Abstract
A waterless urinal (1) is provided with a pot (17) in which urine (35) accumulates. A float (33) floats on the urine (35) and is pressed upwardly by the buoyancy thereof against an opening (31) in the cover (29) of the pot (17). As soon as a pre-determinable column of urine rises above the float (33), the float (33) is pressed downwardly, and the urine (35) can flow out. In a preferred embodiment, the float (33) can be pulled downwardly by an electromagnet, in order to sporadically empty the urine (35), which has accumulated above the float (33) and the cover (29).
