Description

[Technical field]

[0001] The present invention relates to a juicing module for a juicer, and more particularly to a juicing module for a juicer having an improved structure that eliminates the need to cut an object to be juiced before it is fed into the module. [Background technology]

[0002] Typically, the juicing module includes a juicing drum having a juicing space, a cover body having an inlet for introducing the object to be juiced into the juicing drum, a screw for juicing the object to be juiced in the juicing drum, and a mesh body for separating the juice from the residue. The main body also includes a drive motor for rotating the screw, and the shaft of the drive motor is connected to the screw in the juicing module.

[0003] However, in conventional juicers, the material to be juiced must be cut into pieces that can be juiced by the screw before it is fed into the screw. For example, Korean Patent Registration No. 10-0793852 discloses a juicer technology configured to cut or chop the material to be juiced with a blade of the screw that protrudes from the rotation axis of the screw to one side of the top end.

[0004] However, with this technique, when the size of the object to be juiced is larger than the length of the blade of the screw, the object to be juiced must be cut in advance to a size smaller than the length of the blade of the screw before being fed.

[0005] In addition, Korean Patent Registration No. 10-0966607 discloses a juicer technology in which a steel plate is installed over the entire upper surface of the screw to crush the object to be juiced just before squeezing the juice.

[0006] However, crushing using a steel plate requires high-speed crushing, not the low speed inherent to juicers, and there is a problem that the user must apply a large force to squeeze the object to be juiced against the steel plate in order to prevent the object from rotating due to the high speed of the steel plate.

[0007] In addition, in conventional juicers, after cutting the object to be juiced, the cut pieces are crushed while being squeezed by the mesh during the juicing process, causing the mesh to instantly deform due to the squeezing of the cut pieces.

[0008] This phenomenon destroys the extruded material that maintains the shape of the net body, or reduces the binding force between the extruded material and the net body, resulting in the generation of gaps between the extruded material and the net body, which causes residue to leak out and reduces the juice extraction rate. Summary of the Invention [Problem to be solved by the invention]

[0009] Therefore, the present invention aims to reduce the load on the motor connected to the screw by forming a crushing section and a support surface at the upper end of a screw rotating at a low speed and primarily crushing the material to be squeezed before it reaches the helical ribs of the screw.

[0010] In addition, the present invention aims to enable a user to insert the object to be juiced without cutting it by dividing the object into either a small diameter inlet or a large diameter inlet depending on the size of the object.

[0011] In addition, the present invention aims to enable users to conveniently feed objects to be squeezed into the inside of the juicing drum regardless of their size by having the object to be squeezed fed into a small diameter inlet be preferentially crushed by the crushing section, and having a portion of the object to be squeezed fed into a large diameter inlet reach the spiral of the screw immediately, while the remaining portion is preferentially crushed by the crushing section.

[0012] Another object of the present invention is to provide a juicing module for a juicer, which can omit the complicated process of cutting or milling the object to be juiced before being fed into the feeding section by providing the lid body and the screw with a structure for pre-crushing the object to be juiced.

[0013] In addition, in order to feed the object to be juiced through the input section without cutting or milling it in advance, it is unavoidable to expand the size of the input section, but when the input section is enlarged, there is a risk that a person's, particularly a child's, finger may get into the input section and reach the screw. The present invention aims to provide a juice extraction module that prevents such a risk. [Means for solving the problem]

[0014] The juicing module of the double input structure of the present invention includes a juicing drum which contains a mesh body inside and is connected to the upper end of a main body and has a lid body connected to the upper part through which the material to be juiced is input, and a screw which is mounted inside the mesh body and rotates based on the screw rotation axis, has spiral ribs formed on its outer circumferential surface, and receives the material to be juiced from the lid body and crushes it, the screw is formed in a direction intersecting the screw rotation axis and includes a support surface which supports the material to be juiced input into the lid body, and a crushing section which is formed at the upper end intersecting the support surface and cuts the material to be juiced, the lid body includes an input port through which the material to be juiced is input, and the input port guides the material to be juiced to reach the spiral rib or the support surface.

[0015] In addition, the double-feed structure juicing module of the present invention includes a juicing drum that houses a mesh body inside and is connected to the upper end of the main body, and an inlet through which the material to be juiced is fed in, which is formed with at least two or more paths, a lid body that is connected to the upper end of the juicing drum, and a screw that is attached inside the mesh body and has spiral ribs formed on its outer circumferential surface and receives the material to be juiced from the inlet and crushes it, and the screw includes a crushing section at its upper end that cuts the material to be juiced, and a support surface that supports a portion of the material to be juiced fed into the inlet. Effect of the Invention

[0016] To achieve the above object, the juice extraction module of the present invention forms a crushing section and a support surface at the upper end of a screw rotating at a low speed, and primarily crushes the object to be juiced before it reaches the helical rib of the screw, thereby reducing the load on the motor connected to the screw.

[0017] In addition, the juicing module of the present invention allows the user to feed the object to be juiced into either the small diameter inlet or the large diameter inlet depending on the size of the object, without cutting it.

[0018] In addition, the juicing module of the present invention allows the object to be juiced fed into the small diameter inlet to be preferentially crushed by the crushing section, and allows a portion of the object to be juiced fed into the large diameter inlet to reach the spiral of the screw immediately, while the remaining portion is preferentially crushed by the crushing section, allowing the user to conveniently feed the object to be juiced regardless of its size.

[0019] In addition, the juicing module of the present invention has a structure in the lid body and the screw for pre-crushing the object to be juiced, thereby eliminating the complicated process of pre-cutting or milling the object to be juiced using the input section before being input.

[0020] Furthermore, in order to feed the object to be juiced through the input section without first cutting or milling it, it is unavoidable to expand the size of the input section. If the input section is made larger, there is a risk that people's, particularly children's, fingers may get stuck in the input section and reach the screw, but the juice extraction module of the present invention can prevent such a danger.

[0022] Some embodiments of the present invention will be described in detail below with reference to the drawings. When referring to components in each drawing, it should be noted that the same components are referred to by the same reference numerals as much as possible even if they are shown in different drawings. In addition, when describing the present invention, if it is determined that a detailed description of related known configurations or functions may make the gist of the present invention unclear, the detailed description will be omitted.

[0023] In describing components of the embodiments of the present invention, reference numerals such as 1, 2, i), ii), a), b) are used. Such reference numerals are used to distinguish the components from other components, and do not limit the essence, order, or procedure of the components. When a part in the specification "has" or "includes" a certain component, this does not mean that the other component is excluded, but that the part further includes the other component, unless explicitly stated to the contrary.

[0024] One embodiment of the present invention provides a juicing module with a double input structure, comprising: a juicing drum that houses a net body inside and is connected to the upper end of a main body and has a lid body connected to an upper part thereof, into which the object to be juiced is input; and a screw that is mounted inside the net body, rotates based on a screw rotation axis, has a spiral rib formed on its outer periphery, and receives and crushes the object to be juiced from the lid body. The screw is formed in a direction intersecting with the screw rotation axis, and has a support surface that supports the object to be juiced input into the lid body and a crushing part formed at the upper end intersecting with the support surface to cut the object to be juiced, and the lid body has an input port that guides the object to be juiced to reach the spiral rib or the support surface.

[0025] 1 to 16, a juicing module 10 having a double input structure according to an embodiment of the present invention includes a juicing drum 100, a mesh body 200, a screw 300, a cover body 400, and a main body 500 in whole or in part.

[0026] The coupling relationship of the components of the present invention will be described below. The juicing module 10 of the double input structure according to one embodiment of the present invention includes a juicing drum 100 having a juicing space therein and a residue outlet 110 and a juice outlet 150 formed on one side and the other side of the outer surface, a mesh body 200 installed inside the juicing drum 100 to separate the juice from the residue generated when juicing the object to be juiced, a screw 300 installed inside the mesh body 200 to squeeze the object to be juiced, a cover body 400 installed at the upper end of the juicing drum 100 and having a large diameter input port 410 and a small diameter input port 420 formed therein through which the object to be juiced is input, and a main body 500 coupled to the lower end of the juicing drum 100.

[0027] Although not shown, the juicing module 10 of the double input structure according to one embodiment of the present invention may employ an opening / closing means for selectively opening and closing the squeezed liquid outlet 150 of the juice drum 100. Although not shown, the juicing drum 100 may employ an opening / closing means for selectively opening and closing the squeezed liquid outlet 150. As the opening / closing means, a cock valve may be used, and the cock valve preferably has a valve body that advances or retreats through the squeezed liquid outlet 150, and has a structure in which the tip of the valve body is oriented toward the squeezed liquid outlet 150. Meanwhile, various means for opening and closing the squeezed liquid outlet 150 other than the above structure may be employed.

[0028] 2 and 3, the juice squeezing drum 100 includes a residue discharge port 110, an upper base 120, a lower base 130, a packing portion 140, and a juice discharge port 150, all or part of which.

[0029] The juice squeezing drum 100 in Fig. 2 has a different shape from the juice squeezing drum 100 in Fig. 3. In the embodiment of the present invention, in addition to the juice squeezing drum 100 shown in Fig. 2 and Fig. 3, any type of drum capable of connecting the screw 300 and the lid body 400 can be used.

[0030] The juice extracting drum 100 in FIG. 2 is a general drum, while the juice extracting drum 100 in FIG. 3 is characterized in that the residue discharge port 110 is slidably coupled.

[0031] A lid 400 is removably attached to the juice squeezing drum 100. The juice squeezing drum 100 is also formed with a residue discharge outlet 110 on one side and a squeezed juice discharge outlet 150 on the other side.

[0032] The upper base 120 is formed integrally with the juice extracting drum 100, and the lower base 130 is provided so as to be engageable with the upper base 120.

[0033] The packing unit 140 prevents the filtered residue and finely squeezed juice in the residue from leaking from the gap between the upper base 120 and the lower base 130 when the screw 300 squeezes the juice from the object to be squeezed. Here, the packing unit 140 is a general type of packing.

[0034] Meanwhile, a packing groove (not shown) is formed at the lower part of the packing part 140. A packing fixing protrusion formed on the lower base 130 can be attached or detached to or from the packing groove.

[0035] Meanwhile, the upper base 120 and the lower base 130 of the residue discharge port 110 are formed to have a separable structure. For example, the upper base 120 and the lower base 130 are connected to each other by a slide hinge.

[0036] In one embodiment of the present invention, when a user wants to open the residue discharge port 110, the user can separate the slide fixing part 131 from the upper base 120 to release the fastened state therebetween.

[0037] The juice outlet 150 is configured to be inclined downward so that the squeezed juice can be smoothly discharged to the outside. The juice outlet 150 further has a juice opening / closing opening (not shown) at one end configured to prevent the juice from being discharged to the outside or to allow the juice to be discharged to the outside.

[0038] Referring to FIG. 4, the net body 200 includes all or some of a punched net 210, a lower punched net 215, squeezing ribs 220, and a lower squeezing rib 225.

[0039] The net body 200 is detachably attached to the juice extracting drum 100. The net body 200 has a predetermined shape, for example, a cylindrical shape.

[0040] The net 200 has a cylindrical shape with a space that gradually becomes wider toward the top.

[0041] A punched net 210 is formed on the outside of the net body 200, for example, on the entire outside or a part of the entire periphery. The punched net 210 is formed integrally with the net body by injection molding, or is formed detachably as a module.

[0042] Furthermore, the size of each of the at least one mesh hole formed in the punched mesh 210 may be the same or different. For example, the mesh hole formed in the upper part of the punched mesh 210 has a different size from the mesh hole formed in the lower part of the punched mesh 210. Furthermore, the lower punched mesh 215 is formed relatively more densely than the punched mesh 210 and has a smaller diameter.

[0043] The squeezing rib 220 and the lower squeezing rib 225 are disposed inside the net body 200 and are configured to cut, crush or squeeze the object to be squeezed inside the net body 200 in cooperation with the screw 300. The squeezing rib 220 and the lower squeezing rib 225 are configured in a plurality of pieces, and at least one of the squeezing ribs 220 is formed to be gradually thicker or thinner in the vertical direction corresponding to the spiral rib 310 formed on the screw 300. Meanwhile, the squeezing rib 220 and the lower squeezing rib 225 have different lengths in the vertical direction.

[0044] At least one lower squeezing rib 225 is formed uniformly or non-uniformly on the lower part of the net body 200. The lower squeezing ribs 225 may be formed in the same number as the squeezing ribs 220, or in a larger number.

[0045] Referring to FIG. 5, the screw 300 according to the present invention includes all or a part of a helical rib 310, a screw rotation axis 320, a conveying surface 330, a crushing portion 340, and a support surface 350, and the screw 300 is disposed inside the mesh body 200.

[0046] The spiral rib 310 is formed to incline downward from the upper end of the screw 300. For example, the spiral rib 310 is formed to connect from the upper side to the lower side of the screw 300 and extend in a radial direction from the uppermost end. The spiral rib 310 rotates together with the screw 300 and cuts the object to be juiced that has been put into the net body 200.

[0047] The screw rotation axis 320 is formed at the center of the screw 300 and is coupled to the main body 500. In the following, when describing the coupling relationship of the screw 300, the coupling relationship will be described by setting the screw rotation axis 320 as a reference. Here, setting the screw rotation axis 320 as a reference means that the coupling relationship will be described by using a straight line coinciding with the screw rotation axis 320 as a reference.

[0048] The transfer surface 330 is a predetermined plate formed at the upper end of the screw 300 and formed with a certain height and area. A crushing section 340 that cuts or crushes the object to be juiced inputted into the large diameter input port 410 or the small diameter input port 420 is formed above the transfer surface 330. Meanwhile, a support surface 350 extending from the crushing section 340 and formed at a certain angle is formed at the rear end of the transfer surface. The transfer surface 330 is located in the radial direction based on the screw rotation axis 320.

[0049] The crushing section 340 is formed at the upper part of the screw 300, that is, at the position where the conveying surface 330 and the support surface 350 are connected, and extends with a certain height and area. For example, the crushing section 340 is formed at an end higher than the spiral rib 310. The crushing section 340 is formed in a direction intersecting with the support surface 350, and a crushing blade 344 is formed at the upper end of the crushing section 340. For example, the support surface 350 is formed along the outer edge based on the screw rotation axis 320, so that it intersects with the screw rotation axis 320, and a part of the support surface 350 intersects with the crushing section 340. Meanwhile, the crushing section 340 is formed to intersect perpendicularly with the support surface 350. In addition, the crushing section 340 rotates based on the rotation direction of the screw 300, and primarily cuts the object to be squeezed that is input to the large diameter input port 410 or the small diameter input port 420. The crushing blade 344 formed at the upper end of the crushing section 340 is formed at an incline from the crushing section 340. For example, when the screw 300 is viewed from the side, the crushing blade 344 is formed at an incline while forming an inclination angle based on the screw rotation axis 320. Here, the inclination angle is formed in the direction in which the object to be squeezed is drawn into the crushing section 340. If the inclination angle is formed in the direction in which the object to be squeezed is drawn, when the object to be squeezed comes into contact with the crushing section 340, the object to be squeezed first comes into contact with the end of the crushing blade 344. When the object to be squeezed is cut, the part of the object to be squeezed that comes into contact with the end of the crushing blade 344 starts to be cut first, and then the upper end of the object to be squeezed moves in the direction of the support surface 350 beyond the crushing section 340. In this way, when the crushing blade 344 forms an inclination angle, it has the effect of preventing the object to be squeezed, such as a carrot, from flying out while being cut. In order to achieve such an effect, the more the inclination angle is inclined in the direction in which the object of juicing is drawn in, the more the effect is maximized. If the crushing blade 344 is not inclined with respect to the screw rotation axis 320, the object of juicing will break while contacting the surface area of ​​the crushing section 340, causing the object of juicing to fly off. Meanwhile, the crushing section 340 has an extension member 346 formed to extend in the outer edge direction of the support surface 350. The extension member 346 is not a member formed separately in the crushing section 340, but is a term that refers to the outer edge of the crushing section 340. In a first modified embodiment of the present invention described later, a crushing and accommodating groove (332 in FIG. 6) can also be formed at the position of the extension member 346. The crushing and accommodating groove 332 will be described separately.In one embodiment of the present invention, when the crushing unit 340 is formed to extend to the extension member 346, the phenomenon of the object of juicing colliding with the inner surface of the lid body 400 can be reduced. In contrast, when the crushing and accommodating groove 332 is formed at the position of the extension member 346, the crushing rib 460 formed on the inner surface of the lid body 400 is required for the screw 300 to efficiently crush the object of juicing. That is, the object of juicing is cut by the crushing and accommodating groove 332 and the crushing rib 460 crossing each other, so that the object of juicing often collide with the inner surface of the lid body 400. However, when the crushing unit 340 is formed to extend to the extension member 346, the screw 300 can efficiently crush the object of juicing even without the crushing rib 460 on the inner surface of the lid body 400, so that the phenomenon of the object of juicing colliding with the inner surface of the lid body 400 can be reduced. This technical feature increases the proportion of the space occupied by the crushing unit 340 among the spaces formed inside the lid body 400. This allows the crushing section 340 to cut the object to be juiced more effectively.

[0050] The support surface 350 is formed such that one side extends from the rear surface of the crushing unit 340 and the other side is connected to the front surface of the crushing unit 340. Here, the one side is formed at a relatively higher position than the other side. The support surface 350 is connected from one side to the other side, and a bent portion 355 is formed therebetween. The bent portion 355 is a bent surface formed so that the cutting surface of the crushing unit 340 forms an appropriate height when the object to be squeezed enters the crushing unit 340 and is cut. The bent portion 355 forms an inclined surface that is inclined so that the cutting surface of the crushing unit 340 forms an appropriate height. The upper portion of this inclined surface is formed in a convex shape. When the bent portion 355 is formed in a convex shape, it has the effect of cutting the object to be squeezed by the crushing unit 340 at an appropriate height. Thus, when designing the shape of the support surface 350, the degree of inclination of the bent portion 355 can be adjusted.

[0051] A protrusion 352 is formed on the periphery of the support surface 350, i.e., on the side surface, in a shape in which a part of the support surface 350 protrudes. When the object to be juiced flowing on the support surface 350 is pushed out to the periphery of the support surface 350, the object to be juiced is crushed by the protrusion 352 formed on the periphery of the support surface 350. The object to be juiced crushed by the protrusion 352 falls downward and is pulverized by the spiral rib 310 of the screw 300.

[0052] In the present invention, the protrusions 352 not only crush the object of juicing pushed to the periphery, but also flow the object of juicing. For example, vegetables such as celery are not crushed by the protrusions 352, but are pushed out by the protrusions 352 and flow.

[0053] In the following, with reference to FIG. 6, a first variant embodiment of the screw 300 mentioned in FIG. 5 will be described.

[0054] In the screw 300a according to the first modified embodiment of the present invention, a crushing and accommodating groove 332 of a certain size is formed in a part of the upper side of the conveying surface 330. That is, the crushing and accommodating groove 332 is formed in the upper side of the conveying surface 330, and the crushing and accommodating groove 332 is connected to the crushing unit 340. Compared to the screw 300 of FIG. 5 in which the extension member 346 is formed, the screw 300a of FIG. 6 has the crushing and accommodating groove 332 instead of the extension member 346.

[0055] The crushing and accommodating groove 332 is formed with an accommodating groove of a certain size, and the crushing ribs 460 protrude by the size of the crushing and accommodating groove 332 and interact with each other to not only cut the object to be squeezed but also drag the object to be squeezed (celery) that has not been cut and cause it to flow below the screw.

[0056] When the crushing and accommodating groove 332 is formed in the screw 300a, it is necessary to form a crushing rib 460 on the inner surface of the cover body 400. When the object to be squeezed is located in the empty space of the crushing and accommodating groove 332, the object to be squeezed is crushed by the crushing rib 460 when the screw 300a rotates.

[0057] In the following, a second modified embodiment of the screw 300b described in FIG. 5 will be described with reference to FIGS.

[0058] The second modified embodiment further includes the crushing accommodation groove 332, the accommodation portion 360, and the crushing portion entrance step 370 of the first modified embodiment. Descriptions of the same components as the screw 300 in Fig. 5 and the screw 300a in Fig. 6 will be omitted, and only the accommodation portion 360 and the crushing portion entrance step 370 formed in the screw 300b in Fig. 7 and Fig. 8 will be described.

[0059] The accommodating portion 360 is formed and connected to the other side of the supporting surface 350. Meanwhile, the other side of the supporting surface 350 is connected to the accommodating portion 360. For example, the other side of the supporting surface 350 is connected to an accommodating groove guide portion 362 that is inclined downward, thereby connecting the supporting surface 350 and the accommodating portion 360. Therefore, the height of the accommodating portion 360 is formed at a position relatively lower than the supporting surface 350.

[0060] One side of the accommodating section 360 is connected to the support surface 350, and the other side of the accommodating section 360 is connected to the crushing section entrance step 370. Meanwhile, one side end of the accommodating section 360 has an accommodating groove guide 362 inclined at a predetermined angle so that the object to be squeezed placed on the support surface 350 is placed in the accommodating section 360. Also, the other side end of the accommodating section 360 has an upper flow step 364 inclined at a predetermined angle so that it is connected to the crushing section entrance step 370. Here, the accommodating groove guide 362 and the upper flow step 364 are both formed to be inclined upward with respect to the accommodating section 360. Also, a lower flow step 366 formed in a shape similar to the inclined surface of the accommodating groove guide 362 is formed below the accommodating groove guide 362. The lower flow step 366 is formed to reduce the cost and weight of the screw 300b.

[0061] Here, the upper flow stage 364 is formed with an inclined surface such that the long object to be squeezed lies between the storage section 360 and the crushing section entrance stage 370. Therefore, the long object to be squeezed is put into the large diameter inlet 410 or the small diameter inlet 420, and then passes through the support surface 350 and the storage groove guide section 362 in order, and is placed at a relatively low position, i.e., in the storage section 360. Next, before being cut by the crushing section 340, the long object to be squeezed lies in the crushing section entrance stage 370 while inclining in contact with the upper flow stage 364. That is, the long object to be squeezed lies between the storage section 360 and the crushing section entrance stage 370, engaged with the upper flow stage 364.

[0062] As a result, the inclined object to be squeezed is crushed and cut by crossing the crushing section 340 formed on the upper side of the conveying surface 330 and the crushing ribs 460 formed on the inner side of the hopper 430 .

[0063] Referring to FIG. 9, (a) is a diagram showing a screw 300a according to a first modified embodiment, and (b) is a diagram showing a screw 300b according to a second modified embodiment.

[0064] The screws 300a, 300b of the juicing module 10 having a double input structure are formed with a first space portion 301, a second space portion 302, a third space portion 303 and a cutting portion 304. Meanwhile, a spiral rib 310 is formed on the outer surface of the screws 300a, 300b, and a screw rotation shaft 320 is formed at the center.

[0065] The first space 301, the second space 302, and the third space 303 are formed in a rotating plate shape on the upper side of the screw rotation shaft 320. The first space 301, the second space 302, and the third space 303 are formed perpendicular or inclined to the cutting portion 304. When the cutting portion 304 is formed perpendicularly, the area of ​​contact with the object to be juiced is minimized, and the crushing power of the cutting portion 304 can be increased.

[0066] The first space 301 , the second space 302 , and the third space 303 are formed by being continuously connected from the cut portion 304 in the rotation direction of the screw rotation shaft 320 .

[0067] Also, As shown in FIG. 9(b), in the screw 300b of the second modified embodiment, The area of ​​the first space 301 is formed at a position relatively lower than the remaining area, i.e., the second space 302 and the third space 303, and thus forms a step structure with the remaining area. Therefore, the object to be squeezed is lowered and cut by the height of this step structure. Here, the step structure is understood as a concept corresponding to a shown in FIG. 10(a) or as the difference in height between the cut portion 304 and the first space 301.

[0068] On the other hand, the second space 302 is formed between the first space 301 and the front surface of the cutting portion 304 , and the second space 302 is formed at a position relatively higher than the first space 301 .

[0069] In addition, one side of the third space portion 303 is connected to the rear surface of the cutting portion 304 and the other side is connected to the first space portion 301 .

[0070] The upper flow step 364 is formed to be inclined downward from the second space 302 to the first space 301 so as to connect the first space 301 and the second space 302 .

[0071] Further, the accommodation groove guide portion 362 is formed to be inclined downward from the third space portion 303 toward the first space portion 301 so as to connect the third space portion 303 and the first space portion 301 to each other.

[0072] Moreover, the protrusion 352 is formed by protruding a part of the periphery of the third space.

[0073] Hereinafter, the process in which the object to be juiced is cut and crushed when the screws 300a and 300b rotate will be described in more detail.

[0074] First, when an object to be juiced, for example, celery, is fed into large diameter inlet 410 or small diameter inlet 420, as screws 300a, 300b rotate, cutting section 304 at the upper end of screws 300a, 300b cuts only a portion of the celery. Here, cutting section 304 is a component corresponding to crushing section 340 in FIG. 5.

[0075] Next, a portion of the bottom end of the celery cut by cutting portion 304 falls into the side space between cutting portion 304 and second space portion 302. Alternatively, a portion of the bottom end of the celery falls into the side space between cutting portion 304 and third space portion 303. Meanwhile, the remaining portion of the celery that does not fall is crushed by crushing ribs 460 while moving along the vertical surface of cutting portion 304.

[0076] As shown in FIG. 9(b) and FIG. 16, in the screw 300b of the second modified embodiment, The uncut portion of the celery, i.e., the top end of the celery, is placed in the third space 303, and the screw -3 As the 00b rotates, the 00b moves in the direction of the first space portion 301, which is relatively low in height, and is placed in the first space portion 301.

[0077] Here, the first space 301 and the third space 303 are formed in a stepped structure, i.e., in a structure that forms a step. -3 When 00b rotates, the celery descends.

[0078] Meanwhile, second space 302 is formed in front of cutting portion 304, i.e., between first space 301 and cutting portion 304. Second space 302 drags the celery so that the thinner stalks of the uncut celery stalks are cut by cutting portion 304.

[0079] Third space 303 is a space for dragging the celery when first space 301 and second space 302 are unable to completely drag the celery, and is a space on which the celery is placed. A step having a partially protruding shape is formed on one outer end of third space 303. This step is a component that performs the same function as protrusion 352. When the object to be juiced flowing in third space 303 is pushed out to the periphery of third space 303, the object to be juiced is crushed by the step formed on the periphery.

[0080] That is, third space 303 is a component for dragging the thinner stalk portion of the celery, which has more leaves than the thick stalk. Thus, the thick stalk portion of the celery is cut or dragged in first space 301 and second space 302, and the thin stalk is dragged in third space 303.

[0081] Meanwhile, the above description shows the grinding process of vegetables similar to celery. If a hard object to be juiced such as a carrot is fed into the large diameter inlet 410 or the small diameter inlet 420, the carrot is cut by the cutting section 304 to the height of the cutting section 304, and then transported and ground.

[0082] In this respect, by adjusting the height of the cutting portion 304 of the present invention, the amount of the object to be juiced that is cut can be adjusted.

[0083] For example, if the cutting unit 304 is relatively high, a relatively larger amount of carrots is cut and crushed when the screws 300a, 300b rotate once. If the cutting unit 304 is relatively low, a relatively smaller amount of carrots is cut and crushed when the screws 300a, 300b rotate once. Therefore, the juicing module 10 with a double input structure according to an embodiment of the present invention can adjust the amount of cut of the object to be juiced. Meanwhile, if the vertical height of the cutting unit 304 is too low, there are cases where the object to be juiced, such as carrots, cannot be cut, so the cutting unit 304 must be formed at an appropriate height.

[0084] On the other hand, the blade length b of the cutting portion 304 is related to the function of dragging the object to be juiced. Here, the blade length b refers to b in FIG.

[0085] For example, in cutting section 304, if the length b of the blade that cuts the object to be juiced is relatively short, it becomes difficult to automatically feed the object to be juiced, such as celery. Here, automatic feeding refers to a series of processes, such as the process in which celery descends from third space section 303 to first space section 301 based on the rotation of screws 300a, 300b. Therefore, if the length b of the blade is too short relatively, a problem occurs in which the celery cannot be properly dragged, so the length b of the blade must be formed to be a predetermined length or more.

[0086] Furthermore, the cutting portion 304 is formed to have the longest diameter from the rotation axis compared to the first space 301, the second space 302, and the third space 303. If the cutting portion 304 is formed to have the longest diameter, when the object to be juiced is cut, for example, at the time when the cutting portion 304 passes through the small diameter inlet 420, almost no gap is formed between the lower end of the small diameter inlet 420 and the cutting portion 304. Therefore, the object to be juiced is cut by the cutting portion 304 without falling downward.

[0087] 11 to 13, the cover 400 includes a large diameter input port 410, a small diameter input port 420, a hopper 430, a input guide portion 440, and a rotating shaft receiving groove 450, all or part of which.

[0088] 12 and 13(b) is a modified embodiment of (a) shown in Fig. 12 and 13, and further includes a crushing rib 460 compared to (a). Therefore, (a) is a lid body 400 corresponding to the screw 300 in Fig. 5, and (b) is a lid body 400 corresponding to the screws 300a and 300b in Fig. 6 and 7. For convenience, the following description will be given based on the lid body 400 in (b).

[0089] The cover 400 is connected to the upper end of the juicing drum, and has a path, i.e., an inlet, through which the object to be juiced is introduced and guided to the spiral rib 310 or the support surface 350. Here, the large-diameter inlet 410, which will be described later, guides the object to be juiced to the spiral rib 310, and the small-diameter inlet 420 forms a path through which the object to be juiced reaches the support surface 350, thereby guiding the object to be juiced.

[0090] The large diameter inlet 410 is a path through which objects to be juiced that are relatively large in size are introduced, and the small diameter inlet 420 is a path through which objects to be juiced that are relatively small in size are introduced.

[0091] The hopper 430 is formed such that the path for introducing the objects to be juiced is divided into two parts inside the juice extracting drum 100. That is, the hopper 430 is formed with a large diameter inlet 410 through which large objects to be juiced are introduced, a small diameter inlet 420 through which small objects to be juiced are introduced, and a rotating shaft accommodating groove 450. Meanwhile, a crushing rib 460 is formed vertically inside the hopper 430 so as to protrude inward.

[0092] The input guide part 440 is formed at the lower end of the large diameter input port 410. Also, a part of the input guide part 440 is formed in an expanded structure by separating from the upper end region of the net body 200 to the outer edge. When a part of the input guide part 440 is formed by separating from the upper end region of the net body 200 to the outer edge, the object to be juiced input into the large diameter input port 410 is guided to the net body 200.

[0093] Meanwhile, the input guide unit 440 is a component that allows the object to be juiced, which is input into the large diameter input port 410 and not cut by the crushing unit 340, to be transferred to the net body 200 and the screw 300. That is, the input guide unit 440 is a component that naturally connects the large diameter input port 410 formed on the outer edge based on the screw rotation shaft 320 to the net body 200.

[0094] In addition, the input guide section 440 is formed overlapping with the large diameter input port 410, is continuously connected to the large diameter input port 410, and is formed inclined toward the screw rotation axis 320 so that the side of the object to be juiced begins to be crushed by the crushing section 340 or the spiral rib 310.

[0095] In addition, the end of the insertion guide portion 440 is formed in a stepped shape with the net body, and at this time, the end of the insertion guide portion 440 is formed to coincide with the inner side surface of the upper end of the net body 200.

[0096] The rotating shaft accommodating groove 450 is a predetermined groove formed so that the screw rotating shaft 320 formed on the upper side of the screw 300 can be inserted therein.

[0097] The crushing rib 460 is formed vertically on the inner surface of the hopper 430, and crushes the object of juice extraction by interacting with the screws 300a, 300b. The crushing rib is formed in a plurality of pieces. In addition, the crushing rib may be shaped to become narrower downward or wider downward.

[0098] FIG. 15 is a diagram showing a first state of use of the screw according to the second modified embodiment of the present invention.

[0099] FIG. 16 is a diagram showing a second state of use of the screw according to the second modified embodiment of the present invention.

[0100] Referring to FIG. 15, an object to be juiced, for example, a carrot, is placed on a support surface 350 formed on the upper side of the screw, and then cut by one rotation of the screw 300b.

[0101] 16, the object to be squeezed, for example, celery, is placed on a support surface 350 formed on the upper side of the screw, and then, before being cut by the crushing unit 340, it inclines in contact with the upper flow stage 364 and lies on the crushing unit entrance stage 370. That is, the object to be squeezed, which has a long shape, is caught by the upper flow stage 364, and lies between the storage unit 360 and the crushing unit entrance stage 370, and is cut by the screw 300b rotating once.

[0102] The above description is merely an illustrative example of the technical concept of the present invention, and various modifications and variations are possible within the scope of the essential characteristics of the present invention, if one has ordinary knowledge in the technical field to which the present invention belongs. Therefore, the above embodiments are intended to explain the present invention, and are not intended to limit the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by the above embodiments.
