Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a juicer in which stirring blades in a juice receiving bottle are driven by a fan and whose rotational speed can be adjusted.

A stirring blade is installed inside the juice receiving bottle, and this stirring blade is
Juicers which are driven by a common motor with a centrifugal cage are well known in the art.

However, in conventional juicers of this type, pulleys or gears are attached to the motor shaft and the stirring blade drive shaft, and these are interlocked via a belt or intermediate gear.
In addition to having a complicated configuration, there is a drawback that side pressure acts on the motor shaft, causing the motor to tilt, and the gap between the cutting blade in the centrifugal cage, which is directly connected to the motor shaft, and the material input tube to fluctuate.

Furthermore, in order to be able to adjust the rotational speed of the stirring blades, there is a drawback that a more complicated adjustment means (eg, a speed reducer, a clutch, etc.) must be added.

The present invention was made to eliminate these conventional drawbacks, and its purpose is to provide an extremely simple juicer in which the stirring blades in the juice receiving bottle are driven by the same motor as the centrifugal separation basket. The purpose of this invention is to enable the rotational force of the motor to be transmitted to the stirring blades, without applying lateral pressure to the motor shaft, and to freely adjust the rotational speed of the stirring blades.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a juicer according to the present invention will be explained below based on embodiments shown in the drawings.

FIG. 1 is a sectional view showing a schematic structure of a juicer, in which 1 is a juicer base, 2 is a basket storage container, and 3 is a juice receiving bottle.

A coupling 8 is attached to the upper end of the motor shaft 4a, and a driving fan 9 for air cooling the motor is attached to the lower end of the motor shaft 4a.

A fan case 10 that covers the main drive fan 9 from below is integrally formed on the mounting plate 7.
An intake port 11 is opened in the center of the bottle holder 5, while a coupling shaft 12 is rotatably supported in the center of the bottle mount 5 in parallel to the motor shaft 4a.

A drive coupling 13 is attached to the upper end of the cup link shaft 12, and a driven fan 14 is attached to the lower end of the coaxial shaft 12, and the fan 14 is covered with a fan case 15.

The fan case 15 is provided with an intake port 16 and an exhaust port 17, and the bottom plate of the juicer board 1 is provided with a through hole 18 facing the intake port 16.

Further, an air volume control valve 19 is disposed between the main fan 9 and the driven fan 14.

As shown in FIGS. 2 and 3, this valve 19 has a valve body 23 housed inside a housing 22 having two intake ports 20a, 20b and one exhaust port 21. Three ventilation holes 2 4 a, 2 that communicate internally
4b and 25 are formed.

Further, a stopper pin 26 is provided on the outer periphery of the valve body 23, and a guide groove 27 is provided on the inner periphery of the housing 22, so that they fit together.
The valve body 23 is rotatable relative to the housing 22 within a range in which the stopper pin 26 can move within the guide groove 27.

In the state shown in FIG. 2 in which the valve body 23 is rotated in one direction, one intake port 20a is fully opened in alignment with the ventilation hole 24a.
In the state shown in FIG. 3 in which the other intake port 20b is closed by the valve body 23 and the valve body 23 is rotated in the other direction, one intake port 20a is closed by the valve body 23, and the other intake port 20b is closed by the valve body 23. The opening 20b coincides with the ventilation hole 24b and is fully opened.

The opening areas of both intake ports 20a and 20b when fully open are set to be equal.

When the valve body 23 is in the middle of rotation, that is, the second
In the process from the figure to Fig. 3, which intake port 20a,
20b is also half open, but both intake ports 20a,
It is set so that the sum of the opening areas of the openings 20b is always approximately constant.

The vent hole 25 is always in communication with the exhaust port 21 no matter what rotational position the valve body 23 is in.

A rotary operating shaft 28 is connected to the valve body 23 as shown in FIG. A knob 30 is attached.

Thus, one suction port 20a of the control valve 19 is connected to the exhaust port 17 of the driven fan 14, the other suction port 20b is connected to the through hole 31 raised in the bottom plate of the juicer board 1, and the exhaust port 21 is connected to the duct. The suction port 1 of the active fan 9 via 32
Connected to 1.

The basket storage container 2 is detachably set on the upper surface of the right half of the juicer base 1, and is fixed to the base 1 by a clamp mechanism (not shown) or the like.

A centrifugal separation cage 33 is housed inside the container 2, and the bottom of the separation cage 33 is removably connected to the coupling 8 while the separation cage 33 is housed in the container 2.
This separation basket 33 has a peripheral wall with a mortar-shaped filter part 34, and has a cut-and-raised blade 35 in the shape of a dropper on the inner bottom surface, Materials such as vegetables and fruit are rubbed down with a cutting blade 35, and the juice is discharged from the peripheral wall filter part 34, and the squeezed lees is discharged from the upper opening edge.

On the other hand, inside the basket storage container 2, there is a juice receiving part 36 for receiving the juice discharged through the filter part 34 of the separating basket 33, and a lees receiving part 36 for receiving the squeezed lees discharged from the upper opening edge of the separating basket 33. A receiving portion 31 is provided, and the lees receiving portion 37 extends above the bottle holder 5.

In addition, a juice outflow pipe 38 is provided in the container 2 along the bottom surface of the lees receiving part 37 to allow the juice in the juice receiving part 36 to flow out to the outside. I've let it happen.

In the figure, reference numeral 39 denotes a lid that closes the upper opening of the basket storage container 2, and a material input cylinder 40 that hangs down into the centrifugal separation basket 33 is integrally formed on this lid 39.

The lower end of this input cylinder 40 approaches the cutting blade 35 in the separating basket 33, and supplies the material to be made into juice onto the cutting blade 35.

In the figure, 41 is a blade 3 that cuts and raises the material input into the input cylinder 40.
It is a push rod to push the button to 5.

A stirring blade 42 is attached to the inner bottom of the juice receiving bottle 3.

The shaft 43 of the stirring blade 42 is inserted liquid-tightly through the center of the bottom plate of the bottle 3, and a driven coupling 44 is attached to the lower end.

This driven coupling 44 is connected to the drive coupling 1 when the bottle 3 is placed on the bottle holder 5 in the state shown in FIG.
3, the rotation of the drive coupling 13 is controlled by the stirring blade 42.
It is intended to be communicated to.

In the figure, 45 is a handle protruding from the outer surface of the bottle 3, and 46 is a lid of the bottle 3.

A juice inlet 47 is opened in the bottle lid 46, and the terminal opening of the juice outlet pipe 38 is slightly introduced into the inlet 4T.

In the juicer configured as described above, the juice receiving bottle 3 is placed on the bottle mounting table 5, the motor 4 is started to rotate the centrifugal separation basket 33, and the material to be made into juice is inputted from the material input tube 40. When the material is pressed against the cutting blade 35 with the push rod 41, the material is finely rubbed down by the cutting blade 35, and the juice is discharged through the peripheral wall filter part 34 to the juice receiving part 36, and further to the juice outlet pipe 38. It flows into the bottle 3 through the bottle.

Further, the squeezed lees squeezed in the filter section 34 of the separation basket 33 passes over the upper opening edge of the separation basket 33 and enters the lees receiving section 37.
is discharged to.

On the other hand, the rotation of the motor 4 causes the main drive fan 9 to rotate, and the air in the duct 32 is sucked in through the intake port 11, and further flows through the case of the motor 4 to cool the inside of the motor.

When the operating knob 30 is rotated to position the valve body 23 of the air volume control valve 19 as shown in FIG. 2, a suction air path from the driven fan 14 to the main fan 9 is formed through the control valve 19.

As a result, an air path flowing from the intake port 16 to the exhaust port 17 is formed in the fan case 15, and the driven fan 14 is rotated by the wind pressure of the intake air.
It is transmitted to the stirring blade 42 inside the bottle 3 through 3,440 meshes.

Therefore, the juice flowing into the bottle 3 is stirred by the stirring blades 42.

Also, if sugar or honey is added to the juice,
These are stirred to a uniform concentration.

In addition, the rotation speed of the stirring blade 420 can be adjusted using the knob 3 of the air volume control valve 19.
It can be freely adjusted by rotating 0.

That is, when the knob 30 is turned to gradually rotate the valve body 23 from the position shown in FIG. 2 to the position shown in FIG. As the suction port 20b gradually opens, the amount of air flowing through the fan case 15 of the driven fan 14 gradually decreases, and the rotational speed of the stirring blade 420 decreases, so the stirring blade 420 rotates to the extent that the juice in the bottle 3 does not overflow. The speed can be adjusted appropriately.

Further, when the suction port 20a communicating with the driven fan 14 is closed as shown in FIG. 3, the air volume inside the fan case 15 becomes zero, and the stirring blade 42 can be stopped.

On the other hand, even if the opening area of the suction port 20a changes, both suction ports 2
Since the sum of the opening areas of 0a and 20b is kept almost constant, the air volume within the duct 32 does not change, and therefore a constant amount of cooling air can always be sent into the motor 4.

The above description has been made based on the illustrated embodiments, and according to the juicer of the present invention, the motor 4 that drives the centrifugal separation basket 33
A main fan 9 is attached to the shaft 4a of the main fan 9, and a driven fan 14 and an air volume control valve 19 are provided in the suction air path of the main fan 9, and a driven fan 14 rotated by the wind pressure of the intake air and an air volume control valve 19 are installed. Since the bottle 3 is configured to drive the stirring blade 42 inside the bottle 3, the rotational force of the motor 4 can be transmitted to the stirring blade 42 inside the bottle 3 with an extremely simple configuration without using pulleys, belts, or gears. There is no problem of applying lateral pressure to the motor shaft.

Moreover, since the rotation speed of the stirring blade 420 can be adjusted freely,
The juice in bottle 3 will not overflow.

Note that the present invention can be modified in various ways without being limited to the configurations of the embodiments.

For example, the main drive fan 9 does not need to have a cooling effect for the motor 4, and the suction air volume of the main drive fan 9 does not necessarily have to be constant.

In addition, through holes 18 and 31 for air intake are provided in the bottom plate of the juicer base 1.
If these holes are provided, there is no risk of spilled juice or water being sucked in, but these holes may also be provided in the side plate of the base 1.

In this case, it is preferable to form a protrusion above the through hole to prevent juice, water, etc. from being sucked in.
