Abstract: A laundry treating apparatus comprising an induction module is disclosed. The laundry treating apparatus comprises a cabinet, a drum provided inside the cabinet and formed of a metal material for accommodating a treatment target, and an induction module spaced apart from an outer circumferential surface of the drum at a predetermined interval, inducing and heating the drum, wherein the induction module includes a base housing for accommodating a coil, and a cover housing forming a moving space of heat generated from the coil, jointed to an upper portion of the base housing, the cover housing includes a through portion for discharging the heat by passing through the cover housing up and down, and the cover housing forms a section upwardly inclined toward the through portion to move the heat generated from the coil along the inclined section and discharge the heat to the through portion. It is possible to prevent a temperature of the coil from being excessively increased in the induction module, and enhance durability and efficiency of the induction module by making sure of a structure for active discharge of heat generated from the coil.

Abstract: A cleaner according to the present invention comprises: a suction unit; a main body including a cyclone unit for separating dust from dust suctioned through the suction unit, and a dust container that stores dust separated in the cyclone unit below the cyclone unit; a filter unit which is disposed inside the cyclone unit and is for filtering the air in a process in which air, from which the dust has been separated, passes through; a movable unit movably disposed inside the cyclone unit and provided with a cleaning part for cleaning the outer circumference of the filter unit while moving; an operation unit disposed outside the main body and operated to move the movable unit; and a transmission unit passing through the main body and connecting the movable unit and the operation unit. The movable unit waits inside the cyclone unit at a standby position, which is a position at which the movable unit does not surround the circumference of the filter unit during the dust separation process. When the operation unit is operated, the movable unit moves, and the cleaning part removes dust from the outer surface of the filter unit. The movable unit includes a recess portion which is recessed in a direction away from the suction unit and at least a portion of which faces the suction unit.
