Abstract

A cleaner including a dust collection unit configured to separate dust from air through centrifugation is provided. The dust collection unit includes a dust collection case having an inlet through which air is introduced and an outlet through which the air is discharged, and a cyclone assembly located in the dust collection case to separate dust from the air introduced through the inlet. The cyclone assembly includes a dust separation housing having an inner space, configured to have a first introduction unit formed at a side surface thereof; and an air curtain generation member coupled to the dust separation housing at a lower part of the first introduction unit, configured to include an air curtain discharge unit arranged at one upper end thereof so that the air curtain discharge unit allows vertical airflow ascending along the first introduction unit to be discharged.

First claim

1 . A cleaner comprising:
a dust collection unit to separate dust from air through centrifugation, including: a dust collection case having an inlet through which air is introduceable and an outlet through which the air is dischargeable; and a cyclone assembly to separate dust from the air introduceable through the inlet, wherein the cyclone assembly includes:
a dust separation housing having an inner space, configured to have a first introduction unit formed at a side surface thereof, and
an air curtain generation member couplable to the dust separation housing at a lower part of the first introduction unit, configured to include an air curtain discharge unit arranged at an upper end thereof so that the air curtain discharge unit allows vertical airflow ascending along the first introduction unit to be discharged.

2 . The cleaner according to claim 1 , wherein the air curtain generation member further includes:
a second introduction unit through which air is introduced, at a lower end of the air curtain generation member, wherein the second introduction unit is formed to have a larger area than the air curtain discharge unit.

3 . The cleaner according to claim 2 , wherein the air curtain generation member is formed to have a larger cross-section with decreasing distance to a bottom part thereof.

4 . The cleaner according to claim 2 , wherein the air curtain discharge unit is arranged at a position where the air curtain discharge unit encloses a lower end of the first introduction unit.

5 . The cleaner according to claim 2 , wherein the first introduction unit includes a first filter member to separate dust from the air flowing into the dust separation housing.

6 . The cleaner according to claim 5 , wherein the second introduction unit includes a second filter member to separate dust from the air flowing into the air curtain generation member.

7 . The cleaner according to claim 2 , wherein the cyclone assembly includes:
an introduction pipe provided in an inner space of the dust separation housing, to include a first flow passage therein, a guide unit provided at one side of the introduction pipe, to allow the air moved through the introduction pipe to be discharged to an inner space of the dust collection case, and an airflow formation unit provided at one side of the guide unit in such a manner that the air discharged from the guide unit forms a swirling airflow.

8 . The cleaner according to claim 7 , wherein the cyclone assembly includes:
a second flow passage disposed between the introduction pipe and the dust separation housing, and a discharge outlet provided at one end of the dust separation housing, to communicate with the second flow passage,
wherein the discharge outlet is formed to communicate with the outlet of the dust collection case.

9 . A cleaner comprising:
a dust collection unit to separate dust from air introduceable through centrifugation, including:
a dust collection case having an inlet through which air is introduceable and an outlet through which the air is dischargeable, and
a dust separation unit to centrifugally separate the dust from the air by generating a swirling airflow,
wherein the dust separation unit includes:
a dust separation housing in which a first introduction unit to communicate with an inner space is provided at a side surface thereof, and
an air curtain generation member, coupable to the dust separation housing, to generate an ascending airflow rising along an outer circumference of the first introduction unit,
wherein the air curtain generation member provides the ascending airflow to prevent the swirling airflow generated in the dust collection case from moving to the first introduction unit.

10 . The cleaner according to claim 9 , wherein the air curtain generation member includes:
an air compression unit formed therein, an air curtain discharge unit provided above the air compression unit, and a second introduction unit provided below the air compression unit,
wherein a cross section of the second introduction unit is larger in size than the air curtain discharge unit.

11 . The cleaner according to claim 10 , wherein the air curtain generation member is formed to have a larger cross-section with decreasing distance to a bottom part thereof.

12 . The cleaner according to claim 10 , wherein the air curtain generation member is arranged at a position where the air curtain generation member encloses a lower end of the first introduction unit.

13 . The cleaner according to claim 10 , wherein the first introduction unit includes a first filter member configured to separate dust from the air flowing into the dust separation housing.

14 . The cleaner according to claim 13 , wherein the second introduction unit includes a second filter member configured to separate dust from the air flowing into the air curtain generation member.

15 . The cleaner according to claim 14 , wherein the first filter member is configured to filter out finer dust than the second filter member.

16 . The cleaner according to claim 14 , wherein each of the first filter member and the second filter member includes a mesh.

17 . The cleaner according to claim 1 , wherein the cyclone assembly is located in the dust collection case.

18 . The cleaner according to claim 9 , wherein the dust separation unit is is located in the dust collection case.

19 . The cleaner according to claim 9 , wherein one side of the air curtain generation is coupable to the dust separation housing,

20 . A dust collection unit to separate dust from air through centrifugation, including a dust collection case having an inlet through which air is introduceable and an outlet through which the air is dischargeable, and
a cyclone assembly to separate dust from the air introduceable through the inlet, wherein the cyclone assembly includes:
a dust separation housing having an inner space, configured to have a first introduction unit formed at a side surface thereof, and
an air curtain generation member couplable to the dust separation housing at a lower part of the first introduction unit, configured to include an air curtain discharge unit arranged at an upper end thereof so that the air curtain discharge unit allows vertical airflow ascending along the first introduction unit to be discharged.
