Description

Detachable pulp discharge device for juicers

[0001] The present invention relates to a detachable pulp discharge device for a juicer, and more specifically, to a detachable pulp discharge device for a juicer in which a juice packing disposed in a pulp discharge port to provide resistance to pulp discharge can be easily detached.

[0002] Recently, as interest in health has increased at home, the use of juicers that allow individuals to make and consume juice directly from ingredients such as vegetables, grains, and fruits is on the rise.

[0003] Generally, as disclosed in Korean Registered Patent No. 793852, a juicer operates by pressing the juice material onto a grater, utilizing the principle of grinding soybeans with a millstone to extract the juice.

[0004] To this end, the juicer is equipped with a drive unit that provides rotational force, a drum housing including a drive shaft that receives rotational force from the drive unit, a screw that is connected to the drive shaft and uses a screw spiral formed in a part thereof to compress and crush the juice material, and a juice drum that separates the juice produced by the screw.

[0005] The drive unit of the juicer consists of a motor and a reduction gear, and the motor transmits rotational force to the screw through the drive shaft. In this case, the drive shaft passes through the lower part of the drum housing and is connected to the screw.

[0006] The pulp separated from the juice inside the drum housing is discharged to the outside through the pulp discharge port at the bottom of the drum housing and the pulp discharge pipe connected thereto. However, small particles of pulp adhere to the juicing drum and the pulp discharge port, remaining as residue; if this pulp is not completely removed after juicing is complete, there is a risk of bacterial proliferation, which may lead to hygiene problems.

[0007] In order to facilitate the smooth discharge of waste, the waste outlet is equipped with a packing made of a material such as rubber, which provides discharge resistance to the discharge of waste through the waste outlet, but this causes a problem where waste gets stuck between the outlet and the packing, making cleaning difficult.

[0008] In particular, simple cleaning is possible by filling the drum housing with water and rotating the screw while the juice outlet is closed, and the residue inside the residue outlet can also be wiped away using a thin brush. However, residue stuck between the residue outlet and the packing is not easily removed, and there is a problem in that the juicing parts must be completely disassembled and cleaned to remove the residue stuck between the residue outlet and the packing.

[0009] Accordingly, the objective of the present invention is to solve such conventional problems by providing a detachable pulp discharge device for a juicer that allows the extraction packing placed in the pulp discharge port to be easily detached in order to provide resistance to pulp discharge.

[0010] In addition, the invention provides a detachable pulp discharge device for a juicer that can adjust the discharge resistance of the juiced pulp from the juice packing according to the type of juiced material or the user's preference.

[0011] The above objective is achieved by a detachable pulp discharge device for a juicer according to the present invention, comprising: a pulp discharge port formed in the drum housing to discharge the pulp within the drum housing; a pulp discharge pipe provided in the drum housing to communicate with the pulp discharge port to discharge the pulp discharged through the pulp discharge port to the outside; a packing bar detachably coupled to the pulp discharge pipe; and a juice packing fixed to the packing bar and applying discharge resistance to the pulp discharged from the discharge port while the packing bar is coupled to the pulp discharge pipe.

[0012] Here, it is preferable that the juicing packing includes a packing portion interposed between the packing bar and the inner surface of the residue discharge pipe, and a resistance portion extending from the packing portion and positioned at a location corresponding to the residue discharge port to apply discharge resistance to the juicing residue.

[0013] In addition, it is preferable that a mounting groove is formed in the lower part of the packing portion, and a mounting projection corresponding to the mounting groove is formed on the upper surface of the packing bar.

[0014] In addition, a fixing projection is formed on the lower surface of the packing bar, and it is preferable that the juicing packing includes a connecting ring that can be coupled to the fixing projection on the lower surface of the packing bar.

[0015] In addition, it is preferable that a packing catch is formed on the upper surface of the packing bar to support the lower edge of one end of the packing portion to which the resistance portion is extended.

[0016] In addition, it is preferable that the resistance portion be extended upwardly from one side of the packing portion.

[0017] In addition, it is preferable that the inner lower bottom surface of the above-mentioned sludge discharge pipe be positioned with a downward slope.

[0018] In addition, it is preferable that a plurality of comb-like grooves are formed on the inner surface of the above-mentioned waste discharge pipe, extending toward the direction of waste discharge.

[0019] In addition, it is preferable that a plurality of comb-like grooves are formed on the upper surface of the packing bar, extending toward the direction of waste discharge.

[0020] In addition, it is preferable that the above-mentioned waste discharge pipe includes a first fixing part for fixing the position of the packing bar.

[0021] In addition, it is preferable that the packing bar includes a second fixing part that can engage with the first fixing part at the connection position to the waste discharge pipe.

[0022] In addition, it is preferable that the second fixing part of the packing bar is selectively coupled to any one of the plurality of first fixing parts.

[0023] In addition, it is preferable that the second fixing part has an inclined surface formed on one side toward the first fixing part.

[0024] In addition, the above packing bars are provided in multiple quantities, and each packing bar is coupled with a juicing packing having a different discharge resistance applied to the juice residue, and it is preferable to select one of the multiple packing bars and connect it to the residue discharge pipe to adjust the discharge resistance of the juice residue.

[0025] In addition, it is preferable that the juice extraction packings each coupled to the plurality of packing bars have different materials or shapes.

[0026] In addition, the drum housing further includes a juice storage section in which juice generated by pressing and crushing the material is collected, and an auxiliary discharge hole connecting the juice storage section and the inside of the residue discharge pipe, wherein the auxiliary discharge hole is preferably positioned so that it can be closed by the juice extraction packing at the connection position of the packing bar.

[0027] In addition, it is preferable that a protruding ring portion capable of closely adhering to the area around the auxiliary discharge hole is formed at a position corresponding to the auxiliary discharge hole on the outer surface of the above-mentioned juice packing.

[0028] According to the present invention, a detachable pulp discharge device for a juicer is provided, which allows a juice packing disposed in a pulp discharge port to be easily detached to provide pulp discharge resistance, thereby facilitating cleaning of the inside of the drum housing.

[0029] In addition, a detachable pulp discharge device for a juicer is provided that allows the discharge resistance of the pulp provided through the extraction packing to be adjusted according to the type of extraction material or the user's preference, which has the effect of greatly improving user convenience.

[0043] Hereinafter, a detachable residue discharge device for a juicer provided in a drum housing (10) according to one embodiment of the present invention will be described with reference to the drawings.

[0045] A detachable pulp discharge device for a juicer according to one embodiment of the present invention includes a pulp discharge port (110), a pulp discharge pipe (120), a packing bar (130), and a juice packing (140), as shown in FIG. 2.

[0046] A residue discharge port (110) is formed on the bottom surface of the drum housing (10) to discharge the juice residue within the drum housing (10). According to an embodiment of the present invention, the residue discharge port (110) may be formed to communicate in the vertical direction on the bottom surface of the drum housing (10). The bottom surface of the drum housing (10) refers to a disc-shaped structure formed on the lower part of the drum housing (10) to support the first screw (20) and the juice drum (30). A hole through which the shaft of the motor passes may be formed in the center of the bottom surface. The juice residue is discharged through the residue discharge port (110) by being pushed by the screw spiral of the rotating first screw (20).

[0047] A residue discharge pipe (120) is provided on the outer side of the drum housing (10) to communicate with the residue discharge port (110) in order to discharge the juice residue discharged through the residue discharge port (110) to the outside of the drum housing (10). That is, the juice residue is separated from the juice within the drum housing (10) and discharged to the outside by sequentially passing through the residue discharge port (110) and the residue discharge pipe (120). The inner lower bottom surface of the residue discharge pipe (120) is positioned at a downward slope from a position corresponding to the residue discharge port (110) to facilitate the smooth discharge of the juice residue, and as shown in FIG. 3, a plurality of comb grooves (122) are formed extending in the direction of residue discharge on the inner lower bottom surface.

[0048] The juice residue is discharged through the residue discharge port (110) in a form with minimal moisture and slides along the inclined inner lower bottom surface of the residue discharge pipe (120) to be discharged to the outside. At this time, as the juice residue slides along the inclined inner lower bottom surface of the residue discharge pipe (120), the contact area with the juice residue can be minimized by the comb groove (122) formed on the inner lower bottom surface, thereby minimizing contact friction and inducing smooth discharge of the juice residue.

[0049] Additionally, a first fixing part (121) is formed in the waste discharge pipe (120) to fix the coupling position of the packing bar (130). For example, the first fixing part (121) may be formed in the form of a coupling groove that is recessed from the inner surface of the waste discharge pipe (120). The first fixing part (121) may be formed on the inner lower bottom surface near the opening of the waste discharge pipe (120) through which the juiced waste is discharged.

[0050] The packing bar (130) is formed in the shape of a rod that can be detachably coupled inside the waste discharge pipe (120), and the coupling position to the waste discharge pipe (120) is set so that the juice packing (140) coupled to the packing bar (130) can provide discharge resistance to the juiced waste discharged through the waste discharge port (110).

[0051] In an embodiment of the present invention, the packing bar (130) is formed as a bar in a generally flat shape according to the shape of the inner lower bottom surface of the square-shaped waste discharge pipe (120), but if the waste discharge pipe (120) is formed in the shape of a cylindrical pipe, it may be formed as a bar in a generally semi-cylindrical shape with the upper end cut off to correspond to the inner lower bottom surface of the cylindrical shape.

[0052] On the upper surface of one end of the packing bar (130) inserted into the interior of the waste discharge pipe (120), a mounting projection (131) is formed so that the juice extraction packing (140) can be attached, and on the lower surface of one end, a fixing projection (132) is formed so that the connecting ring (144) of the juice extraction packing (140) can be fixed.

[0053] A second fixing part (133) capable of engaging with the first fixing part (121) is formed on the lower surface of the other end of the packing bar (130) that is exposed to the outside of the waste discharge pipe (120). For example, the second fixing part (133) may be formed in the form of a coupling projection protruding from the bottom surface of the packing bar (130). The front surface of the second fixing part (133) facing the first fixing part (121) may be formed as an inclined surface so that coupling with the first fixing part (121) can be achieved during the process of inserting the packing bar (130) into the waste discharge pipe (120). A lever (134) is formed on the other end of the packing bar (130) so that the second fixing part (133) can be moved in a direction to separate it from the first fixing part (121).

[0054] Meanwhile, the above-mentioned juice packing (140) is elastically compressed by being pressed by the packing bar (130) while the packing bar (130) is coupled within the waste discharge pipe (120). Since the elastic restoring force of this juice packing (140) acts in a direction in which the coupling surfaces of the first fixing part (121) and the second fixing part (133) come into close contact, the coupling between the first fixing part (121) and the second fixing part (133) can be prevented from being arbitrarily released.

[0055] Additionally, the packing bar (130) is connected to the waste discharge pipe (120) while being supported on the inner lower bottom surface of the waste discharge pipe (120), and in the connected state, it is positioned at a downward slope corresponding to the slope of the inner lower bottom surface of the waste discharge pipe (120), and a plurality of comb grooves (136) are formed on the upper surface extending toward the direction of waste discharge.

[0056] Additionally, as shown in FIGS. 4 and 5, a support member (135) may be formed protruding from the lower surface between the end portion and the central portion of the packing bar (130) that is inserted into the waste discharge pipe (120), so as to be supported on the lower inner surface of the waste discharge pipe (120). That is, when the packing bar (130) is fixed inside the waste discharge pipe (120), the support member (135) and the second fixing portion (133) are supported on the lower inner surface of the waste discharge pipe (120), and at this time, the end portion of the packing bar (130) may be lifted upward. Accordingly, the juice extraction packing (140) positioned on the upper side of one end of the packing bar (130) can be pressed toward the bottom surface of the drum housing (10) located on the upper side of the waste discharge pipe (120) while the packing bar (130) is connected to the waste discharge pipe (120).

[0057] Additionally, a packing catch (137) may be formed at a position corresponding to the waste discharge port (110) on the upper surface of one end of the packing bar (130). The packing catch (137) may be formed in a shape that can stably support the lower edge of one end of the packing part (141) which is fixed to the mounting projection (131) of the packing bar (130).

[0058] The juice packing (140) can be coupled to one end of the packing bar (130) and can be placed in close contact with the lower side of the waste outlet (110) to apply discharge resistance to the juiced waste discharged through the waste outlet (110). In addition, the juice packing (140) can be made of an elastic material to provide a space where the juiced waste can be discharged while applying a certain resistance to the juiced waste discharged from the waste outlet (110).

[0059] Specifically, the juice extraction packing (140) includes a packing portion (141) interposed between the packing bar (130) and the inner surface of the waste discharge pipe (120), a resistance portion (143) extending from one side of the packing portion (141) toward the other end of the packing bar (130) and positioned at a location corresponding to the waste discharge port (110) to apply discharge resistance to the juice extraction waste, and a connecting ring (144) extending from the other side of the packing portion (141) and capable of being coupled to a fixing projection (132) on the lower surface of the packing bar (130).

[0060] A mounting groove (142) is formed in the lower part of the packing portion (141) to be coupled with a mounting projection (131) formed on the upper surface of one end of the packing bar (130).

[0061] As shown in FIG. 6, the packing bar (130) is connected to the waste discharge pipe (120) by inserting one end, to which the juice packing (140) is fixed, through the opening of the waste discharge pipe (120), and then, as shown in FIG. 7, connecting the second fixing part (133) formed at the other end of the packing bar (130) to the first fixing part (121) formed on the inner bottom surface of the waste discharge pipe (120). In this process, the packing part (141) of the juice packing (140) enters the inner end region of the waste discharge pipe (120) and can be interposed between the packing bar (130) and the inner surface of the waste discharge pipe (120) in an elastically compressed state.

[0062] The resistance part (143) closes the residue discharge port (110) and extends in the direction in which the juice residue reaching the juice packing (140) is discharged, that is, toward the other end of the packing bar (130), thereby providing discharge resistance to the juice residue.

[0063] The lower edge of one end of the packing portion (141) is stably supported by the packing catch (137) of the packing bar (130). Therefore, it is possible to prevent the resistance portion (143) extending from the one end of the packing portion (141) from being excessively deformed in the downward direction due to the residue discharge pressure.

[0064] The resistance portion (143) can be formed to be inclined toward the bottom surface of the drum housing (10), that is, upward. By doing so, the resistance portion (143) can be in close contact with the bottom surface of the drum housing (10) and apply sufficient discharge resistance to the juiced residue discharged from the residue discharge port (110), thereby allowing the moisture of the juiced residue to be removed as much as possible. Meanwhile, as shown in FIG. 6, when the juiced packing (140) is separated from the residue discharge pipe (120) together with the packing bar (130), the resistance portion (143) is inclined upward; however, as shown in FIG. 2, when the juiced packing (140) is mounted on the residue discharge pipe (120) together with the packing bar (130), the resistance portion (143) can be in close contact with the bottom surface of the drum housing (10) and have a shape that is generally parallel to the bottom surface.

[0065] The connecting link (144) may be made of the same material as the juice packing (140), and may also be made of wire or the like. That is, the juice packing (140) can be maintained connected to the packing bar (130) through the connecting link (144) as shown in Fig. 5 (b). Therefore, even when the juice packing (140) is separated from the packing bar (130) for complete cleaning of the juice packing (140), that is, when the mounting projection (131) of the packing bar (130) is separated from the mounting groove (142) of the juice packing (140), the juice packing (140) and the packing bar (130) remain connected, so the loss of the juice packing (140) can be prevented.

[0066] FIG. 8 is a drawing illustrating a usage state in which juice residue is discharged from a drum housing according to one embodiment of the present invention.

[0067] Referring to FIG. 8, a first screw (20) and a juicing drum (30) are arranged in the internal space of the drum housing (10), and the first screw (20) receives driving force and rotates around a longitudinal rotation axis. When a user inserts material into the space between the first screw (20) and the juicing drum (30) from the top, the material moves downward along the screw spiral (22) of the rotating first screw (20) and is compressed or crushed by the first screw (20) and the juicing drum (30). At this time, the juice moves into the internal space of the first screw (20) through the juice discharge hole formed in the first screw (20), is collected in the juice storage section (150) between the first screw (20) and the drum housing (10), and then moves to the juice discharge port (not shown) provided on the outside of the drum housing (10), and the juice residue is pushed by the screw spiral (22) and moves to the lower part of the drum housing (10), and then moves toward the residue discharge port (110) formed on the bottom surface of the drum housing (10). The juice residue moved toward the residue discharge port (110) receives discharge resistance from the juice packing (140) blocking the residue discharge port (110), and thereby the juice residue undergoes a process of being compressed once more. Accordingly, the discharge pressure of the juice residue increases, causing the juice residue to push the juice packing (140) out of the residue discharge port (110) and move into the space between the residue discharge port (110) and the juice packing (140). After that, the juice residue is discharged to the outside of the drum housing (10) through the residue discharge pipe (120).

[0068] As illustrated in FIG. 8, the packing bar (130) has a juice packing (140) fixed at one end and positioned at the inner end of the waste discharge pipe (120). A support member (135) protruding from the lower surface of one end of the packing bar (130) is supported on the inner lower bottom surface of the waste discharge pipe (120), and a second fixing part (133) at the other end is engaged with the first fixing part (121) of the waste discharge pipe (120) to fix the connection position.

[0069] At this time, the juice packing (140) fixed to one end of the packing bar (130) is pressed upward by the principle of a lever centered on the support (135), so the sealing force for the waste discharge port (110) and auxiliary discharge hole (151) can be improved.

[0070] Specifically, the packing portion (141) of the juice extraction packing (140) is pressed by the packing bar (130) and elastically compressed within the end portion of the waste discharge pipe (120) to seal the auxiliary discharge hole (151) of the juice storage portion (150). Thus, it is possible to prevent the juice collected in the juice storage portion (150) from flowing out toward the waste discharge pipe (120) through the auxiliary discharge hole (151).

[0071] Additionally, the resistance portion (143) extending in one direction from one side of the packing portion (141) is elastically supported in an upward direction to close the residue discharge port (110) below the bottom surface of the drum housing (10), and is opened while elastically deforming in a downward direction due to the discharge pressure of the juice residue, thereby providing discharge resistance against the discharge of the juice residue.

[0072] When ingredients are juiced using a juicer, the juice is discharged through the juice outlet, and the juice residue is discharged through the residue outlet (110). In this way, after using the juicer, the juice outlet is closed and the juice packing (140) is not removed. Then, a simple cleaning is possible by filling the drum housing (10) with cleaning water and rotating the first screw (20). That is, the juice residue and juice residue present inside can be simply cleaned without separating the juice drum (30) and the first screw (20) assembled in the drum housing (10).

[0073]

[0074] The detachable pulp discharge device for a juicer of the present embodiment may further include a juice storage section (150) in which juice generated by pressing and crushing a material between the first screw (20) and the juice drum (30) can be collected, and an auxiliary discharge hole (151) connecting the juice storage section (150) and the inside of the pulp discharge pipe (120).

[0075] The juice storage section (150) is provided as a concave space in which juice extracted during the process of pressing and grinding materials and moved into the internal space of the first screw (20) through the juice discharge hole formed in the first screw (20) can be collected, and is formed on the upper side of the bottom surface of the drum housing (10) which is formed in a disc shape. The juice collected in the juice storage section (150) can be discharged to the outside through a separate juice discharge port provided on the outside of the drum housing (10). The juice storage section (150) can be separated from the waste discharge area where the waste discharge port (110) is formed by a ring-shaped rib of a predetermined height disposed on the bottom surface of the drum housing (10). That is, the juice storage section (150) can be formed as a ring-shaped area disposed on the inside of the ring-shaped rib, and the waste discharge area can be formed as a ring-shaped area disposed on the outside of the ring-shaped rib.

[0076] The auxiliary discharge hole (151) is formed through the bottom surface of the drum housing (10) at a location where the internal space of the juice storage section (150) and the waste discharge pipe (120) overlap, and connects the inside of the juice storage section (150) and the waste discharge pipe (120). This auxiliary discharge hole (151) can be sealed by the juice extraction packing (140) while the packing bar (130) is coupled inside the waste discharge pipe (120), so that the juice stored in the juice storage section (150) does not leak out toward the waste discharge pipe (120), and can be opened while the juice extraction packing (140) is separated from the waste discharge pipe (120) together with the packing bar (130), so that the washing water stored inside the juice storage section (150) can be discharged toward the waste discharge pipe (120).

[0077] The auxiliary discharge hole (151) can be sealed by the juice extraction packing (140). To this end, the auxiliary discharge hole (151) can be positioned radially from the center of the bottom surface of the drum housing (10) along the same axis as the waste discharge port (110). Additionally, the end portion of the internal space of the waste discharge pipe (120) can be extended to the lower region of the juice storage portion (150). That is, the packing portion (141) of the juice extraction packing (140) is fixed in a position that is elastically compressed within the end portion of the internal space of the waste discharge pipe (120) while the packing bar (130) is coupled within the waste discharge pipe (120). At this time, the upper surface of the packing portion (141) can be in close contact with the bottom surface of the drum housing (10) where the auxiliary discharge hole (151) is formed, thereby closing the auxiliary discharge hole (151). In this state, the resistance portion (143) extending from the packing portion (141) can close the residue discharge port (110) to provide discharge resistance to the juice residue discharged through the residue discharge port (110).

[0078] Meanwhile, a protruding ring portion capable of adhering closely to the area around the auxiliary discharge hole (151) is formed at a position corresponding to the auxiliary discharge hole (151) on the outer surface of the packing portion (141), thereby further improving the sealing power of the packing portion (141) for the auxiliary discharge hole (151). Accordingly, the juice stored in the juice storage portion (150) can be effectively prevented from flowing out toward the waste discharge pipe (120) through the contact surface between the packing portion (141) that seals the auxiliary discharge hole (151) and the drum housing (10).

[0079]

[0080] From now on, the process of separating the first embodiment of the detachable pulp discharge device for the juicer described above from the drum housing will be explained.

[0081] FIGS. 9 and FIGS. 10 are cross-sectional views showing the process of separating the packing bar (130) of the detachable residue discharge device for the juicer of the present invention.

[0082] As illustrated in FIG. 9, the packing bar (130) undergoes a process of separating from the waste discharge pipe (120) by lifting the lever (134) upward and moving the packing bar (130) outward as illustrated in FIG. 10. That is, when the packing bar (130) holding the juice packing (140) is separated from the waste discharge pipe (120), the waste discharge port (110) and auxiliary discharge hole (151), which were sealed by the juice packing (140), are opened, and the cleaning water inside the drum housing (10) can be discharged to the outside of the drum housing (10) through the waste discharge pipe (120).

[0083] To explain in more detail, when the packing bar (130) is to be separated, as shown in FIG. 9, if the lever (134) formed at the other end of the packing bar (130) is lifted upward, the second fixing part (133) formed on the lower surface of the other end of the packing bar (130) is detached from the first fixing part (121) formed on the inner lower bottom surface of the waste discharge pipe (120). At the same time, as the packing bar (130) rotates around the support (135) in contact with the inner lower bottom surface of the waste discharge pipe (120), the end part fixing the juice packing (140) moves downward, thereby releasing the pressure that presses the juice packing (140) upward.

[0084] As described above, when the second fixing part (133) is detached from the first fixing part (121) and the pressure applied to the juice packing (140) is released, it is possible to pull out the packing bar (130) from the waste discharge pipe (120) as shown in FIG. 10.

[0085] At this time, since the extraction packing (140) that seals the waste discharge port (110) and the auxiliary discharge hole (151) can be separated from the drum housing (10), the problem of waste getting stuck between the conventional waste discharge port (110) and the extraction packing (140) and making cleaning difficult can be solved. In addition, as the cleaning water inside the drum housing (10) is discharged through the auxiliary discharge hole (151) as well as the waste discharge port (110), the flow rate of the cleaning water discharged into the waste discharge pipe (120) increases, so the waste remaining inside the waste discharge pipe (120) can also be easily removed.

[0086] According to the above embodiment, the juice residue and juice residue remaining inside the drum housing (10) can be sufficiently removed with only simple washing, thereby improving the convenience of using the juicer.

[0087]

[0088] Next, various modifications for attaching and detaching the packing bar according to the present invention will be described.

[0089] FIGS. 12 to 16 are drawings showing various variations of the packing bar detachable structure according to the present invention.

[0090] As illustrated in FIG. 12, the first modified example for attaching and detaching the packing bar (130) according to the present invention has a difference in configuration from the first embodiment described above in that a plurality of first fixing parts (121') formed on the inner lower bottom surface of the waste discharge pipe (120) are provided and spaced apart from each other along the longitudinal direction of the waste discharge pipe (120).

[0091] According to this configuration, a second fixing part (133) formed on the lower surface of the other end of the packing bar (130) can be selectively coupled to any one of the plurality of first fixing parts (121'), thereby enabling adjustment of the coupling position of the packing bar (130) to the waste discharge pipe (120).

[0092] It is preferable that the plurality of first fixing parts (121') be formed so as to be able to adjust the coupling position of the packing bar (130) within a range in which the juice packing (140) can seal the waste discharge port (110) and the auxiliary discharge hole (151).

[0093] The first fixing part (121') and the second fixing part (133) can be formed in the shape of a coupling groove and a coupling projection, similar to the first embodiment.

[0094] The resistance portion (143) of the juice extraction packing (140) is configured such that one end is fixed to the packing portion (141) while positioned horizontally, and provides discharge resistance to the juice residue discharged through the upper residue discharge port (110).

[0095] At this time, since the discharge pressure of the juice residue for the resistance part (143) changes in proportion to the gap between the end of the packing part (141) of the resistance part (143) and the residue discharge port (110), it is possible to adjust the magnitude of the discharge resistance of the resistance part (143) for the juice residue by changing the coupling position of the packing bar (130) as described above.

[0096] Specifically, as shown in FIG. 12 (a), one end of the packing bar (130) to which the juice extraction packing (140) is fixed is inserted into the interior of the waste discharge pipe (120), and then the assembly position can be fixed by connecting the second fixing part (133) formed on the lower side of the other end of the packing bar (130) to the first fixing part (121') formed on the outermost of the plurality of first fixing parts (121'). At this time, the juice extraction packing (140) fixed to one end of the packing bar (130) has the packing part (141) side end of the resistance part (143) positioned close to the waste discharge port (110), so the discharge resistance of the resistance part (143) against the juice extraction waste can be increased.

[0097] Conversely, as shown in FIG. 12 (b), when the assembly position of the packing bar (130) is fixed by connecting the second fixing part (133) of the packing bar (130) to the innermost first fixing part (121') among the plurality of first fixing parts (121') provided in the waste discharge pipe (120), the extraction packing (140) fixed to one end of the packing bar (130) has the packing part (141) side end of the resistance part (143) spaced apart from the waste discharge port (110), so the discharge resistance of the resistance part (143) to the extraction waste can be lowered.

[0098] As illustrated in FIG. 13, a second modified example for attaching and detaching a packing bar (130) according to the present invention has a difference in configuration from the first embodiment described above in that a first fixing part (121a) is formed on both sides in contact with the internal space of the waste discharge pipe (120) and a second fixing part (133') that can be coupled to the first fixing part (121a) is formed on both sides of the other end of the packing bar (130).

[0099] The first fixing part (121a) may be formed in the shape of a coupling groove, and the second fixing part (133') may be formed in the shape of a coupling projection that can be seated and supported within the coupling groove.

[0100] According to this configuration, the connection position of the packing bar (130) to the waste discharge pipe (120) can be fixed by inserting the juice extraction packing (140), which is connected to one end of the packing bar (130), into the waste discharge pipe (120) and then seating the second fixing part (133'), which is formed on both sides of the other end of the packing bar (130), onto the first fixing part (121a), which is formed on both sides of the opening of the waste discharge pipe (120). Here, it is preferable that the connection position of the first fixing part (121a) and the second fixing part (133') be set to a position where the juice extraction packing (140), which is connected to one end of the packing bar (130), can close the auxiliary discharge hole (151) and the waste discharge port (110) of the drum housing (10).

[0101] As illustrated in FIG. 14, the third variant for attaching and detaching the packing bar (130) according to the present invention differs in configuration from the second variant described above in that a plurality of first fixing parts (121b) are spaced apart along the longitudinal direction, i.e., the length direction of the waste discharge pipe (120), on both sides that contact the internal space of the waste discharge pipe (120).

[0102] According to this configuration, a second fixing part (133') formed on both sides of the other end of the packing bar (130) can be selectively coupled to any one of a plurality of first fixing parts (121b) formed in multiple stages on the waste discharge pipe (120), thereby allowing the coupling position of the packing bar (130) to the waste discharge pipe (120) to be adjusted forward and backward.

[0103] Here, the plurality of first fixing parts (121b) are formed so that the front and rear positions of the juice packing (140) can be adjusted within a range in which the juice packing (140) can seal the waste discharge port (110) and the auxiliary discharge hole (151).

[0104] That is, when the second fixing part (133') of the packing bar (130) is fixed to the innermost first fixing part (121b) among the plurality of first fixing parts (121b), the elastic deformation reference point of the resistance part (143) (the connection part between the resistance part (143) and the packing part (141)) is positioned close to the residue discharge port (110) to increase the discharge resistance for the extracted residue, and when the second fixing part (133') of the packing bar (130) is fixed to the outermost first fixing part (121b) among the plurality of first fixing parts (121b), the elastic deformation reference point of the resistance part (143) is positioned apart from the residue discharge port (110) to decrease the discharge resistance for the extracted residue.

[0105] In addition, as illustrated in FIG. 15, the fourth variant for attaching and detaching the packing bar (130) according to the present invention has a difference in configuration from the third variant described above in that a plurality of first fixing parts (121c) are spaced apart in the vertical direction on both sides in contact with the internal space of the waste discharge pipe (120) to form multiple stages, and each first fixing part (121c) is open toward the end surface of the opening side of the waste discharge pipe (120).

[0106] That is, the second fixing part (133') formed on both sides of the other end of the packing bar (130) can be coupled to any one of the plurality of first fixing parts (121c) formed on both sides of the waste discharge pipe (120), and accordingly, the angle of the packing bar (130) can be adjusted.

[0107] Accordingly, as shown in FIG. 16 (a), when the second fixing part (133') of the packing bar (130) is coupled to the second fixing part (121c) located at the bottom, the angle between the packing bar (130) and the resistance part (143) becomes relatively larger, and thus the amount of elastic deformation of the resistance part (143) sealing the lower part of the residue discharge port (110) is reduced, thereby reducing the discharge resistance for the juice residue.

[0108] Conversely, as shown in FIG. 16 (b), when the second fixing part (133') of the packing bar (130) is coupled to the second fixing part (121c) located at the top, the angle between the packing bar (130) and the resistance part (143) becomes relatively smaller, and thus the amount of elastic deformation of the resistance part (143) sealing the lower part of the residue discharge port (110) increases, thereby increasing the discharge resistance for the juice residue.

[0109] Meanwhile, although not shown in the drawing, it is also possible to provide a plurality of packing bars (130) each having a different extraction packing (140) that provides different discharge resistance to the extraction residue, and to select one of the packing bars (130) that has a extraction packing (140) that can provide suitable discharge resistance according to the usage environment or material and to configure it to be coupled within the residue discharge pipe (120).

[0110] At this time, each juice packing (140) may have a different material or shape to adjust the discharge resistance value. For example, each juice packing (140) may be formed of a different material having a different elastic modulus or set to have a different thickness of resistance portion (143).

[0111] Although the detachable pulp discharge device for a juicer according to the present embodiment has been described as being applied to a juicer of the first embodiment in which a first screw (20) and a juice drum (30) are disposed inside a drum housing, it is not limited to this juicer method and can be applied to various juicers having a juicer method different from this juicer method.

[0112] For example, the detachable pulp discharge device for a juicer according to the present invention can also be applied to a juicer in which a second screw (20'), a mesh drum (30'), and a rotating brush (40) are arranged inside a drum housing (10), as shown in FIGS. 17 and 18.

[0113] In this case, the juice material introduced into the boundary between the second screw (20') and the mesh drum (30') can be compressed and crushed during the process of being conveyed downward by the rotation of the second screw (20'), and the juice extracted during this process can be discharged to the area outside the mesh drum (30') through the mesh body (32) formed in the mesh drum (30'). The juice discharged to the area outside the mesh drum (30') can be discharged to the outside through the juice discharge pipe (11) formed in the housing body (10).

[0114] The rotating brush (40) rotates between the housing body (10) and the mesh drum (30') and sweeps the inner surface of the side wall of the housing body (10) and the outer surface of the mesh drum (30') to continuously remove juice or juice residue. During the juicing process of the material, the juice residue separated from the juice is pushed downward by the screw spiral (22) inside the mesh drum (30'), passes through the residue discharge hole at the bottom of the mesh drum (30'), and then can be discharged through the residue discharge port (110) formed on the bottom surface of the housing body (10).

[0115] Meanwhile, in order to transmit the rotational power of the second screw (20') to the rotating brush (40), a first gear (21) is formed on the lower outer surface of the second screw (20'), a second gear (41) is formed on the lower inner surface of the rotating brush (40), and a connecting gear (50) can be disposed between the first gear (21) and the second gear (31) in the drum housing (10).

[0116] As the configuration in which discharge resistance is provided by the resistance part (143) of the extraction packing (140) during the process in which the extraction residue is discharged through the residue discharge port (110), the detachable structure of the packing bar (130), and the configuration in which the discharge resistance for the extraction residue is controlled by adjusting the coupling position of the packing bar (130) have been described above, a detailed description thereof is omitted.
