When the filter screen 12 needs to be cleaned, the cleaning assembly 15 can automatically clean the filter screen 12. The clothes treatment device is provided with the filter assembly 1, so that the filter screen 12 (refer to fig. 3) does not need to be manually cleaned, and the convenience of practical use is improved.

As shown in fig. 1, in an actual installation, it is preferable that the mounting hole is opened in the bottom of the front support 21. In this way, the impurity chips entrained in the drying gas can be brought into the filter assembly 1 as much as possible for filtering. The sundry chips are prevented from falling and depositing in the clothes drying cylinder between the filter components 1, and the cleanliness of sundry chip filtering is effectively improved.

specifically, after the filter assembly 1 is installed in the installation hole, the filter screen bracket 11 is attached to the inner wall of the installation hole. Therefore, an inner flow passage (not shown) communicating with the cavity 112 is opened on the inner wall of the mounting hole. The inner flow passage is preferably disposed below the filter screen support 11 so that the dry air introduced into the inner flow passage can pass through the side wall of the filter screen support 11 after being filtered by the filter screen 12, and finally flows to other parts of the laundry treating apparatus through the inner flow passage, and is introduced into the laundry dryer for reuse after being treated. In this way, a path along which the drying gas circulates is formed, and the drying gas circulates along the path to dry the laundry.

the above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
