[0002] Existing pulsator washer-dryers are divided into water condensation type and direct discharge type. Among them, the direct discharge all-in-one machine, during the drying process, first allows the incoming hot air to act directly on the clothes in the drum to take away the moisture in the clothes, so as to achieve drying of the clothes, and then allows the hot air with moisture to be directly discharged to the outside through the exhaust port, thereby reducing the moisture content inside the washing machine, thereby improving the drying effect of the clothes.

[0003] The existing patent announcement number is: CN215518025U, and the name of the patent is "An air outlet assembly for a washing machine", comprising a mounting base plate, an annular enclosure plate is provided on the upper surface of the mounting base plate, a mounting cavity is formed between the annular enclosure plate and the mounting base plate, an air outlet pipe is provided at the bottom of the mounting base plate, a ventilation hole connected to the air outlet pipe is provided on the mounting base plate, a rubber layer is provided in the inner cavity of the ventilation hole, a through hole is provided in the rubber layer, an air outlet suction fan is fixed in the mounting cavity, an air inlet end of the air outlet suction fan is provided with a plug-in tube inserted into the through hole in the rubber layer, an air outlet opposite to the air outlet end of the air outlet suction fan is provided on the annular enclosure plate, and an air outlet suction fan for drawing air outwards is provided at the air outlet, thereby effectively improving the rate at which the washing machine discharges gas to the outside, thereby effectively avoiding the accumulation of moisture containing a large amount of water inside the washing machine, and ensuring that the washing machine has a high drying efficiency.

[0004] In the above-mentioned prior art, since some clothes are prone to produce lint during the process of blow-drying, if the exhaust speed is directly increased by a suction fan, it is impossible to avoid the lint being discharged from the air outlet into the room driven by the strong airflow, resulting in the need to further clean the lint fallen on the ground, and the use effect is not good. Therefore, the present application provides an exhaust duct to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide an exhaust assembly to solve the existing problem that since some clothes are prone to produce lint during the process of blow-drying, if the exhaust speed is directly increased by a suction fan, it is impossible to avoid the lint being discharged from the air outlet into the room under the drive of the strong airflow, resulting in the need for further cleaning of the lint fallen on the ground, and the use effect is not good. Therefore, the present application provides an exhaust duct to meet the demand.

[0006] In order to solve the above-mentioned technical problems, the utility model provides the following technical solutions: an exhaust assembly, comprising a mounting frame and a fan and an air suction channel arranged at both ends of the mounting frame, the exhaust channel being detachably fixed on the side wall of the fan, and a positioning groove being provided on the side wall of the fan, wherein a fastening frame is provided on the outer wall of the fan, a filter is embedded and fixed at one end of the exhaust channel away from the fan, a groove is provided at the other end of the exhaust channel, and a plurality of lint collection grooves are provided at the center of the exhaust channel, and a positioning component that is engaged with the positioning groove is fixed in the groove.

[0007] Optionally, the air suction channel has a U-shaped structure, and air suction pipes are installed on both sides of the bottom end surface of the air suction channel.

[0008] Optionally, a check valve is installed at the top of the air suction channel, and the top of the check valve is fixedly connected to the mounting frame.

[0009] Optionally, an air inlet slot is provided at the top of the mounting frame, the fan is fixed to the side wall of the air inlet slot, and the fan is provided with an air inlet port connected to the air inlet slot.

[0010] Optionally, an exhaust port is provided on a side wall of the fan, and an exhaust cavity connected to the exhaust port is provided in the hollow cavity of the exhaust channel.

[0011] Optionally, the positioning assembly includes an elastic plate fixed to the inner wall of the groove and a positioning portion fixed to the top of the elastic plate.

[0012] Optionally, a side wall of the positioning portion is provided with an inclined groove, and the positioning portion is fitted and inserted into the positioning groove.

[0013] Compared with the prior art, the utility model has at least the following beneficial effects:

[0014] In the above scheme, a mounting frame is provided, and a fan and an air suction channel are respectively fixed at both ends of the mounting frame. The fan sucks out the lint and steam generated by drying in the washing and drying machine through the air suction channel, and discharges them from the exhaust channel after being sucked out. A filter is embedded and fixed in the side wall of the exhaust channel to block the lint in the air. At the same time, the blocked lint is affected by aerodynamics and remains in the lint collection groove on the exhaust channel, which is convenient for blocking and collecting the lint in the washing and drying machine and avoids the lint being discharged from the exhaust assembly.

[0015] A positioning groove is provided on the side wall of the fan, a groove corresponding to the positioning groove is provided on the exhaust passage, an elastic plate is fixed on the inner wall of the groove, and a positioning part is provided on the top of the elastic plate. When the exhaust passage is inserted into the fan, the inner wall of the fan abuts against the inclined groove at the top of the positioning part, and the positioning part is squeezed during the abutment process to cause the elastic plate to undergo elastic deformation until the exhaust passage is completely inserted into the fan. The elastic force of the elastic plate drives the positioning plate to be inserted into the positioning groove, thereby keeping the exhaust passage fixed, and the positioning block is squeezed from the outer wall of the fan to move it out of the positioning groove, thereby separating the exhaust passage from the fan, making it easy to install and disassemble the exhaust passage, and improving the convenience of cleaning the fluff in the fluff collection groove of the exhaust passage.

The fan 2 sucks out the fluff in the washing and drying machine and the steam generated by drying through the suction channel 5, and discharges them from the exhaust channel 3 after being sucked out. A filter 14 is embedded and fixed on the side wall of the exhaust channel 3, and the filter 14 blocks the fluff in the air. At the same time, the blocked fluff is affected by aerodynamics and remains in the fluff collecting groove 13 on the exhaust channel 3, which is convenient for blocking and collecting the fluff in the washing and drying machine and avoiding the situation where the fluff is discharged from the exhaust assembly.

[0031] like Figure 3 Figure 4 As shown, a groove 15 is provided at the other end of the exhaust passage 3, and a plurality of lint collecting grooves 13 are provided at the center of the exhaust passage 3. A positioning assembly that is engaged with the positioning groove 12 is fixed in the groove 15.
