Abstract

A washing machine including a drying function for drying laundry items received therein is provided. The washing machine may include an air circulating device that circulates air through a tub of the washing machine and heats air for re-supply to the tub, and an air discharge device that discharges a portion of moist air from the tub to an outside of the tub.

First claim

What is claimed is:

1. A washing apparatus, comprising:
a cabinet including a rear panel having a through hole extending therethrough;
a tub provided in the cabinet and including:
a circumferential wall, wherein an inner surface of the circumferential wall defines a condensing channel and a condensing space that receives moist air discharged from a drum;
a rim that forms an opening in a front portion of the tub;
an air delivery pipe secured to an inlet opening formed in the rim through which hot air is introduced;
an air collection pipe that protrudes in a tangential direction from a rear portion of an upper side of the circumferential wall of the tub and collects air from the tub; and
a discharge duct formed as a pipe that passes through an outer circumferential surface of a rear side of the tub and spaced apart a predetermined distance from the air collection pipe to discharge the air from the inside of the tub,

the drum rotatably provided in the tub;
a drying duct connected between the air collection pipe and the air delivery pipe along an upper portion of the tub to form an air movement path for moving and circulating air of the tub from the air collection pipe to the air delivery pipe;
a fan installed between the air collection pipe and the drying duct to move the air,
a heater provided in the drying duct that heats the air received from the fan;
a connection member fixed in the through hole formed in the rear panel;
an exhaust pipe having a first end that communicates with the discharge duct and a second end that communicates with an interior of the connection member; and
a discharge pipe having a first end that communicates with an exterior of the connection member outside the washing apparatus and a second end that discharges some of the air from the tub to lower a relative humidity in the tub.

2. The washing apparatus of claim 1 , wherein the fan is disposed adjacent the air collection pipe upstream of the heater.
