Washing machine having a condensing duct

Abstract

A washing machine includes a drum and a condensing duct that communicates with the drum. The condensing duct includes an air inlet unit, a condensing unit and an air outlet unit which are connected sequentially. A condensed water jetting member is provided inside the condensing unit and a backward flow blocking guide is provided inside the condensing unit. The condensing unit has a flow width larger than the air inlet unit and the air outlet unit.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This invention is based on and claims priority from Korean Patent Applications No. 2004-0092507 filed on Nov. 12, 2004, and No. 2004-0093878 filed on Nov. 17, 2004, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference. BACKGROUND OF INVENTION [0002] 1. Field of Invention [0003] The present invention relates to a washing machine, and more particularly, to a washing machine having an improved structure of a condensing duct. [0004] 2. Description of the Related Art [0005] Generally a washing machine is an appliance to wash the laundry with the use of mechanical power, which is classified into several kinds of washing machines according to washing mechanisms. Especially, a drum-type washing machine refers to a kind of washing machine, which washes the laundry with impacts generated when the laundry is dropped downward by rotating a washing tank 360 degrees while using a smal...

AI Technical Summary

Benefits of technology

The present invention provides a washing machine that can prevent the condensed water from flowing backward and enhance the scattering efficiency of the condensed water. This is achieved by providing a condensing duct with a backward flow blocking guide and a condensed water collecting unit that is protruded to collect the backward flowing condensed water. The condensing duct has a larger flow width than the air inlet and outlet units, and an auxiliary condensed water collecting unit can be added. The dryer version of the invention also includes these features. Overall, the invention improves the performance and efficiency of the washing machine.

Problems solved by technology

However, the drum-type washing machine as described above has a limitation in blocking the condensed water flowing backward by the internally circulated air from being flown into the inside of the drum, resorting only to the elevation limiting projection provided on the internal wall face of the condensing duct.

In addition, the condensed water collecting projection is partially mounted on a side of the condensing duct and scatters the condensed water which is flowing down from the elevation limiting projection, thereby failing to produce a relatively high scattering effect of the condensed water.
