Air-cooled refrigerator

Abstract

The invention provides an air-cooled refrigerator comprising an air duct and a sterilization and deodorization device arranged in the air duct. The air duct is provided with an air inlet and an air outlet. The sterilization and deodorization device comprises a photocatalyst filter screen and an illuminant with the projection direction facing the photocatalyst filter screen. The photocatalyst filter screen is arranged close to the air inlet and disposed on the inner side of an air door of the air inlet, and comprises a main acting surface used for receiving projection of the illuminant and a back surface opposite to the main acting surface. At least one of the main acting surface and the back surface is parallel to the flow direction of cold air flow in the air duct, so that the sterilization and deodorization device is free of blocks to the cold air flow entering the air duct, effectively prevents water mist and has no condensation; meanwhile, on the premise that refrigeration effect of the air-cooled refrigerator is unaffected, the cold air flow entering the air duct is effectively sterilized, and sterilization effect is obvious.

Description

technical field [0001] The invention relates to an air-cooled refrigerator, in particular to an air-cooled refrigerator which does not affect the cooling effect. Background technique [0002] A refrigerator is a device that uses refrigeration to keep the interior of the refrigerator at a low temperature to preserve food, but the refrigerator freezer is prone to breed bacteria after long-term use. In order to prevent the food stored in the freezer compartment of the refrigerator from rotting after a long period of storage, a sterilizing and deodorizing device is usually placed at the air inlet of the refrigerator compartment air duct in existing refrigerators to effectively detoxify the cold air entering the freezer compartment. Filter to achieve antibacterial, fresh-keeping and deodorizing effects. [0003] Ultraviolet rays can effectively kill bacteria and tiny viruses, which have been widely used in medical and food industries. The existing sterilizing and deodorizing de...

Problems solved by technology

[0004] However, the existing sterilization and deodorization devices usually set the photocatalyst filter screen at a certain angle with the flow direction of the cold air flow in the refrigerator, which not only has a certain blocking effect on the cold air flow entering the refrigerator, but also affects the performance of the refrigerator refrigerator. Cooling effect; at the same time, after long-term use of the above-mentioned sterilization and deodorization device, the fog on the photocatalyst filter is easy to accumulate, which will cause the photocatalyst filter to be frozen
