3 to 5, since the pressing portion 111 is resiliently supported inside the main body 30 ', when the cartridge C is not caught in the fitting portion 30A, (111) is spaced apart from the inner wall of the main body (30 ') by a predetermined distance in the inward direction,

Thereafter, when the cartridge C is inserted into the fitting portion 30A, the pressing portion 111 is inserted into the cartridge C while being pushed outwardly of the main body 30 'in accordance with the diameter of the cartridge C,

When the insertion is completed, the pressing portion 111 can use the elastic force to fix the cartridge C in the correct position.

At this time, when the size of the cartridge C, that is, the diameter thereof is equal to the diameter of the fitting portion 30A of the main body 30 'or is slightly smaller than the diameter of the fitting portion 30A of the main body 30' The fixing of the cartridge C through the fixing means 110 is easy,

When the difference between the diameter of the cartridge C and the diameter of the fitting portion 30A of the main body 30 'is large as in the cartridge C shown in Fig. 6,

The pressing portion 111 must be positioned inside by a difference in diameter between the fitting portion 30A and the cartridge C and therefore the pressing portion 111 is provided with a pressing portion 111 for securing a distance in which the pressing portion 111 can move inward and outward, The size or shape of the cartridge C can not be stably fixed in the case of the cartridge C having a relatively small diameter.

The present invention introduces the receptacle 31 having the fitting portion 30A into which the different types of cartridges C can be respectively received so that the receptacle 31 is inserted into the fitting portion 30A of the main body 30 ' Respectively.

That is, when the receptacle 31 is used, the fitting portion 30A of the main body 30 'functions as a mounting portion of the receptacle 31, and the inner space of the receptacle 31, in which the cartridge C is fitted, (30A).

Therefore, according to the present invention, a large number of the receivers 31 are secured according to the type of the cartridges C, and the receivers 31 can be stored by utilizing the cartridge C storage section, (C) is selected so that the beverage can be extracted.

The present invention can be applied to various types of cartridges C depending on the combination of the receptacle 30 and the receptors 31 by introducing a plurality of receptacles 30 and a plurality of receptors 31 that can be accommodated in the receptacles 30, It is possible to perform the beverage extraction using only one beverage maker and ultimately to provide a multi-beverage maker.

3 to 5, the pressing portion 111 of the fixing means 110 is provided with a pair of pressing portions 111 for pressing and fixing the outer surface of the cartridge C or the receiving portion 31, And the pressing piece 112,

So that the cartridge C or the receptor 31 is mounted and fixed to the main body 30 'at a more stable and precise position.

3 to 5, the fixing means 110 constituted by the pair of pressing pieces 112 and the elastic piece 115 are arranged in parallel with each other with respect to the hinge connecting portion 115A of the elastic piece 115 Swinging in the opposite direction (i.e., like scissors)

Accordingly, the elastic body 116 provided between the elastic pieces 115 exerts an elastic force in a direction in which the elastic pieces 115 are moved away from each other,

The pressing piece 112 is in a state in which the pressing piece 112 is swung inwardly of the main body 30 'when the cartridge C or the receiver 31 is not mounted on the main body 30' (that is, (The state in which the distal end portions of the distal end portions 112 are moved close to each other)

When the cartridge C or the receptor 31 is mounted on the main body 30 ', the pressing piece 112 is opened and the cartridge C or the receptor 31 is pressed in the direction opposite to the direction of the elastic force of the elastic body 116 So that stable fixing can be performed.

That is, as shown in FIG. 3, when the diameter of the cartridge C is the same as or similar to the diameter of the fitting portion 30A of the main body 30 '(that is, when the separate receptacle 31 is not required The user inserts only the cartridge C into the fitting portion 30A of the main body 30 'so as to extract the beverage (at this time, the receivers 31 are stored in the storage portion)

4 and 5, when the cartridge C having a relatively small diameter is used as compared with the main body 30 ', it is possible to select the receptors 31 corresponding to the respective cartridges C, The receptacle 30 can be attached to the fitting portion 30A of the receptacle 31 and then the receptacle 30 can be attached to the receptacle 30 to extract the beverage.

 The present invention can be applied to a cartridge (C) or a receptor (31) through a fixing means (110) by utilizing a pin spring of a similar ' So that it can be easily fixed.

Further, the receptacle 30 of the present invention may further include a foam generating means for improving the crema,

First, as can be seen from the combined perspective view of Fig. 13A (other components are shown in Figs. 1 to 12) with respect to the first foam generating means 60A,

(30A, 31A) for accommodating the extraction object P, in particular, the cartridge (C) in which the coffee (P) is embedded, is arranged in the receptacle (30) provided with the receptacle (31) And is mounted in a manner communicating with the communication path.

The first foam generating means 60A introduces a separate panel member for ensuring the fixing force, and the panel member also has a passing portion communicating with the communication passage of the receptacle 30 receptacle 31. [

Particularly, the panel member F for fixing the first foam generating means to the receptor 31 of the receptacle 30 is provided with a perforated disc 55 (see FIG. 1) in accordance with one-source multi-use or one-source multi- ) Function,

And the passing portion of the panel member functions as the passing portion 55b of the perforating disk 55. [ The first foam generating means is provided with three discharge portions 61b capable of communicating with the three passage portions 55b arranged at regular intervals around the perforation projection 55a.

The core of the first foam generating means 60A is a flexible shielding portion 61a that partially covers the passing portion 55b.

The core of the first foam generating means 60A is essentially composed of an extract liquid discharge portion 61b connected to the communication path of the receptor 31 of the receptacle 30, particularly the bottom surface portion 37, And a flexible shielding portion 61b provided around the discharge portion. In this case as well, the flexible shielding portion 61b is sufficiently vibrated, whereby the amount of foam or crema can be increased while impacting the extract liquid dropped and discharged.

In addition, when the panel member F or the perforated disk 55 is introduced, the flexible shielding portion 61b is exposed in the free end form due to the passage of the panel member F or the perforated disk 55, Is discharged through the liquid passing portion (55b), so that the liquid is contacted and collided with the flexible shield (61b) more intensively.

The extent to which the flexible shielding portion 61b covers the liquid extracting portion 55b can be adjusted in consideration of the foam or crema generation amount, the liquid ejection flow rate, and the like.

On the other hand, as can be seen from the single perspective view of the lower one-dot chain line in the lower one-dot chain line of Figs. 13A and 13A (other components are shown in Figs. 1 to 12)

Only the portion corresponding to the flexible shielding portion 61a can be made of flexible synthetic resin or a silicon sheet (or film).

Preferably, the flexible shielding or first foam generating means (and further to the second foam generating means) is a silicone material or other safety material with a low risk of exposure to environmental hormones even at high temperatures.

The 'flexible' shielding portion 61a vibrates finely due to the pressure or impact of the extracted liquid to be discharged or the vibration of the beverage maker itself due to a pump or the like, Or the amount of generated crema can be increased.

Size, and number of the flexible shielding portions 61a and the ejection liquid ejecting portions 61b are determined in accordance with the size and number of the passage portions of the panel member F or the perforating disk 55,

The thickness of the flexible shielding portion 61a (or the first foam generating means 60A) is selected in consideration of ensuring vibration characteristics, ensuring airtightness, ensuring durability, and the like.

Further, as can be seen from the exploded cross-sectional view of Fig. 13B (other components are shown in Figs. 1 to 12), the second foam generating means 60B is formed,

The receptacle 30, particularly the receptacle 31, is arranged below the first foam generating means and has a communication hole 63 through which the extract liquid passes,

This communication hole is connected to the passing portion of the upper panel member F or the perforating disk 55 and the discharge portion 61b of the first foam generating means 60A,

And is connected to the communication path of the bottom portion of the receptacle (30) receptacle (31) of the lower receptacle (30).

The detailed size (the size of each cross-sectional area when viewing the flat cross-section of each traffic section)

The second communication portion? Fourth communication portion> the fifth communication portion> the first communication portion> the third communication portion.

However, it is preferable that the size of the first communication portion ≒ the third communication portion ≒ the fifth communication portion, and the sizes of the communication portions 1 through 3 or the first through fifth communication portions are different from each other. Accordingly, the effect of increasing the amount of foam or crema due to the pressure difference in each communication part can be obtained.

If necessary, the diameter of the communicating hole may be varied in the communication hole so that the number of communication parts in which the narrow width and the wide width are repeated may be further increased. At this time, the communication part 63c formed in the thin plate- May have a plurality of structures spaced apart from each other.

Further, the panel member F or the perforating disk 55 and the first foam generating means 60A and the second foam generating means 60B have overlapping portions or rims 55c, 61c and 65a, respectively, , The hermeticity and fixing force for preventing the leakage of the extractive fluid are obtained at this portion,

The extracting target body P is directly accommodated in the sieve 20 in a manner different from that of the main body 30 'constituting the receptacle 30, so that the beverage is extracted.

The sieve 20 is closely attached to the first mounting portion of the receptacle 30 main body 30 'and the foam increasing member 40 is interposed between the sieve 20 and the first mounting portion of the main body 30'.

The foam increasing body is preferably made of an elastomer such as synthetic rubber or a silicone material and has flexibility and softness. Especially, it is preferable to use a material which prevents the harmful substance (especially, the environmental hormone) .

10 (B), on the upper surface of the foam increasing body 40, a guide projection 43 and a guide projection 43 (see FIG. 10) formed radially so that the coffee extracted by the hot water is guided to the hollow foam- And a retention protrusion 45 connected to the retention protrusion 45 is formed so that the foam or crema (covering an espresso shot with a dense golden brown foam) can be primarily increased.

As shown in an exaggerated sectional view in the one-dot chain line circles in Fig. 10B, the bubble increasing portion 41 in the form of a through hole has a first passing portion 41a, a first holding portion 41b, (41c), a second retention part (41d), and a third passage part (41e) are continuously formed from the upper part to the lower part,

The espresso produced by extracting the powdered coffee while the hot water is pressurized and supplied by the pump passes through the bubble increasing portion 41 by the specific discharge pressure,

The flexible foam expanding body 40 vibrates due to the vibration transmitted from the motor that operates the pump of the coffee maker

The liquid espresso has a narrow first passage portion 41a, an extended first stay portion 41b, a narrow second passage portion 41c, an extended second stay portion 41d, a narrow third passage portion 41e, And the bubbles increase.

The size of the relative cross-

(The second passing portion 41c, the first passing portion 41a, the third passing portion 41e, the first staying portion 41b, the third passing portion 41e)

(The second passing portion 41c> the third passing portion 41e? The first passing portion 41a> the third passing portion 41e? The first staying portion 41b)

Crema was found to be the most abundant.

Next, the screen 20 has a powdered coffee receiving portion 20a, a flange 23 on the outside of the upper portion thereof, a support tab 25 on the inside thereof, and an extraction hole 21, The extraction holes 21 are arranged at the outsides of the bottom surface and arranged at positions displaced with respect to the center portion hot water injection hole 102 of the sealing cover 100 and more preferably arranged at the greatest possible distance, Espresso is extracted as much as possible after contact with powdered coffee.

Especially, the extraction hole 21 presses the bottom surface of the sieve 20 made of SUS material to prevent corrosion of metal, in particular, to form an upward protrusion 21A. The vertex of the upward protrusion is polished, 21), the extraction hole is formed as small as possible,

The extraction hole 21 formed at the vertex of the upward protrusion 21A is not blocked by the powdered coffee (because the powder coffee flowing by the hot water in the upward protrusion 21A does not stay and slides along the upward projection) , So that the direct contact time between the powdered coffee particles and the extraction hole is short).

In addition, a recess 21a is formed in the bottom surface of the sieve 20, which is the opposite side of the sieve 21 due to the upward protrusion 21A. When water flowing from the bottom of the sieve 20 contacts the sieve 21, Coffee particles can also be easily separated and removed.

In addition, a resistance protrusion 27 is protruded inside the upward protrusion 21A of the outer portion, which is also press-formed by press working, and a groove 27a is formed on the opposite surface.

The resistance protrusions 27 are in contact with the coffee particles flowing by the hot water to make the flow characteristics of the coffee particles irregular and complicated to increase the extraction performance,
