The present invention relates to a sieve for drainage, and in particular, to a sieve for sink drains capable of reducing the capacity of food waste by easily dehydrating moisture contained in food waste.

In general, a sink for washing dishes or fruits or vegetables is installed in a kitchen such as a home or a restaurant. A drain hole is formed in the sink to allow water used for washing dishes, fruits, vegetables, etc. to be discharged to the sewer.

A strainer is installed at the drain of the sink to prevent food waste from being discharged to the sewer with water. The top of the strainer is opened so that water and food waste can be put into it, the side and the bottom are blocked to filter food waste, and a number of holes for drainage are formed on the side and bottom.

On the other hand, the sieve installed in the drain of the sink should be discarded from time to time in order to prevent the generation of odors or the growth of bacteria caused by the decay of the food wastes filtered therein.

However, since the conventional sieve is installed in the drain in a state formed in a simple tubular shape, in order to discard the food waste inside the sieve, there is an inconvenience of having to pull out the sieve from the drain and turn it over and shake it off in a separate food waste bin or bag. .

In addition, the food waste filtered through the sieve contains a considerable amount of moisture, and thus, there is a problem that the food waste is easily decayed or the leachate is leaked.

However, conventionally, a method of allowing moisture to be naturally removed from the food waste by leaving the strainer in which food waste is collected for a long time has been used, and thus there is a problem such as occurrence of odor or the growth of bacteria due to decay or the like during the leaving time of the sieve.

An object of the present invention is to solve the above-described problem, and to provide a strainer for a sink drain that is installed at a drain of a sink to easily dehydrate moisture contained in food waste to reduce the capacity of the waste.

A strainer for drainage according to an embodiment of the present invention includes a strainer having a multi-stage sidewall and a lower plate connected to the lowermost end of the sidewall by being inserted into the drainage hole of the sink and into the food waste through the upper opening; A cover portion consisting of a lid coupled to the top of the manure portion and a handle connected to the lid; And an elevating part provided on each of the manure part and the cover part to connect the cover part and the manure part.

Here, the lifting part is characterized in that the inner volume of the manure part is changed by raising or lowering the lower plate according to the vertical movement of the handle.

The strainer for drainage according to the present invention can easily dehydrate moisture contained in the food waste by compressing the food waste inside the sieve by changing the volume of the sieve according to the operation of the cover portion coupled to the sieve through which food waste is filtered. I can.

Accordingly, the sieve of the present invention can easily dehydrate moisture from food wastes filtered through the sieve, even if a separate moisture dewatering device is not provided, thereby improving convenience and efficiency of moisture removal.

In addition, the sieve for drainage according to the present invention can easily discharge the food waste from which moisture has been removed by controlling the opening and closing of the lower plate of the sieve according to the manipulation of the handle of the cover portion coupled to the sieve.

Accordingly, the present invention can increase the convenience and efficiency of discharging food waste compared to a conventional discharging method of shaking off food waste in a state in which the strainer is turned over.
