Description

Technology Field

[0001] The present invention relates to a separating screw and a juicer using the separating screw, and more specifically, to a separating screw configured to be detachably composed of two modules and a juicer using the same. Background Technology

[0002] Recently, as interest in health has increased in households, the frequency of using juicers that allow individuals to directly make juice from vegetables, grains, or fruits and consume it is increasing.

[0003] The general operating method of such a juicer is a method of pressing and squeezing the object to be juiced using the principle of, for example, grinding soybeans with a millstone and extracting the juice, as disclosed in Korean Registered Patent No. 793852.

[0004] To this end, the juicer is equipped with: a drive unit that provides rotational force; a juice drum having a drive shaft that receives rotational force from the drive unit; a screw connected to the drive shaft inside the juice drum and compressing and crushing the object to be juiced by means of a screw spiral formed on a part thereof; and a mesh drum for separating the juice produced by the screw. The drive unit that provides rotational force to the juicer includes a motor and a reduction gear. The motor is connected to the drive shaft to transmit rotational force to the screw. To this end, the drive shaft passes through the lower part of the juice drum and is connected to the screw.

[0005] Generally, mesh drums have a mesh structure. However, mesh drums have the problem of low extraction efficiency because they are prone to clogging by the material being juiced. Additionally, since the mesh is formed very tightly, it is difficult to clean the material stuck in the mesh. Furthermore, while various filter structures can be envisioned, they are difficult to apply to screw-type juicers that use a compression method, such as those that perform only simple filtration functions. The problem to be solved

[0006] The present invention has been devised to solve the problems described above, and aims to provide a separable screw and a juicer using the same, wherein the screw is configured to be detachably connected to two modules so that the screw performs the function of a conventional mesh drum and is easy to clean. means of solving the problem

[65535] A juicing drum according to the present invention is a juicing drum having a separation screw disposed inside that rotates by receiving rotational force from a drive shaft, a juice outlet for discharging juice, and a pulp outlet for discharging pulp. At least one rib ridge is formed along the circumferential direction on the inner surface, and a drum hole is provided in the lower center that is formed in a shape corresponding to the shape of the drive shaft. The separation screw comprises a first body having a plurality of slits formed therein and a first module having a screw hole formed therein for receiving rotational force from the drive shaft, a second body having a plurality of ribs formed therein that are inserted into the slits, and a second module having an annular flange formed on its upper side. A gap is formed in the longitudinal direction to allow juice to flow into the interior when the ribs are inserted into the slits. A screw spiral projection is formed on the outer surface of at least one of the first body and the ribs, and a lower ring is further formed on the lower inner surface of the second module. In another aspect of the juicing drum according to the present invention, the lower ring protrudes from the inner surface of the second module. The lower ring of the juicing drum according to another present invention is formed by protruding from the inner circumferential surface of the second module by forming an inclined surface. The lower ring of the juicing drum according to another present invention is formed by being bent and protruding from the inner circumferential surface of the second module. A through hole is formed in the inner center of the second module of the juicing drum according to another present invention, which is connected to the flange and through which the screw shaft of the screw passes. The through hole of the juicing drum according to another present invention is formed in a shape corresponding to the shape of the screw shaft of the screw. The juicing drum according to another present invention is a juicing drum in which a separation handle is further formed by protruding radially inward from the inner circumferential surface of the second module. The separation handle of the juicing drum according to another present invention is formed in the shape of a flat plate. The separation handle of the juicing drum according to another present invention is formed such that its width narrows as it moves radially inward.In addition, the separation handles of the juicing drum according to the present invention are formed in plurality on the inner circumference of the second module. Effects of the invention

[0051] According to an embodiment of the present invention, the conventional mesh drum is eliminated, making the configuration simple and reducing manufacturing costs.

[0052] In addition, it is easier to clean than conventional mesh drums and can improve juicing efficiency.

[0053] In addition, the problem of mesh holes clogging in conventional mesh drums is fundamentally resolved, eliminating the need for the brush that conventional vertical juicers had to have, and also eliminating the need for various parts to drive the brush. Brief explanation of the drawing

[0058] FIGS. 1 and 2 are exploded perspective views of a juicer according to an embodiment of the present invention, FIGS. 3 and 4 are exploded perspective views of a separation screw according to an embodiment of the present invention shown in FIGS. 1 and 2, FIG. 5 is an assembled perspective view of the separation screw of FIG. 2, FIG. 6 is a cross-sectional view cut along I-I' in FIG. 5, FIG. 7 is a cross-sectional view cut along II-II' in FIG. 5, FIG. 8 is a cross-sectional view cut along III-III' in FIG. 6, FIG. 9 is a perspective view of a juice drum shown in FIGS. 1 and 2, and FIG. 10 is a cross-sectional view of a juice drum to which the separation screw of the present invention is applied.

[0059] As illustrated in FIGS. 1 and 2, a juicer according to one embodiment of the present invention may include a hopper (100), a juice drum (200), and a separating screw (300).

[0060] The hopper (100) is detachably coupled to the upper part of the juicing drum (200), so that the juicing target (e.g., vegetables, grains, fruits, etc.) is fed through the hopper (100) and then guided to the juicing drum (200).

[0061] The juicing drum (200) is formed in a cylindrical shape with an open top, and a separation screw (300) may be disposed inside. A juice outlet (220) capable of discharging juice and a residue outlet (230) capable of discharging residue may be formed on one side of the lower part of the juicing drum (200). When the separation screw (300) rotates, the juicing target is separated into residue and juice by the interaction between the juicing drum (200) and the separation screw (300), and the residue remains at the radially outer lower end of the separation screw (300), while the juice moves radially inward of the separation screw (300) to the lower end. Afterward, the residue is discharged through the residue outlet (230), and the juice is discharged through the juice outlet (220) via a path different from the path through which the residue is discharged.

[0062] A drum hole (240) is formed in the lower center of the juicing drum (200). A drive shaft (not shown) is inserted through the drum hole (240) and can transmit power by combining with a separation screw (300) located inside the juicing drum. The inner surface of the drum hole (240) may have a shape corresponding to the shape of the drive shaft so that the drive shaft can be inserted.

[0063] The separation screw (300) receives power through a drive shaft inside the juicing drum (200) and rotates, and through interaction with the juicing drum (200), separates the juicing target introduced through the hopper (100) into residue and juice, and the separated juice moves into the inside of the separation screw (300) and is discharged through the juice outlet (220). The separation screw (300) according to the present invention is configured to be separated and combined into a first module (10) and a second module (20), and the separation screw (300) according to one embodiment of the present invention will be described in detail below with reference to FIGS. 3 to 8.

[0064] A separation screw (300) according to one embodiment of the present invention may be configured to include two cylindrical first modules (10) and second modules (20).

[0065] The first module (10) is formed by including a first main body (14) which is generally open at the bottom and has a hollow formed inside, and a plurality of slits (15) formed longitudinally along the circumference of the first main body (14). Although the drawing shows a rod-shaped slit (15) that is long in the longitudinal direction, the slit (15) is not limited to a rod-shaped hole or an egg-shaped hole as long as it is a hole that appears to intersect with the screw spiral projection (13) described later. Additionally, in the drawing, the slits (15) are formed at equal intervals along the circumference of the first main body (14), but are not necessarily limited to this.

[0066] On the outer surface of the first main body (14), a screw spiral projection (13) (hereinafter referred to as a ‘screw spiral’ for convenience) may be formed diagonally with respect to the longitudinal direction (or vertical direction). The screw spiral (30) crushes and / or extracts juice from the object to be extracted through interaction with the juice drum (200), and may be formed as at least one spiral.

[0067] As shown in FIG. 4, a screw shaft (11) that is coupled to a drive shaft may be formed extending downward in the center of the interior of the first main body (14). Additionally, the screw shaft (11) may be formed protruding from the upper surface of the first main body (14) and inserted rotatably into a receiving hole formed on the bottom surface of the hopper (100). A screw hole (12) that receives the rotational force of the drive shaft is drilled in the lower part of the screw shaft (11).

[0068] The second module (20) may be formed with a second main body (22) having a cylindrical shape with a generally closed top and a plurality of ribs (21) protruding from the outer surface of the second main body (22) in a shape corresponding to the slit (15) of the first module (10). The ribs (21) shown in FIGS. 3 and 4 are formed integrally with the second main body (22) in a shape protruding from the second main body (22), but they may also be formed so as to be detachably fitted into the second main body (22). Additionally, it is preferable that the ribs (21) be formed such that the width of the ribs (21) increases from the top to the bottom. Correspondingly, it is also preferable that the aforementioned slit (15) be formed such that the width of the slit (15) increases from the top to the bottom. As the rib (21) and slit (15) are formed to widen from the top to the bottom in this way, when the first module (10) and the second module (20) are moved up and down and the two modules (10, 20) are combined so that the rib (21) is inserted into the slit (15), a sliding connection between the slit (15) and the rib (21) can be stably performed.

[0069] A screw spiral projection (29) (hereinafter referred to as a ‘screw spiral’ for convenience) may also be formed on the outer surface of the second module (20), just as it is on the first module (10). In the case of the second module (20), the screw spiral projection (29) may be formed on the outer surface of the rib (21). At this time, depending on the shape of the screw spiral and the position of the rib (21), the screw spiral projection (29) may not be formed on the outer surface of some ribs (21).

[0070] In addition, when the first module (10) and the second module (20) are combined, the screw spirals (13, 29) formed on the first module (10) and the second module (20) can be formed continuously as shown in FIG. 5. Although some sections may be slightly interrupted, generally continuous screw spirals (13, 29) are formed. To this end, the outer diameter of the first main body (14) forming the slit (15) and the outer diameter of the rib (21) are the same, and the protrusion heights of the screw spiral protrusions (13, 29) may also be the same.

[0071] As illustrated in FIG. 3, a through hole (30) into which a screw shaft (11) is inserted may be formed on the upper surface (27) of the second module (20). To fix the coupling position of the first module (10) and the second module (20) and to prevent relative rotation between the first module (10) and the second module (20), the through hole (30) may be a square hole, and the screw shaft (11) may be formed as a square shaft with a shape corresponding to the through hole (30). FIG. 3 and FIG. 4 illustrate that the through hole (30) and the screw shaft (11) are square, but the shape of the through hole (30) is not limited to the example. In this specification, the first module (10) and the second module (20) may be fixed at four different positions by the screw shaft (11), which is a square-shaped shaft, and the through hole (30), which is a square-shaped hole.

[0072] At this time, the connection position of the first module (10) and the second module (20) may be constant so that the screw spiral projection (13) formed on the first module (10) and the screw spiral projection (29) formed on the second module (20) coincide. That is, assuming that the angle formed along the circumferential direction between the reference point of the first module (10) and the reference point of the second module (20) at the position where the first module (10) and the second module (20) are completely connected is 0 degrees, the first module (10) and the second module (20) can be completely connected by the square axis and the square hole only when the reference point of the first module (10) and the reference point of the second module (20) have an angle set along the circumferential direction (e.g., 90 degrees, 180 degrees, 270 degrees). At this time, the screw spiral projection (13) formed on the first module (10) and the screw spiral projection (29) formed on the second module (20) may coincide (i.e., form a continuous screw spiral). In order to maintain a constant connection position between the first module (10) and the second module (20), a space with a relatively narrow gap and a space with a relatively wide gap between the plurality of ribs (21) may be periodically formed at each angle set along the circumferential direction.

[0073] Additionally, screw spiral protrusions (29) may not be formed on the outer surface of the rib (21) of the second module (20). In this case, by forming the width of the rib (21) narrowly, the same or similar juicing efficiency can be achieved compared to the case where screw spiral protrusions (29) are formed on the outer surface of the rib (21).

[0074] A seating groove (25) may be formed on the lower side of the second module (20) so that a separation screw (300) can be seated on the juicing drum (200). On the lower surface of the juicing drum (200), a seating projection (not shown) corresponding to the seating groove (25) may be formed protruding upward. A packing may be placed in the seating groove (25), and by combining the seating groove (25) to surround the seating projection, the residue separated during the juicing process can be prevented from entering the inside of the screw (300).

[0075] Additionally, as shown in FIGS. 3 and 4, a first step (16) may be formed at the bottom of the first body (14) of the first module (10), and a second step (23) may be formed on the lower side of the second body (22) in correspondence. By combining the second step (23) of the second module (20) and the first step (16) of the first module (10), the pressure transmitted to the screw (300) is withstood, and debris is prevented from entering the inside of the screw (300).

[0076] Meanwhile, a magnet receiving portion (26) may be formed on the upper surface (27) of the second module (20). In order to prevent the second module (20) and the first module (10) from being easily separated when the second module (20) is coupled to the first module (10), a magnet is placed in the magnet receiving portion (26) and a magnet or magnetic body of opposite polarity is placed on the inner side of the first module (10), thereby allowing the second module (20) to be stably coupled to the first module (10) by magnetic force.

[0077] When the first module (10) and the second module (20) formed as described above are combined, the inner diameter of the first body (14) of the first module (10) is larger than the outer diameter of the second body (22) of the second module (20), so the first module (10) wraps around and combines to accommodate the second module (20). When the rib (21) of the second module (20) is inserted into the slit (15) of the first module (10) and combined, the part of the first body (14) where the slit (15) is not formed and the part of the second body (22) where the rib (21) is not formed are combined in a radially overlapping manner.

[0078] At this time, as the rib (21) of the second module (20) is inserted into the slit (15) of the first module (10), a predetermined gap (a) is formed between the slit (15) and the rib (21). Juice flows into the inside of the separation screw (300) through the gap (a) and is discharged, and the residue from which the juice has been separated can be collected at the bottom between the separation screw (300) and the juice extraction drum (200) and discharged to the outside. The gap (a) can be formed along the entire length of the separation screw (300), but preferably, it can be formed at the lower end of the separation screw (300) for a predetermined length.

[0079] At this time, the gap (a) can be formed to become larger as it extends radially inward, as shown in FIG. 6. For example, if the width of the slit (15) is formed to become wider as it extends radially inward, as shown in FIG. 6, the gap (a) formed between the slit (15) and the rib (21) can be formed to become larger as it extends radially inward when the rib (21) is inserted into the slit (15). By forming the gap (a) to gradually become larger as it extends radially inward in this way, problems such as the gap (a) becoming clogged by residue or obstructing the flow of juice during the juicing process can be prevented. In this embodiment, the gap (a) is formed to become larger as it extends radially inward through the shape of the slit (15), but the shape of the gap (a) described above can be formed in various ways through the shape of the rib (21) or through a combination of the shapes of the rib (21) and the slit (15).

[0080] Additionally, as shown in the enlarged view of FIG. 5, the gap (a) can be formed to become smaller as it extends downward along the longitudinal direction. In this way, the shape change of the longitudinal gap (a) can be formed in various ways through a combination of the shapes of the slit (15) or the rib (21), in the same manner as the shape of the radial gap (a). Furthermore, the gap (a) can be formed to gradually narrow from the top to the bottom, or it can be formed in stages with the upper gap (a) being wide and the lower gap (a) being narrow, centered around a predetermined point.

[0081] Since greater pressure is applied to the lower side of the separation screw (300), it is desirable for the gap (a) on the lower side to be formed narrowly. For example, in the case of a hard juicing target such as a carrot, the juice can be discharged mostly through the gap (a) formed on the lower side during the pressing process. In the case of a soft juicing target such as a tomato, the juice can be discharged not only through the gap (a) formed on the lower side during the pressing process, but also as the juice accumulated in the gap (a) formed on the lower side rises to the wide gap (a) on the upper side. In this way, by not making the size of the gap (a) uniform in the longitudinal direction, the juicing efficiency can be improved for both hard juicing targets such as carrots and soft juicing targets such as tomatoes.

[0082] Additionally, when the first module (10) and the second module (20) are combined, a gap can be formed between the outer surface of the second main body (22) and the inner surface of the first main body (14), as shown in FIGS. 6 to 8, to form a gap space. (For reference, the juice extraction drum (200) is also shown in FIGS. 6 to 8 with a dotted line for better understanding.) Juice that has flowed into the gap space through the gap (a) can move to the lower part between the first module (10) and the second module (20). At this time, a juice discharge hole (28) can be formed on the lower side of the second main body (22). Juice collected at the lower part of the gap space between the first module (10) and the second module (20) can flow into the inside of the separation screw (300) through the juice discharge hole (28).

[0083] At this time, the gap can become wider as it goes toward the lower side of the separation screw (300), as shown in FIG. 8. The gap can secure a space where juice can flow between the first module (10) and the second module (20) through the gap (a).

[0084] Hereinafter, a juicing drum (200) that accommodates the aforementioned separation screw (300) inside and interacts with the separation screw (300) when it rotates to separate the juicing target into juice and residue will be described in more detail with reference to FIGS. 9 and 10.

[0085] A plurality of first rib jaws (260) and second rib jaws (250) may be formed at regular intervals along the circumferential direction on the inner surface of the juicing drum (200). The first rib jaws (260) and second rib jaws (250) may be formed in the longitudinal direction or inclined at an acute angle to the longitudinal direction. As the separation screw (300) rotates, the material may be compressed or crushed by the interaction between the screw spiral (13, 29) and the first rib jaws (260) and the second rib jaws (250). The first rib jaws (260) may additionally perform the function of guiding the juicing target to the lower part of the juicing drum (200). In addition, the first rib jaws (260) may perform the function of adjusting the position of the separation screw (300) and adjusting the juicing space in addition to the function of compressing and crushing the material.

[0086] The first rib (260) may be formed along the longitudinal direction of the juicing drum (200), and the second rib (250) may be formed only on a portion of the longitudinal direction of the juicing drum (200) (more specifically, the lower part of the juicing drum (200)). That is, the length of the first rib (260) may be formed to be longer than the length of the second rib (250).

[0087] If the first rib jaw (260) and the second rib jaw (250) are not present, the object to be squeezed may not go down and may become stagnant, or the compressive force or crushing force may be low or not occur. Additionally, the first rib jaw (260) and the second rib jaw (250) can prevent deformation of the juice drum (200) that may occur due to the compressive force generated during the process of conveying and crushing the material by the spiral of the separation screw (300).

[0088] Generally, the first rib jaw (260) and the second rib jaw (250) serve to allow the material fed into the interior of the juicing drum (200) to be inserted into the narrow part where it comes into contact with the screw (300), thereby allowing the material to go down. The first rib jaw (260) and the second rib jaw (250) can perform the function of crushing and squeezing the material well together with the screw spiral (13, 29) while allowing the material to go down. Therefore, the first rib jaw (260) and the second rib jaw (250) do not need to be formed in the longitudinal direction of the juicing drum (200), and may also be implemented in an inclined shape having a constant slope with respect to the longitudinal direction in order to efficiently transport and compress the material in a form that intersects with the screw spiral (13, 29).

[0089] Additionally, the first rib (260) is formed along the longitudinal direction on the inner surface of the juicing drum (200) and can perform the functions of guiding and compressing the material, as well as reinforcing the juicing drum (200) to prevent deformation caused by the compressing force generated during the process of conveying and compressing the material by the screw spiral (13, 29), and adjusting the position of the screw (300) within the juicing drum (200) and adjusting the juicing space.

[0090] Additionally, the protrusion height of the first rib jaw (260) may be configured to have the same height from the top to the bottom, but it may gradually decrease from the top to the bottom, or at least one protruding step portion (260a) may be formed in the middle portion along the length of the first rib jaw (260). Based on the step portion (260a), the protrusion height of the upper part of the first rib jaw (260) may be lower than the protrusion height of the lower part of the first rib jaw (260).

[0091] A third rib (270) may be additionally formed on the inner surface of the juicing drum (200). The third rib (270) may be formed between the first rib (260) or between the second rib (250).

[0092] For example, a plurality of first ribs (260) may be formed along the circumferential direction on the inner surface of the juicing drum (200), a plurality of second ribs (250) may be formed between the first ribs (260), and a plurality of third ribs (270) may be formed between the first ribs (260) and the second ribs (250) and / or between the second ribs (250). Preferably, the vertical length of the third ribs (270) may be shorter than that of the first ribs (260) and longer than that of the second ribs (250).

[0093] Below, the first rib jaw (260), the second rib jaw (250), and the third rib jaw (270) will be described in more detail.

[0094] The first rib (260) performs the function of conveying the material fed into the interior of the juicing drum (200) downward and crushing the juicing target in the first step. To this end, the first rib (260) may be formed vertically in the up-and-down direction on the inner surface of the juicing drum (200). The protruding height (h) of the first rib (260) may be formed to have the same height (h) from the top to the bottom of the juicing drum (200). Preferably, the protruding height (h) of the first rib (260) may be formed in a shape that gradually decreases from the top to the bottom of the juicing drum (200).

[0095] The number and arrangement of the first rib tuck (260) can be varied as needed, taking into account design conditions and the efficiency of juicing.

[0096] In an embodiment of the present invention, the formation direction of the first rib jaw (260) is described as being formed perpendicularly to the up-and-down direction of the juicing drum (200), but the scope of the present invention is not limited thereto. That is, the first rib jaw (260) may be formed to intersect with the screw spiral (13, 29) of the separation screw (300), and thus may be formed to have a certain inclination so that the object to be juiced is conveyed downward and first crushed by the interaction between the separation screw (300) and the first rib jaw (260) of the juicing drum (200).

[0097] The first rib (260) is formed to slope downward from the top to the bottom of the juicing drum (200), and a stepped portion (260a) can be formed in the middle portion by protruding toward the separation screw (300). The position, number, or protruding height of the stepped portion (260a) can be varied according to the shape of the separation screw (300) and the design conditions of the screw spiral (13, 29).

[0098] The second rib (250) is received inside the juice drum (200) and is conveyed downward by the rotation of the separating screw (300) that rotates, and performs the function of finely and uniformly crushing the juiced object in cooperation with the separating screw (300) in a second step.

[0099] To this end, the second rib (250) may be formed on the lower inner surface of the juicing drum (200). The second rib (250) may be formed with a shorter vertical length compared to the first rib (260). That is, the first rib (260) may be formed from the upper to the entire lower portion of the juicing drum (200), while the second rib (250) may be formed only up to a set height from the lower portion of the juicing drum (200).

[0100] If the second rib jaw (250) is formed in the middle part inside the juicing drum (200), the material in the middle part of the juicing drum (200) is finely crushed by the second rib jaw (250) and the separation screw (300), and the particle size of the juicing target is rapidly reduced, so that the juicing target cannot be caught on the second rib jaw (250) at the bottom of the juicing drum (200) and rotates together with the screw spiral (13, 29) of the separation screw (300). Consequently, the problem occurs where the juicing target cannot be smoothly transported downward along the screw spiral (13, 29) of the separation screw (300) and becomes stagnant inside the juicing drum (200). When the juicing target becomes stagnant inside the juicing drum (200), the stagnation of the juicing target is further exacerbated by additional juicing targets being fed in, and the inconvenience of having to forcibly press the juicing target using a separate tool to feed it in occurs.

[0101] In order to prevent such problems from occurring, the second rib jaw (250) according to an embodiment of the present invention is formed at the bottom of the juicing drum (200), so that the particle size of the object to be juiced does not change abruptly but changes gradually, and as a result, the object to be juiced is smoothly conveyed downward by the screw spiral (13, 29) and the first rib jaw (260), and the object to be juiced can be further finely crushed by the second rib jaw (250) at the bottom of the juicing drum (200).

[0102] And as the second rib jaw (250) is formed at the bottom of the extraction drum (200), the extraction target is smoothly transported from the top to the bottom of the extraction drum (200) by the separation screw (300) and the first rib jaw (260), and the pressure caused by the extraction target residue of the extraction drum (200) and the separation screw (300) gradually increases. Due to this pressure, the juice extracted from the extraction target flows into the interior of the separation screw (300) through the gap (a) formed between the slit (15) of the first module (10) of the separation screw (300) and the rib (21) of the second module (20), and can be smoothly discharged.

[0103] A third rib (270) that is shorter than the first rib (260) and longer than the second rib (250) may be formed between the first rib (260) or between the second rib (250).

[0104] The third rib jaw (270) performs a function that assists the role of the first rib jaw (260). That is, if the installation spacing of the first rib jaw (260) is too far, the object to be juiced may not be able to descend smoothly to the bottom of the juice drum (200). Therefore, by forming a third rib jaw (270) between the first rib jaws (260) that is shorter than the first rib jaw (260) and longer than the second rib jaw (250), the object to be juiced can move smoothly to the bottom of the juice drum (200).

[0105] Referring to FIG. 10, the relationship between the juicing drum (200) and the separating screw (300) will be explained.

[0106] As shown in FIG. 10, the upper inner surface of the juicing drum (200) is formed to be inclined at a certain angle (A) with respect to a vertical line. That is, the diameter of the inner surface of the juicing drum (200) is formed to become smaller from top to bottom.

[0107] The protruding height of the first rib jaw (260) formed on the inner surface of the juice extraction drum (200) is formed to gradually decrease from the top to the bottom, thereby being formed to be inclined evenly in the vertical direction. At this time, the outer surface of the first rib jaw (260) is formed to be inclined at a certain angle (B) relative to a vertical line. That is, the first rib jaw (260) is formed to be inclined toward the center of the juice extraction drum (200) as it goes from the top to the bottom. At this time, as shown in the enlarged view on the right side of FIG. 10, the outer surface of the first rib jaw (260) can be formed parallel to or nearly adjacent to the straight line formed by the screw spiral (13, 29) formed in the vertical direction of the separation screw. That is, the first rib jaw (260) can be formed to be in contact with or nearly in contact with the screw spiral (13, 29) of the separation screw (300), and to be in contact with or parallel to the shape of the outer side of the separation screw (300).

[0108] And the outer surface of the separation screw (300) accommodated in the juicing drum (200) is formed to be inclined at a certain angle (C) with respect to a vertical line. That is, the diameter of the outer surface of the separation screw (300) can be formed to become smaller from the top to the bottom.

[0109] At this time, it is preferable that the angle (B) formed by the outer surface of the first rib jaw (260) with the vertical line and the angle (C) formed by the outer surface of the separation screw (300) with the vertical line are formed identically as described above. That is, the outer surface of the first rib jaw (260) and the outer surface of the separation screw (300) are formed to coincide or nearly coincide in parallel.

[0110] At this time, it is preferable that the inner surface of the juicing drum (200) be formed such that the distance from the separation screw (300) becomes closer as it goes from the top to the middle section, as shown in the enlarged view on the right side of FIG. 10. Additionally, the distance from the separation screw (300) may be formed such that it becomes farther as it goes from a predetermined position in the middle section of the juicing drum (200) toward the bottom. This is because the object to be juiced is crushed and its size becomes progressively smaller as it goes from the top to the middle section of the juicing drum (200). Therefore, the distance from the separation screw (300) is formed to become closer up to a predetermined position in the middle section, and then the distance from the separation screw (300) becomes farther as it goes toward the bottom to secure a space for the movement of the residue. At this time, as shown in another enlarged view on the right side, the inner surface of the juicing drum (200) may be formed such that it maintains a constant distance from the separation screw (300) as it goes from the middle section toward the bottom.

[0111] As described above, according to an embodiment of the present invention, the conventional mesh drum is eliminated, thereby simplifying the configuration and reducing manufacturing costs. Furthermore, by eliminating the conventional mesh drum, cleaning is simplified and juicing efficiency can be improved.

[0112] Hereinafter, various modified examples of the separation screw described with reference to FIGS. 11 to 23 will be described.

[0113] FIGS. 11 and 12 are exploded perspective views according to a first modified example of a separating screw, FIGS. 13 and 14 are exploded perspective views according to a second modified example of a separating screw, FIG. 15 illustrates various embodiments of the support member of FIG. 10, FIG. 16 is an exploded perspective view according to a third modified example of a separating screw, FIG. 17 is an assembled perspective view of FIG. 16, FIG. 18 is a cross-sectional view cut along IV-IV' of FIG. 17, FIG. 19 is an exploded perspective view according to a fourth modified example of a separating screw, FIG. 20 is an assembled perspective view of FIG. 19, FIG. 21 is a cutaway perspective view of a juicing drum to which the separating screw of FIG. 20 is applied, and FIG. 22 and 23 are exploded perspective views according to a fifth modified example of a separating screw.

[0114] According to the modified example illustrated in FIGS. 11 and 12, a protruding first gap-maintaining step (50) may be formed on the upper side of the slit (15). Additionally, a protruding second gap-maintaining step (55) may be formed on the lower side of the rib (21). During the juicing process, the size of the gap (a) between the slit (15) and the rib (21) may change while the separation screw (300) rotates. Due to the first gap-maintaining step (50) and the second gap-maintaining step (55), the size of the gap (a) formed between the slit (15) and the rib (21) may be maintained at a constant level even during the juicing process.

[0115] According to the modified example illustrated in FIGS. 13 and 14, in order to fix the coupling position of the first module (10) and the second module (20), a key projection (40) may be formed on the bottom surface of the upper surface of the first module (10), and a key groove (45) into which the key projection (40) is inserted may be formed on the upper surface of the second module (20). By fitting the key projection (40) into the key groove (45), the coupling position, rotation, and tilting of the first module (10) and the second module (20) can be restricted.

[0116] Additionally, as shown in FIGS. 13 and 14, a support member (31) protruding from the outer surface may be formed on the outer surface of the second main body (22). The protrusion height of the support member (31) is smaller than the protrusion height of the rib (21), and the support member (31) ensures that the inner surface of the first main body (14) and the outer surface of the second main body (22) are in close contact with each other when the first module (10) and the second module (20) are combined, thereby supporting strong radial and circumferential pressures generated when compressing residue and juiced objects, and preventing noise generated when the separation screw (300) rotates.

[0117] FIG. 15 illustrates various embodiments of such a support member (31). First, as shown in (a), the support member (31) may be formed to protrude from the outer surface of the second body (22) and to contact the inner surface of the first body (14), or conversely, as shown in (b), it may be formed to protrude from the inner surface of the first body (14). Additionally, as shown in (c) and (d), it may be formed with a first support member (31a) protruding from the inner surface of the first body (14) and a second support member (31b) protruding from the outer surface of the second body (22), so that one side of the first support member (31a) and the second support member (31b) come into contact with each other. That is, the first support member (31a) is formed to contact the outer surface of the second main body (22) and the second support member (31b) is formed to contact the inner surface of the first main body (14), and at the same time, the sides of the first support member (31a) and the second support member (31b) may be formed to contact each other as shown in (c) or (d). As the sides of the first support member (31a) and the second support member (31b) are formed to contact each other in this way, strong pressure in the circumferential direction can be supported more stably. In addition, as shown in (e), an insertion groove (32) may be formed on the inner surface of the first main body (14) so ​​that the end of the support member (31) protruding from the outer surface of the second main body (22) is inserted, and they may be joined in a fitted manner.

[0118] In this embodiment, a support member (31) is described as being integrally formed protruding from the inner surface of the first body (14) or the outer surface of the second body (22), but it may also be formed as a separate member inserted between the first body (14) and the second body (22). Furthermore, the shape of the support member (31) is not limited to the shape described above, and can be modified in various ways as long as it is formed to be interposed between the inner surface of the first body (14) and the outer surface of the second body to provide mutual support.

[0119] In addition, the contact portion of the support member (31) can be formed with a silicone or elastic material pad to absorb pressure and further reduce noise caused by vibration.

[0120] According to the modified example illustrated in FIGS. 16 to 18, a first inclined surface (14-1) may be formed toward the slit (15) at the upstream longitudinal edge portion of the slit (15) of the first module (10) with respect to the rotational direction of the separation screw (300). Additionally, a second inclined surface (21-1) may be formed on the rib (21) of the second module (20) with the downstream edge cut out with respect to the rotational direction of the screw.

[0121] For example, as shown in FIG. 18, when the separation screw (300) rotates counterclockwise and the juicing target moves clockwise, the first inclined surface (14-1) may be formed at the right corner of the slit (15) and the second inclined surface (21-1) may be formed at the left corner of the rib (21).

[0122] When the separation screw (300) rotates, the object to be extracted is crushed and moves between the separation screw (300) and the extraction drum (200). Since the moving speed of the object to be extracted is slower than the rotational speed of the separation screw (300), the object to be extracted moves in a direction relatively opposite to the rotational direction of the separation screw (300). Therefore, the rotational direction of the separation screw (300) and the moving direction of the object to be extracted are opposite.

[0123] In this way, by forming a first inclined surface (14-1) on the corner portion of the slit (15) and forming a second inclined surface (21-1) on the rib (21), it is possible to prevent the object to be squeezed from the gap (a) formed between the slit (15) of the first module (10) and the rib (21) of the second module (20).

[0124] Specifically, when the separation screw (300) rotates counterclockwise, the residue of the juicing target located between the screw (300) and the juicing drum (200) moves relatively clockwise. As the residue moves clockwise, it moves over the rib and the first inclined surface, and is compressed and crushed by the step between the right edge of the rib (21) and the first inclined surface (14-1), thereby preventing the residue from getting stuck in the gap (a) between the right edge of the rib (21) and the first inclined surface (14-1). In addition, the debris is compressed and crushed by the right second inclined surface (21-1) of the rib (21) and the step at the left corner of the slit (15), so that the debris is prevented from getting stuck in the gap (a) between the right second inclined surface (21-1) of the rib (21) and the left corner of the slit (15).

[0125] According to the modified example illustrated in FIGS. 19 to 21, a separation handle (370) may be formed on the inner surface of the second module (20) to easily separate the first module (10) and the second module (20).

[0126] The separation handle (370) is formed to protrude radially inward from the lower portion of the inner circumference of the second module (20). Specifically, the separation handle (370) is formed in the shape of a flat plate in the vertical direction, and its width may be formed to narrow as it extends radially inward from the inner circumference of the second module (20). Additionally, the separation handle (370) may be formed symmetrically.

[0127] If necessary, multiple separation handles (370) may be formed on the inner surface of the second module (20). Preferably, a pair of separation handles (370) may be formed on the inner surface of the second module (20), and the pair of separation handles (370) may be formed facing each other.

[0128] In this way, by forming a separation handle (370) on the inner surface of the second module (20), the user can easily separate the first module (10) and the second module (20). For example, the user can grasp the upper part of the first module (10) with one hand and hook the separation handle (370) with the other hand to separate the first module (10) and the second module (20) in opposite directions. Thus, the user can easily separate the second module (20) from the first module (10) by using the separation handle (370).

[0129] Additionally, an insertion groove (371) is formed concavely in the center of the separation handle (370), and a brush (380) formed of an elastic material can be attached to the insertion groove (371). The brush (380) may include a brush body (381) inserted into the insertion groove (371) and a brush wing (383) extending downward from the brush body (381). When the brush (380) is inserted into and attached to the insertion groove (371) of the separation handle (370), the brush body (381) can be attached to the insertion groove (371) in a press-fit manner while elastically deforming.

[0130] As illustrated in FIG. 21, the brush (380) functions to sweep away the liquid accumulated in the liquid discharge groove (297) so that the liquid temporarily accumulated in the liquid discharge groove (297) can move smoothly to the liquid discharge port (220). To this end, the lower part of the brush blade (383) may be positioned so as to be spaced a certain distance from the bottom surface of the liquid discharge groove (297), or, if necessary, the lower part of the brush blade (383) may be positioned to be in contact with the bottom surface of the liquid discharge groove (297).

[0131] According to the modified example shown in FIGS. 22 to 23, the second body may be formed with an annular flange (24) that fixes the upper side of the rib (21).

[0132] Various embodiments of the separation screw (300) have been described with reference to the drawings. If the first module (10) and the second module (20) are separated and combined, and an external liquid is introduced into the separation screw (300) through the gap (a) between the slit (15) and the rib (21) formed in the first module (10) and inserted into the slit (15), the shape of the separation screw (300) is not limited to the description in the drawings, but can be modified in various ways, including the shape and position of the slit and the rib.

[0133] Hereinafter, the process of discharging juice and residue separated by a separation screw according to an embodiment of the present invention will be described in detail with reference to FIG. 24.

[0134] FIG. 24 is a cutaway perspective view of a juicing drum to which the separation screw of the present invention is applied.

[0135] The left cross-sectional portion of FIG. 24 is illustrated to clearly show the passage through which the filtered residue is discharged after being extracted between the separation screw (300) and the extraction drum (200), and the right cross-sectional portion clearly shows the juice discharge path through which the filtered juice is discharged while being compressed into the internal space of the separation screw (300).

[0136] Additionally, a drum hole (240) is formed in the center of the inner bottom surface of the juicing drum (200). The inner circumference of the drum hole (240) may include a packing (261) for waterproofing, and depending on the design requirements, a waterproof cylinder (280) may be included that protrudes into the inner central space of the separation screw (300). Around the drum hole (240), a guide projection (282) is formed so that the lower ring (390) of the separation screw (300) can be seated. The guide projection (282) is formed at a certain height from the bottom surface of the juicing drum (200) so as to be inserted into the inner circumference of the lower ring (390) of the separation screw (300), and a guide groove (291) may be formed on the upper surface of the guide projection (282). By doing so, the juicing drum is fixedly supported, and debris is prevented from entering the drive shaft.

[0137] A juice discharge groove (297) is formed on the bottom surface of the juice extraction drum (200) radially outward from the drum hole (240), and the juice discharge groove (297) is connected to the juice discharge port (220). Also, a residue discharge groove (298) is formed radially outward from the juice discharge groove (297), and the residue discharge groove (298) is connected to the residue discharge port (230).

[0138] The juice extracted by the interaction between the separation screw (300) and the juice extraction drum (200) moves between the first module (10) and the second module (20) through the gap (a) formed between the slit (15) of the first module (10) and the rib (21) of the second module (20), and moves downward through the gap between the inner surface of the first body (14) of the first module (10) and the outer surface of the second body (22) of the second module (20). Afterwards, it moves into the inside of the separation screw (300) through the juice discharge hole (28) formed in the second body (22) of the second module (20). The juice moved into the inside of the separation screw (300) through the juice discharge hole (28) flows into the juice discharge groove (297) formed along the circumferential direction in the center of the bottom surface of the juice extraction drum. The juice collected in the juice discharge groove (297) can be discharged through the juice discharge port (220).

[0139] Meanwhile, the residue other than the juice extracted by the interaction between the separation screw (300) and the extraction drum (200) moves downward along the space between the outer surface of the separation screw (300) and the inner surface of the extraction drum (200), flows along the residue discharge groove (289) formed on the bottom surface of the extraction drum (200), and is discharged to the outside through the residue discharge port (230).

[0140] Although embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims also fall within the scope of the present invention. Industrial applicability

[0141] According to an embodiment of the present invention, the conventional mesh drum is eliminated, making the configuration simple and reducing manufacturing costs.

[0142] In addition, it is easier to clean than conventional mesh drums and can improve juicing efficiency.

[0143] In addition, the problem of mesh holes clogging in conventional mesh drums is fundamentally resolved, eliminating the need for the brush that conventional vertical juicers had to have, and also eliminating the need for various parts to drive the brush. Explanation of the symbols
