X, and the title of the invention is “Horizontal Rotary Beverage Preparation Machine”, and filed with the Chinese Patent Office on December 4, 2014, the application number is 20141417415.4, the name of the invention is “Horizontal The priority is claimed based on the Chinese patent application "Beverage preparation method of the rotary beverage preparation machine", the entire contents of which are incorporated herein by reference.

  The present application relates to a beverage machine and a beverage preparation method thereof, and more particularly, to a horizontal rotary beverage preparation machine and a beverage preparation method thereof.

  As the standard of living rises and the habits of eating habits are improved, more people drink tea, soy milk and coffee. With this, beverage preparation machines have become increasingly popular with consumers.

  Conventionally, commercially available beverage preparation machines are divided into vertical beverage preparation machines and horizontal beverage preparation machines. A vertical beverage preparation machine refers to a capsule whose central axis is provided along the vertical direction, while a horizontal beverage preparation machine refers to a capsule whose central axis is provided along the horizontal direction. Point to. A horizontal beverage preparation machine usually includes a base having a preparation cavity, a preparation head, a liquid injection needle and a withdrawal needle provided in the preparation head along the horizontal direction, and a liquid supply means for supplying a liquid to the preparation head. A preparation cup and a capsule provided in the preparation cup along the transverse direction. As the operation method, the liquid is automatically injected into the capsule by the preparation head, the liquid and the capsule are mixed and dissolved, and then the beverage is discharged by the withdrawal needle. Thereby, preparation of a drink is performed and it uses for a user's use.

  By the way, since the capsule is set along the horizontal direction, the beverage powder in the capsule is gathered in the lower part. In this case, when a liquid flow is jetted and injected into the capsule as it is with a liquid injection needle, a part of the beverage powder gathered at the lower part is not flushed with the liquid flow, so that a phenomenon of becoming granular or massive may occur. As described above, since a large amount of beverage powder is left in the capsule after the preparation is completed, the beverage is wasted, while affecting the nutritional value and texture of the beverage. Furthermore, since the connection between the liquid injection needle and the liquid supply means is inconvenient and difficult to assemble, the production efficiency is lowered. In addition, water leakage is likely to occur, which affects the service life of the device.

  An object of the present invention is to provide a horizontal rotating beverage preparation machine having an excellent preparation effect and a simple structure, and a beverage preparation method using the same.

In the preparation machine, the liquid injection needle injects liquid along the central axis of the capsule, and the jet direction of the liquid injection needle is provided so as to cross the axis of the liquid injection needle and toward the side wall of the capsule. And the withdrawal needle is The beverage preparation machine is further provided with a drive device attached to a base, and the drive device provides a horizontal rotary beverage preparation machine that rotationally drives the liquid injection needle. Yes.

  Further, a water supply head formed integrally with the liquid injection needle is provided on one end side of the liquid injection needle communicated with the liquid supply means.

  Furthermore, when the angle formed by the jet direction of the liquid injection needle and the axis of the liquid injection needle is α, the relationship of 50 ° ≦ α ≦ 85 ° is satisfied.

  Further, the water supply head is connected to the liquid supply means via a joint, and the water supply head is inserted into the joint and is provided to be rotatable in the joint.

  Furthermore, a first seal ring that is fitted around the water supply head is disposed between the water supply head and the joint.

  Further, the preparation head is further provided with a punch plate attached to the base and provided with a through hole through which the injection needle passes, and the punch plate is interposed between the injection needle and the punch plate. A second seal ring provided in the through hole is disposed.

  Further, the withdrawal needle is provided below the liquid injection needle, the withdrawal needle pierces the membrane to form a puncture hole, and the distance between the puncture hole and the side wall of the capsule is L1 , L1 ≧ 2 mm is satisfied.

  Furthermore, one end side of the withdrawal needle extending into the capsule is cut obliquely to form a needle tip, and the obliquely cut portion of the needle tip is formed as an inclined cut surface, and the inclined cut surface is directed upward. The pull-out hole of the pull-out needle is provided in the inclined cut surface.

  Furthermore, the rotation speed of the liquid injection needle is 30 rpm to 250 rpm.

  The beverage preparation method of the horizontal rotary beverage preparation machine includes the following steps. That is, the capsule is pierced by the liquid injection needle, the water supply step for supplying the liquid into the capsule, and the drive device rotates the liquid injection needle to form the jet region by the liquid injection needle, and the beverage powder is in the jet region. A preparation step for flushing with liquid flow to mix and dissolve, and a beverage discharge step for discharging the beverage prepared from the beverage powder from the capsule by piercing the capsule with a withdrawal needle.

  In the present invention, the “jet region” refers to a trajectory formed by moving a liquid flow by rotating a liquid injection needle and moving the liquid flow. The phrase “the central axis of the capsule is provided along the lateral direction” means that the central axis of the capsule is in a horizontal or substantially horizontal state. The “powder lump” refers to a lump that is wet on the outside and is surrounded by dry powder.

  The present invention has the following advantageous effects.

  First, the liquid injection needle injects liquid along the center axis of the capsule, the jet direction of the liquid injection needle is provided so as to cross the axis of the liquid injection needle and toward the side wall of the capsule, and the beverage machine The drive device rotates the liquid injection needle. Accordingly, a swirling jet of liquid is generated around the central axis of the liquid injection needle, that is, the central axis of the capsule, so that the liquid and the beverage powder are mixed and dissolved, and the mixing and dissolution of the liquid and the beverage powder are promoted. Since the powder is sufficiently dissolved and there is no residue, the texture and nutritional value of the beverage are improved. In particular, since the needle is rotating, it is easy to form a conical jet region around the center of the capsule. Therefore, the beverage powder is quickly and sufficiently mixed and dissolved by the water flow jetted from the needle. Further, since the liquid withdrawal needle is provided below the liquid injection needle, the beverage withdrawal path is shortened, and furthermore, the beverage can be quickly and conveniently discharged by the gravity action.

  Second, since the water supply head integrally formed with the liquid injection needle is provided on one end side of the liquid injection needle communicated with the liquid supply means, the structure is simplified. This facilitates the connection between the injection needle and the liquid supply means, facilitates assembly during manufacturing, improves the manufacturing efficiency, increases the reliability when the injection needle rotates, and prevents water leakage. Therefore, the service life of the device can be extended.

  Third, when the angle formed by the jet direction of the liquid injection needle and the axis of the liquid injection needle is α, the relationship of 50 ° ≦ α ≦ 85 ° is satisfied. This ensures that the reflection point of the liquid jetted from the liquid injection needle is on the side wall of the capsule, so that the liquid jetted from the liquid injection needle can produce a larger swirling jet, which can be used as a beverage. Dissolution of the powder becomes quicker and sufficient, and the texture and nutritional value of the beverage are improved. If α is less than 50 °, since the reflection point of the liquid from the injection needle is out of the side wall of the capsule or at a low position on the side wall of the capsule, the swirling jet generated by the jetted liquid becomes small, and the preparation of the beverage The effect is degraded. On the other hand, when α exceeds 85 °, since the reflection point of the liquid from the injection needle is at a high position on the side wall of the capsule, the jetted liquid is reflected by the side wall toward the capsule film, while the beverage powder becomes the capsule. The beverage powder is not sufficiently dissolved, is wasted, and the beverage texture is not good.

  Fourth, the water supply head is connected to the liquid supply means via a joint and is rotatably provided in the joint. As a result, the connection between the injection needle and the liquid supply means becomes convenient, so the reliability during rotation of the injection needle is improved, the leakage of the liquid is prevented, and the service life of the device can be extended. It becomes possible.

  Fifth, a first seal ring that is externally fitted to the water supply head is disposed between the water supply head and the joint. Thereby, the sealing performance between a water supply head and a joint is strengthened, and the water leak at the time of rotation of a liquid injection needle | hook is prevented.

  Sixth, a second seal ring provided in the through hole of the punch plate is disposed between the injection needle and the punch plate. Thereby, at the time of preparation of a drink, a drink is prevented from entering between an injection needle and a punch plate, the propagation of bacteria is controlled, and hygiene is improved.

  Seventh, the withdrawal needle pierces the membrane to form a puncture hole, and when the distance between the puncture hole and the side wall of the capsule is L1, the relationship of L1 ≧ 2 mm is satisfied. Thereby, when a swirling jet is generated by the jetted liquid, since the beverage powder can pass between the drawer needle and the side wall of the capsule, it is not clogged between the drawer needle and the side wall of the capsule. Since it is filled with beverage powder, the risk of explosion due to excessive pressure of the capsule can be avoided, and safety in use is improved. If L1 is less than 2 mm, the beverage powder tends to be clogged between the withdrawal needle and the side wall of the capsule. Therefore, the clogging of the withdrawal needle may increase the pressure of the capsule and cause explosion.

  Eighth, one end side of the withdrawal needle extending into the capsule is obliquely cut to form a needle tip, and the obliquely cut portion of the needle tip is an inclined cutting surface, and the inclined cutting surface is upward The lead-out hole of the lead-out needle is provided in the inclined cut surface. As a result, when a swirling jet is generated by the jetted liquid, the beverage powder does not clog the extraction needle when passing between the extraction needle and the side wall of the capsule. Can be avoided, and the beverage powder that has not been dissolved is prevented from being discharged as it is, thereby improving the texture of the beverage.

  Ninth, the rotation speed of the injection needle is 30 rpm to 250 rpm. As a result, the beverage powder is sufficiently dissolved to improve the texture of the beverage, and it is possible to ensure the preparation efficiency. Furthermore, since the withdrawal needle is not easily clogged, the risk of the capsules exploding due to excessive pressure is also avoided. Here, if the rotational speed is less than 30 rpm, the rotation of the drawer needle is too slow, so that the dissolution rate of the beverage powder is slowed and the beverage preparation efficiency is lowered. Furthermore, the withdrawal needle is easily clogged with beverage powder, which is dangerous because the capsule may explode. On the other hand, when the rotation speed exceeds 250 rpm, a part of the undissolved beverage powder is released from the withdrawal needle along with the liquid flow, which affects the texture of the beverage.

  Tenth, in the present method, since the injection direction of the injection needle intersects the axis of the injection needle, the liquid flow is injected by the injection needle toward the beverage powder. In addition, a procedure for rotationally driving the injection needle by the drive device is provided in the preparation step. As a result, a jet region is formed by the injection needle, and the beverage powder is flushed into the liquid flow in the jet region to be mixed and dissolved, so that the mixing and dissolution of the liquid and the beverage powder is promoted and the beverage powder is sufficiently dissolved. Since there is no residue, the texture and nutritional value of the beverage are improved. Moreover, since a swirling jet is generated during the rotation of the liquid injection needle, the dissolution of the beverage powder is more effectively promoted, and the beverage preparation efficiency and texture are improved.

The liquid supply means 6 is provided on one side of the base 1, and the preparation cup 8 is provided on the other side of the preparation cavity 2. The central axes of the liquid injection needle 4, the extraction needle 5 and the capsule 7 are all arranged along the lateral direction, that is, the axial lines of the liquid injection needle 4 and the extraction needle 5 and the central axis of the preparation head 3 overlap or become parallel. The center axis of the capsule 7 is in a horizontal or substantially horizontal state. The jet direction of the liquid injection needle 4 is provided so as to cross the axis of the liquid injection needle 4 and toward the side wall of the capsule 7. As a result, a swirling jet of liquid is generated around the central axis of the liquid injection needle, so that the liquid and beverage powder are mixed and dissolved with each other, the mixing and dissolution of the liquid and beverage powder are promoted, and the beverage powder is sufficiently dissolved. Since there is no residue, the texture and nutritional value of the beverage are improved.

  In this embodiment, the water supply head 42 formed integrally with the liquid injection needle 4 is provided on one end side of the liquid injection needle 4 that communicates with the liquid supply means 6, so that the structure is simple. Since the connection between the liquid supply means and the liquid supply means becomes convenient, the assembly at the time of manufacture becomes easy, the manufacturing efficiency is improved, the reliability at the time of rotation of the injection needle is increased, and no water leaks occur. The service life of the device can be extended.

  The water supply head 42 is connected to the liquid supply means via the joint 10, and the water supply head 42 is inserted into the joint 10 and is provided so as to be rotatable in the joint 10. As a result, the connection between the liquid injection needle and the liquid supply means becomes convenient, so that reliability during rotation of the liquid injection needle is improved, liquid leakage is prevented, and the service life of the device is extended.

  The beverage preparation machine further comprises a drive device 9. The drive device 9 is a motor that rotates the liquid injection needle 4 to prepare a beverage. A first seal ring 12 is provided between the water supply head 42 and the joint 10, and the first seal ring 12 has a ring shape, and the material thereof may be silicone. The water supply head 42 is provided with an annular groove, and the first seal ring 12 is externally fitted into the annular groove. By comprising in this way, since a 1st seal ring is provided between a water supply head and a coupling and the said 1st seal ring fits in a water supply head, it is between a water supply head and a joint. Sealing performance is improved, and water leakage during rotation of the injection needle is prevented.

  A second seal ring 13 is provided between the injection needle 4 and the punch plate 32. The second seal ring 13 has a ring shape, and the material thereof may be silicone, and the punch plate 32 through holes 321 are provided. A second seal ring is provided between the liquid injection needle and the punch plate, and the second seal ring is disposed in the through hole of the punch plate so that the beverage can be injected into the liquid injection needle and the punch when preparing the beverage. Invasion between the plates is prevented, bacterial growth is suppressed, and hygiene is improved.

  The punch plate 32 is further provided with a third seal ring 14 for sealing the preparation cup 8, the third seal ring 14 is a semi-closed annular structure, and its longitudinal section is “U "It has a letter shape. An annular groove is provided at the lower end of the punch plate 32, the third seal ring 14 is mounted in the annular groove, and the “U” -shaped opening of the third seal ring 14 is fixed to the annular groove. The “U” -shaped bottom of the seal ring 14 is configured to contact the preparation cup 8 and seal the preparation cup. With this configuration, the third seal ring has a semi-closed annular structure, and the longitudinal section thereof has a “U” shape. Therefore, the third seal ring has a large amount of deformation. And a small deformation coefficient is obtained. Now, when there is no raw material cup, it is possible to securely seal between the preparation head and the preparation cup, and water leakage does not occur, but when the capsule is put in the preparation cup and the compression amount becomes large In addition, the increase in tightening force can be relaxed. In addition, by fixing the “U” -shaped opening of the third seal ring in the annular groove, the “U” -shaped bottom of the third seal ring is brought into contact with the preparation cup to seal the preparation cup The third seal ring can be greatly deformed to reduce the tightening force generated when the capsule is inserted, and the slurry can be removed from the “U” -shaped opening. It is possible to maintain hygiene because no intrusion occurs.

  The material of the withdrawal needle 5 may be plastic. One end side of the withdrawal needle 5 that extends into the capsule 7 is cut obliquely to form a needle tip, the obliquely cut portion of the needle tip is an inclined cut surface, and the inclined cut surface is provided to face upward. It has been. With this configuration, when the jetted liquid becomes a swirling jet, the beverage powder does not clog the extraction needle when passing between the extraction needle and the side wall of the capsule. It is possible to avoid the risk of explosion due to being too much, and it is possible to avoid that the undissolved beverage powder is discharged as it is, so that the texture of the beverage is improved.

  The withdrawal needle 5 is provided directly below the injection needle 4, the extraction needle 5 and the injection needle 4 are provided at an interval, and the extraction needle 5 forms a puncture hole by piercing the membrane, and the puncture hole and the capsule 7 When the distance from the side wall is L1, the relationship of L1 ≧ 2 mm is satisfied. By comprising in this way, since the extraction needle | hook is provided directly under the liquid injection needle | hook, a drink can be discharged | emitted easily. Furthermore, when the distance between the puncture hole and the side wall of the capsule is L1, the relationship of L1 ≧ 2 mm is satisfied, so that when the jetted liquid becomes a swirling jet, the beverage powder is separated from the withdrawal needle and the side wall of the capsule. Because it can pass between, the clogging between the withdrawal needle and the side wall of the capsule is not clogged, so the withdrawal needle is clogged with beverage powder, avoiding the risk of the capsule pressure becoming too high and exploding The safety is improved. If L1 is less than 2 mm, the beverage powder is likely to be clogged between the withdrawal needle and the side wall of the capsule, so that the withdrawal needle is clogged and the pressure of the capsule becomes too high, which may cause an explosion. Therefore, in this embodiment, L1 = 4.5 mm. Of course, L1 is 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, etc. Since L1 may be 2 mm or more, it is not enumerated here. It should be understood that the above list is only preferred embodiments and is not meant to be limited to this range.

  As shown in FIGS. 3 and 4, the material of the injection needle 4 may be plastic. A needle tip is provided on one end side that extends into the capsule of the liquid injection needle 4, and the needle tip is formed by obliquely cutting the end of the liquid injection needle 4. The liquid injection hole 4 is provided on the side wall on one end extending into the capsule 7 of the liquid injection needle 4, the liquid injection hole has a circular shape, and when the hole diameter of the liquid injection hole of the liquid injection needle 4 is D, 0 The relationship of 8 mm ≦ D ≦ 2 mm is satisfied. By comprising in this way, since the jetted liquid can produce the optimal swirling jet, a drink powder is melt | dissolved rapidly and effectively, and the preparation effect of a drink is improved. If D is less than 0.8 mm, the flow rate is small, which is disadvantageous for the preparation effect. On the other hand, the internal pressure of the device becomes too large, which is disadvantageous for the sealing performance, and affects the service life of the device. When D2 exceeds 2 mm, the dimension of the liquid injection hole is too large, the linear velocity of the jetted liquid is reduced, the impact force is reduced, and the preparation effect is deteriorated. Therefore, in this embodiment, D is set to 1.2 mm. Of course, D is set to 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm and 2 mm. be able to.

  When the distance from the reflection point where the liquid injected from the injection needle 4 hits the side wall of the capsule 7 is L2 and the height of the capsule 7 is H, the relationship of L2 <H is satisfied. And L2 shall be 0.2H-0.8H. By configuring in this way, a larger swirling jet is generated by the liquid jetted from the injection needle, so that the beverage powder can be dissolved more quickly and sufficiently, and the texture and nutritional value of the beverage are improved. Moreover, since L2 is set to 0.2H to 0.8H, the liquid jetted from the injection needle is reflected from the side wall of the capsule to generate an optimal swirling jet, so that the beverage powder can be made more effective and quick. Can be dissolved. If L2 is less than 0.2H, the reflection point of the liquid injected from the injection needle is out of the side wall of the capsule or at a low position on the side wall of the capsule, so that the swirling jet generated by the jetted liquid is small, and the beverage The preparation effect of is deteriorated. On the other hand, when L2 exceeds 0.8H, since the reflection point of the liquid injected from the injection needle is at a high position on the side wall of the capsule, the jetted liquid is reflected from the side wall and then travels toward the capsule film. Since the beverage powder is collected on the bottom wall of the capsule, the beverage powder is not sufficiently dissolved, is wasted and the texture of the beverage is not good.

  When the length of the liquid injection needle 4 extending into the capsule 7 is L3, the relationship of L3 <L2 is satisfied. With this configuration, since the liquid jetted from the injection needle hits the side wall of the capsule and is reflected toward the bottom wall of the capsule, some beverage powder is scattered to the capsule membrane and flushed with liquid. This avoids wasteful use of beverage powder and a decrease in beverage concentration and texture.

  When the angle formed by the jet direction from the injection needle 4 and the axis of the injection needle 4 is α, the relationship of 50 ° ≦ α ≦ 85 ° is satisfied. By configuring in this way, it is ensured that the reflection point of the liquid jetted from the injection needle is on the side wall of the capsule, and a larger swirling jet can be generated by the liquid jetted from the injection needle. Thus, the beverage powder can be dissolved more rapidly and sufficiently, and the texture and nutritional value of the beverage are further improved. If α is less than 50 °, since the reflection point of the liquid from the injection needle is out of the side wall of the capsule or at a low position on the side wall of the capsule, the swirling jet generated by the jetted liquid becomes small, and the preparation of the beverage The effect is degraded. On the other hand, when α exceeds 85 °, since the reflection point of the liquid from the injection needle is at a high position on the side wall of the capsule, the jetted liquid is reflected from the side wall and then goes to the capsule film, while the beverage powder Are collected on the bottom wall of the capsule, the beverage powder is not sufficiently dissolved and is wasted, while the texture of the beverage is not good. Therefore, in this embodiment, α is set to 75 °. Of course, α is set to 50 °, 53 °, 55 °, 58 °, 60 °, 63 °, 65 °, 68 °, 70 °, 73 °, 78 °, 80 °, 83 °, 85 °. Also good.

  The number of rotations of the injection needle 4 is 30 rpm to 250 rpm. By comprising in this way, drink powder is fully melt | dissolved and the food texture of a drink becomes favorable and it becomes possible to ensure preparation efficiency. In addition, the withdrawal needle is less likely to be clogged, thus avoiding the risk of the capsule exploding due to excessive pressure. If the rotation speed is less than 30 rpm, the rotation of the drawing needle is too slow, so that the dissolution rate of the beverage powder is slowed and the beverage preparation efficiency is lowered. Furthermore, since the withdrawal needle is easily clogged with beverage powder, the capsule is dangerous because it can explode. On the other hand, when the rotation speed exceeds 250 rpm, a part of the undissolved beverage powder is released from the withdrawal needle along with the liquid flow, which affects the texture of the beverage. Therefore, in this embodiment, the number of rotations of the injection needle is 140 rpm. Of course, the rotation speed is set to 30 rpm, 40 rpm, 50 rpm, 60 rpm, 70 rpm, 80 rpm, 90 rpm, 100 rpm, 110 rpm, 120 rpm, 130 rpm, 150 rpm, 160 rpm, 170 rpm, 180 rpm, 190 rpm, 200 rpm, 210 rpm, 220 rpm, 230 rpm, 240 rpm, 250 rpm. You may do it.

  The material of the withdrawal needle 5 may be plastic. One end side of the withdrawal needle 5 that extends into the capsule 7 is cut obliquely to form a needle tip, the obliquely cut portion of the needle tip is an inclined cut surface, and the inclined cut surface is provided to face upward. The lead-out hole of the lead-out needle 5 is provided on the inclined cut surface. With this configuration, when the jetted liquid becomes a swirling jet, the beverage powder does not clog the extraction needle when passing between the extraction needle and the side wall of the capsule. It is possible to avoid the risk of explosion due to being too much, and it is possible to avoid that the undissolved beverage powder is discharged as it is, so that the texture of the beverage is improved. Further, since the material of the withdrawal needle is plastic, processing and manufacturing of the withdrawal needle is convenient, and the cost can be reduced.

  It should be understood that the material of the injection needle may be stainless steel.

  About the drink preparation method provided in a present Example, the specific operation | movement process is as follows.

  Step 1: When the customer puts the capsule 7 into the beverage machine and presses the start key, the beverage machine starts to operate.

  Step 2 (Water supply step): The capsule 7 is pierced by the injection needle 4 and the liquid is supplied into the capsule 7.

  Step 3 (Preparation step): The drive device 9 rotates and drives the liquid injection needle 4 to form a conical direct flow region 100 centered on the liquid injection needle 4 and a part of the beverage powder gets wet. A paste layer is formed on the surface, and further a powder lump is formed. The powder mass continues to be flushed with the liquid in the conical direct flow region 100, and at the same time, the conical direct flow region 100 is reflected from the side wall of the capsule 7 during rotation, and the "V" -shaped reflective flow region 110 is formed. As formed, the beverage powder is flushed in both the conical direct flow region 100 and the “V” shaped reflective flow region 110. Here, after a part of the beverage powder gets wet, a paste layer is formed on the surface, and further a powder lump is formed. Then, the powder lump is continuously flushed with the liquid in the conical direct flow region 100 and the “V” -shaped reflection flow region 110, whereby the powder lump is crushed or reduced. Then, the pulverized or reduced powder lump is further flushed with the liquid flow into the jet region and melted.
