Description

beverage device

[0001] The present invention relates to a beverage device for extracting a beverage contained in a capsule.

[0002] Capsules, which contain the ingredients for beverage production, are widely used. These capsules contain the beverage ingredients in a sealed container, and the user uses a mechanical device to pass water through the capsule to extract the beverage. Coffee machines are a representative example of beverage devices that utilize capsules. Recently, capsules are being used to make and consume not only coffee but also various other beverages and beverage ingredients.

[0003] One such device for extracting beverages using capsules is disclosed in Korean Patent Publication No. 10-2015-0017541, Prior Art 1. Prior Art 1 has the following problems: the entire device is integrated and all components are contained within a single housing, preventing the extraction unit from varying its operation; and the entire device always has a consistent shape, making it difficult to attract consumers' attention from a design perspective. Furthermore, the portion through which the extracted beverage is discharged is fixed, preventing the use of various types of cups.

[0004] In addition, prior art document 2, which is Korean registered patent No. 10-0924447, discloses an espresso coffee extraction device, but since the distance between the original liquid extraction port and the base is fixed, there is a problem in that cups higher than a certain height cannot be used, and since there is no change in appearance, it always has a consistent appearance, making it difficult to attract the attention of consumers in terms of design.

[0005] Prior art document 3, Korean Patent No. 10-0924447, discloses a coffee extraction device. This device focuses solely on the coffee extraction function, requiring the user to wait without any information until the coffee is dispensed after inserting the capsule. Furthermore, the device does not allow for adjustment of the distance between the cup and the outlet.

[0006] Next, a device for extracting a beverage using a capsule is disclosed in Korean Patent No. 10-1260504, a prior art document 4. However, this device is also focused only on the function of extracting a beverage, and there is a problem in that it does not provide distance control between the cup and the outlet or information provision to the user.

[0007]

[0008] The purpose of the present invention is to solve the conventional problems as described above, and to separate the extraction unit for extracting a beverage from other parts of the beverage device and to raise and lower it with a single driving source.

[0009] The purpose of the present invention is to enable the extraction unit to be elevated along a predetermined path when elevated relative to the base.

[0010] An object of the present invention is to provide a driving source that provides driving force for movement of an extraction unit and is installed in the extraction unit.

[0011] In the present invention, a lifting frame is raised and lowered by a single driving source relative to a fixed frame fixed by a support leg, thereby raising and lowering an extraction part.

[0012]

[0013] In order to achieve the above-described purpose, the beverage device according to the present invention has an extraction unit positioned spaced apart from each other on a base, which is elevated by the driving force of one driving source.

[0014] In the present invention, the driving source is installed in a lifting frame mounted on an extraction unit, and causes the lifting frame to be raised or lowered relative to a support leg fixed to a base.

[0015] The above support leg is connected to a fixed frame located within the above extraction section, and the lifting frame is raised and lowered relative to the fixed frame.

[0016] The above driving source is installed on the above lifting frame and is linked to a linkage nut installed on the above fixed frame to raise and lower the above lifting frame.

[0017] The beverage device of the present invention may include a base that is fixed to the floor, a support leg that is fixedly installed on the base, an extraction unit that is supported by the support leg and is elevated from the upper portion of the base and has a configuration for extracting a beverage inside, and a driving source that is installed on the extraction unit and provides a driving force to move the extraction unit with respect to the support leg.

[0018] The above support legs can be installed on the base in multiple numbers at regular intervals.

[0019] The above support leg may include a first support bar installed on the base and a second support bar connected to the first support bar and coupled to a fixed frame positioned within the extraction section.

[0020] The above support leg may further include a first moving bar having one side connected to the first support bar and the second support bar so as to be able to rotate relative to each other, and a second moving bar having the second moving bar connected to the extraction part and the first moving bar so as to be able to rotate relative to each other.

[0021] The first moving bar may be composed of a first moving bar body and a first moving bar cover coupled to the first moving bar body, and the first moving bar cover may be coupled to the first moving bar body while the first moving bar body is coupled to the first support bar and the second support bar and also coupled to the second moving bar.

[0022] The above support legs may be provided in multiple numbers, and the support legs are connected to each other by a fixed frame while being fixed to the base, and the lifting frame installed in the extraction section can be raised and lowered with respect to the fixed frame by the driving force of the driving source.

[0023] The driving source can be installed on the above-mentioned lifting frame, and the lifting frame can move with the driving force of the driving source with respect to the above-mentioned fixed frame.

[0024] The above driving source includes a driving motor and a lead screw rotated by the driving motor, and the lead screw can be linked with a linkage nut installed on the fixed frame.

[0025] The above driving motor can be mounted on a hopper installed on the above lifting frame, and the lead screw can be coupled by penetrating the hopper and penetrating a coupling nut on the above fixed frame.

[0026] The above fixed frame may be provided with a polygonal fixed frame body having a hole formed therein, a linkage body positioned in the hole and connected to the fixed frame body by a connecting bar, and a linkage nut provided on the linkage body and linked with the lead screw of the driving source.

[0027] The above-mentioned lifting frame may be provided with an lifting slot in which the connecting bar is guided and moved in the lifting frame body, and a plurality of hanging steps that are hung on the fixed frame may be formed at the upper end of the above-mentioned lifting frame body.

[0028] The first support bar and the second support bar constituting the above support leg are tubular in shape so that wires or hoses can pass through the inside.

[0029] The above first support bar can be connected to a joint installed on the base.

[0030] The second support bar may be extended obliquely from the first support bar and may be connected to a fixed frame positioned within the extraction section to guide the elevation of the extraction section.

[0031] The above support legs can be fixed to the base in multiple numbers at regular intervals, and can be fixed to the base at a location outside the area where the extraction part is located and the display installed on the base.

[0032]

[0033] The beverage device according to the present invention may have at least one of the following effects.

[0034] In the present invention, an extraction unit configured for extracting a beverage is separated from a base having a water supply unit, and the extraction unit is raised and lowered relative to the base while being supported by support legs. At this time, the extraction unit is raised and lowered using a single driving source. Since the extraction unit is raised and lowered using a single driving source, the control for the elevation of the extraction unit is facilitated.

[0035] In the present invention, the extraction unit is raised and lowered relative to the first and second support bars of the support legs fixedly installed on the base. In particular, the extraction unit is raised and lowered relative to a fixed frame that is coupled to the second support bar and fixed at a predetermined height on the base, so that the extraction unit can be raised and lowered along a predetermined path. Accordingly, the extraction unit mechanically moves along a predetermined path to accurately supply beverage to the cup, and there is an effect in that the extraction unit is stably supported by the support legs.

[0036] In the present invention, a driving source that provides power for the elevation of the extraction section is installed on a lifting frame fixed to the extraction section. Therefore, since the lifting frame is directly elevated by the driving force of the driving source, power transmission can be efficiently achieved, and since the elevation stroke of the extraction section can be relatively large, the overall height of the extraction section can be relatively reduced.

[0037] In addition, in the present invention, the lifting frame is raised and lowered by a single driving source with respect to a fixed frame fixed by a support leg, so that the extraction unit equipped with the lifting frame is raised and lowered. In this structure, the lifting frame can be guided and moved with respect to the fixed frame, so that the extraction unit is stably supported by the support leg, and the movement of the extraction unit is guided by the fixed frame, so that the extraction unit is raised and lowered along a predetermined path, thereby achieving the effect of stably performing the operation of the extraction unit.

[0038] In the present invention, in order to elevate an extraction unit supported by a plurality of support legs, the first and second support bars of the support legs are fixed to a base and the extraction unit is elevated using a single driving source. In this way, even when a plurality of support legs are used, the extraction unit can be elevated using a single driving source, thereby stably supporting the extraction unit while allowing more efficient control of the elevation of the extraction unit.

[0064] Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. When designating components in each drawing, it should be noted that, where possible, identical components will be given the same reference numerals, even if they appear in different drawings. Furthermore, when describing embodiments of the present invention, if a detailed description of a related known structure or function is deemed to hinder understanding of the embodiments of the present invention, such detailed description will be omitted.

[0065] As can be seen in FIGS. 1 and 2, the beverage device of the embodiment of the present invention has an extraction unit (30) installed spaced apart from the upper portion of a base (10) placed on the floor. A support leg (20) can be used to space the extraction unit (30) apart from the base (10). In the present invention, the extraction unit (30) can be moved closer to and further away from the base (10) while being supported by the support leg (20). This operation of the extraction unit (30) causes the extraction unit (30) to descend in the direction of gravity or rise in the direction opposite to gravity. In other words, the extraction unit (30) can be raised and lowered with respect to the base (10).

[0066] The above base (10) can be placed on the ground. The base (10) may have a plate shape with a predetermined thickness. The base (10) supports the entire beverage device and ensures that the center of gravity of the entire beverage device is on or adjacent to the base (10). In the illustrated embodiment, the base (10) has a flat hexahedral shape. However, the base (10) may have various plate shapes, such as a circular plate shape or a polygonal plate shape, as long as it is flat.

[0067] The appearance and skeleton of the above base (10) can be formed by a base body (12), a base cover (13), and a base top plate (14). The base body (12) has a side wall (121) that protrudes to a predetermined height around the edge of a bottom plate (120) forming the floor. A water tank inlet (121') is opened on one side of the side wall (121). The water tank inlet (121') can be formed on one side when the base (10) is viewed from the front.

[0068] A control unit partition wall (122) and a water tank partition wall (123) may be formed on the above-described floor plate (120). A control unit (80), which will be described below, may be installed in a space partitioned by the control unit partition wall (122), more precisely, a space partitioned by the control unit partition wall (122) and the side wall (121). The control unit partition wall (122) may be formed approximately parallel to a side wall (121) that forms the front of the base (10). The control unit partition wall (122) may serve to block moisture and heat inside the base (10) from being transmitted to the control unit (80).

[0069] There may be a leg support rib (122') connected to the control unit partition wall (122). The leg support rib (122') may be formed in an approximately semi-cylindrical shape. The leg support rib (122') serves to support the base cover (14) and the base top plate (16) at the location where the joint (228) constituting the support leg (20) is installed. A leg support rib (122") having the same function as the leg support rib (122') may be located at the middle portion of the rear edge of the base body (12). The leg support rib (122") may be located at a position corresponding to that of the support leg (20) located at the rear of the base (10), as can be seen in FIGS. 4 and 18.

[0070] The space where the water tank (84) to be described below is positioned can be partitioned from the surroundings by the water tank compartment wall (123). The water tank compartment wall (123) can be formed adjacent to the side wall (121) in which the water tank inlet / outlet (121') is formed. The water tank compartment wall (123) prevents moisture from the water tank (84) from being transferred to other parts inside the base (10).

[0071] A boiler mounting portion (124) is formed in the rear of the base (10) inside the base body (12) and in an area opposite to the area partitioned by the water tank partition wall (123), or in other words, at a position adjacent to one rear edge of the base body (12). A plurality of through holes (125) may be formed in the bottom plate (120) corresponding to the boiler mounting portion (124). In the present embodiment, a plurality of through holes (125) are formed in two rows. The rows of through holes (125) correspond to the edges on both sides of the boiler module (87). Heat from the boiler module (87) can be discharged to the outside through the through holes (125).

[0072] There is a base cover (13) to cover the upper part of the base body (12). The edge of the base cover (13) may be at a position corresponding to the side wall (121). Components installed in the base body (12) may be shielded by the base cover (13). A plurality of through holes (13-1, 13-2, 13-3) may be formed in the base cover (13). Wires, hoses, etc. may pass through the through holes (13-1, 13-2, 13-3). For example, wires may pass through the first through hole (13-1) and the second through hole (13-2), and hoses may pass through the third through hole (13-3). A pair of fastening holes (not given a drawing symbol) may be formed at positions adjacent to the through holes (13-1, 13-2, 13-3).

[0073] A display home (130) may be formed in the above base cover (13). The display home (130) may be rectangular. A display (16), which will be described below, is positioned in the display home (130). An operating unit hole (132) may be formed in the above base cover (13). An operating unit (18), which will be described below, may be exposed to the outside through the operating unit hole (132).

[0074] A base top plate (14) may be installed on the base cover (13). The base top plate (14) may be made of tempered glass. Accordingly, the content displayed on the display (16) installed in the display home (130) of the base cover (13) can be viewed from the outside through the base top plate (14). A plurality of through holes (14-1, 14-2, 14-3) may also be formed in the base top plate (14). The through holes (14-1, 14-2, 14-3) in the base top plate (14) are located at positions corresponding to the through holes (13-1, 13-2, 13-3) in the base cover (13). Among the through holes (14-1, 14-2, 14-3) in the above base plate (14), wires can pass through the first through hole (14-1) and the second through hole (14-2), and a hose can pass through the third through hole (14-3). A pair of fastening holes (not given a drawing symbol) can be formed at positions adjacent to the through holes (14-1, 14-2, 14-3).

[0075] A display (16) may be provided between the base plate (14) and the base cover (13). The display (16) may occupy most of the upper surface of the base (10). The display (16) may be configured by attaching a touch display module to the lower surface of the base plate (14), which is made of tempered glass, using an OCA film.

[0076] The operating unit (18) is positioned in the operating unit hole (132) and can be exposed to the upper surface of the base (10) through the base cover (13). The operating unit (18) can be actuated by a user's touch. That is, the operating unit (18) is exposed through the operating unit hole (132), but is shielded by the base top plate (14) made of tempered glass and can be viewed from the outside.

[0077] A support leg (20) may be installed on the base (10). The support leg (20) may support the extraction unit (30). The support leg (20) may support the extraction unit (30) so that it can be raised and lowered. A plurality of support legs (20) may be used. In the illustrated embodiment, three support legs (20) are used.

[0078] The above support legs (20) can be arranged at a predetermined interval based on the center of the extraction part (30). As can be seen in FIG. 3, three support legs (20) can be arranged at 120-degree intervals based on the center of the extraction part (30). The support legs (20) are arranged on the base (10) in an area outside the perimeter of the extraction part (30). The area where the support legs (20) are connected to the base (10) is outside the area where the extraction part (30) is located. This is well illustrated in FIG. 3. In this way, the extraction part (30) can be stably supported by the support legs (20) supporting the extraction part (30).

[0079] The above support leg (20) may have a first support bar (22) and a second support bar (23). The first support bar (22) and the second support bar (23) are separated in the illustrated embodiment. However, the first support bar (22) and the second support bar (23) may be formed as one piece.

[0080] The first support bar (22) may be installed upright on the base (10). The second support bar (23) may extend obliquely at a predetermined angle with respect to the first support bar (22). Each of the second support bars (23) extends obliquely toward the extraction section (30). Therefore, the imaginary extension lines of the second support bars (23) may meet at one point.

[0081] The above first support bar (22) and second support bar (23) both have a pipe structure. This is to allow wires and / or hoses (881, 882) to pass through the interior of the first support bar (22) and second support bar (23).

[0082] The configuration of the first support bar (22) and the second support bar (23) is described in detail with reference to FIG. 9. The first support bar (22) has a first support bar body (220) that forms the exterior and skeleton. The first support bar body (220) has a tubular shape. A first passage (221) passes through the first support bar body (220). Wires and / or hoses (881, 882) can pass through the first passage (221).

[0083] A hook (222) is formed at one end of the first support bar body (220). The hook (222) is for connection with a joint (228) to be described below. The hook (222) may be formed in multiple numbers at regular intervals. In the present embodiment, two hooks (222) are formed at regular intervals. When the hook (222) is connected to the joint (228), a cut portion (224) is formed at one end of the first support bar body (220) so that it can be elastically deformed. The cut portions (224) may also be formed in multiple numbers at regular intervals.

[0084] At the other end of the first support bar body (220), there is a pair of first connecting plates (226). The first connecting plates (226) are for rotatably connecting with the first moving bar (24) to be described below. Between the pair of first connecting plates (226), a pair of second connecting plates (236) of the second support bar (23) to be described below can be positioned. A hinge hole (227) is formed in each of the first connecting plates (226). The first hinge (242) of the first moving bar (24) to be described below is rotatably connected to the hinge hole (227).

[0085] A structure in which one side of the first support bar body (220) is fixed to the base (10) is described. FIG. 12 illustrates a configuration in which the first support bar (22) is fixed to the base (10). A joint (228) is installed at a position corresponding to the through-holes (14-1, 14-2, 14-3) in the base (10). The joint (228) can be coupled to the base (10) by fastening a screw that passes through a screw hole formed adjacent to the through-holes (14-1, 14-2, 14-3).

[0086] The skeleton of the above joint (228) is formed by a joint base (228'). A base protrusion (228") is formed protrudingly at the center of the joint base (228'). The base protrusion (228") may have a hemispherical shape. A joint hole (228e) is formed through the base protrusion (228") and the joint base (228'). The joint hole (228e) may be connected to the through holes (14-1, 14-2, 14-3). The hook jaw (222) of the first support bar (22) may be hooked onto a groove or protrusion formed on the inner surface of the joint hole (228e). A seal (229) is installed between the joint base (228') and the upper surface of the base (10) to perform a waterproofing function.

[0087] The second support bar (23) above has a second support bar body (230) that forms the exterior and skeleton. The second support bar body (230) has a tubular shape. A second passage (231) passes through the second support bar body (230). Wires and / or hoses (881, 882) can pass through the second passage (231).

[0088] A second fastening block (232) may be provided at one end of the second support bar body (230). The second fastening block (232) is for fastening to the fixed frame (26) to be described below. A second fastening hole (234) is formed in the second fastening block (232). A fastening screw is fastened to the fixed frame (26) by penetrating the second fastening hole (234).

[0089] At the other end of the second support bar body (230), there is a pair of second connecting plates (236). The second connecting plates (236) are for rotatably connecting with the first moving bar (24). Each of the second connecting plates (236) is formed with a hinge hole (237). A first hinge (242) of the first moving bar (24), which will be described below, is rotatably connected to the hinge hole (237). The hinge hole (237) of the second connecting plate (236) is concentric with the hinge hole (227) of the first connecting plate (226). The second connecting plate (236) may be positioned between the first connecting plates (226). Alternatively, the second connecting plates (236) and the first connecting plate (226) may be integrally connected to each other.

[0090] A first moving bar (24) is connected to the part where the first support bar (22) and the second support bar (23) are connected to each other so as to be rotatable at a predetermined angle. The first moving bar (24) is connected to the hinge hole (227) of the first support bar (22) and the hinge hole (237) of the second support bar (23). The other end of the first moving bar (24) is connected to the second moving bar (25) to be described below so as to be rotatable relative to each other.

[0091] The above first moving bar (24) may be composed of a first moving bar body (240) and a first moving bar cover (241). The first moving bar cover (241) may be press-fitted and joined to one side of the first moving bar body (240). In the illustrated embodiment, the first moving bar cover (241) is press-fitted and joined to the first moving bar body (240), but alternatively, it may be fastened using screws.

[0092] At one end of the first moving bar body (240), there is a first hinge (242). The first hinge (242) is rotatably installed in the hinge holes (227, 237) of the first support bar (22) and the second support bar (23). Corresponding to the first hinge (242), the first moving bar cover (241) also has a first hinge (242'). The first hinge (242') is also rotatably installed in the hinge holes (227, 237) of the first support bar (22) and the second support bar (23).

[0093] At the other end of the first moving bar body (240), there is a second hinge (243). A second hinge (243') may be located at a position of the first moving bar cover (241) corresponding to the second hinge (243). The second hinge (243') may be inserted into the interior of the second hinge (343).

[0094] There are coupling ribs (245, 245') at corresponding positions of the first moving bar body (240) and the first moving bar cover (241). These coupling ribs (245, 245') are ribs that can be press-fitted to each other. There may be coupling rods (247, 247') on the inside of the coupling ribs (245, 245'). The coupling rods (247, 257') can be fitted into each other and coupled.

[0095] The second moving bar (25) is connected to the first moving bar (24) so ​​as to be rotatable relative to the first moving bar (24). One end of the second moving bar (25) is connected to the first moving bar (24), and the other end is connected to an elevation frame (27) to be described below so as to be rotatable relative to the first moving bar (24) and the second moving bar (25) can rotate while changing the angle at which they are connected to each other. Accordingly, the first moving bar (24) and the second moving bar (25) rotate as if they are unfolded and folded, and the lifting and lowering of the fastening part (30) can give the feeling of a spaceship landing and taking off.

[0096] The second moving bar body (250) forms the exterior and frame of the second moving bar (25). The second moving bar body (250) may have a cross-section that is partially rectangular. A hinge hole (252) is formed at one end of the second moving bar body (250). The second hinge (243) of the first moving bar (24) is positioned in the hinge hole (252) and can be rotated relative to it.

[0097] On the other end of the second moving bar body (250), a pair of connecting pieces (253) are arranged side by side, and a hinge hole (254) is formed in each of the pair of connecting pieces (253). The hinge hole (254) is connected to the lifting frame (27) to be described below, so that the second moving bar (25) can rotate relative to the lifting frame (27).

[0098] The second moving bar body (250) may have an interference avoidance slot (256). The second support bar (23) may pass through the interference avoidance slot (256). The interference avoidance slot (256) is to avoid interference with the second support bar (23). The interference avoidance slot (256) extends a predetermined length in the longitudinal direction of the second moving bar body (250). The second support bar (23) passes through the interference avoidance slot (256). The second support bar (23) is fixed to the base (10) via the first support bar (22), so that when the second moving bar (25) operates, the interference avoidance slot (256) is required to have a length that does not interfere with the second support bar (23).

[0099] The second support bars (23) are connected to a fixed frame (26). The fixed frame (26) is well illustrated in FIG. 10. The fixed frame (26) is located at a position spaced apart from the base (10). The fixed frame (26) is connected to the second support bars (23) of the support legs (20) and is fixed. The fixed frame (26) can be connected to a plurality of the second support bars (23) and fixed at a predetermined height on the base (10). In this way, when the first support bars (22) and the second support bars (23) constituting the support legs (20) and the fixed frame (26) are fixed to the base (10), the extraction part (30) can be supported more stably and moved.

[0100] The skeleton of the above fixed frame (26) is formed by a fixed frame body (260). The above fixed frame body (260) is made in a polygonal shape. A through hole (260') is formed through the above fixed frame body (260). A part of the lifting frame (27) to be described below can be positioned to be raised and lowered in the through hole (260'). In the illustrated embodiment, the above fixed frame body (260) is hexagonal when viewed in plan view. However, the above fixed frame body (260) may be made in a polygonal shape.

[0101] The above-mentioned through-hole (260') has a linkage body (262). The linkage body (262) is located at the center of the through-hole (260') and is connected to the fixed frame body (260). A through-hole (263) may be formed through the linkage body (262). The through-hole (263) is a portion through which a discharge pipe (292) to be described below passes. The through-hole (263) may be located at the geometric center of the fixed frame (26). A linkage hole (264) may be formed through the linkage body (262). A linkage nut (265) may be located within the linkage hole (264). The linkage nut (265) is installed by inserting it into the communication hole (264). The linkage nut (265) is linked with a lead screw (282) of a driving source (28) to be described below. A female thread portion is formed on the inner surface of the above-mentioned linkage nut (265) so that it can be linked with the linkage screw portion (284) of the lead screw (282). Here, since the linkage nut (265) is fixed to the fixed frame (26), the lead screw (282) can be moved linearly with respect to the linkage nut (265), i.e., the fixed frame (26), by the rotation of the lead screw (282).

[0102] The above-mentioned linkage body (262) can be connected to the above-mentioned fixed frame body (260) by a connecting bar (266). In the illustrated embodiment, three connecting bars (266) are provided at regular intervals to connect the above-mentioned linkage body (262) and the fixed frame body (260).

[0103] The fixed frame body (260) may be provided with a leg connecting section (267). The second support bar (23) is connected to the leg connecting section (267). The second fastening block (232) of the second support bar (23) may be positioned and fastened to the leg connecting section (267). A fastening hole (268) may be formed in the leg connecting section (267). The leg connecting section (267) may be provided at a position corresponding to a position where the connecting bar (266) is connected to the fixed frame body (260). This is to increase the rigidity of the fixed frame body (260). The second fastening hole (234) of the second fastening block (232) and the fastening hole (268) of the leg connecting section (267) are located at positions corresponding to each other.

[0104] Next, the configuration of the lifting frame (27) will be described. The lifting frame (27) is raised and lowered relative to the support leg (20). As the lifting frame (27) is raised and lowered, the extraction unit (30) is raised and lowered. The lifting frame (27) is fixed to the housing (32) of the extraction unit (30) and can be raised and lowered together with the extraction unit (30).

[0105] The skeleton of the above-mentioned lifting frame (27) can be formed by an lifting frame body (270). The lifting frame body (270) can have a polygonal cylinder shape. In the illustrated embodiment, the lifting frame body (270) has a hexagonal cylinder shape. An internal space (270') can be formed inside the lifting frame body (270). The internal space (270') is formed by vertically penetrating the lifting frame body (270). The lifting frame body (270) makes the internal space (270') as wide as possible to avoid interference with surrounding components and reduce the load.

[0106] The above-mentioned lifting frame body (270) may have a plurality of lifting slots (271) formed in a vertical direction. The lifting slots (271) are to avoid interference with the connecting bar (266) of the fixed frame (26). The lifting slots (271) are provided so that the lifting frame (27) can be raised or lowered relative to the fixed frame (26) without interference with the connecting bar (266) when being raised or lowered. The number of the lifting slots (271) is three, corresponding to the number of the connecting bars (266).

[0107] On one side of the above-mentioned lifting frame body (270), there is a housing fastening part (272). The housing fastening part (272) may be formed to protrude in a centrifugal direction at the bottom of the above-mentioned lifting frame body (270). A fastening hole (272') may be formed in the above-mentioned housing fastening part (272). A screw is fastened to the housing (32) of the above-mentioned extraction part (30) by penetrating the above-mentioned fastening hole (272'). In this way, the above-mentioned lifting frame (27) can be coupled to the extraction part (30).

[0108] The above-described lifting frame body (270) may have a leg connecting portion (273). The leg connecting portion (273) may be formed to protrude in a centrifugal direction at the lower portion of the above-described lifting frame body (270). The leg connecting portion (273) may be located relatively higher than the housing fastening portion (272). The connecting piece (253) of the second moving bar (25) may be connected to the leg connecting portion (273). The leg connecting portion (273) and the connecting piece (253) of the second moving bar (25) may be connected to each other so as to be relatively rotatable by a hinge pin (254'). That is, the hinge pin (254') is used so that the second moving bar (25) can rotate in accordance with the elevation of the above-described lifting frame (27).

[0109] The lower portion of the above-described lifting frame body (270) may have a tray installation portion (274). A residual water tray assembly (not shown) may be installed in the tray installation portion (274). The tray installation portion (274) may be formed in an approximately ring shape. The upper portion of the above-described lifting frame body (270) may have a hook (275). When the above-described lifting frame (277) moves to the lowest position, the hook (275) may be hooked to the fixed frame (26) to prevent the above-described lifting frame (277) from lowering any further. The above-described hooks (275) are formed in pairs in an area where the above-described lifting slot (271) is not formed.

[0110] A fastening rod (276) may be formed on the inner surface of the above-described lifting frame body (270). A hopper (29), which will be described below, may be installed on the above-described fastening rod (276). The above-described fastening rods (276) are formed in pairs on the inner surfaces of the above-described lifting frame body (270) facing each other. The configuration of the above-described fastening rods (276) is well illustrated in Fig. 11.

[0111] A driving source (28) may be installed in the above-described lifting frame (27). The driving source (28) provides a driving force for the lifting frame (27) to be raised or lowered. The driving source (28) includes a driving motor (280) and a lead screw (282) that is rotated by the driving force of the driving motor (280). An interlocking screw portion (284) is formed surrounding the outer surface of the lead screw (282). The interlocking screw portion (284) is interlocked with the interlocking nut (265). The lead screw (282) is installed by penetrating the interlocking hole (264) in the above-described fixed frame (26), so that the interlocking screw portion (284) is interlocked with the interlocking nut (265). Since the fixed frame (26) having the above-described linkage nut (265) is fixed, the lead screw (282) can be moved relative to the fixed frame (26) by the rotation of the lead screw (282). Accordingly, the lead screw (282) and the driving motor (280) can be moved relative to the fixed frame (26), and when the driving source (28) is installed in the lifting frame (27), the lifting frame (27) can be moved relative to the fixed frame (26).

[0112] In the illustrated embodiment, a hopper (29) is installed on the lifting frame (27), and the driving source (28) is installed on the hopper (29). Therefore, in the illustrated embodiment, the hopper (29), the driving source (28), the lifting frame (27), and the housing (32) of the extraction unit (30) on which the lifting frame (27) is mounted can move together by the driving force of the driving source (28).

[0113] In the present invention, various components installed in the housing (32) of the extraction unit (30) can move relative to the support leg (20). More specifically, the extraction unit (30) can be elevated relative to the base (10) along the support leg (20) with respect to the first support bar (22) and the second support bar (23) of the support leg (20) fixedly installed on the base (10), and the fixed frame (26) fixed to the second support bar (23). At this time, the elevating frame (27), which is a component installed in the housing (32) of the extraction unit (30), the hopper (29) installed on the elevating frame (27), and the driving source (28) installed on the hopper (29) move relative to the support leg (20) and the fixed frame (26).

[0114] The above hopper (29) is a component that is substantially installed inside the extraction unit (30) and constitutes the extraction unit (30). However, components that allow the extraction unit (30) to move relative to the support leg (20) are also installed, which will be described herein. The hopper (29) is a part that collects the beverage extracted from the capsule (1) and delivers it to the cup. The hopper (29) is provided with a first hopper part (290) and a second hopper part (290') side by side so that the beverage extracted from each of the two capsules (1) can be collected.

[0115] The first hopper part (290) is located at a position corresponding to the lower part of one capsule (1), and the second hopper part (290') is located at a position corresponding to the lower part of the other capsule (1). The first hopper part (290) and the second hopper part (290') may be formed in an approximately circular shape when viewed in a plan view. The first hopper part (290) and the second hopper part (290') may be formed to be inclined. The inclination of the first hopper part (290) and the second hopper part (290') is such that the part where the first hopper part (290) and the second hopper part (290') are connected to each other is relatively lower in the direction of gravity than other parts.

[0116] The above hopper (29) has a discharge pipe (292). The discharge pipe (292) is a portion that delivers the extracted beverage dropped into the hopper (29) to the outside of the extraction unit (30). The discharge pipe (292) extends downward from the portion where the first hopper portion (290) and the second hopper portion (290') are connected. The beverage can be delivered to a cup located at the bottom of the extraction unit (30) through a discharge path (293) formed inside the discharge pipe (292).

[0117] The above hopper (29) may have a configuration for fastening to the housing (32) side. In the present embodiment, the hopper (29) is fastened to the lifting frame (27). For this purpose, the hopper (29) may have a first fastening portion (294) and a second fastening portion (294'). The first fastening portion (294) and the second fastening portion (294') are adjacent to a portion where the first hopper portion (290) and the second hopper portion (290') are connected to each other. The first fastening portion (294) and the second fastening portion (294') fasten the hopper (29) to the lifting frame (27). The first fastening portion (294) and the second fastening portion (294') may be fastened to a fastening rod (276) on the lifting frame (27) by screws.

[0118] In the illustrated embodiment, the driving source (28) is mounted on the hopper (29). As described above, the driving source (28) may be installed on the lifting frame (27) or a component fixed to the lifting frame (27). The hopper (29) may have a driving source installation portion (295). The driving source installation portion (295) is between the second fastening portion (294') and the hopper portion (290, 290'). A driving motor installation space (296) may be concavely formed in the driving source installation portion (295). A lead screw hole (297) is formed through the driving motor installation space (296). The lead screw (282) of the driving source (28) may be positioned through the lead screw hole (297). However, the drive source installation part (295) does not necessarily have to be present in the above hopper (29). There may be a configuration for installing the drive source (28) in the above lifting frame (27).

[0119] Figures 16 and 17 illustrate the configuration of the extraction unit (30). The skeleton of the extraction unit (30) may be formed by a housing (32). The housing (32) may have a frame (321). The frame (321) may be formed in an approximately ring shape. Components constituting the extraction unit (30) may be installed on the frame (321). A lower housing (322) is coupled to the lower portion of the frame (321).

[0120] The lower housing (322) may have a hollow hemispherical shape. The bottom of the lower housing (322) is open, and a residual water tray assembly to be described below may be mounted thereon. The lower housing (322) is provided with a number of penetration portions (322') corresponding to the number of support legs (20) through which the support legs (20) pass. The second support bar (23) and the second moving bar (25) of the support legs (20) pass through the penetration portions (322').

[0121] The lifting frame (27) is positioned and fixed inside the lower housing (322), and the hopper (29), driving source (28), etc. are positioned therein. An upper housing (323) can be installed on the frame (321).

[0122] The above frame (321), lower housing (322), and upper housing (323) may be provided separately from each other. Although not shown, at least one of the upper housing (323) and lower housing (322) may be provided as a single body with the frame (321).

[0123] The upper housing (323) may be formed so that the front is open. The upper housing (323) may serve to cover the interior of the extraction unit (30) when the cover (34) described below is opened.

[0124] There may be a cover (34) on the upper housing (323) or the frame (321) side. The cover (34) is configured to cover the upper housing (323). The cover (34) may form the exterior of the extraction unit (30) together with the lower housing (322). The cover (34) opens and closes the open front portion of the upper housing (323) to allow the insertion and removal of the capsule (1).

[0125] The above cover (34) is installed so as to be able to move up and down from the upper housing (323) and selectively opens and closes the open portion of the upper housing (323) as needed. A viewing window (344) may be provided on the cover (34). This allows the user to accurately recognize the situation inside the upper housing (323) through the viewing window (344).

[0126] In order to open and close the cover (34), the housing (32) has a cover opening and closing module (60). The cover opening and closing module (60) is positioned on the upper housing (323) and the cover (34) and serves to raise and lower the cover (34).

[0127] The above extraction unit (30) may have a frame member (33). The frame member (33) is installed inside the housing (32). The frame member (33) may be installed in the frame (321). Alternatively, the frame member (33) may be installed in the lower housing (322) or the upper housing (323). A configuration for extracting a beverage may be mounted on the frame member (33). A seating space in which a capsule (1) may be seated may be provided at the lower portion of the inside of the frame member (33). That is, a plurality of capsules (1) may be positioned on the frame member (33).

[0128] A tray (50) in which a capsule (1) is positioned can be positioned in the mounting space within the frame member (33). The capsule (1) can be positioned in the mounting space by passing through the open portion of the upper housing (323) and the open front of the frame member (33) while being mounted on the tray (50). In this case, the cover (34) is moved upward and in an open state. (See Fig. 16)

[0129] The above housing (32) has an elevating module (70). The elevating module (70) serves to elevate the phage cap that secures the capsule (1) when extracting a beverage. The phage cap can be elevated by the lifting force in the direction of gravity provided by the elevating module (70).

[0130] The housing (32) may have a power transmission module (90). The power transmission module (90) provides driving force for the operation of the lifting module (70). The power transmission module (90) can transmit the driving force of the motor (910) through a gear train installed in the gear housing (930) to thereby cause the lifting of the grip cap.

[0131] Next, the internal configuration of the base (10) will be described with reference to Fig. 18. Various components constituting the present invention may be installed inside the base (10). The base (10) is designed so that the center of gravity of the entire beverage device is located there.

[0132] For example, the base (10) may be configured to weigh about twice as much as the extraction unit (30). By doing so, the beverage device can be stably installed on the floor as a whole.

[0133] And, the base (10) is formed in a plate shape, and the support legs (20) are arranged on the base (10) at a predetermined interval, thereby making it possible for the extraction part (30) to be raised and lowered stably.

[0134] A control unit (80) is located in the space partitioned by the above control unit partition wall (122). The control unit (80) can perform control for the operation of the beverage device and control of the display (16) on the base (10), etc. The control unit (80) may be a printed circuit board on which various elements are mounted and a circuit is configured.

[0135] In the illustrated embodiment, the control unit (80) is positioned at the front portion inside the base (10). In other words, the control unit (80) is positioned along the front edge inside the base (10). The control unit partition wall (122) in the base body (12) partitions the inside of the base (10) into a space where the control unit (80) is installed and a space where the water supply unit (82) is installed. The control unit (80) may not be affected by the water supply unit (82) due to the control unit partition wall (122). For example, moisture or heat of the water supply unit (82) is blocked by the control unit partition wall (122) and is not transmitted to the control unit (80).

[0136] 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 have a water tank (84). The water tank (84) contains water required for extracting the beverage. The water tank (84) may be separated from the base (10) and filled with water.

[0137] For reference, when the beverage device of the present invention is fixed, an external water supply source can be connected to the water tank (84). Alternatively, the water tank (84) may be supplied directly from an external water supply source without being located in the base (10). In this case, the water supply unit (82) within the base (10) does not include the water tank (84).

[0138] The water tank (84) may be located at a position partitioned from the control unit (80). In the present embodiment, the water tank (84) is located in a space partitioned by the water tank partition wall (123). The position where the water tank (84) is placed is partitioned by the side wall (121), the water tank partition wall (123), and the control unit partition wall (122), and is also partitioned from a space where the water supply unit (82) is located. That is, the water tank (84) is located in a space partitioned by the water tank partition wall (123) and is also partitioned from other components of the water supply unit (82). This is to prevent water leakage from the water tank (84) or condensation on the outer surface of the water tank (84) from affecting the surroundings.

[0139] The shape of the water tank (84) is such that it can be brought in and out of the base (10) through the water tank inlet (121'). As can be seen in Fig. 19, the water tank (84) has a flat plate shape. The skeleton of the water tank (84) is formed by a water tank body (840). As can be seen in Figs. 19 and 20, the water tank body (840) has a flat hexahedral shape with a storage space (840') formed inside, and the storage space (840') is opened to a relatively large upper surface. At least one side of the water tank body (840) may be formed of a transparent member (840P). Alternatively, the entire water tank body (840) may be made of a transparent member (840P). It is preferable that the portion of the water tank body (840) exposed through the water tank inlet (121') is made of a transparent material (840P).

[0140] The open portion of the above storage space (840') is covered with a cover plate (841). The cover plate (841) has a shape corresponding to the open portion of the storage space (840'). When the cover plate (841) is separated from the water tank body (840), water can be quickly injected into the storage space (840'), and cleaning of the storage space (840') can also be facilitated.

[0141] An injection port (842) may be formed through the cover plate (841). The injection port (842) may be opened and closed by an injection port lid (843). By opening the injection port lid (843) while the cover plate (841) is placed on the water tank body (840), water may be injected into the storage space (840') through the injection port (842).

[0142] There is a discharge connector (844) on one side of the water tank body (840). Water in the storage space (840') can be discharged through the discharge connector (844). The discharge connector (844) is located relatively upper on one side of the water tank body (840). However, the discharge connector (844) can extend to the bottom of the storage space (840'). Alternatively, a separate hose (not shown) can be connected to the discharge connector (844) and extend to the bottom of the storage space (840'). By doing so, water at the bottom of the storage space (840') can be discharged.

[0143] On the other side of the water tank body (840), there is a locking member (845). The locking member (845) serves to fix the water tank (84) inside the base (10). To this end, the base (10) has a configuration in which the locking member (845) is coupled. Since the locking member (845) protrudes from the water tank body (840), when the water tank (84) is installed in the base (10), both sides of the water tank body (840) having the locking member (845) may have a predetermined gap with the water tank compartment wall (123), and thus, the water tank (84) may not be accurately inserted into the base (10) and may be twisted. To prevent this, an elastic member (846) is provided. The discharge connection member (844) and the elastic member (846) are on opposite outer surfaces of the transparent member (840P).

[0144] To prevent water leakage between the water tank body (840) and the cover plate (841), a seal (847) may be installed along the entrance of the storage space (840'). The seal (847) is configured to form a closed curve. The seal (847) is made of an elastic material and is compressed between the water tank body (840) and the cover plate (841) to prevent water leakage. The cross-section of the seal (847) is approximately similar to the letter '7', and a body groove (848) is formed in the mold body (840) and a cover groove (849) is formed in the cover plate (841) so that the seal (847) is seated.

[0145] A body step (848') may be formed along the body groove (848) to form one side of the body groove (848). A cover step (849') may be formed along the cover groove (849) to form one side of the cover groove (849). As can be seen in Fig. 21, one side of the cover step (849') and the seal (847) are simultaneously positioned in the body groove (848). The seal (847) and the body step (848') are simultaneously positioned in the cover groove (849). In this way, water leakage can be sufficiently prevented by the body step (848'), the cover step (849'), and the seal (847).

[0146] Inside the above base (10), there is a flow sensor (85). The flow sensor (85) can detect the amount of water flowing out of the water tank (84). The flow sensor (85) may be located adjacent to the water tank compartment wall (123). The flow sensor (85) and the discharge connector (844) may be connected.

[0147] Inside the base (10), there is a pump (86). The pump (86) sucks water from the water tank (84), pressurizes it, and sends it to the extraction unit (30). The pump (86) can provide a driving force for flowing water within the beverage device. The pump (86) receives water that has passed through the flow sensor (85). As can be seen in Fig. 18, the pump (86) is installed adjacent to one edge of the inside of the base (10). In addition, the pump (86) is located adjacent to the rear of the water tank (84).

[0148] The water pressurized by the pump (86) enters the boiler module (87). The boiler module (87) is installed adjacent to the edge corresponding to the rear of the base (10), particularly, one corner of the rear of the base (10). This is the position that is most distant from the control unit (80) or the water tank (84). By installing the boiler module (87) in this way, the influence of heat generated in the boiler module (87) being transferred to the water tank (84) or the control unit (80) can be minimized.

[0149] The above boiler module (87) has an exterior formed by a module housing (870) and a module cover (872). The module housing (870) and the module cover (872) can be made of a material having good insulation properties. Inside the module housing (870), there is a module space (870'). The module cover (872) shields the module space (870'). A plurality of communication holes (871) are formed on the lower part of the outer surface on both sides of the module housing (870). The communication holes (871) are positioned to correspond to the through holes (125) of the base body (12). Therefore, heat can be discharged to the outside through the communication holes (871) and the through holes (125).

[0150] A boiler (874) is installed inside the above module space (870'). The boiler (874) heats water. The boiler (874) has a heater, such as a sheath heater or a cartridge heater, inside, so that the water can be heated to a desired temperature. There may be various methods for heating the water in the boiler (874) other than the heaters mentioned above. For example, the water may be heated by installing a heat dissipation means in a pipe installed inside the boiler and through which water passes.

[0151] In the above module space (870'), the boiler (874) has a predetermined gap (A) with the module cover (872). (See FIG. 23) When the module cover (872) is installed in the base (10), it has a predetermined gap (B) with the base cover (13). In this way, there is a double gap (A, B) between the boiler (874) that generates a lot of heat and the display (16). Therefore, the influence of heat on the display (16) can be minimized by the gap (A, B).

[0152] Water from the boiler module (87) can be supplied to the extraction unit (30) through the supply valve (88). As can be seen in Fig. 18, the supply valve (88) is located at one edge of the base (10) adjacent to the boiler module (87). A three-way valve can be used as the supply valve (88). Accordingly, water from the supply valve (88) can be delivered to each of the two capsules (1). A first hose (881) and a second hose (882) are connected to the two paths exiting from the supply valve (88), respectively.

[0153] The first hose (881) and the second hose (882) may be extended to the extraction unit (30) through one of the support legs (20). In the present embodiment, the first hose (881) and the second hose (882) may pass through the interior of the support leg (20) located at the upper side with reference to FIG. 3 and at the rear side with reference to the base (10). Although the first hose (881) and the second hose (882) have a structure with good insulation properties, some heat from the water heated in the boiler module (87) may be transferred to the outside. However, since the leg at the rear side of the base (10) is relatively difficult for the user to access, even if the temperature of the corresponding support leg (20) increases, the impact on the user is relatively small.

[0154] For reference, wires (not shown) can pass through two support legs (20) located at the front of the base (10). The wires transmit power and control signals from the control unit (80), and are at a lower temperature than the first hose (881) or the second hose (882).

[0155] A check valve (89) may be provided between the pump (86) and the boiler module (87). The check valve (89) prevents water from flowing back into the boiler module (87). The check valve (89) is installed at the rear edge of the base (10).

[0156] Meanwhile, as shown in Fig. 18, when components are installed on the base body (12), they are mainly installed adjacent to the edge of the base body (12), i.e., the side wall (121), and relatively no components are placed in the center of the base body (12). This is to lower the center of gravity of the beverage device as much as possible by arranging the components inside the base (10).

[0157] The operation of the beverage device according to the present invention having the configuration described above will be described below.

[0158] In the present invention, it is described that the extraction part (30) is installed spaced apart from the base (10) by the support leg (20). At this time, the description of the part related to the assembly of the extraction part (30) is omitted, and the assembly of the fixed frame (26), the lifting frame (27), and the support leg (20) is described with reference to FIGS. 8 and 9.

[0159] The first support bar (22) is installed on the base (10) using the joint (228), and one side of the second support bar (23) is connected to the fixed frame (26). In this state, the second connecting plate (236) of the second support bar (23) is positioned between the first connecting plates (226) of the first support bar (22), so that the centers of the hinge holes (227) (237) coincide.

[0160] Then, the other side of the second moving bar (25), one side of which is connected to the lifting frame (27) by a hinge pin (254'), is connected to the first moving bar (24). More precisely, the first moving bar body (240) is connected to the first moving bar (24) and the first and second support bars (22, 23).

[0161] At this time, the first moving bar body (240) is simultaneously coupled to the hinge hole (252) of the second moving bar (25) and the hinge holes (227)(237) of the first and second support bars (22, 23). That is, the first hinge (242) of the first moving bar body (240) is coupled to the hinge holes (227)237) of the first and second support bars (22, 23), and the second hinge (243) of the first moving bar body (240) is coupled to the hinge hole (252) of the second moving bar (25).

[0162] Next, the first moving bar cover (241) is coupled to the first moving bar body (240). In this way, the assembly of the support leg (20) is completed by press-fitting and coupling the first moving bar cover (241) to the first moving bar body (240). Therefore, the assembly of the support leg (20) can be performed relatively easily.

[0163] In the present invention, the first support bar (22) and the second support bar (23) constituting the support leg (20) are connected to the fixed frame (26) and the base (10). Therefore, the base (10), the first support bar (22), the second support bar (23), and the fixed frame (26) form a fixed link mechanism to firmly support the extraction part (30).

[0164] The above support leg (20) changes the angle at which the first moving bar (24) and the second moving bar (25) are connected to each other by the driving force of the driving source (28). That is, when the extraction part (30) is operated by the driving force of the driving source (28), as can be seen in FIG. 6, the connecting angle of the first moving bar (24) and the second moving bar (25) changes.

[0165] Let us examine how the extraction part (30) moves by the driving force of the driving source (28) and how the connection angles of the first moving bar (24) and the second moving bar (25) change. The lead screw (282) rotated by the driving motor (280) rotates by the unidirectional rotation of the driving motor (280). The rotation of the lead screw (282) creates a linear movement of the lead screw (282) with respect to the fixed frame (26) in relation to the interlocking nut (265) installed on the fixed frame (26).

[0166] Accordingly, the lead screw (282) moves linearly in the longitudinal direction with respect to the fixed frame (26), and a linear movement of the drive motor (280) connected to the lead screw (282), the hopper (29) on which the drive motor (280) is installed, and the lifting frame (27) is created. Ultimately, this creates a movement of the housing (32) on which the lifting frame (27) is mounted.

[0167] The movement of the above housing (32) is performed with respect to the fixed frame (26), and the connecting bar (266) of the fixed frame (26) guides the lifting slot (271) of the lifting frame (27), so that the lifting frame (27) moves along a certain trajectory. Accordingly, the lifting motion of the lifting frame (27), i.e., the extraction part (30), occurs along a certain trajectory.

[0168] In (a) of Fig. 6, the extraction unit (30) is positioned relatively close to the base (10), and in (b) of Fig. 6, the extraction unit (30) is positioned relatively far from the base (10). In this way, when the extraction unit (30) is raised and lowered with respect to the base (10), even if the height of the cup placed on the base (10) varies, the extracted beverage can be accurately delivered to the cup.

[0169] Meanwhile, the cover (34) is raised relative to the housing (32) by driving the cover opening / closing module (60). When the cover (34) is raised relative to the housing (32) by driving the cover opening / closing module (60), the capsule (1) can be placed in the placement space located on the lower inner side of the frame member (33). The capsule (1) enters the placement space while being mounted on the tray (50).

[0170] When the capsule (1) is settled in the extraction unit (30), the cover (34) is lowered so that the upper housing (323) cannot be seen from the outside, and the capsule in the extraction unit (30) can be seen through the viewing window (344).

[0171] Next, the lifting module (70) drives the phage cap to extract a beverage from the capsule (1). With the capsule (1) gripped by the phage cap, water of a predetermined temperature delivered from the water supply unit (82) of the base (10) is supplied to the capsule (1), thereby allowing the beverage to be extracted. The beverage extracted from the capsule (1) falls into the first hopper portion (290) and the second hopper portion (290') of the hopper (29), and the beverage moves along the discharge path (293) of the discharge pipe (292) and enters a cup mounted on the base (10).

[0172] Meanwhile, the supply of water for extracting a beverage from the extraction unit (30) will be described. The water tank (84) can be inserted into the base (10) through the water tank inlet (121') of the base (10). The water tank (84) is fastened to the inside of the base (10) by the locking member (845). The locking member (845) is structured to be locked when pressed once and unlocked when pressed again. Therefore, when the user inserts the water tank (84) through the water tank inlet (121') and presses it, the locking is performed. When the water tank (84) is inserted into the base (10) and locked, pressing the water tank (844) inward unlocks the locking member (845), and the water tank (84) can protrude slightly outward due to the elastic force of the elastic member (846).

[0173] The water tank (84) can be taken out and water can be injected into the storage space (840'). The cover plate (841) can be separated to put water into the storage space (840'), or water can be injected through the inlet (842) of the cover plate (841). When the water tank (84) is filled with water, the water tank (84) is inserted into the water tank inlet (121') and the water tank (84) is mounted on the base (10). At this time, the amount of water inside the water tank (84) can be easily checked by the user because the transparent member (840P) is exposed through the water tank inlet (121').

[0174] When the operation unit (18) is operated to extract a beverage from the capsule (1), the pump (86) is driven. By driving the pump (86), the water in the water tank (84) passes through the flow meter (85) and the pump (86) and enters the boiler (874) of the boiler module (87). The water made at a predetermined temperature in the boiler (874) is delivered to the supply valve (80). The supply valve (80) selectively supplies water to the first hose (881) or the second hose (882). The first hose (881) or the second hose (882) is delivered to the extraction unit (30) through the inside of the first support bar (22) and the second support bar (23) of the support leg (20) located relatively at the rear of the base (10). The water delivered to the above extraction unit (30) is supplied to the capsule (1) and used for beverage extraction.

[0175] Meanwhile, in the present invention, each component is installed inside the base (10) at an edge of the base body (120), i.e., at a position adjacent to the side wall (121). Therefore, the stability of the base (10) in being placed on the ground is high.

[0176] And, inside the base (10), the boiler module (87) is installed at a corner at the rear of the base, and a boiler (874) that generates a lot of heat is located in a space formed by the module housing (870) and the module cover (872). And, there is a gap (A) between the module cover (872) and the boiler (874) and a gap (B) between the module cover (872) and the base cover (13), so that heat transferred to the display (16) between the base cover (13) and the base top plate (14) can be minimized.

[0177] Heat coming out of the above boiler (874) can be discharged to the outside through the communication hole (871) of the above module housing (870) and the through holes (125) formed in rows on both sides of the boiler mounting portion (124) of the above base body (12). The backflow of water between the above pump (86) and the boiler (874) can be blocked by the backflow prevention valve (89).

[0178] Although all components constituting the embodiments of the present invention have been described above as being combined or operating in combination, the present invention is not necessarily limited to these embodiments. That is, within the scope of the purpose of the present invention, all components may be selectively combined and operated one or more times. In addition, terms such as "include," "comprise," or "have" described above, unless specifically stated to the contrary, mean that the corresponding component may be inherent, and therefore should be interpreted as including other components rather than excluding other components. All terms, including technical or scientific terms, have the same meaning as generally understood by a person of ordinary skill in the art to which the present invention pertains, unless otherwise defined. Commonly used terms, such as terms defined in a dictionary, should be interpreted as being consistent with the contextual meaning of the related technology, and shall not be interpreted in an ideal or excessively formal sense, unless explicitly defined in the present invention.

[0179] For reference, the first moving bar (24) and the second moving bar (25) are not necessarily required in the above support leg (20). The first moving bar (24) and the second moving bar (25) operate in conjunction with the lifting and lowering of the extraction unit (30), thereby making it appear similar to the landing and takeoff operations of a spacecraft.

[0180] A driving source (28) is used to elevate the support leg (20) of the above-described extraction section (30), and in the illustrated embodiment, a driving motor (280) and a lead screw (282) are used. The lead screw (282) is linked with a linkage nut (265) in the fixed frame (26) to create a longitudinal linear movement of the lead screw (282). However, a rack gear and a pinion gear may also be used as the driving source (28). For example, a rack gear may be formed in the elevating frame (27), and a pinion gear may be installed in the fixed frame (26) to create an elevating movement of the elevating frame (27).
