Motor cover assembly and vacuum cleaner with same

Abstract

The invention discloses a motor cover assembly and a vacuum cleaner having the same. The motor cover assembly includes: a motor cover, in which a chamber for accommodating a motor is defined, and the motor cover has an air inlet and an air outlet communicating with the chamber; A sound-absorbing assembly, the sound-absorbing assembly is arranged in the chamber, and the sound-absorbing assembly includes: a micro-perforated plate, the micro-perforated plate is provided with a plurality of micro-perforations through its thickness direction, and the plurality of micro-perforations are spaced apart from each other; the back plate, At least one back cavity is provided on the back plate, and each back cavity has a communication port, the micro-perforated plate is arranged on the side of the back plate provided with the communication port, and the communication port of each back cavity is opposite to at least one micro-perforation, so that Each back chamber is communicated with at least one microperforation. According to the motor cover assembly of the embodiment of the present invention, the noise generated when the motor is in operation can be better reduced without affecting the aesthetics and sense of technology of the overall appearance of the product.

Description

technical field [0001] The invention relates to the technical field of vacuum cleaners, in particular to a motor cover assembly and a vacuum cleaner with the motor cover assembly. Background technique [0002] Vacuum cleaners are a common household appliance, but their noise seriously affects user experience. The motor is the noise source of the vacuum cleaner. If the noise from the motor can be reduced, the noise level of the vacuum cleaner will be greatly improved, and the user experience of the vacuum cleaner will be improved. The motor cover is the structure of the discharge motor, which is very important for reducing the noise transmitted by the motor. [0003] The vacuum cleaners in the related art reduce the noise transmitted from the motor from the motor cover by wrapping the sound-absorbing cotton on the motor cover. Wrapping the motor with sound-absorbing cotton for noise reduction has the following disadvantages: the motor is prone to heat, and if the motor is w...

AI Technical Summary

Problems solved by technology

Wrapping the motor with sound-absorbing cotton for noise reduction has the following disadvantages: the motor is prone to heat, and if the motor is wrapped with sound-absorbing cotton, the heat will not be easily discharged, which will easily cause the temperature of the motor to be too high and affect its life; the appearance of the sound-absorbing cotton is relatively Unsightly, affecting the appearance and sense of technology of the vacuum cleaner; sound-absorbing cotton is a ready-made product, and cannot be specially designed according to the spectral characteristics of motor noise to achieve better sound-absorbing effect
