Description

{Filters for drainage}

The present invention relates to a drainage screening apparatus for preventing foreign matter such as food waste contained in wastewater discharged from a sink by being connected to a drainage port and preventing the foreign matter from flowing into a drainage pipe so as to maintain the stability of the drainage apparatuses. Can be applied irrespective of the depth of the drain pipe constituting the drain hole, thereby increasing the efficiency of use, and more particularly, to a drain hole manure apparatus which can easily remove the food waste residue subjected to the manure treatment and is convenient to use.

Generally, a sink is a kitchen equipment installed in a kitchen such as a home or a restaurant for washing kitchen utensils such as various dishes. The kitchen sink is supplied with washing water, and the washing water used is discharged to the outside .

The drain port is connected to the bottom surface of the washing tank for washing the kitchen container so that the washing liquid stored in the washing tank can be easily drained to the outside. The drain port prevents waste such as food waste from flowing into the drain pipe The feeder is removably mounted

The general structure of the drain hole provided in the sink includes a drain hole formed at the center of the bottom surface of the sink in a downward direction and a filter net to filter food waste is inserted and fixed in the drain hole, A drain hose is connected to discharge the washing water, and a filtering net cover is installed on the upper side of the filtering net.

Therefore, when the washing water and the food waste are introduced through the drain hole, the food waste is filtered by the drain hole and only the washing water is discharged through the drain hose.

In the above, the filtering net serves to filter out the dirt such as food and the like through the drain port, and is mainly made of plastic or stainless steel.

On the other hand, the conventional screening filter as described above is always wet and filled with dirt such as food, so that not only bacteria grow but also bad odor caused by bacteria.

Accordingly, in order to prevent the propagation of germs in the sieve, the food waste must be collected and disposed of every time the food waste is filled in the sieve.
