Patent Description:
A beverage extracting device is a device for extracting a beverage such as coffee, green tea, or the like to provide the beverage to a user.

To this end, a beverage extracting device may use a beverage capsule in which beverage powder such as coffee, green tea, or the like is stored.

In a beverage extracting device using a beverage capsule, hot water at a predetermined pressure is supplied from a hot water source to a beverage capsule, and thus, the hot water at a predetermined pressure is mixed with the beverage powder.

In addition, as described above, when the hot water at a predetermined pressure is mixed with the beverage powder, a beverage is produced. In other words, a beverage can be extracted from a beverage capsule.

As described above, a beverage is extracted from a beverage extracting device to be provided to a user.

Generally, in a beverage extracting device, a beverage capsule is perforated using a separate punching member, or the like. In this case, after a beverage capsule is perforated by a punching member, the beverage capsule remains located inside the beverage extracting device.

Hereinafter, with reference to <FIG>, the beverage extracting device <NUM> will be described.

<FIG> is an exploded perspective view of a beverage extracting device according to an exemplary embodiment of the invention, <FIG> is a perspective view illustrating a state in which an opening and closing part of a beverage extracting device according to an exemplary embodiment of the invention is open, <FIG> is a perspective view illustrating a state in which an opening and closing part of a beverage extracting device according to an exemplary embodiment of the invention is closing, and <FIG> is a perspective view illustrating a state in which an opening and closing part of a beverage extracting device according to an exemplary embodiment of the invention is closed.

With reference to <FIG>, a beverage extracting device <NUM> according to an exemplary embodiment of the invention includes an extracting part <NUM>, an opening and closing part <NUM>, a link part <NUM>, and a perforating part <NUM>.

First, the beverage extracting device <NUM> according to an exemplary embodiment of the invention will be schematically described.

An installing space MS is provided in the extracting part <NUM>, and a beverage capsule C may be installed in the installing space MS. The opening and closing part <NUM> is connected to the extracting part <NUM> so as to open or seal the installing space MS.

For example, the opening and closing part <NUM> is connected to the extracting part <NUM> to be rotated. When the opening and closing part <NUM> is closed, the installing space MS may be sealed. When the opening and closing part <NUM> is open, the installing space MS may be open.

The beverage capsule C is installed in the installing space MS, and high-pressure hot water may be provided for the beverage capsule C through the opening and closing part <NUM>, while the installing space MS is sealed.

When the opening and closing part <NUM> is closed, the beverage capsule C is perforated by the perforating part <NUM>, and thus, a beverage may be extracted from the beverage capsule C.

To perforate the beverage capsule C, the perforating part <NUM> includes a first punch <NUM>.

The beverage extracted from the beverage capsule C may be is discharged externally through the extracting part <NUM>.

In this case, even when high pressure is applied to the installing space MS, not to open the opening and closing part <NUM>, but to maintain a state in which the installing space MS is sealed, the link part <NUM> may be provided.

Hereinafter, with reference to <FIG>, each configuration will be described in detail.

The extracting part <NUM> includes a body <NUM>, a holder <NUM>, and a discharging member <NUM>.

A seat groove <NUM> allowing the holder <NUM> to be seated thereon may be provided in the body <NUM>, and the holder <NUM> may be inserted into the seat groove <NUM> to be seated thereon.

The installing space MS is formed in the holder <NUM>, and the beverage capsule C is installed in the installing space MS. To this end, an upper part of the installing space MS may be open and the installing space MS may have a shape corresponding to that of the beverage capsule C.

Since the beverage capsule C is inserted into the installing space MS from the open upper part of the installing space MS, the beverage capsule may be installed in the installing space MS.

Discharge holes <NUM> and <NUM> penetrate through a bottom surface of the seat groove <NUM> and a bottom surface of the holder <NUM> to be formed in positions corresponding thereto, respectively, and thus, a beverage extracted from the beverage capsule C is discharged therethrough.

The discharging member <NUM> is installed below the body <NUM>, and a discharge port <NUM> from which the beverage is discharged is provided therein.

The beverage is provided for the discharging member <NUM> through the discharge holes <NUM> and <NUM> formed in the bottom surface of the seat groove <NUM> and the bottom surface of the holder <NUM>, respectively, and the beverage is discharged externally through the discharge port <NUM>.

In addition, an insertion hole <NUM> is penetrated through and formed in the discharging member <NUM>, and the first punch <NUM> is disposed in the insertion hole <NUM>.

Here, a diameter of the insertion hole <NUM> is formed to be narrower downwardly, and the first punch <NUM> is provided with a stopper <NUM> having a shape corresponding to a shape of the insertion hole <NUM>. Thus, the insertion hole <NUM> is configured to be sealed by the first punch <NUM>.

The first punch <NUM> is disposed to be reciprocating moved, and the first punch <NUM> moves inside of the installing space MS through the discharge holes <NUM> and <NUM> to perforate the beverage capsule C. In addition, after the first punch <NUM> perforates the beverage capsule C, the first punch moves outside of the installing space MS, and thus, the stopper <NUM> allows the insertion hole <NUM> to be sealed thereby.

Thus, the beverage provided for the discharging member <NUM> not discharged externally through the insertion hole <NUM>, and is discharged externally through the discharge port <NUM>.

A reciprocating motion of the first punch <NUM> will be described later with respect to <FIG>.

The opening and closing part <NUM> is connected to the extracting part <NUM> to open or seal the installing space MS.

To this end, the opening and closing part <NUM> may include a cover <NUM> and a lever member <NUM>.

The cover <NUM> may be coupled to the lever member <NUM> to be rotated depending on a location of the lever member <NUM> so as to open and close the open upper part of the installing space MS.

Thus, as illustrated in <FIG>, the installing space MS may be sealed, or as illustrated in <FIG> and <FIG>, the installing space MS may be open.

To allow the cover <NUM> to be coupled to the lever member <NUM> and to be rotated, the cover <NUM> may be connected to the lever member <NUM>.

In addition, each of the cover <NUM> and the lever member <NUM> may be connected to the body <NUM>, as illustrated in <FIG>.

For example, each of the cover <NUM> and the lever member <NUM> may be connected to the body <NUM> by a connecting pin P to be rotated. Thus, the cover <NUM> and the lever member <NUM>, as illustrated in <FIG>, may be rotated based on the connecting pin P.

When a user applies force upwardly to the lever member <NUM>, to open an upper part of the installing space MS, the cover <NUM> may be rotated with the lever member <NUM>.

In addition, in the state described above, when a user applies a force downwardly the lever member <NUM>, to allow the upper part of the installing space MS to be closed by the cover <NUM>, the cover <NUM> may be rotated with the lever member <NUM>. Thus, while the beverage capsule C is installed in the installing space MS, the installing space MS may be sealed.

Meanwhile, when the installing space MS is sealed, to perforate an upper part of the beverage capsule C installed in the installing space MS, a second punch <NUM> may be provided in the cover <NUM>.

As a tip of the second punch <NUM> is formed to be sharpened, the beverage capsule C may be perforated thereby. As hot water supply flow paths 310a and 311a communicating each other are provided in the cover <NUM> and the second punch <NUM>, high-pressure hot water may be provided for the beverage capsule C through the hot water supply flow paths 310a and 311a.

While the installing space MS is sealed, even when high pressure is applied to the installing space MS, the link part <NUM> may serve to allow the opening and closing part <NUM> not to be open.

To this end, the link part <NUM> may include a first link member <NUM>, a second link member <NUM>, and a third link member <NUM>.

One side of the first link member <NUM> may be connected to the lever member <NUM> to be rotated, one side of the second link member <NUM> may be connected to the body <NUM> to be rotated, and one side of the third link member <NUM> may be connected to the cover <NUM> to be rotated.

In addition, the other side of the second link member <NUM> may be connected to the other side of the first link member <NUM> and the other side of the third link member <NUM> to be rotated.

Thus, the first link member <NUM>, the second link member <NUM>, and the third link member <NUM> may be coupled to the opening and closing part <NUM> to be rotated.

For example, due to an operation of the lever member <NUM>, the other side of the first link member <NUM> is rotated based on one side of the first link member <NUM>, and thus, the other side of the second link member <NUM> is rotated based on one side of the second link member <NUM>. Thus, the other side of the third link member <NUM> may be rotated based on one side of the third link member <NUM>.

Meanwhile, as illustrated in <FIG>, when the opening and closing part <NUM> allows the installing space MS to be sealed, a second center virtual line L2 extended from one side of the second link member <NUM> to the other side thereof may be located between a first center virtual line L1 extended from one side of the first link member <NUM> to the other side thereof and a third center virtual line L3 extended from one side of the third link member <NUM> to the other side thereof.

Thus, a direction of rotation of the second link member <NUM> due to movement of the first link member <NUM> when the lever member <NUM> is lifted up, may be different from a direction of rotation of the second link member <NUM> due to movement of the third link member <NUM> when the cover <NUM> is pushed up by applying high pressure to the installing space MS.

In addition, the third center virtual line L3 may be positioned closer to the discharge port <NUM> of the extracting part <NUM> than the first center virtual line L1.

Thus, as illustrated in <FIG> and <FIG>, while the installing space MS is sealed by the cover <NUM>, when the lever member <NUM> is lifted up, a direction of rotation of the second link member <NUM> due to movement of the first link member <NUM> may be a counterclockwise direction based on <FIG> and <FIG>. Thus, when the lever member <NUM> is lifted up, the cover <NUM> may be open.

Alternatively, when the lever member <NUM> is lowered to seal the installing space MS, a direction of rotation of the second link member <NUM> may be a clockwise direction based on <FIG> and <FIG>. Thus, when the lever member <NUM> is lowered, the cover <NUM> may be closed.

In addition, as illustrated in <FIG>, while the installing space MS is sealed by the cover <NUM>, when high pressure is applied to the installing space MS, a force is applied to a direction in which the cover <NUM> is lifted up. In this case, a direction of rotation of the second link member <NUM> due to movement of the third link member <NUM> may be a clockwise direction based on <FIG>.

Thus, the cover <NUM> may further close the upper part of installing space MS due to the third link member <NUM>.

In addition, a sawtooth-shaped groove <NUM> may be formed in the third link member <NUM>, and a sawtooth-shaped groove <NUM> may be formed in the body <NUM>. Thus, when the installing space MS is sealed by the cover <NUM>, the third link member <NUM> may be engaged with the body <NUM>.

When a force is applied in a direction in which the cover <NUM> is lifted by high pressure applied to the installing space MS, while the second link member <NUM> rotates in a clockwise direction, the third link member <NUM> is pulled thereby. Thus, the third link member <NUM> is more closely attached to the body <NUM>. As a result, even when high pressure is applied to the installing space MS, the cover <NUM> may not be open.

Meanwhile, the first link member <NUM>, the second link member <NUM>, and the third link member <NUM> may be provided as pairs to be symmetrical to each other on both sides of the extracting part <NUM> and the opening and closing part <NUM>.

In the other side of the second link member <NUM>, a rotating shaft RS for connecting two second link members <NUM> to each other may be provided therein.

Hereinafter, with reference to <FIG>, due to rotation of the opening and closing part <NUM>, an operation in which the perforating part <NUM> moves reciprocally will be described.

<FIG> is a cross-sectional view illustrating a state in which the opening and closing part is open in a beverage extracting device according to an exemplary embodiment of the invention, <FIG> is a cross-sectional view illustrating a state in which the opening and closing part is closing in a beverage extracting device according to an exemplary embodiment of the invention and <FIG> is a cross-sectional view illustrating a state in which the opening and closing part is closed in a beverage extracting device according to an exemplary embodiment of the invention.

With reference to <FIG>, the perforating part <NUM> is moved reciprocally due to rotation of the opening and closing part <NUM>.

To this end, the perforating part <NUM> may include the first punch <NUM> and a guide link <NUM>.

First, with reference to <FIG>, one side of the first punch <NUM> may be inserted inside of the discharging member <NUM> through the insertion hole <NUM> of the discharging member <NUM>.

As described previously, a diameter of the insertion hole <NUM> is formed to be narrower downwards, and the stopper <NUM> having a shape corresponding to a shape of the insertion hole <NUM> is provided in one side of the first punch <NUM>. Thus, the first punch <NUM> is prevented from falling out from the insertion hole <NUM>.

One side of the guide link <NUM> may be connected to the extracting part <NUM> to be rotated, and the other side of the guide link <NUM> may be connected to the other side of the first punch <NUM> to be rotated.

By self weight of the guide link <NUM>, the other side of the guide link <NUM> may be rotated based on one side of the guide link <NUM>. However, since the other side of the guide link <NUM> is connected to the first punch <NUM>, even when the other side of the guide link <NUM> is rotated by self weight, the first punch <NUM> may be stopped while being in close contact with the insertion hole <NUM>, due to the stopper <NUM> of the first punch <NUM>.

Thus, the guide link <NUM> may not be further rotated and may be supported in a stopped state.

Meanwhile, a bottom of the guide link <NUM> may be formed to have a curved surface having a predetermined radius of curvature.

When the second link member <NUM> is rotated in a clockwise direction or in a counter-clockwise direction due to an operation of the opening and closing part <NUM>, the rotating shaft RS connected to the second link member <NUM> may be sliding-moved with respect to the bottom of the guide link <NUM>.

In addition, a first stopper protrusion <NUM> may be formed in a portion of the bottom the guide link <NUM>, corresponding to one side of the guide link <NUM>, and a second stopper protrusion <NUM> may be formed in a portion of the bottom of the guide link <NUM>, corresponding to the other side of the guide link <NUM>.

With reference to <FIG>, when the opening and closing part <NUM> is closed, the second link member <NUM> rotates in a clockwise direction, and thus, the rotating shaft RS connected to the second link member <NUM> may rotate in a clockwise direction.

In this case, the rotating shaft RS is caught by the first stopper protrusion <NUM>. Due to a force in which the rotating shaft RS pushes the first stopper protrusion <NUM>, the other side of the guide link <NUM> may be rotated based on one side of the guide link <NUM>.

Since the other side of the guide link <NUM> rotates, the first punch <NUM> connected to the other side of the guide link <NUM> is lifted upwards. In this case, the first punch <NUM> is inserted inside of the installing space MS.

Thus, the beverage capsule C installed inside of the installing space MS may be perforated.

Next, as illustrated in <FIG>, when the opening and closing part <NUM> is closed to seal the installing space MS, the rotating shaft RS moves slidingly along a bottom of the guide link <NUM>, and thus, the rotating shaft is seated on the second stopper protrusion <NUM>.

In this case, the guide link <NUM> rotates in a counter-clockwise direction, and thus, the first punch <NUM> connected to the other side of the guide link <NUM> may be moved downwards due to rotation of the guide link <NUM> in a counterclockwise direction.

To this end, an elastic member <NUM> is provided in the perforating part <NUM>.

One side of the elastic member <NUM> may be fixed to the extracting part <NUM>, and the other side of the elastic member <NUM> may be fixed to the guide link <NUM>.

Thus, as illustrated in <FIG>, while the rotating shaft RS moves slidingly along the bottom of the guide link <NUM>, the other side of the guide link <NUM> is rotated in a counter-clockwise direction due to an elastic force of the elastic member <NUM>, and thus, the first punch <NUM> is in close contact with the insertion hole <NUM> while moving downwardly.

In other words, due to an operation of the opening and closing part <NUM>, the guide link <NUM> may rotationally reciprocating move, and the first punch <NUM> may linearly reciprocating move.

In the beverage extracting device <NUM> according to an exemplary embodiment in the present disclosure, after the first punch <NUM> perforates the beverage capsule C, the first punch moves downwards. Thus, enough space for discharging a beverage extracted from the beverage capsule C through a perforated portion of the beverage capsule may be secured.

In the case in which the space for discharging a beverage extracted from the beverage capsule C is not secured, beverage powders are highly compressed inside of the beverage capsule C, thereby significantly lowering an extraction function of the beverage.

However, in the beverage extracting device <NUM> according to an exemplary embodiment in the present disclosure, since enough space for discharging a beverage extracted from the beverage capsule C through the perforated portion of the beverage capsule is secured, an extraction function of the beverage may be improved.

<FIG> is a cross-sectional view illustrating a state in which the opening and closing part is open in a beverage extracting device according to another exemplary embodiment of the invention, <FIG> is a cross-sectional view illustrating a state in which the opening and closing part is closing in a beverage extracting device according to another exemplary embodiment of the invention, and <FIG> is a cross-sectional view illustrating a state in which the opening and closing part is closed in a beverage extracting device according to another exemplary embodiment of the invention.

A beverage extracting device <NUM>' according to another exemplary embodiment of the invention is the same as the beverage extracting device <NUM> according to an exemplary embodiment of the invention except a guide link <NUM>', descriptions will be omitted, other than with regard to the guide link <NUM>'.

In another exemplary embodiment in the present disclosure, a rotating link member <NUM> may be further included in the guide link <NUM>'.

To this end, an insertion groove <NUM>' may be formed in a portion of a bottom of the guide link <NUM>' corresponding to one side of the guide link <NUM>', and the rotating link member <NUM> is inserted into the insertion groove <NUM>'. Thus, one side of the rotating link member may be connected to the guide link <NUM>' to be rotated.

The insertion groove <NUM>' may have a shape corresponding to a shape of the rotating link member <NUM>.

In this case, the other side of the rotating link member <NUM> is rotated based on one side of the rotating link member <NUM> by self weight, and thus, a portion of the other side of the rotating link member <NUM> may protrude outwardly of the guide link <NUM>'.

Thus, when the opening and closing part <NUM> is closed, the rotating shaft RS pushes the other side of the rotating link member <NUM> protruding outwardly of the guide link <NUM>', and thus, the guide link <NUM> is rotated. Thus, due to rotation of the guide link <NUM>, the first punch <NUM> is inserted inside of the installing space MS.

Until the installing space MS is sealed by closing the opening and closing part <NUM>, the rotating shaft RS moves along a bottom of the guide link <NUM>' to be seated on a stopper protrusion <NUM>' of the guide link <NUM>'.

When the opening and closing part <NUM>, which is closed, is open, the rotating shaft RS moves along the bottom of the guide link <NUM>' in a direction opposite to a direction in which the rotating shaft RS moves when the opening and closing part <NUM> is closed.

In this case, the rotating shaft RS pushes the rotating link member <NUM> protruding outwardly of the guide link <NUM>', and thus, the other side of the rotating link member <NUM> is rotated based on one side of the rotating link member <NUM> to be inserted inside of the insertion groove <NUM>'.

Due to a structure described above, when the opening and closing part <NUM> is open, the rotating link member <NUM> allows movement of the rotating shaft RS not to be limited. Thus, the opening and closing part <NUM> may open with a small force.

Through the exemplary embodiments described above, a beverage extracting device according to an exemplary embodiment in the present disclosure and a water purifier including the same may allow a beverage extracted from a beverage capsule to be easily discharged from the beverage capsule.
