Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a juicer in which a centrifugal separation basket is rotated by a motor, and material input from a material input tube is crushed by a cutter, and then separated into dregs and juice by a filter.

In conventional juicers, the squeezed juice is almost completely separated from solids and fiber by a filter.

These juices with a low solid content (hereinafter referred to as normal juices) are smooth and easy to drink for infants and sick people.

However, if a certain amount of solids, etc., which are separated by a filter and excreted as dregs, are mixed in, the nutritional value is higher, and the peristaltic movement of the intestines is promoted by the mixed solids, etc., resulting in better digestion.

Therefore, it is desirable to be able to sort juice into normal juice and juice with high solid content and high nutritional value (hereinafter referred to as "dense juice") depending on the physical condition and preference of the person drinking the juice.

Furthermore, conventional juicers have a single horizontal cutter for cutting the material.

Furthermore, by setting the gap between the cutter and the lower end of the material input tube to approximately 1 mm, it is possible to prevent the input tube from coming into contact with the cutter due to variations in component dimensions, and to ensure smooth movement of the material cut with the cutter to the filter. The centrifugal cage was balanced by evenly distributing the material moving over it.

Therefore, the material is only cut in one direction by the cutter, and the grains of the cut material are coarse and a large amount is discharged as slag, which still contains a large amount of unsqueezed juice. It was something.

Furthermore, material that has become thinner than the gap between the cutter and the lower end of the input tube cannot be cut any further and is discharged as slag.

In order to improve the above points, we have installed various mechanisms, changed the shape and arrangement of the blade of the cutter,
Various inventions and ideas have been devised to make the gap between the cutter and the feeding tube smaller, but they all had drawbacks such as complicating the mechanism and not being easy to mold, and none of them were fundamental improvements. It didn't happen.

In view of the above points, the present invention provides a drastic improvement with a simple structure, and one embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 designates a juicer, which includes a base 3 in which a motor 2 is housed, a cutter case 5 detachably attached to the upper surface of the base 3 from which a rotary shaft 4 of the motor 2 protrudes, and a cutter case 5 that is detachably attached to the upper surface of the base 3 from which a rotary shaft 4 of the motor 2 is protruded, and the rotary shaft 4. It consists of a centrifugal separation basket 7 which is removably attached to a rotary table 6 which is attached so as not to be rotatable with respect to each other, and a lid 9 of the cutter case 5 on which a material input cylinder 8 is vertically disposed.

The motor 2 is suspended and supported by the base 3 by screwing a screw 10, which is inserted through the top surface of the base 3, into the upper surface of the protruding side of the rotary shaft 4 with an elastic body 11, 11 interposed therebetween.

The bottom plate 12 is molded from synthetic resin, and an air guide 13 is integrally protruded from the bottom plate 12 and is positioned at a certain distance from the lower end peripheral surface of the motor 2. A radial vent hole 14 is formed in the area surrounded by.

The cutter case 5 has a donut shape, and includes an opening 15 in which the rotary table 6 is located, a juice receiving portion 16 formed around the opening 15, and a juice receiving portion 16 formed around the receiving portion 16. It consists of a slag reservoir section 17.

The bottom surface of the juice receiving section 16 is formed in a spiral shape that becomes lower in the direction of rotation of the centrifugal separation basket 7, and a juice outlet 18 communicating with the outside of the cutter case is formed from the lowest part thereof.

The centrifugal separation cage 7 includes a synthetic resin cage holder 19 that is fitted onto the rotary table 6 and rotates integrally with the rotary table 6, a filter 20 in the shape of an inverted truncated cone fixed to the table 19, and the filter 20. It consists of a cutter plate 21 fixed to the bottom of the.

The upper edge of the filter 20 is reinforced with an upper reinforcing frame 22, and the lower edge is reinforced with a lower reinforcing frame 2, which also serves as an attachment part to the pedestal 19.
3 has been reinforced.

Further, an annular stepped portion 24 is formed in the middle portion of the lower reinforcing frame 23, with which the outer peripheral edge of the cutter plate 21 comes into contact.

The filter 20 is provided with a large number of through holes, and the upper half of the filter 20 is provided with a slit-like hole 25 that extends longitudinally in the circumferential direction of the centrifugal separation cage.

A slit-like hole 26 larger than the hole 25 is formed in the lower half of the filter 20, and the longitudinal direction of the hole is inclined in the circumferential direction of the basket and in the opposite direction to the rotation direction.

Furthermore, relatively large round holes 27 are formed at several locations in the lower half.

The filter 20 and the cutter plate 21 are fixed to the basket stand 19 by the filter 20 and the cutter plate 21.
This is done by supporting the lower reinforcing frame 23 and fixing each part at the same time with rivets 28.

In the fixed state, the outer peripheral edge of the cutter plate 21 is pressed against the stepped portion 24 of the lower reinforcing frame 23 in a watertight manner.

Further, the stepped portion 24 also serves as a position for the cutter plate 21.

The cutter plate 21 has a dish shape with an annular step 29 formed on the outer periphery, and the cutter plate 21 is made by press-molding a stainless steel disc, and then the cutter plate 21 is formed by press-molding a stainless steel disc, and then the cutter plate 21 is formed by press-molding a stainless steel disc, and then forming a flat central part 30 of the stainless steel disk and forming the step. A large number of cutting blades 31, 32, . . . are formed on the upper surface of the portion 29.

The cutting blades 31 formed in the central portion 30 are arranged in a conventionally known manner, such as in a radial or spiral pattern.

Further, the cutting blades 32 formed on the upper surface of the stepped portion 29 are not limited to conventional cutting and raising blades, but may be fine-grained blades like sandpaper or files.

Further, the side surfaces 33 of the step portion 29 connecting the central portion 30 and the upper surface of the square step portion 29 are formed at an angle of about 45 degrees, and the material cut in the central portion 30 is completely cut on the side surfaces 33. The material is slowly fed to the upper surface of the stepped portion 29 without slowing down its movement speed.

The lid body 9 is removably attached with a clamp so as to close the upper opening of the cutter case 5.

The material input cylinder 8 vertically disposed on the lid 9 has a cross section D that covers substantially the entire surface of the central portion 30 of the cutter plate 21.
It is shaped like a cylinder.

Further, at the lower part of the charging tube 8, there is a stepped portion 2 of the cutter plate 21.
A flange portion 34 extending to the filter 20 is provided so as to cover the upper surface of the filter 9 .

The gap between the lower end of the charging cylinder 8 and the center portion 30 of the cutter plate 21, and the gap between the collar portion 34 and the upper surface of the stepped portion 29 of the cutter plate 21 are set to about 1 mm as in the conventional case.

In addition, the side surface 33 of the stepped portion 29, the charging tube 8, and the flange portion 3
4, a space having a substantially triangular cross section is formed.

A reverse gutter-like exposed material portion 35 is formed on the lower side of the flange portion 34 for pushing out a portion of the input material A to the side and bringing it into sliding contact with the inner circumferential surface of the filter 20 of the centrifugal separation basket 7.

The entrance of the exposed portion 35 is located on the upper side of the centrifugal separation basket 7 in the direction of rotation, and the exposed portion 35 extends in the direction of the inner surface of the material input cylinder 8.

Reference numeral 36 denotes a juice concentration switching plate that is inserted through an insertion portion 37 formed in the lid body 9 and inserted into an insertion portion 38 formed in the material exposed portion 35 to appropriately shut off the material exposed portion 35.

The insertion part 38 formed in the exposed part 35 is formed near the exit of the exposed part 35 located above the step part 29.

The switching plate 36 engages and holds the exposed portion 35 in two states: a closed state and an open state.

Next, the action will be explained.

First, a state in which the exposed portion 35 is closed by the switching plate 36 will be described.

The material is cut into appropriate sizes and placed into the material input cylinder 8.

Since the input tube 8 is approximately cylindrical, apples, which were conventionally cut into 1/12 pieces, can be added by cutting them into 1/4 pieces. You can squeeze the juice smoothly without any effort.

Also, since the input tube 8 is large, if the input material becomes small to some extent, the cutting blade 31 of the central part 30 of the cutter plate 21...
- This makes it difficult to cut, and it bounces inside the input tube 8 and rotates together with the cutter plate 21.

However, the materials that are about to rotate together are caught on the entrance edge of the exposed portion 35 formed in the input cylinder 8, and their movement is stopped and the materials are reliably cut by the cutting blade 31.

Further, the material that has become so small that it is pushed into the exposed portion 35 moves along the stepped side surface 33 of the cutter plate 21 into the stepped portion 29.
Since the exposed portion 35 is closed, the cutting blade 32 on the upper surface of the stepped portion 29 can reliably cut the stepped portion 29 .

Since the side surface 33 is formed as an inclined surface, the material A is smoothly guided to the upper surface of the step portion 29.

Further, the exposed portion 35 has its inlet located on the upper side in the rotational direction of the centrifugal separation basket 7 and extends in the tangential direction of the material input cylinder 8, so that the material A, which has become smaller, is immediately caught in the inlet of the exposed portion 35. Alternatively, the material A is pushed into the exposed portion 35, and the force for further pushing the pushed material A is strong.

The cut material jumps out from the gap between the input tube 8 and the cutter plate 21 and hits the side surface 33 of the stepped portion 29.

The speed of the material that hits the side surface 33 is reduced, and since the gap between the side surface 33, the input tube 8, and the flange 34 is large, the material itself is oriented in a different direction from when it was thrown out. At the same time, the direction of movement of the material changes.

The material then moves over the side surface 33 to form the stepped portion 2.
9. Guided to the top surface.

At this time, the material is pushed into the narrow gap between the upper surface of the stepped portion 29 and the flange portion 34, so that it is cut again by the cutting blade 32.

At this time, the orientation and movement direction of the material itself are changed by the side surface 33, and by being pushed into the gap, the material is cut in a different direction and becomes finer grained.

Therefore, it was not possible to cut the central part 30 of the cutter board 21.
Materials as thin as mm or less can also be cut when passing over the upper surface of the stepped portion 29 of the cutter plate 21.

The material cut by the cutter plate 21 is separated into juice and slag, which are sent to a filter 20.

After the squeezed juice is received by the juice receiving part 16, it flows along the bottom surface toward the outlet 18, and is collected in a juice receiving container 39 located below the outlet 18.

The slag moves on the filter 20 and is discharged into the slag reservoir 17.

The material squeezed by the filter 20 is very fine and the fibers are finely cut into uniform particles, so the juice contained in the material can be squeezed out sufficiently and the juice can be squeezed out into the holes 25, 26, 27 of the filter 20. There is less material getting caught, the filter 20 is less likely to be clogged, and the juice production rate is improved.

Note that the juice production rate is the ratio of the weight of squeezed juice to the weight of input materials expressed as a percentage.

The squeezed juice contains very little fiber and is a normal, smooth juice.

Next, a state in which the exposed portion 35 is opened will be described.

The material A, which has become smaller and has been pushed into the exposed portion 35, has its tip protruded from the exposed portion without being cut due to the centrifugal force of the cutter plate 21 and the pressure of the material pushed in later, and is brought into sliding contact with the lower part of the filter 20. .

Therefore, the cut material that hits the lower part of the filter 20 forcefully due to centrifugal force and sticks into the hole of the filter 20, blocks the hole and accumulates there, is scraped off by the uncut material A that slides in contact with the lower part of the filter 20, and is Since the portion is pushed out of the filter 20 through the holes, not only a large amount of solids and fibers are mixed into the juice, but also the lower part of the filter 20 is kept free of clogging.

Therefore, the juice squeezed when the material exposure portion 35 is open is a thick, thick juice with high alkalinity and nutritional content.

In this manner, switching between the thick juice and the normal juice can be performed by a simple operation such as appropriately blocking the material exposure portion 35, which pushes out a portion of the input material laterally, with the switching plate 36.

Further, when the state is continuously changed from the state of squeezing strong juice to the state of squeezing normal juice, the material A located in the exposed portion 35 is pressed against the upper surface of the step portion 29 by the switching plate 36, so that the step portion The material A can be cut with the cutting blade 32 on the top surface of the 29, and the uncut material does not come out of the exposed part 35 without having to take the trouble to cut the material A.
The changeover can be completed smoothly without the need to stop the operation and remove the material A from the exposed portion 35.

As described above, the present invention includes forming an annular step on the outer periphery of the inner bottom surface of a rotationally driven centrifugal separation cage, disposing a material cutting cutter on the inner bottom surface, and disposing a material feeding tube in the center of the inner bottom surface. The lower ends are positioned close to each other, and a flange is provided on the outer side of the lower part of the input cylinder to cover the stepped part, and a part of the input material is pushed out to the side under the flange to form the centrifugal separation basket. A reverse gutter-like exposed material part that slides on the inner peripheral surface of the filter is formed, and the vicinity of the outlet of the exposed part is appropriately blocked by a juice concentration switching plate, so the juice can be switched smoothly with a simple structure. This can be done reliably and has the effect of preventing clogging of the lower part of the filter.

Moreover, since the material can be cut into fine particles with uniform grains, the juice production rate is also improved.
