Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention comprises a centrifugal separation cylinder which has a cutter for cutting material on the inner bottom and is rotated by a motor, and a centrifugal separation cylinder which is attached to the inner periphery of the separation cylinder and which cuts the material. This invention relates to a juicer that is equipped with a cylindrical filter that separates the collected material into waste and liquid, and that collects 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 outflow slits, and debris adheres to and accumulates on the inner peripheral 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 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 debris has been the main reason for hesitation in using Jusa itself.

(c) Object of the Invention In view of the above-mentioned drawbacks, it is an object of the present invention to provide a juicer with improved ease of use and a good reduction ratio by making it easier to remove debris.

(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 for cutting the material and is rotationally driven by a motor, and a centrifugal separation tube that is detachably attached to the inner circumference of the separation tube and holds the cut material. A juicer is provided with a cylindrical filter that separates waste and liquid, and the waste is stored in the centrifugal separation cylinder, and the cylindrical filter is provided with a spiral first liquid flow gap whose interval can be expanded. In addition, the lower end surface of the helical filter is formed to be substantially flat, and a second liquid flow gap is provided between the helical filter and the inner bottom surface of the separation tube.

Due to this configuration, debris adheres to and accumulates on the inner circumference 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 first
Since the intervals between the liquid flow gaps vary greatly, the scum can easily be removed from the filter, and if the filter is washed with the gaps widened, the scum stuck in the gaps can be easily washed away. Furthermore, since a second liquid flow gap is also formed between the lower end surface of the filter and the inner bottom surface of the separation cylinder, the amount of reduction in use is increased.

Further, a plurality of temporary fixing protrusions 35 and a plurality of engagement protrusions 36 are formed on the outer periphery of the lower part of the support portion 32, and rotation preventing protrusions 37 are formed on the outer periphery of the upper end. 31b is the horizontal part 3
This is a protrusion extending from the central lower surface of connector 1 to near the upper surface of connector 10 to prevent the connector from rising.

The cutter 38 is attached to the horizontal part 31 by screws or rivets, and forms cutting blades 39 radially from the center as cutting blades, and also performs re-cutting to finely re-cut the remaining material by cutting back on the periphery. A plurality of blades 40 are formed,
The outer edge is partially extended outward to form a regulating plate 41 to be described later.
A plurality of extending portions 42 for peripheral edge contact are formed.
43... is a surrounding protrusion integrally provided from the horizontal part 31 at the same height as or higher than the height of the extension part 42 so as to surround the extension part 42... on three sides, and the edge of the extension part 42... The periphery of the input tube 44, which will be described later, is protected from being cut. 45... are material retaining ribs that are discretely provided around the cutter 38 and protrude integrally from the horizontal part 31 higher than the upper surface of the grating blade 39, and because the interval between the recutting blades 40... is large, the ribs are larger than this interval. The material tends to fly out, but this flying out is suppressed.

The cylindrical portion 29b is made of synthetic resin and has a cylindrical shape with an open top and a bottom as shown in FIGS.
The high step part 46 whose outer periphery is a low step part 52 for collecting waste has a tapered shape that expands the outer periphery 46a downward in order to facilitate the separation of the waste accumulated on the low step part 52. At the same time, a cylindrical fitting part 47 into which the support part 32 of the stand part 29a fits is formed in the center part, and the outer periphery of the upper end part 32a of the support part 32 is connected to the upper inner peripheral surface 47a of the fitting part 47.
The lower surface 31a of the outer periphery of the horizontal portion 31
is brought into surface contact with the upper surface 46a of the high step portion 46. With this two-face contact between the horizontal surface and the vertical surface, the base part 2
This reliably prevents wobbling between the cylindrical portion 9a and the cylindrical portion 29b, and improves the support strength. 48... is an engagement groove formed on the upper inner circumference of the fitting part 47, into which the protrusion 37... of the base part 29a is fitted and the base part 29a is inserted.
This acts to prevent the rotation of the cylindrical portion 29b. 49...
are locking claws discretely formed on the inner periphery of the lower end of the fitting portion 47;
When fitted onto the holder 7, it is elastically deformed and engages over the protrusions 35, thereby temporarily fixing the two 29a and 29b.

In this temporarily fixed state, the ring body 29c is fitted onto the outer periphery of the support portion 32 of the base portion 29a, and the cylindrical portion 29b is held between the ring body 29c and the horizontal portion 31 to ensure the connection of both 29a and 29b. There is.

With reference to FIGS. 9 and 10, the ring body 29c
Forms protrusions 51 having slopes 50 that bayonetly engage with the protrusions 36 of the base portion 29a, and also forms a receiving surface 53 for receiving the lower end of the fitting portion 47. Note that the support portion 32 and the ring body 29c may be connected by a threaded groove (not shown) instead of bayonet engagement.

In FIG. 4, a step portion 54 is formed on the outer peripheral edge of the high step portion 46.
The outer peripheral edge of the horizontal part 31 of the platform part 29a is made to protrude downward to correspond to the above, and this protruding part 55 is fitted into the step part 54, thereby making it difficult for debris to adhere to the gap between the horizontal part 31 and the high step part 46. It has a structure.

56 is a cylindrical portion 29b to which the filter 30 is attached.
The inner peripheral surface of the tube has a tapered shape with a larger diameter at the top so that the separated liquid can easily rise.
A plurality of vertical protrusions 57a at appropriate intervals,
57b... are formed, and a liquid flow gap 58 is provided between the filter 30 and the outer peripheral surface of the filter 30. The above-mentioned protrusions 57a, 57b, etc. engage with protrusions 83, which are provided on the outer surface of the filter 30, which will be described later, at an angle of about 180 degrees from each other in the direction of rotation, thereby preventing relative rotation of the filter 30. Moreover, the protrusion 57b is the protrusion 5
A support protrusion 57c has a wider width than 7a and extends to a large diameter portion 60 formed at the upper end inside the cylindrical portion 29b, and abuts on the outer surface of the upper end of the filter 30.
are connected to the top end. On the inner periphery of the large-diameter portion 60, locking protrusions 62 for a lid 61, which will be described later, are integrally provided to protrude inward.

Reference numeral 63 designates a fluid balancer formed in a substantially L-shape over the side and bottom surfaces of the cylindrical portion 29b;
The sides are formed into double walls 64 and 65 with a bottom opening, and this bottom opening is closed with a ring-shaped bottom cover 66 to form a sealed space, and the outer wall 6 is inserted into this space.
A suitable number of vertical resistance plates 67 are integrally provided projecting from the 5 side, and a suitable 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 an inner end of the lower surface of the bottom step portion 52, and is sealed by high frequency welding, and this concave-convex fit improves sealing performance. P1 and P2 are metal rings used for high frequency welding. The outer wall 65 has a tapered shape with a diameter increasing at the bottom to make the lower part of the sealed space wider than the upper part, thereby concentrating the liquid 68 downward and preventing the liquid from rising upward.

As shown in FIGS. 11 to 13, the spiral filter 30 is composed of a multi-stage cylindrical spiral body 30A made of synthetic resin, for example, ABS resin.
A spiral liquid flow gap 69 is formed between each stage and has a spring property. This spiral 30A
When no force is applied in the direction of contraction in the cylinder axis direction (natural extension state), the upper gap 69 is in a slightly expanded state as shown in Fig. 11, and the lower gap 69 is in a non-expanded state due to its own weight. It is molded using a mold, and when the lid 61 is closed, all the gaps 69 are at their minimum, and when a force is applied in the direction of extension of the cylinder axis from the state shown in the figure, the gaps 69 in the figure 12 become the same. expands, and when this force is released, it returns to the state shown in FIG. 11 by its own spring force. When a force is applied in the horizontal direction, lateral displacement occurs between the steps, which also causes the gap 69 to expand in the left-right direction, and when the upper and lower ends are held and shifted in the rotational direction, the diameter changes. have. The length of this spiral body 30A in the cylindrical axial direction is the depth l1 of the cylindrical portion 29b when the lid 61 is closed.
It is formed substantially equal to l1 even in the natural elongated state shown in FIG. 11.

Further, the final stage 30a, 3 of the spiral filter 30
0a is configured such that the end surfaces 70, 70 are flat surfaces with no steps, so that the inner surface of the lid 61 and the cylindrical portion 2 are
The outflow of waste is prevented by preventing a large gap from being formed between the inner bottom surface and the inner bottom surface of 9b. To change the height dimensions of the cross-sections of the final stages 30a and 30a mentioned above, ring-shaped bodies for height adjustment may be glued to the top and bottom surfaces of the helical body with the same cross-sectional shape, or This is possible by changing the
In this embodiment, the latter is adopted. The end portions 71, 71 are made sufficiently thick in the cylinder axis direction to ensure the strength of the end portions, and the end portions 71, 71 are provided with a protrusion 72a for preventing slipping off in the vertical direction and a protrusion 72b for preventing slipping off in the rotational direction. are provided, and the end portions 71, 7
There are protrusions 72a, 72 on the mating surface corresponding to 1.
Grooves 73a and 73b are formed in which the grooves 73a and 73b are fitted and engaged, respectively. This first engagement between the protrusion 72a and the groove 73a prevents the filter 30 from being overextended due to force acting on the final stage 30a, 30a when the filter 30 with debris attached thereto is pulled up. The second engagement between the groove 72b and the groove 73b causes the diameter of the filter to expand when the filter 30 rotates, so that the first engagement does not come off. The above first and second engagements are performed by the filter 3.
Since the cleaning is performed on the outer circumferential side of the 0, there is less adhesion of debris and cleaning is easy.

Further, the outer diameter of the spiral body 30A is formed to be slightly smaller than the inner diameter of the cylindrical portion 29b (the tips of the protrusions 57a, 57b...), and the outer surface 74 is smaller than the inner diameter of the cylindrical portion 29b (tips of the protrusions 57a, 57b...).
... and the inner circumferential surface 75 is formed into tapered surfaces 75a, 75a so that the diameter increases symmetrically upward and downward from the midpoint 0 as shown in FIG. The rotation of the filter causes the scum to accumulate from below, and also facilitates the removal of the scum from the filter in the downward direction. In the embodiment, the filter 30 is formed with a larger diameter toward the top and bottom in order to eliminate the vertical directionality.
If it has directionality, it may be formed into a tapered surface whose diameter increases from top to bottom.

Further, the cross-sectional shape of each step of the spiral body 30A is as shown in FIG.
a, 76a, thereby creating a gap 69
The flow resistance of the flowing liquid is further reduced, and the inner surface 76b of each stage is made 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, and the inner surface 76b may be curved as long as it is not necessary to improve the mobility of the debris.

Furthermore, since the spiral body 30A requires a spring force to prevent it from stretching too much when the filter is taken out, it requires a somewhat wide cross-sectional area, but in this embodiment, the vertical width F is longer than the horizontal width E of the cross-section. . By setting F>E, the filter 30
When the internal space volume is constant, the filter 30
This prevents the outer diameter from increasing. However, if there is no restriction on the outer diameter, it may be set to F≦E. Although the facing surfaces of each stage are formed as flat surfaces 77a, 77b, etc. so that the cylindrical shape is not destroyed even if the filter 30 is displaced laterally, it is also possible to form them as concave or convex surfaces that fit into each other. good.

Further, referring to FIG. 4, the spiral body 30A forms a liquid flow gap 69 between each stage, and a liquid flow gap 79 between a protrusion 87 on the bottom surface of the lid 61 and a top surface of the low step part 52 of the cylindrical part 29b. , 80. In the lid closed state shown in the same figure, this gap is formed by the spiral 3
Spacing projections 81 are formed on the lower surface of A at equal intervals in the longitudinal direction of the gap 69 over substantially the entire width in the radial direction of the flat surface 77b.
0, similar spacing-maintaining protrusions 82 are formed at the same height as the protrusions 81 on the upper and lower end surfaces of the spiral body 30A. These protrusions 81
. . , 82 . . . , the ease of liquid outflow is approximately equal throughout the entire vertical direction of the filter. Note that the latter projections 82 may be provided on the lid 61 and the cylindrical portion 29b side instead of being provided on the spiral body 30A, and the former projections 81 may be provided on the upper surface side of the spiral body 30A. Further, the protrusions 81..., 82... may be knurled protrusions.

Further, the winding direction of the spiral body 30A is set so that the diameter increases. For example, when the rotation direction of the separation cylinder 29 is counterclockwise x when viewed from above, the winding direction from the top to the bottom is set to the direction in which the diameter increases. It is shaped so that it faces clockwise when viewed.

As shown in FIGS. 4 and 14 to 17, the lid 61 is fitted and locked into the large-diameter upper end portion 60 of the cylindrical portion 29b to prevent the filter 30 from coming off and to create a lid area on the inner periphery of the filter 30. It is configured to have a function of preventing the discarded waste from flying out. Reference numeral 61a denotes a cylindrical vertical portion in contact with the large diameter portion 60, and as shown in FIG.
A substantially-shaped groove 86 is formed, consisting of a vertical groove 86a through which the liquid 2 passes, and a lateral groove 86b that communicates with the groove 86a and engages with this protrusion, and a large number of grooves 59 for liquid flow. 86c is a protrusion provided in the horizontal groove 86b, and 90 and 91 are liquid flow gaps formed between the vertical portion 61a and the large diameter portion 60.

61b is a horizontal portion having an opening 93 with a diameter smaller than the inner diameter of the spiral body 30A and having a downward protrusion 92 on the periphery, and a downward annular protrusion 87 formed on the lower surface, which pushes out the upper end surface of the filter 30 and closes the opening. The peripheral edge of 93 acts to prevent debris from flying out.

Further, on the outer surface of the lid 61, a rotating handle 61c,
61c is integrally provided in a protruding manner, a protruding first matching mark 61d is formed at a position corresponding to the handle, and further a protruding third matching mark 61e is formed at a position relative to the inner part 86b1 of the groove 86b, An indication ``close'' is placed near the protrusion 61e, and an indication indicating the direction in which the lid 61 should be ``closed'' or ``unscrewed'' is placed at a distant position. A protruding third matching mark 65b indicating the position of the protrusion 62 is formed on the outer periphery of the upper end of the cylindrical portion 29b, and the lid 61 is arranged so as to match the first matching mark 61d and the third matching mark 65b. is fitted into the large-diameter portion 60 of the cylindrical portion 29b, and rotated in the "tighten" direction by holding the handle 61c. Then, the protrusion 62... becomes the horizontal groove 86b.
... and climb over the protrusion 86c into the groove 86.
The lid 61 is fitted into the inner part 86b1 of the lid 61, and the lid 61 is prevented from rotating reliably. At this time, the second joint seal 61e
and the third matching mark 65b match, and the complete closing of the lid 61 can be easily confirmed by the above-mentioned feeling or sound of crossing over. In addition, the first matching mark is the handle 61c,
You can eliminate it by replacing it with 61c.

Further, referring to FIG. 2, the container lid 21b has a material input tube 44 integrally vertically disposed opposite a portion off the center of the cutter 38, and a material input tube 44 is integrally provided on the periphery thereof so as to cover substantially the entire surface of the cutter 38. A regulating plate 41 is integrally provided to protrude in the horizontal direction. The outer edge of this regulation plate 41 is bent downward and the re-cutting blade 4
A hanging portion 41a is formed which is located outside of the extension portions 42 and faces the extension portions 42. This hanging part 41
One or more slits for concentrating the material to fly out are formed in a, and protrusions 94 for holding down the cut material are integrally formed on the outer peripheral surface. Reference numeral 95 denotes a push rod that is inserted into the material input cylinder 41 to push the material, and 96... are protrusions formed obliquely in the direction to discharge the excess waste to the outside of the separation cylinder when the waste is accumulated in excess.

Further, the container lid 21b is fixed in a pressed state onto the main body case 2 with the container 21a in a closed state by a clamp device 97 attached to the main body case 2 as shown in FIG.

() About the liquid extraction part C Reference numeral 119 is a cup for receiving the liquid from the outflow port 25, which has a substantially triangular cross section and a low step part 9 formed in the front corner of the main body case 2 to have a substantially triangular shape in plan.
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. First, the second
As shown in the figure, set it to the ready state for producing use liquid,
An electric motor is driven to charge materials such as fruits and vegetables into the charging cylinder 44 and push them using a push rod 95. Then, the material is grated by the grater blade 39, but large materials such as leather that could not be grated and cut are cut into small pieces by the re-cutting blade 40, and the gap between the regulating plate 41 and the base part 29a is Alternatively, the particles are blown outward in the horizontal direction from the notch of 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 and reaches the inner periphery of the cylindrical portion 29b. After moving upward through the flow gap 58 formed by the protrusions 57a, 57b..., the flow gap 9 between the lid 61 and the cylinder portion 29b is moved upward.
0,91 and flows out of the separation tube 29 into the container 21.
You can take it at a. This liquid flows down from the outlet 25 and is received by the cup 119.

On the other hand, the scraps are sequentially stacked from the inner lower end H of the filter 30 while being held down by the holding projection 41a. When the material is further cut, the material to be cut is also deposited on the inner upper half of the filter 30, and the liquid separated from the material to be cut in the lower part of the horizontal portion 61b of the lid 61 flows into the gap 79-89-90-. It flows out of the separation cylinder 29 through 91 and 69-90-91. Further material is cut to form an opening 93 in the lid 61.
When the lid is stacked on the inside of the diameter, the protrusion 9
6..., the waste is discharged to the outside of the separation cylinder 29.

In order to remove the waste after producing such waste, first stop the electric motor, remove the clamp device, and remove the container lid 21b. Then, the lid 61 is rotated to release the engagement with the cylindrical portion 29b, and the large diameter portion 6
The filter 30 can be easily taken out of the separation tube 29 by inserting a finger into the opening, holding the upper end of the filter 30, and pulling it upward. This filter 30 has debris attached to the lower part of its inner periphery, and by holding both ends of the filter 30 and expanding or contracting it or shifting it laterally, the debris can easily be removed from the inner periphery of the filter. Furthermore, fibers and the like remaining in the gap 69 can be easily washed away by washing with water while the gap 69 is widened.

In the above configuration, the length of the filter 30 in the cylindrical axis direction is formed to be approximately equal to the depth l1 inside the cylindrical portion 29b, and the outer periphery of the filter 30 is supported by the inner periphery of the cylindrical portion 29b, particularly at the upper end. Vibration of the filter 30 in the left and right direction is prevented, and even if the driver forgets to close the lid 61 during operation, the filter 30 can be prevented from popping out from the separation tube 29. Note that if the upper end of the filter 30 protrudes above the cylindrical part 29b in the installed state, the upper end of the filter 30 will vibrate if the lid 61 is not closed and the upper end of the filter 30 will vibrate, which may cause the filter to pop out of the separating cylinder 29. be.

Then, a large diameter portion 60 is provided, and a partial projection 5 is provided.
By supporting the outer periphery of the upper end of the filter 30 with 7c, the filter 30 can be easily taken out.

Furthermore, by blocking relative rotation of the filter 30 on the outer surface 74 side of the filter 30 rather than on the upper and lower end surfaces, the upper and lower end surfaces 70, 70 of the filter 30, the inner bottom surface of the cylindrical portion 29b, and the lid 61 are prevented from rotating relative to each other. There is an advantage that the size, height, etc. of the protrusion 83 can be set regardless of the distance between the gaps 80 and 79 between the protrusion 83 and the lower surface.

Note that the present invention is not limited to the above embodiment, and the projections 82 may be formed not on the filter 30 but on the inner bottom surface of the cylindrical portion 29b and the lower surface of the lid 61. Also, the winding direction of the filter 30 and the separation tube 29
The relationship with the rotation direction may be reversed, or the second rotation direction may be reversed.
As shown in FIG. 9, members 121 and 122 functioning as a lid 61 may be integrally formed at the upper end of the filter 301. One member 121 prevents debris from flying out, and the other member 127 elastically engages with the cylindrical portion 29b.

(F) Effects of the Invention According to the present invention configured as described above, by expanding and contracting the spiral body in the direction of the cylinder axis or shifting it in a direction perpendicular to the cylinder axis direction, the interval of the liquid flow gap can be greatly changed. This makes it easy to separate the waste from the filter, and also allows cleaning with a large liquid flow gap, making it easy to clean the filter and keeping the filter clean at all times. can be kept. Further, by forming a liquid flow gap between the lower end surface of the filter and the bottom surface of the separation cylinder, there are great effects such as an increase in the amount of reduction of use.
