Title: Wind guide assembly of air conditioner
Inventor: LI WENBO
IPC: F24F13/08
Filed: 2020-04-10
Abstract: The present invention relates to the technical field of air conditioners, and specifically relates to a wind guide assembly of an air conditioner. The wind guide assembly comprises a wind guide plate, a first inclined member, a second inclined member, a wind guide protrusion and a wind guide track. When the wind guide plate is opened, the wind guide plate guides airflow to flow along a set wind guide angle by means of the first inclined member so as to increase the amount of airflow on the windward side of the wind guide plate. The wind guide protrusion may guide part of the airflow within a housing to the vicinity of a leeward port portion. The second inclined member may expand the amount of airflow of the leeward port portion, and facilitate the airflow guided by the wind guide protrusion flowing into the leeward port portion while intercepting part of the airflow and causing same to flow into the leeward port portion. The wind guide track may guide the airflow of the leeward port portion to flow along the leeward surface of the wind guide plate, thereby ensuring that the side airflow flows along the first inclined member, while increasing the amount of airflow on the leeward side of the wind guide plate, thus ensuring the overall flow stability of the airflow. Thus, the wind discharge effect of an air conditioner is improved, and the phenomenon of condensation is alleviated for the wind guide plate.
