Abstract

A vacuum cleaner is provided, which includes a main body; a dust collection unit arranged in the main body to collect dusts from air that flows into the main body along an intake passage; and a suction unit arranged at a downstream that is lower than a location of the dust collection unit on the intake passage to provide a suction force, wherein the suction unit includes a suction force generator, an exhaust passage configured to switch a discharge direction of the air that has passed through the suction force generator at least twice, and a plurality of sound-absorbing members arranged on the exhaust passage to pass the air therethrough.

First claim

What is claimed is:

1. A vacuum cleaner comprising:
a main body;
a dust collector arranged in the main body to collect dust from air that flows into the main body along an intake passage; and
a suction device arranged at a downstream that is lower than a location of the dust collector on the intake passage to provide a suction force,
wherein the suction device includes:
a suction force generator,
a first housing configured to accommodate the suction force generator, and including a first discharge hole provided in a bottom surface of the first housing and discharging the air sucked from the suction force generator to an outside,
a second housing configured to accommodate the first housing, and including a second discharge hole provided in a side surface of the second housing and discharging the air that flows in from the first discharge hole to the outside,
a third housing provided separately from the main body and configured to accommodate the second housing, and including a third discharge hole provided in a side surface of the third housing and discharging the air that flows in from the second discharge hole to the outside,
a first sound absorbing member arranged in the bottom surface of the first housing, and
a second sound absorbing member arranged between the side surface of the first housing and the side surface of the second housing, wherein the second sound absorbing member is in contact with an outer surface of the first housing and an inner surface of the second housing.

2. The vacuum cleaner as claimed in claim 1 , wherein a first section is formed inside the first housing,
a second section is formed between the outer surface of the first housing and the inner surface of the second housing, and
the air that flows from the first section to the second section switches its flow direction.

3. The vacuum cleaner as claimed in claim 2 , wherein a direction of the air that flows through the first section is opposite to a direction of the air that flows through the second section.

4. The vacuum cleaner as claimed in claim 2 , wherein a length of the second section is longer than a length of the first section.

5. The vacuum cleaner as claimed in claim 2 , wherein a direction of the air that is discharged through the second discharge hole is different from a direction of the air that flows through the second section.

6. The vacuum cleaner as claimed in claim 1 , wherein the second discharge hole is arranged adjacent to a second opening of the second housing.

7. The vacuum cleaner as claimed in claim 6 , wherein the first and second discharge holes comprise a plurality of through-holes, and
the plurality of through-holes of the second housing are elongated holes that are formed to extend along an outer periphery of the second housing.

8. The vacuum cleaner as claimed in claim 1 , wherein the first sound-absorbing member covers the bottom surface of the first housing.

9. The vacuum cleaner as claimed in claim 1 , wherein the second sound-absorbing member surrounds the outer surface of the first housing to come in contact with the inner surface of the second housing.

10. The vacuum cleaner as claimed in claim 9 , wherein the second sound-absorbing member covers the second discharge hole.

11. The vacuum cleaner as claimed in claim 1 , further comprising a hitting noise reflector configured to cover a bottom surface of the second housing so as to reflect hitting noise of the air that is directed from the first discharge hole to the bottom surface of the second housing.

12. The vacuum cleaner as claimed in claim 1 , further comprising at least one anti-vibration member arranged between the suction force generator and the first housing to absorb vibration that is transferred from the suction force generator to the first housing.

13. The vacuum cleaner as claimed in claim 12 , wherein the anti-vibration member is arranged on one side of the first housing that is opposite to an intake hole of the suction force generator.

14. The vacuum cleaner as claimed in claim 1 , further comprising at least one anti-vibration member arranged between the first housing and the second housing to absorb vibration that is transferred from the first housing to the second housing.

15. The vacuum cleaner as claimed in claim 14 , wherein the anti-vibration member is arranged between a bottom surface of the second housing and a bottom surface of the first housing.

16. A vacuum cleaner comprising:
a main body;
a dust collector arranged in the main body to collect dust from air that flows into the main body along an intake passage; and
a suction device arranged at a downstream that is lower than a location of the dust collector on the intake passage to provide a suction force,
wherein the suction device includes:
a suction force generator,
a first housing configured to accommodate the suction force generator, including a first discharge hole provided in a bottom surface of the first housing, and providing a first exhaust passage configured to guide the air sucked from the suction force generator to the first discharging hole,
a second housing configured to accommodate the first housing, including a second discharge hole provided in a side surface of the second housing, and providing a second exhaust passage configured to guide the air that flows in from the first discharge hole to the second discharge hole,
a third housing provided separately from the main body and configured to accommodate the second housing, and including a third discharge hole provided in a side surface of the third housing and discharging the air that flows in from the second discharge hole to the outside,
a first sound absorbing member arranged in the bottom surface of the first housing, and
a second sound absorbing member arranged between the side surface of the first housing and the side surface of the second housing, wherein the second sound absorbing member is in contact with an outer surface of the first housing and an inner surface of the second housing, and

wherein the first and second exhaust passages are arranged to form a layer.

17. The vacuum cleaner as claimed in claim 16 , wherein the second housing further comprises a hitting noise reflector arranged between the first exhaust passage and the second exhaust passage to reflect hitting noise of the air of which a flow direction is switched.
