Benefits of technology
[0013] The present invention has been conceived to solve the above-mentioned problems occurring in the prior art, and an aspect of the present invention is to provide an exhausting apparatus of a motor assembly having a developed noise prevention effect by improving material and structure of a housing enclosing a driving motor.
[0014] Another aspect of the present invention is to provide a vacuum cleaner wherein the noise incurred during air flow is reduced by applying the exhausting apparatus to a vacuum cleaner.
[0023] The motor housing, the noise prevention board and the noise prevention part may be made from materials robust to fire. In order to achieve the above aspects, there is provided a method of reducing noise caused by a motor assembly that generates a suction force, comprising: passing a first portion of air discharged from the motor assembly through a first porous material having a first density; passing a second portion of air discharged from the motor assembly through a second porous material having a second density that is different from the first density; and exhausting the first and second portions of air to atmosphere.
Problems solved by technology
The high power motor produces strong noise during driving thereof.
The polypropylene is appropriate for safety against fire, however, it cannot reduce the noise.

Embodiment Construction
[0038] Certain embodiments of the present invention will be described in greater detail with reference to the accompanying drawings.
[0039] In the following description, same drawing reference numerals are used for the same elements even in different drawings. The matters defined in the description such as a detailed construction and elements are nothing but the ones provided to assist in a comprehensive understanding of the invention. Thus, it is apparent that the present invention can be carried out without those defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.
[0040] An exhausting apparatus of motor assembly for generating a suction force can be used for various apparatuses which require suction force. For convenience of description, however, a vacuum cleaner will be explained wherein the exhausting apparatus of the motor assembly is applied as an exemplary example.

An exhausting apparatus of a motor assembly comprises a motor assembly generating a suction force and having an air outlet; a motor housing enclosing the motor assembly and having an air discharging opening for exhausting air via the air outlet; and a porous noise prevention board configured in the exhausting passage formed by the motor housing. The motor housing has a porous noise prevention part at least at a portion, and at least a part of air discharging from the air outlet passes through the noise prevention part. As such, a noise can be reduced when air is discharged.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of Korean Patent Application No. 2004-89836 filed on Nov. 5, 2004, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to an exhausting apparatus of a motor assembly and a vacuum cleaner, and more particularly, to an exhausting apparatus which discharges air from a motor assembly and a vacuum cleaner having the same. [0004] 2. Description of the Related Art [0005] Generally, a vacuum cleaner draws in dusts or contaminants into a dust-collecting area by a suction force generated by a driving motor of a driving chamber of a vacuum cleaner body. A high power motor with high RPM is used for the driving motor. The high power motor produces strong noise during driving thereof. As such, a structure for preventing noise is necessitated.
