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). The chamber is closed at (35) to form a sealed space, and within this space, an appropriate number of vertical resistance plates (36) are integrally provided protruding from the outer wall side, and a balancer liquid (
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 (38) 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, 0.41
111) Spiral body (22A) so as not to become narrower than
The spacing protrusion (
39)... are formed 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) is removable, and the abutting surfaces (41) and (42) are formed into inclined surfaces 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.
A large gap is not formed between the inner bottom surface and the waste is prevented from flowing out. 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. An annular flange (45) for retaining scum is integrally provided on the inner periphery of the uppermost stage. Also, on the top surface of the top stage there is a pair of bearings (
46) (47) are formed, and this bearing part (46) (47) is formed.
) is inserted into the shaft holes (46a) (47a) of the shaft (48>(49)) and is rotatably supported. It is set up so that it can be moved freely.

In addition, a handle (5
0) are formed with ribs (51) and (52) that restrict rotation in one direction.

In order to maintain the left and right weight balance of the filter (22) when the handle (50) is in the inverted position, a balance correction part (53) having approximately the same shape as the handle (50) is integrally formed on the uppermost stage opposite to the inverted position. are doing. (54) is the top end face (55
) and the handle (50) in the reclined position to prevent debris from entering the gap between the handle (50) and the handle (50) in the inverted position.

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.
The recessed groove (57a) into which the projections (56a) and the recessed grooves (5
7a)...Protrusion (56b) with the same shape as this group...
- and concave grooves (57b)... groups are also formed at point-symmetrical positions with an interval of 180°. This protrusion (56g)
(56b)...= and groove (57a>(57b)...
constitutes a blocking means for preventing the filter (22) from sliding in the rotational direction between the stages. Said groove (57a) (57
b) ... is formed in a notch shape in the radial direction, and
The protrusions (56a), (56b), etc. can be freely engaged and disengaged in the radial direction, and large rounded portions (58) (58) are formed at the left and right corners of each protrusion (56a) (56b). It has a substantially semicircular shape with a 9-degree flat part (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 upper and lower intervals between the stages of the filter (22) work together with the engagement grooves (31) formed on the inner periphery of the upper end of the separation tube (1), and The filter (22) is placed in a
22) from above against the inner bottom surface of the separation cylinder (1), and a means for preventing the filter (22) from rotating in the same rotational direction as the ash content wL.

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> in FIG. 8) and higher than a part of the inclined surface (33b), The engaging protrusion (32) is connected to 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 separating tube (1) is activated, the filter (
22) constitutes a rotation preventing means for preventing rotation in the anti-separation cylinder rotation direction due to inertia.

A notch (60) is provided at the upper end of the vertical portion (31a) of the groove (31).
) is formed, and the handle (50) is widely exposed vertically from the notch (60), making it easy to put a guard finger on when raising the handle 50〉.

(62) is a layered regulation piece integrally formed on one end of the handle (50), which is used when the handle (50) is rotated to the inverted position (first
(see Figure 1) 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) second vertical surface (65) with a small width formed at the upper end;
It has In this way, the distance (hl) from the center (0) to the second vertical surface (65) is the center (0) of the regulating piece (62).
) between the horizontal 1m (y) and the first vertical plane (63) (
By forming the filter (22) to be equal to or longer than the longest distance (R) from the center (0) of
) The handle (50) can be erected without being rotated in the opposite (X) direction.

The shape of the regulating piece (62) is not limited to a flat shape.

Also, between the other horizontal line (y) and the first vertical plane (63) (
The regulating piece (62) of 02) does not exist, but if it does exist, the distance (h2) from the horizontal line (y) is set to be equal to or smaller than hl. While the regulating piece (62) does not fit into the groove (31), it comes into contact with the upper end surface (61) of the minute cylinder (1) to support the handle (50) in a vertically standing state (see Figure 13). Functioning as a support surface, the second vertical surface (65) supports the handle (
50) in the tilted position and the regulating piece (62) is fitted into the engagement groove (31) (see Fig. 15), the vertical part (31a) wall (
74) and functions as a rotation-stopping surface for the filter in the direction in which the projection (32) and the horizontal portion (31b) are disengaged, that is, in the separation tube rotation direction (X).

Since the groove in which the regulation piece (62) engages uses the vertical portion (aXa) of the groove (31) in which the engagement 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 (1
1) is the engagement protrusion (32) at the handle side position in Fig. 15.
It is formed to be shorter than the distance (12) between one end (32g) and the second vertical surface (65g), so that even if an upward force is applied to the filter (22) when the filter (151) is normally installed, The protrusion (32) is the horizontal part (31b) of the groove (31)
It is configured so that it is engaged with and prevented from being pulled out in the upward direction.

Further, the opening width (11) is formed to be approximately equal to or shorter than the distance (I13) between the one end (32a) and the first vertical surface (63), and the protrusion is formed when the handle (50) is folded down. (3
2) and the regulating piece (62) are configured so that they do not fit into the upper end opening of the groove (31).

(66)... is the separation cylinder (1) as shown in No. 12'rEJ.
A protrusion formed on the bottom surface of the bottom surface of the filter (22) to ensure a liquid flow gap (67) between the inner bottom surface and the bottom surface of the lowest stage of the filter (22) enables smooth rotation of the filter (22) when the separation tube (1) is started. It is preferable to make it elongated in the circumferential direction or to make the lower end spherical to reduce the sliding resistance between the separation tube (1) and the inner bottom surface.
A liquid flow gap (69) is formed between the projections formed on the outermost periphery of each of the separation cylinders (1) and the inner peripheral surface (30) of the separation cylinder (1).

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 removed from the mold, thermal correction is performed to narrow the gap (38), and when placed on a table as shown in Figure 8, the filter (22) The filter (22) is configured so that the stages are in contact and 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 up, the gap (38) expands and the protrusions (56a) (56
b)... and the grooves (57a), (57b) -... are configured to disengage from each other. Also, the same filter 22)
When a stretching force is applied in the vertical direction, it expands, and when a force is applied in the horizontal direction, lateral displacement occurs between the stages, which also increases the distance between the gaps (38) in the left-right direction, and also causes the upper and lower ends to It has a spring characteristic in which the diameter changes when you hold it and shift it in the rotational direction, and it 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 (the tips of the protrusions (68)) of the cylindrical portion (1b), and the inner peripheral surface (70) is formed downward as shown in FIG. By forming the tapered surface so that the diameter becomes larger in the direction
) causes the scum to accumulate from below first and facilitates the removal of the scum 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 drawing.

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 case (2) by a clamp device (72) (72>) rotatably attached to the main case (2) as shown in Fig. 1. (73) is an insertion rod that is inserted into the material input cylinder (71) to push the material.

Next, a description will be given of the danger assistant device due to the abnormal attachment of the filter.

The filter (22) is in the normally installed state in the separation cylinder (1) shown in FIG. 15, that is, in this embodiment, the engaging protrusion (32)...

The container lid (18b) can only be correctly set when the conditions that the . (72) The configuration is such that (72) can be set. In other words, a filter (22
), the filter (22) is attached to the separation tube (1).
) protrudes upward from the normal state, and the container lid (18b)
cannot be set.

Further, the clamp devices (72) (72) are provided with an electromechanical safety switch device (not shown) which does not turn on and prevent the motor from rotating unless the clamp devices (72) (72) are set.

<Operation Description> 1. Normally attached filter (22) When the handle (50) of the filter (22) is held by hand, the filter (22) will be in an extended state as shown in Fig. 4, and the filter (22) will be inserted from the bottom end. Insert into separation #(1). As it is inserted, the protrusion (32)... generally becomes separated from the separation tube (1).
), and even if the handle (50) is tilted down, the container lid (18b) cannot be set correctly as shown in Figure 18.6 Next, when the filter (22) is rotated appropriately, the protrusion (32)... · is the vertical part (31a) of the groove (31)...
) and falls into the vertical part (31a) (see Figure 13), in this state the handle (50) is in the first vertical plane (63).
It is held in an upright position by the container lid (18b).
), and in this state, I was forced to remove the handle (5 cents).
0) e When folded down, the container lid (18b) will open as shown in Figure 17 (b).
If the filter (22) is rotated a further 9 degrees from the state shown in Figure 13, the regulating piece (62) will fall a little into * (31) (see Figure 14), but of course be careful not to drop it a little. It is also possible to set the height of the regulating piece (62) in advance.

In this state, the engagement 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. 15 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.

Then, 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. Due to this rotation, the protrusions (32)...
... 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, materials such as fruits and vegetables are put into the input tube (71) and pushed in with the push rod (73), and the materials are then
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 circumferential 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 separating cylinder 1), and enters the container (18>). This liquid flows down from the outlet (20) and is received by the cup (5).1 Meanwhile, the waste is accumulated sequentially from the inner lower end of the filter (22).Moreover, the material is cut. , the material to be cut is filtered (2
2) It is also accumulated in the improvement half and is blocked by the flange (45).

3. Take out the filter (22) When juice production is finished and the switch (17) is turned off, the filter (22> rotates in the direction of rotation of the separation tube (X) due to inertia, contrary to the start-up, and the regulating piece (62) Second vertical plane (65
) comes into contact with the wall (c) and automatically returns to the state shown in Fig. 15. In this state, the horizontal part of the protrusion (32) and groove (31) (
Since the filter (31a) is engaged in the vertical direction, the filter (
22) is about to pop out due to the scraps biting into the space between the steps, but this popping out is prevented.

In this state, after removing the container lid (18b), the handle (
Put your hand on the part exposed from the notch (60) of 50), raise the handle (50), and after pulling up the
As shown in Figure 3, rotate the separation cylinder in the rotating direction to disengage the protrusion (32) and the horizontal part (31b), and in this state,
By pulling up the handle (50), the filter (22
) can be taken out from the separation cylinder (1).

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)... horizontally shift in the direction that connects the groups,
By stretching it up and down and then shifting it in the direction of rotation, it is possible to drop the debris downward while keeping it cylindrical. In addition, fibers and the like remaining in the gap (38) can be easily washed away by washing with water while the gap is expanded (<38).

In the configuration of the above embodiment, since the grooves (31)... in which the protrusions (32)... engage and the grooves in which the regulation piece (62) engages are shared, the regulation piece (62) is protected. There is no need to provide a separate groove for the combination, the number of grooves can be reduced, and the separation tube (
1) can be improved, and the separation cylinder (1) can be easily cleaned.

Next, another embodiment of the present invention will be described.

Although a helical filter is used in the above embodiment, the present invention can also be applied to a juicer using a comb-shaped filter such as that disclosed in Japanese Utility Model Publication No. 59-36171. Alternatively, the second engaging portion may be separated from the filter and later integrated into the filter, as in Japanese Utility Model Publication No. 59-36171. In addition, when a comb-shaped filter is used, the filter holding means may be of any type as long as it prevents the filter from moving upward. Specifically, the horizontal part (31b) of the groove (31) is ) is not necessary.

Moreover, the shape of the groove (31) is as shown in FIG.
) may be omitted and only the inclined surface (33b) may be provided.

Further, in the above embodiment, the engagement between the groove (31) and the protrusion (32) prevents the separation tube from rotating in the rotating direction, and the regulating piece (62)
The horizontal part (31b of the groove (31)
) may be formed in the opposite direction to perform the rotation prevention function in the opposite direction. In this case, the regulating piece (62) serves to prevent rotation when the rotational speed increases.

Protrusion (32) of filter (22)... and separation tube (1)
The filter holding means by engagement with the grooves (31) may be configured by providing a protrusion on the separation cylinder (1) side and a groove on the filter (22) side, or the filter holding means may be configured by providing a protrusion on the separation cylinder (1) side and a groove on the filter (22) side.

) may be rotated to engage the notch (60A), or as shown in Fig. 22, a cam-shaped regulating piece (62C) that rotates around the shaft (70) may be provided to engage the notch (6OA). Alternatively, the regulating piece may be provided on the separation cylinder (1) side and the notch may be provided on the filter (22) side.

Further, a handle (50) is provided at the upper end of the filter (22) to facilitate attachment and detachment, but this is not always necessary.

In addition, the flange (45) for retaining waste is attached to the filter (22).
Although it is provided integrally with the filter, a separate lid may be provided to prevent waste. In this case, the lid does not have the function of holding the filter and preventing rotation.

Furthermore, the filter (22) is configured so that the stages are in contact with each other when it is placed on the installation surface (naturally placed) as shown in FIG.
It may be configured such that the stages are brought into contact by applying force from above.

(g) Effects According to the present invention configured as described above, there are great effects such as being able to reliably prevent the filter from popping out due to changes in the rotational speed of the motor.
