   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to dryers, and more particularly, to an exhaust dryer in which an exhaust pipe assembly thereof is modified for enhancing convenience of use and product reliability. 
   2. Discussion of the Related Art 
   In general, the laundry dryer blows hot air from a heater to a drum for evaporating moisture from laundry, to dry the laundry. In the laundry dryers, there are exhaust type dryers, and condensing type dryers depending on methods for processing moist air evaporated from the laundry. 
   The exhaust type dryer draws external air, heats the air with the heater, dries the laundry with heat air, and discharges moist air from the laundry to an outside of the dryer. The condensing type dryer condenses the moist air from the laundry, and reheats the air for drying the laundry. 
     FIG. 1  illustrates a side view of a related art exhaust type dryer having an exhaust pipe assembly mounted thereto. 
   Referring to  FIG. 1 , the related art dryer is provided with a body  10  which forms an exterior of a whole dryer, having an exhaust hole  11  for discharging exhaust air, and an exhaust pipe assembly  12  connected to the exhaust hole  11  for guiding the exhaust air to an outside of room. 
   Though not shown, the dryer is provided with a drum in the body for holding the laundry, the heater, and a fan unit. 
   The dryer draws external air, heats the air with the heater, supplies hot air to the laundry by means of the fan unit. The laundry is dried by the hot air, and moist air produced in this time is discharged to an outside of the dryer as an exhaust air. 
   The exhaust air is discharged to an outside of room through the exhaust pipe assembly. 
   The exhaust pipe assembly  12  is provided with a bellows pipe  13  fastened to an outside circumference of the exhaust hole  11  with a clamp or the like, and extended to an outside of room for discharging the exhaust air to an outside of room, and a hood exhaust pipe  20  connected to the bellows pipe so as to be projected to the outside of room. 
   The bellows pipe  13  may have a plurality of pipes attached together with adhesive tapes as required, or instead of the bellows pipe, a long piece of straight pipe may also be used. 
   However, though mounting of the exhaust pipe assembly  12  with the bellows pipe of the related art exhaust type dryer is easy, the bellows pipe is susceptible to an external impact, and difficult to secure to a wall. 
   Moreover, the bellows pipe having a plurality of pipes attached together, or a long straight pipe, is liable to fail to exhaust to the outside of room perfectly, but have the exhaust air leaked into the room depending on adhered state of the tapes, or has difficulty in mounting because change of direction of the pipe is not possible. Moreover, the difficulty in adjustment of a total length of the exhaust pipe assembly causes to require much time in mounting the dryer. 
   In the meantime, the bellows pipe  13  is mounted along the wall ‘W’, and the hood exhaust pipe  20  is passed through the wall ‘W’ for discharging the exhaust air to the outside of room. 
   However, the related art exhaust type dryer has a problem in that the hood exhaust pipe  20  passed through the wall ‘W’ is susceptible to damage by friction with the wall ‘W’ if the hood exhaust pipe  20  shakes by the exhaust air or an outdoor wind. 
   Moreover, there can be infiltration of rain between the wall ‘W’ and the exhaust pipe  20 , and the exposure of a pass through hole in the wall ‘W’ for pass through of the hood exhaust pipe  20  is liable to impair an outside appearance of exterior or interior. 
     FIG. 2  illustrates an enlarged perspective view of “A” part in  FIG. 1 , i.e., a hood exhaust pipe of the related art dryer. 
   Referring to  FIG. 1  or  2 , the hood exhaust pipe  20  of the related art dryer has one end connected to the bellows pipe  13  on a side of a dryer body, and the other end passed through the wall, and opened to outside of room to form an end of the exhaust pipe assembly  12 . 
   The exhaust pipe assembly  12  has an opening EO opened fully to an outside of room, at an end thereof, i.e., at the other end of the hood exhaust pipe, and exhaust holes  21  in an outside circumference of the other end, for discharging the exhaust air through the opening and the exhaust holes in a direction of arrows ‘E’. 
   However, the fully opened opening EO for discharging the exhaust air to an outside of room is liable to drop a performance of the dryer  10  due to failure in smooth discharge of the exhaust air if an against wind rushes to an inside of the hood exhaust pipe  20 . Moreover, the possible entrance of birds, or mouse or dirt through the opening in the hood exhaust pipe is liable to damage the hood exhaust pipe  20 , or impair a performance of the dryer.

   Moreover, the end cap  52  forms the space ‘II’, and is connected to the hood exhaust pipe  30  with the connection members  54 , and the hood exhaust pipe  30  may not have the exhaust holes  31 . In this case, the exhaust air is discharged through the space ‘II’. 
   Because the end cap  32  or  52  is connected to the opening in the hood exhaust pipe  30 , the hood exhaust pipe of the exhaust pipe assembly of the present invention serves to prevent birds, and mice from entering into the hood exhaust pipe  30  through the opening in the hood exhaust pipe  30 . 
   As has been described, the exhaust type dryer of the present invention has the following advantages. 
   First, because height adjustment and direction change of the exhaust pipe assembly is possible, a dryer can be provided, which can be installed easily, and the exhaust pipe assembly can be fastened more firmly. 
   Second, the hood guide mounted on the wall having the hood exhaust pipe passed therethrough enables to prevent the hood exhaust pipe from shaking, to improve reliability of the product. 
   Third, the hood guide enables to provide fine inside and outside views of the building, as well as to prevent infiltration of water through a pass through hole having the hood exhaust pipe passed therethrough. 
   Fourth, a dryer having reliability thereof improved can be provided by making the exhaust air discharged from the hood exhaust pipe smoothly, preventing against wind from entering into an inner side of the hood exhaust pipe, and preventing animals or foreign matters from entering into the hood exhaust pipe. 
   It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
