Description

technical field

[0001] The invention relates to the technical field of washing machines, more specifically, to a noise reduction component and a washing machine. Background technique

[0002] As one of the three major pollutions today, noise pollution has seriously endangered the physical and mental health of consumers. With the development of washing machine product technology and the needs of human senses, noise quality has become a key indicator of washing machine design. The noise of the washing machine mainly comes from the vibration sound and mechanical noise produced by the washing machine when it is washing and dehydrating. Caused by the assembly of washing machine components or the interaction between components.

[0003] At present, in order to improve the noise quality of the washing machine, sound-absorbing felt is usually pasted on both sides of the washing machine’s casing. Since the sound-absorbing felt is made of inorganic fiber material, its porous charact...
