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 cage, and particularly relates to an improvement for improving cleaning efficiency.

In general, a juicer has a juice receiver and a lees receiver in the main body case, and a centrifugal separation basket is housed in the case and rotated at high speed. The materials are crushed at the inner bottom of the separation basket, and the juice is discharged into the juice receiver through the peripheral wall filter section of the separation basket, and the lees is discharged into the lees receiver from the upper opening edge of the separation basket. It is configured as follows.

However, with conventional juicers of this type, the lid and centrifugal separation basket are removed each time the juicer is used, and the lees container discards 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, a self-cleaning juicer has been developed that can be cleaned after use without removing the lid, centrifugal cage, 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, pour water into the main body case, and rotate the centrifugal separation basket. This rotation generates a rotating water flow inside the lees receiver, which causes the lees in the lees receiver to flow out into the juice receiver, and further juice. It was configured to discharge the juice adhering everywhere inside the main body case 2 to the outside through the outlet.

However, if the shielding plate was simply opened by the rotating water stream, there was a risk that the lees flowing out from the lees discharge port into the juice receiver would stay in the juice receiver forever and would not be promptly discharged to the outside. I would like to see an improvement on this point.

The present invention was developed based on these circumstances, and is an automatic cleaning type with a simple structure that can quickly discharge the lees that flowed into the juice tray through the lees discharge port to the outside from the juice outlet. The purpose is to provide a juicer.

FIG. 1 is a sectional view of a self-cleaning juicer, where 1 is a juicer base and 2 is a main body case.

The juicer base 1 has a right half as a tall motor storage part 3 in which the motor 4 is stored, and a left half as a short case mounting base 5, and the four corners of the bottom of the base 1 have a Rubber legs 6 are attached.

The axis of this driven boo 1 river 2 is parallel to the motor shaft 9, and the -
The L end protrudes to the outside through an opening 13 provided in the upper plate of the case platform 5, and a driving coupling 14 is attached to the protruding end.

Both pulleys 11 and 12 are connected by an endless belt 15, and the tension of the bell I/15 can be adjusted by turning an adjustment screw 16 mounted on the mounting plate 7 and horizontally moving the motor 4. There is.

In addition, a normally closed switch 1 is located at the top of the motor housing 3.
7 is installation.

This switch 17 is inserted in series with a starting switch (not shown) for the motor 4, and an operating member 18 for closing the switch 17 is provided on the side plate of the motor housing 3 on the side of the case platform 5. It is made to protrude outward.

The main body case 2 has a middle part tapered upward, and a small diameter cylindrical part below the tapered part has a bottom plate 19 at an intermediate height position. A stirring shaft 21 is rotatably supported via a bearing 20.

Then, a stirring blade 22 that also serves as a cutter is attached to the middle part of the stirring shaft 21, and this is positioned at the inner bottom of the main body case 2. A driven coupling 23 is attached to the lower end of the stirring shaft 21, and this is connected to the cylinder below the bottom plate 19. It is located within the shaped foot portion 24.

Further, a centrifugal separator 25 is detachably attached to the upper end of the stirring shaft 21 at a position above the stirring blades 22.

This separation ability 25 is achieved by positioning a peripheral wall filter part 26 that expands upward in a dome shape at the center of the large diameter part of the upper end of the main body case 2, and having a cut-and-raised blade 27 on the inner bottom surface that extends downward. A coupling 28 that can be attached to and detached from the stirring shaft 21
A plurality of stirring protrusions 25a are protruded at equal intervals from the upper end of the peripheral wall filter portion 26.

Further, from the center of the cutting and raising blade 27, a center blade 29 having a shape of m = square pyramid or square pyramid is projected.

The main body case 2 has an engaging protrusion 30 on the outer surface of the lower part of the foot part 24, and this protrusion 30 is engaged with the four retaining parts 31 provided on the edge of the ace holder 5 of the juicer base 1. , is placed on the case mounting table 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 direction of rotation of the centrifugal separator 25, that is, to the left, and there is a step 35 in the vertical direction between the highest and lowest parts.
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 open end at the lowest part is a lees discharge port 37, which is closed with a shielding plate 38 as shown in FIG.

The upper edge of the shielding plate 38 is rotatably attached to the bottom of the highest part of the container 32, and the upper edge is used as a pivot to open outward, but normally it is attached to the lower edge. The retaining portion 38 a of the lees receiver is engaged with an engaging protrusion 32 a protruding from the bottom surface of the lowest part of the container 32 to close the lees discharge port 37 .

Note that the retaining portion 38a also serves as a weight, so that when the shielding plate 38 is opened, it is closed by the weight of the retaining portion 38a.

Three juice outlet ports are 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 ports 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.
A valve stem 44 that opens and closes, and a valve stem 44 that is inserted through the central opening and installed inside the cap part 42 so as to be able to rise and fall freely, and that is always attached upwardly by an elastic tongue piece 45 that is integrally formed with the valve body 41. 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 50 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 into the centrifugal separation capacity 25 and 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
9, a pair of upper and lower through holes 56a and 56b are bored in the side wall of the material input cylinder 54 on the water supply port side.

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. With each locking protrusion 61 aligned with each notch 60, the locking 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, on the outer periphery of the water supply pipe 64, 1 through hole is provided at the same interval as the pair of through holes 56 a and 56 b provided in the material input tube 54 .
A pair of annular grooves 69 a and 69 b are provided (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 66, and water supply pipe 64 are inserted into the water supply cylinder 55 through the insertion portion 62a.

And annular grooves 69 a , 69 provided in the water supply cylinder 55
When the cap 59 is slightly rotated to the right (in the direction of arrow B in FIG. 5) with either one of the opening edges of the locking gap 59 aligned with the opening edge of the locking gap 59, the locking edge connected to the brush insertion portion 62a The part 62b is the annular groove 69a or 69
b, and the water supply pipe 64 is held 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 69a is locked with the locking edge 62b, the side opening of the water supply hole 68 matches the lower through hole 56b as shown in FIG. The tip of the brush 66 is pressed against the guide surface 57 a of the guide section 57 and the brush 5 is bent, and the brush 66 is pressed against the guide surface 57 a of the guide section 57 .
Comes into contact with the inner surface.

When making juice of vegetables, fruits, etc. using the juicer configured as described above, first, as shown in FIG. Open the valve 40, place a cup 76 or the like to receive the juice under it, start the motor 4, charge the material to be made into juice into the material input cylinder 54, and centrifuge it with a push rod (not shown). Press it against the cutting blade 27 inside the basket 25.

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 separated liquid 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 shielding plate 38 from the inside, and the lees blown away by the rotating airflow. However, due to the wind pressure and the collision of the dregs, the shielding plate 38 cannot be opened.

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.

When the motor 4 is started, the stirring blades 22 and the centrifugal separation basket 25 rotate at high speed, and a rotating water flow is generated inside the main body case 2 due to these rotations.

In the lees receiver, the rotating water flow inside the container 32 pushes the shielding plate 38 from the inside, causing the shielding plate 38 to open outward as shown by the imaginary line in FIG.

Therefore, the lees accumulated in the container 32 is removed from the lees discharge port 3.
7, hits the inner surface of the shielding plate 38 and bounces downward, and the juice receiver is guided to the bottom of the part 34.
It passes through the juice outlet 39 and the take-out valve 40 together with the juice adhering to various parts inside the main body case 2 and is promptly discharged to the outside.

It should be noted that the lees flowing out from the lees discharge port 37 is mixed with things such as thin apple peels that can pass through the gap between the lower end of the material input cylinder 54 and the cutting blade 27. However, such relatively large dregs are finely cut by the blades of the stirring blades 22 and discharged to the outside.

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
8 is closed by its own weight including the engaging portion 38 a, and the engaging portion 38 a is engaged with the engaging protrusion 32 a to open the lees discharge port 37.
occlude.

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

Therefore, according to this juicer, there is no need to remove the lid body 49, the centrifugal separation basket 25, etc., and the lees discharge port 37H 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.

Since the shielding plate 38 that closes the lees discharge port 37 is configured to open outward using the upper edge as a pivot, the lees flowing out from the lees discharge port 37 into the juice receiver 34 is shielded. The juice receiver is guided downward by the plate 38 and is quickly discharged to the outside from the juice outlet 39 provided at the bottom of the part 34, and the simple structure can improve cleaning efficiency. In the above embodiment, the shielding plate 38 is closed by its own weight, but a spring may be provided to hold the shielding plate 38 in the closed position.

However, in this case, the spring does not open the shielding plate 38 due to the wind pressure and the collision of the lees with the rotation of the centrifugal separation basket 25, and the lees receiver does not open the shielding plate 38 until a rotating water flow is generated in the container 32. 38 should be strong enough to open.

Furthermore, in the embodiment described above, the height position of the water supply pipe 64 is switched between two stages to bring the brush 66 into contact with or away from the filter section 26 to perform the cleaning or juice making operation. Brush 6 is not necessary for cleaning.
6 is not required, so if it is not needed, remove the cleaning tool 63 and supply water directly into the main body case 2 with the hose 75.

Furthermore, even if the centrifugal separation capacity 25 is only rotated, the juice receiver is
Since it is possible to generate a rotating water flow within the stirring blade 2
2 is not necessarily necessary either.
