When the drum-type clothes dryer is in operation, the driving motor 64 can drive the cleaning member 62 to rotate, wherein the driving motor 64 can drive the cleaning member 62 to rotate in the direction opposite to the rotation direction of the drying drum 2, and can also drive the cleaning member 62 to rotate in the same direction as the rotation direction of the drying drum 2, only in this case, the rotation speed of the cleaning member 62 needs to be greater than or less than the rotation speed of the drying drum 2, so as to generate relative movement between the cleaning member 62 and the drying drum 2, and therefore, the cleaning member 62 can clean lint on the outer wall of the drying drum 2.

It should be noted that the driving motor 64 can also be mounted on the top and/or bottom plate of the box 1, and such flexible adjustment and change can be achieved without departing from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

Similarly to the passive lint cleaning device, the active lint cleaning device also includes a position switching member 63, and the mounting member 61 is connected to a driving motor 64 by means of the position switching member 63, and the position switching member 63 can switch the mounting member 61 between positions close to and away from the drying drum 2 so as to bring the cleaning member 62 into contact with or separate from the outer wall of the drying drum 2. Wherein the position switching member 63 is an electromagnetic switching member.

It should be noted that the position switching member 63 can also be configured as a stepping motor, the stepping motor is mounted on the output shaft of the driving motor 64, the output end of the stepping motor is connected with the mounting member 61, the stepping motor can drive the mounting member 61 to move, so as to switch the mounting member 61 between the positions close to and far away from the clothes drying cylinder 2, and the like, and the adjustment and change of the specific structural type of the position switching member 63 do not depart from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

With continued reference to fig. 5, similar to the passive lint cleaning device, the cleaning member 62 of the active lint cleaning device also includes a connecting arm 621 and bristles 622 disposed on the connecting arm 621, wherein one end of the connecting arm 621 is connected to the mounting member 61. Wherein the connecting arm 621 and the mounting member 61 can be fixedly connected or integrally provided.

With continued reference to fig. 5, similar to the passive lint cleaning device, the number of the connecting arms 621 of the active lint cleaning device is also 3, and the connecting arms are circumferentially arranged along the mounting member 61. The connecting arm 621 is preferably arranged along a curved shape in the radial direction, such as an arc shape or an S shape, and by such arrangement, the length of the connecting arm 621 can be increased as much as possible in a limited space, so that more bristles 622 can be arranged on the connecting arm 621, and the cleaning capability of the cleaning member 62 can be improved.

With continued reference to fig. 5, the mounting member 61 is a disk 61. Of course, the mounting member 61 can be provided in other configurations, such as a mounting bracket, a mounting plate, etc., and such modifications and changes to the specific configuration of the mounting member 61 without departing from the spirit and scope of the present invention should be limited only by the scope of the present invention.

Finally, it should be noted that, because the air inlet 211 is disposed on the rear wall 21 of the drying cylinder 2, and the thread scraps are mainly attached to the outer wall of the rear wall 21, the thread scrap cleaning device 6 of the present invention mainly cleans the outer wall of the rear wall 21, and of course, if thread scraps are also attached to the outer wall of the side wall of the drying cylinder 2, the specific structure of the thread scrap cleaning device 6 can be adjusted accordingly, so that the thread scrap cleaning device 6 can also clean the outer wall of the side wall of the drying cylinder 2.

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.
