Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an air conditioner, and more particularly to an air conditioner operation control apparatus and method thereof for detecting a shape of an inner space where an inner unit of air conditioner is disposed and a position where the inner unit is disposed to thereby enable the air conditioner to perform an appropriate cooling and heating operation according to the shape of the inner space and the position where the inner unit is installed. 
     2. Description of the Prior Art 
     Generally, an air conditioner is composed of a compressor, indoor heat exchanger and outdoor heat exchanger, through which refrigerant is circulated to thereby absorb heat (or warm air) and to discharge heat (or cold air) for performance of heating or cooling of a room. 
     The air conditioner thus described is generally so constructed as to have a predetermined capacity of heating and cooling, and once the air conditioner is installed at a predetermined position in a room for operation, the same detects temperatures in the room and operates heating or cooling according to the detected temperatures of the room. 
     FIG. 9 is a flow chart for illustrating an operational method of the conventional air conditioner for performing the heating or cooling according to the indoor temperatures. 
     According to step (S2) in FIG. 9, a user operates a remote controller (or key input unit) to establish a desired indoor temperature and thereby operate air conditioner. 
     At step (S4), a current indoor temperature is detected by a temperature detecting sensor. 
     At step (S6), a comparison is made between the indoor temperature and the temperature established by the user. 
     At step (S6) operation is distinguished between the heating and the cooling. In other words, the air conditioner is operated to perform cooling when the indoor temperature is higher than the established temperature as in step (S8), and the air conditioner is rendered inactivated to thereby stop cooling as in step (S10) when the indoor temperature is lower than the established temperature. 
     The air conditioner is activated to perform heating as in step (S8) when the indoor temperature is lower than the established temperature, and the air conditioner is rendered inactivated to stop heating as in step (S10) when the indoor temperature is higher than the established temperature. 
     At this time, cool air or hot air generated from the inner unit of the air conditioner is discharged to indoors by a fan, and the cool air or hot air flow is controlled in its discharged direction (hereinafter referred to as &#34;wind direction&#34;) by a vertical louver (up/down deflection louver) and a horizontal louver (left/right deflection louver). 
     For example, in Japanese Laid Open Patent Application No. Sho 62 (1987)-237242 entitled, &#34;Wind Direction Deflecting Method of Air Conditioner&#34;, a technique is disclosed to improve the conditions of a room by controlling an up/down defection louver and a left/right deflection louver according to indoor temperatures detected by a temperature detecting means. 
     In other words, the wind direction deflecting method of an air conditioner is disclosed wherein an up/down deflecting vane is driven in a horizontal direction and a left/right deflecting vane is driven to a position for directing air in a direction spaced by a maximum distance from an optimum quantity discharge direction established by an installed position of the air conditioner, when temperature detected by the temperature detecting means is in an established temperature region of &#34;A&#34; stored in an established temperature memory. Then, an up/down deflecting van is driven downward when a temperature detected by the temperature detecting means is in a temperature region of B (A≦B) stored in the established temperature memory means. Thereafter, a left/right deflecting vane is determined by the placement position of the air conditioner, and at the same time, the left/right deflecting vane is deflected to a position defining the optimum quantity discharge direction preset by the air conditioner during its installment, when temperature detected by the temperature detecting means is in an established temperature region of C (A≦B≦C) stored in the established temperature memory means. 
     Also, in a Japanese Laid Open Patent Application No. Hei 1 (1989)-147243 entitled &#34;An Air Conditioner&#34; which enables control of wind quantity, wind direction and discharged temperature of air by the user in order to provide pleasant air conditioning at all times without operation of a remote controller, in consideration of the influence of radiant heat and the like from a place where people are located, a wall surface or floor. A technique is disclosed wherein a detecting means is installed for detecting infrared rays of a room where the air conditioning is performed, and a temperature distribution of the room is detected by the detecting means, and thereafter the wind quantity, wind direction and discharged temperature of the air are controlled according to the detected temperature distribution. 
     However, even though the Japanese laid open patent application No. Sho 62-237242 has considerably contributed to the improvement of the living quarters, there are disadvantages in that the wind direction has to be established manually and the air conditioning cannot be accomplished according to forms or shapes of the living quarters. 
     Furthermore, even though the Japanese laid open patent application No. Hei 1-147243 has disclosed a technique of equally regulating the indoor temperature to thereby provide a pleasant atmosphere to the room, there are still problems in that the performance of air conditioning according to the shape or form of the room is impossible, and the discharge of air to an unnecessary part cannot be prevented, to thereby reduce the efficiency of the air conditioner. 
     SUMMARY OF THE INVENTION 
     Accordingly, the present invention is disclosed to solve the aforesaid problems and it is an object of the present invention to provide an effectively pleasant indoor space by detecting a shape of the room where an indoor unit of the air conditioner is installed and a position of the indoor unit relative to the room configuration to thereby allow the wind direction, wind direction angle and the wind quantity to be controlled according to the detected indoor shape and installed position of the indoor unit. 
     According to one aspect of the present invention, there is provided an air conditioner operation control apparatus comprising: an indoor shape detecting means for detecting the shape of the room for performing the air conditioning; a control means for establishing wind direction and/or wind direction angle control data according to the indoor space shape detected by the indoor shape detecting means; and a regulating means for regulating the wind direction and/or wind direction angle according to the control data established by the control means. 
     According to another aspect of the present invention, there is provided an air conditioner operation control method comprising: detecting the indoor shape for performing the air conditioning; establishing the wind direction and/or wind direction angle control data according to the detected indoor shape; and regulating the wind direction and/or wind direction angle according to the established control data.

     Hereinafter, the control apparatus and method of the air conditioner according to the present invention will be described in detail with reference to the accompanied drawings. 
     First Embodiment 
     In FIG. 3, step (S110) is a step for operating the air conditioner, wherein, when the user selects the desired indoor temperature and cooling or heating function by utilizing the remote controller (or key input unit), the remote controller transmits a signal, and the remote controller receiving unit 30 receives the signal. 
     The signal received at the remote controller receiving unit 30 is input to the control unit 40, which outputs a control signal to the compressor driving unit 50, fan driving unit 60, wind direction vane control unit 70 and the like according to the signal to thereby drive the air conditioner. 
     At this time, it should be apparent that the control unit 40 is operated according to the indoor temperature detected by the indoor temperature sensing unit 20. 
     Then, when the user selects at step (S112) an operating mode which requires that the air conditioner operate according to the indoor room shape (form), the control unit 40 drives the distance detecting unit 10 at step (S114) to thereby detect the room shape. 
     In other words, the control unit 40 during step (S114) drives the right side distance detecting sensor 12a in the distance detecting unit 10 to thereby measure a distance (l1) between the indoor unit and the right side wall, and the left side distance detecting sensor 12b is driven to measure a distance (l2) between the indoor unit and the left side wall, so that an indoor crosswise length (L1=l1+l2) which is to be covered by the air conditioning is determined. 
     Furthermore, the front side distance detecting sensor 14 is activated to measure a distance between the indoor unit and a front wall, so that a lengthwise distance L2 of the room is determined. 
     Step (S116) discriminates whether the measured crosswise length (L1) and lengthwise distance (L2) are equal. 
     As a result of the discrimination at step (S116), if the two lengths L1 and L2 are the same, the operational flow proceeds to step (S120). 
     A discrimination is made at step (S120) as to whether the lengthwise distance L2 is longer than a predetermined length. 
     As a result of the discrimination at step (S120), if the lengthwise distance L2 is longer than the predetermined length, flow proceeds to step (S122). 
     In other words, if it is determined at steps (S116) and (S120) that the indoor structure is a spacious (large) perfect square (FIG. 6a), step (S122) maintains the wind direction level at an average level and establishes a data for strengthening the wind speed, and outputs the control signal thereabout to the wind direction vane control unit 70 and the fan driving unit 60. 
     The air conditioner is operated at step (S160) according to the established data. 
     The wind direction vane control unit 70 drives a vertical flow adjustment vane 72 according to the established data to thereby cause the wind direction angle to maintain an average level, and the fan driving unit 60 is so controlled as to output strong wind speed for operation of the air conditioner. 
     Accordingly, as illustrated in the plan view according to FIG. 6a, the cool air or warm air maintains the wind direction angle and wind speed appropriate for a spacious square indoor structure and is discharged through the discharge port 104 of the indoor unit 100. 
     As a result of discrimination at step (S120), if the lengthwise length (L2) is shorter than the predetermined length, operational flow proceeds to step (S124) . 
     In other words, if steps (S116) and (S120) show that the indoor structure is a perfect square but not spacious (large) (FIG. 6b), a data is established at step (S124) for maintaining the wind direction angle at an average level and the wind speed at a weak level, and then a corresponding control signal is output to the wind direction vane control unit 70 and the fan driving unit 60. 
     The wind direction vane control unit 70 drives the vertical flow adjustment vane 72 according to the established data to thereby maintain the wind direction angle at an average level, and the fan driving unit 60 is so controlled as to output the wind speed at a weak level for operation of the air conditioner. 
     Accordingly, as illustrated in FIG. 6b, the cool air or warm air maintains a wind direction angle and wind speed appropriate for a perfect square and small indoor structure to thereafter be discharged to the discharge port 104 of the indoor unit 100. 
     Meanwhile, as a result of discrimination at step (S116), if the crosswise length (L1) and the lengthwise length (L2) are different, flow advances to step (S130). 
     A discrimination is made at step (S130) as to whether the lengthwise distance (L2) is longer than the crosswise length (L1). 
     As a result of discrimination at step (S130), if the lengthwise distance (L2) is longer than the predetermined length, flow advances to step (S142). 
     In other words, because the indoor structure is revealed to have a spacious non-square rectangular shape (FIG. 6c) having a longer lengthwise distance as a result of steps (S116), (S130) and (S140), a data is established at step (S142) for causing the wind direction angle to have an acute angle and the wind speed to be strong, and then a corresponding control signal is output to the wind direction vane control unit 70 and the fan driving unit 60. 
     At step (S160), the air conditioner is operated according to the data established at the aforesaid step. 
     In other words, the wind direction vane control unit 70 drives the vertical adjustment vane 72 according to the data established at the aforesaid step to thereby maintain the acute wind direction angle, and the fan driving unit 60 is so controlled to output the wind at high speed. 
     Accordingly, as illustrated in FIG. 6c, the cool air or warm air maintains the wind direction angle and the wind speed appropriate for a lengthy and spacious indoor structure to thereby be discharged through the discharge port 104 of the indoor unit 100. 
     As a result of discrimination at step (S140), if the lengthwise distance (L2) is shorter than the predetermined length, flow advances to step (S144). 
     In other words, because the indoor structure is revealed to have a small, non-square rectangular shape (FIG. 6a) as a result of steps (S116), (S130) and (S140), a data for an acute wind direction angle and weak wind speed is established at step (S144), and then a corresponding control signal is output to the wind direction vane control unit 70 and fan driving unit 60. 
     The air conditioner is operated at step (S160) according to the afore-established data. 
     In other words, the wind direction vane control unit 70 drives the vertical adjustment vane 72 according to the afore-established data to thereby produce a narrow wind direction angle and the fan driving unit 60 is so controlled as to output weak wind speed for operation of the air conditioner. 
     Accordingly, as illustrated in FIG. 6d, the cool or warm air maintains the wind direction angle and the wind speed appropriate for a lengthy and narrow indoor structure to thereafter be discharged through the discharge port 104 of the indoor unit 100. 
     As a result of step (S130), if the lengthwise distance (L2) is not longer than the crosswise length (L1), a discrimination is made at step (S150) as to whether the lengthwise distance (L2) is longer than the predetermined length. 
     As a result of step (S150), if the lengthwise distance (L2) is longer than the predetermined length, flow proceeds to step (S152). 
     In other words, because the indoor structure has a shape of a lengthy and spacious non-square crosswise rectangle (FIG. 6e) as revealed by steps (S116), (S130) and (S150), a data is established for broadening the wind direction angle and for strengthening the wind speed at step (S152), and then a corresponding control signal is output to the wind direction vane control unit 70 and the fan driving unit 60. 
     The air conditioner is operated at step (S160) according to the afore-established data. 
     In other words, the wind direction vane control unit 70 drives the vertical adjustment vane 72 according to the afore-established data to produce a broad wind direction angle, and the fan driving unit 60 is so controlled as to output strong wind speed for operation of the air conditioner. 
     Accordingly, as illustrated in FIG. 6e, the cool air or warm air maintains the wind direction angle and wind speed appropriate for an indoor space of lengthy and spacious area crosswise to thereby be discharged through the discharge port 104 of indoor unit 100. 
     As a result of discrimination at step (S150), if the lengthwise distance (L2) is shorter than the predetermined length, flow proceeds to step (S154). 
     In other words, because the indoor structure has a shape of a non-square, lengthy crosswise rectangle of not much space (FIG. 6f) as a result of steps (S116), (S130) and (S150), a data is established for a broad wind direction angle and a weak wind speed at step (S154), and then a corresponding control signal is output to the wind direction vane control unit 70 and the fan driving unit 60. 
     The air conditioner is operated at step (S160) according to the afore-established data. 
     In other words, the wind direction vane control unit 70 drives the vertical adjustment vane 72 according to the afore-established data to thereby produce a broad wind direction angle, and the fan driving unit 60 is so controlled to have a weak wind speed for operation of the air conditioner. 
     Accordingly, as illustrated in FIG. 6f, the cool air or warm air maintains the wind direction angle and wind speed appropriate for a crosswise lengthy but narrow indoor structure to there after be output through the discharge port 104 of the indoor unit 100. 
     As noted from the foregoing, according to the air conditioner operation control apparatus and method thereof, the wind direction angle and wind speed are maintained according to the indoor structure to thereby enable to provide a comfortable indoor space. 
     Second Embodiment 
     In FIG. 4, step (S210) is a step for activating the air conditioner, which is the same as the step (S110) already explained in the first embodiment. 
     When the user selects an operating mode which operates according to a position where the indoor unit 100 of the air conditioner is disposed, the control unit 40 drives the distance detecting unit 10 at step (S214) to thereby detect a position of the indoor unit 100. 
     In other words, the control unit 40 activates the right side distance detecting sensor 12a of the distance detecting unit 10 at step (S214) to measure a distance l1 (hereinafter to be referred to as &#34;a first distance&#34;) between the indoor unit an the right side wall, and activates the left side distance detecting sensor 12b to measure a distance l2 (hereinafter to be referred to as &#34;a second distance&#34;) between the indoor unit and the left side wall. 
     Furthermore, the lower side distance detecting sensor 16 is activated to thereby measure a disposed height l3 (hereinafter to be referred to as &#34;a third distance&#34;) between the indoor unit and the floor. 
     A discrimination is made at step (S216) as to whether the afore-mentioned first distance (l1) and the second distance (l2) are the same length. 
     As a result of the discrimination at step (S216), if the two distances are the same (FIG. 7a), flow advances to step (S220). 
     A discrimination is made at step (S220) as to whether the third distance (l3) is the same length as the predetermined length. If the two lengths are the same (FIG. 7d), flow proceeds to perform step (S222). 
     In other words, because the indoor unit 100 is disposed horizontally centrally and vertically centrally on the wall surface (FIGS. 7a, 7d) as discriminated by the afore-mentioned step, a data for maintaining a horizontally forward wind direction is established at step (S222), so that a corresponding control signal can be output to the wind direction vane control unit 70. 
     The air conditioner is operated at step (S270) according to the afore-established data. 
     In other words, the wind direction vane control unit 70 activates the vertical adjustment vane 72 and the horizontal flow adjustment vanes 74a and 74b according to the afore-established data to thereby cause the wind direction to be directed horizontally forwardly. 
     Accordingly, the cool air or warm air discharged from the discharge port 104 of the indoor unit 100, as illustrated in FIGS. 7a and 7d, is directed horizontally forwardly toward a center of the room. 
     As a result of discrimination at step (S220), if the third distance (l3) is not the same as the predetermined length, flow advances to step (S224). 
     A discrimination is performed at step (S224) as to whether the third distance (l3) is longer than the predetermined length. 
     As a result of discrimination at step (S224), if the third distance (l3) is longer than the predetermined length (FIG. 7e), flow advances to step (S226). 
     In other words, because the indoor unit 100 is disposed horizontally centrally but vertically nearer to the ceiling than to the floor (FIGS. 7a, 7e) as a result of step (S226), data is established at step (S226) for maintaining a forwardly downward wind direction, and a corresponding control signal is output to the wind direction vane control unit 70. 
     The air conditioner is operated at step (S270) according to the afore-established data. 
     In other words, the wind direction vane control unit 70 activates the vertical adjustment vane 72 and the horizontal adjustment vanes 74a and 74b according to the afore-established data to thereby cause the wind direction to be downwardly and forwardly. 
     Accordingly, the cool air or warm air discharged from the discharge port 104 of the indoor unit 100, as illustrated in FIGS. 7a and 7e, is directed toward the center of the room. 
     As a result of the discrimination at step (S224), if the third distance (l3) is not longer than the predetermined length (FIG. 7f), flow proceeds to step (S228) . 
     In other words, because the indoor unit 100 is disposed horizontally centrally but vertically nearer to the floor than to the ceiling (FIGS. 7a, 7f), a data is established at step (S228) for maintaining the wind direction forwardly upwardly, and a corresponding control signal is output to the wind direction vane control unit 70. 
     The air conditioner is operated at step (S270) according to the afore-established data. 
     In other words, the wind direction vane control unit 70 activates the vertical adjustment vane 72 and the horizontal adjustment vanes 74a and 74b according to the afore-established data to thereby cause the wind direction to travel forwardly and upwardly. 
     Accordingly, the cool or warm air discharged from the discharge port 104 of the indoor unit 100, as illustrated in FIGS. 7a and 7f, is directed toward the center area of the room. 
     As a result of step (S216), if the first distance (l1) and the second distance (l2) are not the same, flow advances to step (S230). 
     A discrimination is performed at step (S230) as to whether the second distance (l2) is longer than the first distance (l1). 
     As a result of discrimination at step (S230), if the second distance (l2) is longer than the first distance (l1) (FIG. 7b), flow proceeds to step (S240). 
     A discrimination is performed at step (S240) as to whether the third distance (l3) is the same as the predetermined distance. 
     As a result of discrimination at step (S240), if the third distance (l3) is the same as the predetermined distance (FIG. 7d), flow proceeds to step (S242). 
     In other words, because the indoor unit 100 is disposed vertically centrally, but horizontally to the right on the wall surface (FIG. 7b, 7d), a data is established at step (S242) for maintaining the wind horizontally leftwards, and then a corresponding control signal is output to the wind direction vane control unit 70. 
     The air conditioner is operated at step (S270) according to the afore-established data. 
     In other words, the wind direction vane control unit 70 activates the vertical adjustment vane 72 and the horizontal adjustment vanes 74a and 74b according to the afore-established data to thereby cause the wind direction to flow horizontally toward the left side of the room. 
     Accordingly, the cool or warm air discharged from the discharge port 104 of the indoor unit 100, as illustrated in FIGS. 7b and 7d, is directed toward the center of the room. 
     As a result of the discrimination at step (S240), if the third distance (l3) is not the same as the predetermined length, flow proceeds to step (S244).

     Third Embodiment 
     In FIG. 5, step (S310) is a step for activating the air conditioner, which is the same as step (S110) already described in the first embodiment. 
     When the user selects an operating mode which operates according to both the room shape and a position where the indoor unit 100 of the air conditioner is disposed, the control unit 40 activates the distance detecting unit 10 at step (S314) to thereby detect the indoor room shape and the position of the indoor unit 100. 
     In other words, the control unit 40 activates the right side distance detecting sensor 12a of the distance detecting unit at step (S314) to measure a distance l1 (hereinafter to be referred to as &#34;a first length&#34;) between the indoor unit and a right side wall, and then drives the left side distance detecting sensor 12b to measure a distance l2 (hereinafter referred to as &#34;a second length&#34;) between the indoor unit and the left side wall for calculation of a crosswise length (L1=l1+l2) of the room where the air conditioning is to be performed. 
     Furthermore, a front side distance detecting sensor 14 is activated to measure the distance between the indoor unit and a front side wall for calculation of a longitudinal length L2 of the room. 
     A discrimination is made at step (S316) as to whether the afore-measured crosswise length (L1) is longer than the longitudinal length (L2). 
     As a result of discrimination at step (S316), if the crosswise length (L1) is longer than the longitudinal length (L2), flow proceeds to step (S320). 
     A discrimination is performed at the step (S320) as to whether the first length (l1) measured at the step (S314) is the same as the second length (l2). 
     As a result of discrimination at step (S320), if the first length (l1) is the same as the second length (l2), flow advances to step (S322). 
     In other words, because the room where the air conditioning is to be performed has a shape of a long crosswise rectangle, and the indoor unit of the air conditioner is disposed at the center of the room (FIG. 8a), according to steps (S316) and (S320), a data is established at step (S322) for broadening the wind direction angle and directing the wind horizontally centrally toward the center of the room, and then a corresponding control signal is output to the wind direction vane control unit 70. 
     The air conditioner is operated at step (S360) according to the afore-established data. 
     In other words, the wind direction vane control unit 70 activates the horizontal adjustment vanes 74a and 74b according to the afore-established data to thereby cause the wind direction angle to broaden and the wind direction to be horizontally toward the center for operation of the air conditioner. 
     Accordingly, as illustrated in FIG. 8a, the cool or warm air maintains the wind direction angle and the wind direction appropriate for the shape of the room, to thereafter be discharged through the discharge port 104 of the indoor unit 100. 
     As a result of discrimination at step (S320), if the first length (l1) is not the same as the second length (l2), flow proceeds to step (S330). 
     As a result of discrimination at step (S330), if the first length (l1) is longer than the second length (l2), flow proceeds to step (S332). 
     In other words, because the room where the air conditioning is to be performed has a shape of a transversely long rectangle, and the indoor unit 100 of the air conditioner is disposed at a left side of the room (FIG. 8b) according to steps (S316), (S320) and (S330), data is established at step (S332) for broadening the wind direction angle and directing the wind toward the right side, and then a corresponding control signal is output to the wind direction vane control unit 70. 
     The air conditioner is operated at step (S360) according to the afore-established data. 
     In other words, the wind direction vane control unit 70 drives the horizontal flow adjustment vanes 74a and 74b according the afore-established data to thereby broaden the wind direction angle and to direct the wind toward the right side for operation of the air conditioner. 
     Accordingly, as illustrated in FIG. 8b, the cool air or warm maintains the wind direction angle and wind direction appropriate for the indoor structure to thereby be discharged to the discharge port 104 of the indoor unit 100. 
     As a result of discrimination at step (S330), if the first length (l1) is shorter than the second length (l2), flow proceeds to step (S334). 
     In other words, because the room where the air conditioning is to be performed has a shape of a transversely long rectangle, and the indoor unit 100 of the air conditioner is disposed at the right side of the room according to steps (S316), (S320) and (S330), data is established at the step (S334) for broadening the wind direction angle and directing the wind toward the left side, and then a corresponding control signal is output to the wind direction vane control unit 70. 
     The air conditioner is operated at step (S360) according to the afore-established data. 
     In other words, the wind direction vane control unit 70 drives the horizontal flow adjustment vanes 74a and 74b according to the afore-established data to thereby broaden the wind direction angle and to direct the wind toward the left side for operation of the air conditioner.

     A discrimination is made at step (S340) as to whether the first length (l1) and the second length (l2) measured at the step (S314) are equal. 
     As a result of discrimination at the step (S340), if the first length (l1) and the second length (l2) are the same, flow proceeds to step (S342). 
     In other words, because the room where the air conditioning is to be performed has the shape of a longitudinally long rectangle and the indoor unit 100 of the air conditioner is disposed at the center of the room according to the discrimination results at the steps (S316) and (S340), data is established at step (S342) for broadening the wind direction angle and directing the wind toward the center, and then, a corresponding control signal is output to the wind direction vane control unit 70. 
     The air conditioner is operated at step (S360) according to the afore-established data. 
     In other words, the wind direction vane control unit 70 drives the horizontal adjustment vanes 74a and 74b according to the afore-established data to cause the wind direction angle to be narrow and the wind direction to be directed toward the center for operation of the air conditioner. 
     Accordingly, as illustrated in FIG. 8d, the cool air or warm air maintains a wind direction angle and wind direction appropriate for the structure of the room to thereafter be discharged to the discharge port 104 of the indoor unit 100. 
     As a result of discrimination at the step (S340), if the first length (l1) is not the same as the second length (l2), flow proceeds to step (S350). 
     As a result of discrimination at the step (S350), if the first length (l1) is not the same as the second length (l2), flow proceeds to step (S352). 
     In other words, because the room where the air conditioning is to be performed has a shape of a longitudinally long rectangle and the indoor unit 100 of the air conditioner is disposed at the left side according to the discrimination results at the steps (S316), (S340) and (S350), data is established at the step (S352) for narrowing the wind direction angle and directing the wind toward the right side, and then, an corresponding control signal is output to the wind direction vane control unit 70. 
     The air conditioner is operated at step (S360) according to the afore-established data. 
     In other words, the wind direction vane control unit 70 drives the horizontal adjustment vanes 74a and 74b according to the afore-established data to thereby narrow the wind direction angle and direct the wind toward the right side for operation of the air conditioner. 
     Accordingly, as illustrated in FIG. 8c, the cool or warm air maintains a wind direction angle and wind direction appropriate for the structure of the room to thereafter be discharged to the discharge port 104 of the indoor unit 100. 
     As a result of discrimination at the step (S350), if the first length (l1) is shorter than the second length (l2), flow proceeds to step (S354). 
     In other words, because the room where the air conditioning is to be performed has a shape of a longitudinally long rectangle, and the indoor unit 100 of the air conditioner is disposed at the right side of the room according to the discrimination results at the steps (S316), (S340) and (S350), data is established at the step (S354) for narrowing the wind direction angle and directing the wind toward the left side, and then, a corresponding control signal is output to the wind direction vane control unit 70. 
     The air conditioner is operated at step (S360) according to the afore-established data. 
     In other words, the wind direction vane control unit 70 drives the horizontal adjustment vanes 74a and 74b according to the afore-established data to thereby narrow the wind direction angle and to direct the wind toward the left side for operation of the air conditioner. 
     Accordingly, as illustrated in FIG. 8f, the cool or warm air maintains a wind direction angle and wind direction appropriate for the structure of the room to thereafter be discharged to the discharge port 104 of the indoor unit 100. 
     As seen from the foregoing description, the air conditioner operation control apparatus and method thereof, the wind direction angle and the wind direction are set in accordance with the shape of the room and position of the indoor unit, to thereby provide a delightful optimum room temperature. 
     Meanwhile, although the position of the indoor unit has been detected only by the left side and right side distance detecting sensors 12a and 12b in the third embodiment, it should be apparent that the height thereof can be measured by the lower side distance detecting sensor 16 to control the wind direction. 
     Furthermore, the control of the wind speed has not been described in the foregoing but it should be apparent that the wind speed can be controlled by the afore-detected shape of the room and the distance to the front detected by the front side distance detecting sensor 14. 
     As apparent from the above description, the air conditioner operation control apparatus and the method thereof according to the invention detects automatically the position of the indoor unit of the air conditioner, and provides a signal which controls the wind direction angle, wind direction, and wind speed to thereby provide maximized operational efficiency and comfortable indoor space. 
     Although the preferred embodiments of the invention have been disclosed for illustrative purposes, various modifications and changes are possible without departing from the scope and spirit of the present invention. 
     Although the above description has explained the structure of the room, wind direction angle, wind direction and wind speed in detailed examples it should also be apparent that the air conditioner can be controlled by more itemized examples. 
     Furthermore, the present invention has described in detail the distance detecting sensors but the number of the sensors can generally be increased or decreased. 
     It should be noted that the present invention is not limited by the preferred embodiments and the flow charts can be provided in various ways.
