Abstract

This clothes dryer (1) is provided with a drying chamber (9), an air path (10), a heat pump device (7) which is provided inside of the air path (10) and which is linked to a condenser (3) and an evaporator (5) by a conduit (6) circulating a coolant, a fan (8) which blows air in the air path (10), a discharge unit (15) which discharges water towards the evaporator (5), a storage tank (13) which stores dehumidification water generated by the evaporator (5), and a control unit (20). Futher, the control unit (20) performs control such that, after water has been discharged from the discharge unit (15), the dehumidification water stored in the storage tank (13) is discharged into the evaporator (5). By this means, lint is removed and water containing scale components attached to the evaporator (5) is flushed by the dehumidification water stored in the storage tank (13).

Description

technical field [0001] The present invention relates to a clothes dryer for drying objects to be dried, such as clothes, and a method for cleaning an evaporator of the clothes dryer. Background technique [0002] Conventionally, with regard to clothes dryers equipped with heat pump devices, lint generated from fabric products such as clothes is mixed into drying air. The mixed lint adheres to the air blower, heat exchanger, etc. installed in the circulation air duct, and accumulates. As a result, it becomes the cause of the function reduction of a blower and a heat exchanger. Therefore, the conventional clothes dryer is provided with a lint filter for trapping the lint mixed in the drying air in the circulating air duct. [0003] However, since the drying air flowing in the circulation duct needs to ensure a constant air flow rate, the mesh of the lint filter cannot be made finer. Therefore, it is difficult to use the lint filter to completely remove the lint from the dry...
