Description

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

Conventional technology Conventionally, this type of juicer was
It adopts the configuration disclosed in Publication No. 51-25598,
Specifically, it was as shown in Figure 9.

That is, a fixing plate 2 that can freely move left and right on the outer surface of the main body 1 is attached, and the other side of the fixing plate 2 is attached to a protrusion 5 provided on the outer side of the container lid 4 so as to narrowly attach the container 3 placed on the main body 1. The container 3 and container lid 4 were fixed on the main body 1 by hooking them. 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, the container lid 4 is fixed with the fixing plate 2. Then,
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.

However, this time the inventors considered a different form of fixing the container lid and the main body. That is, we devised a structure in which the left and right sides of the container lid are fitted into locking portions that slightly protrude horizontally from the side walls of the main body, and the container can be fixed on the fixing plate by being tightly attached to the container lid.

Problems to be Solved by the Invention However, when the container lid is fixed on the main body with such a structure, no tension force is applied to pull the container lid toward the main body. If there is a small gap between the lids, vibrations may cause chattering noises, and the container and container lid may rattle, so an elastic body is attached to the back of the container, and this elastic body is compressed by the main body. The container and container lid are fixed to the main body while being pressed upwards. However, when an elastic body is provided on the back of the container, foreign matter may adhere to or enter the elastic body itself or between the elastic body and the container during container cleaning, and the elastic body may not function properly. In addition, there was a problem that the elastic body was misaligned and did not operate properly.

Means for Solving the Problems Therefore, in order to solve the above-mentioned problems, the technical means of the present invention is to provide one or more rectangular grooves on the back surface of the container, and to make the width of the grooves larger than the width of the grooves. A rectangular elastic body that is slightly small and does not protrude from the groove is attached.

Effect The effect of this technical means is as follows.
In other words, when the container is mounted on the main body, the elastic body on the back of the container is compressed by a part of the main body, but since the elastic body is in the groove, the elastic body can move up and down reliably without shifting. do. In addition, when separating the container lid from the main body and cleaning it, since the elastic body is slightly smaller than the groove and does not protrude beyond the groove, it is possible to accidentally catch a finger on the end of the elastic body and cause the elastic body to There is no need to remove the elastic body from the container, and since the gap between the elastic body and the container is minute, foreign matter does not enter between the elastic body and the container through this gap and the movement of the elastic body is not obstructed.

Embodiment An embodiment of the present invention will be described above based on the accompanying drawings.

In Figures 1 to 7, 11 is a motor,
It is fixed to the main body 12 via a buffer 13 with screws 14. Reference numeral 15 denotes an output shaft connected to the rotating shaft of the motor 11, and a substantially cylindrical centrifugal separation cage 16 is detachably attached to the upper end of the output shaft. Reference numeral 17 denotes a substantially cylindrical, comb-shaped filter having a plurality of vertical slits, which is detachably attached to the inside of the centrifugal separation basket 16. 18 is a cutter provided at the center bottom of the centrifugal separation basket 16, and 19 is a juice receiving container, with a juice outlet 20 provided in a part of its lower part. Reference numeral 21 denotes a rectangular elastic body provided in the rectangular grooves 22 on the left and right sides of the back surface of the container 19.
When the container 9 is attached, its center portion contacts the protrusion 23 on the upper surface of the main body 12, and when the container 19 is pushed downward, it is compressed. Reference numeral 24 denotes a container lid that is detachably fitted into the container 19 and has a material input port 25 in the center. 26 is a push rod for pressing vegetables, fruits, etc. onto the cutter 18, and 27 is a back plate that covers the lower surface of the main body 12 and has legs 28 attached thereto. 29 is the main body 12
The clamps are provided on the left and right sides of the interior, and are regulated in position by the main body 12 and the back plate 27, leaving a slight play in the vertical direction, and are constantly pressed outward by the spring 30. The clamp 29 is provided with a convex locking part 31 at its upper end and a finger pressing part 32 below the convex locking part 31, both of which protrude to the outside of the main body 12. 33
2 are left and right lid extensions of the container lid 24, and a hole 34 is provided below which is fitted with a convex locking portion 31 of the clamp 29.

Next, the operation of the configuration of this embodiment will be explained. First, when the container lid 24 is attached after mounting everything other than the container lid 24 on the main body 12, the lower end of the lid extension 33 abuts against the convex locking portion 31 at the upper end of the clamp 29. Thereafter, when the container lid 24 is pressed downward, the convex locking portion 31 of the clamp 29 pressed by the spring 30 is displaced inside the main body 12, as shown in FIG. The center portion of the rectangular elastic body 21 contacts the protrusion 23 on the upper surface of the main body 12 . When the container lid 24 is further pressed, the rectangular elastic body 21
is compressed by the protrusion 23 and the convex locking part 31 reaches the position of the hole 34 provided in the lid extension 33. Since the clamp 29 is pressed by the spring 30, the convex locking part 31 closes in the hole 34. and the container 19
and a container lid 24 is fixed on the main body 12.

Here, the rectangular elastic body 21 is the concave groove 2 on the back surface of the container 19.
2 with a slight gap a from the side wall of the groove 22, the side wall of the groove 22 acts as a guide, and it can be moved up and down accurately without causing positional deviation. Also, when the container 19 is removed from the main body 12 for cleaning, the central part of the rectangular elastic body 21 is connected to the concave groove 2.
Since the rectangular elastic body 21 does not protrude beyond the end surface of the groove 22, there is no possibility that the rectangular elastic body 21 will be removed from the groove 22 by accidentally catching the upper surface of the rectangular elastic body 21 with a finger or the like. Further, since the gap a is small, it is difficult for foreign matter to enter the gap b between the rectangular elastic body 21 and the back surface of the container 19, so that the movement of the rectangular elastic body 21 is not inhibited.

Effects of the Invention In the present invention, one or more rectangular grooves are provided on the back surface of the container, and a rectangular elastic body that is slightly smaller than the width of the groove and does not protrude from the groove is attached to the groove. Therefore, the periphery of the groove serves as a guide and the rectangular elastic body is accurately compressed vertically,
The rectangular elastic body is less likely to come off than the groove, foreign matter is less likely to enter the gap between the groove and the rectangular elastic body, and smooth movement of the elastic body can be maintained, which is extremely effective. It goes without saying that, as modifications of the rectangular groove and elastic body, shapes of the groove and the elastic body as shown in FIGS. 8A and 8B are also included within the scope of the present invention.
