Description

[Detailed Description of the Invention] The present invention relates to a fruit juice squeezing machine that improves safety during use and juice squeezing efficiency.

Conventionally, in a fruit juice squeezer that squeezes fruit juice by pressing half-split fruits such as mandarin oranges against a rotating cap-shaped cone, the slag that collects on the filter and closes the through holes formed in the filter is formed in the lower part of the cone. The filter was removed from the through hole to the outer periphery of the filter by a removal piece located close to the filter.

However, when squeezing fruit juice, the fruit is pressed directly against a rotating cone, which is dangerous because fingers may hit the removal piece that rotates close to the filter.

In addition, since the removal piece pushes the dregs against the filter and removes them to the outer periphery of the filter, the dregs are forced into the through-holes, causing the dregs to get mixed into the fruit juice, and at the same time, the through-holes become clogged with dregs, reducing the squeezing efficiency. Something happened.

The present invention has been developed in view of the above points, and aims to provide a fruit juice squeezer with a simple structure that is safe and has good squeezing efficiency.An embodiment of the present invention will be described below with reference to the drawings.

The juice squeezer 1 shown in the figure has a base 2 equipped with a motor etc. inside, a cylindrical container 3 attached to the upper surface of the base 2 by bayonet connection, and a container-shaped container 3 attached to the container by bayonet connection. It consists of a filter 4 and a cap-shaped cone 5 for squeezing fruit juice that rotates at the center of the filter.

An output shaft 6 driven by a motor is projected from the top surface of the base on which the container 4 is mounted, and the output shaft 6 is connected to the container 3.
It is located in a cylindrical insertion hole 7 protruding from the center of the bottom surface.

A normally open switch 9 connected in series with the motor operation switch 8 is mounted inside the base 2.

The switch 9 is opened and closed by a switch operating rod 12 supported in a vertically movable manner in a through hole 11 formed in the side wall of the container 3 to which the handle 10 is attached.

The operating rod 12 is always urged upward by a spring 13, and the downward movement of the operating rod is performed by a return type manual push button 14 mounted on the filter 4.

The push button 14 is attached to a flange 15 stretched over the filter.

The bottom plate 16 of the filter 4 has a large number of radially formed through holes 17 for dropping the squeezed fruit juice into the container 3.

Further, the through hole 17 is formed outside the center of the bottom plate 16 over which the cone 5 is covered.

The bottom plate 16 is formed into an inclined surface with a high center and a low peripheral area.

A cylindrical insertion hole 18 into which the tip of the insertion hole 7L7 is inserted is formed in the center of the bottom plate 16.

Inside the cone 5 is a mounting boss 19 for attaching to the output shaft 6.
The cone 5 is fixed to the output shaft 6 at the boss 19 so as to be non-rotatable with respect to each other.

The cone 5 is mounted so as to cover the insertion hole 18, and its bottom portion is close to the bottom plate 16.

A plurality of protrusions 20 are formed on the circumferential surface of the cone 5 from the apex toward the lower edge, and a plurality of protrusions 20 are formed between the protrusions 20 on the lower circumferential surface of the cone 5. Article 20...
A short protrusion 21 is formed extending in the same direction as .

Further, the upper part of the cone 5 is thin and the lower part is thick.

Therefore, when squeezing small-diameter items such as lemons, it is possible to squeeze them efficiently using the upper part of the cone 5.

Also, when squeezing large-diameter items such as grapefruit, the whole cone 5 is squeezed, and the spacing between the protrusions 20 and 21 is almost the same at the top and bottom of the cone 5.
There is less vibration and efficient aperture can be performed.

At the bottom of the cone 5, downwardly protruding ribs are provided at equal intervals to form air blowing vanes 22.

The wind generated by the blades 22 blows over the bottom plate 16 from the center to the outer periphery as shown by the arrows in FIG.

Therefore, the slag accumulated on the bottom plate 16 is moved to the outer periphery by the wind pressure and is accumulated at that position, so that the slag accumulated on the through hole 17
The fruit juice falls smoothly into the container without being blocked by dregs.

In addition, since the bottom plate 16 has an inclined surface that becomes lower from the center to the outer periphery, the wind pressure that moves the slag is smaller than that of a bottom plate that is horizontally formed, and it is possible to increase the size of the blades or rotate the cone. There is no need to increase the number.

The air blown by the blades 22 is supplied from the inside of the container 3 through the cone boss 19, the insertion hole 18, and the gap between the insertion holes 18 and 7, as shown by arrows in FIG.

Therefore, the pressure inside the container 3 becomes low, and the bottom plate 16 and the through hole 1
Air tries to be sucked into the container 3 through 7...

The fruit juice falling from the cone onto the bottom plate 16 or the fruit juice contained in the dregs is sucked into the container 3 by the air to be sucked in or by the suction force, so that the juice squeezing efficiency can be improved.

As described above, in the present invention, a plurality of protrusions are formed on the circumferential surface of a cap-shaped cone for squeezing fruit juice, and a blower blade that protrudes downward is formed on the bottom of the cone, so that the fruit juice can be squeezed by the lawn. As long as there is no protruding part other than the part where the fruit comes into contact and the fruit is brought into contact with the cone, the cone will not come into direct contact with the hands and fingers, making it safe.

Further, since the dregs accumulated on the filter are moved to the outer periphery of the filter by the wind generated by the blades, the filter does not become clogged and the juice squeezing efficiency does not decrease.

Furthermore, since the air inside the container is sucked out by the blades, the pressure inside the container becomes low, and the air is sucked into the container through the through holes of the filter, and at the same time, the fruit juice is also sucked in, making it possible to squeeze out the fruit juice contained in the dregs. This has great practical effects.
