Abstract

The present invention provides a juicer having a fixed cutter and a rotary cutter, which sufficiently grinds the fruit or vegetable fed to the juicer to squeeze as much juice as possible from the ground fruit or vegetable. The rotary cutter is mounted in the strainer basket and fixed on the main shaft of the actuating motor to rotate along the main shaft when starting the motor. The stationary cutter is immovably connected to the lower end of the supply pipe extending downward from the top cover of the juicer to face the upper side of the rotary cutter. A plurality of cutter blades is provided in the inner regions on the lower and upper surfaces of the fixed cutter and the rotary cutter, and grinding zones are provided around the outer peripheral region, respectively. Any fruit or vegetable fed into the juicer via the feed pipe is first ground by the cutter blade between the two cutters, and then the partially ground fruit or vegetable is further ground by scattering into the outer grinding zone by centrifugal force. More juice can be squeezed out before it is released from the juicer.

Description

Juicer with two cutters {JUICER HAVING TWO CUTTERS}

1 illustrates the general structure of a commercially available juicer A. As shown, juicer A is an operating motor A2, which has a base A1, a main shaft A3 with threads externally mounted on the base A1 and projecting upwards therefrom, working A rotary cutter A6 which is sequentially mounted on the upper end of the base A1 surrounding the working bowl A4, the strainer basket A5, and the main shaft A3 of the motor A2, And a top cover A7 covering an upper end of the working bowl A4. Fruits or vegetables are fed into the juicer via a feed tube A8 provided on the top cover A7 and slowly pushed down into a plunger A9. When the fruit or vegetable is pulled out from the lower end of the feed pipe A8, it is ground by the rotary cutter A6 to squeeze juice and pulp. The pulp is scattered directly to the outlet A10 by the centrifugal force of the rotary cutter. Since there is only one rotary cutter, the fruit still contains a considerable amount of juice since the fruit or vegetable is brought into contact with the rotary cutter A6 within a very short time and scattered by centrifugal force. Naturally, this is an unnecessary waste of fruits or vegetables.

Thus, the inventors intend to develop a juicer with two cutters to solve the disadvantage of the conventional juicer with only one rotary cutter.

The main object of the present invention is to provide a juicer with two cutters to sufficiently grind the fruit or vegetable supplied in the juicer to squeeze as much juice as possible.

In order to achieve the above and other objects, the juicer according to the present invention is a rotary cutter mounted on the working motor main shaft of the juicer to rotate along the main shaft of the motor, and a position facing close to the upper side of the rotary cutter And a stationary cutter, movably connected to the lower end of the feed tube, extending downwardly from the top cover of the juicer. A plurality of cutter blades are provided in the inner regions on the lower and upper surfaces of the fixed cutter and the rotary cutter, and grinding zones are provided around the outer peripheral region, respectively. Any fruit or vegetable fed into the juicer via the feed pipe is first ground by the cutter blades between the two cutters, and then the partially ground fruit or vegetable is further ground by scattering into the outer grinding zone by centrifugal force. More juice is squeezed out before it is released from the juicer.

Next, the structures and technical means adopted in the present invention for achieving the above and other objects will be clearly understood from the following detailed description of the preferred embodiments and the accompanying drawings.

2 and 4 are a perspective view and a partial cross-sectional view of the juicer according to the present invention, respectively. As shown, the juicer comprises a base 1 which is mounted upwardly and on which an actuating motor 11 having a main shaft 12 with a thread is mounted. The actuating bowl 13 is connected to the top of the base 1 to form an interior receiving space. A spout is formed on one side of the operation bowl 13. The conical strainer basket 15 is located in the receiving space defined by the working bowl 13 and the base 1 is connected to the main shaft 12 of the actuating motor 11 which projects upward from the center of the bottom of the strainer basket 15. ) Is supported at the center top. Since the structure and position of the components 11, 12, 13, 14, and 15 are generally the same as those of the conventional juicer, they will not be described in detail herein.

Reference is made simultaneously to FIGS. 2, 3 and 4. The juicer includes a rotary cutter 2 and a stationary cutter 3.

The rotary cutter 2 is a round member with a predetermined thickness and is suitable for positioning in the conical filter basket 15 above the main shaft 12. A central portion of the rotary cutter is formed with a recess provided with a threaded hole extending in the axial direction, whereby a fastening means (not shown) passes through the threaded hole in the recess 23 and the rotary cutter (2) can be fixed inside and above the main shaft 12 and the conical strainer basket 15. Thus, the rotary cutter 2 rotates along the main shaft 12 when starting the actuating motor 11. A plurality of first cutter blades 21 are provided in the inner region of the upper surface of the rotary cutter 2 and a first annular grinding zone 22 having a predetermined width is provided around the outer circumferential region.

The fixed cutter 3 is a round member that is thinner than the rotary cutter 2. Since the fixed cutter 3 is formed with an eccentric connecting hole 33 corresponding to the supply pipe 41 extending downward from the top cover 4 of the juicer, the fixed cutter 3 is provided at the lower end of the supply pipe 41. Can be connected. A plurality of second cutter blades 31 are provided in the inner region of the lower surface of the fixed cutter 3, and a second annular grinding zone 32 having a predetermined width is provided around the outer circumferential region.

The top cover 4 is located above and covers the working bowl 13 and the pulp cup 5 located on the base 1 to the other side of the working bowl 13. A feed tube 41 is formed in the top cover 4 and extends downward into the conical strainer basket 15 with the fixed cutter 3 stationarily connected to the lower end of the feed tube.

After the rotary cutter 2 and the conical strainer basket 15 are fixed together to the main shaft 12 in the working bowl 13, the operation of the operating motor 11 causes the rotary cutter 2 to become the main shaft 12. Can rotate with. When the top cover 4 closes the top of the base 1 to cover the working bowl 13 and the pulp cup 5, the rotary cutter 2 and the stationary cutter 3, ie the first cutter blade 21. ) And the second cutter blade 31 as well as the first annular grinding zone 22 and the second annular grinding zone 32 face each other with a certain clearance therebetween.

A large amount of fruit or vegetable is fed into the feed tube 41 and pushed into the working bowl 13 with the plunger 43. When starting the operating motor 11, the rotary cutter 2 rotates but the stationary cutter 3 does not move. At this time, the fruits or vegetables fed downward through the supply pipe 41 are pushed into the gaps between the first and second cutter blades 21 and 31, and thus the first and second cutter blades 21 and 31 are used. The juice is squeezed first. By the centrifugal force of the rotary cutter 2, any ground fruit or vegetable is scattered into the first and second annular grinding zones 22 and 32, which are further ground, so that more juice can be squeezed out. The juice squeezed in this way is filled in the working bowl 13 from the conical filter basket 15 by centrifugal force and flows out of the spout, and the pulp of the ground fruit or vegetable is removed from the filter basket 15 by the centrifugal force. It is scattered to the outlet 42 provided between 4) and the working bowl 13. The pulp cup 5 is located directly below the outlet 42 to collect the pulp discharged.

As mentioned above, the conventional juicer A has only one rotary cutter A6 that does not sufficiently grind the fruit or vegetables supplied to the juicer A before the partially ground fruit or vegetables are scattered and discharged from the working bowl by centrifugal force. Since only a small amount of juice is made from, or squeezed out of, fruits or vegetables. In contrast, the juicer of the present invention further includes a fixed cutter 3 immediately above the rotary cutter 2, and the grinding zone 22 around the outer peripheral area of both the rotary cutter 2 and the fixed cutter 3. , 32). Any fruit or vegetable primarily ground between the rotary cutter 2 and the stationary cutter 3 is scattered into the grinding zones 22 and 32 by centrifugal force to be secondarily ground to squeeze more juice. Also, because the gap between the grinding zones 22 and 32 is small, the partially ground fruit or vegetable can be supported between the two cutters 2 and 3 before being completely ground in the grinding zones 22 and 32. have. Therefore, the grinding zones 22 and 32 can pulverize as much juice as possible by completely grinding the fruits or vegetables supplied to the juicer. Thus, the juicer of the present invention with two cutters is superior to conventional juicers with only one rotary cutter.
