Description

[Detailed Description of the Invention] The present invention relates to a so-called lees retention type juicer that stores lees in a centrifugal separation basket, and aims to improve the juice extraction efficiency by making the cut pieces of the cut material finer. .

Figures 1 and 2 show the lees retention type juicer seen in the Congregation of Song Dynasty.

1 is a centrifugal/separation layer, and a cutting blade 2 is provided at the center bottom. Reference numeral 3 denotes a charging tube disposed coaxially with the centrifugal separation basket 1, and approximately half of the loading tube 3 is an open portion 1], which constitutes a loading section 4 for fruits and the like.

5 indicates the wall surface at the tip of the charging cylinder 3, and this tip -■ wall
A protrusion 6 is formed on the □ surface 6 adjacent to the input port 4 with a slight gap t from the cutting blade 2.

Next, problems with the conventional example will be described. When the object to be cut (fruits and vegetables) is pushed and the bale 7 is buried in the cutting blade 2, the object to be cut is finely pulverized between the cutting blade 2 and the small gap t between the protrusion 6 (the second In the figure, the arrow indicates the direction of rotation of the cutting blade).

If the object to be cut is a hard material such as carrot, the cutting resistance will increase, and the pressure to press the cutting blade 2 with the push rod 7 will inevitably increase. Then, a thrust load is applied to the centrifugal separation cage 1, and the input port 4 is connected to the centrifugal separation cage 1.
Since the centrifugal separation cage 1 is shifted from the center of the center, the centrifugal separation cage 1 is slightly tilted with the center as a fulcrum.

Unfortunately, the gap t between the protrusion 6 and the cutting blade 2 becomes larger than the original design value, and therefore the thickness of the cutting piece passing through this gap also becomes larger than t.

Generally, the squeezing rate of a juicer is related to the degree of pulverization of the material, that is, the fineness of the pulp, and the generation of coarse pieces will eventually lead to a decrease in the juice squeezing rate.

The present invention eliminates the drawbacks seen in the above conventional example,
Hereinafter, a detailed explanation will be given based on the drawings of the embodiment.

In FIG. 3, 8 is the main body of the juicer which has legs 10 on the bottom plate 9, 11 is a motor installed inside the main body 8 via a buffer 12, and 13 is placed on the main body 8, and there is a juice receiver inside. 14. A juice receiver having a juice outlet 16 at the bottom is a container, and inside the container 13 there is a rotatable substantially cylindrical centrifugal separation shell (hereinafter referred to as a spinner) whose diameter increases upward. ) 16 are deployed.

At the center bottom of the spinner 16, a cutting blade (hereinafter referred to as a liquid balancer 18 filled with an equivalent amount of liquid) is provided. Reference numeral 19 is a cylindrical comb-shaped filter detachably inserted into the spinner 16. Reference numeral 20 indicates a juice filter. The receptacle is a charging cylinder attached to the container lid 21, and this charging cylinder 20 is arranged coaxially with the spinner 16, and about half of it forms an opening, and is inserted into the cutter 17 by a push rod 22. An input port 23 is formed which has the role of guiding the fruits being pushed away. 24 indicates the tip wall surface of the input tube 20, and this tip has a cutter 17 and a plurality of holes with a slight gap t. A projection 26 is provided.

The shape and function of the plurality of projections 25 will be described based on FIG. 4. In FIG. 4, the arrow indicates the cutter 17
and the rotation direction of the spinner 16. Protrusion 26
Among them, the first protrusion 26A is adjacent to the edge of the input port 23,
Furthermore, they are provided at the same position in the rotational direction of the cutter 17. This protrusion 26mm is
The purpose is to prevent fruit etc. from being bitten into the tip of the input tube 2o by the rotational force of the cutter 17, and to make the cut pieces of the cut object into fine pieces with a thickness of t or less.

That is, the function and effect of this protrusion 26m are the same as those seen in the past. On the other hand, the second protrusion 25B
It is radially provided at a position displaced by about 180 degrees from the center.

At this time, when cutting a hard material such as carrot, for example, as explained in the conventional example, the spinner 16 tilts somewhat with the center as the fulcrum due to the increased pressure of the pusher rod 22. If the pressing force is further increased, the buffer body 12 supporting the motor 11 and the spinner 16 will also be compressed to some extent, and the entire spinner 16 will be pushed downward. At this time, the gap t between the protrusion 25 and the cutter 17 becomes considerably larger than the original design value due to the increase in the gap due to the inclination of the spinner minus the downward movement of the entire spinner.

However, regarding the protrusion 25B, the cutter 17 (
7) The interval t between lIjft is [reduction in gap due to spinner tilt] + [downward movement of the entire spinner],
It does not vary significantly from the original design value.

That is, the thick coarse pieces generated at the protrusion 25B due to the increased suppression are again finely pulverized at the protrusion 25B.

Note that if the width dimensions of each of the protrusions 25 and 26B are made too large (for example, by making the protrusions 25 and 25 into one piece), it will take time for the generated coarse pieces to escape from the protrusions. It has been experimentally confirmed that this causes a braking force to be applied to the rotation of the spinner 16, and that abnormal vibrations are likely to occur due to the biting of the dog section. 2 in the diagram
6 is a speed reducer of an appropriate type, and the motor 110 rotations are transmitted to the spinner 16 through this speed reducer 26 and coupling 27.
transmitted to. 28 indicates a cooling fan for the motor 11.

As described above, the present invention provides a plurality of protrusions on the tip wall of the input tube with a small gap from the cutting blade, so that the workpiece can be finely pulverized regardless of the spinner's inclination or downward movement. This improves the juice squeezing efficiency, and the structure is simple as it is just an addition of protrusions.
