That is, the portion of the power line 18 and the connector 19 exposed to the outside can be minimized. Alternatively, the power line 18 and/or the connector 19 may extend along the support leg 20 and enter the inside of the extraction unit 30. At this time, the portion of the power line 18 and/or the connector 19 passing through the support leg 20 may not be exposed to the outside.

In order to maintain the temperature of water passing through the connection pipe 19, an insulating layer (not shown) may be formed around the connection pipe 19. The connector 19 may have a predetermined length and flexibility to absorb changes in the distance between the base 10 and the extraction unit 30. The insulating layer may be made up of multiple layers as long as it does not impair the ductility of the connecting pipe 19.

A support leg 20 may be installed on the base top plate 14. The support leg 20 may serve to support the extraction unit 30. The support leg 20 can produce movement of the extraction unit 30. The support leg 20 can adjust the height of the extraction unit 30. The support leg 20 can adjust the installation state of the extraction unit 30, for example, the inclination.

Figure 3 shows a state in which the height of the extractor 30 is changed by the support leg 20. In Figure 3 (a), the extraction unit 30 is shown adjacent to the base 10, and in Figure 3 (b), the extraction unit 30 is relatively distant from the base 10. In other words, it is shown in a relatively elevated position.

In the illustrated embodiment, three support legs 20 are used. The three support legs 20 may be arranged at predetermined angular intervals along the circumference of the extraction unit 30. For example, they may be arranged at equal angular intervals from each other. The number of support legs 20 may vary depending on the size of the extraction unit 30 and the operation type of the extraction unit 30.

The support leg 20 may include a support link 22 and a connection link 24. One side of the support leg 20 may be connected to the base 10 and the other side may be connected to the extraction unit 30 through the connecting link 24. The support link 22 and the connection link 24 are connected to each other so that they can rotate relative to each other through a link pin 221 (see FIG. 7). One side of the connecting link 24 is connected to the support link 22 and the other side is connected to the extraction unit 30, and can be relatively rotatably connected to the connection frame 26 inside the extraction unit 30. there is.

The connection frame 26 is generally roughly ring-shaped. The connection frame 26 may be formed into a ring shape by combining a plurality of divided frame bodies 260 with each other. In this embodiment, as shown in FIG. 8, three pieces of frame body 260 are combined to form a ring-shaped connecting frame 26. The connection frame 26 may have a fixing boss 261 for fixing to the frame 31, which will be described below. A plurality of the fixing bosses 261 are provided on the connection frame 26, so that the entire ring-shaped connection frame 26 can be firmly fixed to the frame 31.

The connection frame 26 may have a leg connection portion 263. Each support leg 20 may be connected to the leg connection portion 263 so as to be relatively rotatable. More precisely, the connecting link 24 and the leg driving unit 28, which will be described below, can be simultaneously connected to the leg connecting portion 263 to enable relative rotation. The leg connection portion 263 is concave from the outside to the inside of the ring-shaped connection frame 26.

First rotation center pins 265 protrude from both sides of the leg connection portion 263 to face each other. The first rotation center pin 265 may be the rotation center of the connection link 24 and the leg driving unit 28. There may be a second rotation center pin 267 concentric with the first rotation center pin 265 (see FIGS. 8 and 14). The second rotation center pin 267 is a leg drive unit to be described below. It can be the center of rotation of (28).

The frame body 260 is coupled to each other at one end of the leg connection portion 263. The first rotation center pins 265 are located in separate frame bodies 260, and when these frame bodies 260 are combined, the first rotation center pins 265 face each other. If the frame body 260 is formed by dividing the frame body 260 into pieces equal to the number of support legs 20, the frame body 260 and the support legs 20 can be sequentially combined when assembling the entire device. That is, one frame body 260 is installed on the frame 31, the support leg 20 and the leg driving unit 28 are assembled, and then the frame body 260 is assembled. And when the last frame body 260 and the remaining two support legs 20 and the leg driving unit 28 are assembled simultaneously, the connection frame 26, the support leg 20, and the leg driving unit 28 are assembled. This can be made easy.

A tilt sensor 269 may be installed on one side of the connection frame 26. The tilt sensor 269 can detect the tilt of the connection frame 26, that is, the tilt of the extraction unit 30.

On the opposite side of the support link 22 connected to the connection link 24, there may be a joint 27 supported on the base 10. The support link 22 can be rotated by a predetermined angle with respect to the base 10 by the joint 27. The joint 27 can be viewed as a type of universal joint. The joint 27 has a socket base 270. The socket base 270 may be fixed to the base top plate 14. On the socket base 270, there may be a socket 272 with a predetermined space formed therein. A ball 274 may be located in the space inside the socket 272. The diameter of the ball 274 may be larger than the width of the entrance to the space formed in the socket 272. The ball 274 can be rotated in various directions within the socket 272. There is a connecting bar 276 integral with the ball 275. The connecting bar 276 is connected to the support link 22. Here, the rotation trajectory of the connecting bar 276 can be determined by the shape of the inlet of the socket 272. In the illustrated embodiment, the entrance of the socket 272 is shaped like a long slot in one direction, so that the connecting bar 276 can reciprocate in the longitudinal direction of the slot.

According to this configuration, the support link 22 can be operated to be upright or inclined at a predetermined angle with respect to the base 10 by the joint 27. Of course, the support link 22 can be operated in more diverse ways by varying the shape of the inlet of the socket 272.

Adjusting the angle at which the support link 22 and the connection link 24 constituting the support leg 20 are connected can be performed by the leg driving unit 28. One side of the leg driving unit 28 is relatively rotatably connected to the support link 22 by a link pin 222 (see FIG. 7), and the other side is connected to the connection link 24 and the connection frame 26. It is connected so that it can be rotated relative to. Here, the length of the leg driving unit 28 can be varied so that the side connected to the support link 22 and the side connected to the connection link 24 are closer or farther away from each other. As the length of the leg driving unit 28 changes in this way, the connection angle between the support link 22 and the connection link 24 changes. As the connection angle between the support link 22 and the connection link 24 changes, the position of the connection frame 26 is moved, and the connection frame 26 is connected to the frame 31 of the extraction unit 30. Since it is connected to , the position of the extraction unit 30 can be moved.

As can be seen in FIG. 4, in the illustrated embodiment, there are three support legs 20. If the lengths of the leg driving units 28 of these support legs 20 are equally long and short, each The connection angle of the support link 22 and the connection link 24 changes to be the same, and accordingly, the connection frame 26 can be lifted and lowered equally as a whole.

The configuration of the leg driving unit 28 will be examined with reference to FIGS. 9 to 13. As described above, the leg drive unit 28 has a variable length and changes the connection angle between the support link 22 and the connection link 24 to move the connection frame 26.

Accordingly, the leg driving unit 28 may be of any configuration as long as the relative positions of both ends are different and the length is variable. For example, as another example of the leg driving unit 28, a configuration in which the piston rod moves in and out of the cylinder as the piston in the cylinder moves may be used. Alternatively, a configuration that utilizes the linear motion of the rack gear by interlocking between the rack gear and the pinion gear may be used.

Looking at the configuration of the leg driving unit 28 used in the illustrated embodiment, there is a first driving source 280. The first driving source 280 may provide driving force to vary the length of the support leg 20. The first drive source 280 has a rotation shaft 280' that provides rotational force to the outside. The rotation axis 280' extends outward from the first drive source 280. A lead screw 281 may be connected to the rotation axis 280'. The lead screw 281 may rotate together with the rotation shaft 280'.

The first driving source 280 may be installed on the bracket 282. The bracket 282 is for fixing the first driving source 280. The rotation axis 280' passes through the bracket 282. There may be a fixing frame 283 to which the bracket 282 is fixed. The fixing frame 283 is separate from the bracket 282 and is coupled to each other during assembly. The rotating shaft 280' passes through the fixed frame 283. Accordingly, the fixing frame 283 and the bracket 282 are installed on the connection frame 26 in a coupled state, thereby enabling the first drive source 280 to be installed on the connection frame 26.

The fixed frame 283 is a structure for mounting the first driving source 280, and is located on the side of the lead screw 281 rotated by the first driving source 280. That is, the lead screw 281 rotated by the first drive source 280 penetrates the fixed frame 283 and the bracket 282. Therefore, since the configuration for mounting the first driving source 280 and the configuration operating by the first driving source 280 are in the same space, the space opposite to the space centered on the first driving source 280 can be freely used. You can.

The lead screw 281 may rotate together with the rotation shaft 280'. There may be an inner member 285 surrounding the lead screw 281. The inner member 285 has a cylindrical shape, and the lead screw 281 can be located inside. The outer diameter of the lead screw 281 may be equal to or slightly smaller than the inner diameter of the inner member 285. There may be a connecting ring 286 on one side of the inner member 285. The connecting ring 286 may be connected to one side of the support link 22 so as to be relatively rotatable. The connecting ring 286 may be relatively rotatably connected to the connecting bar 276 of the joint 27 on the support link 22.

There may be an outer member 287 surrounding the inner member 285. The inner member 285 and the outer member 287 may be moved relative to each other in the longitudinal direction. Accordingly, based on the inner member 285, the outer member 287 moves relatively so that the entire length of the leg driving unit 28 can be varied.

In order to perform this operation, there is an interlocking block 288 that is coupled to the inner member 275 and interlocks with the lead screw 281. On the inner surface of the interlocking block 288, there is a threaded portion interlocked with the threaded portion of the lead screw 281. The interlocking block 288 is coupled to the inner member 285 and may not be rotated or moved. For this purpose, a connection key 288' may protrude from the interlocking block 288, and a connection key groove 285' may be provided on the inner member 285. The connection key 288' and the connection key home 285' may be located in opposite positions. For example, a connection key groove is formed in the interlocking block 288 and the connection key is formed in the inner member 285.

Therefore, when the lead screw 281 is rotated by the first driving source 280, the lead screw 261 rotates with respect to the interlocking block 288, and the interlocking block 288 moves with respect to the inner member 285. Since it is fixed so as not to rotate, the lead screw 261 can move in the longitudinal direction with respect to the interlocking block 288. Movement of the lead screw 261 may produce movement of the first drive source 280 through the rotation axis 280' to which the lead screw 261 is coupled. Movement of the first driving source 280 can cause movement of the bracket 282, the fixed frame 283, and the outer member 287 connected to the fixed frame 283. Movement of the first driving source 280 and the fixed frame 283 may cause the connection frame 26 to move.

There may be an extraction unit 30 supported by the support leg 20. Within the extraction unit 30, a beverage can be extracted by injecting water into the capsule 1. A frame 31, a housing 32, and a cover 34 may form the exterior and framework of the extraction unit 30.

The frame 31 may be made in a circular shape. Components to be described below may be mounted on the frame 31. A housing 32 may be mounted on the lower part of the frame 31. The housing 32 may be approximately cylindrical. Inside the housing 32, there may be a configuration through which the extracted beverage is delivered.

There is a cover 34 on the frame 31 opposite to the housing 32. The cover 34 can be raised and lowered relative to the frame 31 . In the illustrated embodiment, the housing 32 and the cover 34 have a cylindrical shape. However, the housing 32 and the cover 34 may have various shapes, such as a polygonal pillar shape.

First and second discharge pipes 57 and 57', which will be described below, may be located inside the housing 32. The housing 32 is mounted on the frame 31, and the connection frame 26 fixed to the frame 31 is supported by the support leg 20, so that the housing 32 is substantially It can be supported by the support leg 20.

The cover 34 is seated on the frame 31 together with the parts therein, and can be separated from the frame 31 by a predetermined distance by driving the second driving source 78. The cover 34 may be moved upward relative to the frame 31 based on the drawing. When the cover 34 moves upward, the capsule sheet 54, which will be described below, is exposed and the capsule 1 can be placed in the capsule seating space 540.

The cover 34 may include a cylindrical cover side wall 340 penetrating upward and downward and a cover top plate 342 forming an upper part of the cover side wall 340. The cover side wall 340 and the cover top plate 342 are integrated. However, the cover side wall 340 and the cover top plate 342 may be made separately and combined. There may be a window 344 on one side of the cover side wall 340. The window 344 may be made of a transparent material so that the inside can be seen from the outside.

There may be a cover boss 346 inside the cover 34, more precisely, on the inside ceiling. The cover boss 346 fixes the fixing plate 36, which will be described below. The cover top plate 342 may have a touch sensor 348. The touch sensor 348 detects when the user touches the finger or the like. The touch sensor 348 may be located in various locations other than the cover top plate 342. The touch sensor 348 can be used by a user to input a signal that drives the cover 34.

A fixing plate 36 may be installed inside the cover 34. The fixing plate 36 may have a shape corresponding to the cross-sectional shape of the cover side wall 340 of the cover 34. In the illustrated embodiment, the fixing plate 36 has a disk shape. The fixing plate 36 may have a fixing boss 360 coupled to the cover boss 346. The number of fixed bosses 360 may correspond to positions corresponding to the cover boss 346.

There may be a moving guide 38 extending from one side of the fixing plate 36. The moving guide 38 can be moved by being guided by the fixed guide 58, which will be described below. The moving guide 38 can be lifted and lowered inside the fixed guide 58. A component for lifting and lowering the cover 34 may be located in the space formed inside the moving guide 38.

A first branch pipe 191 and a second branch pipe 192 branched from the connection pipe 19 may be located on the fixing plate 36. A first valve 41 and a first pump 43 may be installed when connected to the first branch pipe 191, and a second valve 41' may be installed when connected to the second branch pipe 192. and a second pump 43' can be installed. The first valve 41 and the first pump 43, the second valve 41' and the second pump 43' may be seated on the fixing plate 36.

A first supply pipe 45 is connected to the first pump 43 and installed. A first cap connection pipe 48, which will be described below, may be connected to the first supply pipe 45. A second supply pipe 45' may be connected to the second pump 43'. A second cap connection pipe 48', which will be described below, may be connected to the second supply pipe 45'.

Here, the first valve 41 can control the flow of water from the first branch pipe 191 to the first supply pipe 45. The second valve 41' connected to the second branch pipe 32 can control the flow of water from the second branch pipe 192 to the second supply pipe 45'. The first pump 43 and the second pump 43' can provide a driving force for water flow to the first supply pipe 45 and the second supply pipe 45'.

Here, in order to supply water through both the first supply pipe 45 and the second supply pipe 45', the first pump 43 is driven, the first valve 41 is opened, and the second pump ( 43') is also driven and the second valve (41') is also opened. If water is to be supplied only through the first supply pipe 45, the first pump 43 is driven, the first valve 41 is opened, the second pump 43' is not driven, and the second pump 43' is not driven. The valve 41' is closed.

A plurality of light sources 47 may be installed surrounding the edge of the fixing plate 36. The light source 47 can express the beverage extraction process with light. For example, the light source 47 may emit light during the process of extracting a beverage from the capsule 1. The light source 47 may be an LED.

Meanwhile, a first cap connector 48 and a second cap connector 48' extend downward from the fixing plate 36. There may be a connection passage 49 inside the first cap connection pipe 48 and the second cap connection pipe 48'. Water delivered through the supply pipes 45 and 45' can be supplied through the connection passage 49.

There may be caps 50 at the ends of the first cap connector 48 and the second cap connector 48', respectively. The cap 50 may be made separately from the first cap connection pipe 48 or the second cap connection pipe 48' and may be combined with the first cap connection pipe 48. The cap 50 presses and secures the capsule 1. The shape of the cap 50 may vary depending on the type of capsule 1.

The cap 50 may have a perforation hole 52. The drill hole 52 may be installed connected to the connection passage 49. As can be seen in FIG. 20, the drill hole 52 may be installed at the outlet of the connection passage 49.

The structure of the drill hole 52 is well shown in FIG. 21. The perforation hole 52 forms a hole through which water can be injected into the capsule 1. The perforation hole 52 may be made of a material that can penetrate the corresponding part of the capsule 1. For example, the drill hole 52 may be made of a metal material.

The drill hole 52 has a body plate 520. The body plate 520 is shaped like a ring-shaped plate. A flow pipe 522 protrudes from the body plate 520. Water supplied through the supply pipes 45 and 45' may flow through the flow pipe 522. An injection passage 523 may be formed inside the flow pipe 522. A perforation blade 524 may be formed at the end of the flow pipe 522. The perforation blade 524 may have an overall oval shape. This is because the end of the flow pipe 522 is inclined to form the perforation blade 524. Accordingly, the length of the flow pipe 522 starts from the body plate 520 and gradually becomes longer as it goes from one side to the other side, and then gradually becomes shorter as it goes from the other side to one side.

The body plate 520 may have a plurality of fixing pieces 526. The fixing pieces 526 may be located at predetermined angular intervals at the edge of the body plate 520. The fixing piece 528 is used to fix the capsule 1 when the capsule 1 is mounted in the capsule seating space 540 and the cap 50 presses the capsule 1. It can be inserted by pressing or digging into the corresponding part. The tip of the fixing piece 528 may be formed to be inclined. One side of the fixing piece 528 may be sharp. The fixing piece 528 may serve to fix the capsule 1.

Figure 22 shows the capsule sheet 54. The capsule sheet 54 may be installed on the frame 31. A plurality of capsule seating spaces 540 may be formed in the capsule sheet 54. In the illustrated embodiment, two capsule seating spaces 540 are formed. A plurality of protrusions 542 are arranged in a row at the bottom of the capsule seating space 540. Adjacent to the protrusion 542, a discharge hole 543 through which the extracted beverage passes is formed. A plurality of the discharge holes 543 may also be formed in a row.

The capsule detection unit 59 can detect that the capsule 1 is seated in the capsule seating space 540. The capsule detection unit 59 may be installed on the fixed guide 58. The capsule detection unit 59 may be composed of, for example, an ultrasonic sensor, a laser sensor, a camera, etc., and any module or device capable of detecting the capsule 1 may be applied. In order not to interfere with the sensing operation of the capsule detection unit 59, the guide plate 546, which will be described below, may be made of a transparent material.

An installation slot 545 may be formed surrounding one side of the capsule seating space 540. The installation slot 545 may be formed to penetrate the capsule seat 54 through the bottom of the capsule seating space 540. The installation slot 545 may have a predetermined radius of curvature. A guide plate 546 (see FIG. 15) may be installed in the installation slot 545. The guide plate 546 can guide the capsule 1 to the capsule seating space 540. A guard 547 may be installed on the opposite side of the guide plate 546. The guard 547 surrounds the front portion of the capsule seating spaces 540. The guard 547 divides the area where the capsule 1 is installed from other areas and can prevent external forces from arbitrarily acting on the capsule 1. However, the guard 547 is not necessarily necessary.

As can be seen in FIG. 17, a hopper 56 may be installed below the capsule sheet 54. The hopper 56 collects the beverage that has passed through the discharge hole 543. The hopper 56 may be located at each location corresponding to each capsule seating space 540. The hopper 56 has discharge pipes 57 and 57'. The first discharge pipe 57 is where the beverage extracted by the water supplied through the first supply pipe 45 flows, and the second discharge pipe 57' is where the beverage supplied through the second supply pipe 45' flows. This is where the beverage extracted by water flows. The beverage that has passed through the first discharge pipe 57 and the second discharge pipe 57' can be delivered to a cup.

There may be a shielding plate 570 at the ends of the first discharge pipe 57 and the second discharge pipe 57'. The first discharge pipe 57 and the second discharge pipe 57' pass through the shield plate 570. The shielding plate 570 is a part that shields the opening formed in the lower part of the housing 32. For reference, the first discharge pipe 57 and the second discharge pipe 57' may directly penetrate the housing 32 without the shielding plate 570. In this case, there is no penetration part in the housing 32 that must be shielded by the shielding plate 570.

The first discharge pipe 57 and the second discharge pipe 57' penetrate the shielding plate 570 so that their outlets are exposed to the outside, or the first discharge pipe 57 and the second discharge pipe 57' These outlets are not exposed to the outside without penetrating the shielding plate 570, and a plurality of holes are formed in the shielding plate 570 to allow the extracted beverage to be discharged to the outside.

Meanwhile, as can be seen in FIG. 17, a distance sensor 572 may be installed at the edge of the shielding plate 570 or at the edge of the opening of the housing 32 where the shielding plate 570 is installed. The distance sensor 572 can measure the distance to the cup located below the extractor 30.

The first discharge pipe 57 and the second discharge pipe 57' may extend through the lower part of the housing 32 toward the cup. The outlets of the first discharge pipe 57 and the second discharge pipe 57' may be spaced apart from each other by a predetermined distance. The distance between the outlets of the first discharge pipe 57 and the second discharge pipe 57' can be an interval that allows beverages to be delivered to one cup at the same time. That is, the gap between the outlets of the first discharge pipe 57 and the second discharge pipe 57' can be set to be smaller than the inlet diameter of a typical cup. This is to allow one cup to receive the beverage coming out of the first discharge pipe 57 and the second discharge pipe 57' at the same time.

Additionally, the gap between the outlets of the first discharge pipe 57 and the second discharge pipe 57' must be greater than twice the thickness of the cup wall. According to this structure, beverages coming out of the first discharge pipe 57 and the second discharge pipe 57' can be received in separate cups.

As shown in Figure 22, a fixing guide 58 protrudes from the capsule sheet 54. The fixing guide 58 may be formed to stand upright on the surface of the capsule sheet 54. A predetermined space is formed inside the fixed guide 58 by passing up and down, and the movable guide 38 can be movably positioned in the space inside the fixed guide 58.

A moving guide 60 may be installed within the frame 31 or the fixing guide 58 of the capsule sheet 54. The movement guide 60 may serve to guide the movement of the movement tool 70, which will be described below. The configuration of the moving guide 60 is clearly shown in FIG. 23. The moving guide 60 is installed on the frame 31 and may extend long in one direction within the fixed guide 58.

A rack gear 62 may be formed along one side of the moving guide 60. The rack gear 62 may be formed in a plurality of rows long in the height direction of the moving guide 60. In this embodiment, the rack gear 62 is formed in two rows side by side along the moving guide 60.

A fixing piece 64 may be provided at the lower part of the moving guide 60. The fixing piece 64 is a part coupled to the frame 31. A coupling hole 64' may be formed in the fixing piece 64. A fastener for fastening to the frame 21 may pass through the coupling hole 64'.

A pipe interference avoidance portion 66 may be formed through the upper part of the moving guide 60 to avoid interference with the connection pipe 19 or the power line 18. By providing the pipe interference avoidance portion 66, it is possible to prevent flow in the width direction of the branch pipes 191 and 192 and the connection pipe 19.

As shown in FIG. 23, there may be a moving tool 70 that moves along the moving guide 60. The moving tool 70 is coupled to the cover 34, so that the cover 34 and its internal parts can be moved by the movement of the moving tool 70. The moving tool 70 may move in a direction toward or away from the frame 31 along the moving guide 60. In this embodiment, the moving tool 70 can be lifted and lowered relative to the frame 31 along the moving guide 60.

The moving tool body 72 may form the skeleton of the moving tool 70. A penetrating portion 74 is formed through the moving tool body 72 in the vertical direction. The moving guide 60 may penetrate the penetrating portion 74. The moving tool body 72 may be fastened to one side of the moving guide 38 of the fixing plate 36. The moving tool body 72 may have a fastening hole 76 for fastening to the moving guide 38 side. The fastening of the moving tool body 72 with the moving guide 38 does not necessarily require the use of a fastening hole 76, but rather the part where the moving tool body 72 and the moving guide 38 come into contact. It can be concluded at any time.

A drive source seating portion 77 may be formed on the moving tool body 72. A second driving source 78 that provides driving force for movement of the moving tool 70 may be installed on the driving source seating portion 77. A geared motor may be used as the second driving source 78. Drive gears 79 rotated by the driving force of the second drive source 78 may be located on both sides of the moving tool body 72. The driving gear 79 is rotatably coupled to the second driving source 78 and interlocked with the rack gear 62. Since the moving guide 60 on which the rack gear 62 is formed is fixed to the frame 31, the drive gear 79, which rotates in engagement with the rack gear 62, follows the rack gear 62. Can be elevated. The cover 34 may be moved as the drive gear 79 is moved up and down along the rack gear 62.

Next, with reference to FIGS. 26 to 32, the configuration within the base 10 will be described. There may be a control unit 80 within the base 10. The control unit 80 can control the operation of the beverage device and control the display 16 on the base 10. The control unit 80 may be a printed circuit board on which various elements are mounted and a circuit is configured.

A water supply unit 82 may be installed within the base 10. The water supply unit 82 supplies water used when extracting a beverage from the capsule 1. The water supply unit 82 may include a water tank 84. The water tank 84 stores water needed for beverage extraction. The water tank 84 can be separated from the base 10 and filled with water. However, when the beverage device of the present invention is fixed, an external water supply source can be connected to the water tank 84. Alternatively, water can be supplied directly from an external water supply source without the water tank 84.

The water tank 84 may be located in a separate location from the control unit 80. A partition wall 120 is formed within the base body 12, so that the area where the water tank 84 is installed can be separated from the surrounding area by the partition wall 120. There may be a water tank inlet and outlet 126 on one side of the base 10. The water tank 84 can be moved in and out of the base 10 in a drawer manner through the water tank inlet and outlet 126.

A water container body 840 may form the skeleton of the water container 84. The water bottle body 840 may be roughly a flat hexahedron. Inside the water tank body 840, there is a storage space 840' where water is stored. A cover plate 841 may form the upper surface of the water bottle body 840. Here, the upper surface formed by the cover plate 841 is an outer surface with a relatively large area in the shape of a flat hexahedron. The cover plate 841 shields the open inlet of the water bottle body 840, allowing the storage space 840' to be easily opened and closed. Of course, the storage space 840' inside the water bottle body 840 may be shielded from the outside without the cover plate 841. However, by providing the cover plate 841, cleaning of the storage space 840' can be performed more easily. A seal (not shown) is located at the edge of the cover plate 841 or at a corresponding position of the bucket body 840, so that the edge of the cover plate 841 and the corresponding position of the bucket body 840 are positioned. Water leakage can be blocked.

There is a water container door 842 on one outer surface of the water container body 840. The water tank door 842 can open and close the water tank inlet and outlet 126. The bucket door 842 is made larger in area and size than one outer surface of the bucket body 840, so as to shield the bucket inlet and outlet 126.

The water tank body 840 may have a water tank inlet 844. The water tank inlet 844 may be located in the cover plate 841. By opening the water tank inlet 844, water can be injected into the storage space 840'. Therefore, as shown in FIG. 28, water can be injected into the storage space 840' through the water tank inlet 844 with the water tank 84 partially protruding outside of the base 10.

There may be a discharge connector 846 on one side of the water tank body 840. The discharge connector 846 may be located on an outer surface opposite to the water tank door 842. The internal pipe 86, which will be described below, may be coupled to the discharge connection port 846.

Meanwhile, the bottom of the storage space 840' of the water tank 84 may be formed to slope downward from one side to the other side. Here, it may be formed to be inclined downward toward the discharge connector 846. In this way, if the bottom of the storage space (840') slopes downward toward the discharge connection port (846), the stored water can easily flow toward the discharge connection port (846), and the water remaining at the bottom of the storage space (840') You can do without this.

There may be a coupling bar 848 at the rear of the water bottle body 840. There may be a coupling ball 849 at the free end of the coupling bar 848. The coupling ball 849 has a ball shape with a diameter larger than the diameter of the coupling bar 848. The coupling ball 849 is linked with a push-push type locking/ejection mechanism 85. When the coupling ball 849 is inserted into the locking/discharging mechanism 85 and pushes the internal structure, the coupling ball 849 is coupled to the locking/discharging mechanism 85, and in this state, the coupling ball 849 is again connected to the locking/discharging mechanism 85. When the water container 84 is pushed in the direction in which the coupling ball 849 moves forward, the push-push type locking/ejection mechanism 85 releases the coupling state of the coupling ball 849 and moves the coupling ball 849 in the opposite direction. It is pushed to . Through this operation, the water container 84 can be easily attached and detached from the inside of the base 10. The specific structure of the push-push type locking/ejection mechanism 65 is omitted for convenience.

An internal pipe 86 is coupled to the discharge connection port 846 of the water tank 84. Water in the water tank 84 may flow within the base 10 through the internal pipe 86. As shown in FIG. 32, the internal pipe 86 has a flow path 861 through which water flows inside the inner pipe body 860, and an insulating layer 862 surrounding the outer surface of the inner pipe body 860. This is formed. Heat transfer to the outside of water flowing through the flow path 861 may be blocked by the heat insulating layer 862. There is an external pipe body 864 surrounding the heat insulating layer 862.

In other words, the inner pipe 86 is a double pipe made of an inner pipe body 860 and an outer pipe body 864, and there is an insulating layer 862 between the inner pipe body 860 and the outer pipe body 864, so that the heat of water You can prevent it from being stolen from the outside. In addition, even if the user touches the internal pipe 86, he or she will not be at risk from heat. For reference, the connection pipe 19 may also have the same structure as the internal pipe 86.

There may be a sensor 88 in the internal pipe 86 corresponding to the outlet of the water tank 84. The sensor 88 can measure the amount of water taken out of the water tank 84. A main pump 90 may be installed in the internal pipe 86 through which water flows through the sensor 88. The main pump 90 may provide a driving force for flowing water in the water tank 84. The main pump 90 may use a small centrifugal pump.

The water supply unit 82 has a boiler 92. The boiler 92 supplies heat to water passing through the main pump 90. The boiler 92 has a heater such as a sheath heater or a cartridge heater inside, so it can heat the delivered water to a desired value. There may be various methods of heating water in the boiler 92 other than heaters. For example, water can be heated by placing a heating means in a pipe installed inside the boiler through which water passes. The temperature of the water leaving the boiler 92 can be set to a value desired by the user. For this purpose, the boiler 92 has a temperature sensor (not shown) to control the temperature of water heated in the boiler 92. Water discharged from the boiler 92 may be delivered to the connection pipe 19.

On one side of the base 10, there may be a power port 94 for connecting an external power source and a power switch 96 for using the power supplied to the power port 94. The power port 94 and power switch 96 may be placed on one side of the rear portion of the base 10.

There is a pipe connector 124 in the base 10 to connect the connector 19. The connection pipe 19 is connected to the pipe connector 124 so that water delivered from the water supply unit 82 can be delivered to the extraction unit 30. There is a power line connector 122 adjacent to the pipe connector 124. The power line 18 may be connected to the power line connector 122.

Hereinafter, the operation of an embodiment of the present invention having the above-described configuration will be described in detail.

In the present invention, the extraction unit 30 can be moved by the support leg 20 installed on the base 10. As shown in FIG. 3, the extractor 30 can be lifted up and down with respect to the base 10. In Figure 3 (a), the extraction unit 30 is shown relatively close to the base 10, and in Figure 3 (b), the extraction unit 30 is shown in a state relatively close to the base 10. A state that is relatively far away is shown.

The position of the extraction unit 30 can be adjusted basically by changing the length of the leg driving unit 28. In the illustrated embodiment, the connection angle between the support leg 22 and the connection leg 24 varies depending on the length of the leg driving unit 28, thereby adjusting the position of the extractor 30.

When the length of the leg driving unit 28 is increased as shown in FIG. 7, the support link 22 and the connection link 24 form almost a right angle, and the connection frame 26 connected to the connection link 24 )'s position increases.

Conversely, when the length of the leg driving unit 28 is relatively short as shown in FIG. 6 compared to FIG. 7, the support link 22 and the connection link 24 form an acute angle, and the connection link 24 ) The position of the connection frame 26 connected to ) is lowered.

Increasing and lowering the overall height of the extraction unit 30 can be achieved by adjusting the length of the leg driving units 28 to be the same. However, when the lengths of the leg driving units 28 are adjusted differently, the angle of the connecting frame 26 with respect to the base 10 changes, and the extractor 30 may be tilted in various directions.

For reference, in the device of the present invention, the leg drive unit 28 can be configured to connect the joint 26 and the connection frame 26 without the support link 22 and the connection link 24. There is also. In this state, if the length of the leg driving unit 28 is varied, the position of the connection frame 26, that is, the height of the extraction unit 30, can be adjusted. At this time, the joint 26 may be rotated by a predetermined angle with respect to the base 10.

Meanwhile, it will be explained that the beverage in the capsule 1 is extracted in the device of the present invention. In order to mount the capsule 1 for beverage extraction into the capsule seating space 540, the capsule seating space 540 of the capsule seat 54 must be exposed to the outside. For this, the cover 34 must be installed in the capsule seating space 540. All you need to do is rise relative to the frame (31).

In order for the cover 34 to rise, the second drive source 78 must be driven. The driving gear 79 rotates by driving the second driving source 78, and the driving gear 79 is interlocked with the rack gear 62. The driving gear 79 moves to the upper part of the moving guide 60 along the rack gear 62, and the moving tool 70 moves the moving guide 60 together by the driving gear 79. moves along. The moving tool 70 is coupled to the moving guide 38 of the fixing plate 36 fixed to the cover 34, and as a result, the cover 34 rises. The state in which the cover 34 is raised in this way is shown in (a) of FIG. 24.

The cover 34 rises with respect to the frame 31 to expose the capsule seating space 540 of the capsule sheet 54. Figure 25(a) shows the capsule seating space 540 in an exposed state.

The state in which the user places the capsule 1 in the capsule seating space 540 is shown in FIGS. 24(b) and 25(b). The capsule 1 does not have to be seated in all of the capsule seating spaces 540. However, when extracting a beverage from two capsules (1), the capsules (1) are seated in all of the capsule seating spaces (540).

Next, the cover 34 is moved in the opposite direction from above. When the second drive source 78 is driven in the opposite direction, the moving tool 70 moves downward along the moving guide 60 by interlocking the driving gear 79 and the rack gear 62 and moves the cover 34. ) also moves toward the frame 31.

As the cover 34 moves, the fixing plate 36 also moves, and the cap 50 provided on the fixing plate 36 also descends. Figure 24(c) shows the cover 34 seated on the frame 31. In this process, the cap 50 also descends and presses the capsule 1, and in this process, a hole is formed in the capsule 50 by the perforation hole 52. The state in (c) of Figure 24 is a state in which beverage can be extracted from the capsule 1.

In this state, the aluminum cap of the capsule 1 is in close contact with the protrusion 542 at the bottom of the capsule seating space 540, and when strong pressure is applied by injection of water, the aluminum cap is torn and the beverage is ejected. You can.

Next, water is supplied from the water supply unit 82 through the connection pipe 19. The supply of water to the capsule 1 can be controlled by the control unit 80. For water supply, the main pump 90 is operated to supply water from the water tank 84 to the boiler 92. In the boiler 92, the water temperature is controlled to a predetermined value by the control unit 80. For example, in the case of a capsule 1 containing coffee, the temperature within the capsule 1 is generally between 80 and 90 degrees Celsius. The boiler 92 heats water accordingly.

In this way, water at a predetermined temperature in the boiler 92 can flow through the first branch pipe 191 and the second branch pipe 192 of the connection pipe 19. Water is supplied through the first branch pipe 191 and the second branch pipe 192 through the first valve 41, the first pump 43, and the second valve 41' and the second pump 43'. ) is used.

If water is supplied through both the first supply pipe 45 and the second supply pipe 45' to extract beverages from the two capsules 1 simultaneously, the first pump 43 must be driven. The first valve 41 is opened, the second pump 43' is also driven, and the second valve 41' is also opened.

In order to ensure that the beverage is extracted only from one side of the capsule 1, for example, water may be supplied only through the first supply pipe 45. In this case, the first pump 43 is driven and the first valve 41 is opened, and the second pump 43' is not driven and the second valve 41' is closed.

Conversely, in order to ensure that the beverage is extracted only from the other capsule 1, water needs to be supplied only through the second supply pipe 45'. To this end, the second pump 43' is driven and the second valve 41' is opened, and the first pump 43 is not driven and the first valve 41 is closed. In this way, various methods of extracting beverages from the capsules 1 are performed through control of the control unit 80 according to the user's selection.

Meanwhile, the beverage extracted from the capsule 1 may pass through the hopper 56 and be discharged into a cup through the discharge pipes 57 and 57'. For this purpose, the cup is placed on the base 10 in advance before the start of beverage extraction. When extracting a beverage from two capsules (1), two cups can be positioned. This is a case where the beverage extracted from two capsules (1) is received separately in each cup.

If you want to mix the drinks extracted from two capsules 1, place the cup in a position to receive the drinks coming out of the discharge pipes 57 and 57' at the same time. In this case, the inlet diameter of the cup must be larger than the distance between the outlets of the first discharge pipe 57 and the second discharge pipe 57'. Of course, it does not matter if the drinks coming out of the first discharge pipe 57 and the second discharge pipe 57' are mixed in separate cups.

After extraction of the beverage is completed, the cover 34 is opened. That is, in the reverse order to that shown in FIG. 24, the cover 34 is opened and the capsule 1 is removed from the capsule sheet 54.

Hereinafter, the operation of the beverage device according to an embodiment of the present invention having the above structure will be described in more detail with reference to the drawings.

Figure 33 is a block diagram schematically showing the connection of the control unit and the components connected to the control unit constituting the beverage device of the embodiment of the present invention, Figure 34 is a flow chart showing the operation of the beverage device of the embodiment of the present invention, and Figure 35 is the present invention. It is a flow chart showing the process of adjusting the height of the extraction unit in the beverage device of an embodiment of the invention, and Figure 36 is a flow chart showing the process of leveling the extraction section in the beverage device of an embodiment of the present invention.

The beverage device may be installed on the base top plate 14 forming the upper surface of the base 10. The base top plate 14 may be provided with a display 16. The display 16 can input settings and commands for the operation of the beverage device through a user's touch operation. Additionally, the display 16 can display screens about operation steps of the beverage device.

The beverage device includes an extraction unit 30 that extracts a beverage by injecting water into the capsule 1 and a plurality of support legs 20 that support the extraction unit 30 and elevate the extraction unit 30. can do.

The extraction unit 30 may have a housing 32 positioned at the lower part and a cover 34 positioned at the upper part based on the frame 31. The capsule 1 may be seated on the upper surface of the housing 32. The cover 34 can open and close the upper surface of the housing 332 by moving up and down. A capsule seating space 540 is formed on the upper surface of the housing 32, so that the capsule 1 can be seated in the capsule seating space 540.

The capsule detection unit 59 can detect that the capsule 1 is seated in the capsule seating space 540. The capsule detection unit 59 may be, for example, an ultrasonic sensor, a laser sensor, a camera, a scanner, etc. In this embodiment, when using a camera, the image described in the capsule 1 can be captured and information related to the capsule can be obtained through image analysis. For example, information such as the brand of the capsule, the type of capsule (tea, coffee, etc.), and the taste of the capsule can be confirmed in advance. Additionally, capsule-related information may be displayed on the display 16. For example, animations of different colors may be displayed on the display 16 depending on the type or taste of the capsule. Additionally, when a plurality of capsules are seated, a different color may be displayed for each capsule on the display 16.

The support leg 20 supports the housing 32 and can lift the housing 32 up and down. The first driving source 280 can drive the support leg 20 to elevate the housing 32. And, the moving tool 70 can lift and lower the cover 34. The second driving source 78 can drive the moving tool 70 to raise and lower the cover 34.

The beverage device may include a control unit 80. The control unit 80 can control the first driving source 280 and the second driving source 78, respectively, to drive the support leg 20 and the moving tool 70.

The touch sensor 348 installed on one side of the cover 34 can detect the user's touch operation. The touch sensor 348 may be installed on the upper surface of the cover 34, that is, the cover top plate 342. Of course, the touch sensor 348 may be installed on the front or side of the cover 34. When the user's touch is detected by the touch sensor 348, the control unit 80 can recognize it as an operation command for the beverage device and start an operation for extracting a beverage.

A voice recognition unit 350 that recognizes the user's voice may be provided inside the extraction unit 30. The control unit 80 may start an operation for extracting a beverage from the beverage device when the voice recognition unit 350 recognizes a voice corresponding to an operation command from the user.

The tilt sensor 269 installed inside the extraction unit 30 can measure the tilt of the extraction unit 30. Preferably, the tilt sensor 269 is installed inside the housing 32 to measure the tilt of the housing 32.

The control unit 80 determines whether the extractor 30 is horizontal based on the inclination measured by the tilt sensor 269, and if it is not horizontal, controls the first drive source 280 to control the support leg ( 20) can be driven so that the extraction unit 30 is horizontal.

The distance sensor 572 installed on the lower surface of the extraction unit 30 can measure the distance to a container, such as a cup, located below the extraction unit 30. Preferably, the distance sensor 572 may be installed on the lower surface of the housing 32.

The control unit 80 controls the second driving source 78 to drive the moving tool 70 based on the measured distance from the distance sensor 572 to the cup, thereby driving the extraction unit 30. Height can be adjusted. At this time, the height of the extraction unit 30 may be adjusted so that the distance from the extraction unit 30 to the cup is a set distance.

For example, if the measured distance from the extractor 30 to the cup is greater than the set distance, the extractor 30 is lowered until it reaches the set distance, and conversely, if it is smaller than the set distance, the set distance is lowered. The extraction unit 30 may be allowed to rise until the extraction unit 30 rises. The extraction unit 30 stops lifting when it reaches the set distance.

Referring to Figure 34, when power is applied to the beverage device (S101), a preheating operation may be performed (S102). While the preheating operation is in progress, a screen notifying that preheating is in progress may be displayed on the display 16. Additionally, when the preheating operation is completed (S103), a screen notifying that preheating is complete may be displayed on the display 16.

When the preheating operation is completed and the touch sensor 348 is touched or an operation command for the beverage device is input through voice recognition in the voice recognition unit 350, the extraction process of the beverage from the beverage device can begin. .

When the operation command is input (S104), the support leg 20 and the moving tool 70 are driven to raise the housing 32 and the cover 34 (S105). At this time, preferably, the housing 32 can be raised to a set maximum height.

When the capsule 1 is seated on the upper surface of the housing 32 with the cover 34 raised, the capsule detection unit 59 can detect the seating of the capsule 1. When the capsule detection unit 59 detects the seating of the capsule 1 (S106), the cover 34 may be lowered (S107).

At this time, when the capsule 1 is detected by the capsule detection unit 59, the cover 34 may be lowered immediately, but preferably, the cover 34 may be lowered after a set time has elapsed. The set time can be counted by a timer 98. In this embodiment, 1 to 3 seconds is preferable. This can prevent the cover 34 from immediately descending and colliding with the user's hand after the user places the capsule 1. If a certain amount of resistance or more occurs while the cover 34 is lowering, the lowering of the cover 34 may be stopped.

When a cup is placed below the extractor 30 with the cover 34 lowered, the distance sensor 572 installed at the bottom of the extractor 30 can detect the cup placed below. When the cup is detected by the distance sensor 572 (S108), the distance to the cup is measured (S109). Then, the housing 32 can be raised and lowered until the measured distance to the cup becomes the set distance (S110). In this embodiment, the set distance may be 1 to 3 cm. By bringing the extraction unit 30 close to the cup and then extracting the beverage, it is possible to prevent the beverage from splashing out of the cup during the beverage extraction process.

When the housing 32 reaches the set distance, water can be supplied to the capsule 1 and the beverage can be extracted into the cup (S111). When extraction of the beverage is completed, the housing 32 can rise (S112). This allows the user to avoid collision with the housing 32 when removing the cup.

In step S111, in another embodiment, a capsule 1 from which to extract a beverage may be selected by the user through the display 16, and water may be supplied to the selected capsule 1 to extract the corresponding beverage. . A plurality of capsule seating spaces 540 may be installed on the upper surface of the housing 32, and a user may seat one or more capsules 1 therein. When the capsule 1 is seated, the user can extract the beverage by selecting the capsule 1 corresponding to the beverage to be extracted. Additionally, in another embodiment, when the capsule 1 from which to extract the beverage is selected, the beverage may be extracted according to the extraction recipe corresponding to the capsule 1.

Referring to FIG. 35, as described above, when the capsule is detected and the cover 34 is lowered and the distance sensor 572 detects the cup at the lower part of the housing 32 (S201), The distance from the distance sensor 572 to the cup is measured in real time (S202).

If the measured distance to the cup is the set distance (S203), the housing 32 is maintained at the current height (S204). However, if the measured distance is not the set distance, the housing 32 is raised and lowered until the measured distance becomes the set distance.

That is, if the measured distance is greater than the set distance (S205), the housing 32 is lowered until the measured distance becomes the set distance (S206). Conversely, if the measurement distance is smaller than the set distance (S207), the housing 32 is raised until the measurement distance becomes the set distance (S208).

If the measured distance becomes the set distance in steps S206 and S208, the process may proceed again to step S202 and the subsequent process may be repeated.

The extraction unit 30 of the beverage device may be operated to be horizontal.

Referring to FIG. 36, the tilt sensor 269 installed inside the extraction unit 30 measures the tilt of the extraction unit 30 (S301). The control unit 80 determines whether the extraction unit 30 is horizontal based on the measured inclination (S302). The tilt measured by the tilt sensor 269 includes the tilt direction and angle.

As a result of the determination, if the extraction unit 30 is horizontal, the extraction unit 30 is maintained in the current horizontal state (S303). If it is not horizontal, at least one of the plurality of support legs 20 is driven to operate the extraction unit 30. ) can be made to be horizontal. At this time, the support leg corresponding to the inclined direction among the plurality of support legs 20 can be driven to make the extractor 30 horizontal.

In this embodiment, the beverage device is described as having three support legs 30. The directions of the three support legs 20 at the central point of the three support legs 20 are referred to as Z1, Z2, and Z3, respectively.

If the extraction unit 30 is not horizontal, it is determined whether it is inclined in the Z1 direction, and if it is inclined in the Z1 direction (S304), the support leg in the Z1 direction among the three support legs 20 is driven to extract the extraction unit ( 30) is horizontal (S305). At this time, in another embodiment, among the three support legs 20, the support leg in the Z1 direction is driven at reduced speed, and the remaining support legs in the Z2 direction and Z3 direction are driven at acceleration so that the extractor 30 is horizontal. there is.

If it is not tilted in the Z1 direction, it is determined whether it is tilted in the Z2 direction. If it is tilted in the Z2 direction (S306), the support leg in the Z2 direction among the three support legs 20 is driven so that the extractor 30 is horizontal. Make sure this happens (S307). At this time, in another embodiment, among the three support legs 20, the support leg in the Z2 direction is driven at reduced speed, and the remaining support legs in the Z1 direction and Z3 direction are driven at acceleration so that the extractor 30 is horizontal. there is.

If it is not tilted in the Z2 direction, it is determined whether it is tilted in the Z3 direction. If it is tilted in the Z3 direction (S308), the support leg in the Z3 direction among the three support legs 20 is driven so that the extractor 30 Make sure it is horizontal (S309). At this time, in another embodiment, among the three support legs 20, the support leg in the Z3 direction is driven at reduced speed, and the remaining support legs in the Z1 direction and Z2 direction are driven at acceleration so that the extractor 30 is horizontal. there is.

Meanwhile, the beverage device can adjust the tilt of the extraction unit 30 in real time by independently driving the plurality of support legs 20. For example, the extraction unit 30 can be tilted at an arbitrary angle by driving each of the three support legs 30. Additionally, if the variable length of the leg driving unit 28 constituting the three support legs 30 is adjusted, the inclination angle of the extractor 30 can be adjusted. When the inclination of the extraction unit 30 is adjusted, the direction in which the lower surface of the extraction unit 30 faces is adjusted.

Figure 37 is a schematic diagram showing the discharge position of the beverage according to the inclination of the extraction unit in the beverage device according to the embodiment of the present invention. In (a) of FIG. 37, the extraction unit 30 is horizontal and the lower surface of the extraction unit 30 is shown directly downward. In (b) of FIG. 37, the extraction unit 30 is tilted to the left and the lower surface of the extraction unit 30 is shown toward the left. Figure 37 (c) shows a state in which the extraction unit 30 is tilted to the right and the lower surface of the extraction unit 30 is directed to the right.

FIG. 38 is a diagram illustrating, for example, the tilt direction of the extraction unit 30 according to the arrangement and driving of the three support legs 20, and FIG. 39 shows the extraction by driving the three support legs 20. This is a diagram showing step by step the direction in which the unit 30 is inclined, that is, the direction in which the lower surface of the extraction unit 30 faces.

Referring to FIG. 38, the three support legs 20 are driven by respective first driving sources 78, and the extraction unit 30 is driven in the Z1, Z2, and Z3 directions by driving each of the support legs 20. It can be tilted in a direction based on a combination of these. In the drawing, among the three support legs 20, the first support leg is called M1, the second support leg is called M2, and the third support leg is called M3, and the directions in which these three support legs are tilted by driving are Z1 and Z2. ,It is called Z3.

When the first support leg (M1) is driven while the extractor 30 is horizontal, the extractor 30 is tilted in the Z1 direction, and when the second support leg (M2) is driven, the extractor 30 ) is inclined in the Z2 direction. When the third support leg M3 is driven, the extractor 30 is tilted in the Z3 direction. In this way, the tilting direction of the extractor 30 may vary depending on which of the first, second, and third support legs is driven. Additionally, the tilt angle may vary depending on the length at which the first, second, and third support legs are driven.

Referring to Figure 39, for example, when the three support legs 20 are driven step by step from stage 1 to stage 10, the tilt direction and degree of tilt of the extraction unit 20 are shown.

In the first stage, the slopes in the Z1, Z2, and Z3 directions are all 0, and the extraction unit 30 is in a horizontal state. In this case, the direction D toward which the lower surface of the extraction unit 30 faces may be the center.

In stage 2, the Z3 direction maintains a slope of 0 and is not tilted, but the Z1 and Z2 directions are tilted by 1. Therefore, in step 2, D is tilted in the Z1 and Z2 directions simultaneously, so it appears to be tilted in the middle direction between the Z1 and Z2 directions.

In step 3, the slope in the Z1 direction becomes 2, making it tilt further in the Z1 direction. In this case, D may appear in the Z1 direction.

In this way, as the slope in the Z1, Z2, and Z3 directions changes at each stage from stage 4 to stage 10, the slope direction and degree of slope of the extraction unit 30 change.

The numbers representing the degree of slope are relative values and indicate the relative size of the slope.

The direction and degree of inclination from steps 1 to 10 shown in FIG. 39 can be expressed as shown in FIG. 40.

Figure 41 shows the trajectory of the direction in which the lower surface of the extraction unit 30 faces during steps 1 to 10. The trajectory can become a spiral by adjusting the direction and angle of tilt as each step progresses. Of course, the direction and angle of the slope can be adjusted differently to create a random trajectory, or a set pattern can be drawn.

Figure 42 shows an example in which the direction D facing the lower surface of the extraction unit 30 is spiral, as shown in Figure 41. The tilt sensor 269 measures the tilt of the extractor 30 (S401), and the control unit 80 determines whether the extractor 30 is horizontal based on the measured tilt (S402) . If the extraction unit 30 is not horizontal, the operation described in FIG. 36 is performed to make the extraction unit 30 horizontal (S403). When the extraction unit 30 is horizontal, the direction D in which the lower surface of the extraction unit 30 faces is directly downward.

With the extractor 30 in a horizontal state, the support legs 20 are sequentially driven at each stage to achieve the direction and angle of inclination at each stage shown in FIG. 41 (S404). When it runs to the final step (S405), it ends.
