According to an embodiment, the air volume controller 330 may control the amount of air discharged through the first discharger 201 and the second discharger 202. For example, the air volume controller 330 may adjust a number of rotations of the blowing fan based on a control signal provided by the processor 310 and may control the amount of air discharged through the first discharger 201 and the second discharger 202.
According to an embodiment, the wind direction controller 340 may adjust an angle of the first discharger 110 to control a first direction of air discharged through the first discharger 201 and may adjust an angle of the second discharger 120 to control a second direction of air discharged through the second discharger 202.

According to an embodiment, the motion sensing sensor 140 may detect the occupants within the indoor space where the air conditioner 100 is installed. The motion sensing sensor 140 may be disposed to be rotatable on an outer surface of the air conditioner 100. The motion sensing sensor 140 may detect a user taking a sleep in the indoor space where the air conditioner 100 is installed. The motion sensing sensor 140 may scan the indoor space by rotating under the control of the processor 310 and may detect the occupants located within the indoor space. The motion sensing sensor 140 may detect occupants through various methods. For example, the motion sensing sensor 140 may detect the occupants using infrared rays. The motion sensing sensor 140 may also detect the occupants using radiant heat emitted from the occupant and may detect the occupants by using a camera. The motion sensing sensor 140 may include a vision sensor. In addition, the motion sensing sensor 140 may detect the occupants through various methods of identifying human body (e.g., the occupant).
The detection operation of the motion sensing sensor 140 may be performed every preset detection period (e.g., for 10 seconds) and the motion sensing sensor 140 may provide a processor 310 described below with detection information on the detection of the occupant.
According to an embodiment, the processor 310 may acquire an amount of activity of the occupant based on a location of the occupant detected by the motion sensing sensor 140. In addition, the processor may include at least one circuit (or a processor) to control the temperature of the air conditioner 100 based on the acquisition result. The activity amount is a parameter indicating a degree of movement of the occupant and may be determined based on a movement distance of the occupant or a parameter proportional to the movement distance of the occupant. The processor 310 may identify changes in location of the occupant based on the location of the occupant detected at every detection time period and may acquire an amount of activity of the occupant based on the changes in the location of the occupant. In some examples, the processor 310 may identify the location of the occupant detected by the motion sensing sensor 140 and acquire the activity amount of the occupant based on the amount of changes in occupant's location during a reference time period.
According to an embodiment, the processor 310 may detect the movement of the occupant when the air conditioner 100 is operated based on the first temperature in a sleep control mode. In addition, based on the amount of movement of the occupant being less than a predetermined amount and the operation time period of the air conditioner 100 at the first temperature being exceeding a first threshold time period, the processor 310 may control the air volume controller to operate the air conditioner based on a second temperature.

Hereinafter, a method for controlling a temperature according to an embodiment of the present disclosure is described in detail with reference to
According to an embodiment, a processor 310 may operate the air conditioner based on a first temperature (S510). The processor 310 may operate the air conditioner 100 to approach an indoor temperature of the area (e.g., the room, the living room, and the like) where the air conditioner 100 is located to the first temperature. The processor 310 may periodically check the indoor temperature during the operation of the air conditioner 100 to determine whether the indoor temperature reaches the first temperature. In addition, the processor 310 may activate a human body sensing mode to detect an object (e.g., a person) in an area (e.g., the room, the living room, and the like) where the air conditioner 100 is located. The processor 310 may activate the motion sensing sensor 140 to operate the air conditioner in the human body sensing mode. In addition, when a current time is a time to sleep (e.g., after 9 p.m.), the processor 310 may activate a sleep control mode. Alternatively, the processor 310 may activate at least one of the sleep control mode or the human body sensing mode based on the motion sensing sensor 140 (e.g., a vision camera) detecting that the object (e.g., a person) lies on the bed.
According to an embodiment, the processor 310 may determine whether the movement of the object is detected (S512). The processor 310 may determine whether the object is currently moving or not moving by using the motion sensing sensor 140. The processor 310 may determine that the object may not move by using the vision camera of the motion sensing sensor 140 and may determine that the object slightly moves. For example, the processor 310 may determine that the object does not move based on the detection of the insignificant movement of the object. The processor 310 may determine whether the object is currently taking a deep sleep, or is taking a non-deep sleep (e.g., the REM sleep), or is not taking a sleep based on the degree of movement of the object (e.g., the person).
According to an embodiment, the processor 310 may determine whether the operation time period of the air conditioner at the first temperature exceeds a first threshold time period (S514). The processor 310 may determine whether a time period for which the air conditioner 100 operates to approach the indoor temperature (e.g., the room and the living room) where the air conditioner 100 is disposed to the first temperature exceeds the first threshold time period. The processor 310 may periodically measure the time period for which the air conditioner 100 operates when the indoor temperature is the first temperature.
According to an embodiment, the processor 310 may operate the air conditioner based on the second temperature (S516). Based on the operation time period of the air conditioner at first the temperature being exceeding the first threshold time period, the processor 310 may operate the air conditioner 100 to approach an indoor temperature of the area where the air conditioner 100 is disposed (e.g., the room, the living room, and the like) to a second temperature. When the operation time period of the air conditioner at the first temperature exceeds the first threshold time period, the processor 310 may control the air volume controller 330 to operate the air conditioner 100 based on the second temperature. The processor 310 may periodically check the indoor temperature during the operation of the air conditioner 100 to determine the indoor temperature reaches the second temperature. The first temperature may be higher than the predetermined second temperature.
According to an embodiment, the processor 310 may determine whether the operation time period of the air conditioner at the second temperature exceeds a second threshold time period (S518). The processor 310 may determine whether a time period for which the air conditioner 100 operates to approach the indoor temperature of the area where the air conditioner 100 is disposed (e.g., the room, the living room, and the like) to a second temperature exceeds a second threshold time period. The processor 310 may periodically measure the time period for which the air conditioner 100 operates when the indoor temperature is the second temperature.
According to an embodiment, the processor 310 may operate the air conditioner based on the first temperature (S520). Based on the operation time period of the air conditioner at the second temperature being exceeding the second threshold time period, the processor 310 may operate the air conditioner 100 to approach the inner temperature of the area where the air conditioner 100 is disposed (e.g., the room, the living room, and the like) to the first temperature. When the operation time period of the air conditioner at the second temperature exceeds the second threshold time period, the processor 310 may control the air volume controller 330 to operate the air conditioner 100 based on the first temperature. The processor 310 may periodically check the indoor temperature during operation of the air conditioner 100 and may determine whether the indoor temperature reaches the first temperature.
According to an embodiment, the processor 310 may determine whether a total operation time period exceeds the third threshold time period (S522). The processor 310 may determine the total operation time period for which the air conditioner 100 is operated when the air conditioner is operated in a human body sensing mode. The processor 310 may determine whether the determined total operation time period exceeds a third threshold time period. For example, based on the identified total operation time period being exceeding the third threshold time period, the processor 310 may deactivate at least one of the human body sensing mode or the sleep control mode.
For example, based on the determined total operation time period not exceeding the third threshold time period, the process goes back to S514 to determine the operation time period of the air conditioner at the first temperature exceeds the first threshold time period. Based on the movement of the object not detected at S512, the processor 310 may operate the air conditioner 100 based on each temperature for a predetermined threshold time period to approach the inner temperature to the first temperature or the second temperature. For example, the processor 310 may alternately operate the air conditioner 100 at the first temperature and the second temperature for a predetermined total operation time period. The processor 310 may increase the second threshold time period at the second temperature by a predetermined time period based on an elapse of time during alternate operation of the air conditioner based on the first temperature and the second temperature.
Hereinafter, a method for controlling the temperature by the temperature control apparatus according to another embodiment of the present disclosure is described in detail with reference to
According to an embodiment, a processor 310 may activate a sleep control mode (S610). The processor 310 may activate the sleep control mode based on the an input to control sleep receiving from a user. According to an embodiment, the processor 310 may activate the sleep control mode when the motion sensing sensor 140 (e.g., a vision camera) determines that an object (e.g., a person) lies on the bed.
According to an embodiment, the processor 310 may activate a human body sensing mode (S612). The processor 310 may activate the human body sensing mode based on an input for detecting the human body being received from a user. According to an embodiment, the processor 310 may activate the human body sensing mode based on determination that the object (e.g., the person) lies on the bed, by the motion sensing sensor 140 (e.g., the vision camera). According to an embodiment, after the sleep control mode is activated, the human body sensing mode may be activated. After the human body sensing mode is activated, the sleep control mode may be activated. Alternatively, the human body sensing mode and the sleep control mode may be activated simultaneously.
According to an embodiment, the processor 310 may operate an air conditioner based on a first temperature (S614). The processor 310 may control cooling and heating of the air conditioner 100 to approach an indoor temperature of the area where the air conditioner 100 is located (e.g., the room, the living room, and the like) to the first temperature. The processor 310 may periodically check the indoor temperature during operation of the air conditioner 100 to determine whether the indoor temperature reaches the first temperature.
According to an embodiment, the processor 310 may detect a movement of the object (S616). The processor 310 may determine whether the object is currently moving or not by using the motion sensing sensor 140 (e.g., the vision camera). The processor 310 may determine that the object may not move by using the vision camera of the motion sensing sensor 140 and may determine that the object slightly moves. For example, when the movement of the object is insignificantly detected, the processor 310 may determine that the object does not move. The processor 310 may determine whether the object is currently taking a deep sleep, or is taking a non-deep sleep (e.g., the REM sleep), or is not taking a sleep based on the degree of the movement of the object (e.g., the person).
According to an embodiment, the processor 310 may determine whether an operation time period of the air conditioner exceeds a first threshold time period (e.g., 100 minutes) (S618). Based on the determination that the object (e.g., the person) does not move at S616 (e.g., based on the person sleeping), the processor 310 may measure a time period (e.g., an operation time period) for which cooling and heating is controlled to approach an indoor temperature of the area (e.g., the room, the living room, and the like) where the air conditioner 100 is disposed to the first temperature (or after the indoor temperature of the area reaches the first temperature). Further, the processor 310 may determine whether the measured time period exceeds the first threshold time period 701 (e.g., 100 minutes).
According to an embodiment, the processor 310 may operate the air conditioner based on a second temperature (S620). Based on the operation time period of the air conditioner at the first temperature being exceeding the first threshold time period 701, the processor 310 may control the cooling and the heating of the air conditioner 100 to approach the inner temperature of the area (e.g., the room, the living room, and the like) where the air conditioner 100 is disposed to the second temperature. Based on the operation time period of the air conditioner at the first temperature being exceeding the first threshold time period 701, the processor 310 may control an air volume controller 330 to operate the air conditioner 100 based on the second temperature. The processor 310 may periodically check the indoor temperature during the operation of the air conditioner 100 and may determine whether the periodically checked indoor temperature reaches the second temperature. The first temperature (e.g., 28 degree Celsius) may be higher than the second temperature (e.g., 27 degree Celsius) by a predetermined temperature (e.g., 1 degree Celsius).
According to an embodiment, the processor 310 may determine whether the operation time period of the air conditioner exceeds a second threshold time period (e.g., 120 minutes) (S622). The processor 310 may measure a time period 720 for which the cooling and heating is controlled (e.g., 20 minutes of operation time period) after the indoor temperature of the area (e.g., the room, the living room, and the like) where the air conditioner 100 is disposed reaches the second temperature. Alternatively, the processor 310 may measure a time period for which the air conditioner 100 operates (e.g., 120 minutes, where 120 minutes=100 minutes at S618+20 minutes after reaching the second temperature).

The first image 810 has a reddish color to determine a body temperature of a person turning over during sleep and the second image 811 is an image of person in sleep. A third image 812 shows an interior of the bedroom divided into a plurality of virtual areas and may indicate a place corresponding to the position of the person (e.g., a place corresponding to an angle of −8° and a distance of 2.7 m). The third image 812 may also show person's movement. A fourth image 813 corresponds to a graph showing a magnitude of a person's movement (e.g., activity amount). When the person turns over during sleep, the motion sensing sensor 140 of the temperature control apparatus 300 may detect the movement of the person turning over during sleep. The processor 310 of the temperature control apparatus 300 may graphically express an intensity of movement of the person. For example, when a person turns over during sleep as shown in the fourth image 813, the amount of activity increases (e.g., an amount of activity>1) shown using reference numeral 814.
