Description

  The present invention relates to a drain pan for preventing slime generation in a bathroom ventilation air conditioner.

When the bathroom ventilation air conditioner is cooled or dehumidified, the air guided to the bathroom ventilation air conditioner is cooled by the heat exchanger, and moisture in the air is condensed and collected in the drain pan as drain water. This drain water is sucked up by the drain pump from the drain pan, and discharged to the outside of the bathroom ventilation air conditioner by the drain hose. It gradually changed, and the drain pump and drain hose were clogged.
