Description

Juicer

The present invention relates to a juicer capable of extracting juice from vegetables, fruits or extracting soy milk from beans, and more particularly to a juicer which performs an excellent juice extraction function regardless of the type of vegetable or fruit. Moreover, by using a very low speed rotation method to keep the juice fresh, the size and noise of the juicer are greatly reduced, and the assembly, disassembly and cleaning of the juicer can be simply performed.

In order to get a healthy life, more and more juices (including green juices) are being prepared and consumed directly at home. To this end, a variety of devices have been provided which can simply extract juice from vegetables or fruits at home.

Existing juicers squeezing materials placed in the inlet at high speed and producing juice by centrifugation. However, the conventional juicer has the drawback that in the high-speed extrusion process, the inherent flavor and nutrients contained in the fruit may be destroyed, and it is difficult to extract green juice from the vegetable having the branches or leaves. It is also difficult to extract juice from fruits with high viscosity, such as kiwi or strawberry, and it is completely impossible to extract soy milk from beans. In addition, for continuous extraction of juice from vegetables or fruits, it is necessary to frequently disassemble and clean the juicer to remove debris (i.e., residue) trapped in the filter mesh.

Korean Utility Model Registration No. 190676 (which has been granted to the applicant) discloses a grinder combined with a juicer.

The driving unit 600 has a polygonal shaft 610 protruding upward to be inserted into the polygonal shaft hole 230 of the screw 200 through the through hole 520 and rotating the screw at a low speed; and a plurality of fastening grooves 515 inserted into the outer casing 500 to fix the outer casing 500 The fastening protrusion 630.

The polygonal shaft 610 is coupled to a motor and a speed reducer (not illustrated) for rotation.

A plurality of engaging jaws 130 project from the edges of the lower end portion of the cover 100, and a plurality of engaging projections 510 are formed on the outer periphery of the upper end of the outer casing 500. When the engaging projection 510 is engaged with the engaging jaw 130, the cover 100 is detachably fastened to the outer casing 500.

On the upper surface of the driving unit 600, a pair of engaging hooks 620 fixed to the outer casing 500 fastened to the cover 100 are additionally provided on the upper surface of the driving unit 600. The surface prevents the juicer from vibrating.

The speed reducer used in the present invention is used to reduce the rotational speed of the motor and to rotate the screw at a very low speed compared to the screw of a conventional juicer.

The operation of the juicer constructed as above in accordance with a specific embodiment of the present invention will be described.

When the material is placed in the inlet 110 of the cover 100, it is moved to the inside of the mesh drum 300 along the inclined surface 140 formed on the lower surface of the cover 100. The material moved into the mesh drum 300 is finely ground and pressed as it is forcibly conveyed downward due to the rotation of the screw 200 and the wall blade 310. The juice produced in this process flows out of the mesh drum through the mesh formed on the outer wall of the mesh drum 300, and is then discharged through the juice outlet 560.

The residue reaching the bottom ring 340 of the mesh drum 300 by the rotation of the screw 200 is pushed by the discharge port 225 of the lower end of the screw 200, and guided to the mesh drum discharge hole 360 along the discharge inclined surface 350. In this case, if a predetermined pressure is applied to the filler 575 that blocks the outlet of the casing discharge hole 540, a gap is generated between the outlet of the discharge hole 540 and the filler, and the residue is discharged through the gap. The discharged residue then exits the residue outlet 570 of the juicer.

The ground material is finally pressed at the bottom ring 340 of the mesh drum 300. During this process, most of the juice flows through the mesh formed on the outer wall of the mesh drum 300 to the outside, and is then discharged through the juice outlet 560, and only a portion of the juice is pushed into the inner ring 250 of the screw 200 and the mesh drum 300. The inner ring is inserted into the gap between the holes 380 to flow to the pressure discharge passage 580. However, since the pressure discharge passage 580 is connected to the juice outlet 560, the portion of the juice is finally discharged to the outside via the juice outlet 560.

If the pressure discharge passage 580 is not connected to the juice outlet 560, the juice pushed into the gap between the inner ring 250 of the screw 200 and the inner ring insertion hole 380 flows through the waterproof cylinder 530 and via the through hole 520 and the polygonal shaft 610. The gap between them is discharged from the outer casing. This may cause contamination of the motor or reducer of the drive unit 600 and through the outer surface of the juicer.

Even though the juice is thick and therefore does not flow naturally, it can be forcibly guided to the juice outlet 560 by the screw gear 280 of the inner ring 250.

The reason why the screw gear 280 is wing-shaped is to more efficiently discharge the thick juice having a high viscosity to the juice outlet 560.

The screw gear 280 is used to rotate the rotating brush 400 by transmitting the power of the driving unit 600 to the rotating brush 400. In other words, since the screw gear 280 and the brush gear 440 are engaged by the intermediate gear 590, the brush holder 430 rotates when the drive unit 600 rotates the screw 200. Therefore, the mesh brush 410 and the outer casing brush 420 disposed on the brush holder 430 continuously clean the outer wall of the mesh drum 300 and the inner wall of the outer casing 500, respectively, and thus can effectively flow the thick juice or the soybean milk. In addition, since the outer wall of the mesh drum 300 is continuously cleaned, it is not necessary for the user to frequently disassemble and clean the mesh drum 300.

The inner surface of the intermediate portion of the mesh drum 300 has a sealing structure, and in addition to the wall blade 310, a plurality of grinding blades 390 are protruded from the sealing structure. A filter screen 320 is formed on the upper portion of the mesh drum 300, and a press net 330 having a fine mesh is formed in the lower portion of the mesh drum 300.

Therefore, the juice generated when the material is forcibly transferred along the wall blade 310 of the mesh drum 300 flows through the filter screen 320 to the outside, and the inner surface of the material is in the middle portion of the plurality of grinding blades 390 having the sealing structure. The juice produced when the surface is finely ground is discharged to the juice outlet 560 via the press web 330.

The residue is discharged to the mesh drum discharge hole 360 along the bottom discharge inclined surface 350.

At this time, the outer ring 260 is used to smoothly move and discharge the residue by expanding the contact area of the residue moving along the discharge inclined surface 350 and guided to the mesh drum discharge hole 360 by being pushed by the discharge port 225 of the screw 200.

The circular projection 370 is inserted into the circular projection insertion hole 290 at the lower portion of the screw without any gap therebetween, and the residue is prevented from flowing into the pressure discharge passage 580 to the utmost extent even when pressure is applied to the residue at the bottom ring 340.

In addition, since the screw 200 and the mesh drum 300 are longitudinally assembled in the outer casing 500, the speed of downward movement of the material is improved and the juice in the outer casing 500 is easy compared to the conventional juicer in which the screw and the mesh drum are horizontally assembled. It flows downward without remaining in the outer casing 500.

However, it is not necessary to form all the upper sides of the sensor detecting unit 680 on the same plane, and the cover is sufficient to rotate to some extent so that the movement of the sensor generating unit 160 is not disturbed by the rotation of the cover 100. . As described below, when the cover 100 is engaged with the upper end of the outer casing 500 and separated from the upper end of the outer casing 500, the cover 100 is rotated in one direction, and in this case, the sensor generating unit 160 is formed to be free from detachment. In the case of the detector detecting unit 680, the upper side of the sensor detecting unit 680 is passed.

The sensor detecting unit 680 detects the signal of the sensor generating unit 160 and determines whether the motor provided in the driving unit 600 is operated according to the sensed signal.

In the juicer of the present invention, the cover 100 is placed at the uppermost portion and finally engaged with the outer casing 500. In an initial state in which the cover 100 is placed at the upper end of the outer casing 500 to engage the cover 100 with the upper end of the outer casing 500, the sensor generating unit 160 may not be placed just above the sensor detecting unit 680.

If the user places the sensor generating unit 160 on the upper side of the sensor detecting unit 680 by rotating the cover 100 in one direction, wherein the cover 100 is engaged with the outer casing 500, the cover 100 is engaged with the outer casing 500 to present Closed state. At this time, the sensor detecting unit 680 that detects the signal from the sensor generating unit 160 sends an operable signal to the driving unit 600 to operate the juicer.

The sensor generating unit 160 may have a magnet therein, and the sensor detecting unit 680 can control the operation of the juicer by detecting the strength of the magnetic field formed by the magnet.

In contrast, if the user rotates the cover 100 in the opposite direction to separate the cover 100 from the outer casing 500, the sensor generating unit 160 is separated from the sensor detecting unit 680, and thus the sensor detecting unit 680 transmits The signal is operated to interrupt the juicer operating drive unit 600 such that the juicer ceases its operation or is in an inoperable state.

According to the present invention as described above, since the operation of the juicer can be controlled according to the engagement state of the cover 100, the stability of the juicer can be improved. Further, since the cover 100 is first separated from the outer casing 500 by the rotation of the cover 100, and then the screw 200, the mesh drum 300, and the rotary brush 400 are sequentially separated, the juicer can be easily assembled/disassembled to facilitate cleaning of the inside of the juicer.

An O-ring 520a is provided in the through hole 520a, which is made of a material such as rubber, urethane, and the like. The O-ring 520a is fixedly engaged with the inside of the through hole 520. The O-ring 520a is annular, and the lower end of the lower rotating shaft 240 is inserted therein. Figure 8 illustrates the engaged state of the O-ring.

The lower end of the lower rotating shaft 240 is inserted into the O-ring 520a and engaged with the polygonal shaft 610. The O-ring 520a is formed to fit the diameter of the lower end portion of the lower rotating shaft 240, and is in close contact with the lower rotating shaft 240 within a limit that the O-ring 520a does not interfere with the extremely low speed of the lower rotating shaft 240.

In addition to the waterproof cylinder 530, an O-ring 520a is also provided to prevent penetration of the extracted juice into the drive unit 600 and to double the safety of the juicer.

Another specific embodiment of the present invention will be described with reference to FIGS. 10A through 10C. Juicer.

The filler member 575 is composed of an insertion unit 575a and a rotation unit 575b. The insertion unit 575a is formed to fit the insertion groove 576 to completely seal the insertion groove 576. The rotation unit 575b larger than the insertion unit 575a is formed integrally with the insertion unit 575a, and is in close contact with the end portion of the insertion groove 576. The rotating unit 575b is formed to allow the user to grip and withdraw the insertion unit 575a with the insertion unit 575a inserted into the insertion groove 576.

One side of the rotating unit 575b is rotationally engaged with the lower surface of the outer casing 500, and the insertion unit 575a inserts or withdraws the insertion groove 576 as the rotating unit rotates around the rotating shaft. That is, the rotating unit 575b rotates about a rotating shaft formed in a direction perpendicular to the lower surface of the outer casing 500, and thus the filler 575 closes and opens the insertion groove 576.

Since the rotating unit 575b is rotationally engaged with the outer casing 500, the filler 575 smoothly inserts or withdraws the insertion groove 576, and thus the filler is prevented from being lost, while the rotating unit 575b can be easily operated.

Industrial applicability

As can be seen from the above, the juice extractor of the present invention has the following effects.

Firstly, by using a very low speed screw extrusion instead of using a high-speed rotary blade for extrusion, the nutrients and inherent flavors contained in juice, soy milk, etc. are maintained to the utmost, and extensive juice extraction and vegetables and The type of fruit has nothing to do with it.

Second, since the outer casing of the juicer is longitudinally assembled on the upper side of the drive unit, the material naturally moves downward by gravity and rotation of the screw, and the juice extraction speed is increased. Therefore, the extracted juice flows down sufficiently without guaranteeing It stays in the outer casing and therefore various vegetables and fruits can be quickly juiced.

Third, since the screw is fixed in both directions, the screw is prevented from vibrating, and thus the screw is prevented from shaking or striking the inner wall of the mesh drum during operation of the screw to reduce noise generation and prevent screw wear.

Fourth, the winged screw gear is placed on the lower surface of the inner ring of the screw, and thus excellent juice extraction efficiency can be achieved in the preparation of thick juice or soy milk.

Fifth, by connecting the pressure discharge passage provided in the outer casing to the juice outlet, the juice can be prevented from flowing into the drive unit.

Sixth, the residue is discharged more smoothly by additionally forming an outer ring on the screw, and the residue inflow pressure discharge passage is minimized by forming a circular protrusion on the mesh drum.

Seventh, by forming an inclined surface on one side of the lower surface of the juicer cap, the material can be automatically introduced into the inlet without applying pressure to the material.

Eighth, by installing a rotating brush that continuously cleans the mesh between the mesh drum and the outer casing, the user does not need to frequently disassemble and clean the juicer.

Ninth, by mounting the brush gear in the lower portion of the rotating brush and rotating the brush via the intermediate gear connected to the screw gear rotated by the driving unit, it is not necessary to separately provide power.

Tenth, since the filler is inserted in the outlet of the casing discharge hole and a gap is generated between the filler and the outlet only when a specified pressure is applied to the filler, the juice discharged to the residue outlet can be minimized.

Eleventh, since the micro switch disposed on the drive unit is operated only when the outer casing in which all components are assembled is placed on the drive unit, the press is improved The safety of the juice machine reduces energy consumption and saves energy.

Twelfth, a sensor generating unit and a sensor detecting unit are provided to prevent a safety accident, and only the cover is separated from the outer casing to facilitate the overall assembly, disassembly and cleaning of the juicer.

Thirteenth, an O-ring is formed in the center of the through hole to effectively prevent the extracted juice from penetrating into the driving unit 600, and thus the contamination and damage of the juicer can be prevented.

Fourteenth, since the rotary unit is rotationally engaged with the lower surface of the outer casing, the filler member can smoothly open and close the insertion groove and prevent the filler from being lost.

Although the present invention has been described in connection with the preferred embodiments of the present invention, it is understood that the invention is not limited to the specific embodiments and drawings. On the contrary, the intention is to cover various modifications and changes in the spirit and scope of the appended claims.
