Description

Clothes dryer including filter assembly Technical Field Various embodiments of the present disclosure relate to a filter disposed in a laundry dryer, and more particularly, to a laundry dryer including a filter assembly configured to reduce flow path resistance of drying air flowing inside. Background A laundry dryer is a home appliance for drying wet clothes using hot and dry air. Laundry dryers may be classified into gas dryers and electric dryers according to power sources, and may be classified into ventilated dryers and condenser dryers according to how moisture extracted from clothes is handled. The ventilating type dryer discharges the humid air flowing in from the drum to the outside through the extended exhaust duct, and the condenser type dryer dries the humid air from the drum through the heat exchanger and returns the dry air to the drum. The air circulated inside the laundry dryer through such a series of processes may be referred to as circulated air. In response to performing a drying process by the dryer, the circulated air may travel through the rotating drum, and the circulated air may dry clothes (also referred to as an object to be dried) placed in the drum. In this process, foreign substances such as dust or lint present in the object to be dried may flow together with the drying air. The filter assembly disposed on a path from the outlet of the drum to the heat exchanger may collect foreign materials flowing together with the dry air. When foreign matter accumulates above a threshold level in the filter assembly, air may not flow smoothly. Further, the flow of the circulated air may not be smooth due to the structure of a circulated flow path (which is a flow path through which the circulated air discharged from the drum moves) or due to the structure of a filter provided on the path. In other words, the flow path resistance that interferes with the movement of the circulated air may increase. Disclosure of Invention Technical problem to be solved According to various embodiments of the present disclosure, a filter assembly may be presented that minimizes flow path resistance by maximizing the cross-sectional area of the flow path of the filter assembly through which dry air travels. Technical proposal A laundry dryer according to an embodiment of the present disclosure may include a main body having a drum inside the main body and having a front panel having a first opening to the drum through which an object to be dried can be placed into the drum, a heat exchanger located on a base of the main body and through which air discharged from the drum travels to exchange heat with the heat exchanger, an outlet duct for guiding the air discharged from the drum to the base, and a filter assembly having a shape of a polyhedron having a width, a length and a height and one opening side, and configured such that air discharged from the drum and traveling through the heat exchanger is filtered by the filter assembly, wherein the width may be longer than a diameter of the first opening in the front panel and the length may be longer than a horizontal length of an outlet positioned at a start point of the outlet duct. The top side of the filter assembly may be open, and the filter assembly may further include a mesh member along a plurality of sides of the filter assembly other than the top side of the filter assembly, respectively, such that the plurality of sides include a surface formed by the mesh member. The front surface of the filter assembly may be inclined at a first angle relative to the lower surface of the filter assembly, and an upper portion of the front surface may be inclined adjacent to the front panel as compared to a lower portion of the front surface. The rear surface of the filter assembly may be inclined at a second angle with respect to the lower surface of the filter assembly, and a lower portion of the rear surface may be inclined adjacent to the front panel as compared to an upper portion of the rear surface. The first angle and the second angle may be 90 ° to 180 °. The front panel may include a second opening through which the filter assembly is movable and a cover configured to open and close the second opening. The width of the second opening may be greater than or equal to the width of the filter assembly, and the height of the second opening may be greater than or equal to the height of the filter assembly. The laundry dryer may further include a sealing member between the second opening and the cover, the sealing member may correspond to a periphery of the second opening, and the sealing member may be configured to seal the second opening in response to closing of the cover. A guide rail may be located on one side of the filter assembly and a base cover may be located on the base, and the base cover may include a guide plate that supports the guide rail when the filter assembly is located on the base. The guide rail may be located on the guide plate. The filter ass
