Background technique

During the operation of the dryer, the fluff and lint on the clothes inevitably flow with the drying air and are blocked by the lint filter device and remain on the lint filter device. The fluff and lint accumulate online with the use of the dryer. The debris filtering device blocks the flow of dry air, which reduces the drying efficiency of the dryer and deteriorates the drying effect.

In order to solve this problem, in the prior art, the lint filter device is usually set as a detachable structure. After the clothes dryer has been used for a period of time, the filter device needs to be removed for cleaning, or the filter device needs to be cleaned by spraying water through the cleaning equipment. This ensures the normal operation of the dryer.

The Chinese invention patent with application number CN201210575631.7 discloses a lint filtering device, including a first lint filtering layer, a second lint filtering layer and three lint filtering layers, the first lint filtering layer and the second lint filtering layer The filter layers are interlocked and installed under the door body of the front air duct at the air outlet of the drum of the dryer.
