Abstract

Proposed is an air conditioning assembly of a vehicle seat. The air conditioning assembly includes a housing provided in a vehicle seat, in which air flows in an internal space of the housing and the air is discharged to a seating surface of the seat, and an air cleaner provided in the internal space of the housing and configured to selectively sterilize or deodorize the air flowing in the internal space of the housing by rotating according to an air conditioning mode.

First claim

What is claimed is:

1. An air conditioning assembly of a vehicle seat, the air conditioning assembly comprising:
a housing disposed in a seat, the housing being configured to have air flowing in an internal space of the housing and to discharge air to a seating surface of the seat; and
an air cleaner disposed in the internal space of the housing, the air cleaner being configured to selectively sterilize or deodorize the air flowing in the internal space of the housing and to rotate according to an air conditioning mode,
wherein in the internal space of the housing, the housing includes an expansion portion having a shape in which a flow path expands and contracts along an air flow direction, wherein the air cleaner is disposed in the expansion portion, and
wherein a plurality of blocking parts are disposed on one side of the expansion portion in a width direction of the expansion portion and configured to block a part of the expansion portion, wherein the air cleaner is disposed between the plurality of blocking parts.

2. The air conditioning assembly of claim 1 , further comprising:
an actuator disposed on one side of the housing, the actuator being configured to operate when switching to the air conditioning mode and thereby rotate the air cleaner.

3. The air conditioning assembly of claim 1 , wherein the air conditioning mode includes a ventilation mode and an air purification mode, and the air cleaner is configured to sterilize or deodorize the air flowing in the internal space of the housing in the air purification mode.

4. The air conditioning assembly of claim 3 , wherein the air cleaner is configured to change an area of the air cleaner in contact with the air flowing in the internal space of the housing according to the air conditioning mode, wherein an area in contact with the air in the air purification mode is larger than an area in contact with the air in the ventilation mode.

5. The air conditioning assembly of claim 3 , wherein the housing is configured to change an amount of the air discharged to the seating surface of the seat according to the air conditioning mode, wherein an amount of the air discharged in the air purification mode is smaller than an amount of the air discharged in the ventilation mode.

6. The air conditioning assembly of claim 1 , further comprising:
a light source disposed in the internal space of the housing and configured to radiate light toward the air cleaner from a point adjacent to the air cleaner.

7. The air conditioning assembly of claim 6 , wherein the air cleaner has a coating having a material containing a photocatalyst, the air cleaner being configured to sterilize or deodorize the air by the light radiated from the light source reaching the photocatalyst.

8. The air conditioning assembly of claim 1 , wherein a discharge port is disposed at an end of the housing, the discharge port being configured to discharge the air that has passed through the air cleaner in the internal space of the housing to the seating surface of the seat.

9. The air conditioning assembly of claim 8 , wherein the discharge port has an elastic body or a corrugated tube shape, the discharge port being configured to be extended or reduced depending on a position of the seating surface of the seat.
