When the washing machine normally works, in the process that washing water enters the outer barrel from the inner barrel 1, a part of the washing water in the inner barrel 1 of the washing machine enters the outer barrel through the water passing holes 5 on the flange plate 3, a part of the washing water enters the outer barrel of the washing machine through the through holes on the flange plate 3, a large amount of thread scraps are wrapped by the washing water entering the outer barrel through the water passing holes 5, the thread scraps are blocked at the lower side of the flange plate 3 by the through holes on the flange plate 3 when the washing water circulates back into the inner barrel, the thread scraps in the inner barrel 1 of the washing machine are greatly collected at the lower side of the flange plate 3 after circulation for many times, when the washing machine enters a drainage procedure, the washing water in the inner barrel 1 of the washing machine passes through the flange plate 3 due to gravity, at the moment, the washing water in the inner barrel flows out through the water passing holes 5 and the filtering holes 6 arranged on the flange plate 3, the washing water washes the flange plate 3, and the thread scraps accumulated at the lower side of the flange plate 3 flow into a drainage pipeline along with the washing water and are discharged out of the washing machine.
In the embodiment, the inner barrel bottom of the washing machine is of an annular structure, a hollow area coaxial with the inner barrel bottom is arranged on the inner barrel bottom, and the flange plate is arranged in the hollow area and is formed by injection molding together with the inner barrel bottom; the flange 3 is provided with water holes and filtering holes, so that the flange 3 has a thread scrap filtering function, the flange 3 directly replaces a filter, the filter is not required to be arranged at the bottom 2 of the washing machine, and after the filter is not arranged, a sufficient gap is not required to be reserved between the flange 3 and the filter in the assembling process, so that the space utilization rate between the inner barrel 1 and the outer barrel is improved; the flange 3 replaces a filter, so that a filtering system of the washing machine is simplified, and the assembly complexity is reduced; meanwhile, the inner barrel bottom 2 and the flange 3 are integrally formed by injection molding, so that the manufacturing process is simplified, the time for assembling the inner barrel bottom 2 and the flange 3 is saved, and the trouble in the assembling process is eliminated.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
