Description

beverage extraction device

Embodiments are directed to providing a beverage extraction device.

A beverage can be extracted by supplying heated water with the beverage extraction object placed in the dripper. For example, liquid coffee (liquid coffee) can be extracted by supplying heated water to a dripper equipped with a filter while putting ground coffee beans into coffee powder. Coffee extracted in this way is called drip coffee, and in some cases, it may be called pourover coffee, filtered coffee, or brewed coffee.

A filter is placed to extract drip coffee, and the filter is cleaned before drip is performed by placing coffee powder on the filter. To clean the filter, washing water is supplied to pass through the filter. Washing water used to clean the filter may be disposed in the coffee container. Before performing drip by placing coffee powder in the filter, the washing water placed in the coffee receiver must be removed. If a process that requires removing the washing water is included between the washing using the washing water and the coffee drip process, the ease of use may be reduced.

In order to overcome these process disadvantages, a beverage extraction device in which the washing water is transferred to a washing water receiving space separate from the coffee receiving space may be considered.

A beverage extraction device according to one example may include a water tank that stores water and a dripper through which water flows from the water tank.

The arrangement diagram below the dripper along the first direction may include a beverage accommodating portion and a washing water accommodating portion disposed below the beverage accommodating portion along the first direction.

It may include a water outlet disposed between the beverage container and the washing water container, and an opening and closing part that opens and closes the water outlet.

A beverage extraction device according to one example may include a water tank that stores water and a dripper through which water flows from the water tank.

It may include a beverage accommodating portion disposed below the dripper along a first direction, and a washing water accommodating portion disposed below the beverage accommodating portion along the first direction.

It may include a deformable water outlet disposed between the beverage container and the washing water container.

FIG. 1 is a diagram showing a beverage extraction device 1 according to an example, and FIG. 2 is a diagram conceptually showing the beverage extraction device 1 according to an example.

Referring to Figures 1 and 2, the beverage extraction device 1 according to one example is a device that extracts a beverage by dispensing heated water toward the dripper 2. For example, it may be a device for extracting a coffee beverage (hereinafter referred to as 'coffee') by pouring heated water into an extraction object, for example, coffee powder (C), contained in the dripper 2.

As an example for this, the beverage extraction device 1 includes a water tank 20 in which water is stored, a heater 11 for heating water, and water for pouring water into the dripper 2 in which coffee powder (C) can be contained. It may include a distribution module (5).

The dripper 2 has a structure in which the width or diameter narrows toward the bottom, and a filter 4 can be placed inside. Coffee powder (C) may be contained inside the filter (4). A server 10 that stores extracted coffee may be placed below the dripper 2.

The water tank 20 stores water and can be detachably mounted on the main body 6. The user can separate the water tank 20 and fill it with water or clean the inside of the water tank 20.

The heater 11 is disposed between the water tank 20 and the water distribution module 5 and can heat water supplied from the water tank 20. The heater 11 can heat water to a set target temperature. The operating time and operating point of the heater 11 may be controlled by the control unit 15. The target temperature heated by the heater 11 may vary depending on the extraction object, for example, the type of coffee powder (C), extraction time, etc.

The water distribution module 5 may discharge water from a plurality of positions toward the dripper 2. As water is discharged from a plurality of positions by the water distribution module 5, water is poured into the coffee powder C contained in the dripper 2, and coffee is extracted. The extracted coffee is stored in the server 10.

The beverage extraction device 1 according to one example may further include a pump 12 that provides pressure to direct the water stored in the water tank 20 toward the water distribution module 5 . The control unit 15 can control at least one of the water discharge speed and water discharge time at which water is discharged from the water distribution module 5 by controlling the pump 12.

The beverage extraction device 1 according to one example may further include a dripper holder 31 on which the dripper 2 is mounted, and a beverage container holder 32 on which the server 10 is mounted. The dripper holder 31 may have a structure that can move up and down. The user can adjust the height of the dripper 2 according to the size of the server 10 or the dripper 2 by adjusting the height of the dripper holder 31. A container detection sensor 13 that detects whether the server 10 is mounted on the beverage container holder 32 may be disposed. The control unit 15 may determine whether to operate the pump 12 based on the detection result of the container detection sensor 13.

The beverage extraction device 1 according to one example may further include a flow rate sensor 14 for detecting the flow rate supplied from the water tank 20. The flow sensor 14 may be placed between the water tank 20 and the heater 11. However, the arrangement of the flow sensor 14 is not limited to this, and may be changed in various ways as long as it is positioned to detect the amount of water supplied.

The water supplied from the water tank 20 may be heated by the heater 11 and supplied to the water distribution module 5. The water distribution module 5 may include a first piping portion 17 and a second piping portion 18 capable of supplying water toward the dripper 2. The first piping unit 17 may be arranged to supply water to the central area of the water outlet unit 19. The first pipe portion 17 may provide a first flow path through which water moves toward the center area of the water outlet portion 19. Water moving through the first flow path may be supplied to the coffee powder (C) contained in the dripper (2). According to one example, the first piping unit 17 may be singular. However, the number of first pipe parts 17 is not limited to this and may be plural.

The second piping unit 18 may be arranged to supply water to the outer area of the water outlet unit 19. For example, there may be a plurality of second pipe parts 18. Each of the plurality of second pipe parts 18 can supply water to the outer area of the water outlet part 19 at regular intervals. The second piping unit 18 may provide a second flow path through which water moves toward the outer area of the water outlet unit 19. Water moving through the second flow path may be supplied to the filter (4) of the dripper (2). The second flow path may be a flow path through which washing water for rinsing the filter 4 moves. The number and connection structure of the second piping units 18 according to one example are illustrative and are not necessarily limited thereto.

The first piping part 17 and the second piping part 18 may be connected by a valve 16. The valve 16 may be a 3-way valve. By means of the valve 16, heated water can be selectively supplied to the first piping unit 17 or the second piping unit 18. For example, in the cleaning step for cleaning the filter 4, the valve 16 opens the second piping part 18 so that water is supplied through the second piping part 18, and the first piping part 17 can be blocked. The valve 16 may open the first piping unit 17 and block the second piping unit 18 so that water is supplied through the first piping unit 17 in the drip stage for coffee extraction.

The water that has passed through the second piping unit 18 can be received in the server 10 after cleaning the filter 4. Hereinafter, the water stored in the server 10 after passing through the second piping unit 18 and washing the filter 4 is referred to as washing water (W ₂ : see FIG. 8). Additionally, the water that has passed through the first pipe portion 17 may pass through the coffee powder (C), be extracted as coffee, and then be accommodated in the server (10). Hereinafter, the water stored in the server 10 after passing the coffee powder C through the first pipe 17 is referred to as coffee W ₁ (see FIG. 8). Since both the washing water (W ₂ ) and the coffee (W ₁ ) can be accommodated in the server 10, the washing water (W ₂ ) and the coffee (W ₁ ) must be stored separately. Additionally, the washing water (W ₂ ) and the coffee (W ₁ ) must be discharged from the server 10 sequentially. Hereinafter, the server 10 that separates and stores the washing water (W ₂ ) and the coffee (W ₁ ) and discharges them separately will be described.

Figure 3 is a perspective view of a server according to an example. Figure 4 is an exploded perspective view of a server according to an example. FIG. 5 is a cross-sectional view of the server shown in FIG. 3 taken along line A-A. Figure 6 is an enlarged view of a cross-sectional view according to an example. Figure 7 is an enlarged view of a cross-sectional view according to an example. Figure 8 is a cross-sectional view of a server according to an example. Figure 9 is an exploded perspective view of a server according to an example.

Referring to FIGS. 3 to 8, the server 10 according to one example includes a beverage container 110 in which coffee (W ₁ ) is accommodated, a washing water container 120 in which washing water (W ₂ ) is accommodated, and a beverage container. A water outlet 140 disposed between the unit 110 and the washing water receiving part 120 and an opening and closing unit 160 that opens and closes the water outlet 140 may be included.

The beverage container 110 is a receiving member that can accommodate coffee (W ₁ ). As an example, the beverage container 110 may be disposed in the lower portion of the dripper 2 where the coffee powder C and the filter 4 are disposed along the first direction (Z direction). Accordingly, the washing water (W ₂ ) that has passed through the filter 4 may be accommodated in the beverage container 110 along the first direction (Z direction). Additionally, the coffee (W ₁ ) that has passed through the coffee powder (C) may be accommodated in the beverage container 110 along the first direction (Z direction). The beverage container 110 according to one example may include an accommodating space capable of accommodating coffee (W ₁ ) and washing water (W ₂ ). Additionally, the beverage container 110 may include any material that may include coffee (W ₁ ) and washing water (W ₂ ).

The washing water receiving portion 120 is a receiving member that can accommodate washing water (W ₂ ). As an example, the washing water container 120 may be disposed below the beverage container 110 along the first direction (Z direction). Accordingly, the washing water (W ₂ ) that has passed through the beverage container 110 may be accommodated in the washing water container 120 along the first direction (Z direction). The washing water receiving unit 120 according to one example may include a receiving space capable of containing washing water (W ₂ ). Additionally, the washing water receiving portion 120 may include any material that can contain washing water (W ₂ ).

As an example, the washing water accommodating part 120 may be arranged to be separable from the beverage accommodating part 110. For example, when the washing water (W ₂ ) contained in the washing water accommodating part 120 needs to be discharged, the washing water accommodating part 120 may be separated from the beverage accommodating part 110. Accordingly, the washing water (W ₂ ) contained in the washing water receiving portion 120 may be discharged to the outside. However, the present disclosure is not limited to this, and when a separate opening for discharging the washing water (W ₂ ) to the outside is disposed, the washing water receiving portion 120 and the beverage receiving portion 110 may be formed integrally.

The water outlet 140 is an opening disposed between the beverage container 110 and the washing water container 120. As an example, the water outlet 140 may be an opening having a predetermined diameter. Additionally, the water outlet 140 may be disposed at the lower portion of the beverage container 110. Accordingly, the water outlet 140 may form a flow path through which the washing water (W ₂ ) contained in the beverage container 110 can pass. As described above, coffee (W ₁ ) and washing water (W ₂ ) must be stored separately and discharged separately. To this end, the water outlet 140 may be selectively opened when the washing water (W ₂ ) moves from the beverage container 110 to the washing water container 120. Additionally, the water outlet 140 may be selectively closed when coffee (W ₁ ) is accommodated in the beverage container 110 .

The opening and closing unit 160 can selectively open and close the water outlet 140. As an example, the opening and closing part 160 may be arranged to rise or fall along the first direction (Z direction) to open or close the water outlet 140. For example, the opening and closing unit 160 may include a flat opening and closing plate 1601 and a guide portion 1602 disposed on one surface of the opening and closing plate 1601.

The opening and closing plate 1601 according to one example may have an area exceeding the diameter of the water outlet 140. When the opening and closing plate 1601 is disposed on the upper part of the water outlet 140, the water outlet 140 can be closed. Additionally, when the opening and closing plate 1601 rises along the first direction (Z direction) and is arranged to be spaced apart from the water outlet 140, the water outlet 140 may be opened.

The guide unit 1602 according to one example may extend along the first direction (Z direction). The guide unit 1602 is arranged to be inserted into the water outlet 140 and can rise or fall along the first direction (Z direction). As the guide unit 1602 rises or falls along the first direction (Z direction), the opening and closing plate 1601 arranged so that one surface is fixed to one end of the guide unit 1602 also moves in the first direction (Z direction). It can rise or fall accordingly. The diameter of the guide portion 1602 may be smaller than the diameter of the water outlet 140. Accordingly, the guide unit 1602 can guide the movement of the opening and closing plate 1601 without blocking the water outlet 140.

The first sealing part 163 may be disposed between the opening and closing part 160 and the inclined part 170, which will be described later. As an example, the first sealing part 163 may include an elastic member having elastic force. For example, the first sealing portion 163 may include silicon, but the present disclosure is not limited thereto. The first sealing part 163 according to one example may be arranged to surround the opening and closing plate 1601 included in the opening and closing unit 160. Accordingly, the first sealing part 163 may be disposed between the opening and closing plate 1601 and the inclined part 170. As the first sealing part 163 is disposed between the opening and closing part 160 and the inclined part 170, the beverage receiving part 110 and the washing water receiving part 120 can be separated. Accordingly, it is possible to prevent the coffee (W ₁ ) contained in the beverage container 110 from flowing into the washing water container 120 .

The second sealing part 164 may be disposed between the opening and closing part 160 and the water outlet 140. As an example, the second sealing part 164 may include an elastic member having elastic force. For example, the second sealing portion 164 may include silicon, but the present disclosure is not limited thereto. The second sealing part 164 according to one example may be arranged to extend along the circumference of the guide part 1602 included in the opening and closing part 160. Accordingly, the second sealing part 164 may be disposed between the guide part 1602 and the water outlet 140. As the second sealing part 164 is disposed between the guide part 1602 and the water outlet 140, the beverage receiving part 110 and the washing water receiving part 120 can be separated. Accordingly, it is possible to prevent the coffee (W ₁ ) contained in the beverage container 110 from flowing into the washing water container 120 .

According to one example, one or more of the first sealing part 163 and the second sealing part 164 may be disposed. The first sealing part 163 and the second sealing part 164 may include the same or different materials. Additionally, the first sealing part 163 and the second sealing part 164 may be formed integrally or separately.

The inclined portion 170 may be disposed between the beverage container 110 and the washing water container 120 and may be a boundary portion that distinguishes the beverage container 110 and the washing water container 120. As an example, the inclined portion 170 is on the same plane as the water outlet 140. For example, a predetermined inclination angle (α) may be provided between one plane (XY plane) perpendicular to the first direction (Z direction). As an example, the predetermined inclination angle (α) may be 1 degree or more and less than 10 degrees, but the present disclosure is not limited thereto. As the inclined portion 170 has a predetermined inclination angle α between the water outlet 140 and one plane (XY plane), the washing water (W ₂ ) contained in the beverage receiving portion 110 flows toward the water outlet 140. You can move.

The inclined portion 170 according to one example may include a material with high thermal conductivity, for example, a stainless steel material with high thermal conductivity. Accordingly, heat is conducted from the washing water (W ₂ ) accommodated in the washing water receiving portion 120 to the coffee (W ₁ ) accommodated in the beverage receiving portion 110, thereby performing a warming function for the coffee (W ₁ ). As an example, the inclined portion 170 may be formed integrally with the beverage container 110 to form the lower portion of the beverage container 110. However, the present disclosure is not limited to this, and the inclined portion 170 may be formed separately from the beverage container 110 and may be disposed at the lower portion of the beverage container 110.

The opening/closing module 180 may open or close the opening/closing unit 160 by applying pressure along a first direction (Z direction) to one end of the opening/closing unit 160 . The opening/closing module 180 according to one example may include a shaft 181 extending in one direction and a cam 182 that is fixed to the shaft 181 and is movable together with the shaft 181.

The shaft 181 extends along a second direction (Y direction) perpendicular to the first direction (Z direction). At this time, the shaft 181 may move along the second direction (Y direction) by receiving pressure from the manipulation unit 190, which will be described later. As an example, one end 1810 of the shaft 181 may be supported by the shaft support 1831 and guided to move along the second direction (Y direction). Additionally, the other end 1811 of the shaft 181 may be supported by the shaft support 1832 and guided to move along the second direction (Y direction). The movement limiter 185 according to one example may be disposed between one end 1810 and the other end 1811 of the shaft 181. The movement limiter 185 may extend along the first direction (Z direction). When the shaft 181 moves along the second direction (Y direction) over a predetermined range, the movement limiting part 185 may be supported by the shaft support part 1832. Accordingly, the shaft 181 can move left and right along the second direction (Y direction) within a predetermined range.

As the cam 182 moves in the second direction (Y direction), pressure may be applied to one end of the opening/closing unit 160 along the first direction (Z direction). For example, the cam 182 is arranged to be fixed to the shaft 181 and can move along the second direction (Y direction) together with the shaft 181. The cam 182 according to one example may include a guide inclined surface 1820 having a predetermined inclined angle. The slide unit 166 according to one example is supported on the guide inclined surface 1820 provided on the cam 182 and may rise or fall along the first direction (Z direction). At this time, the slide part 166 may be arranged to be fixed to one end of the opening and closing part 160. Accordingly, pressure is applied to one end of the opening and closing part 160, so that the opening and closing part 160 can rise or fall along the first direction (Z direction). The slide part 166 according to one example may have a cylindrical shape that can accommodate the cam 182. The upper surface portion 1661 of the slide portion 166 may be arranged to be fixed to one end of the opening and closing portion 160, for example, to one end of the guide portion 1602. A through hole into which the shaft 181 can be inserted may be disposed in the side portion 1662 of the slide portion 166. At this time, the guide inclined surface 1820 provided on the cam 182 may or may not be supported on the side 1662 of the slide unit 166 as the shaft 181 moves along the second direction (Y direction). .

The manipulation unit 190 may apply pressure to the shaft 181 so that the shaft 181 moves along the second direction (Y direction). As an example, one end 191 of the manipulation unit 190 may receive pressure from the user along the second direction (Y direction). Additionally, the other end 192 of the manipulation unit 190 may be arranged to be fixed to the shaft 181. Accordingly, when the manipulation unit 190 moves along the second direction (Y direction) by receiving pressure from the user, the shaft 181 may also move along the second direction (Y direction).

The first elastic part 165 may apply a restoring force to the opening and closing part 160 along the first direction (Z direction). As an example, the first elastic part 165 may be a torsion spring disposed in the guide part 1602, but the present disclosure is not limited thereto. For example, when the opening and closing part 160 rises along the first direction (Z direction) to open the opening and closing part 160, the first elastic part 165 is connected to the upper surface of the opening and closing plate 1601 and the slide part 166. It may be compressed along the first direction (Z direction) between the parts 1661. Additionally, when the pressure applied to the first elastic portion 165 is released, the first elastic portion 165 may expand along the first direction (Z direction) due to the restoring force of the first elastic portion 165. When the first elastic portion 165 is expanded along the first direction (Z direction) between the opening and closing plate 1601 and the upper surface portion 1661 of the slide portion 166, the opening and closing portion 160 is expanded in the first direction (Z direction). The opening/closing unit 160 may be closed by descending along the direction (direction).

The second elastic portion 184 may apply a restoring force to the shaft 181 along the second direction (Y direction). As an example, the second elastic part 184 may be a torsion spring disposed on the shaft 181, but the present disclosure is not limited thereto. For example, when pressure is applied to the manipulation unit 190 and the manipulation unit 190 moves along the second direction (Y direction), the second elastic portion 184 arranged to be fixed to the shaft 181 is the second elastic portion 184. Can be compressed along a direction (Y direction). Additionally, when the pressure applied to the second elastic portion 184 is released, the second elastic portion 184 may expand along the second direction (Y direction) due to the restoring force of the second elastic portion 184. When the second elastic portion 184 is expanded along the second direction (Y direction), the shaft 181 may also be moved to the position before applying pressure along the second direction (Y direction), for example, to the left. there is.

As described above, the washing water (W ₂ ) is moved to the washing water receiving portion 120 according to the opening and closing of the water outlet 140, and the beverage receiving portion 110 and the washing water receiving portion 120 are spatially separated from each other. Coffee (W ₁ ) can be accommodated in the receiving portion 110 .

According to one example, after the washing water (W ₂ ) for cleaning the filter 4 is accommodated in the beverage receiving portion 110, the user applies pressure to the operation unit 190 to force the washing water (W ₂ ) into the washing water receiving portion 120. ) can be moved to . As an example, as shown in FIG. 7, when pressure is applied to the operating unit 190 to the right along the second direction (Y direction), the operating unit 190 moves to the right along the second direction (Y direction). You can. As the manipulation unit 190 moves to the right along the second direction (Y direction), the shaft 181 fixed to the manipulation unit 190 may also move along the second direction (Y direction). When the guide inclined surface 1820 is supported on the side portion 1662 of the slide portion 166 as the shaft 181 moves along the second direction (Y direction), the slide portion 166 moves in the first direction (Z direction). ) can rise along. At this time, the opening and closing part 160, one end of which is supported on the slide part 166, may also rise along the first direction (Z direction). As the opening and closing part 160 rises along the first direction (Z direction), the water outlet 140 may be opened. Accordingly, the washing water (W ₂ ) accommodated in the beverage container 110 may move to the washing water container 120 through the water outlet 140.

After the washing water (W ₂ ) moves to the washing water receiving part 120 , the coffee (W ₁ ) may be received in the beverage receiving part 110 through a drip process. At this time, the user can release the pressure applied to the operating unit 190 to separate the coffee (W ₁ ) accommodated in the beverage container 110 and the washing water (W ₂ ) accommodated in the washing water container 120. As an example, as shown in FIG. 6, when the pressure applied to the operating unit 190 is released, a restoring force is applied by the second elastic part 184 so that the shaft 181 moves in the second direction (Y direction). You can move to the left. When the support of the guide inclined surface 1820 and the side portion 1662 of the slide portion 166 is released as the shaft 181 moves along the second direction (Y direction), the restoring force is generated by the first elastic portion 165. With this application, the slide unit 166 can descend along the first direction (Z direction). At this time, the opening and closing part 160, one end of which is supported on the slide part 166, may also descend along the first direction (Z direction). As the opening/closing unit 160 descends along the first direction (Z direction), the water outlet 140 may be closed.

According to one example, as the opening and closing part 160 descends along the first direction (Z direction), when the water outlet 140 is closed, the coffee (W ₁ ) contained in the beverage container 110 as shown in FIG. 8 ) and the washing water (W ₂ ) contained in the washing water receiving portion 120 may be stored separately. Washing water (W ₂ ) and coffee (W ₁ ) may be accommodated in the beverage receiving portion 110 and the washing water receiving portion 120, respectively, bordering the inclined portion 170. At this time, the heat (H) remaining in the washing water (W ₂ ) accommodated in the washing water receiving portion 120 may be conducted to the coffee (W ₁ ) through the inclined portion 170. Accordingly, the warming effect of coffee (W ₁ ) may be improved.

Referring to FIG. 9 , the beverage container 110 according to an example may include an opening through which coffee (W ₁ ) and washing water (W ₂ ) can pass. At this time, the opening blocking unit 130 may be disposed in the opening of the beverage container 110 to selectively block the opening. The opening blocking unit 130 according to an example includes a blocking unit main body 131, a locking unit 132 extending along the first direction (Z direction), a groove 133 provided in the beverage container 110, and a groove ( It may include an insertion portion 134 that is inserted into the 133).

The blocking unit body 131 is a blocking member that can block the opening of the beverage receiving unit 110. As an example, the blocking unit body 131 may be provided in a rigid body shape. The locking unit 132 may be disposed on the lower surface of the blocking unit body 131.

FIG. 12 is a cross-sectional view of the server shown in FIG. 10 taken along line B-B. Figure 13 is an enlarged view of a cross-sectional view according to an example. Figure 14 is an enlarged view of a cross-sectional view according to an example.

10 to 14, the server 10' according to one example includes a first case (C) including a beverage container 210, a washing water container 220, a water outlet 240, and an opening/closing portion 260. ₁ ) and a second case (C ₂ ) that accommodates the first case (C ₁ ). As an example, the first case (C ₁ ) including the beverage container 210, the washing water container 220, the water outlet 240, and the opening/closing portion 260 may be formed as one piece. The first case (C ₁ ) according to one example may have elasticity that can be deformed by a predetermined pressure. For example, the first case C ₁ may include a silicon material, but the present disclosure is not limited thereto.

The second case (C ₂ ) according to one example may be provided with an accommodating space for accommodating the first case (C ₁ ). The second case C ₂ may be formed of a rigid body that does not deform under a predetermined pressure. Accordingly, the second case C ₂ can form the exterior of the server 10'. As an example, the first case (C ₁ ) may be arranged to be separable from the second case (C ₂ ). For example, when the washing water (W ₂ ) contained in the first case (C ₁ ) needs to be discharged, the first case (C ₁ ) may be separated from the second case (C ₂ ). Accordingly, the washing water (W ₂ ) contained in the first case (C ₁ ) may be discharged to the outside. However, the present disclosure is not limited to this, and when a separate opening for discharging the washing water (W ₂ ) to the outside is disposed, the first case (C ₁ ) and the second case (C ₂ ) may be formed integrally. there is.

As described above, the first case (C ₁ ) may include a beverage receiving portion 210, a washing water receiving portion 220, a water outlet 240, and an opening/closing portion 260. Excluding the opening and closing portion 260, the beverage receiving portion 210, the washing water receiving portion 220, and the water outlet are substantially similar to the beverage receiving portion 110, the washing water receiving portion 120, and the water outlet 140 shown in FIGS. 3 to 8. Since it is the same, the explanation is omitted here.

The opening and closing unit 260 can selectively open and close the water outlet 240. As an example, the opening and closing part 260 may be arranged to rise or fall along the first direction (Z direction) to open or close the water outlet 240. For example, the opening and closing portion 260 includes a flat opening and closing plate 261, a guide portion 262 disposed on one side of the opening and closing plate 261, and a step disposed between the opening and closing plate 261 and the guide portion 262. It may include a support portion 263.

The opening and closing plate 261 according to one example may have an area exceeding the diameter of the water outlet 240. When the opening and closing plate 261 is disposed on the upper part of the water outlet 240, the water outlet 240 can be closed. Additionally, when the opening and closing plate 261 rises along the first direction (Z direction) and is arranged to be spaced apart from the water outlet 240, the water outlet 240 may be opened.

The guide unit 262 according to one example may extend along the first direction (Z direction). The guide part 262 is arranged to be inserted into the water outlet 240 and can rise or fall along the first direction (Z direction). The diameter of the guide portion 262 may be smaller than the diameter of the water outlet 240. Accordingly, the guide unit 262 can guide the movement of the opening and closing plate 261 without blocking the water outlet 240.

The step support portion 263 according to one example may apply pressure to the inclined portion 270 by contacting a pressure applying portion 271 provided at one end of the inclined portion 270, which will be described later. For example, the step support portion 263 may have a step surface extending along the first direction (Z direction). At this time, the step surface provided on the step support portion 263 may be arranged to face the pressure applying portion 271. Depending on the pressure applied to the manipulation unit 290, which will be described later, the step surface provided in the step support portion 263 and the pressure application portion 271 may be supported in contact with each other, or may be arranged to be spaced apart from each other.

The inclined portion 270 may be disposed between the beverage container 210 and the washing water container 220 and may be a boundary portion that distinguishes the beverage container 210 and the washing water container 220. As an example, the inclined portion 270 may be formed integrally with the first case (C ₁ ) including the beverage accommodating portion 210 and the washing water accommodating portion 220. Additionally, the inclined portion 270 may include a material having elasticity, for example, silicon. Accordingly, the inclined portion 270 may be deformed when a predetermined pressure is applied or restored to its original state when the predetermined pressure is released.

The manipulation unit 290 may apply pressure to the inclined portion 270 so that the shape of the inclined portion 270 is deformed. As an example, the manipulation unit 290 may be formed integrally with the first case C ₁ including the inclined portion 270 . At this time, the manipulation unit 290 may be arranged to be inserted into the through hole 291 provided in the second case C ₂ and exposed to the outside. Accordingly, the user can apply pressure to the externally exposed operation unit 290 along the second direction (Y direction). As an example, one end of the manipulation unit 290 may receive pressure from the user along the second direction (Y direction). Additionally, the other end of the manipulation unit 290 may be arranged to be fixed to the inclined part 270. Accordingly, when the manipulation unit 290 receives pressure from the user along the second direction (Y direction), the inclined part 270 may also move along the second direction (Y direction). When the inclined portion 270 moves along the second direction (Y direction), the step surface provided on the step support portion 263 and the pressure applying portion 271 provided at one end of the inclined portion 270 contact each other. This can be supported. At this time, when the pressure applicator 271 receives pressure along the second direction (Y direction), the shape of the inclined part 270 may be deformed. Accordingly, a predetermined gap M is formed between the opening and closing plate 261 and the inclined portion 270, so that the washing water (W ₂ ) contained in the beverage container 210 can move to the washing water container 220.

The elastic portion 265 may apply a restoring force to the inclined portion 270 along the second direction (Y direction). As an example, the elastic part 265 may be an elastic spring disposed between the other end of the inclined part 270 and the other end of the manipulation unit 290. For example, the elastic portion 265 may be a silicon spring formed integrally with the inclined portion 270, but the present disclosure is not limited thereto. According to one example, when pressure is applied to the manipulation unit 290 along the second direction (Y direction), the elastic part 265 may be compressed and deformed between the inclined part 270 and the manipulation unit 290. Additionally, when the pressure applied to the elastic portion 265 is released, the shape of the elastic portion 265 may be restored to its original state by the restoring force of the elastic portion 265. When the shape of the elastic portion 265 is restored to its original state, the shape of the inclined portion 270 is restored, and the step surface provided in the stepped support portion 263 and the pressure applying portion provided at one end of the inclined portion 270 ( 271) can be separated from each other. Accordingly, the predetermined gap M disappears between the opening and closing plate 261 and the inclined portion 270, so that the beverage container 210 and the washing water container 220 can be spatially separated from each other.

As described above, the washing water (W ₂ ) is moved to the washing water receiving portion 220 according to the opening and closing of the water outlet 240, and the beverage receiving portion 210 and the washing water receiving portion 220 are spatially separated from each other, and the beverage Coffee (W ₁ ) can be accommodated in the receiving portion 210 .

According to one example, after the washing water (W ₂ ) for cleaning the filter 4 is accommodated in the beverage receiving portion 210, the user applies pressure to the operation unit 290 to force the washing water (W ₂ ) into the washing water receiving portion 220. ) can be moved to . As an example, as shown in FIG. 14, when pressure is applied to the manipulation unit 290 to the left along the second direction (Y direction), the manipulation unit 290 moves to the left along the second direction (Y direction). You can. As the manipulation unit 290 moves to the left along the second direction (Y direction), the inclined portion 270 fixed to the manipulation unit 290 may also move along the second direction (Y direction). As the inclined portion 270 moves along the second direction (Y direction), the step surface provided on the step support portion 263 and the pressure applying portion 271 provided at one end of the inclined portion 270 contact each other. It can be supported. At this time, when the pressure applicator 271 receives pressure along the second direction (Y direction), the shape of the inclined part 270 may be deformed. Accordingly, a predetermined gap M is formed between the opening and closing plate 261 and the inclined portion 270, so that the washing water (W ₂ ) contained in the beverage container 210 can move to the washing water container 220.

After the washing water (W ₂ ) moves to the washing water receiving part 220 , the coffee (W ₁ ) may be received in the beverage receiving part 210 through a drip process. At this time, the user can release the pressure applied to the operating unit 290 to separate the coffee (W ₁ ) accommodated in the beverage container 210 and the washing water (W ₂ ) accommodated in the washing water container 220. As an example, as shown in FIG. 13, when the pressure applied to the manipulation unit 290 is released, a restoring force is applied by the elastic unit 265 so that the inclined unit 270 moves along the second direction (Y direction). You can move to the right. As the inclined portion 270 moves along the second direction (Y direction), the shape of the inclined portion 270 is restored, and the step surface provided on the step support portion 263 and the inclined portion 270 are provided at one end. The pressure applicators 271 may be spaced apart from each other. Accordingly, the predetermined gap M between the opening and closing plate 261 and the inclined portion 270 disappears, and the water outlet 240 can be closed. As the water outlet 240 is closed, the beverage container 210 and the washing water container 220 may be spatially separated from each other.

The first case D ₁ according to an example may have elasticity that can be deformed by a predetermined pressure. For example, the first case D ₁ may include a silicon material, but the present disclosure is not limited thereto.

The second case (D ₂ ) according to one example may be provided with an accommodating space for accommodating the first case (D ₁ ). The second case D ₂ may be formed of a rigid body that does not deform under a predetermined pressure. Accordingly, the second case D ₂ can form the exterior of the server 10''. As an example, the first case (D ₁ ) may be arranged to be separable from the second case (D ₂ ). For example, when the washing water (W ₂ ) contained in the first case (D ₁ ) needs to be discharged, the first case (D ₁ ) may be separated from the second case (D ₂ ). Accordingly, the washing water (W ₂ ) contained in the first case (D ₁ ) may be discharged to the outside. However, the present disclosure is not limited to this, and when a separate opening for discharging the washing water (W ₂ ) to the outside is disposed, the first case (D ₁ ) and the second case (D ₂ ) may be formed integrally. there is.
