Description

[0001] The present invention relates to an upper driving type juice extractor,

The present invention relates to an upper driven type nutrient solution having an automatic elevating portion for automatically elevating a juice portion by using a motor.

As a conventional upper driven centrifuge, there is proposed, for example, as disclosed in Patent Documents 1 and 2, which are filed by the present applicant.

The upper driven centrifuge of the patent literature comprises a juice extracting unit for separating juice and debris from each other; A driving part for driving the juice part; A main body including a drive mount main body on which the drive unit is mounted on an upper part thereof and a cash slot main body having a carry slot formed therein so that the pocket can be carried forward and backward; And a lift portion for lifting the juice portion with respect to the driving portion.

In Patent Document 1, the juice outlet and the residue outlet are formed on the lower surface of the housing of the juice portion, and both the receiving cups are housed in the lower portion of the main body.

In Patent Document 2, a juice outlet is formed on the lower surface of the housing of the juice portion, and a residue outlet is formed on the outer surface.

In these patent documents, since the juice outlet is formed on the lower surface of the juice portion, the cup must be housed inside the main body, so that it can not be seen from the outside and can overflow.

In addition, since the lifting and lowering portions of Patent Documents 1 and 2 are manually operated in which the lifting projection or the ring lever is turned, there is a problem that the user, especially the housewife, is somewhat difficult.

Also, there is a problem that the user has to detect how much the lifting portion of the manual type is raised and how much.

In Patent Documents 1 and 2, since the upper side of the receptacle groove and the upper surface of the juice portion are separated from each other, when the juice enters between the upper and lower portions of the juice receptacle,

In addition, since the upper driving-type raw-fluid machine is pressed and rotated while the screw is being pressed, the resistance (reaction force) against the juice is applied up and down, and the durability of the main body of the plastic material tends to increase.

Also, since the material inlet port is fixed to the lid or the like, it is inconvenient to clean the inside of the material inlet port when the lid comes along.

In addition, since the lower end of the material inlet of Patent Document 1 is not fitted with the upper surface of the juice portion, the juice can be inserted into the main body through the space between the lower end of the material inlet and the upper surface of the juice portion when the juice splashes in all directions.

Further, since the motor is usually a DC motor and the rpm is fixed, the speed can not be controlled in multiple stages such as one stage (vegetable) or two stages (fruit) depending on the juice (for example, vegetables or fruits).

Further, when the drive shaft of the motor and the driven shaft of the screw are not in the engaged positions, the drive shaft or the driven shaft must be rotated manually because of the upper drive type.

In addition, when the liquid overflows to the center of the lid, if the liquid flows down behind the upper surface of the lid, there is a problem that the body is also dirty and the cleaning range is wide and troublesome.

The second-first gear 333b meshes with the first-second gear 335a.

The third reduction gear unit 330c includes a third rotation shaft 331c and a third gear 333c provided on the third rotation shaft 331c.

The third gear 333c is a gear having a larger spinning wheel than the fourth gear 335d described later.

And the third gear 333c meshes with the second -2 gear 335b.

The fourth reduction gear unit 330d is provided with a fourth rotation shaft 331 and a fourth gear 335d provided on the fourth rotation shaft 331. [

The fourth gear 335d meshes with the third gear 333c.

The fourth rotary shaft 331 of the reduction gear unit 330 is an output rotary shaft, and a drive shaft 320 is provided at a lower end thereof.

The drive shaft 320 is formed with protrusions on its inner circumferential surface, such as a tooth, at predetermined intervals.

The driving unit 310 and the reduction gear unit 330 are mounted on the casing 200.

The casing 200 includes a lower casing 210 and an upper casing 230, as shown in FIG.

The lower casing 210 is formed with a support plate 311 for supporting the motorized portion of the motor 310 and a mounting casing 213 on which the rotary shaft 311 and the reduction gear unit 330 are mounted.

The upper casing 230 serves as a cover for covering the upper portion of the mounting casing 213.

Bearings or bushes B are provided at both ends of the first rotation shaft 330a, the second rotation shaft 330b, the third rotation shaft 330c and the output rotation shaft 3331. [

The casing 200 is formed with a groove 201 in which a bearing or a bush B is installed and grooves 203 in which the reduction gears are housed.

That is, the grooves 201 and 203 of the casing 200 are formed in a circular shape.

The lower casing 210 of the reduction gear unit 330 is fastened to the upper portion of the upper frame 1110a.

The motor 310 is coupled to one side of the reduction gear unit 330 and supported in the form of a cantilever.

In particular, the motor 310 is preferably implemented as a BL (brushless) motor capable of speed control depending on the material (depending on the degree of rigidity of the material).

For example, a speed selection switch such as a first stage (light employed), a second stage (for fruits), and a reverse rotation is provided to drive and control the motor 310 through the control unit 900, So that the juice efficiency, taste and energy efficiency are excellent. If you use a motor with the same number of revolutions, the vegetables will be the number of revolutions that the juice is rotated well and the fruit will be the less number of revolutions. If the fruit is the juice that rotates well, the vegetable will pressure more than necessary, .

Of course, it is preferable to provide a control unit 900 that can measure the juicing power in the juicing process of the material and automatically select the rotational speed of the motor 310 according to the material.

As shown in FIGS. 13 to 15, the juice extractor 500 includes a housing 510 having a juice outlet 511 and a residue outlet 513, a lid 530 coupled to an upper surface of the housing 510, And the upper end of the screw 550 is rotatably supported by the through hole 533 of the lid 530 and the screw 550 is screwed into the housing 510. The lower end of the screw 550 is supported by the groove 515 at the bottom of the housing 510, And a rotating brush 590 rotatably interposed between the housing 510 and the net drum 570. The rotating drum 590 is rotatably disposed between the housing 510 and the net drum 570. [

At the upper end of the screw 550, a driven shaft 551 engaged with the drive shaft 320 is formed. The driven shaft 551 is formed with projections at predetermined intervals so as to be engaged with the drive shaft 320. [

As in this embodiment, the drive shaft 320 and the driven shaft 551 may be engaged with each other in a tooth shape, or may be engaged with a socket and a wrench type, that is, a polygonal shape.

The lid 530 is formed with a material supply communication hole 531 which is inserted into the material input port 111 so as to communicate therewith.

The driven shaft 551 is engaged with the driving shaft 320 and the material feeding communication hole 531 is inserted into the material input port 111. [

More specifically, a protruding wall protruding upward is formed around the material introducing communication hole 531, and the protruding wall is inserted into the material input port 111. [

Particularly, as shown in Fig. 3, the material inlet communication hole 531 is inserted between the lower end of the material inlet 111 and the lower end of the material inlet 113 for attachment, thereby reliably preventing the introduced material from leaking to the outside.

The lid 530 has a lid grip 532 protruding outwardly, which is easy to grasp when it is fastened or disassembled.

The rotary brush 590 is rotated as follows.

When the screw 550 is rotated, a tooth 553 formed at the lower end of the screw 550 is engaged with the gear 517 provided at the bottom of the housing 510 and rotated.

When the gear 517 is rotated, the gear 517 is engaged with the tooth 591 formed on the lower edge of the rotary brush 590 and rotated.

The rotation of the screw 550 is transmitted to the rotary brush 590 via the gear 517 because the gear 517 and the gear 591 are engaged with each other, .

On the other hand, the driven shaft 551 and the drive shaft 320 are interrupted as the lifting and lowering unit 700 is lifted and lowered like a jaw clutch.

Therefore, if the position where the knot is not correctly positioned, the motor 710 of the lift unit 700, which will be described later, is overloaded and the user must manually rotate the driven shaft 551 or the drive shaft 320 manually.

If the driven shaft 551 does not engage with the drive shaft 320 when the juice extractor 500 is lifted, the control unit 900 lowers the juice extractor 500 and rotates the drive shaft 320 slightly by the rotation of the motor 310 And rotates to control the engagement position.

That is, the lift unit 700 may further include an up limit switch 600 and a down limit switch 610 for applying an input signal to the controller 900.

Therefore, if the driven shaft 551 is not engaged with the driving shaft 320, the up limit switch 600 is in the OFF state. If the time of the OFF state reaches the set time, the controller 900 controls the up / And drives and controls the motor 310 of the driving unit 300 after driving the motor 710 to be lowered.

6 and 13, a guide protrusion 430 is formed on the left and right sides of the upper surface of the lid 530 and a guide protrusion 430 is formed on the bottom surface of the upper cover of the front groove 120, A groove 410 is formed.

Accordingly, it can be confirmed that the lid 530 is properly closed in the housing 510, and also serves to hold the lid 530 when the screw 550 is rotated.

18A to 21, the elevating part 700 includes a lifting motor 710, a seating part 730 on which the juice part 500 is mounted, a cam part 750 for lifting and lowering the seating part 730, And a power transmitting portion 770 for transmitting the power of the elevating motor 710 to the cam portion 750.

The elevating motor 750 is a DC motor driven and controlled by the control unit 900 and mounted on the bottom surface of the lower frame 1110b.

The power transmitting portion 770 is made up of a planetary gear 790 that receives the power of the elevating motor 710.

19 and 20, the planetary gear 790 includes a sun gear 791, a planetary pinion 793 engaged with the sun gear 791, a ring gear 795 as an internal gear engaged with the planetary pinion 793, ).

The sun gear 791 is rotatably installed on the output shaft 721 of the reduction gear 720 that receives the power of the lift motor 750 and transmits the power to the sun gear.

The reduction gear 720 is also provided on the bottom surface of the lower frame 1110b like the elevating motor 710. [

The output shaft 721 is exposed upward through the fourth through hole 1117 of the lower frame 1110b.

The planetary pinion 793 is rotatably mounted on the pin 1119 of the lower frame 1110b.

A through hole 796 is formed in the center of the upper plate 795a so that the output shaft 721 can be inserted into the ring gear 795.

A groove is formed in the bottom surface of the upper plate 795a of the ring gear 795 so as to fit the pin 1119 to prevent the planetary gear 790 from being pulled up.

The cam portion 750 includes a cam 751 formed on the lower surface of the seating portion 730 and a roll portion 753 provided on the outer peripheral surface of the ring gear 795 and rotated along the cam 751 in accordance with the rotation of the ring gear 795 ).

As shown in Figs. 18B and 21, the cam 751 is provided with a descending portion 751a, a rising portion 751c located below the descending portion 751a, and a rising portion 751c from the descending portion 751a And an inclined portion 751b.

Accordingly, when the ring gear 795 rotates in the direction of the solid line as shown in Fig. 21, the roll portion 753 pushes up the raised portion 751c, and the seat portion 730 rises.

Conversely, when the ring gear 795 rotates in the direction of the dotted line, if the roll part 753 rolls along the rolling part 751c and the inclined part 751b and falls on the descending part 751a, the seat part 730 descends.

The ring gear 795 is provided with an operating piece 630 for operating the up limit switch 600 and the down limit switch 610 as shown in Fig.

The rising limit switch 600 and the falling limit switch 610 are electrically connected to the control unit 900.

When the operating piece 630 is turned on by pressing the up limit switch 600, the juice part 500 stops rising, and when the operating part 630 is pressed down by the down limit switch 610, the juice part 500 stops descending.

The seating portion 730 is mainly composed of a cam forming portion 730a having a cam 751 and a seating cover portion 730b coupled to the upper surface of the cam forming portion 730a.

A groove 731 for rotatably inserting the upper end of the output shaft 721 is formed at the center of the cam forming portion 730a.

A column 733 inserted into the downward projecting pipe 1121 of the lower frame 1110b extends downward at the edge of the cam forming portion 730a.

The column 733 is partially exposed downward from the downward projecting pipe 1121. [

Further, it is preferable to further provide a spring 740 that applies elastic force to the main body 100 to pull the seat portion 730 downward.

The spring 740 is for pulling the seat portion 730 to the lowered position and is inserted into the lower protrusion pipe 1121 and then the bolt 745 is fastened to the lower end of the column 733, A spring 740 is supported between the bottom surface and the head of the bolt 745.

Therefore, since the spring 740 pulls the bolt 745 downward relative to the frame 1110, the seat portion 730 is subjected to the elastic force to the lowered position, thereby helping to further induce the lowering force. (When the seat part is lifted, there is no problem for the rise because the roll force causes the cam to support the cam, but when the drop is dependent on the gravity, the spring is constructed so as not to fall down quickly.

The seating cover portion 730b is fitted to the camshaft-like portion 730a and has a seating position groove 735 formed on the upper surface thereof.

In the seating position groove 735, a seating position projection 737 formed on the bottom surface of the housing 510 of FIG. 15 is placed.

In addition, on the bottom surface of the housing 510, a debris discharge control packing 520 inserted into the inlet of the debris discharge port 513 is inserted.

An interference protruding piece 525 is formed on the upper surface of the seating cover portion 730b to cause interference when the residual drainage control packing 520 is released.

The residue discharge control packing 520 controls the discharge rate by being pushed downward at the entrance of the residue discharge port 513 according to the amount of the residue as shown in FIG.

If the residue discharge control packing 520 is seated in the missing state, the residue is leaked. Therefore, if the residue discharge control packing 520 is placed on the interference projection piece 525, the juice receptacle 500 is not properly seated, It can be judged.

On the other hand, as shown in Figs. 13 and 14, it is preferable that a shoulder 540 protruding upward is formed around the upper surface of the front side of the lid 530.

The jaw 540 is constituted by a first jaw 541 provided at a part of the circumference as shown in Fig. 13 and a second jaw 543 spaced from both ends of the first jaw 541.

A drainage passage 545 is formed as a groove with a gap between the first jaw 541 and the second jaw 543.

The first jaw 541 and the second jaw 543 block the gap T between the upper side of the front groove 120 and the upper surface of the lid 530 before the juice 500 rises , And prevents a finger or the like from being raised in a state sandwiched therebetween.

In addition, the edge of the lid 530 is composed of an oblique oblique surface 547 which is inclined toward the outside from the top to the bottom.

The beveled surface 547 functions to easily ride down when the juice 500 rises even if the finger is hooked on the jaw 540.

The jaw 540 is inserted into the jaw fitting groove 560 formed on the upper side of the front groove 120. When the jaw 530 is lifted up, the drainage passage 545 is slightly exposed as shown in Fig. 17B.

On the upper surface of the lid 530, a partition plate 580 partitioning the front and rear parts may be formed upward.

The through hole 533 of the lid 530 is disposed between the partition plate 580 and the first jaw 541 exactly at the jaw 540.

Both ends of the partition plate 580 and both ends of the second step 543 are connected to each other and a drainage passage 545 is formed. The partition plate 580 serves to guide the water into the drain passage 545 in a V-shape.

Therefore, the partition plate 580 and the first jaw 541 function as a dam to drain the liquid leaked through the through hole 533 only by the drainage passage 545, so that the partition plate 580 and the first jaw 541 can be prevented from flowing into the main body 100, Thereby facilitating cleaning.

The partition plate 580 is also inserted into a plate fitting groove 585 formed on the upper side of the front groove 120.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
