- FIG. 11 shows a control block diagram of the washing machine shown in FIG. 1 .
- the washing machine 1 may include a controller 60.
- the control unit 60 may be electrically connected to the display unit 14 .
- the control unit 60 may receive the user's command from the display unit 14 .
- the controller 60 may be electrically connected to the circulation pump 110 .
- the controller 60 may be electrically connected to the drain pump 120 .
- the controller 60 may be electrically connected to the filter driving device 140 .
- the controller 60 may control the circulation pump 110 based on information received from the display unit 14 .
- the controller 60 may control the drain pump 120 based on the information transmitted from the display unit 14 .
- the controller 60 may control the filter driving device 140 based on information received from the display unit 14 .
- FIG. 12 is a control flowchart of the washing machine shown in FIG. 1 .
- the washing machine 1 may perform a washing cycle.
- the circulation pump 110 may be operated.
- Wash water in the tub 20 may be circulated by the circulation pump 110.
- the washing machine 1 may perform a rinsing operation after performing a washing operation.
- the drainage pump 120 and the filter driving device 140 may be operated.
- S104 Accordingly, when wash water discharged to the outside of the washing machine 1 passes through the filter 131 and is filtered, the filter blade 136 rotates inside the filter 131. Thus, the filter 131 can be prevented from being clogged with dirt.
- the washing machine 1 may perform a spin-drying cycle after performing a rinsing cycle.
- the drainage pump 120 and the filter driving device 140 may be operated.
- S106 Accordingly, when wash water discharged to the outside of the washing machine 1 passes through the filter 131 and is filtered, the filter blade 136 rotates inside the filter 131. Thus, the filter 131 can be prevented from being clogged with dirt.
- the washing machine and the laundry treatment device include filter blades, it is possible to prevent the filter from being clogged.
- filter blades are detachably mounted to filters in washing machines and laundry treatment devices, filter management can be facilitated.
