Description

Indoor unit of air conditioner Technical Field The utility model belongs to the technical field of air conditioners, and particularly relates to an air conditioner indoor unit. Background The key components for realizing heat exchange of the air conditioner indoor unit are a heat exchanger and a fan assembly, when the air conditioner indoor unit operates, the fan assembly generates a certain directional airflow, and the airflow flows through the heat exchanger to generate heat exchange with the refrigerant inside and then is output to the room, so that the purpose of adjusting the indoor temperature is realized. When the fan assembly sends wind, the air flow output from the fan assembly contacts with the positions of two sides of the spiral case to form reflection to generate a certain degree of cross wind component, the air flow contacts with the upper wall and the lower wall of the air outlet to form a certain reflection air flow, the cross wind volume meets with the reflection air flow to generate vortex, the vortex acts on the fins to generate fin sound, working noise in the indoor unit of the air conditioner is increased, user experience is influenced, the fin sound is improved in part of the air conditioner by means of reducing the wind speed, adjusting the angle of the heat exchanger, expanding the distance between the fins, changing the shape of the spiral case and the like, and the improvement mode has the problems of high transformation cost, low heat exchange efficiency and the like.
