Abstract

The present invention relates to a laundry dryer (1 ) comprising a drum (2) wherein the laundry is placed, a drying duct (3) wherein the process air is circulated, a heater (4) that heats the process air, a condenser (5) that condenses the process air, a process air fan (6) that circulates the process air in the drying duct (3), a cooling fan (7) that cools the condenser (5), a motor (8) that drives the process air fan (6) and the cooling fan (7) together, a cooling duct (9) that directs the air sucked from the outer environment by the cooling fan (7) onto the condenser (5) and a thermoelectric heat pump (12) disposed in the drying duct (3), having a cold side (10) that condenses the process air passing thereover by cooling and a hot side (1 1 ) that heats the process air passing thereover.

Description

technical field [0001] The present invention relates to a laundry dryer which includes a thermoelectric heat pump and wherein energy is saved by increasing the efficiency of the thermoelectric heat pump. Background technique [0002] In the laundry dryer in which drying air is circulated in a closed cycle, the drying air activated by a fan is passed through the laundry to remove moisture from the laundry, and water vapor in the air is condensed at the condenser. The dry air dehumidified at the condenser is then passed through the heater to be heated, and the hot and dry air is delivered to the laundry. In the prior art, besides the condenser and the heater, a thermoelectric heat pump, also called a Peltier element, is also used in the laundry dryer. A thermoelectric heat pump has a hot side and a cold side, and performs both functions of condensing the dry air by cooling and heating the dry air. The hot side of a thermoelectric heat pump used in a clothes dryer supports th...
