The invention discloses a discharge method of condensed water in the bottom of a fan volute casing. A trap is arranged on the bottom of the fan volute casing and used as a water seal; pressure from the height of the water seal is higher than wind pressure, so that the condensed water in the volute casing can discharge water automatically through the water seal, without gas mixing, and then the condensed water is refluxed and discharged along the inner wall of an aspiration duct. The discharge method has the advantages of reliable safety of the fan, reasonable, timely and convenient discharge of the condensed water. The discharge method not only avoids motor burnout due to that blades of the fan are hindered by the condensed water but also provides a discharge outlet of the condensed water.
