摘要： A refrigerator includes a flow path exit of a fluid introduction part and a flow path entrance of the frost detection duct that have a same size. Thus, defrost water flowing down into the fluid introduction part through a guide flow path may more efficiently flow downward without becoming stagnant and freezing of the stagnant water may be prevented.

摘要： A refrigerator is configured such that a controller may control the frost detecting operation to be differently performed on the basis of at least one of a room temperature and a set reference temperature. Thus, precise frosting detection may be performed and power consumption due to the frosting detection may be minimized, and power consumption efficiency may be improved.

摘要： A refrigerator includes a first heater, a second heater, and a third heater, and the third heater is located inside a frost detection flow path and generates heat. Accordingly, during a defrosting operation, the inside of the frost detection flow path may be prevented from being blocked. Or freezing of the frost check sensor provided in the frost detection flow path may be prevented.

摘要： A fluid inlet part of a frosting detection duct protrudes toward a flow path of a fluid to provide flow path resistance. Accordingly, a material property detected by a frosting detecting device may secure the discrimination sufficient to additionally recognize frosting-related information in addition to detecting frosting.
