Abstract
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.
Claims15
A vacuum cleaner comprising:
- a cleaner body having a dust-collecting chamber and a motor chamber;
- a brush assembly connected with the dust-collecting chamber in fluid-communication and having an inlet for contaminants-laden air;
- a motor assembly mounted in a widthwise direction within the motor chamber to generate a suction force and having an air outlet;
- a motor housing at least substantially enclosing the motor assembly and having a discharging opening to exhaust the air discharged from the air outlet;
- an exhausting passage formed at least in part by the motor housing;
- and
- a porous noise prevention board in the exhausting passage, wherein at least a portion of the motor housing comprises a porous noise prevention part, and at least a portion of the air from the air outlet passes through the porous noise prevention part.
A method of reducing noise caused by a motor assembly that generates a suction force, the method comprising:
- mounting the motor assembly in a widthwise direction;
- drawing air into the motor assembly in a lengthwise direction through a suction pipe;
- 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.
