Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Field of Application The present invention comprises a centrifugal separation cylinder which has a cutter on the inner bottom for cutting 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 is equipped with a cylindrical filter that separates waste material into liquid and waste, and stores the waste in a centrifugal separation tube.

(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 circulation slits, and waste particles adhere to and accumulate on the inner circumferential surface of the filter. 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 removed 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.

In order to solve this drawback, the applicant has commercialized and sold a juicer in which a cylindrical filter is constructed of a spiral body having a spiral liquid flow gap in which the interval between adjacent stages can be expanded.

In a juicer having such a configuration, a load is applied to the uppermost stage of the filter when the filter is taken out after producing juice, so if the strength is to be increased, it is necessary to increase the +111 degree in the vertical direction of the Lmost stage of the filter. This has the drawback of increasing the height of the filter and, by extension, the height of the product. Further, this spiral filter has the disadvantage that it is easily deformed in the radial direction due to its shape, and may be deformed by external pressure during manufacturing, use, and storage. When deformed, it becomes difficult to attach and detach from the separation cylinder, and this non-circularity causes an imbalance in the accumulation of debris, which causes vibrations.

(c) Problems to be Solved by the Invention In view of the above-mentioned drawbacks, the present invention aims to improve the strength of the upper end of the filter without increasing the height of the product, and to prevent deformation of the filter.

(d) Means for solving the problems The present invention solves the above problems by forming the upper end of the filter in a non-removable manner and integrally forming a continuous scum-stopping flange on the inner periphery of the upper end. It is something.

(E) Effect: The above means reduces deformation of the upper end of the filter during storage, and the integral formation of the flange improves the strength of the upper end.

Each part will be explained in detail below. Referring to Figure 2 and Section 3, the platform (1a) is made of synthetic resin and the horizontal part (24
) and a cylindrical support part (25) projecting downward from the support part (25), and the lower inner periphery of this support part (25) is removably engaged with the outer periphery of the low-speed connector (11).

The cutter (23) is attached to the horizontal portion 24) by caulking with screws or rivets, and forms grating blades (26) as cutting blades radially from the center.

The cylindrical portion (1b) is made of synthetic resin and has a bottomed cylindrical shape with an opening on the top surface as shown in FIG. The outer periphery is a low step part (28) for collecting waste, and the center part of the high step part (27) has a cylindrical fitting part (29) into which the support part (25) of the stand part (1a) fits. ). Referring to Figure 4, (3

The upper wall 33) of 1b) forms a substantially horizontal horizontal surface (33a) on the vertical portion side and a downwardly inclined inclined surface (33b) on the anti-vertical portion side.

(34) is a fluid balancer formed in an abbreviated shape over the side and bottom surfaces of the cylindrical portion (1b). ! (35) to form a sealed space, and within this space, an appropriate number of longitudinal resistance plates (36) are integrally provided protruding from the outer wall side, and a balancer liquid is placed inside this space. (
37) in an appropriate amount.

Next, the configuration of the spiral filter (22) will be explained.

This filter is composed of a multi-stage cylindrical spiral body (22A) made of synthetic resin, for example ABS resin, and a spiral liquid flow gap (3B) is formed between each stage.

A filter (22) is provided on the surface of this liquid flow gap (38).
For pressing, the gap between each step is a constant value (for example, 0.4 f
The spiral (22
A) spacing projections (39) are formed on the lower surface of the gap over substantially the entire width in the radial direction at equal intervals in the longitudinal direction of the gap.

As shown in Fig. 6, at the bottom of the filter (22), the terminal end (40) can be freely engaged and detached, and the abutting surface (41>(42>) is formed into an inclined surface and this engagement is maintained. A hook-shaped convex portion (43) is formed so as to appear.

(44) is a concave portion formed so that the convex portion (43) engages in the vertical direction, and this concave-convex engagement prevents the terminal end from being disengaged downward.

Further, the lowermost stage of the spiral filter (22) is configured so that the lower end surface (75) becomes a flat surface with no step by changing the height dimension of the cross section.
The outflow of waste is prevented by preventing a large gap from forming between the inner bottom surface and the inner bottom surface. To change the dimension of the height of the bottom cross-section mentioned above, on the helical body with the same cross-sectional shape,
This can be done by bonding a ring-shaped body for height adjustment to the lower surface or by changing the cross-sectional shape with a mold, but the latter is adopted in this embodiment.

Next, in the uppermost stage of the filter (22), the terminal end is not detachable as in the lowermost stage, but has an integral structure.

Along with this, the upper end portion (38a) of the liquid flow gap (38)
As shown in FIG. 8, the upper and lower intervals are made wider than other parts to facilitate cleaning of this part. A continuous annular flange for retaining scraps (45) is integrally provided on the inner periphery of the uppermost stage. Furthermore, a pair of bearing parts (46) and (47) are formed on the top surface of the uppermost stage as shown in FIG.
fi) (47) shaft hole (pivotal part) (46a) (47a)
A shaft that fits into the shaft and is rotatably supported (pivotal support > (48)
A roughly semicircular synthetic resin handle (50) with (49) projecting inward at both ends is rotatably provided.

The filter (22) is configured such that one pivot portion of the filter (22) engages only one pivot portion of the handle (50).
And the shape of the pivot part of the handle (50) is set, that is, for example, as in the embodiment, the diameter of the hole (47a)≧the diameter of the shaft (49)>
By setting the diameter of the hole (46a)≧the diameter of the shaft (48>), it is impossible to install the handle (50) in the left and right directions, and the tip of one shaft (49) is cut diagonally (49a). This facilitates the work of first fitting the shaft (48) into the shaft hole (46a) and then fitting the shaft (49) into the shaft hole (47a) as shown in FIG. In addition, a projection (48b) is provided at the tip of the shaft (48) (49).
) (49b) and recesses (46b) (47b) are formed in the inner bottom walls of the shaft holes (46a) (47a), respectively, and by engaging them, the handle (50) is prevented from shaking when installed. I've lost it.

Furthermore, lips (51) and (52) for regulating the rotational direction of the handle (50) in one direction are formed on the obliquely upper side of the bearing parts (46) and (47) facing the shafts (48) and (49>). Handle (50
) has notches (50
a) (50b) is formed. Therefore, the handle (50)
When the handle (50) is tilted away from the folded position, the upper parts of the notches (50a) and (50b) of the handle (50) are pushed against the rib (5) as shown in Fig. 13.
1) The handle (50) is prevented from rotating by coming into contact with (52). Without this blocking action, the weight balance of the filter (22) would be disrupted and abnormal vibrations would occur due to the handle (50) being tilted in the opposite direction, but the occurrence of such abnormal vibrations can be prevented by the above-mentioned blocking action.

In addition, in the above-mentioned blocking action, since the ribs (51) and (52) are formed to face the shafts (4g) and (49), a force that tries to force the handle (50) to fall in the opposite direction is applied. In this case, as shown in Fig. 18 (c), the force (F) is
It acts perpendicularly to 48) (49) and is applied to the entire shaft, causing the shafts (48) and (49) to come off,
There is no possibility of breakage, so the strength of the pivot portion of the handle can be improved. On the other hand, if the lips (51) and (52) are placed in positions that do not oppose the shafts (4g) and (49) as shown by the dashed lines in the same figure, the above-mentioned force acts obliquely to the shafts,
This may cause the shaft to come off or break from the base.

In order to maintain the left and right weight balance of the filter (22) when the handle (50) is in the inverted position, the handle (50) is approximately the same as the handle (50).
A balance correcting portion (53) of one shape is integrally built up on the uppermost side opposite to the inverted position of the handle. By forming this build-up in a substantially semicircular shape on the upper end of the filter (22), the filter can become extremely high in some areas, or No unnecessary wind is generated by the protrusion.

(54) is a vertical wall formed inside the handle (50) at the upper end of the filter (22) to be higher than the bottom surface of the handle (50) in the inverted position. Without this vertical wall (54), when producing juice, a lot of scum accumulates and starts to fly out beyond the flange (45).
Lifting the handle (5o) by digging into the bottom of the vertical wall (50), the weight balance of the filter (22) will be disrupted and vibration will occur, and the handle (50) will come into contact with the container lid (18b), causing damage. By forming 50, such inconvenience can be avoided.

Between each stage of the filter (22), a projection (56a) is provided from the upper surface of the lower stage, and this projection (56a) is located in the upper stage.
A recessed groove (57a) into which the projections (56a) and the recessed grooves (57a) are fitted is formed in a straight line in the vertical direction.
7a)...Group and protrusions of the same shape (56b)...
- and concave grooves (57b)... groups are also formed at point-symmetrical positions with 180° intervals. This protrusion (56a)
(56b)... and grooves (57a) (57b)...
constitutes a blocking means for preventing the filter (22) from sliding in the rotational direction between the stages. The grooves (57a) (57b)
)... are formed in a notch shape in the radial direction, and the protrusions (56a) (56b)... are removable in the radial direction, and the left and right sides of each protrusion (56a) (56b) are removable. A large radiused portion (58) (5g) is formed at the corner, and the shape is approximately semicircular with a small flat portion (59) at the top. The corners of the grooves (57a) (57b) are also formed into approximately semicircular shapes in accordance with the shapes of the protrusions (56a) (56b).

The engaging protrusions (32)...are arranged at 90 degrees each other on the outer periphery of the uppermost stage.
The engagement grooves (31) formed on the inner periphery of the upper end of the separation cylinder (1) work to reduce the vertical distance between the stages of the filter (22). A filter holding means for pressing the filter (22) against the inner bottom surface of the separation cylinder (1) from above so as to prevent expansion of the filter (22), and a means for preventing rotation of the filter (22) in a direction opposite to the rotation direction of the separation cylinder are constructed.

Regarding the filter holding means, the engaging protrusion (32)
... is formed so that its upper surface height is lower than the height of the horizontal surface (33a) of the groove (31) in the naturally contracted state of the filter (22) shown in FIG. 8, and higher than a part of the inclined surface (33b), The engaging protrusion (32) is inserted into the vertical part (31a) of the groove (31).
) and then rotate it, the protrusion (32) will align with the inclined surface (
33b). This slope engagement constitutes a filter holding means that presses down the filter (22) from above so as to prevent the gap between the stages from expanding, and when the separation tube (1) is activated, the filter (22)
2) constitutes a rotation preventing means for preventing rotation of the separation cylinder in the opposite direction of rotation due to inertia.

(62) is a fan-shaped regulating piece that is integrally formed on one end of the handle (50), when the handle (50) is rotated to the inverted position (the first
(see Figure 2) and the first vertical plane (63) and the handle rotation center (0
) and a circular arc surface (64) formed by drawing an arc upward from the bottom of the first vertical surface (63) with a radius R.
64) A second vertical surface (65) with a small width formed at the upper end
It has This first vertical surface (63) has a regulating piece <6
2〉 does not fit into the groove (31) and remove the separation tube (1).
It functions as a support surface that comes into contact with the upper end surface (61) and supports the handle 50) in a vertically upright state (see Fig. 15), and the second vertical surface (65) is regulated by the inverted position of the handle (50). piece (6
2) is fitted into the engagement groove (31) (see Figure 17)
The protrusion (3) comes into contact with the wall (74) of the vertical part (31a).
2) and the horizontal portion <31b), which functions as a rotation-stopping surface of the filter in the direction in which the separation tube rotation direction (X) is disengaged. In addition, the handle (50) is formed by forming the arcuate surface (64).
This makes it easier to raise and lower.

Since the groove in which the regulation piece (62> engages) uses the vertical part (31a) of the groove (31) in which the retaining protrusion (32) engages, the handle (50) is attached in order to make this possible. The position is near the protrusion (32), and the opening width (!) of the vertical portion (ata).
1) is the engagement protrusion (32) at the handle side position in Fig. 17.
The distance (
12), so that even if an upward force is applied to the filter (22) in the normally installed state of the filter shown in FIG. 17, the projection (32) will not engage with the horizontal portion (31b> of the groove (31) The structure is such that upward removal is prevented.

(66) ... is a protrusion formed on the bottom surface of the filter (22) to ensure a liquid flow gap (67) between the separation*(1) inner bottom surface and the bottom surface of the lowest stage of the filter (22) as shown in Fig. 14. In order to smoothly rotate the filter (22) when starting the separation cylinder (1), the shape is elongated in the circumferential direction, or the lower end is made spherical to reduce the sliding resistance between the separation cylinder (1) and the inner bottom surface. It is desirable that (68)... is a filter <22
) is formed on the outer periphery of each stage to separate the inner peripheral surface of the separation tube (1) (3
0) to form a liquid flow gap (69).

The filter (22), except for the handle (50), is integrally molded with resin using a mold, but during molding, the liquid flow gap (38) is
) is molded with a relatively large gap (38), and after being taken out from the mold, it is thermally modified to narrow the gap (38), and when placed on a table as shown in Figure 8, the filter becomes smaller than 22) due to its own weight. The filter (22) is configured so that the stages are in contact with each other, that is, the protrusions (39) are in contact with the opposing surface, and the filter (22) is held by the handle (50) as shown in Fig. 4 with no debris attached. When pulled out, the gap (38) expands and the projections (56a) (56
b)=- is configured to disengage from the grooves (57a), (57b), and so on. Further, the filter (22) expands when a stretching force is applied in the vertical direction, and when a force is applied in the horizontal direction, lateral displacement occurs between the stages, which also causes the gap (38) to expand in the horizontal direction. It has a spring characteristic that changes its diameter when it is held at its upper and lower ends and shifted in the direction of rotation, and returns to its original state when these forces are released.

Further, the outer diameter of the filter (22) is formed to be slightly smaller than the inner diameter of the cylindrical portion (lb) (the tip of the protrusion (68)), and the inner circumferential surface (70) faces downward as shown in FIG. By forming the tapered surface to have a large diameter, the separation tube (1)
By rotating the filter, debris is accumulated from below first, and the debris is easily removed from the filter in the downward direction.

In addition, the cross-sectional shape of each stage of the filter (22) is cut out at the upper and lower corners of the outer surface as shown in Fig. 3, which reduces the flow resistance of liquid flowing out from the gap (38) and The inner surface is made flat to facilitate the movement of debris. Note that the form of this notch is not limited to that shown in the drawings.

Next, referring to FIG. 1, the container lid (18b) has a material input tube (71) integrally provided vertically so as to face a portion off the center of the cutter (28). Then, the container lid (18b) is closed and pressed onto the main body case (2) by clamp devices (72) (72) rotatably attached to the main body case (2) as shown in Fig. 1. It is fixed in the state. (73) is a push rod that is inserted into the material input cylinder (71) and pushes the material.

Operation explanation> 1. Normally attached filter (22) When the handle (50) of the filter (22) is held in hand, the filter (22) will be in an extended state as shown in Fig. Insert into the separation tube (1). As it is inserted, the protrusion (32)... generally becomes separated from the separation tube (1).
The primary filter (22
) is rotated appropriately, the protrusion (32)... will become the groove (31).
) ... coincides with the vertical part (31a) of the vertical part (31a)
Feeling depressed (see Figure 15).

If the filter (22) is rotated a little further from the state shown in Fig. 15, the regulating piece (62) will fall into the groove (31) a little (
(See Figure 16).

In this state, the retaining protrusion (32) is already prevented from being pulled out upward by the horizontal portion (31b) of the groove 31). Then, when the handle (50) is folded down, the normal mounting state shown in FIG. 17 is realized, and the second vertical surface (65) and the vertical part (
The wall (74) of the filter (31a) faces the wall (74), and the contact between the two prevents the filter (22) from rotating in the rotation direction (X) of the separation cylinder.

2. Rotation of the separation cylinder (1) and juice production With the filter normally installed, set the container lid (18b) as shown in Figure 1, and rotate the clamping devices (72) as shown in the solid line. set.

When the operation switch (17) is turned on, the separation cylinder (1)
rotates in the (X) direction, but the filter (22) slides and rotates in the opposite (X) direction with respect to the separation cylinder (1) due to inertia. This rotation causes the protrusion (32)... to become the groove (31).
... engages with the inclined surface (33b) of the filter (22).
is pressed downward, and an auto-clamping function is performed to keep the gap (38) distance constant against the force that tries to expand the liquid flow gap (38) up and down.

Then, ingredients such as fruits and vegetables are put into the input cylinder (71) and pushed in with the push rod (73), and the ingredients are removed by the grater blade.
8), and is blown outward in the horizontal direction and adheres to the inner periphery of the filter (22). This adhered material to be cut descends along the tapered inner surface of the filter (22) and is separated into scraps and liquid, and the liquid is separated from the gap (
38) and (67), reaches the inner periphery of the cylinder part (1b), moves upward through the circulation gap (69), flows out of the separation cylinder (1), and enters the container (18). You can receive it. This liquid flows down from the outlet <20) and is received by the cup (5).

On the other hand, the waste is accumulated sequentially from the inner lower end of the filter (22). As more material is cut, the material to be cut also accumulates in the upper half of the filter (22) and flange (45).
It is stopped by.

36 Take out the filter (22) When juice generation is finished and the switch (17) is turned off, the filter (22) rotates relatively in the separation cylinder rotation direction (X) due to inertia, contrary to the start-up, and automatically returns to the state shown in Figure 17. to return to normal. In this state, after removing the container lid (18b), the handle (50)
After standing up and pulling up slightly, rotate the separation tube in the rotating direction as shown in Fig. 15 to disengage the protrusion (32) and the horizontal part (31b), and in this state, pull the handle (50) upward. By pulling up the filter (22) into the separation cylinder (1)
It can be taken out from.

4. Removal of debris This drawn out state is similar to that shown in Figure 4, but depending on the adhesive strength of the debris adhering to the inner periphery, the filter (22)
The gaps between the stages may be kept in close contact or close to each other, and the filter (22) is connected to the corresponding pair of protrusions (56a)...
(56b)...By shifting the group horizontally in the direction that connects the group, stretching it up and down, and further shifting it in the rotational direction, the waste can be dropped downward while remaining cylindrical. or,
Fibers and the like remaining in the gap (38) can be easily washed away by washing with water while the gap (38) is widened.

11. (G) Effects According to the present invention configured as described above, the strength of the upper end of the filter can be improved without increasing the height of the filter, and deformation of the upper end of the helical filter, which is easily deformed, can be prevented.
It has great effects such as being able to eliminate various defects caused by deformation.
