Title:
APPARATUS FOR PREVENTING OFFENSIVE ODORS FOR A DRAIN
Document Type and Number:
WIPO Patent Application WO/2010/140761
Kind Code:
A2
Abstract:
The present invention relates to an apparatus for preventing offensive odors for a drain. The apparatus for preventing offensive odors for a drain according to the present invention comprises a mounting member, a main body member, and a linear and inclined resilient band. The mounting member includes a ring-shaped support plate portion mounted on the drain, a hollow tube-shaped neck portion which extends downward from the support plate portion and the center of which has a drainage path, and a curved portion for interconnecting the support plate portion and the neck portion. The main body member includes a tubular mounting portion coupled to the outer surface of the neck portion through a connecting element, and a discharge portion extending from the lower portion of the mounting portion so as to be selectively opened. The linear and inclined resilient band is arranged at the outer surface of one side of the discharge portion in the widthwise direction such that both ends of the band are located at different heights. The thus-configured apparatus of the present invention is advantageous in that the water inlet part of the mounting member has a slow curve to enable the smooth inflow of wastewater, and the resilient band arranged at the outer surface of the discharge portion of the main body member is inclined at a predetermined angle to enable the discharge portion to be opened in an elliptical shape, which enables the discharge portion to be easily opened even when the amount of wastewater is small, thereby improving drainage efficiency and reducing the fatigue of the resilient band, thus improving durability and ensuring a long lifespan.
