Problems solved by technology

[0005] However, due to the limited attachment area of ​​the sound-absorbing felt, the area of ​​the sound-absorbing felt is much smaller than the overall area of ​​the washing machine shell, so the noise of the motor can still radiate outward through other parts of the washing machine shell; The sound coefficient is limited, and the effect of reducing noise is not obvious

Abstract

The application discloses a sound-proof shield of a motor and an apparatus with a motor. The apparatus comprises a motor and a motor sound-proof shield. A composite sound-absorption layer is arranged inside the motor sound-proof shield and consists of a damping sound-absorbing layer, a perforated plate, sound-absorbing cotton and a sound insulation board. The space encircled by the sound insulation board and the perforated plate is filled with the sound-absorbing cotton; and the damping sound-absorbing layer is in contact with the outer side surface of the perforated plate. Because the composite sound-absorption layer is arranged inside the motor sound-proof shield, the motor sound-proof shield covers the outer side of the motor, and thus the motor is enclosed in the space formed by the motor sound-proof shield, the degree of outward radiation of noises of the motor can be reduced; with the composite sound-absorption layer, the sound absorption performance of the motor sound-proof shield can be improved and the volume of noises can be reduced, so that the noise value of equipment having the motor can be reduced.

Description

technical field [0001] The invention relates to the technical field of washing, in particular to a motor soundproof cover and a device with a motor. Background technique [0002] In many devices, a motor is used as a power output device, but the motor will generate a lot of noise during operation. Let's take a washing machine as an example. [0003] The vibration noise of the washing machine comes from the vibration sound and the mechanical operation transmission sound produced by the washing machine when it is washing and dehydrating. The motor is both the power source of the washing machine and the source of noise. Motor noise can be mainly divided into ventilation noise, electromagnetic noise and mechanical noise. For series motors, during high-speed dehydration, mechanical noise is particularly obvious due to the high-speed friction between the commutator and carbon brushes. [0004] In order to reduce noise, the existing solution is to attach attraction felts to the ...
