Abstract

The present disclosure relates to a dryer having a waste heat recovery means, and according to an aspect of the present disclosure, the dryer having the waste heat recovery means, includes a cabinet; a drum rotatably mounted within the cabinet; an intake duct configured to form an intake flow path for flowing air into the drum; an exhaust duct configured to exhaust air out of the cabinet from the drum; a heater configured to heat air flowing into the drum; and an ambient air duct configured to inhale air outside the cabinet and supply the air into the drum. The waste heat recovery means comprising an evaporator configured to absorb the heat of air being exhausted from the drum, the evaporator comprising an evaporation unit configured to absorb the heat of air being exhausted from the drum, a condenser unit configured to transfer heat absorbed from the evaporation unit to ambient air flowing into the ambient air duct, and a heat transfer medium configured to transfer heat between the evaporation unit and condenser unit, wherein the ambient air duct is communicated with the intake duct between the drum and heater.

Description

technical field [0001] The present invention relates to a dryer having a waste heat recovery unit, and more particularly to a dryer having a unit capable of recovering and reusing heat energy contained in air exhausted from the dryer. Background technique [0002] Generally, for a clothes processing device with a drying function such as a washing machine or a dryer, the laundry that has been washed and dehydrated is put into the drum, and hot air is supplied to the inside of the drum to dehydrate the laundry. Evaporates, thus drying the laundry. [0003] Taking the double dryer as an example, the above-mentioned dryer includes: a drum, which is rotatably arranged inside the body, and is used for putting in laundry; a driving motor, which is used to drive the drum; and a blower fan, which is used to Air is blown into the inside of the drum; a heating unit for heating the air flowing into the inside of the drum. In addition, the heating means may utilize high-temperature res...
