Abstract
Provided is an air flow structure for a dryer, which includes a drying fan, and an air guide having a bent and inclined shape so as to guide flow of a circulation air discharged by the drying fan. This air flow structure improves air circulation flow in the dryer, reduces noise generated in the drying procedure, and increases air volume introduced into a drying duct.
Claims20
An air flow structure of a dryer, comprising:
- a drying drum;
- a back cover mounted to a rear of the drying drum to protect the drying drum;
- a drying fan mounted to a side of the back cover to inhale circulation air;
- and
- an air guide mounted to a position spaced apart from an outer circumference of the drying fan as much as a predetermined distance to guide flow of the circulation air inhaled by the drying fan, the air guide having a bent portion so as to divide the flow of the circulation air into two directions.

An air flow structure of a dryer, comprising:
- a back cover;
- a drying fan mounted to a lower portion of the back cover in order to inhale circulation air discharged from a drying drum;
- an air guide including a bent portion mounted to a side of the drying fan to divide the circulation air discharged from the drying fan into two parts, a seat rib having a bent bottom so as to be closely adhered to the back cover, and at least one combination hole through the seat rib;

An air flow structure of a dryer, comprising:
- a drying fan;
- an air guide having a bent and inclined shape so as to guide flow of circulation air discharged from the drying fan;
- an air-sealing guide for connecting lower ends of the air guide so that the circulation air is guided upward;
