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 Conventionally, this type of juicer has been shown, for example, in Japanese Utility Model Publication No. 51-25598 shown in FIG.

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 clamp 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.

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, even if the container lid is not sufficiently fixed on the main body, the switch leading to the motor cannot be activated.
There was a problem in that the motor could not be turned on and the motor would move, which was dangerous from a safety standpoint.

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 locking hole is formed in the lid extension, and a clamp supported by the bottom plate is provided in the main body, and a finger pressing part and a tip are provided in the middle part of the clamp. The main body is provided with a spring that urges the clamp outward, and the main body is provided with a finger push part sliding hole so that the finger A top surface portion of the main body on which the container is placed in the juicer, in which the pushing part is projected, the convex locking part is locked in the locking hole, and the main body and the container lid are connected by the spring. A response switch is provided inside the left and right sides of the body, the two response switches, a main switch, and a motor are connected in series, the container is placed on the upper surface of the body, and the container lid is coupled to the body. It is configured to turn on a response switch.

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

When the container 19 or the container lid 23 is mounted on the main body 12, if either the left or right side of the container lid is not fixed to the main body, the sliding body linked to the response switch provided on the left and right sides of the top surface or the left and right sides of the main body will not move to the specified position. No action is taken. For this reason, the switch that drives the motor cannot be turned on, or even if the main switch is turned on, one of the response switches is turned on.
The motor cannot be turned on and current does not flow to the motor.
The motor is no longer running. In other words, the response switch is ON and current flows to the motor only when the left and right sides of the container lid are completely fixed to the main body.

It is fixed to the support plate 12B fixed to 4. A cross-shaped sliding body is arranged on the top of the response switch 34,
A hole 12-2 is provided in the ceiling of the main body 12, and the upper vertical part 36-1 is inserted into the hole 12-2, which protrudes from the upper surface of the main body 12, and one end of the coil spring 37 is inserted into the horizontal part 36-2 and the upper surface of the response switch 34. It is disposed so as to fit into the vertical portion 36-3, and the horizontal portion 36-2 is pressed against the back surface of the hole 12-2. Response switches 34 built into the main body 12 are provided on the left and right sides of the main body 12 and are normally turned off.
In this state, the response switch 34 is connected in series with the main switch 35 as shown in FIG.

The operation of the configuration of one embodiment of the electric juicer of the present invention will be explained.

After installing everything other than the container lid 23 on the main body 12, the container lid 2 is attached.
3 is attached, the lower end of the extension part 32 clamps 2.
The convex locking portion 30 at the upper end of the clamp 28 receives an inward component force of the main body 12, and the convex locking portion 30 of the clamp 28, which had been pressed outward by the spring 29, is displaced inward of the main body 12. When the container lid 23 is further pushed down and the hole 33 of the lid extension 32 reaches the convex locking portion 30, the clamp 28 is pushed by the spring 29 and is displaced outward, causing the hole 33 to engage the convex locking portion 30. The stopper 30 is fitted and the container lid 23 is fixed to the main body 12. Also, the container lid 23
In the process of attaching the container 19 to the main body 12 while pressing downward, the elastic body 21 provided on the back of the container 19 is compressed by the protrusion 22 on the main body 12 and moved downward, and the lower stage of the back of the container 19 is moved downward. Since the portion 19-2 pushes downward the upper end of the sliding body 36 that protrudes left and right on the upper surface of the main body 12, the lower end of the sliding member 36 pushes the left and right switches 34 provided inside the main body 12.
Turn on. In this state, turn on main switch 35
Then, current flows to the motor 11, causing the motor 11 to rotate. Here, if only one side of the lid extension 32 of the container lid 23 is fixed to the main body 12 and the other is not fixed, the back surface of the container 19 on the side that is not fixed is the elastic body 21 that has been compressed by the protrusion 22 of the main body 12. The container 19 and the container lid 23 are pushed up by the repulsive force of the spring 37 which is pushing up the sliding body 36 pushed by the back surface of the container 19, and the sliding body 36 is also pushed upward. The switch 34 inside the main body 12 is not turned on, but the main switch 35 is turned on.
However, no current flows to the motor 11 and the motor 11 does not move. Next, when separating the container lid 23 fixed to the main body 12 from the main body 12, when the finger pressing part 31 of the clamp 28 is pushed inward of the main body 12 by an external force, the clamp 28 is displaced inward of the main body 12, and a convex shape is formed. When the locking part 30 comes off from the hole 33 of the lid extension part 32, the repulsive force of the elastic body 21 provided on the container 19 and the spring 37
The sliding body 36 pushed up by the container 1
9 rises upwards on the main body 12, and the container lid 23 also rises accordingly, so even if the external force applied to the finger pressing part 31 is removed, the convex locking part 30 will not close to the hole 3 of the lid extension part 32.
3, the container lid 23 can be lifted by hand and separated from the main body 12. In this embodiment, the elastic body 21 is provided on the back surface of the container 19, but the elastic body 21 can be omitted by making the spring 37 a little stronger.

Effects of the Invention The present invention is provided with sliding bodies on the left and right sides of the top surface of the main body or on the left and right sides of the main body, which operate in conjunction with a response switch operated by the container or the container lid. It is possible to prevent the motor from rotating in an incomplete state because the stroke is not sufficient and the response switch cannot be turned on, or even if the main switch is turned on, current does not flow to the motor and the motor does not rotate. This brings about great effects such as the ability to easily attach and detach the container lid.
