Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Field of Application The present invention comprises a centrifugal separation tube that has a cutter on the inner bottom for cutting material and is rotatably driven by a motor, and a centrifugal separation tube that is attached to the inner periphery of the separation tube to cut the material. It is equipped with a cylindrical filter that separates the collected material into waste and liquid, and the waste is removed from the centrifugal bone 1lII111i.
This relates to a juicer that accumulates in an IF.

(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 in a comb-like shape to provide a large number of vertical liquid outflow slits. As a result, debris adheres and accumulates on the inner circumferential surface.In order to remove this adhered debris, the filter is elastically deformed, but the change in the spacing between the slits due to this R shape is relatively large at the lower end, but at the upper end. As the age progresses, the sludge becomes thinner.Therefore, it is difficult to remove the scum, and the scum cannot be removed simply by washing with water, and the scum must be scraped off using a brush or the like, making the scum removal work difficult.

This difficulty in removing the scum has been the main reason why juicers themselves are discouraged from using the juicer itself.

(c) Purpose of the Invention In view of the above-mentioned drawbacks, the present invention aims to provide an easy-to-use juicer and increase the amount of juice squeezed by making it easier to remove the scum.

(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 that cuts the material and is rotated by a motor, and a centrifugal separation tube that is detachably attached to the inner periphery of the separation tube to hold the cut material. A juicer comprising a cylindrical filter for separating waste and liquid, and storing the waste in the centrifugal separation cylinder, wherein the cylindrical filter has a helical shape having a spiral liquid flow gap whose interval can be expanded. and a filter and a holding means are provided above the cylindrical filter of the centrifugal separation cylinder, and the inner peripheral surface of a hanging ring provided on the outside of the upper end of the filter is expanded downward in the filter holding means. In addition, a liquid flow gap is formed between the upper end of the centrifugal separation cylinder and the lower end of the hanging ring body.

Due to this configuration, 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 the cylinder axis in the right angle direction, 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 caught in the gap can be easily washed away. Further, the liquid that has passed through the liquid flow gap at the upper end of the filter is guided by the inner peripheral surface of the hanging ring and smoothly flows out of the separation cylinder through the liquid flow gap.

59)... is a filter locking protrusion formed on a part of the lower end corner of the inner circumferential surface (56), which prevents the filter (3o) from turning 0 times, and is formed on an extension of the protrusion. However, it is not limited to this.

Note that the liquid flow gap (58) may be provided by forming protrusions (not shown) on the outer circumference of the filter (3o) instead of forming protrusions on the inner circumferential surface (56).

(60) is a large-diameter portion that can be formed at the upper end of the inner peripheral surface (56), and a locking protrusion <62) of the lid (61), which will be described later, is integrally protruded inward.

(63) is a fluid balancer formed in an abbreviated shape on the side and bottom surfaces of the cylindrical portion (29b), and the side surface of the cylindrical portion (29b) does not become a double wall (64) (65) with an opening on the bottom. At the same time, this lower opening is closed with a ring-shaped bottom cover (66) to form a sealed space, and a suitable number of vertical resistance plates (67) are installed in this space from the outer wall (65) side. In addition to protruding, an appropriate amount of balancer liquid (68) is sealed in this space. The bottom cover (66) is connected to the lower end of the outer wall (65) and the bottom step (5).
The inner end of the lower surface of 2> is fitted in a concave and convex manner, and is welded and rolled, and this concave and convex fit improves the knot property.

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, and the liquid (68
) is allowed to concentrate downward and prevents the liquid from rising upward.

As shown in FIGS. 6 to 9, the spiral filter (30) is composed of a multi-stage cylindrical spiral body (30A) made of synthetic resin, for example, ABS resin, with a spiral liquid flow gap between each stage. 69) is formed and has spring properties.

This spiral body (30A) is formed by a mold so that the gap (69) is in an expanded state as shown in Fig. 6 when no force is applied in the direction of contraction in the direction of the cylinder axis (natural extension state). When the lid (61) is closed, it is compressed and the gap (
69) is in the most contracted state, and when a force is further applied in the direction of extension in the cylinder axis direction from the state shown in the same figure, the gap (69) is further reduced.
When the distance between the gaps (69) increases and a force is applied in the horizontal direction, horizontal threading occurs between the steps, which also causes the distance between the gaps (69) to expand in the left-right direction. This spiral (30A)
The length in the axial direction of the cover is longer than the depth 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).

In addition, the uppermost stage (30a) and the lowermost stage (30b) of the spiral filter (30>) are arranged so that the end surfaces (70) (70) are flat surfaces with no steps (excluding the protrusions (82) described later). (61) A large gap is not formed between the inner surface and the inner bottom surface of the cylindrical portion (29b), thereby preventing the outflow of waste.How to change the height dimension of the above-mentioned 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 was adopted. The thickness of the end portion <71) (71) in the axial direction of the cylinder is sufficiently ensured to ensure the strength of the end portion, and the end portion (71) (
71) is provided with a protruding piece (72), and the ends (71) (71)
A groove (73) into which the protruding piece (72) is fitted is formed on the mating surface corresponding to the groove (73), so that even if a slight force is applied to the end (71) (71) when pulling up the filter (<30), The end portions (71) (71) having a small cross section are configured so as not to be damaged, and when a force of E is applied beyond a predetermined level, the projecting piece (72)
) is rounded at the corner so that the groove (73) can be disengaged from the groove (73). Since this locking is performed on the outer peripheral side of the filter (4), there is less adhesion of debris and cleaning is easy.

In addition, the spiral body (30A) is formed so that its outer diameter is 9 mm smaller than the inner diameter (tip of the protrusion (57)) of the cylindrical portion (29b), and the outer circumferential surface 74) is smaller than the protrusion (57)... The inner circumferential surface (75〉) is in contact with
The tapered surface (75
a) (75a), the rotation of the separation cylinder (29) allows the scum to be accumulated from below first, and also makes it easy to remove the scum from the filter in the downward direction. In the embodiment, the filter (30) is formed to have a larger diameter toward the top and bottom in order to eliminate the vertical directionality, but if it has directionality, the diameter will increase from the top to the bottom. It may be formed into a tapered surface.

Moreover, the cross-sectional shape of each step of the spiral body (30A) is as shown in FIG.
a), thereby reducing the flow resistance of the liquid flowing out from the gap 69), and making the inner surface (76b) a substantially vertical flat surface to facilitate the movement of waste. Note that the form of the notch is not limited to that shown in the drawings.

Furthermore, if it is not necessary to improve the mobility of debris, the inner surface may be curved.

Further, referring to FIG. 4, the spiral body (30A) forms a liquid flow gap (69) between each stage, and also forms flat surfaces (77a) (77b) on the surfaces forming the gap, and the lower surface of the lid (61). , f
A liquid flow gap (79) (80) is formed between the fN portion (29b) and the upper surface of the low step portion (52). This gap is determined when the lid is closed as shown in the figure, and the gap between each stage is a constant value (for example, 0.4
am+) 2" spiral gap (69) so as not to become narrow
In this case, there is a flat surface (77b) on the lower surface of the spiral body (30A).
Spacing protrusions (81), all of the same height, are formed at equal intervals in the longitudinal direction of the gap (69) over substantially the entire width in the radial direction, and in the gaps (79) and (80), Projections (81) on the upper and lower end surfaces of the spiral body (30A)...
Similar spacing-maintaining protrusions (82) of the same height are formed. These protrusions (81>..., (82))
- The ease with which liquid flows out is approximately the same over the entire vertical direction of the filter.

In addition, the latter protrusions (82)... may be provided on the M (61) and cylindrical part (29b) side instead of being provided on the spiral body (30A), and the former protrusions (81>...) may be provided on the spiral body (30A). 30A).Also, the projections (81)..., (8
2)... may be a knurled protrusion.

The spiral body (30A) also has a neck <29b) and a lid (
61), rotation is prevented by concave and convex engagement. That is, at the uppermost and lower stages of the spiral body (30A), approximately V-shaped engagement grooves (83) having the same shape are provided at the outer corners of the spiral body (30A).
. . . are formed in large numbers over a predetermined angle range (approximately 60 degrees in this example) at the target position, and the upper grooves (83) . The lid ( 6
1) is prevented from rotating, and the groove (83〉・
By fitting the protrusion (59) of the cylinder portion (29b) into the separation cylinder (29), rotation is no longer prevented.

In addition, the spiral body (30A>) is set so that the winding direction is the direction in which the diameter widens, that is, for example, when the rotation direction of the separation tube (29) is counterclockwise (x) when viewed from above, It is formed so that the winding direction is clockwise when viewed from above.If it is wound in the opposite direction to this winding direction, the separation tube 29)
As the diameter of the helical body <30A) decreases with the rotation of M(61
), and in some cases, the lid (61)
However, if the winding direction of this embodiment is used, the spiral body (30A) may be damaged as the separation tube (29) rotates, causing the lid (61) to fly off. Since the force acts in the direction of expanding the diameter of the cylinder and contracting the length in the axial direction of the cylinder, there is no such drawback, and the locking structure of the lid (61) can be simplified.

The lid (61) is fitted and locked inside the large diameter portion (60) at the upper end of the cylindrical portion (29b) as shown in FIG. 4 and FIGS. Features and filters (
30) is configured to function as a means for preventing debris accumulated on the inner circumference from flying out. (61a) is a filter (
30) A hanging ring body located outside the upper end, with protrusions (85)... provided at equal intervals on the outer circumferential surface, and these protrusions <
Consisting of a vertical groove (86a) through which the projection (62) of the large diameter portion (60> passes) between the 85> (85) and a lateral groove <86b) that communicates with this groove (86a) and is engaged by the projection. A large number of shaped grooves (86) are formed at equal intervals, and the inner circumferential portion (87
) is formed in a tapered shape that expands downward, and the vertical protrusion <88) is in contact with the outer periphery of the upper end of the spiral body (30A).
・ is formed, and a liquid flow gap (8
9). In addition, liquid flow gaps (90) and (91) are also formed between the inner surface of the large diameter portion (60) and the hanging ring body (61g>. (61b> has a diameter smaller than the inner diameter of the spiral body (30A>). An opening (
93), and the lower surface forms the filter (30
), and the peripheral edge of the opening (93) acts to prevent the debris from popping out.

Also, referring to FIG. 2, the container lid <21b) is cutter (
A material input tube (44) is integrally installed vertically so as to face an off-center portion of the cutter (38).
A regulating plate 41) is integrally provided so as to protrude horizontally so as to cover substantially the entire surface of the plate. The outer edge of the regulating plate (41) is bent downward and positioned outside the re-cutting blade (40) to form a hanging portion (41a) facing the extending portion (42). [There is. This hanging part (41a) is formed with one or more slits for concentrating the material and making it pop out, and a protrusion (94) for holding down the cut material is formed on the outer peripheral surface.
...are integrally formed. <95> is the material input tube (
41) A push rod inserted into the interior to push the material, (96).
- is a protrusion formed diagonally in the direction to discharge the excess waste out of the separation cylinder when excessive waste is accumulated.

In addition, the container lid (21b>) is attached to the main body case I as shown in FIG.
A day + w-1-L+, h J+-7+ = +

(21a) is held in a closed state and pressed onto the main body case (2).

(III) Regarding the liquid extraction part (C), (119) is a cup for receiving the liquid from the outlet (25), which has a substantially triangular cross section and is formed into a substantially triangular planar shape at the front corner of the main body case (2). A handle (120) is provided at a corner to facilitate removal from the front side of the main body.

Next, the operation of the above embodiment will be explained. Before starting the liquid production, after fitting the protrusions (72) (72) at the starting end of the filter (30) in the extended state as shown in Fig. 6 into the grooves (73) (73), (29b). Then, the lid (61) is attached to the cylindrical portion (29b) while allowing the pulley (30) to be compressed.
) into the large diameter part (60) of the lid (6
1) clockwise when viewed from above and in the opposite direction to the rotational direction of the separation tube (29), the protrusions (62)... are inserted into the horizontal grooves (8).
6b) By positioning it in the deep part of..., the cylindrical part (29b)
join to. In this state, the filter (30) is contracted as shown in FIG. 4 to prevent it from popping out. A gap (79) is created 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 created by the projections (81). , and the projections (82) at the lower end, the gap (80) is maintained at a constant interval. At the same time, the protrusion (59)... and the groove 83 at the bottom end)

9b), and the protrusion (84)... and the groove (8
3) When the upper end of the filter (30) is engaged with the lid (
61), the filter (30) is prevented from rotating at the top and bottom.

Next, the container lid (21b) is closed on the receiver (21a), and the clamping device (97) is rotated to engage the lid (21b) to complete the liquid generation preparation state.Then, the electric motor is driven. Then, put ingredients such as fruits and vegetables into the input tube (44) and push them in with the push rod (95).
9), but large materials such as leather that could not be grated and cut are cut into small pieces by the re-cutting blade (40>...), and then cut into pieces by the regulating plate <41> and the base part (29a). The material to be cut is blown horizontally outward from the gap or notch in the hanging part (41a) and adheres to the inner periphery of the filter (30). While descending along the cylindrical portion (29), it is separated into a waste portion and a liquid portion.
b) After reaching the inner periphery and moving upward through the flow gap (58) formed by the protrusions (57)..., the flow between the lid (61> and the cylinder part (29b) Gap (90) (
91) and flows out of the separation tube (29) into the container (21a).
You can receive it at This liquid flows down from the outlet (25) and is received by the cup (119).

On the other hand, the waste is sequentially accumulated from the inner lower end (H) of the filter (30) while being held down by the holding projection (41a), resulting in an accumulation state as shown in FIG. 13. When the material is further cut, the material to be cut is also accumulated in the inner upper half of the filter (30), and the liquid separated from the material to be cut in the lower part of the horizontal part (61b) of 1 (61) is deposited in the gap ( 79)-(89)-(
90)-(91) and (69)-(90)-(91) and flows out of the separation cylinder (29). This liquid outflow is made smooth by tapering the inner peripheral surface (87) of the hanging ring (61a) of the lid (61). 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).

During this juice generation, the debris adhering to the inner periphery of the filter (30) tries to expand the liquid outflow gap (69) due to centrifugal force, but the upper end of the filter (30)
Because it is held down by As a result, the waste is prevented from flowing out of the filter (30) through the gap (69),
A large amount of waste does not get mixed into the liquid.

To remove the residue after such juice production, first stop the electric motor, remove the clamping device, and remove the container lid (21b).
>Remove. Then, rotate the lid (61) to
When the filter (30) is released from the connection with (b), the filter (30) expands due to its own elasticity as shown in FIG. 13, and its upper end protrudes higher than the upper end of the cylindrical portion (29b). By holding this protrusion and pulling it upward, the filter (30) can be easily taken out of the separation tube (29).This filter (30) has debris (K) attached to the lower part of its inner periphery. filter (3)

In addition, 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.

Also, in order to clean the inside of the separation tube (29), use the stand (29)
a) and the connector (11), and remove the separation tube (29).
) After removing the ring body (2), you can wash the inside with water.
9c) from the base (29a) and separate the base (29a) and the cylindrical part (29b), thereby making cleaning the base part (29a) easier.

In the embodiment configured as described above, the filter (30
) is not provided with a part C1 to prevent debris from flying out upwards, it is possible to eliminate the vertical directionality of the filter (30), prevent misuse, and prevent the filter (30) shown in FIG. Sideways shifting operations can be easily performed.

It should be noted that the present invention is not limited to the above embodiment, and for example, as shown in FIG. 15, the above lid (61) and filter (
30) may be integrally formed. In this case, the liquid flow gap (90') (91
') and the outer periphery of the upper end of the cylindrical part (29b'),
An engaging portion (100) is formed to fit together, and a hanging ring body (61) is formed.
By expanding the inner circumferential surface (87') of a') downward, the outflow of the liquid is made smooth.

Further, by expanding the upper end inner circumferential surface (101) of the filter section (30') downward, it is possible to prevent liquid from accumulating on the lower surface of the lid section (61'). Further, the relationship between the winding direction of the filter (30) and the rotation direction of the separation # (29) may be reversed. Further, the filter (30) may be configured to be in the most contracted state when no force is applied. Furthermore, a filter (30
The spiral body (30A>) may be formed hollow, and the cross-sectional shape may be a shape other than that shown in the drawings. In the case of this hollow formation, the spiral body <30A> can be formed by extrusion molding. Although it is desirable that the projections (81), . . . (82), .

(f) Effects of the Invention According to the present invention configured as described above, the interval of the liquid flow gap can be greatly changed by expanding and contracting the spiral body in the direction of the cylinder axis or by shifting it in the direction perpendicular to the cylinder axis. This makes it easy to separate the debris 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. can be kept. In addition, since the inner peripheral surface of the hanging ring of the filter holding means is expanded downward, the squeezed liquid at the upper end of the filter flows smoothly out of the separation cylinder, reducing the amount of juice squeezed. It has great effects such as being able to increase the amount of water.
