Description

[Detailed explanation of the idea] This invention relates to a juicer.

Recently, a basket consisting of a scraping cutter placed at the bottom of a cylindrical filter is connected to a spindle that protrudes from the bottom of the container while being connected to a motor, and material is collected from a material input tube formed on a lid attached to the container. There is a type of juicer that uses a filter to separate moisture and waste from the shredded material, and collects the waste on the inner surface of the filter.

This type of juicer has fewer parts and can be made smaller compared to a type of juicer that uses a mortar-shaped basket to shake out waste into a donut-shaped waste receiver installed on the outer periphery of the basket. can.

However, on the other hand, as the residue becomes thicker on the inner surface of the filter, the extraction of liquid content decreases and the squeezing rate deteriorates.

In particular, when the scraping cutter located at the bottom of the filter sequentially shreds the material, the scraps are pushed by the shredded material and rise up the inner surface of the filter.

As described above, if a thick amount of debris adheres to the upper part of the inner surface of the filter, which is far from the bottom surface, the amount of debris adhered to the filter is uneven, which causes the rotational balance to be lost and large vibrations such as mortar movement to occur to occur.

In order to solve this problem, increasing the size of the basket means that the container must also be made thicker.

This idea was created in view of the above points, and aims to improve the squeezing rate without increasing the size of the basket or container, and to create a juicer that can suppress the generation of vibration. It is something.

This idea uses protrusions to scrape off the debris adhering to the inner surface of the filter to regulate the thickness of the adhesion.
The filter improves the ability to extract liquid and increases the squeezing rate without increasing the size of the basket or container, and the protrusions prevent dirt from thickly adhering to the upper part of the inner surface, which is far from the bottom of the filter.
Therefore, the structure is such that it is possible to prevent rotational imbalance from occurring.

An embodiment of this invention will be described based on the drawings.

1 is a base, and the base 2 fixed inside this base 1 has a
A motor 3 and a spindle 7, which rotates about a vertical axis by transmitting the rotation of the motor 3 through a pulley 4.5 and a belt 6, are supported.

Further, a container 8 having an open top is detachably held on the base 1.

A cylindrical wall 9 surrounding the spindle 7 is integrally formed at the center of the bottom of the container 8 .

The basket 10 housed in the container 8 is inserted into the cylindrical wall 9 and placed on a cutter base 12 having a cylindrical shaft 11 that is axially connected to the spindle 7 while being prevented from rotating. A cutter 13 is fixed, and a cylindrical filter 15 is fixed with a small gap (inside) of a peripheral wall 14 rising from the periphery of a cutter stand 12.

A presser ring 16 is formed on the upper edge of the filter 15 and is bent inward to suppress the rising of the aperture scum.

Next, a lid 18 is provided, which is integrally formed with a material input tube 17 having an open lower end that hangs down toward the outer periphery of the scraping cutter 13.

At the lower end of the material input tube 17, a circular waste receiving surface 19 is formed with an enlarged circle concentric with the center of the filter 15, but the material input tube 17 itself is located at a corner of the waste receiving surface 19 and has a cross section. It is a glyph.

Thus, in the space between the inner surface of the filter 15 and the side surface 20 of the material input cylinder 17, a waste storage portion 21 is formed by the side surface 20 and the waste receiving surface 19 to store waste.

A guide ridge 22, which is a protrusion projecting toward the inner surface of the filter 15, is integrally formed on the side edge of the material input cylinder 1γ.

The actual height of the guide rib 22 is set at a height H opposite to the upper side of the inner surface of the filter 15 (excluding the dimension IcB on the lower side IcB).

Furthermore, an inclined surface 23 is formed on the upper part of the guide rib 22, and the protruding length becomes shorter as it goes upward.

This dimension is greater than the depth of fit of the lid 18 into the container 8.

Therefore, the guide ribs 22 protrude from the inner circumference of the presser ring 16 toward the outer circumference, but by attaching the lid 18 at an angle to the container 8, the guide ribs 22 are placed inside the filter 15.
2 can be set together with the material input cylinder 17.

In such a configuration, the motor 3 is driven to rotate the basket 10 and materials such as fruits are pushed into the material input tube 17 by the piston 24.

The material is shredded by a scraping cutter 13.

The shredded material is blown away by the centrifugal force, adheres to the inner surface of the filter 15, and continues to rotate.

Therefore, only the liquid contained in the shredded material passes through the filter 15 due to centrifugal force, travels upward along the inner surface of the peripheral wall 14, and is stored in the container 8.

Although the amount of debris adhering to the inner surface of the filter 15 gradually increases,
Since it is smoothed by the guide ribs 22, a uniform thickness is maintained.

During this leveling, debris can be prevented from being ejected to the outside beyond the presser ring 16 by cutting the upper part of the guide rib 22 to have a dimension A and forming an inclined surface 23.

By this stirring, even if the basket 10 or the container 8 is small, the liquid extractability can be maintained in a good state and the squeezing rate can be increased.

When making a large amount of juice, the debris is stirred by the guide ribs 22 and falls below the filter 15, but since the lower part of the guide rib 22 is open with a dimension B, the debris that has fallen downward is not hindered from accumulating.

Even if scum accumulates below the filter 15, the amount of adhesion is limited at the upper part, so the liquid climbs up the inner surface of the filter 15 and escapes to the outside.

In this way, the debris does not adhere unevenly to the inner surface of the upper part of the filter 15 that is far upward from the bottom surface of the basket 10, so that the balance is not disrupted to the extent that a mortar movement occurs.

In this embodiment, by forming the waste storage section 21 having the waste receiving surface 19, the guide ribs 22 are arranged in the filter 1.
It also shows the action of guiding the scum adhering to the slag 5 inward and storing it in the stationary scum storage section 21.

Therefore, the squeezing rate of the liquid can be improved and the rotational balance of the basket can be more effectively maintained, and the space inside the filter 15 can be effectively used to collect the scum. It is also possible to achieve miniaturization.

Since this device is configured as described above, it is possible to use the protrusions to uniformly scrape the scum adhering to the inner surface of the filter to a thickness below a certain level. It is possible to increase the squeezing rate without increasing the size of the basket or container by maintaining a high
In addition, the amount of debris that adheres to the top surface of the filter, which is far from the bottom of the basket, is maintained uniformly and in a small amount by the protrusions.
In particular, the sloped surface of the protrusion allows for smooth uniformity, thereby preventing large mortar movements, and since the protrusion is formed with a certain dimension removed from the bottom of the filter, This has the effect of allowing excess debris to accumulate around the bottom of the filter.
