DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 and 3, the grinding unit for food garbage according to an embodiment of the present invention includes a food garbage grinding cylinder 10 having an accommodation space 11 in which food garbage is received, A dispersing member 20 rotatably installed in the receiving space 11 of the food waste disposal bin 10 for dispersing the food waste rotatably received by the external force, A fixed knife 30 having both ends fixed to the inner circumferential surface of the food waste grinding barrel 10 in a state of being close to the lower portion of the fixed knife 30, A rotary knife 40 for grinding food waste by interacting with the rotary knife 40 and an outer rim on the inner peripheral surface of the food garbage grinding cylinder 10 in a state of being close to a lower portion of the rotary knife 40, So that the crushed food waste is crushed and the food waste The rotary knife 40 and the rotary shaft 61 key-coupled to the dispersing member 20 are rotated (rotated) in a state of passing through the perforated plate 50 and the fixed knife 30, (Not shown).

The food garbage grinding cylinder 10 is formed in a cylindrical shape and a discharge port 12 through which the food waste accommodated in the accommodation space 11 is discharged to the outside is formed at one side in the lower portion and a fixing projection 13 is formed at the inner peripheral surface . The food waste grinding cylinder 10 is provided with a water injection nozzle 15 for supplying water to the inside thereof. The water spray nozzle 15 supplies water to the food waste grinding cylinder 10 in the process of pulverizing the food waste, so that the food waste can be easily pulverized and the salt contained in the food waste can be discharged. In addition, after the food waste has been crushed, the food waste pulverizing cylinder 10 can be cleaned by spraying water.

The dispersing member 20 is formed in a substantially U-shape with both ends thereof bent upward while being formed into a rectangular shape. A keyhole 21 is formed at a central portion of the dispersing member 20 in which the rotational shaft 61 of the rotating member 60 is keyed. The dispersing member 20 is rotated by the rotational force of the rotary member 60 to prevent the food waste contained in the food waste pulverizing container 10 from being scattered and accumulated.

The fixed knife 30 is formed in the shape of a rectangular plate and has a through hole 31 through which the rotary shaft 61 of the rotary member 60 passes. A fixing groove 32 to be fitted in the fixing groove 13 is formed. The through hole 31 is preferably formed to have an inner diameter larger than the diameter of the rotating shaft 61 so that the inner peripheral surface does not interfere with the outer peripheral surface of the rotating shaft 61. [ The fixed knife 30 is formed in a rectangular shape so that the food waste can pass through and the rotary knife 40 is rotated as the fixing grooves 32 at both ends of the fixed knife 30 are fitted and fixed to the fixing protrusion 13 Interacting causes the food waste to pass through to be cut off.

The rotary knife 40 is projected sideways from the outside of the rotary body 42 and the rotary body 42 where the keyhole 41 is formed at the center and is rotated in contact with the bottom surface of the fixed knife 30, And a rotary blade 43 for cutting food waste passing through the outside of the food waste 30.

The rotary blade 43 has an upper surface 44 contacting the bottom surface of the fixed knife 30 and an upper surface 44 inclined downward from an end of the upper surface 44 to press the cut food waste into the perforated plate 50 The crusher includes a pressing surface 45 and a lower surface 46 extending horizontally from the end of the pressing surface 45 and contacting the perforated plate 50.

Here, the pressing surface 45 of the upper surface 44 is inclined so that the upper end of the rotary blade 43 is sharpened, so that the food waste can be easily cut.

When the rotating blade 43 is rotated in a state where the rotating shaft 61 of the rotating member 60 is key-engaged with the keyhole 41 of the rotating body 42, The upper surface 44 and the lower surface 46 are rotated in contact with each other to cut food waste. At this time, the cut food waste moves downward along the pressing surface 45 and passes through the perforated plate 50 while being pressed at the upper portion of the perforated plate 50. That is, the rotary blade 43 is rotated in a horizontal state between the fixed knife 30 and the perforated plate 50, and is slid with the fixed knife 30 in a scissor-like manner to cut food waste and crush the cut food garbage.

The perforated plate 50 is formed in the shape of a disk so that its rim is close to the inner circumferential surface of the food waste pulverizing vessel 10 and a through hole 51 through which the rotary shaft 61 of the rotary member 60 passes is formed in the central portion, A fixing groove 52 to be fitted in the fixing protrusion 13 of the food garbage disintegration cylinder 10 is formed in the food waste disposal box 10 and a plurality of perforation holes 53 through which the cut food garbage passes are radially dispersed. The through hole 51 is preferably formed to have an inner diameter larger than the diameter of the rotating shaft 61 so that the inner peripheral surface does not interfere with the outer peripheral surface of the rotating shaft 61. [ Accordingly, the food garbage broken by the rotary knife 40 passes through the perforation hole 53 and is accumulated in the lower portion of the food garbage grinding cylinder 10.

The rotary member (60) is constituted by a motor which provides rotational force to rotate the rotary shaft (61) at a high speed. Since the rotary shaft 61 is key-engaged with the keyhole 21 of the dispersing member 20 and the keyhole 41 of the rotary knife 40 in a state of passing through the lower portion of the food waste grinding cylinder 10, The dispersing member 20 and the rotary knife 40 are simultaneously rotated. That is, the food waste is cut while being dispersed, so that it can be easily crushed to a fine size. Here, the rotating shaft 61 is formed with a screw hole 62 so that the bolt is screwed to the upper end thereof. That is, as the bolt is engaged with the screw hole 62 of the rotary shaft 61, the dispersing member 20 and the rotary knife 40 can be detachably fixed.

The present invention is also directed to a food waste disposal apparatus that is disposed under the perforated plate 50 and is key-engaged with the rotary shaft 61 of the rotary member 60 to penetrate the perforated plate 50, And a discharge member (70) for discharging the food waste to the outside of the food waste pulverizing vessel (10).

The discharge member 70 is projected sideways from the outside of the discharge body 72 and the discharge body 72 in which the keyhole 71 is formed at the center and is rotated together with the discharge body 72 to discharge the food waste to the food waste grinding cylinder 72. [ And a discharge wing (73) for discharging the discharge wings (73) to the outside of the casing (10).

The discharge body 72 is formed in the shape of a pointed cone at the top, while an insertion groove 74 is formed at the outer side. That is, the discharge body 72 can prevent food waste from accumulating on the upper part.

The discharge vane 73 is formed with an insertion protrusion 75 which is inserted and fixed in the insertion groove 74 of the discharge body 72 and is sloped downward outward from the upper side of the insertion protrusion 75 side.

Therefore, the food waste passing through the perforated plate 50 is not deposited on the upper portion of the discharge body 72 but is located on one side of the discharge vane 73 without covering the upper end of the discharge vane 73. And, the discharge vane 73 can be detachably mounted to the outside of the discharge body 72, so that the discharge vane 73 can be easily detached and coupled, and can be easily replaced and cleaned.

It is preferable that the discharge vane 73 is made of rubber having elasticity and is formed at a height smaller than the height of the discharge port 12 formed in the food waste pulverizing cylinder 10. The discharge vane 73 is preferably formed to have a length D2 that is longer than the length D1 from the outer circumferential surface of the discharge body 72 to the inner circumferential surface of the food waste grinding cylinder 10 from one end to the other end .

Therefore, when the insertion protrusion 75 is inserted and fixed in the insertion groove 74, the end of the discharge wing 73 is bent while being closely attached to the inner circumferential surface of the food waste grinding cylinder 10. The discharge wings 73 in a bent state are rotated together with the discharge body 72 which is keyed to the rotary shaft 61 of the rotary member 60 in a state of being closely contacted with the inner peripheral surface and the bottom surface of the food waste grinding cylinder 10 The food waste is pushed outward from the center of the food waste grinding cylinder 10. At this time, when the discharge vane 73 is positioned at the discharge port 12 of the food waste grinding cylinder 10, the food waste is strongly bent while being bent, and the food waste is pushed and discharged to the discharge port 12.

4 and 5, the present invention is extended to the upper portion of the food waste grinding cylinder 10 and detachably fixed to the drain hole 2 of the sink 1, And a food garbage collecting member 80 for collecting food garbage while discharging moisture to the outside.

The food waste collecting member 80 is located at a lower portion of the drain hole 2 formed in the sink 1 and has a water discharge hole 81 formed at one side for discharging water discharged through the drain hole 2, A drainage tank 83 in which a food garbage charging hole 82 communicating with the food garbage crushing tank 10 is formed at a lower portion and a drainage tank 83 in a state of being spread over the drainage hole 2 formed in the countertop 1, A fixing ring 84 which is detachably coupled to the drain hole 83 and detachably coupled to the drain hole 83 to fix the drain hole 83 to the sink 1; The food waste inlet hole 82 of the drainage cylinder 83 is opened to permit the introduction of food waste and the food waste inlet hole 82 is closed (Not shown).

The water drainage tube 83 is formed with a female thread 83a on the upper inner circumferential surface thereof and a water inflow hole 83b formed on the other side thereof for introducing water discharged sideways of the sink 1. [ The lower end of the drain canister 83 is connected to the upper portion of the food waste grinding barrel 10 so that the food waste throwing hole 82 is communicated with the accommodation space 11 of the food waste grinding barrel 10. That is, when the lid 86 opens the food waste charging hole 82, the food waste can be received in the food waste grinding cylinder 10.

The fixing ring 84 is formed with an outward flange 87 at an edge of the upper end so as to cover the drain hole 2 of the sink 1 and a male screw 83a screwed to the female thread 83a of the drain tube 83, The acid 84a is formed. An inward flange 88 is formed on the fixing ring 84 so that the screen 85 is caught by the upper edge of the fixing ring 84 and a drain groove 89 is formed on the inner edge of the inward flange 88.

A plurality of perforation holes are formed in the filter screen 85 so as to allow the food waste to be received therein while the upper surface is opened. The perforations 85a are formed on the upper edge of the perforation 85 so as to cover the edge of the retainer ring 84, .

Since the drainage groove 89 is covered by the engagement flange 85a and is not closed even if the engagement flange 85a of the sieve net 85 is caught by the inward flange 88 of the retaining ring 84, So that the waste water can be introduced into the drainage tank 83 through the drainage groove 89. That is, no water remains in the sink 1. [ Particularly, when the food waste containing kimchi or kimchi soup is filtered through the sieve (85) during the washing process in the sink (1), the red pepper powder contained in the kimchi or kimchi soup will block the sieve net (85) The washing water generated in the process of washing the dishes can not be drained through the filtering net 85 and is introduced into the drainpipe 83 through the drainage groove 89. That is, even if the red pepper powder blocks the sieve net 85, the water of the Kimchi and the washing water can flow into the drainage cistern 83 and be discharged to the sewage pipe (not shown) through the water discharge hole 81.

The lid 86 closes the food waste charging hole 82 to prevent moisture from penetrating and cut off the odor of food waste through the food waste charging hole 82. Further, it is preferable that the lid 86 is formed in a hemispherical shape which is convex upward so that moisture is not accumulated. Therefore, even if water is introduced into the drain tank 83 while the food waste charging hole 82 is closed by the lid 86, the water does not flow down from the upper portion of the lid 86, And can be discharged through the water discharge hole 81. In other words, since the drinking water and washing water are not left in the drain pan 83, contamination of the drain pan 83 and generation of odor can be minimized.

In this way, in the state where the lid 86 closes the food waste charging hole 82, the washing water is discarded in the sink 1 together with the food waste generated in the process of cleaning the material to cook the food or in the process of washing the dishes . At this time, the food waste and the washing water are discharged through the drain hole 2 of the sink 1, and the washing water flows into the drainpipe 83 through the filtering net 85 and the food waste is filtered by the filtering net 85 . After the cleansing water is introduced into the drainage tank 83 and the drainage is completed through the water discharge hole 81, the user removes the lid 86 from the drainage tank 83 while removing the filter cloth 85, After the hole 82 is opened, the food waste in the filtering net 85 is put into the food waste charging hole 82. At this time, the food waste put into the food waste charging hole 82 is put into the food waste pulverizing vessel 10. Subsequently, the user rotates the rotary shaft 61 at a high speed by operating the rotary member 60, thereby crushing the food waste put into the food waste grinding cylinder 10. As the food waste is discarded together with the washing water, the washing water is discharged through the filtering net 85 and the food waste is gathered. Therefore, the salt contained in the food waste is also discharged at the time of discharging the washing water. That is, the food waste can be crushed in a state where the salinity is minimized. Finally, the pulverized food waste is discharged to the outside through the discharge port 12 of the food waste pulverizing vessel 10 by the discharge member 70 described above, and can be recycled by collecting in a collecting container (not shown) provided separately .

As described above, according to the present invention, even if the food waste discarded in the sink is washed away together with the washing water, the washing water can be discharged and the food waste alone can be separated and crushed, so that the amount of food waste can be remarkably reduced, It can be recycled as an animal feed or a fertilizer of a crop, so that it can be widely applied to a sink of a home or a restaurant and can be widely used.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is to be understood, therefore, that the above description is intended to be illustrative, and not restrictive, and that the scope of the present invention will be defined by the appended claims rather than the foregoing description, All changes or modifications that come within the scope of the equivalent concept are to be construed as being included within the scope of the present invention.
