Further, the magnet 5 can be disposed on the first inner cylinder cover 32 at any feasible position, such as the free end of the first inner cylinder cover 32 and the position close to the side wall of the outer cylinder 2, as required by those skilled in the art. Still further, one skilled in the art can also arrange one magnet 5 on each of the first inner cylinder cover 32 and the second inner cylinder cover 33, and arrange two reed switches 4 at corresponding positions on the outer side of the outer cylinder 2, as required.

The closing detection control method of the present invention will be described in detail with reference to fig. 7 and 8.

As shown in fig. 7, the method for detecting and controlling the closing of the cover of the present invention mainly comprises:

step S110, detecting the on-off state of the reed switch 4;

and step S120, judging whether the inner cylinder covers (32, 33) are closed or not based on the detected on-off state of the reed switch 4.

Step S110 and step S120 are illustrated below with reference to fig. 8.

In step S201, a user manually presses a lid closing button provided on the top-loading drum washing machine. Since the arrangement of the cover-closing button is a conventional technical means in the art, it will not be described herein too much.

In step S202, the automatic lid closing device drives the first inner cylinder lid 32 and the second inner cylinder lid 33 to rotate in the closing direction.

In step S203, whether the reed switch 4 is on is detected while the first inner cylinder cover 32 and the second inner cylinder cover 33 are rotating. When detecting that the reed switch 4 is switched on, executing step S204; when it is detected that the reed switch 4 is not turned on, execution continues to step S203.

In step S204, after the reed switch 4 is turned on, it is determined whether the on time of the reed switch 4 is longer than 2S. It should be noted that the distance that the magnet 5 triggers the reed switch 4 is not a fixed value, but a range. When the magnet 5 moves to within a certain distance around the reed switch 4, the magnet 5 can trigger the reed switch 4. Therefore, it takes 2 seconds to ensure that the inner cover is closed in place. Furthermore, when the inner tub cover is manually closed, it is also necessary to leave a time of 2 seconds to ensure that the user takes his hands out of the washing machine. It will be understood by those skilled in the art that the value of greater than 2S can also be set to greater than or equal to 2S. In addition, those skilled in the art can select any other feasible time value instead of 2S according to actual needs, for example, 1S, 1.5S, 2.5S, and the like.

And step S205, when the on time of the reed switch 4 is detected to be more than 2S, the upper cover 12 is automatically closed under the action of the driving motor.

In step S206, while step S205 is executed, i.e., while the upper cover 12 is being closed, the current on-off state of the reed switch 4, i.e., whether the reed switch 4 is kept in the on state, is detected.

In step S207, when the reed switch 4 is in the on state, the upper cover 12 continues to be closed until the upper cover 12 is completely closed.

And step S208, when the reed switch 4 is disconnected, the top-opening type drum washing machine sends out alarm prompt information to remind that the inner drum cover is not closed or the washing machine breaks down.

In step S209, the closing of the upper cover 12 is suspended while the top-loading drum washing machine gives an alarm. After the failure is eliminated, step S203 is executed, or a person skilled in the art may continue to execute step S201 or step S202 as needed.

It can be understood by those skilled in the art that when the inner cylinder cover is manually closed, steps S201 and S202 are removed. When the upper cover 12 is manually closed, step S205 is changed to manually close the upper cover 12, and step S209 is optionally changed to disable the upper cover 12 from being closed.

Based on the above description of the closing detection control method, it can be understood by those skilled in the art that when the outer cylinder 2 includes an outer cylinder cover, the sequence of the operation of the upper cover 12 in steps S201 to S209 may be replaced by the operation of the outer cylinder cover, and the upper cover 12 is closed after the outer cylinder cover is closed. Alternatively, the upper lid 12 and the outer cylinder lid may be closed in synchronization.

In addition, the invention also provides a cover closing detection control system which comprises the reed switch 4, the magnet 5 and the controller. The controller is in communication connection with the reed pipe 4, and is used for controlling relevant components of the top-opening drum washing machine to execute the steps S110 and S120, and the steps S201 to S209 according to the on-off state of the reed pipe 4. The reed switch 4 can be replaced by any other feasible proximity switch, such as a hall switch or a hall element; the magnet 5 may be any feasible magnet, such as a rubidium magnet or triiron tetroxide, and the magnet 5 may also be replaced by any feasible triggering means, such as a metal sheet.

Through the above description, those skilled in the art can understand that the top-loading drum washing machine of the present invention can detect whether the inner drum cover is closed in real time from the time when the outer drum cover and/or the upper cover 12 starts to be closed to before the washing machine starts to operate, so as to avoid the problem that the inner drum 3 cannot rotate because the inner drum 3 is clamped in the outer drum 2 by the inner drum cover which is not closed.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
