The invention provides a refrigerator. The refrigerator can comprise a storage chamber, a cold air channel for providing cold air and a top air channel. The top air channel is arranged on the top wall of the storage chamber, and is provided with a rear-end air inlet, a front-end air inlet and a mixed flow air outlet with a downward opening. According to the configuration of the top air channel, the cold air blown out of the cold air channel is received by the rear-end air inlet, return air returned from the storage chamber is received by the front-end air inlet, and the cold air and the return air are mixed through the mixed flow air outlet to flow into the storage chamber. Due to the fact that the refrigerator is provided with the top air channel, the cold air and the high-temperature return air in the storage chamber can be mixed firstly, and then blown into the storage chamber, and even distribution of cold capacity/temperature in the storage chamber is accelerated; and fast refrigeration and even refrigeration are achieved, and the refrigeration efficiency is high.
