Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a centrifugal separator for a juicer.

Conventionally, this type of centrifugal separator has been provided with a metal filter made of a thin metal plate with a large number of holes formed therein, but since the inner surface of this metal filter is smooth, it cannot be shredded with a cutter. The shredded material is slippery, the retention time is short, and the juice extraction rate is low, and debris gets stuck in the pores, making it extremely difficult to clean.

For this reason, it has been considered to use a metal filter as a simple filter frame and attach a cloth filter to the two inner surfaces of the filter frame. However, the centrifugal separation section rotates at extremely high speeds, and ordinary cloth would stretch and be unusable. The present invention has been made in view of the above points, and it is an object of the present invention to provide a centrifugal separator for a juicer that improves the juice squeezing efficiency, facilitates cleaning of waste, and does not cause any problems even when using a cloth filter. The purpose is to

In the present invention, a truncated cone-shaped filter frame having a large number of holes and extending upwardly is attached to a basket stand, a support part is provided that is detachably attached to the basket stand, and the support part is used as the lower edge of the filter frame. A cloth filter is provided to be joined to the inner surface of the frame, and warp yarns whose lower ends are fixed to the support portion are threaded in the vertical direction of the cloth filter.

Therefore, due to the high-speed rotation, a large upward tensile force acts due to the weight of the cloth filter itself and the contact pressure of the pongee cut object, but since the warp exists in the direction in which this force is applied, the cloth filter itself does not stretch. This prevents the cloth filter from stretching and causing changes in the mesh, and from interfering with the lifting of shredded materials, allowing the machine to be used in the same condition as the cloth filter is installed at all times. Since the inner surface friction of the pongee cut material is large, it is designed to suppress the rising speed of the pongee cut material to improve the drawing rate, and also to prevent debris from getting stuck in, making it easy to clean. One example is the first
This will be explained based on the drawings to FIG.

First, a motor 2 is built into the main body 1, and this motor 2
A rotary plate 4 is fixed to the upper end of the motor shaft 3, and a mounting table 6 on which a juice cup 5 is mounted is formed on one side of the main body 1. A juice case 7 is detachably provided on the upper part of the main body 1, and a waste reservoir 8 is formed on the negative side of the juice case 7. At the top of the juice case 7, an input port 9 is provided.
A lid 10 having a shape is removably attached. A basket stand 11 is detachably provided on the rotary plate 4, and a filter frame 12 is fixedly attached to the basket stand 11.

The filter frame 12 is composed of a frame body 13 made of a thin metal plate or plastic in which a large number of holes are formed, and a ring-shaped frame body 14 integrally formed on the top of the frame body 13. Next, a truncated conical cloth filter 15 is attached to the inner surface of the filter frame 12. The cloth filter 15 is made of thermofusible fibers such as polyacetal resin, and a ring-shaped support portion 16 made of a material such as vinyl chloride is integrally provided at its lower end.
This support portion 16 is fixedly fixed to the basket stand 11 by a detachable cutter stand 17, and a cutter 18 is fixed to the upper surface of this cutter stand 17. The material 19 of the cloth filter 5 may be made in any way as long as it is relatively non-stretchable; It is integrated with the material 19 by thermal welding. The end edge 22 of the fan-shaped member 21 is then heat welded to form a truncated cone shape, and the support portion 16 is formed at the lower end as described above. In such a configuration, fruits etc. inputted from the input port 9 are cut into pieces by the cutter 18, and the cut pieces collide with the cloth filter 15 and gradually rise due to centrifugal force.

Since the friction on the inner surface of this cloth filter 15 is large, the rising speed of the pongee cut material is small, and the juice is sufficiently squeezed out.
The squeezing rate is high, and the waste is discharged into the waste collection part 8. In this process, the cloth filter 5 is rotating at an extremely high speed, and an upward tensile force is generated due to the weight of the cloth filter 5 itself containing moisture and the upward force caused by the pressure saddle of the pongee cut material. Since the warp threads 20 are provided in the direction in which the force acts, the warp threads 20 serve as reinforcing members and the fabric filter 1
The growth of 5 itself is extremely small. Therefore, the mesh of the cloth filter 15 does not change, and juice of uniform quality can be obtained. Furthermore, since there is no stretch, the upper edge portion of the cloth filter 5 does not overlap with the frame 14, and there is no possibility that the movement of the waste is stopped at this portion and unbalanced rotation occurs. In addition, since the mesh of the cloth filter 5 is small,
Cleaning is extremely easy, with no debris getting stuck in. In the present invention, since the cloth filter is bonded to the inner surface of the filter frame as described above, the rising speed of the pongee cut material is suppressed, the juice squeezing rate can be improved, and there is no scum sticking. It is easy to clean, and in particular, since the warp threads are threaded in the vertical direction where tensile force is applied, the cloth filter itself does not stretch, and as a result, the mesh of the cloth filter does not change and is homogeneous. It has the effects of being able to obtain juice, not inhibiting the rise of the pongee cut material, and improving durability.
