Description

[Detailed explanation of the idea] [Industrial application field] TECHNICAL FIELD The present invention relates to a compressor-drawn type juicer.

[Conventional technology]

A compression drawing type juicer has been put into practical use by the present applicant in recent years. In this kind of juicer, an outer case having a juice outlet and a waste storage part is placed on top of the juice container, and a rotary squeezing body having a cutter on the upper surface and a circumferential surface formed in a substantially spiral shape is attached to the outer case. The material to be cooked that is pushed in from the material input tube of the case lid, which is removably attached by blocking the top opening of the outer case, is cut by being rotated within the inner case stored in the inner case, and then rotated with the inner case. The juice is compressed between the squeeze body and the filter included in the inner case, and the juice is squeezed out by pressing open the dregs outlet cover, which is attached to the dregs outlet at the bottom of the inner case and is always biased in the closing direction. , the dregs are discharged into the dregs storage section. An annular sealing gasket is sandwiched between the inner case and the case lid to provide a seal.

A conventional example of this seal structure is shown in FIG.
In this structure, a seal gasket C having a shape is fitted, and a case lid D is attached by closing the upper opening of the outer case E, and at the same time, the flat inner surface F of this case lid D is pressed against the lip portion B to seal. In addition,
In the figure, G is the juicer body, H is the juicer container, I
is a rotating squeezing body, J is a material feeding tube, and K is a material pushing rod.

[Problem that the invention attempts to solve]

By the way, during the compression drawing of this type of compressor, the material cut by the cutter on the upper surface of the rotary drawing body I is circumferentially distributed along the upper surface of the rotating drawing body I and the flat inner surface F of the case lid D adjacent thereto. It moves with considerable force. Therefore, in the conventional seal structure described above, the cut material that is moved along the flat inner surface F of the case lid D that presses the lip portion B of the seal gasket C is directly and forcefully applied to the case lid D. There was a risk that it would enter between the contact area between the inner surface F and the lip portion B, impairing the sealing performance.

[Means for solving problems]

The present invention is a compression draw type regulator that has a lip portion that elastically deforms an annular seal gasket sandwiched between a case lid and an inner case inwardly and presses it against the inner surface of the case lid. In addition, the above-mentioned problems of the conventional art are solved by providing a lip cover on the inner surface of the case lid at a position slightly away from the lip.

[Effect]

In the present invention, the case lid is attached to close the upper opening of the inner case, and at the same time, the inner surface of the case lid presses the lip portion of the annular seal packing inward to cause elastic deformation. As a result, the seal packing is sandwiched between the inner case and the case lid, and the lip portion is pressed against the inner surface of the case lid to form a seal structure. The material cut as the rotary aperture body rotates is moved vigorously in the circumferential direction between the upper surface of the rotary aperture body and the rotation of the case lid. Direct contact with the inner surface can be prevented by covering the lip. Therefore, it is possible to prevent the cut material from entering the seal portion and maintain sealing performance.

It is designed to be supplied.

In the above description, all the parts other than the drive coupling 4 of the drive mechanism and other parts whose materials are specially specified are made of synthetic resin.

Next, the operation of this embodiment will be explained.

First, the outer case 8 is fitted into the case fitting part 2 of the regulator main body 1, the engagement protrusion 9 is engaged with the engagement recess 6, and the cylindrical part 10 is fitted into the engagement protrusion 7. The inner case 20 is fitted into the thus supported outer case 8, and positioned by fitting with the fitting step portion 19, the upper annular portion 24, and the like. Next, the rotary aperture body 30 is fitted into the inner case 20.

Then, the driven coupling ring 35 is inserted into the through hole 18.
and 34 and is engaged in the cylindrical portion 10 with the drive coupling 4 of the drive mechanism. At the same time, the bearing 36 is fitted into the annular step 19 of the outer case 8, and at the same time the packing 37 is pressed against the inner bottom surface of the annular step 19. Note that in this stored state, the lower end of the rotary body 31 of the rotary aperture body 30 is slightly away from the bottom surface of the inner case 20.

Then, after fitting the seal packing 40 into the packing fitting groove 38 of the inner case 20, the sixth
As shown in the figure, the case lid 44 is placed on the upper surface of the juicer body 1, and the bearing 45 is connected to the rotary aperture body 30.
It fits into the upper end of the rotating shaft 32 of. Then, the case cover 44 is attached and fixed to the outer case 8 by rotating the cover 44 in the direction of the arrow in FIG. Then, the rotating shaft 32 of the rotating aperture body 30 is rotated by the upper and lower bearings 4.
5 and 36, it is stably supported in a dual-supported state.

Moreover, by attaching the case lid 44 as described above, the lid 44 is drawn downward and its inner surface is brought close to the upper surface of the rotary body 31 of the rotary aperture body 30 with a small gap. In particular, by pulling the case lid 44 downward, the seal gasket 40 is brought into contact with the upper edge of the inner case 20 and the case lid 4.
It is sandwiched between the inner surface of 4 and the inner surface of 4. In this case, the seal packing 40 is elastically deformed as shown in FIGS. 1 and 2.

That is, as the case lid 44 moves downward, the upper and lower lip portions 41 of the seal packing 40
contacts the annular inclined surface 42 of the inner case 20 and the annular inclined surface 46 of the case lid 44, and is elastically deformed while being more reliably guided inward by these, and then the tip side of the lip portion 41 contacts the annular inclined surface 46 of the case lid 44. Annular flat surfaces 43 and 47 connected to 42 and 46
is pressed against. As described above, when the seal packing 40 is completely clamped, the tip of the lower lip 41 is close to the base of the upward rib 39 of the inner case 20, and the tip of the upper lip 41 is close to the case lid. 44 is adjacent to the lip portion cover 48.

Finally, the juice container 11 is placed between the stand 3 of the juicer main body 1 and the outer case 8, the juicer is connected to a power source, and the operating section 5 is then operated to operate the drive mechanism.

In the set state as described above, the user puts the prepared ingredients to be cooked into the material input tube 49, and then uses the material pushing rod 50 to push the ingredients to the rotary squeezing body 30.
Press it onto the top surface.

Then, the material is cut and crushed by the cutter 33 of the rotary drawing body 30 that rotates at a speed of about 3,000 revolutions per minute, and is sent out toward the outer circumferential direction of the rotary body 31. The rotating body 3 of the inner case 20 and the rotary constrictor body 30 is guided downward along the material guide portion 22 of the
1 is introduced into the aperture gap between the

The cut material introduced in this way (hereinafter referred to as cutting material) is compressed by the outer circumferential surface of the rotating body 31, so that the youth content is extracted.
This juice portion (juice) is filtered by a filter 21 and flows out into the juice chamber 13. Then, this juice portion flows out of the youth outlet 17 and is stored in the youth container 11 disposed below the outer case 8 through the groove 12a. Further, the material waste is sent downward by a spiral groove on the circumferential surface of the rotating body 31, and the waste outlet cover 26 is pushed open from the waste outlet 23 of the inner case 20 against the biasing force of the spring 28. The waste is discharged to the waste storage section 16 of the outer case 8.

By the way, in the above-described compression drawing, the cutting material fed in the circumferential direction of the rotating body 31 from between the upper surface of the rotating body 31 of the rotating drawing body 30 and the case lid 44 adjacent thereto is transferred to the inner surface of the case lid 44. Although the cutting material is moved along the cutting surface with considerable force, it is blocked by the lip cover 48 on the inner surface of the case lid 44. This prevents the cutting material from directly hitting the contact area between the tip of the upper lip portion 41 of the seal packing 40 and the annular flat surface 47 of the case lid 44 and entering between the upper lip portion 41 and the annular flat surface 47. Prevented.

Therefore, leakage of moisture to the outside along the inner surface of the case lid 44 can be reliably prevented, and the sealing performance on the case lid 44 side can be improved.

Moreover, since the protruding height of the lip portion cover 48 is made slightly higher than the thickness of the tip end side of the upper lip portion 41, it is possible to easily return the cut material etc. to the inside as shown by the arrow in FIG. Therefore, it is possible to prevent the possibility that the inside of the seal packing 40 is completely filled with cutting material and the like, and moisture leaks out from between the inner case 20 and the case lid 44 due to the pressure thereof.

Note that the lower lip portion 41 of the seal packing 40
Due to the existence of the upward rib 39, the acting force of the cutting material on the side of the contact area with the annular flat surface 43 of the inner case 20 is not as large as that on the case lid 44 side. Since the lip portion 41 is covered, it is possible to prevent cutting material from entering between the lower lip portion 41 and the annular flat surface 43 and impairing the sealing performance.

Although the above-mentioned embodiment is constructed as described above, in the embodiment of the present invention, the outer case, the juice outlet, the dregs storage section, the inner case, and the rotary diaphragm body are , the specific structure and shape of the cutter, filter, case lid, material input cylinder, seal packing, lip part, lip part cover, etc.
Of course, the position, material, etc. can be configured and implemented in various ways without being restricted to the one embodiment described above.
