Description

[Detailed Description of the Invention] The present invention is equipped with a juice receiver equipped with a stirring device for seasoning and cooling the juice by stirring additives such as honey or ice into the juice squeezed by a centrifugal cage. The present invention relates to a power transmission device in a juicer, etc., and aims to rationally transmit the power of a motor to a stirring device, etc.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is the main body of the juicer, which has legs 3 on a back plate 2.

Reference numeral 4 denotes a motor suspended in the main body 1 so as to be slightly movable vertically and horizontally via a buffer body 5; 6 a container placed on the main body 1 and having a juice receiver 7 and a lees receiver 8 inside; 9 is a bowl-shaped centrifugal separation cage arranged in the juice receiving part 7, which is rotated by a detachably connected motor 4, and the crushed material is separated by a cutter 10 provided at the inner bottom, and the juice is The squeezed lees is discharged to the receiving part 7 and the lees is discharged to the lees receiving part 8, respectively.

Reference numeral 11 denotes a charging tube formed integrally with a container lid 12, which guides fruits, etc. that are pushed to the cutter 10 by a rod 13.

14 is a buckle for fixing the container 6 and the container lid 12 to the main body 1;
Reference numeral 5 denotes a three-sided open recess formed between a pedestal 16 formed integrally with the main body 1 and a part of the container 6, and 17 a recess with a handle 18 that is detachably inserted into the recess 15 and placed on the pedestal 16. Outlet 1 of the container 6 communicating with the juice receiver 7 in the juice receiver
Receive the juice flowing down from 9.

20 is a stirring blade for stirring additives such as honey or ice into the juice to season the juice or to cool the juice; It is arranged.

23 is a power transmission body fixed to the lower end of the shaft 21 and disposed on the outer bottom surface of the juice receiver 17; 24 is a power rotating body that pivotally supports the shaft 25 and is disposed on the pedestal 16; It comes into pressure contact with the power transmission body 23 and transmits power by frictional force.

27 is a rotary pulley fixed to the lower end of the shaft 25 and provided in the pedestal 16; 28 is a drive pulley for the motor 4; 29 is an intermediate pulley that rotates around the shaft 30; It integrally has a small intermediate pulley 32 with a built-in structure.

This intermediate pulley 29 is movably operated by operating means 33 such as a lever protruding from the outside of the main body 1, and presses against and separates from the rotating drive pulley 28, and the small intermediate pulley 5 is moved by frictional force. 32, belt 31, rotating pulley 27
, the power of the motor 4 is transmitted to the stirring blade 20 via the power rotating body 24 and the power transmission body 23.

Subsequently, the drive pulley 28 of the intermediate pulley 29 by means 33
The mechanism for pressing and separating will be explained.

34 is a plate that slides on the mounting plate 35 in the directions of arrows A and B, and a spring 36 is provided at one end of the plate and is pulled in the direction of arrow A by the spring 36.

Further, a cam portion 37 is integrally provided at the other end.

Reference numeral 38 denotes a cut-and-raised portion for rotatably supporting one end of the means 33 with a rivet 39, and is provided integrally with the mounting plate 35.

40 is a convex portion provided on a part of the means 33, and when the means 33 is rotated up and down around the rivet 39, this convex portion 40
slides on the surface of the cam portion 37 to move the sliding plate 34 in the directions of arrows A and B.

In the case of this embodiment, the center of the intermediate pulley 29 is set between the driving pulley 28 and the rotating pulley 27 on or near a straight line passing through the centers of the rotating pulley 27 and the driving pulley 28. When the intermediate pulley 29 is in pressure contact with the drive pulley 28, the belt 31 can be tensioned to the best extent for efficient power transmission, and when the intermediate pulley 29 is separated from the drive pulley 26, the belt 31 is relaxed to prevent aging. Life shortening can be minimized.

Moreover, the length of the belt 31 can be minimized, and the cost of the belt 31 can be made the lowest.

In the above configuration, the juice squeezed out by the centrifugal basket 9 in a conventionally known manner passes through the juice receiving section 7 and then passes through the outlet 1.
9 flows down to the juice receiver 17.

Then, honey is added to the juice accumulated in the juice receptor 17.
Or, explain how to stir in additives such as ice to season or cool the food.

That is, when the motor 4 is rotated and the means 33 is lifted, the sliding plate 34 is pulled in the direction of arrow A by the spring 36, and the intermediate pulley 29 is pressed against the drive pulley 28.

Therefore, the rotational force of the motor 4 is transferred to the drive pulley 28, the intermediate pulley 29 which receives rotational force through friction, and the small intermediate pulley 3.
2. Belt 31. Power rotating body 2 via rotating pulley 27
4 can be conveyed.

The rotational force of the power rotating body 24 is transmitted to the power transmission body 2 by frictional force.
3 to rotate the stirring blades 20.

As a result, the juice is stirred by the stirring blade 20,
It is much faster and easier to mix and stir evenly than when mixing with chopsticks or a spoon.

Next, when stopping the stirring operation described above, the above operation is reversed.

In other words, when the means 33 is pushed down, the convex portion 40 moves into the cam portion 3.
7 surfaces, and the sliding plate 34 is slid in the direction of arrow B.

Then, when the means 33 is pushed down further, the convex portion 40 enters the recess 37a at the bottom of the cam portion 37, and the sliding plate 34 moves as indicated by the arrow B.
It is fixed at the position moved in the direction.

Therefore, the intermediate pulley 29 is separated from the drive pulley 28, the driving force of the motor 4 is not transmitted to the intermediate pulley 29, and the rotation of the stirring blades 20 is stopped, thereby stopping the stirring operation.

As described above, according to the present invention, the length of the belt that transmits power from the intermediate pulley to the rotary pulley can be made as short as possible, and when power transmission to the rotary pulley is not necessary, the belt does not operate and the belt It is possible to prevent deterioration due to aging such as wear of the belt, and when the desired operation is performed only by the drive pulley, there is no unpleasant belt operation noise and it is highly practical.
