Drying system of washing machine

A drying system of a washing machine comprises a washing barrel, a condenser, a fan, an air duct and a water inlet box, one end of the condenser is connected with one end of the air duct, the other end of the condenser is connected with the washing barrel, the fan is arranged in the air duct, the other end of the air duct is connected with the washing barrel, and the water inlet box is connected with the washing barrel and communicated with air outside the washing machine. The condenser is communicated with air outside the washing machine. According to the drying system, dry and cold air outside the machine can be sucked into the condenser, the condensation efficiency of the condenser is improved, meanwhile, part of humid and hot air in the washing barrel is exhausted into the water inlet box through the exhaust pipe to be condensed and exhausted out of the machine, equivalently, one more condenser is arranged, and therefore the drying efficiency is greatly improved, and the energy consumption is reduced.
