Patent ID: 7275399

Claim:
A condensing apparatus of a washing and drying machine comprising: a casing that forms an accommodating space therein; a tub installed in the casing; an air duct having one end connected to the tub to thus introduce air into the tub; a blower fan that blows air along the air duct; and a heater that heats air of the air duct before being introduced into the tub, wherein the condensing apparatus further comprises: a condensing duct having one end connected to a lower region of the tub and another end extending upwardly; a condensate water supplying duct connected to an upper region of the condensing duct to supply condensate water into the condensing duct; a condensate water dispersing portion provided with a plurality of dispersion holes formed along a circumferential direction of the condensing duct at spaced intervals and arranged at an outlet side of the condensate water supplying duct along a flow direction of the condensate water, to dispersedly drop condensate water supplied from the condensing water supplying duct; and a chamber having an expanded flow section area that is greater than that of the condensing duct, having a lower end connected to the condensing duct and an upper end connected to an inlet of the blower fan, and provided with a condensate water supplying opening to which the condensate water supplying duct is coupled at one side thereof, wherein the lower end of the chamber is below an upper end of the condensate water dispersing portion.
