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 outside of the lower end of the juice drum 100, a juice outlet 105 for discharging the juice separated by the juice and a residue outlet 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 port 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 residue 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 dregs, and the extracted juice moves to the inside of the screw 300 through a gap (G, see FIG. 12) formed on the outer surface of the screw 300, is spatially separated from the dregs, and then flows through the juice outlet (105). ), and the residue remaining on the outside of the screw 300 may be discharged to the outside of the juice drum 100 through the residue discharge port 106.

The water level display unit 200 extends in the height direction from the outer surface of the juice drum 100 and communicates with the juice outlet 105 to indicate the water level corresponding to the water level of the juice accommodated inside the screw 300. It includes a visible chamber 210 that can be used. At least a portion of the visible chamber 210 may be made of a transparent material so that the level of juice stored therein can be visually confirmed.

Specifically, the visible chamber 210 extends in the height direction from the outer surface of the juice drum 100 and may be surrounded by a plurality of walls. In addition, in the drawing of this embodiment, the visible 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. It would also be possible to do so.

In addition, a ventilation hole 211 is formed at the top of the thorn chamber 210 to communicate with the outside of the thorn chamber 210 so that the inside of the thorn 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 visible chamber 210 are formed to communicate with each other.

That is, since the visible chamber 210 communicates with the internal space of the juice drum 100 through the ventilation hole 211, even when 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 visible chamber 210 has a bottom that is open for cleaning, and the opening of the visible chamber 210 can be opened and closed using the chamber cover 220.

For example, one end of the chamber cover 220 is rotatably connected to the juice drum 100 to open and close the opening of the thorn chamber 210 according to the rotation position. For this, one end of the chamber cover 220 A rotational support shaft 221 is formed in the portion, and a rotational coupling portion 212 rotatably coupled to the rotational support shaft 221 is formed on one side of the opening of the thorn chamber 210 of the juice drum 100. You can.

At this time, the first packing 222 may be interposed between the inner edge of the chamber cover 220 and the edge of the opening of the visible chamber 210. For example, the first packing 222 may be coupled to the inner edge of the chamber cover 220 and may be in close contact with the edge of the opening of the visible chamber 210 to ensure watertightness. 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 visible chamber 210, thereby further improving the adhesion effect.

Meanwhile, although not shown in the drawing, it would be desirable to provide a locking part that can fix the position of the chamber cover 220 when the opening of the visible chamber 210 is closed using the chamber cover 220. .

The juice outlet 105 may be formed in the chamber cover 220, and the juice outlet 105 may be opened and closed by the juice plug 230.

Specifically, the juice outlet 105 is formed through the chamber cover 220 to discharge the juice inside the thorn chamber 210 to the external space, and may be extended to a predetermined length for smooth discharge of the juice. .

The juice stopper 230 supports an operating lever 231, a sealing valve 232 that opens and closes the juice outlet 105 according to the position movement of the operating lever 231, and the sealing valve 232. It includes a discharge cover 233 disposed below the juice discharge port 105 while the operating lever 231 is rotated to the closed side.

Specifically, the operating lever 231 is disposed on the front part of the thorn chamber 210, the discharge cover 233 is disposed below the juice discharge port 105, and the operating lever 231 and the sealing valve 232 ) is formed in a form where one end is connected to each other. The portion where the operating lever 231 and the discharge cover 233 are connected is rotatably hinged to the hinge portion 223 provided on one side of the juice discharge port 105 of the chamber cover 220 and can be rotated to the open or closed side. It is preferable that the closed side is elastically supported by an elastic body not shown.

When the operating lever 231 of the juice plug 230 is rotated to the closed side, the discharge cover 233 is in close contact with the bottom of the chamber cover 220 and further rotation is limited, so that the juice plug 230 The rotational position of the closed side can be guided.

In addition, a stopper 224 is formed on the chamber cover 220 to closely support the end of the discharge cover 233 when the operation lever 231 is rotated to the open side. Accordingly, in a state in which the operating lever 231 of the juice plug 230 is rotated to the open side, the end of the discharge cover 233 is in close contact with the stopper 224, and further rotation is limited, so that the juice plug portion ( The rotational position of the open side of 230) can be guided.

As the operating lever 231 of the juice stopper 230 rotates to the open side, the discharge cover 233 rotates around the hinge portion 223 together with the operating lever 231 to open the juice outlet 105. It is arranged obliquely at the bottom. At this time, the discharge cover 233 may function as a guide to guide the discharge direction of the juice discharged through the juice discharge port 105.

In addition, guide ribs 234 are formed protruding on both sides of the surface of the discharge cover 233 facing the chamber cover 220, so that the juice guided through the discharge cover 233 is discharged cover 233. You can prevent it from flowing down on both sides.

In addition, the chamber cover 220 is formed with a rib receiving groove 225 into which the guide rib 234 can be inserted while the discharge cover 233 is in close contact with the chamber cover 220. That is, when the juice plug portion 230 is rotated to the closed side, the guide rib 234 of the discharge cover 233 engages with the rib receiving groove 225 of the chamber cover 220, so that the The position of the discharge cover 233 can be maintained stably.

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 outlet 105 formed in the juice, and the residue separated from the juice can be discharged to the outside through the residue outlet 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.

The juicer of this embodiment may further include an internal drum 140 detachably assembled inside the juice drum 100, and the first rib jaw 110 and the second rib jaw 110 are formed on the inner peripheral surface of the internal drum 140. The rib jaw 120 and the third rib jaw 130 can be formed.

In this way, when the internal drum 140 is detachably assembled to the juice drum 100, not only is it easy to clean, but the durability of the product can be further improved by making the internal drum 140 made of a material with excellent wear resistance.

Meanwhile, in this embodiment, the juice drum 100 is described as additionally provided with an internal drum 140, but the first, second, and third rib jaws 110 and 120 are installed on the inner surface of the juice drum 100. , 130) is also possible to form integrally.

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 a description of the gap formed in the screw of the juicer of the present invention. It's a degree.

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 debris 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 waste discharge guide portion 326 is inclined inward so that the radius 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 guiding part 326 is inclined inward, a relatively large space for waste accumulation can be secured at the lower side of the waste discharge guiding part 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. Therefore, 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.

Below, the operation of the water level display unit 200 of the present invention will be described.

Among the accompanying drawings, Figure 13 is a cross-sectional view showing the operation of the visible chamber according to the juicer according to the present invention, Figures 14 and 15 are diagrams showing the operation of the juice plug according to the juicer according to the present invention, and Figure 16 is a view showing the operation of the juice plug according to the juicer according to the present invention. This is a drawing showing the operation.

First, as shown in Figure 13, the juice separated from the residue located between the juice drum 100 and the screw 300 is inside the screw 300 through the gap (G, see Figure 12) of the screw 300. flows into the receiving space 301, and since the juice is not discharged to the outside of the juice drum 100 when the juice outlet 105 is sealed by the juice stopper 230, as the juice progresses, the receiving space 301 The level of the extracted juice stored within increases.

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 thorn chamber 210 communicating with the receiving space 301 inside the screw 300 is formed on the outer surface of the juice drum 100, and at least a part of the thorn chamber 210 is made of a transparent material. By configuring the juice drum 100 and the screw 300 to be made of an opaque material or in a situation where visibility is impossible due to debris being placed between the juice drum 100 and the screw 300, the water level of the juice can be maintained. It can be easily confirmed from the outside of the drum 100.

Since the lower end of this thorn chamber 210 is connected to the receiving space 301 through the juice discharge hole 105a, the juice stored in the receiving space 301 inside the screw 300 flows through the juice discharge hole 105a. You can move to the visible chamber (210).

In addition, the visible 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.

The lower opening of the thorn chamber 210 is closed by a chamber cover 220, and a juice outlet 105 through which juice can be discharged is formed in the chamber cover 220, and the juice outlet 105 is formed in the chamber cover 220. It can be opened and closed by the juice stopper 230 rotatably supported on the chamber cover 220.

When the juice stopper 230 is rotated to the closed side around the hinge part 223, the sealing valve 232 provided on the juice stopper 230 seals the juice discharge port 105, so that the screw 300 It is possible to prevent juice stored in the internal receiving space 301 from escaping to the outside through the juice outlet 105.

In this state, as shown in FIG. 14, when the lever 231 of the juice plug 230 is pulled down, the juice plug 230 rotates toward the open side around the hinge portion 223, and accordingly As the discharge cover 233 rotates with the lever 231 and is spaced apart from the lower side of the juice discharge port 105, the sealing valve 232 supported on the discharge cover 233 is spaced away from the juice discharge port 105 and is spaced apart from the juice discharge port 105. Open (105).

In other words, the user can store the desired amount of juice in the juice drum 100 with the juice outlet 105 closed through the juice stopper 230, and if necessary, open the juice outlet 105 and press the screw. The juice stored in the receiving space 301 of 300 can be taken out and consumed.

Here, in a state in which the juice plug portion 230 rotating around the hinge portion 223 closes the juice discharge port 105 as shown in (a) of FIG. 15, that is, in a state rotated toward the closed side, the discharge cover 233 Since additional rotation is restricted while being in close contact with the bottom of the chamber cover 220, the closed rotation position of the juice plug portion 230 can be guided. In addition, when the juice stopper 230 opens the juice discharge port 105 as shown in (b) of FIG. 15, one end of the discharge cover 233 is in close contact with the stopper 224 provided on the chamber cover 220 side. As additional rotation is limited, the rotational position of the open side of the juice stopper 230 can be guided.

The chamber cover 220 that closes the lower opening of the visible chamber 210 is configured to open and close the visible chamber 210 for convenient cleaning. Accordingly, as shown in FIG. 16, the lower opening of the visible chamber 210 can be opened by rotating the visible chamber 210 around the rotational support axis 221 to separate it from the lower opening of the visible chamber 210. Accordingly, the interior of the visible chamber 210 and the inner surface of the chamber cover 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.

Among the attached drawings, Figures 17 and 18 are exploded perspective views of the juicer according to the second embodiment of the present invention, Figures 19 and 20 are cross-sectional views showing the open and closed state of the juice cap portion of the juicer according to the second embodiment of the present invention, Figure 21 is a diagram showing the opening and closing operation of the juice stopper of the juicer according to the second embodiment of the present invention.

In the juicer according to the second embodiment of the present invention as shown in the drawing, the juice stopper portion 230' that opens and closes the juice outlet 105 is configured in a sliding manner, unlike the rotating method in the first embodiment. There is a difference from the first embodiment.

Specifically, the juice stopper 230' is a discharge cover 233' movably supported with respect to the chamber cover 220' so that the discharge port 236 formed on the plate surface selectively communicates with the juice discharge port 105. Includes.

That is, when the discharge port 236 formed on the plate surface of the discharge cover 233' is located below the juice discharge port 105 and communicates with the juice discharge port 105, the juice discharge port 105 and the discharge port 236 Juice can be discharged through this.

In addition, when the plate surface of the discharge cover 233' closes the lower part of the juice discharge port 105, the discharge of juice through the juice discharge port 105 may be restricted.

For this purpose, the discharge cover 233' is assembled to the chamber cover 220', and the upper surface facing the chamber cover 220' and the juice outlet 105 are formed on the upper surface of the chamber cover 220'. It is desirable to keep the bottom surfaces in close contact with each other. In addition, in a state where the discharge cover 233' is moved to a position that closes the juice discharge port 105, the juice discharge port 105 is located at a position corresponding to the juice discharge port 105 of the discharge cover 233'. It would also be possible to place a sealing valve that can seal the .

A pair of rail grooves 225 are formed on both sides of the chamber cover 220' in a direction parallel to the moving direction of the discharge cover 233', and on both sides of the discharge cover 233', the rail grooves ( A slide protrusion 235 that can slide is formed within 225).

That is, as shown in FIG. 19, when the user pushes the discharge cover 233', the discharge port 236 formed on the plate surface of the discharge cover 220' is misaligned with the juice discharge port 105, thereby discharging the discharge cover 233'. The plate surface can close the juice discharge port 105, and as shown in FIG. 20, when the discharge cover 233' is pulled, the discharge port 236 formed on the plate surface of the discharge cover 233' is connected to the juice discharge port 105. By communicating, the juice discharge port 105 can be opened.

Here, as shown in Figures 19 and 21 (a), when the user pushes the discharge cover 233' and the discharge port 236 is completely separated from the juice discharge port 105, the slide protrusion 235 of the discharge cover 233' ) is supported on one end of the rail groove 225 to limit further movement, and the discharge port 236 is the juice discharge port ( 105), the slide protrusion 235 of the discharge cover 233' is supported on the other end of the rail groove 225, so further movement may be restricted.

When the juice discharge port 105 is opened by sliding the discharge cover 233' as described above, the area in communication between the discharge port 236 and the juice discharge port 105 increases while the discharge cover 233' moves toward the opening side. Since it increases gradually, it is possible to prevent the juice stored in the juicer from being suddenly discharged.
