Drying system 2 still includes being located filter screen 30 below drainage portion 20, and this drainage portion 20 is located filter screen 30's windward side 303 one side, and drainage portion 20 extends from lower extreme 302 of filter screen 30 towards the second port 272 direction of induced air portion 27, and this drainage portion outwards extends to the outer main drainage channel of cylinder that induced air portion set up outward through second port 272, and this main drainage channel includes the main drainage mouth that is located outer cylinder bottom. The filter screen 30 can be vertically arranged, that is, the upper end 301 and the lower end 302 of the filter screen 30 are located on the same vertical line; or the filter screen 30 may be disposed obliquely with respect to the vertical direction, the lower end 302 of the filter screen 30 is relatively close to the second port 272 (or the drum) of the air guiding portion 27, and the upper end 301 of the filter screen 30 is relatively far away from the second port 272 (or the drum) of the air guiding portion 27, so that the cleaning water along the plane of the filter screen 30 can pass through the second port 272 along the inner wall of the air guiding portion 27 from the lower end 302 of the filter screen 30, then flow into the outer drum 31, and be discharged from the main water discharge port at the bottom of the outer drum 31, which not only facilitates discharging the cleaning water of the cleaning device, but also enables the cleaning water to be discharged before entering the air duct in the air guiding portion 27, thereby facilitating maintaining the stability of the.
Referring to fig. 5 to 7, the cleaning device 28 and the air induction portion 27 may be fixed by assembly. The air inducing portion 27 protrudes outward to form a fixing support 2721 for fixing the cleaning device, the fixing support 2721 is formed with a mounting through hole 2722 for mounting the cleaning device, the mounting through hole 2722 is communicated with an inner cavity of the air inducing portion 27, a part of the water inlet pipe of the cleaning device 28 is located at the mounting through hole 2722, and the cleaning device 28 has a holding portion which is in holding fit with the fixing support 2721. The inner wall of the air induction portion 27 further has a fixing recess 2722 for receiving a portion of the screen fixing portion 33, and the fixing recess 2722 may be integrally formed in the inner wall of the air induction portion 27. The clamping part of the cleaning device is in sealing fit with the fixed support 2721 of the induced draft part 27. Specifically, the cleaning device has a fixing rib 294 engaged with the fixing support 2721, the fixing rib 294 is formed by extending outward from an outer surface of the cleaning device, and the fixing rib 294 is in sealing engagement with the fixing support 2721. The mounting through hole 2722 is an annular hole, and a ring of annular grooves 2723 are formed in the periphery of the mounting through hole 2722 and used for placing sealing rings to prevent air leakage. Specifically, when the cleaning device is installed, the sealing ring is installed in the annular groove 2723, then the lower end of the fixing rib 294 of the cleaning device is fixedly connected to the fixing bracket 2721 of the air inducing portion 27, and the fixing rib 294 is firmly fixed to the air inducing portion 27 by providing the fastening member 2724. The fixing bracket 2721 and the fixing recess 2722 may be disposed on the same central axis, the fixing recess 2722 extends to form a protrusion 2723 toward the second port 272 of the air inducing portion 27, and a blocking opening 2724 for the washing water is formed between the protrusion 2723 and the filter screen 30, and the protrusion is used for blocking the washing water with a large water pressure from being splashed into the inner drum from the filter screen to affect drying of the laundry in the inner drum 32.
