Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a juicer for collecting fruit juice from fruits, and more specifically, a fruit cutting device for cutting fruits and a juice squeezing device for squeezing juice from cut fruit cuttings. This relates to the structure of the lid to be connected.

[Prior art] A juicer that stores a large amount of fruit juice has a juicer equipped with a storage chamber in the lower part and a centrifugal separation basket in the upper part, and a built-in grating disk to grate the fruit and supply it to the juicer. Usually, one cutting device is horizontally rotatably supported by a support for multiple juicing devices, and fruit is alternately grated and distributed to the multiple juicing devices. .

The cutting device and the juice squeezing device each have separate drive sources, and the two devices are connected by a discharge port at the bottom of the cutting device and a connecting tube provided on the lid of the juice squeezing device.

Since the lid and the connecting cylinder are made of metal, when connecting, the cutting device supported by the support was lifted up and rotated so that its outlet was located directly above the connecting cylinder of the lid of the fixed juice extraction device. It is lowered backward and the discharge port is fitted into the connecting tube. The connection and disconnection of these two devices is performed every time the juice extraction device is switched, and is a tedious manual process.

Furthermore, since the lid is made of aluminum casting and has a flat plate shape, the vibration of the juice extraction device by the centrifugal separation basket rotating at high speed is directly transmitted to the cutting device and generates vibration noise, and sometimes the vibrations generated by both devices are transmitted directly to the cutting device. Sometimes the entire machine moves by creating a resonance phenomenon.

[Problems to be solved by the invention] The present invention has been made to overcome the above-mentioned drawbacks of the conventional juicing machine, and it is possible to easily connect the fruit cutting device and the juice squeezing device, and to make the juice extraction process easier. To provide a lid for a juicing device in which the vibrations of a centrifugal separation basket of the device are not transmitted to a fruit cutting device.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides the above-mentioned conventional juicer in which the lid with a connecting cylinder of the juice extraction device connected to the outlet of the cutting device is made of an elastic material, and the lid is made of an elastic material. A concentric bellows-shaped expansion and contraction means surrounding the connecting tube is provided on the flat surface of the lid.

[Function] The lid of the juice squeezing device is made of an elastic material and has a plurality of concentric bellows-shaped annular grooves surrounding the connecting cylinder, so that the connecting cylinder can freely deform its shape when subjected to external force. At the same time, after being displaced back and forth, left and right, and up and down, it returns to its original shape and position. Therefore, when rotating the cutting device around the support and fitting the cut material discharge port into the connecting tube, there is no need to take the trouble of lifting and lowering the cutting device, and you can just rotate it and align it. Since the connecting tube is deformed or displaced in accordance with the movement of the cutting material discharge port and then restored, the cutting material discharge port can easily fit into the connecting tube. In addition, vibrations due to the rotation of the centrifugal separation cage transmitted to the juice extraction case are absorbed by the bellows-shaped annular groove provided in the lid, and are hardly transmitted to the cutting device.

[Embodiment] A preferred embodiment of the present invention will be described below with reference to the drawings. The fruit cutting device 10 consists of an inverted L-shaped support 14 erected on a machine stand 12 and a cutting case 16 fixed to the tip of the support 14. The support column 14 is horizontally rotatably supported.

The cutting case 16 is a disc-shaped case, and consists of a case body 18 and an opening/closing door covering the front surface of the case body 18, which are connected at the side surface by a hinge mechanism 22 so that the opening/closing door 20 can be opened and closed.

A grating disk 30 having a large number of fine cutting protrusions 28 on its surface is freely rotatably supported in the center of the case body 18, and is rotated by a motor (not shown). In the upper half of the rear side of the opening/closing door 20, there is a fruit supply section 3 with a fruit input port 32 opened at the top.
4 is formed.

An opening 36 is formed on the case body 18 side of the fruit supply section 34, as shown in FIG.
When the opening/closing door 20 is closed to the case body 18,
The opening 36 of the fruit supply section 34 faces the rotating grated disk 30. On the other hand, the lower portions of the case body 18 and the opening/closing door 20 extend downward while being sandwiched, and a rectangular cut material discharge port 38 is formed at the lower end.
is formed.

The juice extraction device 40 includes a juice case 4 that houses a centrifugal separation basket 42 in the upper part and has a juice storage chamber 52 in the lower half.
The motor box 46 is fixedly placed on the machine base 12 and has a built-in motor and a motor box 46 on which the case is placed. The centrifugal cage has a drive shaft 4 vertically supported in the center of a motor box 46 by a housing 50.
It is attached to the tip of 8 and rotates horizontally. The upper end of this juice case 44 is covered with a lid 54. A rectangular connecting cylinder 56 is integrally formed in the center of the lid 54 and is made of an elastic material such as rubber, which is connected to the cut material outlet 38 of the fruit cutting device 10. The lid 54 is provided with several concentric bellows-shaped annular grooves 58 as expansion and contraction means so as to surround the connecting cylinder 56.

The present invention has the above-described structure, and the lid 54 is attached to the juice case 44 of the juicing device 40 as shown in FIGS. 2 and 3, and the fruit cutting device 10 is mounted around the support 14. When the cutting material discharge port 38 and the connecting cylinder 56 of the lid 54 were aligned by horizontal rotation, the cutting material discharge port 38 was easily fitted into the connecting cylinder 56.

In addition, after connecting the cutting outlet 38 and the connecting cylinder 56 of the lid 54, both devices were operated, and an apple was inputted from the input port 32, cut, and squeezed into the juice extraction device. 54, almost no noise is transmitted to the cutting equipment, and the noise is significantly reduced.
The entire machine did not move due to the resonance phenomenon.

[Effects of the invention] As explained above, the lid for the juicing device of the present invention comprises a lid with a connecting cylinder in the center made of an elastic material, and a concentric bellows-shaped annular groove surrounding the connecting cylinder. When the fruit cutting device supported by the support is rotated and its cut material outlet comes into contact with the connecting tube, the connecting tube easily deforms and returns to its original shape after being displaced back and forth, left and right, or up and down. Since it returns to its original position, there is no need to lift and lower the cutting device as in the conventional case, and the cutting material outlet and connecting tube can be easily connected by simply aligning the cutting material outlet and the connecting tube. . In addition, the vibrations caused by the rotation of the centrifugal separation basket of the juice extraction device are absorbed by the bellows formed on the lid, so the large vibrations of the juice extraction device are not transmitted to the fruit cutting device, noise is prevented, and there is no resonance phenomenon. This has many excellent effects, such as preventing accidents in which the connecting cylinder comes off from the cutting material discharge port.
