Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, in juicers that store lees inside a centrifugal separation basket, rotational vibrations occur due to imbalance of the lees that occurs when extracting lees. As a means to reduce this rotational vibration, as shown in FIGS. 1 and 2, a hollow annular body 2 having an appropriate amount of liquid 1 sealed therein is provided in the centrifugal separation cage 3.
It has been proposed to automatically balance the unbalance of the lees 4 during high-speed rotation of the centrifugal separation basket 3 using the liquid 1.

However, when extracting juices, the material to be cut (fruits, vegetables, etc.) is input from the input port 5, so the rotation speed of the centrifugal separation basket 3 decreases due to the cutting load, and the centrifugal separation basket 3 is centrifuged at a rotation speed of around 1800 rpm as shown in Figure 3. Separation cage 3 was causing abnormal vibrations. In order to prevent this abnormal vibration from being transmitted to the device main body 6, the motor mounting plate 7
It was necessary to provide a vibration isolating rubber 9 with as low hardness as possible between the motor mounting foot 8 and the motor mounting foot 8 provided on the main body 6 of the device. However, if the anti-vibration rubber 9 is made of a material with low hardness, the cutter 10 and the input port tip 11
There is a problem that there is a large gap between the cutting material and the thickness of the workpiece that remains uncut at the end of cutting, which becomes thicker and becomes coarser slag 4, which further leads to a reduction in the reuse rate. Ta.

The present invention provides a juicer in which the coarsening of the dregs caused by the use of the low-hardness anti-vibration rubber has been eliminated.

An embodiment will be described in detail below with reference to the drawings.
In FIGS. 4 and 5, reference numeral 12 denotes a Juicer device body having legs 14 on a bottom plate 13, and 15 is sandwiched between a motor mounting foot 16 and a motor mounting plate 17, which are integrally provided on the bottom plate 13, and has a vibration-proofing effect. Anti-vibration rubber (hardness preferably around 30°), 18 is a motor attached to the motor mounting plate 17,
Reference numeral 19 denotes a youth receptacle that is placed on the main body 12 and has a youth receptacle 20 inside and a youth outlet 21 at the bottom.
Inside, there is a roughly cylindrical centrifugal separation cage (hereinafter referred to as spinner) that can freely rotate and has a larger diameter toward the above.
22 are placed. 23 is the spinner 22
A cutter 24 fixed to the lower surface of the spinner 22 is a substantially cylindrical filter detachably inserted into the spinner 22. The substantially cylindrical filter 24 has a plurality of slits 25 in the axial direction. 26
is a hollow annular body coaxial with the spinner 22 and integrally constructed. The hollow annular body 26 has an appropriate amount of liquid 27 therein, and is further provided with a plurality of slits (not shown) to prevent the liquid 27 from moving rapidly. The spinner 22 is detachably attached to a drive shaft 28 of the motor 18. Further, the spinner 22 is
It is rotated by a drive shaft 28.

Reference numeral 29 denotes a charging cylinder provided on the youth container lid 30, and the inside thereof is hollow. Reference numeral 31 denotes a push rod for pushing the fruits etc. guided into the feeding tube 29 onto the cutter 23, and 32 denotes a motor mounting plate 1.
The motor mounting plate swing regulating rib (hereinafter referred to as "swing regulating rib") provided at
2 is a receiving portion 33 provided on the motor mounting foot 16;
There is a gap t between them.

Further, the tip end portion 34 of the feeding tube 29 regulates the size of the dregs 35 at the end of cutting to a gap with the cutter 23.

Next, the operation of the juicer of the present invention will be explained.

The object to be cut, such as fruit, which is pushed by the push rod 31 to the cutter 23 is crushed by the high speed rotation of the cutter 23, but the spinner 22 is pushed by the push rod 3.
1, the cutter 23 is deflected in the direction of arrow A through the object to be cut, such as fruit, and at this time, the gap between the cutter 23 and the tip 34 of the input cylinder is about to increase. However, since the swing regulating rib 32 of the motor mounting plate 17 contacts the receiving portion 33 (t=0), the swing of the motor mounting plate 17 is restricted, and at the same time, the deflection of the spinner 22 in the direction of arrow A is also restricted. Furthermore, the gap between the cutter 23 and the tip 34 of the feeding cylinder is also regulated, so that the lees 3
5 is prevented from becoming coarse. Next, the lees 35 is applied with centrifugal force by the rotation of the spinner 22, and adheres to the inner surface of the substantially cylindrical filter 24, and the residue is separated. The youth rises up the inner wall surface of the spinner 22 and is discharged from above, and then flows into the youth receiving section 20.
The liquid is dripped to the outside from the youth outlet 21 through the outlet. On the other hand, the dregs 35 of the youth are stored inside the substantially cylindrical filter 24, that is, inside the spinner 22.

At this time, since the fruit is not fed continuously but intermittently, the load applied to the motor 18 also fluctuates, the rotational speed of the spinner 22 changes at a low speed, and the liquid 27 in the hollow annular body 26 also constantly fluctuates. . Further, the liquids 27 collide with each other and abnormal vibrations occur, but since the vibration isolating rubber 15 has low hardness, the amount of vibration transmitted to the motor mounting foot 16 can be reduced. In the embodiment, the swing regulating rib 32 is brought into contact with the receiving part 33, but the same effect can be obtained even if the receiving part 33 is a rib (not shown) planted from the main body 12 or the like.

In this way, the present invention provides the swing regulating rib provided on the motor mounting plate and the receiving part that comes into contact with it, so that the anti-vibration rubber can be made as soft as necessary, and the anti-vibration effect is increased. Even if the lees were softened, coarsening of the lees could be prevented, and the reuse rate could be improved.
