       BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     The present invention relates to a unit type air conditioner, and more particularly, to a unit type air conditioner for fastening components more rigidly, for enhancing fastening strength.  
         [0004]     2. Background of the Related Art  
         [0005]     In general, the unit type air conditioner, having an indoor part and an outdoor part provided within one unit, is installed in a window or the like of a building for air conditioning a space in the building.  
         [0006]      FIG. 1  illustrates a perspective view of a related art unit type air conditioner, and  FIG. 2  illustrates a disassembled perspective view of a related art unit type air conditioner.  
         [0007]     Referring to  FIG. 1  and  2 , there is a base plate  10  in a bottom part of the air conditioner. The base plate  10 , rectangular substantially, has a barrier  12  projected from a center of an upper surface thereof.  
         [0008]     The barrier  12  divides the unit type air conditioner into an indoor part and an outdoor part. There is a frame form a front exterior of the air conditioner. The frame  14 , formed of a plastic, has an air inlet  15  in a front surface thereof. The air inlet  15  has an inlet grill  16  fitted thereto for passing air drawn therein, and an air filter  17  in rear of the inlet grill  16 .  
         [0009]     In the meantime, there is a discharge opening  15   a  in an upper part of the frame  14 , having a discharge grill  18  fitted thereto for passing air discharged from an inside of the air conditioner. The reference symbol  20  denotes a display part.  
         [0010]     There is a cabinet  22  forming exteriors of a rear part and side parts of the air conditioner. The cabinet  22  has a plurality of openings  23  for inlet/outlet of air. The cabinet  22  is mounted on the base plate  10  and the frame  14 .  
         [0011]     There is a cover  26  on the cabinet  22 , to form a top exterior of the outdoor part. The cover  26  has one end having a cover ledge  28  fastened to the frame  14 .  
         [0012]     An inside configuration of the unit type air conditioner divided into the indoor part and the outdoor part by the barrier  12  will be described.  
         [0013]     In the indoor part, there is an indoor heat exchanger  30  in rear of the frame  14 . The indoor heat exchanger  30  makes the air drawn from the room to heat exchange with a working fluid in a heat exchange cycle.  
         [0014]     The indoor heat exchanger  30  joins with an air guide  32  having an upper air guide  32   u  and a lower air guide  32   d , and an indoor fan (not shown) is mounted in the air guide  32 . The indoor fan makes the room air to circulate.  
         [0015]     There is a discharge guide  34  fitted to the upper part of the air guide  32  for guiding the air passed through the air guide  32  to the discharge opening  15   a . The discharge guide  34  is in communication with the discharge grill  18 .  
         [0016]     Next, in the outdoor part, there is a shroud  40  for guiding air flow formed by the outdoor fan  36 . The shroud  40  has a lower shroud  40   d  and an upper shroud  40   u , and has an opening  42  in a central part for mounting the outdoor fan  36  therein.  
         [0017]     The shroud  40  is fitted to an outdoor heat exchanger  44 . The outdoor heat exchanger  44  makes outdoor air drawn by the outdoor fan  36  to heat exchange with the working fluid in the heat exchange cycle. The reference symbol  46  denotes a compressor, a component of the heat exchange cycle.  
         [0018]     In the meantime, there is a curtain assembly  47  for blocking a gap between the unit type air conditioner and the window. The curtain assembly  47  has a curtain frame  48 , and a curtain  49 .  
         [0019]     However, the related art unit type air conditioner has the following problems.  
         [0020]     It is required that a space is maintained between the barrier and the shroud. This is because spaces are required for driving motors for the indoor fan and the outdoor fan respectively, the compressor, and pipelines for the working fluid. Moreover, spaces are required for introduction of the outdoor air drawn through opposite sides of the cabinet into the opening in the shroud.  
         [0021]     However, the barrier and the shroud, relatively high, have upper parts liable to move by an external force. The movements of the upper parts of the barrier and the shroud are liable to make interference with components around the barrier and the shroud, to cause damage to the components. For an example, if the shroud is fluid during transportation of the product, the outdoor fan and the outdoor heat exchanger interfere, resulting in damage to the outdoor fan and the outdoor heat exchanger.  
         [0022]     Moreover, the frame, the cabinet, and the cover are fastened together, and the cabinet is fastened to the base plate to form an exterior of the unit type air conditioner. However, the components forming the exterior, such as the frame, the cabinet, the cover, and the like, and the components on the base plate are not fastened. Therefore, if an external force is applied to the components of the exterior of the air conditioner, relative fluidity taken place between other components on the base plate and the components of the exterior damages the components. For an example, the projected opposite ends of the frame interfere with the indoor heat exchanger and the air guide, to damage the components.  
       SUMMARY OF THE INVENTION  
       [0023]     Accordingly, the present invention is directed to a unit type air conditioner that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
