  • the present invention further provides a clothing processing machine capable of reducing the amount of fluff entering an air channel.
  • a clothing processing machine having a drying function wherein the clothing processing machine comprises a barrel of any type in the various embodiments above, and an air driving means can drive air through the filter screen from inside the barrel and then into an air channel downstream of the filter screen.
  • the clothing processing machine comprises a drum located in the barrel, and further comprises a controller configured to be able to run a drying program and a washing program, wherein, in the drying program, the air driving means is activated and air enters the air channel after passing through the filter screen from inside the barrel, and in the washing program, washing liquid enters the barrel and submerges at least part of the filter screen, the drum being driven to rotate and thereby driving washing liquid to scour the filter screen.
  • the filter screen of the barrel can intercept most of the fluff in drying air, reducing accumulation of fluff downstream of the filter screen, so that the clothing processing machine maintains a more stable drying effect.
  • the position of the filter screen is such that at least part of the filter screen is lower than the water level in the barrel in the washing program, further advantages also include the fact that washing water can flush fluff on the filter screen, and discharge it from the machine. In this way, the filter screen can be automatically cleaned, and the fluff is automatically discharged.
  • the fact that the filter screen is formed on the barrel by integrated injection molding not only reduces the number of installation steps but also results in neater edges, avoiding a situation where fluff and dirt are left behind on a mechanical installation structure, causing secondary contamination of clothing.
  • the use of a metal filter screen allows the mesh holes to be made finer, to capture a greater amount of finer fluff, and furthermore, the high temperature in the drying process makes the connection between the metal filter screen and the plastic barrel tighter and more secure.
  • the barrel comprises a cover forming part of the air channel
  • having the filter screen provided on the cover makes the overall union of the filter screen and the barrel more ingenious and simple.
  • a clothing processing machine 1 comprises a barrel 2, and a rotatable drum 3 located in the barrel 2.
