Structure for supplying hot air in drum type washing machine and operation control method thereof

Abstract

Structure for supplying hot air to a drum washing machine, and operation control method thereof, in which uniform introduction of hot air deep into an inside of a drum is made possible for enhancing drying capability and efficiency. For this, a drum washing machine includes a tub for holding washing water, a drum rotatably mounted in the tub, for introducing laundry therein, a drying heater for heating air being supplied to an inside of the drum, a drying duct forming a flow passage for supplying hot air heated by the drying heater to the inside of the drum, a fan for forced supply of the hot air heated by the drying heater to the inside of the drum, a hot air inlet at a front side of the drum for supplying the hot air to the inside of the drum, and a humid air recovery opening at a rear side of the drum for recovering humid air from the inside of the drum, and the operation control method of a drum washing machine includes the step of supplying hot air to an inside of the drum while rotating the drum at a speed equal to, or higher than a speed enough to keep the laundry in the drum attached to, and not fall off from, the inside surface of the drum in progressing a drying cycle.

Description

[0001] This application claims priority from Korean Application Nos. P2004-0010412 and P2004-0010413 filed on February 17, 2004, the contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a drum type washing machine, and more particularly to a structure for supplying hot air, wherein the hot air can be uniformly and deeply introduced into the inside of the drum in order to improve drying capacity and efficiency; and also to a method of controlling operation . Background technique [0003] Generally, among washing machines, there are mainly top loading type agitation type washing machines and drum type washing machines (generally called drum washing machines) having a drum arranged horizontally. [0004] As mentioned above, since the drum is arranged in the horizontal direction, the drum washing machine performs washing by causing the clothes put in the drum to rise and fall during the rotation of the drum. [0005] ...

AI Technical Summary

Problems solved by technology

[0020] Therefore, since the hot air is exhausted from the drum 30 before the hot air is fully used for drying in the drum, the drying performance and efficiency are impaired, and unnecessary energy needs to be input, resulting in waste of energy.

[0021] In short, for the main flow path of the hot air in the prior art drum washing machine, since the hot air cannot reach the clothes located far from the hot air inlet, the clothes cannot be dried uniformly, thereby reducing the drying performance, requiring Drying for a long time, so the drying efficiency is also reduced
