Abstract

A ventilation seat of a vehicle is proposed. The ventilation seat includes a ventilation duct assembly mounted to a seat of the vehicle and configured to suck indoor air and to discharge air toward a vehicle room or a surface of the seat, an air cleaning assembly arranged in an air flow path of the ventilation duct assembly and configured to clean air passing through the air flow path in operation thereof, and a controller configured to operate the ventilation duct assembly in operation of an air cleaning mode of the vehicle to generate an air flow flowing through the seat, and configured to operate the air cleaning assembly to allow the air flow of the ventilation duct assembly to clean air in the vehicle.

First claim

What is claimed is:

1. A ventilation seat of a vehicle, the ventilation seat comprising:
a ventilation duct assembly mounted to a seat of the vehicle and configured to suck air and to discharge the air toward a vehicle room or a surface of the seat;
an air cleaning assembly disposed in an air flow path of the ventilation duct assembly and configured to clean the air passing through the air flow path in operation thereof; and
a controller configured to operate the ventilation duct assembly in operation of an air cleaning mode of the vehicle to generate an air flow flowing through the seat, and configured to operate the air cleaning assembly to allow the air flow of the ventilation duct assembly to clean air in the vehicle,
wherein the air cleaning assembly includes a catalytic converter configured to clean the air passing through the air flow path when light is emitted in the air flow path, and a light source assembly disposed on an inner wall of the air flow path to face the catalytic converter and configured to emit light to the catalytic converter, and
wherein the air cleaning assembly includes an expansion portion disposed in the air flow path of the air cleaning assembly in a direction in which the air flows, the expansion portion being shaped to enable that the air flow path expands and contracts, and wherein the catalytic converter is disposed at the expansion portion.

2. The ventilation seat of claim 1 , wherein the ventilation duct assembly comprises a blower disposed at an end thereof, and the controller is configured to control the blower to operate the ventilation duct assembly to suck the air and discharge the air to the vehicle room or the surface of the seat.

3. The ventilation seat of claim 1 , wherein the catalytic converter has a material containing a photocatalyst, and the air cleaning assembly is configured to clean the air as the light emitted from the light source assembly reaches to the photocatalyst.

4. The ventilation seat of claim 1 , wherein the light source assembly comprises at least one light source, and the at least one light source is configured to emit light to an entire surface of the catalytic converter that faces the light source assembly.

5. The ventilation seat of claim 1 , wherein the light source assembly comprises a plurality of light sources disposed on an inner wall of the expansion portion, and the catalytic converter is disposed in a width direction of the air flow path of the air cleaning assembly.

6. The ventilation seat of claim 1 , wherein the ventilation duct assembly comprises an inlet configured to introduce the air therethrough from the vehicle room, a first outlet configured to discharge the air therethrough into the vehicle room, and a second outlet configured to discharge the air therethrough toward the surface of the seat, wherein the air cleaning assembly is disposed in the inlet or the first outlet.

7. The ventilation seat of claim 1 , wherein a heat conductor is disposed in the air flow path of the ventilation duct assembly, the heat conductor being configured to divide the air flow path and to heat or cool air passing through each of divided air flow paths, wherein each of the divided air flow paths is connected to the vehicle room or the surface of the seat.

8. The ventilation seat of claim 1 , wherein the controller is configured to detect whether an occupant is seated on the seat by using a seating sensor disposed in the seat, and when seating of the occupant on the seat is detected, the controller is configured to receive the air cleaning mode from the occupant, and the controller is configured to operate the ventilation duct assembly or the air cleaning assembly in response to the air cleaning mode.

9. The ventilation seat of claim 8 , wherein when seating of the occupant on the seat is not detected, the controller is configured to operate the ventilation duct assembly and the air cleaning assembly to clean indoor air of the vehicle.

10. A ventilation seat of a vehicle, the ventilation seat comprising:
a ventilation duct assembly mounted to a seat of the vehicle and configured to suck air and to discharge the air toward a vehicle room or a surface of the seat;
an air cleaning assembly disposed in an air flow path of the ventilation duct assembly and configured to clean the air passing through the air flow path in operation thereof; and
a controller configured to operate the ventilation duct assembly in operation of an air cleaning mode of the vehicle to generate an air flow flowing through the seat, and configured to operate the air cleaning assembly to allow the air flow of the ventilation duct assembly to clean air in the vehicle,
wherein the controller is configured to detect whether an occupant is seated on the seat by using a seating sensor disposed in the seat, and when seating of the occupant on the seat is detected, the controller is configured to receive the air cleaning mode from the occupant, and the controller is configured to operate the ventilation duct assembly or the air cleaning assembly in response to the air cleaning mode, and
wherein when seating of the occupant on the seat is not detected, the controller is configured to operate the ventilation duct assembly and the air cleaning assembly to clean indoor air of the vehicle.
