Vacuum cleaner

A vacuum cleaner having a motor chamber inside a cleaner body for mounting a motor assembly that generates a suction force at a dust suction port, the cleaner body having a discharge port for guiding air discharged from the motor chamber to the outside of the cleaner body, the motor chamber comprising:

• an air discharge opening in fluid communication with the discharge port;
• and
• a path extension member disposed between the motor assembly and the air discharge opening, wherein the edges of the path extension member are spaced apart from an inner wall of the motor chamber by a predetermined distance to thereby form a detour path,
• wherein the air discharged from the motor assembly is guided in a circuitous manner by the path extension member so as to be passed through the detour path before reaching the air discharge opening,
• wherein a distance between the inner wall of the motor chamber and the respective edges of the path extension member is less than a distance between the inner wall of the motor chamber and the air discharge opening,
• wherein the motor chamber further comprises a first partition having an air suction opening connected to the dust suction opening and disposed in the cleaner body;
• and a second partition having the air discharge opening and disposed in the cleaner body between the first partition and the discharge port,
• wherein the path extension member is a third partition being connected to a first support member extending from the second partition and spaced apart from the second partition by a predetermined distance, and
• wherein the second partition is removably inserted in a slide groove formed on a portion of an inner wall of the cleaner body.
