Description

Juicer with improved juice performance

The present invention relates to a juicer, and more particularly to a juicer with improved juice performance that can be used for the juice of a variety of materials, such as seeds, such as sesame seeds, perilla, as well as vegetables, fruits without replacement of the housing.

Juicer is a device for extracting juice by compressing the juice material such as vegetables, seeds (eg sesame, perilla), there is a centrifugal method and a double gear method. The centrifugal separation method is suitable for extracting fruit juices, but has a problem in the juice of juice materials such as vegetables, sesame seeds, and sesame seeds, which are high in fiber and low in moisture. On the other hand, the twin gear method is to extract the juice by cutting and compressing the juice material or compressing at the same time with the cutting process, and the juice extraction rate is several times higher than that of the centrifugal separation method. Juicer is occupied.

Such a pair gear type juicer includes a pair of grinding roller parts in the form of a helical gear and a pair of juice roller parts in an Archimedes spiral shape, and the grinding roller part and the juice roller part are formed in a housing. It is made by fastening through the fastening part in the drive unit after being housed in. The pair of grinding rollers are driven by a driving unit to rotate with each other, to crush and feed the introduced materials to the juice roller unit while crushing the juice, and the juice roller unit is compressed from the juice material by pressing together with the housing while transferring the crushed material. Extract the juice.

1 and 2, a conventional juicer is connected to the juicer 200 to drive the juicer 200 and the drive unit 100, and connected to the drive unit 100 It is driven by the juice portion 200 to extract the juice by driving the crushing the juice material, and the fastening portion 300 for detachably coupling the drive unit 100 and the juice unit 200.

The drive unit 100 is provided with a motor 150 to the inside, the motor housing 110 having a hollow first connecting portion 130 protruding forward, and protrudes forward through the first connecting portion 130. The rotating shaft 170 is driven by the motor 150, and the fixed shaft 190 protruded in parallel with the rotating shaft 170.

The juice part 200 is composed of a roller portion connected to the drive unit 100, the hollow housing 200a is accommodated in the roller unit and coupled to the motor housing 110 of the drive unit 100. The roller part is composed of a grinding roller part 250 and a juice roller part 260 connected to the front of the grinding roller part 250 and extended to decrease in diameter toward the front. The roller unit is accommodated in the housing 200a to pulverize the juice material while rotating, and serves to transfer the juice while pressing. The housing 200a has a plate-shaped second connection portion 221 extending in a radial direction from the rear end toward the driving unit 100 and inclined toward the driving unit 100 at an edge thereof.

The grinding roller unit 250 has a grinding blade (helical gear) formed on the outer circumferential surface thereof and rotatably coupled to the first grinding roller 251 and the fixed shaft 190 which are coupled to rotate integrally with the rotary shaft 170. The second grinding roller 255 is made. The grinding blades formed on the outer circumferential surfaces of the first grinding roller 251 and the second grinding roller 255 are provided to be engaged with each other, the grinding blade and the fixed shaft 190 of the first grinding roller 251 coupled to the rotary shaft 170 2) The grinding blades of the second grinding roller 255 coupled to be idling are rotated while being engaged with each other.

Become this

Becomes

Referring to FIGS. 8 and 9, the second juicer 570 is deformed as the pressure generated in the juice process rises to prevent the extraction efficiency from dropping and to make the juice smoothly. The distance d ₂ ratio between the centers to the diameter D ₂ of the area juice hole 567a is greater than the ratio d ₁ between the centers to the diameter D ₁ of the second area juice hole 565a. It is largely formed.

The residual area ratio of the second area 565, which is a value obtained by dividing the remaining area of the second area 565 by the total area of the second area 565, is greater than or equal to the remaining area ratio of the first area 561. In addition, the residual area ratio of the second region 565 is smaller than the residual area ratio of the third region 567 which is a value obtained by dividing the residual area of the third region 567 by the total area of the third region 567. This means that the remaining area of the third region 567 is larger than the remaining areas of the other two regions.

Therefore, by securing the rigidity of the third region 567 of the second juice portion 570, the juice member is moved forward and the juice of the internal pressure generated between the transfer juice portion 560 and the juice roller portion 260 as the juice is juiced. In response to the increase, swelling and deformation of the third region can be prevented, thereby maintaining the juice force.

Meanwhile, the first region juice hole 561a formed in the first region 561 has a diameter in the range of about 0.13 mm to 0.17 mm.

The third region 567 is formed in front of the second region 565. The third region 567 is composed of a plurality of third region juice holes 567a. The third region juice hole 567a is formed with a diameter in the range of approximately 0.13 mm to 0.17 mm. More preferably, the diameter of the third region juice hole 567a forms 0.15 mm. The spaced distance of the center of the third region juice hole 567a is approximately 1.4 mm to 1.8 mm. More preferably, the distance between the centers of the third region juice holes 567a is 1.4 mm.

As shown in FIG. 10, the first region juice hole 561a formed in the first region 561 is formed to have a radial outer diameter w and an inner diameter n different from each other. In the first region juice hole 561a, a diameter w of a radially outer side is larger than a diameter n of an inner side thereof. The radially outer diameter w is formed in the range of 0.27 mm to 0.33 mm. Preferably the diameter (w) of the radially outer side is preferably formed to 0.3mm.
