Benefits of technology

[0009] The present invention has been developed in order to solve the above problems in the related art. A first aspect of the present invention is to provide a motor assembly having a simplified configuration and a vacuum cleaner having the same.

Problems solved by technology

However, such a high output motor causes a large volume of noise when it is driven.
H01-268524 require the extra noise absorbing member to reduce noise, their structures are complicated and their manufacturing cost is high.
Also, although both disclosures can reduce a blade passing frequency (BPF) and the entire noise level, they do not effectively reduce a low frequency band noise.

Embodiment Construction

[0018] Hereinafter, a motor assembly and a vacuum cleaner having the same according to a non-limiting embodiment of the present invention will now be described with reference to the accompanying drawings. For reference, arrows in the drawings indicate an air flow direction.

[0019]FIG. 1 is a view illustrating a cleaner body in which a motor assembly according to a non-limiting embodiment of the present invention is mounted. Referring to FIG. 1, the cleaner body 10 may include a dust collecting chamber S1 and a motor chamber S2.

[0020] The dust collecting chamber S1 may be a space that may be partitioned from the motor chamber S2 by a partition 10a and may be formed in a front portion of the cleaner body 10. The dust collecting chamber S1 may have a dust collector to separate and collect dust. In this embodiment, a dust bag 11 may be provided as the dust collector. Instead of the dust bag 11, a single or multi-cyclone dust collecting apparatus (capable of being used repeatedly) may b...
