Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a juicer equipped with a cleaning tool for cleaning the filter surface of a centrifugal cage without removing it, and particularly relates to an improvement of the cleaning tool.

Juicers are well known in the art that have a configuration in which a centrifugal separation basket is housed in the juicer body, the centrifugal separation basket is rotated at high speed, the material to be made into juice is cut at the inner bottom of the basket, and the juice is discharged through a filter on the peripheral wall of the basket. However, in this type of juicer, squeezed lees tends to adhere to the filter surface of the centrifugal separation basket, so in the past, the centrifugal separation cage was removed from the juicer body and the filter surface was cleaned using a brush or the like. The dregs that had adhered to it were removed.

Therefore, cleaning the filter surface requires a lot of time and is troublesome.

Therefore, it is possible to clean the filter surface by installing a cleaning tool with a brush attached to the tip of the holder and rotating it at high speed inside the juicer body without removing the centrifugal cage and bringing the brush into contact with the filter surface. it was thought.

In this way, since the centrifugal separation cage is rotating at high speed, the filter surface can be quickly cleaned by simply touching the brush to the filter surface, but the entire surface of the brush is applied to the filter surface with uniform pressure. It is difficult to make contact with the filter surface, and there are problems in that the brush comes into local contact with the filter surface, making it impossible to obtain a desired cleaning effect, and that the brush is easily worn out.

Therefore, the purpose of the present invention is to make it possible to obtain a good cleaning effect by making the brush surface of the cleaning tool come into contact with the filter surface with equal pressure, and to extend the life of the brush. To provide a juicer which can be used hygienically by preventing lees from adhering to the juicer.

Further, a cutter-shaped stirring blade 12 is rotatably mounted in the small diameter portion 5 via a bearing 11 provided at the center of the bottom plate.

The stirring blades 12 are connected to a driving coupling 13 on the juicer base 2 side and a driven coupling 1 on the juicer main body 3 side.
The motor 1 rotates through engagement with the motor 4.

Further, inside the main body case 7, a centrifugal separation capacity 15 is housed in a region extending from the large diameter portion 4 to the tapered portion 6.

This basket 15 is formed by cutting and raising a large number of cutting blades 17 on the inner bottom surface of a conical cylindrical filter 16 that expands upward, and is coaxially connected to the stirring blade 12. It rotates together with the stirring blade 12.

The lid body 8 has a slight upward bulge and has engaging protrusions 18 at several locations on the outer periphery, and these protrusions 18 are connected to hook portions 19 provided at the upper end of the outer periphery of the main body case 7. It is attached to the case 7 by being engaged with the case 7.

Note that a seal member 20 is provided between the lid body 8 and the main body case 7.
is inserted.

A material input tube 21 is integrally formed on the lid 8 at a portion slightly offset from the center.

The material input tube 21 has an upper portion protruding toward the upper surface of the lid 8 and a lower end close to the cutting blade 17 within the centrifugal separation capacity 15 .

An operating ring 22 serving as a rotation operating member is rotatably attached to the upper outer periphery of the material input cylinder 21 on the upper surface side of the lid 8.

As shown in FIG. 3, three spiral grooves 23 are formed in the peripheral wall of the operating ring 22 at equal intervals and open downward, inclining in the same direction.

Further, a water supply cylinder 24 that projects diagonally outward from the top surface of the lid 8 is integrally formed at a position on the side of the material input cylinder 21 of the lid 8.
The upper end opening is closed by a cap 25 rotatably attached to the upper surface of the lid body 8.

Furthermore, the lid 8 has three parts around the material input cylinder 21.
Cylindrical portions 26 passing through are provided at equal intervals.

Around the centrifugal separation capacity 15, a flange portion 27 is provided on the outer periphery.
A cylindrical movable partition wall 27 having a diameter a is provided.

This movable partition wall 27 has a lower end facing the tapered part 6 of the main body case 7 and an upper end close to the upper end of the centrifugal separator 15. The outer annular space is the lees receiver part 29,
The juice that has passed through the filter 16 is transferred to the juice receiver section 28.
Furthermore, the lees discharged from the upper opening edge of the filter 16 is guided to the lees receiver section 29, respectively.

Further, an interlocking body 30 as shown in FIG. 4 is attached to the lid body 8.

That is, the interlocking body 30 has three retaining pins 32 inserted into each spiral groove 23 on the inner periphery of an annular flat plate 31 surrounding the material input tube 21, and three cylindrical caps on the upper surface of the flat plate 31. 33 at equal intervals, and each cylindrical cap 33 is placed on each cylindrical portion 26 from above.

Further, a rod-shaped support 34 is suspended from the center of the inner bottom surface of each cylindrical cap 33, and each support 34 is inserted into the cylindrical portion 26.

The lower end of each support body 34 is connected to the flange portion 27a of the movable partition wall 27 at equal intervals.

Therefore, when the operating ring 22 is rotated, the engagement pin 32 slides along the spiral groove 23, and the movable partition wall 2 is moved through the interlocking body 30.
7 is raised and lowered to appropriately form an axial outlet 35 between the lower end of the movable partition wall 27 and the tapered part 6 (second
(see figure).

Reference numeral 36 in FIG. 2 is a cleaning tool used to clean the inside of the juicer body 3, and as shown in FIGS. A brush 40 is housed in an opening 39 provided at the tip of the side surface with a gap formed between the entire periphery of the opening 39, and a substantially central portion of the back plate of the brush 40 is placed at the tip of the holder 38. The plate spring 41 is a connecting member that is connected to the plate spring 41.

The portion of the holder 38 beyond the flange 37 has a rectangular tube shape, and a large number of small holes 42 are provided in the peripheral wall and tip of that portion.

Then, the portion beyond the flange 37 is connected to the water supply tube 24.
Insert the flange 37 into the water supply cylinder 2 with the locking tool 43.
4, and the tip of the holder 38 is brought into contact with the lower end side of the material input cylinder 21 to be held at a fixed position.

Further, the portion outside the flange 37 is cylindrical, and a rubber hose 44 or the like is fitted into that portion to be connected to a water faucet.

The brush 40 has a support pin 4 at the center of the left and right side walls of the back plate.
5, and these pins 45 are inserted into respective elongated holes 46 provided in the left and right side walls of the tip portion of the holder 38 from the inside.

Further, the leaf spring 41 is bent into a U-shape, and the brush 40
The brush 40 is pushed to the side of the holder 38 by pressing the central part of the back plate, and the support pins 45 are normally locked at one end of the elongated hole 46 to project the brush 40 to the side of the holder 38. It can be swung freely.

That is, when an external force is applied to the brush surface, the blan 40 moves inward of the holder 38 against the elasticity of the leaf spring 41, and tilts back and forth about the pin 45 as a fulcrum, as shown by the imaginary line in FIG. As shown by the imaginary lines in FIG. 6, the left and right support pins 45 move non-uniformly within the elongated hole 46 and become tilted left and right.

Therefore, when the flange 37 is locked to the end surface of the water supply cylinder 24 by the locking tool 43 as shown in FIG.
The entire surface of the brush 0 comes into constant contact with the inner surface of the filter 16 with uniform pressure.

Further, a spatula 47 formed of a piece of rubber or the like is attached to the side edge of the opening 39 of the holder 38 by means of adhesive or the like.

In addition, in the figure, 48 is a push rod that is inserted into the material input cylinder 21 and presses the material 49 to be made into juice against the cutting blade 17, and 50
shows a tip that receives the juice flowing out from the outflow pipe 10.

Therefore, when making juice of vegetables, fruits, etc. using this juicer, place the cup 50 below the outflow pipe 10 as shown in FIG.
7 is lowered to close the phase outflow port 35, and the water supply tube 24 is closed with the cap 25, and the motor 1 is driven, the stirring blades 12 and the centrifugal separator 15 rotate at high speed.

Therefore, when the material 49 to be made into juice is put into the material input cylinder 21 and pressed against the cutting blade 17 in the centrifugal separator 15 with the push rod 48, the material 49 is transferred to the cutting blade 17 which rotates at high speed.
The juice portion passes through the filter 16 and is discharged to the juice receiver section 28, and flows out from the outflow pipe 10 into the cup 50.

On the other hand, the squeezed lees squeezed through the filter 16 is filtered through the filter 1.
The lees tray is discharged to the section 29 by passing over the upper opening edge of the container 6.

After making juice in this way, the juicer body 3
The inside can be cleaned as shown in FIG.

That is, the operation ring 22 is turned in the opposite direction to raise the rotating partition wall 27, forming the phase outlet 35 below the movable partition wall 27, positioning the open end of the outflow pipe 10 above the sink, and removing the cap 25. Remove it and insert the cleaning tool 36 into the water supply cylinder 24.

Then, the brush 40 is brought into contact with the inner surface of the filter 16, and the flange 37 is locked to the end surface of the water supply cylinder 24 with the locking tool 43.
Water is supplied into the main body case 7 through the cylinder 38.

Then, cleaning water is sprayed from each small hole 42 of the cylinder 38, and parts that are normally difficult to clean, such as the back surface of the lid 8 and the upper part of the material input tube 21, are efficiently cleaned.

Therefore, by driving the motor 1, the stirring blades 12 and the centrifugal separation capacity 1 are
5 is rotated at high speed, a rotating water flow is generated in the main body case 7, and the rotating water flow generated by the 120 rotations of the stirring blade rises along the tapered portion 6 and reaches the phase outlet ports 35 that are mutually open around the entire circumference.
The lees receiver now enters into the portion 29.

In addition, a rotating water flow is generated inside the lees receiver section 29 due to the rotation of the centrifugal separation capacity 15, so the squeezed lees in the lees receiver section 29 is carried away by the rotating water flow inside the lees receiver section 29 and rotates. Further, the juice receiver quickly flows out into the portion 28 by being drawn by the rotating water flow that enters from below through the phase outlet 35.

Then, it flows down into the small diameter part 5 of the main body case 7 and is discharged to the outside from the juice outlet 9. However, since relatively large lees are finely cut by the blades of the stirring blades 12 in advance, they are passed through the outlet pipe 10. The dregs discharged outside does not contain large particles, and therefore can be disposed of directly into the drain.

Further, the dregs adhering to the inner surface of the filter 16 are scraped up with a spatula 47 and quickly peeled off with a brush 40.
It is discharged to the outside together with the dregs and juice that have adhered everywhere inside the main body case 7.

After the lees disposal and washing are completed in this manner, the operating ring 22 is rotated again to lower the movable partition wall 27 and the phase outlet 35 is closed, so that juice can be produced again.

With the above configuration, the brush 40 of the cleaning tool 37 is swingably connected to the holder 38 by the plate spring 41 as a connecting member, so that the holder 38 is connected to the filter 16 with a centrifugal separation capacity of 15. Even if the brush 40 is not held in parallel, the entire surface of the brush 40 is always in contact with the film surface with substantially uniform pressure, so that a good cleaning effect can be obtained and the life of the brush 40 can be extended.

Note that if the leaf spring 41 is used as a connector for the cleaning tool 37, the holder 38 and the brush 40 can be easily connected.
Although it has the advantage of being easy to clean after use, the connector is not necessarily limited to a leaf spring, and an elastic body such as rubber or a compressed coil spring can also be used.

Further, the contact portion of the holder 38 formed on the material input cylinder 21 and the holder 43 are not necessarily necessary, and the holder 38 may be used by directly holding it.

Further, in the embodiment described above, a stirring blade 12 that rotates integrally with the cage 15 is provided below the centrifugal separation capacity 15, but this stirring blade 12 is not necessarily required.

Since the present invention is as described above, by connecting the brush of the cleaning tool at a substantially central position to the holder of the cleaning tool via an elastic connecting member, the brush can swing freely.
Even if the holder is not held parallel to the filter surface, the entire surface of the brush always comes into contact with the filter surface with approximately equal pressure due to the rocking motion.

Therefore, a good cleaning effect can be obtained, and since the brush does not come into local contact with the filter surface, the life of the brush can be extended.

The holder is cylindrical and serves as a water supply passage during cleaning, and the brush is housed in an opening provided on the side of the tip of the holder with a gap between the entire periphery of this opening. Water passes through the gaps and is ejected from the entire circumference of the brush toward the filter surface.

Therefore, the sludge removed from the filter surface by the brush is prevented from entering the tip of the holder, and the sludge is prevented from adhering to the brush and the connecting member, which makes it hygienic to use and prevents the brush from swinging. There is no fear that it will be disturbed by lees.
