TH12926B - The bends of a vacuum-based toilet bowl - Google Patents

Abstract

A vacuum-operated toilet bowl where vacuum is applied between the top and bottom arcs (40, 44 in Fig. 2) of the toilet bowl outlet during flushing, the lower arch is assembled. Provides more reliable assurance that the air channel (64) above the puddle (52) of the lower arc will close rapidly near the start of the flush and will remain open in the During flushing The arched bottom has a bottom wall (50) with a puddle (52) with a basin top (62) of a predetermined height (A) during flushing. And has a wall on top (60) spaced over the top of the basins for the formation The figure is an air channel The upper wall forms a narrow high (100, Fig. 4) vent, which ensures that the air vents are always open during flushing and high vents. The narrow will be quickly shut down by the rapidly flowing water at the beginning of the flush.
