The housing 10 may include a crush plate 11 provided on the inner side thereof. A more detailed description of the crush plate 11 will be described later.

The inlet 12 is provided at one side of the housing 10 and communicates with the outside to provide a passage through which food waste flows from the outside into the inside of the housing 10. The forming position of the inlet port 12 is not particularly limited, and the open top surface of the housing 10 can function as the inlet port 12, as shown in Figs.

The crushing unit 20 may include a rotating shaft 21 rotatably mounted on the housing 10 and a screw extending from the rotating shaft 21 and crushing the food garbage while pushing the food garbage.

The lower end of the rotary shaft 21 is inserted into a shaft hole 14 formed at a lower end of the housing 10 so as to be rotatably supported and includes a bearing 24 for smooth rotation of the rotary shaft 21, An O-ring 25 and the like for preventing leakage to the outside can be mounted (see Fig. 5). A motor (not shown) may be coupled to the lower end of the rotating shaft 21, which is exposed to the outside of the housing 10 through the shaft hole 14, to provide a driving force.

The type of the motor that can be engaged with the rotary shaft 21 is not particularly limited. For example, the rotary shaft 21 may be coupled to a low-speed drivable motor motor. A gearbox 22, which is coupled to the rotary shaft 21, (Not shown) may be installed.

The upper end of the rotary shaft 21 can be rotatably supported by the support lid 30 mounted on the inlet 12 like the lower end of the rotary shaft 21. 3, the support lid 30 may have a rotation support base 32 provided at its center with a shaft groove 32a capable of rotatably supporting the upper end of the rotation shaft 21. [ A bearing 26 for smooth rotation of the rotary shaft 21 may be mounted on the upper end of the rotary shaft 21.

The screw is formed along the outer circumferential surface of the rotary shaft 21 and functions to crush the food waste introduced through the inlet 12 while pushing the food waste.

The spiral wing 22 is formed in a spiral shape along the outer circumferential surface of the rotary shaft 21, and can pressurize and transport the food waste. That is, the spiral blade 22 can pressurize and transfer the food waste toward the axial direction of the rotary shaft 21, that is, toward the lower end from the upper end of the rotary shaft 21. [

The blade 23 extends from the end of the spiral blade 22 so as to face the crush plate 11 and can function to crush food waste. That is, the blade 23 is provided at the end of the spiral blade 22 so as to face the crush plate 11 provided in the housing 10, and can grind the food waste by the interaction with the spiral blade 22. Details of the food pulverizing action between the blade 23 and the crushing plate 11 will be described later.

The discharge port 13 provides a passage through which the food waste disintegrated by the crushing unit 20 is discharged to the outside. The position of the discharge port 13 is not particularly limited and may be formed in the tangential direction of the rotary shaft 21 at the lower portion of the housing 10, for example.

Fig. 4 is a partially enlarged view of the grinding unit of Fig. 1, and Fig. 5 is a cross-sectional view of the housing of Fig.

In order to prevent contamination of environment due to food waste, it is desirable to grind food waste to the best possible level and discharge it. Therefore, the disposer 1 according to a preferred exemplary embodiment of the present invention may have the following structure in order to crush food garbage as finely as possible.

For example, the rotary shaft 21 may have a conical shape in which the diameter? Gradually increases from the front end to the rear end.

As shown in FIG. 4, the rotary shaft 21 has a conical structure in which the diameter gradually increases from the front end to the rear end, that is, from the upper end to the lower end. Therefore, the pressure applied to the food waste by the spiral blade 22 increases from the upper end to the lower end of the rotary shaft 21, so that the food waste can be finely crushed.

For example, the spacing? Between adjacent threads of the helical wings 22 may become gradually narrower from the front end to the rear end.

As shown in Fig. 4, the spiral wing 22 has a structure in which the interval? Between threads gradually decreases from the tip end to the rear end, that is, from the upper end to the lower end. Therefore, the pressure applied to the food waste by the spiral blade 22 increases from the upper end to the lower end of the spiral wing 22, so that the food waste can be finely ground.

For example, the housing 10 may have a crushing plate 11 composed of a plurality of concave-convex grooves 11a and a plurality of concave-convex protrusions 11b alternately formed along the inner surface. The food waste can be moved to the blade 23 by the centrifugal force of the spiral blade 22 and can be crushed by the crushing action between the blade 23 and the crush plate 11. [

5, a plurality of recesses and protrusions 11a and recesses and protrusions 11b are alternately formed on the inner surface of the housing 10, and a plurality of recesses and recesses 11a and recesses and protrusions 11b A crushing plate 11 for crushing food waste can be formed. The recessed groove 11a of the crush plate 11 preferably has a semicircular cross-sectional shape, but is not limited thereto. For example, it may have a triangular or quadrangular cross-sectional shape.

Since the crush plate 11 is provided on the inner side surface of the housing 10 as described above, the crush plate 11 and the blades 23 provided at the ends of the helical blade 22 can be disposed facing each other. The food waste is moved between the blades 23 and the crushing plate 11 by the centrifugal force of the spiral wings 22 while being pressed by the spiral wings 22 to rotate the blades 23 Can be finely ground by the crushing action between the crushing plates (11).

More specifically, the crushing plate 11 may perform a function of crushing food similar to a millstone, and the blade 23 may function to cut food waste to a small size. That is, the disposer 1 is capable of cutting food at the same time as cutting the food through the blade 23 and the crush plate 11.

Therefore, the food waste can be more efficiently crushed than when the food waste is merely cut using only the blade 23. As a result, the food waste can be finely pulverized and discharged to prevent environmental pollution, and the amount of electric power required for pulverizing food waste can be reduced, thereby reducing electricity costs. In addition, noise and vibration generated during grinding of food waste can be reduced compared with a general disposer for grinding food waste using only sharp blades or blades.

The open upper surface of the housing 10 functions as an inlet 12 through which food waste flows. The user's hand is moved through the inlet 12 to the blade 20 of the grinder unit 20 during operation of the disposer 1. [ There is a fear of being injured by contact with the contact portion 23. In order to prevent this, the blade 23 may be extended from a position spaced from the tip of the spiral blade 22 by a predetermined distance.

4, the blade 23 can be extended from the tip of the helical blade 22, that is, a position spaced from the starting point 22a of the helical blade 22 by a predetermined distance. Therefore, even if the user's hand enters the inside of the disposer 1 through the inlet 12, the blade 23 is not formed at the tip of the spiral blade 22, It is possible to prevent the user from being injured.

FIG. 6 is a view for explaining a system for processing food wastes using the disposer of FIG. 1. FIG.

Since the disposer 1 is a device for crushing and discharging food waste finely, the disposer 1 is installed in the sink 40 without separating and collecting the food waste into the special collection box, thereby discharging the finely crushed food waste to the sewer pipe .

More specifically, the inlet 12 and the drain port 42 of the sink 40 are connected through a connection pipe 50, and the drain port 13 and the decomposition tank 60 are connected to the drain port 42 ) Can be crushed, decomposed, and discharged.

The connection pipe 50 connects the disposer 1 and the drain port 42 of the sink 40 to supply water and food waste discharged through the drain port 42 of the sink 40 to the disposer 1 It is absent.

The connector 50 can also allow the disposer 1 to be spaced apart from the drain 42 of the sink 40 by a predetermined length so that the user's hand can not touch the disposer 1. [ Particularly, at least one bent bent portion is provided on the path of the connection pipe 50 so that the user's hand contacts the disposer 1 through the drain port 42 of the sink 40 and the connection pipe 50 more effectively .

Both ends of the connection pipe 50 are detachably coupled to the drain port 42 of the sink 40 and the inlet 12 of the disposer 1 to facilitate repair and inspection of the connection pipe 50 And the connecting pipe 50 can be freely exchanged in accordance with the size of the sink 40, which is convenient.

The decomposition tank 60 is connected to the discharge port 13 of the disposer 1 to receive the pulverized food in the disposer 1 and the pulverized microorganisms are cultivated in the food waste through the microorganism supply unit 52, And discharges the disassembled food waste to the sewer. Thus, by disposing the decomposing tank 60 between the disposer 1 and the sewer so as to disassemble and discharge the food garbage, it is possible to prevent the river or the like into which sewage and sewage are introduced from being contaminated by the food garbage.

Hereinafter, a process of grinding, disassembling and discharging foodstuffs by the food waste disposal system 2 implemented using the disposer 1 according to a preferred exemplary embodiment of the present invention will be described.

First, when water and food waste are discharged through the drain port 42 of the sink 40, the discharged water and the food waste pass through the connection pipe 50 and through the inlet 12 of the disposer 1 to the disposer 1). If the metal is introduced into the inside of the disposer 1 together with water and food waste, the metal is sensed by the metal detection sensor installed at the inlet 12 of the disposer 1, Stopped.

Next, the food waste introduced into the inside of the disposer 1 through the inlet 12 is crushed while pressurized and conveyed by the crushing unit 20 provided in the disposer 1.

The diameter α of the rotary shaft 21 increases from the upper end to the lower end and the spacing β between the threads becomes narrower from the upper end to the lower end of the helical wings 22. Therefore, the helical wings 22, It is possible to carry out the transfer while pressurizing. Since the crush plate 11 is provided on the inner surface of the housing 10 of the disposer 1 and the blade 23 is provided at the end of the helical blade 22, The food waste to be pressurized and transported can be crushed finely by the crushing action of each other.

Thereafter, the food waste discharged to the outside of the disposer 1 through the discharge port 13 of the disposer 1 is decomposed by the microorganisms inside the decomposition tank 60 and then discharged through the discharge port 64 to the drain Can be discharged.

The water discharged through the discharge port 13 of the disposer 1 and the pulverized food waste flow into the decomposition tank 60. The food waste is discharged into the decomposition tank 60 for a predetermined time And is decomposed by the microorganisms supplied from the microbial supply part 52 while staying. The food waste decomposed in the decomposition tank 60 is discharged to the sewer through the discharge port 64 of the decomposition tank 60 and the food waste discharged to the sewer is continuously decomposed during the flow of the sewer. Therefore, it is possible to prevent contamination of sewage, river, and the like by the food waste discharged to the sewer.
