Abstract

A drawer type air cleaner having increased maintenance convenience is provided. The drawer type air cleaner includes a door that is configured to open or close an opening of filter receiving cavity formed in air cleaner body that suctions exterior air and discharges fresh air and a filter disposed in the filter receiving cavity and configured to filter out foreign substances from the exterior air and convert the exterior air into fresh air. The filter having a packing is disposed in the filter receiving cavity and thus provides an airtight seal between the filter and the filter receiving cavity. A filter protector is interlocked with an operation of closing the door to convert the filter from an incompletely coupled state when the filter disposed in the filter receiving cavity and is unable to compress the packing into a fully coupled state to a state when the filter compresses the packing.

First claim

What is claimed is:

1. A drawer type air cleaner having increased maintenance convenience, comprising:
a door configured to open or close an opening of a filter receiving cavity formed in an air cleaner body that suctions exterior air and discharges fresh air;
a filter disposed in the filter receiving cavity and configured to filter out foreign substances from the exterior air and convert the exterior air into fresh air, wherein the filter includes a packing in a state in which the filter is disposed in the filter receiving cavity, and provides an airtight seal between the filter and the filter receiving cavity; and
a filter protector configured to be interlocked with an operation of closing the door to convert the filter from an incompletely coupled position when the filter disposed in the filter receiving cavity is not able to compress the packing into a fully coupled state in which the filter compresses the packing,
wherein the filter protector includes a positioning rib which is comprised of a base protrusion and a manipulation protrusion; and a locking handle which is comprised of a locking protrusion,
wherein the manipulation protrusion includes a push-up body which is configure to push the handle upward, and the support body which is configured to support the handle, and
wherein the push-up body is configured to push the locking protrusion using push force generated when the door is closed, wherein a vertical component of the push force is configured to push the locking protrusion upward so as to rotate in the locking direction.

2. The drawer type air cleaner of claim 1 , wherein the filter protector includes:
the positioning rib disposed on an interior side of the door; and
the locking handle rotatably coupled to a side surface of the filter to enable the filter to compress the packing onto an interior surface of the filter receiving cavity.

3. The drawer type air cleaner of claim 2 , wherein the positioning rib protrudes from the door toward a front surface of the filter, and the locking handle includes a rod shaft coupled to the side surface of the filter and a handle positioned on the front surface of the filter.

4. The drawer type air cleaner of claim 1 , wherein
the manipulation protrusion is bent from the base protrusion at about 90 degrees, and
wherein the manipulation protrusion is configured to convert by closing the door, a position of the handle from an incomplete manipulation position with uncompressed packing to a full manipulation position.

5. The drawer type air cleaner of claim 4 , wherein the base protrusion and the manipulation protrusion form an “L” shape.

6. The drawer type air cleaner of claim 1 , wherein the push-up body and the support body that are divided from each other by a stopper.

7. The drawer type air cleaner of claim 1 , wherein the locking protrusion includes a positioning depression configured to receive the push-up body, and an interior inclined surface that contacts the push-up body and is supported by the support body.

8. The drawer type air cleaner of claim 7 , wherein each of the interior inclined surface and the support body has an identical inclined surface.

9. The drawer type air cleaner of claim 8 , wherein an inclination angle of the inclined surface is an acute angle.

10. The drawer type air cleaner of claim 2 , wherein the positioning rib and the locking handle include two positioning ribs and two locking handles that are disposed in pairs at positions adjacent to each other.

11. The drawer type air cleaner of claim 1 , wherein the air cleaner body includes an air cleaner sub-body configured to receive the exterior air.

12. The drawer type air cleaner of claim 1 , wherein the door is a hinged door with a door hinge and is coupled to the air cleaner body.

13. The drawer type air cleaner of claim 1 , wherein the filter includes:
filter paper configured to filter out foreign substances from the exterior air; and
a filter casing filled with the filter paper to maintain a shape and durability of the filter paper with the packing disposed on the filter casing.

14. An intake system, comprising:
a drawer type air cleaner as defined in claim 1 that includes a positioning rib formed on a hinged door disposed on an air cleaner body that suctions exterior air and discharges fresh air, and
a locking handle disposed in the air cleaner body and disposed on a filter configured to filter out foreign substances from the exterior air; and
an intake manifold supplied with the fresh air formed by filtering out foreign substances from the exterior air introduced into the drawer air cleaner.

15. A vehicle comprising:
an intake system configured to supply to an engine fresh air formed by filtering out foreign substances from exterior air introduced into a drawer type air cleaner as defined in claim 1 , wherein the drawer type air cleaner includes a positioning rib formed on a hinged door disposed on an air cleaner body that suctions the exterior air and discharges the fresh air; and
a locking handle disposed in the air cleaner body and disposed on a filter configured to filter out foreign substances from the exterior air.

16. The vehicle of claim 15 , wherein the drawer type air cleaner includes a mounting bracket, wherein the drawer type air cleaner is coupled by the mounting bracket to the engine compartment in which the engine and the intake system are provided.
