Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic cleaning type juicer that can perform lees disposal and cleaning without disassembly, and particularly relates to an improvement for increasing cleaning efficiency with a simple structure.

Generally, a juicer rotates a centrifugal separation basket at high speed inside the main body case, finely cuts the material to be made into juice at the inner bottom of the basket, discharges the juice from the peripheral filter part of the basket, and then sends it to the juice outlet. The strained lees is discharged from the upper opening edge of the basket to a lees receiving portion provided around the upper opening edge of the basket.

Therefore, after use, it is necessary to disassemble it, throw away the squeezed lees that has accumulated in the lees receiver, clean the inside of the main body case, and reassemble it. It 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 gatsu 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 at the same time, the lees in the lees receiving part are collected in a juice container. The juice was then discharged to the outside through the juice outlet.

However, in this case, the lees in the lees receiver will flow out over the peripheral wall of the lees receiver, which requires a large amount of water, and it takes a long time for all the lees in the lees receiver to flow out. The drawback was that the cleaning efficiency was very poor.

In order to eliminate this drawback, an opening for discharging lees is provided on the peripheral wall of the lees receiver, and this opening is normally closed with an opening/closing plate.When cleaning, this opening is opened and the inside of the lees receiver is opened. A conceivable structure is to allow the lees to quickly flow out of the opening, and after washing, close or operate the opening again to prepare for the next use.

However, in this case, there is a hassle of opening and closing the opening/closing plate.
Moreover, if you forget to close the lid after washing, there is a problem that the next time you make juice, lees will get mixed into the juice.

Therefore, the inventors of the present invention mounted the opening/closing plate rotatably, kept it in a closed position at all times with a spring, and created a rotating water flow inside the lees receiving part when cleaning. The idea was to have the opening/closing plate automatically pushed open from the inside by the pressure of the water flow.

In this way, the opening/closing plate can be opened automatically, and the opening/closing plate can be automatically closed due to the disappearance of the rotating water flow, so that the above-mentioned disadvantages can be solved.

By the way, in this case, the rotating water flow generated inside the lees receiver will gather near the outer peripheral wall of the lees receiver due to the action of centrifugal force, so in order to effectively open the opening/closing plate with a small amount of water, it is necessary to It is desirable to attach the plate to the inner circumferential wall of the lees receiver so that it can rotate horizontally.

However, if you do this, there is a risk that if the opening/closing plate opens too far, it may hit the centrifuge cage.
It is also difficult in practice to limit the amount of water supplied so that the opening/closing plate does not open too much.

The present invention was developed based on these circumstances, and its purpose is to provide a lees receiver in an automatic cleaning type juicer in which the lees is discharged by a rotating water flow in an annular lees receiver disposed around a centrifugal separation basket. A lees discharge port is formed in the part, and this discharge port is always closed by an opening/closing plate that is horizontally rotatably supported on the inner circumferential wall of the lees receiving part, and this is opened widely by the rotating water flow to promptly release the lees. The purpose is to allow the dregs to flow out and to prevent the opening and closing plate from hitting the centrifugal separation basket by regulating the maximum opening angle of the opening and closing plate.

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

FIG. 1 shows a juicer, in which a juicer main body 3 is detachably mounted on a juicer base 2 in which a motor 1 is installed.

Further, a guide portion 19 located below the water supply tube 16 is protruded from the lower end of the outer surface of the material input tube 15.
The upper surface of 9 is a guide surface 19 a that slopes downwardly toward the outside.
It becomes.

A pair of engagement recesses 2 are provided at symmetrical positions on the outer circumference of the flange 17.
0, and a locking cap 22 having a pair of locking protrusions 21 at symmetrical positions on the inner peripheral surface is rotatably mounted on the flange 17.

This cap 22 connects each locking protrusion 21 to each locking recess 2.
It can be attached to and detached from the flange 17 in a state where it is aligned with zero.

Further, the upper plate of the cap 22 is provided with an opening having a charging cylinder communication part 22a, a water supply cylinder communication part 22b, and a locking edge 22C, as shown in FIG.

Around the centrifugal separation basket 10, as shown in FIG. 3, a ring-shaped lees receiving container (lees receiving portion) 23 is held horizontally by being held between the main body case 4 and the lid 5. The lower space of this container 23 serves as a juice receiving section 24.

The bottom plate of the lees receiving container 23 has a spiral shape that slopes downward to the left, and the opening formed at the step between the upper and lower ends is the lees discharge port 25, and the lees discharge port 25 is always opened and closed by an opening/closing plate. It is closed at 26.

That is, the opening/closing plate 26 is pivotally attached to the lower end of the inner circumferential wall of the lees receiving container 23 so as to be freely rotatable in the horizontal direction, and is always held in the closed position by a deployment spring 26a wound around the pivot shaft. The lees receiving container 23 is opened by receiving a pressing force from the inside, but the maximum opening angle is regulated by a stopper protrusion 27 protruding from the outer surface of the upper end of the bottom plate of the lees receiving container 23, and the opening/closing plate 26 is opened by the centrifugal separation. It is designed not to come into contact with the basket 10.

Further, a blocking wall 28 is provided to protrude from the upper surface of the bottom plate above the stepped portion.

In the figure, reference numeral 29 is a cleaning tool, and this cleaning tool 29 has a brush 32 attached to the tip of the water supply pipe 30 via a link 31.
The base end of 0 is connected to a water faucet or the like via a hose 33.

Note that the pair of through holes 18a are provided on the outer periphery of the water supply pipe 30.
, 18b, a pair of upper and lower annular grooves 34
a, 34b are provided, and the center hole of the water supply pipe 30 is opened at the lower end of the side surface.

Further, the brush 32 is rotatably supported at the tip of the link 31, and its rotation range is restricted by an L-shaped stopper 35 provided on the nonch 31.

Therefore, when making juice of vegetables, fruits, etc. using this juicer, a cup 36 or the like is placed below the juice outflow pipe 6, and the cleaning tool 29 is pulled up as shown in FIG. 34 b cap 2
2, and the lower end opening of the water supply pipe 30 is aligned with the upper through hole 18a.

Then, the brush 32 separates from the filter 11, comes into contact with the guide surface 19a, and is held in a substantially vertical state.

Therefore, the motor 1 is driven to drive the stirring blades 7 and the centrifugal separation cage 10.
When the material to be made into juice is put into the material input cylinder 15 and pressed against the cutting blade 12 with a push rod (not shown), the material is finely cut by the cutting blade 12 rotating at high speed. The juice passes through the filter 11 and is discharged to the juice receiving part 24, and is then discharged from the outflow pipe 6 to the filter 36.
flows inward.

On the other hand, the squeezed lees squeezed by the filter 11 is
1 and is discharged into the lees receiving container 23.

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

That is, as shown in FIG. 1, the cleaning tool 29 is lowered, the upper annular groove 34a is locked with the locking edge 22C of the cap 22, and the lower end opening of the water supply pipe 30 is aligned with the lower through hole 18b.

Then, the brush 32 comes into contact with the inner surface of the filter 11, so in this state, the open end of the juice outflow pipe 6 is positioned above the sink, and water is supplied into the main body case 4 through the cleaning tool 29.

Then, part of the cleaning water is injected into the material input tube 15 through the through hole 18b to clean the inside of the material input tube 15, and the other part is injected along the inner surface of the lid 5 to clean the inner surface of the lid 5. wash,
It flows down into the lees receiving container 23.

Therefore, the motor 1 is driven to drive the stirring blades 7 and the centrifugal separation cage 10.
When the main body case 4 is rotated at high speed, a rotating water flow is generated inside the main body case 4.

As a result, the opening/closing plate 26 is pushed from inside by the rotating water flow and rotates in the opening direction as shown by the imaginary line in FIG.

However, since the maximum opening angle of the opening/closing plate 26 is regulated by the stopper protrusion 27, there is no possibility that the opening/closing plate 26 will hit the centrifugal cage 10.

Then, the lees in the lees receiving container 23 quickly flows out to the juice receiving part 24 through the lees discharge port 26 which is wide open.
The juice is discharged to the outside from the juice outlet pipe 6.

Incidentally, the lees may contain large particles such as the thin skin of an apple, but such coarse lees are finely cut by the blades formed in the stirring blades 7, so that the lees cannot be removed from the outflow pipe. The lees discharged from 6 does not contain large particles,
Therefore, it can be disposed of directly into the drain, eliminating the hassle of garbage disposal.

Further, the dregs adhering to the inner surface of the filter 11 are removed by the brush 32 and discharged to the outside together with the dregs and juice adhering elsewhere within the main body case 4.

As described above based on the embodiments, the juicer of the present invention has a lees discharge port provided in the annular lees receiving portion (lees receiving container 23), which is always closed by an opening/closing plate. The rotating water flow inside the lees receiver pushes the lees open from the inside and allows the lees to flow out, making it possible to dispose of lees and clean the inside of the main case with a small amount of water.Moreover, the maximum opening angle of the opening/closing plate is regulated by the stopper. Therefore, there is no fear that the opening/closing plate will open too much and hit the centrifuge cage, and the intended purpose can be achieved.

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 stirring blade 7 that rotates together with the centrifugal separation cage 10 is provided, but the stirring blade 7 does not necessarily need to be provided.

Alternatively, a step may be provided on the inner circumferential wall of the lees receiving portion, and a lees discharge port may be formed in the step.
