The pulsator washing machine provided by the embodiment of the application comprises a door lock device 10, wherein a first lock body 102 rotates relative to a door lock main body 101 in the door lock device 10, so that after the first lock body 102 and a second lock body 103 are clamped, a box body assembly 20 and an upper cover assembly 30 of the pulsator washing machine can be locked, and the reliability is good when the box body assembly 20 and the upper cover assembly 30 are closed. In addition, since the driving circuit 104 in the door lock device 10 can drive the first lock body 102 to rotate relative to the door lock main body 101, automatic locking or automatic unlocking of the box assembly 20 and the upper cover assembly 30 can be realized without manual locking by a user, the efficiency of locking and unlocking is effectively improved, and the flexibility is high.

The scheme that this application embodiment provided has avoided because the user forgets to close the locking knob, and this rotary drum washing machine just begins to evaporate and boil and wash, leads to the risk that the user is scalded by the water among the rotary drum washing machine. In the embodiment of the present application, after the user covers the upper cover assembly 30 on the casing assembly 20, the control circuit 40 in the pulsator washing machine may send a locking instruction to the driving circuit 104 in the door lock device 10 as long as the user selects a heating washing program such as steaming washing. At this time, the first lock 102 of the door lock device 10 is engaged with the second lock 102, so that the casing assembly 20 and the upper cover assembly 30 of the pulsator washing machine are locked. Until the temperature reaches within normal acceptable limits for human body after washing is completed, the control circuit 40 may send an unlock command to the drive circuit 104. At this time, the first lock body 102 in the door lock device 10 is disengaged from the second lock body 102, so that the box assembly 20 is unlocked from the upper cover assembly 30, and the user can take the clothes by himself.
