The present invention according to this embodiment is generally similar to one embodiment, except that in one embodiment, the compression screw 47 is provided with a screw blade 46 over the entire length of the rotating shaft 48, but this embodiment In the helical grinding portion 63 is formed in the front portion of the compression screw 47 having a screw blade 46, chamfering one side of the helical grinding portion 63 between the inner surface of the casing (31) Since only the chamfered portion 64 which forms the space portion is different, the description of the remaining structures identical to each other will be omitted.

Further, in the present invention, another embodiment can be realized with a simpler structure than the above one and this embodiment, and this another embodiment forms an inlet and a drain at the bottom of a known drain trap formed directly below the outlet. A pair of compression screws which rotate in the opposite direction by a reduction motor are installed in a casing having an external heater installed at the rear end, with screw blades engaged with each other, and a rear outlet of the casing has a discharge port at the center thereof. The discharge pipe is installed, and the center of the discharge port is pointed forward, and the inner heater whose outer diameter is reduced toward the rear, it can be installed to be installed in the horizontal direction by the radially formed arm.

Reference numeral "4" in the drawings denotes a packing, and "6" denotes a backflow prevention film.

Referring to Figures 1 to 10 the operational relationship of the present invention configured as described above are as follows.

First, an embodiment of the present invention shown in FIGS. 1 to 8 will be described.

In the case of treating food waste according to the present invention, after the internal and external heaters 43 and 44 are heated by turning on a switch for supplying power to the internal and external heaters 43 and 44, The food waste is thrown into the dishwasher 2 while the deceleration motor 51 is operated by turning on a switch for driving the reduction motor 51.

The food waste dumped into the dishwashing container 2 goes down to the inside of the drain trap 10. The outlet 16 of the drain trap 10 is installed in the lower outer side of the drain trap 10 so that the outlet is directly below. It is discharged slowly to the discharge port 16, but the bottom is formed to be inclined toward the discharge port 16 side of the food waste coming down to the inside of the drain trap 10 through the discharge port 16 without casing of the dehydration dryer (30) 31 flows into the interior.

If the food waste does not go down well to the outlet 16, the food waste is easily pushed down to the outlet 16 by slightly turning the tap water and pushing it with a long stick such as a rod.

At this time, when the bottom of the drain trap 10 is blocked, when a long and hard object such as chopsticks or spoon is introduced into the drain trap 10, the bottom of the drain trap 10 is blocked, and the outlet on the side As long as the (16) is formed, there is no fear that the elongated foreign matter will flow into the casing 31,

However, when a small and hard foreign matter is introduced into the casing 31 through the discharge port 16, the foreign matter is caught in the compression screw 47 to interfere with the rotation of the compression screw 47, so that the reduction of the reduction motor 51 When the rotation becomes slow, the overload circuit breaker 53 installed in the reduction motor 51 detects this and stops the rotation of the reduction motor 51. After the motor stops, the foreign matter installed as a screw under the casing 31 is stopped. Opening the removal cover 36 can easily take out the foreign matter caught in the inside, after removing the foreign matter reassemble the foreign material removing cover 36 and proceeds to the food waste again.

When the food waste is introduced into the casing 31 as described above, the food waste is interposed between the pair of compression screws 47 installed so that the upper portion rotates inward in the engaged state. Food waste is bitten in between 47).

When food waste is introduced into the grooves of the bone shape formed between the pair of compression screws 47 as described above, the outer periphery of the screw blade 46 of the compression screw 47, which rotates inward, respectively, is crushed. The protrusion 46a is formed to protrude so that the food waste placed between the two compression screws is rotated while being hooked, and bites back between the two compression screws.

When food waste is pulled into and pulled between two compression screws that are engaged with each other, the two compression screws are caught between the screw blades 46 spirally formed on the outer circumference thereof. The food waste entering into the state is primarily pulverized, and after the food waste is separated between the two compression screws 47, the crushing protrusion 37 and the respective screw blades formed to protrude on the inner wall of the casing 31. By the grinding projections 46a formed to protrude on the outer circumference of the 46, the grinding is again performed secondarily.

As food waste is crushed between the two compression screws as described above, the space between each pitch of the screw blades and one pitch becomes narrower toward the rear, so that the food waste is crushed and dehydrated and the food waste continues to the rear side. The water generated when dewatered as described above is drained to the primary drain 35 formed in the foreign matter removing cover 36.

As described above, a large amount of water is removed as the first dewatered water is drained from the primary drain 35 on the front side. In this state, the food waste that is pushed to the rear side is crushed and compressed by the compression screws engaged with each other. The water thus dehydrated and thus dehydrated is drained to the drain 38 on the rear side of the casing 31.

As described above, the food waste drained through the first and second stages is in a state in which a large amount of water is dehydrated, and the dehydrated food waste is transported to the rear outlet 40 by the compression screw 47 that rotates continuously. As the inside and outside heaters 43 and 44 are heated in and out of the outlet 40, the outlet 40 in which the inside and outside heaters 43 and 44 are installed is hotly heated, and thus the dehydrated body 40 passes through the outlet 40. Food waste will be dried by its heat.

At this time, the outlet 40 is formed in the shape of a cylindrical pipe or an elliptical pipe, the shape of the food waste discharged through the outlet is also circular, or elliptical discharge, so if the heater is installed only outside the circular Or the food waste discharged in the oval will be dried only the outside of the waste and the interior will not be dried, in the present invention is discharged through the discharge port according to the inner and outer heaters 43 and 44 are installed together inside and outside the discharge port 40 The inside and outside of the food waste will be dried together.

And, when the food waste is discharged through the discharged heat generated by the high temperature, when the food waste is compressed and dehydrated in the previous step, when passing between the outer circumferential surface of the inner heater 43 and the inner circumferential surface of the outlet 40. In the present invention, the tip of the outer diameter of the inner heater 43 is sharply formed in a conical shape so that the food wastes transported in a cylindrical shape or an elliptical shape are scattered to the outside. Food waste is passed between the inner circumference of the discharge port 40 and the outer circumference of the inner heater 43, the outer diameter of the inner heater 43 becomes smaller toward the rear, so that it is easily escaped to the outside without great resistance. ,

In addition, when the food waste is discharged to the outside through the outlet, the outlet is heated by a high temperature by the inner and outer heaters and the food waste contains a small amount of water, so that the food is dried under heat In the garbage, gas including water vapor is generated. In the present invention, as shown in FIG. 8, exhaust grooves 40a and 43a are formed on the inner circumferential surface of the outlet and the inner circumferential surface of the inner heater, respectively, so that the gas including the steam is formed. Discharge into the exhaust grooves (40a, 43a) is a food waste is more easily discharged and can minimize the discharge noise.

Food wastes discharged to the discharge port 40 as described above is introduced into the waste container 60 connected to the discharge port 40, the waste food container 60 containing the dried food waste is a synthetic resin containing nano silver Because it is manufactured or manufactured by coating a material containing a silver (synthetic resin) on a metal plate, sterilization and deodorization is performed by the antimicrobial properties and excellent deodorizing action of the nano silver.

If the outlet 16 is clogged, or if the food waste introduced into the drain trap 10 flows down to the outlet 16 with the force of water, the amount of water is too high. If the water does not escape to the outlet 16, the water may flow back to the overflow, but on one side of the drain trap 10 as shown in Figure 2 overflow drain drain 13 in preparation for overflowing tap water And the overflow pipe portion 15 is formed, when water flows back up the drain trap 10, the water flows into the overflow drain 13 formed in the upper portion of the drain trap 10 It flows to the overflow pipe portion 15 provided on one outer surface of the drain trap 10 and is drained to the drain hole 14 below.

Therefore, even if the tap water flows excessively, there is no fear that the water will overflow and overflow.

The following is a description of this embodiment of the present invention shown in Figs. 9 and 10, which is a helical grinding part 63 and this helical at the front of the compression screw 47 when compared with the embodiment. Since only one chamfer 64 is formed on one side of the pulverization part, it is different from the exemplary embodiment, and only the changed structure will be described.

That is, when food waste is put into the upper part between the two helical grinding parts 63, the two helical grinding parts 63 rotate to face inward when viewed from the top, respectively, so that the upper part of the two helical grinding parts 63 is turned on. The food waste introduced into the two helical grinding units 63 are crushed and crushed, and the food waste that is crushed out of the two helical grinding units 63 is crushed by a grinding protrusion 37 formed on the inner circumferential surface of the casing 31. Secondary grinding is achieved.

When food waste comes in between the two helical grinding parts 63 as described above, the food waste is compressed between the two helical grinding parts 63 and is formed by a gear part spirally formed in the helical grinding part 63. Grinding and dehydration take place and are transported to the rear side.

The crushed and dehydrated by the helical grinding unit 63 formed in such a spiral, and the dehydrated water during transportation is first drained from the primary drain 35, and the helical grinding unit crushed and dehydrated in the helical grinding unit 63 ( In the compression screw 47 installed at the rear of the 63), crushing and dehydration are performed again, and the dewatered water is drained to the outside through the drain hole 38.

The chamfer 64 is formed at one side of the helical grinding part 63, when the chamfer 64 comes upward in the casing 31 between the chamfer 64 and the inner wall surface of the casing 31. A relatively large space is formed so that the bulky food waste such as kakdugi can be easily introduced into the bulky food waste by the enlarged space, and as long as the bulky food waste such as kakduk enters the space, Rotating helical crushing unit 63 can easily crush and dehydrate bulky food waste such as diced.

As described above, the food waste treatment apparatus for a sink according to the present invention has a pair of compression screws installed inside the casing so as to rotate in opposite directions, and protrudes the grinding protrusions at regular intervals on the outer circumference of the screw blade. The food waste introduced into the inside can be dried well between the two compression screws, and the food waste is further crushed by the grinding protrusion, and an internal heater is added to the center of the discharge port where dried waste is discharged. By installing it as a very useful effect to be able to dry well to the center of the food waste discharged to the outlet.

In addition, in another embodiment of the present invention by forming a helical grinding portion of the helical gear type in front of the compression screw to form a chamfer cut one side of the helical grinding portion, the food waste flowing into the casing both helical grinding portion and chamfering portion By the more drift between the helical crushing parts on both sides is effective to improve the grinding efficiency.
