Technical Field

The present invention relates to a juice extracting tube and a juice extractor using the same, and more particularly, to a juice extracting tube including two modules and a juice extractor using the same.

Background

Recently, as the interest of health in households increases, the use frequency of juice extractors having a function of allowing an individual to directly extract juice from objects to be extracted such as vegetables, grains, and fruits and to eat the juice increases.

A general operation manner of such a juicer is a manner of pressing a juicing object on a wiping plate, for example, using the principle of juicing by stone-milling beans as disclosed in korean patent No. 793852.

For this purpose, the juice extractor has: a driving part for providing a rotational force; a cartridge housing having a driving shaft for receiving a rotational force from the driving part; the screw is connected with the driving shaft and is used for extruding and crushing the juicing object through the screw thread formed on the local part of the screw; and a juice extracting barrel for separating juice made by the screw. The driving part providing a rotating force to the juice extractor includes a motor and a decelerator. The motor is connected with the driving shaft and transmits rotating force to the screw. For this purpose, the drive shaft is connected to the screw through the lower part of the cartridge housing.

Generally, a juice extracting tube has a mesh structure (mesh structure) made of mesh holes. The juice extracting tube having the mesh structure is easily clogged with a juice extracting object during a juice extracting process, and thus has a problem of low juice extracting efficiency. Further, the formed mesh is dense, and thus there is a problem that it is difficult to clean the juicing object stuck in the mesh. Although various filter structures are conceivable, it is difficult to apply the filter structure to a juicer using a screw type squeezing method because the filter structure performs a simple filtering function.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, which are described in detail only for the purpose of making it easy for those skilled in the art to practice the present invention, and do not intend to limit the technical spirit and scope of the present invention.

Note that, since the respective structures shown in the drawings are arbitrarily illustrated for convenience of explanation, the present invention is not limited to the structures shown in the drawings, and the sizes and shapes of the structural elements shown in the drawings may be exaggerated for the sake of clarity and convenience of explanation.

Therefore, terms specifically defined in consideration of the structures and actions of the present invention may be different according to the intention or the custom of the user or the operator, and the meanings of the terms should be determined based on the entire contents of the present specification. Further, for the purpose of explaining the present invention, the "upper side" and "upper portion" refer to the side to which the material is put, unless there is another reason that it can be differently explained.

Fig. 1 is a perspective view of a juice extractor according to an embodiment of the present invention, fig. 2 is a longitudinal sectional view of fig. 1, fig. 3 is an exploded perspective view of fig. 1, and fig. 4 is a bottom exploded perspective view of fig. 1.

Referring to fig. 1 to 4, a juice extractor according to an embodiment of the present invention may include a main body 1, a hopper 100, a screw 300, and a juice extracting barrel 400.

The inclusion of a cartridge housing is commonly referred to as a juice cartridge, but in the juicer of the present invention, the cartridge housing and juice cartridge are described as being distinct for ease of description.

The main body 1 may include an upper support 2 and a lower support 3. A drive motor for generating a drive force and a speed reducer (not shown) for transmitting the drive force to a drive shaft are disposed inside the main body 1.

The drive motor and the speed reducer are constituted in the present embodiment, but may be constituted by a low-speed motor.

The upper support 2 may be formed in a shape corresponding to the outer circumferential surface of the cartridge case 200 so as to support the lower portion of the cartridge case 200.

The lower support 3 may be formed in a plate shape extending to one side at a lower portion of the body 1. A residue cup (not shown) for containing the residue may be disposed on the lower supporting portion 3.

The speed reducer performs a function of converting high-speed rotation of the drive motor into low-speed rotation, and may be disposed inside the upper support 2.

The hopper 100 is configured to temporarily accommodate a juicing object (for example, vegetables, grains, fruits, etc.) and guide the juicing object to the juicing barrel 400, and the hopper 100 is detachably coupled to the barrel housing 200.

The cartridge case 200 is provided in a substantially cylindrical shape having an open upper surface and an internal space, and is attached to an upper portion of the main body 1. Further, a juice outlet 220 is formed at one side, and a residue outlet 230 is formed at the other side.

The juice extracting cylinder 400 and the screw are disposed in the inner space, and the hopper 100 is coupled to the open upper surface.

The cartridge housing 200 is a core structure of the present invention together with the juice extracting cartridge 400, and a detailed description thereof will be made after the juice extracting cartridge 400.

The lower side of the screw 300 is connected to a driving shaft 6 of a driving motor, and the upper side is coupled to a coupling portion 110 provided in the hopper 100, and the driving shaft 6 receives a rotational force generated from the driving motor to perform a rotational motion, thereby squeezing or pulverizing the objects to be juiced.

When the screw 300 is disposed inside the juice extracting tube 400 described later, the space (space) between the screw and the juice extracting tube 400 is formed to be narrower toward the lower portion up to a predetermined point.

Further, a plurality of screw flights 310 are formed at a portion of the screw 300 that contacts the juice extracting barrel 400. The screw flight 310 causes the juice to be squeezed into a gap (space) formed between the screw 300 and the juice extracting tube 400, and the juice is transferred to the lower side.

Also, as for the width of the screw flight 310 formed on the screw 300, a single screw flight is formed on the upper side, thereby having a relatively wide interval. Also, a plurality of screw threads 310 are formed at a lower side so as to have a relatively narrow interval.

That is, the function of crushing the object to be juiced is performed on the upper side, and the function of crushing and squeezing the object to be juiced is performed on the lower side. Thus, in the process of moving the object to be juiced downward from the upper side by the rotation of the screw 300, the object to be juiced is juiced between the screw thread 310 and the inner side surface of the inner block 10, which will be described later.

The juice extracting barrel 400 is a core structure of the present invention, and has a hollow cylindrical or truncated cone shape, and can extrude or crush a juice extracting object by an interaction with the screw 300.

Fig. 5 is a perspective view of the juice extractor of fig. 3, and fig. 6 is a bottom perspective view of the juice extractor of fig. 3. Referring to fig. 5 and 6, the juice extractor 400 may include an inner module 10 and an outer module 20. Furthermore, the juice extracting cartridge 400 may be constructed by combining the inner block 10 and the outer block 20.

Here, the inner module 10 and the outer module 20 may be formed of a material such as Polyetherimide (PEI).

The inner block 10 has a substantially cylindrical shape, and the upper and lower sides thereof are openable. Here, the inner module 10 includes a plurality of inner plates 11, and a plurality of slits 12 are formed through the plurality of inner plates 11.

Here, the plate portions are named for convenience of explanation of the present invention, and when the cylindrical module is divided into the slit-formed hole portions and the slit-not-formed plate portions, the slit-not-formed plate portions are defined as "plate portions".

When the screw 300 is accommodated in the juice extractor, the slit 12 is not limited to a bar-shaped hole or an egg-shaped hole as long as it is a hole intersecting the thread of the screw 300.

As for the slits 12, the width of the slits 12 on the upper side may be smaller than the width of the slits 12 on the lower side. That is, the width of the slit 12 may be narrower toward the upper side.

Also, a stepped portion 121 may be formed on the slit 12. The width of the slits 12 on the upper side may be smaller than the width of the slits 12 on the lower side with respect to the step portion 121.

Also, a first rib 13 may be formed to protrude on the inner circumferential surface of the inner panel portion 11. In the present embodiment, the first rib 13 is formed in a protruding band shape, but may be deformed into any shape that abuts against the screw thread.

The first ribs 13 press or crush the material by interacting with the screw threads 310 as the screw 300 rotates.

Without the first rib 13, the objects to be juiced may not move downward to be stagnated, or the pressing force or the pulverizing force is weak or may not occur.

In the edge of the first slit 12 formed in the up-down direction, the first rib 13 may be formed to protrude radially inward.

The height of the first rib 13 may be set to be longer than the width (or amplitude) of the slits 12.

Further, a second rib 14 protruding in the longitudinal direction may be formed on the inner side surface of the inner panel portion 11.

The second ribs 14 may perform a function of enhancing rigidity of the inner module 10 and may perform a function of guiding the objects to be juiced to the inside of the juice extracting tub 400.

Also, the second rib 14 may perform a function of adjusting the position of the screw 300 and adjusting the juicing space.

The second ribs 14 perform a function of transferring a material put into the juice extracting tub 400 to a lower portion and crushing a juice extracting object.

For this, the second ribs 14 may be vertically formed in the up-down direction on the inner circumferential surface of the inner module 10 (or the inner side surface of the inner panel part 11).

The protruding height of the second rib 14 may be set to have the same height from the upper portion to the lower portion of the inner module 10, but may preferably be set to be gradually lower from the upper portion to the lower portion of the inner module 10.

Also, the second rib 14 may be formed to be inclined downward from the upper portion to the lower portion of the inner module 10, and may be formed at a middle portion thereof with a step portion 14-1 protruded to the screw 300 to form a step.

The position, number or protrusion height of the stepped portion 14-1 may be variously modified according to the shape of the screw 300 and the design condition of the screw flight 310.

The number and arrangement of the second ribs 14 may be variously changed as necessary in consideration of design conditions and juicing efficiency.

In the embodiment of the present invention, the example in which the second rib 14 is formed to be vertically formed along the vertical direction of the inner module 10 has been described, but the scope of the present invention is not limited thereto.

That is, the second ribs 14 may be formed to intersect with the screw flight 310 of the screw 300 and have a predetermined slope, so that the objects to be juiced are crushed while being transferred downward by the interaction of the screw 300 and the second ribs 14 of the inner block 10.

In addition, the operation according to the formation lengths of the first rib 13 and the second rib 14 will be described.

The first ribs 13 are used to perform the following functions: that is, the juice extracting object transferred to the lower portion by the rotation of the screw 300 accommodated in the inner block 10 is finely and uniformly secondarily pulverized in cooperation with the screw 300.

For this reason, the first ribs 13 are formed on the lower inner surface of the inner panel 11. That is, the first rib 13 may be formed to have a length in the up-down direction shorter than that of the second rib 14.

As a result, the second ribs 14 are formed on the inner side surface of the inner panel portion 11 over the entire region from the upper portion to the lower portion; the first ribs 13 are formed only to a set height in the lower portion of the inner panel portion 11.

If the first ribs 13 are formed in the middle portion of the inside of the inner plate 11, the material is finely crushed in the middle portion of the inner plate 11 by the first ribs 13 and the screw 300, the particle size of the object to be juiced is sharply reduced, and the object to be juiced is not caught by the second ribs 14 in the lower portion of the inner plate 11 and rotates together with the screw flight 310 of the screw 300.

Therefore, the object to be squeezed cannot be smoothly transferred downward along the screw flight 310 of the screw 300, and the object to be squeezed stays inside the inner plate 11.

If the object to be juiced stagnates inside the inner panel portion 11, stagnation of the object to be juiced becomes more serious due to the object to be juiced being further thrown in, and the object to be juiced must be forcibly pressed and thrown in using another tool, which is inconvenient.

In order to prevent such a problem, the first ribs 13 according to the embodiment of the present invention are formed at the lower portion of the inner plate 11, so that the size of the juicing object does not change rapidly but changes stepwise, and thus the juicing object can be smoothly transferred to the lower side by the screw threads 310 and the second ribs 14, and the juicing object can be more finely pulverized by the first ribs 13 at the lower portion of the inner plate 11.

Further, the first ribs 13 are formed at the lower portion of the inner plate 11, so that the pressure of the object dregs to be squeezed against the inner plate 11 and the screw 300 is gradually increased in the process of smoothly transferring the object to be squeezed from the upper portion to the lower portion of the inner plate 11 by the screw 300 and the second ribs 14. Due to such pressure, juice extracted from the object of juice extraction can be smoothly discharged through the gap formed between the slit 12 of the inner block 10 and the rib 22 of the outer block 20.

Also, as the primarily pulverized juice extracting object is transferred to the lower portion to be pulverized more finely by the first ribs 13 formed at the lower portion of the inner plate portion 11, the dregs of the juice extracting object are strongly pressed due to the increased pressure between the screw 300 and the inner plate portion 11, the juice generated at this time is pushed upward, and the juice is discharged through the gaps formed between the slits 12 of the inner block 10 and the ribs 22 of the outer block 20, thereby improving the juice extracting efficiency.

Thereby, when the inner block 10 is coupled with the outer block 20, a gap is formed, which is formed to be gradually enlarged toward the radial outside, and thus, juice can be smoothly discharged. Further, the cross section of the inner plate portion 11 may be semicircular or trapezoidal.

In addition, the plurality of inner panel portions 11 may include inner panel portions 11 having a relatively narrow width and inner panel portions 11 having a relatively wide width.

That is, in order to fix the coupling position of the inner module 10 and the outer module 20, a space in which the interval between the plurality of ribs 22 is relatively narrow and a space in which the interval is relatively wide may be formed. A space having a relatively wide interval between the plurality of ribs 22 may be inserted into the inner panel part 11 having a relatively wide width.

Also, the first rib 13 may be formed on the inner side surface of the inner panel part 11 having a relatively narrow width, and the second rib 14 may be formed on the inner side surface of the inner panel part 11 having a relatively wide width.

The cross section of the inner plate portion 11 may have a shape that widens toward the radially inner side of the inner module 10.

Further, a step 111 for engagement is formed below the inner plate 11, and an annular inner flange 16 is formed radially inward.

The step 111 for engaging is configured to be coupled to an engaging end 211 formed on an outer flange 27 of the outer module 20, which will be described later, and performs a function of fixing the coupling of the inner module 10 and the outer module 20.

The inner flange 16 supports the plurality of slits 12 formed in the inner plate 11 so as to have a constant width, and therefore the width of the slits 12 can be kept from being changed during juicing.

Further, since the upper surface of the inner flange 16 is formed to be inclined downward radially outward, juice can be easily discharged and the juice extracting efficiency can be improved.

Although the dregs are immediately discharged downward when the lower end of the inner module 10 is completely opened, the dregs are temporarily stagnated if the inner flange 16 is formed at the lower end of the inner module 10, and thus the juice extracting efficiency can be further improved.

In the present embodiment, the inner flange 16 is described as being formed inside the engaging step 111, but the inner flange 16 may be directly joined to the inner surface of the inner plate portion 11.

Further, a coupling protrusion 19 is formed at a lower portion of the inner plate portion 11, and the coupling protrusion 19 penetrates a coupling groove 29 of an outer module 20 described later and is supported by a bottom plate surface of the tube case 200.

The coupling protrusion 19 may be formed to protrude toward the lower side of the inner flange 16, or may be formed as a groove recessed upward.

Also, a spiral guide rib (18 in fig. 7) may be formed toward the center on the upper surface of the inner flange 16.

In this case, on the upper surface of the inner flange 16, a spiral guide rib 18 is formed extending from the second rib 14 toward the central portion of the inner module 10 so that the dross can be accurately guided to be discharged downward after being caught.

The spiral guide rib 18 may be formed to extend from the second rib 14 and may be formed to be inclined at a prescribed angle to the rotation direction of the screw 300.

That is, the crushed dregs of the juicing object between the screw 300 and the inner module 10 are moved downward by the first rib 13 and the second rib 14, and the guide ribs 18 formed as inclined protrusions perform a function of guiding the dregs to the dregs discharge port so that the dregs can be smoothly moved to the dregs discharge port 230 of the cylindrical housing 200.

In addition, a key groove 15 may be formed in a part of the outer surface of the inner panel portion 11. The key groove 15 is sandwiched by key protrusions 25 formed on the inner surface of the outer plate 21, which will be described later, so that the coupling positions therebetween can be fixed.

Next, the outside module 20 will be explained. The outer module 20 has a substantially cylindrical shape, and includes an outer plate 21 having an open upper and lower side, and a rib protruding from an inner surface of the outer plate 21.

The outer plate portion 21 is formed to be detachable (detachable) while accommodating the inner module 10 therein. That is, the outside module 20 is coupled to the inside module 10 so as to surround and accommodate the inside module 10 when coupled to the inside module 10. At this time, the outside module 20 can wrap and support the inside module 10.

The rib 22 is inserted into the slit 12 of the inner module 10 and forms a gap with the slit 12, and the rib 22 may be formed to protrude from the inner side surface of the outer panel 21.

In the present embodiment, the rib is formed in a strip shape elongated in one direction, but the shape is not limited if the slit 12 of the inner module 10 can be inserted and formed as a slit. Meanwhile, the rib 22 may be formed independently and coupled to the outer plate portion 21.

At this time, in order to make the width of the rib 22 narrower toward the upper side, the width of the rib 22 on the upper side may be smaller than the width of the rib 22 on the lower side.

Further, a stepped portion 24 is formed on the rib 22, and the width of the rib 22 on the upper portion side may be smaller than the width of the rib 22 on the lower portion side with reference to the stepped portion 24.

Further, a plurality of juice discharge holes 23 may be formed in the outer plate portion 21 along the outer surface.

Here, the bottom plate surface of the juice discharge hole 23 is formed to be inclined downward toward the outside in the radial direction, so that juice can be easily discharged and the juice extracting efficiency can be improved.

In addition, a support protrusion 26 may be formed on the upper side of the outer plate portion 21. The support protrusion 26 may be installed in a support groove (210 of fig. 3) formed on the inner circumferential surface of the cartridge case 200.

By fitting the support projection 26 into the support groove 210, the outer surface of the outer block 20 is supported in a state of being spaced apart from the inner surface of the cylinder case 200, and the outer block 20 can be fixed without rotating in the rotational direction in accordance with the rotational force of the screw 300.

Here, the support protrusion 26 may be formed in a shape of supporting at least two points in order to prevent the rotation of the outer module 20.

In the present invention, four support protrusions 26 are formed at equal intervals in the circumferential direction in a plan view for stable coupling of the support protrusions 26, and the support grooves 210 of the cartridge case 200 are formed in the same number at positions corresponding to the support protrusions 26.

Moreover, the support projection 26 is formed on the upper outer peripheral surface in particular in the upper side of the outer plate portion 21. Accordingly, when the user disposes the outer module 20 inside the cylinder case 200, the support groove 210 can be easily recognized with the naked eye of the user, thereby improving the assemblability.

At the same time, the support projections 26 are fitted into the support grooves 210, whereby the outer module 20 can be fixed, and the assemblability can be significantly improved.

Further, a key protrusion 25 to be inserted into the key groove 15 of the inner block 10 by means of insertion coupling, sliding coupling, or the like is formed on the inner surface of the outer plate portion 21.

The key groove 15 and the key protrusion 25 are inserted and coupled to each other, so that the coupling position between the inner module 10 and the outer module 20 can be fixed.

That is, the coupling position, rotation, and inclination of the inner block 10 and the outer block 20 can be restricted and the size of the gap can be maintained by the coupling of the key groove 15 and the key protrusion 25.

Also, an annular flange 27 may be formed on the lower side of the outer plate portion 21. Due to the outer flange 27, the dross cannot move directly under the inner module 10, and the dross temporarily rests on the upper surface of the outer flange 27.

That is, since the time for the juice extracting object to stay between the screw 200 and the inner block 10 is increased, the juice extracting object can be sufficiently pressed, and thus the juice extracting efficiency can be increased.

On the other hand, a coupling groove 29 through which the coupling protrusion 19 of the inner module 10 passes is formed on one side of the outer flange 27.

The size of the gap can be maintained by determining the relative position of the outer module 20 to the inner module 10 by coupling the coupling groove 29 and the coupling protrusion 19.

In the above-described coupling protrusion 19 and coupling groove 29, the protrusion may be deformed into a groove and the groove may be deformed into a protrusion, and means for fixing the inside module 10 and the outside module 20 is not limited to the above-described coupling groove and coupling protrusion.

Further, a catching end 211 is formed at a lower side of the outer flange 27. Therefore, when the outside module 20 is surrounded and coupled to the inside module 10, the catching step 111 of the inside module 10 is mounted to the catching end 211, and the outside module 10 supports the lower end of the inside module 10.

Next, a slit formed by coupling the inner block and the outer block will be described.

Fig. 7 is a coupling state diagram of fig. 5, and fig. 8 is a coupling state diagram of fig. 6. Referring to fig. 7 and 10, when the inside module 10 is received inside the outside module 20, the outside module 20 may surround and be coupled to the inside module 10.

At this time, the slit 12 between the inner plates 11 can be inserted with the rib 22 protruding from the inner surface of the outer plate 21 to form a predetermined gap a. Here, the size of the gap a may be constant or not. The slit a may be formed to communicate with a partitioned space b described later.

The slit a is formed to be widened toward the outer side in the radial direction, and therefore, juice can be smoothly discharged.

The slit a may be formed to be narrower from the upper side to the lower side because the upper side slit a1 is formed to be larger than the lower side slit a2 in the longitudinal direction. That is, since a greater pressure is applied to the lower side of the juice extracting barrel 400 during the pressing process, it is preferable to form the gap of the lower side of the juice extracting barrel 400 to be narrow.

For example, if the width of the slit 12 between the upper portions of the inner panel 11 is constant and the width of the rib 22 on the upper side of the stepped portion 24 is narrower toward the upper side, the size of the gap can be increased toward the upper side based on the stepped portion 24.

In the case where the object to be juiced is a relatively hard material such as carrot, most of the juice can be discharged from a narrow slit formed at the lower side during the squeezing process. However, when the object to be juiced is a relatively soft material such as tomato, juice can be discharged not only from the slit formed at the lower side during the squeezing process, but also from the wide slit at the upper side by the object to be juiced which has gathered in the slit formed at the lower side rising to the wide slit at the upper side. In this way, when the size of the gap a is not constant, the juice extracting efficiency can be improved for both a relatively hard object to be extracted, such as a carrot, and a relatively soft object to be extracted, such as a tomato.

The size of the gap a does not change during the juicing process, but can be kept constant. In addition, if the object to be juiced is a relatively hard object to be juiced such as carrot, the object may be caught by the gap a and stacked during the juicing process. In this case, since the object to be juiced is caught by the stepped portion 24, the object to be juiced can be prevented from being accumulated in the gap a.

Next, the partitioned space b formed by the coupling of the inner module and the outer module will be described.

Fig. 9 is a longitudinal sectional view taken along the line I-I 'of fig. 7, and fig. 10 is a longitudinal sectional view taken along the line II-II' of fig. 7. Referring to fig. 9 and 10, when the inner module 10 is accommodated in the outer module 20 and coupled, a space b may be formed between the outer surface of the inner plate 11 and the inner surface of the outer plate 21.

The partitioned space b functions as a flow path through which juice discharged through the slit a can move.

At this time, at least a part of the outer plate 21 and the inner plate 11 may be in line contact or surface contact from the upper end thereof contacting each other to a predetermined point downward, and the partitioned space b may be formed after the predetermined point. The space through which the juice can move, such as the slit a, may be formed in the portion where the at least one portion is in line contact or surface contact.

Also, the partitioned space b may be formed to be wider or the same as the lower side.

Fig. 11 is a longitudinal sectional view illustrating a coupling state of a screw with a juice extracting module, and fig. 12 is a partially enlarged view of fig. 11. Referring to fig. 11 and 12, the partitioned space is specifically described.

When the inner module 10 is vertically detachably accommodated in the outer module 20 and coupled, the inner surface of the outer plate 21 is surrounded by and coupled to the outer surface of the inner plate 11.

At this time, the outer side surface of the inner plate portion 11 is formed to be inclined by a predetermined angle a with respect to a vertical line, the inner side surface of the outer plate portion 21 is formed to be inclined by a first angle B with respect to the vertical line from the upper end of the outer plate portion 21 to a preset point, and is inclined by a second angle C with respect to the vertical line from the preset point of the outer module 20 to the bottom plate of the outer module 20.

Here, the second angle may preferably be larger than the first angle.

The angle a of the outer peripheral surface of the inner plate portion 11 is set to the same angle as the first angle B of the outer plate portion 21, and at least a part of the outer surface of the inner plate portion 11 and the inner surface of the outer plate portion 21 is in line contact or surface contact (portion denoted by "X") from the upper portion of the outer module 20 to a predetermined point of the transfer space, so that the upper portion of the inner plate portion 11 can be supported by the upper portion of the outer plate portion 21.

In this case, the angle formed by the outer surface of the inner plate 11 and the inner surface of the outer plate 21 is "0". Accordingly, when the juice is extracted from the juice extraction target by the rotation of the screw 300, the load or pressure applied to the inner block 10 is transmitted to the outer block 20, and the effect of increasing the rigidity of the inner block 10 can be obtained.

Since the inner surface of the outer plate portion 21 is formed at a second angle larger than the first angle from a predetermined point arranged in advance to the bottom plate surface of the outer plate portion 21, the angle α formed by the outer surface of the inner plate portion 11 and the inner surface of the outer plate portion 21 is larger than "0".

Therefore, a space b (see the portion denoted by "Y") is formed between the outer surface of the inner plate 11 and the inner surface of the outer plate 21. As described above, the partitioned space b functions as a flow path through which juice discharged through the slit a moves.

In this way, since the angle α formed by the outer surface of the inner plate portion 11 and the inner surface of the outer plate portion 21 is larger than "0", the partitioned space b can be formed to be wider toward the lower side. By forming the partitioned space b, a space in which juice can be discharged through the slits a and flow can be secured.

Preferably, the inner plate portion 11 is formed in a cylindrical shape having a diameter that decreases toward the lower side, so that the partitioned space b becomes wider toward the lower side.

Alternatively, a step may be formed below the inner plate 11, and the step may widen the partitioned space b toward the lower side.

As described above, the juice passing through the partitioned space b is discharged to the outside of the outer module 20 through the juice discharge hole 23, and the dregs may be discharged to the lower side of the inner module 10 between the screw 300 and the inner module 10.

Next, a cartridge housing of a juice extractor according to an embodiment of the present invention is explained.

Fig. 13 is a plan view of the cartridge case of fig. 1, fig. 14 is a partially cut perspective view of fig. 13, and fig. 15 is a plan view of the cartridge case of fig. 13 in a state of being coupled to an outer module.

Referring to fig. 1, 13 to 15, the cartridge case 200 is provided in a substantially cylindrical shape having an open upper surface and an inner space formed therein, and is mounted on an upper portion of the main body 1. The juice extracting cylinder 400 and the screw 300 are disposed in the inner space, and the hopper 100 may be coupled to the open upper surface.

A cylinder hole 260 is formed in the center of the bottom plate of the cylinder case 200. The driving shaft 6 is inserted into the cylindrical hole 260 and connected to the screw 300, and can transmit power to the screw 300.

The inner circumferential surface of the cylinder hole 260 may have a shape corresponding to the shape of the driving shaft 6 so as to be able to receive the rotational force generated in the driving motor through the driving shaft.

That is, the cartridge case 200 is installed in the main body 1 so that power of a driving shaft (not shown) receiving power of a driving motor (not shown) can be transmitted to the screw 300.

A waterproof portion 261 made of an elastic material such as a gasket may be provided around the cylindrical hole 260. That is, the driving shaft for transmitting power to the screw 300 is inserted into the cylindrical hole 260, and the leakage of the squeezed dregs or the squeezed juice to the driving shaft side can be prevented by the waterproof portion 261.

Further, a juice outlet 220 is formed at one side of the lower portion of the cartridge case 200, and a residue outlet 230 is formed at the other side.

In order to easily discharge juice, the juice discharge port 220 is formed to protrude from one side of the cartridge case 200 in a tubular shape, so that dregs can be discharged to a right lower side.

At this time, the juice outlet 220 may be opened or closed by the juice opening and closing mechanism 240, and the residue outlet 230 may be opened or closed by the residue opening and closing mechanism 250.

Further, a slag discharge groove 298 and a juice discharge groove 297 are formed in the bottom surface of the drum case 200 centering on the drum hole 260.

The slag discharge groove 298 is formed in the bottom plate surface of the cylinder case 200 in the circumferential direction radially outward from the cylinder hole 260.

Further, the juice discharge groove 297 may be formed in the circumferential direction on the bottom plate surface of the drum case 200, and may be formed at a position radially outward of the residue discharge groove 298, similarly to the residue discharge groove 298.

That is, the reject groove 298 is located radially inward of the outer module 20 and the juice groove 297 is located radially outward of the outer module 20.

Also, a juice drain coupling groove 221 for coupling the juice drain groove 297 and the juice drain 220 to each other is formed, and a slag discharge coupling groove 231 for coupling the slag discharge groove 298 and the slag drain 230 to each other is formed.

At this time, a cutting part 232 for cutting the juice discharge groove 297 and the dreg discharge groove 298 from each other is formed, so that juice and dreg can be completely separated and discharged through different discharge ports.

In addition, a plurality of coupling bosses 299 may be formed between the residue discharge groove 298 and the juice discharge groove 297 in a circumferential direction. The present invention is illustrated in a shape in which a recess is formed.

The coupling projection 299 may be inserted with the coupling protrusion 19 of the inner module 10 protruding to the lower side of the coupling groove 29 of the outer module 20.

In this way, the coupling projection 299 can be fixed to the coupling projection 19 of the inner module 10 and the coupling groove 29 of the outer module 20, so that the inner module 10, the outer module 20, and the cartridge case 200 can be integrally coupled. Accordingly, even under the pressing force caused by the rotation of the screw 300, the gap a and the partitioned space b can be maintained while preventing the inner module 10 and the outer module 20 from being damaged.

Next, an operation state of the above-described juice extractor according to an embodiment of the present invention will be described. Fig. 16 to 19 are operational state diagrams of a juice extractor according to an embodiment of the present invention.

First, juice discharge is explained. First, as shown in fig. 17, when the juice extracting material is put into the hopper 100, the screw 300 is rotated to press the material while moving the material downward, and then, as shown in fig. 18, juice is discharged through the gap a between the slit 12 of the inner block 10 and the rib 22 of the outer block 20.

Then, as shown in fig. 17, the juice discharged from the gap a between the slit 12 and the rib 22 passes through the partitioned space b formed between the inner block 10 and the outer block 20, and then is discharged between the inner circumferential surface of the cylinder case 200 and the outer surface of the outer block 20 through the juice discharge hole 23 of the outer block 20.

Next, the juice discharged between the inner circumferential surface of the cartridge case 200 and the outer surface of the outer module 20 moves downward, flows into a juice discharge groove 297 formed in the bottom plate of the cartridge case 200, passes through a juice discharge connection groove 221 connected to the juice discharge groove 297, and is discharged through the juice discharge port 220.

Next, with respect to the slag discharge, referring to fig. 19, the slag pressed between the screw 300 and the inner block 10 flows toward the slag discharge groove 298 and is discharged through the slag discharge port 230 after passing through the slag discharge connection groove 231 (see an arrow in fig. 18).

At this time, the dross cannot directly move downward of the inner block 10 due to the outer flange 27 extending radially inward from the lower end of the inner block 10, and the dross temporarily stays on the upper surface of the outer flange 27.

That is, since the time for the juice extracting object to stay between the screw 200 and the inner block 10 is increased, the juice extracting object can be sufficiently squeezed, and the juice extracting efficiency can be increased.

Next, a first modification of the juice extracting tube according to the present invention will be described. Fig. 20 is an integrated perspective view of a juice extracting barrel according to a first modification.

Referring to fig. 20, a separate space may not be formed between the outer surface of the inner plate 11 of the inner module 10 and the inner surface of the outer plate 21 of the outer module 20.

In this way, when the outer peripheral surface of the inner plate 11 is in close contact with the inner peripheral surface of the outer plate 21, even if vibration is applied to the entire juice extracting tube 400 during juice extraction, the inner block 10 is in close contact with the outer block 20, and thus the size of the gap a can be effectively kept constant.

Next, a second modification of the juice extracting tube according to the present invention will be described. Fig. 21 is a perspective view of an outside block according to a second modification, and fig. 22 is a combined perspective view of a juice extracting barrel according to the second modification.

At least one of the inner surface of the outer plate portion 21 and the outer surface of the inner plate portion 11 may be provided with a support portion 130 that supports the inner surface of the outer plate portion 21 and the outer surface of the inner plate portion 11 in close contact with each other.

In the present modification, the supporting portion 130 is formed on the inner surface of the outer plate portion 21 so as to protrude in the radial direction.

When the inner module 10 is coupled to the outer module 20, the support portion 130 is closely attached to the outer surface of the inner plate portion 11.

Therefore, even if vibration is applied to the juice extracting tub 400 during juice extraction, the support portion 130 elastically supports the inner plate portion 11 and the outer plate portion 21 in close contact with each other, and thus the size of the gap a and the separation space b formed between the inner plate portion 11 and the outer plate portion 21 can be effectively kept constant.

Although not shown, the supporting portion 130 may be formed as at least two parts that are separable from each other in a lockable manner (e.g., a manner in which a concave portion and a convex portion are coupled to each other).

In this case, a part of the separated support portion 130 may be formed on the inner surface of the outer plate portion 21, and the other part may be formed on the outer surface of the inner plate portion 11.

That is, if the inner plate 11 and the outer plate 21 are formed to be locked with each other, the elastic support of the vibration applied to the juice extracting tube 400 can be improved.

Next, a third modification of the juice extracting tube according to the present invention will be described. Fig. 23 is a perspective view of an inner module according to a third modification, and fig. 24 is an operation state view of a juice extracting barrel according to the third modification.

Referring to fig. 23, in the inner module 10 according to the third modification, the formation position of the first rib 13 formed on the inner side surface of the inner panel portion 11 is changed, and the inclined surface 18 is further increased.

The first rib 13 according to the third modification is formed at a position abutting on the width direction end of the slit 12 or adjacent to the slit 12. The first rib 13 is shown abutting the widthwise end of the slit 12.

When the first rib 13 is formed adjacent to the slit 12, the slag can be less likely to be caught in a gap described later than when the first rib 13 is formed in the central portion of the inner panel 11.

That is, when the first rib 13 is formed adjacent to the slit 12, the pressing force applied to the gap in the process of passing the object to be juiced over the first rib 13 is reduced, and therefore, the dirt can be reduced from being caught in the gap.

Further, of the longitudinal edges of the slit 12 formed on the inner surface of the inner plate portion 11, the inclined surface 18 for preventing the dross from being caught in the gap may be formed on the longitudinal edge located upstream with respect to the rotation direction of the screw 300.

If this is expressed differently centering on the slit 12, the first rib 13 is formed on the upstream side edge of the slit 12 and the inclined surface 18 is formed on the downstream side edge of the slit 12.

The ribs 22 of the outside block 20 are inserted into the slits 12, and a gap a is formed between the slits 12 and the ribs 22 to discharge juice of the crushed juicing object. At this time, dregs to be juiced may be caught in the gap a. However, the first rib 13 and the inclined surface 18 prevent dregs to be juiced from being caught in the gap a.

This is explained in detail with reference to fig. 24. When the screw 300 rotates inside the inner block 10, the object to be juiced moves downward in a space where the distance between the screw flight 310 and the inner plate 11 gradually decreases.

At this time, when the amount of the dregs of the juicing object crushed between the screw 300 and the inner module 10 is a small amount which is not enough to pass over the first rib 13, the dregs move to the lower side of the inner module 10 along the first rib 13.

At this time, when the amount of dross increases to an amount sufficient to pass over the first rib 13, the dross passes over the first rib 13 and moves toward the adjacent first rib 13 by the rotational force of the screw 300.

Also, due to the height of the first ribs 13, the dross moves toward the adjacent first ribs 13 across the gap a between the slit 12 and the rib 22. When the dross passes over the first rib 13, the dross moves to the adjacent first rib 13 along the inclined surface 18 formed on the edge of the slit 12 opposite to the first rib 13, and thus the dross can be prevented from being caught in the gap a between the slit 12 and the rib 22.

Then, the dross colliding against the adjacent first rib 13 moves to the lower side of the inner module 10 along the adjacent first rib 13.

Also, in the process that the object of juicing passes over the first rib 13, the pressing force applied to the gap a formed between the slit 12 and the protrusion 22 is reduced, and thus the inclusion of dregs in the gap can be minimized.

Next, a fourth modification of the juice extracting tube according to the present invention will be described. Fig. 25 is a perspective view of an outside module according to a fourth modification, and fig. 26 is a bottom perspective view of a coupled state of a juice extracting cartridge according to the fourth modification.

Referring to fig. 25 and 26, in a juice extracting module 400 according to a fourth modification, the outer plate portion 21 of the outer module 20 is formed as a continuous plate surface whose outer surface is closed. A step portion 28 protruding radially outward is formed on the outer surface 21. At this time, a step difference is illustrated between the stepped portion 28 and the outer flange 27.

Also, the juice discharge hole 23 may be formed on the floor surface protruding radially outward from the step portion 28.

With this structure, juice discharged from the upper portion of the slit a can be discharged to the outer lower portion of the outer module 20 through the juice discharge hole 140.

In this case, since the outer surface of the outer block 20 is formed of a closed continuous surface, juice can be prevented from being splashed onto the inner surface of the cartridge case 200.

Next, a fifth modification of the juice extracting tube according to the present invention will be described. Fig. 27 is a perspective view of an outside module according to a fifth modification, and fig. 28 is a bottom perspective view of fig. 27.

Referring to fig. 27 and 28, in a juice extracting module 400 according to a fifth modification, the outer plate portion 21 is extended to the lower side of the outer flange 27 of the outer module 20, so that a lower protrusion 21a is further formed, and the inner plate portion 11 of the inner module 10 is formed to a length corresponding to the lower protrusion 21 a.

The juice extracting module 400 according to the fifth modification can extract juice not only to the outside of the outer module 20 through the juice extracting holes 23 of the outer module 20 but also to the lower side along the longitudinal slit a formed between the inner module 10 and the outer module 20, so that the juice extracting efficiency can be improved.

Next, a juice extractor according to another embodiment of the present invention is explained. Fig. 29 is a perspective view of a juice extractor according to another embodiment of the present invention.

Referring to fig. 29, in the juice extractor according to another embodiment of the present invention, the coupling position of the cartridge housing is changed to be provided on the side of the main body, compared to the above-described one embodiment.

For this purpose, a decelerator accommodating portion 4 is further provided to extend laterally from the central portion of the main body portion 1 to one side. A speed reducer is disposed inside the speed reducer housing portion 4.

At this time, the decelerator accommodating part 4 may be formed in a shape corresponding to the lower surface of the cartridge case 200 to enable the cartridge case 200 to be mounted.

Also, the cylinder case 200 is installed in the reducer housing part 1 of the main body part 1 so that power of a driving shaft (not shown) receiving power of a driving motor (not shown) can be transmitted to the screw 300.

Also, the upper support part 2 of the main body part 1 may be formed in a shape corresponding to the outer circumferential surface of the cartridge case 200 to support the side part of the cartridge case 200.

In the present embodiment, the reducer case 4 is described as being formed on the lower side of the cartridge case 200, but may be formed on the upper side of the cartridge case 200 as needed.

Other structures in this embodiment are the same as those in the above-described embodiment, and therefore detailed descriptions thereof are omitted.

As described above, according to the embodiments of the present invention, by configuring the juice extracting tube composed of two modules, dregs cannot be caught in very small fine holes as compared with the conventional mesh tube, and thus it is possible to provide a juice extracting module which is remarkably easy and convenient to clean.

In the case of two juice squeezing modules, the juice is discharged through the slit formed by the rib and the slit formed by the protruding plate surface and the partitioned space, so that the juice squeezing module can be prevented from being deformed under a strong squeezing force.

In addition, the gap and the partitioned space can maintain a constant size even under a strong pressing force by a plurality of structures in which the two modules are coupled to each other, and thus the juicing efficiency can be improved.

The embodiments of the present invention have been described in detail, but the present invention is not limited to the above embodiments, and various modifications and improvements made by those skilled in the art using the basic concept of the present invention defined in the claims are within the scope of the present invention.
