  • Housing with integral drain for removing condensate from a heating and air conditioning unit
    Patent number: 5894737
    Abstract: An improved housing for draining condensed water from the interior of a heating and air conditioning unit installed in a motor vehicle. The contoured bottom wall of the housing includes a raised portion surrounded by a series of sloped channels which lead to a collection basin having a drain. A fan or blower forces air through the housing inlet and past the heating and cooling elements. A portion of one of the sidewalls adjacent the air inlet interrupts the entering air to create a low pressure area. Condensed moisture is drawn along the sloped channels towards a collection basin located in the low pressure area. A drain is provided in the collection basin to remove the moisture from the housing.
