Provided is a drain pump which comprises: a collecting tank for condensed water; a main body of the drain placed inside the collecting tank; an operating part which is installed on one side of the main body; a pumping unit which pumps the condensed water inside the collecting tank according to the operation of the operating part; a switching part which operates the operating part according to the amount of the condensed water collected inside the collecting tank. The switching part comprises a float which moves upward or downward according to buoyancy of the condensed water collected inside the collecting tank, and one end of the switching part is formed to penetrate the float, and the other end is equipped with at least one magnet. A pumping switch of the drain pump comprises: a lifting rod which moves upward with the float when the float moves upward by a predetermined distance; and a pumping lever which rotates to a direction of the position of the magnet when the lifting rod moves upward. An elastic member of the drain pump provides elasticity to the pumping lever such that the pumping lever moves to the opposite direction of the position of the magnet. |
