signal-processed video, audio, or data signals. The storage unit
370 may store various platforms. The storage unit 370 may include,
for example, at least one storage medium of a flash memory type
storage medium, a hard disk type storage medium, a multimedia card
micro type storage medium, or a card type storage medium (e.g.,
secure digital (SD) or eXtreme Digital (XD) memory, and the like),
random-access memory (RAM) storage medium, or read-only memory
(ROM) storage medium (e.g., electrically erasable and programmable
read only memory (EEPROM) storage medium.
[0063] According to an embodiment, the air volume controller 330
may control a discharger to control an amount of air discharged.
For example, the air volume controller 330 may control the amount
of air discharged through the discharger by adjusting a number of
rotations of the blower fan based on the control signal provided by
the processor 310.
[0064] According to one embodiment, the wind direction controller
340 may control the direction of air discharged by the discharger
by adjusting an angle of at least one of the first vane to the
fourth vane 210, 220, 230, and 240. For example, the wind direction
controller 340 adjusts the rotation angle of the at least one of
the first vane to the fourth vane 210, 220, 230, and 240 based on
the control signal provided by the processor 310 to control the
direction of the discharged air. For example, when the occupant is
detected by a motion sensing sensor 260 described below, the wind
direction controller 340 may adjust the angle of the at least one
of the first vane to the fourth vane 210, 220, 230, and 240 to face
the user (e.g., the occupant) under the control of the processor
310.
[0065] According to one embodiment, the sensor unit 320 may include
a temperature measurement sensor 321 and a motion sensing sensor
260. The temperature measurement sensor 321 includes at least one
temperature measurement sensor to measure a temperature and the
motion sensing sensor 260 includes at least one motion sensing
sensor to detect movement of the object.
[0066] According to an embodiment, the temperature measurement
sensor 321 may include a plurality of temperature measurement
sensors. In addition, the temperature measurement sensor 321 may
detect a temperature of the air discharged by the air conditioner
200, a temperature of the air suctioned into the air conditioner
200, an indoor space temperature, a temperature of a
refrigerant-suctioning pipe, and a temperature of
refrigerant-discharging pipe, and the like, using the temperature
measurement sensors, and may provide the processor 310 with the
detected result. The temperature measurement sensor 321 may include
an infrared camera to measure a temperature.
[0067] According to an embodiment, the motion sensing sensor 260
may detect a user (e.g., an occupant) in an indoor space where the
air conditioner 200 is disposed. The motion sensing sensor 260 may
be disposed on an outer surface of the air conditioner 200 and may
be rotatable. The motion sensing sensor 260 may detect a user's
movement in the indoor space where the air conditioner 200 is
disposed and transmit, to the processor 310, a signal related to
the detection degree. Subsequently, the processor 310 may identify
whether the user is currently drowsing.
[0068] The motion sensing sensor 260 may scan the indoor space by
being rotated under the control of the processor 310 and may detect
the user (e.g., the occupant) in the indoor space. The motion
sensing sensor 260 may detect the user with various methods. For
example, the motion sensing sensor 260 may detect the user with
infrared rays. In addition, the motion sensing sensor 260 may
detect the user using a radiant heat emitted from the user and may
detect the user using a camera. The motion sensing sensor 260 may
include a vision sensor. In addition, the motion sensing sensor 260
may detect the user using various methods for identifying the
user.
[0069] The detection operation of the motion sensing sensor 260 may
be performed every preset detection period (e.g., 10 seconds) and
the motion sensing sensor 260 may provide the processor 310 with
the user (e.g., occupant) detection information.
[0070] According to an embodiment, the processor 310 may obtain an
activity amount of the occupant based on the position of the
occupant detected by the motion sensing sensor 260. In addition,
the processor 310 may include at least one circuit (or a processor)
to control a temperature of the air conditioner 100 using a timer
311 for a preset time period based on the obtained result. The
activity amount is a parameter indicating movement degree of an
occupant and may be understood as a movement distance of the
occupant. Alternatively, the activity amount may be understood as a
parameter proportional to the moving distance of the occupant. The
processor 310 may identify changes in occupant's position based on
the occupant's positions detected every detection time period and
may obtain the activity amount of the occupant based on the change
in the occupant's positions. For example, the processor 310 may
identify the position of the occupant detected by the motion
sensing sensor 260 and obtain the activity amount of the occupant
based on the change in the occupant's position during a reference
period. The processor 310 may identify whether the occupant is
currently drowsing based on the obtained result. The processor 310
may control the at least one sensor of the motion sensing sensor
260 to periodically detect the movement of a user's body part
(e.g., the head). In addition, the processor 310 may identify
whether the user is currently drowsing based on the detection of
the movement of the user's body part (e.g., the head).
[0071] The processor 310 may detect the indoor environment and
operate the air conditioner 200 in a concentration enhancing mode
according to a method described below, or only when an instruction
regarding the concentration enhancing mode is received from the
user, the processor 310 may operate the air conditioner 200 in the
concentration enhancing mode. In addition, the processor 310 may
operate the air conditioner 200 in a mode (e.g., concentration
enhancing mode) selected from various modes (e.g., a concentration
enhancing mode, a sleep mode, a refresh mode, and the like).
[0072] The processor 310 may measure a temperature change rate for
each space based on the temperature change of each space measured
by the temperature measurement sensor unit 321. The processor 310
may measure the temperature change rate in a constant time period
unit, for example, an hour unit. The processor 310 may identify
space information based on the temperature change rate measured by
the temperature measurement sensor unit 321. In this case, the
processor 310 may control the storage unit 370 to store the space
information based on the temperature change rate in advance and
detect space information identical to the identified space
information of the stored space information. In this case, the
space information may include information on an open window, a
closed wall, the living room having a large space, and the
like.
[0073] According to an embodiment, the processor 310 may control
the communicator 350 to receive the signal from the remote control
device 270. The received signal may include information on a total
operation time period during which the air conditioner operates.
The processor 310 may divide the total operation time period into a
plurality of time periods. In addition, the processor 310 may
control at least one of the angle of each vane, the temperature set
on the air conditioner 200, and the volume of air flowing toward
the object in each period of the divided time periods to differ
from at least one of the angle of each vane, the temperature set on
the air conditioner 200, and the volume of air flowing toward the
object in a previous time period of the each time period.
[0074] According to an embodiment, the at least one processor 310
may control the air conditioner 200 to be operated at a first
temperature and control the wind direction controller 340 to
automatically swing the at least one vane during a first time
period among the divided plurality of time periods. According to
one embodiment, the at least one processor 310 may control the wind
direction controller 340 to automatically swing the at least one
vane for a predetermined first sub-time period (e.g., 20 minutes)
among the first time period.
[0075] The at least one processor 310 may control at least one of
an angle of at least one vane 210, 220, 230, and 240, the
temperature, and the air volume of the air conditioner 200 based on
the received signal in the predetermined hour unit. The air
conditioner 200 may further include a sensor unit 320. The sensor
unit 320 includes a motion sensing sensor 260 to detect movement of
an object and a temperature measurement sensor 321 to measure a
temperature of a space where the air conditioner is disposed.
[0076] According to one embodiment, the at least one processor 310
may control the at least one of the angle of each vane of the at
least one vane 210, 220, 230, and 240 adjusted by the wind
direction controller 330, the temperature set on the air
conditioner, the air volume controlled by the air volume controller
330 in the predetermined time period unit. The at least one
processor 310 may adjust the angle of each vane, the temperature,
and the air volume based on the movement of the object.
[0077] According to one embodiment, the at least one processor 310
may control the motion sensing sensor 260 to identify the object's
position based on the received signal. In addition, the at least
one processor 310 may detect the movement of the identified object
and identify whether the object is drowsing based on the detected
movement of the object.
[0078] According to an embodiment, the at least one processor 310
may operate the air conditioner 200 in a first mode after the
predetermined first sub-time period (e.g., 20 minutes). In the
first mode, at least one processor 310 controls the air volume
controller 330 to adjust the air volume to first air volume (e.g.,
high air volume), and the at least one processor 310 controls the
wind direction controller 330 to adjust an angle of the at least
one vane to a first angle for a predetermined second sub-time
period (e.g., 3 seconds), and after the predetermined second
sub-time period, to adjust the angle of the at least one vane to a
second angle that is greater than the first angle for a
predetermined time period (e.g., 5 seconds) for automatically
swinging the at least one vane. In addition, the first mode is a
mode in which at least one processor 310 controls the wind
direction controller 330 to automatically swing the at least one
vane for a predetermined fourth sub-time period (e.g., 7 seconds)
after the predetermined third sub-time period.
[0079] According to an embodiment, the at least one processor 310
may operate the air conditioner in the first mode during the first
time period, and subsequently, operate the air conditioner
sequentially and repeatedly in the second mode and the third mode
during the second time period subsequent to the first time period.
The second mode is a mode in which the air conditioner is operated
by adjusting the first temperature in the first mode to a second
temperature that is higher than the first temperature by a
predetermined temperature (e.g., 1 Celsius degree) and the at least
one processor 310 controls the air volume controller 330 to adjust
the wind volume to second air volume (e.g., low air volume) that is
less than the first air volume (e.g., high air volume). The third

the second mode and the third mode for the second time period. The
at least one processor 310 may operate the air conditioner 200 in
the first mode for a third time period subsequent to the second
time period. According to an embodiment, the at least one processor
310 may repeatedly and sequentially operate the air conditioner 20
in the first mode to the fourth mode during the total operation
time period.
[0081] FIG. 4 is an exemplary view showing an indoor space divided
into a plurality of virtual sub-areas.
[0082] Referring to FIG. 4, the processor 310 may map a position of
an occupant detected by a motion sensing sensor 260 to a virtual
area 400 divided into the sub-areas and detect movement of the
occupant based on a distance between the mapped virtual areas. The
virtual area 400 may include identifiers VA1 to VA24 preset
according to positions thereof and the occupant may be located in
one or two areas. In addition, information on the virtual area 400
and the identifiers thereof may be stored in advance in the storage
unit 370. The processor 310 may identify a position 410 of the
occupant detected by the motion sensing sensor 260 and map the
identified position of the occupant to the virtual area 400. For
example, the processor 310 may map the position of the occupant
detected during the detection period to the virtual area 400 for
each detection time period.
[0083] FIG. 5 is a flowchart showing an example process of
controlling an air conditioner.
[0084] Hereinafter, a process of controlling the air conditioner
according to an embodiment of the present disclosure is described
in detail with reference to FIG. 5.
[0085] According to an embodiment, at least one processor 310 may
determine whether a signal for controlling an operation of the air
conditioner is received (S510). The received signal may include
information on a total operation time period during which the air
conditioner 200 operates. The total operation time period (e.g., 5
hours) may be set by the user. The at least one processor 310 may
control the motion sensing sensor 260 to identify the position of
an object (e.g., a person) based on receiving the signal and
determine whether a body portion (e.g., the head) of the identified
object is periodically is moving. In addition, the at least one
processor 310 may identify that the object (e.g., the person) is
drowsing based on the above determination.
[0086] According to an embodiment, the at least one processor 310

air conditioner in a predetermined time period unit based on the
received signal. (S512). The at least one processor 310 may control
at least one of the angle of the at least one vane 210, 220, 230,
and 240 adjusted by the wind direction controller 340, the

controlled by the air volume controller 330 in the predetermined
time period unit. The at least one processor 310 may adjust the
angle of each of the vanes, the temperature, and the air volume
based on the movement of the object. According to an embodiment,
the at least one processor 310 may analyze the total operation time

total operation time period (e.g., 5 hours) to a plurality of time
periods. In addition, the at least one processor 310 may control at
least one of the angle of each vane, the temperature set on the air
conditioner, and the volume of air flowing toward the object in
each time period (e.g., 1 hour) of the divided time periods to
differ from at least one of the angle of each vane, the temperature
set on the air conditioner, and the volume of air flowing toward
the object in a previous time period of the each time period. The
at least one processor 310 may control the air conditioner 200 to
be operated at a first temperature and control the wind direction
controller 340 to automatically swing the at least one vane for a
first time period (e.g., 0 to 60 minutes of 5 hours) among the
divided plurality of time periods. The at least one processor 310
may control the wind direction controller 340 to automatically
swing the at least one vane for a predetermined first sub-time
period (e.g., 20 minutes) of the first time period (e.g., between 0
minutes and 60 minutes of 5 hours).
[0087] FIG. 6 is a flowchart showing an example process of
controlling an air conditioner.
[0088] Hereinafter, a process of controlling the air conditioner
according to another embodiment of the present disclosure is
described in detail with reference to FIG. 6.
[0089] According to an embodiment, at least one processor 310 may
determine whether an instruction for activating a concentration
enhancing mode is input from a user based on a signal received from
a remote control device 270 (S610). For example, when the user
operates the air conditioner 200 in the concentration enhancing
mode, the user may input an operation in the concentration
enhancing mode using a button 271 of the remote control device 270.
The remote control device 270 transmits, to the air conditioner
200, a signal including an instruction input by pressing the button
271 and the air conditioner 200 may receive the signal including
the instruction using the communicator 350. The air conditioner 200
may determine that the user has selected the concentration
enhancing mode based on the received signal. The signal may include
information on total operation time period for which the air
conditioner 200 is operated and the total operation time period may
be set by the user.
[0090] According to an embodiment, the at least one processor 310
may activate a concentration enhancing mode and activate a vision
camera (S612). The at least one processor 310 may operate the air
conditioner 200 in the concentration enhancing mode based on the
received signal and activate the vision camera of the motion
sensing sensor 260.
[0091] According to an embodiment, the at least one processor 310
may identify a user (S614). The at least one processor 310 may
control at least one of an infrared sensor of the temperature
measurement sensor 321 and at least one motion sensing sensor of
the motion sensing sensor 260 to identify a user's current
position.
[0092] According to an embodiment, the at least one processor 310
may identify whether the user is currently drowsing (S616). The at
least one processor 310 may control the motion sensing sensor 260
to determine whether the user's body portion (e.g., the head)
periodically nods. For example, if the motion sensing sensor 260
determines that that the user's body portion (e.g., the head)
periodically nods, the at least one processor 310 may identify that
the user is currently drowsing. For example, if the motion sensing
sensor 260 determines that the user's body portion (e.g., the head)
is not periodically nodding, the at least one processor 310 may
identify that the user is not drowsing currently.
[0093] According to an embodiment, the at least one processor 310
may control at least one of a wind direction determined based on
the adjustment of the vane angle, a temperature, or air volume of
the air conditioner in a predetermined time period unit (S618). If
the user is not identified by the at least one processor 310 at
S614 or the at least one processor identifies that the user is not
drowsing at S616, the at least one processor 310 may control at
least one of an angle of each of at least one among the vane 210,
220, 230, and 240 adjusted by the wind direction controller 240,
the temperature set on the air conditioner 200, and the air volume
controlled by the air volume controller 330 in the predetermined
time period unit. The at least one processor 310 may analyze
information on the total operation time period included in the
received signal and divide the total operation time period (e.g., 5
hours) into a plurality of time periods (e.g., a first time period
of 0 minutes to 60 minutes, a second time period of 60 minutes to
120 minutes, a third time period of 120 minutes to 180 minutes, a
fourth time period of 180 minutes to 240 minutes, and a fifth time
period of 240 minutes to 300 minutes). In addition, the at least
one processor 310 may control the at least one of the vane angle,
the temperature set on the air conditioner, and the volume of air
flowing toward the object in each time period (e.g., 1 hour) among
the divided time periods to differ from the at least one of the
vane angle, the temperature set on the air conditioner, and the
volume of air flowing toward the object in the previous time period
of the each time period.
[0094] According to an embodiment, the at least one processor 310
may control at least one of the wind direction determined through
the adjustment of the vane angle, the temperature, or the air
volume of the air conditioner in a predetermined time period unit
based on the user's current position. (S620). When the processor
310 identifies that the user is drowsing at S616, the at least one
processor 310 may control the wind direction controller 340 to
adjust angles of the at least one vane 210, 220, 230, and 240 and
face the at least one vane 21, 220, 230, and 240 toward the user.
In addition, the at least one processor 310 may adjust the
temperature set on the air conditioner 200 and control the air
volume controller 330 to adjust the air volume. The at least one
processor 310 may perform the adjustment in the predetermined time
period unit. The at least one processor 310 may divide the total
operation time period (e.g., 5 hours) into a plurality of time
periods (e.g., the first time period of 0 minutes to 60 minutes,
the second time period of 60 minutes to 120 minutes, the third time
period of 120 minutes to 180 minutes, the fourth time period of 180
minutes to 240 minutes, and the fifth time period of 240 minutes to
300 minutes). In addition, the at least one processor 310 may
control the at least one of the angle of each vane, the temperature
set on the air conditioner, and the volume of air flowing toward
the object in each period (e.g., 1 hour) among the divided time
periods to differ from the at least one of the angle of each vane,
the temperature set on the air conditioner, and the volume of air
flowing toward the object in the previous time period of the each
time period. The at least one processor 310 may adjust the angle of
each vane, the temperature set on the air conditioner, and the air
volume based on the current position of the object.
[0095] FIG. 7 is a flowchart showing an example process of
controlling an air conditioner.
[0096] Hereinafter, the process of controlling the air conditioner
according to another embodiment of the present disclosure is
described in detail with reference to FIG. 7.
[0097] According to an embodiment, at least one processor 310 may
activate a concentration enhancing mode (S710). The at least one
processor 310 may receive, from a remote control device 270, a
signal including an instruction for the concentration enhancing
mode based on the concentration enhancing mode input using the
button 271 of the remote control device 270. The signal may include
information on the total operation time period for which the air
conditioner 200 operates, and the total operation time may be set
by a user. For example, when the user wants to operate the air
conditioner 200 in the concentration enhancing mode for a certain
time period (e.g., 5 hours), the signal may include information on
the total operation time period (e.g., 5 hours) set by the
user.
[0098] According to an embodiment, the at least one processor 310
may determine whether the operation time period of the air
conditioner corresponds to a first period or a fifth period (S712).
The at least one processor 310 may determine whether a time period
during which the air conditioner 200 is operating in the
concentration enhancing mode corresponds to the first period (e.g.,
0 to 60 minutes) or the fifth period (e.g., 240 to 300 minutes) of
the total operation time period (e.g., 5 hours).
[0099] According to one embodiment, the at least one processor 310
may set the temperature of the air conditioner to the first
temperature (S714). When the at least one processor 310 determines
that the operation time period of the air conditioner 200
corresponds to the first period or the fifth period, the at least
one processor 310 sets the temperature of the air conditioner 200
to a first temperature (e.g., 27 Celsius degrees). The first
temperature may include an initial set temperature. The at least
one processor 310 may periodically check the current temperature
and determine that the checked current temperature is the same as
the first temperature.
[0100] According to an embodiment, the at least one processor 310
may determine whether the operation time period of the air
conditioner corresponds to the first period (S716). The at least
one processor 310 may determine that the operation time period
corresponds to the first period (e.g., 0 to 60 minutes) of the
total operation time period (e.g., 5 hours) while the air
conditioner 200 is operated to reach the first temperature.
[0101] According to an embodiment, the at least one processor 310
may automatically swing at least one vane for a predetermined time
period (S718). When the at least one processor 310 determines that
the operation time period of the air conditioner corresponds to the
first period (e.g., 0 minutes to 60 minutes) of the total operation
time period (e.g., 5 hours) at S716, the at least one processor 310
may automatically swing at least one vane 210, 220, 230 and 240 of
the air conditioner 200 for a predetermined time period (e.g., 20
minutes) to adjust the wind direction of the at least one vane 210,
220, 230, and 240. The automatic swing refers to swinging at least
one vane 210, 220, 230, and 240 of the air conditioner 200 from
0.degree. to 90.degree..
[0102] According to one embodiment, the at least one processor 310
may operate the air conditioner in a first mode (S720). The at
least one processor 310 automatically swings at least one vane 210,
220, 230, and 240 of the air conditioner 200 for the predetermined
time period (e.g., 20 minutes) and control the air conditioner 200
to be operated in the first mode. The first mode is a mode in which
the at least one processor 310 controls the air volume controller
330 to adjust the volume of air discharged through the at least one
vane 210, 220, 230, and 240 to first air volume (e.g., high air
volume). The first mode is a mode in which the at least one
processor 310 controls the wind direction controller 340 to move
the at least one vane within a first angular range (e.g., within
0.degree. to 30.degree.) for a predetermined second sub-time period
(e.g., 60 seconds), and after the predetermined second sub-time
period, move the at least one vane within a second angular range
(e.g., within 30.degree. to 80.degree.) that is greater than the
first angular range for a predetermined third sub-time period
(e.g., 60 seconds). In addition, the first mode is a mode in which
the at least one processor 310 controls the wind direction
controller 340 to automatically swing the at least one vane for a
predetermined fourth sub-time period (e.g., 90 seconds) after the
predetermined third sub-time period. The at least one processor 310
may repeatedly perform the above operation for a rest time period
(e.g., 40 minutes) of the first period (e.g., 0 to 60 minutes)
after the predetermined time period (e.g., 20 minutes) in the first
mode.
[0103] According to an embodiment, the at least one processor 310
may determine whether an operation time period of the air
conditioner corresponds to the first period (S722). The at least
one processor 310 periodically checks the operation time period of
the air conditioner 200 while the air conditioner 200 is operating
in the first mode to determine whether the operation time period of
the air conditioner 200 corresponds to the first period (e.g., 0
minutes to 60 minutes).
[0104] According to one embodiment, the at least one processor 310
may determine whether the operation time period thereof corresponds
to the fifth period (S724). The at least one processor 310 may
periodically check the operation time period of the air conditioner
200 while the air conditioner 200 is operating in the first mode.
In addition, when the at least one processor 310 determines that
the operation time period of the air conditioner 200 does not
correspond to the first period, the at least one processor 310 may
determine whether the operation time period of the air conditioner
200 corresponds to the fifth period (e.g., 240 to 300 minutes).
[0105] According to one embodiment, the at least one processor 310
may determine whether the operation time period of the air
conditioner 200 corresponds to the third period (S726). When the at
least one processor 310 determines that the operation time period
of the air conditioner 200 does not correspond to the fifth period,
the at least one processor 310 may determine whether the operation
time period of the air conditioner 200 exceeds a predetermined
total operation time period (e.g., 5 hours) (S736). When the at
least one processor 310 determines that the operation time period
of the air conditioner 200 does not exceed the total operation time
period, the process returns back to S712, and the at least one
processor 310 may determine that the operation time period of the
air conditioner corresponds to the fifth period (e.g., 240 to 300
minutes) (S712). When the at least one processor 310 determines
that the operation time period of the air conditioner 200 does not
correspond to the fifth period, the at least one processor 310 may
determine whether the operation time period of the air conditioner
200 corresponds to the third period (e.g., 120 to 180 minutes)
(S726).
[0106] According to one embodiment, the at least one processor 310
may operate the air conditioner at a second temperature (S728).
When the at least one processor 310 determines that the operation
time period of the air conditioner 200 corresponds to the third
period, the at least one processor 310 sets the temperature of the
air conditioner 200 to the second temperature (e.g., 28 Celsius
degrees). The second temperature (e.g., 28 Celsius degrees) may be
a temperature higher than the first temperature (e.g., 27 Celsius
degrees) by a preset temperature (e.g., 1 Celsius degree). The at
least one processor 310 may periodically check the current
temperature and determine that the checked current temperature is
the same as the second temperature.
[0107] According to one embodiment, the at least one processor 310
may operate the air conditioner in a second mode and a third mode
(S730). The at least one processor 310 may control the air
conditioner 200 to sequentially and repeatedly operate the air
conditioner 200 in the second mode and the third mode. The second
mode is a mode in which the at least one processor 310 operates the
air conditioner to adjust the first temperature (e.g., 27 Celsius
degrees) in the first mode to a second temperature (e.g., 28
Celsius degrees) that is greater than the first temperature by the
predetermined temperature (e.g., 1 Celsius degree) and the at least
one processor 310 controls the air volume controller 330 to adjust
the air volume to the second air volume (e.g., low air volume) that
is less than the first air volume (e.g., high air volume). The
third mode is a mode in which the at least one processor 310
controls the air volume controller 330 to adjust the second air
volume in the second mode to the first air volume.
[0108] For example, the second mode is a mode in which the at least
one processor 310 controls the air volume controller 330 to adjust
the volume of air discharged through the at least one vane 210,
220, 230, and 240 to the second air volume (e.g., low air volume).
The second mode is a mode in which the at least one processor 310
controls the wind direction controller 340 to move the at least one
vane within a first angular range (e.g., within 0.degree. to
30.degree.) for a predetermined second sub-time period (e.g., 60
seconds), and after the predetermined second sub-time period, to
move the at least one vane within a second angular range (e.g.,
within 30.degree. to 80.degree.) that is greater than the first
angular range for the predetermined third sub-time period (e.g., 60
minutes). The second mode is a mode in which, after the
predetermined third sub-time period, the at least one processor 310
controls the wind direction controller 340 to automatically swing
the at least one vane for a predetermined fourth sub-time period
(e.g., 90 seconds).
[0109] In addition, the third mode is a mode in which the at least
one processor 310 controls the air volume controller 330 to adjust
the air volume discharged through the at least one vane 210, 220,
230, and 240 to the first air volume (e.g., high air volume). In
addition, the third mode is a mode in which the at least one
processor 310 controls the wind direction controller 340 to move
the at least one vane within the first angular range (e.g., within
0.degree..about.30.degree.) for the predetermined second sub-time
period (e.g., 60 seconds), and after the predetermined second
sub-time period, the at least one vane moves within a second
angular range (e.g., within 30.degree..about.80.degree.) that is
greater than the first angular range for a predetermined third
sub-time period (e.g., 60 seconds). In addition, after the
predetermined third sub-time period, the third mode is a mode in
which the at least one processor 310 controls the wind direction
controller 340 to automatically swing the at least one vane for the
predetermined fourth sub-time period (e.g., 90 seconds).
[0110] The at least one processor 310 may control the air
conditioner 200 to be operated repeatedly and alternately in the
second mode and the third mode in the second period (e.g., 60 to
120 minutes).
[0111] According to an embodiment, the at least one processor 310
may determine whether the operation time period of the air
conditioner corresponds to the second period (S732). The at least
one processor 310 periodically checks the operation time period of
the air conditioner 200 while the air conditioner 200 is repeatedly
operated in the second mode and the third mode to determine whether
the operation time period of the air conditioner 200 corresponds to
the second period (e.g., 60 to 120 minutes).
[0112] According to one embodiment, the at least one processor 310
may determine whether the operation time period of the air
conditioner corresponds to the fourth period (S734). The at least
one processor 310 may periodically check the operation time period
of the air conditioner 200 while the air conditioner 200 is
repeatedly operated in the second mode and the third mode. In
addition, when the at least one processor 310 determines that the
operation time period of the air conditioner 200 does not
correspond to the second period (e.g., 60 minutes to 120 minutes),
the at least one processor 310 may determine that the operation
time period of the air conditioner 200 corresponds to the fourth
period (e.g., 180 to 240 minutes).
[0113] According to one embodiment, the at least one processor 310
may determine whether the operation time period of the air
conditioner is greater than the total operation time period (S736).
When the at least one processor 310 determines that the operation
time period of the air conditioner 200 does not correspond to the
fourth period, the at least one processor 310 may determine whether
the operation time period of the air conditioner 200 exceeds the
predetermined total operation time period (e.g., 5 hours) (S736).
When the at least one processor 310 determines that the operation
time period of the air conditioner 200 does not exceed the total
operation time period, the process returns back to S712, and the at
least one processor 310 may determine whether the operation time
period of the air conditioner corresponds to the fifth period
(e.g., 240 to 300 minutes) (S712). When the at least one processor
310 determines that the operation time period of the air
conditioner 200 does not correspond to the fifth period, the at
least one processor 310 may determine whether the operation time
period of the air conditioner 200 corresponds to the third period
(e.g., 120 to 180 minutes) (S726).
[0114] According to one embodiment, the at least one processor 310
may operate the air conditioner at a third temperature (S738). When
the at least one processor 310 determines that the operation time
period of the air conditioner 200 does not correspond to the third
period, the at least one processor 310 sets the temperature of the
air conditioner 200 to the third temperature (e.g., 29 Celsius
degrees). The third temperature (e.g., 29 Celsius degrees) may be a
temperature higher than the second temperature (e.g., 28 Celsius
degrees) by a preset temperature (e.g., 1 Celsius degree). The at
least one processor 310 may periodically check the current
temperature and determine that the checked current temperature is
the same as the third temperature.
[0115] According to one embodiment, the at least one processor 310
may operate the air conditioner in the first mode (S740). The first
mode at S740 may have the same set time and angular range of each
vane as the first mode at S720. Alternatively, the first mode at
S740 may have different set time or angular range of at least one
vane from the set time or the angular range of the as least one
vane in the first mode at S720.
[0116] According to an embodiment, the at least one processor 310
may determine whether the operation time period of the air
conditioner 200 corresponds to the third period (S742). The at
least one processor 310 periodically checks the operation time
period of the air conditioner 200 while the air conditioner 200 is
operated in the first mode to determine whether the operation time
period of the air conditioner 200 corresponds to the third period
(e.g., 120 minutes to 180 minutes).
[0117] According to an embodiment, the at least one processor 310
may deactivate a concentration enhancing mode (S744). When the at
least one processor 310 determines that the operation time period
of the air conditioner 200 does not correspond to the third period,
at least one processor 310 may determine that the operation time
period of the air conditioner 200 exceeds the total operation time
period (e.g., 5 hours) of the air conditioner 200. When the at
least one processor 310 determines that the operation time period
of the air conditioner 200 exceeds the total operation time period
(e.g., 5 hours), the at least one processor 310 may deactivate the
concentration enhancing mode. The at least one processor 310 may
deactivate the concentration enhancing mode that is activated
according to user's requests. After the concentration enhancing
mode is deactivated, the at least one processor 310 may terminate
the operation of the air conditioner 200 or control the air
conditioner through cooling and heating.
[0118] At least one of the time period or the angular ranges
described above is only an example, and may be variably changed or
adjusted to other times or other angular ranges.
[0119] FIG. 8 is a flowchart showing an example operation process
of an air conditioner in a first mode.
[0120] Hereinafter, an operation process of the air conditioner in
the first mode according to an embodiment of the present disclosure
is described in detail with reference to FIG. 8 as follows. The
processes of FIG. 8 may be performed in at least one of the
processes (e.g., S720, S730, and S740) of FIG. 7.
[0121] According to an embodiment, the at least one processor 310
may operate the at least one vane within a first angular range for
a first time period (S810). The at least one processor 310 may
control the at least one vane 210, 220, 230, and 240 of the air
conditioner 200 to move within a first angular range (e.g., within
0.degree. to 30.degree.) for a predetermined first sub-time period
(e.g., 60 seconds) to discharge indirect wind. The first angular
range (e.g., within 0.degree. to 30.degree.) may be an angular
range in which the wind does not directly flows toward an occupant
(or a user), but flows toward a periphery of the occupant (e.g.,
above the head or in a direction not toward the occupant). The at
least one processor 310 may control the at least one sensor (e.g.,
the motion sensing sensor) disposed at an outer portion of the air
conditioner 200 to determine presence or absence of an occupant and
the position of the occupant. The at least one processor 310 may
control the wind direction controller 340 to gradually increase the
angle of the at least one vane from 0.degree. to 30.degree. during
the predetermined sub-time period (e.g., 60 seconds) and control
the wind direction controller 340 to gradually decrease the angle
of the at least one vane from 30.degree. to 0.degree.. The at least
one processor 310 may control the wind direction controller 340 to
move at least one vane within the first angular range during the
predetermined time period (e.g., 60 seconds) and control the air
volume controller 330 to adjust the air volume to low air volume,
medium air volume, or high air volume.
[0122] According to one embodiment, the at least one processor 310
may operate the at least one vane within a second angular range for
a second time period (S810). The at least one processor 310 may
control the at least one vane 210, 220, 230, and 240 of the air
conditioner 200 to move within the second angular range (e.g.,
within 30.degree. to 90.degree.) for the predetermined second
sub-time period (e.g., 60 seconds) to discharge direct wind. The
first angular range (e.g., within 30.degree. to 90.degree.) may be
an angular range in which the wind directly flows toward the
occupant (or the user). The at least one processor 310 may control
the wind direction controller 340 to gradually increase the angle
of the at least one vane from 30.degree. to 90.degree. during the
predetermined time period (e.g., 60 seconds) and control the wind
direction controller 340 to gradually decrease the angle of the at
least one vane from 90.degree. to 30.degree.. The at least one
processor 310 may control the wind direction controller 340 to move
the at least one vane within the second angular range for the
predetermined time period (e.g., 60 seconds) and control the air
volume controller 330 to adjust the air volume to low air volume,
mediate air volume, or high air volume.
[0123] According to one embodiment, the at least one processor 310
may automatically swing the at least one vane to operate for a
third time period (S814). The at least one processor 310 may
automatically swing the at least one vane 210, 220, 230, and 240 of
the air conditioner 200 during the third time period (e.g., 90
seconds) to adjust the angle of the at least one vane 210, 220,
230, and 240. The automatic swing refers to swinging of at least
one vane 210, 220, 230, and 240 of the air conditioner 200 from
0.degree. to 90.degree.. According to an embodiment, the at least
one processor 310 may repeatedly perform the steps (e.g., S810,
S812, and S814) in a predetermined time period unit (e.g., 1 hour
unit).
[0124] FIG. 9 is an exemplary view showing example direct wind and
indirect wind discharged based on a user's position.
[0125] Referring to FIG. 9, according to an embodiment of the
present disclosure, when a user is located at a first position 910,
direct winds 911 and 912 are discharged from a first vane 20 among
at least one vane 210, 220, 230, and 240 of the air conditioner 200
and directly flow toward the user. Indirect wind 913 is discharged
from the first vane 210 among the at least one vane 210, 220, 230,
and 240 of the air conditioner 200 and directly flows toward the
user.
[0126] According to an embodiment, when the user is located at a
second position 920, direct wind 913 is discharged from the first
vane 210 among the at least one vane 210, 220, 230, and 240 of the
air conditioner 200 and directly flows toward the user. The
indirect winds 911 and 912 are discharged from the first vane 210
among the at least one vane 210, 220, 230, and 240 of the air
conditioner 200 and directly flow toward the user.
[0127] The at least one processor 310 controls the wind direction
controller 340 to face the at least one vane 210, 220, 230, and 240
of the air conditioner 200 toward the user. Based on the above
operations, the wind direction controller 340 may directly face the
wind discharged from the at least one vane toward the user (e.g.,
discharge the direct wind) or indirectly face the wind discharged
from the at least one vane toward the user (e.g., discharge the
indirect wind).
[0128] At least one processor 310 may control a least one motion
sensing sensor disposed at the outer portion of the air conditioner
200 to identify a position of the user and determine whether a body
portion (e.g., the head) of the identified user is periodically
moving. For example, when the user's body portion (e.g., the head)
is periodically moving, the at least one processor 310 may identify
that the user is currently drowsing. When the at least one
processor 310 identifies that the user is currently drowsing, the
at least one processor 310 may automatically activate a
concentration enhancing mode. According to an embodiment, at least
one of the angle of each of vanes, a temperature set on the air
conditioner, and volume of air flowing toward the subject may be
changed compared to a predetermined value based on the position of
the user, a distance between the user and the air conditioner, a
direction of the vane of the air conditioner.
[0129] FIG. 10 is an exemplary view showing an example of at least
one vane angle, a set temperature, and air volume. FIG. 11A is an
exemplary view showing example opening/closing of at least one
vane. FIG. 11B is an exemplary view showing an example adjusted
angle of a vane.
[0130] Referring to FIGS. 10, 11A, and 11B, at least one processor
310 may control a communicator 350 to receive a signal from a
remote control device 270 and identify total operation time period
information included in the received signal. The total operation
time period is a user set time period for which the air conditioner
200 is operated in a concentration enhancing mode. The at least one
processor 310 may divide the total operation time period (e.g., 5
hours) into a plurality of time periods 1010, 1020, 1030, 1040, and
1050 and control at least one of the angle of each vane, the
temperature set on the air conditioner 200, and volume of air
flowing toward the user in each time period unit (e.g., 1 hour
unit) among the divided time periods. The at least one processor
310 may control the at least one of the angle of each of vanes, the
temperature, and the air volume in each time period to differ from
the at least one of the angle of each of vanes, the temperature,
and the air volume in a previous time period of the each time
period and operate the air conditioner 200 based on the controlled
configurations.
[0131] For example, during a first time period 1010 of the total
operation time period (e.g., 5 hours), the at least one processor
310 may control the air conditioner 200 to be operated in the
concentration enhancing mode like as a first pattern 1011 in which
the at least one processor 310 adjusts the air volume to high wind
volume, a temperature to a set temperature (T0), the angle of the
vane from 20.degree. to 80.degree.. For a second time period 1020
of the total operation time period (e.g., 5 hours), the at least
one processor 310 may operate the air conditioner 200 like as a
second pattern 1021 in which the at least one processor 310 adjusts
the air volume of the air conditioner 200 to high air volume and
medium air volume, the temperature to a set temperature (T0+1), and
the angle of the vane from 20.degree. to 80.degree.. For a third
time period 1030 of the total operation time period (e.g., 5
hours), the at least one processor 310 may operate the air
conditioner 200 like as a third pattern 1031 in which the at least
one processor 310 adjusts the air volume of the air conditioner 200
to high air volume, the temperature to a set temperature (T0+2),
and the angle of the vane from 20.degree. to 80.degree.. For a
fourth time period 1040 of the total operation time period (e.g., 5
hours), the at least one processor 310 may operate the air
conditioner 200 like as a fourth pattern 1041 in which the at least
one processor 310 adjusts the air volume of the air conditioner 200
to high air volume and medium air volume, the temperature to a set
temperature (T0+1), and the angle of the vane from 20.degree. to
80.degree.. The operation pattern of the air conditioner 200 for
the second time period 1020 may be identical to the operation
pattern of the air conditioner 200 for the fourth time period 1040.
In addition, for a fifth time period 1050 of the total operation
time period (e.g., 5 hours), the at least one processor 310 may
operate the air conditioner 200 like as a fifth pattern 1051 in
which the at least one processor 310 adjusts the air volume of the
air conditioner 200 to high air volume, the temperature to a set
temperature (T0), and the angle of the vane from 20.degree. to
80.degree..
[0132] Referring to FIGS. 11A and 11B, an angle of each of vanes
may be variously adjusted. For example, when wind discharged from
the air conditioner 200 is indirect wind, the angle of the at least
one vane may be gradually adjusted from a first angle 1110 to a
second angle 1120. In addition, when the wind discharged from the
air conditioner 200 is direct wind, the angle of the at least one
vane may be gradually adjusted to a third angle 1130, a fourth
angle 1140, a fifth angle 1150, a sixth angle 1160, and a seventh
angle 1170. The angle of the at least one vane may be adjusted to
the third angle 1130 in a reverse sequence after the seventh angle.
At least one of the first angle, the second angle, the third angle,
the fourth angle, the fifth angle, the sixth angle, or the seventh
angle may be adjusted to have a different angle value.
[0133] FIG. 12A is an exemplary view showing vane angles in each
mode and operation time periods at each angle adjusted to have
different values. FIG. 12B is an exemplary view showing an example
result of adjusting angles in each mode and operation time periods
at each angle to have different values.
[0134] Referring to FIGS. 12A and 12B, a first experiment 1210 is
an example in which an air conditioner is operated at 20.degree. of
angle of at least one vane for 60 seconds, at 45.degree. of angle
of at least one vane for 60 seconds, and from 40.degree. to
80.degree. of angle of the at least one vane for 90 seconds. A
second experiment 1220 is an example in which the air conditioner
is operated at 20.degree. of angle of at least one vane for 60
seconds, at 45.degree. of angle of the at least one vane for 60
seconds, and at 40.degree. to 80.degree. of angle of the at least
one vane for 120 seconds.
[0135] A third experiment 1230 is an example in which the air
conditioner is operated at 20.degree. of angle of at least one vane
for 60 seconds, at 45.degree. of angle of the at least one vane for
60 seconds, and from 40.degree. to 80.degree. of angle of the at
least one vane for 90 seconds. A fourth experiment 1240 is an
example in which the air conditioner is operated at 20.degree. of
angle of at least one vane for 60 seconds, at 40.degree. of angle
of the at least one vane for 60 seconds, and from 20.degree. to
80.degree. of angle of the at least one vane for 90 seconds.
According to the experiments executed under the above conditions,
the higher the stimulus is, the higher the concentration is in the
fourth experiment as shown in FIG. 12B.
[0136] FIG. 13 is an exemplary view showing an example result of
measuring brainwave before and after executing a concentration
enhancing mode.
[0137] Referring to FIG. 13, an alpha level and a beta level are
significantly increased after executing the concentration enhancing
mode than before executing the concentration enhancing mode. The
alpha level refers to a person's comfort and the beta level refers
to a person's concentration and awakening. The higher the alpha
level is, the higher the comfort index is, and the higher the beta
level is, the higher the concentration or awakening is. For
example, the alpha wave ratio before executing the concentration
enhancing mode was 12.4%, but the alpha wave ratio after executing
the concentration enhancing mode was increased to 15%, indicating
that the user's comfort was improved. In addition, the beta wave
ratio before executing the concentration enhancing mode was 17.6%,
but the beta wave ratio after executing the concentration enhancing
mode was increased to 24.1%, indicating that the user's
concentration and awakening were improved.
[0138] Each step in each of the flowcharts described above may be
operated regardless of the illustrated sequence, or may be
performed simultaneously. In addition, at least one component of
the present disclosure and at least one operation performed by the
at least one component may be implemented with hardware and/or
software.
