The utility model discloses a drainage component and an air conditioner. The drainage component comprises a body part, wherein the section of the body part in the length direction is wavy, a plurality of wave crest profile lines and a plurality of trough profile lines are formed in the width direction of the body part, and the widths of the connecting surfaces of the adjacent wave crest profile lines and the trough profile lines gradually increase from a first end to a second end in the width direction of the body part. The drainage component can be applied to the air conditioner for drainage. The drainage component can drive air flow to be mixed with main air flow to form mixed air flow through the main air flow. If the drainage component is applied to an air outlet of an indoor unit of the air conditioner, the driven peripheral air flow can be mixed with heat exchange air flow, the temperature difference of the air flow blown from the air outlet and indoor air can be reduced, the comfort degree of outlet air is improved, and the circulation speed of indoor air is improved.
