Abstract: Provided are a washing machine in which an auxiliary door can be safely and conveniently used, and a method of controlling the same. The auxiliary door through which laundry can be additionally put into the washing machine, is provided, and the auxiliary door can be safely locked/unlocked. Because an open/closed state of the auxiliary door can be indirectly determined through a locking/unlocking operation of the auxiliary door, even when a door opening/closing detecting device has broken down, the auxiliary door can be safely used. In addition, the auxiliary door is unlocked by default and conditions on which the auxiliary door is locked for safety if necessary, are minimized during an operation of the washing machine so that use convenience of the auxiliary door can be enhanced, and a locked state of the auxiliary door is maintained according to the amount of laundry so that the laundry can be safely put into the washing machine.

Abstract: 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.
