Abstract

A hygiene management device for an entrance hall includes a fan assembly, a duct and an air discharger that discharges air toward a person at positions around the person in consideration of a person's height or such that an air discharge angle is adjusted upward/downward in consideration of a person's face position or a person's height.

First claim

What is claimed is:

1. A hygiene management device, comprising:
a fan assembly configured to generate an air flow;
a duct connected to the fan assembly and configured to guide a flow of the air; and
an air discharger connected to the duct and configured to discharge the air guided from the duct to a person, the air discharger including:
a top plate located at an upper side of an entrance space;
a footrest located at a bottom side of the entrance space and facing the top plate; and
a plurality of pillar frames connecting the top plate with the footrest, each pillar frame having a discharge nozzle part which discharges air to the person,
wherein each pillar frame is positioned between the top plate and the footrest and is rotatable, and
wherein each pillar frame is disposed on an edge portion of the footrest.

2. The hygiene management device of claim 1 , wherein the plurality of pillar frames are mounted to at least two corners of the top plate and to corresponding corners of the footrest.

3. The hygiene management device of claim 1 , further comprising a plurality of pillar rotating parts provided on an upper surface of the top plate to enable rotation of the plurality of pillar frames.

4. The hygiene management device of claim 3 , wherein each pillar rotating part comprises a rotary motor configured to rotate to adjust a rotation angle of each pillar frame.

5. The hygiene management device of claim 1 , further comprising:
an upper roller provided on an upper surface of each pillar frame;
an upper guide groove formed in the top plate and receiving the upper roller to guide a movement of the upper roller;
a lower roller provided on a lower surface of each pillar frame; and
a lower guide groove formed in the footrest and receiving the lower roller to guide a movement of the lower roller.

6. The hygiene management device of claim 1 , wherein the discharge nozzle part includes a plurality of discharge nozzle parts, the plurality of discharge nozzle parts being located on each of the plurality of pillar frames to be spaced vertically apart from each other.

7. The hygiene management device of claim 1 , wherein each of the discharge nozzle part is configured to selectively receive air from the duct.

8. The hygiene management device of claim 1 , wherein each of the plurality of pillar frames includes a detector configured to detect a person's height or face position.

9. The hygiene management device of claim 8 , wherein the detector is located at the discharge nozzle part.

10. The hygiene management device of claim 1 , wherein the discharge nozzle part is configured to have an adjustable inclination angle in an upward/downward direction to adjust an upward/downward discharge direction of air.

11. The hygiene management device of claim 10 , wherein the discharge nozzle part includes a rotation shaft mounted rotatably to the discharge nozzle part such that the discharge nozzle part is configured to incline upward/downward relative to each of the plurality of pillar frames, and
wherein each of the plurality of pillar frames includes a nozzle angle adjustment part that is configured to cause a rotation of the rotation shaft.

12. The hygiene management device of claim 11 , wherein the nozzle angle adjustment part includes an angle adjustment motor connected to the rotation shaft directly or by a power transmission member such that power is transmitted between the angle adjustment motor and the rotation shaft.

13. The hygiene management device of claim 1 , wherein the duct includes:
a first duct positioned along a side of the footrest; and
a second duct extending from the first duct and located above the top plate, and
wherein the second duct and each of the plurality of pillar frames are connected to each other by a guide tube, the guide tube being configured to transmit air between the second duct and each of the plurality of pillar frames.

14. The hygiene management device of claim 13 , wherein the discharge nozzle part includes:
a discharge casing having a discharge hole formed therein such that air is discharged through the discharge hole; and
an air transfer duct positioned along an inside of each of the plurality of pillar frames, the air transfer duct being configured to receive air from the guide tube to transfer the air to the discharge casing.

15. The hygiene management device of claim 14 , wherein the guide tube includes a flow path opening/closing valve configured to open/close an associated flow path with the air transfer duct.

16. The hygiene management device of claim 1 , further comprising an air management module connected to an air inlet of the fan assembly and configured to remove foreign matter or contaminants from air before the air enters the fan assembly,
wherein the footrest includes an introduction flow path that is configured to guide air flow to the air management module.

17. A hygiene management device, comprising:
an air discharger including:
a top plate located at an upper side of an entrance space;
a footrest located at a bottom side of the entrance space opposite to the upper side; and
a plurality of pillar frames connecting the top plate with the footrest and extending between the top plate and the footrest, each of the plurality of pillar frames having at least one adjustable discharge nozzle part configured to discharge air at varying angles to the entrance space,
wherein each pillar frame is positioned between the top plate and the footrest and is rotatable, and
wherein each pillar frame is disposed on an edge portion of the footrest.

18. The hygiene management device of claim 17 , further including:
a plurality of pillar rotating parts provided on an upper surface of the top plate so as to enable rotation of the plurality of pillar frames; and
a drive member,
wherein each of the plurality of pillar rotating parts includes a plurality of rollers and a plurality of guide grooves receiving the plurality of rollers, the plurality of rollers being configured to move within the plurality of guide grooves, and
wherein the drive member is configured to apply a driving force to the plurality of rollers to cause the plurality of rollers to move within the plurality of guide grooves to move the plurality of pillar frames.

19. The hygiene management device of claim 17 , further comprising a detector configured to determine a location of a person disposed in the hygiene management device,
wherein each of the plurality of pillar frames are configured to rotate such that air is blown by each pillar frame to the location of the person determined by the detector.

20. The hygiene management device of claim 19 , wherein the at least one adjustable discharge nozzle part is configured to only discharge air to a maximum height of the person.
