<First embodiment>
<1. Overview of beverage production equipment>
FIG. 1 is a schematic diagram of the beverage production apparatus 1, and FIG. 2 is a block diagram of a control device 11 of the beverage production 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 a cup of coffee beverage for 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 apparatus 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, for example. 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 a program stored in the storage unit 11b, and controls the actuator group 14 based on an instruction from the operation unit 12 or a detection result of the sensor group 13. The operation unit 12 is a unit that receives an instruction input from a user, and is, for example, a touch panel or a mechanical switch. The user can instruct the production of the coffee beverage via the operation unit 12. The sensor group 13 includes various sensors (for example, a hot water temperature sensor, a mechanism operation position detection sensor, and a pressure sensor) provided in the beverage production apparatus 1. The actuator group 14 is various actuators (for example, a motor, a solenoid valve, a heater, etc.) provided in the beverage production 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 sent to the cup C as a coffee drink through the switching unit 10.

<2. Fluid supply unit and switching unit>
The configuration of the fluid supply unit 7 and the switching unit 10 will be described with reference to FIG. 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 document, when the atmospheric pressure is exemplified by a numeral, it means an absolute pressure unless otherwise specified, and the gauge pressure is an atmospheric pressure where the atmospheric pressure is 0 atm. The atmospheric pressure refers to the atmospheric pressure around the extraction container 9 or the pressure of the beverage production apparatus. For example, when the beverage production apparatus is installed at a point of 0 m above sea level, the international civil aviation organization (= “International Civil Aviation Organization”). Aviation Organization ”[[Omitted] ICAO]) is the standard atmospheric pressure (101.25 hPa) at 0 m above sea level of the international standard atmosphere (=“ 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 pressurizing 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 a reserve tank (accumulator) 71 via a check valve 71a. The pressure in 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 (in this embodiment, 7 atm (gauge pressure is 6 atm)). The reserve tank 71 is provided with a drain 71c for drainage, so that water generated by the compression of air can be drained.

  Hot water (water) constituting the coffee beverage 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. For example, the heater 72a is turned on when the temperature of hot water is 118 degrees Celsius, and is turned off when the temperature is 120 degrees Celsius.

  The water tank 72 is also provided with a water level sensor 72c. The water level sensor 72 c detects the hot water level in the water tank 72. When the water level sensor 72c detects that the water level has fallen below the predetermined water level, water is supplied to the water tank 72. In the case of this embodiment, tap water is supplied through a water purifier (not shown). An electromagnetic valve 72d is provided in the middle of the pipe L2 from the water purifier. When a water level drop is detected by the water level sensor 72c, the electromagnetic valve 72d is opened and water is supplied. The valve 72d is closed and the water supply is shut off. Thus, the hot water in the water tank 72 is maintained at a constant water level. In addition, you may perform the water supply to the water tank 72 whenever the hot water used for manufacture of one coffee drink is discharged | emitted.

  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 air pressure in the reserve tank 71 is supplied to the water tank 72 via the pressure regulating valve 72e and the electromagnetic 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 the present embodiment, the pressure is reduced to 3 atm (2 atm as gauge pressure). The electromagnetic valve 72f switches between supplying and shutting off the air pressure regulated by the pressure regulating valve 72e to the water tank 72. The electromagnetic valve 72f is controlled to be opened and closed so that the atmospheric pressure in the water tank 72 is maintained at 3 atm, except when the tap water is supplied to the water tank 72. When supplying tap water to the water tank 72, the solenoid valve 72h causes the water pressure in the water tank 72 to be lower than the water pressure of the tap water so that the tap water is smoothly replenished by the water pressure of the tap water. The pressure is reduced to (for example, less than 2.5 atmospheres). The electromagnetic valve 72h switches whether or not the inside of the water tank 72 is released to the atmosphere, and releases the inside of the water tank 72 to the atmosphere when the pressure is reduced. The electromagnetic valve 72h also releases the water tank 72 to the atmosphere when the atmospheric pressure in the water tank 72 exceeds 3 atm, except when supplying tap water to the water tank 72, and sets the water tank 72 to 3 atm. maintain.

  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. Hot water is supplied to the extraction container 9 by opening the electromagnetic valve 72i, and supply of hot water is shut off by closing. The amount of hot water supplied to the extraction container 9 can be managed by the opening time of the electromagnetic valve 72i. However, the supply amount may be measured to control the opening / closing of the electromagnetic valve 72i. The pipe L3 is provided with a temperature sensor 73e for measuring the temperature of hot water, and the temperature of the hot water supplied to the extraction container 9 is monitored.

  The air pressure in 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 as gauge pressure). The electromagnetic valve 73b switches between supply and shutoff of the atmospheric pressure regulated by the pressure regulating valve 73a to the extraction container 9. The atmospheric pressure in the extraction container 9 is detected by a pressure sensor 73d. When the inside of the extraction container 9 is pressurized, the electromagnetic valve 73b is opened based on the detection result of the pressure sensor 73d, and the inside of the extraction container 9 has a predetermined atmospheric pressure (in this embodiment, 5 atmospheres at maximum (4 atmospheres as a gauge pressure). )) Under pressure. The atmospheric pressure in the extraction container 9 can be reduced by the electromagnetic valve 73c. The electromagnetic valve 73c switches whether or not the inside of the extraction container 9 is released to the atmosphere, and when the pressure is abnormal (for example, when the inside of the extraction container 9 exceeds 5 atm), the inside of the extraction container 9 is released to the atmosphere.

  When one coffee beverage is manufactured, the inside of the extraction container 9 is washed with tap water in the present embodiment. The electromagnetic valve 73 f is opened at the time of 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 unit 10 c 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 part 10c when the coffee beverage in the extraction container 9 is sent out. The coffee drink is poured into the cup C from the pouring part 10c. When discharging waste liquid (tap water) and residue (ground beans) at the time of washing, 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, the switching valve 10a is preferably a ball valve, and the motor 10b switches its flow path by rotating its rotating shaft.

<3. Bean processing device>
The bean processing device 2 will be described with reference to FIG. FIG. 3 is a perspective view of the bean processing device 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 present embodiment, three canisters 40 are provided. When the three canisters 40 are distinguished, they are referred to as canisters 40A, 40B, and 40C. Each of the canisters 40A to 40C may contain different types of roasted coffee beans, and may select the type of roasted coffee beans used for the production of a coffee beverage by an operation input to the operation unit 12. Different types of roasted coffee beans are, for example, roasted coffee beans of different coffee bean varieties. Further, different types of roasted coffee beans are the same variety of coffee beans, but roasted coffee beans having different roasting degrees may be used. The roasted coffee beans of different types may be roasted coffee beans having different varieties and 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, roasted coffee beans of various varieties may have the same roast degree.

  In this embodiment, a plurality of canisters 40 are provided. However, only one canister 40 may be provided. Further, when a plurality of canisters 40 are provided, all or a plurality of canisters 40 may contain the same type of roasted coffee beans.

  Each canister 40 is provided with a conveyor 41 individually. The conveyor 41 is a delivery mechanism (conveyance mechanism) that automatically sends a predetermined amount of roasted coffee beans stored 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 measures 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 conveyor 41 discharges roasted coffee beans to the downstream collecting conveyance path 42. The collective conveyance path 42 is configured by a hollow member, and includes an input port 42a for each conveyor 41 and a common discharge port 42b, and roasts from the common discharge port 42b to the crushing device 5. Coffee beans are supplied.

<3-2. Crusher>
The grinding device 5 will be described with reference to FIGS. 3 and 4. FIG. 4 is a longitudinal sectional view of the pulverizer 5. The pulverizing apparatus 5 includes grinders 5A and 5B and a separating apparatus 6. The grinders 5A and 5B are mechanisms for grinding roasted coffee beans supplied from the storage device 4. The grinders 5A and 5B have different particle 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. Grinders>
The grinder 5A includes a motor 52a and a main body 53a. The motor 52a is a drive source for the grinder 5A. The main body 53a is a unit that accommodates the cutter, and incorporates a rotating shaft 54a. 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 provided with a rotary blade 58a as a cutter, and a fixed blade 57a as a cutter is provided around the rotary blade 58a. The inside of the main body 53a communicates with the insertion port 50a and the discharge port 51a. The roasted coffee beans supplied from the collective conveyance path 42 enter the main body 53a laterally from the insertion port 50a formed on the side of the main body 53a, and are sandwiched between the rotary blade 58a and the fixed blade 57a. And then crushed. A suppression plate 56a is provided above the rotary blade 58a of the rotary shaft 54a, and the suppression plate 56a suppresses the roasted coffee beans from escaping upward. In the grinder 5A, roasted coffee beans are pulverized to about 1/4, for example. The crushed ground beans are discharged to the separation device 6 from the discharge port 51a.

  Note that the roasted coffee beans supplied to the insertion port 50a may be supplied to such a height as to hit the side instead of from above the rotary blade 58a. In that case, since the roasted coffee beans are prevented from escaping upward by the rotary blade 58a, the suppression plate 56a may not be provided.

  The grinder 5A may change the size of the roasted coffee beans that are discharged after being pulverized by changing the rotational speed of the rotary blade 58a. Moreover, you may change by adjusting the distance between the rotary blade 58a and the fixed blade 57a manually.

  Separating device 6 is a mechanism for separating unwanted matter from ground beans. The separation device 6 is disposed 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 roughly ground by the grinder 5A, and the separation device 6 separates the unwanted matter from the coarsely ground beans. The coarsely ground beans from which the unnecessary items have been separated are finely ground by the grinder 5B. The unnecessary material to be separated by the separation device 6 is typically chaff or fine powder. These can reduce the taste of the coffee beverage. The separation device 6 is a mechanism for separating unnecessary substances by air suction, and 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 for the grinder 5B. The main body 53b is a unit that accommodates the cutter, and incorporates a rotating shaft 54b. The rotation shaft 54b is provided with a pulley 55b, and the driving force of the motor 52b is transmitted to the rotation shaft 54b via the belt 59b and the pulley 55b.

  The rotary shaft 54b is also provided with a rotary blade 58b, and a fixed blade 57b is provided above the rotary blade 58b. The inside of the main body 53b communicates with the insertion port 50b and the discharge port 51b. The ground beans falling from the separation device 6 enter the main body 53b from the insertion port 50b, and are further pulverized so as to be sandwiched between the rotary blade 58b and the fixed blade 57b. The ground beans pulverized 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 grind of roasted coffee beans may be a single grinder (one-stage grind). However, as in this embodiment, by using two-stage grinding by the two grinders 5A and 5B, it becomes easy to make the grains of ground beans uniform, and the degree of coffee liquid extraction can be made constant. When beans are crushed, heat may be generated due to friction between the cutter and the beans. By using two-stage pulverization, heat generation due to friction during pulverization can be suppressed, and deterioration of ground beans (for example, a decrease in flavor) can also be prevented.

  Further, by passing through the steps of coarse grinding → separation of unnecessary materials → fine grinding, the mass difference between the unnecessary products and ground beans (necessary portion) can be increased when separating unnecessary products such as chaff. This can increase the separation efficiency of unnecessary items and can prevent ground beans (necessary parts) from being separated as unnecessary items. In addition, since an unnecessary material separation process using air suction is interposed between coarse grinding and fine grinding, heat generation of the ground beans can be suppressed by air cooling. Thereby, deterioration (for example, a flavor falls) of ground beans can also be prevented.

<3-2-2. Separation device>
Next, the separation device 6 will be described with reference to FIGS. FIG. 5 is a partially broken 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 (horizontal direction in the case of this embodiment) intersecting with the passing direction of ground beans (up and down direction in the case of this embodiment), and air in the separation chamber SC. It is a unit that sucks. By sucking the air in the separation chamber SC, lightweight objects such as chaff and fine powder are sucked. Thereby, an unnecessary thing can be isolate | separated from 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 part 62 has a bottomed cylindrical shape with the upper part open, and forms a space for accumulating unnecessary materials. The upper portion 61 constitutes a lid portion that is attached to the opening of the lower portion 62. The upper part 61 includes a cylindrical outer peripheral wall 61a and an exhaust pipe 61b formed coaxially therewith. The blower unit 60A is fixed to the upper portion 61 above the exhaust tube 61b so as to suck air in the exhaust tube 61b. The upper part 61 also includes a cylindrical connecting part 61c extending in the radial direction. The connecting portion 61c is connected to the forming unit 6B and allows the separation chamber SC and the recovery container 60B to communicate with each other. The connecting portion 61c opens to the side of the exhaust cylinder 61b.

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

  A plurality of fins 61d are integrally formed on the peripheral surface of the exhaust cylinder 61b. The plurality of fins 61d are arranged in the circumferential direction of the exhaust cylinder 61b. The individual fins 61d are inclined obliquely with respect to the axial direction of the exhaust cylinder 61b. By providing such a fin 61, the turning around the exhaust pipe 61b of the air containing the unnecessary object D is promoted. Further, the separation of the unwanted material D is promoted by the fins 61. As a result, the length of the suction unit 6A in the vertical direction can be suppressed, which contributes to downsizing of the apparatus.

  Moreover, in this embodiment, while forming unit 6B is arrange | positioned in the fall path | route of ground beans by grinder 5A and 5B, the suction unit 6A of the centrifugal separation system is arrange | positioned to the side of the fall path | route. Although the centrifugal separation mechanism tends to be long in the vertical direction, the suction unit 6A is arranged side by side with respect to the grinder 5A and the grinder 5B by disposing the suction unit 6A from the dropping path to the side. Can do. This contributes to reducing the vertical length of the device. In particular, when the two-stage grinding is performed by the two grinders 5A and 5B as in the present embodiment, the length in the vertical direction of the device tends to be long, and thus the arrangement of the suction unit 6A is small in size of the device. It is effective for conversion.

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

  In the case of this embodiment, the formation unit 6B is formed by joining two members that are divided in the vertical direction. The forming unit 6B includes a pipe part 63 and a separation chamber forming part 64, and has a spoon shape in plan view. The pipe portion 63 is a cylindrical body that forms a communication path 63a with the suction unit 6A, and extends in the lateral direction (a direction intersecting a center line CL described later). The separation chamber forming portion 64 is an annular hollow body that is connected to the pipe portion 63 and forms the separation chamber SC and has a center opened in the vertical direction.

  In the present embodiment, when separating the unnecessary items from the ground beans, a method of sucking the unnecessary items by applying a lateral wind pressure to the ground beans falling from the grinder 5A is adopted. This is advantageous in that the length in the vertical direction can be shortened as compared with the centrifugal separation method.

  The separation chamber forming portion 64 includes a cylindrical portion 65 that extends in the vertical direction. The cylindrical portion 65 projects into the separation chamber SC from the central portion in the vertical direction to the lower portion. The cylindrical portion 65 has an opening 65a at one upper end, and the opening 65a forms a ground bean inlet 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. Thereby, the ground beans falling from the discharge port 51a are introduced into the separation chamber forming part 64 without leakage. The cylindrical portion 65 has an opening 65b at the other lower end. 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 present embodiment, the cylindrical portion 65 has a cylindrical shape, and the opening 65a and the opening 65b have concentric circular shapes located on the center line CL. Thereby, the ground beans falling from the discharge port 51 a can easily pass through the cylindrical portion 65. The cylindrical 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 cylindrical portion 65 has a mortar shape, the falling ground beans easily collide with the inner wall. The ground beans falling from the grinder 5A may fall as a lump with the grains closely contacting each other. If the ground beans are in a lump state, the separation efficiency of unnecessary materials may be reduced. In the case of this embodiment, the ground beans which became the lump collide with the inner wall of the cylindrical part 65, so that the lump can be broken and unnecessary items can be easily separated.

  The inner wall of the cylindrical portion 65 is not limited to a mortar shape in that the lump of ground beans is broken. If there is a portion having a smaller cross-sectional area in the inner space than the opening 65a at an intermediate portion of the cylindrical portion 65, and if there is an inner wall that is inclined (not horizontal) with respect to the center line CL, it will collide with the lump. While promoting, the ground beans can be dropped smoothly. The cylindrical portion 65 does not need to protrude into the separation chamber SC, and may have only a portion protruding upward from the outer surface of the separation chamber forming portion 64. However, the wind speed around the cylindrical portion 65 can be improved by projecting the cylindrical portion 65 into the separation chamber SC. For this reason, in the area | region R1 comparatively far from the pipe part 63, the separation effect of the unwanted material by a wind pressure can be heightened.

  The separation chamber forming section 64 has a discharge port 66 that communicates with the separation chamber SC through which the ground beans after separating unnecessary substances are discharged. In the case of this embodiment, the discharge port 66 is located below the opening 65b, and the ground beans that have passed through the cylindrical portion 64 pass through the separation chamber SC and freely fall from the discharge port 66. In the present embodiment, the discharge port 66 is a circular opening located on the center line CL, and is an opening concentric with the opening 65a and the opening 65b. For this reason, it becomes easy for the ground beans to pass through the separation chamber forming portion 64 due to free fall, and the ground beans can be prevented from accumulating in the separation chamber forming portion 64.

  As shown in FIG. 8, in 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 the present embodiment, the opening 65b and the discharge port 66 overlap each other when viewed in the vertical direction. Accordingly, when the opening 65 b is projected in the vertical direction with respect to the discharge port 66, the opening 65 b is accommodated inside the discharge port 66. In other words, the opening 65b is accommodated in a 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 are overlapped, or a configuration in which at least one is not circular but overlaps may be employed.

  The ratio of the cross-sectional area SC1 to the cross-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. For this reason, the ground beans that freely fall from the opening 65 b are easily discharged from the discharge port 66. Moreover, it can prevent falling ground beans colliding with the edge of the discharge port 66 and jumping to the pipe part 63 side, and it can also suppress that necessary ground beans are attracted | sucked by 6 A of suction units. It has been exemplified that the opening area of the one end opening (for example, 65a) is smaller than the opening area of the discharging opening (for example, 66), but the opening area of the discharging opening (for example, 66) and the opening of the one end opening (for example, 65a) The area may be the same, or the opening area of the one end opening (for example, 65a) may be larger than the opening area of the discharge port (for example, 66). It has been exemplified that the opening area of the other end opening (for example, 65b) is smaller than the opening area of the discharging port (for example, 66), but the opening area of the discharging port (for example, 66) and the other end opening (for example, 65b) The opening area of the other end opening (for example, 65b) may be larger than the opening area of the discharge port (for example, 66). It is exemplified that the air is sucked from the discharge port 66 and the input port (for example, 65a, 65a ′) by the suction unit (for example, 6A), but is more than the amount of air sucked from the input port (for example, 65a, 65a ′). The amount of air sucked from the discharge port 66 may be increased. This is realized by the fact that the other end opening (for example, 65b) protrudes into the separation chamber and that the cross-sectional area of the discharge port 66 is larger than the opening area of the one end opening (for example, 65a). Alternatively, it may be realized by the size of the cross-sectional area of the discharge port 66 being larger than the size of the opening area of the other end opening (for example, 65b), or the separation chamber from the one end opening (for example, 65a). This may be realized by the distance from the discharge port 66 to the separation chamber being shorter than the distance from the exhaust port 66 to the exhaust tube 61b than the distance from the one end opening (for example, 65a) to the exhaust tube 61b. It may be realized by the short distance, or may be realized by the distance from the discharge port 66 to the blower unit 60A being shorter than the distance from the one end opening (for example, 65a) to the blower unit 60A. Any one of the inner walls of the forming unit 6B and the members (63 to 65) constituting the separation chamber SC, the cylindrical portion 65, and the other end opening (for example, 65b), the grinder (at least one of 5A and 5B) ) Directly or indirectly through another member, and vibrations caused by the rotation of the grinder may be transmitted to vibrate. For example, in the case of the beverage production apparatus 1 in the embodiment, since they are in direct or indirect contact, during the operation of the grinder, the members (63 to 65) of the forming unit 6B and the separation chamber SC are configured. Any one of the inner wall portions, the cylindrical portion 65 and the other end opening portion (for example, 65b) vibrate, and turbulent air generated in the separation chamber SC due to the vibration causes the other end opening portion (for example, 65b) to enter the separation chamber SC. A brake is applied to a light unnecessary object that enters, and the unnecessary object is easily sucked by a suction unit (for example, 6A). In particular, the forming unit 6B is in direct contact with the grinder 5A of the grinder 5A and the grinder 5B as in the beverage production apparatus 1 in the embodiment, but the forming unit 6B is in direct contact with one grinder in this way. Appropriate vibration may be applied to the surface to make it easier to suck light unnecessary objects.

  In the case of this embodiment, the air sucked by the suction unit 6 </ b> A is mainly sucked from the discharge port 66. For this reason, a clearance is provided between the discharge port 66 and the input port 50b of the grinder 5B, and air suction is promoted. An arrow d4 schematically shows the direction of the airflow sucked by the suction unit 6A. By sucking air from the discharge port 66, it becomes difficult for unnecessary items to be discharged from the discharge port 66, and the separation performance between ground beans and unnecessary items can be improved. The air sucked by the suction unit 6A is also sucked from the opening 65a.

  A turbulent flow promoting portion 67 is formed on the peripheral wall that defines the discharge port 66. The turbulent flow promoting portion 67 generates turbulent flow in the air sucked from the discharge port 66 to the separation chamber SC. By forming the turbulent flow promoting portion 67, turbulent flow is likely to occur particularly in the region R2 between the opening 65b and the discharge port 66. In the case of this embodiment, since the wind speed is improved around the cylindrical portion 65, the generation of turbulent flow in the region R2 can be synergistically promoted.

  The ground beans introduced into the introduction port 65a are stirred 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. Due to the turbulent flow, unwanted items such as chaff and fine powder are easily separated from the ground beans. Therefore, even if the separation chamber SC is a small space, it is possible to improve the separation efficiency of unnecessary materials. In particular, this contributes to reducing the vertical length of the separation chamber SC, as in this embodiment. This is advantageous in reducing the size of the apparatus when two-stage grinding is performed with two grinders 5A and 5B.

  In the case of the present embodiment, the turbulent flow promoting 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 protruding direction of the turbulent flow promoting element 67a may be any direction, but a direction within the range from the lower side to the radially inner side is preferable in terms of facilitating the generation of turbulent flow in the separation chamber SC. is there. If the protruding direction is downward as in the present embodiment, it is more preferable that the ground beans that have fallen are not caught.

  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 center line CL direction, and a chamfer 67b is provided on the inner side of the tip. The shape of the turbulent flow promoting element 67a is not limited to the shape of this embodiment, but a shape that complicates the shape of the discharge port 66 three-dimensionally is suitable.

  In the case of the present embodiment, the turbulent flow promoting element 67a is repeatedly formed in the peripheral direction d5 of the discharge port 66. Thereby, air blows into the region R from multiple directions, and the generation of turbulent flow is promoted. The pitch of the adjacent turbulent flow promoting elements 67a may be a different pitch, but is equal in this embodiment. Although twelve turbulent flow promoting elements 67a are formed, the number of turbulent flow promoting elements 67a is arbitrary.

<3-2-3. Other configuration examples>
Another configuration example of the separation chamber forming unit 64 will be described with reference to FIG. The turbulence promoting element 67a may be a notch or a hole in addition to the protrusion. The example of EX1 in 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 a hole can also promote the generation of turbulent flow in the region R2.

  The example of EX2 in FIG. 9 shows an example in which the cylindrical portion 65 is not provided. Also in this case, a configuration in which the cross-sectional area SC2 of the discharge port 66 is larger than the cross-sectional area SC1 'of the input port 65a' is preferable.

  The opening 65b of the cylindrical 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 tube portion 63 side protrudes downward from the lower end on the opposite side. By doing in this way, a ground bean is easily guided to the area | region R1 side, the residence time of the ground bean in the separation chamber SC can be taken long, and the separation effect can be heightened.

The arm member 820 includes a holding member 820a and a pair of shaft members 820b separated from each other on the left and right. 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. Thereby, it becomes easy to visually recognize the inside of the container main body 90 in front view.

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

  The pair of shaft members 820b are rods that extend in the front-rear direction, and are members that support the holding member 820a. In the present embodiment, the number of shaft members 820b is two, but may be one or three or more. The holding member 820a is fixed to the front ends of the pair of shaft members 820b. A pair of shaft members 82b are moved forward and backward by a mechanism described later, whereby the holding member 820a is moved forward and backward, and the container main body 90 can be moved in parallel in the longitudinal direction. As will be described later, the middle unit 8 </ b> B can also perform a rotation operation that reverses the top and bottom of the extraction container 9.

<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. 10 and 11 shows a basic posture in which the lid unit 91 is located on the upper side. In the following description, when the vertical positional relationship is described, it means the vertical positional relationship in the basic posture unless otherwise specified.

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

  Both the neck portion 90b and the trunk portion 90e have a cylindrical shape. In the neck portion 90b, a region having the same cross-sectional area or cross-sectional shape of the internal space extends in the vertical direction. 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 cross-sectional area of the internal space is larger in the body portion 90e than in the neck portion 90b. The ratio of the cross-sectional area of the neck portion 90b to the trunk 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 trunk portion 90e, and has a tapered shape so that the cross-sectional area of the internal space gradually decreases from the trunk portion 90e side toward the neck portion 90b side. ing. However, the neck portion 90a 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 the body portion 90e is larger than the neck portion 90b. Instead, the neck portion 90a may be a part of the trunk portion 90e. That is, the extraction container 9 does not have to have a constricted portion as shown in FIG. 10 or the like, and has a cylindrical shape or a cylindrical shape, and a flange portion such as 90c is provided in the vicinity of the opening 90a or the opening 90a. It may be a different shape.

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

  The upper unit 8A includes an operation unit 81A. The operation unit 81A performs an opening / closing operation (lifting / lowering) of the lid unit 91 with respect to the container body 90 and an 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 support member 800 is fixedly provided so that the relative position with respect to the frame F does not change. A housing portion 800b for housing the holding member 801 is included. The accommodating portion 800b is a cylindrical space that opens downward and has a top portion closed. The support member 800 also includes a communication portion 800a that allows the pipe L3 to communicate with the inside of the housing 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 also includes a communication portion 801a that allows the storage portion 800b and the storage portion 801b to communicate with each other. Hot water, tap water, and atmospheric pressure supplied from the pipe L3 are introduced into the accommodating 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 vertical direction within the housing portion 800b. The holding member 801 is formed with a seal member 801c that seals between the holding member 801 and the accommodating portion 800b, and the airtightness in the accommodating portion 800b is maintained even while the holding member 801 is slid.

  An engaging portion 801d that protrudes radially inward is formed on the inner wall of the accommodating portion 801b. The lid unit 91 is held by the holding member 801 by the engagement of the engaging portion 801d and the ring spring 918 of the lid unit 91. When a certain level or more of force 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 918 is released by elastic deformation of the ring spring 918. Thereby, the lid unit 91 and the holding member 801 are separated.

  The elevating shaft 802 is provided such 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 movable up and down with respect to the support member 800. The support member 800 is provided with a seal member 800c at a hole portion through which the elevating shaft 802 passes, and the airtightness in the housing portion 800b is maintained even while the elevating shaft 802 is slid.

The holding member 801 slides in the vertical direction by raising and lowering the lifting shaft 802, and the mounting and separation of the holding member 801 on the convex portion 911d and the convex portion 901c can be performed. 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 an open state. The holding member 801 that holds the lid unit 91 is in the raised position, and the held lid unit 91 is separated above the container body 90. In FIG. 15, illustration of some components is omitted.

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

  The elevating shaft 802 is a tubular shaft having a through hole in the central axis, and a probe 803 is inserted into the through hole so as to be slidable up and down. The probe 803 penetrates the top of the holding member 801 in the vertical direction, and is provided so as to be movable up and down 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, and the airtightness in the housing portion 801b is maintained even while the ascending probe 803 is slid.

  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, the plug member 903 can be pressed from the closed state to the open state using the pressure of the air supplied to the extraction container 9 or the pressure of water. In this case, the atmospheric pressure and the water pressure may be higher than the urging force of the coil spring 905.

  FIG. 16 shows an opening / closing mode of the plug member 903 (and the plug member 913). The holding member 801 is in the lowered position, and the convex portion 911 d is inserted into the holding member 801. Then, it is understood that the plug member 903 can be displaced to an open state indicated by a broken line by lowering the probe 803 (not shown in FIG. 16). When the top and bottom of the extraction container 9 are inverted, the plug member 913 can be changed from the closed state to the open state. In FIG. 16, illustration of some components is omitted.

  The lower unit 8C includes an operation unit 81C. The operation unit 81 </ b> C has a configuration in which the operation unit 81 </ b> A is inverted up and down, and opens and closes the plug members 903 and 913. The operation unit 81 </ b> C is also configured to be able to open and close the lid unit 91, but in this embodiment, the operation unit 81 </ b> C is not used to open and close the lid unit 91.

  Hereinafter, although it is substantially the same as the description of the operation unit 81A, the operation unit 81C will be described. The operation unit 81 </ b> C 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. An accommodating portion 810b that accommodates the holding member 811 is included. 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 allows the switching valve 10a of the switching unit 10 to communicate with the inside of the accommodating portion 810b. The coffee beverage, tap water, and ground bean residue in the container body 90 are introduced into the switching valve 10a via the communication portion 810a.

  The holding member 811 includes an accommodating 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 bottom portion closed. 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. The coffee beverage, tap water, and ground bean residue in the container body 90 are introduced into the switching valve 10a through the communication portions 810a and 811b. The holding member 811 is a movable member provided so as to be slidable in the vertical direction within the accommodating portion 810b. The holding member 811 is formed with a seal member 811c that seals between the holding member 811 and the accommodating portion 810b, and the airtightness in the accommodating portion 810b is maintained even while the holding member 811 is slid.

  An engaging portion 801d that protrudes radially inward is formed on the inner wall of the accommodating portion 811b. The lid unit 91 is held by the holding member 811 by the engagement of the engaging portion 811d and the ring spring 918 of the lid unit 91. When a certain level or more of force that separates the holding member 811 and the lid unit 91 in the vertical direction acts, the engagement between the engagement portion 811d and the ring spring 918 is released due to elastic deformation of the ring spring 918. Thereby, the lid unit 91 and the holding member 811 are separated.

  The elevating shaft 812 is provided such that its axial direction is the vertical direction. The elevating shaft 812 penetrates the bottom of the support member 800 in the vertical direction, and is provided so as to be movable up and down with respect to the support member 810. The support member 810 is provided with a seal member 810c at a hole portion through which the elevating shaft 812 passes, and the airtightness in the accommodating portion 810b is maintained even while the elevating shaft 812 slides.

  The bottom portion of the holding member 811 is fixed to the lower end portion of the elevating shaft 812. The holding member 811 slides in the vertical direction by raising and lowering the elevating shaft 812, so that the holding member 811 can be attached to and detached from the convex portion 901c and the convex portion 911d. A screw 812a constituting a lead screw mechanism is formed on the outer peripheral surface of the elevating shaft 812. A nut 814b is screwed to the screw 812a. The lower unit 8C includes a motor 814a, and the nut 814b is rotated on the spot (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 central axis, and a probe 813 is inserted into the through hole so as to be slidable up and down. The probe 813 penetrates the bottom of the holding member 811 in the vertical direction, and is provided so as to be movable up and down 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, and the airtightness in the housing portion 811b is maintained even while the probe 813 is slid.

  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. Note that the plug member 913 can be pressed from the closed state to the open state by using the air pressure of the air supplied to the extraction container 9 or the water pressure of water without using the probe 813. In this case, the atmospheric pressure or the water pressure may be higher than the urging 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 a liquid for cleaning the extraction container 9 (for example, purified water, hot water, detergent) is a liquid charging part (plug member) 913 and the plug member 903) are not opened in advance and liquid is press-fitted, but the user's preference, how to show to the user via the transmission part 101, and the degree of liquid momentum are different from usual In order to do so, it may be preferable to close the input part (the plug member 913 or the plug member 903) to be less closed or fully open, and to open the input part with the hydraulic pressure of the liquid to be input. For example, the liquid may enter the extraction container 9 instantaneously or may be poured onto the shower on the inner wall portion of the extraction container 9 or the extraction target (for example, ground beans of roasted coffee).

  FIG. 16 shows an opening / closing mode of the plug member 913 (and the plug member 903). The holding member 811 is in the raised position, and the convex portion 901 c is inserted into the holding member 811. It is understood that the plug 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 top and bottom of the extraction container 9 are inverted, the plug member 903 can be changed from the closed state to the open state.

  A screw 813a constituting a lead screw mechanism is formed on the outer peripheral surface of the probe 813. A nut 815b is screwed to the screw 813a. The lower unit 8C includes a motor 815a, and the nut 815b is provided to rotate on the spot (without moving up and down) by the driving force of the motor 815a. The probe 813 moves up and down by the rotation of the nut 815b.

<4-4. Central unit>
The middle unit 8B will be described with reference to FIGS. 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 main 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 maintains the lid unit 91 in a closed state with respect to the container main body 90. The lock mechanism 821 includes a pair of gripping members 821a that vertically sandwich 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 that sandwiches and fits the flange portion 911c and the flange portion 90c, and is opened and closed in the left-right direction by the driving force of the motor 822. When the pair of gripping members 821a are in the closed state, as indicated by the solid lines in the box of FIG. 17, each gripping member 821a fits into the flange portion 911c and the flange portion 90c so as to be sandwiched between them, and the lid The unit 91 is airtightly locked with respect to the container main body 90. In this locked state, even if the holding member 801 is raised by the elevating shaft 802 to open the lid unit 91, the lid unit 91 does not move (the lock is not released). That is, the force of locking by the lock mechanism 821 is set stronger than the force of opening the lid unit 91 using the holding member 801. Thereby, it can prevent that the cover unit 91 will be in an open state with respect to the container main body 90 at the time of abnormality.

  Further, when the pair of gripping members 821a are in the open state, as indicated by broken lines in the box of FIG. 17, the gripping members 821a are separated from the flange portions 911c and the flange portions 90c, and the lid unit 91 and the container main body 90 are separated. Is unlocked.

  In the example shown in the figure, the C-shaped cross section of the gripping member 821a has a rectangular shape (the upper side and the lower side are parallel), but may have a trapezoidal shape in which the cross-sectional area becomes narrower on the opening end side. Thereby, the collar part 911c and the flange part 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 the holding member 801 is raised from the lowered position to the raised position, the pair of gripping members 821a are in the open state The lid unit 91 is separated from the container body 90. Conversely, when the pair of gripping members 821a are in the open state, the engagement between the engaging portion 801d and the ring spring 918b is released, and only the holding member 801 is raised.

  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. Thereby, the container main body 90 supported by the arm member 820 can be moved between the rear extraction position (state ST1) and the front bean charging position (state ST2). FIG. 18 shows how the container body 90 moves. In FIG. 18, the position of the container main body 90 indicated by a solid line indicates the extraction position, and the position of the container main body 90 indicated by a broken line is the bean charging position. The bean input position is a position where the ground beans are input into the container body 90, and the ground beans ground by the grinder 5B are input 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 main 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 where coffee liquid is extracted. 10 and 13 to 16 show a case where the container main body 90 is in the extraction position. In this way, by changing the position of the container body 90 between the input of ground beans and the extraction of coffee liquid and the supply of water, steam generated during the extraction of the coffee liquid is the grinder 5B serving as the ground bean supply section. Therefore, it is possible to prevent ground beans from adhering to the discharge port 51b due to steam moisture.

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

  Note that the gripping member 821a may include a gripping part cover. In that case, in order to suppress the rotation radius of the entire lock mechanism 821 at the time of the rotation operation, the outer side of the grip portion cover may be sharpened in front view of the rotation surface. By doing so, it is possible to protect the lock mechanism while preventing interference with other components.

  In the example of FIG. 17, the arm member 820 is moved forward and backward relative to the unit main body 81B ′, but a mechanism for fixing the arm member 820 to the unit main body 81B ′ as shown in the example of FIG. It 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-rear direction, so that the container body 90 can be moved between the extraction position and the bean charging position.

<5. Example of operation control>
A control processing example of the beverage production apparatus 1 executed by the processing unit 11a will be described with reference to FIGS. FIG. 20 shows a control example related to one coffee beverage manufacturing operation. The state of the beverage production apparatus 1 before the production instruction is referred to as a standby state. The state of each mechanism in the standby state is as follows.

  The extraction device 3 is in the state 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 a closed state, and the lid unit 91 closes the opening 90a of the container body 90. The holding member 801 is in the lowered position and is attached to the convex portion 911d. The holding member 811 is in the raised position and is attached to the convex portion 901c. The plug members 903 and 913 are in a closed state. The switching valve 10a makes the communication part 810a of the operation unit 8C communicate with the waste tank T. The standby state is not limited to the state shown in FIG. 10. For example, the extraction container 9 is in an upright posture and is located at the extraction position, the lock mechanism 821 is in the open state, and the lid unit 91 is open to the container body 90. 90a may be opened.

  In the standby state, when there is a coffee drink production instruction, 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 and heating the container body 90 in advance. First, the plug members 903 and 913 are opened. Thereby, the piping L3, the extraction container 9, and the waste tank T are brought into a communication state.

  The electromagnetic valve 72i is opened after a predetermined time (for example, 1500 ms) and then closed. Thereby, hot water is poured into the extraction container 9 from the water tank 72. Subsequently, the electromagnetic valve 73 is opened for a predetermined time (for example, 500 ms) and then closed. Thereby, the air in the extraction container 9 is pressurized, and the discharge of hot water to the waste tank T is promoted. By the above processing, the inside of the extraction container 9 and the pipe L2 are preheated, and it is possible to reduce the cooling of hot water in the subsequent production of the coffee beverage.

  In addition, when hot water is poured into the extraction container 9 in this pre-heat treatment, the hot water passes through the filter 910. Even if the ground bean residue used in the previous coffee beverage production or the oil produced by the extraction of the coffee liquor adheres to the filter 910, it is washed away and discharged.

  In S2, a grinding process is performed. Here, the roasted coffee beans are crushed and the ground beans are put into the container body 90. First, the 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 main body 90. The holding member 811 descends to the lowered position. The container main body 90 is moved to the bean charging position. Subsequently, the storage device 4 and the crushing device 5 are operated. Thereby, one cup of roasted coffee beans is supplied from the storage device 4 to the grinder 5A. The roasted coffee beans are ground in two stages by the grinders 5A and 5B, and the unnecessary product is separated by the separating device 6. The 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 main body 90. The lock mechanism 821 is closed, and the lid unit 91 is hermetically 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 in an open state and the plug member 913 is in a closed state.

  In S3, an extraction process 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 in S3.

  In S <b> 11, in order to steam the ground beans in the extraction container 9, a smaller amount of hot water than the full 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). Thereby, 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 is terminated. By this treatment, the ground beans can be steamed. In addition, although the pressure and temperature in the extraction container 9 after this process rise a little, there is no big difference from before the process.

  By steaming the ground beans, carbon dioxide contained in the ground beans can be released and the subsequent extraction effect can be enhanced. In order to steam the whole ground beans, the amount of the hot water for steaming is preferably applied evenly to the ground beans. Therefore, when pouring hot water into the extraction container 9, the electromagnetic valve 72 h may be temporarily opened to inject the water tank 72 while reducing the pressure. By doing so, it is possible to reduce the momentum of the hot water for steaming and to apply hot water to the beans as evenly as possible, and to enhance the steaming effect. In addition, you may perform the atmospheric pressure in the extraction container 9 at the time of steaming at the atmospheric | air pressure (atmospheric pressure which does not boil hot water) lower than the atmospheric pressure at the time of the subsequent immersion type extraction (S14) mentioned later. Thereby, discharge | release of a carbon dioxide gas can be accelerated | stimulated. When the ground beans are brought into contact with a liquid (for example, hot water), for example, when steamed, immersed, etc., the carbon dioxide gas released from the ground beans is once opened after opening the release valve 73c. Alternatively, the ground beans may be immersed in a liquid (for example, hot water) without applying the pressure of the carbon dioxide gas. For example, in the case of the beverage production apparatus 1, the ground beans are steamed at 2 atmospheres (3 atmospheres in absolute pressure) or 0 atmospheres (1 atmosphere in absolute pressure), and then filled with 2 atmospheres (3 atmospheres in absolute pressure). A liquid (for example, hot water) is poured into the extraction container 9, immersed at 4 atm (5 atm absolute pressure), bumped at atmospheric pressure (0 atm (1 atm absolute pressure)), and the extraction container 9 is rotated. After that, the pressure is applied to the inside of the extraction container 9 while applying 0.7 atm (1.7 atm in absolute pressure), and the outside of the extraction container 9 is sent out. In addition, the ground beans may be steamed, soaked or sent out, steamed after releasing carbon dioxide to the atmosphere before execution, or carbon dioxide released to the atmosphere before immersion at 4 atm. Or carbon dioxide is released into the atmosphere before immersion at 2 atmospheres before the 4 atmospheres, or 0. The carbon dioxide gas may be or discharged into the atmosphere before the immersion and transmission of pressure. Steaming is performed with the pressure of carbon dioxide added, or immersion at 4 atmospheres is performed with the pressure of carbon dioxide added (for example, immersion is performed with pressure of 4 atmospheres + carbon dioxide gas). 2 atmospheric pressure immersion with carbon dioxide pressure added (for example, 2 atmospheric pressure + carbon dioxide pressure immersion), 4 atmospheric pressure 0.7 atmospheric pressure immersion with carbon dioxide gas pressure added (For example, immersion may be performed at a pressure of 0.7 atmospheric pressure + carbon dioxide gas).

  In addition, the presence or absence of steaming may be selectable by setting. In the case where steaming is not performed, water can be poured once, so that the time until the completion of coffee beverage production is shortened.

  In S <b> 12, the remaining amount of hot water is poured into the extraction container 9 so that one cup of hot water is accommodated in the extraction container 9. Here, the electromagnetic valve 72i is opened and closed for a predetermined time (for example, 7000 ms). Thereby, hot water is poured into the extraction container 9 from the water tank 72. In this 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 by other methods.

  By the process of S12, the inside of the extraction container 9 can be brought into a temperature exceeding 100 degrees Celsius (for example, about 110 degrees Celsius) at 1 atmosphere. 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 a pressure at which hot water does not boil (for example, about 4 atmospheres (about 3 atmospheres by gauge pressure)). Thereafter, the plug member 903 is closed.

  Subsequently, this state is maintained for a predetermined time (for example, 7000 ms), and immersion type coffee liquid extraction is performed (S14). Thereby, extraction of the coffee liquid by the immersion type under high temperature and high pressure is performed. The following effects can be expected in the immersion type extraction under high temperature and high pressure. The first is to increase the pressure so that hot water can easily penetrate into the ground beans and promote the extraction of the coffee liquor. Second, the extraction of the coffee liquid is promoted by increasing the temperature. Third, by increasing the temperature, the viscosity of the oil contained in the ground beans is reduced, and oil extraction is promoted. Thereby, a fragrant coffee drink can be manufactured. In addition, although there is an opinion that when the coffee liquid is extracted at a high temperature, it is easy to produce a gummy taste, in this embodiment, unnecessary materials such as chaff that become a source of the gummy taste are removed in the separation device 6. For this reason, even if it is a case where a coffee liquid is extracted at high temperature, an umami | taste can be suppressed.

  The temperature of the hot water (high temperature water) only needs to exceed 100 degrees Celsius, but higher temperature is advantageous in terms of extraction of the coffee liquid. On the other hand, increasing the temperature of hot water generally increases the cost. Therefore, the temperature of the hot water is, for example, 105 degrees Celsius or higher, or 110 degrees Celsius or higher, or 115 degrees Celsius or higher, and may be, for example, 130 degrees Celsius or lower, or 120 degrees Celsius or lower. The atmospheric pressure may be an atmospheric pressure at which hot water does not boil.

  In S15, the inside of the extraction container 9 is depressurized. Here, the atmospheric pressure in the extraction container 9 is switched to an atmospheric pressure at which hot water boils. Specifically, the plug member 913 is opened, and the electromagnetic valve 73c is opened for a predetermined time (for example, 1000 ms) and closed. The inside of the extraction container 9 is released to the atmosphere. Thereafter, 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 all at once. Hot water and ground beans in the extraction container 9 explode in the extraction container 9. Thereby, hot water can be boiled uniformly. Moreover, destruction of the cell wall of ground beans can be promoted, and the subsequent extraction of the coffee liquid can be further promoted. Moreover, since ground beans and hot water can also be stirred by this boiling, extraction of coffee liquid can be accelerated | stimulated. Thus, in this embodiment, the extraction efficiency of the coffee liquid can be improved. By opening the release valve (73C), the pressure in the extraction container 9 is rapidly reduced. The sudden pressure reduction may be, for example, a pressure reduction at a rate at which one of a bumping state or a state close to bumping occurs. Specifically, the atmospheric pressure in the extraction vessel 9 is changed to a vapor pressure (saturated water vapor pressure, equilibrium). Vapor pressure, etc. may be used.) Depressurization at a speed that lowers 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 exceeding the boiling point. The pressure may be reduced at a moderate speed. Due to sudden boiling (for example, a phenomenon that a liquid that has not boiled (for example, hot water) suddenly boils at a temperature exceeding the boiling point), the cells of the ground beans may be destroyed or the ground 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. Thereafter, 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 in the extraction container 9 before and after inversion. The left side of the figure shows the extraction container 9 in an upright posture, and the right side of the figure shows the extraction container 9 in an inverted posture. The lid unit 91 including the neck portion 90b and the filter 910 is positioned on the lower side. The inversion from the upright posture to the inverted posture is not limited to rotating the extraction container 9 by 180 degrees by performing an operation accompanied by the rotation of the extraction container 9, but an angle less than 180 degrees (for example, 170 degrees) ) Or a certain angle exceeding 180 degrees (for example, 190 degrees). The extraction container 9 may be rotated to an angle exceeding 90 degrees. For example, with regard to an upright posture or an inverted posture, an erect posture is a part farthest from a certain part constituting the opening 90a of the extraction container 9 and a part not constituting the opening 90a of the extraction container 9. The position where the certain part is higher than the far part is an attitude, and the inverted posture may be an attitude where the certain part is located lower than the far part. Is a posture that is stationary in a state where the certain part is located higher than the distant part, and an inverted posture is a state in which the certain part is located in a lower position than the distant part It may be a posture. Also, what action should be taken during the posture change from the erect posture to the inverted posture, such as rotating 360 degrees a predetermined number of times (for example, once, multiple times, etc.) when rotating from the erect posture to the inverted posture The position of the extraction container 9 taking an upright posture and the position of the extraction container 9 taking an inverted posture may be different positions on the front, rear, top, bottom, left and right, instead of simply rotating.

  In S <b> 17, a permeable coffee liquid extraction is performed, and a coffee beverage is delivered to the cup C. Here, the switching valve 10a is switched to allow the pouring portion 10c and the passage portion 810a of the operation unit 81C to communicate with each other. Further, the plug members 903 and 913 are both opened. Further, the electromagnetic valve 73b is opened for a predetermined time (for example, 10,000 ms), and the inside of the extraction container 9 is set to a predetermined atmospheric pressure (for example, 1.7 atmospheric pressure (0.7 atmospheric pressure as a gauge pressure)). In the extraction container 9, the coffee beverage in which the coffee liquid is dissolved in hot water passes through the filter 910 and is sent to the cup C. Filter 910 regulates leakage of ground bean residue. The extraction efficiency of the coffee liquid can be improved by using the immersion type extraction at S14 and the transmission type extraction at S17. This completes the extraction process. Here, an example in which the pressure due to 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 and the inside of the extraction container 9 is opened. 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.

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

  The end of the extraction process may be determined by a change in pressure 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 electromagnetic valve 73b, and the time interval from pressurization to the next pressurization is less than half from the start of delivery. When it becomes, it may be determined that the transmission is completed, and the extraction process may be terminated. Further, the determination may be made by increasing the number of pressurizations per unit time.

  Here, with reference to FIG. 23, the relationship between the reversal operation of S16 and the transmission type coffee liquid extraction of S17 will be described. In the state where the extraction container 9 is in the upright posture, the ground beans are accumulated from the trunk portion 90e to the bottom portion 90f. On the other hand, when the extraction container 9 is in the inverted posture, the ground beans are accumulated from the shoulder portion 90d to the neck portion 90b. The cross-sectional area SC11 of the trunk 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 larger than the accumulated thickness H1 in the upright posture. That is, the ground beans are relatively thin and broadly accumulated when the extraction container 9 is in the upright posture, and are relatively thick and narrowly accumulated in the inverted posture.

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

  The neck portion 90b may be formed so as to be gradually narrowed (continuously inclined) to the opening 90a when the cross-sectional area of the internal space of the extraction container 9 is reduced on the opening 90a side. As described above, it is preferable that a portion where the cross-sectional area of the neck portion 90b is constant is ensured by a certain length in the vertical direction. By doing in this way, since the quantity of hot water permeate | permeated per unit volume of ground bean can be closely approached, the efficiency of extraction by a permeation | transmission type | mold can be improved, preventing overextraction. Moreover, the cross-sectional shape of the extraction container 9 is not limited to the cylindrical shape, but may be a rectangular tube shape or the like, but the coffee liquid can be more uniformly extracted by using the cylindrical shape as in the present embodiment.

  Moreover, since hot water and ground beans are stirred when the extraction container 9 is inverted, the extraction efficiency of the coffee liquid can be further improved. In the case of the present embodiment, the shoulder 90d is formed between the trunk portion 90e and the neck portion 90b, so that the ground beans can be smoothly moved from the trunk portion 90 to the neck portion 90b during reversal.

  In addition, you may perform the operation | movement which shakes the extraction container 9 for the purpose of stirring in the extraction container 9 after pressure reduction. 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 the inversion of the extraction container 9 or after the inversion.

  Moreover, in this embodiment, although immersion type extraction is performed in S14 before pressure reduction, you may make it perform immersion type extraction after pressure reduction, In this case, the process of S14 may be deleted, The process of S14 may also be performed to perform immersion extraction before and after decompression.

  In the present embodiment, the inside of the extraction container 9 is released to the atmosphere as the depressurization method of S15. However, the present invention is not limited to this. Any method may be adopted, such as a method of conducting with a container of). However, the system of this embodiment is advantageous in terms of the temperature in subsequent extraction, the temperature of the coffee beverage to be delivered, the ease of decompression, and the decompression width. Of course, the release time of the release valve 73c may be adjusted so that the pressure after depressurization becomes a certain pressure higher than the atmospheric pressure (for example, 1.1 atm). You may make it the pressure after pressure reduction become a certain pressure (for example, 0.9 atmosphere etc.) lower than atmospheric pressure. Of course, the pressure after depressurization may be atmospheric pressure.

  Moreover, in order to make the inside of the extraction container 9 into a high temperature / high pressure state, in this embodiment, the system which inject | pours high temperature / high pressure hot water into an extraction container is employ | adopted, but it is not restricted to this. For example, a method of applying pressure and heating after injecting water or hot water lower than a desired temperature into the extraction container 9 may be adopted.

  Returning to FIG. 20, after the extraction process of S3, the discharge process of S4 is performed. Here, processing relating to cleaning 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. Thereafter, 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 promote that the ground bean residue adhering to the filter 910 is separated from the filter 910 and dropped by the vibration at the time of reversal of the extraction container 9 or the impact at the completion of the reversal.

  In S22, the plug member 913 is opened. The electromagnetic valve 73f is opened and closed for a predetermined time (for example, 2500 ms). Thereby, 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 the continuous production performance of the coffee beverage is reduced when the hot water is consumed. For this reason, in this embodiment, tap water (purified water) is used. However, cleaning may be performed using hot water in the water tank 72 or detergent sent from a detergent tank (not shown).

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

  In addition, you may open the inside of the extraction container 9 to air | atmosphere only for predetermined time (for example, 500 ms etc.) before S22 water injection or inversion of S21. The residual pressure in the extraction container 9 can be released, and water injection in S22 can be performed smoothly.

  Thus, when the inside of the extraction container 9 is released to the atmosphere, the inside of the extraction container 9 becomes 0 atm as a gauge pressure. Therefore, when pouring water, the plug member 913 may be automatically opened by water pressure. In this case, the process of opening the plug member 913 is not necessary. When the plug member 913 is opened by water pressure, the balance between the force with which the plug member 913 returns 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. It becomes easy to supply water to the whole.

  In S23, the plug member 903 is opened. The switching valve 10a makes the communication part 810a of the operation unit 8C communicate with the waste tank T. Thereby, the piping L3, the extraction container 9, and the waste tank T are brought into a communication state. The electromagnetic valve 73b is opened and closed for a predetermined time (for example, 1000 ms). Thereby, the inside of the extraction container 9 is pressurized, and the water in the extraction container 9 is discharged to the disposal tank T together with the residue of ground beans. Thereafter, the plug members 903 and 913 are closed, and the process ends.

  Since the water used for cleaning is sent out from the communication hole 901a different from the communication hole 911a for sending out the coffee beverage, the communication hole 911a can be prevented from becoming dirty.

  Note that the communication hole 901a may be larger than the communication hole 911a, which facilitates discharge of residues and the like. Moreover, you may start pressurization in the extraction container 9 in the middle of the water injection of S22. Thereby, it becomes possible to discharge water and residue in S23 more effectively. As for the pressurization in the extraction container 9, for example, the residue can be discharged more rapidly by pressurizing at a pressure of about 5 atm (4 atm gauge pressure), and the water rises in the extraction container 9, and the extraction container 9 Water can be supplied to every corner of 9 to improve the cleaning ability of the entire interior.

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

  Thus, one coffee beverage manufacturing process is completed. Thereafter, the same processing is repeated for each manufacturing instruction. The time required for producing one coffee drink is, for example, about 60 to 90 seconds.

<Second embodiment>
Another processing example regarding cleaning of the extraction container 9 will be described.

<Discharge processing>
In the discharge process illustrated in FIG. 22, the water injection in S22 and S23, and the discharge of water and residue are performed only once, but may be performed a plurality of times. Thereby, the inside of the extraction container 9 can be maintained more cleanly. FIG. 25 is a flowchart showing an example of a discharge process instead of the discharge process of FIG.

  The processes in S21 to S23 in FIG. 25 are the same as the processes in S21 to S23 in FIG. After the process of S23, it is determined in S24 whether or not a predetermined number of cleanings have been completed. The specified number of times is, for example, twice. If not completed, the process returns to S22, and the processes of S22 and S23 are executed again. If it has been completed, one discharge process is terminated.

  In repeating the processes of S22 and S23, the amount of water, the degree of pressurization, or the timing may be changed.

  Further, the plug member 903 may be closed when water is injected in S22. In that case, water may be stored in the extraction container 9 and the stopper member 913 may be closed, and the inversion operation of the extraction container 9 may be performed once or a plurality of times. Thereby, the cleaning effect in the extraction container 9 can be improved. In addition, when performing the water injection process of S22 several times like the example of FIG. 25, you may perform such inversion operation | movement of the extraction container 9 in the water injection process after the 2nd time. The first time is because the amount of the residue remaining in the extraction container 9 is large, and the scattering in the container is avoided.

<Recleaning process>
The extraction container 9 may be cleaned at a timing other than after the extraction of the coffee liquid. For example, it can be performed in a standby state. Alternatively, it can be performed when the user gives an instruction from the operation unit 12. Thus, the cleaning process of the extraction container 9 performed at timings other than immediately after coffee liquid extraction is called a re-cleaning process. FIG. 26 is a flowchart illustrating an example of the recleaning process.

  In S31, water injection treatment is performed. This is the same processing as S22. In S32, the water poured in S31 is drained. This is the same processing as S23. Thus, one unit of processing is completed.

  Note that the plug member 903 may be closed during the water injection in S31. In the case of the discharging process of FIGS. 22 and 25, the plug member 903 may not be closed during water injection, and the plug member 903 may be closed during water injection only in the case of the re-cleaning process of FIG. Or in the case of the discharge process of FIG.22 and FIG.25, although the stopper member 903 is made into a closed state in the case of water injection, you may vary the amount of water injection in the case of a discharge process, and the case of a re-cleaning process. Further, the water injection amount may be instructable by the user from the operation unit 12.

  The recleaning process is basically performed when the extraction container 9 is in the upright posture, but may be performed in an inverted posture by inverting the extraction container 9.

  Further, after a certain time has elapsed since the production of the coffee beverage, the re-cleaning process using the hot water in the water tank 72 may be automatically performed. By performing this operation, the oil component of the coffee liquid that has cooled and hardened in the flow path can be washed away.

<Third embodiment>
Another configuration example of the bean processing device 2 and the extraction device 3 will be described. In the following description, the same configurations as those in the first embodiment or configurations having common functions are denoted by the same reference numerals as those in the first embodiment, and the description thereof is omitted, and different configurations or functions are mainly described. To do.

  Similar to the first embodiment, the extraction device 3 is disposed below the bean processing device 2 in the present embodiment, and the basic structure is common. The bean processing device 2 includes a storage device 4 and a crushing device 5. The pulverizer 5 includes a coarse-grain grinder 5A, a fine-grain grinder 5B, and a separation device 6 that separates unwanted materials from the ground beans therebetween.

  The forming unit 6B of the separation device 6 and the grinder 5B are connected by a transport pipe 500 extending obliquely downward from the rear to the front. The ground beans from which unnecessary substances have been removed by the separation device 6 are supplied to the grinder 5B through the transfer pipe 500 (substantially spontaneous fall).

  The grinder 5B is provided with a nozzle-type delivery pipe 501. The ground beans refined by the grinder 5B are discharged through the delivery pipe 501. The delivery pipe 501 is arranged so that the outlet thereof is located just above the opening 90a of the container main body 90 when the container main body 90 is located at the bean charging position. In the embodiment of FIG. 27, the container main body 90 is located at the extraction position, and the outlet of the delivery pipe 501 is located slightly in front of the container main body 90.

  In the case of this embodiment, the container main body 90 in the extraction position is located at a position shifted laterally from directly below the grinder 5B. For this reason, the delivery pipe 501 is curved so that the ground beans are delivered to a position shifted from directly below the grinder 5B.

  The main body 53 is provided with a gear 53b ′ for adjusting the grain size of the ground beans. The gear 53b 'is operated by a particle size adjusting mechanism (not shown).

<Suction unit>
The configuration of the suction unit 6A will be described with reference to FIGS. FIG. 28 is a vertical sectional view of the suction unit 6A. The suction unit 6A of the present embodiment is a centrifugal separation mechanism, similar to the suction unit 6A of the first embodiment. The basic operation is the same. That is, the air in the collection container 60B is exhausted upward by the blower unit 60A. As a result, the air containing the unnecessary material from the forming unit 6B turns around the exhaust tube 61b via the connecting portion 61c, and the unnecessary material D falls into the collection container 60B due to its weight. When the air swirls around the exhaust tube 61b, the swirling of the air and the separation of the unwanted material D are accelerated by the fins 61d.

  In the case of this embodiment, the lower part 62 of the collection container 60B includes an upper curved part 62A and a lower collection part 62B, which are separably engaged. The curved portion 62A is a cylindrical body that extends downward from the upper portion 61 and then bends forward.

  The collection part 62B is a straight bottomed cylindrical body without bending, and is fitted to the lower end of the curved part 62A. For this reason, the collection part 62B is inclined and attached to the lower side from the rear to the front. Unnecessary matter D is collected in a part of the collecting unit 62B (deposited on the bottom). When discarding the unwanted material D, the recovery part 62B is removed from the curved part 62A. At this time, since the collection unit 62B can be pulled out forward and downward, the user can easily remove the collection unit 62B from the front of the apparatus.

  The upper portion 61 of the recovery container 60B preferably extends in the vertical direction for centrifugation. By providing the curved portion 62A, both the centrifugal separation performance and the ease of attaching and detaching the collecting portion 62B can be achieved.

  The lower part 62 of the collection container 60B may have a transmission part whose inside is visible from the outside. Alternatively, the curved portion 62A may be a non-permeable member, and only the collection portion 62B may be a permeable member. In any case, the user can visually confirm the amount of deposits of the unwanted material D.

<Chubu unit>
The configuration of the middle unit 8B, particularly the configuration for moving the container body 90 in the horizontal direction, etc. will be described with reference to FIGS. 29 is a partial perspective view of the horizontal movement mechanism provided in the middle unit 8B, and FIG. 30 is a partial perspective view of the arm member 820.

  Similar to the first embodiment, the arm member 820 includes a holding member 820a and a pair of shaft members 820b spaced from each other in the left-right direction. The pair of shaft members 820b are guided and supported by the unit main body 81B 'so as to be movable back and forth. In the present embodiment, the number of shaft members 820b is two, but may be one or three or more.

  Racks 820c are provided at the rear ends of the pair of shaft members 820b, respectively. The rack 820c meshes with a pinion driven by a motor 823 (FIG. 17), and the arm member 820 moves in the front-rear direction by the rotation of the pinion. The moving range can be limited by the front and rear ends of the rack 820c interfering with other components (for example, the front disc portion of the unit main body 81B '). In this embodiment, the arm member 820 is horizontally moved by the rack-pinion mechanism, but other drive mechanisms such as a ball screw mechanism may be used.

  The holding member 820a is fixed to the front end portions of the pair of shaft members 820b. The holding member 820a is an elastic member such as resin as in the first embodiment, and holds the container body 90 by its elastic force. The container main body 90 is attached to and detached from the holding member 820a by manual operation, and the container main body 90 is attached to the holding member 820a by pressing the container main body 90 backward in the front-rear direction against the holding member 820a. Further, the container body 90 can be separated from the holding member 820a by pulling the container body 90 forward from the holding member 820a in the front-rear direction.

  The holding member 820a forms an annular frame that integrally includes a bottom portion BP, left and right side portions SP, an upper portion UP, and left and right engaging portions EP. By making the holding member 820a an annular frame, it is possible to ensure high strength as a whole while allowing elastic deformation thereof.

  The bottom BP has a C-shape with the front side opened in plan view, and the container main body 90 is mounted on the bottom BP. The left and right side portions SP extend upward from the left and right end portions on the rear side of the bottom portion BP, and are fixed to the front end portions of the pair of shaft members 820b. In a state where the container main body 90 is held, the left and right side portions SP are located on the rear side of the container main body 90. The upper part UP is formed so as to connect the upper ends of the left and right side parts SP. In the case of this embodiment, the upper part UP has a convex arch shape. In a state where the container main body 90 is held, the upper part UP is located on the rear side of the container main body 90, and the arch portion slightly overlaps the shoulder 90d. This prevents the container body 90 from being carelessly displaced upward.

  The left and right engaging portions EP extend upward from the upper ends of the left and right side portions SP and slightly inward. In a state in which the container main body 90 is held, the left and right engaging portions EP are located from the side of the container main body 90 to the front side, and the tip portion presses the neck portion 90b from the front side. Thereby, it is suppressed that the container main body 90 falls out from the holding member 820a to the front side.

  As described above, the holding member 820a of the present embodiment is configured so that the front side of the container body 90 can be easily seen from the front in a state where the container body 90 is held, and the user can easily confirm the operation of the container body 90. . Moreover, when it is set as the structure which the whole or one part of the container main body 90 has a permeation | transmission part, the inside becomes easy to see from a front, and it is easy to visually recognize the extraction condition of coffee liquid.

  A roller RL is provided on the rear side of the unit main body 81B '. The roller RL slides on a circular edge provided in the main body frame when the unit main body 81B 'rotates. Three rollers RL may be provided along the circumference of the unit body 81 </ b> B ′ at every 120 degrees or at every 90 degrees. Regardless of the rotation angle of the unit main body 81B ', at least one of the rollers RL supports its weight by the circular edge of the main body frame. By making the distance from the roller RL to the holding member 820a shorter than the distance from the portion supported behind the unit main body 81B ', it is possible to reduce the vertical deflection.

<Storage device>
<Canister and its detachable structure (first example)>
The storage device 4 will be described with reference to FIG. 27 and FIGS. 31 to 34. In the present embodiment, the canister 40 is configured as a cartridge that is detachable from the holder unit 43. Thereby, for example, the type of roasted coffee beans can be exchanged easily and quickly. 31 is an exploded perspective view of the canister 40, FIG. 32 is a cross-sectional view of the cylindrical portion of the canister 40, FIG. 33 is an operation explanatory view of components of the canister 40, and FIG. 34 is a vertical cross-sectional view of the periphery of the canister 40 in the mounted state. .

  The holder unit 43 includes a plurality of mounting portions 44. One canister 40 is detachably attached to one attachment portion 44. In the case of this embodiment, the holder unit 43 includes three mounting portions 44. Therefore, three canisters 40 can be mounted at the same time. When the three canisters 40 are distinguished, they are referred to as canisters 40A, 40B, and 40C.

  The canister 40 of this embodiment is an elongated hollow bean container that accommodates roasted coffee beans. The canister 40 includes a cylindrical part 401, a lid part 402, a connection part 403, a packing 404, an outlet forming part 405, and an outlet opening / closing part 408.

  The tubular portion 401 has a cylindrical shape with both ends open, and defines a storage space for roasted coffee beans. Both end portions of the tubular portion 401 constitute mouths through which roasted coffee beans can enter and exit. The mouth of the end of the tube 401 on the lid 402 side is a mouth through which roasted coffee beans do not pass when roasted coffee beans move from the canister 40 into the beverage manufacturing apparatus 1 (to the conveyor 41). The mouth through which the roasted coffee beans pass when the lid 402 is opened to refill the roasted coffee beans.

  In the case of this embodiment, the cylinder part 401 is formed of a permeable member. Thereby, the remaining amount of the roasted coffee beans accommodated can be visually recognized from the outside. A scale SC is extended on the peripheral wall of the tubular portion 401 in parallel with the axial direction. The scale SC is formed with a scale that is a measure of the remaining amount of roasted coffee beans. As shown in the cross-sectional view of FIG. 32, the scale SC also functions as a connection portion that connects the end portions of the plate-like material forming the cylindrical portion 401.

  A cylindrical connecting portion 403 is fitted to one end portion of the cylindrical portion 401 via an annular packing 404. The packing 404 seals between the flange portion of the connecting portion 403 and the end edge of the cylindrical portion 401, but may be omitted. A female screw is formed on the inner peripheral surface of the connecting portion 403. The lid portion 402 is formed with a male screw threaded on the female screw, and is detachable from the connection portion 403. Therefore, as shown in FIG. 27, in a state where the canister 40 is mounted on the mounting portion 44, the lid portion 402 can be removed by turning and the roasted coffee beans can be replenished.

  The lid portion 402 has a hemispherical shell shape and closes one end of the cylindrical portion 401. A plurality of concave portions are formed in the circumferential direction on the outer peripheral surface of the lid portion 402 so that the user can easily turn the lid portion 402 with a finger.

  The outlet forming portion 405 is fixed to the other end portion of the cylindrical portion 401 by adhesion or the like. The outlet forming portion 405 is a cup-shaped member opened upward, and an outlet 405a is formed on the peripheral wall thereof. The outlet 405a is a mouth through which roasted coffee beans can enter and exit, and the roasted coffee beans accommodated in the tubular portion 401 can be discharged to the outside from the outlet 405a. That is, the outlet 405a is an opening through which the roasted coffee beans pass when the roasted coffee beans move from the canister 40 into the beverage manufacturing apparatus 1 (to the conveyor 41). It is.

  The outlet forming portion 405 is also formed with a protruding portion 405 b that protrudes outside the peripheral wall of the cylindrical portion 401 through the opening 401 a of the cylindrical portion 401. A mark indicating the mounting direction of the canister 40 with respect to the mounting portion 44 is attached to the protruding portion 405b.

  The outlet forming portion 405 is also formed with a detection piece 405c extending downward from the protrusion 405b, and the detection piece 405c also protrudes outside the peripheral wall of the cylindrical portion 401 through the opening 401a. The detection piece 405 c is used to detect whether or not the canister 40 is attached to the attachment portion 44.

  A coil spring 407 is provided at the bottom of the outlet forming portion 405. A fixing member 406 is assembled to the bottom of the outlet forming portion 405. FIG. 31 shows a state in which the fixing member 406 is assembled to the outlet forming portion 405, but actually, after the outlet opening / closing portion 408 is attached to the outlet forming portion 405, the outlet forming portion 405 and the fixing member 406 Thus, the fixing member 406 is assembled to the outlet forming portion 405 so as to sandwich the outlet opening / closing portion 408.

  The outlet opening / closing part 408 is a cup-shaped member that opens upward to receive the outlet forming part 405, and constitutes a lid mechanism or a lid member that opens and closes the outlet 405a. An opening 408 a is formed in the peripheral wall of the outlet opening / closing part 408. When the opening 408a overlaps the outlet 405a, the outlet 405a is opened, and when the peripheral wall of the outlet opening / closing portion 408 overlaps the outlet 405a, the outlet 405a is closed. That is, the outlet opening / closing part 408 is attached to the outlet forming part 405 so as to be rotatable with respect to the outlet forming part 405 around the central axis of the cylindrical part 401. In the case of this embodiment, the outlet opening / closing part 408 is operated by a mechanism on the mounting part 44 side described later, and opens and closes the outlet 405a.

  A cylindrical portion 408b protruding downward is provided at the bottom of the outlet opening / closing portion 408, and a space 408b 'inside the cylindrical portion 408b forms a recess in which the coil spring 407 is disposed. The fixing member 406 described above is assembled to the outlet forming portion 405 through the cylindrical portion 408b. The coil spring 407 always urges the outlet opening / closing part 408 in a direction away from the outlet forming part 405.

  A protrusion 408c is formed around the cylindrical portion 408b, and a notch 408d with which a claw portion 406a formed on the fixing member 406 is engaged is formed below the protrusion 408c.

  With reference to FIG. 33, the rotation restriction state and the rotation permission state of the outlet opening / closing part 408 will be described. FIG. 33 shows a state where the outlet forming portion 405, the outlet opening / closing portion 408, and the fixing member 406 are assembled.

  State ST11 shows a view of the outlet forming portion 405, the outlet opening / closing portion 408, and the like viewed from two directions in a state where the canister 40 is not attached to the mounting portion 44. The claw portion 406a is engaged with the notch 408d, and the outlet opening / closing portion 408 is restricted from rotating with respect to the outlet forming portion 405 around the central axis of the cylindrical portion 401. The outlet 405a is in a closed state. By the biasing of the coil spring 407, the outlet forming part 405 is biased in the direction away from the outlet opening / closing part 408 as indicated by an arrow. Thereby, the engagement between the notch 408d and the claw portion 406a is strongly maintained. Thus, the notch 408d and the claw portion 406a function as a restriction mechanism that restricts the outlet opening / closing portion 408 from opening the outlet 405a when the canister 40 is not attached to the attachment portion 44.

  State ST12 shows a view of the outlet forming portion 405, the outlet opening / closing portion 408, and the like viewed from two directions in a state where the canister 40 is attached to the attachment portion 44. The mounting portion 44 is provided with an abutting portion (shutter portion 443 described later) that abuts the outlet opening / closing portion 408. By mounting the canister 40 on the mounting portion 44, the outlet opening / closing is resisted against the bias of the coil spring 407. The outlet opening / closing portion 408 is relatively displaced toward the outlet opening / closing portion 408 as indicated by an arrow in the portion 408.

  As a result, the notch 408d is separated from the claw portion 406a and the engagement between the two is released. The outlet opening / closing part 408 is allowed to rotate with respect to the outlet forming part 405 around the central axis of the cylindrical part 401. In the state ST22 of FIG. 33, the outlet 405a is in a closed state, but the outlet 405a can be opened by rotating the outlet opening / closing part 408.

  FIG. 34 is a vertical sectional view including the peripheral structure in a state where the canister 40 is mounted on the mounting portion 44. The mounting portion 44 includes a cup-shaped main body portion 441 into which the end of the canister 40 is inserted. The front side of the main body 441 is opened upward, and the end of the cylindrical portion 401 of the canister 40, the outlet forming portion 405, and the outlet opening / closing portion 408 are accommodated therein, and the rear side thereof is in a lattice shape (rib shape). Is formed.

  A groove 441a with which the protrusion 405b is engaged is formed at the edge of the peripheral wall of the main body 441. A sensor 441b that detects the detection piece 405c is disposed adjacent to the groove 441a. The sensor 441b is, for example, a photo interrupter. When the sensor 441b detects the detection piece 405c, the processing unit 11a recognizes that the canister 40 is attached. If the sensor 441b does not detect the detection piece 405c, the processing unit 11a recognizes that the canister 40 is not attached.

  A receiving portion 442 for receiving roasted coffee beans from the canister 40 is formed on the peripheral wall of the main body portion 441. In the case of this embodiment, the receiving part 442 is an opening communicating with the inside of the conveyor 41. The roasted coffee beans discharged from the outlet 405a of the canister 40 are guided to the conveyor 41 through the receiving portion 442.

  A shutter portion 443 that is a member having a cup shape that fits the outer shape of the outlet opening / closing portion 408 is provided in the main body portion 441. The shutter unit 443 is supported in the main body unit 441 so as to be rotatable around the central axis of the canister 40, and opens and closes the receiving unit 442. In the present embodiment, a plurality of rollers 441d are arranged in the circumferential direction on the peripheral wall of the main body 441 (see FIG. 27). An opening that exposes the roller 441 d to the inside is formed in the peripheral wall of the main body 441. The roller 441 d is supported so as to be rotatable about an axis parallel to the radial direction of the canister 40. The outer peripheral surface of the shutter portion 443 is in contact with a plurality of rollers 441d inside the main body portion 441 and is rotatably supported.

  When the canister 40 is not mounted, the shutter unit 443 closes the receiving unit 442 to prevent foreign matter from entering the conveyor 41. FIG. 34 shows a state where the shutter portion 443 closes the receiving portion 442. After the canister 40 is mounted, the shutter portion 443 can be rotated by driving the motor 41a to open the receiving portion 442.

  The shutter portion 443 is attached to the rotating member 444. The rotating member 444 operates the outlet opening / closing part 408 to rotate to open / close the outlet 405a. The rotating member 444 is connected to the drive shaft 445. When the canister 40 is mounted, the drive shaft 445 is disposed so as to be coaxial with the central axis thereof, and is one of the elements that transmits the driving force of the motor 41a to the rotating member 444. The rotating member 444 is a cylindrical member that opens upward on the front side. A groove 444a is formed at the edge of the peripheral wall of the rotating member 444, and the protrusion 408c of the outlet opening / closing part 408 engages with the groove 444a. By this engagement, when the rotating member 444 is rotated, the outlet opening / closing portion 408 is also rotated, and the outlet 405a is opened / closed. FIG. 34 shows a state where the outlet opening / closing unit 408 closes the outlet 405a.

  With the above configuration, the rotation of the rotating member 444 causes the shutter portion 443 to close the receiving portion 442 and the outlet opening / closing portion 408 to close the outlet 405a (state in FIG. 34, referred to as a closed state). The shutter 443 opens the receiving unit 442 and the outlet opening / closing unit 408 opens the outlet 405a (a state in which roasted coffee beans are supplied into the apparatus, referred to as an open state). The state of the storage device 4 can be switched. These states can be recognized by the processing unit 11a by detecting the rotational position of the shutter unit 443 by a sensor (not shown) (feedback control). As another example, a stepping motor may be used as the motor 41a, and the state of the storage device 4 may be recognized and switched using the control amount (number of steps) (open loop control).

  The drive shaft 445 is provided with a bevel gear 445 a, and the bevel gear 445 a meshes with a bevel gear 445 b provided on the drive shaft 46.

  The drive shaft 46 is provided with a gear 45b that meshes with a pinion gear 45a provided on the output shaft of the motor 41a, and rotates by driving of the motor 41a. A one-way clutch 445c is interposed between the drive shaft 46 and the bevel gear 445b. The one-way clutch 445c transmits only the rotation of the drive shaft 446 in one direction to the bevel gear 445b. That is, when the motor 41a is rotated in one direction, the driving force of the motor 41a is transmitted to the rotating member 444 through the path of the bevel gear 445b, the bevel gear 445a, and the drive shaft 445. Is not transmitted when it rotates in the other opposite direction.

  The conveyor 41 is a transport mechanism that transports roasted coffee beans from the canister 40. In this embodiment, the conveyor 41 is provided not on the canister 40 side but on the mounting portion 44 side. That is, the conveyor 41 is provided so as to remain on the mounting portion 44 side when the canister 40 is removed from the mounting portion 44. Although a configuration in which the canister 40 and the conveyor 41 are integrated can be adopted, the canister 40 can be simplified and reduced in weight by being configured separately as in the present embodiment.

  The screw shaft of the conveyor 41 is connected to the drive shaft 46 through a one-way clutch 47a. The drive transmission direction of the one-way clutch 47a is opposite to that of the one-way clutch 445c. That is, when the motor 41a is rotated in the other direction, the driving force of the motor 41a is transmitted to the screw shaft 47 and the roasted coffee beans are conveyed, but the motor 41a is rotated in one direction opposite to this. Is not transmitted.

  Thus, in this embodiment, the rotation direction of the motor 41a is switched between forward and reverse to exclusively rotate the rotation member 444 (that is, rotation of the shutter unit 443 and the outlet opening / closing unit 408) and the screw shaft 47. be able to.

  A control example of the processing unit 11a related to the mounting and removal of the canister 40 will be described. When the canister 40 is mounted on the mounting portion 44 by the user, this is detected by the sensor 441b. The processing unit 11a drives the motor 41a to open the shutter unit 443 and the outlet opening / closing unit 408. The protrusion 408 c engages with the stopper 441 c provided on the inner peripheral wall of the main body 441 and the axial direction of the canister 40, so that the canister 40 does not fall off the mounting portion 44 even if the user releases the hand. In other words, the protrusion 408c functions as a restricting portion that restricts the canister 40 from being removed from the mounting portion 44 when the outlet opening / closing portion 408 opens the outlet 405a. Thereby, it can prevent that the canister 40 is removed and the roasted coffee beans in the canister 40 spill out while the outlet 405a is opened.

  As the shutter unit 443 and the outlet opening / closing unit 408 are opened, the roasted coffee beans in the canister 40 are introduced into the conveyor 41 through the receiving unit 442. Wait in this state.

  When producing a coffee beverage, the motor 41a is driven to rotate and stop the screw shaft 47. Thereby, roasted coffee beans are conveyed to the collective conveyance path 42. Depending on the amount of rotation of the screw shaft 47, the amount of roasted coffee beans used for the production of a coffee beverage is automatically weighed. When a plurality of roasted coffee beans are blended to produce a coffee beverage in one coffee beverage production, the ratio of the amount of conveyance to the collective conveyance path 42 by the conveyor 41 is changed between the canisters 40. Also good. Thereby, ground beans in which a plurality of types of roasted coffee beans are blended can be supplied to the extraction container 9.

  When replacing the canister 40, the user gives an exchange instruction from the operation unit 12. The processing unit 11a drives the motor 41a to return the shutter unit 443 and the outlet opening / closing unit 408 to the closed state. The user can remove the canister 40 from the mounting portion 44.

<Canister and its detachable structure (second example)>
A canister 40 and mounting portion 44 of a second example partially different from the canister 40 and mounting portion 44 of the first example described with reference to FIGS. 31 to 34 will be described with reference to FIGS. Among the configurations of the second example, the same configurations as those of the first example or configurations having common functions are denoted by the same reference numerals as those of the configurations of the first example, and description thereof is omitted. Explained.

  35 to 37 show external views of the canister 40 and the mounting portion 44 of the second example viewed from multiple directions. In the main body 441 of the mounting portion 44 of the first example, it has been described that the rear side is formed in a lattice shape (rib shape). However, the structure is the same as that of the main body portion 441 of the second example. It is understood from 36 etc. The rear side of the main body 441 is composed of a plurality of ribs 441e, and the inner rotating member 444 and the like are visible.

  The rotating member 444 has two detection pieces 444b that are separated by 180 degrees in the circumferential direction. Two sensors 441f such as a photo interrupter are provided and detect two detection pieces 444b. The processing unit 11a recognizes the rotational position of the rotating member 444 based on the detection result of the sensor 441f. That is, it is recognized whether the shutter unit 443 and the outlet opening / closing unit 408 described in the first example are in a closed state or an open state.

  FIG. 38 is a vertical sectional view including the peripheral structure in a state where the canister 40 is mounted on the mounting portion 44. The structure of the second example is basically the same as that of the first example, but an elastic deformation portion 405d is formed on the peripheral wall of the outlet forming portion 405 at the periphery of the outlet 405a. The elastic deformation part 405 is a part formed by inserting a slit parallel to the peripheral wall of the outlet forming part 405 from the peripheral edge of the outlet 405a, and is thus configured to be more easily deformed than the surrounding part. The function of the elastic deformation portion 405d will be described later.

  The second example is different from the first example in the configuration related to the rotation restriction and rotation permission of the outlet opening / closing part 408. This point will be described with reference to FIGS. A state ST1 in FIG. 39 shows a case where the outlet opening / closing part 408 is in a rotation restricted state, and a state ST22 in FIG. 39 shows a case where the outlet opening / closing part 408 is in a rotation-permitted state. 40 is a cross-sectional view taken along line II-II in FIG. 39, and states ST21 and ST22 in FIG. 39 correspond to states ST21 and ST22 in FIG.

  In the second example, the coil spring spring 407 of the outlet forming portion 405 and the claw portion 406a of the fixing member 406 in the first example are not provided, and the outlet opening / closing portion 408 is in the axial direction of the cylindrical portion 401 with respect to the outlet forming portion 405. Relative displacement is possible only around this axis.

  The scale SC of the second example has a groove GR, and a slider 409 is incorporated therein. The slider 409 is configured by fastening a front side member and a back side member of the scale SC with two bolts, and is slidable in the longitudinal direction of the scale SC along the groove GR. As a configuration corresponding to the protrusion 405b and the detection piece 405c in the first example, the slider 409 includes a protrusion 405b 'and a detection piece 405c'. The slider 409 also has a grip portion NB for the user to grip with the fingertip.

  The slider 409 has a convex portion 409a that can be engaged with either the concave portion CT1 or CT2 formed in the scale SC. The slider 409 is slidable between a first position where the convex portion 409a engages with the concave portion CT1 and a second position where the convex portion 409a engages with the concave portion CT2. A state ST21 and a state ST22 indicate a state where the slider 409 is positioned at the first position, and a state ST23 of FIG. 40 indicates a state where the slider 409 is positioned at the second position. The slider 409 is basically located at the first position, and is manually slid to the second position when releasing the roasted coffee beans to be described later.

  At the end of the scale SC of the second example, a cylindrical support portion SC ′ that opens to the outlet forming portion 405 side is fixed. The support portion SC 'supports a coil spring spring 407 of the first example, a coil spring spring 407' instead of the claw portion 406a, and a movable member 406a '. At the edge of the outlet opening / closing portion 408, a notch 408d 'is formed instead of the notch 408d of the first example. As shown in state ST21, when the movable member 406a 'engages with the notch 408d', the outlet opening / closing part 408 is restricted from rotating with respect to the outlet forming part 405 around the central axis of the cylindrical part 401. At this time, the outlet 405a is in a closed state. The movable member 406a 'is constantly urged toward the notch 408d' by the coil spring 407 '. Thereby, the engagement between the notch 408d 'and the movable member 406a' is strongly maintained. Thus, the notch 408d 'and the movable member 406a' function as a regulating mechanism that regulates that the outlet opening / closing part 408 opens the outlet 405a when the canister 40 is not attached to the mounting part 44.

  When the canister 40 is mounted on the mounting portion 44, as shown in the state ST22, the movable member 406a ′ comes into contact with the edge of the shutter portion 443 and is pushed into the support portion SC ′ against the bias of the coil spring 407 ′. It is. As a result, the engagement between the movable member 406 a ′ and the notch 408 d ′ is released, and the outlet opening / closing part 408 is allowed to rotate with respect to the outlet forming part 405 around the central axis of the cylindrical part 401.

  A control example of the processing unit 11a related to mounting and removal of the canister 40 in the second example will be described mainly with reference to FIGS. When the canister 40 is mounted on the mounting portion 44 by the user, the movable member 406a ′ comes into contact with the edge of the shutter portion 443, and thereby the engagement between the movable member 406a ′ and the notch 408d ′ is released ( State of state ST22).

  The mounting of the canister 40 is detected by the sensor 441b, and the processing unit 11a drives the motor 41a to open the shutter unit 443 and the outlet opening / closing unit 408. A state ST31 in FIG. 41 illustrates a case where the outlet opening / closing portion 408 is in a closed state, and a state ST32 illustrates a case where the outlet opening / closing portion 408 is shifted from the state ST31 to an open state.

  When the shutter portion 443 and the outlet opening / closing portion 408 are in the open state, the protrusion 408c engages with the stopper 441c provided on the inner peripheral wall of the main body portion 441 in the axial direction of the canister 40, so that the canister can be operated even if the user releases the hand. 40 does not fall off the mounting portion 44. In other words, the protrusion 408c functions as a restricting portion that restricts the canister 40 from being removed from the mounting portion 44 when the outlet opening / closing portion 408 opens the outlet 405a. Thereby, it can prevent that the canister 40 is removed and the roasted coffee beans in the canister 40 spill out while the outlet 405a is opened.

  As the shutter unit 443 and the outlet opening / closing unit 408 are opened, the roasted coffee beans in the canister 40 are introduced into the conveyor 41 through the receiving unit 442. Wait in this state.

  When producing a coffee beverage, the motor 41a is driven to rotate and stop the screw shaft 47. Thereby, roasted coffee beans are conveyed to the collective conveyance path 42. Depending on the amount of rotation of the screw shaft 47, the amount of roasted coffee beans used for the production of a coffee beverage is automatically weighed.

  A bean remaining amount detection sensor SR is provided at the base of the receiving unit 442. The remaining bean amount detection sensor SR is, for example, a transmissive sensor (photo interrupter). If the coffee beverage is manufactured a predetermined number of times (for example, two cups) after it is detected that there is no bean at this position, it may be notified that the contents of the canister 40 are empty.

  When replacing the canister 40, for example, the user gives a replacement instruction from the operation unit 12. The processing unit 11a drives the motor 41a to return the shutter unit 443 and the outlet opening / closing unit 408 to the closed state. A state ST33 in FIG. 41 illustrates a state in which the outlet opening / closing unit 408 returns from the state ST32 to the closed state.

  When the shutter portion 443 and the outlet opening / closing portion 408 are in the closed state, the engagement between the protrusion 408 c and the stopper 441 c is released, and the user can remove the canister 40 from the mounting portion 44. When the canister 40 is removed from the mounting portion 44, the movable member 406a 'is engaged with the notch 408d' again by the biasing force of the coil spring 407 '(state in the state ST21). As a result, the rotation of the outlet opening / closing part 408 relative to the outlet forming part 405 around the central axis of the tubular part 401 is again restricted, and roasted coffee beans remaining in the canister 40 may be accidentally spilled from the outlet 405a. Is prevented.

<Countermeasures for biting>
When the shutter portion 443 and the outlet opening / closing portion 408 are returned from the open state to the closed state, the exposure degree (opening area) of the outlet 405a gradually becomes narrower as it overlaps the peripheral wall of the outlet opening / closing portion 408. Below the broken line in FIG. 41, a change in the degree of exposure of the outlet 405a is shown in the process of returning the outlet opening / closing part 408 from the open state to the closed state.

  The peripheral edge ED1 of the outlet forming portion 405 that defines the outlet 405a and the peripheral wall edge ED2 of the outlet opening and closing portion 408 that are both bulged in a direction facing each other, and It is made into the shape where the width | variety of the exit 405a becomes wide at the cylinder part 401 side. Thereby, the roasted coffee beans located between the edge ED1 and the edge ED2 are easily pushed out to the tube portion 401 side, and it is difficult for the beans to be bitten at a plurality of points. The edges ED1 and ED2 may not be bulged, but may be shaped so that the width of the outlet 405a is widened on the cylindrical portion 401 side while being straight.

  Since the end portion of the edge ED1 is formed by the elastic deformation portion 405d, when the roasted coffee beans are about to be bitten between the elastic deformation portion 405d and the edge ED2 just before the outlet 405a is closed, the elastic deformation portion The portion 405d is deformed and beans are easily repelled. This further prevents the roasted coffee beans from being bitten.

  Next, a control example relating to prevention of biting of roasted coffee beans will be described. 42 to 44 are sectional views of the canister 40 in the radial direction, and illustrate the state of roasted coffee beans to be accommodated. 42 to 44 exemplify the control from installation to removal of the canister 40. FIG.

  FIG. 42 shows a state immediately after the canister 40 is mounted on the mounting portion 44. The shutter part 443 and the outlet opening / closing part 408 are in a closed state. FIG. 43 shows a state where the shutter unit 443 and the outlet opening / closing unit 408 are switched to the open state from the state of FIG. The outlet 405a and the receiving part 442 are opened, and roasted coffee beans have flowed into the conveyor 41.

  FIG. 44 shows a state where the shutter portion 443 and the outlet opening / closing portion 408 return to the closed state again. Before the exit 405a is completely closed, the rotation of the shutter portion 443 and the exit opening / closing portion 408 is once stopped. The outlet 405a is partially closed, and is opened to such an extent that, for example, one roasted coffee bean can pass through. When the motor 41a is a stepping motor, the opening degree of the outlet 405a can be controlled by the control amount (number of steps).

  In this state, the conveyor 41 is driven to remove roasted coffee beans from the periphery of the receiving unit 442. Then, the conveyor 41 is stopped, the shutter part 443 and the exit opening / closing part 408 are all closed, and are completely returned to the closed state. Thereby, it can prevent more reliably biting roasted coffee beans.

  As shown in FIGS. 42 to 44, the cross-sectional shapes of the edges of the outlet forming portion 405, the outlet opening / closing portion 408, and the shutter portion 443 have a wedge shape or a tapered shape. Since the contact area between the roasted coffee beans and the edge becomes small, it contributes to prevention of biting.

  Further, as shown in the cross-sectional views of FIGS. 34 and 38, the space around the receiving portion 442 has a larger volume on the front side than on the rear side. Thereby, when returning the shutter part 443 and the exit opening-and-closing part 408 from an open state to a closed state, the space around the exit 405a which becomes narrow gradually can be ensured more, and biting of roasted coffee beans can be prevented. By narrowing the rear side, roasted coffee beans remaining here can be reduced, and when the conveyor 41 is driven in the state of FIG. 44, roasted coffee beans (for example, discarded) carried out by the conveyor 41 ) Can be reduced.

  45 to 47 are also cross-sectional views of the canister 40 in the radial direction, and illustrate the state of roasted coffee beans to be accommodated. FIGS. 45 to 47 exemplify a case where the shutter unit 443 and the outlet opening / closing unit 408 are returned from the open state to the closed state with a relatively large amount of roasted coffee beans remaining in the receiving unit 442 and the canister 40. Yes.

  FIG. 45 shows a case where the shutter unit 443 and the outlet opening / closing unit 408 are in an open state. A relatively large amount of roasted coffee beans stays in the vicinity of the outlet 405a and the receiving portion 442.

  FIG. 46 shows a state in which the shutter unit 443 and the outlet opening / closing unit 408 are returned to the closed state. Similarly to the example of FIG. 44, the rotation of the shutter portion 443 and the outlet opening / closing portion 408 is once stopped before the outlet 405a is completely closed. In this state, the conveyor 41 is driven to remove roasted coffee beans from the periphery of the receiving unit 442. Thereafter, the conveyor 41 is stopped, and the shutter portion 443 and the outlet opening / closing portion 408 are completely returned to the closed state. However, roasted coffee beans may be bitten as shown in FIG.

  For example, when it is not confirmed that the shutter unit 443 and the outlet opening / closing unit 408 have returned to the closed state within a predetermined time, the processing unit 11a notifies the user of the occurrence of biting. In many cases, the roasted coffee beans can be eliminated by slightly widening the outlet 405a. Therefore, it is only necessary to manually rotate the outlet forming portion 405 (cylinder portion 401) to slightly widen the outlet 405a. However, when the canister 40 is mounted on the mounting portion 44, the outlet forming portion 405 (cylinder portion 401) cannot be manually rotated due to the engagement between the protruding portion 405b 'and the groove 441a.

  Therefore, as shown in a state ST23 in FIG. 40, the user manually slides the slider 409 to the second position. As a result, the protrusion 405b 'is released from the groove 441a, and the engagement between the two is released. The exit formation part 405 (cylinder part 401) can be manually rotated to eliminate biting. Thereafter, the user manually returns the slider 409 to the first position, and instructs the operation unit 12 to resume the operation to the closed state. The processing unit 11a drives the motor 41a to completely return the shutter unit 443 and the outlet opening / closing unit 408 to the closed state.

<Acceptance section and assembly transport path>
The storage device 4 may include a receiving unit at a site different from the mounting unit 44 apart from the receiving unit 442 for each mounting unit 44. An example of the configuration will be described again with reference to FIG.

  In the example of FIG. 27, a receiving part 42c different from the receiving part 442 is provided. The receiving portion 42 c is an opening formed in the front wall portion of the collective conveyance path 42. The user can put the roasted coffee beans into the collective conveyance path 42 by hand or by using a funnel-like tool from the receiving portion 42c. The inputted roasted coffee beans are supplied to the crushing device 5 from the discharge port 42b by their own weight, and the coffee beverage can be manufactured.

  This receiving part 42c can be utilized when manufacturing a coffee drink using the special roasted coffee beans which are not accommodated in the canister 40, for example. The manufacturing process program used for manufacturing such a special cup of coffee beverage may be selectable, or may be a manufacturing process program that operates under manufacturing conditions set by the user.

  As described above, in the present embodiment, the receiving unit 442 that receives the supply of roasted coffee beans from the canister 40 and the receiving unit 42c that receives the supply of roasted coffee beans individually provide the same type by the receiving unit 442. It is possible to provide the beverage manufacturing apparatus 1 that can meet individual needs by the receiving unit 42c while ensuring the mass productivity of the coffee beverage.

  In the case of the present embodiment, the grinding device 5 (especially coarse particles) from the receiving unit 42c rather than the supply path RT1 (see FIG. 34 in addition to FIG. 27) from the receiving unit 442 to the grinding device 5 (especially the coarse grain grinder 5A). The supply route RT2 to the grinder 5A) has a shorter route length. When roasted coffee beans are introduced from the receiving part 42c, the coffee beans are generally dropped directly into the discharge port 42b and supplied to the crushing device 5. This can more reliably supply the entire amount of the roasted coffee beans that have been charged to the crushing device 5, and can suppress the waste of beans and the occurrence of weighing errors. The supply route RT2 is a route that joins in the middle of the supply route RT1. The structure can be made simpler than the configuration in which the paths are completely independent from each other.

  The conveyor 41 does not exist on the supply path RT2, and therefore roasted coffee beans input from the receiving unit 42c are not automatically weighed. For this reason, the user can measure coffee freely and can produce a coffee beverage by putting a desired amount of roasted coffee beans from the receiving portion 42c. However, it is also possible to provide a mechanism for automatically weighing roasted coffee beans on the supply path RT2.

  The collective conveyance path 42 of the present embodiment has a front wall inclined forward and upward, and is disposed in an inclined posture as a whole. By tilting, it becomes easy to receive roasted coffee beans in the receiving part 42c, and roasted coffee beans conveyed from the conveyor 41 can also be directed to the crushing device 5.

  Since the receiving part 42c is an opening part, it is also possible to visually check the state of the conveyor 41 through the receiving part 42c. That is, the receiving part 42c can also be used as an inspection window.

  Hereinafter, another example of the collective conveyance path 42 and the receiving unit 42c will be described.

  In the example of FIG. 48, two receiving portions 42c are provided. Thus, a plurality of receiving portions 42c may be provided. One receiving part 42c is provided with a lid 42d configured to be opened and closed by a hinge 42e. When not in use, it is possible to prevent foreign matter from entering the collective conveyance path 42 by closing the receiving portion 42 with the lid 42d. The part where the hinge 42e is provided may be on the upper side, the lower side, the back side, or the front side of the lid 42d. The other receiving portion 42c is formed by a hopper-like tube member 42f.

  The tube member 42f may be separable from the collective conveyance path 42 as shown in FIG. The opening 42g is a hole for attaching the pipe member 42f.

When an empty canister 40 (or a canister 40 supplemented with new beans) is mounted on the stocker 130, information on roasted coffee beans stored in the canister 40 can be stored in the tag TG from the writer. By doing in this way, it is not necessary for the roasted coffee beans and the canister 40 to be linked one-on-one. As a method for registering information, for example, information may be transmitted to the stocker 130 from a portable terminal. As another method, the tag TG of the roasted coffee bean storage bag 120 (FIG. 59) may be read and registered by a reader attached to the stocker 130.

<Sixth embodiment>
The configuration of the grinder 5B of the third embodiment will be described in detail. The configuration of the grinder 5B described below can also be applied to the grinder 5A.

  FIG. 62 is an external view of the grinder 5B. FIG. 63 is an explanatory view of the attachment / detachment mode of the grinder 5B, and schematically shows the structure of the grinder 5B. A state ST31 in FIG. 63 shows a mounted state, and a state ST32 shows a separated state.

  The grinder 5B includes a motor 52b, a motor base 502, a main body 53b, and a particle size adjusting mechanism 503.

  The motor 52b is a drive source of the grinder 5B and is supported on the motor base 502. The motor base 502 contains a pinion gear 52b 'fixed to the output shaft of the motor 52b and a gear 502a meshing with the pinion gear in a hollow case.

  The main body 53b is a unit that accommodates a cutter, and a housing that forms the outer shape thereof is configured by a base 505a, a gear case 505b, and a blade case 505c, and these three members are fastening bolts or the like. It is fixed by a member 505d. When the fastening member 505d is removed, they can be separated from each other, and the maintenance inside thereof is facilitated.

  The gear case portion 505b accommodates a gear 55b 'that meshes with the gear 502a. A rotation shaft 54b is fixed to the gear 55b ', and the rotation shaft 54b is rotatably supported by the gear case portion 505b. The driving force of the motor 52b transmitted to the gear 55b 'via the gear 502a rotates the rotating shaft 54b. A rotary blade 58b is provided at the end of the rotary shaft 54b, and a fixed blade 57b is provided above the rotary blade 58b. The fixed blade 57b and the rotary blade 58b are accommodated in the blade case portion 505c.

  The particle size adjusting mechanism 503 is provided in the main body 53b. The particle size adjusting mechanism 503 includes a motor 503a which is a driving source thereof and a worm gear 503b which is rotated by a driving force of the motor 503a.

  The gear 53b 'is provided with an adjustment shaft 503c that extends in the vertical direction on the rotation center of the gear 53b'. The adjusting shaft 503c and the fixed blade 57b are formed with gears that mesh with each other. When the adjusting shaft 503c is rotated, the fixed blade 57b moves up and down in the axial direction. Thereby, the clearance gap between the rotary blade 58b and the fixed blade 57b can be adjusted, and the particle size of the ground beans in the grinder 5B can be adjusted. The method for adjusting the gap between the fixed blade 58b and the fixed blade 57b is not limited to this, and the position of the adjustment shaft 503c may not be on the center of rotation.

  The delivery pipe 501 is configured to be detachable from the main body 53b. In this embodiment, the delivery pipe 501 is provided with an engaging portion 501a, and the gear case portion 505b is provided with an engaging portion 505e that engages with the engaging portion 501a. As shown in the state ST31 of FIG. 63, the engaging portion 501a is engaged with the engaging portion 505e from above, and both are engaged, and when the engaging portion 501a is extracted upward, the engagement is released. In the engaged state, the delivery pipe 501 communicates with an opening (a ground bean outlet) formed in the peripheral wall of the blade case portion 505c. Since the delivery pipe 501 is detachable from the main body 53b, maintenance or replacement such as clogging of the delivery pipe 501 and cleaning of the main body 53b are facilitated. Note that the shape of the opening of the delivery pipe 501 does not have to be a circle, but may be a square or a figure having an indented middle of a circle.

  The base portion 505a and the motor base 502 are fixed to each other by a fastening member 504 such as a bolt. When the fastening member 504 is removed, the main body 53b is separated from the motor base 502 and the motor 52b as shown in a state ST32 in FIG. That is, when the main body 53b is removed, the motor base 502 and the motor 52b remain on the beverage production device 1 side (the pulverization device 5 side). Since only the main body 53b can be removed, it becomes easier to clean the main body 53b that is easily soiled by the ground beans. Maintenance can be facilitated. Moreover, since the motor base 502 and the motor 52b remain on the side of the beverage production apparatus 1, it is not necessary to remove the electrical wiring or the like. Therefore, maintenance is facilitated.

  In this embodiment, the motor base 502 is overlaid on the base portion 505a and fastened by the fastening member 504. Conversely, the base portion 505a is overlaid on the motor base 502.

However, the particle size adjusting mechanism 503 may be configured to remain on the side of the beverage production apparatus 1 (the side of the crushing apparatus 5), or the motor 503a. Only the structure which remains in the drink manufacturing apparatus 1 side (the side of the crushing apparatus 5) may be sufficient. Moreover, the base part 505a, the gear case part 505b, and the blade case part 505c may be separable from each other by separating the main body part 53b from the beverage manufacturing apparatus 1 side. When the base portion 505a is removed from the gear case portion 505b and the mechanism (for example, the gear 55b ′, the rotating shaft 54b, etc.) inside the main body portion 53b is to be checked and maintained, the main body portion 53b is attached to the beverage production apparatus 1 (for example, , The motor base 502 or the like) is not possible unless it is removed. In addition, the fastening member 504 that attaches the main body 53b to the beverage production apparatus 1 (for example, the motor base 502) is removed downward, and the user views the main body 53b from above or obliquely from above. In addition, it is impossible to visually recognize whether or not the fastening member 504 is attached from the outside of the housing 100 via the transmission part 101, and the user cannot easily remove the main body part 53b and perform maintenance. Note that a manufacturer's maintenance person who knows the position of the fastening member 504 can confirm whether or not the fastening member 504 is attached from the outside of the housing 100 via the transmission part 101 from obliquely below. .

  In the case of this embodiment, the gear case portion 505b and the blade case portion 505c are each provided with an engaging portion 506 and configured to engage with the motor base 502. Two sets of the engaging portions 506 are provided so as to be separated from each other on the left and right. FIG. 64 is an explanatory diagram thereof. A state ST41 in FIG. 64 shows a state in which the main body 53b is removed from the motor base 502, a state ST42 shows a state in the middle of engaging them, and a state ST43 shows a state in which these engagements are completed.

  The engaging portion 506 has an arm shape extending rearward and engages with an engaging portion 502 b provided on the motor base 502. The engaging portion 502b extends in the vertical direction and has an insertion portion into which the engaging portion 506 is inserted.

  As shown in FIG. 64, when attaching the main body portion 53b to the motor base 502, the engaging portion 506 is assembled so as to be inserted into the engaging portion 502b in the front-rear direction, and the main body portion 53b is lifted. A taper surface 502c having a slope extending upward is formed at the rear end portion of the engaging portion 502b, and the end portion of the engaging portion 506 comes into contact therewith. The tapered surface 502c acts to open the engaging portion 506 in the front-rear direction, and the main body portion 53b and the motor base 502 are assembled without backlash in the front-rear direction by the elastic deformation force. Thereafter, the fastening member 504 is attached to the main body 53b and the motor base 502 to fasten them. Due to the engagement between the engagement portion 506 and the engagement portion 502d, an elastic force that separates the main body portion 53b and the motor base 502 in the front-rear direction acts, and a load in the vertical direction is applied via the engagement portion 506 and the engagement portion 502d. Thus, the motor base 502 can be burdened. For this reason, it is difficult for the main body 53b to drop off from the motor base 502, and the fixing load of the fastening member 504 can be reduced. Note that the taper may be provided in the engaging portion 506.

  FIG. 65 shows a modification of the example of FIG. In this modification, the upper and lower arrangements of the engaging portion 506 and the engaging portion 502b are reversed, and the other configurations are the same. When the main body 53b is attached to the motor base 502, the end of the engaging portion 506 is brought into contact with the tapered surface 502c by pushing down the main body 53b instead of lifting the main body 53b as in the example of FIG. become. The tapered surface 502c acts to open the engaging portion 506 in the front-rear direction, and the elastic deformation force allows the main body portion 53b and the motor base 502 to be assembled without backlash in the front-rear direction, similar to the example of FIG. . State ST51 shows a state in which main body 53b is removed from motor base 502, state ST52 shows a state in the middle of engaging them, and state ST53 shows a state in which these engagements have been completed.

  In this example, the taper surface 502c is not essential in that the load in the vertical direction is borne on the motor base 502, and a configuration without this can also be employed. Further, in this example, the length of the engaging portion 502b in the height direction is made longer than the engaging portion 506 (for example, twice or more), so that the main body portion 53b has its own weight and is indicated by an arrow 507 in the state ST53 in FIG. Thus, it can be prevented from coming off while rotating.

  In addition, when this embodiment is combined with 4th embodiment, all or one part of the main-body part 53b may be visually recognized from the exterior via the permeation | transmission part 101. FIG. Thereby, it becomes easy to confirm the necessity of the maintenance of the main body 53b. Conversely, in a state where the main body portion 53b is attached to the motor base 502, the motor 52b may not be visible from the outside via the transmission portion 101. In some cases, it is advantageous in terms of design that a portion related to a mechanism such as the motor 52b cannot be visually recognized. Similarly, in a state where the main body portion 53b is attached to the motor base 502, the motor 503a may not be visible from the outside via the transmission portion 101.

<Seventh embodiment>
Another configuration example of the extraction container 9 will be described. FIG. 66 is a cross-sectional view of the extraction container 9 of the present embodiment, showing a state where it is locked by the gripping member 821a. FIG. 67 is an explanatory diagram of a guide function for automatically centering the container main body 90 and the lid unit 91.

  In the extraction container 9 of the present embodiment, a guide portion 911e and a guide portion 90g are provided on the flange portion 911c and the flange portion 90c, respectively. When the lid unit 91 closes the opening 90a, one of these guide portions 911e and 90g guides the other to automatically center the container body 90 and the lid unit 91.

  In the case of this embodiment, the guide part 911e is an annular groove formed over the entire circumference of the flange part 911c. The cross-sectional shape of this groove is a triangle and opens downward (toward the container body 90). The guide portion 90g is an annular rib formed over the entire circumference of the flange portion 90c. The rib protrudes upward (toward the lid unit 91) from the flange portion 90c, and is inclined corresponding to the inclination of the inner surface of the guide portion 911e.

  FIG. 67 illustrates a case where the opening 90a is closed from the state where the lid unit 91 is separated from the opening 90a. In the case of the example in the figure, a state in which the lid unit 91 is shifted by a minute amount from the center line CLc of the container main body 90 is shown. The center of the lid unit 91 is the axis of the shaft 913a.

  As shown in FIG. 67, when the lid unit 91 is displaced from the center line CLc of the container main body 90, the guide portion 90g is inclined on the radially inner side of the guide portion 911e when it is overlapped with the flange portion 911c and the flange portion 90c. At least one of the lid units 91 is slightly displaced in the lateral direction so that the center of the lid unit 91 is aligned with the center line CLc of the container main body 90 by the guide. Thereby, the container main body 90 and the lid unit 91 are automatically centered.

  In this embodiment, the guide portion 911e is a groove and the guide portion 90g is a rib, but these may be reversed. Moreover, the shape of the guide part 911e and the guide part 90g can also be selected suitably.

  In the case of this embodiment, the cross-sectional shape of the gripping member 821a is rectangular like the example of FIG. 17, and the upper inner surface US that forms the upper side of the cross-sectional shape and the lower inner surface LS that forms the lower side of the cross-sectional shape are mutually Parallel. In the locked state, the upper inner surface US is in contact with a portion (contact surface) 911c 'of the upper surface of the flange portion 911c, and the lower inner surface LS is in contact with a portion (contact surface) 90c' of the lower surface of the flange portion 911c. In the locked state, in the case of the present embodiment, the upper inner surface US, the lower inner surface LS, and the contact surface 911c ′ and the contact surface 90c ′ are parallel to each other and orthogonal to the center line CLc. When the inside of the extraction container 9 is pressurized, forces are applied to the lid unit 91 and the container body 90 in the vertical direction (more precisely, in the direction of the center line CLc). Since the upper inner surface US, the lower inner surface LS, the contact surface 911c ′ and the contact surface 90c ′ are parallel to each other, a component force in a direction to open the pair of gripping members 821a to the left and right acts as a component force of the separating force. It becomes difficult and can maintain a locked state more reliably.

<Eighth embodiment>
A liquid supply amount adjusting device that replaces the water tank 72 of the first embodiment will be described. 68 is a schematic diagram of the liquid feeding amount adjusting device 720 of this embodiment, and FIG. 69 is a sectional view taken along the line IV-IV of FIG. 68 and another sectional view (configuration example EX31). Similarly to the water tank 72, the liquid feeding amount adjustment device 720 is a tank that accumulates hot water (water) that constitutes a coffee beverage, and is a device that has a function of delivering a certain amount of hot water. Thereby, hot water required for one cup of coffee drink is sequentially sent out. In addition, the amount of hot water to be delivered can be changed. In the following description, components having the same functions as those related to the water tank 72 are denoted by the same reference numerals.

  The liquid feeding amount adjusting device 720 has a tank 720a for accumulating hot water. The outer wall of the tank 720a includes a peripheral wall 721, an upper wall 723 joined to the upper end portion of the peripheral wall 721, and a bottom wall 724 joined to the lower end portion of the peripheral wall 721. As shown in the sectional view of FIG. Has a cylindrical shape as a whole. A partition wall 722 is provided in the tank 720a, and its internal space is partitioned by the partition wall 722 into an outer cylindrical space 725 and an inner columnar space 726A. In the case of this embodiment, the partition wall 722 is a cylindrical wall body arranged concentrically with the peripheral wall 721. However, even if the partition wall 722 is eccentric with respect to the peripheral wall 721 as shown in the configuration example EX31 of FIG. Good.

  The space 725 constitutes a storage unit that stores hot water. The space 725 is also referred to as a storage unit 725. A movable member 727c is arranged in the upper part of the space 726A, and the lower space 726 constitutes a storage part for storing hot water. The space 726 is also referred to as a storage unit 726. By partitioning the storage portion 725 and the storage portion 726 with a partition wall 722 that is a common wall body, the tank 720a can be downsized rather than being partitioned by separate wall bodies.

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

  The upper wall 723 is connected to a portion that delimits the storage portion 725 by a pipe to which the air pressure in the reserve tank 71 (see FIG. 1) is supplied. An electromagnetic valve 72f is provided here. The liquid feeding amount adjusting device 720 includes a sensor (not shown; for example, a sensor corresponding to the pressure sensor 72g in FIG. 1) that detects the atmospheric pressure in the reservoir 725, and the electromagnetic valve 72f is a pressure regulating valve 72e (see FIG. 1). The supply and shutoff of the regulated atmospheric pressure to the storage unit 725 are switched. The electromagnetic valve 72f is controlled to be opened and closed so that the atmospheric pressure in the reservoir 725 is maintained at 3 atm, except when the tap water is supplied to the reservoir 725.

  A portion of the upper wall 723 that defines the storage portion 725 is connected to a pipe that communicates the storage portion 725 with the atmosphere, and an electromagnetic valve 72h is provided here. When supplying tap water to the reservoir 725, the pressure in the reservoir 725 is reduced to less than 2.5 atm by the electromagnetic valve 72h so that the tap water is smoothly supplied to the reservoir 725 by the water pressure of the tap water. The electromagnetic valve 72h switches whether or not the inside of the water tank 72 is released to the atmosphere, and releases the inside of the storage unit 725 to the atmosphere during decompression. Further, the electromagnetic valve 72h releases the storage unit 725 to the atmosphere and maintains the storage unit 725 at 3 atm when the atmospheric pressure in the storage unit 725 exceeds 3 atm. .

  A pipe L2 for supplying tap water to the reservoir 725 is connected to a portion of the bottom wall 724 that defines the reservoir 725, and an electromagnetic valve 72d is provided here. The electromagnetic valve 72d is controlled to open and close based on a detection result of a water level sensor 72c described later, and controls the water level of hot water in the reservoir 725.

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

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

  In the present embodiment, the electromagnetic valve 728 is a three-way valve, and can perform switching between communication and blocking between the pipe 728b and the pipe 728a and switching between communication and blocking between the pipe 728b and the pipe 728c. Further, the solenoid valve 728 can also shut off any piping. The pipe 728 c is a pipe for sending hot water in the storage unit 726 to the extraction container 9.

  By switching communication and blocking between the pipe 728b and the pipe 728a, communication and blocking between the storage unit 725 and the storage unit 726 can be switched. By switching communication and blocking between the pipe 728b and the pipe 728c, it is possible to switch between sending and storing hot water in the storage unit 726.

  The solenoid valve 728 blocks the pipe 728b and the pipe 728c when the pipe 728b and the pipe 728a are communicated with each other. Conversely, when the pipe 728b and the pipe 728c are communicated, the pipe 728b and the pipe 728a are blocked. The arrow shown in the electromagnetic valve 728 in the figure indicates the operating state of the electromagnetic valve 728. In the example of FIG. 68, the pipe 728b and the pipe 728c are communicated, and the pipe 728b and the pipe 728a are blocked. Indicates the state.

  In the present embodiment, the electromagnetic valve 728 is a three-way valve, and the switching is performed by one electromagnetic valve 728. However, a configuration in which the pipe 728b is divided into two parts and a valve that switches communication and blocking between one pipe 728b and the pipe 728a and a valve that switches communication and blocking between the other pipe 728b and the pipe 728c is also adopted. Is possible.

  The liquid feeding amount adjusting device 720 includes a drive unit 727. The drive unit 727 is controlled according to the amount of hot water delivered from the storage unit 726 and changes the volume of the storage unit 726. Depending on the size of the coffee cup, the amount of hot water required for a cup varies. The drive unit 727 adjusts the volume of the storage unit 726 so that an appropriate amount of hot water is delivered from the storage unit 726 in accordance with the size of the coffee cup.

  The drive unit 727 of the present embodiment is a mechanism that changes the volume of the reservoir 726 by moving the movable member 727c up and down. The movable member 727c is a piston-like member that is inserted into the space 726A and configured to slide in the vertical direction. The volume of the reservoir 726 changes due to the elevation of the bottom surface 727d.

  The volume of the reservoir 726 is not changed by moving the position of the upper wall body as in the present embodiment, but is changed by moving the position of the lower or side wall body. A configuration can also be employed.

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

  The groove 727e is formed to communicate with an opening 722a that penetrates the partition wall 722 in the thickness direction. The opening 722a is formed at a position above the maximum hot water level of the reservoir 725 (a position of a sensor 731b described later), and is an air communication unit that allows the reservoir 725 and the space 726A to communicate with each other. Air is communicated between the reservoir 725 and the reservoir 726 via the opening 722a and the groove 727e, and the air pressure in these spaces is the same. In addition, when the storage parts 725 and 726 are always at atmospheric pressure, a passage communicating with the atmosphere may be provided individually.

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

  In the present embodiment, a screw mechanism including a screw shaft 727b and a screw hole 727f is used as a moving mechanism for moving the movable member 727c. However, the present invention is not limited to this, and other mechanisms such as a rack-pinion mechanism can be employed. is there.

  The water level sensor 72 c is a measurement unit that measures the water level of hot water in the storage unit 725. The water level sensor 72c includes a hollow cylindrical storage portion 729 that extends vertically, a float 730 provided in the storage portion 729, a lower sensor 731a that detects the float 730, and an upper sensor 731b.

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

  In the case of this embodiment, the storage part 729 is comprised with the member which has transparency, such as glass and an acryl. Thereby, the water level of the hot water of the storage part 729 can be visually recognized from the outside, and as a result, the user can check the water level of the hot water of the storage part 725. Of course, it is also possible to adopt a configuration in which a transmission part is provided on a part of the peripheral wall (721) of the storage part 725 so that the water level can be visually recognized.

  Any float 730 may be used as long as it floats on the hot water in the reservoir 729.

  The sensors 731a and 731b are, for example, optical sensors (photo interrupters), and detect the float 730 from the outside of the storage unit 729. When the sensor 731 a detects the float 730, the electromagnetic valve 72 d is opened and water is supplied to the reservoir 725. That is, the sensor 731a monitors the lower limit of the hot water level of the reservoir 725. The lower limit of the water level is set at a position higher than that of the heater 72a, so that the heater 72a can be prevented from being sprinkled.

  When the float 730 is detected by the sensor 731b, the electromagnetic valve 72d is closed and the supply of water to the reservoir 725 is stopped. That is, the sensor 731b monitors the upper limit of the hot water level of the reservoir 725.

  A configuration equivalent to the water level sensor 72c can also be constructed inside the reservoir 725. However, as in the present embodiment, by constructing the water level sensor 72c outside the storage unit 725, the water level of the storage unit 725 can be easily confirmed from the outside.

  Next, an operation example of the liquid feeding amount adjusting device 720 will be described with reference to FIG. First, the volume of the reservoir 726 is adjusted by the drive unit 727 according to the cup size and the like. State ST61 shows this state. In the example of the figure, the movable member 727c is lowered, and the volume of the storage unit 726 is set to a smaller volume than the example of FIG. The solenoid valve 728 connects the pipe 728b and the pipe 728c, and hot water is not supplied from the storage unit 725 to the storage unit 726.

  When the volume of the reservoir 726 is set, the drive unit 727 is stopped, and the piping 728b and the piping 728a are communicated by the electromagnetic valve 728. The reservoir 725 and the reservoir 726 have the same atmospheric pressure, and the reservoir 726 is on the bottom side of the tank 720a. For this reason, hot water is supplied from the storage unit 725 to the storage unit 726 by the head pressure of the hot water in the storage unit 725. In the case of this embodiment, since it is formed at a position lower than the lowest hot water level of the reservoir 725 (the position of the sensor 731a), there is always a water head difference between the reservoir 725 and the reservoir 726 (reservoir 725 hot water is higher). Therefore, hot water is supplied from the reservoir 725 to the reservoir 726 until the reservoir 726 is full. A state ST62 indicates a state where the storage unit 726 is full. Although hot water also enters the groove 727c, the groove 727c only needs to have a volume sufficient to ensure air communication, and can be made to be a minimal amount.

  In the case of this embodiment, the heater 72a is not provided in the storage part 726, but since the storage part 726 is surrounded by the storage part 725, the heat retaining performance of the stored hot water can be ensured. Note that the volume of the reservoir 726 may be changed by the drive unit 727 in the state ST62.

  Although other methods are possible for supplying hot water from the storage unit 725 to the storage unit 726, in this embodiment, hot water is used with a relatively simple configuration by utilizing the water head difference between the storage unit 725 and the storage unit 726. Can be supplied.

  Next, the hot water stored in the storage unit 726 is sent out. As shown in state ST63, hot water can be sent from the pipe 728c to the extraction container 9 by its own weight or the pressure of the storage unit 726 by connecting the pipe 728b and the pipe 728c with the electromagnetic valve 728. After the hot water supply is started, the operation state of the electromagnetic valve 728 can be sent out in stages by shutting off any piping. For example, for the steaming process (S11 in FIG. 21), it is also possible to perform a process (S12 in FIG. 21) in which hot water is sent out and interrupted, and then the remaining hot water is sent out.

  In any case, the total amount of hot water stored in the storage unit 726 is sent out. The delivery confirmation of the total amount can be performed by the open time of the electromagnetic valve 728 (communication time between the pipe 728b and the pipe 728c). Each time hot water stored in the storage unit 726 is sent out once, the control valve 72d may be opened to supply water corresponding to the amount to the storage unit 725.

  As described above, in this embodiment, the amount of hot water delivered can be adjusted. In general, control of opening and closing a valve based on the detection result using a flow rate sensor is used to adjust the amount of liquid delivered. However, in the case of a high-temperature liquid or a special liquid, a compatible flow sensor may not be commercially available or may be expensive. In this embodiment, the amount of hot water delivered can be adjusted without the need for a flow sensor by adopting a method of adjusting the volume of the reservoir 726.

  Next, another configuration example of the tank 720a will be described. FIG. 71 is a schematic diagram of a liquid feeding amount adjusting device 720 having a different configuration of the tank 720a and a horizontal sectional view of the tank 720a portion.

  In the example of FIG. 68, the storage unit 726 is positioned inside the storage unit 725. However, a configuration in which the storage unit 725 and the storage unit 726 are provided in parallel as in the example of FIG. In addition, in the example of FIG. 68, the horizontal cross-sectional shapes of the storage unit 725, the storage unit 726, and the storage unit 729 are circular, but may be a polygon such as a rectangle as in the example of FIG. Also, other horizontal cross-sectional shapes such as an elliptical shape can be employed. Further, the communication portions 729a and 729b may be configured to communicate the lower end and upper end of the storage portion 729 with the storage portion 725 as in the example of FIG.

  FIG. 72 is also a schematic view of a liquid feeding amount adjusting device 720 having a different tank configuration and a horizontal sectional view of the tank portion. In the example of the same figure, the tank 720b which comprises the storage part 725, and the tank 720c which comprises the storage part 726 are comprised separately. Such a tank configuration can also be employed. In the example of FIG. 72, the storage portion 726 is formed at a position where the bottom surface is lower than the storage portion 725. This makes it easy to supply hot water using the water head difference.

  Next, the structure which supports the storage part 729 between the upper wall 723 and the bottom wall 724 of the tank 720a is also employable. FIG. 73 shows an example. In the example of the figure, a cylindrical member that forms the storage portion 729 is supported between the upper wall 723 and the bottom wall 724, and the peripheral wall 721 that defines the storage portion 725 is also the upper wall 723 and the bottom wall. 724. The communication portions 729a and 729b are formed on the bottom wall 724 and the upper wall 723, respectively. A gasket 729 c is provided between the reservoir 729 and the upper wall 723 and the bottom wall 724.

  In the case of the example in FIG. 73, the storage portion 729 can be supported using the upper wall 723 and the bottom wall 724, and in particular, since the storage portion 729 and the peripheral wall 721 are arranged in parallel, the peripheral wall 721 is used as the storage portion. 729 can also be used as a reinforcing member.

  When the storage part 729 is configured by a glass tube or the like, as shown in a configuration example EX32 in place of the gasket 729c, a storage part 729 is used instead of the gasket 729c in order to prevent an action of a load at a boundary portion between the upper wall 723 and the bottom wall 724. A cover 729d may be provided to cover the upper and lower end portions. The cover 729d may be made of, for example, silicon. In addition, when the storage portion 729 is configured with a glass tube or the like, a mesh sheet may be attached to the peripheral surface to prevent scattering at the time of breakage, and the glass tube is reinforced with a material such as polycarbonate. Also good.

<Ninth embodiment>
Another configuration example of the switching unit 10 will be described. FIG. 74 is a perspective view of the switching unit 10 of the present embodiment. Similar to the first embodiment, the switching unit 10 of the present embodiment also switches the delivery destination of the liquid delivered from the extraction container 9 to either the pouring unit 10c or the waste tank T (not shown in FIG. 74). The same symbols are used for configurations having the same functions.

  An outline of the present embodiment will be described. In the extraction process illustrated in FIG. 21, in S <b> 17, the coffee beverage is sent out with the extraction container 9 set to a predetermined atmospheric pressure (1.7 atmospheric pressure as an example). When the air pressure at this time is set high, the delivery efficiency of the coffee beverage is improved, but the momentum of the coffee beverage poured into the cup C may increase and spill. The switching unit 10 of this embodiment includes a decompression unit 600 and decompresses the coffee beverage poured into the cup C. Thereby, a coffee drink can be poured more gently into a drink container (cup C). Hereinafter, the configuration of the switching unit 10 will be described.

  The switching unit 10 includes a communication unit 10d connected to the communication unit 810a of the operation unit 81C. The coffee beverage, tap water, and ground bean residue in the container body 90 are introduced into the switching unit 10 via the communication portion 810a. The switching valve 10a switches the delivery destination of the coffee beverage or the like introduced into the switching unit 10 to the decompression unit 600 or the pipe 10f. When the coffee beverage is poured into the cup C, the switching valve 10a sets the delivery destination to the decompression unit 100, and when discarding the coffee beverage or residue, the delivery destination is set to the pipe 10f.

  The pipe 10f is connected to an attachment portion 10e to which the waste tank T is attached. A pipe 10g is also connected to the mounting portion 10e. The pipe 10g is a pipe that constitutes another disposal path that does not pass through the switching unit 10, and is used, for example, when discarding water from the water tank 72. Moreover, the drainage part 111a provided in the stage 111 (FIG. 57) may be connected to the piping 10g.

  The decompression unit 600 will be described with reference to FIGS. 74 (A) and 74 (B), FIGS. 75 (A) to 75 (C) and FIGS. 76 (A) and 76 (B). 74 (B) is a perspective view of the decompression unit 600, FIG. 75 (A) is a plan view of the decompression unit 600, FIGS. 75 (B) and 75 (C) are cross-sectional views taken along line VV in FIG. 75 (A), VI FIG. 76A and 76B are perspective views of the lower case 602. FIG.

  The decompression unit 600 is a hollow box (decompression vessel) having a space 600a therein. The decompression unit 600 includes an introduction pipe 604a into which the coffee beverage is introduced via the switching valve 10a and a pouring unit 10c that pours the coffee beverage into the cup C. Before the produced coffee beverage is poured into the cup C, the space 600a The coffee drink is configured to pass through. The volume of the space 600a is, for example, a volume larger than the maximum liquid amount of a cup of coffee drink.

  The pouring part 10 c is formed so as to protrude downward from the bottom of the decompression part 600, and has a delivery port 605 at the lower end thereof. The delivery port 605 communicates with the space 600a and delivers a coffee beverage that passes through the space 600a. The delivery port 605 may constitute a spout, or a nozzle that forms the spout may be connected.

  The introduction pipe 604 is a cylindrical pipe extending in the front-rear direction. One end 604a of the introduction pipe 604 is connected to the switching valve 10a, and the other end thereof introduces a coffee beverage into the space 600a. The introduction port 604b opens into the space 600a. Is configured. The introduction port 604b is formed at a position higher than the delivery port 605, so that the coffee beverage easily flows to the delivery port 605 by its own weight. Further, the introduction port 604b is formed closer to the delivery port 605 than the communication hole 606 in a plan view (at a position in the horizontal direction).

  The decompression unit 600 has a monaca structure in which an upper case 601 constituting the upper half and a lower case 602 constituting the lower half are vertically coupled to form a space 600a.

  The upper case 601 includes a flange portion 601a and a bulging portion 601b that is surrounded by the flange portion 601a and bulges upward, and the bulging portion 601b defines the upper portion of the space 600a. The lower case 602 has a flange portion 602a and a bulging portion 602b bulging downward surrounded by the flange portion 602a, and the bulging portion 602b defines a lower portion of the space 600a.

  The upper case 601 and the lower case 602 are fastened with screws by overlapping the flange portion 601a and the flange portion 602a. A seal member 603 is interposed between the flange portion 601a and the flange portion 602a to seal the space 600a.

  A communication hole 606 that allows the space 600a to communicate with the atmosphere is formed in the wall of the decompression unit 600. When the coffee beverage is introduced into the space 600a in a pressurized state, the air in the space 600a is released from the communication hole 606 to the atmosphere. Thereby, the coffee beverage can be depressurized. In the case of the present embodiment, the communication hole 606 is formed in the upper wall portion 600 b that forms the top of the decompression unit 600 so that the introduction port 604 b is positioned lower than the communication hole 606. By forming the communication hole 606 at a high position in the space 600a, it is possible to prevent the coffee beverage from leaking out of the communication hole 606.

  The space 600a of the present embodiment is a space that is long in the left-right direction, and an introduction port 604b is formed on one end (left end) 600c side in the longitudinal direction, and the delivery port 605 has one end 600c and the other end. In the present embodiment, it is formed at an intermediate portion between the one end portion 600c and the other end portion 600d. When the momentum of the coffee beverage introduced from the introduction port 604b is strong, the coffee beverage passes through the delivery port 605 and flows to the other end 600d side, and then flows back to the delivery port 605. Can be weakened.

  In addition, since the introduction port 604b and the delivery port 605 are formed at positions shifted in the horizontal direction, the section where the coffee beverage flows through the space 600a can be secured longer, and the momentum can be reduced. it can.

  The communication hole 606 is formed in a portion closer to the introduction port 604b than the delivery port 605 in the horizontal direction. With such an arrangement, it is difficult for the coffee beverage to leak from the communication hole 606 with the momentum of the coffee beverage from the introduction port 604d toward the delivery port 605. Moreover, the gas mixed in the coffee beverage can easily escape from the communication hole 606 at an early stage, and can be prevented from being blown out from the delivery port 605. Note that the number and positions of the communication holes 606 are not limited thereto, and a plurality of communication holes 606 may be provided, or the communication holes 606 may be formed at different sites.

  The lower case 602 forms left and right bottom surfaces 610 and 611 and front and rear peripheral surfaces 612 and 613 of the space 600a. Each of these surfaces is an inclined surface inclined toward the delivery port 605 and can prevent the coffee beverage in the space 600a from staying in the space 600a and can easily flow to the delivery port 605.

  The lower case 602 also forms left and right peripheral surfaces 614 and 615 of the space 600a. The peripheral surface 614 is a peripheral surface on the one end portion 600c side, and the peripheral surface 615 is a peripheral surface on the other end portion 600d side.

  The peripheral surface 614 is formed with a notch 614a having a C-shaped cross section formed so as to extend the flow path in the introduction pipe 604 in the front-rear direction, and the end of the notch 614a faces the introduction port 604a. A wall surface 614b is formed. When the momentum of the coffee drink introduced from the introduction port 604b is strong, it can collide with the wall surface 614b and weaken the momentum.

  The lower case 602 is formed with wall bodies 621 and 622 extending in the vertical direction. The wall surface of the wall body 621 is parallel to the left and right vertical direction, and the wall surface of the wall body 622 is parallel to the front and rear vertical direction. In other words, the wall surface of the wall 621 is a surface that intersects the passage direction (front-rear direction) of the passage in the introduction pipe 604, and is a surface that is orthogonal in the present embodiment. The wall surface of the wall body 622 is a surface that does not intersect the passage direction (front-rear direction) of the passage in the introduction pipe 604, and is a parallel surface in this embodiment.

  The end portions of the wall bodies 621 and 622 are continuous, and as a whole, constitutes a column having an L-shaped cross section. The wall bodies 621 and 622 are extended to a position facing the communication hole 606, and the communication hole 606 is surrounded by the wall bodies 621 and 622 in a plan view of the decompression unit 600. In other words, the wall body 621 is positioned on the front side of the communication hole 606, and the wall body 622 is positioned on the right side of the communication hole 606.

  Such wall bodies 621 and 622 serve as a baffle plate that prevents the coffee beverage in the space 600 a from moving toward the communication hole 606, and can prevent the coffee beverage from leaking from the communication hole 606. The wall bodies 621 and 622 extend to a position higher than the introduction port 604b and reach a position having a slight gap with the upper wall portion 600b. In the case of this embodiment, this gap is smaller than the diameter of the inlet 604b. The height from the inlet 604b to the upper ends of the wall bodies 621 and 622 is longer than the diameter of the inlet 604b.

  With such a configuration, even when a large amount of coffee drink is introduced, it is difficult to blow out from the communication hole 606. When the pressure of the coffee beverage flowing into the decompression unit 600 is high, there is a possibility that the space 600ahe mist may be blown out from the introduction port 604b, but by narrowing the gap between the upper ends of the wall bodies 621 and 622 and the upper wall unit 600b. This makes it difficult for soaring drops to come out of the container.

  In the case of the present embodiment, the introduction port 604 b opens in the wall body 621. The coffee beverage that has flowed into the space 600a from the introduction port 604b is prevented from moving to the rear side by the wall body 621, and the coffee beverage immediately after the inflow having the strongest momentum can be prevented from moving toward the communication hole 606. Increasing the diameter of the inlet 604d is effective in reducing the momentum of the coffee beverage that flows in, for example, 10 mm or more and 30 mm or less.

  Next, another configuration example of the decompression unit 600 will be described. FIG. 77 is a plan view of another example lower case 602. In the example of the figure, a plurality of communication holes 606A and 606B are formed in an upper case (not shown). The communication holes 606A and 606B are both in the horizontal direction and closer to the inlet 604b than the outlet 605, so that air can easily escape early.

  The bulging portion 602b has an L-shape, and an imaginary line 633 connecting the introduction port 604b and the delivery port 605 formed in the wall body 621 crosses the flange portion 602a. An upper case (not shown) is provided with a bulging portion having a shape corresponding to the bulging portion 602b. That is, the coffee beverage flows from the introduction port 604b to the delivery port 605 while detouring into an L shape. Thereby, reduction of the momentum of coffee beverage and separation of air can be promoted.

  The bottom surfaces 630, 631, and 632 are inclined downward in the direction indicated by the arrow in the figure, and the bottom surfaces are sequentially inclined downward from the bottom surface 630 → the bottom surface 631 → the bottom surface 632. Thereby, it is possible to facilitate the smooth flow of the coffee beverage from its introduction port 604b to the delivery port 605 by its own weight.

  A gap 621a with the peripheral surface is formed at the right end of the wall body 621, so that even if a coffee drink enters the space 621b on the back side of the wall body 621, the coffee drink does not accumulate there and can escape from the gap 621a. I have to.

  78A is a plan view of still another lower case 602, and FIG. 78B is a cross-sectional view of the decompression unit 600 using the lower case 602 of FIG. 78A. It is sectional drawing which follows the VII-VII line of A).

  In this example, the decompression unit 600 is formed long in the front-rear direction. The wall body 621 is provided not in the lower case 602 but in the upper case 601. In plan view, the introduction port 605b is positioned on a straight line from one end 604a of the introduction tube 604 to the delivery port 605, and the wall body 621 is inclined with respect to this straight line.

  The bottom surface 641 is inclined in one direction downward from the rear to the front, so that the coffee beverage is less likely to accumulate at the peripheral edge of the space 600a. When the height from the inlet 604b to the communication hole 606 is compared with the height from the outlet 605 to the inlet 604b, the former height is higher.

  The bottom surface 641 is inclined in one direction downward from the rear to the front, so that the coffee beverage is less likely to accumulate at the peripheral edge of the space 600a. When the height from the inlet 604b to the communication hole 606 is compared with the height from the outlet 605 to the inlet 604b, the former height is higher. Further, the communication hole 606 may be provided above the delivery port 605. By doing so, since the distance from the introduction port 604b to the communication hole 606 is increased and the distance from the delivery port 605 is also increased, separation of air and coffee beverage is facilitated.
