Abstract:
The present invention relates to a drain device for draining wastewater, urine, etc. through a drainpipe and blocking bad odors emanating from the drainpipe, and more particularly, to a drain device comprising: an outer container coupled to a top of the drainpipe; a cover seated on a top of the outer container; a conical sloped plate coupled at a lower center of the cover; and a blocking layer formed in a trapezoidal cylindrical shape and coupled between the cover and the sloped plate, the blocking layer having a narrow upper inlet, a wide lower outlet, and a bent portion formed below the upper inlet. Accordingly, water is not left remaining, foreign objects are prevented from being entrapped and are discharged more easily, and the drain device can be reliably used for a long period of time without deforming.
