Description

Juicer

The present invention relates to a juice apparatus, and more particularly, to a juice apparatus for maximizing the efficiency of power transmission and maximizing the life of parts by driving each of the rotating brush and the screw used in the juice independently.

Juicer is a device for processing vegetables or fruits in the form of liquid or juice. Several types of juicers are known which can be conveniently used for home or commercial purposes. The most common juicer adopts a method in which a material is placed in an inlet and then crushed by a blade rotating at high speed. However, this kind of juicer is limited in making juice by crushing tough ingredients such as green vegetables of stems or leaves.

On the other hand, a juicer for compressing vegetables or fruits between the rotating screw and the mandrel to make juice or juice (especially green juice) has been developed in the past. In such a juicer, a screw and a drum are arranged in an upper open-type juicer, and a lid in which a material inlet is formed is coupled to the upper portion of the juicer. A shaft hole is formed in the lower part of the lid, and an upper end of the screw is provided with a shaft that is rotatably fitted in the shaft hole. The material inlet is formed small in the lid, avoiding the axial hole. The juicer is mounted on a main body with a built-in drive, and the screw is connected to the drive shaft of the drive outside the juicer module and rotates.

1 is a conventionally proposed juicer first embodiment (Patent Registration No. 10-0755440) is a through hole formed in the upper one side, the lid is formed in the center of the rotating shaft hole; It is installed in the lower portion of the lid, the guide jaw is formed at the bottom, the outer bottom portion is formed with a discharge outlet and juice outlet spaced apart, a waterproof cylinder with a through hole is formed at the bottom of the center, the pressure around the bottom of the waterproof cylinder A housing in which a discharge path is formed; An upper rotary shaft is formed in the upper part to be rotatably inserted into the rotary shaft hole, and a plurality of screw spirals are formed in the outer surface, and an inner ring in which a plurality of screw gears inserted and rotated in the pressure discharge path is formed in the lower direction. A protrusion having a lower space in which the waterproof cylinder is inserted into the inner ring and inserted into the inner ring, and having a square shaft hole formed at a lower center thereof; The outer wall is made of a network structure for discharging the juice to the juice outlet, the inner surface is formed with a plurality of wall blades in the vertical direction, the mandrel formed to be inserted into the guide jaw; A rotating brush mounted between the housing and the mandrel and having a brush holder mounted with a brush to continuously sweep the mandrel and the housing; A rectangular shaft is inserted into the rectangular shaft hole through the through-hole of the waterproof cylinder, and includes a driving unit for rotating the screw at a low speed. A housing for accommodating the screw is vertically fixed to an upper side of the driving unit. It is characterized by releasing the residue while crushing and grinding the inserted material into the juice.

In particular, the screw and the rotating brush as shown in Figure 2 is a structure in which the screw is driven when the drive shaft is rotated, and then the intermediate gear transmits power to the brush gear through the screw gear when the screw is driven.

That is, the screw gear 280, the intermediate gear 590 and the brush gear 440 is designed to engage, so that when the screw rotates, the brush holder rotates to continuously wipe the outer wall of the mandrel and the inner wall of the housing. .

However, in the above structure, since the brush gear receives power from the driving unit through the intermediate gear, a load is applied at two points of the intermediate gear, which causes a problem that the life of the intermediate gear can be drastically reduced by applying pressure. Since the gear must pass through the intermediate gear in order to rotate, there is a problem that the complete operation can not be achieved by receiving power indirectly.

Hereinafter, the configuration of the crimping screw 200 and the liquid strainer 300 will be described in detail with reference to FIGS. 10 and 11.

The screw body 210 of the crimping screw 200 has an inverted cone shape and may be injected into a resin material. And, the coupling portion 220 is formed through the screw body 210, and has a coupling hole so that the motor shaft is fitted. In addition, at least one thread 230 is formed on the outer circumferential surface of the screw body 210. Screw 200 having such a configuration, along with the above-described motor and the liquid sieve 300 to provide a load on the juice object substantially. Further, the pressing screw 200 serves to squeeze the juice object together with the liquid sieve 300. That is, after the device is operated, when the user inputs the juice object through the upper cover to the inside of the outer housing, the juice object moves downward along the inner circumferential surfaces of the screw 230 and the liquid sieve 300 of the screw 200. The juice object is first juiced while being pressed between the outer circumferential surface of the screw 200 and the inner circumferential surface of the liquid strainer 300 during movement.

In conclusion, if the above-mentioned juice process is rearranged, when the screw 200 for the compression is rotated by the motor, the juice object is lowered along the thread 230, while the primary juice between the screw thread 230 and the liquid sieve 300. And, while the primary juice is progressing the juice groove 240 passes through the juice projections 310, the juice object is a second juice between the juice.

Hereinafter, the rotary brush unit will be described in more detail with reference to FIGS. 12 and 13.

The rotary brush part 400 includes a lower rotary part 410, an inclined support part 420, an upper support part 430, and a fitting brush 440.

The lower rotating part 410 is formed in a ring shape and a plurality of gears 411 are arranged at a predetermined interval on the bottom surface.

The inclined support part 420 is disposed at a predetermined interval on the lower rotating part 410 but is inclined at a predetermined angle, and the hollow hole 421 is formed long in the longitudinal direction.

The upper support part 430 connects and installs the upper side of the inclined support part 420, and has a ring shape.

The fitting brush 440 is formed by forming two protruding pieces 441 on one side by forming a vertical panel and one protruding piece 442 on the lower side of the other side, and the inclined support part 430. It is fitted into the hollow hole 421 of the.

The rotating brush part 400 formed as described above has a second power transmission gear 110 installed on an upper portion of the first rotation shaft 103 constituting the driving part 100, and a lower portion on the second power transmission gear 110. The gear 411 of the rotating unit 410 is engaged with each other, and as the gear connected to the second power transmission gear 110 rotates as described above, the entire rotating brush unit 400 rotates.

Since the brush 440 is mounted on the inclined support part 420 of the rotary brush part 400, the fitting brush 440 rotates to wipe off the outside of the liquid sieve 300. Since the 440 is installed to be inclined, the liquid that is present in the outer housing 500 may be wiped while lifting the liquid, and the outside of the liquid sieve 300 may be cleaned more easily and cleanly.

That is, conventionally simply used by mounting a vertical brush simply wipe the outside of the liquid sieve, it was difficult to easily wipe the outside of the liquid sieve in the absence of water, the present invention is a brush for fitting in the inclined form Since the mounting brush 440 moves, the liquid 440 moves up while lifting the liquid existing on the bottom surface of the outer housing 500, thereby generating a vortex phenomenon, thereby making the outside of the liquid sieve 300 easier. It is wiped off.

Looking at the overall operation of the present invention.

First, when the motor is driven, the main drive shaft 101 is rotated. The main drive shaft 101 is directly connected to the motor, the main drive shaft 101 is rotated by the operation of the rotor constituting the motor to rotate.

In addition, when the main drive shaft 101 rotates, the first rotary gear 102 geared to the main drive shaft 101 rotates, and the first rotation shaft 103 rotates in association with the first drive shaft 101. The first power transmission gear 104 and the second power transmission gear 110 connected to the 103 are rotated.

Then, the second rotary gear 105 connected to the first power transmission gear 104 rotates, and accordingly, the second rotating shaft 106 rotates, so that the pressing screw 200 connected to the second rotating shaft 106 is rotated. Will rotate. As the pressing screw 200 rotates, the juice of various materials proceeds.

At the same time, the rotating brush part 400 geared to the second power transmission gear 110 is rotated, so that the rotating brush part 400 wipes the outside of the liquid sieve 300 to squeeze the continuous liquid. Make this possible. In this case, since the inclined support part 420 is installed and the fitting brush 440 is mounted on the inclined support part 420, the rotating brush part 400 spreads the liquid accumulated in the outer housing 500. While wiping the outside of the liquid sieve 300, it is possible to more easily wipe the outside of the liquid sieve (300).

Comparing the features of the present invention made as described above with the prior art are as follows.

First, the present invention, while the second rotary gear 105 receives the rotational force according to the motor drive and then directly transfers the rotational power to the rotating brush unit 440 through the second power transmission gear 110, the prior art There is a difference in transmitting the rotational force according to the motor drive to the rotating brush part through the idle gear which is an intermediate gear.

Due to this difference, the present invention has the advantage that the crimping screw 200 and the rotary brush part 400 are independently rotated to receive stable power, and thus the operation efficiency is high and the failure is minimized. Since the use of gears causes the screw and the rotating brush to operate using a single power, not only the operation efficiency is lowered but also the gears are bitten on both sides of the idle gear, thereby increasing the probability of failure and shortening the life of parts.

That is, in the present invention, the crimping screw 200 and the rotatable brush portion 400 are rotated by independent power in a state in which the rotatable shaft for rotating the crimping screw 200 and the rotatable brush portion 400 is provided, respectively. In the prior art, since the power transmitted to the crimping screw is transferred to the idle gear, the idle gear must mesh well with the crimping screw and the rotary brush at the same time, thereby increasing the risk of breakage when the bite is disturbed, and the idle gear is crimped. Since it is engaged with the screw and the rotary brush at the same time, either rapid acceleration or rapid deceleration to either the screw or the rotary brush may be overloaded, resulting in the loss of parts.

However, the present invention transmits power to the screw 200 and the rotary brush 400 for the compression, respectively, because the second power transmission gear 110 and the rotary brush 400 is operated by one gear meshing. Strong power can be provided, and since there is only one contact surface, there is an advantage that the risk of failure is minimized because there are no parts that are overloaded even when the rotation axis is suddenly accelerated or decelerated. That is, in the prior art, since the idle gear relays power, if one component is suddenly accelerated or rapidly decelerated, the other component may not immediately react and the idle gear may be damaged. The absence of idle gears minimizes the risk of component breakage.

Further, in the related art, since the rotating brush receives power through the crimping screw, the deceleration is made in the process of transmitting power to the crimping screw, and again, the deceleration is made in the process of transmitting power from the crimping screw to the rotating brush. Although the deceleration is performed a total of two times, the present invention has a difference in that the rotational power of the rotating brush can be made strongly because only one deceleration is performed since power is directly transmitted from the second power transmission gear to the rotating brush part.

That is, in the related art, since the power is transmitted to the rotating brush by decelerating twice, the rotational speed of the rotating brush is inevitably lowered. However, the present invention decelerates once and the power is transmitted to the rotating brush, thereby rotating the rotating brush. The speed can be kept fast so that the liquid sieve can be cleaned more effectively.

Therefore, as in the present invention, the rotation brush unit 400 is provided with the rotational power by a separate power shaft, which is an improvement in terms of the efficient operation of the device or the life of the component.

Second, since the rotary brush part 400 of the present invention has the inclined support part 420, and the fitting brush 440 is mounted on the inclined support part 420, the rotary brush part 400 rotates in liquid. While the rotating operation is made by lifting, but the prior art is designed to have a vertical support, there is a difference that the operation of rotating while lifting the liquid during rotation is not made.

That is, the present invention can wipe the outside of the liquid sieve (300) strongly while generating a vortex because the fitting brush 440 to wipe the outside of the liquid sieve (300) while rotating while lifting the liquid, The prior arts cannot gently wipe the outside of the liquid sieve because the brushes are installed vertically.

That is, the liquid is buried in the upper portion of the upper portion of the liquid sieve 300, the present invention, since the brush 440 for fitting the liquid to wipe the liquid sieve 300 while causing the vortex phenomenon to raise the liquid, the upper portion of the liquid sieve It is easy to wipe off the liquid on the outer surface, but the prior art is difficult to wipe off the upper end of the liquid sieve because it does not have the ability to pump the liquid. In particular, since the upper part of the liquid sieve 300 wipes the upper end of the liquid sieve 300 only with a brush, it is difficult to easily wipe it, but may be contaminated at the above point. Wipe off more easily.

As a result, the present invention allows the rotary brush part 400 to have the inclined support part 420 to more easily wipe the outside of the liquid strainer 300 compared to the related arts.

The above description is merely illustrative of the technical spirit of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention.

That is, the embodiments disclosed in the present invention are not intended to limit the technical spirit of the present invention but to describe the scope of the technical spirit of the present invention by these embodiments.

Therefore, the protection scope of the present invention should be interpreted by the claims below, and all technical ideas within the equivalent scope will be construed as being included in the scope of the present invention.
