Feeding Rod (20)

As shown in Figure 1, in order to easily put the foodstuffs, such as vegetables and fruits into the inlet 301 is used the input rod 20 is empty inside. The input rod 20 is made of an injection rod upper portion 210 and an input rod lower portion 220 formed of plastic, and then bonded by ultrasonic welding. This is not possible to have an empty space inside the normal plastic input rod manufacturing method, the input rod does not have an empty space is a weight enough to the user feel uncomfortable. The input rod upper portion 210 is formed larger than the expansion tube 302 so that the input rod 20 does not fall into the inlet 301. The lower rod 220 is made slightly smaller than the expansion tube 302 of the juicer cover 30 to push the foodstuff into the inlet 301.

An anti-vibration part 221 is formed at one end of a portion where the input rod lower portion 220 and the input rod upper portion 210 come into contact with each other.

The vibration preventing unit 221 is a vibration of the motor (43) generated during the operation of the juicer when the injecting rod 20 is pushed completely into the expansion tube 302 of the juicer cover 30 is the inside of the expansion tube (302) It performs a function of preventing the delivery to the input rod 20. The vibration preventing part 221 is formed in a plurality of long rod shapes. Preferably, the anti-vibration portion is installed four to be symmetrical to the center rod 21 of the injection rod, the cross-section is made of a triangle so that the radius of the end portion 222 is 0.5mm or less to enhance the anti-vibration effect .

Juicer Cover (30)

As shown in FIG. 10, the juicer lid 30 allows the user to look at the juice being extracted from food products such as fruits and vegetables when operating the juicer 10, and the correctness of the parts when disassembling or assembling the juicer. Formed from high-strength translucent or transparent plastic for location identification.

Juicer cover 30, the expansion tube consisting of an upper expansion tube 302a is formed with an inlet 301, which is an empty space for injecting food, and a lower expansion pipe 302b for guiding the food product to the juicer blade 53 safely and accurately. 302, and a juicer cover top plate 303, which is a base surface of the expansion tube 302, a seating surface wall 304 and a right surface wall 305 that start with one end of the juicer cover top plate 303 and fit with the body. , Starting from the center of the circular guide guide fixing plate 307, the juicer cover upper plate 303 for fixing the front wall 306, and the juice guide 60, the left side wall 304 and the right side wall ( 305, each side of the waste discharge wall 308 consisting of four sides sealed in a rectangle extending to the rear 401 of the main body 15, and the guide fixing plate with one side perforated starting from the juicer cover upper plate 303 Straight residue guide continued in series with the residue discharge wall 308 while contacting 307. It consists of the wall 309 and the debris guide wall 310.

The expansion pipe 302 is formed to be eccentric with respect to the center axis of the juicer blade having the same center as the body center axis 402, and is formed vertically with the juicer top plate 303 as an inner wall surface of the oval cylindrical cylinder, The center axis of the expansion tube seen from the front of the juicer coincides with the center axis 312 of the body 15 in which the juicer cover 30 and the body 40 are combined.

The upper expansion pipe 302a protects the user's fingers from touching the sharp juicer blade 53 when the user inputs food products through the inlet 301 or when the juicer 10 is operating, and the rod 20 or a tool capable of pushing the foodstuff is formed in an appropriate length so as not to contact the juicer blade 53. The length is associated with the lower dilation tube 302b described below.

As described above, the cross section of the upper expansion pipe (302a) can be inserted intact in the case of foodstuffs having a relatively small thickness (circular shape), and when the size of the foodstuff is larger than the inlet 301, it can be cut and put in an oval shape. Is formed. In addition, the end of the upper expansion pipe (301a) is formed in a smooth curve so that the user is not sharp even if the hand hits when putting food or transporting the juicer 10 is not injured. Preferably, it is formed so as to have a circular radius of about 0.5mm to about 1.5mm.

As shown in FIG. 2, the upper expansion pipe 302a is formed by forming a lower expansion pipe 302b having the same cross-sectional shape as the upper expansion pipe 302a on the opposite side of the upper expansion pipe 302a of the juicer cover upper plate 303. Connect with When the food is put into the inlet 301, the foodstuff is moved to the lower expansion pipe 302b through the upper expansion pipe 302a of the juicer cover 30, the end 314 being one end of the lower expansion pipe 302b. Meet the juicer blade (53) while maintaining a certain interval at.

The length of the expansion pipe 302, which is the sum of the lengths from the upper end of the upper expansion pipe 302a to the lower end of the lower expansion pipe 302b, serves to protect the safety of the consumer and the juicer blade 53, as mentioned above. However, if the length is too large, it is inconvenient when using the actual juicer, so the length of the expansion tube of the juicer 10 according to the present invention is preferably 102 mm. This length is also suitable for domestic and international standards for products such as juicers or juice extractors.

In the manufacturing method, the toothed blade 531 cannot be formed in the axis center 402 of the juicer blade 53. Therefore, the foodstuff is not cut smoothly at the center of the juicer blade 53 as much as the toothed blade 531 disposed on the outer edge of the juicer blade 53, so that juice extraction is insufficient and the juicer blade 53 of In the central portion is subjected to excessive force by the pressure of the raw food is not cut it is difficult to put the food in the inside of the expansion tube (302). Therefore, as described above, in the present invention, the expansion tube center axis 312 is formed eccentrically about the center axis of the juicer blade 53 having the same center as the body center axis 402, food is uniformly cut and easy It can be put in.

Since the particles of the food product leaked out between the end of the lower expansion pipe 302b and the toothed blade 531 of the juicer blade 53 are not cut by the toothed blade 51 of the juicer blade 53, the lower expanded pipe The end wall 315 of the rotational end point of the motor 43 among the ends of 302b is formed to be parallel to the horizontal plane of the saw blade at a distance of β from the saw blade 531 of the juicer blade 53. . Preferably β is between 1 mm and 2.5 mm. If β is 1 mm or less, when the user inputs food with excessive force, the end of the lower extension pipe 302b may be damaged by colliding with the saw blade 531, and when β is 2.5 mm or more, the particles of the food are not cut. There is a problem that easily flows between the end of the lower expansion pipe (302b) and the juicer blade 53.

Notwithstanding the above technical means, in order to prevent the lower tube end 314 from colliding with the saw blade 531, the following two safety devices are additionally formed.

As shown in FIG. 3, one of the two safety devices is formed by tilting one side 316 of the half of the end of the lower extension pipe 302b mentioned above to have an angle of γ with the plane of the saw blade 531. . Preferably, the angle of γ is about 3 degrees. Therefore, one side 316 of the half surface of the lower end of the expansion tube 302b is gradually increased from 1.5mm from the plane of the saw blade 531 toward the edge from the center axis 312 of the expansion tube.

Another safety device is that the juicer cover top plate 303 is formed from a radially smooth arcuate curved surface having a high mechanical strength from the portion where the lower extension pipe 302b and the upper extension pipe 302a are formed. Therefore, the juicer cover 30 is made of a plastic material having elasticity, and when the inlet 301 is pressed in the direction of the juicer blade 53, the upper plate 303 of the juicer cover is bent, but in the arch structure, the degree of bending is extremely small. do.

The left side wall 304, the right side wall 305, and the front side wall 306 of the juicer lid 30 are formed on a line extending from the outline of the main body 15. The front wall 306, which is a part for joining the juicer cover 30 with the body 15, is a stairway located slightly below the top of the body 15, starting from the outline 317 of the top plate 303 of the juicer cover. It is formed in a curved shape that is smoothly connected to the portion 403. The front wall 306 becomes a wall supporting the upper plate 303 of the juicer cover 30. In addition, the left side wall 304 and the right side wall 305 also serve as a wall for supporting the upper plate 303 of the juicer cover 30 and is coupled to the main body 15.

As shown in FIGS. 1, 3, and 10, the recess 318 for inserting the body clasp 450 into the seat surface wall 304 and the right surface wall 305 in parallel with the main body axis 312. Is formed. The depression 318 is disposed on the same straight line as the outline 405 of the bottom end 404 into which the body clasp 450 of the body 40 is inserted. The recessed portion 318 forms an uneven portion 319 at both sides such that the body 40 and the juicer cover 30 are easily coupled and the juicer cover is not separated from the body 40. The depression 318 is formed at about 2.5 mm from the upper surface of the right surface wall 305 and has the same depression portion 318 and the uneven portion 319 as the right surface wall 305 around the main body center axis 312. The face wall 304 is also formed symmetrically.

The peak 320 into which the hook 451 of the body clasp 450 is fitted in a straight line meeting the juicer cover upper plate 303 at one end of the recess 318 is formed perpendicular to the main body axis 312. . The height of the mountain 320 is slightly larger than the height of the hook 451 to facilitate the hook 451 to the mountain 320 and the width is also slightly larger than the hook 320 to be easily coupled.

The connection bone 322 is formed in the connecting wall 321 from the mountain 320 to the juicer cover upper plate 303 in parallel with the extension tube center axis 312, and is formed slightly larger than the thickness of the hook 451. The mountain 320 and the connection bone 322 are symmetrically formed on the seat wall 304 around the main body axis 312.

Starting from the rear side of the juicer cover 30, the residue discharge wall 308 formed toward the rear side 401 of the main body 15 is connected to the left side wall 304 and the right side wall 305. The waste discharge wall 308 has a smooth curved surface so that the waste discharged from the juice filter 50 can enter the waste container 70. It is hydrodynamically set to reduce the resistance to pressure to a minimum when the dregs are discharged from the juice strainer 50 and to be accurately guided to the dreg barrel 70. The tip of the waste discharge wall 308 is formed only of the curved surface to form a steep cliff on the curved surface to prevent the residue discharged from the juice filter is scattered at the end of the waste discharge wall 308.

In the inside of the waste discharge wall 308, a linear residue guide wall 309 and a curved residue guide wall 310 are formed to complement the function of the residue discharge wall 308. The linear residue guide wall 309 is formed. Is fixed to the juice guide 60, starting from the opposite side of the upper step portion 611 that is one side of the drilled surface of the circular guide guide fixing plate 307, one side is opened to the steep cliff of the waste discharge wall 308 have. The straight residue guide wall 309 forms an angle of about 15 ° from the left side wall 304, which is the same angle as the left discharge wall 61 of the juice guide 60 at the outside of the dregs 70. It is formed inward of the wall 71 to prevent debris from being discharged to the outside of the waste bin 70.

In the same way, the curved residue guide wall 310 is formed on the opposite side of the straight residue guide wall 309 in the structure of the juicer cover. The curved dregs guide wall 310 is formed starting from the cutout 323 of the guide stand fixing plate 307 of the juicer cover 30 to the side 324 of the dregs discharge wall 308.

It is formed by entering the inner wall of the juice guide 60 in the right discharge wall 63 as the wall thickness, and the straight ground guide wall 309 and the angled guide wall wall 310 having an angle of about 30˚ each other is a juice strainer On the 50 side, the width becomes narrower and becomes wider as it proceeds to the dregs 70. The boundary leading from the guide restraint plate 307 fixing the juice guide 60 to the straight residue guide wall 309 and the curved residue guide wall 310 is discharged from the juice filter 50 to the outside of the juicer. Seal to prevent dirt from getting around.

In order to fix the juice guide 60 to the main body 15 and to discharge the dregs discharged from the juice strainer 50 to the dreg barrel 70, the guide fixing plate 307 has a thickness thinner at the end thereof. It is formed in a circular shape formed in the portion facing the waste discharge wall 308 is opened to the straight residue guide wall 309 and the crushed waste guide wall 310 is a passage that is discharged to the waste container (70) .

The guide fixing plate 307 is formed to apply pressure from the top to the bottom of the upper step portion 611 of the juice guide 60 fixed to the main body 15 and the pressure is attached to the main body 15 Generated from the clasp 450 is the main pressure for fixing the juice guide 60 and the juicer cover 30 to the main body 15.

As shown in FIG. 10, the guide fixing plate outer wall 326 is coupled to face the staircase wall 612 of the juice guide 60 and remains empty in a portion where the thickness becomes thinner. The empty space is a shape specially designed to relieve pressure on two opposite surfaces, and has a close relationship with the inner wall 327 to be described later.

The inner wall 327 of the guide fixing plate 307 is formed by entering into the inner wall 613 under the upper step portion 611 of the juice guide 60, that is, the diameter of the circle is small, so the juice filter 50 ) To prevent the juice or bubbles of juice generated in the discharge outlet (64) or discharged to the outside of the juicer (10). Guide guide fixing plate 307 is connected to the lower portion is thinner. An end portion of which the guide guide fixing plate 307 becomes thinner is in contact with the step portion 61 of the juice guide 60.

Juice Guide (60)

Juice guide 60 is a device for guiding the juice and debris separated from the juice filter 50 in the desired direction. The juice guide 60 is a juice discharge path (65) for discharging the juice, juice outlet 651 and the outlet opening and closing device (67), garbage discharge path (614) and garbage discharge port (615) for discharging the residue, the main body ( And a body coupler 66 for coupling to 15).

As shown in FIG. 7, the body coupler 66 is symmetrically left and right with respect to the center axis 67 in order to mount the juice guide 60 to the main body 15 on which the motor 43 is mounted. It is installed.

On the left side 406 and the right side 407 of the main body 15, the lower end portion 41 is formed to couple the juice guide 60, and the body is slightly smaller than the width of the lower end 41. The table 66 extends downward from the lower wall 68 of the juice guide 60 into three walls in the same plane. The width of the body coupler 66 is narrower than the width of the body clasp 450 so that when the juicer 10 is fully assembled, the body coupler 66 is not visible and the length of the body coupler 66 is the juice guide 60. ) Is set so that the lowest point 650 is not in contact with the main body 15, but an end 661 of the body coupler 66 is formed slightly above the juice discharge path 65. An important role of this length is to ensure that vibrations inevitably from the body 40 on which the motor 43 is mounted are not transmitted to the juice guide 60 and the juicer cover 30.

The two walls 663 formed from the outer wall 662 of the body coupler 66 are abutted on both sides 411 and the lower side 412 of the bottom end 41 of the body in a straight line. In addition, the outer wall 662 has a great effect to improve the appearance of the messy appearance of the fruit or vegetable juice as well as giving the appearance of a neat appearance from the consumer.

The bottom wall 68 is circular and closely related to the height and diameter of the juice strainer 60. The lower side of the lower wall 68 is connected to the juice discharge passage 65 and the upper side is connected to the residue discharge passage 614. The upper end of the lower wall 68 has a cross-sectional reduction portion 681 in which the shape of the cross section is changed into a triangle, which is formed equal to the angle ε of the filter net of the juice strainer 50.

The waste discharge path 614, which is a flat circular passage, is formed on the outside from the end face reduction part 681, and the dregs discharged from the juice strainer 50 at the same angle ε as the filter net 54 are applied to the centrifugal force of the juice strainer 50. By hitting the guide holder plate 307 of the juicer cover 30 is discharged to the dregs 70, the debris and guide rod fixing plate 307 that did not reach the guide holder plate 307 in the filter network 54 is bounced off The dregs are collected in the dregs discharge path 614. Due to the direct friction between the vortices and the eaves 511, which are caused by the rotation of the eaves 511, which are repeatedly crossed at the outer edge of the top 51 of the juice filter 50, the dregs fold To be published (617). The upper wall 69 is formed outside the waste discharge path 614. The upper wall 69 is formed from the boundary where the left discharge wall 62 and the waste discharge path 614 meet to the line where the left waste discharge wall 63 is in contact with each other. Formed.

On the upper wall 69, a staircase wall 612 is formed, which is slightly larger in diameter than the upper wall 69, and contacts the guide wall fixing plate outer wall 326 of the juicer cover 30. The upper both side surfaces 618 of the stair wall 612 is formed with a straight portion in contact with the depression 318 of the juicer cover 30, the left left discharge wall 62 and the left right discharge wall 63 proceeds to the rear side. Connected with The left waste discharge wall 62 forms the outer wall of the waste straight guide wall 309 of the juicer cover 30, which extends from the waste discharge plate 617 and extends at an angle of δ from the middle of the height to the outside. , The line connecting the two residue guide walls 309 and 310 of the juicer cover 30 and the guide guide plate 307 and the step wall 612 and the residue discharge wall 308 of the juice guide 60 are slightly connected. It is combined with a gap of, in order to exclude the possibility that the user may miss even if the user does not combine correctly. Juicer 10 according to the present invention is set to the angle of δ to about 15 degrees. The waste discharge plate 617 is integrated from the waste discharge passage 614 toward the waste waste container 70, but the end 619 is higher than the waste waste container 70 so that there is no inconvenience when putting or removing the waste waste container 70. .

The juice separated from the juice strainer 50 collides with the lower wall 68 through the micropores 541 of the filter net 54 to be collected at the juice outlet 651. The collected juice is discharged to the juice discharge port 651 by the shape of the juice discharge passage 65 and also by centrifugal force and vortex caused by the rotation of the juice filter 50.

As shown in FIGS. 6 and 7, the inlet 652 of the half moon-shaped juice outlet 651 is formed slightly eccentrically in the center of the front face 11 of the body 15, which causes the body 40 to face outward. The inclined to the bottom side 421 is expanded. The juice discharge path 65 gradually decreases in the same direction as the rotational direction of the motor 43 starting from the half moon vertex 654 of the juice discharge inlet 652 and comes to the center of the juice discharge inlet 652 to obtain the lowest point. It forms a slope. This inclination is formed in a semi-circular shape to solve the problem of the manufacturing method due to the sudden difference in the juice outlet 65.

This is for the smooth discharge of the juice by centrifugal force by the rotation of the juice filter 50 and the vortex as mentioned above, and furthermore the juice is passed through the juice discharge inlet 652 along the circular juice discharge passage 65 To prevent it.

At the end point 655, which descends from the semicircular vertex of the juice discharge inlet 652, a smooth line having a radius of 1 mm to 2 mm is formed to prevent the juice from splashing upward above the juice discharge path 65.

A clutch 44 coupled to the motor shaft 431 of the body 40 is disposed inside the juice discharge passage 65, and the juice filter 50 is engaged with the clutch 44.

When the juice filtered from the juice filter 50 enters the main body 15 mounted inside the juice outlet 65, it may cause fatal damage to the motor 43. In order to block this problem, the juice discharge passage 65 is bounded inward from the juice discharge passage 65, the inner wall 656 is formed. The juice outlet passage wall 656 is manufactured to be positioned in the middle of the support plate 55 and the lower rim 52 of the juice strainer 50 and its height is slightly lower than the lower side of the support plate 55.

The semi-circular juice outlet 651 is designed in a four-sided block shape to improve the juice splashing problem, which is the most common problem that can occur in the juice outlet 651 of a common juicer or juice extractor. The above problem was solved by attaching an opening and closing device 67 to 653.

The juice outlet 651 started from the steep slope 657 of the juice discharge path is placed in the juice guide 60 in the opposite direction to the waste outlet 615 to extract the juice containing no residue, the lower side It was inclined so as to be naturally discharged without being disturbed by the load of the juice or by the centrifugal force of the juice filter 50 or the vortex of the juice.

The juice outlet 651 has a straight upper membrane 658 on the upper surface, and the remaining three surfaces form a semi-circular smooth radius. The upper membrane 658 ends at half of the length of the juice outlet 651 extending to the outside, and the upper plate 671 of the opening and closing device 67 to be described later at the portion where the upper membrane 658 ends. Abuts. In addition, since the juice guide 60 is made of plastic, the juice outlet 651 may be fluid due to impact or elasticity of the material itself, so that the upper membrane support 659 is installed to improve the juice outlet 651. Two sides of the semicircular juice outlet 651 are connected to the step wall 612 at the upper portion of the juice guide 60 from both sides of the upper membrane 658 to the line where the upper membrane ends.

The end portion 653 of the juice outlet 651 having a semi-circular cross section is also semi-circular, and a protrusion 660 for attaching the opening / closing device 67 on both sides of the tip protrudes outward from the outer wall.

In addition, a cornice 649 is formed to protrude from 1 mm to 2 mm downward from the lowermost center of the radius, which is the center of the semicircular shape, in which juice intermittently falling from the outlet 653 of the juice outlet 651 moves along the juice outlet outer wall. To prevent it from falling and drop it correctly into the juice cup suggested by the user.

It is common that the juicer manufacturer does not separately supply a cup of a specific shape for the juicer to take the juice extracted from the body 10 into a cup commonly used by a user, and this may cause various problems in another aspect. do.

That is, after the user inputs the fruits and vegetables to the inlet 301, the juice coming out of the juice outlet 651 is provided with the juice cup is either seeded at the end of the juice outlet 651 or continuously. Therefore, this caused a problem that the juice flowed to the floor and the mess was made when the user changed the juice cup when the juice cup was full.

In order to eliminate this inconvenience, the opening and closing device 67 is attached to the juice outlet 651 to allow the user to open and close the outlet as needed. As mentioned above, protrusions 660 are formed at both ends of the juice outlet 651, and the hollow part 673 of the rotation tube 672 is inserted into the protrusions 660 to assemble the opening and closing device. At this time, the handle 674 is directed upward from the main body 10 and is positioned outside the juicer cover 30.

The juice outlet opening and closing device 67 is a state in which the user opens the opening and closing door 675 by turning the handle 674 of the curved surface falling out about 70 degrees when the user comes out of the juice, that is, the end of the juice outlet 65 ( 653), on the contrary, when the juice cup is changed or moved, the handle 674 is turned downward so that the juice outlet 651 is closed by the opening / closing door 675 so that the juice does not come out of the juice outlet 651.

The shape of the opening and closing door 675 is the same as the shape of the juice outlet 651 but slightly larger in size. The reason is that the stop wall 676, which controls the stop of opening and closing at the end, covers the juice outlet 651. The juice outlet opening and closing device 67 made of elastic rubber material or plastic is the juice outlet 651. Due to the friction on the contact surface with the juice temporarily traps the juice in the juice outlet 651, the stop wall 676 is added to keep the friction smoothly.

In addition, the top plate 671 has an additional function in addition to the original function of the opening and closing device 67 to give a more powerful function in the juice outlet 651. The juice exiting from the juice outlet (65) is moved to the juice outlet (651) where the phenomenon of juice splashing by the vortex of the juice or the rotational force of the juice filter (50) as mentioned above occurs. In order to improve this phenomenon, the upper outlet is installed in the juice outlet 651, but the upper plate 671 of the opening and closing device 67 functions as the upper barrier. When the open / close door 675 is opened, the upper plate 671 is opposed to the upper membrane 658 at the opened upper side of the juice outlet 651, so that the flowing juice is smoothly discharged to the juice outlet 651.

Juice Strainer (50)

The juice filter 50 is configured in the shape of a circular shape so as to suit the rotational force of the motor 43 that rotates at a high speed.

Juice filter 50 is a support plate for supporting the juicer blade 53, the juicer blade 53 for crushing foods such as fruits and vegetables that are introduced into the inlet 301 of the juicer cover 30 to separate the juice and residues ( 55, a center frame 56 rotating in engagement with the clutch 44 of the main body 15 integrated in the lower portion of the support plate 55, a lower edge 52 formed at the outer side of the support plate 55, and a lower edge 52. Stainless steel sheet filtering net 54, the lower edge 52 and the upper edge 51 for supporting the filter net 54 and the upper membrane that is the outer edge of the upper edge 51 is inserted into the support (511) have. Juice filter 50 is carefully designed because the difficulty in manufacturing method is very high in functionality and extremely important.

The support plate 55 is a circular plate with a plurality of holes formed in the center and the inside thereof, and three bonding rods 551 are attached to the upper surface thereof, and the center frame 56 is integrated on the lower surface of the juice filter 50. It is a basic framework. A perforation 552 is formed at a central portion of the support plate 55, which is a portion receiving the rotational force from the clutch 44 attached to the upper portion of the main body 15 by the motor shaft 431. This is a portion into which the upper protrusion 441 of the clutch 44 is inserted, which is slightly larger than the diameter of the protrusion 441. Although the juice filter 50 is completely in close contact with the clutch 44, it is advantageous in terms of vibration or noise of the juice filter 50, but it is inconvenient when the user mounts or detaches the juice filter 50 to the main body 15. I can feel it.

In this respect, the diameter of the projection 441 of the clutch 44 is closely related to the diameter of the central hole 552 of the support plate 55. The juicer 10 according to the present invention achieved two opposite performances by designing a gap of two parts in diameter of 10 μm to 500 μm.

The upper surface of the support plate 55 is easily coupled with the juicer blade 53 coupled thereto and locally to prevent the flow or bending of the juicer blade 53 that may occur in contact with the lower surface of the juicer blade 53. A protruding end 553 was formed, and a joining rod 551 having three circular cross sections divided by 120 ° with respect to the center axis 57 was installed upward from the top surface of the support plate 55.

The joining rod 551 is exactly centered with the joining hole 533 of the juicer blade 53, and the cross section of the joining rod 551 decreases as it protrudes upward. If the cross section is conical shape and the bonding hole 533 and the cross section coincides with the cross section is difficult to bond because it is improved and the bonding is bonded by ultrasonic fusion method. The center frame 56 extends downward in a circular shape at about the same diameter as the bonding rod 551.

Six clutch bongs 561 are formed at the middle height of the extended center frame 56 at the same angle in the center axis 57. When the juice strainer 50 is coupled to the clutch 44, the support plate ( The protruding end 554 of the radiation of the lower surface of 55 is in contact with the upper surface 445 of the clutch 44, and the engagement rod 561 is engaged with the diamond bar 448 of the clutch 44 to rotate the clutch 44. Is passed. The circular cross section of the squeezing rod 561 has a large kinematic meaning. When the user operates the juicer, the squeezing rod of the juice strainer 50 is inevitably coupled to the juice filter 50. The 561 is coupled along the side surface 446 of the clutch 44, and is smoothly engaged in the portion without the rhombus 448, and in the portion where the rhombus 448 is present, the upper oblique surface of the rhombus 448 ( 449, the user can be smoothly coupled without any resistance, when the electric power is applied to the motor 43, the diamond bar 448 of the clutch 44 in the rotation direction of the motor 43 rotates the juice filter 50 Pulling down the bong 561 of the juicer 50 is rotated by the complete combination is receiving a sufficient rotational force from the clutch 44 at the same time the vibration that can occur from the incomplete coupling at the same time is basically blocked the juicer 10 safely use Can.

In addition, the reason why the number of the four bongs 561 of the juice strainer 50 is three lozenges 448 of the clutch 44 is the central axis when the rotational force of the clutch 44 is transmitted to the juice strainer 50. By rotating only 60 ° as a reference to 442, the protruding rod 561 can be contacted, so that the initial impact of the rotational force of the motor 43 is reduced. In addition, when the juice filter 50 is removed from the clutch 44, the juice filter 50 is removed along the lower inclined surface 450 of the diamond bar 448 of the clutch 44, so that the coupling and disassembly can be performed very conveniently. have. The support plate 55 on the top of the bong 561 of the juice filter 50 is perforated, which is an inevitable structure in the mold fabrication of the bong 561.

The lower edge 52 forming the outline of the support plate 55 has a circular structure extending downward from the curved surface having a radius of 1.5 mm to 3 mm in the support plate 55. The juice strainer 50 coupled to the clutch 44 has a lower rim 52 coupled to the outer portion of the inner wall 656 by the juice discharge of the juice guide 60, which is connected to the body of the juice discharge passage 65. (15) This is to prevent the phenomenon of splashing inside.

The lower edge 52 of the juice filter 50, which rotates at high speed, forms a film of air on the inner wall 656 to discharge the juice, thereby preventing the above phenomenon. The diameter of the lower rim 52 is slightly larger than the juice outlet furnace 656 and its height is slightly above the juice outlet furnace 65.

An important role of the lower rim 52 is also to support the filtration net 54. The filter net 54 is made of a stainless steel sheet in which micropores 541 are periodically arranged, one end of which is 542 and 543 as sharp and rough as other steel plates. The filter net 54 is inserted into the lower rim 52 to be manufactured, but the lower rim made of plastic can be manufactured. As will be described later, the inner periphery of the lower edge 52 penetrates into the perforation 544 formed below the filtering net 54 to tightly confine the filtering net 54 so that the filtering net 54 can accurately occupy space. This effect is associated with the upper rim 51 of the juice strainer 50.

The upper rim 51 supporting the upper side of the filtration net 54 can find its role not only in the juice strainer 50 but also in the juice guide 60. The upper rim 51 having an uneven support 511, which is formed at the top of the filter net 54 and has a flat plane 512 formed thereon and is periodically repeated outside, has an inner wall 513 of the filter net 54. It extends at the same angle as the residue discharge angle ε, and the same angle that allows the residue from the juicer blade 53 along the filter network 54 to be discharged flexibly to the residue guide walls 309 and 310 of the juicer cover 30. The diameter of 51 is slightly smaller than the inner wall 613 of the juice guide 60.

The lower surface 514 of the upper rim 51 is located slightly higher than the upper end face reduction portion 681 of the juice guide 60. As a result, although it is mentioned in the juice guide 60, the support 511 formed at the outer side rotates on the dregs discharge path 615 of the juice guide 60 to discharge the remaining dregs to the dregs outlet 615. It plays a role.

The filter net 54 joins two individual filter nets 548 by spot welding from the support plate 55 to an inverted cone shape. The individual filter network 548 is composed of a first region 547 in which a plurality of micropores 541 are arranged periodically, and the center 549 of the first region 547 is the central axis of the juice strainer 50. 57) in the first region 547, the micro holes 541 are arranged horizontally and the micro holes 541 are long holes having a length of 0.3 mm and a length of 1.6 mm. Only juice is arranged at intervals of 1 mm in length and 0.6 mm in length, and the foodstuff cut by the juicer blade 53 goes up the upper rim 51 along the filter net 54 while the juice and the dregs are mixed. (54) is removed and the rod-shaped debris exits to the debris outlet 615.

The upper and lower portions of the filter net 54 are formed with holes 544 and 545 larger than the micro holes 541 periodically arranged at regular intervals at the ends thereof. The holes 544 and 545 penetrate the upper edge 51 and the lower edge. To support the filtration net 54. Also, in order to facilitate work when spot welding from the individual filter nets 548 to the filter net 54, the joint reference holes 546 having a diameter of 0.5 mm to 2 mm are formed on both sides of the upper and lower large holes 544 and 545, respectively. Four are formed and two individual filter nets 548 are overlapped and welded based on the joint reference hole 546.

The fabrication of the filter net 54 generates micropores 541 and other pores by metal corrosion by the film. The holes of the fabricated filter net 54 are beautiful and clean micropores different from the processing of other plate materials. (541). The thickness of the filter net 54 is produced in a variety of common juicer or juice extractor, but the juicer 10 according to the present invention is used to prevent the debris from exiting the micropores 541 by using a stainless steel plate of 0.1mm to 0.3mm Meticulously crafted.

The bonded filter net 54 maintains a constant ε angle from the support plate 55, which is designed for practical use so that food products cut by the juicer blade 53 are most appropriately subjected to centrifugal force. May be caught in the microholes 541 of the filtering network 54 and may not be discharged. These angles are manufactured differently by each manufacturer, and the juicer designed the angle ε to be 57 °, which is the most appropriate angle.

The juicer blade 53 coupled to the three joining rods 551 attached to the support plate 55 is a main part that serves to separate food into juice and debris by cutting foodstuffs fed into the inlet 301.

The juicer blade 53 is a toothed blade 531 formed in a circular plate along the rule of the involute curve. The outer portion is slightly smaller than the outer diameter end 555 of the support plate 55 of the juice strainer 50, but the gap is negligible when the juicer uses or cleans the juicer or foreign matter.

The center of the juicer blade 53 is a difficult part for cutting food in practical use, the juicer 10 according to the present invention is to eccentric the inlet 301 mentioned in the juicer cover 30 to solve this problem. . And by forming a blade 534 in the center of the juicer blade 53, the effect was doubled. The length of the blade 534 is 2mm to 4mm and the height was set to 1mm to 2mm in the same manner as the saw blade 531.

The saw blade 531 is formed by the rule of an involute curve. The foodstuff is put into contact with the area of the juicer blade 53 while the rotating saw blade 531 passes through the entire area of the foodstuff to achieve a smooth cutting. To that end, the ruler of the juicer blade 53 is designed as an involute curve.

The overall shape of the saw blade 531 is wedge or serrated and triangular at the sides. The size of the tooth blade 531 is closely related to the micropore 541 of the juice strainer, so the size of the micropore 541 must be considered when designing the size. The debris cut by the saw blade 531 is not to escape to the fine hole 541 and the juicer 10 according to the present invention is larger in size and width than the fine hole 541 of the saw blade 531 1 mm to 2 mm.

Body 40

Body 40 is an important part that becomes a skeleton in the juicer (10) is equipped with a motor 43, which is a substantial drive unit, and the control unit for controlling the movement of the motor 43, the switch unit, the juice guide from the body 40 60 is attached to the body clasp 450 that combines the juicer cover 30. And the bottom plate 90 that bounds the body 40 from the surroundings is coupled by a screw 25, and some accessories are added to the bottom plate 90 to block vibration and noise.

Hereinafter, the configuration coupled to the body 40 or disposed inside the body will be described in connection with the structure of the body 40.

The motor 43 is a single-phase AC commutator electric motor suspended by a specially manufactured screw 47 in contact with the dustproof ring 46 inside the body 40. The motor 43 is firmly configured by the top frame 436 and the heart 437, which is a key factor that determines the performance of the juicer 10.

The motor 43 of the juicer 10 according to the present invention is manufactured in a very special structure compared to a general motor, and the structure is concentrated on the top frame 436. This technology is to attach the ball bearing 438 to the central portion of the upper frame 436, which is the conventional motor 43 is attached to the oilless bearing does not reduce the noise or vibration to the user has anxiety or discomfort Compared to this, the motor 43 significantly reduces such noise and vibration, which is significant. The ball bearing 438 is much more expensive than the oilless bearing, but the performance is much better.

One outer surface of the upper frame 436 is formed with two circularly protruding ends 439 and a hole for mounting screws from the end surface of the end is drilled. As will be described later, the protrusion 439 is coupled to a speed detecting unit SE1 for transmitting a signal of the motor speed to the motor speed regulating device 80.

The cooling fan 434 is forcibly pressed into the motor shaft 431 from the center line of the protrusion 439. The cooling fan 434 has the following two effects.

The first is to cool the motor 43 whose temperature rises by the electric current applied to the motor 43 which rotates at high speed with the surrounding cool air. This is a part regulated by the related laws of juicers and juice extractors, and the juicer has a low temperature of the motor 43 sufficiently to satisfy these regulations.

Another aspect is the speed of the motor 43, which was mentioned earlier. Food products such as fruits and vegetables that are put in can vary widely in thickness and length. The motor 43 is a large sized food products in the processing of such a variety of food products, the area is cut on the juicer blade 53 is large, the rotation speed of the motor 43 is reduced, in the case of small food products are cut on the juicer blade Since the area is small, the rotation speed of the motor 43 is only slightly reduced.

Since the motor 43 is not able to reduce or increase the speed according to various sizes of food products, the juicer according to the present invention has a motor speed control circuit centering on the motor constant speed device 80 to maintain a constant number of revolutions of the motor 43. The cooling fan 434 serves to transfer the correct number of revolutions of the motor 43 to the associated speed detecting unit SE1. A plurality of individual vanes of the cooling fan 434 is to pass through the speed detector (SE1) at regular intervals sequentially to detect the speed accurately.

In view of this aspect, the motor 43 has another feature that the cooling fan 434 is installed in the upper frame 436 of the motor 43. This protects the user from the danger that the cooling fan 434 hits the motor cover 49 and deforms when the motor 43 is shaken inside the main body 15 due to the assembly or transportation of the juicer.

The upper frame 436 has a ball bearing 438 attached to the center and a motor shaft 431 is inserted into the center to rotate. A protruding rod (not shown) having a circular cross section and a hole for attaching a screw is formed on the outer side of the outer wall of the circular ball bearing 438 and extends in the screw direction 432 of the motor shaft 431. Three protrusions are evenly disposed on the central axis 402 of the motor 43, and are coupled to the hollow portion of the anti-vibration ring 46 coupled to the body 40. The side wall 952 of the protruding rod 951 is surrounded by an anti-vibration ring 46 made of a rubber material having elasticity and excellent vibration absorption capability, and the upper surface 953 is a recess 42 of the upper surface of the body 40. It is fitted in the hole 422 of the) and is in close contact with the end of the special screw 47 is formed to cross the motor cover 49, the screw 47 is inserted through the hole.

Motor cover (49)

The motor cover 49 covering the periphery of the motor 43 is made of flame retardant plastic and has excellent thermal insulation. The motor cover 49 has a cylindrical shape in which a bottom surface is drilled and the remaining five surfaces are blocked, and a local functional hole is drilled.

Motor cover 49 has a variety of functionally, the first is the motor cover 49 is attached to the body 40 serves to couple the duct structure to each other. In essence, the motor cover 49 is coupled to the body 40 by screws through two holes 491 symmetrically disposed on the motor axis 402 of the upper surface, which is lower from the lower surface of the recess 42 of the upper body. The two centers arranged in contact with the hollow protruding bar 111 are screwed toward the body 40 from the motor cover 49. At this time, the position is determined by the coupling hole 493 disposed at a predetermined angle of the upper surface of the motor cover 49 for fixing the motor 43, and can be easily coupled.

In the center of the motor cover 49, a center hole 494 is formed to penetrate the motor shaft 431, and a hole 493 through which the anti-vibration ring 46 as described above passes through the center axis 402 is formed therein. Three are formed symmetrically about). The diameter of the through hole 493 is slightly larger than the outer diameter of the anti-vibration ring 46 so that the position of the through hole 493 can be determined as close as possible when the motor 43 is coupled. A circular wall 495 that is open to the central axis 402 extends to the upper surface 492. The wall 495 is designed to be larger than the inner diameter of the engaging portion 111 of the body 40 in contact with the through hole 493 to facilitate the motor cover 49 to be coupled to the body 40. ), A plurality of linear pillars 496 are installed in the direction of the axis 402, respectively, which is a coupling portion of the wall 495 and the body 40 when the motor cover 49 is coupled to the body 40. (111) Consideration is given to reducing friction with the inner wall.

The upper part of the circular side wall 497 of the motor cover 49 is formed with a window 498 which communicates with the inside and the outside, which is precisely designed to double the cooling effect of the cooling fan 434 of the motor 43. It is installed parallel to). In addition, a similar window 499 is installed at the bottom, which removes the shape of the relatively coupled portion to avoid the brush portion 954 of the motor 43 when the motor 43 is coupled.

On one side of the circular side wall 497, a plurality of circular protruding rods 500 having empty centers are provided. The purpose of the protrusion bar 500 is to couple the motor speed setting device 80 to be described later, the end of the protrusion bar 500 is stepped. The material of the motor speed regulating device 80 is made of the above shape to reduce the friction after the coupling in order to compensate for this, the elasticity is lower than that of the motor cover (49).

In addition, in the description of the juicer 10 according to the present invention or the center of the circular protrusion bar for the coupling to be described in the future should not be overlooked that the end is stepped.

A straight support wall 501 is erected on the upper side of the motor cover 49 to which the motor 43 is coupled. The wall 501 is the core 955 of the motor 43 after the motor 43 is coupled. It extends slightly above the top and stands so wide that it does not come into contact with the coil 956 wound inside the motor core 955.

In order to assemble the structure associated with the body 40, the motor 43 is first inserted into the motor cover 49, and the motor speed adjusting device 80 is screwed to the motor cover 49. Then, the lead wire of the speed selector 85 screwed to the switch unit 12 and the lead wire of the motor 43 are attached to the motor speed regulating device 80, and the motor 40 is mounted on the body 40 in which the anti-vibration ring 46 is fitted. Screw on the cover (49). In addition, the motor 43 is also screwed to the body (40). Then cover the bottom plate 90 to the body 40 and then fasten with a screw.

A plurality of protrusion bars 502 for fixing the bottom plate 90 are installed at the bottom of the motor cover 49. The protrusion bars 502 are coupled to each other by a bottom plate 90 supporting the bottom of the main body 15. Unlike the protruding rods, it is firmly supported.

The support plate 503 extending from the lower end to the upper side is provided at a constant angle, and a protruding rod 502 is formed at the contact portion of the support plate 503. The upper part of the protruding rod 502 and the upper part of the support plate 503 are integrated by a separate cover 504. The protruding rods 502 and the support plate 503 have a triangular shape as a whole, which is the most stable structure in the mechanical structure.

When the upper portion 492 of the motor cover 49 is coupled to the body 40, the lower base plate fixing protrusion 502 is positioned slightly higher than the fixing round rod 901 of the base plate 90. That is, a slight gap is generated between the protruding rod 502 and the circular base 901 of the base plate 90. When the base plate 90 is fastened with the screw 902 from the base plate 90, the base plate 90 moves toward the motor cover 49. Slightly bent to serve to ensure that the rim of the body 40 and the base plate 90 is completely in close contact.

An additional function of the motor cover 49 is a function of protecting the internal wiring of the motor speed regulating device 80 and the speed selector 85 linked from the high-speed rotating motor 43, which has a double-sided function. That is, the role of protecting the associated structure of the motor 43 and at the same time serves to protect the associated structure from the air emitted from the motor 43 rotating at high speed and carbon powder mixed in the air.

Another important function of the motor cover is that the cooling fan 434 of the motor 43 forms a flow of air, that is, an air passage, to smoothly cool the motor 43. This can be found in terms of hydrodynamics. The interior of the body 43 does not form an effective and sufficient aeration path to cool the motor 43 such that the various structures are complicatedly installed and blocked or interfered with the aeration path. Although it may not be possible, the motor cover 49 of the present invention effectively serves to form a flow path. The motor 43 coupled to the inside of the motor cover 49 that occupies the limited space is cooled rapidly and efficiently by the cooling fan 434.

The grate-shaped vent hole 419 is formed in both sides of the lower end 404 of the body left wall 406 so that the air sucked by the cooling fan 434 of the motor 43 and the wing 444 of the clutch 44 is fixed. To form a vent to cool and discharge the motor 43.

Dustproof Rings (46)

Before the motor cover 49 is coupled to the body 40, the vibration ring 46 is fitted. The vibration ring 46 has a cylindrical shape, and the hole therein is the same as the protruding rod 951 of the motor 43. It was formed. The diameter is slightly larger at the same horizontal position of the protruding rod 951 and the internal hole also has an angle of decreasing upwards as the protruding rod 951 has an angle of decreasing upwards.

The upper side and the lower side have a flat surface 461, and the outer side has a recessed strip 462 which is slightly smaller than the diameter of the center hole 422 so as to fit in the center hole 422 of the engaging portion of the body 40. The height of 462 is slightly larger than the thickness of the central hole 422 of the body 40.

The anti-vibration ring 46 made of a flexible rubber material with elasticity has an inner hole 463 and a top contacting the vibration generated from the motor 43 with the screw 47 having a stage to which the motor 43 is fastened. Absorbed from the 461a prevents the transfer to the body 40 and adds some fluidity to the motor 43.

Screw (47), screw cover (48)

Screw 47 for fixing the motor 43 to the body 40 is the head portion 471 is formed with a cross-shaped groove 472 and the body 473 is formed in a step that is reduced in diameter by a slimy expansion At the bottom there is a threaded portion 474 which is formed as a tubular tab.

The screw cover 48 for sealing the screw 47 from the body 40 to the upper side of the screw 47 is plated is inserted into the body 40. Screw cover 48 is also made of a rubber material with elasticity similar to the dust-proof ring 46 and insert the screw cover 48 after fastening the screw 47 to the body (40).

The screw cover 48 prevents the user of the juicer from easily removing the screw 47 due to curiosity or other reasons, and prevents the juice or other foreign matter from penetrating into the coupling hole 422 into which the screw 47 is inserted. Although the outer diameter of the screw cover 48 is designed to prevent the same as the diameter of the coupling hole 422 of the body is not easily separated after insertion and the upper surface 481 is slightly entered than the top 42 of the body 40.

Base plate (90)

The bottom plate 90 supporting the bottom of the main body 15 is exactly coincident with the lower side of the body 40. Typically made of plastic, the upper surface 904 is extended or independent from the wall 905 and the protrusion 90, which is coupled to the motor cover 49, the wall 903 to accurately position the outer wall of the body 40 A ladder-shaped rolling prevention 906, a power line insertion wall 907 for guiding the power line to the motor speed regulating device 80 and the speed selector 85, and the floor of the kitchen where the juicer is placed. And a foot 920 that blocks and prevents rolling, and structures attached to the center portion.

At the bottom of the base plate 90, a bottom end 908 is formed which sits downward in the direction of the center axis 402 of the motor 43. The outer end of the bottom end 908 is surrounded by a circular boundary wall 909. . The wall 909 is associated with the motor cover 49 to flow the air flowing into the motor cover 49 in one direction and to reduce noise caused by the vortex of the air. The center of the bottom end 908 is a rectangular hole 910 is penetrated through the hole for the service of the juicer may be formed by inserting the driver of the date through the hole formed on the lower end of the motor shaft 431 In order to be able to assemble or disassemble the clutch 44 mounted on the upper end of the motor shaft 431 in the state in which the rotation of the motor 43 is restrained in the groove 440. This is a method that can practically disassemble or assemble the clutch 44 without disassembling the base plate 90 of the main body 15.

An inclined wall 911 having a constant angle from the bottom end 908 to the boundary wall 909 is a passage 912 through which cool air is introduced by the cooling fan 434 of the motor 43. The passage 912 is arranged periodically and is hydrodynamically designed.

The upper surface of the bottom end 908 is provided with a plurality of upwardly extending walls 913 to prevent the bottom end 908 from bending. The bottom of the bottom end 908 is designed to be higher than the bottom of the periphery where the juicer 10 is located but lower than the bottom 914 of the base plate 90 to reduce noise in the air. The upper wall 905 extending in the form of a checkerboard of the bottom is installed, which also serves to prevent the bending of the bottom surface (904).

A plurality of protruding rods 901, which are fastening portions for coupling with the motor cover 49, have upper and lower portions formed in steps. The upper steps 915 extend from the outer outer wall to the upper surface, and then enter a predetermined portion from the upper surface to the center. Stairs 915 are formed with a slope at. This step 915 is to find the correct position even when the protrusion bar 901 is not coupled at the correct position when the motor cover 49 is assembled.

The lower staircase 916 is for another purpose, so that the head of the screw to join so as not to protrude from the bottom of the bottom 914 is recessed slightly above the height of the head of the screw at the bottom 914.

The outer wall 916 is formed in a double thickness, the lower surface 917 is in contact with the bottom surface 408 of the body 40 and the inner wall 409 of the bottom surface 408 of the body 40 is at the lowest point. It is restrained by the rolling brace 906 of the base plate 90 by a fixed height. The body 40 is made of elastic plastic so that the body 40 and the bottom plate 90 are not separated due to the impact applied to the body 40. One side upper wall 918 of the tapered thickness of the bottom plate 90 is smaller than the opposite side wall 409 of the body so that the body 40 and the bottom plate 90 are coupled to each other so that the bottom plate 90 is formed at the bottom surface. Not only to smoothly connect them, but also formed a band 903 at regular intervals to give a sense of stability to the body (15).

A circular protruding rod 919 for coupling the switch portion 12 to the position slightly inward from the outer wall of the front right side of the bottom plate 90 is extended upward. As will be described later, the switch portion 12 of the body 40, which is designed to be interchangeable with the switch portion 12 of one speed and the switch portion 13 of one speed used in the juicer 10 according to the present invention ( The switch 12 is coupled to 58 and the protrusion 12 of the base plate 90 is fastened by a screw to secure the coupling. The protruding rod 919 is a cylindrical shape in which a circular cross section is reduced to the upper side of which the inside is empty, and its upper surface maintains a constant angle with the bottom.

The power line insertion wall 907 serves as a passage connecting the power line 931 from the outside of the main body 15 to the inside. In addition, the power line 931 is firmly supported so that there is no flow, so that the power can be stably supplied. In addition, starting from the portion 932 where the upper side of the outer wall 916 is cut, walls 933 having a constant height at the bottom are continuously integrated and are installed to be symmetric with respect to the center wall 934.

The center of the circle is extended so that the protrusion bar 935 is empty inside the same height is considered to be fastened with a screw when the flow caused by the individual tolerance of the power line 931. The foot insertion part 936 provided at the corner of the bottom bottom surface of the base plate 90 is surrounded by a circular wall, and a plurality of pillars 937 are provided in the same direction as the axial direction along the inner wall surface. The length of the foot insertion portion 936 is longer than the length θ of the foot 920 and the diameter is slightly larger than the diameter ρ of the foot.

The pillar 937 of the inner wall is smaller than the diameter ρ of the foot, because when the foot 920 is inserted into the entire wall surface, the friction force is excessively generated, which is difficult to assemble. Therefore, when the pillar 937 is placed on the inner wall and the pillar 937 is inserted into the friction surface, the assembling is easy and the coupling force is also firm.

Feet (920)

The foot for supporting the juicer 920 is made of a rubber material having the same or similar elasticity and excellent vibration absorption capability as the anti-vibration ring 46 coupled to the upper surface 42 of the body 40.

In order to eliminate the difficulty of insertion due to the pressure that may occur inside the base plate 90 during insertion, the hole 921 having a diameter of 0.5 mm to 2 mm was formed to relieve pressure.

Since the process of insertion is described above, only the function of the foot 920 will be described here. The function of the foot 920 is to stably support the main body 15 by the wide bottom 922 of the lower part, as well as the possibility that the vibration of the motor 43 is primarily removed by the anti-vibration ring 46 but may be transmitted. Be prepared in earnest for dustproof function.

Clutch (44)

The clutch 44, which is screwed by a predetermined length at the upper end of the motor shaft 431, is a device that transmits the rotational force of the motor 43 to the juice filter 50 and has a circular shape. The clutch shaft 45 made of a copper alloy inside the clutch 44 was manufactured separately and manufactured by insert injection method when manufacturing the clutch 44. The clutch 44 was made of engineering plastic.

The clutch 44 has an important meaning beyond the function of transmitting rotational energy of the motor 43. The motor 43, which is fastened by screws at the top of the body 40, should be aligned with the center axis 402 of the motor 43 to exactly match the center axis 402 of the body 40 and describe this arrangement. For clarity, the positioning devices described above should be formed and the central axis 442 of the clutch 44 aligned with the motor axis 402. As a result, the juice filter 50 coupled to the clutch 44 may rotate about the central axis 57 to exclude vibration or noise.

The manufacturing of the clutch 44 is designed and manufactured with special attention differently from other apparatuses, as is the clutch shaft 45 which becomes the center of rotation of the clutch 44. The clutch shaft 45 is manufactured by a high precision numerical control lathe, and the dimensional accuracy of each part is manufactured in units of microns (µm).

Cylindrical clutch shaft 45 is empty inside, but the upper end 451 is formed with a female thread coupled to the male screw 432 of the end of the motor shaft 431, the direction is the direction of rotation of the motor 43 and In the exact opposite direction. This is to prevent the user from accidentally loosening the clutch 44 coupled with the screw while using the juicer 10 in the same direction as the pressure applied when cutting by the juicer blade 53 by the user input the food.

The lower portion 452 of the screw portion extends downward in a flat cylindrical shape, and the extended portion comes into contact with the bottom cylindrical surface of the screw portion of the motor shaft 431. This is a technical means for aligning the above-described axis by inserting at the time of assembly. The clearance between the cylindrical surface 452 of the clutch and the cylindrical surface 433 of the motor shaft 431 is 5 to 50 µm, and is precisely inserted so that a 'tight' pressure is released when the two structures are separated.

As shown in FIG. 12, the outer surface of the clutch shaft 45 is positioned around the outer surface of the uneven portion 453 formed at regular intervals while maintaining a constant interval from the bottom. The groove 454 is formed in the middle of the uneven portion of the outer surface in a shape for preventing the phenomenon of separation with the clutch 44. It is a shape that squeezes the wall in the axial direction from the outer surface, and the wall of the clutch is extended to prevent the detachment.

The outer periphery of the outer surface of the clutch shaft 45 is surrounded by a circular pillar 443 of the clutch 44, and a plurality of straight blades 444 are radially installed thereon. This blade 444 is another device for cooling the motor 44 together with the cooling fan 434 responsible for cooling the motor 43. The cooling vanes 444 extend outwardly from the outer surface of the pillar 443 and the extended surface extends upward again to contact the upper surface 445 and extend from that position to the outer wall 446.

The upper surface 445 has a projecting portion 441 protruding in a circular shape and is exactly in contact with the perforation 552 of the central portion of the juice strainer 50. The upper edge 447 of the protrusion 441 has a chamfer between 1 mm and 2 mm in length for ease of assembly when inserted into the punch 552 of the juice strainer 50. The outer wall 446 extends downward from the outer side of the upper surface 445 and the extended length does not reach the body 40 of the main body 15.

The outer wall 446 is formed with an evenly distributed rhombus band 448 at the central axis 442. The outer surface of the rhombus band 448 is also circular. Rhombus stand 448 is a substantial portion that transmits the rotational energy of the motor 43 to the juice strainer 50 is inclined from the center to both sides, the top 449 is formed and parallel to the surface diagonally from both sides as a starting point The bottom 450 is formed while forming an angle. A stage 455 having a larger diameter is formed below the rhombus band 448, and the outer wall 455 of the stage is in contact with the center frame 56 of the juice strainer 50. The protrusion 441 of the upper surface 445 is designed to support the juice filter 50 more firmly because the outer wall 455 is in contact with the juice filter 50 as the first constrained state. The outer wall 455 also has a center frame 56 and a gap of 5 μm to 50 μm of the juice filter 50.

Body 40 is designed in a shape close to the cuboid as a whole.

A circular recess 42 is formed at the top of the body, and a hole 424 for joining the coupling portion 423 for fixing the motor 43 and the motor shaft 431 to the recess 42 is formed. It is formed there is a low end portion 41 which is a space in which the body clasp 450 is located on both sides of the depression 42. The lower surface of the circular recess 42 having an open front face forms an angle ξ from the end of the circle to the bottom such that the juice outlet 651 of the juice guide 60 is not in contact. The lower end portion 41 to which the body engaging portion 66 of both side juice guides 60 of the upper side 42 is coupled is formed, which is the same straight line as the lower end portion 404 on which the body clasp 450 is mounted. However, the partition 413 is erected downward from the top of the body so that the bottom of the body coupler 66 of the juice guide 60 can be fixed. The lower end 404 into which the body clasp 450 is inserted has a width that is slightly larger than the body clasp 450 so that the body clasp 450 is completely flush with the body 40 on the outer surface and the body clasp 450 Enters toward the center rather than the outer wall to stop at the stairs 414 of the lower end 404, and the lower end of the lower end 404 is a smooth curved surface so that the finger enters when the user operates the body clasp 450 by hand. It is comfortable.

A hole 415 penetrating the inside and is formed in a portion oriented in one direction from the center of the bottom end 404, the safety switch operating portion 456 of the body clasp 450 is operated through this hole 415. The position exactly matches the safety switch actuating portion 456 of the body latch 450 and is larger in size than the actuating portion 456. Holes 416 communicating with the inside of the upper end of the step 414 of the bottom end 404 are symmetrically formed on both sides, and the pillar portion of the elastic plate 72 mounted to the body clasp 450 is formed. This is where 721 is inserted.

The lower end 404 described above is formed such that the left wall 406 and the right wall 407 of the body 40 are symmetric about the center axis 402 of the body 40. Therefore, the body clasp 450 And the elastic plate 72 is coupled to the juicer cover 30 and the tube structure in the left wall 406 and the right wall 407.

Inside the bottom end 404 of the right wall 407, there is a built-in device constituting a safety switch (S4) to enable the user to use the juicer 10 safely. The device constituting the safety switch (S4) is composed of a safety switch (S4) for electrically opening and closing the power supply and the switch frame 73 that is the frame of the safety switch (S4).

This safety device presents another extensibility in the manufacture of the juicer. The safety switch (S4) used at the double speed and the related elements of the method for controlling the motor 43, which has been briefly mentioned before, is attached. The structure is manufactured so that the safety switch (S14) used at one speed different from this juicer and the related structure attached thereto are interchangeable. The structure of the switch unit 13 and the safety device when controlling the motor 143 at one speed will be described later, and only the parts used at the dual speed will be described here.

A circular protruding rod 417 is formed below the inner end of the bottom end 404 to fasten the screw extending downwards to screw the switch 73, and the upper screw the switch 73. Guide 418 extends from the top surface and recess 42 of the body 40 to occupy the space before fastening. The switch frame 73 is separated from the switch frame 73 by two protrusion rods 731 and the safety switch S4 protruding staggered circularly from the bottom to fix the position of the safety switch (S4) in a plate shape of a certain thickness. The latch 732 is hooked so as not to combine the safety switch (S4).

Safety switch S4 is a micro switch generally used, and two holes 734 are alternately arranged, and an operation pin 733 is provided at a side to perform a substantial function. The clasp 732 rises a little larger than the height λ of the safety switch S4 from the bottom 735, inserts the safety switch S4 into the protruding rod 734, and then the bottom of the clasp 732 is the safety switch S4. ) And the clasp 732 is made of an elastic material, so when the safety switch S4 is inserted, it is slightly pushed to the opposite side of the safety switch S4.

A flow plate 735 is provided at a portion in contact with the actuating pin 733 of the safety switch S4, and the flow plate 735 is supported by an elastic band 736 having a structure in which elasticity is added.

Referring to FIG. 26, the elastic band 736 has a body latch 450 that combines the juicer cover 30 so that the safety switch operating portion 456 of the body clasp 450 enters the body 40 to enter the safety switch. The flow plate 735 of the mold 73 is pushed so that the operation pin 733 of the safety switch S4 is inserted into the safety switch S4 to allow the safety switch S4 to open and close the power supply. It is designed to be flexible and resilient. In the circular rod 737 protruding from the bottom, the elastic band 736 is expanded in a straight line, descending linearly and proceeding at a constant interval in the reverse direction of the progress direction, drawing a radius and drawing a radius again. Proceeding at regular intervals in the reverse direction and meets the fluid plate (735). The radial portion of the elastic band 736 is reduced in thickness from other portions are considered to be concentrated elastic action in this portion. And the elastic band 736 has a symmetrical shape of the upper side and the lower side around the flow plate 735 to prevent distortion or deformation even during operation by the body clasp 450 or when returning due to elasticity.

The flow plate 735 is a surface in which the inclined surface 738 angled toward the body wall is in contact with the safety switch operating portion 456 of the body clasp 450 at the initial operation. When the safety switch operating part 456 of the body clasp 450 enters the body through the through hole 415 of the bottom end 404 of the side wall of the body, it is fitted to the guide 418 of the upper end of the body and protrudes a rod ( The fluid plate 735 is moved toward the operation pin 733 by contacting the inclined surface 738 of the fluid plate 735 of the safety switch frame 73 screwed by the 417. As the body clasp 450 is completely seated on the body 40, the inner wall 740 of the safety switch operating part 456 moves to the side surface 739 where the oblique angle meets the inclined surface so that the flow plate 735 is a safety switch ( It is moved enough to operate S4).

The flow plate 735 is formed at a predetermined interval away from the bottom. A fixed plate 741 having a predetermined width at the end is installed on the opposite side of the flow plate 735 to screw the protrusion bar 417 of the body 40.

Elastic Plate (72), Body Clasp (450)

The elastic plate 72 plays an important role in clarifying the device coupled to the upper portion of the body 40 together with the body clasp 450 and driving the safety switch S4. The elastic plate 72 is attached to the lower end 404 of the body 40 by a hole 416 penetrating through the inside.

The elastic plate 72 is a form in which two cylindrical pillars 722 are connected by a plate made of an appropriate curved surface, so that the elastic force of the intermediate curved surface 724 is a fundamental force of the coupling force described above. Kinematically starting from the concept of a three-section link is that the elastic plate 72 coupled to the body 40 and the body clasp 450 coupled to the elastic plate 72 is the juicer cover 30 at the hook 451. The upper end of the body clasp 450 is coupled to the juicer cover 30 and the lower end protrudes from the body 40 by the inclined angle of the elastic plate 72 when it is inserted into the depression valley 322. do. Subsequently, when the lower side of the body clasp 450 is pushed in the body direction, the middle curved surface 724 of the elastic plate 72 is bent toward the center of the radius so that the body clasp 450 adheres to the body 40 and is completely in close contact. Later, the intermediate surface 724 of the elastic plate 72 is bent more than the initial intermediate surface 724 and less than the amount at which the extension lines of the two columns 722 and the side line of the body clasp 450 coincide. The elastic force of) pulls the body clasp 450 downward from the hook 451, which is the coupling portion of the juicer cover 30, so that the coupling force between the body 40 and the juicer cover 30 is maintained. The elastic plate 72 has a reduced cross section at both ends of the pillar 722 to form an extended pillar 723.

Body clasp 450 is a straight plate, the upper side of the hook 450 is formed and the lower side is a fixed portion 458 is formed. The hook 450 extends over the entire width of the plate, but at a certain interval from the top, an empty space 457 is formed and the space is extended at an angle toward the lower side so that the cross section has a hook shape. 30 is accurately coupled to the valley 322 and the mountain 320.

The lower fixing part 458 has a shape in which the obtuse wall extends upward and downward from the rear side and meets at an appropriate radius in the center, and the center wall 459 is thinner than other walls 425. In addition, a hole 426 is drilled in the upper portion of the center wall 459, and the column 723 of the elastic plate 72 is coupled to the hole 426. On one side of the fixing part 458, the safety switch actuating part 456 has a rectangular cross section with a thickness of the central part 459 and extends to the opposite side of the rear surface. The extended length is the length that passes through the flow plate 735 of the safety switch frame 73 when the front face coincides with the outer wall of the body 40.

Switch section (12)

The switch portion engaging portion is formed by the rectangular window 58 in the center portion projecting from the upper side to the lower side of the front right side of the body 40. The switch portion 12 is coupled to the window, and the outer surface of the switch plate 12 is formed in the same manner as the outer shape of the window 58.

The outer surface of the switch unit 12 has three operating rods 121 having flexibility to operate the switches S1, S2, and S3 of the speed selector 85 along the center line. The bow-shaped support 122 to be added is connected to the operating rod 121 from the outer surface and the operating rod 121 is extended inward at the same height as the outer surface. The end of the operating rod 121 faces the switch of the speed selector 85 at an interval of about 0.5 mm. A perforated hole 123 having the operating rod 121 as the center of the circle and the end of the support 122 as the radius is disposed at the same position as the operating rod 121.

A hole 124 into which the operation indicator lamp LED of the speed selector 85 is inserted in the upper left direction of the uppermost extension rod 121 is formed while being extended inward. The edge 125 is formed at a slight distance from the outer surface except for the lower side of the outer surface, which is in contact with the window 58 of the body 40 to determine the position of the switch unit 12.

The switch 12 has structures for supporting the speed selector 85, and a circular protrusion 126 having a hollow inside at a position symmetrical with a hole 124 for inserting an operation indicator lamp (LED). Is formed and the straight support 127 is extended from the lower side of the protrusion 126 in the right direction and connected to the support 128 of the same shape across the horizontal direction of the switch unit 12. In addition, a straight support 128 having a horizontal cross-section of the switch 12 is arranged at regular intervals from the lowest operating rod 129, and a circular protrusion 129 having an empty inside in the middle of the support 128. Is formed. The protrusion bar 129 and the switch unit 12 is coupled using a screw.

At the center of the switch unit 12, a hollow hollow protruding rod 130, which is vertically extended at a lower position than the lower actuating rod 129, is installed at intervals from the upper surface thereof, which is a body 40. After fixing the switch unit 12 in the structure is installed to fasten with a screw from the protruding rod 919 of the base plate 90. The protruding rod 130 is supported by several supports from the upper surface.

Motor constant speed 80 and speed selector 85

The control unit for supplying power to the motor 43 and operating the juicer at high speed and low speed is largely divided into a motor speed regulating device 80 and a speed selector 85, and the motor speed regulating device 80 has a motor cover 49. Is fastened with a screw and the speed selector 85 is coupled to the switch unit 12 using a screw. The motor speed regulating device 80 and the speed selector 85 having a rectangular shape are electronically designed.

As shown in FIG. 22, when power is applied to the power supply unit E1 in a state where the safety switch S4 is closed, all of the motor speed regulator 80 enters from the speed detecting unit SE1 and the speed selecting unit 85. The information can be processed automatically.

The process applies power to the motor 43 when the signal selected by the speed selector 85 enters the motor speed regulating device 80. Then, the speed detector SE1 checks the speed of the motor and supplies an analog signal to the motor speed controller 80. In one-chip microcomputer U1, the power of Triac TH1 is changed to maintain a constant speed, thereby keeping the motor speed constant.

In particular, in order to protect the motor 43 and the motor speed regulating device 80 from being constrained due to excessive amount of food being accidentally introduced, the one chip is not detected when the analog signal generated from the speed sensing unit SE1 is not detected. The microcomputer U1 is designed to cut off the power to the motor after 20 seconds.

That is, if the amount of food products to be put in the state in which the motor 43 is in operation or the mechanical 43 is constrained because the coupling is not smoothly mechanically, the motor 43 stops operation and blinks after 20 seconds at that time. The operation indication lamp (LED) stops blinking. Therefore, the user can visually easily know the operating state of the juicer.

It is designed to be easily recognized in appearance. When power is applied to the power supply unit E1, the operation display lamp LED is turned on. When the user selects a high speed or a low speed in the speed selector 85, the operation display lamp LED is turned on at a predetermined cycle so that the user can recognize that the motor 43 is operating.

As shown in FIG. 24, the motor speed regulator 80 includes a one-chip microcomputer U1, MICRO CONTROLLER, such as MICROCHIP 16C54 RC / P. This circuit connected the AC power supply E1 and the safety switch S4 in series so that the motor speed regulating device 80 can be supplied with power only when the safety switch S4 is closed. When power is supplied to the motor speed regulator 80, the speed selector 85 selects a speed and the motor 43 drives.

Check the rotational speed of the motor 43 by the speed sensing unit SE1 to generate an analog signal, and delay the phase with the resistor R1 and the capacitor C1 to improve the noise margin and apply it to pin 2 of the microcomputer U3. Set the reference voltage using resistor R3 and resistor R4 on pin 3 of microcomputer U3, and convert pin 1 and pin 3 of microcomputer U3 into resistor R2 and capacitor C12 and return them to amplify and convert digital signal from microcomputer U3. And supply to pin 3 of one chip microcomputer U1. Comparing the supplied digital signal with the data stored in the internal RAM of the one chip microcomputer to compensate the motor 43, it is possible to maintain a constant speed.

The principle of controlling the power supplied to the motor 43 is to adjust the amount of power supplied to the motor 43 by changing the phase of the GATE signal of the triac TH1 around the frequency input to pin 9 of the one-chip microcomputer U1. Ensure that you maintain a constant speed regardless of the size of the food or the pressure at the time of loading. If a fast switching transition occurs in the applied power supply, resistor R10 and capacitor C4 reduce the threshold voltage rise rate of the triac TH1 to avoid false triggering and prevent the triac TH1 from breaking, thus protecting the triac TH1. Resistor R12, resistor R13 and transistor Q1 are GATE auxiliary circuits of triac TH1, and transistor Q1 is used to consider the GATE current of triac TH1. Resistor R11, Capacitor C5, Rectifier Diode D1, D2, Electrolytic Capacitor C6, Zener Diode ZD1 is a part that creates a power supply of DC voltage of 5V so that the motor speed regulator 80 can operate smoothly. The function of is also possible.

Specifically, Zener diode ZD1 and electrolytic capacitor C6 were used to smooth the pulses in addition to rectifying diodes D1 and D2. A practical motor constant speed device (80) was technically designed to obtain the effect of rectifying and distributing the working voltage without reducing the heat generation and degrading the performance of the peripheral circuit device.

Oscillator X1 is a component that generates 4MHz of frequency necessary for internal operation of one-chip microcomputer U1, and microcomputer U2, resistor R7, and capacitor C3 supply reset signal to pin 4 of one-chip microcomputer U1. The main function is to make the initial operation state of the one-chip microcomputer U1 by delaying the time of about 18ms from the VDD rise time of the one-chip microcomputer U1 while the power is initially applied. Pins 1, 17 and 18 of the one-chip microcomputer U1 receive the signals of the switches S1, S2 and S3 of the speed selector 85 and send the desired motor speed to pin 6 of the one-chip microcomputer U1. Pin 12 of the one-chip microcomputer U1 visualizes the signal of the operation indicator lamp (LED).

Waste Receptacle (70)

After the juice has been extracted, the remaining residue can be separated from the surroundings by the residue bucket 70. Square tubular waste container 70 is larger than the waste guide walls 309 and 310 of the juicer cover 30 so that the wastes can enter the inside without splashing around. The bottom edge 701 is formed lower than the inside so that the juicer 10 is not shaken when the floor is not high. A handle 702 is formed from the middle of the front to the upper side of the handle 702 which is formed inward from the outside so that there is no locally protruding portion to add ease of packaging or transporting the juicer.

Switch cover (140)

In order to protect the speed selector 85 composed of electronic devices and to allow a user to easily select a desired speed, a switch cover 140 made of a film is attached to the outer surface of the switch unit 12. In order to increase the adhesion with the outer surface of the switch plate 12, a special adhesive is separately attached to the inner surface of the switch cover 140. The switch cover 140 exactly matches the outer surface of the switch unit 12 and has a thickness of 2 mm or less. The background color of the switch cover 140 is an opaque color, and the circle of the portion corresponding to the hole of the operation indicator lamp (LED) of the switch unit 12 is made transparent so that the light of the operation indicator lamp (LED) can be easily seen by the user. It was made. The part in contact with the operating rod 121 is arcuate and has elasticity. The outer surface displays a phrase corresponding to the high speed, the low speed, and the stop of the speed selector 85 to select the correct speed.

As a juicer compatible with the juicer, the controller for driving the motor 43 may be interchangeably replaced with another juicer. This is designed to replace the control unit and the switch unit 12 including the motor speed control device 80 and the speed selector 85 for controlling the motor 43.

The purpose of these juicers is to provide consumers with a wider range of choices, depending on the cost or purpose of use, and manufacturers can expand the scope of their business by replacing only a few parts and presenting to the consumer another product with a completely different image. Will bring the result.

As shown in FIG. 23, the power supply E2, the safety switch S14, the push switch S15, the motor 143, and the rectifier diode D9 are connected in series.
