Patent Application
20220186959
The present application claims the priority benefit of Korean Patent Application No. 10-2020-0174512 filed on Dec. 14, 2020 in the Republic of Korea and 10-2021-0015906 filed on Feb. 4, 2021, in the Republic of Korea, which are hereby incorporated by reference in their entirety for all purposes as if fully set forth herein.
The present disclosure relates to a hygiene management device for an entrance hall and a control method of the same.
Generally, in order to enter an indoor space from the outside, a visitor is required to go through an entrance hall which separates the outside from the indoor space. For example, in the case of a house, a vestibule as an entrance hall is provided, and thus to enter the house, a person is required to go through the vestibule.
Recently, air quality outside is getting worse due to yellow dust or fine dust. In this situation, when yellow dust or fine dust enters an indoor space from the outside, the indoor space may be contaminated.
In a dense environment (i.e., a small indoor space), such as an apartment, removing contaminants outside an entrance door may cause the contaminants to be transferred to surrounding people. Accordingly, before a visitor enters an indoor space, it is necessary to remove contaminants attached to the visitor in an entrance hall such as a vestibule.
Technologies for preventing contaminants from being transferred to the indoor space are disclosed.
An air shower for a vestibule of a house is disclosed in (Patent Document 1) Korean Patent Application Publication No. 10-2009-0040630. In the related art disclosed in (Patent Document 1), air is showered on a visitor to remove contaminants, such as dust, on the clothing of the visitor.
However, the air applied to the visitor flows downward from the upper portion, so the air is applied mainly to the visitor's head and to the upper portion of the visitor's upper body and thus contaminants on the visitor's lower body and shoes are not properly removed. Furthermore, in the vestibule, an air introduction hole into, which air is introduced, is located at the side surface of a vestibule space, so contaminants such as dust remain on the bottom of the vestibule.
An air shower system for a vestibule is disclosed in (Patent Document 2) Korean Patent Application Publication No. 10-2020-0117286. In the air shower system disclosed in (Patent Document 2), in addition to the air shower, a photocatalytic lamp is installed on a ceiling to simultaneously remove contaminants, such as dust, and harmful substances, such as viruses, on the clothing of a visitor.
However, even the related art disclosed in (Patent Document 2), has the problems that contaminants, such as dust, remain on the bottom of a vestibule, and contaminants on a visitor's lower body and shoes are not properly removed due to the emission of light by the photocatalytic lamp from the ceiling.
A lighting-integrated air cleaning system for entrance space and a control method of the same are disclosed in (Patent Document 3) Korean Patent Application Publication No. 10-2020-0046715. In the related art disclosed in (Patent Document 3), a lighting fixture and an air cleaning system are integrated with each other such that contaminants are removed from a visitor in an entrance space such as a vestibule.
However, even in the related art disclosed in (Patent Document 3), a structure in which air is simply discharged downward from the upper side is integrated with the light fixture, and an air introduction hole is formed in the side surface of the entrance space, so contaminants in the entrance space are not properly removed.
An air shower apparatus integrated with a vestibule door is disclosed in (Patent Document 4) Korean Patent Application Publication No. 10-2019-0055303. In the related art disclosed in (Patent Document 4), a shower booth having a shower space thereinside is separately installed, such that a visitor can remove contaminants in the shower booth.
However, the shower booth disclosed in (Patent Document 4) is separately partitioned in space inside a vestibule, and thus a space occupied by an entire device inside the vestibule increases, so the air shower apparatus is not effective. Furthermore, the air shower apparatus has a simple structure in which air is discharged downward from an upper side, so ability with which the air shower apparatus removes contaminants decreases.
In addition in the related arts disclosed in Patent Documents 1 to 4 described above, in a process in which a visitor opens and closes an entrance door, outdoor contaminants are introduced through the entrance door into a vestibule and the internal space of the vestibule is contaminated.

The exemplary embodiment of a hygiene management device for an entrance hall of the present disclosure and the control method of the same will be described in detail with reference to the accompanying drawings.
The hygiene management device 1000 according to the embodiment of the present disclosure may be installed inside the space 12 (e.g., entrance space 12) of the entrance hall 10 for access to a specific indoor space. When the hygiene management device is installed in a residential space 12, the hygiene management device may be installed in a vestibule. When the hygiene management device is installed in an office space 12, the hygiene management device may be installed in space which is separately partitioned in the entrance hall of the associated office space.
An entrance door 14 for going out to or coming in from the outside may be provided at a first side surface of the entrance hall 10, and an inside door 16 for entering and exiting the indoor space may be provided at a second side surface of the entrance hall 10 opposite to the first side surface of the entrance hall 10.
A footrest 100 may be installed on the bottom of the entrance hall 10 having space 12 defined therein. The footrest 100 may have a predetermined area (i.e., a predetermined size and shape) such that a visitor can stand on the footrest 100 and may function to support the visitor.
As illustrated in the drawing, the footrest 100 may be configured as a rectangular plate shape having space defined therein. However, according to the shape of the entrance space 12, the shape of the footrest 100 may be configured to have various plate shapes or any type of shape.
A plurality of introduction holes may be formed in the upper surface of the footrest 100 such that air in the space 12 of the entrance hall 10 is introduced into the footrest 100, and due to the operation of a fan assembly 300, which is described below, the air in the space 12 of the entrance hall 10 may be introduced into the footrest 100.
The air introduced into the internal space of the footrest 100 through such introduction holes may be transferred through a predetermined flow path to an air management module 200. The air management module 200 may remove foreign matter contained in the air transferred thereto through the predetermined flow path and may function to manage the humidity and temperature of the air.
The air management module 200 may include a plurality of filters 221, 223, and 225. These filters 221, 223, and 225 may be disposed in an air flow path formed in the air management module such that air supplied to the air management module 200 passes through the filters 221, 223, and 225.
Each of the filters 221, 223, and 225 may have a specific function. For example, a first filter 221 may have the function of removing moisture. A second filter 223 may have the function of removing contaminants and dust (e.g., fine dust). A third filter 225 may have an antibacterial function. Alternatively, filters having other functions may be included in the air management module 200.
In order to preset the temperature of air passing through the air management module 200, a heat exchanger 240 may be installed. The heat exchanger 240 may exchange heat with air passing through the filters 221, 223, and 225. The heat exchanger 240 may be installed in a heat exchanger casing 242.
Air may flow through the heat exchanger casing 242 in a front-to-rear direction, with the front direction facing towards the footrest 100 and the rear direction facing away from the footrest 100. The outlet of the heat exchanger casing 242 may communicate with the fan assembly 300 to be described below. There may be components of a heat exchange cycle for heat exchange. Reference numeral 244 denotes a compressor.
The fan assembly 300 may be mounted to the rear surface of the air management module 200, that is, the outlet of the air management module 200 through which air flows out. The fan assembly 300 may supply an air blowing force such that air flows in the hygiene management device 1000. Due to such an air blowing force, an air discharger 500 to be described below may discharge air to the outside.
A fan housing 310 may constitute the exterior of the fan assembly 300. A housing internal space 314 may be defined in the fan housing 310, and the housing internal space 314 may be configured such that air introduced to the fan housing 310 from a position in front of the fan housing 310 is discharged from the fan housing 310 through an outer surface thereof.
A fan 316 may be installed in the fan housing 310. The fan 316 may be driven by a fan motor to allow air to be introduced to the fan housing 310 through an inlet of the fan housing 310 and to allow the air to be discharged through the outlet of the fan housing 310.
A function module 350 may be installed on a position corresponding to the upper side of the air management module 200 (i.e., positioned above the air management module 200). There may be a clothing management device as an example of the function module 350. When clothes are placed inside the clothing management device, the clothing management device can remove dust from the clothes or sterilize the clothes. In addition, the clothing management device may function to unwrinkle clothing, such as by steaming. Further, any type of item may be inserted into the function module 350, such as shoes, glasses, an umbrella or the like.
As other examples of the function module 350, there may be various devices such as a shoe management device, an umbrella management device, a shoe storage device, and an umbrella storage device. For reference, each of these function modules 350 may not be configured as an independent function module, but some of the function modules may be combined with each other.
A control panel 352 may be mounted to the front surface part of the function module 350 (i.e., a surface disposed between the footrest 100 and the air discharger 500) so as to preset and control various operations and functions of the hygiene management device 1000 of the present disclosure. Such a control panel 352 may preset and control the various operations and functions of the function module 350.
The control panel 352 may be a device in which an input device and a display device (a display, such as a touch screen, and OLED screen and the like) are integrated with each other. The input device may be embodied as a touch pad or a touch screen.
A duct 400 may function to move an air flow generated in the fan assembly 300 to the relatively upper portion of the entrance hall 10. The duct 400 may include a first duct 410 and a second duct 420.
The first duct 410 may extend along the side wall of the entrance hall 10, may extend vertically and may define an outer side surface of the hygiene management device 1000. A first inlet 412 of the first duct 410 may be connected to the outlet of the fan housing 310 of the fan assembly 300, and thus air may be transferred through the outlet of the fan housing 310 to the first inlet 412 of the first duct 410.
The first duct 410 may have a branch flow path through which air can be supplied to the function module 350. There may be a separate damper inside each of the branch flow path and the first duct 410 to control the flow of air therein.
The second duct 420 may be located on the upper portion of the entrance hall 10. The second duct 420 may allow air passing through the first duct 410 to flow therein such that the air can be supplied to the air discharger 500 to be described below. The second duct 420 may have a first outlet 422 and a second outlet 424.
The first outlet 422 may be located in a relatively upstream portion of the second duct 420 relative to the flowing direction of air inside the second duct 420, and the second outlet 424 may be located in a relatively downstream portion of the second duct 420 compared to the first outlet 422. As illustrated in
The air discharger 500 may be connected to the second duct 420 of the upper portion of the entrance hall 10. The air discharger 500 may discharge air transferred through the duct 400 into the space 12 of the entrance hall 10.
The air discharger 500 may discharge air transferred through each of the first outlet 422 and the second outlet 424 of the second duct 420 into the space 12. The air discharger 500 may preset and change the amount (i.e., volume), speed, and direction of the transferred air.
Discharge holes through which air is discharged may be formed in the air discharger 500. In the embodiment, the discharge holes may be formed in positions, respectively, corresponding to the first outlet 422 and the second outlet 424 of the second duct 420. The discharge holes may be open to the lower surface of the air discharger 500.
A corrugated pipe 556 may be installed on a portion on which the second duct 420 and the air discharger 500 are connected to each other to prevent air from leaking even when the air discharger 500 moves.
The corrugated pipe 556 may be flexible, and thus although the air discharger 500 moves relative to the duct 400, a connection state between the second duct 420 and the air discharger 500 may be maintained. The corrugated pipe 556 may connect the second duct 420 with the air discharger 500 in each of the first outlet 422 and the second outlet 424 of the second duct 420. That is, the corrugated pipe 556 may be provided in plurality.
The air discharger 500 may be provided with a lift assembly 520. The lift assembly 520 may include a first lift 521 and a second lift 521′. The lift assembly 520 may be driven by a controller 900, which is described below.
The first and second lifts 521 and 521′ are intended to tilt the air discharger 500 by moving up and down the opposite edges of the air discharger 500.
The first lift 521 and the second lift 521′ may be installed on the opposite edges of the air discharger 500, respectively, and a specific portion of the air discharger 500 may be moved down by these lifts 521 and 521′ so as to tilt the air discharger 500.
Accordingly, a direction (e.g., an angle) to which the lower surface of the air discharger 500 is directed may be adjusted to adjust the discharge direction of air. A driving force for operating the first and second lifts 521 and 521′ may be supplied by at least one lift motor 525. Specifically, there may be two lift motors 525, as shown in
A portion of each of parts of the first and second lifts 521 and 521′ may be mounted to the second duct 420 or the upper portion of the entrance space 12, and the remaining portion thereof may be mounted to the air discharger 500. That is, a first portion or a first end of each of parts of the first and second lifts 521 and 521′ may be mounted to the second duct 420 or the upper portion of the entrance space 12, and a second portion or a second end thereof may be mounted to the air discharger 500. Due to a specific part of the air discharger 500 moved up and down by the lifts 521 and 521′, a direction to which the lower surface of the air discharger 500 is directed may be adjusted.
The first and second lifts 521 and 521′ may be replaced by other components which perform the same functions, as known in the art. In the hygiene management device of the present disclosure, any components which can tilt the air discharger 500 in a specific direction may be applied.
Multiple vanes 560 and 560′ (e.g., a plurality of vanes 560, and a plurality of vanes 560′) may be installed respectively between the first outlet 422 of the duct 400 and a first side discharge hole of the air discharger 500 and between the second outlet 424 of the duct 400 and a second side discharge hole of the air discharger 500.
A vane rotation center member 558 may be mounted to each of the first outlet 422 and the second outlet 424 of the second duct 420. Multiple vanes 560 or 560′ may be mounted to each vane rotation center member 558 such that the multiple vanes can rotate at predetermined angles. That is, the vane rotation center member 558 controls the rotation of the plurality of vanes 560, 560′ of the respective side of the air discharger 500.
Each of the vanes 560 or 560′ (i.e., plurality of vanes may preset the direction of air to be discharged through the discharge holes of the air discharger 500. The vane 560 or 560′ may include multiple vanes disposed at predetermined intervals.
The vane 560 or 560′ may function to preset the direction of air to be discharged through the discharge holes. As illustrated in
At least a portion of the upper flow part of the vane 560 or 560′ may be located inside the second duct 420. The lower flow part of the vane 560 or 560′ may be mainly located inside the air discharger 500.
The vane 560 or 560′ may have more portions located in the second duct 420 gradually in an air flow direction in the second duct 420. That is, the vane 560 or 560′ may be located at the position of height increasing gradually in the air flow direction in the second duct 420. Additionally, the vane 560 located in the second outlet 424 may be located at a position higher than the vane 560′ located in the first outlet 422.
Such configuration can be seen even in
As for the length of the vane 560 or 560′, the vane 560′ located at the first outlet 422 may be longer than the vane 560 located at the second outlet 424. This is intended to allow air to flow through the discharge holes without air being wasted gradually toward the end of the second duct 420.
The vane 560 or 560′ may guide air to the lower portion of the air discharger 500. According to the rotated state of the vane 560 or 560′ relative to the vane rotation center member 558, a direction in which the vane guides air may be changed.
A vane drive member 562 may be provided to control the operation state of each of the vane 560 and 560′. Like the vane rotation center member 558, the vane drive member 562 maybe connected to each of the vanes 560 and 560′.
The vane drive member 562 may be connected relatively rotatably to the vane 560 or 560′ at a position located apart from a portion at which the vane rotation center member 558 is connected to the vane 560 or 560′ and toward the discharge holes. One vane drive member 562 may be used for each of the opposite sides of the vane 560 or 560′. That is, one vane drive member 562 may be used for both of the vanes 560, 560′. Alternatively, only one vane drive member 562 may be used for the vane 560 or 560′. That is, each vane 560 or 560′ may have its own vane drive member 562.
Vane motors 570 may be provided to drive the vanes 560 and 560′, respectively. A drive link 574 may be connected to each of the vane motors 570. The drive link 574 may be driven by the operation of the vane motor 570. Further, each drive link 574 may be connected to the vane motor 570 via a drive part 580. That is, each drive part 580 may extend between a respective drive link 574 and the respective vane drive member 562.
The vane drive member 562 may be connected to the drive link 574 and may be driven according to the operation of the drive link 574.
Meanwhile, the hygiene management device 1000 may include a first detector 354 and a second detector 356. A first detector 354 may detect the opening/closing of the entrance door 14, and the second detector 356 may detect whether a user is present at a preset position in the space 12 of the entrance hall 10. The second detector 356 may preferably detect whether the user is present on the footrest 100.
The first detector 354 may be mounted to the entrance door 14, and for example, may be embodied as a reed switch or a push-pull switch.
The second detector 356 may be mounted to the front surface part of the function module 350. However, the installation location of the second detector 356 may be any location in which a user on the footrest 100 can be detected. For example, the second detector 356 may be embodied as an infrared sensor, an ultrasonic sensor, or a laser distance sensor.
Alternatively, the second detector 356 may be mounted to the footrest 100 and may detect whether a user stands on the footrest 100. Accordingly, the second detector 356 may be embodied as a weight sensor or a piezoelectric sensor.
The first and second detectors 354 and 356 may transmit results respectively detected thereby to the controller 900, which is described below.
Referring to
In a state in which the hygiene management device 1000 of the present disclosure is installed in the space 12 of the entrance hall 10, as shown in
In the standby state, when the entrance door 14 is opened, the first detector 354 may detect the opening of the entrance door 14 at S103. The detected result may be transmitted to the controller 900.
Accordingly, the controller 900 may drive the lift assembly 520 and may tilt the air discharger 500 such that the lower surface part of the air discharger 500 is directed toward the entrance door 14 at S105. That is, the direction of air discharged by the air discharger 500 may be directed toward the entrance door 14.
In addition, the controller 900 may drive the fan assembly 300 such that air is discharged by the air discharger 500 at S107.
This is intended for the air discharger 500 to discharge air toward the entrance door 14 such that external air is prevented from being introduced into the entrance space 12 through the opened entrance door 14. In this case, in the state in which the air discharger 500 is tilted, the fan assembly 300 may be driven to discharge air with a relatively higher wind pressure.
Accordingly, the air discharger 500 may discharge air slantingly toward the entrance door 14. When the air discharger 500 operates in the opposite direction, the air discharger 500 may be restored to a present initial position from the tilted state of the air discharger 500.
Here, the tilting of the air discharger 500 at S105 and the discharging of air at S107 may be performed simultaneously or within a preset time difference. Alternatively, in another embodiment, the discharging of air may be performed before the tilting.
Later, when the entrance door 14 is closed, the first detector 354 may detect the closing of the entrance door 14 at S109. The detected result may be transmitted to the controller 900.
Accordingly, the controller 900 may drive the lift assembly 520 such that the air discharger 500 tilted toward the entrance door 14 is restored to an initial position at S111. At the initial position, the direction of air discharged by the air discharger 500 may be directed toward the center of the space 12 of the entrance hall 10.
When the air discharger 500 is tilted to the initial position, whether to stop the air discharge may be determined according to whether there is a user in the space 12 of the entrance hall 10.

The hygiene management device 1000 may maintain a standby state at S201, and when a user stands on the footrest 100, the second detector 356 may detect the user on the footrest 100 at S203. The detected result may be transmitted to the controller 900.
Accordingly, the controller 900 may drive the fan assembly 300 such that the air discharger 500 discharges air toward the user at S205. This is intended to remove contaminants attached to the user's body and clothes by the air discharge.
The air discharge may be performed for a preset period of time, and when the preset period of time elapses at S207, the controller 900 may stop the fan assembly 300 and the air discharge may stop at S209.
However, before the preset period of time elapses, when the user descends from the footrest 100 (i.e., the user steps off the footrest 100), the second detector 356 may detect this at S211, and the controller 900 may stop the fan assembly 300 such that the air discharge stops at S209.
As described above, when the fan 316 operates due to the operation of the fan assembly 300, an air flow may be generated. Hereinafter, the introduction and discharging of air according to the air flow will be described.
When the fan assembly 300 is operated by the controller 900, the fan 316 may rotate. Due to the rotation of the fan 316, air may be introduced into the footrest 100 through the multiple introduction holes formed in the footrest 100. In
The introduced air may be introduced through the first, second, and third filters 221, 223, and 225 of the air management module 200 into the fan assembly 300. The air introduced into the fan assembly 300 may flow due to the rotation of the fan 316, and may be introduced into the duct 400.
The air transferred to the first duct 410 of the duct 400 may flow to the second duct 420 and may be transferred sequentially to the first outlet 422 and the second outlet 424 of the second duct 420. The vanes 560 and 560′ may be located at the first outlet 422 and the second outlet 424, respectively, and thus the flowing air may be introduced into to the first outlet 422 and the second outlet 424 by being guided by the vanes 560 and 560′, respectively.
In addition, the multiple vanes may be disposed at each of the first outlet 422 and the second outlet 424 such that the vanes have a predetermined height difference therebetween and are spaced apart at predetermined intervals from each other, so air may be spread relatively evenly in the first outlet 422 and the second outlet 424 to flow.
For the operation of the vane 560, the drive link 574 may be reciprocated rectilinearly by the vane motor 570. Due to the rectilinear reciprocation of the drive link 574, the vane drive member 562 may move and thus the vane 560 may rotate at a predetermined angle relative to the vane rotation center member 558 (e.g., via the drive part 580). Due to such rotation of the vane 560, air discharge direction may be changed.

When the entrance door 14 is opened such that a user goes into the entrance space 12 from the outside while the hygiene management device 1000 maintains a standby state at S301, the first detector 354 may detect the opening of the entrance door 14 at S303. The detected result may be transmitted to the controller 900.
Accordingly, the controller 900 may drive the lift assembly 520 and may tilt the air discharger 500 such that the lower surface of the air discharger 500 is directed toward the entrance door 14 at S305. Additionally, the controller 900 may enable the air discharger 500 tilted by driving the fan assembly 300 to discharge air toward the entrance door at S307.
Next, when the entrance door 14 is closed after the user comes into the space 12 of the entrance hall 10, the first detector 354 may detect the closing of the entrance door 14 at S309. The detected result may be transmitted to the controller 900.
Accordingly, the controller 900 may stop the fan assembly 300 such that air discharge stops at S311. Additionally, the controller 900 may drive the lift assembly 520 such that the air discharger 500 tilted toward the entrance door 14 is restored to an initial position at S313.
Later, when a user is located on the footrest 100, the second detector 356 may detect this at S315. The result detected by the second detector 356 may be transmitted to the controller 900 (e.g., as shown in
Accordingly, the controller 900 may drive the fan assembly 300 such that the air discharger 500 discharges air toward a user at S317. In this case, due to the operation of the fan assembly 300, the footrest 100 may introduce air in the entrance space 12 thereto through the multiple introduction holes.
The air discharge may be performed for a preset period of time, and when the preset period of time elapses at S319, the controller 900 may stop the fan assembly 300 and stop the air discharge at S321.
However, before the preset period of time elapses, when the user descends from the footrest 100 (i.e., the user steps off of the footrest 100), the second detector 356 may detect this at S323, and the controller 900 may stop the operation of the fan assembly 300 to stop air discharge at S321.

In a state in which the hygiene management device 1000 is in a standby state at S401, when a user coming out through the inside door 16 stands on the footrest 100, the second detector 356 may detect the user on the footrest 100 at S403 and may transmit the detected result to the controller 900.
Accordingly, the controller 900 may drive the fan assembly 300 such that the air discharger 500 discharges air toward the user at S405.
The air discharge may be performed for a preset period of time, and when the preset period of time elapses at S407, the controller 900 may stop the fan assembly 300 and may stop the air discharge at S409.
When the entrance door 14 is opened such that the user goes out to the outside from the entrance space, the first detector 354 may detect the opening of the entrance door 14 at S411 and may transmit the detected result to the controller 900.
Accordingly, the controller 900 may drive the lift assembly 520 and tilt the air discharger 500 toward the entrance door 14 at S413. Additionally, the controller 900 may drive the fan assembly 300 such that the air discharger 500 discharges air toward the entrance door 14 at S415.
The tilting of the air discharger 500 at S413 and the discharging of air at S415 may be performed simultaneously or within a preset time difference.
Later, when the entrance door 14 is closed after the user goes out to the outside, the first detector 354 may detect the closing of the entrance door 14 at S417. The detected result may be transmitted to the controller 900.
Accordingly, the controller 900 may stop the operation of the fan assembly 300 such that the air discharger 500 stops the air discharge at S419. Additionally, the controller 900 may drive the lift assembly 520 such that the air discharger 500 tilted toward the entrance door 14 is tilted to an initial position to be restored thereto at S421, as shown in
