Description

A JUICE SQUEEZING DRUM}

The present invention relates to a juice drum, and more particularly, to a juice drum capable of stably driving a power transmission shaft inserted therein without deterioration and having an interlocking gear interlocked with a brush, .

In recent years, interest in health has increased in households, and the frequency of use of an electric juice dispenser having an ability to take juice from vegetables such as vegetables, grains, fruits, and the like is increased.

A typical mode of operation of such a juicer is a method of squeezing juice by pressing the input material as disclosed in Korean Patent No. 0793852.

To this end, the juicer includes a driving shaft for providing a rotational force, and a juice drum for receiving a rotational force from the driving shaft to perform a function of pressing the juice object.

The gastric juice drum is provided with a screw which is connected to the drive shaft and presses and crushes the juice object by a screw spiral formed in a part of the screw, and a net drum which separates the juice made by the screw.

On the other hand, Korean Patent No. 0755440 discloses a juicer having a brush for sweeping the inner wall of the juice drum and the outer wall of the net drum. That is, the intermediate gear is fixed to the bottom surface of the juice drum so as to be gear-engaged with the drive shaft, and the intermediate gear receives the driving force from the power transmission shaft to rotate the upper brush.

However, according to the above-mentioned Patent No. 0755440, since the intermediate gear is fixed to the bottom surface of the juice drum so as to receive the driving force from the drive shaft, it is not easy to clean the intermediate gear. Since the brush is gear-connected to the intermediate gear, juice or debris flowing down the outer wall of the net drum disposed inside the brush can be introduced into the intermediate gear. Further, juice or debris adhering to the intermediate gear may interfere with transmission of the driving force between the intermediate gear and the brush, and may cause hygienic problems.

In addition, if the user wishes to directly clean the upper middle gear, it is necessary to grasp the juice drum in one hand and wipe the intermediate gear inside the upper juice drum with the other hand, which is inconvenient. Moreover, since the upper intermediate gear must be cleaned without disassembly from the juice drum, it is difficult to completely clean the inside of the intermediate gear.

On the other hand, the other prior art juicer is configured to transmit the rotational force to the intermediate gear via a power transmitting shaft between a driving shaft constituted by a motor or the like and an intermediate gear. However, in order to transmit the rotational force stably to the screw and the intermediate gear for squeezing or crushing the juice object, the power transmission shaft must always be aligned in the axial direction. That is, the drive shaft and the power transmission shaft must be kept perpendicular to the bottom of the juicer while maintaining their coaxiality with each other.

According to the prior art, in the case of the juice drum in which the drive shaft is disposed at the lower part, a considerable load is applied to the power transmission shaft engaged with the drive shaft, and the structural rigidity is weakened. Further, the vibration of the drive shaft is transmitted to the power transmission shaft as it is, and the power transmission shaft may be detached from the shaft direction or may be slightly shaken.

First of all, if the screw is tilted from the axis of the power transmission shaft by a small line, the screw will vibrate in the horizontal direction, so that the screw will vibrate more horizontally than the lower part. It is important to do. It is also important to keep the screw from moving in the vertical direction when the screw is fitted in the power transmission shaft.

An object of the present invention is to provide a juice drum which is easy to clean by providing an interlocking gear for transferring the rotational force of the power transmission shaft to the juice drum.

It is another object of the present invention to provide a juice drum which is driven more stably by attaching a bushing to the outside of the power transmission shaft.

According to an aspect of the present invention, there is provided a juice drum including: a screw that rotates upon receiving a driving force from a power transmission shaft; A net drum provided outside the radius of the screw and discharging juice or pulverized water; A screw housing having the screw and the mesh drum inside thereof, the upper surface of the screw housing being formed in an opened pillar shape; A protruding portion protruding upward from a bottom surface of the juice housing and configured to surround the power transmission shaft inserted therein; And an inner surface of the bushing enclosing the outer circumferential surface of the power transmitting shaft to support the power transmitting shaft and an outer surface of the bushing having a shape corresponding to the inner surface of the protruding portion.

Wherein a sealing groove is formed radially inwardly of the outer circumferential surface of the power transmission shaft and the sealing groove is provided with a sealing member for sealing between the power transmission shaft and the protrusion, And an outer end thereof is inclined to the upper side of the protrusion.

The protruding portion may be formed such that its upper edge is curved, and its outer circumferential surface extends obliquely downward.

According to another aspect of the present invention, there is provided a juice drum comprising a juice housing, a screw built in the juice housing and rotated by receiving a driving force from a power transmission shaft, and a screw provided outside the radius of the screw, A brush disposed between the mesh drum and the juice housing and connected to the power transmission shaft for sweeping the outer circumferential surface of the mesh drum and / or the inner circumferential surface of the juice housing while rotating, And a power transmission module for transmitting rotational force to the brush. The power transmission module includes a driving gear mounted on a side end or a lower end of the power transmission shaft and rotating together with the power transmission shaft, and an intermediate gear that receives rotational force from the driving gear and transmits the rotational force to the brush, And the driving gear and the brush are selectively gear-connected to each other.

The juice drum may further include at least one interlocking gear disposed between the driving gear and the intermediate gear and transmitting the rotational force of the driving gear to the intermediate gear.

When the intermediate gear is inserted and connected to the interlock gear, the lower end of the intermediate gear further projects downward from the lower surface of the interlock gear so that the intermediate gear can be easily separated.

A gear upper portion formed on an upper end of the intermediate gear and disposed on an upper surface of the juice housing to transmit rotational force to the brush; A gear center portion extending axially downward from an upper portion of the gear and penetrating the juice housing; And a gear lower portion extending obliquely downward from the middle portion of the gear and having a polygonal cross-section so as to be selectively connected to the interlocking gear.

The present invention may further include a packing which closely contacts the outer circumferential surface of the center portion of the gear and the outer surface of the packing closely contacts the juice housing to block the infusion of the juice or the pulverized material into the inside of the intermediate gear.

And a packing groove recessed radially inwardly is formed on an outer circumferential surface of the gear middle portion, and the packing is inserted into the packing groove.

A gear upper portion formed on an upper end of the intermediate gear and disposed on an upper surface of the juice housing to transmit rotational force to the brush; A gear center portion extending axially downward from an upper portion of the gear and penetrating the juice housing; And a gear lower portion extending downward from the middle of the gear and selectively connected to the interlock gear; Wherein the lower parts of the gears are spaced from each other and extend axially downward so as to face each other; Wherein the intermediate gear is detachable from the interlocking gear by pressing the pair of assembling legs in directions opposite to each other.

Wherein the intermediate gear further includes a pressing protrusion protruded outward from a lower end of the pair of the assembling legs, and in a state in which the intermediate gear is inserted into the interlocking hole formed inside the interlocking gear, And is supported at the lower end of the interlocking gear to restrict axial movement of the intermediate gear.

The present invention further includes a packing which is mounted on a packing groove formed in the middle of the gear and whose outer side is in close contact with the bottom surface of the juice housing to prevent the juice or pulverized product from flowing into the interlocking gear side And the packing may be formed so as to be inclined outwardly of the center of the gear and downward in the axial direction.

According to the embodiment of the present invention as described above, the intermediate gear can be attached and detached from the juice drum as required, so that the intermediate gear can be easily cleaned, and the juice drum can be sanitarily managed. In addition, since the juice or debris adhered to the intermediate gear can be completely removed, malfunction of the intermediate gear can be cut off during the power transmission process, and the rotational force transmitted to the intermediate gear can be completely transmitted to the brush.

Further, by mounting the bushing so as to support the power transmission shaft outside the power transmission shaft, the power transmission shaft can always be aligned in the axial direction, so that vibration or fine vibration generated in the power transmission shaft can be significantly blocked. Further, by reinforcing the lower end of the power transmission shaft in which a strong load is generated, its durability can also be improved. Further, as the power transmission shaft rotates stably, the expected performance of the screw and the brush that receives the driving force from the power transmission shaft can be satisfied.

1 to 3 illustrate one of various kinds of juice drums for the convenience of explanation, and the technical idea of the present invention is not limited to the juice drums exemplified in this specification, Type juice drums.

1 to 3, a juice drum 1 according to an embodiment of the present invention includes a juice housing 10, a hopper 20, a gear cover 30, a power transmission shaft 40, a screw 50, A net drum 60, a brush 70, and a power transmission module 200.

The juice housing 10 is formed in a columnar shape with its upper surface opened and includes a side wall 10a and a bottom surface 10b constituting outer and lower surfaces thereof.

A juice outlet 11 and a juice outlet 13 may be formed at the lower end of the side wall 10a of the juice housing 10. The juice outlet 11 and the sludge outlet 13 are spaced from each other in the circumferential direction. The passageway that is moved to the juice outlet 11 and the passageway that is moved to the dirt outlet 13 are separated from each other with reference to the network drum 60.

The juice outlet (11) is configured to discharge the juice flowing out from the vents (not shown) of the net drum (60). At this time, the lower surface of the juice outlet (11) is formed to be inclined toward the outside of the radius of the juice housing (10) and the direction of the paper, so that juice can be easily discharged. The opening of the juice outlet 11 may be provided with an opening / closing means 12, and the amount of the juice discharged through the opening / closing means 12 may be adjusted.

The debris discharge port 13 may be formed in a rectangular or cylindrical column shape having a generally open front face and the debris delivered to the lower side of the mesh drum 60 is pushed out to the debris discharge port 13. Meanwhile, the residue is transferred to the residue discharge port 13 through the residue discharge hole 13a (see FIG. 12) formed on the bottom surface 10b of the juice housing 10, and the area of the residue discharge hole 13a is adjusted And an adjusting lever 14 for adjusting the amount of the discharged debris.

According to the embodiment of the present invention, the waste outlet 13 is formed in the side wall 10a of the juice housing 10, but the present invention is not limited thereto. The waste outlet 13 may be formed on the bottom surface 10b of the juice housing 10 ), It is possible to smoothly discharge the residue.

Further, although not shown in the drawing, a collection cup for collecting juice or debris may be provided on the lower side of the juice discharge port 11 and the residue discharge port 13, respectively.

A hopper 20 is detachably mounted on the side wall 10a of the juice housing 10. The hopper 20 is adapted to cover the open upper portion of the juice housing 10, and the lower portion thereof is formed in a shape corresponding to the upper surface of the juice housing 10. The hopper 20 comprises a first disk 21 preferably having a side surface, a neck 23 for guiding the introduced material to the juice housing 10 and a second disk 25 covering the top of the juice housing 10, .

The first disc 21 is formed in a disc shape, and a material inlet 22 is formed on one side of the upper surface of the first disc 21 so that the material can be inserted into the first disc 21. The material inlet 22 is formed at a distance from the center of the first disk 21, i.e., at a position eccentric from the power transmission shaft 40 of the juice drum 1. [ Therefore, even if the screw 50 rotates, it is possible to insert the material smoothly. The side portion formed at the edge of the first disc 21 extends upward in the height direction to prevent the material from escaping.

The neck portion 23 is formed so as to be relatively long in the vertical direction and substantially perpendicular to the paper surface so as to guide the material introduced into the material inlet 22. However, the present invention is not limited to this, and the neck portion 23 may be inclined so that the material may smoothly slide into the juice housing 10. The neck 23 is narrow and long inside so that the hand can not enter deeply.

Further, the second disk 25 is configured to have a shape corresponding to the open top of the juice housing 10 so as to cover the upper part of the juice housing 10. The second disk 25 guides the materials introduced from the neck 23 into the juice housing 10.

The bottom surface 10b of the juice housing 10 will be described with reference to Figs. 4 and 5. Fig.

4, a protrusion 15 is integrally formed with the juice housing 10 at a central portion of the bottom surface 10b of the juice housing 10. The protruding portion 15 can be formed in a columnar shape, and protrudes upward from the bottom surface 10b in the axial direction. The projecting portion 15 can be formed in a generally cylindrical shape with its upper edge curved, and its outer peripheral surface extends obliquely downward from the upper edge. The screw 50 has an inner surface that is the same as or similar to the outer surface of the protrusion 15 so as to accommodate the protrusion 15 and the inner surface of the screw 50 is concavely curved upward. At least the lower end edge of the projecting portion 15 is formed in a shape substantially corresponding to the lower end of the screw 50, so that the inner side portion of the screw 50 can be supported. The projection 15 is configured to be received in a space formed by the curved inner surface of the screw 50. [ However, the protrusion 15 is not limited to the upper shape, but may be formed in a half sphere shape which is convex upward.

An insertion hole 17 is formed in the radial direction of the protrusion 15. The power transmission shaft 40 penetrates through the insertion hole 17 to transmit the driving force to the screw 50.

The upper projecting portion 15 is formed so as to protrude upward and the outer side surface thereof is formed close to the inner side surface of the screw 50 so that juice or debris flows into the space between the projecting portion 15 and the power transmission shaft 40 prevent. The protruding portion 15 is formed in a curved shape at its upper edge so that even if juice or debris flows into the protruding portion 15, the protruding portion 15 flows down to the bottom surface 10b again and is discharged to the residue outlet 13 .

At the edge of the bottom surface 10b of the juice housing 10, there is formed a gear insertion hole 209 into which a gear assembly 210 to be described later is inserted. A packing support body 250 is mounted inside the radius of the gear insertion hole 209. The packing 260 can be seated on the upper side of the packing support 250.

Referring to FIG. 5, a plurality of assembly projections 16 protruding radially inward are formed along the circumferential direction on the lower surface of the protruding portion 15. The assembling protrusion 16 is inserted and fixed in an assembling groove 125 (see FIG. 8) of the bushing 100 mounted on the inside of the protrusion 15, and can prevent the bushing 100 from rotating in the circumferential direction. Further, the assembling protrusions 16 and the bushing 100 can be firmly fixed to each other by bolts 111 or screws.

A fixing protrusion 12a protruding downward may be formed at a lower portion of the bottom surface 10b of the juice housing 10 so as to be spaced apart in the circumferential direction and the fixing protrusion 12a is fixed to a fixing hole 32a.

A gear fixing portion 202a for rotatably fixing a first interlocking gear 202, which will be described later, protrudes downward at a position spaced apart from the center of the bottom surface 10b of the juice housing 10 by a predetermined distance, . The gear fixing portion 202a has an outer circumferential surface formed in an uneven columnar shape, and the interlocking gear 202 is inserted and mounted. For example, a plurality of convex portions 202b may be formed on the outer circumferential surface of the gear fixing portion 202a.

A gear insertion hole 209 (see FIG. 14) is located outside the radius of the upper gear fixing portion 202a, and a part of the packing support 250 mounted inside the radius of the gear insertion hole 209 protrudes downward have.

6, the gear cover 30 is formed in a shape corresponding to the lower face of the upper juice housing 10, and is coupled to the lower portion of the upper juice housing 10. As shown in FIG. The gear cover 30 is provided with a gear seating portion 31, a gear guide portion 33, and a drive gear support portion 35.

The gear seating portion 31 supports the lower axial end of the gear assembly 210 and allows the gear assembly 210 to rotate stably. Particularly, the interlock gear 230, which is disposed between the juice housing 10 and the gear cover 30 and transmits rotational force to the gear assembly 210, can be fixed.

The gear guide portion 33 protrudes upward from the upper surface of the gear cover 30 and extends in the radial direction along both sides of the power transmission module 200 so that external foreign matter penetrates into the power transmission module 200 While minimizing power loss due to external aerodynamic forces.

The driving gear support portion 35 protrudes upward in a circular ring shape and is inserted into a groove formed in the lower surface of the driving gear 41 rotating together with the power transmission shaft 40. Thus, the power transmission shaft 40 is prevented from moving in the radial direction, and at the same time, the driving gear 41 can be stably rotated along the circumferential direction.

Referring to FIG. 7, the power transmission shaft 40 is a component that receives rotational force from a drive shaft (not shown) that provides a rotational force. A driving hole 43 having a polygonal shape is formed on the lower surface of the power transmitting shaft 40. The driving shaft 43 is inserted into the driving hole 43 so that the power transmitting shaft 40 can be rotated. It is needless to say that the drive shaft must be formed in the same polygonal shape as the polygonal shape of the drive hole 43 to transmit the rotational force.

The power transmitting shaft 40 extends in the axial direction, and the upper end thereof is formed into a polygonal columnar shape. The upper end of the power transmission shaft 40 passes through the insertion hole 17 of the projection 15 and is connected to the screw shaft 53 to rotate the screw 50. Needless to say, the inner surface of the screw shaft 53 must have the same polygonal shape as the upper portion of the power transmission shaft 40 in order to receive rotational force.

A cylindrical body 45 is formed at an axially intermediate portion of the power transmitting shaft 40 and a bushing 100 to be described later is coupled to the outer peripheral surface of the body 45.

A drive gear 41 is formed at the lower end of the power transmission shaft 40. The drive gear 41 is formed in a disk shape and mounted on the outer circumferential surface of the power transmission shaft 40 to rotate together with the power transmission shaft 40. A tooth and a groove are alternately disposed on the outer circumferential surface or the lower surface of the driving gear 41. [ Accordingly, the driving gear 41 can rotate and transmit the rotational force of the power transmitting shaft 40 to the brush 70. [

On the upper side of the body portion 45 of the power transmission shaft 40, a sealing groove 46 is formed along the circumferential direction in the radial direction (see Fig. 2). A sealing member 49 is mounted on the sealing groove 46 and is stably fixed by the sealing groove 46.

The sealing member 49 may be formed of a material such as rubber or silicon. The inner end of the sealing member 49 is attached to the sealing groove 46 of the upper body 45 and the outer end of the sealing member 49 is in contact with the outer surface of the projection 15. [ 2, the outer end of the sealing member 49 is inclined downward toward the outer side in the radial direction so that juice or water is introduced between the body portion 45 of the power transmission shaft 40 and the protruding portion 15 Is more effectively blocked.

That is, the sealing member 49 may be formed in the shape of a ring and extends so as to have a slope radially outward from the upper side to the lower side. As a result, juice or debris naturally falls down to the bottom surface 10b along the outer surface of the projecting portion 15 on the outer peripheral surface of the upper sealing member 49. [

According to the embodiment of the present invention, the juice drum 1 may be further provided with a bushing 100 to support the body 45 and the lower end of the power transmission shaft 40. The upper bushing 100 will be described in more detail with reference to Figs. 8 to 9. Fig.

8 to 9, the bushing 100 includes a bushing flange 110 and a bushing reinforcement 120. As shown in Figs. A mounting hole 103 is formed at the center of the bushing flange 110 and the bushing reinforcing portion 120 and the power transmission shaft 40 is inserted through the mounting hole 103. The bushing flange 110 and the bushing reinforcement 120 may be integrally formed.

The lower surface of the bushing flange 110 is formed in a shape corresponding to the upper surface of the driving gear 41, and a plurality of screw holes 115 are formed along the circumferential direction.

The bushing reinforcement portion 120 extends upward from the upper surface of the upper bushing flange 110 and is formed in a shape in which its upper edge is curved so as to correspond to the inner surface of the projecting portion 15. [ Therefore, the boding reinforcement 120 can be inserted and mounted into the space formed inside the projection 15.

A plurality of mounting grooves 125 are formed in the bushing reinforcing portion 120 along the circumferential direction. The mounting grooves 125 are preferably formed at positions corresponding to the screw holes 115. The assembly groove 125 is configured to receive the assembling protrusion 16 formed inside the upper projecting portion 15 as described above. When the bolt 111 is fastened to the screw hole 115 in the upward direction with the assembling protrusion 16 engaged with the assembling recess 125, the bushing 100 is mounted on the protrusion 15 of the juice housing 10 , And can be fixed.

The upper bushing 100 is configured to surround the outside of the power transmitting shaft 40 and can firmly fix the power transmitting shaft 40 and the juice housing 10 in the axial direction. Accordingly, the vibration or fine vibration generated in the power transmitting shaft 40 can be significantly blocked, and the power transmitting shaft 40 is always kept aligned in the axial direction. Furthermore, the structural rigidity of the juice drum 1 itself can be enhanced by reinforcing the lower end of the power transmission shaft 40, which is relatively strongly loaded, with the upper bushing 100.

1 to 3, the screw 50 receives rotational force from the power transmitting shaft 40 and rotates, and performs a function of pressing or crushing the juice object. To this end, the screw 50 is provided with a screw shaft 53, which is connected to the power transmission shaft 40.

A plurality of screw spirals 51 are formed in the screw 50 at a portion contacting the mesh drum 60. The juice is squeezed by the narrow gap between the screw (50) and the net drum (60) by the screw thread (51), and is conveyed to the lower side.

The mesh drum 60 may be formed with a plurality of mesh holes on its side so that the juice generated by the screw 50 can be discharged outside the mesh drum 60. The net drum 60 is fixed to the juice drum 1 and is not rotated. The debris in the mesh drum 60 is pushed downward and discharged through the debris discharge port 13, and the juice having passed through the vesicles can be discharged through the juice discharge port 11. [

In this case, the mesh drum 60 and the screw 50 are used to crush and crush the juice object, but the juice and the residue And all of the pulverized material is discharged through the residue discharge port 13 without being separated. The crushing net drums can be used to add iced fruit, chocolate, ice cream, ice, dairy products, drinks and other materials together to obtain plants such as ice cream, smoothies and sherbet.

The brush 70 is disposed between the juice housing 10 and the net drum 60 and connected to the power transmission shaft 40 to rotate. The brush (70) includes a brush holder (71) and a brush blade (73).

The brush holder 71 includes an upper ring 71a, a lower ring 71b, and a connecting post 72. The upper ring 71a and the lower ring 71b have a circular ring shape and the radius of the upper ring 71a is formed larger than the radius of the lower ring 71b. A brush gear 75 may be provided on the side or bottom of the lower ring 71b to transmit the rotational force from the power transmission shaft 40 to the brush 70. [

The connecting pillars 72 are integrally formed with the upper ring 71a and the lower ring 71b, and are connected to each other, and a plurality of connecting pillars 72 are formed along the circumferential direction. A predetermined space S is formed between the connecting pillars 72, so that the brush holder 71 can be made lighter.

The connecting pillar 72 is mounted with a brush blade 73 protruding radially inward or outward. Brush wings 73 mounted radially inwardly or radially outward of the connecting posts 72 sweep the radially outer side of the mesh drum 60 or the radially inner side of the juice housing 10 when the brush 70 is rotated So that the juice adsorbed on the mesh drum 60 and / or the juice housing 10 is smoothly wiped off to the bottom surface 10b.

The brush blade 73 is made of a soft silicone material, so that the mesh drum 60 or the juice housing 10 can be smoothly swept away.

In addition, when the user intends to clean the inside of the juice drum 1, the user can put the cleaning liquid or water into the juice drum 1, and operate the brush 70. At this time, the brush 70 can completely remove juice or debris adhered to the mesh drum 60 or the juice housing 10.

According to the embodiment of the present invention, in order to transmit rotational force from the power transmitting shaft 40 to the brush 70, a power transmitting module 200 is provided. The power transmission module 200 will be described in more detail with reference to FIGS. 10 to 12. FIG.

10 to 11, the power transmitting module 200 of the juice drum 1 according to the embodiment of the present invention includes a driving gear 41, a gear assembly (210). Further, a plurality of gears may be provided between the drive gear 41 and the gear assembly 210. For example, first and second interlock gears 202 and 230 may be interposed between the driving gear 41 and the gear assembly 210. [

The drive gear 41 is attached to the lower end of the power transmission shaft 40 and rotates together with the power transmission shaft 40, as described above. The driving gear 41 meshes with the first interlocking gear 202 and transmits the rotational force to the second interlocking gear 230.

The first interlocking gear 202 is mounted on the bottom surface of the juice housing 10 and rotates in engagement with the driving gear 41.

A gear bearing 204 is inserted in the radial direction of the first interlocking gear 202. The radially inner surface of the gear bearing 204 is formed in a shape corresponding to the outer peripheral surface of the gear fixing portion 202a described above, and the radially outer surface of the gear bearing 204 is formed into a smooth cylindrical shape. Further, the gear bearing 204 is fixed by a bolt or a screw while being inserted into the gear fixing portion 202a.

Therefore, the gear bearing 204 is fixed in the circumferential direction or the axial direction by the gear fixing portion 202a, and the first interlocking gear 202 mounted outside the radius thereof is stably fixed along the outer peripheral surface of the gear bearing 204 It can rotate.

The second interlock gear 230 is rotatably disposed on the upper side of the seat 31 of the gear cover 30 and below the bottom surface of the juice housing 10. [ The second interlocking gear 230 is disposed radially outward of the first interlocking gear 202 and receives the rotational force from the first interlocking gear 202 and transmits the rotational force to the gear assembly 210.

As described above, by disposing the first and second interlock gears 202 and 230 between the radial directions of the drive gear 41 and the gear assembly 210, the intermediate gears of the gear assembly 210 220 may be located at the radially outer edge of the bottom surface 10b of the juice housing 10. [ Therefore, a space for the lower portion of the screw 50 can be ensured, and the degree of freedom in designing the space can be improved.

In the above embodiment, the power transmission module 200 of the juice drum 1 is configured as a combination of a plurality of spur gears, but the present invention is not limited thereto. The gears of the power transmission module 200 may be configured in various forms, for example, bevel gears, screw gears, and worm gears.

The gear assembly 210 receives the rotational force from the first interlock gear 202 via the second interlock gear 230 and transfers the rotational force to the brush 70. To this end, the upper end of the gear assembly 210 is circumscribed or inscribed with the brush gear 75 formed on the upper brush 70. Of course, in this gear combination, the number of revolutions of the gears can be adjusted by adjusting the gear ratio. That is, unlike the rotation speed of the power transmission shaft 40, the brush 70 may be provided with a proper rotation speed depending on the juice object.

The configuration of the gear assembly 210 will be described in more detail with reference to FIGS. 13 to 14. FIG.

The gear assembly 210 includes an intermediate gear 220, a packing support 250, and a packing 260.

The upper end of the intermediate gear 220 is directly engaged with the brush gear 75 and receives the rotational force from the second interlock gear 230 provided at the lower end thereof to transfer the rotational force to the brush gear 75.

According to the embodiment of the present invention, the intermediate gear 220 can be selectively gear-coupled to the second interlock gear 230 fixed to the juice housing 10. [ That is, the user inserts the intermediate gear 220 into the gear insertion hole 209 formed at the edge of the bottom surface 10b of the juice housing 10 so as to gear the intermediate gear 220 to the second interlock gear 230 . The user can also detach the intermediate gear 220 geared with the second interlock gear 230 from the juice housing 10.

The intermediate gear 220 includes a gear upper portion 225 formed at its upper end to be engaged with the brush gear 75, a gear middle portion 240 extending axially downward from the center of the gear upper portion 225, And a gear lower portion 247 which extends further downward in the axial direction from the gear portion 240 and is inserted into the second interlock gear 230.

The gear upper portion 225 is disposed on the upper side of the bottom surface 10b of the juice housing 10 and directly gears with the brush gear 75 to transmit the rotational force to the brush gear 75. [

The gear middle portion 240 extends axially downward from the gear upper portion 225 and is formed into a cylindrical shape. The middle gear portion 240 is positioned in the gear insertion hole 209 of the bottom surface 10b with the intermediate gear 220 mounted on the juice housing 10. [ At this time, a ring-shaped packing support 250 is fixedly mounted inside the radius of the gear insertion hole 209, so that the outer peripheral surface 245 of the gear middle portion 240 is opposed to the inner peripheral surface of the packing support 250.

14, the outer circumferential surface 245 of the gear middle portion 240 is spaced apart at small intervals to form a receiving space O between the packing support 250 and the outer circumferential surface 245 of the gear middle portion 240. [ Due to this structure, interference by the packing support 250 is minimized when the intermediate gear 220 rotates.

The outer circumferential surface 245 of the gear middle portion 240 may be equipped with a packing 260 to be described later. Given that the packing 260 is made of a material such as rubber or silicone, the gear middle portion 240 may be made of a metal material to improve adhesion with the packing 260 made of the above material.

The gear lower portion 247 has a polygonal cross-section and is inserted into a radius of the second interlock gear 230 to rotate together with the second interlock gear 230.

The lower end of the gear lower portion 247 is formed in a tapered shape that tapers downward inward as it goes downward. Due to such a shape, when the intermediate gear 220 is inserted into the second interlock gear 230, the lower gear 247 can naturally engage with the second interlock gear 230. The thickness t (see Fig. 14) of the gear lower portion 247 is set to be equal to or slightly smaller than the outer circumferential surface of the accommodation space O formed inside the radius of the packing support 250. Accordingly, the intermediate gear 220 is inserted into the upper accommodation space O and can be engaged with the second interlock gear 230. [

The packing support 250 is formed in a generally columnar shape and fixed to the juice housing 10. The radially extending portion 251 and the axially extending portion 253 are formed in the packing support 250.

The radial extension 251 is formed to protrude radially outward from the side of the packing support 250 and can be inserted and fixed in a groove formed in the side wall 10a or the bottom surface 10b of the juice housing 10 have.

The axially extending portion 253 protrudes upward from the upper end of the packing support 250 and extends in the circumferential direction. The axially extending portion 253 is spaced apart from the juice housing 10 by a predetermined distance in the radial direction, and the outer circumferential surface of the axially extending portion 253 is in close contact with the packing 260 while wrapping it.

The packing 260 is generally formed in the shape of a ring, and is made of a material such as rubber or silicone which has both a sealing property and a constant elasticity. The inner circumferential surface of the packing 260 is in close contact with the outer circumferential surface 245 of the gear middle portion 240 of the intermediate gear 220 and the outer circumferential surface thereof is in close contact with the juice housing 10. At this time, a part of the packing 260 is brought into close contact with the upper part of the packing support 250 so that juice or pulverized material flows into the space between the intermediate gear 220, the packing support 250 and the gear insertion hole 209 .

The packing 260 includes a first packing disc 261 and a first packing ring 263, a second packing disc 265 and a second packing ring 267.

One end of the first packing disk 261 is in close contact with the outer circumferential surface 245 of the gear middle portion 240, and the other end thereof extends radially outward. The first packing disc 261 is spaced apart from the lower surface of the gear upper portion 225 by a predetermined space in the axial direction.

The first packing ring 263 extends axially upward from the radially outer end of the first packing disc 261 and the upper end thereof is in close contact with the lower surface of the gear upper portion 225.

The intermediate gear 220, the first packing disc 261 and the first packing ring 263 form a packing space P (see Fig. 14). This packing space P minimizes the contact between the packing 260 and the intermediate gear 220 and improves the drag torque.

The second packing disc 265 extends radially outward from the upper end of the first packing ring 263 so that the second packing disc 265 is spaced finely from the lower surface of the gear upper portion 225, (220) smoothly rotates.

The second packing ring 267 extends axially downward from the radially outer end of the first packing disk 265. The inner circumferential surface of the second packing ring 267 contacts the packing support 250 and the outer circumferential surface thereof is in close contact with the juice housing 10 .

By forming the first and second packing disks 261 and 265 and the first and second packing rings 263 and 267 in a labyrinth shape in this manner, The drag torque of the intermediate gear 220 can be improved.

Further, since the material of the packing 260 has elasticity, when the packing 260 is inserted into the gear insertion hole 209, a part of the packing 260 is pressed outside the radius. At this time, the inner surface of the packing 260 can completely block the inflow of the juice or the pulverized product inside the juice housing 10 by pressing the packing support 250 located inside thereof.

A gear assembly according to another embodiment of the present invention will be described with reference to Fig.

The gear assembly according to another embodiment of this month has the same or similar configuration as the packing support 250 and the packing 260 according to the embodiment of the present invention described above. Hereinafter, the intermediate gear 310 will be described in detail.

15, an intermediate gear 310 according to another embodiment of the present invention includes a gear upper portion 325 formed at its upper end with gear teeth to be engaged with a brush gear 75, And a gear lower portion 347 which extends further axially downward from the upper gear middle portion 340 and is inserted and coupled into the second interlock gear 230. The gear middle portion 340 extends in the downward direction.

The gear upper portion 325 is mounted on the upper surface of the juice housing 10 and gears to the brush gear 75 to transmit rotational force.

The gear middle portion 340 extends axially downward from the gear upper portion 325 and is formed in a generally cylindrical shape. As described above, since the gear middle portion 340 is made of a metal material, adhesion with the packing 260 mounted on the outer circumferential surface thereof can be improved.

On the outer circumferential surface of the gear middle portion 340, a packing groove 345 is formed along the circumferential direction so as to have a radially inward fins. The upper and lower ends of the packing 360 are supported by the packing grooves 345 so that the fitting between the packing 360 and the gear middle portion 340 can be enhanced.

The upper end 345a of the packing groove 345 is horizontally formed so as to be stepped in the radial direction and the lower end of the packing groove 345 is formed with an inclined surface 345b outwardly of the radius and axially downward. Therefore, the packing 360 can be inserted and fixed without hitting the packing groove 345 formed in the gear middle portion 340 from the gear lower portion 347 by the upper inclined surface 345b.

The gear lower portion 347 is formed in a polygonal cross-section and extends axially downward from the gear middle portion 340. At this time, the outer peripheral surface of the gear lower portion 347 is formed into a tapered shape radially inward, and is inserted into the second interlock gear 230 so as to be engaged with the second interlock gear 230.

16 is a perspective view showing the removal and attachment of the intermediate gear of the juice drum. As described above, the intermediate gears 220 and 310 can be selectively attached to and detached from the juice housing 10. As a result, juice, debris, and the like adhering to the intermediate gear 220 can be removed, and the juice drum 1 can be sanitarily managed.

The lower end of the gear assembly 210 further protrudes downward from the lower surface of the second interlock gear 230 when the intermediate gear 220 is mounted on the juice housing 10. [ Accordingly, when the lower end of the upper projecting gear assembly 210 is pushed upward, the gear upper portion 225 of the intermediate gear 220 is moved upward from the bottom surface of the juice housing 10, 225, and 325 project upward from the bottom surface of the juice housing 10. Then, the user can easily separate the intermediate gear 220 from the juice housing 10 by grasping and lifting up the gears 225 and 325.

17 to 18, the gear assembly 410 according to yet another embodiment of the present invention includes the intermediate gear 420 and the packing 460. As shown in FIG.

The intermediate gear 420 includes a gear upper portion 425 formed in a gear shape so as to engage with the brush gear 75 at the upper end thereof, a gear central portion 440 extending axially downward from the central portion of the gear upper portion 425, And a gear lower portion 450 further extended downward from the gear middle portion 440 and inserted into the second interlock gear 430.

The gear top 425 is spaced apart from the bottom surface of the juice housing 10 and a partition wall 411 is formed on the bottom surface of the juice housing 10 so that the juice or crushed material does not flow into the gear top 425 And is protruded upward in the axial direction.

The gear center portion 440 extends axially downward from the gear upper portion 425 and is formed into a generally cylindrical shape. At the upper end of the gear center portion 440, a packing groove 445 having a radius inward is formed so that the packing 460 is mounted. In addition, the center portion 440 of the gear can be made of a metal material, and the adhesion with the packing 460 mounted on the outer peripheral surface of the gear 440 can be improved.

The gear lower portion 450 has a generally rectangular cross-section, and its edge is curved. The gear lower portion 450 is inserted inside the radius of the second interlock gear 430 and can rotate together with the second interlock gear 430.

In the gear lower portion 450, a pair of assembly legs 453 are spaced apart from each other and extend axially downward, and the pair of assembly legs 453 are arranged to face each other. The pair of assembling legs 453 is inserted into the interlocking hole 435 formed inside the second interlocking gear 430 to connect the lower gear 450 to the second interlocking gear 430. The interlocking hole 435 may be formed in a rectangular shape whose edges are curved so as to correspond to the outer surface of the gear lower portion 450. A pushing protrusion 455 protruding radially outward is formed at a lower end of the pair of assembly legs 453.

The intermediate gear 420 is assembled as follows in the second interlock gear 430 and rotates together with the second interlock gear 430.

When the intermediate gear 420 is inserted into the interlocking hole 435 formed inside the second interlocking gear 430, the pair of assembling legs 453 are pressed in the radially inward direction, that is, The distance between them is reduced. 18, when the pair of assembling legs 453 is completely inserted into the interlocking hole 435, the pair of assembling legs 453 are moved in the radially outward direction, that is, opposite to each other in the opposing direction Direction and is restored. In other words, the pair of assembling legs 453 of the gear assembly 410 are elastically deformed and mounted in the upper interlocking hole 435. At this time, the pressing protrusion 455 supports the lower end of the second interlock gear 430 so as to prevent the axial shift of the intermediate gear 420.

When the upper gear assembly 410 is separated from the second interlock gear 430 and the juice housing 10, the pushing protrusions 455 are moved in the direction of the arrow shown in FIG. 18 (in the directions opposite to each other, And the lower end of the intermediate gear 420 is pushed upward. At this time, the pair of assembly legs 453 are deformed in the directions opposite to each other, and the intermediate gears 420 are lifted up from the bottom surface of the juice housing 10 at a predetermined interval axially upward, The intermediate gear 420 can be separated from the juice drum 1.

The packing 460 is formed generally in the shape of a ring, and is made of a material such as rubber or silicone that has both a sealing property and a constant elasticity. The inner circumferential surface of the packing 460 is in close contact with the packing groove 445 formed in the middle gear 440 of the intermediate gear 420 and the outer circumferential surface thereof is in close contact with the bottom surface of the juice housing 10. The packing 460 may extend obliquely from the outer circumferential surface of the intermediate gear 420 radially outwardly and axially downwardly. As a result, the juice or crushed water or the like can naturally fall along the outer surface of the packing 460 to the bottom surface of the juice housing 10.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Includes all changes to the scope permitted.
