Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic cleaning juicer that can be cleaned after use without removing the centrifugal separation function, and particularly relates to an improvement for improving cleaning efficiency.

Generally, a juicer has a juice receiver and a lees receiver in the main body case, and the case accommodates a centrifugal separation function to rotate the juicer at high speed to handle vegetables, fruits, etc. placed in the main case. The material is crushed at the inner bottom of the separation capacity, and the juice part is discharged into the juice receiver through the peripheral wall filter part of the separation capacity, and the lees part is discharged into the inside of the lees receiver from the upper opening edge of the separation capacity. It is configured as follows.

However, with conventional juicers of this type, the lid and centrifugal separation function are removed each time it is used, and the lees container disposes of the lees inside, and the lees and juice that have adhered to various places inside the main body case are removed. This had the disadvantage that it required more time and effort to clean and assemble the juice after use than to make the juice.

Therefore, in recent years, automatic cleaning juicers have been developed that can be cleaned after use without removing the lid, centrifugal separation function, etc.

The lees tray is equipped with a lees discharge port that communicates with the juice tray, and when making juice, the discharge port is closed with a shielding plate, and when washing the juice after making it, the lees discharge port is closed with a shielding plate. Open the plate, fill the main body case with water, rotate the centrifugal separation function, and this rotation causes the lees to flow out to the juice receiver by the rotating water flow generated in the lees receiver.
Furthermore, the device was configured to be discharged to the outside through the juice outlet along with the juice adhering to various places inside the main body case.

However, with this configuration, when making juice, the shielding plate must be closed, and when cleaning, the shielding plate must be opened. If you try to make juice in this condition, the lees inside the lees receiver will mix into the juice.

Therefore, the inventors of the present invention first proposed that the lees receiver automatically open the shielding plate by the rotating water flow generated inside the part, and automatically close the shielding plate when the rotating water flow disappears. The idea was to eliminate the hassle of opening and closing the door.

However, even in this case, a spring or the like is used to prevent the shielding plate from opening due to the wind pressure generated by the rotation of the centrifugal separator or the collision of lees discharged from the separated liquid when making juice. If the holding force is weak, the shielding plate will open when making juice, and if the holding force is too strong, the lees tray will not open only with the rotating water flow inside the part. Since there was a risk, improvement in this point was desired.

This invention was developed based on this situation.When making juice, the shielding plate does not open, and when water is poured into the main body case and the centrifugal separation function is rotated, the shielding plate opens reliably and efficiently. The object of the present invention is to provide a self-cleaning juicer that can perform self-cleaning.

Hereinafter, the configuration of the present invention will be explained based on illustrated embodiments.

It has a coupling 28 that can be attached to and detached from the stirring shaft 21.

A plurality of stirring protrusions 25a are provided at the upper end of the peripheral wall filter portion 26.
are protruded at equal intervals.

Further, from the center of the cutting and raising blade 27, a central blade 29 in the shape of a triangular pyramid or a quadrangular pyramid is projected.

The main body case 2 has an engagement protrusion 30 on the outer surface of the lower part of the foot portion 24, and this protrusion 30 is engaged with an engagement recess 31 provided at the edge of the case mounting base 5 of the juicer base 1. , is set on the case mounting stand 5.

Further, around the centrifugal separation capacity 25, a ring-shaped lees receiver, ie, a lees receiver 32, as shown in FIG.

In this lees container, the container 32 has a flange portion 33 at the upper end of the outer periphery, and the flange portion 33 is locked from above to the stepped portion of the upper large diameter portion of the main body case 2, so that the outer peripheral surface is held horizontally within the case 2. The lees receiver uses a space inside the case 2 below the container 32 as a juice receiver part 34.

In addition, the bottom wall of the container 32 of the lees receiver has a spiral shape that slopes downward in the rotation direction of the centrifugal separator 25, that is, to the left, and there is a vertical step between the highest and lowest parts. 3
5 is formed.

Approximately half of the opening end of the highest part on the outer peripheral wall side is closed by a partition wall 36, and the centrifugal separation capacity 25
There is an appropriate gap between the outer circumference of the upper end and the outer circumference of the upper end.

Further, the opening end at the lowest part is a lees discharge port 37a, which is closed with a shielding plate 37 as shown in FIG.

The shielding plate 37 is designed to open horizontally around the edge on the centrifugal separator 25 side, that is, the lees receiver opens horizontally around a hinge pin 38 provided perpendicularly to the inner circumferential wall of the lowest part of the container 32. Normally, the expansion spring 38a wound around the hinge pin 38 is biased in the closing direction (direction of arrow A in FIG. 2) to close the dregs discharge port 37a.

The shielding plate 37 has a closing portion 37A having the same size as the lees discharge port 37a, and a water receiving portion 37B that extends into the juice receiving portion 34 and extends from the blocking portion 37A.
It is formed larger than the lees discharge port 37a.

A juice outlet 39 is provided in the lower circumferential wall of the main body case 2, and a juice take-out valve 40 is connected to the outer circumferential surface of the case 2 and communicates with the outlet 39.

The take-out valve 40 includes a valve body 41 that communicates with the outlet 39 and opens downward, a cap portion 42 connected to the valve body 41 from the front, and an annular groove 43 on the outer periphery of the valve body. 41 and the cap portion 42 are supported so as to be movable horizontally between the opposing side walls, and the outlet port 39 is supported at the distal end surface between the opposing side walls of the cap portion 41 and the cap portion 42.

It consists of a biased locking member 46 (see FIG. 4) and a compression coil spring 47 that always biases the valve stem 44 in the opening direction (the direction in which the outflow port 39 is opened).

Since the valve stem 44 is normally urged in the opening direction by the spring 47, the take-out valve 40 is in an open state, but when the valve stem 44 is pushed from the outside, the outlet 39 closes, and at the same time the locking member 46 falls into the annular groove 43 by the elasticity of the elastic tongue piece 45, thereby holding the take-out valve 40 in the closed state.

In addition, when opening this take-out valve 40, the locking member 46
When the pressing portion 48 protruding outward from the upper end of the cap portion 42 is pushed, the locking member 46 is disengaged from the annular groove 43 of the valve stem 44, and the valve stem 44 is moved by the spring 47 in the opening direction.

The upper opening of the main body case 2 is closed by a lid body 49.

The lid body 49 is slightly bulged upward and has engaging protrusions 50 at several places on the outer circumference, and these protrusions 5a are engaged with hook parts 51 provided on the outer circumference of the upper end of the main body case 2. It is attached to case 2.

The cylindrical lower end of the lid body 49 fits inside the case 2,
A seal ring 52 is inserted between the lower end and the flange portion 33 of the container 32 to prevent liquid leakage from inside the main body case 2.

Further, a malfunction prevention pawl 53 is protruded from the outer peripheral edge of the lid body 49, and when the lid body 49 is securely attached to the main body case 2, this pawl 53 prevents the operation member 18 from moving into the motor storage portion 3. The switch 17 is held closed by pushing it inward.

The lid body 49 has a material input tube 5 located at a portion slightly offset from the center.
4 are integrally formed.

The material input tube 54 has an upper end protruding toward the upper surface of the lid 49 and a lower end hanging down toward the centrifugal separator 25 to be close to the cutting blade 27 .

Further, a water supply cylinder 55 is protruded from the upper surface of the lid body 49 adjacent to the material input cylinder 54 .

This water supply cylinder 55 communicates with the inside of the main body case 2, and the lid body 4
A pair of upper and lower through holes 56 a and 56 b are formed in the water supply port side wall of the material input cylinder 54 on the lower surface side of the material input tube 9 .

Further, a guide portion 57 located directly below the water supply cylinder 55 is provided protruding from the lower end of the outer peripheral surface of the material input cylinder 54 .

The upper surface of this guide portion 57 is a guide surface 57a that slopes downwardly toward the outside.

A common flange 58 is provided on the outer periphery of the upper end of the material input tube 54 and the water supply tube 55 as shown in FIG.
A locking cap 59 is rotatably mounted on the holder.

A pair of notches 6 are provided at symmetrical positions on the outer circumference of the flange 58.
0, and a pair of locking protrusions 61 are provided at symmetrical positions on the inner circumferential surface of the locking cap 59, and each locking protrusion 61 is aligned with each notch 60 when the locking cap 59 is engaged. A stop cap 59 can be attached to and detached from the flange 58.

Further, an opening 62 is provided in the center of the upper plate of the locking cap 59, and this opening 62 is connected to the material input tube 54 and the water supply tube 55.
It is designed to communicate with

In the figure, 63 is a cleaning tool for cleaning the inside of the main body case 2. This cleaning tool 63 has a brush 66 attached to the tip of a water supply pipe 64 via a link 65, and a flow rate control valve at the base end of the water supply pipe 64. 67 are connected, and the water supply pipe 64 has a T-shaped water supply hole 68 extending from the base end to both sides of the distal end.

Further, a pair of annular grooves 69a and 69b are provided on the outer periphery of the water supply pipe 64 at the same interval as the pair of through holes 56a and 56b provided in the material input tube 54 (however, the upper annular groove 69 a is provided at the connection between the water supply pipe 64 and the control valve 67).

The link 65 has a stopper 70 on its side, and rotatably supports the brush 66 at its tip.

The flow rate control valve 67 has a built-in valve body 71 that can move forward and backward, and is biased toward a valve seat 73 by a compression coil spring 72 to normally close a flow path 74 that communicates between both ends.

The flow control valve 67 is connected to a water faucet via a water supply hose 75, for example.

Therefore, the brush 66 and the link 65 are straightened as shown in FIG.
2a is aligned with the water supply cylinder 55 as shown in FIG. 5, and the brush 66, link 65, and water supply pipe 64 are inserted into the water supply cylinder 55 through the insertion portion 62a.

Then, align one of the annular grooves 69a and 69b provided in the water supply tube 55 with the opening edge of the locking cap 59, and rotate the cap 59 slightly to the right (in the direction of arrow B in FIG. 5). , the locking edge 62 b continuous to the brush insertion portion 62 a enters the annular groove 692 or 69 b to hold the water supply pipe 64 within the water supply port 55 .

When the lower annular groove 69b is locked to the locking edge 62b, the side opening of the water supply hole 68 is aligned with the upper through hole 56a and the back surface of the lid body 49, as shown in FIG. However, when the upper annular groove 89a is locked to the locking edge 62b, the side opening of the water supply hole 68 aligns with the lower through hole 56b as shown in FIG. The tip of the link 65 is pressed against the guide surface 57a of the guide section 57, and the link 65 is bent, and the brush 66 is pushed against the filter section 26 of the centrifugal separation basket 25.
Comes into contact with the inner surface.

When making juice of vegetables, fruits, etc. using the juicer configured as described above, first, the water supply pipe 64 is held in the upper position as shown in FIG.
Open the juice take-out valve 40, place a cup 76 to receive the juice under it, and connect the motor 4.
The material to be made into juice is put into the material input cylinder 54, and the material is pushed into the centrifugal separation basket 25 using a push rod (not shown).
Press it against the inner cutting and raising blade 27.

Then, the material is finely scraped down by the cutting and raising blade 27 rotating at high speed, and the juice is discharged to the juice receiver section 34 through the peripheral wall filter section 26, and flows into the cup 76 from the juice outlet via the take-out valve 40. .

On the other hand, the squeezed lees extracted by the filter section 26 of the centrifugal separation basket 25 passes over the upper opening edge of the separation capacity 25 and is discharged into the container 32.

When making juice, the rotation of the centrifugal separation basket 25 generates a rotating airflow inside the container 32, and wind pressure acts on the closed portion 37A of the shielding plate 37 from the inside, and the lees are blown away by the rotating airflow. However, the wind pressure and the collision of the lees do not cause the shielding plate 37 to open.

After making the juice, the inside of the main body case 2 can be cleaned as follows.

That is, the water supply pipe 64 is held in the lower position as shown in FIG. 1, the brush 66 is pressed against the inner surface of the filter section 26, and the outlet of the juice take-out valve 40 is positioned above the sink.

When water is supplied through the water supply hose 75, the pressure of the water flow causes the valve body 71 of the flow rate control valve 67 to move against the spring 7.
2, the water separates from the valve seat 73 and flows into the water supply hole 68 of the water supply pipe 64.

A part of it passes through the through hole 56b and enters the material input cylinder 54.
The other part is injected into the back side of the lid body 49 to flow into the container 32, and when it overflows from the inner circumferential wall of the container 32, the juice container is The liquid then flows down into the section 34.

Then, when the motor 4 is started, the stirring blades 22 and the centrifugal separation basket 25 rotate at high speed, and the lees receiver receives a rotating water flow mainly from the centrifugal separation basket 25 inside the container 32, and the juice receiver mainly receives the rotating water flow inside the container 34. A rotating water flow is generated by the stirring blades 22.

Therefore, in the case of the lees receiver, the rotating water flow generated in the container 32 pushes the closing part 37A of the shielding plate 37 from the inside, and in the case of the juice receiver, the rotating water flow generated in the part 34 pushes the part 37B of the shielding plate 37 from the inside. Since it is pushed further, the shielding plate 37 is opened against the spring 38H.

Therefore, the lees accumulated in the container 32 is transferred to the container 32.
Due to the rotating water flow generated inside, the juice receiver is swept away into the portion 34 through the lees discharge port 37a.

In this lees, there are the lower end of the material input cylinder 54 and the cutting blade 27.
For example, there may be some particles mixed in that can pass through the gap between the main body case 2, such as the thin peel of an apple. The juice and dregs adhering everywhere inside are discharged to the outside through the juice outlet 39 and the take-out valve 40.

When the cleaning inside the main body case 2 is completed in this way and the water supply and motor 4 are stopped, the rotating water flow disappears and the shielding plate 3
7 is closed by a spring 38a, and the dregs discharge port 37
a is automatically occluded.

Then, when the water supply pipe 64 is locked in the upper position as shown in FIG. 6, all preparations for making juice again are completed.

Therefore, according to this juicer, there is no need to remove the lid body 49, the centrifugal separator 25, etc., and the lees discharge port 37a is automatically opened and closed, so that almost no human operations are required. The inside of the main body case can be automatically cleaned, and juice can be made immediately after cleaning.

The shielding plate 37 that closes the lees discharge port 37a is provided with a water flow receiving part 37B that protrudes into the juice receiving part 34. Since the pressure of the rotating water flow inside the section 34 is also applied, the force for opening the shielding plate 37 during cleaning becomes sufficiently strong, and as a result, the holding force that holds the shielding plate 37 in the closed position becomes strong enough. force (e.g. spring 38a
The shielding plate 37 is used when making juice by increasing the elasticity of the
can be prevented from opening, which prevents malfunctions and enables efficient automatic cleaning.

In the embodiment described above, the height position of the water supply pipe 64 is switched between two levels to bring the brush 66 into contact with or away from the filter section 26 for cleaning or juice production. Brush 6 is not necessary for cleaning.
6 is not required, so if it is not needed, the cleaning tool 63 can be removed and water can be supplied directly into the main body case 2 through the hose 75.

In addition, even if the centrifugal separation capacity 25 only rotates, the juice receiver is
Since it is possible to generate a rotating water flow within the stirring blade 22, the stirring blade 22 is not necessarily required.

Furthermore, in the above embodiment, the shielding plate 37 was designed to open and close the lees tray in the horizontal direction using the hinge pin 38 provided vertically on the inner peripheral wall of the lowest part of the container 32 as a pivot, but as shown in FIG. 7, it opens and closes in the vertical direction. You may also do so.

That is, the shielding plate 77 in FIG. 7 is attached to the bottom surface of the highest end of the container 32 so as to be rotatable in the vertical direction, and the lower end side connected to the closing part 77A protrudes into the juice receiving part 34 to prevent water flow. The receiver has a portion 77B, and a retaining portion 7B that also serves as a weight is provided in the intermediate portion, and is normally in the closed position due to its own weight. It is engaged with a protruding locking protrusion 79.

Therefore, when making juice, the lees discharge port 37a is closed by the shielding plate 77, and the lees receiver does not open due to the rotating airflow generated in the container 32 or the collision of lees components. When water is poured into the main body case 2 and the centrifugal separator 25 is rotated, the shielding plate 77 of the lees receiver is opened by the rotating water flow generated inside and outside the container 32, and the lees receiver is opened to remove the lees in the container 32. The juice receiver flows out to the section 34 through the lees discharge port 37a.

Also in this embodiment, since the juice receiver can utilize the rotating water flow in the portion 34 to open the shielding plate 77, the same effects as in the previous embodiment can be obtained.
