A washing machine and dryer heaving being improved duct structure thereof

Abstract

The present invention relates to a washing machine and dryer with an improved duct structure. A cabinet (100) forma an outer shell of the washing machine and dryer, and a tub (200) is installed within the cabinet (100). A drum (250) is rotatably installed within the tub (200). Since a drying duct (300) is installed in an upper portion of the tub (200) that is eccentric toward one side when viewed from the front of the tub, an internal space utilization of the cabinet (100) is enhanced and the equipment can be compact. The drying duct (300) is manufactured with two bodies that are a lower part (310) and an upper part (320) formed by extending a discharge part (330) from one end portion of the drying duct (300), so that the number of parts and the number of assemble processes are reduced and the productivity is improved. Since the discharge part and the lower part are formed in one body, it can prevent the damage and the air leakage, caused in a connection portion due to vibration, and the flowing noise caused by them. The discharge part (330) is extended to be slant in a rotation direction of the drum (250) and a guidance part is extended in a tangential direction with respect to a rotation direction of the drum (250) at one end portion of the discharge part (330), thus smoothly supplying air to the drum (250). A condensation duct (400) has one end connected to the drying duct (300) and the other end connected to an inside of the tub (200). A heater (800) is installed within the drying duct (300) and a circulation fan (350) is installed in the other end of the drying duct (300) to which the condensation duct is connected.

Description

technical field [0001] The present invention relates to a washing machine and a drying machine having a drying function, and more particularly to a washing machine and a drying machine having an improved duct structure through which moisture-removed drying air flows. Background technique [0002] A washing machine is generally a device that performs washing, rinsing, and dehydration operations to remove dirt from clothes through the interaction of detergent and water, and is generally classified into agitation type, pulsation type, and drum type washing machines. [0003] In the drum type washing machine among them, water, detergent, and clothes are loaded into a drum, the inner surface of which is equipped with a plurality of protruding turning ribs, and the drum rotates at a low speed. The laundry is then washed due to the impact caused when it is lifted up by the flip ribs and then dropped. The drum type washing machine has an advantage that the clothes are not damaged. ...

AI Technical Summary

Problems solved by technology

In this case, the joint between the lower part and the discharge part connected vertically to it is liable to become loose and create a gap

In extreme cases, the connection between the lower part and the discharge part may break

[0017] Fourth, because the vibration causes a gap at the joint between the lower part and the discharge part, the air flowing into the drying duct leaks and causes noise
