た。(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.

ものである。(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 present invention is characterized in that the helical body has a gap-holding protrusion formed on the surface of the spiral body that defines the flow gap.

で、液流通が阻害されない。 Due to this structure, 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 it in a direction perpendicular to the cylinder axis, 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. Further, since the liquid flow gap does not become less than a predetermined value due to the gap maintaining protrusion, the liquid flow is not obstructed.

る。 As shown in FIGS. 6 to 9, 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. This spiral body 30A is in a state where no force is applied in the direction of contraction in the cylinder axis direction (natural extension state)
As shown in FIG. 6, the molding is performed using a mold so that the gap 69 is expanded, and when the lid 61 is closed, it is compressed and the gap 69 is minimized. When a force is applied in the direction of extension of the cylinder axis, the distance between the gaps 69 is further expanded, and when a force is applied in the horizontal direction, a lateral shift occurs between the steps, which also causes the distance between the gaps 69 to change in the left-right direction. It has the property of expanding. The length of the spiral body 30A in the cylindrical axis direction is longer than the depth l1 of the cylindrical portion 29b even when the lid 61 is in the closed state and in the naturally extended state, making it easy to take out the filter 30.

付着が少なく、掃除が容易となつている。 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 portion 29b are formed. 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 face 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 abutting 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.

5 has a tapered surface 75a, which increases in diameter symmetrically upward and downward from the midpoint 0, as shown in FIG.
75a, the rotation of the separation cylinder 29 allows the dregs to be accumulated from below first, and also facilitates the removal of the dregs from the filter in the downward direction.
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.

When the direction of rotation is counterclockwise x when viewed from above, the winding direction from top to bottom is clockwise when viewed from above. If the winding is reversed to this winding direction, as the separating cylinder 29 rotates, the diameter of the helical body 30A will contract, and at the same time, a force will act in a direction in which the length in the axial direction of the cylinder will increase, and this force will act as a force to remove the lid 61. In some cases, there is a risk that the engaging portion between the lid 61 and the separation tube 29 may be damaged and the lid 61 may be blown off.However, if the winding direction of this embodiment is used, the spiral body 30A may be damaged as the separation tube 29 rotates. Since the force acts in the direction of expanding the diameter of the cylinder and contracting the length in the axial direction of the cylinder, such a drawback is eliminated and the locking structure of the lid 61 can be simplified.
