Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention comprises a centrifugal separation cylinder which has a cutter for cutting material on the inner bottom and is rotated by a motor, and a centrifugal separation cylinder which is attached to the inner periphery of the separation cylinder and which cuts the material. The present invention relates to a juicer that is equipped with a cylindrical filter that separates the collected material into waste and liquid, and that collects the waste in a centrifugal separation cylinder.

(b) Prior Art This type of juicer is known, for example, from Japanese Utility Model Publication No. 10504/1983. The filter used in this juicer is formed into a comb-like shape to form a large number of vertical liquid outflow slits, and debris adheres to and accumulates on the inner peripheral surface. In order to remove this adhered debris, the filter is elastically deformed, and the change in the spacing between the slits due to this deformation is relatively large at the lower end, but becomes smaller as it goes upward. Therefore, it is difficult to remove the scum, and the scum cannot be removed by simply washing with water, and the scum must be scraped off using a brush or the like, making it difficult to remove the scum. This difficulty in removing debris has been the main reason for hesitation in using Jusa itself.

(c) Purpose of the Invention In view of the above-mentioned drawbacks, it is an object of the present invention to provide an easy-to-use juicer by making it easy to remove debris.

(d) Structure of the Invention The structure of the present invention consists of a centrifugal separation tube that has a cutter on the inner bottom for cutting the material and is rotationally driven by a motor, and a centrifugal separation tube that is detachably attached to the inner circumference of the separation tube and holds the cut material. A juicer that is equipped with a cylindrical filter that separates waste and liquid, and that collects the waste in the centrifugal separation cylinder, wherein the cylindrical filter has a helical body having a spiral liquid flow gap that allows the interval to be expanded. It is characterized by being composed of.

Due to this structure, waste adheres to and accumulates on the inner circumference of the filter, but by expanding and contracting the filter in the direction of the cylinder axis or deforming it in a direction perpendicular to the cylinder axis, the interval of the liquid flow gap changes greatly, so that the waste adheres to and accumulates on the inner circumference of the filter. If the filter is washed with the filter easily separated from the filter and the gap is widened, the debris stuck in the gap can be easily washed away.

56 is a cylindrical portion 29b to which the filter 30 is attached.
The inner peripheral surface of the tube has a tapered shape with a larger diameter at the top so that the separated liquid can easily rise.
A plurality of vertical protrusions 57 are formed at appropriate intervals, and a liquid flow gap 58 is provided between the protrusions 57 and the outer peripheral surface of the filter 30. The cross-sectional shape of the protrusions 57 is such that the width thereof decreases from the bottom to the top and has a substantially triangular shape, so that the liquid and fine fibers can easily rise.

59 is a filter locking protrusion formed at the lower end corner of the inner circumferential surface 56 to prevent rotation of the filter 30, and is formed on an extension of the protrusion, but is not limited to this. .

Note that the liquid flow gap 58 may be provided by forming a protrusion (not shown) on the outer circumference of the filter 30 instead of forming a protrusion on the inner circumferential surface 56.

Reference numeral 60 denotes a large diameter portion formed at the upper end of the inner circumferential surface 56, on which locking protrusions 62 of a lid 61 to be described later are integrally protruded inward.

Reference numeral 63 denotes a fluid balancer formed in a substantially L-shape over the side and bottom surfaces of the cylindrical portion 29b.

A suitable number of vertical resistance plates 67 are integrally provided projecting from the 5 side, and a suitable amount of balancer liquid 68 is sealed in this space. The bottom cover 66 has a concave-convex fit between the lower end of the outer wall 65 and an inner end of the lower surface of the bottom step portion 52, and is welded and sealed, and this concave-convex fit improves sealing performance. The outer wall 65 has a tapered shape with a larger diameter at the bottom so that the lower part of the sealed space is wider than the upper part, so that the liquid 6
8 is concentrated downward to prevent the liquid from rising upward.

As shown in FIGS. 13 to 17, the spiral filter 30 is composed of a multi-stage cylindrical spiral body 30A made of synthetic resin, for example, ABS resin.
A spiral liquid flow gap 69 is formed between each stage and has a spring property. This spiral 30A
is formed by a mold so that the gap 69 is expanded as shown in FIG. 15 when no force is applied in the contraction direction of the cylinder axis (natural extension state), and when the lid 61 is closed, the gap 69 is expanded. When the gap 69 is compressed and reaches its minimum size, when a force is applied in the direction of extension of the cylinder axis from the state shown in the same figure, the gap 69 becomes further expanded, and when a force is applied in the horizontal direction, the gap 69 becomes smaller. This has the property of causing a lateral shift, which also causes the interval of the gap 69 to expand in the left-right direction. The length of the spiral body 30A in the cylindrical axis direction is longer than the depth l1 of the cylindrical portion 29b even when the lid 61 is in the closed state and in the naturally extended state, making it easy to take out the filter 30.

Further, the uppermost stage 30a of the spiral filter 30,
The lowermost stage 30b is configured so that the end surfaces 70, 70 are flat surfaces with no steps, thereby preventing a large gap from being formed between the inner surface of the lid 61 and the inner bottom surface of the cylindrical portion 29b, thereby preventing the outflow of waste. There is. To change the height dimension of the above cross section,
This can be done by gluing ring-shaped bodies for height adjustment on the top and bottom surfaces of a spiral body with the same cross-sectional shape, or by changing the cross-sectional shape with a mold, but in this example, the latter is adopted. . and end portions 71, 71
The cylinder has a sufficient thickness in the axial direction to ensure strength at the ends, and protruding pieces 72 are provided at the ends 71, 71, and the protruding pieces 72 are fitted onto the mating surfaces corresponding to the ends 71, 71. A groove 73 is formed so that even if a small amount of force is applied to the ends 71, 71 when pulling up the filter 30, the ends 7, which have a small cross section,
1,71 is configured so as not to be damaged,
A radius is formed at the corner portion so that the protruding piece 72 and the groove 73 are disengaged when a force exceeding a predetermined value is applied. Since this locking is performed on the outer peripheral side of the filter 30, there is less adhesion of debris and cleaning is easy.

Further, the spiral body 30A has an outer diameter slightly smaller than the inner diameter of the cylindrical portion 29b (the tips of the protrusions 57),
The outer circumferential surface 74 is in contact with the protrusions 57, and the inner circumferential surface 75 is in contact with the protrusions 57, and as shown in FIG.
By forming the tapered surfaces 75a, 75a so that the diameter increases symmetrically toward the bottom, the separating tube 2
By rotating the filter 9, the scum is first accumulated from below, and the scum is easily removed from the filter in the downward direction. In addition, in the embodiment, the filter 30
In order to eliminate vertical directionality, the diameter is larger toward the top and bottom, but if it has directionality, it may be formed into a tapered surface that becomes larger in diameter from the top toward the bottom.

Further, the cross-sectional shape of each step of the spiral body 30A is as shown in FIG.
6a and 76a, thereby reducing the gap 6
9, the flow resistance of the liquid flowing out is reduced, and the inner surface 76b is made a flat surface to facilitate the movement of waste. Note that the form of this notch may be as shown in Figure 28 I to I, or if it is not necessary to improve the mobility of debris, the inner surface may be curved as shown in Figure 28 H to I. .

Furthermore, since the spiral body 30A requires a spring force to prevent it from stretching too much when the filter is taken out, it requires a somewhat wide cross-sectional area, but in this embodiment, the vertical width F is longer than the horizontal width E of the cross-section. . By setting F>E, the filter 30
When the internal space volume is constant, the filter 30
This prevents the outer diameter from increasing. However, if the outer diameter is not restricted, F≦E may be set as shown in FIG. and,
The contact surfaces of each stage are flat surfaces 77a, 7 so that the cylindrical shape is not destroyed even if the filter 30 is displaced laterally.
7b... or a concave surface 78a and a convex surface 78 whose contact surfaces fit into each other in a concave and convex manner as shown in FIG.
It is formed in b.

Further, referring to FIG. 6, the spiral body 30A forms a liquid flow gap 69 between each stage, and also forms liquid flow gaps 79 and 80 between the bottom surface of the lid 61 and the top surface of the low step part 52 of the cylindrical part 29b. ing. In the lid closed state of the figure, in the spiral gap 69, the lower surface of the spiral body 30A has approximately the entire width in the radial direction of the flat surface 77b so that the gap between each stage does not become narrower than a certain value (for example, 0.4 mm). Space-maintaining protrusions 81 are formed at equal intervals in the longitudinal direction of the gap 69, and in the gaps 79 and 80, spacing-maintaining protrusions similar to the protrusions 81 are formed on the upper and lower end surfaces of the spiral body 30A. 82... is formed.
These protrusions 81..., 82... make the ease of liquid outflow approximately equal over the entire vertical direction of the filter. Incidentally, the latter protrusion 82... is the spiral body 30.
Instead of providing it on A, it may be provided on the lid 61 and cylindrical part 29b side, and the former protrusion 81... is provided on the spiral body 30A
It may be provided on the upper surface side. Also, the protrusions 81..., 8
2... may be a knurled projection.

Further, the spiral body 30A is prevented from rotating by engaging the cylindrical portion 29b and the lid 61 with the concave and convex portions. That is, substantially V-shaped engagement grooves 83 having the same shape are formed at the upper and lower outer corners of the uppermost and lower stages of the spiral body 30A at a predetermined angle (in this embodiment, approximately
60 degrees) are formed in a pair at the target position, and a lid 6 is placed in the upper groove 83...
Approximately V-shaped protrusions 84 are formed at predetermined angle intervals (approximately 60 degrees in this embodiment) on the inner circumferential corner of 1.
By fitting, rotation is prevented between the lid 61, and by fitting the protrusions 59 of the cylindrical portion 29b into the grooves 83 at the lower end, rotation is prevented between the separation tube 29. being done.

Further, the winding direction of the spiral body 30A is set so that the diameter increases. For example, when the rotation direction of the separation cylinder 29 is counterclockwise x when viewed from above, the winding direction from the top to the bottom is set to the direction in which the diameter increases. It is shaped so that it faces clockwise when viewed. If the winding direction is reversed, as the separation tube 29 rotates, the diameter of the helical body 30A will contract, and at the same time, a force will act in a direction in which the length in the axial direction of the tube will increase, and this force will try to remove the lid 61. This may cause damage to the engaging portion between the lid 61 and the separation cylinder 29 and cause the lid 61 to fly off. Since force is applied to the helical body 30A in a direction in which its diameter is expanded and its length in the axial direction of the cylinder is contracted, such a drawback is not present, and the locking structure of the lid 61 can be simplified.

As shown in FIGS. 6 and 20 to 22, the lid 61 is fitted and locked into the large-diameter upper end portion 60 of the cylindrical portion 29b to prevent the filter 30 from coming off and to be stored on the inner periphery of the filter 30. It is configured to have a function of preventing debris from flying out. 61a is a cylindrical vertical part in contact with the large diameter part 60, and protrusions 85... are provided at equal intervals on the outer peripheral surface, and these protrusions 85, 85

Next, the operation of the above embodiment will be explained. Before liquid generation, the projections 72, 72 at the starting end of the filter 30 in the extended state as shown in FIG. 16 are inserted into the grooves 73, 7.
3, and then installed into the cylindrical portion 29b.
Then, while compressing the filter 30, the lid 61 is
are fitted into the large-diameter portion 60 of the cylindrical portion 29b, and the protrusions 62 are inserted into the horizontal grooves 86b from the vertical grooves 86a, and the lid 61 is rotated clockwise when viewed from above to insert the protrusions 62 into the horizontal grooves 86b. By positioning it in the inner part, it is coupled to the cylindrical part 29b. In this state, the filter 30 is contracted as shown in FIG. 6 to prevent it from popping out. A gap 78 is formed between the inner surface of the lid 61 and the upper end surface 70 of the filter 30 by the projections 82 on the upper end, and a gap 69 is formed by the projections 81 .
However, the gap 80 is maintained at a constant interval by the projections 82 at the lower end. At the same time, the lower end of the filter 30 is locked to the cylindrical portion 29b by the engagement between the protrusions 59 and the grooves 83 at the lower end, and the protrusions 84 and the grooves 8 at the upper end are engaged with each other.

It flows out of the separation cylinder 29 through 91. When the material is further cut and accumulated inside the diameter of the opening 93 of the lid 61, the scraps are discharged to the outside of the separation tube 29 by the protrusions 96.

In order to remove the waste after producing such waste, first stop the electric motor, remove the clamp device, and remove the container lid 21b. When the lid 61 is rotated to disengage from the cylindrical portion 29b, the filter 30 expands due to its own elasticity as shown in FIG. 26, and its upper end protrudes higher than the upper end of the cylindrical portion 29b. The filter 30 can be easily taken out of the separation tube 29 by holding this protrusion and pulling it upward. This filter 30 has debris K attached to the lower part of the inner periphery.By holding both ends of the filter 30 and expanding and contracting it, as well as shifting it laterally as shown in FIG. easily separate from the Furthermore, fibers and the like remaining in the gap 69 can be easily washed away by washing with water in this expanded state because the gap 69 expands due to its own elasticity.

In addition, in order to clean the inside of the separation cylinder 29, it is sufficient to disengage the base part 29a and the connector 11, remove the separation cylinder 29, and then wash the inside with water. Remove, base 29
By separating the cylindrical portion a and the cylindrical portion 29b, cleaning thereof becomes easier. .

Next, in order to perform a grating function such as grating radish or shaving ice, the cylindrical part 29b is separated from the base part 29a, only the base part 29a is connected to the connector 11, and the valve 25 is closed to drive the electric motor.
Then, when the material is inputted from the input tube 44 at the same time as when generating the youth, the material is transferred to the grating blade 39.
The grated material is stored in the receiver 21a.

It should be noted that the present invention is not limited to the above embodiment, and for example, the winding direction of the filter 30 and the separating tube 29
The relationship between the direction of rotation and the direction of rotation may be reversed.
As shown in FIG. 9, members 121 and 122 functioning as a lid 61 may be integrally formed at the upper end of the filter 301. One member 121 prevents debris from flying out, and the other member 127 elastically engages with the cylindrical portion 29b. Further, the filter 30 may be configured to be in the most contracted state when no force is applied. Furthermore,
The spiral body 30A of the filter 30 may be formed hollow, and the cross-sectional shape may be a shape other than that shown in FIG. 28.
In this case, the spiral body 30A can be formed by extrusion molding. Further, although it is preferable that the projections 81, .

(F) Effects of the Invention According to the present invention configured as described above, by expanding and contracting the spiral body in the direction of the cylinder axis or shifting it in a direction perpendicular to the cylinder axis direction, the interval of the liquid flow gap can be greatly changed. This makes it easy to separate the waste from the filter, and also allows cleaning with a large liquid flow gap, making it easy to clean the filter and keeping the filter clean at all times. It has great effects such as being able to maintain the temperature.
