Abstract

A fan motor apparatus for a vacuum cleaner is provided. The fan motor apparatus may include a fan motor, an outer casing surrounding at least a part of the fan motor, wherein the outer casing includes a discharge portion having a discharge port; and, a noise-absorbent member is supported by the discharge port such that the port is closed, wherein the noise-absorbent member changes its shape to form a leakage space when internal exhaust pressure of the fan motor exceeds a predetermined degree.

Claims

1. A fan motor apparatus for a vacuum cleaner, comprising:

a fan motor;

an outer casing surrounding at least a part of the fan motor, wherein the outer casing includes a discharge portion having a discharge port; and

a noise-absorbent member supported by the discharge port-portion such that the discharge port is closed when an internal exhaust pressure of the fan motor is below a predetermined degree, the noise-absorbent member changes its shape to form a leakage space when an internal exhaust pressure of the fan motor exceeds a predetermined degree, and wherein the discharge portion comprises a side frame formed on a side surface to support the noise-absorbent member, a support portion protruding from a lower inner portion of the side frame to support a lower surface of the noise-absorbent member, and at least one upper frame extending inward from the side frame to support an upper surface of the noise-absorbent member on an upper portion of the side frame.

2. The fan motor apparatus of claim 1, wherein the discharge port is formed at the side frame.

3. The fan motor apparatus of claim 2, wherein the side frame comprises at least one recessed portion extending downwardly from an upper portion.

4. The fan motor apparatus of claim 1, wherein the noise-absorbent member is returned to an original shape if the internal exhaust pressure of the fan motor is returned to a degree less than the predetermined degree.

5. The fan motor apparatus of claim 1, wherein the noise-absorbent member is made from a foamed member having an elastic resilience.
