Combined washer and dryer

Abstract

A combined washer and dryer includes: a cabinet; a tub with a front opening at the laundry inlet and a rear opening; a drum; and a drying device arranged above the tub and configured to supply heated air toward the front opening. The drying device includes: a heat exchanger; a compressor; an inlet flow duct to guide air flowing in through the rear opening toward the heat exchanger; a supply flow duct to guide the air passing through the heat exchanger to be discharged forward; and a blowing fan configured to supply the air discharged from the supply flow duct to the front opening. In addition, the combined washer and dryer may further include: a ventilation hole at a rear surface of the cabinet corresponding to a position where the drying device is disposed; and a cooling fan disposed in the ventilation hole and supplying outside air to the compressor.

What is claimed is: 
     
         1 . A combined washer and dryer comprising:
 a cabinet with a laundry inlet at a front surface thereof;   a tub, arrangeable inside the cabinet, with a front opening such that while the tub is arrange inside the cabinet, the front opening of the tub is at the laundry inlet of the cabinet,   the tub including a rear opening;   a drum rotatable inside the tub; and   a drying device, arrangeable above the tub, configured to supply heated air toward the front opening,   wherein the drying device comprises:   a heat exchanger including an evaporator and a condenser;   a compressor, arrangeable behind the heat exchanger, configured to compress and circulate refrigerant of the heat exchanger;   an inlet flow duct arrangeable on one side of the heat exchanger such that while the inlet flow duct is arranged on the one side of the heat exchanger, air flowing in through the rear opening of the tub is guided toward the heat exchanger through the inlet flow duct;   a supply flow duct arrangeable on another side of the heat exchanger such that while the supply flow duct is arranged on the other side of the heat exchanger, the air that has passed through the heat exchanger is guided through the supply flow duct to be discharged forward; and   a blowing fan configured to supply the air discharged from the supply flow duct to the front opening, and   wherein the combined washer and dryer further comprises:   a ventilation hole at a rear surface of the cabinet corresponding to a position where the drying device is arranged; and   a cooling fan arrangeable in the ventilation hole such that while the cooling fan is arranged in the ventilation hole, outside air is supplied to the compressor.   
     
     
         2 . The combined washer and dryer of  claim 1  further comprising:
 a blowing guide arrangeable in front of the cooling fan such that while the blowing guide is arranged in the in the front of the cooling fan, the outside air supplied by the cooling fan is guided toward the compressor. 
 
     
     
         3 . The combined washer and dryer of  claim 2 , wherein
 the blowing guide is formed as a hollow duct with both ends open, and one end of the blowing guide is in front of the cooling fan, and another end of the blowing guide is toward a side surface of the compressor.   
     
     
         4 . The combined washer and dryer of  claim 1 , wherein
 the ventilation hole is at the rear surface of the cabinet corresponding to the position where the compressor is disposed so that a direction of air supplied by the cooling fan is toward the compressor.   
     
     
         5 . The combined washer and dryer of  claim 1 , wherein
 a rotation axis of the cooling fan is along the compressor so that a direction of air supplied by the cooling fan is toward the compressor.   
     
     
         6 . The combined washer and dryer of  claim 1 , further comprising:
 a heat sink arrangeable on a side surface of the compressor such that while the heat sink is arranged on the side surface of the compressor heat from the compressor dissipated.   
     
     
         7 . The combined washer and dryer of  claim 6 , wherein
 the heat sink is arranged in a direction toward the cooling fan on the side surface of the compressor.
