Fig. 4 is a partially enlarged schematic view of fig. 3.

Referring to fig. 2 to 4, the filter assembly 4 is used for filtering the air flowing in the cylinder 2 and the air duct 31, so as to remove the lint in the air. The filtering component 4 is arranged in the cylinder body 2 and is arranged at the air outlet 24. Therefore, the air in the cylinder 2 can be filtered by the filter assembly 4, so that the air can enter the air duct 31 after the lint is removed, and the lint is prevented from adhering to the fan 33 and the heater 32 in the air duct 31.

In some embodiments, the filter assembly 4 includes a filter screen 41 and a rotating shaft 42. The rotating shaft 42 is provided in the cylinder 2 and below the air outlet 24. One end of the filter screen 41 is rotatably fitted over the rotating shaft 42.

Therefore, when the fan 33 is turned on, the wind force of the laundry care cavity 20 entering the condensing cavity 25 through the rear wall of the inner drum 22 and the wind force of the condensing cavity 25 entering the air outlet 24 can both provide an assisting force for the rotation of the filter screen 41.

In some embodiments, the filter screen 41 and the air outlet 24 are both disposed near the rear wall of the outer tub 21. When the fan 33 is turned on, the end of the filter screen 41 away from the rotating shaft 42 can rotate under the action of the wind and abut against the rear wall of the outer cylinder 21, so as to shield or cover the air outlet 24, as shown in fig. 4. When the fan 33 is turned off, the filter screen 41 can rotate reversely under the action of gravity, and a gap 43 is formed between the lower end of the filter screen 41 and the rear wall of the outer cylinder 21, and the fluff between the filter screen 41 and the air outlet 24 can automatically fall through the gap 43, as shown in fig. 6.

In some embodiments, a side of the air outlet 24 close to the rear wall of the inner cylinder 22 is provided with a blocking wall 211 extending downward, and the blocking wall 211 is provided on the peripheral side of the air outlet 24 and formed by extending downward from the inner wall of the outer cylinder 21. The rotation shaft 42 is disposed below the blocking wall 211, and an end portion of the filter screen 41 connected to the rotation shaft 42 is provided with a stopper 411 extending upward. When the lower end of the filter screen 41 rotates downward under the action of gravity, the limit portion 411 at the upper end of the filter screen 41 can abut against the blocking wall 211, so that the gap 43 between the filter screen 41 and the rear wall of the outer cylinder 21 can maintain a specific width.

In some embodiments, the position-limiting portion 411 is disposed at an angle with respect to the main body of the filter screen 41, and the size of the gap 43 between the filter screen 41 and the rear wall of the outer cylinder 21 can be adjusted by adjusting the size of the angle between the position-limiting portion 411 and the main body of the filter screen 41 and adjusting the length of the filter screen 41, so that the flock on the upper side of the filter screen 41 can smoothly fall down, and the filter screen 41 can smoothly rotate, thereby smoothly shielding or covering the air outlet 24.

Referring to fig. 1 to 6, in some embodiments, the fan 33 is disposed at an end of the air duct 31 close to the air outlet 24, and the fan 33 is disposed opposite to the air outlet 24, so as to increase the wind force at the air outlet 24, so that the air in the clothes care cavity 20 can smoothly enter the air duct 31, and the filter screen 41 can smoothly rotate around the rotating shaft 42 to be shielded at the air outlet 24. In some embodiments, the fan 33 may adopt a centrifugal fan 33, an air inlet end of the centrifugal fan 33 is connected to the air outlet 24, and an air outlet end of the centrifugal fan 33 faces the other end of the air duct 31, so as to effectively ensure that the air outlet 24 has sufficient wind power.

In some embodiments, cleaning assembly 5 includes a spray head 51 and a communication tube 52. The shower head 51 is provided inside the outer tub 21, and the shower head 51 is disposed toward the filter net 41. The nozzle 51 is used for spraying water to the filter screen 41, and further washing the lint adhered to the filter screen 41, so that the lint can be smoothly dropped from the filter screen 41.

In some embodiments, the spray head 51 is provided on the rear wall of the outer tub 21. When the fan 33 is turned on, the end of the filter 41 away from the rotating shaft 42 can abut against the rear wall of the outer cylinder 21 under the influence of wind, and the nozzle 51 is located above the position where the filter 41 abuts against the rear wall of the outer cylinder 21. Therefore, no matter whether the fan 33 is turned on or not, and no matter whether the filter screen 41 is at any position within the rotation range, the nozzle 51 can smoothly spray water to the filter screen 41, and the lint can be effectively ensured to smoothly fall off from the filter screen 41.
