Abstract: A drain pump and a clothes dryer having a drain pump are provided. The drain pump may include a pump motor; an impeller including a hub, an impeller shaft that extends from a center of the hub and is connected to a rotational shaft of the pump motor, and at least one blade that extends from an outer circumferential surface of the impeller shaft; a housing including an impeller hole, through which the impeller may pass, and a space in which the pump motor may be accommodated; and a pump case coupled to a bottom surface of the housing. The pump case may have a suction hole to suction in cleaning water. The suction hole may be defined at a position corresponding to the impeller, and the pump case may include a shaft shield that extends from an edge of the suction hole in a central direction of the suction hole or toward a central portion of the suction hole to cover a lower end of the impeller shaft.

Abstract: A defrosting apparatus comprises a heater case comprising a heat pipe seating part formed to extend from one surface thereof in a recessed shape and a heater receiving part formed to extend to be parallel with the heat pipe seating part. The defrosting apparatus also includes a heater which is mounted in the heater receiving part so as to emit heat when power is applied thereto, a heat pipe which has a flow path through which a working fluid filled therein flows, which has a part seated on the heat pipe seating part, and which is disposed to be adjacent to a cooling pipe of an evaporator such that heat is radiated to the cooling pipe of the evaporator by means of the working fluid at a high temperature which is heated by the heater and then is transferred, and a holder which is detachably coupled to the heater case so as to cover the heat pipe seated on the heat pipe seating part.
