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 juicer, an outer case having a juice outlet and a waste accommodating portion is placed 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. After cutting the material to be cooked, the material is compressed between the inner case and the rotary squeezing body, and the juice is squeezed by the filter of the rotary squeezing body. The scum is discharged into the scum storage section by pushing open the scum outlet cover, which is attached to the scum outlet at the bottom of the case so as to completely cover it and is always biased in the closing direction. .

[Problem that the invention attempts to solve]

However, in this compression drawing type jusa,
When cooking ingredients with a lot of fruit juice and soft flesh, such as ripe tomatoes, the scum from the cut material is drawn into the squeezing gap formed between the inner case and the circumferential surface of the rotating squeezing body. The cut material moves freely within the hole and is not easily discharged, resulting in a reduction in the amount of cut material fed into the aperture gap.
There was a problem that it took a lot of time to narrow down the aperture.

[Means for solving problems]

The present invention, in a compression drawing type juicer, provides a notch in a part of 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, or The above-mentioned conventional problems are solved by providing a narrow discharge gap between the inner case and the bottom plate of the outer case housing the inner case.

[Effect]

In the present invention, when the rotary squeezer is rotated to cook ingredients with a lot of fruit juice and soft pulp, part of the pomace of the cutting material that moves in the squeezing gap between the inner case and the circumferential surface of the rotary squeezer will be removed. can be successively discharged from below the throttle gap to the dregs storage section through a notch in the dregs outlet cover or a discharge gap provided in place of the notch.
Therefore, the performance of supplying the cut material to the squeezing gap is improved, and it is possible to squeeze a predetermined amount of material to obtain juice in a short time.

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 26, the upper annular portion 20a, and the like. Next, the rotary aperture body 32 is fitted into the inner case 20.

Then, the driven coupling ring 37 is inserted into the through hole 18.
and 36 and is engaged in the cylindrical portion 10 with the drive coupling 4 of the drive mechanism. At the same time, the bearing 38 is fitted into the annular step 19 of the outer case 8, and at the same time the packing 39 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 33 of the rotary aperture body 32 is slightly away from the bottom surface of the inner case 20.

After that, after fitting the seal packing 41 into the packing fitting groove 40 of the inner case 20, the case lid 42 is placed in a diagonally shifted position with respect to the outer case 8, and the bearing 43 is attached to the rotating throttle body 32. It fits onto the upper end of the rotating shaft 34 from above. Then, the case cover 42 is attached and fixed to the outer case 8 by rotating the cover 42 counterclockwise. As a result, the rotating shaft 34 of the rotary aperture body 32 is stably supported by the upper and lower bearings 43 and 38 in a dual-supported state. This packing 41 is sandwiched between the upper edge of the inner case 20 and the inner surface of the case lid 42.

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 port 44, and then uses the material pushing rod 45 to push the ingredients through the rotary squeezing body 32.
Press it onto the top surface.

Then, the material is cut and crushed by the cutter 35 of the rotary aperture body 32 that rotates at a speed of about 3,000 revolutions per minute, and is sent out toward the outer periphery of the rotary body 33. The rotating body 3 of the inner case 20 and the rotary constrictor body 32 is guided downward along the material guide portion 22 of the
It is introduced into the aperture gap between 3 and 3.

The cut material introduced in this way (hereinafter referred to as cutting material) is compressed by the outer peripheral surface of the rotating body 33, 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 33, and the waste outlet cover 27 is pushed open from the waste outlet 23 of the inner case 20 against the biasing force of the spring 29. The waste is discharged to the waste storage section 16 of the outer case 8.

In the above-mentioned cooking, if the material to be cooked has a lot of fruit juice and soft pulp, such as a ripe tomato, the scum of the cutting material is trapped between the inner case 20 and the rotating body 33. It moves freely within the throttle gap, but since a notch 31 is formed in a part of the dross outlet cover 27, the dross sent to the lower side of the throttle gap through this notch 31 is stored. It can be easily discharged into the section 16. Therefore, the cutting material supply performance is improved and the drawing time can be shortened.

Moreover, in the case of this embodiment, since the above-mentioned notch 31 is provided on the low-pressure side of the dregs outlet 23, when juice is made from a normal material other than the material with a lot of fruit juice and soft pulp as described above, the dregs outlet can be used. Directly insert the notch 31 without pushing the lid 27 open.
The amount of pomace discharged from the machine can be minimized. Therefore, the effect of the waste outlet cover 27 biased by the spring 29, that is, the effect of increasing the internal pressure of the inner case 20, is not significantly impaired, and a decrease in the efficiency of compression throttling can be prevented as much as possible.

After use, the device is disassembled by reversing the assembly procedure described above, and all parts other than the pump body 1 are washed and maintained.

Although the above-mentioned embodiment is constructed as described above, in the present invention, instead of the above-mentioned notch 31, a narrow discharge gap is provided between the lower end of the waste outlet cover 27 and the bottom plate portion 8a of the above-mentioned outer case 8. It may also be carried out.

In addition, when implementing the present invention, unless it is contrary to the gist of the invention, the outer case, the use outlet, the waste storage section, the inner case, the rotating squeezing body, the cutter, the filter, the waste outlet, the waste outlet cover, the notch, It goes without saying that the specific structure, shape, position, material, etc. of the discharge gap etc. are not limited to the one embodiment described above, and can be configured and implemented in various ways.

[Effect of idea]

According to the present invention, which has the gist of the structure described in the above-mentioned utility model registration claim, a part of the scum of the cutting material in the inner case can be discharged through the notch or discharge gap provided in the scum outlet cover. When cooking materials with a large amount of fruit juice and soft pulp, this method has the effect of improving the ability to supply the cutting material to the squeezing gap and shortening the squeezing time.
