Abstract

Verfahren zum Entleeren eines Wasserkastens (11) mit einliegendem Doppelheberrohr für die Toilettenspülung, wobei der Wasserkasten (11) Mittel zum Befüllen hat und eine erste Heberrohreinheit mit einer zum Inneren des Wasserkastens offenen Eintrittsöffnung und eine zweite Heberrohreinheit mit einer mit einem Ablaufstutzen verbundenen Auslaßöffnung hat und wobei eine Entleerung des Wasserkastens durch zeitlich begrenztes Entlüften der ersten Heberrohreinheit eingeleitet wird, wobei die aus dem Wasserkasten abfließende Wassermenge durch Steuerung von Luftvolumenströmen zwischen Gesamtentleerung und Teilentleerung steuerbar ist.
Dabei wird zur Gesamtentleerung des Wasserkastens (11) die erste Heberrohreinheit nur kurz belüftet, während zur Teilentleerung die erste Heberrohreinheit während des kompletten Spülvorgangs belüftet wird.

Figure imgaf001
A method for emptying a water box (11) with inlaid double jack tube for toilet flushing, wherein the water box (11) has means for filling and has a first siphon tube unit with an open to the interior of the water box inlet opening and a second siphon tube unit with an outlet connected to an outlet opening, and wherein an emptying of the water box is initiated by temporary venting of the first siphon tube unit, wherein the effluent from the water box volume of water is controlled by controlling air flow rates between total emptying and partial emptying.
In this case, for the total emptying of the water tank (11), the first siphon tube unit is only briefly vented, while for partial emptying the first siphon tube unit is vented during the entire flushing process.
