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, the container fixing structure of this type of juicer was
For example, it was as shown in Japanese Utility Model Publication No. 51-25598.

That is, as shown in FIG.
The container 3 and the container lid 4 were fixed on the main body 1 by hooking the upper part of the container 3 placed on the main body 1 onto a protrusion 5 provided on the outside of the container lid 4 so as to tightly fit the container 3 thereon. 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.

By the way, the inventors have considered fixing the container lid and the main body in a different manner. In other words, we considered a structure in which the lid extensions hanging down on the left and right sides of the container lid fit into locking portions that slightly protrude horizontally from the side walls of the main body, and the container could be fixed on the main body by narrowly attaching the container with the container lid. Ta.

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 slight gap between the container and container, there may be problems such as vibrations causing chattering noise or the container or container lid moving loosely.

Means for Solving the Problems The technical means of the present invention for solving the above problems includes: a main body with a built-in motor; a container placed on the main body; and a container covering the top of the container. A lid extension is formed from the container lid and hangs down by fitting into a recess formed on the outer peripheral surface of the container and above the outer periphery of the main body. A clamp is provided, which has a stop part, a finger push part in the middle, and a fulcrum part at the lower end, and is biased outwardly by a spring so that the convex lock part and the finger push part protrude outward. By engaging the convex locking part with the hole of the lid extension, the main body and the container lid are connected with the container in between, and the main body and the container are attached in the direction in which they are separated. An elastic body is interposed therebetween, and the convex locking part of the clamp is engaged with the hole of the lid extension part during the process of elastic deformation of the elastic body. A gap is provided between the lower end of the extension and the lower wall of the recess of the main body.

Effect: According to the above means, the convex locking portion of the clamp and the hole of the lid extension are engaged with each other in a state where the elastic body is elastically deformed. Therefore, the above-mentioned engagement is ensured, and there is no play between the main body, the container, and the container lid, and no chattering noise is generated.

Embodiment An embodiment of the present invention will be described below with reference to the attached FIGS. 1 to 5. In the figure, reference numeral 11 denotes a motor, which is fixed inside the main body 12 via a buffer 13 with screws 14. The motor 11
A substantially cylindrical centrifugal separation cage 16 is removably attached to the upper end of the output shaft 15 connected to the rotating shaft of the centrifugal separation cage 16 . A substantially cylindrical, comb-shaped filter 17 having a plurality of vertical slits is detachably mounted inside the centrifugal separation cage 16. Also, centrifugal separation cage 16
A cutter 18 is fixed to the center bottom of the cutter 18.
A youth container 19 is stacked on top of the main body 12, and a youth outlet 20 is formed in a part of the bottom of the container 19. A groove is formed on the left and right sides of the back surface of the container 19, and an elastic body 21 is provided in this groove. When they make contact and push the container 19 downward, the container 19 is pressed. A container lid 23 is removably fitted into the container 19, and the container lid 23 is made of synthetic resin and has slight elasticity, and is provided with a material input port 24 in the center. A push rod for pressing vegetables and fruits against the cutter 18 is pushed into the material input port 24. The main body 12 has a back plate 26 covering the lower surface and having legs 27 attached thereto. Additionally, clamps 28 are provided on the left and right sides of the inside of the main body 12, and the clamps 28 are regulated in position by the main body 12 and the back plate 26, leaving a slight play in the vertical direction, and are always supported by springs 29.
2. Pressed outward. Further, the clamp 28 is provided with a convex locking portion 30 at its upper end, and is further provided with a finger pressing portion 31 below the convex locking portion 30, and protrudes to the outside of the main body 12. Drooping lid extensions 32 are provided on the left and right sides of the container lid 23, and a hole 33 that fits into the convex locking portion 30 of the clamp 28 is provided in the lower part thereof. Further, after the lower end 34 of the lid extension 32 is fitted into the main body 12, a gap a is created between the lower end 34 and the main body 12.

Next, the operation of the configuration of this embodiment will be explained. When the container lid 23 is first mounted on the main body 12 except for the container lid 23, the lower end 34 of the lid extension 23 abuts against the convex locking portion 30 at the upper end of the clamp 28. Thereafter, when the container lid 23 is pressed downward, the convex locking portion 30 of the clamp 28 pressed by the spring 29 is displaced inside the main body 12, as shown in FIG. It begins to be compressed by the 12 protrusions 22. When the container lid 23 is further pushed and the convex locking portion 30 reaches the position of the hole 33 provided in the lid extension 32, the clamp 28 is pressed by the spring 29, so the convex locking portion 30
0 fits into the hole 33, and the container 19 and container lid 23
is fixed on the main body 12. The back side of the cooling container 19 is pushed upward by the elastic body 21, and the lower side is in contact with the main body 12, while the lower end 34 of the lid extension 32 is pressed against the main body 12 with a gap a remaining.
It is fixed at 2.

Here, in the case of fixing the container lid 23 with the convex locking portion 30 that operates only in the left and right directions where no downward force acts as in this embodiment, the main body 12, the container 19, and the container lid 23 are attached slightly vertically. If rattling occurs, vibrations of the motor 11, etc. may cause a chattering sound between them, or there may be rattling up and down. Attach the container lid 23 to the main body 1.
2, the main body 12, container 19, container lid 2
3 is fixed without wobbling, which prevents chattering noise. Especially when the container 19 is the main body 12
Since there is a gap a between the lower end 34 of the lid extension 32 and the main body 12 when the lid is in contact with the main body 12,
The lower surface of the container 19 can be securely fixed in a state where it is in contact with the lid extension 32.

However, if the lower end of the lid extension 32 comes into contact with the lower surface of the container 19, the elastic force of the elastic body 21 may be weak, or if there is no elastic body 21, the main body 12 and the container 1
A rattling occurs between the lid 9 and the container lid 23, and a chattering sound is generated.

Further, the lower surface of the container 19 is attached to the container lid 2 to the main body 12.
3, the container 19 and the container lid 23 are brought into close contact with each other in the vertical direction, and it is possible to prevent the youth adhering to the inside from leaking to the outside from the fitting portion between the two.

Effects of the Invention As is clear from the description of the above embodiments, the invention includes a main body with a built-in motor, a container placed on the main body, and a container lid that covers the top of the container. A lid extension part is formed that hangs down by fitting into a recess formed on the outer peripheral surface and the upper part of the outer periphery of the main body, while a convex locking part is provided at the upper free end inside the main body.
A clamp is provided which has a finger pushing part in the middle and a fulcrum part at the lower end, and is biased outwardly by a spring so that the convex locking part and the finger pushing part protrude outward. By engaging the locking part with the hole of the lid extension part, the main body and the container lid are combined with the container in between,
An elastic body is interposed between the main body and the container to urge them apart, and in the process of compressing the elastic body, the convex locking part of the clamp engages with the hole of the lid extension. Further, when engaged, a gap is provided between the lower end of the lid extension and the lower wall of the recess of the main body, so that the container lid is fixed in a state where the container is pressed against the main body. containers, container lids,
