Abstract
An appliance includes a housing defining a cavity having an opening, and a cover member pivotable between open and closed positions with respect to the opening to selectively allow access to the cavity through the opening. A plurality of vents is engaged with the housing about the opening, including a positive pressure vent configured to direct a positive airflow in a first lateral cross-opening direction, a negative pressure vent configured to apply a suction in a second lateral cross-opening direction to pull at least a portion of the positive airflow therethrough, and opposing first and second neutral vents arranged laterally across the opening and configured to neutralize effects on and maintain the positive airflow from the positive pressure vent and pulled through the negative pressure vent by the applied suction caused by the cover member pivoting between open and closed positions. An associated apparatus and method are also provided.
