The horizontal refrigerator is a refrigeration device which keeps constant low temperature, is a common electric appliance for preserving articles at low temperature in life, and is widely applied to the fields of commerce and household.

At present, the refrigeration principle of horizontal refrigerators is generally divided into direct-cooling horizontal refrigerators and air-cooling horizontal refrigerators, wherein the direct-cooling horizontal refrigerators are prone to frost in the refrigerator during use, and the air-cooling horizontal refrigerators are favored by users due to the fact that the air-cooling horizontal refrigerators have the advantage of no frost. In the air-cooled horizontal refrigerator, air with lower temperature is blown into the accommodating space through the air supply device (namely, the air supply device supplies air to the accommodating space) so as to refrigerate articles stored in the accommodating space, and then the air with higher temperature is sucked away through the air suction device (namely, the air suction device sucks air from the accommodating space).

Therefore, in the air-cooled horizontal refrigerator, how to uniformly cool the articles stored in the accommodating space becomes a problem to be solved.

Here, the air blowing device 17 includes at least a first group of air blowing ports 17A and a second group of air blowing ports 17B, and the air suction device 18 includes at least a first group of air suction ports 18A and a second group of air suction ports 18B.

Here, when in use, the air with lower temperature is blown out from the first and second groups of air blowing openings and enters the accommodating space 11 (the accommodating space 11 surrounded by the liner 1), and the air with lower temperature flows from top to bottom and flows from the first liner wall 13 to the second liner wall 14, and in this process, the air flows through most of the articles in the accommodating space 11 with high probability, and then flows out from the first and second groups of air suction openings, so that the articles stored in the accommodating space 11 can be uniformly cooled.

Here, in the air-cooled horizontal freezer according to the embodiment of the present invention, the air with a relatively low temperature sent from the first set of air blowing openings 17A flows downward from the first inner container wall 13 to the second inner container wall 14 from top to bottom, and is sucked away by the first set of air suction openings 18A with a high probability, that is, the articles on the upper layer of the accommodating space 11 are cooled; the air with lower temperature sent by the second group of air supply openings 17B flows downwards along the direction from the top to the bottom from the first liner wall 13 to the second liner wall 14, and is sucked away by the second group of air suction openings 18B with a high probability, that is, the articles located at the lower layer of the accommodating space 11 are cooled. So that the articles stored in the accommodating space 11 can be uniformly refrigerated.
