Description

A juicer comprising < RTI ID = 0.0 > micro holes < / RTI &

More particularly, the present invention relates to a chucker which is provided between a drum and a screw to be ejected and a fine hole is formed in the hook to divide the juice into pulp.

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 this conventional system, the core function of the juice is a mesh network made of stainless steel. The mesh network separates the juice and pulp by passing only the juice through the pulp.

However, when the object to be juiced includes long fibers such as leaves, a hole occasionally occurs in the mesh net made of stainless steel. In addition, since the mesh net must be separately manufactured by stainless steel or the like, then bent into a cylindrical shape and then mounted on a separately injected net drum or screw, the manufacturing difficulty and manufacturing cost increase.

In addition, there is a disadvantage that it is difficult to implement a side discharge method in which the pulp amount can be adjusted and the juice can be re-extracted from the pulp in the case of the type master cylinder adopting the network drum.

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, the present invention will be described in more detail with reference to the drawings.

The overall shape of the master cylinder will be described with reference to Figs. 1, 2 and 5, which is a sectional view thereof.

The main stand includes a lid 100, a screw 200, a drum 300, a main body 400 and a latching part 700. The latching part 700 is a part including a fine hole for filtering the pulp.

The lid 100 is provided with an injection port 130 through which the user can insert the object of juice into the inner space of the drum 300.

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 rotating shaft 270 and the lower side of the rotating shaft 270 is connected through the shaft inserting hole 370 of the drum 300 to rotate by the prismatic shaft 410 of the main body 400.

A predetermined space is formed between the screw 200 and the drum 300 and a space between the screw 200 and the engaging portion 700. When the juice is inserted from the injection port 130, It is.

The rib 220 is positioned in the screw 200 and the rib 220 interacts with the engaging rib 716 of the engaging portion 700 as the screw 200 rotates to cut and grind the juice object, Separate into water and pulp.

The separated juice flows through the catching part 700 and radially outward in the drum 300. The pulp does not pass through the catching part 700, And flows downward from the inside of the portion 700.

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 inner first guide groove 330 and a radially outer second guide groove 350 which are separated by a lower member 720 of the engaging part 700 Reference). Accordingly, the pulp flowing inside the latching portion 700 flows along the first guide groove 330, and the pulp flowing outside the latching portion 700 flows along the second guide groove 350.

The pulp flowing along the first guide groove 330 is discharged to the outside through the first discharge portion 340 on the side of the drum 300 and the juice flowing along the second guide groove 350 is discharged from the drum 300 Through the second discharging portion 360 on the other side of the discharge opening 360. [

A discharge connection portion 322 extending upward is formed on an inner lower surface (an extended surface of the first guide groove 330) below the side wall where the first discharge portion 340 is located in the inner lower surface of the drum 300 Located. The discharge connection portion 322 is located inside the discharge portion connection space 729 of the lower member 720 of the latch portion 700 and the discharge projection portion 323 at the end of the discharge connection portion 322 is located inside the upper base portion 711, So that the engaging portion 700 is firmly engaged with the drum 300. The hooking unit 700 will be described once again.

An axial insertion hole 370 is located at the center of the drum 300. The rotation axis 270 of the screw 200 is inserted into the shaft insertion hole 370. [ 3, the shaft insertion hole 370 is an opening located at the center of the cylindrical member, and on the upper surface of such a cylindrical member, two projections are positioned so as to enable double sealing. Due to this double sealing structure, the pulp does not flow into the shaft insertion hole 370 and the pressure of the first discharge portion 340 and the second discharge portion 360 is freely controlled, so that the pressure for juicing increases The juice rate increases.

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 engaging portion 700 is located between the screw 200 and the drum 300 and forms a fine hole therebetween by the engagement of the upper member 710 and the lower member 720.

That is, the juice object is divided into juice and pulp by the interaction of the rotating screw 200 and the fixed engaging part 700, and the separated juice passes through the fine holes. The pulp that has not passed through the fine holes is discharged to the first discharge portion 340 and the juice that has passed through the fine holes is discharged to the second discharge portion 360.

The upper member 710 includes an upper base portion 711, a plurality of upper connecting portions 712, a plurality of projections 713, a seating portion 715, a locking rib 716, Hour).

The upper base portion 711 is circular and a plurality of upper connecting portions 712 extend downward in the radial direction of the upper base portion 711. [

A plurality of protrusions 713 are provided at one end of each of the upper connection portions 712. The plurality of protrusions 713 are inserted into the insertion holes 724 located in the lower base portion 721 of the lower member 720 so that the upper member 710 is tightly bound to the lower member 720.

When viewed in the radial direction of the upper base portion 711, the upper connecting portion 712 and the lower connecting portion 722 are staggered. Accordingly, when the upper member 710 and the lower member 720 are connected, the upper connecting portion 712 and the lower connecting portion 722 are alternately arranged.

A fine hole is formed between the upper connecting portion 712 and the lower connecting portion 722 which are alternately arranged and alternately arranged. In other words, the shape and size of the upper connecting portion 712 and the lower connecting portion 722 are determined so that fine holes are generated.

The fine holes created here pass only the juice without passing the pulp through. Therefore, when the juice object is separated into the juice and pulp by the interaction between the rotating screw 200 and the later-described latching rib 716, the juice passing through the minute holes of the latching part 700 is separated from the catching part 700, The pulp that does not pass through the fine holes of the latching part 700 flows downward because the pulp does not pass through the latching part 700, whereby the juice and the pulp are separated.

The juice which has passed through the fine holes flows through the second guide groove 350 radially outward of the inner lower surface of the drum 300 and is discharged through the second discharge portion 360. The pulp that has not passed through the fine holes flows through the first guide groove 330 radially inward of the inner lower surface of the drum 300 and is discharged through the first discharge portion 340.

A seating portion 715 is located on the upper side of the upper base portion 711. The lid 100 is engaged with the seating portion 715 and the upper edge of the drum 300 to help secure the locking portion 700.

The engaging rib 716 is a member protruding inward of the upper member 710 and interacts with the rotating screw 200 and the rib 220 to juice the juice object.

The engaging rib 716 may be provided on the lower connecting portion 722 of the lower member 720 instead of the upper member 710 or on both the upper connecting portion 712 and the lower connecting portion 722. [

The lower member 720 includes a lower base portion 721, a plurality of lower connecting portions 722, a plurality of protruding portions 723, and an insertion hole 724.

The lower base portion 721 is circular and has a circular shape in which the discharge portion connecting space 729 is located radially at a predetermined angle. That is, the lower connection portion 722 is located only in the region except the discharge portion connection space 729 in the radial direction.

The lower connecting portion 722 has a shape similar to that of the upper connecting portion 712 and extends upward from the lower base portion 721 and has a protruding portion 723 at one end thereof. Is inserted into an insertion hole (not shown).

And the discharge connection portion 322 of the drum 300 is positioned in the discharge portion connection space 729.

That is, the discharge connection portion 322 is located on the inner lower surface of the inner lower surface of the drum 300 below the side wall where the first discharge portion 340 is located. The discharge connection portion 322 has a shape similar to that of the lower connection portion 722, When the member 720 is coupled to the drum 300, the discharge connection portion 322 is connected to the upper base portion 711.

To this end, the discharge connection portion 322 also extends upward and has a discharge protrusion 323 at its end, and the discharge protrusion 323 is connected to an insertion hole (not shown) of the upper member 710.

Through this structure, the locking part 700 is more firmly coupled to the drum 300, while the radially inner first guide groove 330 is not connected to the second guide groove 350, And is connected to the first discharge portion 340 on the outer side.

Meanwhile, it is preferable that the upper member 710 and the lower member 720 are integrally injection-molded. That is, a separate mesh network made of stainless steel or the like is not required, and the upper and lower members 710 and 720 are injection-molded and assembled with other molded products, thus making it possible to manufacture a joystick easily and cost-effectively.

It is possible to realize a fine hole only by combining two members without adopting a mesh network made of stainless steel.

Due to the stainless steel material, the mesh holes of the mesh net can be clogged due to long fibers, which are not cut, but the phenomenon is less because the fine holes between the two members are injection materials.

Further, when fibers and the like are sandwiched in the mesh net and the mesh hole made of stainless steel, the user is difficult to clean. Separate cleaning tools such as brushes should be used. If they are used tightly, they can not be removed well. However, even if the fibers are sandwiched between the upper member 710 and the lower member 720, the user can naturally discharge the fibers at the moment when the upper member 710 and the lower member 720 are separated from each other So that the removal is easy.

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.
