Abstract

The invention is suitable for the technical field of living electric appliances, and provides a noise reduction device and a clothes treatment device. The noise reduction device comprises a body and asound absorption piece, and a first cavity and a second cavity which do not directly communicate are formed in the two ends of the body; the sound absorption piece is arranged outside the body in a sleeving manner; and an annular flow channel is formed between the body and the sound absorption piece, and the annular flow channel communicates with the first cavity and the second cavity. The clothes treatment device comprises the noise reduction device, a fan and a fan sound insulation assembly. According to the noise reduction device, the first cavity and the second cavity which do not directly communicate are formed in the two ends of the body, and the first cavity communicates with the second cavity through arranging the annular flow channel. Thus, the contact area and the contact time of noise and the sound absorption piece are increased, the sound absorption piece can better play a role in sound absorption and noise reduction, the noise generated in the actual use process of the clothes treatment device is effectively reduced, and the use comfort of a user is improved.

Description

technical field [0001] The invention belongs to the technical field of household electrical appliances, and in particular relates to a noise reducing device and a clothes processing device. Background technique [0002] Existing clothes processing devices, such as a drum washing machine, are equipped with a fan. When washing clothes, the pressure generated by the fan drives the water flow to roll, thereby playing the role of washing clothes; or as a dryer, blowing air through the fan will Laundry drying. However, there is a large noise problem in practical applications, which affects the comfort of actual use. Therefore, it is necessary to carry out noise reduction treatment on the fan. [0003] Most of the existing noise reduction devices are to arrange sound-absorbing cotton on the pipe wall of the air inlet passage or the exhaust passage to reduce noise. In this way, the contact time between the noise and the sound-absorbing cotton is short, and the noise reduction eff...
