Description

Juicer {Juice extractor}

The present invention relates to a juicer, and more particularly, to a juicer that can improve the convenience and stability of use and the discharge pressure of the residue can be adjusted.

In general, the juicer is a device for pulverizing vegetables, fruits and the like, separating the vegetable juice or fruit juice and fiber. Juicers are also used to grind grains and grind them into flour. In obtaining vegetable juice or fruit juice, juicer is not only excellent in juice rate unlike general mixers and juicers, but also widely used in that it can grind plants with strong fiber that cannot be crushed in mixers or juicers. It is used. For example, the juice of plants such as fresh vinegar contains many rare and useful ingredients for the human body, while the juice contained in fresh vinegar is relatively small and very strong in fiber, so the juice can be squeezed with a general mixer or juicer. Is difficult. However, if you use a juicer can be efficient juice.

The juicer consists of a pair of gears which mesh with each other to rotate, and a juice network surrounding at least a part of the pair of gears as a basic component. Typically, the pair of gears is provided with a helical gear portion meshed with each other, the pulverization is made by the input of the juice material between the helical gear portion. In addition, the juice of the pulverized juice material is discharged to the juice outlet through the juice network, the fiber is discharged through the waste outlet provided on one side of the juice network.

In the juicer, an electric motor is used to rotationally drive the pair of gears. The helical gear portion is formed on the pair of gears, and the juice material passes through the helical gear portion in engagement with the helical gear portion. Therefore, a relatively large motor is used, and a relatively large size or weight of the double gear is preferable in terms of the juice efficiency. However, when the pair of gears increases, handling is not easy, and very powerful thrust is transmitted to each part during operation of the juicer, and thus there is a problem that the assembly state of the parts is loosened. Thus, when the tightening force between the parts is significantly lowered, there is a problem that not only the noise or vibration increases during the operation of the device, but also the normal operation of the device becomes impossible. That is, there is a problem such that a housing or the like surrounding the outer circumference of the twin gear vibrates with respect to the main body.

Another problem is that the residue discharge pressure from the juice network affects the juice efficiency. After the juice is made, the fibrous waste should be discharged through the dregs outlet formed in the juice network. If the waste discharge pressure is too low, the juice efficiency will be reduced, while if the waste discharge pressure is too high, the fibers will stay stagnant in the juice network for too long, causing overloading. There is a possibility. Therefore, the waste discharge pressure should be properly adjusted, but conventionally there was a problem that the waste discharge pressure control means is not provided, or even if it is provided can not maintain the proper pressure.

The present invention is devised to solve the above problems, the object of the present invention is to provide an improved juicer.

Another object of the present invention is to provide a juicer in which the fastening force between the components of the device is stably maintained and the juice efficiency and the ease of juice work are improved.

Another object of the present invention is to provide a juicer in which the residue discharge pressure can be adjusted.

In addition, the juice net cover 15 is covered with an upper portion of the juice net holder 14. The juice net cover 15 is preferably formed entirely of plastic material. When the juice net holder 14 and the juice net cover 15 are coupled to each other, two cylindrical spaces in which a part of the pair of gears 16 may be inserted are formed therein. That is, it has a shape similar to that in which two cylinders are arranged in parallel.

Referring to FIG. 3, the pair gear 16 has a helical gear portion 41 and a screw gear portion 42 formed on one shaft 43. The helical gear portion 41 is rotated in engagement with each other, the juice material is introduced through the input portion 24 in Figure 1 is put between the helical gear portion 41 is subjected to the grinding action. On the other hand, the screw gear 42 is inserted into the space consisting of the juice net holder 14 and the juice net cover 15, the screw is formed to propel the pulverized juice material to the front. The juice material is pressurized by the forward propulsion action of the screw gear portion 42, and thus juice is squeezed out of the pulverized juice material. The juice thus generated may be discharged through the juice network 31 shown in FIG.

In FIG. 2, the portion of the twin gear 16 inserted into the space consisting of the juice net holder 14 and the juice net cover 15 corresponds to the screw gear portion 42.
