DUCT FOR DRUM-TYPE WASHING MACHINE COMBINED WITH DRYING FUNCTION FOR OBTAINING STRUCTURE EFFECTIVELY PROTECTING TEMPERATURE SENSOR INSTALLED IN DUCT FROM COOLANT

摘要

PURPOSE: A duct of a drum-type washing machine combined with a drying function is provided to obtain an exact and subdivided washing amount determination value by using a temperature change occurring in a duct for condensation and to achieve the degree of dryness desired by a user according to the determined washing amount value. CONSTITUTION: A duct(120) of a drum-type washing machine combined with a drying function comprises a tub in which a drum is rotatably installed; a hot blast supply unit blowing heated air of high temperature into the tub; the duct vertically installed to a side of the tub to have one end communicating with the lower part of the tub and the other end communicating with a side of the tub to constitute a passage for circulation of air of high temperature produced by the hot blast supply unit; and a coolant supply pipe communicating with the upper end part of the duct to supply a coolant to the inside of the duct. The duct of the drum-type washing machine has plural temperature sensors each installed to the upper part and lower part of the inside of the duct, and a coolant guide passage(122) guiding the coolant supplied from the coolant supply pipe to the lower end part of the duct to prevent the coolant from coming in contact with the temperature sensors.
