the electromagnetic valve 72h may be temporarily opened and the water tank 72 may be decompressed and poured. By doing so, it is possible to reduce the momentum of the steam for hot water and to apply the hot water to the beans as evenly as possible, thereby enhancing the steaming effect. The atmospheric pressure in the extraction container 9 during the steaming may be lower than the atmospheric pressure during the subsequent immersion-type extraction (S14) described later (atmosphere in which hot water does not boil). This can accelerate the release of carbon dioxide gas. When the ground beans are brought into contact with a liquid (for example, hot water), for example, when carbon dioxide gas is released from the ground beans during steaming, dipping, etc., the release valve 73c is opened once after steaming and the atmosphere is released. Alternatively, the ground beans may be soaked in the liquid (for example, hot water) without being released by also applying the pressure of the carbon dioxide gas. For example, in the case of the beverage manufacturing device 1, the ground beans are steamed at 2 atm (3 atm in absolute pressure) or 0 atm (1 atm in absolute pressure), and then at 2 atm (3 atm in absolute pressure) A liquid (for example, hot water) is poured into the extraction container 9, immersed at 4 atm (5 atm in absolute pressure), bumped at atmospheric pressure (0 atm (1 atm in absolute pressure)), and the extraction container 9 is rotated. After that, dipping and delivery to the outside of the extraction container 9 are performed while applying 0.7 atm (1.7 atm in absolute pressure) to the extraction container 9, but the pressure of carbon dioxide gas released from the ground beans is also The ground beans may be steamed, soaked, or delivered, or steaming may be performed after releasing carbon dioxide into the atmosphere before execution, or releasing carbon dioxide into the atmosphere before soaking at 4 atmospheric pressure. Or release carbon dioxide into the atmosphere before dipping at 2 atmospheres before the 4 atmospheres, or release carbon dioxide into the atmosphere before dipping or delivering 0.7 atmospheres after the 4 atmospheres. May be. Steaming is also performed with the pressure of carbon dioxide added, immersion with 4 atm is also performed with the pressure of carbon dioxide (for example, dipping is performed at 4 atm + pressure of carbon dioxide), before 4 atm. Immersion at 2 atm is also done by adding the pressure of carbon dioxide (for example, dipping at 2 atm + pressure of carbon dioxide). Immersion at 4 atm after 0.7 atm is also added by the pressure of carbon dioxide. (For example, dipping may be performed at a pressure of 0.7 atm+carbon dioxide).

  The presence or absence of steaming may be selectable by setting. If steaming is not performed, water injection is performed only once, which has the effect of shortening the time until the completion of coffee beverage production.

  In S12, the remaining amount of hot water is poured into the extraction container 9 so that one cup of hot water is stored in the extraction container 9. Here, the electromagnetic valve 72i is opened and closed for a predetermined time (for example, 7000 ms). As a result, hot water is poured into the extraction container 9 from the water tank 72. In the present embodiment, the amount of hot water is managed by the opening time of the solenoid valve 72i, but the amount of hot water may be managed by measurement with a flow meter or other method.

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

  Subsequently, this state is maintained for a predetermined time (for example, 7,000 ms) to perform the immersion type coffee liquid extraction (S14). Thereby, the extraction of the coffee liquid is performed by the immersion method under high temperature and high pressure. The following effects can be expected in the immersion type extraction under high temperature and high pressure. First, by applying a high pressure, hot water can easily penetrate into the ground beans and the extraction of coffee liquid can be promoted. Second, high temperature accelerates extraction of coffee liquor. Third, the high temperature lowers the viscosity of the oil contained in ground beans and accelerates oil extraction. This makes it possible to produce a coffee drink with a high aroma. It should be noted that although there is a view that an astringent taste is likely to be produced when the coffee liquid is extracted at a high temperature, in the present embodiment, unnecessary substances such as chaff that cause the astringent taste are removed in the separation device 6. Therefore, the astringent taste can be suppressed even when the coffee liquid is extracted at a high temperature.

  The temperature of hot water (high-temperature water) may be higher than 100 degrees Celsius, but higher temperature is more advantageous in extracting coffee liquid. On the other hand, increasing the temperature of the hot water generally increases the cost. Therefore, the temperature of the hot water may be, for example, 105 degrees Celsius or higher, 110 degrees Celsius or higher, or 115 degrees Celsius or higher, and may be 130 degrees Celsius or lower, or 120 degrees Celsius or lower, for example. The pressure may be any pressure that does not boil the hot water.

  In S15, the pressure inside the extraction container 9 is reduced. Here, the atmospheric pressure in the extraction container 9 is switched to the atmospheric pressure at which the hot water boils. Specifically, the plug member 913 is opened, and the electromagnetic valve 73c is opened and closed for a predetermined time (for example, 1000 ms). The inside of the extraction container 9 is opened to the atmosphere. Then, the plug member 913 is closed again.

  The inside of the extraction container 9 is rapidly depressurized to a pressure lower than the boiling point pressure, and the hot water in the extraction container 9 boils at a dash. Hot water and ground beans in the extraction container 9 explosively scatter in the extraction container 9. Thereby, the hot water can be boiled uniformly. Further, it is possible to promote the destruction of the cell wall of ground beans and further accelerate the subsequent extraction of coffee liquor. Moreover, since the ground beans and hot water can be stirred by this boiling, extraction of the coffee liquid can be promoted. Thus, in this embodiment, the extraction efficiency of coffee liquid can be improved. By opening the release valve (73c), the atmospheric pressure in the extraction container 9 is rapidly reduced. The rapid depressurization may be, for example, depressurizing at a rate at which one of a bumping state and a state close to bumping occurs, and specifically, the atmospheric pressure in the extraction container 9 is a vapor pressure (saturated steam pressure, equilibrium). It may be the vapor pressure, etc.) and decompress at a rate such that it falls to a pressure lower than that, or suddenly boil the liquid in the extraction container 9 (for example, hot water or a mixture of hot water and coffee liquid) at a temperature above the boiling point. The pressure may be reduced at various rates. By bumping (for example, a liquid that has not boiled (for example, hot water) suddenly boils at a temperature above the boiling point), the cells of ground beans may be destroyed or the beans and hot water may be stirred. ..

  In S16, the extraction container 9 is inverted 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. Then, 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. FIG. 23 shows the state inside the extraction container 9 before and after the inversion. The left side of the drawing shows the extraction container 9 in an upright posture, and the right side of the drawing shows the extraction container 9 in an inverted posture. The lid unit 91 including the neck portion 90b and the filter 910 is located on the lower side. The reversal from the upright posture to the inverted posture is not limited to rotating the extraction container 9 by 180 degrees by performing an operation involving the rotation of the extraction container 9, and is not limited to a certain angle (for example, 170 degrees) less than 180 degrees. ) Or a certain angle exceeding 180 degrees (for example, 190 degrees). The extraction container 9 may be rotated up to plus or minus 90 degrees. For example, regarding the upright posture and the inverted posture, the upright posture is defined as a portion farthest from a certain portion that constitutes the opening 90a of the extraction container 9 and a portion that does not constitute the opening 90a of the extraction container 9. It is a posture in which the certain portion is located at a higher position than the far portion, and the inverted posture may be a posture in which the certain portion is located at a lower position than the far portion. Is a posture in which the certain part is higher than the distant part and stands still, and an inverted posture is a state in which the certain part is lower than the distant part. It may have a posture. Also, what kind of action should be taken during the posture change from the upright posture to the inverted posture, such as rotating a predetermined number of times (for example, once, plural times, etc.) 360 degrees when rotating from the upright posture to the inverted posture. The position of the extraction container 9 having an upright posture and the position of the extraction container 9 having an inverted posture may be different positions in the front, rear, up, down, left and right, instead of merely rotating.

  In S17, transparent coffee liquid extraction is performed, and the coffee beverage is delivered to the cup C. Here, the switching valve 10a is switched so that the pouring portion 10c communicates with the passage portion 810a of the operation unit 81C. In addition, both the plug members 903 and 913 are opened. Further, the electromagnetic valve 73b is opened for a predetermined time (for example, 10,000 ms) to bring the inside of the extraction container 9 to a predetermined atmospheric pressure (for example, 1.7 atmospheric pressure (gauge pressure: 0.7 atmospheric pressure)). In the extraction container 9, the coffee beverage in which the coffee liquid is dissolved in the hot water passes through the filter 910 and is delivered to the cup C. The filter 910 regulates leakage of ground bean residues. The extraction efficiency of coffee liquid can be improved by using the immersion type extraction in S14 and the permeation type extraction in S17 together. The extraction process is completed as described above. Here, an example in which the pressure by the carbon dioxide gas is not released to the atmosphere before the permeation type coffee liquid extraction is shown, but before the permeation type coffee liquid extraction, the release valve 73c is opened to open the inside of the extraction container 9. It is preferable to release the pressure of the carbon dioxide gas to the atmosphere by releasing the carbon dioxide gas released from the ground beans to the atmosphere.

  Note that, at the time of the permeation type coffee liquid extraction in S17, only the plug member 903 may be opened and once opened to the atmospheric pressure. By doing so, the atmospheric pressure in the extraction container 9 raised by the carbon dioxide gas generated during the immersion extraction can be lowered. After performing this operation, the cup member 913 may be opened and the electromagnetic valve 73b may be opened to extract the coffee liquid.

  The determination of the end of the extraction process may be made based on the pressure change inside the extraction container 9 during the extraction process. For example, when the pressure falls below 1.7 atm to maintain 1.7 atm, pressurization is performed by opening and closing the solenoid valve 73b, and the time interval from pressurization to the next pressurization is half or less from the start of delivery. When it becomes, it may be judged that the transmission is completed and the extraction processing may be ended. Alternatively, the determination may be made by increasing the number of pressurizations per unit time.

  Here, the relationship between the reversing operation in S16 and the transmissive coffee liquid extraction in S17 will be described with reference to FIG. When the extraction container 9 is in the upright posture, ground beans are accumulated from the body portion 90e to the bottom portion 90f. On the other hand, when the extraction container 9 is in the inverted posture, ground beans are accumulated from the shoulder portion 90d to the neck portion 90b. The cross-sectional area SC11 of the body portion 90e is larger than the cross-sectional area SC12 of the neck portion 90b, and the accumulated thickness H2 of ground beans in the inverted posture is thicker than the accumulated thickness H1 in the upright posture. That is, the ground beans are relatively thin and widely deposited when the extraction container 9 is in the upright posture, and relatively thick and narrowly deposited when the extraction container 9 is in the upright posture.

  In the case of the present embodiment, since the extraction container 9 in S14 is performed with the extraction container 9 in the upright posture, the hot water and the ground beans can be brought into contact with each other over a wide range, and the extraction efficiency of the coffee liquid can be improved. However, in this case, the hot water tends to partially contact the ground beans. On the other hand, since the transparent extraction of S17 is performed with the extraction container 9 in the inverted posture, the hot water passes through the accumulated ground beans while contacting more ground beans. The hot water comes into contact with the ground beans evenly, and the extraction efficiency of the coffee liquid can be further improved.

  When reducing the cross-sectional area of the internal space of the extraction container 9 on the side of the opening 90a, the neck portion 90b may be formed so as to have a shape that gradually narrows (continuously inclines) to the opening 90a. As described above, it is preferable that a portion having a constant cross-sectional area of the neck portion 90b is secured in the vertical direction by a constant length. By doing so, the amount of hot water permeated per unit volume of ground beans can be made close to uniform, so that it is possible to improve the efficiency of extraction by the permeation method while preventing overextraction. Further, the cross-sectional shape of the extraction container 9 is not limited to the cylindrical shape, and may be a rectangular tube shape or the like, but the coffee liquid can be more uniformly extracted by forming the extraction container 9 in the cylindrical shape as in the present embodiment.

  In addition, since hot water and ground beans are stirred when the extraction container 9 is inverted, the extraction efficiency of coffee liquid can be further improved. In the case of this embodiment, since the shoulder portion 90d is formed between the body portion 90e and the neck portion 90b, it is possible to smoothly move the ground beans from the body portion 90e to the neck portion 90b at the time of reversing.

  After depressurizing, the operation of shaking the extraction container 9 may be performed for the purpose of stirring the inside of the extraction container 9. Specifically, for example, the operation of tilting and returning the posture of the extraction container 9 within a range of 30 degrees may be repeated a plurality of times. This shaking operation may be performed before or after inversion of the extraction container 9.

  Further, in the present embodiment, the immersion type extraction is performed in S14 before the depressurization, but the immersion type extraction may be performed after the depressurization, and in this case, the process of S14 may be deleted, You may perform the process of S14 and may also perform immersion extraction before and after pressure reduction.

  Further, in the present embodiment, as the depressurizing method of S15, the inside of the extraction container 9 is opened to the atmosphere, but the present invention is not limited to this, and the pressure lower than the pressure inside the extraction container 9 (atmospheric pressure or higher or atmospheric pressure or lower). ), any method such as a method of conducting with the container may be adopted. However, the method of the present embodiment is advantageous in terms of the temperature in the subsequent extraction, the temperature of the coffee beverage to be delivered, the ease of pressure reduction, and the width of pressure reduction. Of course, the opening time of the release valve 73c may be adjusted so that the pressure after depressurization becomes a certain pressure higher than atmospheric pressure (for example, 1.1 atmospheric pressure). The pressure after depressurization may be set to a certain pressure lower than the atmospheric pressure (for example, 0.9 atmospheric pressure). Of course, the pressure after depressurization may be atmospheric pressure.

  Further, in order to bring the inside of the extraction container 9 into a high temperature and high pressure state, in the present embodiment, a method of injecting high temperature and high pressure hot water into the extraction container is adopted, but the present invention is not limited to this. For example, a method of injecting water or hot water lower than a desired temperature into the extraction container 9 and then applying pressure and heating may be adopted.

  Returning to FIG. 20, after the extraction process of S3, the discharge process of S4 is performed. Here, a process related to cleaning the inside of the extraction container 9 is performed. FIG. 22 is a flowchart thereof.

  In S21, the extraction container 9 is inverted from the inverted posture to the upright posture. Here, first, the plug members 903 and 913 are closed. The holding member 801 is moved to the raised position, and the holding member 811 is moved to the lowered position. Then, the support unit 81B is rotated. The lid unit 91 including the neck portion 90b and the filter 910 is located on the upper side. Then, the holding member 801 is returned to the lowered position, and the holding member 811 is returned to the raised position. The inside of the extraction container 9 can be cleaned without removing the filter 910. Further, it is possible to accelerate the separation of the ground bean residue attached to the filter 910 from the filter 910 due to the vibration at the time of reversing the extraction container 9 or the impact at the time of completion of the reversal, and to fall.

  In S22, the plug member 913 is opened. The solenoid valve 73f is opened and closed for a predetermined time (for example, 2500 ms). As a result, tap water (purified water) is injected into the extraction container 9. The hot water in the water tank 72 can be used for cleaning, but if the hot water is consumed, the continuous production performance of the coffee beverage is deteriorated. Therefore, in this embodiment, tap water (purified water) is used. However, for cleaning, hot water in the water tank 72 or detergent delivered from a detergent tank (not shown) may be used.

  In this embodiment, there is a portion having a constant cross-sectional outer shape near the end portion (neck portion 90b) on the filter 910 side. For this reason, when pouring the cleaning water into the extraction container 9, the water can be made to flow along the wall surface of the extraction container 9 and the cleaning effect can be enhanced.

  Note that the inside of the extraction container 9 may be opened to the atmosphere for a predetermined time (for example, 500 ms) before the water injection in S22 or the inversion in S21. The residual pressure in the extraction container 9 can be released, and the water injection in S22 can be smoothly performed.

  In this way, when the inside of the extraction container 9 is opened to the atmosphere, the inside of the extraction container 9 becomes 0 atm in gauge pressure. Therefore, when water is injected, the plug member 913 may be automatically opened due to water pressure. In this case, the process of opening the plug member 913 is unnecessary. When the plug member 913 is opened by water pressure, the balance between the force for returning the plug member 913 to the closed state and the water pressure makes it easier for water to flow along the inner wall surface of the extraction container 9 and the like. Water is easily supplied to the whole.

  In S23, the plug member 903 is opened. The switching valve 10a connects the communication portion 810a of the operation unit 81C to the waste tank T. As a result, the pipe L3, the extraction container 9, and the waste tank T are in communication with each other. The electromagnetic valve 73b is opened and closed for a predetermined time (for example, 1000 ms). As a result, the inside of the extraction container 9 is pressurized, and the water in the extraction container 9 is discharged to the waste tank T together with the residue of ground beans. After that, the plug members 903 and 913 are closed, and the process ends.

  Since the water used for cleaning is discharged from the communication hole 901a different from the communication hole 911a for discharging coffee beverage, it is possible to prevent the communication hole 911a from becoming dirty.

  The communication hole 901a may be larger than the communication hole 911a, which facilitates discharging of residues and the like. Further, the pressurization inside the extraction container 9 may be started during the water injection in S22. This makes it possible to more effectively discharge water and residues in S23. The pressure inside the extraction container 9 can be more vigorously discharged by pressurizing the extraction container 9 at once to about 5 atm (4 atm in gauge pressure). It is possible to supply water to every corner of the inside 9 and improve the cleaning ability of the entire inside.

  Further, the plug members 903 and 913 may be left in the open state after the process of S23 is not closed.

  As described above, one coffee beverage manufacturing process is completed. After that, the same processing is repeated for each manufacturing instruction. The time required to manufacture one coffee beverage is, for example, about 60 to 90 seconds.
