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-teeth shape to form vertical slits for discharging a large number of liquids, and debris adheres to and accumulates 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 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) Purpose of the Invention In view of the above-mentioned drawbacks, it is an object of the present invention to provide an easy-to-use juicer by making it easy 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 that is equipped with a cylindrical filter that separates waste and liquid, and that collects the waste in the centrifugal separation cylinder, wherein the cylindrical filter has a helical body having a spiral liquid flow gap that allows the interval to be expanded. The spiral body is characterized by having a spring property so that it is constantly contracted in the direction of the cylinder axis, and configured so that adjacent steps are substantially in contact with each other without applying any force in the direction of the cylinder axis. It is something to do.

Due to this configuration, waste adheres to and accumulates on the inner circumference of the filter, but by expanding and contracting the filter in the direction of the cylinder axis or deforming the cylinder axis in the perpendicular direction, the interval of the liquid flow gap changes greatly, so that the waste adheres to and accumulates on the inner circumference of the filter. If the filter is washed with the filter easily separated from the filter and the gap is widened, the debris stuck in the gap can be easily washed away. Furthermore, when the filter is pulled up after the generation of waste, the amount of stretch of the filter is small, making it easy to take out the filter.

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 around the outer periphery of the support part 32 of the base part 29a, and the cylindrical part 29b is held between the ring body 29c and the horizontal part 31,
This ensures the connection between both 29a and 29b.

The ring body 29c is connected to the protrusion 36 of the base portion 29a...
A protrusion 51 having a slope that engages with the bayonet is formed on the inner circumference, and a receiving surface 53 for receiving the lower end of the fitting portion 47 is formed on the upper end. Note that the support portion 32 and the ring body 29c may be connected by a threaded groove (not shown) instead of bayonet engagement.

Reference numeral 56 denotes the inner circumferential surface of the cylindrical portion 29b to which the filter 30 is attached, and has a tapered shape with a larger diameter at the top so that the separated liquid can easily rise. Forming a protrusion 57...
A liquid flow gap 58 is provided between the filter 30 and the outer circumferential surface of the filter 30.

59 is a filter locking protrusion formed at the lower end corner of the inner circumferential surface 56 to prevent rotation of the filter 30, and is formed on an extension of the protrusion, but is not limited to this. .

Note that the liquid flow gap 58 may be provided by forming a protrusion (not shown) on the outer circumference of the filter 30 instead of forming a protrusion on the inner circumferential surface 56.

Reference numeral 60 denotes a large diameter portion formed at the upper end of the inner circumferential surface 56, on which locking protrusions 62 of a lid 61 to be described later are integrally protruded inward.

63 is approximately L across the side and bottom surfaces of the cylindrical portion 29b.
With a fluid balancer formed in a letter shape, the side surfaces of the cylindrical portion 29b are formed into double walls 64 and 65 with an opening at the bottom, and
This lower opening is closed with a ring-shaped bottom cover 66 to form a sealed space, and an appropriate number of vertical resistance plates 67 are integrally provided in this space projecting from the outer wall 65 side, and a balancer is installed in this space. A suitable amount of liquid 68 is enclosed. 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 welded and sealed, and this concave-convex fit improves sealing performance. 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. 4 and 5, the spiral filter 30 is composed of a multi-stage cylindrical spiral body 30A made of synthetic resin, for example, ABS resin, and a spiral liquid flow gap 69 is formed between each stage. It has spring properties so that it constantly contracts in the direction of the cylinder axis. This helical body 30A is formed by molding or extrusion so that when no force is applied in the direction of the cylinder axis (excluding its own weight), adjacent steps are in approximate contact (including contact) as shown in FIG. It is formed by molding, and when a force is applied in the direction of extension of the cylinder axis from the state shown in the figure, the interval of the gap 69 is expanded, and when a force is applied in the horizontal direction, lateral displacement occurs between the steps. This also has the property of expanding the interval of the gap 69 in the left-right direction.

Furthermore, by configuring the uppermost stage 30a and the lowermost stage 30b of the spiral filter 30 so that the end surfaces 70, 70 are flat surfaces with no steps (excluding the projections 82, which will be described later), the inner surface of the lid 61 and the cylindrical part 29b are A large gap is not formed between the inner bottom surface and the waste is prevented from flowing out. The height dimension of the above cross section can be changed by gluing ring-shaped bodies for height adjustment on the top and bottom surfaces of the spiral body with the same cross-sectional shape, or by changing the cross-sectional shape with a mold. However, in this embodiment, the latter is adopted. and end 7
1 and 71 are sufficiently thick in the axial direction of the cylinder to ensure strength at the ends, and protruding pieces 72 are provided at the ends 71 and 71.
A groove 73 into which the protruding piece 72 is fitted is formed in the mating surface corresponding to the ends 71, 71, so that even if a slight force is applied to the ends 71, 71 when pulling up the filter 30, the cross section will not change. This small end 71,7
1 is constructed so as not to be damaged, and the corner portions are rounded so that the protruding piece 72 and the groove 73 are disengaged when a force exceeding a predetermined level is applied. Since this locking is performed on the outer peripheral side of the filter 30, there is less adhesion of debris and cleaning is easy.

Further, the spiral body 30A has an outer diameter slightly smaller than the inner diameter of the cylindrical portion 29b (the tips of the protrusions 57...), and the outer circumferential surface 74 is in contact with the protrusions 57... and the inner circumferential surface 7
5 has tapered surfaces 75a, 7 whose diameter increases symmetrically upward and downward from the midpoint 0, as shown in FIG.
5a, the rotation of the separation cylinder 29 allows the scum to accumulate from below, and also facilitates the downward removal of the scum from the filter.
In the embodiment, the filter 30 is formed to have a larger diameter toward the top and bottom in order to eliminate the vertical directionality, but if it has directionality, it would have a taper that increases in diameter from the top to the bottom. It is sufficient if it is formed on a surface.

The cross-sectional shape of each step of the spiral body 30A is such that the upper and lower corners of the outer surface are cut out 76a, as shown in FIG.
76a, thereby reducing the flow resistance of the liquid flowing out from the gap 69, and making the inner surface 76b a substantially vertical flat surface to facilitate the movement of waste. Note that the form of this notch is not limited to that shown in the drawings.
Furthermore, if it is not necessary to improve the mobility of debris, the inner surface may be curved.

Liquid flow gap 7 between the top surface and
9,80 is formed. This gap is a constant value (for example, 0.4 mm) between each stage when the lid is closed as shown in the same figure.
In order to prevent the helical gap 69 from becoming narrower, spacing protrusions 81 are provided on the lower surface of the helical body 30A at equal intervals in the longitudinal direction of the gap 69, all having the same height over substantially the entire width in the radial direction of the flat surface 77b. The spiral body 30A is formed in the gaps 79 and 80.
Similar spacing-maintaining protrusions 82 having the same height as the protrusions 81 are formed on the upper and lower end surfaces of the holder. These protrusions 81..., 82... make the ease of liquid outflow approximately equal over 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 spiral body 30A has a cylindrical portion 29b and a lid 6.
Rotation is prevented by concave-convex engagement between the base plate and the base plate 1. That is, a large number of substantially V-shaped engagement grooves 83 having the same shape at the top and bottom are formed at the outer corners of the top and bottom stages of the spiral body 30A over a range of a predetermined angle (approximately 60 degrees in this embodiment). A pair of substantially V-shaped protrusions 84 are formed in the upper grooves 83 at a predetermined angle (approximately 60 degrees in this embodiment) at the inner corner of the lid 61. By fitting, rotation is prevented between the cover 61 and the separating cylinder 29 by fitting the protrusions 59 of the cylindrical portion 29b into the grooves 83 at the lower end. There is.

Further, as shown in FIGS. 3 and 6 to 8, the lid 61 is fitted and locked into the upper end large diameter portion 60 of the cylindrical portion 29b to prevent the filter 30 from coming off and to be stored on the inner periphery of the filter 30. It is configured to have a function of preventing debris from flying out. Reference numeral 61a denotes a cylindrical vertical portion in contact with the large diameter portion 60, and projections 85 are provided at equal intervals on the outer circumferential surface, and a vertical groove 86a through which the projection 62 of the large diameter portion 60 passes between the projections 85 and 85, and this groove. A large number of grooves 86 are formed at equal intervals, and the inner circumferential surface 87 is tapered to expand downward, and the outer circumference of the upper end of the spiral body 30A is formed in a large number at equal intervals. A vertical protrusion 88 is formed in contact with the spiral body 30A, and a liquid flow gap 89 is formed between the spiral body 30A and the spiral body 30A. Also, there are liquid flow gaps 90, 9 between the inner surface of the large diameter portion 60 and the vertical portion 61a.
1 is formed. Reference numeral 61b denotes a horizontal portion having an opening 93 having a diameter smaller than the inner diameter of the spiral body 30A and having a downward protrusion 92 on the periphery.The lower surface presses the upper end surface of the filter 30, and the periphery of the opening 93 acts to prevent debris from flying out. Eggplant.

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 the regulating plate 41 is bent downward to form a hanging portion 41a located outside the re-cutting blades 40 and facing the extending portions 42. This hanging portion 41a is formed with one or more slits for concentrating the material and protruding from it, and is also integrally formed with projections 94 for pressing the material cut on the outer peripheral surface. 95 is a push rod inserted into the material input cylinder 41 to push the material;
6 is a protrusion formed obliquely in the direction to discharge the excess waste to the outside of the separation cylinder when excessive waste is accumulated.

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

() About the liquid take-out 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 is placed on the low step part 9 formed in the front corner of the main body case 2 and having 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. Before producing liquid, as shown in FIG.
Filter 30 in which 72 is engaged with grooves 73, 73
is installed inside the cylindrical portion 29b. Then, the lid 61 is fitted into the large diameter portion 60 of the cylindrical portion 29b, and the protrusion 62
... into the horizontal groove 86b from the vertical groove 86a... and the lid 61
When viewed from above, rotate the protrusions 62 clockwise (opposite to the rotational direction of the separation tube 29) to align the protrusions 62 with the lateral grooves 86b.
It is coupled to the cylindrical portion 29b by positioning it in the inner part of the cylindrical portion 29b. In this state, the filter 30 is prevented from popping out. Then, the lid 61 is closed by the projections 82 on the upper end.
A gap 79 between the inner surface and the upper end surface 70 of the filter 30
However, the gap 69 is maintained at a constant interval by the protrusions 81, and the gap 80 is maintained at a constant interval by the protrusions 82 at the lower end. At the same time, the lower end of the filter 30 is locked to the cylindrical part 29b by the engagement between the projections 59 and the grooves 83 at the lower end, and the upper end of the filter 30 is locked by the engagement between the projections 84 and the grooves 83 at the upper end. 61, the filter 30 is prevented from rotating vertically.

Next, the container lid 21b is closed on the receiver 21a, and the clamp device 97 is rotated to engage the lid 21b, thereby completing the liquid production preparation state. Then, by driving the electric motor, materials such as fruits and vegetables are introduced into the input tube 44 and pushed by the push rod 95. Then, the material is grated by the grater blade, but large materials such as leather that could not be grated and cut are cut into pieces by the re-cutting blade 40, and the gap between the regulating plate 41 and the base 29a or 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 is removed from the tapered surface 75 of the filter 30.
While descending along line a, it is separated into waste and liquid, and the liquid flows through the gaps 80 and 69 and reaches the inner periphery of the cylindrical portion 29b, which is formed by the protrusions 57. After moving upward through the flow gap 58,
Flow gaps 90, 91 between the lid 61 and the cylindrical portion 29b
The liquid flows out of the separation tube 29 through the separation cylinder 29 and is received in the container 21a. This liquid flows down from the outlet 25 and is received by the cup 119.

On the other hand, waste portions are accumulated sequentially from the inner lower end H of the filter 30 while being held down by the holding projection 41a, resulting in an accumulation state as shown in FIG. 10. When the material is further cut, the material to be cut is also accumulated in the upper inner half of the filter 30, and the liquid separated from the material to be cut in the lower part of the horizontal part 61b of the lid 61 is collected in the gap 79-8.
It flows out of the separation cylinder 29 through 9-90-91 and 69-90-91. This liquid leaks out from the lid 61.
This can be done smoothly by tapering the inner peripheral surface 87 of the . When the material is further accumulated inside the diameter of the opening 93 of the lid 61 to be cut, the scraps are discharged to the outside of the separation tube 29 by the protrusions 96.

During this generation of waste, the particles adhering to the inner periphery of the filter 30 try to expand the liquid outflow gap 69 due to centrifugal force, but since the upper end of the filter 30 is held down by the lid 61, this gap is It remains constant without spreading. As a result, the waste is prevented from flowing out of the filter 30 through the gap 69, and a large amount of waste is prevented from being mixed into the liquid.

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, when the lid 61 is rotated to disengage from the cylindrical portion 29b, the filter 3
The filter 30 can be easily taken out of the separation tube 29 by holding the upper end of the filter 30 and pulling it upward (see FIG. 10). When the filter 30 is taken out, since spring forces F1, F2, etc. are always acting on the filter 30 in the cylinder axis contraction direction, the extension of the filter 30 in the cylinder axis direction is suppressed, and the filter 30 can be taken out easily. This filter 30 has debris K attached to the lower part of its inner periphery, and by holding both ends of the filter 30 and expanding and contracting it as shown in FIG. 9, as well as shifting it laterally, the mass of debris K can be removed. Easily detaches from the inner periphery of the filter.

In addition, in order to clean the inside of the separation cylinder 29, the base part 2
9a and the connector 11, and separate the separation tube 29.
After removing the ring body 29c, the inside can be washed with water, but cleaning becomes easier by removing the ring body 29c from the base portion 29a and separating the base portion 29a and the cylindrical portion 29b.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and for example, a part to prevent debris from popping out may be formed at the upper end of the inner circumference of the filter 30. Also, filter 30
The spiral body 30A may be formed hollow, and the cross-sectional shape may be a shape other than that shown. Also, the gaps 69, 7
Although it is preferable that the projections 81, 82, . . . 82 for maintaining the spacing shown in FIG.

(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. In addition, when taking out the filter after the generation of youth, a relatively large spring force is always applied to the filter in the direction of cylinder axis reduction, so the extension of the filter in the cylinder axis direction can be suppressed and the filter can be taken out easily, which has great effects. demonstrate.
