The method of grinding food garbage through the first food garbage disposing unit 200 as described above will now be described. The food garbage into which the food garbage and water are introduced through the drain port of the sink, And can enter the inside of the crushing housing 230.

In this case, the user can drive the first torque generating unit 222 through a switch provided separately. In another embodiment, the first torque generating unit 222 may be operated by fixing the cover 600 by rotating the cover 600 to the fixing unit 100. Hereinafter, for convenience of explanation, the case where the cover 600 is coupled to and fixed to the fixing part 100 will be described in detail with reference to a case where the first torque generating part 222 operates.

When the food waste and water enter the inside of at least one of the fixing part 100 and the crushing housing 230 as described above, the user can attach the cover 600 to the fixing part 100. [ Then, when the cover 600 rotates, the engaging protrusion 110 can move along the engaging projection engaging portion 610.

When the cover 600 rotates, the signal generating unit 710 disposed in the cover 600 may also be rotated. In this case, the sensor unit 720 can sense a signal generated by the signal generator 710. At this time, the signal generating unit 710 may include a magnetic body such as a magnet, and the sensor unit 720 may include a reed switch. Particularly, in this case, when the positions of the sensor unit 720 and the signal generator 710 coincide with each other, a signal can be generated in the sensor unit 720, and these signals can be transmitted to the circuit board 10. When a signal is sensed by the sensor unit 720 as described above, the controller (not shown) provided on the circuit board 10 can determine that the cover 600 has reached the locking position. In this case, the control unit may operate the first rotational force generation unit 222.

When the first rotational force generating unit 222 is operated, the first rotating shaft 223 rotates to rotate the first rotating body 211a and the second rotating body 213a. In this case, the food waste between the blade fixing part 212 and the first rotating body part 211a may be ground by the first inner blade 211b-1 and the first outer blade 211b-2. At this time, if the end of the first outer blade 211b-2 is stepped, the stepped portion of the first outer blade 211b-2 may not interfere with the protrusion 243. If the end of the first outer blade 211b-2 is flattened, the height of the first outer blade 211b-2 may be adjusted so that the end of the first outer blade 211b-2 does not interfere with the protrusion 243, May be lower than the installed height of the second guide plate 243. In this case, the food garbage can be cut or crushed in the space between the first outer blade 211b-2 and the protrusion 243.

The first inner blade 211b-1 and the first outer blade 211b-2 may be arranged in different directions. For example, as an example, the first inner blade 211b-1 may be arranged perpendicular to the diameter of the first rotating body portion 211a. On the other hand, it can be arranged in the radial direction of the first rotating body portion 211a. Further, the first outer blade 211b-2 may be orthogonal to the projection 243. In this case, the food garbage can be cut in various directions through the first inner blade 211b-1, the first outer blade 211b-2, and the protrusion 243. Since the food waste moves toward the fixed ring 240 in accordance with the rotation of the water generated when the first rotating body 211a rotates, the first outer blade 211b-2, which is larger than the first inner blade 211b-1, ), It is possible to effectively grind food waste.

As another example, the first inner blade 211b-1 and the first outer blade 211b-2 may be arranged in the same direction. For example, the first inner blade 211b-1 and the first outer blade 211b-2 may be inclined from the first rotating body portion 211a in the rotating direction of the first rotating body portion 211a Do.

When the first rotating body part 211a rotates as described above, the pulverized food waste can be raised by rotating the water. At this time, the protrusion 243 and the blocking plate 250 can prevent the food waste from rising due to collision with the food waste.

The food waste that has been crushed through at least one of the first inner blade 211b-1, the first outer blade 211b-2, and the protrusion 243 passes through the first rotating body portion 211a together with the water can do. At this time, the pulverized food waste and water can pass through the space between the first edge blade 211c formed on the side surface of the first rotating body part 211a and the stationary ring 240. In this case, according to the rotation of the first rotating body portion 211a, the first edge blade 211c can grind the food waste again.

When the first rotating body 211a rotates as described above, the blade fixing part 212 is fixed to the fixing ring 240 and may not rotate.

The second rotation part 213 can rotate together with the first rotation part 211. In this case, the food garbage crushed in the first edge blade 211c can be moved to the bottom of the crushing housing 230 by being crushed through the second edge blade 213c. At this time, at least one of the second inner blade and the second outer blade protruding to the bottom surface of the crushing housing 230 may crush the food waste floating together with the water stored on the bottom surface of the crushing housing 230.

The pulverized food waste and water may be transferred to the second food garbage disposal unit 300 through the first outlet 231 of the pulverizing housing 230 to be mixed with the microorganism (or the microorganism culture liquid).

Hereinafter, the configuration and operation of the second food waste disposal unit 300 will be described in detail.

FIG. 4 is an exploded perspective view showing the second food waste disposal unit of the food waste disposal apparatus shown in FIG. 1. FIG. 5 is a perspective view showing the shield shown in FIG. 6 is a perspective view showing the stirring part and the food waste removing part shown in FIG.

The second food garbage disposing unit 300 may include a sealing part which is shown in the figure but is not designated by a reference numeral. At this time, the sealing portion can be disposed between the components that are joined to each other to seal the gap.

The connection portion 311 can be connected to a drain of a sink. In particular, the connection portion 311 may be connected to a first outlet (not shown) of the first food garbage disposal unit (not shown). In this case, the pulverized food waste and water can be introduced through the connecting portion 311. At this time, the connection portion 311 is formed to be bent at least once, thereby reducing the speed of water and food waste flowing in. For example, the connection portion 311 may be formed to change the direction of movement of water and food waste at a predetermined angle with respect to the traveling direction of the incoming water.

The connection portion 311 may be connected to the cap portion 330 in various directions. For example, the connection portion 311 may be disposed in the direction shown in FIG. 4 and connected to the cap portion 330. As another example, the connecting portion 311 may be connected to the cap portion 330 in a state of being rotated by 90 degrees from the direction shown in FIG. As another example, the connecting portion 311 may be disposed at a position shifted by 180 degrees from the direction shown in FIG. 4 and connected to the cap portion 330. Therefore, it is possible to install the second food waste disposal unit 300 at various positions based on the first food waste disposal unit (not shown).

The shielding part 320 can guide the water and the food waste supplied from the connection part 311 to the filter part 350. At this time, the shielding part 320 can be coupled to the water storage tank 312, and the driving part 343 and the valve 344 can be seated and fixed. In addition, the shield 320 may be coupled to the cap 330, and the position sensing unit 345 may be inserted and fixed. The shielding part 320 may be provided with a water supply part 342.

The shielding body portion 321 may be formed in a plate shape, and a driving portion 343, a valve 344, a water supply portion 342, and the like may be disposed on an upper surface thereof. In addition, the shielding body portion 321 may be formed with a supply hole 325 through which the water supplied to the connection portion 311 and the food waste move to the filter portion 350. At this time, the supply hole 325 may be disposed inside the guide portion 323. The supply hole 325 is disposed at a portion different from the discharge port of the connection portion 311 so that water and food waste introduced from the connection portion 311 can be prevented from being directly supplied to the supply hole 325. The barrier portion 322 is disposed inside the guide portion 323 and may be disposed around the supply hole 325. [ At this time, the barrier portion 322 may protrude from the upper surface of the shielding body portion 321 toward the cap portion 330. The guide portion 323 is formed to protrude from the shielding body portion 321 toward the cap portion 330, and a space can be formed therein by forming a closed circuit. At this time, the guide part 323 forms a space together with the cap part 330 to form a flow passage for water and food waste. The discharge port of the connection portion 311 may be disposed at one end of the guide portion 323 and the supply hole 325 may be disposed at the other end of the guide portion 323 to be spaced apart from the connection portion 311.

At this time, the portion of the cap portion 330 protruding toward the shielding portion 320 may be disposed at a position different from that of the barrier portion 322. For example, a portion of the cap portion 330 protruding toward the shielding portion 320 may be disposed on the upstream side of the barrier portion 322 with respect to the flow direction of the water. In this case, a channel may be formed between the barrier portion 322 and the cap portion 330 so as to be bent between the portions protruding toward the shielding portion 320. At this time, the water and the food waste move to the supply hole 325 along the flow path between the cap part 330 and the guide part 323, and when the water and the food waste no longer flow through the connection part 311, The space between the cap portion 330 and the guide portion 323 can be shielded by being trapped between the cap portion 330 and the guide portion 323 before reaching the cap portion 330 and the guide portion 323. Particularly, when the user finishes using the sink, water can be filled between the cap portion 330 and the guide portion 323 before reaching the barrier portion 322 by flowing the water last. In this case, the odor generated in the water storage tank 312 and the stirring container 313 can not move to the connection portion 311 along the supply hole 325, so that the odor may not be discharged to the outside.

The driving unit cover 341 may be combined with the shielding unit 320 to shield the water supply unit 342, the driving unit 343, and the valve 344 from the outside. The water supply part 342 may be installed to pass through the shielding body part 321 through the drive part cover 341.

The channel formed by the cap part 330 and the guide part 323 can be bent at least once and is formed so as to descend toward the shielding body part 321 in the vicinity of the supply hole 325 and to rise toward the cap part 330 A part of the water can be stored between the barrier portion 322 and the connection portion 311. [

The water and the food waste falling into the filter unit 350 through the supply hole 325 can be separated from each other. Specifically, the water can be dropped through the holes formed in the filter unit 350, and the food waste can be disposed on the upper surface of the filter unit 350. At this time, the driving unit 343 may be operated to rotate the rotation unit 360. Alternatively, the driving unit 343 may be in a state in which the rotating unit 360 is rotated when the food waste falls during operation. The food waste disposed in the space between the rotating blades 362 can move when the rotating unit 360 rotates. In this case, a certain amount of food waste can be dropped through the opening 351.

During the operation, the signal generator 363 may generate a signal to the outside, and the position sensing unit 345 may sense the signal of the signal generator 363. FIG. Particularly, the position sensing unit 345 can sense the signal of the signal generating unit 363 when the rotating signal generating unit 363 passes under the position sensing unit 345. The driver 343 can continuously operate when the position sensing unit 345 senses a signal. On the other hand, when no signal is detected by the position sensing unit 345 or when a signal is not sensed by the position sensing unit 345 after a lapse of a predetermined time, the operation of the driving unit 343 is stopped, Can be prevented.

On the other hand, the food waste having passed through the opening 351 may fall through the through hole 375 into the agitating vessel 313. The water that has passed through the filter unit 350 can be stored in the discharge trap body 371 and can be guided to the space between the stirring vessel 313 and the water storage tank 312 through the side wall part 372 . Particularly, the water that has passed through the filter unit 350 can not move to the through hole 375 due to the food waste guide 373, and can move to the side wall unit 372.

The water moved to the space between the agitating vessel 313 and the water storage tank 312 moves to the bottom of the water storage tank 312 and can be discharged to the outside through the second outlet 312a.

The food waste dropped into the stirring vessel 313 may be stored in the stirring vessel 313. At this time, some water contained in the food waste may move to the water storage tank 312 through the hole in the bottom of the stirring vessel 313 and may be discharged to the outside through the second outlet 312a.

After the food waste is dropped and stored in the stirring container 313 as described above, the user can open the microorganism input portion 324 through the opening / closing portion 346, and then insert the microorganism through the microorganism input portion 324. [ At this time, the microorganism input portion 324 is formed at a position corresponding to the opening 351 and the through hole 375, so that the microorganism enters the microorganism input portion 324, the opening portion 351 and the through hole 375 sequentially To the stirring vessel 313.

Meanwhile, during the above-mentioned operation, the driving unit 343 operates to rotate the rotating unit 360 and to rotate the stirring unit 380. Concretely, the first agitating blade 383 and the second agitating blade 384 rotate to stir the food waste and the microorganism. In this case, the first protruding edge 383b and the first side protruding edge 383c can rotate the food waste and the microorganism while rotating. In addition, the second protruding edge 384b and the second side protruding edge 384c can rotate the food waste and the microorganism while rotating. Particularly, the second side projecting edge 384c is formed in a curved shape and rotated, so that food waste and microorganisms can be agitated in a wide range of the stirring container 313. In addition, the first agitation blade 383 and the second agitation blade 384 form different angles from each other, so that food waste in various positions can be agitated with microorganisms. At least a part of the first agitating blade 383 and the second agitating blade 384 may be bent so that vibration or the like generated after collision with the food waste is not transmitted to the driving unit 343, It is possible to return to the original state. In addition to the above case, the lower protruding edge 384d may crush the food waste on the bottom surface of the stirring container 313 together with the bottom surface of the stirring container 313 or stir the food waste and the microorganisms. Therefore, the first agitation blade 383 and the second agitation blade 384 can efficiently and rapidly agitate food waste and microorganisms in the agitation vessel 313. The first agitation blade 383 and the second agitation blade 384 are capable of agitating food waste and microorganisms in a wide range within the agitating vessel 313.

The food waste may be adsorbed or caught in at least one of the first agitating blade 383 and the second agitating blade 384 when the agitating part 380 rotates as described above. In this case, an excessive load may be generated in the first agitating blade 383 and the second agitating blade 384, and the driver 343 may be overloaded. At this time, the driving unit 343 may be broken or a fire may occur.

In such a case, the food waste removing unit 390 can remove the food. Specifically, the bending blade 392 and the food waste removing blade 393 may collide with food garbage adsorbed or caught by the first agitation blade 383 and the second agitation blade 384. Particularly, the bending blade 392 can come into contact with the food waste in a part of the first side-surface projecting blade 383c and the second side-surface-projecting blade 384c, and the food garbage removing blade 393 is in contact with the first projecting blade 383b And the second side protruding edge 384c of the food waste. The food waste which has collided as described above may be separated from the first agitating blade 383 and the second agitating blade 384. Therefore, the food waste remover 390 can prevent the drive unit 343 from generating an excessive load.

The food waste stirred with the microorganisms can be partially transferred to the water storage tank 312 through the bottom surface of the agitation vessel 313. Further, another part of the food waste may be decomposed by the microorganism and then moved to the water storage tank 312 through the bottom surface of the agitation vessel 313.

As described above, the by-product of the food waste or the food waste moved to the water storage tank 312 can be discharged to the outside through the second outlet 312a.

Accordingly, the food waste disposal apparatus (not shown) disintegrates the food waste discharged from the above-mentioned sink such as a home or a restaurant into primary and secondary pulverizations, microorganisms are introduced and decomposed and sewage is carried out through the sewerage, But can be easily achieved.

Also, the food garbage disposal apparatus can crush food garbage in various directions, and it is possible to maximize the decomposition speed of food garbage due to microorganisms.
