  The present invention is characterized in that, in the clothes dryer 1, exhaust gas in a high temperature state is reused for clothes drying. Hereinafter, embodiments of a clothes dryer 1 according to the present invention will be described in detail with reference to the drawings.

  In addition, the clothes dryer 1 concerning this invention is not limited to embodiment described below or the structure shown in figure, It can change suitably in the range which does not deviate from the meaning and structure of this invention.

FIG. 1 is an overall view showing an embodiment of a clothes dryer 1 according to the present invention.
That is, the clothes dryer 1 includes a rotating drum 2, a heater H, and a vacuum B.

  The rotating drum 2 is a portion that accommodates the wet clothes after washing, and is a substantially cylindrical shape that is rotated by a motor.

  The heater H is a portion that generates high-temperature air A2 for drying wet clothes accommodated in the rotary drum 2. That is, by using a heat source such as electricity, gas, kerosene or the like, the air A1 taken from the outside is heated to generate high-temperature air A2 for supplying air to the rotating drum 2.

  The vacuum B supplies the high temperature air A2 heated by the heater H into the rotary drum 2 through the air supply path, and the high temperature air A2 supplied into the rotary drum 2 through the exhaust path 3. For exhausting A3 to the outside. The vacuum B is located behind the rotary drum 2 when viewed from a series of air flows from the air A1 to the exhaust A3. That is, the vacuum B takes in the air A1 from the outside to the heater H, sends the high-temperature air A2 generated by the heater H into the rotating drum 2, and further exhausts the high-temperature air A2 in the rotating drum 2 to the exhaust 3 Will act.

  In the clothes dryer 1 having the above-described configuration, the present invention employs a configuration in which a drawing path 4 is provided that communicates a predetermined intermediate position in the exhaust path 3 connected to the vacuum B and the rotating drum.
