Patent ID: 8287630

Claim:
A grease water separation apparatus for an indoor grill comprising: an air chamber being in communication with the indoor grill; a water scattering member comprising an internal space in communication with the air chamber, at least one sprinkling duct, and a pump in communication with the at least one sprinkling duct; a heat exchanger connected to the water scattering member and being in communication with the space of the water scattering member, the heat exchanger comprising a grease filter including a plurality of filter elements and a plurality of grease holes; a liquid collector connected to the heat exchanger and comprising a water reservoir in communication with the pump, a grease reservoir for collecting grease from the grease holes, and a grease water mixing reservoir; a water-grease separator connected to the heat exchanger and being in communication therewith, the water-grease separator comprising a hollow cylinder having one end formed as an air outlet and an inlet at the other end within the water-grease separator, and a bottom water-grease outlet for flowing water and grease to the grease water mixing reservoir; a motor driven centrifugal fan being in communication with the air outlet; and an air filter being in communication with the centrifugal fan and comprising a filter unit, wherein in an operation rising gases from the indoor grill is directed into the space of the water scattering member via the air chamber, water in the water reservoir is drawn to the at least one sprinkling duct by the pump and impinged into the space of the water scattering member in form of vapor by the at least one sprinkling duct, the vapor is mixed with the gases prior to entering the heat exchanger, grease of the mixture is substantially removed by the filter elements and flows into the grease reservoir via the grease holes, vapor of the mixture is directed to the water-grease separator to circulate around the cylinder so that a centrifugal force is generated to separate water and remaining grease from the vapor of mixture, the separated water and grease are impinged on an inner wall of the water-grease separator prior to flowing to the grease water mixing reservoir via the grease water mixing reservoir, air in the cylinder is sucked into the air filter by the centrifugal fan, and the air is filtered by the air filter prior to exiting.
