Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention comprises a centrifugal separation cylinder which has a cutter on the inner bottom for cutting the material and is rotated by a motor, and a centrifugal separation cylinder which is attached to the inner circumference of the separation cylinder and which cuts the material. The present invention relates to a juicer that includes a cylindrical filter that separates crushed material into waste and liquid, and stores the waste in a centrifugal separation cylinder.

(b) Prior Art This type of Juner is known, for example, from Japanese Utility Model Publication No. 58-10504. The filter used in this juicer is formed into a comb-like shape to form a large number of vertical liquid outflow slits, and one piece of waste is accumulated on the inner periphery of the filter. In order to remove the adhered debris, the filter is elastically deformed, and the change in the spacing between the slots 71- 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 the scum has been the main reason why people are reluctant to use the juicer itself.

(c) Purpose of the Invention In view of the above drawbacks, an object of the present invention is to provide a juicer that is easy to use by making it easier to remove waste and also to make it easier to attach a filter.

(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. The juicer is equipped with a cylindrical filter that separates waste and liquid, and the waste is transferred into the centrifugal separation cylinder, and the cylindrical filter is provided with a spiral liquid flow gap whose interval can be expanded. The upper and lower end surfaces of the spiral body are formed into substantially flat surfaces by avoiding a change in the cross-sectional shape of the final stage of the spiral body, and the inner bottom surface of the centrifugal separation cylinder, which the lower end surface of the spiral abuts, is formed into a substantially flat surface. It is characterized by being formed in the form of

Due to such a configuration, waste particles land and accumulate on the inner periphery 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 liquid fAE passage gap can be reduced. Since the spacing changes greatly, the scum can be easily removed from the filter, and if the filter is washed with the gap widened, the scum caught in the gaps can be easily washed away. Furthermore, since the upper and lower end surfaces of the filter are formed to be flat surfaces, the cylindrical filter can be mounted in the separating cylinder without any consideration of the mounting position in the rotational direction.

The cutter (38) is attached to the horizontal part (31) by caulking with screws or rivets, and forms grating blades (39) as cutting blades radially from the center, and also scrapes the remaining material by cutting the periphery. A plurality of recutting blades (40) for finely recutting are formed.

The cylindrical portion (29b) is made of synthetic resin and has a bottomed cylindrical shape with an opening at the top as shown in FIG. The outer periphery is a low stage part (52) for collecting waste.The high stage part (46) has its outer periphery (46a) facing downward in order to facilitate the separation of the waste accumulated on the low stage part (52). A cylindrical fitting part (47) into which the support part (32) of the stand part (29a) fits is formed in the center part, and the upper end part of the support part (32) (32a) Bring the outer periphery into surface contact with the upper inner circumferential surface (47a) of the fitting part (47), and bring the outer periphery lower surface (31a) of the horizontal part (31) into surface contact with the upper surface (46a) of the high step part (46).
Face contact is allowed. This two-face contact between the horizontal and vertical surfaces reliably prevents the base portion (29a) and the cylindrical portion (29b) from shaking, and also improves the support strength.

) has a tapered shape with a larger diameter at the top so that the separated liquid can easily rise, and a plurality of vertical protrusions (57) are formed at appropriate intervals. However, a liquid flow gap (58) is provided between the filter (30) and the outer circumferential surface of the filter (30).

(59)... is a filter locking protrusion formed on a part of the lower end corner of the inner peripheral surface 56), which prevents rotation of the filter (30), 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 a protrusion (not shown) on the outer circumference of the filter (30) instead of forming a protrusion on the inner peripheral surface <56>.

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

(63) is a fluid balancer formed in an abbreviated shape over the side and bottom surfaces of the cylindrical portion (29b). The opening is closed with a ring-shaped bottom lid (66〉) to form a sealed space, and within this space, an appropriate number of vertical resistance plates (67) are protruded from the outer wall (65〉 side) and the body. At the same time, an appropriate amount of balancer liquid (68) is sealed in this space.The bottom cover (66) has an uneven fit between the lower end of the outer wall (65) and the inner end of the lower surface of the bottom step (52>). The outer wall (65) is tapered and has a larger diameter at the bottom, making the lower part of the sealed space wider than the upper part. ,liquid(
68) is concentrated downward to prevent the liquid from rising upward.

As shown in FIGS. 7 to 10, 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 a spring property. When this spiral body (30A> is in a state where no force is applied in the direction of contraction in the direction of the cylinder axis (natural extension state wM), the gap (69) is formed as shown in Fig. 7. It is molded with a mold so that it is in an expanded state, and when the lid (61) is closed, it is compressed and the gap < 69) becomes the most contracted state. When force is applied to -m gap (6
The gap 9) has a wavelength, and when a force is applied in the horizontal direction, a lateral shift occurs between the steps, which also causes the gap 69 to change the wavelength in the left-right direction. This spiral (30
The length of A> in the axial direction of the cylinder is longer than the depth ρ1 of the cylinder part (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 final stage (30a) (30
b) The ends (70) (70) are flat surfaces with no steps (in addition,
(excluding protrusions (82)... described later) prevents the formation of a large gap between the lower surface of the lid (61) and the inner bottom surface of the cylindrical portion (29b), thereby preventing the outflow of waste. ing. To change the height dimension of the above cross section,
This is possible by gluing separate ring-shaped bodies for height adjustment to 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. ing. Then, the end portions (71) (71) are made sufficiently thick in the axial direction of the cylinder to ensure the strength of the end portions, and the end portions (71) (71)
1) is provided with a protruding piece (72), and a groove (73) into which the protruding piece (72) is fitted is formed on the outer circumferential side of the abutting surface corresponding to the end (71>(71)). The structure is designed so that even if a small amount of force is applied to the ends (71) (71) when pulling up the router (30), the ends (71) (71) having a small cross section will not be damaged, and the structure is such that the ends (71) (71), which have a small cross section, will not be damaged. A radius is formed at the corner so that the protrusion (72) and the groove (73) become unlatched when activated.Since this locking is done on the outer circumferential side of the filter (30), it prevents the adhesion of debris. It is small and easy to clean.

In addition, 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)...), and the outer peripheral surface (74) is in contact with the protrusions 57〉... At the same time, the inner circumferential surface (75) extends upward from the midpoint (0) as shown in FIG.
The tapered surface (75
a) (75a), the rotation of the separating cylinder (29) allows the scum to accumulate from the lower blade and facilitates the downward removal of the scum from the filter.

Also, the shape of the helical body (30A>) with a break in each stage -!;
As shown in Figure 10, cut out the upper and lower corners of the outer surface (76a)
(76a) This reduces the flow resistance of the liquid flowing out from the gap (69), and the inner surface (76b)
is used as a flat surface to facilitate the movement of debris. Note that the form of the notch is not limited to that shown in the drawings. Moreover, if C is good without improving the mobility of the dregs, the inner side rIIi may be made into a curved surface.

Further, referring to FIG. 4, the spiral body (30A) forms liquid flow gaps (69) between each stage, and also forms flat surfaces (77a) (77b) on the surfaces forming the gaps. (61) A liquid flow gap 79) (80) is formed between the lower surface and the upper surface of the low step <52> of the cylindrical portion (29b). When the lid is closed in the figure, the gap between each stage is a constant value (for example, 0.411n).
) In order to prevent the spiral gap (69) from becoming narrower than 81 mm, the flat surface (77b) of the lower surface of the spiral body (30A), which is the gap-constituting surface, is provided with gap-maintaining protrusions of the same height over substantially the entire width in the radial direction. >... are formed at equal intervals in the longitudinal direction of the gap (69), and the gaps (79) (80)
In this case, there are protrusions (
81) Protrusion for maintaining the same height as the spacing (82)...
is formed. These protrusions (81)..., (82
〉... makes the ease of liquid outflow approximately equal over the entire vertical direction of the filter. Incidentally, the latter protrusion (82) is provided on the lid (61) and the cylindrical portion (30A) instead of being provided on the spiral body (30A).
29b) side, the former protrusion (81)...
may be provided on the upper surface side of the spiral body (30A). Further, the projections (81>..., (82)) may be knurled projections.

Further, the helical body (30A) marked -F is prevented from rotating by engaging the concave and convex portions between the cylindrical portion (29b) and the lid (61). 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).
A large number of... are formed over a predetermined angle range (approximately 60 degrees in this example) in pairs at symmetrical positions, and the upper groove (83) is filled with the inside of the lid (61). The lid (
61), and the groove at the lower end (83)
By fitting the protrusion (59) of the cylinder part (29b) into the separation cylinder (29), rotation is prevented.
8.

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
It is formed so that the direction of winding is the clockwise, JJ direction when viewed from above.If the winding is reversed to this direction, the diameter of the spiral body (30A> will shrink as the separation cylinder (29) rotates. At the same time, a force acts in the direction in which the length in the axial direction of the cylinder increases, and this force becomes a force to remove 1 (61), and depending on the case, There is a risk of damaging the engaging part and causing the lid (61) to fly off, but if the winding direction of this embodiment is used, the rotation of the separation cylinder (29) will require a spiral body (30A)
Since the force acts in the direction of enlarging the diameter and reducing 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.

Further, the lid (61) is fitted and locked inside the JZ end large diameter portion 60) of the hn-i hook (29b) shown in Fig. 4 and Figs. Stop and filter (3
0) has a function of preventing debris accumulated on the inner periphery 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 between the protrusions <85085), the large diameter part (60)
), a longitudinal groove (813a) through which the protrusion (62> passes) and a transverse groove (86a) that communicates with this groove (86a) and is engaged with this protrusion
b) A large number of "shaped grooves (86)" consisting of Abutting longitudinal protrusions (88〉) are formed, and a spiral body (30〉) is formed.
A liquid flow gap (89) is formed between the two and A). or,
Liquid flow gaps (90) and (91) are also formed between the inner surface of the large diameter portion (60) and the vertical portion (61a). This liquid flow gap (91) is mainly composed of 7111' (86)... and the groove (100) above it.

<61b) is a horizontal part in which an opening (93) is formed with a diameter smaller than the inner diameter of the spiral body (30A) and has a downward protrusion (92) on the periphery, and a flat lower surface forms a filter <30>.
At the same time, the upper end surface of the opening (93) is pressed, and the periphery of the opening (93) acts as a barrier to trap debris.

Also, referring to FIG. 2, the container lid (21b>) is a cutter (
A material input M (44) is integrally installed vertically so as to face a portion off the center of the cutter (38).
A single regulating plate (41) is provided 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 to form a hanging part (41a) located outside the recutting blade (40) and facing the extending part (42). This hanging part (41a) is formed with one or more slits for concentrating the material and protruding from it, and there are projections (94) cut on the outer circumferential surface for holding down the material...

A push rod inserted into the interior to push the material 1. , (96)...
- is a protrusion formed diagonally in the direction to discharge the excess waste out of the separation cylinder when excessive waste is accumulated.

2. The container lid (21b) is attached to the main body case (21b) as shown in Figure 1.
The clamp device (97) attached to the container (21)
a) is pressed onto the main body case (2) with the lid closed.

(I[[) Regarding the liquid take-out part (C) (119) is a cup that receives the liquid from the outflow port 25).

It has a roughly E-angular cross section and is placed on a low step part (9) formed in a roughly triangular planar shape at the front corner of the main body case (2), and a handle (120) is provided at the corner. This makes it easy to take out from the side.

Next, the operation of the above embodiment will be explained. Before performing liquid generation, the protrusions (72) (72) at the starting end of the filter (30) in the extended state as shown in Fig. 7 are inserted into the grooves (73) (as shown in Fig. 9).
73) and then installed into the cylindrical portion (29b).

Then, while compressing the filter (30), remove the lid (61).
into the large diameter part (60) of the cylindrical part (29b), insert the protrusion (62) from the vertical groove (86a) to the horizontal groove (86b), and turn the lid (61) clockwise when viewed from above. Separation cylinder (29
) in the opposite direction to the direction of rotation of the protrusion (62).
... is connected to the cylindrical portion (29b) by locating it deep inside the horizontal groove (g6b).

In this state, the filter (30) is contracted as shown in FIG. 4 to prevent it from popping out. And the protrusion at the top <82
)... creates a gap (79) between the inner surface of the lid (61) and the upper end surface (70) of the filter (30), and the protrusions (81) and
The gap (69) is caused by the protrusion J (82) at the lower end.
The gap <80> is maintained at a constant interval. At the same time, the engagement between the projection (59) and the groove (83) at the lower end causes the
The lower end of the f-ruter (30) is completely locked to the cylindrical part (29b),
The L end of the filter (30) is locked to the lid (61) by the engagement of the protrusion (84) and the groove (83) on the upper end, and the filter (30) is prevented from rotating at the top and bottom. Ru.

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 juice liquid production preparation state.Then, the electric motor is turned on. It is driven to feed materials such as fruits and vegetables into the input cylinder (44) and push them in with the push rod (95).Then, the materials are grated by the grater blade 39), but the material cannot be cut by 4-grating. For large materials such as leather, use the re-cutting blade (40)...
The particles are cut into small pieces, and are blown outward in the horizontal direction through the gap between the regulating plate (41) and the base (29a) or the notch in the hanging portion (41a), and are deposited on the inner periphery of the filter (30>).

This adhered cut material descends along the tapered surface (75a) of the filter (30) and is separated into scraps and liquid, and the liquid flows through the gaps (80) and (69). reaches the inner periphery of the cylindrical part (29b), and the protrusion (57)...
After moving upward through the flow gap (58>) formed by the above, it flows out of the separation tube (29) through the flow gap (90) and (91) between the lid (61) and the cylinder part (29b). This liquid is received in the container (21a) through the outlet (25).
) and is received by the cup (119).

On the other hand, the waste portions are accumulated sequentially 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 the lid 61> is accumulated in the gap ( 79)-<89)-(
It flows out of the separation cylinder (29) through 90)-(91) and (69)-(90)-(91). The outflow of this liquid is made smooth by tapering the inner circumferential surface (87) of the lid 61). Further material is cut; it (6
When the waste is accumulated inside the diameter of the opening (93) of
It can be drained outside.

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), and a large amount of waste is prevented from being 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 disengaged from the cylindrical portion (29b), the filter 30> expands due to its own elasticity as shown in FIG. 14, and its upper end protrudes in three directions beyond the upper end of the cylindrical portion (29b). Holding this protrusion and pulling it to one side, the fill h (30) is removed from the separation cylinder (2).
9) Can be easily taken out. This filter (3
0) has 11 pieces of waste (K) on the lower part of the inner periphery, and by holding both ends of the filter (30) and expanding and contracting it, and shifting it laterally as shown in Figure 15, the pieces of waste can be removed. The mass (K) easily separates from the inner periphery of the filter. In addition, the m-fibers and the like remaining in the gap (69) can be easily washed away by washing with water in this expanded state, since the gap (69) waveforms 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), which makes cleaning the base part (29a) even easier.

In the configuration of the above embodiment, the negative end surfaces (70) (70) of the spiral body (30A>) are flat surfaces, and the lower surface of the lid (61) and the separation M to which the upper and lower end surfaces (70) (70) abut, respectively, are made flat. By making the inner bottom surface of (29) a flat surface, the spiral body (30A), the lower surface of the lid (61) and the separating tube (29)
) and the inner bottom surface of the liquid flow gaps (79) and (80) are kept constant over the entire rotational range. This gap (79) (80) is maintained by a spiral (30A>
If the shape of the final stage is not changed, a step will be formed at the final stage,
To prevent a large amount of waste from flowing out from this step, a spiral (30
It is necessary to maintain a constant gap in the liquid flow gap by forming a step groove (not shown) into which the step portion of A> fits, but if this is done, the separation cylinder (29) of the filter (30)
) is limited to one location in the rotational direction, and the lid (61) is also limited to one location, making it extremely difficult to install the filter (30) and the lid (61>). However, with the configuration of the embodiment, certain drawbacks can be overcome.

Further, as a method of changing the thickness in the cylinder axis direction of the final stage (30a) (30b') of the spiral body (30A), it is also possible to sequentially change the thickness of the final stage so that the thickness at the end becomes zero. In this case, there is a disadvantage that the terminal end becomes sharp, which is dangerous, and the strength of the terminal end is weakened. However, these disadvantages can be overcome by making the geta cover the thickness of the terminal end as in the above embodiment.

Furthermore, since the terminal ends (71) (71) are engaged at the abutting portions, when the filter (30) is taken out, the weight of the accumulated waste and the weight of the filter (30) are removed from the uppermost stage (30a). However, this weight will not cause the filter (30) to extend too much in the axial direction of the cylinder or damage the thin end. This point also applies to the bottom row (30b). Moreover, when cleaning the filter (30), cleaning can be facilitated by disengaging the terminal end.

It should be noted that the present invention is not limited to the above embodiment, and for example, the relationship between the winding direction of the filter (30) and the rotation direction of the separation tube (29) may be reversed. Also, filter (30
) may be configured so that it is 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 of a shape other than that shown. In this case, the spiral (30A>) can be formed by extrusion.

Further, a groove (not shown) that fits with the protrusion (57) of the cylindrical portion (29b) is formed on the filter (30), and the protrusion (57) is formed on the filter (30).
〉 ・It is also possible to use it to prevent rotation of the filter. Further, the protrusions (57) may be discretely formed protrusions.

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 debris from the filter, and also allows cleaning with a large liquid flow gap, making it easy to clean the filter and keep the filter clean at all times. can be kept. In addition, the former lower end surface of the cylindrical filter is made substantially flat, and the inner bottom surface of the separation cylinder is made substantially flat1, and the liquid flow gap is made substantially constant over the entire rotational range, so that when the filter is installed, the rotational direction・It can be installed without any consideration of the installation position of ＼, which has great effects such as ease of installation work.
