防止するよう改良された排水トラップに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain trap, and more particularly to an S trap. More specifically, the present invention relates to a drain trap improved to prevent generation of abnormal noise when draining.

An upper portion has a second descending portion connected to the rising portion, and the sealed water is accumulated from the first descending portion to the rising portion.

出も無くなり、異音も防止される。By the way, when water flows into the S trap, the water flowing around the rising end of the rising part flows down the second falling part. When the water flowing down the second descending portion closes the second descending portion like a piston or a plug and flows down, a negative pressure is generated on the upper side of the falling flow, and the water is also sucked into the second descending portion. Then, air is entrained from the first descending section to the ascending section. With the entrainment of the air, an abnormal sound such as “sludge” or “gobogobo” is generated. To prevent this abnormal sound, Japanese Patent Laid-Open No. 1-174730, the second falling section 2 is eccentric to the raised portion 1 as the 4,5 diagram ascender 1 from the second descending portion 2 There is described a drain trap configured so that water flowing into the inside of the second descending portion 2 turns along the inner peripheral surface. When water falls while turning along the inner surface of the second descending portion 2, the axial center portion of the second descending portion 2 becomes hollow, and an air column connected from bottom to top of the second descending portion 2 is formed. Thus, the generation of the negative pressure due to the falling water in the second descending portion 2 is eliminated. In addition, the suction and discharge of the sealing water is eliminated, and abnormal noise is also prevented.

する。In the conventional drain trap shown in FIGS. 4 and 5 , when the flow rate of waste water exceeds a predetermined amount, a large amount of water flows from the rising part 1 to the second falling part 2, and The falling flow of the second descending portion has a piston shape or a plug shape. As a result, the water sealing and the air bubbles are sucked out, and abnormal noise is generated.

Bounced back to the center of the part. As a result, a cavity is formed below the convex portion in the second descending portion. As a result, a piston-like or plug-like downward rainfall flow does not occur in the second descending portion, and the sealed water in the rising portion is not sucked out to the second descending portion. Further, no abnormal noise is generated due to the sealing water suction .

の吸い出しに伴う異音発生も無い。When the drain water flows into the drain trap constructed as described above, the water in the rising part 11 flows out into the second descending part 12 and hits the convex part 13 as shown by an arrow w in FIG. It is rebounded toward the axis of the second descending portion 12. As a result, a cavity is formed below the projection 13. And the second
The falling water flow in the descending part 12 does not become piston-like or plug-like, and no negative pressure is generated in the second descending part 12. For this reason, the water sealed in the water sealing section from the first descending section 10 to the rising section 11 is not sucked out by the second descending section, and there is no generation of abnormal noise due to this sucking.
