Referring to the drawings, the dewaterable mixer according to an embodiment of the present invention includes a mixer body and the inner cylinder unit.

Here, the mixer body 100 has an outer cylinder 110, a grinding blade 120, and a blade driving unit 130.

In detail, the outer cylinder 110 is blocked from the bottom to allow the mixing object to be accommodated therein, and has an open upper opening structure, and is configured to be opened and closed by the mixer cover 140.

In addition, the outer cylinder 110 may be closed by being covered with an outer cylinder cover 110a at the top before being seated in the barrel support case 300 to be described later, the outer cylinder cover (110a) to the vacuum unit 400 to be described later The suction hole may be formed to form a vacuum of the outer cylinder 110.

In addition, when the juice of the mixing object comes out through the dehydration hole 210b of the inner cylinder 210 by the dehydration process of the mixing object to be described later, the juice can be removed without separating the outer cylinder 110 from the barrel support case 300. In order to be able to do this, the discharge portion (not shown) inclined downward may be formed at the lower side portion of the outer cylinder 100.

At this time, the mixing object refers to the food to be pulverized by the operation of the blender to produce juice.

In addition, the grinding blade 120 is disposed in the inner cylinder 210, and serves to liquefy by grinding the mixing object in the inner cylinder 210 during rotation.

In addition, the blade drive unit 130 is configured to rotate the grinding blade (120).

In addition, the outer cylinder 110 is supported by the barrel support case 300, the barrel support case 300 as a whole takes the shape of the letter C as shown in the figure.

The barrel support case 300 has a lower casing portion 310 positioned below the outer cylinder 110 and a side casing portion 320 extending upward from the lower casing portion 310 and connected to the mixer cover 140. )

Specifically, the barrel support case 300 is the outer casing 110 is seated on the upper surface of the lower casing portion 310 disposed in the transverse direction, the side portion extending in the upper direction from the lower casing portion 310 is disposed in the longitudinal direction The upper end of the casing portion 320 is hinged to the mixer cover 140 is rotated up and down.

The barrel support case 300 is installed inside the blade driving unit 130 and the inner cylinder driving unit 220 which will be described later, when the outer cylinder 110, the inner cylinder 210 is built, the grinding is located in the inner cylinder 210 The blade 120 and the blade driver 130 installed in the barrel support case 300 are connected to each other so that a driving force is transmitted, and the inner cylinder drive unit 220 installed in the inner cylinder 210 and the barrel support case 300 installed in the outer cylinder 110. Are connected to each other so that the driving force is transmitted.

More specifically, the outer cylinder 110 is detachably connected to the barrel support case 300. For example, the outer circumferential surface of the lower protrusion 110b of the outer cylinder 110 is formed with a spiral protrusion fitted to the barrel support case 300, the seating groove of the barrel support case 300 on which the lower protrusion 110b is seated ( 300a) The inner circumferential surface is formed with a spiral groove, the projection is fitted into the groove, the outer cylinder is mounted on the barrel support case 300, it can be removed by releasing the contrary.

In addition, the outer cylinder 110 includes a plurality of intermediate rotary shafts for transmitting the driving force transmitted from the outside to each of the grinding blade 130 and the inner cylinder 120 disposed therein. Specifically, the outer cylinder 110 includes a first intermediate rotation shaft 121 and a second intermediate rotation shaft 211 surrounding the first intermediate rotation shaft 121.

Here, the first intermediate rotary shaft 121 has a structure capable of transmitting power to the grinding blade 130 by receiving power from the blade drive motor 132 disposed in the barrel support case 300, As an example, the lower part may be keyed with the blade rotation shaft 131 of the blade driver 130, and the upper part may be keyed with the grinding blade 130.

The second intermediate rotation shaft 211 has a structure capable of transmitting power to the inner cylinder 120 by receiving power from the inner cylinder driving motor 222 disposed in the barrel support case 300. The inner cylinder rotating shaft 221 of the inner cylinder driving unit 220 is keyed, the upper portion may be keyed with the inner cylinder 120.

In this case, a bearing may be disposed between the first intermediate rotation shaft 121 and the second intermediate rotation shaft 211 so as to be rotated independently of each other.

On the other hand, the inner cylinder unit 200 has an inner cylinder 210 and the inner cylinder driving unit 220.

Here, the inner cylinder 210 is installed in the outer cylinder 110, the inner cylinder cover 210a may be closed by covering the upper portion before being seated in the barrel support case 300, such an inner cylinder cover 210a will be described later A suction hole may be formed to form a vacuum of the inner cylinder 210 by the vacuum unit 400.

In addition, at least one protrusion 213 may be formed on the inner side of the inner cylinder 210 so that the mixing object that is rotated and flows while being crushed by the grinding blade 120 may be caught.

When the grinding blade 120 is rotated in the state in which the mixing object is accommodated in the inner cylinder 210, when the mixing object hits the protrusion 213 formed on the inner side of the inner cylinder 210 rotating in the opposite direction, it occurs accordingly. The turbulent flow of the mixing object is increased to increase the grinding effect of the mixing object.

In addition, the mixing object flows upward while being radially pushed radially by centrifugal force by the rotation of the grinding blade 120, and the protrusion 213 of the protrusion having the shape of a screw protrusion that induces the downward helical flow of the mixing object is inside the inner cylinder 210. By being configured on the side, as the mixing object flows toward the grinding blade 120 disposed below the inner cylinder 210, the grinding effect of the mixer can be further increased.

In addition, the controller (not shown) performs a repetitive operation of rotating the inner cylinder 210 in the opposite direction to the grinding blade 120, or rotating and stopping the inner cylinder 210 for irregular flow of the mixing object of the inner cylinder 210. The inner cylinder driving motor 222 of the inner cylinder driving unit 220 to be described later may be controlled.

Further, the inner cylinder 210 is formed with a plurality of dehydration holes 210b for performing the dehydration process so that only the juice can be extracted from the mixing object ground by the grinding blade 120.

At this time, although the dehydration hole 210b is largely illustrated in the drawing, in reality, a very small hole through which only the juice of the mixing object can be taken out may be formed in a plurality of mesh structures on the side of the inner cylinder 210. Furthermore, the dehydration hole 210b may be formed directly on the side of the inner cylinder 210 as shown in the drawing, and although not shown in the drawing, a separate member, for example, a mesh member, has a side of the inner cylinder 210. It may take a mounted structure to be a part of.

In addition, the dehydration hole (210b) may be formed in the lower portion or the side of the inner cylinder 210, at this time it is preferably formed on the side without being formed in the lower portion, and more preferably formed from a predetermined height or more in the side portion. This is because the mixing effect is increased when there is a certain amount of liquid (eg, separate water or juice generated when mixing) when mixing the mixing object.

Of course, even if the dehydration hole (210b) is formed from a predetermined height or more on the side of the inner cylinder 210, when dehydrating the mixing object, because the inner cylinder 210 rotates at a much faster speed than when grinding, juice is the inner cylinder As it moves more easily up the inner side of the 210, the juice can be sufficiently escaped to the outside of the inner cylinder 210 through the dehydration hole (210b).

In addition, the inner cylinder driving unit 220 is configured to rotate the inner cylinder 210.

In detail, the inner cylinder driving unit 220 includes an inner cylinder rotating shaft 221, an inner cylinder driving motor 222, and an inner cylinder driving connector 223.

The blade drive unit 130 described above includes a blade rotation shaft 131, a blade drive motor 132, and a blade drive connector 133.

Here, the inner cylinder rotating shaft 221 is connected so that the rotational driving force is transmitted to the lower portion of the inner cylinder 210 built in the outer cylinder 110 when the outer cylinder 110 is seated in the barrel support case 300, the blade rotating shaft ( 131 is connected so that the rotational driving force is transmitted to the lower portion of the grinding blade 120 embedded in the inner cylinder 210 when the outer cylinder 110 is seated in the barrel support case 300.

At this time, the blade rotating shaft 131 is installed to be axially rotated in the hollow formed in the inner cylinder rotating shaft 221, and forms a structure in which the blade rotating shaft 131 and the inner cylinder rotating shaft 221 independently of each other.

That is, a bearing is provided in the hollow of the inner cylinder rotating shaft 221 so that the blade rotating shaft 131 penetrates, and the blade rotating shaft 131 can be independently rotated in the inner cylinder rotating shaft 221.

On the other hand, the inner cylinder driving unit 220 has a structure in which the gear coupling structure of the inner cylinder driving connecting portion 223 is variable so that the inner cylinder 210 has different rotational speeds during grinding and dehydration of the mixing object.

That is, in the case of dehydration after pulverizing the mixing object with a blender, the inner cylinder 210 is rotated faster than when pulverizing, as juice must be extracted from the pulverized mixing object (dehydration). In the grinding of the mixing object, the inner cylinder 210 has a slower rotational speed than the dehydration of the mixing object, and when the mixing object is dehydrated, the inner cylinder 210 has the higher rotational speed than the grinding. Form a structure.

Accordingly, the present invention raises the torque while lowering the reverse rotational speed of the inner cylinder 210 when the mixing object is pulverized, and the mixing object closer to the inner side surface of the inner cylinder 210 among the mixing object that is rotated forward by the forward rotation of the grinding blade. It can be smoothly reverse rotation, when dehydrating the pulverized mixing object can maximize the dehydration effect by raising the rotation speed of the inner cylinder 210 as much as possible than when the mixing object is crushed.

Specifically, the inner cylinder drive connecting portion 223, the drive gear 223b and the drive gear 223c is installed on the inner cylinder driving shaft 223a connected to the inner cylinder driving motor 222, the inner cylinder rotating shaft 221 or A driven large gear 223e and a driven small gear 223f are installed in the intermediate rotating shaft 223d which is interlocked with the inner cylinder rotating shaft 221.

Here, the inner cylinder drive shaft 223a and the inner cylinder rotating shaft 221 are disposed in parallel with each other, and as an additional driving force transfer medium in the middle when transferring the driving force from the inner cylinder driving shaft 223a to the inner cylinder rotating shaft 221, for example, The rotating shaft 223d may be disposed in parallel with the inner cylinder driving shaft 223a and the inner cylinder rotating shaft 221.

In this case, the driven large gear 223e and the driven small gear 223f may be directly installed on the inner cylindrical rotating shaft 221, and may be installed on the intermediate rotating shaft 223d as shown in the drawing. It will be described with an example installed on the intermediate rotary shaft (223d).

Thus, the arrangement of the driven large gear 223e and the driven small gear 223f to be described later includes the inner cylindrical rotating shaft 221 when the driven large gear 223e and the driven small gear 223f are directly installed on the inner rotary shaft 221. Of course)

The drive gear 223b and the drive gear 223c are spaced apart from each other along the axial direction on the inner cylinder drive shaft 223a, and the driven gear 223e and the driven gear 223f are intermediate rotation shafts 223d. Are spaced apart from each other along the axial direction.

At this time, the drive gear 223b of the inner cylinder drive shaft 223a corresponds to the driven standby gear 223e of the intermediate rotary shaft 223d, and the drive standby gear 223c of the inner cylinder drive shaft 223a corresponds to the intermediate rotary shaft 223d. In order to correspond to the driven gear 223f, the drive gear 223b and the drive gear 223c are sequentially arranged on the inner cylinder drive shaft 223a, and the driven gear 223e and the driven gear 223f are intermediate rotation shafts. It is arranged in order at 223d.

As an example, as shown in the drawing, the drive gear 223b and the drive standby gear 223c are arranged in the upward direction from the inner cylinder drive shaft 223a, and the driven standby gear 223e and the driven small gear 223f are shown. Is arranged in the upward direction from the intermediate rotation shaft 223d.

For reference, as the meaning of each component is implied, the drive gear 223b has a smaller diameter than the drive gear 223c, and the driven gear 223e is the driven gear 223f. More relatively larger in diameter.

The inner cylinder drive connecting portion 223 configured as described above has the drive standby gear 223c and the longitudinal axis when the inner cylinder drive shaft 223a reciprocates in the axial direction, and the drive gear 223b and the driven standby gear 223e are geared. When the all-gear gear 223f is non-geared and the driving gear 223c and the driven gear 223f are geared, the driving gear 223b and the driven gear 223e may be non-geared. have.

That is, when the mixing object is pulverized, the inner cylinder drive shaft 223a is axially moved downward, as shown in FIG. 3, so that the drive standby gear 223c and the driven gear 223f are gear-fastened, so that the inner cylinder 210 is crushed. As it is decelerated but rotates with a large torque, it can rotate smoothly in the opposite direction to the grinding blade.

In addition, when the mixing object is dewatered, as shown in FIG. 4, the inner cylinder drive shaft 223a is axially moved downward, so that the driving standby gear 223c and the driven gear 223f are geared together, thereby crushing the mixing object. As the inner cylinder 210 rotates at a relatively faster speed than when dehydrated, juice dewatering from the pulverized mixing object can be effectively performed.

Further, although the inner cylinder drive connecting portion 223 is not shown in the drawing, the inner cylinder driving shaft 223a does not reciprocate in the axial direction, and the intermediate rotation shaft 223d reciprocates in the axial direction, and the drive gear 223b. Drive gear 223c and driven gear 223f are non-geared when the driven gear 223e is engaged with the gear, and drive gear 223c and driven gear 223f are geared when the gear is engaged. 223b and driven standby gear 223e may have a non-geared structure.

And, although not shown in the drawings, when the driven standby gear 223e and the driven small gear 223f are directly installed on the inner cylinder shaft 221, of course, the inner cylinder shaft 221 is axially moved.

On the other hand, the inner cylinder drive connecting portion 223 may include a shaft moving member 223g for axially moving the inner cylinder driving shaft 223a, wherein the shaft moving member 223g utilizes any conventional driving member such as a solenoid cylinder. Of course it can be.

Here, the inner cylinder drive shaft 223a is keyed to one end is coupled to the motor shaft 222a of the inner cylinder drive motor 222 axially rotationally slidably axially movable, the other end is the shaft moving member (223g) It can be connected to the axis rotatably.

That is, the inner cylinder driving shaft 223a is keyed so that one end thereof is axially rotated interlocked with the motor shaft 222a of the inner cylinder driving motor 222, so that the inner cylinder driving motor 222 operates to rotate the motor shaft 222a. As the shaft rotates in conjunction with the shaft, the rotary driving force is received from the inner cylinder driving motor 222.

In addition, the inner cylinder drive shaft 223a is slidably axially movable to the motor shaft 222a of the inner cylinder drive motor 222, so that the motor shaft (22) may move even when the shaft is moved in the axial direction by the shaft moving member 223g. And maintain a keyed state for 222a).

As an example, the motor shaft 222a has a square cross section of the hollow 222b, and the inner cylinder drive shaft 223a has a cross section at one end thereof combined with the cross section of the hollow 222b of the motor shaft 222a, thereby forming an inner cylinder drive shaft 223a. The key may be slidably axially movable while one end of the key is axially coupled to the motor shaft 222a.

In addition, the inner cylinder drive shaft 223a is connected to the shaft moving member 223g by the other end connected to the shaft moving member 223g so as to be axially rotatable, even when moved in the axial direction by the shaft moving member 223g. Can be rotated with

As an example, the inner cylinder drive shaft 223a may be connected to the other end of the inner shaft driving member 223g by an axial rotation bearing 223h.

On the other hand, the inner cylinder drive connecting portion 223 may be configured so that the rotational speed of the inner cylinder 210 when dewatering the mixing object, more than five times faster than the rotational speed of the inner cylinder 210 when grinding the mixing object.

As a specific example, the inner cylinder drive connecting portion 223 is configured such that the inner cylinder 210 is 50rpm to 350rpm when grinding the mixing object, the inner cylinder 210 is 1500rpm to 3500rpm when the dehydration of the mixing object.

By the configuration of the inner cylinder drive connecting portion 223, the present invention can raise the torque as much as possible by lowering the rotational speed of the inner cylinder 210 when grinding the mixing object, the rotational speed of the inner cylinder 210 when dehydrating the mixing object You can maximize the dehydration effect by raising the maximum.

It is possible to smoothly reverse the mixing object close to the inner side of the 210, the rotation speed of the inner cylinder 210 when the mixing object is crushed using another inner cylinder drive motor 228 when dehydrating the mixing object. By raising the maximum, the dehydration effect can be maximized.

Specifically, one inner cylinder drive motor 228 is the first motor (M1) for supplying a rotational driving force to the inner cylinder 210 during the grinding of the mixing object, the other inner cylinder driving motor 228 when dehydrating the mixing object It is a second motor (M2) for supplying a rotational driving force to the inner cylinder 210 in the direction opposite to the first motor (M1).

It serves to axially rotate the gear (229g) and the inner cylinder rotation shaft 221.

That is, the second one-way bearing 229h has an inner cylindrical shaft from the second driven gear 229g such that the second driven gear 229g rotates in the other direction in conjunction with the inner cylinder rotating shaft 221 when the second driven gear 229g rotates in the other direction. The driving force is transmitted to the 221, and the second driven gear 229g from the inner cylinder rotation shaft 221 so that the second driven gear 229g does not rotate in the opposite direction when the inner shaft rotation shaft 221 rotates in the opposite direction. ) So that the driving force is not transmitted.

Here, the first one-way bearing 229d and the second one-way bearing 229h have a structure in which driving force is transmitted only in opposite rotation directions.

Accordingly, when only the first motor M1 is operated, even if the first driven gear 229c rotates through the first drive gear 229a, the second driven gear 229g is non-rotated, and thus the second motor ( Without affecting M2), even if the second driven gear 229g rotates through the second drive gear 229e when only the second motor M2 is operated, the first driven gear 229c is non-rotated and is eventually driven. This does not affect the first motor M1.

By the configuration of the first motor (M1), the second motor (M2) and the inner cylinder drive connecting portion 229, the present invention can raise the torque as much as possible by lowering the rotational speed of the inner cylinder 210 when grinding the mixing object , When dehydration of the mixing object, it is possible to maximize the dehydration effect by increasing the rotation speed of the inner cylinder 210 as much as possible.

Meanwhile, the mixer according to the present invention may further include a vacuum unit 400 configured to form a vacuum in the inner cylinder 210 as shown in FIGS. 2 and 5.

The vacuum unit 400 may include a suction pipe and a vacuum driver 410.

Here, the suction pipe is formed inside the outer cover, and the outer cover covers the outer cylinder 110 and communicates with the outer cylinder 110 when closed, and at the same time has a structure in communication with the inner cylinder 210 disposed in the outer cylinder 110 I can have it.

In addition, the vacuum driving unit 410 is connected to the suction pipe, it may be made of a vacuum motor and a vacuum pump.

The mixer of the present invention allows the mixing operation including the grinding operation and the dehydration operation to be performed under vacuum by the vacuum unit 400 configured as described above, so that the mixing operation including fruits or vegetables is not oxidized. As a result, fresh, nutrient-free juices can be obtained.

As a result, the dewaterable mixer according to the present invention has a structure in which the gear fastening structure of the inner cylinder drive connecting portion 229 is varied so that the inner cylinder 210 has different rotational speeds during grinding and dehydration of a mixing object. Alternatively, as the inner cylinder driving motor 228 is configured in plural, when the mixing object is crushed, the inner cylinder 210 is increased from the mixing object rotated forward by the forward rotation of the grinding blade while lowering the reverse rotational speed of the inner cylinder 210. It is possible to smoothly reverse the mixing object close to the inner side of the 210, and when dewatering the pulverized mixing object, it is possible to maximize the dehydration effect by raising the rotation speed of the inner cylinder 210 as much as possible when the mixing object is crushed. .
