Benefits of technology
[0014] An object of the present invention is to provide a drum type washing machine with a heat-drying function, which can minimize an airflow resistance caused by an uneven portion formed on a connection tube when high temperature and humidity air in a drum is exhausted to an external side.
[0015] Another object of the present invention is to provide a drum type washing machine with a heat-drying function, which is designed to prevent foreign objects such as naps from being accumulated in a connection tube when high temperature and humidity air in a drum is exhausted to an external side.
[0019] According to the present invention, the damage of the connection tube connecting the tub to the exhaust duct is not damaged by vibration generated during washing, rinsing and spin-drying processes and the flow resistance of the air flowing along the connection tube can be minimized.
[0020] In addition, by improving an internal structure of the connection tube, the airflow may be improved by minimizing the accumulation of foreign objects such as nips in the connection tube.
[0021] Furthermore, pressure loss in the connection tube can be minimized by improving the structure of the connection tube.
Problems solved by technology
At this point, since the vibration is transmitted to the connection tube, the connection tube may be damaged.
However, the uneven portion causes the change of the flow of the air flowing along the connection tube.
That is, due to the uneven portion of the connection tube, pressure loss is incurred in the connection tube, whereby the wind run is reduced in proportion to the pressure loss.
In addition, foreign objects such as naps are caught on the uneven portion of the connection tube, deterioration the airflow.

A drum type washing machine includes a tub, a case receiving the tub, a connection tube having a first end connected to the tub to define a passage along which air flows from the tub, the connection tube being provided with an uneven portion having a plurality of peaks and valleys and a plurality of straight sections connecting the peaks to the valleys, the peaks and valleys being asymmetrically formed, and an exhaust duct connected to a second end of the connection tube to exhaust air flowing along the connection tube to an external side.
Description
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a drum type washing machine, and more particularly, to a connection pipe assembly of a drum type washing machine, which connects a tub to an exhaust duct that exhausts high temperature and humidity air in a drum to an external side during a drying process. [0003] 2. Description of the Related Art [0004] Generally, a washing machine is designed to remove dirt from the laundry using surface activation of detergent dissolved in washing water as well as water current generated by the rotation of a drum. [0005] In recent years, a drum type washing machine performing the washing process by allowing laundry to collide with washing water by lifting and dropping the laundry has been widely used. The drum type washing machine has advantages of providing less damage, increasing washing efficiency and washing a large amount of laundry at a time. [0006] In addition, as a drum type washing machine...
