Abstract

The present invention relates to a photocatalytic device and a vehicle air conditioner including the same and, more specifically, to a photocatalytic device and a vehicle air conditioner including the same, and compared with a conventional photocatalytic device, the photocatalytic device readily protects, from external contaminants, electronic elements of a substrate at which a light source for emitting ultraviolet light is provided, and increases structural stability by changing a method for connecting the substrate and a connector with each other.

First claim

The invention claimed is:

1. A photocatalytic device comprising:
a body;
a light source portion including a light source and a substrate and fixed to the body, the substrate having a first surface to which the light source is fixed and a second surface on which electronic elements are disposed; and
a catalyst portion fixed to the body to face the light source and producing a photocatalytic reaction by light emitted from the light source to generate a superoxide radical;
wherein the substrate includes a connector formed at one side of the second surface of the substrate and fixed,
wherein the connector is electrically connected to the substrate,
wherein the substrate is fixed to the body,
wherein the body includes an upper body and a lower body coupled to each other,
in the upper body, a space is formed in a portion where the connector is positioned so that the connector is supported by the upper body, and
the light source portion and the catalyst portion are positioned between the upper body and the lower body.

2. The photocatalytic device of claim 1 , wherein the body includes a sealing portion protruding from a surface of the body facing the light source portion toward the light source portion.

3. The photocatalytic device of claim 2 , wherein the sealing portion protrudes along an outer edge of the substrate.

4. The photocatalytic device of claim 2 , wherein an internal heat dissipation member is formed on the first surface of the substrate.

5. The photocatalytic device of claim 4 , wherein the internal heat dissipation member is formed to enclose the surface of the substrate except for the sealing portion and a portion where the light source is formed.

6. The photocatalytic device of claim 5 , wherein the internal heat dissipation member is formed to be inclined outward from a central portion where the light source is positioned.

7. The photocatalytic device of claim 2 , wherein an external heat dissipation member is formed on an outer surface of one side of the body.

8. The photocatalytic device of claim 1 , wherein the body includes a horizontal direction fixing member protruding from a surface of the body facing the catalyst portion toward the catalyst portion and contacts a side surface of an end portion of the catalyst portion to fix the catalyst portion.

9. The photocatalytic device of claim 8 , wherein the catalyst portion is formed to have a polygonal shape, and the horizontal direction fixing member is positioned at a vertex portion of the catalyst portion and being in contact with at least two side surfaces of the end portion of the catalyst portion to fix the catalyst portion.

10. The photocatalytic device of claim 8 , wherein the body further includes a vertical direction fixing member protruding inward from a middle portion of the horizontal direction fixing member and being in contact with a surface of the catalyst portion to fix the catalyst portion.

11. A vehicle air conditioner comprising:
an air conditioning case in which a space where introduced air is transferred is formed and a vent for discharging the air is formed;
an evaporator provided in the air conditioning case; a heater core provided at a rear end of the air conditioning case in a direction in which the air flows; and
the photocatalytic device of claim 1 provided in the air conditioning case.

12. The vehicle air conditioner of claim 11 , wherein the catalyst portion is provided so that a surface opposite to a surface facing the light source faces an inside of the air conditioning case.

13. The vehicle air conditioner of claim 11 , wherein the photocatalytic device is provided at a front end or a rear end of the evaporator.

14. The vehicle air conditioner of claim 11 , wherein a predetermined region of the air conditioning case is hollow, a mounting hole closed by the photocatalytic device is formed in the air conditioning case, and the photocatalytic device is fixed in a manner in which a coupling member formed on the body is coupled to an outer surface of the air conditioning case.

15. A vehicle air conditioner comprising:
an air conditioning case in which a space where introduced air is transferred is formed and a vent for discharging the air is formed;
an evaporator provided in the air conditioning case; a heater core provided at a rear end of the air conditioning case in a direction in which the air flows; and
the photocatalytic device of claim 1 provided in the air conditioning case.

16. A vehicle air conditioner comprising:
an air conditioning case in which a space where introduced air is transferred is formed and a vent for discharging the air is formed;
an evaporator provided in the air conditioning case; a heater core provided at a rear end of the air conditioning case in a direction in which the air flows; and
the photocatalytic device of claim 2 provided in the air conditioning case.

17. A vehicle air conditioner comprising:
an air conditioning case in which a space where introduced air is transferred is formed and a vent for discharging the air is formed;
an evaporator provided in the air conditioning case; a heater core provided at a rear end of the air conditioning case in a direction in which the air flows; and
the photocatalytic device of claim 3 provided in the air conditioning case.

18. A photocatalytic device comprising:
A body;
A light source portion including a light source and a substrate having a first surface and a second surface, and fixed to the body, wherein the light source is fixed to the first surface and electronic elements are disposed on the second surface; and
A catalyst portion fixed to the body to face the light source and producing a photocatalytic reaction by light emitted from the light source to generate a superoxide radical;
