Especially, in a kitchen such as a home, a large amount of food waste is generated in the process of cooking, washing and cooking many foods, or arranging the remaining food after cooking or after consuming the cooked food.

Since the food waste has a high moisture content, the food waste is heavy and has a large volume, which is not only difficult to treat, but also is easily decayed and generates a large amount of leachate along with the odor, which is the main cause of environmental pollution.

Conventionally, a food processing apparatus has been proposed in which a grinding apparatus is installed in a drain line connected to a drain port of a sink, and the food waste introduced into the drain line is crushed to reduce the volume of final discharged food waste and facilitate the treatment .

However, in the conventional food processing apparatus, a filtering net is provided to remove the moisture of the food waste conveyed between the drain port and the crushing apparatus. The food waste is easily adsorbed to the filter net, and the drainage channel becomes narrow or the filtering net is blocked .

Accordingly, there is a problem that dehydration of the food waste flowing into the pulverizing device is not properly performed and a large amount of moisture is contained. As a result, the food is easily entangled on the cutter of the grinding apparatus, and the grinding of the food is not smoothly performed, so that the cutter is not only excessively rotated but also the motor is easily overloaded due to food sticking to the cutter .

In addition, as the bacterial growth is increased in the foodstuffs crushed by the large amount of water contained in the food waste, there is a problem that the odor is generated and the cleanliness is hindered.

Of course, the split drain pipe 10 may be provided so that the slope part 17 is directly connected to the drain hole 2, but foreign matter having a predetermined length or more introduced together with the wastewater flows into the side of the crushing / dehydrating part 30 It is preferable to connect the bent bent portion 13 to the lower side of the drain hole 2 so as to prevent the bent portion 13 from being damaged.

At this time, the foreign matter having a predetermined length or more means dishes such as spatula and chopsticks which can easily fall into the drain hole (2) during washing.

That is, when the tableware is introduced into the drain hole 2, one end of the tableware contacts the vertically extending portion of the bent portion 13 and the other end of the tableware is hooked while being in contact with the portion connected to the inclined portion 17 And does not flow into the split drain pipe (10).

The first drain hole 11 may be formed on the side of the inclined portion 17 and the second drain hole 12 may be formed on the end of the inclined portion 17. At this time, the cylindrical rotary dewatering unit 20 may be disposed on the inclined portion 17.

In detail, the wastewater flowing into the inclined portion 17 flows to the inside of the cylindrical rotary dewatering unit 20, and moisture in the wastewater flowing into the cylindrical rotation dewatering unit 20 flows into the first drainage hole 11 And the foreign matter may flow into the second drain hole 12 formed at the end of the slope part 17 together with some moisture not discharged.

The cylindrical rotary dewatering unit 20 is rotatably disposed in the split water pipe 10 and a sieve 22 is provided on the outer periphery of the cylindrical drainage dewatering unit 20 so as to filter foreign matter of the water discharged into the first drainage hole 11.

Here, the rotatably disposed means that the cylindrical rotary dewatering unit 20 is inserted into the inclined portion 17 of the split drainage pipe 10 and the inner peripheral surface of the inclined portion 17 and the cylindrical rotating dewatering unit 20 The diameter of the cylindrical rotary dewatering unit 20 is smaller than the diameter of the inclined portion 17 so that a predetermined rotational flow interval is formed between the outer peripheral surfaces of the cylindrical rotary dewatering unit 20.

At this time, it is preferable that the predetermined rotational flow interval is finely set so that foreign matter does not flow at a distance between the outer peripheral surface of the rotary dewatering unit 20 and the inner peripheral surface of the inclined portion 17.

The cylindrical rotary dewatering unit 20 is inserted into the inclined portion 17 and arranged so as to cover the first drain hole 11 with a sieve net 22 provided along the outer periphery thereof. Accordingly, the moisture in the wastewater flowing into the rotary dewatering unit 20 can be discharged to the first drain hole 11, and the foreign matter can be filtered and discharged to the rear of the rotary dewatering unit 20.

2 to 3, the rotary dewatering unit 20 is provided with a blade 21 along its inner periphery to be rotated by the incoming wastewater, It is preferable that the seating protrusion 16 supporting the rear edge of the rotary dewatering unit 20 is stuck.

In detail, the rotary dewatering unit 20 preferably includes a cylindrical hollow frame 23, a sieve 22, and a blade 21. Here, the cylindrical hollow frame 23 is formed with a hollow portion inside, and the front surface 20a and the rear surface 20b are opened to communicate with the hollow portion, and a through portion is formed along the side portion.

The water in the wastewater flowing into the hollow portion is discharged to the first drain hole (11) through the water line (22), and the foreign matter passes through the drainage network (22) And can be discharged to the rear of the rotary dewatering unit 20.

The blades 21 may be disposed along the inner circumference of the front portion of the cylindrical hollow frame 23, but may be disposed obliquely to the inflow direction of the wastewater. At this time, the rotary dewatering unit 20 can be rotated in one direction as the inclined surface of the blade 21 is pressurized by the hydraulic pressure of the introduced wastewater.

A seating protrusion 16, which supports the rear edge of the cylindrical hollow frame 23, may be provided on the rear side of the inclined portion 17. That is, the rotary dewatering unit 20 may be disposed so as to cover the first drain hole 11 as the side of the rotary dewatering unit 20 is inserted forward of the inclined portion 17 and the rear edge thereof is supported by the seating protrusion 16 .

In addition, when the sewage is introduced, the side portion can be fixed and rotated in a state covering the first drain hole 11 without being released to the rear of the inclined portion 17 by water pressure.

The cylindrical rotating dewatering unit 20 is disposed so that the first drain hole 11 communicates with the side where the filtering net 22 is coupled and is rotated by the water pressure when the water is introduced. And can be continuously flowed.

That is, the filtered foreign matter flows together with the rotation of the cylindrical rotary dewatering unit 20 and slides downward in the opposite direction due to its own weight. Accordingly, it is possible to prevent the foreign matter from being adsorbed to the sieve 22, and the fine drain hole of the sieve 22 can be smoothly drained without clogging, so that the dewatering efficiency of the product can be improved.

The rotary dewatering unit 20 is rotated by water pressure to reduce the flow of the wastewater flowing through the centrifugal force into the inside of the rotary dewatering unit 20 and to accelerate the flow through the sieve 22, Water remaining in the foreign matter discharged to the pulverizing / dewatering unit (30) can be minimized by causing the moisture in the pulverizing / dehydrating unit (30) to be discharged to the first drain hole (11) as much as possible.

Accordingly, the adhesion of the foreign matter due to moisture can be reduced, and the adsorption of the foreign matter to the crushing and conveying blade provided in the crushing and dewatering unit 30 can be reduced. That is, it is possible to minimize the cutting force of the pulverized transfer blade due to the adsorption of the foreign matter or the torque loss due to the increase of the weight of the pulverized transfer blade, thereby improving the pulverization efficiency of the product.

At this time, since the rotary dewatering unit 20 can be rotated by water pressure without a separate driving source, the energy efficiency of the product is improved and the productivity of the product can be improved through the compact structure.

1 to 4, the pulverizing and dewatering unit 30 communicates with the second drainage hole 12, and passes through the rotary dewatering unit 20 to crush foreign substances from the separated sewage water.

It is preferable that a dehydrating pipe 15 is provided at a lower portion of the pulverizing and dewatering unit 30 so that moisture of the foreign matter to be ground is discharged and joined to a drainage channel 14 connected to the first drainage hole 11 . The wastewater from which the foreign matter has been separated can flow to the sewage treatment facility in the building through the drainage passage (11).

In detail, the pulverizing / dewatering unit 30 may be provided with a dehydrating hole 37 for discharging residual moisture in the foreign matter. Here, the dehydrating pipe 15 connects the dehydrating pipe 37 and the drainage channel 11.

The pulverizing and dewatering unit 30 may include a waste treatment pipe 32 and a screw rotating unit 36. Here, the waste treatment pipe (32) is arranged to be inclined upward from the front part to the rear part, and a dirt inlet port (33) communicating with the second drain hole (12) is formed in the front part, A dehydrating opening 37 may be formed.

The screw rotation unit 36 may include at least one crushing and conveying blade arranged to rotate inside the waste treatment pipe 32 and spirally arranged along the rotation axis so that the foreign matter may be transported and crushed.

The rotation shaft may be coupled to the driving motor 31 and rotated. At this time, the driving motor 31 may be driven manually according to a button input of a user, and a foreign matter detection sensor may be provided in the waste treatment pipe 32 and may be driven in conjunction with a detection signal of the foreign matter detection sensor Do.

Here, the wastewater passes through the rotary dehydrating section 20, the moisture of the wastewater is discharged to the first drain hole 11, the foreign matter of the wastewater is filtered through the drainage network, and is discharged to the second drain hole 12, Can be introduced into the front portion of the waste treatment pipe (32) through the dirt inlet (33).

The foreign matter introduced into the front portion of the waste treatment pipe 32 is crushed by the crushing and conveying blade and is pushed in the spiral direction according to the rotation of the crushing and conveying blade to be conveyed to the rear side of the waste treatment pipe 32 .

At this time, since the waste water pipe 32 is arranged to be inclined upward from the front part to the rear part, residual water in the foreign matter can flow and be discharged in a direction opposite to the direction of transferring the foreign matter, thereby improving the dewatering efficiency of the product.

In other words, unlike the foreign material which is pushed up to the rear side by the rotation of the crushing and conveying blade, the residual moisture flows downward of the foreign matter by gravity and can be discharged along the sieve of the dehydrating opening 37. Accordingly, the moisture discharged during the compression of the pulverized foreign matter can be smoothly discharged without being reabsorbed, and the dehydration efficiency of the product can be improved.

Meanwhile, it is preferable that the waste treatment pipe 32 is provided with a dust discharge port 34 at a rear portion thereof, and the dust collection box 35 is detachably coupled to the dust discharge port 34. That is, the foreign matter that is crushed by the crushing and conveying blade and is dewatered can be discharged through the dirt outlet 34 and collected in the dirt collecting box 35.

At this time, the dirt collecting box (35) may be provided with a water level sensor for sensing the amount of the collected foreign matter, and a sound output unit for outputting a sound signal according to a sensing signal of the water level sensor. Accordingly, the user can easily grasp whether or not the foreign object in the dirt collecting box 35 is full.

Also, it is possible to separate the dirt collecting box 35 and discharge it easily to the external food garbage discharge box without moving the foreign matter collected in the crushed and dehydrated state to a separate collection container, thereby improving the convenience of the product.

In addition, it is preferable that the waste treatment pipe (35) is provided in a conical shape having a smaller cross sectional area toward the rear side. In detail, the foreign matter is pulverized by the crushing and conveying blade and conveyed backward, and the water can be squeezed and compressed by the inner diameter of the narrowed waste treatment pipe (35).

At this time, the squeezed water is discharged to the sieve side of the dewatering unit (37), and the compressed foreign matter is discharged to the dirt collecting box (35). In this way, the foreign matter is crushed in the waste treatment pipe 35 and compressed along the narrowed pipe to minimize moisture content and volume, so that cleaner and more efficient food waste treatment is possible, It is possible to simplify post-connection processing such as discharging and recycling collected foreign matters.
