DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a squeezing machine capable of adjusting a squeezing pressure, more specifically, a squeezing machine capable of adjusting a squeezing pressure by moving a pressure tube in an axial direction.
More particularly, the present invention relates to a juicer capable of performing a grinding operation by exchanging some parts.

[0002]

2. Description of the Related Art Generally, mixers used in kitchens are:
The input food is finely ground through rotation of a metal screw provided at a lower portion. The pulverized food and drink from the mixer contains not only fiber but also juice. In order to extract only juice from such a mixer, it is necessary to filter fibers and other wastes with a net. In the case of a fruit having a high water content, the juice can be extracted using the net as described above, but it has disadvantages that the net must be used and the juice cannot be completely extracted. There is also a disadvantage that juice cannot be extracted properly when the content of fiber is high like vegetables. Further, when extraction is performed using a mixer, the lower blade must be cleaned after use.

[0003] Therefore, a special juice extractor is used to extract the juice. Such juicers are roughly divided into two types: a method using centrifugal force and a method using pulverization using a screw. Among them, the use of a screw is an excellent method in terms of the efficiency of extracting juice. For example, U.S. Pat. No. 5,452,650 discloses a technique for grinding vegetables and fruits while passing them between a pair of helical screws. Although the method using the helical gear has the advantage of improving the extraction efficiency, there is a problem that heavy metal powder flows from the gear due to interference between the two helical gears.

[0004] The applicant of the present invention filed a Korean Patent Office on March 3, 1993 with the Korean Patent Office for a juice extractor which solved such problems with the helical screw type juice extractor. Patented. In Korean Patent No. 100552, the applicant used one screw instead of using a helical screw. The housing surrounding the screw is provided with a cutting blade having a triangular axial cross section. The screw is provided with a spring at an end connected to the motor, and the screw is assembled while applying a predetermined pressure to the housing in the forward direction.

[0005] The above patent discloses that the input workpiece can be cut while moving along the screw, and that the housing and the front end of the screw are connected so that an excessive load is not applied to the motor due to the amount of the input workpiece. We proposed a newer juicer than before, in that it cuts the input workpiece while the gap changes.

Further, the applicant of the present application filed an application for registration of a utility model with the Korean Patent Office on August 18, 1998 for the technology improved from Korean Patent No. 100552, and received a registration of a Korean utility model on No. 97323. Was. Patent No. 97323 in Korea Utility Model Registration
The amount of juice leaking toward the outlet was reduced by covering the front end of the screw with a rubber ring on the outlet side in No. 2.

[0007] The applicant of the present application filed Korean Patent No. 100552.
No. 97323 was filed with the Korean Patent Office on the same date as Utility Model Registration No. 97323, and was registered under Korean Utility Model Registration No. 97322. In Utility Model Registration No. 97322, a replaceable cover was adopted so that the above-mentioned juice extractor could be used for a grinder. This focuses on the fact that there is a difference only in whether the juice extractor and the crusher cut the work to be put in and separate the juice, or discharge without separating the juice and the work. Instead of removing the net of the machine cover, we designed a crusher integrally formed without gaps. This technology extends the use of patent 100552 to crushers. Hereinafter, a device that can perform juice and grinding together will be referred to as a grinding extractor.

[0008] Further, the applicant of the present application filed a utility model registration application with the Korean Patent Office with respect to the technology obtained by improving the above-mentioned pulverizing and squeezing machine on December 9, 1994, and received a utility model registration on No. 110589. Was. In this utility model, instead of inserting a spring between the screw and the gear of Korean Patent No. 100552, a hollow cylinder for pressing the screw at the front end of the screw was provided. In front of this cylinder is a rotatable knob, which is fixed to the housing and can be moved axially by rotation.
nob) is provided. A hole is formed in the center of the rotary knob, and the cylinder is inserted into the hole. A spring is provided between the rotary knob and the cylinder, and the spring applies a different pressure to the front end of the screw depending on the axial position of the rotary knob.

Therefore, the pressure can be varied depending on the type of the work put into the crushing and squeezing machine, and the same work put into the squeezer can be processed in various ways.

[0010] The applicant of the present application filed a utility model application with the Korean Patent Office on July 1, 1995 for the above-mentioned improved matter of Korean Utility Model Registration No. 110589 so as to be easily assembled and disassembled. No. 121072 received utility model registration. In the present technology, a rubber ring is provided as in the aforementioned Utility Model No. 97323.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a crushing and squeezing machine which can cut a work to be fed into the crushing and squeezing machine more finely.

It is a further object of the present invention to provide a crushing and squeezing machine which can be easily assembled and disassembled and whose interior can be easily cleaned.

[0013]

In order to achieve the above object, a crushing and squeezing machine according to the present invention comprises: a screw having an inclined front end; a housing for housing the screw; a space between the screw and the housing. Provided in the cutting cylinder having a cutting blade on its inner surface which is cut in cooperation with the screw and gradually lowers toward the front end direction of the screw; in the axial direction of the screw on the front side of the front end of the screw It is installed so as to be movable, and closes the front end of the screw in contact with the front end when it is completely moved in the direction of the front end of the screw,
Closing means which provides a passage between the screw and the front end of the screw when moved in a direction opposite to the screw front end; and elastic means for applying force to pressurize the front end of the screw.

In addition, in order to achieve the above-mentioned object, a crushing and squeezing machine according to the present invention comprises a main body equipped with a motor, a gear train (train gear) and an operation switch; a transfer unit for transferring an input workpiece; A first cutting unit installed in front of the transfer unit for transferring a workpiece while cutting the same with the cutting blade; a second cutting unit provided in front of the first cutting unit and installed at a smaller interval than the blade of the first cutting unit; A cutting portion, a screw provided in front of the second cutting portion and having a third cutting portion further inclined toward the axis of the screw than the second cutting portion; a passage for feeding a workpiece, and discharging juice A housing having a lower hole and a rear projection protruding outwardly; a ring for locking the projection of the housing when rotated to fix the housing to the main body; A truncated cone-shaped cutting cylinder, which is provided between the housing and the housing and has on its inner surface a cutting blade which is cut together with the screw and gradually lowers toward the front end of the screw; a circular hole is formed in the front side and the housing is A wall provided with a radial blade on the surface facing the rear, a plurality of protrusions extending to the rear side of the wall and fixing the cover to the housing are provided on the rear side, and can be grasped by a human hand.

As in the above-described technique, the present invention is also disclosed in the tenth patent.
The technical ideas of No. 0552 and Utility Model Registration No. 110589 are used. That is, when the screw is moved in the axial direction, or when the closing means installed at the front side of the screw and forming a gap with the screw is moved in the axial direction of the screw, the pressure applied to the front side of the screw and the processing transferred by the screw It utilizes the principle that the gap changes depending on the pressure of the object.

The crushing and squeezing machine according to the present invention can be largely separated into a main body and other parts. The main body includes a power supply, a motor and a gear train (gear trai-n). As a component of such a main body, a known device can be used. It is desirable that the power supply of the main body is designed to be used at various voltages.

The motor and gear train should be designed so as not to cause scratches when operating the squeezer.
If the output of the motor is sufficient, the reduction ratio of the gear train can be reduced and the working speed can be increased, but if the motor output is weak, the reduction ratio of the gear train should be increased to the extent that the motor is not damaged. .

According to the invention, one of the housings is open,
The screw and the cutting cylinder can be inserted there. The housing is provided with an input port for inputting a workpiece to be crushed or squeezed and an outlet for discharging extracted juice.

For convenience of use, the inlet is preferably provided at an upper portion of the housing, and the outlet for discharging juice is preferably provided at a lower portion of the housing.

Preferably, the body is provided with fixing means for assembling the housing. Preferably, the fixing means is a projection protruding from the housing, the projection being connected to the body by means of a ring. It is desirable to simplify the internal structure of the housing as much as possible so that it can be easily cleaned.

A screw is provided in the housing.
The screw has a function of transferring a workpiece put into the housing and a function of cutting the loaded workpiece.
It is important to note the fact that the screw requires a guide to transfer the workpiece. That is, in order for the screw to continuously transfer the transferred workpiece in the previous direction, the workpiece must be continuously supplied or the movement of the workpiece must be limited so that the workpiece does not rotate along the screw. Must.

Considering that the feeding of vegetables and the like is stopped when the operation is completed, it is desirable to limit the movement of the workpiece so that the workpiece does not rotate along the screw. Such a role of the guide is achieved by a cutting blade of a cutting cylinder described later.

The screw according to the present invention is preferably a transfer unit for transferring the input workpiece, and a first cutting unit installed in front of the transfer unit for transferring the workpiece while cutting the workpiece with the cutting blade. A second cutting portion installed in front of the first cutting portion and installed at a smaller interval than the blade of the first cutting portion; a second cutting portion installed in front of the second cutting portion and facing the axis of the screw; Third more inclined
The cutting portion has a frusto-conical end portion whose outer diameter gradually decreases in the forward direction. A square shaft (squ
ared shaft). The square shaft is connected to a gear train in the main body and receives power transmitted by a motor.

The cutting cylinder installed between the screw and the housing has a cutting blade on its inner surface. The shape of the cutting blade is important for ensuring fine cutting. Therefore, a cutting blade whose height is gradually reduced toward the front is desirable. More desirably, the height of the cutting blade is substantially zero at the front end of the cutting cylinder. Thus, when the height of the cutting cylinder becomes zero, the size of the particles of the workpiece limited by the height of the cutting cylinder becomes smaller. That is, if the height of the cutting blade is not 0, the size of the work that is theoretically finestly cut even after passing through the cutting cylinder becomes the height of the cutting blade. In order to sequentially grind the workpiece while advancing it along the screw, it is particularly desirable that the cutting blade has a triangular cross section.

The cutting cylinder according to the present invention is roughly divided into a cutting cylinder for grinding and a grinding cylinder for juice. The crushing cylinder is used for extracting juice of fruits and vegetables, and the crushing cylinder is used for grinding meat and the like. The milling cylinder for squeezing must be provided with a net to separate the juice separately, but the milling cylinder for milling does not need to separate the juice separately, so it can be made of an integral plastic without mesh. desirable.

The shape of such a cutting cylinder is desirably frusto-conical to surround the screw. The advantages of using another cutting cylinder instead of providing a cutting blade inside the housing are as follows: First, cleaning after use is convenient. When the cutting blade is inside the housing, the entire inside of the housing must be cleaned, but when a cutting cylinder is separately provided, only the portion where the juice flows can be cleaned.

Second, after the cutting blade is worn or damaged, its replacement is easy. If the cutting blade is worn or damaged, the entire housing with the cutting blade must be replaced if the cutting blade is provided in the housing, but if another cutting cylinder is provided, It is economical because only the cutting cylinder needs to be replaced.

Third, various processing can be performed by changing the cutting cylinder. Changing the cutting cylinder has an advantage in that various processing can be performed without replacing the housing. This is a utility model registration No. 11 without another cutting cylinder
This is one of the differences that distinguishes the present invention from No. 0589. The mesh contained in the cutting cylinder for juice has a large number of perforations (p
erforation) is formed. The cutting cylinder for juice has a main body made of plastic and a net provided on the inner periphery of the main body. At the axial ends of the cutting cylinder for squeezing and the crushing cylinder, mounting means can be provided which can be easily installed and separated from the housing. Such a mounting means may be a flange extending along a circumferential direction. Preferably, the mesh is formed from a metal that is harmless to the human body, such as stainless steel.

The cutting cylinder for squeezing may have a rubber ring at the front to enhance the squeezing effect. Such a rubber ring squeezes the workpiece while covering the front part of the screw, so that the workpiece can be squeezed with stronger pressure. A spring or the like can be used instead of the rubber ring.

In front of the screw transfer section, there are provided cutting sections for transferring the workpiece while cutting the workpiece together with the cutting blade of the cutting cylinder. Such a cutting unit is a first cutting unit installed immediately in front of the transfer unit, and a second cutting unit installed in front of the first cutting unit and installed at a smaller interval than the blade of the first cutting unit. A third cutting portion installed in front of the second cutting portion and inclined further toward the axis of the screw than the second cutting portion. Each of the cutting sections is designed so as to conform to the shape of a housing portion or a cover which performs a cutting operation together with the cutting section and the like.

It is desirable that the first cutting portion is usually made of three or more screws. The second cutting part is the first
It starts from the part where the thread of the cutting part ends. The second cutting part may be divided into a thread extending from the screw of the first cutting part and a newly starting thread at a uniform interval. Such a thread of the second cutting portion cuts the workpiece cut and transferred by the first cutting portion more finely. The third cutting section can be installed before the second cutting section where the screw has a relatively steep angle and the outer diameter of the screw decreases. Preferably, the third cutting portion has the same number of threads as the first cutting portion described above. The third cutting section performs the final cutting work of the workpiece together with the cutting blade installed on the inner surface of the cover as described below.

[0032] Finally, it is desirable that the end of the screw provided before the third cutting portion has a shape capable of contacting the closing means provided at the front portion of the screw. The rear part of the screw must be provided with means for connection to the driving means. Such connecting means include:
Squared shafts are particularly suitable.

In the present invention, it is desirable to provide a cover for closing the opened end of the housing after the screw and the cutting cylinder have been assembled. Preferably, such a cover is designed to be easily assembled by hand.

The cover is preferably rotated or assembled or disassembled by hand with respect to the housing. Various shapes are taken for the housing. The cover particularly preferably consists of a cylindrical part and a wall connected to this cylindrical front part and having a centrally open hole through which a hole can be passed axially. An inclined cutting blade can be provided on the surface of the wall facing the screw so that the cutting blade can be cut together with the screw. Desirably, the inclination of the cutting blade of the cover toward the axis of the screw is the same as the inclination of the third cutting portion toward the axis of the screw.

Preferably, the cover is provided with a means that can be easily assembled or separated from the housing.

An axial plunge extending in the axial direction is particularly suitable as such an assembly means. Preferably, the cover is configured to receive the closing means. For such applications, the walls of the cover can be provided with inclined ribs. The inclined ribs are inclined by a predetermined angle with respect to the axis of the screw, and can move in the axial direction when the closing means can be rotated as described below.

As the closing means, any means for closing the screw while pressing it in the axial direction can be used. Such a closure may also provide a pressure regulator for regulating the pressure on the screw. The closing means contacts the front end of the screw while applying pressure to the screw in the axial direction, but when the workpiece transferred from the screw presses the closing means with a predetermined pressure, the distance between the closing means and the screw increases, and Is discharged into the gap between the closing means and the screw. At this time, the gap between the screw and the closing means varies depending on the setting of the pressure adjusting device.

Such a closing means is empty at the center,
The outer diameter of one end may be a cylinder having a step formed thereon. Desirably, the stepped cylindrical portion contacts the end of the screw. A pressure-regulating device that is particularly adapted for a cylindrical closure means with an open center is a resilient rubber ring and a rotary knob that limits the movement of the rubber ring. The rubber ring may be installed between the rotation knob connected to the inclined rib of the cover and the step. When the rotation knob rotates in the axial direction, it can move forward or backward in the axial direction along the inclined rib. The rotary knob can also be grooved around its circumference so that it can be rotated by hand. With the present invention, one must not miss the fact that the workpiece is ejected through the center of the closure. When exiting through the center, various cross-section workpieces can be created by changing the shape of the cylindrical front hole.

At this time, the gap between the rotary knob (100) and the cylindrical step (81) or the gap (L1) between the rotary knob (100) and the cover (65) is maximized, and the rubber ring (90 ) Is minimally compressed. Thus, it should be noted that the rubber ring (90) applies pressure so that the cylinder (80) contacts the end (39) of the screw even when the rubber ring is minimally compressed. . Thus, it is important to always apply pressure in order to prevent the workpiece from being discharged without receiving any pressure.

FIG. 12 illustrates a state in which the rotary knob (100) has moved to the right to the maximum so that the operating pressure is maximized.
In this case, the distance between the rotary knob (100) and the cylindrical step (81) or the gap (L1: L1> L2) between the rotary knob (100) and the cover (65) is minimized, and the rubber ring (90 ) Is compressed to the maximum.

As described above, when the rotary knob (100) is moved between the positions shown in FIGS. 11 and 12, various pressures can be applied to the workpiece. For example, when it is desirable to squeeze at a low pressure like a fruit, FIG.
While the juice is squeezed in a state as shown in FIG. 12, when it is desirable to squeeze the juice at a high pressure like a vegetable, the juice is squeezed in a state as shown in FIG. The rotary knob is also used for grinding.
By rotating (100), the size of the particles to be pulverized can be adjusted.

The assembling sequence for the embodiment of the juice grinder according to the present invention will be described as follows. Retaining ring (1
27) is rotated to fix the housing (1) to the main body. The screw (30) is pushed in a squared shaft, and the square shaft is connected to the gear (123).
