Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric juicer for squeezing juice from vegetables and fruits.

BACKGROUND ART A conventional juicer of this type has a structure as shown in, for example, Japanese Utility Model Publication No. 51-25598 shown in FIG.

That is, a fixing plate 2 that freely moves left and right on the outer surface of the main body 1 is attached, and the other side of the fixing plate 2 is provided on the outer side of the container lid 4 so as to clamp the container 3 placed on the main body 1. The container 3 and container lid 4 were fixed onto the main body 1 by hooking them on the container. The left and right fixing plates 2 are connected by a connecting rod 6 inside the main body 1, and since this connecting rod 6 is pressed downward by a spring 7 inside the main body 1, when the container lid 1 is fixed with the fixing plate 2, The container 3 and the container lid 4 were fixed by receiving a force that brought them into close contact with the main body 1 side.

Problems to be Solved by the Invention However, when the container lid is fixed on the main body with the conventional structure as described above, there is no force that pulls the container lid toward the main body, so that the main body and the container or the container and the container lid are separated. If there is a slight gap between the containers, there are problems such as vibrations causing chattering noises and the containers and container lids rattling.

Means for Solving the Problems The present invention provides a main body with a built-in electric motor, a container placed on the main body, and a container lid that covers the container, and a part of the opposite lower end of the container lid is turned downward. A lid extension is extended, and a downwardly extending annular side plate connected to the lid extension by a connecting portion is integrally formed, and a locking hole is bored in the lid extension, while a locking hole is formed in the main body. A clamp supported by the bottom plate is provided, the clamp has a finger pressing part at the middle part and a convex locking part at the tip part protruding outward and integrally configured, and the main body urges the clamp outward. the main body is provided with a finger-pressing part sliding hole so that the finger-pressing part protrudes;
Furthermore, in the electric juicer in which the convex locking portion locks the locking hole and the main body and the container lid are connected via the container with the spring, a gap between the lid extension of the container lid and the annular side plate is provided. An elastic body is provided at the bottom of the connecting part.

Function The function of the electric juicer of the present invention is as follows.

That is, when the container and the container lid are fixed onto the main body from above, the elastic body located between the container and the gap between the container lid and the outer peripheral plate portion of the container is compressed.
This generates a repulsive force, which presses the container onto the main body and brings it into close contact, eliminating rattling between the container and the container lid, and preventing chattering noise between the container, container lid, and main body due to vibration. can. Further, when separating the container and the container lid, even if the fitting between the two is tight, the repulsive force of the elastic body allows for easy separation.

Reference numeral 25 is a push rod for pressing vegetables, fruits, etc. onto the cutter 18, and reference numeral 26 is a back plate that covers the lower surface of the main body 12 and has legs 27 attached thereto. Clamps 28 are provided on the left and right sides inside the main body 12, and their positions are regulated by the main body 12 and the back plate 26 with a slight play left in the vertical direction. The clamp 28 is provided with a convex locking portion 30 at its upper end and a rectangular groove-shaped finger press portion 31 below the locking portion 30, both of which protrude to the outside of the main body 12. A spring seat plate 12-1 is provided that protrudes downward from the back surface of the ceiling plate of the main body 12, one end of which is inserted into the finger press part 31, and a coiled spring 29 is disposed between the bosses 12-1, so that the clamp 28 is always The main body 1
Press in the direction of the side of 2. 32 constitutes a lid extension by extending a portion of the left and right sides of the container lid 23 into a rectangular shape;
A hole 33 that fits with the convex locking part 30 of the clamp 28 is provided below, and is connected horizontally in parallel with the lid extension 32 inside the root of the substantially rectangular lid extension 32 of the container lid 12. An annular side plate 32-1 that is concentrically integrated with the container lid 12 and connected at the portion 22A and extends downward.
An annular side plate 32-1 is provided at the edge 23A of the groove-shaped recess 23-1 into which the lid extension 32 of the container 19 is inserted.
A partially grooved recess 32- which is held between the lid extension part 32 and the lid extension part 32-

When the container 19 and the container lid 22 are attached to the main body 12, the elastic body 21 is pressed by the outer peripheral upper end surface of the edge 23A of the groove-shaped recess 23-1 of the outer peripheral side plate portion 23 of the container 19.

Next, the operation of the configuration of one embodiment of the present invention will be explained.

First, after installing everything other than the container lid 23 on the main body 12,
When the container lid 23 is attached, the lower end of the lid extension 32 abuts against the convex locking portion 30 at the upper end of the clamp 28. After that, when the container lid 22 is pressed downward, the clamp 28 is pressed by the spring 29 as shown in FIG.
As the convex locking part 30 is displaced inward to the main body 12, the elastic body 21 provided on the container lid 22 begins to be pressed by the outer peripheral end surface of the edge 23A of the container 19. When the container lid 23 is further pressed and the convex locking portion 30 of the clamp 28 reaches the position of the hole 33 provided in the lid extension 32, the convex locking portion 30 will close because the clamp 28 is pressed by the spring 29. The container 19 and the container lid 2 are fitted into the holes 33 and the elastic body 21 is compressed.
2 is fixed on the main body 12.

Here, if there is no elastic body 21, the container 19,
A slight wobble occurs in the container lid 23, the main body 12, and the convex locking part 30 due to variations in vertical dimensions, etc., and chattering noise occurs between them due to vibration of the motor 11 and unbalanced rotation during actual use. However, if the elastic body 21 is present, the repulsive force compressed by the container 19 and the container lid 22 will cause the container 19 to come into close contact with the main body 12, and the container lid 22 will be pressed upward, eliminating rattling and preventing each other from shaking. It is possible to prevent chattering noise from occurring between the two. In addition, the container lid 22 is attached to the container 19.
In the case of separation, the repulsive force of the elastic body 21 allows for easy separation even if the fit between the two is tight.

Effects of the Invention In the present invention, since the container lid is provided with an elastic body that acts in the vertical direction, when the container and container lid are fixed on the main body by engaging the clamp and the container lid, there is a gap between the container and the container lid. As a certain elastic body is compressed and a repulsive force is generated, the container is pressed onto the main body and comes into close contact with the main body, and there is no rattling between the container and the container lid, which eliminates chattering noise between the container, the container lid, and the main body due to vibration. can be prevented from occurring. Further, when separating the container and the container lid, even if the fitting between the two is tight, the repulsive force of the elastic body allows for easy separation.
