The tray has a receiver portion (100), and a tap structure (130) that forms a space where water flowing from the receiver part is captured. The tap structure forms a discharge wastewater pipe (150). A protruding element or cylindrical covering part (142) when applied to the wastewater pipe protrudes inside the tap structure such that the protruding element is immersed in water and is trapped without engaging a surface of the tap structure. |
