Description

[Detailed Description of the Invention] The present invention relates to a so-called juicer that shreds fruits, vegetables, etc. and extracts only their juice.

Juicers commonly available on the market come in a variety of configurations; examples include the following:

That is, a basket equipped with a scraping cutter at the bottom of a cylindrical filter is connected to a motor-driven spindle protruding from the bottom of the container, and the basket is suspended from the bottom surface of the lid attached to the top opening of the container. The material (fruit, etc.) is pushed through the material input tube, the material is shredded by a scraping cutter rotated by a spindle, and the shredded material is separated into fruit juice and liquid through a filter. It is.

A juicer with this structure has fewer parts and is more compact than a juicer that uses a mortar-shaped basket and shakes out the waste into a doughnut-shaped waste receiver provided on the outer periphery of the basket. It is advantageous.

However, a juicer having such a structure has a problem in that as the dregs adhere to the inner surface of the filter, the thickness of the dregs increases, and the extraction rate (ie, squeezing rate) of the fruit juice decreases.

In addition, since the scraping cutter is installed on the inner bottom of the basket, as more material is added, new shredded material pushes up the scum that has adhered to the inner surface of the filter, and in addition to this, the adhesion of the scum is becomes non-uniform in the circumferential direction of the filter.

The non-uniform adhesion of crumbs causes the basket to rotate in a mortar-like manner due to eccentricity, resulting in unnecessary vibrations.

Therefore, the present invention has a structure that can even out the residue adhering to the filter, and also has a structure that allows the thickness of the adhesion to be adjusted arbitrarily, thereby preventing unnecessary vibrations and making it possible to remove adhering residue as appropriate. The purpose of the present invention is to provide a juicer with an improved extraction rate.

The main feature of this invention is that a scraping rib is provided near the material input cylinder to scrape off the debris adhering to the inner circumferential surface of the filter, and at the same time equalize the distribution of debris adhesion.In addition, this rib can be rotated. It is possible to freely adjust the thickness of adhering debris,
In addition, the structure is such that the material input cylinder can be easily taken in and out when the lid is attached or removed.

The present invention will be described in detail below based on illustrative embodiments.

FIG. 1 shows a cross-sectional view of the overall structure of a juicer according to the present invention.

This juicer can be roughly divided into a base 1, a container 2 that is removably placed on the base 1, a basket 3 that is housed in the container 2, and a charging cylinder 4 that inserts materials into the basket 3. It is divided into a lid 5 and a lid 5.

The base 1 has a generally oval shape in cross section, and a spindle 7 is vertically protruded from its horizontal portion, that is, the mounting table 6.

On the other hand, a motor 8 is provided inside the vertical portion of the base 1.

The rotation of the motor 8 is transmitted via a pulley 9 on the motor rotation shaft, a belt 10, and a pulley 11 on the spindle.
This causes the spindle I to rotate.

The container 2 has a bottomed cylindrical shape with an open upper end, and a cylindrical wall 12 surrounding a spindle 7 is provided upright at the center of the bottom.

The basket 3 also has a bottomed cylindrical shape with an open upper end.

A cylindrical shaft 1 extending vertically is provided on the lower surface of the bottom of the basket 3.
3 is installed protrudingly.

This cylindrical shaft 13 is fitted into the spindle 7 in such a manner that rotation is prevented so that the basket 3 rotates together with the spindle 7.

A material scraping cutter 14 is provided on the upper surface of the bottom of the basket 3.
is installed.

Further, a cylindrical filter 15 is mounted inside the basket 3 with an appropriate gap spaced from the inner peripheral surface thereof.

A return ring 16 is provided on the inner circumference of the upper end of the filter 15 to prevent the debris attached to the filter 15 from rising.

Note that this basket 3 is removably attached to the spindle 7.

The lid 5 is removably placed over the upper end of the container 2.

As shown in FIG. 3, on the lower surface of the lid 5, there is provided a material input cylinder 4 which is eccentric in relation to the rotational axis of the spindle 7 and has a horizontal cross-section that hangs down toward the scraping cutter 14. .

Naturally, this material input cylinder 4 penetrates in the axial direction.

A waste catcher 17 is provided at the lower end of the material input tube 4 and extends in a direction opposite to the eccentric direction of the input tube 4.

Furthermore, as shown in FIGS. 2 and 3, a scraping rib 18 is provided on one side of the material input cylinder 4.

As can be seen from FIGS. 2 and 3, the scraping rib 18 is rotatably supported in the horizontal direction by having the upper end of the base shaft 19 pivoted to the lid 5 and the lower end pivoted to the scrap receiving part 17. has been done.

The upper end of the base shaft 19 passes through the lid 5, and a knob 20 for adjusting the rotation angle of the scraping rib 18 is provided at the tip.

By turning this knob 20, the angle of the scraping rib 18 with respect to the inner surface of the filter 15 can be freely changed to an acute angle or an obtuse angle.

Further, as shown in FIG. 4, grooves 22 are carved in predetermined angle units on the upper surface of the bearing 21 of the lid 5, which faces the lower surface of the knob 20. engages and locks the scraping rib 18 at each predetermined angle.

Then, when the scraping rib 18 rotates to a certain extent, the stopper 2
3 and cannot rotate any further.

By making the scraping rib 18 movable in this manner, the scraping rib 18 is caught on the return ring 16 of the filter 15 when the lid 5 is opened and the waste receiving portion 17 is taken out from the filter 15 together with the material input cylinder 4. It can be easily taken out without any problems.

Next, the effect will be explained.

When making fruit juice or the like, the motor 8 is driven and the material such as fruit is pushed into the material input tube 4 by the piston 24.

Then, the material is sequentially shredded by the scraping cutter 14.

The shredded material is pressed against the inner surface of the filter 15 by centrifugal force.

Therefore, only the fruit juice contained in the shredded material is filtered through the filter 1.
5, and travels upward along the inner surface of the peripheral wall of the basket 3,
It is stored in container 2.

As materials are added one after another, the amount of dregs adhering to the inner surface of the filter 15 gradually increases, but since the scraping ribs 18 are provided, the thickness of the dregs can always be kept uniform.

Therefore, since the adhesion of debris does not specifically clump, the basket 3 does not rotate in a mortar shape, and vibrations can be prevented from occurring.

Further, since the thickness of the dregs does not exceed a certain level due to the action of the scraping ribs 18, the fruit juice valves are not absorbed into the dregs, and the extraction rate (squeezing rate) can be improved.

Further, the scraped scraps are sent inward by the scraping rib 18 in the direction of the arrow shown in the figure,
Therefore, the shredded materials adhering to the filter 15 are always newly scraped off, thereby improving the extraction rate.

In addition, since the scraping rib 18 can be rotated arbitrarily, it is also possible to adjust the thickness of the adhered debris.

As described above, according to the present invention, by providing the scraping rib, it is possible to prevent unnecessary vibrations due to non-uniformity of the particles adhering to the filter, and by providing the residue receiving part, the squeezed particles can be collected sequentially. Coupled with this, the aperture ratio can be improved.

Furthermore, by making the scraping rib movable, the lid can be easily removed when the juicer is disassembled, and the thickness of the adhering residue can be adjusted as desired.
