Description

Juicer {JUICER}

The present invention relates to a juicer, and more specifically, to a juicer that can easily check the level of juice stored inside the screw in a juicer structure in which the juice separated from the juice residue moves into the inside of the screw.

Recently, as interest in health has increased, the use of juicers that allow individuals to make juice from vegetables, grains, or fruits at home is increasing.

Juicers generally operate by pressing the object to be squeezed with high pressure and squeezing the juice, as in the 'juice juicer' of Registration No. 10-0793852.

A conventional juicer consists of a screw that receives power from a motor inside the juice drum and rotates to crush and compress the juice object, and a mesh drum that is placed between the juice drum and the screw to separate the juice and residue. As it is made up of a mesh filter structure with a large number of fine holes, there is a problem that cleaning is cumbersome.

Accordingly, in recent years, a juicer has been developed that moves the separated juice into the screw and separates it from the residue without a separate mandrel. However, this juicer has a problem in that it cannot check the level of the juice contained inside the screw.

As shown in the drawing, the juicer of the present invention may be configured to include a juice drum 100, a water level display unit 200, and a screw 300.

The juice drum 100 accommodates the screw 300 therein, and serves to crush and compress the juice object by interaction with the screw 300.

The juice drum 100 includes a cylindrical side wall 101 surrounding the side of the juice space and a lower plate 102 disposed at the lower end of the side wall 101 to close the lower part of the juice space.

At the center of the upper surface of the lower plate 102, a waterproof cylinder 103 is formed with a drum hole 103a penetrating in the vertical direction, and on the outer side of the upper surface of the lower plate 102, the waterproof cylinder 103 is concentric with the waterproof cylinder 103. A ring-shaped guide ledge 104, which has a relatively large diameter compared to 103 and rotatably supports the lower end of the screw 300, is formed to protrude.

On the lower outer peripheral surface of the juice drum 100, a juice discharge passage 105 for discharging the juice separated by the juice and a residue discharge port 106 for discharging the remaining residue are arranged to be spaced apart from each other.

In addition, in the area between the waterproof cylinder 103 and the guide jaw 104 on the lower plate 102, there is a juice discharge hole 105a for guiding the juice flowing into the screw 300 to the juice discharge passage 105. ) is formed, and in the area between the guide jaw 104 and the side wall 101 on the lower plate 102, the residue remaining after the juice is extracted between the juice drum 100 and the screw 300 is discharged to the waste discharge port 106. A waste discharge hole 106a is formed to guide the waste.

The waterproof cylinder 103 extends upward from the lower plate 102 of the juice drum 100 and prevents juice located inside the juice drum 100 from leaking out to the outside through the drum hole 103a.

The screw 300 accommodated inside the juice drum 100 is rotatably supported on the guide ledge 104 formed on the lower plate 102 of the juice drum 100, and is connected to the drum hole 103a. It can be coupled to the drive shaft of the driving main body disposed below the juice drum 100, and can rotate by receiving driving force from the driving shaft of the driving main body through this.

The juice object introduced into the juice space of the juice drum 100 is crushed and compressed between the screw 300 and the juice drum 100 by the rotation of the screw 300 disposed in the internal juice space of the juice drum 100. It is separated into juice and residue, and the extracted juice moves to the inside of the screw 300 through a gap (G, see Figure 12) formed on the outer surface of the screw 300, is spatially separated from the residue, and then flows through the juice discharge passage ( It is discharged to the outside of the juice drum 100 through 105), and the residue remaining on the outside of the screw 300 can be discharged to the outside of the juice drum 100 through the residue discharge port 106.

The water level display unit 200 is provided on the outer surface of the juice drum 100 to display the water level of juice accommodated inside the screw 300, and extends from the outer surface of the juice drum 100 in the height direction. A water level chamber 210 that extends and whose lower end communicates with the juice discharge passage 105 to maintain a water level corresponding to the water level of the juice stored in the receiving space 301, the water level of the juice stored in the water level chamber 210 It may include a transparent viewing window 220 constituting at least a portion of the water level chamber 210 so that it can be visually confirmed.

Specifically, the water level chamber 210 may be formed in the form of a groove extending in the height direction from the outer surface of the juice drum 100. For example, the water level chamber 210 is surrounded by a plurality of walls protruding in parallel in one direction from the outer surface of the juice drum 100, and the open front part is closed with a transparent viewing window 220. It can be done in the form of: In addition, in the drawing of this embodiment, the water level chamber 210 is shown as being formed integrally with the juice drum 100, but it is not limited thereto, and is configured to be detachably assembled on the outside of the juice drum 100 if necessary. Alternatively, it may also be possible to be integrally formed inside the transparent viewing window 220.

In addition, a ventilation hole 211 is formed at the top of the water level chamber 210 to communicate with the outside of the water level chamber 210 so that the inside of the water level chamber 210 is not sealed. This ventilation hole 211 is formed in the juice drum ( 100) It is preferable that the internal space and the water level chamber 210 are formed to communicate with each other.

That is, since the water level chamber 210 communicates with the internal space of the juice drum 100 through the ventilation hole 211, even if the pressure increases or decreases while the internal space of the juice drum 100 is sealed. It is possible to maintain a water level corresponding to the water level of the juice stored inside the screw 300.

The transparent viewing window 220 constitutes at least a portion of the water level chamber 210 and is made of a transparent material so that the inside of the water level chamber 210 can be visually confirmed from the outside of the transparent viewing window 220.

In addition, in order to clean the water level chamber 210, the water level chamber 210 is configured to have an open front portion, and the transparent viewing window 220 can open and close the open front portion of the water level chamber 210. It can be configured so that For example, one end of the transparent visible window 220 is rotatably connected to the juice drum 100 to open and close the open front portion of the water level chamber 210 depending on the rotation position, and for this purpose, the juice drum 100 ), a first rotational support shaft 212 is formed on the upper side of the water level chamber 210, and a first rotational support shaft 212 is rotatably coupled to the first rotational support shaft 212 at the upper end of the transparent viewing window 220. A coupling portion 221 may be formed.

The water level display unit 200 further includes a locking unit 230 capable of fixing the position of the transparent visible window 220 in a state in which the open front portion of the water level chamber 210 is closed. can do.

This locking portion 230 may include a locking ring 231 rotatably hinged to the bottom of the transparent viewing window 220 and a pivoting shaft 232 extending to both sides of the locking ring 231.

In addition, a hinge hole 223 is formed at the bottom of the transparent visible window 220, through which the pivot shaft 232 can be rotatably supported, and at the lower side of the water level chamber 210 of the juice drum 100. A locking jaw 213 to which the locking ring 231 can be coupled is formed.

That is, the locking unit 230 rotates the upper end of the transparent viewing window 220 around the first rotational support axis 212 so that the transparent viewing window 220 moves to the open front part of the water level chamber 210. In the closed state, the locking ring 231 located at the bottom of the transparent viewing window 220 is coupled to the locking jaw 213 of the juice drum 100, so that the water level chamber of the transparent viewing window 220 ( The position of the open front part of 210) in a closed state can be fixed.

At this time, the first packing 222 may be interposed between the inner edge of the transparent viewing window 220 and the open front edge of the water level chamber 210. For example, the first packing 222 may be coupled to the inner edge of the transparent viewing window 220 and may be in close contact with the open front edge of the water level chamber 210 to ensure watertightness of the assembly surface. Meanwhile, a packing groove into which the distal end of the first packing 222 can be seated is formed on the open front edge of the water level chamber 210, thereby further improving the adhesion effect.

Meanwhile, in this embodiment, the locking ring 231 of the locking portion 230 is disposed at the bottom of the transparent viewing window 220, and the corresponding locking protrusion 213 is formed on the juice drum 100, for example. However, on the contrary, it would be possible for the locking ring 231 to be disposed on the juice drum 100 and the locking protrusion 213 to be formed on the transparent viewing window 220.

The juice drum 100 extends from the front edge of the water level chamber 210 in a direction parallel to the wall surrounding the water level chamber 210, and the transparent viewing window 220 closes the water level chamber 210. In this state, it may include a first protection portion 214 surrounding the edge of the transparent viewing window 220.

Since the transparent viewing window 220 is protected in a state where the side portion is surrounded by the first protection portion 214 when the front portion of the water level chamber 210 is closed, the position when the water level chamber 210 is closed is It can prevent arbitrary movement due to external forces.

A juice outlet 224 may be formed at the lower end of the transparent viewing window 220 that closes the front part of the water level chamber 210, and the juice outlet 224 can discharge the juice stored in the water level chamber 210 to the outside. ) can be opened and closed by the juice plug 240.

Specifically, the juice discharge port 224 is formed through the lower end of the transparent viewing window 220 to discharge the juice inside the water level chamber 210 to the external space. In addition, for smooth discharge of juice, a discharge guide in the form of a spout extending to a predetermined length may be formed at the bottom of the outer surface of the transparent visible window 220 to surround the juice discharge port 224.

That is, the juice outlet 224 is formed through the transparent viewing window 220 that closes the open front part of the water level chamber 210, and functions as a discharge passage connecting the water level chamber 210 and the external space, and discharges the juice. As it is configured to be opened and closed by the stopper 240, the juice stored in the water level chamber 210 can be discharged to the external space in the open state, and the juice can be stored in the water level chamber 210 in the closed state.

The juice stopper 240 includes an operating lever 241, a sealing valve 242 connected to the operating lever 241 and opening and closing the juice outlet 224 according to the position of the operating lever 241, In order to rotate the juice plug portion 240, a second rotational support shaft 226 is formed on the upper side of the juice discharge port 224 of the transparent visible window 220, and the juice plug portion 240 has the second A second rotational coupling portion 243 may be formed to be rotatably coupled to the rotational support shaft 226.

That is, when the operating lever 241 is lifted upward, the sealing valve 242 is spaced apart from the juice outlet 224, thereby opening the juice outlet 224 and opening the receiving space 301 of the screw 300. And the juice stored in the water level chamber 210 is discharged to the outside through the juice outlet 224, and when the operating lever 241 is pulled down, the sealing valve 242 closes the juice outlet 224 to release the juice. emissions are limited.

Additionally, the transparent visible window 220 may include a second protection portion 225 that protrudes from both sides of the juice outlet 224 and surrounds both sides of the juice plug 240. Since the juice plug portion 240 is protected by being surrounded on both sides by the second protection portion 225 while being rotated in the direction of closing the juice discharge port 224, the juice plug portion 240 is protected from the juice. It is possible to prevent the outlet 224 from arbitrarily rotating toward the opening side.

Meanwhile, the juice plug 240 fixes the position of the sealing valve 242 in a state in which the juice outlet 224 is closed or in a state in which the juice outlet 224 is opened, so that the juice plug 240 can be operated arbitrarily. It may further include a locking mechanism (not shown) that can restrict rotation.

The juicer of this embodiment may further include a supply unit 400 on the upper side of the juice drum 100 that can cut the juice material into small pieces and supply it.

As shown in FIG. 7, the supply unit 400 includes a drum cover 401 detachably assembled on the upper side of the juice drum 100, and a plate surface of the drum cover 401 on the upper side of the drum cover 401. A hopper housing 402 that supplies juice material into the juice drum 100 through an opening formed in the juice drum 100, a hopper cover 403 that opens and closes the upper opening of the hopper housing 402, and a hopper cover 403 that opens and closes the upper opening of the hopper housing 402. A cutting blade 404 that rotates with the screw 300 and cuts the juice material supplied into the hopper housing 402 is disposed on the bottom edge of the hopper cover 403 and is connected to the juice drum 100. It may include a second packing 405 interposed therebetween. Here, the opening formed on the plate surface of the drum cover 401 is formed in a size that can pass a juice material of a size capable of extracting juice within the juice drum 100.

Accordingly, in the case of providing the supply unit 400 as described above, the juice material in the form of a large lump is cut into small pieces by the cutting blade 404 within the hopper housing 402 and an opening is formed on the plate surface of the drum cover 401. Since it can be introduced into the juice drum 100 through , the user can omit the process of cutting the juice material before supplying it to the juicer, thereby further improving convenience of use.

The configuration of the screw 300 and the juice drum 100 for compressing and grinding the juice material is as follows.

A screw thread 330 is formed on the outer peripheral surface of the screw 300, and a plurality of rib jaws are formed to protrude on the inner peripheral surface of the juice drum 100.

The screw thread 330 functions to move the juice material downward, and the rib jaw functions to provide frictional resistance to the screw 300 so that the juice material does not rotate with the screw 300. do.

The juice material introduced into the juice drum 100 through the upper opening of the juice drum 100 is pushed to the lower side by the screw thread 330 and the rib jaw between the inner peripheral surface of the juice drum 100 and the outer peripheral surface of the screw 300. It is compressed and pulverized at the same time as it moves in the direction.

The juice extracted through compression and grinding of the juice material is separated from the residue through a gap (G) formed on the outer peripheral surface of the screw (300) and stored in the internal receiving space (301) of the screw (300) and stored on one side of the lower part of the juice drum (100). It can be discharged through the juice discharge passage 105 formed in the juice, and the residue separated from the juice can be discharged to the outside through the residue discharge port 106 formed on the other side of the lower part of the juice drum 100.

Hereinafter, the grinding structure of the juice drum 100 and the screw 300 will be described in detail.

First, looking at the juice drum 100, a plurality of first rib jaws 110 may be formed to protrude on the inner peripheral surface of the juice drum 100 for compressing and crushing the juice material.

The first rib jaws 110 are arranged to be spaced apart from each other along the inner peripheral surface of the juice drum 100, and each first rib jaw 110 is formed to extend along the longitudinal direction of the juice drum 100 or is formed to extend along the longitudinal direction of the juice drum 100. ) may be formed to extend at a slight incline with respect to the longitudinal direction. The first rib jaw 110 is preferably formed over the entire longitudinal section of the juice drum 100.

The first rib jaw 110 allows the compression and crushing of the juice target to be performed more efficiently by interaction with the screw 300. The first rib ledge 110 acts as a kind of locking ledge and increases friction on the inner peripheral surface of the juice drum 100 to move the juice object smoothly, thereby preventing the juice object from falling below the juice drum 100 and stagnating.

The first rib jaw 110 also generates a large compression force and crushing force on the juice target. The juice object can be pulverized and compressed through interaction with the rotating screw thread 330 while the juice object is supported by the first rib jaw 110.

The height at which the first rib jaw 110 protrudes from the inner peripheral surface of the juice drum 100 may be constant over the entire length, but it gradually decreases from the upper end to the lower end or is at least in the middle of the longitudinal direction of the first rib jaw 110. One or more protruding steps (not shown) may be formed. The protrusion height of the lower end of the first rib jaw 110 may be lower than the protrusion height of the upper end of the first rib jaw 110 based on the step. The position, number, and protrusion height of the steps may vary depending on the formation of the screw 300 and the design conditions of the screw thread 330.

Additionally, a plurality of second rib jaws 120 may be formed on the inner peripheral surface of the juice drum 100.

The second rib jaw 120, like the first rib jaw 110, is arranged to be spaced apart from each other along the inner circumferential surface of the juice drum 100, and is formed to extend along the longitudinal direction of the juice drum 100, or is formed along the juice drum (100). 100) may be formed to extend at a slight incline with respect to the longitudinal direction.

The second rib jaw 120 may be formed to have a shorter length than the first rib jaw 110 in a portion of the longitudinal direction of the juice drum 100, for example, at the lower end of the juice drum 100.

The second rib jaw 120, together with the first rib jaw 110, generates a large compression force and crushing force on the juice target, and the first rib jaw 110 at the upper end of the juice drum 100 The differentially pulverized juice target is further pulverized with the second rib jaw 120 at the lower end of the space of the juice drum 100 to grind the juice target more finely and uniformly.

When the second rib jaw 120 is formed in the middle part of the juice drum 100 rather than the lower part, the juice object is finely pulverized in the middle part of the juice drum 100, and the particle size of the juice object is rapidly reduced, thereby reducing the size of the juice object. At the lower end of the juice drum 100, a problem may occur where the juice drum 100 is not caught on the inner circumferential surface and rotates together with the screw 300. In this case, the juice object is not smoothly transported to the lower part of the juice drum 100 and stagnates, resulting in the inconvenience of having to forcibly press the juice object when attempting to add additional juice objects. However, when the second rib jaw 120 is formed at the lower part of the juice drum 100, the particle size of the juice object changes step by step, so that the juice object is smoothly transported to the lower part of the space of the juice drum 100, and the juice drum ( The juice object transferred to the lower part of 100) can be pulverized more finely.

In addition, when the second rib jaw 120 is formed at the lower end of the juice drum 100, the juice object is smoothly transferred from the upper part of the juice drum 100 to the lower part, and the juice is extracted from the juice drum 100 and the screw 300. The pressure of the target residue gradually increases, and due to this pressure, the juice of the target to be squeezed flows smoothly into the inside of the screw 300 through the gap G formed between the blocking plate 313 and the rib 322 of the screw 300. It may flow in and be discharged to the outside of the juice drum (100).

The first rib jaw 110 and the second rib jaw 120 do not necessarily have to be formed along the longitudinal direction of the juice drum 100. It may be formed in a shape that intersects the spiral screw thread 330 formed on the outer surface of the screw 300 by having a constant inclination in the longitudinal direction.

A plurality of third rib jaws 130 may be further formed on the inner peripheral surface of the juice drum 100. The third rib jaw 130 may be formed between the first rib jaws 110 or between the second rib jaws 120.

The third rib jaw 130 may be formed to extend along the longitudinal direction of the juice drum 100 like the first rib jaw 110 or the second rib jaw 120, and its length is equal to that of the first rib jaw 110. It is shorter than and longer than the second rib jaw 120.

When the third rib jaw 130 is further formed, the number of rib jaws for pulverizing the juice object increases sequentially from the upper end to the lower end in the longitudinal direction of the juice drum 100. In other words, at the top of the juice drum 100, the first rib jaw 110 crushes the juice object, and at the next height, the first rib jaw 110 and the third rib jaw 130 crush the juice object. At the next height, the first rib jaw 110, the second rib jaw 120, and the third rib jaw 130 pulverize the juice target, so that the juice target is gradually pulverized and moves more smoothly to the lower part of the juice drum 100. You can move.

The length, shape, and inclined angle of the first, second, and third rib jaws 110, 120, and 130 can be appropriately designed as needed.

Among the attached drawings, Figures 8 and 9 are perspective views of the screw shown in Figure 2, Figures 10 and 11 are exploded perspective views of the screw shown in Figure 2, and Figure 12 is an explanation of the gap formed in the screw of the juicer of the present invention. It is also a degree.

The screw 300 may be composed of a first module 310 and a second module 320 that are approximately cylindrical in shape.

The first module 310 may be configured to include a first body portion 311 that is formed in a cylindrical shape with a hollow interior. Describing the shape of the first body portion 311 in more detail, it is generally formed in a cylindrical shape as shown. The upper part of the first module 310 may be formed in a shape where the radius gradually decreases toward the top.

The lower end of the first body 311 is open and the upper end is closed, and a screw thread 330 may be formed on the outer surface. Additionally, screw wings 330a may be formed on the outer surface of the upper end. The screw thread 330 may be formed to protrude in the form of a spiral on the outer surface of the first body portion 311. The screw wing portion 330a refers to a portion of the upper end of the screw thread 330, and the screw 300 The protruding height at the top is large, forming spiral wings. The screw wing portion 330a is mainly responsible for the function of cutting the juice material and transporting the juice material downward along the wing surface, and the screw thread 330 with a relatively small protrusion height below the screw wing portion 330a Mainly responsible for the function of crushing and compressing small crushed juice ingredients into smaller sizes to extract juice.

A plurality of screw threads 330 may be formed on the outer surface of the screw 300.

A plurality of slits 312 may be formed in the first body portion 311 in the circumferential direction. The slit 312 may be formed to extend to the bottom of the first body portion 311 and be long in the axial direction. A blocking plate 313 is formed between the two neighboring slits 312. Accordingly, since a plurality of slits 312 are formed along the circumferential direction, a plurality of blocking plates 313 may also be formed along the circumferential direction. The spacing between the slits 312 is preferably formed consistently, but is not necessarily limited thereto.

A lower rotation shaft 316 protruding downward may be formed in the hollow center of the first module 310, and the lower rotation shaft 316 may be combined with a drive shaft (not shown) to receive power.

In addition, an upper rotating shaft 317 protruding upward may be formed at the top of the first module 310, which may be inserted into the shaft hole formed on the lower surface of the supply unit 400 and rotatably supported, and the supply unit 400 It can be connected to the cutting blade 404.

The second module 320 may include a second body portion 321 and a waste discharge guide portion 326.

The second body portion 321 has a cylindrical shape and is inserted into the hollow of the first module 310. Accordingly, the second body portion 321 of the second module 320 has a slightly smaller diameter than the first body portion 311 of the first module 310.

In the second body portion 321, a plurality of ribs 322 may be formed in the shape of a long bar in the axial direction along the circumferential direction. Additionally, in this embodiment, the ribs 322 may be formed to protrude radially outward from the outer surface of the second body portion 321, but are not necessarily limited thereto. For example, the ribs 322 may be formed between the slits 312 like the blocking plate 313 of the first module 310.

Since the ribs 322 are inserted into the slits 312 of the first module 310, they can be formed to be equal to the spacing of the slits 312. At this time, the width of the rib 322 may be slightly smaller than the width of the slit 312.

A juice passage hole 324 may be formed between neighboring ribs 322 to move juice into the screw 300. When the juice passage hole 324 is formed large in the space between neighboring ribs 322, or when the juice passage hole 324 is formed in the entire space between neighboring ribs 322, the second module ( 320 may be formed in a ring-shaped upper end or a disk-shaped second body 321 with a rib 322 extending long downward. That is, depending on the shape of the juice passage hole 324, the second body portion 321 may be formed in a cylindrical shape (ring shape) with a short top and bottom length only at the top of the rib 322, or the top and bottom length of the rib 322. It may be formed into a long cylindrical shape encompassing the entire body.

In addition, the lower ends of the plurality of ribs 322 may be separately supported in a ring shape, but in this embodiment, the lower ends of the ribs 322 are formed to be supported on the upper surface of the waste discharge guide portion 326.

The waste discharge guide portion 326 is formed under the second body portion 321 in a ring shape. The diameter of the waste discharge inducing part 326 may be slightly larger than the diameter of the second main body 321, and the inner peripheral surface of the lower end is the guide jaw 104 formed on the upper surface of the lower plate 102 of the juice drum 100. It can be supported in a rotatable state on the outer peripheral surface.

An outer surface having a predetermined upper and lower length is formed on the outside of the waste discharge guide portion 326, and a protrusion 327 protruding in the radial direction may be formed on the outer surface. As described later, when the first module 310 and the second module 320 are combined, the waste discharge guide portion 326 forms the lower part of the screw 300, and moves downward to the screw 300 during the juice extraction process. The protruding part 327 can push or stir up the waste, thereby promoting smooth discharge of the waste together with the protruding part 328, which will be described later.

If the residue stagnates on the lower side of the screw 300, a lot of load is applied to the screw 300, which may reduce the juice efficiency and cause noise and vibration. In the present invention, the protrusion 327 allows the residue to be discharged more effectively. There is a number.

A plurality of protrusions 327 may be formed along the circumferential direction of the outer surface of the waste discharge guide portion 326 and may be formed to be inclined up and down in the rotation direction of the screw 300. Additionally, it may be formed to extend from the screw thread 330 of the first module 310.

A plurality of protrusions 328 may be formed at the lower end of the protrusion 327 extending in a spiral shape along the circumferential direction. The protrusion 328 may not be extended from the protrusion 327 but may be formed separately. The protrusion 328 has a generally inverted triangle shape as shown, and one surface of the screw 300 in the outer circumferential direction may be formed as an inclined surface. Since the lower end of the debris discharge guide portion 326 is inclined inward with a radius that decreases toward the bottom, the protrusion height of the protrusion 328 may be formed to be relatively larger toward the bottom. As the lower part of the waste discharge guide 326 is inclined inward, a relatively large space for waste accumulation can be secured at the bottom of the waste discharge guide 326 compared to the upper part. At this time, the protrusion 328 performs the function of sweeping the debris accumulated in the space downward.

On the inner surface of the second module 320, a sweep rib 325 is formed that protrudes radially inward in the vertical and longitudinal directions, and functions to agitate the juice inside the screw 300. At this time, as shown, the lower end of the sweep rib 325 protrudes toward the bottom of the juice drum 100 to prevent the juice from settling and maintain a fresh taste. The radial outer side of the lower end of the sweep rib 325 may be spaced apart from the inner side of the second module 320. At this time, by allowing the juice to flow through the space, it is possible to stir the juice through the sweep rib 325 and minimize the juice acting as resistance when the screw 300 rotates.

The first module 310 and the second module 320 can be detachably coupled, and when combined, as shown in FIG. 8, the ribs 322 of the second module 320 are connected to the first module 310. ) is inserted into the slit 312.

As shown in FIG. 12, in the screw 300 of the present invention, the width of the rib 322 is slightly smaller than the width of the slit 312, so when the first module 310 and the second module 320 are combined, A gap G is formed between the rib 322 and the slit 312. In the present design, since the waste discharge guide portion 326 having a predetermined upper and lower thickness is formed in the lower part of the second module 320, the gap G formed by the combination between the slit 312 and the rib 322 is formed by the screw 300. ) Instead of extending to the bottom, it may have a shape that extends only to the top of the waste discharge inducing part 326.

As the screw 300 rotates, the juice generated between the outer surface of the screw 300 and the juice drum 100 moves into the inside of the screw 300 through the gap G and can be spatially separated from the residue. there is. In other words, the screw 300 may serve to compress and pulverize the juice object by interacting with the juice drum 100 and at the same time separate the juice and residue, thereby separating the juice and residue from the juice and residue. The net drum used for separation can be omitted.

And when the first module 310 and the second module 320 of the screw 300 are combined, the gap G formed between the blocking plate 313 and the rib 322 is narrow, but the first module 310 When the and second modules 320 are separated, the gap between the blocking plate 313 of the first module 310 and the ribs 322 of the second module 320 are relatively wide, so that the screw 300 It can be easily cleaned.

When the first module 310 and the second module 320 are combined, the diameter of the waste discharge guide portion 326 is almost the same as the diameter of the first body portion 311 of the first module 310, so that the outer surface is integrated. However, the diameter of the waste discharge guide 326 is slightly larger than the diameter of the first body 311 of the first module 310, so that a small step is formed on the upper surface of the waste discharge guide 326. may be formed.

As shown in the enlarged view of FIG. 10, the inner surface of the lower end of the blocking plate 313 formed between the slits 312 of the first module 310 is slightly bent inward in the radial direction to form a concave shape. It can be. Additionally, a locking protrusion 329 may be formed on the upper surface of the waste discharge inducing portion 326 to protrude so that the lower end of the blocking plate 313 is fastened to and supported on the outer surface. Therefore, when the lower end of the blocking plate 313 is fastened to the outer surface of the stopping protrusion 329, a radial elastic force is applied due to the slightly collapsed shape of the lower end of the blocking plate 313, which causes the blocking plate 313 ) This increases the friction between the lower part and the locking protrusion (329). Therefore, it is possible to prevent the second module 320 from being easily disconnected from the first module 310 due to its own weight.

Although not shown, a magnet (not shown) is placed inside the upper surface of the second main body 321 of the second module 320, and a magnet (not shown) is placed inside the upper surface of the first main body 311 of the first module 310. A magnet or magnetic material with a polarity opposite to that of the magnet placed in the second module 320 may be placed. In this case, when the first module 310 and the second module 320 are coupled, they are not easily separated by magnetic force, so the first module 310 and the second module 320 can remain stably coupled.

One or more helical screw threads 330 may be formed on the outer surface of at least one of the first module 310 and the second module 320.

The screw thread 330 forms a kind of irregularity on the outer surface of the screw 300, so that when the screw 300 rotates, the crushing, compression, and filtration processes for the juice target are performed between the screw 300 and the juice drum 100. It allows this to happen effectively and allows the juice object to move smoothly to the lower part of the juice drum (100).

As described above, the screw thread 330 may be formed in a continuous spiral form in the screw wing portion 330a. Alternatively, it is also possible to form a straight line that intersects the axial direction of the screw 300.

The screw threads 330 are preferably formed on both the outer surfaces of the first module 310 and the second module 320 (more specifically, the outer surfaces of the ribs 322), and are formed on both the first module 310 and the second module 320. When the modules 320 are coupled, the screw threads 330 may be formed in a continuous shape on the outer surfaces of the first module 310 and the second module 320.

That the screw thread 330 is formed continuously on the outer surfaces of the first module 310 and the second module 320 means that the screw thread 330 is formed on the outer surfaces of the first module 310 and the second module 320. ) does not mean that they are physically connected, but rather that they have a generally continuous shape. Accordingly, the screw thread 330 may be broken in some sections in the adjacent portion of the blocking plate 313 and the rib 322.

The screw thread 330 protrudes from the blocking plate 313 and the rib 322 so as to have a shape as continuous as possible on the outer surfaces of the first module 310 and the second module 320. The height can be formed to be almost the same.

At this time, it is preferable that the protrusion 327 of the debris discharge guide portion 326 protrudes more in the radial direction than the screw thread 330 formed at the lower end of the screw 300.

As shown in FIG. 12, the gap G between the slit 312 and the rib 322 may be formed to become wider toward the radial inner side of the screw 300.

If the gap G is formed to become wider toward the radial inner side of the screw 300, the problem of the gap G being blocked by debris or the flow of juice being impeded during the juice extraction process can be prevented.

For example, if the width of the blocking plate 313 is formed to become narrower toward the radial inner side of the screw 300 as shown in Figure 12, when the rib 322 is inserted into the slit 312, the slit 312 and The gap G formed between the ribs 322 becomes larger toward the radial inner side of the screw 300.

Unlike the above example of adjusting the width of the blocking plate 313, the gap G of the screw 300 is adjusted by adjusting the shape of the rib 322 or the shapes of the rib 322 and the blocking plate 313 together. It is also possible to form it to become wider toward the inner radial direction.

Additionally, the gap G may be formed to become narrower toward the lower end of the screw 300 in the longitudinal direction.

Because the pulverized residue is driven to the lower part of the juice drum (100), relatively greater pressure is applied to the lower part of the screw (300), and the object to be squeezed is further pulverized toward the lower part of the juice drum (100), and the size of the pulverized particles is smaller. Therefore, the possibility of debris flowing into the screw 300 through the gap G at the lower end of the screw 300 increases.

Accordingly, the gap G becomes narrower toward the lower end of the screw 300 in the longitudinal direction to prevent the juice target residue from flowing into the screw 300, thereby improving juice extraction efficiency.

If a gap (G) that becomes narrower toward the longitudinal lower part of the screw 300 is applied, for example, in the case of a hard juice target such as carrots, the gap (G) at the lower end of the screw 300 is closed during the compression process. Most of the juice flows into the screw 300. In the case of soft juice objects such as tomatoes, during the compression process, the juice accumulated in the gap (G) at the lower part of the screw (300) rises to the gap (G) at the upper part, and the juice flows into the screw (300).

The gap (G) may be formed to gradually narrow from the top to the bottom of the screw 300, and based on a specific point, the gap (G) at the top is wide and the gap (G) at the bottom is narrow. It can also be formed to change in stages.

The shape of the gap G in the longitudinal direction of the screw 300 can be changed by adjusting the shape of at least one of the blocking plate 313 and the rib 322.

As shown in FIG. 11, a first gap G retaining step 313b is formed protruding on the upper side of the blocking plate 313, and as shown in FIG. 10, on the lower end side of the rib 322. The second gap G maintaining step 322b may be formed to protrude.

The size of the gap (G) between the blocking plate 313 and the ribs 322 changes depending on the rotational force generated as the screw 300 rotates at high speed during juicing or the pressure applied to the outer surface of the screw 300 by the juice target. It may be that the first gap (G) maintaining step 313b and the second gap (G) maintaining step 322b are of the gap (G) formed between the blocking plate 313 and the rib 322 during the juicing process. It serves to keep the size constant.

Hereinafter, the operation of the water level display unit 200, the juice stopper unit 240, and the transparent viewing window 220 of the present invention will be described.

Among the accompanying drawings, Figure 13 is a cross-sectional view illustrating the operation of the water level display unit according to the juicer according to the present invention, Figure 14 is a cross-sectional view explaining the opening operation of the juice stopper according to the juicer according to the present invention, and Figure 15 is a transparent visible window according to the juicer according to the present invention. Figure 16, a cross-sectional view illustrating the opening operation, is a cross-sectional view showing another embodiment of a transparent viewing window according to the juicer of the present invention.

First, as shown in FIG. 13, the juice separated from the residue located between the juice drum 100 and the screw 300 enters the receiving space inside the screw 300 through the gap G of the screw 300. 301). Since the juice is not discharged to the outside of the juice drum 100 when the juice outlet 224 is sealed by the juice stopper 240, the juice is stored in the receiving space 301 as the juice progresses. The level of the juice rises.

At this time, the juice stored in the receiving space 301 of the screw 300 is in a state in which the residue located between the inner peripheral surface of the juice drum 100 and the outer peripheral surface of the screw 300 is compressed under great pressure within a narrow space. Therefore, it may not escape into the space outside the screw 300 through the gap G of the screw 300.

In addition, the waste discharge guiding part 326 located at the lower end of the screw 300 has an inner peripheral surface supported on the outer peripheral surface of the guide ledge 104 formed on the lower plate 102 of the juice drum 100, and the waste discharge guiding part 326 ) As the residue is compressed between the outer circumferential surface and the juice drum 100, the inner circumferential surface of the waste discharge inducing part 326 and the outer circumferential surface of the guide jaw 104 come into strong contact, so the juice stored in the receiving space 301 is connected to the screw 300. It may not escape to the outside of the screw 300 through the coupling surface between the guide jaws 104.

As described above, the juice stored in the receiving space 301 inside the screw 300 has residue located between the juice drum 100 and the screw 300 even if the juice drum 100 and the screw 300 are made of a transparent material. Therefore, the water level cannot be directly checked during the juicing process. Accordingly, in this embodiment, a water level chamber 210 communicating with the receiving space 301 inside the screw 300 is formed on the outer surface of the juice drum 100, and the front part of the water level chamber 210 is made of a transparent material. By finishing with a transparent visible window 220, juice can be extracted even in situations where visibility is impossible due to the juice drum 100 and the screw 300 being made of an opaque material or debris being placed between the juice drum 100 and the screw 300. The level of the juice can be easily checked from the outside of the juice drum (100).

The lower end of the water level chamber 210 is connected to the receiving space 301 through the juice discharge passage 105, so that the juice stored in the receiving space 301 inside the screw 300 flows through the juice discharge passage 105. It can be moved to the water level chamber 210.

In addition, the water level chamber 210 communicates with the internal space of the juice drum 100 through the ventilation hole 211, so when the internal pressure increases or decreases while the internal space of the juice drum 100 is sealed. Even so, the water level corresponding to the water level of the juice stored in the receiving space 301 can be maintained.

A juice outlet 224 is formed on one lower side of the transparent visible window 220 to discharge the squeezed juice. This juice outlet 224 is a juice stopper rotatably supported on the transparent visible window 220. It can be opened and closed by the unit 240.

When the juice plug 240 is rotated to the closed side around the second rotation support axis 226, the sealing valve 242 provided on the juice plug 240 seals the juice outlet 224. It is possible to prevent the juice stored in the receiving space 301 inside the screw 300 from escaping to the outside through the juice outlet 224.

In this state, as shown in FIG. 14, when the lever 241 of the juice plug 240 is lifted upward, the juice plug 240 rotates toward the open side around the second rotation support axis 226. , Accordingly, the sealing valve 242 of the juice plug 240 is spaced apart from the juice outlet 224 and the juice outlet 224 can be opened.

That is, the user can store the desired amount of juice in the juice drum 100 with the juice outlet 224 closed through the juice stopper 240, and if necessary, open the juice outlet 224 and press the screw. The juice stored in the receiving space 301 of 300 can be taken out and consumed.

The transparent visible window 220 that closes the front part of the water level chamber 210 is configured to open and close the water level chamber 210 for convenient cleaning.

The upper end of the transparent viewing window 220 is supported in a rotatable state on the first pivoting support axis 212. When the transparent viewing window 220 closes the water level chamber 210, the transparent viewing window 220 The locking ring 231 of the locking part 230 connected to the lower end of the is engaged with the locking jaw 213 provided at the bottom of the juice drum 100, thereby preventing the transparent viewing window 220 from being opened arbitrarily. .

In this state, as shown in FIG. 15, the locking portion 230, which is rotatably supported around the rotating axis 232 at the bottom of the transparent viewing window 220, is rotated in the unlocking direction to unlock the locking ring 231. ) is separated from the locking jaw 213, the transparent viewing window 220 can unlock the position in which the open front portion of the water level chamber 210 is closed.

That is, since the transparent visible window 220 unlocked by the locking unit 230 is rotatable around the first rotation support axis 212 at the top, the transparent visible window 220 is connected to the water level chamber 210. The front part of the water level chamber 210 can be opened by separating it from the front part of the , and thus the inside of the water level chamber 210 and the inner surface of the transparent viewing window 220 can be easily cleaned.

In addition, the screw 300 is separable from the juice drum 100, and the first module 310 and the second module 320 constituting the screw 300 are also separable, so the screw 300 and the juice are separated. Debris stuck in the gap G between the drum 100 and the first module 310 and the second module 320 can be easily cleaned.

Meanwhile, as shown in FIG. 16, in the present invention, the first rotational coupling portion 221 of the transparent viewing window 220 that opens and closes the open front portion of the water level chamber 210 is formed on the juice drum 100. It can be detachably coupled to the rotational support shaft 212. That is, the first rotational coupling portion 221 of the transparent viewing window 220 may be formed in the form of a ring with a portion of it open so that it can be separated from the first rotational support shaft 212.

In addition, the first rotational coupling portion 221 allows the transparent viewing window 220 to be separated from the first rotational support shaft 212 in a state in which the front part of the water level chamber 210 is opened. It is preferable that the first rotational coupling portion 221 and the first rotational support shaft 212 be coupled to each other when the visibility window 220 closes the open front portion of the water level chamber 210.

According to this configuration, the transparent visible window 220 rotatably coupled to the juice drum 100 can be completely separated from the juice drum 100, thereby further improving the convenience of cleaning the juice drum 100. there is.
