Abstract:
1. A clothes dryer, comprising: a drum to accommodate clothes; an air suction line to suck air into the drum; an air exhaust line to exhaust air from the drum; a heat pump circuit including a compressor, a radiator, a pressure reducer, and a heat absorber, wherein the heat absorber is provided in the air exhaust line, and the radiator is provided in the air suction line; a first blowing mechanism provided in the air exhaust line; a second blowing mechanism provided in the air suction line; a heater arranged downstream of the radiator in the air suction line; and a controller to control the first and second blowing mechanisms, wherein the controller controls an air blowing rate of the second blowing mechanism, based on an internal pressure of the drum, a refrigerant temperature of the heat absorber, and a refrigerant pressure of the radiator, and wherein the controller stops the heater when the radiator has a refrigerant pressure not less than a predetermined pressure causing the second blowing mechanism to have a maximum air blowing rate.
