The first impeller 150 is provided adjacent to the bottom plate 102 to mix the food waste separated on the bottom plate, and the first impeller 150 is disposed adjacent to the bottom plate 102. In this case, To the transfer unit 200 side.

In this embodiment, the cutter 130 is further provided with a passage plate 140 having a plurality of through-holes formed therethrough, so that only the crushed material having a predetermined particle size or less can be passed therethrough.

The drainage hole 104 is formed in the bottom plate 102 and the drainage pipe 630 is provided in the bottom of the bottom plate 102 to allow the water flowing into the crushing unit 100 to flow to the sewage facility.

The feeding unit 200 communicates with the crushing space and feeds the food waste pulverized by the cutter 130 to the drying unit 300 side. In the present embodiment, the food waste is transported from the lower side to the drying unit 300 side by the rotation of the transport shaft 210 and the blade 220 formed around the transport shaft 210.

The drying unit 300 has a drying space 301 communicated with the conveyance unit 200 and the food waste is conveyed from the conveyance unit 200 as described above. The drying unit 300 includes a second rotating unit 310 extending vertically from the center of the bottom plate 302 and rotatably installed to introduce outside air into the crushing space, And a second impeller 250 provided around the second impeller 250 to mix food waste.

The first rotary unit 110, the feed shaft 210 and the second rotary unit 310 are formed so as to be simultaneously rotated by the gear 510 driven by the rotation of the drive motor 500. In this case, Of course, it is needless to say that the first rotating unit 110, the feeding shaft 210 and the second rotating unit 310 may be separately rotated.

In this embodiment, the heating unit 370 is installed at a lower portion of the drying unit bottom plate 302, And the drying space 301 may be heated to dry the food waste. In addition, the heating unit 370 can heat the outside air flowing into the second rotating unit 310 together, and the heated outside air is discharged through the outlet mechanism 322. Although not shown in the drawing, the outlet 322 may be provided with a pressure valve (not shown) so that the air may be opened to allow air to flow if the pressure inside the drying space 301 is lower than the set value.

Since the outlet mechanism 322 is installed on the second rotary unit 310, the dried and heated air can be sprayed from the inside of the food waste accumulated in the drying space 301 to improve the drying efficiency.

Alternatively, when the flow path of the outside air is formed from the upper direction to the lower direction, the effect of the outside air injection may be greatly reduced because the outside air collides with the rising up air heated by the heating.

4 is a rear view of an exhaust unit of the garbage disposal apparatus according to the first embodiment of the present invention.

4, the exhaust unit includes an exhaust pipe 640 connected to the exhaust port 360 and configured to cause the air in the drying unit to flow to the sewage system, And a nozzle 632.

The exhaust unit further includes a drain pipe (630) provided at a lower portion of the bottom plate of the crushing unit to flow the water flowing into the crushing unit to the sewage system. The exhaust pipe (640) And the drain pipes 630 are connected to each other. Thus, the air that has flowed from the drying section can be flowed to the sewage system through the exhaust pipe 640 and the drain pipe 630.

FIG. 5 is a cross-sectional view showing the inside of an exhaust part of a garbage disposal apparatus according to a first embodiment of the present invention.

As described above, the discharge pipe 630 is provided with a spray nozzle 632, and the spray nozzle 632 injects water into the air flowed by the exhaust pipe 640.

The reason why the water is injected into the exhausted air is that when the U-shaped pipe 620 is provided on the flow path to the sewage system when air is discharged through the water pipe, the air can not flow to the sewage Because it can backflow.

That is, water is sprayed to continuously flow the water in the U-shaped pipe 620 so that the U-shaped pipe 620 is always opened, so that the exhaust of the dry air containing odor can be facilitated.

In addition, the dry air flowing into the exhaust pipe 640 has a malodor of food waste. At this time, since the dry air is in a heated state, the odor is also activated. Accordingly, by spraying water into the dry air containing the odor, the temperature is cooled to lower the activity of the odor, and the odor component contained in the air can be dissolved in the water and easily flowed to the sewage system.

Meanwhile, in this embodiment, the injection nozzle 632 can receive water from the water supply pipe 610 through the transportation pipe 650 and discharge the water. The transport pipe 650 may be a pipe for supplying tap water to a sink or a faucet. In this embodiment, the injection nozzle 632 is provided on the drain pipe 630 side, but it may be provided on the exhaust pipe 640 side.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
