A washing machine and a control method therefor are disclosed. The washing machine according to the present invention comprises: a drum for receiving laundry; a drying unit for adjusting the temperature of air in the drum so as to dry the laundry; a filter unit for filtering lint generated from the laundry; a cleaning unit for cleaning the filter unit; and a control unit for controlling the cleaning unit such that the filter unit is periodically cleaned during rotation of the drum. Accordingly, the washing machine can reduce the amount of lint generated from laundry during a drying process. Further, the washing machine according to the disclosure periodically cleans a filter for filtering lint generated from laundry, so as to facilitate circulation of air in the drum during a drying process, thereby improving the drying efficiency.

Washing machine and control method therefor

An inner door assembly for a drum washing machine includes an inner door internal shell formed of plastic and including a rim portion and a projecting portion projecting from the rim portion; and an inner door external shell formed of metal and including a rim portion and a projecting portion corresponding to the rim portion and the projecting portion of the inner door internal shell, wherein the inner door external shell is combined not to be separated from the inner door internal shell.

A drainage control device for washing machines is disclosed. This device controls the drain port, provided at the bottom of a washing tub, thus draining water from the washing tub in accordance with an operational mode of a washing machine. This drainage control device includes a first drive means containing a working fluid and operated in response to a change in volume of the working fluid, and a second drive means connected to the first drive means and controlling inflow and outflow of the working fluid relative to the first drive means. The first drive means comprises a first cylinder containing the working fluid, a first piston reciprocating within the first cylinder, a heating means used for heating the first piston, and an actuation rod operated in conjunction with both the first piston and the heating means to open or close the drain port. This device is less likely to cause operational errors or operational noises regardless of long periods of use, and also has a simple construction, a reduced number of parts, and is produced at low cost due to the simple construction.
