Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic cleaning type juicer that can dispose of dregs and clean it after use without disassembling it, and particularly relates to an improvement for improving cleaning efficiency and cleaning effect.

Generally, a juicer rotates a centrifugal separator at high speed inside the main body case, finely cuts the material to be made into juice on the inner bottom surface of the basket, discharges the juice from the peripheral wall filter part of the basket, and transfers it to the juice outlet. The strained lees is discharged to the outside from the upper opening edge of the basket into a lees tray provided around the upper opening edge.

Therefore, after use, it is necessary to disassemble the lees container, discard the squeezed lees that have accumulated in the lees container, and clean the inside of the main body case before assembling it again. had the disadvantage of requiring a lot of time and effort.

Therefore, in recent years, a self-cleaning juicer has been developed that allows the waste to be disposed of and cleaned after use without being disassembled.

After use, water is poured into the main case, and the basket is rotated to generate a rotating water flow inside the main case.The rotating water flow cleans the inside of the main case, and the lees receiver collects the lees inside the juice container. The juice was discharged to the outside through the juice outlet.

However, in conventional juicers of this type, the lees tray cannot quickly drain out the lees from inside the juicer, resulting in poor cleaning efficiency.

Therefore, the present inventors thought of surrounding the centrifugal separation capacity with a vertically movable cylindrical isolation, forming a juice receiver part on the inside and a lees receiver part on the outside.

In this way, by moving the partition upward, the lower end of the lees receiver can be opened wide all around the entire circumference, and the lees receiver can use this opening as a juice outlet to drain the lees inside the section into juice. The receiver can be quickly drained to the other parts, and cleaning efficiency can be improved.

However, in this case, in order to move the partition up and down by an external operation, for example, an operating member is provided on the top surface of the lid that closes the upper opening of the main body case, and a connecting arm that connects this operating member and the partition is attached to the lid. If it is installed through the connecting arm, the lees discharged from the upper opening edge of the centrifugal separation capacity will scatter diagonally upward and adhere to the connecting arm at a relatively high position. There was a problem in that it became extremely difficult to wash away and a good cleaning effect could not be obtained.

The present invention was developed based on these circumstances, and its purpose is to provide a self-cleaning juicer that automatically disposes of lees and cleans the inside of the case by generating a rotating water flow within the main body case. The aim is to quickly flush out the dregs in the chamber, improve cleaning efficiency, and enhance the cleaning effect.

Hereinafter, the configuration of the present invention will be explained based on embodiments shown in the drawings.

FIGS. 1 and 2 show the usage and cleaning conditions of the juicer, respectively, and the juicer body 3 is detachably mounted on a juicer base 2 in which a motor 1 is installed.

The juicer main body 3 includes a bottomed, substantially cylindrical main body case 7 with a large diameter part 4 at the top, a small diameter part 5 at the bottom, and a tapered part 6 expanding upward in the middle part, and an upper opening of the case 7. It is composed of a removable lid 8 that closes.

A juice outlet 9 is provided in the lower circumferential wall of the small diameter portion 5, and an outlet pipe 10 is connected to the outlet 9.

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 an 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 is provided with three cylindrical bushings 26 at equal intervals around the material input cylinder 21, close to the operation ring 22, and passing through the lid 8.

A cylindrical movable partition wall 27 is housed inside the main body case 7, surrounding the centrifugal separation capacity 15, and is movable up and down.

This movable bulkhead 27 has a lower end bent slightly inward to face 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 juice receptacle leading to the lower part is the part 28, and the annular space outside thereof is the lees receptacle part 29. The juice that has passed through the filter 16 is transferred to the juice receptacle part 28, and the juice is discharged from the upper opening edge of the filter 16. The lees receivers each lead the lees to a section 29.

Further, as shown in FIG. 4, three connecting arms 30 are connected to the upper end of the partition wall 27 at equal intervals.

These connecting arms 30 are bent into a step shape as shown in the figure, and have a lower end connecting portion 3 vertically connected to the upper end of the partition wall 27.
1. An intermediate horizontal portion 32 that extends toward the center of the basket 15 at a position above the centrifugal separation capacity 15, a penetration portion 33 that rises vertically close to the material input tube 21 and slidably penetrates the bush 26, and a lid body. An upper end retaining portion 34 is formed on the upper surface side of the cover 8 to be bent horizontally toward the center of the lid 8 and to fit into each spiral groove 23 of the operating ring 22 .

Therefore, when the operating ring 22 is rotated in a certain direction, the upper end engaging portion 34 slides along the spiral groove 23, and the penetrating portion 33 is guided by the bush 26 and raised.

Then, the partition wall 27 rises via this interlocking arm 30,
An annular phase outlet 3 is provided between the lower end of the partition wall 27 and the tapered portion 6.
5 is formed (see Figure 2).

Further, a flange portion 30 a is provided protruding from the outer periphery of each through portion 33 , and this flange portion 30 a is attached to the bush 26 during normal times.
It is located below.

Reference numeral 36 in FIG. 2 is a cleaning brush for cleaning the inner surface of the filter 16, and this is inserted into the main body case 7 through the water supply tube 24.

In addition, 37 in FIG. 1 is a push rod that is inserted into the material input cylinder 21 and presses the material 38 to be made into juice against the cutting blade 17;
39 indicates a tap 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 39 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 38 to be made into juice is put into the material input tube 21 and pressed against the cutting blade 17 in the centrifugal separator 15 with the push rod 37, the material 38 is transferred to the cutting blade 17 which rotates at high speed.
The juice is cut more finely, and the juice passes through the filter 16 and is discharged to the juice receiver section 28, and flows out from the outflow pipe 10 into the spout 39.

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.

At this time, the squeezed residue discharged from the upper opening edge of the filter 16 scatters diagonally upward, but since the upper half of the connecting arm 30 is located near the center of the centrifugal separation capacity 15,
No lees will adhere to the relatively high position of the connecting arm 30.

Further, a flange portion 30a is provided at a lower position of the bushing 26.
Therefore, the cleaning water inside the main body case 7 will not leak out through the bushing 26.

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

That is, the operating ring 22 is turned in the opposite direction to raise the movable bulkhead 27, forming the phase outflow port 35 below the movable bulkhead 27, positioning the open end of the outflow pipe 10 above the sink, and removing the cap 25. Water is supplied from the water supply cylinder 24 into the main body case 7.

Then, the motor 1 is driven to generate the stirring blade 12 and the centrifugal separation capacity 1.
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 rotation of the stirring blades 12 rises along the tapered portion 6 and reaches the phase outlet opened all around the partition wall 27. From 35 onwards, the lees receiver enters into the part 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, dregs adhering to a relatively low position of the connecting arm 30, such as the lower end connecting portion 31 or the intermediate horizontal portion 32, are also quickly washed away by the rotating water flow generated within the main body case 7.

Incidentally, the lees adhering to the filter 16 are removed by inserting the brush 36 from the water supply tube 24 and bringing it into contact with the inner surface of the filter 16 as shown in FIG. is discharged to.

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.

As described above based on the embodiments, the juicer of the present invention has an operation member (operation ring 2
By rotating 2), the cylindrical partition wall 27 can be moved up and down via the interlocking arm 30, and the axial outlet 35 can be appropriately formed below the partition wall 27. Therefore, by rotating the operating member, Single-motion cleaning can be performed by simply filling water into the main body case 7 and driving the motor 1, and the shaft outlet 35 is formed in a large size below the partition wall 27 over the entire circumference. Therefore, the lees receiver can quickly flush out the lees from within, increasing cleaning efficiency.

In addition, the connecting arm 30 that connects the partition wall 27 and the operating member has an intermediate portion (intermediate horizontal portion 32) bent toward the center of the centrifugal separation capacity 15, and an upper half portion (through portion 33) brought closer to the center of the cage 15. Therefore, the lees discharged from the upper opening edge of the basket 15 will not adhere to the upper half of the connecting arm 30.
Further, the dregs adhering to the lower half of the connecting arm 30 are easily washed away by the rotating water flow generated within the main body case 7, and a good cleaning effect can be obtained.

Furthermore, since the connecting arm 30 is provided with a flange portion 30 a on the outer circumferential portion near the lower surface of the lid body 8, the flange portion 30 a allows the through hole provided in the lid body 8 (through which the connecting arm 30 passes). hole) from the main case 7
The cleaning water inside will not leak out.

Note that the present invention is not limited to the above-mentioned embodiments, and can be modified in various ways.

For example, in the embodiment described above, the cleaning brush 36 was used to clean the filter 16, but even if such a brush is not used, a certain degree of cleaning effect can be obtained using only the rotating water flow.

Further, although the stirring blade 12 that rotates together with the cage 15 is provided below the centrifugal separation capacity 15, this stirring blade 12 is not necessarily required.
