juicer
[0001] The present invention relates to a juicer.
[0002] Conventional juicers produce juice by feeding the ingredients into a hopper and crushing them with rotating blades.
[0003] The juicer required juicing material of an appropriate size depending on the size of the screw, and to this end, there was the inconvenience of having to cut the juicing material into the appropriate size before feeding it into the input port.
[0004] Furthermore, if the amount of prepared juicing material exceeds the capacity of the hopper and cannot be fed into the hopper all at once, the remaining material must be added only after the processing of the previously fed material is gradually completed. When additional material is fed, the hopper juicer typically stops operation to ensure user safety. In such cases, there is the inconvenience of having to frequently check the completion status of the previously fed material and restart the hopper juicer.
[0005] To address this, a related prior art document (Republic of Korea Utility Model Publication No. 20-2021-0000946 (May 3, 2021)) describes a hopper having a cutting section that automatically pre-cuts the juicing material when a large quantity of material is loaded, without the need for manual pre-cutting.
[0006] When examining the hopper configuration of a conventional juicer, a hopper housing is configured with an open top and a cutting part mounted on the bottom surface. The cutting part is composed of an upper blade (striking blade) and a lower blade (cutting blade), and ribs are formed on the inner wall of the hopper housing corresponding to this, so that the material is secondarily crushed / cut by the upper blade (striking blade) and the ribs, and the juice material is pushed out through a discharge hole formed at the bottom and discharged along with being secondarily crushed / cut by the lower blade (cutting blade).
[0007] Here, the reason for dividing into an upper blade and a lower blade is that large materials must be cut and crushed by a height difference. In one embodiment, when crushing an apple, if only the lower blade is configured without the upper blade, there is a problem of it spinning idly at the top, and conversely, if only the upper blade is configured, the crushed and reduced juice material cannot escape through the discharge hole.
[0008] The crushed and cut juicing material is discharged into a juicing drum connected to the bottom of the hopper housing, and is crushed and compressed by a screw and a juicing mesh to proceed with juicing.
[0009] Conventional juicers have an open top section for the cutting part, and the upper part of the rotational center of the cutting part is formed lower than the upper blade. This is intended to allow the material to be placed on top of the rotational center and crushed by the upper blade (crushing blade).
[0010] A conventional juicer configured in this way has the advantage of allowing the juice material to come into direct contact with the upper blade, so that a juice material larger than the distance from the center axis of the cutting section of the hopper housing to the inner wall of the hopper housing can be cut in one go with the upper blade.
[0011] However, conventional juicers are configured to have an open upper section for cutting large juice materials at once, which causes the load on the cutting section to increase and break due to juice materials larger than the hopper radius. Additionally, because the central axis is low, the juice materials settle on the upper part of the rotation center and spin freely. Furthermore, when cutting juice materials larger than the hopper radius in the first stage and sending them out through the discharge hole, if the speed at which the material is sent from the hopper exceeds the speed at which the screw can process it within the juice mesh space, there is a problem where the screw spits the material back out (backflow).
[0012] The present invention aims to provide a juicer that can prevent damage caused by large juicing materials and increase the durability of the device through a cutting part provided in the juicer, prevent the juicing material from spinning freely above the center of rotation, and prevent backflow from the discharge hole.

[0029] In addition, in a juicer according to one aspect of the present invention, the lower blade of the cutting portion is formed in a shape in which a plate-shaped blade is inclined upward or downward toward the front in the rotational direction.
[0030] In addition, in a juicer according to one aspect of the present invention, the lower blade of the cutting portion forms a lower front inclined surface and a lower pressure inclined surface formed to be inclined downward in the rotational direction; the lower front inclined surface has different angles of inclination on the outside and inside, and the outer inclined surface is formed higher relative to the bottom, so that the juice material can be gathered from the outside to the inside.
[0031] In addition, in a juicer according to one aspect of the present invention, the lower blade of the cutting portion forms a lower forward inclined surface and a lower pressure inclined surface formed to be inclined downward in the rotational direction; and the lower pressure inclined surface is characterized by applying downward pressure to the juice material.
[0032] In addition, in a juicer according to one aspect of the present invention, the lower blade of the cutting portion is formed to be inclined forward to form a lower pressure inclined surface in front, and the lower pressure inclined surface prevents the juice material from sliding over the lower blade and pressurizes the juice material downward.
[0033] In addition, in a juicer according to one aspect of the present invention, the lower blade of the cutting portion is characterized by being raised in a parallel or inclined manner as it extends radially from the center, so that the juice material does not slide over the lower blade.
[0034] In addition, in a juicer according to one aspect of the present invention, a material conveying blade is formed at the end of the lower blade so as to correspond to the second rib and lower than the upper end of the lower blade.
[0035] In addition, in a juicer according to one aspect of the present invention, the bottom surface of the lower blade of the cutting part is formed at a certain angle with the bottom surface of the hopper.
[0036] In addition, in a juicer according to one aspect of the present invention, the inner wall of the hopper is composed of a first section corresponding to the height of the lower blade and a second section corresponding to the height of the upper blade from the upper part of the lower blade; and the arc radius of the second section is formed to be larger than that of the first section.
[0037] In addition, in a juicer according to one aspect of the present invention, the first rib and the second rib have different protrusion heights, and the first rib may be formed higher toward the center of the hopper.
[0038] In addition, in a juicer according to one aspect of the present invention, the first rib and the second rib are formed at different positions to distribute the load received by the upper blade from the juice material.
[0039] In addition, in a juicer according to one aspect of the present invention, a discharge hole connected to a juice drum and a juice net installed inside the juice drum is formed on the bottom surface of the hopper, and the discharge hole may be formed in a fan shape.
[0040] In addition, in a juicer according to one aspect of the present invention, the position of the discharge hole is formed at a different location that does not overlap vertically with the first rib and the second rib, so that it can be positioned away from the lower position of the first rib and the second rib where the material breaks the most.
[0041] In addition, in a juicer according to one aspect of the present invention, a bottom cutting rib is formed on the bottom surface of the hopper to correspond to the lower surface of the lower blade, thereby inducing the cutting of the juice material and discharge through the discharge hole.

[0043] In addition, in a juicer according to one aspect of the present invention, the lower blade is formed to be inclined forward to form a lower pressure inclined surface at the front, and the lower pressure inclined surface prevents materials from sliding over the lower blade and can press the juice material downward.
[0044] In addition, in a juicer according to one aspect of the present invention, a lower tip edge is formed at the upper end of the lower blade, and the lower tip edge can form a step forward so that the juice material does not deviate from the lower pressure inclined surface when the material is pressurized by the lower pressure inclined surface.

[0070] A preferred embodiment according to the present invention will be described in detail below with reference to the attached drawings.
[0071] The advantages and features of the present invention and the method for achieving them will become clear by referring to the embodiments described in detail below together with the accompanying drawings.
[0072] However, the present invention is not limited by the embodiments disclosed below but may be implemented in various different forms, and these embodiments are provided merely to make the disclosure of the present invention complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims.
[0073] In addition, in describing the present invention, if it is determined that related known technologies, etc., may obscure the essence of the present invention, a detailed explanation thereof will be omitted.
[0074] Referring to FIGS. 1 to 8, the juicer according to the present invention may include a juice drum (10) formed to crush and press a juice material and accommodate a screw in an internal space, a hopper (50) coupled to the juice drum (10) and having a space formed to accommodate a juice material inside and including a rib (51, 52) formed protruding in the direction of a central axis at one end of an inner surface, a cutting part (100) rotatably coupled to the hopper (50) and cutting the juice material, and all or part of a main body (not shown).
[0075] Additionally, a juicing net (30) may be provided inside the juicing drum (10), and a scraper (20) capable of removing residue located on the juicing drum and the juicing net may be provided.
[0076] At this time, the cutting portion (100) is characterized by ensuring that the juice material is not placed on the rotation center portion and is cut sequentially from the lower portion to the upper portion of the juice material.
[0077] That is, the juicer can expand the capacity of the juice material, and even if the user feeds large juice material into the hopper that has not been cut into small sizes in advance, it is cut primarily by the cutting part (100) before reaching the screw (40), so the user has less trouble processing the juice material.
[0078] In addition, a lever part (70) may be provided so that the hopper (50) can be easily attached to and detached from the juicing drum (10).
[0079] The lever part (70) can be locked and fixed by the lever part (70) when the hopper (50) is connected to the juice drum (10) and the hopper (50) is seated on the upper part of the juice drum (10) and rotated clockwise or counterclockwise.
[0080] Additionally, when separating the hopper (50) from the juice drum (10), if you press the lever (79) which is provided protruding upward on the lever part (70) while gripping the handle (60) of the hopper (60), it is automatically released, making separation easier.
[0081] In addition, the juicer according to the present invention, more specifically, has a cutting section (100) that includes an upper blade (110), a lower blade (120), and a central axis blade (130).
[0082] The upper blade (110) is formed by extending radially from the center of rotation and is positioned above the lower blade (120) to cut the juice material.
[0083] The lower blade (120) is positioned on the bottom surface of the hopper and can cut and pressurize the juice material on the bottom surface of the hopper.
[0084] The central axis blade (130) is formed to extend upward from the center of rotation so as to prevent the juice material from being placed or received on the center of rotation of the cutting part, thereby solving the problem of the juice material spinning freely on the center of rotation.
[0085] Therefore, to solve the problem of the juice material of a conventional juicer spinning freely above the center of rotation, the central axis of the cutting section was formed to be equal to or higher than the height of the upper surface of the upper blade.
[0086] As shown in FIG. 4, this prevents the juice material (I), which is larger than the hopper radius relative to the center (C) of the hopper, from entering directly into the side of the upper blade (110) and causes the juice material to be cut sequentially from the bottom to the top, thereby reducing the load on the upper blade (110) by crushing it first from the center and feeding it into the upper blade (110), which prevents damage to the cutting part and increases the durability of the device.
[0087] In addition, by raising the central axis through the central axis blade (130), the juice material is prevented from settling or being received on the rotational center of the cutting section (100), thereby solving the problem of the juice material spinning freely on the rotational center and allowing even small juice materials to fall quickly to the bottom of the hoppers on both sides by moving away from the central axis.
[0088] That is, small juicing materials can be guided by the shape of the central axis blade (130) and move away from the central axis blade (130), or stirred by the central axis blade (130) and move away from the central axis and fall to the bottom of the hopper.
[0089] As a result, a series of problems caused by overfeeding juicing materials larger than the radius of the hopper or smaller juicing materials into the hopper can be prevented.
[0090] As shown in FIG. 5, the hopper (50) is configured with a lid (90) that is open at the top and rotates by a hinge, and the inner wall of the hopper (50) can be formed with the same diameter.
[0091] Additionally, a first rib (51) corresponding to the upper blade (110) may be formed protrudingly on one side of the inner wall of the hopper (50), and a second rib (52) corresponding to the lower blade (120) may be formed protrudingly on the other side of the inner wall of the hopper (50).
[0092] Additionally, the diameter of the inner wall of the hopper (50) can be formed such that the upper diameter (d2) is narrower and the lower diameter (d1) is wider due to the first rib (51) formed on one side of the inner wall of the hopper (50), and can be formed such that it widens from the top to the bottom.
[0093] That is, the arc radius of inner wall section 1 (d1) is larger than that of inner wall section 2 (d2).
[0094] The second inner wall section (d2) corresponds to the upper height of the upper blade (110) or the central axis blade (130), and the first inner wall section (d1) may correspond to the height of the lower blade (120).
[0095] Additionally, the first rib (51) can be formed in a slanted shape from top to bottom, so that the upper side corresponds to the upper blade (110) and the lower side can be formed so that the lower blade (120) passes through.
[0096] That is, the first rib (51) is formed to be inclined from the top to the bottom, so as to accommodate various sizes and shapes of juice materials, and the juice material can be naturally transported downward along the inclined surface and pressurized to prevent slippage.
[0097] Therefore, no matter what height the juice material is positioned at, the first rib (51) presses the juice material, thereby preventing the juice material from bouncing upward by the cutting part (100).
[0098] In conventional hopper-type juicers, the juice material enters in the direction of the central axis and the blade, such as the cutting part, cuts the side of the juice material, so there is less chance of the juice material bouncing away. However, in the present invention, in the case of large juice materials, crushing begins from the bottom, and especially when cutting spherical juice materials such as apples, the rolling and upward motion is strong, so an inclined surface that applies downward pressure, such as the first rib (51), is required.
[0099] Additionally, the first rib (51) and the second rib (52) provided in the hopper (50) have different protrusion heights, and the first rib (51) may be formed higher toward the center of the hopper.
[0100] In addition, the first rib (51) and the second rib (52) are formed at different positions and have the effect of dispersing the load received by the upper blade (110) from the juice material.
[0101] That is, the first rib (51) and the second rib (52) are formed at different locations, and it is preferable to form them at opposite locations to distribute the load.
[0102] Additionally, the lower part of the second rib (52) is left empty so that the end of the lower blade (120) can pass underneath it.
[0103] Additionally, the second rib (52) may be formed to have an incline or curvature in the direction in which the cutting portion (100) rotates.
[0104] This can be transported in a rotational direction along the curved surface so that it does not remain stagnant on the side of the second rib (52) of the object to be squeezed.
[0105] Additionally, as shown in FIGS. 6 and 7, a discharge hole (59) is formed at the bottom of the hopper (50) and connected to the juice drum (10) and the juice net (30) installed inside the juice drum, and the discharge hole (59) is formed in a fan shape.
[0106] Additionally, by forming the discharge hole (59) at a different location that does not overlap vertically with the first rib (51) and the second rib (52), it is positioned away from the lower location of the first rib (51) and the second rib (52) where the juice material is most broken, thereby preventing the juice material from being excessively discharged.
[0107] That is, this is because when the juice material is broken and falls to the bottom of the hopper first, the material is dispersed and can be sequentially transported to the discharge hole (59).
[0108] In addition, a bottom cutting rib (57) is formed on the bottom (56) of the hopper (50) so as to correspond to the lower blade (120) of the cutting section (100), thereby allowing the juice material to be cut and discharged through the discharge hole (59).
[0109] Additionally, the bottom cutting rib (57) may be formed with a height that gradually increases upward in the transverse direction relative to the rotation center axis, or with a constant height.
[0110] That is, the bottom cutting rib (57) is formed at the end of the discharge hole (59) in the rotational direction so as to cut the juice material and guide it to be discharged into the discharge hole (59).
[0111] Additionally, at least one hopper bottom rib (58) is formed on the bottom of the hopper (50) at a certain distance from the bottom cutting rib (57), so that when the lower blade (120) of the cutting section (100) rotates, the hopper bottom rib (58) prevents the juice material from being wrapped around the lower blade.
[0112] That is, the hopper bottom rib (58) is positioned in a direction opposite to the rotational direction of the cutting section (100), cutting the juice material and pushing the juice material radially from the center.
[0113] Therefore, when the cutting part (100) rotates, it can cut leafy vegetables such as celery by crossing with the lower blade (120), thereby solving the problem of the juice material getting tangled.
[0114] Additionally, a discharge wing (53) is formed protruding from the center of the bottom of the hopper (50), and the juice material flowing into the center through the discharge wing (53) can be cut and pushed outward.
[0115] At this time, the discharge wing (53) is formed in a shape that contacts one end of the bottom cutting rib (57) or the hopper bottom rib (58), and is characterized by being pushed outward from the discharge wing (53) to induce discharge through the bottom cutting rib (57) or the hopper bottom rib (58) into the discharge hole.
[0116] Referring to FIG. 8, the upper blade (110) of the cutting section (100) can have an upper surface and a lower surface of equal thickness, and can be formed to be thicker from the center toward the end so as to withstand the load of the juice material.
[0117] In addition, the upper blade (110) of the cutting section (100) can form pressure transfer surfaces (111, 112) at the front and rear to perform the function of pressing the juice material.
[0118] Additionally, a material collection section (140) is formed between the upper blade (110) and the central axis blade (130) by a partition, preventing the juice material from being loaded or settled in between.
[0119] Additionally, at least one reinforcing member (141) may be formed in the material collection section (140), which is formed between the upper blade (110) and the central axis blade (130) to reinforce the material collection section (140), and is characterized by being able to easily transport the juiced material while preventing the material collection section (140) from being damaged due to the heavy load of the juiced material.
[0120] In addition, the reinforcing part (141) can prevent the juice material from sticking to the area of the material collection section (140).
[0121] In other words, thin fibrous materials, such as the peels of leafy vegetables or fruits, may adhere to the cut portion; to resolve this problem, the surface of the entire or partial area of the cut portion can be formed with curves to prevent the juicing material from sticking.
[0122] In addition, when the juicing material is located in the material collection section (140), the protrusion (135) of the blade (130) effectively gnaws and penetrates the lower surface of the material, preventing the material from spinning freely and allowing it to be crushed.
[0123] That is, a projection (135) is provided on one or both sides of the upper part of the central axis blade (130) so that the juice material, which is larger than the radius of the hopper, is sequentially cut from the lower part to the upper part.
[0124] Additionally, the lower blade (120) of the cutting section (100) may have a forward inclined surface (123) formed in a shape that is inclined downward toward the front of the rotational direction, with a conveying blade (121) for conveying the juice material and a plate-shaped blade. Furthermore, at the end of the lower blade (120) of the cutting section (100), a cutting surface (125) may be formed at a position lower than the top of the lower blade (120) to correspond to the second rib (52), thereby preventing the lower blade (120) from being damaged due to the load generated at the end of the lower blade (120).
[0125] That is, the lower blade (120) of the cutting part (100) is characterized by a front inclined surface (123) formed to be inclined downward in the rotational direction, with the angle of inclination on the outside and inside being different, thereby pressing the juice material downward.
[0126] In addition, the rear surface of the lower blade (120) can perform the function of gathering the juice material located behind the lower blade from the outside to the inside when rotated in the reverse direction, so the lower blade (120) is characterized by being able to pressurize and transport the juice material when rotated forward and backward.
[0127] Referring to FIGS. 9 to 13, when examining a juicer according to another embodiment of the present invention, since the basic configuration is similar to the aforementioned juicer, only the parts with different configurations will be described.
[0128] According to another embodiment of the present invention, the hopper (50) of the juicer is configured with a lid (90) that is open at the top and rotates by a hinge, and the inner wall of the hopper (50) can be formed in a shape where the upper diameter (d2) is wider and the lower diameter (d1) is narrower, and can be formed in a shape that narrows from the top to the bottom.
[0129] That is, the arc radius of the inner wall section 2 (d2) is larger than that of the inner wall section 1 (d1).
[0130] The reason the radius of the inner wall section 2 (d2) is larger than that of the inner wall section 1 (d1) is that the size of the juice material in contact with the upper blade and the lower blade is different, so the space becomes smaller towards the bottom to allow the crushed juice material to be collected densely.
[0131] The second inner wall section (d2) corresponds to the upper height of the upper blade, and the first inner wall section (d1) may correspond to the lower blade height.
[0132] In addition, the second inner wall section (d2) and the first inner wall section (d1) may be formed with a gradually decreasing radius or a rapidly decreasing radius.
[0133] That is, the inner wall of the hopper (50) is composed of a first inner wall section (d1) corresponding to the height of the lower blade (120) and a second inner wall section (d2) corresponding to the upper height of the upper blade (110) from the upper part of the lower blade (120), and the arc radius of the second section (d2) is formed to be larger than that of the first section (d1).
[0134] Additionally, a first rib (51) corresponding to the upper blade (110) may be formed protrudingly on one side of the inner wall of the hopper (50), and a second rib (52) corresponding to the lower blade (120) may be formed protrudingly on the other side of the inner wall of the hopper (50).
[0135] Additionally, the first rib (51) can be formed with a lower space empty so that the lower blade (120) can pass underneath it.
[0136] Additionally, the first rib (51) and the second rib (52) provided in the hopper (50) have different protrusion heights, and the first rib (51) may be formed higher toward the center of the hopper.
[0137] In addition, the first rib (51) and the second rib (52) are formed at different positions and have the effect of dispersing the load received by the upper blade (110) from the juice material.
[0138] That is, the first rib (51) and the second rib (52) are formed at different locations, and it is preferable to form them at opposite locations to distribute the load.
[0139] Additionally, the lower part of the second rib (52) is left empty so that the end of the lower blade (120) can pass underneath it.
[0140] Additionally, as shown in FIG. 13, a discharge hole (59) is formed at the bottom of the hopper (50) and connected to the juice drum (10) and the juice net (30) installed inside the juice drum, and the discharge hole (59) is formed in a fan shape.
[0141] Additionally, by forming the discharge hole (59) at a different location that does not overlap vertically with the first rib (51) and the second rib (52), it is positioned away from the lower location of the first rib (51) and the second rib (52) where the juice material is most broken, thereby preventing the juice material from being excessively discharged.
[0142] That is, this is because when the juice material is broken and falls to the bottom of the hopper first, the material is dispersed and can be sequentially transported to the discharge hole (59).
[0143] Referring to FIGS. 14 to 16, a second embodiment of the cutting portion (100) is shown, and the upper blade (110) can have an upper surface and a lower surface of equal thickness.
[0144] In addition, the upper blade (110) is formed to become thicker from the center toward the end so as to withstand the load of the juice material.
[0145] In addition, the upper blade (110) of the cutting section (100) can form pressure transfer surfaces (111, 112) at the front and rear to perform the function of pressing the juice material.
[0146] Additionally, a material collection section (140) is formed between the upper blade (110) and the central axis blade (130) by a partition, preventing materials from being loaded or settled in between.
[0147] Additionally, it is preferable to form a material receiving groove (145) on the upper side of the material collection section (140) between the central axis blade (130) and the upper blade (110), and the material receiving groove (145) receives the lower part of the juice material, particularly in a spherical shape. When the lower part of the juice material is received in the material receiving groove (145), the protrusion (135) of the central axis blade (130) effectively gnaws and digs into the lower surface of the material, preventing the material from spinning freely and allowing it to be crushed.
[0148] That is, a projection (135) is provided on one or both sides of the upper part of the central axis blade (130) so that the juice material, which is larger than the radius of the hopper, is sequentially cut from the lower part to the upper part.
[0149] Additionally, a material conveying blade (125) can be formed at the end of the lower blade (120) of the cutting section (100) so as to correspond to the second rib (52) and lower than the top of the lower blade (120).
[0150] Additionally, the bottom surface of the lower blade (120) can be formed at a certain angle (θ3) with the bottom surface of the hopper (56).
[0151] Additionally, the lower blade (120) of the cutting section (100) may be formed with a plate-shaped blade inclined upward or downward toward the front in the rotational direction.
[0152] That is, the lower blade (120) of the cutting section (100) forms a lower front inclined surface (121) and a lower pressure inclined surface (123) formed to be inclined downward in the rotational direction, and the lower front inclined surface (121) is characterized by having an outer inclination angle (θ2) and an inner inclination angle (θ1) that are different, and the outer inclination surface is formed higher relative to the bottom, thereby gathering the juice material from the outside to the inside.
[0153] In addition, the lower pressure inclined surface (123) of the lower blade (120) of the cutting section (100) is characterized by applying downward pressure to the juice material.
[0154] In addition, the rear surface of the lower blade (120) forms a lower rear inclined surface (122) that slopes upward when rotated in the reverse direction, so that when the user operates the reverse rotation, it can press the juice material located behind the lower blade downward, and thus the lower blade (120) is characterized by being able to press and transport the material in both forward and backward rotations.
[0155] Referring to FIGS. 17 to 19, a third embodiment of the cutting part of the present invention is shown, wherein the upper blade (210) has an upper front blade (211) formed in the rotational direction and an upper rear blade (212) formed on the rear side, the upper front blade (211) cuts and grinds the juice material, and the upper rear blade (212) can push or cut the juice material when rotated in reverse.
[0156] Additionally, the upper tip blade (211) has an upper pressure transfer surface (215) formed on its lower side, which serves to press the material cut by the upper tip blade (211) or the material located on the lower side downward.
[0157] In addition, the upper blade (210) is formed upward with the same thickness on both the upper and lower surfaces, and the upper blade is formed thicker and / or blunter toward the end so as to withstand the load of the juice material.
[0158] Additionally, a material collection section (240) is formed between the upper blade (210) and the central axis blade (230) by a partition, preventing materials from being loaded or settled in between.
[0159] It is preferable to form a material receiving groove (245) on the upper side of the material collection section (240) between the central axis blade (230) and the upper blade (210).
[0160] Therefore, large materials are first crushed by the central axis blade (230) and then transferred to the upper blade (210) and lower blade (220). Since the juice material that was first crushed by the central axis blade (230) enters the side of the upper blade (210), over-feeding is prevented, and the overall load of the cutting section (100) is reduced.
[0161] In addition, the central axis blade (230) can also quickly separate and drop small juicing materials to the bottom of the hoppers on both sides.
[0162] That is, by forming protrusions (235) on one or both sides to stir the small materials so that they do not spin around or clump together in the center of the cutting section (100), the juiced materials are transported from the center of the cutting section (100) to the side in the direction of rotation of the cutting section, so that the juiced materials can be easily crushed by the upper blade (210) and the lower blade (220) or quickly fall to the bottom of the hopper.
[0163] Therefore, it can serve not only to separate the cutting section (100) so that it is not constrained when a large number of small materials are fed and clumped together, but also to quickly discharge small materials that do not require prior cutting into the discharge hole (59) at the bottom of the hopper.
[0164] Additionally, the central axis blade (230) is formed to be equal to or higher than the highest upper surface of the upper blade (210), preferably formed to be at least 0mm to 5mm.
[0165] That is, if the height of the central axis blade (230) is formed too high compared to the height of the upper blade (210), large juicing materials cannot be fully fed into the hopper, so it is desirable to form it at a constant height.
[0166] In addition, the distance between the outer surface of the central axis blade (230) and the inner wall of the hopper (50) is preferably 85 mm or less, which is similar to the average size of an apple, which is a spherical juicing material.
[0167] If the distance between the inner walls of the hopper housing is greater than this, a large load is generated when the juicing material enters, so it is desirable that the distance between the outer surface of the central axis blade (230) and the inner wall of the hopper (50) be formed at a constant distance.
[0168] Additionally, the lower blade (220) of the cutting section (100) may be formed in a shape in which the plate-shaped blade is tilted toward the front in the rotational direction.
[0169] The lower blade (220) is formed to be inclined forward to form a lower pressure inclined surface (221) at the front, and the lower pressure inclined surface (221) prevents materials from sliding over the lower blade and instead serves to press the materials downward.
[0170] Additionally, a lower tip edge (222) is formed at the top of the lower blade (220), and the lower tip edge (222) forms a step forward so that the juicing material does not deviate from the lower pressure slope surface (221) when the material is pressurized by the lower pressure slope surface (221).
[0171] In addition, the upper surface of the lower blade (230) is formed to become parallel or inclined as it increases in the radial direction so that the juice material does not easily pass over the lower blade.
[0172] Additionally, a material conveying blade (235) can be formed at the end of the lower blade (230) so as to correspond to the second rib (52) of the hopper (50) and lower than the top of the lower blade.
[0173] Additionally, the bottom surface of the lower blade (230) is formed to spread out at a certain angle (θ3) relative to the bottom surface of the hopper (56) and the discharge hole (59). This is because when the bottom surface of the lower blade rotates while attached parallel to the bottom surface of the hopper (56), it is too closely attached, causing the juice material to be cut into small pieces and generating a large amount of powder. In the case of hard seeds, conventional hopper-type juicers had the problem of the seeds getting stuck in the bottom surface of the lower blade and being damaged.
[0174] Therefore, the bottom surface of the lower blade forms a constant angle (θ3) with the bottom surface of the hopper, and an angle of about 3 to 5 degrees is most desirable.
[0175] For reference, the bottom surface of the lower blade can be formed parallel to the entire surface without being formed at a specific angle; however, in this case, there is a problem in that small materials accumulate axially on the bottom surface of the lower blade and are not discharged into the discharge hole.
[0176] Therefore, the bottom surface of the lower blade is formed as close as possible to the bottom surface of the hopper near the shaft, but forms a certain angle with the bottom surface of the hopper so that the juicing material can be pushed out in the radial direction.
[0177] In addition, it is not necessary for the entire structure to be sloped; instead, it can be formed parallel to the floor for a certain length from the axis section and sloped from the inner end of the discharge hole.
[0178] Referring to FIG. 20, this is a drawing showing a fourth embodiment of the cutting portion of the present invention.
[0179] The upper blade (310) of the cutting section (100) can be formed by extending horizontally in a radial direction from the top of the central axis blade (330).
[0180] In addition, a projection (335) is provided on one or both sides of the upper part of the central axis blade (330) of the cutting section so that the juice material, which is larger than the radius of the hopper, is sequentially cut from the lower part to the upper part.
[0181] FIGS. 21 to 23 are drawings showing a juicer according to another embodiment of the present invention.
[0182] A juicer according to another embodiment of the present invention may be equipped with a separate extension hopper (80).
[0183] The hopper (50) may be formed in a tubular shape with the top and bottom open to form a receiving space, and an extension hopper (80) or a lid (90) may be mounted on the top of the hopper (50).
[0184] That is, a lid (90) can be mounted on the upper part of the hopper (50), an extension hopper (80) can be mounted on the upper part of the hopper (50), and a lid (90) can be mounted on the upper part of the extension hopper (80).
[0185] This allows the storage space for the juicing material to be freely expanded and contracted, making storage easier and improving the convenience of use.
[0186] Accordingly, according to the present invention, the cutting part provided in the juicer can prevent damage caused by large juicing materials and increase the durability of the device, prevent the juicing material from spinning freely above the center of rotation, and prevent backflow from the discharge hole.
[0187] Although specific embodiments of the juicer according to the present invention have been described so far, it is obvious that various modifications are possible within the scope of the present invention.
[0188] Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
[0189] That is, the aforementioned embodiments should be understood as exemplary in all respects and not limiting, and the scope of the invention is defined by the claims set forth below rather than by the detailed description, and all modifications or variations derived from the meaning and scope of the claims and their equivalents should be interpreted as being included within the scope of the invention.
