         2 . The dryer of  claim 1 , wherein the heat exchanger is composed by a sensible heat exchanger  20 , wherein the sensible heat exchanger  20  has plural heat exchange plates  24  arranged parallel at an air inlet passage of the air flow chamber  14 , wherein the heater  40  is a PCT heater, wherein the blowing fan  30  is arranged at a position facing the sensible heat exchanger  20 , whereby the air flowing into the air inlet of the dryer body  10  is supplied to the PCT heater through the sensible heat exchanger  20 . 
     
     
         3 . The dryer of  claim 2 , wherein the air flow chamber  14  comprises an upper flow chamber  14   a  provided at the dryer body  10  so as to be arranged at the upper side of the drying chamber  12 , and a side flow chamber  14   b  provided at the dryer body  10  by being communicated to the upper flow chamber  14   a  so as to be extended upward and downward,
 wherein the sensible heat exchanger  20  and the blowing fan  30  are provided at the upper flow chamber  14   a  and at the same time the sensible heat exchanger  20  is communicated with the drying chamber  12  of the dryer body  10 , 
 wherein the PCT heater is embedded in the side flow chamber  14   b  so as to be arranged at the position of a stage next to the blowing fan  30 , 
 whereby the hot wind is supplied to the drying chamber  12  through a hot wind inlet hole  16   h  formed at a hot wind inlet panel  16  comprising the drying chamber  12 . 
 
     
     
         4 . The dryer of  claim 3 , wherein the sensible heat exchanger  20  is composed so that the plural heat exchange plates  24  are arranged parallel adjoining each other, wherein the heat exchange plates  24  have spacing protrusions  25  which protrude from one side thereof to the other side, whereby the adjoining heat exchange plates  24  secure a space through which the air passes by means of the spacing protrusions  25 . 
     
     
         5 . The dryer of  claim 1 , wherein the air flow chamber  14  is provided at the perimeter of the drying chamber  12  of the dryer body  10 , wherein the sensible heat exchanger  20  is embedded in the air flow chamber  14  so as to be communicated with the drying chamber  12 , wherein the sensible heat exchanger  20  has a guider  50  which lets the hot wind flowing into the sensible heat exchanger  20  from the drying chamber  12  to be re-circulated to the sensible heat exchanger  20 . 
     
     
         6 . The dryer of  claim 1 , wherein an air circulation pipe  60  which passes the inside of the drying chamber  12  and the hollow part of the inside of which is communicated with the outside air of the dryer body  10  is further provided at the dryer body  10 . 
     
     
         7 . The dryer of  claim 1 , further comprising an adjustment pipe  70  which, by being communicated with the bottom part  12   a  provided at the drying chamber  12  of the dryer body  10 , maintains the pressure in the drying chamber  12  by maintaining the water generated at the time of drying the drying object  6  to a predetermined water level in the drying chamber, and discharging the water to outside when the water level is at or higher than the predetermined water level. 
     
     
         8 . The dryer of  claim 5 , wherein the bottom part  12   a  composing the drying chamber  12  is gradually inclined downward toward the center part of the dryer body  10 , wherein the adjustment pipe  70  is composed so that a connection sleeve part  73  is connected between a first sleeve part  72  and a second sleeve part  74 , wherein the first sleeve part  72  is connected to the center part of the bottom part  12   a  of the drying chamber  12 , and wherein the upper end of the second sleeve part  74  is arranged at a position relatively lower than the upper end of the first sleeve part  72 .
