Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a filter cleaning brush for removing dregs adhering to a filter in a centrifugal juicer.

A centrifugal juicer houses a centrifugal separator inside the juice tray, rotates it at high speed, and cuts vegetables, fruits, and other materials fed into the separator into small pieces using a cutter installed on the inner bottom of the separator. After cutting, the juice is discharged into the interior of the juice receiver through a filter on the separability peripheral wall, and is further discharged to the outside through a juice outlet.

However, with this type of conventional juicer, each time it is used, it is necessary to remove the lid that blocks the upper opening of the juice tray, remove the centrifugal separation function, wash the filter, etc., and then reassemble it. However, it also has the disadvantage of requiring a lot of time and effort to clean and assemble after use.

Therefore, in recent years, devices have been developed that allow cleaning after use without removing the lid or removing the centrifugal separation capability.

This is because the juice receiver is filled with water and rotates the centrifugal separator to generate a rotating water flow inside the juice receiver, and this rotating water flow removes the dregs and juice attached to the inner surface of the juice receiver to the juice outlet or separately. It is configured to be discharged to the outside through a provided drain port.

However, since it is difficult to remove fine sludge adhering to the filter surface of a centrifugal separator with a rotating water stream, a brush insertion hole is provided in a part of the lid, and the brush is inserted through the insertion hole and brought into contact with the filter surface. It is considered that the lees can be peeled off from the filter surface by rotating the separation capacity.

However, in this case, there is a problem that the dregs peeled off from the filter surface tend to go around and adhere to the bristle part of the brush, which significantly reduces the dregs removal function of the brush.

This idea was created based on these circumstances.
Its purpose is to prevent the dregs peeled off from the filter surface from adhering to the flocked part of the filter cleaning brush that removes dregs adhering to the peripheral wall filter of the centrifugal separation capacity of the centrifugal juicer, thereby achieving excellent dregs removal effect. The aim is to make it sustainable.

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated based on the Example shown in drawing.

The space within the small diameter portion is defined as a juice receiving portion 10.

The lower end of an operating rod 8a introduced into the main body case 3 through the lid 4 is connected to the upper end of the partition wall 8. When the upper end of the operating rod 8a is pulled upward, the partition wall 8 rises. A communication path 11 is formed below the lees tray 9 and the juice tray 10 (Fig. 2).
.

Further, a juice receiver is provided on the peripheral wall of the main body case 3.
A juice outlet 12a communicating with the bottom is provided, and a juice outlet pipe 12 is connected to the outlet 12a from the outside.

A cylindrical boss portion 14 is formed in the bottom plate 13 of the juice receiver portion 10, and a driven shaft 16 is rotatably supported on the boss portion 14 via a bearing 15.

A driven coupling 1 is attached to the lower end of this driven shaft 16.
7 is fixed, and a cylindrical leg portion 1B that surrounds this driven coupling 17 projects from the lower surface of the bottom plate 13.

This leg portion 18 fits into the outer periphery of the cylindrical wall 7 of the base 1 and is placed on the upper surface of the base 1, so that the driven coupling 17 is engaged with the driving coupling 6 in this state. .

Further, a juice receiver is provided at the upper part of the driven shaft 16.
A stirrer blade 19 that also serves as a cutter is attached at the lower position inside.

This stirring blade 19 is connected to a joint 20 screwed onto the upper end of the driven shaft 16.
It is fixed to the shaft 16 by.

Further, a centrifugal separator 21 is detachably attached to the upper end of the driven shaft 16 via a joint 20.

This centrifugal separation capacity 21 is made up of a conical cylindrical filter 22 whose peripheral wall expands upward, and a circular cutter plate 23 with a large number of cutting blades at the bottom.
The filter 22 is made of a thin metal plate provided with a large number of small holes.

The upper end of this filter 22 has a flange 22a projecting outward, which is located at a higher position than the upper end of the partition wall 8, and the squeezed sludge discharged from the centrifugal separator 21 is transferred to the partition wall 8.
The lees receiver is smoothly introduced into the part 9 beyond the upper end of the part 9.

The lid 4 is provided with a material input port 24, and a material input tube 25 is provided projecting from the inner surface of the lid 4 and communicated with the input port 24.

This input cylinder 25 is introduced into the centrifugal separation capacity 21, and its lower end is brought close to the cutter plate 23.

Further, a brush insertion port 26 is provided in the lid 4, and an insertion tube 27 is protruded from the outer surface of the lid 4 and communicates with the insertion port 26.

A cap 28 is rotatably mounted on the insertion tube 27 from the outside, and the inner surface of the cap 28 has a centrifugal separation capacity of 2.
A filter cleaning brush 29 introduced into the filter 1 is connected thereto.

As shown in FIG. 3, the brush insertion tube 27 has oval-shaped locking grooves 30, 30 at mutually symmetrical portions on its outer peripheral surface, and the circumferentially extending portion of each groove 30 is On the upper edge,
A pair of locking protrusions 30a and 30b are formed, and the cap 28 has a pair of locking protrusions 30a and 30b formed at mutually symmetrical portions of the inner peripheral edge, as shown in FIG. Protrusion 31
．． 31.

Further, as shown in FIG. 5, the filter cleaning brush 29 has a flocked part 33 on one end side of the handle part 32, and the side of the flocked part 33 is made of an elastic material (for example, rubber, soft synthetic resin, etc.). tongue pieces 34 are arranged in parallel over the entire length of the flocked part 33, and the other end of the handle part 32 is connected to the cap 28.
is fixed to the inner surface of the

When the user holds the cap 2B and inserts the brush 29 into the brush insertion tube 27, the bristles 33 will be introduced into the centrifugal separator 21.

After fitting the retaining protrusions 31 of the cap 2B into the grooves 30 of the insertion tube 27 and fully inserting the brush 29 into the centrifugal separation capacity 21, the cap 2B is slightly rotated in a certain direction. , each engagement protrusion 31 is connected to one of the locking protrusions 30
a elastically and both locking protrusions 30 a, 30 b
It is kept stable between.

In this state, the flocked portion 33 is oriented in the direction of rotation of the centrifugal separator 21 as shown in FIG. 6a, and is not in contact with the filter 22.

Therefore, when the cap 2B is further rotated in the same direction, each retaining protrusion 31 goes over the other locking protrusion 30b and is stably held between the protrusion 30b and the end of the locking groove 30. The flocked portion 33 and the elastic tongue piece 34 come into contact with the entire area between the upper and lower ends of the inner surface of the filter 22, as shown in FIG.

In the juicer configured as above, in order to make juice using ingredients such as vegetables and fruits, the cap 2
8 to lock the engaging protrusion 31 in the locking protrusion 30 a, 30
The bristles 33 of the brush 29 are spaced apart from the filter 22 as shown in FIG.
is lowered as shown in Fig. 1, and the motor 2 is driven to move the stirring blade 1.
9 and the centrifugal separation unit 21 are rotated, the material is inputted from the input port 24, and is pressed against the cutter plate 23 in the separation unit 21 by a push rod (not shown).

Then, the material is finely cut by the cutting edge of the cutter plate 23, pressed against the filter 22 by centrifugal force, and squeezed while rising along the inner surface of the filter 22.

The juice that has passed through the filter 22 is discharged to the juice receiver section 10, and is discharged to the outside through the juice outlet 12a and the juice outlet pipe 12.

On the other hand, the squeezed lees that has been sufficiently squeezed by the filter 22 passes over the upper opening edge of the filter 22 and is discharged into the lees receiver section 9.

After the juice is made in this way, the inside of the main body case 3 can be cleaned as follows.

That is, by pulling up the operating rod 8a, the partition wall 8 is raised as shown in FIG. 31 is positioned between the locking protrusion 30b and the end of the locking groove 30, and the bristles 33 and elastic tongues 34 of the brush 29 are brought into contact with the inner surface of the filter 22, as shown in FIG.

When the motor 2 is driven, a rotating water flow is generated inside the main body case 3 (inside the juice receiver section 10 and the lees receiver section 9) due to the rotation of the centrifugal separator 22 and the stirring blades 19.

Due to this rotating water flow, the lees in the lees receiver part 9 flow down into the juice receiver part 10 through the communication passage 11, and are discharged to the outside through the juice outlet 12a together with the juice adhering to various places inside the main body case 3. .

At this time, relatively large lees such as thin apple peels may accumulate in the lees receiver part 9, but when such large lees flows down into the juice receiver 10, the stirring blades 1
The juice is finely cut by a cutter formed at 9 and discharged to the outside from the juice outlet 12a.

Furthermore, the lees adhering to the filter 22 are efficiently removed by the flocked portion 33 of the brush 29 and discharged into the lees receiver section 9. Furthermore, the juice receiver flows down to the section 10 through the communication passage 11, and the juice outlet 12a more leaked to the outside.

At this time, the lees once peeled off from the filter 22 may go around and move toward the flocked part 33 again.
Since elastic tongues 34 are arranged side by side along the entire length of the flocked section 33, the lees moving toward the flocked section 33 are peeled off from the filter 22 again by the elastic tongues 34, and are removed from the flocked section 33. The lees receiver is discharged into the part 9 without adhering to the lees.

Therefore, according to the filter cleaning brush, since the tongues made of an elastic material are arranged in parallel over the entire length of the flocked part, the tongues prevent the dregs peeled off from the filter from adhering to the flocked part. The excellent lees removal effect can be sustained.
