a and a ring body 1c for coupling with the cylindrical portion 1b.

Each part will be explained in detail below. Referring to FIGS. 2 and 3, the platform 1a is made of synthetic resin and consists of a horizontal portion 24 and a cylindrical support portion 25 projecting downward from the horizontal portion 24, and the lower inner periphery of the support portion 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 cylindrical shape with an open top and a bottom as shown in FIG. It serves as a low stage section 28 for a reservoir. A cylindrical fitting part 29 is formed in the center of the high step part 27, into which the support part 25 of the platform part 1a is fitted. Referring to FIG. 4, 30... is an engagement groove formed on the upper inner circumference of the fitting part 29, into which a protrusion (not shown) of the base part 1a is fitted to connect the base part 1a and the cylindrical part 1b. Acts as a rotation stopper.

The cylindrical portion 1b is held between the horizontal portion 24 by a ring body 1c that is fitted onto the outer periphery of the support portion 25 and bayonet-engaged therewith.

Referring to FIGS. 3 and 4, 30 is the filter 2.
The inner peripheral surface of the cylindrical portion 1b to which the cylindrical portion 2 is attached has a tapered shape with a larger diameter at the top so that the separated liquid can easily rise, and is also flat and has no rib-like protrusions. , four engagement grooves (first engagement portions) 31 are formed at the upper end. Each of the engaging grooves 31 has a vertical portion 31a whose upper end is open to the outside, through which engaging protrusions (second engaging portions) 32 described later of the filter 22 can be inserted vertically, and a separating tube formed at the bottom of the vertical portion 31a. Engagement protrusion 3 extending in the direction of rotation
2 consists of a horizontal portion 31b that is movable in the horizontal direction, and the upper wall 33 of the horizontal portion 31b has a horizontal surface 33a that is substantially horizontal on the vertical portion side and an inclined surface 33b that slopes downward on the opposite vertical portion side. is forming.

Reference numeral 34 denotes a fluid balancer formed in a substantially L-shape across the side and bottom surfaces of the cylindrical portion 1b.The side surface of the cylindrical portion 1b is made into a double wall with a bottom opening, and this bottom opening is closed with a ring-shaped bottom cover 35. A sealed space is formed, and an appropriate number of longitudinal resistance plates 36 are integrally provided in this space projecting from the outer wall side, and an appropriate amount of balancer liquid 37 is sealed in this space.

Next, the structure 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. On the surface constituting the liquid flow gap 38, there is a space-maintaining material on the lower surface of the spiral body 22A over almost the entire width in the radial direction so that the gap between each stage does not become narrower than a certain value (for example, 0.4 mm) when the filter 22 is pressed. Protrusions 39 are formed at equal intervals in the longitudinal direction of the gap.

As shown in FIG. 6, at the lowest stage of the filter 22, the terminal end 40 is detachable, and the abutting surfaces 41 and 42 are formed into inclined surfaces, and a hook-shaped protrusion is formed to maintain this engagement. 43 is formed. Reference numeral 44 denotes 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 45 becomes a flat surface with no step by changing the height dimension of the cross section. This prevents the outflow of waste by preventing the formation of gaps. To change the height of the bottom section above, you can create a spiral body with the same cross-sectional shape, glue a ring-shaped body to the bottom surface for height adjustment, or change the cross-sectional shape with a mold. However, in this embodiment, the latter is adopted.

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. Accordingly, the vertical interval of the upper terminal end 38a of the liquid flow gap 38 is formed wider than other parts, as shown in FIG. 8, to facilitate cleaning of this part. An annular flange 45 for retaining scum is integrally provided on the inner periphery of the uppermost stage. Further, a pair of bearing parts 46, 47 are formed on the top surface of the uppermost stage as shown in FIG. 9, and shaft holes 46a, 47a of the bearing parts 46, 47
A substantially semicircular synthetic resin handle 50 is rotatably provided with shafts 48 and 49 that are fitted in and rotatably supported and project inward at both ends.

Furthermore, a handle 5 is provided approximately at the center of the upper surface of the bearing portions 46 and 47.
Ribs 51 and 52 are formed to restrict the rotation of 0 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 correcting part 53 having substantially the same shape as the handle 50 is integrally formed on the uppermost side opposite to the inverted handle position. 54 is the top end face 5
This is a projecting wall that is erected at the inner peripheral end of the uppermost stage on the side of the handle in the inverted position to prevent debris from entering the gap between the handle 50 in the inverted position and the handle 50 in the inverted position.

Between each stage of the filter 22, projections 56a are formed from the upper surface of the lower stage, and grooves 57a in which the projections 56a fit are formed in the upper stage in a straight line in the vertical direction. A group of protrusions 56b and grooves 57b having the same shape as the group 57a are also formed at symmetrical positions with an interval of 180°. These protrusions 56a, 56b... and grooves 57
a, 57b, . . . constitute a blocking means for blocking the filter 22 from sliding in the rotational direction between stages. The grooves 57a, 57b... are cut out in the radial direction, and the protrusions 56a, 56b... are removable in the radial direction.
There are large R parts 58, 58 at the left and right corners of a and 56b.
is formed into a substantially semicircular shape with a small flat portion 59 at the top. These protrusions 56a, 56
The corner portions of the grooves 57a and 57b are also formed in a substantially semicircular shape in accordance with the shape of b.

The engagement protrusions 32 are provided on the outer periphery of the uppermost stage of the filter 22 and project horizontally outward at 90 degrees from each other, and are engaged with the engagement grooves 31 formed on the inner periphery of the upper end of the centrifugal separation cylinder 1. By cutting the material, the scraps get stuck between the stages of the filter 22 and the filter 2
This serves as a filter holding means that prevents the filter 22 from expanding in the vertical direction and also prevents the filter 22 from popping out.

An inclined surface 33a is formed in the engagement groove 31, and when the centrifugal separation tube 1 is started, the engagement protrusion 32 is guided downward by the inertia of the filter 22, and the filter 22 is moved into the centrifugation tube 1. It is pressed in the direction of tightening.

A notch 60 is formed at the upper end of the vertical portion 31a of the groove 31, and the handle 50 is widely exposed vertically through the notch 60, making it easy to place a finger on the handle 50 when raising it.

Reference numeral 62 denotes a fan-shaped regulating piece integrally formed at one end of the handle 50. With the engaging protrusion 32 engaged with the engaging groove 31, the handle 50 is folded down and the regulating piece 62 engages with the notch 60. By doing so, when the drive is stopped, etc.
The filter 22 is prevented from rotating in the disengagement direction of the engagement protrusion 32 due to inertia, and the filter 22
It is designed to prevent it from coming off. The regulating piece 62 is in a state where the handle 50 is rotated to the inverted position (first
(see Figure 1) and the first vertical plane 63 and the handle rotation center O
A circular arc surface 64 formed by drawing an arc upward from the bottom of the first vertical surface 63 with a radius R around , and a second vertical surface 65 with a small width formed at the upper end of the circular arc surface 64.
It has In this way, is the distance h ₁ from the center O to the second vertical surface 65 equal to the longest distance R from the center O to the peripheral edge of θ ₁ between the horizontal line y passing through the center O of the regulating piece 62 and the first vertical surface 63? By forming it long, when the operating state shown in FIG. 16A changes to the stopped state shown in FIG. 15, the handle 50 can be erected without rotating the filter 22 in the counter-X direction. The shape of the regulating piece 62 is not limited to a fan shape. Also, the horizontal line y and the first vertical plane 6
Although there is no regulating piece 62 of θ ₂ between the other side and 3,
If it exists, the distance h ₂ from the horizontal line y is made equal to or smaller than h ₁ . The first vertical surface 63 is located at the separation cylinder 1 in a state where the regulating piece 62 does not fit into the groove 31.
Functions as a support surface that comes into contact with the upper end surface 61 and supports the handle 50 in a vertically standing state (see FIG. 13),
The second vertical surface 65 is formed by the regulating piece 62 when the handle 50 is in the inverted position.
When the protrusion 32 is fitted into the engagement groove 31 (see FIG. 15), it comes into contact with the wall 74 of the vertical part 31a, and the protrusion 32 and the horizontal part 31b are disengaged from each other, that is, in the direction of rotation of the separation tube X. Functions as a rotation stopper for the filter.

Since the groove in which the regulation piece 62 engages uses the vertical portion 31a of the groove 31 in which the engagement protrusion 32 engages, the handle 50 is installed near the protrusion 32 in order to make this possible. Opening width l1 of portion 31a
is formed to be shorter than the distance l2 between one end 32a of the engaging protrusion 32 and the second vertical surface 65 when the handle is in the inverted position shown in FIG. Even if the groove 31 is applied, the protrusion 32 engages with the horizontal portion 31b of the groove 31 and is prevented from coming off in the upward direction.

Further, the opening width _l1 is formed to be approximately equal to or shorter than the distance _l3 between the one end 32a and the first vertical surface 63, so that when the handle 50 is folded down, the protrusion 32 and the regulating piece 62 form a groove. 31 so as not to fit into the upper end opening.

66, as shown in FIG.
A protrusion formed on the bottom surface of the separation tube 1 to ensure smooth rotation of the filter 22 when the separation tube 1 is activated is a protrusion that is elongated in the circumferential direction or has a spherical lower end to ensure a gap between the inner bottom surface of the separation tube 1 and the bottom surface of the separation tube 1. It is desirable to reduce the sliding resistance of 68... is filter 22
The inner circumferential surface 30 of the separating cylinder 1 is formed on the outer periphery of each stage.
A liquid flow gap 69 is formed between the two.

The filter 22, except for the handle 50, is integrally molded with resin using a mold. During molding, the filter 22 is molded with a relatively large liquid flow gap 38, and after being removed from the mold, it is thermally modified to reduce the gap. 38 is made narrower, and when the filter 22 is placed on a table as shown in FIG. 8, the stages of the filter 22 are brought into contact due to their own weight, that is, the protrusions 39 are brought into contact with the opposing surface, and no debris is attached. As shown in FIG. 4, when the filter 22 is pulled up by the handle 50, the gap 38 widens and the projections 56a, 56b, . . . and the grooves 57a, 57b, . . . are disengaged from each other. Also, the same filter 2
2 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 widens the gap 38 in the left-right direction, and the upper and lower ends It has a spring characteristic that when you hold it and shift it in the rotational direction, the diameter changes, and when these forces are released, it returns to its original state.

Further, the outer diameter of the filter 22 is formed to be slightly smaller than the inner diameter (tips of the protrusions 68) of the cylindrical portion 1b, and the inner circumferential surface 70 is tapered so that the diameter increases downward as shown in FIG. With this structure, the rotation of the separation tube 1 allows the scum to be accumulated from below, and also 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 such that the upper and lower corners of the outer surface are notched as shown in FIG. The flat surface facilitates 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. and,
The container lid 18b is fixed in a closed state and pressed onto the main body case 2 by clamp devices 72, 72 which are rotatably attached to the main body case 2 as shown in FIG. Reference numeral 73 denotes a push rod that is inserted into the material input cylinder 71 and pushes the material.

Next, a device for preventing danger due to abnormal attachment of a filter will be explained.

The filter 22 is normally installed in the separating tube 1 as shown in FIG. The condition that the projection 56 is engaged with the mating groove 31 (see FIGS. 15 and 16)
A, 56b... and grooves 57a, 57b... are engaged, and the end portion 40 of the filter 22 is engaged, the container lid 1 is closed.
8b can be set correctly, and the clamp devices 72, 7
It is configured so that 2 can be set. That is, in an abnormally mounted state of the filter 22 that does not meet any of the above conditions, the filter 22 protrudes upward from the separation cylinder 1 compared to 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. Normal installation of 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 into the separation tube 1 from the lower end. As it is inserted, the protrusions 32 generally ride on the upper end of the separation tube 1, and the handle 5
0, the container lid 18b cannot be set correctly as shown in FIG. Next, when the filter 22 is rotated appropriately, the protrusions 32 meet the vertical portions 31a of the grooves 31 and fall into the vertical portions 31a (see FIG. 13). In this state, the handle 50 is held in an upright position by the first vertical surface 63, and it goes without saying that the container lid 18b cannot be set, and if the handle 50 is forcibly pushed down in this state, the container lid 18b will open as shown in FIG. 17B. Cannot be set correctly.

When the filter 22 is rotated a little further from the state shown in FIG. 13, the regulating piece 62 falls into the groove 31 a little (see FIG. 14). Of course, the height of the regulating piece 62 may be set in advance so that it does not fall down a little.

In this state, the engagement protrusion 32 is already prevented from coming off 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 6 of the regulating piece 62
5 and the wall 74 of the vertical portion 31a face each other, and when they come into contact with each other, the rotation of the filter 22 in the separation tube rotation direction X can be prevented.

2. Rotation of Separation Cylinder 1 and Generation of Youth With the filter normally installed, the container lid 18b is set as shown in FIG. 1, and the clamp devices 72 are rotated to set it as shown by solid lines. When the operation switch 17 is turned on, the separation tube 1 rotates in the X direction, but the filter 22 slides and rotates in the counter-X direction with respect to the separation tube 1 due to inertia. This rotation causes the protrusions 32 to move into the grooves 31.
The filter 22 is engaged with the inclined surface 33b of the filter 22, and the filter 22 is pressed downward, and an auto-clamping function is performed to maintain the gap 38 at a constant distance against the force that tends to expand the liquid flow gap 38 up and down.

Then, materials such as fruits and vegetables are introduced into the input tube 71 and pushed in using the push rod 73. The material is then grated by the grater blade 28, thrown outward in the horizontal direction, and attached 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 flows through the gaps 38 and 67 and reaches the inner circumference of the cylindrical portion 1b. reaching the flow gap 69
After moving upward through the separation cylinder 1, the liquid flows out of the separation cylinder 1 and is received in the container 18. 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. When the material is further cut, the cut material also accumulates in the upper half of the filter 22 and is blocked by the flange 45.

3 Removing the filter 22 After finishing the youth generation and turning off the switch 17,
Contrary to the start-up, the filter 22 rotates relatively in the separating tube rotation direction X due to inertia, and the second vertical surface 65 of the regulating piece 62 comes into contact with the wall 74, automatically returning to the state shown in FIG. 15. In this state, the protrusion 32 and groove 3
Since the filter 22 is vertically engaged with the horizontal portion 31a of the filter 22, the upper part of the filter 22 tends to pop out due to the scraps being bitten between the stages, but this popping out is prevented. In this state, after removing the container lid 18b, place your hand on the part exposed from the notch 60 of the handle 50, raise the handle 50, pull it up slightly, and then rotate it in the direction of rotation of the separation tube as shown in FIG. 32 and the horizontal portion 31b are disengaged. In this state, the filter 22 can be taken out from the separation cylinder 1 by pulling up the handle 50.

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 gaps between the stages of the filter 22 may remain in close contact or in close proximity. By shifting the filter 22 horizontally in the direction that connects the corresponding pair of protrusions 56a..., 56b..., stretching it up and down, and further shifting it in the rotational direction, the waste can be dropped downward while remaining cylindrical. I can do it. Also, gap 3
Fibers etc. remaining on the gap 8 can be easily washed away by washing with water while the gap 38 is widened.

In the configuration of the above embodiment, since the grooves 31 that the protrusions 32 engage with and the grooves that the regulation piece 62 engages with are shared, there is no need to provide a separate groove for engaging the regulation piece 62, and the groove The number can be reduced, the strength of the separation cylinder 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 regulator using a comb-like filter as disclosed in Japanese Utility Model Publication No. 59-36171. or,
The second engaging portion may be made separate from the filter and integrated later, as in Japanese Utility Model Publication No. 59-36171. Further, when a comb tooth-shaped filter is used, the filter holding means may be of any type as long as it prevents the filter from moving upward. That is, specifically, it is not necessary to provide the inclined surface 33b on the horizontal portion 31b of the groove 31.

Moreover, the shape of the groove 31 is as shown in FIG.
It is also possible to provide only the inclined surface 33b without providing the slope a. Further, in the above embodiment, the engagement between the groove 31 and the protrusion 32 prevents the separation tube from rotating in the rotational direction, and the engagement between the regulating piece 62 and the groove 31 prevents the separation tube from rotating in the rotational direction. However, by forming the horizontal portion 31b of the groove 31 in the opposite direction, the rotation preventing function may be performed in the opposite direction. In this case, the regulating piece 62 prevents rotation when the rotational speed increases.

The protrusions 32 of the filter 22 and the grooves 31 of the separation tube 1
The filter holding means by engagement with the separation tube 1 may be configured by providing a protrusion on the separation cylinder 1 side and the groove on the filter 22 side, or the filter holding means may be formed by an annular shape provided on the outer periphery of the upper end of the separation cylinder 1 and the upper end of the filter 22. It may also be formed between the engagement piece (not shown).

The regulating piece 62 provided at the base of the handle 50 is connected to the protrusion 32.
The separation tube is prevented from rotating in the rotating direction by engaging with the engagement groove 31. As shown in FIG. It may be engaged with the notch 60 formed in... or a separate notch 60A. In this embodiment as well, the handle 50 is lifted up when the regulating piece 62A is not inserted into the groove, so that the container lid 18b cannot be set correctly.

In addition, the flange 45 for stopping waste is attached to the filter 22.
Although it is provided integrally with the lid, a separate lid may be provided to prevent waste. In this case, the lid does not have the function of holding the filter or 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 state) as shown in FIG. You may do so.

(g) Effects According to the present invention configured as described above, it is possible to reliably prevent the filter from popping out, and it is also possible to easily know whether the restriction piece is not inserted when the container lid is attached, thereby improving safety. You can improve.
