Title:

REFRIGERATOR AND METHOD FOR CONTROLLING SAME

Document Type and Number:

WIPO Patent Application WO/2019/190114

Kind Code:

A1

Abstract:

A method for controlling a refrigerator according to an embodiment of the present invention comprises the steps of: operating, for a set duration, a heating element of a sensor disposed on a bypass channel which allows air to bypass an evaporator disposed in a heat-exchange space; sensing the temperature of the heating element in on or off state; and sensing the blockage of an air channel in the heat-exchange space on the basis of the difference in value of the temperature between a first sensed temperature (Ht1), which is the lowest value, and a second sensed temperature (Ht2), which is the highest value, from among the sensed temperatures of the heating element.
