Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention consists of a centrifugal separation tube that has a cutter on the inner bottom that cuts the material and can be rotated by a motor; The present invention relates to a juicer that is equipped with a cylindrical filter that separates waste 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. 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 residue, and the residue cannot be removed by simply washing with water, so the residue must be scraped off using a brush or the like, making the task of removing the residue 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 by making it easy to remove the dregs, and also to prevent a large amount of dregs from getting mixed into the liquid. shall be.

(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 circumference of the separation tube to remove the cut material. A juicer comprising a cylindrical filter for separating waste and liquid, and storing the waste in a centrifugal separation cylinder, wherein the cylindrical filter has a spiral liquid flow gap whose interval can be adjusted to a wavelength. It is characterized in that it is constructed of a spiral body and is provided with filter holding means above the cylindrical filter of the centrifugal separation tube.

Depending on the configuration, scum adheres to and accumulates 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 interval of the liquid flow gap changes greatly, so the scum can be removed. If the filter is easily detached from the filter and the filter is washed while changing the interval between the gaps, the debris caught in the gaps can be easily washed away. In addition, when juice is produced, a force is exerted by the waste to widen the gap between the liquid outflow gaps, but the expansion of the gap is suppressed by the filter holding means, preventing a large amount of the waste from passing through the filter and mixing into the liquid. It disappears.

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 that can be formed at the upper end of the inner peripheral surface (56), and a locking protrusion (62) of a 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 lower opening is closed with a ring-shaped bottom cover (66) to form a sealed space, and an appropriate number of vertical resistance plates (67) are integrally protruded from the outer wall (65) (1111) into this space. 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) has a tapered shape with a thicker diameter at the bottom to make the lower part of the sealed space wider than the upper part. ,
The liquid (68) is concentrated downward and prevented 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) becomes the wavelength state as shown in Fig. 6 when no force is allowed to act in the direction of contraction in the direction of the cylinder axis (natural extension state). in,! (61) In the closed state, the compression is complete and the gap (
69) is in the most contracted state, and if force is allowed to act in the direction of extension of the cylinder axis from the state shown in the same figure, the gap (69) will be further reduced.
When the gap (69) is widened and a force is applied in the horizontal direction, horizontal threading occurs between the steps, which also causes the gap (69) to waver in the left-right direction. This spiral (30A>
The length 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).

It is constructed so that the ends (71) (71), which have small cross sections, are not damaged even if a small amount of force is applied to the ends (71) (71) when pulling up the projecting piece. A radius is formed at the corner so that the lock between (72> and the groove (73) can be released.This lock is for the filter <30).
Because it is carried out on the outer periphery of the machine, there are fewer scraps (-1), making cleaning easier.

In addition, the spiral body (30A) has an outer diameter slightly smaller than the inner diameter (tip of the protrusion (57)) of the cylindrical portion (29b), and the outer circumferential surface (74) is in contact with the protrusion (57). and the inner circumferential surface <75) is above the midpoint (0) as shown in FIG.

Good.

Further, the cross-sectional shape of each stage of the spiral body (30A) is as shown in FIG.
a) Due to the shape of L and this, d[ from the gap (69)
The flow resistance of the liquid to be discharged is reduced, and the inner surface (76b) is a substantially vertical 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.

In addition, refer to FIG. 4 [7] The spiral body (30A) forms a liquid flow gap (69) between each stage, and also forms a flat surface (77a> (77b) on the surface constituting the gap, and the lid (61) A liquid flow gap (79) (80) is formed between the lower surface and the upper surface of the low step part (52) of the cylindrical part (29b). is a constant value, for example 0.4mm

> The protrusions (59) of the cylindrical portion (29b) fit together to prevent rotation between the separation M<29).

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 cylinder (29) is counterclockwise (x) when viewed from above, the spiral body (30A) is set so that its diameter increases. The winding direction is clockwise when viewed from above. If the winding direction is opposite to this one, the separation tube <29)
With the rotation of the helical body (30A), a force acts in a direction in which the diameter of the helical body (30A) decreases and at the same time the length in the axial direction of the cylinder increases, and this force acts on the lid (61A).
), and in some cases, the lid (61)
However, if the winding direction of this embodiment is used, the spiral body (30A> 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 shown in FIG. 4 and FIGS. 10 to 12.
The filter (30) is fitted and locked into the large-diameter upper end portion 60) of the cylindrical portion (29b) to remove the filter (30).

b) A large number of "shaped grooves (86)" consisting of A spiral body (30A) is formed with a protrusion (88) in the vertical direction.
A liquid flow gap (89) is formed between the two. In addition, a liquid flow gap (90>(91>) is also formed between the large diameter part (60> inner surface and the vertical part (61a). (61b) has a diameter smaller than the inner diameter of the spiral body <30.A). A horizontal part formed with an opening (93) having a downward protrusion (92) on the periphery, which presses the upper end surface of the filter (30) with its lower surface and acts to prevent debris from flying out at the periphery of the opening (93). .

Further, referring to FIG. 2, the container lid (21b) is integrally provided with a material input cylinder (44) so as to face an off-center portion of the force/meter (38>), and a force is applied to the periphery of the container lid (21b).・Nta<3
A regulating plate (41) is provided as one body and protrudes horizontally so as to cover substantially the entire surface of the housing 8). The outer edge of the regulating plate (41) is bent downward and positioned outside the re-cutting blade (40)... and the hanging part (41a) facing the extending part (42)...

) 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 (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.

(1) Regarding the liquid extraction part (C), (119) is a cup that receives 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 the corner 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 (30) in the extended state as shown in FIG. 6 with the grooves (73) (73), ). Then, while compressing the film (30), the lid (61) is attached to the cylindrical portion (29b).
) into the large diameter part (60) of the lid (61), and insert the projection (62) from the vertical groove (86a) into the horizontal groove (86b).
) clockwise when viewed from above and in the opposite direction to the rotation direction of the separation tube (29), the protrusions (62)... are inserted into the horizontal grooves (86b).
)... is connected to the cylindrical part (29b). In this state, the 7C router (30) is reduced as shown in FIG. 4, and the protrusion β is stopped. 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). However, the gap (80> is maintained at -S interval by the protrusion (82) at the lower end. At the same time, the protrusion (59)... and the groove (83) at the lower end...
When engaged with the lower end of the filter (30), the lower end of the filter (30)
The upper end of the filter (30) is locked to the lid (bl) by the engagement of the protrusion (84) with the upper edge (83), and the filter (30) Rotation is stopped at .

Next, the container lid (21b) is closed on the receiver (21a), and the clamp device (97) is rotated to engage the lid (21b), thereby completing the one-liquid production preparation state. And the electric motor′f:
Drive to feed ingredients such as fruits and vegetables! (44) and push it in with the push rod 95). When you speak, the material is grated blade (
39), but large materials such as leather that could not be grated and cut are cut into small pieces by the cutting blade (40), and cut into pieces by the regulating plate (41) and the base part (29a). The particles fly horizontally outward from the gaps or notches in the hanging portion (41a) and adhere 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). cylindrical part (29
b) After reaching the inner periphery and moving toward the child side through the flow gap (58) formed by the projections (57), the lid (6

) flows out of the separation tube (29) and into the container (21a).
I can receive C. This liquid flows down from the outlet (25) and is received by the boo cup (119).

On the other hand, the waste portions are sequentially piled up M 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 the 13th IA. When the material is further cut, the material to be cut is also accumulated in the internal force of the filter (30), and the liquid separated from the material to be cut in the water mop part (61b >'T side) of the lid (61) is Gap (79) - (8
9)-(90)-(91) and (69)-(90)-(
91) through! It flows out of the i cylinder (29). This liquid leaks out! .

This is done smoothly by tapering the inner circumferential surface (87) of the (61).Furthermore, if the cut material accumulates inside the diameter of the opening (93) of the lid (61), the protrusion (96)..., the waste is discharged to the outside of the separation cylinder (29).

During this juice generation, the inner periphery of the filter (30) (=t
Due to the centrifugal force, the M residue tries to expand the gap between the liquid d and the outlet gap (69), but since the upper end of the filter (30) is held down by the lid (61), this gap widens. 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 waste after producing such juice, first stop the electric motor, remove the clamp 8M, and remove the container lid (21b).
>Remove. Then, rotate the lid (61) and
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). By holding this protrusion and pulling it upward, the filter (30) can be removed from the separation tube (29).
＼You can easily take out the hot water. This filter (30)
There is debris (K) attached to the lower part of the inner periphery of the filter.By holding both ends of the filter (30) and expanding and contracting it, as well as shifting it laterally as shown in Figure 14, the mass of debris (K) can be removed. Easily detaches from the inner periphery of the filter. Also, gap (69)
Since the fibers and the like remaining attached to the gap (69) have their own elastic strength, they can be easily washed away by washing with water in this expanded state.

In addition, to clean the inside of the separation M (29), use the stand (29)
a) and the connector (11), and remove the Pm cylinder (2).
After removing the ring body (9), you can wash the inside with water, but the ring body (
29c) from the base (2, 9a), and remove the base (29a).
By separating the surface portion (29b) from the surface portion (29b), cleaning thereof becomes easier.

In the embodiment constructed as described above, the fluta (30
By not providing a part to prevent debris from flying upward in sQ+j in ), it is possible to eliminate the tendency of bu) below L of filter 〈3o〉 to prevent misuse.
The horizontal shifting operation of the filter (3o) shown in the figure can be easily performed.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and for example, a part to prevent debris from flying out may be formed at the upper end of the inner circumference of the filter (3o). Also, the relationship between the winding direction of the filter (3o) and the rotation direction of the separation * (29) may be reversed.Furthermore, the filter (3o) is configured so that it is in the most contracted state when the sword is not applied. Also, 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 figure.

In this case of hollow formation, the spiral body (30A) can be formed by extrusion. Also, the gap (69) (7g) (
Although it is preferable that the projections <81> and <82) for maintaining the distance shown in 80) are present, juice production is possible even without them.

(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 the liquid AE passage gap widened, making it easy to clean the filter and making sure that the filter is always clean. Can be kept clean. Further, the filter holding means prevents the liquid outflow gap from expanding rapidly, and prevents a large amount of waste from being mixed into the liquid.
