[0054] In the following description, the term longitudinal direction is used to generally describe a direction toward a horizontal direction of FIG. 9, and width direction is used to generally describe a vertical direction of FIG. 9. Also, the term left is used to generally describe a direction facing a first support 230 in the horizontal direction of FIG. 9, and right is used to generally describe a direction facing a second support 250.

[0055] As illustrated in FIG. 9, a high-capacity juicing machine according to one embodiment of the present invention includes a base 210, a support member, a first juicing member 270, a second juicing member 290, an introducing unit 220, a discharge unit (not illustrated), a driving unit, and a collecting container 280. Parts of the above components are housed within a housing 200a.

[0056] The base 210 serves as a support of the high-capacity juicing machine 200. The base 210 is provided on an upper portion thereof with the support member, a first motor 241 and a second motor 261 for the driving unit, and the collecting container 280.

[0057] The support member has a first support 230 and a second support 250 which are spaced apart from each other on the base 210 in a longitudinal direction and are fixed thereto. Specifically, the first support 230 is installed to one side of the base, while the second support 250 is installed to the other side.

[0058] The first support 230 has a plurality of plate men ers which are connected to each other. The first support 230 rotatably supports a first support shaft 275 of the first juicing member 270 via a bearing which is installed in a hole penetrating the first support in the longitudinal direction. A first driving member 240 is interposed between the plate me ers of the first support 230.

[0059] The second support 250 has a plurality of plate members which are connected to each other. The second support 250 rotatably supports a second support shaft 293 of the second juicing member 290 via a bearing which is installed in a hole penetrating an upper portion of the second support in the longitudinal direction. A second driving member 260 is interposed between the plate members of the second support 250. The first support 230 and the second support 250 may be made of single plate member.

[0060] The second support 250 is provided with at least one support roller 251. The support roller 251 is rotatably installed to the second support 250 via a bearing. The support roller 251 is positioned below an opening of the first juicing member 270. The support roller 251 is spaced apart from the first juicing member 270 in a circumferential direction. The support roller 251 is to support the first juicing member 270.

[0061] As illustrated in FIGS. 9 to 11, the first juicing member 270 is rotatably engaged to the first support 230. The first juicing member 270 has an outer rotor 271, an inner screen 273, the first support shaft 275, and a reinforcing member 277.

[0062] The outer rotor 271 is interposed between the first support 230 and the second support 250. The outer rotor 271 has a first hollow cylindrical portion 2712 with a circular cross section, and a first disc 2714 which is formed in the shape of a circular plate and is engaged to a left end of the first cylindrical portion 2712. The outer rotor 271 is opened toward the second support.

[0063] An outer annular flange 2416 is engaged to the opened end of the first cylindrical portion 2712. The outer flange 2416 protrudes radially from the opened end of the first cylindrical portion 2712. And outer end face of the outer flange 2416 comes into contact with the support roller 251. The outer flange 2416 prevents extraction from leaking to the opened end of the first cylindrical portion 2712.

[0064] The first cylindrical portion 2712 of the outer rotor 271 is provided with a plurality of discharge holes 2711. The discharge holes 2711 are formed to radially penetrate a circumferential surface of the first cylindrical portion 2712. The discharge holes 2711 are spaced apart from each other in a longitudinal direction and a circumferential direction.

[0065] The first disc 2714 of the outer rotor 271 is provided with a first shaft opening 2717. The first shaft opening 2717 is positioned at the center of the first disc 2714, and penetrates the first disc in the longitudinal direction. The first support shaft 275 is inserted into the first shaft opening 2717.

[0066] The inner screen 273 is provided on the inner surface of the outer rotor 271. The inner screen 273 is fixed to the inner surface of the outer rotor 271 to rotate together with the outer rotor 271. The inner screen 273 is a mesh provided with a plurality of fine holes. The fine holes of the inner screen 273 are formed to be smaller than the size of the discharge holes 2711. The extraction is discharged through the fine holes, and the juiced residues are left in the inner screen 273.

[0067] The first support shaft 275 extends in the longitudinal direction. One end of the first support shaft 275 is rotatably supported by the first support 230 via a bearing, while the other end is inserted into the first shaft opening 2717 of the outer rotor 271., and is engaged to the first disc 2714. The first support shaft 275 is installed at the center of the first disc 2714, and is positioned in parallel with the first cylindrical portion 2712. Accordingly, the first support shaft 275 serves as a center axis of the outer rotor to become a center of rotation.

[0068] The right end of the first support shaft 275 is provided with an engaging portion 2751 extending outwardly in a radial direction. The engaging portion 2751 has an area larger than that of the first shaft opening 2717. The first support shaft 275 is not separated from the outer rotor 271 by the engaging portion 2751.

[0069] The reinforcing member 277 is formed in the shape of an annular plate. The reinforcing member 277 is positioned in such a way that the center of the reinforcing member coincides with the axis of the first support shaft 275. The first support shaft 275 penetrates the center of the reinforcing member 277. The reinforcing member 277 is fixed to the outer surface of the first disc 2714 by screws. The first support shaft 275 penetrating the reinforcing member 277 is fixed to the reinforcing member 277 by welding. The first support shaft 275 is fixed to the outer rotor 271 by the reinforcing member 277 to rotate together with the outer rotor 271.

[0070] As illustrated in FIGS. 12 and 13, the second juicing member 290 has an inner rotor 291, a second support shaft 293 and a fixing member 295.

[0071] The inner rotor 291 has a second hollow cylindrical portion 2912 with a circular cross section, and second discs 2914 which are provided to both sides of the second cylindrical portion 2912 and are formed in the shape of a circular plate. The inner rotor 291 has an outer diameter smaller than an inner diameter of the outer rotor 271 so that the inner rotor is positioned in the outer rotor 271. The inner rotor 291 is positioned in parallel with the outer rotor 271.

[0072] The second disc 2914 of the inner rotor 291 is spaced apart from an end of the second cylindrical portion 2912 in the longitudinal direction. The second cylindrical portion 2912 has a protrusion 2911 protruding outwardly from the second disc 2914 in the longitudinal direction. The protrusion 2911 protrudes over the end of the second support shaft 293 which is fastened to the second disc 2914, in the longitudinal direction, so that the protrusion comes into contact with the inside of the first disc 2714 of the outer rotor 271 or a small gap is formed between the protrusion and the first disc 2714. Accordingly, the extraction is easily guided to the small gap formed between the outer rotor 271 and the inner rotor 291 by the protrusion 2911, so that the juiced material is effectively extracted.

[0073] The inner rotor 291 is provided in the outer rotor 271 so that the inner rotor is eccentrical to the outer rotor 271 by the second support shaft 293 which is eccentrical to the first support shaft 275. The center of the inner rotor 291 is downwardly eccentrical to the center of the outer rotor 271.

[0074] The second cylindrical portion 2912 of the inner rotor 291 is provided with a plurality of bosses 2913. The bosses 2913 protrude outwardly from the outer peripheral surface of the second cylindrical portion 2912 in the radial direction. The bosses 2913 are spaced apart from each other in the longitudinal direction and the circumferential direction. Since sliding movement between the outer rotor 271 and the inner rotor 291 is prevented by the bosses 2913, the extraction is easily guided to the small gap between the outer rotor 271 and the inner rotor 291.

[0075] The second disc 2914 installed to the right end of the second cylindrical portion 2912 is provided with a through-hole 2915 at the center thereof. The second support shaft 293 which is the rotational shaft of the inner rotor 291 is inserted into the through-hole 2915.

[0076] The second disc 2914 installed to the left end of the second cylindrical portion 2912 is provided with a receiving hole 2917 at the center thereof which penetrates the second disc in the longitudinal direction. The receiving hole 2917 has a diameter smaller than that of the through-hole 2915. The second support shaft 293 which is the rotational shaft of the inner rotor 291 is inserted into the receiving hole 2917.

[0077] The second support shaft 293 extends in the longitudinal direction. One end of the second support shaft 293 is rotatably installed to the second support 250 via a bearing, while the other end is inserted into the receiving hole 2917 through the through-hole 2915, and then is engaged to the second disc 2914 of the inner rotor 291. The second support shaft 293 is fixed to the inner rotor 291, so that the inner rotor 291 is rotated integrally with the second support shaft 293.

[0078] The second support shaft 293 serves as a center shaft of the inner rotor 291, and thus becomes a center of rotation. The second support shaft 293 is downwardly eccentrical to the first support shaft 275, and is positioned in parallel with the first support shaft 275.

[0079] The left end of the second support shaft 293 is provided with an insertion portion 2931 having a stepped portion. The insertion portion 2931 has a diameter smaller than that of the right end of the second support shaft 293. The insertion portion 2931 is inserted into the receiving hole 2917 formed in the inner rotor 291, and then protrudes from the outer surface of the second disc 2914. The end of the insertion portion 2931 is positioned at a position inwardly away from the end of the protrusion 2911 in the longitudinal direction. The fixing member 295 is installed to the insertion portion 2931 protruding from the outer surface of the second disc 2914.

[0080] The fixing member 295 has a nut, and is fastened to a threaded portion which is formed on the outer peripheral surface of the insertion portion 2917. Therefore, the second support shaft 293 is prevented from being released from the inner rotor 291 in the longitudinal direction.

[0081] As illustrated in FIG. 9, the configuration of the introducing unit 220 and the discharge unit (not illustrated) is substantially identical to that of the juicing machine according to the related art, and thus the detailed description thereof will be omitted herein.

[0082] The collection container 280 is provided on the base 210. The collection container 280 is spaced apart from the first juicing member 270 in the width direction. The collection container 280 is a hollow body opened toward the first juicing member 270. The collection container 280 is formed to be larger than or equal to the longitudinal length of the first juicing member 270. The collection container 280 is able to come in or out from the opening formed in the housing 200a.

[0083] The driving unit has the first driving member 240 connected to the first support shaft 275, and the second driving member 260 connected to the second shaft 293.

[0084] The first driving member 240 is provided on the first support 230. The first driving member 240 has a first motor 241, pulleys and a belt. The first motor 241 is provided on the base 210, and is spaced apart from the first support shaft 275 in the width direction. The pulleys are fixed to the first motor 241 and the first support shaft 275.

[0085] The second driving member 260 is provided on the second support 250. The second driving member 260 is connected to the second support shaft 293 of the second juicing member 290, and has a second motor 261, pulleys and a belt. The second motor 261 is provided on the base 210, and is spaced apart from the second support shaft 293 in the width direction. The pulleys are fixed to the second motor 261 and the second support shaft 293.

[0086] As illustrated in FIG. 1.4, the first support shaft 275 and the second support shaft 293 are rotated by the driving unit to rotate the outer rotor 271 and the inner rotor 291.

[0087] The juiced material is introduced into the big gap formed between the outer rotor 271 and the inner rotor 291, and then is guided to the small gap by the gravity and the outer rotor 271 and the inner rotor 291 which rotated in a direction indicated by the arrow in FIG. 14, so that the juiced material is pressed and extracted between the inner surface of the outer rotor 271 and the outer surface of the inner rotor 291.

[0088] The first driving member 240 is connected to the first support shaft 275, and the second driving member 260 is connected to the second support shaft 293, so that a circumferential speed V1 of the outer rotor 271 is different from a circumferential speed V2 of the inner rotor 291. Since the circumferential speeds of the outer rotor 271 and the inner rotor 291 are different from each other, the juiced material is extracted while being rotated.

[0089] If the circumferential speed V1 of the outer rotor 271 is set to be faster than the circumferential speed V2 of the inner rotor 291, the juiced material is rotated in the same rotational direction as that of the outer rotor 271 and the inner rotor 291. If the circumferential speed V1 of the outer rotor 271 is set to be slower than the circumferential speed V2 of the inner rotor 291, the juiced material is rotated in a direction opposite to the rotational direction of the outer rotor 271 and the inner rotor 291. Accordingly, the juiced material is extracted while revolving and rotating, thereby improving juicing performance, as compared to the case where the juiced material is extracted at the same circumferential speed.

[0090] According to some tests, in case where the circumferential speed V2 of the inner rotor 291 is set to be fast, the juicing performance is further improved, as compared to the case where the circumferential speed V1 of the outer rotor 271 is set to be fast.

[0091] As illustrated in FIG. 15, the high-capacity juicing machine 200 further includes a control unit C connected to the first and second driving members 240 and 260, an input unit I connected to the control unit C to input a kind of juicing material, a storage unit S connected to the control unit C and stored by a rotational speed database, in which rotational speed values of the first and second support shafts 275 and 293 are predetermined according to the kind of the juiced material, and a display unit D connected to the control unit C to display the rotational speeds of the first and second support shafts 275 and 293.

[0092] The control unit C is connected to the first motor 241 of the first driving member 240 and the second motor 261 of the second driving member 260 to control the rotational speeds of the first and second support shafts 275 and 293.

[0093] The input unit I is provided to input the kind of juiced material or input the rotational speed values of the first and second support shafts 275 and 293.

[0094] According to the method of operating the control unit C, if the kind of juiced material is inputted by the input unit I, the rotational speed values of the first and second support shafts 275 and 293 are set from the rotational speed database stored in the storage unit S according to the inputted kind of juiced material. The control unit C controls the rotational speeds of the first and second support shafts 275 and 293 to operate the support shafts at the predetermined rotational speed values stored in the storage unit S.

[0095] The rotational speed values of the first and second support shafts 275 and 293 are directly inputted through the input unit I, and the control unit C controls the rotational speeds of the first and second support shafts 275 and 293 so that the first and second support shafts 275 and 293 are rotated at the inputted rotational speeds.

[0096] Accordingly, the control unit C controls the rotational speeds of the first and second support shafts 275 and 293 according to the kind of juiced material which is inputted through the input unit I, or controls the rotational speeds of the first and second support shafts 275 and 293 at the inputted rotational speed values of the first and second support shafts 275 and 293.

[0097] While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
