Description

[Detailed explanation of the idea] [Industrial application 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 arranged on the juice container, and a rotary squeeze 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 through 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 in the inner case housed in the inner case, and then rotated with the inner case. The juice is compressed between the squeezing body and squeezed by a filter included in the inner case, and the lees outlet lid, which is attached to the lees outlet at the bottom of the inner case and is always biased in the closing direction, is pushed open. , the dregs are discharged into the dregs storage section. An annular seal 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 sealing 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 part 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]

However, since the seal gasket C that seals between the inner case A and the case lid D has a lip portion that projects diagonally upward from the inner upper edge as described above, the case lid D cannot be attached to the seal gasket C. It tends to be difficult to ensure a larger amount of deflection. For this reason, for example, when the material is cut between the upper surface of the rotary wringer I and the inner surface F of the case lid D adjacent thereto due to too much material to be cooked, the inner surface F of the case lid D There was a risk that the sealing performance between the contact portion with the lip portion B would be impaired.

[Means for solving problems]

In order to solve the above-mentioned conventional problems and improve the usability of a compression drawing type pump, the present invention has an upwardly facing lip part and a downwardly facing lip part, so that the upper and lower parts are approximately symmetrical. The bottom surface of the annular gasket fitting groove formed on the upper edge of the inner case and the inner surface of the case lid are provided with an annular gasket with the lip portion facing inward, facing the seal gasket. In addition to providing an inclined surface, a flat surface connected to the inclined surface and pressed against the tip end of the lip portion is provided.

[Effect]

In the present invention, the case lid is attached to close the upper opening of the outer case, and at the same time, the upward and downward lip parts of the annular sealing gasket are pressed against the inner surface of the case lid and the gasket fitting while receiving the pressing force in the compression direction from the case lid. Since it is guided so as to fall inwardly along the annular slope formed on the bottom of the joint groove and is greatly bent, it does not twist or turn over even though the lip section is provided along the vertical direction. The tip portion is strongly pressed against the inner surface of the case lid and the flat surface of the bottom surface of the seal fitting groove, thereby forming a sealing structure between the inner case and the case lid. Therefore, sealing performance can be improved. Moreover, since the upper and lower lip parts of the seal packing are bent, the compression dimension of the packing is large, making it possible to easily attach and remove the case lid.The seal packing is vertically symmetrical, and the seal fitting groove can be inserted into the fitting groove. Since it is possible to eliminate the directionality when fitting, usability can be improved.

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.

After this, the seal packing 42 is fitted into the packing fitting groove 38 of the inner case 20. In this case, the seal packing 42 is vertically symmetrical, and annular inclined surfaces 40, 47 and annular flat surfaces 41, 48 correspond to the upper and lower lip portions 43, 44.
However, since they are provided on the inner case 20 and the case lid 45, there is no directionality when attaching the seal packing 42, and it can be easily handled. Next, as shown in FIG. 6, the case lid 45 is placed on the upper surface of the pump main body 1, and its bearing 46 is fitted to the upper end of the rotating shaft 32 of the rotary aperture body 30. Then, by rotating the lid 45 in the direction of the arrow in FIG. 6, the case lid 45 is attached and fixed to the outer case 8. Then, the rotating shaft 32 of the rotary aperture body 30 is stably supported by the upper and lower bearings 46, 36 in a dual-supported state.

Moreover, by attaching the case lid 45 as described above, it goes without saying that the lid 45 is pulled downward and its inner surface is brought close to the upper surface of the rotating body 31 of the rotary aperture body 30 with a small gap. In particular, by pulling the case lid 45 downward, the seal gasket 42 connects to the upper edge of the inner case 20 and the case lid 4.
It is sandwiched between the inner surface of 5 and the inner surface of 5. In this case, the seal packing 42 is elastically deformed as shown in FIGS. 1 and 2.

That is, as the case lid 45 moves downward, the upward lip portion 43 of the seal gasket 42
The downwardly directed lip portion 44 is elastically deformed by contacting the annular inclined surface 40 of the inner case 20 and the annular inclined surface 47 of the case lid 45, respectively, and is more reliably guided inward by these, and then the lip portions 43, 44 The tip side is the annular inclined surface 40,
It is pressed against annular flat surfaces 41 and 48 that are connected to 47.

In this case, the annular inclined surfaces 40, 47 as described above
The guiding action prevents the upward and downward lip portions 43 and 44 from twisting.
These lip portions 43, 44 can be uniformly compressed over the entire circumference, and can be surely brought inward to be brought into pressure contact with the annular flat surfaces 41, 48, and the tips of the lip portions 43, 44 can be turned over. can be prevented. Furthermore, since the lip portions 43 and 44 are elastically deformed as described above under the pressure action along the compression direction, it is possible to greatly bend the lip portions 43 and 44 and bring them into strong pressure contact with the annular flat surfaces 41 and 48. can. Therefore, sealing performance is improved.

Further, since the seal packing 42 is sandwiched between the inner case 20 and the case lid 45 in the above manner by bending the vertical lip portions 43 and 44 provided on the upper and lower sides thereof, The compressed size of the seal packing 42 as a whole is large. As a result, the compressive force of the seal packing 42 by the case lid 45 can be reduced, and therefore the case lid 45 can be easily attached and removed.

As described above, when the seal packing 42 has been clamped, the tip of the lower lip 44 is close to the root of the upward rib 39 of the inner case 20, and the tip of the upper lip 43 is close to the case lid. 45
It is close to the lip cover 49 of.

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 above-mentioned set state, the user puts the prepared ingredients to be cooked into the material input cylinder 50, and then uses the material pushing rod 51 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 8a. 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 and juice that are fed in the circumferential direction of the rotating body 31 from between the upper surface of the rotating body 31 of the rotating squeezing body 30 and the case lid 45 adjacent thereto are transferred to the case lid 45. Although the cutting material and liquid are moved with considerable force along the inner surface, the above-mentioned seal structure formed by the upper lip 43 of the seal packing 42 and the annular flat surface 48 of the case lid 45 prevents the cutting material and liquid from moving along the inner surface. , the lower lip portion 44 of the seal packing 42 and the inner case 20 are reliably prevented from leaking to the outside.
The sealing structure formed by the annular flat surface 41 reliably prevents leakage to the outside.

Further, after use, it is disassembled in the reverse order of the assembly procedure described above, and each part other than the regulator body 1 is washed and maintained.

Although the above-mentioned embodiment is constructed as described above, in carrying out the present invention, the outer case, the waste outlet, the waste storage section, the inner case, and the packing fitting groove may be The specific structures, shapes, positions, materials, etc. of the rotary diaphragm, cutter, filter, case lid, material input cylinder, seal packing, lip, annular inclined surface, flat surface, etc. are not limited to the above-mentioned example. Of course, the present invention can be configured and implemented in various ways without any modification.
