Abstract

A hygiene management device for an entrance hall is designed to emit far-UV light from upper and lower sides toward a person by reflecting the far-UV light emitted from the upper side to the person's lower body by a reflector located at the lower side, and reflecting the far-UV light emitted from the lower side to the person's upper body by a reflector located at the upper side. Accordingly, a sterilization effect on the person is improved.

First claim

What is claimed is:

1. A hygiene management device, comprising:
a top plate defining an upper side of the hygiene management device, the top plate including a first Ultra-Violet (UV) emission part configured to emit far-UV light downward toward an upper body of a person; and
a footrest defining a bottom of the hygiene management device, facing the top plate, the footrest including a second UV emission part configured to emit far-UV light upward toward a lower body of the person,
wherein the top plate includes a first concave part, the first concave part having a circumferential surface that is enlarged downward in a center portion of a lower surface of the top plate,
wherein the first UV emission part is located in a first emission area of the first concave part,
wherein the footrest includes a second concave part, the second concave part having a circumferential surface that is enlarged upward in a center portion of an upper surface of the footrest,
wherein the second UV emission part is located in a second emission area of the second concave part,
wherein a first reflector configured to reflect the far-UV light emitted from the second UV emission part toward the upper body of the person is provided along a circumference of the first concave part, and
wherein a second reflector configured to reflect the far-UV light emitted from the first UV emission part toward the lower body of the person is provided along a circumference of the second concave part.

2. The hygiene management device of claim 1 , wherein the first UV emission part is provided on the lower surface of the top plate.

3. The hygiene management device of claim 2 , wherein the lower surface of the top plate includes the first reflector surrounding the first UV emission part, the first reflector being inclined relative to the first UV emission part.

4. The hygiene management device of claim 3 , wherein the first UV emission part includes:
a mounting plate;
a substrate mounted to the mounting plate; and
a UV light source disposed on the substrate configured to emit far-UV light.

5. The hygiene management device of claim 3 , wherein the footrest includes the second reflector disposed on the upper surface of the footrest, the second reflector being inclined relative to the second UV emission part.

6. A hygiene management device, comprising:
a top plate defining an upper side of the hygiene management device, the top plate including a first Ultra-Violet (UV) emission part configured to emit far-UV light downward toward an upper body of a person; and
a footrest defining a bottom of the hygiene management device, facing the top plate, the footrest including a second UV emission part configured to emit far-UV light upward toward a lower body of the person,
wherein the footrest further includes a plurality of support bars provided on an upper surface of the footrest, the plurality of support bars being spaced apart from each other,
wherein the second UV emission part is located within at least one gap between adjacent support bars among the plurality of support bars, and
wherein the second UV emission part includes:
a substrate:
a UV light source disposed on the substrate; and
a light guide plate disposed on the UV light source and between adjacent support bars among the plurality of support bars.

7. The hygiene management device of claim 6 , further comprising an air management module including:
an introduction duct; and
a filter configured to filter air,
wherein the footrest further includes a plurality of air introduction flow paths formed between each of the support bars and configured to introduce air through the footrest into the introduction duct of the air management module.

8. The hygiene management device of claim 1 , further comprising a detector configured to detect the person within the hygiene management device, the detector being provided in at least one of the top plate and the footrest,
wherein each of the first UV emission part and the second UV emission part is configured to:
operate in response to the person being detected by the detector, and
turn off in response to a person not being detected by the detector.

9. The hygiene management device of claim 8 , wherein the top plate includes a discharge hole and is configured to discharge air through the discharge hole towards the person.

10. The hygiene management device of claim 1 , further comprising:
an air management module including:
an introduction duct; and
a filter configured to filter air that is received from the footrest;

a fan assembly connected to the footrest, the fan assembly being configured to receive air from the footrest and generate air flow; and
a duct unit configured to guide air to the top plate.

11. The hygiene management device of claim 10 ,
wherein the top plate further includes a discharge hole that is formed in at least one portion of sides of a perimeter of the first UV emission part.

12. A hygiene management device, comprising:
a top plate positioned an upper side of the hygiene management device, the top plate including:
a first concave part at a lower surface of the top plate and having a concave shape;
a first Ultra-Violet (UV) emission part provided in the first concave part and configured to emit far-UV light downward toward an upper body of a person; and
a first reflector configured to reflect the far-UV light; and

a footrest located on a bottom of the hygiene management device, facing the top plate, the footrest including:
a second concave part provided on an upper surface of the footrest and having a concave shape;
a second UV emission part provided in the second concave part and configured to emit far-UV light upward toward a lower body of the person; and
a second reflector configured to reflect the far UV light,

wherein the footrest further includes a plurality of support bars provided on the upper surface of the footrest, the plurality of support bars being spaced apart from each other, and
wherein the second UV emission part includes:
a substrate;
a UV light source disposed on the substrate; and
a light guide plate disposed on the UV light source and between adjacent support bars among the plurality of support bars.

13. The hygiene management device of claim 12 , wherein the first reflector is positioned along a circumference of the first concave part, and
wherein the second reflector is positioned along a circumference of the second concave part.

14. The hygiene management device of claim 12 , further comprising:
an air management module including:
an introduction duct; and
a filter configured to filter air that is received from the footrest;

a fan assembly connected to the footrest, the fan assembly being configured to receive air from the footrest and generate air flow; and
a duct unit configured to guide air to the top plate.

15. The hygiene management device of claim 14 , wherein the top plate further includes:
a discharge hole that is configured to discharge air towards the person; and
at least one discharge rib disposed between the first UV emission part and a rear surface of the top plate, the at least one discharge rib being configured to guide air from the duct unit to the discharge hole.

16. The hygiene management device of claim 12 , further comprising an air management module including:
