Waterless urinal, has chamber extended from siphon along direction of gravitational force, where chamber from height of wall-side connector and arrangement of sealing fluid has certain length before entering into another chamber

摘要

The urinal (1) has a catchment basin (2) and a siphon (3) fluidically connected with a wall-side connector (7) and a sewage system (8). The siphon comprises a chamber system (K) with a chamber (K1). The siphon is utilized as a stench trap for receiving sealing fluid (S), and comprises a discharge element (9) with an observable aperture (10) on a side of the catchment basin. The chamber is extended from the siphon along direction of gravitational force. Length of the chamber from height of the connector and arrangement of the fluid is about 10 cm before entering into another chamber (K2). The sealing fluid comprises biological degradable substance. The urinal is made of plastic, stainless steel, steel alloy or ceramic material.
