Description

Detailed Description of the Invention (a) Industrial Application Field The present invention relates to a centrifugal separation tube that has a force for cutting materials at the inner bottom and is rotated by a motor, and a centrifugal separation tube that is attached to the inner circumference of the separation tube. The present invention relates to a juicer that includes a cylindrical filter that separates cut material into waste and liquid, and stores 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 and accumulates on the inner circumferential surface. To remove this adhered debris, the filter is elastically deformed, but the change in the spacing between the slits due to this deformation is relatively large ν\ 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 juicers themselves are discouraged from using the juicer itself.

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

(D) Structure of the Invention The structure of the present invention includes a centrifugal separation tube with an open top surface that has a cutter on the inner bottom for cutting the material and is rotationally driven by a morph, and a centrifugal separation tube that is removably attached to the inner circumference of the separation tube to cut the material. In a juicer equipped with a cylindrical filter for separating a waste material into a waste component and a liquid component, the cylindrical filter is constituted by a spiral body having a spiral fluid passage gap whose interval can be enlarged, and the cylindrical filter is A filter retaining lid is provided above the filter and is detachably attached to the north end of the separation tube, and the depth of the separation tube is adjusted so that the upper end of the cylindrical filter protrudes outward from the upper end of the separation tube when the filter retaining lid is opened. It is characterized by having 7 dimensions.

Due to this configuration, waste particles land and accumulate on the inner periphery of the filter, but by expanding and contracting this 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 can be reduced. Since the value changes greatly, the dregs can easily be removed from the filter, and if the filter is washed while changing the interval between the gaps, the dregs caught in the gaps can be easily washed away. Moreover, since the upper end of the filter protrudes upward from the separation cylinder when the filter holding lid is removed, the filter can be easily removed.

<56) is the cylindrical part (29b) into which the filter (30) can be attached.
) 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. A liquid flow gap (58) is provided between the filter (30) and the outer peripheral 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 the filter (30) from rotating, and is 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 (30) instead of forming protrusions on the inner circumferential surface (56).

(60) is a large-diameter portion formed at the upper end of the inner circumferential surface <56>, and a locking protrusion <62) of the lid <61> to 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 cover (66〉) to form a sealed space, and an appropriate number of longitudinal resistance plates (67) are integrally provided in this space protruding from the outer wall (65〉 side). At the same time, an appropriate 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 the inner end of the lower surface of the bottom step portion 52). The outer wall (65) has a tapered shape with a larger diameter at the bottom, making the lower part of the sealed space wider than the upper part. and liquid (
68) is concentrated downward to prevent 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 between each stage. A gap (69) is formed and has spring properties.

This helical body (30A) is molded with a mold so that the gap (69) becomes the wavelength 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 becomes even larger.
When a force is applied in the horizontal direction, a horizontal shift occurs between the steps, and this also causes the distance between the gaps (69) to become wavelength in the left-right direction. This spiral (30A>
What is the length in the crane axis direction? <61) Even in the closed state and the naturally extended state, the depth of the cylindrical part (29b) is longer than 21), making it easy to take out the filter (30>.And, in the naturally extended state of the spiral body (30A>) The length in the axial direction of the cylinder is such that when stored in the separation cylinder (29), the upper end is the container lid (2).
1b>.

In addition, the end surfaces (70) (70) of the top stage (30a) and bottom stage (30b) of the spiral filter (30) are flat surfaces with no steps (excluding the protrusions (82)... described later). With this configuration, a large gap is not formed between the inner surface of the lid (61) and the inner bottom surface of the cylindrical portion (29b), thereby preventing a large amount of debris from flowing out. The height dimension of the above cross section can be changed by gluing ring-shaped bodies for height adjustment on the top and bottom surfaces of the spiral body with the same cross-sectional shape, or by changing the cross-sectional shape with a mold. However, in this embodiment, the latter is adopted. Then, the thickness of the end portions (71) (71) in the cylindrical axial direction is balanced to ensure the strength of the end portions, and the end portions (71) are
71) A protruding piece (72) is provided on (71), and the end (71)
A groove (73) into which the protruding piece (72) is fitted is formed on the mating surface corresponding to (71), and a slight force is applied to the end (71) (71) when the filter (30) is pulled up. The corners are designed so that the ends (71), which have small cross sections, are not damaged even if the projecting piece (72) and the groove (73) are unlatched when a force exceeding a predetermined level is applied. An R is formed in the part. Since this locking is performed on the outer peripheral side of the filter (30), there is less adhesion of debris and cleaning is easy.

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 peripheral surface (75) has a tapered surface (75 a
) (75a), the rotation of the separation tube (29) causes the scum to be accumulated from below first, and also facilitates the removal of the scum from the filter in the downward direction. In addition, in the embodiment, in order to eliminate the vertical directionality of the filter (30),
Although it is formed to have a larger diameter toward the top and bottom, if it has directionality, it may be formed into a tapered surface that becomes thicker from the top toward the bottom.

In addition, the cross-sectional shape of each stage of the spiral body (30A) is such that the upper and lower corners of the outer surface are notched (76a>(76a)
)1. This reduces the flow resistance of the liquid flowing out from the gap (69), and makes the inner surface (76b) a flat surface to facilitate the movement of waste. Note that the form of this 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 has a lower surface (!(61)). , a liquid flow gap (
79) (80>). This gap is formed in the spiral gap II! (69) so that the gap between each stage does not become narrower than a certain value (for example, 0.4 mm) in the closed state of the figure. is the flat surface (
77b) are formed with spacing projections (81) of the same height over substantially the entire width in the radial direction at equal intervals in the longitudinal direction of the gap (69). )
In this case, there are protrusions (
Protrusion for maintaining the distance at the same height as 81)... (82)...
is formed. These protrusions <81)・ , (82)
・The ease with which liquid flows out is approximately equal throughout the vertical direction of the filter. Incidentally, the latter protrusions (82>... are provided on the lid (61) and the cylindrical part (
29b) side, and the former protrusion (81) ridge may be provided on the upper surface side of the spiral body (30A). Also, the protrusion (8
1). , (82>... may be a knurled projection.

Also, upper XQ spiral body (30A) i: Ha cylinder m (29
b) and U'Ili (61), rotation is prevented by a concave-convex engagement. That is, in the upper and lower outer corners of the spiral body (30A), substantially ■-shaped engagement grooves (83) of the same shape are formed at a predetermined angle of about 60 degrees in this example. A large number of them are formed over the range, and a pair is formed at the target position, and a lid (6
1) at a predetermined angle (approximately 60° in this example)
When the roughly ■-shaped protrusions (84) formed at intervals of 300 mm fit together, the rotation stopper is lost between the lid (61) and the grooves (83) at the lower end. By fitting the protrusions (59) of the cylindrical portion (29b), rotation is prevented between the cylindrical portion (29b) and the cylindrical portion (29).

Moreover, - the above spiral body (30A>
29b) and set so that when the separation cylinder (29) is rotated, the diameter will expand.
) is formed so that when the rotation direction is counterclockwise (x) when viewed from above, the winding direction from top to bottom is clockwise when viewed from above. If you wind it in the opposite direction to this winding direction, the lid < 6
Since there is some play in the engagement between 1) and the filter (30), as the separating tube (29〉) rotates, the diameter of the helical body (30A〉) contracts, and at the same time, a force is applied in the direction that the length in the axial direction of the cylinder increases. acts,
This force becomes a force that tries to remove the lid (61), and in some cases, there is a risk of damaging the engagement part between the lid (61) and the separation cylinder (29) and causing the lid (61) to fly off. If the winding direction of the embodiment is used, the spiral body (30
In case A), the force is applied in the direction of increasing the diameter and decreasing the length in the axial direction of the cylinder, so there is no such drawback and the locking structure of the lid (61) can be simplified.

Further, the lid (61) is fully fitted into the large diameter portion (60) at the upper end of the cylindrical portion (29b) as shown in FIG. 4 and FIGS. 10 to 12, thereby preventing the filter (30) from being removed. and filter (30)
The structure is designed to prevent debris accumulated on the inner circumference 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 (85) (85), the large diameter part (60)

) are formed at equal intervals, and the inner circumferential surface (87) is formed in a tapered shape that expands downward, and a longitudinal protrusion that abuts the outer periphery of the upper end of the spiral body (30A) is formed. A liquid flow gap (89) is formed between the thread (88) and the spiral body (30A).
) There is also a liquid flow gap (90) between the inner surface and the vertical part (61a).
) (91) is formed. (61b) is a spiral (3
The horizontal part has an opening (93) with a downward protrusion (92) on the /ifl edge with a J-diameter smaller than the inner diameter of the filter (3o), and the lower surface presses the upper end surface of the filter (3o) and the opening <93 ) prevents debris from flying out.

Also, referring to FIG. 2, the container M (21b) is subjected to a force ν (
A material input tube (44) is integrally installed vertically so as to face an off-center portion of the tube (38), and a regulating plate (41) is attached to the periphery of the tube (44) so as to cover almost the entire surface of the tube (38). It protrudes horizontally. The outer edge of the regulating plate (41>) is bent downward to form a hanging part (41g) located outside the recutting blade (4o) 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 is also integrally formed with projections (94) for holding the material cut on the outer circumferential surface. (95) is a push rod that is inserted into the material input tube (41) to push the material, and (96)... is a push rod that is used to discharge excess waste from the separation tube when excessive waste is accumulated. It is a ridge formed diagonally.

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

(III) About the liquid take-out part (C) The part (119) receives the liquid from the outflow port (25). It is placed on a triangularly formed low step part (9), and a handle (120) is provided in the hooker part to facilitate removal from the front side of the main body.

Next, the operation of the above embodiment will be explained. Before liquid generation, after engaging the protrusions (72) (72) at the starting end of the filter (3o) in the extended state as shown in FIG. 6 with the grooves (73) (73), the neck (29b) Attach it inside. Then, without compressing the filter (30), lti (61) cylinder 8B
(29b) is fitted into the large diameter portion (60), and the protrusion (62
)... from the vertical groove (86a>...) into the horizontal groove (86b), and when looking at the lid (61), insert the separation tube (29) in the backward direction.
) in the direction opposite to the direction of rotation of the protrusion (62)...
By positioning the cylindrical part (
29b). In this state, the filter (30) is shrunk and protrudes to form an adjacent chamber as shown in FIG. There is a gap (79) between the inner surface of the lid (61) and the upper end surface (70) of the filter (30) due to the projections (82>) on the upper end.
), the gap (69) is maintained at a constant interval by the protrusions (81), and the gap (80) is maintained at a constant interval by the protrusion (82) at the F end. At the same time, the protrusion (59)... and the lower end tR<
s3)..., the lower end of the filter (30) is locked to the cylindrical part (29b), and the protrusion (84)... and the groove (
83)..., the upper end of the filter (30) is locked to the lid (61>), and the filter (30) is prevented from rotating vertically.

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. The drive drives materials such as fruits and vegetables into the input cylinder (44) and pushes them in with the push rod (95).Then, the materials are grated by the grating blade (39), but the peels that could not be grated and cut are removed. For large materials such as, re-cutting blade (to')...
It is cut into pieces by the horizontal external force through the gap between the regulating plate (41) and the base (29a) or the notch in the hanging part (41a), and adheres to 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 separating cylinder (29>) through the flow gap (90) (91) between the lid (61) and the cylinder part (29b). The liquid is received in the container (21a).This liquid is received at 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 upper inner 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)-(
90)-(91) and (69)-(9o)-(9i) to the outside of separation M (29).This liquid flows out by tapering the inner peripheral surface (87) of the lid (61). Furthermore, when the material is cut and accumulated inside the opening (93) of the lid (61), the scraps are separated by the protrusions (96) M (29). Expelled 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 (3O) = lid (61)
), this distance does not widen and remains constant. As a result, the debris is in the gap (69)
The flow out of the filter (30) is suppressed through the
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.
). Then, rotate the lid (61) to
When disengaged from the filter (30), the filter (30) expands due to its own elasticity as shown in Fig. 13, and its upper end protrudes above the upper end of the cylindrical portion (29b).Hold this protrusion and pull it upward. Therefore, the filter (30) is placed outside the separation tube (29).
＼It can be taken out easily. This filter (30) has debris (K) attached to the lower part of the inner circumference, and the filter (30)
By holding both ends of the filter 30> and expanding and contracting it and shifting it laterally as shown in FIG. 14, the mass of waste (K) can be easily removed from the inner periphery of the filter. In addition, fibers etc. remaining in the gap (69) can be easily removed by washing with water in this expanded state, since the gap (69) interval is modified by its own elasticity.

Also, in order to clean the inside of the separation tube (29), use the stand (29)
a) and the funecta (11), and remove the separation cylinder (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), making the cleaning even easier.

In the above embodiment, the spiral body (30A) is connected to the separation tube (2
9) The spiral body (3
By imparting spring properties to the filter (30), the liquid flow gap (69) expands when the filter (30) is taken out, making it easier to remove debris and clean it. When the upper end of (30A) comes into contact with the container lid (21b>), the lid (61
) has the advantage that if you forget to close the door and drive the machine by mistake, a contact noise will be generated and you will be able to easily notice the abnormality.

Moreover, since the filter (30) protrudes upward from the upper end of the cylindrical part (29b) when installed in the cylindrical part (29b) and when the lid is opened, the filter (30) can be easily taken out. Furthermore, by forming a large-diameter portion (60) at the upper end of the cylindrical portion (29b) and having a space between it and the outer periphery of the upper end of the filter (30) so that a finger can be inserted, the filter (30) can be easily inserted. It is easier to take out the filter, and the filter (30
) can be seen at a glance whether the filter (30) is attached to the cylindrical portion (29b), thereby preventing misuse due to the filter (30) not being attached.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and for example, 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 this hollow case, the spiral (
30A> can be formed by extrusion molding. or,
The concave groove (57) of the cylinder part (29b) is the bottom
(not shown) is formed on the filter (30) and the protrusion (57) is formed on the filter (30).
... can also be used to prevent the filter from rotating. Further, the protrusions (57) may be discretely formed protrusions.

Effects of the Invention According to the present invention configured as described above, the interval of the liquid flow gap can be increased by expanding 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 waste from the filter, and it also makes it possible to clean the filter with a large liquid flow gap, making it easy to clean the filter and always keep the filter clean. Can be kept clean. In addition, since the upper end of the filter projects upward from the upper end of the separation cylinder when the lid is opened, the filter having this projecting part can be easily taken out, which has great effects such as facilitating waste removal work.
