     BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to an air conditioner. Although the present invention is suitable for a wide scope of applications, it is particularly suitable for smoothing a flow of air that is sucked or blown.  
      2. Discussion of the Related Art  
      Generally, an air conditioner, which includes a compressor and a heat exchanger to make a refrigerant flow therein, cools down or heats an indoor space such as a living room, a restaurant, a library, an office and the like. And, the air conditioner can be categorized into a separate type and a combined type.  
      The separate type air conditioner consists of an indoor unit having a heat exchanger for cooling or heating an indoor space, an outdoor unit having a built-in heat exchanger for heat exchange with an outdoor air, and a refrigerant pipe connecting the indoor unit to the outdoor unit.  
      The indoor and outdoor units of the separate type air conditioner are separately installed at indoor and outdoor spaces, respectively.  
      Meanwhile, the combined type air conditioner, which includes indoor and outdoor units built in one body together, is directly installed on a hole of a house wall or is hung on a window.  
      An air conditioner according to a related art is explained with reference to  FIG. 1  and  FIG. 2  as follows.  
      The air conditioner according to the related art shown in  FIG. 1  and  FIG. 2  is the combined type air conditioner having an indoor unit for a heat exchange with an indoor air and an outdoor unit for a heat exchange with an outdoor air, in which the indoor and outdoor units are built in one body.  
      Referring to  FIG. 1  and  FIG. 2 , the air conditioner consists of a base panel  2  forming an exterior, a frame  4  provided over the base panel  2 , an air guide  6  partitioning the base panel  2  and the frame  4  into an indoor part I and an outdoor part, a front panel  9  provided to a front side of the cabinet  4  toward an indoor space to configure a front part of the combined type air conditioner, and a compressor  12  changing a low-temperature low-pressure gaseous refrigerant into a high-temperature high-pressure refrigerant.  
      In the outdoor part, a condenser  14  radiating heat to air flowing within the outdoor part and an expansion valve (not shown in the drawing) expanding the refrigerant condensed by the condenser  14  are received.  
      To the indoor part I provided is an evaporator  16  evaporating the refrigerant expanded in the expansion valve. In doing so, the refrigerant absorbs heat of the air flowing within the indoor part to evaporate into a gaseous phase.  
      Meanwhile, outdoor intake ports  5  are formed at lateral and upper sides of the outdoor part to suck the outdoor air. A backside of the outdoor part is open to blow the air to the outdoor space.  
      An indoor air intake port  10  is provided to a lower part of a front side of the front panel  9 . And, an indoor air blowing port  11  is provided to an upper part of the front panel  9  to blow the air into the indoor space.  
      The air guide  6  consists of a vertical guide  7  provided vertical to a topside of the base panel  2  and a horizontal guide  8  horizontally provided over the vertical guide  32  to guide the air forcibly moved by a turbo fan  24  to the indoor air blowing port  11 .  
      A bi-shaft motor  22  is provided to the air guide  6  of the combined type air conditioner. In this case, front and rear shafts  20   a  and  20   b  are projected from the bi-shaft motor  22  toward the indoor and outdoor parts, respectively.  
      The turbo fan  24  is connected to the front shaft  20   a  to forcibly circulate the indoor air to the evaporator  16 . And, an orifice accelerating a wind speed is provided to an intake side of the turbo fan  24 .  
      A propeller fan  28  is connected to the rear shaft  20   b  of the bi-shaft motor  20  to forcibly move the outdoor air toward the condenser  14 . And, a shroud  30  forming an air passage is provided in rear of the propeller fan  26 .  
      An operation of the above-configured related art combined type air conditioner is explained as follows.  
      First of all, once the combined type air conditioner is actuated, the refrigerant is circulated by the driven compressor  12  via the condenser  14 , the expansion mechanism (not shown in the drawing) and the evaporator  16 . And, the bi-shaft motor  20  rotates the turbo fan  24  and the propeller fan  28  to suck the indoor air and the outdoor air into the indoor part and the outdoor part, respectively.  
      In particular, the indoor air in front of the front panel  9  passes through the indoor air intake port  10  by the rotation of the turbo fan  24  and is then cooled down via the evaporator  16 .  
      A flowing direction of the air cooled down by the evaporator  16  is diverted along the orifice  26 , the vertical guide  7  and the horizontal guide  8  toward the indoor air blowing port  11  provided to the front panel  9  and is then blown to a front side of the front panel  9  via the indoor air blowing port  11 .  
      The air in the outdoor space is sucked into the outdoor intake ports  5  by the rotation of the propeller fan  28 , passes through the shroud  30 , passes through the condenser  14  to take heat from the refrigerant flowing within the condenser  14 , and is then blown out to the outdoor space.  
      However, the related art air conditioner has the following problems or disadvantages.  
      First of all, since the indoor air intake port and the indoor air blowing port are provided to the upper and lower parts of the front panel, respectively, a considerable quantity of the air blown into the indoor space is re-sucked into the indoor air intake port right after having been blown.  
      Secondly, since the flowing direction of the air flowing within the indoor part by the turbo fan is abruptly diverted by the horizontal guide, a flowing loss is considerable and a corresponding noise becomes a serious problem.  
      Thirdly, since the air is blown in the rear direction via the backside of the outdoor part, airflow resistance is raised to degrade the heat exchange performance of the outdoor part in case of an adverse wind.  
     SUMMARY OF THE INVENTION  
      Accordingly, the present invention is directed to an air conditioner that substantially obviates one or more problems due to limitations and disadvantages of the related art.

     DETAILED DESCRIPTION OF THE INVENTION  
      Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.  
      Referring to FIGS.  3  to  6 , an air conditioner according to a first embodiment of the present invention includes a cabinet enclosing various component parts for cooling/heating of an indoor space.  
      In the embodiment of the present invention, the cabinet preferably includes an indoor cabinet for a heat exchange with an indoor air and an outdoor cabinet for a heat exchange with an outdoor air.  
      In this case, the indoor air A is sucked via lateral sides of the indoor cabinet and the air-conditioned air within the cabinet is blown in a front direction of the cabinet.  
      And, the outdoor air B is sucked via lateral sides of the outdoor cabinet, exchanges heat, and is then blown in a rear direction.  
      Preferably, the cabinet has a fully open backside or has a substantially rectangular box shape having an opening at its backside. Yet, the cabinet can be variously configured.  
      For instance, the cabinet of the air condition according to the first embodiment of the present invention includes a base panel  52  forming a bottom of the cabinet, an indoor frame  55  having an indoor air intake port via which the indoor air is sucked, and an outdoor frame  64  provided over a rear part of the base panel  52 .  
      For example, the base panel  52 , the indoor frame  55  and the outdoor frame  64  can be built in one body. Preferably, the base panel  52 , the indoor frame  55  and the outdoor frame  64  are individually provided to be assembled in one body together for the sake of repair or cleaning of internal parts.  
      The indoor air intake port is provided to the cabinet, and more particularly, to at least on of right, left and upper sides of the indoor frame  55  to allow the indoor air to be sucked in lateral directions of the indoor frame  55 .  
      In the first embodiment of the present invention, at least one or more indoor air intake ports  53  and  54  are provided to the right and left sides of the indoor frame  55 .  
      For reference, the indoor air intake port provided to the right side of the indoor frame  55  is called a right indoor air intake port  53  and the indoor air intake port provided to the left side of the indoor frame  55  is called a left indoor air intake port  54 .  
      An indoor blower  72  is provided within the cabinet, and more particularly, within the indoor cabinet. And, an air guide  57  is provided in front of the indoor blower  72 .  
      Moreover, an orifice  56  is provided to the air guide  57  to allow the air, which is blown in a front direction by the indoor blower  72 , to pass through. In this case, the air guide  57  is preferably built in one body of the cabinet, and more particularly, in one body of the indoor frame  55 .  
      The cabinet further includes a front panel  53  configuring a front side of the cabinet. And, a blowing grill  59   a  having a plurality of ventilating openings is loaded on an indoor air blowing port  58 .  
      In this case, the front panel  59  is provided in front of the indoor blower  72 . Since the indoor air blowing port  58  is formed at the front panel  53 , the air-conditioned air is blown in the front direction of the cabinet by the indoor blower  72 .  
      Hence, the air guide  57  is provided between the indoor blower  72  and the indoor air blowing port  58  of the front panel  59 .  
      Meanwhile, a barrier  60  is provided within the cabinet. And, the cabinet is partitioned into the indoor cabinet and the outdoor cabinet by the barrier  60 .  
      In the present embodiment, to allow the indoor cabinet to include the indoor frame  55  and to allow the outdoor cabinet to include the outdoor frame  64 , it is preferable that the barrier  60  is provided to a rear end of the indoor frame  55  to partition the internal space of the cabinet.  
      Accordingly, the internal space of the cabinet is partitioned into an indoor side space I in which heat exchange with the indoor air is performed and an outdoor space O in which heat exchange with the outdoor air is performed.  
      Meanwhile, an outdoor air intake port is provided to at least one of left, right and upper sides of the outdoor cabinet to suck the outdoor air.  
      In the present embodiment, the outdoor air intake ports  61 ,  62  and  63  are provided to the left, right and upper sides of the outdoor frame  64 , respectively and the air is blown out via a backside of the outdoor frame  64 .  
      The outdoor air intake port provided to the right side of the outdoor frame  64  is named a right outdoor air intake port  61 , the outdoor air intake port provided to the left side of the outdoor frame  64  is named a left outdoor air intake port  62 , and the outdoor air intake port provided to the upper side of the outdoor frame  64  is named an upper outdoor air intake port  61 .  
      Hence, the outdoor air is sucked via the three sides of the outdoor frame  64  and the air is blown in a rear direction via the backside of the outdoor frame  64 .  
      Meanwhile, the indoor blower  72  is provided within the indoor cabinet forming the indoor side space and an outdoor blower  76  is provided within the outdoor cabinet forming the outdoor side space.  
      To drive the indoor blower  72 , a blower motor  70  is provided within the cabinet.  
      The indoor blower  72  includes an indoor blower fan that is connected to the blower motor  70 .  
      The outdoor blower  76  includes an outdoor blower fan.  
      In the present embodiment, the blower motor  70  is configured to drive both of the indoor blower  72  and the outdoor blower  76  simultaneously.  
      For this, the blower motor  70  is provided to the barrier  60 . Preferably, the lower motor  70  is a bi-shaft motor including a first rotational shaft  67  projected in a front direction toward the front panel  59  and a second rotational shaft  68  projected in a rear direction toward the backside of the outdoor frame.  
      The indoor blower fan having a front-to-rear shaft direction is connected to the first rotational shaft  67  of the bi-shaft motor to blow the air forward.  
      In particular, as the indoor blower fan rotates, the indoor air is sucked via the left and right indoor air intake ports  53  and  54  of the indoor frame  55  so that the indoor blower fan blows the air in the front direction toward the indoor air blowing port  58 .  
      In this case, the indoor blower fan includes a hub  73  connected to the first rotational shaft  67  of the bi-shaft motor and a plurality of spiral blades  74  provided to an outer circumference of the hub  73 . The above-configured blower fan is so-called an X-fan.  
      The outdoor blower fan having a front-to-rear shaft direction is connected to the second rotational shaft  68  of the bi-shaft motor to blow the air backward.  
      In particular, the outdoor blower fan sucks the air via the outdoor air intake ports  60 ,  61  and  62  to blow in the rear direction.  
      In this case, the outdoor blower fan preferably includes an X-fan having a hub  77  connected to the second rotational shaft  68  of the bi-shaft motor and a plurality of spiral blades  78  provided to an outer circumference of the hub  77 . Yet, the blower fan is not limited to the X-fan but can include different fans.  
      Meanwhile, at least one indoor heat exchanger  80  is provided within the indoor frame  55 , and more particularly, next to the indoor blower  72  to cool down or heat the indoor air.  
      In this case, the at least one indoor heat exchanger  80  is provided between the indoor blower  72  and the indoor air intake port to minimize a front-to-rear length of the cabinet.  
      In the present embodiment, a right indoor heat exchanger  81  is provided between the right indoor air intake port  53  and the indoor blower  72  and a left indoor heat exchanger  83  is provided between the left indoor air intake port  54  and the indoor blower  72 . Namely, the right indoor heat exchanger  81  is provided next to the right indoor air intake port  53  and the left indoor heat exchanger  83  is provided next to the left indoor air intake port  54 .  
      Hence, the air sucked via the right indoor air intake port  53  makes a heat exchange with the refrigerant flowing within the right indoor heat exchanger  81  and the air sucked via the left indoor air intake port  54  makes a heat exchange with the refrigerant flowing within the right indoor heat exchanger  83 .  
      Refrigerant inlet pipes  81   a  and  83   a  are connected to refrigerant inlet sides of the right and left indoor heat exchangers  81  and  83  in parallel, respectively. And, refrigerant outlet pipes  81   b  and  83   b  are connected to refrigerant outlet sides of the right and left indoor heat exchangers  81  and  83  in parallel, respectively.  
      Alternatively, the right indoor heat exchanger  81  and the left indoor heat exchanger  83  can be arranged parallel to either the eight or left side of the indoor frame  55 . Alternatively, the right indoor heat exchanger  81  and the left indoor heat exchanger  83  can be arranged to have prescribed angles from the right and left sides of the indoor frame  55 , respectively.  
      In case that the right indoor heat exchanger  81  and the left indoor heat exchanger  83  are arranged to have the prescribed angles from the right and left sides of the indoor frame  55 , respectively, heat transfer areas can be increased.  
      And, the right indoor heat exchanger  81  and the left indoor heat exchanger  83  vertically meet the air, which is sucked in lateral directions of the indoor cabinet to flow forward. Accordingly, in case of employing a general heat exchanger structure, passage resistance is minimized and heat transfer efficiency is enhanced.  
      Meanwhile, a shroud  86  is provided within the outdoor frame  64  to form a passage of the outdoor air moved by the outdoor blower  76 .  
      An orifice is formed in the shroud  86  to be provided to an outer circumference o the outdoor blower  76 .  
      At least one outdoor heat exchanger  90 , in which a refrigerant exchanging heat with the air blown backward by the outdoor blower  76  flows, is provided in rear of the shroud  86 .  
      And, the outdoor heat exchanger  90  is arranged long in right-to-left direction in a backside of the outdoor frame  64 .  
      A reference number ‘ 94 ’ indicates a compressor loaded on the base panel  52  to be located in the outdoor side space O. The compressor  94  is preferably installed in the vicinity of one of the outdoor air intake ports.  
      A reference number ‘ 96 ’ indicates a capillary tube connecting the outdoor heat exchanger  90  and the indoor heat exchanger  80  together to expand the refrigerant.  
      An operation of the above-configured air conditioner according to the first embodiment of the present invention is explained as follows.  
      First of all, once the air conditioner is actuated, the refrigerant is circulated by the driven compressor  94  and the indoor air and the outdoor air are sucked into the indoor cabinet and the outdoor cabinet by the driven blower motor  70 , respectively.  
      Once the blower motor  70  is driven, the indoor blower  72  is rotated to suck the indoor air via the right and left indoor air intake ports  53  and  54  of the indoor frame  55 .  
      The air sucked via the right and left indoor air intake ports  53  and  54  passes through the right and left indoor heat exchangers  81  and  83  to be cooled down or heated and is then blown forward by the indoor blower  72 .  
      The air blown by the indoor blower  72  passes through the orifice  56  and the indoor air blowing port  58  of the front panel  59  in turn and is then blown to a front side of the cabinet to cool down or heat the indoor space.  
      Meanwhile, once the outdoor blower  76  is rotated by the driven blower motor  70 , the outdoor air B is sucked in three directions via the outdoor air intake ports  61 ,  62  and  63  of the outdoor frame.  
      The air sucked into the outdoor cabinet via the outdoor air intake ports  61 ,  62  and  63  is blown backward by the outdoor blower  76 .  
      The outdoor air blown by the outdoor blower  76  exchanges heat with the outdoor heat exchanger  90  to be heated or cooled down and is then blown backward via the backside of the outdoor frame  64 .  
      An air conditioner according to a second embodiment of the present invention is explained with reference to FIGS.  7  to  9  as follows.  
      First of all, an air conditioner according to a second embodiment of the present invention includes the same elements of the air conditioner according the first embodiment of the present invention.

And, the operational principle of the first embodiment of the present invention is like that of the second embodiment of the present invention, of which explanation is skipped. And, the same reference numbers will be used throughout the drawings to refer to the same or like parts.  
      An air conditioner according to a third embodiment of the present invention is explained with reference to  FIG. 10  as follows.  
      In explaining an indoor unit of an air conditioner according to a third embodiment of the present invention, the elements and its operational principle are like those of the first embodiment of the present invention except at least one outdoor heat exchanger provided within the outdoor cabinet.
