Abstract
Disclosed herein is a structural drain trap for preventing spread of pathogens between floors, which has an improved structure in which it includes a cover and an outer chamber that are easily coupled to and decoupled from each other and provides a drain line configured to have a double structure at inner and outer portions thereof. Therefore, it is possible to prevent pathogens such as Coronavirus as well as odors or pests from flowing backward as much as possible, and thus to prevent pathogens from spreading through the gap between the floors of buildings such as apartments.

A structural drain trap for preventing spread of pathogens between floors, comprising:
- a cover (10) comprising a hollow cylindrical top body (11) connected to a drain pipe (2) of a drain hole (1), and a hollow hemispherical bottom body (12) extending downward around a lower end of the top body (11);
- a cylindrical outer chamber (20) disposed beneath the bottom body (12) of the cover (10), and having an internal space (21) that is open upward;
- a hollow cylindrical inner chamber (30) disposed to pass through a bottom center area of the space (21) of the outer chamber (20), the inner chamber (30) having an upper inlet, which is disposed in the space (21) and is spaced along an inner wall of the space (21) to define a first annular interspace (S1), and a lower outlet exposed to the outside;
- a cylindrical middle chamber (40) having a lower end, which is disposed around the first interspace (S1) to partition an upper-side first interspace (S1) when the first interspace (S1) is divided into upper and lower halves, and an upper end, which is disposed in an upper center area of the space (21) of the outer chamber (20) by two or more middle relay rods (41) connected to an upper end of the outer chamber (20), the middle chamber (40) having an inner accommodation part (42) that is open downward;
- a holding means (70) for allowing the cover (10) and the outer chamber (20) to be coupled to and decoupled from each other;
- and
- an annular watertight member (80) disposed on a contact surface between the bottom body (12) of the cover (10) and the outer chamber (20).
A structural drain trap for preventing spread of pathogens between floors, comprising:
- a cover (10′) seated on a drain hole (1) and having a drain pipe fitting groove (13) formed on a lower end thereof so that a drain pipe (2) is fitted into the drain pipe fitting groove (13), an outer chamber (20′) seated on the cover (10′), and an inner chamber (30′) seated on the outer chamber (20′), wherein:
- the outer chamber (20′) and the inner chamber (30′) are in the form of an open top and cylindrical container;
- the outer chamber (20′) has a larger diameter than the inner chamber (30′);
- the outer chamber (20′) has a body length (L1) greater than a body length (L2) of the inner chamber (30′);
- the outer chamber (20′) has a plurality of permeable holes (24) arranged circumferentially on its upper side;
- wastewater introduced into the center of the inner chamber (30′) is discharged to the drain pipe (2) through the permeable holes (24);
- and
- water is filled from the bottom of the outer chamber (20′) to the permeable holes (24), thereby preventing various viruses and bacteria, including odors, from communicating vertically.
