Abstract

The invention relates to the technical field of air outlet noise reduction of air conditioners in cabs, in particular to an air outlet device, an air conditioner and engineering machinery. The air outlet device comprises an air outlet structure, wherein the air outlet structure comprises an air outlet body with an air outlet and an air baffling plate arranged inside the air outlet; an airflow flows through the air outlet and flows out of the air conditioner; the air baffling plate adjusts the opening degree of the air outlet by changing the angle relative to the air outlet body; the air outlet device further comprises an air outlet noise-reducing device; the air outlet noise-reducing device can reduce noise at the air outlet structure; the air outlet noise-reducing device is arranged at the upstream of the air outlet structure in the outflowing direction of the airflow. The air outlet device can treat the airflow by using the air outlet noise-reducing device before the airflow reaches the air outlet structure, so that the noise at the air outlet structure is relatively reduced, the noise intensity in a cab is reduced, and the sound quality in the cab is improved.

Description

technical field [0001] The invention relates to the technical field of air outlet and noise reduction of cab air conditioners, in particular to an air outlet device, an air conditioner and construction machinery. Background technique [0002] The air outlet structure of the cab air conditioner is a standard part widely used in construction machinery. It usually includes an air outlet body with an air outlet and a windshield installed in the air outlet. The air flows out to the air conditioner through the air outlet. The outside, and the windshield can adjust the opening size of the air outlet by changing the angle relative to the air outlet body. [0003] In the prior art, construction machinery often adopts a structure in which several air outlets share a main air supply pipe to supply air through the split chamber. When the main air supply pipe supplies air to each air outlet, there is no flow guide device, the turbulent flow is obvious, and the airflow is A large amount ...
