The drip portion 11 is configured by being held between 30 and the holder receiving portion 50.

  Since the container holder 41 is the same member as the case where the coffee powder accommodated in the pod type container shown in FIG. 4 is used, the description thereof is omitted.

  The sprinkling plate 43 is formed in a disc shape as a whole, and a wall portion 43b is formed on the outer peripheral portion of the upper surface 43a. The upper surface 43a is formed in an annular shape with a predetermined width, and a lower projecting portion 43c projecting downward is formed on an inner portion of the upper surface 43a. A small-diameter upper protrusion 43d is formed in the center of the lower protrusion 43c, a circular concave surface 43e is formed in the center of the upper protrusion 43d, and a plurality of openings 43f are formed in the concave surface 43e. .

  A grip portion 43g extending outward is formed from a part of the upper surface 43a, and the user can easily hold the water spray plate 43 by using the grip portion 43g. A flat surface 43h having a predetermined area is formed on the upper surface side portion of the grip portion 43g. Similar to the flat surface 42e on the upper surface of the grip portion 42d of the pod adapter 42 described in FIG. 4, the flat surface 43h is located near the hinge mechanism 33 of the cover 30 when the cover 30 covers the raw material container 40a. The arranged pressing member presses the flat surface 43h, whereby the adhesion between the lid 30 and the raw material container 40b can be further improved. Further, a knob 43i formed higher than the wall 43d is formed on the wall 43d opposite to the grip 43g of the water spray plate 43, and when the user has the water spray plate 43, the grip In addition to 43 g, the knob portion 43 i can be used as an auxiliary.

  The filter member 44 is a substantially cup-shaped member that increases upward.

  An annular collar portion 44a is formed outward from the upper portion of the filter member 44, and an upward wall portion 44b is formed on the outer periphery of the collar portion 44a. The side surface of the filter member 44 is composed of a columnar member 44c disposed at a predetermined interval and a mesh member 44d disposed between the columnar members 44c. A predetermined amount of coffee powder is placed inside the filter member 44. One cup of coffee can be extracted.

  As an example of the mesh member 44d, a 200th mesh made of stainless steel can be used. As the filter member 44d, a mesh member such as a nylon mesh can be used in addition to the stainless mesh. Further, as a mesh count, a mesh with a predetermined roughness of about 100 to 300 can be used in consideration of a suitable extraction speed of the beverage to be extracted.

  A grip part 44e extending outward from the collar part 44a is formed in a part of the collar part 44a, and a wall part 44b is not formed in the formation part of the grip part 44e, and a notch part 44f is formed.

  Since the inner diameter of the wall portion 44 b is formed slightly larger than the outer diameter of the wall portion 43 b of the water spray plate 43, the water spray plate 43 can be placed on the filter member 44. In addition, the width of the grip 44e of the filter member 44 is slightly smaller than the width of the notch 41f of the container holder 41, and further has a size that can be accommodated inside the back of the grip 43g of the water spray plate 43. Yes. Further, the width of the cutout portion 44 f of the filter member 44 is formed to be slightly larger than the width of the grip portion 43 g of the water spray plate 43. For this reason, the container holder 41, the filter member 44, and the water spray plate 43 can be laminated | stacked in this order in the state which mutually aligned in the rotation direction.

  A pair of position regulating partitions 44g formed higher than the wall portion 44b is formed on the outer side of the flange portion 44a of the filter member 44. Similarly to the position regulating partition 42h of the pod adapter 42, the position regulating partition 44g is fitted with a positioning groove formed on the inner surface side of the lid 30 when the lid 30 covers the raw material container 40b. The positional relationship between the lid 30 and the raw material container 40b can be more accurately regulated.

  In the coffee maker 100 according to the present embodiment, when a pod is used as the extraction raw material, the pod adapter 42 shown in FIG. 4 is placed on the container holder 41 to constitute the raw material container 40a and disposed in the drip portion 11. In the case of directly using coffee powder as the extraction raw material, the water spray plate 43 and the filter member 44 shown in FIG. 5 are stacked and placed on the container holder 41 to form the raw material container 40b, and the drip portion 11 By arranging, any of the extraction raw materials can be used to easily extract coffee similarly. At this time, in the coffee maker 100 according to the present embodiment, the user can use the raw material container 40 in a state in which the coffee powder is accommodated therein, regardless of whether the pod is used as the extraction raw material or the coffee powder is directly used. (40a, 40b) can be handled integrally using the gripping portion 41d of the container holder 41.

  FIG. 6 is a perspective view showing the coffee maker with the raw material container removed.

  In the coffee maker 100 of the present embodiment, the lid body 30 of the drip portion 11 arranged on the narrow side surface (one side surface) side of the main body portion 1 is rotatable by the hinge mechanism 33, as shown in FIG. In addition, the lid 30 can shift from a closed state covering the upper portion of the raw material container 40 of the drip portion 11 to an open state opened by a predetermined angle (about 50 degrees as an example) in a direction retreating from one side surface. Yes.

  In the drip portion 11, a holder receiving portion 50 to which the raw material container 40 is attached is formed on a disc-shaped bottom surface 51, a side surface 52 formed as an inclined surface that increases as it goes upward, and an upper end portion of the side surface 52. The ring-shaped flange portion 53 that extends outward and the wall portion 54 that extends upward from the outer peripheral portion of the flange portion 53 are configured.

  An opening 55 is formed at the center of the bottom surface 51 of the holder receiving portion 50 concentrically with the bottom surface 51. As shown in FIG. 6, the side surface 52, the collar portion 53, and the wall portion 54 of the holder receiving portion 50 are all formed only on the main body portion 1 side, and the side surface 52 and the collar portion 53 of the holder receiving portion 50 are formed. Each of the wall portions 54 is a cutting line along a center line passing through the center of the bottom surface 51, and has a shape in which about half located on one side of the main body portion 1 is cut and opened.

  As described in detail with reference to FIGS. 4 and 5 as the raw material container in the coffee maker of the present embodiment, the raw material container 40a in the case of using the pod and the raw material container 40b in the case of using the coffee powder as they are respectively configured. Although the members to be used are different, all of them are placed on the same container holder 41 and configured to have the same external shape when assembled as the raw material container 40.

  Moreover, the container holder 41 in the coffee maker 100 of the present embodiment is formed in a substantially cylindrical shape having a side surface that gradually decreases in diameter toward the bottom surface side. On the opposite side of the gripping portion 41d to be gripped, only the gripping portions 42d and 43g are formed as members extending in a flat plate shape from the side surface. For this reason, the user facing the narrow side surface (the left front side surface in FIG. 6), which is one side surface of the main body unit 1, tried to place the raw material container 40 on the holder holding unit 50. In this case, there is no part that interferes with the holder holding part 50, and the user can position the raw material container 40 on the holder receiving part 50 so as to push it straight.

  On the other hand, a cylindrical projection 41i is formed on the bottom surface 41g of the container holder 41 so as to surround a through hole 41j formed in the bottom surface 41g (see FIG. 7). The size fits into the opening 55 formed in the bottom surface 51 of the portion 50. For this reason, the user lifts the raw material container 40 a little on the holder receiving part 50 by slightly lifting the raw material container 40 so that the cylindrical protrusion 41i fits into the opening 55 beyond the bottom surface 51 of the holder receiving part 50. Can be placed in the correct position. Therefore, in the coffee maker 100 according to the present embodiment, it is not necessary to completely open the lid body 30 that covers the upper portion of the raw material container 40 when placing the raw material container on the drip portion 11, and as shown in FIG. If the rotation of about 50 degrees is performed as an example, the raw material container 40 can be placed at a predetermined position of the drip portion 11 from the side of the main body 1.

  On the other hand, as described above, the bottom surface 51 of the holder receiving portion 50 is formed in an annular shape, and the cylindrical protrusion 41 i on the bottom surface of the container holder 41 is fitted into the opening 55 of the bottom surface 51. Yes. Further, flat surfaces 42e and 43h are respectively formed on the upper surfaces of the gripping portions 42d and 43g extending toward the inner side of the main body 1, which is the back side of the raw material container 40 attached to the drip portion 11. Is formed. Since the flat surfaces 42e and 43h are pressed by the holding rib 39 (see FIG. 6) which is a pressing member formed in the vicinity of the hinge mechanism 33 of the lid body 30 when the lid body 30 is closed, the lid body If 30 is locked in a state of covering the raw material container 40, the raw material container 40 can be firmly held in the drip portion 11, and will not come off to the near side. For this reason, in the coffee maker 100 of this embodiment, the mounting of the raw material container 40 inside the main body is much easier than in the conventional coffee maker, and the raw material container 40 can be detached from the side of the main body. Therefore, there is no inconvenience that a low position must be selected as a place for placing the coffee maker 100.

  Next, the structure which ensures safety | security when the raw material container in which the extraction raw material was accommodated in the coffee maker 100 of this embodiment is not mounted correctly is demonstrated.

  FIG. 7 is a perspective view of the raw material container disposed in the drip portion of the coffee maker according to the present embodiment as viewed from the obliquely lower side. Fig.7 (a) shows the shape of the raw material container in the case of extracting coffee using a pod. Moreover, FIG.7 (b) has shown the shape of the raw material container in the case of using the ground coffee powder as it is.

  As shown in FIG. 7A, in the raw material container 40a in the case where the pod is used as the extraction raw material, the pod holding portion 42 is stacked on the holder member 41, and is opposite to the holding portion 41d of the holder member 41. On the lower surface of the distal end portion of the grip portion 42e of the pod holding portion 42 that protrudes to the protrusion portion 45, a protruding portion 45 as a detection member that protrudes downward in a state where the raw material container 40a is disposed on the drip portion 11 of the main body portion 1. Is formed.

  Further, as shown in FIG. 7B, in the raw material container 40b when the ground coffee powder is used as it is as an extraction raw material, the filter member 44 and the water spray plate 43 are sequentially stacked on the holder member 41. The raw material container 40b is also placed on the lower side of the drip part 11 of the main body 1 on the lower surface of the tip part of the gripping part 43g of the water spray plate 43 protruding to the opposite side of the gripping part 41d of the holder member 41. A protruding portion 45 is formed as a detection member protruding toward the surface.

  As described above, in the coffee maker 100 of the present embodiment, the raw material container 40 (40a, 40b) is provided in the drip portion 11 in both cases where a pod is used as an extraction raw material and where ground coffee powder is used directly. In the state in which is placed, a protruding portion 45 protruding downward is formed at the tip position of the raw material container 40 that is positioned most inside the main body portion 1.

  FIG. 8 is an enlarged cross-sectional view of a main part for explaining the cross-sectional configuration of the drip part in the coffee maker of the present embodiment. In FIG. 8, the raw material container in the case of using the coffee accommodated in the pod as an extraction raw material as a raw material container which comprises a drip part is shown.

  As shown in FIG. 8, in the coffee maker 100 of the present embodiment, in the raw material container 40 a placed on the drip portion 11 of the main body 1, the tip of the grip portion 42 d of the pot holding portion 42 is directed downward. A protruding projection 45 is formed, and this projection 45 reaches the vicinity of the hinge mechanism 33 that is the base portion of the lid 30 that covers the raw material container 40a.

  On the other hand, in the drip portion 11 of the main body portion 1, the raw material container 40 a is placed between the lid body 30 and the holder support portion 50, and the switch member is placed at a position corresponding to the arrangement position of the protrusion 45. 70 is arranged. The switch member 70 is formed of a protrusion switch 71 protruding upward and a switch body 72 capable of detecting whether the protrusion switch 71 is pressed. When the raw material container 40a is correctly disposed at a predetermined position of the drip portion 11, the lid body 30 is locked and pressed from the lid body 30 to the holder receiving portion 50 side with a predetermined pressing force, the projection 45 Since the protrusion switch 71 is pushed down, the state in which the raw material container 40a is correctly placed and fixed can be detected by the switch member 70.

  The switch member 70 is electrically connected to a control circuit (not shown), and transmits an electrical signal that can determine whether or not the protrusion switch 71 is pressed to the control circuit. As a result, the control circuit operates the coffee maker 100 based on the electrical signal from the switch member 70 only when the raw material container 40a is correctly placed at a predetermined position, and supplies steam and hot water to the raw material container 40a. The coffee extraction process can be performed by supplying the coffee powder contained in the pod.

  In the coffee maker 100 of the present embodiment, the coffee extraction process is started only when it is detected that the raw material container 40 has been correctly placed, so that the user forgets to place the raw material container 40, or When the raw material container 40 formed by laminating a plurality of members is not properly configured, the lid 30 is not completely locked and the supply path for steam and hot water is sealed with respect to the external space. Even when the user tries to start the coffee extraction process by operating the operation button 15 in the absence of water, the boiler unit 24 is activated to prevent the water from being warmed and generating steam and hot water. it can. As a result, in the coffee maker 100 of the present embodiment, it is possible to avoid a situation in which generated steam and hot water jump out undesirably when the drip portion is not placed in the correct state.

  In addition, in the coffee maker 100 of this embodiment, after mounting the extraction raw material part in the drip part 11, it forms in the engaging pin 38 of the cover body 30, and the upper side surface of the container holder 41 by rotating the cover body 30. The first engaging portion 41h and the second engaging portion 56 formed in the upper portion of the side surface of the container receiving portion 50 are engaged with each other, so that the lid body 30 is connected to the raw material container 40 and the container receiving portion. 50 is configured to be integrally locked with respect to 50. Further, the lid 30 is not locked with respect to the raw material container 40 and the container receiving part 50 because the engaging pin 38, the first engaging part 41h, and the second engaging part 56 are not engaged. In a state, it is urged | biased using elastic members, such as a spring, so that the cover body 30 may rotate to the open direction centering on the hinge mechanism 33. As shown in FIG. Therefore, in the coffee maker 100 of the present embodiment, when the lock is released by rotating the lid 30, the lid 30 is shown in the direction in which the tip portion is immediately opened, that is, as an arrow A in FIG. 2. It turns toward the back side of the main body 1 that is the direction.

  At this time, in the coffee maker 100 of the present embodiment, the lid body 30 is opened at two-stage angles, that is, a small first angle and a larger second angle. The configuration will be specifically described below.

  FIG. 9 is a perspective view showing a state where the lid is opened at a small first angle as a predetermined angle in the coffee maker of the present embodiment. The small 1st angle in the coffee maker of this embodiment is 7 degrees as an example.

  FIG. 10 is a perspective view showing a state in which the lid is opened at a large second angle, which is the maximum rotation angle at which the top of the raw material container is opened, in the coffee maker of the present embodiment. The big 2nd angle in the coffee maker of this embodiment is 50 degrees as an example.

  FIG. 11 is an enlarged cross-sectional view of a main part for explaining the internal structure of the drip part in the coffee maker of the present embodiment. FIG. 11A shows a state in which the lid is opened at a small first angle, that is, the same state as that shown in the perspective view of FIG. FIG. 11B shows a state where the lid is opened at a larger second angle, that is, the same state as the state shown in the perspective view of FIG.

  In the coffee maker 100 of the present embodiment, as described above, when the locked state is released by the elastic member (not shown) provided in the hinge mechanism 33, the lid body 30 automatically moves in the opening direction. At this time, as shown in FIGS. 11 (a) and 11 (b), the rear end 39 of the lid 30 located further rearward than the hinge mechanism 33 of the lid 30 is located inside the main body 1. In order to receive the interference force by coming into contact with the arranged stopper 73, the lid 30 is temporarily stopped in a state where it is opened by 7 degrees which is the first angle.

  In the coffee maker 100 of the present embodiment, the protrusion switch 71 of the switch member 70 that detects that the raw material container 40 is correctly placed and the lid 30 is firmly closed is 40, the protrusion 45 formed on the tip end portion on the inner side of the main end 1 is pressed. However, when the lid 30 is opened at a first angle of 7 degrees, the protrusion 45 is pressed against the protrusion switch 71. Pressure is reduced. By setting so that the switch member 70 can detect the reduction of the pressing force to the protrusion switch 71, the switch member 70 can detect that the cover 30 is unlocked. It becomes.

  For this reason, in the coffee maker 100 of the present embodiment, even when the opening angle of the lid 30 is a small first angle, for example, it is detected that the locked state has been released, and the control circuit immediately extracts the coffee. Can be set to stop. For this reason, it is possible to avoid an unexpected situation in which steam or high-temperature hot water jumps out of the discharge unit 35 and scatters around the coffee maker 100.

  When the lid 30 is unlocked during the operation of the coffee maker 100 and the switch member 70 detects that the lid 30 has been opened, the control circuit detects the warning sound or the lamp is lit. It can be set to notify the user of the occurrence of an abnormality.

  In addition, when the switch member 70 detects that the lid 30 has been opened and the control circuit stops the drip operation based on the detection result, the control circuit performs a very short time (for example, 3 seconds at this time). The water supply capacity of the water supply pump 23 is 3.3 mL / second, and as an example, about 10 mL) of water can be controlled to be fed into the boiler unit 24.

  When the water in the boiler unit 24 is warmed and becomes high temperature, in order to stop the operation of the boiler unit 24, the control circuit immediately turns off the power of the boiler unit 24 and stops further heating. Even in this case, when the temperature of the water accumulated in the boiler section 24 is high, it cannot be expected that the discharge of steam or hot water from the discharge port 35 immediately stops. For this reason, in the coffee maker 100 of the present embodiment, when the drip process is stopped by detecting that the lid body 30 is opened, water is supplied into the boiler unit 24 for a short time, so that the boiler unit The temperature of the water in 24 can be forcibly cooled, and it is possible to more reliably avoid undesirably protruding high-temperature steam or hot water.

  Note that if water is supplied to the boiler unit 24 with the lid 30 opened even slightly, the hot water in the boiler unit 24 and the hot water supply pipe 25 may be ejected from the discharge port 35 in a form pushed out by the added water. There is. However, the coffee maker 100 of the present embodiment includes the switch member 70 that can immediately detect that the lid 30 is unlocked, and the lid 30 is opened at a small first angle. Therefore, even when hot water is discharged from the discharge port 35, most of the direction goes to the facing raw material container 40. For this reason, even if the control circuit dares to control the operation so that the hot water protrudes, a situation in which a large amount of hot water is scattered outside the drip portion 11 of the coffee maker 100 can be avoided. The pop-out direction can be controlled in a state of facing downward.

  In the coffee maker 100 of the present embodiment, by applying an external force in a direction in which the lid 30 is further opened from the state where the lid 30 is opened at the first angle, the tip of the rear end portion 39 of the lid 30 is the stopper member 73. It moves so as to slide on the upper surface of the stopper, and the stopper once comes off. Thereafter, as shown in FIG. 11B, the rear end portion 39 of the lid body 30 comes into contact with the base portion of the hinge mechanism 33 and stops while entering the lower side of the hinge mechanism 33.

  By doing in this way, the lid 30 can be opened at a large second angle as the maximum rotation angle that opens the lid 30, and the lid 30 is opened more than the second angle. In addition, the lid 30 cannot return to the opened state at the first angle unless a predetermined force is applied. For this reason, in the coffee maker 100 of this embodiment, the cover body 30 can be maintained in the open state at the second angle.

  After the extraction of the coffee is completed, the user holds the raw material container 40 with the holding portion 41d of the holder member 41 and holds the raw material container 40 in the holder receiving portion 50 when the lid 30 is maintained in the opened state at the second angle. It can be easily removed from the predetermined position above.

  In addition, when newly extracting coffee, the user places the raw material container 40 in a state in which a pod or coffee powder is set again on the holder receiving portion 50, and performs a predetermined direction in which the lid 30 is closed. The cover body 30 is locked by being rotated by rotating the outer peripheral portion 31 of the lid body 30 to be closed. At this time, when the raw material container 40 is correctly configured and mounted in the correct position, the projection switch 71 of the switch member 70 is pushed down, so that the control circuit has correctly placed the raw material container 40. And a predetermined drip process can be started.

  In the above embodiment, the rotation angle of the lid body 30 is exemplified as 7 degrees as a small first angle in a state where the lid body 30 is unlocked. The first angle is not limited to 7 degrees, and is within a range in which it is possible to detect that the lid 30 is unlocked by the switch member 70 or the like that is a detection mechanism, and high temperature hot water or The angle at which the steam is less likely to splash outside can be set as a predetermined angle of, for example, about 3 degrees to 15 degrees.

  Further, the second angle at which the lid 30 opens greatly is not limited to 50 degrees exemplified. The second angle only needs to be an angle at which the user can easily take out the raw material container 40, and can be set as a predetermined angle of about 30 degrees to 90 degrees, for example. Although the second angle for opening the lid 30 can be 90 degrees or more, the lid 30 opens 90 ° C. or more in consideration of convenience when the user closes the lid. The significance of setting in this way is not great.

  As described above, in the coffee maker according to the present embodiment, the lid body that covers the upper portion of the raw material container in which the extracted raw material is stored can be opened and closed, and includes a hinge mechanism so that the upper portion of the raw material container is covered. The lid body can be rotated at a predetermined angle with respect to the open state in which the upper portion of the raw material container is opened, and the lid body can be stopped at a predetermined angle smaller than the maximum rotation angle at which the raw material container is opened. For this reason, in the coffee maker of this embodiment, even when the lid is unlocked, the lid does not open to the open state at once, and high-temperature steam or hot water for extracting coffee is not used. , Can be effectively prevented from scattering outside.

  In the above-described embodiment, the example in which the biasing means for biasing the lid body in the direction of transition from the closed state to the open state is provided, but the biasing means for biasing the lid body to the open state side is shown. Is not an essential component in the coffee maker of this embodiment.

  Also, in the above embodiment, as a configuration that enables both pod type coffee and coffee powder, different members can be used to hold different extraction raw materials while maintaining the same outer shape of the raw material container. In this example, the detection member that detects that the lid is in a closed state can also detect that the raw material containers are correctly stacked. However, in the coffee maker of this embodiment, it is not essential that different extraction raw materials can be used. In this case, it is not necessary that the detection member for detecting that the lid is in the closed state can simultaneously detect that the raw material container is correctly configured.

  Moreover, the specific shape of the raw material containers 40a and 40b illustrated in the said detail is only an illustration. Various types that can be placed between the lid 30 and the holder receiving portion 50 to hold the extraction raw material inside and extract the beverage using hot water supplied from the discharge port 35 formed in the lid 30. A raw material container 40 in the form can be used. In addition, when using the raw material supplied with a different form as extraction raw materials like the coffee maker 100 of this embodiment, the raw material container 40 is made into the assembly of several parts, and a part or all members can be replaced | exchanged. It is preferable to assemble and design so that the outer shape required as a raw material container and the shape required as a raw material holding part for holding the raw material disposed inside can be compatible.

  As shown in FIGS. 4 and 5, in the coffee maker 100 of the present embodiment, any raw material can be obtained by making the outer shape of the raw material container 40 (40a, 40b) substantially the same when different raw materials are used. Even when the container 40 is used, it is arranged and fixed in the same state between the lid 30 and the holder receiving portion 50. In addition, an indicator part such as a protrusion or a recess is provided in an outer shape part such as an upper part or a side part of the raw material container 40, and the shape of the indicator part is read by the detection means provided in the main body part 1, so that it is mounted on the drip part 11. It is possible to determine the type of the raw material container 40 placed. In this case, the control unit can automatically execute different extraction steps depending on each raw material according to the determination result.

  Moreover, although the said embodiment demonstrated the example of the structure which can place a raw material container directly in a container holding part from the side with respect to one side of the coffee maker which is a drink extraction apparatus, to the container holding part of a raw material container This placement is not limited to the one from the side, and not directly, but for example, a door-shaped protective member that covers the container housing portion is opened to place the raw material container.

  Moreover, in the said embodiment, although the coffee maker which can respond to both the case where a pot member was used as an extraction raw material, and the case where coffee powder was directly used, the drink extraction device of this indication was used as a coffee maker. Even when it is used, it can be a coffee maker that does not correspond to the coffee powder contained in the pod.

  Furthermore, in the said embodiment, although the coffee maker which extracts regular coffee from coffee powder was illustrated and demonstrated as a drink extraction apparatus, as a drink extraction apparatus disclosed by this application, tea leaves, such as black tea, Japanese tea, and oolong tea, are used. It can also be realized as a beverage extraction device for extracting so-called tea. Various beverages are also extracted, such as those that extract beverages using cocoa and other powders, those that extract miso soup using paste-like components such as miso, and those that extract various soups and soups It is possible to realize a beverage extraction device.

  Furthermore, the volume of the beverage that can be extracted is not limited to that for extracting a full beverage, and can be realized as a beverage extraction device that can extract a plurality of beverages up to several cups.

  In addition, in the beverage extraction device according to the present disclosure, the method of feeding water from the water storage tank to the heating unit is not limited to the configuration including the illustrated water pump, but by the action of heated water or generated steam. It can also be realized as a system for supplying hot water to the drip section. However, in this case, it is not possible to employ a safety mechanism that forcibly injects a small amount of water into the boiler section when it is detected that the lid is slightly opened as described in the above embodiment.

  In the above, as a beverage extraction device disclosed in the present application, it is an essential requirement that the lid body rotates in two stages. However, as a beverage extraction configuration of the present disclosure, it is an essential requirement that a detection mechanism for detecting that the above-described raw material container is correctly placed is provided, and that the lid body rotates in two stages. As a non-essential configuration, a configuration shown as [Appendix 1] below can be assumed.

  In this case, the lid opening / closing mechanism is not limited to the hinge mechanism that allows the lid body to be rotated, and the lid body can be completely removed when the lock is released. it can. Further, even when the lid body is rotatable, the rotation direction is not limited to the one that rotates to the near side and the rear side with respect to the upper surface of the main body as exemplified above, but the upper surface of the main body. Various forms such as one that can be rotated in the plane direction (horizontal direction) can be adopted.
