Abstract
A drain system directly injects fluid into a drain or drain adapter. The drain or drain adapter includes at least one vortex blocking flow disrupter disposed on an internal surface of the drain or drain adapter. The flow disrupter comprises at least one surface discontinuity configured to lessen the strength of a vortex from the injected fluid to prevent the fluid from rising into the sink basin.
Claims20
A vortex blocking drain adapter comprising:
- a sidewall extending from a first end to a second end, wherein an interior of the sidewall comprises structure defining a plurality of protrusions extending radially inwardly, and wherein the first end of the sidewall is configured to be coupled to a drain of a sink basin, and a second end is configured to be coupled to a drainpipe or garbage disposal.
A drain system comprising:
- a drain assembly extending from a bottom wall of a sink basin;
- and
- a drain adapter operably coupled to the drain, the drain adapter having a sidewall including an interior surface comprising structure defining a plurality of protrusions extending radially inwardly, the drain adapter being configured to reduce or prevent formation of a vortex in the drain assembly.
A drain adapter comprising:
- a sidewall removably coupleable to a drain assembly of a sink basin at a first end of the sidewall, and removably couplable to a drainpipe or a garbage disposal at a second end of the sidewall, wherein the drain adapter is configured to block formation of a vortex in the drain assembly to prevent fluid backflow into the sink basin.
