During the reversal of the motor 7, the second straight hook 8 returns to its original position under the force of the second return spring.

Therefore, the top-opening drum washing machine of the present invention can automatically close the inner cylinder cover 31 after the user closes the outer cylinder cover 21, which simplifies the user's opening operation step and optimizes the user's use experience. Further, the top-opening drum type washing machine of the present invention also avoids the phenomenon that the inner cylinder cover 31 is caught in the outer cylinder 2 as the inner cylinder 3 rotates when the user forgets to close the inner cylinder cover 31.

In addition, in a feasible embodiment, the person skilled in the art can also make the second straight hook 8 firstly interfere with the first inner cylinder cover 311 and then close the outer cylinder cover 21 as needed. In this case, the outer cylinder cover 21 and the inner cylinder cover 31 can be closed at the same time 2. Further, when the second straight hook 8 is in contact with the first inner cylinder cover 311, the motor 7 stops rotating and maintains the current state. When the outer cylinder cover 21 and the inner cylinder cover 31 are completely closed and locked, the controller detects that the outer cylinder cover 21 is locked, reverses the motor 7, and returns the second straight hook 8 to the original position.

In another possible embodiment, those skilled in the art can also omit other structural components as needed, and only connect the motor 7 of the present invention to the outer cover 211 or the inner cover 212 to connect the output of the motor 7. The shaft is fixedly connected to the second straight hook 8. When the motor 7 is rotated through a certain angle, the second straight hook 8 is turned out of the outer cylinder cover 21 to abut against the first inner cylinder cover 311. When the outer cylinder cover 21 and the inner cylinder cover 31 are both closed and locked, the motor 7 The reversal causes the second straight hook 8 to be retracted into the outer cylinder cover 21.

In yet another possible embodiment, those skilled in the art can also omit other structural components, with the cylinder as the driving device, as needed. The second straight hook 8 is fixedly connected or integrally formed with the piston rod, and when the piston rod extends out of the cylinder of the cylinder, the second straight hook 8 can abut against the first inner cylinder cover 311. When both the outer cylinder cover 21 and the inner cylinder cover 31 are closed, the piston rod is retracted into the cylinder, and the second straight hook 8 is retracted into the outer cylinder cover 21.

Heretofore, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the drawings, but it is obvious to those skilled in the art that the scope of the present invention is obviously not limited to the specific embodiments. Those skilled in the art can make equivalent changes or substitutions to the related technical features without departing from the principles of the present invention, and the technical solutions after the modifications or replacements fall within the scope of the present invention.
