Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a centrifugal type juicer mainly used in general households.

Conventional configuration and problems thereof Conventionally, in this type of pumper, as shown in FIG. 1, a plurality of locking portions 2 are provided on a container lid 1,
The center of rotation _O1 of the clamp 4 for fixing the container lid 1 to the main body 3 was generally arranged substantially on the same line in the vertical direction.

A downward force is applied to the clamp 4 as indicated by an arrow in the figure by an appropriate biasing device (not shown) such as a spring.

However, this configuration had the following problems. That is, when using the juicer, the lower end opening of the material input cylinder 5 and the centrifugal separation basket 6
Large pieces of the object to be cut or seeds of fruit or the like get into the small gap between the cutter 7 and the cutter 7 fixed to the container lid 1, and a force that tries to lift the container lid 1 upward is sometimes applied. In this case, the total length of the container lid 1 (dimension t in the figure) is realistically 20 to 30 cm.
Because of the long length, the above-mentioned force to lift the container lid 1 upward acts to lift the end surface portion a or b of the container lid 1, and as a result, the end surface portion a or b of the container lid 1 There was a problem in that the product would float and the juice would leak from that part.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a juicer that can prevent juice from leaking from a container lid during use.

Structure of the Invention In order to achieve the above object, the present invention includes a main body with a built-in motor, and a juice receptacle that is placed on the main body and has a cutter and a centrifugal separation cage that is rotationally driven by the motor. a container, and a container lid that closes the upper end opening of the juice receiving container and is provided with a material input cylinder so that the cutter and the lower end opening closely face each other; One end of the clamp that is always attached is rotatably supported, and a locking part is provided on the container lid to which the other end of the clamp is removably locked, and this locking part and the clamp are connected to each other. One end of the clamp is provided at a position offset from the vertical direction. With this configuration, downward force is constantly applied to one end of the clamp, so the locking part of the container lid is As a component of that downward force,
A vertical force and a horizontal force are applied, and among these, the horizontal force exerts a frictional force between the juice receiving container and the container lid, so when the juicer is used, the container The lid is less likely to rise above the juice receiving container, and as a result, juice will no longer leak from the container lid.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Fig. 2 and Fig. 3 a, b,
8 is a main body having legs 10 on a bottom plate 9; 11 is a motor; this motor 11 is attached via a buffer 13 to a support 12 formed within the main body 8 and protruding from the bottom plate 9. Reference numeral 14 denotes a youth container that is placed on the main body 8 and has a youth container 15 inside and a youth outlet 16 at the bottom. A large centrifugal separation basket 17 having a substantially cylindrical shape with a bottom is rotatably arranged.

18 is a cutter fixed to the center bottom of the centrifugal separation cage 17; 19 is a substantially cylindrical filter that is detachably attached to the centrifugal separation cage 17 and has a number of slits 20 in the vertical direction; 21 is the centrifugal separation cage; 1
This is a balancing device of an appropriate type for preventing rotational imbalance vibration of No. 7.

Reference numeral 22 denotes a container lid that fits to close the upper end opening of the juice receiving container 14.
A material input cylinder 23 is provided near the center of the cutter 18, with its lower end opening facing the upper surface of the cutter 18 with a slight gap. This serves as a guide when pressing materials such as vegetables and fruits against the cutter 18.

25 decelerates the rotation of the motor 11 and connects it to the output shaft 26
It is a deceleration device of an appropriate method for transmitting
The output shaft 26 and the centrifugal separation cage 17 are detachably attached to each other by a coupling 27 of an appropriate type. 28 is a cooling fan for the motor 11.

Reference numeral 29 denotes a clamp whose one end is rotatably provided on both side walls of the main body 8. Both clamps 29 are integrally rotated about a point _O2 via a clamp shaft 30. Reference numeral 31 denotes a spring provided on the clamp shaft 30, and the spring 31 constantly applies a downward force F ₁ to one end of the clamp 29.

Reference numeral 32 denotes a locking portion formed on the side of the container lid 22, and the other end of the clamp 29 is removably locked to this locking portion 32. The rotational center O ₂ of the clamp 29 and the locking portion 32 are offset from each other in the vertical direction. Therefore, the downward force F ₁ applied to one end of the clamp 29 by the spring 31 is decomposed into a component force F ₂ in the direction connecting the rotation center O ₂ of the clamp 29 and the locking part 32, and this component force F ₂ acts on the locking portion 32 as it is, and is further decomposed into a vertical component force F ₄ and a horizontal component force F ₅ . Of these, the vertical component force F ₄ acts in the same manner as shown in the conventional example, and the horizontal component force F ₅ pushes the container lid 22 in the horizontal direction, causing a gap between it and the juice receiving container 14. Generates frictional force.

The operation in the above configuration will be explained. First, set each part and turn on switch 33, motor 1
1 rotates, and this rotational force is transferred to the speed reducer 2.
5, is transmitted to the centrifugal cage 17 via the output shaft 26 and the coupling 27, and as a result, the centrifugal cage 17 rotates at high speed.

In this state, when the material is put into the material input cylinder 23 and pressed against the cutter 18 by the push rod 24, the material is finely crushed and scattered in the horizontal direction. And the scattered material goes through filter 1.
9 and is separated into lees and youth by the centrifugal force generated by rotation, only the youth passes through the slit 20, and the passed youth ascends the inner wall surface of the centrifugal separation basket 17. The fuel is discharged from above, and drips out of the machine from the youth outlet 16 provided below the youth receiver 14. On the other hand, the lees cannot pass through the slit 20 and therefore remains inside the filter 19.

During the above series of operations, if the material contains very hard objects such as fruit seeds, or if the cutter 18 is not sufficiently crushing the material and relatively large pieces are generated. , they entered the small gap between the lower end opening of the material input tube 23 and the cutter 18, and the container lid 22
The force that tries to lift the container lid 22 upward is generated, and the force that tries to lift the container lid 22 is:
Both end surfaces c or d of the container lid 22 shown in FIG. 3b
It turns into a force that tries to make it float.

However, in one embodiment of the invention,
Since the lateral force F ₅ is applied to the container lid 22, a frictional force is generated between the container lid 22 and the inner surface of the juice receiving container 14, causing the container lid 22 to lift at least on the c side. This increases the resistance against these forces.

In addition, since only a downward force acts on point d as in the conventional example, it does not improve the lifting of point d, but it can prevent lifting at point c, making it easier to use when compared to the conventional example. The probability of leakage is reduced to about 1/2.

Effects of the Invention As described above, the adjuster of the present invention has one end of the clamp pivotably supported on the main body, and the other end of the clamp provided on the container lid and detachably locked. By arranging the locking part at a position offset from the vertical direction, force is applied to the locking part of the container lid in the horizontal and vertical directions, which reduces the possibility of juice leakage compared to the conventional example. It is possible to reduce the probability to about 1/2.
