FIG. 1 is a block diagram illustrating a controlled for use in an air-conditioner in accordance with a preferred embodiment of the present invention. - Referring to
FIG. 1 , auser input unit 104 and aroom temperature sensor 106 are connected to input terminals of thecontroller 102 for controlling overall operations of the air-conditioner. Acompressor 108, anindoor unit fan 110, and adischarge blade 112 are connected to output terminals of thecontroller 102. A timer is contained in thecontroller 102. - The
user input unit 104 allows a user to enter a desired operation mode or desired temperature for the air-conditioner, such that the entered operation mode or temperature can be established. Theroom temperature sensor 106 detects room temperature. It is preferable that thecompressor 108 may be designed in the form of a variable capacity compressor according to an inverter control scheme or tandem scheme. It is preferable that theindoor unit fan 110 may be designed to have a variable rotation speed. Thedischarge blade 112 is installed at an outlet via which cool air is discharged from an indoor unit, such that it variably adjusts a discharge direction or a discharge area. - If the user-selected operation mode is a sleep mode, the
controller 102 basically operates thecompressor 108 at minimum capacity, and operates theindoor unit fan 110 at a minimum rotation number, such that it maintains a minimum cooling capacity. Thecontroller 102 adjusts a discharge direction of thedischarge blade 112 and an opening area of the same, such that it indirectly transmits cool air to a user instead of directly transmitting the cool air. However, if a rapid cooling operation is required, at least one of the cooling capacity of thecompressor 108, a rotation number of theindoor unit fan 110, and a cooling-air discharge area is increased, such that the cooling capacity of thecompressor 108 is greatly increased. Preferably, if all of the cooling capacity of thecompressor 108, a rotation number of theindoor unit fan 110, and a cooling-air discharge area is increased, the above-mentioned cooling capacity of thecompressor 108 is more greatly increased than in the aforementioned case. -
FIG. 2 is a graph illustrating temperature characteristics of a sleep mode for use in an air-conditioner in accordance with a preferred embodiment of the present invention.FIG. 3 is a flow chart illustrating a method for controlling a sleep mode of an air-conditioner according to temperature characteristics of the sleep mode shown inFIG. 2 in accordance with a preferred embodiment of the present invention. - As can be seen from
FIGS. 2∼3 , the sleep mode of the air-conditioner according to the present invention includes a sleep-entrance stage 202, a deep-sleep stage 204, and a wake-upstage 206. The sleep mode shown inFIGS. 2∼3 is established to have a standard execution time of 8 hours as a total execution time. - The sleep-
entrance stage 202 is indicative of a predetermined period of time from a first time at which the user selects the sleep mode to a second time at which the user falls asleep, and performs a rapid cooling operation until a room temperatures reaches a first temperature Ti-z less than a setup temperature Ti atstep 302. In other words, the sleep-entrance stage 202 performs the rapid cooling mode capable of rapidly lowering a room temperature from a current temperature of t20 to the first temperature Ti-z equal to a specific temperature t21, such that a user's skin temperature is reduced to an appropriate temperature and the central nervous system associated with a human-body temperature control function is minimized. The rapid cooling time equal to the time from t20 to t21 may be established in the range from a minimum of several minutes to a maximum of 1 hour. During the rapid cooling mode, the cooling capacity of thecompressor 108 and the rotation number of theindoor unit fan 110 are increased, and thedischarge blade 112 is controlled to adjust a discharge area and a discharge direction, such that air in the room is easily mixed. During the remaining time (i.e., a time from t21 to t22) of the sleep-entrance stage 202, the room temperature is maintained at the first temperature Ti-z equal to the rapid cooling temperature, such that the user's skin temperature is continuously lowered atstep 304. A temperature drop range "z" at the sleep-entrance stage 202 is in the range from 1°C to 4°C, and a total operation time of the sleep-entrance stage 202 is in the range from a minimum of 30 minutes to a maximum of 3 hours. - The deep-
sleep stage 204 is indicative of a predetermined period of time during which the user falls into a deep sleep, increases a room temperature to a second temperature Ti+x higher than the setup temperature Ti atstep 306, maintains the second temperature Ti+x for a predetermined period of time atstep 308, and repeatedly increases or reduces the room temperature in a predetermined temperature range from the setup temperature Ti to the second temperature Ti+x atsteps sleep stage 204 continuously increases a room temperature during a predetermined period of t22∼t23, such that the room temperature reaches the second temperature Ti+x. As a result, the deep-sleep stage 204 prevents the user's skin temperature from being excessively lowered, resulting in the implementation of an energy saving effect. The time from the temperature t22 to the other temperature t23 is in the range from 3 hours to 5 hours. During the time of t23∼t24, the deep-sleep stage 204 constantly maintains the second temperature Ti+x. Thereafter, the reason why the deep-sleep stage 204 repeatedly increases or reduces the room temperature in a predetermined temperature range from the setup temperature Ti to the second temperature Ti+x is to prevent the user's skin temperature from being excessively increased or reduced. Furthermore, if the user's skin temperature reaches a normal or steady state, the deep-sleep stage 204 increases the room temperature to the second temperature Ti+x, resulting in the implementation of an energy saving effect. In the case of the standard execution time shown inFIG. 2 , the time of t23∼t24 is established in the range from a minimum of 1 hour to a maximum of 3 hours. A repetition time from the rising time of the room temperature to the drop time of the same is equal to or less than a total of 2 hours. - The wake-up
stage 206 increases a user's temperature to facilitate physiological actions of the user. In more detail, the wake-upstage 206 gradually increases the room temperature to a third temperature Ti+y higher than the second temperature Ti+x, and maintains the third temperature Ti+y for a predetermined period of time atstep 314. The time of t26∼t27 during which the wake-upstage 206 is executed is established in the range from a minimum of 30 minutes to a maximum of 2 hours. If the sleep mode setup time elapses during the wake-upstage 206 atstep 316, the wake-up mode is terminated. - In accordance with a preferred embodiment of the present invention, the user can directly enter a total execution time of the sleep mode using the
user input unit 104. For example, if the user determines the total execution time of the sleep mode to be 8 hours equal to the standard execution time, the sleep-entrance stage 202, the deep-sleep stage 204, and the wake-upstage 206 ofFIGS. 2∼3 are executed for individual predetermined times, respectively. In this case, the execution time of the sleep-entrance time 202 is established in the range of a minimum of 30 minutes to a maximum of 3 hours. The execution time of the wake-upstage 206 is in the range of 30 minutes to 2 hours. The deep-sleep stage 204 is located between the sleep-entrance stage 202 and the wake-upstage 206. - If the user determines a total execution time of the sleep mode to be a specific time (e.g., 4 hours) shorter than the standard execution time, the wake-up
stage 206 and some parts of the deep-sleep stage 204 are omitted. Otherwise, if the user determines a total execution time of the sleep mode to be a specific time (e.g., 12 hours) longer than the standard execution time, the deep-sleep stage 204 equal to the time of t23∼t26 is repeated during the above-mentioned time longer than the standard execution time. The above-mentioned respective preferred embodiments are shown inFIGS. 4∼7 . -
FIG. 4 is a graph illustrating temperature characteristics of a sleep mode for use in an air-conditioner in accordance with another preferred embodiment of the present invention.FIG. 5 is a flow chart illustrating a method for controlling a sleep mode of an air-conditioner according to sleep-mode temperature characteristics shown inFIG 4 in accordance with another preferred embodiment of the present invention. - As can be seen from
FIGS. 4∼5 , if a total execution time of the sleep mode is determined to be about 4 hours less than the standard execution time (i.e., 8 hours), a sleep-entrance time 402 is executed, and then only some parts of a deep-sleep stage 404 are executed for the remaining time other than the sleep-entrance time 402. - In other words, the air-conditioner performs the rapid cooling mode during a specific time of t40∼t41 of the sleep-
entrance stage 402 until a current temperature reaches a first temperature Ti-z less than the setup temperature Ti atstep 502. Thereafter, the air-conditioner maintains the first temperature Ti-z equal to the rapid cooling temperature during a specific time of t41 ∼ t42, such that the user's skin temperature is continuously reduced atstep 504. - The deep-
sleep stage 404 increases the room temperature to a second temperature Ti+x higher than the setup temperature Ti, and constantly maintains the second temperature Ti+x atsteps FIGS. 4∼5 , a total execution time of the sleep mode is short, such that the preferred embodiments cannot perform not only the wake-up stage but also the deep-sleep stage 404. Therefore, when the preferred embodiments perform the deep-sleep stage 404 during the remaining time of t42∼t44 after executing the sleep-entrance stage 402, it terminates the sleep mode if the sleep-mode setup time (e.g., 4 hours) elapses atstep 510. -
FIG. 6 is a graph illustrating temperature characteristics of a sleep mode for use in an air-conditioner in accordance with still another preferred embodiment of the present invention.FIG. 7 is a flow chart illustrating a method for controlling a sleep mode of an air-conditioner according to sleep-mode temperature characteristics shown inFIG. 6 in accordance with still another preferred embodiment of the present invention. - As can be seen from
FIGS. 6∼7 , if the user sets a total execution time of the sleep mode to about 12 hours, which is longer than the standard execution time, a specific time of t63∼t66 of the deep-sleep stage 604 is repeated during the time longer than the standard execution time. - In other words, the air-conditioner performs the rapid cooling mode during a specific time of t60∼t61 of the sleep-
entrance stage 602 until a current temperature reaches a first temperature Ti-z less than the setup temperature Ti atstep 702. Thereafter, the air-conditioner maintains the first temperature Ti-z equal to the rapid cooling temperature during a specific time of t61 □ t62, such that the user's skin temperature is continuously reduced atstep 704. - The deep-
sleep stage 604 increases the room temperature to a second temperature Ti+x higher than the setup temperature Ti atstep 706. The deep-sleep stage 604 maintains the room temperature equal to the second temperature Ti+x during a predetermined period of time atstep 708, and re-reduces the room temperature to the setup temperature Ti atstep 710. - A total execution time of the sleep mode selected by the user is longer than the standard execution time by 4 hours in the case of the preferred embodiments shown in
FIGS. 6 □7, such that the deep-sleep mode 604 is extended by 4 hours as compared to the deep-sleep stage of the standard execution time. As can be seen fromstep 608 ofFIG. 6 andsteps FIG 7 , the room temperature is repeatedly increased or reduced in the range from the setup temperature Ti to the second temperature Ti+x during the above-mentioned extended time, such that an optimum room temperature appropriate for the user's deep sleep is maintained. - The wake-up
stage 606 gradually increases the room temperature to the third temperature Ti+y higher than the second temperature Ti+x in the same manner as inFIGS. 2 □3, and then maintains the third temperature Ti+y during a predetermined period of time atstep 718. If all of the sleep mode setup time elapses while the wake-upstage 606 is executed atstep 720, the sleep mode is terminated. -
