Problems solved by technology

For the automobile front defrosting and defogging device with this structure, since the left air duct, central air duct and right air duct are split, they are connected by clips, and the central air duct is higher than the left air duct and right air duct as a whole. The direction of the air outlets on the left air duct, central air duct and right air duct is inconsistent, so the manufacturing process is complicated, and the sealing effect and defrosting and defogging are not good

Abstract

The invention discloses a defrosting and demisting device for an automobile. The defrosting and demisting device for an automobile consists of an air duct assembly and an air guide grating assembly. The air duct assembly comprises a left air duct, a central air duct and a right air duct which are integrally structured. The air guide grating assembly comprises a left air guide grating, a central air guide grating and a right air guide grating which are arranged on an instrument board. A left air outlet of the left air duct corresponds to the left air guide grating, a central air outlet of the central air duct corresponds to the central air guide grating, and a right air outlet of the right air duct corresponds to the right air guide grating, and sponge strip seals are arranged in corresponding positions. As the left air duct, the central air duct and the right air duct are integrally structured, the defrosting and demisting device for the automobile provided by the invention has a good sealing effect. As the left air duct, the central air duct and the right air duct are consistent in height, the defrosting and demisting device for the automobile provided by the invention is easier to process; and as the air outlets of the left air duct, the central air duct and the right air duct are consistent in orientation, the air duct is easy to open a mould and has a good mold stripping effect.

Description

technical field [0001] The invention relates to an automobile air-conditioning system, in particular to an automobile defrosting and defogging device. Background technique [0002] The defrosting and defogging device for automobiles mainly includes two parts: the defrosting and defogging duct and the grille. The Chinese patent No. 201120239675.3 discloses a defrosting and defogging device in front of a car, which includes an air duct and a grille. The air duct is composed of a left air duct, a central air duct and a right air duct, and the left air duct, the central air duct and the right air duct are split structures; they are connected by clips. The central air duct is overall higher than the left air duct and the right air duct. There are corresponding left air outlet, middle air outlet and right air outlet respectively on the left air duct, central air duct and right air duct; The air outlet is at an oblique angle. The air conduction grille is fixed on the instrument...
