Clothes dryer utilizing suction duct extending into drum interior

A clothes dryer, comprising:

• a case;
• a drum rotatably supported in the case and having a space for drying clothes within said drum;
• a suction duct being connected to a first side of the drum for supplying air to said drum for drying clothes;
• an extension duct extending from the suction duct into the drum, wherein air supplied from the suction duct into the drum flows through said extension duct;
• and
• an exhaust duct connected to a second side of the drum for exhausting air within said drum to an exterior of the case;
• wherein the drum has two air suction ports connected to the suction duct on a rear side of the drum and the extension duct is connected to a first air suction port of said two air suction ports.

A clothes dryer comprising:

• a case;
• a drum having
• a rotatable body supported in the case, and
• a front plate and a rear plate engaged with stationary front and rear sides of the body;
• a suction duct being connected to the rear plate of the drum supplying air to said drum for drying clothes;
• an extension duct extending from the suction duct into the drum, wherein air supplied from the suction duct into the drum flows through said extension duct toward a rotational center of said drum;
• and
• an exhaust duct connected to the front plate of the drum for exhausting air to an exterior of said case, wherein the front plate of said drum includes a cylindrical portion extending a certain length in a longitudinal direction of the body from an outer circumferential surface of the drum, said cylindrical portion having an exhaust port at a lower portion thereof, and said exhaust duct is connected to the exhaust port of the cylindrical portion.

• a drum having
• a rotatable body supported in the case, and
• a front plate and a rear plate engaged with stationary front and rear sides of the body;
• a suction duct being connected to the rear plate of the drum supplying air to said drum for drying clothes;
• an exhaust duct being connected to the front plate of the drum for exhausting air to an exterior of the case;
• and
• an air suction port formed on the rear plate of said drum and connected to the air suction port, wherein the air suction port is formed having a tapered shape increasing in area as the air suction port extends away from a rotational center of the drum.

A clothes dryer, comprising:

• a case;
• a drum rotatably supported in the case and having an interior space for drying clothes within said drum;
• a suction duct being connected to a first side of the drum supplying air to said drum for drying clothes;
• an extension duct extending from the suction duct into the drum, wherein air supplied from the suction duct into the drum flows through a plurality of air holes within said extension duct toward a rotational center of said drum;
• a first exhaust duct being connected to a second side of the drum for exhausting air within said drum to the outside of the case;
• and
• a second exhaust duct diverging from the first exhaust duct for exhausting a portion of the air exhausted from the drum to a front side of the suction duct.
