Description

[0001] The present invention relates to a scissor-type pre-cutting module,

The present invention relates to a juicer, and more particularly, to juicer having a pretreatment unit and implementing a pretreatment cutting of a juicer prior to juicing with a screw.

The vertical centrifugal separator includes a screw into which a juice object such as fruit or vegetable is put and cut, conveyed, crushed or pressed. The screw is provided on the inner side of the drum, and the juice is divided into juice and pulp by the rotation of the screw in the process of passing the fruit juice between the mesh net and the drum, including the mesh net. The juice and pulp are separately collected at the bottom of the drum and are discharged separately through the respective discharge portions.

The conventional vertical centrifugal separator is divided into a type in which a mesh drum is adopted and a type in which a mesh net is integrally provided with a screw without adopting a network drum. An example of the former is Korean Open Publication No. 2012-0029638, and an example of the latter is Korean Open Publication No. 2012-0042606.

Of the types in which the mesh net is integrally provided with the screw, both the juice and the pulp are discharged in the drum and the pulp is discharged to the drum side by the rotation of the screw. In the latter case, it is possible to adjust the pulp amount by attaching an appropriate mechanism to the pulp discharge part, and it is possible to extract the juice again from the pulp. As an example of the former, Korean Laid-open Publication No. 2013-0042991 can be cited, and as an example of the latter, Korea Laid-open No. 2016-0014959.

In order to juice the juice object in such a juicer, the juice object, which is the base material, must be injected through the injection port into the drum where the screw is located. However, when a tough product such as a leaf stay is injected as a juice object, a phenomenon occurs in which the mesh net or the discharge portion is clogged by long fibers included therein.

To prevent this, there is a master clerk who implements the preprocessing.

Korean Utility Model Publication Nos. 2015-0102414, 2015-0094101 and 2015-0115259 by the present applicant disclose a master clerk including a cutter for pre-processing.

In the above-described conventional technique, the user must push the juice object into the injection port in order to perform pre-processing cutting, which is inconvenient. In order to solve this problem and sharpen the cutter blade in order to improve the cutting function, there is a safety problem that the user's hands may be bent in the process of pushing the juice object into the injection port.

Although the present invention has been described by taking the master secretary as an example, the same principle may be applied to devices other than master secretary. For example, the scope of the present invention is also applicable to a mixer, a green pot, and the like.

Hereinafter, "fruit juice object" is an object juiced by juice juice. For example, fruits and vegetables may be included, but it is natural that there is no restriction on the kind.

In the following, "crushing" and "juice" "Grinding" means cutting several times by ribs or the like. "Juice" means juice in the juice object is discharged to the outside by compression. Accordingly, "crushed material" should be understood as a juice object which has been cut several times before being juiced. Of course, it should be noted that pressure may be applied at the time of "crushing ", as a matter of course, does not mean that the" crushed product "

Hereinafter, "juice" is a kind of liquid that is crushed and juiced and discharged to a predetermined level to allow juice to pass through the mesh net, and "pulp" is not crushed and juiced enough to pass through the mesh net Means a kind of solid discharged. Of course, it is not completely separated into a liquid and a solid, and as a result, it is possible to distinguish juice and pulp depending on whether or not they pass through a mesh network. That is, the ratio of the juice to the pulp may be changed by changing the size of the pores constituting the mesh network.

The "pulp" may be a residue, or it may be included in the juice to improve texture during drinking. For example, in the case of orange juice, the orange juice may become a juice, and the granules and the like may become pulp. If the user does not drink pulp (i.e., orange grains) with orange juice, However, in case of drinking together, pulp (i.e., orange granules and the like) is discharged together with the juice to be consumed by the user.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1. First Embodiment of the Master Clerk

1 to 2, the overall configuration of a master cradle according to a first embodiment of the present invention will be described.

The master batcher includes a screw 200, a drum 300, a main body 400, and a pretreatment unit 800. The pretreatment unit 800 functions as a lid and pretreats the juice to be fed.

The pretreatment unit 800 is provided with an injection port 130. The user can insert the juice into the inner space of the drum 300 through the injection port 130. [

The screw 200 is connected to a power member (not shown) such as a motor provided inside the main body 400 and cooperates with the drum 300 fixed so as not to rotate so as to crush and juice the juice object .

The screw 200 is provided with a rotary shaft 211 and the lower side of the rotary shaft 211 is connected to the rotary shaft insertion portion of the drum 300 so as to rotate by the rectangular shaft 410 of the body 400.

A predetermined space is formed between the upper part of the screw 200 and the drum 300. When the juice is injected from the injection port 130, the space is reached.

The rib 220 is positioned on the top of the screw 200 and the rib 220 interacts with the drum rib 321 of the inner wall of the drum 300 as the screw 200 rotates, And separated into juice and pulp.

A mesh network 270 is located below the screw 200. The juice and the pulp separated downwardly of the screw 200 flow, and the juice flows through the mesh net 270 to the inside of the screw 200, and the pulp does not pass through the mesh net 270 And flows only outside the screw 200.

The drum 300 is detachably mounted on the main body 400, and the screw 200 is rotatably fixed to the inner space.

The bottom surface of the drum 300 is provided with a radially outer first guide groove and a radially inner second guide groove which are separated by the inflow preventing ribs. Accordingly, the juice flowing inside the screw 200 flows along the second guide groove, and the pulp flowing outside the screw 200 flows along the first guide groove.

The pulp flowing along the first guide groove is discharged to the outside through the first discharge portion 340 on the side of the drum 300. The juice flowing along the second guide groove is discharged from the other side of the drum 300 2 discharging unit 360. [0053]

The main body 400 supports the drum 300 and is connected to an external power source.

A power member (not shown) is mounted inside the main body 400 and provides a rotational force to the screw 200 through the prismatic shaft 410 when power is applied from an external power source.

A drum support 430 is disposed at one side of the main body 400 and extends toward the upper end of the main body 400 so that one side of the drum 300 can be contacted.

The preprocessing unit 800 will be described in more detail with reference to FIGS. 3 and 4. FIG.

The pretreatment unit 800 according to the present invention is provided with an upper cutter 811 and a lower cutter 821. The upper cutter 811 and the lower cutter 821 perform relative cutting operations such as scissors. The configuration of the scissors type preprocessing unit is possible in such a manner that the rotational speeds of the upper cutter 811 and the lower cutter 821 are different, or only one of them is rotated and the other is fixed.

The pretreatment unit 800 includes a hopper 810 that is fixedly positioned when the screw 200 rotates and a cutting module 810 that is rotated together with the screw 200 and is located below the hopper 810. [ And a screw seat 830 which is rotated together with the screw 200 and is connected to the cutting module 820.

The hopper 810 is provided with an upper cutter 811. The upper cutter 811 and the hopper 810 are fixed when the screw 200 rotates.

The rotation shaft 211 of the screw 200 is rotatably inserted into the shaft hole 819 at the center of the hopper 810. It is possible to fix the hopper 810 in the correct position even during the rotation of the screw 200 and to easily separate and clean the user.

The hopper 810 includes a first injection space portion 817 through which the juice object passes. The injection port 130 on the upper side of the pretreatment unit 800 communicates with the first injection space portion 817, and the object to be juiced passes.

A blade portion of the upper cutter 811 protrudes on the first injection space portion 817.

As shown in Fig. 3, the blade portion of the upper cutter 811 protrudes radially inwardly in the rotating direction of the screw 200 (counterclockwise in Fig. 3). 4, the middle portion of the juice object is first cut by the upper cutter 811 rather than the outer portion, so that the load of the power member (not shown) provided on the main body 400 can be reduced .

The cutting module 820 is provided with a lower cutter 821. When the screw 200 is rotated, the lower cutter 821 and the cutting module 820 rotate together.

An intermediate shaft insertion portion 829 through which the rotary shaft 211 of the screw 200 passes is located at the center of the cutting module 820.

The cutting module 820 includes a second injection space portion 827 through which the juice object passes.

And the blade portion of the lower cutter 821 is positioned on the second injection space portion 827.

In the state where the upper cutter 811 is fixed, the lower cutter 821 rotates together with the screw 200, so that the juice object is cut like scissors.

The screw seat part 830 includes a third injection space part 837 connected to the second injection space part 827.

A screw (200) is seated on the lower surface of the screw seat (830).

The uppermost rib seat 838 on which the uppermost rib of the rib 220 of the screw 200 is seated is positioned on the lower surface of the screw seat 830. As shown in FIG. 3, both sides of the uppermost rib seat 838 are protrusions whose ribs 220 of the screw 200 are shaped.

When the screw 200 is rotated by the uppermost rib seat portion 838, the screw seating portion 830 rotates naturally and the cutting module 820 connected thereto rotates and rotates to the lower cutter 822 .

It is not necessary to provide a separate structure for connecting the pretreatment unit 800 and the screw 200 to each other so that the hopper of the pretreatment unit 800 is not required, (810), the cutting module (820), and the screw seat (830) are easily separated and cleaned.

A lower shaft insertion portion 839 through which the rotary shaft 211 of the screw 200 passes is located at the center of the screw seat portion 830.

The rotation shaft 211 passes through the lower shaft insertion portion 839 of the screw seating portion 830 and the intermediate shaft insertion portion 829 of the cutting module 820 from below to the upper end of the hopper 810 And is rotatably connected to the shaft hole 819.

The juicing process using the jujube according to the present invention will be described.

The user turns the screw 200 by operating the main wand and injects the juice into the injection port 130.

And passes through the first injection space portion 817 of the hopper 810 fixed in the process of moving the juice object downward toward the drum 300. The cutting module 820 is rotated just below the first injection space part 817. At this time, the object to be juiced is pre-cut by the scissoring action of the rotating lower cutter 821 and the fixed upper cutter 811. If only one cutter is provided, cutting is not performed well or the user has to push it by force as described in the related art, but the cutting effect is excellent due to the scissors of the present invention.

The pre-cut juice object passes through the second injection space part 827 and the third injection space part 837 and reaches the inner space of the drum 300.

On the inner side of the drum 300, the juice is formed by the interaction between the rib 220 of the screw 200 and the inner wall surface of the drum 300 and the drum rib 321, and the juice object is divided into pulp and juice.

The separated juice flows through the mesh net 270 of the screw 200 to the space inside the screw 200, and the pulp does not pass through the mesh net 270 and falls. At this time, the pulp is pulp cut in the pretreatment unit 800, so that even when the leaves are charged, there is no fibrous material having a long length.

The pulp is discharged to the outside through the first discharge portion 340 and the juice is discharged to the outside through the second discharge portion 360.

This preprocessor can be applied to any type of master.

As shown in FIGS. 1 and 2, the mesh drum 270 is located between the screw 200 and the drum 300 (not shown) as well as the master cylinder having the mesh network 270 below the screw 200 (Korean National Publication No. 2012-0029638).

2. Second Embodiment of the Master Clerk

5 to 7, a description will be given of a master clerk according to a second embodiment of the present invention.

As shown in FIG. 5, the master clerk according to the second embodiment includes a hopper 810A, a screw 200A, a pre-processing unit 800A, a drum 300, and a main body 400. As shown in FIG.

Here, the drum 300 and the main body 400 are not different from those provided in the first embodiment described above, and a description thereof will be omitted.

6, the pretreatment unit 800A includes a hopper cutting edge 142 provided in the hopper 810A and screw cutting blades 291 and 292 provided in the screw 200A.

The hopper cutting edge 142 is formed at the outlet 140 of the hopper 810A.

The discharge port 140 of the hopper 810A has a generally elliptical perimeter, and a hopper cutting edge 142 is formed on either end of both ends thereof.

The screw cutting blades 291 and 292 are formed on the upper end surface 280 of the screw 200A.

The upper end surface 280 of the screw 200A is formed as a generally horizontal plane and includes first and second horizontal surfaces 281 and 282 of the same shape arranged symmetrically with respect to the screw rotation axis 211. The skew cutting blades 291 and 292 are formed on the first and second horizontal surfaces 281 and 282, respectively, and more specifically, on the half of the peripheral edges of the respective horizontal surfaces 281 and 282.

In this manner, the screw cutting blades 291 and 292 are formed at two positions on the top surface 280 of the screw 200A, so that the cutting operation is performed twice during one rotation of the screw 200A.

The hopper cutting edge 142 and the screw cutting edges 291 and 292 have sawtooth shapes, respectively. The hopper cutting edge 142 and the screw cutting edges 291 and 292 are in a formally matching relationship with each other. In other words, the hopper cutting edge 142 and the screw cutting edges 291 and 292 have a slight difference in height on the position plane so that they do not actually mesh with each other during the cutting process. However, if they are placed on the same plane, .

Referring to FIG. 7, the juicing process using the jujube seeder according to the second embodiment will be described.

When the user inserts the juice into the injection port 130 while rotating the screw 200A through the operation of the hopper 810A, the hopper cutting blade 142 and the screw cutting blade 291, and 292), the juice object is pre-cut.

At this time, since the hopper cutting edge 142 and the screw cutting edges 291 and 292 interact with each other, a shearing force is applied to the juice object located therebetween, so that the pre-processing cutting can be effectively performed on the juice object.

Since the hopper cutting edge 142 and the screw cutting edges 291 and 292 are formed in a saw-tooth shape instead of a straight general cutting edge shape, when the user's hand touches the hopper cutting edge 142 or the screw cutting edge 291, 292), the possibility of injury is reduced, and the degree of injury can be minimized.

While the present invention has been described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims. It will be appreciated that embodiments are possible. Accordingly, the scope of protection of the present invention should be determined by the claims.
