Description

Juicer including brush {Juicer including brush}

The present invention relates to a juicer including a brush for crushing and compressing vegetables or fruits to make green juice or juice or soy milk with soybeans, and more particularly, to show an excellent juice juice function regardless of the type of vegetables or fruits. While driving in an ultra-low speed rotation method and relates to a juicer comprising a brush that effectively discharges the juice and debris.

In many cases, making green juice or juice directly at home for a healthy life has been increasing, and for this purpose, many devices have been disclosed for making juices using vegetables or fruits at home.

In general, the juicer accommodates fruits or vegetables in a housing in which the grinding screw is rotatably mounted, and then rotates the grinding screw using a drive motor located at the bottom of the housing to squeeze and crush the fruits or vegetables to juice or juice. It is extracted to drink. Existing juicers may have the advantage that the pulverization is performed in a short time because the flesh is broken by the pulverizing screw driven at a high speed, but the fruit is inherently flavored and There is a problem that nutrients are destroyed.

Therefore, there is a limit to ingesting the inherent taste and influence of fresh beans or fruits in order to lead a healthy life.

In addition, the conventional soymilk maker rotates the rotating shaft to which the grinding screw is fastened through a driving motor, and breaks the soybeans into pieces by impact force with the grinding screw, or finely grinds the beans with the grinding screw. Because soy milk is made, there is a problem that the delicious taste and nutrition of soybeans are reduced due to frictional heat with the grinding screw blade.

Recently, in order to minimize the nutrient destruction of materials supplied by the conventional juicer or soymilk maker and to maintain a good taste, a reduction gear is connected to a driving motor that compresses and grinds the material to reduce the rotational speed and rotates. Consideration is given to increasing the torque.

On the other hand, when the rotation speed of the grinding screw is reduced by using a reduction device, the juice juice is slow to move to the juice outlet formed in the housing, and the thick viscous juice with high viscosity does not flow down well and is placed on the wall of the drum or the housing. Koi has its drawbacks.

Particularly, a mandrel guide jaw for guiding the mandrel in which the grinding screw is accommodated is formed at the inner center of the housing, and the mandrel guide jaw has a problem of preventing smooth movement of the juice extracted in the housing. That is, the extraction of the juice is not easy due to the height of the mandrel guide jaw in the juice is discharged to the outside of the housing.

Then, the juicer is used to couple the housing to the main body on which the drive motor is mounted. In the conventional case, when the coupling portion of the main body and the housing is formed in an undercut shape consisting of “b”, the housing is coupled onto the main body. Rather than simply seating, there is an inconvenience of having to complete the tightening by applying a rotation operation separately.

Accordingly, the present invention improves the internal structure of the housing on which the grinding screw is mounted and the juicer including a brush to effectively discharge the juice generated by the pressing by adding a brush rotating portion surrounding the drum mounted on the housing To provide.

In addition, the present invention is to provide a juicer to simplify the coupling and separation by configuring the coupling portion formed on the housing and the main body in a simple straight shape in the process of detaching the housing to the main body.

Juicer comprising a brush in accordance with the present invention provided to achieve the above object is formed in the inlet, the rotating shaft hole is formed in the inner center, is installed in the lower portion of the cover, the waterproof cylinder with a through hole in the center And a housing having a circular mandrel guide jaw protruding from the bottom of the waterproof cylinder, a brush rotatably contacting an inner side surface of the housing, and a first opening formed at a predetermined angle in the mandrel guide jaw. It includes an interlocking gear disposed in, the second opening formed in the mandrel guide jaw is characterized in that it is in communication with the juice outlet extending from the outer lower surface of the housing.

The juicer is installed in the housing, the outer wall is made of a network structure formed with a plurality of net holes, a mandrel having a plurality of wall blades formed on the inner surface, the upper rotary shaft is formed to be rotatably inserted into the rotating shaft hole in the upper portion A plurality of screw spirals are formed on an outer surface thereof, and further comprising a grinding screw having a lower rotating shaft having a square shaft hole, a brush rotating part including the brush, and a driving part connected to the housing to supply power to the grinding screw. The interlocking gear may rotate in conjunction with the grinding screw and the brush rotating unit.

The brush may rotatably contact the inner side of the housing and the outer surface of the mandrel.

The brush may extend downward to approach an inner bottom of the housing.

A screw gear is formed in the lower part of the grinding screw, and the screw gear and the brush gear are coupled to the interlocking gear to be driven, thereby rotating in the opposite direction.

The fixing groove formed on the bottom of the housing is seated on the fixing protrusion formed on the upper end of the body, the fixing protrusion may be a straight shape.

In the present invention, the grinding screw is operated at a very low speed and simultaneously compressed and crushed by the strong torque of the grinding screw, so that the inherent taste and nutrition of beans or fruits remain intact. The present invention makes it easy to pull down the juice component that can be attached to the outer surface of the mandrel and the inner surface of the housing by placing the brush rotating part between the housing and the mandrel that contains the grinding screw. Juice to the material supplied through the above process is made smoothly.

The juice discharge port extending from the outer lower surface of the housing is configured to communicate with the opening formed in the mandrel guide jaw so that the juice collected in the housing can be smoothly discharged.

On the other hand, the present invention enables the smooth discharge of the residue generated by placing the interlocking gear which enables the interlocking rotation of the grinding screw and the brush rotating portion on the mandrel guide jaw of the housing in a separate place from the housing discharge hole to the housing discharge hole. Let's do it.

In addition, since the housing is assembled vertically above the drive unit, the supplied material naturally moves downward due to the rotation of gravity and the grinding screw, and the juice is quickly picked up and there is no juice sticking phenomenon. It can be juiced.

The outer surface of the grinding screw 40 is formed with one or more screw spirals 43 in contact with the interior of the drum (30). The lower center of the grinding screw 40 is provided with a lower rotating shaft 42 in which a square shaft hole 42a is formed. On the other hand, the lower surface of the grinding screw 40 is formed with a screw gear 44 is formed with a tooth at a predetermined interval around the lower rotary shaft 42.

The mandrel 30 forms a hollow cylindrical structure penetrating up and down, and the inner wall is formed with a wall surface 31 in the vertical direction at regular intervals. The wall blade 31 can be formed by dividing the long and the short, and it is possible to set the length in various ways. As the injected material is transferred downward by the grinding screw 40, the protrusion height is lowered toward the lower side from the inner surface of the mandrel 30 so that it can be crushed finely.

The outer wall of the mandrel 30 has a structure of a net 32 to allow the juice generated from the pulverized material to pass through. The lower the lower the size of the material is, the lower the size of the manhole becomes from the top to the bottom. Can be small. In addition, since the material is finely pulverized at the middle height of the mandrel 30, the middle part of the mandrel 30 is formed in a closed structure rather than the net 32 structure, so that fine debris is trapped in the net while being trapped in the net. Can be prevented from being mixed inside the juice or the juice can be obtained.

On one side of the bottom surface of the mandrel 30 is formed a waste communication hole 35 penetrating up and down. The dregs communication hole 35 is able to communicate with the housing discharge hole 25 formed in the bottom surface of the housing 20 up and down so that the dregs in the mandrel 30 can be smoothly discharged.

The brush rotating part 50 includes an upper ring 51, a lower ring 52, and a support bar 53 connecting the upper ring 51 and the lower ring 52, and the mandrel 30 has a brush rotating part. 50 is inserted and fastened. The brush 54 is rotated in contact with the outer surface of the mandrel 30 and the inner surface of the housing 20. That is, the brush 54 acts to push down the juice component buried in the surface or the housing 20 of the mandrel 30 in the state extracted through the mandrel 30.

On the other hand, the brush rotating unit 50 includes a brush gear 55 extending from the lower end of the lower ring 52, the brush gear 55 is engaged with the interlocking gear 29 to rotate.

Brush 54 may extend to reach the inner bottom of housing 20. In this state, the juice component accumulated on the inner bottom of the housing 20 is collected by the rotating brush 54 to be discharged to the outside of the housing 20.

Specifically, it will be described with reference to FIG. Brush 54 includes an outer brush 54a and an inner brush 54b, the outer brush 54a rotating in direct contact with the inner side of the housing 20, and the inner brush 54b rotating on the drum 30. Rotate in contact with the outer circumferential surface of).

 In the present invention, the outer brush 54a further extends downwardly from the lower ring 52 to approach the inner bottom of the housing 20. Proximity to the inner bottom in the above may be enough to scrape the juice between the lower end of the outer brush 54a and the inner bottom of the housing 20. This structure can provide a way to effectively collect the juice extracted in the housing 20. Since the brush 54 is rotated in contact with the housing 20 and the mandrel 30, the brush 54 is made of an elastic material so that the brush 54 may be restored to its original state even when deformation occurs in the rotation process.

The housing 20 accommodates the grinding screw 40, the mandrel 30, and the brush rotating part 50 therein, and a binding jaw 28 is formed at the inner circumference of the upper end, and a through hole (in the lower part of the center). The waterproof cylinder 21 in which 21a) is formed is formed to protrude upward. The binding jaw 28 is coupled to the binding protrusion 13 formed on the cover 10 and functions to firmly fix the cover 10 to the housing 20.

The housing 20 has a hollow cylindrical structure with an open top, and a mandrel guide jaw 22 having a through hole 22a is formed in a circular shape at an inner center thereof. The mandrel guide jaw 22 serves as a guide in the process of inserting and fastening the mandrel 30 into the housing 20. The mandrel projections 34 protruding from the bottom side of the mandrel 30 have the mandrel. It is securely fastened by fixing to the net drum seating groove 27 formed in the guide jaw (22).

Meanwhile, the fixing groove 28a formed at the bottom of the housing 20 may be seated on the fixing protrusion 2 formed at the upper end of the driving unit 60. The fixing protrusion 2 may have a straight shape without bending, and may be easily mounted in the vertical direction when the housing 20 is positioned on the driving unit 60.

2 and 4, a housing discharge hole 25, a first opening 26, and a second opening 24a are formed in the mandrel guide jaw 22. The housing discharge hole 25 communicates with the dreg communication hole 35 of the mandrel 30.

The housing 20 has a dregs outlet 23 and a juice outlet 24 extending from the lower outer surface, respectively. One side of the juice outlet 24 is configured to be in direct contact with the side of the waterproof cylinder (21). That is, the second opening 24a formed in the mandrel guide jaw 22 communicates with the juice outlet 24. By configuring as described above, the juice component flowing in the housing 20 can be easily discharged along the juice outlet 24.

Hereinafter, the operation principle through the interlocking gear 29 will be described with reference to FIGS. 5 and 6.

The interlocking gear 29 is rotatably seated in the first opening 26 of the mandrel guide jaw 22. The interlocking gear 29 is engaged with the screw gear 44 and the inside of the mandrel guide jaw 22, and the brush gear 55 is engaged with the outside of the mandrel guide jaw 22. That is, the interlocking gear 29 is engaged with the screw gear 44 on the inside and the brush gear 55 on the outside.

The grinding screw 40, which receives power from the square shaft 63 of the driving unit 60, transfers power to the interlocking gear 29 through the screw gear 44. For example, when the grinding screw 40 rotates clockwise as shown in FIG. 6, the interlocking gear 29 rotates counterclockwise. Subsequently, the counterclockwise rotation of the interlocking gear 29 causes the brush rotating part 50 meshed with the interlocking gear 70 by the brush gear 55 to rotate counterclockwise. That is, the forward rotation of the screw gear 44 may cause the brush gear 55 to rotate in the reverse direction by the interlocking gear 29.

The drive unit 60 includes a drive motor 61 and a speed reduction device 62 disposed above the drive motor 61. The drive unit 60 is coupled to the vertical lower end of the grinding screw 40 to rotate the screw 20 at low speed, the square shaft 63 protruding on the top of the reduction device 62 passes through the through hole (21a). It is inserted into the square shaft hole 42a of the grinding screw 40. The square shaft 63 is connected to the drive motor 61 and the reduction gear 62 to rotate.

Reduction device 62 used in the present invention serves to reduce the rotational speed of the drive motor 61, so that it can rotate at a much lower rotational speed than the prior art. Specifically, the reduction gear 62 may be configured in the form of a planetary gear assembly, and the rotation speed of the drive motor 61 between 2400 and 3200 rpm is 20 to 20 by using a reduction ratio between 5 and 9 continuously. It enables rotational driving of the grinding screw 40 at a low speed between 90 rpm.

 Referring to the operation of the juicer according to an embodiment of the present invention configured as described above are as follows.

When the material is injected into the injection hole 11 of the cover 10, the upper blade of the grinding screw 40 and the lower surface of the injection hole 11 are intersected and the material is cut and introduced into the mandrel 30. The material introduced into the mandrel 30 is pulverized and compressed gradually as it is transported down. In this process, the juice flows out of the mandrel 30 through the manhole 32 of the outer wall to open the juice outlet 24. Is discharged through.

The residue that reaches the dreg communication hole 35 through the wall blade 31 of the mandrel 30 by the rotation of the grinding screw 40 is extruded into the housing outlet hole 25 of the housing 20, and again It is discharged out of the juicer through the outlet 23.

The material pulverized in the mandrel 30 is finally compressed and dehydrated. In this process, most of the water (juice) is discharged to the outside through the net hole 32 of the wall of the mandrel 30, and the juice outlet 24 is discharged. But some of it is introduced into the inner bottom of the housing 20 through the screw 20 and the mandrel 30. In this case, since the juice outlet 24 is formed along the bottom surface of the housing 20 such that the juice outlet 24 is in close contact with the lower surface of the waterproof cylinder 21, the effective collection of the pressed juice is possible.

In addition, in the case of juice that adheres to the inner surface of the drum 40 or the housing 20 and does not flow well, the brush 54 of the brush rotating part 50 may be rotated to easily flow down to the lower part of the housing 20. have.

Since the grinding screw 40 and the mandrel 30 are vertically assembled and operated in the housing 20, the speed of the grinding screw 40 and the mandrel 30 is lower than that of the conventional juicer which is assembled and operated horizontally. The juice also has the advantage of being able to flow down easily.
