Clothes dryer

Abstract

A clothes dryer includes a cabinet having a front surface with an opening in the front surface; a drum inside the cabinet and configured so that objects to be dried are insertable through the opening to be received in the drum; a heat exchanger; and a door to open and close the opening, and including a ventilation member, wherein the door is configured so that, with the door being in an open state, the ventilation member covers at least a portion of the opening so that the ventilation member prevents objects in the drum from moving through the opening, air passing through the heat exchanger is discharged from the drum, through the ventilation member and the opening, to an outside of the cabinet, and outside air is supplied through the ventilation member and the opening to the heat exchanger.

What is claimed is: 
     
         1 . A clothes dryer, comprising:
 a cabinet having a front surface with an opening in the front surface;   a drum inside the cabinet and configured so that objects to be dried are insertable through the opening to be received in the drum;   a heat exchanger; and   a door to open and close the opening, and including a ventilation member,   wherein the door is configured so that, with the door being in an open state, the ventilation member covers at least a portion of the opening so that:
 the ventilation member prevents objects in the drum from moving through the opening, 
 air passing through the heat exchanger is discharged from the drum, through the ventilation member and the opening, to an outside of the cabinet, and 
 outside air is supplied through the ventilation member and the opening to the heat exchanger. 
   
     
     
         2 . The clothes dryer of  claim 1 , wherein
 the ventilation member is arranged between the door and the opening, and includes at least one of a mesh and a grill.   
     
     
         3 . The clothes dryer of  claim 1 , wherein
 the door includes:
 a first door configured to be rotatable and to seal an outer edge of the opening, and having a door opening formed in the first door, and 
 a second door coupled to the first door, and configured to be rotatable in front of the first door to open and close the door opening of the first door, 
 wherein the ventilation member is arranged in the first door so as to cover at least a portion of the door opening. 
   
     
     
         4 . The clothes dryer of  claim 1 , wherein
 the door includes:
 a first door including a hole formed by penetrating at a portion of the first door, and 
 a second door coupled to the first door so as to be rotatable to open and close the hole, 
 wherein the ventilation member is arranged in the hole. 
   
     
     
         5 . The clothes dryer of  claim 1 , wherein
 the ventilation member includes:
 a separation prevention member to connect between the door and the opening. 
   
     
     
         6 . The clothes dryer of  claim 5 , wherein
 the separation prevention member includes:
 a plurality of ribs connected between the door and the opening. 
   
     
     
         7 . The clothes dryer of  claim 1 , further comprising:
 an automatic opening and closing device configured to control the door to open the opening, and   a controller configured to control the automatic opening and closing device,   wherein the controller is configured to control the automatic opening and closing device to control the door to be open in a dehumidification mode.   
     
     
         8 . The clothes dryer of  claim 7 , further comprising:
 a door sensor configured to detect the open state and a closed state of the door,   wherein the controller is configured to control the automatic opening and closing device to control the door to move to the open state in response to detecting the door being in the closed state in the dehumidification mode.   
     
     
         9 . The clothes dryer of  claim 7 , wherein
 the controller is configured to control a motor to rotate the drum in the dehumidification mode.   
     
     
         10 . The clothes dryer of  claim 7 , wherein
 the door includes:   a first door configured to be rotatable to seal an outer edge of the opening, and having a door opening formed in the first door, and   a second door coupled to the first door, and configured to be rotatable in front of the first door to open and close the first door,   wherein the controller is configured to control the automatic opening and closing device to allow the second door to be open in response to detecting the second door being closed in the dehumidification mode.   
     
     
         11 . The clothes dryer of  claim 1 , wherein
 the door is at least partially opened in the open state so that the opening is not fully closed.   
     
     
         12 . The clothes dryer of  claim 1 , wherein
 a closable door opening formed in the door is at least partially opened in the open state so that the opening is not fully closed by the door.
