Best Mode for Carrying out the Invention

[0011] The details of one or more embodiments are set forth in the accompanying drawings and the description below. Other features will be apparent from the description and drawings, and from the claims.

[0012] Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings.

[0013] Fig. 2 is a block diagram of an air conditioner according to an embodiment and Fig. 3 is a view illustrating air-conditioning sections according to an embodiment.

[0014] Referring first to Fig. 2, an air conditioner includes an air-conditioning unit 10, an input unit 20, a wind direction adjusting unit 30, a location detecting unit 40, and a control unit 50. The air-conditioning unit functions to control indoor air. The input unit 20 receives manipulation signals of the air-conditioning unit 10 and the wind direction adjusting unit 30 adjusts directions of cool winds and hot winds generated from the air conditioning-unit 10. The location detecting unit 40 detects a location of a user (i.e., a learner) located in the indoor space. In addition, the control unit 50 controls the air-conditioning unit 10 and the wind adjusting unit 30 according to the signals input to the input unit 20 and the learner's location detected by the location detecting unit 40.

[0015] In more detail, the air-conditioning unit 10 includes a variety of components for controlling the indoor air, i.e., generating the cool and hot winds. That is, the air-conditioning unit 10 includes components constituting a heat exchange cycle, such as a compressor, a condenser, an expansion unit, and an evaporating unit. The air-conditioning unit 10 includes an indoor unit and an outdoor unit, which may be separately provided or integrated with each other.

[0016] The input unit 20 receives a manipulation signal for setting cooling and heating temperatures and a manipulation signal for an amount of cool and hot winds. Particularly, the input unit 20 receives input air-conditioning temperatures such as an input cooling temperature and an input heating temperature.

[0017] The wind direction adjusting unit 30 includes a vertical adjusting unit 31 and a horizontal adjusting unit 33. The vertical adjusting unit 31 adjusts a vertical direction of the cool and hot winds generated from the air-conditioning unit 10. Further, the horizontal adjusting unit 33 adjusts a horizontal direction of the cool and hot winds. For example, veins may be used as the vertical adjusting unit 31 and the louvers may be used as the horizontal adjusting unit 33.

[0018] The location detecting unit 40 may be installed at, for example, a side of the air-conditioning unit 10. Accordingly, when the air-conditioning unit 10 includes the indoor and outdoor units, the location detecting unit 40 may be installed in the indoor unit. Needless to say, the location detecting unit 40 may be installed at other places rather than the air-conditioning unit 10. An infrared sensor may be used as the location detecting unit 40.

[0019] In this embodiment, the location detecting unit 40 determines if the user is located in one of air-conditioning sections Z1 to Z9 that are defined by dividing the indoor space in accordance with a distance from the air-conditioning unit 10 and an angle with respect to the air-conditioning unit 10. Referring to Fig. 3, the air-conditioning sections Z1 to Z9 are defined by dividing the indoor space along a plurality of imaginary latitude lines that are spaced apart from each other by predetermined radii from a center of the air-conditioning unit 10 and extend in a circumferential direction and longitudinal lines extending in a radial direction and spaced apart from each other by predetermined central angles with respect to the center of the air-conditioning unit 10. In Fig. 3, the indoor space is divided into nine air-conditioning sections Z1 to Z9. However, the present invention is not limited to this.

[0020] Meanwhile, the control unit 50 controls such that the air-conditioning unit 10 cools or heats the indoor space in response to the input cooling and heat temperatures input to the input unit 20. Especially, the control unit 50 determines if the user exists in the indoor space, i.e., in one of the air-conditioning sections Z1 to Z9 in accordance with the user's location detected by the location detecting unit 40. The control unit 50 adjusts the cooling and hot winds as direct or indirect winds in accordance with whether the user exists in one of the air-conditioning sections Z1 to Z9. In addition, the control unit 50 corrects the input cooling and heating temperatures when the user exists in one of the air-conditioning sections Z1 to Z9 for a predetermined time or more.

[0021] That is, when it is determined that the user exists in the indoor space, the control unit 50 controls the wind direction adjusting unit 30 such that the direct wind having the input cooling or heating temperature can be directly directed to one of the air-conditioning sections Z1 to Z9 where the user is detected by the location detecting unit 40. However, when it is determined that the user does not exist in the indoor space, the control unit 40 controls the wind direction adjusting unit 30 such that the indirect wind having the input cooling and heating temperatures can be indirectly directed toward at least three of the air-conditioning sections Z1 to Z9.

[0022] In addition, when it is detected that the user exits in one of the air-conditioning sections Z1 to Z9 for the predetermined time or more, the control unit 50 corrects the input cooling and heating temperatures into preset corrected cooling and heating temperatures. Further, the control unit 50 controls the wind direction adjusting unit 30 such that the hot wind having the corrected heating temperature or the cool wind having the corrected heating temperature is directed toward at least three of the air-conditioning sections Z1 to Z9 as the indirect wind. At this point, the corrected cooling - temperature is set to be higher than the input cooling temperature by 2°C and the corrected heating temperature is set to be lower than the input heating temperature by 2°C.

[0023] The following will describe a method for controlling the air condition according to an embodiment in more detail.

[0024] Fig. 4 is a flowchart illustrating an air-conditioning process by an air conditioner controlling method of an embodiment. Fig. 4 illustrates a cooling mode case. However, the present invention can be identically applied to a heat mode case.

[0025] Referring to Fig. 4, the input cooling temperature is first input to the input the unit 20 (S11). Needless to say, other manipulation signals such as a wind volume may be further input to the input unit 20.

[0026] The air-conditioning unit 10 starts the air-conditioning with the input cooling temperature input to the input unit 20 (S13). That is, the air-conditioning unit 10 generates a cool wind having the input cooling temperature and sends the cool wind to the indoor space.

[0027] Next, the location detecting unit 40 detects if the user is located in the indoor space (S 15). In more detail, the location detecting unit 40 detects if the user exists in one of the air-conditioning sections Z1 to Z9.

[0028] Meanwhile, the control unit 50 determines if the user exists in one of the air-conditioning sections Z1 and Z9 or not in accordance with the user's location detected by the location detecting unit 40 (S 17). The control unit controls the cool wind generated by the air-conditioning unit 10 as the direct or indirect wind in accordance with the existence of the user in one of the air-conditioning sections Z1 to Z9 or corrects the input cooling temperature into the preset corrected cooling temperature.

[0029] In more detail, when it is determined that the user exists in one of the air-conditioning sections Z1 to Z9, the control unit 50 controls the wind direction adjusting unit 30 such that the cool wind having the input cooling temperature and generated from the air-conditioning unit 10 is directly directed to one of the air-conditioning sections Z1 to Z9 where the user exits (S 19). Therefore, the user existing in one of the air-conditioning sections Z1 to Z9 can feel the more comfort.

[0030] Next, the control unit 50 determines if the air-conditioning is finished (S21). It can be determined whether the air-conditioning is finished in accordance with the finish of the air-conditioning time that is set by a manipulation signal input to the input unit 20 or whether a manipulation signal for finishing the air-conditioning is put by the user. When it is determined that the air-conditioning is not finished, Step 15 and the followings are performed.

[0031] Meanwhile, when it is determined in Step 17 that the user does not exist in one of the air-conditioning sections Z1 to Z9, the control unit 50 controls the wind direction adjusting unit 30 such that the cool wind having the input cooling temperature and generated by the air-conditioning unit 10 is formed in the indirect wind directing toward at least three of the air-conditioning sections Z1 to Z9 (S23). At this point, the control unit 50 may control the wind direction adjusting unit 30 such that the indirect wind is directed to substantially all of the air-conditioning sections Z1 to Z9.

[0032] Further, in a state where the cooling mode is realized by the indirect wind

in Step 23, the location detecting unit 40 detects the user's location (S25). In addition, the control unit 50 determines if the user exists in the indoor space in accordance with the user's location detected by the location detecting unit 40 S27.

[0033] When it is determined that the user exits in the indoor space, the control unit 50, Step 19 and the following steps are performed. However, when it is determined that the user does not exist in the indoor space, the control unit determines if a preset detection time has elapsed (S29). When it is determined that the preset detection time has elapsed, the control unit 50 corrects the input cooling temperature into the preset corrected cooling temperature and controls the wind direction adjusting unit 30 such that the air-conditioning sections Z1 to Z9 are cooled according to the preset corrected cooling temperature (S31). However, when it is determined that the preset detection time has not elapsed, Step 23 and the following steps are preformed.

[0034] Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be revised by those skilled in the art that will fall within the scope of the appended claims. More particularly, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, alternative uses will also be apparent to those skilled in the art.

Industrial Applicability

[0035] According to the above-described air conditioner and method for controlling the same of the embodiments, the following effects can be expected.

[0036] The cool and hot winds generated by the air-conditioning unit are formed in the direct or indirect wind in accordance with whether the user exists in the indoor space. Therefore, the user's comfort can be enhanced.

[0037] Further, the input cooling or heating temperature is corrected when it is detected that the user does not exist in the indoor space for the preset time. Therefore, when the user does not exist in the indoor space, the cooling or heating load can be substantially reduced and thus the cooling and heating can be more economically realized.
