Abstract

There are provided an air leakage preventing structure and an air cleaner having the same. The air leakage preventing structure includes: a partition unit having an inlet opening formed on one side thereof to allow air to be introduced therethrough and having a rib formed to be protruded from the circumference of the inlet opening; an air blowing fan coupled to the partition unit and rotating to allow air to be introduced through the inlet opening; a motor unit connected to the air blowing fan to rotate the air blowing fan; and an air guide unit connected to the rib formed to be protruded from the partition unit to form an outlet opening, and preventing air leakage when air introduced through the net opening flows out through the outlet opening.

First claim

The invention claimed is:

1. An air leakage preventing structure comprising:
a partition unit having an inlet opening formed on one side thereof to allow air to be introduced therethrough and having a rib formed to be protruded from the circumference of the inlet opening;
an air blowing fan coupled to the partition unit and rotating to allow air to be introduced through the inlet opening;
a motor unit connected to the air blowing fan to rotate the air blowing fan; and
an air guide unit connected to the rib formed to be protruded from the partition unit to form an outlet opening, and preventing air leakage when air introduced through the inlet opening flows out through the outlet opening; and,
wherein the rib is protruded from one side of the partition unit, and
wherein the air guide unit has a connection portion that is coupled to the rib from the direction opposing the one side of the partition unit, and
wherein the connection portion has a bent shape so as to closely contact the one side of the partition unit and one surface of the rib, respectively.

2. The air leakage preventing structure of claim 1 , wherein the connection portion provided in the air guide unit is bent to have an ‘L’ shape.

3. The air leakage preventing structure of claim 1 , wherein the connection portion contacts closely with an outer surface of the rib.

4. The air leakage preventing structure of claim 1 , wherein the rib has a shape corresponding to a shape of the air guide unit.

5. The air leakage preventing structure of claim 1 , wherein the air guide unit has a fastening unit formed on one side thereof and coupled to the partition unit.

6. An air cleaner comprising:
an air blowing unit having the air leakage preventing structure of claim 1 ;
a housing in which the air blowing unit is disposed; and
a filter unit disposed within the housing and purifying air introduced to the interior of the housing by the air blowing unit.
